Pemetrexed plus cisplatin versus docetaxel plus cisplatin for stage IV lung adenocarcinoma based on propensity score matching.

The aim of this study was to compare the clinical efficacy of pemetrexed+cisplatin (PP) versus docetaxel+cisplatin (DP) for the treatment of stage IV lung adenocarcinoma. We retrospectively analyzed the clinical data of 147 patients with stage IV lung adenocarcinoma treated between January 2011 and December 2015, 100 of which were in the DP group whereas 47 were in the DP group. Main inclusion criteria were treatment-naive patients, first-line treatment with PP or DP with no molecular targeted therapy during treatment, 2-6 cycles of first-line chemotherapy with unknown status of epidermal growth factor receptor (EGFR) mutation, 18-75 years of age, and Karnofsky performance status score of at least 70.

Pathogenesis and Prevention of Radiation-induced Myocardial Fibrosis.

Radiation therapy is one of the most important methods for the treatment of malignant tumors. However, in radiotherapy for thoracic tumors such as breast cancer, lung cancer, esophageal cancer, and mediastinal lymphoma, the heart, located in the mediastinum, is inevitably affected by the irradiation, leading to pericardial disease, myocardial fibrosis, coronary artery disease, valvular lesions, and cardiac conduction system injury, which are considered radiation-induced heart diseases. Delayed cardiac injury especially myocardial fibrosis is more prominent, and its incidence is as high as 20–80%.

Primary mediastinal sarcoma: surgical outcomes of 21 cases.

Objectives: Primary sarcomas of the mediastinum are relatively rare. This article reviews the surgical outcomes of 21 cases diagnosed with localized mediastinal sarcomas receiving multidisciplinary treatment modalities in Sichuan province, China, from January 1996 to January 2011.

Methods: Twenty-one cases of histologically diagnosed primary mediastinal sarcoma undergoing surgical treatment were reviewed retrospectively.
