Contraception after cancer treatment: describing methods, counseling, and unintended pregnancy risk.

Molly Quinn; J. Letourneau; M.P. Rosen

OBJECTIVE The objective was to describe contraceptive methods utilized by young female cancer survivors and determine whether pretreatment fertility counseling decreases unintended pregnancy risk. METHODS One thousand and forty-one nongynecologic cancer survivors between 18 and 40 years of age responded to a survey of reproductive health, contraceptive methods utilized and history of fertility counseling before cancer treatment. Subjects who had resumed menstrual bleeding following treatment and had not undergone surgical sterilization were defined at risk of unintended pregnancy if they reported unprotected vaginal intercourse in the prior month but did not desire conception. Statistical methods utilized were Students t test and χ(2). RESULTS Overall, 918 women (88%) received treatment with potential to affect fertility (chemotherapy, radiation or sterilizing surgery). Of 476 women younger than 40 years old who still had menses, 58% did not want to conceive; of these 275 women, 21% reported unprotected intercourse in the prior month and were defined at risk of unintended pregnancy. This compares to the 7.3% risk of unintended pregnancy reported by the National Center for Health Statistics. Increasing age was associated with greater risk of unintended pregnancy (odds ratio 1.07, p=.006). The following contraceptive methods were reported: barrier (25.5%), hormonal (24.5%), tubal ligation (21.3%) vasectomy (17.5%), intrauterine device (7.2%) and other (4.0%). Sixty-seven percent of women received pretreatment fertility counseling. Counseling prior to treatment did not decrease risk of unintended pregnancy (p=.93). CONCLUSIONS Sexually active cancer survivors are at threefold increased risk of unintended pregnancy compared to the US population. Contraceptive counseling in this high-risk population is recommended posttreatment. IMPLICATIONS Sexually active cancer survivors are at considerable risk of unintended pregnancy. Patient report of pretreatment counseling regarding fertility was not associated with a decline in risk of unintended pregnancy, highlighting the importance of clear recommendations regarding content and timing of counseling.

STUDY QUESTION Does a breast cancer diagnosis impact ovarian function in the setting of fertility preservation? SUMMARY ANSWER Ovarian reserve and ovarian stimulation outcomes are similar in patients with a new diagnosis of breast cancer and patients undergoing elective fertility preservation. WHAT IS KNOWN ALREADY Prior studies, with small study populations, lack of controlling for individual differences in ovarian reserve and infertile controls, have reported conflicting outcomes for cancer patients undergoing ovarian stimulation for fertility preservation. STUDY DESIGN, SIZE, DURATION This retrospective cohort analysis included 589 patients undergoing ovarian stimulation for fertility preservation between 2009 and 2015. PARTICIPANTS/MATERIALS, SETTING, METHODS Women with a recent breast cancer diagnosis (n = 191) and women desiring elective fertility preservation (n = 398) underwent ovarian stimulation with an antagonist protocol at an academic medical center. The aromatase inhibitor letrozole was administered to breast cancer patients with estrogen-sensitive disease. MAIN RESULTS AND THE ROLE OF CHANCE Baseline antral follicle count (AFC) was not different between the breast cancer patients and controls (15.4 ± 10.4 [mean ± SD] vs 15.4 ± 10.0, P = NS), even after categorization by age. Total (19.4 ± 0.9 [mean ± SEM] vs 17.0 ± 0.5, P = NS) and mature (MII) oocytes retrieved (13.7 ± 0.7 vs 13.2 ± 0.4, P = NS), adjusted for age, BMI and total gonadotropin dose, were also similar between the two groups. Letrozole use was associated with a decreased maturity rate (MII/total oocytes retrieved) compared to elective cryopreservation (0.71 ± 0.01 vs 0.77 ± 0.01, P < 0.001), although the mature oocyte yield [MII/AFC] was comparable (1.01 ± 0.06 vs 0.93 ± 0.03, P = NS). LIMITATIONS, REASONS FOR CAUTION The single center design may impact generalizability. Additionally, the lack of subsequent embryo and pregnancy data is an inherent weakness. WIDER IMPLICATIONS OF THE FINDINGS In females, a breast cancer diagnosis does not impact gonadal function as measured by AFC or ovarian stimulation outcomes. Breast cancer patients should be counseled that their response to ovarian stimulation for fertility preservation is similar to that of patients undergoing elective oocyte cryopreservation.

Background: Little is known about how to predict post-treatment reproductive health outcomes in reproductive-age women with cancer. We sought to determine whether predictors like age, parity, temporary post-treatment amenorrhea, or posttreatment infertility are associated with reproductive compromise. Methods: We contacted 2532 women from a statewide cancer registry (randomly sampled; diagnosed from 1993-2007; ages 18-40 at diagnosis) with a history of chemotherapy treatment for leukemia, lymphoma, breast and gastrointestinal GI) cancers. Using a written and electronic survey, we evaluated outcomes including temporary amenorrhea, permanent amenorrhea, infertility, and early menopause (age < 45). Logistic regression was used to determine the probability of amenorrhea and infertility, based on clinical predictors. Censored data methods were used to determine the probability of early menopause. Results: Out of 1041 responders, 620 women who received chemotherapy alone were included in the analysis of reproductive compromise. One-third noted menses had ceased during or immediately after treatment and one-half of these women noted a subsequent return of menstruation. Temporary amenorrhea post-treatment - but not duration of amenorrhea - predicted a trend toward increased rates of infertility (adjusted odds ratio (AOR) 2.2, 95% CI 1.0-4.8). Post-treatment infertility was significantly associated with an increased risk for earlier menopause (p<0.05 compared to those who did conceive). Conclusions: In this population, clinical metrics including a history of post-treatment amenorrhea and/or infertility appeared to predict risk of future reproductive impairment. These parameters could be used to develop guidelines for triage to reproductive health specialists in women with curable malignancies for whom chemotherapy is recommended.

Accelerating Ovarian Age: Cancer Treatment in the Premenopausal Woman

J. Letourneau; S.-W. Chan; M.P. Rosen

The reproductive sequelae of cancer treatments may provide an important model of accelerated ovarian aging. Tens of thousands of women treated for cancer each year experience infertility and early menopause as a result of treatment. A spectrum of reproductive compromise commonly ranges from immediate menopause at the time of cancer treatment to the less proximate outcome of early menopause in the years to decades after treatment. A womans reproductive lifespan can be shortened after chemotherapy or radiation because such treatments likely decrease the number of viable eggs after treatment. This acceleration in the decline of the number of follicles leads to increased rates of not only infertility and miscarriage but also early menopause, which represents the most extreme form of accelerated ovarian aging. The degree of reproductive impairment is dependent on chronologic age and the diagnosis or treatment. The variation in outcomes that persist may be partially explained by pretreatment ovarian reserve. Establishing the use of clinical predictors such as ovarian reserve markers to effectively anticipate such outcomes is an obvious and important keystone in the foundation of cancer survivorship research. An improved understanding of cancer treatments ability to accelerate follicle death, decrease fecundability, and initiate an earlier menopause could provide a clinically relevant, time-shortened, and reproducible snapshot into the basic biology of ovarian aging.

OBJECTIVE To determine if sexual satisfaction and sexual quality of life (QOL) are different in survivors of localized cervical and ovarian cancers who undergo fertility-sparing surgery (FSS) as compared with standard surgery. METHODS 470 survivors of localized cervical and ovarian cancers diagnosed between the ages of 18-40 were recruited from the California Cancer Registry to complete a cross-sectional survey. Validated questionnaires were used to assess sexual satisfaction and sexual QOL. RESULTS 228 women with localized cervical cancer and 125 with localized ovarian cancer completed the survey. In the cervical cancer group, 92 underwent FSS. Compared with the 84 women who did not undergo FSS (had a hysterectomy, but retained at least one ovary), there was no significant difference in sexual satisfaction or sexual QOL mean scores in women who maintained their uterus (cold-knife cone or trachelectomy), after controlling for age and menopausal status. 82 women with ovarian cancer underwent FSS. Compared with the 39 women that had a bilateral salpingo-oophorectomy, we found no significant differences in sexual satisfaction or sexual QOL in women who maintained at least one ovary (USO or cystectomy), after controlling for age and menopausal status. CONCLUSIONS While FSS may allow for post-treatment fertility, it may not confer a significant benefit with regard to sexual satisfaction or sexual QOL. Thus, the decision to perform FSS should not be dictated based on preservation of sexual functioning.

The role of in-depth reproductive health counseling in addressing reproductive health concerns in female survivors of nongynecologic cancers

M. Shah; J. Letourneau; E.E. Niemasik; M. Bleil; Charles E. McCulloch; M.P. Rosen

ABSTRACT The purpose of this study was to characterize reproductive concerns among female cancer survivors and determine the role of targeted counseling in improving overall reproductive quality of life (QOL). A survey was administered to women from the California Cancer Registry, ages 18-40, with nongynecologic cancers diagnosed from 1993 to 2007, who received fertility-compromising treatments. In total, 356 women completed the survey, which included questions regarding their reproductive health counseling history and the reproductive concerns scale (RCS), a validated reproductive QOL tool. Factors independently associated with higher RCS scores included a desire for children at the time of diagnosis, posttreatment infertility, treatment with chemoradiation or bone marrow transplant, and income less than
