[Range of combined treatment of locally advanced skin cancer].

Due to combined use of surgery, chemo- and radiotherapy, 58.8% of patients with locally advanced squamous cell carcinoma survived for 5 years. More organ-saving operations could be performed as a result of administering cisplatin, bleomycin and 5-fluorouracil chemotherapy in conjunction with radiation and subsequent surgery.

[Comparison of methods of reconstructive vascular and microvascular surgery used in management of tumors].

Choice of procedure of treatment of defects of reconstructive surgery for locally advanced tumors is discussed. Part 1 deals with use of autovenous vessels and synthetic prosthetics for management of chief artery defects, while Part 2--with bone, soft tissue and skin defects as well as combination defects. Experience with application of free grafts and flaps in microvascular anastomosis is evaluated and relevant recommendations are given.

[Prognostic significance of p53, HER-2/neu, Ki-67 and VEGF expression in chondrosarcomas].

Expression of the mutant protein-suppressor of tumor growth p53 and the receptor of epidermal growth factor of type II--HER-2/neu may serve as prognostic factors for patients with chondrosarcoma of malignancy grade II. Combined expression of these proteins in the tumor tissue correlates with shorter 5-year survival of recurrence-free patients. The data obtained may be used for prognosis of chondrosarcoma course and choice of adequate therapy.

[Treatment of limb osteosarcoma at the turn of the century (half century of experience in research)].

The Russian Cancer Research Center has experience in diagnosing and treating more than 800 patients with osteosarcoma who have been treated at the Clinic of General Oncology since 1952. Survival rates were no more than 10% before the 1970s when the only treatment was surgical. The use of adjuvant chemotherapy after radical surgery has increased survival up to 45-60%.
