Data Source
The SEER-Medicare dataset includes patient demographics, cancer diagnosis and treatment-related information, and cause of death linked to Medicare data. The Medicare linkage provides Medicare hospital, outpatient, physician, home health, and hospice claims. Medicare insures approximately 97% of people 65 years of age and older in the United States, allowing approximately 93% of that population in the SEER registry to be linked to the Medicare enrollment file.14,15 The current release contains
Patients
A total of 4307 patients undergoing lobectomy were identified (thoracoscopy: n = 3881; robotic-assisted: n = 426). Patient demographics, comorbidities, and tumor characteristics are listed in Table 1 for the matched cohort and in Supplemental Table 2 for the full cohort. Patients undergoing thoracoscopic and robotic-assisted lobectomy were similar in age, sex, median income, and the site of surgery. Patients undergoing thoracoscopic lobectomy were less likely to have coronary artery disease and
Comment
Our propensity-matched analysis of long-term OS and CSM after lobectomy suggests that there are no differences in long-term outcomes in patients undergoing robotic-assisted or thoracoscopic lobectomy. These minimally invasive lobectomy approaches also have similar in-hospital outcomes with the exception of mortality, which was higher in the thoracoscopic group.
Our results differ from those published from multiinstitutional case series, while supporting other single-institution case series (
