Background: Surgery is considered the best treatment in Stage I non-small cell lung cancer. Local nonesurgical therapies (radiotherapy, thermoablation) are becoming valid alternative to surgery in high risk patients (poor cardiac or pulmonary function, elderly patients). Methods: Patients submitted in our Department to Microwave thermoablation (MW) were compared with a cohort of patient submitted to lung lobectomy in the same period of time, abstracted from our database with a propensity match method. The study was retrospective on data recorded prospectively. Primary endpoint was overall survival. Results: From June 2009 to October 2014 in our Department, 36 patients underwent MW for Stage I nonsmall cell lung cancer (NSCLC) or lung metastasis. From our database were abstracted 41 patients with a propensity match method, submitted to lung lobectomy. Two groups were comparable by age, diagnosis, stage and gender. MW group resulted elder than Surgery group (75,5 vs 72,2 years; p<0,001). Lesion diameter was greater in MW group (20,9 vs 26,5 cm; p<0,001). Overall survival, analyzed by actuarial survival curve, was comparable (Logrank test p¼0,2). Conclusion: In our experience, in a propensity match evaluation, lung MW thermoablation resulted non inferior than lung lobectomy in terms of overall survival. Even though surgery is still considered the first choice in
Background: From Nov. 2008 to Dec. 2013, the Japan Clinical Oncology Group (JCOG) conducted a randomized phase III trial (JCOG0707), which compared the survival benefit of UFT and S-1 for completely resected pathological (p-) stage I (T1>2 cm and T2 in the 6th TNM classification) NSCLC and a total of 963 patients were enrolled. Recently, there is a growing concern that those who participated in clinical trials are highly selected and do not represent the “real-world” population. Hereby, we conducted a multicenter observational study of patients excluded from JCOG0707 trial during the study period. Methods: We retrospectively collected and analyzed the patients’ backgrounds, tumor profiles, post-surgical treatment of the patients who underwent R0 resection of p-stage I (T1>2cm and T2 in TNM 6th) NSCLC by lobectomy or larger lung resection but were excluded from JCOG0707 from Japanese multi-centers. Results: Of the 48 institutions which took part in JCOG0707, 34 (enrolling 917 or 95.2% of all JCOG0707 patients) participated in this multicenter study, and 5006 patients were enrolled. Among them, 2617 (52.3%) patients fulfilled the eligibility criteria, but were not enrolled to JCOG0707 mainly due to patients’ decline
