BACKGROUND: The aim of this study was to analyze the outcomes of oncologic patients with associated aneurysm of the abdominal aorta (AAA), treated at a specialized cancer (Ca) hospital more than a 10-year period. METHODS: This was a retrospective study, and the data were obtained from our institution's prospective database. Between September 2003 and 2013, a total of 36 consecutive patients with AAA in association with Ca underwent surgical repair. Of these, 9 patients were excluded because the Ca treatment was performed at another service. Most of the patients were male (22) and the most frequent form of neoplasia was prostate Ca. Surgery for AAA repair was performed after the Ca treatment in 19 cases, before Ca treatment in 7 cases and concomitantly in 1 case. The intraoperative characteristics, treatment technique used, complications, patients' clinical evolution, and survival outcomes were analyzed. RESULTS: Endovascular aneurysm repair (EVAR) was used in 19 cases (70.4%) and conventional open repair (OR) in 8 cases (29.6%). Surgical treatment was uneventful in 19 cases, however, when present, postoperative complications occurred more frequently with EVAR (36.84% vs. 12.5%). There were no cases of death related to the aneurysm surgery. Most of the patients in both groups were alive at the end of the study. The probability of survival in our study was 65.8% at 3 years and 53% at 5 years, with no statistically significant difference between the EVAR and OR groups. The main cause of death was progression of the neoplastic disease. CONCLUSIONS: Patients who present Ca in association with AAA benefit from surgical treatment of both conditions, simultaneously or not. In these cases, it is important for the treatment to be individualized, and the disease of greater severity should be treated first. The endovascular and conventional open techniques were shown to be equivalent.
