[Surgical treatment of multiple primary neoplasms]

Comparison of two groups of patients with polyneoplasia was carried out: in group 1 surgeries were performed simultaneously, in group 2--at different time. Choice of surgical technique seems to depend on the time between detection of the tumors. When polyneoplasias were revealed at the same time, surgeries were performed simultaneously. These operations were conducted more often when the tumors were localized in organs accessible by one surgical approach. When multiple synchronous tumors located in various anatomic regions consecutive operations were performed more often. The stage of the tumor does not influence the choice of time of operation for the first and second tumor. Simultaneous operations are preferable for young patients without concomitant diseases.
