Histology-related variation in the treatment and survival of patients with lung carcinoma in Canada.

摘要: Objectives: The aim of the study was to examine histologic differences in lung cancer treatment and survival, define recent survival trends Ottawa, Canada. Methods: From 1994 2000, 3237 patients with invasive were registered at Ottawa Regional Cancer Centre (ORCC) followed up 31 December 2001. Five-year relative rates (RSRs) excess risks (RERs) dying calculated by stage dominant initial modalities for major cellular histologies using a model. Results: overall 5-year rate 14%, female had significantly better survival. Patients I II non-small cell (NSCLC) who treated surgery alone more likely survive (5-year RSRs 72 48%, respectively) than those received other treatments. III NSCLC 9% after chemotherapy plus radiotherapy, whereas IV only 2 years In cases limited-stage small (SCLC), radiotherapy chemotherapy. Conclusions: relatively superior surgical implies that considerable number have potential be successfully. poor suggests need national public health emphasis on prevention, improved screening early diagnosis, treatment.
