RESUMO

We studied the fecundity of 174 successive ALL (1987-2007) in females of the Childhood Cancer Registry of the Rhône-Alpes Region (ARCERRA) with a median age at follow-up of 25.6 years (18.0-37.4). We distinguished five treatment groups: Group Ia, chemotherapy only (n = 130); Ib, chemotherapy with cranial radiotherapy (n = 10); II, TBI conditioning allograft (n = 27); III, chemotherapy conditioning allograft (n = 4); IV, TBI conditioning autograft (n = 3). Twenty-three women had their first child at the mean age of 25.8 ±3.0 years, i.e., 2.0 ±2.9 years earlier than the general population of the Rhône-Alpes region (P = 0.003). The standardized fertility ratio (SFR), expressed as the number of actual births observed (O) to the number that would be expected in women of the same age in the general population (E) (SFR = O/E) was decreased for Group Ia (0.62; 95%CI, 0.52-0.74) and collapsed in Group II (0.17; 0.11-0.25). In univariate analysis, TBI (P = 0.013) and alkylating agents (P = 0.01) were negatively correlated with fecundity, but not with the age at diagnosis or the anthracyclines doses. In multivariate analysis including TBI and alkylating agents, we still found a negative correlation between TBI (P = 0.035), as well as alkylating agents (P = 0.028), and fecundity. More precisely, fecundity was negatively correlated with cumulative cyclophosphamide equivalent dose (P = 0.001), with a fecundity decreased for ≥1g/m(2), but without any dose effect; results not found in the Group Ia. Age at first child seems younger but the young median age of the cohort not allows concluding; fecundity is collapsed after fractionated total body irradiation and decreased after chemotherapy without any demonstrable cause. A delay of fertility is not excluded.

RESUMO

Laparoscopy in adrenocortical carcinoma is controversial due to high risk of local recurrence in case of per-operative spillage. We wanted to report the case of a successful laparoscopic transperitoneal adrenalectomy performed in a 3-year-old girl presenting a 5.5-cm adrenocortical carcinoma.

RESUMO

Impaired linear growth has been reported in patients treated during childhood with allogeneic stem cell transplantation and fractionated total body irradiation (fTBI). The objective of this study was to determine the final height and body mass index (BMI) achieved. Forty-nine patients with leukemia were included and surveyed for more than 5 years. Median age at follow-up was 24.3 years (range, 18.9-35.8) and median follow-up time from allograft was 14.4 years (range, 4.5-21.9). Mean height standard deviation score (s.d.s.) at final examination (-1.1 ± 1.3,) was significantly lower than at fTBI (0.3 ± 1.2; P = .001). Final height s.d.s. was significantly correlated with age at diagnosis, age at fTBI, and target height (P = .001; P < .001; P < .001, respectively). Final height was significantly lower in children transplanted before age 5 (P = .006). Growth hormone treatment (n = 6) had only a modest effect on growth velocity. Mean BMI at follow-up was normal at 19.6 kg/m(2) for boys and 21.2 for girls, but with a significant decrease since allograft only for boys (-1.2 ± 1.5 s.d.s.) (P = .003). In conclusion, final height is decreased; BMI is normal but decreased from fTBI in boys.

RESUMO

BACKGROUND: Somatotropinoma, a pituitary adenoma characterised by excessive production of growth hormone (GH), is extremely rare in childhood. A genetic defect is evident in some cases; known genetic changes include: multiple endocrine neoplasia type 1 (MEN1); Carney complex; McCune-Albright syndrome; and, more recently identified, aryl hydrocarbon receptor-interacting protein (AIP). We describe seven children with somatotropinoma with a special focus on the differences between genetic and sporadic forms. METHODS: Seven children who presented in our regional network between 1992 and 2008 were included in this retrospective analysis. First-type therapy was somatostatin (SMS) analogues or transsphenoidal surgery. Control was defined as when insulin-like growth factor-1 (IGF-1) levels were within the normal range for the patient's age at 6 months after therapy, associated with decreasing tumour volume. RESULTS: Patients were aged 5-17 years and the majority (n = 6) were male. Four patients had an identified genetic mutation (McCune-Albright syndrome: n = 1; MEN1: n = 1; AIP: n = 2); the remaining three cases were sporadic. Accelerated growth rate was reported as the first clinical sign in four patients. Five patients presented with macroadenoma; invasion was noted in four of them (sporadic: n = 1; genetic: n = 3). Six patients were treated with SMS analogues; normalisation of IGF-1 occurred in one patient who had a sporadic intrasellar macroadenoma. Multiple types of therapy were necessary in all patients with an identified genetic mutation (4 types: n = 1; 3 types: n = 2; 2 types: n = 1), whereas two of the three patients with sporadic somatotropinoma required only one type of therapy. CONCLUSIONS: This is the first series that analyzes the therapeutic response of somatotropinoma in paediatric patients with identified genetic defects. We found that, in children, genetic somatotropinomas are more invasive than sporadic somatotropinomas. Furthermore, SMS analogues appear to be less effective for treating genetic somatotropinoma than sporadic somatotropinoma.

RESUMO

A 10-month-old male presented with sudden growth failure and cachexia. MRI showed a chiasma of the hypothalamic mass. Biopsy was avoided due to operative risks. Three cycles of chemotherapy were given, resulting in stable disease on MRI, but growth failure despite attempts at enteral feeding. Surgical biopsy was then performed. A 30% tumor reduction was observed on post-operative imaging. Pathological examination revealed a pilocytic astrocytoma. After surgery, the child gained weight and his growth curve returned to normal. Enteral feeding was discontinued. After 4-year of follow-up, neurological development remains normal, with no residual or endocrine abnormalities.
