MA 13.14 - Surgical Outcomes and Survival Analysis Following Second Pulmonary Resection for Non-Small Cell Lung Cancer (ID 9374)
15:45 - 17:30 | Author(s): R. Vaghjiani
The early detection and improved survival of resected non-small cell lung cancer (NSCLC) may increase the number of patients who eventually undergo subsequent pulmonary resection. We investigated the surgical outcomes and survival of patients following second and third pulmonary resections for NSCLC.
Patients who underwent second or third pulmonary resections without induction therapy for synchronous or metachronous NSCLC (511 patients, 535 procedures, 2000-2014) were included in the analysis.
Among 535 operations, 361 (67%) were sublobar resection and 103 (19%) were performed by minimally invasive approach, with the proportion of minimally-invasive procedures increasing in recent years (Fig. 1). The majority of re-resections were performed within 4 years of the previous resection (Fig. 2). Risk regression analysis demonstrated that predicted postoperative (ppo) FEV1 (p<0.001) and same side operation (p=0.002) were independent risk factors for severe complications (CTCAE grade ≧ 3; N=45). Multivariable Cox regression analysis revealed that age at subsequent surgery, male sex, ppoDLCO, interval from prior surgery, and tumor stage were independently associated with overall survival.
In this large cohort of pulmonary re-resections for NSCLC, predicted postoperative pulmonary function tests were indictive of major complications and overall survival. Figure 1 Figure 2
