EPIDEMIOLOGY OF BREAST CANCER IN UKRAINE WITH CONSIDERATION OF THE FACTORS OF THE CHORNOBYL ACCIDENT.

Objective: Assessment of the possible impact of the Chornobyl accident on the incidence of breast cancer in the female population of Ukraine as a whole and in some affected groups.

Object Of The Study: The female population of Ukraine as a whole and in separate groups of victims - women par- ticipating in the clean-up works in 1986-1987, evacuaees from the exclusion zone and inhabitants of the territo- ries most contaminated with radionuclides.

Methods: Statistical, mathematical, cartographic.

Quarter of century since the Chornobyl accident: сancer risks in affected groups of population.

Objective. The goal of this study was to define levels and dynamic trends of cancer incidence at whole and some separate sites in groups of Ukrainian population affected by the Chornobyl accident during a long period of observation. Materials and methods.

Age and gender patterns of thyroid cancer incidence in Ukraine depending on thyroid radiation doses from radioactive iodine exposure after the Chornobyl NPP accident.

Unlabelled: The objective of this study was to investigate the thyroid cancer incidence in a whole territory of Ukraine and to clear up its age and gender patterns depending on average regional (oblast) thyroid doses from radioactive iodine due to the Chornobyl accident. MATERIALS AND METHODS. On the basis of average accumulated thyroid doses from radioactive iodine the geographical regions of Ukraine with low and high average thyroid doses were identified for a comparative analysis performance.

Treatment of large osteosarcoma in children: new approach.

Aim: To improve the treatment results of patients with locally advanced osteosarcoma with large volume using neoadjuvant chemotherapy (NACT) (ifosfamide at a dose of 18 g/ml) and planning of organ-conserving surgery by evaluating the state of tumor pseudocapsule.

Patients And Methods: A study group included 46 children aged from 7 to 18 years, mean age - 12 years. In 68% of the patients tumor volume was larger or significantly larger than 200 ml (from 27 to 2400 ml), mean tumor volume was 342 ml.

Cancer incidence and nuclear facilities in Ukraine: a community-based study.

Unlabelled: The study goal was to investigate malignant tumors incidence in 5 Ukrainian cities with nuclear hazardous enterprises: extractive, processing enterprises of uranium ore (Zhovti Wody and Dniprodzerzhynsk of Dnipropetrovsk region) and nuclear power stations (Energodar of Zaporizhska region, Pivdennoukrainsk of Mykolayivska region, Netishyn of Khmelnytska region).

Materials And Methods: average annual population of the cities under study in 2003-2008 was 439 600 persons. Total and specific cancer incidence was investigated.
