Abstract
The most common malignancies in childhood are leukaemias, brain tumours, lymphomas, neuroblastomas, soft tissue sarcomas and kidney tumours. At present, about 80% of childhood cancers can be treated successfully, which has significantly increased long-term survival. Concomitantly, adult gonadal function in childhood cancer survivors has become a concern. However, the immediate effect of cancer and its management on the reproductive axis function has received less attention. We conducted a review of the effects of malignancies and their treatments on the gonadal axis during childhood and adolescence. Some results are controversial, probably because the analyses do not distinguish between the malignancy types, their treatments and/or the age at treatment. However, there is agreement that cancer can partially affect gonadal function before treatment, as revealed by low circulating levels of inhibin B and anti-Müllerian hormone. Subsequently, chemotherapy transiently impairs the somatic component of the gonads (i.e. testicular Sertoli cells and ovarian granulosa cells) with normalization after treatment ends. The impact of chemotherapy may persist through adulthood after more intensive chemotherapy regimens, radiotherapy and conditioning for haematopoietic stem cell transplantation, when there is a severe impairment of the somatic component of the gonads or of the stem germ cells.

Abstract
Survival rates of childhood cancer have improved markedly, and today more than 80 % of those diagnosed with a pediatric malignancy will become 5-year survivors. Nevertheless, survivors exposed to cranial radiotherapy (CRT) are at particularly high risk for long-term morbidity, such as endocrine insufficiencies, metabolic complications, and cardiovascular morbidity. Deficiencies of one or more anterior pituitary hormones have been described following therapeutic CRT for primary brain tumors, nasopharyngeal tumors, and following prophylactic CRT for childhood acute lymphoblastic leukemia (ALL). Studies have consistently shown a strong correlation between the total radiation dose and the development of pituitary deficits. Further, age at treatment and also time since treatment has strong implications on pituitary hormone deficiencies. There is evidence that the hypothalamus is more radiosensitive than the pituitary and is damaged by lower doses of CRT. With doses of CRT <50 Gy, the primary site of radiation damage is the hypothalamus and this usually causes isolated GH deficiency (GHD). Higher doses (>50 Gy) may produce direct anterior pituitary damage, which contributes to multiple pituitary deficiencies. The large group of ALL survivors treated with CRT in the 70–80-ties has now reached adulthood, and these survivors were treated mainly with 24 Gy, and the vast majority of these patients suffer from GHD. Further, after long-term follow-up, insufficiencies in prolactin (PRL) and thyroid stimulating hormone (TSH) have also been reported and a proportion of these patients were also adrenocoticotrophic hormone (ACTH) deficient. CRT to the hypothalamus causes neuroendocrine dysfunction, which means that the choice of GH test is crucial for the diagnosis of GHD.

Abstract
The past 30 years have seen a great improvement in survival of children and young adults treated for cancer. Cancer treatment can put patients at risk of health problems that can develop many years later, most commonly affecting the endocrine system. Patients treated with cranial radiotherapy often develop dysfunction of the hypothalamic-pituitary axis. A characteristic pattern of hormone deficiencies develops over several years. Growth hormone is disrupted most often, followed by gonadal, adrenal, and thyroid hormones, leading to abnormal growth and puberty in children, and affecting general wellbeing and fertility in adults. The severity and rate of development of hypopituitarism is determined by the dose of radiotherapy delivered to the hypothalamic-pituitary axis. Individual growth hormone deficiencies can develop after a dose as low as 10 Gy, whereas multiple hormone deficiencies are common after 60 Gy. New techniques in radiotherapy aim to reduce the effect on the hypothalamic-pituitary axis by minimising the dose received. Patients taking cytotoxic drugs do not often develop overt hypopituitarism, although the effect of radiotherapy might be enhanced. The exception is adrenal insufficiency caused by glucocorticosteroids which, although transient, can be life-threatening. New biological drugs to treat cancer can cause autoimmune hypophysitis and hypopituitarism; therefore, oncologists and endocrinologists should be vigilant and work together to optimise patient outcomes.

Abstract
Purpose We report a very rare case showing menstrual restoration in severe pan-hypopituitarism many years after cranial irradiation for suprasellar germinoma. Case A 30-year-old, almost primarily amenorrheic woman with severe panhypopituitarism presented with cyclic genital bleeding for the previous five months. She had menstruated once, when she was 13 years old. When she was 14 years old, she was diagnosed with a suprasellar germinoma measuring 10 mm in diameter, which led to diabetes insipidus. Cranial irradiation with a total dose of 24 Gy and chemotherapy resulted in complete tumor remission. She developed severe hypopituitarism [luteinizing hormone (LH) = 0.4 mIU/mL, follicle-stimulating hormone (FSH) = 1.7 mIU/mL, and serum estradiol (E2) level < 10 pg/mL]. She had received multiple hormone replacement therapies for many years. When she was 29 years old, she expressed a desire to become pregnant. Serum gonadotropin and E2 levels increased (LH = 5.8 mIU/mL, FSH = 5.9 mIU/mL, and E2 = 58 pg/mL). She conceived with clomiphene therapy, and then delivered a healthy baby. Eight months after parturition, her basal body temperature and serum progesterone levels indicated recovery of ovulatory cycles. Ten months after parturition, she also spontaneously conceived. Conclusion Menstrual restoration is very rare in severe panhypopituitarism after cranial irradiation. A relatively low dose of irradiation and small tumor size may have contributed to the recovery of menstruation in our patient.

Abstract
PURPOSE OF REVIEW Progressive and irreversible neuro-endocrine dysfunction following radiation-induced damage to the hypothalamic-pituitary (h-p) axis is the most common complication in cancer survivors with a history of cranial radiotherapy involving the h-p axis and in patients with a history of conventional or stereotactic pituitary radiotherapy for pituitary tumours. This review examines the controversy about the site and pathophysiology of radiation damage while providing an epidemiological perspective on the frequency and pattern of radiation-induced hypopituitarism. RECENT FINDINGS Contrary to the previously held belief that h-p axis irradiation with doses less than 40 Gy result in a predominant hypothalamic damage with time-dependent secondary pituitary atrophy, recent evidence in survivors of nonpituitary brain tumours suggests that cranial radiation causes direct pituitary damage with compensatory increase in hypothalamic release activity. Sparing the hypothalamus from significant irradiation with sterteotactic radiotherapy for pituitary tumours does not appear to reduce the long-term risk of hypopituitarism. SUMMARY Radiation-induced h-p dysfunction may occur in up to 80% of patients followed long term and is often associated with an adverse impact on growth, body image, skeletal health, fertility, sexual function and physical and psychological health. A detailed understanding of pathophysiological and epidemiological aspects of radiation-induced h-p axis dysfunction is important to provide targeted and reliable long-term surveillance to those at risk so that timely diagnosis and hormone-replacement therapy can be provided.

Abstract
UNLABELLED With the improved survival rate of childhood and young adult cancer patients, the long-term sequelae of the treatments used are increasingly important. In this review, current knowledge of the gonadotoxicity of commonly employed chemotherapeutic agents and radiotherapy regimens is examined. Differences between the effect of "high-risk" and "low-risk" agents are discussed. Tailoring treatment to suit the individual and counseling patients regarding reduced fertility have resulted in the best practice. TARGET AUDIENCE Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES After completing this CME activity, physicians should be better able to evaluate and use appropriate methods to estimate ovarian reserve, assess the risk of infertility caused by commonly used cytotoxic chemotherapy regimens and radiation, and counsel patients regarding the gonadotoxic effects of cancer treatment.

Abstract
In the present study the authors evaluated therapy-related long-term adverse effects and physical activity in a cohort of long-term survivors of childhood acute lymphoblastic leukemia (ALL), diagnosed in their center between March 1991 and August 2000, treated according to the AIEOP (Associazione Italiana di Ematologia e Oncologia Pediatrica) ALL 91 or 95 study protocol and regularly seen in the authors' long-term follow-up unit. The authors analyzed the long-term sequelae of major body systems in this cohort of subjects and administered an "ad hoc" questionnaire concerning sport. The authors found that 70 patients out of 102 (68.5%) showed no late effects, 10% presented only instrumental or neuropsychological test abnormalities, and 21.5% had 1 or more clinical late sequelae. None of the evidenced late effects represented a contraindication to do physical activity. Sixty-one percent of survivors do physical activity, most of them regularly. Sixty-one percent of males and 18.5% of females (P < .005) do competitive sport (sports rates are similar to those of the general age-matched population). Nearly all subjects spontaneously choose to do sport and think physical exercise is an important and useful resource for their health. The authors conclude that the more recent therapy regimens for leukemia treatment, excluding bone marrow transplantation, do not seem to cause such late effects as to prevent survivors from doing sport. Therefore, in the care of ALL survivors, physical activity is not only not contraindicated, but should also be promoted as much as possible. The development of specific educational programs is warranted as part of the care of cancer survivors.

Abstract
The increasing use of radiation treatment for head and neck cancers and other tumors, including pituitary adenomas, from the mid-20th Century onwards led to the recognition that pituitary function may be affected - often leading to some degree of pituitary insufficiency. Our knowledge is mostly based on observational or retrospective rather than randomized prospective studies. The various axes may be impacted at the hypothalamic or pituitary levels, or both. Some axes - the somatotropic and gonadotropic - appear to be especially vulnerable to radiation damage and may be affected quite early, whereas posterior pituitary function is rarely affected. Increased use of stereotactic radiosurgery, which focuses the radiation dose on the abnormal tissue, may be expected to reduce the impact on normal pituitary function, but such studies that are available are, as yet, relatively short term. Prospective studies of the effect of stereotactic radiosurgery on pituitary function would be valuable.

Abstract
The treatment and survival outcome of acute leukemia in women is generally similar to that of men. However, acute leukemia in women poses additional challenges in clinical practice. In addition to important precautions during therapy, such as prevention of abnormal uterine bleeding in premenopausal women and therapy during pregnancy, women who are survivors of acute leukemia face unique and potentially long-term health-related problems. In this review, we address the aforementioned issues, as well as the various health and psychosocial challenges faced by women who survive childhood leukemia during their path to adulthood. Finally, we address the issue of therapy-related acute leukemia in the category of women who are survivors of breast and ovarian cancer.

Abstract
BACKGROUND Children who receive high-dose radiotherapy to the hypothalamic-pituitary (H-P) axis may be at risk for both early and late puberty. To the authors' knowledge, data regarding the risk of altered timing of menarche after higher dose radiotherapy (RT), as used in the treatment of central nervous system (CNS) tumors, are limited. METHODS The authors evaluated 235 female survivors of CNS tumors, diagnosed between 1970 and 1986, and >1000 sibling controls who were participants in the Childhood Cancer Survivor Study, and provided self-reported data concerning age at menarche. RESULTS Survivors of CNS tumors were more likely to have onset of menarche before age 10 years compared with their siblings (11.9% vs 1.0%) (odds ratio [OR], 14.1; 95% confidence interval [95% CI], 7.0-30.9). Of the 138 survivors who received RT to the H-P axis, 20 (14.5%) had onset of menarche before age 10 years, compared with 4.3% of those who did not receive RT (OR, 3.8; 95% CI, 1.2-16.5). Age <or=4 years at the time of diagnosis was associated with an increased risk (OR, 4.0; 95% CI, 1.7-10.0) of early menarche. In addition, survivors of CNS tumors were more likely than siblings to have onset of menarche after age 16 years (10.6% vs 1.9%) (OR, 6.6; 95% CI, 3.4-11.4). Doses of RT to the H-P axis >50 gray OR, 9.0; 95% CI, 2.3-59.5) and spinal RT conferred an increased risk of late menarche, as did older age (>10 years) at the time of diagnosis (OR, 3.0; 95% CI, 1.3-7.0). CONCLUSIONS Survivors of CNS tumors are at a significantly increased risk of both early and late menarche associated with RT exposure and age at treatment.

Abstract
Deficiencies in anterior pituitary hormones secretion ranging from subtle to complete occur following radiation damage to the hypothalamic-pituitary (h-p) axis, the severity and frequency of which correlate with the total radiation dose delivered to the h-p axis and the length of follow up. Selective radiosensitivity of the neuroendocrine axes, with the GH axis being the most vulnerable, accounts for the high frequency of GH deficiency, which usually occurs in isolation following irradiation of the h-p axis with doses less than 30 Gy. With higher radiation doses (30-50 Gy), however, the frequency of GH insufficiency substantially increases and can be as high as 50-100%. Compensatory hyperstimulation of a partially damaged h-p axis may restore normality of spontaneous GH secretion in the context of reduced but normal stimulated responses; at its extreme, endogenous hyperstimulation may limit further stimulation by insulin-induced hypoglycaemia resulting in subnormal GH responses despite normality of spontaneous GH secretion in adults. In children, failure of the hyperstimulated partially damaged h-p axis to meet the increased demands for GH during growth and puberty may explain what has previously been described as radiation-induced GH neurosecretory dysfunction and, unlike in adults, the ITT remains the gold standard for assessing h-p functional reserve. Thyroid-stimulating hormone (TSH) and ACTH deficiency occur after intensive irradiation only (>50 Gy) with a long-term cumulative frequency of 3-6%. Abnormalities in gonadotrophin secretion are dose-dependent; precocious puberty can occur after radiation dose less than 30 Gy in girls only, and in both sexes equally with a radiation dose of 30-50 Gy. Gonadotrophin deficiency occurs infrequently and is usually a long-term complication following a minimum radiation dose of 30 Gy. Hyperprolactinemia, due to hypothalamic damage leading to reduced dopamine release, has been described in both sexes and all ages but is mostly seen in young women after intensive irradiation and is usually subclinical. A much higher incidence of gonadotrophin, ACTH and TSH deficiencies (30-60% after 10 years) occur after more intensive irradiation (>60 Gy) used for nasopharyngeal carcinomas and tumors of the skull base, and following conventional irradiation (30-50 Gy) for pituitary tumors. The frequency of hypopituitarism following stereotactic radiotherapy for pituitary tumors is mostly seen after long-term follow up and is similar to that following conventional irradiation. Radiation-induced anterior pituitary hormone deficiencies are irreversible and progressive. Regular testing is mandatory to ensure timely diagnosis and early hormone replacement therapy.

Abstract
The aim of this study was to investigate reproductive history and the prevalence of imminent ovarian failure (IOF) in female childhood cancer survivors. Reproductive history and ovarian function were evaluated by questionnaires (n=124) and by measurement of follicle stimulating hormone (FSH) and oestradiol (E2) levels (n=93). IOF was defined as FSH>10 IU/l or E2>0.28 nmol/l on day 3 of the menstrual cycle, or FSH>12.4 IU/l on day 7 of the pill-free interval. IOF was demonstrated in 22.6% of the participants and correlated with age at diagnosis (P<0.005) and age at study (P=0.036). IOF correlated inversely with methotrexate (P=0.046). The incidence of miscarriages (22.7%) and recurrent miscarriages (7.3%) was increased. The male/female (M/F) ratio of the offspring was decreased. In conclusion, female childhood cancer survivors are at risk for IOF. If pregnant, the risk of (recurrent) miscarriages is increased. The M/F ratio in the offspring is decreased.

Abstract
Radiation-induced damage to the hypothalamic-pituitary (h-p) axis is associated with a wide spectrum of subtle and frank abnormalities in anterior pituitary hormones secretion. The frequency, rapidity of onset and the severity of these abnormalities correlate with the total radiation dose delivered to the h-p axis, as well as the fraction size, younger age at irradiation, prior pituitary compromise by tumour and/or surgery and the length of follow up. Whilst, the hypothalamus is the primary site of radiation-induced damage, secondary pituitary atrophy evolves with time due to impaired secretion of hypothalamic trophic factors and/or time-dependent direct radiation-induced damage. Selective radiosensitivity in the neuroendocrine axes with the GH axis being the most vulnerable to radiation damage accounts for the high frequency of GH deficiency, which usually occurs in isolation following irradiation of the h-p axis with doses less than 30 Gy. With higher radiation doses (30-50 Gy), however, the frequency of GH insufficiency substantially increases and can be as high as 50-100%, and TSH and ACTH deficiency start to occur with a long-term cumulative frequency of 3-6%. Abnormalities in gonadotrophin secretion are dose-dependent; precocious puberty can occur after radiation dose less than 30 Gy in girls only, and in both sexes equally with a radiation dose of 30-50 Gy. Gonadotrophin deficiency occurs infrequently and is usually a long-term complication following a minimum radiation dose of 30 Gy. Hyperprolactinemia, due to hypothalamic damage leading to reduced dopamine release, has been described in both sexes and all ages but is mostly seen in young women after intensive irradiation and is usually subclinical. A much higher incidence of gonadotrophin, ACTH and TSH deficiencies (30-60% after 10 years) occur after more intensive irradiation (>70 Gy) used for nasopharyngeal carcinomas and tumours of the skull base and following conventional irradiation (30-50 Gy) for pituitary tumours. Radiation-induced anterior pituitary hormone deficiencies are irreversible and progressive. Regular testing is mandatory to ensure timely diagnosis and early hormone replacement therapy to improve linear growth and prevent short stature in children cured from cancer, and in adults preserve sexual function, prevent ill health and osteoporosis and improve the quality of life.

Abstract
BACKGROUND Fertility impairments among women treated during childhood for cancer are known to occur after some, but not all, types of anticancer therapy. Although leukemia is the most common cancer of childhood, until now fertility in survivors has not been comprehensively assessed. PROCEDURE We investigated functional impairment of fertility in women who were long-term survivors of acute lymphoblastic leukemia (ALL) with a retrospective cohort study. Proven fertility (defined as ever pregnant) was evaluated by self-report among 182 females treated on protocols of the Children's Cancer Group (age at interview, 22.6 years on average) and 170 controls drawn from among the survivors' female siblings (23.4 years). The interview included psychosocial inventories designed to detect mood problems. RESULTS Significant fertility deficits were noted in female survivors treated with cranial radiotherapy (CRT) at any dose around the time of menarche (relative fertility (RF)) = 0.27, 95% CI = 0.09, 0.82, P = 0.03). Controlling for marital status, mood at interview, and many fertility-related situations did not change the association. CONCLUSION This study provides evidence for fertility deficits after treatment for ALL with CRT, and, in addition, for the first time, suggests that girls treated around the time of menarche are especially at risk. Clinical confirmation of these results is needed. If gonadal damage occurs in women receiving these treatments, their risk for further sequelae, such as osteoporosis and heart disease, may be significantly raised, requiring active management and intervention.

Abstract
Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy, accounting for one-third of all cancers occurring in childhood and adolescents. Over the last 3 decades there has been a marked improvement in survival, with 5-year survival rates approaching 80%. With this improvement in survival, increasing attention is now being focused on issues relating to long-term morbidity and mortality associated with the treatments responsible for that increased survival. Because of the young age of these cancer survivors, and thus the potential longevity, the delayed consequences of therapy may have a significant impact on their lives. Long-term sequelae of treatment, such as impaired intellectual and psychomotor functioning, neuroendocrine abnormalities, impaired reproductive capacity, cardiotoxicity, and second malignant neoplasms, are now being reported with increasing frequency in this growing cohort of survivors and knowledge of the late -effects associated with cancer in children and adolescents continues to increase through ongoing research efforts. However, much of the available information relates to outcomes within the first decade following treatment, although information about the longer term outcomes that may occur later in adulthood is emerging as a result of well-conducted, large cohort studies. Through a multi-disciplinary approach to the diagnosis, treatment, and long-term follow-up of pediatric leukemia patients, we can achieve the goal of cure while minimizing the occurrence of long-term adverse outcomes. This review summarizes some of the well-described long-term consequences of therapy among children and adolescents treated for ALL.

Abstract
Second malignant neoplasms are a serious complication after successful treatment of childhood acute lymphoblastic leukemia (ALL). With improvement in survival, it is important to assess the impact of contemporary risk-based therapies on second neoplasms in ALL survivors. A cohort of 8831 children diagnosed with ALL and enrolled on Children's Cancer Group therapeutic protocols between 1983 and 1995 were observed to determine the incidence of second neoplasms and associated risk factors. The median age at diagnosis of ALL was 4.7 years. The cohort had accrued 54 883 person-years of follow-up. Sixty-three patients developed second neoplasms, including solid, nonhematopoietic tumors (n = 39: brain tumors n = 19, other solid tumors n = 20), myeloid leukemia or myelodysplasia (n = 16), and lymphoma (n = 8). The cumulative incidence of any second neoplasm was 1.18% at 10 years (95% confidence interval, 0.8%-1.5%), representing a 7.2-fold increased risk compared with the general population. The risk was increased significantly for acute myeloid leukemia (standardized incidence ratio [SIR] 52.3), non-Hodgkin lymphoma (SIR 8.3), parotid gland tumors (SIR 33.4), thyroid cancer (SIR 13.3), brain tumors (SIR 10.1), and soft tissue sarcoma (SIR 9.1). Multivariate analysis revealed female sex (relative risk [RR] 1.8), radiation to the craniospinal axis (RR 1.6), and relapse of primary disease (RR 3.5) to be independently associated with increased risk of all second neoplasms. Risk of second neoplasms increased with radiation dose (1800 cGy RR 1.5; 2400 cGy RR 3.9). Actuarial survival at 10 years from diagnosis of second neoplasms was 39%. Follow-up of this large cohort that was treated with contemporary risk-based therapy showed that the incidence of second neoplasms remains low after diagnosis of childhood ALL.

Abstract
The successful treatment of childhood cancer can be associated with impaired gonadal function in adulthood. Chemotherapy and radiotherapy may damage germ-cell spermatogonia, resulting in impaired spermatogenesis or sterility in the male, or may hasten oocyte depletion with truncated fecundity and premature menopause in the female. The only established option in current clinical practice for preserving male fertility is cryopreservation of spermatozoa. The only strategy currently available for preserving female fertility is cryopreservation of embryos. Harvesting and storage of ovarian cortical tissue from girls and young women before potentially gonadotoxic chemotherapy has been available in a number of centres but there have been no live births and the procedure remains experimental. Standards for best practice in the cryopreservation of gonadal tissue, including the criteria for providing a service, patient identification and selection, standard operating procedures and requirements for safe storage, remain to be defined. Recent advances in assisted reproduction may circumvent natural conception barriers and the implications of impaired DNA integrity may be manifest as an increased risk of congenital abnormalities and chromosomal disorders in the offspring. In this chapter we consider the late reproductive sequelae following treatment for childhood cancer and options for fertility preservation.

Abstract
OBJECTIVE As more children survive acute lymphoblastic leukemia (ALL), questions are raised regarding how the disease and its therapy affect their pubertal development. STUDY DESIGN The National Institute of Child Health and Human Development-National Cancer Institute-Children's Cancer Group Leukemia Follow-Up Study used a historical cohort design to investigate menarche in 188 ALL survivors who were premanarchal at diagnosis, aged at least 18 years, at least 2 years after diagnosis, alive, and in remission. Female siblings of ALL survivors (n = 218) served as control subjects. RESULTS Menarche occurred within the normal age range in 92% of survivors and 96% of the control subjects (p = 0.09). Early menarche occurred in four survivors (2%) and three control subjects (1%). Delayed, absent, or medically induced menarche was reported by 12 survivors (6%) and six control subjects (3%). Compared with the control subjects, survivors of ALL who received 1800 cGy cranial radiation before the age of 8 years had significantly earlier menarche, relative hazard (RH) of 2.2 (95% confidence interval: 1.4, 3.4 [p = 0.0003]). Survivors receiving 2400 cGy of craniospinal radiation with or without abdominal radiation had significantly later menarche than the control subjects, RH 0.4 (95% confidence interval: 0.3, 0.7 [p = 0.0002]). CONCLUSIONS In this large cohort of ALL survivors, the risk of disordered menarche was low. However, younger subjects receiving 1800 cGy cranial radiation and those receiving 2400 cGy below the diaphragm required careful monitoring.

Abstract
PURPOSE Although rare, second malignant neoplasms (SMNs) are a devastating consequence of successful treatment of childhood cancer. The 15-year estimated risk of developing a second malignant neoplasm after treatment of childhood acute lymphoblastic leukemia (ALL) is 2.5%. Most of these neoplasms are central nervous system tumors. The risk of secondary acute myeloid leukemia has been negligible in most treatment regimens. Here, we report the first case of a primitive neuroectodermal tumor (PNET) in a patient treated for ALL. PATIENTS AND METHODS A 15.7-year-old girl developed pain in her left leg 7 years after diagnosis of low-risk ALL. Imaging studies revealed lytic lesions in her left proximal tibia and several vertebra as well as metastatic nodules in both lungs. RESULTS Immunocytochemical and molecular analyses led to the diagnosis of PNET. The treatment of this SMN was composed of combination chemotherapy with hematopoietic growth factor support and radiotherapy to the primary lesion and affected spine. The tumor recurred 5 months after the completion of treatment, and the patient is now undergoing salvage therapy composed of chemotherapy and radiotherapy. CONCLUSIONS To our knowledge, this is the first report of PNET as an SMN after successful treatment of ALL.

Abstract
We studied the hormonal pattern of nine patients with acute lymphoblastic leukemia. The patients were treated with standard therapeutic regimens. They were overweight by a mean of 52% at the end of the consolidation treatment, and this persisted after a follow-up of 2 years. The only endocrine alteration observed was a moderate decrease in serum testosterone levels in male patients. The other parameters studied were in the normal range. We conclude that prolonged treatment with high doses of corticosteroids, which have a depressive effect on metabolism, was responsible for the obesity.

Abstract
Ovarian function was assessed in 40 long term survivors who had received standard United Kingdom Acute Lymphoblastic leukaemia (UKALL) protocols and were in first clinical and haematological remission. A menstrual and pregnancy history was taken (median age at assessment: 18.8 (12-34.7) years) and the acquisition of adult secondary sexual characteristics confirmed in each patient. Basal bloods were taken for follicle stimulating hormone (FSH), luteinizing hormone (LH), and serum oestradiol estimations. Serum progesterone concentration was measured in those patients who were in the luteal phase of their menstrual cycle at assessment. In addition, menstrual cycle profiles of salivary progesterone concentrations were derived from daily samples in 12 patients. All patients achieved adult sexual development; median age at menarche was early at 12.4 (9.0-14.6) years and 37 of them have regular menses. Ten patients have had 14 live births, and evidence of ovulation was seen in a further 11 patients assessed in the luteal phase of the menstrual cycle. Four patients had damaged ovaries, two of whom show evidence of ovulation; three of the four received craniospinal irradiation and one received cyclophosphamide as part of her chemotherapy regimen. None of these patients has yet developed total ovarian failure or required sex steroid replacement therapy. The medium term outlook for ovarian function is good for the majority of childhood ALL survivors. The spinal component of craniospinal irradiation is a major risk factor for ovarian damage, and cyclophosphamide may be a contributory factor. A premature menopause remains a possibility if significant follicular depletion has occurred at the time of cytotoxic treatment.

Abstract
Eleven girls treated during childhood for acute leukaemia were followed up during their pubertal development. At each examination weight, height, pubertal stage, FSH, LH, oestradiol, testosterone, androstenedione and dehydroepiandrosterone sulphate levels were evaluated. Clinical and endocrinological studies were performed according to age and pubertal stage and compared to those of healthy girls matched for age and pubertal stage. Results showed that pubertal maturation and gonadal function were not affected by oncotherapy; however menarche was attained earlier. Early menarche was explained by the overweight of treated girls during early puberty. No evidence of early hypothalamic activation was found, but endocrine patterns showed a faster hypothalamopituitary-ovarian axis maturation in patients than controls. Cranial irradiation showed no correlation with pubertal onset and age at which menarche was attained. Adolescent menstrual and endocrine patterns were normal.
