A narrative review of the evolving landscape of the management of metastatic gastric cancer: the role of targeted therapies.

ABSTRACT:

Background and objective

Gastric cancer is the fifth most common cancer worldwide and the fourth leading cause of cancer-related death. Unfortunately, patients often present with advanced disease at diagnosis, which is directly related to its high mortality. Numerous trials, as early as the 1980's, have shown that cytotoxic chemotherapy improves survival. This review will focus on targeted therapies and immunotherapies which have emerged as treatment options for metastatic gastric cancer, often used in conjunction with cytotoxic chemotherapy. Here we will review the relevant clinical trials of targeted therapies and immunotherapies in the treatment of metastatic gastric cancer.

Methods

We performed an extensive review of articles in the PubMed database pertaining to targeted therapies and immunotherapies in the treatment of metastatic gastric cancer. Additionally, updated guidelines from the National Comprehensive Cancer Network (NCCN) and European Society for Medical Oncology (ESMO) were reviewed.

Key content and findings

Cytotoxic chemotherapy remains the backbone of treatment of metastatic gastric cancer, but the development of targeted therapies and immunotherapy have revolutionized its treatment with improved survival and outcomes. Therapies have been developed which target human epidermal growth factor receptor 2 (HER2), vascular endothelial growth factor receptor-2 (VEGFR-2), and tyrosine kinase pathways. Novel targeted therapies are currently being investigated with promising results thus far. Immunotherapy, specifically immune checkpoint inhibitors (ICIs), has proven to be a significant advancement in the treatment of gastric cancer.

Conclusions

Targeted therapies and immunotherapies have improved survival and outcomes in metastatic gastric cancer, however more research is needed to make even greater strides.

Project description:BackgroundMetastatic urothelial carcinoma (mUC) historically is treated with first-line platinum-based combination chemotherapy, preferably cisplatin plus gemcitabine whenever possible. In recent years, multiple classes of targeted therapy have demonstrated benefit, with some receiving approval in mUC. This review will summarize phase III efficacy and safety data for targeted agents, principally immune checkpoint inhibitors (ICIs), as either first-line or first-line switch-maintenance therapy for mUC and interpret these findings in the context of the current treatment landscape.Materials and methodsPublished and presented phase III data on targeted therapy for the first-line or first-line switch-maintenance treatment of mUC were identified using the key search terms "targeted therapy" AND "urothelial carcinoma" AND "advanced" OR respective aliases according to the guidelines for Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).ResultsOf the six eligible phase III targeted therapy trials, two assessing ICIs met their primary endpoints in platinum-eligible patients. First-line ICI plus chemotherapy combinations have not improved overall survival (OS), although final OS results of the IMVigor 130 trial are pending. Switch-maintenance using an ICI in patients achieving at least stable disease following platinum-based chemotherapy statistically significantly improved OS (21.4 vs. 14.3 months, hazard ratio, 0.69; 95% confidence interval, 0.56-0.86; p = .001). Current sequencing options for mUC include first-line platinum-based chemotherapy with a switch to ICI either immediately or upon disease progression.ConclusionRecent targeted therapy trials have expanded ICI sequencing options for mUC. The treatment landscape is likely to evolve rapidly, with results from multiple phase III trials expected in the next 5 years.Implications for practiceMultiple classes of targeted agents are approved for use in metastatic urothelial carcinoma (mUC). Six phase III trials have recently provided insight on the benefit of these agents in the first-line setting. In platinum-eligible patients, immune checkpoint inhibitors (ICIs) combined with first-line platinum-based chemotherapy failed to demonstrate improved survival, although ICI monotherapy as switch-maintenance significantly improved overall survival in patients with mUC who had achieved at least stable disease following first-line platinum-based chemotherapy. In patients ineligible for any chemotherapy, pembrolizumab, atezolizumab, or pembrolizumab in combination with enfortumab vedotin may be options.
