Bone marrow transplantation for children less than 2 years of age with acute myelogenous leukemia or myelodysplastic syndrome

We analyzed results of 40 infants less than 2 years of age who received bone marrow transplants (BMT) between May 1974 and January 1995 for treatment of acute myelogenous leukemia (AML; N = 34) or myelodysplastic syndrome (MDS; N = 6) to determine outcome and survival performance. Among the AML patients, 13 were in first remission, 9 were in untreated first relapse or second remission, and 12 were in refractory relapse. Patients were conditioned with cyclophosphamide in combination with either total body irradiation (TBI; N = 29) or busulfan (N = 11). Source of stem cells included 6 autologous donors, 15 HLA genotypically identical siblings, 14 haploidentical family members, and 5 unrelated donors. Graft-versus-host disease (GVHD) prophylaxis was methotrexate (MTX) for 17, MTX plus cyclosporine (CSP) for 14, or CSP plus prednisone for 3. Incidence of severe (grade 3-4) regimen-related toxicity was 10% and transplant-related mortality was 10%. Acute GVHD (grades II-III) occurred in 39% of allogeneic patients, and chronic GVHD developed in 40%. Relapse, the most significant problem for patients in this study, occurred in 1 MDS patient and 23 AML patients and was the cause of death for 19 patients. The 2-year probabilities of relapse are 46%, 67%, and 92%, respectively, for patients transplanted in first remission, untreated first relapse or second remission, and relapse. One MDS and 8 AML patients received second marrow transplants for treatment of relapse, and 5 of these survive disease-free for more than 1.5 years. All 6 MDS patients and 11 of 34 AML patients survive more than 1.5 years later. The 5-year probabilities of survival and disease-free survival are 54% and 38% for patients transplanted in first remission and 33% and 22% for untreated first relapse or second remission. None of the patients transplanted with refractory relapse survive disease-free. Outcome was significantly associated with phase of disease at transplantation and pretransplant diagnosis of extramedullary disease. Long-term sequelae included growth failure and hormonal deficiencies. Survival performance was a median of 100% (80% to 100%) and neurologic development for all survivors was appropriate for age. This study indicates that infants with AML have similar outcome after BMT compared with older children and that BMT should be performed in first remission whenever possible. In addition, allogeneic BMT provides effective therapy for the majority of infants with MDS.     

A case of chronic B cell lymphocytic leukemia with expression of CD8 antigen on leukemic cells

PURPOSE: To determine the toxicity and prognosis of patients with relapsed and refractory diffuse aggressive non-Hodgkin's lymphoma (NHL) who underwent an autologous bone marrow transplant (ABMT) using augmented preparative regimens, treated in a major cooperative group setting, and to examine prognostic factors for outcome. PATIENTS AND METHODS: Ninety-four patients with either chemosensitive (50 patients) or chemoresistant (44 patients) relapse, including 22 who failed induction chemotherapy, were treated with high-dose cyclophosphamide and etoposide with total-body irradiation (TBI) (67 patients) or an augmented carmustine (BCNU), cyclophosphamide, and etoposide (BCV) preparative regimen (27 patients) and an ABMT at 16 Southwest Oncology Group (SWOG) transplant centers. All relapsing patients were required to undergo a minimum of two courses of salvage therapy to determine chemosensitivity before transplant. Overall (OS) and progression-free survival (PFS) were determined and a Cox regression model was used to assess potential prognostic variables. RESULTS: Of the 94 eligible patients, there were 10 (10.6%) deaths before day 50 posttransplant because of infection (six deaths), hemorrhagic alveolitis (three deaths), or bleeding (one death). The median 3-year PFS and OS for the entire group was 33% and 44%. For those with chemosensitive disease the PFS and OS were 42% and 55%, whereas for those with chemoresistant disease the PFS and OS were 22% and 29%. The PFS and OS for those failing induction chemotherapy were 27% and 32%. The relapse rates within the first 3 years for the chemosensitive relapse, chemoresistant, and induction failure groups were 61%, 40%, and 59%, respectively. For both PFS and OS, only disease status at transplant was a significant factor in the multivariate Cox model. CONCLUSION: These results single institutional pilot trials exploring augmented preparative regimens. Patients undergoing transplantation for resistant disease, particularly those failing induction chemotherapy, appear to have an improved prognosis as compared with reports using standard preparative regimens. Therapies other than manipulation of standard preparative regimens appear to be required to decrease relapses following autotransplantation.     

High-dose therapy and autologous hematopoietic progenitor cell transplantation for recurrent or refractory Hodgkin's disease: analysis of the Stanford University results and prognostic indices

One hundred nineteen patients with relapsed or refractory Hodgkin's disease (HD) received high-dose therapy followed by autologous hematopoietic progenitor cell transplantation. Three preparatory regimens, selected on the basis of prior therapy and pulmonary status, were employed. Twenty-six patients without a history of prior chest or pelvic irradiation were treated with fractionated total body irradiation, etoposide (VP) 60 mg/kg and cyclophosphamide (Cy) 100 mg/kg. Seventy-four patients received BCNU 15 mg/kg with identical doses of VP and Cy. A group of 19 patients with a limited diffusing capacity or history of pneumonitis received a novel high-dose regimen consisting of CCNU 15 mg/kg, VP 60 mg/kg and Cy 100 mg/kg. Twenty-nine patients (24%) had failed induction therapy and 35 (29%) had progressive HD within 1 year of initial chemotherapy. At 4 years actuarial survival was 52%, event-free survival was 48% and freedom from progression (FFP) was 62%. No significant differences were seen in survival data with the three preparatory regimens. Six patients died within 100 days of transplantation and 5 died at a later date of transplant-related complications. Secondary malignancies have developed in 6 patients, including myelodysplasia/leukemia in four patients and solid tumors in two patients. Regression analysis identified systemic symptoms at relapse, disseminated pulmonary or bone marrow disease at relapse and more than minimal disease at the time of transplantation as significant prognostic factors for overall and event-free survival and FFP. Patients with none of these factors enjoyed an 85% FFP at 4 years compared with 41% for patients with one or more unfavorable prognostic factors (P = .0001). Our results confirm the efficacy of high-dose therapy and autografting in recurrent or refractory HD. Although longer follow-up is necessary to address ultimate cure rates and toxicity, our data indicate that a desire to reduce late effects should drive future research efforts in favorable patients whereas new initiatives are needed for those with less favorable prognoses.     

MRI of hyperpolarized 3He gas in human paranasal sinuses

Relapsed or refractory adult acute lymphoblastic leukemia (ALL) carries a grave prognosis. The most promising strategy for curing these patients is through re-induction chemotherapy followed by successful allogeneic transplant. We studied a new high-dose induction regimen in order to improve the outcome for these patients. Eighteen adult patients with relapsed/refractory ALL were treated on a phase I study of high-dose cytarabine combined with a single escalating dose of idarubicin. Five patients had primary refractory disease and 13 were treated in refractory relapse. Nine patients (50%) had Ph+ ALL. The induction regimen was cytarabine 3 g/m2/day intravenously days 1-5 and idarubicin as a single intravenous dose on day 3. G-CSF 5 microg/kg subcutaneously every 12 h was started on day 7. The initial idarubicin dose was 20 mg/m2 with dose escalations of 10 mg m2. Cohorts of three patients were treated at each idarubicin dose level. Unacceptable toxicity was encountered at 50 mg/m2 with one death from infection and one death from cardiotoxicity in a patient with significant prior anthracycline exposure. There were no instances of grade 4 non-hematologic toxicity encountered at idarubicin doses of 20 mg/m2, 30 mg/m2, or 40 mg/m2. The data suggest a dose-response relationship for increasing doses of idarubicin with 0/3 complete responses (CR) at 20 mg/m2, 1/3 CR at 30 mg/m2, and 7/12 (58%) CR at idarubicin doses > or = 40 mg/m2. We conclude that concomitant administration of cytarabine 3 g/m2/day x 5 and high-dose idarubicin at 40 mg/m2 as a single dose on day 3 can be administered safely to patients with refractory and relapsed ALL.     

A fearsome enemy (1); A history of sanitation in the British Army 1899-1914

This study presents the results of a prospective study of methyl-gag, ifosfamide, methotrexate and etoposide (MIME) as salvage regimen for Hodgkin's disease (HD) in Sweden. Sixty-four patients with recurrent or refractory HD were treated with MIME between July 1988 and December 1993. All patients except one had, earlier, been treated with and failed consecutive or alternating MOPP and ABVD. Median age was 37 yr (range 14-73). Twenty patients (31%) achieved a complete remission (CR) and 17 (27%) a partial remission (PR), giving an overall response rate of 58%. The 5-yr survival for all patients was 43%. In a multivariate analysis, the most important factors predicting a poor survival were the presence of extranodal disease at relapse, male gender and high age. Twenty-nine patients were treated with high-dose chemotherapy with stem-cell rescue after MIME. Those patients had a similar survival compared to the patients responding to MIME but not treated with high-dose chemotherapy. We conclude that MIME induces remissions in a high proportion of patients with recurrent and refractory HD with acceptable toxicity. The remissions probably need consolidation, but the nature of this consolidation is still controversial.     

Autologous bone marrow transplantation for acute myeloid leukemia using busulfan plus etoposide as a preparative regimen

We have studied the use of a new preparative regimen for the treatment of patients in remission of acute myeloid leukemia (AML) with autologous bone marrow transplantation. Chemotherapy consisted of busulfan 1 mg/kg every 6 hours for 4 days (total dose, 16 mg/kg) on days -7 through -4 followed by an intravenous infusion over 6 to 10 hours of etoposide 60 mg/kg on day -3. Autologous bone marrow, treated in vitro with 100 micrograms/mL of 4-hydroperoxycyclophosphamide, was infused on day 0. We have treated 58 patients up to the age of 60 years, 32 in first remission, 21 in second or third remission, and 5 with primary refractory AML unresponsive to high-dose Ara-C, but achieving remission with aggressive salvage regimens. Of the first remission patients, there has been 1 treatment related death and 5 relapses. With median follow-up of 22 months, the actuarial relapse rate is 22% +/- 9% and disease-free survival is 76% +/- 9% at 3 years. Patients with favorable French-American-British (FAB) subtypes (M3 or M4 EO) did especially well, with no relapses seen in 15 patients observed for a median of 30 months. Actuarial relapse rate at 3 years was 48% for first remission patients with less favorable FAB subtypes. Of patients in second or third remission, there were 5 treatment related deaths and 4 relapses. With median follow-up of 22 months, the actuarial relapse rate is 25% +/- 11% and disease-free survival is 56% +/- 11% at 3 years. Four of five primary refractory patients died during treatment and 1 remains in remission with short follow-up. These preliminary data are very encouraging and, if confirmed, support the use of autologous purged bone marrow transplantation using aggressive preparative regimens as one approach to improve the outcome of adults with AML.     

Transplant-lite: induction of graft-versus-malignancy using fludarabine-based nonablative chemotherapy and allogeneic blood progenitor-cell transplantation as treatment for lymphoid malignancies

PURPOSE: To investigate the use of a nonmyeloablative fludarabine-based preparative regimen to produce sufficient immunosuppression to allow engraftment of allogeneic stem cells and induction of graft-versus-leukemia/lymphoma (GVL) as the primary treatment modality for patients with chronic lymphocytic leukemia (CLL) and lymphoma. PATIENTS AND METHODS: Fifteen patients were studied. Six patients were in advanced refractory relapse, and induction therapy had failed in two patients. Patients with CLL or low-grade lymphoma received fludarabine 90 to 150 mg/m2 and cyclophosphamide 900 to 2,000 mg/m2. Patients with intermediate-grade lymphoma or in Richter's transformation received cisplatin 25 mg/m2 daily for 4 days; fludarabine 30 mg/m2; and cytarabine 500 mg/m2 daily for 2 days. Chemotherapy was followed by allogeneic stem-cell infusion from HLA-identical siblings. Patients with residual malignant cells or mixed chimerism could receive a donor lymphocyte infusion of 0.5 to 2 x 10(8) mononuclear cells/kg 2 to 3 months posttransplantation if graft-versus-host disease (GVHD) was not present. RESULTS: Eleven patients had engraftment of donor cells, and the remaining four patients promptly recovered autologous hematopoiesis. Eight of 11 patients achieved a complete response (CR). Five of six patients (83.3%) with chemosensitive disease continue to be alive compared with two of nine patients (22.2%) who had refractory or untested disease at the time of study entry (P = .04). CONCLUSION: These findings indicate the feasibility of allogeneic hematopoietic transplantation with a nonablative preparative regimen to produce engraftment and GVL against lymphoid malignancies. The ability to induce remissions with donor lymphocyte infusion in patients with CLL, Richter's, and low-grade and intermediate-grade lymphoma is direct evidence of GVL activity against these diseases. This approach appears to be most promising in patients with chemotherapy-responsive disease and low tumor burden.     

Progressive disease after ABMT for Hodgkin's disease

A major limitation of ABMT for relapsed/refractory Hodgkin's disease is disease recurrence post-transplantation. We retrospectively reviewed 68 patients undergoing ABMT from January 1987 to June 1993. All received a uniform preparatory regimen (CBV). The median patient age was 30; 75% received prior radiation therapy and all patients received prior chemotherapy. Thirty-one percent presented at the time of transplantation with tumor masses larger than 10 cm. Sixty-two percent received autologous marrow alone and 38% PBPC with or without autologous bone marrow. Overall and progression-free survival are 43 and 36% at 5 years. Median follow-up for survivors is 59 months. Multivariate analysis revealed that tumor bulk was the most powerful poor prognostic factor for both survival and progression-free survival. Those transplanted with non-bulky tumors had an overall survival and progression-free survival of 52 and 44%, respectively, compared to those transplanted with bulky tumors who had an overall survival and progression-free survival of 22 and 16% (P = 0.03 and P = 0.04, respectively). Twenty-seven patients have relapsed. Four relapsed more than 2 years after ABMT. Four of the 27 patients who have relapsed remain alive, two without evidence of disease. The time after transplant to relapse was prognostically important, with no patients who relapsed within 6 months of ABMT still being alive, compared with 25% of patients who relapsed 7 or more months after ABMT who are still alive. We conclude that salvage therapy for relapse after ABMT is appropriate, as some patients may achieve prolonged survival. The time from transplant to relapse is an important survival predictor.     

High-dose chemotherapy with carboplatin, etoposide and ifosfamide followed by autologous stem cell rescue in patients with relapsed or refractory malignant lymphomas: a phase I/II study

Patients with relapsed or refractory non-Hodgkin's lymphomas (NHL) and Hodgkin's disease (HD) with recurrences after an anthracyclin-containing regimen only have a chance of cure of below 10% with conventional chemotherapy. In order to improve their prognosis, we started a phase I/II trial using high-dose therapy comprising carboplatin, together with etoposide and ifosfamide (CEI), followed by autologous stem cell rescue (ASCR) as consolidation after salvage treatment. Since September 1990, 40 patients with intensively pretreated advanced NHL (n = 24) or HD (n = 16) received one cycle of high-dose therapy (HDT) consisting of carboplatin 1500 mg/m2, ifosfamide 10 g/m2 and etoposide in escalating doses from 1200 mg/m2 to 2400 mg/m2 followed by ASCR. Thirty-nine patients were assessable for toxicity and response. The following doses appeared to be safe: carboplatin 1500 mg/m2, etoposide 2400 mg/m2 and ifosfamide 10 g/m2. All patients developed grade 3 nausea and grade 3 or 4 mucositis. Granulocytopenic fever occurred in 100% with grade 4 infections in 15%. Mild transient kidney toxicity was noted in 36% and liver toxicity in 20% of patients. One toxic death occurred (2.5%). Objective responses were obtained in 36 of 39 patients (92%) with complete remissions (CR) in 24 patients (61.5%) and partial remissions (PR) in 12 (30.7%). Median observation time for surviving patients was 23.3 months (range 3.4-52.3). The probabilities of overall, event-free and relapse-free survival at 2 years are 62, 39 and 55%, respectively. Patients with primary refractory disease or resistant relapse had a poor prognosis. High-dose carboplatin, etoposide and ifosfamide plus autologous stem cell rescue represents an effective, potentially curative salvage treatment with acceptable toxicities.     

Quantification and localization of hyaluronan in a PTFE polymer implanted in the corneal stroma

OBJECTIVE: To determine outcome following treatment of refractory Crohn's disease with intravenous (i.v.) cyclosporine (CYA). METHODS: The medical records of 18 patients with refractory Crohn's disease treated with i.v. CYA were reviewed. Nine patients had refractory inflammatory Crohn's disease and nine patients had complex fistulizing Crohn's disease. All patients were initially treated with i.v. CYA (4 mg/kg/day). Patients who responded were converted to standard oral CYA. Patient outcomes were classified as complete response, partial response, or nonresponse. RESULTS: Four of nine patients with severe inflammatory Crohn's disease and seven of nine patients with fistulizing Crohn's disease had a partial response to i.v. CYA. Four of four responding patients in the inflammatory group and four of six responding patients in the fistulizing group (plus one initial nonresponder) maintained or improved their response during oral CYA therapy. After discontinuing oral CYA, all four patients in the inflammatory group and five of seven patients in the fistulizing group relapsed despite 1-17 wk of concomitant treatment with azathioprine or 6-mercaptopurine (AZA/6MP). Two patients who received overlapping CYA and AZA/6MP for 17 and 23 wk maintained long-term responses. CYA toxicity was minimal: reversible nephrotoxicity (n = 2), headache (n = 2), oral candidiasis (n = 1), paresthesia (n = 2). CONCLUSIONS: I.v. CYA appears to benefit both refractory inflammatory and fistulizing Crohn's disease. Most patients who respond to i.v. CYA will maintain their response during oral CYA therapy. However, the majority of these patients relapse when oral CYA is discontinued, probably because of inadequate duration of overlap with the slow acting maintenance drugs, AZA/6MP.     

Radiation therapy in the management of desmoid tumors

PURPOSE: To evaluate the outcome of patients with extra-mesenteric desmoid tumors treated with radiation therapy, with or without surgery. METHODS AND MATERIALS: The outcome for 75 patients receiving radiation for desmoid tumor with or without complete gross resection between 1965 and 1994 was retrospectively reviewed utilizing univariate and multivariate statistical methods. RESULTS: With a median follow-up of 7.5 years, the overall freedom from relapse was 78% and 75% at 5 and 10 years, respectively. Of the total, 23 patients received radiation for gross disease because it was not resectable. Of these 23 patients, 7 sustained local recurrence, yielding a 31% actuarial relapse rate at 5 years. Radiation dose was the only significant determinant of disease control in this group. A dose of 50 Gy was associated with a 60% relapse rate, whereas higher doses yielded a 23% relapse rate (p < 0.05). The other 52 patients received radiation in conjunction with gross total resection of tumor. The 5- and 10-year relapse rates were 18% and 23%, respectively. No factor correlated significantly with disease outcome. There was no evidence that radiation doses exceeding 50 Gy improved outcome. Positive resection margins were not significantly deleterious in this group of irradiated patients. For all 75 patients, there was no evidence that radiation margins exceeding 5 cm beyond the tumor or surgical field improved local-regional control. Ultimately, 72 of the 75 patients were rendered disease-free, but 3 required extensive surgery (amputation, hemipelvectomy) to achieve this status. Significant radiation complications were seen in 13 patients. Radiation dose correlated with the incidence of complications. Doses of 56 Gy or less produced a 5% 15-year complication rate, compared to a 30% incidence with higher doses (p < 0.05). CONCLUSIONS: Radiation is an effective modality for desmoid tumors, either alone or as an adjuvant to resection. For patients with negative resection margins, postoperative radiation is not recommended. Patients with positive margins should almost always receive 50 Gy of postoperative radiation. Unresectable tumors should be irradiated to a dose of approximately 56 Gy, with a 75% expectation of local control.     

Unexpected rhabdomyolysis with myoglobinuria in a patient in the supine position

BACKGROUND: The relapse rate after steroid induced remission in Crohn's disease is high. AIMS: To test whether oral pH modified release budesonide (3 x 1 mg/day) reduces the relapse rate and to identify patient subgroups with an increased risk of relapse. METHODS: In a multicentre, randomised, double blind study, 179 patients with steroid induced remission of Crohn's disease received either 3 x 1 mg budesonide (n = 84) or placebo (n = 95) for one year. The primary study aim was the maintenance of remission of Crohn's disease for one year. RESULTS: Patient characteristics at study entry were similar for both groups. The relapse rate was 67% (56/84) in the budesonide group and 65% (62/95) in the placebo group. The relapse curves in both groups were similar. The mean time to relapse was 93.5 days in the budesonide group and 67.0 days in the placebo group. No prognostic factors allowing prediction of an increased risk for relapse or definition of patient subgroups who derived benefit from low dose budesonide were found. Drug related side effects were mild and no different between the budesonide and the placebo group. CONCLUSION: Oral pH modified release budesonide at a dose of 3 x 1 mg/day is not effective for maintaining steroid induced remission in Crohn's disease.     

Outcome of Graves' disease after antithyroid drug treatment in Taiwan

The outcome of Graves' disease after treatment with antithyroid drugs (ATDs) varies widely among countries, and large-scale studies in Asia are rare. We investigated the associations of various clinical and laboratory features with the outcome of ATD therapy for Graves' disease in Taiwan. A total of 210 patients (177 women, 33 men; mean +/- SD age, 41.7 +/- 15.1 yr) treated with ATD in Taiwan were included. ATD therapy started with methimazole 30 mg daily or propylthiouracil 300 mg daily and was continued until a euthyroid state was achieved. Afterwards, 154 patients received a maintenance dose of ATD alone, while 56 patients received a combination of an ATD and thyroxine (L-T4). Patients were considered to be in remission if they remained in a euthyroid state for more than 2 years after drug withdrawal. The mean follow-up periods were 45.0 +/- 20.9 months for patients with remission and 30.4 +/- 19.8 months for those with relapse. Relapse occurred in 126 (60%) patients during the follow-up period, within 3 months after drug withdrawal in 47 (37%), and within 6 months in 60 (46%). The relapse rate was 100% among patients with two or more previous relapses. Patients with a second occurrence had a higher relapse rate than those with a first occurrence (84% vs 43%). Past history of recurrence, goiter size, thyroid-stimulating hormone level and thyrotropin-binding inhibition immunoglobulin activity at the end of ATD treatment were independently associated with relapse. Prolonged duration of treatment did not yield better results in patients with larger goiters or a history of recurrence, or both. Combination therapy with L-T4 yielded similar results to those achieved with ATD treatment alone. In conclusion, the relapse rate of Graves' disease after ATD treatment in Taiwanese patients was high, especially in those with a history of recurrence. The treatment duration and drug regimen did not affect the outcome.     

Effect of prostaglandin A1 on proliferation and telomerase activity of human melanoma cells in vitro

BACKGROUND AND OBJECTIVE: Idarubicin, an anthracycline analogue, is active in non-Hodgkin's lymphoma. This study evaluates the efficacy and toxicity of a combination of idarubicin, etoposide and intermediate-dose cytarabine (IVA) in unfavorable lymphoma in relapse or resistant to prior doxorubicin- or novantrone-based regimens. DESIGN AND METHODS: Thirty patients with relapsing or resistant unfavorable lymphoma received a combination of idarubicin 12 mg/m2 i.v. on day 1, etoposide 60 mg/m2 i.v. every 12 hours for 3 days, and Ara-C 1 g/m2 i.v. every 12 hours for 3 days (3-hour infusion). Median age was 39 years (range: 22-60). All patients had been given prior doxorubicin or novantrone; 54% of them had received 2 or more chemotherapy regimens; 67% of total were in clinical relapse (30% in their second relapse), and 23% had resistant disease. RESULTS: The overall response rate to IVA was 60% (18 of 30 patients). Complete remission rate was 20% (6 of 30) in the whole group, 45% (5 of 11) among patients in their first relapse. Remission median duration was 9 months (range: 1-18), with a 3-year relapse-free and overall survival of 20% and 15%, respectively. Severe neutropenia occurred in 13 patients (43%) and severe thrombocytopenia in 11 patients (37%), with a median duration of 9 and 13 days, respectively. No cardiac toxicity developed; sepsis during neutropenia was documented in four instances and two patients (7%) died of therapy-related events (septic shock). INTERPRETATION AND CONCLUSIONS: Idarubicin combined with etoposide and intermediate-dose cytarabine proved to be an active salvage therapy in unfavorable lymphoma given prior doxorubicin or novantrone; the best results were obtained among patients in their first relapse, with low tumor burden.     

Molecular analysis of Plasmodium vivax relapses using the MSP1 molecule as a genetic marker

PURPOSE: To evaluate radiation therapy regimens for improvement in local control in patients with limited-stage small cell lung cancer. MATERIALS AND METHODS: Radical radiation therapy results in 117 patients with limited-stage small cell lung cancer were retrospectively reviewed. The protocols in 90 patients were 40 Gy in 20 fractions (n = 28), 50 Gy in 25 fractions (n = 32), and 45 Gy in 30 fractions (accelerated hyperfractionation, n = 30). The other 27 patients received thoracic irradiation (dose range, 20-60 Gy; median dose, 54 Gy). All patients underwent systemic chemotherapy. RESULTS: The 5-year Kaplan-Meier survival rates in the patients with N0, N1, N2, and N3 disease were 26%, 34%, 18%, and 0%, respectively; the rates of in-field relapse were 25%, 36%, 26%, and 25%, respectively; and the rates of marginal relapse were 0%, 9%, 15%, and 29%, respectively. In 56% of patients with marginal relapse, the relapse site was at the upper margin. The 4-year in-field control rates for the patients who underwent 40, 50, and 45 Gy were 51%, 70%, and 56%, respectively. CONCLUSION: Patients with N3 limited-stage small cell lung cancer should undergo a separate protocol, and the upper margin should be extended in patients with N2 or N3 disease.     

Detection of relapse in early-stage Hodgkin's disease: role of routine follow-up studies

PURPOSE: To examine the costs and benefits of routine follow-up evaluation in patients treated with radiation therapy for early-stage Hodgkin's disease. PATIENTS AND METHODS: We retrospectively examined patterns of follow-up evaluation and methods of relapse detection among 709 patients with stage I and II Hodgkin's disease treated with primary radiotherapy between 1969 and 1994. We determined the probability of relapse detection for seven routine follow-up procedures, compared their relative costs, and determined the impact of each procedure on the likelihood of survival following salvage therapy. RESULTS: Relapse has occurred in 157 patients (22%) at a median 1.9 years (range, 0 to 13 years) posttreatment. Relapse was suspected primarily by history (Hx) in 55% of patients, physical examination (PE) in 14%, chest x-ray (CXR) in 23%, and abdominal x-ray (KUB) in 7%. Only one relapse (1%) was identified by a routine laboratory study. The rate of relapse detection was highest for a combination of Hx and PE (78 of 10,000 examinations) followed by CXR (26 of 10,000 examinations). The projected charges (1995 dollars) per relapse detected by routine follow-up Hx and PE were $11,000 compared with $68,000 for CXR and $142,000 for KUB. The 10-year actuarial survival rate following salvage therapy was 65% overall, 65% for patients in whom relapse was detected by Hx or PE, and 69% for patients in whom relapse was detected by radiographs (P = not significant). CONCLUSION: The majority of relapses occurred within 5 years of treatment and were identified by Hx and PE. CXR was useful during the first 3 years of follow-up evaluation. KUB, CBC, and laboratory studies accounted for nearly half of all follow-up charges and rarely led to the detection of relapse. Their routine use as a method of relapse detection is questionable. In general, the method of relapse detection did not have a significant impact on the likelihood of successful salvage therapy.     

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.     

Management and outcome of borderline ovarian tumors incidentally discovered at or after laparoscopy

OBJECTIVE: The optimal antithyroid drug regimen for Graves' disease remains a matter of controversy. The European Multicentre Trial Group has investigated the effects of methimazole drug dose on the long-term outcome of Graves' disease. DESIGN: Extended follow-up of patients from a prospective multicentre trial, designed to study methimazole dose effects on the outcome of Graves' disease. We have reported previously that the relapse rates did not differ after a medication-free observation period of 12 months; the relapse rates were 37% and 38%, respectively. In this paper, we describe the outcome in these patients after a mean observation period of 4.3 +/- 1.3 years and have looked for potential predictors of this outcome. PATIENTS: Three hundred and thirteen patients with Graves' disease were randomized to treatment with a constant dose of 10 or 40 mg of methimazole for 1 year, with levothyroxine supplementation as required. MEASUREMENTS: At the time of inclusion into the trial: thyroid size, T4, T3, TSH-binding inhibiting immunoglobulins, urinary iodide excretion, thyroid uptake, Crook's therapeutic index of hyperthyroidism (a measure of clinical disease severity). At the time of follow-up examination: TSH, T4, T3, thyroid size, thyroid ultrasound, THS-binding inhibiting immunoglobulins. RESULTS: The overall relapse rate was 58%. There was no difference in relapse rates between patients treated with either 10 or 40 mg of methimazole (58.3 vs. 57.8%). Five patients had become spontaneously hypothyroid, without obvious relationship to antithyroid drug dose. Patients who relapsed and patients who remained in remission did not differ with respect to: age, goitre size, ophthalmopathy, median iodine excretion, serum T4 or serum T3, Crook's therapeutic index and thyroid uptake at the time of study entry. Thus, none of these variables was potentially suitable for predicting outcome. This finding was confirmed by Cox's proportional hazard regression. Thyroid volume, measured by ultrasound, did not differ between patients in remission and patients with relapse. There was no difference in the course of endocrine eye signs, in the requirement for steroid and radiotherapy for eye signs, or in thyroid echostructure between patients in the 10 and in the 40 mg group, nor was serum TSH different in patients who had remained in remission (0.8 +/- 0.6 mU/l in the 10 mg group, 1.0 +/- 0.8 mU/l in the 40 mg group). CONCLUSIONS: The dose of methimazole in Graves' disease therapy can safely be kept to the minimal required dose. This will provide the same chance of remission as higher doses, and provide the best balance of risk and benefit.     

BEAM chemotherapy followed by autologous stem cell support in lymphoma patients: analysis of efficacy, toxicity and prognostic factors

In the present paper, we evaluate tolerability, outcome and prognostic factors in patients with poor prognosis non-Hodgkin's lymphoma (NHL) and Hodgkin's disease (HD) when uniformly treated with BCNU, etoposide, cytarabine and melphalan (BEAM) and autologous stem cell transplant (ASCT). On hundred and forty-eight patients with NHL (n = 112) or HD (n = 36) received BEAM followed by infusion of bone marrow (n = 55), peripheral blood stem cells (n = 79) or both (n = 14). Twenty-eight patients had low-grade lymphoma (LGL), 68 intermediate- and 16 high-grade lymphoma (IGL). Within the NHL group, 21 patients were in 2nd or subsequent complete remission (CR) at transplant, 34 had sensitive disease and 11 resistant disease; 46 patients were transplanted in 1st CR due to the presence of > or = 2 adverse prognostic features at diagnosis or to a slow CR. Of the HD patients at transplant 17 had active disease, 16 were in > or = 2 CR and three in 1st CR. The overall percentage of toxic deaths was 5.4%, while in the group of patients transplanted with PBSC it was only 1.3%. NHL patients: 78% were in CR following ASCT, including 25 out of 45 patients (56%) who were transplanted with active disease. Only two of the 11 patients transplanted with resistant disease achieved CR. Incidence of overall survival (OS) and disease-free survival (DFS) at 3 years was 65 and 75%, respectively. As far as histology was concerned, OS was significantly better for patients with LGL in comparison with IGL (88 vs 56%) (P = 0.002). DFS was significantly higher for patients transplanted in first CR or first partial remission (PR) than it was for those transplanted in a later CR or PR (86 vs 53%) (P = 0.02). Multivariate analysis for OS showed that histology, bulky disease, poor performance status at transplant and achievement of CR were independent prognostic factors. In addition, a high number of infused MNC was associated with poor DFS. HD patients: 30 (83%) were in CR after transplantation, with 25 maintaining CR at the end of the study. Only one of the four patients transplanted with resistant disease reached CR. Incidence of OS and DFS at 3 years was 78 and 81%. DFS was similar for patients transplanted with early or late relapse (95 and 93%). With multivariate analysis, the only independent variable for OS was CR after transplant. In conclusion, the present results demonstrate the efficacy and low toxicity of the BEAM regimen in high-risk lymphoma patients with sensitive disease. Other strategies should be investigated for patients with refractory lymphoma.
