Table 3: Most of the patients had multiple pathologies and many had more than one potential explanation for the altered AST-ALT enzyme pattern. The likely dominant etiologic factor was determined from the laboratory data and clinical history. Further breakdown of the various malignancies is presented in table 4. The pathologies present in the ten cases in which the primary cause could not be ascertained with confidence are given in table 5
