BackgroundUp to 6% of women with colorectal cancer are diagnosed in the reproductive age and are at risk for premature ovarian failure
and infertility due to pelvic irradiation and chemotherapy.
Study DesignBetween 1997 and 2007, six women with rectal carcinoma were referred to the McGill Reproductive Center (Montreal, Canada)
for fertility preservation. Following resection of their primary tumor, they were scheduled to undergo pelvic irradiation.
ResultsFive patients underwent laparoscopic ovarian lateral transposition before radiotherapy in order to relocate their ovaries
outside the radiation field. A concomitant ovarian wedge resection was performed for ovarian cryopreservation. In two of these
women, before dissecting the ovarian cortical tissue for cryopreservation, all visible follicles were aspirated. The sixth
patient who had had low anterior resection underwent hormonal ovarian stimulation followed by oocyte retrieval and embryo
ConclusionsFertility preservation in women with rectal cancer is feasible. This includes laparoscopic ovarian transposition and cryopreservation
of ovarian tissue, embryo, or oocyte.
[Show abstract][Hide abstract] ABSTRACT: As the number of cancer survivors continues to increase, oncologists are faced with the challenge of providing cancer therapy to patients who may 1 day want to have children. Yet, gonadotoxic cancer treatments can compromise future fertility, either temporarily or permanently. There are established means of preserving fertility before cancer treatment; specifically, sperm cryopreservation for men and in vitro fertilization and embryo cryopreservation for women. Several innovative techniques are being actively investigated, including oocyte and ovarian follicle cryopreservation, ovarian tissue transplantation, and in vitro follicle maturation, which may expand the number of fertility preservation choices for young cancer patients. Fertility preservation may also require some modification of cancer therapy; thus, patients' wishes regarding future fertility and available fertility preservation alternatives should be discussed before initiation of therapy. This commentary provides an overview of the range of fertility preservation options currently available and under development, using case-based discussions to illustrate ways in which fertility preservation can be incorporated into oncology care. Cases involving breast cancer, testicular cancer, and rectal cancer are described to illustrate fertility issues experienced by male and female patients, as well as to provide examples of strategies for modifying surgical, medical, and radiation therapy to spare fertility. Current guidelines in oncology and reproductive medicine are also reviewed to underscore the importance of communicating fertility preservation options to young patients with cancer.
