Change in Homocystein Concentration From Screening

Blood samples for folate biomarker (homocystein) analysis were collected at Screening, Day 2 and Day 5 (End of study visit). Changes from screening to later visits were counted. The criteria for assessment categories normal, low and high were based on the reference ranges for plasma-Homocystein as follows: low \<4,7 mcmol/L; normal =\> 4,7 and \<=16 mcmol/L; high \>16 mcmol/L. Values were applicable for both male and female adults.

Time frame: Samples taken at Screening visit, Day 2 and End of Study (Day 5)

Population: The Per Protocol analysis set contained 29 of the 32 enrolled patients. One patient was withdrawn prior to study drug administration and two patients were excluded due to major protocol deviations.

Gene Expression Ratios (Mucosa:Tumor)

Concentration of different genes involved in folate transport and metabolism were analysed in both tumor and adjacent mucosa. The concentration in mucosa was divided by the concentration in tumor. A value above 1 indicate that the gene expression was higher in mucosa than in tumor and a value below 1 that the gene expression was higher in tumor than in mucosa.

Time frame: Sample taken Day 1 (Day of Surgery)

Population: The Per Protocol analysis set contained 29 of the 32 enrolled patients. One patient was withdrawn prior to study drug administration and two patients were excluded due to major protocol deviations.
