Attitudes toward fertility and fertility preservation in women with glioma

Background

No studies have examined the fertility priorities of women undergoing treatment for their glioma. Glioma patients frequently undergo chemotherapy as part of their treatment; however, it is unknown whether patients truly are aware of its possible effects on their fertility. Our objective was to assess the fertility priorities of glioma patients and ascertain whether female glioma patients are being effectively counseled on the effects of chemotherapy on their fertility prior to beginning treatment.

Methods

The sample was composed of female patients from the Neuro-oncology clinic of the University of California, San Francisco. Participants completed a cross-sectional survey between October 2010 and December 2013 exploring their attitudes toward fertility and their experience with fertility counseling prior to chemotherapy initiation.

Results

Seventy-two women completed the survey. Analysis of the survey results showed that 30% of women receiving chemotherapy reported having a discussion regarding fertility preservation prior to beginning treatment. Of those who reported having this discussion, 80% were aware that chemotherapy could negatively affect their fertility. Many women reported that while fertility preservation was not important to them at the time of diagnosis, it was a priority for them at the time of survey completion. Although interest in having children tended to decrease after cancer treatment, the majority of respondents reported wanting a child after treatment.

Conclusions

The data obtained in this study suggest a lack of understanding of reproductive priorities, which may be addressed with a more comprehensive fertility discussion prior to beginning treatment.

Female fertility: is it safe to "freeze?"

Objective:

To evaluate the safety and risk of cryopreservation in female fertility preservation.

Data sources:

The data analyzed in this review were the English articles from 1980 to 2013 from journal databases, primarily PubMed and Google scholar. The criteria used in the literature search show as following: (1) human; embryo; cryopreservation/freezing/vitrification, (2) human; oocyte/immature oocyte; cryopreservation/ freezing/vitrification, (3) human; ovarian tissue transplantation; cryopreservation/freezing/vitrification, (4) human; aneuploidy/DNA damage/epigenetic; cryopreservation/freezing/vitrification, and (5) human; fertility preservation; maternal age.

Study selection:

The risk ratios based on survival rate, maturation rate, fertilization rate, cleavage rate, implantation rate, pregnancy rate, and clinical risk rate were acquired from relevant meta-analysis studies. These studies included randomized controlled trials or studies with one of the primary outcome measures covering cryopreservation of human mature oocytes, embryos, and ovarian tissues within the last 7 years (from 2006 to 2013, since the pregnancy rates of oocyte vitrification were significantly increased due to the improved techniques). The data involving immature oocyte cryopreservation obtained from individual studies was also reviewed by the authors.

Results:

Vitrifications of mature oocytes and embryos obtained better clinical outcomes and did not increase the risks of DNA damage, spindle configuration, embryonic aneuploidy, and genomic imprinting as compared with fresh and slow-freezing procedures, respectively.

Conclusions:

Both embryo and oocyte vitrifications are safe applications in female fertility preservation.

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

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 Student's 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.
