Abstract
We previously reported a 50% (95% CI = 33-76%) 5 year event-free survival (EFS) rate for 23 patients with Hodgkin's disease (HD) who received salvage therapy with single agent high-dose melphalan (HDM) and autologous stem cell transplantation (ASCT). Predictors of poor outcome included bulky disease and initial remission <1 year. Since 1995, similar poor prognosis patients have been treated with double high-dose therapy consisting of dose-intensive cyclophosphamide 5.25 g/m2, etoposide 1.05 g/m2, cisplatin 105 mg/m2 (DICEP) for tumor cytoreduction and stem cell mobilization followed by HDM/ASCT. The purpose of the present study is to determine if the use of DICEP is associated with improved event-free (EFS) and overall survival (OAS) for patients treated with HDM/ASCT. From February 1981 to June 1999, 46 consecutive patients received HDM/ASCT for relapsed (n = 35) or refractory (n = 11) HD. DICEP re-induction and blood stem cell mobilization was used for 21 patients. Factors considered for univariate and multivariate analyses included age at transplant, number of failed chemotherapy regimens, prior radiotherapy, length of initial remission, relapsed or refractory disease status, extranodal relapse, B symptoms at relapse, bulk, post-ASCT radiotherapy, and DICEP re-induction therapy. Cox proportional hazards models were constructed for both event and death. DICEP and HDM were well tolerated with no early treatment-related mortality or toxicity requiring life-sustaining measures. For all 46 patients, the projected 5 year EFS was 52% (95% CI = 38-72%) and OAS was 57% (95% CI = 40-82). Factors independently associated with relapse in multivariate analysis included bulk >5 cm (RR = 6.38, P = 0.002), prior radiotherapy (RR = 3.59, P = 0.027), and not using DICEP (RR = 5.29, P = 0.005). Factors independently associated with death included bulk >5 cm (RR = 5.13, P = 0.009), > or =3 prior chemotherapy regimens (RR = 4.72, P = 0.019), and not using DICEP (RR = 7.49, P = 0.015). This study demonstrates that DICEP re-induction prior to HDM/ASCT is feasible. The preliminary data are sufficiently encouraging to warrant a multicenter phase II or a phase III trial evaluating DICEP followed by HDM/ASCT as salvage therapy for HD.

Abstract
To determine the optimal treatment volume in Hodgkin's disease patients undergoing high-dose chemotherapy (HDCT) and radiation therapy (RT), failure sites were reviewed in 56 patients. Twenty-one (38%) received involved-field RT (IFRT) before or after HDCT encompassing sites of prior disease. Failure sites were designated as previously involved (old) or uninvolved (new) sites. Seven patients (12%) died in the immediate post-HDCT period, leaving 49 evaluable (median follow-up, 41 months). Twenty-five patients (51%) relapsed (14 HDCT, 11 HDCT + IFRT): seven (28%) in old, eight (32%) in new, and ten (40%) in old and new sites. Six of the seven who relapsed in old sites received HDCT alone, whereas seven of the eight who relapsed in new sites received IFRT. Relapse in old sites was particularly common in patients failing to achieve a complete response. The most common new failure site was nodal, occurring in 11 patients and was primarily (10/11) adjacent to an old site. Although it controls prior disease, IFRT is insufficient in Hodgkin's disease patients undergoing HDCT. Relapse is common in new nodal sites and is primarily adjacent to prior sites. These results suggest that extended-field RT encompassing old and adjacent uninvolved nodal sites may be the optimal treatment volume in these patients.

Abstract
BACKGROUND Few data are available on the cost, safety, and long-term efficacy of single-agent high-dose melphalan (HDM) followed by autologous bone marrow (ABMT) or blood stem cell (ABSCT) transplantation in the salvage therapy of Hodgkin's disease (HD). PATIENTS AND METHODS From February 1981 to September 1996, 23 patients with relapsed (n = 15) or refractory (n = 8) HD received salvage therapy with HDM 140-200 mg/m2 followed by non-cryopreserved ABMT (n = 18) or cryopreserved ABSCT (n = 5). The cost of HDM/ABSCT in 1996, from initial consultation until transfer back to referring physician, was determined and compared to the estimate costs of two multi-agent regimens commonly used for HD. RESULTS HDM was well tolerated with no early transplant-related mortality. The five-year overall and progression-free survival rates were 52% and 50%, respectively. The average total cost in Canadian funds of HDM/ABSCT in 1996 was $34,400/patient. This cost was estimated to be $4,700-6,800 cheaper per patient than the multi-agent high-dose regimens. CONCLUSION These data suggest that HDM is safe, feasible, active, and reasonably inexpensive salvage therapy for patients with relapsed/refractory HD.

Abstract
Autologous bone marrow transplantation (ABMT) has been proposed as an alternative treatment of resistant/refractory Hodgkin's disease (HD). Thirty-seven patients in various phases of HD underwent autografting in our Center: fourteen received a CBV conditioning regimen, the others BCNU or VP16 followed by cyclophosphamide and TBI. Three patients died before engraftment, 28 (75.67%) achieved CR and 6 showed persistent disease. As of March 1996, 18 patients had died and 13 were in continuous CR. The median event-free survival (EFS) and 3-year EFS chances were respectively 9 months and 31.3% in the series as a whole, 14 months and 40% in primary resistant disease, 9 months and 28.4% in responsive relapse, and 3 months and 22.2% in resistant relapse. As many of these patients had failed to respond to third-line therapies, their EFS figures are primarily attributable to the therapeutic efficacy of ABMT. Furthermore, since the EFS curves are better in patients seemingly characterized by a lower chance of chemoresistance, our data favour the use of ABMT in the earlier phases of HD.

Abstract
In a hospital-based case-control study of endometrial cancer undertaken in Athens (1992-94), 145 women residents of Greater Athens with confirmed cancer of the endometrium were compared with 298 control patients with orthopaedic diseases. Personal interviews were conducted in the hospital setting, and diet was assessed using a validated semiquantitative food frequency questionnaire. Nutrient intakes for individuals were calculated by multiplying the nutrient intake of a typical portion size for each specified food item by the frequency at which the food was consumed per month and summing these estimates for all food items. Data were modelled through logistic regression, controlling for demographic, reproductive and somatometric risk factors for endometrial cancer as well as for total energy intake. No macronutrient was significantly associated with endometrial cancer risk, but increasing intake of monounsaturated fat, mostly olive oil, by about one standard deviation was associated with a 26% risk reduction (odds ratio = 0.74; 95% confidence interval 0.54-1.3). Among micronutrients, only calcium intake was significantly inversely associated with endometrial cancer risk, whereas there was evidence against retinol and zinc imparting protection against the disease. With respect to food groups, there was weak and non-significant evidence that vegetables are protective, whereas consumption of pulses was positively associated with disease possibly because they contribute substantially in Greece to energy intake in excess of physical activity-dependent requirements.

Abstract
High-dose chemotherapy with autologous bone marrow transplantation is used in the treatment of relapsed or high-risk Hodgkin's disease. As prospective randomised studies have proved difficult to accrue to, current recommendations are based on the reports of large series of prospectively collected data. We have looked at the outcome of 89 patients treated in this way at a single institution and have developed an index to predict outcome. Of 89 patients, with a median age of 29 years (range 15-51 years), eight patients were in first complete remission/partial remission (CR/PR), 17 in second or later CR, 37 were responding relapses, 13 resistant relapses, 11 primary refractory and three untested relapses. Combinations of melphalan, BCNU and etoposide were given in all cases except in ten patients who received melphalan alone. The median follow-up was 43 months (range 6-77 months). A total of 24 patients were in CR at the time of autologous bone marrow transplantation (ABMT), 33 achieved CR with ABMT, 16 PR, to give a response rate to ABMT of 49/65 = 74% (95% CI 60-83%) with a CR rate of 51% (CI 36-62%). In a Cox's multivariate analysis the most important factors in predicting outcome after ABMT were response to treatment before entry, number of previous treatments and previous chemosensitivity. Using these factors we devised a prognostic index which reliably selects a group of patients (65%) with at least a 70% chance of being progression free from 1 year onwards. Patients who have never achieved a CR and have received three or more chemotherapy regimens do not benefit from high-dose chemotherapy as used in this study.

Abstract
We report the experience of three French centres which evaluated high-dose therapy (HDT) as consolidation therapy for poor prognosis Hodgkin's disease (HD). From March 1986 to April 1990, 23 consecutive patients with poor prognosis stage IV HD underwent HDT followed by autologous bone marrow transplantation (ABMT) after achieving either complete remission (CR1) or good partial response (GPR1) (reduction mass> 75%). The median age was 31 years (range 18 to 55 years), 14 were male. All patients except one initially had at least 2 poor prognosis factors such as: systemic symptoms (n = 19), bulky tumor (n = 16), more than one extranodal site (n = 9), bone marrow involvement (n = 5), lymphocyte count < or = 1.10(9)/1 (n = 8) and biological stage B (n = 21). All patients had previously been treated with alternating MOPP/ABVD. Ten patients were in GPR1 and 13 in CR1 before transplant. The conditioning regimens were: CBV (n = 17), BEAM (n = 5), BEAC (n = 1) followed by bone marrow rescue. Radiotherapy was introduced just before the conditioning regimen for 6 patients or after ABMT for 5 patients. Nine of 10 patients in GPR1 achieved CR after ABMT but one died early of treatment-related toxicity. Five of 22 patients who were in CR posttransplant, relapsed (3, 4, 4, 18, 36 months). Seventeen patients remain alive in continuous CR with a median follow-up of 60 months (range: 30-100 months). The overall survival (OS) and disease-free survival (DFS) projected at 5 years are 92% and 77% respectively. Consolidation by HDT and ABMT proved to be well tolerated. An international trial is currently underway to attempt to demonstrate a clear benefit on survival for this subset of poor prognosis HD patients.

Abstract
PURPOSE A retrospective review evaluated the results of autologous bone marrow transplantation (A-BMT) for patients with relapsed Hodgkin's disease (HD) who were potentially treatable by radical radiation therapy (RRT). METHODS AND MATERIALS Evaluated patient cases met the following criteria: initial treatment with chemotherapy (with or without involved field radiation therapy < 25 Gy); no history of bone marrow or extensive lung involvement; no current or previous evidence of systemic metastases except liver; radiation therapy used with salvage chemotherapy for prior relapse would not preclude use of RRT (e.g., > 20 Gy to spinal cord); HD at time of salvage therapy limited to lymph nodes, Waldeyer's ring, liver, spleen, direct extension sites, and/or one lung. RESULTS There were 23 A-BMT patients treated between 1986 and 1991 who fulfilled the criteria. Three (13%) patients died from treatment-related complications and eight (35%) developed nonfatal Grade 3-4 complications. The 3-year actuarial disease-free survival rate was 61%. The 3-year disease-free survival rate was 55% for the nine patients with at least one prior disease-free interval (DFI) > 12 months, 67% for nine patients with DFI < 12 months, and 60% for five induction failure patients (p > 0.10). These results are comparable to retrospective studies of RRT results in selected relapsed HD patients. CONCLUSIONS Long-term disease-free survival is frequently possible with either A-BMT or RRT in appropriately selected relapsed HD patients. In considering treatment options, important prognostic factors include initial stage of disease, number of prior relapses, DFI, and extent of relapsed disease.

Abstract
From 1986 through 1992, involved-field radiation therapy (IF-RT) was administered to 29 of 86 patients with recurrent Hodgkin's disease (HD) who received a high-dose cyclophosphamide/etoposide regimen with autologous bone marrow transplantation (A-BMT). Patients without a significant history of prior RT received total body irradiation (TBI), initially as a single dose 5-7.5 Gy, and subsequently with fractionated TBI (F-TBI) delivering 12 Gy. Previously irradiated patients received a high-dose BCNU regimen instead of TBI. IF-RT was employed selectively, usually for sites of bulky disease (> 5 cm). IF-RT doses were typically 20 Gy at 2 Gy per fraction for TBI patients and 30-40 Gy at 1.8-2.0 Gy per fraction for non-TBI Patients. Fatal complications developed in four patients while second malignancies have developed in two. The region which received IF-RT was the site of first recurrence in only two cases (7%). With a median follow-up of 28 months, the two-year disease-free survival rate was 44%. For the 22 patients treated by either F-TBI or high-dose BCNU, the 2-year disease-free survival rate was 50% with a median follow up of 29 months. Selective use of IF-RT may increase the chances of complete remission and disease free survival in HD patients with a history of bulky disease.

Abstract
PURPOSE A study was performed to determine the effectiveness of radical radiation therapy (RT) in the treatment of patients with Hodgkin's disease who relapsed following initial treatment with chemotherapy alone. METHODS AND MATERIALS A retrospective review of patients treated at City of Hope National Medical Center between 1970 and 1987 revealed a total of 10 patients who received radical RT with curative intent as salvage therapy. RESULTS Complete remission was achieved in eight of the ten patients. Patients had an overall 5-year actual survival of 60% and 10-year actuarial survival of 38%. Relapse-free survival was 30% at 5 years and at 10 years. For the five patients with a disease-free interval (DFI) of at least 12 months prior to radical RT, overall actual survival at 5 years was 100% and relapse-free survival was 60%. Three of the ten patients, all with a DFI > 12 months and in first relapse when undergoing radical RT, were long-term relapse-free survivors. CONCLUSION Radical RT is an effective salvage regimen for select patients with advanced stage Hodgkin's disease who relapse following initial treatment with chemotherapy alone provided that relapse is limited to sites which can be encompassed by radical RT fields and the DFI is greater than 12 months. Review of other published series supports DFI > 12 months as a favorable prognostic factor. Comparison to other salvage regimens such as autologous bone marrow transplantation is limited. Reviews of other treatment modalities should perform subset analysis on patients with similar presentations to compare the relative effectiveness of various salvage approaches.

Abstract
Most patients with Hodgkin's disease (HD) are cured with chemotherapy and/or radiotherapy. However, half of those with advanced stage disease (IIIB, IV) do not respond adequately to treatment or relapse. Salvage therapy used in such cases gives from 10% to 50% complete remission but only 10% long term survival. The results of bone marrow transplantation reported in acute leukemia and non-Hodgkin's lymphoma encouraged some authors to develop this new therapeutic strategy in Hodgkin's disease. In the early 1980's promising results were achieved when refractory and relapsed patients were selected to receive myeloablative therapy followed by bone marrow transplantation. Today, high dose chemotherapy with hematopoietic stem cell transplantation (HSCT) is used more and more often in poor prognosis Hodgkin's disease. After a review of the literature concerning the results of transplantation in Hodgkin's disease, we develop the numerous problems associated with this procedure which remain to be solved such as: the optimal indication, the timing of HSCT, the type of graft, the conditioning regimen, the place of radiotherapy and the optimal use of hematopoietic growth factors. We conclude with future prospects.

Abstract
17 patients with recurrent Hodgkin's disease received 21 courses of radiotherapy (RT) 1-23 months after high-dose chemotherapy and autologous bone marrow transplantation. WHO grade III-IV haematological toxicity, of median duration 38 days (range 4-236), was observed following 10 courses of radiotherapy in 9 patients. This haematological morbidity could be predicted with an 80.0% sensitivity when the pre-RT white cell count was < 5 x 10(9)/l or the platelet count < 100 x 10(9)/l. It occurred in 9/11 patients with initial stage III-IV disease, including all 6 given extended radiotherapy fields, but in no patients with initial stage II disease (chi 2 = 9.35, P < 0.005). Age, histology, the presence of B symptoms, performance status, previous radiotherapy or chemotherapy, the interval between autologous bone marrow transplantation and radiotherapy, the high-dose regimen used, and the radiotherapy dose or field size, did not appear to affect haematological toxicity. The median survival was 18 months from the date of starting radiotherapy. 7 patients remain alive and progression-free 8-51 months (median 21 months) after radiotherapy. Radiotherapy may contribute to durable remissions in patients with relapsed or residual Hodgkin's disease after autologous bone marrow transplantation, but significant haematological toxicity may be expected in those with mild pancytopaenia prior to radiotherapy, particularly with initial stage III or IV disease.
