Stewart-Treves syndrome is a rare cutaneous angiosarcoma with a poor prognosis. Physicians must be aware of this lethal syndrome, especially in patients who have been treated for breast cancer with radiation and lymph-node dissection (such as the case reported here). Patients who develop unexplained enlarging plaques of coalescing purple papules should have immediate biopsy for early diagnosis of Stewart-Treves syndrome. MRI, along with PET/CT, can help evaluate the extent of disease and help with treatment strategies.
Treatment for extensive indolent lymphoma should combine optimization of efficacy without excessive toxicity. Rituxan may be an ideal agent for combinations with chemotherapy because of its non-cross-resistant toxicity profile and the potential for synergism. We present the results of 32 patients with indolent B-cell NHL who received a novel three-drug combination designed with the intent of preservation of both efficacy and quality of life. Patient characteristics were as follows, median age, 58 years (36-75 years); histology, follicular 16, SLL/CLL five, lymphoplasmacytic six, marginal cell five; relapsed or refractory, 10; untreated, 22. Patients first received cyclophosphamide 800 mg/m(2) and mitoxantrone 8 mg/m(2), iv on the same day, every 3 weeks for two cycles. Subsequently, patients received rituximab followed by mitoxantrone 8 mg/m(2) every 2 weeks for four cycles. The regimen, and particularly rituximab, was extremely well tolerated. Grade I/II, infusion-related toxicity was noted in 10%. Six patients achieved a PR and 23 a CR for an overall response of 90% (95% CI: 79-100%). The actuarial median TTP for all patients was 30 months. Molecular remissions were noted in 8/14 patients tested in CR. We conclude that the cyclophosphamide-mitoxantrone-rituxan (CyMiR) regimen is effective and extremely well tolerated. Furthermore, rituximab infusion-related morbidity is nearly completely eliminated.
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.
