M-->F and CMF are effective for node-negative patients with ER-negative tumors. The incidence of local-regional or distant metastases and IBTR decreased after either therapy. The benefit from either therapy was evident in all patients, but the CMF advantage was greater in those F may be used in patients with medical problems that would preclude CMF administration.

We evaluated the postoperative use of sequential methotrexate and fluorouracil followed by leucovorin in 679 patients with primary breast cancer, histologically negative axillary nodes, and estrogen-receptor-negative (less than 10 fmol) tumors. No survival advantage was observed with this therapy as compared with no postoperative therapy during four years of follow-up (87 percent vs. 86 percent; P = 0.8). However, there was a significant prolongation of disease-free survival among women who received this therapy as compared with those who did not (80 percent vs. 71 percent; P = 0.003). An advantage was observed in both the patients less than or equal to 49 years old and those greater than or equal to 50. At four years, treatment failure was reduced by 24 percent in the younger group and by 50 percent in the older group. The rates of both local and regional and distant metastases were decreased. These benefits, achieved without the use of an alkylating agent, were associated with tolerable side effects. Multivariate analysis testing for potential interactions failed to identify subgroups of patients who did not benefit from the therapy. These results, although promising, do not obviate the need for additional trials to evaluate potentially better regimens of therapy, but they do suggest that sequential methotrexate-fluorouracil should be used in the control arm in such studies. Their use is also justified for the treatment of patients who refuse to participate in clinical trials, provided the patients meet the eligibility criteria of the present study. Since women with tumors too small for conventional analysis of estrogen-receptor and progesterone-receptor concentrations were not included in this study, we do not recommend systemic treatment for them outside of a clinical trial.

ObjectiveThe authors present their 35-year experience with intra-arterial chemotherapeutic regionai perfusion of 1 139 patients with melanomas, using an extracorporeal oxygenated circuft and heart-lung apparatus. Summary Background DataIntra-arterial chemotherapy produces improved responses in many tumors. By isolating and sustaining the area with extracorporeal oxygenated circulation, high doses can be delivered to the tumor area, limited only by local toxicity. Drug levels up to 10 times those achieved by systemic administration are obtained. MethodsTechniques for hyperthermic perfusion were developed for limbs, pelvis, head, neck, and skin of the breast. Melphalan (Burroughs Wellcome, Research Triangle Park, NC) was used in 753 patients. Combinations with melphalan or other drugs were used in remaining cases at temperature of 38 to 40 C for 30 to 60 minutes. ResultsChemotherapy perfusion followed by tumor excision or node dissection, was performed where indicated. The cumulative 1 0-year survival for patients with localized melanomas was 70%. For patients with local recurrences or satellites within 3 cm, survival was 61 %. For those with regionally confined intransit tumors, survival was 30%; for those with regional node involvement, 38%; for those with intransit and nodal metastases, 16%; for those with distant metastases and perfusion-mainly to save functional limbs-survival was 7%. Multiple perfusions were performed in 158 patients with recurrent disease on 366 occasions. Patients with indolent regionally confined melanomas were benefited by prolongation of useful life. ConclusionsSafe perfusion techniques are available for most anatomic regions. Increased chemotherapeutic doses are delivered to isolated areas limited only by local toxicity. Adjunct perfusion in poor prognosis stage cases is useful in reducing local recurrence, and intransit or lymph node metastases. Regional perfusion reduces the need for major amputation. Multiple perfusion can be useful in treating recurrent chronic melanoma. 520
