Non-small cell lung cancer (NSCLC) presents the greatest number of identified therapeutic targets, some of which have therapeutic utility. Currently, detecting EGFR, BRAF, KRAS and MET mutations, ALK, ROS1, NTRK and RET translocations, and PD-L1 expression in these patients is considered essential. The use of next-generation sequencing facilitates precise molecular diagnosis and allows the detection of other emerging mutations, such as the HER2 mutation and predictive biomarkers for immunotherapy responses. In this consensus, a group of experts in the diagnosis and treatment of NSCLC selected by the Spanish Society of Pathology and the Spanish Society of Medical Oncology have evaluated currently available information and propose a series of recommendations to optimize the detection and use of biomarkers in daily clinical practice.

Afatinib; Carcinoma, Squamous Cell; Pembrolizumab Afatinib; Carcinoma de células escamosas; Pembrolizumab Afatinib; Carcinoma de cèl·lules escamoses; Pembrolizumab Introduction Afatinib and pembrolizumab have separately shown survival benefit in patients with squamous cell carcinoma (SqCC) of the lung, and there is biological rationale for concurrent inhibition of the programmed death ligand-1 and epidermal growth factor receptor (EGFR) pathways in this patient population. Materials and Methods This open-label, single-arm study enrolled patients with SqCC of the lung who had progressed during/after first-line chemotherapy and comprised two parts: a safety run-in to establish the recommended phase II dose (RP2D; afatinib 40 mg or 30 mg once daily with pembrolizumab 200 mg every 3 weeks); and the main part assessing efficacy and safety of the RP2D. The primary endpoint was objective response rate (ORR); secondary endpoints included the RP2D, progression-free survival (PFS) and overall survival (OS). Results Twenty-four patients were treated in the safety run-in (afatinib 40 mg/30 mg cohorts: n = 12/12). Median age was 63.5 years; 79.2% of patients were male. All patients discontinued afatinib and pembrolizumab, most commonly due to disease progression (58.3% and 75.0%, respectively) or adverse events (AEs; 37.5% and 25.0%, respectively). The study was discontinued early after completion of the safety run-in, and no patients entered the main part. ORR was 12.5%; median PFS and OS were 13.1 and 29.3 weeks, respectively. All patients had ≥ 1 drug-related AE (grade ≥ 3: 45.8%). Conclusion While there were no new or unexpected safety findings, exploratory analysis of antitumor activity indicated limited efficacy with afatinib plus pembrolizumab in patients with SqCC of the lung who had progressed during/after first-line chemotherapy.

5 figures, 5 tables.-- Supplementary information available., (1) Despite the effectiveness of immune checkpoint inhibitors (ICIs) in lung cancer, there is a lack of knowledge about predictive biomarkers. The objective of our study is to analyze different subsets of T-lymphocytes and natural killer (NK) cells as predictive biomarkers in a cohort of patients with nonsmall cell lung cancer (NSCLC) treated with ICI. (2) This is an observational, prospective study with 55 NSCLC patients treated with ICI. A total of 43 T and NK cell subsets are analyzed in peripheral blood, including the main markers of exhaustion, differentiation, memory, activation, and inhibition. (3) Regarding the descriptive data, Granzyme B+CD4+ Treg lymphocytes stand out (median 17.4%), and within the NK populations, most patients presented cytotoxic NK cells (CD56+CD3−CD16+GranzymeB+; median 94.8%), and about half of them have highly differentiated adaptive-like NK cells (CD56+CD3−CD16+CD57+ (mean 59.8%). A statistically significant difference was observed between the expression of PD1 within the CD56bright NK cell subpopulation (CD56+CD3−CD16−PD-1+) (p = 0.047) and a better OS. (4) Circulating immune cell subpopulations are promising prognostic biomarkers for ICI. Pending on validation with a larger sample, here we provide an analysis of the major circulating T and NK cell subsets involved in cancer immunity, with promising results despite a small sample size., Work in the JP lab is funded by FEDER (Fondo Europeo de Desarrollo Regional, Gobierno de Aragón, Group B29_20R), Grant PID2020-113963RB-I00 by MICIN/AEI, CIBER—Consorcio Centro de Investigación Biomédica en Red—(CIBERINFEC, CB21/13/00087), Grant PTA2019-016739-I funded by MCIN/AEI/10.13039/501100011033 to PD, Instituto de Salud Carlos III, Aspanoa and Carrera de la mujer de Monzón.

Molecular testing for genomic variants is recommended in advanced non-small cell lung cancer (NSCLC). Standard tissue biopsy is sometimes infeasible, procedurally risky, or insufficient in tumor tissue quantity. We present the analytical validation and concordance study of EGFR variants using a new 17-gene liquid biopsy assay (NCT02762877). Of 144 patients enrolled with newly diagnosed or progressive stage IV nonsquamous NSCLC, 140 (97%) had liquid assay results, and 117 (81%) had both EGFR blood and tissue results. Alterations were detected in 58% of liquid samples. Overall tissue-liquid concordance for EGFR alterations was 94.0% (95% CI 88.1%, 97.6%) with positive percent agreement of 76.7% (57.7%, 90.1%) and negative percent agreement of 100% (95.8%, 100%). Concordance for ALK structural variants was 95.7% (90.1%, 98.6%). This assay detected alterations in other therapeutically relevant genes at a rate similar to tissue analysis. These results demonstrate the analytical and clinical validity of this 17-gene assay.

2 Figuras, 1 Tabla, Microbiota have emerged as key modulators of both the carcinogenic process and the immune response against cancer cells, and, thus, it seems to influence the efficacy of immunotherapy. While most studies have focused on analyzing the influence of gut microbiota, its composition substantially differs from that in the lung. Here, we describe how microbial life in the lungs is associated with host immune status in the lungs and, thus, how the identification of the microbial populations in the lower respiratory tract rather than in the gut might be key to understanding the lung carcinogenic process and to predict the efficacy of different treatments. Understanding the influence of lung microbiota on host immunity may identify new therapeutic targets and help to design new immunotherapy approaches to treat lung cancer.

Purpose This Delphi panel study assessed the level of consensus between medical oncologists on the clinical management of patients with early-stage EGFR-mutated non-small cell lung cancer (NSCLC). Methods A modified two-round Delphi approach was used. A scientific committee comprised of medical oncologists developed an online questionnaire. Delphi panel experts rated their level of agreement with each questionnaire statement on a 9-point Likert scale. The questionnaire included 36 statements from 3 domains (clinical management of early-stage NSCLC: 15 statements; role of adjuvant therapy in early-stage NSCLC: 9 statements; and role of adjuvant therapy in early-stage NSCLC with sensitizing EGFR mutation: 12 statements). Results In round 1, consensus was reached for 24/36 statements (66.7%). Nine statements that did not achieve consensus after the first round were evaluated in round 2, and none of them reached consensus. Overall, 84.4% of the panelists agreed that EGFR mutation testing should be done after surgery. Consensus was not achieved on whether the implementation of EGFR mutation testing in resected early-stage NSCLC could limit the use of adjuvant osimertinib. The panelists recognized the rationale for the use of osimertinib in the adjuvant scenario (88%) and 72% agreed that it may change the treatment paradigm in stage IB–IIIA EGFR-mutated NSCLC. Consensus was not reached on the inconvenience of prolonged duration of osimertinib. Conclusions This Delphi study provides valuable insights into relevant questions in the management of early-stage EGFR-mutated NSCLC. However, specific issues remain unresolved. The expert consensus emphasizes the role of adjuvant treatment with osimertinib in this scenario.

Background Afatinib is a selective, irreversible ErbB family blocker that has shown survival benefit in lung squamous-cell carcinoma (SCC) patients. Pembrolizumab, a humanized immunoglobulin G4 monoclonal antibody to the programmed cell death 1 (PD-1) receptor, has also shown survival benefit in lung SCC. Concurrent inhibition of the PD-1 and epidermal growth factor receptor (EGFR) pathways represents a rational approach to improve responses and delay the onset of treatment resistance in lung SCC. Trial Design This phase II, open-label, single-arm study ( NCT03157089 ) is designed to assess the efficacy and safety of afatinib in combination with pembrolizumab in patients with stage IIIB/IV lung SCC that has progressed during/after first-line platinum-based chemotherapy. Eligible patients must have ≥1 target lesion (as per Response Evaluation Criteria in Solid Tumors version 1.1) and must have not received previous immune checkpoint inhibitor/EGFR-targeted therapy. The recommended phase II dose (RP2D) and safety profile will be determined during a safety run-in with oral afatinib (starting dose, 40 mg/d) with intravenous pembrolizumab (200 mg every 3 weeks). In the main study, all patients will receive afatinib at the RP2D with pembrolizumab until disease progression, unacceptable toxicity, or for up to 35 cycles. The primary end point is objective response (complete + partial response). Other end points include disease control, duration of objective response, progression-free survival, overall survival, tumor shrinkage, RP2D, and pharmacokinetics. Exploratory biomarker analysis will be performed. This study is being conducted in the United States, Spain, France, South Korea, and Turkey. Enrollment commenced in September 2017, with a target of 50 to 62 patients.

Aim To stablish a consensus on the treatment strategy for advanced non–small-cell lung cancer (aNSCLC) with epidermal growth factor receptor mutation (EGFRm) in Spain. Methods After a systematic literature review, the scientific committee developed 33 statements in 4 fields: molecular diagnosis (10 items); histologic profile and patient clinical characteristics (7 items); first-line (1L) treatment in EGFRm aNSCLC (8 items); and subsequent-line treatment (8 items). A panel of 31 experts completed 2 Delphi online questionnaires rating their degree of agreement/disagreement for each statement through a 1–9 range scale (1–3 = disagree, 7–9 = agree). Consensus was reached if 2/3 of the participants are in the median range. Results In the first Delphi round consensus was achieved for 24/33 of the statements. One of the assertions was deleted, proceeding to a second round with the eight remaining questions with no consensus or in the range of indeterminacy. Determination of the EGFR status from tissue and analysis of the different biomarkers are two important variables that influenced treatment decision in patients with aNSCLC. 1L treatment should be the best therapeutic option, independently of the subsequent lines of treatment. For patients with the most common activating mutations osimertinib was considered the most efficient and safe 1L option. In case of disease progression, a new biopsy was needed. Conclusions A consensus document is proposed to optimize the treatment strategy for untreated patients with a NSCLC with EGFR sensitizing mutations.

Objectives The aim of LungBEAM was to determine the value of a novel epidermal growth factor receptor (EGFR) mutation test in blood based on BEAMing technology to predict disease progression in advanced non‐small cell lung cancer (NSCLC) patients treated with first‐ or second‐generation EGFR‐tyrosine kinase inhibitors (EGFR‐TKIs). Another goal was to monitor the dynamics of EGFR mutations, as well as to track EGFR exon 20 p.T790M (p.T790M) resistance during treatment, as critical indicators of therapeutic efficacy and patient survival. Methods Stage IV NSCLC patients with locally confirmed EGFR‐TKI sensitizing mutations (ex19del and/or L858R) in biopsy tissue who were candidates to receive first‐ or second‐generation EGFR‐TKI as first‐line therapy were included. Plasma samples were obtained at baseline and every 4 weeks during treatment until a progression‐free survival (PFS) event or until study completion (72‐week follow‐up). The mutant allele fraction (MAF) was determined for each identified mutation using BEAMing. Results A total of 68 of the 110 (61.8%) patients experienced a PFS event. Twenty‐six patients (23.6%) presented with an emergent p.T790M mutation in plasma at some point during follow‐up, preceding radiologic progression with a median of 76 (interquartile ratio: 54–111) days. Disease progression correlated with the appearance of p.T790M in plasma with a hazard ratio (HR) of 1.94 (95% confidence interval [CI], 1.48–2.54; p, The manuscript is a multicenter, prospective study conducted in the real‐world setting. The study reveals that the detection and quantification (MAF slope) of EGFR mutations in ctDNA using the highly sensitive BEAMing method may assist in optimizing treatment decisions for advanced NSCLC patients.

Background: Little progress has been achieved in non-small cell lung cancer (NSCLC) patients with unresectable stage III disease and new drug schemes are warranted. Material and methods: In this open-label, single-arm, phase II trial 65 treatment-naive stage III NSCLC deemed surgically unresectable by a multidisciplinary team were treated with 2 cycles of induction cisplatin at 80 mg/m(2) every 21 days plus metronomic oral vinorelbine at 50 mg/day every Monday, Wednesday and Friday. During the concomitant treatment with thoracic radiotherapy cisplatin was administered in the same manner but oral vinorelbine was reduced to 30 mg/day. The objective was to administer a total radiotherapy dose of 66 Gy in 33 daily fractions of 2 Gy. The primary endpoint was progression-free survival (PFS). Correlation between circulating tumor DNA (ctDNA) levels and survival was also evaluated. Results: Fifty-five (78.5 %) patients completed treatment. Overall response rate, by RECIST criteria, was 66.2 %. Four (6.2 %) patients had complete response, 39 (60.0 %) partial response and 12 (18.5 %) stable disease. Seven patients (10.8 %) had progressive disease during the induction period. Median follow-up was 29.1 months (m), median PFS was 11.5 m (95 %CI: 9.6-15.4). PFS at 12 m in the intention-to-treat (ITT) population was 47.8 % (95 %CI: 35.1-59.4 %) and median OS was 35.6 m (95 %CI: 24.4-46.8). Grade >= 3 treatment-related adverse events occurred in 14 (21.5 %) patients during induction and in 13 (24.5 %) patients during concomitant treatment with esophagitis occurring in 3% and pneumonitis in 1.5 % of the patients. Patients with undetectable ctDNA after 3 m follow-up had median PFS and OS of 18.1 m (95 %CI: 8.8-NR) and not reached (NR) (95 %CI: 11.3-NR), respectively, compared with 8.0 m (95 %CI: 2.7-NR) and 24.7 m (95 %CI: 5.7-NR) for patients who remained ctDNA positive at that time point. Conclusions: Metronomic oral vinorelbine and cisplatin obtains similar efficacy results with significantly lower toxicity than the same chemotherapy at standard doses. ctDNA can identify populations with particularly good prognosis.

8512 Background: At the second interim analysis (IA2) of the triple-blind, phase 3 PEARLS/KEYNOTE-091 study (NCT02504372), pembrolizumab significantly improved DFS compared with placebo in patients (pts) with completely resected stage IB (T ≥4 cm) to IIIA NSCLC per AJCC v7, regardless of PD-L1 expression (N = 1177, HR 0.76, 95% CI 0.63-0.91, P = 0.0014). We present DFS in subgroups related to surgery, disease burden, and adjuvant chemotherapy use. Methods: Pts had pathologically confirmed, completely resected stage IB (T ≥4 cm) to IIIA NSCLC of any PD-L1 expression and ECOG PS 0-1. Systematic complete or lobe-specific mediastinal lymph node dissection was recommended; minimally, the subcarinal and 1 lobe-specific lymph node must have been examined. Adjuvant chemotherapy of ≤4 cycles was given as indicated by local guidelines. Eligible pts were randomized 1:1 to pembrolizumab 200 mg or placebo Q3W for 18 doses (̃1 y). Treatment effects on DFS were assessed in prespecified subgroups of with and without adjuvant chemotherapy and in exploratory subgroups defined by surgery type, pN stage, tumor size, no. of adjuvant chemotherapy cycles, and adjuvant regimen; only subgroups of > 50 pts were analyzed. Data cutoff for IA2 was September 20, 2021 (median time from randomization to cutoff, 35.6 mo). Results: By surgery type, the HR (95% CI) for DFS was 0.78 (0.64-0.96) for lobectomy (n = 925), 0.85 (0.43-1.69) for bilobectomy (n = 92), and 0.71 (0.40-1.24) for pneumonectomy (n = 127). For subgroups based on nodal status, HR (95% CI) for DFS was 0.63 (0.46-0.86) for pN0 (n = 490), 0.77 (0.57-1.03) for pN1 (n = 456), and 1.00 (0.71-1.41) for pN2 (n = 231). By tumor size, and irrespective of nodal status, the HR (95% CI) for DFS was 0.91 (0.69-1.20) for size ≤4 cm (n = 491) and 0.70 (0.55-0.89) for size > 4 cm (n = 685). The HR (95% CI) for DFS was 0.73 (0.60-0.89) in pts who received adjuvant chemotherapy (n = 1010) and 1.25 (0.76-2.05) in those who did not (n = 167). Among pts who received adjuvant chemotherapy, HR (95% CI) for DFS by number of cycles was 0.59 (0.28-1.26) for 1-2 (n = 67) and 0.74 (0.61-0.91) for 3-4 (n = 943); by regimen, it was 0.74 (0.55-0.98) for cisplatin + vinorelbine (n = 491), 0.51 (0.31-0.83) for carboplatin + vinorelbine (n = 151), 1.21 (0.73-1.98) for carboplatin + paclitaxel (n = 135), 0.65 (0.30-1.40) for cisplatin + gemcitabine (n = 57), and 0.68 (0.41-1.14) for other regimen (n = 176). Conclusions: Pembrolizumab generally improved DFS versus placebo regardless of type of surgery, lymph node involvement, tumor size, and type and extent of adjuvant chemotherapy in pts with completely resected stage IB (T ≥4 cm) to IIIA NSCLC. These data support the benefit of pembrolizumab as adjuvant therapy for early-stage NSCLC following complete resection and, if indicated, adjuvant chemotherapy. Clinical trial information: NCT02504372.

e24093 Background: Malnutrition is a condition with great impact in oncology patients. Poor nutritional status is often associated with increased morbidity and mortality, increased toxicity and reduced tolerance to chemotherapy, among other complications. The recent GLIM criteria for malnutrition aim to homogenize its diagnosis, considering the baseline disease status. Due to the few studies that assess the predictive capacity of these new criteria, we aimed to evaluate their performance for the prediction of complications and mortality in patients with cancer. Methods: Prospective, single-centre study. All outpatients under active treatment for head and neck, upper gastrointestinal and colorectal tumors between February and October 2020 were recruited. These patients were followed up for 6 months, assessing the occurrence of complications and survival, based on GLIM diagnosis of malnutrition. Results: We enrolled 165 outpatients 46.66% malnutrition. During 6-month follow-up, patients with malnutrition (46.7%, according to GLIM criteria) had an ̃3-fold increased risk of hospital admission (p < 0.001) and the occurrence of severe infections (considered as such those requiring hospitalization, intravenous antibiotics and/or drainage by interventional procedure) during follow-up (p = 0.002). Similarly, malnourished patients had a 3.5-fold increased risk of poor pain control and a 4.4-fold increased need for a higher dose of opioids (both p < 0.001). They also had a 2.6-fold increased risk of toxicity (p = 0.044) and a 2.5-fold increased likelihood of needing a dose decrease or discontinuation of cancer treatment (p = 0.011). 6-month survival of malnourished patients was significantly lower (p = 0.023) than non-malnourished patients. Conclusions: Diagnosis of malnutrition according to GLIM criteria in oncology patients on active treatment predicts increased complications and worse survival at 6-month follow-up, making them a useful tool to assess the nutritional status of oncology patients.[Table: see text]

Background Women represent an increasing proportion of the oncology workforce; however, globally this does not translate into leadership roles, reflecting disparities in career opportunities between men and women. The Spanish Society of Medical Oncology (SEOM) undertook a survey to investigate gender disparity in the Spanish oncology context. Design An online survey was made available to SEOM medical oncologists between February and May 2019. It included demographics, professional context and achievements, parenthood and family conciliation issues, workplace gender bias, and approaches to address disparities. Results Of the 316 eligible respondents, 71.5% were women, 59.5% were aged 45 or younger, and 66.1% had children. Among women, 12.4% were division or unit heads, compared with 45.5% of men, with most women (74.3%) being attending medical oncologists, compared with 45.5% of men. More males were professors (34.4% versus 14.2% of females), had a PhD (46.7% versus 28.8%), and/or had led clinical research groups (41.1% versus 9.7%). Spending time overseas after completing a residency was also more common for men than women (34.4% versus 20.4%). Professional satisfaction was similar between genders, driven primarily by patient care and intellectual stimulation. More women (40.7%) considered parenthood to have a strong negative impact on their career, compared with men (9.0%). Main perceived barriers to gender equality included a lack of work–life balance (72.6% women, 44.4% men), bias of peers and superiors (50.0% women, 18.9% men), and different career goals (41.2% women, 24.4% men). Preferred solutions included educational programs and scholarships (52.9%), communication and leadership training (35.8%), childcare at conferences (33.2%), and postmaternity return-to-work incentives (32.0%). Conclusion There is a clear paucity of equal opportunities for female oncologists in Spain. This can be addressed by encouraging professional development and merit recognition particularly for younger female oncologists, and empowering women to be involved in management and leadership of institutions and professional societies., Highlights • Under-representation of women in leadership roles in oncology is a widely acknowledged issue receiving global attention. • This study is a national description of leadership and educational opportunities in terms of gender and family circumstances. • Perceptions of gender bias in the workplace gender inequality or family conciliation issues and are described. • Initiatives for equal opportunities in oncology are needed supporting female academic career development and recognition.

The advances in molecular biology and the emergence of Next Generation Sequencing (NGS) have revealed that microbiome composition is closely related with health and disease, including cancer. This relationship affects different levels of cancer such as development, progression, and response to treatment including immunotherapy. The efficacy of immune checkpoint inhibitors (ICIs) may be influenced by the concomitant use of antibiotics before, during or shortly after treatment with ICIs. Nevertheless, the linking mechanism between microbiote, host immunity and cancer is not clear and the role of microbiota manipulation and analyses in cancer management has not been clinically validated yet. Regarding the use of microbiome as biomarker to predict ICI efficacy it has been recently shown that the use of biochemical serum markers to monitor intestinal permeability and loss of barrier integrity, like citrulline, could be useful to monitor microbiota changes and predict ICI efficacy. There are still many unknowns about the role of these components, their relationship with the microbiota, with the use of antibiotics and the response to immunotherapy. The next challenge in microbiome research will be to identify individual microbial species that causally affect lung cancer phenotypes and response to ICI and disentangle the underlying mechanisms. Thus, further analyses in patients with lung cancer receiving treatment with ICIs and its correlation with the composition of the microbiota in different organs including the respiratory tract, peripheral blood and intestinal tract could be useful to predict the efficacy of ICIs and its modulation with antibiotic use., JP reported research funding from BMS and Gilead and speaker honoraria from Gilead and Pfizer.

Introduction Uncommon epidermal growth factor receptor (EGFR) mutations (u-EGFRm) are a heterogeneous group of molecular alterations and have also been reported as comutations with other EGFR mutations (complex mutations) in non–small-cell lung cancer (NSCLC). Afatinib has shown activity against some u-EGFRm, and we examined its efficacy in Spanish clinical practice. Patients and Methods Data of 67 patients with advanced NSCLC with u-EGFRm treated with afatinib between 2012 and 2017 at 23 Spanish institutions were reviewed. u-EGFRm were analyzed as complex mutations (group A), EGFR exon 20 insertions (ins20; group B), or single mutations (group C). Efficacy was evaluated in terms of overall survival (OS) and tumor response. Results Group A complex u-EGFRm consisted of double mutations of G719X+E709F, G719X+S768I, G719X+L861Q, L858R+T790M, L858R+S768I, L858R+S765I, del19+S768I, del19+L747S, or R776C+L861Q. No differences in clinical characteristics were found between groups A (n = 20), B (n = 23), and C (n = 24). Afatinib was administered as first-line therapy in 80% of patients. Median time of receipt of therapy was 4.2 months (range, 2.0–12.9 months). Median OS for the entire cohort was 19.9 months (95% confidence interval, 9.7, 30.1). Hazard ratios for OS were 0.26 (95% confidence interval, 0.10, 0.71; P = .008) and 0.40 (95% confidence interval, 0.17, 0.95; P = .037) for groups A and C compared to B, respectively. Response was significantly higher in groups A (70%) and C (54%) compared to B (13%; pairwise comparison P Conclusion In clinical practice, afatinib was active in patients with u-EGFRm NSCLC, particularly in complex and single mutations. Further strategies are needed for patients with ins20, a subgroup u-EGFRm with a lower clinical benefit with afatinib.

20 pags, 5 figs, 7 tabs, Risk population screening programs are instrumental for advancing cancer management and reducing economic costs of therapeutic interventions and the burden of the disease, as well as increasing the survival rate and improving the quality of life for cancer patients. Lung cancer, with high incidence and mortality rates, is not excluded from this situation. The success of screening programs relies on many factors, with some of them being the appropriate definition of the risk population and the implementation of detection techniques with an optimal discrimination power and strong patient adherence. Liquid biopsy based on serum or plasma detection of circulating tumor cells or DNA/RNA is increasingly employed nowadays, but certain limitations constrain its wide application. In this work, we present a new implementation of thermal liquid biopsy (TLB) for lung cancer patients. TLB provides a prediction score based on the ability to detect plasma/serum proteome alterations through calorimetric thermograms that strongly correlates with the presence of lung cancer disease (91% accuracy rate, 90% sensitivity, 92% specificity, diagnostic odds ratio 104). TLB is a quick, minimally-invasive, low-risk technique that can be applied in clinical practice for evidencing lung cancer, and it can be used in screening and monitoring actions., This research was funded by Miguel Servet Program from Instituto de Salud Carlos III (CPII13/00017 to OA); Fondo de Investigaciones Sanitarias from Instituto de Salud Carlos III, and European Union (ERDF/ESF, 'Investing in your future') (PI15/00663 and PI18/00349 to OA, and PI17/01109 to AL); Spanish Ministry of Economy and Competitiveness (BFU2016-78232-P to AVC); Diputación General de Aragón (Protein Targets and Bioactive Compounds Group – E45_17R to AVC, and Digestive Pathology Group – E25_17R to OA and AL); and Centro de Investigación Biomédica en Red en Enfermedades Hepáticas y Digestivas (CIBERehd).

Gent gran; Nivolumab; Càncer de pulmó de cèl·lules no petites Anciano; Nivolumab; Cáncer de pulmón de células no pequeñas Elderly; Nivolumab; Non-small cell lung cancer Background CheckMate 171 (NCT02409368) is an open-label, multicentre, phase 2 trial of nivolumab in previously treated advanced squamous non-small cell lung cancer (NSCLC), conducted as part of a post-approval commitment to the European Medicines Agency (EMA). We report outcomes from this trial. Methods Patients with Eastern Cooperative Oncology Group performance status (ECOG PS) 0–2 and disease progression during/after ≥1 systemic treatment (≥1 being platinum-based chemotherapy) for advanced or metastatic disease were treated with nivolumab 3 mg/kg every 2 weeks until progression or unacceptable toxicity. The primary end-point was incidence of grade 3–4 treatment-related select adverse events (AEs). Other end-points included overall survival (OS) and safety. Results Of 811 patients treated, 103 had ECOG PS 2; 278 were aged ≥70 years and 125 were ≥75 years of age. Minimum follow-up was ~18 months. Safety was similar across populations; the most frequent grade 3–4 treatment-related select AEs in all treated patients were diarrhoea (1%), increased alanine aminotransferase (ALT, 1%), pneumonitis (0.7%), colitis (0.6%) and increased aspartate aminotransferase (AST, 0.5%). Median OS was similar in all treated patients and those aged ≥70 and ≥75: 10.0 months, 10.0 months and 11.2 months, respectively. Median OS was 5.2 months in patients with ECOG PS 2. Conclusion These results suggest that nivolumab is well tolerated and active in patients with advanced, relapsed squamous NSCLC, including the elderly, with OS outcomes consistent with phase 3 data. In patients with ECOG PS 2, nivolumab had similar tolerability, but outcomes were worse, as expected in this difficult-to-treat, poor prognosis population. Funded by Bristol-Myers Squibb.

[Objectives] Resistance to tyrosine-kinase inhibitors (TKIs) is a clinical challenge in patients with oncogene-driven non-small-cell lung cancers (NSCLC). We have analyzed the utility of next-generation sequencing (NGS) of cell-free circulating tumor DNA (ctDNA) to impact the clinical care of patients with TKI resistance., [Materials and methods] We conducted a multi-institutional prospective study including consecutive EGFR, ALK, or ROS1-altered NSCLC patients with TKI resistance from 12 Spanish institutions. Post-progression ctDNA NGS was performed by Guardant Health (Guardant360 assay)., [Results] We included 53 patients separated in 3 cohorts: 31 EGFR-mutant NSCLCs with first/second-generation TKI resistance (cohort 1), 15 EGFR T790M + NSCLCs with osimertinib resistance (cohort 2), and 7 ALK/ROS1-rearranged NSCLCs with crizotinib and/or next-generation TKI resistance (cohort 3). Besides Guardant360, 22 patients from cohort 1 (71%) underwent post-progression tumor biopsies and/or alternative plasma-based genotyping. In the entire study population, 34 patients (64%) had reliable evidence of tumor-DNA shed for resistance assessment, and 24 patients (45%) had actionable alterations. Target-independent pathogenic alterations were frequently detected, particularly at osimertinib resistance. Eleven patients (20%) received subsequent molecular-guided therapies indicated by plasma NGS alone (n = 9, 17%), or plasma NGS and tissue sequencing (n = 2, 4%), deriving the expected clinical benefit. Of these, 9 had EGFR T790 M mutation and received osimertinib, 1 had ALK G1202R mutation and received lorlatinib, and 1 had ROS1 G2032R mutation and received cabozantinib. Two additional cases from cohort 1 (6%) had undetectable EGFR T790 M by Guardant360 but were T790M + by tissue and BEAMing digital PCR respectively, and also received osimertinib., [Conclusion] NGS of ctDNA detects actionable alterations in a large proportion of oncogene-driven NSCLC patients with TKI resistance, and can be used to guide subsequent treatments as a complement or alternative to tissue or PCR-based plasma genotyping in the real-world clinical setting., J.

In 2011 the Spanish Society of Medical Oncology (SEOM) and the Spanish Society of Pathology (SEAP) started a joint project to establish guidelines on biomarker testing in patients with advanced non-small-cell lung cancer (NSCLC) based on current evidence. As this field is constantly evolving, these guidelines have been updated, previously in 2012 and 2015 and now in 2019. Current evidence suggests that the mandatory tests to conduct in all patients with advanced NSCLC are for EGFR and BRAF mutations, ALK and ROS1 rearrangements and PD-L1 expression. The growing need to study other emerging biomarkers has promoted the routine use of massive sequencing (next-generation sequencing, NGS). The coordination of every professional involved and the prioritisation of the most suitable tests and technologies for each case remains a challenge., SEAP and SEOM have received financial support for this project in the form of unrestricted grants from AstraZeneca, Novartis, Pfizer, Roche, Sysmex and Takeda.

Purpose: Immunotherapy-based approaches are standard first-line treatments for advanced/metastatic lung cancer or for chemoradiotherapy consolidation in locally advanced disease. Uncertainty on how to treat patients at disease progression prompted us to develop a consensus document on post-immunotherapy options in Spain for patients with advanced wild-type lung adenocarcinoma. Methods: After extensive literature review, a 5-member scientific committee generated 33 statements in 4 domains: general aspects (n = 4); post-durvalumab in locally advanced disease (n = 6); post-first-line immunotherapy ± chemotherapy in advanced/metastatic disease (n = 11); and post-first-line platinum-based chemotherapy in advanced/metastatic disease (n = 12). A panel of 26 lung cancer experts completed 2 Delphi iterations through an online platform rating their degree of agreement/disagreement (first-round scale 1–5 and second-round scale 1–4, 1 = strongly disagree, 4/5 = strongly agree) for each statement. Second-round consensus: ≥ 70% of responses were in categories 1/2 (disagreement) or 3/4 (agreement). Results: Consensus was reached for 2/33 statements in the first Delphi round and in 29/31 statements in the second round. Important variables informing treatment at disease progression with an immunotherapy-based treatment include: disease aggressiveness, previous treatment, accumulated toxicity, progression-free interval, PD-L1 expression, and tumour mutational burden. A platinum-based chemotherapy should follow a first-line immunotherapy treatment without chemotherapy. Treatment with docetaxel + nintedanib may be appropriate post-durvalumab in refractory patients or following progression to first-line chemotherapy + immunotherapy, or second-line chemotherapy after first-line immunotherapy, or first-line chemotherapy in some patients with low/negative PD-L1 expression, or second-line immunotherapy after first-line chemotherapy. Conclusions: To support decision making following progression to immunotherapy-based treatment in patients with advanced wild-type lung adenocarcinoma, a consensus document has been developed., The project was funded by Boehringer Ingelheim.

Objectives: Concomitant chemo-radiation is the standard treatment for unresectable stage III non-small cell lung cancer (LA-NSCLC), The aim of this study was to assess the safety and efficacy of oral vinorelbine and cisplatin (OVP) compared with etoposide and cisplatin (EP), both in combination with radiotherapy, in this setting. Material and methods: An open-label, randomized phase II trial was undertaken including 23 hospitals in Spain. Adults with untreated unresectable stage III NSCLC were randomizedl:1 to receive: oral vinorelbine (days 1 and 8 with cisplatin on day 1 in 3-week cycles; 2 cycles of induction, 2 cycles in concomitance) or etoposide (days 1-5 and 29-32 with cisplatin on days 1 and 8 in 4-week cycles; 2 cycles in concomitance). Both groups received concomitant radiotherapy 2 Gy/day (66 Gy). The primary endpoint was progression free survival (PFS). Results: One hundred and forty patients were enrolled. Sixty-nine patients received OVP and 71 received EP. Globally adverse events grade 3/4 per cycle were fewer in the vinorelbine arm (19.4%) than in the etoposide arm (62.6%) (p < 0.001). One patient (1.5%) in the OVP arm and 12 pts (17.6%) in the EP arm presented esophagitis grade 3/4 (p = 0.002). Median PFS was similar in both groups (10.8 [95% CI 7.7-13.8] and 9.6 months [95% CI 4.4-14.8]; p = 0.457, respectively). Preliminary median overall survival was 30 months in the OVP arm and 31.9 months in the EP arm (p = 0.688). Conclusions: Our findings show that OVP could be considered a standard combination with similar efficacy and better safety profile for the treatment of LA-NSCLC patients.

e24065 Background: Malnutrition is one of the most prevalent problems among oncological patients. It reduces the response to treatments and negatively impacts survival. In 2019, a consensus criteria for diagnosing malnutrition (GLIM criteria) were proposed by most scientific nutrition societies. The objective of our work is 1) to assess the diagnostic capacity of the GLIM criteria in ambulatory patients with cancer and 2) to compare the GLIM with the ESPEN criteria to evaluate the contributions of these new criteria with respect to the existing ones. Methods: Observational, cross-sectional, and single-center study carried out at the Medical Oncology Department in the Lozano Blesa Clinical Hospital in Zaragoza (Spain). One hundred and sixty-five outpatients with tumors in the upper gastrointestinal tract, head and neck, and colorectal locations were recruited. All of them received the MST, MUST, and Nutriscore screening tools along with the ESPEN and GLIM diagnostic criteria. Results: The prevalence of malnutrition was 46.7% according to the GLIM criteria and 21.2% using the ESPEN tool. Patients diagnosed by GLIM had a higher body mass index (BMI, 24.3 kg/m2) and muscle mass (MM, 16.1 kg/m2) than those diagnosed by ESPEN (21.2 kg/m² and 14.3 kg/m2 respectively, both p = 0.001). The MST, MUST, and Nutriscore tools had a higher degree of concordance with GLIM compared to ESPEN (MST 0.53 vs 0.26; MUST 0.36 vs 0.66; Nutriscore 0.28 vs 0.54). Conclusions: The found prevalence of malnutrition in cancer patients is higher using the GLIM instead of ESPEN criteria. This disparity can be explained at least in part by the difficulty of the ESPEN criteria for malnutrition to diagnose patients with high baseline BMI or MM. The use of criteria with greater sensitivity, such as the new GLIM criteria, could help early diagnosis and thus early intervention in cancer patients. [Table: see text]

9076 Background: PD-L1 has emerged as a potential biomarker for predicting responses to immunotherapy and as a prognostic factor in non-small cell lung cancer (NSCLC). In this network meta-analysis, we aimed to evaluate the efficacy of first-line PD-(L)1 monotherapy in advanced NSCLC patients with high PD-L1 expression. Methods: We conducted a systematic search in PubMed to identify all eligible trials from inception until 1 November 2020, with no start date limit applied. Only phase III trials evaluating the efficacy of first-line (1L) PD-(L)1 monotherapy in patients with stage IIIB/stage IV NSCLC and high PD-L1 expression were included. Results: Six clinical trials (KEYNOTE-024, KEYNOTE-042, EMPOWER Lung-01, IMpower110, MYSTIC and CheckMate-026) with 2,111 patients were included. In head-to-head comparisons, immunotherapy showed a significant improvement in progression-free survival (PFS: HRpooled = 0.69, 95% CI: 0.52-0.90, p = 0.007), overall survival (OS: HRpooled = 0.69, 95% CI: 0.61-0.78; p < 0.001) and overall response rate (ORR) (Risk ratio [RR]pooled = 1.354, 95% CI: 1.04-1.762, p = 0.024) compared to chemotherapy (CT). In the assessment of relative efficacy for PFS through indirect comparisons, pembrolizumab (results from KEYNOTE-024) ranked highest followed by cemiplimab and atezolizumab, with statistical significance determined across some of the drugs. In terms of OS, cemiplimab ranked highest followed by atezolizumab and pembrolizumab, although non-significant OS was determined across these drugs. Overall, 1L PD-(L)1 monotherapy improved OS in almost all subgroups, reaching statistical significance in men (HRpooled = 0.624, 95% CI: 0.51-0.72, p < 0.001), non-Asian patients (HRpooled = 0.66, 95% CI: 0.55-0.79, p < 0.001), all patients regardless of age ( < 65 years [HRpooled = 0.72, 95% CI: 0.57-0.90, p = 0.005]; ≥65 years [HRpooled = 0.61, 95% CI: 0.48-0.77, p < 0.001]), ECOG PS status (ECOG PS = 0 [HRpooled = 0.68, 95% CI: 0.56-0.82, p < 0.001; ECOG PS = 1 [HRpooled = 0.59, 95% CI: 0.43-0.82, p = 0.001) and histological tumour type (Squamous [HRpooled = 0.49, 95% CI: 0.37-0.67, p < 0.001; Non-squamous [HRpooled = 0.67, 95% CI: 0.52-0.87, p = 0.003). In the case of smokers and NSCLC stage, only current/former smokers (HRpooled = 0.623, 95% CI: 0.47-0.83, p = 0.001) and patients with stage IV disease* (HRpooled = 0.687, 95% CI: 0.59-0.81, p < 0.001) benefited from single PD-(L)1 monotherapy over CT. Conclusions: PD-(L)1 inhibitor monotherapy improves efficacy outcomes in the 1L setting of advanced NSCLC patients with high PD-L1 expression. Current/former smokers ≥65 years, with ECOG PS = 1 and squamous NSCLC benefited most from this therapy. *KEYNOTE-042 was the only study including patients with stage IIIB NSCLC.

e22502 Background: Inherited mutations in the CHEK2 gene have been associated with an increased lifetimerisk of develop breast cancer (BC). The main objective of the study is to identify in our population the prevalence of mutations in the CHEK2 gene in diagnosed BC patients, as well as to evaluate the phenotypic characteristics of the tumour and family history. Methods: A genetic study was performed in 396 patients diagnosed of BC at the University Hospital Lozano Blesa of Zaragoza (Spain). We selected 9 patients with genetic variants in the CHEK2 gene and performed a descriptive analysis of the clinical variables, a bibliographic review of the genetic variants and a co-segregation study. Results: We identified 2 pathogenic variants ( CHEK2 c.349 A>G and c.507delT) and 6 variants of uncertain significance (VUS). The genotypic characteristics of the VUS are summarized in the table. In all cases there was a family history of BC in first and /or second degree relatives. The variant cosegregated with the disease in one of the families. Conclusions: The pathogenic missense variant c.349A>G was found in two families. This is a rare missense variant. Studies have shown that this variant had a significant impact on the protein based on in silico prediction and has been associated with BC. In our study, this variant was found in a patient with renal carcinoma and was identified in a proband with a strong family history of pancreatic and ovarian cancer (OC). However, there aren’t exist data about the risk of developing other cancer, different of BC, with this specific mutation. The other pathogenic variant detected was CHEK2 c.507delT in a family with history of BC and OC. This variant is a frameshift mutation, predicted to cause loss of normal protein function. CHEK2 507delT was reported in one of 12 BC families in one series and is possible its relation with OC. With regard to the VUS the cosegregation analysis in selected families may help understand if a variant could have played a role in developing cancer. In conclusion, CHEK2 mutations have been associated with increased risk for BC. However, the frequency of carriers may vary depending on the population, and different mutations may be associated with different cancer risks. More studies are needed to establish a complete range of risks associated with CHEK2 mutations. [Table: see text]

e21052 Background: Immunotherapy is proposed as a therapeutic novelty in metastatic non-small cell lung cancer (NSCLC), in many cases already in front line. It presents different adverse effects than traditional schemes, due to the stimulation of the immune system. There is a possible relationship between toxicity and response. Neutrophil-to-lymphocyte ratio (NLR) as a possible predictive factor of response. Objectives: Evaluating the response according to the toxicity degree in NSCLC patients in real clinical practice. Analyze whether pretreatment NLR high patients have a worse prognosis. Methods: Observational, retrospective, analytical, single-center study. HCULB stage IV NSCLC patients with inmunotherapy treatment during 2016-2018. Descriptive and multivariate analysis. Toxicity grade: CTCAE version 4.0. Response assessment: RECIST 2.0 and immunorelated criteria. Toxicity degree and response (global and individualized results according to treatment and histology). Neutrophil-to-lymphocyte ratio and response. Results: N = 43 patients (35 men, 8 women). Average age 64 years. Response: 3 complete response (CR) (toxicity ≥2), 13 partial response (PR) (toxicity ≥1), 13 stable disease (SD), 12 progression (P) (only 4 toxicity and ≤2), 2 not evaluated. Hypothyroidism as the most common irAE. Relationship between toxicity and response: the absence of irAEs conditions worse prognosis p < 0.05. Histology: 25 adenocarcinoma [18 with irAES (1 CR, 7 PR, 8 SD,) and 7 without (1 SD, 5 P, 1 no ev.)]; 17 squamous [13 with irAES (1 CR, 6 PR, 4 SD) and 4 without (3 P, 1 no ev.)]; 1 adenosquamous with irAES and CR. Drug: Atezolizumab N = 8 [6 with irAES (2 PR, 3 SD, 1 P) and 2 without (both P)], Nivolumab N = 16 [9 with irAES (1 CR, 3 PR, 3 SD, 2 P) and 7 without (1 SD, 4 P, 2 no ev.)], Pembrolizumab N = 19 [17 with irAEs (2 CR, 8 PR, 6 SD, 1 P) and 2 without (both P)]. Significant positive correlation between toxicity and response (p < 0.001) R = 0.067, (CI 99% 0.378-0.837), regardless of histology and drug. It is observed a better response in those patients who presented a NRL close to 3 or less at the beginning of treatment. On the contrary, it is observed that subjects with NRL greater than 4 obtained worse results when they were treated with immunotherapy. Conclusions: The appearance of irAES like a response indicator of immune system, seem to conditione better evolution. In contrast, the absence of toxicity predicts a worse prognosis. Further studies with a larger sample are needed to confirm our findings about the predictive value of NLR and optimize therapeutic regimens if necessary.

Bone metastases are common in many advanced solid tumours, being breast, prostate, thyroid, lung, and renal cancer the most prevalent. Bone metastases can produce skeletal-related events (SREs), defined as pathological fracture, spinal cord compression, need of bone irradiation or need of bone surgery, and hypercalcaemia. Patients with bone metastases experience pain, functional impairment and have a negative impact on their quality of life. Several imaging techniques are available for diagnosis of this disease. Bone-targeted therapies include zoledronic acid, a potent biphosfonate, and denosumab, an anti-RANKL monoclonal antibody. Both reduce the risk and/or delay the development of SREs in several types of tumours. Radium 233, an alpha-particle emitter, increases overall survival in patients with bone metastases from resistant castration prostate cancer. Multidisciplinary approach is essential and bone surgery and radiotherapy should be integrated in the treatment of bone metastases when necessary. This SEOM Guideline reviews bone metastases pathogenesis, clinical presentations, lab tests, imaging techniques for diagnosis and response assessment, bone-targeted agents, and local therapies, as radiation and surgery, and establishes recommendations for the management of patients with metastases to bone.

2 tables., Immune control inhibitor drugs (anti-PD1/PD-L1/CTLA-4) (ICIs) are showing efficacy in the treatment of lung cancer. Currently the only biomarker with clinical utility for ICIs, such as the expression of PDL1, does not appear to be perfect or effective. Our working group is conducting a pilot study in lung cancer patients receiving ICIs with the aim of analyze the factors that affect the sensitivity of the immunotherapy in lung Cancer. Tumor Mutational Burden (TMB) and the sequencing of the T Cell Receptor (TCR) repertoire in peripheral blood have been postulated as predictive biomarkers of efficacy of immunotherapy. The review focusses on the predictive value of TMB for clinical responses to ICIs and discusses its clinical need after a discussion of the limitations. TCR CDR3 beta analysis and parameters such as clonality and TCR convergence may be good alternatives. For the moment, the combination of biomarkers may be the optimal tool., Despite therapeutic advances, lung cancer (LC) is one of the leading causes of cancer morbidity and mortality worldwide. Recently, the treatment of advanced LC has experienced important changes in survival benefit due to immune checkpoint inhibitors (ICIs). However, overall response rates (ORR) remain low in unselected patients and a large proportion of patients undergo disease progression in the first weeks of treatment. Therefore, there is a need of biomarkers to identify patients who will benefit from ICIs. The programmed cell death ligand 1 (PD-L1) expression has been the first biomarker developed. However, its use as a robust predictive biomarker has been limited due to the variability of techniques used, with different antibodies and thresholds. In this context, tumor mutational burden (TMB) has emerged as an additional powerful biomarker based on the observation of successful response to ICIs in solid tumors with high TMB. TMB can be defined as the total number of nonsynonymous mutations per DNA megabases being a mechanism generating neoantigens conditioning the tumor immunogenicity and response to ICIs. However, the latest data provide conflicting results regarding its role as a biomarker. Moreover, considering the results of the recent data, the use of peripheral blood T cell receptor (TCR) repertoire could be a new predictive biomarker. This review summarises recent findings describing the clinical utility of TMB and TCRβ (TCRB) and concludes that immune, neontigen, and checkpoint targeted variables are required in combination for accurately identifying patients who most likely will benefit of ICIs.

This article belongs to the Special Issue Cancer Immunology: From Molecular Mechanisms to Therapeutic Opportunities., The molecular and cell determinants that modulate immune checkpoint (ICI) efficacy in lung cancer are still not well understood. However, there is a necessity to select those patients that will most benefit from these new treatments. Recent studies suggest the presence and/or the relative balance of specific lymphoid cells in the tumor microenvironment (TEM) including the T cell (activated, memory, and regulatory) and NK cell (CD56dim/bright) subsets, and correlate with a better response to ICI. The analyses of these cell subsets in peripheral blood, as a more accessible and homogeneous sample, might facilitate clinical decisions concerning fast prediction of ICI efficacy. Despite recent studies suggesting that lymphoid circulating cells might correlate with ICI efficacy and toxicity, more analyses and investigation are required to confirm if circulating lymphoid cells are a relevant picture of the lung TME and could be instrumental as ICI response biomarkers.

e21623 Background: IMpower110 evaluated atezo mono in PD-L1–selected, chemo-naive patients (pts) with nonsquamous (nsq) or squamous (sq) NSCLC. At the interim analysis, IMpower110 met its primary OS endpoint, with a statistically significant and clinically meaningful improvement for atezo vs chemo in TC3 or IC3 wild-type ( EGFR/ALK-negative) pts. We report on the safety profile of atezo vs chemo in IMpower110. Methods: 572 pts with stage IV nsq or sq NSCLC, PD-L1 expression ≥ 1% on TC or IC and ECOG PS 0-1 were randomized 1:1 to receive atezo (1200 mg IV q3w) or chemo (4 or 6 21-day cycles). In the chemo arm, nsq pts received cisplatin (cis) 75 mg/m2 or carboplatin (carbo) AUC 6 + pemetrexed (pem) 500 mg/m2 IV q3w; sq pts received cis 75 mg/m2 + gemcitabine (gem) 1250 mg/m2 or carbo AUC 5 + gem 1000 mg/m2 IV q3w. Safety was assessed in all treated pts (safety evaluable [SE] population [pop]), regardless of PD-L1 expression or EGFR/ALK status. AEs were summarized per MedDRA v22.0 and severity graded per NCI CTCAE v4.0. Immune-mediated AEs (imAEs) were defined per a sponsor-specified list of terms, regardless of whether the events led to systemic glucocorticoid, endocrine therapy, or other immunosuppressants use. Results: At data cutoff (Sep 10, 2018) within the ITT pop, treatment (tx) was ongoing in 90 (atezo: 31.6%) and 25 (chemo: 8.7%) pts, with 13.7 mo of follow-up. Within the SE pop (atezo: n = 286, chemo: n = 263), atezo pts had longer tx exposure (5.3 mo) vs chemo pts (pem, 3.5 mo; gem, 2.6 mo; carbo, 2.3 mo; cis, 2.1 mo). Atezo had a favorable safety profile vs chemo (table); safety data were consistent with data from a pooled atezo mono pop. imAEs occurred in 40.2% (atezo) and 16.7% (chemo) of pts and were Grade (Gr) 3-4 in 6.6% and 1.5%, respectively. Conclusions: Atezo was better tolerated than chemo and imAEs were generally low grade. Overall, the safety experience with atezo mono in IMpower110 was consistent with its known safety profile; no new safety signals were identified. Clinical trial information: NCT02409342.

Purpose: HER2-targeted therapy is not standard of care for HER2-positive non–small cell lung cancer (NSCLC). This phase II study investigated efficacy and safety of the HER2-targeted antibody–drug conjugate trastuzumab emtansine (T-DM1) in patients with previously treated advanced HER2-overexpressing NSCLC. Patients and Methods: Eligible patients had HER2-overexpressing NSCLC (centrally tested IHC) and received previous platinum-based chemotherapy and targeted therapy in the case of EGFR mutation or ALK gene rearrangement. Patients were divided into cohorts based on HER2 IHC (2+, 3+). All patients received T-DM1 3.6 mg/kg intravenously every 3 weeks until disease progression or unacceptable toxicity. The primary endpoint was investigator-determined overall response rate (ORR) using RECIST v1.1. Results: Forty-nine patients received T-DM1 (29 IHC 2+, 20 IHC 3+). No treatment responses were observed in the IHC 2+ cohort. Four partial responses were observed in the IHC 3+ cohort (ORR, 20%; 95% confidence interval, 5.7%–43.7%). Clinical benefit rates were 7% and 30% in the IHC 2+ and 3+ cohorts, respectively. Response duration for the responders was 2.9, 7.3, 8.3, and 10.8 months. Median progression-free survival and overall survival were similar between cohorts. Three of 4 responders had HER2 gene amplification. No new safety signals were observed. Conclusions: T-DM1 showed a signal of activity in patients with HER2-overexpressing (IHC 3+) advanced NSCLC. Additional investigation into HER2 pathway alterations is needed to refine the target population for T-DM1 in NSCLC; however, HER2 IHC as a single parameter was an insufficient predictive biomarker.

Background: Although the benefit of first-line epidermal growth factor receptor (EGFR) tyrosine-kinase inhibitors (TKIs) over chemotherapy has been demonstrated in several clinical trials, data from clinical practice is lacking and the optimal EGFR TKI to be used remains unclear. This study aims to assess the real-life diagnostic and clinical management and outcome of patients with advanced non-small-cell lung cancer (NSCLC) carrying EGFR mutations in Spain. Methods: All consecutive patients recently diagnosed with advanced or metastatic NSCLC from April 2010 to December 2011 in 18 Spanish hospitals and carrying EGFR mutations were retrospectively evaluated. Results: Between March and November 2013, a total of 187 patients were enrolled (98.3% Caucasian, 61.9% female, 54.9% never-smokers, 89.0% adenocarcinoma). Mutation testing was mainly performed on biopsy tumour tissue specimens (69.0%) using a qPCR-based test (90%) (47.0% Therascreen EGFR PCR Kit). Common sensitising mutations were detected in 79.8% of patients: 57.1% had exon 19 deletions and 22.6% exon 21 L858R point mutations. The vast majority of patients received first-line therapy (n = 168; 92.8%). EGFR TKIs were the most commonly used first-line treatment (81.5%), while chemotherapy was more frequently administered as a second-and third-line option (51.9% and 56.0%, respectively). Of 141 patients who experienced disease progression, 79 (56.0%) received second-line treatment. After disease progression on first-line TKIs (n = 112), 33.9% received chemotherapy, 8.9% chemotherapy and a TKI, and 9.8% continued TKI therapy. Most patients received first-line gefitinib (83.0%), while erlotinib was more frequently used in the second-line setting (83.0%). Progression-free survival (PFS) and overall survival (OS) in patients harbouring common mutations were 11.1 months and 20.1 months respectively (exon 19 deletions: 12.4 and 21.4 months; L858R: 8.3 and 14.5 months), and 3.9 months and 11.1 months respectively for those with rare mutations. Conclusion: EGFR TKIs (gefitinib and erlotinib) are used as the preferred first-line treatment while chemotherapy is more frequently administered as a second-and third-line option in routine clinical practice in Spain. In addition, efficacy data obtained in the real-life setting seem to concur with data from EGFR TKI phase III pivotal studies in NSCLC.

WOS: 000444765300010, PubMed ID: 29902295, IMPORTANCE Treatment choice for lung squamous cell carcinoma could be aided by identifying predictive biomarkers. OBJECTIVE To assess whether patient outcomes in the LUX-Lung 8 trial were associated with ERBB gene family member aberrations in tumor specimens. DESIGN, SETTING, AND PARTICIPANTS Ad hoc secondary analysis of the LUX-Lung 8 trial conducted at 183 centers in 23 countries from March 30, 2012, to January 30, 2014. Eligible patients had stage IIIB or IV lung squamous cell carcinoma with progressive disease after 4 or more cycles of platinum-based chemotherapy. Tumor genetic analysis (TGA) was performed using next-generation sequencing in a cohort enriched for patients with progression-free survival (PFS) of more than 2 months. Epidermal growth factor receptor (EGFR) expression levels were assessed by immunohistochemistry in a separate cohort of patients from the LUX-Lung 8 population. Associations of PFS and overall survival (OS) with ERBB gene alterations and EGFR expression levels were assessed. This analysis was conducted from February 26, 2015, to June 12, 2017. INTERVENTIONS Patients were randomized 1:1 to treatment with afatinib dimaleate (40mg/d; n = 398) or erlotinib hydrochloride (150mg/d; n = 397). MAIN OUTCOMES AND MEASURES Overall survival, PFS, pooled and individual ERBB gene mutations, ERBB copy number alterations, and EGFR expression. RESULTS Tumor specimens from 245 patients were eligible for next-generation sequencing (TGA subset: 132 patients treated with afatinib; 113 patients treated with erlotinib). In this population, outcomes were improved with afatinib vs erlotinib treatment (PFS: median, 3.5 vs 2.5 months; hazard ratio [HR], 0.69; 95% CI, 0.51-0.92; P = .01; OS: median, 8.4 vs 6.6 months; HR, 0.81; 95% CI, 0.62-1.05; P = .12). Of 245 patients in the TGA subset, 53 (21.6%) had tumors with 1 or more ERBB mutations. Among afatinib-treated patients, PFS (median, 4.9 vs 3.0 months; HR, 0.62; 95% CI, 0.37-1.02; P = .06) and OS (median, 10.6 vs 8.1 months; HR, 0.75; 95% CI, 0.47-1.17; P = .21) were longer among those with ERBB mutation-positive disease than among those without. The presence of HER2 mutations was associated with favorable PFS and OS following afatinib vs erlotinib treatment. There was no apparent association between copy number alteration or EGFR expression level and outcome. CONCLUSIONS AND RELEVANCE Next-generation sequencingmay help identify patients with lung squamous cell carcinoma who would derive additional benefit from treatment with afatinib. The role of ERBB mutations, particularly HER2 mutations, as predictive biomarkers for afatinib treatment in this setting warrants further evaluation., Boehringer IngelheimBoehringer Ingelheim, This study was funded by Boehringer Ingelheim.

WOS: 000405152800017, PubMed ID: 28577938, Objectives: Identification of biomarkers associated with clinical benefit may be crucial in establishing optimal treatment choice for patients with squamous cell carcinoma (SCC) of the lung after first-line chemotherapy. In this study, the ability of the VeriStrat serum protein test to predict differential clinical benefit with afatinib versus erlotinib, and the association of VeriStrat status with clinical outcomes irrespective of EGFR-TKI used, was assessed in a retrospective analysis of the phase III LUX-Lung 8 trial. Materials and methods: Pretreatment plasma samples were analyzed using matrix-assisted laser desorption ionization time-of-flight mass spectrometry. Spectra were evaluated to assign a VeriStrat 'Good' (VS-G) or VeriStrat 'Poor' (VS-P) classification. Overall survival (OS), progression-free survival, and other endpoints were assessed with respect to pretreatment VeriStrat status; OS was the primary efficacy variable. Results: Of 795 patients randomized in LUX-Lung 8, 675 were classified (VS-G: 412; VS-P: 263). In the VS-G group, OS was significantly longer with afatinib versus erlotinib (HR 0.79 [95% CI: 0.63-0.98]). In the VS -P group, there was no significant difference in OS between afatinib and erlotinib (HR 0.90 [0.70-1.16]). However, there was no interaction between VeriStrat classification and treatment group for OS la interaction = 0.5303). OS was significantly longer in VS-G versus VS -P patients, both in the overall VeriStrat-classified population (HR 0.41 [0.35-0.49]) and afatinib-treated patients (HR 0.40 [0.31-0.51]). Multivariate analysis showed that VeriStrat was an independent predictor of OS in afatinib-treated patients, regardless of ECOG PS or best response to first line chemotherapy. Outcomes with other efficacy endpoints were similar. Conclusion: VS-G classification is strongly associated with favorable survival outcomes with either afatinib or erlotinib compared with VS-P classification. In VS-G patients, survival outcomes with afatinib are superior to those with erlotinib. VeriStrat classification may guide treatment decisions in patients with SCC of the lung., Boehringer IngelheimBoehringer Ingelheim, This study was funded by Boehringer Ingelheim.

The WORLD07 study characterizes lung cancer in Spanish women. This analysis investigated lung cancer features in never-smoking women. Of 2072 women recruited, 2035 were analyzed. Patient characteristics and demographics were similar for current/former smokers and never smokers. Among never smokers, 38.3% were exposed to passive smoking. Non-small-cell lung cancer was the most common type (78.8% of current/former smokers and 96.1% of never smokers) and adenocarcinoma the most common histology (69.1% and 83.4% respectively). There was a high incidence of lung cancer in Spanish never-smoking women and a high proportion (about 50%) had mutant epidermal growth factor receptor.

[Background/Aim] First-line bevacizumab-based therapies have been shown to improve clinical outcomes in patients with non-squamous non-small-cell lung cancer (NSCLC). We aimed to descriptively analyse patients with non-squamous NSCLC who received a long-term period of maintenance bevacizumab., [Patients and methods] This retrospective study included 104 patients who had already reached a progression-free survival (PFS) of at least 9 months., [Results] Median overall survival and PFS were 30.7 and 15.1 months, respectively. The overall response rate was 83 %. Weight loss ≤5 %, ECOG PS = 0, or low number of metastatic sites seem to be predictive factors of good evolution. The incidence of bevacizumab-related adverse events appeared to be similar as the previous studies., [Conclusion] Our findings show that there is a long-term survivor group whom the administration of bevacizumab resulted in a relevant prolongation of response without new safety signals. Due to the population heterogeneity, it was not possible to identify the standardised predictive factors., This work was supported by Roche Farma, S.A., Spain.

Objectives Dysregulation of the downstream PI3K/AKT/mTOR signaling pathway is a proposed mechanism of resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). We investigated safety and antitumor activity of afatinib plus sirolimus as a potential combination to reverse acquired resistance to EGFR-TKIs in a phase IB trial in patients with EGFR mutation-positive non-small-cell lung cancer ( EGFR mut NSCLC) and/or disease progression following prior erlotinib/gefitinib. Materials and methods Patients with EGFR mut NSCLC and/or disease progression following at least prior erlotinib/gefitinib were included in the trial. The primary endpoint was incidence of dose-limiting toxicities (DLT) to determine the maximum tolerated dose (MTD). Four initial dose cohorts were proposed to evaluate DLTs. Other endpoints included tumor response, safety, progression-free survival (PFS) and pharmacokinetics. Results Thirty-nine patients received afatinib and sirolimus. Additional dose cohorts were added since the second cohort (afatinib 40 mg/day and sirolimus 5 mg/day) was considered to have excessive toxicity. All patients experienced adverse events (AE) [grade 3: 66.7%; serious AE: 56.4%]. The most frequent AEs were diarrhea (94.9%), mucosal inflammation (64.1%), asthenia (53.8%) and rash (53.8%). Discontinuations and dose reduction due to AEs occurred in 23.1% and 25.6% of patients. MTD was determined as afatinib 30 mg and sirolimus 1 mg. Responses were observed in 5 patients (12.8%) [2 (5.1%) with confirmed partial response (PR); 3 (7.7%) with unconfirmed PR], and stable disease in 18 patients (46.2%). Four of the 5 responses were at doses above MTD. PFS at 6 months was estimated in 33.3% (median PFS 3.4 months). Pharmacokinetic parameters of afatinib and sirolimus were similar after single administration or in combination. Conclusion The combination of afatinib and sirolimus showed lower responses than expected. Together with increased AEs and poor tolerability, this precludes clinical use and further clinical development of this combination. No pharmacokinetic interactions were observed.

The WORLD07 project is a female specific database to assess the characteristics of women with lung cancer. WORLD07 database sets up in 2007, and prospectively stores clinical characteristics, treatment, outcome, and follow-up of lung cancer women. All women with epidermal growth factor receptor (EGFR) mutation non-small cell lung cancer (NSCLC) were selected for this analysis. From October 2007 to December 2012, a total of 1775 NSCLC women were recruited. EGFR mutation was identified in 34.4% of patients. Upfront EGFR tyrosine kinase inhibitor (TKI) reported a response rate of 60%, a median progression-free survival of 11.7 months, and median overall survival of 23.0 months. EGFR TKI, EGFR-mutation type, and smoking status did not impact in the outcome of treated women. Prevalence of EGFR mutation in women with NSCLC is higher than overall population with NSCLC. Efficacy of EGFR TKI in this real-world setting is similar to that previously reported.

In 2011, the Spanish Society of Medical Oncology and the Spanish Society of Pathology started a joint project to establish recommendations on biomarker testing in patients with advanced non-small-cell lung cancer based on the current evidence. Most of these recommendations are still valid, but new evidence requires some aspects to be updated. Specifically, the recommendation about which biomarkers to test in which patients is being amended, and the best way to manage tumour samples and minimum requirements for biomarker test material are defined. Suitable techniques for testing for epidermal growth factor receptor mutations and anaplastic lymphoma kinase rearrangement are also reviewed, and a consensus is reached on which situations warrant re-biopsy.

Lung cancer incidence is decreasing worldwide among men but rising among women due to recent changes in smoking patterns in both sexes. In Europe, the smoking epidemic has evolved different rates and times, and policy responses to it, vary substantially between countries. Differences in smoking prevalence are much more evident among European women reflecting the heterogeneity in cancer incidence rates. Other factors rather than smoking and linked to sex may increase women's susceptibility to lung cancer, such as genetic predisposition, exposure to sex hormones and molecular features, all of them linked to epidemiologic and clinical characteristics of lung cancer in women. However, biological bases of sex-specific differences are controversial and need further evaluation. This review focuses on the epidemiology and outcome concerning non-small cell lung cancer in women, with emphasis given to the Spanish population.

The optimal schedule and regimen of chemotherapy (CT) in association with chemoradiation has not been established in stage III non-small-cell lung cancer (NSCLC). We have compared three schedules of non-platinum-based CT plus either radiotherapy or chemoradiation. From May 2001 to June 2006, 158 patients with unresectable stage III NSCLC were enrolled in a randomized phase II trial with overall response rate (ORR) as the primary endpoint. The initial design included three arms: sequential CT followed by thoracic radiation (TRT); concurrent CT/TRT followed by consolidation CT; and induction CT followed by concurrent CT/TRT. However, based on the preliminary results of the RTOG 9410 trial, the sequential arm was closed when 19 patients had been enrolled. All patients received two cycles of docetaxel 40 mg/m(2) days 1 and 8 plus gemcitabine 1200 mg/m(2) days 1 and 8, as either induction or consolidation therapy. Concurrent CT/TRT consisted of docetaxel 20 mg/m(2) and carboplatin AUC 2 weekly plus 60 Gy TRT. No differences were found in ORR between the two arms (56% and 57%). Hematological toxicity was mild but significantly superior with consolidation CT; the esophagitis rate was similar in both arms (16% and 15%). With a median follow-up of 57 months, no differences were found in median survival (13.07 and 13.8 months) or 5-year survival (16.4% and 22%). This regimen cannot be recommended as an alternative to platinum-based CT/TRT although it has an acceptable toxicity profile and encouraging long-term survival data (ClinicalTrials.gov NCT01652820).

Introduction The clinical benefit and safety profile associated with first-line bevacizumab with doublet chemotherapy in patients with advanced non-squamous non-small cell lung cancer (NSCLC) was established in two large phase III studies, E4599 and AVAiL. SAiL, a single-arm phase IV study, was conducted to evaluate bevacizumab with a range of first-line chemotherapy regimens in a routine oncology practice setting. Methods This analysis of the SAiL data was undertaken to specifically evaluate bleeding adverse events (AEs) in this study, and to explore potential associations between bleeding and baseline patient and disease characteristics. Results In total, 2212 patients were evaluated. Bleeding AEs (any grade) occurred in 38.2% of patients (grade ≥3 bleeding AEs: 3.6%). Grade ≥3 pulmonary hemorrhage and central nervous system bleeding events were observed in 0.7% and 0.1% of patients, respectively. The incidence of grade ≥3 bleeding AEs was comparable across patient subgroups defined by central tumor location, tumor cavitation, histology, concomitant anticoagulation therapy and age. The majority (88.6%) of bleeding events resolved or improved, 10.2% persisted and 1.3% led to death; 10.2% of bleeding events required bevacizumab interruption or discontinuation. Conclusions This analysis from the SAiL trial reaffirms a comparable incidence of clinically significant bleeding associated with first-line bevacizumab and chemotherapy as previous phase III studies in NSCLC patients despite less stringent first-line selection criteria. Grade ≥3 bleeding appears to be comparable when analyzed for patient and tumor characteristics, including tumor cavitation and concomitant anticoagulation therapy. Most bleeding events resolved or improved, and interruption/discontinuation of bevacizumab was infrequent in a standard oncology practice setting.

Patients with advanced non-small-cell lung cancer (NSCLC) carrying epidermal growth factor receptor (EGFR) mutations can now have specific treatment based on the result of biomarker analysis and patients with rearrangements of the anaplastic lymphoma kinase (ALK) gene will probably soon be able to. This will give them better quality of life and progression-free survival than conventional chemotherapy. This consensus statement was conceived as a joint initiative of the Spanish Society of Medical Oncology (SEOM) and the Spanish Society of Pathology (SEAP), and makes diagnostic and treatment recommendations for advanced NSCLC patients based on the scientific evidence on biomarker use. It therefore provides an opportunity to improve healthcare efficiency and resource use, which will undoubtedly benefit these patients. Although this field is in continuous evolution, at present, with the available data, this panel of experts recommends that all patients with advanced NSCLC of non-squamous cell subtype, or non-smokers regardless of the histological subtype, should be tested for EGFR gene mutations within a maximum of 7 days from the pathological diagnosis. Involved laboratories must participate in external quality control programmes. In contrast, ALK gene rearrangements should only be tested in the context of a clinical trial, although the promising data obtained will certainly justify in the near future its routine testing in patients with no EGFR mutations. Lastly, routine testing for other molecular abnormalities is not considered necessary in the current clinical practice.

Gastroenteropancreatic neuroendocrine tumours (GEP NETs) represent a heterogenous family of tumours with growing incidence and challenging clinical management. Unlike other solid tumours, they have the ability to secrete different peptides and neuramines that cause distinct clinical syndromes. However, many are clinically silent until advanced disease. This guideline aims to provide practical recommendations for the diagnosis and treatment of GEP NETs. Most recent histological and staging classifications, as well as available therapeutic approaches, such as surgery, locoregional therapy, peptide receptor radionuclide therapy (PRRT) and hormonal or systemic therapy, are discussed in this manuscript, including some recent relevant achievements with novel targeted agents. Clinical presentation (with or without hormonal syndrome), histological tumour features (including proliferation index (Ki-67) and the presence or not of somatostatin receptors), tumour stage, and location of primary tumour and distant metastasis are all key issues that shall be taken into consideration to properly design and integrate the most adequate therapeutic strategy.

Oesophageal cancer is currently the eighth most common malignancy worldwide. The incidence varies enormously between geographic areas, with increased incidences (100/100,000) in Asia, and central and south Africa. The incidence of oesophageal cancer in Spain has been approximately 8/100,000 among men and 1/100,000 among women. Oesophageal cancers are histologically classifi ed as squamous cell carcinoma (SCC) or adenocarcinoma, both with different associated risk factors. While SCCs have become increasingly less common, the incidence of adenocarcinoma has risen steeply. In the SEOM Clinical Guidelines for Oesophageal Cancer we propose rules for adequate initial diagnosis and staging as well as treatment recommendations from early to advanced disease.

Although thyroid cancer represents less than 1% of malignant tumours, its increased incidence detected in recent years and the appearance and development of new drugs targeting specific molecular targets has attracted the attention of the doctors involved in this pathology, especially medical oncologists. For this reason it is important at this critical point, when treatment may be substantially changed, to establish and agree updated guidelines. These guidelines should incorporate the newly developed strategies that, although still preliminary in evidence level, will surely have an important role, especially in relapsed and refractory tumours, which are unsuitable for surgical or radio-iodine treatment. Particular histological and molecular features of these tumours must be taken into account in order to optimise therapeutic approaches.

Nowadays, treatment selection for most types of cancers is based on anatomical, histological and clinical criteria, which are defi ned by the selection criteria used in registration phase III trials. However, different cancers present distinct molecular features, so the current approach results in a lack of specificity of cancer therapy, which is associated with decreased efficacy and unnecessary toxicities and costs. Molecular diagnostics has proved able to predict the efficacy of selected targeted therapies. This allows the selection of specific treatments for different types of cancer, increasing their efficiency. Even though the number of treatments for solid tumours that can be selected based on molecular diagnostic tools is limited, much effort is being put into the identification of new biomarkers. This guideline reviews molecular diagnostic biomarkers that allow selection of specific therapies that have obtained regulatory approval as treatment of solid tumours.

While hepatocellular carcinoma (HCC) is a relatively common tumour with an annual incidence in the EU of 8 cases/100,000 inhabitants, bile tract carcinoma (BTC) is much less common, with an incidence of 4 cases per 100,000 inhabitants per year. In both cases, when planning treatment it is essential to perform accurate staging, evaluate hepatic functional reserve and performance status, and obtain the opinion of the patient. The only curative treatment is surgery. However, several interventional radiological techniques can help to achieve local disease control and the alleviation of symptoms. In addition, sorafenib (HCC) and chemotherapy (BTC) may contribute to prolong survival in patients with disseminated disease. Therefore, the therapeutic strategy should always be discussed and planned within a multidisciplinary tumour board.
