AIDS-related lymphoid neoplasia. The Memorial Hospital experience.

The clinical features and laboratory results of 63 patients with or at risk for AIDS with lymphoid neoplasias seen from November 1980 through November 1986 are reviewed. Forty-three had systemic non-Hodgkin's lymphoma (NHL), nine had primary large cell lymphomas of the brain, 11 had Hodgkin's disease (HD), and one had plasmacytoma evolving to myeloma. Those with systemic NHL included 40 (93%) with intermediate or high-grade histologies, 35 (81%) with advanced stage (III, IV), and 28 (65%) with extranodal disease at presentation (predominantly marrow and meninges). Overall survival was short (median, 10.5 months from diagnosis) with the majority of deaths attributable to AIDS-related opportunistic infections (OI). However, 17 patients with diffuse NHL achieved a complete clinical remission, and nine now have been disease-free for more than 1 year (median follow-up, 28 months; range, 12 to 73 months). Early stage and lack of systemic symptoms were features associated with prolonged disease-free survival. Primary brain NHL was a uniformly lethal manifestation of AIDS, being diagnosed at postmortem in seven of nine severely immunosuppressed homosexual men. As with NHL, a propensity towards advanced disease and extranodal involvement was also observed in HD, suggesting that the atypical clinical behavior of HD may be an additional epiphenomenon of AIDS. This experience tends to argue for the use of intensive therapy in at least some patients with AIDS-related systemic NHL since it has resulted in a proportion of long-term disease-free survivors.

Primary lymphoma of the liver.

Nine adult white men ranging in age from 27 to 76 (mean, 55 years) were treated for primary hepatic lymphoma between 1972 and 1986 at the Memorial Sloan-Kettering Cancer Center. Six patients presented with right upper quadrant or epigastric pain or discomfort, and three patients complained of fatigue and lethargy. Fever and night sweats were evident in two, and two patients had lost weight. One patient was asymptomatic; the liver mass was detected during the work-up for cancer of the prostate. Seven patients on whom computerized tomography was performed all had solitary masses in the liver although in three of them tumor had extended into both lobes as noticed at surgery. One had additional porta hepatic lymph node metastasis. Eight patients underwent an exploratory laparotomy; four had hepatic resection, and four had wedge biopsies of unresectable liver tumor. One patient had a percutaneous needle biopsy of the liver. Eight patients received combination chemotherapy. Six patients are alive, five of whom are in initial complete remission. All three patients who died had persistent or recurrent disease in the liver. The results of therapy and surgery to date in these and in other cases in the literature are encouraging.

Central nervous system metastases from non-Hodgkin's lymphoma: treatment and prophylaxis.

Central nervous system (CNS) lymphoma was identified in 96 patients treated for non-Hodgkin's lymphoma at Memorial Sloan-Kettering Cancer Center between 1975 and 1981. During the same period, 68 other patients with non-Hodgkin's lymphoma but no CNS disease received prophylactic CNS chemotherapy. In the 156 total patients, the lymphomas were diffuse in 96 percent, and 67 percent were stage IV at diagnosis. CNS involvement was present at initial diagnosis in 27 percent, at relapse in 26 percent, and during the course of progressive systemic disease in 47 percent. CNS involvement was asymptomatic in 10 percent. Cytologic study of the cerebrospinal fluid was the most sensitive and specific laboratory test, but often (22 percent) more than one lumbar puncture was required to identify malignant cells. CNS lymphoma was treated in 85 patients, 46 by intracerebroventricular cannulae; 81 percent improved. Although median survival after the diagnosis of CNS disease was four months, there were seven long-term disease-free survivors and the CNS disease contributed to death in only 14 percent. In 52 percent of treated patients, there was no CNS lymphoma at autopsy. CNS prophylaxis was with methotrexate or cytosine arabinoside, usually by lumbar puncture; an intraventricular cannula was used in seven patients. Although this group of high-risk patients with non-Hodgkin's lymphoma had a high systemic response rate and the median projected survival was greater than five years, CNS lymphoma developed in eight patients (12 percent). In five, CNS lymphoma occurred as an apparently isolated relapse site. The role of CNS chemoprophylaxis in high-risk patients with non-Hodgkin's lymphoma is still uncertain.

Generalized lymphadenopathy with morphologic features of Castleman's disease in an HIV-positive man.

In recent years the literature has described a highly lethal "multicentric" variant of classic Castleman's disease (CD) with similar hyperplastic angio-follicular morphologic features. A 44-year-old man who was not known to be part of any established high-risk group for the acquired immune deficiency syndrome (AIDS) presented with clinical and laboratory features similar to "multicentric" CD. Serologic testing revealed antibody to the human immunodeficiency virus (HIV) by Western blot analysis. It is suggested that "multicentric" CD may be part of the clinicopathologic spectrum of HIV infection, and there should be a high index of suspicion for HIV in patients presenting with generalized lymphadenopathy and histopathologic features of CD.

Localized non-Hodgkin's lymphoma of the breast.

Chart review identified 18 patients seen at Memorial Hospital from 1970 to 1984 with primary non-Hodgkin's lymphoma localized to the breast. Sixteen involved the breast alone (Stage IE), whereas two also involved ipsilateral axillary lymph nodes (Stage IIE). None had B symptoms. Histologic subtypes included 11 diffuse histiocytic, 4 diffuse poorly differentiated, 2 diffuse mixed and one nodular mixed. Thirteen patients (72%) are alive with 55 months median follow-up (11 months-14 years). Three patients died with recurrent disease at less than 2 years, one recurred at 4 years and died 6 years after diagnosis, and one died at 30 months without clinical evidence of disease. Seven (39%) have remained continuously disease-free (11 months-11 years; median, 54 months). Of the clinical Stage I patients, 1 of 3 treated with mastectomy alone recurred in the scar, whereas 1 of 12 treated with irradiation alone recurred locally. Thus, radiation therapy alone achieved good local control, although distant relapses remain a problem in these clinically staged patients. Overall, the outcome of clinically localized non-Hodgkin's lymphoma of the breast is similar to that for localized lymphoma in other sites.

Non-Hodgkin's lymphomas: characteristics of long-term survivors following conservative treatment.

A most important set of prognostic factors for survival among 467 patients with non-Hodgkin's lymphoma receiving conservative treatment was determined statistically by the Cox proportional hazards model. Non-Hodgkin's lymphoma was diagnosed in these patients between 1958 and 1969. Initial biopsy material was classified according to the Working Formulation, and the Rappaport, Kiel, and Lukes-Collins systems. The Cox analysis identified a group of 37 patients with a median survival of 150 months. These patients had the following characteristics: small lymphocyte, plasmacytoid lymphocyte, small cleaved, large cleaved or non-cleaved follicular center cell histologic subtype (Lukes-Collins); no bulky involvement of mesenteric nodes or critical organs--kidney, urinary tract, or pleura; stages I to III disease (78 percent stage I or IE); no B symptoms; age below 60 years; initial resection as a reflection of localized disease. Patients with advanced-stage non-Hodgkin's lymphoma receiving conservative treatment have a relatively short survival (median, less than five years) regardless of histologic subtype.

Semen cryopreservation and artificial insemination for Hodgkin's disease.

Seventy-nine men with Hodgkin's disease were treated with chemotherapy protocols at Memorial Sloan-Kettering Cancer Center and had pretreatment semen analysis performed at the area semen bank. The patients were evaluated to determine: the quality of pretreatment semen, the effect of treatment on spermatogenesis, and the success rate of artificial insemination after semen cryopreservation. Pretreatment sperm concentration, fresh motility, fresh progression, postthaw motility and postthaw progression were all significantly decreased in men with Hodgkin's disease compared with normal controls. Posttreatment semen analysis in 44 men showed azoospermia in 80%, sperm concentration, less than or equal to 10 X 10(6)/mL in 11%, and sperm concentration greater than 10 X 10(6)/mL in 9%. Eleven couples attempted artificial insemination using cryopreserved semen, thus far resulting in three pregnancies. Semen cryopreservation and artificial insemination offer a partial solution to posttreatment azoospermia in this population, but further methods are needed to minimize gonadal toxicity without compromising therapy for Hodgkin's disease.

Recent results of multimodal therapy of gastric lymphoma.

The efficacy of multimodality treatment of gastric lymphoma was examined in a retrospective study of 46 patients treated at the Memorial Sloan-Kettering Cancer Center from 1971 to 1982. The principal treatment plan consisted of surgical resection of the gastric lymphoma (n = 36) where feasible, followed by radiation therapy of the whole abdomen (n = 23) with a boosting dose to the stomach-bed to 3700 cGy, and/or chemotherapy using mainly the CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) regimen as an adjuvant (n = 7), or CHOP plus other drugs for advanced disease. The median follow-up time of patients was 61 months (range, 30 months to 14 years). There was no operative mortality. No patient developed known relapse in the abdomen after resection and total abdominal irradiation, and none suffered relapses after adjuvant chemotherapy, for Stages I-E and II-E. At 5 years, the estimated survival rate after treatment was 95%, 78%, and 25%, respectively for Stages I-E (n = 20), II-E (n = 9) and IV (n = 17). The results for Stage I-E and II-E resectable tumors were significantly improved (P less than 0.05 and less than 0.1 respectively) over those of similar tumors treated in 1949 to 1970.

Osteonecrosis in patients with malignant lymphoma. A review of 31 cases.

Osteonecrosis of the femoral and humeral heads is a serious complication of therapy for Hodgkin's disease and non-Hodgkin's lymphoma. Twenty-five patients were reassessed 5 years after being initially reported, in order to study the further progress and natural history of this complication. In addition, six recent patients who have also developed this condition are presented. With 5-year additional follow-up, no patient had developed symptoms of osteonecrosis in any bone other than those initially involved. Five patients developed severe complications thought to arise from their therapy suggesting that this group of patients were more sensitive to radiation injury than other patients treated with this modality. During the relatively short follow-up 5-year period, a surprising finding was the fact that 31% of the patients with Hodgkin's disease and 50% with non-Hodgkin's lymphoma had died. It is recommended that patients treated for lymphoma with steroid containing chemotherapy and radiotherapy be observed carefully for the occurrence of joint pain. Early diagnosis should lead to attempts to prevent total joint destruction.

Evaluation of malignant lymphomas using three classifications and the working formulation. 482 cases with median follow-up of 11.9 years.

Three classifications and the Working Formulation for non-Hodgkin's lymphomas have been studied in 482 patients with a median follow-up of 11.9 years. Each classification was evaluated independently, and their similar and discrepant aspects were analyzed by comparing subgroups in the different schemes. Clinical staging was essential in the evaluation of some categories. There are several differences between the classifications that are not readily reconcilable. The Rappaport classification's principal groups are heterogeneous. Separation of follicular lymphomas into small and large cleaved cell types (Lukes-Collins) is significant. The addition of a follicular mixed cell type (Rappaport, Working Formulation) detracts from this significance. Centrocytic and lymphoplasmacytic tumors (Kiel) are well-defined categories and important in understanding some deficiencies in the other classifications. The small cleaved cell type, diffuse (Lukes-Collins, Working Formulation) is heterogeneous. Diffuse lymphomas of mixed cell types are poorly defined subgroups. Excluding lymphoblastic types, the presence of plasmacytic differentiation is important in identifying the high-grade lymphomas with the poorest prognosis. These results suggest that adjustments should be made in the classifications and in the Working Formulation.

Treatment of stages I and II Hodgkin's disease with three different therapeutic modalities.

Since 1969, 184 previously untreated and evaluable adult patients with Hodgkin's disease, staged as I (43) or II (141), have been treated. Eighty patients were part of the National Hodgkin's Disease Study, randomly assigned to receive radiotherapy to either an involved (39) or extended field (41). In a subsequent single-arm study, 104 patients were treated with involved-field radiotherapy preceded and followed by three cycles of MOPP chemotherapy. Median durations of follow-up have been 172, 172, and 92 months, for the involved-field radiotherapy, extended-field radiotherapy, and MOPP plus involved-field radiotherapy treatment groups, respectively. Although significant differences among the three treatment groups were observed with respect to disease-free survival (p less than 0.001), only the group of patients treated with involved-field radiotherapy had a statistically significant decline in overall survival as compared with the two other treatment groups (p less than 0.001). Moreover, patients who underwent clinical staging and were treated with MOPP plus involved-field radiotherapy had significantly prolonged disease-free survival compared with those who underwent surgical staging and were treated with extended-field radiotherapy (p less than 0.001). One of the patients who received MOPP plus involved-field radiotherapy had subsequent development of acute monocytic leukemia, and another had refractory anemia with excess blasts. One instance of diffuse poorly differentiated lymphocytic lymphoma was also observed. Acute monocytic leukemia developed in another patient treated with involved-field radiotherapy. The rates of amenorrhea in the group treated with MOPP plus involved-field radio-therapy were 9.6 percent and 78.5 percent for female patients younger and older than 30 years of age, respectively. Despite the universal azoospermia ensuing after MOPP plus involved-field radiotherapy, in three patients whose sperm counts were checked sequentially for 26 to 53 months after treatment, evidence of spermatogenesis was observed. Three patients with remission of Hodgkin's disease after involved-field (two) and extended-field (one) radiotherapy died from cardiovascular disease that could only be attributed to the prior radiotherapy. Although further follow-up evaluation will be required to determine the impact of the three different treatment modalities on survival and long-term toxicity, MOPP plus involved-field radiotherapy appears to be superior to involved-field or extended-field radiotherapy alone in achieving prolonged disease-free survival without significant leukemogenic potential.

Long-term follow-up of cardiac function in patients with Hodgkin's disease treated with mediastinal irradiation and combination chemotherapy including doxorubicin.

Among 41 evaluable patients whose first treatment for advanced Hodgkin's disease had consisted of alternating cycles of mechlorethamine, vincristine, prednisone, and procarbazine (MOPP), and doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD), in addition to low-dose mediastinal irradiation, 19 underwent retrospective cardiac evaluation by routine posteroanterior and lateral chest x-ray, 12-lead ECG, M-mode echocardiogram, and ECG-gated left ventricular blood pool scan at rest and during exercise. Fifteen patients had unequivocally normal left ventricular function by all these parameters. Two patients had minimally reduced left ventricular ejection fraction (LVEF) at rest with a normal increment with exercise. In two other patients with high normal resting LVEF and subnormal increment with exercise, the elevated resting values implied initial measurement in a nonbasal state. A twentieth patient (the oldest; one of two with active Hodgkin's disease at the time of evaluation and the stimulus for this study) had markedly reduced LVEF as determined by radionuclide cardiac angiography and had developed clinical congestive heart failure shortly before evaluation. Despite this patient, the study indicates that treatment with MOPP/ABVD and low-dose mediastinal irradiation entails low risk for cardiac complications.

Strategies in the treatment of Hodgkin's disease.

The current treatment methods for the four stages of the four histologic subtypes of Hodgkin's disease are described. In the last several years, the use of radiotherapy and combination chemotherapy has dramatically improved the prognosis of patients with even the most advanced stages of disease. However, toxicity remains a problem. Gonadal function is adversely affected in many patients, and the risk of subsequent acute leukemia or myelodysplastic syndrome is about 10% at 10 years after treatment. There have been few trials of biologic response modifiers in Hodgkin's disease, and the results show no advantage over chemotherapy and radiotherapy. Newer therapeutic approaches will need to be devised, both to reduce toxicity and to improve the response of the relatively small number of patients who do not achieve a durable remission with present treatment.

Value of splenectomy in non-Hodgkin's lymphoma.

A retrospective review of patients with non-Hodgkin's lymphoma (NHL) who underwent palliative splenectomy for splenomegaly, hypersplenism, or autoimmune complications was done. From 1970 through 1981, 46 patients had palliative splenectomy for splenomegaly alone (n = 3) or various hematologic abnormalities with (n = 35) or without (n = 8) splenomegaly. Splenectomy was performed for life-threatening (n = 7), severe (n = 15), or mild (n = 24) symptoms/signs. The most common hematologic abnormalities were thrombocytopenia (platelet count less than 120,000/mm3; n = 38) and/or anemia (hemoglobin level less than 11.0 g/mm3; n = 29). Response to splenectomy was defined as greater than a threefold increase in preoperative platelet count and/or an increase in hemoglobin levels to greater than 11.0 g/mm3 in the first postoperative month. Four patients with thrombocytopenia did not respond, whereas 33 patients responded with greater than a sevenfold increase in platelet count. All four nonresponders died of complications of thrombocytopenia or progressive disease. Eighteen of 28 (64%) patients with anemia responded to splenectomy. Larger spleens (2000 g versus 1410 g; P less than 0.05) and lower platelet counts (42,000 versus 75,000; P less than 0.05) were found in all nonresponding patients. Responders and nonresponders could not be distinguished on the basis of age, sex, race, duration of disease or splenic involvement, primary site of disease, histopathologic findings, bone marrow or lymphangiogram results, or prior chemotherapy and radiotherapy. Patients with mild symptoms/signs were more likely to respond hematologically than patients with life-threatening or severe symptoms/signs (86% versus 54%; P = 0.06). For all patients, 2- and 5-year survival from the time of splenectomy was 44% and 26%, respectively. Median survival was 18 months (range, 1-144 months). Inability to reverse hematologic abnormalities was associated with poor survival. All nonresponding patients died within 36 months of surgery, whereas 5-year survival in responding patients was 40%. Nine of 30 patients (30%) who responded hematologically survived longer than 5 years, but this group of patients could not be distinguished from the remaining patients on the basis of age, sex, race, duration of disease or splenic involvement, primary site of disease, histopathologic features, bone marrow or lymphangiogram results, or prior chemotherapy and radiotherapy. Surgery was well-tolerated (mortality, 9%; morbidity, 21%). All surgical mortalities and 78% of complications occurred in patients operated on for life-threatening or severe symptoms/signs.(ABSTRACT TRUNCATED AT 400 WORDS)

NHL-3 protocol. Six-drug combination chemotherapy for non-Hodgkin's lymphoma.

Combination chemotherapy and radiotherapy (RT) were administered to 73 adults with non-Hodgkin's lymphoma (NHL). Ten cycles of the following drugs were given: intravenous Adriamycin (doxorubicin) (25 mg/m2), cyclophosphamide (700 mg/m2) and vincristine (1.5 mg/m2) on day 1; arabinosylcytosine (100 mg/m2) and methotrexate (10 mg/m2) on days 3 to 5; and oral prednisone (60 mg/m2) on days 1 to 5. Radiotherapy was given to resistant or initially bulky disease (2000 rad). Patients were also randomized to receive pseudomonas vaccine or no immunotherapy. Of 61 evaluable patients, 33 (54%) achieved a complete response (CR) and 18 (30%) a partial response (PR). Among 44 evaluable patients with diffuse histiocytic lymphoma (DHL), 22 (50%) had a CR, and 15 (34%) a PR. For 17 evaluable patients with nodular (4) and diffuse (11) mixed and poorly differentiated lymphocytic and diffuse "undifferentiated" (2) lymphomas, CR and PR rates were 65% and 18%, respectively. No statistically significant differences in response rate or duration and survival have been observed between the patients randomized to receive pseudomonas vaccine or no immunotherapy. Median follow-up time from start of treatment was 47.5 months. Median survival for all 73 patients (including inevaluables ) and for 52 DHL patients was 30.7 months. Poor prognostic features influencing survival included: female sex (P = 0.003), poor response to therapy (CR versus PR; P = 0.001), prior chemotherapy, (P = 0.01) and high levels of lactic dehydrogenase (P = 0.001). It can be concluded that this combination of cycle and phase-active agents is of similar efficacy to other reported regimens in inducing major responses and that it has the potential to prolong disease-free survival. The analysis of prognostic factors has been used to dissect poor prognostic categories that might require different modalities of treatment.

Treatment of advanced Hodgkin's disease with chemotherapy and irradiation. Controlled trial of two versus three alternating, potentially non-cross-resistant drug combinations.

From January 1979 to June 1983, 71 evaluable, previously untreated patients with advanced Hodgkin's disease completed a randomized trial of two or three potentially non-cross-resistant drug combinations and low-dose radiotherapy to initially involved nodal regions (2,000 to 3,000 rads). All patients received nine cycles of alternating chemotherapy regimens and radiotherapy between cycles 6 and 7. Thirty-four patients received three combinations: lomustine, melphalan, vindesine (CAD), MOPP, and doxorubicin, bleomycin, vinblastine (ABV). The complete remission rate was 82 percent, partial remission rate 12 percent, and progression rate 6 percent. There were two relapses from complete remission and three deaths. Thirty-seven patients received MOPP and ABV plus dacarbazine (D). The complete remission rate was 78 percent, partial remission rate 16 percent, and progression rate 6 percent, with three relapses from complete remission and five deaths. Myelosuppression was more frequent with CAD/MOPP/ABV/radiotherapy, and nausea and vomiting with MOPP/ABVD/radiotherapy. The results for both are among the best reported, and CAD/MOPP/ABV/radiotherapy was more acceptable to patients.

Treatment of patients with advanced malignant lymphoma using gallium nitrate administered as a seven-day continuous infusion.

Previous trials of gallium nitrate (NSC-15200) showed that bolus administration produced dose-limiting nephrotoxicity without substantial antitumor activity. As an effort to increase the therapeutic index of this compound and to establish a satisfactory out-patient schedule, the authors evaluated the effects of gallium nitrate administered as a continuous infusion in patients with advanced malignant lymphoma. In an initial Phase I trial, four dose levels which ranged from 200 to 400 mg/m2/day in 27 patients were studied. Nausea which impaired oral hydration was found to be dose-limiting. A dose of 300 mg/m2/day was chosen for extended Phase II evaluation and 37 additional patients were entered into the study at that dose level. Overall, 16 of 47 patients (34%) who had bi-dimensionally measurable parameters of disease achieved major antitumor responses (six of 15 with diffuse "histiocytic" lymphoma, five of ten with diffuse poorly-differentiated lymphocytic lymphoma, two of five with nodular poorly-differentiated lymphocytic lymphoma, and three of 17 with Hodgkin's disease). The median duration of response was 2.5 months. Only 8% of patients who received 300 mg/m2/day developed an increase in serum creatinine concentration greater than 1.1 mg/dl over baseline values. Hypocalcemia occurred in two-thirds of patients. Other toxic effects, including paresthesiae, diarrhea, and hearing loss, were noted in less than 5% of patients. There was minimal myelosuppression. The authors conclude that gallium nitrate administered as a continuous infusion for seven days at 300 mg/m2/day is well-tolerated and effective treatment for patients with advanced malignant lymphoma. Outpatient administration using portable infusion pumps is safe and practical. Further evaluation of the drug administered as a constant infusion is indicated in patients with other neoplastic diseases.
