Acute Menopausal Symptoms in Young Cancer Survivors Immediately following Chemotherapy.

PURPOSE: The aim of this study was to evaluate the prevalence of menopausal symptoms in young cancer survivors immediately following the completion of chemotherapy. METHODS: This prospective cohort study followed 124 young females with a new diagnosis of cancer requiring chemotherapy to assess symptoms of menopause before treatment and immediately following chemotherapy. Symptoms were compared before and after treatment using the McNemar test and between cancer patients and 133 similar-aged healthy controls using Pearson χ2 and Fisher's exact tests. RESULTS: Participants undergoing cancer therapy reported more menopausal symptoms compared to controls prior to the initiation of any treatment (hot flashes or night sweats 33 vs. 7%, p < 0.01, trouble sleeping 57 vs. 31%, p < 0.01, headaches 50 vs. 35%, p = 0.02, and decreased libido 36 vs. 16%, p < 0.01) and also reported a greater prevalence of symptoms immediately after cancer therapy compared to pretreatment prevalence (vasomotor symptoms, p < 0.01, vaginal dryness, p < 0.01, decreased concentration, p < 0.01, and body aches, p = 0.01). Cancer patients with lower anti-Müllerian hormone (AMH) levels after treatment (<0.10 ng/mL) had an increased risk of vasomotor symptoms (OR 2.2, p = 0.04), mood swings (OR 2.4, p = 0.03), feeling sad (OR 2.2, p = 0.04), trouble sleeping (OR 2.7, p = 0.02), and decreased libido (OR 3.0, p = 0.03) when controlled for age and cancer type, and the incidence of these symptoms was not affected by the use of systemic hormones or psychiatric medications. Treatment length, use of alkylating agents, pelvic radiation, and marital status were also not associated with the prevalence of menopausal symptoms. CONCLUSIONS: Premenopausal women with a new cancer diagnosis have more menopausal symptoms than females of similar age before and after cancer treatment, the effects of which are not mitigated by systemic hormone use. Decreased AMH levels were associated with an increased likelihood of reporting physiologic symptoms after therapy. IMPLICATIONS FOR CANCER SURVIVORS: This information is imperative for counseling; ultimately, improved symptom management during and after cancer therapies will improve quality of life in young cancer survivors.

A predictive model for chemotherapy-related diminished ovarian reserve in reproductive-age women.

OBJECTIVE: To develop and internally validate a clinical predictive tool to assess the likelihood that a young cancer patient will experience diminished ovarian reserve (DOR) after chemotherapy. DESIGN: Prospective cohort study. SETTING: University hospitals. PATIENT(S): Postpubertal adolescent and young adult women with a new diagnosis of cancer requiring chemotherapy. INTERVENTION: None. MAIN OUTCOME MEASURE(S): Diminished ovarian reserve after completion of and recovery from chemotherapy, defined as serum antimüllerian hormone (AMH) <1 ng/mL at 8-24 months after completion of chemotherapy. RESULT(S): A multivariable logistic regression model which includes age, cancer type, exposure to an alkylating agent, and baseline AMH value accurately predicts the diagnosis of DOR after chemotherapy with an area under the receiver operating characteristic curve of 0.89. CONCLUSION(S): Pretreatment information on age, cancer type, use of an alkylating agent, and baseline AMH levels make up a clinically useful predictive tool to identify which women are most at risk for DOR caused by chemotherapy.

Following declining human chorionic gonadotropin values in pregnancies of unknown location: when is it safe to stop?

OBJECTIVE: To determine if the pattern of decline in hCG curves can discriminate spontaneous abortion (SAB) from ectopic pregnancy (EP). DESIGN: Retrospective cohort study. SETTING: University hospitals. PATIENT(S): A total of 1,551 women with symptomatic pregnancy of unknown location (PUL) and decreasing hCG values. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Percentage change in hCG; days and visits to final diagnosis. RESULT(S): Of the 1,551 women with a PUL and declining hCG, 146 were ultimately diagnosed with EP and 1,405 with SAB. An 85% hCG drop within 4 days or a 95% hCG drop within 7 days both ruled out an EP 100% of the time. Applying the 4-day cutoff to this population would have saved 16% of the SAB population (229/1,405) a total of 2,841 person-days and 277 clinical visits. Applying the 7-day cutoff would have saved 9% of the SAB population (126/1,405) a total of 1,294 person-days and 182 clinical visits. These cutoffs were separately validated on a group of 179 EPs collected from three university clinical centers. In that population, each cutoff separately ruled out EP 100% of the time. CONCLUSION(S): The decline in serum hCG is slower in EPs than in SAB and can be used to aid clinicians in the frequency and duration of follow-up. Costs and patient time may be saved by allowing women who meet one of these criteria to be followed less frequently.
