title: [Frequency of thyroid cancer in the presence of nodular formations, its diagnostic, growth and intraorganic distribution characteristics].
abstract: Among different thyroid abnormalities thyroid cancer was seen in 179 (15.8%) of 1127 operated patients. Cancer mainly occurred in patients with nodoseeuthyroid or combined goiter: in 111 (19.3%) of 573 patients. In 69 subjects cancer developed in the unaffected thyroid gland, 20 of them had multifocal lesions; 42 subjects had cancer coupled with hyperplastic process, multifocal tumor being diagnosed in 12 persons. The data obtained indicate high cancer incidence in the unaffected thyroid gland. Cancer-hyperplasia complex must be regarded as a specific pathological variety being the most difficult for diagnosis and treatment.
