[The immune response during combined treatment of breast cancer].

Immunological investigation was carried out in 55 breast cancer patients aged 36 to 62. Multimodality therapy included interstitial gamma-beam therapy with 60Co of the parasternal lymph nodes on the affected side, the isoeffective dose being up to 50 Gy. The major immunological indices during therapy were decreased, and 3 mos. after therapy discontinuation they partially returned to normal.
