Multiple Primary Neoplasms (Literature Review)
Primary multiple tumors are an independent emergence and development two or more neoplasms in one patient. Thus can be the struck not only different bodies of various systems, but pair bodies (mammary glands, lungs, etc.) also, and one body with multicentric defeat. Primary multiple tumors can be synchronous and metachronous. The increase in frequency of multiple neoplasms is noted in recent years. The factors influencing growth of incidence of malignant primary multiple tumors are: increase in average duration of life as in general, and after successful treatment of oncological diseases; increase of intensity of cancerogenic influences, urbanization, accumulation of a hereditary burdeness, improvement of diagnosis of oncological diseases. Insufficient knowledge of doctors of possibility of multiple tumoral defeat, often, is the reason of that after detection of one malignant tumor possibility of existence of other tumors isn't taken into account and therefore purposeful research of other parts of body in which the tumor, and also other bodies developed in certain cases isn't made. Also, considering the opportunity of development of metachronous tumors, postoperative monitoring of the patient condition has to become an important aspect of tactics of treatment of the patients with this pathology.
