Effect of perioperative autologous versus allogeneic blood transfusion on the immune system in gastric cancer patients

Background： Allogeneic blood transfusion-induced immunomodulation （TRIM） and its adverse effect on the prognosis of patients treated surgically for cancer remain complex and controversial. However, the potential risk associated with allogeneic blood transfusion has heightened interest in the use of autologous blood transfusion. In the present study, the serum concentrations of neopterin, interferon-gamma （IFN-γ）, T lymphocyte subsets （CD3^＋, CD4^＋, CD8^＋, CD4^＋/CD8^＋） and a possible association between these variables were investigated. The purpose was to further evaluate the effect of autologous versus allogeneic blood transfusion on immunological status in patients undergoing surgery for gastric cancer. Methods： Sixty ASA Ⅰ～Ⅱ（American Society of Anesthesiologists） patients undergoing elective radical resection for stomach cancer were randomly allocated to receive either allogeneic blood transfusion （n=30） or autologous blood transfusion （n=30）. Serum concentrations of the neopterin, IFN-γ and T lymphocyte subsets in the recipients were measured before induction of anesthesia, after operation, and on the 5th postoperative day. Results： Both two groups, serum neopterin, IFN-γ, percentages of T-cell subsets （CD3^＋, CD4^＋）, and CD4^＋/CD8^＋ ratio had significantly decreased after operation, but decreased more significantly in group H （receiving allogeneic blood transfusion） than those in group A （receiving autologous whole blood transfusion） （P〈0.05）. On the 5th postoperative day,serum neopterin, IFN-γ, CD3^＋, CD4^＋ T-cells, and CD4^＋/CD8^＋ ratio returned to the baseline values in group A. In contrast, the above remain decreasing in group H, where there were no significant relations between serum neopterin and IFN-γ. Conclusion：Perioperative surgical trauma and stress have an immunosuppressive impact on gastric cancer patients. Allogeneic blood transfusion exacerbates the impaired immune response. Autologous blood transfusion might be significantly beneficial for immune-compromised patients in the perioperative period, clearly showing its superiority over allogeneic blood transfusion.

Advantage of autologous blood transfusion in surgery for hepatocellular carcinoma

AIM: To evaluate the significance of autologous blood transfusion (AT) in reducing homologous blood transfusion (HT) in surgery for hepatocellular carcinoma (HCC). METHODS: The proportion of patients who received HT was compared between two groups determined by the time of AT introduction; period A (1991-1994, n = 93) and period B (1995-2000, n = 201). Multivariate logistic regression analysis was performed in order to identify independent significant predictors of the need for HT. We also investigated the impact of AT and HT on long-term postoperative outcome after curative surgery for HCC. RESULTS: The proportion of patients with HT was significantly lower in period B than period A (18.9% vs 60.2%, P < 0.0001). Multivariate logistic regression analysis identified AT administration as a significant independent predictor of the need for HT (P < 0.0001). Disease-free survival in patients with AT was comparable to that without any transfusion. Multivariate analysis identified HT administration as an independent significant factor for poorer disease-free survival (P = 0.0380). CONCLUSION: AT administration significantly decreased the need for HT. Considering the postoperative survival disadvantage of HT, AT administration could improve the long-term outcome of HCC patients.

Effect of autologous blood donation on the central venous pressure, blood loss and blood transfusion during living donor left hepatectomy

AIM： Autologous blood donation （ABD） is mainly used to reduce the use of banked blood. In fact, ABD can be regarded as acute blood loss. Would ABD 2-3 d before operation affect the CVP level and subsequently result in less blood loss during liver resection was to be determined.METHODS： Eighty-four patients undergoing living donor left hepatectomy were retrospectively divided as group Ⅰ （GⅠ） and group Ⅱ （GⅡ） according to have donated 250-300 mL blood 2-3 d before living donor hepatectomy or not. The changes of the intraoperative CVP, surgical blood loss,blood products used and the changes of perioperative hemoglobin （Hb） between groups were analyzed and compared by using Mann-Whitney Utest.RESULTS： The results show that the intraoperative CVP changes between GⅠ （n = 35） and GⅡ （n = 49） up to graft procurement were the same, subsequently the blood loss,but ABD resulted in significantly lower perioperative Hb levels in GI.CONCLUSION： Since none of the patients required any blood products perioperatively, all the predonated bloods were discarded after the patients were discharged from the hospital. It indicates that ABD in current series had no any beneficial effects, in term of cost, lowering the CVP, blood loss and reduce the use of banked blood products, but resulted in significant lower Hb in perioperative period.

Observation on the Efficacy of Autologous Blood Transfusion Combined with Controlled Hypotension in Patients with Spinal Internal Fixation during the Outbreak of New Coronavirus Pneumonia in Western Guangxi (in Guixi)

Objective: To explore the therapeutic effect of autologous blood reinfusion combined with controlled hypotension in surgical spinal fixation during the outbreak of COVID-19. Methods: 30 patients with spinal internal fixation autologous blood transfusion combined with controlled hypotension were selected as the subjects during the epidemic period from December 2019 to June 2020 in our hospital and during the operation, on the basis of routine blood pressure reduction, the American Haemonetice Corporation autologous blood continuous reinfusion system was used to infuse the blood recovered during the operation to the patient through filtration and other procedures. Results: 30 patients had no complications such as fever and hemolysis;And after the operation, the tube was dialed according to the drainage volume, the cervical thoracic and lumbar brace was customized, and the patient walked on the ground for one week;After no abnormalities, the patient was discharged. Intraoperative comparison of white blood cells (WBC), red blood cells (RBC), red blood cell pressure (HCT), hemoglobin (HGB), and coagulation time (PT) of patients with autologous blood before and after transfusion showed statistically significant differences before and after surgery (P < 0.001). Conclusion: During the new coronavirus pneumonia epidemic, the internal fixation of spinal surgery used a recovery machine to collect intraoperative blood for reinfusion. Intraoperative antihypertensive drugs were used to control blood pressure within a certain safe range. The postoperative clinical observation effect was significant and safe;especially at present the clinical significance during the epidemic was significant.

Effect of Point-of-care Hemoglobin/Hematocrit Devices and Autologous Blood Salvage on Reduction of Perioperative Allogeneic Blood Transfusion

Objective To evaluate the effect of point-of-care hemoglobin/hematocrit(POC HGB/HCT) devices and intraoperative blood salvage on the amount of perioperative allogeneic blood transfusion and blood conservation in clinical practice. Methods A total of 46 378 medical records of 22 selected hospitals were reviewed. The volume of allogeneic red blood cell and plasma, number of patients transfused, number of intraoperative autologous blood salvage, total volume of autologous blood transfusion, and amount of surgery in the year of 2011 and 2013 were tracked. Paired t-test was used in intra-group comparison, while t-test of two isolated samples carried out in inter-group comparison. P<0.05 was defined as statistically significant difference. Results In the hospitals where POC HGB/HCT device was used(n=9), the average allogeneic blood transfusion volume per 100 surgical cases in 2013 was significantly lower than that in 2011(39.86±20.20 vs. 30.49±17.50 Units, t=3.522, P=0.008). In the hospitals without POC HGB/HCT meter, the index was not significantly different between 2013 and 2011. The average allogeneic blood transfusion volume was significantly reduced in 2013 than in 2011 in the hospitals where intraoperative autologous blood salvage ratio [autologous transfusion volume/(autologous transfusion volume+allogeneic transfusion volume)] was increased(n=12, t=2.290, P=0.042). No significant difference of the above index was found in the hospitals whose autologous transfusion ratio did not grow. Conclusion Intraoperative usage of POC HGB/HCT devices and increasing autologous transfusion ratio could reduce perioperative allogeneic blood transfusion.

Clinical nursing value of predictive nursing in reducing complications of pregnant women undergoing short-term massive blood transfusion during cesarean section

BACKGROUND Cesarean hemorrhage is one of the serious complications,and short-term massive blood transfusion can easily cause postoperative infection and physical stress response.However,predictive nursing intervention has important clinical significance for it.AIM To explore the effect of predictive nursing intervention on the stress response and complications of women undergoing short-term mass blood transfusion during cesarean section(CS).METHODS A clinical medical record of 100 pregnant women undergoing rapid mass blood transfusion during sections from June 2019 to June 2021.According to the different nursing methods,patients divided into control group(n=50)and observation group(n=50).Among them,the control group implemented routine nursing,and the observation group implemented predictive nursing intervention based on the control group.Moreover,compared the differences in stress res-ponse,complications,and pain scores before and after the nursing of pregnant women undergoing rapid mass blood transfusion during CS.RESULTS The anxiety and depression scores of pregnant women in the two groups were significantly improved after nursing,and the psychological stress response of the observation group was significantly lower than that of the control group(P<0.05).The heart rate and mean arterial pressure(MAP)of the observation group during delivery were lower than those of the control group,and the MAP at the end of delivery was lower than that of the control group(P<0.05).Moreover,different pain scores improved significantly in both groups,with the observation group considerably less than the control group(P<0.05).After nursing,complications such as skin rash,urinary retention,chills,diarrhea,and anaphylactic shock in the observation group were 18%,which significantly higher than in the control group(4%)(P<0.05).CONCLUSION Predictive nursing intervention can effectively relieve the pain,reduce the incidence of complications,improve mood and stress response,and serve as a reference value for the nursing of women undergoing rapid mass transfusion during CS.

Survey on Blood Transfusion Practices among Medical and Paramedical Staff in the Pediatric Unit of the Mohammed VI University Hospital in Marrakesh, Morocco

Blood transfusion is a complex activity, involving many actors. As a high-risk activity, it necessitates the implementation of specific methods for effective control. The safety of blood transfusion is significantly influenced by the beliefs of healthcare workers and organizational factors, constituting two major considerations. We conducted a cross-sectional, descriptive, and analytical survey to examine the knowledge and practices related to transfusion among the medical and paramedical staff at the Pediatric Department (Mother-Child) of CHU Mohammed VI from September 1, 2022, to December 31, 2022. Among the 135 staff members interviewed, only 41% had received training in blood transfusion. A majority (65.2%) of the staff noted that a mismatch in cross-matching led to transfusion complications. Two-thirds (66.7%) identified chills as the primary clinical sign of potential accidents. Regarding elements to monitor during a reaction, hemolysis (78.5%) and temperature (76.3%) were most commonly mentioned. Surprisingly, more than half (53.3%) of the personnel interviewed did not conduct post-transfusion monitoring. This survey highlighted significant deficiencies in knowledge and practices related to transfusion. To address these issues, we recommend implementing guidelines and providing tailored training for the staff, aiming to rectify these deficiencies and enhance overall practices.

The Impact of Blood Transfusion on the Efficiency of Stem Cell Transplants

Background: While blood product transfusion is essential for managing hematologic deficits in Allogenic Hematopoietic stem cell transplant (AHSCT) recipients, it has risks including infectious disease transmission, alloimmunization, and transfusion reactions. These risks have sparked an ongoing debate regarding the overall impact of transfusions on patient outcomes. Thus, this study aimed to evaluate the impact of Red Blood Cells (RBCs) and/or platelet transfusion on the infection incidence and overall survival in AHSCT patients. Methods: We performed a retrospective analysis of clinical and laboratory data of sixty adult patients with primary malignant hematological disorder who had undergone AHSCT. Participants’ data were categorized into two groups;Group 1 (low transfusion group) consisted of patients receiving 10 units. Quantitative data were expressed as mean ± SD. The t-test of significance and Chi-square (χ2) test were used, with p ≤ 0.05 considered significant. Result: A total of 60 patients’ data was included. In Group 1, out of 30 patients, 13 (43.33%) developed infections. In contrast, Group 2 had 21 (70%) out of 30 patients develop infections. Group 1 had a higher survival rate (57.8%) than Group 2 (transfusion > 10 units) (46.2%) with a chi-square value = 23.56, and p-value Conclusion: The volume of blood product transfusions has a considerable impact on patient outcomes, particularly infection and survival rates. Additional long-term prospective studies and larger randomized controlled trials are needed to strengthen the evidence for determining transfusion protocols for these patients.

The Effect of the Direct Anti-Human Globulin Test on the Clinical Outcome of Patients Receiving Blood Transfusion

Objective:To study the effect of the direct anti-human globulin test on the clinical efficacy of blood transfusion patients.Methods:52 transfused patients were selected for this study,of which 26 cases with positive direct anti-human globulin tests were included in the positive group,and another 26 cases with negative direct anti-human globulin tests were included in the negative group.The apparent efficacy of the patients in the two groups after blood transfusion was compared.Results:After blood transfusion,the apparent efficacy of the negative group was significantly higher,P<0.05;in the positive group,the proportion of the predominantly multi-antibody group was the highest;after blood transfusion,the post-transfusion apparent efficacy of the simple IgG group was higher than that of the multi-antibody group,P<0.05;comparing the intensity of the different antibodies resulted in the 1+group,and the 3+to 4+groups were significantly lower after blood transfusion,P<0.05.Conclusion:The use of the direct antiglobulin test in transfused patients showed that patients with positive results would have better clinical efficacy.Direct anti-human globulin tests will have an impact on the clinical efficacy of blood transfusion in patients with positive results,so it is very important to carry out a direct anti-human globulin test on blood transfusion patients.

Refractory lipoatrophy treated with autologous whole blood injection:A case report

BACKGROUND Intramuscular corticosteroid injection may cause adverse effects such as dermal and/or subcutaneous atrophy,alopecia,hypopigmentation,and hyperpigmentation.Although cutaneous atrophy can spontaneously resolve,several treatment options have been suggested for this condition.CASE SUMMARY In this paper,we report a case of corticosteroid injection induced lipoatrophy treated with autologous whole blood(AWB)injection,as the condition had been unresponsive to fractional laser therapy.A 29-year-old female patient visited the dermatology clinic complaining of skin depression on her right buttock area,which had appeared six months earlier.There had been only subtle improvement at the margins after fractional CO2 laser treatment;therefore,after obtaining informed consent from the patient,AWB treatment was initiated.One month after the first AWB injection,the size and depth of the lesion had noticeably improved,and a slight improvement was also observed in discoloration.CONCLUSION Close observation is the initial treatment of choice for steroid induced skin atrophy;however,for patients in need of immediate cosmetic improvement,AWB injection may be a safe and cost-effective alternative.

Machine Learning for Detecting Blood Transfusion Needs Using Biosignals

Adequate oxygen in red blood cells carrying through the body to the heart and brain is important to maintain life.For those patients requiring blood,blood transfusion is a common procedure in which donated blood or blood components are given through an intravenous line.However,detecting the need for blood transfusion is time-consuming and sometimes not easily diagnosed,such as internal bleeding.This study considered physiological signals such as electrocardiogram(ECG),photoplethysmogram(PPG),blood pressure,oxygen saturation(SpO2),and respiration,and proposed the machine learning model to detect the need for blood transfusion accurately.For the model,this study extracted 14 features from the physiological signals and used an ensemble approach combining extreme gradient boosting and random forest.The model was evaluated by a stratified five-fold crossvalidation:the detection accuracy and area under the receiver operating characteristics were 92.7%and 0.977,respectively.

Risk factors for blood transfusion and its prognostic implications in curative gastrectomy for gastric cancer

BACKGROUND Gastric cancer(GC)is still a prevalent neoplasm around the world and its main treatment modality is surgical resection.The need for perioperative blood transfusions is frequent,and there is a long-lasting debate regarding its impact on survival.AIM To evaluate the factors related to the risk of receiving red blood cell(RBC)transfusion and its influence on surgical and survival outcomes of patients with GC.METHODS Patients who underwent curative resection for primary gastric adenocarcinoma at our Institute between 2009 and 2021 were retrospectively evaluated.Clinicopathological and surgical characteristics data were collected.The patients were divided into transfusion and non-transfusion groups for analysis.RESULTS A total of 718 patients were included,and 189(26.3%)patients received perioperative RBC transfusion(23 intraoperatively,133 postoperatively,and 33 in both periods).Patients in the RBC transfusions group were older(P<0.001),and had morecomorbidities(P=0.014),American Society of Anesthesiologists classification III/IV(P<0.001),and lower preoperative hemoglobin(P<0.001)and albumin levels(P<0.001).Larger tumors(P<0.001)and advanced tumor node metastasis stage(P<0.001)were also associated with the RBCtransfusion group.The rates of postoperative complications(POC)and 30-d and 90-d mortalitywere significantly higher in the RBC transfusion group than in the non-transfusion group.Lowerhemoglobin and albumin levels,total gastrectomy,open surgery,and the occurrence of POC werefactors associated with the RBC transfusion.Survival analysis demonstrated that the RBCtransfusions group had worse disease-free survival(DFS)and overall survival(OS)compared withpatients who did not receive transfusion(P<0.001 for both).In multivariate analysis,RBCtransfusion,major POC,pT3/T4 category,pN+,D1 lymphadenectomy,and total gastrectomywere independent risk factors related to worse DFS and OS.CONCLUSIONPerioperative RBC transfusion is associated with worse clinical conditions and more advancedtumors.Further,it is an independent factor related to worse survival in the curative intentgastrectomy setting.

The Place of Blood Transfusion in the Management of Obstetric Emergencies in the Gynaecology and Obstetrics Department of the Reference Health Center of Fana (Mali)

This is a prospective and descriptive study carried out at the gynecology and obstetrics department of the reference health center of Fana from 01 May 2019 to 30 November or 7 months. The main objective was to study the role of blood transfusion in the management of obstetric emergencies. During the study period we recorded 434 cases of obstetric emergencies of which 116 cases required an emergency blood transfusion or 26.73%. The most frequently found indications for blood transfusion are hemorrhages of the immediate postpartum 46.6% followed by severe malaria on pregnancy 27.6%. Blood remains the most prescribed and available Labile blood product in the department. Maternal prognosis was improved in 92.2%.

Impact of perioperative blood transfusion on oncological outcomes in ampullary carcinoma patients underwent pancreaticoduodenectomy

BACKGROUND The effect of perioperative blood transfusion(PBT)on the prognosis of ampullary carcinoma(AC)is still debated.AIM To explore the impact of PBT on short-term safety and long-term survival in AC patients who underwent pancreaticoduodenectomy.METHODS A total of 257 patients with AC who underwent pancreaticoduodenectomy between 1998 and 2020 in the Cancer Hospital,Chinese Academy of Medical Sciences,were retrospectively analyzed.We used Cox proportional hazard regression to identify prognostic factors of overall survival(OS)and recurrencefree survival(RFS)and the Kaplan-Meier method to analyze survival information.RESULTS A total of 144(56%)of 257 patients received PBT.The PBT group and nonperioperative blood transfusion group showed no significant differences in demographics.Patients who received transfusion had a comparable incidence of postoperative complications with patients who did not.Univariable and multivariable Cox proportional hazard regression analyses indicated that transfusion was not an independent predictor of OS or RFS.We performed Kaplan-Meier analysis according to subgroups of T stage,and subgroup analysis indicated that PBT might be associated with worse OS(P<0.05)but not RFS in AC of stage T1.CONCLUSION We found that PBT might be associated with decreased OS in early AC,but more validation is needed.The reasonable use of transfusion might be helpful to improve OS.

Effect of perioperative blood transfusion on clinical outcomes in hepatic surgery for cancer

Allogeneic blood transfusion during liver resection for malignancies has been associated with an increased incidence of different types of complications: infectious complications, tumor recurrence, decreased survival. Even if there is clear evidence of transfusion-induced immunosuppression, it is difficult to demonstrate that transfusion is the only determinant factor that decisively affects the outcome. In any case there are several motivations to reduce the practice of blood transfusion. The advantages and drawbacks of different transfusion alternatives are reviewed here, emphasizing that surgeons and anesthetists who practice in centers with a high volume of liver resections, should be familiar with all the possible alternatives.

Blood transfusion for the treatment of acute anaemia in inflammatory bowel disease and other digestive diseases

Allogeneic blood transfusion (ABT) is frequently used as the first therapeutic option for the treatment of acute anaemia in patients with inflammatory bowel disease (IBD), especially when it developed due to gastrointestinal or perioperative blood loss, but is not risk-free. Adverse effects of ABT include, but are not limited to, acute hemolytic reaction (wrong blood or wrong patient), febrile non-hemolytic transfusional reaction, bacterial contamination, transfusion-related acute lung injury, transfusion associated circulatory overload, transfusion-related immuno-modulation, and transmission of almost all infectious diseases (bacteria, virus, protozoa and prion), which might result in increased risk of morbidity and mortality. Unfortunately, the main physiological goal of ABT, i.e. to increase oxygen consumption by the hypoxic tissues, has not been well documented. In contrast, the ABT is usually misused only to increase the haemoglobin level within a f ixed protocol [mostly two by two packed red blood cell (PRC) units] independently of the patient' s tolerance to normovolemic anaemia or his clinical response to the transfusion of PRC units according to a "one-by-one" administration schedule. Evidencebased clinical guidelines may promote best transfusion practices by implementing restrictive transfusion protocols, thus reducing variability and minimizing the avoidable risks of transfusion, and the use of autologous blood and pharmacologic alternatives. In this regard, preoperative autologous blood donation (PABD) consistently diminished the frequency of ABT, although its contribution to ABT avoidance is reduced when performed under a transfusion protocol. In addition, interpretation of utility of PABD in surgical IBD patients is hampered by scarcity of published data. However, the role of autologous red blood cells as drug carriers is promising. Finally, it must be stressed that a combination of methods used within wellconstructed protocols will offer better prospects for blood conservation in selected IBD patients undergoing elective surgery.

Perioperative blood transfusion decreases long-term survival in pediatric living donor liver transplantation

BACKGROUND The impact of perioperative blood transfusion on short-and long-term outcomes in pediatric living donor liver transplantation(PLDLT)must still be ascertained,mainly among young children.Clinical and surgical postoperative complications related to perioperative blood transfusion are well described up to three months after adult liver transplantation.AIM To determine whether transfusion is associated with early and late postoperative complications and mortality in small patients undergoing PLDLT.METHODS We evaluated the effects of perioperative transfusion on postoperative complications in recipients up to 20 kg of body weight,submitted to PLDLT.A total of 240 patients were retrospectively allocated into two groups according to postoperative complications:Minor complications(n=109)and major complications(n=131).Multiple logistic regression analysis identified the volume of perioperative packed red blood cells(RBC)transfusion as the only independent risk factor for major postoperative complications.The receiver operating characteristic curve was drawn to identify the optimal volume of the perioperative RBC transfusion related to the presence of major postoperative complications,defining a cutoff point of 27.5 mL/kg.Subsequently,patients were reallocated to a low-volume transfusion group(LTr;n=103,RBC≤27.5 mL/kg)and a high-volume transfusion group(HTr;n=137,RBC>27.5 mL/kg)so that the outcome could be analyzed.RESULTS High-volume transfusion was associated with an increased number of major complications and mortality during hospitalization up to a 10-year follow-up period.During a short-term period,the HTr showed an increase in major infectious,cardiovascular,respiratory,and bleeding complications,with a decrease in rejection complications compared to the LTr.Over a long-term period,the HTr showed an increase in major infectious,cardiovascular,respiratory,and minor neoplastic complications,with a decrease in rejection complications.Additionally,Cox hazard regression found that high-volume RBC transfusion increased the mortality risk by 3.031-fold compared to low-volume transfusion.The Kaplan-Meier survival curves of the studied groups were compared using log-rank tests and the analysis showed significantly decreased graft survival,but with no impact in patient survival related to major complications.On the other hand,there was a significant decrease in both graft and patient survival,with high-volume RBC transfusion.CONCLUSION Transfusion of RBC volume higher than 27.5 mL/kg during the perioperative period is associated with a significant increase in short-and long-term postoperative morbidity and mortality after PLDLT.

THE EFFECT OF SKIN GRAFTING AT DIFFERENT TIME POST BLOOD TRANSFUSION AND BONE MARROW TRANSPLANTATION ON RATS COMBINED RADIATION-BURN INJURY

After the rats were inflicted with 8 Gy total body gamma ray irradiation and 15 % total body surface area (TBSA) full thickness burn injury, they were treated with blood transfusion (BT) and bone marrow transplantation (BMT). Then the survival of allografts grafted on the escharectomized burn wounds in the 24, 48 and 72 h postinjury was observed. It was found that when the burn wounds were closed with allo- grafts in the 24h postinjury, there were an early elevation of leucocytes, the appearance of the donor’s cells and a significantly higher survival rate of the rats on the 30 day postinjury. The allografts could survive longer and wounds showed no signs of infection and healed quicker. When the allografts were grafted in the 48 h or 72 h postinjury, only harmful effects to hasten the death of rats were observed.

Influence of Perioperative Blood Transfusion on Prognosis in Patients with Colon Cancer

Objective： To explore the influence of perioperative blood transfusion on the postoperative survival of patients with colon cancer. Methods： Univariate and multivariate retrospective analyses were performed on the survival in a total of 723 colon cancer patients which were treated surgically during a period of 10 years. Results： Kaplan-Meier estimates showed that more than 800 mL perioperative blood transfusion was the survival predictor. Blood transfusion influenced significantly the prognosis of patients 40 years old and younger, those undergoing helicoloectomy left side, those with papillary adenocarcinoma, those with big tumors （diameter ≥ 8 cm）, those with stage Ⅰ tumors, those with lymphatic node metastases and those without liver metastases. In multivariate analysis only the tumor location, radicality of operation, lymphatic invasion, liver metastasis, depth of tumor invasion and TNM stage retained their significance. Conclusion： Perioperative blood transfusion is some extent. The indication of blood transfusion the prognostic factor for patients with colon cancer to must be restricted strictly, specially in patients younger than 40 years old, with right side lesion, papillary adenocarcinoma, big tumors （diameter ≥8 cm）, stage Ⅰ tumors and lymphatic node metastases or without liver metastases. But perioperative blood transfusion may not be deleterious for patients with staging Ⅳ disease and with distant metastases.
