The ACO-ASSO (Austrian Society of Surgical Oncology) colorectal group and Austrian Working Group for Coloproctology present the LARS Austria study. It is a prospective, multicenter observational study. The primary objective of this study is to collect information about LARS (LARS score) and QoL (EORTC -CR29) in patients with non-metastatic rectal cancer who received therapy. As a secondary objective, the impact of radiotherapy on the occurrence of LARS will be investigated.
All consecutive patients with biopsy verified rectal cancer (≤16cm from anocutaneous line) can be included in the study. For the study, tumors whose aboral margin, when measured with a rigid rectoscope, is 16 cm or less from the anocutaneous line will be included. Thus, only histologically verified tumors of the lower (<6 cm), middle (6<12 cm) and upper (12-16cm) rectal thirds are included.
Patients will be included after the indication for further therapy has been established in the tumor board according to guideline criteria and after signing the participation consent. The collection of study relevant data will be performed according to the following scheme:
Group 1 = patients without neoadjuvant radiochemotherapy (RCHT). Collection of data and questionnaires before surgery and 3, 6, and 12 months after index surgery (if no protective stoma).
OR Collection of data and questionnaires before surgery and 3, 6, or 12 months after stoma re-operation (if protective stoma).
Group 2 = patients with neoadjuvant RCHT/ definitive RCHT=watch and wait. Collection of data and questionnaires before RCHT and before surgery or after RCHT and 3, 6, or 12 months after index surgery (if no protective stoma).
OR Collection of data and questionnaires before RCHT and before operation=surgery(OP) or after RCHT and 3, 6 or 12 months after stoma closure (if protective stoma) OR Collection of data and questionnaires before RCHT and 3, 6 and 12 months after RCHT (if no surgery)

| Measure | Description | Time Frame |

| Detection of Low Anterior Resection Syndrome (LARS) after anterior rectal resection. | Occurrence of Low Anterior Resection Syndrome (LARS) will be measured with an LARS Score. The score ranges from 0 to 42 is divides into no LARS (0 to 20 points), minor LARS (21 to 29 points), and major LARS (30 to 42 points) | 3 months after the rectum resection or after the closure of a protective ileostomy or after an Chemoradiation in case of watch and wait |
