Common Complaints and Causes
In Dr. Dizon’s experience, local symptoms including vaginal dryness, pain with penetration, and vaginal thinning, are common sexual complaints in women with cancer, as are systemic issues such as lack of interest and menopause-type symptoms.
“For those undergoing radiation, the vaginal tunnel can actually develop adhesions, and if not treated proactively this can lead to vaginal stenosis,” said Dr. Dizon, who was not involved in the studies presented at the meeting.

Comorbidities such as diabetes, cardiovascular disease, and musculoskeletal conditions can contribute to sexual issues in women with cancer, according to Nora Lersch, DNP, FNP-BC, AOCNP, and Nicole Dreibelbis, CRNP, the authors of other research presented at the meeting.
Culture, religion, fitness level, history of sexual violence, and gender spectrum health also play a role, as do anxiety and depression, dementia, and substance abuse disorders, the authors wrote in their presentation, “Prioritizing Sexual Health in Gynecological Oncology Care.”
Low libido is a frequent complaint across all cancer types, Ms. Dreibelbis, a nurse practitioner specializing in gynecologic oncology at the UPMC Hillman Cancer Center, Pittsburgh, Pennsylvania, said in an interview.

“Breast cancer patients, especially those on [aromatase inhibitor] therapy, often experience vaginal dryness and therefore dyspareunia,” she added.
The pelvic floor muscles, with their important role in sexual response, can be weakened by cancer treatment or surgery, and the pudendal nerves, which are the primary nerves responsible for sexual response in women, can be affected as well, Dr. Lersch and Ms. Dreibelbis wrote.
Taking Sex Seriously
Researchers are exploring the impact of different cancer prevention treatments for women to mitigate sexual side effects, as illustrated by another study presented at the meeting.
Dr. Barbara Norquist
Dr. Barbara Norquist, MD, a gynecologic oncologist at the University of Washington, Seattle, and colleagues compared the sexual function and menopausal symptoms of patients at high risk of ovarian carcinoma who underwent either interval salpingectomy/delayed oophorectomy (ISDO) or risk-reducing salpingo-oophorectomy (RRSO).
“For patients at high risk for ovarian cancer, surgical removal of the tubes and ovaries is the mainstay of prevention, as screening is not effective at reducing death from ovarian cancer. As a result of surgery, many patients become suddenly postmenopausal from losing their ovaries,” Dr. Norquist said in an interview.
Some patients delay surgery out of concern for health and quality of life, including sexual function, she said.
In the study (known as the WISP trial) the researchers compared data from 166 patients who underwent immediate removal of the fallopian tubes and ovaries and 171 who underwent fallopian tube removal and delayed oophorectomy. All patients completed questionnaires about sexual function. The primary outcome was change in sexual function based on the sexual function index (FSFI) from baseline to 6 months after surgery.
Overall, changes in sexual function were significantly greater in the immediate oophorectomy group, compared with the delayed oophorectomy group at 6 months (33% vs 17%) and also at 12 months (43% vs 20%).
A further review of patients using hormone therapy showed that those in the immediate oophorectomy group still had greater decreases in sexual function, compared with the delayed group, though the difference between groups of patients using hormone therapy was less dramatic.
“I was surprised that, even with hormone replacement therapy, patients undergoing removal of the ovaries still had significant detrimental changes to sexual function when compared to those having the tubes removed, although this was even worse in those who could not take HRT,” Dr. Norquist said, in an interview. “I was reassured that menopausal symptoms in general were well managed with HRT, as these patients did not score differently on menopause symptoms, compared with those having their tubes removed,” she said.
Patients deserve accurate information about predicted changes in menopausal symptoms and sexual function as a result of ovary removal, and HRT should be provided when there is no contraindication, Dr. Norquist told this news organization.
Dr. Norquist and colleagues are awaiting the results of clinical trials investigating the safety of salpingectomy with delayed oophorectomy in terms of ovarian cancer prevention, but more research is needed to identify optimal management of the menopausal and sexual side effects associated with surgical menopause, she noted.
“Findings from the WISP study show the importance of hormones in women undergoing prophylactic surgery,” Dr. Dizon said. The findings indicate that salpingectomy has less of a negative influence on sexual function compared to removal of the ovaries, and the impact of hormone therapy and the relatively young age of the patients who took hormones reinforces current knowledge about hormones and sex, he added.
