Résumé
Colorectal cancer is the third most common cancer in France and by the time of the diagnosis, 15-25% of patients will suffer from synchronous liver metastases. Surgery associated to neoadjuvant treatment can cure these patients, but few studies focus only on rectal cancer. This study was meant to compare the outcomes of patients who underwent a simultaneous resection to those who underwent a staged resection (rectum first or liver first) in the University Hospital of Tours, France. We assessed retrospectively a prospective maintained data base about the clinical, pathological and survival outcomes of patients who underwent a simultaneous or a staged resection in our center between 2010 and 2018. A propensity score matching was used, considering the initial characteristics of our groups. There were 70 patients (55/15 males, female respectively) with median age 60 (54-68) years. After matching 48 (69%) of them underwent a staged approach and 22 (31%) a simultaneous approach were compared. After PSM, there were 22 patients in each group. No differences were found in terms of morbidity (p = 0.210), overall survival (p = 0.517) and disease-free survival (p = 0.691) at 3 years after matching. There were significantly less recurrences in the simultaneous group (50% vs 81.8%, p = 0.026). Simultaneous resection of the rectal primary cancer and synchronous liver metastases is safe and feasible with no difference in terms of survival.

BACKGROUND
BACKGROUND
Colorectal cancer is the third most common cancer in France and by the time of the diagnosis, 15-25% of patients will suffer from synchronous liver metastases. Surgery associated to neoadjuvant treatment can cure these patients, but few studies focus only on rectal cancer. This study was meant to compare the outcomes of patients who underwent a simultaneous resection to those who underwent a staged resection (rectum first or liver first) in the University Hospital of Tours, France.
METHODS
METHODS
We assessed retrospectively a prospective maintained data base about the clinical, pathological and survival outcomes of patients who underwent a simultaneous or a staged resection in our center between 2010 and 2018. A propensity score matching was used, considering the initial characteristics of our groups.
RESULTS
RESULTS
There were 70 patients (55/15 males, female respectively) with median age 60 (54-68) years. After matching 48 (69%) of them underwent a staged approach and 22 (31%) a simultaneous approach were compared. After PSM, there were 22 patients in each group. No differences were found in terms of morbidity (p = 0.210), overall survival (p = 0.517) and disease-free survival (p = 0.691) at 3 years after matching. There were significantly less recurrences in the simultaneous group (50% vs 81.8%, p = 0.026).
CONCLUSIONS
CONCLUSIONS
Simultaneous resection of the rectal primary cancer and synchronous liver metastases is safe and feasible with no difference in terms of survival.
