The prognosis for patients with AML is improving, but mortality due to bleeding and infection remains significant. HLA compatibility has been the cornerstone of matching for prophylactic platelet transfusion; while HLA matched platelets are often of benefit, we have observed that HLA matching does not reliably predict transfusion responses. The platelet migration inhibition assay is, however, consistently predictive. The matching problem may be circumvented by the use of frozen autologous platelets, which circulate and function hemostatically. In the granulocytopenic patient with de novo fever (frequently due to bacterial sepsis), the immediate empiric use of broad spectrum antibiotics is mandatory. If the marrow begins to recover from chemotherapy shortly after the onset of infection, such that the peripheral granulocyte count will approach normal within 10 days, the likelihood of survival from an episode of septicemia after antibiosis now approaches 80%. If the marrow does not recover shortly, however, the likelihood of survival with antibiosis alone is poor. In this setting, survival is improved if patients are given granulocyte transfusions in addition to antibiotics. Patients who receive chemotherapy in a laminar air-flow room (LAFR) experience fewer severe infections than do patients in a conventional ward. However, most patients who are unresponsive to initial chemotherapy remain so in spite of protection from infection. Thus, the available results do not suggest that the LAFR is likely to improve appreciably the rate or duration of remission. Using malignant lymphoma as a model, we have found that cryopreserved autologous marrow infusions can hasten hematopoietic recovery in man after high-dose chemotherapy, and earlier reconstitution may be of clinical benefit to the patient; techniques are at hand that might permit the application of this concept to AML.

Review of the coagulation laboratory records and medical records at Memorial Sloan-Kettering Cancer Center over a three year period (1971--1974) revealed 89 patients with disseminated intravascular coagulation (DIC). The diagnosis of DIC was made if laboratory studies showed evidence of quantitative and qualitative changes in fibrinogen and significant thrombocytopenia. The patients included 19 with leukemia (17 acute), 3 with multiple myeloma, 15 with lymphoma, 46 with metastatic solid tumors, (10 lung, 9 breast, 8 gastrointestinal, 12 genitourinary, 7 miscellaneous) 4 with vascular tumors, and 3 without tumor. Other conditions which might have precipitated or initiated DIC such as gram-negative sepsis, liver impairment, or mucin secreting tumors were present in the majority of patients. Bleeding occurred in 75% of the patients and was fatal in 36%. Thromboembolism occurred in 22.5%. Thirteen percent were asymptomatic. Serum lactic dehydrogenase was elevated in over 75% of the patients at the time of, or subsequent to the occurrence of DIC. Treatment with heparin was helpful in only three of twenty patients. Eighty percent of the patients died within one to over 30 days of the onset of DIC. Post mortem evidence of DIC was present in 18 of 43 autopsies. Results of this study indicate that DIC is a frequent complication of a wide variety of tumors and that its occurrence causes morbidity and mortality in a significant number of patients. Treatment with heparin is of little help unless remission is induced and the precipitating factor(s) are reversed.

The 18-year-old white male developed acute myeloblastic leukemia (AML) 25 months after diagnosis of poorly differentiated lymphocytic lymphoma, diffuse pattern (PDLL-D), involving cervical, supraclavicular, and mediastinal lymph nodes as well as bone marrow. Treatment of the lymphoma consisted of 2,000 rads to the mantel area and 18 months of chemotherapy with intravenous (IV) methotrexate (400 mg/m2), vincristine, and prednisone, alternating every two weeks with IV cyclophosphamide (1,000 mg/m2), vincristine, and prednisone plus monthly intrathecal methotrexate. Thereafter, a complete remission was maintained without therapy until the onset of AML. Several pseudodiploid clones containing multiple structural rearrangements and a hypodiploid clone were identified in the circulating blood at the time of diagnosis of AML. Induction therapy consisting of cytosine arabinoside, 5-azacytidine, vincristine, and prednisone was unsuccessful, and the patient died of sepsis two months after diagnosis. This case calls attention to the increased risk for subsequent acute nonlymphocytic leukemia in patients previously treated for nonhodgkin lymphoma.

The five-year experience with 75 consecutive splenectomies has been reviewed. Special detail was given to eight critically ill hypersplenic patients. Their diagnoses included Hodgkin's disease, lymphoma, leukemia, myelofibrosis and Felty's syndrome. Three presented with sepsis, two with anemia not responsive to transfusion, three had pathologic bleeding and two could not receive additional needed therapy of underlying disease because of low counts. All cases responded to splenectomy favorably. Hypersplenism is primarily a loss of balance between the splenic destruction-sequestration and bone marrow production. The demonstrated rapid consumption of transfused cells and some degree of functional reserve of the bone marrow is the prerequisite and clue for splenectomy response in critically ill patients.

Twenty patients with several histologic subtypes of non-Hodgkin lymphoma who had become resistant to combination chemotherapy were treated with a five-day course of the epipodophyllotixin VP-16. Of 19 evaluable patients, 8 (42%) responded to treatment with 1 complete response and 7 partial responses. The median duration of response was 5.5 months. Seven of the responders had a diffuse lymphoma and 1 had a nodular lymphoma. Of the responders who had diffuse histiocytic lymphoma (DHL), diffuse mixed lymphoma (DML), and diffuse undifferentiated lymphoma (DUL)--the more aggressive histologies in the Rappaport classification--6 of 13 (46%) evaluable patients responded to therapy. Responses were seen in node-dominant, skin-dominant, and marrow-dominant disease. Toxicity was mainly hematopoietic, 53% of patients experiencing leukopenia ( less than 2,000 cells per cu mm) and 68% of patients experiencing thrombocytopenian 2,000 cells per cu mm) and 68% of patients experiencing thrombocytopenia ( less than 100,000 platelets per cu mm). There were two deaths attributable to profound leukopenia with sepsis. The activity of VP-16 in patients who have previously been extensively treated with multiple drugs including vincristine supports its activity in the lymphomas and suggests its lack of cross-resistance with vincristine. The inclusion of VP-16 in primary treatment protocols in the diffuse lymphomas should be considered.

During a 14 month period there were 364 episodes of bacteremia and fungemia at Memorial Sloan-Kettering Cancer Center. The first nine months of the study were retrospective, and the next five prospective. In patients with leukemia or lymphoma (group 1), Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Staphylococcus aureus were the most frequently isolated organisms. The mortality in this group was 40.5 per cent. In the patients with solid tumor (group 2), Esch. coli, Staph. aureus, Bacteroides sp. and Candida sp. were most frequent. Mortality was 27.8 per cent. The source of infection in both groups was often indeterminate. High mortality was associated with pulmonary and intraabdominal infection and with Ps. aeruginosa, K. pneumoniae or polymicrobic sepsis. Factors of prognostic significance were the causative microorganism, source of infection and shock. Although mortality was higher in patients with leukopenia than in those with normal leukocyte counts, the differences were not significant. The mortality in this series was low considering the severity of the underlying diseases and the immunosuppressed state of many of the patients. In a prospective, randomly controlled study, mortality was further diminished by infectious disease consultation at the time the positive blood culture was reported. Severe fungal superinfection, predominantly aspergillosis and candidiasis, was found in 52 per cent of the autopsy patients with leukemia or lymphoma (group 1), but in only 8 per cent of those with solid tumors (group 2).

Fifteen patients with a rare malignant lymphoma characterized by a high content of epithelioid histiocytes are reported. This lymphoma, referred to as "Lennert's lymphoma," was originally thought to be a variant of Hodgkin's disease, but has both histologic and clinical differences. Although the infiltrate is polymorphous, diagnostic Reed-Sternberg cells are difficult to find and involvement of tonsils relatively common. Lennert's lymphoma bears some resemblance to immunoblastic lymphadenopathy in that some patients have a history of allergies, polyclonal hyperglobulinemia, and all lymph nodes demonstrate variable proliferation of immunoblasts. However, both vascular proliferation and the amorphous eosinophilic interstitial material characteristic of immunoblastic lymphadenopathy are lacking. The clinical course in this series was unpredictable with rapid death in six cases, chiefly from sepsis, 1--18 months following diagnosis despite therapy as for Hodgkin's disease. The remaining eight patients for whom follow-up data are available are in apparent clinical remission. Further cases and investigations are needed to determine the precise behavior of Lennert's lymphoma and to learn its exact status in relation to other malignant lymphomas or immunoblastic proliferations.

Twelve patients with acute or chronic pneumonia due mainly to gram-negative bacilli, two patients with pseudomonas endocarditis, and two patients with seratia sepsis were treated with 80-160 mg of tobramycin in two daily doses. Fourteen infected patients with underlying leukemia or lymphoma received this dose of tobramycin combined with cefazolin or penicillin. Most respiratory infections were cured or markedly improved. with eradication or significant reduction in the number of infecting organisms. One case of pseudomonas endocarditis and both cases of serratia sepsis were also cured. Combined treatment with tobramycin and beta-lactam antibiotics resulted in clinical and bacteriological improvement in 50% of systemic immunodepressed patients with sepsis and/or pneumonia.

Report of a T-cell rich B-cell lymphoma (TCRBCL) in a 43 years old man with an associated haemophagocytic syndrome (HS). At presentation the haemophagocytic cells involved the same organs as the lymphoma, i.e. spleen, liver, abdominal lymph nodes and bone marrow. As supportive measure to alleviate chemotherapy-induced granulocytopenia the cytokine granulocyte-macrophage colony-stimulating factor (GM-CSF) was given. After an initial improvement of the blood granulocyte count pancytopenia developed again, resulting in fatal sepsis. Autopsy demonstrated massive proliferation of macrophages in the bone marrow with haemophagocytosis as morphological correlation to the pancytopenia. The observation that exogenous GM-CSF enhanced the preexistent HS primarily reactive to the TCRBCL raises the question if endogenous GM-CSF may play a role in triggering a HS. The observed association of TCRBCL and HS has not been reported so far.

Although early survival following transplantation for primary hepatic cancer is excellent, previously reported high recurrence rates have generally discouraged liver replacement for this indication. Since the inception of the Boston Center for Liver Transplantation (BCLT) in 1983, 33 of 383 (8.6%) liver allograft recipients have undergone orthotopic transplantation as definitive treatment for otherwise unresectable cancer. Diagnoses included hepatocellular carcinoma (HCCA) in 24 patients (73%), and cholangiocarcinoma (CHCA) in 9 patients (27%). Actuarial survival rates for patients with hepatocellular carcinoma were 71%, 56%, and 42% at 1, 2, and 3 years, respectively. The actuarial survival rates for patients with cholangiocarcinoma were 89% at 6 months, and 56% at 1, 2, and 3 years. Of the nine patients with cholangiocarcinoma, 56% (5/9) developed recurrent disease. Although this recurrence rate is disheartening, because of the lack of other morbidity, long-term survival in these patients is comparable to patients with HCCA. In contrast, recurrent hepatocellular carcinoma developed in 25% of recipients (5/20) who survived longer than 3 months posttransplantation. Other causes of death in patients with hepatocellular carcinoma included perioperative complications, 16.6% (4/24); sepsis, 8.3% (2/24); coronary artery disease, 4.2% (1/24); and lymphoma, 4.2% (1/24). Favorable prognostic factors included: primary tumor less than 3 cm in size and absence of associated cirrhosis. These results emphasize that orthotopic liver transplantation can provide a long-term cure for approximately 50% of patients whose primary hepatic malignancy is unresectable by conventional procedures.
