Review Meta Analysis
Optimal adjuvant therapy for resected hepatocellular carcinoma: a systematic review with network meta-analysis.
Major adjuvant therapies (ATs) for resected hepatocellular carcinoma (HCC) include chemotherapy, internal radiation therapy (IRT), interferon therapy (IFNT) and immunotherapy but the optimum regimen remains inconclusive. We aim to compare these therapies in terms of patient survival and recurrence rates. ⋯ IFNT was the most efficacious AT regimen both for short and long term survivals. Immunotherapy and IFNT were the most two effective in preventing overall relapse for resected HCC.

Review Meta Analysis
Are VEGFR-TKIs effective or safe for patients with advanced non-small cell lung cancer?
Vascular endothelial growth factor receptor tyrosine kinase inhibitors (VEGFR-TKIs) might be new therapeutic strategies for advanced non-small cell lung cancer (NSCLC). Here a total of 12,520 patients from 23 randomized controlled trials (RCTs) were enrolled to evaluate the efficacy and safety of VEGFR-TKIs quantitatively in advanced NSCLC. Compared with non-VEGFR-TKIs, VEGFR-TKIs regimen significantly improved progression-free survival (PFS) [hazard ratio (HR): 0.839, 95% confidence interval (CI): 0.805-0.874, P < 0.001], objective response rates (ORR) [relative risk (RR): 1.374, 95%CI: 1.193-1.583, P < 0.001] and disease control rates (DCR) (RR: 1.113, 95%CI: 1.027-1.206, P =0.009), but not overall survival (OS) (HR: 0.960, 95%CI: 0.921-1.002, P =0.060) for NSCLC patients. ⋯ As for high-grade (≥3) adverse events (AEs), VEGFR-TKIs were associated with higher RR of neutropenia, thrombocytopenia, hypertension, fatigue, stomatitis, diarrhea, rash and HFSR. This study demonstrates VEGFR-TKIs improve PFS, ORR and DCR, but not OS in advanced NSCLC patients. VEGFR-TKIs induce more frequent and serious AEs compared with control therapies.

Randomized Controlled Trial Comparative Study
Erlotinib is effective in pancreatic cancer with epidermal growth factor receptor mutations: a randomized, open-label, prospective trial.
To analyze the efficacy of gemcitabine with or without erlotinib for pancreatic cancer, and to determine the predictive role of epidermal growth factor receptor (EGFR) and KRAS mutations in these patients. ⋯ Gemcitabine plus erlotinib is more effective than gemcitabine alone for treating metastatic pancreatic cancer patients, especially those with EGFR mutations. ClinicalTrials.gov number, NCT01608841.

Gastric carcinoma is one of the most common malignancies and the third highest cause of global cancer-related death. Notch2 receptor intracellular domain (N2IC), the activated form of Notch2 receptor, enhances gastric carcinogenesis. MicroRNAs (miRNAs) act as either oncogenes or tumor suppressors in tumorigenesis and cross-talk with Notch pathways. ⋯ Mechanistically, miR-23b suppressed tumor progression and pluripotency gene expression and affected tumorsphere ultra-structure in gastric cancer cells via targeting Notch2 receptor or Ets1. Furthermore, miR-23b diminished the xenografted tumor growth and lung metastasis of SC-M1 gastric cancer cells through Notch2 pathway. Our results suggest that Notch2 pathway and miR-23b interplay in a reciprocal regulation loop in gastric cancer cells and this axis plays an important role in gastric carcinogenesis.

Cancer testis antigens (CTAs) are widely expressed in tumor tissues, circulating tumor cells (CTCs) and in cancer derived exosomes that are frequently engulfed by lymphoid cells. To determine whether tumor derived CTA mRNAs could be detected in RNA from purified peripheral blood mononuclear cells (PBMC) of non-small cell lung cancer (NSCLC) patients, we assayed for the expression of 116 CTAs in PBMC RNA in a discovery set and identified AKAP4 as a potential NSCLC biomarker. We validated AKAP4 as a highly accurate biomarker in a cohort of 264 NSCLCs and 135 controls from 2 different sites including a subset of controls with high risk lung nodules. ⋯ AKAP4 expression increases significantly with tumor stage, but independent of age, gender, smoking history or cancer subtype. Follow-up studies in a small number of resected NSCLC patients revealed a decrease of AKAP4 expression post-surgical resection that remained low in patients in remission and increased with tumor recurrence. AKAP4 is a highly accurate biomarker for the detection of early stage lung cancer.
