[Development of criteria for assessing the individual risk of breast cancer].

The results of clinico-epidemiological examination of breast cancer patients and controls were used in prognostic tables designed for evaluation of individual risk for breast cancer on the basis of a case history. Practical experience with the said tables showed the percentage of breast tumors detected in patients at high risk selected with the aid of the tables to be several times that of routine mass screenings.

[Importance of anthropometric parameters in breast cancer].

The study of 14 anthropometric findings and indices in a group of primary breast cancer patients with an operable stage of the disease and in the appropriate controls enabled revealing certain differences in the distribution of patients and healthy females with relation to levels of separate anthropometric tests. Some anthropometric findings and their definite numerical values were singled out with respect to which these differences were statistically reliable. The degree of a relatively higher risk of the disease was ascertained in corresponding values of separate indices. Of greatest importance for the increased relative risk of breast cancer were such anthropometric features as obesity (in the extreme age subgroups), asthenia and gynecomastia. With regard to these features the most valuable tests were as follows: Broca's formula, Brugsch index, chest circumference and the ratio of chest circumference to thigh circumference.

[Method of medical history taking and control group recruitment in oncoepidemiological studies].

Some methodical aspects of using the questionnaire as one of the basic tests, employed in oncoepidemiological investigations, are analysed. Under discussion is the potentialities and limits of the questionnairing method; the rules and ways of the optimum application of the given test to obtain the most comprehensive and objective enough information are reported. Also, the principles and criteria of selecting control groups in oncoepidemiological investigations are considered. The factors and conditions which may cause significant differences between the control and "test" groups irrespective of the genesis of the affection under study are discussed. An analysis is made of a number of typical methodical errors in oncoepidemiological investigations.
