Neoadjuvant Radiotherapy Followed by Transanal Endoscopic Microsurgery for T1-T2 Extraperitoneal Rectal Cancer (NERATEM)
Objective: Recent randomized and non-randomized studies suggest that neoadjuvant radiotherapy followed by Transanal Endoscopic Microsurgery (TEM) show comparative results to abdominal resection in pT2 extraperitoneal cancer. As the risk of lymphnode metastases is significant already for T1 invasive cancers with submucosa infiltration >1 mm it is our intention to investigate in both T1sm2-3 and T2 rectal adenocarcinomas the effectiveness of this combined treatment in a case series comparing results of this pilot study to an historical series of patients affected by T1-T2 rectal cancer who underwent anterior resection (AR) or total mesorectal excision (TME) with or without abdomino-perineal resection (APR) with no neoadjuvant therapy.
If equally effective, TEM offers a further reduction in invasiveness of treatment, which should correspond to a lower morbidity, mortality and a better quality of life.
