ABSTRACT
BACKGROUND:
Standard of care for locally advanced rectal cancer (LARC) (stage II/III) includes preoperative chemoradiation (CRT) followed by resection and adjuvant chemotherapy. Total neoadjuvant therapy (TNT) is a new treatment paradigm that delivers systemic therapy prior to CRT aimed at improving outcomes for high-risk patients. Here we analyzed the national cancer database (NCDB) comparing short-term post-operative outcomes between patients receiving TNT and CRT.METHODS:
The NCDB was queried to identify patients with LARC between the 2004 and 2014 treated with TNT or CRT. Primary outcomes included post-operative 30-day mortality and readmissions between TNT and CRT which were analyzed via logistic regression. Secondary outcomes included post-operative length of stay (LOS) and OS which were compared with two-tailed t-test and Kaplan-Meier with log rank testing, respectively.RESULTS:
A total of 9066 patients met inclusion criteria with a median age at diagnosis that was 57 years (IQR, 19-65); 62.3% were male and 87.8% white. Neoadjuvant therapy consisted of either standard CRT (97.2%) or TNT (2.8%). Patients treated at academic programs and those with N1 [p < 0.001, OR 2.34, 95%CI 1.71-3.19] or N2 [p < 0.001, OR 3.29, 95%CI 2.19-4.94] disease were associated with increased utilization of TNT. TNT was not significantly associated with either 30-day mortality (p = 1.0) or readmissions (p = 0.82). Further, there was no significant difference identified between CRT and TNT for hospital LOS or OS (p = 0.18).CONCLUSION:
This large-scale analysis of patients with LARC demonstrates increased utilization of TNT in patients harboring node-positive disease. Further, TNT does not appear to increase 30-day post-operative mortality, readmissions, or hospital LOS.Palavras-chave
