Objective
To assess treatment patterns, outcomes, and costs for bowel obstruction in ovarian cancer.
Methods/materials
All patients with stage II–IV ovarian cancer who were admitted for bowel obstruction ≥6 months after cancer diagnosis from 2000–2011 were identified from the Surveillance, Epidemiology, and End Results registry (SEER)–Medicare database. Management strategies and outcomes of bowel obstruction were compared.
Results
Among 1,397 women with bowel obstruction, 562 (40%) underwent surgery and 154 (11%) had a gastrostomy or jejunostomy (G/J) tube placed. 34% of patients who underwent surgery subsequently received chemotherapy, compared to 8% of those managed with a G/J tube (OR 4.8, 95% CI 2.7-8.8). 30-day complications were higher for patients in the surgery group compared to the tube group (69% vs 46%, OR 2.5, 95% CI 1.8-3.7), as were mean adjusted 30-day total costs ($28,872 vs $18,528, p<.001). Median survival was greater for women who underwent surgery compared to those who had a G/J tube (5.3 vs 1.2 months; adjusted HR 0.31, 95%CI 0.25-0.38). The median survival of patients in whom surgical correction failed and required G/J tube placement during the same inpatient admission was 2.6 months. Women who received post-intervention chemotherapy had improved survival compared to those who did not in both the surgery (17.0 vs 2.8 months, p<.001) and G/J tube groups (5.7 vs 1.0 months, p<.001).
Conclusions
In women with ovarian cancer who develop bowel obstruction, surgery may benefit a subset of patients, likely related to the ability to receive subsequent chemotherapy. Efforts to identify those who derive no benefit may reduce unnecessary laparotomy, along with its associated complications and costs. Given this population’s limited survival, patient preferences should be evaluated in future studies assessing the management of bowel obstruction.
