  • Clinical characteristics and prognosis of resectable esophageal small cell carcinoma after surgical resection

    ObjectiveTo investigate the clinical characteristics and prognosis of resectable esophageal small cell carcinoma after surgical resection.MethodsA retrospective study of patients with resectable esophageal small cell carcinoma undergoing surgical resection from January 2009 to June 2015 in the Department of Thoracic Surgery, Sichuan Provincial Fourth People's Hospital and Department of Thoracic Surgery, West China Hospital of Sichuan University was performed. Survival analysis was conducted by Kaplan-Meier analysis and log-rank test. Cox regression model was used for identifying independent prognostic factors.ResultsA total of 53 patients with resectable esophageal small cell carcinoma were included for analysis. The mean age was 58.4 ± 8.3 years and there were 42 male patients and 11 female patients. Forty-two patients were diagnosed as pure esophageal small cell carcinoma while 11 patients were diagnosed with mixed esophageal small cell carcinoma, who were all mixed with squamous cell carcinoma. Most of the esophageal small cell carcinomas were located in the middle (58.5%) and lower (32.1%) segments of the esophagus. Thirty patients (56.6%) were found to have lymph node metastasis, and 7 patients (13.2%) were found to have lymphovascular invasion. According to the 2009 TNM staging criteria for esophageal squamous cell carcinoma, there were 12 patients with stage Ⅰ disease, 19 patients with stage Ⅱ disease, and 22 patients with stage Ⅲ disease. Most of the patients underwent left thoracotomy with two-field lymphadenectomy. Postoperatively, only twenty-two patients (41.5%) received adjuvant chemoradiotherapy. The median survival time of these patients was 20.1 months, and the 1- and 3-year survival rate was 75.5% and 33.1%, respectively. For prognosis, age, gender, pathological type, tumor location, and lymphovascular invasion had no significant impact on long-term survival of these patients. However, TNM stage (1 year survival rate: stage Ⅰ: 91.7%; stage Ⅱ: 78.9%; stage Ⅲ: 63.6%; P=0.004) and postoperative adjuvant therapy (1 year survival rate: 81.8% vs. 71.0%; P=0.005) had significant impact on the survival of patients with esophageal small cell carcinoma. In multivariate analysis, TNM stage and postoperative adjuvant therapy were independent prognostic factors for long-term prognosis of patients with esophageal small cell carcinoma.ConclusionEsophageal small cell carcinoma is very rare, with high malignancy and poor prognosis. For patients with resectable esophageal small cell carcinoma, the TNM staging system of esophageal squamous cell carcinoma can be used to direct the choice of treatment options. For early stage esophageal small cell carcinoma (stage Ⅰ/Ⅱ), surgery plus postoperative adjuvant chemoradiotherapy can be the prior therapeutic choice, while for locally advanced esophageal small cell carcinoma (stage Ⅲ), chemoradiotherapy should be the preferred treatment.

  • Recent advancement of researches on surgery for esophageal cancer

    Esophageal cancer is one of the most common malignant cancers with a poor prognosis. For those non advanced stage patients, multi-disciplinary treatment based on surgery remains to be an important treatment strategy. Even though surgical techniques have developed rapidly, it still remains controversies in the surgical treatment of esophageal cancer. This review aimed to summarize and discuss those hot topics about the surgery of esophageal cancer, including surgical approaches of esophagectomy, anastomosis, lymphadenectomy, minimally invasive esophagectomy, and neoadjuvant therapy, hoping to provide evidence and perspectives in the surgical treatment for esophageal cancer.

  • Research advances in lymph node dissection in non-small cell lung cancer

    Lymph node metastasis in non-small cell lung cancer is an independent risk factor for poor prognosis. Resection of lymph nodes can improve the prognosis of patients. Although surgical techniques are progressing, there is still much controversy about the way of lymph node resection for non-small cell lung cancer. The research progress of hot topics such as the choice of lymph node resection methods for non-small cell lung cancer is discussed and summarized.
