Background and purpose:Life expectancy has continuously improved in recently years with the development of medical level. In 2012, the amount of people who were above 60 years old has reached 810 million and account for 11% of worldwide population. The worldwide population shift towards older ages will inevitably lead to more elderly patients being diagnosed with non-small cell lung cancer (NSCLC). It still remains controversial whether sublobar resection is effective in such cases. In order to solve this question, we need to understand the clinical characteristics of these tumors. Methods:From 2006 to 2012, a total of 310 patients with NSCLC who were above 65 years old underwent surgical resection in Department of Thoracic Surgery, the First Afifliated Hospital of China Medical University and the Second Department of Thoracic Surgical Oncology, Jilin Province Tumor Hospital. The clinical data were retrospectively analyzed in sex, stage, histology, smoking status, smoking amount, drinking status, surgical approaches, multimodality therapy and overall survival. Survival was analyzed by Kaplan–Meier method and log-rank test. Results:There were 256 (82.6%) elderly patients who underwent standard lobectomies and 54 (17.4%) patients who underwent sublobar resections. The overall 5-year survival rate was 52.9%. Patients with different surgical approaches (lobectomy and sublobar resection) had nearly the same 5-year survival rates (60.5%vs 60.8%, P=0.381). The prognosis were signiifcantly inlfuenced by gender (P=0.024), stage of disease (P=0.028), smoking status (P=0.034) and smoking amount (P=0.028). The multivariate Cox proportional hazards analysis revealed that the smoking status was associated with the hazard ratio of 1.660 (1.058-2.606;P=0.028). Conclusion:In elderly NSCLC patients, sublobar resection is considered to be an appropriate treatment in comparison with lobectomy, as this procedure provides an equivalent long-term survival. The survival of elderly patients with lung cancer is closely related to the smoking status.

Objective To analyze the clinical features of subacute thyroiditis (SAT ) manifested as fever of unknown origin (FUO) for early diagnosis .Methods The clinical and laboratory data were retrospectively reviewed for 20 SAT patients manifected as fever of unknown origin from October 2009 to February 2013 .Results A total of 20 patients were finally diagnosed as subacute thyroiditis ,about 3% of the 661 FUO patients .Only 5 SAT patients had complained of angina or pain in the anterior region of neck .Thyroid enlargement and tenderness were observed in 14 SAT cases .Elevated serum thyroid hormone and a very low serum level of thyroid stimulating hormone were seen in 17 patients with SAT .Ultrasound scan of thyroid showed inhomogenous hypoechongenic texture in 14 patients .99m Tc pertechnetate scan of thyroid showed extremely low radiopharmaceutical uptake in all the 20 cases .All patients had received antibiotic treatment prior to admission .Conclusions Subacute thyroiditis is an uncommon but important cause of FUO .Detailed history ,physical examination and laboratory evaluation can help minimize the chance of misdiagnosis and unnecessary antibiotic therapy .
