Background. High neutrophil to lymphocyte ratio (NLR) has shown to be a predictor of poor outcomes in various malignancies, including pancreatic cancer. Methods. We assessed 70 consecutive pts with histologically confirmed mPC who received chemotherapy with nab-paclitaxel/gemcitabine at two different European oncologic centers between January 2012 and November 2015. Variables assessed for prognostic correlations included age ≥ 66, sex, Karnofsky PS score, primary tumor site, baseline CA19.9 level ≥ 59xULN, 12-week decrease of the CA19.9 level ≥ 50% from baseline, basal bilirubin level, baseline NLR, biliary stent implantation, and liver metastasis. Survival analyses were generated according to the Kaplan-Meier method. Univariate and multivariate analyses were performed by a Cox proportional hazard model. Results. According to NLR values, the patients were divided into two groups: high and low. Low group patients showed a better median PFS (7 months versus 5 months) and median OS (13 months versus 7 months) in respect to high group patients. At multivariate analysis, Karnofsky PS

Endometrial cancer incidence and related mortality are on the rise due to aging demographics. This population often presents with unfavorable features, such as myometrial invasion, non-endometrioid histology, high-grade tumors, worse prognosis, etc. The role of age as an independent prognostic factor is still debated, and screening tools addressing frailty emerge as pivotal in guiding treatment decisions; however, they are still underutilized. Treatment disparities are evident in the case of older patients with endometrial cancer, who frequently receive suboptimal care, hindering their survival. Radiotherapy and minimally invasive surgical approaches could be performed in older patients. Data on chemotherapy and immunotherapy are scarce, but their potential remains promising and data are being gathered by recent trials, contingent on optimal patient selection through geriatric assessments. Overall, we recommend personalized, screening tool-guided approaches, adherence to guideline-recommended treatments, and inclusion of older people in clinical trials to help identify the best course of treatment., Competing Interests: Declaration of Competing Interest Teresa Troiana received honoraria and research funding from Amgen, Novartis Bristol, Pierre Fabre, MSD, and Bayer.

Objective: Preclinical studies have emphasized the potential connection between BRCA specific domains defects and the activity of Poly ADP-ribose polymerase inhibitors (PARPi). Nevertheless, real-world evidence regarding the impact of BRCA domain defects and mutations on PARPi efficacy are limited. The aim of his study was to evaluate the efficacy of PARPi in terms of progression free survival (PFS) according to BRCA domains defects and mutation types., Methods: A retrospective analysis was performed among 79 BRCA mutated patients, diagnosed with advanced High-grade serous ovarian carcinoma (HGSOC) who received first- and second-line platinum- based chemotherapy followed by PARPi maintenance treatment. PFS was evaluated according to BRCA1 [Really Interesting Gene (RING), DNA Binding (DBD), Serine Cluster (SCD), BRCA1 C-terminal (BRCT)] and BRCA2 [RAD-51 Domain (RAD-51 BD), DBD] specific domain defects and mutation types [missense (MS), nonsense (NS), frameshift (FS), splicing (S), or large rearrangements (LR)]., Results: After a median follow-up of 51 months, no significant difference in PFS was observed between the BRCA functional domains or mutation types in the BRCA1 and BRCA2 subgroups. Patients with BRCA2 DBD and RAD51-BD defects had the longest (39.8 months) and shortest (24.1 months) median PFS, respectively (p = 0.11). Additionally, patients with BRCA1 DBD defects had the greatest benefit (median PFS = 33.8 months) while those with BRCA1 RING domain mutations experienced the worst outcome (median PFS = 30.9 months (p = 0.43)., Conclusion: The efficacy of maintenance treatment with PARPi is independent by BRCA domain defects or mutation types. Patients DBD domain defects experienced numerically longer median PFS compared to those with other BRCA1/2 alterations., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Buonaiuto, Neola, Caltavituro, Longobardi, Mangiacotti, Cefaliello, Lamia, Pepe, Ventriglia, Malapelle, Troncone, Giuliano, Arpino, Pignata and De Angelis.)

Cervical cancer (CC) is the second most commonly diagnosed cancer and the third leading cause of cancer death among females. The options of treatment for recurrent/advanced CC are limited and patients experiencing recurrence after first line platinum-based chemotherapy have a poor prognosis. In this context, immune checkpoint inhibitors (ICI)s antagonizing PD-1 and programmed death-ligand 1 (PD-L1) have profoundly changed the treatment scenario and outcomes in CC in the first or subsequent lines both as monotherapies or in combination with chemotherapy or other ICIs. Herein, we report the clinical case of a 74-year-old woman with metastatic CC with negative tumor PD-L1 expression who having disease progression after first-line of systemic treatment with platinum, thus undergoing to anti-PD-1 namely cemiplimab. The patient achieved a surprising, fast and complete metabolic response to cemiplimab immediately discontinued after only two cycles due to the onset of rare and severe immune-related adverse events (irAE)s such cardiovascular toxicity and hypertransaminasemia. Despite this, thirteen months later, the patient remains disease-free despite cemiplimab was withdrawn., Competing Interests: SP received honoraria from MSD, Pfizer, AZ, Roche, Clovis, and GSK.

Non-clear cell renal cell carcinoma (nccRCC) is a heterogeneous group representing 15-30% of renal tumors. They are mostly excluded from immunotherapy trials due to their rarity and worse prognosis. This, alongside nccRCC misdiagnosis/misclassification, lack of immune-biomarker expression rate data, lack of homogeneous data reporting, the retrospective nature of many studies, small sample sizes, and the fact that high-grade evidence only stems from trials mostly addressing the clear cell subtype, result in poorly defined treatments. We thus reviewed available data from several clinical trials, retrospective studies, and meta-analyses on immunotherapy responses and their correlation with histological subtypes and prognostic biomarkers. The papillary and unclassified subtypes are the best candidate for immunotherapy, showing response rates up to ∼35%. Chromophobe cancers, on the other end, have mostly null response rates. Cancers with sarcomatoid features respond very well to immunotherapy, regardless of their histology. Available data for translocation, medullary, collecting duct, and other nccRCCs are inconclusive. Regarding PD-L1, its expression correlates with better responses, but its prognostic value remains to be determined due to small sample sizes hindering direct statistical comparisons. It is necessary to involve a larger number of nccRCC patients and centers in clinical trials and report tumor response rates and PD-(L)1 and other markers' expression rates divided by nccRCC subtypes and not just for the whole cohorts. This will allow us to collect more robust data to best identify patients who can benefit from immunotherapy and ultimately define the standard of treatment.

Objective: Correlation between BRCA1/ 2 ( BRCA ) pathogenic variants and the response to poly (ADP-ribose) polymerase inhibitors (PARPi) has been recognized in patients with ovarian cancer. Moreover, data on the clinical implications of variants of unknown significance are lacking. The aim of this study was to evaluate differences in survival outcomes in patients with BRCA variants of unknown significance, mutated, and wild type relapsed ovarian cancer treated with PARPi., Methods: Patients with ovarian cancer whose somatic BRCA testing was available and who were receiving PARPi as maintenance treatment at the first recurrence between January 2014 and January 2021 were included in the present study and analyzed. Patients were divided into three groups according to BRCA mutational status (variant of unknown significance, mutated, and wild type). Progression-free survival was assessed in each study group., Results: Of 67 patients identified, 20 (29.9%), 24 (35.8%), and 23 (34.3%) had BRCA variant of unknown significance, mutated, and wild type, respectively. Patients received PARPi as maintenance treatment at the time of the first relapse after a complete response or partial response to platinum-based chemotherapy without differences in the previous platinum-free interval among the analyzed groups. The median progression-free survival of patients with BRCA mutation was significantly longer than for those with BRCA wild type or variant of unknown significance (not reached vs 4 months vs 7 months, respectively; p<0.001). Additionally, no significant difference was found between patients with BRCA wild type and BRCA variant of unknown significance (p=0.50)., Conclusion: Our study suggests that carriers of BRCA variant of unknown significance have survival outcomes comparable to patients with BRCA wild type and shorter progression-free survival than women harboring BRCA pathogenic variants., Competing Interests: Competing interests: CM reports consultant/advisory board for Clovis, Pharmamar, GSK, AstraZeneca, Arquer Diagnostic and travel accommodation from PharmaMar and Roche.

Background: PARP inhibitors (PARPi) have revolutionized the management of high-grade epithelial ovarian cancer (HGOC) treatment. However, a significant number of patients relapse or progress under PARPi, leading to the introduction of a new line of systemic therapy such as chemotherapy. In patients with a limited number of metastatic sites at progression, -referred to as an oligometastatic progression- a potential indication for local therapy followed by re-introduction or continuation of PARPi treatment rather than initiating a new line of chemotherapy could be proposed. However, the impact of such strategies on progression free survival (PFS) in these patients remains unknown., Methods: This international multicenter retrospective study evaluated the efficacy of PARPi continuation or re-introduction in patients with HGOC after local treatment for oligometastatic progression. The main objective was to assess PFS under PARPi after local therapy (PFS post-LT). Secondary objectives included safety and overall survival (OS)., Results: 74 patients were identified in 20 centers between April 2020 and November 2021. 65% of patients were BRCA mutated and 92% had received ≥2 lines of prior systemic chemotherapy before the initial introduction of PARPi. Main progression sites were lymph nodes (42%), peritoneum (27%), liver (16%), other visceral (16%) and abdominal wall (4%). Local therapies included radiotherapy (45%), surgery (43%), both (7%), percutaneous thermal ablation (4%) or chemoembolization (1%). Median PFS post-LT was 11.5 months [95% CI 7.4; 17.2]. After a median follow up of 14.8 months, 6 patients (8.1%) discontinued PARPi due to toxicity. The 1-year overall survival rate was 90.7% [95% CI 79.1; 96.0]., Conclusions: With close to one year without progression or introduction of a new line of systemic therapy, this study reports the feasibility and potential benefit of this original strategy in patients with oligometastatic progression under PARPi., (Copyright © 2023 Elsevier Inc.

Objective: The aim of the present analysis was to explore the efficacy of Bevacizumab (Bev) on survival outcome in advanced low grade serous ovarian cancer (LGSOC) both in first line and in recurrent setting., Methods: In retrospective observational multicenter study, we described the outcome of LGSOC patients enrolled in the MITO 22 study and treated with chemotherapy (CT) with or without Bev. Patients receiving Bev in first-line or in recurrence were considered and compared with patients receiving CT alone (stage III and IV in first line; platinum based-CT in second line). Descriptive and survival analyses were performed for each group., Results: Out of 128 patients included in MITO 22, 46 LGSOC patients receiving Bev in first line setting or at the time of first recurrence were identified. In first line, 30 patients received Bev + CT and 65 CT alone and the median PFS were 47.86 months (95% CI: 31.48 - NR) and 22.63 months (95% CI 15-39.24) (p-value 0.0392), respectively. In the recurrent setting, 16 patients who received Bev + CT were compared to 33 women treated with platinum-based CT alone. Median PFS were 37.1 months (95% CI: 13.42-40.56) and 11.22 months (95% CI: 8.26-15.63) (p-value 0.013), respectively., Conclusions: Our study suggests that Bev might be effective in LGSOC both at diagnosis and at the time of relapse. These data warrants further studies., Competing Interests: Declaration of Competing Interest CM reports consultant/advisory board for Clovis, Pharmamar, GSK, Astrazeneca, Arquer diagnostic and travel accommodation from Pharmamar and Roche.

Endometrial cancer (EC) is the most common gynecologic cancer in Europe and its prevalence is increasing. EC includes a biological and clinical heterogeneous group of tumors, usually classified as type I (endometrioid) or type II (non-endometrioid) based on the histopathological characteristics. In 2013, a new molecular classification was proposed by The Cancer Genome Atlas (TCGA) based on the comprehensive molecular profiling of EC. Several molecular somatic alterations have been described in development and progression of EC. Using these molecular features, EC was reclassified into four subgroups: POLE ultra-mutated, MSI hypermutated, copy-number low, and copy-number high that correlate with the prognosis. To this regard, it is widely reported that EC has more frequent mutations in the phosphatidylinositol 3-kinase (PI3K) pathway signaling than any other tumor. PIK3CA is the main significant mutated gene after PTEN alterations. Overall, over 90% of endometrioid tumors have activating PI3K molecular alterations that suggests its critical role in the EC pathogenesis. Thus, the dysregulation of PI3K pathway represents an attractive target in EC treatment. Herein, we report a radiological and clinically meaningful response to a selective PIK3 inhibitor in a patient with extensively pre-treated advanced endometrioid EC harboring a somatic activating PIK3CA hotspot mutation. These evidences provide the rational for translational strategies of the PI3K inhibition and could support the clinical usefulness of PIK3CA genotyping in advanced EC. To our knowledge, this is the first clinical case of PIK3CA -mutated EC successfully treated with alpelisib., Competing Interests: SP received honoraria from MSD, Pfizer, AZ, Roche, Clovis, and GSK.

Immunotherapy is acquiring a primary role in treating endometrial cancer (EC) with a relevant benefit for many patients. Regardless, patients progressing during immunotherapy or those who are resistant represent an unmet need. The mechanisms of immune resistance and escape need to be better investigated. Here, we review the major mechanisms of immune escape activated by the indolamine 2,3-dioxygenase 1 (IDO1) pathway in EC and focus on potential therapeutic strategies based on IDO1 signaling pathway control. IDO1 catalyzes the first rate-limiting step of the so-called "kynurenine (Kyn) pathway", which converts the essential amino acid l-tryptophan into the immunosuppressive metabolite l-kynurenine. Functionally, IDO1 has played a pivotal role in cancer immune escape by catalyzing the initial step of the Kyn pathway. The overexpression of IDO1 is also associated with poor prognosis in EC. These findings can lead to advantages in immunotherapy-based approaches as a rationale for overcoming the immune escape. Indeed, besides immune checkpoints, other mechanisms, including the IDO enzymes, contribute to the EC progression due to the immunosuppression induced by the tumor milieu. On the other hand, the IDO1 enzyme has recently emerged as both a promising therapeutic target and an unfavorable prognostic biomarker. This evidence provides the basis for translational strategies of immune combination, whereas IDO1 expression would serve as a potential prognostic biomarker in metastatic EC., Competing Interests: SP received honoraria from MSD, Pfizer, AZ, Roche, Clovis, and GSK.

Background: Penile cancer (PC) is an extremely rare malignancy, and the patients at advanced stages have currently limited treatment options with disappointing results. Immune checkpoint inhibitors anti-programmed cell death 1 (PD-1)/programmed cell death ligand 1 (PD-L1) are currently changing the treatment of several tumors. Furthermore, the microsatellite instability (MSI) and the deficient mismatch repair system (dMMR) proteins represent predictive biomarkers for response to immune checkpoint therapy. Until present, few data have been reported related to PD-L1 expression and MSI in PC. The main aim of our study was the evaluation of PD-L1 expression in tumor cells (TCs) and tumor-infiltrating lymphocytes (TILs) in immune cells and the analysis of dMMR/MSI status in a large series of PCs., Methods: A series of 72 PC, including 65 usual squamous cell carcinoma (USCC), 1 verrucous, 4 basaloid, 1 warty, and 1 mixed (warty-basaloid), was collected. Immunohistochemistry (IHC) was performed to assess PD-L1 expression using two different anti-PD-L1 antibodies (clone SP263 and SP142 Ventana) and MMR proteins expression using anti-MLH1, anti-PMS2, anti-MSH2, and anti-MSH6 antibodies. PCR analysis was performed for the detection of MSI status., Results: Of the 72 PC cases analyzed by IHC, 45 (62.5%) cases were TC positive and 57 (79%) cases were combined positive score (CPS) using PDL1 SP263. In our cohort, TILs were present in 62 out of 72 cases (86.1%), 47 (75.8%) out of 62 cases showed positivity to PDL1 clone SP142. In our series, 59 cases (82%) had pMMR, 12 cases (16.7%) had lo-paMMR, and only 1 case (1.3%) had MMR. PCR results showed that only one case lo-paMMR was MSI-H, and the case dMMR by IHC not confirmed MSI status., Conclusion: Our findings showed that PD-L1 expression and MSI status represent frequent biological events in this tumor suggesting a rationale for a new frontier in the treatment of patients with PC based on the immune checkpoint inhibitors., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Oligometastatic prostate cancer is an intermediate state between localized disease and widespread metastasis. Its biological and clinical peculiarities are still to be elucidated. New imaging techniques contribute to the detection of patients with oligometastatic disease. PET/CT scanning with prostate-specific membrane antigen can improve the selection of men with true early, low-volume oligometastatic disease, who are candidates for metastasis-directed therapy. Clinical studies demonstrated that androgen deprivation therapy can be delayed in oligometastatic patients with a low tumor burden, although no survival benefit has been demonstrated at present. This article presents available evidence on the treatment strategies for oligometastatic prostate cancer.

Background: Chemotherapy with carboplatin, paclitaxel, and bevacizumab is the standard therapy for patients with advanced stage ovarian cancer wild-type BRCA after primary surgery. The most frequent side effects of bevacizumab in this setting are hypertension, thrombosis, hemorrhage, and proteinuria, while arthralgia has been poorly described., Objective: To examine the incidence, duration, and reversibility of arthralgia., Patients and Methods: A retrospective analysis was performed to describe the occurrence and outcome of arthralgia in 114 patients with advanced ovarian cancer, given first-line treatment with a combination of carboplatin, paclitaxel, and bevacizumab. Statistical analysis was performed to investigate a possible prognostic role of arthralgia, with progression-free survival as endpoint., Results: 47 of 114 patients (41%) developed arthralgia during therapy. All patients had grade 1 or grade 2 arthralgia. Toxicity persisted after the end of bevacizumab in 17/47 patients (36%). Median progression-free survival for patients without arthralgia was 18 months (95% CI 14 to 24) compared with 29 months (95% CI 21 to not reached) for patients experiencing arthralgia (p=0.03). In order to avoid possible biases related to treatment duration, a multivariable Cox proportional hazards model including toxicity as a time dependent variable and age, stage, and residual disease after primary surgery was performed. In this model no variable showed a statistically significant association with progression-free survival., Conclusion: A high incidence of arthralgia (41%) was found and although rogression-free survival was worse for those patients who developed arthralgia, this was not maintained on multivariate analysis. Guidelines for treatment of this adverse event are needed., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2021. No commercial re-use. See rights and permissions.

Background: The coronavirus disease 2019 (COVID-19) pandemic has overwhelmed the health systems worldwide. Data regarding the impact of COVID-19 on cancer patients (CPs) undergoing or candidate for immune checkpoint inhibitors (ICIs) are lacking. We depicted the practice and adaptations in the management of patients with solid tumors eligible or receiving ICIs during the COVID-19 pandemic, with a special focus on Campania region., Methods: This survey (25 questions), promoted by the young section of SCITO (Società Campana di ImmunoTerapia Oncologica) Group, was circulated among Italian young oncologists practicing in regions variously affected by the pandemic: high (group 1), medium (group 2) and low (group 3) prevalence of SARS-CoV-2-positive patients. For Campania region, the physician responders were split into those working in cancer centers (CC), university hospitals (UH) and general hospitals (GH). Percentages of agreement, among High (H) versus Medium (M) and versus Low (L) group for Italy and among CC, UH and GH for Campania region, were compared by using Fisher's exact tests for dichotomous answers and χ 2 test for trends relative to the questions with 3 or more options., Results: This is the first Italian study to investigate the COVID-19 impact on cancer immunotherapy, unique in its type and very clear in the results. The COVID-19 pandemic seemed not to affect the standard practice in the prescription and delivery of ICIs in Italy. Telemedicine was widely used. There was high consensus to interrupt immunotherapy in SARS-CoV-2-positive patients and to adopt ICIs with longer schedule interval. The majority of the responders tended not to delay the start of ICIs; there were no changes in supportive treatments, but some of the physicians opted for delaying surgeries (if part of patients' planned treatment approach). The results from responders in Campania did not differ significantly from the national ones., Conclusion: Our study highlights the efforts of Italian oncologists to maintain high standards of care for CPs treated with ICIs, regardless the regional prevalence of COVID-19, suggesting the adoption of similar solutions. Research on patients treated with ICIs and experiencing COVID-19 will clarify the safety profile to continue the treatments, thus informing on the most appropriate clinical conducts., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Background: Nab-paclitaxel plus gemcitabine represents one of the standard regimens for first line treatment of metastatic pancreatic cancer (mPC). Few data are available on nab-paclitaxel plus gemcitabine in geriatric population. Our study aims to show whether this schedule can be feasible in the elderly as first-line treatment for mPC., Methods: We retrospectively analyzed the data of 64 mPC patients (≥65 years old) treated according to the MPACT schedule., Results: Median age was 69.5 years (range, 65-80 years); after a median of 5 cycles administered (range, 1-12), the most common adverse events (AEs) were grade 2 alopecia (46.9%), anemia (17.2%) and hypertransaminasemia (10.9%); all grades neutropenia occurred in 20.3% of pts. Global incidence of grade 3 and 4 toxicities were 26.5% and 0%, respectively, and no patients stopped treatment due to unacceptable toxicity. Stable disease (SD) was observed in 31.2% of patients, with a disease control rate (DCR) and overall response rate of 57.8% and 26.6%, respectively. After a median follow-up of 18 months, median progression free survival (PFS) was 8 months (95% CI: 6.3-9.6) and median OS was 12.0 months (95% CI: 8.4-15.6). The univariate analysis for overall survival (OS) showed that only ECOG performance status was an independent prognostic factor for survival., Conclusions: Nab-paclitaxel plus gemcitabine schedule is feasible and effective in the "daily clinical practice" geriatric population., Competing Interests: Conflicts of Interest: A Petrillo: Honoraria from Lilly.

Background: Neoangiogenesis has proven to be a relevant pathogenetic mechanism in gastric cancer (GC) and lymphatic spread represents an important well-known prognostic factor. Vascular endothelial growth factor C (VEGF-C) plays a key role in lymphangiogenesis and its blood levels in GC patients are easily measurable. This analysis aimed to investigate the prognostic role of preoperative VEGF-C blood levels., Methods: VEGF-C serum levels were determined by enzyme-linked immunoadsorbent assay (ELISA) in 186 patients observed at our institution from January 2004 until December 2009 and 82 healthy subjects. Statistical analyses were performed using SPSS 21.0., Results: VEGF-C levels were significantly higher in GC patients (median: 287.4 pg/mL; range, 76.2-865.2 pg/mL) than in the control group (median VEGF-C: 31 pg/mL; range, 12-97 pg/mL). A significant correlation between VEGF-C levels, T, N and tumor stage has been described. The median overall survival (OS) was statistically significantly higher in pts with low serum VEGF-C levels [median: not reached (NR) vs. 26 months; P<0.0001]. Higher preoperative VEGF-C levels correlated also with earlier disease relapse and poor disease-free survival (DFS) (median NR in each subgroup, P=0.005). Furthermore, high VEGF-C levels [hazard ratio (HR) =2.7; P=0.018] and tumor grading (HR =0.44; P=0.007) were independent prognostic factors for OS at multivariate analysis., Conclusions: Our study showed that increased VEGF-C levels are significantly associated with advanced regional lymph node involvement and poor OS and DFS in pts with resected GC paving the way to a possible application as prognostic factor in the clinical practice., Competing Interests: Conflicts of Interest: F Ciardiello: Advisory Boards: Roche, Amgen, Merck, Pfizer, Sanofi, Bayer, Servier, BMS, Celgene, Lilly; Institutional Research Grants: Bayer, Roche, Merck, Amgen, AstraZeneca, Takeda; F De Vita: Advisory Boards: Roche, Amgen, Celgene, Lilly; M Orditura: Honoraria from Italfarmaco, EISAI, epionpharma, Roche; A Petrillo: honoraria from Lilly.

Aim: Systemic inflammatory response affects survival of gastric cancer (GC) patients. This study was carried out to create a prognostic inflammatory-based score to predict survival in metastatic GC (mGC) before first-line chemotherapy., Materials & Methods: We studied the prognostic value of neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio in 151 patients with mGC at the diagnosis., Results: Median overall survival (OS) was significantly lower in patients with high NLR. Performance status 1-2 according to the Eastern Cooperative Oncology Group scale and NLR were predictors of shorter OS at multivariate analysis. Based on these results, we defined a prognostic OS score, showing a better median OS in favorable risk group., Conclusion: Elevated pretreatment NLR and Eastern Cooperative Oncology Group are independent predictors of shorter OS in mGC patients before first-line chemotherapy.

Purpose of Review: Triple-negative breast cancer (TNBC) accounts for 15-20% of diagnosed breast tumours, with higher incidence in young and African-American women, and it is frequently associated with BRCA germline mutations. Chemotherapy is the only well-established therapeutic option in both early- and advanced-stages of the disease. TNBC tumours relapse earlier after standard anthracycline- and/or taxane-based chemotherapy treatments, generally within 1-3 years after the diagnosis, and often develop visceral metastases, representing the subtype with a worse prognosis among all breast cancers. In the present review, we will provide an updated overview of the available results of recent clinical trials for this disease and we will describe the implications of the known molecular pathways representing novel targets for development of future therapies for TNBC patients., Recent Findings: Over the past decade, the advent of gene expression micro-array technology has led to the identification of different actionable targets including various genomic alterations, androgen receptor, PARP, PI3K, VEGF and other proteins of the angiogenic pathway. Thus, novel targeted drugs have been tested in clinical trials reporting promising results in specific TNBC molecular subgroups. Although cytotoxic chemotherapy remains the mainstay of treatment for TNBC patients, the identification of novel 'drugable' targets and pathways for developing personalized treatments represents a promising investigational approach in the management of the TNBC subtype.

Background: The variability in progression-free survival (PFS) and overall survival (OS) among patients with epithelial ovarian cancer (EOC) makes it difficult to reliably predict outcomes. A predictive biomarker of bevacizumab efficacy as first-line therapy in EOC is still lacking., Objective: The MITO group conducted a multicenter, retrospective study (MITO 24) to investigate the role of inflammatory indexes as prognostic factors and predictors of treatment efficacy in FIGO stage III-IV EOC patients treated with first-line chemotherapy alone or in combination with bevacizumab., Patients and Methods: Of the 375 patients recruited, 301 received chemotherapy alone and 74 received chemotherapy with bevacizumab. The pre-treatment neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic immune inflammation index (SII) were evaluated to identify a potential correlation with PFS and OS in both the overall population and the two treatment arms., Results: In the overall population, the PFS and OS were significantly longer in patients with low inflammatory indexes (p < 0.0001). In multivariate analyses, the NLR was significantly associated with OS (p = 0.016), and the PLR was significantly associated with PFS (p = 0.024). Inflammatory indexes were significantly correlated with patient prognosis in the chemotherapy-alone group (p < 0.0001). Patients in the chemotherapy with bevacizumab group with a high NLR had a higher PFS and OS (p = 0.026 and p = 0.029, respectively) than those in the chemotherapy-alone group. Conversely, PFS and OS were significantly poorer in patients with a high SII (p = 0.024 and p = 0.017, respectively)., Conclusion: Our results suggest that bevacizumab improves clinical outcome in patients with a high NLR but may be detrimental in those with a high SII.

In patients with recurrent ovarian cancer, the choice of second-line therapy is complex. Several factors have to be considered, such as platinum-free interval (PFI), residual toxicity from the previous treatments, BRCA1/2 gene mutation status. Trebectedin is a minor groove DNA binder derived from a marine organism that has shown efficacy in different settings in ovarian cancer therapy. It has been approved in the treatment of partially platinum sensitive (PPS) (PFI between 6 and 12 months) relapsed ovarian cancer according to the statistically significant progression-free survival (7.3 versus 5.8 months) and overall survival (22.2 versus 18.9 months) benefit compared with single-agent pegylated liposomal doxorubicin (PLD) in the OVA 301 phase III trial. This drug has been shown to prolong the time to first subsequent treatment and improve the efficacy of further platinum-based chemotherapy. The role of trabectedin/PLD followed by platinum combination compared with the reverse sequence in PPS is actually in evaluation in the INOVATYON phase III study, which will clarify the best sequence to be adopted in this setting. Trabectedin has been shown to be active in patient carriers of BRCA mutations, probably for its mechanism of action directly affecting DNA and it is actually tested as a single agent in some phase III trials in BRCA mutated and BRCAness ovarian cancer patients. Trabectedin is also active on the immune system. There is, therefore, the rational for new trials of a combination with immune checkpoint inhibitors., (Copyright © 2018 The Royal College of Radiologists. All rights reserved.)

Background: Ramucirumab-alone or combined with paclitaxel-represents one of the main options for patients failing first-line treatment for advanced gastric cancer., Objective: The RAMoss study aimed to evaluate the safety and efficacy profile of ramucirumab in the "real-life setting"., Patients and Methods: Patients from 25 Italian hospitals started therapy consisting of ramucirumab 8 mg/kg i.v. d1,15q28 with or without paclitaxel 80 mg/m 2 i.v. d1,8,15q28. The primary endpoint was safety, and secondary endpoints were overall response rate (ORR), progression-free survival (PFS), and overall survival (OS)., Results: One hundred sixty-seven patients with disease progression on first-line therapy received ramucirumab as monotherapy (10%) or combined with paclitaxel (90%). Median treatment duration was 4 months (1-17 months). Global incidence of grade (G) 3-4 toxicity was 9.6%, and for neutropenia 5.4%; treatment was discontinued due to toxicity in 3% of patients. The most frequent adverse events (AE) were G1-2 fatigue (27.5%), G1-2 neuropathy (26.3%), and G1-2 neutropenia (14.9%). ORR was 20.2%. Stable disease was observed in 39.2% of patients, with a disease control rate of 59.4%. With a median follow-up of 11 months, median PFS was 4.3 months (95% confidence interval [CI] 4.1-4.7), whereas median OS was 8.0 months (95% CI: 7.09-8.9). In a multivariate analysis, ECOG performance status <1 or ≥1 (HR 1.13, 95% CI 1.0-1.27, p = 0.04) and the presence versus absence of peritoneal metastases (HR 1.57, 95% CI 1.63-2.39, p = 0.03) were independent poor prognostic factors., Conclusions: These "real-life" efficacy data on ramucirumab treatment are in line with previous randomized trials. Ramucirumab is well tolerated in daily clinical practice.

The tumors of the female genital tract represent a leading cause of morbidity and mortality among women worldwide. Substantial progresses have been made in ovarian cancer, with the increasing knowledge about BRCA mutated tumors and the recent development of PARP inhibitors, and in cervical cancer, thanks to extensive screening and widespread of vaccination against Human Papilloma Virus. Nevertheless many needs remain unmet, advanced stage diseases are still incurable and cervical and endometrial carcinoma, as well as platinum-resistant ovarian carcinoma, can certainly be classifiable among the cancers with poor sensitivity to conventional chemotherapy. Immunotherapy, including a number of approaches, checkpoint inhibitors, adoptive cellular transfer, vaccines, has experienced a remarkable growth in the last few years and it is already an available option in melanoma, lung and renal malignancies. We reviewed the main findings about the immune microenvironment in ovarian, endometrial and cervical cancer with a special focus on the clinical data, the therapeutic implications and the most promising novel agents., (Copyright © 2017 Elsevier Ltd.

Background: Pancreatic adenocarcinoma is an aggressive disease with poor prognosis. In a randomized phase III trial, combination of Nab-paclitaxel (Nab-P) plus gemcitabine showed superior activity and efficacy in first-line treatment compared with gemcitabine alone., Methods: Nab-P is not dispensed in Italy; however, we obtained this drug from our Ethics Committee for compassionate use. The aim of this study was to evaluate the efficacy and safety profile of this Nab-P and gemcitabine combination in a cohort of patients treated outside clinical trials. From January 2012 to May 2014, we included 41 patients with advanced pancreatic adenocarcinoma receiving combination of 125 mg/m(2) Nab-P and 1 g/m(2) gemcitabine on days 1, 8 and 15 of a 28-day cycle, as first-line treatment. Median age of patients was 67 (range 41-77) years, and 11 patients were aged ≥70 years., Results: Eastern Co-operative Oncology Group performance status was 0 or 1 in 32 patients (78 %) and 2 in nine patients (22 %). Primary tumor was located in the pancreatic head or body/tail in 24 (58.5 %) and 17 (41.5 %) patients, respectively, and nine patients had received biliary stent implantation before starting chemotherapy. Median carbohydrate antigen 19-9 level was 469 U/l (range 17.4-61546 U/l) and 29 patients (70.7 %) had referred pain at the time of diagnosis. Patients received a median six cycles (range 1-14) of treatment. Overall response rate was 36.6 %; median progression-free survival was 6.7 months [(95 % confidence interval (CI) 5.966-8.034), and median overall survival was 10 months (95 % CI 7.864-12.136). Treatment was well tolerated. No grade 4 toxicity was reported. Grade 3 toxicity included neutropenia in 10 patients (24.3 %), thrombocytopenia in five (12 %), anemia in three (7.3 %), diarrhea in four (9.7 %), nausea and vomiting in two (4.9 %), and fatigue in six (14.6 %). Finally, pain control was achieved in 24 of 29 patients (82.3 %) with a performance status improvement of 10 % according to the Karnofsky scale., Conclusions: Our results confirm that combination of gemcitabine plus Nab-P is effective both in terms of overall response rate, progression-free survival and overall survival, with a good safety profile.

Pancreatic neuroendocrine tumors (pNETs) represent about 7% of all NETs, 8.7% of gastroenteropancreatic NETs (GEP-NETs) and 1-2% of all pancreatic neoplasms. In the last two decades, the increased diagnosis of pNETs has generated great interest and the development of different classifications, grading and staging systems. Recently, several trials were performed in order to improve the knowledge of biomarkers and imaging and to provide an early diagnosis, but their role is still under debate. Nowadays, surgery represents the only curative approach for pNETs. Approximately 90% of pNETs are silent and non-functional; therefore, most patients are diagnosed in late stage and present metastatic (60%) or locally unresectable advanced disease (21%) with a poor prognosis. Not many therapeutic options are available for pNETs, with different treatments for G1-G2 and G3 tumors, because these diseases are still rare and trials are made up of few series of patients. At present, medical treatments is controversial. On these bases, we believe that a multidisciplinary team composed of surgeons, oncologists, endocrinologists, radiation oncologists, radiologists, pathologists and medicals nuclear is required. This paper presents a review of present state-of-the-art in the field of pNETs., (Copyright © 2016. Published by Elsevier Ltd.)

Objective: To assess the correlation between presurgery neutrophil to lymphocyte ratio (NLR) and distant metastasis-free survival (DMFS) in patients with early breast cancer., Design: Retrospective analysis., Participants: 300 Caucasian patients with early (T1-2, N0-1, non-metastatic) breast cancer who were followed from July 1999 to June 2015 at our Institution., Main Outcome Measures: Distant metastasis-free survival (DMFS)., Results: Of whole populations (300 patients), 134 and 166 patients were grouped as low and high NLR, respectively, on the basis of NLR value of 1.97, as established by receiver operating characteristic (ROC) curve analysis (area under curve (AUC)=0.625, p=0.0160). The DMFS rates for 1, 3, 6, 9, 12 and 15 years were better in low NLR patients (100%, 98.9%, 91.7%, 82.7%, 82.7%, 82.7%, respectively), than in high NLR patients (99.4%, 94.3%, 84.5%, 69.2%, 66.0%, 51.4%, respectively), with a statistically significant association. On multivariate analysis, premenopausal status (HR=2.78, 95% CI 1.36 to 5.67, p=0.0049), N1 stage (HR=2.31, 95% CI 1.16 to 4.60, p=0.0167) and a high NLR value (HR=2.64, 95% CI 1.22 to 5.638, p=0.0133) were shown to be independent prognostic factors related to poor recurrence rate. To avoid risk of confounding bias, a propensity score-matched analysis was performed and multivariate analysis according to the Cox model confirmed premenopausal status (HR=2.94, 95% CI 1.25 to 6.93, p=0.0136), N1 stage (HR=2.77, 95% CI 1.25 to 6.12, p=0.0117) and high NLR values (HR=2.52, 95% CI 1.11 to 5.73, p=0.0271), as independent prognostic variables of worse outcome., Conclusions: This is the first study, to our knowledge, to show a significant correlation between high NLR and worse prognosis in Caucasian patients with early breast cancer by means of propensity score-matched analysis. Further well designed prospective trials with a large sample size are needed to verify our findings and to justify introducing NLR assessment in clinical practice for prediction of cancer recurrence., Competing Interests: Conflicts of Interest: None declared.

Bone metastasis is an uncommon event in advanced gastric cancer patients and bone metastases are rarely detected as isolated lesions. However, eleven years after treatment for locally advanced gastric cancer, including total gastrectomy followed by adjuvant chemotherapy, a 49-year-old female was admitted to the IX Division of General Surgery of the Second University of Naples (Naples, Italy) exhibiting severe progressive neurological symptoms. Magnetic resonance imaging indicated vertebral abnormalities, with evidence of marrow infiltration in several vertebral bodies; however, a contrast-enhanced computed tomography scan did not detect disease progression to other sites. Biopsy of the soft tissue at the level of the second lumbar vertebra (L2) revealed a metastatic lesion derived from gastric mucinous adenocarcinoma. The patient was initially treated with radiotherapy directed to the L2-L4 vertebral bodies to control the pain. Subsequently, systemic chemotherapy according to a FOLFOX-4 (leucovorin, fluorouracil and oxaliplatin) regimen commenced. However, after eight cycles, pulmonary progression of the disease occurred. Thus, palliative care was administered and the patient succumbed one month later. The late relapse of gastric cancer in the current patient may be associated with the theory of tumour dormancy.

Gastric cancer is the fourth most common malignant neoplasm and the second leading cause of death for cancer in Western countries with more than 20000 new cases yearly diagnosed in the United States. Surgery represents the main approach for this disease but, notwithstanding the advances in surgical techniques, we observed a minimal improvement in terms of overall survival with a significant increasing of relapsing disease rates. Despite the development of new drugs has significantly improved the effectiveness of chemotherapy, the prognosis of patients with unresectable or metastatic gastric adenocarcinoma remains poor. Recently, several molecular target agents have been investigated; in particular, trastuzumab represents the first target molecule showing improvements in overall survival in human epithelial growth factor 2-positive gastric cancer patients. New molecules targeting vascular epithelial growth factor, mammalian target of rapamycin, and anti hepatocyte growth factor-c-Met pathway are also under investigation, with interesting results. Anyway, it seems necessary to select more accurately the population to treat with new agents by the identification of new biomarkers in order to optimize the results. In this paper we review the actual "scenario" of targeted treatments, also focusing on the new agents in development for gastric cancer and gastro-esophageal carcinoma, discussing their efficacy and potential applications in clinical practice.

The authors focused on the current surgical treatment of resectable gastric cancer, and significance of peri- and post-operative chemo or chemoradiation. Gastric cancer is the 4(th) most commonly diagnosed cancer and the second leading cause of cancer death worldwide. Surgery remains the only curative therapy, while perioperative and adjuvant chemotherapy, as well as chemoradiation, can improve outcome of resectable gastric cancer with extended lymph node dissection. More than half of radically resected gastric cancer patients relapse locally or with distant metastases, or receive the diagnosis of gastric cancer when tumor is disseminated; therefore, median survival rarely exceeds 12 mo, and 5-years survival is less than 10%. Cisplatin and fluoropyrimidine-based chemotherapy, with addition of trastuzumab in human epidermal growth factor receptor 2 positive patients, is the widely used treatment in stage IV patients fit for chemotherapy. Recent evidence supports the use of second-line chemotherapy after progression in patients with good performance status.

Increased insulin-like growth factor (igf) signalling has been observed in breast cancer, including endocrine-responsive cancers, and has been linked to disease progression and recurrence. In particular, igf-1 has the ability to induce and promote lymphangiogenesis through the induction of vascular endothelial growth factor C (vegfc). In the present study, we analyzed serum and tumour samples from 60 patients with endocrine-positive breast cancer to determine the expression and the possible relationship of circulating igf-1, igf binding protein 3 (igfbp3), and vegfc with the presence of lymphatic metastasis and other immunohistochemical parameters. The analysis revealed a clear and significant correlation between high basal levels of igf-1, igfbp3, and vegfc and lymph node metastasis in endocrine-responsive breast cancer. In addition, expression of those molecules was significantly higher in breast cancer patients than in healthy control subjects. Those findings may enable more accurate prediction of prognosis in patients with breast cancer.
