The pathogenesis of testicular germ cell tumours (GCTs) is potentially influenced by high-energy nutrition during infancy. As adult height is a proxy for childhood nutrition, we investigated the role of nutrition in GCT pathogenesis by comparing stature of patients with healthy men. In a matched case-control study, 6415 patients with GCT were compared with healthy army conscripts (1:6 matching modus) with regard to height (cm) and body mass index (BMI; kg/m(2)). Statistical analysis involved tabulation of descriptive height measures and BMI. Conditional logistic regression models were used to quantify the association of GCT with height, with odds ratios (OR) adjusted for BMI. The literature was searched for studies on stature in GCT patients. Body size is significantly associated with risk of GCT, very tall men (>195 cm) having a GCT risk of OR=3.35 (95% confidence intervals (CI): 2.88-3.90; adjusted). Short stature is protective (OR=0.798; 95% CI: 0.68-0.93). Both histologic subgroups are associated with tallness. Of 16 previous reports, 7 were confirmative, 5 had null and 4 equivocal results. The association of stature with GCT risk accords with the nutrition hypothesis of GCT. This study expands the current view of GCT tumorigenesis by suggesting that high-calorie intake in childhood promotes GCT precursors originating in utero.

Objective: To assess the feasibility of 5-Aminolevulinic acid (5ALA) fluorescence-guided resection for recurrent malignant brain tumours. Methods: We conducted a multicentre prospective, single-arm, uncontrolled phase II study. 36 patients with recurrent glioma (WHO grade III/IV) received 5-ALA[for full text, please go to the a.m. URL], 60.

Background: A weekly continuous 24-h infusion therapy with 5-fluorouracil (5-FU) preceded by a 2-h infusion of calcium folinate (CA-FA) was shown to be an effective first- and second-line treatment in advanced metastatic colorectal cancer. Substitution of CA-FA by the new formulation sodium folinate (S-FA) allows the simultaneous i.v. administration of folinic acid with 5-FU in one pump. Patients and Methods: From 1999 to 2001, 42 patients with metastatic colorectal cancer after pre-treatment with a 5-FU bolus regimen were recruited in 5 centres to receive weekly 24-h infusions of 5-FU (2,600 mg/m 2 ) and S-FA (500 mg/m 2 ) dissolved in one pump for 6 weeks as second-line treatment. The treatment cycle was repeated after a 2-week rest period. Results: 106 6-week cycles (median 2, range 1-6 per patient) were administered during the study. The median follow-up was 22 months. Out of 42 patients, 1 (2%) achieved complete remission, 3 (7%) partial remission, and 31 (74%) no change. Median time to tumour progression was 5.7 months (95% Cl: 4.1-6.5). The median survival was reached at 14.7 months (95%CI: 11.0-22.0). Among major toxicities, NCI-CTC grade III/IV diarrhoea occurred in 8/42 (19%), grade III hand-foot-syndrome in 5/42 (12%) and grade III/IV stomatitis in 3/42 (7%) patients. Conclusion: Similar to conventional 24-h 5-FU + CA-FA treatment, the combination with S-FA in second-line therapy induced 9% objective responses and stopped tumour progression in 74%. The simultaneous administration of both, S-FA and 5-FU over 24 h dissolved in one pump is convenient, safe and effective as second-line treatment for patients with colorectal cancer.
