MOPP chemotherapy versus extended-field radiotherapy in the management of pathological stages I-IIA Hodgkin's disease.

In order to assess whether mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) chemotherapy (CT), which is less expensive and more easily available than radiotherapy (RT), is at least as effective as RT in terms of cure rate and has less iatrogenic damage, 89 consecutive patients with Hodgkin's disease (HD) (pathological stage I-IIA) were randomly allocated to receive mantle plus lumbar bar RT (36-45 Gy) or CT (six courses of MOPP). Forty-five patients were entered in the RT group and 44 in the CT group. The median follow-up was 60 months. Complete remission (CR) was obtained in all patients in the RT group and in 40 of 44 patients in the CT group. Overall survival (OS) and disease-free survival (DFS) were, respectively, 87.2% and 72.7% in the CT group and 93.5% and 74% in the RT group. Survival probability of relapsing patients was 76% for the patients in the RT group and 45% in the CT group. Treatment-related complications were more severe in the CT group as compared with the RT group.

Extended-field radiotherapy is superior to MOPP chemotherapy for the treatment of pathologic stage I-IIA Hodgkin's disease: eight-year update of an Italian prospective randomized study.

PURPOSE: To compare the effectiveness of chemotherapy (CHT) with extended-field radiotherapy (RT) in the treatment of early-stage Hodgkin's disease (ESHD), we report an 8-year updated analysis of a study in which treatment with six cycles of mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) CHT was randomly compared with extended-field RT. PATIENTS AND METHODS: From August 1979 to December 1982, 89 adult patients with pathologic stage I-IIA Hodgkin's disease (HD) were randomly allocated to receive either RT with mantle field followed by periaortic irradiation (n = 45) or six monthly courses of MOPP CHT (n = 44). RESULTS: All patients in the RT arm and 40 of 44 in the CHT arm achieved complete remission. Twelve relapses occurred in each group. Eight patients treated with MOPP and two of the RT arm died of HD. Three other patients of the CHT group died because of a second cancer. With a median follow-up greater than 8 years, the overall survival rate is significantly higher in the RT than in the CHT group (93% v 56%; P less than .001), whereas the rates of freedom from progression and relapse-free survival (RFS) were similar in the two groups (76% v 64% and 70% v 71%, respectively). Of the 12 patients relapsing after RT, 11 (92%) achieved a second CR, compared with only six of the 12 (50%) in the MOPP group. Analysis of the response rate to salvage treatments showed that the type of relapse in the MOPP group was a prognostic indicator for the achievement of a second CR, whereas in the RT group, a second CR was obtained regardless of the characteristics of the relapses. At 80 months, the probability of survival of relapsing patients calculated from time of relapse was 85% and 15% in the RT and CHT groups, respectively (P = .02). CONCLUSION: We conclude that RT alone is the treatment of choice for adult patients with ESHD with favorable prognostic factors.

Nine years' experience with ABMT in 128 patients with Hodgkin's disease: an Italian study group report.

One-hundred, twenty-eight patients with Hodgkin's disease in remission or who had failed a mechlorethamine, vincristine, procarbazine and prednisone (MOPP), a doxorubicin, bleomycin, vinblastine and dacarbazine (ABVD) and/or lomustine, etoposide and prednimustine (CEP) regimens have been treated with a high-dose therapy (HDT) containing cyclophosphamide, etoposide, carmustine (CVB) and autologous bone marrow transplantation (ABMT). Forty patients were treated while they were in resistant or progressive disease states using alternating MOPP/ABVD protocol; 15 patients received ABMT in first relapse; 51 patients had a complete remission (CR) with first-line therapy but later relapsed and then received conventional salvage therapy; 16 achieved no response or progression ("resistant relapse" patients) and 35 responded partially or completely ("sensitive-relapse" patients). The other 22 patients received ABMT in remission. Following HDT, 56 patients (52.8%) achieved CR and 23 patients (21.6%) achieved a partial remission for an overall response rate of 74.4%. Sixteen patients failed to respond and died in progressive disease 1 to 10 months (median 6 months) after ABMT. High-dose therapy produced severe toxicity including vomiting (100%), mucositis (75%) and liver enzymes and alkaline phosphatase elevations (51%). There were 10 treatment-related deaths. A multivariate analysis identified poor performance status and resistant-relapse patients as very important adverse risk factors for survival immediately after ABMT. These results, while validating this procedure for inducing remissions in advanced highly-treated patients, at the same time confirm the need of employing this approach in first relapse or in second complete remission after standard therapy and before ABMT or, in first complete remission in very high risk Hodgkin's disease patients. Our experience in 15 very poor prognosis Hodgkin's disease patients transplanted in first CR demonstrated to be much significant.

Evaluation of therapeutic modalities in the control of Hodgkin's disease.

The results achieved in three different studies carried out on patients affected by Hodgkin's disease are discussed. In study No. 1, 58 patients with pathological Stage I-II were treated with only a "Mantle" field irradiation. The complete remission (CR) rate was 98% with an actuarial overall survival of 90%, and a median of follow-up of 80 months. Thirty-one percent of patients relapsed. In study No. 2, 42 patients were randomly allocated to receive only MOPP chemotherapy versus extended field irradiation; CR rate was 68 and 95%, respectively (p less than 0.05). The overall survival rate was 100% in the radiotherapy group and 82% in the MOPP group. No relapses have been observed in patients treated with MOPP. In study No. 3, 218 patients affected by advanced Stage HD were randomly treated with 6 cycles of MOPP chemotherapy versus 6 cycles of ABVD chemotherapy. In the MOPP group the CR rate, the relapse-free survival rate (RFS), and overall survival (OS) rates at 60 months were 77, 68, and 76% respectively, whereas, in the ABVD group the CR, the RFS, and OS rates at 60 months were 75, 77 and 80% respectively, (p less than 0.05). These data and statistical comparisons are analyzed.

Surgical approach to isolated mediastinal lymphoma.

With the aim of assessing the role of surgery in the management of isolated mediastinal lymphoma, we have reviewed the data of 123 operations performed on 102 patients (64 with Hodgkin's disease and 38 with non-Hodgkin's lymphoma). One death and four major complications occurred in these patients. Macroscopically radical resection was performed in 14 patients who are free of disease after 1 to 14 years. Debulking resection was performed in five patients: Three are alive after 5 to 11 years and two died after 36 and 40 months. Ten patients (seven with non-Hodgkin's lymphoma and three with Hodgkin's disease) had residual mediastinal masses of more than 2 cm after chemotherapy; to assess the nature of the lesion (fibrosis or residual disease), we subjected these patients to surgical restaging of the mediastinum: Results were negative in seven and positive in three. We conclude that open biopsy is indispensable to obtain good tissue specimens suitable for histologic and immunohistochemical assessment. Biopsy must be performed as a major surgical procedure to avoid reoperation: Mediastinoscopy and sternal splitting incisions proved the most reliable approaches. Locally radical or debulking resection might be considered in selected cases to enhance long-term results.

Luteinizing hormone pulsatility and computer-assisted analysis of sperm features in patients with Hodgkin's disease.

The aim of this work was to characterize further the impairment of the reproductive function reported in untreated male patients with Hodgkin's disease. We evaluated the pattern of luteinizing hormone pulsatility and unconventional sperm features by computer-assisted sperm analysis (CASA) in 20 adult patients affected by biopsy-proven Hodgkin's disease before they were submitted to any therapeutic approach. Changes of luteinizing hormone pulsatility were documented and consisted mainly in an increase in pulse number in comparison with control subjects (P < 0.05). On CASA, 1/3 of the patients showed a reduction in the sperm number but, when motility, velocity and linearity of progression were evaluated, the number of patients with seminal alterations rose to 2/3. Sperm velocity and linearity were already impaired in stages I and II, whereas sperm number was reduced only in stage III. Symptomatic patients, regardless of the stage, showed a significant deterioration of all parameters. Our study supports the view that in Hodgkin's disease, before any treatment, a disorder of the reproductive system is present, both at hypothalamic/hypophysial and the gonadal level, having a pathogenesis that deserves to be elucidated by further study.

Hodgkin/Reed-Sternberg cells and Hodgkin's disease in patients with B-cell chronic lymphocytic leukaemia: an immunohistological, molecular and clinical study of four cases suggesting a heterogeneous pathogenetic background.

We report the immunohistological, molecular and clinical findings in four patients affected by B-cell chronic lymphocytic leukaemia (CLL) who developed "Richter's syndrome with Hodgkin's disease (HD) features" or "CLL with Hodgkin's transformation", all characterised by the presence of typical Hodgkin/Reed-Sternberg (H/RS) cells in lymph node biopsies. In three cases the nodal involvement by CLL was demonstrated both by the presence of a predominant background of CD5/CD19/CD23+ small lymphocytes and an IgH monoclonal rearrangement revealed by PCR analysis. Conversely, in the remaining case there was neither immunohistological nor molecular evidence of lymph node involvement by CLL. In all four cases H/RS cells were Epstein-Barr virus (EBV) latent membrane protein (LMP-1) positive. These findings suggest that the presence of H/RS cells in the first three patients, who had CLL/HD nodal involvement, might be related to transformation or clonal evolution of CLL cells in H/RS cells, which is in keeping with use of the term "CLL with Hodgkin's transformation". In the fourth case a de novo HD may be postulated, representing a second malignancy presumably not clonally related to CLL. In all cases a key pathogenetic role of EBV is suggested by the expression of LMP-1 in H/RS cells. Our findings indicate that the presence of typical H/RS cells in lymph node biopsies in CLL patients may reflect a heterogeneous pathogenetic background. The different clinico-pathologic settings should be taken into consideration because of their possible implications for patients' treatment and prognosis.

Intermediate stage Hodgkin's disease: preliminary results on 210 patients treated with four ABVD chemotherapy cycles plus extended versus involved field radiotherapy.

BACKGROUND: To improve long-term survival by reducing toxicity in intermediate stage Hodgkin's disease patients, we compared the effects of involved field (IF) versus extended field (EF) irradiation administered after four cycles of ABVD regimen. MATERIALS AND METHODS: Two hundred and ten Hodgkin's disease patients, at clinical stage II with risk factors and III without risk factors, were enrolled in the randomized study HD94. After four courses of ABVD regimen, patients who achieved complete remission (CR) or partial remission (PR) were randomly assigned to the IF or EF arm. The Kaplan-Meier method was adopted to estimate overall survival (OS) and relapse-free survival (RFS). RESULTS: After a median follow-up of 78 months (range 13-111 months), OS was 98% and 96%, respectively, in the EF and IF arms; RFS was 94% and 91%, respectively, in the EF and IF arms. CONCLUSION: We confirm the efficacy of four cycles of ABVD regimen, with suitable dose intensity, and radiotherapy as consolidation therapy, in intermediate stage Hodgkin's disease patients (CR = 99.5% and OS = 95%). We also found that involved field radiotherapy results were as effective as extended field, without acute toxicity.

MOPP treatment of resistant Hodgkin's disease following ABVD failure.

Fourteen patients with Hodgkin's disease resistant to ABVD were treated with MOPP chemotherapy (nitrogen mustard, vincristine, procarbazine, prednisone). Complete remission was obtained in 6 patients (43%). Four of the 6 complete responders are disease free after 5, 20, 23, 35 months. The actuarial median survival after MOPP of all patients is 20 months. These data confirm that there is no "cross-resistance" among the drugs included in the two schedules.

Technetium-99m tetrofosmin imaging in malignant lymphomas.

AIMS: To assess the utility of 99mTc tetrofosmin (TF) scintigraphy as a diagnostic modality in lymphomas. METHODS: Seventeen patients (14 with Hodgkin's disease and three with non-Hodgkin's lymphomas; age range, 10-59 years) were investigated. Planar and SPECT images of the supradiaphragmatic region (including neck and chest) were obtained. All patients were untreated at the time of the first scintigraphy. Follow-up scans after therapy were acquired in six patients (in five twice), so a total of 28 scintigraphic studies were performed. Mediastinal, pulmonary, cervical, supraclavicular and axillary activity was evaluated and results were compared in a blinded fashion with those of CT. RESULTS: TF imaging demonstrated pathological focal uptake at 38 sites (16 in the mediastinum, eight in the lungs, four in the axillae, eight in the supraclavicular region and two in the cervical region) in 16 of 17 untreated patients. CT identified 24 lesions (16 in the mediastinum, two in the lungs, two in the axillae, two in the supraclavicular and two in the cervical region) in 17 patients. Scintigraphy detected 22 of the 24 lesions demonstrated by CT and revealed 16 unknown tumor sites in 10 patients. The only negative pre-treatment scintigraphy result was found in a patient with axillary lymph node involvement. On the first post-treatment scintigrams there was a reduction in the number of visualized pathological sites (seven vs 16) in five of the six patients examined. The second follow-up study demonstrated only two lesions in two of the five patients examined. CONCLUSIONS: Our preliminary results indicate that TF imaging is effective in depicting supradiaphragmatic lymphoma lesions in untreated patients and suggest that serial scintigraphic studies may be suitable for monitoring response to treatment. However, larger series are needed to better define the possible role of TF scintigraphy in the follow-up of the response to therapy.

Hodgkin's disease stage I and II with exclusive subdiaphragmatic presentation. The experience of the Departments of Radiation Oncology and Hematology, University "La Sapienza" of Rome.

During the period 1978 to 1994, 1054 patients with Hodgkins's disease were evaluated and treated at the Departments of Radiation Oncology and Hematology, University "La Sapienza", Rome. A total of 549 patients presented with clinical or pathological stage I and II; 37 of these had Hodgkin's disease below the diaphragm (BDHD), and 512 above the diaphragm (ADHD). A comparison of patients with BDHD versus those with ADHD showed that the first group had a higher male to female ratio. A comparison of cases with stage II BDHD versus those with stage II ADHD showed that patients with BDHD were older (48 years vs 28 years), had different histologic features and a higher incidence of systematic symptoms (67% vs 33%). Stage II BDHD patients had a worse prognosis; in fact, there were significant differences in the overall survival and relapse-free-survival rates for cases with stage II BDHD versus those with stage II ADHD (overall survival, 46% vs 80%, P<0.001; relapse-free survival, 44% vs 69%, P<0.005). Stage was found to be the most important prognostic factor for BDHD cases without systematic symptoms treated with radiation therapy alone. The type of infradiaphragmatic presentation (intra-abdominal vs peripheral disease) did not influence outcome, probably due to the more aggressive therapy received by the intra-abdominal group. Treatment recommendations for BDHD cases should be tailored to the stage and the presence or absence of intra-abdominal localization. For patients with stage IA extended fields, irradiation (inverted Y) is sufficient. However, combined modality therapy should be the treatment of choice for stage II cases, particularly in the presence of intra-abdominal disease. Patients with systematic symptoms also require combined modalities.

Bone marrow involvement at onset of Hodgkin's disease.

Bilateral trephine bone marrow biopsies of 370 patients with Hodgkin's disease first seen at the Institute of Hematology, University of Rome, between 1970 and 1981, revealed tumor involvement of the bone marrow in 18 cases. The histologic type was mixed cellularity in 7 cases, lymphocytic depletion in 4 cases, nodular sclerosis in 4 cases, and lymphocytic prevalence in 1 case. Anemia with less than 10 g/dl of hemoglobin was observed in 5 patients; white blood cells were less than 4.0 X 10(9)/liter in 2 patients; platelets were less than 12.0 X 10(9)/liter in 1 case; a pancytopenic condition was observed in only 1 case. B symptoms were present in 14 of the 18 patients. All patients who underwent laparosplenectomy presented spleen involvement, 4 also had liver involvement. All patients were treated with chemotherapy; MOPP regimen was employed in 11 cases, ABVD in 5 patients, and PROVECIP in 1 case. Of the 13 patients evaluable for therapeutic response, 11 achieved complete remission, with a median actuarial relapse-free survival of 15 months. The actuarial survival curve showed that 50% of all patients are projected alive at 47 months with a follow-up ranging from 1 to 109 months.

Secondary acute non lymphoid leukemia in patients treated for non Hodgkin's lymphoma: no risk of therapy-related ANLL after PROVECIP schedule.

The present study was undertaken to evaluate the frequency, characteristics and actuarial risk of secondary acute non lymphoid leukemia (s-ANLL) in 141 patients treated for non Hodgkin's lymphoma with different modalities. One hundred and twenty-four patients received chemotherapy according to PROVECIP protocol. Of these, 15 also received as induction treatment a local nodal irradiation and 33 an extended field radiotherapy. Seventeen out of 141 were treated by total body irradiation. Of these, 15 relapsed and received salvage chemotherapy. Sixteen of the 124 patients treated with PROVECIP also underwent different chemotherapeutic programs as salvage treatment. Of the entire population studied, 2 patients developed an s-ANLL, 45 and 63 months after diagnosis of NHL. The type of treatment significantly affected the occurrence of s-ANLL, since both leukemias occurred in patients treated with total body irradiation, given alone or followed by chemotherapy. The actuarial risk at 8 years was 5.24% in the whole group, whereas it greatly increased in the group of patients treated with total body irradiation (24%). Conversely, no risk was found in the group treated with PROVECIP, alone, with additional chemotherapy, or with associated local or extended field radiotherapy.

Peripheral T cell lymphoma in adults: morphological and phenotypical study of four cases.

In the present study we investigated the lymph node morphology and distribution of cell surface phenotypes in four cases of adult peripheral T cell lymphoma. Histologically, the tumors were classified as T zone lymphoma, T cell lymphoma with large multilobated nuclei and T cell immunoblastic sarcoma. In the T zone lymphoma the neoplastic lymphocytes were E+ (90%) and exhibited intensive focal staining for acid phosphatase (93%) and acid esterase (92%); the phenotype distribution revealed low expression of the T-3 antigen (49%), selective expression of the T-4 antigen (72%) and poor expression of T-6 (10%) and T-10 antigens (22%). Some of these features are present in normal and in neoplastic immature T cells. In the remaining three cases the majority of lymph node cells were E+ (59-75%), T-3+ (67-80%) and T-8+ (43-55%). A distinctive feature of the T cell immunoblastic sarcoma was the presence of high percentages of DR+ cells (62%; 63%). Thus our results indicate that the morphological heterogeneity of peripheral T cell lymphoma is also paralleled by a variety of surface phenotypes and that phenotype studies may provide a useful contribution to identification and accurate classification of peripheral T cell neoplasms.

Second malignancy risk associated with treatment of Hodgkin's lymphoma: meta-analysis of the randomised trials.

BACKGROUND: Despite several investigations, second malignancy risks (SMR) following radiotherapy alone (RT), chemotherapy alone (CT) and combined chemoradiotherapy (CRT) for Hodgkin's lymphoma (HL) remain controversial. PATIENTS AND METHODS: We sought individual patient data from randomised trials comparing RT versus CRT, CT versus CRT, RT versus CT or involved-field (IF) versus extended-field (EF) RT for untreated HL. Overall SMR (including effects of salvage treatment) were compared using Peto's method. RESULTS: Data for between 53% and 69% of patients were obtained for the four comparisons. (i) RT versus CRT (15 trials, 3343 patients): SMR were lower with CRT than with RT as initial treatment (odds ratio (OR) = 0.78, 95% confidence interval (CI) = 0.62-0.98 and P = 0.03). (ii) CT versus CRT (16 trials, 2861 patients): SMR were marginally higher with CRT than with CT as initial treatment (OR = 1.38, CI 1.00-1.89 and P = 0.05). (iii) IF-RT versus EF-RT (19 trials, 3221 patients): no significant difference in SMR (P = 0.28) although more breast cancers occurred with EF-RT (P = 0.04 and OR = 3.25). CONCLUSIONS: Administration of CT in addition to RT as initial therapy for HL decreases overall SMR by reducing relapse and need for salvage therapy. Administration of RT additional to CT marginally increases overall SMR in advanced stages. Breast cancer risk (but not SMR in general) was substantially higher after EF-RT. Caution is needed in applying these findings to current therapies.

Successful pregnancies following an egg donation program in women with previously treated Hodgkin's disease.

BACKGROUND AND OBJECTIVES: In order to draw attention not only to patients affected by a neoplasia, but also to those who may have problems of sterility, we describe six women affected by Hodgkin's disease who had precocious menopause due to chemotherapy and/or radiotherapy but who were safely delivered of children. These pregnancies were achieved through oocyte donation, in vitro fertilization and intrauterine embryo transfer or oocyte intracytoplasmic insemination. DESIGN AND METHODS: During natural or iatrogenic menopause, the uterus preserves its capacity to respond to steroidal hormones and to permit implantation and development of an embryo. Our study concerns six young females with iatrogenic menopause caused by treatment of Hodgkin's disease who carried a pregnancy to term. The pregnancies were achieved by oocyte donation, in vitro fertilization and intrauterine embryo transfer or oocyte intracytoplasmic insemination. Endometrial maturation was obtained by administration of estradiol and progesterone. Steroidal therapy was administered until the 13th-14th week in relation to placental function. RESULTS: Five of the 6 females underwent Caesarean section because of a twin birth or complications during the third trimester of pregnancy (gestosis). All the delivered children are, to date, well; their median age is 4 years. INTERPRETATION AND CONCLUSIONS: This study confirms the possibility of women treated for Hodgkin's disease being able to carry a pregnancy safely to term with the help of steroidal therapy. Careful clinical and obstetric surveillance is important. Focusing attention on long-term survivors of Hodgkin's disease, we set the goal of improving the quality of life of these patients, considering their psychophysical well-being as a whole. Greater attention to the problems of safeguarding fertility in these patients would be advisable, also in the light of legislative regulation of medical care techniques in various countries.

Risk of infertility in patients with Hodgkin's disease treated with ABVD vs MOPP vs ABVD/MOPP.

The gonadal function of 38 patients with Hodgkin's disease (HD) treated with MOPP chemotherapy (12 patients), ABVD (9 patients) and alternating MOPP/ABVD (17 patients) has been retrospectively investigated with semen analysis. Median age of patients was 25 years (range 16-41 years). Azoospermia was found in all patients from the MOPP group (100%), in 3 of the ABVD group (33%) and in 13 of the MOPP/ABVD group (76%). After temporary oligospermia full recovery of spermatogenesis was observed in 67% of patients treated with ABVD, versus 25% of MOPP-treated patients following a prolonged period of azoospermia and oligospermia. Patients receiving MOPP/ABVD scheme had complete recovery of testicular function after oligospermia in 24% of cases. These results confirm the higher gonadal toxicity of the MOPP regimen as compared to others such as ABVD without alkylating agents.

Third-line chemotherapy with CAVP (CCNU, melphalan, etoposide and prednisone) in refractory Hodgkin's disease.

Thirty-one patients affected by recurrent Hodgkin's disease have been treated with an oral combination chemotherapy including lomustine (CCNU 90 mg/sqm, on day 1), melphalan (Alkeran, 7.5 mg/sqm on days 1-5), etoposide (VP-16, 100 mg/sqm on days 6-10) and prednisone (40 mg/sqm on days 1-10). MOPP and ABVD regimens administered sequentially or in alternating fashion had been employed as first choice treatment. The majority of patients had extranodal (80%) and a progressive disease resistant to previous chemotherapy (80%). Complete and partial remission were induced in 8 (26%) and 5 patients (16%), respectively, with an overall response rate of 42%. Median duration of complete remission was 10 months. Patients who did not respond to previous chemotherapies had a significantly lower complete response rate (16%). Myelosuppression was the most frequent complication, with one patient dying of a thrombocytopenic hemorrhage. The oral administration of drugs allowed good patients', compliance with treatment. CAVP is an effective regimen in the management of patients with refractory Hodgkin's disease and the results obtained are comparable with other third-line chemotherapies.
