title: Enterocutaneous fistula in cancer patients: etiology, management, outcome, and impact on further treatment.
abstract: Enterocutaneous fistulae that develop in patients with cancer represent a difficult management situation, which is often complicated by prior treatment including surgery, radiation therapy, and chemotherapy. A fistula may in turn delay potentially beneficial treatment of the underlying malignancy. To provide a better understanding of this problem, we reviewed the National Institutes of Health experience with enterocutaneous fistulae in adult patients with cancer. The medical records of patients with cancer who developed a fistula from the gastrointestinal tract during the period 1980 through 1994 were reviewed. Etiology, management, outcome, and impact on further treatment were assessed. Twenty-five patients with gastrointestinal fistulae were identified. The most common primary tumor site was the colon/rectum in males and the ovary in women. The majority of patients had metastatic disease at diagnosis and a history of prior therapy and presented with anorexia and weight loss. The fistula was usually single, most commonly developed from the jejunum/ileum (13 patients) or colon/rectum (6 patients), and occurred postoperatively after procedures on the small bowel (10 patients) or colon (8 patients). Malnutrition and sepsis developed in 60 per cent of patients. Thirty-day mortality was 16 per cent and correlated with prior radiation therapy, location and output from the fistula, and hypoalbuminemia. An enterocutaneous fistula negatively impacted on the provision of further therapy for the majority of patients (63%). Enterocutaneous fistula in the patient with cancer occurs most frequently in the setting of extensive prior therapy and is associated with prolonged morbidity. Identification of high-risk patients and early management of fistulas once they develop may prevent delays in subsequent cancer therapy and decrease morbidity.
