Phase I Study of Docetaxel Plus Nedaplatin in Patients With Metastatic or Recurrent Esophageal Squamous Cell Carcinoma After Cisplatin Plus 5-Fluorouracil Treatment.
To date, no second-line chemotherapy regimen for esophageal squamous cell carcinoma (SCC) has been established. This clinical trial aimed to assess the optimum dose of docetaxel plus nedaplatin (cis-diammine-glycolate platinum) as second-line chemotherapy. ⋯ Docetaxel plus nedaplatin chemotherapy seems to be a safe and feasible second-line regimen for the treatment of esophageal SCC. We recommend the administration of 50 mg/m² docetaxel (day 1) plus 70 mg/m² nedaplatin (day 1) every 4 weeks in a phase II study.

Academic and Resident Radiation Oncologists' Attitudes and Intentions Regarding Radiation Therapy near the End of Life.
There has been increasing scrutiny about cancer treatment for patients very near the end of life (EoL), yet a substantial number receive palliative radiation therapy (RT) in this setting. Our aim was to document the attitudes and intentions of thought leaders and trainees in giving RT near the EoL. ⋯ Survey respondents, 89% of whom were academic radiation oncologists, have a positive view of palliative RT near the EoL. They favor shorter fractionation for patients near the EoL. Personal experience is most important in shaping practices and attitudes.

ReviewCTLA-4 and PD-1 Pathways: Similarities, Differences, and Implications of Their Inhibition.
The cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and programmed death 1 (PD-1) immune checkpoints are negative regulators of T-cell immune function. Inhibition of these targets, resulting in increased activation of the immune system, has led to new immunotherapies for melanoma, non-small cell lung cancer, and other cancers. Ipilimumab, an inhibitor of CTLA-4, is approved for the treatment of advanced or unresectable melanoma. ⋯ CTLA-4 is thought to regulate T-cell proliferation early in an immune response, primarily in lymph nodes, whereas PD-1 suppresses T cells later in an immune response, primarily in peripheral tissues. The clinical profiles of immuno-oncology agents inhibiting these 2 checkpoints may vary based on their mechanistic differences. This article provides an overview of the CTLA-4 and PD-1 pathways and implications of their inhibition in cancer therapy.

Induction Chemotherapy Followed by Concurrent Full-dose Gemcitabine and Intensity-modulated Radiation Therapy for Borderline Resectable and Locally Advanced Pancreatic Adenocarcinoma.
To evaluate the outcomes and toxicity of concurrent full-dose gemcitabine and intensity-modulated radiation therapy (IMRT) for patients with borderline resectable and locally advanced pancreatic adenocarcinoma after induction chemotherapy. ⋯ Concurrent full-dose gemcitabine and limited-field IMRT after induction chemotherapy for the treatment of borderline resectable and locally advanced pancreatic cancer is promising with acceptable toxicity rates.
