Several recent trials have shown a significant overall survival (OS) benefit from postoperative cisplatin-based chemotherapy in patients with non-small-cell lung cancer (NSCLC). The aim of the Lung Adjuvant Cisplatin Evaluation was to identify treatment options associated with a higher benefit or groups of patients who particularly benefit from postoperative chemotherapy. ⋯ Postoperative cisplatin-based chemotherapy significantly improves survival in patients with NSCLC.

We conducted a phase II trial of preoperative gemcitabine and cisplatin chemotherapy in addition to chemoradiation (Gem-Cis-XRT) and pancreaticoduodenectomy (PD) for patients with stage I/II pancreatic adenocarcinoma. ⋯ Preoperative Gem-Cis-XRT did not improve survival beyond that achieved with preoperative gemcitabine-based chemoradiation (Gem-XRT) alone. The longer preoperative interval required more durable biliary decompression (metal stents) but was not associated with local tumor progression. The gemcitabine-based chemoradiation platform is a reasonable foundation on which to build future phase II multimodality trials for stage I/II pancreatic cancer incorporating emerging systemic therapies.

This phase II trial assessed the activity and tolerability of an oral dose of imatinib mesylate 400 mg twice daily in patients with recurrent or persistent epithelial ovarian or primary peritoneal carcinoma. The association between the expression of certain markers and clinical outcome was investigated. ⋯ Imatinib mesylate was well tolerated but had minimal single-agent activity in patients with recurrent ovarian or primary peritoneal carcinoma. No marker was identified that would predict activity of imatinib; however, tumor p-AKT and plasma VEGF levels were associated with poor outcome.

One of the concerns about intensity-modulated radiation therapy (IMRT) is that its tight dose distribution, an advantage in reducing RT morbidity to surrounding normal structures, might compromise tumor coverage. The purpose of this study is to determine if such concern is warranted in soft-tissue sarcoma (STS) of the extremity. ⋯ IMRT in STS of the extremity provides excellent local control in a group of patients with high risk features. This suggests that the precision with which IMRT dose is distributed has a beneficiary effect in sparing normal tissue and improving local control.

To investigate the sensitivity and accuracy of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for restaging the mediastinum after induction chemotherapy in patients with non-small-cell lung cancer (NSCLC). ⋯ EBUS-TBNA is a sensitive, specific, accurate, and minimally invasive test for mediastinal restaging of patients with NSCLC. However, because of the low negative predictive value, tumor-negative findings should be confirmed by surgical staging before thoracotomy.
