Lung cancer remains the first cause of cancer-related deaths worldwide. Thanks to the improvement in the knowledge of the biology of non-small cell lung cancer (NSCLC), patients’ survival has significantly improved. A growing number of targetable molecular alterations have been identified. Next-generation sequencing (NGS) has become one of the methodologies entered in clinical practice and was recently recommended by the European society for medical oncology (ESMO) to perform a comprehensive molecular characterization in patients with cancer. The current review provides an overview of the clinical trials that have explored the impact of NGS in patients with cancer, its limits, and advantages.

Although biliary tract cancers are traditionally considered rare in Western countries, their incidence and mortality rates are rising worldwide. A better knowledge of the genomic landscape of these tumor types has broadened the number of molecular targeted therapies, including angiogenesis inhibitors. The role of immune checkpoint inhibitors (ICIs) could potentially change the first-line therapeutic approach, but monotherapy with ICIs has shown disappointing results in CCA. Several clinical trials are evaluating combination strategies that include immunotherapy together with other anticancer agents with a synergistic activity. The tumor microenvironment (TME) composition plays a pivotal role in the prognosis of BTC patients. The accumulation of immunosuppressive cell types, such as tumor-associated macrophages (TAMs) and regulatory T-cells, together with the poor infiltration of cytotoxic CD8+ T-cells, is known to predispose to a poor prognosis owing to the establishment of resistance mechanisms. Likewise, angiogenesis is recognized as a major player in modulating the TME in an immunosuppressive manner. This is the mechanistic rationale for combination treatment schemes blocking both immunity and angiogenesis. In this scenario, this review aims to provide an overview of the most recent completed or ongoing clinical trials combining immunotherapy and angiogenesis inhibitors with/without a chemotherapy backbone.

Several trials have tried for decades to improve the outcome of extensive disease small cell lung cancer (ED-SCLC) through attempts to modify the standard treatments. Nevertheless, platinum/etoposide combination and topotecan have remained respectively the first and the second line standard treatments for the last 40 years. With the advent of immunotherapy, this scenario has finally changed. Our review aims to provide an overview of the primary studies on the actual therapeutic strategies available for ED-SCLC patients, and to highlight emerging evidence supporting the use of immunotherapy in SCLC patients.

Background: Although early-stage gastric cancer is a candidate for curative surgical resection, the absence of specific early symptoms results in a late diagnosis and consequently most patients present advanced or metastatic disease. Identifying noveland tumor-specific biomarkers is needed to increase early detection and match patients to the appropriate treatment. The present study focused on the possible prognostic role of Ectonucleotide Pyrophosphatase/Phosphodiesterase 2 (ENPP2)/Autotaxin (ATX) and lysophosphatidic acid (LPA) in GastroEsophageal Adenocarcinoma (GEA). High levels of ATX/LPA are associated with several malignancies including gastrointestinal tumors. Methods: Using a bioinformatics analysis, the incidence of ENPP2 mutations together with its expression in the tumor tissues and the correlation between the presence of mutations and the survival rate were examined in databases of GEA patients. Furthermore, circulating levels of ATX and LPA were studied retrospectively and longitudinally both in patients receiving frontal surgery and in patients receiving preoperative chemotherapy. Results: Overall findings suggested that although ENPP2 mutations occur at low incidence, their presence was associated with a particular poor Overall Survival (OS). Furthermore, removal of the tumour by surgery resulted in a decrease in serum ATX and LPA levels within five days, regardless of any previous chemotherapy. Basal circulating ATX were associated with the aggressive diffuse GEA and could be considered of negative prognostic value, mainly in combination models with circulating Carcino-Embryonic Antigen (CEA). Conclusions: Based on these observations, clinical trials with ATX-targeted drugs and standard chemotherapy regimens may benefit from selecting GEA patients based on their levels of ATX, LPA and CEA.
