RESUMEN
A complete gonadal dysgenesis (CGD) with 46,XY karyotype is known as the Swyer syndrome and belongs to the group of 46,XY differences of sex development (DSD). The main problem in patients with Swyer syndrome is the delayed puberty and primary amenorrhea. Moreover, intrabdominal dysgenetic gonads in the patient with genetic material of a Y chromosome may conduce to the development of gonadal tumors, such as gonadoblastoma or germinoma. The management of such patients is based on preventive excision of dysgenetic gonads and long-term hormonal replacement therapy. Sporadic cases are considered more common than familial cases. This paper presents two siblings with Swyer syndrome in whom gonadoblastoma was found. A thorough review of familial CGD with 46,XY DSD in the literature from the last 15 years suggests that the risk of gonadal tumors could be increased in familial compared to sporadic cases (66.6% vs. 15-45%, respectively).
RESUMEN
(1) Background. The purpose of this study is to evaluate the diagnostic accuracy of a quantitative analysis of diffusion-weighted imaging (DWI) and dynamic contrast enhanced (DCE) MRI of mucinous ovarian cancer (MOC). It also aims to differentiate between low grade serous carcinoma (LGSC), high-grade serous carcinoma (HGSC) and MOC in primary tumors. (2) Materials and Methods. Sixty-six patients with histologically confirmed primary epithelial ovarian cancer (EOC) were included in the study. Patients were divided into three groups: MOC, LGSC and HGSC. In the preoperative DWI and DCE MRI, selected parameters were measured: apparent diffusion coefficients (ADC), time to peak (TTP), and perfusion maximum enhancement (Perf. Max. En.). ROI comprised a small circle placed in the solid part of the primary tumor. The Shapiro-Wilk test was used to test whether the variable had a normal distribution. The Kruskal-Wallis ANOVA test was used to determine the p-value needed to compare the median values of interval variables. (3) Results. The highest median ADC values were found in MOC, followed by LGSC, and the lowest in HGSC. All differences were statistically significant (p < 0.000001). This was also confirmed by the ROC curve analysis for MOC and HGSC, showing that ADC had excellent diagnostic accuracy in differentiating between MOC and HGSC (p < 0.001). In the type I EOCs, i.e., MOC and LGSC, ADC has less differential value (p = 0.032), and TTP can be considered the most valuable parameter for diagnostic accuracy (p < 0.001). (4) Conclusions. DWI and DCE appear to be very good diagnostic tools in differentiating between serous carcinomas (LGSC, HGSC) and MOC. Significant differences in median ADC values between MOC and LGSC compared with those between MOC and HGSC indicate the usefulness of DWI in differentiating between less and more aggressive types of EOC, not only among the most common serous carcinomas. ROC curve analysis showed that ADC had excellent diagnostic accuracy in differentiating between MOC and HGSC. In contrast, TTP showed the greatest value for differentiating between LGSC and MOC.
RESUMEN
PURPOSE OF THE REPORT: Ovarian cancer is usually diagnosed in an advanced stage of disease due to the absence of specific symptoms and a lack of sensitive diagnostic methods. Prostate-specific membrane antigen (PSMA) is expressed on prostate cancer cells but can be found in other tumors such as ovarian cancer.The aim of this pilot study was to evaluate the feasibility of using 68 Ga-PSMA-11 PET/CT in detection of ovarian neoplasm before surgical treatment. PATIENTS AND METHODS: Eight women with mean age of 56.0 ± 16.2 years were included in the study. All patients underwent transvaginal ultrasound followed by CT scan of the chest and abdomen as qualification for surgery. Within a 1-week interval, PET/CT was performed on a Siemens Biograph scanner, 60 minutes after injection of 2 MBq/kg 68 Ga-PSMA-11. RESULTS: In 3 cases (37.5%), the 68 Ga-PSMA-11 PET/CT was positive, whereas histological examination confirmed 2 serous ovarian cancer cases and 1 ovarian borderline tumor. The SUV max in the serous ovarian cancer was 8.7 and 4.1, and in the borderline ovarian tumor, it was 13.8. No correlation was found between antigen CA-125 level and 68 Ga-PSMA expression. Range of tumor SUV max was not correlated with stage of disease. The remaining 62.5% (5/8) were negative in 68 Ga-PSMA-11 PET/CT, and histopathology confirmed benign pelvic tumor. CONCLUSIONS: The initial experience supports the potential to use 68 Ga-PSMA-11 in ovarian cancer to differentiate malignant and benign tumors before surgery.This study was approved by the Ethical Committee of the Medical University of Warsaw (KB/2/A/2018).

Background. The aim of our study was to describe the selected parameters of diffusion-weighted imaging (DWI) and perfusion dynamic contrast enhancement (DCE) MRI in primary tumors in patients with serous epithelial ovarian cancer (EOC), as well as in disease course prognosis and treatment response, including bevacizumab maintenance therapy. Materials and Methods. In total, 55 patients with primary serous EOC were enrolled in the study. All patients underwent MR imaging using a 1.5 T clinical whole-body MR system in preoperative DWI and DCE MRI selected parameters: apparent diffusion coefficients (ADC), time to peek (TTP) and perfusion maximum enhancement (Perf. Max. En.) were measured. The data were compared with histopathological and immunochemistry results (with Ki67 and VEGF expression) and clinical outcomes. Results. Higher mean ADC values were found in low-grade EOC compared to high-grade EOC: 1151.27 vs. 894,918 (p < 0.0001). A negative correlation was found between ADC and Ki67 expression (p = 0.027), and between ADC and VEGF expression (p = 0.042). There was a negative correlation between TTP and PFS (p = 0.0019) and Perf. Max. En. and PSF (p = 0.003). In the Kaplan−Meier analysis (log rank), a longer PFS was found in patients with ADC values greater than the median; p = 0.046. The Kaplan−Meier analysis showed a longer PFS (p = 0.0126) in a group with TTP below the mean value for this parameter in patients who received maintenance treatment with bevacizumab. Conclusions. The described relationships between PFS and DCE and DWI allow us to hope to include these parameters in the group of EOC prognostic factors. This aspect seems to be of particular interest in the case of the association of PFS with DCE values in the group of patients treated with bevacizumab.
RESUMEN
BACKGROUND: The aim of this pilot study was to evaluate the value of imaging techniques, including computed tomography (CT) and magnetic resonance imaging (MRI), in the diagnosis of a tumor-bowel fistula as a rare form of epithelial ovarian cancer (EOC) relapse. We also performed an initial assessment of the effectiveness of the treatment of this form of relapse. METHODS: The study group consisted of eight patients with suspected platinum-sensitive recurrence in the form of a tumor/bowel fistula. All patients finished their first line of chemotherapy and subsequently showed complete remission for 6 months or more. To qualify patients for further treatment, CT and MRI were performed, which suggested the presence of a fistula between the recurrent tumor and intestine. DESKTOP study criteria were used to qualify patients for secondary cytoreduction. Second-line chemotherapy was given after secondary debulking. RESULTS: In all patients, fistulas formed between the tumor and large bowel. On CT, the fistulas were indirectly visible. In all cases, the fistula was visible on MR images, which showed hypointensity on the T2 and T1 post-contrast sequences but did not show restricted diffusion on the diffusion-weighted imaging (DWI) sequence. Patients who were qualified for the study underwent secondary debulking with bowel resection. In all eight cases, the fistula between the tumor and surrounding organs was confirmed. During surgery, seven intestinal anastomoses and one colostomy were performed. No residual macroscopic tumor remained in seven cases (resection R0-87.5%). The progression-free survival (PFS) was 8.4-22.6 months (median 13.4). In the group with cytoreduction R0, the median PFS was 15.5 months (12-22). CONCLUSION: In patients with suspected EOC recurrence with clinically suspected fistula, CT scan is not sufficient. In CT, the presence of a fistula is suspected based on indirect symptoms. MRI, as a method with much greater tissue resolution, confirms the diagnosis. In addition, MRI can identify the point of the tumor/bowel junction. This is especially true with a large infiltration covering several intestinal parts. Bowel resection with simultaneous anastomosis is a good and safe solution for these patients. However, appropriate qualification for the procedure is necessary, which will allow for surgery without residual macroscopic disease (R0 surgery). Due to the small number of cases, our results cannot be generalized. We treat them as a hypothesis that can be verified in a larger study.

Vulvar intraepithelial lesions are a heterogenic group of diseases, which can be easily misdiagnosed. The case of a 61-year-old woman with a history of genital intraepithelial lesions and infection with HPV is presented. Her main complaint was vulvar pruritus. Vulvoscopy revealed the presence of two skin lesions: the first one had the morphology of lichen sclerosus, and the second of a Bowenoid lesion. The biopsy of the first lesion revealed vulvar intraepithelial neoplasia, whereas cells of squamous vulvar cancer were identified in the second lesion. After staging, the patient was advised to undergo hemivulvectomy and lymphadenectomy. The coexistence of morphologically diverse vulvar skin lesions may cause difficulties with diagnosis and the selection of an adequate treatment. Long-term follow-up and regular examination are essential for diagnosis of vulvar malignancies in the early stage.
RESUMEN
Ganglioneuroma is a rare tumour originating from neural crest cells, occurring mainly within children older than 7 years. It can be localised in pelvic; however, this localisation is extremely rare. This paper presents the case of a 39-year-old woman, at whom the pelvic localisation of the lesion and the unspecific symptoms associated with the digestive and genital tract impeded the recognition of the actual disease. The immensely slow growth of the tumour, combined with gradual fading of the symptoms, indicated its benign character. Only the CT-controlled biopsy enabled the recognition of the ganglioneuroma. Taking under consideration the histopathologic result and the cease of the symptoms, we decided to leave the patient under observation. After 6 years of observation, no progression signs have been recorded.
RESUMEN
OBJECTIVES: One of the common symptoms in patients with advanced gynecologic tumors is intestinal obstruction. Palliativemanagement may include pharmacological treatment, stenting as well as surgical removal of obstruction cause.Selection of appropriate treatment should be based on careful and individual assessment of advantages, disadvantagesand possible complications. The aim of the study was to analyze the effectiveness of non-invasive treatment in patientswith gynecologic malignancies suffering from intestinal obstruction. MATERIAL AND METHODS: It was a retrospective analysis of factors associated with primary non-invasive intestinal obstructiontreatment effectiveness. Data were collected from medical records of 17 patients managed and followed-up in a singlegynecologic oncology center due to endometrial cancer, fallopian tube cancer, uterine leiomyosarcoma, and ovarian canceradmitted to the ward because of symptomatic intestinal obstruction. Mean observation time lasted 40.6 months. Non-invasivetreatment included fluid therapy, dexamethasone, buscolysin, mebeverine, ranitidine, simethicone, omeprazole,magnesium sulphate, semi-liquid diet, and parenteral nutrition. Characteristics including age, BMI, comorbidities, oncologicaltreatment, histology type, stage, grade, presence of ascites, location of primary tumor and metastases were analyzed. RESULTS: The number of obstruction episodes varied from 1 to 5. Mean time between multiple episodes lasted 3.2 months. 5 patientsrequired surgical treatment. For the rest of the patients primary non-invasive treatment was sufficient. CONCLUSIONS: Most cases of bowel obstruction in patients with advanced gynecologic malignancies can be successfullymanaged without invasive treatment. Moreover, non-invasive obstruction management can be applied multiple times incase of recurrence.

Plasminogen activator inhibitor type 1 (PAI-1) belongs to the family of the plasminogen activator system. PAI-1 stimulates fibrinolysis and also promotes tumor progression. The aim of this study was to evaluate the prognostic value of blood plasma PAI-1 content in patients with epithelial ovarian cancer who start the first-line chemotherapy. PAI-1 content was measured in the blood of 61 patients with epithelial ovarian cancer at onset of first-line chemotherapy. The patients were further stratified into the low PAI-1 group (≤20 ng/mL; 33 patients) and the high PAI-1 group (>20 ng/mL; 28 patients). We found that the greater plasma PAI-1 content was associated with a significantly lower probability of a 5-year-long survival compared to that when PAI-I content was lower (45.5% vs. 69.5%, respectively; p = 0.04). However, the risk of cancer recurrence within 5 years failed to differ appreciably. A multivariate analysis revealed that the lower PAI-1 plasma content was an independent factor of longer overall survival (death risk ratio of 0.36, 95%CI = 0.16-0.79; p < 0.01). We conclude that PAI-1 is yet another biomarker of survival in patients with ovarian cancer.

PURPOSE: Primary fallopian tube carcinoma (PFTC) is the rarest form of female genital malignancy. The imaging applied for suspected adnexal masses includes transvaginal ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI), but the vast majority of PFTC is recognised intraoperatively. MATERIAL AND METHODS: The study group consisted of seven women with postoperatively histopathological diagnosis of PFTC. To recognise characteristic findings for PFTC, retrospective analysis of preoperative MRI was performed. All patients underwent MRI of the pelvis and abdomen using a 1.5T MR system. Based on the results of the above imaging, suspected adnexal masses were recognised. MRI protocol contained T2-weighted images, fat-suppressed T2-weighted, T2-TIRM, DW EPI, pre- and postcontrast dynamic 3D T1 GRE in transverse orientation, with diffusion weightings of 0, 50, 100, 150, 200, 400, 800, and 1200 s/mm2. Regions of interest were outlined by a radiologist, who documented the character of adnexal masses on diffusion-weighted (DW) images and apparent diffusion coefficient (ADC) maps. RESULTS: In all seven patients with PFTC unilateral tumour was found. On all DW images (with ß values of 0, 50, 100, 150, 200, 400, 800, and 1200 s/mm2) the mean signal intensities of solid parts of tumour were significantly higher than the mean signal intensities of normal ovarian tissue (p = 0.0001). There were no statistically significant differences between eight ß values applied for ADC calculations. CONCLUSIONS: Preoperative diagnostics of PFTC is difficult and mainly based on morphological features. Previous research did not show characteristics of PFTC in post-contrast dynamic imaging. In our material a clear increasing of signal intensity in DW imaging occurred independently of the ß value.

INTRODUCTION: MRI is established modality for the diagnosis of ovarian malignancies. Advances in MRI technology, including DW imaging, could lead to the further increase in the sensitivity of MRI for the detection of peritoneal metastases. The aim of this study was to assess the accuracy of DW imaging for detection of peritoneal metastatic disease in patients suspected of having potentially early ovarian cancer and secondly to evaluate ADC values of peritoneal implants. MATERIALS AND METHODS: The prospective study group consisted of 26 women with sonographic or/and CT diagnosis of suspected ovarian tumor. Based on the results of the above imaging, in none of them was extraovarian spread of disease or ascites recognized. All patients underwent MRI with DW imaging. RESULTS: Overall, 18 extraovarian peritoneal lesions were found on DW images in 10 from 26 examined patients. All implants had diameter ≤10 mm. The presence of all lesions diagnosed by MRI was confirmed intraoperatively. Histopathologic findings in 17 proofs confirmed ovarian cancer. PPV was 94%. On all DW images (with b values of 0, 50, 100, 150, 200, 400, 800, and 1200 s/mm(2)) the mean signal intensities of peritoneal lesions were significantly higher than the mean signal intensities of normal adjacent tissue (p = 0.000001).

BACKGROUND: The surgical treatment of patients with advanced-stage ovarian cancer is based on maximal cytoreduction with widening the debulking on the extra-ovarian tissues and infiltrated organs. The purpose of the study was to assess the outcome after optimal cytoreduction with partial bowel resection and to find the risk factors of relapse. Another goal was the quantitative and qualitative assessment of intra- and postoperative complications in the studied group. METHODS: The analysis of debulking procedures with intestinal resection and postoperative period in 33 ovarian cancer patients, The International Federation of Gynecology and Obstetrics (FIGO) stages III and IV, was performed. RESULTS: The optimal cytoreduction defined as less than 1.0 cm residual disease was achieved in all patients including the following: 26 patients (78.8%) with no macroscopic residual disease, 4 patients (12.1%) with the largest residual tumor less than 0.5, and 3 patients (9.1%) with 0.5 cm to less than 1.0 cm residual disease. The rectosigmoid resection was the most common surgical procedure (n = 27). The risk of relapse was significantly higher in subjects who had the macroscopic residual tumor left during the primary operation (57.1 vs. 11.5%, P = 0.035). A primary bowel tumor size was another predictor of relapse. The maximum tumor diameter was significantly larger (14.9 ± 6.7 cm vs. 10.3 ± 4.7 cm, P = 0.047) in patients who developed the relapse. CONCLUSIONS: As presented in the article, our outcomes and other authors' observations indicate that debulking surgery with bowel resection in patients with advanced ovarian cancer brings good results. Complications connected with bowel surgery are to be accepted. The interesting thing is that a primary bowel tumor size was a predictor of relapse.

OBJECTIVES: The aim of the study was the assessment of perioperative complications in patients with advanced ovarian cancer who underwent splenectomy to achieve optimal debulking. MATERIAL AND METHODS: We analyzed eight debulking procedures with splenectomy and the postoperative period in ovarian cancer patients, FIGO stage III/B-IV. Preoperative diagnostics included multidetector computed tomography (MDCT) or diffusion-weighted echo-planar magnetic resonance (MR-DWI). The following factors were analyzed: size of the removed tumor, size of remains left, blood loss, packed red blood cell transfusion, quantity and reason for reoperations, pancreatic amylase concentrations in the drainage fluid, wound infection, fever over 38 degrees C, and length of hospitalization. RESULTS: Complete debulking was achieved in 8 patients, including 5 cases with no macroscopic residual lesions and 3 patients with lesion diameter of < 10 mm. Median operative time was 175 min. There was one case of reoperation caused by perforation of the stomach wall (histologically confirmed stress ulcer). Median blood loss was 1050 ml and the rate of packed red blood cells transfusion was 75%. Elevated amylase levels in the drainage fluid was noted in 6 patients. Amylase concentration was greater than 5 times the normal serum value during the first postoperative day. After postoperative day 3 it was lower than normal serum range. There were no cases of postoperative fever wound infections, or deaths. The length of hospitalization was 6 days. CONCLUSIONS: Splenectomy as a part of cytoreductive surgery for advanced ovarian cancer may contribute to achieving complete debulking and bring benefits, especially in cases with no macroscopic residual disease. The risk of intra- and postoperative complications related to splenectomy seems to be acceptable.

OBJECTIVE: The aim of this study was to evaluate the feasibility of multi-detector row computed tomography (MDCT) in the differentiation between borderline ovarian tumors and ovarian cancer on the basis of tumor morphology and specific features of tumor vascularity in correlation with the results at pathology. METHODS: A triphasic MDCT protocol was used for the analysis of tumor vascularity. The following features were taken into account: (1) The number of vessels in papillary projections, solid-tissue component, and septa (2 vs >2), (2) serpentine and chaotic configuration of vessels, (3) presence of microaneurysms, and (4) presence of arteriovenous microfistulas. Masses with at least 3 of 4 features were considered ovarian cancer (group A) and masses with 2 features or less as borderline tumor (group B). Radiological findings were compared with results of postoperative pathology. RESULTS: Pathologic vessels were found in all 56 patients. Thirty-two patients were included in group A and 24 in group B. The results of pathology were as follows: in group A: 31 malignant tumors, including 31 ovarian carcinomas and 1 benign cystadenoma; in group B: 22 borderline ovarian tumors, 1 benign cystadenoma, and 1 ovarian cancer. CONCLUSIONS: Morphological evaluation of tumor vascularity in MDCT seems to be an efficient method of differentiating between borderline ovarian tumors and ovarian carcinomas. Because of a small number of cases in the current study, a further research seems justified to confirm our results. The presented MDCT-angiographic criteria showed high sensitivity (97%) and specificity (96%) in differentiation of borderline ovarian tumors and ovarian cancers as compared with pathology. The presented CT-angiographic criteria of malignancy showed an excellent interobserver agreement.

BACKGROUND: PALB2 protein was recently identified as a partner of BRCA1 and BRCA2 which determines their proper function in DNA repair. METHODS: Initially, the entire coding sequence of the PALB2 gene with exon/intron boundaries was evaluated by the PCR-SSCP and direct sequencing methods on 70 ovarian carcinomas. Sequence variants of interest were further studied on enlarged groups of ovarian carcinomas (total 339 non-consecutive ovarian carcinomas), blood samples from 334 consecutive sporadic and 648 consecutive familial breast cancer patients, and 1310 healthy controls from central Poland. RESULTS: Ten types of sequence variants were detected, and among them four novel polymorphisms: c.2996+58T>C in intron 9; c.505C>A (p.L169I), c.618T>G (p.L206L), both in exon 4; and c.2135C>T (A712V) in exon 5 of the PALB2 gene. Another two polymorphisms, c.212-58A>C and c.2014G>C (E672Q) were always detected together, both in cancer (7.5% of patients) and control samples (4.9% of controls, p = 0.2). A novel germline truncating mutation, c.509_510delGA (p.R170fs) was found in exon 4: in 2 of 339 (0.6%) unrelated ovarian cancer patients, in 4 of 648 (0.6%) unrelated familial breast cancer patients, and in 1 of 1310 controls (0.08%, p = 0.1, p = 0.044, respectively). One ovarian cancer patient with the PALB2 mutation had also a germline nonsense mutation of the BRCA2 gene. CONCLUSIONS: The c.509_510delGA is a novel PALB2 mutation that increases the risk of familial breast cancer. Occurrence of the same PALB2 alteration in seven unrelated women suggests that c.509_510delGA (p.R170fs) is a recurrent mutation for Polish population.

INTRODUCTION: The goal of this retrospective analysis was to compare the results of treatment in patients with early cervical cancer managed by laparoscopy with those for patients observed after laparotomy. METHODS: The retrospective analysis was carried out with 22 patients operated on with total laparoscopic hysterectomy and 58 patients treated by abdominal hysterectomy. Patients with clinical tumor stage IA, IB1, or IIA were eligible for surgery. The main efficacy end point was disease-free survival evaluated by the Kaplan-Meier method. The survival curves were compared using log-rank tests. In addition, length of hospitalization, duration of surgery, and complication rate were compared. P < 0.05 was set as statistically significant. RESULTS: Predicted 3-year disease-free survival rates in the "open surgery" and "laparoscopy" groups were 0.86 (standard deviation [SD], 0.049) and 0.82 (SD, 0.098), respectively (P = 0.53). Recurrence rate was 13.6% after laparoscopy and 12% in open surgery. In 2 patients, intraperitoneal spread occurred after laparoscopy. The operation time was longer and hospitalization shorter after laparoscopy. CONCLUSIONS: The 3-year disease-free survival was similar in both groups. Total laparoscopic radical hysterectomy may be an option in early cervical cancer; however, the intraperitoneal spread in 2 patients compels a search for possible risk factors in patients managed by laparoscopy.

INTRODUCTION: The risk of endometrial cancer recurrence is estimated to be about 20%. In most cases, such situations are recognized in the first 3 years after the primary treatment. Early detection of such episodes leads to effective treatment. The aim of this study was to evaluate some histoclinical factors in the risk of recurrence. MATERIAL AND METHODS: Between the year 2001 and 2003, 203 from 243 patients with endometrial cancer underwent surgery. All procedures were performed in accordance with surgical-pathological staging system. The following histoclinical factors were taken into account: age, number of deliveries, BMI, use of estrogens, co-morbidity, histoclinical type, grading and the spread of cancer inside the uterus, pelvis and retroperitoneal space. RESULTS: 29 recurrences (14.3%) were found in all analyzed groups. The mean time of follow-up was 43 months. The mean time of recurrences was 16 months (9-51 months). Lymph node metastases were recognized in 28 patients (13.7%). The most important factors in the multivariate analysis were: type of histology (serous or clear cell cancer) and lymph node involvement. Recognizing 2 or more metastatic lymph nodes significantly increased the risk of recurrences. CONCLUSION: In patients with endometrial cancer the risk of recurrences increases when lymph node metastases are recognized. This risk is 5 times higher when 2 or more lymph nodes are involved, comparing with patients with one node metastasis. Four times higher recurrence risk is observed in serous or clear cell cancer, comparing with other histological types.

OBJECTIVES: (1) Evaluation of the influence of hemostatic disorders on renal function in patients with FIGO stage IIB-IIIB cervical cancer treated with radiochemotherapy. (2) Identifying methods of improving renal function in this patients group. METHODS: Treatment design assumes the administration of a total radiation dose of 46-65 Gy and, additionally, cisplatin 40 mg/m2 every 7 days in patients with normal plasma creatinine level. Renal function was assessed with the aid of dynamic scintigraphy with glomerular filtration rate (GFR) evaluation. Analysis of serum hemostatic system covered D-dimers, PAP, PAI-1, tPA, FDP, F1+2 and TAT. The same hemostatic parameters were also evaluated in urine. The patients were divided into two groups: the study group - i.e. patients with affected GFR and the control group - with normal GFR. Half of study group patients, throughout the entire treatment, receive nadroparine 2850 units aXa/0.3 ml every 24 h during and 6 weeks after the treatment. RESULTS: There are significant decreases of GFR in control (median -9.7%) and study group without nadroparine (median -9.9%) and increase in the GFR (median 22.3%) in study group with nadroparine (p=0.0001). Plasma and urine hemostatic parameter analysis showed activation of fibrinolysis in patients treated with nadroparine and fibrinolysis inhibition in remaining groups. CONCLUSIONS: (1) Inhibition of fibrinolysis may cause subclinical renal insufficiency in patients with advanced cervical cancer. (2) Insufficiency increases after the end of radiochemotherapy in patients, as well with normal GFR as, with primary decreased GFR. (3) Application of nadroparine causes fibrinolysis activation, and increase in the GFR.

BACKGROUND: Massive bleeding from an exophytic tumor is a serious complication in advanced cases of cervical carcinoma. With persistent bleeding the embolization or ligation of an artery is required. CASE: This report describes the technique of laparoscopic ligation of the hypogastric artery in patients with massive bleeding in advanced cases of cervical cancer (FIGO Stage III). Laparoscopy was performed before or at the beginning of radiation therapy. Three cases are presented. CONCLUSIONS: Laparoscopic ligature of the hypogastric artery can replace laparotomy in patients with advanced cervical cancer and persistent bleeding. The laparoscopic procedure is less traumatic than laparotomy and enables the continuation of external radiotherapy without delay.
