[Analysis of the survival in patients after surgical resection of thoracic esophageal cancer].
To investigate the prognostic factors and influence of the number of lymph node metastases on survival and UICC-TNM classification in patients with thoracic esophageal cancer after curative resection. ⋯ The lymph node metastasis is the most important prognostic factor for thoracic esophageal cancer after resection. The major influencing factors of lymph node metastasis are the depth of invasion, length of tumor and grade of differentiation. Therefore, the lymphadenectomy along with esophagectomy and subsequently combined modality therapy against lymph node metastasis is necessary to improve the 5-year survival rate. Our proposed new classification based on number of lymph node metastases (0, 1, > or = 2 positive nodes) is more applicable because it can well reflect the correlation between lymph node metastasis and the survival, and provides evidence for the modification of the currently used UICC TNM staging system for surgically treated thoracic esophageal cancer.

To enhance the understanding of pulmonary thromboembolism (PTE) in patients with cancer. ⋯ PTE is one of the major complications and leading causes of death in patients with cancer. Of which lung cancer is most commonly, pulmonary adenocarcinoma in particular. PTE is often accompanied by DVT in the lower extremity. Risk factors may be old age, cancer progression and cancer-related operation. Other factors include long time in bed, chemotherapy and central vein catheterization, and so on. It should be watchful of PTE in cancer patients undergoing operation, especially within the first two postoperative weeks. Its clinical manifestation is often atypical. Sometimes venous thromboembolism (VTE) is the first signal of malignancy. In patients with unexplained PTE and/or DVT, attention should be paid to the possibility of malignancy. The first choice of anticoagulants is low molecular weight heparin.

[Diagnostic value of transbronchial needle aspiration combined with transesophageal endoscopic ultrasound-guided fine needle aspiration in mediastinal and pulmonary hilar lesions].
To evaluate the value of transbronchial needle aspiration (TBNA) combined with transesophageal endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in the diagnosis of mediastinal and pulmonary hilar lesions as well as in the lymph node staging (N staging) of lung cancer. ⋯ The combination of TBNA and EUS-FNA can improve the diagnostic rate for wider mediastinal and pulmlonary hilar lesions. Pathological examination of the samples obtained from the TBNA and EUS-FNA can elevate not only the rate of diagnosis but also the rate of histological classification.

[CT-guided hookwire localization of small solitary pulmonary nodules in video-assisted thoracoscopic surgery].
Video-assisted thoracoscopic surgery (VATS) provides a minimally invasive approach to resect small solitary pulmonary nodules (SSPN). The aim of this study is to evaluate the efficacy and safety of preoperative CT-guided hookwire localization for SSPN in VATS. ⋯ The preoperative CT-guided hookwire localization for small solitary pulmonary nodules is an effective and safe technique to assist VATS resection of the nodules.
