New Era

Metastatic gastric cancer is associated with a poor prognosis and novel treatment options are desperately needed. The development of targeted therapies heralded a new era for the management of metastatic gastric cancer, however results from clinical trials of numerous targeted agents have been mixed. The advent of immune checkpoint inhibitors has yielded similar promise and results from early trials are encouraging. This review provides an overview of the systemic treatment options evaluated in metastatic gastric cancer, with a focus on recent evidence from clinical trials for targeted therapies and immune checkpoint inhibitors. The failure to identify appropriate predictive biomarkers has hampered the success of many targeted therapies in gastric cancer, and a deeper understanding of specific molecular subtypes and genomic alterations may allow for more precision in the application of novel therapies. Identifying appropriate biomarkers for patient selection is essential for future clinical trials, for the most effective use of novel agents and in combination approaches to account for growing complexity of treatment options.

Targeted therapies are efficient in the context of oncogenic driver mutations. Epidermal growth factor receptor (EGFR)-mutant lung cancers represent a distinct subset of non-small-cell lung cancer (NSCLC) with marked sensitivity to EGFR tyrosine kinase inhibitors (TKIs). Despite the high response rate to EGFR TKIs in EGFR-mutant lung cancer, resistance and tumor recurrence are unavoidable. Therapeutic options are restricted in patients after exhaustion of targeted therapies. Immune checkpoint inhibitors (ICIs) represent a novel therapeutic option for advanced NSCLC with significant overall survival benefit in registration trials. No superiority in terms of long-term survival was observed in the EGFR mutation subgroup when ICIs were given as monotherapy in second-line treatment in earlier studies. Thus, the appropriate application of ICIs to patients harboring EGFR mutations remains an important field of ongoing research. Here, we discuss different immune checkpoint blockade strategies, including ICIs alone and in combination with TKIs, chemotherapy, radiation, and antiangiogenic agents in EGFR-mutant NSCLC as first-line and subsequent treatments. We also summarize the evidence concerning the heterogeneous molecular features and immune signatures of EGFR mutations and their associations with ICI therapy outcomes. This study was performed to improve our understanding of the optimal mode of immune-based treatment approaches in EGFR-mutant NSCLC.

The landscape of treatments for non–small cell lung cancer (NSCLC) has evolved dramatically over the past 3 decades. A better understanding of the disease biology and identification of actionable genetic alterations heralded an era of targeted therapies that has led to unprecedented survival benefits in patients with oncogene-driven NSCLC. More recent breakthroughs in immunotherapy led to the development of immune checkpoint inhibitors that have changed the treatment paradigm for patients with advanced NSCLC because of their ability to produce durable responses, resulting in improved survival outcomes. Despite the unparalleled success of these agents, primary and acquired resistance to these therapies pose a formidable challenge. In this article, we provide an overview of the therapeutic advances in the treatment of NSCLC, mechanisms of resistance, and potential strategies to overcome resistance to targeted therapies and immune checkpoint inhibitors.

Abstract The clinical outcome of BRAF-mutated advanced melanoma has been improved by both molecular targeted therapies and immune checkpoint inhibitors. Long-term follow-up data reveal durable clinical responses in patients receiving first-line combinations of BRAF inhibitors plus MEK inhibitors, particularly those showing a complete response. Clinical outcomes are also associated with the lactate dehydrogenase levels and the number of metastatic organs. Although brain metastasis is frequently difficult to control, systemic therapy is preferred in cases with small and asymptomatic brain metastases associated with progressive extra-cranial disease. Control of intra-cranial disease with BRAF inhibitors plus MEK inhibitors is comparable with that of immune checkpoint inhibitors, although immune checkpoint inhibitors are superior to targeted therapies with respect to survival. The BRAF inhibitors plus MEK inhibitors regimen is well-tolerated, and toxicities are usually manageable and reversible, but differ according to the specific regimen used. Guidelines in the United States, Europe, and Japan recommend targeted therapy for patients who need early tumor responses. A meta-analysis of retrospective data shows that the baseline lactate dehydrogenase level is significantly higher in patients treated with BRAF inhibitors plus MEK inhibitors than in those treated with immune checkpoint inhibitors, suggesting that clinicians tend to use BRAF inhibitors plus MEK inhibitors for more advanced disease. Since there is insufficient efficacy and safety data on the use of targeted therapies for acral and mucosal melanoma, a retrospective analysis may be useful. The combination of molecular targeted therapy plus immune checkpoint inhibitors is expected to elicit further improvement. The results of several trials using combination or sequential therapies will be available in the next few years.

Melanoma Patients

Melanoma is the least common but deadliest type of skin cancer. Melanomagenesis is driven by a series of mutations and epigenetic alterations in oncogenes and tumor suppressor genes that allow melanomas to grow, evolve, and metastasize. Epigenetic alterations can also lead to immune evasion and development of resistance to therapies. Although the standard of care for melanoma patients includes surgery, targeted therapies, and immune checkpoint blockade, other therapeutic approaches like radiation therapy, chemotherapy, and immune cell-based therapies are used for patients with advanced disease or unresponsive to the conventional first-line therapies. Targeted therapies such as the use of BRAF and MEK inhibitors and immune checkpoint inhibitors such as anti-PD-1 and anti-CTLA4 only improve the survival of a small subset of patients. Thus, there is an urgent need to identify alternative standalone or combinatorial therapies. Epigenetic modifiers have gained attention as therapeutic targets as they modulate multiple cellular and immune-related processes. Due to melanoma’s susceptibility to extrinsic factors and reversible nature, epigenetic drugs are investigated as a therapeutic avenue and as adjuvants for targeted therapies and immune checkpoint inhibitors, as they can sensitize and/or reverse resistance to these therapies, thus enhancing their therapeutic efficacy. This review gives an overview of the role of epigenetic changes in melanoma progression and resistance. In addition, we evaluate the latest advances in preclinical and clinical research studying combinatorial therapies and discuss the use of epigenetic drugs such as HDAC and DNMT inhibitors as potential adjuvants for melanoma patients.
