Potential contribution of therapy to cancer mortality reduction.
Reductions in cancer mortality may come about for a number of reasons, including improvements in treatment. The impact will vary from cancer to cancer. For some, expert curative surgery is crucial, whereas for others, the use of appropriate chemotherapy is a key factor. Examples of the latter, in which there are already discernible reductions in national cancer mortality data resulting from chemotherapy, include testicular cancer and Hodgkin's disease. For more common diseases, such as ovarian cancer, reductions also are being seen. For others, such as breast and colorectal cancer, the current more widespread use of adjuvant chemotherapy may lead to overall mortality reduction in the future. It should be recognized that chemotherapy should be given only by those experienced in its use, and that this facility should form part of a larger provision for health care in relation to cancer, ranging from public education to population screening and from better oncology training for clinicians to greater encouragement to participation in clinical trials. New drug development is clearly a priority, but further advances can be made in many countries already using available forms of chemotherapy if treatment facilities are organized appropriately.
