BackgroundThe interval between surgery and adjuvant chemotherapy (AC) is a predictive factor of survival in high-risk colon cancer (CC). This study aimed to evaluate the impact of intraoperative sentinel lymph node (SLN) analysis using the one-step nucleic acid amplification (OSNA) technique on the time interval between surgery and AC.MethodsWe performed a prospective study analyzing 56 consecutive patients who had surgery for CC between July 2012 and October 2014, including 20 patients needing AC. SLN status was determined intraoperatively in 17 patients in the OSNA group; when positive, a portacath (PAC) was placed during the procedure for upcoming AC. In the remaining patients, we proceeded without SLN status determination and the PAC was installed after definitive histopathological analysis of the specimen if needed.ResultsThere was no difference between the groups regarding cancer staging, duration of hospitalization (7.5 days in the OSNA group and 10 days in the control group, p = 0.43) and major complications (20% vs 30% respectively, p = 0.55). The time interval between surgery and adjuvant chemotherapy was significantly shorter in the OSNA group at 35 (±8) days vs 67 (±36) days (p = 0.021).ConclusionSLN status determination by the OSNA technique is safe, feasible and could significantly reduce time between surgery and adjuvant chemotherapy in a pilot study.
