Alpha1-AT phenotypes for 83 Jordanian cancer patients distributed as follows, 25 lung cancer, 25 prostate cancer and 33 with breast cancer, were tested using isoelectric focusing gel electrophoresis and immunofixation techniques.RESULTS: Isoelectric focusing results demonstrated that 96% of lung cancer patients were of PiMM phenotype and 4% of PiFM phenotype. All prostate cancer patients (100%) were found to be of PiMM phenotype. Phenotypes of breast cancer patients were 94% PiMM, 3% PiFM and 3% PiMS.CONCLUSION: These findings demonstrated that there were no significant differences in the distribution of alpha1-AT phenotypes among Jordanian patients with lung, prostate and breast cancer and they matched those reported for healthy individuals. Thus, we cannot recommend a given alpha1-AT phenotype for early diagnosis of the above mentioned types of cancer.
