Hospital Teaching Status and Patients' Outcomes After Colon Cancer Surgery.

BACKGROUND AND OBJECTIVES: It is increasingly accepted that quality of colon cancer surgery might be secured by combining volume standards with audit implementation. However, debate remains about other structural factors also influencing this quality, such as hospital teaching status. This study evaluates short-term outcomes after colon cancer surgery of patients treated in general, teaching or academic hospitals. METHODS: All patients (n = 23,593) registered in the Dutch Colorectal Audit undergoing colon cancer surgery between 2011 and 2014 were included. Patients were divided into groups based on teaching status of their hospital. Main outcome measures were serious complications, failure to rescue (FTR) and 30-day or in-hospital mortality. Multivariate logistic regression models on these outcome measures and with hospital teaching status as primary determinant were used, adjusted for case-mix, year of surgery and hospital volume. RESULTS: Patients treated in teaching and academic hospitals showed higher adjusted serious complication rates, compared to patients treated in general hospitals (odds ratio 1.25 95% CI [1.11-1.39] and OR 1.23 [1.05-1.46]). However, patients treated in teaching hospitals had lower adjusted FTR rates than patients treated in general hospitals (OR 0.63 [0.44-0.89]). However, for all outcomes there was considerable between-hospitals variation within each type of teaching status. CONCLUSION: On average, patients treated in general hospitals had lower serious complication rates, but patients treated in teaching hospitals had more favorable FTR rates. Given the hospital variation within each hospital teaching type, it is possible to deliver excellent care regardless of the hospital teaching type.

Traumatic abdominal wall hernia, easily missed.

A 30-year-old male was diagnosed with a disruption of the musculofibrotic abdominal wall as a result of a blunt trauma 3 years after the injury. His traumatic abdominal wall hernia (TAWH) was initially missed on physical examination and computed tomography. The patient presented now with a lump in the left flank after a period of intended weight loss. Laparoscopic repair of the hernia resulted in being asymptomatic ever since. Missing a TAWH might have major consequences, such as incarceration and strangulation. Therefore, it is important to consider a TAWH after blunt abdominal trauma.

Treatment response and 5-year distant metastasis-free survival outcome in breast cancer patients after the use of MammaPrint and BluePrint to guide preoperative systemic treatment decisions.

AIM: In the prospective neoadjuvant NBREaST II study, we measured the response to preoperative treatment and 5-year survival outcome in the molecular subgroups as determined by combining the MammaPrint and BluePrint. METHODS: Between 2012 and 2016 we included 256 patients for whom MammaPrint and BluePrint were performed on pre-treatment core needle biopsies. The primary objective of the NBREaST II trial was to measure chemosensitivity or endocrine sensitivity in the molecular subgroups. Distant metastasis-free survival (DMFS), relapse-free survival (RFS) and breast cancer-specific survival (BCSS) were the endpoints for long-term follow-up. RESULTS: MammaPrint and BluePrint molecular sub-typing reclassified 9% (24/256) of tumours, reassigning more responsive patients to the HER2-Type and Basal-Type, and less responsive patients to the Luminal-Type category. Patients with Luminal A-Type tumours (n = 67, 26% of the total cohort) had a poor response when treated with neoadjuvant chemotherapy (NCT), but had the highest 5-year DMFS outcome (91.4%; 95% CI 78.6-96.7) of all molecular subgroups. Out of the IHC/FISH defined HER2+ tumours (n = 41), 37% were not classified as HER2-Type by BluePrint. Notably, in BluePrint HER2-Type tumours, we observed a higher pCR rate, whereas the 5-year DMFS was lower compared to IHC/FISH-defined HER2+ tumours. The pCR rate and 5-year outcome for patients with Basal-Type tumours were similar to IHC/FISH-defined TN tumours. CONCLUSION: These findings suggest that MammaPrint and BluePrint can predict chemosensitivity and 5-year outcomes more accurately compared to traditional pathological sub-typing, supporting informed decision-making.
