A clinical trial of the oral form of VP 16-213 (NSC-141540), a semisynthetic podophyllotoxin, was undertaken. In 20 patients, treatment was started at 200 mg/day p.o. for 5 days; courses were repeated after a rest period of 16 days. Five patients were treated at the same dose, repeated with only 9-day rest periods. Subsequently, 65 patients were given 300-400 mg/day for 5 days, with rest periods of 9 days between courses. The side effects encountered included anorexia, nausea and vomiting, stomatitis, diarrhea, leukopenia, thrombocytopenia, alopecia, and pruritus. Substernal discomfort with or without palpitations was reported by 18 patients; no explanation for this symptom could be found. No complete remissions (CR) were observed. Parital remissions (PR) and improvement (IMP) were seen as follows: small cell carcinoma, lung (10 patients)--2 PR, 3 IMP; adenocarcinoma, lung (4 patients)--1 PR; alveolar cell carcinoma, lung (1 patient)--1 IMP; mesothelioma (4 patients)--1 IMP; ovarian cancer (12 patients)--3 PR, 3 IMP; breast cancer (20 patients)--4 IMP; colon cancer (8 patients)--2 IMP; bladder cancer (4 patients)--2 IMP; histiocytic lymphoma (7 patients)--2 PR, 3 IMP; chronic myeloid leukemia (1 patient)--1 IMP.

Splenectomy was performed in 45 patients with chronic myelogenous leukemia; 23 were in the chronic phase and 22 in the acute phase. Indications for operation included inability to control the disease by chemotherapy or radiation therapy, severe thrombocytopenia, frequent need for blood transfusion and extensive splenomegaly causing discomfort. Median survival time for these patients was better than survival time of other reported groups of patients who did not have a splenectomy. According to our criteria, splenectomy was beneficial to 15 patients in the chronic phase as well as to eight in the acute phase of chronic myelogenous leukemia. Median survival time after splenectomy was higher in patients who had splenectomy within two years of the diagnosis as compared with those who had the operation after two years. Splenectomy did not prevent the future onset of fatal blastic crisis. Although significant abnormalities in coagulation studies were seen in 37 of the patients, intraoperative hemorrhage was not a major problem. Considering the poor general condition, inadequate healing and susceptibility to infection, the postoperative mortality and complication rates were comparable with those reported in series in which splenectomy was performed for other diseases. It seems that splenectomy benefits a selected group of patients with chronic myelogenous leukemia; however, a randomized series would furnish better data upon which to make decisions.

One thousand and five bone marrow biopsies were performed in patients with haematologic or oncologic disorders during a ten year period from 1976 to 1985 according to the method of Jamshidi and Swaim. Indications and method of biopsy are discussed in detail. Major side effects were not observed, however minor accidents (0.2%) as well as problems in yielding biopsy-material (1.6%) are reported. The rate of biopsy-failure, including biopsies with insufficient (crushed) material, was 5%. In our hands the predominant value of the Jamshidi-biopsy for diagnosis of hematologic disorders is given by the following reasons: Bone marrow histology gives a more detailed architectural picture than cytologic smears. Sampling of bone marrow for both methods (cytology and histology) through the same instrument is possible. The procedure is easily performed and gives the patient no more discomfort than a simple sternal puncture. Chronic myeloproliferative disorders (CMPD, 31%), malignant lymphomas (40%) and aplastic (hypoplastic) syndromes (4%) were the most frequent indications for bone marrow biopsy. Clinical and histological findings were compared in 235 patients with CMPD. The histological defined entity of chronic megacaryocytic-granulocytic myelosis could be differentiated easily from chronic granulocytic leukemia (CGL), however it was not always distinguishable from primary thrombocythemia by means of clinical and hematological criteria. Myelofibroses on the basis of CGL were separated from idiopathic or postpolycythemic fibroses by hematological findings. The diagnostic value of bone marrow biopsies was superior to cytology in all CMPD and proved to be an essential diagnostic method in cases with high platelet count. Marrow involvement was found in 59% of 218 previously untreated patients with non Hodgkin's lymphomas and in 9% of 123 patients with Hodgkin's disease. Jamshidi-biopsy proved to be a simple and indispensable procedure in staging of Hodgkin's and non-Hodgkin's lymphomas.

An adolescent girl with chronic myelogenous leukemia was treated with hypnosis for several disease- and treatment-related problems during the last 4 months of her life. Data were collected before and after hypnosis on the nature and intensity of the patient's acute pain and anxiety during bone marrow aspirations, chronic headache and backache, nausea and vomiting during chemotherapy, anorexia, and the discomfort associated with spiking temperatures. Comparisons of baseline and posthypnosis reports suggest that hypnosis was successfully used for acute and chronic pain, anxiety, unpleasant body sensations and, possibly, nausea and vomiting. The hypnotic techniques used, the limitations of hypnosis and clinical issues in this case are presented and discussed.

Transplantation of allogeneic peripheral blood progenitor cells (PBPCs) may have advantages over bone marrow transplantation (BMT) with regards to the speed of hematopoietic and immunologic recovery, which may then shorten the time spent in hospital and decrease costs. The recipient might also profit by an enhanced graft-versus-leukemia reaction exerted by the high number of natural killer cells contained in such grafts. The donor could be spared the discomfort and risks of general anesthesia and marrow harvesting. Primary transplantation of unmanipulated allogeneic PBPCs has not been reported so far because the vast amount of T cells contained in the collection product was thought to cause severe graft-versus-host disease. We present preliminary data on primary transplantation of allogeneic PBPCs in patients who either suffered from advanced leukemia or had a donor unable to undergo general anesthesia. Eight patients with a median age of 42 years suffering from acute myelogenous leukemia (AML) in first remission (n = 3), AML in third remission, AML in relapse (n = 2), acute lymphoblastic leukemia in second remission, or chronic myelogenous leukemia in accelerated phase received myeloablative therapy followed by transplantation of unmanipulated allogeneic PBPCs mobilized with granulocyte colony-stimulating factor (5 to 10 micrograms/kg of body weight of filgrastim administered for 5 to 6 days) in their HLA-identical donors. Hematopoietic reconstitution was achieved in all patients with a median of 15.5 (16.5) days after transplant needed to surpass an absolute neutrophil count of 0.5 (1.0) x 10(9)/L. The median time to an unsupported platelet count greater than 20 (> 50) x 10(9)/L was 19.5 (41) days after grafting. Three patients did not exhibit signs of acute graft-versus-host disease (GVHD), grade I disease was seen in one patient, and three patients experienced grade II disease limited to the skin. The only patient with severe acute GVHD (grade III) refused to take his oral cyclosporin regularly and had ineffective serum levels for most of the time until relapse. Six of eight patients are currently alive without evidence of disease between 61 and 533 days after grafting; two patients grafted for AML in relapse achieved a complete remission after transplantation but relapsed again and died of leukemia on days +48 and +70, respectively. Primary transplantation of unmanipulated allogeneic PBPCs is feasible and results in long-term engraftment without causing detrimental GVHD.

A 66-year-old woman complained of chest discomfort in January 1995. In March the accelerated phase of chronic myeloid leukemia (CML) was diagnosed. Chromosomal analysis demonstrated negative Ph and positive t(9;16) (q34;p11) with positive major BCR/ABL chimeric mRNA. Administration of hydroxycarbamide was initiated, but in May she developed high fever and severe left hypochondralgia. Her WBC was 62,100/microliter (blast 64%), and LDH was 3,590 IU/l. Bone marrow examination showed 78.6% blasts, with a nucleated cell count of 74 x 10(3)/microliter. Blasts were negative for esterase stain and partially positive for both peroxidase stain and PAS reaction. Surface marker analysis revealed that blasts were positive for CD13, CD19, CD33, CD34, and HLA-DR. A diagnosis of blast crisis was made and she was treated with the VDS-CP regimen with heparin for DIC. After temporary improvement her disease recurred rapidly with severe DIC. Treatment with low molecular weight heparin and fresh frozen plasma failed to control DIC and she died of subarachnoid hemorrhage on the 48th hospital day. This is the first veprted of case Ph-negative, M-BCR/ABL-positive CML with t(9;16) accompanied by severe DIC.

Myelofibrosis with myeloid metaplasia (MMM) is a collective term that describes the related disorders AMM, PPMM, and PTMM. The chronic myeloid disorders include chronic myeloid leukemia, polycythemia vera, essential thrombocythemia, and agnogenic myeloid metaplasia (myelofibrosis). These disorders display varying propensities for pathologic enlargement of the spleen which can lead to mechanical discomfort, hypercatabolic symptoms, anemia, thrombocytopenia, and portal hypertension. Splenectomy has been found to be of little benefit in the early stages of chronic myeloid leukemia. Similarly, the benefit of splenectomy in advanced cases is limited to symptomatic palliation and treatment of delayed engraftment after allogeneic bone marrow transplantation. Although polycythemia vera and essential thrombocythemia are also characterized by splenomegaly, splenectomy is not considered a therapeutic option in the absence of transformation of the disease into myelofibrosis with myeloid metaplasia. Splenectomy has been studied most in myelofibrosis with myeloid metaplasia. Although there is no clear survival advantage to splenectomy in this disorder, the surgical procedure can result in substantial palliation of mechanical discomfort, hypercatabolic symptoms, portal hypertension, and anemia. However, the procedure is associated with an approximately 9% mortality rate, and the postsplenectomy occurrence of extreme thrombocytosis, hepatomegaly, and leukemic transformation is of major concern.

Real-time quantitative polymerase chain reaction (PCR) for BCR-ABL mRNA in the peripheral blood (RQ-PCR) provides an accurate and reliable measure of response to therapy in chronic myeloid leukaemia (CML). We wanted to determine in what circumstances additional clinically relevant information was provided by simultaneous cytogenetic analysis in RQ-PCR monitored patients receiving imatinib treatment. We analysed 828 simultaneous RQ-PCR and bone marrow cytogenetic analyses from 183 patients with chronic phase CML with a median follow-up of 20 months. Cytogenetic progression was defined as Philadelphia (Ph)-positive clonal evolution, loss of complete cytogenetic response or an increase of > or = 20% Ph-positive cells. Cytogenetic progression occurred in 24/183 (13%) patients. At the time of cytogenetic progression, none of the 24 patients had a major molecular response (MMR; > or = 3-log reduction in BCR-ABL from standardised baseline). There were 320 RQ-PCR results from 95 patients indicating MMR. No abnormality was detected in any of the corresponding cytogenetic analyses. A policy of regular RQ-PCR monitoring with cytogenetic analysis targetted only to patients who have not achieved, or have lost MMR would represent a rational approach to monitoring and spare most patients the discomfort of multiple marrow aspirates. This approach depends upon availability of an accurate, reproducible RQ-PCR assay with ongoing quality assurance.

A methanesulfonic acid ester of the aminoglycols, 3,3'-iminodi-1-propanol, dimethanesulfonate (ester), p-toluenesulfonate (NSC-140117) has been found to be very effective in inducing and maintaining complete remissions in early cases of chronic myelogenous leukemia. The drug was given in daily doses of 1-2 mg/kg for remission induction and 0.5-1.0 mg/kg for remission maintenance, with dose adjustment according to blood cell counts. It induced complete remissions (normal white blood cell count and complete disappearance of splenomegaly) in all nine patients treated and has been maintaining these remissions (as well as a complete remission which was originally induced by NSC-84641 in an additional patient) for a period of 2 1/3 + to 15 1/3 + months. The only toxic effect observed occurred in two patients who had mild discomfort in the upper abdomen associated with soft stools. We need further observations, however, regarding the chronic toxic effects of this drug. The myelosuppressive effect of NSC-140117, within the dose range used, is granulocyte specific and appears less long lasting than that of busulfan.

Therapeutic approach for chronic myeloid leukemia (CML) patients has undergone a revolutionary change with the introduction of tyrosine kinase inhibitors, which improved overall survival and quality of life. Optimal therapy adherence has become of paramount importance to maximize the benefits in the long-term outcome. Several evidences have been reported that personal factors, such as social support, psychological and subjective perceptions about the drug used and the future, could influence adherence. We here report the results of a questionnaire specifically designed to evaluate factors influencing adherence and perceptions about the future, distributed to patients during regional Italian meetings. Overall, 1133 patients compiled the questionnaire: median age was 57 years. High rate of adherence was reported, but 42% of interviewed patients admitted that they had occasionally postponed a dose and 58% had discontinued therapy mainly for forgetfulness. The majority of patients discussed with personal physician about the importance of adherence and received sufficient information about illness and treatment, but would like to have discussed more about discomfort, anxiety and fear of the future. Summarizing personal drug compliance and estimating how many days a month, on average, the patients did not take the drug, the majority answered that it was less than 3 days (55%) and only a minority (4%) admitted that it was more than 7 days. Interviewed about discontinuation, 49% of patients answered that wouldn't interrupt because of fear of losing all the results achieved so far. This study suggests a higher level of satisfaction with more information received but the need of improving communication about possible future treatment free remission.
