Fludarabine treatment in resistant Waldenstrom's macroglobulinemia.
Fludarabine (FLU) is a fluorinated purine analogue with a promising antineoplastic activity in lymphoproliferative disorders. In this study, we evaluated the efficacy of FLU in 12 previously treated (primary refractory and refractory relapse) patients with Waldenstrom's macroglobulinemia. All patients were treated at a dosage of 25 mg/m2 per day for 5 consecutive days for a total of six courses. Of the 12 patients, 5 (41%) achieved partial response (PR), and the remaining 7 showed no benefit from the treatment. An increased response rate was obtained in the 4 primary refractory patients in which 2 PR were documented. Treatment was well-tolerated and there were no Fludarabine-related fatalities. With a mean follow-up of 10 months, only 1 PR patient has relapsed. Fludarabine is an interesting new salvage agent effective against recurrent/resistant Waldenstrom's macroglobulinemia and should be evaluated in further studies in untreated patients with Fludarabine in monochemotherapy or in combination with other active modalities.

Primary gastric lymphoma: a clinical and therapeutic evaluation of 82 patients.
Eighty-two patients with primary gastric (IE, II1E, and II2E) non-Hodgkin's lymphoma according to the Musshoff's staging system were treated with combined modality including surgery with/without radiotherapy between January 1985 and December 1991. According to the Updated Kiel classification 54 had high-grade histologic subtypes and 28 low-grade. The strategy throughout the study was to resect primary tumor: all patients underwent gastrectomy, 40 subtotal and 42 total gastrectomy. The resection permitted complete surgical staging utilizing three pathologic features: disease confined within or beyond the serosa, negative/positive regional lymph nodes, and negative/positive surgical margins. If there was no evidence of these pathologic factors, the patients who underwent surgery alone received no further radiotherapy. On the other hand, all patients who presented at least one of three pathologic factors were treated with adjuvant radiotherapy after the resection. All except 14 patients presented at least one of the pathologic features and 50 (61%) patients had involvement of the whole gastric wall. Radiotherapy included the gastric bed and para-aortic lymph nodes and, for the patients, who had positive regional lymph nodes in combination with the complete involvement of the gastric wall, the irradiation included the whole abdominal approach. The complete response rate was 97% and the 9-year disease-free survival was 93%. All but one of the 5 relapses occurred within 18 months stressing the need for more specific staging. Gastric resection with/without radiotherapy may still represent the primary therapeutic procedure in early stage gastric non-Hodgkin's lymphoma.

[Combined treatment of stage I and II gastric lymphoma].
From 1981 to 1991, fifty-three patients with primary gastric lymphoma were referred to our Institute and submitted to a complete pathologic staging followed by gastric resection, i.e., total or partial gastrectomy. According to the Working Formulation criteria, 14 patients (26.4%) were affected with high grade lymphomas, 22 (41.5%) with intermediate lymphomas and 17 (32.1%) with low grade lymphomas. MALT (mucosa associated lymphoid tissue) lymphomas were observed in > 50% of cases. At the pathologic examination of the surgical specimens, infiltration depth was assessed, according to TNM criteria, in the patients whose disease was limited to the muscular gastric wall (T1-T2) and in those whose disease spread to the serosa or beyond it (T3-T4). Twenty-five patients were classified as stage I and 28 as stage II (9 of them in stage II E1 and 19 in stage II E2 according to Musshoff's classification). The treatment protocol of these patients was as follows: stage I patients (T1-T2) with normal surgical resection margins underwent no adjuvant treatment (10 patients); stage I patients (T1-T2) with resection margins infiltrated by the disease were submitted to local irradiation; stage I (T3-T4) and stage II E1 patients underwent large-field postoperative irradiation (14 patients); stage II E2 patients (n = 19) received conventional chemotherapy (CHOP, F-CVP, N-CVP): the ones who failed to reach complete remission or presented with bulky disease at diagnosis completed the treatment with large-field irradiation (10 patients). The disease-free survival (86.5%) and the overall survival (96%) rates of stage I patients exhibited no significant difference relative to stage II patients (DFS: 87% and OS: 90%). The analysis of relapses relative to disease extent demonstrated that this parameter is more significant to prognosis than nodal involvement (T1-T2: 2/39 relapses, 5.1%; T3-T4: 4/14 relapses, 28.6%).

Proliferative response of human marrow myeloid progenitor cells to in vivo treatment with granulocyte colony-stimulating factor alone and in combination with interleukin-3 after autologous bone marrow transplantation.
We have recently reported that the hematologic recovery of patients with non-Hodgkin's lymphoma (NHL) and Hodgkin's disease (HD) undergoing autologous bone marrow transplantation (BMT) is significantly faster when recombinant human interleukin-3 (rhIL-3) is combined with recombinant human granulocyte colony-stimulating factor (rhG-CSF) in comparison with patients receiving G-CSF alone. In this paper, we studied the kinetic response and concentration of BM progenitor cells of 17 patients with lymphoid malignancies submitted to autologous BMT and treated with the G-CSF/IL-3 combination. The results were compared with those of five lymphoma patients receiving the same pretransplant conditioning regimen followed by G-CSF alone. rhG-CSF was administered as a single subcutaneous (sc) injection at the dose of 5 micrograms/kg/d from day 1 after reinfusion of autologous stem cells; rhIL-3 was added from day 6 at the dose of 10 micrograms/kg/d sc (overlapping schedule). In both groups (G-CSF- and G-CSF/IL-3-treated patients), cytokine administration was discontinued when the absolute neutrophil count (ANC) was >0.5 x 10(9)/L of peripheral blood (PB) for 3 consecutive days. After treatment with the CSF combination, the percentage of marrow colony-forming units-granulocyte/macrophage (CFU-GM) and erythroid progenitors (BFU-E) in S phase of the cell cycle increased from 9.3 +/- 2% to 33.3 +/- 12% and from 14.6 +/- 3% to 35 +/- 6%, respectively (p < 0.05). Similarly, we observed an increased number of actively cycling megakaryocyte progenitors (CFU-MK and BFU-MK). Conversely, G-CSF augmented the proliferative rate of CFU-GM (22.6 +/- 0.6% compared to a baseline value of 11.5 +/- 3%; p < 0.05) but not of BFU-E, CFU-MK, or BFU-MK, and the increase of S-phase CFU-GM was significantly lower than that observed in the posttreatment samples of patients receiving IL-3 in addition to G-CSF. The frequency of hematopoietic precursors in the BM, expressed as the number of colonies formed per number of cells plated, was unchanged or slightly decreased in both groups of patients. Because of the increase in marrow cellularity, however, a significant augmentation of the absolute number of both CFU-GM (3605 +/- 712/mL BM vs. 2213 +/- 580/mL; p < 0.05) and BFU-E (4373 +/- 608/mL vs. 3027 +/- 516/mL; p < 0.05) was reported after treatment with G-CSF/IL-3 but not G-CSF alone. Similarly, administration of the cytokine combination resulted in a higher number of CD34+ cells/mL BM, and their concentration was significantly greater than that observed in the posttreatment samples of G-CSF patients. Finally, we investigated the responsiveness to CSFs, in vitro, of highly enriched CD34+ cells, collected after priming with G-CSF in vivo (i.e., after 5 days of G-CSF administration). Our results demonstrated that pretreatment with G-CSF modified the response of BM cells to subsequent stimulation with additional CSFs. The results presented in this paper indicate that in vivo administration of two cytokines increases the proliferative rate and concentration of BM progenitor cells to a greater degree than G-CSF alone. These results support the role of growth factor combinations for accelerating hematopoietic recovery after high-dose chemotherapy.

[Bulky mediastinal lymphomas: role of magnetic resonance and SPECT-Ga-67 in the evaluation of residual masses].
A residual mediastinal mass is a common finding during and/or after treatment for bulky mediastinal lymphoma and represents a difficult diagnostic problem. For correct therapy modulation, fibrosis must be distinguished from active disease. To assess diagnostic imaging potentials in the characterization of residual masses, 41 patients with bulky mediastinal lymphoma were examined with CT, MRI and Ga67-SPET; 92 examinations were performed for each technique: 14 before treatment, 42 during and after chemotherapy, 13 after radiotherapy and 23 six months after the end of treatment. CT provides useful pieces of information on tumor size but fails to depict tissue changes: therefore, only MR and SPET results were considered and compared with clinico-biological and follow-up findings. MRI and SPET were often in agreement with each other (78/92 cases) and with clinical data (98.7%); each examination yielded only one false positive. In case of disagreement (14/92 patients), MRI yielded more false-positive findings because it failed to differentiate neoplastic tissue from treatment-related conditions, i.e., granulation tissue, inflammation, necrosis, early fibrosis. In contrast, negative MR results were more reliable, MR negative predictive value being 100%. Ga67-SPET exhibited high sensitivity (97.1%) and specificity (91.2%), with fewer false positives than MRI (5 vs. 10). In conclusion, both examinations were accurate in the characterization of residual mediastinal masses during and after therapy, but MRI had higher sensitivity and Ga67-SPET higher specificity. Therefore, the authors acknowledge the complementary role of these two techniques and the necessity of an integrated approach, i.e., combined MRI and Ga67-SPET or CT and Ga67-SPET.

CEP regimen (CCNU, etoposide, prednimustine) for relapsed/refractory Hodgkin's disease.
AIMS AND BACKGROUND: Although initial treatment of Hodgkin's disease induces a complete remission in most patients, approximately 50% of patients with advanced disease will not achieve a complete remission or will relapse following the first complete remission. PATIENTS AND METHODS: Twenty-three patients with relapsed/resistant Hodgkin's disease, observed between January 1991 and October 1993, underwent CEP combination chemotherapy (CCNU, etoposide, prednimustine). All patients had previously received MOPP and ABVD regimens, in combination at diagnosis or sequentially (at diagnosis and at the first relapse). RESULTS: Thirteen (56%) patients achieved complete responses and 4 (18%) had partial responses. Two partial responders obtained a complete remission after a successive autologous bone marrow transplantation. The complete remission was not influenced by the timing of MOPP and ABVD treatments, presence of extranodal involvement or presence of bulky disease, but was affected by the presence of a primary disease refractory to the first standard programs. All the complete responders but 2 were alive and relapse-free at a median follow-up of 15 months; no major toxic effects were recorded. CONCLUSIONS: These data suggest, as did those of other studies, that CEP is an effective regimen in patients with Hodgkin's disease in first or second relapse, also to reduce the tumor burden and to determine chemosensitivity before contingent bone marrow or peripheral blood stem cell support.

Anaplastic large cell lymphoma (CD30 +/Ki-1+): results of a prospective clinico-pathological study of 69 cases.
Sixty-nine anaplastic large cell lymphomas (ALCLs) were selected from an Italian comparative trial on MACOP-B and F-MACHOP. As no significant difference in effectiveness of the protocols emerged, they were considered homogeneously treated. The ALCLs were divided into two groups according to previously defined criteria: 41 were common type (ALCLs-CT) and 28 Hodgkin-related (ALCLs-HR). T-cell phenotype was most common (58%), while B-cell, null and hybrid forms accounted for 27%, 13% and 2%. Clinically, ALCLs CT and HR differed as to mean age (27 v 34.3 years) and presentation; all ALCLs-HR showed mediastinal involvement, with bulky disease in 57%, and more frequent occurrence in stage II. In contrast, ALCLs-CT showed mediastinal masses in 58.5%, infrequently revealed bulky disease (24%), and were not specifically associated to stage. Among the ALCLs-CT, 68.4% achieved complete remission (CR), 24.4% partial remission (PR), one (2.4%) was resistant to therapy, and two (4.8%) had fatal drug toxicity. Of the ALCLs-HR, 67.8% reached CR, 14.3% PR, and 17.9% did not respond. In CR, ALCLs-CT showed a greater tendency to relapse (32.1% v 14.2%). At present, 65.8% of ALCLs-CT and 67.8% of ALCLs-HR are alive with overall survival/disease-free survival averages of 31/27 and 29/24 months respectively. Our data emphasize that, independently of subtype, ALCLs benefit from the application of third-generation protocols for high-grade non-Hodgkin's lymphomas.

Treatment recommendations for osteosarcoma and adult soft tissue sarcomas.
During the past 20 years, dramatic improvements have been obtained in the treatment of localised osteosarcoma of the extremities, both in the rates of disease-free survival and in quality of life. Twenty years ago 80 to 90% of the patients died, in spite of mutilating surgery, but now about 75% survive and avoid the necessity of amputation. This is due to the introduction of very effective combined treatments, mostly also using preoperative chemotherapy. One of the major issues is that of intensive preoperative chemotherapy, which improves both limb salvage and survival. A multidisciplinary approach is necessary to obtain good results. When the role of adjuvant or neoadjuvant chemotherapy is not accurately defined for soft tissue sarcomas, particular emphasis is given to the staging of the diseases and to the important role of local treatment in the survival of these patients. A combination of radiation therapy and surgery is strongly recommended.

Adult Burkitt's lymphoma: clinical and prognostic evaluation of 20 patients.
Burkitt's lymphoma (BL), a rapidly growing lymphoma, is recognized by its aggressive course, brief median survival, and low rates of long-term survival for patients. Several polychemotherapeutic approaches are utilized. Twenty adult patients with BL identified according to the Kiel classification were analysed retrospectively. Therapeutic modifications depended upon the different times of the diagnosis. Eight patients received the LSA2-L2 regimen, 11 patients were treated with third generation polychemotherapeutic regimens for high-grade non-Hodgkin's lymphomas: F-MACHOP and MACOP-B, and 1 elderly patient was given the COP regimen. Of the 11 patients treated with cyclic conventional therapy (7 with F-MACHOP and 4 with MACOP-B), 8 achieved a complete response (CR). Of the 8 patients who were given the LSA2-L2 protocol, 4 obtained a CR. One elderly patient treated with the COP regimen obtained a partial response. Early stage of disease, low levels of LDH, and the absence of bone marrow involvement were characteristics of patients with good prognoses. Effective conventional third-generation polychemotherapy regimens (F-MACHOP and MACOP-B), normally used for high-grade non-Hodgkin's lymphomas, were equally effective for a large fraction of adults with BL. Furthermore, our study confirms the important role of LDH level, stage, and bone marrow involvement as prognostic factors in BL as well as the roles of tumor burden in the CR rate and relapse-free survival.

Radiotherapy in early stage Hodgkin's disease.
Ninety-nine patients with "standard risk" Stage IA-IIA Hodgkin's disease observed between January 1983 and December 1990, received radiotherapy only. The complete response rate was 98% (97/99). Twenty-one patients (21%) relapsed, 17 of whom (81%) obtained a second complete remission. The projected 9-year overall survival and disease-free survival were 95% and 78%, respectively. In this study our goals were to reduce the irradiation volumes, to decrease the number of splenectomies performed at diagnosis, and to utilize radiotherapy alone in these patients. We were able to reduce the irradiation volumes in over 50% and 80% of the patients with disease in the upper torso and subdiaphragm, respectively. Furthermore, this therapeutic approach permitted us to reduce the acute and long-term toxic effects related to splenectomy and combined modality treatment.

[Anaplastic large-cell lymphoma. Conceptual and diagnostic assessment].
The authors critically review the concept of anaplastic large cell lymphoma (ALCL). In particular, they provide the guidelines to the morphologic identification of the four main varieties of the tumour: common, giant-cell-rich, lympho-histiocytic, and Hodgkin's-like. The phenotypic and molecular characteristics of the neoplasm are discussed with special emphasis to those which can assist in the differential diagnosis between ALCL and Hodgkin's disease. Finally, the clinical features are presented along with the results obtained in the course of long-term prospective therapeutical trials.

Primary chemotherapy and delayed surgery for nonmetastatic osteosarcoma of the extremities. Results in 164 patients preoperatively treated with high doses of methotrexate followed by cisplatin and doxorubicin.
BACKGROUND: Neoadjuvant chemotherapy is the most accepted treatment for localized osteosarcoma. This has led to a great improvement in limb-sparing surgery and in disease-free survival. Patients with a good response to preoperative chemotherapy showed a higher disease-free survival rate. Current studies examine the possibility of patients whose limbs could be rescued with a poor necrosis and a reduction of the side effects related to aggressive treatments. METHODS: Between September 1986 and December 1989, 164 patients entered the second neoadjuvant study conducted at the Rizzoli Institute, Bologna, Italy, for non-metastatic osteosarcoma of the extremities. Preoperative chemotherapy consisted of two cycles of high-dose methotrexate intravenously (i.v.) followed by cisplatin intraarterially and doxorubicin i.v. After surgery, patients classified as good responders (> 90% tumor necrosis) received three more cycles of these drugs, whereas poor responders (< 90% tumor necrosis) had more chemotherapy, which included ifosfamide and etoposide in addition to the other three drugs. RESULTS: Limb salvage was performed in 83% of cases. At an average follow-up of 54 months (36-76), 109 patients (66%) were continuously disease-free, 2 died from doxorubicin cardiotoxicity, and 52 experienced metastases and 3 had local recurrence. In two of these three patients, metastases followed local recurrence. The 5-year actuarial continuously disease-free survival rate was 63%, with no differences between good and poor responders. Excluding 20 patients who had major protocol violations, the projected continuous disease-free survival rate was 71%. CONCLUSIONS: With an aggressive neoadjuvant chemotherapy, it is possible to cure more than 60% of nonmetastatic osteosarcoma of the extremities, avoiding amputation in most cases. Ifosfamide and etoposide seem to be effective in patients who did not respond to preoperative chemotherapy.

Comparison between the monoclonal antibodies Ki-67 and PC10 in 125 malignant lymphomas.
The monoclonal antibody (MAb) Ki-67 detects a nuclear proliferation-associated antigen which corresponds to a non-histone protein with a molecular weight of 395 and 345 kD. Its prognostic relevance has been assessed in both lymphoid and non-lymphoid tumours. The MAb PC10 picks up the proliferating cell nuclear antigen (PCNA), which is a 36 kD nuclear protein associated with the cell cycle. Whereas Ki-67 works only in fresh material, PC10 detects a fixation-resistant epitope of PCNA. Preliminary data have revealed a linear relationship between Ki-67 and PC10 reactivity in normal lymphoid tissue and in non-Hodgkin's lymphomas (NHLs). We applied Ki-67 and PC10 to frozen and routine sections, respectively, from 25 examples of Hodgkin's disease (HD) (14 nodular sclerosis, 6 lymphocyte predominance, 5 mixed cellularity) and 100 NHLs (corresponding to the main varieties of the updated Kiel classification). The results obtained can be summarized as follows: (1) both MAbs gave rise to extremely variable results within the same category of NHLs; (2) most Hodgkin and Reed-Sternberg cells (50-98 per cent) were labelled by the reagents; (3) Ki-67 and PC10 stained a similar ratio of neoplastic cells in 65 and 76 per cent of NHL and HD cases, respectively; in the remaining instances, no correspondence was observed, the PC10-positive elements usually outnumbering the Ki-67-positive ones significantly. These discrepancies, which might be due to low PCNA catabolism and/or PCNA expression by quiescent cells, underline the need for further kinetic and clinico-pathologic studies in order to define the specific relevance of PC10.

Correlations between apoptotic and proliferative indices in malignant non-Hodgkin's lymphomas.
Cell production versus cell loss rates were estimated, across the boundaries of histological classification, in 50 cases of malignant non-Hodgkin's lymphomas by use of mitotic indices, percentage of Ki-67+ cells and percentage of PC10+ cells as proliferative indices, and the relative number of apoptotic bodies (apoptotic indices, AIs) as parameters. Regression analysis revealed significant (P < 0.01) positive correlations between the AIs and the proliferative indices; among the immunohistochemically assessed proliferative indices; and between these, the mitotic indices and the AIs on the one hand and histological malignancy grades on the other hand. The cellular protein BCL-2, which counteracts apoptosis, was significantly (P < 0.01) more often expressed in lymphomas with low than in those with high AIs. Multivariate analysis of data showed that of all parameters tested in this series, only the AIs correlated significantly (P < 0.05) with overall lethality. The correlation between BCL-2 positivity of lymphoma cells and overall survival did not quite attain significance (P = 0.08). Results of the present study suggest that high AIs and lack of BCL-2 expression may be adverse prognostic factors, independent of histological grade.

Hypercoagulability in patients undergoing autologous or allogeneic BMT for hematological malignancies.
Severe thrombotic alterations, such as veno-occlusive disease of the liver, may occur in the early phase following high-dose chemoradiotherapy and BMT. In this study, performed in patients with hematological malignancies subjected to allogeneic (10 cases) and autologous (20 cases) BMT, we have monitored laboratory hemostatic parameters to better understand the pathogenetic mechanism of thrombosis and particularly of veno-occlusive disease. Prothrombin time, activated partial thromboplastin time, plasma fibrinogen, markers of hypercoagulability (thrombin-antithrombin complex and prothrombin fragment F1+2); natural anticoagulants (protein C, protein S and antithrombin) together with fibrinolytic parameters (plasminogen, alpha 2-antiplasmin, tissue-plasminogen activator, plasminogen activator inhibitor and D-dimer) were assessed before transplant, on day 0 and weekly for 1 month thereafter. A hypercoagulability state, not related to an impairment of the anticoagulant and fibrinolytic systems, was documented before and after autologous and allogeneic transplant. Two patients developed veno-occlusive disease: they did not show any difference from the other patients before transplant while they presented a decrease of the natural anticoagulants along with altered fibrinolytic parameters only at the clinical onset of veno-occlusive disease. In conclusion, in this study a state of marked hypercoagulability was documented in BMT patients and the hemostatic laboratory parameters evaluated were not able to predict the occurrence of the thrombotic complications.
