Background The mechanism of action of bevacizumab and erlotinib is quite different in the treatment of advanced non-small cell lung cancer (NSCLC). This study sought to compare the two targeted therapies in terms of sequential tumor response metrics. Patients and methods Parameters of radiological tumor response evaluation were assessed at baseline and periodically in 58 patients receiving either bevacizumab plus platinum-based chemotherapy (N=25) or erlotinib (N=33). Results Bevacizumab-treated patients had lower longest diameter at best response compared to the erlotinib group (p=0.011). The longest diameter, tumor volume and density significantly decreased from baseline to best response for the entire cohort and bevacizumab-treated patients; no difference was found in the erlotinib group. Conclusion Treatment with bevacizumab substantially improved tumor metrics between baseline and each cycle of treatment, as well as between baseline and best response, in patients with advanced NSCLC.

BACKGROUND/AIM The aim of the present study was to investigate the clinical significance of 7 single nucleotide polymorphisms (SNPs) of vascular endothelial growth factor A (VEGFA), endothelin receptor type A (EDNRA), nibrin (NBS1) and Fas cell surface death receptor (FAS) genes in patients with nasopharyngeal carcinoma (NPC). PATIENTS AND METHODS Genomic DNA was extracted from the peripheral blood specimens of 60 patients. Genotyping of 4 VEGFA polymorphisms, namely VEGFA -1154 G/A (rs1570360), -2578 A/C (rs699947), -1498 C/T (rs833061) and +936 C/T (rs3025039), as well as EDNRA SNP p.His323 (rs5333), NBS1 p.E185Q (rs1805794) and FAS -671 A/G (rs1800682) was performed by using Sanger sequencing. RESULTS The VEGFA +936 CC genotype was more frequent in tumors with bilateral infiltration of pterygoid plates compared to those with ipsilateral (76.9% vs. 69.6%, p=0.008) and no infiltration of pterygoid plates (76.9% vs. 68.8%, p=0.023). VEGFA -2578, VEGFA -1154 and VEGFA +936 were significantly associated with infiltration to the pterygoid processes (p=0.011, p=0.041 and p=0.032, respectively). EDNRA H323H TT genotype was marginally associated with infiltration to the ipsilateral medial pterygoid muscles (p=0.045). A trend towards longer overall survival was observed for VEGFA -2578 CC as compared to AC (HR=0.24, p=0.060). CONCLUSION The studied VEGFA SNPs seem to be associated with the local extension of the NPC and maybe with the clinical outcome of this patient group.

Background: We evaluated the association between pathogenic mutations and overall survival (OS) in patients with cancer referred to Hellenic Cooperative Oncology Group-affiliated Departments. Patients and methods: Patients referred from 12/1980 to 1/2017 had molecular testing (for research) of archival tumor tissue collected at the time of first diagnosis (non-metastatic, 81%; metastatic, 19%). Tumor-specific gene panels (16-101 genes) were used to identify pathogenic mutations in clinically relevant genes. NGS genotyping was performed at the Laboratory of Molecular Oncology, Aristotle University of Thessaloniki. Annotation of mutations was performed at MD Anderson Cancer Center. Results: We analyzed 3,084 patients (median age, 57 years; men, 22%) with sequencing data. Overall, 1,775 (58% of 3,084) patients had pathogenic mutations. The median follow-up was 7.52 years (95% CI, 7.39-7.61). In patients with non-metastatic tumors, after stratification by tumor type, increasing age, higher grade, and histology other than adenocarcinoma were associated with shorter OS. OS was also shorter in patients with pathogenic TP53 (HR=1.36; p

AIM The purpose of the Imadje study was to confirm the efficacy and safety of imatinib, following resection of kit-positive gastrointestinal stromal tumour (GIST), in the adjuvant setting in the Greek population. PATIENTS AND METHODS A total of 34 adult patients already receiving imatinib were enrolled. Recurrence-free (RFS) and overall survival, as well as time to treatment failure and safety were assessed. RESULTS Overall survival could not be estimated in the present study, as no death occurred. Overall, 91.2% of patients were recurrence-free at 36 months, while the median time to treatment failure was 35 months. No new or unexpected safety findings were observed. Mutation analysis in 14 patients showed that the most frequent mutations were located in KIT exon 11 (64.3%) and exon 9 (28.6%). Univariate analysis showed that only surgical resection with a margin classification of R0 was associated with better RFS. CONCLUSION Adjuvant treatment with imatinib for 3 years in patients with intermediate to high risk of recurrence was proven to prolong RFS, while being well-tolerated and not exhibiting a negative impact on patient compliance with therapy.

INTRODUCTION AND OBJECTIVE:Prostate cancer (PCa) is one of the most common neoplasms in Europe, with annual incidence of 336.000. PCa patients frequently encounter health-related quality of life (Q...

Background/Aim: KRAS mutations are reported in 20-25% of non-small cell lung cancer (NSCLC) and their prognostic role is unclear. We studied KRAS and EGFR genotyping in Greek NSCLC patients. Patients and Methods: KRAS and EGFR genotypes were centrally evaluated in 421 NSCLC patients (diagnosed September 1998 -June 2013) and associated with clinicopathological parameters. Outcome comparisons were performed in 288 patients receiving first line treatment. Results: Most patients were male (78.6%), >60 years old (63.9%), current smokers (51.1%), with adenocarcinoma histology (63.9%). EGFR and KRAS mutations were found in 10.7% and 16.6% of all histologies, respectively, and in 14.9% and 21.9% of adenocarcinomas. At 4.5 years median follow-up, KRAS status was an independent negative prognostic factor for overall survival (OS, p=0.016). KRAS mutations conferred 80% increased risk of death in patients receiving first-line treatment (p=0.002). Conclusion: The presence of KRAS mutations is an independent negative prognosticator among Greek NSCLC patients and an independent response predictor to first line treatment.

Simple Summary Angiogenesis and apoptosis play a pivotal role in the pathogenesis and clinical course not only of nasopharyngeal cancer (NPC), but also of other subgroups of head and neck cancer (HNC), such as laryngeal cancer. Thus, the aim of this study was to investigate the clinical significance of genetic polymorphisms in four pivotal angiogenesis- and apoptosis-related genes (VEGFA, FAS, EDNRA and NBS1) in HNC patients. Thirty-four genetic variants located in the studied genes were assessed. Two of them (VEGFA rs13207351 and FAS rs2234768) were associated with overall survival for patients with laryngeal cancer and NPC, respectively, with VEGFA rs13207351 showing the most promise for its prognostic value in the subgroup of laryngeal cancer patients. This study suggests that genetic variations in angiogenesis- and apoptosis-related genes may be useful in the management of HNC patients. Abstract Head and neck cancer (HNC) is a significantly heterogeneous disease and includes malignancies arising from different anatomical sites, such as nasopharyngeal cancer (NPC) and laryngeal cancer (LC). In the current study, polymorphisms located in angiogenesis- and apoptosis-related genes (VEGFA, FAS, EDNRA and NBS1) were evaluated regarding their clinical significance in HNC patients. In total, 333 HNC patients were enrolled in this study and 34 variants located on the aforementioned genes were genotyped via Sanger sequencing. LC patients, homozygous A for VEGFA rs13207351, had shorter overall survival (OS) as opposed to homozygous G (Hazard ratio (HR) = 2.06, Wald’s p = 0.017) upon adjustment for age, disease stage, and surgery. Following the dominant model, LC patients carrying the A allele had a marginally significantly higher risk for death (HR = 1.72, p = 0.059). NPC patients heterozygous (CT) for FAS rs2234768 had a marginal but significantly higher risk of death compared to those with homozygosity for the T allele (HR = 2.22, p = 0.056). In conclusion, rs13207351 (VEGFA) and rs2234768 (FAS) polymorphisms seem to have prognostic significance in HNC, with VEGFA rs13207351 showing the most promise in this subgroup of LC patients.

Background/aim Effective targeted therapies for triple-negative breast cancer (TNBC) are limited. In a subset of TNBC, androgen receptor (AR) plays an important role, while the human proviral integration site for Moloney murine leukemia virus-1 (PIM1) overexpression is also implicated. PIM1 kinases phosphorylate AR, thus regulating its transcriptional activity, regardless of the presence or not of androgens. We evaluated the expression of AR and PIM1 and their prognostic significance in TNBC. Materials and methods AR and PIM1 transcripts were quantified by quantitative reverse transcription polymerase chain reaction in formalin-fixed paraffin-embedded tumor from 141 patients with TNBC. Results AR was expressed in 38.3%, PIM1 in 10.6%, while co-expression of AR and PIM1 was detected in 7/141 cases (5.0%). No prognostic significance of AR or PIM1 was reached for overall or disease-free survival. Conclusion Co-expression of AR and PIM1 exists in only in a small percentage of patients with TNBC. The implications of this finding in the therapeutic management of patients with TNBC should be investigated in larger patient cohorts.

Real-world data have suggested a detrimental effect of steroid use in patients with advanced non-small-cell lung cancer (NSCLC) receiving immunotherapy. However, previous studies included heterogeneous cohorts of patients receiving different lines of treatment with several immuno-oncology agents and various combinations of chemotherapy and immuno-oncology agents.A comprehensive clinicopathologic database of patients with NSCLC and programmed cell death ligand 150% treated with frontline pembrolizumab monotherapy was constructed in 14 centers in Italy, Spain, Greece, and Switzerland. A multivariate analysis adjusting for the established prognostic factors was performed using a Cox regression model.For the 265 eligible patients, the median age at diagnosis was 67 years, 66% were male, 90% were current or former smokers, 18% had had an Eastern Cooperative Oncology Group performance status of 2 or 3. Of the NSCLC subtypes, 64% were adenocarcinoma and 25% were squamous cell. Of the patients, 18% had had brain metastases at diagnosis and 24% had received steroids before or during pembrolizumab treatment. The median time to progression was 4.4 months with and 13.7 months without steroid use (hazard ratio [HR], 2.55; 95% confidence interval [CI], 1.69-3.85; log-rank P .001). The median survival was 22.5 months for the whole cohort, 7.7 months for the steroid group, and not reached for the non-steroid group (HR, 3.64; 95% CI, 2.34-5.68; log-rank P .001). On multivariate analysis accounting for all established prognostic variables, steroid use was still independently associated with a high risk of progression (HR, 1.864; 95% CI, 1.179-2.949; P = .008) and death (HR, 2.292; 95% CI, 1.441-3.644; P .001) CONCLUSIONS: In patients with advanced NSCLC and programmed cell death ligand 1 expression50% receiving frontline pembrolizumab monotherapy, any use of steroids before or during treatment was associated with an 86% increase in the risk of progression and a 2.3-fold increase in the risk of death, even accounting for palliative indication-related bias, including the presence of central nervous system metastasis. The use of steroids for palliative indications should be restricted to absolutely necessary for patients receiving immuno-oncology monotherapy.

Simple Summary Data on the prognostic and predictive value of germline cancer predisposing pathogenic/likely pathogenic variants (P/LPVs) in patients with pancreatic ductal adenocarcinoma is limited. This research was a study of germline testing of 62 cancer susceptibility genes in 549 unselected patients with pancreatic cancer. We reported a significant proportion of European patients with pancreatic cancer carrying P/LPVs in clinically significant genes, irrespectively of age, family history or disease stage. Importantly, P/LPVs were identified in pancreatic cancer-associated genes and in homologous recombination repair genes in 4.0% and 7.7% of patients, respectively. The presence of any P/LPVs was associated with improved overall survival univariately; however, it did not retain its independent prognostic significance in multivariate analysis. The presence of P/LPVs in homologous recombination repair genes did not predict benefit from platinum-based treatment. These results should be prospectively validated through universal genetic testing of patients with pancreatic cancer, taking into consideration the administration of newer treatments. Abstract Our aim was to determine the prevalence, prognostic and predictive role of germline pathogenic/likely pathogenic variants (P/LPVs) in cancer predisposing genes in patients with pancreatic ductal adenocarcinoma (PDAC). Germline testing of 62 cancer susceptibility genes was performed on unselected patients diagnosed from 02/2003 to 01/2020 with PDAC, treated at Hellenic Cooperative Oncology Group (HeCOG)-affiliated Centers. The main endpoints were prevalence of P/LPVs and overall survival (OS). P/LPVs in PDAC-associated and homologous recombination repair (HRR) genes were identified in 22 (4.0%) and 42 (7.7%) of 549 patients, respectively. P/LPVs were identified in 16 genes, including ATM (11, 2.0%) and BRCA2 (6, 1.1%), while 19 patients (3.5%) were heterozygotes for MUTYH P/LPVs and 9 (1.6%) carried the low-risk allele, CHEK2 p.(Ile157Thr). Patients carrying P/LPVs had improved OS compared to non-carriers (22.6 vs. 13.9 months, p = 0.006). In multivariate analysis, there was a trend for improved OS in P/LPV carriers (p = 0.063). The interaction term between platinum exposure and mutational status of HRR genes was not significant (p-value = 0.35). A significant proportion of patients with PDAC carries clinically relevant germline P/LPVs, irrespectively of age, family history or disease stage. The predictive role of these P/LPVs has yet to be defined. ClinicalTrials.gov Identifier: NCT03982446.

Background: In this real-world multicenter study we addressed the activity of post-progression anticancer treatments after first-line pembrolizumab in advanced non-small cell lung cancer (NSCLC) patients with PD-L1 ≥50%. Methods: Clinico-pathological data of PD-L1 ≥50% advanced NSCLCs who failed first-line pembrolizumab were collected in 14 Oncologic Centers from different European countries. Types of subsequent anticancer treatment and outcomes on salvage chemotherapy or pembrolizumab beyond progression with or without the addition of local ablative therapies were reported. Results: Out of 173 patients, 100 had progressed on pembrolizumab, of which 60 patients (60%) met eligibility criteria and were treated with either salvage chemotherapy (42/60, 70%) or pembrolizumab beyond progression (18/60, 30%). Overall, median age was 66 years, 63.3% were male, 60.0% had a performance status of 0–1, 88.3% were smokers and 61.7% had adenocarcinoma histology. In patients evaluable for response, objective response rate to salvage chemotherapy was 41.9%, with no significant difference according to the type of regimen (42.9% for platinum-based and 40.0% for single-agent chemotherapy). Median progression-free survival (PFS) to salvage chemotherapy was 4.5 months. Among patients treated with pembrolizumab beyond progression, 13 out of 18 patients (72.2%) had progressive disease in ≤2 organ sites, of whom 9 (69.2%) were managed with the addition of local ablative therapies consisting of radiation at progressive lesion(s). No significant difference was noted in terms of post-progression survival between the salvage chemotherapy and the pembrolizumab beyond progression groups of patients (6.9 versus 8.1 months, respectively, P=0.08). Conclusions: In PD-L1 ≥50% advanced NSCLCs who progress on first-line pembrolizumab, salvage chemotherapy is associated with a remarkable anticancer activity, while select patients may benefit from continuation of pembrolizumab beyond progression, with the possible addition of local ablative radiotherapy in oligoprogressive cases.

The authors conducted a multicenter retrospective study on the outcome of programmed death-ligand 1 tumor proportion score≥50% advanced non-small cell lung cancer patients treated with first-line pembrolizumab according to the presence/absence of brain metastases. A total of 282 patients were included, of whom 56 had brain metastases that were treated with upfront local radiation therapy in 80.3% of cases. The overall response rate was 39.2% and 44.4% in patients with and without brain metastases (P=0.48), respectively, while intracranial response rate and intracranial disease control rate were 67.5% and 85.0%, respectively. The median time-to-treatment failure (TTF) and overall survival (OS) were 4.2 and 9.9 months versus 10.8 and 26.5 months for patients with and without brain metastases (P=0.06 and 0.05, respectively). Drug discontinuation rate due to treatment-related adverse events was 10.7% and 10.2% in patients with and without brain metastases, respectively. Multivariate analysis showed that baseline steroids was an independent predictor for a worse OS (P

Background The advanced lung cancer inflammation index [ALI: body mass index × serum albumin/neutrophil-to-lymphocyte ratio (NLR)] reflects systemic host inflammation, and is easily reproducible. We hypothesized that ALI could assist guidance of non-small-cell lung cancer (NSCLC) treatment with immune checkpoint inhibitors (ICIs). Patients and methods This retrospective study included 672 stage IV NSCLC patients treated with programmed death-ligand 1 (PD-L1) inhibitors alone or in combination with chemotherapy in 25 centers in Greece and Germany, and a control cohort of 444 stage IV NSCLC patients treated with platinum-based chemotherapy without subsequent targeted or immunotherapy drugs. The association of clinical outcomes with biomarkers was analyzed with Cox regression models, including cross-validation by calculation of the Harrell's C-index. Results High ALI values (>18) were significantly associated with longer overall survival (OS) for patients receiving ICI monotherapy [hazard ratio (HR) = 0.402, P < 0.0001, n = 460], but not chemo-immunotherapy (HR = 0.624, P = 0.111, n = 212). Similar positive correlations for ALI were observed for objective response rate (36% versus 24%, P = 0.008) and time-on-treatment (HR = 0.52, P < 0.001), in case of ICI monotherapy only. In the control cohort of chemotherapy, the association between ALI and OS was weaker (HR = 0.694, P = 0.0002), and showed a significant interaction with the type of treatment (ICI monotherapy versus chemotherapy, P < 0.0001) upon combined analysis of the two cohorts. In multivariate analysis, ALI had a stronger predictive effect than NLR, PD-L1 tumor proportion score, lung immune prognostic index, and EPSILoN scores. Among patients with PD-L1 tumor proportion score ≥50% receiving first-line ICI monotherapy, a high ALI score >18 identified a subset with longer OS and time-on-treatment (median 35 and 16 months, respectively), similar to these under chemo-immunotherapy. Conclusions The ALI score is a powerful prognostic and predictive biomarker for patients with advanced NSCLC treated with PD-L1 inhibitors alone, but not in combination with chemotherapy. Its association with outcomes appears to be stronger than that of other widely used parameters. For PD-L1-high patients, an ALI score >18 could assist the selection of cases that do not need addition of chemotherapy., Highlights • ALI is prognostic and predictive for patients with advanced NSCLC treated with immunotherapy monotherapy, but not chemo-immunotherapy. • Its association with outcomes is stronger than that of other parameters (PD-L1 TPS, NLR, lung immune prognostic index, EPSILoN). • For PD-L1-high patients, an ALI score >18 could assist the selection of cases that do not need addition of chemotherapy.

1566 Background: Quality of life of cancer patients is a critical part of cancer care. Symptom management is evolving as a multidisciplinary approach, and is increasingly delivered through a combination of physical and remote interactions. CareAcross is an online platform offering personalized, guidelines-based support to cancer patients, that complements physicians’ support and enables remote monitoring. This analysis investigated the improvement in the quality of life of cancer patients delivered through such remote support. Methods: Patients engage with an online interactive platform to receive personalized support based on a variety of parameters, through algorithms incorporating their exact diagnoses, treatments and comorbidities, and more. For symptom management, patients report the presence of specific side-effects via brief questionnaires; for each side-effect reported, they receive tailored support (text and multimedia) to help overcome it. These online questionnaires are repeated periodically to capture the outcome of the supportive process, and provide additional support as necessary. A retrospective analysis evaluated the efficacy of the personalized support: each patient’s reported side-effects were compared before versus after receiving the support, hence calculating the reduced incidence. Results: 2203 patients from 8 countries, with breast, lung, prostate or colorectal cancer (1563, 404, 159 and 77, respectively) reported side-effects, received support, and updated their reports at least once. The median follow-up period was 4.9 months. The patient-reported outcomes on their quality of life revealed substantial improvement, regardless of cancer type (lowest recorded improvement = 25.7%). Commonly reported side-effects included sleep problems, dry mouth, constipation, changes in food taste, and more (see Table). Side-effects reported in specific cancer types also showed substantial improvement, including hot flushes (breast; 32.0% improvement), dyspnea (lung; 38.1%), bowel dysfunction (prostate; 80%) and others. The efficacy of the support to breast, prostate or colorectal cancer patients was similar; support to lung cancer patients exhibited the lowest efficacy (p < 0.05). Fatigue was the most common side-effect. It was also the most resistant to improvement compared to all others (p < 0.05). Conclusions: Digital remote support of cancer patients is a realistic option to improve quality of life. Randomized controlled trials can help quantify its impact on health economics, hospital admissions, resource utilization, and other aspects.[Table: see text]

BACKGROUND: Prevention of bone metastases is a major issue for breast cancer patients, as it would improve quality of life in a population where long survival is anticipated. PATIENTS AND METHODS: Early breast cancer patients, who had been treated with anthracycline-based chemotherapy within two randomized trials, were included in the study. We evaluated, by quantitative reverse transcription–polymerase chain reaction, 819 formalin-fixed paraffin-embedded tumor tissue samples for mRNA expression of RANK, OPG, and RANKL, as well as their ratios, for potential prognostic significance for the development of bone metastases and also for disease-free survival (DFS) and overall survival. RESULTS: Median age was 52.7 years, whereas 54.2% of the patients were postmenopausal and 78.3% estrogen receptor/progesterone receptor positive. After a median follow-up of 119.9 months, 226 patients (27.6%) had died and 291 patients (35.5%) had disease progression. Low mRNA expression of RANKL was associated with postmenopausal status and greater number of positive lymph nodes (P = .002 and P

Background Many breast cancer patients experience adverse effects of cancer or treatment, which can considerably decrease quality of life (QoL). The current strategy of supporting breast cancer patients does not meet their needs due to the limited personalized-based approach in rehabilitation plan and the lack of healthcare, financial and other resources. ASCAPE (Artificial intelligence Supporting CAncer Patients across Europe) is a collaborative research project involving 15 partners from 7 countries, including academic medical centers, small and medium-sized enterprises, research centers and universities, aiming to leverage the recent advances in Big Data and AI (Artificial Intelligence) to support cancer patients’ QoL and health status. Specifically, ASCAPE aims to provide personalized- and AI-based predictions for QoL issues in breast cancer patients as well as suggest potential interventions to their physicians. Trial design During the first part of the project, large-scale retrospective datasets with breast cancer patients will be analyzed to develop and train AI-based models for specific QoL issues. During the second part of the project, a multicenter prospective longitudinal study is planned. Eligible patients will be followed for one year with validated questionnaires regarding different QoL issues, and wearables that will collect active monitoring data on physical activity, sleep pattern, and heart rate. The collected data will be used to further train and optimize the AI-based models and personalized-based intervention suggestions.Based on the retrospective and prospective data, an ASCAPE-integrated prototype will be developed, enabling personalized- and AI-based predictions and intervention suggestions. This approach will be evaluated at the end of the prospective study regarding patients´ and physicians´ experience as well as health economics. Eligibility criteria Breast cancer patients planned for curative treatment with surgery with or without oncological therapy or breast cancer patients at least 1 year post-treatment (except endocrine therapy) will be eligible for the prospective study. Specific aims 1.To develop and optimize AI-based predictions for QoL issues in breast cancer patients as well as potential intervention suggestions.2.To evaluate the AI-based follow-up approach for breast cancer survivors in terms of patients´ experience, physicians´ experience, and health economics. Statistical methods For discrete QoL outcome variables, ASCAPE will examine the efficiency of classification-based machine learning models trained using decision tree learning algorithms, nearest-neighbors based algorithms, probabilistic learning algorithms, support vector machines and (deep) neural networks. Regressive counterparts of aforementioned methods will be analyzed for numeric QoL outcome variables including also regression specific methods (e.g., ridge regression, lasso regression and elastic net regression). The accuracy of trained models will be estimated relying on standard machine learning validation procedures such as the K-fold cross-validation and leave-one-out cross-validation. The ASCAPE platform will utilize state-of-the-art explainability techniques to make the machine learning models’ predictions transparent and comprehensible for the patient and the physician.Present accrual and target accrual Four retrospective datasets will be used for the first part of the project including approximately 18,000 breast cancer patients. For the prospective study, it is planned to be included about 30 patients monthly during a period of 12 months.

e21651 Background: We retrospectively analysed real-world clinical outcomes of patients with advanced non-small-cell lung cancer (NSCLC) harbouring high PD-L1 expression ( > 50%) and treated with first-line pembrolizumab, following the Keynote 024 regimen. In the recent PePS2 trial and Checkmate 817, we see that some patients with PS2 could benefit from a durable response to checkpoint inhibitors. However, current data does not suggest an improvement in median OS compared to historical data on chemotherapy in this setting. Methods: Data was collected by 16 participating centers. The trial was approved by local ethics committees and patients included signed a general consent form. All patients with NSCLC with PD-L1 expression ≥50%, treated with first-line pembrolizumab were included, from the introduction of first-line pembrolizumab to the present. We collected medical data from patient files, pathology reports and laboratory reports for all patients. Patient characteristics, comorbidities, Eastern Cooperative Oncology Group (ECOG) performance status (PS), and tumor characteristics were reported. Overall survival (OS) was calculated from the date of the first cycle of pembrolizumab to death and estimated through the Kaplan-Meier method. Results: 302 patients were identified, of which 247 with a PS of 0-1, 52 with a PS of 2. Patients (3) with PS3 were excluded. The median age was 69 with a range from 19 to 87 years. There were 193 males and 106 females, 90% were active or former smokers, 19% had brain lesions at diagnosis. Only 14% received brain radiotherapy. Median OS was 7.2 months among patients with PS2, while not reached for those with PS0-1 (HR 3.80, 95% confidence interval 2.49-5.78). Conclusions: Patients with a PS of 2 had significantly worse survival than those with PS0-1. The retrospective nature of our trial and lack of a control arm treated with chemotherapy do not allow us to postulate as to whether PS is predictive or prognostic. Our data suggests worse survival among NSCLC patients with PS2 treated with front-line pembrolizumab. A prospective randomized trial comparing immunotherapy to chemotherapy or chemo-immunotherapy in this population would be welcome.

Several studies support an important role of angiogenesis in breast cancer growth and metastasis. The main objectives of the study were to investigate the immunohistochemical expression of vascular endothelial growth factor (VEGF) family ligands (VEGF-A and VEGF-C) and receptors (VEGFR1, VEGFR2 and VEGFR3) in breast cancer and their associations with clinicopathological parameters, cancer subtypes/subgroups and patient outcome. Formalin-fixed paraffin-embedded tumor tissue samples were collected from early-stage breast cancer patients treated with anthracycline-based chemotherapy within a randomized trial. Immunohistochemistry was performed on serial 2.5 μm thick tissue sections from tissue microarray blocks. High VEGF-A, VEGF-C, VEGFR1, VEGFR2 and VEGFR3 protein expression was observed in 11.8% (N = 87), 80.8% (N = 585), 28.1% (N = 202), 64.6% (N = 359) and 71.8% (N = 517) of the cases, respectively. Significant associations were observed among all proteins (all p-values

Background CareAcross is a digital platform dedicated to support, inform and engage with cancer patients. It also collects medical and other data, and generates real world evidence. Methods In an effort to collect and analyze information from breast cancer patients regarding side effects in relation to their treatments and supplements intake, we contacted 5373 patients in the UK, Germany, France, Spain and Italy. 547 had triple negative breast cancer (TNBC) and the remaining 4826 had other breast cancer subtypes (non-TNBC). All data was collected anonymously, with strong privacy and security controls. Results Different regimens were given as adjuvant or as systemic treatments. AC treatment was given to 10% of TNBC vs 5% of non-TNBC patients; FEC-T to 18% vs 11%, FEC to 9% vs 7%, taxanes to 39% vs 22% and platinum-based chemotherapy to 14% vs 2%, respectively. Among non-TNBC patients, 12% received Trastuzumab and 52% received hormonal treatment. Some of the patients were asked regarding side effects as well as vitamins and supplements intake. Among them, 136 TNBC patients reported an average of 3.0 side effects (95% CI 2.6-3.5), 22% more than those reported by 1015 non-TNBC patients (2.5 side effects; 95% CI 2.4-2.6); p = 0.03. Similarly, an average of 3.6 vitamins and supplements was reported by 111 TNBC patients (95% CI 2.9-4.3), 15% more compared to 854 non-TNBC patients (3.1 supplements; 95% CI 2.9-3.3); p = 0.22. An analysis of the patients reporting at least 1 side-effect showed 120 TNBC patients with an average of 3.5 side effects (95% CI 3.0-3.9), 17% more than 862 non-TNBC patients (3.0 side effects, 95% CI 2.8-3.1); p = 0.05. Regarding consumption of at least 1 vitamin/supplement, the average intake across 85 TNBC patients was 4.7 (9.5% CI 3.9-5.5), 23% more than 697 non-TNBC patients (3.8 vitamins/supplements, 95% CI 3.5-4.0); p = 0.04. Conclusions The real world evidence obtained through an international analysis shows that TNBC patients receive more toxic treatments due to the aggressive disease, as expected. TNBC patients experience significantly more side effects compared to non-TNBC patients. They also consume more vitamins and supplements; the difference across patients reporting at least one vitamin/supplement was larger and statistically significant.

Background Real-world data regarding clinical outcomes associated with first-line pembrolizumab (pembro) monotherapy among specific subgroups of NSCLC patients are lacking. Methods A comprehensive clinicopathological database of patients with NSCLC and PD-L1>50% treated with frontline pembro in 14 centers in Italy, Spain, Greece and Switzerland was retrospectively created. Post-progression outcomes have been previously reported. Clinical outcomes in specific subgroups of interest are presented in the current report. Analysis was performed using the SAS 9.3 software. Multivariate analysis was performed with the Cox regression model. Results Among 173 eligible patients, median age at diagnosis was 68 years, 65% were male, 88% were current or former smokers, 25% had an ECOG PS > =2, histology was 67% adeno, 21% squamous, 20% had brain mets, 15% had liver mets at diagnosis and 28% received steroids at the beginning and/or during treatment. Thirty patients (17.4%) received pembro despite having non-metastatic disease (stage I-IIIC), as deemed medically inoperable or ineligible for definite chemo-radiotherapy. Hazard Ratios for OS, with corresponding 95% CIs and p-values for specific subgroups were as follows: Elderly patients ( >70 years): HR = 0.85 (0.52-1.38), p = 0.51; Brain mets: HR = 1.17 (0.63-2.18), p = 0.63; Stage I-IIIC: HR = 0.56 (0.22-1.39), p = 0.21; PS > =2: HR = 1.73 (1.55-1.84), p Conclusions Real-world data in a large retrospective cohort of patients with NSCLC and PD-L1>50% indicate that 1) Pembro frontline is also active in inoperable stage I-IIIC patients, 2) Elderly patients (>70 years) derive similar survival benefit to younger ones, except from those with PS > =2, 3) Steroid use at the beginning and/or during treatment is associated with a three-fold increase in the risk of death.

Background The shift towards an earlier diagnosis of breast cancer (BC) highlights the need for biomarkers that would identify patients at risk for relapse and metastatic spread and indicate the potential value of additional treatment strategies. Osteopontin (OPN) is a matricellular protein that has been suggested to be a potential biomarker in BC. In the present study, we used archived BC patient samples to assess the clinical utility of OPN. Methods Formalin-fixed paraffin-embedded tumor tissue samples from 975 patients were collected from two large phase III randomized adjuvant chemotherapy trials (HE10/97 and HE10/00) that included patients with high risk BC. All tissue samples were assessed for ER, PgR, Ki67 and HER2 protein expression. OPN protein and mRNA expression was evaluated using immunohistochemistry and quantitative reverse transcription-polymerase chain reaction, respectively. Results OPN mRNA expression data were available for 814 patients, whereas OPN protein expression data were available for 546 patients. The majority of patients were ER/PgR-positive (78.3%), HER2-negative (76.5%) and Ki67-positive (55.2%) and had received adjuvant radiation therapy (76.8%) and hormonal therapy (81.1%). OPN mRNA expression was significantly associated with age (60.9% in high OPN tumors vs. 54.1% in low OPN tumors, p = 0.047), ER/PgR-negative status (25.7 vs. 17.2%, p = 0.004) and BC subtypes (p = 0.021). In addition, high OPN mRNA expression was significantly associated with reduced DFS (HR 1.26, 95% CI 1.00–1.59, Wald’s p = 0.050) and OS (HR 1.37, 95% CI 1.05–1.78, p = 0.019), while it retained its prognostic significance for both DFS (HR 1.39, 95% CI 1.10–1.77, p = 0.007) and OS (HR 1.54, 95% CI 1.61–2.05, p = 0.003) in the multivariate analysis. Conclusions We showed that high OPN mRNA expression is associated with decreased DFS and OS in a large cohort of BC patients treated with adjuvant chemotherapy in a clinical trial setting. Our results suggest that OPN may serve as a prognostic factor and a potential target for therapy.

Background Stromal tumor infiltrating lymphocytes (TILs) density is an outcome predictor in triple-negative breast cancer (TNBC). Herein we asked whether TILs are related to coding mutation load and to the chemical class of the resulting mutated amino acids, i.e., charged, polar, and hydrophobic mutations. Methods We examined paraffin tumors from TNBC patients who had been treated with adjuvant chemotherapy mostly within clinical trials (training cohort, N = 133; validation, N = 190) for phenotype concordance; TILs density; mutation load and types. Results Concordance of TNBC phenotypes was 42.1% upon local / central, and 72% upon central / central pathology assessment. TILs were not associated with mutation load, type and class of mutated amino acids. Polar and charged mutation patterns differed between TP53 and PIK3CA (p50% TILs tumors (training p = 0.003; validation p = 0.015). Conclusions TILs density is unrelated to mutation load in TNBC, which may be regarded as an unstable phenotype. If further validated, hydrophobic mutations along with TILs density may help identifying TNBC patients in higher risk for relapse.

Background-Aim Early breast cancer is a heterogeneous disease, and, therefore, prognostic tools have been developed to evaluate the risk for distant recurrence. In the present study, we sought to develop a risk for recurrence score (RRS) based on mRNA expression of three proliferation markers in high-risk early breast cancer patients and evaluate its ability to predict risk for relapse and death. In addition the Adjuvant! Online score (AOS) was also determined for each patient, providing a 10-year estimate of relapse and mortality risk. We then evaluated whether RRS or AOS might possibly improve the prognostic information of the clinical treatment score (CTS), a model derived from clinicopathological variables. Methods A total of 1,681 patients, enrolled in two prospective phase III trials, were treated with anthracycline-based adjuvant chemotherapy. Sufficient RNA was extracted from 875 samples followed by multiplex quantitative reverse transcription-polymerase chain reaction for assessing RACGAP1, TOP2A and Ki67 mRNA expression. The CTS, slightly modified to fit our cohort, integrated the prognostic information from age, nodal status, tumor size, histological grade and treatment. Patients were also classified to breast cancer subtypes defined by immunohistochemistry. Likelihood ratio (LR) tests and concordance indices were used to estimate the relative increase in the amount of information provided when either RRS or AOS is added to CTS. Results The optimal RRS, in terms of disease-free survival (DFS) and overall survival (OS), was based on the co-expression of two of the three evaluated genes (RACGAP1 and TOP2A). CTS was prognostic for DFS (p3 positive nodes (LR-Δχ2 23.9, p3 positive nodes.

Bone metastases are often asymptomatic and are not diagnosed until after the onset of bone pain. However, bone structural integrity may have diminished considerably before pain onset, resulting in increased risk of skeletal-related events. Therefore, we evaluated whether bisphosphonate therapy was differentially beneficial depending on initiation before or after the onset of bone pain.Exploratory analyses were performed in patients with bone metastases from breast cancer or lung cancer/other solid tumors enrolled in two randomized trials comparing monthly zoledronic acid versus pamidronate (breast cancer) or placebo (lung cancer/other solid tumors). Analyses included proportion of patients with one or more skeletal-related events, time to first skeletal-related event, and skeletal morbidity rate in patients with and without baseline pain.Approximately 80 % of patients reported baseline pain. Similar to overall trial results, zoledronic acid reduced the skeletal morbidity rate in all groups. Although some subsets lacked statistical power, benefits were generally greater in patients without baseline pain. For example, in breast cancer, zoledronic acid increased the 25th quartile of time to first skeletal-related event versus pamidronate by 522 days in patients with no baseline pain (median not reached for either group), but by only 10 days in patients with baseline pain. Similar trends were observed in lung cancer.Benefits from zoledronic acid appeared to be greater if introduced before bone pain onset. Early diagnosis and treatment of bone metastases may delay onset of skeletal-related events.

The current third consensus on the systemic treatment of non-small-cell lung cancer (NSCLC) builds upon and updates similar publications on the subject by the Central European Cooperative Oncology Group (CECOG), which has published such consensus statements in the years 2002 and 2005 (Zielinski CC, Beinert T, Crawford J et al. Consensus on medical treatment of non-small-cell lung cancer--update 2004. Lung Cancer 2005; 50: 129-137). The principle of all CECOG consensus is such that evidence-based recommendations for state-of-the-art treatment are given upon which all participants and authors of the manuscript have to agree (Beslija S, Bonneterre J, Burstein HJ et al. Third consensus on medical treatment of metastatic breast cancer. Ann Oncol 2009; 20 (11): 1771-1785). This is of particular importance in diseases in which treatment options depend on very particular clinical and biologic variables (Zielinski CC, Beinert T, Crawford J et al. Consensus on medical treatment of non-small-cell lung cancer--update 2004. Lung Cancer 2005; 50: 129-137; Beslija S, Bonneterre J, Burstein HJ et al. Third consensus on medical treatment of metastatic breast cancer. Ann Oncol 2009; 20 (11): 1771-1785). Since the publication of the last CECOG consensus on the medical treatment of NSCLC, a series of diagnostic tools for the characterization of biomarkers for personalized therapy for NSCLC as well as therapeutic options including adjuvant treatment, targeted therapy, and maintenance treatment have emerged and strongly influenced the field. Thus, the present third consensus was generated that not only readdresses previous disease-related issues but also expands toward recent developments in the management of NSCLC. It is the aim of the present consensus to summarize minimal quality-oriented requirements for individual patients with NSCLC in its various stages based upon levels of evidence in the light of a rapidly expanding array of individual therapeutic options.

Background The prognostic/predictive value of aberrant MYC gene copies and protein expression is not clear in breast cancer. Patients and Methods Early breast cancer patients were treated with anthracycline-containing chemotherapy within 2 randomized adjuvant trials. MYC gene and centromere-8 status, as well as Myc protein expression were investigated on 1060 paraffin tumors with fluorescence in situ hybridization and immunohistochemistry, respectively. Results MYC amplification was present in 45% and polysomy-8 in 23% of the tumors. Cytoplasmic staining was observed in 60% and nuclear staining in 26% of the tumors, strongly correlating with each other but not with MYC gene status. MYC gene amplification in the absence of polysomy-8 was associated with adverse disease-free survival (DFS) and overall survival (OS), and remained as an independent unfavorable prognostic factor in multivariate analysis (Wald P = .022 for DFS; P = .032 for OS), whereas patients with MYC amplification and polysomy-8, with polysomy-8 only, and with normal MYC without polysomy-8 performed significantly better compared with those with MYC gene amplification only. Nuclear Myc protein expression benefitted patients treated with paclitaxel (interaction P = .052 for DFS; P = .049 for OS). This interaction remained independently significant in multivariate analysis for OS (overall P = .028). Conclusion The effect of MYC gene status on breast cancer patient outcome seems to depend on the underlying chromosomal instability and appears unfavorable for tumors with MYC amplification without polysomy. Nuclear Myc protein expression seems predictive for benefit from adjuvant paclitaxel. These data might aid in the interpretation of relevant findings from large clinical trials.

Early clinical studies of tyrosine kinase inhibitors (TKIs) that target the EGFR in patients with advanced non-small-cell lung cancer (NSCLC) showed that some patients experienced rapid, durable, complete or partial responses. These data were the basis for attempts to identify specific subgroups of patients who would further benefit from these agents. The discovery of somatic mutations in EGFR that correlated with sensitivity to TKIs identified a plausible explanation for these observations. Clinical and pathological factors such as female sex, never having smoked, Asian origin and adenocarcinoma histology correlate with the presence of EGFR mutations and objective responses to TKIs in patients with NSCLC. Recent studies in metastatic colorectal cancer highlighted that somatic mutations in KRAS represent a negative predictor of response to anti-EGFR monoclonal antibodies; KRAS mutations also represent an important mechanism of resistance to TKIs in NSCLC. Many large clinical studies are currently investigating the predictive and prognostic value of EGFR mutational status and other candidate biomarkers. We summarize the literature and present an overview of the field of anti-EGFR therapy in NSCLC, focusing on the influence of somatic EGFR mutations on selection of patients for TKI therapy and the influence of EGFR pathway regulation.

Introduction: The combination of Carboplatin and Paclitaxel is considered the standard of care as initial chemotherapy for Advanced Ovarian Cancer (AOC). We compared this regimen with the combination of Cisplatin, Paclitaxel and Doxorubicin. Patients and methods: Patients with AOC were randomised to either six courses of Paclitaxel 175 mg/m(2) plus Carboplatin 7AUC or Paclitaxel at the same dose plus Cisplatin 75 mg/m(2) plus Doxorubicin 40 mg/m(2). Results: Analysis was performed on 451 patients. The treatment groups were well balanced with regard to patient and disease characteristics. Performance status (PS) was better in the anthracycline arm. In terms of severe toxicity, the only significant difference between the two groups was the development of febrile neutropaenia in the anthracycline arm. Overall response rate was similar in both groups. With a median follow-up of 57.5 months, a marginal significance towards improved Progression-Free Survival (PFS) was noted in favour of the anthracycline arm, whilst there was no difference in overall survival. In multivariate analysis the hazard of disease progression at any time was significantly decreased by 25.5% for patients of the anthracycline arm. Conclusion: The combination of Cisplatin, Paclitaxel and Doxorubicin demonstrates a marginal PFS improvement, but no additional survival benefit when compared with the standard Carboplatin/Paclitaxel regimen.

Background After the discovery of somatic mutations in the tyrosine kinase domain (exons 18–24) of the epidermal growth factor receptor (EGFR) correlating with responses of non-small cell lung cancer (NSCLC) to the tyrosine kinase inhibitors (TKIs) gefitinib and erlotinib, there has been increasing interest in utilizing this molecular marker for treatment selection. We aimed to analytically catalogue the mutational spectrum of somatic mutations in EGFR and format a database allowing correlation of specific mutations with clinico-pathologic factors and response to TKIs. Methods A computerized search of MEDLINE (January 1, 2004 to June 30, 2007) was performed to identify articles reporting on NSCLC patients harboring somatic mutations in EGFR. Demographic, clinico-pathologic, mutational, and response data were extracted and tabulated. Results A total of 202 eligible articles were identified. We report data on 12,244 patients with 3381 somatic EGFR mutations. The majority of mutations have been reported on only one occasion (158 of 254, 62.2%), and only nine mutations occur at a rate of ≥1%. L858R and delE746-A750 account for 32.84% and 24.28% of all mutations, respectively; with 50% of mutations being exon 19 deletions or "deletional-insertions." There is a clear association between the presence of mutations and response to TKI. Conclusions We have generated a free access, nonprofit online analytical database of somatic EGFR mutations in NSCLC. Cumulative information will be made available through a routine update of both database tables and associated graphical representations. Direct updates and submissions through the online site (www.somaticmutations-EGFR.org) are encouraged, as are comments and suggestions.

Objective Taxanes, anthracyclines, and platinum compounds represent the chemotherapeutic agents with the greatest activity in metastatic endometrial carcinoma. We administered the combination of paclitaxel, epirubicin and carboplatin to patients with metastatic or recurrent carcinoma of the endometrium to evaluate its activity and to define its toxicity. Methods Sixty-three consecutive patients were treated on an outpatient basis with epirubicin 50 mg/m 2 , followed by paclitaxel 150 mg/m 2 , administered intravenously over a 3-h period. Subsequently, the patients received carboplatin at AUC of 5. The chemotherapy was repeated every 3 weeks with granulocyte colony-stimulating factor (G-CSF) support for a maximum of six courses. Results Response was assessed among 56 eligible patients. Thirty-six (63.2%) patients achieved objective clinical response (95% CI, 50.6–75.7%) including 14 (24.6%) complete and 22 (38.6%) partial responses. The median duration of response was 7.9 months, and the median times to progression and survival for all patients were 7.8 and 13.8 months, respectively. Grade 3 or 4 neutropenia occurred in 9 (15.5%) patients but only 3 episodes of neutropenic fever were encountered. Grade 2 or 3 neurotoxicity was observed in 19% of patients. Two patients died of sudden cardiac death 10 and 14 days after the administration of the first chemotherapy cycle, respectively, but these deaths were not clearly treatment related. Conclusions The combination of paclitaxel, epirubicin and carboplatin with G-CSF support appears active in patients with metastatic or recurrent carcinoma of the endometrium.

The combination of gemcitabine and gefitinib was evaluated in advanced pancreatic cancer. Totally, 53 patients were treated with a 7 week cycle of gemcitabine (1,000 mg/m(2) given weekly) followed by six 4 week cycles of gemcitabine given on days 1, 8 and 15. Gefitinib 250 mg was administered daily. Responses were seen in 6, and stabilization of the disease in 12 patients. The main toxicity was myelotoxicity (92%). The 6-month progression-free survival (PFS) was 30%. Median PFS was 4.1 months and median survival 7.3 months with a 1 year survival rate of 27%. The above combination demonstrated promising activity in advanced pancreatic cancer.

Background:The purpose of this study was to evaluate gemcitabine–carboplatin (GCb) versus single-agent gemcitabine (G) in patients with advanced non-small cell lung cancer (NSCLC) and a performance status (PS) of 2. The primary endpoint was clinical benefit.Patients and Methods:Patients were randomly assigned to either 1250 mg/m2 of G (arm A) or 1250 mg/m2 of G plus carboplatin area under the curve of 3 (arm B). Both treatments were given on days 1 and 14 and were repeated every 28 days for up to four cycles.Results:Among the 90 eligible patients (47 in arm A and 43 in arm B), in arm A, two (4%) had partial responses (95% CI, 0.52%–14.5%) and 10 (21%) had stable disease (95% CI, 10.7%–35.7%). In arm B, six (14%) had partial responses (95% CI, 5.3%–27.9%) and nine (21%) had stable disease (95% CI, 10%–36%) (p = 0.14). No significant difference was found in terms of clinical benefit between the two treatment groups after two cycles of treatment or at the end of chemotherapy. Furthermore, no association was found between clinical benefit and response to treatment (p > 0.05). Median survival was 4.8 months (95% CI, 2.45–7.25) for arm A and 6.7 months (95% CI, 2.47–10.8) for arm B (p = 0.49). Neutropenia (p = 0.007) and thrombocytopenia (p < 0.001) were more common in group B. Nevertheless, no significant differences were found in terms of severe toxicities (p > 0.05 in all cases).Conclusion:No significant difference was found in terms of clinical benefit in patients with NSCLC and PS 2 who received single-agent G or GCb. Nevertheless, GCb caused more toxicity, particularly neutropenia and thrombocytopenia.

Objectives: To develop a hitherto unavailable risk factor model for accurately predicting anemia development in cancer patients before chemotherapy (CT) administration. Methods: 2,070 nonanemic patients from the European Cancer Anaemia Survey (ECAS) with hemoglobin (Hb) ≧12 g/dl at enrollment who received their first CT during ECAS and underwent at least two CT cycles were divided randomly into split half (SH) 1 and SH2 (n = 1,035 each). The model was developed on SH1 using logistic regression to simultaneously evaluate predictive factors, and was validated using SH2 and an additional similar subpopulation of 5,901 ECAS patients. Anemia risk values were assigned to the predictive factors and the sum of the predictive factors gave the total anemia risk score; lower-, higher-, and highest-risk cutoff points of the total anemia risk score were determined. Results: Variables ultimately identified as significant predictive factors for anemia were: lower initial Hb (≤12.9 g/dl in females, and ≤13.4 g/dl in males); having lung or gynecologic cancer versus gastrointestinal (GI)/colorectal cancer; cancer at any other site versus GI/colorectal cancer; treatment with platinum CT, and female gender. Conclusion: Using this evidence-based risk model, nonanemic patients who are at the highest risk of develop ing anemia prior to receiving CT can be identified clinically, allowing appropriate anemia management to be planned.
