Abstract
Despite complete resection, cancer recurrence frequently occurs in clinical practice. This indicates that cancer cells had already metastasized from their organ of origin at the time of resection or had circulated throughout the body via the lymphatic and vascular systems. To obtain this potential for metastasis, cancer cells must undergo essential and intrinsic processes that are supported by the tumor microenvironment. Cancer-associated inflammation may be engaged in cancer development, progression, and metastasis. Despite numerous reports detailing the interplays between cancer and its microenvironment via the inflammatory network, the status of cancer-associated inflammation remains difficult to recognize in clinical settings. In the current paper, we reviewed clinical reports on the relevance between inflammation and cancer recurrence after surgical resection, focusing on inflammatory indicators and cancer recurrence predictors according to cancer type and clinical indicators.

Abstract
Debate on appropriate triggers for transfusion of allogeneic blood products and their effects on short- and long-term survival in surgical and critically ill patients continue with no definitive evidence or decisive resolution. Although transfusion-related immune modulation (TRIM) is well established, its influence on immune competence in the recipient and its effects on cancer recurrence after a curative resection remains controversial. An association between perioperative transfusion of allogeneic blood products and risk for recurrence has been shown in colorectal cancer in randomized trials; whether the same is true for other types of cancer remains to be determined. This article focuses on the laboratory, animal, and clinical evidence to date on the mechanistic understanding of inflammatory and immune-modulatory effects of blood products and their significance for recurrence in the cancer surgical patient.

Abstract
BACKGROUND Intraoperative autotransfusion (IOAT) has been avoided in oncologic surgery because of possible tumor cell dissemination. Through a prior Phase I study, we demonstrated that malignant cells are not present in blood filtered for IOAT. We hypothesized that autotransfusion could be safely used for patients undergoing major oncologic procedures and reduce the need for allogeneic blood. MATERIALS AND METHODS A Phase II, IRB-approved, prospective evaluation was conducted of patients undergoing gastrointestinal oncologic procedures. All procedures were conducted with blood salvaged for IOAT, and the collected volume was autotransfused if it was >100 ml. Quality of life (QoL) was assessed by questionnaire at regular intervals. RESULTS A total of 92 patients were enrolled with median age of 56 years. The most commonly performed procedures were hepatectomy (47%) and pancreaticoduodenectomy (26%). The median preoperative hemoglobin (Hgb) was 13.1 (range, 9-16), and the median estimated blood loss was 350 ml (range, 20-4000 ml). Of the 92 total patients, 32 (35%) received IOAT with a median volume of 255 ml (range, 117-1499 ml). Multivariate analysis identified that patients with preoperative Hgb >11 g/dl (P = .02), and blood loss of 400-900 ml (P = .03) benefited from IOAT with a reduction in postoperative blood transfusion rate. Patients with discharge Hgb >10 g/dl showed higher mean QoL scores throughout their recovery. At a median follow-up of 18 months, the rates of recurrence in the IOAT and the non-IOAT groups were equivalent (38 vs. 39%, P = .9). CONCLUSIONS Intraoperative autotransfusion can be used safely and effectively for major oncologic procedures. Furthermore, degree of discharge anemia is associated with lower quality of life in patients undergoing oncologic gastrointestinal surgery.

Abstract
An evolving understanding of the consequences of allogeneic blood transfusion and escalating costs of providing allogeneic blood have resulted in an interest in blood management. Understanding the consequences of allogeneic transfusion includes a recognition of the immunosuppressive effects of allogeneic transfusion, a growing awareness of transfusion-related acute lung injury, and a rediscovery of transfusion-associated circulatory overload. More recently, interest has focused on the effect of stored blood on patient outcome. Although this discussion is not all-inclusive, it is intended to show that many techniques can be applied to decrease the exposure to allogeneic blood.

Abstract
BACKGROUND Hepatectomy and pancreatectomy are often associated with significant intraoperative blood loss leading to postoperative anemia, which has been demonstrated to lead to increased perioperative morbidity, a prolonged hospital stay, and decreased overall survival. Cancer has remained an absolute contraindication to autotransfusion because of the unproven concern about reinfusion of malignant cells. Thus, the aim of this study was to test for the presence of malignant cells in autotransfused filtered blood in patients undergoing major pancreatic and liver resection. METHODS A prospective study of 20 consecutive patients evaluated the presence of malignant cells from autotransfusion filtered blood after resection by flow cytometric and immunohistochemical methods. RESULTS Ten patients underwent major hepatectomy for metastatic colorectal cancer, with a median blood loss of 500 mL (range, 200-700 mL). Three patients received a total of six units of packed red blood cells. Ten patients underwent pancreaticoduodenectomy for adenocarcinoma with a median blood loss of 400 mL (range, 200-1300 mL). Five patients received a total of nine units of packed red blood cells. Flow cytometry did not demonstrate the presence of any cytokeratin-positive carcinoma cells in filtered blood. CONCLUSIONS Intraoperative autotransfusion for major hepatectomy in metastatic colorectal cancer and pancreatectomy for adenocarcinoma is safe and should begin to be evaluated in a phase II study for efficacy.

Abstract
In the perioperative period, blood transfusions are most commonly administered to address acute blood loss resulting from trauma, neoplasia, or surgery. In this setting, transfusions may be life saving, allowing time for clotting or surgical hemostasis. In recent years, however, there is a growing awareness that the administration of blood products may not be a benign treatment. In addition to the more commonly cited complications such as transfusion reactions, disease transmission, and electrolyte disturbances, blood transfusions have also been linked to poor surgical outcomes, increased risk of infection, cancer recurrence, and acute lung injury. The recognition of these problems has lead to more conservative transfusion strategies, and questioning of what constitutes an appropriate transfusion trigger. In this section, we will discuss the pathophysiology of acute blood loss, the benefits and risks of transfusions in surgical patients, management of perioperative blood transfusions, and alternative strategies to minimize the need for blood products.

Abstract
Deep hypothermic cardiopulmonary bypass with or without circulatory arrest has been used to facilitate the surgical repair of complex cerebrovascular lesions. The advantages of deep hypothermia have been tempered by the occurrence of coagulopathy that is associated with substantial morbidity and mortality. This study analyzed retrospectively the records of 13 patients who underwent cerebrovascular neurosurgery using deep hypothermic cardiopulmonary bypass with or without circulatory arrest during the period 1993 through 1999. All patients received the serine protease inhibitor aprotinin in an effort to avoid the development of a coagulopathy, defined as hemorrhage requiring reoperation. No patients developed postoperative intracranial hemorrhage. There was also no evidence of renal dysfunction, deep venous thrombosis, myocardial infarction, or pulmonary embolism. In conclusion, this study suggests that aprotinin may be beneficial to avoid the coagulopathy that is more likely to occur if deep hypothermic cardiopulmonary bypass with or without circulatory arrest is used for craniotomy without adverse effects on renal function or apparent thrombotic complications.

Abstract
BACKGROUND AND PURPOSE This study reviews the perioperative use of red blood cell transfusion in cerebrovascular neurosurgery. The current algorithm for preoperative ordering of red cells is historical and dated. More blood is ordered than is actually transfused, and considerable variability exists between different institutions. We determine the use of blood transfusion in cerebrovascular surgery to develop a rational blood ordering practice. METHODS Records of 301 patients undergoing cerebrovascular neurosurgery at the University of Virginia were reviewed to quantitatively evaluate red blood cell transfusion practices. The amount and reason for transfusion were noted in each case. RESULTS In 126 patients undergoing carotid endarterectomy, there were no preoperative or intraoperative transfusions and 5 postoperative transfusions (4.0%). In 71 ruptured aneurysm patients, there were 2 preoperative blood transfusions (2.8%), 4 intraoperative transfusions (5.6%), and 15 postoperative transfusions (21.1%). Forty-seven patients underwent surgery for unruptured aneurysms, with no preoperative transfusions, 2 intraoperative transfusions (4.3%), and 8 postoperative blood transfusions (17.0%). Of the 54 patients undergoing surgery for arteriovenous malformations, 5 patients (9.3%) were transfused preoperatively, 4 were transfused intraoperatively (7.4%), and 22 were transfused postoperatively (40.7%). None of the 3 patients undergoing surgery for concomitant arteriovenous malformations and aneurysms received intraoperative blood transfusions, but 1 received blood both preoperatively and postoperatively, and another received a transfusion postoperatively only. The overall ratio of perioperative cross-match to transfusion in this series is 41.4. CONCLUSIONS In vascular neurosurgery at our institution, blood has routinely been ordered excessively. We recommend an ABO-Rh type and antibody screen for aneurysm and arteriovenous malformation surgery and no screen for carotid endarterectomy to efficiently utilize transfusion therapy in cerebrovascular surgery.

Abstract
BACKGROUND Alternatives to allogeneic blood transfusion exist and are being used to varying extents in Australian hospitals. Evidence on effectiveness and cost-effectiveness is generally inconclusive and provides a suboptimal basis for policy development. AIM To describe the influences on uptake of transfusion technologies as perceived by national and institutional stakeholders. METHODS Qualitative interview study. Interview transcripts were coded and analysed independently by at least two researchers. Participants had opportunity to comment on their transcript and the manuscript. RESULTS A total of 71 interviews were conducted with representatives of the media, specialist medical societies, consumer special interest groups, the Australian Red Cross Blood Service (ARCBS), government, private health insurers, technology manufacturers, prominent clinicians in the area and a sample of clinicians drawn from hospitals with variable use of blood-saving technologies. Technical advances and acceptance of lower transfusion triggers were identified as the main influences on the decrease in use of allogeneic blood transfusion in the past decade. Participants indicated that patients were most aware and supportive of autologous predonation. Participants noted that 'enthusiasts' were involved in educating about the need for alternatives, negotiating resourcing and maintaining the use of a technology. Funding mechanisms were seen as main barriers to use of alternatives. A discrepancy was noted in the rigour of evaluation and regulation of pharmaceuticals and devices/procedures. CONCLUSIONS Uptake of blood transfusion technologies by institutions was dependent mostly on funding arrangements and the presence of an 'enthusiast'. Critical review of the evidence for effectiveness or cost-effectiveness of these technologies was rarely mentioned. Opportunities exist for evidence-based medicine principles to play a greater role in policy decisions in this area.

Abstract
PURPOSE To determine whether salvaged autologous blood collected postoperatively contains complement split products (SC5b-9), and pro-inflammatory cytokines (IL-6 and IL-8) and whether there are any differences between blood collected during hip or knee surgery. METHODS Fifty-eight consecutive patients undergoing hip or knee replacement surgery were studied. Thirty-eight had postoperative bleeding large enough to require infusion of salvaged blood. The salvaged blood was filtered during collection through a 200 microm filter and before infusion a 40 microm filter was used. Samples for complement and cytokine determinations were drawn from the circulation and from the collected blood. RESULTS High concentrations of SC5b-9, IL-6, and IL-8 were found in salvaged blood. The concentrations were higher than in the circulation (P < 0.05). The circulating concentrations of IL-6 and IL-8 were increased 60 min and 12-18 hr after transfusion. There were no differences regarding SC5b-9, IL-6, and IL-8 in the blood collected after hip or knee surgery. CONCLUSION Blood collected from a surgical wound contains large concentrations of inflammatory mediators. There were no differences between blood collected during hip or knee surgery.

Abstract
Orthopedic surgery is a common procedure among the elderly, and patients are at risk of receiving unnecessary blood transfusions. The goals of this project were to analyze current transfusion practices, identify opportunities for improvement, implement hospital-based quality improvement programs, and measure their impact on transfusion practices. Our aims were to decrease unnecessary transfusions and overall exposure to blood products. Data were abstracted from medical records, at baseline and postintervention. The results demonstrated significant improvements: a 55% decrease in avoidable transfusion events (from 42% to 19%, p < .001) and a decrease in the pre-transfusion hematocrit from a baseline of 29% to 26.9% in the postintervention period (p < .01). The percentage of single unit transfusion events increased from 71.9% to 77.2% (p = .05). These results suggest that the interventions had a significant impact on the use of blood. In the long term, these results should translate into cost savings and improved patient outcomes.

Abstract
PURPOSE Utilization report cards are commonly used to assess hospitals. However, in practice, they rarely account for differences in patient populations among hospitals. Our study questions were: (1) How does transfusion utilization for hip fracture patients vary among hospitals? (2) What patient characteristics are associated with transfusion and how do those characteristics vary among hospitals? (3) Is the apparent pattern of variation of utilization among hospitals altered by controlling for these patient characteristics? SUBJECTS AND METHODS We included consecutive hip fracture patients aged 60 years or older who underwent surgical repair between 1982 and 1993 in 19 hospitals from four states, excluding those who refused blood transfusion, had multiple trauma, metastatic cancer, multiple myeloma, an above the knee amputation, or were paraplegic or quadriplegic. The outcome of interest was postoperative blood transfusion. "Trigger hemoglobin" was the lowest hemoglobin recorded before transfusion or recorded at any time during the week before or after surgery for patients who were not transfused. RESULTS There was considerable variation in transfusion among hospitals postoperatively (range 31.2% to 54.0%, P = 0.001). Trigger hemoglobin also varied considerably among hospitals. In unadjusted analyses, four of nine teaching and two of nine nonteaching hospitals had postoperative transfusion rates significantly higher than the reference (teaching) hospital, while one nonteaching hospital had a lower rate. In an analysis controlling for trigger hemoglobin and multiple clinical variables, one of nine teaching and four of nine nonteaching hospitals had rates higher than the reference hospital, while four teaching hospitals and one nonteaching hospital had lower rates. CONCLUSIONS The apparent pattern of variation of transfusion among hospitals varies according to how one adjusts for relevant patient characteristics. Utilization report cards that fail to adjust for these characteristics may be misleading.

Abstract
This retrospective review analyzed and compared transfusion practices in patients undergoing orthopedic surgery in five Massachusetts hospitals with current practice guidelines; opportunities for improvement were identified. Patient-specific clinical information and data about transfusion practices were obtained from the medical records of 384 Medicare patients undergoing orthopedic surgery between January 1992 and December 1993. The number of patients who donated autologous blood preoperatively differed significantly among hospitals as did the number of autologous units that were unused. The number of blood units transfused at each transfusion event also differed significantly; some surgeons transfused > or =2 units in the majority of their patients, while others transfused 1 unit at a time. This variation in practice was not explained by differences in patients' clinical status. The mean pretransfusion hematocrit was higher for autologous versus allogeneic blood, suggesting more liberal criteria to transfuse autologous blood. Nearly half of all transfusion events were determined to have been potentially avoidable. Avoidable transfusions were also three to seven times more likely with autologous than with allogeneic blood. Significant inter-hospital differences existed in the number of elective surgery patients exposed to allogeneic blood. The major determinant of allogeneic blood use in these patients was the availability of autologous blood. Each additional autologous blood unit available decreased the odds of allogeneic blood exposure twofold. Differences in intraoperative and postoperative blood salvage use also were noted. These findings indicate that significant variations in practice exist. Comparative data enabled hospitals to identify and target specific areas for improvement.

Abstract
Blood conservation has evolved into an important issue in hospital-based medicine. Increased awareness of and worry about transfusion-associated diseases have prompted a focus on this important area. New technologies, including continuous intraarterial monitoring devices, microchemical technologies, new drug development (recombinant human erythropoietin and aprotinin) and intraoperative salvage techniques have made the concept of clinically important blood conservation possible. In this article, the authors review clinically important areas regarding blood conservation, which are subsequently detailed in this issue of AACN Clinical Issues. Emphasis is placed on the need for blood conservation in acute and critical care practice and the technologies available to achieve this goal.

Abstract
Transfusion of homologous blood is associated with significant and well-known risks. Reported transfusion rates for pediatric patients undergoing surgical correction of synostotic calvarial sutures vary between 20 and 500% of estimated blood volume. The objective of this study was to ascertain the risks, benefits, and effects on transfusion rates associated with the use of intraoperative autologous transfusion (IAT) in this patient population. The Haemonetics Cell Saver 4 (Haemonetics Corporation, Braintree, MA) autotransfusion system was used to salvage blood in 18 patients undergoing the release of stenosed calvarial sutures. In a prospective, nonrandomized study, these patients were compared with a control group of similar age, gender, weight, and surgical procedures. There were 10 male patients and 8 female patients; the mean age was 7.2 months, the mean weight was 8.67 kg, and the mean surgical time was 3.15 hours. The mean amount of homologous blood transfused to the control group was 189 ml, compared with 87.69 ml for the IAT group, which was a decrease of 46.3%. The mean amount of autologous blood transfused was 150 ml (range, 50-250 ml). Thirty-three percent of the patients in the IAT group did not require homologous blood transfusion. No complications were observed with the use of the Cell Saver in the IAT group. The use of the Cell Saver was associated with a significant decrease in the amount and rate of homologous blood transfusions. Its use appears to be safe in pediatric patients undergoing craniosynostotic surgery.
