Background: Non-small cell lung cancer is the most common type of lung cancer. It usually grows and spreads more slowly than small cell lung cancer. Objective: To describe clinical characteristics and the TNM staging of non-small cell lung cancer. Subjects and method: It was a prospective study on clinical characteristics and the TNM staging of 53 patients with non-small cell lung cancer in Bach Mai Hospital from January 2005 to June 2005. Results and conclusions: The most common age was over 40, accounting for 92.5%, male/female (2.5/1). 64.2% of cases with smoking history (97.1% for men and 2.9% for women). 79.4% of patients had smoked over 20 years. The concordance of diagnosis between the previous hospitals and Bach Mai hospital was 34.6%. The most common clinical symptoms at the time of diagnosis were chest pain, prolonged cough, haemoptysis, weight lost and pleural effusion syndrome. Basing on the 1997 International Staging System of Non-Small Cell Lung Cancer, we have found that T4 in 64.2%, N(+) 64.2% and metastasis in 32.1%. IIIB and IV stage in 75.5%, patients with IA to IIIA stages being able to be operated was 24.5% of cases. 92.5% of patients were over 40 years old; male/female: 2.5/1. 79.4 of patients had smoked cigarette over 20 years.

OBJECTIVETo investigate the clinicopathological characteristics of anthracosilicosis complicated with lung cancer.

METHODSTissue specimens from 16 autopsy cases of 0(+) anthracosilicosis complicated with lung cancer were retrospectively studied by hematoxylin-eosin, histochemical, and immunohistochemical staining.

RESULTSAll of 16 patients were male. The patient's age ranged from 46 to 57 years (average: 52.8 years). The dust-exposure time were over 25 years. The pneumoconiosis and dust fibrosis of different degrees in the lung were found. The positive detected rate of coal silicotic nodules was 93.75% (15/16). Among 16 cases of lung cancer, there were 5 cases of squamous cell carcinoma, and 5 cases of small cell undifferentiated carcinoma, 3 cases of bronchioloalveolar carcinoma, 2 cases of adenocarcinoma and 1 case of adenosquamous carcinoma. The typical pathological changes of anthracosilicosis complicated with lung cancer were: the cancer tissue was located at the side of coal dust fibrous focus and fibrosis lesion, or mixte with silicotic lesion. CK, EMA and CEA were positively expressed in most of the tumor cells, while vimentin was positive in the fibrocyte of dust fibrosis.

CONCLUSIONSThe occurrence of some lung cancer may be related with fibrosis. The dust-exposed workers can suffer from lung cancer which is histologically identical to the general lung tumor. PCNA and Ki67 may be a prognostic index for anthracosilicosis with lung cancer, while vimentin may be a marker for the examination of dust fibrosis in anthracosilicosis.

OBJECTIVETo define the clinical features of postoperative chylothorax for lung cancer (PCLC), and to compare them with those for esophageal cancer (PCEC).

METHODWe retrospectively analysed clinical characteristics of 12 patients with chylothorax among 4 084 patients receiving resection of lung cancer, as well as 52 in 4 479 patients having resection of esophageal cancer since 1985 at our hospital.

RESULTSThe incidence of PCLC was 0.29% and that of PCEC was 1.16%. The percentage of diagnosis confirmed within 4 postoperative days was 33.3% for PCLC, and 76.9% for PCEC. The rate of typical chylous pleural effusion was 83.3% for PCLC, and 5.8% for PCEC. Symptoms and signs of PCLC were much milder than those of PCEC. The re-operation rate was 16.7% for PCLC, and 96.2% for PCEC. All patients were discharged uneventfully.

CONCLUSIONThe incidence, causes, clinical manifestations, diagnosis, and treatment of PCLC is different from those of PCEC.

Serum autoantibody markers have the advantages of easy specimen acquisition, simple detection technology and dynamic real-time monitoring. With the wide application of immune checkpoint inhibitors in the treatment of malignant tumors, autoantibody markers in predicting tumor immune checkpoint inhibitors efficacy and forecasting irAEs (immune related adverse events) show good prediction of potential. This review mainly focused on the progress of autoantibody markers in the prediction of therapeutic effect and the monitoring of irAE in tumor immunotherapy.
