Lymphoid neoplasia is a complex area comprising multiple diseases with varied pathology, treatment, and outcome. The non-Hodgkin's lymphomas are reviewed here. Non-Hodgkin's lymphomas, collectively, represent the sixth most common cancer in the United States as well as the sixth most common cause of cancer deaths. The overall incidence of non-Hodgkin's lymphoma has risen steadily over the past four decades. Although some of this is attributable to human immunodeficiency virus (HIV)-associated lymphoma, HIV-associated disease accounts for only a small part of the increase in lymphoma. As our knowledge of normal as well as neoplastic lymphoid development has expanded on the basis of histopathology as well as adjunct cellular and molecular techniques, multiple classifications have been proposed to take these into account. The clinical relevance to our understanding of non-Hodgkin's lymphoma is the concept that various lymphoid cancers are counterparts of stages of normal lymphoid development. Stages of lymphoid development in terms of cell surface markers and immunoglobulin gene rearrangements have been well characterized. These are particularly applicable to the early B-cell development, which is antigen-independent and occurs in the bone marrow. Diseases correlating with these stages are largely acute lymphocytic and lymphoblastic leukemia/lymphoma and high-grade lymphomas, such as Burkitt's lymphomas. Much has been learned recently about subsequent antigen-dependent B-cell development in secondary lymphoid organs to improve our understanding of the corresponding stages of B-cell neoplasia. Many of these stages correlate with more recently described entities such as mantle cell and marginal zone lymphomas. Histologic study remains crucial in determining the subtype of NHLs, whereas immunohistochemistry, surface phenotype, and molecular studies are useful in selected cases. Although some lymphoma classifications may be better in terms of understanding the lymphoma biology, the working formulation remains useful to guide clinical decision making. Lymphomas classified as low grade are considered incurable with standard therapy when diagnosed, as is usual, at advanced stages. Different subtypes may have different median survivals, but the goal has typically been palliation, whereas experimental approaches are clearly needed. Intermediate and high-grade lymphomas are potentially curable with aggressive combination chemotherapy. Recent evidence suggests that CHOP chemotherapy is as effective as more complex regimens. Still, 40% to 50% of patients are cured. Prognostic factor analysis has allowed separation of subgroups with much better survival in whom CHOP is adequate versus those with much poorer survival in whom experimental approaches are rational. Additional subtypes of lymphomas have been described and characterized since the working formulation was developed, including mucosa-associated lymphoid tissue tumors (MALT-oma), mantle zone lymphoma, anaplastic large cell lymphoma and AILD-like T-cell lymphoma. Approaches to these entities are still being optimized. Newer approaches, including high-dose therapy with stem cell support, biologic agents, and newer chemotherapeutic agents are discussed, as are special situations such as localized lymphoma of certain sites and lymphoma in immunosuppressed patients.

A case of synchronous malignancy of oesophagus with Non Hodgkin's lymphoma is presented and the rarity of such an association is discussed. The inherent difficulties encountered were initial planning of therapy keeping in view of the general condition of the patient. The patient received three cycles (every 21 days) of CHOP regimen for Non Hodgkin's lymphoma and to maintain a static state of oesophageal cancer. The patient showed more than 75 percent response to NHL counterpart, and for carcinoma oesophagus counterpart short course high dose loco-regional radiation therapy was given and the tumor was found to be resectable.

Data of 38 patients with primary tonsil lymphoma, treated during the past 14 years was analysed. All cases were non-Hodgkin lymphomas. There were 11 patients with Stage 1, 14 with Stage II, 8 with Stage III, and 4 with Stage IV tonsillar lymphomas. The applied chemotherapies were CHOP or MACOP-B regimen. The overall 5-year survival rate was 64.4%. Further analysis of the intermediate grade group showed that 5-year survival rates were 72.7%) for patients younger than 60 years old, in contrast to 35.0% for patients aged 60 or older (p 0.0049). Five-year survival rates were 100%) for Stage I, 32.4% for Stage II, 55.6% for Stage III, and 100%) for Stage IV patients (p = 0.0878). In patients with Stage II tonsillar lymphomas, 5-year survival rates were below 100% for CHOP regimen, 100% for MACOP-B regimen, 66.7% for radiation alone, and 0% for radiation followed by chemotherapy (p = 0.1966). In patients with Stage III tonsillar lymphomas, 5-year survival rates were below 100% for MACOP-B regimen, and 0% for initial radiation followed by chemotherapy (p = 0.2568). The factors influencing survival were age, stage, and treatment modality. For Stage I patients without bulky mass, radiation therapy is sufficient. For Stage II patients or Stage I patients with a bulky mass, CHOP regimen (followed by radiation) is the choice of treatment. For Stage III or IV patients,, MACOP-B regimen is promising.

Non-Hodgkin-lymphoma (NHL)-most frequently high grade B-cell lymphoma-occurs in 5-10% of individuals with HIV-infection. The gastrointestinal tract (GIT) is the most frequent extranodal site of the disease. The optimal therapy for HIV-related lymphoma remains a matter of controversy. In a retrospective analysis we found gastrointestinal lymphoma in ten of 306 HIV-infected patients (3.3%) with a median CD4-count of 92/microliter at time of diagnosis. Median survival for the chemotherapy treatment group was 15 months. The high incidence of gastrointestinal NHL prompted us to commence a prospective survey on diagnostic procedures, therapy and outcome of patients with HIV-infection and gastrointestinal symptoms. 93 of 341 HIV-infected patients with gastrointestinal symptoms were examined by endoscopy. In selected patients we used in addition endoscopic ultrasound (EUS) for visualization and staging before and after chemotherapy. NHL of the GIT was detected in seven of 93 endoscopically examined patients (7.5%). All patients were treated with CHOP initially. Mean survival time was ten months, mean CD4-count at diagnosis 193/microliter (range 0-417). Our results indicate that the diagnosis of gastrointestinal lymphoma should be considered in any HIV-infected patient presenting with unexplained gastrointestinal symptoms. In this group of patients NHL was detected in 7.5% of cases. The use of EUS improves the staging procedure before therapy. Treatment with CHOP resulted in relatively high remission rates and was associated with a low rate of treatment-induced myelosuppression.

CD30(Ki-1) positive anaplastic large cell lymphoma (ALCL) is a distinct entity, in which the monoclonal antibody-positivity against the CD30(Ki-1) antigen of tumour cells has a diagnostic value. The histological subtypes of ALCL show also certain clinical differences. Except for some pediatric cases and cutaneous forms clinical outcome is very unfavourable despite of the various treatment methods. In this prospective study (follow-up of 11-60, median 16 months) clinicopathological data and treatment results of fifteen adult patients with ALCL were analysed, Mean age was 46 (16-69) ys with a bimodal tendency and a distinct female: male ratio (3:2) was observed. Early clinical stages (I-II/A-B, eight patients) dominated, and two main groups could be distinguished histologically (Hodgkin-related, ALCL-HR and common type, -CT in eight and seven patients), respectively. In all histological specimens CD30 antigen expression was detected. Additional immunophenotyping was performed in five cases (two 0-variant, two of B-cell and one of T-cell origin), respectively. A bulky disease, mainly in the mediastinum was observed in six cases, and a primary gastrointestinal localization in two other patients. In the treatment of these high grade malignant lymphomas a combination of cobalt irradiation and aggressive chemotherapy was applied (in elder the CHOP-regimen, in younger patients mainly the Pro-MACE-Cyta-BOM-protocol). In one relapsed younger patient autologous bone marrow transplantation was also performed. A complete or partial remission was achieved in thirteen patients (86.6%) but six patients expired after only a short response period to therapy. Overall survival was 19, whilst disease-free survival revealed to be 15 months. Eight of their living nine patients have a durable complete remission. Due to residual mediastinal mass after radiotherapy in three cases a permanent radiological follow-up is needed. Advanced age and clinical stages are considered to be unfavourable, whilst histological subtypes were indifferent prognostic factors, as well. Favourable results in therapy and durable complete remission in younger patients are probably caused by the their better tolerance of third-line aggressive chemotherapy.

Therapy for aggressive non-Hodgkin's lymphomas has undergone significant evolution in the past 25 years. First-generation combination chemotherapy studies produced complete response (CR) rates of 45-53% together with 30-37% rates of long-term survival. New treatment programs aimed at increasing CR rates were then developed on the assumption that the additional patients who achieved a CR would become long-term disease-free survivors. Initial reports of single-institution pilot studies with third-generation regimens suggested CR and survival rates of 68-86% and 58-69%, respectively; however, after longer follow-up-periods, survival rates decreased. Furthermore, confirmatory national phase II trials using these newer regimens produced CR rates of only 49-65% and survival rates of 50-61%. Thus, ultimate conclusions concerning the efficacy of these new regimens awaited the results of prospective randomized trials. The Southwest Oncology Group (SWOG) conducted a randomized trial comparing standard therapy. CHOP, to the third-generation chemotherapy regimens m-BACOD, ProMACE-CytaBOM, and MACOP-B. After 6 years, on difference in the response rate, progression-free survival, or overall survival has been found between CHOP and third-generation regimens. For example, the 6-year estimates of progression-free survival are CHOP 33%, m-BACOD 36%, ProMACE-CytaBOM 34%, and MACOP-B 32% (P = 0.41). The 6-year overall survival estimates are CHOP 42%, m-BACOD 40%, ProMACE-CytaBOM 46%, and MACOP-B 41% (P = 0.89). Furthermore, we have not identified any subset of patients who survive longer on treatment with the third-generation regimens, and the cost and toxicity of the new regimens are higher. On the basis that < 50% of these patients are cured, the best approach for any patient is an experimental one designed to improve our ability to cure the disease. Examples of this include (1) increasing the dose intensity of drugs used in standard regimens and (2) autologous bone marrow transplantation and/or peripheral stem-cell support as rescue from marrow-ablative chemotherapy. If a patient is not eligible or does not wish to participate in a clinical trial, CHOP, as inadequate as it is, remains the gold standard.

Several clinical trials have demonstrated that high-dose chemotherapy (HDC) with autologous hematopoietic stem-cell transplantation is more effective than conventional-dose chemotherapy in some subsets of patients with malignant lymphoma, such as relapsed aggressive lymphoma patients showing a response to salvage chemotherapy and those with Hodgkin's disease who fail primary initial chemotherapy. This paper summarizes recent findings and the following issues remaining to be resolved: (1) whether HDC is superior to conventional-dose chemotherapy as initial therapy for aggressive lymphoma in unfavorable risk groups, (2) whether single HDC or multiple semi-HDC is better, (3) whether HDC has curative potential in indolent lymphoma or mantle-cell lymphoma, and (4) the HDC regimen that is most useful. To clarify these controversial issues, well-designed clinical trials are needed. To evaluate whether the concept "the more chemotherapy, the better in malignant lymphoma" is valid, the Lymphoma Study Group of the Japan Clinical Oncology Group is conducting two kinds of clinical trials in high- and high-intermediate-risk aggressive lymphoma patients, focusing on the dose intensity of key agents. One is a randomized phase II trial of dose-escalated cyclophosphamide, doxorubicin, vincristine, and prednisolone (high CHOP) versus shortened CHOP (biweekly CHOP) with prophylactic use of granulocyte colony-stimulating factor. The other is a phase II trial of HDC with peripheral blood stem-cell transplantation as a part of the initial therapy. If promising results are obtained from these trials a randomized phase III trial will be considered to compare the best dose-intensive regimen with standard CHOP.

Seventy-six patients with stage I or IE intermediate-grade or immunoblastic non-Hodgkin's lymphoma were treated with a short course of doxorubicin-containing chemotherapy with (n = 58) or without (n = 18) involved field radiotherapy. Chemotherapy consisted of 3 or 4 cycles of M-BACOD or (bleo-)CHOP. Seventy-two (97%) of the 74 evaluable patients achieved a complete response. The 3-year overall survival was 89%, recurrence-free survival 94%, and lymphoma-specific survival 93%. Patients older than 60 years also had a 3-year lymphoma-specific survival rate of as high as 92%. The International Prognostic Index was associated with overall survival (p = 0.04), but not with lymphoma-specific survival (p = 0.18). We conclude that stages I and IE intermediate-grade or immunoblastic non-Hodgkin's Hodgkin's lymphoma is highly curable if treated with short doxorubicin-containing chemotherapy and involved field radiotherapy.

Approximately one-fourth of non-Hodgkin's lymphomas originate in extranodal sites. True primary involvement of soft tissues is quite uncommon and only a few well-documented cases are reported in the literature. We report four cases of primary skeletal muscle lymphoma. Three of the four cases presented with a diffuse large B-cell lymphoma. The clinical history of two cases confirmed that soft tissue masses should be promptly biopsied, since the differential diagnosis comprises benign lesions, as well as sarcoma, primary or metastatic carcinoma, melanoma and lymphoma. As lymphomas have to be treated primarily according to the tumour histology and disease extent, treatment of primary skeletal muscle lymphomas must be planned with these factors in mind. For patients presenting with diffuse large cell histology, a CHOP-like regimen alone or a combined modality with radiotherapy seem to be proper approaches.

Lymphomas belong to the class of malignant diseases with the fastest increasing incidence. High-grade non-Hodgkin's lymphomas (NHL) display a peak of incidence in the age group above 65. In the last few years, age has been recognized as a major risk factor for overall survival of high-grade NHL patients, and numerous attempts have been made to analyze the contribution of factors to the age-related worsening of prognosis in this disease, e.g. the biology of the disease on the one hand, and age-specific comorbidity or degree of cytotoxicity, reluctance in diagnosis and treatment and socioeconomic factors on the other. Furthermore, age-adapted treatment protocols have been designed and tested for their practicability and efficacy in the elderly. Very recently, large randomized prospective clinical trials have been carried out which support the idea that treatment with a curative intent is warranted even in the very elderly and that a successful attempt to cure requires the use of full-dose anthracycline-containing regimens closely similar to CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone). In addition, progress has been made in systematically defining maximally tolerated doses of the cytotoxic drugs and in specifically testing anthracyclines with reduced cardiotoxicity with an efficacy similar to that of doxorubicin, and further in investigating the advantage of applying hematopoietic growth factors and/or cardioprotective drugs in this older population. In limited stages of disease, three cycles of CHOP chemotherapy followed by involved field irradiation may be superior to radiotherapy and prolonged chemotherapy and may produce highly satisfying cure rates.
