Advances in oncology research have led to identification of tumor-specific biomarkers, some of which are important predictive indicators and ideal targets for novel therapeutics. One such biomarker in non-small cell lung cancer (NSCLC) is the epidermal growth factor receptor (EGFR). Patients with NSCLC who harbor an activating EGFR mutation show a more favorable response to treatment with an EGFR inhibitor, such as gefitinib, erlotinib, or afatinib, than to chemotherapy. The prevalence of EGFR mutations in East Asian patients is higher than that in other populations, and in some clinical settings, patients have been treated with EGFR inhibitors based on clinicopathologic characteristics with no information on EGFR status. However, based on results from a series of studies in which East Asian patients with advanced non-squamous NSCLC were treated with EGFR inhibitors alone or in combination with standard chemotherapy, this may not be the best practice because EGFR mutation status was found to be a key predictor of outcome. Data from these studies highlight the necessity of EGFR testing in determining the most suitable treatment for patients with advanced or metastatic NSCLC.

PURPOSE: A recent phase III study (PARAMOUNT) demonstrated that pemetrexed continuation maintenance therapy is a new treatment paradigm for advanced nonsquamous non-small cell lung cancer (NSCLC). The majority of patients enrolled in PARAMOUNT were Caucasian (94%). We reviewed efficacy and safety data from two clinical trials, which enrolled East Asian (EA) patients, to supplement data from PARAMOUNT on pemetrexed continuation maintenance therapy in patients with nonsquamous NSCLC. MATERIALS AND METHODS: Study S110 was a phase II, multicenter, randomized, controlled, open-label trial in never-smoker, chemonaive, EA patients (n=31) with locally advanced or metastatic nonsquamous NSCLC (n=27). Study JMII was a multicenter, open-label, single-arm, post-marketing, clinical trial in Japanese patients (n=109) with advanced nonsquamous NSCLC. PARAMOUNT was a multicenter, randomized, double-blind, placebo-controlled trial in patients with advanced nonsquamous NSCLC. RESULTS: In EA patients with nonsquamous NSCLC, the median progression-free survival (PFS) for pemetrexed continuation maintenance therapy was 4.04 months (95% confidence interval [CI], 3.22 to 5.29 months) in study S110 and 3.9 months (95% CI, 3.2 to 5.2 months) in study JMII. The median PFS for pemetrexed continuation maintenance therapy in PARAMOUNT was 4.1 months (95% CI, 3.2 to 4.6 months). Pemetrexed continuation maintenance therapy in EA patients in studies S110 and JMII did not lead to any unexpected safety events, and was consistent with PARAMOUNT's safety profile. CONCLUSION: The efficacy and safety data in the EA trials were similar to those in PARAMOUNT despite differences in patient populations and study designs. These data represent consistent evidence for pemetrexed continuation maintenance therapy in EA patients with advanced nonsquamous NSCLC.

PURPOSE: The purpose of this study was to understand patient treatment patterns, outcomes, and healthcare resource use in cases of metastatic and/or locally recurrent, unresectable gastric cancer (MGC) in South Korea. MATERIALS AND METHODS: Thirty physicians reviewed charts of eligible patients to collect de-identified data. Patients must have received platinum/fluoropyrimidine first-line therapy followed by second-line therapy or best supportive care, had no other primary cancer, and not participated in a clinical trial following MGC diagnosis. Data were summarized using descriptive statistics. Kaplan-Meier analysis was used to describe survival. RESULTS: Of 198 patients, 73.7% were male, 78.3% were diagnosed with MGC after age 55 (mean, 61.3 years), and 47.0% were current or former smokers. The majority of tumorswere located in the antrum/pylorus (51.5%). Metastatic sites most often occurred in the peritoneum (53.5%), lymph nodes (47.5%), and liver (38.9%). At diagnosis, the mean Charlson comorbidity indexwas 0.4 (standard deviation, 0.6). The most common comorbidities were chronic gastritis (22.7%) and cardiovascular disease (18.7%). Most patients (80.3%) received second-line treatment. Single-agent fluoropyrimidine was reported for 22.0% of patients, while 19.5% were treated with irinotecan and a fluoropyrimidine or platinum agent. The most common physician-reported symptoms during second-line treatment were nausea/vomiting (44.7%) and pain (11.3%), with antiemetics (44.7%), analgesics (36.5%), and nutritional support (11.3%) most often used as supportive care. Two-thirds of inpatient hospitalizations were for chemotherapy infusion. Outpatient hospitalization (31.6%) and visits to the oncologist (58.8%) were common among second-line patients. CONCLUSION: Most patients received second-line treatment, although regimens varied. Understanding MGC patient characteristics and treatment patterns in South Korea will help address unmet needs.

Despite advancements in therapy for advanced gastric and gastroesophageal junction cancers, their prognosis remains dismal. Tumor angiogenesis plays a key role in cancer growth and metastasis, and recent studies indicate that pharmacologic blockade of angiogenesis is a promising approach to therapy. In this systematic review, we summarize current literature on the clinical benefit of anti-angiogenic agents in advanced gastric cancer. We conducted a systematic search of PubMed and conference proceedings including the American Society of Clinical Oncology, the European Society for Medical Oncology, and the European Cancer Congress. Included studies aimed to prospectively evaluate the efficacy and safety of anti-angiogenic agents in advanced gastric or gastroesophageal junction cancer. Each trial investigated at least one of the following endpoints: overall survival, progression-free survival/time to progression, and/or objective response rate. Our search yielded 139 publications. Forty-two met the predefined inclusion criteria. Included studies reported outcomes with apatinib, axitinib, bevacizumab, orantinib, pazopanib, ramucirumab, regorafenib, sorafenib, sunitinib, telatinib, and vandetanib. Second-line therapy with ramucirumab and third-line therapy with apatinib are the only anti-angiogenic agents so far shown to significantly improve survival of patients with advanced gastric cancer. Overall, agents that specifically target the vascular endothelial growth factor ligand or receptor have better safety profile compared to multi-target tyrosine kinase inhibitors.

Background/Aims: Nonalcoholic fatty liver disease (NAFLD) is closely associated with diabetes. The cumulative impact of both diseases synergistically increases risk of adverse events. However, present population analysis is predominantly conducted with reference to non-NAFLD individuals and has not yet examined the impact of prediabetes. Hence, we sought to conduct a retrospective analysis on the impact of diabetic status in NAFLD patients, referencing non-diabetic NAFLD individuals. Methods: Data from the National Health and Nutrition Examination Survey 1999–2018 was used. Hepatic steatosis was defined with United States Fatty Liver Index (US-FLI) and FLI at a cut-off of 30 and 60 respectively, in absence of substantial alcohol use. A multivariate generalized linear model was used for risk ratios of binary outcomes while survival analysis was conducted with Cox regression and Fine Gray model for competing risk. Results: Of 32,234 patients, 28.92% were identified to have NAFLD. 36.04%, 38.32% and 25.63% were non-diabetic, prediabetic and diabetic respectively. Diabetic NAFLD significantly increased risk of cardiovascular disease (CVD), stroke, chronic kidney disease, all-cause and CVD mortality compared to non-diabetic NAFLD. However, prediabetic NAFLD only significantly increased the risk of CVD and did not result in a higher risk of mortality. Conclusions Given the increased risk of adverse outcomes, this study highlights the importance of regular diabetes screening in NAFLD and adoption of prompt lifestyle modifications to reduce disease progression. Facing high cardiovascular burden, prediabetic and diabetic NAFLD individuals can benefit from early cardiovascular referrals to reduce risk of CVD events and mortality.
