Thirty-seven patients with advanced Hodgkin's disease have been treated for greater than or equal to 3 months with a protocol consisting of alternate monthly courses of MOPP (mechlorethamine, Oncovin [vincristine], procarbazine, and prednisone) and ABDV (adriamycin, bleomycin, DTIC, and vinblastine) with local radiotherapy (RT) to areas of originally bulky disease. This therapy produced CR in 19 of 19 previously untreated patients (100%), eight of nine previously treated with RT (89%), and six of nine previously treated with RT and MOPP (67%). The remaining patients are all PRs tending toward CR status. The median time to CR was 3.0 months. The median time in remission to date for the previously untreated patients is 8+ months (2+-14+). After an induction period of eight cycles of chemotherapy patients are maintained on alternate-month treatment continuing the alternating sequence. During this phase three patients have experienced reappearance of disease (one recurrence, one possible second primary lymphoma, and one recurrence in a patient whose original diagnosis is in doubt). The regimen has been well tolerated. All patients were treated as outpatients. Alopecia and neurotoxicity were mild and myelosuppression was moderate. Clinically significant cardiopulmonary toxicity has been limited to mild radiation pneumonitis in one patient and bleomycin pneumonitis which cleared during prednisone in a second patient.

Prospective studies demonstrated variable phenotypic expression of the X-linked recessive lymphoproliferative syndrome (X.L.R.L.S.) in three brothers: (1) hypogammaglobulinaemia and subclinical Epstein-Barr-virus (E.B.V.) infection with antibody response to E.B.V.; (2) E.B.V. infection with defective immune response to E.B.V., fatal infectious mononucleosis (I.M.), and immunoblastic lymphoma; and (3) histiocytic lymphoma. Hypogammaglobulinaemia and measles pneumonitis had preceded infection with E.B.V. The diverse phenotypic expressions probably resulted from the varied immune response to E.B.V. Recombination of X chromosomes was documented by Xg-blood-group studies in a survivor. E.B.V. can induce fatal I.M. and malignant lymphoma in X.L.R.L.S., but an immune response to E.B.V. can be protective.

The air bronchogram classically signals an end-air-space or "alveolar" filling process such as alveolar proteinosis and bronchioloalveolar-cell carcinoma. However, it can also occur in interstitial diseases, possibly leading to compressive atelectasis and causing crowding of tissue around open airways. In addition, such disease processes may encroach on distal airways, producing obstructive pneumonia which may then surround open proximal airways, as in sarcoidosis and lymphoma. In mixed "alveolar" and interstitial processes such as Pneumocystis carinii pneumonia and the late stages of hemosiderosis, "alveolar" filling may mask the interstitial disease.

Six patients with severe herpesvirus infections were successfully treated with vidarabine. One patient had a previously undescribed syndrome of chronic cutaneous varicella infection of eight months' duration, associated with transient but complete duppression of lymphocyte response to conconavalin A. Other diagnoses were severe varicella pneumonia, progressive cytomegalovirus pneumonia associated with acute lymphocytic leukemia, herpes simplex encephalitis, severe zoster associated with stage IV lymphoma, and disseminated herpes simplex in a patient receiving high doses of steroids. All patients showed cessation of new lesions or abrupt clinical improvement between days 2 and 4 after initiation of therapy, and all were cured of their clinical infection. Dramatic improvement in all of our patients and the minimal toxicity observed make vidarabine suitable for use in severe herpesvirus infections.

The authors describe a patient with malignant lymphoma in whom the use of a 67Ga citrate lung scan assisted in the diagnosis of P. carinii pneumonia. In immunodeficient patients presenting with unexplained fever, abnormal pulmonary function tests, a normal chest radiograph, and few chest symptoms, the 67Ga citrate scan may lead to the early detection and successful treatment of this potentially lethal infection.

Five patients had opportunistic pulmonary infection caused by acid-fast bacilli, unusual clinical presentations and a unique pathological picture. Clinically, these cases mimicked septic pulmonary emboli or bacterial pneumonia. The infection was temporally related to high-dose corticosteroid therapy, given for renal-transplant rejection in four patients and for therapy of lymphocytic lymphoma in one. Histologic sections of lung-biopsy or autopsy material showed an acute suppurative pneumonia with dense alveolar infiltration by neutrophils, without granuloma formation or caseous necrosis. Predominantly intracellular acid-fast bacilli were present. The organism failed to grow in culture on routine bacterial, fungal and mycobacterial mediums. This unusual and possibly new acid-fast organism is a probable cause of suppurative pneumonia in impaired hosts receiving corticosteroid therapy.

Over a two year period, we studied prospectively 80 cases of diffuse pneumonia at Memorial Sloan-Kettering Cancer Center. In 72 per cent of these, the patient had leukemia or lymphoma. Diagnostic procedures consisted of extensive serologic testing for antibody to known respiratory pathogens, including the agent of Legionnaire's disease, and culturing of biopsy specimens for bacteria, viruses, mycoplasmas and fungi. Of 44 cases in which open lung biopsy was performed, a specific cause was found in 61.4 per cent: Pneumocystis carinii in 38.6 per cent, other infections in 9.1 per cent and tumor involvement in 13.7 per cent. There were nonspecific pulmonary changes in 38.6 per cent. Of the 56 cases in which biopsy, autopsy or both were performed, a specific diagnosis was made in 69.7 per cent: P. carinii infection in 37.5 per cent and other infections in 12.5 per cent. In cases in which neither biopsy nor autopsy was performed, a specific infection was diagnosed in 33 per cent; no specific diagnosis was made in the remainder. One patient in the entire group had a significant antibody titer for Legionnaire's disease. Although diagnostic in some cases, extensive serologic testing proved relatively unfruitful. Pneumocystosis was the most frequent diagnosis in this study. The cause of some cases remained obscure, even after lung biopsy.

To study the effects of upper mantle radiation therapy on pulmonary function, forced expiratory volume in one second (FEV1), vital capacity (VC), inspiratory capacity (IC), diffusing capacity for CO (DLCO) and diffusion per unit of alveolar volume (DL/VA were determined in 28 patients with Hodgkin's disease, stages 1--3, before therapy and at regular intervals thereafter. Within the first year of follow-up there were significant declines in DLCO, VC, and IC, whereas there were no significant changes in FEV1 or DL/VA. DLCO showed the greatest decline in the largest number of subjects (22/28). Eleven of the 22 had 20 to 60 percent decline of DLCO from baseline. The maximum mean decline in DLCO was -12.7 +/- 3 percent at the 87th +/- 3 days from initiation of therapy postradiation sustained through the 150th day and improving to pretreatment value (+/- 5 percent) by the 8th to 12th month. The changes in DLCO seemed to be independent of the radiation dose ranges evaluated, clinically apparent intrathoracic lymphoma, postradiation radiographic abnormalities and respiratory symptoms. We concluded that impairment in diffusing capacity and loss of vital capacity will develop in most patients receiving upper mantle radiation therapy, indicating that pulmonary reaction occurs despite lung shielding. The functional losses were prolonged and occasionally severe, but were transient and subclinical in most but not all cases. A case of fatal radiation pneumonitis affecting the lung beyond the field of irradiation is reported.

Gallium uptake in a mediastinal mass has been most often seen with lymphoma. A case is reported of thymic uptake in an otherwise healthy 4 1/2 year old boy who had recently had pneumonia. Serial films always showed an unchanging prominent though normal thymus and follow up gallium scans showed disappearance of thymic uptake. This and other similar cases indicate the need to consider a non-neoplastic thymus when gallium accumulation is noted in the anterior mediastinum of a child.

Pulmonary aspergillosis in patients with leukemia or lymphoma is usually a fatal infection. However, difficulty in obtaining a premortem diagnosis has often prevented an adequate trial of anti-fungal chemotherapy. In this report, nine cases of aspergillus pneumonia in patients with hematologic malignancy were diagnosed during a one-year period. Five of nine patients had a premortem diagnosis (56%) and eight of nine (89%) received a premortem trial of amphotericin B. Two of nine patients survived infection, including one patient with prolonged neutropenia. Better diagnostic methods and wider use of antifungal chemotherapy may improve prognosis for aspergillus infection in patients with hematologic malignancy.
