Prognostic factors, including clinical, biological, and histological parameters, were assessed for 94 patients with follicular lymphomas at our institute. Follicular lymphomas constituted 7.7% (94/1208) of malignant lymphomas in this study. Eighteen patients were diagnosed with stage I follicular lymphoma, 20 with stage II, 23 with stage III, and 33 with stage IV. The cases of follicular lymphoma were subclassified as: follicular small cleaved cell lymphoma (FSC) in 20 cases, follicular mixed cell lymphoma (FMX) in 59 cases, and follicular large cell lymphoma (FLC) in 15 cases. The patients comprised 49 men and 45 women with a median age of 54 years (range, 25-84 years). The complete response rate was 76.5%, and the median survival time was 13 years. The expected 10-year overall survival and event-free survival rates were 61.9% and 38.2%, respectively. Univariate analysis identified the factors associated with poor survival as elevated serum lactate dehydrogenase (LDH) level (P < .0001), age of >60 (P < .0001), Ann Arbor stage III/IV (P < .01), and Eastern Cooperative Oncology Group performance status (PS) of 2 to 4 (P = .048). Multivariate analysis showed that LDH, age, and PS were independent predictors. After application of the International Prognostic Index (IPI), the 10-year survival rates for the low-risk, low-intermediate risk, high-intermediate risk and high-risk groups were 80.4%, 48.7%, 21.9%, and 0.0%, respectively. The differences among these groups were significant at P < .01. The IPI for aggressive non-Hodgkin's lymphoma was found to be applicable to survival prediction for Japanese follicular lymphoma patients.

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.

The prognostic significance of 20 putative markers has been assessed in a consecutive series of 1,198 patients with malignant lymphoma seen by the Sheffield Lymphoma Group over three decades. Univariate analysis disclosed that ten factors for both Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL) Grade I, and twelve factors for NHL Grade II had prognostic significance. However, multivariate analysis selected only three (age, serum albumin and lymphocyte count) for HD, one (serum albumin) for NHL Grade I and five (age, stage, erythrocyte sedimentation rate, serum albumin and serum lactate dehydrogenase) for NHL Grade II as independent predictors for survival. Risk adjusted prognostic models were derived for Hodgkin's disease and NHL Grade II. For Hodgkin's disease the presence of 3 risk factors predicted for only 35% long-term survival for this group of patients. For NHL Grade II the group with 3-5 risk factors present had a median survival of less than 2 years compared to a 9-year median survival in patients with 1 risk factor present. Whilst these models are being validated on a larger series of patients and will also be tested prospectively, new markers are needed to facilitate decisions on treatment for individual patients.

We herein present the findings of a 10-year-old boy with non-Hodgkin's lymphoma of the ascending colon which caused intussusception and intestinal bleeding. He had a history of Becker muscular dystrophy. However, he had neither hypertrophic calves nor cardiomyopathy, and his serum creatine kinase (CK) level always exceeded 2000 IU/l. Preoperatively, a laboratory examination revealed high serum levels of CK (2038IU/l), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH), and the blood hemoglobin level was 7.0g/dl. A barium enema examination revealed an intussusception in his ascending colon, which was found to be a highly vascular tumor on Doppler ultrasound scans. A right hemicolectomy was performed. Macroscopically, the 5 x 6 x 8-cm solid tumor of the ascending colon resembled a submucosal tumor and had two ulcerous lesions at the tip. The tumor was histologically diagnosed to be a diffuse large B-cell lymphoma of the ascending colon. General examinations revealed no involvement of lymphoma postoperatively. At 13 months after surgery, the CK (37861U/l), AST (110lU/l), ALT (1381U/ l), and LDH (420lU/l) levels are still high, and the patient is doing well without any signs of recurrence.

Post-treatment surveillance in non-Hodgkin's lymphoma is required for an early diagnosis of a relapse and for the detection of a potential late treatment-related complication. The risk of relapse is highest during the first 2 years in aggressive lymphomas. The risk of relapse decreases then and becomes very low after the 5th year of follow-up. For low-grade lymphomas, the relapse rate remains constant for a longer period and late relapses are more common. Clinical examination and biological tests (blood cell count, lactate dehydrogenase and, in some instance, beta-2-microglobulin serum level determination) are the basis of the surveillance. Radiological and specific tests will be done according to the initial organ involvement. The frequency of the surveillance mainly depends on the histological subtype. Late chemotherapy-related complications include second cancer (solid tumor, myelodysplastic syndrome and acute leukemia), cardiac and endocrine toxicity. Detection of these events also requires close clinical and biological monitoring.

Death during the induction phase of chemotherapy remains a common event in patients with aggressive non-Hodgkin's lymphoma (NHL). In a series of patients with aggressive NHL homogeneously treated with intensive induction chemotherapy [ACVB (doxorubicin, cyclophosphamide, vindesine, bleomycin, prednisone) regimen], we determined the clinical and biological parameters that were predictive of early death. Early death was defined as death, for whatever reason, occurring within 100 d of randomization. Predictive factors were identified by logistic regression and an index predictive for individual risk of early death was designed. Among the 2210 patients treated with ACVB, there were 162 (7.3%) early deaths. There was no significant reduction in the rate of early death between 1987 and 1998. In a multivariate analysis, age > 60 years, Eastern Cooperative Oncology Group performance status > 1, serum lactate dehydrogenase > normal, serum albumin < 30 g/l, leucocyte counts > 10 x 10(9)/l and haemoglobin levels < 8.5 g/dl were found to be independent predictive factors for early death. An early death index was designed, enabling the evaluation of the individual risk of early death in young (range 2-31% risk of early death) and elderly patients (range 5-53%). Clinical and biological parameters available at diagnosis can help physicians identify patients with aggressive lymphoma at low or high risk of early death.

Strategies for identifying patients at high risk of chemotherapy-induced neutropenia are reviewed. Among lung cancer patients, a 24% rate of neutropenia has been reported. This rate is below the 40% threshold recommended by the American Society of Clinical Oncology (ASCO) for the prophylactic use of colony-stimulating factors. Risk factors for febrile neutropenia in patients receiving adjuvant chemotherapy for breast cancer include older age, fluorouracil-containing regimens, bone marrow involvement or prior myelosuppressive therapy, and concomitant or prior radiation therapy. According to the Silber predictive model, factors suggesting a high risk of hospitalization for febrile neutropenia include the absolute neutrophil count during the neutrophil nadir in cycle 1 of chemotherapy. Patients with non-Hodgkin's lymphoma (NHL) are at risk of febrile neutropenia and fall on the edge of the ASCO guidelines. Risk factors in NHL patients include certain combination chemotherapy regimens, an albumin concentration of > 3.5 g/dL, an above-normal lactate dehydrogenase concentration, bone marrow involvement, age of > 65 years, and renal disease. Patients can be stratified into low-risk and high-risk categories for febrile neutropenia. High risk is associated with a duration of neutropenia of more than seven days and concomitant medical conditions, such as hypotension and diarrhea. A majority of low-risk patients can be managed as outpatients. Prophylactic use of colony-stimulating factors is currently believed not to be cost-effective if the frequency of febrile neutropenia is less than about 20% for a given treatment regimen. Patients at higher risk of febrile neutropenia in association with cancer chemotherapy may include the elderly and those with specific malignancies and prior neutropenic events, as well as those receiving combination chemotherapy and radiation therapy.

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.

Cytokines play important roles in the pathogenesis of lymphomas. The aim of this study was to determine the relations between serum levels of interleukin-2 (IL-2), IL-6, and IL-10 and parameters of International Prognostic Index (IPI). Serum levels of IL-2, IL-6, and IL-10 were measured using a sensitive enzyme-linked immunosorbent assay in the pretreatment frozen sera from 43 patients with non-Hodgkin's lymphoma. The patients we included in the study were divided into two groups, one with high risk and the other with low risk according to the IPI in regard to their ages, stages, performance status, extranodal involvements, and serum levels of lactate dehydrogenase. In the high-risk group, serum levels of IL-2 (0.852 +/- 0.268 ng/ml), IL-6 (0.461 +/- 0.206 ng/ml), and IL-10 (0.816 +/- 0.240 ng/ml) were found to be higher than serum levels of IL-2 (0.667 +/- 0.170 ng/ml), IL-6 (0.355 +/- 0.075 ng/ml), and IL-10 (0.643+0.177 ng/ml) in the low-risk group ( < 0.05). There was a correlation between the patients with high risk according to the IPI criteria and high levels of serum cytokines (IL-2, IL-6, IL-10). Knowledge of the serum levels of these cytokines in patients with newly diagnosed aggressive non-Hodgkin's lymphoma may help us to have some information about the possible prognosis, the activation of disease, and to decide on appropriate therapeutic approaches for individual patients.

We reviewed the clinical characteristics, treatment, and outcome of 67 children with localized and 212 with disseminated large-cell lymphoma (LCL) treated during a 20-year period in 5 consecutive Children's Cancer Group (CCG) non-Hodgkin's lymphoma (NHL) trials. Clinical outcomes for patients treated on the four earlier studies with moderate-dose chemotherapy administered over 12-18 months were compared with patients treated most recently with short, intensive therapy. Median age at diagnosis was 12 years (range: 0-19 years). Male to female ratio was 1.8:1.0. Five-year event-free survival (EFS) was 92% +/- 3.3% and 50 +/- 3.5% for patients with localized LCL and disseminated LCL, respectively. After adjustment for lactate dehydrogenase (LDH), age at diagnosis, and BM involvement, short and intensive therapy as delivered on the most recent study, CCG-5911, was associated with an improved outcome (P< 0.05) compared to the four previous studies. Elevated LDH (> or = 500 IU/L) at diagnosis and young age (<5 years) were both significant independent predictors of poorer long-term EFS (P< 0.05). Long-term survival after relapse or other treatment failure was only 31% +/- 4.7%. In summary, more recent shorter and intense therapy appears to be associated with superior event-free survival for children and adolescents with disseminated LCL. Large numbers of patients treated with shorter and intense therapy are required to confirm these preliminary observations.
