Optimal treatment of premature ovarian failure after treatment for Hodgkin's lymphoma is often withheld

Chemotherapy alone vs. chemotherapy plus radiotherapy in female adolescent and young adults with Hodgkin's lymphoma: reproductive health outcomes

PURPOSE

To examine the effects of Hodgkin's lymphoma and its treatment on reproductive health in female adolescent and young adults (AYA).

METHODS

We conducted a retrospective, population-based, matched-cohort study of female patients with Hodgkin's lymphoma diagnosed at 15-39 years of age from 1995 to 2014 in Ontario, Canada. Three female individuals with no history of cancer (unexposed) were matched by birth year and census subdivision to each patient with cancer (exposed). In a subset of the cohort (2005 onwards), the Hodgkin's lymphoma patients were further classified into two groups for analysis based on treatment exposure: (1) chemotherapy alone or (2) combined chemotherapy and radiation. Reproductive health outcomes were infertility, childbirth, and premature ovarian insufficiency (POI). Relative risks (RR) were calculated using modified Poisson regression adjusted for income quintile, immigration status, and parity.

RESULTS

A total of 1443 exposed and 4329 unexposed individuals formed our cohort. Hodgkin's lymphoma patients were at an increased risk of infertility (aRR 1.86; 95% CI 1.57 to 2.20) and POI (aRR 2.81; 95% CI 2.16 to 3.65). While the risk of infertility persisted in both treatment groups (chemotherapy alone, combined chemotherapy plus radiotherapy), the increased risk of POI was only statistically significant in the chemotherapy plus radiotherapy group. No differences in childbirth rates were observed, overall or by treatment exposure compared with unexposed individuals.

CONCLUSIONS

Female AYA survivors of Hodgkin's lymphoma face an increased risk of infertility, independent of exposure to chemotherapy alone, or chemotherapy plus radiotherapy. The risk of POI is higher in those requiring radiotherapy vs. chemotherapy alone.

IMPLICATIONS FOR CANCER SURVIVORS

These results emphasize the importance of pre-treatment fertility counseling and reproductive health surveillance for AYAs diagnosed with Hodgkin's lymphoma.

Menopausal hormone therapy in cancer survivors: A narrative review of the literature

Decision making regarding the use of menopausal hormone therapy (MHT) for the treatment of bothersome menopausal symptoms in a cancer survivor can be complex, and includes assessment of its impact on disease-free or overall survival. Estrogen receptors are present in several cancer types, but this does not always result in estrogen-mediated tumor proliferation and adverse cancer-related outcomes. Estrogen may even be protective against certain cancers. Menopausal hormone therapy is associated with an increased risk of recurrence and mortality after diagnosis of some cancer types, but not others. We provide a narrative review of the medical literature regarding the risk of cancer recurrence and associated mortality with initiation of MHT after the diagnosis of breast, gynecologic, lung, colorectal, hematologic cancers, and melanoma. Menopausal hormone therapy may be considered for management of bothersome menopausal symptoms in women with some cancer types (e.g., colorectal and hematologic cancer, localized melanoma, and most cervical, vulvar and vaginal cancers), while nonhormonal treatment options may be preferred for others (e.g., breast cancer). In women with other cancer types, recommendations are less straightforward, and the use of MHT must be individualized.

Ovarian failure following cancer treatment: current management and quality of life

BACKGROUND

There is a lack of evidence regarding current screening practices for incipient ovarian failure in young women following gonadotoxic therapy and the most appropriate form of estrogen replacement. This study examined the (i) prevalence and management of ovarian failure and (ii) quality-of-life implications of early menopause (EM).

METHODS

A medical case note audit for 288 women with a history of gonadotoxic therapy (aged 18-50 years) was conducted. Self-reported quality-of-life data were obtained from 178 (62%).

RESULTS

Ovarian screening was recorded in 44% of medical case notes, and ovarian failure was documented for 35%. From the self-reported data, 89/178 (50%) women reported experiencing an EM/ovarian failure. Worse menopausal symptoms were negatively associated with both sexual activity [pleasure (r = 0.29, P < 0.01), discomfort (r = 0.50, P < 0.001) and habit (r = 0.22, P < 0.05)] and general quality of life (P = 0.01). Hormone replacement therapy is the most commonly prescribed estrogen preparation; however, 34% of women with EM/ovarian failure reported not taking any replacement therapy.

CONCLUSIONS

Given the extent and impact of menopausal symptoms, further work is needed to establish systems for screening ovarian function and to determine appropriate and effective management of ovarian failure.
