PURPOSE Adolescents and young adults (AYAs) diagnosed with cancer face numerous physical, psychosocial, and practical challenges. This article describes the health-related quality of life (HRQOL) and associated demographic and health-related characteristics of this developmentally diverse population. PATIENTS AND METHODS Data are from the Adolescent and Young Adult Health Outcomes and Patient Experience (AYA HOPE) study, a population-based cohort of 523 AYA patients with cancer, ages 15 to 39 years at diagnosis from 2007 to 2009. Comparisons are made by age group and with general and healthy populations. Multiple linear regression models evaluated effects of demographic, disease, health care, and symptom variables on multiple domains of HRQOL using the Pediatric Quality of Life Inventory (PedsQL) and the Short-Form Health Survey 12 (SF-12). RESULTS Overall, respondents reported significantly worse HRQOL across both physical and mental health scales than did general and healthy populations. The greatest deficits were in limitations to physical and emotional roles, physical and social functioning, and fatigue. Teenaged patients (ages 15 to 17 years) reported worse physical and work/school functioning than patients 18 to 25 years old. Regression models showed that HRQOL was worse for those in treatment, with current/recent symptoms, or lacking health insurance at any time since diagnosis. In addition, sarcoma patients, Hispanic patients, and those with high school or lower education reported worse physical health. Unmarried patients reported worse mental health. CONCLUSION Results suggest that AYAs with cancer have major decrements in several physical and mental HRQOL domains. Vulnerable subgroups included Hispanic patients, those with less education, and those without health insurance. AYAs also experienced higher levels of fatigue that were influenced by current symptoms and treatment. Future research should explore ways to address poor functioning in this understudied group.

The majority of children, adolescents, and young adults diagnosed with cancer will become long-term survivors. Although cancer therapy is associated with many adverse effects, one of the primary concerns of young male cancer survivors is reproductive health. Future fertility is often the focus of concern; however, it must be recognized that all aspects of male health, including pubertal development, testosterone production, and sexual function, can be impaired by cancer therapy. Although pretreatment strategies to preserve reproductive health have been beneficial to some male patients, many survivors remain at risk for long-term reproductive complications. Understanding risk factors and monitoring the reproductive health of young male survivors are important aspects of follow-up care. The Childrens Oncology Group Long-Term Follow-Up Guidelines for Survivors of Childhood, Adolescent, and Young Adult Cancer (COG-LTFU Guidelines) were created by the COG to provide recommendations for follow-up care of survivors at risk for long-term complications. The male health task force of the COG-LTFU Guidelines, composed of pediatric oncologists, endocrinologists, nurse practitioners, a urologist, and a radiation oncologist, is responsible for updating the COG-LTFU Guidelines every 2 years based on literature review and expert consensus. This review summarizes current task force recommendations for the assessment and management of male reproductive complications after treatment for childhood, adolescent, and young adult cancers. Issues related to male health that are being investigated, but currently not included in the COG-LTFU Guidelines, are also discussed. Ongoing investigation will inform future COG-LTFU Guideline recommendations for follow-up care to improve health and quality of life for male survivors.

PURPOSE Since 1989, we have used the complete primary repair of exstrophy surgical technique to reconstruct the genitourinary system of children born with the exstrophy-epispadias complex based on the assumption that this complex represents a malformation. We initially reported using this technique in 1999. We now report a longer term followup of this initial group as well as surgical outcomes in a larger group of children who have undergone this repair for classic bladder exstrophy. MATERIALS AND METHODS Since 1989, we have prospectively followed 39 children who underwent the complete primary repair of exstrophy technique to construct classic bladder exstrophy. Median followup in the original group of patients that we reported in 1999 is 106 months. Median followup in the entire series is 58 months. RESULTS Of boys and girls 4 years or older 74% have achieved daytime continence with volitional voiding. Of boys and girls 20% and 43%, respectively, have achieved primary urinary continence without the need for bladder neck reconstruction. An additional 18% of boys and girls achieved continence with only bladder neck injection following complete primary repair of exstrophy. Complications developed in 7 of the 39 children (18%) in the entire series. CONCLUSIONS Urinary continence has been consistently achieved with this form of exstrophy repair. Primary continence without the need for further reconstruction is possible. The results of this patient series have caused us to modify the complete primary repair of exstrophy technique in an effort to improve the rate of primary urinary continence.

PURPOSE Augmentation gastrocystoplasty has been proposed as an alternative to enterocystoplasty because of potential benefits, including decreased risk of mucus production, stone formation and urinary tract infections. Although cancer has rarely been reported in this patient population, it is a well recognized potential risk of all augmentation cystoplasties. To define better the risk of malignancy associated with gastric augmentation and the appropriate surveillance protocol for these patients, we describe our experience in 2 patients with metastatic adenocarcinoma following gastrocystoplasty. MATERIALS AND METHODS We retrospectively reviewed the charts of all patients who had undergone augmentation gastrocystoplasty between 1990 and 1994. Of the 72 patients identified 2 were diagnosed with a primary malignancy arising from the augmented bladder. Charts were reviewed for medical history, clinical outcomes and pathology. RESULTS Two patients were identified with a primary bladder malignancy after gastrocystoplasty. Both patients had metastatic disease at initial presentation. Neither patient had a history of gross hematuria, recurrent urinary tract infections or pain before initial presentation. Mean patient age at augmentation was 5.5 years. Mean age at diagnosis of malignancy was 19.5 years, with a mean time from augmentation of 14 years. CONCLUSIONS Although the risk of bladder cancer is low after gastric augmentation, the effects may be life threatening. Therefore, we advocate routine annual surveillance with cystoscopy, bladder biopsy and upper tract imaging in all patients who have undergone augmentation gastrocystoplasty.

BACKGROUND The 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. METHODS We 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. FINDINGS We 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. INTERPRETATION Greater 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.

Infertility is an unfortunate treatment‐related consequence for some pediatric malignancies as well as some non‐malignant conditions treated with stem cell transplant. Unlike pubertal males, prepubertal males cannot produce semen for cryopreservation. This manuscript reports on the acceptability and safety of a multi‐institutional protocol for offering testicular tissue cryopreservation to families of prepubertal male children at highest risk for infertility. Data on decision influences, decision‐making control, and emotional state when considering this option are described.

BACKGROUND & AIMS Children who receive cancer therapy experience numerous acute gastrointestinal (GI) toxicities. However, the long-term GI consequences have not been extensively studied. We evaluated the incidence of long-term GI outcomes and identified treatment-related risk factors. METHODS Upper GI, hepatic, and lower GI adverse outcomes were assessed in cases from participants in the Childhood Cancer Survivor Study, a study of 14,358 survivors of childhood cancer who were diagnosed between 1970 and 1986; data were compared with those from randomly selected siblings. The median age at cancer diagnosis was 6.8 years (range, 0-21.0 years), and the median age at outcome assessment was 23.2 years (5.6-48.9 years) for survivors and 26.6 years (1.8-56.2 years) for siblings. Rates of self-reported late GI complications (occurred 5 or more years after cancer diagnosis) were determined and associated with patient characteristics and cancer treatments, adjusting for age, sex, and race. RESULTS Compared with siblings, survivors had increased risk of late-onset complications of the upper GI tract (rate ratio [RR], 1.8; 95% confidence interval [CI], 1.6-2.0), liver (RR, 2.1; 95% CI, 1.8-2.5), and lower GI tract (RR, 1.9; 95% CI, 1.7-2.2). The RRs for requiring colostomy/ileostomy, liver biopsy, or developing cirrhosis were 5.6 (95% CI, 2.4-13.1), 24.1 (95% CI, 7.5-77.8), and 8.9 (95% CI, 2.0-40.0), respectively. Older age at diagnosis, intensified therapy, abdominal radiation, and abdominal surgery increased the risk of certain GI complications. CONCLUSIONS Individuals who received therapy for cancer during childhood have an increased risk of developing GI complications later in life.

Background: There is limited literature on strategies to overcome the barriers to sperm banking among adolescent and young adult (AYA) males with cancer. By standardizing our process for offering sperm banking to AYA males before cancer treatment, we aimed to improve rates of sperm banking at our institution. Materials and Methods: Continuous process improvement is a technique that has recently been applied to improve health care delivery. We used continuous process improvement methodologies to create a standard process for fertility preservation for AYA males with cancer at our institution. We compared rates of sperm banking before and after standardization. Results: In the 12-month period after implementation of a standardized process, 90% of patients were offered sperm banking. We demonstrated an 8-fold increase in the proportion of AYA males’ sperm banking, and a 5-fold increase in the rate of sperm banking at our institution. Discussion: Implementation of a standardized process for sperm banking for AYA males with cancer was associated with increased rates of sperm banking at our institution. This study supports the role of standardized health care in decreasing barriers to sperm banking.

BACKGROUND There has been little improvement in the survival of adolescent and young adult (AYA) cancer patients aged 15 to 39 years relative to other age groups, raising the question of whether such patients receive appropriate initial treatment. METHODS We examined receipt of initial cancer treatment for a population-based sample of 504 AYAs diagnosed in 2007-2008 with acute lymphoblastic leukemia (ALL), Hodgkins or non-Hodgkins lymphoma, germ cell cancer, or sarcoma. Registry data, patient surveys, and detailed medical record reviews were used to evaluate the association of patient demographic, socioeconomic, and health care setting characteristics with receipt of appropriate initial treatment, which was defined by clinical specialists in AYA oncology based on adult guidelines and published literature available before 2009 and analyzed with multivariable logistic regression. All statistical tests were two-sided. RESULTS Approximately 75% of AYA cancer patients in our sample received appropriate treatment, 68% after excluding stage I male germ cell patients who all received appropriate treatment. After this exclusion, appropriate treatment ranged from 79% of sarcoma patients to 56% of ALL patients. Cancer type (P < .01) and clinical trial participation (P = .04) were statistically significantly associated with appropriate treatment in multivariable analyses. Patients enrolled in clinical trials were more likely to receive appropriate therapy relative to those not enrolled (78% vs 67%, adjusted odds ratio = 2.6, 95% confidence interval = 1.1 to 6.4). CONCLUSIONS Except for those with early stage male germ cell tumors, approximately 30% (or 3 in 10) AYA cancer patients did not receive appropriate therapy. Further investigation is required to understand the reasons for this potential shortfall in care delivery.
