A colostomy for large bowel obstruction at the end of life: What do patients gain from palliative surgery?

OBJECTIVES: Malignant large bowel obstruction (LBO) is a frequent complication affecting women with gynecologic cancers and is an indication for emergent surgery. However, the life expectancy and subsequent medical care utilization are unknown. We sought to estimate overall survival (OS) following colostomy and describe subsequent healthcare utilization among patients with advanced gynecologic malignancies. METHODS: We conducted a retrospective analysis of patients with advanced gynecologic cancers who underwent colostomy with palliative intent due to LBO at our institution between March 2014 and January 2023. Summary statistics were used to describe the clinical and demographic characteristics of the study population. OS was estimated using the Kaplan-Meier method, and we defined healthcare utilization at the end-of-life using criteria published by the National Quality Forum. RESULTS: A total of 78 patients were included. The median age at the time of surgery was 61 (range: 34-83), and most patients had recurrent ovarian, fallopian tube, or primary peritoneal cancer (n = 51, 65.4%), followed by cervical cancer (n = 16, 20.5%), and uterine cancer (n = 10, 12.8%). The median Charlson comorbidity index was 3 and median postoperative length of stay was five days (range: 1-26). The median follow-up for all patients was 4.5 months (range: 0.07-46.2), and the median OS was 4.5 months (95% CI: 2.9-6.0), including 12 patients (15.4%) with <30-day OS and 21 (26.9%) with <60-day OS. In the last 30 days of life, 62.7% of patients were re-admitted to the hospital, 53.0% were seen in the emergency department, and 18.5% were admitted to an intensive care unit. CONCLUSIONS: A significant proportion of patients died within 60 days of surgery, and many had high healthcare utilization at the end of life.

Cascade genetic testing: an underutilized pathway to equitable cancer care?

The Precision Medicine Initiative was launched upon the potential of genomic information to tailor medical care. Cascade genetic testing represents a powerful application of precision medicine and involves the process of familial diffusion or the "cascade" of genomic risk information. When an individual (proband) is found to carry a cancer-associated germline pathogenic mutation, the information should be cascaded or shared with at-risk relatives. First degree relatives have a 50% likelihood of carrying the same cancer-associated mutation. This process of cascade testing offers at-risk relatives the opportunity for genetic testing and, for those who also carry the cancer-associated mutation, genetically targeted primary disease prevention through intensive cancer surveillance, chemoprevention and risk-reducing surgery, reducing morbidity and preventing mortality. Cascade testing has been designated by the Centers for Disease Control and Prevention as a Tier 1 genomic application for hereditary breast and ovarian cancer. In this manuscript we describe a cascade genetic testing and in particular focus on its potential to provide necessary care to medically underserved and vulnerable populations.
