RESUMO

PURPOSE: To compare standard and intensive treatment strategies for patients with high-grade non-Hodgkin's lymphoma (NHL) of poor prognosis, defined by the international prognostic index. PATIENTS AND METHODS: Thirty-four patients received standard chemotherapy with 11 weeks of doxorubicin, cyclophosphamide, vincristine, bleomycin, etoposide, prednisolone, and methotrexate (VAPEC-B), and 33 received intensive treatment with 7 weeks of VAPEC-B, three cycles of ifosfamide/cytarabine, then high-dose busulfan/cyclophosphamide followed by autologous blood progenitor-cell (BPC) transplantation. RESULTS: Twelve of 33 patients in the intensive group and 26 of 34 patients in the standard group have died. The median follow-up time for the surviving patients is 31 months and 68 months, respectively. At 2 years, the actuarial estimates of event-free survival (EFS) were 61% versus 35% (P = .01) and of overall survival, 64% versus 35% (P = .01). A significant reduction in the event rate (progression or death) was maintained after adjustment for age and the number of risk factors. The estimated risk of experiencing an event was 0.37 (95% confidence interval [CI], 0.16 to 0.84) in the intensive group compared with the standard group. CONCLUSION: Patients with poor prognostic features who received high-dose therapy and BPC rescue had a superior EFS. The survival differences observed in this study justify a formal comparison in a randomized study.

RESUMO

A multicenter phase II study of INTRON, recombinant alpha-2 interferon (Schering Corp, Kenilworth, NJ), in patients with relapsing or refractory myeloma was initiated. Patients received either intravenous therapy for two weeks followed by subcutaneous therapy or subcutaneous dosing from initiation of treatment. Of 38 evaluable patients, 19 were refractory and 19 had relapsed at entry. Twenty-five of 38 had received prior treatment with multiple drugs. Responses were seen among 2/19 refractory patients and 5/19 relapsing patients. Three of seven responders continue to respond for more than one year while receiving maintenance therapy. Most patients experienced improvement in bone pain, and one patient, with a complete response, had healing of bone lesions. Survival curves show a statistically significant improvement in survival for responders v nonresponders. INTRON was well-tolerated with only four patients discontinuing treatment due to adverse effects. Thirty-two percent of patients had hematologic toxicity requiring dose adjustment; however, there was no evidence of cumulative hematologic toxicity. No patients developed serum neutralizing factors to interferon. Additional trials are warranted to study the activity of INTRON in previously untreated patients.

RESUMO

This paper reports the five-year follow-up (range, 1-8 years) of 56 patients with pathologic stage IIIA Hodgkin's disease randomized for chemotherapy alone or chemotherapy followed by radiotherapy to previous areas of disease (26 treated with mustine, vinblastine, procarbazine, and prednisolone [MVPP] alone, 30 with MVPP and radiotherapy). Of the 56 patients 53 (95%) achieved a complete remission with chemotherapy and of these only five (9%) have relapsed; three died of Hodgkin's disease. There was no improvement in relapse-free survival associated with the uses of radiotherapy following chemotherapy but in view of the small numbers of relapses and the excellent results following chemotherapy alone, a significant improvement could not be expected. The use of MVPP alone can be recommended as an alternative therapy for patients with stage IIIA Hodgkin's disease. This avoids both the physical and psychologic morbidity associated with the high relapse rate following extensive primary radiotherapy and the necessity of combined modality treatment for about half these patients. The question of whether radiotherapy should be given to areas of previous bulk following chemotherapy has not yet been answered in this trial which is continuing.

RESUMO

PURPOSE: We report the results of a prospectively randomized study that compared the combination of epirubicin, cisplatin, and protracted venous infusion fluorouracil (5-FU) (ECF regimen) with the standard combination of 5-FU, doxorubicin, and methotrexate (FAMTX) in previously untreated patients with advanced esophagogastric cancer. PATIENTS AND METHODS: Two hundred seventy-four patients with adenocarcinoma or undifferentiated carcinoma were randomized and analyzed for survival, tumor response, toxicity, and quality of life (QL). RESULTS: The overall response rate was 45% (95% confidence interval [CI], 36% to 54%) with ECF and 21% (95% CI, 13% to 29%) with FAMTX (P = .0002). Toxicity was tolerable and there were only three toxic deaths. The FAMTX regimen caused more hematologic toxicity and serious infections, but ECF caused more emesis and alopecia. The median survival duration was 8.9 months with ECF and 5.7 months with FAMTX (P = .0009); at 1 year, 36% (95% CI, 27% to 45%) of ECF and 21% (95% CI, 14% to 29%) of FAMTX patients were alive. The median failure-free survival duration was 7.4 months with ECF and 3.4 months with FAMTX (P = .00006). The global QL scores were better for ECF at 24 weeks, but the remaining QL data showed no differences between either arm of the study. Hospital-based cost analysis on a subset of patients was similar for each arm and translated into an increment cost of $975 per life-year gained. CONCLUSION: The ECF regimen results in a survival and response advantage, tolerable toxicity, better QL and cost-effectiveness compared with FAMTX chemotherapy. This regimen should now be considered the standard treatment for advanced esophagogastric cancer.

RESUMO

In a prospective study of 32 patients with solitary myeloma of bone treated between 1974 and 1984, the median survival was 117 months. Twenty of the patients developed multiple myeloma with a median time to dissemination of 46 months. A multivariate analysis of presenting prognostic factors identified osteopenia (P less than 0.000003) and immunoparesis (P less than 0.00002) as the only independent prognosticators of overall survival. The removal of patients with osteopenia or immunoparesis at presentation identified a group of patients with 80-90% chance of surviving 10 years. Patients with either of the risk factors have a median survival of 27 months similar to patients with multiple myeloma, and should be considered for early systemic treatment.

RESUMO

We examined the tolerability and safety of interleukin-6 (rhIL-6) when administered prior to and concurrent with vincristine, doxorubicin and dexamethasone (VAD) in patients with progressive multiple myeloma previously treated with VAD alone. Typical rhIL-6-related effects such as fever, chills, acute phase reactions and reversible abnormalities in liver function tests were observed. The study examined whether rhIL-6 predictably modulated indices of myeloma activity. No consistent, predictable change in myeloma-related parameters was documented upon rhIL-6 administration for either 8 days or 11 days prior to and concurrent with VAD. Two patients showed improved sensitivity to VAD chemotherapy when this was administered with rhIL-6. The overall response rate to rhIL-6 and VAD therapy in this study of relapsed and refractory patients was 50%, comparable to our previous experience with VAD alone in this cohort of patients.

RESUMO

65 patients with metastatic gastric carcinoma were treated with a combination of methotrexate 1.5 g/m2 with 5-fluorouracil 1.5 g/m2 on day 1 and doxorubicin 30 mg/m2 with mitomycin 4 mg/m2 on day 14. Cycles of chemotherapy were repeated every 4 weeks. The overall response rate was 29% with 6% complete responses and 23% partial responses. Prognostic factors that individually affected response were Karnofsky performance (P less than 0.002), and site of the primary tumour (P less than 0.007). Multivariate analysis showed that only increasing Karnofsky performance (P = 0.01) and disease status (P less than 0.02) (patients with recurrent tumours responding better than patients with postoperative residual disease and those with inoperable disease) were important in predicting response to therapy. The overall median survival was 7 months. All 4 patients with a complete response are alive in remission at 13, 28, 48 and 52 months from the date of starting chemotherapy. Univariate analysis identified increasing Karnofsky performance (P less than 0.0001), response to chemotherapy (P less than 0.02) and higher serum albumin (P less than 0.03) as prognostic indicators for survival. Multivariate analysis, of pretreatment factors and day 14 full blood count showed that only Karnofsky performance (P less than 0.0001) and day 14 platelet count (P less than 0.03) were shown to predict survival, higher platelet values being associated with decreased survival.

RESUMO

Thirty-three episodes of septicaemia caused by viridans streptococci are reported in 32 adults under treatment for malignant diseases. The underlying diseases were acute leukaemia (17), lymphoma (4), myeloma (1), small cell carcinoma of the bronchus (6), carcinoma of the breast (2) and carcinoma of the stomach (2). Important predisposing factors included severe neutropenia and oral mucositis due to intensive chemotherapeutic regimens. There was a poor response to standard empirical antibiotics and a mortality of 12%. A role for prophylactic penicillin in high risk groups is suggested.

RESUMO

To assess any synergistic stimulatory effect in vivo of Interleukin 3 (IL-3) and Granulocyte Macrophage-Colony Stimulating Factor (GM-CSF) upon white cell and platelet counts, toxicity and antitumour effect, we conducted this phase I study. IL-3 0.25, 0.5 or 5 micrograms/kg/day for 1, 4 or 7 days was given by continuous intravenous (i.v.) infusion to 35 patients with advanced malignancy. 21 of the 35 patients also received sequential or overlapping treatment with continuous i.v. infusion of GM-CSF 1 or 3 micrograms/kg/day for up to 10 days. Monotherapy with IL-3 producted significant dose related increases in platelets and white cell counts. Combinations of IL-3 and GM-CSF also produced increases in white cell counts, but these were no greater than would be expected following GM-CSF treatment alone. There was a trend for platelets to increase more in patients receiving IL-3 and GM-CSF than those receiving IL-3 alone, but this did not reach statistical significance. In general, IL-3 and combinations of IL-3 and GM-CSF were well tolerated and the most common side-effect was fever. A maximum tolerated dose was not reached and antitumour effects were not seen. Future studies using combinations of IL-3 5 micrograms/kg/day and GM-CSF 3 micrograms/kg/day may help to define the optimal therapeutic regimen.

RESUMO

The aim of the study was to determine treatment outcome and identify a particularly high risk group in a consecutive series of 66 patients with poor prognosis high grade lymphoma (NHL) treated with conventional induction chemotherapy followed by high-dose chemotherapy (HDCT) and peripheral blood stem cells (PBSC) rescue. Fifty-one patients with intermediate grade NHL (Kiel) and two or three adverse prognostic features as defined by the age-adjusted International Prognostic Index (IPI) received induction treatment with 7 weeks of doxorubicin, cyclophosphamide, vincristine, bleomycin, etoposide, prednisolone and methotrexate (VAPEC-B) followed by three cycles of ifosfamide/cytarabine. Fifteen patients with high grade Burkitt's and lymphoblastic NHL received 11 weeks of VAPEC-B followed by three cycles of high-dose methotrexate. HDCT for all 66 patients consisted of busulphan/cyclophosphamide followed by autologous PBSC rescue. Thirty-one patients (47%) received HDCT in first complete remission (CR/CRu) and 34 patients (52%) in first partial remission (PR) after conventional chemotherapy. Following HDCT, 42 patients (64%) were in CR/CRu, 19 patients (29%) in PR and one patient had progressive disease. There were four toxic deaths. After a median follow-up period of 27 months (range 7-73) in 46 surviving patients, the actuarial 3-year estimates of overall survival, event-free survival (EFS) and freedom from progression (FFP) were 67%, 65% and 70%, respectively. In univariate analysis, prognostic factors associated with reduced EFS were mediastinal bulk (P = 0.02), > or = 3 extra-nodal sites (P = 0.02), remission status prior to HDCT (P = 0.05), low albumin (P = 0.08) and raised ESR (P = 0.09). No significant difference was observed between patients with intermediate or high grade NHL or between patients with two or three adverse IPI features. Multivariate analysis identified mediastinal bulk (P = 0.01), > or = 3 extra-nodal sites (P = 0.01) and low albumin (P = 0.03) as joint predictors of poor EFS. Remission status prior to HDCT was not found to be significantly associated with reduced EFS, FFP or survival, suggesting early introduction of HDCT may benefit patients with a PR. Based on these three adverse features, three groups (0, 1 or > or = 2 features) could be identified with differing EFS, survival and freedom from progression (FFP) rates at 3 years; 85%, 63% and 20%, respectively for EFS, 84%, 64% and 25% for survival and 85%, 66% and 33%, respectively for FFP. This prognostic model may identify patients with a particularly poor prognosis despite HDCT, who may benefit from other therapeutic approaches.

RESUMO

Liposomal amphotericin (AmBisome) 2 mg/kg three times weekly was compared with placebo as prophylaxis against fungal infection in patients undergoing chemotherapy or bone marrow transplantation (BMT) for haematological malignancies. Prophylaxis began on day 1 of chemotherapy and continued until neutrophils regenerated or infection was suspected. Of 161 evaluable patients, 74 received AmBisome and 87 received placebo. Proven fungal infections developed in no patients on AmBisome and in three on placebo (3.4%) (P = NS). Suspected fungal infections requiring intervention with systemic antifungal therapy (usually amphotericin B) occurred in 31 patients on AmBisome (42%) and in 40 on placebo (46%) (P = NS). Suspected deep-seated infections developed in 21 (28.3%) and 31 (35.6%) patients, respectively (P = NS). Time to develop a suspected or proven deep-seated infection showed a trend in favour of AmBisome (P = 0.11). Fifty patients had fungal colonisation (48 with Candida spp, two with Aspergillus spp) of at least one body site during prophylaxis; 15 patients while receiving AmBisome (20%) and 35 while on placebo (40%) (P < 0.01). Time to colonisation was significantly delayed in the group receiving AmBisome (P < 0.05). Treatment-related toxicity was modest and no additional toxicity was observed in patients receiving AmBisome. AmBisome 2 mg/kg three times weekly is safe and reduces fungal colonisation in patients receiving intensive chemotherapy or BMT. However, despite encouraging trends, prophylactic AmBisome did not lead to a significant reduction in fungal infection or in requirement for systemic antifungal therapy.

RESUMO

Eleven patients with acute myeloid leukaemia have been transplanted with autologous marrow grown in long-term bone marrow culture. In the high risk group (six patients who had all previously relapsed) the procedure induced a remission in two patients who were in florid relapse at the time of the transplant. Five patients were transplanted in first remission and they remain well and disease-free between 150 and 12 weeks after their autologous transplant.

RESUMO

Incubation of CML marrow in long-term culture (LTC) conditions may result in selection of normal (Ph-) LTC-initiating cells (LTC-IC) as early as 10 days, and in production of Ph- clonogenic cells and mature end cells within 5 weeks. This was the rationale for using marrow cells from 10-day-old LTC to autograft nine chronic phase CML patients, ineligible for HLA-matched sibling donor transplant, and who were selected on the basis of a pre-transplant screening LTC test. Of the transplanted patients three died; two of graft failure and one of therapy-related toxicity with 97% Ph- cells 16 months following the autograft. The reconstituting haemopoietic cells in the seven engrafted patients were 100% Ph- in four, > or = 90% Ph- in two and 71% Ph- in the seventh, with a duration of complete cytogenetic response of 6-12 months. Three patients reverted to chronic phase and 100% Ph+ haemopoiesis 27-36 months post-autograft. The other three patients remain in continuous haematological remission with 22% Ph- cells in one and complete cytogenetic remission in the other two 3-4 years post-autograft. IFN therapy was generally introduced on the first evidence of recurrence of Ph+ cells or of cytogenetic deterioration. Further strategies to modulate immune surveillance in vivo may improve the outcome of cultured marrow autografts which give an initial and rather prolonged bias towards Ph- haemopoiesis.

RESUMO

Two cases in which macroglobulinaemia was associated with intestinal lymphangiectasia are recorded. Immunoperoxidase stains demonstrated a high content of monoclonal IgM in the intestinal lymph. The seven previously recorded examples of this association are reviewed. It is concluded that the concurrence of these two conditions is not merely fortuitous, and that increased viscosity of the lymph consequent on its high IgM content may be important in the pathogenesis of the intestinal lymphangiectasia.

RESUMO

AIM: To evaluate a newly developed aspergillus mitochondrial gene PCR-ELISA assay for the early diagnosis of invasive pulmonary aspergillosis (IPA) in neutropenic patients. METHODS: The aspergillus mitochondrial gene was chosen for the amplification target for use with a solution hybridisation assay with colorimetric end stage detection in microtitre plate format (PCR-ELISA). The study group comprised neutropenic patients undergoing febrile episodes not responding to standard antibacterial antibiotics. Patients underwent computed tomography and bronchoscopy. Bronchoalveolar lavage (BAL) fluids were examined by culture and PCR. RESULTS: The aspergillus mitochondrial gene PCR-ELISA was both sensitive (100%) and specific (100%) for IPA in neutropenic patients. All 12 patients with definite or probable IPA had PCR positive BAL fluids. None of the patients with undiagnosed or confirmed infections of other aetiologies were mitochondrial PCR positive. Speciation based upon amplicon size difference was possible. CONCLUSIONS: Aspergillus mitochondrial DNA PCR-ELISA on BAL fluid is useful in the early diagnosis of IPA in neutropenic patients alone or, potentially, as an indication for thoracic computed tomography.

RESUMO

This study was designed to evaluate the clinical tolerance to multiple IM injections of rDNA-produced human alpha-2 interferon (IFN) (Schering-Plough 30500) in patients with solid tumours. IFN was administered in escalating IM doses in separate groups of patients daily for 14 days and then twice weekly for a further 10 weeks. The dosage levels were 1, 3, 10, and 30 million U/injection. Subjective toxicity could be divided into two types, acute and chronic. The acute reactions took the form of an influenza-like syndrome consisting in chills, rigors, headache, tremor, nausea, vomiting, and myalgia. These symptoms were dose-related but tachyphylaxis developed with continued dosing. The chronic toxicity consisted of malaise, lethargy, fatigue, anorexia, and confusion. These symptoms were not so dose-dependent and tended to become more severe with prolonged treatment. Objective toxicity consisted of myelosuppression and liver dysfunction. Granulocyte counts below 1.0 X 10(9)/l were seen in three patients at the 30-million-U level, with platelet counts less than 100 X 10(9)/l in two of these. Elevation of the liver enzymes were seen in all five patients treated at 30 million U, but returned to normal after 1 week without IFN in all but one patient. A tolerable dose (IM) for phase II/III studies lies between 3 and 10 million U for daily scheduling and between 10 and 30 million U for twice-weekly injections.

RESUMO

This paper reports the 8-year results of comparing the use of two types of adjuvant chemotherapy following involved field radiotherapy for clinical stages I and II high-grade non-Hodgkin's lymphoma. Twenty-four patients received 6 weeks of VAP plus 2 years of oral maintenance chemotherapy, and 30 had six cycles of CMOPP. Four patients were not in complete remission at completion of i.v. chemotherapy (CR rate 91%). Ten patients (18.5%) have relapsed (VAP/M = 5; CMOPP = 5), with only two of these remaining alive, both of them being disease free. There have been three deaths from intercurrent causes, one from malignant melanoma and the other two from myocardial infarction. The relapse-free survivals at 2, 5 and 8 years were 80%, 76% & 76% respectively. The overall survivals at the same time points were 86%, 72% & 68%. There were no significant differences in either relapse-free or overall survival for either of the two treatment groups. The shorter period of weekly intravenous chemotherapy (VAP/M) was better tolerated than 36 weeks of CMOPP, and the former appears to produce equivalent results.

RESUMO

We have analysed the rearranged Ig heavy chain (IgH) genes in a series of 28 cases of multiple myeloma (MM), in order to extend the study of Ig heavy chain variable (VH) gene usage in B lymphoid malignancies and to explore the ontogenic compartment from which transformed precursor cells arise in this disease. We were able to amplify 28 rearranged alleles by polymerase chain reaction from 23 of these cases, using a common joining region (JH) amplimer together with a panel of VH family-specific amplimers. The pattern of VH family usage was similar to that reported in normal peripheral blood B cells with infrequent usage of VH5 and VH6 genes. However, nucleotide sequence analysis of 17 IgH alleles revealed rearrangement of other VH family members, closely related to known developmentally regulated VH genes, some of which are known to be associated with autoimmune specificities. In contrast to previous findings on more immature B lineage malignancies, the rearranged genes diverged extensively from consensus germline sequences, consistent with somatic mutation. These findings support the hypothesis that the major proliferating precursor in MM arises at, or following a stage of T cell-dependent germinal centre proliferation in lymphoid follicles.

RESUMO

Seventeen patients with small cell lung cancer were entered into a dose ranging phase I-II study using rhGM-CSF (Glaxo). In the phase I study patients received 50, 150, 300 or 500 micrograms/m2 GM-CSF for 10 days by daily subcutaneous injection. Full blood counts were performed thrice weekly. After 4 days off all therapy patients then received chemotherapy with doxorubicin 50 mg/m2 i.v. bolus, day 1, ifosfamide 5 g/m2 with mesna 5 g/m2 over 24 h by continuous infusion followed by mesna 3 g/m2, and etoposide 120 mg/m2 i.v. on days 1-3. A total of six courses of chemotherapy were given. In the phase II study patients received the same dose of GM-CSF as in the phase I. GM-CSF was given 24 h after the last dose of chemotherapy for 14 days. Full blood counts were checked thrice weekly and the incidence of infections noted. Patients were randomised to receive GM-CSF with either odd or even courses of chemotherapy. The leucocyte count rose from a mean of 8.7 to 21.6 x 10(9)/l at the 50 micrograms/m2 GM-CSF dosage and from 11.4 to 39.4 x 10(9)/l at the 500 micrograms/m2 dosage during the phase I study. Phase I toxicity was: bone pain in 65% of patients, rash in 47%, fever in 24%, lethargy in 12% and diarrhoea in 12%. In the phase II study the duration of neutropenia was less during the chemotherapy courses with GM-CSF (p = 0.04) but the number of infections was similar.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMO

The clinical and molecular epidemiology of two clusters of colonization and infection of patients by glycopeptide-resistant enterococci (GRE) on a leukaemia and bone marrow transplantation unit was studied over a two-and-a half-year period. Thirty-five patients became colonized, of whom six developed clinical infections. Of the 53 isolates of GRE, 49 were Enterococcus faecium, multiply-resistant to vancomycin and ampicillin. DNA fingerprinting of 48 E. faecium isolates by pulsed-field gel electrophoresis identified six DNA types. One strain of VanB phenotype E. faecium predominated during the initial outbreak, and an unrelated strain of the VanA phenotype was present in a second cluster. Environmental and patient isolates of E. faecium were indistinguishable by DNA typing. The VanA phenotype enterococci probably arose by transfer from the renal ward at a nearby hospital, and a patient with persistent diarrhoea may have contributed to contamination and cross-infection. GRE may cause significant infections in immunocompromised patients, and are readily transmitted between them. GRE were controlled, but not eradicated on the unit; infection control measures included improved environmental cleaning and modification of antibiotic use. In order to control GRE, it is necessary to educate healthcare workers and implement the traditional, effective values of good personal hygiene and environmental cleanliness.
