title: Effects of steroid hormone therapy on primarily xenotransplanted human colorectal adenocarcinomas.
abstract: Primary xenotransplantation of six different human colorectal adenocarcinomas onto nude mice yielded a mean tumor take of 85%. Administration of steroid hormones induced tumor remissions in some cases. Neither the stage of the original patient's tumors nor their hormone receptor content seemed to be related to the result of the hormone therapies. It is concluded that some colorectal cancers can be treated as hormone-sensitive tumors.
