A female patient aged 42, started chemotherapy for advanced ovarian carcinoma in June 2016. Considering intraoperative findings, cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) were performed, followed by adjuvant chemotherapy. In March 2018, computed tomography (CT) examination showed disease progression in the form of pleural carcinomatosis with increased levels of tumor markers. In April 2018, total parietal pleurectomy, partial visceral pleurectomy, and then hyperthermic intrathoracic chemotherapy (HITHOC) with cisplatin were performed. The procedure was uneventful, as was the postoperative course. The patient was discharged on the 13th postoperative day with no major postoperative complications. Three months after surgery, CT showed no signs of disease relapse. Since this is a relatively new method of treating pleural carcinomatosis, real results are to be expected with larger series of patients and longer postoperative follow-up.

Purpose: The purpose of this study was to compare two groups in postoperative recovery, whether there were any complications and whether the length of their hospital stay differed. One group received intraoperatively a combination of crystalloids and a small colloid dose, while the other group received only the crystalloids intraoperatively., Methods: This randomized prospective study included 80 patients with colorectal cancer prepared for major elective colorectal surgery. The patients were randomly assigned to either the control group (CG) which received only crystalloid solutions intraoperatively or to the research group (RG) which received a combination of colloid and crystalloid solutions. Regional and general endotracheal anesthesia techniques were combined in all patients. Goal-directed fluid therapy was administered to patients in both groups. After extubation, patients were transferred in the Intensive Care Unit (ICU). We measured the administered fluids, fluid balance, the volume of received red packed cells (RPC) and fresh frozen plasma (FFP). Recorded were the first bowel movement, the first flatus, the tolerance on oral food, complications by Clavian-Dindo classification, days of patient's recovery delay in the ICU, Surgery Department (SD) and the total length of hospital stay (LOS)., Results: Statistically significant differences were present in all parameters of postoperative recovery. RG patients showed better results relative to the CG patients. RG patients were faster in restoring bowel movement and peristalsis, get the first postoperative stool and re-acquire oral food tolerance. According to the Clavian-Dindo classification of complications, no significant difference between these two groups was noted., Conclusions: Goal-directed colloid-crystalloid therapy significantly improved postoperative recovery.

Purpose: The aim of this study was to analyze outcomes of breast conserving surgery (BCS) after neoadjuvant treatment (NAT) in comparison to radical mastectomy (RM) after NAT in terms of disease-free survival (DFS), overall survival (OS) and patients' satisfaction with the esthetic outcomes of surgery., Methods: This prospective study was conducted at the National Cancer Research Center of Serbia, Belgrade, from January 1st 2011 to December 31st 2015, on breast carcinoma patients receiving NAT. Treatment outcome was assessed by MDAPI (MD Anderson Prognostic Index). Female patients (n=52) with satisfactory clinical response to NAT and MDAPI scores 0 or 1 were included into the treatment group (NAT-BCS group). The control group (NAT-RM group) consisted of patients (n=52) with poorer clinical response and MDAPI scores 2 to 4. On check-ups, local or distant relapses were noted and both groups were asked to value their satisfaction with the esthetic outcomes of surgery using the Likert scale., Results: OS was 100% in both groups. DFS was 96.1% in NAT-BCS group and 100% in NAT-RM group. Local recurrences were observed in two patients from the age group ≥60 years, with initial disease stage IIIA and "clear" resection margins on frozen section study. Patients in the NAT-BCS group were more satisfied with the esthetic outcome of surgery than the control group., Conclusions: BCS after NAT provides good esthetic outcome and is oncologically safe if adequate clinical response is achieved after NAT and if established criteria for patient selection are followed.

Background: Carcinoid tumors are rare tumors most commonly found in the gastrointestinal tract. They represent the most common malignancies of the appendix. As a distinct entity from both adenocarcinomas and carcinoids, Goblet cell carcinoid (GCC) was initially described in the literature in 1969. The GCC is almost exclusive to the appendix, but rarely can be found in rectum, ileum and colon. More than 50% of the patients at the time of diagnosis already have advancedstage disease. The most common metastatic sites are the peritoneal surfaces of the pelvis and abdominal cavity, and ovaries in women. Surgery is the main form of treatment in patients with GCC., Case Presentation: A 49-year-old woman was treated at the Institute of Oncology and Radiology of Serbia with histopathological findings of GCC. In a 8-year period the patient was treated with initial appendectomy and three more operations because of locoregional disease progression. The last operation was performed in March 2016 because of endometrial metastases. Since then the patient is on regular follow up without disease progression., Conclusion: GCC is a very rare entity. Multidisciplinary approach is necessary for adequate patient treatment.

Purpose: To determine whether there was a correlation between the type of administered infusion solutions intraoperatively with the quantity of administered infusion solutions, differences in values of cardiac output (CO) and cardiac index (CI) and need to use vasopressors and inotropes, between control and research groups., Methods: This randomized prospective study included 55 patients with colorectal cancer. Subjects in the control group received only crystalloid solutions intraoperatively and postoperatively. The patients in the research group received a combination of colloid in dosage of 10mg/kg and crystalloid solutions. Patients in both groups were given goal directed fluid therapy., Results: The control group received a significantly larger amount of crystalloid solution per kg of body weight during the entire surgical operation, in comparison with the volume of crystalloids in the research group (mean±SD 50.78±28.13 vs. 31.63±25.60 respectively, p=0.01). During the first hour of the surgery, the control group received a larger quantity of fluid in comparison with the research group (mean±SD 31.14±9.78 vs. 22.17±9.92 respectively, p=0.001). From the beginning of anesthesia until 6th postoperative hr the values of CI were significantly higher in the research group in comparison with the control group., Conclusions: Goal directed fluid therapy with colloids, followed by crystalloids during surgery, decreased the total intraoperative fluid volumes, and provided higher values of CI intraoperatively which were also maintained postoperatively.

Purpose: Renal cell carcinoma (RCC) is the most common malignant kidney tumor in adults. Dysregulation of the cell cycle can lead to cancer development. In this study, the mitosis-associated cyclin A and p16, a negative controller, were investigated as potential key points in the RCC development., Methods: This retrospective study included 74 patients with RCC. The expression of cyclin A and p16 and their correlation to histopathological parameters (TNM stage, histological subtype, nuclear grade, tumor size), gender, age, and clinical outcome were studied and analyzed., Results: The highest median value for cyclin A (40%; range 0-70)) and for p16 (57.5%); range 35-80) were found in the papillary histological subtype. Survival analysis showed that in the group of patients that had died before September 2015, the median value for cyclin A was 20% (range 0-60), which was significantly higher than 5% (range 0-70), found in the group of patients that survived (p=0.019)., Conclusions: In relation to the histological subtype, the papillary type of RCC was associated with a significantly higher expression of cyclin A and p16 compared to other subtypes of RCC. High expression of cyclin A indicated worse prognosis, therefore cyclin A could be considered to be a significant prognostic marker.

Purpose: Ovarian cancer (OC) ranks fifth in mortality among females cancer patients. Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) have radically changed the treatment of OC. The aim of this study was to evaluate overall survival (OS) and disease-free survival (DFS) in our patient population after the application of combined CRS and HIPEC treatment., Methods: The study included patients who met defined inclusion and exclusion criteria and had undergone CRS of peritoneal carcinomatosis from 2006 to 2011. Tumor extension was intraoperatively calculated using peritoneal cancer index (PCI). After CRS had been performed, selected patients underwent closed HIPEC. Assessment of successful surgery was estimated with the completeness of cytoreduction score., Results: The study involved 31 patients. The median DFS was 19 months. The DFS for 1 and 2-year period were 69.2 and 35.2%, respectively. The mean OS was 51 months. The 1-, 2- and 5-year OS was 85.4, 63.3 and 56.3%, respectively. PCI ranged from 1 to 24 and the majority (77.4%) of the patients had PCI score below 13. The most frequent carcinomatosis was observed in the omentum (80.6%), followed by adnexae (61.3%), uterus (58.1%), colon (58.1%). spleen (25.8%), diaphragm (25.8%), small intestine (19.4%), bursa omentalis 19.4, liver (9.7%), and pancreas (3.2%)., Conclusion: The results of the current study are in concordance with the literature which clearly favors combined the CRS and HIPEC treatment. The reported data suggest that this method could be successfully applied in our region and outline the necessity of future multicentric studies that will involve major regional hospitals.

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.

Purpose: The aim of this research was to examine overall (OS) and disease-free survival (DFS) in patients with colorectal peritoneal carcinomatosis (CRC-PC), treated with cytoreductive surgery (CRS) and intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC), as well as to analyse factors of prognostic significance., Methods: We included 61 patients with pathological/and computerized tomography (CT) confirmation of CRC-PC, treated with CRS+HIPEC from 2005 to 2012. Peritoneal Cancer Index (PCI) score was used for quantitative assessment of the CRC-PC extent. We performed CRS following the Sugarbaker's principles in all patients with PCI ≤20 and only in 3/61 (4.92%) patients with PCI >20. HIPEC (oxaliplatin 410 mg/m(2) in 2000mL isotonic solution and 41?C) was performed using RanD Performer® HT perfusion system during 30-60 min. Cox proportional hazard regression was used to determine significant factors for OS and DFS., Results: The follow-up ranged from 1 to 83 months (median 22). Median OS was 51 months (95% confidence interval/ CI 22+). Median DFS for patients without residual disease (57/61, 93.44%) was 23 months (95% CI 16+). One-, 2- and 6-year OS (DFS) were 78.6% (68.3%), 58.7% (46.7%) and 50.5% (38.1%), respectively. By the end of the study, 55.74% of the patients were still alive. Cox multivariate analysis indicated PCI score as a parameter of highly prognostic significance for patients treated with CRS+HIPEC (p<0.001). Patients with PCI (13 (vs PCI ≥13) had significantly longer OS and DFS (p<0.001), also confirmed for PCI subcategories (PCI <7 vs 7≤ PCI <13 vs PCI ≥13). All patients with PCI <7 are still alive., Conclusion: Our study indicates that CRS+HIPEC significantly improves the survival of CRC-PC patients. This treatment modality should be considered as the most suitable in well-selected patients with this disease.
