Total pelvic exenteration for locally advanced and locally recurrent rectal cancer in the elderly

摘要

BackgroundTotal pelvic exenteration (TPE) is a radical approach for locally advanced rectal cancer (LARC) and locally recurrent rectal cancer (LRRC) in case of tumour invasion into the urogenitary tract. The aim of this study is to assess surgical and oncological outcomes of TPE for LARC and LRRC in elderly patients compared to younger patients. MethodsAll patients who underwent TPE for LARC and LRRC between January 1990 and March 2017 were retrospectively analyzed. Patients aged ?II patients (p?=?0.01). Indication for surgery LARC (n?=?73) and LRRC (n?=?53) did not differ significantly. The 30-day mortality rate was significantly higher (p?=?0.01) in elderly (13%) compared to younger patients (3%). Elderly patients experienced more anastomotic leakage (p?=?0.02). Median overall survival (OS) was 75 months [95%CI 37.1; 112.9] for elderly and 45 months [95%CI 22.4; 67.8] for younger patients (p?=?0.77). The 5-year OS rate was 44% in both groups. Median disease specific survival (DSS) was 78 months [95%CI 69.1; 86.9] for elderly and 60 months [95%CI 36.6; 83.4] for younger patients (p?=?0.34). The 5-year DSS rate was 57% and 49%, respectively. ConclusionTPE is an invasive treatment for rectal cancer with high 30-day mortality in elderly patients. Oncological outcomes are similar in elderly and younger patients. Therefore, TPE should not be withheld because of high age only, but careful patient selection is needed.
