Publication Acceptable adverse outcomes after delayed breast reconstruction using abdominal advancement flap - A 15-year experience(2016) ;Kosovac, Olivera (57191577661) ;Santrac, Nada (56016758000) ;Markovic, Ivan (7004033833) ;Gavrilovic, Dusica (8849698200) ;Martinovic, Aleksandar (56120118800) ;Jevric, Marko (43761174500) ;Spurnic, Igor (56613372800)Dzodic, Radan (6602410321)Purpose: To evaluate the adverse outcomes after delayed breast reconstruction (DBR) by abdominal advancement flap (AAF) and permanent prosthesis in patients treated with mastectomy due to unilateral breast carcinoma, as well as to determine which factors are predictive for their occurrence. Methods: The study included 155 patients operated at the Institute for Oncology and Radiology of Serbia from 1996 to 2010. All patients had total mastectomy and axillary lymph node dissection, followed by specific oncological treatment. Patients were selected for DBR after complete diagnostic evaluation. Adverse events were evaluated in regard to patient, disease and prostheses-related factors. Results: During follow-up, DBR adverse events were observed in 23.23% of the patients - the majority (91.67%) had only one. The most frequent was capsule contracture (47.22%), followed by asymmetry (22.22%), infection (16.67%) and prosthesis rupture (16.67%). There were isolated cases of prosthesis prolapse and local disease recurrence. Infections were treated conservatively in all but one patient. Other events were managed by additional operation. Statistical analysis showed that complications occurred significantly more often in patients ≥51 years (vs 18-40, vs 41-50), disease stage IIb (vs Ia), T2 (vs TI) tumors and adjuvant radiotherapy (vs without). Prostheses-related factors were not significant for DBR complications, neither body mass index (BMI), nor smoking habits. Conclusions: DBR using AAF and permanent prosthesis is a safe technique with acceptable complication rate. It provides one-time surgery with satisfactory aesthetic results and good postoperative recovery. Most frequent complication is capsule contracture. Patients' age and irradiation of the chest wall after mastectomy are predictive factors for complications. - Some of the metrics are blocked by yourconsent settings

Publication Angiogenic and lymphangiogenic profiles in histological variants of papillary thyroid carcinoma(2017) ;Skuletic, Vesna (6506252136) ;Radosavljevic, Gordana D. (7003547101) ;Pantic, Jelena (55794300000) ;Markovic, Bojana Simovic (56118146400) ;Jovanovic, Ivan (55044296300) ;Jankovic, Nikola (55569168500) ;Petrovic, Dusica (37261641900) ;Jevtovic, Andra (57194724361) ;Dzodic, Radan (6602410321)Arsenijevic, Nebojsa (6507926547)Introduction Papillary thyroid carcinoma (PTC) is a well-differentiated tumor that occurs in several histological variants whose biological behaviors remain unclear. Angiogenesis and lymphangiogenesis are critical processes that enable tumor progression. Objectives The aim of this study was to evaluate the angiogenic and lymphangiogenic phenotypes of PTC, considering the differences between histological variants. Patient s an d met hods Angiogenic and lymphangiogenic profiles were analyzed by determining microvascular density (MVD) and lymphatic vessel density (LVD) in 73 cases of PTC, using immunohistochemistry. To assess the biological markers involved in blood and lymph vessel formation, the expression of vascular endothelial growth factor (VEGF), cyclooxygenase 2 (COX-2), and p27kip1 (p27) was determined. Result s MVD was significantly higher in patients with high-risk PTC and in those with local extrathyroidal and vascular invasion. Positive VEGF expression was strongly associated with high MVD and age-related tumor enlargement. The presence of lymph vessel invasion was associated with the expression of either VEGF or COX-2. The analysis of angiogenesis and lymphangiogenesis in different histological variants of PTC revealed elevated LVD rather than MVD in the follicular variant of PTC (FV-PTC). Lower MVD was observed in FV-PTC relative to the classic variant of PTC (CV-PTC). The frequency of VEGF-positive tumors was higher in CV-PTC than in FV-PTC. A significant association between COX-2 and p27 expression was observed in FV-PTC but not in CV-PTC. Conclusions These results suggest that VEGF, COX-2, and p27 may be important biological markers that determine the angiogenic and lymphangiogenic potentials of PTC, particularly between the follicular and classic variants. © Medycyna Praktyczna, Kraków 2017. - Some of the metrics are blocked by yourconsent settings
Publication Can we use frozen section analysis of sentinel lymph nodes mapped with methylene blue dye for decision making upon one-time axillary dissection in breast carcinoma surgery in developing countries?(2015) ;Djurisic, Igor (13411475700) ;Santrac, Nada (56016758000) ;Buta, Marko (16202214500) ;Oruci, Merima (57189327361) ;Markovic, Ivan (7004033833) ;Nikolic, Srdjan (56427656200) ;Zegarac, Milan (6507699450)Dzodic, Radan (6602410321)Purpose: To evaluate the accuracy of intraoperative frozen section analysis (FSA) of sentinel lymph nodes (SLNs) mapped using methylene blue dye (MBD) and its usefulness for selecting patients with breast carcinomas and positive axillary lymph nodes (ALNs) for one-time axillary dissection. Methods: 152 female patients with T1/T2 breast carcinomas and clinically negative ALNs were selected for mapping using MBD (1%) from October 2010 to December 2011. Patients underwent FSA of mapped SLNs and ALN dissection. The accuracy of SLN-FSA was tested by comparing these findings with the definite histopathology (HP) of SLNs, as well as of other ALNs. Sensitivity, specificity, positive and negative predictive values were calculated. Results: There was a 98%-match between FSA and definite HP findings of SLNs, suggesting high accuracy of FSA in this series. None of 3 patients with false-negative SLNs on FSA had additional axillary nodal metastases. One out of 20 (5%) patients with metastases in other ALNs had "clear" SLNs, both on FSA and definite HP (false-negative). Accuracy reached 94.1%. Conclusions: SLN-FSA enables adequate selection of patients for one-time axillary node dissection. MBD mapping technique is cheap, feasible and enables easy and precise detection of the first draining ALNs. Using FSA of SLNs mapped with MBD, patients with breast carcinoma benefit from complete surgical treatment during one hospitalization, the risk of undergoing anaesthesia twice is reduced, as well as the treatment cost, which is important in developing countries. - Some of the metrics are blocked by yourconsent settings

Publication Cigarette smoking as a risk factor for cancer of the thyroid in women(2004) ;Zivaljevic, Vladan (6701787012) ;Vlajinac, Hristina (7006581450) ;Marinkovic, Jelena (7004611210) ;Paunovic, Ivan (55990696700) ;Diklic, Aleksandar (6601959320)Dzodic, Radan (6602410321)Aims and background: Thyroid cancer, whose etiology is largely uncertain, has been negatively associated with cigarette smoking in a several studies. We examined the association between cigarette smoking and risk for female thyroid cancer. Methods: A case-control study including 204 histologically verified female thyroid cancer patients and an equal number of hospital controls individually matched with cases by sex, age (± 2 years), place of residence and time of hospitalization was carried out during the period 1996-2000. In the analysis of data, univariate and multivariate conditional logistic regression methods were applied. Results: According to univariate analysis, female thyroid cancer was negatively associated with the initiation of smoking at a younger age, before the age of 20 (OR = 0.66, 95% CI = 0.50-0.90). None of the smoking habits remained independently related to female thyroid cancer after adjustment for other factors which were significantly associated with thyroid cancer in the present study. Conclusions: The results of the study do not suggest a role of cigarette smoking in the development of thyroid cancer in women. - Some of the metrics are blocked by yourconsent settings

Publication Genetic alterations in quadruple malignancies of a patient with multiple sclerosis: Their role in malignancy development and response to therapy(2014) ;Milosevic, Zorica (57209726720) ;Tanic, Nikola (7801574805) ;Bankovic, Jasna (24278374400) ;Stankovic, Tijana (55321765700) ;Buta, Marko (16202214500) ;Lavrnic, Dragana (6602473221) ;Milovanovic, Zorka (25228841900) ;Pupic, Gordana (6507142544) ;Stojkovic, Sonja (55915641500) ;Milinkovic, Vedrana (35810904900) ;Ito, Yasuhiro (35427371100)Dzodic, Radan (6602410321)Multiple cancers represent 2.42% of all human cancers and are mainly double or triple cancers. Many possible causes of multiple malignancies have been reported such as genetic alterations, exposure to anti-cancer chemotherapy, radiotherapy, immunosuppressive therapy and reduced immunologic response. We report a female patient with multiple sclerosis and quadruple cancers of different embryological origin. Patient was diagnosed with stage III (T3, N1a, MO) medullary thyroid carcinoma (MTC), multicentric micropapillary thyroid carcinoma, scapular and lumbar melanomas (Clark II, Breslow II), and lobular invasive breast carcinoma (T1a, NO, MO). All tumors present in our patient except micropapillary thyroid carcinomas were investigated for gene alterations known to have a key role in cancer promotion and progression. Tumor samples were screened for the p16 alterations (loss of heterozygosity and homozygous deletions), loss of heterozygosity of PTEN, p53 alterations (mutational status and loss of heterozygosity) and mutational status of RET, HRAS and KRAS. Each type of tumor investigated had specific pattern of analyzed genetic alterations. The most prominent genetic changes were mutual alterations in PTEN and p53 tumor suppressors present in breast cancer and two melanomas. These co-alterations could be crucial for promoting development of multiple malignancies. Moreover the insertion in 4th codon of HRAS gene was common for all tumor types investigated. It represents frameshift mutation introducing stop codon at position 5 which prevents synthesis of a full-length protein. Since the inactivated RAS enhances sensitivity to tamoxifen and radiotherapy this genetic alteration could be considered as a good prognostic factor for this patient. - Some of the metrics are blocked by yourconsent settings
Publication In situ preservation of parathyroid glands: Advanced surgical tips for prevention of permanent hypoparathyroidism in thyroid surgery(2017) ;Dzodic, Radan (6602410321)Santrac, Nada (56016758000)Hypoparathyroidism (HPT) is one of the most frequent and severe complications of thyroid surgery. It is caused by intraoperative damage, devascularization or accidental removal of the parathyroid glands (PTGs). The incidence of postoperative HPT is directly proportional to surgery extent and surgeon’s experience. After 40 years of experience in thyroid surgery, the first author summarizes the already known surgical steps in thyroid surgery and adds some useful practical tips for in situ preservation of PTGs. Our surgical technique focuses on meticulous capsular dissection and preservation of the middle thyroid, Kocher’s vein trunk, as well as vein branches that accompany the posteri- or branch of the superior thyroid artery and inferior thyroid artery trunk. Ligation of all blood vessels should be as close as possible to the thyroid capsule. Identified PTGs should be de-attached from the thyroid capsule on the vascular pedicle without significant dislocation. PTGs preservation during central neck dissection (CND) can be facilitated by using methylene blue dye for sentinel lymph nodes biopsy. PTGs are not colored in blue, unlike central lymph nodes, which facilitates central neck dissection and reduces the possibility of accidental removal of PTGs. After several thousands of preserved PTGs using this original technique, a total prevalence of permanent HPT in the first author’s series is less than 0.5%. Following given key points and recommendations to surgical in situ preservation of PTGs, a surgeon can provide good outcome for patients after total thyroidectomy (with or without central neck dissection), regarding HPT as one of the most severe complications of thyroid surgery. © 2017 Zerbinis Publications.

Publication Long-term Survival after cerebellar metastasis resection from Her2 3+ locally advanced breast cancer(2015) ;Tomasevic, Zorica I. (6701534633) ;Tomasevic, Zoran M. (57211785853) ;Kovac, Zeljko (36632316200) ;Milovanovic, Zorka (25228841900) ;Grujicic, Dana (7004438060)Dzodic, Radan (6602410321)We present a patient who first developed a distant metastatic site in the cerebellum during treatment for Her2 3+ locally advanced breast cancer (LABC). LABC was in complete remission at that time and isolated cerebellar metastasis was resected. The patient is still alive more than 135 months after LABC diagnosis, and more than 99 months after neurosurgery, and is still receiving trastuzumab without further progression or any toxicity. To the best of our knowledge, this is first report of such exceptional disease course for a patient with a predicted grave prognosis according to all prognostic parameters. - Some of the metrics are blocked by yourconsent settings

The correlation between tumor characteristics (size, multifocality, bilaterality, capsular invasion) and LNMs was analyzed. 0Methods: During a 10-year-period (2004-2013), 111 clinically NO patients with PTMCs had total thyroidectomy, central neck dissection and SLN biopsy of the lateral neck compartment in our institution. SLN mapping was performed by subcapsular injection of 0.2 to 0.5ml of 1% methylene blue dye. IfSLNs were positive on frozen section, one-time sLND was done. Results: Forty percent of PTMCs were multicentric. LNMs were detected in 25% of the patients and isolated central LNMs were found in 18% of the patients. Lateral LMNs were present in 7% of the patients, of which 4% were isolated, skip LNMs. All these patients had therapeutic sLND. Specificity and sensitivity of SLN biopsy were 100% and 57%, positive and negative predictive values were 100% and 97%, respectively. Method's accuracy was 97%. Conclusions: SLN biopsy of the lateral neck compartment is more precise than physical examination and ultrasonography for detection of lateral LNMs in clinically NO patients with PTMCs. Intraoperative assessment of lateral lymph nodes (SLNs) provides one-time therapeutic dissection for patients with occult LNMs at initial operation, reducing the need for additional operations.

The aim of this study was to determine the incidence of single PTC focus in PL and its lymphonodal metastases, as well as to present a single surgeon experience in management of PL PTC. We performed a retrospective analysis of records of all patients surgically treated for PTC in our institution from year 2003 to 2013. Only patients with single PTC focus in PL were included. Out of total 753 patients, majority (66.52%) had PTC focus in one of the lobes, while only 3 patients (0.4%) had solitary PTC focus in PL. They were all females, aged 36, 41 and 22. During surgery, methylene-blue dye was injected peritumorally. After frozen section analysis of excised PL and isthmus and confirmation of malignancy, we performed total thyroidectomy with central neck dissection, as well as sentinel lymph node biopsy in both jugulo-carotid regions. Pathology showed encapsulated PTC stage T1 and solitary metastasis in Delphian lymph node of the youngest patient. All patients were disease free in the follow-up. PTC single focus in PL is very rare and only individual experiences can be discussed regarding the extent of the surgery. © The Japan Endocrine Society. - Some of the metrics are blocked by yourconsent settings

Publication Multifocality as independent prognostic factor in papillary thyroid cancer – A multivariate analysis(2018) ;Markovic, Ivan (7004033833) ;Goran, Merima (57189327361) ;Besic, Nikola (6601975829) ;Buta, Marko (16202214500) ;Djurisic, Igor (13411475700) ;Stojiljkovic, Dejan (56320776300) ;Zegarac, Milan (6507699450) ;Pupic, Gordana (6507142544) ;Inic, Zorka (55789800600)Dzodic, Radan (6602410321)Purpose: The incidence of multifocality of papillary thyroid carcinoma (PTC) ranges from 18 to 87.5% The mechanisms of multifocal spreading, correlation with tumor size, histology variants of PTC, lymph node metastases, and prognostic impact remains unclear. The purpose of this study was to clarify the prognostic significance of multifocality on relapse and survival rates of patients with PTC by analyzing the correlation of multifocality with patient age, gender, tumor size, histological variants of PTC, presence of lymph node metastases and extent of surgery. Methods: 153 patients with PTC were included in this study. Patients with pT4 tumors or initially distant metastases were excluded from study. Total thyroidectomy was done in all 153 patients. Central and level III and IV lateral neck lymph node dissection was done in 76.5% of the patients, followed by modified radical neck dissection if positive. Results: Multifocality was found in 43 (28%) whole thyroid gland specimens, and was significantly more frequent in patients older than 45 years and in tumors greater than 4 cm in diameter (p<0.01). Presence of multifocality didn’t significantly correlate with gender, histology variants of PTC or lymph node metastases. In a median follow up of 84 months locoregional relapse occurred in 8.4% and 1.3% of the patients, while 7.2% patients died due to PTC. The incidence of relapse was significantly higher (p<0.01), and relapse free interval and survival were significantly shorter (p=0.0095, p=0.0004, respectively) in patients with multifocal PTC. Cox multivariate regression analysis showed that multifocality was independent prognostic factor for both disease-free interval (DFI) and cancer-specific survival (CSS) of patients with PTC. Conclusion: Due to high incidence of multifocality and potential prognostic impact, total thyroidectomy should be advocated in all patients with PTC, aiming to reduce relapse rate and improve DFI and CSS. © 2018 Zerbinis Publications.

Publication Prognostic importance of steroid receptor status for disease free and overall survival after surgical resection of isolated liver metastasis in breast cancer patients(2017) ;Zegarac, Milan (6507699450) ;Nikolic, Srdan (56427656200) ;Gavrilovic, Dusica (8849698200) ;Kolarevic, Daniela (36089882200) ;Jevric, Marko (43761174500) ;Nikolic-Tomasevic, Zorica (6701534633) ;Kocic, Milan (55386294200) ;Djurisic, Igor (13411475700) ;Inic, Zorka (55789800600) ;Markovic, Ivan (7004033833) ;Buta, Marko (16202214500) ;Ninkovic, Srdan (56956660200)Dzodic, Radan (6602410321)Purpose: Breast cancer (BC) is the most common malignancy among women, while isolated operable liver metastases (LMs)from BC are very rare and occur in only 1-5% of the patients. Besides, positive steroid receptor (SR) status for oestrogen and/or progesterone is known as a factor which improves disease free survival (DFS) and overall survival (OS). The primary aim of this study was to examine the impact ofSR status on DFS and OS after liver metasta-sectomy in female patients with primary BC. Methods: We analyzed 32 medical records of female patients diagnosed and treated for primary BC with LMS as the first and only site of disease progression, at the Institute of Oncology and Radiology of Serbia (IORS), during 2006-2009. All of them underwent primary BC surgery as well as LMs resection. Results: Patients with metachronous BC and LMs and positive SR status in both BC and LM (BC+/LM+) had a median time from BC to LM occurrence (TTLM) of 36 months, compared to BC+/LM- and BC-/LM- subgroups, whose medians for TTLM were 30.5 and 14.5 months, respectively (p<0.01). For all patients, positive SR status showed high correlation with longer DFS and OS after LM resection (medians according survival analysis for DFS/OS in subgroups BC-/LM-, BC+/LM- and BC+/LM+ were 10/19, 25/45,50/not reached months respectively; p<0.01for DFS/OS). Cox regression analysis confirmed that the subgroup of patients with BC-/LM- had 10.8 and 18.8 higher risk of events for DFS (disease relapse or death) and event for OS (death only), respectively, compared to BC+/LM+ subgroup of patients. Conclusion: Positive SR status in BC and LM has a high impact not only on time from BC to LM occurrence, but also on longer DFS and OS after LM resection. - Some of the metrics are blocked by yourconsent settings
