1. Hypodontia phenotype in patients with epithelial ovarian cancerAnita Fekonja, Andrej Čretnik, Danijel Žerdoner, Iztok Takač, 2015, original scientific article Abstract: Background. Ovarian cancer is usually diagnosed in an advanced stage and the present clinical and diagnostic molecular markers for early OC screening are insufficient. The aim of this study was to identify potential relationship between the hypodontia and epithelial ovarian cancer (EOC). Patients and methods. A retrospective study was conducted on 120 patients with EOC treated at the Department of Gynaecologic and Breast Oncology at the University Clinical Centre and 120 gynaecological healthy women (control group) of the same mean age. Women in both groups were reviewed for the presence of hypodontia and the patients with EOC also for clinicopathological characteristics of EOC according to hypodontia phenotype. Results. Hypodontia was diagnosed in 23 (19.2%) of patients with EOC and 8 (6.7%) controls (p = 0.004; odds ratio [OR] = 3.32; confidence interval [CI], 1.42-7.76). There was no statistically significant difference in patients with EOC with or without hypodontia regarding histological subtype (p = 0.220); they differed in regard to FIGO stage (p = 0.014; OR =3.26; CI, 1.23%8.64) and tumour differentiation grade (p = 0.042; OR = 3.1; CI, 1.01-9.53). Also, bilateral occurrence of EOC was more common than unilateral occurrence in women with hypodontia (p = 0.021; OR = 2.9; CI, 1.15-7.36). We also found statistically significant difference between the ovarian cancer group and control group in presence of other malignant tumours in subjects (p < 0.001). Conclusions. The results of the study suggest a statistical association between EOC and hypodontia phenotype. Hypodontia might serve as a risk factor for EOC detection.

2. Urokinase plasminogen activator (uPA) and plasminogen activator inhibitor type-1 (PAI-1) in breast cancer : correlation with traditional prognostic factorsMaja Lampelj, Darja Arko, Nina Čas-Sikošek, Rajko Kavalar, Maja Ravnik, Barbara Jezeršek Novaković, Sarah Dobnik, Nina Fokter Dovnik, Iztok Takač, 2015, original scientific article Abstract: Background. Urokinase plasminogen activator (uPA) and plasminogen activator inhibitor type-1 (PAI-1) play a key role in tumour invasion and metastasis. High levels of both proteolytic enzymes are associated with poor prognosis in breast cancer patients. The purpose of this study was to evaluate the correlation between traditional prognostic factors and uPA and PAI-1 expression in primary tumour of breast cancer patients. Patients and methods. 606 primary breast cancer patients were enrolled in the prospective study in the Department of gynaecological oncology and breast oncology at the University Medical Centre Maribor between the years 2004 and 2010. We evaluated the traditional prognostic factors (age, menopausal status, tumour size, pathohistological type, histologic grade, lymph node status, lymphovascular invasion and hormone receptor status), together with uPA and PAI-1. We used Spearman%s rank correlation, Mann Whitney U test and X2 test for statistical analysis. Results. Our findings indicate a positive correlation between uPA and tumour size (p < 0.001), grade (p < 0.001), histological type (p < 0.001), lymphovascular invasion (p = 0.01) and a negative correlation between uPA and hormone receptor status (p < 0.001). They also indicate a positive correlation between PAI-1 and tumour size (p = 0.004), grade (p < 0.001), pathohistological type (p < 0.001) and negative correlation between PAI-1 and hormone receptor status (p = 0.002). Conclusions. Our study showed a relationship between uPA and PAI-1 and traditional prognostic factors. Their role as prognostic and predictive factors remains to be further evaluated.

3. Pomen humanih virusov papiloma pri odkrivanju in preprečevanju raka materničnega vratu - kje smo danesMarjetka Uršič-Vrščaj, Sonja Bebar, Andrej Možina, Stelio Rakar, Iztok Takač, Vida Stržinar, Aleš Vakselj, 2006, published professional conference contribution Abstract: Izhodišča. S pomočjo organiziranih programov presejanja se je zmanjšala umrljivost zaradi raka materničnega vratu. Humani virusi papiloma (HPV) povzročajo predrakave spremembe in raka materničnega vratu. Številne ugotovitve kažejo, da je z vključevanjem testa HPV mogoče izboljšati uspešnost presejalnih programov. Test HPV se omenja pri presejanju, pri triažiranju bolnic z začetno patološkimi brisi materničnega vratu in po zdravljenju predrakavih sprememb. Visoka negativna napovedna vrednost dvakrat negativnega testa, testa PAP in testa HPV, naj bi na področju presejanja omogočala določene spremembe, kot so podaljševanje priporočenega rednega intervala presejanja, prilagajanje starosti ter ponovno presejanje po zdravljenju predrakavih sprememb. Test HPV je klinično pomemben pri triažiranju žensk s ponavljajočimi se atipičnimi ploščatimi celicami, pri katerih je potrebna kolposkopija. Zaradi visoke prevalence okuženosti s HPV se test HPV kaže kot omejitev pri zelo mladih ženskah z blago diskariotičnimi celicami. Zaključki. Ugotovitve o HPV nakazujejo možnosti za preprečevanje raka materničnega vratu na področju profilaktičnega cepljenja. V svetovnem merilu HPV 16 in 18 povzročata 70 % raka materničnega vratu. V prihodnjem letu naj bi bili dostopni dve profilaktični cepivi, učinkoviti proti HPV 16 in 18.
