Multimodality Treatment in Metastatic Gastric Cancer: From Past to Next Future.

ABSTRACT: Gastric cancer (GC) still remains an incurable disease in almost two-thirds of the cases. However, a deeper knowledge of its biology in the last few years has revealed potential biomarkers suitable for tailored treatment with targeted agents. This aspect, together with the improvement in early supportive care and a wiser use of the available cytotoxic drugs across multiple lines of treatment, has resulted in incremental and progressive survival benefits. Furthermore, slowly but surely, targeted therapies and immune checkpoint inhibitors are revising the therapeutic scenario even in metastatic GC and especially in particular subgroups. Moreover, important study results regarding the possible role of an integrated approach combining systemic, surgical, and locoregional treatment in carefully selected oligometastatic GC patients are awaited. This review summarizes the state-of-the-art and the major ongoing trials involving a multimodal treatment of metastatic GC.

Project description:The importance and role of the estrogen receptor (ER) pathway have been well-recognized in both breast cancer development and progression. The treatment of choice in women with estrogen receptor-positive metastatic breast cancer (ER+ mBC) is classically divided into a variety of endocrine therapies, with three of the most common being: selective estrogen receptor modulators (SERM), aromatase inhibitors (AI), and selective estrogen receptor degraders (SERD). However, resistance develops in 30-50% of patients treated with these endocrine therapies due to a sophisticated and at times redundant interference at the molecular level between the ER, growth factors, and downstream cell-signaling pathways. Tumor response is heightened with adjunctive therapy that includes an mTORC1 inhibitor (everolimus), CDK4/6 inhibitors (palbociclib/ribociclib/abemaciclib), and an α isoform-specific PI3K inhibitor (alpelisib). Each of these inhibitors elicits potent anti-proliferative benefits; however, they fail to induce tumor cell death. Consequently, disease progression almost invariably occurs. Evasion of apoptosis is a hallmark of cancer. The p53 and BCL2 represent two important nodes of the apoptosis signaling pathway. Venetoclax, a potent and selective BCL2 inhibitor, synergizes with hormonal therapy in ER+ breast cancer models and is active in clinical trials. Similarly, an MDM2 inhibitor, AMG-232, which induces p53 is active in early clinical trials of both liquid and advanced solid tumor patients. In our ER+ BC cohort (Avera Cancer Institute, Sioux Falls, SD), we observed more than 70% of wild type TP53 and over 10% amplification of MDM2 and MDM4 as comparable with the TCGA data set. We summarized current treatment options, the molecular mechanisms that predispose to endocrine resistance, and a future pro-apoptotic treatment strategy for ER+ mBC patients. Our review presents critical analyses of the therapeutic options for the clinical management of ER+ Metastatic Breast Cancer in the light of a hypothesis targeting the induction of apoptosis in p53 wild type tumors. We reviewed not only the FDA approved current treatment approaches but also presented a discourse addressing the possibilities for novel combination strategy that can induce tumor cell apoptosis, a critical cellular mechanism delaying/denying tumor progression. Our review is unique as it presents patient data in support of our hypothesis.
