title: Selection of quantitative criteria for evaluating metastases of a highly metastatic salivary adenoid cystic carcinoma cell line to the lungs of nude mice.
abstract: OBJECTIVE
  To select reliable quantitative criteria for evaluating metastases of a highly metastatic salivary adenoid cystic carcinoma cell line (ACC-M) cell to the lungs of nude mice.
  
  
  METHODS
  The within-group coefficients of correlation of 5 parameters were measured from lung slides using a video image digital analysis system (VIDAS), and the intergroup coefficients of correlation of 6 sets of parameters from all the lungs, which were taken from ACC-M lung metastases models, were calculated and statistically analyzed.
  
  
  RESULTS
  The within-group coefficients of correlation of 5 parameters are as follows: ratio of area of metastases, t = 0.9 (P < 0.001); area of metastases, t = 0.7 (P < 0.05), size of lung section, numbers of metastases, and size of the largest metastatic focus all t < 0.4 (P > 0.05). The intergroup coefficients of correlation of the parameters are as follows: ratio of area of metastases was assigned 1, weight of the lung was 0.9755, and area of metastases was 0.8628.
  
  
  CONCLUSIONS
  For evaluating lung metastases of ACC-M, the ratio of area of metastases and weight of the lung are precise; the area of metastases is also significant within the 6 quantitative parameters.
