Only a minority of all patients with CML can today be treated by allogeneic bone marrow transplantation (BMT) but the probability of cure for such patients is high. The complications of BMT are similar to those that occur following transplant for other diseases, notably GVHD, pneumonitis and infections. Of special interest is the demonstration that a graft-versus-leukaemia effect plays a role in the cure of CML. Studies using the polymerase chain reaction to detect minimal residual disease (BCR/ABL transcripts) may prove useful in predicting relapse and optimizing conditioning schedules. It is now important to test whether BMT can be equally successful in older patients (over 50 years) and in those lacking HLA-identical sibling donors. For other patients autografting may offer the possibility of achieving complete cytogenetic remission and perhaps prolonging life.

A fifty-one-year-old male patient visited the Department of Dermatology of Toho University Ohashi Hospital with a complaint of generalized exanthema, which was diagnosed assyringoma; at that time his leukocytosis was recognized. He was admitted to our department on August 8, 1988. Physical examination on admission revealed slight hepatosplenomegaly. WBC count was elevated (50,700/microliters). He was diagnosed as having Ph1-positive CML in the chronic phase and was treated with IFN-alpha (HLBI, Sumitomo, 3 x 10(6) units/day, daily, I. M.) from August 12, but an elevated lesion was detected at the lower part of his esophagus by endoscopy, and it was diagnosed by biopsy as squamous cell carcinoma. Radical operation for esophageal cancer was performed on September 26; at that time his WBC count was 17,400/microliters. After discharge, his WBC level was maintained within normal range by IFN-alpha. On August 2, 1989, he was readmitted to our hospital because of lymphoblastic crisis. Although he attained transient complete remission, he died of pneumonia after the relapse on January 10, 1990. IFN-alpha therapy is suggested to be useful for the treatment of CML associated with gastrointestinal cancer because of its possible parenteral administration and mild toxicity.

Seven cases of miliary tuberculosis in patients with hematologic disease were analyzed clinicopathologically. Mean age of the patients was 65 years, and the hematologic diseases were CML, AML, ALL, MDS and malignant lymphoma. Diabetes mellitus was present as a complication in three patients. Miliary tuberculosis was found in 5 cases during the first admission to our hospital owing to hematologic problems. In 4 of 6 cases, fever had started more than two months before admission, consequently, the tuberculosis probably began about that time. After admission, chemotherapy was administered in 5 cases, and steroid in 6 cases for hematologic disease. The mean total quantity of steroid administered was 2,134 mg of prednisolone and average treatment duration was 69 days. The chest roentgenographic shadow was so atypical that miliary tuberculosis was suspected in only one case. The initial chest roentgenogram showed hilar and mediastinal lymph node swelling as well as the shadow of pulmonary tuberculosis in two cases. It was thought that the hilar and mediastinal lymph node swelling could be explained by primary complex, although the patients were of advanced age, or by "secondary complex" reported by Terplan, K in 1940. The diagnosis of tuberculosis was made in two patients before their death by smear of aspirated fluid of cervical lymph node and by bone marrow cell block in one patients, and by pathological examination of mediastinal lymph node biopsy in the other patients. Tubercles were found from bone marrow cell block in 2 out of 5 patients and from bone marrow biopsy in 1 out of 3 patients, but the positive results were reported in 2 patients following death. Smears of sputum, gastric juice, urine, spinal fluid and pleural effusion were negative in all cases. One patient diagnosed as miliary tuberculosis also had pneumocystis carinii pneumonia. This case was treated with antituberculosis drugs for 20 days without improvement. Another patient diagnosed as miliary tuberculosis improved under treatment with antituberculosis drugs, but died of cytomegalovirus pneumonia. Autopsy in 5 cases revealed non-reactive miliary tuberculosis, and pulmonary hemorrhage probably due to DIC was present as a complication in two cases. In these cases, severe immunosuppression, which is a major precipitating factor of miliary tuberculosis, is thought to be induced by hematologic disease itself, chemotherapy, steroid or other underlying disease such as diabetes mellitus. Miliary tuberculosis in such compromised host is cryptic and progresses rapidly. Consequently, early diagnosis is very important. Retrospectively, the unexplained pyrexia was most important to suspect tuberculosis.(ABSTRACT TRUNCATED AT 400 WORDS)

Bone marrow transplantation was performed between IV/82 and X/85 in 64 patients with acute leukemia (n = 36), chronic myelogenous leukemia (CML; n = 13), severe aplastic anemia (n = 12), and neuroblastoma stage IV (n = 3). Of these patients 57 received allogeneic marrow from HLA-ABCDR identical, MLC-negative sibling donors. Six transplants were performed with syngenic marrow and one with autologous marrow. Of the 64 patients 48 survived 40-1,250 days after transplantation, resulting in a survival rate (SR) of 75% and a survival probability (SP) of 71%. Of the 36 patients suffering from acute leukemia (SR = 64%, SP = 51%), patients with acute myelogenous leukemia (AML) in first complete remission (n = 11; SR = 81%, SP = 76%), as well as patients with acute lymphatic leukemia (ALL) in 1st to 4th complete remission at the time of transplantation (n = 14; SR = 81%, SP = 76%) show a favorable prognosis. A poor survival rate was seen for patients with AML when transplanted in second or partial remission (1/5; SR = 20%), as well as for patients suffering from ALL and transplanted during relapse or partial remission (1/6; SR = 16%). Of 13 patients suffering from CML 12 survived the transplantation free of relapse (SR = 93%, SP = 92%), and one patient died from varicella zoster pneumonia. Of the transplanted patients with severe aplastic anemia, 12 of 13 are surviving with complete hematologic reconstitution; one patient, however, died on day 10 from a sepsis. In our patient group, the SR as well as the SP has been improved through changes in the irradiation protocol concomitant with prophylactic application of anti-CMV hypergammaglobulin, as well as through additional oral medication of Azyklovir. The 41 patients (BMT No. 7-47) with total body irradiation at one time show an SR of 44% and an SP of 41%. The following 46 patients (BMT No. 48-93) have reached an SR of 83% and an SP of 74% under the regimen of fractionated total body irradiation, plus prophylaxis with anti-CMV hypergammaglobulin and Azyklovir. Within this group, no fatal CMV pneumonia was encountered as opposed to six patients lost from CMV pneumonia in the first group.

A total of 22 patients with leukemia (10 ALL, 11 AML, 1 CML) have undergone allogeneic bone marrow transplantation (BMT) by the Quebec Co-operative Group for Marrow Transplantation from 1980 to 1982. All patients received 900 cGy total body irradiation (TBI), in a single fraction, on the day preceding BMT. The first 11 patients were treated on a cobalt unit at a constant dose rate of 4.7 to 6.3 cGy/min. Six of these patients developed interstitial pneumonitis (IP). The clinical course of three patients, two with idiopathic and one with drug-induced pneumonitis, was mild and recovery was complete in all. The other three patients developed severe infectious IP and two died. The next 11 patients were treated with a sweeping beam technique on a 4 MV linear accelerator delivering a total tumor dose of 900 cGy at an average dose rate of 6.0 to 6.5 cGy/min but an instantaneous dose rate of 21.0 to 23.5 cGy/min. Eight patients developed severe IP. Five of these were idiopathic and four died. Three were infectious and all died. The fatality of interstitial pneumonitis appeared to be greater in the group treated with the sweeping beam technique.

Ceftezole (CTZ) was administered to 20 patients with hematopoietic malignancy complicated with infections. These patients consisted of 7 cases of AML, 2 ALL, 2 AMMoL, 1 APL, 1 blast crisis of CML, 2 HD, and 5 NHL. In 13 cases, sites of infection were determined and causative organisms were identified. In other 7 cases, sites of infection or causative organisms were unknown. In the former 13 cases, pneumonia was demonstrated in 6 patients, tonsillitis in 4 patients, pyelonephritis in 2 patients and sepsis in 1 patient. Klebsiella was separated from 5 patients as the causative organisms, E. coli from 2 patients, E. coli and Pseudomonas aeruginosa from 1 patient, Pseudomonas cepacia from 1 patient, Streptococcus viridans from 2 patients, Proteus from 1 patient and Torulopsis from 1 patient. Gram-negative rods were separated from 10 of the 13 cases (77%) as the causative organisms. CTZ was administered intravenously in dose from 4 g to 16 g per day combined with other antibiotics (AMK, GM, DKB, TOB, SBPC, CBPC, LC, ST). The response rate in 12 cases of acute leukemia and in 7 cases of malignant lymphoma was 58% and 43%, respectively. Infections occurred in 4 patients with less than 100 neutrophil per mm3 did never favorably responded even with CTZ.

Marrow transplant is potentially curative therapy for CML. Allogeneic sibling-donor marrow transplant may be the therapy of choice for younger patients early in the course of disease. Early transplant is an important influence on disease-free survival and relapse after related-donor transplant therapy, although additional patient characteristics influencing outcome can be identified and may have cumulative adverse effects. The 5-year disease-free survival of patients transplanted within one year of diagnosis and without signs of advanced disease is greater than 65%. Significant problems remain, however, including early mortality (primarily from infection, pneumonia, and pneumonitis) and relapse of CML following transplant, including late relapse occurring more than 5 years posttransplant. For patients without a matched, related donor, unrelated-donor marrow transplant may be a treatment option and can result in successful outcome for patients with CML. Relapse following unrelated-donor marrow transplant is rare. However, the use of an unrelated donor is associated with significant toxicity, including early mortality, engraftment failure, and ongoing morbidity and mortality associated with acute and chronic graft-versus-host disease. For patients who lack an available matched-related or -unrelated donor, autologous marrow transplant has been developed as an alternative approach to therapy. Long-term survival following autologous marrow transplant is possible and may even approach the survival for allogeneic related-donor recipients, although cure of disease is not achieved.

L-selectin is a glycoprotein which is one of three members in a family of cell adhesion molecules called selectins. L-selectin is present in distinct forms on both neutrophil granulocytes and lymphocytes, and it appears to play an important role in the early stages of leukocyte-endothelial cell interaction. Activation of leukocytes leads to shedding of the extracellular part of L-selectin which thus forms a soluble adhesion molecule, sL-selectin, which retains functional capacity and can be detected in serum. In the present study we have developed a specific, sensitive sandwich ELISA to measure the serum level of sL-selectin in patients with hematological and infectious disorders. Three patients with acute myeloid leukemia in remission and 1 patient with chronic myeloid leukemia in chronic phase were followed during bone marrow transplantation and the level of sL-selectin was found to correlate closely to the leukocyte counts with no detectable sL-selectin during periods of severe leukopenia. In 11 patients with chronic phase chronic myeloid leukemia and 13 patients with chronic lymphocytic leukemia the sL-selectin level was also found to correlate closely to the leukocyte count (R = 0.98; p = 0.001 and R = 0.83; p = 0.004 respectively). One CML patient with a leukocytosis of 385 x 10(9)/l was found to have an sL-selectin concentration 625 times above normal. Ten patients with acute pneumonia were evaluated at diagnosis and at the time of follow-up 4-8 weeks later. In all patients the initial sL-selectin level was higher than at follow-up. However, no close correlation between sL-selectin and leukocyte count or CRP (C-reactive protein) at the time of diagnosis was found. In summary, we have found that the sL-selectin level in human serum closely correlates to the leukocyte count in both CML and CLL and during bone marrow transplantation.

Seventy-three BMT procedures (42 allogeneic-BMT, 30 autologous-BMT, 1 syngeneic transplant) were undertaken at the Shariati Hospital in Tehran between March 1991 and November 1993. Allogeneic-BMT was performed for thalassaemia major (n = 23), AML in complete remission (n = 3), severe aplastic anaemia (n = 7), CML (n = 7), dyskeratosis congenita (n = 2) and Fanconi anaemia (n = 1). Conditioning regimens comprised busulphan (BU) plus cyclophosphamide (CY) or CY only. Thirty-two (78%) of the 43 patients remain alive 1-34 months after BMT. Twelve patients died: the causes of death were haemorrhagic cystitis (n = 1), CMV pneumonitis (n = 1), GVHD (n = 3), infection (n = 3), rejection (n = 1), VOD (n = 2) and hepatitis (n = 1). Autologous-BMT was performed for patients with AML in CR (n = 16), ALL in CR (n = 9), lymphoma in relapse (n = 3), Ewing sarcoma (n = 1) and multiple myeloma (n = 1). The median age was 18 years. Conditioning regimens were Ara C plus CY, etoposide plus CY and high-dose melphalan. Sixteen (54%) of the 30 patients survive, 14 in continuous complete remission. The causes of death were relapse (AML (n = 7), ALL (n = 4), lymphoma (n = 1)), VOD (n = 1) and infection (n = 1).

Recently, the incidence of opportunistic infections in patients with hematological neoplasms has been markedly increasing. However, early and definitive diagnosis and treatment of these infections remain difficult. In this study, we report three patients, a 47-year-old female with ATL, a 54-year-old female with CML and a 65-year-old female with ATL. All these cases were complicated with pneumonia caused by Pneumocystis carinii (Pc) or cytomegalovirus (CMV). They were successfully treated with sulfamethoxazole/trimethoprim or ganciclovir after detection of the respective microorganisms from sputum samples in the early stage of the infections by polymerase chain reaction (PCR) method. The above clinical evidence demonstrated the PCR technique to be a rapid and sensitive diagnostic procedure for the detection of Pc or CMV and to be helpful for the early initiation of appropriate treatment of the infections in patients with hematological neoplasms.
