AN APPROACH TO THE DETERMINATION OF A PROGNOSTIC INDEX FOR THE SCOPE OF SIMULTANEOUS RESECTION IN PATIENTS WITH SYNCHRONOUS COLORECTAL LIVER METASTASES.

Based on the results of 62 simultaneous operations in patients with synchronous liver metastases from colorectal cancer, an attempt was made to calculate the index, assisting the surgeon in the selection of the liver resection, considering the sensitivity and specificity of the test. The index is calculated using equations based on variables and their coefficients from Cox regression analysis. The type of surgery is associated with prognosis for survival of the operated patients. The results can serve as a basis for further research in this area.
