Fulminant Hepatic Failure as the Initial Presentation of Hodgkin's Disease and Liver Transplantation: A Case Report.

BACKGROUND: Hodgkin's lymphoma (HL) or Hodgkin's disease is a B-cell neoplasm, characterized by affecting the lymph nodes or extranodal lymphoid tissue. Includes two distinct entities: classical HL (95%) and lymphocyte-predominant nodular HL. This disease presents as cervical and intrathoracic lymph node growth in 60-90%, however, presentation due to liver infiltration is extremely rare. Around 30% of patients manifest the disease with a picture of general malaise based on fever, night sweats, weight loss and chronic pruritus. THE CASE: We present the case of a 13-year-old female, who started with an insidious condition that evolved to fulminant hepatic failure of unknown etiology (Table 1), it was decided to perform an orthothopic liver transplant, the histopathological analysis of the explant and a lymph node reported mixed cellularity Hodgkin's disease. Subsequently, the hematology service requested a lumbar puncture, with no evidence of infiltration. It was decided to initiate six cycles of chemotherapy with BEACOPP scheme, evolving without complications and achieving a complete response eleven months later; currently, she has been free of disease for three years. CONCLUSION: The cause remains unknown for this disease, so an early diagnosis and having different treatment options are the key points to combat this disease. Even though having a diagnosed neoplasm is a contraindication for receiving a liver transplant at present, the diagnosis was not available at that time, and because of her clinical situation, she met the criteria for liver transplantation. In the future, it could be essential to individualize each case to weigh the risks and benefits of carrying out the transplant or not.

Rare association of Visceral leishmaniasis with Hodgkin's disease: A case report

We present here a case of young male with complaints of fever and swelling in the neck for eight months. History of progressive weakness associated with weight loss was present. Physical examination revealed pallor, multiple enlarged cervical lymph nodes and hepatosplenomegaly. Investigations showed pancytopenia, hyperglobinemia and Leishman-Donovan bodies on bone marrow aspiration. Serological test confirmed diagnosis of visceral leishmaniasis. However, cervical lymph node aspiration and biopsy were suggestive of Mixed cellularity Hodgkin's disease. This made it a very rare case of Leishmaniasis as an opportunistic infection in a patient of pre-chemotherapy Hodgkin's disease. There was marked improvement in haematological profile and regression of hepatosplenomegaly with Amphotericin B treatment followed by favourable response to chemotherapy. The case emphasizes the suspicion for leishmaniasis as a masquerader and as an opportunistic infection in haematological malignancies.

Utilization of radiation therapy in early-stage Hodgkin disease and its impact on survival

8511 Background: Despite numerous randomized trials confirming the benefit of consolidation radiation therapy (RT) in the management of early stage Hodgkin disease (HD), utilization of RT in this setting remains variable. We performed a population-based analysis to assess the utilization of RT and its impact on overall and cause specific survival. Methods: The surveillance, epidemiology and end results (SEER) registry was used to identify patients aged 15–75 years diagnosed between 1990–2004 with early stage (stage I-IIA/B) HD, excluding nodular lymphocyte predominant HD. Kaplan-Meier analysis was performed to evaluate the effect of RT on overall survival (OS) and cause-specific survival (CSS). Subgroup survival analyses were also performed by era of treatment (1990–1997 and 1998–2004), sex, and patient age (<30, 30–50, and >50 years). Results: A total of 9729 patients met inclusion criteria. Median age of all patients was 34 years. The majority (71.3%) had nodular sclerosis (NS) type HD. By clinical stage, 3399 (34.9%) were stage I, and 6330 (65.1%) were stage II. 5352 patients (55%) received RT. RT was more likely to be employed during the early era of treatment, in younger patients, females, non-Blacks, and in NS, mixed cellularity and lymphocyte-rich HD. For the entire cohort, RT was associated with a significant (p<0.001) improvement in OS and CSS (hazard ratio of 0.537 and 0.437, respectively). The benefit of RT for OS and CSS remained significant for all subgroups analyzed including the era of treatment, sex, and age (p≤0.001). Conclusions: In this large population-based series of early stage HD patients, the use of RT is associated with a significant OS and CSS benefit across all subgroups. Current efforts in clinical trials have aimed at decreasing the utilization of RT among this patient population. This shift in practice is reflected in the data presented here. The omission of RT from the treatment paradigm, however, appears to be related with diminished survival. No significant financial relationships to disclose.

La TEP-TDM dans la maladie de Hodgkin : expérience clermontoise

The aim of this study was to evaluate the standardized uptake value (SUV) of 18FDG in Hodgkin's disease according to various histopathologic parameters as well as the impact of the examination on stadification and follow-up. A total of 37 patients profited from a pretherapeutic PET-CT. Standardized uptake value was calculated a posteriori. This one is higher in mixed cellularity Hodgkin's disease compared to nodular sclerosing Hodgkin's disease. In addition, the examination involved a change of stage in 35% of the cases compared to the injected CT. The specificity of the PET-CT at the end of the treatment was 96% and its exactitude of 93%, both significantly higher than those found in CT.

Epstein-Barr virus-associated Hodgkin's disease following renal transplantation

Post-transplant lymphoproliferative disorders (PTLD) have been recognized as a complication of immunosuppression and occur with a reported incidence of 1 to 8% of recipients receiving solid organ transplantation. PTLD are classified into two major categories, polymorphic and monomorphic PTLD. The majority of the monomorphic PTLD cases are non-Hodgkin's lymphoma of B-cell origin. Hodgkin's disease is not part of the typical spectrum of PTLD; however, it has been rarely reported. We describe a case of Hodgkin's disease following renal transplantation. A 41-year-old man developed right cervical lymphadenopathy following renal transplantation 116 months previously for chronic renal failure of unknown origin. He had been taking cyclosporine, mycophenolate mofetil and prednisone. A lymph node biopsy revealed mixed cellularity Hodgkin's disease. Immunohistochemical staining was positive for CD30 and EBV-latent membrane protein-1. No other site of disease was identified. The immunosuppressive agents were reduced (mycophenolate mofetil was discontinued, cyclosporine dose reduced from 200 mg to 150 mg and prednisone continued at 5 mg). After 2 cycles of ABVD followed by radiation therapy (3600 cGy), he achieved complete remission.

An Unusual Case of Spontaneous Remission of Hodgkin's Disease after a Single Cycle of COPP-ABV Chemotherapy Followed by Infectious Complications

Advanced Hodgkin's disease is usually treated with six or more cycles of combination chemotherapy. Spontaneous regression of the cancer is very rarely reported in patients with Hodgkin's disease. We present an unusual case of a patient with Hodgkin's disease who experienced complete remission with a single cycle of chemotherapy, followed by pneumonia. The case was a 36-year-old man diagnosed with stage IVB mixed cellularity Hodgkin's disease in November 2000. After treatment with one cycle of COPP-ABV (cyclophosphamide, vincristine, procarbazine, prednisone, doxorubicin, bleomycin, and vinblastine) chemotherapy without bleomycin, the patient developed interstitial pneumonia and was cared in the intensive care unit (ICU) for two months. Follow-up chest computerized tomography (CT), performed during the course of ICU care, revealed markedly improved mediastinal lymphomatous lesions. Furthermore, follow-up whole body CT and 18-fluorodeoxyglucose positron emission tomography showed complete disappearance of the lymphomatous lesions. Four years later, the patient is well and without relapse. This report is followed by a short review of the literature on spontaneous regression of Hodgkin's disease. To the best of our knowledge, this is the first case report of spontaneous remission of Hodgkin's disease in Korea.

Geographical and ecological analyses of childhood acute leukaemias and lymphomas in north-west England.

Childhood leukaemias and lymphomas have been associated with exposure to environmental factors, including infections, which show geographical variation. This study examined the geographical distribution of the incidence of acute leukaemia and lymphoma using Manchester Children's Tumour Registry (MCTR) data 1976-2000. A total of 910 children were included, all of whom had histologically and/or cytologically verified leukaemia or lymphoma. At the time of their diagnoses, all the children were aged 0-14 years and were resident in the counties of Greater Manchester or Lancashire. Standardized morbidity ratios were calculated. Poisson regression was used to examine the relationship between incidence rates and small-area (census ward) population density, ethnic composition and deprivation index. There was a monotonic relationship between acute lymphoblastic leukaemia (ALL) incidence and population density (P = 0.05). Higher rates were seen in more densely populated areas. There was evidence for a monotonic relationship between the incidence of the mixed cellularity subtype of Hodgkin's disease (HD) and the Townsend deprivation score (P = 0.001). Markedly higher incidence was associated with greater levels of unemployment and household overcrowding. The results for ALL and mixed cellularity HD support the involvement of environmental factors, such as infections, in disease aetiology.

Clusterin Expression in Malignant Lymphomas: A Survey of 266 Cases

Clusterin expression has been reported to be characteristic of systemic anaplastic large cell lymphoma and usually negative in cutaneous anaplastic large cell lymphoma as well as other lymphoma types. We surveyed clusterin expression using immunohistochemical methods in 266 cases of non-Hodgkin's lymphoma and Hodgkin's disease to further assess the diagnostic utility of this marker. Clusterin immunostaining was observed in 40 of 49 (82%) systemic anaplastic large cell lymphomas and 12 of 29 (41%) cutaneous anaplastic large cell lymphomas. Clusterin also was expressed in 5 of 43 (12%) diffuse large B-cell lymphomas (4 of 5 CD30+), 1 of 14 (7%) peripheral T-cell lymphomas, 1 of 32 (3%) cases of nodular sclerosis Hodgkin's disease, and 1 case of mycosis fungoides in large cell transformation. Clusterin was negative in all other neoplasms assessed including follicular lymphoma of all grades (n = 24), mantle cell lymphoma (n = 13), marginal zone B-cell lymphoma (n = 12), precursor T-cell or B-cell lymphoblastic leukemia/lymphoma (n = 10), mixed cellularity Hodgkin's disease (n = 8), chronic lymphocytic leukemia/small lymphocytic lymphoma (n = 7), Burkitt lymphoma (n = 7), mycosis fungoides (n = 4), nodular lymphocyte predominant Hodgkin's disease (n = 3), lymphoplasmacytic lymphoma/Waldenstrom macroglobulinemia (n = 2), and plasmacytoma (n = 2). We conclude that clusterin is a marker of anaplastic large cell lymphoma and that addition of clusterin to antibody panels designed to distinguish systemic anaplastic large cell lymphoma from classical Hodgkin's disease is useful. However, clusterin is also positive in a substantial subset of cutaneous anaplastic large cell lymphomas, a smaller subset of diffuse large B-cell lymphomas, and rarely in cases of peripheral T-cell lymphoma and nodular sclerosis Hodgkin's disease.

Analysis of Mismatch Repair Defects in the Familial Occurrence of Lymphoma and Colorectal Cancer

Hereditary non-polyposis colon cancer (HNPCC) is an autosomal dominant disorder featuring familial clustering of colorectal and/or endometrial cancer, and other malignancies. Except for a rare case report, Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL) have not been considered part of HNPCC. Recent murine models for HNPCC have shown an increased incidence of B- and T-cell lymphoma, as well as tumors of the gastrointestinal tract and other organ systems, involving defects in genes resulting in faulty mismatch repair (MMR) of DNA. These MMR genes include MLH 1, MSH 2, MSH 3, MSH 6, PMS 1 and PMS 2. We sought to analyze the occurrence of NHL and HD in families with clusters of colorectal cancers (CRC). Probands from 21 kindreds were classified as HNPCC (3), HNPCC-like (5), and HNPCC-variant (13); seen and followed by Clinical Genetics at Memorial Hospital the kindreds were assessed for the occurrence of NHL or HD. Of the 21 pedigrees, a total of 37 patients were identified who were diagnosed with leukemia, lymphoma, or HD. Fourteen of the 37 patients with a diagnosis of NHL or HD were further classified and showed varying histologies ranging from chronic lymphocytic leukemia/small lymphocytic lymphoma (2), mycosis fungoides (1), follicular lymphoma (1), extranodal marginal zone lymphoma of MALT type (2), diffuse large B-cell lymphoma (4), nodular sclerosis HD (3), and mixed cellularity HD (1). Microsatellite instability studies were performed on 6 cases but none showed evidence of replication error repair defects. Immunohistochemical stains performed on paraffin sections from these 6 representative cases showed differential protein expression of MLH1, MSH2, MSH6, and PMS2 when compared to normal reactive tissues from the same patient but showed no significant differences when compared to controls of non-familial, sporadic lymphomas. These results suggest that lymphomas arising in the setting of familial CRC do not bear the molecular hallmarks of HNPCC. Further studies are needed to explain the differential patterns of expression of RER-associated proteins in lymphomas, as well as the association of lymphomas and possibly renal cell cancers in a subset of kindreds in which CRC clustering is evident.

Feline Hodgkin's-like lymphoma: 20 cases (1992-1999).

We identified 20 cases of feline lymphadenopathy that conform to many clinical and histologic manifestations of human Hodgkin's disease. Histologic subtypes encountered included lymphocyte predominance (nine cases), mixed cellularity (nine cases), and nodular sclerosis (two cases). Two cases were not easily classified; fibrous bands were present, but the absence of nodules supported a subclassification of mixed cellularity Hodgkin's disease. Immunohistochemical staining of the tissues using antibodies against the pan T-cell antigen CD3, the human B-lymphocyte antigen 36 (BLA.36), the pan B-lymphocyte and plasma cell marker CD79a, and a myeloid antigen (MAC387) confirmed the phenotypic heterogeneity of the tumor. Classic Reed-Sternberg (RS) cells and mononuclear, multinucleate, and lacunar cell variants did not stain with any of the antibodies used. In contrast, lymphohistiocytic RS variants (L+H cells) reacted positively to BLA.36 and CD79a B-cell markers. Eighteen of 20 affected cats were > or = 6 years of age (range, 1-14 years). A sex predilection could not be identified. These findings support the existence of Hodgkin's-like lymphoma in the cat. Proper identification of this disease in the cat will enable further characterization of clinical features and biologic behavior to determine whether there are significant differences in the treatment and prognosis of feline Hodgkin's-like lymphoma compared with non-Hodgkin's lymphoma.

Tissue Eosinophilia in Relation to Immunopathological and Clinical Characteristics in Hodgkin's Disease

Eosinophils frequently infiltrate tissues involved by Hodgkin's disease (HD), and blood eosinophilia is frequently observed. However, the clinical significance and the mechanisms underlying eosinophilia need further elucidation. In this study the grade of eosinophilic infiltration (Eol) was evaluated in biopsies from 259 HD-patients. In a selected group (n = 32), the numbers of Hodgkin-Reed-Stemberg (HRS)-cells were counted, and the phenotype of small lymphocytes, the expression of cytotoxic lymphocyte-associated proteins, CD3-chain, HLA-DR, proliferation markers, latent membrane protein 1 (LMP-1) and blood lymphocyte function were evaluated. Samples from 88 HD patients (34%) showed high Eol. Significantly higher Eol was seen in nodular sclerosis 2 (NS2; p < 0.001), bulky disease (p < 0.05) and in patients < 50 years (p < 0.05). Patients with high EoI did not differ from the remainder with regard to distribution of sex, stage, B-symptoms, blood lymphocyte function and outcome. HRS-cells were significantly more frequent in NS HD as compared to mixed cellularity (MC) (p < 0.001) irrespective of EoI. LMP-1-expression, proliferative fraction and phenotypes of small lymphocytes did not differ between the cases with low and high EoI, respectively. MC HD samples had significantly higher numbers of small cells positive for CD8 (p < 0.01), T-cell intracellular antigen-1 (p < 0.01) and Granzyme B (p < 0.05) than NS. LMP-1-positive cases had significantly higher frequency of CD8-positive cells than LMP-1-negative. In conclusion, high EoI remains a feature of certain clinical subgroups of HD.However, there was no association between the degree of EoI and numbers of HRS-cells, phenotypes of small lymphocytes, EBV status and clinical outcome. Determination of EoI is of limited diagnostic and prognostic clinical value in HD. However, the differences in small cell distribution of CD8, TLA-1, GrB and CDS7 between the histopathological groups and between LMP-1-expressing/non-expressing cases may contribute to our understanding of the biology of the disease.

Primary Adenoidal Hodgkin's Disease: Report of a Case with an Unusual Morphology and Review of the Literature.

The nasopharyngeal lymphoid tissue (adenoids) is an uncommonly reported primary site for Hodgkin's disease. We report a case of primary adenoidal, interfollicular, epithelioid cell-rich variant of mixed cellularity Hodgkin's disease. The combination of an interfollicular pattern and richness of epithelioid histiocytes made it very difficult to make the diagnosis of Hodgkin's disease without the help of immunohistochemistry. To our knowledge, only 39 cases of Hodgkin's disease primarily involving the Waldeyer's ring have been reported in the English literature, 24 of these primarily involving the adenoids. Our case shows the difficulty encountered in making the diagnosis when a very unusual morphologic appearance of Hodgkin's disease is seen at a rare presentation site. The appropriate immunohistochemical work-up should be performed in unusual lymphohistiocytic proliferations involving the Waldeyer's ring. Int J Surg Pathol 8(3):241-246, 2000

Laparoscopic Transposition of the Ovaries: Is It Effective to Preserve Ovarian Function Before Pelvic Node Irradiation in Pediatric Patients?

The potential disadvantages of elective pelvic node irradiation in young girls with Hodgkin's disease include ovarian failure and possible future infertility. Prophylactic laparoscopic transposition of the ovaries from the radiation field, or oophoropexy, can spare ovarian function in many girls. The authors report the case of a laparoscopic bilateral oophoropexy performed in a 9-year old girl suffering from mixed-cellularity Hodgkin's disease. Laparoscopy was performed using four trocars: one for a 10-mm 0° telescope placed infraumbilically, a 10-mm trocar above the symphysis pubis, and two 5-mm trocars at the lower left and right quadrants. The ovaries were transposed by placing two nonresorbable sutures through the utero-ovarian ligaments and posterior part of the uterus. Two titanium clips were placed to help locate the ovaries postoperatively. Surgery lasted 45 min. There were no intra- or postoperative complications. The patient was discharged from the hospital after 24 h. One year after the first intervention, at the end of radiotherapy, a second laparoscopic exploration was performed to evaluate and reposition the ovaries under visual guide. After a 3-year follow-up, hematologic evaluation of the patient's hormone levels and an ultrasonographic exam showed severe impairment of the ovarian function. The authors believe that laparoscopic oophoropexy is a feasible and easy procedure to use on children, although on the basis of these data, it may not always be sufficient to prevent ovarian failure secondary to radiotherapy.

Detection of Clonal Hodgkin and Reed-Sternberg Cells With Identical Somatically Mutated and Rearranged VH Genes in Different Biopsies in Relapsed Hodgkin’s Disease

Hodgkin's disease (HD) represents a malignant lymphoma in which the putative malignant Hodgkin and Reed-Sternberg (H-RS) cells are rare and surrounded by abundant reactive cells. Single-cell analyses showed that H-RS cells regularly bear clonal Ig gene rearrangements. However, there is little information on the clinical evolution of HD in a given patient. In this study, we used the single-cell polymerase chain reaction (PCR) to identify H-RS cells with clonal Ig gene rearrangements in biopsy specimens of patients with relapsed HD. The obtained clonal variable region heavy-chain (VH) gene rearrangements were used to construct tumor-clone-specific oligonucleotides spanning the complementarity determining region (CDR) III and somatically mutated areas in the rearranged VH gene. A number of biopsies were obtained during a period of 3 years from two HD patients. H-RS cells with identical VH rearrangements were detected in two separate infiltrated lymph nodes from one patient with nodular sclerosis HD. In a second patient with mixed cellularity HD subtype, clonal VH rearrangements with identical sequences were detected in infiltrated spleen and two lymph node biopsies. Despite the high sensitivity of the PCR method used (one clonal cell in 10(5) mononuclear cells), residual H-RS cells were not found in peripheral blood, leukapheresis material, purified CD34(+) stem cells or bone marrow. The results show that different specimens from relapsed patients suffering from classical HD carry the same clonotypic IgH rearrangements with identical somatic mutations, demonstrating the persistence and the dissemination of a clonal tumor cell population. Thus, PCR assays with CDRIII-specific probes derived from clonal H-RS cells are of clinical importance in monitoring the dissemination of HD and tumor progression and could be useful for analysis of minimal residual disease after autologous stem cell transplantation.

The origin of Hodgkin and Reed/Sternberg cells in Hodgkin's disease.

One of the characteristic features of Hodgkin's disease (HD) is the presence of a small population of often bizarre-looking large mono- or multinucleated Hodgkin and Reed-Sternberg (HRS) cells within the affected tissue. Recent cytogenetic investigations, studies of Epstein-Barr virus (EBV) genomes present in HRS cells, and analyses of Ig gene rearrangements amplified from single, micromanipulated HRS cells show that these cells largely represent clonal populations. The finding of Ig gene rearrangements in HRS cells in most cases of HD identifies B cells as the precursors of HRS cells in most if not all cases. Furthermore, the presence and pattern of somatic mutations within the rearranged Ig genes show that HRS cells in classical (i.e. nodular sclerosis, mixed cellularity, and lymphocyte depletion HD) as well as lymphocyte predominant (LP) HD originate from germinal center (GC) B cells. Ongoing somatic mutation and evidence for selection link HRS cells from LP HD to a mutating, antigen-selected GC B cell. In classical HD, the finding of "crippling" mutations and lack of stringent selection for antigen receptor expression suggests that in this case HRS cells are derived from a compartment of GC B cells that were destined to die but escaped apoptosis by some transforming event. One candidate for the latter is EBV infection.

What causes Hodgkin's disease in children?

Hodgkin's disease is one of the commonest cancers of older children and adolescents, but little is known about its aetiology. Recent data, particularly in descriptive epidemiology and virology, tend to confirm the 'two-disease' hypothesis. Mixed cellularity Hodgkin's disease is more common, especially at younger ages, in poorer socioeconomic environments, whereas nodular sclerosing Hodgkin's disease has a higher incidence in more affluent societies. Approximately three-quarters of childhood Hodgkin's disease, and a higher proportion of the mixed cellularity subtype, may be a rare response to Epstein-Barr virus infection, together with an unidentified cofactor related to the degree of affluence of the population. Other infectious agents may be implicated in some cases. The already low incidence, especially of nodular sclerosis, among populations of East Asian ethnic origin and the high incidence, especially of mixed cellularity, among some populations of South Asian origin are apparently independent of socioeconomic status. This ethnic variation in risk suggests that genetic predisposition also plays a role. Detailed HLA studies may help to elucidate the complex variations between populations in the risk of Hodgkin's disease and its principal subtypes.

Hodgkin's disease: Correlation of clinical characteristics with probabilities for negative lymphangiogram vs. negative laparotomy findings in patients with Stage I supradiaphragmatic presentations vs. those in patients with Stage II

At a time both when late complications and second malignancies have become a growing concern and when staging laparotomy has been largely abandoned and comparative studies for staging Hodgkin's disease by state of the art computed tomography (CT) vs. lymphangiography have revealed minimal differences in results for these procedures, our purpose for undertaking this study was twofold. Our initial reason was to determine and compare probabilities for negative abdominal findings for patients with Stage I presentations with those for patients with Stage II as determined by lymphangiography and subsequently by laparotomy for those patients who had negative lymphangiograms. Our second reason, being an extension of the first, was to create a resource that can be used in conjunction with other information for arriving at appropriate treatment decisions including giving either more or particularly less than standard institutional therapy and especially with respect to the abdomen. Data on 714 patients with prelymphangiogram Stage I-II upper torso presentations of Hodgkin's disease were entered prospectively in our database between 1968 and 1987. Twenty-eight with lymphocyte predominant disease, who had both negative lymphangiogram and negative laparotomy findings and 17 with questionable diagnoses of lymphocyte-depleted or unclassified disease were excluded from subsequent analyses of 669 patients with nodular sclerosis (NS) and mixed cellularity (MC) diagnoses. Stage I: in final logistic models, negative lymphangiogram findings were associated strongly with a combination of no constitutional symptoms and nodular sclerosis histology, whereas negative laparotomy findings correlated strongly with a combination of no constitutional symptoms and female sex. Predicted probabilities depended on the ratios of favorable to unfavorable characteristics. Stage II: in final logistic models, negative lymphangiogram findings were associated strongly with a combination of no constitutional symptoms, nodular sclerosis histology, age <40 years, and <4 involved sites, whereas negative laparotomy findings correlated strongly with a combination of <4 involved sites and mediastinal disease. Predicted probabilities again depended on the ratios of favorable to unfavorable characteristics. This study demonstrated that probabilities for negative abdominal findings for patients with supradiaphragmatic presentations of NS and MC Hodgkin's disease depended on: 1) whether the disease presented as Stage I or as Stage II; 2) whether staging was limited to a lymphangiogram or whether it included a laparotomy; and 3) or whether the clinical features associated with the presenting stage and methods of staging were favorable or unfavorable.

Does histology influence outcome in childhood Hodgkin's disease? Results from the United Kingdom Children's Cancer Study Group.

Histology has been identified as an important prognostic factor in Hodgkin's disease (HD) in adults. Information regarding the impact of histology on outcome in childhood HD is scarce. This study determines the effect of histology on the overall survival (OS) or progression-free survival (PFS) in a national series of children treated in a standardized manner. The results of treatment of 331 assessable patients, treated between January 1, 1982 and June 30, 1992, in the United Kingdom Children's Cancer Study Group (UKCCSG) Hodgkin's study I were reviewed to evaluate OS, PFS, and deaths according to stage and histology. Treatment was either involved-field radiation alone (stage IA) or chlorambucil, vinblastine, procarbazine, and prednisolone (ChlVPP) chemotherapy with or without mediastinal radiation. All were clinically staged at diagnosis. Nodular sclerosing (NS) HD was the most common histologic subtype (155 of 331 patients [47%]) and was uniformly distributed through all stages. Lymphocyte-depletion (LD) HD was extremely uncommon (< 1%). Mixed-cellularity (MC) HD had the highest relapse rate, but this was only significant (P < .05) in stage I patients who received local irradiation alone. There was no other statistically significant difference in OS and PFS between the various histologic subtypes. Multivariate analysis for PFS and OS confirmed that stage was the most important prognostic factor and that histology did not have an effect after stratification by stage. This study demonstrates that with effective multiagent chemotherapy, histologic subtype does not influence outcome. The high relapse rates in stage I MC subtype indicates that MC HD is biologically aggressive and systemic treatment with or without local irradiation may be indicated. The high relapse rate in stage IV patients appeared to be independent of histology.

Activated Cytotoxic T Cells as Prognostic Marker in Hodgkin's Disease

AbstractAlthough the results of treatment of Hodgkin's disease (HD) have improved considerably in the last decades, the disease remains fatal in a minority of patients. We have recently shown that numbers of activated cytotoxic T cells (CTLs), present in tumor biopsy specimens, differ considerably among individual HD patients. Because CTLs are the major effector cells in elimination of neoplastic cells, we investigated whether the number of activated CTLs is related to the clinical outcome of the individual patient with HD. Activated CTLs present in tumor biopsy specimens of patients with nodular sclerosis or mixed cellularity HD were identified by immunohistochemistry using an antibody directed against granzyme B (GrB), a major constituent of the cytotoxic granules of activated CTLs and natural killer cells, and an antibody directed against CD8. The presence of a high percentage of GrB+ lymphocytes was found to be an unfavorable prognostic marker. The large majority of GrB+ cells were also CD8+, indicating that these cells are activated CTLs. Prognosis was found to decrease with increasing percentages of GrB+ lymphocytes. Optimal discrimination between patients with good and poor prognosis was obtained when the threshold was set at 15% GrB+ cells; 6 of 10 patients with ≥15% GrB+ lymphocytes died as a result of the disease, as compared with 6 of 70 patients with less than 15% GrB+ lymphocytes (P < .0001). In stage-2 patients, the percentage of GrB+ lymphocytes retained its predictive value in a multivariate analysis including histology, sex, age, erythrocyte sedimentation rate, and the presence of B symptoms as covariables. In addition, patients with ≥15% GrB+ lymphocytes had a shortened progression-free survival time (P = .002). We conclude that a high percentage of activated CTLs present in biopsy material of HD patients is a strong indicator for an unfavorable clinical outcome.
