Salvage chemotherapy in Hodgkin's disease. Results in patients relapsing more than twelve months after first complete remission.

Forty-nine patients with Hodgkin's disease who relapsed after a first complete remission of more than 12 months following primary chemotherapy were treated with salvage therapy regimens. A total of 41 patients (84%) achieved complete remission. In particular, complete response was documented in 17 of 19 patients re-treated with the same initial drug combination. The five-year freedom from progression, relapse-free and overall survivals were 51%, 57% and 65%, respectively. In our experience, consolidation radiotherapy following drug-induced remission failed to improve the five-year relapse-free survival. Present findings indicate that about half of patients relapsing after a disease-free interval exceeding 12 months can remain alive and disease-free 5 years after starting salvage chemotherapy.

Randomized trial of chemotherapy versus chemotherapy plus radiotherapy for stage III-IV A & B Hodgkin's disease.

A total of 151 patients with previously untreated Hodgkin's disease, clinical stages III-IV A & B, were randomized to receive CVPP for 6 cycles, or CVPP plus RT 3000 cGy to previously involved areas between the 3rd and 4th cycles. CVPP consists of cyclophosphamide 600 mg/m2/i.v., vinblastine 6 mg/m2/i.v. on day 1, procarbazine 100 mg/m2/p.o. and prednisone 40 mg/m2/p.o. on days 1 to 14. Both groups displayed similar clinical characteristics at diagnosis. Sixty-six were treated with CVPP + RT (52 St III and 14 St IV) and 85 with CVPP alone (68 St III and 17 St IV). Complete remission was obtained in 57 (86%) of 66 patients who received CVPP plus RT, and in 62 (73%) of 85 patients treated with CVPP. Five and sixteen patients, respectively, achieved partial responses, while 2 in each group died during treatment. At 7 years, duration of complete remission and failure-free survival were: 51% and 45% for those treated with CVPP plus RT, and 23% and 21% with CVPP alone (p = 0.0150 and P = 0.0016, respectively). Overall survival at 7 years was 71% and 58%, respectively (p = 0.1488). A dose analysis performed in 84 pts showed that 91% and 88% received full protocol doses of CPM and PCZ, respectively, in the CVPP + RT group, and 95% and 94% for CVPP. The WBC nadir was 3.5 and 3.7 x mm3, respectively. Of 25 pts on CVPP + RT who relapsed, 9 are now disease-free, 5 are alive with disease and 11 have died, and with CVPP, of 37 relapsing pts, 18 are disease-free, 5 are alive with disease and 14 are dead.(ABSTRACT TRUNCATED AT 250 WORDS)

Long term response to chemotherapy in patients with visceral metastatic melanoma.

PATIENTS AND METHODS: Eight patients who remain in long term remission 4 to 15 years after chemotherapy for visceral metastatic melanoma are described. These patients were observed among some 1100 patients with visceral melanoma seen at the Sydney Melanoma Unit between 1977 and 1989. Only about one-third of such patients received chemotherapy, almost always with single agent dacarbazine or a nitrosourea. RESULTS: The apparently cured patients did not differ from the overall group of patients with visceral metastases in baseline characteristics, but 6 of the 8 had nodular lung metastases. CONCLUSIONS: While the mechanism remains uncertain, one possibility could be that chemotherapeutic agents cause mutations which allow expression of antigenicity in tumour cells. In any case, the fact of occasional exceptionally good responses, perhaps amounting to cure, constitutes an argument for a trial of chemotherapy in patients with visceral metastatic melanoma.

Results of CAV regimen (CCNU, melphalan, and VP-16) as third-line salvage therapy for Hodgkin's disease.

BACKGROUND: A prospective study was conducted to assess the efficacy and toxicity of a salvage regimen consisting of CCNU, Melphalan, and VP-16 (CAV) given at 28-day intervals in patients with Hodgkin's disease (HD) relapsing after primary therapy or refractory to the alternating MOPP/ABVD regimen. PATIENTS AND METHODS: This study included 58 patients (median age: 34 years), with resistant or relapsing HD. Primary therapy had consisted of alternating MOPP/ABVD (81%) or MOPP alone (19%); 38% of patients were relapsing from prior complete remission (CR) while 62% had resistant disease. Extranodal disease was present in 55% and B-symptoms in 72% of patients; one-fifth had bulky disease and/or bone marrow involvement. The CAV was used as first salvage in half of the patients. RESULTS: Complete remission was obtained in 17 patients (29%); unfavorable factors for CR in univariate analysis were the presence of bulky disease and the failure to achieve CR with prior therapy. Nine patients (53% of remitters) have subsequently relapsed with a 10-month median duration of CR. The 3-year overall survival after CAV was 25% with an 18-month median survival; significant differences in survival were found according to the extent of disease, the presence of B-symptoms and the HD status (prior sensitive or resistant disease, first or subsequent relapse). Seven patients are long-term remitters (12%), and one of them has been given high-dose chemotherapy and autologous bone marrow transplantation at relapse after CAV. The CAV toxicity was mostly hematological; severe pancytopenia occurred in six cases with two cases of fatal infections and one of fatal hemorrhage. CONCLUSION: CAV therapy was moderately effective as third-line salvage in patients with HD resistant to alternating MOPP/ABVD or previously given two different regimens for relapse; the toxicity was mostly hematological and supportive therapy was needed in one-third of the patients.

Early versus late alternating chemotherapy in small-cell lung cancer. Swiss Group for Clinical Cancer Research (SAKK).

BACKGROUND: From 1984 to 1989, the Swiss Group for Clinical Cancer Research (SAKK) performed a randomized phase III trial comparing early versus late alternating chemotherapy in patients with small-cell lung cancer. PATIENTS AND METHODS: 406 eligible patients were entered into the trial. Regimen A consisted of PAV (cisPlatin, Adriamycin, VP 16-213, and Regimen B of CyMOC (Cyclophosphamide, Methotrexate, Oncovin, CCNU). Cycles were repeated as rapidly as possible. patients were randomized to receive either ABABAB (early alternating chemotherapy) or AAABBB (late alternating chemotherapy). After six cycles patients with limited disease in complete or partial remission and those with extensive disease in complete remission received irradiation to the primary (45 Gy) and the CNS (36 Gy). RESULTS: The overall remission rate was 87% with 31% complete remissions. The median survival of all 406 eligible patients was 346 days with 15% of the patients alive at two years. The overall remission rate, the rate of complete remission, the median survival and the rate of long-term survival were not significantly different in the two treatment arms. In limited disease the estimated percentages of survival at 2 years were 33% in the early and 24% in the late alternating chemotherapy arms. Patients with extensive disease survived significantly longer with late alternating chemotherapy than on the early alternation regimen (median survival 336 days versus 301 days, p = 0.01). In the latter patients the received dose intensities (RDI) of cisplatin, adriamycin and etoposide were significantly higher in the late-alternation arm. Patients treated with early alternating chemotherapy rated their tumor symptoms, functional states, fatigue/malaise and restriction of social activity significantly better, reflecting an improved subjective adjustment. CONCLUSIONS: Alternating chemotherapy with PAV-CyMOC plus consolidating radiotherapy is a feasible and effective treatment for small-cell lung cancer, with acceptable toxicity. Whereas patients with early alternating chemotherapy achieve a better subjective adjustment, late alternating chemotherapy allows for a higher RDI of cisplatin, adriamycin and etoposide, which results in a significantly longer median survival of patients with extensive disease.

Further chemotherapy versus low-dose involved-field radiotherapy as consolidation of complete remission after six cycles of alternating chemotherapy in patients with advance Hodgkin's disease. German Hodgkins' Study Group (GHSG).

OBJECTIVE: It was the aim of this prospective randomized multicenter study to compare chemotherapy and radiotherapy as consolidation treatments in patients achieving complete remission (CR) after 6 cycles of doxorubicin-containing chemotherapy in advanced-stage Hodgkin's disease (HD). METHODS: A total of 288 previously untreated patients aged 18-60 years with stage IIIB or IV HD received induction chemotherapy with 3 X (COPP + ABVD). Patients achieving CR were eligible for randomisation to either 20 Gy radiotherapy to initially involved fields (RT-arm) or to an additional 1 X (Copp + ABVD) (CT-arm ). Patients with nodal PR were allocated to more intense radiotherapy (IRT-arm: 20 Gy IF, 40 Gy to persisting tumor). Four patients with persisting organ involvement after induction received salvage chemotherapy. RESULTS: Of 288 patients, 171 (59%) achieved CR after induction chemotherapy. Of these, 100 patients were successfully randomized to RT or CT. In the CT arm relapses were observed on 10 of 49 patients compared with 13 of 51 patients in the RT arm (p = n.s.). Fifty patients refused randomisation and for them a treatment was chosen, and 21 patients refused any further treatment. Of these 21 patients with no consolidation therapy, 9 relapsed, indicating an approximately 3-fold increased relapse risk compared with those receiving either of the consolidation therapies. No relapse was observed in initially involved lung or liver sites. Adverse prognostic factors for freedom from treatment failure and survival were low hemoglobin and large mediastinal mass at initial presentation. CONCLUSIONS: No statistically significant differences in treatment efficacy were detected between 20 Gy IF radiotherapy and 1X (COPP + ABVD) chemotherapy following CR after six cycles of alternating chemotherapy in patients with advanced-stage HD. However, limited observations in a non-randomized cohort indicate that patients without consolidation treatment of CR after 6 cycles of chemotherapy may have an elevated risk of relapse.

Mitomycin-C, etoposide, cisplatin, and hexamethylmelamine (MEPH) as a second-line regimen in lung cancer.

Fifty-three patients with advanced lung cancer refractory to chemotherapy with MACC (methotrexate, adriamycin, cyclophosphamide, and CCNU) were treated with a combination of mitomycin-C, etoposide, cisplatin, and hexamethylmelamine (MEPH). Among 45 evaluable patients, there were seven partial responders (16%), including 2/18 adenocarcinomas, 3/13 small cell anaplastic carcinomas, 1/5 large cell anaplastic carcinomas, and 1/9 squamous cell carcinomas. Major toxic side effects included thrombocytopenia (30/45 patients), leukopenia (22/45 patients), and emesis. Renal toxicity occurred in three patients, and cardiac arrhythmia was observed in one patient. Despite a low response rate, which was expected in this group of heavily pretreated patients with poor prognostic characteristics, these data suggest a lack of cross-resistance between MEPH and MACC.

Combination chemotherapy with 5-fluorouracil, CCNU, and vincristine in metastatic colorectal carcinoma.

Twenty-four patients with metastatic colorectal carcinoma were treated with a chemotherapeutic regimen consisting of 5-fluorouracil, CCNU, and vincristine (FCV). Twenty patients were evaluable for response and 22 were evaluable for drug toxicity. One patient (5%) showed partial response, eight patients (40%) had stabilization of disease, and the remaining 11 patients (55%) had progression of disease. There was no statistically significant difference between the median survivals of patients with stabilization and of those with progression of their disease (p greater than 0.01). We were unable to demonstrate objective efficacy of the FCV regimen in the schedule used.

Adjuvant chemotherapy of malignant melanoma. A pilot study.

In a pilot study, 26 patients with stage I malignant melanoma, tumor thickness greater than 2.25 mm, and/or Clark level IV, and Stage II tumors were randomized to adjuvant chemotherapy with either DTIC, DTIC/CCNU/vincristine, or to a control group with no further treatment after surgery. The chemotherapy group contained 17 patients and the control group nine patients. The follow-up time is 37-54 months. The recurrence-free and overall survival is significantly longer in the patient group treated with adjuvant chemotherapy as compared to controls (p less than 0.025, according to the log-rank test).

Failure of combination chemotherapy of advanced follicular (low-grade) non-Hodgkin's lymphoma.

Twenty-two patients with Stage III and IV follicular non-Hodgkin's lymphoma were treated for 8 months by a chemotherapy regimen alternating between two different four-drug combinations (doxorubicin, teniposide, cyclophosphamide, prednisone; vincristine, cyclophosphamide, CCNU, prednisone). The overall response rate (complete and partial remission) was 68%. The complete remission rate was 23%. Twenty patients are alive, 50% of them are free of disease progression (median follow-up 76 months). It is concluded that our chemotherapy regimen is not satisfactory and that new therapeutic approaches are needed.

Evaluation of CCNU and misonidazole in the treatment of advanced colorectal cancer.

Eighteen adult colorectal cancer patients, previously untreated with systemic chemotherapy, were given CCNU and MISO. One patient had an excellent partial response of pulmonary metastases, but the overall response rate was only 6%. Gastrointestinal toxicity was modest, hematologic toxicity was similar to what would have been predicted for CCNU alone, and there was no neurotoxicity detected. This Phase II study demonstrates that these two agents can be administered safely, but have no advantage over CCNU alone.

Alternating chemotherapy with or without VP-16 in extensive-stage small-cell lung cancer.

In this study, we evaluated the role of alternating chemotherapy with or without etoposide (VP-16) in patients with extensive-stage small-cell carcinoma (SCC) of the lung. All patients received initial treatment with CMC [cyclophosphamide, methotrexate, and chloroethyl-cyclohexyl-nitrosourea (CCNU)]. Four weeks after initial treatment, patients were stratified by performance score, central nervous system (CNS) metastasis, age, and response to initial CMC therapy and randomized to receive AO (doxorubicin and vincristine) or AVO (doxorubicin, VP-16, and vincristine) alternating with CMC. One hundred eighty-two eligible patients were treated with the initial cycle of CMC and 98 responded (54%). One hundred fifty-four patients were randomized to either AO/CMC or AVO/CMC. The response rates to AO/CMC and AVO/CMC were similar (72 vs. 68%). The time to progression and survival were not significantly different on the two treatment regimens. Toxicity was significantly greater for patients receiving AVO/CMC with six treatment-related deaths. Etoposide as used in this regimen did not significantly influence response rates, time to progression, or survival of patients with extensive small-cell lung cancer.

Non-small-cell lung cancer (NSCLC): chemotherapy in advanced disease. Our experience in ten years.

This is a review of the therapeutic schedules used in our service during the past 10 years for the therapy of advanced non-small-cell lung cancer. During the first years, nonrandomized trials were conducted and several combinations were tested: MACC (methotrexate, doxorubicin, cyclophosphamide, and CCNU), cisplatin-etoposide, and cisplatin-vindesine. The results of these trials were invariably discouraging: objective responses hardly reached 30%, while the survival was around 15 months in the best case. On December 1985 a new randomized trial, based on the combination MIP (mytomicin, ifosfamide, cisplatin) was designed; 60.7% of objective responses were achieved, with 9 complete remissions (17.6%) and 22 partial remissions (43.1%). Median survival was 15 months. In order to reduce the toxicity of this combination, carboplatin was substituted for cisplatin. Unfortunately, results were very poor. No complete remission, and only 5 partial responses (20%) were achieved. At the present time, a new randomized trial is being conducted. In it, MIP combination is compared with VIP (vindesine, ifosfamide, cisplatin). Preliminary results have shown no differences between both arms in response, toxicity, or survival. New therapeutic approaches, as neoadjuvant therapy, are being explored.

A randomized clinical trial in bronchogenic small-cell carcinoma evaluating alternating maintenance therapy of vincristine, adriamycin, procarbazine, and etoposide (VAPE) with cyclophosphamide, CCNU, and methotrexate (CCM) versus CCM maintenance alone in complete responders following VAPE induction and late intensification.

Initially, 109 evaluable patients with locally advanced or metastatic small cell lung cancer (SCLC) were treated with vincristine, Adriamycin, procarbazine, and etoposide (VAPE). Partial (PR) or nonresponders (NR) were crossed to CCM (cyclophosphamide, CCNU, and methotrexate) and then to HMiVe (hexamethylmelamine, mitomycin C, vinblastine) sequentially at maximum response. Complete responders (CR) were intensified by 50% with VAPE primarily and randomized to VAPE, alternating with CCM or CCM alone during maintenance. CR patients with limited disease received local thoracic irradiation and prophylactic cranial irradiation (PCI), whereas those with extensive disease received PCI alone. There were 45 patients (41%) who achieved a CR to chemotherapy, and 27 patients were eligible for randomization. Of 12 CR patients randomized to alternating therapy (VAPE/CCM), the median survival was 25.9 months compared to 12.9 months for 15 CR patients randomized to continuous CCM (P = .049). In addition, 35 patients achieved a PR (32%) and 29 were NR (27%). Overall median survivals were significantly different for the CR patients (13.0 months) as compared to PR (7.6 months) and NR patients (6.4 months). Late intensification did not appear to add substantially to survival while contributing to toxicity. In summary, VAPE is a new outpatient regimen for SCLC, which is highly effective as an induction regimen with moderate hematologic toxicity and predominantly gastrointestinal nonhematologic toxicity.

Follicular thyroid carcinoma: response to chemotherapy.

A 69-year-old woman with far advanced inoperable follicular carcinoma of the thyroid became refractory to radioactive iodine therapy and to combination chemotherapy with adriamycin and cyclophosphamide. She then attained a good clinical response to chemotherapy with adriamycin, CCNU and methotrexate (ACMe); this lasted more than a year. The regimen of adriamycin, CCNU, and methotrexate deserves further study for patients with follicular thyroid carcinoma.

The prognosis of melanoma patients with metastases to two or more lymph node areas.

The prognosis of melanoma patients who present with metastatic involvement of two or more noncontiguous lymph node regions before the detection of extranodal metastases has not been previously reported. We identified 21 patients with metastatic melanoma in at least two nodal basins in a review of 175 patients with melanoma undergoing lymphadenectomy at the National Cancer Institute. The median survival time of these patients was 46 months, with 55%, 27%, and 17% of the patients alive 2, 5, and 10 years, respectively, after the second lymphadenectomy. Because the prognosis of melanoma patients with metastases to two or more regional nodal areas appears equivalent to that of patients with metastatic involvement of only one regional node site, lymphadenectomy of the involved groups should be performed with therapeutically curative intent.
