The choice of local destruction method of colorectal cancer liver metastases

Aim. To analyze the results of a multidisciplinary approach to the treatment of patients with hepatocellular cancer in a multidisciplinary oncology clinic.Materials and Methods. From 2007 to 2021, 259 patients with hepatocellular cancer were surgically treated in the Department of Liver and Pancreas Surgery of the city clinical hospital named after S.P. Botkin. Liver resections of different extent were performed in 74 (28.6%) patients, radiofrequency ablation – in 19 (7.3%), microwave ablation – in 20 (7.7%), hepatic artery chemoembolization with radiofrequency ablation – in 34 (13.1%), regional chemotherapy – in 104 (40.2%), liver transplantation – in 8 (3.1%) patients.Results. The overall five- and ten-year survival after liver resection was 51.4% and 31.1% respectively. The poor prognostic factors following liver resection were age >70 years (p = 0.03), postoperative complications (p = 0.04), lymph node metastases (p = 0.01), and a body mass index >30 kg/m2 (p = 0.045). Complications that developed after radiofrequency (microwave) ablation and chemoembolization of the hepatic artery with radiofrequency ablation were 5.1% and 5.8%. Within 90 days after liver resection, three (1.1%) patients died. Complications after resection developed in 18 (24.3%) cases during the same period. With metastases measuring ≤3 cm, the overall five-year survival after radiofrequency and microwave ablation was 36.8% and 35% respectively. With neoplasms measuring 3–5 cm, the best five-year survival was after hepatic artery chemoembolization and radiofrequency ablation (44.1%). The overall fiveyear survival after hepatic artery chemoembolization was 11.5%. No complications or deaths resulted from liver transplantation. With an average follow-up period of 12.5 months, none of the patients experienced disease recurrence or died.Conclusion. Using a multidisciplinary approach in a multidisciplinary oncology clinic improves the results of treating patients with hepatocellular cancer.

Intraoperative ultrasound (IOUS) is a diagnostic technique that allows obtaining additional information about the number and localization of colorectal cancer (CRC) metastases in the liver (especially with their intraparenchymal location), determining their relationship with the arteries and veins of the liver, navigating for puncture biopsy and / or performing minimally invasive treatment of lesions, and adjusting the amount of resection intervention on the liver during surgery. When performing minimally invasive medical procedures, IOUS application helps to avoid injuries to blood vessels, bile ducts and adjacent organs, and also allows evaluating the effectiveness of treatment and identifying potential complications. An important component of IOUS is the support of surgical procedures with a staged assessment of the liver hemodynamics, providing an immediate correction of the surgical situation. Thus, IOUS is a safe, inexpensive and highly informative diagnostic option, which should be a mandatory diagnostic step in the surgical treatment of CRC liver metastases.Based on literature data and personal experience, the authors present indications, technical aspects and features of application of various IOUS options and modalities in the surgical treatment of CRC liver metastases.

Aim. To analyze multimodal treatment outcomes in patients with liver metastases from colorectal cancer, who were treated at multidisciplinary cancer clinic. Material and methods. From 2007 to 2021, 315 colorectal cancer patients with liver metastases underwent liver resections (201, 63.8 %), radiofrequency ablation (RFA) (29, 9.2 %), microwave ablation (MWA) (22, 6.9 %), transarterial chemoembolozation (TACE) in combination with RFA (22, 6.9 %), and TACE + RFA + TACE combination (41, 13.2 %) at the department of liver and pancreas surgery, Moscow Botkin Clinical Hospital. Results. A 90-day mortality rate was 1.9% in 6 patients who underwent liver resection. Postoperative complications after liver resection were observed in 49 patients (24.3 %). The overall 5- and 10-year survival rates after liver resection were 38.8 % and 23.2 %, respectively. The factors of poor prognosis after liver resection were: age over 70 years (p=0.03), localization of the primary tumor in the right half or rectum (p=0.037), three or more metastatic foci in the liver (p=0.01), maximum size of the tumor of more than 5 cm (p=0.021), synchronous colorectal liver metastases (p=0.039), and bilobar colorectal liver metastases (p=0.007). Postoperative complications after RFA, TACE + RFA, TACE + RFA + TACE WERE 5.8 %, 9.1 % and 7.3 %, respectively. In patients with a size of metastases of no more than 3 cm, the 3-year disease-free and overall survival rates after rfa were 45.8 % and 54.2 %, respectively. In patients with a size of metastases from 3 to 5 cm, the 3-year disease-free and overall survival rates after TACE + RFA + TACE were 56.1 % and 63.4 %, respectively. Conclusion. In colorectal cancer patients with liver metastases, multimodal treatment within a multi-disciplinary setting demonstrated significant improvements in their survival.
