[Successful treatment of pleuritis carcinomatosa using combination therapy of 5'-DFUR, MPA and CPA as maintenance therapy].

A 44-year-old female patient with inoperable, local advanced left breast cancer was treated with 3 cycles of high dose CAF therapy followed by combination therapy of 5'-DFUR, MPA and CPA. The patient was discharged after receiving 3 cycles of high-dose CAF therapy and continued to receive daily oral doses of 5'-DFUR (800 mg), MPA (800 mg), and CPA (100 mg) for 15 months. After 3 cycles of high-dose CAF therapy, tumor marker (CEA, CA 15-3) levels were reduced. Six months later, after 3 cycles of high-dose CAF therapy, the tumor marker levels were within the normal range. No serious side effects were observed during chemotherapy. The patient enjoyed a good quality of life. We thus confirmed that this combination regimen was effective as a maintenance therapy for local advanced breast cancer.
