RESUMEN
Registrative trials recommended the use of upfront chemotherapy in high-volume metastatic prostate cancer. We reported survival outcomes of patients with high-volume mCRPC treated with ARTA in a chemo-naïve setting compared to patients treated with chemotherapy as first-line from a longitudinal real-life multicenter series. We retrospectively collected data on mCRPC patients treated at six centers. The dataset was queried for high-volume disease (defined as more than 6 bone lesions or bulky nodes ≥ 5 cm). We compared the main clinical features of chemo-naïve versus chemo-treated patients. The Mann-Whitney U test and Chi-squared test were used to compare continuous and categorial variables, respectively. The Kaplan-Meier method was used to compare differences in terms of progression-free survival (PFS), cancer specific survival (CSS) and overall survival (OS) in an upfront ARTA or chemo-treated setting. Survival probabilities were computed at 12, 24, 48, and 60 months. Out of 216 patients, 88 cases with high-volume disease were selected. Sixty-nine patients (78.4%) received upfront ARTA, while 19 patients received chemotherapy as the first-line treatment option. Forty-eight patients received Abiraterone (AA), 21 patients received Enzalutamide (EZ) as the first-line treatment. The ARTA population was older (p = 0.007) and less likely to receive further lines of treatment (p = 0.001) than the chemo-treated cohort. The five-year PFS, CSS and OS were 60%, 73.3%, and 72.9%, respectively. Overall, 28 patients (31.8%) shifted after their first-line therapy to a second-line therapy: EZ was prescribed in 17 cases, AA in seven cases and radiometabolic therapy in four patients. Sixteen cases (18.2%) developed significant progression and were treated with chemotherapy. At Kaplan-Meyer analysis PFS, CSS and OS were comparable for upfront ARTA vs chemo-treated patients (log rank p = 0.10, p = 0.64 and p = 0.36, respectively). We reported comparable survival probabilities in a real-life series of high-volume mCRPC patients who either received upfront ARTA or chemotherapy. Patients primarily treated with chemotherapy were younger and more likely to receive further treatment lines than the upfront ARTA cohort. Our data support the use of novel antiandrogens as first line treatment regardless tumor burden, delaying the beginning of a more toxic chemotherapy in case of significant disease progression.
RESUMEN
The occurrence of gastric cancer has been associated with an increased risk of lobular breast tumors in a subset of patients harboring selected germline mutations. Among all, the germline alteration of the gene coding for E-Cadherin (CDH1) was associated with an increased risk of gastric cancer diffuse-histotype and lobular breast cancer. However, the risk assessment of breast neoplasms and the role of multiple prophylactic procedures in these patients has never been systematically addressed. In addition, the performance of the common screening procedures for lobular breast cancer like mammography is suboptimal. Therefore, recalling the need for a better articulation of the patient-centered strategies of surveillance for individuals with germline CDH1 and other similar alterations, to offer comprehensive approaches for prevention, early diagnosis, and treatment. Accordingly, this chapter aims to discuss the value and the role of integrated oncological care in the era of oncology sub-specializations. Additionally, it sheds light on how the harmonization across the health providers can enhance patient care in this setting.

People who use drugs (PWUDs) are generally considered "hard-to-treat" patients, due to adherence to HCV antiviral therapy or re-infection concerns. Linkage-to-care still remains a significant gap for HCV elimination, worsened by the COVID-19 pandemic. To reduce time-to-treat and improve treatment adherence, we have developed a patient-tailored model-of-care, decentralized within the addiction center and supervised remotely by hepatologists. From January 2017 to December 2020, patients were enrolled in one addiction care center in Southern Italy, where a complete hepatologic assessment, including blood chemistry, ultrasound, and transient elastography examination, was provided. DAAs treatment has been adapted on clinical features, also performing a daily administration during an outpatient visit, and monitored remotely by specialists via telemedicine interactions. Adherence was evaluated on the accomplishment of therapy or on the percentage of attended visits. From a total of 690 PWUDs, 135 had an active HCV infection and were enrolled in the study. All patients started the treatment within 3 weeks after HCV diagnosis. Six drop-outs were recorded, obtaining a sustained virological response at week 12 (SVR12) in 98.5% of PWUDs. There were only two cases of treatment failure, one of which is re-infection. No differences were found between the SVR12 rates before and during the COVID-19 pandemic. We obtained a high SVR12 rate, providing a comprehensive assessment within the addiction care center, tailoring the drug administration with a hepatologic remote stewardship. Our therapeutic model should improve the time-to-treat and treatment adherence in PWUDs.
RESUMEN
People who use drugs (PWUDs) are a crucial population in the global fight against viral hepatitis. The difficulties in linkage to care, the low adherence to therapy, the frequent loss to follow-up and the high risk of re-infection make the eradication process of the hepatitis C virus (HCV) really hard in this viral reservoir. Several management and treatment models have been tested with the aim of optimizing the HCV care cascade in PWUDs. Models of decentralization of the care process and integration of services seem to provide the highest success rates. Giving this, telemedicine could favor the decentralization of diagnostic-therapeutic management, key for the implementation of linkage to care, reduction of waiting times, optimization of adherence and results and reduction of the costs. The purpose of this literature review is to examine the role and possible impact of telemedicine in optimizing the HCV care cascade, comparing the different care models that have shown to improve the linkage to care and therapeutic adherence in this special population.
RESUMEN
Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease even in the early stages, despite progresses in surgical and pharmacological treatment in recent years. High potential for metastases is the main cause of therapeutic failure in localized disease, highlighting the current limited knowledge of underlying pathological processes. However, nowadays research is focusing on the search for personalized approaches also in the adjuvant setting for PDAC, by implementing the use of biomarkers and investigating new therapeutic targets. In this context, the aim of this narrative review is to summarize the current treatment scenario and new potential therapeutic approaches in early stage PDAC, from both a preclinical and clinical point of view. Additionally, the review examines the role of target therapies in localized PDAC and the influence of neoadjuvant treatments on survival outcomes.
RESUMEN
Cutaneous melanoma is a lethal disease, even when diagnosed in advanced stages. Although recent progress in biology and treatment has dramatically improved survival rates, new therapeutic approaches are still needed. Deregulation of epigenetics, which mainly controls DNA methylation status and chromatin remodeling, is implied not only in cancer initiation and progression, but also in resistance to antitumor drugs. Epigenetics in melanoma has been studied recently in both melanoma preclinical models and patient samples, highlighting its potential role in different phases of melanomagenesis, as well as in resistance to approved drugs such as immune checkpoint inhibitors and MAPK inhibitors. This review summarizes what is currently known about epigenetics in melanoma and dwells on the recognized and potential new targets for testing epigenetic drugs, alone or together with other agents, in advanced melanoma patients.

Hepatocellular carcinoma (HCC) is the primary tumour of the liver with the greatest incidence, particularly in the elderly. Additionally, improvements in the treatments for chronic liver diseases have increased the number of elderly patients who might be affected by HCC. Little evidence exists regarding HCC in old patients, and the elderly are still underrepresented and undertreated in clinical trials. In fact, this population represents a complex subgroup of patients who are hard to manage, especially due to the presence of multiple comorbidities. Therefore, the choice of treatment is mainly decided by the physician in the clinical practice, who often tend not to treat elderly patients in order to avoid the possibility of adverse events, which may alter their unstable equilibrium. In this context, the clarification of the optimal treatment strategy for elderly patients affected by HCC has become an urgent necessity. The aim of this review is to provide an overview of the available data regarding the treatment of HCC in elderly patients, starting from the definition of "elderly" and the geriatric assessment and scales. We explain the possible treatment choices according to the Barcelona Clinic Liver Cancer (BCLC) scale and their feasibility in the elderly population.
RESUMEN
Gastric cancer (GC) is the third cause of cancer-related death worldwide; the prognosis is poor especially in the case of metastatic disease. Liver, lymph nodes, peritoneum, and lung are the most frequent sites of metastases from GC; however, bone metastases from GC have been reported in the literature. Nevertheless, it is unclear how the metastatic sites may affect the prognosis. In particular, knowledge about the impact of bone metastases on GC patients' outcome is scant, and this may be related to the rarity of bone lesions and/or their underestimation at the time of diagnosis. In fact, there is still a lack of specific recommendation for their detection at the diagnosis. Then, the majority of the evidences in this field came from retrospective analysis on very heterogeneous study populations. In this context, the aim of this narrative review is to delineate an overview about the evidences existing about bone metastases in GC patients, focusing on their incidence and biology, the prognostic role of bone involvement, and their possible implication in the treatment choice.
RESUMEN
Pancreatic cancer represents one of the most lethal disease worldwide but still orphan of a molecularly driven therapeutic approach, although many genomic and transcriptomic classifications have been proposed over the years. Clinical heterogeneity is a hallmark of this disease, as different patients show different responses to the same therapeutic regimens. However, genomic analyses revealed quite a homogeneous disease picture, with very common mutations in four genes only (KRAS, TP53, CDKN2A, and SMAD4) and a long tail of other mutated genes, with doubtful pathogenic meaning. Even bulk transcriptomic classifications could not resolve this great heterogeneity, as many informations related to small cell populations within cancer tissue could be lost. At the same time, single cell analysis has emerged as a powerful tool to dissect intratumoral heterogeneity like never before, with possibility of generating a new disease taxonomy at unprecedented molecular resolution. In this review, we summarize the most relevant genomic, bulk and single-cell transcriptomic classifications of pancreatic cancer, and try to understand how novel technologies, like single cell analysis, could lead to novel therapeutic strategies for this highly lethal disease.

Background: The prognosis of patients with advanced gastric cancer remains overall poor despite some recent innovations and the development of new therapeutic approaches. Current European guidelines do not recommend any specific treatment for patients with advanced gastric cancer refractory to two or more previous chemotherapy regimens, making this setting "orphan." Immunotherapy is quickly evolving also for this malignancy even if with controversial results and the correct patient selection is still debated, especially for Western patients. The phase III ONO-4538-12 "ATTRACTION-2" represents the current landmark trial for the development of immunotherapy for pretreated Asian patients and led to the approval of Nivolumab in some Asian countries, while only previous phase trials are available for Caucasians. Complete radiological response is anecdotic and has never been described both in the pivotal trial both in the others with Western patients enrolled. Case presentation: We report two cases of heavily pretreated Western elderly patients with metastatic gastric cancer who experienced durable complete radiological response to Nivolumab "off label" (more than 20 months to date) in a clinical practice context. Molecular analysis of potential predictive factors has been performed (PD-L1, EBV, MSI, and TMB) on primary tumor sample. Conclusions: Despite the lack of evidence for Western patients and the controversial outcome with the use of checkpoint inhibitors in previous settings, immunotherapy may dramatically change the prognosis and the natural history of pretreated Western metastatic gastric cancer, in a correctly selected population. Microsatellite instability and tumor mutational burden may be reliable predictive factors also for Caucasians. There is an urgent need for a change in clinical practice also for this "orphan" patients and more efforts are needed in order to clarify the role of predictive factors for a correct patient selection and better chances of survival for this awful malignancy.
RESUMEN
PURPOSE: ATTRACTION-2 trial assessed the role of Nivolumab as a new standard treatment for Asian patients with pretreated metastatic gastric cancer (mGC). The aim of this analysis was to evaluate the safety and efficacy of Nivolumab in a real-life Western population, considering the lack of evidence to date. PATIENTS AND METHODS: Patients progressed after ≥2 chemotherapy regimens and able to receive Nivolumab (3 mg/kg q14) were eligible for the analysis. RESULTS: 16 patients received Nivolumab as third (81.3%) or fourth line (18.7%) from September 2017 to July 2019. The safety was in line with the literature and only one patient discontinued treatment due to persistent hematological toxicity. Overall response rate and disease control rate were 18.7% and 31.2%, respectively. Median duration of response was 5 months. With a median follow-up of 21 months, median OS was 6 months (7, 21 and 22 months in the responders) and median PFS 3 months. PD-L1 and microsatellite status were retrospectively collected in 12 patients. All the major responders were MSI, although no statistically significant difference in OS or PFS was observed according to molecular analysis. CONCLUSION: Nivolumab is feasible and effective in Western patients with mGC. Further investigation is urgently needed also in non-Asians.
RESUMEN
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.
RESUMEN
Nab-paclitaxel plus gemcitabine (Nab-Gem) represents one of the standard regimen for first-line treatment of metastatic pancreatic adenocarcinoma (mPDAC). However, few data are available in mPDAC relapsed after gemcitabine as adjuvant treatment. Our study aims to evaluate the efficacy and feasibility of Nab-Gem as first-line treatment for mPDAC patients previously treated with adjuvant treatment. We retrospectively analyzed the safety and efficacy data of 36 patients, who received first-line Nab-Gem after gemcitabine as adjuvant treatment. All patients received gemcitabine after radical surgery. Median disease-free survival was 12 months (95% CI 9.7-14.3); at relapse, all patients received Nab-Gem. We observed an objective response rate and disease control rate of 11.1% and 63.9%, respectively. With a median follow-up of 47 months, median progression-free survival was 5 months (95% CI 1.0-9.0), whereas median overall survival (OS) was 13 months (95% CI 5.5-20.5). Median OS was higher in patients with a relapse ≥ 7 months after the end of adjuvant treatment than in patients relapsed < 7 months (14 vs. 8 months, respectively, p: 0.52). Our results show that first-line Nab-Gem is feasible and effective in patients previously treated with gemcitabine as adjuvant treatment.

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.
RESUMEN
Gastric cancer (GC) is the fifth-most common cancer worldwide and an important cause of cancer-related-death. The growing knowledge of its molecular pathogenesis has shown that GC is not a single entity, but a constellation of different diseases, each with its own molecular and clinical characteristics. Currently, surgery represents the only curative approach for localized GC, but only 20% of patients (pts) showed resectable disease at diagnosis and, even in case of curative resection, the prognosis remains poor due to the high rate of disease relapse. In this context, multimodal perioperative approaches were developed in western and eastern countries in order to decrease relapse rates and improve survival. However, there is little consensus about the optimal treatment for non-metastatic GC. In this review, we summarize the current status and future developments of perioperative chemotherapy in resectable GC, attempting to find clear answers to the real problems in clinical practice.
RESUMEN
Despite some remarkable innovations and the advent of novel molecular classifications the prognosis of patients with advanced gastric cancer (GC) remains overall poor and current clinical application of new advances is disappointing. During the last years only Trastuzumab and Ramucirumab have been approved and currently used as standard of care targeted therapies, but the systemic management of advanced disease did not radically change in contrast with the high number of molecular drivers identified. The Cancer Genome Atlas (TCGA) and Asian Cancer Research Group (ACRG) classifications paved the way, also for GC, to that more contemporary therapeutic approach called "precision medicine" even if tumor heterogeneity and a complex genetic landscape still represent a strong barrier. The identification of specific cancer subgroups is also making possible a better selection of patients that are most likely to respond to immunotherapy. This review aims to critically overview the available molecular classifications summarizing the main druggable molecular drivers and their possible therapeutic implications also taking advantage of new technologies and acquisitions.

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.

The best choice of chemotherapy regimen for patients with metastatic gastric cancer is still debated. Although several studies support a superior efficacy of a triplet chemotherapy regimen over a doublet-based regimen, the magnitude of this benefit appears small and accompanied by an increased toxicity. Based on this background, we evaluated the outcome of patients with HER2-negative metastatic gastric cancer (mGC) who received in the clinical practice a triplet or doublet regimen as first-line therapy. A total of 165 patients (pts) with HER2-negative mGC treated outside of clinical trials at our department with FOLFOX-4 or ECX from 2012 and 2015 were included in our retrospective analysis: FOLFOX-4: 86 pts; ECX: 79 pts. Median progression-free survival (PFS) was 5.1 months for FOLFOX-4 and 5.6 months for ECX regimen, respectively. Median overall survival (OS) was 10.3 months for FOLFOX-4 and 10.9 months for ECX regimens. TOXICITY: grade 3-4 vomiting (12.6%), neutropenia (31.6%), mucositis (11.3%) and fatigue (22.7%) occurred more frequently in ECX regimen, while grade 3-4 peripheral neuropathy was more common with FOLFOX-4 (19.7%). Both evaluated regimens are active and safe in the palliation of HER2-negative mGC in the first-line setting: Three-drug chemotherapy regimen appear more active but offer only a slight improvement in OS with an increased G3-G4 toxicity. Our data suggest that a doublet therapy should be preferred in the clinical practice, preferentially reserving a three-drug combination to pts with bulky disease and/or to pts with initially unresectable locally advanced disease.
