Safety and efficacy of isolated perfusion of extremities for recurrent tumor in elderly patients

Background. The treatment of bulky recurrent melanotic lesions of extremities with isolated limb perfusion with high dose chemotherapy offers palliation in a number of patients. However, the question is raised whether these major surgical procedures are too risky to warrant performing them in elderly patients. Methods. Sixty-seven limbs were perfused in 60 patients with various drugs from 1976 through 1996 (35, imidazole carboxamide; 7, cisplatin; 20, carboplatin; 5, thiotepa). Among the 67 perfusions, 20 were in patients aged 70 years and older Perfusion was performed for 16 upper extremities and 51 lower extremities by using the pump oxygenator for 1 hour. Results. A total of 19 complications were noted after a total of 14 of the 67 perfusions (21 %) (postoperative edema, 5; seroma, 4; wound separation or infection, 9; nonfatal pulmonary embolus, 1). The complications in 4 of 20 perfusions in the older patients (20 %) were less than in IS of 47 perfusions in the younger patients (32 %). Among the 17 patients older than 70 years of age who were treated with perfusions for recurrent disease, four patients (24 %) are alive with no evidence of disease (NED) for a median of 29 months (range, 16 to 80 months); one patient is now more than 6 years with NED after her third perfusion for repeated in-transit disease. Another 2 of 17 patients (12 %) are alive with disease for a median of 89 months (range 54 to 123 mos). The remaining 21 patients (64 %) are dead of their disease. These data are comparable to the control rates in the group of younger patients in the study Overall, half of all the patients (14 of 28) who died of their disease in bath groups had maintained local control of their involved extremities. Conclusions. Aggressive treatment in selected patients with regional isolated perfusion of limbs for melanoma can lead to significant palliation of symptoms and salvage of limbs with adequate disease-free control and occasional survival benefit. This series of patients was associated with meaningful disease control and with few serious complications. Perfusions are tolerated well by patients in their 70s and 80s; therefore advanced age is not a contraindication to this procedure in carefully selected patients.
