Abstract
PURPOSE The CD20 antigen is expressed on more than 90% of B-cell lymphomas. It is appealing for targeted therapy, because it does not shed or modulate. A chimeric monoclonal antibody more effectively mediates host effector functions and is itself less immunogenic than are murine antibodies. PATIENTS AND METHODS This was a multiinstitutional trial of the chimeric anti-CD20 antibody, IDEC-C2B8. Patients with relapsed low grade or follicular lymphoma received an outpatient treatment course of IDEC-C2B8 375 mg/m2 intravenously weekly for four doses. RESULTS From 31 centers, 166 patients were entered. Of this intent-to-treat group, 48% responded. With a median follow-up duration of 11.8 months, the projected median time to progression for responders is 13.0 months. Serum antibody levels were sustained longer after the fourth infusion than after the first, and were higher in responders and in patients with lower tumor burden. The majority of adverse events occurred during the first infusion and were grade 1 or 2; fever and chills were the most common events. Only 12% of patients had grade 3 and 3% grade 4 toxicities. A human antichimeric antibody was detected in only one patient. CONCLUSION The response rate of 48% with IDEC-C2B8 is comparable to results with single-agent cytotoxic chemotherapy. Toxicity was mild. Attention needs to be paid to the rate of antibody infusion, with titration according to toxicity. Further investigation of this agent is warranted, including its use in conjunction with standard chemotherapy.

Abstract
Abstract
Background: Achieving a pathologic complete response (pCR) after neoadjuvant chemotherapy (NAC) has been associated with improved disease free survival (DFS) and overall survival (OS). The Residual Cancer Burden Score (RCB) method is a useful tool that predicts DFS and OS after NAC. We present the results of pts with either triple negative or HER2 positive breast cancer treated with a novel NAC. Methods: 34 pts with localized breast cancer >1 cm with HER2+ (N = 19) or triple negative breast cancer (TNBC) (N = 15) were treated with this novel regimen consisting first of TEC (docetaxel 75 mg/m2, epirubicin 80 mg/m2, and cyclophosphamide 500 mg/m2) + PEG Filgrastim x 4 cycles. Following the 4th course, TNBC patients received 4 additional TEC cycles if they achieved CR by MRI, or were switched to a non cross-resistant regimen (vinorelbine, bevacizumab, capecitabine) if they had < CR. HER2+ pts received TEC x4 followed by docetaxel + trastuzumab x 4. RCB score was used to measure pathologic response. Pretreament PET scan was done and repeated after course 1 in order to correlate with RCB. Results: Median age was 56 (58 for Her2+ and 49 for TNBC). RCB = 0 (pCR) was achieved in 76%, while only 1 responded poorly (RCB = 3). There was no significant difference in the pCR rate between Her2+ and TNBC patients (74% vs 80% respectively), but there was a difference in the rate of pCR without DCIS and invasive cancer between these two (see table, p = 0.034). Pts with SUV drop > 5% after 1st TEC had 84% pCR while none with < 5% achieved pCR (p = 0.001). Comparison of our results with other NAC regimens reported in the literature is summarized in the table below:

Conclusions: This novel chemotherapy approach results in a high pCR rate and RCB 0-1, which have been associated with improved clinical outcomes. Early PET can predict pCR. Although sample size is modest, results are encouraging and deserve further evaluation.

Abstract
The purpose of the study was to evaluate the safety, efficacy, and pharmacokinetics of pixantrone (BBR2778) when substituted for etoposide in the ESHAP regimen in patients with aggressive relapsed or refractory non-Hodgkin's lymphoma. Nineteen patients received protocol therapy, consisting of pixantrone 80 mg/m2 over 1 h on day 1, methylprednisolone 500 mg on days 1 - 5, cisplatin 25 mg/m2 on days 1 - 4, and cytarabine 2000 mg/m2 on day 5. Cycles were repeated every 21 days, in the outpatient setting. Dose limiting toxicity, consisting of bone marrow suppression, occurred at the first dose level (80 mg/m2), which was defined as the recommended dose. Grade 3 and 4 toxicities were mainly hematologic. Only one patient had grade 4 febrile neutropenia. No significant decreases in ejection fraction greater than 20% occurred. Overall response rate was 58%, with 37% complete and 21% partial responses. Six of the 11 responders (55%) underwent stem cell transplant. Median time to progression and overall median survival were 5.7 months and 14.5 months, respectively. There is no significant interaction between pixantrone and the combined drugs. The recommended dose of pixantrone in combination with methylprednisolone, cytarabine, and cisplatin (PSHAP) is 80 mg/m2. PSHAP is an active salvage regimen and should be further evaluated as a pretransplant cytoreductive regimen.

Abstract
18501 Background: Therapy for aggressive B cell NHL includes CHOP-rituximab (CHOP-R)q 14 days with G-CSF support. We are now investigating CHOP-R plus pegfilgrastim (Neulasta [N]) and low dose GM-CSF (Leukine). The rationale for low dose GM-CSF is based on its stimulation of ADCC which appears to be the most important mechanism of action of R and upregulation of CD20 on B cells, in addition, to other immunomodulating effects. Some of these are seen at lower levels of GM-CSF and appear to be lost at higher doses. N is given in order to allow delivery of chemotherapy q. 2 weeks. Methods: The goal was to determine the optimal dose of GM-CSF needed to support absolute neutrophil count (ANC) recovery >1,000 by day 14 without inducing marked leucocytosis when combined with N. R is given on day 1, CHOP on day 2 and growth factors start on day 3. We used a single fixed low dose of N 3 mg s.c. on day 3 and an escalating dose of GM-CSF starting at 75 mcg s.c. on day 3. GM-CSF was repeated every Monday, Wednesday and Friday. Results: So far we have delivered 65 evaluable courses to 18 pts (16 evaluable) whose median age was 58 (range 26–87). The plan was to escalate GM-CSF as necessary to support ANC recovery by day 14 without inducing severe leucocytosis. GM-CSF was to be escalated in cohorts of 5 patients at: 75, 125 and 250 mcg. The first cohort of 5 was treated at 75 mcg and all 5 recovered their ANC to >1,000 by day 14 and none exceeded ANC >50,000 before day 14. Therefore the next cohort of 5 received the same dose of 75 and all 5 were able to recover by day 14. Subsequently the next 6 were also treated at the same dose of 75 mcg. During 65 total courses, all but 3 pts recovered ANC to >1,000 before day 14. Chemotherapy doses were not reduced unless severe infection (i.e. septic shock or bilateral pneumonia). Because of prolonged or severe neutropenia, intrapatient dose escalations of GM-CSF were done in 2 pts (to 125 mcg) during the 2nd course and to 250 mcg in 1 pt during the 3rd. Conclusions: GM- CSF 75 mcg on Mondays, Wednesdays and Fridays is adequate and safe to support ANC recovery if combined with 3 mg N. However, in view of encouraging data of McLaughlin et al with 250 mcg of Leukine plus R in indolent NHL, in the next study we will attempt to escalate Leukine to 250 mcg. [Table: see text]

Predictive value for survival of a risk model of two serological markers, beta-2-microglobulin (B2M) and lactic dehydrogenase (LDH), in diffuse large cell lymphoma (DLCL). J Clin Oncol 2007.

Abstract
10599 Background: The International Prognostic Index (IPI), the standard tumor risk model in patients (pts) with diffuse large cell lymphoma (DLCL), has 5 factors (age, LDH, performance status, extra nodal sites, and stage). We previously proposed a simpler two-factor model, based on LDH and B2M (JCO10;1989). B2M is a component of HLA class I antigens, expressed in lymphocytes, and a known prognostic indicator in some lymphoid malignancies. The benefits of this model are: objective measures; lab method widely available; simplicity; biologic marker. Methods: We applied the model to a large cohort of DLCL patients with prospective baseline B2M, and treated with doxorubicin-based (chemo) regimens, with and without rituximab. 718 pts with DLCL were sequentially treated at MDACC by IRB approved chemo protocols from 1988–2000. In 2001, rituximab plus chemo (RCHOP) became standard. 311 DLCL pts were sequentially treated with RCHOP from 2001–2005. Cox regression analyses for univariate and multivariate models of IPI factors and B2M were done. Kaplan-Meier survival projections were in three risk categories: low (normal [nl] LDH and B2M); intermediate (either LDH or B2M > nl); or high (LDH and B2M > nl). Results: In both treatment groups, IPI factors and B2M were significant as univariate factors. In the RCHOP group, however, the IPI multivariate model showed age, stage, and extra-nodal sites were not significant risk factors, while B2M and LDH remained highly significant (p<0.01). The 5 year survival projections by risk category were: (*) combines intermediate low and intermediate-high categories Conclusions: This simple two-factor model predicts risk for patients with DLCL, treated with or without rituximab, comparably to the IPI. B2M should be considered an important prognostic indicator in DLCL, particularly in rituximab treated patients. Exploratory analyses to revise the IPI model are indicated.

Abstract
8058 Background: R-HCVAD (rituximab-cyclphosphamide, vincristine, dexamethasone, doxorubicin) alternating with R-MTX-ARAC (rituximab, methotrexate-cytarabine) is a chemoimmunotherapy regimen with activity in ALL, mantle cell, and Burkitt’s lymphomas (BL). Histological differentiation between BL, atypical BL, and DLBCL with high-grade features can be difficult. We thus have treated patients with DLBCL with high-grade histological features and/or poor-risk IPI with R-HCVAD. Methods: Forty consecutive patients with information collected prospectively in the NCCN database, treated between 7/2002 and 10/05 at M.D Anderson Cancer Center, and who received at least one cycle are included in this cohort analysis. Characteristics: 18 (45%) male; 18 (45%) HI and High IPI; 25 (62.5%) ↑LDH; 26 (65%) with Stage III/IV; 2 (5%) with PS>1; 8 (20%) with >60 years; 25 (62%) a Ki-67 >90%. Four patients received less than 4 cycles of treatment. Results: ORR was of 100%, with 95% CR/CRu. With a median follow-up of 26 months, 6 patients failed: 1 died in CR of pulmonary embolism while on treatment; 1 patient who achieved CR, had PD before the end of treatment; 1 achieved a PR and was transplanted (is alive in remission); 1 achieved a PR and progressed died of disease; and 2 relapsed (one is in remission after an ASCT). Four patients have died: 3 of disease, 1 of pulmonary embolism. The 3-year OS is 88% (95% CI 77%-99%); 3-year FFS is 71% (95% CI 47%-95%). The 3-year FFS for patients with L/LI risk (3-failures of 22 pts) was 78% (95% CI 52%-100%); and for patients with HI/H IPI (3 failures of 18 pts) 65% (95% CI 27%-100%). Conclusions: R-HCVAD/R-MTC-ARAC is a very active regimen for DLBCL of high grade. Toxicity was mostly hematological. We are currently doing a prospective randomized phase II study comparing this regimen to standard R-CHOP in patients with poor-risk IPI scores. No significant financial relationships to disclose.

Abstract
BACKGROUND Rituximab is associated with low incidence of hypogammaglobulinemia and little morbidity. Our experience with the combination of rituximab + chemotherapy suggested the opposite. PATIENTS AND METHODS We analyzed our experience with rituximab plus chemotherapy in 97 patients to determine: frequency and type of non-neutropenic infection (NNI); frequency and type of hypogammaglobulinemia; response to gammaglobulin therapy; and factors associated with NNI. RESULTS We observed 40 episodes of NNI in 19 of 97 (20%) patients. By 3 years, 43% of patients treated with rituximab + chemotherapy were projected to have developed at least one NNI. Of 19 with NNI, 15 had Ig levels studied and all 15 had hypogammaglobulinemia. Most frequently affected Ig were IgG (14 of 15) and IgM (13 of 14). IgA was usually spared (six of 14 cases affected). NNIs observed were 18 bronchitis, 16 sinusitis, four pneumonias, three otitis media, two fevers of unknown origin (FUOs) and three herpes zoster. Hospitalization was required in seven of 19. Ten received gammaglobulin infusions and all responded promptly. Gammaglobulin was given only when NNIs recurred. We examined sex, age, histology, type of rituximab-chemotherapy (fludarabine + rituximab versus other chemotherapy + rituximab) for correlation with NNI. CONCLUSIONS Indolent histology, female sex and fludarabine + rituximab significantly correlated with frequency of NNI but multivariate analysis picked fludarabine + rituximab followed by female gender as the only two independent variables predictive of NNI.

Abstract
17513 High dose chemo/autologous stem cell transplant (ASCT) is standard treatment for relapsed aggressive NHL. However many are unable to receive ASCT because they are refractory to salvage therapy, too old or too sick. More effective, less toxic salvage regimens are needed prior to ASCT. Gemcitabine (G) and Oxaliplatin (O) are active agents in NHL and exhibit synergism so their combination is attractive to explore together with Rituximab (R). We hereby report the results of a phase I-II trial designed to explore the GROC regimen administered every 14 days with Pegfilgrastim support. After the first 6 pts were entered, the phase I portion was completed; recommended dose: R = 375 mg/m2 on day 1, G = 1,250 mg/M2 on day 2, O = 100 mg/m2 on day 2 and Neulasta 6 mg day 3. So far we have entered 21 pts of which 19 are currently evaluable. Median age = 58 (range = 27–88); 9 were refractory to 1st line therapy, 5 were on 1st relapse, 3 on 2nd and 2 >2 relapses, 12 had high LDH, 10 high Beta-2-M. Using IWG/PET criteria ORR = 79%, CR = 42%, PR = 37%. There was a correlation between response to preceding chemo regimen and response to GROC ( table ). In 6 the response to GROC was better than to preceding regimen while only in 2 was the response worse. At 1 year the projected OS is 49% and PFS 34%. So far, only 5 of 15 responders have relapsed. An intriguing finding is that in 6 of 15 responders, PFS has been longer with GROC than with preceding regimen and shorter in only 1. Grade 4 hematologic toxicity occurred only once. No neutropenic fevers seen. Most common toxicity was reversible transaminitis in 13 (grade 1–2 in 10, grade 3 in 3), neuropathy in 9 (grade 1–2 in 8, grade 3 in 1), diarrhea in 3 (grade 4 in 1). We could deliver courses at a median interval of 14 days. Conclusions: 1- GROC is an effective dose dense salvage regimen. 2- It appears effective even in pts with poor prognostic features including primary refractory disease. 3-Hematologic toxicity is very low and non-hematologic toxicity acceptable.

Abstract
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.

Abstract
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%.

Abstract
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.

Abstract
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.

Abstract
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.

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. Ann Oncol 2002; 13:1290-9.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

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. Cancer Res 2001; 61:7204-10.

Abstract
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.

Abstract
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.

Anaplastic lymphoma kinase (ALK) is not expressed in Hodgkin's disease: results with ALK-11 antibody in 327 untreated patients. Leuk Lymphoma 2001; 42:969-79.

Abstract
The t(2;5)(p23;q35) or other rare chromosomal abnormalities involving 2p23 upregulate the ALK gene, which is not expressed in normal lymphocytes. Thus, detection of ALK protein is presumptive evidence of these 2p23 abnormalities. The t(2;5) and ALK immunoreactivity are common in anaplastic large cell lymphoma of T/null-cell lineage. However, a small subset of cases of Hodgkin's disease (HD) have been reported to either carry the t(2;5) or express ALK. In this study, we have immunohistochemically evaluated 327 cases of HD with the ALK-11 antibody. ALK-11 is a well characterized polyclonal antibody raised against an intracellular portion of the ALK protein. We detected ALK-11 immunoreactivity in 8 (2.4%) cases of HD. We further studied these positive cases with ALK-1 monoclonal antibody, which reacts with an intracellular portion of ALK, similar to ALK-11. All 8 ALK-11 positive cases were negative for ALK-1. These results indicate that rare cases of HD may react with ALK-11 antibody, similar to previous reports by others using different polyclonal anti-ALK antibodies. However, the absence of ALK-1 expression in these HD cases suggests that ALK protein is not truly present and that polyclonal anti-ALK antibodies may rarely yield non-specific cross reactivity. These results further support the use of anti-ALK antibodies in the differential diagnosis of HD from ALCL.

Abstract
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.

Abstract
Anaplastic large-cell lymphoma (ALCL) of T- or null-cell lineage, as defined in the revised European-American lymphoma classification, includes a subset of tumors that carry the t(2;5)(p23;q35) resulting in overexpression of anaplastic lymphoma kinase (ALK). Patients with ALK+ ALCL are reported to have a better prognosis than patients with ALK- ALCL. Because the mechanisms for this survival difference are unknown, we investigated the hypothesis that apoptotic pathways may be involved. We therefore assessed expression levels of the anti-apoptotic proteins BCL-2 and BCL-XL and the pro-apoptotic proteins BAX and BCL-XS in T/null-cell ALCL using immunohistochemical methods and correlated the findings with ALK expression and apoptotic rate (AR), the latter assessed by a modified Tdt-mediated dUTP nick-end labeling assay. ALK was detected in 21 of 66 (31.8%) ALCLs. BCL-2 was not detected in 21 ALK+ ALCLs but was present in 26 of 45 (57.8%) ALK- ALCLs (P < 0.0001). ALK+ and ALK- ALCLs also showed significant differences in expression of BCL-XL, BAX, and BCL-XS. ALK+ tumors less commonly had a high level of BCL-XL (1 of 17 versus 14 of 35, P = 0.01), and more commonly had high levels of BAX (13 of 18 versus 15 of 36, P = 0.05), and BCL-XS (11 of 16 versus 12 of 31, P = 0.05) compared with ALK- tumors. ALK+ tumors also had a higher mean AR than ALK- tumors (3.4% versus 1.1%, P = 0.0002). Differential expression of BCL-2 family proteins may be responsible for the higher AR observed in ALK+ ALCL and provides a possible biological explanation for the better prognosis reported for patients with ALK+ ALCL.

Mantle irradiation alone for pathologic stage I and II Hodgkin's disease: long-term follow-up and patterns of failure. Int J Radiat Oncol Biol Phys 2001; 50:971-7. [PMID: 11429225 DOI: 10.1016/s0360-3016(01)01525-5] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/25/2022]
Abstract
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.

Abstract
BACKGROUND Used as single agents, paclitaxel and topotecan have demonstrated promising activity in treating patients with relapsed aggressive non-Hodgkin's lymphoma (NHL). We conducted a phase II clinical trial to investigate the activity and tolerability of the combination of both drugs. PATIENTS AND METHODS Patients with refractory or relapsed aggressive NHL who had previously been treated with a maximum of two prior chemotherapeutic regimens were given intravenous infusions of paclitaxel 200 mg/m2 over three hours on day one and topotecan 1 mg/m2 over 30 minutes daily from days one to five. All patients received daily subcutaneous injections of filgrastim (granulocyte colony-stimulating factor) 5 microg/kg starting 24 hours after the last dose of chemotherapy until neutrophil recovery. Treatments were repeated every three weeks for a maximum of six courses. Patients who achieved partial remission or complete remission (CR) after at least two courses were offered stem cell transplantation, if eligible. RESULTS Of the 71 patients eligible for this trial, 66 (93%) were evaluable for treatment response. The median age was 53 years (range 23 to 74 years). Thirty-six percent of the patients had previously been treated with ara-C/platinum-based regimens, and 48% failed to achieve CR after primary induction therapy. Sixty-seven percent of the patients had elevated lactate dehydrogenase levels at the time of treatment initiation. The overall response rate was 48% (95% confidence interval (95% CI): 36%-61%). Patients who had primary refractory disease had a response rate of 31%, compared with 65% for patients who did not. Similarly, the response rate of patients who failed to achieve CR after their most recent previous therapy was 37%, compared with a 65% response rate in patients who relapsed from a first or second CR. The median duration of response was six months. A total of 199 courses were given, with a median of three courses per patient. Neutropenia at levels < or = 500 leukocytes per microliter was observed after 32% of the courses, and thrombocytopenia at levels < or = 20,000 platelets per microliter was observed after 17% of the courses. Grade 3-4 neutropenic fever occurred after 6% of the courses. Non-hematologic toxic effects were predominantly grade 1-2. CONCLUSION The combination of paclitaxel and topotecan is an effective first or second line salvage therapy for patients with relapsed or refractory aggressive NHL who had prior anthracycline- or platinum-based chemotherapy.

Irinotecan in relapsed or refractory non-Hodgkin's lymphoma. ONCOLOGY (WILLISTON PARK, N.Y.) 2001; 15:53-6. [PMID: 11497233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Subscribe] [Scholar Register] [Indexed: 02/21/2023]
Abstract
Irinotecan (CPT-11, Camptosar) is a topoisomerase I inhibitor with a broad spectrum of antitumor clinical activity. Various schedules and doses have been studied, and major complications were delayed diarrhea and myelosuppression. We explored the activity of irinotecan in patients with relapsed or refractory non-Hodgkin's lymphoma, using a 3-week schedule of administration. Eligible patients had histologically proven relapse, had received no more than two previous regimens, were > or = 15 years and < or = 75 years old, had normal renal function, neutrophil count > 1,500/microL, platelet count > 100,000/microL, and no human immunodeficiency virus infection or central nervous system involvement. Patients were treated with irinotecan 300 mg/m2 i.v. every 21 days with intensive loperamide management of diarrhea. Responders received up to six treatment cycles. Of 25 patients registered so far, 22 are evaluable for response. The median age was 67 years (range: 25 to 74 years) and 11 were male. The median number of previous regimens was 2 (range: 1 to 4 regimens), and 16 patients had disease that was refractory to their last regimen. Serum lactate dehydrogenase level was high in 75%, and beta2-microglobulin was > 3.0 mg/L in 26% of patients. Responses were seen in 8 of 22 (36%) patients with non-Hodgkin's lymphoma. Response rates were 40% for indolent, 0% for mantle cell, 45% for relapsed aggressive, and 33% for refractory aggressive lymphomas. Grade 3/4 toxicities included myelosuppression, neutropenic fever, and delayed diarrhea. Irinotecan appears active and relatively well tolerated in patients with relapsed aggressive non-Hodgkin's lymphoma. Accrual to this study is continuing for better determination of the response rate in all histologic subtypes of non-Hodgkin's lymphoma.

Abstract
CD26 is a M(r) 110,000 surface glycoprotein with diverse functional properties, including having a potentially significant role in tumor development, and antibodies to CD26 mediate pleomorphic cellular functions. In this report, we show that binding of soluble anti-CD26 monoclonal Ab 1F7 inhibits the growth of the human CD30+ anaplastic large cell T-cell lymphoma cell line Karpas 299 in both in vitro and in vivo experiments. In vitro experiments show that 1F7 induces cell cycle arrest at the G1-S checkpoint, associated with enhanced p21 expression that is dependent on de novo protein synthesis. Furthermore, experiments with a severe combined immunodeficient mouse tumor model demonstrate that 1F7 treatment significantly enhances survival of tumor-bearing mice by inhibiting tumor formation. Our data therefore suggest that anti-CD26 treatment may have potential clinical use for CD26+ hematological malignancies.

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.

Abstract
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 <or= 2 and 95%% had International Prognostic Indices (IPIs) <or= 2. Treatment was comprised of 5 +/- 1 (mean +/- the standard deviation) cycles of CHOP chemotherapy with or without involved-field radiotherapy to a total dose of 40.1 +/- 3.3 grays (mean +/- the standard deviation). RESULTS The median length of follow-up was 61 months. Three factors were found to retain independent prognostic significance on multivariate analysis in terms of progression-free survival: > 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.
