Primary pulmonary choricarcinoma
Žiga Snoj, Igor Kocijančič, Erik Škof, 2017, review article

Abstract: The aim of the study was to establish whether there are different clinical entities of primary pulmonary choriocarcinoma (PPC) that deserve different diagnostic approach and the most optimal treatment. Patients and methods. A systematic review with PubMed search was conducted to identify studies that reported cases of PPC. The eligibility criteria were histological diagnosis of pulmonary choriocarcinoma and thorough examination of the reproductive organs to exclude potential primary choriocarcinoma in the gonads. Furthermore, to illustrate the review we additionally present a patient referred at our institution. Results. 55 cases (17 men) were included in the review with a median age of 34 years. Women with the history of gestational event showed better survival outcome than women without the history of gestational event. Patients treated with combined modality treatment (surgery and chemotherapy) survived longer than the patients without combined modality treatment. Furthermore, multivariate analysis of prognostic factors showed that the combined modality treatment had independent prognostic significance. Size of the tumour showed significant prognostic influence in univariate and multivariate analysis. Conclusions. PPC is an extreme rarity with variable clinical characteristics and outcome. It is important to capture and treat patients in the early stages of the disease. Women with the history of gestational event may show better survival, therefore genetic examination could help us to predict patient%s prognosis. Surgery followed by adjuvant chemotherapy appears to represent the best treatment for PPC.

CT-guided percutaneous transthoracic needle biopsy of lung lesions - 2-year experience at the Institute of radiology in Ljubljana
Igor Kocijančič, Ksenija Kocijančič, 2007, original scientific article

Abstract: Background. In 1883, Leyden described percutaneous lung biopsy, but it was notuntil 1970s that image guided fine needle chest biopsy gained widespread acceptance. Haaga and Alfidi reported CT-guided thoracic biopsy in 1976. Currently, tissue sampling of a thoracic lesion is indicated when the diagnosis is not obtained by the endobronchial technique and when the cytological diagnosis will modify the stage of the disease or influence the therapeutic strategy. Cytology obtained by small-gauge needle aspiration biopsy confirms the nature of the lesion in 80 - 95% of cases and carry a low incidence of major complications according to the literature. The purpose of this retrospective analysis was to provide basic data about diagnostic accuracy and incidence of pneumothorax and chest tube insertion with respect to percutaneous transthoracic CT-guided needle biopsy of lung lesions. Methods. After positioning of the patient we performed a spiral CT of the thorax with the accordingly placed metal mark, which helped us to set the optimal cutaneous entry point. After that we re-checked the localisation of the lesion and marked the entry point with a pen and clean the surface to keepit sterile. After we applied local anaesthetic subcutaneously, we used coaxial 18G Gallini aspiration biopsy needles with cutting tip for CT- guided aspiration cytologic examination. The length of the needle was chosen according to the distance of the targeted lesion. Results. From January 2005 to January 2007 forty-three patients - 24 men and 19 women who were 26-79 years old (mean +/- SD, 59.8 +/- 10 years) were referred to the Institute of Radiology to undergo the PTNB. One patient was referred twice. Consequently, the hospital records and images of 44 consecutive cases of percutaneous transthoracic fine needle aspiration biopsy procedure were retrospectively analysed.

Radiofrequency ablation of lung tumours - new perspective in treatment of lung neoplasms
Ksenija Kocijančič, Igor Kocijančič, 2007, original scientific article

Abstract: Background. Percutaneous radiofrequency ablation (RFA) is a minimally invasivetechnique used to treat solid tumours. Because of its ability to produce large volume of coagulation necrosis in controlled fashion this technique has been progressively tested as a possible treatment of lung malignancies. Recent clinical studies have shown that RFA enables successful treahnent of relatively small lung malignancies with high rate of complete response and acceptable morbidity and have suggested that the technique could represent a viable alternate or complementary method for patients with non-small cell lung cancer or lung metastases of favourable histotypes who arenot candidates for surgical resection. Conclusions. Initial intenational studies as well as the clinical experience of Institute of Radiology in Clinical Center Ljubljana, although limited, indicated that RFA is mostly welltolerated by patients and also, that it can result in complete necrosis oftargeted lesion. Pneumothorax is most common procedure related complication,occurring in up to 40% of cases, with approx. half of them requiring drainage.

Imaging of small amounts of pleural fluid. Part one - small pleural effusions
Igor Kocijančič, 2005, review article

Abstract: Background. Small pleural effusions are not readily identified on conventionalradiographic views of the chest, but may be an important finding, sometimes leading, via thoracocentesis, to a definitive diagnosis of pleural carcinomatosis, infection or transudate. A small meniscus sign and a medial displacement of the costophrenic angle are the only subtle signs of small accumulations of fluid on posteroanterior chest X-rays. On lateral views the finding of a small meniscus sign in the posterior costophrenic angle is the sign of small pleural effusion. Conclusions. Lateral decubitus chest radiographs were used for many years for the diagnosis of small pleural effusions. In last decades ultrasonography of pleural space becomes a leading real-time method for demonstrating small pleural effusions.

Sonography of pleural space in healthy pregnants - preliminary results
Igor Kocijančič, 2005, original scientific article

Abstract: Background. The purpose of our study was to determine the incidence of sonographically visible normal pleural fluid finding in healthy pregnants. Methods. Chest sonography was performed in 47 pregnant volunteers, searching for pleural fluid, first leaning on the elbow and than in a sitting position. 9-12 MHz linear probe was used. If the result of the first examination was positive (at least 2 mm thick anechoic layer), we repeated the procedure with 3-6 MHz large radius convex probe. Results. The fluid layer of typical wedge-shaped appearance was visible in the pleural space of 28/47 (59.5%) pregnant volunteers, on both sides in 18/47 (38.3%) and unilaterally in 10/47 (21.2%). The mean fhickness of fluid layer (mean of positive results in both positions) was 2.86 mm (SD 1.09 mm, range from 1.8 mm to 6.4 mm). More than 3 mm thick fluid layer was easily detected with 3-6 MHz abdominal convex probe in 7/47 (15%). Conclusions. Small amounts of pleural fluid can sometimes be detected by chest sonography, and hence also by abdominal sonography, in otherwise healthy pregnants. Such a positive result, if isolated, should not be taken as a sign of occult thoracic disease.

Sonographically guided fine-needle aspiration biopsies of adrenal masses in lung cancer patients, eleven-year experience
Igor Kocijančič, 2004, original scientific article

Abstract: Purpose. The aim of this retrospective study was to define the accuracy and safety of the ultrasonographically (US) guided fine-needle aspiration biopsy (FNAB) of the enlarged adrenals in the patients with lung cancer. Patients andmethods. In eleven-year period 64 patients with cytologically proven lung cancer underwent USguided FNABs of adrenal masses. The accuracy of the method was assessed on the basis of cytology findings and the safety on the number ofcomplications reported after the procedure. Results. US-guided aspiration biopsy turned out to be accurate in 58/64 cases (91%), and very safe with only4/64 (6%) minor complications. In 52/58 (90%) cases, the cytology sample was found to be malignant. In 6 cases (10%), isolated adrenal masses were adenomas. Conclnsions. We recommend US guided FNAB as a safe and reliable diagnostic method that has many advantages over computer tomography (CT) guided FNAB, such as safety, patient friendliness, no X-rays and its reproducibility.
