High-dose chemotherapy with autologous peripheral blood stem cell transfusion in the treatment of advanced testis cancer

Four patients with advanced testis cancer were treated by high-dose chemotherapy supporting by autologous peripheral blood stem cell transplantation. High-dose chemotherapy (carboplatin 250 mg/m2 or nedaplatin 200 mg/m2, etoposide 1,500 mg/m2, ifosphamide 7.5 g/m2 was given and peripheral blood stem cell transfusion was performed 72 hours after the last dose of chemotherapy. High-dose chemotherapy. was given followed by 1 or 2 cycles of pre high-dose therapy consisting of cisplatin 100 mg/m2 or carboplatin 500 mg/m2, etoposide 450 mg/m2, ifosphamide 6 g/m2. All 4 patients were evaluable. Three patients obtained a complete response and one showed a partial response. The partial responder was given RPLND. The RPLND specimen showed necrotic tissue.     

Cycles of dose-intensive chemotherapy with peripheral stem cell support in persistent or recurrent platinum-sensitive ovarian cancer

OBJECTIVE: The objective was to determine the toxicity and surgically documented response rate of sequential high-dose chemotherapy with peripheral stem cell support in patients with persistent or recurrent cisplatin-sensitive ovarian cancer. METHODS: Fourteen patients (average age, 45 years) were treated with cyclophosphamide (4.5 g/m2), followed by granulocyte colony-stimulating factor (G-CSF)-stimulated peripheral stem cell harvests. The subsequent regimen prescribed three courses of carboplatin (1 g/m2) and cyclophosphamide (1.5 g/m2 with 2-mercaptoethanesulfonate) every 2 weeks with stem cell support. This was followed by three courses of paclitaxel at 250 mg/m2 every 2 weeks with G-CSF support only. Six patients were entered on the basis of a positive second-look laparotomy and 8 patients had a first recurrence after at least a 6-month disease-free interval. RESULTS: Fourteen patients were entered and 12 patients completed all planned courses of therapy (mean time, 13 weeks). Normal hematopoiesis was reestablished after each cycle. Hospitalization for neutropenic fever occurred in 11/93 cycles (11.8%). Thirteen patients required blood transfusions and in 12 patients platelet transfusions were given. One patient had grade 3 neurotoxicity. An initial elevated CA 125 returned to normal in 7/8 patients (88%) and 71% of patients with measurable disease responded to therapy. There were 2 pathologic complete responders (PCR), making the PCR rate 2/14 or 14% (0-35%). CONCLUSION: Although this regimen was well tolerated and clinical response rates were high, the surgically documented response rate was not clearly superior to conventional salvage regimens in platinum-sensitive patients.     

Tandem and triple high-dose chemotherapy with autologous stem cell rescue in metastatic breast cancer

The purpose of this phase II study was to evaluate the therapeutic efficacy and toxicity of a tandem or triple high-dose chemotherapy (HDC) with autologous peripheral blood stem cell transplantation (PBSCT) in patients with metastatic breast cancer (MBC) as first line chemotherapy. Conventional chemotherapy consisted of two cycles of epirubicin 120 mg/m2 and ifosfamide 7500 mg/m2 in the case of tandem HDC and one cycle of paclitaxel 135 mg/m2, epirubicin 90 mg/m2 and ifosfamide 6000 mg/m2 in the case of triple HDC. Tandem HDC was composed of two cycles of epirubicin 180 mg/m2, ifosfamide 12000 mg/m2 and carboplatin 900 mg/m2. In the case of triple HDC, paclitaxel 180 mg/m2, etoposide 1500 mg/m2 and thiotepa 600 mg/m2 was added as the third cycle. Patients with tandem HDC (n = 20) were evaluable for both survival and toxicity, and patients with triple HDC (n = 21) only for toxicity because of short-term follow-up. Both tandem and triple HDC were well tolerated and could be safely administered. Non-hematological WHO grade 3 or 4 toxicities were mucositis (8), temporary renal insufficiency (1), myocardial infarction (1), and neuropathy (1). No toxic death occurred. The Kaplan-Meier estimates for 44-months without progression and the overall survival were 12% and 38% respectively. The median survival was 22 months (95% CI: 7.4-51.7 months) and the median progression-free interval 14 months (95% CI: 5.1-43.7 months). In a population with an unfavorable prognosis, tandem HDC showed similar efficacy as to that described in other phase II studies. Triple HDC seems not to improve patient outcome compared to tandem HDC, but a long-term follow up is required.     

Decentralized high-dose cytostatic treatment with autologous stem cell support]

In the past high-dose chemotherapy with autologous stem cell support in the treatment of certain types of cancer, was centralized to two hospitals in Norway. Almost three years ago it was decided that the treatment should be offered by all five university hospitals. In the northernmost university hospital of Norway, Troms?, peripheral stem cells were harvested from 29 patients after successful mobilization with chemotherapy and granulocyte colony-stimulating factor (G-CSF). After high-dose chemotherapy, more than 2 x 10(6) CD34-positive stem cells/kg were transplanted in 24 patients and a sign of reconstitution of bone marrow function was achieved with mean time for neutrophils > 0.5x10(9)/l, 9.8 days and for platelets > 20x10(9)/l, 10.8 days. No treatment-related deaths have occurred. Transplantation of selected CD34-positive stem cells has been performed in one patient. Recovery was comparable to the recovery of patients who had undergone transplantation with unselected products. This indicates that even small centres performing as few as ten procedures per year may offer high-dose chemotherapy with autologous stem cell support safely and successfully.     

High-dose chemotherapy with autologous stem cell support in poor-risk germ cell tumors

We propose a simple and fast method of detecting apoptosis using an automated hematology analyzer. Detection is based on cellular optical light scatter properties and demonstration of the membrane fragility which characterizes cells undergoing the process of apoptosis. As part of it's routine leucocyte differential analysis, the Abbott Cell-Dyn 4000 collects multi-angle cellular light scatter data. In addition red fluorescence (FL3) emitted by cells following propidium iodide labeling is collected. This provides quantitation of both the erythroblast count and a leukocyte viability index (WVF). Fresh or cryopreserved peripheral blood cells from 17 B-chronic lymphocytic leukemia (B-CLL) patients were incubated in presence of theophylline, fludarabine or in medium alone. After 36-hrs of culture the percentage of apoptotic cells of the sample was determined from the parameters of the CD 4000 described above and thereafter this was compared with reference methods for estimation of apoptosis. The reference methods used were in situ detection of cell death on slides (TUNEL test) and also flow cytometry (Annexin V). Results showed an excellent correlation between the 3 techniques. This rapid, easy and reliable method of quantifying apoptosis may be very useful means of routinely predicting the response to chemotherapy.     

Studies with high-dose chemotherapy and subsequent autologous stem cell transplantation in breast carcinoma

Survival rates for several subgroups of patients with breast cancer treated with conventional therapy remain poor. Only about 30% of patients with primary breast cancer involving more than 9 axillary lymph nodes remain disease-free at 5 years from diagnosis despite surgery, conventional-dose chemotherapy and radiotherapy. Metastatic breast cancer with 5 year survival rates of about 3% generally represents incurable disease. Chemotherapeutic agents are conventionally limited by side effects. The easy procurement of haematopoietic stem cell support through mobilization of peripheral blood progenitors has spurred the development of new strategies employing high-dose treatment for treatment of high risk breast cancer. Autologous stem cell support antagonizes chemotherapy-induced myelotoxicity and thereby allows dose escalation by a factor of 1.5 to about 20. Pilot studies evaluating significant dose escalation in adjuvant treatment of patients with advanced disease have resulted in an apparent improvement in event-free survival rates to over 70%. Repetitive applications of chemotherapy at myeloablative doses are now increasingly being used. Data from prospectively randomized phase III trials will not be available before the end of 1998. For metastatic breast cancer one prospective, randomized clinical trial has been published. Results are significantly better for patients who have been treated by high-dose chemotherapy compared to patients who received conventional polychemotherapy (median survival 90 vs. 45 weeks). For methodological reasons (small patient numbers, patient selection, weak standard therapy etc.) results from the trials cited above are under discussion. Until publication of further results from ongoing phase III trials HDC for breast cancer remains experimental and should not be given outside of clinical trials.     

The toxicity of radiotherapy following high-dose chemotherapy with peripheral blood stem cell support in high-risk breast cancer: a preliminary analysis

High-dose chemotherapy with autologous bone marrow and/or peripheral blood stem cell (PBSC) support is increasingly employed in the adjuvant treatment of high-risk breast cancer. Subsequent radiotherapy has been reported to be associated with morbidity and mortality resulting from pulmonary toxicity. In addition, the course of radiation therapy may be hampered by excess myelosuppression. The aim of this study was to investigate the contribution to radiation-induced toxicity of a high-dose chemotherapy regimen (CTC) that incorporates cyclophosphamide, thiotepa and carboplatin, in patients with high-risk breast cancer. In two randomised single institution studies, 70 consecutive patients received anthracycline-containing adjuvant chemotherapy (FEC: 5-fluorouracil, epirubicin and cyclophosphamide) followed by radiotherapy to achieve maximal local control. Of these patients, 34 received high-dose CTC with autologous PBSC support. All patients tolerated the full radiation dose in the planned time schedule. Radiation pneumonitis was observed in 5 patients (7%), 4 of whom had undergone high-dose chemotherapy (P = 0.38). All 5 responded favourably to prednisone. Fatal toxicities were not observed. Myelosuppression did not require interruption or untimely discontinuation of the radiotherapy, although significant reductions in median nadir platelet counts and haemoglobin levels were observed in patients who had received high-dose chemotherapy (P = 0.0001). The median nadir of WBC counts was mildly but significantly decreased during radiotherapy (P = 0.01). Red blood cell or platelet transfusions were rarely indicated. Adequate radiotherapy for breast cancer can be safely administered after high-dose CTC with autologous PBSC support. Radiation-induced myelotoxicity is clearly enhanced following CTC, but this is of little clinical significance. Radiation pneumonitis after high-dose therapy may occur more often in patients with a history of lung disease or after a relatively high radiation dose to the chest wall. Other high-dose regimens, particularly those incorporating drugs with known pulmonary toxicity (such as BCNU), may predispose patients to radiation pneumonitis.     

Prognosis of hematological patients with relapse following high-dose chemotherapy and autologous stem cell transplantation

A retrospective analysis of the outcome for 283 haematological patients who relapsed after high dose chemotherapy and autologous stem cell transplantation during a five year period from 1989 to 1994 is presented. The patients were treated in accordance with local regimes at 20 Nordic transplantation centers and included patients with acute leukemia (157 patients), multiple myeloma (16 patients) and lymphoma (110 patients). Two hundred and twenty-nine patients with relapse or progressive disease were given chemo- and/or radiotherapy and the response was evaluated after 90 days. Fifty-four patients (24%) obtained a complete remission and 44 patients (19%) partial remission. The overall median survival after relapse was five months. In the group who received salvage treatment the median survival was seven months, and for the 54 patients in complete remission the median survival was 15 months. We found that survival after relapse depends upon primary disease, the time from transplantation to relapse and whether salvage therapy was initiated.     

Much ado about not...enough data: high-dose chemotherapy with autologous stem cell rescue for breast cancer

Among hematologic malignancies, there are three disorders whose behavior is governed principally by the abnormal proliferation of a malignant megakaryocytic clone or a product thereof. These disorders are essential thrombocythemia, agnogenic myeloid metaplasia, and acute megakaryoblastic leukemia. Although there are other myeloproliferative diseases that can have high platelet counts, the major pathobiology of those diseases most commonly results from the proliferation of other hematopoietic lineages. Despite the rarity of the three disorders of malignant megakaryopoiesis mentioned above, advances have been made in the diagnosis, prognosis, and treatment of these disorders in recent years. However, understanding of the cellular and especially molecular pathobiology lags far behind.     

Mobilization of peripheral blood stem cells in advanced ovarian cancer

High-dose chemotherapy with hematopoietic support has been expected to improve the survival of advanced ovarian cancer patients in recent years. An essential component of such treatment has been the ability to collect and reinfuse a large number of peripheral blood stem cells (PBSCs) following high dose therapy. This study was designed to determine which clinical and hematological factors would be better indicators to collect the proper volume of PBSCs. Thirteen patients received a total of 24 courses of induction chemotherapy and 69 of apheresis. We usually mobilized stem cells using CEP chemotherapy (cisplatin 50-70 mg/m2, epirubicin 50 mg/m2 and cyclophosphamide 1.5 g/m2) with G-CSF and CEE regimen (cyclophosphamide 2.0 g/m2, epirubicin 50 mg/m2, and etoposide 50 mg/m2) as a salvage for mobilization. We obtained an average 5 x 10(6)/kg of CD34+ cells for 3 days as one course. The number of CD34+ cells collected significantly depended on the platelets and reticulocytes on the first day of apheresis, but not a nadir of WBCs. It is concluded that apheresis should be started on recovery of WBCs to 5,000-10,000/microliters, of immature granulocytes to > or = 10% and of reticulocytes to > or = 20%. This study confirmed the feasibility of collecting enough PBSCs to use standard chemotherapy of ovarian cancer patients.     

High-dose chemotherapy with autologous peripheral blood stem cell transplantation for metastatic gastric leiomyosarcoma

We report a case of metastatic gastrointestinal leiomyosarcoma treated with high-dose combination chemotherapy and autologous peripheral blood stem cell transplantation. After incomplete surgical resection, enteral, peritoneal and hepatic involvement remained. Postoperatively, standard-dose chemotherapy with etoposide, ifosfamide, cisplatin and epirubicine, and high-dose chemotherapy with the same agents (carboplatin replacing cisplatin) was given. Treatment was well tolerated and the patient remains in complete remission at 36+ months. We conclude that high-dose chemotherapy followed by autologous peripheral blood stem cell transplantation may be of use as treatment for inoperable residual disease after resection of the primary lesion in gastrointestinal and other soft tissue sarcomas.     

Ciprofloxacin-associated acute renal failure in patients undergoing high-dose chemotherapy and autologous stem cell rescue

The broad spectrum of activity of ciprofloxacin makes it an ideal drug for the prophylaxis of bacterial infections in patients undergoing high-dose chemotherapy (HDC) with autologous stem cell rescue. We present two cases of ciprofloxacin-associated acute renal failure (ARF) in patients undergoing HDC. Maintaining a high index of suspicion for this complication will allow a prompt diagnosis, with discontinuation of the drug usually resulting in a reversal of renal failure. Renal biopsy usually reveals changes compatible with interstitial nephritis, but is not always possible in these patients due to severe thrombocytopenia following HDC. A brief course of steroid therapy may be beneficial although the role of glucocorticoids is difficult to ascertain in the absence of data regarding its efficiency in this clinical setting.     

High dose chemotherapy with peripheral blood stem cell transplantation (PBSCT) For advanced testicular cancer]

Social work for the elderly in a demographical ageing society is not justified per se, but has to prove its utility under the altering social conditions of the changing age-structure. In the field of practice, this has led to an increasing need for professional orientation and to searching for profiles of performance with greater attraction. As manifold as the target groups are the spectra of social work for the elderly is also manifold in its content and methods. Nevertheless, we are able to recognize some general orientations and strategies, which are conceptual adaptions from social work in general, cultural work and educational work--combined with fundamental supplies of social gerontological knowledge. In this sense, social work, for the elderly--in its most advanced realms--should be integrated into an ageing-policy concept, which is of relevance for the society as a whole.     

Aerobic exercise in the rehabilitation of cancer patients after high dose chemotherapy and autologous peripheral stem cell transplantation

BACKGROUND: Fatigue and loss of physical performance are frequent problems of cancer patients. In a pilot study, the authors evaluated the feasibility and effects of aerobic training in the rehabilitation of cancer patients after completing high dose chemotherapy. METHODS: Sixteen patients participated in a specially designed rehabilitation program for 6 weeks. The patients entered the program, which consisted of walking on a treadmill, shortly after completing treatment. Sixteen patients who did not train served as controls. Physical performance (maximum speed on the treadmill test), cardiac function, and hemoglobin concentration were compared at the time of discharge from the hospital and 7 weeks later. At the second examination, fatigue and limitations in daily activities due to impaired endurance were assessed during personal interviews. RESULTS: At the time of discharge from the hospital, maximum physical performance (training group: 6.2 +/- 1.1 km/hour; controls: 6.2 +/- 1.3 km/hour) and hemoglobin concentration (training group: 10.1 +/- 1.4 g/dL; controls: 10.1 +/- 1.2 g/dL) were similar for both groups. After 7 weeks, improvement in maximum physical performance (training group: 8.3 +/- 1.6 km/hour; controls 7.5 +/- 1.3 km/hour) and hemoglobin concentration (training group: 13 +/- 1 g/dL controls: 12 +/- 1.4 g/dL) were significantly higher for the training group (P < 0.05). By the second examination, no patient in the training group but 4 controls (25%) reported fatigue and limitations in daily activities due to low physical performance. CONCLUSIONS: Aerobic exercise improves the physical performance of cancer patients recovering from high dose chemotherapy. To reduce fatigue, this group of patients should be counseled to increase physical activity rather than rest after treatment.     

Two cases of adenosquamous cell carcinoma of advanced cervical cancer treated by carboplatin-based chemotherapy with peripheral blood stem cell autotransplant

In two cases with adenosquamous cell carcinoma of advanced cervical cancer, carboplatin-based chemotherapy was given intraarterially from the internal iliac artery as neoadjuvant chemotherapy, and peripheral blood stem cells (PBSCs) were harvested. After the operation, conventional intravenous chemotherapy with PBSC autotransplant was performed. PBSCs were mobilized by neoadjuvant chemotherapy and G-CSF administration. By the apheresis procedures, 0.7-2.6 x 10(6)/kg CD34 positive cells were obtained. They had no severe side effects from intravenous chemotherapy with PBSCT, and they were free of disease 20 months. Neoadjuvant chemotherapy and G-CSF administration may be capable of mobilization of PBSCs, and chemotherapy with PBSCT may be useful in radioresistant advanced adenosquamous carcinoma of the cervical cancer.     

High-dose busulfan, melphalan and thiotepa followed by autologous peripheral blood stem cell (PBSC) rescue in patients with advanced stage III/IV ovarian cancer

The purpose of this study was to evaluate the efficacy of high-dose chemotherapy (HDC) with busulfan, melphalan and thiotepa (BUMELTT) followed by autologous PBSC infusion in treating patients with advanced ovarian cancer. Thirty-one patients, 18 with stage III/IIIc and 13 with stage IV ovarian cancer, were treated with BU (12 mg/kg), MEL (100 mg/m2) and TT (500 mg/m2) and autologous PBSC rescue. Fifteen patients were in clinical complete remission (CR) at treatment; 11 had platinum-sensitive disease. Sixteen patients were not in CR; two had platinum-sensitive disease. The probabilities of overall survival (OS), event-free survival (EFS) and relapse (R) for all patients at 18 months were 0.57, 0.30 and 0.63; for patients in CR, the rates were 0.87, 0.44 and 0.49 and for patients not in CR, 0.38, 0.13 and 0.81. Two patients (6.5%) died of treatment-related causes. Among the 13 patients with platinum-sensitive disease, all are still alive, with seven having relapsed 129-1021 days after PBSC infusion. OS, EFS and R were 1.00, 0.52 and 0.48. Of the 18 patients with platinum-resistant disease, four remain alive (two in remission). Six patients did not respond and eight relapsed from days 104-429. The OS, EFS and R were 0.33, 0.11 and 0.78. We conclude that BUMELTT is well tolerated in patients with advanced ovarian cancer and results are equivalent to other published HDC regimens.     

Philadelphia chromosome-positive secondary acute myeloid leukemia following high-dose chemotherapy with peripheral blood progenitor cell support for relapsed low-grade non-Hodgkin's lymphoma

We report the case of a 47-year-old patient who developed acute myelogenous leukemia (AML) 18 months after receiving high-dose chemotherapy with peripheral blood progenitor cell support (PBPCT) for relapsed low-grade follicular non-Hodgkin's lymphoma (NHL). Cytogenetic analysis of the leukemic cells showed the translocation (9;22)(q34;q11). In three mitoses, an additional Philadelphia chromosome (Ph1) was present. In the literature, Philadelphia chromosome-positive secondary AML has been described only once before in a patient with multiple myeloma.     

Therapy of highly malignant non-Hodgkin lymphoma with high-dose chemotherapy and stem cell transplantation

Patients with intermediate or high-grade non-Hodgkin's lymphoma are rarely cured of their disease after the failure of conventional therapy. High-dose chemotherapy followed by transplantation of either autologous marrow (ABMT) or peripheral stem cells (PBSCT) offers such patients a new possibility of cure. To patients younger than 60 years and without contraindications high-dose chemotherapy should be offered in case of relapse and bad prognosis. The PARMA-study demonstrated, that high-dose chemotherapy with subsequent autologous stem cell transplants is superior to conventional chemotherapy for relapsing patients. However high-dose chemotherapy in first complete or partial remission followed by ABMT and PBSCT as post-remission therapy for adult NHL has yielded only similar results randomized to those achieved with conventional chemotherapy in several prospectively studies. This approach should be limited to patients with bad prognostic factors (high-intermediate or high-risk groups according to the International Prognostic Factor Project). The success of ABMT and PBSCT in treating these diseases mandates exploration of the best high-dose chemotherapy, the use of autologous or allogenic bone marrow resp. peripheral stem cell for haematopoietic reconstitution and technical aspects such as purging of tumor cells, the short- and long-term transplant-related mortality continues to be a major concern.
