Severe Menorrhagia Associated With Thrombocytopenia

A systematic approach to the management of menses prophylaxis and suppression in pre-menopausal hematologic cancer patients

OBJECTIVE

Hematologic malignancies in women of reproductive age carry significant additional morbidity due to menstrual bleeding in conjunction with disease and treatment-associated cytopenias. Several agents for menses prophylaxis and suppression exist, but there is a paucity of data comparing these therapies, particularly in the cancer setting.

DATA SOURCES

A thorough literature review and evaluation of available data was conducted via PubMed search and combined with clinical expertise.

DATA SUMMARY

The goal of prophylaxis therapy is to induce amenorrhea until it is considered safe to resume menstrual cycles. GnRH agonists remain the management of choice in achieving menses control and amenorrhea. Suppression is more likely achieved when the therapy is initiated in the late luteal phase or with the concomitant use of oral contraceptives. The effective use of oral contraceptives is achievable in appropriately selected patients. Although attractive as prophylactic agents, GnRH agonists have a slow onset of amenorrhea and can be associated with an initial increase in bleeding, thus are of limited value in immediate menorrhagia management. We recommend prioritizing estrogen therapy given its documented efficacy, and adding tranexamic acid as a secondary agent for severe or refractory bleeding.

CONCLUSIONS

Thus far in the literature, this is the most comprehensive proposed pathway for the prevention and suppression of menorrhagia in hematologic cancer patients. Our protocol provides a step-wise approach for the management of menses prophylaxis and suppression to provide standardization amongst clinicians and adaptations for patient-specific needs.

Hormone Use for Therapeutic Amenorrhea and Contraception During Hematopoietic Cell Transplantation

There is a growing population of women who have or will undergo hematopoietic stem cell transplant for a variety of malignant and benign conditions. Gynecologists play an important role in addressing the gynecologic and reproductive health concerns for these women throughout the transplant process. As women undergo cell transplantation, they should avoid becoming pregnant and are at risk of uterine bleeding. Thus, counseling about and implementing hormonal treatments such as gonadotropin-releasing hormone agonists, combined hormonal contraceptives, and progestin-only methods help to achieve therapeutic amenorrhea and can serve as contraception during the peritransplant period. In this commentary, we summarize the timing, risks, and benefits of the hormonal options just before, during, and for the year after hematopoietic stem cell transplantation.

Management of menorrhagia associated with chemotherapy-induced thrombocytopenia in women with hematologic malignancy

Abnormal uterine bleeding in women with a blood dyscrasia, such as leukemia, or who experience thrombocytopenia secondary to myelosuppressive chemotherapy is a clinical condition associated with significant morbidity. Consequently, effective management is necessary to prevent adverse outcomes. Prevention of menorrhagia, defined as heavy regular menstrual cycles with more than 80 ml of blood loss/cycle or a cycle duration longer than 7 days, in this patient population is the goal of therapy. Gonadotropin-releasing hormone analogs (e.g., leuprolide) are promising therapies that have been shown to decrease vaginal bleeding during periods of thrombocytopenia and to have minimal adverse effects other than those associated with gonadal inhibition. In patients who experience menorrhagia despite preventive therapies, or in patients who have thrombocytopenia and menorrhagia at diagnosis, treatment is indicated. For these women, treatment options may include platelet transfusions, antifibrinolytic therapy (e.g., tranexamic acid), continuous high-dose oral contraceptives, cyclic progestins, or other therapies for more refractory patients such as danazol, desmopressin, and recombinant factor VIIa. Hormonal therapies are often the mainstay of therapy in women with menorrhagia secondary to thrombocytopenia, but data for these agents are sparse. The most robust data for the treatment of menorrhagia are for tranexamic acid. Most women receiving tranexamic acid in randomized trials experienced meaningful reductions in menstrual bleeding, and this translated into improved quality of life; however, these trials were not performed in patients with cancer. Further clinical trials are warranted to evaluate both preventive and therapeutic agents for menorrhagia in premenopausal women with cancer who are receiving myelosuppressive chemotherapy.

Platelet disorders in adolescents

Acquired and inherited platelet disorders can present with bleeding symptoms during adolescence. Platelet disorders include disorders of platelet number and disorders of platelet function. In adolescent females with platelet disorders, menorrhagia is a common presenting bleeding symptom. Other associated bleeding symptoms are also primarily mucocutaneous, including epistaxis and bruising. Excessive bleeding may also occur after hemostatic challenges. Diagnosis of disorders of platelet function usually requires light transmission platelet aggregometry. Management of menorrhagia in the adolescent with platelet disorders requires both hematologic and gynecologic treatment.
