Twenty Malaysian patients with unresectable primary liver cell cancer were prospectively studied at the General Hospital, Kuala Lampur, and were compared for clinical features with an equal number each of African and American patients being studied by the Eastern Cooperative Oncology Group. The patients received intravenous 5-FU and oral MeCCNU which was used for the first time in an Asian country. Most of the Malaysian patients were Chinese, belonged to younger age groups, and presented with massive hepatomegaly, jaundice, and fever. Toxicity to MeCCNU invariably occurred in the form of leukopenia or thrombocytopenia, but none life threatening. Partial response was seen in 20% of Malaysians as compared to 16% in Americans and none in Africans. Malaysians achieved a median survival of 16 weeks compared to 28 weeks in Americans and only eight weeks in Africans. Malaysian Chinese patients were all HBc Ab + ve. Other factors which may have played an etiologic role in the induction of primary liver cancer included alcohol, Chinese herbal medicines, aflatoxin and habitual use of medicated rubbing oils.

Neocarzinostatin (NCZ), a new antitumor antibiotic, was administered to 19 patients with bladder cancer, 16 patients with prostatic cancer, and 3 patients with hepatoma. All patients had objectively measurable metastatic lesions including 21 with palpable nodes or subcutaneous nodules, 10 with pulmonary nodules as demonstrated by chest x-ray, 4 with malignant hepatomegaly, and 3 with bidimensional pelvic masses as demonstrated by CT scanning. Sixty-five courses of NCZ were administered via an intravenous bolus daily for five days with dosages ranging from 1500 to 3000 U/m2. Immediate toxicity was not dose-limiting except for 1 episode of anaphylaxis and 1 of acute renal failure. Myelotoxicity was delayed, dose-dependent, noncumulative, and dose-limiting. Thrombocytopenia was prolonged or irreversible in 5 cases. The maximally tolerated dose was 2750 U/m2. One patient with NCZ-associated pulmonary fibrosis and 1 with biopsy-proven hepatitis are discussed in detail. Neocarzinostatin demonstrated minimal therapeutic activity (1 partial remission) in patients with bladder cancer. There was no response in patients with prostatic cancer or hepatoma.

In previous studies, the prognostic value of bone marrow (BM) histologic patterns in chronic lymphocytic leukemia (CLL) has been demonstrated. In order to investigate whether such a value is independent of other prognostic parameters, a multivariate survival analysis (Cox's regression model) was undertaken in a series of 329 CLL patients in whom a BM had been performed. The following binary variables were included in the analysis: age (more than 60 years), lymphadenopathy (more than two areas involved), splenomegaly, hepatomegaly, absolute lymphocyte count (more than 30,000 microL), anemia (hemoglobin less than 10 g/dL), thrombocytopenia (less than 100,000 microL), and BM pattern (diffuse v nondiffuse). Three variables entered the regression at significant level: BM pattern (P less than .001), anemia (P less than .001), and hepatomegaly (P = .03). The model was also tested by expressing the variables in a continuous way when possible. Again, BM pattern entered first in the regression (P less than .001), followed by the hepatomegaly (P = .002), hemoglobin level (P = .02), and lymphadenopathy (P = .04). When both the binary and the continuous models were tested separately in 227 patients with BM as initial staging procedure and in 102 patients in whom this was performed later during the course of the disease, in all instances, BM pattern entered first in the regression at a highly significant level. BM histologic pattern appears to be a better single prognostic parameter than any one of the variables employed in current clinical staging systems. A combined clinicopathologic system incorporating the BM pattern, together with the usual clinical variables, is presented.

Three patients developed blastic transformation of essential thrombocythemia (tET). Morphological studies in all patients showed that the majority of blasts had either myeloblastic or myelomonoblastic differentiation. Immunologic assays of hematopoietic cells were performed in two patients. In patient 1, 86% of peripheral blood mononuclear cells (predominantly blasts) reacted with a monoclonal antibody specific for granulocytes and monocytes (MMA), and 15% of mononuclear cells reacted with Tab, a monoclonal antibody specific for megakaryocyte-platelet glycoproteins (PGP) IIb and IIIa. In patient 2, 41.5% of peripheral blood mononuclear cells (predominantly blasts) were MMA-positive, 22.5% were Tab-positive, and 40% reacted with rabbit anti-human PGP. These results suggest either that two subpopulations of blast cells exist in tET, or that blast cells simultaneously express surface markers of myeloblastic/monoblastic and megakaryoblastic differentiation. In these three and in nine previously reported cases of tET, neither age, sex, nor previous therapy were obvious etiologic factors. tET occurred 24.2 +/- 14.4 mo after diagnosis of essential thrombocythemia, and a majority of patients had hepatomegaly and/or splenomegaly, anemia, leukocytosis, and thrombocytopenia. Leukemic cell morphology was myeloblastic and/or monoblastic in 12/12 patients, 5/12 had marrow fibrosis. Despite various treatments, death occurred in 3.6 +/- 2.7 mo; one patient had a brief complete remission.

An 18-year-old patient at 15 weeks' gestation was hospitalized for a high fever and delirium secondary to a presumed viral syndrome. She had massive hepatomegaly, and a small breast lump was noted incidentally. Abnormalities in the differential blood count and liver function tests were found in addition to thrombocytopenia. Bone marrow biopsy revealed metastatic breast cancer.

Three children developed acute veno-occlusive disease of the liver following combination chemotherapy for acute myelocytic leukemia. The clinical presentation was similar in all three, with acute onset of hepatomegaly and thrombocytopenia in the absence of significant transaminasemia or icterus. In all three patients, radionuclide imaging with technetium-99m sulfur colloid showed hepatosplenomegaly, decreased liver uptake, and increased splenic activity. The results of liver biopsy established the diagnosis, revealing marked centrilobular congestion with hemorrhage into the spaces of Disse, atrophy of central hepatic cords, and edema of the walls of the central and sublobular veins. Each patient showed marked improvement following temporary cessation of chemotherapy. The diagnosis of veno-occlusive disease is suggested by the triad of: (1) clinical signs and symptoms; (2) scintigraphic findings; and (3) temporal relationship to chemotherapy.

The case of a patient with ecchymosis, hepatomegaly, leukocytosis, thrombocytopenia, and anemia at birth is presented. Throughout his course, thrombocytopenia, anemia, and leukocytosis without a marked increase in the number of blast forms in either peripheral blood or bone marrow persisted until the patient developed a blast crisis shortly before his death at age 4 months. This patient is the youngest reported to have the juvenile form of chronic myelogenous leukemia and the first that in the present era can be considered congenital in origin.

The clinical and hematologic characteristics of 38 children with subacute and chronic myelomonocytic leukemia (S & CMMOL) are described, and the prognostic significance of these characteristics as recorded at diagnosis is reported. The common and distinctive feature of these children was the excessive proliferation of cells of neutrophilic and monocytic series. The disease predominated in younger children, 95% were younger than 4 years, and boys were more affected than girls (22/16). The onset of the disease was heralded most often by acute or subacute symptoms. Splenomegaly was the most common physical finding at diagnosis. Leukocytosis was usually under 100 X 10(9)/l. Monocytosis and granulocytosis were often associated with normoblastosis, and, in some cases, with moderate blastosis (less than or equal to 30%). Severe anemia and marked thrombocytopenia were found in about one third of patients, increased fetal hemoglobin levels in 53%, and increased gamma-globulin levels in 50% of cases. The Philadelphia chromosome was absent in all blood and marrow cell karyotypes. Thirty-three of 38 patients were treated with moderate or intensive chemotherapy, and in all cases treatment never resulted in a complete remission. Terminal acute leukemia occurred in 11 cases. Of the 38 patients, 29 have died (median survival time, 16 months). Initial characteristics predicting a short survival (log-rank test) included: older age (greater than or equal to 2 years) (P less than 0.001), hepatomegaly (P less than 0.05), bleeding (P less than 0.001), thrombocytopenia (P less than 0.01), high counts of blasts and normoblasts in peripheral blood (P less than 0.01, P less than 0.01). Sex, infections, cutaneous manifestations, lymphadenopathy, degree of splenomegaly, hemoglobin levels, fetal hemoglobin, leukocyte counts, percent of blasts in bone marrow, and serum gamma-globulin levels were of no prognostic value. When survival was plotted on a semilogarithmic scale, a change in death rate was evident at the second year of survival suggesting that there may be two subgroups of patients with myelomonocytic picture, one with very rapid, and another with a slower rate of mortality. A stepwise discriminant-function analysis was performed in an attempt to distinguish between those children who lived less than or equal to 2 years and those who lived longer. A linear combination of variables which best discriminated between these two subgroups was found. Nearly all patients could be classified as a short-survivor or long-survivor on the basis of age and platelet, blast, and normoblast counts in peripheral blood.(ABSTRACT TRUNCATED AT 400 WORDS)

Infantile hepatic hemangioendothelioma is a rare tumor of infancy, sometimes associated with cutaneous hemangiomatosis. It is clinically evident within the first six months after birth and can be life threatening because of heart failure, intraperitoneal hemorrhage or thrombocytopenia. In less severe forms spontaneous regression has been described. Current treatment may be surgical ligation of the hepatic artery, or pharmacological therapy with corticosteroids or radiotherapy. A 4-month infant is described, admitted with acute heart failure and huge hepatomegaly. Since a surgical approach was not possible and corticosteroid therapy failed to achieve the expected effect, radiotherapy was given with excellent results.

From 1972 to 1981 10 patients with hairy cell leukaemia were observed in the Medical University Clinic Cologne, this represents 1.8% of all leukaemias. Typical clinical signs are splenomegaly, no or only slightly enlarged lymph nodes and a moderate hepatomegaly. Almost in all cases an anaemia, thrombocytopenia and neutropenia with lymphocytosis was found, mostly combined as pancytopenia. The pathognomonic tartrate resistant acid phosphatase was found in the hairy cells to a differing amount besides a fibrosis and a lymphatic infiltration of the bone marrow. A normalization of the anaemia, the thrombocytopenia and the neutropenia was reached by splenectomy, but the increased susceptibility to infections could not be affected significantly.
