Rak tijela maternice, prema zadnjim podatcima Registra za rak iz 2017. godine u Republici Hrvatskoj, nalazi se na četvrtom mjestu po učestalosti, a na osmom mjestu po smrtnosti. Najčešće se ...dijagnosticira u postmenopauzalnih žena, većinom u dobi od 50. do 79. godine života. Dijagnoza karcinoma endometrija utvrđuje se patohistološkom analizom kiretmana ili bioptata sluznice maternice, a stupanj proširenosti bolesti primjenom slikovnih metoda. U većine bolesnica bolest se otkriva u lokaliziranom stadiju te se uspješno liječi operativno, a ovisno o patohistološkom nalazu i primjenom odgovarajuće adjuvantne terapije. Lokalno uznapredovala bolest najčešće se liječi operativno uz adjuvantnu terapiju, a metastatska primjenom kemoterapije ili hormonske terapije. Mezenhimalni tumori tijela maternice liječe se operativno uz dodatak sistemske terapije adjuvantno ili samo sistemskom terapijom u slučaju diseminirane bolesti. Ove kliničke upute pisane su u cilju postizanja najviših standarda i ujednačenja postupaka u dijagnosticiranju, liječenju i praćenju bolesnica sa zloćudnim tumorima tijela maternice u Republici Hrvatskoj.
Rak vrata maternice, u odnosu na novotvorine drugih ginekoloških sijela, bolest je žena mlađe životne dobi koja se može prevenirati zdravstvenim odgojem i cijepljenjem adolescentske populacije te ...preventivnim i redovitim ginekološkim pregledima, a u ranim stadijima bolesti i učinkovito liječiti. Metode liječenja uključuju kirurgiju, radioterapiju i sistemnu terapiju, ovisno o stadiju bolesti i općem stanju bolesnica. Odluku o liječenju donosi multidisciplinarni tim u koji trebaju biti uključeni ginekolozi, radiolozi, klinički onkolozi, patolozi, citolozi i po potrebi kirurzi i urolozi. Uspjeh liječenja uvelike ovisi o njihovoj međusobnoj suradnji i kvalitetnoj komunikaciji u razmjeni iskustava i nalaza. S obzirom na važnost ove bolesti i posljedice koje ostavlja na obitelj i društvo potrebno je definirati i provoditi standardizirani pristup u dijagnostici, liječenju i praćenju ovih bolesnica. U tekstu koji slijedi iznesene su obnovljene i nadopunjene kliničke smjernice s ciljem implementacije standardiziranih postupaka u radu s bolesnicama s rakom vrata maternice u Republici Hrvatskoj.
The 43rd European Congress of Cytology in Wrocław, Poland, was held as a hybrid meeting in the Fall of 2021. After nearly 2 years without in‐person cytology conferences, the 43rd Congress represents ...1 of the first major international scientific meetings to occur during the severe acute respiratory syndrome‐coronavirus 2 pandemic. Since March 2020, the pandemic situation substantially modified the organization of scientific meetings because of both domestic and international travel restrictions, new health standards, and concern among participants, resulting in new alternative forms of virtual conferencing.

Background
High‐risk human papilloma virus (HR HPV) testing and liquid‐based cytology are used for primary cervical screening. Digital cytology, based on whole‐slide scanned samples, is a promising ...technique for teaching and diagnostic purposes. The aim of our study was to evaluate the interobserver and intraobserver variation in low‐grade squamous lesions, HR HPV status bias, and the use of whole‐slide scanned digital cervical cytology slides.
Methods
Fifteen expert cytopathologists evaluated 71 digitalized ThinPrep slides (31 atypical squamous cells of undetermined significance ASC‐US, 21 negative for intraepithelial lesion or malignancy, and 19 low‐grade squamous intraepithelial lesion cases). HR HPV data were accessible only in the second round.
Results
In interobserver analysis, Kendall’s coefficient of concordance was 0.52 in the first round and 0.58 in the second round. Fleiss’ kappa values were 0.29 in the first round and 0.31 in the second round. In the ASC‐US category, Fleiss kappa increased from 0.19 to 0.22 in the second round and the increase was even higher expressed by Kendall’s coefficient: from 0.42 to 0.52. In intraobserver analysis, personal scores were higher in the second round.
Conclusions
The interobserver and intraobserver variability in low‐grade squamous lesions was within fair agreement values in the present study, in line with previous works. The comparison of two rounds showed that expert cytopathologists are generally unbiased by the knowledge of HR HPV data, but that being informed of the HR HPV status leads to a better agreement. Stain quality and back discomfort were highlighted as factors affecting digital cytopathology use.
The interobserver and intraobserver variability in low‐grade squamous lesions was within fair agreement values and knowing high‐risk human papillomavirus status leads to better agreement. Stain quality and back discomfort were highlighted as factors affecting digital cytopathology use.
The majority of endometrial carcinoma are diagnosed at an early stage and exhibit a favorable prognosis. However, 10% to 15% of ECs recur and the majority are type II tumors which are high-grade ...carcinomas. The epithelial-mesenchymal transition (EMT) has been considered as a fundamental step for the development of the invasive phenotype of cancer cells. During EMT, many of epithelial surface markers, primarily E-cadherin disappear, and mesenchymal markers including N-cadherin gain. This feature resides predominantly at the invasive front (IF) of the tumor. Therefore, we examined the immunohistochemical expression of E-cadherin and N-cadherin at the IF, in central areas of the tumor and lymphovascular space, in type I and type II endometrial carcinoma. The association of each protein with the clinicopathologic features was also evaluated. Our results confirmed a stronger E-cadherin immunostaining in type I tumors indicating that the loss of E-cadherin may be responsible for a more aggressive behavior of type II ECs. In both types, E-cadherin was strongly expressed in central areas and the reactivity decreased toward the IF. On contrary, N-cadherin was overexpressed at the IF confirming an inverse relationship between these markers. In addition, a decrease in E-cadherin expression was observed in cells within the lymphovascular space. Downregulation of E-cadherin was associated only with high-grade tumors while no correlations between both markers and other clinicopathologic features were found. Our results confirm that EMT occurs at the IF that represents a critical interface between the tumor and the host.
Objective: The aim of the study was to evaluate the accuracy of the diagnostic Pap test (DPT) on three slides and punch biopsy and endocervical curettage (PB/ECC) compared with the final biopsy ...material in the detection of high-grade squamous intraepithelial lesion (HSIL). Materials and methods: Patients treated with conization after previous DPT and PB/ECC were analyzed. The findings of the DPT and PB/ECC as well as of the endocervical brush cytology and ECC were compared with the final conus histology. Results: 150 patients were analyzed, and final histology verified 145 cases of HSIL and 3 cancers. The percentage of confirmed HSIL cytology was 97%, while for PB/ECC it was 79% with 30/145 false negative results. The correlation between Pap test and PB/ECC showed that the diagnostic accuracy of DPT is significantly higher (p < 0.0001). Endocervical brush cytology confirmed HSIL+ in the endocervical canal in 83% and ECC in 35% of cases (p < 0.0001). Conclusion: The DPT on three slides enables better detection of HSIL compared to PB/ECC, particularly for lesions localized in the endocervical canal sampled with a cytobrush. A high quality DPT could represent a surrogate for PB/ECC and open the possibility of direct access to therapeutic procedure.
Cilj istraživanja je bio utvrditi utjecaj pandemije COVID-19 na sveukupni rad patohistološkog i citološkog laboratorija u KBC-u Rijeka kao i na dijagnostiku nekih od najčešćih malignih bolesti.
...Retrospektivno su iz računalne baze podataka izvučeni i međusobno uspoređeni brojevi patohistoloških i citoloških nalaza, novodijagnosticiranih malignoma dojke, pluća, debelog crijeva, endometrija i prostate te molekularnih testova za analizu mutacije EGFR i HPV-infekcije za razdoblje od 1. ožujka do 30. rujna 2019. (prije pandemije) te od 1. ožujka do 30. rujna 2020. (za vrijeme pandemije COVID-19).
Ukupni broj izvršenih pretraga bio je statistički značajno manji za vrijeme pandemije COVID-19 u 2020. u odnosu na isto razdoblje 2019. (p<0,000), patohistološke dijagnostike za 24%, neginekoloških citoloških nalaza za 20%, ginekoloških za 13% te papa testova za 11% manje. Za vrijeme COVID-19 u odnosu na isto razdoblje prije pandemije broj novodijagnosticiranih malignih tumora značajno je smanjen za maligne novotvorine debelog crijeva (–25%, p<0,0001). Smanjenje novih slučajeva karcinoma dojke (–3%) i karcinoma prostate (–4%) bilo je manje izraženo, dok je povećanje evidentirano za karcinome pluća (+2%) i endometrija (+53%). Broj HPV-testova značajno je pao za vrijeme pandemije COVID-19, za 40% (p<0,0001).
Ovim radom smo potvrdili očekivano značajno smanjenje opsega rada tijekom prvog vala pandemije COVID-19 u 2020., i to od 11% do 40%, iako broj bolesnica/ka s novodijagnosticiranim karcinomima, osim s karcinomom debelog crijeva, nije značajno pao. Važno bi bilo formirati zajednički nacionalni registar koji bi prikupio ne samo dijagnostičke, već i terapijske postupke, posebno onkoloških bolesnica/ka, čime bi se dobio objektivniji uvid u probleme zdravstvenog sustava za vrijeme pandemije. Ovi podatci mogu poslužiti promišljanju mjera i strategije za što adekvatnije zbrinjavanje ne samo oboljelih od COVID-19, već i ostalih.
Villoglandular papillary adenocarcinoma (VGA) of cervix is an uncommon but well recognized histologic subtype of cervical adenocarcinoma which usually affects young women. Based on the favorable ...outcomes reported in most previous cases the tumor is generally considered to have an indolent clinical course with excellent prognosis. We present a case of a 22-year-old woman admitted at our Department for glandular abnormality on cervical smear and episodes of vaginal discharge. In the Pap smear, the cytological features were suspicious but not diagnostic of adenocarcinoma, therefore reported as atypical glandular cells (AGC). Histological examination confirmed VGA associated with lymphovascular space invasion. The patient underwent radical operative procedure. Intraoperative cytologic examination detected pelvic lymph nodes metastasis. The patient was confirmed to be in an advanced stage - III B (FIGO). During a two years follow-up period a rapid dissemination of the tumor occurred and resulted with a fatal outcome. Although VGA has been reported to have a favorable prognosis, several cases with lymph node involvement have already been described. Cervical smears examination would be helpful for an early diagnosis of VGA, however the cytologic recognition is often difficult. Further investigation of the pathogenesis, diagnosis and therapy of the tumor is needed.
The cancer stem cells (CSCs) represent a minority of tumor cells that are able to proliferate and self-renew and might be responsible for tumor initiation and maintenance. The CD133 and CD117 are the ...most commonly used markers for the putative CSCs, especially for the ovarian CSCs, but its clinical significance remains uncertain. The aim of this study was to compare the immunohistochemical expression of CD133 and CD117 in 64 primary ovarian high grade serous carcinoma and peritoneal metastasis, and to examine their potential clinical role. CD133 expression was mainly seen in the apical/endoluminal cell surface of tumor cells and was found in 61% of the carcinoma samples and 41% of the metastasis. The median of CD133 positive cells in tumors was 1 (0.1-7)%, and in metastases was 0.6 (0.1-6)%. CD117 expression appeared as a cytoplasmic and/or membranous stain and was found in 81% of the carcinoma samples and 77% of the metastasis. The median of CD117 positive cells in tumors was 1 (0.1-8)%, and in metastases was 0.1 (0.1-7)%. Multivariate analysis has shown that patients with high CD133 expression in tumor cells have significantly shorter disease free survival and overall survival (p=0.025 and p=0.014, respectively). Patients with high CD117 expression in tumor cells have significantly shorter disease free survival (p=0.031). Cox's proportional hazards model identified expression of CD133 protein in tumor as an independent prognostic factor. Our study indicates that the immunohistochemical assessment of CD133 and CD117 expression may have potential clinical value in predicting disease progression and prognosis in the high grade serous ovarian cancer. CD133 proved to be an independent prognostic factor in the high grade serous ovarian cancer patients.
Objective. Adult granulosa cell tumors (AGCTs) represent 2%–5% of all ovarian malignancies. The aim of this study was to analyze clinical and pathohistological parameters and their impact on ...recurrence, overall, and disease-free survival in FIGO stage I AGCT patients. Methods. The tumor specimens analyzed in this retrospective study were obtained from a total of 36 patients with diagnosis of ovarian AGCT surgically treated at the Department of Gynecology, Rijeka University Hospital Centre, between 1994 and 2012. Clinical, pathological, and follow-up data were collected. Results. The mean age at diagnosis was 54.5 years with a range of 24–84. The majority of the patients, 30 (83%), were in FIGO stage IA, 3 (8%) in stage IC1, 1 (3%) in stage IC2, and 2 (6%) in stage IC3. During follow-up period (median 117.5 months, range 26–276), recurrence occurred in 4 patients (12%) with 2 deaths of the disease recorded. In univariate analysis, the 5-year survival rates were significantly shorter in patients with FIGO substage IC (p=0.019), with positive LVSI (p=0.022), with presence of necrosis (p=0.040), and with hemorrhage (p=0.017). In univariate analysis, the 5-year disease-free survival rates were significantly shorter in patients treated with fertility surgery (p=0.004), with diffuse growth pattern (p=0.012), with moderate and severe nuclear atypia (p=0.032), and with presence of hemorrhage (p=0.022). FIGO substage IC proved to be independent predictor for recurrence (OR = 16.87, p=0.015, and OR = 23.49, p=0.023, resp.) and disease-free survival (p=0.0002; HR 20.84, p=0.02) at the uni- and multivariate analyses. Conclusions. FIGO substage IC is predictive of recurrence and disease-free survival in patients with early-stage AGCTs. LVSI, presence of necrosis and hemorrhage, diffuse growth pattern, and nuclear atypia in AGCTs seem to be associated with overall and disease-free survival, so these pathological features should be taken into consideration when managing patients with AGCT.
