In the past five years, 5 out of 999 cases of uterine cervical cancer (0.5%) were found to be associated with eosinophilia in the peripheral blood, the tumor itself and the regional lymph nodes irrespective of whether they were metastatic or non-metastatic. In all five cases peripheral eosinophilia coincided with tumor eosinophilia. In four cases, no metastases were observed and eosinophilia came down to the normal range after operation. The patients are still living and well. In one case in which extensive node metastases and parametrial invasion were confirmed, eosinophilia remained abnormally high after the operation and the patient died in 2 years. Unlike the findings in the literature, our small series did not confirm a close link between peripheral eosinophilia and dissemination of malignancy but rather between both eosinophilia's. Our limited experience with this small series suggests that peripheral blood eosinophilia and tumor eosinophilia are not significant indicators for prognostication of malignancies as reports in the literature emphasize, but they can be used as a good tumor marker monitoring the progress or regress of malignancies when other causative factors for eosinophilia can be definitely excluded.Key words: Uterine cervical cancer associated with eosinophilia. eosinophilia and malignancy, eosinophllia as tumor maker, eosinophilia and prognosis, uterine cervical cancer, eosinophllia, tumor eosinophilia, peripheral blood eosinophilia, metastases of cancer
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
