title: [Primary multiple malignant tumors].
abstract: Since 1946 in the Kalinin Province 430 cases with primary multiple tumors were registered--0.39 per cent to all primary oncological patients. Among these patients there were 285 females (0.42%) and 145 males (0.33%). Synchronous tumors were found in 46 cases, metachronous--in 384. The results of radical treatment for recurrent tumors were no worse than for solitary tumors of the same localization.
