RESUMO

BACKGROUND: Preoperative fasting and surgery cause metabolic stress, insulin resistance with ketosis, and postoperative nausea and vomiting (PONV). Oral carbohydrate loading strategy (CHO) improves outcomes in labor and general surgery. We aimed to compare the effectiveness of CHO with standard fasting in patients undergoing elective cesarean delivery (CD) under spinal anesthesia. METHODS: A single-center, parallel, prospective randomized controlled trial (RCT) was conducted in a tertiary university obstetrics department at Pomeranian Medical University in Szczecin, Poland. Patients were randomly assigned (1:1 ratio) to the CHO group (oral carbohydrate 2 h before elective CD, n = 75) or the SF group (control-standard fasting, n = 73). The main outcome measures were incidence and severity of PONV at 6 and 24 h after CD, time to the first peristalsis, time to first bowel movement, and biochemical parameters indicating ketosis in mothers and their children. RESULTS: A total of 148 adult females with singleton pregnancies undergoing elective CD under spinal anesthesia (ASA I and II) were included in the final analysis. At 24 h after CD, 8.0% from the CHO group vs. 20.55% reported three or more episodes of vomiting or dry retching as compared to patients in the SF group (p = 0.041). Preoperative CHO supplementation decreased preoperative feelings of hunger (p < 0.001) and thirst (p < 0.001). Laboratory results in the CHO group showed higher plasma pH (p = 0.001) and glucose (p < 0.001), lower F2-isoprostane in plasma (p = 0.049) and urine (p = 0.018), lower urine F2-isoprostane/creatinine ratio (p = 0.045) than in the SF group. HOMA-IR (p < 0.001) and lactate (p < 0.001) were higher in the CHO group than in the control group. CONCLUSIONS: There was no significant difference in the incidence or severity of early PONV at 6 h. The incidence of vomiting or dry retching at 24 h after cesarean delivery was lower in the CHO group as compared to standard starvation, but the combined results of PONV frequency and severity on the Wengritzky scale did not differ between the two study groups. Preoperative CHO supplementation decreased preoperative feelings of hunger and thirst, enhancing the comfort of pregnant women. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT04069806.

RESUMO

INTRODUCTION: Cervical insufficiency accounts for 15% of recurrent pregnancy losses between 16 and 28 weeks of gestation. The aim of the study is to verify the effectiveness of emergency double-level cerclage with vaginal progesterone in cervical insufficiency treatment in terms of the prevention of preterm delivery before 34 weeks of gestation. METHODS AND ANALYSIS: This trial is a multicentre, non-blinded, randomised study with 1:1 allocation ratio. The study is conducted at tertiary perinatal care departments in Poland. It will include patients with cervical insufficiency with the fetal membranes visible in the open cervical canal or protruding into the vagina between 16+0 and 23+6 weeks of pregnancy. They will be randomised into two arms: emergency single-level cerclage with vaginal progesterone or double-level cerclage with vaginal progesterone. All will be administered antibiotics and indomethacin. The primary outcome is the rate of deliveries below 34+0 weeks of gestation, while secondary outcomes include gestational age at delivery, neonatal outcomes, maternal outcomes according to the Core Outcome Set for Evaluation of Interventions to Prevent Preterm Birth and cerclage procedure complications. The planned number of participants according to the power analysis is 78. ETHICS AND DISSEMINATION: The study protocol was written in accordance with the Standard Protocol Items: Recommendations for Interventional Trials statement. It was created according to the requirements of the Declaration of Helsinki for Medical Research involving Human Subject. Ethical approval was obtained from the Ethics Committee of the Centre of Postgraduate Medical Education (no. 1/2022). The study protocol was approved and published by ClinicalTrials.gov (posted on 24 February 2022). All participants gave a written informed consent. After completion of the study its results will be published in a peer-reviewed English language journal. TRIAL REGISTRATION: NCT05268640.

RESUMO

(1) Aim: Ultrasound is the gold standard for assessing fetal growth disorders. The relationship between high sFlt-1/PlGF scores and LBW (low birth weight) was described. In this study, we attempted to assess whether uric acid could be used as a secondary marker in estimating the pregnancy risk associated with LBW. (2) Material and methods: 665 pregnant women with a suspected or confirmed form of placental insufficiency were enrolled. In each of the patients, sFlt-1 and PlGF and uric acid levels were determined. Patients were divided into two groups according to birth weight below and above the third percentile for the given gestational age with the criteria of the neonatal definition of FGR (fetal growth restriction). (3) Results: A significant negative correlation between neonatal birth weight and the uric acid level across the entire study group was observed. We found a significant negative correlation between neonatal birth weight and the uric acid level with birth weights < 3rd percentile. (4) Conclusions: There is a significant link between the uric acid concentration and LBW in the group with placental insufficiency. Uric acid can improve the prediction of LBW. An algorithm for LBW prognosis that makes use of biophysical (ultrasound) and biochemical (uric acid level, angiogenesis markers) parameters yields better results than using these parameters separately from each other.

RESUMO

Results: For the cut-off point >1 : 150, 86 women at an increased risk of eo-PE using algorithm 1 were identified. Of these 86 patients, 83 (96%) were identified using algorithm 2, 62 (72%) using algorithm 3, and 60 (69%) using algorithm 4. In addition, it was demonstrated that between 21% and 29% of women at a low risk of eo-PE could be given acetylsalicylic acid if a screening test was used that did not account for PlGF. Conclusions: In order to provide the highest level of health care to pregnant women, it is extremely important that full screening for eo-PE should be ensured. The cheapest algorithm based only on MAP and UtPI resulted in our patients being unnecessarily exposed to complications.

RESUMO

INTRODUCTION: Angiogenic markers (sFLt1 and PlGF) are altered in preeclampsia and related placental insufficiency syndromes. The utility of these markers in various types of placental insufficiency is still not well known. AIMS: We analyzed blood specimens from 918 women with suspected or confirmed preeclampsia, HELLP syndrome, abruptio placenta, SGA, gestational hypertension for angiogenic markers - sFLT1, PlGF, sFlT1/PlGF ratios and studied them at various gestational windows. RESULTS: sFlt-1/PLGF ratio shows high sensitivity and specificity in all placental insufficiency cases independent of clinical forms below 34 weeks (AUC 0.964 respectively 0.834 34-37 weeks' and 0.843 >37 weeks). In preeclampsia or HELLP, they maintain a high specificity and sensitivity also after 34 weeks of gestation. SGA prior to 34 weeks' gestation displayed severe placental angiogenesis disorders, with their share amounting to 78%. After 34 weeks, this share dropped to only slightly above 50%, and after the 37th week, a mere 38%. CONCLUSIONS: Placental angiogenesis markers may be useful in diagnosing many forms of placental ischemia syndromes, particularly when the disease presents early in gestation. In late-onset SGA cases, assessment of the diagnostic value of angiogenesis markers requires further analysis.

RESUMO

OBJECTIVES: The objective of this study was to analyze indications for amniocentesis in cases of patients with normal fetal ultrasound results between 11+0 and 13+6 weeks of gestation. MATERIAL AND METHODS: The results of first-trimester screening tests performed between 2014 and 2018 on 6,863 patients of the Prenatal Testing Outpatient Clinic at the Clinical Department of Obstetrics and Gynecology, Pomeranian Medical University, Szczecin, Poland, were analyzed. The inclusion criteria were a singleton pregnancy and normal results of fetal ultrasound between 11+0- and 13+6-weeks' gestation. Depending on the calculated risk of fetal trisomy 21, the patients were divided into three groups (group A = RS > 1:300, group B = RS 1:300 - 1:999, group C = RS ≤ 1:1000). Subsequently, values such as PAPP-A and fß-hCG protein levels and maternal age were analyzed for each of the groups. RESULTS: The patients, 6,310 (91.94%) met the inclusion criteria. A high risk of fetal trisomy 21 was identified for 514 women (8.15%). Group B had 733 (11.62%) and group C 5,063 (80.23%) patients. In group A, an fß-hCG level of ≥ 2.000 MoM was shown for 50.97% of the women. A PAPP-A level ranging from 0.001 to 0.499 MoM was observed for 38.72% of group A patients. The mean maternal age in groups A, B and C was 36.45, 36.08 and 31.64 years, respectively. CONCLUSIONS: In the first-trimester, patients with normal ultrasound results obtained during prenatal screening tests, the main cause of an increased risk of trisomy 21 was elevated PAPP-A and fß-hCG concentrations. According to this paper's authors, in these cases extension of diagnosis to include other gestational complications, e.g. preeclampsia, should be considered.

RESUMO

Pregnancy predisposes to thrombotic hemostasis, reflected in the laboratory as, e.g., increased levels of D-Dimers and fibrinogen, but in physiological pregnancy, the risk of venous thrombosis does not increase. Risk may increase if gestational diabetes mellitus (GDM) or nicotinism coexists. Study aims were to determine reference values for D-Dimers and fibrinogen concentrations in each trimester of pregnancy, corrected for GDM and nicotinism. Subjects and Methods. The study involved 71 pregnant women aged 25-44 y. Venous blood was collected three times: in the first (11-14 weeks), second (20-22 weeks), and third (30-31 weeks) trimesters. D-Dimer concentrations were determined by an enzyme-linked fluorescence assay, fibrinogen concentrations by a coagulation method according to Clauss. Results. Significant increases in D-Dimers and fibrinogen concentrations were observed, increasing with successive trimesters (p ANOVA < 0.0001). Furthermore, a positive correlation between D-Dimers and fibrinogen was detected in the second trimester of pregnancy (r = 0.475; p < 0.0001). In addition, a significantly higher fibrinogen concentration was found in women with GDM compared to without GDM (p = 0.0449). Reference ranges for D-Dimers were established, in trimester order, as follows: 167-721 ng/mL, 298-1653 ng/mL, and 483-2256 ng/mL. After adjusting for risk factors, significantly higher D-Dimer values (mainly second and third trimesters) were obtained: 165-638 ng/mL, 282-3474 ng/mL, and 483-4486 ng/mL, respectively. Reference ranges for fibrinogen were, in trimester order, 2.60-6.56 g/L, 3.40-8.53 g/L, and 3.63-9.14 g/L and, after adjustment for risk factors, 3.34-6.73 g/L, 3.40-8.84 g/L, and 3.12-9.91 g/L. Conclusions. We conclude that the increase in D-Dimers and fibrinogen levels in women with physiological pregnancy was compounded by gestational diabetes (GDM) and nicotinism. Therefore, D-Dimers and fibrinogen pregnancy reference values require correction for these risk factors.

RESUMO

Background Soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) are used as markers of preeclampsia. The aim of this paper was to assess the correlations between the sFlt-1/PlGF ratio values within the <38, 38-85 and >85 brackets and perinatal outcomes in pregnancies that require determination of these markers. Methods A total of 927 pregnant patients between 18 and 41 weeks' gestation suspected of or confirmed with any form of placental insufficiency (preeclampsia, intrauterine growth restriction [IUGR], gestational hypertension, HELLP syndrome, placental abruption) were included in the study. In each of the patients, the sFlt-1/PlGF ratio was calculated. Patients were divided into three groups according to the sFlt-1/PlGF ratio brackets of <38, 38-85 and >85. Results Significantly worse perinatal outcomes were found in the sFlt-1/PlGF >85 group, primarily with lower cord blood pH, neonatal birth weight and shorter duration of gestation. Statistically significant correlations between the values of these markers and the abovementioned perinatal effects were found. Conclusion An sFlt-1/PlGF ratio value of >85 suggests that either preeclampsia or one of the other placental insufficiency forms may occur, which is associated with lower cord blood pH, newborn weight and earlier delivery. Determining the disordered angiogenesis markers and calculating the sFlt-1/PlGF ratio in pregnancies complicated by placental insufficiency may lead to better diagnosis, therapeutic decisions and better perinatal outcomes.

RESUMO

Preeclampsia and conditions associated with impaired placental perfusion develop in almost 10% of all pregnancies. Patho- logic angiogenesis is one of the processes observed in preeclampsia. sFlt-1, PlGF and the sFlt-1/PlGF ratio are new and promising angiogenesis-related biomarkers. Our paper describes the present status of, and clinical practice opportunities for, these factors. According to present data, sFlt-1, PlGF and the sFlt-1/PlGF ratio are very useful tools in assessing placental angiogenesis abnormalities associated with preeclampsia and can be use in clinical practice.

RESUMO

OBJECTIVE: Aging of the placenta is associated with natural processes that impair its functions. The processes are related to both oxidative stress exacerbation and the occurrence of higher concentrations of disordered angiogenesis markers. Both these types of processes are known to play roles in the development of preeclampsia. We attempted to show that natural ageing of the placenta can be one of the cofactors contributing to the development of late-onset preeclampsia. PATIENTS, MATERIALS AND METHODS: 159 pregnant patients were divided into four groups: Two of preeclampsia patients and two of patients with physiological pregnancies, depending on the gestational age. For each group, disordered angiogenesis markers sFlt-1 and PlGF before and after 34 weeks of gestation and in particular stages of gestation were analyzed. RESULTS: Lower PlGF and sFlt-1/PlGF ratio values were found in cases of late-onset preeclampsia. In physiological pregnancies, sFlt-1 values were observed to increase and PlGF values to decrease with gestational age. An association was shown to exist between disordered angiogenesis markers and gestational age both in preeclampsia and physiological pregnancies. CONCLUSIONS: (1) Analyses of disordered angiogenesis markers in early- and late-onset preeclampsia patients and patients with physiological pregnancies allow for a suggestion that natural "ageing of the placenta" and placental hypoperfusion lesions exacerbating with the advancing gestational age are some of the causes of late-onset preeclampsia. (2) Cases of early-onset preeclampsia are associated with more severe changes of disordered angiogenesis marker concentrations, which may be indicative of a more considerable impairment of placental perfusion in such patients. (3) In the course of the physiological pregnancy, there is a gradual increase in sFlt-1 and decrease in PlGF, which implies an elevated angiogenesis disorder that progresses with the gestational age.

RESUMO

The patient's right to refuse blood transfusion must be honoured in case of its clear expression. Some special pharmacologic and/or surgical procedures can be useful in a Jehovah Witness (JW) parturient. In case of excess blood loss the maintenance of peripheral tissue oxygenation is crucial. Only a few hospitals have equipment for blood salvage, and alternative oxygen carriers have potentially lethal side effects. Findings suggest that obstetric facilities should develop special algo-rithms of management in the case of the JW obstetric patient, with written declaration of which elements of blood are not acceptable for the patient, early diagnosis and intensive treatment of anaemia in pregnancy, administration of antifibrinolytic agents before surgery, use of electric surgical tools to restore haemostasis, early detection and aggressive treatment of excessive blood loss and, last but not least, close cooperation between obstetricians and anaesthesiologists, including sharing the information about the patient's refusal of blood transfusion.

RESUMO

We explored whether there was a relationship between the sFlt-1/PlGF ratio in early-late and late-onset SGA patients and whether it is associated with neonatal birth weight. MATERIAL/METHODS: 110 patients who were diagnosed with a fetal weight below the 10th percentile for gestational age and who at the same time delivered neonates with a birth weight below the 10th percentile for gestational age. For each of the patients sFlt-1, PlGF and the sFlt-1/PlGF ratio were studied and uterine artery (UtA) and umbilical artery (UA) Doppler were performed. RESULTS: sFlt-1/PlGF ratios and neonatal birth weight which showed significant negative correlation across the entire population studied (R = -0.46, p < 0.001). In late-onset SGA patients this negative correlation was observed, as well (R = -0.54, p < 0.001) In the group of patients with pregnancies older than 34 weeks and an sFlt-1/PlGF ratio ≥38, we observed a significantly lower neonatal birth weight when compared to the same gestational age group with an sFlt-1/PlGF ratio <38 (2045 g vs 2405 g, p < 0.001). CONCLUSION: Late-onset SGA syndromes are characterized by lower sFlt-1/PlGF ratios, which indicates a lower degree of placental function impairment. The sFlt-1/PlGF ratio can be a predictor of more significant growth disorders and a lower neonatal birth weight. The sFlt-1/PlGF ratio can be helpful in distinguishing between disordered angiogenesis-dependent and other causes of late-onset SGA cases.

RESUMO

Umbilical cord blood (UCB) is a rich source of stem cells, including hematopoietic stem cells (HSCs), mesenchymal stem cells (MSCs), endothelial progenitors cells (EPCs), and very small embryonic-like stem cells (VSELs). These cells most likely are mobilized into UCB in response to hypoxia and delivery stress. We have hypothesized that they may play a role in repairing certain tissue/organ injuries that occur in the newborn child after delivery. Here we asked whether delivery also mobilizes stem cells into maternal blood, as the mother also experiences hypoxia and several types of internal tissue injuries, particularly in the reproductive tract. We observed that the number of HSCs, MSCs, EPCs, and VSELs increases in maternal blood at 24 h after physiological delivery (n = 17). Based on this observation, we propose that delivery stress is associated with an increase in the number of circulating stem cells, not only on the fetal side but also on the maternal side of the fetal-maternal circulatory barrier.

RESUMO

INTRODUCTION: Preeclampsia (PE) and intrauterine growth restriction (IUGR) are separate disease entities that have frequently been reported as sharing the same pathogenesis. In both of them, angiogenesis disorders and generalized endothelial damage with an accompanying inflammation are the dominant symptoms. In this study, we attempted to prove that both these processes demonstrate the same profile in early PE, late PE and IUGR patients, while the only difference is in the degree of exacerbation of the lesions. PATIENTS, MATERIALS AND METHODS: In 167 patients divided into four groups, three of those with early PE, late PE and IUGR and one control group, fms-like tyrosine kinase-1 (sFlt-1), placental growth factor (PlGF), high sensitive c-reactive protein (hsCRP) and fibronectin were determined. The behavior of these parameters in each of the groups was studied, and correlations between them were sought for. RESULTS: Higher concentrations of sFlt-1, hsCRP and fibronectin and a lower concentration of PlGF were found in the study groups compared to the control group. Significant correlations were observed between the factors concerned. CONCLUSIONS: The higher values of disordered angiogenesis markers, endothelial damage markers and inflammatory markers both in the PE and the intrauterine growth restriction (IUGR) groups suggest the existence of shared disorders in the development of these pathologies. The correlations between disordered angiogenesis markers and endothelial damage markers argue in favor of a mutual relationship between these two processes in the development of pathologies evolving as secondary to placental ischemia. The results obtained confirm that the lesion profiles are the same in both PE and IUGR patients, which can be utilized in developing common diagnostic criteria.

RESUMO

Preeclampsia and intrauterine growth restriction are two separate disease entities that, according to numerous reports, share the same pathogenesis. In both, angiogenesis disorders and generalized inflammation are the dominant symptoms. In this study, we hypothesized that both diseases demonstrate the same profile in early preeclampsia, late preeclampsia, and intrauterine growth restriction patients, with the only difference being the degree of exacerbation of lesions. One hundred sixty-seven patients were enrolled in the study and divided into four groups: early preeclampsia, late preeclampsia, and intrauterine growth restriction groups, and one control group. Concentrations of the angiogenesis and inflammatory markers soluble fms-like tyrosine kinase receptor 1, placental growth factor, high-sensitivity C-reactive protein, and interleukin-6 were determined, and the behavior of these markers and correlations among them were studied. Higher concentrations of soluble fms-like tyrosine kinase receptor 1, high-sensitivity C-reactive protein, and interleukin-6 and a lower concentration of placental growth factor were observed in the study groups compared with the control group. No differences in concentrations of the studied markers were found among the study groups but significant correlations were observed. The higher values for the angiogenesis and inflammatory markers both in preeclampsia patients and patients with intrauterine growth restriction of placental origin compared with the control group suggest the existence of the same underlying disorders in the development of these pathologies. The observed mutual correlations for disordered angiogenesis and inflammatory markers are suggestive of a mutual relationship between these processes in the development of pathologies evolving secondary to placental ischemia. The same lesion profile was observed for both preeclampsia and 'placental' intrauterine growth restriction patients, which could be used in developing common diagnostic criteria for pregnant patients.

RESUMO

OBJECTIVE: The shared pathogenesis of placental ischemia entitles us to create a single treatment model. We attempted to develop a unified method for monitoring ischemic placental syndrome patients using Doppler ultrasound of the uterine and umbilical arteries and disordered angiogenesis markers sFlt-1 and PlGF. MATERIAL AND METHODS: 182 pregnant women suffering from the ischemic placental syndrome were divided into four groups depending on the severity of their lesions revealed in the Doppler ultrasound examination and weeks of pregnancy. We analyzed the behavior of clinical and biochemical parameters in these groups and the correlations between the ultrasound examination and the disordered angiogenesis markers. RESULTS: In the group of patients demonstrating more severe Doppler ultrasound lesions, the clinical and biochemical parameters were significantly more expressed, whereas unfavorable obstetric events occurred either earlier or more frequently. Lesions revealed in Doppler occur more commonly in groups before 34th week of pregnancy. Disordered angiogenesis markers are significantly correlated with ultrasound examination results. CONCLUSIONS: A unified method for monitoring the ischemic placental syndrome based on pathogenetic, biophysical (Doppler ultrasound), and biochemical (sFlt-1/PlGF) parameters is feasible and constitutes a valuable supplement to the existing standards, while the high correlations between Doppler ultrasound examinations and both sFlt-1 and PlGF point to a shared pathogenesis of the lesions. Intensity of Doppler changes is connected with time of testing and pregnancy duration.

RESUMO

BACKGROUND: This study aimed to determine the relationships between secretory and endogenous secretory receptors for advanced glycation end products (sRAGE, esRAGE), sRANKL, osteoprotegerin and the interval from diagnosis of threatened premature labor or premature rupture of the fetal membranes to delivery, and to evaluate the prognostic values of the assessed parameters for preterm birth. METHODS: Ninety women between 22 and 36 weeks' gestation were included and divided into two groups: group A comprised 41 women at 22 to 36 weeks' gestation who were suffering from threatened premature labor; and group B comprised 49 women at 22 to 36 weeks' gestation with preterm premature rupture of the membranes. Levels of sRAGE, esRAGE, sRANKL, and osteoprotegerin were measured. The Mann-Whitney test was used to assess differences in parameters between the groups. For statistical analysis of relationships, correlation coefficients were estimated using Spearman's test. Receiver operating characteristics were used to determine the cut-off point and predictive values. RESULTS: In group A, sRAGE and sRANKL levels were correlated with the latent time from symptoms until delivery (r = 0.422; r = -0.341, respectively). The sensitivities of sRANKL and sRAGE levels for predicting preterm delivery were 0.895 and 0.929 with a negative predictive value (NPV) of 0.857 and 0.929, respectively. In group B, sRAGE and sRANKL levels were correlated with the latent time from pPROM until delivery (r = 0.381; r = -0.439). The sensitivity of sRANKL and sRAGE for predicting delivery within 24 h after pPROM was 0.682 and 0.318, with NPVs of 0.741 and 0.625, respectively. Levels of esRAGE and sRANKL were lower in group A than in group B (median = 490.2 vs 541.1 pg/mL; median = 6425.0 vs 11362.5 pg/mL, respectively). CONCLUSIONS: Correlations between sRAGE, sRANKL, and pregnancy duration after the onset of symptoms suggest their role in preterm delivery. The high prognostic values of these biomarkers indicate their usefulness in diagnosis of pregnancies with threatened premature labor.

RESUMO

Uterine rupture is one of the most dangerous obstetric emergencies carrying a high risk for the mother and the fetus. Reports about uterine rupture in pregnancy following previous laparoscopic surgery have not been frequent; however, an increasing rate of the occurrence of this complication has been observed and reviewed in contemporary literature. We report a case of a spontaneous uterine rupture at 22 weeks of gestation in a 25-year old primigravida, who had had a laparoscopic removal of a small, peduncular, asymptomatic myoma located in the right uterine horn 20 months earlier. Ultrasound examination and subsequent urgent laparotomy confirmed a spontaneous uterine rupture with a nonviable fetus in the peritoneal cavity. Women planning to become pregnant should be qualified for laparoscopic myomectomy with special carefulness. Special attention must be paid to the potential solutions that limit the risk of postoperative uterine rupture, if the absolute necessity for the enucleation of myomas during the reproductive age occurs and a decision about laparoscopic intervention is made.

RESUMO

AIM: To compare effects of concomitant radiochemotherapy (RCTh) and radiotherapy (RTh) alone in patients with cervical carcinoma and with 36-months follow-up analysis. MATERIAL AND METHODS: 106 stage IIA-IVA cervical carcinoma women were divided in two groups. RCTh group was treated with teleradiotherapy (50.4 Gy/T), intracavitary brachytherapy (46 Gy), and iv cisplatin (40 mg/m(2)). RTh group was treated with pelvic teletherapy (52-54 Gy/T) and intracavitary brachytherapy (50-55 Gy). RESULTS: In RCTh group absorbed radiation dose was significantly lower (50.4 vs. 52.7 Gy) and the duration of treatment was significantly shorter (45.1 days vs. 47.8 days). There were no statistical differences in both groups in survival (59% in RCTh group vs. 56% in RTh group), response to treatment (86% vs. 90%), local recurrence (42% vs. 49%) metastasis occurrence (21% vs. 17%), anemia (40% vs. 26%), early postradiation reactions in intestines (77% vs. 65%) and bladder (71% vs. 61%) as well as in incidence of rectovaginal (10% vs. 4%) and vesicovaginal formation of fistulas (6% vs. 4%), respectively. There were significant differences between two groups in: nausea (77% vs. 6%), vomiting (65% vs. 3.7%), leucopenia (69% vs. 26%) and thrombocytopenia (35% vs. 9%), and late postradiation bladder effects (94% vs. 74%). RCTh patients with anemia had lower 36-months survival rates (42% vs. 71%), more frequent local recurrences (77% vs. 31%) and metastasis-free survival rates (61% vs. 90%) than RCTh patients without anemia. CONCLUSIONS: RCTh gives better treatment results in patients without than in patients with anemia and higher overall survival rates than RTh in patients without anemia. The only clinical prognostic factor for advance cervical carcinoma is the clinical stage of the disease.
