e16025 Background: Clinical trials have shown that CRT improves survival compared to RT alone in muscle invasive bladder cancer. We describe uptake of CRT and outcomes in routine practice. Methods: Electronic treatment records were linked to the population-based Ontario Cancer Registry to identify all patients treated with curative intent RT for bladder cancer in Ontario 1999-2013. Practice patterns were described in three eras: 1999-2003, 2004-2008, 2009-2013. Modified Poisson regression was used to analyze factors associated with use of CRT. Cox model and propensity score analysis were used to explore the association between CRT and overall (OS) and cancer-specific survival (CSS). Results: 1398 patients underwent curative intent RT during 1999-2013; median age was 79 and 75% (1050/1398) were male. Use of CRT increased over time: 33% (135/409) in 1999-2003, 35% (170/482) in 2004-2008, 46% (232/507) in 2009-2013 (p < 0.001). Among the 80% (431/537) of CRT cases with available drug details, the most common regimens were single-agent Cisplatin (57%, 245/431), single-agent Carboplatin (31%, 133/431) and 5-FU/Mitomycin (4%, 19/431). Factors associated with CRT include younger age (p < 0.001), male sex (p = 0.027), and lower co-morbidity (p < 0.001). There were large regional differences in use of CRT (range 14% to 85%, p < 0.001). Five year OS, CSS, and cystectomy-free survival rates among CRT cases were 34% (95%CI 30%-39%), 45% (95%CI 40%-50%), and 30% (95%CI 26%-34%). On adjusted analyses CRT was associated with superior survival compared to RT alone (OS HR 0.68, 95%CI 0.60-0.70; CSS HR 0.64, 95%CI 0.54-0.76). These results were consistent on propensity score analysis. There was a non-significant trend towards improved survival among all treated cases in 2009-2013 compared to 1999-2003 irrespective of chemotherapy delivery (OS HR 0.86, 95%CI 0.74-1.01; CSS HR 0.82, 95%CI 0.67-1.01). Conclusions: Although there has been substantial uptake of CRT in routine practice, utilization rates vary widely by region. CRT is associated with superior survival compared to RT alone and its uptake corresponded to a temporal trend towards improved survival among all treated cases in the general population.

Abstract OBJECTIVES To evaluate the postoperative complications and 30-day mortality rates associated with neoadjuvant chemotherapy before major anatomic lung resections registered in the European Society of Thoracic Surgeons (ESTS) database. METHODS Retrospective analysis on 52 982 anatomic lung resections registered in the ESTS database (July 2007–31 December 2017) (6587 pneumonectomies and 46 395 lobectomies); 5143 patients received neoadjuvant treatment (9.7%) (3993 chemotherapy alone and 1150 chemoradiotherapy). To adjust for possible confounders, a propensity case-matched analysis was performed. The postoperative outcomes (morbidity and 30-day mortality) of matched patients with and without induction treatment were compared. RESULTS 8.2% of all patients undergoing lobectomies and 20% of all patients undergoing pneumonectomies received induction treatment. Lobectomy analysis: propensity score analysis yielded 3824 pairs of patients with and without induction treatment. The incidence of cardiopulmonary complications was higher in the neoadjuvant group (626 patients, 16% vs 446 patients, 12%, P < 0.001), but 30-day mortality rates were similar (71 patients, 1.9% vs 75 patients, 2.0%, P = 0.73). The incidence of bronchopleural fistula and prolonged air leak >5 days were similar between the 2 groups (neoadjuvant: 0.5% vs 0.4%, P = 0.87; 9.2% vs 9.9%, P = 0.27). Pneumonectomy analysis: propensity score analysis yielded 1312 pairs of patients with and without induction treatment. The incidence of cardiopulmonary complications was higher in the treated patients compared to those without neoadjuvant treatment (neoadjuvant 275 cases, 21% vs 18%, P = 0.030). However, the 30-day mortality was similar between the matched groups (neoadjuvant 68 cases, 5.2% vs 5.3%, P = 0.86). Finally, the incidence of bronchopleural fistula was also similar between the 2 groups (neoadjuvant 1.8% vs 1.4%, P = 0.44). CONCLUSIONS Neoadjuvant chemotherapy is not associated with an increased perioperative risk after either lobectomy or pneumonectomy, warranting a more liberal use of this approach for patients with locally advanced operable lung cancer.
