These two volumes are compiled from the presentations and discussions at the second National Cancer Conference. The conference was divided into general sessions, round table discussions, and panel meetings. The general sessions considered such broad subjects as the role of virus in cancer, radiation in cancer, and clinical cancer chemotherapy. Round-table discussions included the significance of statistical analysis; end-results of treatment of breast cancer; and a review of steroid endocrinology of cancer of breast and genitourinary and genital tract. In the panel meetings there were 14 major areas of discussion involving cancer of various anatomic sites, radio-biology, genetics, cytology, chemotherapy, virology, steroid endocrinology, and the utilization of isotopes. Although the conference was held in 1952, these volumes probably best represent present-day experiences of cancer researchers in the fields discussed. It is a valuable textbook for those interested in oncological research and the treatment of neoplastic disease.
