Quality of life after isolated limb infusion for in-transit melanoma of the extremity.
BACKGROUND: Isolated limb infusion (ILI) has been associated with persistent edema, numbness, pain, and functional impairment of the treated limb. However, health-related quality of life (HRQOL) has not yet been assessed using a validated questionnaire. METHODS: Functional Assessment of Cancer Therapy-Melanoma (FACT-M) questionnaires were collected from subjects enrolled a phase I ILI trial with temozolomide at baseline and 2, 6 weeks, and 3 months post-ILI. Of 28 enrolled patients, 19 patients received maximum tolerated dose of temozolomide and are included in the HRQOL analysis. Clinical and operative variables and treatment response data also were collected. RESULTS: HRQOL scores showed a trend of improvement from baseline through 3-months post-ILI as measured by FACT-M and the melanoma surgery scores. There were no differences in HRQOL when patients were stratified by disease burden, clinical toxicity level, and 3-month disease response. Additionally, fewer patients complained of pain, numbness, and swelling of the affected limb at 3 months post-ILI compared to baseline, and also these symptoms were improved at the immediate postoperative visit compared with baseline. CONCLUSIONS: Despite the known morbidity of ILI, we have demonstrated with a validated HRQOL questionnaire that HRQOL is not adversely impacted at therapeutic doses of temozolomide delivered intra-arterially from baseline through 3 months posttreatment. Patient centered-outcomes should be evaluated as a standard part of all future regional therapy trials using standardized melanoma-specific HRQOL questionnaires to more completely evaluate the utility of this type of treatment strategy.
