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.

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.

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.
