The role of next-generation sequencing in the examination of signaling genes in Brca1/2-negative breast cancer cases.

INTRODUCTION: Breast cancer is the most prevalent malignancy in women worldwide. Although pathogenic variants in the BRCA1/2 genes are responsible for the majority of hereditary breast cancer cases, a substantial proportion of patients are negative for pathogenic variations in these genes. In cancers, the signal transduction pathways of the cell are usually affected first. Therefore, this study aimed to detect and classified genetic variations in non-BRCA signaling genes and investigate the underlying genetic causes of susceptibility to breast cancer. METHODS: Ninety-six patients without pathogenic variants in the BRCA1/2 genes who met the inclusion criteria were enrolled in the study, and 34 genes were analyzed using next-generation sequencing (NGS) for genetic analysis. RESULTS: Based on the ClinVar database or American College of Medical Genetics criteria, a total of 55 variants of 16 genes were detected in 43 (44.8%) of the 96 patients included in the study. The pathogenic variants were found in the TP53, CHEK2, and RET genes, whereas the likely pathogenic variants were found in the FGFR1, FGFR3, EGFR, and NOTCH1 genes. CONCLUSION: The examination of signaling genes in patients who met the established criteria for hereditary breast cancer but were negative for BRCA1/2 pathogenic variants provided additional information for approximately 8% of the families. The results of the present study suggest that NGS is a powerful tool for investigating the underlying genetic causes of occurrence and progression of breast cancer.

The Effect of Residual Gastric Volume on Body Mass Index, Excess Weight Loss Rate and Metabolic Response after Sleeve Gastrectomy.

BACKGROUND/AIM: To investigate the metabolic response and body mass index reduction according to the remaining stomach volume between 6-12 months after the operation in patients who underwent sleeve gastrectomy surgery for obesity and to determine the relationship between the remaining stomach volume and metabolic improvement. Materials and Methods: Patients underwent sleeve gastrectomy in a single center by the same team and with the same standardized method. Residual gastric volumes were calculated from three-dimensional computed tomography images obtained 6-12 months postoperatively. BMI, excess weight loss (EWL), total cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL), very low density lipoprotein (VLDL), triglyceride, hemoglobin A1c (HbA1c), total protein, albumin values were recorded preoperatively and at the time of residual volume measurement. Results: There were 49 subjects with a mean SD preoperative BMI of 47.26+-6.21 kg/m2 and mean age 37.51+-10.88 years. Mean residual volume was 155.36+-56.71 cc. Residual volume was associated with postoperative mean BMI (28.44+-3.23 kg/m2; p 0.001) and postperative mean EWL%(29.27+-7.66; p=0.001). Residual gastric volume was also negative correlated with postoperative mean HbA1c (p=0.004). HbA1c (p=0.828), LDL (p=0.661), HDL (p=0.848), triglycerides (p=0.641), VLDL (p=0.794), total protein relation (p=0.539) and albumin (p=0.824) were analyzed before and after surgery and were not correlated with residual gastric volume. CONCLUSION: The smaller the residual gastric volume after laparoscopic sleeve gastrectomy, the higher the %EWL and the greater the decrease in HbA1c. This study show that laparoscopic sleeve gastrectomy is an effective surgical procedure in patients with Type 2 diabetes mellitus.

Proteomic analysis of thyroid tissue reveals enhanced catabolic activity in Graves' disease compared to toxic multinodular goitre.

Graves' disease (GD) and toxic multinodular goitre (TMNG) are the most common thyroid diseases which mainly lead to thyrotoxicosis, however, the underlying mechanism of distinct clinical presentations remains unclear. Protein extracts from the thyroid tissue specimens of the patients with GD and TMNG were subjected to Difference Gel Electrophoresis (DIGE). Differentially regulated protein spots were determined by image analysis, and the spots displaying statistically significant differences were identified by Matrix-Assisted Laser Desorption Ionization Time of Flight Mass Spectrometer (MALDI-TOF) followed by MASCOT search. Western blot analysis was used to verify changes occurring at the protein levels. The identified proteins were classified based on their functions in metabolic pathways using bioinformatics algorithms. Fifteen proteins showed significant alterations in abundance between the two disease groups. Bioinformatic analysis revealed the differentially regulated proteins were particularly related to catabolism, oxidative stress and especially energy utilization pathways, including glycolysis, proteolysis, ketone body catabolism and other energy metabolism-related pathways. SIGNIFICANCE OF THE STUDY: Previously, GD has been the subject of many studies that performed the proteomics approaches in the orbital tissue samples or tear. This is one of the very few studies that investigate the changes in the proteome of thyroid tissue in GD. We demonstrated mainly the upregulation of catabolic activity-related proteins in patients with GD compared to TMNG. Although it remains to be elucidated, some of these proteins can be used as markers for GD or have a role in the pathogenesis of the disease. Our study contributes the increasing data over time by providing new biomarker candidates for GD.

Cutaneous adverse effects of methylene blue in an animal skin-flap model.

Background and objectives: Sentinel lymph node biopsy is important for metastasis surveillance in the management of a number of human cancers. Identification of sentinel lymph nodes may be facilitated by the use of several methods including methylene blue injection. However tissue necrosis is a known effect of methylene blue application. This study aimed to investigate the effects of methylene blue injection on skin flaps using a rodent model.Methods: Modified McFarlane flaps were prepared using Wistar Albino rats. Local injection of methylene blue was given to one group while saline was injected into the control group. A third group received systemic methylene blue via intraperitoneal injection. Observational and histological comparison was made between the groups to investigate the necrotic effects of methylene blue on skip flaps.Results: The control group's surviving flap areas were significantly larger than local methylene blue group's surviving flap area. However, there was no significant difference in skin flap survival area between the control group and the systemic methylene blue group. Furthermore, there is no significant difference between local and systemic methylene blue group's surviving flap areas.Conclusions: Local methylene blue injection increases skin necrosis and decreases rates of surviving flap areas in an experimental rat models.

Improvement of Breast Cancer Patient Pathway Using EUSOMA Standards and European Guidelines.

Queues in hospitals are directly affecting the quality of human life, which should have priority compared to other types of queues. The aim of this paper is to design a future value stream map of the system and patient pathway in terms of quality improvement in order to decrease the non-value added activities for breast cancer patients, doctors and nurses for a radiology unit in a Training and Research University Hospital based in Kocaeli, Turkey. Nowadays, the increased demand versus insufficient sources affect healthcare services due to poor quality with long queues during the diagnosis and treatment processes. For this paper, data were collected from personal observations, information technologies units and authorized employees. Moreover, data tracking and keeping systems are too poor for revealing the current situation. This paper provides an example of a current and future value stream map showing step by step where the bottlenecks are and how it can be improved and what specific benefits it will bring to the healthcare system. In consideration of all these outcomes, it is highly suggested that the hospital apply European Guidelines for quality assurance in breast cancer screening and diagnosis together with the mentioned above improvement suggestions using lean applications.

Elucidation of a Conserved Proteomic Pattern of Breast Cancer Tissue and Metastatic Axillary Lymph Node.

OBJECTIVE: Breast cancer is one of the most devastating cancer types affecting women. For critical decision making regarding the fate of cancerous breast tissue, the assessment of axillary lymph node (ALN) involvement is required. However, such ALN involvement is difficult to predict without surgical intervention. Therefore, an easy predictive test using protein markers may be a desirable approach. In this study, we performed a whole proteome analysis to reveal the presence of a putative biomarker panel using primary breast tumor tissue. Materials and Methods: Proteins were extracted from tumor tissues and were subjected to two dimensional (2D) gel electrophoresis. The resulting gel images were used for inter-gel spot comparisons using PDQuest Advance software. The paterns thus obtained were used for differentiating invasive tumor types from non-invasive ones. Results: The analysis of 2D gel images revealed the presence of 24 conserved protein spots whose intensities were moderately regulated high on the gels. Those protein spots were used to create a conserved 2D pattern spanning a pH range of 4 to 8. CONCLUSION: Protein spots generating a preserved model among pattern between primary breast cancer and its axillary lymph node indicated that a robust and highly reliable proteomic approach, e.g., 2DE may be used to differentiate metastatic forms of breast cancer from non-metastatic ones.

Factors affecting breast cancer treatment delay in Turkey: a study from Turkish Federation of Breast Diseases Societies.

BACKGROUND: One of the most important factors in breast cancer (BC) mortality is treatment delay. The primary goal of this survey was to identify factors affecting the total delay time (TDT) in Turkish BC patients. METHODS: A total of 1031 patients with BC were surveyed using a uniform questionnaire. The time between discovering the first symptom and signing up for the first medical visit (patient delay time; PDT) and the time between the first medical visit and the start of therapy (system delay time; SDT) were modelled separately with multilevel regression. RESULTS: The mean PDT, SDT and TDT were 4.8, 10.5 and 13.8 weeks, respectively. In all, 42% of the patients had a TDT >12 weeks. Longer PDT was significantly correlated with disregarding symptoms and having age of between 30 and 39 years. Shorter PDT was characteristic of patients who: had stronger self-examination habits, received more support from family and friends and had at least secondary education. Predictors of longer SDT included disregard of symptoms, distrust in success of therapy and medical system and having PDT in excess of 4 weeks. Shorter SDT was linked to the age of >60 years. Patients who were diagnosed during a periodic check-up or opportunistic mammography displayed shorter SDT compared with those who had symptomatic BC and their first medical examination was by a surgeon. CONCLUSION: TDT in Turkey is long and remains a major problem. Delays can be reduced by increasing BC awareness, implementing organized population-based screening programmes and founding cancer centres.

Bilobar thyroid agenesis with primary hyperparathyroidism: report of a case.

Congenital thyroid abnormalities are rarely seen. They mostly include hemiagenesis with or without involving the isthmus. In this report, we present a case of bilateral lobe agenesis with hypertrophied isthmus and high calcium and elevated PTH levels which were detected during routine examinations of a 49-year-old female patient. Some findings consistent with parathyroid pathology on the right side were determined in parathyroid scintigraphy. At thyroid scan and neck ultrasonography there was no sign of bilateral thyroid tissue except a mass localized isthmus. The right lower parathyroidectomy and thyroidectomy for isthmus were performed; the pathology report was shown as parathyroid adenoma and nodular colloidal goiter. This case of bilobar agenesis with incidental primary hyperparathyroidism due to single parathyroid adenoma is the first case reported in literature.

Evaluation of relationship between serum lipids levels with colorectal carcinoma: a single center prospective case control study.

BACKGROUND/AIMS: To evaluate association of serum lipids and fasting plasma glucose levels with colorectal cancer. METHODOLOGY: This prospective case control study was conducted with 347 patients with colorectal carcinoma and 310 age and gender matched healthy controls who were examined for annual check-up. Total cholesterol, serum lipids and fasting glucose levels were measured in both groups. Body weight and body mass indices were also evaluated. RESULTS: The mean serum cholesterol level was 167.4 +/- 43.6 mg/dL for patients with colorectal cancer and 210.1 +/- 30.7 mg/dL for controls. The mean fasting plasma glucose levels for both groups were respectively 107.7 +/- 22.4 and 90.2 +/- 10.3. Between the colorectal cancer and control groups, there was a statistically significant difference in fasting plasma glucose and serum lipid levels except LDL-C. Serum total cholesterol level was even lower in advanced stages of cancer. CONCLUSIONS: Our study suggests that there is an inverse association between low serum total cholesterol levels and colorectal cancer. Since cholesterol levels were lower in the advanced stages of colorectal cancer it is possible that low levels of serum cholesterol levels were a consequence of colorectal cancer. The association with hypertriglyceridemia and high fasting plasma glucose levels suggest the role of hyperinsulinemia in colorectal carcinogenesis.

Serum cytokine levels in patients with colorectal cancers according to tumor stages and VEGF gene polymorphism.

BACKGROUND/AIMS: Colorectal cancers are the most common cancers of the gastrointestinal system. A significant relationship was detected between the metastasis and tumor angiogenesis of colorectal cancer. The aim of the present study was to investigate the association between some cytokines and tumor stages. Additionally, association between VEGF gene polymorphisms and colorectal cancer was studied. METHODS: In this study, we measured serum IL-18, IL-2, VEGF, endothelin (ET), and nitric oxide (NO) levels in 44 patients with colorectal cancer and 44 healthy controls. Also we investigated VEGF G634C (rs2010963) and VEGF C936T (rs3025039) polymorphisms of VEGF gene in these groups by using a PCR-RFLP method. Data were analyzed statistically. RESULTS: Serum levels of IL-18, VEGF, IL-2 and NO were significantly higher in patients with colorectal cancer when compared to controls (p<0,05). Serum ET levels were found to be similar in colorectal cancer patients and healthy controls. When we compared the two subgroups constituted by tumor stages (Stage 1-2 and Stage 3-4) with each other, serum VEGF levels were found significantly higher in stage 3-4 group than stage 1-2 group (p<0,05). No significant difference was found between subgroups with regard to other parameters. We found that investigated VEGF G634C and VEGF C936T polymorphisms were not associated with the severity of colorectal cancer. (P=0.228 for VEGF G­634-C; P= 0.484 for VEGF C­936-T) CONCLUSION: In the future, serum levels of IL-18, VEGF, IL-2 and NO may be a useful marker for diagnosis of patients with colorectal cancer. Additionally we consider that serum VEGF levels can be used as a tumor marker to predict prognosis of cancer. However, larger studies with long-term follow-up are necessary to clarify this hypothesis. On the other hand, there is necessity for the new studies for determination of association between VEGF gene polymorphism and colorectal cancer.

The emerging role of national academies in surgical training: an inspiring environment for increasing the quality of health care in breast cancer management.

Medical education, both graduate and postgraduate, is given at medical schools and affiliated teaching hospitals. The training at these institutions is necessary and valuable. In each field of the medical profession, the relevant science is being developed and changed constantly. Training of medical staff and auxilliary professionals must be adaptable to changes in the field. Also, the development of standards for the diagnosis and treatment of diseases is important. Independent institutions, called academies, serve an extremely useful task in the continuing further training that needs to be adjusted according to individual needs. Academies are independent and free from bureaucracies. Standardized records are uniform and comparable at these institutions. Both patients and medical staff receive training from these institutions. In this way, a high standard is provided in medicine, error rates are decreased and patient satisfaction is increased. Breast cancer, the most common tumor in women, is a serious cause of morbidity and mortality. The European Institute of Oncology (EIO) in Milan, Italy and the European Academy of Senology in Duesseldorf, Germany play important roles in establishing the standards of breast care. They provide substantial training for physicians to achieve high quality in breast cancer management. SENATURK (Senoloji Akademisi, Turkish Academy of Senology) was established in 2010 in Istanbul, Turkey. Both national and international scientists and physicians including eminent senologists are currently faculty members of this young organization. SENATURK collaborates with other institutions in Europe. Its missions include developing training programs for each level of the profession, as well as developing data recording systems and electronic learning tools for breast cancer prevention, diagnosis, treatment, rehabilitation and palliation. Briefly, SENATURK plays a significant role as the opinion leader on every aspect of health care related to conditions and diseases of the breast.

Response to trauma and metabolic changes: posttraumatic metabolism.

Stress response caused by events such as surgical trauma includes endocrine, metabolic and immunological changes. Stress hormones and cytokines play a role in these reactions. More reactions are induced by greater stress, ultimately leading to greater catabolic effects. Cuthbertson reported the characteristic response that occurs in trauma patients: protein and fat consumption and protection of body fluids and electrolytes because of hypermetabolism in the early period. The oxygen and energy requirement increases in proportion to the severity of trauma. The awareness of alterations in amino acid, lipid, and carbohydrate metabolism changes in surgical patients is important in determining metabolic and nutritional support. The main metabolic change in response to injury that leads to a series of reactions is the reduction of the normal anabolic effect of insulin, i.e. the development of insulin resistance. Free fatty acids are primary sources of energy after trauma. Triglycerides meet 50 to 80 % of the consumed energy after trauma and in critical illness. Surgical stress and trauma result in a reduction in protein synthesis and moderate protein degradation. Severe trauma, burns and sepsis result in increased protein degradation. The aim of glucose administration to surgical patients during fasting is to reduce proteolysis and to prevent loss of muscle mass. In major stress such as sepsis and trauma, it is important both to reduce the catabolic response that is the key to faster healing after surgery and to obtain a balanced metabolism in the shortest possible time with minimum loss. For these reasons, the details of metabolic response to trauma should be known in managing these situations and patients should be treated accordingly.

Downregulated GPD1 and MAGL protein levels as potential biomarkers for the metastasis of triple­negative breast tumors to axillary lymph nodes.

Glycerol-3-phosphate dehydrogenase (GPD1) and monoacylglycerol lipase (MAGL) levels are known to be significantly downregulated in both the tissue and serum samples of patients with triple-negative breast cancer (TNBC), compared with other BC subtypes and healthy controls. As such, the association between GPD1 and MAGL levels and lymph node metastasis was evaluated in the present study. Utilizing western blotting, lymph node protein extracts from metastasized BC subtypes were analyzed and a significant downregulation of GPD1 and MAGL protein expression levels in the lymph node metastases was demonstrated in the TNBC subtype, compared with healthy controls. This finding further highlighted the potential use of these two proteins in early BC onset and metastasis detection.

Utility of positron emission tomography for determination of axillary metastasis of breast cancer.

Objectives: The involvement of axillary lymph nodes plays a key role in breast cancer staging. Positron emission tomography is a promising modality for detecting axillary lymph node metastasis. In addition, nomograms are used to predict the status of axillary lymph nodes. In this study, the role of positron emission tomography in determining axillary metastasis and its correlation with the nomogram was evaluated. Material and Methods: The axillary maximum standard uptake value (SUVmax) values of the patients in the preoperative period, the features in the perioperative and postoperative specimen and Memorial Sloan Kettering Cancer Center nomogram data were evaluated. Results: As axillary SUVmax detected by Positron emission tomography in the preoperative period increased, so did the likelihood of lymph node involvement. Axillary SUVmax value were compared with Memorial Sloan Kettering Cancer Center nomogram data but no correlation was found. Age, lymph node number, histopathology results, mass diameter, presence or absence of lymphovascular invasion and/or perineural invasion, tumor type, estrogen receptor status, Ki67 and Cerb-B2 statuses were not correlated. However, axillary SUVmax was inversely correlated with grade and progesterone receptor status. Conclusion: Results from positron emission tomography of axillary lymph nodes in breasts cancer patients showed that SUVmax was only inversely related to cancer grade and progesterone receptor status while not correlating with other accepted parameters for tumor assessment. Thus there is insufficient reliability for the use of axillary SUVmax alone for accurate assessment of tumor characteristics at present.

Localization Techniques for Non-Palpable Breast Lesions: Current Status, Knowledge Gaps, and Rationale for the MELODY Study (EUBREAST-4/iBRA-NET, NCT 05559411).

BACKGROUND: Surgical excision of a non-palpable breast lesion requires a localization step. Among available techniques, wire-guided localization (WGL) is most commonly used. Other techniques (radioactive, magnetic, radar or radiofrequency-based, and intraoperative ultrasound) have been developed in the last two decades with the aim of improving outcomes and logistics. METHODS: We performed a systematic review on localization techniques for non-palpable breast cancer. RESULTS: For most techniques, oncological outcomes such as lesion identification and clear margin rate seem either comparable with or better than for WGL, but evidence is limited to small cohort studies for some of the devices. Intraoperative ultrasound is associated with significantly higher negative margin rates in meta-analyses of randomized clinical trials (RCTs). Radioactive techniques were studied in several RCTs and are non-inferior to WGL. Smaller studies show higher patient preference towards wire-free localization, but little is known about surgeons' and radiologists' attitudes towards these techniques. CONCLUSIONS: Large studies with an additional focus on patient, surgeon, and radiologist preference are necessary. This review aims to present the rationale for the MELODY (NCT05559411) study and to enable standardization of outcome measures for future studies.

An Atypical Presentation of Hydatid Disease, Accompanied by a Pancreatic Pseudocyst: A Case Report.

Hydatid disease (HD) is a zoonotic disease, which typically affects the liver and the lungs. Primary retroperitoneal localization of the disease is infrequent. The most common symptom is abdominal pain; however, the clinical features of HD may be generally dependent on the location of the cyst. A 53-year-old female patient presented to Kocaeli University General Surgery Clinic, Turkey in September 2019 with complaints of flank pain, constipation and vomiting. The MRI revealed cystic lesions in the pancreas and psoas muscle. Both cysts were excised totally during laparotomy. Histopathology reports showed that the lesion in psoas muscle was hydatid cyst whereas the lesion in pancreas was pancreatic pseudocyst. Postoperative period was uneventful and the patient was discharged with albendazole treatment. No recurrence occurred during follow-up period. Atypical localization for hydatid disease is a diagnostic dilemma for surgeons, especially in endemic countries. Hydatid disease should always be considered in the differential diagnosis of retroperitoneal lesions, inadequate management can lead to complications and fatalities. Surgery combined with antiparasitic therapy, may be an option in the presence of obstruction of gastrointestinal and/or urinary tract.

Tissue proteome analysis revealed an association between cancer, immune system response, and the idiopathic granulomatous mastitis.

Idiopathic Granulomatous Mastitis (IGM) is a disease that clinically mimics breast cancers with symptoms of pain, edema, erythema, nipple discharge, nipple retraction, and fistula. Although IGM is considered to be formed by autoimmune responses or infections, the molecular mechanism behind formation and progress is unknown. Therefore, in this study, we aimed to investigate molecular mechanisms underlying IGM formation, progress, and recurrence by monitoring the changes at the proteome level. Protein extracts prepared from IGM (n = 15) and within-control tissues (n = 15) were subjected to nHPLC followed by LC-MS/MS proteomic analysis. Label-free quantitation analysis revealed that sixty differentially regulated between the two groups. Those proteins were classified based on their role in metabolic pathways using bioinformatics tools. Based on DAVID analysis, 16 of the differently regulated proteins were associated with the immune system, while 17 proteins were involved in cancer metabolism. STRING analysis showed that five of the differentially regulated proteins were associated with combined immune deficiency which were PNP, TAP1, ITGAL, PRKDC, and PTPRC while the other proteins were involved in insulin response and neutrophil degranulation. This study is one of the very few studies that investigated the changes in protein expressions of IGM tissues compared to controls. For the first time, we have shown the relationship of IGM with the immune system at the protein level and also underlined the cancer-like behavior of the disease. Furthermore, the proteins that were pointed out as combined immune deficiency-related proteins may have value as diagnostic markers for idiopathic granulomatous mastitis although further studies are needed to shed more light on the pathogenesis of the disease.

Management of endocrine surgical disorders during COVID-19 pandemic: expert opinion for non-surgical options.

PURPOSE: The COVID-19 pandemic brought unprecedented conditions for overall health care systems by restricting resources for non-COVID-19 patients. As the burden of the disease escalates, routine elective surgeries are being cancelled. The aim of this paper was to provide a guideline for management of endocrine surgical disorders during a pandemic. METHODS: We used Delphi method with a nine-scale Likert scale on two rounds of voting involving 64 experienced eminent surgeons and endocrinologists who had the necessary experience to provide insight on endocrine disorder management. All voting was done by email using a standard questionnaire. RESULTS: Overall, 37 recommendations were voted on. In two rounds, all recommendations reached an agreement and were either endorsed or rejected. Endorsed statements include dietary change in primary hyperparathyroidism, Cinacalcet treatment in secondary hyperparathyroidism, alpha-blocker administration for pheochromocytoma, methimazole ± ß-blocker combination for Graves' disease, and follow-up for fine-needle aspiration results of thyroid nodules indicated as Bethesda 3-4 cytological results and papillary microcarcinoma. CONCLUSION: This survey summarizes expert opinion for the management of endocrine surgical conditions during unprecedented times when access to surgical treatment is severely disrupted. The statements are not applicable in circumstances in which surgical treatment is possible.

Value-Based Quality Care for Breast Cancer: More Than Guidelines.

Although guidelines recommend some of the most expensive diagnostic methods and therapies, some patients do have the opportunity to use them, but some others have overused or misused such methods. The cost of cancer care is increasing, but the satisfaction levels of patients and healthcare workers have not increased in line with this rise. Value-based care for cancer, especially breast cancer, should be implemented. For this reason, all unnecessary screening, tests, treatments, and follow-up parameters should be avoided.

Oncoplastic Breast-Conserving Surgery According to Tumor Location.

The use of oncoplastic breast surgery is an essential cornerstone for breast cancer management. The main aim of breast cancer surgery is to obtain an adequate oncological safety margin. Still, the cosmetic outcome also seems important for social and psychological wellbeing and quality of life. After breast-conserving surgery, the remaining breast may be reconstructed with volume displacement or volume replacement techniques. A better cosmetic outcome can be achieved by selecting appropriate surgical techniques according to tumor location. In this review, we show each technique step-by-step based on the tumor's location for each quadrant. The most important thing is to select the technique first for oncological safety and then for better cosmesis.
