RESUMEN
PURPOSE: Glucose-6 phosphate dehydrogenase (G6PD) deficiency has an estimated prevalence of 5 -7.5% of the global population. Administration of some drugs in G6PD deficient patients may result in clinical conditions of varying severity, including potentially fatal sequels. For these reasons, in case of G6PD deficiency, the use of high dose toxic chemotherapy regimens in potentially curable malignancies with associated risk of tumor lysis syndrome, such as in advanced germ cell tumors, raises both physicians' preoccupations and issues for safeguard patients' health. Nonetheless no systematic information is actually available for safety in premedication to be administered, chemotherapy regimens adopted, and supportive care drugs needed to be provided in some particular situations. METHODS: We present a case of a patient with metastatic testicular cancer and known g6pd deficiency, admitted in our department. We also performed a literature review in tree medical libraries searching for articles addressing the overmentioned security issues. RESULTS: Available literature is particularly scant. nonetheless, there is no evidence contradicting the administration of cytotoxic chemotherapy to G6PD deficient individuals. Our patient was able to complete the preplaned chemotherapy cycles, without any complications. CONCLUSION: Given the absence of data supporting the limitation of chemotherapy to G6PD deficient patients, the latter should not be deprived of the indicated antineoplastic treatment. However, certain premedication agents must be avoided. Continuous patient monitoring during treatment may alleviate physicians' and patients' anxiety and preoccupations.
