Thirty-four women with metastatic breast cancer were treated at the National Cancer Institute of the National Institutes of Health, with a regimen of leucovorin (L), 500 mg/m2 i.v. over 30 min, followed in 1 h by 5-fluorouracil (5-FU), 375 mg/m2 i.v. bolus on days 1-5, and carboplatin (CBDCA), 50-100 mg/m2 i.v. bolus on days 2-4, every 28 days. All patients had received previous combination chemotherapy with at least one regimen (29 patients with 5-FU-containing regimens). CBDCA, 100 mg/m2 on days 2-4, resulted in grade 4 neutropenia in 10 out of 11 patients associated with sepsis in all 10 patients. CBDCA, 75 mg/m2 (seven patients) and 50 mg/m2 (15 patients), resulted in grade 4 neutropenia in six and eight patients, and neutropenic sepsis in five and two cases, respectively. Grade 4 thrombocytopenia occurred in 10, five and two patients receiving 100, 75 and 50 mg/m2 of CBDCA, respectively. Other toxicities included grade 3/4 mucositis in 18 patients and grade 3/4 diarrhea in 10 patients. Twenty nine patients were evaluable for response, with one pathologic complete response (3%), two partial responses (6%), 18 stable disease (53%) and eight (24%) progressive disease. Sites of response included bone, viscera and soft tissue. The median time from entry on study to progression, for responders, was 15 months. When platinum-DNA adduct formation in peripheral white blood cells was analyzed in 27 patients at 24 h after drug administration, a significant correlation between adduct level and CBDCA cumulative dose was found.(ABSTRACT TRUNCATED AT 250 WORDS)

A series of 23 confirmed cases of pyonephrosis initially treated by percutaneous nephrostomy drainage were reviewed. Presentation was extremely variable, ranging from sepsis to asymptomatic bacteriuria. Fever, flank pain and leukocytosis were often absent. Ultrasonography was diagnostic in only 3 of 12 patients. In all, 17 patients had associated nephrolithiasis, and 5 patients ultimately required nephrectomy. Renal urine cultures were positive in 16 of 21 instances, with multiple organisms found in 8 of 21, and added bacteriological data not provided by bladder urine cultures in 11 cases. A pre-existing history of urinary tract infection, hypertension and malignancy was common. Percutaneous drainage was a safe, quick and effective diagnostic and therapeutic method.

During a 14-year period 23 patients underwent 25 revascularizations for radiation-induced arterial obstructive disease. An average of 5000 rads was delivered, 3 to 24 (mean 9) years before arterial insufficiency, for malignancies of the following origin: gynecologic (n = 9), lymphoma (n = 7), head and neck (n = 5), testicular (n = 1), and lower extremity sarcoma (n = 1). Arterial occlusive disease occurred in the aortic arch vessels (n = 8), visceral aortic vessels (n = 1), and aortofemoral vessels (n = 16). Presenting symptoms were claudication (n = 8), rest pain or nonhealing ulcers (n = 7), transient ischemic attacks (n = 6), asymptomatic bruit (n = 1), and renal insufficiency (n = 1). Reconstructive operations included anatomic bypass (n = 10), extra-anatomic bypass (n = 4), patch angioplasty (n = 5), endarterectomy (n = 3), and resection with interposition graft (n = 1). In this group of patients there were no major perioperative wound complications or other major radiation-associated morbidity. Five patients had late graft infections that manifested from 2 to 5 years after surgery. All occurred in anatomic regions where the bypass graft passed through previously irradiated tissues. Presenting symptoms of infection included a draining groin sinus (n = 3) or soft tissue abscess (n = 2). In all cases the graft had not incorporated into the surrounding tissues when passing through the irradiated area. Treatment included graft excision and extra-anatomic bypass through nonirradiated tissue. One patient died of systemic sepsis. Vascular reconstructive surgery can safely be performed for radiation-induced arterial disease.(ABSTRACT TRUNCATED AT 250 WORDS)

Ninety-three episodes of fever or infection while neutropenic (defined as neutrophil count < 2.0 x 10(9)/l) occurred in 76 patients treated for solid tumours, lymphoma and myeloma over a 4-year period. Most followed the first (39%) or second (18%) cycle of chemotherapy. The neutrophil count at onset of sepsis was < 0.5 x 10(9)/l in 69%. Pathogens were isolated in 32 episodes (34%) and a clinical focus detected in a further 19 (20%). Gram negative bacteria accounted for 51% of pathogens; 49% of bacteria were isolated from blood, 65% of them were Gram negative. The initial antibiotic regimen was cefuroxime with gentamicin or tobramycin in 76 episodes. Fever or infection resolved on first line antibiotics in 78%. The mean duration of antibiotic therapy was 7.6 days. Antibiotic therapy was changed following urine culture in 1.5% of 66 episodes and following chest radiography in 5.8% of 69 episodes, where these tests were performed. Nine (9.6%) patients died from infection, all of whom were receiving second line salvage chemotherapy. Three other patients died of progressive malignancy with sepsis present. In six major diagnostic groups, 56 episodes of infection or fever complicated 4% of chemotherapy cycles.

We investigated the imbalance between thrombin and plasmin activity in vivo with various grades of severity of disseminated intravascular coagulation (DIC) in relation to the underlying diseases. Plasma thrombin-antithrombin-III complex (TAT) and plasmin-alpha 2-antiplasmin complex (PAP) levels were measured in 133 blood samples obtained from patients with DIC. The TAT/PAP ratio was higher in patients with sepsis or solid cancer than in those with hematologic malignancies. In acute promyelocytic leukemia (APL), the TAT levels were the highest, but the PAP levels were even higher and the TAT/PAP ratio was the lowest. As for the severity of DIC, in mild DIC, both thrombin and plasmin activities were increased. In moderate DIC, the TAT/PAP ratio increased, and thrombin activity was much more predominant. However, in severe DIC, the ratio decreased, and plasmin activity became excessive. In 3 patients with acute myeloblastic leukemia, APL and pancreatic cancer, respectively, the PAP level remained high during heparin therapy although the TAT level was decreased. When tranexamic acid was given, the PAP level was selectively reduced, and the TAT/PAP ratio was markedly decreased along with clinical improvement. These results indicate that monitoring of the TAT/PAP ratio may contribute to decisions regarding the institution and performance of combination therapy for DIC using anticoagulants and antifibrinolytic agents.

The need for blood components for oncology patients is small compared with the need for patients with hematologic malignancies. Appropriate use of blood components is necessary, not only medically, but also because of limited supply and availability. Agreement on when to use components is extremely important. In fact, at the time of this writing, the Transfusion Practices Committee of the AABB is conducting an extensive survey on the use of platelets in the oncology and hematology cancer patients (Questionnaire on Institutional Policy on Platelet Transfusion Practice for Hematology/Oncology Patients). The results will, it is hoped, provide a consensus on the proper times and counts that require prophylactic use of components for these patients. Since these patients use the vast majority of components (see Table 15), their proper use is imperative to maintaining an adequate platelet and frozen plasma supply. Transfusion support in cancer patients is vital for their survival. Platelets, in particular, are necessary to prevent serious bleeding. However, refractoriness to platelet transfusions can develop. It must be appreciated that refractoriness is not a general problem and need not require the expensiveness of a universal decision for handling all platelet transfusions in the same manner. Total refractoriness probably occurs in 15 to 20% of patients frequently transfused. In patients in whom frequent platelet transfusion is anticipated, that is, bone marrow transplantation, the development of platelet refractoriness may be reduced by using SDPC and administering them through leukocyte filters. Patients who become refractory to either random or SDPC can either be cross-matched for single-donor platelets that are compatible or can be given HLA-A,B matched platelets. Certainly, the success of platelet transfusion in leukemic patients cannot be denied, since only a small number of these patients now die because of bleeding due to platelet refractoriness. Most of the serious bleeding still seen is associated with sepsis. The risks from transfusion must always be considered. Fortunately, with increased monitoring of the blood supply, they have been reduced. As with any therapeutic regimen, these risks must be weighed against the benefit the patient may gain. Transfusion should always be used prudently.

The authors report their experience with transhiatal esophageal resection accumulated during the period between January 1978 and March 1990. Indications for the procedure included cancer of the gastric cardia (26.3%), cancer of the hypopharynx (3.8%), cancer of the esophagus (59.2%), and benign esophageal disease (9.8%). Esophageal substitution was performed using a tubulized stomach (63.6%), ileo-ceco-coloplasty (28.5%), left colon (7.6%), and jejunum (0.3%). The majority of patients with neoplastic disease were found to be in an advanced stage (67.3% of esophageal cancer patients and 69.7% of cancer of the cardia patients with stage III disease). The mean intra-operative volume of blood transfused varied between 533 and 1,220 ml. Sixteen patients required hospitalization in the intensive care unit. The mean length of post-operative hospitalization varied between 16.8 and 20.6 days. Operative complications included hemorrhage (0.3%) and tracheal injury (0.6%). Operative (30 day) mortality was 5.8%. Causes of death included respiratory insufficiency (35.2%), pulmonary sepsis (23.5%), abdominal sepsis (17.8%), and others (undefined, 23.5%). The 5 year survival was 48.5% for cancer of the gastric cardia, 57.1% for cancer of the hypopharynx and 11.8% for esophageal cancer.

The purpose of this study was to evaluate the impact of repeated intravenous infusions of endotoxin (EN) in patients with cancer on the systemic release of extracellular proinflammatory phospholipase A2 (PLA2) and its relationship to the release of tumor necrosis factor (TNF) and interleukin-6 (IL-6). Six patients received 15 infusion of EN isolated from Salmonella abortus equi at a dose of 4 ng/kg. Marked increase in the activity of circulating PLA2 was noted within 3 h after the first EN infusion and reached a maximal level of 20.4-fold greater than baseline 24 h after infusion. In five patients challenged with EN 2 weeks later, PLA2 reached peak levels 15.5-fold greater than baseline. In two patients who received three sequential daily infusions, the incremental increase in PLA2 activity after the second and third challenge reached maximum levels 6 h after EN infusion. PLA2 response followed those of TNF and IL-6 but was quantitatively different. Whereas maximal levels of TNF and IL-6 declined substantially after repeat EN challenges, no such decline occurred in PLA2 activity. Since, in the clinical setting of gram-negative sepsis, there is recurrent increase in circulating EN, our study approximates this clinical situation and shows that extracellular release of PLA2 follows temporally that of proximal cytokines such as TNF and IL-6. These cytokines may be related to PLA2 release and sustained high activity in the systemic circulation.(ABSTRACT TRUNCATED AT 250 WORDS)

We describe an adult patient who developed persistent hypercalcemia while bedridden for more than three months with pancreatitis and sepsis. On the basis of hypercalciuria, suppressed serum intact PTH, suppressed serum 1,25-dihydroxy vitamin D3 and no clinical evidence of malignancy, the diagnosis of immobilization hypercalcemia was established His hypercalcemia improved during treatment with saline, calcitonin and/or etidronate. With active mobilization and weight-bearing exercises, serum calcium finally normalized. We discuss clinical and laboratory features as well as current modalities of treatment of this rare form of hypercalcemia in adults.

Using primed constant infusions of isotopes and indirect calorimetry, we assessed protein, glucose, and fat kinetics in severely ill surgical patients suffering from sepsis, major trauma, gastrointestinal cancer, or nutritional depletion from benign disease. We also assessed the effect of 5 days of total parenteral nutrition (TPN) on abnormal metabolism in these states. In the basal state, patients with sepsis, trauma, or cancer had an elevated rate of net protein catabolism due to an increased rate of whole-body protein catabolism, whereas whole-body protein synthesis was not impaired. TPN had no impact on the elevated rate of whole-body protein catabolism in these conditions but decreased the rate of net protein catabolism, suggesting that increased substrate availability optimizes whole-body protein synthesis. Consequently, few surgical patients became anabolic while receiving TPN. In contrast, patients with nutritional depletion from benign disease had a decreased rate of net protein loss compared with volunteers and could be made anabolic with the administration of TPN. All patients studied had an elevated rate of plasma glucose production, impaired glucose oxidation, and an increased rate of Cori cycling in the basal state. After 5 days of TPN, most surgical patients showed improved ability to oxidize glucose, but the high rates of glucose recycling to lactate persisted. Patients suffering from sepsis, trauma, or cancer had an enhanced rate of lipolysis in the basal state associated with an increased rate of whole body-fat oxidation compared with healthy volunteers. After administration of TPN, whole-body fat oxidation was significantly decreased in patients with trauma but increased in patients with sepsis or cancer.(ABSTRACT TRUNCATED AT 250 WORDS)
