Soft tissues sarcoma with acute paraneoplastic hepatic dysfunction: case report.

A case of malignant fibrous histiocytoma of soft tissues of the right scapula associated with transitory hepatic dysfunction in the absence of liver metastases is reported. After primary radiation therapy, the patient manifested fever, anemia, thrombocytosis and hepatic dysfunction. All the abnormalities disappeared immediately after complete removal of the tumor. The patient was well, with no evidence of distant metastases, at more than 12 months later. It is concluded that the abnormalities of laboratory data were indirectly induced by the tumor, although the exact mechanism of this paraneoplastic syndrome was not clarified.

Non conventional fractionation in radiotherapy of the musculo-skeletal sarcomas.

In 1989 we started an accelerated hyperfractionated schedule of radiotherapy (two 1.6 Gy daily fractions) in standard risk localized Ewing's sarcoma of bone, with the aim at reducing late effects in young patients and at improving disease control through a better integration of treatment modalities. From 1991, the same schedule was used in preoperative radiotherapy of adult soft tissue sarcomas of the extremities: the main purpose was to reduce the time to surgery and to evaluate surgical complications in comparison with a previous experience of hypofractionated radiotherapy (one 3 Gy daily fraction). From 1991 to 1997, 76 patients with Ewing's sarcoma and 24 patients with soft tissue sarcoma were treated at our Institution. Results and complication rates are analyzed in comparison with historical data. In Ewing's sarcoma, a correct evaluation of improvement in local control was difficult because of changing treatment policy (bulky disease was not included in the present series). Late effects, as evaluated in patients with a minimum follow-up of 3 years, occurred with similar incidence, but at higher total dose levels in patients treated with accelerated hyperfractionation. In patients with soft tissue sarcomas, incidence of surgical complications is reduced as compared to historical experience. Major problems of wound healing were seen in association with intraoperative brachitherapy boost.

MACOP-B regimen followed by involved-field radiation therapy in early-stage aggressive non-Hodgkin's lymphoma patients: 14-year update results.

A single-center, retrospective study was conducted to evaluate therapeutic results of the MACOP-B third-generation chemotherapy regimen followed by involved-field radiation therapy in a stage I-II aggressive non-Hodgkin's lymphoma (NHL) patients. From 1986 to 1995, 118 consecutive patients with the diagnosis of aggressive NHL, stage I-IE or II-IIE, with or without bulky disease were treated with MACOP-B regimen followed, when appropriate, by 30-36 Gy involved-field radiation therapy. The complete response (CR) rate was 95% after the combined modality treatment (97% for stage I-IE and 93% for stage II-IIE). Patients with bulky disease had a CR rate of 92%. Treatment was well tolerated and no deaths occurred from acute toxicity. After a median follow-up of 68 months, 24 (21%) patients relapsed. The 14-year projected relapse-free and overall survival rates were 78% and d 69%, respectively. MACOP-B regimen with/without involved-field radiation therapy provides a safe and effective combined modality treatment for early-stage aggressive NHL, with the possibility to definitively cure two thirds of the patients.

Hodgkin's disease: summary of twenty years' experience.

BACKGROUND: A retrospective analysis on HODGKIN'S DISEASE (HD) was finalized to see if changing the management and therapy during the years we improved the cure rate of lymphomas and reduced the incidence of side effects due to therapy. Up to twenty years' experience was based in two major therapeutic periods: the first included patients observed between 1970 and June 1980 and the second between July 1980 and December 1987. Significant differences between the two periods were the reduction of splenectomies as staging procedure, the reduction of radiation dose and extension and the sequential use of MOPP/ABVD instead of MOPP alone. METHODS: The analysis included all patients observed over the twenty years under study by looking to the differences concerning response to therapy, survival, relapse-free survival and major consequences due to therapy, namely death not directly related to lymphoma. 377 pts entered the first period and 193 the second one with a minimum follow-up of 4 years. RESULTS: Significant differences were recorded on CR rate, 80.9% vs 90.5%, respectively (p = 0.0024) and deaths in CR, 15.1% vs 2.6%, respectively (p = 0.000). The overall survival shows a probability of 60% and 83% at 11 years for the first and the second group, respectively (p = 0.000) being the probability of survival of 50% at 20 years for the first group of pts. The probability of being in remission is similarly of 79% and 78%, for the first and second group, respectively. The risk of death in remission accounting all causes not related to lymphoma shows a 17% probability vs 6% at 11 years (p = 0.006) for the first and second group, respectively, being 38% for the former group at 20 years. The most frequent single cause of death in remission was secondary leukemia which was recorded in 14 pts on the group of pts observed between 1970 and 1980, all splenectomized and treated by MOPP and extensive radiotherapy. CONCLUSIONS: The modifications of therapy of HD have produced improvements concerning the prognosis of pts; these improvements are due mainly to the reduction of late side effects such as acute leukemia and second solid tumor, and to the increase of remission rate and cure rate of the lymphoma.

"Very late" relapses in Hodgkin's disease patients: a rare but real phenomenon.

In the past several decades, scientific and therapeutic advances have transformed Hodgkin's disease from a uniformly fatal illness to one that can be treated with the expectation of long-term remission or cure in the majority of cases. Because patients now survive for long periods after treatment, various late complications are being identified. Among patients with such late complications, some have been reported to experience "very late" relapses (> 10 years). Here we document recurrences in three patients with Hodgkin's disease more than 10 years after remission.

The evolution of integrated treatment of soft tissue sarcoma at the Rizzoli Orthopaedic Institute.

The authors take into consideration all types of treatment used at the Rizzoli Orthopaedic Institute and in associated centers over the last 40 years for soft tissue sarcoma of the limbs. For each clinical study the most up-to-date results are reported with statistical evaluations. From the first protocol that used adriamycin alone and up to the beginning of the eighties, we then go on to a second-generation study in the nineties that used adriamycin and ifosphamide at a high dosage. The pilot study that was used at the end of the nineties to evaluate the validity of the use of chemotherapy and radiotherapy is considered, as is the study currently being conducted by the Italian Sarcoma Group. Conclusions based on our vast previous experience lead us to believe that adjuvant chemotherapy must be used for all patients with high-risk soft tissue sarcoma within clinical trials.

Hodgkin's disease: update of findings.

The authors critically review the problem of Hodgkin's disease (HD) in the light of new morphological, immunohistochemical, kinetic, genotypic, and virological findings. These support the lymphoid origin of neoplastic Hodgkin's and Reed-Sternberg cells, because of regular expression of the CD30 lymphoid activation antigen and frequent detection of B- or T-cell phenotypic and/or genotypic markers. It is possible to hypothesize the release of cytokines by tumoral elements as well as the presence of specific cytokine receptors on their surface. This might explain some clinical and pathological features, such as fever, loss of weight, eosinophilia and attraction of reactive elements that make up the composite cellular milieu of typical HD. Integration of monoclonal EBV in the genoma of neoplastic elements has repeatedly been shown, and this might play an essential role in the pathogenesis of the disease. On the basis of present concepts, the borderlines between HD and some categories of non-Hodgkin's lymphomas--especially the anaplastic large cell forms--have become somewhat blurred. Additional research work in the field of HD is desirable and might pave the way for new and more effective therapeutic approaches, designed on the basis of the natural history of the neoplasm.

MN (N = Novantrone) COP-B therapy on high and intermediate grade non-Hodgkin's lymphoma: an alternative to MA (A = adriamycin) COP-B?

BACKGROUND AND METHODS: From February, 1987 to August, 1988, fifty-one patients with high and intermediate grade non-Hodgkin's lymphoma (NHL) entered a chemotherapy program MNCOP-B (M = Methotrexate, N = Novantrone, C = Cytoxan, O = Oncovin, P = 6 methyl-prednisolone, B = Bleomycin). Forty patients received MNCOP-B as first-line therapy and 11 patients as salvage therapy after relapse-resistance to other schemes or radiotherapy. RESULTS: The overall remission rate was 51% with a similar distribution of remissions between the two groups under study. At a mean follow-up of 28 months, 20 patients (40%) remain in CR with a disease-free probability of 83% for patients treated with MNCOP-B as up-front therapy and 67% for patients treated with MNCOP-B as salvage therapy. The overall survival at 3 years is 45%; bulky, disease stages III-IV and symptoms are not correlated with poorer survival or a lower remission rate. Patients who received less than 70% of the scheduled doses paradoxically figure better than the others, showing an 87% remission rate, as compared to those who received 100% of the scheduled doses and obtained a 35% remission rate. Major toxicity consisted of mucositis, recorded in 15% and 9% of previously untreated and treated patients, respectively; severe neutropenia was recorded in 27% and 63%, respectively. Despite the number of recorded side effects, only one toxic death due to sepsis occurred. CONCLUSIONS: MNCOP-B is an effective regimen in intermediate and high grade NHL and easily manageable in the out-patient clinic. The incidence of mucositis is sensibly reduced as compared to the parental regimen MACOP-B reported in the literature; this result allows the use of MNCOP-B in older patients.

Mycosis fungoides: a therapeutical review.

In this review of current therapy for mycosis fungoides, the analytical data have been extrapolated from the literature. We have considered the various therapeutic modalities such as topical therapy, photochemotherapy, electron beam radiation therapy, systemic chemotherapy, the combined modalities, as well as the use of interferon and other alternative biological approaches. We conclude with a final section on comments and recommendations that may prove useful in the design of appropriate therapeutic strategies.

Fifteen-year experience in Hodgkin's disease: role of combined modality treatment and splenectomy in the incidence of secondary acute leukemia.

BACKGROUND: Following irradiation alone, secondary acute leukemia is extremely uncommon; following chemotherapy alone, the risk is increased, but not as much as when continued maintenance chemotherapy or combined modality treatments are used. PATIENTS: The risk of secondary acute nonlymphocytic leukemia (ANLL) was assessed in 552 patients with Hodgkin's disease (HD), who were diagnosed at the Hematology Institute of Bologna from 1970 through 1984 and followed-up through July, 1990. Median follow-up time was 12 years. RESULTS: ANLL developed in 14 of 328 patients treated with the combined modality of extended-field radiotherapy (RT) plus chemotherapy (CT). All ANLL was observed in patients who had received the mechlorethamine-vincristine-procarbazione-prednisone (MOPP) regimen. No ANLL was documented among 115 patients treated with RT alone, nor among the 109 given CT alone. Leukemia, which developed 34-184 months after diagnosis of HD, was always preceded by a preleukemic phase and was fatal (after 1-12 months) to 13 patients. The karyotype of the leukemia cells was studied in 11 of the 14 patients and was always abnormal. CONCLUSIONS: A Cox's Linear Logistic Model that was performed did not demonstrate that the treatment categories, age, sex, and splenectomy were prognostic factors. Because all ANLL was observed in patients who were treated with extended-field RT plus MOPP and who had undergone splenectomies at diagnosis of HD, further research with larger numbers of patients and longer follow-up should be pursued. Thus with such additional data, clinicians could come to appreciate fully the statistical significance of our interesting observations.

Immunohistochemistry of malignant lymphomas. Advantages and limitations of the new monoclonal antibodies working in paraffin sections.

On the basis of the experience derived from the study of 2,000 biopsies, the authors critically review the problem of the newly generated monoclonal antibodies (mAbs) working in paraffin sections. The reliability and drawbacks of the most commonly used reagents are examined, with special reference to their employment in the diagnosis of malignant lymphomas. The authors underline that only a few mAbs are really specific, since most reagents give rise to a certain number of cross-reactivities. In the light of this, a wide panel of antibodies should always be applied in the diagnosis of lymphoid tumours in order to avoid possible misinterpretations, which can actually lead to wrong therapeutical decisions.

Stage I high-grade non-Hodgkin's lymphomas: a retrospective analysis.

BACKGROUND: The treatment strategy for stage I non-Hodgkin's lymphomas (NHL) is far from being clearly established. METHODS: Thirty-seven patients (pts) with clinical stage I high-grade NHL treated between 1983 and 1989 have been retrospectively reviewed. Nineteen pts were treated by radiotherapy (RT) alone; 14 pts received chemotherapy (CT) followed by adjuvant RT, 3 pts CT alone and 1 pt underwent surgery alone. All pts with bulky disease were submitted to combined therapy. RESULTS: Estimated 7-yr overall survival (OS) was 82%, while freedom from relapse (FFR) was 73%. No differences in OS and FFR were recorded with regard to the type of treatment, site of the tumor, sex or histology. CONCLUSIONS: Our conclusion is that stage I NHL, even with unfavourable histology, may be successfully treated with RT only; however, CT before RT may be recommended in pts with a higher risk of relapse, i.e. the presence of bulky mass.

Accelerated hemopoietic recovery after chemotherapy and autologous bone marrow transplantation in hematological malignancies using recombinant GM-CSF: preliminary results obtained in 14 cases.

Human recombinant granulocyte-macrophage colony-stimulating-factor has been employed, on a compassionate basis, in 14 hematological patients in order to reduce the duration of the neutropenic period after high-dose chemotherapy for the treatment of hematological malignancies (7 traditional CHT courses, 7 autologous bone marrow transplantations). The compound was administered intravenously by 6-hour infusion at a dose of 5 microgram/kg/day until the patient reached at least 1000 PMN in the peripheral blood. Eleven out of the 13 evaluable patients showed a significative improvement in hemopoietic recovery, even though in CHT patients hematological reconstitution was higher in terms of PMN counts. The ABMT patients, however, showed a faster myeloid recovery than that obtained both in a group of 14 NHL and in a series of 8 MM previously submitted to ABMT in our Institution. Moreover the increase in peripheral neutrophils appeared to be stable, since it was maintained throughout one month after the end of rhGM-CSF therapy. We did not observe effects on platelet or erythrocyte recovery. We conclude that rhGM-CSF is active in accelerating the recovery of myelopoiesis, without significant toxic or collateral effects.

A phase III comparative trial of m-BACOD vs m-BNCOD in the treatment of stage II-IV diffuse non-Hodgkin's lymphomas.

From September, 1984 to July, 1986 seventy previously untreated adult patients with advanced non-Hodgkin's lymphoma of intermediate or high grade histology were enrolled in an open phase III multicenter, comparative chemotherapeutic trial. The objectives were to compare, by means of response rate, duration of response and survival time, the efficacy and safety of substituting mitoxantrone for doxorubicin in the combination chemotherapy regimen m-BACOD (methotrexate, bleomycin, doxorubicin, cyclophosphamide, vincristine and dexamethasone). Thirty-five patients were randomly assigned to receive m-B-NOVANTRONE TM (mitoxantrone)-COD (m-BNCOD) and 35 m-B-ADRIAMYCIN TM (doxorubicin)-COD. The complete response rate was 57% for both treatment groups, and no significant disease-free survival and survival differences were found between the two groups of patients. Patients treated with m-BACOD experienced severe alopecia more frequently (p less than 0.001) and, after 10 cycles, six adverse cardiac event of WHO grade greater than 1, as opposed to none among those who received m-BNCOD. The mitoxantrone-containing regimen (m-BNCOD) has equivalent efficacy and reduced toxicity compared to the standard doxorubicin-containing regimen (m-BACOD) in patients with poor prognosis NHL.
