Survival, Healthcare Utilization, and End-of-life Care Among Older Adults With Malignancy-associated Bowel Obstruction: Comparative Study of Surgery, Venting Gastrostomy, or Medical Management.

ABSTRACT: OBJECTIVE:To compare survival, readmissions, and end-of-life care after palliative procedures compared with medical management for malignancy-associated bowel obstruction (MBO). BACKGROUND:MBO is a late complication of intra-abdominal malignancy for which surgeons are frequently consulted. Decisions about palliative treatments, which include medical management, surgery, or venting gastrostomy tube (VGT), are hampered by the paucity of outcomes data relevant to patients approaching the end of life. METHODS:Retrospective study using 2001 to 2012 Surveillance, Epidemiology, and End Results-Medicare data of patients 65 years or older with stage IV ovarian or pancreatic cancer who were hospitalized for MBO. Multivariate competing-risks regression models were used to compare the following outcomes: survival, readmission for MBO, hospice enrollment, intensive care unit (ICU) care in the last days of life, and location of death in an acute care hospital. RESULTS:Median survival after MBO admission was 76 days (interquartile range 26-319 days). Survival was shorter after VGT [38 days (interquartile range 23-69)] than medical management [72 days (23-312)] or surgery [128 days (42-483)]. As compared to medical management, patients treated with VGT had fewer readmissions [subdistribution hazard ratio 0.41 (0.29-0.58)], increased hospice enrollment [1.65 (1.42-1.91)], and less ICU care [0.69 (0.52-0.93)] and in-hospital death [0.47 (0.36-0.63)]. Surgery was associated with fewer readmissions [0.69 (0.59-0.80)], decreased hospice enrollment [0.84 (0.76-0.92)], and higher likelihood of ICU care [1.38 (1.17-1.64)]. CONCLUSIONS:VGT is associated with fewer readmissions and lower intensity healthcare utilization at the end of life than do medical management or surgery. Given the limited survival, regardless of management, hospitalization with MBO carries prognostic significance and presents a critical opportunity to identify patients' priorities for end-of-life care.

Project description:Care of patients with malignant bowel obstruction caused by peritoneal metastases may present an ethical dilemma for surgeons when nonoperative management fails.To characterize outcomes of palliative surgery for malignant bowel obstruction from peritoneal carcinomatosis to guide decision making about surgery and postoperative interventions for patients with terminal illness.We searched PubMed, EMBASE, Cochrane Library, Web of Knowledge, Cumulative Index to Nursing and Allied Health Literature Plus, and Google Scholar and performed manual searches of selected journals from inception to August 30, 2012, with no filters, limits, or language restrictions. We used database-specific combinations of the terms intestinal obstruction, malignant, surgery or surgical, and palliat*. We included studies reporting outcomes after palliative surgery for malignant bowel obstruction from peritoneal carcinomatosis from any primary malignant neoplasm and excluded case studies, curative surgery, isolated percutaneous procedures, stenting for intraluminal lesions, and studies in which benign and malignant obstructions could not be distinguished. We assessed quality with the Newcastle-Ottawa Scale.We screened 2347 unique articles, selected 108 articles for full-text review, and included 17 studies. Surgery was able to palliate obstructive symptoms for 32% to 100% of patients, enable resumption of a diet for 45% to 75% of patients, and facilitate discharge to home in 34% to 87% of patients. Mortality was high (6%-32%), and serious complications were common (7%-44%). Frequent reobstructions (6%-47%), readmissions (38%-74%), and reoperations (2%-15%) occurred. Survival was limited (median, 26-273 days), and hospitalization for surgery consumed a substantial portion of the patient's remaining life (11%-61%).Although palliative surgery can benefit patients, it comes at the cost of high mortality and substantial hospitalization relative to the patient's remaining survival time. Preoperatively, surgeons should present realistic goals and limitations of surgery. For patients choosing surgery, clarifying preferences for aggressive postoperative interventions preoperatively is critical given the high complication rate and limited survival after surgery for malignant bowel obstruction.

Project description:BackgroundAlthough malignant bowel obstruction (MBO) often is a terminal event, systemic therapies are advocated for select patients to extend survival. This study aimed to evaluate factors associated with receipt of chemotherapy after MBO and to determine whether chemotherapy after MBO is associated with survival.MethodsThis retrospective cohort study investigated patients 65 years of age or older with metastatic gastrointestinal, gynecologic, or genitourinary cancers who were hospitalized with MBO from 2008 to 2012 using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database. Fine and Gray models were used to identify factors associated with receipt of chemotherapy accounting for the competing risk of death. Cox models identified factors associated with overall survival.ResultsOf the 2983 MBO patients, 39% (n = 1169) were treated with chemotherapy after MBO. No differences in receipt of chemotherapy between the surgical and medical patients were found in the univariable analysis (subdistribution hazard ratio [SHR], 0.96; 95% confidence interval [CI], 0.86-1.07; p = 0.47) or multivariable analysis (SHR, 1.12; 95% CI, 1.00-1.26; p = 0.06). Older age, African American race, medical comorbidities, non-colorectal and non-ovarian cancer diagnoses, sepsis, ascites, and intensive care unit stays were inversely associated with receipt of chemotherapy after MBO (p < 0.05). Chemotherapy with surgery was associated with longer survival than surgery (adjusted hazard ratio [aHR], 2.97; 95% CI, 2.65-3.34; p < 0.01) or medical management without chemotherapy (aHR, 4.56; 95% CI, 4.04-5.14; p < 0.01). Subgroup analyses of biologically diverse cancers (colorectal, pancreatic, and ovarian) showed similar results, with greater survival related to chemotherapy (p < 0.05).ConclusionsChemotherapy plays an integral role in maximizing oncologic outcome for select patients with MBO. The data from this study are critical to optimizing multimodality care for these complex patients.
