1/3. Panmucositis and chemosensitisation associated with betel quid chewing during dose-dense adjuvant breast cancer chemotherapy.PURPOSE: The severity of chemotherapy-induced oral mucositis has previously been reported to be greater in patients who chew betel quid (areca), an addictive habit shared by hundreds of millions of individuals worldwide. Here, we report a case of fulminant panmucositis complicating dose-dense adjuvant breast cancer treatment in a betel-chewing patient without evidence of other risk factors. methods: Grade IV mucositis was triggered by the initial use of standard-dose anthracycline chemotherapy, and involved not only the mouth but also the genital and anal mucosa, as well as other severe non-mucosal toxicities. RESULTS: Despite subsequent treatment with dose-reduced CMF and docetaxel regimens-which are seldom associated with mucosal toxicity at these dose intensities in the absence of neutropenia-high-grade oral mucositis continued to complicate the therapeutic course. CONCLUSION: These observations suggest that the potentiation of chemotherapy-induced mucositis by quid chewing may not be mediated solely by local effects on the oral epithelium, but also involves the systemic absorption of toxic chemosensitising molecules.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
2/3. epidemiology of treatment-associated mucosal injury after treatment with newer regimens for lymphoma, breast, lung, or colorectal cancer.goals of work: Oral and gastrointestinal (GI) mucositis are frequent complications of chemotherapy and radiotherapy for cancer, contributing to not only the morbidity of treatment but its cost as well. The risk associated with specific chemotherapeutic agents, alone and in combination, has been characterized previously. In the current study, we sought to estimate the risk associated with newer regimens for the treatment of non-Hodgkin's lymphoma (NHL) and common solid tumors. methods: We reviewed published studies reporting phase II and III clinical trials of dose-dense regimens for breast cancer and NHL, TAC (docetaxel, adriamycin, cyclophosphamide) chemotherapy for breast cancer, and infusional 5-fluorouracil-based regimens for colorectal cancer. platinum-, gemcitabine-, and taxane-based regimens for lung cancer, either alone or in combination with radiotherapy, were also considered. Using modified meta-analysis methods, we calculated quality-adjusted estimates of the risk for oral and GI mucositis by tumor type and regimen. case reports are used to emphasize the relevance of the findings for patient care. Main results: Our findings demonstrate that mucosal toxicity remains an important complication of cancer treatment. Moreover, innovations in drug combinations, scheduling, or mode of administration significantly modulate the risk for both oral and GI mucositis. Conclusions: Ongoing review of the clinical trial experience will remain important as newer, targeted agents enter standard clinical practice.- - - - - - - - - - ranking = 2keywords = cancer (Clic here for more details about this article) |
3/3. Alimentary mucositis: putting the guidelines into practice.BACKGROUND: The mucositis Study Group of the Multinational association of Supportive Care in Cancer and International Society of Oral Oncology completed an evidence-based review of the literature for the management of alimentary mucositis. DISCUSSION: The present manuscript puts these guidelines into clinical practice by presenting two cases of alimentary mucositis from cancer therapy. These cases illustrate the impact of oral and gastrointestinal mucositis on patient care.- - - - - - - - - - ranking = 0.2keywords = cancer (Clic here for more details about this article) |
