In search of the optimal outcome measure for patients with advanced cancer and gastrointestinal obstruction: A qualitative research study.
Journal of Clinical Oncology 2016 October 10
100 Background: Gastrointestinal obstruction (GIO) is the most common indication for palliative surgical consultation in patients with advanced cancer. The purpose of this study was to delineate the symptom burden and experience of patients with GIO.
METHODS: Twenty patients with advanced cancer and GIO described symptoms at the time of surgical consultation. We used content analysis of interview transcripts and symptoms were ranked by frequency and compared to a general symptom assessment survey (MD Anderson Symptom Inventory).
RESULTS: Malignancy type included colorectal (N = 9), gastric (N = 4), urothelial/renal (N = 3), and other (N = 4), while site of obstruction was small bowel in 11 (55%), gastric outlet in 3 (15%), and large bowel in 6 (30%). Thirteen patients (65%) had received chemotherapy within 6 weeks. Imaging evidence of a primary/recurrent tumor, carcinomatosis, or ascites was documented in 13 (65%), 11 (55%), and 16 (80%) patients, respectively. Thirty symptoms were identified on qualitative interviewing. MD Anderson Symptom Inventory symptoms of pain, nausea, and vomiting were frequently noted. Frequently mentioned GIO-specific symptoms included bloating, cramping, not having a bowel movement, and inability to eat.
CONCLUSIONS: Qualitative research methodology can identify symptoms of importance to patients which can be used to assess improvement after treatment of GIO. Expert panel rating will be used to develop the final symptom item list prior to psychometric testing of the survey.
