Abstract
Long-term survivors of cancer (ie, the patient who is considered cured or for whom the disease is under long-term control and unlikely to recur) are at an increased risk of developing endocrine complications such as hypothalamic-pituitary dysfunctions, hypogonadisms, osteoporosis, or metabolic disorders, particularly when intensive tumour-directed therapies are applied. Symptom severity associated with these conditions ranges from mild and subclinical to highly detrimental, affecting individual health and quality of life. Although they are usually manageable, many of these endocrine pathologies remain underdiagnosed and untreated for years. To address this challenge, a higher degree of awareness, standardised screening tools, comprehensible treatment algorithms, and a close collaborative effort between endocrinologists and oncologists are essential to early identify patients who are at risk, and to implement appropriate treatment protocols. This Review highlights common symptoms and conditions related to endocrine disorders among survivors of adult-onset cancer, provides a summary of the currently available practice guidelines, and proposes a practical approach to diagnose affected patients among this group.

Abstract
Dropped head syndrome (DHS) is an impairment of neck extension resulting in a chin-on-chest deformity. DHS is rarely seen but a major hindrance to daily function in affected patients. DHS has been associated with movement disorders, neuromuscular disorders, and electrolyte and endocrine abnormalities. DHS has also been seen in survivors of Hodgkin lymphoma (HL) years after irradiation. HL survivors are also at risk for endocrine hypogonadism after chemotherapy. We present the case of a 58-year-old male HL survivor with dropped head and limited strength in his atrophic neck extensor muscles. Laboratory testing and imaging, nerve conduction studies, electromyography, and muscle biopsy of the neck extensors revealed myopathic and neurogenic changes. Conservative management was unsuccessful. With a desire to avoid surgical fixation, he asked his primary care physician to check his testosterone levels, which returned as low normal. Within 4 months of starting testosterone therapy, he no longer experienced dropped head.

Abstract
Context Testicular germ cell tumour (TGCT) survivors are potentially at risk of developing osteoporosis, because of increased risk for disturbed bone remodelling associated with hypogonadism and anti-cancer treatment. A number of studies show bone loss and increased fracture risk in TGCT survivors, but data are scarce. There are no clinical guidelines or recommendations issued to address skeletal health in this group of patients potentially at high risk for osteoporosis. Objective To conduct a systematic review of available literature addressing bone health in TGCT patients. Subgroup analysis was performed to identify risk factors for bone loss and increased fracture risk. Evidence Acquisition Relevant databases, including MEDLINE, Embase and the Cochrane Library, including all English written comparative studies addressing bone health in TGCT patients, were searched up to December 2021 and a narrative synthesis was undertaken. Risk of bias (RoB) was assessed using Cochrane ROBINS-I tool. Evidence Synthesis Ten studies (eight cross-sectional and two longitudinal), recruiting a total of 1997 unique TGCT patients, were identified and included in the analysis. Bone health was reported in various ways in different studies, and subgroups were defined heterogeneously, resulting in a widely varying prevalence of osteoporosis of up to 73.2% of patients. Six studies reported low BMD associated with higher luteinizing hormone levels and one study showed a correlation between follow up duration and bone loss. Conclusions TGCT survivors are at risk of developing osteoporosis and sustaining fragility fractures. Chemotherapy, pituitary-gonadal axis dysfunction and ageing are key risk factors, although available data are scarce. With increasing survival of TGCT patients, a clear unmet need has been identified to systematically evaluate and monitor skeletal health in larger numbers of survivors in order to develop best clinical practice guidelines to manage the insidious but potentially preventable and treatable skeletal complications of TGCT.

Abstract
PURPOSE OF REVIEW Hypogonadism is highly prevalent among not only patients with a history of prior treatment for cancer, but also among those patients with a new oncologic diagnosis who have not yet received any cancer therapy. Hypogonadism can cause a wide array of signs and symptoms including: deceased muscle mass; increased fat mass; decreased energy, mood, and overall sense of well being; diminished bone mineral density; infertility; and impaired libido and sexual function. This purpose of this manuscript is to review the mechanisms by which cancer and oncologic treatment regimens can adversely affect the hypothalamic pituitary gonadal axis, resulting in hypogonadism. Risks and benefits associated with the treatment of testosterone deficiency are also discussed, which are important considerations for clinicians caring for affected patients. RECENT FINDINGS Hypogonadism has a high prevalence in the setting of cancer and is an important survivorship issue. Recent randomized controlled trials confirm testosterone's therapeutic benefits in terms of sexual function, mood body composition, and bone health, but the specific benefits in terms of quality of life are less clear. SUMMARY More prospective studies are needed to further delineate the risks, benefits, and overall outcomes of testosterone replacement therapy in patients with cancer and cancer survivors.

Low bone mineral density is associated with hypogonadism and cranial irradiation in male childhood cancer survivors. Osteoporos Int 2020; 31:1261-1272. [PMID: 32008156 PMCID: PMC7280350 DOI: 10.1007/s00198-020-05285-4] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2019] [Accepted: 01/06/2020] [Indexed: 11/17/2022]
Abstract
UNLABELLED We investigated if bone mineral density was related to testosterone deficiency and/or previous cancer treatment in men who were childhood cancer survivors. Men with untreated testosterone deficiency or previous treatment with cranial irradiation were at increased risk of impaired bone health. Prevention of osteoporosis should be considered in their follow-up. INTRODUCTION Childhood cancer survivors (CCS) are at increased risk of hypogonadism. Reduced bone mineral density (BMD) has been reported in CCS but it is unclear whether this is due to hypogonadism or a direct effect of cancer therapy. This study investigated BMD in CCS, and association with hypogonadism, previous treatment and cancer type. METHODS Investigation of 125 CCS (median age 33.7 at inclusion; 9.6 at diagnosis) and 125 age-matched population controls. Serum testosterone and luteinizing hormone were assayed and BMD at total hip and lumbar spine L1-L4 measured. The mean difference in BMD (g/cm2; 95% CI) between CCS and controls was analysed. Odds ratios (OR; 95% CI) for low BMD were also calculated. RESULTS Overall, BMD in the CCS cohort did not significantly differ from controls. However, compared with eugonadal CCS, the CCS with untreated hypogonadism had lower BMD at the hip (mean difference - 0.139 (- 0.210; - 0.067); p < 0.001) and spine (- 0.102 (- 0.174; - 0.030); p = 0.006). They also had a higher risk of low hip BMD (OR 4.1 (1.3; 14); p = 0.018). CCS treated with cranial irradiation also had lower BMD (hip - 0.076 (- 0.133; - 0.019); p = 0.009; spine - 0.071 (- 0.124; - 0.018); p = 0.009) compared with controls. The latter associations remained statistically significant after adjustment for hypogonadism. CONCLUSIONS CCS with hypogonadism or previously treated with cranial irradiation are at increased risk of impaired bone health. Prevention of osteoporosis should be considered as an important part in future follow-up of these men.

Abstract
The number of patients surviving ≥5 years after initial cancer diagnosis has significantly increased during the last decades due to considerable improvements in the treatment of many cancer entities. A negative consequence of this is that the emergence of long-term sequelae and endocrine disorders account for a high proportion of these. These late effects can occur decades after cancer treatment and affect up to 50% of childhood cancer survivors. Multiple predisposing factors for endocrine late effects have been identified, including radiation, sex, and age at the time of diagnosis. A systematic literature search has been conducted using the PubMed database to offer a detailed overview of the spectrum of late endocrine disorders following oncological treatment. Most data are based on late effects of treatment in former childhood cancer patients for whom specific guidelines and recommendations already exist, whereas current knowledge concerning late effects in adult-onset cancer survivors is much less clear. Endocrine sequelae of cancer therapy include functional alterations in hypothalamic-pituitary, thyroid, parathyroid, adrenal, and gonadal regulation as well as bone and metabolic complications. Surgery, radiotherapy, chemotherapy, and immunotherapy all contribute to these sequelae. Following irradiation, endocrine organs such as the thyroid are also at risk for subsequent malignancies. Although diagnosis and management of functional and neoplastic long-term consequences of cancer therapy are comparable to other causes of endocrine disorders, cancer survivors need individually structured follow-up care in specialized surveillance centers to improve care for this rapidly growing group of patients.

Abstract
BACKGROUND Compensated Leydig cell (LC) dysfunction, defined by elevated serum levels of luteinizing hormone (LH) in combination with normal total testosterone levels, is common in testicular cancer (TC) survivors. The association between this condition and quality of life is unknown. We aimed to clarify if TC survivors with compensated LC dysfunction have impaired quality of life. PATIENTS AND METHODS In total, 147 long-term TC survivors were included. On the basis of a single measurement of testosterone and LH, compensated LC dysfunction was defined by age-adjusted levels of LH above normal range combined with testosterone levels within the normal range. Quality-of-life outcomes including sexual function, anxiety and depression, fatigue, and overall self-evaluated quality of life were compared between patients with and without compensated LC dysfunction with adjustment for age. RESULTS In total, 60 TC survivors had compensated LC dysfunction and 87 TC survivors had normal LC function. TC survivors with compensated LC dysfunction had lower serum levels of total testosterone (11 vs. 13 nmol/L, P = .016). There were no significant differences in the investigated quality-of-life outcomes (anxiety, depression, sexual function, fatigue) between the 2 groups. CONCLUSION Compensated LC dysfunction in TC survivors was not associated with symptoms of depression, anxiety, sexual dysfunction, fatigue, or impaired overall self-evaluated quality of life. Limitations include the few cases of symptoms of depression (n = 7). Our findings do not suggest that testosterone substitution is indicated in TC survivors with compensated LC dysfunction.

Abstract
Improved understanding of the pathogenesis and natural history of many urologic disorders, as well as advances in fertility preservation techniques, has increased the awareness of and options for management of fertility threats in pediatric patients. In children, fertility may be altered by oncologic conditions, by differences in sexual differentiation, by gonadotoxic drugs and other side effects of treatment for nonurologic disorders, and by urologic conditions, such as varicocele and cryptorchidism. Although fertility concerns are best addressed in a multidisciplinary setting, pediatric urologists should be aware of the underlying pathophysiology and management options to properly counsel and advocate for patients.

Biomed Pharmacother 2017; 95:1619-1630.

Abstract
Busulphan (Bu), an alkylating agent used for bone marrow and spermatogonial stem cell transplantation (SSCT), impairs Sertoli (SC) cells, which are necessary for the spermatogonial stem cell (SSC) homing during transplantation. As Leydig (LC) and peritubular myoid (PMC) cells are essential for SC support and maintenance of spermatogonial niche, we evaluated the impact of Bu on the LC and PMC structural integrity. Vitamin B12 (B12) has demonstrated beneficial effects against drug-induced testicular changes; thus, we also examined whether this vitamin is able to stimulate spermatogonia mitotic activity and prevent Bu-induced germ cell death. Rats received 10mg/kg of Bu in the 1st and 4th days, and daily B12 supplementation during Bu treatment and for 6days after the last injection of Bu (Bu-6d), totaling 10days of treatment. Other animals received the same treatment as Bu-6d, and B12 supplementation (Bu+7dB12) or saline (Bu+7dS) for 7 more days, totaling 17days of treatment. Serum testosterone levels were measured. In the historesin-embedded testis sections, the seminiferous tubule and epithelial areas were measured, and the number of spermatogonia and PMC was quantified. Actin and 17β-HSD6 immunofluorescence was detected, and the number of TUNEL-positive LC and germ cells was computed. In Bu-6d, PMC number reduced, and a weak actin immunoexpression and death in these cells was observed. The testosterone levels reduced, and the interstitial tissue showed a weak 17β-HSD6 immunoexpression and increased number of TUNEL-positive LC. In Bu+7dB12, the number of spermatogonia was higher than in Bu-6d and Bu+7dS, and the number of TUNEL-positive germ cells was significantly lower than in Bu+7dS. Bu exerts a harmful impact on PMC and LC, reducing the testosterone levels. Vitamin B12 prevents significantly Bu-induced germ cell death and stimulates spermatogonia proliferation, being a useful strategy for the enrichment of SSC in vitro and an adjuvant therapy for spermatogenesis recovery in oncologic patients.

Abstract
It is well recognized that bone loss accelerates in hypogonadal states, with female menopause being the classic example of sex hormones affecting the regulation of bone metabolism. Underrepresented is our knowledge of the clinical and metabolic consequences of overt male hypogonadism, as well as the more subtle age-related decline in testosterone on bone quality. While menopause and estrogen deficiency are well-known risk factors for osteoporosis in women, the effects of age-related testosterone decline in men on bone health are less well known. Much of our knowledge comes from observational studies and retrospective analysis on small groups of men with variable causes of primary or secondary hypogonadism and mild to overt testosterone deficiencies. This review aims to present the current knowledge of the consequences of adult male hypogonadism on bone metabolism. The direct and indirect effects of testosterone on bone cells will be explored as well as the important differences in male osteoporosis and assessment as compared to that in females. The clinical consequence of both primary and secondary hypogonadism, as well as testosterone decline in older males, on bone density and fracture risk in men will be summarized. Finally, the therapeutic options and their efficacy in male osteoporosis and hypogonadism will be discussed.

Abstract
Purpose Few studies have addressed gonadal and sexual dysfunctions in childhood cancer survivors. We evaluated the prevalence rates and risk factors for gonadal failure among adolescent/young adult childhood cancer survivors and their sexual function. Materials and Methods Subjects were childhood cancer survivors aged 15-29 years who had completed therapy more than 2 years ago. Demographic and medical characteristics were obtained from the patients’ medical records. In addition, hormonal evaluation and semen analysis were performed and sexual function was evaluated via questionnaire. Results The study included 105 survivors (57 males, 48 females), of which 61 were adults (age > 19 years) and 44 were adolescents. In both males and females, the proportion of survivors with low sex hormone levels did not differ among age groups or follow-up period. Thirteen female subjects (27.1%) needed sex hormone replacement, while five males subjects (8.8%) were suspected of having hypogonadism, but none were receiving sex hormone replacement. Of 27 semen samples, 14 showed azospermia or oligospermia. The proportion of normospermia was lower in the high cyclophosphamide equivalent dose (CED) group (CED ≥ 8,000 mg/m2) than the low CED group (27.3% vs. 62.5%, p=0.047). Among adults, none were married and only 10 men (35.7%) and eight women (34.3%) were in a romantic relationship. Though a significant proportion (12.0% of males and 5.3% of females) of adolescent survivors had experienced sexual activity, 13.6% had not experienced sex education. Conclusion The childhood cancer survivors in this study showed a high prevalence of gonadal/sexual dysfunction; accordingly, proper strategies are needed to manage these complications.

Abstract
Osteoporotic fractures are an important public health problem with significant individual and societal costs. In addition to the major risk factors for osteoporotic fracture, low bone mineral density (BMD), age, low body weight and history of fracture or falls, some drugs are now considered to be important secondary risk factor for bone loss and fracture, particularly amongst predisposed individuals. Currently available data are often generated from small observational clinical studies, making risk assessment and development of management guidelines difficult. In many cases, the exposed population has a low baseline risk for fracture and additional assessment and treatment may not be necessary. In this review, we focus on drugs other than glucocorticoids identified as potentially causing adverse skeletal effects, summarizing the existing evidence from preclinical and clinical studies, and suggest recommendations for patient management.

Abstract
Cytotoxic anticancer chemotherapy affects pituitary-testicular hormonal axis in humans and in animals. This study investigated the effects on Leydig cells of three cycles of bleomycin, etoposide and cisplatin (0.75, 7.5, and 1.5mg/kg, respectively; BEP) chemotherapy in rat testis. The chemotherapy has induced hyperplasia of and degenerative changes in Leydig cells at the end of BEP exposure, which remained so even after a recovery time of 63 days. The increased testicular oxidative stress at the end of the chemotherapy returned to normal level after the recovery time. The chemotherapy has stimulated the transcription of scavenger receptor class type-B1 (SCARB1), steroidogenic acute-regulatory protein (StAR), cytochrome P450 cholesterol side-chain cleavage (CYP11A1), CYP17A1, and inhibited that of 17β-hydroxysteroid dehydrogenase (HSD17B6) and CYP19A1 in association with increased cholesterol and decreased testosterone levels. Even after the recovery time, the chemotherapy still had inhibitory effects on the transcription of all of the above genes in addition to luteinizing hormone receptor and HSD3B1, but not on the StAR gene. The cholesterol and testosterone levels also did not show any significant differences with the control group. The decreased testosterone level at the end of chemotherapy was probably due to inhibition of HSD3B1 and HSD17B6 genes. In conclusion, clinically relevant dose-levels and treatment protocols of BEP chemotherapy adversely affect Leydig cell function. The BEP chemotherapy inhibits the transcription of steroidogenic enzymes and that these effects sustain over an extended period of time without returning to normal levels.

Abstract
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 Children's 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.

Abstract
BACKGROUND Negative health outcomes of chronic fatigue (CF) in disease-free cancer survivors are mainly unexplored. Aims of this study were to examine mortality and causes of death in Hodgkin's lymphoma survivors (HLSs) compared to controls from the general population, and to explore if CF was associated with increased mortality. METHODS HLSs (n=557) invited to participate in a survey on late effects in 1994 were divided into three groups: participants without CF (n=329), participants with CF (n=113), non-participants (n=98). Controls matched for gender and age were drawn from the general population (five per HLSs, n=2785). Observation time was calculated from 1st January 1994 until date of death or cut-off at 1st January 2007. Kaplan-Meier plots were used for univariate analyses and Cox models for multiple covariates. RESULTS Compared to controls HLSs had nearly five times higher mortality (HR=4.93; 95% confidence interval [CI]: 3.91-6.21) and the mortality rate of HLSs was higher than the rate of their controls for the entire observation period. Mortality was increased in all groups: participants with CF: HR=4.85 (95% CI: 3.02-7.77), participants without CF: HR=4.35 (95% CI: 3.16-6.00), non-participants: HR=9.45 (95% CI: 5.44-16.41). Compared to the controls HLSs had over six times increased mortality of cancer (HR: 6.6, 95% CI: 4.7-9.2) and almost five times increased mortality of cardiovascular diseases (HR: 4.9, 95% CI: 3.1-7.9). CONCLUSIONS HLSs had almost five-time increased mortality compared to controls. CF was not associated with increased mortality rate. The high mortality among the non-participating HLSs indicates that serious health problems are underestimated in this group. This has implications for the interpretation of surveys in cancer survivors.

Abstract
CONTEXT Pediatric cancer treatment may imply an increased risk of hypogonadism, leading to metabolic disorders and osteoporosis. Such complications are potentially preventable. OBJECTIVE The aim of this study was to assess diagnosis- and treatment-dependent risk of hypogonadism in male childhood cancer survivors (CCS). DESIGN Male CCS who were treated during the period 1970-2002 and who in 2004 were 18-45 yr of age were eligible. SETTING The study was conducted in a university hospital clinic. PATIENTS A consecutive group of CCS treated at Lund University Hospital was selected for the study, of whom 151 (38%) agreed to participate. Furthermore, 141 healthy fertile men served as controls. INTERVENTIONS We measured serum levels of free and total testosterone, SHBG, and LH. MAIN OUTCOME MEASURES Odds ratios (OR) for biochemical hypogonadism, defined as total testosterone less than 10 nmol/liter and/or LH above 10 IU/liter, were calculated and related to type of cancer, treatment received, as well as testicular volume. RESULTS Hypogonadism was more commonly detected in CCS than in controls (OR, 6.7; 95% CI, 2.7, 17). The increased presence of hypogonadism was noted in the following treatment groups: brain surgery, chemotherapy (with and without radiotherapy), and testicular irradiation. Low total testicular volume (<or=24 ml) was associated with a high risk of hypogonadism (OR, 31; 95% CI, 11, 92). CONCLUSION Adult male survivors of childhood cancer are at risk of hypogonadism, which should be acknowledged in the long-term follow-up of these men.

Abstract
Gonadal function was assessed in male lymphoma survivors based on serum hormone levels (LH, FSH, testosterone, SHBG), and was related to treatment, age and observation time. Male patients ⩽50 years at diagnosis treated for Hodgkin's (HL) and/or non-Hodgkin's lymphoma (NHL) at the Norwegian Radium Hospital from 1 January 1980 to 31 December 2002 were included. Five treatment groups were defined: 1: radiotherapy only and/or low gonadotoxic chemotherapy (both HL and NHL)(‘No/low’), 2: medium gonadotoxicity chemotherapy for NHL (‘med-NHL’), 3: medium gonadotoxicity chemotherapy for HL (‘med-HL’), 4: highly gonadotoxic chemotherapy for NHL (‘high-NHL’), 5: highly gonadotoxic chemotherapy for HL (‘high-HL’). Gonadal hormone levels were categorised into three groups: 1: All gonadal hormones within normal range (normal), 2: Isolated elevated FSH, with LH, SHBG and testosterone within normal range (exocrine hypogonadism), 3: Testosterone below and/or LH above normal range (endocrine hypogonadism). One hundred and forty-four (49%) of the patients had normal gonadal hormones, 60 (20%) displayed exocrine hypogonadism and almost one-third (n=90, 30%) had endocrine hypogonadism. Compared to those treated with no/low gonadotoxic chemotherapy patients from all other treatment groups had significantly elevated risk for exocrine hypogonadism. Patients from the other treatment groups, except those in the med-NHL group, also had significantly elevated risk for endocrine hypogonadism compared with the group treated with no/low gonadotoxic chemotherapy. Men aged above 50 years at survey were about five times more likely to have endocrine hypogonadism compared with those less than 40 years. Because of the adverse health effects following long-lasting endocrine hypogonadism, gonadal hormones should be assessed regularly in male lymphoma survivors, especially after treatment with alkylating agents and high-dose chemotherapy with autologous stem cell support and in male patients who are 50 years and older.

Abstract
BACKGROUND Testosterone replacement in hypogonadal males improves body composition, sexual function, and health-related quality of life. Male cancer survivors are at risk of androgen deficiency; however, when and in whom testosterone should be replaced remain unanswered questions. OBJECTIVE The aim of our study was to define the prevalence of androgen deficiency in this patient group through assessment of testosterone levels and related measures. DESIGN This was a cross-sectional, observational study of cases and controls. We recruited 176 cancer survivors and 213 controls, aged 25-45 yr. RESULTS Of cancer survivors, 97% had received chemotherapy and 40% radiotherapy. Cancer survivors had lower total testosterone (tT) levels than controls (mean difference 2.67 nmol/liter; 95% confidence interval 1.58-3.76; P = 0.003), and 24 of 176 (13.6%; 95% confidence interval 9.3-19.5) had a tT less than 10 nmol/liter, which was less than 2.5% centile for controls. Cancer survivors had a greater fat mass, higher fasting insulin and glucose levels, increased fatigue, and reduced sexual function and health-related quality of life. In both cohorts, the tT correlated negatively with insulin levels and negatively with body fat mass; however, the difference in tT between them was independent of fat mass. We measured tT and SHBG and calculated bioavailable testosterone. The changes in calculated bioavailable testosterone were similar to tT. CONCLUSIONS A significant proportion of young male cancer survivors had a frankly low tT associated with an increased fat mass and insulin level compared with controls. These factors would be predicted to improve in response to testosterone replacement therapy and provide a powerful argument for an interventional study of testosterone therapy in young male cancer survivors.

Abstract
The aim of this study is to describe the growth, pubertal development, and gonadal function of a cohort of 30 sickle cell disease children who underwent bone marrow transplantation. They all received the standard pretransplant conditioning regimen of busulfan (14 or 16 mg/kg) and cyclophosphamide (200 mg/kg). Growth was normal both before and after transplant. Seven out of 10 girls had severe ovarian failure and requirement for estrogen replacement. Three out of 10 girls recovered some ovarian function posttransplant, with spontaneous pubertal development, menses, and 1 successful normal pregnancy. Follicle-stimulating hormone (FSH) serum levels were very high during spontaneous puberty and slowly normalized thereafter in these 3 patients. The 3 girls with ovarian function recovery differed from the 7 others by the lower busulphan dose of the conditioning regimen they received (14 rather than 16 mg/kg). All boys showed spontaneous pubertal development. However, most of them had small testis and elevated serum FSH levels, reflecting germinal epithelium damage. Testosterone level was low normal and luteinizing hormone elevated, reflecting Leydig cell insufficiency. In conclusion, 7/10 girls had complete gonadal failure and most of the boys had spontaneous puberty but germinal epithelial failure. Serum FSH levels showed important variations over time in the same patient.

Abstract
Mutations in PINK1 cause the mitochondrial-related neurodegenerative disease Parkinson's. Here we investigate whether obesity, type 2 diabetes, or inactivity alters transcription from the PINK1 locus. We utilized a cDNA-array and quantitative real-time PCR for gene expression analysis of muscle from healthy volunteers following physical inactivity, and muscle and adipose tissue from nonobese or obese subjects with normal glucose tolerance or type 2 diabetes. Functional studies of PINK1 were performed utilizing RNA interference in cell culture models. Following inactivity, the PINK1 locus had an opposing regulation pattern (PINK1 was down-regulated while natural antisense PINK1 was up-regulated). In type 2 diabetes skeletal muscle, all transcripts from the PINK1 locus were suppressed and gene expression correlated with diabetes status. RNA interference of PINK1 in human neuronal cell lines impaired basal glucose uptake. In adipose tissue, mitochondrial gene expression correlated with PINK1 expression although remained unaltered following siRNA knockdown of Pink1 in primary cultures of brown preadipocytes. In conclusion, regulation of the PINK1 locus, previously linked to neurodegenerative disease, is altered in obesity, type 2 diabetes and inactivity, while the combination of RNAi experiments and clinical data suggests a role for PINK1 in cell energetics rather than in mitochondrial biogenesis.

Abstract
PURPOSE There are concerns over the late effects of cancer therapy, including accelerated bone loss leading to increased risk of osteoporosis. Treatment-related bone loss is well recognized in breast and prostate cancer, due to overt hypogonadism, but there has been little evaluation of the skeletal effects of chemotherapy alone in adults. This study assesses the extent of bone loss due to previous chemotherapy in men. EXPERIMENTAL DESIGN The bone mineral density (BMD) of men who had received previously chemotherapy with curative intent for lymphoma or testicular cancers was compared with that of an age-matched population of men from a cancer control population that had not received chemotherapy. BMD was measured by dual-energy X-ray scanning. Additionally, measurement of sex hormones and the bone turnover markers N-telopeptide fragment of type I collagen and bone-specific alkaline phosphatase were done. All statistical tests were two sided. RESULTS One hundred fifteen chemotherapy-treated patients and 102 cancer controls were recruited. There was no statistical difference in BMD between the chemotherapy and control groups at either spine or hip and the mean BMD values in both groups were no lower than that of a reference population. There were no significant differences in estradiol, luteinizing hormone, and testosterone, but follicle-stimulating hormone values were significantly higher in the chemotherapy group (P=0.011). The mean values of NH2-terminal telopeptide fragment of type I collagen and bone-specific alkaline phosphatase were within the reference ranges. CONCLUSIONS The absence of accelerated bone loss following chemotherapy is reassuring and suggests that standard dose cytotoxic chemotherapy has no lasting clinically important direct effects on bone metabolism.

Abstract
OBJECTIVES To evaluate the frequency and degree of severity of endocrine late effects in patients treated for childhood cancer and to assess the value of the late effects clinic for continued monitoring of these patients. METHOD Data was collected on all patients who attended the late effects clinic at the Royal Children's Hospital (RCH) between 1998-2003. Endocrine function was assessed by clinical and biochemical evaluation at the time of presentation and at ongoing intervals of 3-12 months as clinically indicated. RESULTS A total of 249 children attended the late effects clinic. Two hundred and thirty five endocrine diagnoses were made in 155 (62%) patients, of whom 63 patients had multiple endocrinopathies. CONCLUSION Our audit supports the need for ongoing prospective surveillance in survivors of childhood cancer. Appropriate and timely interventions in such patients can help to reduce morbidity and improve quality of life.

Abstract
The purpose of the current study was to test the hypothesis that an altered fat distribution in elderly healthy subjects and in patients with type-2 diabetes contributes to high circulating levels of interleukin (IL)-6 and tumor necrotic factor (TNF)-alpha, which secondly is related to lower muscle mass. Twenty young controls, (20-35 yr), 20 healthy elderly subjects (65-80 yr) and 16 elderly patients with type 2 diabetes (65-80 yr) were included in a cross sectional study. Plasma levels of TNF-alpha and IL-6 were measured after an overnight fast. Dual-energy X-ray absorptiometry and total body potassium counting measured truncal fat, appendicular skeletal muscle mass (ASM) and body cell mass (BCM), respectively. TNF-alpha, IL-6 and the relative truncal fat mass were higher in elderly compared with young controls. ASM was lower in diabetic men than in young controls and BCM was lower in elderly men compared with young men. TNF-alpha and IL-6 were correlated with the absolute as well as the relative truncal fat mass in univariate regression analyses. Similar results were found in multivariate linear regression analyses after adjusting for the effect of age and gender. TNF-alpha was related to lower ASM and BCM in elderly men both in a univariate regression analysis and a multivariate regression analysis. In conclusion, high plasma levels of TNF-alpha and IL-6 in elderly healthy people and in patients with type 2 diabetes are associated with increased truncal fat mass, suggesting that cytokines are partly derived from this adipose tissue bed. Furthermore, TNF-alpha was related to lower ASM and BCM, suggesting that TNF-alpha contributes to sarcopenia in ageing.

Abstract
Treatment with cytotoxic chemotherapy and radiotherapy is associated with significant gonadal damage in men. Alkylating agents, such as cyclophosphamide and procarbazine, are the most common agents implicated. The vast majority of men receiving procarbazine-containing regimens for the treatment of lymphomas are rendered permanently infertile. Treatment with adriamycin, bleomycin, vinblastine and dacarbazine (ABVD) appears to have a significant advantage in terms of testicular function, with a return to normal fertility in the vast majority of patients. Cisplatin-based chemotherapy for testicular cancer results in temporary azoospermia in most men with a recovery of spermatogenesis in about 50% after 2 years and 80% after 5 years. There is also evidence of chemotherapy-induced Leydig cell impairment in a proportion of these men, although this appears to be of no clinical significance in the majority of patients. The germinal epithelium is very sensitive to radiation-induced damage with changes to spermatogonia following as little as 0.1 Gy, and permanent infertility after fractionated doses of 2 Gy and above, whereas clinically significant Leydig cell impairment occurs rarely with doses of less than 20 Gy.

Abstract
Treatment with cytotoxic chemotherapy and radiotherapy is associated with significant gonadal damage in men and women. The likelihood of gonadal failure following cytotoxic chemotherapy is dependent on the drug and dose, and in women there is also an effect of age at treatment. Irradiation of the testes or ovaries, either directly or indirectly, is also a significant cause of gonadal dysfunction, and the potential to recover from damage is clearly related to the radiation dose received. Several methods of preserving gonadal function during potentially sterilizing treatment have been considered. At present, sperm banking remains the only proven method in men, although hormonal manipulation to enhance recovery of spermatogenesis and cryopreservation of testicular germ cells are possibilities for the future. Transposition of the ovaries to allow better shielding during radiotherapy is of use in some women, and the prospect of cryopreservation and reimplanation of ovarian tissue appears to be promising.

Abstract
OBJECTIVE Testosterone deficiency is associated with significant morbidity, and androgen replacement in overt hypogonadism is clearly beneficial. However, there are few data concerning the response to therapy in young men with mild testosterone deficiency. DESIGN AND PATIENTS We have identified a cohort of 35 men, mean age 40.9 years, with mild Leydig cell dysfunction, defined by a raised LH level (LH >or= 8 IU/l) and a testosterone level in the lower half of the normal range or frankly subnormal (testosterone < 20 nmol/l), following treatment with cytotoxic chemotherapy for malignancy. Patients were assigned randomly to 12 months treatment with transdermal testosterone (n = 16) (Andropatch 2.5 mg patches, 1-2 patches per day) or placebo patches (n = 19) in a single blinded manner. MEASUREMENTS Measurements of bone mineral density (BMD) and body composition were performed at baseline, 6 months and 12 months using single and dual energy X-ray absorptiometry (SXA, DXA). In addition, spinal BMD was assessed at baseline and 12 months by quantitative CT (QCT). Subjects were reviewed at 3-monthly intervals; at each visit blood was taken for measurement of testosterone, SHBG, LH, FSH, oestradiol, lipids and IGF-1 and patients completed three questionnaires which assessed energy levels, mood and sexual function. RESULTS Total testosterone and calculated free testosterone increased significantly in the testosterone-treated group compared with the placebo-treated group (13.3 nmol/l and 342.9 pmol/l at baseline compared with 17.3 nmol/l and 454.8 pmol/l during the study period in the testosterone-treated group; P = 0.05 and P = 0.02, respectively). LH was suppressed into the normal range in 15 of the 16 testosterone-treated men and mean LH significantly reduced from 11.1 IU/l at baseline to 6.8 IU/l during the study. There was no significant change in BMD at the hip, spine or forearm and no change in fat or lean body mass. There was a significant reduction in physical fatigue in the testosterone-treated group compared with the placebo-treated group (P = 0.008) and a borderline improvement in activity score (P = 0.05). There were no significant effects of treatment on mood or sexual function. Neither oestradiol nor IGF-1 levels differed between the two groups during the study. There was no significant change in mean total cholesterol, HDL cholesterol or triglyceride levels, but there was a small, but significant reduction in LDL cholesterol levels in the testosterone-treated group compared with the placebo group (P = 0.02). CONCLUSIONS These results suggest that testosterone therapy in young men with raised LH levels and low/normal testosterone levels does not result in significant changes in BMD, body composition, lipids or quality of life, apart from a reduction in physical fatigue and a small reduction in LDL cholesterol. This implies that mild hypogonadism defined on this basis is not of clinical importance in the majority of men, and that androgen replacement cannot be recommended for routine use in these patients.

Abstract
Abstract
This review focuses on the different treatment options available for the treatment of Hodgkin's disease, with an emphasis on the importance of the long-term sequelae of these therapies.
In Section I, Dr. Linch reviews the current status of Hodgkin's disease treatment. Survival rates have improved over the last three decades due both to better initial therapies and associated supportive care and to the success of salvage therapy. Unlike most other malignancies, a similar survival endpoint can be achieved by different means, e.g., intensive initial therapy resulting in a low relapse rate or less intensive initial therapy and more reliance on salvage therapy. Overall survival has thus become a difficult end-point for clinical trials of primary therapy, and the value of disease-free survival as an end-point can also be questioned. Quality-of-life issues are to the fore of clinical decision and include the psychological trauma of relapse and fertility status. Patient choice is increasingly important. The high level of success in treating Hodgkin's disease also means that attention must be focused on the very long term results and in this context the occurrence of second malignancies is a major issue.
In Section II, Dr. Gosden with Dr. Tulandi and Dr. Tan review the risks of infertility following radio-therapy and chemotherapy and address the actions that can be taken to overcome this problem, particularly for females and prepubertal boys and girls. Particular attention is paid to the recent developments in ovarian cryopreservation and harvesting immature germ cells.
In Section III, Dr. Hancock gives a comprehensive update of the incidence of secondary acute leukemia, non-Hodgkin's lymphoma and solid tumors in a large population of patients treated for Hodgkin's disease. The roles of radiotherapy, chemotherapy and combined modality treatment as risk factors contributing to the development of these secondary malignancies are reviewed. The importance of efforts to prevent late-occurring solid tumors such as lung cancer through smoking cessation programs and early detection by screening for cancers of the breast, thyroid and skin are emphasized.
