Materials and methods: This is a single-institution, retrospective analysis examining disease free and overall survival and toxicity after hypofractionated radiation therapy in a patient population 75 years and older diagnosed with stage IA or IB (T1/T2 N0) NSCLC. Between 1991 and 2005, a total of 33 such patients were identified with a median age of 79 years. Patients were treated with a median total dose of 7000 cGy using median daily dose fractions of 250 cGy. Analysis of competing risks (local failure, distal failure or death as the first event) was performed and cumulative incidence functions (CIF) were estimated. Results: The median length of follow-up was 19.8 months (range: 4.3 - 103.8 months). Of the 33 patients treated, 21 (63.6% of total) had no evidence of disease recurrence on follow-up imaging over the course of the study. Of the 12 patients with disease recurrence, 6 (18.2% of total) had local failure as the first event and 6 (18.2% of total) had distant metastasis as the first event. Analysis of competing risks showed that at 5 years, the probability of local failure as the first detected event was 19.5% (95%CI: 7.6%, 35.6%);the probability of distal failure as the first detected event was 21.5% (95%CI: 7.9%,39.4%);and the probability of death without recording a failure was 44.1% (95%CI: 26.1%, 60.7%). There were no treatment related deaths reported. Conclusions: Elderly patients diagnosed with stage I non-small cell lung cancer may safely be offered hypofractionated radiotherapy as an effective option with curative intent.展开更多

This study analyzed the clinical outcomes using VATS segmentectomy for stage I NSCLC patients to explore the safety and efficacy of VATS segmentectomy for la NSCLC. Methods Retrospective review was conducted of patients who underwent VATS segmentectomy for clinical stage I NSCLC at Shanghai Chest Hospital between November 2009 and May 2012. VATS segmentectomy was performed on 36 patients. Analyses of the patient group were performed on patient demographics and clinical characteristics, intraoperative parameters, complications, and postoperative survival. Results Thirty-five of thirty-six patients underwent VATS segmentectomy with only one conversion to open thoracic surgery. There was one peri-operative mortality from the segmentectomy group and all other patients are alive with a median follow up of 327 days. The mean volume of chest tube drainage after operation for segmentectomy was 1021.4 ml. Among other parameters, the mean blood loss was 162.5 ml （50.0-1600.0 ml）, the mean operation time 124.8 minutes （75.0-271.0 minutes）, chest tube duration 4.1 days （2-8 days）, and the mean length of hospital stay 6.2 days （4-11 days）. There was one （2.8%） Iocoregional recurrence after segmentectomy. Two patients successfully underwent bilateral segmentectomies and are still disease free. Conclusion For patients with stage I NSCLC, VATS segmentectomy offers a safe and equally effective option and can be applied to complicated operations such as bilateral segmentectomy.展开更多
