Pathology Assessment of Mesorectal Fascia After TME by Laparoscopic, Open, TransAnal and Robotic Approaches (LOTARTME)

In the researchers' words

TME is the gold standard surgical treatment of rectal cancer. Specimen quality, integrity of mesorectal fascia and lymph nodes harvest are expression of radicality and good surgery. The LOTARTME study is designed to assess which of the open, laparoscopic, robotic and endoscopic transanal approach is superior. Primary outcome is the evaluation of completeness of mesorectal fascia according to Quirke classification. Secondary outcomes are lymph nodes harvest, local recurrences, overall survivals, cancer related survivals. Inclusion criteria: any patient of any age and sex undergoing to intent-to-treat surgery operated by experienced surgeon. Exclusion criteria: patients with rectal cancer undergoing palliative surgery or multivisceral resection; all patients operated by less experienced surgeons. Study period January 1, 2017 - June 30 2021 and patients enrollment: January 1, 2017 - December 31, 2020. Data collection and analysis: data are collected in a prospective database and statical analysis is carried out using AnalystSoft StatPlus for Windows Software.
