Epigenetic inactivation of tumor suppressor genes is involved in the development of malignant pleural mesothelioma (MPM). ZIC1, a potential tumor suppressor gene involved in regulating cell growth and apoptosis, was investigated in MPM cell lines and tumors. ⋯ ZIC1 is down-regulated in MPM through promoter methylation and acts as a tumor suppressor through down-regulation of its direct targets miR-23a and miR-27a.

The purpose of this study was to evaluate whether consolidation chemotherapy (CCT) after concurrent chemo-radiotherapy is beneficial for patients with locally advanced non-small-cell lung cancer (LA-NSCLC). ⋯ The pooled analysis based on a publication basis failed to provide evidence that CCT yields significant survival benefit for LA-NSCLC.

Multicenter Study
KRAS mutations in advanced nonsquamous non-small-cell lung cancer patients treated with first-line platinum-based chemotherapy have no predictive value.
Kirsten rat sarcoma viral oncogene homolog (KRAS) mutation is thought to be related with dismal outcome for non-small-cell lung cancer (NSCLC) patients. The role of KRAS mutation as a predictor of response to chemotherapy for patients with metastatic NSCLC is poorly understood. ⋯ On the basis of our multicenter data presented here, we conclude that KRAS mutation is not predictive for worse response to chemotherapy, PFS, and OS in advanced NSCLC patients treated with platinum-based chemotherapy in first-line setting.

Bevacizumab improves survival in patients with advanced non-small-cell lung cancer (NSCLC). This phase II clinical trial assessed the effects of the addition of bevacizumab to neoadjuvant chemotherapy in resectable nonsquamous NSCLC. ⋯ Although preoperative bevacizumab plus chemotherapy was feasible, it did not improve downstaging in unselected patients. New cavitation after single-agent bevacizumab is a potential biomarker. Alternative strategies are needed for KRAS-mutant tumors.

Initial complete resection is a powerful prognostic indicator of survival in thymic epithelial tumors (TETs), but is obviously related to tumor stage. Here, we report the results of a prospective study of neoadjuvant docetaxel/cisplatin in locally advanced TETs. ⋯ Neoadjuvant docetaxel/cisplatin is both feasible and well tolerated, and potentially improves surgical resectability in patients with advanced TETs.
