RESUMO

Liver cirrhosis is a chronic liver disease in which the liver tissue and the vascular beds are remodeled leading to impaired hepatic function. Portal hypertension and subsequent esophageal varices are a frequent complication of liver cirrhosis and are a cause of mortality in patients with liver cirrhosis. Pregnancy in women with liver cirrhosis is uncommon, the incidence being about 1 in 5 950 pregnancies. Hepatocellular damage and the associated alteration in the metabolism of the sex hormones is thought to be responsible and leads to anovulation. In spite of all these factors, women with cirrhosis can and do become pregnant. Pregnancy is successful in most of the patients with chronic liver disease, but maternal and fetal complication rates are still high for decompensated liver cirrhosis. Portal hypertension associated with pregnancy is a high-risk situation as both pregnancy and portal hypertension share some of the hemodynamic changes. Risks of variceal bleeding and hepatic decompensation increases many fold during pregnancy. Despite the possible complications mentioned above, the maternal-fetal morbidity and mortality rates have been decreased by the current developments in hepatology, prevention of bleeding from varices with drugs and/or endoscopic variceal ligation, improvement in liver transplantation, and an increased experience in these issues. We present a case of a 31-year-old female patient with liver cirrhosis who successfully managed pregnancy and birth without complications after the insertion of transjugular intrahepatic portosystemic shunt (TIPS). Unfortunately, 2 years after delivery, the patient developed lymphoblastic lymphoma and, despite intensive therapy for this disease, the patient died at the age of 40. We did not find any link between liver cirrhosis and lymphoblastic lymphoma.

RESUMO

OBJECTIVES: To evaluate risk factors associated with the local recurrence of invasive squamous cell vulvar cancer in patient group with tumor-free pathological margins. MATERIAL AND METHODS: This is a retrospective analysis of 47 patients who underwent surgical treatment at University Hospital Brno, the Czech Republic between 2007 and 2014. 24 patients were classified as IB stage and three as II stage. A further 20 patients representing stage III showed the metastatic involvement of regional lymph nodes. Seven prognostic factors were analyzed in relation to local tumour recurrence: tumour size, margin distance, depth of invasion, lymphovascular space involvement (LVSI), midline involvement, metastatic lymph nodes and FIGO stage. RESULTS: All prognostic factors were found to be statistically significant with respect to the risk of local recurrence. The highest risk of local recurrence was observed for the depth of invasion > 5 mm (HR, 12.42 [95% CI; 3.44-44.84]) and for the presence of LVSI (HR, 10.83 [95% CI; 3.87-30.28]). The study also established a clear difference in the risk of local recurrence between patient groups with resection margin < 8 vs. ≥ 8 mm (HR, 4.91 [95% CI; 1.73-13.93; p = 0.003]. CONCLUSIONS: Tumour-free pathological margin of ≥ 8 mm is a major prognostic factor of local recurrence which can be influenced by the surgeon. A perfect knowledge of the extent of the disease prior to surgery supports adequately radical surgical trends. The emphasis is given on adequate radicality as well as on the reduction of overtreatment without worse-ning prognosis by simultaneously preserving the quality of life.

RESUMO

OBJECTIVES: To describe the ultrasound features of benign Brenner tumor in the background of complex clinical and histopathological pictures. MATERIAL AND METHODS: We retrospectively identified patients with histologically confirmed benign Brenner tumor of the ovary who were treated in our institution in 2003-2016, and for whom complete imaging, clinical, perioperative and histopathological data were available in the database. Ultrasound findings were drawn from images and reports using terms and definitions of the International Ovarian Tumor Analysis group and pattern recognition description was applied. RESULTS: Twenty-three patients were identified, most postmenopausal and asymptomatic. On ultrasound, 19/23 tumors were found unilaterally, 4/23 bilaterally, and 82% of tumors were detected in the left ovary. Most Brenner tumors (16/23) contained solid components and revealed no or minimal blood flow by subjective color score upon Doppler examination (19/23, 83%). Calcifications with shadowing were observed in 57% of all Brenner tumors and in 81% of tumors containing solid components. The complex appearance of the tumor misled the sonographers to describe the mass as malignant in 9 cases (39%), and frozen section was performed perioperatively. Surgery was performed via laparoscopy in 11 (48%) and via laparotomy in 12 (52%) cases. CONCLUSIONS: The complexity of the ultrasound picture, consisting of features like calcifications with acoustic shadowing, a poorly vascularized solid mass, and a left-sided localization could be signs of a benign Brenner tumor and could preop-eratively help to differentiate between benign and malignant tumor.

RESUMO

Background: The current model used to preoperatively stratify endometrial cancer (EC) patients into low- and high-risk groups is based on histotype, grade, and imaging method and is not optimal. Our study aims to prove whether a new model incorporating immunohistochemical markers, L1CAM, ER, PR, p53, obtained from preoperative biopsy could help refine stratification and thus the choice of adequate surgical extent and appropriate adjuvant treatment. Materials and Methods: The following data were prospectively collected from patients operated for EC from January 2016 through August 2018: age, pre- and post-operative histology, grade, lymphovascular space invasion, L1CAM, ER, PR, p53, imaging parameters obtained from ultrasound, CT chest/abdomen, final FIGO stage, and current decision model (based on histology, grade, imaging method). Results: In total, 132 patients were enrolled. The current model revealed 48% sensitivity and 89% specificity for high-risk group determination. In myometrial invasion >50%, lower levels of ER (p = 0.024), PR (0.048), and higher levels of L1CAM (p = 0.001) were observed; in cervical involvement a higher expression of L1CAM (p = 0.001), lower PR (p = 0.014); in tumors with positive LVSI, higher L1CAM (p = 0.014); in cases with positive LN, lower expression of ER/PR (p < 0.001), higher L1CAM (p = 0.002) and frequent mutation of p53 (p = 0.008). Cut-offs for determination of high-risk tumors were established: ER <78% (p = 0.001), PR <88% (p = 0.008), and L1CAM ≥4% (p < 0.001). The positive predictive values (PPV) for ER, PR, and L1CAM were 87% (60.8-96.5%), 63% (52.1-72.8%), 83% (70.5-90.8%); the negative predictive values (NPV) for each marker were as follows: 59% (54.5-63.4%), 65% (55.6-74.0%), and 77% (67.3-84.2%). Mutation of p53 revealed PPV 94% (67.4-99.1%) and NPV 61% (56.1-66.3%). When immunohistochemical markers were included into the current diagnostic model, sensitivity improved (48.4 vs. 75.8%, p < 0.001). PPV was similar for both methods, while NPV (i.e., the probability of extremely low risk in negative test cases) was improved (66 vs. 78.9%, p < 0.001). Conclusion: We proved superiority of new proposed model using immunohistochemical markers over standard clinical practice and that new proposed model increases accuracy of prognosis prediction. We propose wider implementation and validation of the proposed model.

RESUMO

AIMS: To describe the ultrasound features of benign struma ovarii that often mimic ovarian cancer in the background of complex clinical and histopathological pictures. MATERIAL AND METHODS: We retrospectively identified patients with histologically confirmed benign struma ovarii, treated in our institution between 2003-2016 with complete imaging, clinical, nd histopathological data available. Ultrasound findings were drawn from images, and reports using terms and definitions of the International Ovarian Tumor Analysis group and pattern recognition description was applied. RESULTS: In all, 19 patients were identified; 10 with pure and 9 with impure struma. Median age was 47 (range 24-69); 10 (53%) were premenopausal. Only four (21%) patients presented with pain, others were asymptomatic. Using pattern recognition, 74% strumas (14/19) were uni-/multilocular solid or solid tumors. The solid components were roundish with smooth contours. Six struma pearls were detected. The subjective color score was moderate or abundant in the majority of solid components. Only 5 (26%) tumors were purely cystic. CONCLUSIONS: The ultrasound characteristics differ widely from typical mature ovarian teratoma. Features such as, solid roundish components with smooth contours, struma pearls, acoustic shadowing and occasionally signs of dermoid are clues and may help preoperatively to differentiate benign struma from malignant adnexal lesions.
