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.

VEPEMB in elderly Hodgkin's lymphoma patients. Results from an Intergruppo Italiano Linfomi (IIL) study.

BACKGROUND: In advanced age the prognosis of Hodgkin's lymphoma (HL) is poor, but, as a consequence of the low incidence of HL in the elderly, prospective studies are lacking and the best treatment strategy is difficult to define. PATIENTS AND METHODS: One-hundred and five HL patients over 65 years of age were treated homogeneously with an original reduced-intensity regimen designed for HL in the elderly containing vinblastine, cyclophosphamide, procarbazine, etoposide, mitoxantrone and bleomycin (VEPEMB). Forty-eight early stage (IA-IIA) patients received three courses of VEPEMB followed by involved field irradiation. Fifty-seven advanced stage (IIB-IV) patients received six courses followed by radiotherapy limited to the areas of bulky disease. RESULTS: Mean age was 71 years (range 66-83). Co-morbidities were present in 39 patients (37%). A treatment plan modification for poor tolerance or toxicity was needed in 18 patients. Results were satisfactory, even if they were better in early rather than in advanced stage disease: complete response rate 98% versus 58% (P <0.01); 5-year failure-free survival 79% versus 34% (P <0.01). The results were affected by advanced stage, systemic symptoms and co-morbidity but they were not influenced by age itself. CONCLUSIONS: VEPEMB is an effective and low toxic regimen for HL in the elderly. Co-morbidity is a prognostic factor more important than age itself.

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.

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 of the nasopharynx: diagnostic and therapeutic approach with a review of the literature.

The lymphoid tissues of Waldeyer's ring, including the nasopharynx, are rarely involved in Hodgkin's disease (HD). Between March 1977 and July 2001, about 2150 patients affected by HD were observed in our institute; 7 of them (0.32%), all male patients, had HD of the nasopharynx. They had no symptoms and blood tests were normal. All patients were treated with chemotherapy and/or radiotherapy and achieved complete remission. At a median follow-up of 72 months, they are alive and in continuous complete remission. We conclude that Hodgkin's disease of the nasopharynx is a rare and predominantly male disease with a particularly favorable prognosis. Bone marrow biopsy could be avoided. We believe that two to four cycles of a chemotherapeutic regimen and involved field radiotherapy at an intermediate-high dosage (25-30 Gy) could be the first line treatment for these patients.

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.

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.

Conventional salvage chemotherapy vs. high-dose therapy with autografting for recurrent or refractory Hodgkin's disease patients.

Despite progress that has been made in curing Hodgkin's disease (HD), patients whose first remission is brief and those resistant to first-line chemotherapy still have a poor outcome. We retrospectively reviewed data from 29 patients with HD in first relapse or refractory to first-line chemotherapy. Following failure, all patients received three cycles of ifosfomide, epirubicin, and etoposide (IEV); moreover, 11 patients received a conditioning regimen followed by autografting. Of the 18 patients treated with IEV, eight (44%) are alive; nine died of disease progression, and one died of hematologic toxicity. The 24-month overall survival (OS), relapse-free survival (RFS), and event-free survival (EFS) are 18%, 44%, and 22%, respectively. Of the 11 patients treated with IEV and autografting, ten are alive (90%) and one patient died of progressive disease. The 29-month OS, RFS, and EFS are 91%, 71%, and 56%, respectively. Our results confirm data showing that patients with relapsed or resistant HD achieve a significantly better OS and EFS if treated with high-dose therapy and autografting.

Relapse and late complications in early-stage Hodgkin's disease patients with mediastinal involvement treated with radiotherapy alone or plus one cycle of ABVD.

BACKGROUND AND OBJECTIVE: Patients affected by Hodgkin's disease (HD) in pathologic stage IA-IIA have a strong possibility of remission and long-term survival when treated with radiotherapy to extended fields. However, 20-30% of cases relapse in the five years following treatment and consequently need further therapy. This study examines the occurrence of relapse and other complications in patients with pathologic stage IIA Hodgkin's disease and mediastinal involvement treated in different ways: radiotherapy alone vs radiotherapy plus one cycle of adriamycin, bleomycin, vinblastine and dacarbazine (ABVD). DESIGN AND METHODS: Our series consisted of 73 HD patients with mediastinal involvement treated by the Department of Radiation Oncology and the Hematology Department of "La Sapienza" University of Rome from 1983 to 1989. The patients were randomized into two groups according to their initial treatment. The first group contained 37 patients treated, initially, with supradiaphragmatic radiotherapy and para-aortic irradiation (STNI); the second group was made up of 36 patients treated, initially, with supradiaphragmatic radiotherapy and para-aortic irradiation (STNI) combined with one course of adriamycin, bleomycin, vinblastine and dacarbazine (ABVD). For 28 (38%) of the patients, the follow-up period was longer than 10 years. The average follow-up period was 114 months (range 22-174 months). Overall survival and relapse-free survival were assessed using the Kaplan and Meier method, while differences were tested by the log-rank test. RESULTS: We recorded twelve cases of relapse after initial treatment. The period of time which elapsed between the end of treatment and the evidence of relapse ranged from 6 to 51 months, with an average of 22 months. Ten relapses occurred in the STNI group and two in the ABVD/STNI group. No statistically significant differences emerged between the two groups in the overall survival analysis but did in the relapse-free survival analysis (p<0.01). In the group treated with ABVD and STNI one patient developed acute non-lymphocytic leukemia and another patient treated at the age of 44 developed primary breast cancer. X-ray-related asymptomatic pulmonary fibrosis was observed in 12 patients: 10 cases in the STNI and ABVD group and 2 cases in the group treated with RT alone. The other sequelae of combined CT/RT treatment in our study were thyroid dysfunction (2 cases, hypothyroidism), whereas the sequela of RT treatment was cardiac disease (2 cases). INTERPRETATION AND CONCLUSIONS: We conclude that one cycle of ABVD and radiotherapy in early-stage HD patients with mediastinal involvement may reduce the risk of relapse. Moreover, the combination of low-toxicity CT and RT, administered preferably to limited fields, in patients who have not undergone laparotomy could be a valid alternative to current treatment for early-stage HD. However, additional data and a longer follow-up are mandatory in order to evaluate late toxicity and the potential risk of treatment.

Long-term results of 60 patients with pathologic stage I & IIA Hodgkin's disease treated with exclusive mantle radiation therapy.

Between January 1972 and December 1982 60 patients with pathological stage IA and IIA Hodgkin's disease (HD) were submitted to Mantle irradiation only. Twenty-five were in stage I (32.1%) and 35 in stage II (67.9%). All patients were submitted to staging laparotomy. Cases with large mediastinal mass were excluded from this series. Delivered doses were 44 Gy in involved areas, 40 Gy on the mediastinum and 36 Gy on uninvolved sites. Twenty-four patients in stage I (96%) and 33 in stage II (94.2%) obtained complete remission. Actuarial 10- and 20-yr overall (OS) rates were 86% and 79.1%, respectively. Event-free (EFS) and relapse-free (RFS) survival rates at 10 and 20 yr were 67.5% and 62.1%, respectively. The occurrence of disease relapse resulted in the only statistical significant prognostic factor for OS in both univariate and multivariate analysis. Distant and extranodal recurrences were significantly (P<0.01) related to a reduced OS. On multivariate analysis stage was the only determinant factor for increased RFS. Extended field RT proved to be an effective curative modality for stage I HD patients, whereas 15 out of 33 patients in stage II relapsed requiring salvage therapy. Long-term analysis of survival and treatment-related morbidity rates will improve our knowledge and assist the physicians to choose the therapeutic option to offer to HD patients.

Hodgkin's disease during pregnancy: diagnostic and therapeutic management.

OBJECTIVES: To evaluate the possibility that women affected by Hodgkin's disease (HD) during their second or third trimester of pregnancy can safely carry their pregnancy to term. METHODS: From 1986 to 1997, 6 women came to our Center during the second trimester of pregnancy and were diagnosed as having HD. Three of these 6 patients were treated with chemotherapy before delivery and 3 of them were kept under observation and started treatment after delivery. RESULTS: All 6 women gave birth to a healthy female. CONCLUSIONS: The pregnancy does not worsen the course of the illness and does not compromise long-term clinical remission and recovery.

The risk of acute leukemia in patients treated for Hodgkin's disease is significantly higher aft [see bined modality programs than after chemotherapy alone and is correlated with the extent of radiotherapy and type and duration of chemotherapy: a case-control study.

BACKGROUND AND OBJECTIVE: Patients treated for Hodgkin's disease have an increased risk of developing subsequent acute leukemia. This co-operative study was conducted to assess the relative risk associated with several candidate factors including age, splenectomy, combined modality therapy and cumulative drug dose including alkylating agents and nitrosurea derivatives. DESIGN AND METHODS: This study evaluated the risk of acute leukemia according to pretreatment variables and therapy modalities among 1659 patients treated for Hodgkin's disease and followed for a median time of 10 years. Both case-control and actuarial risk studies were performed. Median age was 34 years (range: 12-83); 53% of patients were splenectomized. As to the overall therapy, 348 patients (21%) were given radiotherapy (RT) alone, 375 (23%) chemotherapy (CT) alone (including MOPP, MOPP + ABVD or MOPP + ABVD + lomustine); 936 (56%) received both CT and RT, either as primary or salvage treatment. RESULTS: The overall 15-year actuarial risk of leukemia was 4.2%; the hazard function curve showed two peaks of risk at the 3th and the 8th year from the initiation of therapy and no leukemia beyond the 12th year of follow-up. Risk of leukemia was 0.3% after RT alone, 2.8% after CT alone (2.2% after MOPP; 4.4% after MOPP + ABVD + lomustine), and 5.4% in patients given combined modality therapy (10.2% for RT + MOPP; 15.6% for RT + MOPP + lomustine). No leukemia occurred after ABVD alone and the risk was low (0.6%) when neither mechlorethamine nor lomustine were utilized. Patients who had received extended radiotherapy including abdomen and pelvis in addition to MOPP showed a significantly higher risk of leukemia compared to those given limited RT + MOPP (P = 0.01). Case-control analysis indicated advanced stage, type and duration (> 8 months) of CT and extension of RT as significant risk factors for leukemia. Compared to RT alone, the odds ratio was 5.9 after MOPP + extended RT, and 8 when a lomustine-containing regimen was used, as well. Neither age nor splenectomy were independent risk factors for leukemia; splenectomy was influential only when patients had been given MOPP chemotherapy, as well. INTERPRETATIONS AND CONCLUSIONS: Both case-control and actuarial analyses indicated that: a) combined modality therapy with MOPP and extensive RT (including abdomen and pelvis), and the use of lomustine added to the leukemogenic risk of MOPP alone; b) programs without mechlorethamine, procarbazine and lomustine were almost devoid of leukemogenic risk.

Avascular osteonecrosis in patients treated for Hodgkin's disease.

The aim of this study is to assess the risk of avascular osteonecrosis (AVN) of the femoral head in patients treated for Hodgkin's disease (HD), in relation to the type of treatment they have received. For this purpose, a cohort of 1391 patients treated for HD at University of Rome between 1972 and 1996 was divided into 2 groups according to their initial treatment. The first group contained 784 patients treated, at the onset of HD, either with chemotherapy (CT) containing steroids, combined in some cases with subdiaphragmatic radiotherapy (RT), or with subdiaphragmatic RT combined with CT without steroids. The second group was made up of 607 patients who had received, initially, supradiaphragmatic RT alone or supradiaphragmatic RT combined with CT without steroids. For the purpose of this study, only the 784 patients belonging to the first group were observed for the appearance of AVN, which occurred in 9 cases. The period of time which elapsed between the end of treatment and the radiological evidence of AVN ranged from 23 to 97 months, with an average of 35 months. Because the number of cases of AVN was so small, the pathogenesis of this complication could not be identified.

The risk of non-Hodgkin's lymphoma after Hodgkin's disease, with special reference to splenic treatment.

BACKGROUND AND OBJECTIVE: One of the consequences of the enormous improvement in survival rates of patients treated for Hodgkin's disease (HD) is the emergence in the long term of treatment-related complications, particularly secondary cancers. This study was undertaken to observe the occurrence of non-Hodgkin's lymphoma (NHL) in patients treated for HD and to identify the etiological role of various risk factors, especially spleen irradiation, in the pathogenesis of this illness. DESIGN AND METHODS: From 1972 to 1996, the Department of Radiation Oncology and the Hematology Section of "La Sapienza" University of Rome observed and analyzed the occurrence of NHL in 1,391 patients treated for HD. The average follow-up period was 84 months. For a more accurate calculation of the risk of the occurrence of NHL, the patients were first divided into 3 groups according to their initial treatment and also according to the total treatment they had received. Then, in order to establish the possible connection between NHL and splenic treatment the patients were also divided into 3 subgroups according to whether they had undergone splenectomy, splenic irradiation or neither of these. Two different methods of statistical analysis were used: (a) the cumulative risk (confidence interval) was evaluated in relation to treatment (initial and at the time of salvage) and (b) the Cox model was applied to identify the variables which play a role in the appearance of NHL. The cumulative risk of developing NHL was assessed using the Kaplan and Meier method. A multivariate analysis was performed using the Cox Proportional Hazard Model. RESULTS: A total of 20 cases of NHL were observed, appearing between 17 and 206 months after initial treatment. The cumulative risk was 0.8%, 1.8%, 2.6% and 3.5% at 5, 10, 15 and 20 years respectively. According to the multivariate analysis, significant risk factors were splenic irradiation and age (> 40 years). Splenic irradiation (vs no splenectomy/no splenic irradiation) showed a relative risk of 5.69, p = 0.0280, while age over 40 showed a relative risk of 3.05, p = 0.0152. INTERPRETATION AND CONCLUSIONS: From the results of this study, if appears that there is a possibility that splenic irradiation and age over 40 increase the risk of NHL in HD patients. Further studies are needed to investigate in greater depth the role of spleen irradiation in the occurrence of this illness.

Combined modality therapy in advanced Hodgkin's disease: a report on 218 patients with a median follow-up of eight years.

BACKGROUND AND OBJECTIVE: This study was designed to evaluate the efficacy and toxicity of monthly alternating ABVD/MOPP compared to ABVD/OPP regimens in patients with advanced stage Hodgkin's disease (HD), as well as in early stage patients with systemic symptoms and/or bulky disease. DESIGN AND METHODS: 218 patients with previously untreated HD entered this study: 106 patients in arm A (ABVD/MOPP) and 112 in arm B (ABVD/OPP). Patients received eight courses of one of the two regimens after stratification according to the stage. Patients in complete remission (CR) received 20 Gy to the involved field and 40 Gy to the spleen. The actuarial survival curves were performed according to Kaplan and Meier. RESULTS: No statistically significant differences were observed between the two arms in terms of CR rate and toxicity. However, analysis of total relapses revealed that patients treated with ABVD/OPP had a significantly higher likelihood of achieving a second CR compared to patients who entered the ABVD/MOPP arm. INTERPRETATION AND CONCLUSIONS: Both schemes of chemotherapy followed by radiotherapy produce high percentages of CR, low risk of relapse and an acceptable toxicity.

Acute nonlymphocytic leukemia: onset after treatment for Hodgkin's disease.

This study was undertaken to examine the influence of various factors on the occurrence of acute nonlymphocytic leukemia (ANLL) in a group of longterm survivors of Hodgkin's disease (HD). From 1972 to 1992, 1045 patients with HD were assessed and treated at the Department of Radiation Oncology, the Institute of Radiology, and the Department of Human Biopathology, Hematology Section, University of Rome "La Sapienza". The average follow-up was 72 months. For a more accurate calculation of the risk of ANLL occurrence, the patients were first divided into three subgroups according to initial treatment and then according to the total treatment they had received. Moreover, to establish the probable connection between leukemia and splenic treatment the patients were also divided into three subgroups (splenectomy, splenic irradiation, and no splenectomy/no splenic irradiation). Sixteen cases of ANLL were recorded, giving an overall risk of 0.2% at 5 years and 3.4% at 20 years. In 12 patients overt leukemia was preceded by a myelodys-plastic syndrome. Five cases had evaluable chromosome analysis. Clonal chromosome abnormalities were demonstrated in two patients, whereas three patients showed an apparently normal karyotype. Bone marrow agar cultures were analyzed in two patients and were abnormal in both cases. In the radiotherapy (RT) group, the cumulative risk was 0.4% at 10 years and 3.2% at 15 and 20 years: in the chemotherapy (CT) group it was 1.2% at 10, 15, and 20 years; in the combined group it was 3.7% at 10 years and 4.9% at 15 and 20 years. In the multivariate analysis, MOPP treatment with or without RT is a statistically significant variable for ANLL occurrence (p = 0.009). This study demonstrates that splenic treatment does not lead to ANLL. Treatment with MOPP alone and with MOPP plus RT can increase the risk of ANLL.

Analysis of the risk of solid tumor following Hodgkin's disease.

BACKGROUND AND OBJECTIVE: This study examines the occurrence of solid tumor (ST) in relation to the different types of therapy (radiotherapy, chemotherapy and radiochemotherapy; splenectomy or splenic irradiation vs no splenectomy-no splenic irradiation) received by patients treated for Hodgkin's disease (HD). METHODS: The study included 1,045 HD patients treated at the Department of Radiation Oncology, the Institute of Radiology and the Department of Human Biopathology, Hematology Section, University of Rome, "La Sapienza", from 1972 to 1992. For 23% of the patients the follow-up period was longer than 10 years. The average follow-up period was 72 months. For a more accurate calculation of the risk of ST occurrence, the patients were first divided into 3 subgroups according to initial treatment and then according to the total treatment they had received. Moreover, to establish a probable connection between solid tumor and splenic treatment the patients were also divided into 3 subgroups (splenectomy, splenic irradiation and no splenectomy/no splenic irradiation). RESULTS: We recorded twenty-four cases of ST after initial treatment. Secondary solid tumor showed a cumulative risk of 0.2% and 13.4% at 5 and 20 years, respectively. After initial treatment with radiotherapy (RT) alone, the cumulative risk was 1.7% and 5.2% at 10 and 20 years, respectively; in the chemotherapy (CT) group, it was 2.4% and 18.1%; in the CT(+)RT group, it was 1.7% and 9%. No statistically significant differences were observed among the different types of treatment (splenectomy, splenic irradiation or no splenectomy/no splenic irradiation) as regards the occurrence of ST. According to multivariate analysis, the most important factor in the risk of ST was age (> 40). Relative risk was 5.2, p = 0.0001. INTERPRETATION AND CONCLUSIONS: We conclude that an age of over 40 at diagnosis and treatment with CT alone greatly increase the risk of solid tumor occurrence.

Meningeal localization in a patient with Hodgkin's disease. Description of a case and review of the literature.

We report the case of a 21-year-old man in whom intracranial localization was discovered during initial staging at the onset of Hodgkin's disease (HD). The patient was treated by surgical excision, irradiation and chemotherapy and 50 months after completion of therapy is in remission with no evidence of HD. A brief review of the literature regarding 48 patients with intracranial Hodgkin's disease is presented.

Long-term results of treatment of childhood and adolescent Hodgkin's disease in 73 patients: the experience of the Departments of Radiology and Hematology of the University of Rome "La Sapienza".

PURPOSE: Various experiences show no substantial differences between children and adults in the treatment of Hodgkin's disease. In consideration of some peculiar characteristics of these cases which might influence the therapeutical choice, particularly regarding long-term survival and therapeutical complications, we report the results of a series of 73 children and adolescents with Hodgkin's disease treated at the University of Rome "La Sapienza". METHODS: Between 1976 and 1983, 73 untreated pediatric cases of stage I-IV Hodgkin's disease were treated with radiotherapy, alone or associated with chemotherapy, using high doses and extended fields. RESULTS: Fifty-six patients (77%) were in continuous complete remission in April 1995 and seventeen (23%) had died. CONCLUSIONS: The authors confirm the excellent results in the treatment of pediatric Hodgkin's disease, both in terms of overall and relapse free survival, in spite of a high incidence of complications caused by the aggressive treatment used in this series. Therefore the majority of authors suggest combined alternating low-dose radiation administered with small portals and short-term chemotherapy. These procedures provide optimal results together with a significant reduction of complications. Consequently, it is very important to evaluate all patient characteristics accurately in order to tailor optimal treatment and select cases with risk factors which might be undertreated and therefore undergo a higher risk of recurrence.

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.
