Creation of an artificial subcutaneous arteriovenous fistula was attempted in five patients with malignant haematological disorders (two with Hodgkin's disease, two with acute lymphatic leukaemia, and one with acute myeloid leukaemia). The average time from the start of treatment to attempted creation of the fistulae was four years. Neither direct arteriovenous anastomosis nor an interposition mandril graft was successful in any patient. Failure was attributed to impaired venous run-off secondary to previous episodes of thrombophlebitis induced by the intravenous administration of cytotoxic drugs. The use of an arteriovenous fistula early in the course of the disease might minimize these later problems.

Last year, we reported that human papilloma virus type 16 genome (HPV 16 genome) was detected in a case (S.Y.) of bladder carcinoma in situ (bladder CIS) (Cancer Res., 1988). Since then, a number of bladder tumors other than CIS were searched for HPV genome. However, no HPV genome was detected in the bladder tumors. From the results, we consider that HPV may not have a relation with all types of bladder tumor but with only a part of it. In the current report, the case (S.Y.) is presented more precisely than before, in particular on the characteristic bladder lesion. The patient was a 40-year-old female with immunodeficiency and anemia who was referred from a hospital with a complaint of asymptomatic pyuria. Cystoscopic examination revealed a bladder tumor, well-demarcated, white and velvety lesion with slight elevation. On November 25, 1987, she underwent total cystectomy, resection of the anterior vaginal wall and of a part of vulval skin, and ileal conduit formation. Postoperative course was stormy because of bleeding from the wounds and thrombophlebitis in the right femoral vein. In spite of the episodes, she eventually recovered and was discharged 2 months later. However she was readmitted 9 months later due to severe anemia which was ascribed to acute myelogenous leukemia. She is now on cancer chemotherapy for leukemia.

The administration of cytosine arabinoside (araC) by continuous IV infusion requires the patient to be in hospital and have prolonged IV cannulation. In this study the pharmacokinetics of araC during continuous IV infusion were compared with those of continuous SC infusion in six patients with acute myelogenous leukaemia. Each patient acted as his own control. The mean plasma levels of araC reached a plateau within 2 h and the plasma concentrations and the area under the curve were similar for both methods of administration. The mean area under the curve (AUC) was 1147 +/- 230 ng/ml for the IV infusion and 1017 +/- 238 ng/ml for the SC infusion. The plasma araC concentrations showed wide interpatient variation, and there was also considerable variability in the plasma concentrations of araC within the individual patients after a plateau had apparently been reached. Subcutaneous infusion was well tolerated by the patients without any local discomfort or excoriation and SC infusion of araC is thus a feasible alternative to IV infusion. It allows the patients the benefits of being at home, while avoiding unnecessary thrombophlebitis.

Bryostatin 1 is a novel antitumour agent derived from Bugula neritina of the marine phylum Ectoprocta. Nineteen patients with advanced solid tumours were entered into a phase I study to evaluate the toxicity and biological effects of bryostatin 1. Bryostatin 1 was given as a one hour intravenous infusion at the beginning of each 2 week treatment cycle. A maximum of three treatment cycles were given. Doses were escalated in steps from 5 to 65 micrograms m-2 in successive patient groups. The maximum tolerated dose was 50 micrograms m-2. Myalgia was the dose limiting toxicity and was of WHO grade 3 in all three patients treated at 65 micrograms m-2. Flu-like symptoms were common but were of maximum WHO grade 2. Hypotension, of maximum WHO grade 1, occurred in six patients treated at doses up to and including 20 micrograms m-2 and may not have been attributable to treatment with bryostatin 1. Cellulitis and thrombophlebitis occurred at the bryostatin 1 infusion site of patients treated at all dose levels up to 50 micrograms m-2, attributable to the 60% ethanol diluent in the bryostatin 1 infusion. Subsequent patients treated at 50 and 65 micrograms m-2 received treatment with an intravenous normal saline flush and they did not develop these complications. Significant decreases of the platelet count and total leucocyte, neutrophil and lymphocyte counts were seen in the first 24 h after treatment at the dose of 65 micrograms m-2. Immediate decreases in haemoglobin of up to 1.9g dl-1 were also noted in patients treated with 65 micrograms m-2, in the absence of clinical evidence of bleeding or haemodynamic compromise. No effect was observed on the incidence of haemopoietic progenitor cells in the marrow. Some patients' neutrophils demonstrated enhanced superoxide radical formation in response to in vitro stimulation with opsonised zymosan (a bacterial polysaccharide) but in the absence of this additional stimulus, no bryostatin 1 effect was observed. Lymphocyte natural killing activity was decreased 2 h after treatment with bryostatin 1, but the effect was not consistently seen 24 h or 7 days later. With the dose schedule examined no antitumour effects were observed. We recommend that bryostatin 1 is used at a dose of 35 to 50 micrograms m-2 two weekly in phase II studies in patients with malignancies including lymphoma, leukaemia, melanoma or hypernephroma, for which pre-clinical investigations suggest antitumour activity.

The association between venous thrombosis and cancer has been known for a long time. Thrombophlebitis often occurs during the course of a known cancer, but sometimes constitutes the presenting sign. Based on a series of 10 cases of deep venous thrombosis (DVT) revealing an underlying cancer, the authors analyse the various aspects of this association and the elements which help to guide the diagnosis towards a cancer. A simple assessment comprising clinical examination, full blood count and differential white cell count, erythrocyte sedimentation rate, protein electrophoresis, chest x-ray and abdomino-pelvic ultrasonography was performed on admission in 75 cases of presumably idiopathic DVT and revealed a cancer in 10 cases: 6 women and 4 men with a mean age of 53 years. Cancers were located in the urogenital tract in 5 cases, in the bronchi in 2 cases, in the stomach in one case, and there was one case of acute myeloblastic leukaemia (AML) and another case of liposarcoma of the left iliac fossa. The histological type most frequently encountered was adenocarcinoma in 6 cases. In 9 out of 10 cases, the cancer was discovered at the stage of metastases. However, a localized cancer was detected in one case, in which surgical treatment allowed cure of the patient. Comparison of the various characteristics of DVT between the group of DVT revealing a cancer and the group of DVT which remained idiopathic did not reveal any statistically significant difference. A simple, inexpensive assessment looking for a cancer must be systematically performed in all cases of idiopathic DVT in patients between the ages of 50 and 85 years. Other more elaborate examinations may be requested on the basis of the results of the preliminary assessment.

A 66-year-old woman suffering from fever and thrombophlebitis was referred to our hospital. A peripheral blood examination revealed hyperleukocytosis with 96% blast cells and thrombocytopenia. The patient was diagnosed as having acute myeloid leukemia (AML) accompanied by disseminated intravascular coagulation (DIC). A marked decrease in protein C (PC) antigen and activity were observed. In this case, PC levels were lower than those observed in AML with DIC. Induction therapy for leukemia and treatment of DIC were started on the first day of hospitalization. The patient achieved complete remission, with PC antigen and activity levels normalized.

Advances in medicine are allowing patients with hematologic disease to live longer and healthier lives than ever before. As these patients age, however, manifestations of their disease processes may develop as complications in other organ systems. We discussed the major genitourinary complications of sickle cell anemia, leukemia, and thromboembolic disease. These range from the benign inability to concentrate urine that is seen in sickle cell disease to renal infarction that results from nephrotic syndrome. Our ability to treat and prevent these complications will improve as our understanding of these disease processes and their pathophysiology grows. Additionally, it is important for urologists to understand the underlying pathophysiology of hematologic disease to best serve the patients. For example, it may be the urologist who makes the diagnosis of ovarian vein thrombosis in a pregnant woman with right lower quadrant pain and fever. This diagnosis, with the proper treatment of antibiotics and anticoagulation, could prevent the potential development of septic thrombophlebitis. Urologists will increasingly be called upon to deal with the manifestations of these complex diseases as these patients are living longer. It is our duty to educate ourselves about these disease processes so that we can make the best clinical decisions for our patients.

For cellulitis that does not respond to conventional antimicrobial treatment, clinicians should consider, among other explanations, several noninfectious disorders that might masquerade as infectious cellulitis. Diseases that commonly masquerade as this condition include thrombophlebitis, contact dermatitis, insect stings, drug reactions, eosinophilic cellulitis (the Wells syndrome), gouty arthritis, carcinoma erysipelatoides, familial Mediterranean fever, and foreign-body reactions. Diseases that uncommonly masquerade as infectious cellulitis include urticaria, lymphedema, lupus erythematosus, sarcoidosis, lymphoma, leukemia, Paget disease, and panniculitis. Clinicians should do an initial diagnostic work-up directed by the findings from a detailed history and complete physical examination. In many cases, skin biopsy is the only tool that helps identify the correct diagnosis. Special tests may also be needed.

We describe the case of a 38-year-old male patient who had acute myeloid leukemia and developed prolonged neutropenia after induction chemotherapy. He developed thrombotic complications at multiple sites. Thrombophlebitis of the hemorrhoidal plexus became exacerbated and developed into critical cellulitis. Because the patient had no human leukocyte antigen-identical sibling, we considered an alternative donor. Because of the necessity for early neutrophil recovery to resolve the critical infection, we proceeded with allogeneic peripheral blood stem cell transplantation (PBSCT) from a microchimeric haploidentical sibling donor. We infused peripheral blood mononuclear cells directly into the patient without cryopreservation and thawing procedures. We aimed for the contaminating granulocytes to act as a granulocyte transfusion. Actually, the neutrophils increased to 1.6 x 10(9)/L on day 1, when the patient showed a temporary resolution of infection. Engraftment was achieved shortly after neutropenic nadir, and acute graft-versus-host disease (GVHD) has been well controlled. Although the patient experiences extensive chronic GVHD, he has been well as an outpatient with a 90% Karnofsky performance status score. The leukemia has been in complete remission for more than 1 year. These findings suggest the clinical utility of a salvage therapy with allogeneic PBSCT from a microchimeric haploidentical donor to treat refractory leukemia concurrent with life-threatening infection.
