Prevalence of radiotherapy, chemotherapy and access to supportive care in cancer in Brazil, China, France, Russia and the USA.

The objective of this study is to assess the prevalence of treatment with radiotherapy and/or chemotherapy in the general adult population of five countries (Brazil, China, France, Russia and the USA) and to evaluate the use of different Supportive Care in Cancer (SCC) services. A total of 11,100 individuals representing the general population over 18 years of age were recruited from the five countries via a rigorous quota sampling method. There are between 4.1% and 8.78% of respondents reported having undergone medical cancer treatment. Among these subpopulations, the use of at least one SCC was reported by 63% to 86% of respondents. The most commonly used SCC was psychological counselling in France, dietary counselling in Brazil and China, participating in a focus group in the USA and using alternative medicine in Russia. Alternative medicines were chosen by 50% to 61% of patients in every country. This study provides information on the prevalence of patients treated by chemotherapy and/or radiotherapy in representative populations from five countries. Among them, SCC was widely used. However, these uses varied both in proportion and choice, given the cultural differences in patients' and families' health beliefs and values, differences among organisations, in available resources and in ethics and policies among countries.
