Erectile Dysfunction in Male Survivors of Childhood Cancer-A Report From the Childhood Cancer Survivor Study.

ABSTRACT: With survival rates higher than 80%, the number of survivors from pediatric cancer continues to increase. Late effects resulting from cancer and cancer therapy are being characterized, but little information exists on sexual health for men who have survived childhood cancer.To assess erectile dysfunction (ED) in men who survived childhood and adolescent cancers and to identify potential risk factors for ED.In total, 1,622 men and 271 eligible brothers in the Childhood Cancer Survivor Study cohort completed the Male Health Questionnaire, which provided information on sexual practices and sexual function. Combined with demographic, cancer, and treatment information from medical record abstraction, results of the Male Health Questionnaire were analyzed using multivariable modeling. The International Index of Erectile Function was used to identify ED in subjects.International Index of Erectile Function.Survivors (mean age = 37.4 years, SD = 7.3 years) reported significantly lower sexual activity in the year before the survey than the brothers (mean age = 38.8 years, SD = 8.5 years) without cancer. ED was reported by 12.3% (95% CI = 10.4-14.3) of survivors and 4.2% (95% CI = 2.0-7.9) of brothers. Survivors showed significantly higher relative risk (RR) for ED (RR = 2.63, 95% CI = 1.40-4.97). In addition to older age, survivors who were exposed to higher-dose (?10 Gy) testicular radiation (RR = 3.55, 95% CI = 1.53-8.24), had surgery on the spinal cord or nerves (RR = 2.87, 95% CI = 1.36-6.05), prostate surgery (RR = 6.56, 95% CI = 3.84-11.20), or pelvic surgery (RR = 2.28, 95% CI = 1.04-4.98) were at higher risk for ED.Men who have survived childhood cancer have a greater than 2.6-fold increased risk for ED and certain cancer-specific treatments are associated with increased risk. Attention to sexual health, with its physical and emotional implications, and opportunities for early detection and intervention in these individuals could be important.

Project description:BACKGROUND:The objective of the current study was to characterize and identify factors associated with perceptions of risk of infertility among adult male survivors of childhood cancer. METHODS:A total of 1233 adult male survivors from the Childhood Cancer Survivor Study who were without a history of disease recurrence or subsequent malignancy reported their perceptions of their risk of infertility compared with men never diagnosed with cancer. Survivors were a median age of 37.8 years (range, 22.0-58.7 years) and were 28.4 years from their diagnosis (range, 21.4-39.2 years). Multivariable logistic regression evaluated factors associated with perceptions of risk. RESULTS:Overall, 35.9% of the survivors (443 of 1233 survivors) reported perceptions of their risk of infertility that were discordant with their actual risk based on previous cancer treatment exposures. Discordant perceptions were equally common among men exposed to gonadotoxic therapies (36.3%; 311 of 857 men) and those with no history of gonadotoxic exposure (35.1%; 132 of 376 men). Survivors who fathered children (odds ratio [OR], 4.14; 95% confidence interval [95% CI], 2.74-6.24), had no survivor-focused health care (OR, 3.07; 95% CI, 1.57-5.99), were nonwhite (OR, 2.28; 95% CI, 1.10-4.75), and were of lower income were more likely to report no increased risk of infertility after gonadotoxic treatment. Perceptions of increased risk of infertility among men with no history of gonadotoxic treatment were predicted by never having fathered a child (OR, 1.88; 95% CI, 1.17-3.03), recent participation in survivor-focused health care (OR, 2.11; 95% CI, 1.01-4.42), and higher educational achievement. CONCLUSIONS:Many male survivors of childhood cancer are unaware of how their cancer treatments could impact their reproductive health, underscoring the need for all patients to receive education regarding their risk of infertility throughout the continuum of cancer care.

Project description:BackgroundChildren treated for cancer are at risk for neuromuscular dysfunction, but data are limited regarding prevalence, longitudinal patterns, and long-term impact.MethodsLongitudinal surveys from 25,583 childhood cancer survivors ≥5 years from diagnosis and 5,044 siblings from the Childhood Cancer Survivor Study were used to estimate the prevalence and cumulative incidence of neuromuscular dysfunction. Multivariable models adjusted for age, sex, race, and ethnicity estimated prevalence ratios (PR) of neuromuscular dysfunction in survivors compared with siblings, and associations with treatments and late health/socioeconomic outcomes.ResultsPrevalence of neuromuscular dysfunction was 14.7% in survivors 5 years postdiagnosis versus 1.5% in siblings [PR, 9.9; 95% confidence interval (CI), 7.9-12.4], and highest in survivors of central nervous system (CNS) tumors (PR, 27.6; 95% CI, 22.1-34.6) and sarcomas (PR, 11.5; 95% CI, 9.1-14.5). Cumulative incidence rose to 24.3% in survivors 20 years postdiagnosis (95% CI, 23.8-24.8). Spinal radiotherapy and increasing cranial radiotherapy dose were associated with increased prevalence of neuromuscular dysfunction. Platinum exposure (vs. none) was associated with neuromuscular dysfunction (PR, 1.8; 95% CI, 1.5-2.1), even after excluding survivors with CNS tumors, cranial/spinal radiotherapy, or amputation. Neuromuscular dysfunction was associated with concurrent or later obesity (PR, 1.1; 95% CI, 1.1-1.2), anxiety (PR, 2.5; 95% CI, 2.2-2.9), depression (PR, 2.1; 95% CI, 1.9-2.3), and lower likelihood of graduating college (PR, 0.92; 95% CI, 0.90-0.94) and employment (PR, 0.8; 95% CI, 0.8-0.9).ConclusionsNeuromuscular dysfunction is prevalent in childhood cancer survivors, continues to increase posttherapy, and is associated with adverse health and socioeconomic outcomes.ImpactInterventions are needed to prevent and treat neuromuscular dysfunction, especially in survivors with platinum and radiation exposure.

Project description:BackgroundThe effect of many contemporary chemotherapeutic drugs on pregnancy and livebirth is not well established. We aimed to establish the effects of these drugs on pregnancy in male and female survivors of childhood cancer not exposed to pelvic or cranial radiotherapy.MethodsWe used data from a subset of the Childhood Cancer Survivor Study cohort, which followed 5-year survivors of the most common types of childhood cancer who were diagnosed before age 21 years and treated at 27 institutions in the USA and Canada between 1970 and 1999. We extracted doses of 14 alkylating and similar DNA interstrand crosslinking drugs from medical records. We used sex-specific Cox models to establish the independent effects of each drug and the cumulative cyclophosphamide equivalent dose of all drugs in relation to pregnancies and livebirths occurring between ages 15 years and 44 years. We included siblings of survivors as a comparison group.FindingsWe included 10 938 survivors and 3949 siblings. After a median follow-up of 8 years (IQR 4-12) from cohort entry or at age 15 years, whichever was later, 4149 (38%) survivors reported having or siring a pregnancy, of whom 3453 (83%) individuals reported at least one livebirth. After a median follow-up of 10 years (IQR 6-15), 2445 (62%) siblings reported having or siring a pregnancy, of whom 2201 (90%) individuals reported at least one livebirth. In multivariable analysis, survivors had a decreased likelihood of siring or having a pregnancy versus siblings (male survivors: hazard ratio [HR] 0·63, 95% CI 0·58-0·68; p<0·0001; female survivors: 0·87, 0·81-0·94; p<0·0001) or of having a livebirth (male survivors: 0·63, 0·58-0·69; p<0·0001; female survivors: 0·82, 0·76-0·89; p<0·0001). In male survivors, reduced likelihood of pregnancy was associated with upper tertile doses of cyclophosphamide (HR 0·60, 95% CI 0·51-0·71; p<0·0001), ifosfamide (0·42, 0·23-0·79; p=0·0069), procarbazine (0·30, 0·20-0·46; p<0·0001) and cisplatin (0·56, 0·39-0·82; p=0·0023). Cyclophosphamide equivalent dose in male survivors was significantly associated with a decreased likelihood of siring a pregnancy (per 5000 mg/m(2) increments: HR 0·82, 95% CI 0·79-0·86; p<0·0001). However, in female survivors, only busulfan (<450 mg/m(2) HR 0·22, 95% CI 0·06-0·79; p=0·020; ≥450 mg/m(2) 0·14, 0·03-0·55; p=0·0051) and doses of lomustine equal to or greater than 411 mg/m(2) (0·41, 0·17-0·98; p=0·046) were significantly associated with reduced pregnancy; cyclophosphamide equivalent dose was associated with risk only at the highest doses in analyses categorised by quartile (upper quartile vs no exposure: HR 0·85, 95% CI 0·74-0·98; p=0·023). Results for livebirth were similar to those for pregnancy.InterpretationGreater doses of contemporary alkylating drugs and cisplatin were associated with a decreased likelihood of siring a pregnancy in male survivors of childhood cancer. However, our findings should provide reassurance to most female survivors treated with chemotherapy without radiotherapy to the pelvis or brain, given that chemotherapy-specific effects on pregnancy were generally few. Nevertheless, consideration of fertility preservation before cancer treatment remains important to maximise the reproductive potential of all adolescents newly diagnosed with cancer.FundingNational Cancer Institute, National Institutes of Health, and the American Lebanese-Syrian Associated Charities.
