Seventeen patients, 14 after radiation therapy relapse, with measurable nasopharyngeal carcinoma were treated with chemotherapy. Remissions were observed in 9 of 17 (53%) with 3 complete (CR) and 6 partial responses (PR). Five (2 CR + 3 PR) of seven patients with lymphoepithelioma achieved remission, 4 (1 CR + 3 PR) of 8 with keratinizing squamous cell carcinoma, and 2 progressions with transitional cell carcinoma. Complete remissions were only achieved with CDDP‐based combinations, with 2 of the 3 CR rendered histologically free of disease at the time of repeat biopsy of the tumor bed. Nasopharyngeal carcinoma is responsive to chemotherapy, even after radiation therapy relapse. The most effective chemotherapy combinations contain CDDP. Histologic differentiation did not appear to influence the frequency of remissions.
9109 Background: The effect of using IV iron sucrose in managing cancer chemotherapy-related anemia has not been previously reported. To investigate this issue, we conducted a randomized study of IV iron sucrose in patients (pts) with cancer chemotherapy-related anemia who completed 8 prior wks of ESA therapy. Methods: This prospective, multicenter, randomized, open label, Phase III clinical trial enrolled 375 pts with chemotherapy induced anemia (Hgb levels = 10.0 g/dL) and was conducted in 2 stages. During Stage I (8-wk duration), pts received treatment with fixed ESA doses (100-mcg of darbepoetin or 40,000 units epoetin wkly or 200 mcg of darbepoetin every other wk). Pts were classified as either ESA responders (= 1 g/dL increase in Hgb) or ESA non-responders with each group randomized (Stage 2) separately to receive either 12 wks of fixed doses of ESA plus up to 1,500 mg of iron sucrose (given in 3 divided doses of up to 500mg) or 12 wks of fixed doses of ESA alone. Laboratories (including iron indices and acute phase reactants), quality of life and adverse events were assessed at baseline and throughout. Results: Iron sucrose plus ESA compared to ESA alone resulted in greater mean maximum Hgb levels and greater number of pts who achieved Hgb increases = 2.0 and ≥ 3.0 g/dl in both prior ESA responders and non-responders. There was also a statistically significant improvement in fatigue and iron stores in the iron sucrose treated pts. Baseline iron status did not predict responsiveness to iron sucrose therapy. Three serious but non-life threatening iron sucrose related adverse events were observed including one case of significant, transient hypotension in a female weighing 50 kg. Conclusions: IV iron sucrose increased Hgb levels and iron stores significantly and is well tolerated in doses up to 500 mg increments in ESA treated patients with cancer chemotherapy- related anemia. IV iron sucrose should be considered in combination with erythropoietic therapy in anemic cancer patients receiving chemotherapy. [Table: see text]
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.
