BACKGROUNDS Recent clinical trials have shown that immune-checkpoint blockade yields remarkable response in a subset of non-small cell lung cancer (NSCLC) patients. However, few studies directly focus on the association between epidermal growth factor receptor (EGFR) mutational status and programmed cell death-ligand 1 (PD-L1) expression. We examined(More)
The distant metastasis free survival (DMFS) and overall survival (OS) differ significantly among individuals even within the same clinical stages. The purpose of this retrospective study was to build nomograms incorporating plasma EBV DNA for predicting DMFS and OS of nasopharyngeal carcinoma (NPC) patients after definitive radiotherapy. A total of 1168(More)
BACKGROUND Outcomes are poor for patients with recurrent or metastatic nasopharyngeal carcinoma and no well established first-line chemotherapy is available for the disease. We compared the efficacy and safety of gemcitabine plus cisplatin versus fluorouracil plus cisplatin in patients with recurrent or metastatic nasopharyngeal carcinoma. METHODS In this(More)
OBJECTIVES Tumor-associated macrophages (TAMs) are thought to be involved in the perineural invasion (PNI) process and to be associated with poor prognoses. The associations between TAMs, PNI, and clinicopathological features in pancreatic ductal adenocarcinomas (PDAs) remain to be elucidated. METHODS Fifty-nine PDA patients who had undergone(More)
BACKGROUND Poor nutritional status is associated with progression and advanced disease in patients with cancer. The prognostic nutritional index (PNI) may represent a simple method of assessing host immunonutritional status. This study was designed to investigate the prognostic value of the PNI for distant metastasis-free survival (DMFS) in patients with(More)
