ASHAP--an effective salvage therapy for recurrent and refractory malignant lymphomas.

BACKGROUND: This study was performed to examine the efficacy and toxicity of the combination of adriamycin (ADR), methylprednisolone (solumedrol), cytarabine (Ara-C), and cisplatin (CDDP) in patients with recurrent and refractory malignant lymphomas. PATIENTS AND METHODS: Sixty-five patients with Hodgkin's disease (HD) (n=14) or non-Hodgkin's lymphomas (NHL) (n = 51) were enrolled in the study. The ASHAP therapy consisted of ADR (40 mg/m2 by continuous infusion (CI) over 96 h), methylprednisolone (500 mg i.v., days 1-5), Ara-C (2 g/m2 as a 2-h infusion on day 5), and CDDP (100 mg/m2 by CI over 96 h). RESULTS: Twenty-five patients (38%) achieved complete remission (CR) and 20 (31%) were taken into partial remission (PR) for an overall response rate of 69%. Thirty-two patients with CR or PR following ASHAP underwent high-dose therapy (HDT) with subsequent hematopoietic stem cell transplantation. After a median follow-up of 52 months, 13 patients are in continuous CR (CCR), the 3-year event-free survival (EFS) was 30% for responders and 21% for all patients. The median overall survival (OS) was 12 months (range 0-70 months), and the OS rate after 3 years was 32%. Unfavorable prognostic factors for EFS and OS by univariate analysis were an elevated value of the serum lactate dehydrogenase and refractory lymphoma. The most frequently observed side effects following ASHAP were leukocytopenia and thrombocytopenia of World Health Organization (WHO) grades III/IV in approximately 80% of all courses. Non-hematological toxicities such as gastrointestinal side effects, infections, mucositis, renal and neurotoxicity occurred more rarely and reached WHO grades III/IV only occasionally. No treatment-related mortality with ASHAP was observed. CONCLUSIONS: ASHAP is an effective and moderately toxic salvage therapy for patients with recurrent or refractory HD and NHL. The results in patients responding to ASHAP and afterwards undergoing HDT with stem cell support are comparable with other established protocols and indicate an improvement in survival if HDT is carried out as intensification.

Gemcitabine and cisplatin in the treatment of advanced or metastatic pancreatic cancer.

BACKGROUND: This phase II study was initiated to determine the efficacy and safety of gemcitabine plus cisplatin in patients with pancreatic cancer. PATIENTS AND METHODS: Gemcitabine 1000 mg/m2 was given on days 1, 8, and 15 of a 28-day schedule, and cisplatin 50 mg/m2 on days 1 and 15 to chemonaive patients with locally advanced or metastatic pancreatic cancer. RESULTS: Of the 41 patients enrolled (median age 57, and 61% male), median Karnofsky performance status was 80%. Patients received a median of 4.2 cycles (range 1-11). In 35 evaluable patients, one complete response (CR) and three partial responses (PR) were observed, for an overall response rate of 11% (95% confidence interval (95% CI): 3.2% -26.7%). Stable disease (SD) > 3 months occurred in 20 (57%) patients; 6 survived > or = 1 year. Median time to progressive disease was 4.3 months (95% CI: 3.0-5.7 months). For all patients, median survival was 8.2 months (95% CI: 6.1-10.6 months) with a one-year survival rate of 27%. Therapy was well tolerated. Grade 3-4 neutropenia (no grade 3-4 infection), thrombocytopenia (no bleeding), nausea/vomiting, and alopecia were reported in 29%, 13%, and 2.6% of patients, respectively. CONCLUSIONS: The combination of gemcitabine and cisplatin is a moderately active treatment for patients with locally advanced and metastatic pancreatic cancer without compromising tolerability.

The use of dose-intensified chemotherapy in the treatment of metastatic nonseminomatous testicular germ cell tumors. German Testicular Cancer Study Group.

With the use of a cisplatin-based chemotherapy, metastatic testicular cancer has become a model for a highly curable malignant disease. Current data show that 70% to 80% of patients with this disease will achieve long-term survival following cisplatin/etoposide/bleomycin therapy. The role of high-dose chemotherapy with autologous stem cell support is being investigated in metastatic germ cell cancer in attempts to improve outcome for patients whose disease relapses after standard-dose chemotherapy and for those who present initially with advanced metastatic disease. Prognostic categories for patients receiving high-dose salvage chemotherapy have recently been developed: cisplatin-refractory disease, beta-human chorionic gonadotropin values greater than 1,000 U/L, and primary mediastinal germ cell tumors are factors characterizing patients who will derive less benefit from high-dose chemotherapy than those with chemosensitive disease at relapse. While standard-dose salvage chemotherapy achieves only a 20% long-term survival rate, high-dose salvage chemotherapy may yield a cure rate of approximately 40%. A randomized study comparing high-dose therapy with conventional-dose therapy (IT94 coordinated by the European Group for Blood and Marrow Transplantation) in patients with relapsed disease is ongoing to substantiate this observation. The use of dose-intensive therapy as first-line treatment is currently being studied by several institutions. High-dose therapy may be better tolerated when used first line compared with its use in the salvage situation, and may also achieve a rapid initial cell kill before cytostatic drug resistance develops. The German Testicular Cancer Study Group has developed a sequential high-dose combination regimen of cisplatin/etoposide/ifosfamide given with granulocyte colony-stimulating factor and peripheral blood stem cell support for four cycles every 3 weeks. This ongoing study, started in 1990, had accrued 218 patients with advanced testicular germ cell tumors as of June 1997. Of 141 evaluable patients receiving dose levels 1 through 5, 82 (58%) have achieved complete remission with no evidence of disease and 32 (23%) have achieved partial remission with marker normalization. The early death rate was 8%. Overall and event-free survival rates at 2 years are 78% and 73%, respectively, with a projected 5-year overall survival rate of 74%. Despite favorable preliminary results, this approach cannot be considered standard treatment. Currently, high-dose chemotherapy with peripheral blood stem cell transplantation should be administered to patients with testicular cancer only within controlled clinical trials to allow long-term cure rates and treatment-related late side effects to be evaluated.

Detection of melanoma cells in peripheral blood stem cell harvests of patients with progressive metastatic malignant melanoma.

The detection of melanocyte-specific messenger RNA in patients with malignant melanoma suggests the potential contamination of peripheral blood stem cell (PBSC) harvests by neoplastic cells. In this study, the melanocyte-specific transcripts of tyrosinase and Melan-A/MART-1 were used to detect neoplastic cells in PBSC harvests of nine metastatic malignant melanoma patients. Only one patient's PBSC harvest tested positive for tyrosinase. All harvests were negative for Melan-A/MART-1. Our results suggest that contamination of PBSC harvests with neoplastic cells may not contribute to disease progression following high-dose chemotherapy in advanced malignant melanoma.

High dose chemotherapy with busulfan, cyclophosphamide, and etoposide as conditioning regimen for allogeneic bone marrow transplantation for patients with acute myeloid leukemia in first complete remission.

We explored the combination of busulfan/cyclophosphamide/etoposide as conditioning regimen prior to bone marrow transplantation in 31 patients with acute myeloid leukemia (AML) in first complete remission. The preparative regimen consisted of 16 mg/kg busulfan, 30-60 mg/kg VP-16, and 120 mg/kg cyclophosphamide. With a median follow-up of 30.5 months (range, 5-60 months), 25 patients are alive in continuous complete remission. Estimated disease-free survival at 5 years is 80.5%. Death was due to transplant-related toxicity (graft-versus-host disease and cytomegalovirus infection, graft-versus-host disease and pneumonia, sepsis and mucositis, respectively). None of the patients have relapsed. As demonstrated by the results of this analysis, the conditioning regimen busulfan/cyclophosphamide/etoposide is effective and well tolerated in patients with AML in first complete remission. Main nonhematological toxicities were mucositis and hepatotoxicity. The low mortality and relapse rate appears to justify allogeneic bone marrow transplantation for patients with AML in first complete remission who have an HLA-identical donor. Whether this regimen offers a substantial improvement in disease-free and overall survival over presently used regimens warrants further investigation.

[Patient questionnaire for an epidemiologic cancer registry--results of an initial trial].

For the first time a patient questionnaire was employed for an epidemiologic cancer registry to complete special history data routinely. After a successful pretest in 1995 it is being employed in the region Weser-Ems (Lower Saxony) since March 1996. The quality criterion completeness increased compared to the previously used sheet for history data, which had be filled in by the doctor. The quota of missing questionnaires is 10% and may be lowered by efficient measures. The occupational data should be used critically for comparison with other data sources (e.g. Bundesanstalt für Arbeit [BfA]) or studies, because the code used by the BfA has been designed for other purposes and cannot be applied to investigations of occupational cancer risks. The geographical relation to cancer will be difficult to estimate because of the obvious mobility of the people.

[Interdisciplinary guidelines: cholelithiasis].

Quality management in internal medicine and surgery is especially difficult because of the magnitude of these two subjects. Between the years 1994 and 1996, the German scientific societies of internal medicine developed the manual "Rationelle Diagnostik und Therapie in der Inneren Medizin". The cooperation of colleagues was most helpful when the interests of several internal branches were involved. An even greater challenge is the development of interdisciplinary internal and surgical guidelines, which are presented here for cholelithiasis.

[Evaluation of anamnestic data of cancer patients (comprehensiveness of the "Oldenburg Anamnesis Questionnaire")].

An evaluation of case history data of cancer patients is presented. These data were recorded by means of a case history form in the cancer registry of Weser-Ems between 1988 and 1993 in the Weser-Ems region (Lower Saxony). Completeness and rate of errors were the quality criteria. The completeness was insufficient (23-92%), whereas the rate of errors was low (1%). In the course of years the completeness of the clinically relevant items increased, probably because the form had to be completed by the physician. About 99% of the cancer patients were of German nationality. The cause of registration was mainly the appearance of symptoms or a pathological finding while investigating for another reason. In respect of correlations between anamnestic data and carcinomas smoking or/and alcohol-abusus were significant. There was an association in men between these factors and carcinomas of the oropharynx and oesophagus, respectively of the lung; 85 resp. 75% of the men with theses carcinomas had smoked excersively and/or had abused alcohol. Data concerning the profession of the patients were irrelevant. Gynaecological ananestic data did not yield any new knowledge, which is why these and other items may be ignored. This resulted in a new anamnestic and patient questionnaire sheet were drawn up. These are now being tested in the Weser-Ems region since October 1995.

Epirubicin and ifosfamide in metastatic breast cancer.

In a randomized, phase II trial, we evaluated the effectiveness of continued chemotherapy with epirubicin/ ifosfamide versus unmaintained treatment interruption in advanced metastatic breast cancer. Three hundred fifty-seven patients were enrolled and 331 were evaluable for response. Complete response was achieved in 25 patients (8%) and partial response in 121 patients (37%). Pretreatment status correlated significantly with response (complete and partial response). While 54% of unpretreated patients responded, only 42% of the patients responded who had been pretreated with adjuvant chemotherapy and 33% who had been pretreated in the metastatic stage of disease; 69 patients (21%) had disease progression. Of 11 patients pretreated in both the adjuvant and metastatic setting, only two responded. Toxicity of treatment was mild, with leukopenia being the treatment-limiting factor. Thrombocyte levels were not altered significantly by treatment. Thus, there seems to be room for dose escalation using granulocyte colony-stimulating factor. There was no considerable cardiotoxicity, central nervous system toxicity, or cystitis observed. The low rate of cardiotoxicity appeared to be related to dose fractionation of epirubicin. After randomization of patients to treatment interruption versus continuation of chemotherapy, a longer relapse-free survival was observed for patients who continued chemotherapy (mean relapse-free survival, 2+ months); however, this did not translate into prolonged survival. The cumulative scores of toxicity and quality of life parameters showed increasing superiority for treatment interruption. Therefore, a strategy of treatment until maximum response and subsequent treatment interruption seems to be superior to treatment continuation.
