Oligodendroglial tumor chemotherapy using "decreased-dose-intensity" PCV: a Singapore experience.

The authors propose "decreased-dose-intensity" PCV (procarbazine, lomustine [CCNU], and vincristine) chemotherapy for Asian patients with oligodendroglial tumors. In this study, all seven patients with oligodendroglioma (OD) and eight with anaplastic oligodendroglioma (AO) had objective responses or stable disease. Median progression-free survival was greater than 29 months (OD) and 36.5 months or greater (AO); 86% of patients with OD and 63% with AO remain progression-free. Twenty-four Common Toxicity Criteria Grade 3/4 adverse events were noted.

PCV chemotherapy for recurrent glioblastoma.

The authors administered procarbazine, 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea (CCNU, lomustine), and vincristine (PCV) to 86 patients with recurrent glioblastoma. There were three partial responses, but no complete responses. Median progression-free survival was 17.1 weeks and progression-free survival at 6 months was 38.4%. World Health Organization grade III/IV hematologic toxicity was common (25.6%), but nonhematologic toxicity was mild.

Low-grade oligodendroglioma responds to chemotherapy.

We administered chemotherapy in standard and intensified formulations of procarbazine, lomustine (CCNU), and vincristine to nine symptomatic patients with low-grade oligodendroglioma. Eight patients were treated with chemotherapy at presentation and one was treated for a recurrence after radiotherapy had failed. All patients improved by clinical or MRI criteria, or both. No patient deteriorated while in therapy and the responses were sustained without radiotherapy for a median of 35 months (range, 22-45) in all surviving patients treated at presentation. Chemotherapy was well tolerated; all patients developed myelosuppression, but only those receiving the intensified regimen required dose reduction or premature discontinuation of treatment. As with recurrent and anaplastic oligodendroglioma, low-grade oligodendroglioma responds to chemotherapy.

Response rate and prognostic factors of recurrent oligodendroglioma treated with procarbazine, CCNU, and vincristine chemotherapy. Dutch Neuro-oncology Group.

OBJECTIVES: To determine the response rate and factors correlated with response of oligodendroglial tumors to procarbazine, lomustine (CCNU), and vincristine (PCV) chemotherapy. DESIGN: Retrospective, observational multicenter study. METHODS: Patients treated with PCV or intensified PCV chemotherapy for a recurrent oligodendroglial tumor after surgery and radiation therapy with measurable disease were retrospectively evaluated for response. A 50% reduction in cross-sectional enhancing tumor area was considered a partial response. Stabilized or responding patients received six cycles of PCV unless unacceptable toxicity occurred. RESULTS: Fifty-two patients were included; median time to progression (MTP) for the entire group was 10 months. In 17% of patients a complete response (MTP, 25 months) was obtained, and in 46% a partial response (MTP, 12 months) was obtained. Median overall survival was 20 months. Although treatment was discontinued for toxicity in seven patients, it was generally well tolerated. The intensified PCV regimen was more toxic. Patients initially presenting with seizures and patients with tumor necrosis in histologic specimens had a better response rate in contrast to patients who had their first relapse within 1 year of first treatment (surgery and radiation therapy). CONCLUSIONS: Oligodendroglial tumors are chemosensitive, but most patients will have relapsed after 12 to 16 months. New studies must aim at improving initial treatment and second-line chemotherapy.

Spinal cord astrocytoma: response to PCV chemotherapy.

Information regarding the value of chemotherapy for spinal cord astrocytomas that progress after irradiation is limited. We describe a patient whose conus medullaris astrocytoma responded to PCV (procarbazine, lomustine, and vincristine) chemotherapy after failing radiation and cisplatin-based chemotherapy. PCV should be considered in patients with progressive spinal cord astrocytomas.

PCV chemotherapy for recurrent glioblastoma multiforme.

The authors evaluated response, time to progression (TTP), survival, prognostic factors, and toxicity in 63 patients with a recurrent glioblastoma multiforme treated with procarbazine, lomustine, and vincristine (PCV) chemotherapy. Complete and partial response was observed in two (3%) and five patients (8%). In 16 patients (25%), stable disease was observed. Median TTP and survival were 13 and 33 weeks. Age < 40 years and Karnofsky Performance Status > or = 90 were associated with longer TTP and survival. PCV treatment was generally well tolerated.

High-dose chemotherapy with stem cell rescue as initial therapy for anaplastic oligodendroglioma: long-term follow-up.

We previously reported a phase 2 trial of 69 patients with newly diagnosed anaplastic or aggressive oligodendroglioma who were treated with intensive procarbazine, CCNU (lomustine), and vincristine (PCV) followed by high-dose thiotepa with autologous stem cell rescue. This report summarizes the long-term follow-up of the cohort of 39 patients who received high-dose thiotepa with autologous stem cell support. Thirty-nine patients with a median age of 43 (range, 18-67) and a median KPS of 100 (range, 70-100) were treated. Surviving patients now have a median follow-up of 80.5 months (range, 44-142). The median progression-free survival is 78 months, and median overall survival has not been reached. Eighteen patients (46%) have relapsed. Neither histology nor prior low-grade oligodendroglioma correlated with risk of relapse. Persistent nonenhancing tumor at transplant was identified in our initial report as a significant risk factor for relapse; however, long-term follow-up has not confirmed this finding. Long-term neurotoxicity has developed only in those patients whose disease relapsed and required additional therapy; no patient in continuous remission has developed a delayed neurologic injury. This treatment strategy affords long-term disease control to a subset of patients with newly diagnosed anaplastic oligodendroglioma without evidence of delayed neurotoxicity or myelodysplasia.

Survival following adjuvant PCV or temozolomide for anaplastic astrocytoma.

We compared survival in patients with anaplastic astrocytoma (AA) treated with adjuvant procarbazine, lomustine, and vincristine (PCV) with survival in patients treated with temozolomide. A retrospective analysis was made of patients with newly diagnosed AA treated with adjuvant postradiotherapy chemotherapy. Outcome analysis included progression-free survival and overall survival. The following prognostic factors were taken into account: patient age, extent of resection, performance status, presence of contrast enhancement in presurgical imaging, and type of adjuvant treatment. Among 109 AA patients, 49 were treated with PCV and 60 with temozolomide. The treatment groups were well matched for pretreatment characteristics, except for the presence of contrast enhancement. Age, extent of surgery, performance status, and presence of contrast enhancement were statistically significant prognostic factors according to the Cox model analysis of survival. Type of adjuvant chemotherapy was not a significant factor, either for progression-free survival or for overall survival. Hematological toxicity, nonhematological toxicity grades 3-4, and premature discontinuation due to toxicity were observed in 9%, 3% to 5%, and 37%, respectively, of cases in the PCV group versus 4% to 5%, 0, and 0, respectively, in the temozolomide group. Although the present study was not randomized, it was well designed, and it reports on two homogeneous and consecutive series of patients, for whom histology was verified to obtain survival data only for patients with AA following the recent WHO 2000 classification. Even if no survival advantage has been demonstrated for temozolomide versus PCV, we conclude that temozolomide should be preferred because of its greater tolerability.

Aggressive oligodendroglioma: a chemosensitive tumor.

Aggressive oligodendrogliomas, tumors that are symptomatic, enlarging, enhancing, and usually but not always anaplastic, respond to chemotherapy. We have observed responses to chemotherapy in 18 of 19 consecutively treated patients with newly diagnosed or recurrent aggressive oligodendrogliomas. A regimen of procarbazine, CCNU (lomustine), and vincristine (PCV) is predictably effective, but other drugs have antioligodendroglioma activity. Cooperative group trials will be necessary to determine the most effective drug, or combination of drugs, and to explore fully the role of chemotherapy in the treatment of this uncommon glioma.

Acquired cervical syringomyelia secondary to a brainstem meningioma in a maltese dog.

A 15-year-old female maltese was referred to us because of a 3-month history of ataxia, circling, and acute blindness. A mass was noted in the brainstem on brain magnetic resonance images. A cerebellar herniation was also detected on T1-weighted sagittal images. The lateral, third and fourth ventricles and central canal of the cervical spinal cord were enlarged. Based on diagnostic imaging findings, cervical syringomyelia secondary to a brainstem tumor was suspected. The clinical signs were controlled well by lomustine and the dog survived for 8 months after the initial diagnosis. The mass was diagnosed as a meningioma based on histopathological findings. This report describes the clinical findings and imaging characteristics of an acquired syringomyelia resulting from a brainstem meningioma.

Systemic chemotherapy in the treatment of malignant melanoma.

Different postsurgical therapies are used for the treatment of metastatic melanoma. This article reviews the use of chemotherapeutic agents in the treatment of patients with metastatic malignant melanoma. A variety of single chemotherapy agents have been evaluated, although the most widely used chemotherapeutic in the treatment of metastatic melanoma is dacarbazine. In order to improve the rate and duration of responses, combination chemotherapy was developed. The most common combined chemotherapy regimens used as standard for the treatment of metastatic melanoma are Dartmouth regimen, CVD (cisplatin + vinblastine + dacarbazine) and BOLD (bleomycin + vincristine + lomustine + dacarbazine). However, Phase III trials have failed to demonstrate a significant benefit in survival in patients treated with polychemotherapy compared to those treated with dacarbazine alone. The use of classical systemic chemotherapy still has a role in the treatment of patients with metastatic melanoma. Immunotherapy and biochemotherapy have no additional advantage over chemotherapy.

Radiation therapy for brain metastases from malignant melanoma.

Thirty-nine patients who completed whole-brain irradiation treatment for brain metastases from malignant melanoma were analyzed. Median survival was 2 months, mean survival 4 months. Only 3 patients survived for 1 year, the longest survival being 19 months after irradiation. Twenty-one (53.8%) showed marked clinical improvement and 6 (40%) of the 15 evaluable patients had some objective regression of the brain metastases. A treatment of 7 fractions of 4.8 Gy in 9 to 14 days and concomitant chemotherapy with dacarbazine and lomustine in 16 patients was well tolerated. This seems to be a beneficial treatment for patients with a comparatively small intracranial tumour burden.

Combination chemotherapy with a five-drug regimen for invasive thymoma.

Nine patients with stage III and stage IV thymoma were treated with cisplatin, vincristine, lomustine, cyclophosphamide and prednisolone. Two patients (22%) obtained remission, and four patients (44%) showed no change for 11 to 31 months. It was found that this five-drug regimen did not improve the results obtained by other chemotherapy modalities for thymoma.

Full chemotherapy in elderly patients with small cell bronchial carcinoma.

Data on small cell lung cancer (SCLC) in elderly patients with full chemotherapy are sparse. We present material of 345 patients treated with chemotherapy (CT) with no age limits. CT was given with 2 different types of 4-drug combinations, including cyclophosphamide, doxorubicin, vincristine, methotrexate, lomustine and etoposide. Radiotherapy 40 Gy was given to 85% of the limited disease (LD) and 15% of the extensive disease (ED) patients. In 345 consecutive SCLC patients (50% LD and 50% ED) with a median survival time (MST) of 10 months and a disease-free 5-year survival 3.8%. Multivariate analysis showed clear correlation between stage of disease and survival as well as between age and survival though less pronounced. One hundred and ten patients were > 70 years of age with a median survival time of 7.4 months (LD 12.3 and ED 4.6) and 235 patients < 70 years of age had a median survival time of 10.9 months (LD 14.4 and ED 7.5) and a disease-free 5-year survival of 5.1%. The survival differences were statistically significant. Treatment toxicity was higher in patients > 70 years of age. Seventy-seven patients 70-75 years of age had an MST of 9.5 months (LD 13.2 and ED 6.2) and a disease-free 5-year survival of 1.3%. The survival differences between patients 70-75 years old and those < 70 years of age were small but statistically significant in LD at 5% level but not in ED. There were more septicemias per courses CT given in all patients 70-75 years of age and also more lethal septicemias in ED patients. Patients with LD SCLC 70-75 years of age might benefit from full treatment in terms of median and long-term survival.

Attempted prevention of blast crisis in chronic myeloid leukemia by the use of pulsed doses of cytosine arabinoside and cis-chloronitrosurea during the course of busulfan-maintained remission.

We performed this chemotherapeutic trial to try to delay the onset of the blast crisis of chronic myeloid leukemia (CML) by pulsing doses of drugs most likely to be effective against emerging "blast" cells characteristic of acute phase disease. A randomized trial in patients with CML comparing busulfan maintenance to busulfan maintenance plus pulsed doses of cytarabine and lomustine did not yield any differences in either time to blast crisis or death.

Intrinsic brainstem choroid plexus papilloma. Case report.

The authors report an intrinsic brainstem lesion that was diagnosed initially as a pontine cavernoma, which finally proved to be a choroid plexus papilloma. Choroid plexus papillomas are rare tumors of the central nervous system and are usually intraventricular in location. The occurrence of this tumor in an intraparenchymal location is extremely rare, and its occurrence within the brainstem is previously unreported. The authors also report a trial of chemotherapy with lomustine in the management of the residual tumor.

Oral combination chemotherapy in the treatment of AIDS-associated Hodgkin's disease.

OBJECTIVES: To determine the effectiveness of an oral combination chemotherapy regimen administered to patients with AIDS-associated Hodgkin's disease. DESIGN: Prospective, pilot phase II clinical trial. SETTING: Consecutive patient recruitment occurred at two medical centers in the United States: Albany Medical Center, Albany, New York, where patients were recruited prior to December 31, 1996 (pre-HAART era); and University Hospitals of Cleveland, Cleveland, Ohio, where patients were recruited after January 1, 1997 (HAART era). INTERVENTION: Oral chemotherapy consisted of lomustine (100 mg/m2 day I for cycle one and odd cycles thereafter); etoposide (200 mg/m2 days 1 through 3); and cyclophosphamide and procarbazine (each 100 mg/m2 days 22 through 31). Cycles were repeated every six weeks. Colony-stimulating factor support (G-CSF in all instances) was allowed. MAIN OUTCOME MEASURES: Clinical demographic variables, peripheral blood counts, serum chemistries, CD4 lymphocyte count, histopathological subtype of Hodgkin's disease were identified for all patients, who were staged according to Ann Arbor criteria. DATA ANALYSIS: Common Toxicity Criteria were utilized to assess safety; response was assessed using ECOG criteria; and survival was analyzed by Kaplan-Meier methods and difference of survival between pre-HAART and HARART era was compared using log-rank test. RESULTS: Eleven patients (six in pre-HAART era), all but one male, with a median age of 36 years, excellent performance status and advanced International Prognostic Score were treated. Myelosuppression was the major side effect and there were minimal other grade 3 or greater toxicity all of which were promptly reversible. An overall objective response rate of 82% (with 18% complete responses) and median survival duration of 24 months (range 2.5 +/- 68) were observed. Survival was markedly improved in patients treated in the HAART era (median not reached versus 7.25 months, p = 0.034). CONCLUSIONS: This feasibility study demonstrates acceptable tolerance and excellent clinical activity of oral combination chemotherapy in patients with AIDS-associated Hodgkin's disease. Improved survival is observed in combination with HAART therapy. Dose-modification of this regimen would be suitable to evaluate in the resource constrained setting and larger confirmatory studies are encouraged.

Combination chemotherapy for advanced Hodgkin's disease after failure of MOPP: ABVD and B-CAVe.

Between 1973 and 1982, 110 patients with advanced Hodgkin's disease who had had disease progression while receiving MOPP (mechlorethamine, vincristine, procarbazine, and prednisone) chemotherapy or a relapse after a MOPP-induced complete remission were treated with either ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) (58 patients) or B-CAVe (bleomycin, lomustine, doxorubicin, and vinblastine) (52 patients) chemotherapy in concurrent nonrandomized trials. Responses were seen in 39 of 55 (71%) evaluable ABVD-treated patients--21 (38%) complete and 18 partial responses--and in 34 of 48 (71%) evaluable B-CAVe-treated patients--21 (44%) complete and 13 partial responses. The median duration of the ABVD-induced complete remissions is greater than 25 months compared with 24.3 months for B-CAVe-induced remissions. The 5-year actuarial freedom from progression is 8.5% for evaluable ABVD-treated patients and 25% for B-CAVe-treated patients (p = 0.10). Toxicity in the two treatment groups was similar, with only significant thrombocytopenia (platelet count, less than 50 000/mm3) being more common with B-CAVe. Although most patients with Hodgkin's disease refractory to MOPP treatment will respond to either ABVD or B-CAVe chemotherapy, subsequent long-term disease-free survival is unusual. The need for improved treatment programs for this patient group is evident.
