The aim of this study is to evaluate influence of allogeneic blood transfusion on prognosis in patients in Dukes B stage of colorectal cancer. All patients with colorectal cancer who were admitted at our Department of Surgery between January 2000 and December 2004 were analyzed. One hundred fifty-one patients who fulfilled inclusion criteria were enrolled in further evaluation. B stage according to Dukes classification and curative resection were inclusion criteria. Exclusion criteria were polyposis syndromes, nonpolyposis syndromes, inflammatory bowel disease, autoimmune disease and previous blood transfusion. Patients were divided into two groups: Group 1 received ≤3 units of allogeneic blood transfusion and group 2 received >3 units of allogeneic blood transfusion. "Cutoff" value of 3 units of blood was defined according to our results and literature data. Follow-up was 5 year. There was no statistical difference between these groups in local recurrence (χ2 = 0.009, P > 0.05) and distant metastasis (χ2 = 0.44, P > 0.05). Also, the Kaplan-Meier survival curves were calculated, and long-rank test did not show a survival difference between these two groups (log rank = 0.075, P > 0.05). Postoperative complications are significantly more frequent in Group 2 (χ2 = 4.67, P < 0.05). Multivariate logistic regression analysis confirmed that intraoperative blood transfusion more than three units had independent influence on local recurrence. Postoperative transfusion more than 3 units was statistically independent prognostic factor for metastasis and mortality. Overall transfusion less than 3 units of allogeneic blood does not influence the outcome of patients in Dukes B stage of colorectal cancer. © 2010 Springer Science+Business Media, LLC.

Angiosarcoma of the breast is a rare and very aggressive tumors originated from endothelial cells lining blood vessels. We report a case of a 55-year-old postmenopausal female with a primary breast angiosarcoma diagnosed just a one year after radical hysterectomy and radiation therapy due to endometrial cancer. The patient initially presented with postmenopausal bleeding. Cytology and biopsy of the endometrium were performed and endometrial adenosquamous carcinoma was diagnosed followed by radical hysterectomy and postoperative local radiatiotherapy (50 Gy). One year later patient presented with a great painful tumorous mass in the right breast. Physical examination revealed an oval tumor, located in upper and outer quadrant of the right breast, around 15 cm in diameter. Mammography and ultrasonography were performed. The angiosarcoma of the breast was confirmed by biopsy. The patient unDerwent radical mastectomy. Histopathology proved the diagnosis of angiosarcoma (high-grade, numerous mitoses over 10/10 HPF, necrosis, "blood lakes", infiltrative borDers). Differential diagnosis of a breast angiosarcoma should be consiDered in all painful breast tumours no mather the time and the location of the previous radiation treatment even if benign characteristics of these masses have been detected by mammography and breast ultrasound. © 2012 Versita Warsaw and Springer-Verlag Berlin Heidelberg.

Background: Total gastrectomy causes numerous disorders, such as reflux esophagitis, dumping syndrome, malabsorption, and malnutrition. To minimize the consequences, different variants of reconstruction are performed. The aim of our study is the comparison of two reconstructive methods: the standard Roux-en-Y and a new modality of pouch interposition, preduodenal-pouch interposition. This study aims to investigate the advantage of bile reflux prevention and to reduce symptoms of dumping syndrome after 3- and 6-mo follow-up. Materials and Methods: A total of 60 patients were divided in two groups: (A) 30 patients with Roux-en-Y reconstruction, and (B) 30 patients with the preduodenal-pouch (PDP) type of reconstruction. Endoscopic examination and endoluminal jejunal limb pressure measurements were performed. Scintigraphic measurements of half-emptying time were performed to evaluate meal elimination in the context of reflux esophagitis and early dumping syndrome. The Japan Society of Gastrointestinal Surgery has provided guidelines with which to classify the symptoms of early dumping syndrome. Patients were followed up for periods of 3 and 6 mo after the surgery. Results: Our study groups did not differ with regard to the level of reflux esophagitis (P = 0.688). Average values of pressure at 10 and 15 cm below the esophago-jejunal junction were significantly lower in the PDP group (P < 0.001). Elimination of the test meal between two groups was not significant (P = 0.222). Evaluation of early dumping syndrome symptoms revealed a significant reduction among PDP patients after 3 and 6 mo. Conclusion: Our study showed significant superiority of the new pouch reconstruction over the standard Roux-en-Y approach in the treatment of early dumping syndrome. © 2012 Elsevier Inc.

The incidence of breast carcinoma following prophylactic mastectomy is probably less than 2%. We present a 43-year-old female to male transsexual who developed breast cancer 1 year after bilateral nipple- sparing subcutaneous mastectomy as part of female to male gender reassignment surgery. In addition to gender reassignment surgery, total abdominal hysterectomy with bilateral salpingo-oophorectomy (to avoid the patient from entering menopause and to eliminate any subsequent risk of iatrogenic endometrial carcinoma), colpocleisys, metoidioplasty, phalloplasty, urethroplasty together with scrotoplasty/placement of testicular prosthesis and perineoplasty were also performed. Before the sex change surgery, the following diagnostic procedures were performed: breast ultrasound and mammography (which were normal), lung radiography (also normal) together with abdominal ultrasound examination, biochemical analysis of the blood and hormonal status.According to medical literature, in the last 50 years only three papers have been published with four cases of breast cancer in transsexual female to male patients. All hormonal pathways included in this complex hormonal and surgical procedure of transgender surgery have important implications for women undergoing prophylactic mastectomy because of a high risk of possible breast cancer. © 2012 Nikolic et al.; licensee BioMed Central Ltd.

Background: We present a surgical technique and the preliminary results of breast cancer excision after insertion of a specially constructed marking needle into the tumor, controlled by intraoperative ultrasound. Methods: Detailed description of the technique is given. Thirty-two female patients undergoing breast-conserving surgery, up to 30 mm in diameter, for palpable and non-palpable invasive breast cancer, were operated on using this technique. Its feasibility was tested by analyzing the success (rate) of needle placement in the tumor, the measurements executed, and the performance of the excision. Results: All stages of the technique were successfully performed to completion on all 32 patients. The procedure of needle placement and ultrasound measurement of distances took 11 min on average (between 6 and 20 min). The average distance of the tumor margin from the resection margin was 12.9 mm (2 to 30 mm, 95% confidence interval [11.9, 14.06]). There was one patient with a positive resection margin (3%). Conclusions: The technique of excising palpable and non-palpable breast cancer by intraoperative ultrasound and an especially constructed marking needle is feasible and comfortable to perform. Preliminary results imply that resection volume can be rationalized, with the same or better oncological safety. © Ivanovic et al.; licensee BioMed Central.

Purpose: A multidisciplinary approach to the treatment of patients with malignant diseases requires adequate venous access in order to safely administer chemotherapy, blood transfusion and blood products, antibiotics, rehy-dratation and total parenteral nutrition. The insertion of the central venous catheter (CVC), its use and its maintenance can be accompanied by multiple complications.; Methods: Fifty cancer patients were retrospectively enrolled in this study. The obligatory inclusion criterion was an implanted CVC of the port-a-cath type, inserted for chemotherapy administration. This study included patients who had their catheters inserted in the period from 2001 to 2012.; Results: The median patient age was 44 years (range 28-68). Thirty five patients (70%) were female and 15 (30%) male. The port-a-cath had been used from Ito 40 months (16.8±9 months on average). Breast cancer was the most frequent malignancy (18 patients, 36%). The overall incidence of reported complications was 38%. The most common complications were infections and thromboembolic events, each with an incidence of 10 %. The malposition and disconnection of the port-a-cath were in second place, each with an incidence of 6%.; Conclusion: Insertion of the CVC carries the possibility of serious complications (thrombosis, infections, occlusions). However, correct implantation and handling performed by experienced and trained surgical and other medical staff significantly decrease the incidence of these complications. The use of the CVC has greatly improved the quality of life and also decreased the morbidity and mortality of the cancer patients in our study.

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. © 2018 Zerbinis Publications.
