Laparoscopic excision of duodenal schwannoma.

BACKGROUND: Benign duodenal tumours are rare and less common than malignant tumours. They comprise a wide variety of pathologies. Schwannoma is an ectodermal neoplasm arising from the nerve sheath that envelops axons. A duodenal location is extremely rare. Therapy consists in the radical excision of the tumour. Our aim was to describe a minimally invasive technique used for the excision of duodenal schwannoma, so that a laparotomy has been avoided. METHODS: A laparoscopic operation under general anaesthesia was undertaken with the patient in supine position with the legs abducted. No macroscopic peritoneal seedling was found. Therefore, a laparoscopic Kocher maneuver was performed. The retroperitoneum was entered using the harmonic scalpel and the dissection extended beyond the vena cava and the duodenum. The location and the size of the lesion have been confirmed using an intraoperative endoscopic ultrasound examination. The excision of the lesion was performed by use the harmonic scalpel. Then, the duodenal wall was sutured by use endoscopic stitches. The resected lesion was then placed in a retrieval bag and extracted through the port incision. Operating time was 300 min and blood loss 200 ml. RESULTS: The postoperative course was uneventful. Histological findings showed a benign schwannoma. CONCLUSIONS: The minimally invasive technique may be a valid alternative to open surgery in the treatment of benign duodenal tumors.

[Laparoscopic-assisted versus open surgery for colorectal cancer: postoperative morbidity in a single center randomized trial].

AIM: The primary objective of the study was to compare the effect of laparoscopic-assisted (LPS) versus open surgery (LPT) for colorectal cancer on postoperative morbidity. The secondary objectives were to evaluate immune response and intestinal wall oxygen perfusion. METHODS: A total of 610 patients with colorectal cancer were randomly assigned to receive colon resection by either LPS (n=306) or LPT (n=304). Four surgical staff members not involved in the study recorded postoperative complications up to 30 days after the operation. Immune response was evaluated by measuring lymphocytic proliferation after challenge with Candida albicans and phytohemoagglutinin before, at 3 and 15 days after the operation. Intestinal wall oxygen perfusion was continuously monitored using a probe. RESULTS: The conversion rate was 4.6% in the LPS group. Morbidity was 18.6% in the LPS group and 34.5% in the LPT group (P<0.0005). Infections developed in 9.1% of LPS-treated patients and in 20.2% of LPT-treated patients (P<0.0005). The mean length of stay was 9.7+/-2.6 days in the LPS group and 12.2+/-4.2 days in the LPT group (P<0.0001). In both groups lymphocytic proliferation was low at 3 days postoperative but returned to normal range at 15 days only in the LPS group. Interoperative intestinal oxygen perfusion values were higher in the LPS group. CONCLUSIONS: Laparoscopic colorectal surgery reduced both postoperative morbidity and length of stay. Lymphocytic proliferation and intestinal wall oxygen perfusion were higher in patients who underwent laparoscopic-assisted surgery.

Training period in laparoscopic colorectal surgery.

BACKGROUND: Thorough training is essential to the success of colorectal laparoscopic surgery (LPS). The aim of this study was to evaluate the results of a 3-month training period in LPS. METHODS: Before beginning the study, the surgical team attended several courses of LPS and spent a long time working at a large animal facility to perfect laparoscopic techniques. Twenty-six consecutive patients underwent LPS in a 3-month training period. Controls (n = 26) who underwent open colorectal surgery (LPT) were selected to match the LPS patients for age, gender, primary disease, type of surgery, comorbidity, and nutritional status. RESULTS: Conversion to open surgery was necessary in one patient (3.8%). The operative time was 1 h longer for LPS than LPT (p < 0.001). The mean number of lymph nodes harvested was 17 in LPS and 18 in LPT (p = 0.76). The first flatus (p < 0.02) and bowel movement (p < 0.002) occurred earlier in the LPS group. The postoperative infection rate was 11.5% for LPS and 19.2% for LPT (p = 0.33). Two anastomotic leaks occurred in each group. The mean postoperative hospital stay was 9.6 days (standard deviation [SD], 2.6) for LPS and 11.0 days (SD, 5.2) for LPT (p = 0.68). Recovery of postoperative physical performance and social life occurred earlier in the LPS than the LPT group (p < 0.001). At 1-year follow-up, no difference was found in terms of cancer recurrence or long-term complications. CONCLUSION: Oncologic results and postoperative morbidity were comparable for LPS and LPT. LPS allows a faster postoperative recovery.

Locally recurrent rectal cancer: predictors and success of salvage surgery.

PURPOSE: After curative surgery for rectal cancer, patients with pelvic recurrence may undergo curative surgical resection. We determined whether salvage surgery in appropriately selected patients could significantly lengthen disease-free survival time and if so what factors predicted this outcome. METHOD: We reviewed the records of all patients treated for rectal cancer at our institution between 1980 and 1993. Of 937 patients who underwent surgery with curative intent after proctectomy or transanal local excision, 81 (8.6 percent) experienced local recurrence. During the same period 36 patients with locally recurrent rectal cancer were referred from other institutions. Logistic regression analysis was used to identify predictors of salvage surgery. The Kaplan-Meier method was used to estimate cancer-specific and disease-free survival times in 43 patients who underwent salvage surgery. The Cox proportional hazard model was used to identify factors associated with these outcomes. RESULTS: Of 117 patients with locally recurrent rectal cancer, 43 (36.7 percent) underwent salvage surgery. Factors associated with higher chance of receiving salvage surgery were female gender, the first operation performed at outside institutions, and transanal local excision as the initial operation. For 43 patients who underwent salvage surgery, five-year cancer-specific and disease-free survival rates were 49.7 and 32.2 percent, respectively. No factors were significantly associated with death caused by cancer. However, a trend for poor prognosis was observed in patients with recurrence diameter >3 cm and tumor fixation Degree 2. CONCLUSION: Salvage surgery for properly selected patients with locally recurrent rectal cancer allows long-term palliation and significantly lengthens disease-free survival.

Altered microperfusion at the rectal stump is predictive for rectal anastomotic leak.

PURPOSE: The aim of this study was to evaluate the reliability of intraoperative laser-Doppler measurements in predicting the occurrence of anastomotic leak in patients with colorectal cancer undergoing stapled straight anastomosis to the rectum. METHODS: A prospective study was undertaken on 55 patients with rectal cancer or distal sigmoid cancer programmed for elective curative surgery. In all patients transmural colonic blood flow was measured by laser-Doppler flowmetry technique before bowel manipulation (baseline measurement) and after vascular ligation and division. Comorbidities at admission, intraoperative events, associated surgical procedures, and clinical outcome were tested for any association with anastomotic leak. RESULTS: Postoperative mortality was 1.8 percent (1/55 patients), and the overall morbidity was 21.3 percent. Anastomotic leak occurred in eight patients (14.5 percent). After colonic division a blood flow reduction at the rectal stump was observed in 42 patients (76.3 percent) as compared with baseline measurement. The mean rectal stump flow reduction was 6.2 percent in patients without anastomotic leak, whereas in patients who developed anastomosis breakdown it was 16 percent (P < 0.001). Mean proximal stump flow reduction was 5.1 percent in the uncomplicated patients, whereas in patients who had an anastomosis breakdown it was 12.9 percent (P < 0.01). A positive linear correlation was found between decrease in blood flow and rate of anastomotic leak. CONCLUSION: Blood flow reduction at the rectal stump is associated with an increased risk of anastomotic leak.

Perioperative immunonutrition in patients undergoing cancer surgery: results of a randomized double-blind phase 3 trial.

HYPOTHESIS: Perioperative administration of a supplemented enteral formula may reduce the rate of postoperative infections. DESIGN: Prospective, randomized, double-blind clinical trial. SETTING: Department of surgery at a university hospital. PATIENTS: Two hundred six patients with neoplasm of colorectum, stomach, or pancreas. INTERVENTION: Patients were randomized to drink 1 L/d of either a control enteral formula (n = 104) or the same formula enriched with arginine, RNA, and omega3 fatty acids (n = 102) for 7 consecutive days before surgery. The 2 diets were isoenergetic and isonitrogenous. Jejunal infusion with the same formulas was started 6 hours after operation and continued until postoperative day 7. MAIN OUTCOME MEASURES: Rate of postoperative infectious complications and length of hospital stay. RESULTS: Both groups were comparable for age, sex, weight loss, Karnofsky scale score, nutritional status, hemoglobin level, duration of surgery, blood loss, and rate of homologous transfusion. Intent-to-treat analysis showed a 14% (14/102) infectious complication rate in the supplemented group vs 30% (31/104) in the control group (P = .009). In the eligible population, the postoperative infection rate was 11% (9/85) in the supplemented group vs. 24% (21/86) in the control group (P = .02). The mean +/- SD length of postoperative stay was 11.1+/-4.4 days in the supplemented group and 12.9+/-4.6 in the control group (P = .01). CONCLUSION: Perioperative administration of a supplemented enteral formula significantly reduced postoperative infections and length of stay in patients undergoing surgery for cancer.

Splenectomy for idiopathic thrombocytopenic purpura: comparison of laparoscopic and conventional surgery.

BACKGROUND: This study aimed to compare the safety, efficacy, and clinical benefits of laparoscopic splenectomy (LS) to open splenectomy (OS) in patients with idiopathic thrombocytopenic purpura (ITP). METHODS: The results from 14 consecutive patients who underwent LS for ITP were reviewed and compared with the results from patients who underwent OS for the same disease. Demographics, concomitant disease on admission, and platelet counts were evaluated, as were details of the surgical procedure, postoperative physiologic status, and hospital stay. RESULTS: Mean operative time was 88.3 min for OS and 146.4 min in LS group (p < 0.05). The conversion rate to open splenectomy was 7.1. Therapeutic response to splenectomy was 92.8% in the LS group and 86.6% in the OS group. Bowel canalization, return to liquid diet, and length of hospital stay were all significantly delayed in the OS group as compared with those who underwent LS (p = 0.01, p = 0.02, p = 0.005, respectively). In the OS group the morbidity rate was 13.3%, whereas in the LS group it was 7.1%. CONCLUSIONS: Laparoscopic splenectomy represents a valid alternative to conventional splenectomy in the treatment of ITP.

Erythropoiesis after therapy with recombinant human erythropoietin: a dose-response study in anemic cancer surgery patients.

BACKGROUND AND OBJECTIVES: Preoperative treatment with 600 U/kg of recombinant human erythropoietin (r-HuEPO) effectively increases erythropoiesis in cancer patients. The aim of this study was to evaluate the erythropoietic response after different doses of r-HuEPO in order to find the minimum effective dose. MATERIALS AND METHODS: Twenty anemic sideropenic patients (hemoglobin </=110 g/l; serum iron <600 microg/l) with cancer of the gastrointestinal tract were randomly allocated to two groups: the first (n = 10) received 400 U/kg of r-Hu EPO divided in 4 doses (100 U/kg each, every 4 days); the second (n = 10) received 200 U/kg of r-HuEPO (50 U/kg each, every 4 days). Both groups were given intravenous iron gluconate (125 mg) every day for 15 days. RESULTS: After treatment, the serum iron level significantly rose in both groups. The production of new red blood cells was 176.3+/-90.8 ml in the 200 U/kg group and 268.4+/-79.4 ml in the 400 U/kg group (p = 0.036). The increase of hemoglobin was significantly higher in the 400 U/kg group (22.3+/-2.0 g/l) than in the 200 U/kg group (14.1+/-2.7 g/l) (p = 0.017). CONCLUSION: The r-HuEPO dose of 400 U/kg appears significantly more effective than the 200 U/kg to stimulate erythropoiesis in anemic sideropenic cancer patients.

Artificial nutrition after major abdominal surgery: impact of route of administration and composition of the diet.

OBJECTIVE: To evaluate the impact of the route of administration of artificial nutrition and the composition of the diet on outcome. DESIGN: Prospective, randomized, clinical trial. SETTING: Department of surgery, university hospital. PATIENTS: One hundred sixty-six consecutive patients undergoing curative surgery for gastric or pancreatic cancer. INTERVENTIONS: At operation, the patients were randomized into three groups to receive: a) a standard enteral formula (control group; n = 55); b) the same enteral formula enriched with arginine, RNA, and omega-3 fatty acids (enriched group; n = 55); and c) total parenteral nutrition (TPN group; n = 56). The three regimens were isocaloric and isonitrogenous. Enteral nutrition was started within 12 hrs following surgery. The infusion rate was progressively increased to reach the nutritional goal (25 kcal/kg/day) on postoperative day 4. MEASUREMENTS AND MAIN RESULTS: Tolerance of enteral feeding, rate and severity of postoperative complications, and length of hospital stay were recorded. Early enteral infusion was well tolerated. Side effects were recorded in 22.7% of the patients, but only 6.3% did not reach the nutritional goal. The enriched group had a lower severity of infection than the parenteral group (4.0 vs. 8.6; p < .05). In subgroups of malnourished (n = 78) and homologous transfused patients (n = 42), the administration of the enriched formula significantly reduced both severity of infection and length of stay compared with the parenteral group (p < .05). Moreover, in transfused patients, the rate of septic complications was 20.0% in the enriched group, 38.4% in the control group, and 42.8% in the TPN group. CONCLUSIONS: Early enteral feeding is a suitable alternative to TPN after major abdominal surgery. The use of the enriched diet appears to be more beneficial in malnourished and transfused patients.

Effect of route of delivery and formulation of postoperative nutritional support in patients undergoing major operations for malignant neoplasms.

OBJECTIVE: To study the effect of the route of delivery and formulation of postoperative nutritional support on host defense, protein metabolism, infectious complications, and outcome. DESIGN: Prospective, randomized, clinical trial. SETTING: Department of Surgery at a university hospital. PATIENTS: Two hundred sixty candidates for pancreaticoduodenectomy or gastrectomy for cancer. INTERVENTIONS: Patients were randomly allocated into 3 groups during surgery. Starting 6 hours after operation, the first group received a standard enteral formula (standard group; n = 87); the second, the same enteral formula enriched with arginine, omega-3 fatty acids, and RNA (immunonutrition group; n = 87); and the third, total parenteral nutrition (parenteral group; n = 86). The 3 regimens were isocaloric and isonitrogenous. The nutritional goal was 105 kJ/kg per day. MAIN OUTCOME MEASURES: Immune response by phagocytosis ability of polymorphonuclear cells, interleukin (IL)-2 receptor levels, and delayed hypersensitivity response; protein synthesis by IL-6 and prealbumin; tolerance of enteral feeding; incidence of postoperative complications; and length of hospital stay. RESULTS: The immunonutrition group had a significantly better recovery of the immune parameters on postoperative day 8 compared with the other groups. Linear regression analysis showed an inverse correlation between IL-6 and preambulin levels (r = 0.766) only in the immunonutrition group. Only 11 patients (6.3%) in both enteral groups did not reach the nutritional goal. Postoperative infection rate was 14.9% (13/87) in the immunonutrition group, 22.9% (20/87) in the standard group, and 27.9% (24/86) in the parenteral group (P = .06). Mean +/- SD length of hospital stay was 16.1 +/- 6.2, 19.2 +/- 7.9, and 21.6 +/- 8.9 days in the immunonutrition, standard, and parenteral groups, respectively (P = .01 vs standard group; P = .004 vs parenteral group). CONCLUSIONS: Early postoperative enteral feeding is a valid alternative to parenteral feeding in patients undergoing major surgery. Immunonutrition enhances the host response, induces a switch from acute-phase to constitutive proteins, and improves outcome.

Radical oncologic surgery affects the circulatory levels of interleukin 10.

BACKGROUND AND OBJECTIVE: Interleukin 10 (IL-10) has been shown to be elevated in the plasma of cancer-bearing patients. The source of systemic IL-10 may be the tumor microenvironment. We therefore tried to evaluate if ablative surgery for gastrointestinal cancer could affect the levels of circulating IL-10. METHODS: Plasma IL-10 concentration was measured in 45 patients with adenocarcinoma of the gastrointestinal tract. Forty healthy subjects, 15 women undergoing hysterectomy for uterine fibroma, and 15 patients undergoing palliative operation for pancreatic cancer were used as control groups. Plasma IL-10 was assessed 1 day before surgery (baseline) and 1, 4, and 8 days after operation. RESULTS: The baseline concentration of IL-10 was significantly higher in cancer patients than in healthy subjects and in women with fibroma (8.6 ng/mL, 2.1 and 1.8 respectively; P = 0.015). After radical surgery, the IL-10 levels significantly dropped in cancer patients (from 8.6 ng/mL to 3.8; P = 0.024), whereas in subjects undergoing palliative operation, the concentration remained elevated (8.5 ng/mL baseline versus 7.9 on day + 1). CONCLUSIONS: The origin of circulating IL-10 may be the tumor microenvironment.

Modified neck dissection in the treatment of differentiated thyroid carcinoma.

The prognosis of differentiated carcinoma of the thyroid has been reported to be extremely favourable. Previous studies have concluded that lymph node metastasis do not affect survival rates in patients with differentiated thyroid carcinoma. Therefore, nodal metastasis has not been evaluated as a prognostic factor in recent definitions of risk groups. To determine the significance of nodal disease, we reviewed 219 consecutive patients with differentiated thyroid cancer (191 papillary, 14 follicular and 14 Hurtle cell carcinomas). Fifty-five patients were treated with modified neck dissection and all of them received adjuvant radioiodine. There were recurrences in 25 patients (11.4%), with follow-up ranging from 6 months to 14 years. Systemic disease occurred synchronously in two patients, and four patients died of thyroid carcinoma.

Factors associated with the occurrence of leaks in stapled rectal anastomoses: a review of 1,014 patients.

BACKGROUND: Despite improvement in surgical techniques and stapling devices during the last 10 years, colorectal anastomoses are still prone to leakage. The purpose of this study was to assess the performance and safety of stapled anastomoses in rectal surgery and to identify factors that influence the occurrence of anastomotic leaks. STUDY DESIGN: A review was undertaken of 1,014 patients who underwent stapled anastomoses to the rectum or anal canal for colorectal cancer or benign disease between 1989 and 1995 in a tertiary care institution. Indications for operations, comorbidities at admission, preoperative bowel preparation, stapler size, intraoperative events, associated surgical procedures, and clinical outcomes were tested for any association with anastomotic leak. RESULTS: A double stapled technique was used in 154 patients and a conventional single stapler technique was used in 860. Postoperative mortality was 1.6%, and the overall morbidity was 18.4%. Clinically apparent anastomotic leak developed in 29 patients (2.9%). Anastomotic dehiscence occurred in 22 of 284 patients (7.7%) after low stapling (within 7 cm from the anal verge) and in 7 of 730 patients (1%) after high stapling (p < 0.001). Diabetes mellitus, use of pelvic drainage, and duration of surgery were significantly related to the occurrence of anastomotic leak by the univariate analysis. Multivariate regression analysis identified an anastomotic distance from the anal verge within 7 cm as the only variable related to the occurrence of postoperative leak (p < 0.001). CONCLUSION: Low anastomoses were associated with a leak rate greater than with high colorectal anastomoses. We conclude that anastomoses to the rectum using the circular stapler can be done with low mortality and morbidity.

Gut function and immune and inflammatory responses in patients perioperatively fed with supplemented enteral formulas.

OBJECTIVE: To evaluate if the perioperative administration of a supplemented enteral formula modulates selective inflammatory and immune variables and gut function after surgery. DESIGN: Prospective, randomized, double-blind, clinical trial. SETTING: Department of surgery, university hospital. PATIENTS: Forty patients with neoplasm of the colorectum or stomach. INTERVENTION: Seven days before surgery, the patients drank 1 L/d of a control enteral formula (n = 20) or the same formula enriched with arginine, RNA, and omega-3 fatty acids (n = 20). Jejunal infusion with the same formulas was started 6 hours after operation and continued until day 7. MAIN OUTCOME MEASURES: Immune response was determined by phagocytosis ability and respiratory burst of polymorphonuclear cells, and inflammatory response by plasma levels of C-reactive protein. Operative intestinal microperfusion, postoperative intestinal mucosa oxygen metabolism, and plasma intestinal isoenzyme of alkaline phosphatase were used as indicators of gut function. Plasma nitric oxide also was determined. RESULTS: In the enriched group, phagocytosis ability and respiratory burst after surgery was higher (P < .01) and C-reactive protein level was lower (P < .05) than in the control group. The enriched group had higher mean (+/-SD) intestinal microperfusion (180 +/- 46 vs 146 +/- 59 perfusion units, P < .05), intestinal mucosa oxygen metabolism (pHi 7.39 +/- 0.2 vs pHi 7.33 +/- 0.1, P < .05), and 5-fold lower levels of intestinal isoenzyme of alkaline phosphatase (P < .05). Postoperative levels of nitric oxide were higher in the enriched group (P < .05, analysis of variance). CONCLUSION: The perioperative administration of an enriched enteral formula significantly improved gut function and positively modulated postsurgical immunosuppressive and inflammatory responses.

A single unit of transfused allogeneic blood increases postoperative infections.

The aim of this prospective study was to evaluate if there was a statistical correlation between allogeneic blood transfusion and postoperative infections, and if this could have a dose-dependent pattern. The evaluation was based on multiple logistic and receiver operating characteristics (ROC) curve analyses. On hospital admission the following parameters were determined in 267 consecutive patients with colorectal cancer: hemoglobin, serum albumin, serum cholinesterase activity, total iron binding capacity and weight loss. Duration of operation, operative blood loss, amount of transfused blood, Dukes' cancer stage and occurrence of postoperative infections were also recorded. One hundred and thirty-two patients (49.4%) were given perioperatively allogeneic blood. Postoperative infections developed in 47 (17.6%) patients. Multivariate analysis identified allogeneic blood transfusion as the only variable related to the occurrence of postoperative infections (p < 0.05). ROC curve analysis showed that the risk for the occurrence of infection was significantly higher in patients transfused one unit of blood (p < 0.01). Moreover, a significant trend between increasing number of transfused blood units and susceptibility to infection was found (p < 0.00019).

Immune and nutritional effects of early enteral nutrition after major abdominal operations.

AIM: To investigate the effect of early postoperative enteral nutrition enriched with arginine, RNA and omega-3 fatty acids on immunological and nutritional variables after elective curative operations for gastric or pancreatic cancer. DESIGN: Randomised controlled trial. SETTING: University hospital, Italy. SUBJECTS: 78 Consecutive patients who were to undergo curative operations for gastric or pancreatic cancer, 60 of whom were suitable for the study. INTERVENTIONS: Patients were randomly allocated to three groups (n = 20 each) according to the type of postoperative nutritional support: standard enteral diet, the same diet enriched with arginine, RNA, and omega-3 fatty acids or total parenteral nutrition. The daily nutritional goal was 25 kcal (105 kJ)/kg and 0.25 g nitrogen/kg for all patients. MAIN OUTCOME MEASURES: Serum concentrations of immunoglobulins, albumin, transferrin, prealbumin, retinol binding protein (RBP); cholinesterase activity, weight loss, duration of operation, operative blood loss; blood transfusion; delayed hypersensitivity responses, number of lymphocyte subsets, phagocytic ability of monocytes, number of interleukin-2 (IL-2) plasma receptors, interleukin-6 (IL-6) plasma concentrations, postoperative infections and sepsis scores. RESULTS: All enterally fed patients but one completed the nutritional programme. There were significant postoperative reductions in both nutritional and immunological variables in all groups. On postoperative days 4 and 8 prealbumin concentration (p < 0.05), RBP concentration (p < 0.05), delayed hypersensitivity responses (p < 0.05), phagocytic ability of monocytes (p < 0.01) and concentration of IL-2 receptors (p < 0.009) had all recovered more in the group receiving the enriched solution. There was no difference in the postoperative infection rates among the three groups, but the infections were less severe in the enriched group (p < 0.005). CONCLUSION: Early enteral feeding was well tolerated. Patients who received the enriched solution recovered both their nutritional and immunological status quicker than those in the other two groups.

Evaluation of recombinant human erythropoietin to facilitate autologous blood donation before surgery in anaemic patients with cancer of the gastrointestinal tract.

The aim of this study was to determine whether the preoperative administration of recombinant human erythropoietin (rHuEPO) could increase the rate of autologous blood donation and reduce the perioperative need for homologous blood in anaemic patients with cancer. Twenty-two anaemic (haematocrit less than 34 per cent), iron-deficient (iron less than 700 micrograms/l) patients, with gastric or colorectal cancer scheduled for elective surgery, were allocated randomly to two groups. The first (n = 11) received iron saccharate 200 mg/day intravenously for 12 consecutive days. The second (n = 11) received rHuEPO subcutaneously (300 units/kg as first administration, and 100 units/kg 4, 8 and 12 days later) with supplemental iron. On days 4, 8 and 12, if the haematocrit was greater than 34 per cent, patients donated one unit (350 ml) of autologous blood. In the iron group the mean haematocrit did not change from admission (31 per cent) to day 12 of treatment (31 per cent), and no patient could donate autologous blood. In the rHuEPO group, eight patients donated two units of autologous blood and three donated one unit. Four patients in the iron group received perioperative transfusion of homologous blood compared with none in the rHuEPO group. Administration of rHuEPO facilitated the donation of autologous blood and reduced perioperative homologous blood transfusion in anaemic patients with cancer.
