[New opportunities for proton therapy in Russia].

On November 23, 2015 in Protvino of the Moscow Region there was begun proton therapy using Russia's first medical therapeutic complex "Prometheus" produced by JSC "PRO- TOM" and certified to treat patients with head and neck tumors. The complex allows irradiating patients with active scanning beam. Energy of beam is 30-250MeV and maximum field size is 10 cm vertically and 40 cm horizontally.

[Prognostic value of hemoglobin concentration in the course of chemoradiotherapy of patients with oropharyngeal squamous cell carcinoma].

There was performed a comparative analysis of the indicators of immediate and long-term results of chemoradiotherapy in 342 patients with squamous cell oropharyngeal carcinoma depending on hemoglobin level before and after treatment. In patients with normal level of hemoglobin a rate of response to treatment was almost two times higher than that of patients with anemia (75,3% vs. 23,5%) and complete regression of tumors was detected by more than three times often (65,4% vs.

[An experience with dose-escalated conformal radiation therapy in hormone-radiotherapy for prostate cancer].

This study presents the short-term outcomes of conformal external beam radiation therapy given in conjunction with hormone therapy to 110 patients with prostate cancer. We performed a comparative analysis of the rate and degree of radiation reactions and complications following delivery of a total dose of 70 Gy and 72-76 Gy to the tumor. In prostate cancer, a continuous course of dose-escalated conformal radiation therapy resulted in satisfactory tolerance and acceptable levels of late complications.
