RESUMEN

INTRODUCTION: Vaccination against coronavirus disease-19 (COVID-19) is highly effective in preventing severe disease and mortality. Adenoviral vector and mRNA vaccines were effective against intensive care unit (ICU) admission, but the effectiveness of inactivated vaccine on ICU admission was unclear. We aimed to evaluate the effect of vaccination status on ICU admission in hospitalized COVID-19 patients in a country with heterologous vaccination policy. METHODOLOGY: This is a retrospective multicenter study conducted in three hospitals in Izmir, Turkey between 1 January 2021 and 31 March 2022. Patients aged ≥ 18 years and hospitalized due to COVID-19 were included in the study. Patients who had never been vaccinated and patients who had been vaccinated with a single dose were considered unvaccinated. A logistic regression analysis was performed for evaluating risk factors for ICU admission. RESULTS: A total of 2,110 patients were included in the final analysis. The median age was 66 years (IQR, 53-76 years) and 54% of the patients were vaccinated. During the study period, 407 patients (19.3%) were transferred to the ICU due to disease severity. Patients who were admitted to the ICU were older (median age 68 vs. 65 years, p < 0.001); and the number of unvaccinated individuals was higher among ICU patients (57% vs. 45%, p < 0.001). In multivariate regression analysis, being unvaccinated was found to be the most important independent risk factor for ICU admission with an OR of 2.06 (95% CI, 1.64-2.59). CONCLUSIONS: Vaccination against COVID-19 is effective against ICU admission and hospital mortality.

RESUMEN

BACKGROUND: The COVID-19 (coronavirus disease 2019) pandemic is a global health emergency that is straining health care resources. Identifying patients likely to experience severe illness would allow more targeted use of resources. This study aimed to investigate the association between the thymus index (TI) on thorax computed tomography (CT) and prognosis in patients with COVID-19. METHODS: A multicenter, cross-sectional, retrospective study was conducted between March 17 and June 30, 2020, in patients with confirmed COVID-19. The patients' clinical history and laboratory data were collected after receiving a signed consent form. Four experienced radiologists who were blinded to each other and patient data performed image evaluation. The appearance of the thymus was assessed in each patient using 2 published systems, including the TI and thymic morphology. Exclusion criteria were lack of initial diagnostic thoracic CT, previous sternotomy, pregnancy, and inappropriate images for thymic evaluation. A total of 2588 patients with confirmed COVID-19 and 1231 of these with appropriate thoracic CT imaging were included. Multivariable analysis was performed to predict the risk of severe disease and mortality. RESULTS: The median age was 45 (interquartile range, 33-58) years; 52.2% were male. Two hundred forty-nine (20.2%) patients had severe disease, and 60 (4.9%) patients died. Thymus index was significantly associated with mortality and severe disease (odds ratios, 0.289 [95% confidence interval, 0.141-0.588; P = 0.001]; and 0.266 [95% confidence interval, 0.075-0.932; P = 0.038]), respectively. Perithymic lymphadenopathy on CT imaging had a significantly strong association with grades of TI in patients with severe disease and death ( V = 0.413 P = 0.017; and V = 0.261 P = 0.002, respectively). A morphologically assessable thymus increased the probability of survival by 17-fold and the absence of severe disease by 12-fold. CONCLUSION: Assessment of the thymus in patients with COVID-19 may provide useful prognostic data for both disease severity and mortality.

RESUMEN

Background: Invasive lobular carcinomas (ILC) account for 10-15% of all breast cancers and are the second most common histological form of breast cancer. They usually show a discohesive pattern of single cell infiltration, tend to be multifocal, and the tumor may not be accompanied by a stromal reaction. Because of these histological features, which are not common in other breast tumors, radiological detection of the tumor may be difficult, and its pathological evaluation in terms of size and spread is often problematic. The SSO-ASTRO guideline defines the negative surgical margin in breast-conserving surgeries as the absence of tumor detection on the ink. However, surgical margin assessment in invasive lobular carcinomas has not been much discussed from the pathological perspective. Methods: The study included 79 cases diagnosed with invasive lobular carcinoma by a Tru-cut biopsy where operated in our center between 2014 and 2021. Clinicopathological characteristics of the cases, results of an intraoperative frozen evaluation in cases that underwent conservative surgery, the necessity of re-excision and complementary mastectomy, and consistency in radiological and pathological response evaluation in cases receiving neoadjuvant treatment were questioned. Results: The tumor was multifocal in 37 (46.8%) cases and single tumor focus in 42 (53.2%) cases. When the entire patient population was evaluated, regardless of focality, mastectomy was performed in 27 patients (34.2%) and breast-conserving surgery (BCS) was performed in 52 patients (65.8%). Of the 52 patients who underwent BCS, 26 (50%) required an additional surgical procedure (cavity revision or completion mastectomy). There is a statistical relationship between tumor size and additional surgical intervention (p < 0.05). BCS was performed in 7 of 12 patients who were operated on after neoadjuvant treatment, but all of them were reoperated with the same or a second session and turned to mastectomy. Neoadjuvant treatment and the need for reoperation were statistically significant (p < 0.05). Additional surgical procedures were performed in 20 (44.4%) of 45 patients in BCS cases who did not receive neoadjuvant therapy. Conclusions: Diagnostic difficulties in the intraoperative frozen evaluation of invasive lobular carcinoma are due to the different histopathological patterns of the ILC. In our study, it was determined that large tumor size and neoadjuvant therapy increased the need for additional surgical procedures. It is thought that the pathological perspective is the determining factor in order to minimize the negative effects such as unsuccessful cosmesis, an additional surgical burden on the patient, and cost increase that may occur with additional surgical procedures; for this reason, new approaches should be discussed in the treatment planning of invasive lobular carcinoma cases.

RESUMEN

OBJECTIVES: This study aimed to evaluate the question as to whether there should be a certain length of the colon-rectum segment to be resected for correct lymph node staging in cases with colorectal cancer. MATERIAL AND METHODS: The files and electronic datas of the patients had been undergone surgery for colorectal cancer between January 2011 and June 2016 were evaluated. The patients were divided into two groups; Group I= ≥ 12 lymph nodes, and Group II= lymph nodes less than 12 ( <12) lymph nodes. RESULTS: Mean age of the 327 participants in this study was 64.30 ± 12.20. Mean length of resected colon-rectum segment was 25.61 (± 14.07) cm; mean number of dissected lymph nodes was 20.63 ± 12.30. Median length of the resected colon was 24 cm (range: 145-6) in Group I and 20 cm (range: 52-9) in Group II; a significant difference was found between the groups (p= 0.002). Factors associated with adequate lymph node dissection included type of the operation (p= 0.001), tumor location (p= 0.005), tumor T stage (p= 0.001), condition of metastasis in the lymph node (p= 0.008) and stage of the disease (p= 0.031). Overall survival was 62.4 ± 1.31 months, and Group I and Group II survival was 61.4 ± 1.39 months and 66.7 ± 3.25 months, respectively (p= 0.449). CONCLUSION: Results of the study showed that ≥ 12 lymph nodes would likely be dissected when the length of the resected colon-rectum segment is > 21 cm. We conclude that the removed colonic size can be significant when performed with oncological surgical standardization.

RESUMEN

BACKGROUND: In this study, we aimed to evaluate the superiority of intracorporeal sutures and Hem-o-lok clips about efficiency, reliability and cost. METHODS: We performed laparoscopic surgery for acute appendicitis in this study. Appendiceal stump was closed by Hem-o-lok clips (Group I) and intracorporeal knotting (Group II) in a randomized manner. Groups were compared for demographic data (age, sex, body mass index, American Society of Anesthesiologists score) operation time, total cost, 2.6.12.24.hours and 7th day pain score. RESULTS: Demographic data, such as age, gender and BMI, were similar between groups (p>0.05). There was no significant difference between the groups concerning peroperative and postoperative complications (p>0.05). No postoperative nausea, vomiting, ileus and intraabdominal abscess were observed in patients. There was no significant difference between the groups about duration of operation, length of hospital stay and cost analysis (p>0.05). There was no significant difference in pain scores of groups. The effect of the operation type on pain scores was not statistically significant (p>0.05). CONCLUSION: This study showed that both intracorporeal knotting and Hem-o-loc clips were effective, reliable and similar cost-effective in laparoscopic appendectomy. The decision should be based on the surgeon's experience.

RESUMEN

Purposes: Formation of peritoneal adhesions is a common consequence of abdominopelvic surgeries and remarkably increases the mortality and morbidity. Moreover, peritoneal adhesions linked to chronic abdominopelvic pain and infertility in women. Various attempts for prevention of peritoneal adhesions were reported. However, these methods either remain insufficient to prevent formation of peritoneal adhesions or carry some practical limitations and thus, there is a need for novel techniques that could effectively decrease the formation of peritoneal adhesions. The aim of the present prospective, randomized, controlled, and single blinded study was to evaluate the effect of non-thermal atmospheric plasma (NTAP) treatment on prevention of peritoneal adhesions. Materials and Methods: Sixteen male CD-1 mice were randomly divided into two groups: control and plasma. Excisional and abrasion adhesion models were generated on the peritoneal side wall and cecum, respectively. Ten days after creating adhesion models, mice were sacrificed and adhesion formations were evaluated macroscopically using Knightly's and Linsky's grading systems to assess the intensity and extent of adhesions, respectively. Zühlke's grading system was used for microscopic assessment of adhesions. Results: The mean scores for peritoneum and cecum in control group according to Knightly's grading system were determined as 3.3 and 2.6, respectively. In NTAP-treated group, Knightly's score was determined as 1.6 and 0.5 for peritoneum and cecum, respectively. NTAP treatment reduced Linsky's score from 3.8 to 1.3 and 2.1 to 1.1 on peritoneum and cecum. Finally, in microscopic evaluation, NTAP treatment reduced Zühlke's score from 3.4 to 1.5 and 2.6 to 1.3 for peritoneum and cecum, respectively. Conclusions: The results of the present proof of concept study suggest that NTAP could be a novel method to reduce and/or prevent the formation of peritoneal adhesions after abdominopelvic surgeries.

RESUMEN

AIM OF WORK: This study investigates the factors related to metastasis detection in a sentinel lymph node biopsy (SLN) in patients without clinical axillary involvement. PATIENTS AND METHODS: The medical records of patients who underwent an SLN biopsy after diagnosis with early-stage breast cancer were evaluated retrospectively. The study sample included 64 patients divided into two groups according to the histopathological examination of the SLN biopsy: Group I (positive for axillary metastasis) and Group II (negative for axillary metastasis). RESULTS: The frequency of lymphovascular invasion was significantly higher in Group I (57%) than in Group II (13%) (p = 0.003). The progesterone receptor status (p = 0.036), tumor T-stage(p = 0,047), and Ki-67 index differed significantly (p = 0.045) between the two groups. While in univariate analysis, lymphovascular invasion, T-stage and KI-67 index were significant, in multivariate analysis only lymphovascular invasion was found to be significant. No significant differences were found in terms of estrogen receptor and HER2 considering tumor invasion type, histologic grade, vascular invasion, neural invasion, multifocality or bilaterality, hormone receptor status, menopause status, total number of lymph nodes, presence of non-sentinel lymph nodes and the number of SLNs in the groups (p > 0.05). CONCLUSIONS: The results of this study indicate that lymphovascular invasion is associated with axillary metastasis, based on an SLN biopsy.

RESUMEN

OBJECTIVE: D2 lymphadenectomy (D2-LND) with curative resection (R0) is the cornerstone of gastric cancer treatment. In this study, we compared survival outcomes of D2-LDN with D1-LDN in patients who had undergone curative resection for Stages II and III primary gastric adenocarcinoma. MATERIAL AND METHODS: Between April 1996 and March 2014, 153 consecutive patients with adenocarcinoma of the stomach underwent total gastrectomy with D1-LND or D2-LND. Among those, 118 patients (38 D1 vs. 80 D2) with a complete history and having been followed for at least 1 year after surgery were enrolled. Both groups were compared in terms of demographic and clinico-pathologic characteristics. RESULTS: The mean follow-up was 42.6±52.5 months (mo.). The demographic characteristics of the groups were similar. The Tumor, Node and Metastases (TNM) stage distribution was 25% for Stage II and 75% for Stage III for both groups. Eighteen patients (47.4%) in the D1 and 47 patients (58.8%) in the D2 group were free from locoregional recurrence. The median disease-free survival was 22.0±4.1 mo. for the D1 and 28.0±4.3 mo. for the D2 group (p=0.36). Eight patients (21%) in the D1 and 39 patients (49%) in the D2 group were alive at the last follow-up. The median overall survival (OS) was 22.0±3.7 mo. for the D1 and 31.0±5.4 mo. for the D2 group (p=0.13). The 5-year disease-free survival and OS by the Kaplan-Meier estimates were 41% vs. 51% and 30% vs. 42% in the D1 and D2 groups, respectively. The median 5-year OS for patients with Stages IIIB and IIIC tumors was 14.0±2.2 mo. for the D1 and 20.0±5.0 mo. for the D2 group, respectively (p: 0.048). CONCLUSION: When compared to D1-LND, D2-LND with R0 resection have yielded a trend toward a better outcome in patients with primary gastric adenocarcinoma.

RESUMEN

BACKGROUND: This study aimed to evaluate the usefulness of Fournier's gangrene scoring index (FGSI) and Uludag FGSI (UFGSI) for predicting mortality in patients with FG. METHODS: Patients who underwent treatment and follow-up in the A division department of general surgery at two education and research hospitals between January 2012 and December 2015 were evaluated for mortality-related factors. The sensitivities of FGSI and UFGSI scoring systems for predicting mortality-related factors and disease prognosis were evaluated. Patients were grouped as survivors (Group I) or non-survivors (Group II). RESULTS: In total, 29 patients were included in the study. The mean age (±SD) was 51.52±13.36 years. The mortality rate was 20.6% (six patients). Bacterial growth was observed in wound cultures of 17 patients (58.6%). Of the patients with bacterial growth, 11 (47.8%) were in Group I and six (100%) were in Group II. The presence of bacterial growth was significantly associated with mortality (p=0.028). Fourteen patients (48.3%) had comorbid conditions. The number of comorbid conditions was related (p=0.049). FGSI and UFGSI scores were significantly higher in Group II than in Group I (p=0.002 and p=0.001, respectively). Among UFGSI parameters, extent of disease, body temperature, pulse rate, and HCO3 values were significantly higher in Group II than in Group I (p<0.05). The FGSI and UFGSI scoring systems had 100% sensitivity and 78.2% and 73.9% specificity, respectively, for predicting mortality. CONCLUSION: The FGSI and UFGSI scoring systems are valuable for predicting mortality in patients with FG. The extent of the disease was an important prognostic parameter in this study. Whichever scoring system is used, we suggest the use of the extent of disease score in UFGSI.

RESUMEN

There is still an ongoing debate, especially regarding early diagnosis of acute appendicitis. Early surgery leads to inadequate evaluation of acute abdominal pain and negative appendectomy, whereas delayed surgery leads to appendicitis perforation complications. The diagnosis of this condition is considerably difficult, especially due to subtle early symptoms and clinical condition. The aim of the present study was to identify whether the Alvarado scoring system could reduce the incidence of negative appendectomy in patients who will undergo surgery for acute appendicitis. Patients who underwent surgery with acute appendicitis prediagnosis were retrospectively classified as negative appendectomies (group A) and positive appendectomies (group B) according to histological diagnosis. All groups were evaluated for age, gender, Alvarado scores, and parameters. Two hundred eighty-one patients were included in the study. Group A contained 71 (25.3 %) patients, and group B contained 210 (74.7 %) patients. There was a significant difference in WBC, left shift, rebound, and change of pain localization between the groups (p = 0.002, p < 0.001, p < 0.001, and p = 0.023, respectively). Alvarado scores were significantly different between the groups (p < 0.001). In logistic model examination, the major factor was the Alvarado score (7 or above) and the minor factor was spreading pain. The Alvarado scoring system can be used to reduce negative appendectomy in patients who will undergo surgery with acute appendicitis.

RESUMEN

Peritoneal invasion is more common and has a worse prognosis in gastric cancer than most of other intestinal cancers. Advanced gastric cancers have a poor course in terms of the development of peritoneal carcinomatosis and prognosis, even if the curative resection has been performed. Patients usually die within the first 2 years of the postoperative period mainly due to peritoneal metastasis. It is, therefore, essential to eradicate intraperitoneal free cancer cells to prevent peritoneal recurrences. A standard therapy has not been developed yet for patients with gastric cancer with a positive peritoneal cytology or a gross peritoneal metastasis. Curative resection following neoadjuvant chemotherapy, postoperative oral S-1 chemotherapy, intraoperative intraperitoneal chemotherapy (IPC), and extensive intraoperative peritoneal lavage (EIPL)-IPC are recommended as therapeutic approaches. Although there is a limited number of studies on EIPL, which is a promising and exciting method in this patient population, unexpected results of survival have been demonstrated. We consider that the results of ongoing and further studies would lead to an extensive use of EIPL, which is a simple and easy method which can be applied anywhere and anytime, in patients with advanced gastic cancer and/or peritoneal cytology positive but peritoneal metastasis negative (CY+/P0) gastric cancer.

RESUMEN

BACKGROUND: This study aimed to propose treatment strategies for high-output chylous ascites (CA) developed after gastric cancer surgery. METHODS: The data of patients with CA after gastric cancer surgery in three high volume Training and Research Hospitals between 2005 and 2015 were retrospectively evaluated. RESULTS: Nine patients out of 436 gastrectomies were detected with CA. The mean amount of daily fistula output was 939 mL. Treatment consisted of cessation of oral feeding, total parenteral nutrition (TPN), somatostatin analogs administration, clamping and/or removal of the drainage tube, diuretic administration and diet therapy with medium-chain triglycerides (MCTs) alone or in combination. The mean fistula closure time and length of hospital stay were 23 and 24 days respectively. Hemopneumothorax developed during right subclavian vein catheterisation for TPN implementation in one patient. There was no mortality. CONCLUSIONS: Combined cessation of oral feeding and TPN are usually used for treatment of CA as first-line treatment. However, TPN is no harmless. Although our data are limited they do allow us to conclude that diet with MCT's may use for medical treatment of CA as first-line.

RESUMEN

Gastric cancer has an important place in the worldwide incidence of cancer and cancer-related deaths. It can metastasize to the lymph nodes in the early stages, and lymph node metastasis is an important prognostic factor. Surgery is a very important part of gastric cancer treatment. A D2 lymphadenectomy is the standard surgical treatment for cT1N+ and T2-T4 cancers, which are potentially curable. Recently, the TNM classification system was reorganized, and the margins for gastrectomy and lymphadenectomy were revised. Endoscopic, laparoscopic and robotic treatments of gastric cancer have progressed rapidly with development of surgical instruments and techniques, especially in Eastern countries. Different endoscopic resection techniques have been identified, and these can be divided into two main categories: endoscopic mucosal resection and endoscopic submucosal dissection. Minimally invasive surgery has been reported to be safe and effective for early gastric cancer, and it can be successfully applied to advanced gastric cancer with increasing experience. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy were developed as a combined treatment modality from the results of experimental and clinical studies. Also, hyperthermia increases the antitumor activity and penetration of chemotherapeutics. Trastuzumab which is a monoclonal antibody interacts with human epidermal growth factor (HER) 2 and is related to gastric carcinoma. The anti-tumor mechanism of trastuzumab is not clearly known, but mechanisms such as interruption of the HER2-mediated cell signaling pathways and cell cycle progression have been reported previously. H. pylori is involved in 90% of all gastric malignancies and Japanese guidelines strongly recommend that all H. pylori infections should be eradicated regardless of the associated disease. In this review, we present innovations discussed in recent studies.

RESUMEN

Because of different prognosis of gastric cancer patients with the same T and N stages, the impossibility of N3 staging in patients with fewer than 15 removed lymph nodes, and the presence of stage migration phenomenon, the 6th edition TNM Staging System for gastric cancer was updated to the 7th edition TNM staging system in 2009. Despite some opposing views, the superiority of the 7th edition TNM staging system compared to the 6th has been demonstrated in many studies. However, there are doubts about the 7th edition that it will reduce the stage migration phenomenon. The most important problem about the 7th TNM staging system is regarding subgroups N3a and N3b. The separation of N3 stage as N3a and N3b does not contribute to the TNM staging system. In conclusion, separate usage of N3a and N3b subgroups in the TNM staging system should be considered in the creation phase of the 8th edition.

RESUMEN

The concomitant presence of breast cancer with one or more other types of cancer such as colon, vulva, lung, larynx, liver, uterus and kidneys has been presented in the literature. However, synchronous breast and renal cancer is very uncommon. Herein we present a woman with synchronous breast and renal cancer, and review the literature. A 77-year-old post-menopausal woman was admitted to our clinic complaining of left sided breast mass. On physical examination, there was a 3 cm palpable mass in the upper outer quadrant of the left breast along with a conglomerate of lymph nodes in the left axilla. Ultrasonography and mammography showed a 3 cm solid, hypoechoic mass in the upper outer quadrant and left axillary lymphadenopathy. The tru-cut biopsy of the lesion revealed invasive ductal carcinoma. The bone scintigraphy, thoracic and cranial computerized tomographies were normal. The abdominal computerized tomography identified a 3×3 cm solid renal mass with heterogeneous contrast enhancement in the posterior segment of the lower pole, which was suspicious for renal cell carcinoma. Breast conserving surgery and axillary lymph node dissection was performed, and the pathology specimen demonstrated invasive ductal carcinoma. The patient was discharged on postoperative day 5. Three weeks later partial nephrectomy was performed by urology department for the solid renal mass, and the pathology result showed clear cell-renal carcinoma with Fuhrman grade 3. The patient is being followed-up for renal carcinoma, and underwent radiotherapy for breast cancer. Hormonotherapy for breast cancer is still continuing.

RESUMEN

BACKGROUND: The aim of this study was to investigate the experience, practice and approaches of general surgeons in relation to the treatment of breast cancer in Turkey. METHODS: A survey was conducted between November 2012 and February 2013 with 453 general surgeons who claimed to perform breast surgery. Initial and most preferred approaches for breast cancer surgery and demographic features of participants were questioned. Initial approaches of surgeons for a suspected breast mass were assessed with a clinical scenario. RESULTS: A total of 12.6 % of practicing general surgeons in Turkey responded to the survey. A multidisciplinary assessment was employed by 57.2 % of participants. The most frequently used diagnostic tool was needle biopsies (64.9 %) and the most frequently performed surgery for early stage cancers was breast-conserving surgery (72.2 %). The initial approach for locally advanced breast cancer was neoadjuvant chemotherapy (59.8 %) and mastectomy for metastatic cancer (22.7 %). Sentinel lymph node biopsies were utilized by 59.2 % of participants by different methods in appropriate cases. Oncoplastic breast surgery was performed by 9.0 % of participants, frequently or constantly. The surgeons' initial approaches for the clinical scenario were imaging (56.7 %) and biopsy (40.6 %). CONCLUSIONS: Although there are efforts to improve up-to-date approaches towards breast cancer surgery by surgeons, currently there are significant inadequacies for evidence-based medicine practices.

RESUMEN

Intracystic papillary carcinoma of the breast (IPC) is usually seen in postmenopausal elderly women. Its prognosis is much better than other type of breast tumors, and usually do not contain invasive components. Surgical excision with negative margins and axillary sentinel lymph node sampling is the recommended treatment. Two cases of intracystic papillary carcinoma of the breast that was treated at our clinic are herein presented. Both cases were postmenopausal, were both positive for estrogen and progesterone receptors and negative for HER 2. They underwent breast-conserving surgery. One patient had an invasive focus, therefore axillary lymph node sampling was performed, and the sentinel lymph node was not metastatic. This patient received hormonal therapy as well as radiotherapy. In the other case, there was no invasive focus and the surgical margins were negative, therefore, additional surgery was not performed. The patient is receiving hormonal therapy. Intracystic carcinoma of the breast should be kept in mind especially in elderly patients with breast cysts, with clinically or radiologically suspicious features, and biopsy and local excision should be considered. Although there is not any standard approach for patients with IPC, each patient must be evaluated for surgery and should be individually assessed in terms of adjuvant therapy.

RESUMEN

OBJECTIVE: General surgeons' approaches to breast masses in their daily practices and their perspectives for issues on breast diseases and breast surgery are investigated through a survey. MATERIALS AND METHODS: Answers of 524 general surgeons for the survey "Approach to breast diseases and breast surgery" between November 2012 and February 2013 were assessed. Demographic features, approaches to the breast masses, and answers for the clinical scenerios of surgeons were questioned. Surgeons were asked about management of breast cancer and the future role of surgeons for oncoplastic breast surgery and breast diseases. RESULTS: Participants were representing 14.6% of all general surgeons in Turkey. The survey revealed that breast diseases are the most common cause for admission in general surgery outpatient clinics. Needle biopsies were employed by 241 (60%) respondents. Three hundred and seventy-one (71%) participants indicated that breast cancer management could be accurately conducted by the general surgeons. Two hundred and seventy-three (52%) respondents think that oncoplastic breast surgery should be performed by a general surgeon and 241 (41%) respondents predict that the role of general surgeons for breast diseases and breast surgery will decrease in the future. CONCLUSION: Basic approaches towards breast masses need to be improved in our country despite the highest frequency of breast diseases in outpatient admissions. The views and opinions of surgeons on breast diseases and the course of breast surgery in different regions and different communities need to be defined and clarified.
