Do Hospital Characteristics Influence Cancer-Specific Survival for Early Stage Lung Cancer?

Background— Quality of oncologic outcomes is of paramount importance in the care of patients with non-small cell lung cancer (NSCLC). We sought to evaluate the relationship of hospital volume for lobectomy on cancer-specific survival in NSCLC patients treated in California, as well as the influence of Committee on Cancer (CoC) accreditation. Methods— The California Cancer Registry was queried from 2004–2011 for cases of Stage I NSCLC and 8,345 patients were identified. Statistical analysis was used to determine prognostic factors for cancer-specific survival. Results— 7,587 patients were treated surgically. CoC accreditation was not significant for cancer-specific survival, but treatment in high volume centers was associated with longer survival when compared to low and medium volume centers (HR 1.77, 1.474–2.141 and HR 1.23, 1.058– 1.438). Conclusions— These data suggest that surgical treatment in high volume hospitals is associated with longer cancer-specific survival for early-stage NSCLC, but that CoC accreditation is not. overall survival Kaplan-Meier method hospital CoC Log-rank tests to examine differences in regression survival
