CROSCO-1: Colonic Resection or Stoma, or Self-expandable Metallic Stent for obstruCtive Left cOlon Cancer
Study Details
Study Description
Brief Summary
CROSCO-1 study is a national, multi-center, prospective observational study presenting patients to the emergency departments of the participating centers with obstructive left colon cancer (in the absence of metastases and peritoneal carcinomatosis) undergoing primary surgical tumor resection with a primary colorectal anastomosis (associated or not with a diverting loop ileostomy) or without a primary anastomosis ("Hartmann's procedure") or staged resection after endoscopic stenting with Self-expandable Metallic Stent (SEMS).
The main questions it aims to answer are:
-
the Stoma rate at 1 year after tumor resection
-
the 30-day and 90-day major morbidity and mortality
-
1-year quality of life (EQ-5D-5L test)
-
Timing of chemotherapy initiation and type of chemotherapy regimen. Participants will have an obstructive left colon cancer localized (no peritoneal carcinosis or distant metastasis).
Researchers will compare: primary surgical tumor resection with a primary colorectal anastomosis (associated or not with a diverting loop ileostomy) or an "Hartmann's procedure" with a staged resection after endoscopic stenting with SEMS.

Detailed Description
Since surgical and oncological outcomes of the different treatment strategies for obstructing left colon cancers have not been studied on a large scale globally, we launched the CROSCO-1 study intending to compare the clinical results of all these therapeutic regimens in a cohort of patients treated for obstructive left-sided colorectal cancer (CRC).
The primary aim of the CROSCO-1 (Colonic Resection, stOma or self-expanding metal Stents for obstruCtive left cOlon cancer) study is to describe the outcomes of the management of emergency presentations of obstructive left CRC with colorectal resection with or without primary anastomosis versus the staged approach with SEMS insertion and subsequent colorectal resection. The primary aim of the CROSCO-1 study will be the 1-year stoma rate of patients undergoing primary emergency surgical resection (Hartmann procedure or primary resection and anastomosis) compared with patients undergoing staged resection (emergency endoscopic treatment with SEMS followed by elective resection). Other outcomes will be 30-day and 90-day major morbidity and mortality, 1-year quality of life, and the timing and type of chemotherapy initiation in the two groups.

Outcome Measures
Primary Outcome Measures
- Stoma rate at 1 year after tumor resection [1 year]
the number of stomas after 1 year of primary surgery with tumor resection
Secondary Outcome Measures
- 30-day and 90-day major morbidity [30-days; 90-days]
morbidity after 30 and 90-days
- 30-day and 90-day mortality [30-days; 90-days]
mortality (Overall survival) after 30 and 90-days
- 1-year quality of life (The 5-level EQ-5D version (EQ-5D-5L)test) [1-year]
The EQ-5D-5L is an instrument to describe the quality of life with a state system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. In this first part, the patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions with graduate answers from 1 (no problem) to 5 (extreme limitations). The aggregation of the responses forms a five-digit number representing the patient's health status. in the second part, the patient is asked to indicate an assessment using a visual analog (VAS) graphically represented by a graduated scale ranging from 0 (the worst possible state of health) to 100 (the best possible state of health) on which the interviewee indicates his or her perceived level of health.
- Timing of chemotherapy initiation [2-years]
data for chemotherapy initiation in both groups of study
- type of chemotherapy regimen [2-years]
type of drugs regimen in both groups of study
