Multiple primary synchronous neoplasms of the sigmoid colon and breast in combination with spinal cord meningioma. Clinical case

The incidence of multiple primary oncological diseases ranges from 2.4% to 17%. The main causes of primary multiple diseases include factors related to the patient's lifestyle, environmental and genetic factors, as well as factors related to the comprehensive treatment of previously identified malignant diseases.We demonstrate a clinical case of treatment of a patient with synchronous primary multiple cancer of the sigmoid colon and breast in combination with spinal cord meningioma. An interesting fact is the possible correlation between meningioma and breast cancer. Thus, the risk of meningioma in women who have had breast cancer and the risk of breast cancer in women with a history of meningioma is moderately increased (RR = 1.40-1.64 and 1.54, respectively). This two-way statistical association may be a consequence of common risk factors and a partial coincidence of gene-environmental interactions that determine carcinogenesis. Further research is needed to identify problems of prevention, screening, diagnosis, treatment and disease-free survival. It is important that patients diagnosed with cancer have information about possible late and long-term consequences of treatment and its symptoms, as well as possible signs of relapse and the appearance of secondary tumors. It is important that patients receiving treatment for malignant neoplasms follow the recommendations for cancer prevention and early detection, including smoking cessation, physical activity, nutrition and diet, a healthy weight and all standard cancer screening tests.
