Abstract/Text
OBJECTIVE: Taste disturbance is known to occur as one of the adverse events associated with chemotherapy for gynecological cancer, but few studies have attempted to assess it in practical terms. Therefore, a range of taste tests was performed in gynecological cancer patients.
METHODS: The patients were 23 women with gynecological cancer being treated with anticancer agents. Subjective symptoms of altered taste were classified, and objective findings were obtained with the following four gustatory tests: serum trace element (zinc, copper, iron) levels, tongue cultures, electrogustometry, and the filter paper disc tests.
RESULTS: Of the 23 subjects, 11 perceived taste disturbances. The serum zinc level was consistently below the lower limit of normal. On tongue cultures, indigenous bacteria were seen in all patients during the entire treatment period. Electrogustometry revealed a tendency for the development of hypogeusia in the chorda tympani nerve field. Conversely, hypergeusia tended to develop gradually in the greater petrosal nerve field. The filter paper disc test revealed a tendency for the development of hypergeusia for sweetness, saltiness, and sourness in the chorda tympani nerve field. Hypogeusia for bitterness tended to develop with increasing number of chemotherapy cycles. The glossopharyngeal nerve field exhibited the same tendencies as observed in the chorda tympani nerve field. In the greater petrosal nerve field, there was a tendency for the development of hypergeusia for sweetness, sourness, and bitterness.
CONCLUSIONS: Abnormal test results were seen in half of patients after cancer chemotherapy.
