Patients were classified as having high hENT1 expression if the mean H score for their cores was above the overall median H score (48). High and low hENT1-expressing groups were compared using Kaplan-Meier curves, log-rank tests, and Cox proportional hazards models. All statistical tests were two-sided.Three hundred eighty patients (87.6%) and 1808 cores were suitable and included in the final analysis. Median overall survival for gemcitabine-treated patients (n = 176) was 23.4 (95% confidence interval [CI] = 18.3 to 26.0) months vs 23.5 (95% CI = 19.8 to 27.3) months for 176 patients treated with 5-fluorouracil/folinic acid (χ(2) 1=0.24; P = .62). Median survival for patients treated with gemcitabine was 17.1 (95% CI = 14.3 to 23.8) months for those with low hENT1 expression vs 26.2 (95% CI = 21.2 to 31.4) months for those with high hENT1 expression (χ(2)₁= 9.87; P = .002). For the 5-fluorouracil group, median survival was 25.6 (95% CI = 20.1 to 27.9) and 21.9 (95% CI = 16.0 to 28.3) months for those with low and high hENT1 expression, respectively (χ(2)₁ = 0.83; P = .36). hENT1 levels were not predictive of survival for the 28 patients of the observation group (χ(2)₁ = 0.37; P = .54). Multivariable analysis confirmed hENT1 expression as a predictive marker in gemcitabine-treated (Wald χ(2) = 9.16; P = .003) but not 5-fluorouracil-treated (Wald χ(2) = 1.22; P = .27) patients.Subject to prospective validation, gemcitabine should not be used for patients with low tumor hENT1 expression. | Gov't Doc #: | 24301456 | URI: | https://ahro.austin.org.au/austinjspui/handle/1/11976 | DOI: | 10.1093/jnci/djt347 | Journal: | Journal of the National Cancer Institute | URL: | https://pubmed.ncbi.nlm.nih.gov/24301456 | Type: | Journal Article | Subjects: | Adenocarcinoma.drug therapy.metabolism.mortality Adult Aged Antimetabolites, Antineoplastic.therapeutic use Antineoplastic Combined Chemotherapy Protocols.therapeutic use Deoxycytidine.analogs & derivatives.therapeutic use Disease-Free Survival Equilibrative Nucleoside Transporter 1.metabolism Europe.epidemiology Female Fluorouracil.administration & dosage Humans Kaplan-Meier Estimate Leucovorin.administration & dosage Male Middle Aged Pancreatic Neoplasms.drug therapy.metabolism.mortality Treatment Outcome Tumor Markers, Biological.metabolism |
