Editorial

Peritoneal metastases (PM) are determined in 10% of patients to have colorectal disease (CRC). The finding can be made during follow-up, after resection of the essential growth (metachronous metastases) (4.2% of patients) or simultaneously as the essential cancer (coordinated metastases) (4.8% of patients). The peritoneum is the sole focal point of metastases in 2-5% of CRCs, despite the fact that PM is available in 30% of instances of scattered colon disease and in 5% of patients with spread rectal malignant growth.

Generally, the presence of PM in a patient with CRC has been viewed as a terminal, serious circumstance, helpless just to indicative treatment or palliative chemotherapy. 10 years prior, the middle endurance that could be anticipated in these patients was a year when fundamental chemotherapy was controlled and a half year without it. Lately, there has been a significant improvement in the guess of patients with metastatic CRC following the presentation of current chemotherapy programs in view of 5-fluorouracil + cisplatin/irinotecan. However, the endurance of patients with PM remains lower than that of patients with metastatic spread, without peritoneal contribution.

As of late, cytoreductive medical procedure joined with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) has become far and wide for the therapy of patients with PM. A 5-year endurance of over 40% has been accomplished. In any case, this is a complicated methodology, with high horribleness (16-64%) and mortality (8%), and suitable patient determination for PM stays indistinct.

The distinguishing proof of prescient variables, which are related with reaction to chemotherapy, and prognostic elements, which are related with OS, is fundamental for choosing and arranging the therapy of disease patients. This has been widely considered in patients with CRC metastatic to the liver or lung. Be that as it may, shockingly couple of studies have researched prognostic variables in patients with PM.

Changes of the KRAS oncogene have been viewed as in 30-40% of patients with colorectal liver metastases and have been related with repeat and helpless in general endurance. They are currently perceived as a significant prognostic variable in this sort of patients. We guessed that KRAS changes, as an immediate estimation of growth science, might be a strong indicator of result additionally in patients with CRC with PM treated with perioperative current chemotherapy.

Patients determined to have CRC with PM between January 2006 and December 2019 were incorporated. The patients were chosen from the information gathered in the automated record of the Coloproctology Unit, which was filled in tentatively during these years. The review was endorsed by the Ethics Committee of the Príncipe de Asturias Teaching Hospital. The primary target of the review was to decide the impact of the presence of a change in the KRAS quality on the endurance of CRC patients with PM.

Consideration rules were as per the following: age somewhere in the range of 18 and 75 years, essential cancer with histopathology of adenocarcinoma, and presence of PM recognized during a medical procedure or by radiological methods (MRI or CT Scan with HIPEC convention (organization of intravenous difference during digestive stage and co-organization of 20 ml waterdissolvable oral differentiation (Gastrografin®) weakened in 200 ml of water). The two instances of simultaneous metastases, incidental with the essential cancer, and instances of metachronous metastases, recognized during followup, were incorporated. Avoidance models were as per the following: ECOG (Eastern Cooperative Oncology Group) practical status more noteworthy than 2, patients perished because of postoperative confusions, age north of 80 years, and coordinated cancer of another organ [1-5].

The conclusion of PM was made by histopathological assessment of biopsies acquired during a medical procedure. In cases that didn't go through a medical procedure, the conclusion depended on CT and MRI discoveries. The degree and level of peritoneal sickness was evaluated, and the PCI (peritoneal malignant growth file) was determined for every quiet. When the finding was made, all patients were assessed by a multidisciplinary board of trustees.
