The role of high-dose oral iron supplementation during erythropoietin therapy for anemia of prematurity.

OBJECTIVE: To assess whether a high intake of oral iron would increase the effect of recombinant human erythropoietin (rHuEPO) on hemoglobin synthesis. METHODS: We studied 30 preterm infants (gestational age 29+/-1.8 weeks, birth weight 1161+/-200 g, at age of 28+/-10 days) who were randomly assigned to receive either 8 mg/kg per day (n=15) or 16 mg/kg per day of oral iron during a course of rHuEPO therapy (900 microg/kg per week) for a duration of 4 weeks. Both groups were comparable in regard to clinical and laboratory data at the time of enrollment. RESULTS: rHuEPO caused a significant increase in reticulocyte count in the low- and high-dose iron groups, 17.1+/-5.3 to 34.7+/-9.2 and 16.3+/-3.3 to 42.5+/-5.6 (10(9)/l), respectively (p<0.05). However, in both groups, hematocrit values remained stable at the end of the study as compared to baseline (0.35+/-0.03% vs. 0.30+/-0.03%, 0.35+/-0.05% vs. 0.30+/-0.03%, NS) and in both groups there was a comparable and significant decrease in ferritin level (259+/-109 to 101+/-40 and 168+/-54 to 69+/-38 microg/l, respectively; p<0.01). The rates of bloody stools without any evidence of necrotizing enterocolitis were not significantly different between the two treatment groups (1/15 vs. 4/15, NS). CONCLUSION: We conclude that a higher dose (16 mg/kg per day) of oral iron is not more beneficial when compared to a lower dose (8 mg/kg per day) during rHuEPO therapy for anemia of prematurity. Further studies will define the optimal dosage and route of administration of iron supplementation during rHuEPO therapy.     

Treatment results and prognostic factors for cervical cancer patients treated by radiochemotherapy with weekly cisplatin

OBJECTIVE: This retrospective trial aims to report the treatment results of patients with locally advanced cervical cancer treated by concomitant radiochemotherapy with weekly cisplatin. METHODS: Between October 1999 and December 2003, 81 patients with FIGO Stages IB-IVA were treated at Ege University Faculty of Medicine Department of Radiation Oncology by radiochemotherapy with weekly cisplatin (40 mg/m2). Intracavitary high-dose rate brachytherapy was applied to 76 patients (93.8%) and five patients (6.2%) were treated with external radiotherapy alone. Early and late side-effects of the treatment were analyzed according to RTOG-EORTC criteria. RESULTS: Median age was 55 years and the most frequent histology was epidermoid carcinoma. Median follow-up time was 42 months. Five-year overall, disease-free and local relapse-free survival rates were 69%, 77%, and 82%, respectively. The presence of low Hgb level (< 12 g/dl), bulky tumor (> 4 cm), poor performance status, pelvic nodal involvement and limited early response to treatment had a significant impact on the local failure rate. Prognostic factors influencing disease-free survival were bulky tumor, performance status, pelvic nodal status, pretreatment Hgb level and limited early response to treatment. A significantly higher 5-year overall survival rate was observed in patients with good performance status, without pelvic nodal involvement, normal pretreatment Hgb level and complete response to treatment. Grade 3-4 side-effects were not observed in any patients. The most frequent acute side-effects were leukopenia, anemia, nausea and vomiting. Long-term side-effects were observed in 54% of patients. Conclusion: This series suggests that radiochemotherapy with weekly cisplatin is an effective and a safe treatment in locally advanced cervical cancer.     

Erythropoietin in the treatment of iron deficiency anemia during pregnancy

The aim of this study was to investigate the efficacy of recombinant human erythropoietin (rHuEPO) combined with parenteral iron, in the treatment of moderate and severe iron deficiency anemia during pregnancy. Twenty-six pregnant women, who had been ineffectively treated with iron supplementation alone for at least 8 weeks, were enrolled. They met the following criteria for inclusion in the study: hemoglobin (Hb) concentration <8.5 g/dl, evidence of iron deficiency anemia, and absence of other pregnancy complications, or severe systemic diseases. The treatment protocol comprised of a combination therapy with 150 IU/kg rHuEPO subcutaneously three times per week and 100 mg parenteral iron daily, for a total period of 4 weeks. Nineteen out of 26 women (73%) showed a quick response, with Hb reaching normal levels within the first 2 weeks of treatment. They displayed an average of 3.17 g/dl increase in Hb concentration during the total period of therapy, with 3.0 g/dl increase within the first 2 weeks. In 5 women (19.2%) there was no significant increase in Hb levels, while in 2 women (7.6%) a further decline in Hb concentration was observed, that necessitated a blood transfusion. In conclusion, rHuEPO combined with parenteral iron is an effective treatment for moderate and severe iron deficiency anemia during pregnancy, with minimal adverse or side effects. It may serve as an alternative to blood transfusion, or in cases of resistant anemia that are not effectively treated by iron supplementation alone. However, further studies are needed to investigate the poor response observed in about 25% of treated patients.     

Erythropoietin Treatment under Polychemotherapy in Patients with Gynecologic Malignancies: A Prospective, Randomized, Double-Blind Placebo-Controlled Multicenter Study

In order to examine the influence of erythropoietin (rHuEPO) on serum hemoglobin levels, transfusion requirements, and quality of life in patients with gynecologic malignancies under polychemotherapy and chronic tumor anemia (hemoglobin <11 g/dl), we performed a prospective, randomized, double-blinded placebo-controlled clinical trial. Between October 1992 and October 1993, 35 patients from 5 gynecologic departments were entered into this trial. Inclusion criteria were hemoglobin level <11 g/dl, ferritin level >29 ng/ml, stool negative for occult blood, and life expectancy for more than 3 months. Patients received either 150 U/kg body wt rHuEPO (Erypo by Cilag-Janssen) sc three times a week for 12 weeks (n= 23) or a placebo (n= 12). If the hemoglobin levels of the 4th, 8th, or 12th week were >2 g/dl above the baseline value and/or >12 g/dl, the patient was classified as a responder. Patients who required blood transfusions (hemoglobin <8 g/dl, erythrocytes <3 × 10⁶/ml, or clinical symptoms of anemia) were classified as nonresponders. A nonvalidated quality of life questionnaire was completed by the patient at the beginning of the treatment and then every fourth week before receiving chemotherapy. In the rHuEPO group 56.6% of the patients responded to the treatment (χ²= 10.79,P= 0.001) and only 5 patients (21.7%) required blood transfusions, whereas 8 of 12 patients in the placebo group (66.6%) had to be transfused (χ²= 6.81,P= 0.009). Quality of life did not differ significantly between the rHuEPO group and the placebo group of patients. Within the rHuEPO group those patients that responded showed a significant increase in physical activity after response in comparison to the preresponsive phase (P= 0.02, pairedttest). We therefore concluded that rHuEPO significantly increases serum hemoglobin levels and decreases transfusions requirements while maintaining quality of life in patients with gynecological malignancies who are undergoing polychemotherapy.     

Intravenous iron therapy in pregnancy anemia: hematological response in relation to gestational age.

This study was undertaken to evaluate the response to parenteral administration of iron in 62 pregnant patients with asiderotic anemia and mean initial hemoglobin (Hb) concentrations (Hb1) of 9.91+/-(SD) 1.13 g/dl. Iron (742+/-366 mg) was administered intravenously, and the response to treatment was classified according to the rise in Hb (VarHb; 0.97+/-0.77 g/dl) and evaluated after 19.5+/-14.6 (range 4-57) days. It was found that the VarHb was inversely correlated with the Hb1 value (r = -0.46; p<0.001) and only weakly correlated with the number of vials administered. In addition, two-cluster analysis of patients on the basis of VarHb and gestational age resulted in two significantly different groups (p<0.001): >28 weeks of pregnancy (n = 39, group 1: 1.27+/-0.66, range 0.1-3.3 g/dl) and < or =28 weeks of pregnancy (n = 23, group 2: 0.45+/- 0.69, range 0.4-2.3 g/dl). No difference was found between groups 1 and 2 in relation to Hb1, iron dose, and therapy duration. The number of patients with VarHb >0.8 g/dl was found to be higher in group 2 than in group 1: 31/39 versus 8/23 (p<0.001). These results indicate that the response to intravenous iron therapy in pregnancy anemia is related to Hb1 level and gestational age at the onset of treatment and probably depends on the erythropoietin response to anemia.     

Concurrent radiotherapy with paclitaxel/carboplatin chemotherapy as a definitive treatment for squamous cell carcinoma of the uterine cervix

OBJECTIVES: To evaluate the toxicity and the efficacy of paclitaxel/carboplatin chemoradiotherapy as a definitive treatment for squamous cell cancer of the uterine cervix. METHODS: From March 2000 to January 2004, 33 patients with squamous cell cancer of the uterine cervix were treated with concurrent chemoradiotherapy including 2 cycles of paclitaxel (135 mg/m(2)) and carboplatin (area under the time-concentration curve 4.5 mg min/ml) at 4-week interval. Seven patients received adjuvant chemotherapy with the same chemotherapeutic regimen. All patients received external beam radiotherapy with 41.4-51.4 Gy (median 50.4 Gy) to the whole pelvis. Twenty-eight patients received boost irradiation to the cervix by brachytherapy with 25.6-43.3 Gy (median 34.6 Gy) and 5 patients by external beam radiotherapy with 10.8-14.4 Gy (median 14.4 Gy). RESULTS: A median follow-up period was 27 months (range: 6-53 months). Acute hematological toxicity of grade 3 or 4 developed in 20 patients (61%), and acute gastrointestinal toxicity of grade 3 developed in 1 patient (3%). Vesicovaginal fistula occurred in 2 patients (6%). All patients achieved objective response (CR 70%, PR 30%) in 2 months after termination of treatment. One patient had a local progression in cervix, and 4 patients developed distant metastases. The 3-year estimated disease-free survival rates for stages I-IIA, IIB, III and IV were 67%, 91%, 88% and 50%, respectively. The 3-year estimated survival rates for stages I-IIA, IIB, III and IV were 89%, 91%, 88% and 50%, respectively. CONCLUSION: Concurrent chemoradiotherapy with paclitaxel and carboplatin is effective to achieve an excellent pelvic control.     

Prognostic factors in definitive radiotherapy of uterine cervical cancer

PURPOSE: To determine the prognostic factors related to local control and survival in 257 patients with uterine cervical cancer treated with definitive radiotherapy (RT). MATERIALS AND METHODS: The medical records of 257 patients treated with definitive RT from January 1987 to December 1998 were reviewed retrospectively. Pretreatment and treatment parameters were analyzed to determine their prognostic value onlocal control and survival. Survival analyses were performed using the Kaplan-Meier method. The log-rank test was used for univariate analyses and the Cox regression model was used for multivariate analyses. RESULTS: Median age was 55 (range 25-82). Squamous cell carcinoma was the most common histologic type (89.1%). The distribution per FIGO Stage was IIA: 13.2%; IIB: 54.9%; IIIA: 3.9%; IIIB: 19.8%; IVA: 8.2%. Ninety-eight patients (38.1%) were treated with external RT alone; 134 (52.1%) received both external RT and intracavitary brachytherapy; 21 (8.2%) received external RT and chemotherapy and four (1.6%) received external RT, intracavitary brachytherapy and chemotherapy. Median follow-up duration was 50 months (range 24-155 months). The failure rate was 51.8% with 26.5% of patients having only local failure, 16.7% only distant failure and 8.6% both local and distant failure. Five-year local progression-free, disease-free and overall survival rates were 58.1%, 44% and 63.7%, respectively. In univariate analysis the prognostic factors identified for local progression-free survival were histology (p = 0.008), FIGO stage (p < 0.001), initial hemoglobin (Hgb) level (p = 0.001), total radiation dose (p = 0.039), use of brachytherapy (p = 0.001) and of chemotherapy (p = 0.037) and enlarged paraaortic nodes (p = 0.016). In multivariate analysis the prognostic factors were FIGO stage (p = 0.014), initial Hgb level (p = 0.040), and use of brachytherapy (p = 0.013). The prognostic factors identified for disease-free survival were histology (p = 0.011), FIGO stage (p < 0.001), initial Hgb level (p < 0.001), use of brachytherapy (p = 0.001) and of chemotherapy (p = 0.014) in univariate analysis; and FIGO stage (p < 0.001), initial Hgb level (p = 0.017), total tumor dose (p = 0.034), use of brachytherapy (p = 0.006) and of chemotherapy (p = 0.021) in multivariate analysis. Factors influencing overall survival were FIGO stage (p < 0.001), initial Hgb level (p = 0.006), overall treatment time (p = 0.028), total tumor dose (p = 0.007), use of brachytherapy (p < 0.001), enlarged paraaortic (p < 0.001) and pelvic nodes (p = 0.004) in univariate analysis; and FIGO stage (p < 0.001), overall treatment time (p = 0.031), enlarged paraaortic (p = 0.007) and pelvic lymph nodes (p = 0.043) in multivariate analysis. CONCLUSION: Definitive RT is an effective treatment for patients with uterine cervical cancer. There are many prognostic factors influencing treatment outcome. Brachytherapy and chemotherapy must be added in appropriate patients to improve the outcome. Future prospective trials should be undertaken to confirm the validity of these factors and to individualize the treatment strategy for every patient.     

Does pretreatment human papillomavirus (HPV) titers predict radiation response and survival outcomes in cancer cervix?--a pilot study

OBJECTIVE: To evaluate if pretreatment HPV titers in cancer cervix could predict radiation response and survival outcomes. METHODS: Twenty-one patients of cancer cervix were treated by radiotherapy (RT) alone. HPV titers were estimated using DNA Hybrid Capture II test. Loco-regional response at 1 month of RT--complete or partial response (CR and PR respectively) and survival outcomes--local disease-free (LDFS), disease-free (DFS) and overall (OS) survivals were evaluated against pre- and posttreatment HPV titers. RESULTS: Pretreatment HPV titers ranged from 0.81 to 3966.10 RLU/cut off (mean +/- SD: 1264.39 +/- 1148.22, median: 1129.98). Of the demographic features evaluated, mean HPV titers were significantly different only for patients achieving CR or PR at completion of RT (mean +/- SD for CR vs. PR: 1616.31 +/- 1146.86 vs. 384.57 +/- 538.80, P = 0.022). HPV titers at end of RT ranged from 0.12 to 487.42 RLU/cut off (mean +/- SD: 37.31 +/- 108.60, median: 2.33). Patients with higher pretreatment HPV titers (>1000 RLU/cutoff) had a higher CR (P = 0.022) and better survival compared to those with < or =1000 RLU/cutoff (LDFS, P = 0.004; DFS, P = 0.005; OS, P = 0.012). At completion of RT, those having > or =99.5% fall in HPV had superior survival outcomes than those with <99.5% reduction (LDFS, P = 0.002; DFS, P = 0.002; OS, P = 0.004). CONCLUSIONS: Higher pretreatment HPV titers (>1000 RLU/cutoff) could be considered as a predictor of radiotherapy response and survival in cancer cervix. A reduction in these titers to 99.5% of their baseline values at end of radiotherapy is also associated with better survival outcomes.     

Is pretreatment hemoglobin level a predictor of complete response to salvage chemotherapy for recurrent platinum-pretreated ovarian carcinoma?

PURPOSE OF INVESTIGATION: The aim of this retrospective study was to correlate some patient characteristics at relapse, including also baseline hemoglobin levels, with complete response rate and survival following second-line chemotherapy for recurrent platinum-pretreated ovarian carcinoma. METHODS: The investigation was conducted on 63 patients who received salvage chemotherapy with different agents for clinically detectable recurrent ovarian carcinoma following initial surgery and first-line platinum-based chemotherapy. Some patient characteristics at relapse (patient age, serum CA 125 level, baseline hemoglobin level, number of recurrence sites, ascites, platinum-free interval, and treatment-free interval) were related to complete response rate to salvage chemotherapy and survival after recurrence. Median baseline hemoglobin level was 11.6 g/dl (range, 7.5-15.0 g/dl). RESULTS: Second-line chemotherapy obtained a complete response in 17 (27.0%) patients and a partial response in 11 (17.5%), whereas stable disease and progressive disease were detected in 19 (30.1%) and 16 (25.4%) patients, respectively. By univariate analysis, complete response rate was related to baseline hemoglobin level (p = 0.0019), platinum-free interval (p = 0.0012) and treatment-free interval (p = 0.0048). Multiple logistic regression showed that platinum-free interval (p = 0.0107) and baseline hemoglobin level (0.0312) were independent predictors of complete response. Patients with baseline hemoglobin levels >11.6 g/dl had a 5.338 higher chance of obtaining a complete response when compared to those with lower hemoglobin values. The platinum-free interval was the only independent prognostic variable for survival after recurrence (p = 0.0141), whereas baseline hemoglobin level was not related to survival at univariate nor at multivariate analysis. CONCLUSIONS: Baseline hemoglobin level is an independent predictor of complete response to salvage chemotherapy in patients with recurrent platinum-pretreated ovarian carcinoma. Attention must be paid to anemia correction in these patients, with the aim of improving both the chance of response to salvage treatment and the quality of life.     

Postoperative adjuvant concurrent chemoradiotherapy improves survival rates for high-risk, early stage cervical cancer patients

OBJECTIVE: This study was undertaken to evaluate the efficacy of postoperative concurrent chemoradiotherapy (CCRT) and to investigate the recurrence and survival rates after adjuvant CCRT in high-risk early cervical cancer (stages IA2, IB, IIA) patients who were treated by radical hysterectomy and pelvic lymphadenectomy. METHODS: From July 1994 to June 2001, we retrospectively reviewed the medical records of 151 patients who had undergone radical abdominal hysterectomy with pelvic lymphadenectomy and paraaortic lymph nodes dissection at Ajou University Hospital for early cervical cancer (stages IA2, IB, IIA). CCRT was performed in 30 patients with high-risk factors such as positive pelvic lymph nodes, parametrial involvement, or positive surgical margins. Adjuvant chemotherapy consisted of cisplatin (70 mg/m(2) on day 1) and 5-fluorouracil (5-FU; 1000 mg/m(2) on days 2-5) for four cycles every 4 weeks beginning 2-3 weeks after surgery. Pelvic radiotherapy was started concurrently at the second and third cycle of chemotherapy. We also analyzed the recurrence pattern and survival rates of 114 patients (control group) who received no adjuvant therapy after surgery. The mean follow-up period was 49 months (24-98 months). RESULTS: There were recurrences in three patients after CCRT (10%) and in five patients in the control group (4.4%). The actuarial 5-year overall survival rates for patients in CCRT and control group were 96.7% vs. 97.7%, respectively. The progression-free survival rates were 88.7% for the high-risk group and 95.4% for the non-high-risk group. CONCLUSIONS: This study confirms good local control and 5-year overall and progression-free survival rates in high-risk cervical cancer patients after CCRT, which is comparable with the results of the control group. Our results indicate that adjuvant concurrent chemoradiotherapy seems to be effective in stages IA2-IIA cervical cancer patients with high-risk factors.     

Pre-chemotherapy hemoglobin levels and survival in patients with advanced epithelial ovarian cancer who received a first-line taxane/platinum-based regimen: results of a multicenter retrospective Italian study

OBJECTIVE: The aim of this retrospective multicenter study was to assess whether the pre-chemotherapy hemoglobin levels have any impact on the clinical outcome of patients with advanced epithelial ovarian cancer who received a first-line taxane/platinum-based regimen. METHODS: The study was conducted on 315 patients who underwent initial surgery followed by taxane/platinum-based chemotherapy for FIGO stage IIc-IV epithelial ovarian cancer. All the patients had ECOG performance status 0-1 at presentation. The median follow-up of survivors was 36 months (range, 6-120 months). RESULTS: The 25%, 50%, and 75% quantiles of hemoglobin levels before starting first-line chemotherapy were 10.2, 11.4, and 12.3 g/dl, respectively. Residual disease after initial surgery (>1 cm versus 12.3 g/dl) were inversely related to overall survival at univariate (P = 0.03) but not at multivariate analysis. CONCLUSIONS: This investigation showed that hemoglobin levels before starting first-line taxane/platinum-based chemotherapy are not an independent prognostic factor for overall survival in patients with advanced epithelial ovarian cancer.     

Single-dose darbepoetin administration to anemic preterm neonates.

OBJECTIVE:Darbepoetin is longer acting and more potent than recombinant erythropoietin (rEpo). In certain situations, preterm neonates might benefit from rEpo, and for such patients darbepoetin would require fewer doses at a lower cost. However, the proper dose and dosing interval have not been established.STUDY DESIGN:We performed a prospective trial in two level III Neonatal Intensive Care Units. Patients <32 weeks gestation at birth, with a birth weight (BW) <1500 g, were eligible for participation if they were >21-days-old and had a hemoglobin (Hgb) concentration 相似文献   

Placental umbilical cord blood transfusion: a new method of treatment of patients with diabetes and microalbuminuria in the background of anemia

Diabetes mellitus is the commonest endocrine disease in all populations and all age groups. It is a syndrome of disturbed intermediary metabolism caused by inadequate insulin secretion or impaired insulin action, or both. Anemia is a common accompaniment of diabetes, particularly in those with albuminuria justifying tubulointestitial injury or reduced renal function. There are other additional factors present in diabetes, which may contribute to the development of an increased risk of anemia. Cord blood, because of its rich mix of fetal and adult hemoglobin, high platelet and WBC counts, hypo-antigenic nature, altered metabolic profile and high affinity for oxygen, may be an ideal choice for cases of diabetes with severe anemia necessitating blood transfusion. This article presents my team's experience with 78 units of placental umbilical cord whole blood (from 1 April 1999 to April 2005), collected after lower uterine cesarean section (LUCS) from consenting mothers (56 ml-138, ml mean 82 ml +/- 5.6 ml SD, median 84 ml, mean packed cell volume 49.7 +/- 4.2 SD, mean percent hemoglobin concentration 16.6 g/dl +/- 1.5 g/dl SD) and transfused to diabetes patients with microalbuminuria and severe anemia necessitating transfusion. After collection, the blood was transfused, in most cases immediately after completion of the essential norms of transfusion. In rare cases, it was kept in the refrigerator and transfused within 72 hours of collection to a suitable recipient. For inclusion in this study, the patient's percent plasma hemoglobin had to be 8 g/dl or less (the pretransfusion hemoglobin in this series varied from 5.2 g/dl to 7.8 g/dl) in the background of type two diabetes (fasting sugar 200 mg or more), along with features of microalbuminuria (albumin excretion 30-299 mg/g creatinine). This study included 39 informed consenting patients (22 males + 17 females, aged 48-74 yrs, mean 59.6 yrs). The patients were randomized into two groups: Group A (control cases N = 15, males = 8 and females = 7) and Group B (study group N = 24, males = 14 and females = 10). In Group A the rise of hemoglobin (Hgb) after two units of adult blood transfusion was 1.5 to 1.8 g/dl, as seen after a 72-hour blood sample assessment. The rise of Hgb as noted after 72 hours of two units of freshly collected cord blood transfusion was .6 g/dl to 1.5 g/dl. Each patient received two of four units of freshly collected cord blood transfusion (two units at a time), depending on availability and compatibility. Microalbuminuria was assessed in both groups after one month of treatment with transfusion and other identical support. The mean result was 152 +/- 18 m SD of albumin per gram of creatinine excreted through 24-hour urine (pre-transfusion mean excretion was 189 +/- 16 mg) in Group A and 103 +/- 16 mg SD of albumin excretion per gram of creatinine in 24-hour excretion of urine in Group B (pretransfusion mean excretion was 193 +/- 21 mg). Univariate analysis using Fisher's exact test was performed for the results of Groups A and B. The difference between Group A and B values and its comparison with the pre-transfusion microalbuminuria appeared to be statistically significant (p < less than .003). We have not encountered any clinical, immunological or non-immunological reaction so far in either group. Fetomaternal cell traffic has been implicated as the cause of scleroderma in mothers delivering male babies. In the present series, we did not see any such rare and unusual complication due to neonatal blood transfusion in the adult system in Group B patients in the six years from the initiation of the study.     

Serum copper and zinc levels in patients with cervical cancer

The serum copper (SCL) and zinc (SZL) levels were measured in 99 patients with cervical cancer and 50 patients with uterine myoma as controls. The mean SCL in the control group was 109.4 +/- 17.4 micrograms/ml as compared to 117.1 +/- 14.6 micrograms/dl and was not significant (NS) in 17 carcinoma in situ (CIS) patients, 142.3 +/- 14.2 micrograms/dl in 30 stage I patients (p less than 0.001), 159.0 +/- 16.6 micrograms/dl in 22 stage II patients (p less than 0.001), 171.6 +/- 25.7 micrograms/dl in 10 stage III or IV patients (p less than 0.001), and 166.2 +/- 32.2 micrograms/dl in 20 recurrent patients (p less than 0.001). The SCL returned to control level 2 weeks after surgical treatment for the stage I and II patients (mean 110.6 +/- 19.6 and 108.7 +/- 20.4 micrograms/dl, respectively, p less than 0.001). The SZL was 97.2 +/- 15.8 micrograms/dl in control patients and only showed a significant decrease in stage III or IV and recurrent patients (67.2 +/- 16.6 and 70.4 +/- 17.2 micrograms/dl, respectively). Concerning the copper/zinc ratio, the control group was 1.13 +/- 0.07 as compared to 1.17 +/- 0.07 in CIS (p = 0.06), 1.51 +/- 0.24 in stage I (p less than 0.001), 1.85 +/- 0.37 in stage II (p less than 0.001), 2.66 +/- 0.61 in stage III or IV (p less than 0.001), and 2.50 +/- 0.75 in recurrent patients (p less than 0.001). Taking mean +/- 2.5 SD of the control values as cut off points, the percentages of the recurrent patients with abnormal SCL, SZL, and a Cu/Zn ratio were 65, 30 and 90%, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Administration of recombinant human erythropoietin in patients with gynecological cancer before radical surgery

The purpose of this prospective study was to investigate the efficacy of preoperative administration of recombinant human erythropoietin in patients with gynecological cancer. METHODS: The study included 38 women with gynecological cancer who were divided randomly in two groups. Study group A included 20 women with gynecological cancer who received recombinant human erythropoietin (rHuEPO) plus iron supplementation for ten days before surgery and five days postoperatively. Group B (controls) included 18 patients who received only iron supplementation for the same time period. Blood samples were obtained on days -10, -3, 0, +3, +5, +10. RESULTS: The mean hemoglobin level was significantly higher in group A than in group B on the day of the operation and remained significantly higher postoperatively while an inverse relationship was observed for mean ferritin values in the two groups. CONCLUSION: Preoperative administration of rHuEPO in patients with gynecological cancer seems to be effective in the blood management of these patients.     

Effect of intravenously administered iron sucrose on the prevention of anemia in the cervical cancer patients treated with concurrent chemoradiotherapy

OBJECTIVE: The incidence of anemia in the cervical cancer patients treated with concurrent chemoradiotherapy is estimated to be more than 50%. Transfusion has been the mainstay of hematologic support with its inherent hazards including infection and transfusion reaction. The aim of this study was to examine the impact of intravenously administered iron sucrose on the prevention of anemia in the cervical cancer patients undergoing concurrent chemoradiotherapy. METHODS: From Oct. 2003 to Dec. 2005, 75 patients were treated with platinum-based concurrent chemoradiotherapy. Thirty patients received 200 mg of iron sucrose intravenously (study group) and 45 patients did not receive it (control group). RESULTS: In the study group, only 12 (40.0%) patients required blood transfusions, whereas 29 (64.0%) patients in the control group needed blood transfusions (P=0.04). Mean transfusion units were 1.87 units in the study group and 3.58 units in the control group (P=0.04). CONCLUSION: This study showed that intravenous supply of iron sucrose could decrease transfusion requirement and increase serum hemoglobin level in patients with cervical carcinoma undergoing concurrent chemoradiotherapy. Therefore, intravenously administered iron sucrose would be effective in the prevention of anemia of cervical cancer patients receiving concurrent chemoradiotherapy.     

The role of pretreatment squamous cell carcinoma antigen level in locally advanced squamous cell carcinoma of the uterine cervix treated by radiotherapy

The purpose of this study was to determine the pretreatment serum squamous cell carcinoma antigen (SCC-ag) level as a generally applicable measurement in predicting and estimating the treatment outcome of patients with locally advanced SCC of the cervix. Three hundred fifty-two patients with stage IIB-IVA SCC of the cervix were managed with both external irradiation and high-dose rate intracavitary brachytherapy. A significantly higher median SCC-ag was seen in association with increasing stage, tumor size, and lymph node involvement. The difference in disease-free survival (DFS) between stages IIB and III patients was not statistically significant with SCC-ag level <2 ng/mL. In multivariate analysis, median SCC-ag level (> or =6.0 ng/mL) and lymph node metastases had significant independent effects on absolute survival and DFS. A direct linear relationship (y=-2.932x+ 84.896) existed between the median SCC-ag of groups distributed by pretreatment prognostic factors and the 5-year DFS rate. The 5-year DFS rate as a function of SCC-ag level defined by cervix size, lymph node status, and hydronephrosis was obtained from a formula combining risk scores and the baseline survival function. From the obtained formulas, we can objectively estimate the treatment outcome in patients with locally advanced squamous cell cervical cancer.     

First-line chemotherapy with paclitaxel and platinum for advanced and recurrent cancer of the cervix--a phase II study

OBJECTIVE: The aim of this study was to assess the role of first-line chemotherapy with paclitaxel and platinum in the treatment of advanced or recurrent cervix cancer. METHODS: Twenty patients with advanced or recurrent cancer of the cervix with no prior chemotherapy and measurable disease were entered in a phase II trial from September 1995 to September 1998. Seventeen patients were treated with paclitaxel at 135 mg/m(2) over 24 h followed by cisplatin at 75 mg/m(2) every 4 weeks. Three patients with impaired renal function were treated with paclitaxel at 135 mg/m(2) over 3 h with carboplatin at 300 mg/m(2). RESULTS: A clinical response rate of 45% was noted (two complete responses and seven partial responses) with a median duration of 6 months (range: 1.5-9). The median progression-free interval and overall survival in patients with a clinical response was 10.5 and 13 months, respectively, compared to 4 (P = 0.015) and 6 months in the nonresponders (P = 0. 14). Seven of nine patients (77.8%) with a clinical response are alive. Patients with recurrences outside the radiation field had twice the response rate (60%) than that of those within the radiated field. The chemotherapy was well tolerated; the most significant toxicity was grade 3/4 neutropenia (55%). No patient had discontinuation of chemotherapy due to toxicity. CONCLUSIONS: First-line chemotherapy with paclitaxel and platinum for advanced and recurrent cervix cancer is promising and deserves consideration for large phase III trials.
