Abstract
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.

Abstract
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.

Abstract
Cervical cancer, in comparison with other gynecological malignancies, mainly affects younger women. It can be prevented trough educational programs, screening and early detection. It also can be efficiently treated when it appears. Treatment modalities include surgery, chemotherapy and radiotherapy, according to the stage of the disease and patient condition. Treatment decisions should be made after multidisciplinary team discussion. Due to the significance of this disease it is important to define and implement standardized approach for diagnostic, treatment and monitoring algorithm as well. The following text presents the clinical guidelines in order to standardize the procedures and criteria for the diagnosis, management, treatment and monitoring of patients with uterine cervical cancer in the Republic of Croatia.

Abstract
Cervical intraepithelial neoplasia (CIN) can be detected in the cytologic smears years before invasive squamous cancer arises, but no reproducible morphologic criteria exist to predict behavior of cervical lesions. The possibility of predicting the clinical course of cervical lesions could be of high value in clinical practice and some women will spare of unnecessary treatment. HPV L1 capsid protein represents about 90% of the total protein on the surface of the virus and can be detected in mild to moderate dysplasia and rarely in severe dysplasia. The purpose of the study was to evaluate the use of immunodetection of HPV L1 protein on archival Pap smears with findings of mild and moderate dysplasia in predicting its clinical course. Immunochemical analyses with L1 antibody revealed positively stained nuclei of squamous epithelial cells in 56 of 114 smears (49.1%). The staining results were correlated with follow-up smears or with histologic verification. Regression (negativisation of the Pap smear for 24 months or longer) was noticed in 31 of 56 (55.4%) L1-positive cases and in 20 of 58 (34.5%) L1-negative cases. Persistent disease occured in 13 (23.2%) L1-positive cases and in 14 (24.1%) L1-negative cases. Progressive disease occured in 12 (21.4%) L1-positive cases and in 24 (41.4%) L1-negative cases. The difference in the clinical course between the L1-positive and L1-negative patients was statistically significant (p = 0.025). Also, the difference in the clinical course of the L1-negative staining in the under-30 and over-30 years age group was statistically significant (p = 0.04). For conclusion, our data confirm that immunostaining for HPV L1 capsid protein could offer prognostic information about mild and moderate intraepithelial cervical squamous lesions.

Abstract
The patients treated with conservative surgical therapy for cervical intraepithelial neoplasia (CIN) have an increased risk to develop invasive cervical carcinoma compared to the general population. Cervical cytology and HPV test are included in the protocols for the detection of treatment failure. The purpose of the study was to analyse cytology-histology correlation after conisation or Large Loop Excision of the Transformation Zone (LLETZ), resection margin status, compliance to the follow-up protocol and evaluation of cervical cytology and HPV testing in two year period after surgical treatment. We retrospectively reviewed 251 cases of conisation or LLETZ performed between January and December, 2006. Conventional cervical smears were analysed and abnormal cytology was defined as atypical squamous cells of undetermined significance or worse (ASCUS+). The digene Hybrid capture 2 test was used for detection of high-risk HPV types. Histology analysis demonstrated CIN1 + lesion in 234 cases (93.2%) with cytology-histology correlation in 97.9% of cases. A preoperative HPV test was made in 142 histologically confirmed CIN1 + lesions and 137 (96.5%) tested positive. The resection margins were involved in 48 (20.8%) cases. In 24 (10.3%) cases the margins were difficult to determine. Abnormal cytology was found in 33 (15.2%) cases of the 217 (86.5%) patients that attended the post-treatment visits. The post-treatment HPV test was performed on 159 women and it was positive in 25 (15.7%) cases. The complete follow-up control cytology, with at least three Pap smears in the subsequent two years or with second treatment, was registered in only 146 (58.2%) patients. 14/217 (6.5%) patients underwent second treatment with histologically confirmed treatment failure. In all patients with control smear, repeated cytology found HSIL. On six women, the control HPV test was performed. In five cases, it was positive and in one case with histological diagnoses of VAIN2, it was negative. Our study confirms the important role of cervical cytology in the diagnosis of cervical intraepithelial lesions and monitoring after treatment. In the future we will have to improve compliance to the follow-up protocols and use of the HPV test in the selection of women at risk of treatment failure.

Abstract
The opportunistic cervical cancer screening has been conducted in Croatia since its introduction in the 1960s, in the context of a high quality gynaecological cytology with a long tradition and a wide network of primary care gynaecologists. In 2006, a pilot screening programme under the title "Early detection of cervical cancer was conducted in Primorsko-Goranska County (PGC)", as the first organised cervical cancer screening ever conducted in the Republic of Croatia. The pilot screening programme targeted women aged 20-64 years. The pilot group consisted of 6,000 randomly sampled primary care patients of six gynaecologists. The women were invited via a personal letter and were given a questionnaire. The results of the first and the second year of screening, as well as of both years together were analysed. The response rate to the anamnestic questionnaire was 49.1%. The participation rates to the screening were 35.2% in 2007, and 46.5% in 2008, total of 42.7%. The increase in participation between years 2007 and 2008 was statistically significant (p = 0.01). According to the age, the lowest participation rate of 33.3% was observed in the youngest group of women (20-29) and the highest of 60.7% in the oldest group (60-64). The detection rate of cytological abnormalities was 4.6% with 2.6% of borderline (ASCUS) cytology and referral rate of 1.2%. The highest abnormal Pap test frequencies of 6.8% and 7.1% were observed in the youngest age groups (20-29 and 30-39), and the lowest (2%) in the age group of 60-64. Specimen adequacy was generally of high quality with unsatisfactory rate of 0.8%, with statistically significant improvement in 2008, compared to the previous year (p = 0.001). Although to a limited extension, during two-year pilot cervical cancer screening programme in PGC the participation rates and Pap smear adequacy have improved. We expect that the continuation of the programme will result in further increase of participation and higher overall quality of the programme.

Abstract
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.

Abstract
OBJECTIVE To determine the morphometric characteristics of nuclei and silver-stained nucleolar organizer regions (AgNORs) on cytologic imprints and their value in differential cytodiagnosis of benign, atypical proliferative (borderline) and malignant ovarian mucinous tumors. STUDY DESIGN Forty-six mucinous ovarian tumor imprints (16 benign, 15 borderline, 15 malignant), were analyzed. Nuclear area, outline, "shape factor" and "form factor" were measured on Papanicolaou-stained smears. AgNOR quantification included 7 variables related to the number and area of single, cluster, total and relative AgNOR content per nucleus and the size distribution of AgNORs. RESULTS Nuclear area and shape factor allowed distinguishing borderline and malignant tumors. The nuclear area in benign tumors was larger than that in borderline tumors; malignant tumors had the highest values. Single and cluster AgNORs were statistically significantly different in borderline tumors compared with malignant tumors, except for the cluster AgNOR area. The total AgNOR area, number and relative area increased from benign through malignant tumors, with statistically significant differences among all groups. By AgNOR size distribution, small AgNORs discriminate malignant from borderline and benign tumors. CONCLUSION Combining nuclear morphometry and AgNOR analysis on cytologic imprints could be a diagnostically useful method in the assessment of mucinous ovarian tumors.

Abstract
Opportunistic screening based on the Pap smear has been undertaken in Croatia since 1953. However, cervical cancer remains an important health problem in Croatia when compared to European countries with organised screening programmes. In Croatia, in addition to screening based on well established cytology, Human papillomavirus (HPV) testing is widely used as secondary test as a triage to borderline cytology and as a follow-up after treatment of severe cervical lesions. Many different approaches for HPV testing arose in Croatia over the last decade depending on the needs of each medical institution involved. Presently, there is an urgent need for better networking between the laboratories, the implementation of quality assessment and the adaptation of a uniform system of referring to and reporting of HPV testing. In conclusion, the best possible organisation for HPV testing would be essential for implementation of HPV testing as primary screening test in Croatia, an thus ultimately and hopefully, the more successful cervical cancer control.

Abstract
AIM The aim of the study was to determine values of a quantitative morphometry analysis of nuclear characteristics and argyrophilic nucleolar organizer regions (AgNORs) in differential cytodiagnosis of benign, atypically proliferating (borderline) and malignant serous ovarian tumours. METHODS Cytological imprints of benign (n = 20), borderline (n = 19) and malignant (n = 20) ovarian serous tumours were analysed. A computerized, digital analysis was used to determine morphometric nuclear features, the number and characteristics of single AgNORs, cluster AgNORs, total AgNOR and AgNOR area/nucleus (relative area) ratio. According to their size AgNORs were classified in three categories. A one-way variance analysis and post hoc test (Scheffé) were used for statistical analysis. RESULTS The morphometric nuclear analysis showed that benign, borderline and malignant serous ovarian tumours are statistically different (P < 0.001) according to the area and outline, the values being highest in malignant tumours and lowest in the borderline group. Digital analysis of AgNORs in benign, borderline and malignant groups showed that the total AgNOR number increases with progression of the lesion (meaning tumour malignancy) significantly (P < 0.001) between benign and malignant as well as between borderline and malignant serous ovarian tumours (P < 0.001). The progression of the lesion malignancy was accompanied by a significant (P < 0.001) progressive increase of the total and relative AgNOR area per nucleus. The AgNOR size increases from benign to malignant tumours and a statistically significant difference (P < 0.001) was observed in all three groups regarding small and large AgNORs. CONCLUSION Combining different markers of morphometric nuclear characteristics and AgNOR values could improve differential cytodiagnosis of benign, borderline and malignant serous ovarian tumours.

Abstract
OBJECTIVE To describe the cytomorphology of clear cell carcinoma (CCC) of the ovary in intraoperative samples of peritoneal fluid, imprint and scraping samples of the tumour tissue. STUDY DESIGN Fourteen histologically confirmed cases, stained by standard cytological procedures, were analysed by light microscopy. RESULTS In 33.3% of peritoneal fluid samples and 92.9% of imprint and scraping cytological samples, besides variable clear cell cellular morphology, one or both distinct cytological characteristics were observed: eosinophilic, hyaline, extracellular, globular substance with or without formation of a 'raspberry' body and an eosinophilic, intracytoplasmic inclusions. These structures were clearly seen only in samples stained by May-Grünwald-Giemsa. CONCLUSION Using cytological analysis of imprint and scraping samples of ovarian tumours it is possible to make a precise intraoperative cytological diagnosis in most cases of CCC of the ovary.
