A comparison of intermittent vs. continuous and of adriamycin vs. methotrexate 5-drug chemotherapy for advanced breast cancer. A Cancer and Leukemia Group B study

The therapeutic effectiveness of intermittent vs. continuous combination chemotherapy and of the substitution of adriamycin for methotrexate in a 5-drug regimen was evaluated in women with metastatic breast carcinoma. Patients were randomly allocated to receive continuous therapy with cyclophosphamide, methotrexate, 5-fluorouracil, vincristine, prednisone ( CMFVP -C, 86 patients), intermittent CMFVP ( CMFVP -I, 109 patients), or intermittent CAFVP (107 patients). The CR + PR rate with CAFVP (71%) was superior to CMFVP -C (50%, p = 0.003) and to CMFVP -I (50%, p = 0.002). The remission duration with CAFVP (14 months, median) was superior to CMFVP -I (7 months) (p less than 0.01), and tended to be superior to CMFVP -C (9 months) (p = 0.07). There was a survival advantage of CAFVP (19 months, median) over CMFVP -I (13 months) (p = 0.01), but not over CMFVP -C (16 months) (p = 0.24). Among CR + PR patients, the survival with CAFVP (29 months, median) was superior (p = 0.02) to both CMFVP -I (18 months) and CMFVP -C (21 months). The CMFVP -C regimen was associated with the highest incidence of leukopenia and neurologic toxicity, but the lowest incidence of GI toxicity. The results indicate that the CAFVP regimen is well tolerated and is superior to the CMFVP regimens.     

Combined modality treatment of locally advanced breast cancer: Adjuvant combination chemotherapy with and without doxorubicin

Forty-one women with non-metastatic but locally advanced breast cancer were treated by modified radical or radical mastectomy, and were then randomized to receive one of two adjuvant chemotherapy regimens. Regimen A consisted of 6 months of cyclophosphamide, adriamycin, and fluorouracil (CAF) followed by 6 months of cyclophosphamide, methotrexate, fluorouracil, vincristine, and prednisone (CMFVP). Regimen B was 12 months of CMFVP. Patients were stratified for estrogen-receptor status, and all patients with a positive estrogen receptor value received tamoxifen 20 mg bid in addition to the chemotherapy. Eight of 21 patients randomized to Regimen A are alive and free of disease, whereas only 1 of 20 patients on Regimen B is well. A trend toward improved disease-free survival favoring Regimen A was observed (P = .05), although a significant difference in overall survival has not been demonstrated. Our findings support the continued study of adriamycin-containing regimens in the adjuvant setting and in combined modality therapy of locally advanced breast cancer.     

Dose-intense weekly cyclophosphamide, methotrexate, 5-fluorouracil, vincristine and prednisolone (CMFP) in advanced breast cancer

Weekly chemotherapy with cyclophosphamide 80 mg m-2 day-1 p.o. continuously, methotrexate 35 mg m-2 week-1 i.v., 5-fluorouracil 500 mg m-2 week-1 i.v., vincristine 1.4 mg m-2 i.v. every two weeks and prednisolone 20 mg m-2 day-1 p.o. continuously (CMFVP) was prospectively studied in 45 previously untreated outpatients with advanced breast cancer to determine the feasibility of delivering a dose-intense regimen. Of 40 evaluable patients, complete response (CR) occurred in one patient, partial response (PR) in 20 (CR + PR 53%), stable in eight, progression in 11 and five were unevaluable for response. The median relapse-free survival for responders was 25 weeks and median survival for all patients was 31 weeks. The mean dose intensity relative to the Cooper regimen fell from 1.02 to 0.6 within the first 4 weeks of treatment and the median dose intensity achieved for all patients on study was only 0.52. Eighty-seven per cent of patients had treatment delays with a mean of 3.9 delays per patient and 71% had dose reductions. Neutropenia was the major toxicity with WHO grade 3 or 4 neutropenia (less than 1.0 x 10(9) l-1) in 62% of patients and three septic deaths while neutropenic. Dose-intense weekly CMFVP in this schedule cannot be delivered to previously untreated outpatients with advanced breast cancer.     

Prolonged remissions of metastatic breast cancer achieved with a six-drug regimen of relatively low toxicity

A combination of six chemotherapeutic agents was used to treat 30 women with unresectable metastatic carcinoma of the breast. In the first year five drugs (Cytoxan, methotrexate, 5-fluorouracil, vincristine, and prednisolone [CMFVP]) were given using a weekly schedule for administration of intravenous drugs. During the next year, a seven-week treatment cycle was introduced, with CMFVP given for four weeks, followed by an Adriamycin combination (Adriamycin, cyclophosphamide, and prednisone [ACP]) for three weeks and then the cycle repeated. Treatment was continued for three years or to time of relapse. Overall response rate was 66.7% (20/30). The median duration of response was 40 months and the median survival 39 months. Premenopausal women fared better than postmenopausal women with comparable response rates, duration of response and survival being 81.5%, 41 months, 56 months versus 50%, 20 months and 27 months. Of 16 premenopausal patients treated 7 achieved a complete response (CR) and, of these, 5 remained free of disease at 3 years. For these five individuals all treatment was then stopped. Disease recurred in two patients by five months but three remain disease-free after 43, 40 and 34 months, respectively without therapy. Toxicity was generally limited to heartburn and modest hair loss. This regimen appears to be more effective than those previously employed for metastatic breast cancer. However, comparative trials will be necessary to confirm its advantages.     

Cyclophosphamide, adriamycin and platinum (CAP) combination chemotherapy, a new effective approach in the treatment of disseminated breast cancer. Preliminary report

The prospective controlled Phase III clinical trial tested the therapeutic value of the cis-platinum-adriamycin-cyclophosphamide combination (CAP), compared with the combination including cyclophosphamide, methotrexate, 5-fluorouracil, vincristine and prednisolone (CMFVP), in untreated metastatic breast cancer. One hundred and twenty-three patients (greater than 2 cycles) were evaluated: 61 on the CAP, and 62 on the CMFVP schedule. An objective response (CR + PR) to CAP combination chemotherapy was achieved in 72% of patients (43/61), with a high rate (36%) of complete remissions. In terms of metastatic site, the response rate appeared to be particularly high in soft tissue and visceral organ (lung, liver) metastases. In the CMFVP group, an objective response was noted in 26 of 62 patients (42%), with 16% complete remissions. The difference in overall therapeutic response - and in the complete remission rate as well - was statistically significant to the advantage of the CAP regimen (P less than 0.01). The duration of remissions was 6-28 + months (means = 14) for the CAP, and 4-15 + months (mean = 9) for the CMFVP schedule. Toxic side effects were more pronounced in the CAP group, particularly myelosuppression, with anemia prevailing. Side effects of CMFVP treatment were moderate. In 39 CMFVP previously treated cases, CAP was administered as second-line treatment, and an objective response was observed in 51% of cases (20/39). Results of this controlled trial showed the advantage of the CAP combination chemotherapy in the treatment of metastatic breast cancer.     

The effects of multiple combination chemotherapy with vincristine,cyclophosphamide (Endoxan), methotrexate, 5-fluorouracil,adriamycin and prednisolone (VEMFAH) for advanced breast cancer

Thirty-eight patients with advanced breast cancer were treated with the 'VEMFAH' multiple-drug combination chemotherapy, consisting of vincristine (V), cyclophosphamide (Endoxan; E), methotrexate (M), 5-fluorouracil (F), adriamycin (A), and prednisolone (H). Disease response was evaluated by the UICC criteria. Among the 35 evaluable cases, 4 complete responses (CR), 23 partial responses (PR), 2 cases of no change (NC), and 6 of progressive disease (PD) were observed. The response rate (CR + PR) was 77.1%. The median duration of response was 52 weeks (8-192 weeks) or 12 months. In 32 patients who received more than two courses of therapy the 50% survival time of responders was 27.0 months, which was significantly longer than the 10.3 months of nonresponders (P less than 0.05). Except for 2 patients who developed myocardial damage, the therapy was never terminated because of side effects. Cumulative cardiotoxicity was not apparent in this study. This multiple-drug combination chemotherapy with 'VEMFAH' is concluded to be an effective treatment for advanced and disseminated breast cancer.     

Adriamycin,vinblastine and mitomycin C as second-line chemotherapy in advanced breast cancer

Summary Thirty-six evaluable patients with metastatic measurable breast carcinoma previously treated with CMF or CMFVP were given second-line chemotherapy with Adriamycin, vinblastine, and mitomycin C (AVM), as follows: Adriamycin 20 mg/m² and vinblastine 6 mg/m² by i. v. push on days 1, 8, and 15, and mitomycin C 10 mg/m² i. v. on day 1, every 6 weeks. Ten patients (28%) achieved partial remission (PR) lasting a median of 10 months, and eight patients (22%) experienced improvement of a lesser level than PR. An additional nine patients (25%) had disease stabilization; in the remaining nine patients (25%), persistent disease progression was observed. The median survival from the onset of AVM was 7 months for all patients; patients with PR survived a median of 13 months.Myelotoxicity was substantial and frequently interfered with the optimal administration of AVM, especially in patients with skeletal metastases; four patients were hospitalized with leukopenia and fever; all recovered promptly; one death was probably related to thrombocytopenia and CNS bleeding.Our results with AVM are similar to the average response rate published in the literature with the use of Adriamycin as a single agent in previously treated patients with advanced breast cancer.

CAP (cyclophosphamide,adriamycin, platinum) vs CMFVP (cyclophosphamide,methotrexate, 5-fluorouracil,vincristine, prednisolone) combination chemotherapy in untreated metastatic breast cancer

Summary The prospective controlled phase III clinical trial compared the therapeutic value of the cis-platinum — adriamycin — cyclophosphamide combination (CAP) and that of the combination of cyclophosphamide, methotrexate, 5-fluorouracil, vincristine, and prednisolone (CMFVP) in untreated metastatic breast cancer. Seventy-two patients (>2 cycles) were evaluated: 36 had received CAP and 36, CMFVP. An objective response (CR+PR) to CAP combination chemotherapy was achieved in 75% of patients (27 of 36), with a high rate (42%) of complete remissions. In terms of metastatic site, the response rate appeared to be particularly high in soft tissue and visceral organ (lung, liver) metastases. In the CMFVP group, an objective response was noted in 16 of 36 patients (44%) with 19% complete remissions. Overall therapeutic response and the complete remission rate were better with CAP regimen (statistically significant; P<0.01). The duration of remissions was 4–16+months (M=12) for CAP and 2–12+months (M=8) for CMFVP. Toxic side-effects were more pronounced in the CAP group, particularly myelosuppression, and anemia was prevalent. Side-effects of CMFVP treatment were mild. In 11 CMFVP-resistant cases CAP was administered as second-line treatment, and an objective response was observed in 45% of cases (5 of 11). The preliminary results of this controlled trial show the advantage of the CAP combination in the treatment of metastatic breast cances.     

Evaluation of high-dose versus standard FAC chemotherapy for advanced breast cancer in protected environment units: a prospective randomized study

Fifty-nine evaluable patients under 65 years of age with measurable metastatic breast cancer and without prior chemotherapy were randomly assigned to treatment with fluorouracil, Adriamycin (Adria Laboratories, Columbus, OH), and cyclophosphamide (FAC) at standard or high doses (100% to 260% higher than standard FAC) following a dose escalation schedule. Patients randomized to the high-dose FAC received the first three cycles of therapy within a protected environment. Subsequent cycles for this group were administered at standard doses of FAC in an ambulatory setting, the same as for the control group. After reaching 450 mg/m2 of Adriamycin, patients in both groups continued treatment with cyclophosphamide, methotrexate, and fluorouracil until there was disease progression. Analysis of pretreatment patient characteristics showed an even distribution for most known pretreatment factors, although the control group had slightly (but nonsignificantly) more favorable prognostic characteristics. Fourteen patients (24%) achieved a complete remission (CR) and 32 (54%) achieved a partial remission (PR), for an overall major response rate of 78%. There were no differences in overall, CR, or PR rates between the high-dose FAC and control groups. The median response durations were 11 and 10 months for the protected environment and control groups, respectively, and the median survival was 20 months for both groups. Hematologic, gastrointestinal (GI), and infection-related complications were significantly more frequent and severe in the group treated with high-dose chemotherapy. Stomatitis, diarrhea, and skin toxicity were dose-limiting. However, there were no treatment-related deaths. High-dose induction combination chemotherapy with the agents used in this study failed to increase the response rate or survival duration, and resulted in a substantial increase in toxicity.     

VP-16 and adriamycin in patients with advanced breast cancer

Twenty-eight patients with advanced adenocarcinoma of the breast were treated with a combination of VP-16 and adriamycin (VAD). Two complete (CR), and eight partial (PR) remissions were observed. The CR plus PR produced a 36% response rate in this study. Nine additional patients had stable disease for at least 2 months. No drug deaths were seen with this combination, but thrombocytopenia, leukopenia, and vomiting were observed. Alopecia was seen in 100% of the patients treated with the above combination. This study suggests that the combination of adriamycin and VP-16 may be a good second-line therapy for patients with adenocarcinoma of the breast who failed and/or relapsed to CMFVP.     

Combination chemotherapy of advanced breast cancer. Comparison of dibromodulcitol, doxorubicin, vincristine, and fluoxymesterone to thiotepa, doxorubicin, vinblastine, and fluoxymesterone: an Eastern Cooperative Oncology Group Study

Two Adriamycin (doxorubicin)-based chemotherapy regimens were investigated in patients with carcinoma of the breast who had failed prior systemic therapy. The two chemotherapy programs, dibromodulcitol, Adriamycin, vincristine, and Halotestin (fluoxymesterone) (DAVH), and thiotepa, Adriamycin, vinblastine, and Halotestin (TAVH), were chosen for comparison on the basis of reported response rates of 40% to 50% with remission durations of 11 months in patients refractory to other cytotoxic chemotherapy. Cycles of DAVH were repeated every 4 weeks. Cycles of TAVH were repeated every 3 weeks. Of 184 patients evaluable for response, 32% of patients treated with DAVH and 38% of patients treated with TAVH had a complete response (CR) or partial response (PR). An additional 5% of patients had nonmeasurable improvement in osseous disease for an overall rate of response (CR + PR + improvement) of 40%. Patients who had previously received cytotoxic chemotherapy for metastatic disease or had early failure after adjuvant therapy had a lower response rate to DAVH, but not to TAVH than those who did not fail prior chemotherapy. Duration of response and survival were similar with the two treatments. There were seven treatment-related deaths, five among patients receiving DAVH and two among patients receiving TAVH. Patients receiving DAVH had significantly more thrombocytopenia and neurologic toxicity than those receiving TAVH. These treatments appear to be reasonable second-line regimens and are good candidates to be used in initial therapy of metastatic disease or adjuvant therapy studies that explore the use of alternating non-cross-resistant combinations with cyclophosphamide, methotrexate, and 5-fluorouracil.

Four-drug sequential regimen in advanced breast cancer

Summary The results of two empirically designed and potentially non-cross-resistant combinations administered sequentially in advanced breast cancer with the intent of achieving a high rate of durable complete remissions were analyzed. The two drug combinations consisted of cyclophosphamide plus Adriamycin and high-dose methotrexate plus cisplatin given for a total of three cycles; twenty evaluable patients, not previously treated with chemotherapy, were entered into the study. Ten patients were allocated to receive cyclophosphamide and Adriamycin first followed by high-dose methotrexate and cisplatin, while the remaining patients received the opposite sequence. The overall response rate for the entire group was 85% (17 of 20). However, only three of 20 (15%) patients achieved complete remission. One additional complete response was observed when treatment was prolonged for an additional complete cycle. The overall median duration of response was 13 months (range, 5–20⁺ months). Responses were similarly distributed among different sites of lesions. Myelosuppression and gastrointestinal toxicity were mild and transient. Reversible acute renal failure was observed after methotrexate administration in three cases. Present results indicate that overall this sequential treatment appears effective in patients with advanced breast cancer. However, the lack of an increased complete remission rate over conventional regimens coupled with a potential risk of renal toxicity prevents further studies with this multiple drug combination.     

A comparison of cyclophosphamide, adriamycin, 5-fluorouracil (CAF) and cyclophosphamide, methotrexate, 5-fluorouracil, vincristine, prednisone (CMFVP) in patients with metastatic breast cancer: a Southeastern Cancer Study Group project.

In an ongoing prospective randomized study, 113 evaluable patients have received either a three-drug combination that included cyclophosphamide, Adriamycin and 5-fluorouracil (CAF) or a five-drug combination including cyclophosphamide, methotrexate, 5-fluorouracil, vincristine and prednisone (CMFVP) given intermittently 1 week out of 4. Responses (64%), median duration of response (32 weeks), and median duration of disease control (32 weeks) achieved with CAF were superior to those achieved with CMFVP (37%, 22 weeks, 17 weeks, respectively). Morbidity secondary to CAF was significant, with nausea and vomiting, malaise, total alopecia, and granulocytopenia being the main features.     

Long-term follow-up results of a Pilot Phase II study of multidrug chemotherapy (MVP-CAB) in patients with advanced urothelial cancer.

BACKGROUND: To determine the long-term effects and toxicity of multidrug chemotherapy for advanced urothelial cancer. METHODS: Forty patients with metastatic urothelial cancer were treated with a new combination chemotherapy, MVP-CAB (methotrexate, doxorubicin, vincristine, cyclophosphamide, bleomycin and cisplatin every 28 days). Of the 40 patients, 26 had not undergone prior chemotherapy or radiotherapy; the remaining 14 patients had undergone prior cisplatin-based chemotherapy. RESULTS: The clinical response rate to MVP-CAB therapy for all 40 patients was 63% [complete response (CR), six patients; partial response (PR), 19 patients]. The median duration of the effects was 22 and 13 months in the patients with CR and PR, respectively. The clinical response rate for the 26 patients without prior chemotherapy was 77% (CR, four patients; PR, 16 patients). The rate for the 14 patients with prior chemotherapy was 36% (CR, two patients; PR, three patients). The response rate according to metastatic site was highest for the liver (80%), followed by the lymph nodes (74%) and lungs (67%). The effect on bone metastasis was poor (22%). There was good compliance with the MVP-CAB chemotherapy regimen and toxicity was tolerable. The 1-, 3- and 5-year overall survival rates were 42.5, 10 and 5%, respectively. CONCLUSIONS: MVP-CAB combination chemotherapy was found to be effective for the treatment of advanced urothelial cancer, especially for liver metastasis.     

The effect of dose intensity on M-VAC therapy for advanced urothelial cancer

M-VAC therapy (methotrexate, vinblastine, Adriamycin, and cisplatin) has improved the treatment results of urothelial cancer patients. However, it is sometimes complicated by drug toxicities, including bone marrow suppression. We analyzed the relative dose intensity in each patient undergoing M-VAC chemotherapy in relation ot the chemotherapeutic effect and survival. In addition, the role of granulocyte colony-stimulating factor (G-CSF) in the dose intensity of M-VAC therapy was analyzed. Between June 1988 and March 1993, 29 patients with advanced urothelial cancer were treated with M-VAC therapy in our institution. Of 18 patients with evaluable lesions, 2 (11.1%) showed a complete response (CR) and 7 (38.9%) showed a partial response (PR), and the overall response rate was 50.0%. The median follow-up period for these 18 patients was 14.6 months and the median survival was 8.7 months, with 12 of the 18 patients being alive at the time of analysis. The relative dose intensity (RDI) for these 18 patients was 0.81 for methotrexate, 0.80 for vinblastine, 0.92 for Adriamycin, and 0.91 for cisplatin, for a mean RDI of 0.87. There was no correlation between the chemotherapeutic effect and the RDI. When we calculated the RDI for all 29 patients who underwent M-VAC therapy, G-CSF increased the RDI of Adriamycin significantly. The results of this retrospective study indicate that a dose intensity for M-VAC therapy in the range of 0.61–1.00 is unlikely to correlate with the chemotherapeutic effect, although G-CSF contributes to increasing the RDI of Adriamycin.Paper presented at the 5th International Conference on Treatment of Urinary Tract Tumors with Adriamycin/Farmorubicin, 24–25 September 1993, Hakone, Japan     

Sequential methotrexate-5-fluorouracil (MTX-5-FU) treatment of patients with advanced gastric and colorectal cancer. Sequential Methotrexate-5-FU Study Group

A multicenter cooperative study was conducted from July 1984 to March 1986 to evaluate the clinical efficacy of sequential MTX-5-FU treatment in 96 cases of advanced gastric cancer and 39 cases of colorectal cancer. 5-FU 600 mg/m2 i.v. was given and MTX 30 mg/m2 (A), 100 mg/m2 (B) and 300 mg/m2 (C) i.v. were given, and the administration interval between MTX and 5-FU was 1 to 3 h for the gastric cancer group, and 7 h for the colorectal cancer group. Leucovorin rescue of 10 mg/m2 p.o. was given 24 h after MTX administration. In the gastric cancer group, the response rate for Regimen A was 23.2% (CR 1 and PR 12) out of 56 evaluable cases, and for Regimen B, 40.5% (CR 1 and PR 14) out of 37 evaluable cases. In the colorectal cancer group, the response rate for Regimen A was 28.6% (PR 6) out of 21 evaluable cases and for Regimen B, 20.0% (PR 3) out of 15 cases. Median survival time for the gastric cancer group was 5.5 months with Regimen A and 7.6 months with Regimen B, and for the colorectal cancer group 10.9 months with Regimen A and 7.9 months with Regimen B. Main adverse effects were marrow impairment and gastrointestinal symptoms such as nausea, diarrhea, and stomatitis. In this study Regimen B showed relatively good results. In order to evaluate the biochemical modulation occurring with sequential MTX-5-FU treatment, a further phase III study in gastric cancer patients should be conducted.     

Chemotherapy versus chemoimmunotherapy in advanced adenocarcinoma of the colon and rectum: a prospective randomized study.

The combination of vincristine, methyl-CCNU, and methotrexate with or without MER-BCG achieved a 2% complete response (CR) and a 11% partial response (PR) with a median duration of 25-29 weeks in 124 evaluable patients with advanced adenocarcinoma of the colon and rectum. Responses were seen in previously untreated patients and in patients refractory to 5-fluorouracil. The median survival of these objective responders (CR + PR) was 57 weeks. The addition of MER-BCG did not appear to influence response rate or duration of survival and was accompanied by significant toxicity. Response was significantly correlated with performance status, sex, and disease free interval and survival with alkaline phosphatase and performance status. Patients with advanced colorectal carcinoma should be stratified according to these variables.
