Impact of American College of Surgeons Oncology Group Z11 on surgical training at an academic cancer center.

ABSTRACT: The application of the American College of Surgeons Oncology Group Z0011 trial (Z11) has resulted in fewer completion axillary lymph node dissections (ALNDs) for select patients. We hypothesize that the application of Z11 may result in fewer ALND cases for surgeons in training.In the setting of an academic cancer center incorporating Z11 into routine practice, we compared the total number of ALND performed in a pre-Z11 period (January 2007-April 2011, 52 mo) and post-Z11 period (April 2011-February 2014, 34 mo). We also identified the number of patients in the post-Z11 era in whom ALND was omitted as a result of Z11. Clinical and pathologic characteristics among these groups were analyzed.A total of 279 and 191 ALNDs were performed in the pre-Z11 and post-Z11 groups, respectively. Variables were similar among these groups with respect to demographics, tumor characteristics, and surgeries performed. There was no difference in the monthly rates of ALND between groups-5.37 cases/mo (pre-Z11) and 5.62 cases/mo (post-Z11), P = 0.52. We identified a total of 53 patients for whom ALND was omitted due to Z11 application in the post-Z11 period, representing a potential 21.7% decrease (53/191 + 53) in the number of ALNDs in this period.Although the application of Z11 could potentially impact surgical training with a 21.7% decrease in ALND cases (53/191 + 53), the surgical case volume at an academic cancer center absorbs this decrease and maintains consistent levels of training for ALND.

Project description:BACKGROUND:Given the rarity of pediatric surgical disease, it is important to consider available large-scale data resources as a means to better study and understand relevant disease-processes and their treatments. The Military Health System Data Repository (MDR) includes claims-based information for >?3 million pediatric patients who are dependents of members and retirees of the United States Armed Services, but has not been externally validated. We hypothesized that demographics and selected outcome metrics would be similar between MDR and the previously validated American College of Surgeons National Surgical Quality Improvement Program-Pediatric (NSQIP-P) for several common pediatric surgical operations. METHODS:We selected five commonly performed pediatric surgical operations: appendectomy, pyeloplasty, pyloromyotomy, spinal arthrodesis for scoliosis, and facial reconstruction for cleft palate. Among children who underwent these operations, we compared demographics (age, sex, and race) and clinical outcomes (length of hospital stay [LOS] and mortality) in the MDR and NSQIP-P, including all available overlapping years (2012-2014). RESULTS:Age, sex, and race were generally similar between the NSQIP-P and MDR. Specifically, these demographics were generally similar between the resources for appendectomy (NSQIP-P, n?=?20,602 vs. MDR, n?=?4363; median age 11 vs. 12?years; female 40% vs. 41%; white 75% vs. 84%), pyeloplasty (NSQIP-P, n?=?786 vs. MDR, n?=?112; median age 0.9 vs. 2?years; female 28% vs. 28%; white 71% vs. 80%), pyloromyotomy, (NSQIP-P, n?=?3827 vs. MDR, n?=?227; median age 34 vs. <?1?year, female 17% vs. 16%; white 76% vs. 89%), scoliosis surgery (NSQIP-P, n?=?5743 vs. MDR, n?=?95; median age 14.2 vs. 14?years; female 75% vs. 67%; white 72% vs. 75%), and cleft lip/palate repair (NSQIP-P, n?=?6202 vs. MDR, n?=?749; median age, 1 vs. 1?year; female 42% vs. 45%; white 69% vs. 84%). Length of stay and 30-day mortality were similar between resources. LOS and 30-day mortality were also similar between datasets. CONCLUSION:For the selected common pediatric surgical operations, patients included in the MDR were comparable to those included in the validated NSQIP-P. The MDR may comprise a valuable clinical outcomes research resource, especially for studying infrequent diseases with follow-up beyond the 30-day peri-operative period.
