Effect of a colorectal bundle in an entire healthcare region in Switzerland: results from a prospective cohort study (EvaCol study).

Introduction: Standardization has the potential to serve as a measure to mitigate complication rates. The objective was to assess the impact of standardization by implementing a colorectal bundle (CB), which comprises nine elements, on the complication rates in left-sided colorectal resections.

Patients And Methods: This prospective, multicentre, observational, cohort trial was conducted in Switzerland at nine participating hospitals.

Evaluation of the Introduction of a Colorectal Bundle in Left Sided Colorectal Resections (EvaCol): Study Protocol of a Multicentre, Observational Trial.

Purpose: Overall complication and leak rates in colorectal surgery showed only minor improvements over the last years and remain still high. While the introduction of the WHO Safer Surgery Checklist has shown a reduction of overall operative mortality and morbidity in general surgery, only minor attempts have been made to improve outcomes by standardizing perioperative processes in colorectal surgery. Nevertheless, a number of singular interventions have been found reducing postoperative complications in colorectal surgery.

Minimal residual disease in breast cancer and gynecological malignancies: phenotype and clinical relevance.

In breast cancer, about 35% of patients without any clinical signs of overt distant metastases already have disseminated tumor cells in bone marrow aspirates at the time of primary therapy. A significant prognostic impact of these disseminated tumor cells has been shown by many international studies: patients with tumor cells in their bone marrow have a significantly worse prognosis than those without them. Even in malignancies where the skeletal system is not a preferred location for distant metastasis, such as ovarian cancer, early presence of minimal residual disease (MRD) is correlated with poor patient outcome.
