Abstract
Of the 36 patients with human immunodeficiency virus (HIV) infection admitted to our institution since 1985, one had a non-spinal psoas abscess due to Mycobacterium tuberculosis without pulmonary involvement. A 32-year-old male homosexual had prolonged fever and weight loss for two months. Serologic tests for antibodies against HIV were positive. A characteristic hypodense lesion within the right psoas muscle was noted by computerized tomographic (CT) scanning. Diagnosis of psoas abscess was confirmed by ultrasound-guided needle aspiration. The smear of the aspirated pus showed numerous acid-fast bacilli and cultures grew M. tuberculosis. The lesion responded rapidly to antituberculous therapy and a follow-up CT scan 10 months later showed improvement.

Abstract
The molecular characterization of hemophilia A of Chinese origin was carried out by the polymerase chain reaction (PCR) and direct sequencing of patients' factor VIII genes. Single-strand conformation polymorphism (SSCP) and dideoxy fingerprinting (ddF) were used as screening methods to detect mutated DNAs. A total of 102 individuals from 87 different families, including 10 patients (10 families) with mild-to-moderate and 92 patients (77 families) with severe hemophilia A, were analyzed by PCR-SSCP and PCR-ddF. Of the 87 independent cases, 40 revealed a single mutation in the coding regions of their factor VIII genes. These mutations include 21 with single base changes resulting in 8 nonsense and 13 missense codons, 16 with deletion or insertion of 1-11 nucleotides, and 3 with deletion of large DNA fragments. The frequency of 8 of the identified factor VIII polymorphisms or silent mutations was also determined among Chinese. The frequencies for codons 1241, 1269, and 2223 (the numbering system follows J. Gitschier et al., 1984, Nature 312: 326-330) were found to be different from those reported for other populations. As for the 47 severe cases whose mutational events were not readily detected by PCR-SSCP and PCR-ddF, the reverse transcriptase PCR method was applied. In 24 such cases analyzed, 17 were found to be of the "intron 22 mutations" as described by Naylor et al. (1992, The Lancet, 342: 1066-1067), accounting for 39% of Chinese patients with hemophilia A.

Abstract
Analysis of clinical and biologic features of chronic myeloid leukemia (CML) in blast crisis (BC) was performed on 36 patients: 25 had myeloid and 11 had lymphoid transformation. The median duration from diagnosis to onset of BC was significantly shorter in patients with lymphoid BC (6 months) than in those with myeloid BC (41 months). Patients in lymphoid transformation showed better response to therapy and had a significantly longer median survival time after BC than patients with myeloid transformation (56% vs 0% and 10 months vs 4 months, respectively). The leukemic cells from all the patients with lymphoid BC showed B-cell immunophenotype, confirmed by the presence of immunoglobulin (Ig) heavy chain gene rearrangements in the five patients studied. Two of the eight patients with complete marker study expressed myeloid-associated antigens on the blasts. A high incidence of CD7 expression (7/17 or 41%) was found in patients with myeloid BC, but none of the patients who had DNA analysis showed rearrangement of T-cell receptor beta chain gene. Chromosomal abnormalities +8, +19, +21, and i(17q) were detected only in the patients with myeloid BC but not in those with lymphoid BC. Combined analysis of the patients in this series and those reported previously has revealed a statistically significant difference in the distribution of bcr breakpoints between myeloid and lymphoid BC: the bcr breakpoints in more than half of the patients with myeloid crisis were mapped to Zone 2 while those in patients with lymphoid crisis occurred most frequently in Zone 3.

Abstract
The clinical and biologic characteristics of acute myeloid leukemia (AML) with coexpression of lymphoid-associated antigens (Lym+ AML) were studied from 39 cases who represented 24% of 161 newly diagnosed de novo AML. Twenty-seven cases (16.8%) were positive for the expression of T-cell markers (T+ AML) and 12 (7.5%) for B-cell markers (B+ AML). Chromosomal abnormalities t(9;22)(q34;q11) and t/del(11)(q23), which were considered to be associated with acute leukemia coexpressing markers of more than one cell lineage, were detected in five and in four patients, respectively. There was no prognostic significance of B-cell or T-cell antigen expression in AML. Of 12 T+ AML cases in which cells were available for gene analysis, all showed germline configuration of immunoglobulin heavy chain and T-cell receptor beta chain genes, while seven of nine B+ AML showed rearrangements of either or both of the genes. Double labeling of the cells with myeloperoxidase and lymphoid markers demonstrated that individual blasts in all the five T+ AML tested were simultaneously expressing myeloperoxidase activity and CD7; however, most blasts in the three B+ AML studied expressed either myeloperoxidase activity or CD10, but not both. In eight of the nine T+ AML tested, the T-cell antigen-positive leukemic blasts were significantly decreased to less than 10%, after in vitro culture with the differentiation-inducing agent phorbol ester. B-cell markers remained positive (> or = 20%) on the cells in the two B+ AML who had the same study. These findings suggested that T+ AML and B+ AML might have different biologic features. Further studies on more patients are needed to clarify this point.

Abstract
We have characterized the genetic defects of 17 hemophilia B patients of Chinese origin by means of the polymerase chain reaction (PCR) and direct sequencing. The single-strand conformation polymorphism (SSCP) was used as an initial screening method to analyze the entire coding region and the flanking introns of each individual's factor IX gene. The abnormal exons were subsequently amplified and the nucleotide sequence determined. Of the 17 patients studied, 16 had single point mutations and one had a gross gene deletion of exons VII and VIII of factor IX. Among these 16 factor IX variants with point mutations 13 were missense and two were nonsense mutations. The remaining one had a nucleotide deleted, resulting in frame shifting at amino acid residue 97. A total of ten novel mutations, including the one with gross gene deletion, are reported in this study which have not been described previously. Five of the remaining seven variants were missense mutations with novel amino acids substituted for residues 127, 132, 180, 207, and 215, respectively. Mutations containing different amino acid residues at those positions have been reported. The last two are variants that have already been described to contain mutations at amino acid residues 333 and 365, respectively. To evaluate the efficiency of SSCP analysis in assessing the mutated exons and to further confirm our results we sequenced the entire exons of all 17 factor IX genes. The mutations detected by SSCP method were indeed the only mutation identified in each factor IX variant.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Desmopressin (DDAVP) 0.3 micrograms/kg was administered intravenously to three normal volunteers and 12 patients with von Willebrand's disease (vWD), congenital or acquired platelet function defect, or uremic bleeding to assess its effects and side effects. DDAVP significantly shortened the bleeding time as compared with basal values. The mean peak post-DDAVP level of factor VIII coagulant activity increased 5.9 +/- 0.5 (mean +/- SEM) fold, von Willebrand factor antigen increased 3.7 +/- 0.3 fold, von Willebrand factor ristocetin cofactor activity increased 4.6 +/- 0.6 fold and the tissue-type plasminogen activator antigen increased 3.4 +/- 0.6 fold. Analysis of the multimeric structure of the von Willebrand factor revealed that type I vWD had complete correction after DDAVP infusion transiently. Except for a mild drop in both systolic and diastolic blood pressures, few side effects were noted. By concomitant intravenous infusion of DDAVP and oral administration of tranexamic acid, we successfully treated two cases of type I vWD undergoing tooth extraction, and one case of acquired bleeding disorder undergoing a biopsy of a mandibular mass, and a uremic patient complicated by intractable traumatic hematuria. Our experiences confirmed that most patients with vWD and some patients with congenital or acquired bleeding disorders can be treated effectively by DDAVP infusion without the need for plasma product replacement. In this study we found that a patient with a variant form of type I vWD had prolongation of the bleeding time, thrombocytopenia and platelet aggregation after DDAVP infusion.

Abstract
Philadelphia chromosome (Ph') was detected at presentation in 10 out of 110 patients with acute lymphoblastic leukemia (ALL) and five of 168 patients with acute myelogenous leukemia (AML). Two other ALL patients who had studies at relapse were also included in the analyses. One of the 12 Ph'-positive (Ph+) ALL patients had simultaneous expression of myeloid-associated antigen on the leukemic blasts, while all the five AML patients coexpressed markers of lymphoid cells. Double labeling of the cells with myeloperoxidase and CD10 on three Ph+ AML cases showed that most leukemic blasts expressed either myeloperoxidase activity or CD10 but not both. Cross-lineage gene rearrangements of T-cell receptor (TCR) beta-chain gene were detected in three of the eight Ph+ ALL patients tested. All the four Ph+ AML cases studied showed immunoglobulin heavy chain gene rearrangements, and three of them also had simultaneous rearrangements of TCR beta-chain gene. The results revealed that Ph+ acute leukemia in this study belonged either to ALL or mixed lineage leukemia, and none was pure AML. This finding is contrary to that of acute blast crisis of chronic myelogenous leukemia in which the majority of patients had myeloid transformation. Rearrangements of bcr were detected in four of the 10 Ph+ ALL and three of the four Ph+ AML patients tested. No significant difference was noted in the clinical or hematologic manifestations among Ph+ leukemia with or without bcr rearrangements.

Abstract
Among 72 Chinese patients with acute lymphoblastic leukemia (ALL), 50 had clonal chromosomal abnormalities. Structural abnormalities were detected in 42 patients: these included t(9;22) in 9, t(1;19) in 6, t(4;11) in 5, del(11)(q23) in 4, and del(6q) in 4. Adults had a higher incidence of t(9;22) and t(1;19) but a lower incidence of t(4;11) and hyperdiploid greater than 50 karyotype than children. A significant difference was also noted in white blood cell (WBC) count among various karyotypic groups. Patients with chromosomal abnormalities t(9;22), t(1;19), t(4;11) and del(11) (q23) had a shorter complete remission duration as compared with patients free of these abnormalities. Immunophenotyping was performed on 69 patients. All patients with t(9;22), t(1;19), and t(4;11) had B-lineage ALL restricted to certain stages of maturation: groups III and IV, groups IV and V, and group II, respectively (according to the classification of Foon and Tood). Among patients with t(9;22), t(4;11), and del(11)(q23), which have been considered to be associated with acute mixed-lineage leukemia, one each, respectively, showed myeloid antigen expression on the leukemic blasts (My+ ALL). No cross-lineage rearrangements of immunoglobulin (Ig) or T-cell receptor (TCR) genes were detected in these karyotypic subgroups of patients who underwent gene analysis.

Abstract
Hodgkin's disease (HD) is uncommon in Taiwan. In reviewing the clinicopathologic features of 50 cases, the authors found that the diagnosis of HD was complicated with non-Hodgkin's lymphoma (NHL). Fourteen cases were reclassified as NHL containing Reed-Sternberg (RS) giant cells, mostly peripheral T-cell lymphoma (PTL), and 34 cases as classic HD, which included 8 cases of lymphocyte predominance, 10 of nodular sclerosis, 12 of mixed cellularity, and 4 of lymphocyte depletion. For cases of HD, there was a bimodal age-incidence distribution with peaks at the third and fifth decades; 61.8% manifested Stage B symptoms and 80.6% had Stage III/IV disease. The group of patients with NHL, compared with those with classic HD, was found to be older (mean age, 41.4 years versus 33.1 years; P less than 0.05), to have more extranodal disease (35.7% versus 8.8%, P less than 0.05), less complete remission rate (25% versus 67.9%, P less than 0.05), and shorter median survival (29 months versus 90 months). Most of the NHL patients originally were diagnosed as having atypical or unclassified HD. Thus, the authors conclude that the previous observation of a predominance of mixed cellularity HD in Asian regions may be attributable to the inclusion of PTL, which may mimic HD in histology. Because there is a marked difference in clinical behavior and prognosis, it is important to distinguish between HD and NHL containing RS giant cells in an area with a high incidence of PTL.

Abstract
To define the precise genetic defects of hemophilia B of Chinese origin, we have used the polymerase chain reaction (PCR) combined with direct sequencing to analyze the amplified DNA fragments containing the entire coding regions and their flanking introns of the factor IX gene from 6 affected individuals. Among these patients, two are siblings with normal factor IX antigen level (CRM+) yet reduced factor IX clotting activity (28%). Analysis of their factor IX genes revealed a G to A transition at nucleotide residue 10394, which causes substitution of an arginine for a glycine at amino acid residue 48. This is a novel mutation which resides in the first EGF-like domain of factor IX. Studies of two other hemophilia B patients with CRMr phenotypes (factor IX antigen level less than 35%, and clotting activity less than 1%), demonstrated a distinct mutation in each individual's factor IX gene. In one case, a guanine to adenine (residue 6365) transition results in replacement of arginine by glutamine at the -4 codon of the propeptide of factor IX. In the other, thymine at 6442 was mutated to cytosine which causes an arginine for cysteine substitution at residue 23. We have also characterized 2 discrete CRM- patients. Both exhibited an identical mutation at nucleotide residue 6460 which generates a translation termination codon (CGA to TGA) at the 29th amino acid. The mutation created a new NlaIII restriction enzyme site which could be used to identify this variant.

Abstract
In an attempt to evaluate possible variations in the antinuclear antibody (ANA) titers resulting from nuclear substrate difference, we measured the ANA titer of 104 normal subjects using substrates from mouse liver cell (MLC) and HEp-2 cell (CSI, USA). We also performed similar experiments on 50 sera from 50 patients with rheumatic disease using mouse liver cell, HEp-2 cell (CSI), HEp-2 cell (AFT, Japan), and HEp-2 cell (AI, USA) as substrates. The ANA titer assay using HEp-2 cell (CSI), which is routinely used in our laboratory, was regarded as the reference method. The results showed that when HEp-2 (CSI) was used, 98.1% normal subjects had ANA titer lower than 1:320, therefore a cut-off value of 1:320 was used. While using the MLC method, 96.2% normal subjects had ANA titer lower than 1:80, and the cut-off value was set at 1:80 accordingly. The geometric mean ANA titers of the 50 sera from 50 rheumatic disease patients were 676 for HEp-2 cell (CSI), 503 for HEp-2 cell (AFT), 368 for HEp-2 cell (AI), and 265 for MLC, respectively. Although statistically significant difference (p less than 0.05) in geometric mean titer existed between reference method and the other 3 methods, the latter 3 methods still had good sensitivity (97.2% for HEp-2 cell (both AFT and AI); 91.7% for MLC), and specificity (100% for HEp-2 cell (both AFT and AI); 71.4% for MLC) for selecting out sera with abnormal ANA titer. We also evaluated the relationships between ANA titer and anti-double stranded DNA antibody (anti-dsDNA) concentration in another 210 sera from 151 patients with rheumatic disease. Statistically, there is no distinct correlation between anti-dsDNA and ANA of all fluorescence staining patterns except for peripheral pattern, in which case a significant correlation could be demonstrated.

Abstract
In order to evaluate the biological features and clinical significance of myeloid antigen expression in acute lymphoblastic leukemia (ALL), immunophenotype analysis was performed on leukemic cells from 160 patients diagnosed as ALL by the French, American and British (FAB) criteria using a comprehensive panel of monoclonal antibodies to lymphoid and myeloid associated antigens. Expression of myeloid antigens was found in 32 cases (20%), including 11 out of 49 adults (22.4%) and 21 out of 111 children (18.9%). CD33 was positive in 18 patients (11.3% of the total cases), CD13 in 15 patients (9.4%), CD 11b in 12 patients (7.5%) and CD14 in 1 patient (0.6%). Nine patients expressed two or more myeloid antigens. There were no significant differences in clinical manifestations and hematological pictures between the ALL patients with myeloid antigen expression (My+ ALL) and those without (My- ALL). No consistent chromosomal abnormality was found in My+ ALL. Eighty percent of the childhood and 44.4% of the adult My+ ALL patients achieved complete remission, compared with 87% and 80%, respectively, for childhood and adult My- ALL, but the differences were not statistically significant. After a median follow-up of 2.1 years, there were also no statistically significant associations between myeloid antigen expression and shorter duration of remission or poorer survival rate for patients with both adult and childhood ALL.

Abstract
A nine-year-old boy, victim of Cooley anemia, received allogeneic bone marrow transplantation with his younger brother serving as the histocompatible donor. The myeloid and erythroid series recovered very quickly, but his platelet count never reached 10(5)/mm3 until the 220th day. Platelet-associated IgG (PAIgG) was checked on the 137th and 305th day with the level of 31.75 fg/pl and 6.84 fg/pl, respectively. Immune mediated process was considered to be the cause of his prolonged thrombocytopenia.

Abstract
Among 160 patients who were diagnosed as having acute lymphoblastic leukemia (ALL) by French American British (FAB) criteria, 32 patients (20%) expressed myeloid-associated antigens on leukemic blasts (My+ALL). Correlation of immunophenotype with rearrangement of immunoglobulin (Ig) heavy chain and T-cell receptor (TCR) beta chain genes was performed on 73 of these patients (21 were My+ALL). Rearrangements of both Ig and TCR genes (double rearrangements) were detected in 24 patients, including three (19%) of 16 T-lineage ALL. 17 (33%) of 52 B-lineage ALL, and four of five ALL expressing both B and T-cell surface markers. Also a higher incidence of double rearrangements in My+ALL was found as compared with My-ALL (43% vs 29%). This difference was more evident when only B-lineage ALL was considered (50% in My+ patients vs 24% in My- patients). However the difference is not statistically significant yet possibly due to the small number of patients in the study. Further studies on more patients are needed to confirm this. In My-B-lineage ALL, rearrangements of TCR beta chain gene were restricted to certain subgroups (Groups III & IV) of patients who expressed CD10 surface antigens but lacked cytoplasmic Ig. In My+ B-lineage ALL, rearrangements of TCR beta chain gene could be found in various subgroups studied (Groups II through V). Cross-lineage gene rearrangement in My+ALL may involve mechanisms different from those in My-ALL.

Abstract
Among 77 unselected patients with chronic myelogenous leukaemia (CML), 70 had Philadelphia chromosome (Ph1) in blood cells. Extra chromosomal abnormalities were noted in 4%, 55% and 78% of Ph1-positive patients in chronic phase, accelerated phase and acute blast crisis, respectively. Rearrangement of the bcr was detected in 46 of 47 Ph1-positive patients studied and also in three of five Ph1-negative ones. The locations of the breakpoints were mapped to one of four zones of the bcr in 45 patients. The median duration from diagnosis of CML to onset of acute blast crisis was not significantly different between the two groups of patients with breakpoints in the 5' portion (34 months), and in the 3' portion (39 months) of the bcr. In addition, the locations of the breakpoints within the bcr did not change as the disease progressed in the six patients who had DNA analysed both in the chronic phase and subsequently in transformation. In one of them, an additional aberrant band which was not present in the beginning of the acute phase was detected in blood cells taken 2 months later. It is suggested from the studies that transformation of CML may not be related to alterations within the bcr.

Abstract
A retrospective study on the clinical features of acute rheumatic fever (RF) with carditis in 45 patients, 15 years of age and older (range 15-61), is described. Nineteen patients were seen at initial attack; the remaining 26 patients (28 recurrences) were admitted because of RF recurrence. Of the total 47 episodes, carditis was manifested by a significant murmur without previous RF or any known rheumatic heart disease in 40%; change in the character of a murmur under observation or the appearance of a new murmur in 15%; and acute pericarditis in 19%. Congestive heart failure of recent onset was noted in 85% of the episodes, while classical polyarthritis or polyarthralgia occurred in 57%. The aortic valve was newly damaged or preexisting aortic regurgitation worsened in 12 episodes. Twenty-nine patients were followed for 1/2-16 years. Of 11 patients with an initial attack who were maintained on regular prophylaxis (intramuscular benzathine penicillin 1,200,000 units every 4 weeks), the mitral valve murmur disappeared in 3 and none of the patients had recurrence. Of the remaining 18 patients with no or incomplete prophylaxis, 1 died from congestive heart failure 6 months later, and 3 had recurrences with involvement of the aortic valve. In conclusion, RF with carditis in adolescents and adults in our practice at the National Taiwan University Hospital is likely to show more cardiac problems and complications than that seen in the West. Although active rheumatic carditis among this patient population is relatively uncommon, recurrences with subsequent involvement of the aortic valve (aortic regurgitation) do occur.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
An increasing number of acute leukemias coexpressed markers normally believed to be restricted to a single lineage have been found recently. This special subgroup of leukemias have drawn a lot of attention because of their biologic and clinical significance. In a study of 100 consecutive de novo ANLL patients diagnosed by FAB criteria, T-cell antigen CD7 was identified on the leukemic blasts of 13 patients, ten of whom had M1 subtype of leukemia, myeloblastic leukemia without maturation. All the patients showed positive staining with myeloperoxidase and expressed myeloid markers CD13 and/or CD33, but lacked CD11b, a marker of more mature myeloid cells. Combined staining with myeloperoxidase and CD7 of the cells from four patients revealed coexpression of both markers on the same cells. None of the patients expressed the two other T-cell antigens CD2 or CD5. All ten patients who had DNA analysis showed germline configuration of TCR beta and gamma chain genes. One patient had chromosomal translocation involving 11q23, t(11; 19) (q23; p13), which is the site frequently associated with both myeloid and lymphoid malignancies. The clinical implications of this subgroup of patients need further study on more patients, and need longer follow-up.

Abstract
Twenty-eight adult patients with primary refractory or relapsed acute leukemia were treated. The regimens consisted of mitoxantrone plus cytosine arabinoside for 17 patients with acute non-lymphocytic leukemia (ANLL) and mitoxantrone accompanied with vincristine and prednisolone for 11 patients with acute lymphoblastic leukemia (ALL). In primary refractory patients, 1 of the 4 (25%) ANLL and 1 of the 3 (33%) ALL attained complete remission (CR). Excluding 2 patients who underwent bone marrow transplantation, 8 of the 13 (62%) relapsed ANLL and 4 of the 8 (50%) relapsed ALL achieved CR with a median duration of remission of 6.2 months and 3.8 months, respectively. Myelosuppression occurred in all treatment courses and was associated with pyrexia due to infections in 84% of the cases. Nausea, vomiting and stomatitis were mild. Abnormal liver function tests were observed in 8 (28%) patients. One patient, pretreated with 550 mg/m2 of doxorubicin, developed congestive heart failure. The results suggest that mitoxantrone is of value in the treatment of Chinese patients with refractory or relapsed acute leukemia.

Abstract
Lupus anticoagulant (LAC), an autoantibody, in maternal circulation is responsible for a high incidence of fetal loss. We record 2 cases of recurrent fetal loss in association with LAC. The presence of LAC was diagnosed by prolonged activated partial thromboplastin time (aPTT), but was not correctable by dilution with normal plasma. During their subsequent pregnancies, these two women were treated with prednisolone and a low dose of aspirin (100 mg/day). Normal values of aPTT were achieved in both cases after treatment. Preeclampsia developed in one of the women, and a live premature infant was delivered by cesarean section. However, a successful term pregnancy was achieved in the other case. Corticosteroid and low-dose aspirin appear to improve fetal outcome in cases with LAC.

Abstract
Cytogenetic study was performed in the past 3 years on 23 Chinese patients with Philadelphia chromosome (Ph) positive chronic myelogenous leukemia (CML) in transformation; seven were in accelerated phase and 16 in acute blast crisis. Chromosomal abnormalities in addition to Ph were found in three (43%) of the patients at accelerated phase and 14 (88%) of the patients at blast crisis. The common nonrandom chromosomal aberrations were double Ph, trisomy 8, trisomy 19, and trisomy 21, which occurred in 47%, 41%, 35%, and 29%, respectively, of the total patients with extra chromosomal abnormalities. Isochromosome for the long arm of chromosome 17 was found in only one patient. In patients with blast crisis, the type of blast cell was characterized through morphologic, cytochemical, and immunocytochemical studies. Eleven cases were classified as myeloid and five as lymphoid transformation. Trisomy 8, 19, and 21 were detected only in patients with myeloid blast crisis. This study also revealed a high incidence of trisomy 21 and a low incidence of i(17q) in Chinese patients with transformation of CML.

Abstract
The frequency, pattern, extent and clinical features of bone marrow involvement in 94 cases of non-Hodgkin's lymphoma, classified according to the International Working Formulation, were reviewed. In 30% of cases there was bone marrow involvement by lymphoma at the time of diagnosis. Marrow involvement was most frequently found in the follicular small cleaved cell (57%), diffuse mixed small and large cell (56%), and lymphoblastic (56%) lymphomas. A paratrabecular pattern of marrow involvement tended to occur in low or intermediate grade lymphomas. High grade lymphomas tended to show an interstitial or diffuse pattern of marrow involvement. The results of marrow aspiration and biopsy were of equal value and complementary to each other. In 43% of cases with marrow lymphoma there was peripheral blood involvement at the time of diagnosis. Blood involvement was most frequently found in the lymphoblastic lymphoma (70%). In general, the degree of blood involvement was related to the extent of marrow involvement. Patients with marrow involvement often presented with "B" symptoms and hepatomegaly. Abnormalities in at least one of the blood counts were quite common (93%). A normal blood count made marrow involvement unlikely but not impossible. Other common laboratory findings included hyperimmunoglobulinemia (47%) and elevated serum levels of lactate dehydrogenase (56%). Patients with marrow involvement showed a significantly higher frequency of hepatomegaly and abnormal blood counts, as compared to those with negative marrows (p less than 0.05 and less than 0.001, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
To elucidate the clinicopathologic features of non-Hodgkin's lymphoma (NHL) in Taiwan, 123 adult patients with proven NHL were studied. They were classified according to the international working formulation as: low grade (LG), 12.2%; intermediate grade (IG), 42.3%; and high grade (HG) lymphoma, 45.5%. The most common subtypes were diffuse large cell (26.8%) and large cell immunoblastic (26.8%) lymphomas. Follicular lymphoma accounted for only 8.9% (11 cases). Complete remission rates for LG, IG and HG lymphomas were 53%, 35% and 34%, respectively. LG lymphoma had a significantly better survival than that of IG and HG lymphomas. The IG lymphoma encompassed a heterogeneous group of patients with varying prognoses but the overall survival curve was indistinguishable from that of HG lymphoma. Clinically, 66% of HG, 77% of IG and 86% of LG lymphoma presented with advanced disease. LG lymphoma had high frequencies of hepatosplenomegaly (30-50%) and bone marrow involvement (53%), whereas skin, bone and central nervous system involvement occurred exclusively in IG and HG lymphomas. Mild anemia was common and occurred in 40-50% of the patients. Hyperimmunoglobulinemia was found in 50-60% of all 3 grades of lymphoma, monoclonal gammopathy in 3 cases of IG lymphoma, and hypercalcemia in 4 cases of IG and HG lymphomas. Elevated serum lactate dehydrogenase occurred mainly in IG and HG lymphomas and was an important prognostic factor. In conclusion, the characteristic features of NHL in Taiwan include: (1) a high proportion of HG lymphoma and low proportions of LG and follicular lymphomas; (2) a heterogeneous patient composition of IG lymphoma with an unfavorable overall prognosis.(ABSTRACT TRUNCATED AT 250 WORDS)
