What are cancer patients willing to pay for prophylactic epoetin alfa? A cost-benefit analysis

BACKGROUND: Anemia, one of the most common complications of cancer chemotherapy, has been managed with red blood cell (RBC) transfusions. As an alternative, the agent epoetin alfa has the potential to reduce the transfusion requirements of patients receiving cancer chemotherapy. To estimate the value that cancer patients place on the drug, an economic analysis using the concept of willingness to pay (WTP) was conducted. METHODS: The method of WTP was used within the framework of a classical cost-benefit analysis to estimate the net cost or benefit of administering prophylactic epoetin alfa to cancer patients. This estimate included the direct cost of epoetin alfa administration and savings secondary to reduced RBC transfusions. A cohort of 100 cancer patients who received or were scheduled to receive cisplatin or noncisplatin chemotherapy (50 per group) were then interviewed to measure the maximum WTP (net benefit) that they experienced with epoetin alfa. RESULTS: Regarding the benefits they would experience after 3 months of epoetin alfa administration, patients receiving cisplatin and noncisplatin therapy stated that they would be willing to pay an average of 587 U.S. dollars (U.S.$587) (95%CI: $300-$875) and U.S.$613 (95%CI: $324-$902), respectively. These benefits were then subtracted from the total cost of the drug when administered to patients receiving cisplatin (U.S.$3530) and noncisplatin (U.S.$3653) therapy. This produced a net incremental treatment cost of U.S.$2943 (95%CI: $2655-$3230) and U.S.$3039 (95%CI: $2750-$3328) for the respective treatment groups. CONCLUSIONS: The results of the current study suggest that the routine administration of epoetin alfa to cancer patients receiving myelosuppressive chemotherapy is a highly resource-intensive treatment policy with modest benefit to patients. Additional research is required to identify high risk patient subgroups who would benefit most from the drug. [See editorial on pages 2427-9, this issue.]     

The effect of subcutaneous recombinant human erythropoietin (r-HuEPO) on anemia in cancer patients receiving platinum-based chemotherapy

Advanced cancer is commonly associated with significant anemia which worsens with the administration of cytotoxic drugs. Erythropoietin (EPO) levels in these patients are usually inappropriately low for the degree of anemia. We evaluated the effect of subcutaneous administration of recombinant human erythropoietin (r-HuEPO) on hematologic parameters and transfusion requirements in anemic cancer patients who were receiving platinum-based chemotherapy. Baseline studies included complete hemogram, reticulocyte count, serum iron, TIBC, ferritin and determination of performance status and quality of life (QOL). Twenty-three patients, 13 females, 10 males with mean age 52 years received 150 units/kg of r-HuEPO three times weekly for a minimum of 10 weeks. They also received supplemental iron. Ovarian cancer was the commonest underlying malignancy. Most of the patients received platinum-based combination chemotherapy. Mean duration of r-HuEPO therapy was 12.6 weeks. Average baseline reticulocyte count was 1.8% which increased to 7.0% after one week therapy. Eight patients had normalization of hemoglobin values. Another eight patients improved their hemoglobin by at least 2 g/dl, however, hemoglobin values remained below the normal range. Two patients had only slight increase in hemoglobin but never required blood transfusion. Three patients who were transfusion dependent had decrease in the transfusion requirements. Two patients had no significant benefit. In most patients response was evident within 2 weeks. All responders had improvement in QOL. No significant toxicity was observed. We conclude that r-HuEPO, given subcutaneously, is highly effective in amelioration of anemia and prevention of or reduction in transfusion requirements in cancer patients receiving platinum-based chemotherapy.     

Preoperative recombinant human erythropoietin injection versus preoperative autologous blood donation in patients undergoing radical retropubic prostatectomy

OBJECTIVES: In an effort to avoid allogeneic transfusions, many patients scheduled for radical retropubic prostatectomy (RRP) participate in preoperative autologous donation (PAD) programs. Yet, PAD programs are costly, time-consuming, and not without risks. Perioperative administration of recombinant human erythropoietin (Epoetin alfa) also has been shown to reduce patients exposure to allogeneic transfusion. This study sought to compare the costs and transfusion rates associated with either PAD or perioperative Epoetin alfa in patients undergoing RRP. METHODS: The study population consisted of 120 men randomized to one of two treatment groups. Patients in group 1 donated up to 3 U of autologous blood preoperatively, provided that their hematocrit (HCT) was 33% or higher. Patients in group 2 received 600 IU/kg of Epoetin alfa on days -14 and -7 preoperatively, provided that their HCT was 46% or lower. RESULTS: Overall, 107 (89%) of 120 patients underwent RRP. In group 1, 5 (9.6%) of 52 patients received a total of 12 U of allogeneic blood (0.23 U/patient). In group 2, 5 (9.6%) of 52 patients received a total of 10 U of allogeneic blood (0.19 U/patient). Three patients in group 1 but no patients in group 2 experienced an adverse event. The average costs related to PAD and pharmacologic administration per patient were $540 in group 1 and $657 in group 2. Participation in PAD required an average of 5 hours more per patient compared with Epoetin alfa administration. CONCLUSIONS: Preoperative Epoetin alfa therapy is safe, well tolerated, and equally effective as PAD in reducing allogeneic blood transfusion requirements. Epoetin alfa therapy also is comparable in cost to PAD and offers patients greater convenience and less of a time commitment.     

CD34+CD33- cells influence days to engraftment and transfusion requirements in autologous blood stem-cell recipients

PURPOSE: To evaluate the reliability of CD34/CD33 subset enumeration as a predictor of hematopoietic repopulating potential in autologous blood stem-cell transplantation and to determine which patient and treatment-related factors affect the timing, quantity, and type of blood stem cells mobilized. PATIENTS AND METHODS: We analyzed blood stem-cell collections from 410 consecutive cancer patients who received mobilization therapy and evaluated factors, including CD34+ subset quantities, that might influence engraftment kinetics and transfusion requirements in autologous blood stem-cell recipients. RESULTS: The majority of patients (97%) mobilized CD34+33- cells, which were usually collected in the greatest quantity on the first day of apheresis. Patients who received only growth factor mobilized the highest percentage of CD34+33- cells. Extensive prior chemotherapy limited the collection of CD34+33- cells. In addition to patient diagnosis (P < .006) and total CD34+ cell dose (P = .0001), CD34+33- cell dose (P < .005) and percentage of CD34+33- cells (P < .005) were identified as independent factors significantly predictive of engraftment kinetics. CD34+33- cell dose (R2 < or = .177; P < .0001) was a strong and the only significant predictor of RBC and platelet transfusion requirements. Furthermore, independent of the total CD34+ cell dose, as the CD34+33- cell dose increased, days to neutrophil recovery, days to platelet recovery, and transfusion requirements decreased. CONCLUSION: These findings show that CD34+33- cells are readily collected in most cancer patients and significantly influence engraftment kinetics and transfusion requirements in autologous blood stem-cell recipients. CD34+33- cell quantity of the blood stem-cell graft appears to be a more reliable predictor of hematopoietic recovery rates than total CD34+ cell quantity in this setting.     

Structural thermodynamics: prediction of protein stability and protein binding affinities

It has been demonstrated that the prognosis of ovarian cancer is influenced by the dose intensity of cytotoxic treatment. The impact of received dose intensity of platinum-based combination chemotherapy on disease outcome was analysed in 226 stage III-IV ovarian cancer patients entered into two prospective randomised trials. All patients received either cisplatin or carboplatin and cyclophosphamide with or without doxorubicin for six courses after primary surgery. The impact of the received dose intensity of each drug (RDI), the average received dose intensity of the treatment regimen (ARDI) and the relative total drug dose (RTD) on progression-free survival (PFS) and survival were analysed. In the 198 patients receiving the full six courses of treatment, RDI of cisplatin or carboplatin, ARDI and RTD were > 0.76 in 74.2, 61.1 and 65.1% of cases, respectively. Although the differences were not significant, pathological complete response was more frequently observed in the group of patients with ARDI < 0.75, whereas the partial response rate was higher in the ARDI > or = 0.76 group. Median survival and PFS were 19 and 13 months; 22 and 10 months; 23 and 13 months for the groups of patients receiving chemotherapy at a ARDI of < 0.75, > or = 0.76-0.99 and > 1.00, respectively (P = not significant). It appears that modest dose modifications and brief treatment delays during first-line platinum-based chemotherapy do not affect response rate, survival and PFS in advanced ovarian cancer patients.     

Clinical and in vitro effects of recombinant human erythropoietin in patients receiving intensive chemotherapy for small-cell lung cancer

PURPOSE: Recombinant human erythropoietin (r-Hu-EPO) is known to be effective in untreated cancer patients. Here we assess the possibility that r-Hu-EPO may also prevent or reduce anemia in patients who receive cytotoxic chemotherapy. METHODS: Thirty-six patients with small-cell lung carcinoma (SCLC) were enrolled onto a three-arm, randomized trial to investigate the effect of r-Hu-EPO on hemoglobin (Hb) levels and RBC and platelet (Plt) transfusions during chemotherapy. Bone marrow progenitors were studied before and after treatment. Two groups of patients received r-Hu-EPO at a dose of either 150 IU/kg (group 150) or 300 IU/kg (group 300) three times per week for the duration of chemotherapy. A control group did not receive r-Hu-EPO (group O). A maximum of six cycles of a chemotherapy regimen that consisted of vincristine, ifosfamide, carboplatin, and etoposide (VICE) were given to all patients. Hematologic parameters were measured weekly, and RBC or Plt transfusions were given for Hb levels less than 9 g/dL and Plt counts less than 20 x 10(9)/L. RESULTS: Hb levels decreased in all patients, but onset of anemia was delayed in groups that received r-Hu-EPO (P = .002). A total of 116 U RBC were transfused in group 0, 54 in group 150, and 52 in group 300 (P = .017). In addition, there was a nonsignificant trend toward higher Plt counts and fewer Plt transfusions in patients who received r-Hu-EPO. CONCLUSION: r-Hu-EPO at a dose of either 150 or 300 IU/kg three times weekly delays the onset of anemia and reduces RBC transfusion requirements in patients who undergo intensive chemotherapy for SCLC. A possible effect of r-Hu-EPO on platelet numbers deserves further study.     

Five-year followup of a prospective trial of radical cystectomy and neoadjuvant chemotherapy: Nordic Cystectomy Trial I. The Nordic Cooperative Bladder Cancer Study Group

PURPOSE: Chemotherapy is widely used in patients with locally advanced bladder cancer but until now there has been no conclusive evidence that this therapy improves survival. The Nordic Cooperative Bladder Cancer Study Group conducted a randomized phase III study to assess the possible benefit of neoadjuvant chemotherapy in patients with bladder cancer undergoing radical cystectomy after short-term radiotherapy. MATERIALS AND METHODS: Our trial included 325 patients with locally advanced stage T1 grade 3 or stages T2 to T4aNXM0 bladder cancer allocated randomly into a chemotherapy or no chemotherapy group (control). The chemotherapy schedule consisted of 2 cycles of 70 mg./m.2 cisplatin and 30 mg./m.2 doxorubicin with a 3-week interval between the cycles. RESULTS: After 5 years the overall survival rate was 59% in the chemotherapy group and 51% in the control group (p = 0.1). The corresponding cancer specific survival rate was 64 and 54%, respectively. In regard to treatment, no difference was observed for stages T1 and T2 disease, while there was a 15% difference in overall survival for patients with stages T3 to T4a disease (p = 0.03). In a multivariate analysis only chemotherapy and T category emerged as independent prognostic factors. The relative death risk for patients who received chemotherapy was 0.69 (95% confidence interval 0.49 to 0.98) compared to the control group after adjustment for the other tested factors. CONCLUSIONS: Neoadjuvant chemotherapy seems to improve long-term survival after cystectomy in patients with stages T3 to T4a bladder carcinoma, while no survival benefit was found for stages T1 to T2 disease.     

Autologous platelet-rich plasmapheresis: risk versus benefit in repeat cardiac operations

Preoperative platelet-rich plasmapheresis has been suggested as a means of reducing homologous blood transfusions in cardiac surgical patients. The current study evaluated this technique in patients undergoing repeat cardiac operations. Fifty-two patients undergoing repeat myocardial revascularization and/or valve replacement were evaluated in a prospective randomized controlled study design. Autologous platelet-rich plasma (PRP) was harvested after the induction of anesthesia in the experimental group. After reversal of heparin, each patient received his or her autologous plasma. Patients in the control group did not have plasmapheresis and received standard transfusion therapy if coagulation variables were abnormal and a coagulopathy was clinically evident. Routine coagulation tests, thromboelastography (TEG), perioperative bleeding, and transfusion requirements were compared in the two groups. Forty-four patients completed the study. A significantly larger volume of packed red blood cells (PRBCs) was transfused in the PRP group than in the control group (P = 0.03). Platelet and fresh frozen plasma (FFP) transfusions did not differ between the two groups. Mediastinal tube drainage did not differ between the two groups. During PRP infusion, 60% of the patients required treatment for moderate hypotension (mean arterial pressure [MAP] < 60 mm Hg). Only 16% of control patients required treatment for hypotension during the comparable time period (P < 0.05). No patient who completed the study returned to the operating room for postoperative bleeding. These data suggest that PRP did not reduce postbypass bleeding or transfusion requirements in repeat cardiac surgical patients. Moreover, the incidence of hypotension during PRP reinfusion introduces a potential risk to the procedure in the absence of any obvious benefit.     

Cost of managing anemia with and without prophylactic epoetin alfa therapy in breast cancer patients receiving combination chemotherapy

The cost of managing anemia with prophylactic epoetin alfa therapy versus blood transfusions in breast cancer patients receiving combination chemotherapy was studied. A retrospective study of anemia in breast cancer patients treated with four cycles of cyclophosphamide and doxorubicin with fluorouracil (CAF) or without fluorouracil (CA) was conducted. For each cycle of chemotherapy, patients were assessed for fatigue, subsequent blood transfusions administered, and potential response to and adverse effects of blood transfusions. Transfusions were given at the prescriber's discretion rather than in accordance with standard guidelines. The lowest hemoglobin concentration and hematocrit of each patient per cycle were reported. Data on these patients, along with data from published studies of prophylactic use of epoetin alfa, were used in a decision analysis of the costs associated with using epoetin alfa versus red blood cell transfusions to manage anemia. The charts of 50 patients were reviewed. In the study group, the percentage of patients with anemia and the frequency of fatigue rose with each chemotherapy cycle. In general, blood transfusions were not used. The cost of using epoetin alfa prophylactically for all four cycles was estimated at $6483 per patient for the literature-based group versus $169 for the study group. The cost of managing anemia in breast cancer patients was substantially lower when blood transfusions were used than when epoetin alfa was given prophylactically throughout four cycles of therapy with CAF or CA; the absence of standard guidelines for transfusion might have exaggerated the difference in costs.     

Modeling the cost-effectiveness of granulocyte colony-stimulating factor use in early-stage breast cancer

PURPOSE: To model the cost-effectiveness (CE) of granulocyte colony-stimulating factor (G-CSF) in early-stage breast cancer when its use is directed to those most in need of the medication. METHODS: A conditional CE model was developed for the use of G-CSF based on a ranking of patient need as determined by patient blood counts during the first cycle of chemotherapy. In the base case, no G-CSF was used. In the alternative case, G-CSF was used in the following manner. If the risk of a neutropenic event (as defined by a predictive model based on nadir absolute neutrophil count [ANC] and hemoglobin decrease in cycle 1) was equal to or exceeded a predetermined critical value "T," then patients would receive G-CSF in cycles 2 through 6 of chemotherapy. If the risk of an event was less than T, patients would not use G-CSF unless an event occurred, at which time G-CSF would be administered with every subsequent cycle. RESULTS: A decision rule (T) that would allow the most needy 50% of early-stage breast cancer patients to receive G-CSF after the first cycle of chemotherapy resulted in a CE ratio of $34,297 dollars per life-year saved (LYS). If only the most needy 10% of patients received G-CSF, then the associated CE ratio was $23,748/LYS; if 90% of patients could receive the medication, the CE ratio would be $76,487/LYS. These estimates were relatively insensitive to inpatient hospital cost estimates (inpatient costs for fever and neutropenia of $3,090 to $7,726 per admission produced dollar per LYS figures of $34,297 to $32,415, respectively). However, the model was sensitive to assumptions about the shape of the relationship between dose reduction and disease-free survival (DFS) at 3 years. CONCLUSION: Providing G-CSF to the neediest 50% of early-stage breast cancer patients (as defined by first-cycle blood counts) starting after the first cycle of chemotherapy is associated with a CE ratio of $34,297/LYS, which is well in the range of CE ratios for treatment of other common medical conditions. Furthermore, conditional CE studies, based on predictive models that incorporate individual patient risk, allow one to define populations for which therapy is, or is not, cost-effective. Limitations of our present understanding of the shape of the chemotherapy dose-response curve, especially at low levels of dose reductions, affect these results. Further work is required to define the shape of the dose-response curve in early-stage breast cancer.     

Frequency, predictors, and appropriateness of blood transfusion after percutaneous coronary interventions

Increased awareness of the risks of blood-borne infections has recently led to profound changes in the practice of transfusion medicine. These changes include, among others, the development of guidelines by the American College of Physicians (ACP) for transfusion. Although the incidence and predictors of vascular complications of percutaneous interventions have been well defined, there are currently no data on frequency, risk factors, and appropriateness of blood transfusions. We performed a retrospective analysis of 628 consecutive percutaneous coronary revascularization procedures. Predictors of blood transfusion were identified using multivariate logistic regression analysis. Appropriateness of transfusions was determined using modified ACP guidelines. Transfusions were administered after 8.9% of interventions (56 of 628). Multivariate analysis identified age >70 years, female gender, procedure duration, coronary stenting, acute myocardial infarction, postprocedural use of heparin and intra-aortic balloon pump placement as independent predictors of blood transfusions (all p <0.05). According to the ACP guidelines, 36 of 56 patients (64%) received transfusions inappropriately. Transfusion reactions (fever) occurred in 10% of patients who received tranfusions appropriately and in 5% of patients who received tranfusions inappropriately. The estimated additional costs per procedure related to transfusions were $551 and $419, respectively. In conclusion, unnecessary transfusions were performed frequently after percutaneous coronary interventions. Application of available guidelines could reduce the number of unnecessary transfusions, thus avoiding exposure of patients to additional risks and reducing procedural costs.     

Nitrofurantoin prophylaxis for bacteriuria and urinary tract infection in children with neurogenic bladder on intermittent catheterization

OBJECT: This study was undertaken to determine the efficacy of preoperative erythropoietin administration in infants scheduled for craniofacial surgery and, in so doing, to minimize problems associated with blood transfusions. METHODS: Families were offered the option of having their children receive erythropoietin injections before undergoing craniofacial surgery. The children whose families accepted this option received daily iron and 300 U/kg erythropoietin three times per week for 3 weeks preoperatively. Weekly complete blood counts with reticulocyte counts were measured and transfusion requirements were noted. Blood transfusions were administered depending on the clinical condition of the child. A case-matched control population was also evaluated to compare initial hematocrit levels and transfusion requirements. Thirty patients in the erythropoietin treatment group and 30 control patients were evaluated. The dose of erythropoietin administered was shown to increase hematocrit levels from 35.4 +/- 0.9% to 43.3 +/- 0.9% during the course of therapy. The resulting hematocrit levels in patients treated with erythropoietin at the time of surgery were higher compared with baseline hematocrit levels obtained in control patients at the time of surgery (34.2 +/- 0.5%). Transfusion requirements also differed: all control patients received transfusions, whereas 64% (19 of 30) of erythropoietin-treated patients received transfusions. CONCLUSIONS: The authors conclude that treatment with erythropoietin in otherwise healthy young children will increase hematocrit levels and modify transfusion requirements. Erythropoietin therapy for elective surgery in children of this age must be individualized according to the clinical situation, family and physician beliefs, and cost effectiveness, as evaluated at the individual center.     

Transfusion management in pediatric and adolescent scoliosis surgery. Efficacy of autologous blood

STUDY DESIGN: A retrospective review of consecutive pediatric and adolescent patients who required posterior spinal fusion to correct scoliosis. OBJECTIVES: To 1) measure the participation of pediatric patients in predeposit programs for autologous and directed blood donation 2) to assess the success of autologous predonation in preventing allogeneic blood use, 3) to determine whether transfusion indications differed between patients who received allogeneic blood and those who received autologous blood, and 4) to assess factors that predict transfusion requirements during scoliosis surgery. SUMMARY OF BACKGROUND DATA: Authors of recent studies in adults have questioned whether transfusion of autologous blood is a cost-effective therapy when compared with the less-expensive alternative--transfusion of allogeneic blood. In children, the efficacy of autologous blood has not been assessed in a large population of surgical patients. In adults, the frequency of patient participation, the success of autologous donors in avoiding allogeneic transfusion, and the proportion of collected autologous units used during the perioperative period are measures used to establish the efficacy of autologous predonation programs. METHODS: Hospital and clinic records for each patient who underwent posterior spinal fusion from September 1, 1989 through September 1, 1994 were reviewed. Blood bank consultation, autologous donation records, anesthesia records, surgical reports, and hospital records were reviewed. Seventy percent of patients (164 of 243) participated in autologous donation. RESULTS: More than 90% of autologous donors successfully avoided receiving allogeneic blood. Patients with idiopathic scoliosis (n = 168) were more likely to participate in autologous donation (n = 144) and to avoid allogeneic blood (n = 135). Patients with neurologic causes of scoliosis more commonly used allogeneic or directed donation (56 of 75 patients). Nineteen patients with neuromuscular causes of scoliosis participated in autologous donation, but more than one half of this group (10 of 19 patients) required allogeneic blood in addition to autologous units. CONCLUSIONS: Using measures of efficacy similar to those reported in studies of adults, autologous blood was found to be more effective in meeting the transfusion needs of pediatric patients who required posterior spinal fusion than in meeting those needs in adult surgical patients in previous studies.     

Frontal sinus mucoceles causing proptosis--two case reports

BACKGROUND: Blood requirements for Head and Neck surgical procedures have not been studied carefully. In order to set up an autotransfusion program, the blood loss and transfusion requirements should be known precisely. METHODS: The blood bank database was used to determine which Head and Neck procedures required blood transfusion during the previous 5 years. A list of 10 transfusion-associated operations was established, the records of all patients who underwent these procedures during a 5-year period were reviewed, and average the blood loss and number of units transfused determined. RESULTS: All procedures were for cancer resection. The operations were classified in 3 groups according to their transfusion probability: high (> 80%), low (< 5%) and moderate. For the moderate transfusion group, age, preoperative hemoglobin, and past medical history of cardiac and pulmonary disease were associated with higher incidence of transfusion. An average delay of 3 weeks was found between the diagnosis and the actual surgery. CONCLUSION: The transfusion requirements of Head and Neck surgical procedures could be safely met by an autotransfusion protocol, given the average delay of 3 weeks between diagnosis and surgery.     

Recombinant human erythropoietin as adjuvant treatment for autologous blood donation in elective surgery with large blood needs (> or = 5 units): a randomized study

BACKGROUND: Autologous blood transfusion presents no infectious or immunologic side effects. The aim of this randomized study was to determine the impact of recombinant human erythropoietin (rHuEPO) on the donation of 5 units of autologous blood by nonanemic patients who were candidates for elective surgery with transfusion requirements of > or = 5 units. STUDY DESIGN AND METHODS: Starting on Day -35, 420 mL of blood was taken weekly. All patients received 200 mg of iron saccharose complex intravenously at each visit and six subcutaneous injections of rHuEPO (141 U/kg) or placebo between Days -21 and -7. RESULTS: Of 50 patients, 45 completed the study (placebo, 21; rHuEPO, 24). Total red cell production was higher in the rHuEPO group (p = 0.001). Donation of 5 units was possible for 67 percent (placebo group) and 79 percent (rHuEPO group) of patients (p = 0.5). The mean number of blood units donated was 4.6 (placebo group) and 4.7 (rHuEPO group). More patients in the placebo group received allogeneic blood (9/21 [43%] vs. 6/23 [26%]), although the difference did not reach significance (p = 0.34). CONCLUSION: In nonanemic patients donating 5 units of blood, rHuEPO associated with intravenous iron increased total red cell production. However, no difference was found between the rHuEPO and placebo groups with regard to the number of units of autologous blood donated of the number of patients receiving allogeneic blood transfusion.     

Treatments for newly diagnosed advanced ovarian cancer: analysis of survival data and cost-effectiveness evaluation

The main therapeutic options currently available for patients with newly diagnosed advanced ovarian cancer include: (i) cisplatin-based chemotherapy at conventional doses without paclitaxel, (ii) paclitaxel+cisplatin at conventional doses and (iii) high-dose chemotherapy with autologous hematopoietic rescue. After conducting a literature search to identify large-scale clinical trials based on these three therapeutic modalities, we carried out an analysis of the survival data and evaluated the cost-effectiveness ratio where appropriate. Cost data were obtained from published information. Effectiveness was estimated by determining the values of mean lifetime survival (MLS). Our analysis included a total of 15 clinical trials. The values of MLS were 3.05 years per patient for cisplatin-based chemotherapy at conventional doses without paclitaxel (1931 patients), 2.95 years per patient for chemotherapy with paclitaxel+cisplatin at conventional doses (184 patients) and 5.76 years per patient for high-dose chemotherapy with autologous hematopoietic rescue (53 patients). As compared with cisplatin-based chemotherapy without paclitaxel, high-dose treatments with hematopoietic rescue yielded a significantly better survival. Using cisplatin-based chemotherapy as a reference term, the incremental cost-effectiveness ratio for high-dose treatments was $25641 per life year gained (discounted dollars per discounted life year gained). Sensitivity testing suggested that the ratio remained below $50000 under most circumstances. We conclude that in the treatment of patients with advanced ovarian cancer, high-dose chemotherapy with hematopoietic rescue seems to be more effective and more cost-effective than standard treatments with cisplatin-based regimens at conventional doses.     

Effect of blood transfusion on survival after esophagogastrectomy for carcinoma

BACKGROUND: There is growing evidence that blood transfusion is associated with clinical factors that can lead to transfusion-induced immunosuppression. This effect can be beneficial or deleterious. METHODS: The effect of perioperative allogeneic blood transfusion on survival was studied retrospectively in 524 patients who were discharged from the hospital after esophagogastrectomy for carcinoma performed in a single unit over a 10-year period. RESULTS: The median operative blood loss for the series was 500 mL (range, 50 to 3,750 mL). Three hundred thirty-five patients (64%) received a perioperative allogeneic blood transfusion related to esophagogastrectomy, and 189 (36%) did not. The median perioperative blood transfusion administered was 900 mL (range, 300 to 12,950 mL). Perioperative allogeneic blood transfusion was associated with reduced survival for patients in stage III (p < 0.05) at 1 year, but no significant difference was found in this stage at 3 or 5 years after resection. Stage III disease accounted for 250 (48%) of the 524 patients discharged. CONCLUSIONS: Although perioperative allogeneic blood transfusion does not affect long-term survival after esophagogastrectomy for carcinoma, it does have a significant association with short-term survival in a group whose overall survival is often limited after resection. Attention should be directed toward minimizing operative blood loss and transfusing only for factors known to be clinically important, such as oxygen delivery and hemodynamics, not arbitrary hemoglobin levels.     

Paclitaxel in combination chemotherapy with radiotherapy in patients with unresectable stage III non-small-cell lung cancer

PURPOSE: The addition of combination chemotherapy to standard radiation therapy has improved treatment for locally unresectable non-small-cell lung cancer. In this phase II study, we evaluated the toxicity and efficacy of a novel chemotherapy regimen that included paclitaxel, cisplatin, and etoposide plus concurrent radiation therapy in this group of patients. PATIENTS AND METHODS: Thirty-three patients with previously untreated, unresectable stage III non-small-cell lung cancer (stage IIIA, 11 patients; stage IIIB, 22 patients) initially received two courses of chemotherapy, which included paclitaxel 135 mg/m2 by 1-hour infusion on day 1, cisplatin 60 mg/m/ intravenously (i.v.) on day 2, and etoposide 100 mg/m2 i.v. on days 1, 2 and 3. On week 6, radiation therapy (60 Gy in 30 fractions) was initiated in conjunction with two additional courses of chemotherapy: paclitaxel 135 mg/m2 i.v. by 1-hour infusion on day 1, cisplatin 5 mg/m2 i.v. on days 2- to 10, and etoposide 25 mg/m2 on days 1 to 10. RESULTS: This combined modality program was feasible and well tolerated by most patients. During the two courses of induction chemotherapy, grade 3 or 4 myelosuppression occurred in only six patients (18%). Esophagitis was common during combined modality therapy (grade 3, 10 patients; grade 4 five patients). Forty-two percent of patients had partial response after two courses of induction therapy, and 82% of patients had an objective response at completion of therapy. Twelve patients (36%) had a complete response. Nineteen patients remain progression-free at a median of 8 months; the median survival time has not been reached. CONCLUSION: This paclitaxel-containing combined modality therapy is feasible and highly active in patients with inoperable stage III lung cancer. Esophagitis is the most common severe toxicity with this program. Further studies with paclitaxel-containing combination regimens in patients with stage III non-small-cell lung cancer are indicated.     

Chemotherapy followed by surgery compared with surgery alone for localized esophageal cancer

BACKGROUND: We performed a multi-institutional randomized trial comparing preoperative chemotherapy followed by surgery with surgery alone for patients with local and operable esophageal cancer. METHODS: Preoperative chemotherapy for patients randomly assigned to the chemotherapy group included three cycles of cisplatin and fluorouracil. Surgery was performed two to four weeks after the completion of the third cycle; patients also received two additional cycles of chemotherapy after the operation. Patients randomly assigned to the immediate-surgery group underwent the same surgical procedure. The main end point was overall survival. RESULTS: Of the 440 eligible patients with adequate data , 213 were assigned to receive preoperative chemotherapy and 227 to undergo immediate surgery. After a median possible study time of 55.4 months, there were no significant differences between the two groups in median survival: 14.9 months for the patients who received preoperative chemotherapy and 16.1 months for those who underwent immediate surgery (P=0.53). At one year, the survival rate was 59 percent for those who received chemotherapy and 60 percent for those who had surgery alone; at two years, survival was 35 percent and 37 percent, respectively. The toxic effects of chemotherapy were tolerable, and the addition of chemotherapy did not appear to increase the morbidity or mortality associated with surgery. There were no differences in survival between patients with squamous-cell carcinoma and those with adenocarcinoma. Weight loss was a significant predictor of poor outcome (P=0.03). With the addition of chemotherapy, there was no change in the rate of recurrence at locoregional or distant sites. CONCLUSIONS: Preoperative chemotherapy with a combination of cisplatin and fluorouracil did not improve overall survival among patients with epidermoid cancer or adenocarcinoma of the esophagus.     

Recombinant human erythropoietin reduces the need for erythrocyte and platelet transfusions in pediatric patients with sarcoma: a randomized, double-blind, placebo-controlled trial

OBJECTIVE: To evaluate the effect of recombinant human erythropoietin (EPO) and iron supplementation on transfusion requirements in pediatric patients with sarcoma who were receiving chemotherapy, we performed a double-blind, placebo-controlled, randomized trial. METHODS: Twenty-four pediatric patients with malignant solid tumors were randomly assigned to receive either placebo (saline solution) or EPO for a 16-week study period. The starting dose was 150 IU/kg per dose three times a week and was escalated by 50 IU/kg per dose increments monthly until packed red blood cell (PRBC) transfusion independence was achieved or a dosage of 300 IU/kg per dose was reached. Iron supplementation was prescribed at a dose of 6 mg of elemental iron per kilogram daily. The primary study end point was the comparison of PRBC transfusion requirements in the two groups. RESULTS: Of 24 patients, 20 were evaluable for response. The median PRBC transfusion requirement during the 16-week period was 23 ml/kg in EPO-treated patients versus 80 ml/kg in placebo patients (p = 0.02). The median number of single-donor platelet units transfused was zero in the EPO-treated patients compared with four in the placebo group (p = 0.005). No statistical difference in the intensity of bone marrow suppression was seen, as measured by the median number of complete blood cell counts with an absolute neutrophil count of < 1000 cells/microliter. CONCLUSIONS: Treatment with EPO and iron significantly reduces PRBC transfusions in pediatric patients receiving concomitant chemotherapy for malignant sarcomas. A decrease in the number of platelet transfusions was also seen and deserves further study.
