Fludarabine, cyclophosphamide, and dexamethasone (FluCyD) combination is effective in pretreated low-grade non-Hodgkin's lymphoma.

PURPOSE: Fludarabine phosphate is effective as a single agent in low-grade non-Hodgkin's lymphoma (NHL). Combined with other antineoplastic agents it enhances the antitumor effect. Our aim was to define the therapeutic efficacy and toxicity of a combination of fludarabine, cyclophosphamide and dexamethasone (FluCyD) in patients with advanced low-grade lymphoma. PATIENTS AND METHODS: Twenty-five adults with pretreated advanced-stage low-grade NHL were treated with three-day courses of fludarabine 25 mg/m2/day, cyclophosphamide 350 mg/m2/day, and dexamethasone 20 mg/day, every four weeks for a maximum of six courses. RESULTS: Of the 25 patients, 18 (72%) responded, 8 (32%) achieving CR and 10 (40%) PR. Seven were failures. The median follow-up was 21 months (5-26). Eight CR patients remain in CR after 5-21 months. Of 10 PR patients, 3 are in continuous PR without further treatment after 12, 17 and 18 months. Myelosuppression was the most prevalent toxic effect. Although severe granulocytopenia (granulocyte count nadir < 500/microliter) and thrombocytopenia (platelet count nadir < 50,000/microliter) occurred in only 10% and 16% of courses, respectively, slow granulocyte or platelet count recovery caused delay of 40% of the courses. Nine patients (36%) required discontinuation of therapy because of persistent granulocytopenia and/or thrombocytopenia: three after one course, three after 2-4 courses, and three after five courses. Thirteen infectious episodes in 11 patients complicated 11% of courses. Two of 10 patients monitored for the circulating EBV load showed increased viral load. One of these developed aggressive lymphoma. CD4+ lymphocytes declined from a pre-therapy median value of 425/microliter to 141/microliter post-treatment (P = 0.001). Non-hematologic toxicities were rare and mild. CONCLUSIONS: The combination of fludarabine with cyclophosphamide and dexamethasone is effective in pretreated advanced-stage low-grade NHL. It may broaden the range of therapeutic options in the salvage treatment of these patients. The main toxicity of this combination is prolonged myelosuppression that may cause treatment delay or withdrawal. The benefit of adding granulocyte colony-stimulating factor, particularly in patients with poor marrow reserve, needs to be investigated.

The immunosuppression and potential for EBV reactivation of fludarabine combined with cyclophosphamide and dexamethasone in patients with lymphoproliferative disorders.

Fludarabine is effective in chronic lymphocytic leukaemia (CLL) and low-grade non-Hodgkin's lymphoma (NHL). A major side-effect of this purine analogue is immunosuppression which may favour opportunistic infections. Additionally, impairment of immunosurveillance might promote Epstein-Barr virus (EBV) reactivation and possibly favour transformation to high-grade malignancy. The aim of this study was to evaluate the immunosuppression-related effects of the fludarabine-based combination Flucyd in advanced low-grade NHL or CLL by serially monitoring T-lymphocyte subsets, opportunistic infections, EBV-reactivation, and histologic transformation. 24 patients with advanced NHL (n = 21) or CLL (n = 3) received fludarabine 25 mg/m2/d + cyclophosphamide 350 mg/m2/d + dexamethasone 20 mg/d in 3 d courses for a maximum of six courses. The overall response rate was 79% (eight CR, 11 PR, five failures); 11 patients relapsed or progressed between 3 and 19 months from response, and eight are in CR or PR at 3-27 months. The CD4+ lymphocyte counts decreased significantly during therapy from a median of 484/microliter pre-treatment (range 142-1865) to a median of 198/microliter (71-367). In 19 responders monitored off therapy every 3 months until relapse/progression, CD4+ counts were persistently low with minimal recovery over time. During treatment, 16 infections occurred in 11/24 patients. No delayed opportunistic infections occurred in responders while off therapy. The circulating EBV DNA load serially measured in 19 patients by a quantitative PCR assay showed an increase in four patients during treatment. A lymph node biopsy performed in two of these was PCR positive for EBV DNA, whereas LMP1 and EBERs were negative. Six NHL patients evolved into high-grade B-cell NHL. In conclusion, fludarabine combined with cyclophosphamide and dexamethasone is an effective therapy for recurrent indolent lymphoma. This combination produces prolonged T-lymphocytopenia and has the potential to reactivate a latent EBV infection. T-cell dysfunction, however, is not associated with higher incidence of clinical opportunistic infections and does not adversely influence clinical outcome.

Serum CA 125 is of clinical value in the staging and follow-up of patients with non-Hodgkin's lymphoma: correlation with tumor parameters and disease activity.

BACKGROUND: CA 125 is a glycoprotein produced by epithelial ovarian tumors and by mesothelial cells; its levels also have been shown to be elevated in patients with non-Hodgkin's lymphoma (NHL). METHODS: The authors evaluated serum CA 125 levels in patients with NHL to elucidate the frequency of this finding, its relationship with other presenting features, and its potential role as tumor marker. One hundred and fifty-seven patients underwent the first CA 125 assessment at onset, 54 at disease recurrence or progression, and 62 during complete remission (CR). RESULTS: Of the 157 patients evaluated at diagnosis (median CA 125: 26 U/mL; range, 2-1400 U/mL), 63 (40%) had increased CA 125 values. Higher CA 125 levels were associated with advanced disease, aggressive histology, mediastinal and/or abdominal involvement, bulky tumor, high tumor burden, effusions, contiguous extranodal extension, high serum lactate dehydrogenase (LDH) activity, and elevated beta2-microglobulin (beta2-M) levels. Parameters identified by multivariate analysis to be independently associated with high CA 125 were: aggressive histology, mediastinal and/or abdominal disease, bulky tumor, high serum LDH activity and beta2-M serum levels, and the presence of effusion (P = 0.0000; explained variation = 0.64). Of the patients presenting with abnormal CA 125 levels, all those who achieved a CR (35) and 3 of the 6 who achieved a partial response had normalization of CA 125 values by the end of treatment. Conversely, CA 125 remained above normal values in 18 nonresponders. All 62 patients evaluated during CR showed normal CA 125 levels. Among patients first evaluated at disease recurrence or progression, 22 of 54 (41%) showed increased CA 125 levels, which were associated with the same parameters of disease found in patients examined at diagnosis. CONCLUSIONS: High serum CA 125 levels were found to correlate with mediastinal and/or abdominal involvement, high tumor mass, and effusions, reflecting the reaction of mesothelial cells to the tumor. Serum CA 125 is a reliable biologic marker for the staging and restaging of patients with lymphoma. Serial measurements are useful, in conjunction with other markers, for monitoring response to treatment.

The risk of acute leukemia in patients treated for Hodgkin's disease is significantly higher aft [see bined modality programs than after chemotherapy alone and is correlated with the extent of radiotherapy and type and duration of chemotherapy: a case-control study.

BACKGROUND AND OBJECTIVE: Patients treated for Hodgkin's disease have an increased risk of developing subsequent acute leukemia. This co-operative study was conducted to assess the relative risk associated with several candidate factors including age, splenectomy, combined modality therapy and cumulative drug dose including alkylating agents and nitrosurea derivatives. DESIGN AND METHODS: This study evaluated the risk of acute leukemia according to pretreatment variables and therapy modalities among 1659 patients treated for Hodgkin's disease and followed for a median time of 10 years. Both case-control and actuarial risk studies were performed. Median age was 34 years (range: 12-83); 53% of patients were splenectomized. As to the overall therapy, 348 patients (21%) were given radiotherapy (RT) alone, 375 (23%) chemotherapy (CT) alone (including MOPP, MOPP + ABVD or MOPP + ABVD + lomustine); 936 (56%) received both CT and RT, either as primary or salvage treatment. RESULTS: The overall 15-year actuarial risk of leukemia was 4.2%; the hazard function curve showed two peaks of risk at the 3th and the 8th year from the initiation of therapy and no leukemia beyond the 12th year of follow-up. Risk of leukemia was 0.3% after RT alone, 2.8% after CT alone (2.2% after MOPP; 4.4% after MOPP + ABVD + lomustine), and 5.4% in patients given combined modality therapy (10.2% for RT + MOPP; 15.6% for RT + MOPP + lomustine). No leukemia occurred after ABVD alone and the risk was low (0.6%) when neither mechlorethamine nor lomustine were utilized. Patients who had received extended radiotherapy including abdomen and pelvis in addition to MOPP showed a significantly higher risk of leukemia compared to those given limited RT + MOPP (P = 0.01). Case-control analysis indicated advanced stage, type and duration (> 8 months) of CT and extension of RT as significant risk factors for leukemia. Compared to RT alone, the odds ratio was 5.9 after MOPP + extended RT, and 8 when a lomustine-containing regimen was used, as well. Neither age nor splenectomy were independent risk factors for leukemia; splenectomy was influential only when patients had been given MOPP chemotherapy, as well. INTERPRETATIONS AND CONCLUSIONS: Both case-control and actuarial analyses indicated that: a) combined modality therapy with MOPP and extensive RT (including abdomen and pelvis), and the use of lomustine added to the leukemogenic risk of MOPP alone; b) programs without mechlorethamine, procarbazine and lomustine were almost devoid of leukemogenic risk.

Treatment with recombinant human erythropoietin (rHuEpo) in a patient with paroxysmal nocturnal haemoglobinuria: evaluation of membrane proteins CD55 and CD59 with cytofluorometric assay.

We describe a 28-year-old man with paroxysmal nocturnal haemoglobinuria (PNH) and a high transfusion requirement. Prior to and during therapy with recombinant human erythropoietin (rHuEpo), we evaluated the levels of 'decay-accelerating-factor', CD55, and 'membrane-inhibitor-of-reactive-lysis', CD59, as markers of the disease, whilst CD58, a marker present on leucocytes, was utilized to monitor normal haemopoietic activity. The patient became transfusion independent 1 month after beginning rHuEpo and remains well. The analysis of CD55, CD59 and CD58 suggests that the efficacy of rHuEpo was due to a selective rHuEpo action on normal erythroid clones.

Treatment outcome and prognostic factors for primary mediastinal (thymic) B-cell lymphoma: a multicenter study of 106 patients.

PURPOSE: To define clinicopathologic features, response to treatment, and prognostic factors of primary mediastinal B-cell lymphoma (MBL), a CD20+ tumor recognized as a distinct entity among non-Hodgkin's lymphomas (NHL). PATIENTS AND METHODS: One hundred six patients presented with disease confined to thorax (86%), bulky mediastinum (73%), superior vena cava syndrome (47%), and contiguous infiltration (57%). Ninety-nine received doxorubicin-containing chemotherapy (CHT). RESULTS: Thirty-five of 99 patients were primarily CHT-resistant, and 64 responded: 23 achieved complete response (CR) and 41 achieved response with residual mediastinal abnormality. Seventy-seven percent of responders received mediastinal radiotherapy (RT). Of 64 responders, 18 (28%) relapsed: none of 23 CR patients and 18 of 41 (44%) with residual mediastinal abnormality. Relapse-free survival rate of responders was 71% at 3 years. Actuarial 3-year survival rate was 52% for all patients and 82% for responders. Predictive factors of poor outcome were identified by logistic regression; Cox survival analysis was performed on death and relapse. Pericardial effusion (P < .001) and Eastern Cooperative Oncology Group (ECOG) performance status > or = 2 (P = .009) predicted nonresponse (NR) and affected survival. Less than partial midway response to CHT predicted NR to subsequent therapies. Bulky disease was related to persistent mediastinal abnormality and risk of relapse (P = .025). CONCLUSION: MBL is an aggressive NHL with unique clinicopathologic aspects, often refractory to current CHT designed for high-grade NHL. Poor performance status and pericardial effusion predict NR and poor survival. Inadequate response after the first courses of front-line CHT predicts failure of subsequent treatment. Responders with bulky mediastinum or residual mediastinal abnormality after CHT are at risk of relapse. These factors should help to select high-risk patients for intensive treatments.

Body image in secondary amenorrhea.

Body image and personality traits are described in women suffering from secondary amenorrhea. Data gathered, in 21 consecutive female patients, from the Minnesota Multiphasic Personality Inventory (MMPI), Body Cathexis Scale, Image Marking Method and Distorting Television Image Method, were examined and compared with those collected in a control group. No significant differences were found in terms of body perception and body dissatisfaction. The evaluation of MMPI profiles, on the contrary, suggested differences between amenorrheic subjects and controls for what concerned personality traits, these last being significantly, but differently, related to body dissatisfaction and wish for thinness in both groups.

Nodular lymphocyte predominance Hodgkin's disease: long-term observation reveals a continuous pattern of recurrence.

We evaluated the presenting clinical characteristics and outcome of 68 patients with nodular lymphocyte predominance Hodgkin's disease (NLP-HD), in order to delineate the pattern of evolution of the disease. The male to female ratio was 46/22 and median age 35 yrs (range, 14-86). Eight patients had a history of benign hyperplasia on lymph node biopsies performed 6 to 36 months before the diagnosis of NLP-HD. Early stage disease accounted for 75% of cases. One patient had a coexistent non-Hodgkin's lymphoma (NHL). Treatment was as follows: radiotherapy in 26, chemotherapy in 23, combined modality in 19. CR rate was 93% (63/68). 18 patients relapsed as HD and 5 developed NHL. The cumulative risk of NHL was 9% at 10 yrs. During remission, 4 patients had 5 episodes of follicular hyperplasia histologically documented. Overall survival rate was 71% at 10 yrs and and 63% at 15 yrs. Freedom from progression (FFP) declined from 67% at 5 yrs to 45% at 10 yrs, because of late relapses. Localized disease predicted for a better FFP (p = 0.01), but was not associated with a reduced risk of recurrence over time. NLP-HD is characterized by an indolent course with a constant pattern of relapse over time, also in patients with early stage disease at diagnosis. In addition to relapse as NLP-HD, patients may evolve into a NHL or develop benign lymph nodal hyperplasia. Careful long-term follow up is needed for these patients.

Primary mediastinal B-cell lymphoma: update of its clinicopathologic features.

The peculiar clinical, histomorphological and biological characteristics of PMBCL are reviewed. Special emphasis is given to the frequent aggressive clinical behaviour of this lymphoma in which conventional prognostic factors seem inadequate to identify high risk cases. The need for new clinical and/or biological prognostic markers is stressed.

Body size perception and dissatisfaction in female subjects of different ages.

The relationships between age and both body size estimation and body dissatisfaction were assessed by Distorting Television Image Method (DTIM) and Body Cathexis Scale (BCS) in a sample of 96 female subjects of ages ranging from 7 to 65 years. We found that there were no significant body distortion differences between different age ranges, although the most accurate perception seemed to occur during adolescence. As far as DTIM assessment of body dissatisfaction was concerned, adolescents showed no significantly greater aesthetic preoccupation than subjects of other age groups. On the other hand, using BCS, body dissatisfaction appeared to increase proportionally with age. The low, although significant, correlations between these two techniques of measuring body dissatisfaction suggest that, in addition to evaluating aesthetic features, BCS also assesses the degree of satisfaction with functional body aspects which are exposed to unavoidable decline with ageing.

Early-stage Hodgkin's disease: long-term results with radiotherapy alone or combined radiotherapy and chemotherapy.

BACKGROUND: Controversy still exists over the optimal management of early-stage Hodgkin's disease (HD); presentation features may have a different prognostic impact according to initial therapy, and long-term toxicity must be fully evaluated. PATIENTS AND METHODS: This study included 164 patients with stage IA-IIA HD treated with radiotherapy (RT) alone or combined radio- and chemotherapy (CT) according to presenting features and their attendant prognostic significance. The RT group included 88 patients with favorable prognostic features; the combined modality group included 76 patients with one or more unfavorable features. In the RT group, 85% of patients received extended-mantle or STNI; in the combined modality group, RT consisted of mantle- (49%), extended mantle- (37%), and involved-field irradiation (14%); CT consisted of 6 cycles of MOPP before 1984; 3 cycles of ABVD were substituted for MOPP thereafter. RESULTS: Complete remission was obtained in 94% and 99% of patients of the RT and combined modality groups, respectively. The 10-year actuarial relapse-free survival (RFS) in the RT group was 62% and was influenced by stage (p = 0.04) and histology (p = 0.01); in the combined modality group, RFS was 88% and was influenced by the presence of bulky disease. Overall survival and tumor mortality between the therapy groups were comparable. RT-related toxicity consisted of mediastinal fibrosis (8 cases), myelitis (3), hypothyroidism (2); other long-term events included 2 cases of acute leukemia in the combined MOPP and RT group. Altogether, 8 of 20 patients who died were in their first complete remission. CONCLUSIONS: In stage IA-IIA HD, the combined modality therapy reduced the risk of relapse compared to radiation alone; long-term toxicity of RT was not negligible and relapses could occur late.

Analysis of long-term results and prognostic factors among 138 patients with advanced Hodgkin's disease treated with the alternating MOPP/ABVD chemotherapy.

BACKGROUND: A prospective study was conducted to assess (a) the long-term results and toxicity of the alternating MOPP/ABVD regimen in advanced Hodgkin's disease; (b) the prognostic value of pretreatment variables and of drug dose intensity. PATIENTS AND METHODS: A total 138 consecutive patients with advanced Hodgkin's disease entered this study; patient selection included stages IIB (33% of total), IIIB (26%), IV (25%), and stages IIA-IIIA (16%) with bulky disease and pulmonary hilum involvement. The MOPP/ABVD program was delivered in an 8-month program; adjuvant radiotherapy on sites of bulky disease was delivered in 24 patients. RESULTS: Complete remission was obtained in 106 (77%) patients; significant factors for CR in univariate analysis were stage, symptoms, histology, and bone marrow involvement. The five-year relapse-free survival (RFS) was 83%; in a multivariate analysis, histology only correlated with RFS (p = 0.04). The five-year freedom from tumor mortality and overall survival (OS) were 79% and 67%, respectively. An adverse prognostic significance for OS was observed for B symptoms and bone marrow involvement. The median percentage of relative dose intensity (RDI) was as follows: Adriamycin 86, mechlorethamine 85, vincristine 73, vinblastine 84, bleomycin 79, procarbazine 74, dacarbazine 81. No significant association was found between RDI and clinical outcome. No severe pancytopenia or life-threatening complications occurred during therapy. CONCLUSIONS: Alternating MOPP and ABVD cured more than 65% of patients with advanced HD; acute and late toxicity were acceptable. Prognostic analysis defined subgroups with a lower chance of cure which may deserve a more intensive initial therapy.

P-VEBEC: a new 8-weekly schedule with or without rG-CSF for elderly patients with aggressive non-Hodgkin's lymphoma (NHL).

BACKGROUND: Chemotherapy regimens devised for elderly patients with intermediate-high grade NHL are a matter of discussion. The aim is to reduce general toxicity without loosing an antilymphoma effect. The most important limiting factor of chemotherapy is myelotoxicity; for this reason the use of growth factor may be useful in these patients. PATIENTS AND METHODS: From November '91 to November '92, 67 pts older than 65 years with intermediate-and high-grade advanced-stage NHL were treated with the P-VEBEC regimen, an original scheme with epirubicin 50 mg/m2, cyclophosphamide 350 mg/m2 and etoposide 100 mg/m2 on weeks 1, 3, 5, 7; vinblastine 5 mg/m2 and bleomycin 5 mg/m2 on weeks 2, 4, 6, 8, prednisone 50 mg/m2/day p. os in the first 2 weeks and thereafter every other day. Twenty-eight pts received r-GSF 5 micrograms/kg/day throughout the treatment starting on day 2 of every week for 4 consecutive days. Their median age was 71 years (65-80), 31 pts were male and 36 female, histology according W.F. was D 6; E 17; F 16; G 19; H 9. Twenty-five percent of pts had B symptoms, 35% had bulky disease, 41% LDH level > normal, 44% stage IV and 26% had B.M. involvement. RESULTS: C.R. was achieved by 66% of pts. Adverse prognostic factors for CR were E histology, stage IV, bone marrow infiltration and LDH above normal. Severe toxicity was never recorded, no toxic death was observed. With a median follow-up of 24 months OS, DFS and EFS were 55%, 52%, and 33%, respectively. EFS was influenced by stage, BM involvement and level of LDH. The relative dose intensity (RDI) was calculated by the method of Hryniuk and Bush. Patients who received rG-CSF had a significantly higher median RDI (94% vs 79%) and lower myelotoxicity (neutrophil nadir < 500 18% vs 56%). The rate of CR was influenced by RDI > 80% (89% vs 56%). EFS was also better in pts who received a RDI higher than 80% (50% vs 18% p = 0.05). CONCLUSION: P-VEBEC is a feasible cycle in elderly patients; the use of rG-CSF improves RDI. In patients with adverse prognostic factors (BM involvement, poor performance status) a RDI > 0.80 could play a role in improving the outcome.

Results of CAV regimen (CCNU, melphalan, and VP-16) as third-line salvage therapy for Hodgkin's disease.

BACKGROUND: A prospective study was conducted to assess the efficacy and toxicity of a salvage regimen consisting of CCNU, Melphalan, and VP-16 (CAV) given at 28-day intervals in patients with Hodgkin's disease (HD) relapsing after primary therapy or refractory to the alternating MOPP/ABVD regimen. PATIENTS AND METHODS: This study included 58 patients (median age: 34 years), with resistant or relapsing HD. Primary therapy had consisted of alternating MOPP/ABVD (81%) or MOPP alone (19%); 38% of patients were relapsing from prior complete remission (CR) while 62% had resistant disease. Extranodal disease was present in 55% and B-symptoms in 72% of patients; one-fifth had bulky disease and/or bone marrow involvement. The CAV was used as first salvage in half of the patients. RESULTS: Complete remission was obtained in 17 patients (29%); unfavorable factors for CR in univariate analysis were the presence of bulky disease and the failure to achieve CR with prior therapy. Nine patients (53% of remitters) have subsequently relapsed with a 10-month median duration of CR. The 3-year overall survival after CAV was 25% with an 18-month median survival; significant differences in survival were found according to the extent of disease, the presence of B-symptoms and the HD status (prior sensitive or resistant disease, first or subsequent relapse). Seven patients are long-term remitters (12%), and one of them has been given high-dose chemotherapy and autologous bone marrow transplantation at relapse after CAV. The CAV toxicity was mostly hematological; severe pancytopenia occurred in six cases with two cases of fatal infections and one of fatal hemorrhage. CONCLUSION: CAV therapy was moderately effective as third-line salvage in patients with HD resistant to alternating MOPP/ABVD or previously given two different regimens for relapse; the toxicity was mostly hematological and supportive therapy was needed in one-third of the patients.
