Article Synopsis
  • * It identifies a specific population of Ki67 proliferating regulatory T cells that express immunosuppressive markers, which correlates with treatment outcomes; higher levels were seen in patients who relapsed.
  • * The findings indicate that low baseline levels of these Ki67 Tregs can predict the effectiveness of immunotherapy, and similar results were confirmed in two other trials, suggesting a potential for personalized treatment strategies.

Background: Anti-PD-1 therapy and chemotherapy is a recommended first-line treatment for recurrent or metastatic nasopharyngeal carcinoma, but the role of PD-1 blockade remains unknown in patients with locoregionally advanced nasopharyngeal carcinoma. We assessed the addition of sintilimab, a PD-1 inhibitor, to standard chemoradiotherapy in this patient population.

Methods: This multicentre, open-label, parallel-group, randomised, controlled, phase 3 trial was conducted at nine hospitals in China.

The pan-immune-inflammation-value (PIV) is a comprehensive biomarker that integrates different peripheral blood cell subsets. The present study aimed to evaluate the prognostic ability of PIV in patients with nasopharyngeal carcinoma (NPC) undergoing chemoradiotherapy. PIV was assessed using the following equation: (Neutrophil count × platelet count × monocyte count)/lymphocyte count.

Radiation-related nasopharyngeal necrosis (RRNN) is a rare and often fatal complication in patients with nasopharyngeal carcinoma (NPC). Currently, no standard treatments are recommended for RRNN. The effects of traditional conservative treatments are suboptimal, and surgery for RRNN cannot be performed by inexperienced doctors.

Background: Paclitaxel-based chemotherapy represented by nanoparticle albumin-bound paclitaxel (nab-ptx) combined with programmed cell death protein 1 (PD-1)/programmed death ligand 1 (PD-L1) inhibitors has become the standard model for the 1 treatment of advanced non-small cell lung cancer (NSCLC) with negative driver genes (such as , etc.), indicating that nab-ptx and PD-1/PD-L1 inhibitors are synergistic. Considering PD-1/PD-L1 inhibitors alone or chemotherapy single has limited efficiency in the 2 line or above of NSCLC, so it is of great significance to explore the combination of PD-1/PD-L1 inhibitors and nab-ptx to further improve the therapeutic efficiency in such field.

Neuroendocrine carcinoma (NEC) of the nasopharynx is rare and its clinical and pathologic characteristics have remained to be fully elucidated. The present study reported on a case of Epstein-Barr virus (EBV)-positive NEC of the nasopharynx that exhibited features of large-cell NEC and small-cell NEC, as confirmed by immunohistochemical staining. The patient received three cycles of induction chemotherapy (with docetaxel-cisplatin) that was followed by concurrent chemoradiotherapy (a total of 70 Gy delivered in 33 fractions).

Weekly and triweekly cisplatin-based concurrent chemoradiotherapy (CCRT) have been used in the treatment of nasopharyngeal carcinoma (NPC). This study aimed to compare the benefits and risks between the two treatments. We systematically searched electronic databases for prospective and retrospective clinical studies of NPC patients who received weekly compared with triweekly cisplatin-based CCRT.

Background: The aim of this study was to evaluate the efficacy of induction chemotherapy (IC) in nasopharyngeal carcinoma (NPC) patients with moderate-risk treated with intensity-modulated radiotherapy (IMRT).

Methods: We retrospectively assessed 506 patients with T1-2N1M0 or T3-4N0-1M0 NPC (according to the 2010 UICC/AJCC staging system) who received concurrent chemoradiotherapy (CCRT) with or without IC at a single center in China between 2005 and 2010. Survival outcomes were compared between the IC + CCRT and CCRT groups using the Kaplan-Meier method, Log-rank test and a Cox regression model.

Objective: To observe the effect of electroacupuncture (EA) preconditioning on the expression of liver protein kinase 1 (LKB1), adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK) and 6-phosphofructo-2-kinase (PFK2) in cardiomyocytes of rats with acute myocardial ischemia (AMI), so as to explore its mechanisms underlying cardioprotective effect.

Methods: Thirty male Wistar rats were randomly divided into sham-operation, model and EA pretreatment groups (=10 rats per group). The AMI model was established by ligation of the left anterior descending branch of coronary artery.

: First degree family history of cancer is associated with developing esophageal cancer and sparse data is about the impact on poor survival among established esophageal squamous cell cancer (ESCC) patients. In this study, we investigated the prognoses of patients with ESCC with a family history. : A total of 479 ESCC patients were retrospectively enrolled from a Southern Chinese institution.

Cigarette smoking is associated with the development of esophageal squamous cell carcinoma (ESCC); however, the influence of smoking on survival of patients with ESCC receiving radiotherapy, with or without chemotherapy, has remained elusive. The present study retrospectively analyzed 479 patients with ESCC from southern China who were categorized based on their smoking history (never, previous or current). To consider the cumulative effect of smoking, the number of pack years (PYs) was used as a representative variable.

Background And Objective: Clinical trials on docetaxel plus cisplatin (DDP) (TP regimen) in treating nasopharyngeal carcinoma (NPC) are still uncertain due to limited samples. This study was to compare the short-term efficacy and toxicity of induction chemotherapy with TP regimen followed by concurrent chemoradiotherapy with TP regimen versus DDP in treating locally advanced NPC.

Methods: Fifty-seven patients with stage T3-4N2-3M0 NPC diagnosed pathologically from December 2005 to December 2006 were randomized into TP group (30 patients) and DDP group (27 patients).

Background & Objective: Docetaxel and cisplatin (DDP) are effective drugs for head and neck tumors. Stage II-III clinical trial of TP regimen (docetaxel combined DDP) for head and neck tumors has completed. This study was to compare the efficacy and toxicity of TP regimen and PF regimen [DDP combined 5-fluorouracil (5-FU)] in treating nasopharyngeal carcinoma (NPC), to provide a new chemotherapeutic regimen for NPC.

Background & Objective: Nasopharynx is a commonly involved site of non-Hodgkin's lymphoma (NHL), but the differences of clinical characteristics, prognosis, and treatment strategy between B-cell and NK/T-cell nasopharyngeal NHL have seldom been reported. This study was to investigate the clinical manifestations and treatment outcomes of primary B-cell and NK/T-cell nasopharyngeal NHL at early stage, and evaluate the prognostic differences, so as to provide evidences for treatment optimization.

Methods: Clinical data of 80 patients with previously untreated nasopharyngeal NHL at early stage, admitted from May 1987 to Nov.

Background & Objective: The influence of age on treatment outcome and survival of nasopharyngeal carcinoma (NPC) patients has seldom been reported. This study was to explore the clinical characters of aged NPC patients.

Methods: A total of 754 patients with histopathologically proven NPC from Jan.
