CDDP combined chemotherapy was performed in 55 cases out of 229 prostatic cancer patients who were treated in Nara Medical University and Nara Prefectural Nara Hospital between January 1979 and August 1989. The previously untreated 33 patients received chemotherapy with anti-androgen treatment as an initial treatment, as well as 7 cases of unresponsive to antiandrogen treatment, 14 relapsing cases and one case with recurrence after total prostatectomy. The major regimens of chemotherapy were cis-diammine dichloroplatinum (CDDP) alone in 16 cases, PVB regimen (bleomycin or peplomycin + vincristine + CDDP) in 19 cases, and CAP regimen (cyclophosphamide + adriamycin + CDDP) in 16 cases. Complete response was not achieved or partial response was observed in 20 cases (34%), no change was seen in 20 cases (34%), and progression was seen in 19 cases (32%). Among each evaluable lesion, effects (CR + PR) were observed in 40% in the prostate, in 18% in the bone lesions, in 44% in the soft tissue lesions, and in 42% in the prostatic tumor marker. The 7-year survival rate of the chemotherapy group (35.6%) was better than that of the antiandrogen treatment group (26.6%) in stage D patients, but was not significant statistically When evaluated by the regimen, a partial response was observed in 56% of CDDP alone, in 21% of PVB regimen, and in 38% of the CAP regimen. However, there was no significant difference in survival rate among the regimens. As an adverse effect, myelosuppression and renal toxicity seemed to be dose limiting factors of CDDP combined chemotherapy for advanced prostatic cancer patients.

Due to the favourable results previously obtained with cisplatin in breast cancer (54% response rate), we studied a second-generation platinum analogue, carboplatin, in patients with previously untreated breast cancer. A total of 20 patients were entered in the study and all were evaluable. The median age was 57 years and all patients were in menopause. Karnofsky scores of 80-100 and 40-70 were registered in 14 and 6 cases, respectively. The predominant metastatic site was soft tissue in 12 subjects, visceral organs in 5 and bone in 3; 14 patients had greater than 2 metastatic sites. Carboplatin was given i.v. at a dose of 400 mg/m2 on day 1, with a 3-week rest period. In 13 patients who did not respond or whose disease recurred after carboplatin treatment, the CMFVP, CAP or FAC regimen was given as second line treatment. Carboplatin activity was observed in 4 patients [2 complete remissions (CRs) and 2 partial responses (PRs)], for a response rate of 20% (4/20); the 2 PRs were observed in soft tissue and bone and the 2 CRs, in lung, liver and bone. Remission lasted 2-10 months (mean, 4 months). CMFVP given as second-line chemotherapy to 13 patients produced 7 PRs (7/13, 54%). Toxicity was moderate, producing no drug-related deaths. Anemia (grade I-II) was recorded in seven patients; grade I-II leukopenia, in six; and grade III-IV leukopenia in two (median leukocyte nadir, 1,600/mm3). Thrombocytopenia was observed in three cases (grades I, II and III; median platelet nadir, 47,800/mm3). Unpleasant nausea/vomiting was pronounced (12 cases of grade III-IV) in 19 subjects. There were no cases of neuro- or nephrotoxicity. Due to permanent myelosuppression, no more than five cycles could be given. Our study showed that, unlike cisplatin, carboplatin given at a dose of 400 mg/m2 has low antitumorigenic activity in breast cancer patients and produces pronounced myelotoxicity. Additional first-line chemotherapy studies using carboplatin are needed to define the antitumorigenic activity of this platinum analogue.

The concept of using either alternating or sequential combination chemotherapy with non-cross-resistant combinations was tested in a randomized trial including 301 previously untreated patients with advanced epithelial ovarian carcinoma. The sequential schedule consisted of CAF (cyclophosphamide, doxorubicin, 5-fluorouracil) followed by PH (cisplatin, hexamethylmelamine) in nonresponders, CAF- greater than PH (n = 157), and the alternating regimen consisted of CAF/PH (n = 144). With a median observation time of 54 months, no statistically significant differences were found between the pathologically complete response (PCR) rates of 17% and 16%, respectively, nor were there any statistical differences in median disease-free survival for PCR patients (CAF- greater than PH 34+ months and CAF/PH 26+ months), in overall survival (28 and 24 months, respectively), or in time to treatment failure (10 and 11 months). The overall estimated cure rate was 13%. An equal degree of myelosuppression was seen with the two regimens, whereas neuro- and nephrotoxicity were more pronounced when PH was given sequentially to CAF than with the alternating schedule. We conclude that the sequential and the alternated use of doxorubicin- and platinum-based regimens yield equivalent results and that other approaches should be investigated to improve treatment effects.

Exposure to multiple non-cross-resistant drugs should increase cell kill and the chance of achieving more complete and partial responses. Our earlier study in breast cancer showed that second-line CAP (cyclophosphamide, adriamycin, cis-platinum) treatment was not cross-resistant to the CMFVP (cyclophosphamide, methotrexate, 5-fluorouracil, vincristine, prednisolone) regimen and produced a 51% response rate. These facts initiated a phase II study which used an alternating CMFVP/CAP regimen. Altogether, 49 patients entered the study and 45 were evaluated (greater than 2 cycles). The CMFVP regimen consisted of cyclophosphamide (200 mg/m2 on days 1, 2, 3, 4 and 5), methotrexate (30 mg/m2 on days 2 and 4), 5-fluorouracil (500 mg/m2 on days 1, 3 and 5), vincristine (1.4 mg/m2 on days 1 and 5), and prednisolone (40 mg p.o. on days 1-5), and was alternated with the CAP schedule (300 mg/m2 cyclophosphamide on days 1, 3 and 5, 50 mg/m2 adriamycin on day 1, and 30 mg/m2 cis-platinum on days 1, 3 and 5). Overall response was high, and 37 patients out of 45 responded (82%), with a 28% CR rate (13/45). A particularly high response rate was observed in soft tissues (86%, 18/21) and visceral organs (84%, 16/19). Only 1 patient progressed (3%). The duration of remission was 4-21+ months (median, 12 months). Six of 13 CR patients were still disease free 15 months after the treatment was stopped. The duration of survival was 5-25+ months (median, 15+ months). Toxicity was moderate (myelosuppression in 53% of patients, mainly grade I-II; stomatitis in 11%, except for 100% alopecia and 90% nausea and vomiting). One drug-related death (bone marrow aplasia) was recorded. The high antitumorigenic activity of the alternating regimen used is encouraging and may call for a randomized study for the ultimate evaluation of this treatment approach.

Based on the cell types in bronchogenic carcinoma, we treated 123 patients with different regimens of combination chemotherapy. The chemotherapy regimens consisted of CAP (cyclophosphamide + adriamycin + platinum) for 60 patients with adenocarcinoma and large cell carcinoma, PP (peplomycin + platinum) for 29 patients with squamous cell carcinoma and CAV (cyclophosphamide + adriamycin + vincristine) for 35 patients with small cell carcinoma. These regimens were repeated every 4 weeks for at least 2 cycles. The response rates for CAP, PP and CAV were 18.3% (11 PR), 20.7% (6 PR) and 60% (10 CR + 11 PR), respectively. Median survival time (MST) was 12.5 months for CAP, 8.5 months for PP and 9.5 months for CAV. Responders had a significantly (P less than 0.002) improved survival (MST, 15.5 months) compared to non-responders (MST, 7.5 months) in small cell carcinoma. However, there was no significant difference between responders and non-responders in CAP and PP. Survival of patients with PS 0-1 was significantly better than that with PS 2-3 in all treated patients. Nausea and vomiting were severe in patients treated with platinum-based polychemotherapy. There was no renal failure although a transient increase of serum creatinine was noted in CAP and PP. Myelosuppression was mild to moderate in all patients treated with CAP, PP and CAV.

Between April 1982 and March 1988, 28 patients with advanced urothelial cancer were treated with combination chemotherapy incorporating cisplatin at our hospital and the response was evaluated. Fourteen of them were managed by the CAP chemotherapy (cyclophosphamide 300-500 mg/m2 day 1, doxorubicin 30-50 mg/m2 day 1, cisplatin 40-90 mg/m2 day 2), 7 by the FAP chemotherapy (fluorouracil 300 mg/m2 day 1-5, doxorubicin 30 mg/m2 day 1, cisplatin 15 mg/m2 day 1-5) and 7 by the MEP chemotherapy (etoposide 100 mg/m2 day 1-3, cisplatin 20 mg/m2 day 1-5, methotrexate 300 mg/body day 6). Four patients (28.6%) responded to the CAP regimen; a complete response was gained in one patient who had pulmonary metastasis of excised ureteral cancer and a partial response in 3 patients with intravesical and nodal (N3, N4) cancer. A partial response was noted in 3 patients (42.9%) in the FAP group. They had intravesical lesions and two of them had regional node metastasis (N3). A higher response rate (85.7%) was obtained by the MEP regimen; a complete response in 2, who had intravesical and nodal (N2, N4) cancer, and a partial response in 4 patients, 1 had intravesical cancer, 1 had nodal (N2) and intravesical cancer and 2 had nodal or lung metastasis of excised renal pelvic cancer. Toxicity included mild to severe vomiting, alopecia, myelosuppression and mild renal or liver dysfunction. High dose metoclopramide provided a high degree of protection against cisplatin induced emesis. The results with the MEP regimen are promising for the advanced, metastatic urothelial cancer.

Thirty patients with metastatic carcinoma of the breast were treated with a combination of cyclophosphamide, Adriamycin (doxorubicin), and peptichemio (CAP) as an induction regimen, and maintenance regimen consisting of thiotepa, methotrexate, and 5-fluorouracil (TMF). Twenty-four patients were evaluable. Thirteen patients achieved an objective response for a response rate of 54.0% (complete remission plus partial remission). Median duration of response was 9.5 months (0-32+). The CAP regimen had severe myelotoxicity that led to dose reductions in 67% of patients. Furthermore, 50% of the patients required delay (greater than 28-day interval) in chemotherapy courses because of myelosuppression, and peptichemio had to be discontinued in seven patients. The CAP chemotherapy as an induction regimen for metastatic breast carcinoma resulted in underutilization of Adriamycin, and proved to be inferior to other Adriamycin-containing regimens. Although peptichemio used as a single agent had significant activity against breast cancer, it was not suitable for prolonged use in conjunction with other myelosuppressive agents. However, it may have a role in second-line therapy of metastatic breast cancer in conjunction with nonmyelosuppressive agents. The authors were unable to test the efficacy of non-cross-resistant maintenance therapy with TMF in this trial.

In an attempt to improve upon the 43%-48% regression rates noted for various CAP regimens consisting of cyclophosphamide, doxorubicin (Adriamycin), and cis-diamminedichloroplatinum(II) in various doses and schedules, triazinate was added to that three-drug combination, and the new combination (T-CAP) was evaluated in patients with advanced adenocarcinoma of the lung. T-CAP produced a regression rate of 57% with a 7-week increase in overall median time to progression and a 4-week increase in overall median survival compared to the best of the CAP schedules. More stomatitis and dermatitis were noted with the new combination, but myelosuppression was similar to that of the CAP regimens. These data suggest that further studies with triazinate should be conducted in patients with adenocarcinoma of the lung.

Twenty-seven patients with measurable or evaluable, regionally advanced or metastatic head and neck cancer were given a combination of cyclophosphamide (C), Adriamycin (A), and cis-diamminedichloroplatinum (II) (P). Most patients had received extensive prior surgery and/or radiation therapy. Among 25 evaluable patients, the overall response rate was 64% (16/25) with 3/25 complete responders and 13/25 partial responders. The median survival for the entire group of 25 patients and the median response duration for the subset of 16 patients experiencing tumor regression were 8.1 and 7.0 months, respectively. Responders lived significantly longer than nonresponders (11 months vs. six months, P less than 0.01). According to covariate analysis, the difference seems to reflect the influence of response to treatment and not other confounding variables. Almost all patients experienced anorexia, nausea, vomiting, and a pervasive feeling of ill-health. In fact, six patients declined further treatment and five of these had objective tumor regressions. Recurrent disease was detected three months following discontinuation of chemotherapy in four of these five patients and seven months later in the fifth. Myelosuppression was clinically acceptable and there was in this dosage and schedule no evidence of hepatic or renal impairment. Although the CAP regimen has substantial antitumor activity, the program is clinically rigorous and should remain an investigational treatment modality at the present time.
