Second malignancies after autologous haematopoietic stem cell transplantation following modified BEAM conditioning regimen in patients with Hodgkin lymphoma – characteristics and risk factors analysis

Aim of the studyThe aim of the study was to determine the incidence of second malignancies among patients with Hodgkin lymphoma (HL) treated with autologous haematopoietic stem cell transplantation (ASCT) following a modified BEAM (BCNU, etoposide, cytarabine, melphalan, dexamethasone) regimen between 1992 and 2012 at our department. We also intended to define the risk factors for the occurrence of second neoplasm after ASCT.Material and methodsThe long-term outcomes after transplant were evaluated in 170 patients, median age 31 years (range 17–61), who received a median of two pre-transplant chemotherapy lines (range 1–5).ResultsMOPP (mechlorethamine, vincristine, procarbazine, prednisone) or MOPP-type regimens were given to 12% of patients prior to ASCT. The median follow-up of the survivors was 73 (12–242) months. The 7-year overall survival and progression-free survival were 75% and 64%, respectively. Second malignancies occurred in 7 of the 170 patients, including 5 haematological malignancies, and 2 solid tumors. They developed at a median of 8 years (range 0.4–13.5) from ASCT. The 10-year and 15-year cumulative incidence of developing a second malignancy were 7% and 13%, respectively. In multivariate analysis, age ≥ 40 years at transplant (HR = 8.8; p = 0.008) and pre-transplant MOPP-type chemotherapy (HR = 5.6; p = 0.030) were the only factors significant for developing a second malignancy.ConclusionsOur results indicate that age of patient and the type of pre-transplant chemotherapy contribute to the risk of the development of a second neoplasm after ASCT in patients with HL. We believe that better characterization of second malignancies and associated risk factors may be useful for clinicians who care for these patients.

Reduced intensity treatment in early-stage Hodgkin’s lymphoma

Reduced intensity treatment in early-stage Hodgkin’s lymphoma Prathima Prodduturi, James O ArmitageUniversity of Nebraska Medical Center, Omaha, NE, USAAbstract: Early-stage Hodgkin’s lymphoma which includes patients with Ann Arbor stages I or II, accounts for more than 50% of all cases of the illness and is curable in a high proportion of patients. Long-term follow-up has shown that the mortality in favorable-risk patients with early-stage Hodgkin’s lymphoma is exceeded by other causes including secondary malignancies and cardiac disease. Over the decades the treatment paradigm in Hodgkin’s lymphoma has evolved from extended field radiotherapy to combined modality therapy using involved field radiotherapy to using chemotherapy alone. The data on long-term complications from using low dose and limited field radiation therapy is still awaited since we know that most of the secondary malignancies occur late (ie, more than 10 years after the treatment). By changing the chemotherapy regimens from mechlorethamine, vincristine, procarbazine, prednisone (MOPP) to doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) the incidence of infertility and leukemia has been reduced. Since the late toxicity was high with radiotherapy, recent studies have focused on using chemotherapy alone. The results of interim positron emission tomography (PET) scans after two cycles of chemotherapy are being tested to see whether minimizing therapy in rapidly-responding patients will still maintain excellent cure rates. Here, we have reviewed some of the important clinical trials in early-stage Hodgkin’s lymphoma and focus on some of the recent trials emphasizing reduced intensity treatment in early-stage Hodgkin's lymphoma.Keywords: Hodgkin’s lymphoma, treatment, early-stage, intensity, mortality

Long-Term Follow-Up Analysis of HD9601 Trial Comparing ABVD Versus Stanford V Versus MOPP/EBV/CAD in Patients With Newly Diagnosed Advanced-Stage Hodgkin's Lymphoma: A Study From the Intergruppo Italiano Linfomi

The Intergruppo Italiano Linfomi HD9601 trial compared doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) versus doxorubicin, vinblastine, mechloretamine, vincristine, bleomycin, etoposide, and prednisone (Stanford V [StV]) versus the combination of mechlorethamine, vincristine, procarbazine, prednisone (MOPP) with epidoxorubicin, bleomycin, vinblastine (EBV), lomustine, doxorubicin, and vindesine (CAD) (MOPP/EBV/CAD [MEC]) for the initial treatment of advanced-stage Hodgkin's lymphoma to select which regimen would best support a reduced radiotherapy program (limited to two or fewer sites of either previous bulky or partially remitting disease). Superiority of ABVD and MEC to StV was demonstrated. We report analysis of long-term outcome and toxicity. Patients with stage IIB, III, or IV were randomly assigned among six cycles of ABVD, three cycles of StV, and six cycles of MEC; radiotherapy was administered in 76, 71, and 50 patients in the three arms, respectively. Currently, the median follow-up is 86 months; in the prolonged observation period, eight additional failures, including two relapses, both in the StV arm, and six additional deaths in complete response were recorded. The 10-year overall survival rates were 87%, 80%, and 78% for ABVD, MEC, and StV, respectively (P = .4). The 10-year failure-free survival was 75%, 74%, and 49% in the ABVD, MEC, and StV arms, respectively (P < .001). The 10-year disease-free survival of patients treated or not with radiotherapy (RT) showed no difference for ABVD or MEC (85% v 80% and 93% v 68%), and a statistically significant difference for StV (76% v 33%; P = .004). No significant long-term toxicity was recorded. The long-term analysis confirmed ABVD and MEC superiority to StV. The use of RT after StV was established as mandatory. ABVD is still to be considered as the standard treatment with a good balance between efficacy and toxicity.

One size for all in Hodgkin lymphoma?

Over the past decades, cure rates in Hodgkin lymphoma (HL) have steadily improved. This was most obvious in patients with advanced disease after the introduction of multi-agent chemotherapy protocols such as MOPP (mechlorethamine, vincristine, procarbazine, prednisone) and ABVD (adriamycin, bleomycin, vinblastine, dacarbazine). More recently, the more intensive BEACOPP(escalated) (bleomycin, etoposide, adriamycin, cyclophosphamide, vincristine, procarbazine, prednisone) was shown to be significantly superior to previous standard approaches in advanced adult HL. In this issue of Blood, Kelly and colleagues now report that BEACOPP(escalated) is also feasible and highly effective in high-risk pediatric and adolescent HL patients.

Treatment-related risk factors for premature menopause following Hodgkin lymphoma

We conducted a cohort-study among 518 female 5-year Hodgkin lymphoma (HL) survivors, aged 14 to 40 years (median: 25 years) at treatment (1965-1995). Multivariable Cox regression was used to quantify treatment effects on risk of premature menopause, defined as cessation of menses before age 40 years. After a median follow up of 9.4 years, 97 women had reached menopause before age 40 years. Chemotherapy was associated with a 12.3-fold increased risk of premature menopause compared with radiotherapy alone. Treatment with MOPP (mechlorethamine, vincristine, procarbazine, prednisone)/ABV (doxorubicine, bleomycine, vinblastine) significantly increased the risk of premature menopause (hazard ratio [HR]: 2.9), although to a lesser extent than MOPP treatment (HR: 5.7). Alkylating agents, especially procarbazine (HR: 8.1) and cyclophosphamide (HR: 3.5), showed the strongest associations. Ten years after treatment, the actuarial risk of premature menopause was 64% after high cumulative doses (> 8.4 g/m(2)) and 15% after low doses (<or= 4.2 g/m(2)) of procarbazine. The cumulative risk of menopause at age 40 years did not differ much according to age, but time to premature menopause was much longer in women treated at early ages. As long as alkylating agents will be used for curing HL, premature menopause will remain a frequent adverse treatment effect, with various clinical implications.

Comparison of 3 Protocols for Treatment after Induction of Remission in Dogs with Lymphoma

Background: The optimal treatment after inducing complete remission (CR) in dogs with lymphoma has not been established. Hypothesis: After inducing CR with L‐asparaginase, vincristine, cyclophosphamide, doxorubicin, prednisone (L‐CHOP); consolidation with either half‐body radiation therapy (HBRT); or lomustine (CCNU) and mechlorethamine, vincristine, procarbazine, prednisone (MOPP) would improve first remission duration compared with continuing a CHOP‐based protocol for an additional 4 months. Animals: Dogs with stage III‐V lymphoma. Methods: Prospective clinical trial in which dogs initially were treated with an 8‐week induction protocol that consisted of L‐CHOP. Dogs in CR after induction were then allocated to 1 of 2 consolidation arms. A chemotherapy consolidation arm consisted of 2 treatments with CCNU and 1 cycle of MOPP. A HBRT arm consisted of 2 sequential 8.0‐Gy fractions to the cranial and caudal half‐body separated by 30 days. Vincristine was given between fractions. Results of the consolidation arms also were compared with a historical group treated with the same 8‐week induction protocol followed by CHOP therapy until week 24. Results: Overall, 67% of the dogs were in CR after 8 weeks of induction chemotherapy and were compared. Fifty‐two dogs were in the historical arm, 23 in the CCNU/MOPP arm, and 27 in the HBRT arm. No difference in first remission duration was found among groups. Median first remission duration for the historical, CCNU/MOPP, and HBRT arms were 307, 274, and 209 days, respectively (P= .28). Overall second CR rate was 82% and was not different among groups (all P &gt; .58). Overall remission duration (P= .28) and survival time (P= .48) were not different among groups. Conclusions and Clinical Importance: Consolidation with either CCNU/MOPP or HBRT showed no advantage over a standard CHOP‐based protocol.

APE chemotherapy for children with relapsed Hodgkin disease: A Pediatric Oncology Group trial

MOPP (mechlorethamine, vincristine, procarbazine, prednisone) and ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) are effective therapies for Hodgkin disease (HD) that may cause long-term toxicities in children. APE (cytosine arabinoside, cisplatin, etoposide) is a non-cross-resistant regimen with limited toxicities. We evaluated this regimen for patients with recurrent or refractory disease. Patients with recurrent Hodgkin disease who were <or=21 years of age and had previously received standard alkylating agent and doxorubicin-based therapy, were treated with APE chemotherapy (cytosine arabinoside 750 mg/m(2), cisplatin 15 mg/m(2), etoposide 20 mg/m(2)) every 12 hr, administered three or four times per cycle. Response, Event-free survival (EFS), and overall survival (OS) were assessed. Thirty-one patients in first (n = 25) or second (n = 6) relapse of Hodgkin disease were eligible and evaluable. APE chemotherapy was well-tolerated, with the major toxicity consisting of short duration, grade 3/4 hematopoietic toxicity. The CR/PR response rate was 68% (42% CR, 26% PR). Allowing subsequent stem cell transplantation in some patients, 4-year EFS and OS were 27% +/- 8% and 49% +/- 9%, with 8-year EFS and OS of 23% +/- 9% and 34% +/- 10%. APE is an efficacious regimen with minimal toxicity. Novel regimens are necessary to: (1) re-induce remission, (2) treat newly diagnosed patients, and (3) augment therapy in patients with slow response to standard regimens. This regimen had minimal toxicity and an excellent response rate that facilitated long term survival, often in conjunction with transplantation. The Children's Oncology Group is using a similar regimen to augment therapy for slow responders on a current Hodgkin disease trial.

Late Non-Neoplastic Events in Patients with Aggressive Non-Hodgkin's Lymphoma in Four Randomized European Organisation for Research and Treatment of Cancer Trials

BackgroundA significant proportion of patients with aggressive non-Hodgkin's lymphoma (NHL) become long-term survivors. A European Organisation for Research and Treatment of Cancer database of patients with aggressive NHL, consistently treated with doxorubicin-based chemotherapy since 1980, afforded the possibility to explore late complications in this patient group. Patients and MethodsOf 951 randomized patients, complete data on late complications could be collected in 757 patients who were alive ≥ 2 years after the start of therapy and were seen at yearly follow-ups (median follow-up, 9.4 years; range, 2.1-20.4 years). We computed cumulative incidences of late events in a competing risk model by Gray (death being the competing event) to avoid bias caused by the high percentage of NHLrelated deaths. Risk factors were estimated in a Cox proportional-hazards model and also evaluated with the Gray test. ResultsLate non-neoplastic events were found in 46% of the 757 patients. At 15 years, the cumulative incidences of cardiac disease and infertility were 20% and 29%, respectively. Renal insufficiency (11%), acquired hypertension (8%), and disabling neuropathy (13%) were also frequent. Salvage treatment was a risk factor in most cases. Smoking, age > 50 years during treatment, and preexistent hypertension were the main risk factors for cardiovascular disease. In-field radiation therapy (RT) was related to hypothyroidism, lung fibrosis, hypertension, gastrointestinal toxicity, and renal insufficiency but not to cardiovascular events. Autologous stem cell transplantation and cisplatin- and MOPP (mechlorethamine/vincristine/procarbazine/prednisone)–containing therapies were associated with infertility and renal insufficiency. ConclusionAltogether, almost half the patients with aggressive NHL experienced events addressed as late non-neoplastic complications. Salvage therapy, smoking, age > 50 years, and in-field RT are important risk factors.

Trials in Advanced Hodgkin's Disease: More than 30 Years Experience of the British National Lymphoma Investigation

Hodgkin's disease demonstrates an exquisite sensitivity to chemotherapy and radiation therapy. This necessitates investigation of modes of delivering these modalities in the best possible fashion to improve outcomes. The British National Lymphoma Investigation (BNLI) has conducted randomized trials in advanced Hodgkin's disease for > 30 years. The results of BNLI studies have demonstrated that MOPP (mechlorethamine/vincristine/procarbazine/prednisone) chemotherapy is superior to MOP (mechlorethamine/vincristine/procarbazine) chemotherapy; that there are no significant differences between MOPP and B-MOPP (MOPP plus bleomycin); that there is no significant benefit from maintenance therapy with lomustine/vinblastine/bleomycin; that LOPP (chlorambucil/vincristine/procarbazine/prednisone) is as effective as MOPP and has less acute toxicity; that alternating therapy with LOPP and EVAP (etoposide/vinblastine/doxorubicin/prednisolone) is superior to EVAP alone or hybrid LOPP and EVA (etoposide/vinblastine/doxorubicin); that alternating therapy with ChlVPP (a substitute for MOPP) and prednisolone/doxorubicin/bleomycin/vincristine/etoposide regimens is superior to the latter regimen alone; that the Stanford V regimen (doxorubicin/vinblastine/mechlorethamine/vincristine/bleomycin/etoposide/prednisone) combined with disciplined radiation therapy is safe and effective; that hybrid therapy with ChlVPP and EVA and alternating therapy with ChlVPP and prednisolone/ doxorubicin/bleomycin/vincristine/etoposide are as effective as ABVD (doxorubicin/bleomycin/vinblastine/dacarbazine) alone; and that there is no additional benefit from total nodal irradiation or combined-modality therapy compared with MOPP; and that treatment with high-dose BEAM (carmustine/etoposide/cytarabine/melphalan) and autologous bone marrow transplantation is superior to mini- BEAM (lower-dose BEAM not requiring bone marrow rescue) for poor-risk relapsed and refractory disease.

Advanced stage and unfavorable Hodgkin's disease in the Chinese-a 20-year experience.

We retrospectively analyzed 57 patients with advanced stage (stage III/IV) or unfavorable (presence of B symptoms or bulky disease) Hodgkin's disease from January 1977 to December 1997. There were 29 male and 28 female patients. The median age was 27 years old (range, 13-59). Lactate dehydrogenase levels ranged from 104 units/l to 2320 units/l (median, 433). Eighteen (31.6%), 13 (22.8%), and 26 (45.6%) patients had stage II bulky, stage III, and stage IV disease, respectively. Twenty-five (44%) patients had B symptoms. One (1.8%), 3 (5.3%), 36 (63.2%), and 17 (29.8%) had lymphocyte predominant, lymphocyte depleted, nodular sclerosis, and mixed cellularity histology, respectively. Chemotherapy regimens included mechlorethamine, vincristine, procarbazine, prednisone (MOPP) (n = 9), adriamycin, bleomycin, vinblastine, dacarbazine (ABVD) (n = 23), MOPP alternating with ABVD (n = 13), and COPP-ABV hybrid (n = 12). Complete remission was achieved in 47 (82.4%) patients. Eleven patients (23%) relapsed after the first complete remission and four (36%) attained a second complete remission with salvage chemotherapy. Projected overall survival was 69.0% at 10 years and 20 years. Disease-free survival rates were 71% at 10 years and 20 years. Of the potential prognostic factors analyzed (age, sex, stage, lactate dehydrogenase, serum albumin level, regimen, B symptoms and bulky disease) by using the Cox regression model, only a low albumin level was found to adversely affect overall survival (P = 0.003). In conclusion, despite the relative low incidence of Hodgkin's disease in Hong Kong Chinese, the treatment outcomes in patients with advanced stage or unfavorable Hodgkin's disease is comparable to Caucasian patients.

Is there an effective salvage therapy for advanced Hodgkin's disease?

The availability of increasing numbers of active agents has led to the development of a succession of regimens for use as alternative and second-line therapy following relapse from or refractoriness to MOPP (mechlorethamine/vincristine/procarbazine/prednisone) or its variants. ABVD (doxorubicin/bleomycin/vinblastine/dacarbazine) has been the most widely used and has been considered non-cross-resistant. Other programs containing the nitrosourea lomustine have been used with results similar to those with ABVD. A relatively small fraction of relapsed patients remain failure free at 5 years (about 20% to 30%) despite a 30% to 60% second-line complete response (CR) rate. The few randomized trials (Cancer and Leukemia Group B [CALGB], European Organization for Research and Treatment of Cancer) evaluable to assess the efficacy of alternating MOPP/ABVD compared with MOPP alone have shown a small but significant advantage in freedom from progression and/or survival favoring the complex regimens over MOPP. The CALGB trial (8251) included a third arm of ABVD alone. The ABVD and MOPP/ABVD arms had a higher CR rate and superior failure-free survival (FFS) than did MOPP, but have thus far shown no difference between ABVD and alternating MOPP/ABVD, suggesting that full doses of a single regimen are equivalent to the more complex multidrug regimen. The next step in the CALGB program was to attempt to improve ABVD. The substitution of etoposide, an active single agent, for dacarbazine and bleomycin in ABVD resulted in a new regimen, EVA (etoposide/vinblastine/doxorubicin). This program has already demonstrated a 66% response rate in MOPP-resistant/relapsed patients (CALGB 8751).(ABSTRACT TRUNCATED AT 250 WORDS)

Primary and salvage chemotherapy in advanced Hodgkin's disease: The Milan Cancer Institute experience

This paper reviews the most relevant therapeutic results achieved by the Milan Cancer Institute through successive randomized studies in advanced Hodgkin's disease. The experience achieved confirms the therapeutic importance of an anthracycline-containing regimen such as ABVD (doxorubicin/bleomycin/vinblastine/dacarbazine) as salvage treatment and as primary chemotherapy, either when combined with irradiation or cyclically alternated with MOPP (mechlorethamine/vincristine/procarbazine/prednisone). Anthracycline-based combinations can be further refined to decrease toxicity. The biologic aspects of drug-sensitive v drug-resistant tumor cells and the accurate definition of prognostic categories at the time of first treatment failure are also discussed.

Long-term follow-up of ProMACE-CytaBOM in non-Hodgkin's lymphomas

Initial results from studies with third-generation combination chemotherapy regimens for the treatment of aggressive non-Hodgkin's lymphomas (NHL) demonstrated complete remission (CR) rates higher than those reported with first-generation regimens. Long-term follow-up of these studies is required to know if the increased number of CRs translates into an increased number of long-term disease-free survivors. In this report, results obtained with one of the third-generation regimens, ProMACE (prednisone/methotrexate/doxorubicin/cyclophosphamide/etoposide)-Cyta BOM (cytarabine/bleomycin/vincristine/methotrexate) are described. From 1981 to 1988, 193 patients with stage II, III, or IV aggressive NHL treated at the National Cancer Institute were randomly assigned to receive either ProMACE (day 1)-CytaBOM (day 8) or ProMACE (day 1)-MOPP (mechlorethamine/vincristine/procarbazine/prednisone) (day 8). With a median follow-up of 5 years, the CR rate was 86% for ProMACE-CytaBOM v 74% for ProMACE-MOPP (P = 0.048). A plateau in the disease-free survival curve is seen at 69% for ProMACE-CytaBOM v 54% for ProMACE-MOPP (P = 0.082). A plateau is also seen in the overall survival curves at 69% for ProMACE-CytaBOM v 53% for ProMACE-MOPP (P = 0.046). The Southwest Oncology Group also conducted a phase II study of ProMACE-CytaBOM in 78 patients with stages II to IV intermediate- or high-grade NHL to determine the CR rate and long-term disease-free survival of this regimen in a national cooperative group setting. The CR rate was 65%. With a median follow-up of 38 months, disease-free survival is 50% at 3 years and overall survival is 57% at the same time point.(ABSTRACT TRUNCATED AT 250 WORDS)

Can MOPP be replaced in the treatment of advanced Hodgkin's disease?

MOPP (mechlorethamine, vincristine, procarbazine, prednisone) was the first successful regimen for the treatment of Hodgkin's disease. It has the longest period of follow-up and is best studied as to its benefits and acute and long-term side effects. The acute toxicity of the side effects, including nausea and/or vomiting, hair loss, and myelosuppression, may have been reason to modify doses of nitrogen mustard, an agent whose dose intensity may be critical in achieving long-term benefits. The substitution of chlorambucil and vinblastine in the ChlVPP (chlorambucil, vinblastine, procarbazine, prednisone) program has relieved all of these acute toxicities, except myelosuppression. The long-term toxicity of sterility, especially in males, and myelodysplasia is most likely due to alkylating-agent toxicity and would not be influenced by the various MOPP variants, such as MVPP (mechlorethamine, vinblastine, procarbazine, prednisone), ChlVPP, and COPP (chlorambucil-vincristine, procarbazine, prednisone). Doxorubicin-containing regimens, such as ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) and ABDIC (doxorubicin, bleomycin, dacarbazine, lomustine, prednisone), have been second-line treatments that have significant antitumor effect and, as such, have resulted in few, if any, long-term cures in most series. ABVD has been incorporated into alternating MOPP/ABVD schemes or in hybrids that attempt to offer all active agents, such as MOPP/ABV. The initial experience has been encouraging with high and durable complete remissions (CRs). MOPP/ABVD x 12(1) and MOPP-2/ABVD-2(2) have been compared with MOPP alone with a significant superiority for the alternating regimens. Other randomized trials have not shown any superiority for the alternating program. The Cancer and Leukemia Group B (CALGB) has compared MOPP with MOPP/ABVD given with a third arm of ABVD alone. The complete response and time-to-treatment failure rates for MOPP/ABVD and ABVD alone were superior to those for MOPP. Significant modifications of MOPP doses may explain the differences, since only 20% of patients were receiving full doses of nitrogen mustard by the sixth dose. ABVD has unique toxicity, and myelodysplasia and sterility are not seen. Pulmonary fibrosis with radiation and bleomycin is unique to ABVD, as shown in the ABVD experience at the NCl (Milan). Can ABVD be improved? The demonstrated single-dose activity of etoposide in Hodgkin's disease has prompted its inclusion in second-line programs, such as EVA (etoposide, vincristine or vinblastine, doxorubicin). The second-line response rates in the St Bartholomew's (London, England) series (where vincristine was used) was 11 of 19 patients (58%);3 in the ongoing CALGB trial of EVA (vinblastine combination), the response rate is 67%.

Toward comprehensive management tailored to prognostic factors of patients with clinical stages I and II in Hodgkin's disease. The EORTC Lymphoma Group controlled clinical trials: 1964-1987

From 1964 to 1987, the EORTC Lymphoma Group conducted four consecutive controlled clinical trials on clinical stages I and II Hodgkin's disease in which 1,579 patients were entered. From the onset the main aim of these trials was to identify the subsets of patients who could be treated safely by regional radiotherapy (RT). Therefore, several prognostic indicators were prospectively registered and progressively used in the trial protocols for the delineation of the favorable and unfavorable subgroups as soon as they were recognized of high predictive value. In the H2 trial (1972 to 1976), the histologic subtype was the only variable taken into account for the therapeutic strategy and the staging laparotomy findings were found to be of prognostic value only in patients with favorable prognostic indicators. In the H5 trial (1977 to 1982), patients were subdivided into two subgroups according to six prognostic indicators. Patients with favorable features were submitted to a staging laparotomy (lap); lap negative patients were randomized between mantle field RT and mantle field plus paraaortic RT. Disease free survival (DFS) and total survival (S) were similar in the two arms. Among patients with unfavorable features, DFS and S were significantly higher in the arm treated by combination of mechlorethamine, vincristine, procarbazine, prednisone (MOPP) chemotherapy (CT) and RT than in the arm treated by total nodal irradiation. Nevertheless, in patients below the age of 40, the overall survival rates were equivalent in the two arms. In the H6 trial, the delineation of the favorable subgroup was based on (a) absence of systemic symptoms and elevated ESR, (b) no more than one or two lymph node areas involved. The aim of the study was to assess the impact on survival of a therapeutic strategy including staging laparotomy. At a 4-year follow-up, no difference in survival was evidenced. In patients with unfavorable prognostic indicators, 3 MOPP- RT-3 MOPP were compared with 3 ABVD-RT-3 ABVD. From H1 to H5 trials, the proportion of patients having received CT during the course of the disease gradually decreased; the data suggest that a further reduction in the proportion of patients aggressively treated is conceptually possible. On the basis of the prognostic factors identified, one can delineate three subsets of patients and modulate toxic cost of the initial treatment according to the characteristics of these subsets. In the most favorable subgroup, RT alone produces high survival and CT is not justified.(ABSTRACT TRUNCATED AT 400 WORDS)

The pathologic and clinical heterogeneity of lymphocyte-depleted Hodgkin's disease.

Patients with Hodgkin's disease of the lymphocyte-depleted subtype (LDHD) have been said to have a poor prognosis. However, reports of this subtype are complicated by the fact that the histologic diagnosis of LDHD is often not straightforward, and its distinction from aggressive non-Hodgkin's lymphomas (NHL) can be difficult. We have reviewed our patients with LDHD at the National Cancer Institute (NCI) in light of an additional decade of experience with neoplastic and non-neoplastic conditions mimicking Hodgkin's disease. Of 198 patients who received MOPP (mechlorethamine, vincristine, procarbazine, prednisone) treatment at the NCI for Hodgkin's disease between 1964 and 1976, 43 (22%) were originally classified as LDHD. The initial diagnostic biopsies from 39 of these patients were reviewed and revealed ten with NHL, nine with LDHD, and 13 with nodular sclerosing Hodgkin's disease of the lymphocyte-depleted subtype (NSLD). The other seven patients had Hodgkin's disease without a lymphocyte-depleted component. The NHL patients were further subclassified as diffuse, large-cell (two cases) and large-cell, immunoblastic (eight cases). The pathologic review was done without knowledge of clinical features which were examined after review in the three major subgroups. Of ten patients with NHL, only three had a complete remission (CR), and median survival was 7 months. Nine of the NHL patients presented with features that are unusual for patients with Hodgkin's disease, such as bulky abdominal disease, epitrochlear lymphade-nopathy, or hypercalcemia. CRs were attained by 67% and 85% of patients in the LDHD and NSLD groups, respectively: median survival had not been reached in either group with a median of 14 years of follow-up. Lymphocyte-depleted Hodgkin's disease, adequately treated, is in our limited group of patients no worse than other histopathologic subtypes of Hodgkin's disease. The erroneous inclusion of patients with high-grade NHLs into this subtype of Hodgkin's disease may be one reason for earlier literature reports of its more aggressive nature. The diagnosis of LDHD should be made cautiously, particularly in patients with clinical features that are unusual for Hodgkin's disease at presentation.

Long-term follow-up of ovarian function in women treated with MOPP chemotherapy for Hodgkin's disease

Twenty-seven women previously treated with MOPP (mechlorethamine, vincristine, procarbazine, prednisone) chemotherapy were evaluated to determine the status of ovarian function. All patients had completed therapy a median of nine years earlier and had a median age of 30 years at the time of evaluation. Persistent amenorrhea has occurred in 11 of 24 patients (46 percent) treated with MOPP alone or MOPP plus radiation excluding the pelvis. Of patients with amenorrhea, 89 percent were older than age 25 at the time of treatment. In contrast, 80 percent of patients younger than age 25 at treatment continue to menstruate regularly. The time from diagnosis to amenorrhea was significantly shorter in the older patients (p = 0.001). Evaluation of serum gonadotropin and estradiol levels confirms ovarian failure as the cause of amenorrhea in all patients. Overall, these 27 patients have borne 13 normal children subsequent to chemotherapy. This long-term follow-up study demonstrates that chemotherapy-induced ovarian failure is age-related, that ovarian failure is often gradual in onset following the completion of chemotherapy and that, to date, the children born of women treated with this chemotherapy regimen appear to be entirely normal.
