Prognostic factors for disease progression after high-dose chemotherapy and autologous hematopoietic stem cell transplantation for recurrent or refractory Hodgkin's lymphoma.

Our purpose was to study the risk factors associated with disease progression after high-dose chemotherapy followed by autologous stem cell transplantation in patients with recurrent or refractory Hodgkin's lymphoma (HL). We analyzed the long-term outcome of 184 patients with recurrent or refractory HL who underwent autologous hematopoietic stem cell transplantation. At the time of transplantation, 82 patients were in first relapse or second remission, 46 patients were refractory to the primary induction chemotherapy, and 56 patients were beyond first relapse or second remission. In 64 patients, the disease had proved refractory to the chemotherapy regimen administered immediately prior to transplantation. The median follow-up of patients who were alive and free of disease at the time of this report was 8.9 years (range, 0.1-19.0 years). At 10 years, the overall and disease-free survival rates were 34% (95% CI 27-42) and 29% (95% CI 22-36) respectively. The major cause of treatment failure was disease relapse. Chemotherapy resistance prior to transplantation, advanced stage, and higher number of chemotherapy regimens administered prior to transplantation were adverse prognostic factors for disease progression. We conclude that autologous transplantation is an effective salvage treatment for recurrent HL.

Mammographic features and correlation with biopsy findings using 11-gauge stereotactic vacuum-assisted breast biopsy (SVABB).

BACKGROUND: Mammograms are assigned a BI-RADS (Breast Imaging Reporting and Data System) category, which indicates the level of suspicion for cancer. OBJECTIVES: (i) To evaluate the use of BI-RADS categories in a non-academic radiology practice based in a community hospital compared with local radiology private offices; (ii) to determine positive predictive value (PPV), sensitivity and specificity of mammograms; and (iii) to explore the correlation of BI-RAD 3-5 and lesion description with diagnosis of cancer. PATIENTS AND METHODS: We performed 947 SVABBs (stereotactic vacuum-assisted breast biopsies) on 911 patients with BI-RADS 3-5. Lesions were classified as: 1=microcalcifications; 2=asymmetric density; 3=circumscribed mass; and 4=spiculated mass. RESULTS: BI-RADS category correlated with diagnosis of breast cancer (atypia excluded): category 3=4%; category 4=15%; and category 5=79%. The PPV of BI-RADS 4 and 5 for breast cancer or atypia was 20%, in contrast to 5% for BI-RADS 3. Sensitivity and specificity were 95% and 19%, respectively. For BI-RADS 3 without microcalcifications only 3% were positive, in contrast to 8% for remainder. CONCLUSIONS: First, there is a stepwise increase in cancer for each of the BI-RADS categories 3-5. Secondly, in BI-RADS 3 with microcalcifications, a biopsy is indicated according to our findings. Finally, the sensitivity of mammograms is 95% but the specificity is 19%.

Asymptomatic Waldenstrom's macroglobulinemia.

A study was undertaken to evaluate the frequency and natural history of disease in patients with asymptomatic Waldenstrom's macroglobulinemia (WM). Among 132 consecutive, newly diagnosed patients with monoclonal IgM, 82 (27%) had symptomatic WM indicated by anemia, lymphadenopathy, or splenomegaly. Thirty-one patients had similar clinical features but were asymptomatic and followed without therapy until disease progression. There were 19 patients with monoclonal gammopathy of undetermined significance of IgM type (MGUS). In comparison to overt WM, patients with asymptomatic WM had significantly higher hemoglobin (Hgb) level (median, 12.1 v 9.7 g/dL), lower serum beta(2)-microglobulin (B(2)M) level (median, 2.4 v 3.4 mg/L), and similar IgM peaks (median, 2.2 and 1.8 g/dL). The IgM component was 3.6 g/dL or less in all patients with asymptomatic disease. For asymptomatic WM, median time to disease progression was 6.9 years with rare morbidity. Prognostic factors for early progression were Hgb <11.5 g/dL, B(2)M >or= 3.0 mg/L, and IgM peak >3.0 g/dL. Combinations of these variables defined three risk groups for progression with markedly different median times to progression of >5 years, 2 years, and 0.5 year, respectively. Response rate and survival after institution of treatment were similar to those of patients treated promptly for overt disease. We conclude that, among patients with WM, 27% were asymptomatic with slow disease progression before the need for chemotherapy. Since disease outcomes after treatment were similar to those of patients treated at diagnosis, patients with asymptomatic disease should be identified and followed without treatment for as long as risks of complications remain low.

Long-term results favor allogeneic over autologous hematopoietic stem cell transplantation in patients with refractory or recurrent indolent non-Hodgkin's lymphoma.

BACKGROUND: The aim of this study was to compare the outcomes of high-dose therapy (HDT) and allogeneic versus autologous hematopoietic stem cell transplantation (SCT) in patients with refractory or recurrent indolent non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS: From January 1991 to March 2000, 112 patients underwent HDT followed by either autologous (68 patients) or allogeneic (44 patients) SCT for refractory or recurrent indolent NHL. Prior conventional chemotherapy had failed in all patients. RESULTS: The two groups were similar with respect to age at transplantation, gender, histological subtypes, number of chemotherapy regimens received before transplantation and International Prognostic Index scores. The median time from diagnosis to transplantation was longer in the autologous than in the allogeneic SCT group (46 versus 27 months, P = 0.002). In the allogeneic SCT group the median follow-up time was 53 months (range 21-113), and the overall survival (OS) and disease-free survival (DFS) rates were 49% and 45%, respectively. After a median follow-up time of 71 months (range 22-109), in the autologous SCT group, the OS and DFS rates were 34% and 17%, respectively. Patients who underwent autologous SCT were more likely to have chemosensitive disease (P <0.001) and were more likely to be in complete remission at the time of transplantation (P = 0.001) than those who underwent allogeneic SCT. However, the probability of disease progression was significantly higher in the autologous SCT group than in the allogeneic SCT group (74% versus 19%, P = 0.003). CONCLUSIONS: Patients who undergo HDT with allogeneic SCT for refractory or recurrent indolent NHL have lower relapse rates but higher treatment-related mortality rates than patients who undergo autologous SCT. However, with the development of non-myeloablative preparative regimens, which can decrease treatment-related mortality, patients with recurrent indolent NHL should be considered for controlled trials of allogeneic transplantation if they have a human leukocyte antigen-identical donor.

Trimetrexate in relapsed T-cell lymphoma with skin involvement.

PURPOSE: Methotrexate (MTX) is active against lymphomas, but transport or polyglutamylation mutations confer MTX resistance. Because trimetrexate (TMTX) enters cells by passive diffusion and is not polyglutamylated, its activity in relapsed T-cell lymphoma was investigated. PATIENTS AND METHODS: Eligible patients had histologically confirmed relapsed T-cell lymphoma involving the skin, had received more than one previous regimen, were older than 16 years, had normal organ function, and had no CNS disease or serious infections, including human immunodeficiency virus. TMTX (200 mg/m(2)) was given intravenously every 14 days without topical or systemic corticosteroids. Patients who responded received up to 12 doses. RESULTS: Twenty patients were assessable for response. Median age was 59 years (range, 45 to 87 years); 13 patients were men. Three patients had anaplastic large-cell lymphoma, 15 had mycosis fungoides or Sézary syndrome (14 with large-cell transformation), and two had peripheral T-cell lymphoma. Serum lactate dehydrogenase was high in 35%, and beta-2 microglobulin was more than 3.0 mg/L in 35% of patients. The median number of previous regimens was three (range, two to 15) and included MTX in five patients. Disease was refractory to the regimen immediately preceding TMTX in 85% of patients. Responses were complete in one and partial in eight patients (overall response rate, 45%). Two of five patients previously treated with MTX responded. Grade 3 or 4 mucositis was observed after 4%, infection after 3%, neutropenic fever after 6%, neutrophils less than 100/microL after 4%, and platelets less than 10,000/microL after 3% of TMTX doses. CONCLUSION: TMTX is active with acceptable toxicity in this population and merits further investigation.

Is there an increased rate of additional malignancies in patients with mantle cell lymphoma?

PURPOSE: To examine the frequency of additional neoplasms preceding and following the diagnosis of mantle cell lymphoma (MCL). PATIENTS AND METHODS: A total of 156 patients with MCL treated on the hyperfractionated cyclophosphamide, vincristine, doxorubicin and dexamethasone alternated with methotrexate and cytosine arabinoside (Hyper-CVAD/M-A) program with or without rituximab from 1994 to 2000 were the subjects of this report. RESULTS: These patients were followed for a median time of 26 months, and a total of 32 (21%) additional neoplasms were diagnosed, 21 preceding the diagnosis of MCL and 11 following MCL. After excluding certain types of non-invasive neoplasms, including basal cell carcinoma, meningioma and cervical intraepithelial neoplasia, we observed seven second malignancies after the diagnosis of MCL, and the 5-year cumulative incidence rate of second malignancy was 11%. The observed-to-expected (O/E) ratio was 7/0.07 = 100 [95% confidence interval (CI) 49.3 to 186.6; P <0.0001]. Of the 21 malignancies diagnosed prior to MCL, 16 were invasive and five non-invasive. There were a total of 10 urologic malignancies occurring before or after the diagnosis of MCL was established. CONCLUSIONS: Our findings suggest that there is an increased incidence of second malignancies in patients with MCL. In addition, the high number of cases with urinary tract cancer in our series may substantiate prior reports describing a possible association between lymphoma and urologic malignancies.

Primary cutaneous non-Hodgkin's lymphoma with aggressive histology: inferior outcome is associated with peripheral T-cell type and elevated lactate dehydrogenase, but not extent of cutaneous involvement.

BACKGROUND: The aim of this study was to explore the association between extent of cutaneous involvement, presenting features and progression-free survival (PFS) in patients with primary cutaneous non-Hodgkin's lymphoma (PCNHL) of aggressive histology. METHODS: Previously untreated patients with localized or extensive PCNHL of aggressive histology, treated with combination chemotherapy, but excluding lymphoblastic lymphoma and mycosis fungoides and its variants, were reviewed retrospectively. RESULTS: We identified 53 patients, of whom 52 (35 males, 17 females) were treated with doxorubicin-based regimens. Median age was 52 years (range 25-81 years), and disease was localized and extensive in 37 and 16 patients, respectively. Twenty-four patients had diffuse large B-cell lymphoma, nine had grade 3 follicular lymphoma, 13 had peripheral T-cell lymphoma (PTCL; not otherwise specified) and seven had anaplastic large cell lymphoma (WHO classification). With a median follow-up of 101 months (range 2-237 months) for survivors, the 10-year PFS was 65 +/- 7% and overall survival was 72 +/- 8%. The first failure involved the skin in 33% of B-cell and 91% of relapsing T-cell lymphomas. Univariate analysis revealed that PTCL (P = 0.005), lymphopenia (P = 0.01) and high serum levels of beta(2)-microglobulin (P = 0.0006) and LDH (P = 0.002), but not extent of skin involvement, were associated with inferior PFS. Multivariate analysis revealed that only PTCL and high serum lactate dehydrogenase (LDH) were independently associated with inferior PFS. CONCLUSIONS: PTCL and elevated serum LDH level, but not extent of cutaneous involvement are associated with inferior PFS in aggressive PCNHL treated with combination chemotherapy.

Irinotecan in relapsed or refractory non-Hodgkin's lymphomas. Indications of activity in a phase II trial.

Because irinotecan (CPT-11, Camptosar) is a topoisomerase I inhibitor with a broad spectrum of antitumor clinical activity, we investigated its activity in relapsed or refractory non-Hodgkin's lymphomas (NHLs). Irinotecan at 300 mg/m2 i.v. was administered every 21 days with intensive loperamide management of diarrhea. Responders received up to six treatment cycles. Of 44 registered patients, 32 are evaluable for response. Seventeen patients had received one previous regimen, and 15 patients had received two. Disease was refractory to the regimen preceding irinotecan in 12 patients. At baseline, serum lactate dehydrogenase levels were high in 47% (14/30), and beta-2-microglobulin levels were higher than 3.0 mg/L in 29% (8/28) of patients. Responses were seen in 12 of 32 (38%) patients (95% confidence interval [CI] = 21%-56%). Response rates were 43% for seven indolent (95% CI = 10%-82%), 0% for three mantle cell (95% CI = 0%-71%), 44% for 18 relapsed aggressive (95% CI = 22%-69%), and 20% for five refractory aggressive NHLs (95% CI = 1%-72%). Grade 3/4 toxicities included myelosuppression, neutropenic fever, and diarrhea. Irinotecan appears active and relatively well tolerated in patients with relapsed aggressive or indolent NHL. Accrual to this study is continuing for better determination of response rates in all histologic subtypes of NHL.

Long-term results with radiotherapy for Stage I-II follicular lymphomas.

PURPOSE: To analyze the long-term results with radiotherapy (RT) for early-stage, low-grade follicular lymphomas. METHODS AND MATERIALS: From 1960 to 1988, 80 patients with Stage I (n = 33) or II (n = 47), World Health Organization Grade 1 (n = 50) or 2 (n = 30) follicular lymphoma were treated with RT. The lymph nodes or spleen were involved in 97% of cases. The maximal tumor sizes ranged from 0.5 to 11.0 cm (median 2.0). The RT fields encompassed only the involved Ann Arbor nodal region (involved-field RT) in 9% of the patients. The fields also included 1-3 adjacent, grossly uninvolved nodal regions (regional RT) in 54% of patients but were smaller than mantle or whole abdominopelvic fields. Mantle or whole abdominopelvic fields encompassing up to 6 grossly uninvolved regions (extended-field RT) were used in the remaining 37% of patients. The total RT doses ranged from 26.2 to 50.0 Gy given in daily 1.0-3.0-Gy fractions. RESULTS: The follow-up of the surviving patients ranged from 3.5 to 28.7 years (median 19.0). No recurrences were found >17.0 years after RT, with 13 patients free of disease at their last follow-up visit 17.6-25.0 years after treatment. In 58% of cases, death was not from follicular lymphoma. The 15-year local control rate was 100% for 44 lymphomas <3.0 cm treated with only 27.8-30.8 Gy (median 30.0 in 20 fractions). Progression-free survival was affected by the maximal tumor size at the start of RT (15-year rate 49% vs. 29% for lymphomas <3.0 cm vs. > or =3.0 cm, respectively, p = 0.04) and Ann Arbor stage (15-year rate 66% vs. 26% for Stages I and II, respectively, p = 0.006). Ann Arbor stage also affected the cause-specific survival (15-year rate 87% vs. 54% for Stages I and II, respectively, p = 0.01). No significant difference was found in overall survival between those treated with extended-field RT and those treated with involved-field RT or regional RT (15-year rate 49% and 40%, respectively, p = 0.51). The 15-year incidence rate of Grade 3 or greater late complications according to the Subjective, Objective, Management, and Analytical scale in patients treated with 26.2-30.8 Gy vs. 30.9-50.0 Gy was 0% and 6%, respectively. CONCLUSIONS: RT can cure approximately one half of Stage I and one quarter of Stage II, World Health Organization Grade 1 or 2 follicular lymphomas. Follicular lymphomas <3.0 cm can be controlled locally with doses of 27.8-30.8 Gy, and there is a trend toward a higher incidence of late complications with doses of >30.8 Gy. Doses of 25-30 Gy delivered in 15-20 fractions should be examined prospectively in patients with follicular lymphomas of <3.0 cm.

Functional expression of receptor activator of nuclear factor kappaB in Hodgkin disease cell lines.

The malignant Hodgkin and Reed-Sternberg (H/RS) cells of Hodgkin disease (HD) express several members of the tumor necrosis factor (TNF) receptor family, including CD30 and CD40, and secrete several cytokines and chemokines. However, little is known about what regulates cytokine and chemokine secretion in H/RS cells. Although H/RS cells are predominantly of B-cell origin, they frequently share phenotypic and functional features with dendritic cells (DCs). Previous studies reported that receptor activator of nuclear factor kappaB (NF-kappaB) (RANK), a member of the TNF receptor family, is expressed on DCs, and that RANK ligand (RANKL) enhances DC survival and induces them to secrete cytokines. This study reports that, similar to DCs, cultured H/RS cells expressed RANK. However, unlike DCs, H/RS cells also expressed RANKL. Soluble RANKL activated NF-kappaB and induced messenger RNA expression of interferon-gamma, interleukin-8 (IL-8), IL-13, IL-9, IL-15, and RANTES, in addition to the receptors for IL-9, IL-13, IL-15, and CCR4. RANKL increased IL-8 and IL-13 levels in the supernatants of H/RS cell lines, an effect that was blocked by soluble RANK. Furthermore, soluble RANK decreased the basal level of IL-8 in one cell line, suggesting that IL-8 was induced by an autocrine RANKL/RANK loop. RANKL had no effect on H/RS cell survival in culture, and it did not modulate the expression of bcl-2, bcl-xL, bax, or inhibitors of apoptosis proteins. These data provide evidence of further functional similarities between DCs and H/RS cells. The coexpression of RANK and RANKL in H/RS cells suggests that they may regulate cytokine and chemokine secretion in H/RS cells by an autocrine mechanism.

Primary hepatic lymphoma: favorable outcome after combination chemotherapy.

BACKGROUND: Primary hepatic non-Hodgkin lymphoma (PHL) is a rare and difficult to diagnose lymphoproliferative disorder of unknown etiology. It is believed that the prognosis in affected patients is dismal, consisting of early recurrence and short survival. METHODS: A retrospective cohort review of patients with PHL diagnosed between 1974 and 1995 at a university cancer center was performed. RESULTS: Twenty-four patients with PHL were identified. Typically, the disease occurred in middle-aged men (median age, 50 years). The primary presenting complaint was right upper quadrant abdominal pain, with hepatomegaly found at physical examination. Serum liver enzymes, lactate dehydrogenase, and beta-2-microglobulin levels all were elevated, but alpha-fetoprotein and carcinoembryonic antigen levels were within normal range. Hypercalcemia was found in 6 of 15 patients who were tested. Six of 10 patients who were tested were positive for the hepatitis C virus (HCV). Liver scans demonstrated either a solitary lesion or multiple lesions. Pathologic examination revealed diffuse large cell lymphoma in 23 patients (96%). Combination chemotherapy was the mainstay of treatment; surgery consisted of diagnostic biopsy. The complete remission rate was 83.3%, and the 5-year cause specific and failure free survival rates were 87.1% and 70.1%, respectively. HCV infection did not appear to influence the outcome of therapy. CONCLUSIONS: The outcome of patients with PHL who are treated with combination chemotherapy may be more favorable than that reported elsewhere. The frequent association of PHL with HCV infection observed in this series warrants further investigation.

Expression of CD26 and its associated dipeptidyl peptidase IV enzyme activity enhances sensitivity to doxorubicin-induced cell cycle arrest at the G(2)/M checkpoint.

CD26, a M(r) 110,000 surface-bound ectopeptidase with dipeptidyl peptidase IV (DPPIV) activity, has an array of diverse functional properties, with a role in T-cell physiology and the development of certain human cancers. In this study, we report that surface expression of CD26, through its associated DPPIV enzyme activity, enhanced sensitivity of Jurkat T-cell transfectants to G(2)-M arrest induced by the chemotherapeutic drug, doxorubicin. This was associated with disruption of cell cycle-related events, including hyperphosphorylation and inhibition of p34(cdc2) kinase activity, phosphorylation of cdc25C, and alteration in cyclin B1 expression. In addition, we demonstrate that the addition of exogenous soluble DPPIV enhanced sensitivity of lymphoid tumor cell lines to doxorubicin, suggesting a potentially useful clinical role for CD26/DPPIV in the treatment of selected human hematological malignancies.

Hematologic recovery after central lymphatic irradiation for patients with stage I-III follicular lymphoma.

BACKGROUND: The authors previously reported that central lymphatic irradiation (CLI) can induce molecular remission in patients with Stage I-III follicular lymphoma, as measured by polymerase chain reaction analysis for t(14;18) (q32;q21). Hematologic toxicity has been considered a major consequence of CLI. This study was undertaken to analyze the patterns of hematologic recovery after CLI. METHODS: Thirty-three patients with Stage I-III follicular lymphoma were treated with CLI between January 1993 and February 1998. CLI consisted of irradiation to mantle, upper two-thirds of abdomen, and pelvic fields. Each field was treated to 30.0-30.6 grays (Gy) at 1.5-1.8 Gy per fraction, with a boost to 36.0-39.6 Gy at the same rate to the sites of macroscopic disease. A break of approximately 4 weeks was given after treatment of each field. Twenty-four patients who were followed for a minimum of 1 year from the end of CLI form the basis of this analysis. Fourteen patients were male. Three patients had Stage I disease, 6 patients had Stage II disease, and 15 patients had Stage III disease. The International Prognostic Index (IPI) for malignant lymphoma was 0 for 5 patients, 1 for 13 patients, and 2 for 6 patients. The Eastern Cooperative Oncology Group performance status was 0 for 21 patients and 1 for 3 patients. The median values for their pretreatment characteristics were as follows: age, 60 years (range, 34-73 years); height, 173 cm (range, 155-193 cm); weight, 79 kg (range, 57-107 kg); body surface area (BSA), 1.95 m(2) (range, 1.61-2.31 m(2)); bone marrow cellularity, 27%(range, 2-75%), platelet count, 233,000/mm(3) (range, 139,000-339,000/mm(3)), white blood cell (WBC) counts, 6400/mm(3) (range, 4200-10,900/mm(3)); and hemoglobin, 14.5 mg/dL (range, 11.8 -16.6 mg/dL). The median duration of CLI was 159 days (range, 137-345 days). Ten patients had cardiovascular disease. The number of sites receiving a boost dose of > or = 36.0 Gy was 0 sites in 1 patient, 1 site in 6 patients, 2 sites in 11 patients, 3 sites in 5 patients, and 4 sites in 1 patient. The platelet, hemoglobin, and WBC counts were followed every 3 months after completion of CLI. These counts were normalized to the pretreatment counts for statistical analyses. Univariate and multivariate analyses were performed to investigate the correlations between patient factors and hematologic status at 1 year posttreatment. Pearson correlation analysis was used for the continuous factors (patient age, height, weight, BSA, bone marrow cellularity, and duration of CLI), and the Mann-Whitney test was used for categoric factors (IPI, gender, performance status, stage, number of sites receiving > or = 36.0 Gy, and presence or absence of cardiovascular disease). RESULTS: There was continued recovery, essentially approaching the pretreatment levels, over 3 years for platelet, WBC, and hemoglobin counts. Factors that were associated significantly with normalized platelet counts at 1 year by univariate analyses were age (P = 0.015) and cardiovascular disease (P = 0.041). Age was the only significant factor by multivariate analyses, with older patients having lower platelet counts at 1 year posttreatment. No factors were found that were associated significantly with 1-year normalized WBC or hemoglobin levels by either univariate or multivariate analyses. CONCLUSIONS: All three of the hematologic components (platelets, WBC, and hemoglobin) essentially recover after patients undergo CLI over a 3-year period. Older age was the only significant adverse factor that affected the platelet recovery, as detected by multivariate analysis. (c) 2001 American Cancer Society.

Treatment of unicentric and multicentric Castleman disease and the role of radiotherapy.

BACKGROUND: Although surgery is considered standard therapy for unicentric Castleman disease, favorable responses to radiotherapy also have been documented. The authors undertook this study to analyze the clinical factors, treatment approaches, and outcomes of patients with unicentric or multicentric Castleman disease, and to report the outcomes of patients with unicentric Castleman disease treated with radiotherapy. METHODS: The authors reviewed the medical records of 22 patients who had received a histologic diagnosis of Castleman disease at the University of Texas M. D. Anderson Cancer Center between 1988 and 1999. One patient with a concurrent histopathologic diagnosis of nonsecretory multiple myeloma was excluded from the study. In all patients, the diagnosis of Castleman disease was based on the results of lymph node biopsies. Disease was categorized as being either unicentric or multicentric and further subdivided into hyaline vascular, plasma cell, or mixed variant histologic types. Clinical variables and outcomes were analyzed according to treatment, which consisted of surgery, chemotherapy, or radiotherapy. RESULTS: Records from 21 patients were analyzed: 12 had unicentric disease, and 9 had multicentric disease. The mean follow-up time for the entire series was 51 months (median, 40 months). Four patients with unicentric disease were treated with radiotherapy alone: 2 remain alive and symptom free, 2 died of causes unrelated to Castleman disease and had no evidence of disease at last follow-up. Eight patients with unicentric disease were treated with complete or partial surgical resection, and all are alive and asymptomatic. All nine patients with multicentric disease were treated with combination chemotherapy: five are alive with no evidence of disease, and four are alive with progressive disease. CONCLUSIONS: Surgery results in excellent rates of cure in patients with unicentric Castleman disease; radiotherapy can also achieve clinical response and cure in selected patients. Multicentric Castleman disease is a more aggressive clinical entity and is most effectively treated with combination chemotherapy, whereas the role of radiotherapy in its treatment remains unclear.

Mantle irradiation alone for pathologic stage I and II Hodgkin's disease: long-term follow-up and patterns of failure.

PURPOSE: We performed a retrospective study to determine the long-term outcome, patterns of failure, and prognostic factors for patients with pathologic Stage I or II Hodgkin's disease (HD) who were treated with mantle irradiation alone. METHODS AND MATERIALS: The medical records of 145 patients with pathologic Stage I or II supradiaphragmatic Hodgkin's disease treated with mantle irradiation alone between June 1967 and June 1991 were reviewed. Patterns of failure, overall survival (OS) rate, and progression-free survival (PFS) rate were determined. Univariate and multivariate analyses were performed to identify adverse prognostic factors for OS and PFS. The number of adverse prognostic factors per patient was counted, and a prognostic score was assigned to each patient. The log-rank test was used to compare the OS or PFS rates among patients with prognostic scores 0, 1, and 2. RESULTS: The median patient age was 27 years (range 10-66), with almost even male to female distribution. Every patient had splenectomy and negative laparotomy (LAP). Fifty-one patients had Stage I disease (IA-49, IB-2) and 94 Stage II (IIA-89, IIB-5). The histologic subtypes were nodular sclerosing in 110, mixed cellularity in 28, lymphocyte predominance in 5, lymphocyte depleted in 1, and unclassified in 1. Twelve patients with Stage II disease had >/= 3 sites of nodal involvement. Fifty-four patients had a prognostic score of 0, 70 of 1, and 21 of 2. The median follow-up time for the 109 surviving patients was 146 months (range 25-381). The 10- and 20-year actuarial OS rates for the whole group were 87.6% and 65.3%, respectively. The corresponding actuarial PFS rates were 75.3% and 74.2%, respectively. Thirty-six patients (9 Stage I, 27 Stage II) had relapses in a total of 41 sites. Failures by histology were 29 patients with nodular sclerosing, 6 with mixed cellularity, and 1 with lymphocyte predominance. Failures by sites were: trans-diaphragmatic, 22 (para-aortic nodes, 15; as the only site of progression in 12; visceral, 7; as the only site of progression in 5); within radiation field, 8; marginal miss, 8 (as the only site of failure in 2); and unknown, 3. The majority of the failures occurred within 5 years of diagnosis. Long-term side effects of radiation included cardiac complications in 30 patients, with 10- and 20-year actuarial cardiac complication rates of 12.6% and 35.1%, respectively; secondary solid tumors in 14, with 10- and 20-year actuarial rates of 2.3% and 25.7%, respectively; leukemia in 4; non- Hodgkin's lymphoma in 4, with the 10- and 20-year actuarial rates for leukemia and non-Hodgkin's lymphoma of 4.0% and 13.9%; and hypothyroidism in 38. Four adverse prognostic factors were identified for PFS: age > or = 40 years, > or = 3 sites of involvement, male sex, and constitutional symptoms. The prognostic score correlated with patients' outcome as indicated by PFS and OS rates. Patients with a prognostic score of 0 did significantly better than those with a score of 1 or 2. CONCLUSION: In this select group of patients with pathologic Stage I and II Hodgkin's disease treated with mantle irradiation alone, the OS and PFS rates at 10 and 20 years were comparable to those reported in the literature. The major pattern of disease progression was relapse below the diaphragm, therefore close surveillance of the abdomen is warranted. The prognostic score used in our series may predict the patient's outcome, and might be worth testing in a prospective trial. In our series, patients with a prognostic score of 0 had excellent long-term survival, indicating adequate treatment with mantle irradiation alone. Late complications of the treatment pose a significant threat for the patient's survival with long-term follow-up.

Bulky disease is an adverse prognostic factor in patients treated with chemotherapy comprised of cyclophosphamide, doxorubicin, vincristine, and prednisone with or without radiotherapy for aggressive lymphoma.

BACKGROUND: In the current study, the authors analyzed prognostic factors in patients with aggressive lymphoma treated with a chemotherapy regimen comprised of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) with or without radiotherapy. METHODS: Between September 1988 and December 1996, 294 patients with newly diagnosed, clinical Ann Arbor Stage I-IV, aggressive lymphoma were enrolled on 2 protocols at The University of Texas M. D. Anderson Cancer Center. Patients on these studies had a relatively favorable prognosis; 100% had M. D. Anderson tumor scores 1 extranodal site of disease (P < 0.001), bulky disease (>or= 7 cm) (P = 0.005), and an at least 10% elevation in the serum lactate dehydrogenase (LDH) level (P = 0.007). Patient age > 60 years (P = 0.001), bulky disease (P = 0.016), and an at least 10% elevation in the serum LDH level (P = 0.040) also were found to be independent prognostic factors for overall survival. CONCLUSIONS: The independent prognostic factors in the current study suggest that either the M. D. Anderson tumor score system or the IPI can be used to select which aggressive lymphoma patients are at high risk for disease recurrence based on their having more than two adverse factors and who consequently are candidates for more intensive frontline therapy. Involved-field radiotherapy should be considered in those patients with bulky lymphomas.

The significance of molecular response of follicular lymphoma to central lymphatic irradiation as measured by polymerase chain reaction for t(14;18)(q32;q21).

BACKGROUND: More than 80% of the patients with follicular lymphoma have a characteristic chromosomal translocation, t(14;18)(q32;q21), at the major breakpoint region (MBR) or minor cluster region (MCR) involving the bcl-2 oncogene. This study was undertaken to assess the significance of the molecular response rate measured by the polymerase chain reaction (PCR) evidence of translocation among patients with Stage I to III follicular lymphoma treated with central lymphatic irradiation (CLI). METHODS AND MATERIALS: Thirty-three patients with Stage I-III follicular lymphoma were treated with CLI on a prospective protocol. Bone marrow and peripheral blood samples were obtained before CLI for PCR analysis of t(14;18)(q32; q21). PCR-positive patients were followed by PCR analysis at regular intervals during and after CLI, and the results were correlated with clinical outcome. The following pretreatment factors were also investigated for their relationship to relapse and molecular response: gender, age, lactate dehydrogenase (LDH) and beta-2 microglobulin (beta2M) levels, Ann Arbor stage, and International Prognostic Index (IPI) for malignant lymphoma. RESULTS: The subjects were 19 men and 14 women, with a median age of 52 years (range 30-69), who started CLI between January 1993 and February 1998. Median follow-up was 44 months (range 12-67), and all but 2 patients were still alive at the last follow-up. Four patients were Stage IA, 8 were Stage IIA, 19 were Stage IIIA, and 2 were Stage IIIB. Two patients had abnormal LDH levels (> 618 U/dL) and 7 patients had abnormal beta2M levels (> 2 mg/dL). Nine patients had IPI = 0, 16 had IPI = 1, and 8 had IPI = 2. All patients achieved complete response (CR). Twelve patients have relapsed to date. The median overall time to relapse was 54 months. The actuarial proportion of patients free from relapse at 3 years was 87% (95% confidence interval [CI] 69-95%). A total of 287 PCR results were available, 64 from bone marrow and 223 from peripheral blood. Pretreatment PCR data were available for 27 patients, of whom 21 were positive and 3 were unambiguously negative (in blood and bone marrow for both MBR and MCR). For the 19 PCR positive patients for whom we had post-treatment results, there was a clear and steady decreasing trend toward loss of PCR positivity (49% positive for bone marrow and 32% positive for peripheral blood at 3 years). There was a clear trend for increasing PCR positivity with increasing IPI: 10% for IPI = 0, 31% for IPI = 1, and 63% for IPI = 2 at 3 years for blood. The same trend was also observed for bone marrow. The IPI was the only statistically significant predictor for relapse with a relapse-free survival of 91% at 3 years for IPI < 2 and 75% for IPI = 2 (p = 0.024, log-rank test). CONCLUSION: Molecular response to CLI occurs gradually over years. High IPI is a negative predictor for molecular response and relapse-free survival.
