- Due to uncertainties regarding clinically meaningful gains from adjuvant chemotherapy after colorectal cancer surgery, several Nordic Groups in the early 1990s initiated randomised trials to prove or reject such gains. This report gives the joint analyses after a minimum 5-year follow-up. Between October 1991 and December 1997, 2 224 patients under 76 years of age with colorectal cancer stages II and III were randomised to surgery alone (n = 1 121) or adjuvant chemotherapy (n = 1 103) which varied between trials (5FU/levamisole for 12 months, n = 444; 5FU/leucovorin for 4-5 months according to either a modified Mayo Clinic schedule (n = 262) or the Nordic schedule (n = 397). Some centres also randomised patients treated with 5FU/leucovorin to+/-levamisole). A total of 812 patients had colon cancer stage II, 708 colon cancer stage III, 323 rectal cancer stage II and 368 rectal cancer stage III. All analyses were according to intention-to-treat. No statistically significant difference in overall survival, stratified for country or region, could be found in any group of patients according to stage or site. In colon cancer stage III, an absolute difference of 7% (p = 0.15), favouring chemotherapy, was seen. The present analyses corroborate a small but clinically meaningful survival gain from adjuvant chemotherapy in colon cancer stage III, but not in the other presentations.

- AIM: To study the influence of growth hormone (GH) treatment on the initiation and progression of puberty in short children. METHODS: This prospective, randomized, controlled study included 124 short children (33 girls) who received GH treatment (Genotropin(R); Pfizer Inc.) from a mean age of 11 years until near adult height [intent-to-treat (ITT) population]. Children were randomized into three groups: controls (n = 33), GH 33 mug/kg/day (n = 34) or GH 67 mug/kg/day (n = 57). Prepubertal children at study start constituted the per-protocol (PP) population (n = 101). Auxological measurements were made and puberty was staged every 3 months. Serum sex-steroid concentrations were assessed every 6 months. RESULTS: No significant differences were found between the groups, of both PP and ITT populations, in time elapsed from start of treatment until either onset of puberty, age at start of puberty or age at final pubertal maturation in either sex. In the ITT population, pubertal duration was significantly longer in GH-treated girls, and maximum mean testicular volume was significantly greater in GH-treated boys than controls, but there were no differences in testosterone levels between the groups. CONCLUSION: GH treatment did not influence age at onset of puberty and did not accelerate pubertal development. In boys, GH treatment appeared to increase testicular volume.

- Adiponectin is secreted by adipose tissue and circulates in human plasma at high levels. Decreased adiponectin levels are associated with insulin resistance and obesity. The aim of this study was to investigate whether changes in serum adiponectin levels are related to the growth response, insulin levels and insulin resistance during growth hormone (GH) treatment.

- Background In addition to stimulating linear growth in children, growth hormone (GH) influences metabolism and body composition. These effects should be considered when individualizing GH treatment as dose-dependent changes in metabolic markers have been reported. Hypothesis: There are different dose-dependent thresholds for metabolic effects in response to GH treatment. Method A randomized, prospective, multicentre trial TRN 98-0198-003 was performed for a 2-year catch-up growth period, with two treatment regimens (a) individualized GH dose including six different dose groups ranging from 17--100 mug/kg/day (n=87) and (b) fixed GH dose of 43 mug/kg/day (n=41). The individualized GH dose group was used for finding dose--response effects, where the effective GH dose (ED 50%) required to achieve 50% Delta effect was calculated with piecewise linear regressions. Results Different thresholds for the GH dose were found for the metabolic effects. The GH dose to achieve half of a given effect (ED 50%, with 90% confidence interval) was calculated as 33(+/-24.4) mug/kg/day for [increment] left ventricular diastolic diameter (cm), 39(+/-24.5) mug/kg/day for [increment] alkaline phosphatase (mukat/L), 47(+/-43.5) mug/kg/day for [increment] lean soft tissue (SDS), 48(+/-35.7) mug/kg/day for [increment] insulin (mU/L), 51(+/-47.6) mug/kg/day for [increment] height (SDS), and 57(+/-52.7) mug/kg/day for [increment] insulin-like growth factor I (IGF-I) SDS. Even though lipolysis was seen in all subjects, there was no dose--response effect for Delta fat mass (SDS) or Delta leptin ng/ml in the dose range studied. None of the metabolic effects presented here were related to the dose selection procedure in the trial. Conclusions Dose-dependent thresholds were observed for different GH effects, with cardiac tissue being the most responsive and level of IGF-I the least responsive. The level of insulin was more responsive than that of IGF-I, with the threshold effect for height in the interval between.

- Context: Few studies have evaluated the metabolic outcomes of growth hormone (GH) treatment in idiopathic short stature (ISS). Moreover, children with ISS appear to need higher GH doses than children with GH deficiency (GHD) to achieve the same amount of growth, and may therefore be at increased risk of adverse events during treatment. The individualized approach using prediction models for estimation of GH responsiveness, on the other hand, has the advantage of narrowing the range of growth response, avoiding too low or high GH doses. Design: Short prepubertal children with either isolated GHD (39) or ISS (89) participated in a 2-year randomized trial of either individualized GH treatment with six different GH doses (range, 17-100 mug/kg/day) or a standard dose (43 mug/kg/day). Objective: To evaluate if individualized GH treatment reduced the variance of the metabolic measures as shown for growth response, and to compare changes in metabolic variables in children with ISS and GHD. Hypothesis: Individualized GH dose reduces the range of metabolic outcomes, and metabolic outcomes are similar in children with ISS and GHD. Results: We observed a narrower variation for fasting insulin (-34.2%) and for HOMA (-38.9%) after two years of individualized GH treatment in comparison to standard GH dose treatment. Similar metabolic changes were seen in ISS and GHD. Delta (Delta) height SDS correlated with Deltainsulin-like growth factor I (IGF-I), Deltaleptin and Deltabody composition. Principal component analysis identified an anabolic and a lipolytic component. Anabolic variables [Deltalean body mass (LBM) SDS and DeltaIGF-I SDS] clustered together and correlated strongly with Deltaheight SDS and GH dose, whereas lipolytic variables [Deltafat mass SDS and Deltaleptin] were clustered separately from anabolic variables. Regression analysis showed GH dose-dependency in ISS, and to a lesser degree in GHD, for DeltaLBM SDS and Deltaheight SDS, but not for changes in fat mass. Conclusions: Individualized GH dosing during catch-up growth reduces the variance in insulin and HOMA and results in equal metabolic responses irrespective of the diagnosis of GHD or ISS.

- Background: To compare irinotecan with the Nordic 5-fluorouracil (5-FU) and folinic acid (FA) bolus schedule [irinotecan 180 mg/m2 on day 1, 5-FU 500 mg/m2 and FA 60 mg/m2 on day 1 and 2 (FLIRI)] or the Lv5FU2 schedule [irinotecan 180 mg/m2 on day 1, FA 200 mg/m2, 5-FU bolus 400 mg/m2 and infused 5-FU 600 mg/m2 on day 1 and 2 (Lv5FU2-IRI)] due to uncertainties about how to administrate 5-FU with irinotecan. Patients and methods: Patients (n = 567) with metastatic colorectal cancer were randomly assigned to receive FLIRI or Lv5FU2-IRI. Primary end point was progression-free survival (PFS). Results: Patient characteristics were well balanced. PFS did not differ between groups (median 9 months, P = 0.22). Overall survival (OS) was also similar (median 19 months, P = 0.9). Fewer objective responses were seen in the FLIRI group (35% versus 49%, P = 0.001) but the metastatic resection rate did not differ (4% versus 6%, P = 0.3). Grade 3/4 neutropenia (11% versus 5%, P = 0.01) and grade 2 alopecia (18% versus 9%, P = 0.002) were more common in the FLIRI group. The 60-day mortality was 2.4% versus 2.1%. Conclusions: Irinotecan with the bolus Nordic schedule (FLIRI) is a convenient treatment with PFS and OS comparable to irinotecan with the Lv5FU2 schedule. Neutropenia and alopecia are more prevalent, but both regimens are equally well tolerated. © The Author 2008.

- Objective: The primary aim of the study was to evaluate d3-GHR as a possible cause of increased GH sensitivity in children with delayed infancy-childhood transition (DICT). The secondary aim was to investigate the impact of the GHR exon 3 deleted/full-length (d3/f1) polymorphism on GH treatment response in prepubertal children classified as having idiopathic short stature (ISS). Design: Study subjects included 167 prepubescent longitudinally followed children classified as having ISS. Children were randomized to standard-dose GH treatment (33 mu g kg(-1) day(-1)), to double-dose treatment (67 mu g kg(-1) day(-1)), or to an untreated control group. Growth and metabolic outcome were evaluated at birth (n = 166), after one year of treatment (n = 59) and at adult height (n = 145). Genotyping of the GHR d3/f1 polymorphism was performed using TaqMan SNP genotyping of tagSNP rs6873545. Results: Birth and early growth data did not reach the predetermined level of statistical significance for difference between genotypes. Growth and IGF-1 response after one year of GH treatment did not differ between genotypes. IGFBP-3(SDS) was higher in untreated d3-GHR carriers than in untreated fl/fl individuals, whereas there was insufficient evidence for higher IGFBP-3(SDS) in treated d3-GHR carriers. Genotype did not explain the growth response to treatment, and no differences in height(SDS), height gain, or difference in height to midparental height(SDS) between genotype groups were found at adult height. Conclusion: The common GHR d3/fl polymorphism is probably not a cause of DICT in children with ISS, and our results do not suggest that the d3-GHR genotype is associated with increased sensitivity to GH in children with ISS.

- AimTo establish normal reference values for penile size in Nigerian newborn boys and to compare those values with standards from other populations. MethodsA total number of 261 healthy newborn boys delivered at gestational ages of 28weeks or more were enrolled in the study. Penile lengths and widths were measured within 72h of birth. ResultsThe mean (SD) penile length in the 261 Nigerian males studied was 3.4 +/- 0.48cm, while the mean mid-shaft diameter was 1.2 +/- 0.14cm. Compared with data from other populations, Nigerian newborn boys had similar penile sizes to those reported for US Caucasian boys (mean 3.4cm), but significantly greater penile sizes than those reported for boys from China and Hong Kong (mean 3.0 and 3.1cm, respectively; both p<0.001). There was a slight, but significant, difference in size between Nigerian and Malaysian boys, with Malaysian boys having greater penile sizes (mean 3.5cm; p<0.05). ConclusionA Nigerian newborn with a penile length of <2.39cm can be considered to have a micropenis.
