title: Analysis of in vitro and in vivo sensitivity of oral cancer cells to methotrexate.
abstract: OBJECTIVE
  The present study was directed on the assessment of the response of treatment-naive oral cancer cells to methotrexate (MTX) in vitro: and clinical response to MTX therapy.
  
  
  METHODS
  A pilot study of in vitro: evaluation of MTX response of oral cancer cells from 10 patients was conducted using a cell viability assay to determine the sensitivity/resistance to MTX. Quantitative in vitro: data were correlated to the clinical outcome to MTX therapy.
  
  
  RESULTS
  A positive correlation was observed between the effect of MTX on tumor cells in vitro: and clinical response for 7 out of 10 patients.
  
  
  CONCLUSIONS
  Observations from the proof-of-principle pilot study suggests that oral cancer cells have intrinsically variable response to MTX. Confirmation of these findings with a larger cohort of patients could aid in the development of individualized therapies for this class of malignancy.
