Andraž Dovnik, Bojana Crnobrnja, Branka Žegura Andrić, Iztok Takač, Maja Pakiž, 2017, izvirni znanstveni članek

Povzetek: Background. The aim of the study was to compare the frequency of positive peritoneal washings in endometrial cancer patients after either hysteroscopy (HSC) or dilatation and curettage (D&C). Patients and methods. We performed a retrospective analysis of 227 patients who underwent either HSC (N = 144) or D&C (N = 83) and were diagnosed with endometrial carcinoma at the University Medical Centre Maribor between January 2008 and December 2014. The incidence of positive peritoneal cytology was evaluated in each group. Results. There was no overall difference in the incidence of positive peritoneal washings after HSC or D&C (HSC = 13.2%; D&C = 12.0%; p = 0.803). However, a detailed analysis of stage I disease revealed significantly higher rates of positive peritoneal washings in the HSC group (HSC = 12.8%; D&C = 3.4%; p = 0.046). Among these patients, there was no difference between both groups considering histologic type (chi-square = 0.059; p = 0.807), tumour differentiation (chi-square = 3.709; p = 0.156), the time between diagnosis and operation (t = 0.930; p = 0.357), and myometrial invasion (chi-square = 5.073; p = 0.079). Conclusions. Although the diagnostic procedure did not influence the overall incidence of positive peritoneal washings, HSC was associated with a significantly higher rate of positive peritoneal cytology in stage I endometrial carcinoma compared to D&C.

Prognostic significance of uPA/PAI-1 level, HER2 status, and traditional histologic factors for survival in node-negative breast cancer patients
Nina Fokter Dovnik, Iztok Takač, 2017, izvirni znanstveni članek

Povzetek: Background. The association of HER2 status with urokinase plasminogen activator (uPA) and plasminogen activator inhibitor 1 (PAI-1) levels raises the question whether uPA/PAI-1 level carries additional clinically relevant prognostic information independently from HER2 status. The aim of our study was to compare the prognostic value of uPA/PAI-1 level, HER2 status, and traditional prognostic factors for survival in node-negative breast cancer patients. Patients and methods. A retrospective analysis of 858 node-negative breast cancer patients treated in Maribor University Clinical Center, Slovenia, in the years 2000-2009 was performed. Data were obtained from patient medical records. The median follow-up time was 100 months. Univariate and multivariate analyses of disease-free (DFS) and overall survival (OS) were performed using the Cox regression and the Cox proportional hazards model. Results. In univariate analysis, age, tumor size, grade, lymphovascular invasion, HER2 status and UPA/PAI-1 level were associated with DFS, and age, tumor size, grade, and uPA/PAI-1 level were associated with OS. In the multivariate model, the most important determinants of DFS were age, estrogen receptor status and uPA/PAI-1 level, and the most important factors for OS were patient age and tumor grade. The HR for death from any cause in the multivariate model was 1.98 (95% CI 0.83-4.76) for patients with high uPA and/or PAI-1 compared to patients with both values low. Conclusions. uPA/PAI-1 level clearly carries an independent prognostic value regardless of HER2 status in node-negative breast cancer and could be used in addition to HER2 and other markers to guide clinical decisions in this setting.

PD-L1 expression in squamous-cell carcinoma and adenocarcinoma of the lung
Urška Janžič, Izidor Kern, Andrej Janžič, Luka Čavka, Tanja Čufer, 2017, izvirni znanstveni članek

Povzetek: With introduction of immunotherapy (IT) into the treatment of advanced non-small-cell lung cancer (NSCLC), a need for predictive biomarker became apparent. Programmed death ligand 1 (PD-L1) protein expression is most widely explored predictive marker for response to IT. We assessed PD-L1 expression in tumor cells (TC) and immune cells (IC) of squamous-cell carcinoma (SCC) and adenocarcinoma (AC) patients. We obtained 54 surgically resected tumor specimens and assessed PD-L1 expression by immunohistochemistry after staining them with antibody SP142 (Ventana, USA). Clinicopathological characteristics were acquired from the hospital registry database. Results were analyzed according to cut-off values of % 5% and % 10% of PD-L1 expression on either TC or IC. 29 (54%) samples were AC and 25 (46%) were SCC. PD-L1 expression was significantly higher in TC of SCC compared to AC at both cut-off values (52% vs. 17%, p = 0.016 and 52% vs. 14%, p = 0.007, respectively) no difference in PD-L1 expression in IC of SCC and AC was found. In AC alone, PD-L1 expression was significantly higher in IC compared to TC at both cut-off values (72% vs. 17%, p < 0.001 and 41% vs. 14%, p = 0.008, respectively), while no significant difference between IC and TC PD-L1 expression was revealed in SCC. Our results suggest a significantly higher PD-L1 expression in TC of SCC compared to AC, regardless of the cut-off value. PD-L1 expression in IC is high in both histological subtypes of NSCLC, and adds significantly to the overall positivity of AC but not SCC.

Long term results of radiotherapy in vulvar cancer patients in Slovenia between 1997-2004
Helena Barbara Zobec Logar, 2017, izvirni znanstveni članek

Povzetek: The aim of this retrospective single institution study was to analyse long term results of vulvar cancer treatment with conventional 2D radiotherapy in Slovenia between years 1997%2004. Patients and methods. Fifty-six patients, median age 74.4 years +/- 9.7 years, mainly stage T2 or T3, were included in the study. All patients were treated with radiotherapy, which was combined with surgery (group A), used as the primary treatment (group B) or at the time of relapse (group C). Chemotherapy was added in some patients. Histology, grade, lymph node status, details of surgery, radiation dose to the primary tumour, inguinofemoral and pelvic area as well as local control (LC) and survival were evaluated. Results. Overall survival (OS), disease specific survival (DSS) and LC rates at 10-years for all patients were as follows: 22.7%, 34.5% and 41.1%, respectively. The best 10-years results of the treatment were achieved in the primary operated patients treated with adjuvant radiotherapy +/-chemotherapy (OS 31.9%, DSS 40.6% and LC 47.6%). Positive lymph nodes had a strong influence on LC. In case of positive nodes LC decreased by 60% (p = 0.03) and survival decreased by 50% (p = 0.2). There was a trend to a better LC with higher doses % 54.0 Gy (p = 0.05). Conclusions. The best treatment option for patients with advanced vulvar cancer is combined treatment with surgery and radiotherapy +/- chemotherapy, if feasible. Radiotherapy with the dose of % 54.0 Gy should be considered to achieve better LC if positive adverse factors are present.

Selection of non-small cell lung cancer patients for intercalated chemotherapy and tyrosine kinase inhibitors
Matjaž Zwitter, Antonio Rossi, Massimo Di Maio, Maja Pohar Perme, Gilberto Lopes, 2017, izvirni znanstveni članek

Povzetek: Background. When treating patients with advanced non-small cell lung cancer (NSCLC) with tyrosine kinase inhibitors and chemotherapy, intercalated schedule with time separation between the two classes of drugs should avoid their mutual antagonism. In a survey of published trials, we focus on relation between eligibility criteria and effectiveness of intercalated treatment. Methods. Published documents were identified using major medical databases, conference proceedings and references of published trials. Median progression-free survival (PFS) was taken as the basic parameter of treatment efficacy. Correlation between characteristics of patients and median PFS was assessed through the Pearson%s correlation coefficient and the coefficient of determination, separately for first-line and second-line setting. Results. The series includes 11 single-arm trials and 18 randomized phase II or phase III trials with a total of 2903 patients. Treatment-naive patients or those in progression after first-line treatment were included in 16 and 13 trials, respectively. In 14 trials, only patients with non-squamous histology were eligible. Proportion of patients with nonsquamous carcinoma (in first-line setting), proportion of never-smokers (both in first- and second-line setting) and proportion of epidermal growth factor receptor (EGFR) mutant patients (both in first- and second-line setting) showed a moderate or strong correlation with median PFS. In six trials of intercalated treatment applied to treatment-naive EGFR%mutant patients, objective response was confirmed in 83.1% of cases and median PFS was 18.6 months. Conclusions. Most suitable candidates for intercalated treatment are treatment-naive patients with EGFR%mutant tumors, as determined from biopsy or liquid biopsy. For these patients, experience with intercalated treatment is most promising and randomized trials with comparison to the best standard treatment are warranted.
