pirarubicin and doxifluridine

Twenty-four eligible patients (23 of whom were evaluated) with advanced and metastatic breast cancer were treated at the Saitama Cancer Center every 4 weeks with pirarubicin (30 mg/m2 i.v., day 1 and 8), cyclophosphamide (200 mg/m2 div, day 1 and 8) and doxifluridine (800 mg/day po, day 1-14). The 23 evaluable patients had a median age of 49.7 years (range 35.3-72.1) and underwent a median number of 3 cycles (range 2-5). Grade 4 leukopenia (10/24 patients) was the dose-limiting factor and led to infection in one patient. Four complete responses and 7 partial responses with a median duration of 12.1 months (range 2.6-61.0) were achieved, resulting in an overall response rate of 47.8%. The 50% survival duration was 22.9 months.

We conducted a randomized controlled study to evaluate the clinical usefulness of (2"R) -4'-O-Tetrahydropyranyladriamycin (THP)-based combination therapy subsequent to induction therapy which was consisted with THP, 5'-DFUR, and CPA in the treatment of advanced or recurrent breast cancer. In maintenance therapy, Arm C received CPA and TAM, and Arm T received these two drugs plus THP. Survival time of 50% for all cases in which maintenance therapy was conducted was 26.9 months in Arm T and 20.9 months in Arm C, showing no significant difference by the log-rank test (p = 0.64). Survival time in all cases in which therapy had been completed was 54.6 months in Arm T and 28.1 months in Arm C, showing a significant difference by the log-rank test (p = 0.03) although the number of cases was few. A few cases showed a decrease in total leukocyte count to below 2,000/mm3 at the time of induction therapy, but this was transient in all cases. No significant difference in count was noted between two arms at the time of maintenance therapy. However, many cases in Arm T showed decreased total leukocyte count and hemoglobin content, and thrombocytopenia. These results suggest that combination therapy including THP conducted as maintenance therapy after induction is useful in the prolongation of survival time in patients with advanced or recurrent breast cancer.

We herein report the case of a bladder tumor in an 85-year-old man who had been engaged in phenacetin abuse. He had been taking phenacetin owing to migraine headaches since he was 45 year of age. His total intake of phenacetin was approximately 7.3 to 11.5 kg over a period of years. He visited the Department of Urology in our hospital due to gross hematuria and pain on urination. IVP and a pelvic CT scan revealed a tumor mass on the right lateral wall of the urinary bladder. TUR-BT was performed. A histopathological examination of the resected specimen was diagnosed as urotherial carcinoma, grade 2∼3, pT2N0M0. To our acknowledge, only 24 cases of urotherial tumors owing to phenacetin abuse have been previously reported in the Japanese literature, making this the 25 th such case to be reported in Japan.

What should be the standard treatment for taxane-refractory metastatic breast cancer remains controversial. In this paper, a case in which the 5'-DFUR + CPA + THP therapy was effective for paclitaxel-refractory metastatic breast cancer is reported. A 41-year-old female received pectoral muscle preserved mastectomy under diagnosis of the left breast cancer in May 1996. In June, 1999, a coin lesion of 2.2 cm diameter was found in the left middle lung field with chest X-ray. Paclitaxel 210 mg/m2 (once for three weeks, 8 cycles in total) resulted in marked improvement. The regimen of paclitaxel 70 mg/m2 (medication consecutive once-weekly for three weeks, and withdrawal for next week; 1 cycle) was carried out continuously with the patient ambulatory. Because resistance to the treatment appeared at the time the total dose reached 2,700 mg, 5'-DFUR + CPA + THP therapy (THP 30 mg/m2 (i.v.) x day 1, CPA 77 mg/m2 (p.o.) x 14 days, 5'-DFUR 460 mg/m2 (p.o.) x 14 days; 3 weeks with 1 cycle) was carried out, and definite improvement in the lung findings were observed. 5'-DFUR + CPA + THP therapy may be of use as a second-line therapy in paclitaxel-refractory recurrent breast cancer.

The case of a 49-year-old woman with axillary lymph nodes, multiple bone and multiple lung metastases from advanced breast cancer is reported. The patient responded remarkably to combination chemo- and endocrine-therapy. This patient was discharged after receiving 2 cycles of cyclophosphamide, pirarubicin and 5'-DFUR, while continuing to receive daily oral doses of 5'-DFUR and MPA. The patient experienced few adverse effects during chemotherapy. The patient enjoys an improved quality of life. This combined regimen has been confirmed to be an effective treatment for patients in advanced stages of breast cancer.

A 75-year-old male was admitted one year after surgery for advanced gastric cancer. He was diagnosed as having multiple liver metastases with elevated serum CEA level. Combination chemotherapy consisting of THP-ADM, MMC and 5'-DFUR was done in the outpatient clinic. As a result, both multiple metastatic liver tumors and serum CEA level showed a remarkable response.

In the preclinical study of a new combination therapy for gastric cancer, dFTP, consisting of doxifluridine (5'-DFUR), pirarubicin (THP) and cisplatin (DDP) as a modification of conventional FAP regimen (5-fluorouracil+Adriamycin+DDP), we compared antitumor and toxic effects of two sequential treatment schedules, single injection of DDP before or after 4 daily administrations of 5'-DFUR, on 5 strains of human gastric cancer bearing nude mice. Results indicated that both schedules of the dFTP regimen had potent antitumor effects. There was no significant difference between them. On the other hand, in terms of the host toxicity as observed by body weight loss, the post-DDP schedule was significantly less toxic than pre-DDP. These results suggest that dFTP regimen (post-DDP schedule) may be useful for clinical treatment of gastric cancers.

We reported a patient with advanced gastric cancer and a liver metastasis, who responded remarkably to combination chemotherapy using THP, 5'-DFUR and CDDP. The patient was administered four courses of THP (15 mg/m2/day, on day 1, iv), 5'-DFUR (1400 mg/m2/day, on days 1-4 and 15-18, orally), and CDDP (80 mg/m2/day, on day 5, iv) every 4 weeks. As a result, both the primary and metastatic tumors decreased remarkably in size at more than 19 weeks (PR) and we performed curative total resection of the stomach and partial resection of the liver. Histologically, the effects of chemotherapy on gastric focus were evaluated as grade 1a and the liver metastasis completely disappeared. This combination therapy proved useful to treat advanced gastric cancer in this patient.

In vivo antitumor activity of pirarubicin (THP) and epirubucin (EPI) in combination with doxifluridine (5'-DFUR) and cisplatin (CDDP) were examined using mouse P388 leukemia. THP (1.25-7.5 mg/kg) or EPI (1.25-15 mg/kg) was given intravenously on day 1, and then 5'-DFUR (125 or 250 mg/kg/day) and CDDP (4 mg/kg) were given orally on days 1-4 and intravenously on day 5 after tumor inoculation, respectively. Both THP and EPI enhanced the antitumor of a combination of 5'-DFUR and CDDP. The enhancement by THP was additive or synergistic, while that by EPI was additive. Cured animals were observed in the combination of THP with the two drugs, but not in that of EPI. Thus, in combination with 5'-DFUR and CDDP, THP was more effective against P388 leukemia than was EPI. The combination therapy using THP, 5'-DFUR and CDDP may be a novel chemotherapeutic approach to a variable type of tumors in clinical trials.
