The indications of the liver resection are the primary and secondary malignant neoplasms of the liver, the benign liver tumors and some inflammatory diseases. Approximately 10-30% of the patients with colorectal cancer liver metastases are suitable to a curative liver resection. The aim of the study is to presenti of the operative-technical special features of the anatomical left lobectomy of patients with colorectal cancer liver metastases. In the course of 24 months we carried out 9 anatomical left liver resections. The indications of the operation of eight of them were solitary metastases, which had appeared after an operation on colorectal cancer and at one of them the resection was performed due to an angiosarcoma of the liver. The operative blood loss was in the order of 100 ml. The operative mortality and postoperative morbidity were 0%. The anatomical knowledge of the Rex's recessus is a key of utmost importance for the performance of a left lobectomy. The Rex's recessus is a physiological enlargement of the left branch of v.porta in the region of the clamping of ligamentum teres. The liver resection highly improves the prognosis on the following conditions: a radical treatment of the primary tumor, an absence of local recurrence, an absence of an extrahepatic incidence of the primary tumor and a preservation of a sufficient capacity of the liver.

Colon cancer, as a highly prevalent malignant tumor globally, poses a significant threat to human health. In recent years, ferroptosis and cuproptosis, as two novel forms of cell death, have attracted widespread attention for their potential roles in the development and treatment of colon cancer. However, the investigation into the subtypes and their impact on the survival of colon cancer patients remains understudied.

Hepatobiliary (HB) contrast agents are increasingly valuable diagnostic tools in MRI, offering a wider range of applications as their clinical use expands. Normal hepatocytes take up HB contrast agents, which are subsequently excreted in bile. This property creates a distinct HB phase providing valuable insights into liver function and biliary anatomy.

Background: Cancer patients have up to a 3-fold higher risk for cardiovascular disease (CVD) than the general population. Traditional CVD risk scores may be less accurate for them. We aimed to develop cancer-specific CVD risk scores and compare them with conventional scores in predicting 10-year CVD risk for patients with breast cancer (BC), colorectal cancer (CRC), or lung cancer (LC).

Background Human papillomavirus (HPV)-associated cancers are a global concern, particularly for sexual minority men (SMM). Understanding awareness and the determinants of these beliefs is crucial for developing educational programs to reduce HPV-associated cancers. This study explored awareness and determinants of beliefs about HPV's carcinogenicity among SMM living with and without HIV in Nigeria.

Importance: High-quality colonoscopy reduces the risks of colorectal cancer by increasing the adenoma detection rate. Routine use of an automatic quality control system (AQCS) to assist in colorectal adenoma detection should be considered.
Objective: To evaluate the effect of an AQCS on the adenoma detection rate among colonoscopists who were moderate- and low-level detectors during routine colonoscopy.
