The value of staging in malignant lymphomas is underscored by the advances made in therapeutic options. Through the years, it has become clear that combined modality therapy should be avoided if possible because of the increased risk of second malignant diseases. Thus, it is crucial to define those patients who are potentially cured by limited therapy, such as radiotherapy alone, or combination chemotherapy. This means that careful clinical staging with the best roentgenographic techniques currently available is necessary. At institutions, such as the University of Chicago and Stanford University, it is important to determine nodal disease that is potentially cured with radiotherapy (I through III, III1, at the University of Chicago). In non-Hodgkin's lymphoma, such as poorly differentiated lymphoma and diffuse histiocytic lymphoma, only a small percentage of patients in certain centers who have truly localized Stage I disease may benefit from radiotherapy alone. It is these groups of patients who may need surgical staging. Thus, in 1986, only a small percentage of patients with non-Hodgkin's lymphoma will actually benefit in terms of therapeutic options from the staging laparotomy. Perhaps as newer imaging techniques, such as magnetic resonance imaging, become available, the staging laparotomy may become obsolete.

Malignant lymphomas of the testis account for approximately 5 percent of testicular neoplasms, and they are the most common testicular malignancy between the ages of 60 and 80. Testicular lymphoma has a propensity to be associated with involvement of the skin, the central nervous system, Waldeyer's ring and adjacent structures, and the contralateral testicle. In general, essentially all patients with testicular lymphoma have been categorized as having "poor-risk" non-Hodgkin's lymphoma, with diffuse histiocytic lymphoma being the most common histologic subtype. All patients with testicular lymphoma should be treated with aggressive combination chemotherapy, with or without radiotherapy.

Data from four clinical trials conducted by the Eastern Cooperative Oncology Group (ECOG) were used to investigate the importance of bone marrow involvement as a prognostic factor in patients with non-Hodgkin's lymphoma (NHL). A total of 502 patients, 275 with nodular, poorly differentiated lymphocytic lymphoma (NLPD) and 227 with diffuse histiocytic lymphoma (DHL) or diffuse mixed-cell lymphoma (DML), were included in this analysis. Patients were separated into four categories: stage III, stage IV with bone marrow involvement (stage IV-M), stage IV without marrow involvement (stage IV-O), and stage IV with bone marrow and other organ involvement (stage IV-OM). Among the DHL and DML patients, the incidence of marrow involvement was 23%. However, stage IV-M patients had a prognosis that is similar to stage IV-O and stage IV-OM and worse than stage III patients. In contrast, the incidence of involvement with NLPD was 59% and patients with stage IV-M had a survival not different than stage III and not worse than stage IV-O and stage IV-OM. The results suggest that the current emphasis on bone marrow biopsy(s) as a routine diagnostic staging procedure for patients with NHL should be reevaluated. The necessity for this procedure in stage III patients with NLPD is not apparent from our data. One can still justify a bone marrow biopsy in stage I and II patients and can confirm the complete clinical response when all nodes have regressed in more advanced disease.

The biologic and clinical heterogeneity of the various subtypes of non-Hodgkin's lymphoma is related to differences in morphologic, immunologic, and kinetic properties. Comprehensive studies characterizing these features in lymphomatous effusion have yet to be reported. We recently studied 27 effusion specimens from 26 patients with clinically suspected or confirmed lymphoma. Wright-Giemsa- and Papanicolaou-stained cytologic preparations, acridine orange nucleic acid flow cytometry, and immunoperoxidase staining of cell suspensions using antibodies to a battery of T and B cell markers were evaluated and compared with prior histologic accessions. Specimens were classified by cytologic characteristics according to the International Working Formulation Scheme and by acridine orange nucleic acid flow cytometry using the parameters of DNA, RNA, and proliferative activity. Correlation of the cytometric and morphologic data demonstrated that with increasing cytologic grade of lymphoma, the proliferative activity increased progressively and distinguished between grades (P less than 0.01). Immunologic studies identified B cell phenotype in 16 specimens, T cell in three, and true histiocytic lymphoma in one; one lymphoma had no cell markers (null cell). Six effusions proved to be inflammatory and reactive according to surface marker studies. Classification by cytologic characteristics showed good correlation with histologic classification performed previously. Immunologic study of cytologic specimens gave results identical to those achieved by frozen-section immunohistologic examination. Thus, immunologic and cytometric parameters can be readily performed on effusion specimens and aid in the diagnosis and classification of lymphomas.

Fifty-six patients with advanced non-Hodgkin's lymphoma (NHL) were entered into a phase II study of prednimustine, an ester of chlorambucil and prednisolone. All patients were refractory to extensive prior combination chemotherapy. Therapy with prednimustine, 100 mg/m2/day orally, was given for three consecutive days every 2 weeks. The overall response rate in 43 evaluable patients was 30% (13/43), with 9% (4/43) achieving complete response (CR) and 21% (9/43) achieving partial response (PR). In the favorable histology subgroup (23 patients), the response rate was 39% (9/23), with 4% (1/23) achieving CR and 35% (8/23) achieving PR. In the unfavorable histology subgroup (20 patients), responses were seen in 20% (4/20) with 15% (3/20) achieving CR, all in heavily pretreated diffuse histiocytic lymphoma. Toxicity of this regimen was mild, with leukopenia below 3,000/mm3 in 22% and thrombocytopenia below 90,000/mm3 in 16% of patients. A positive correlation was observed between response and hematologic toxicity, indicating the potential for a dose-escalation schedule in future trials. These data confirm activity of prednimustine in NHL refractory to standard treatment. In view of its relatively mild toxicity, we conclude that prednimustine is an appropriate agent to test in combination chemotherapy regimens in this group of lymphomas.

Primary lymphoma of bone is an unusual extranodal presentation of pediatric non-Hodgkin's lymphoma (NHL). Treatment with radiotherapy alone has resulted in a disease-free survival rate of approximately 50% in most adult series. Between January 1973 and April 1985, 11 children with biopsy-proven NHL of bone were seen and treated at our institutions. The minimal clinical staging included chest and bone radiographs, a radionuclide bone scan, complete blood cell counts and serum chemistries, and a bone marrow aspirate and biopsy. The age range was 9 to 17 years with a median age of 14 years. Histology included diffuse lymphoblastic lymphoma in four patients and diffuse histiocytic lymphoma in seven. Each patient was treated with the Adriamycin/prednisone/Oncovin (APO) protocol and ten patients received concomitant radiation to the whole bone when possible and a boost to the primary lesion(s). The median tumor dose was 5,000 rad (range, 3,600 to 5,600). The median follow-up was 8 years. There have been no relapses, but two patients have developed second bone tumors 5 and 7 1/2 years after beginning therapy. Each second tumor arose directly in the radiation field. The overall 8-year actuarial survival is 83%. We conclude that APO and local radiation results in excellent overall survival for children with primary NHL of bone. The occurrence of two second bone tumors, however, raises questions regarding dose and/or the role of radiation for this disease.

A retrospective analysis was performed of 238 patients, aged 12 years and older, with non-Hodgkin's lymphoma presenting to the All India Institute of Medical Sciences, New Delhi, India, between September 1975 and December 1982. Pathologic material was reviewed and classified according to the modified Rappaport classification. The most common histologic type encountered was diffuse histiocytic lymphoma (39%), followed by diffuse poorly differentiated lymphocytic lymphoma (29%), and diffuse mixed histiocytic and lymphocytic lymphoma (9%). Nodular lymphomas constituted 9% of all non-Hodgkin's lymphomas. A lower frequency of nodular lymphomas, a lower median age of onset (45 years), and a higher male to female ratio (4.5:1) as compared with Western countries was observed. Survival information on 90 patients revealed no effect of age, sex, stage of disease, and "B" symptoms on survival, whereas histologic diagnosis had a significant influence on survival (P less than 0.05). A median survival of 24 months in 58 patients receiving chemotherapy is comparable to that reported by other investigators.

In 2 randomised, prospective Eastern Co-operative Oncology Group trials, the frequency of central nervous system (CNS) involvement after chemotherapy in 347 adults with stage III and IV unfavourable-histology, non-Hodgkin's lymphoma was 8.4%. The frequency varied from 0% in diffuse mixed lymphoma to greater than 30% in lymphoblastic and diffuse-undifferentiated lymphoma. Of the 42% of patients who achieved complete remission after chemotherapy, CNS involvement developed in 5.4% during relapse, but in only 2.7% was the CNS the sole site of relapse. CNS lymphoma arose in 6.6% of 197 patients with diffuse histiocytic lymphoma, but in only 1 subject (1%) was the CNS the sole site of relapse. Therefore, CNS prophylaxis is not indicated for the common diffuse-histology subtypes of adult non-Hodgkin's lymphoma including diffuse-histiocytic, diffuse-mixed and diffuse poorly differentiated lymphocytic lymphoma. The relatively high frequency of CNS lymphoma in lymphoblastic and diffuse undifferentiated lymphoma justify further studies of CNS prophylaxis.

Thirty-eight pretreated patients with Hodgkin's disease (HD) and malignant non-Hodgkin's lymphoma were given combination chemotherapy with VM-26, Adriamycin, bleomycin, and prednisone. Four of 15 evaluable patients with HD achieved a partial remission (PR), with a median duration of 8 months. Of 12 patients with diffuse poorly differentiated lymphocytic lymphoma, one achieved a complete remission (30+ months) and five achieved a PR (median, 6 months). One of three patients with histiocytic lymphoma had a PR of 1.5 months. There was one drug-related death. Five patients developed life-threatening hematologic toxicity. Two HD responders died of acute nonlymphocytic leukemia.

Follow-up data for 11 patients with non-Hodgkin's lymphoma treated with partially purified human leukocyte interferon is presented. The interferon preparation used was 0.1% pure and treatment consisted of 5 x 10(6) U given intramuscularly twice daily for 60 injections. One complete, three partial, and three minimal responses were observed in five of seven evaluable patients with nodular non-Hodgkin's lymphoma. Duration of response appears to be from 6 to 12 mo. One patient achieved a second partial response on retreatment with interferon in spite of having received chemotherapy in the interval between interferon treatments. No responses were seen in three patients with rapidly progressive diffuse histiocytic lymphoma. Dose-limiting toxicity is leukopenia, which necessitated modification or cessation of treatment in three patients. Nonhematologic toxicities consisted of fever, malaise, arthralgia, and loss of appetite. In conclusion, interferon has activity against non-Hodgkin's lymphoma, and prior treatment with chemotherapy does not preclude a response to interferon.
