ABSTRACT

In this editorial, the authors bring to the attention of surgeons a personal point of view with the intention of offering a series of anatomical arguments to explain the high rate of functional complications following ultralow rectal resections, resections dominated by faecal incontinence of various intensities. Having as a starting point the anatomy of the pelvic floor and the posterior perineum, the authors are concerned with the functional outcomes of the sphincter-saving anterior rectal resection, regarding the low and ultralow resection. Technically, a conservative surgery for low rectal cancer has been currently performed. If 25 years ago the abdominoperineal resection was the gold standard for rectal cancer located under 7cm from the anal verge, nowadays the preservation of the anal canal as a partner for colon anastomosis has been accomplished. Progressively, from a desire to preserve the normal passage of stool into the anal canal, as anatomically and physiologically as possible, the distal limit of resection was lowered to 2-4 cm from the anal verge and ultra-low anastomoses were created, within the anal sphincter complex. The stated goal: keep the oncological safety standard and, at the same time, avoid definitive colostomy. Starting from the normal anatomy of the pelvic floor and the anorectal segment, the authors take a look at the alterations of the visceral, muscular, and nerve structures as a consequence of the low anterior resection and, particularly, the ultralow anterior resection. A significant degree of functional outcomes regarding defecation, with the onset of marked disabilities of anal continence, the major consequence being anal incontinence (30-70%), have been noticed. The authors go under review for the main anatomical and physiological changes that accompany anterior rectal resection. Conclusions: Thus, the following questions arise: what is the lower limit of resection to avoid total fecal incontinence? Is total incontinence a greater handicap than colostomy or is it not? The answers cannot be supported by solid arguments at this time, but the need to initiate future studies dedicated to this problem emerges.

ABSTRACT

Cervical cancer continues to be a public health concern, as it remains the second most common cancer despite screening programs. It is the third most common cause of cancer-related death for women, and the majority of cases happen in developing nations. The standard treatment for locally advanced cervical cancer involves the use of external beam radiation therapy, along with concurrent chemotherapy, followed by an image-guided adaptive brachytherapy (IGABT) boost. The five-year relative survival rate for European women diagnosed with cervical cancer was 62% between 2000 and 2007. Updated cervical cancer treatment guidelines based on IGABT have been developed by the Gynecological working group, which is composed of the Group Européen de Curiethérapie-European Society for Therapeutic Radiology and Oncology. The therapeutic strategy makes use of three-dimensional imaging, which can be tailored to the target volume and at-risk organs through the use of computed tomography or magnetic resonance imaging. Under anaesthesia, the brachytherapy implantation is carried out. Ultrasonography is utilised to assess the depth of the uterine cavity and to facilitate the dilation of the uterine canal during the application insertion. In this study, we examine data from the international literature regarding the application of ultrasound in cervical cancer brachytherapy.

ABSTRACT

BACKGROUND: Pseudomyxoma peritonei (PMP) is a rare, progressive, slowly growing, inadequately understood neoplasm with a 5-year progression-free survival rate of as low as 48%. It is characterized by varying degrees of malignancy and the production of mucinous and gelatinous structures. Typically, the development of pseudomyxoma peritonei is associated with the rupture of appendiceal mucinous tumors and other gastrointestinal or ovarian mucinous tumors. The goal of our literature review was to identify various aspects that characterize the ovarian causes of pseudomyxoma peritonei. MATERIALS AND METHODS: The authors performed an extensive literature search between 1 February 2024 and 2 March 2024 on the following databases: Pubmed, Scopus, Oxford Journals, and Reaxys, and the findings were summarized into seven main clinical and paraclinical situations. RESULTS: According to our research, the main instances in which pseudomyxoma peritonei can be triggered by an ovarian cause are the following: (1) mucinous cystadenoma; (2) mucinous ovarian cancer; (3) colon cancer with ovarian metastasis; (4) malignant transformation of an ovarian primary mature cystic teratoma; (5) appendiceal mucocele with peritoneal dissemination mimicking an ovarian tumor with peritoneal carcinomatosis; (6) mucinous borderline tumor developing inside an ovarian teratoma; and (7) the association between a mucinous bilateral ovarian cancer and a colonic tumor. CONCLUSIONS: In our study, we aimed to provide a comprehensive overview of the ovarian causes of pseudomyxoma peritonei, including its epidemiology, imagery characteristics, symptoms, current treatment, and promising future therapies, in the hopes of finding feasible solutions, as a lack of understanding of this mucus-secreting malignant disease increases the risk of delayed diagnosis or uncontrolled deterioration.

ABSTRACT

Laparoscopic cholecystectomy (LC) is the gold standard treatment in acute cholecystitis. However, one in six cases is expected to be difficult due to intense inflammation and suspected adherence to and involvement of adjacent important structures, which may predispose patients to higher risk of vascular and biliary injuries. In this study, we aimed to identify the preoperative parameters with predictive value for surgical difficulties. A retrospective study of 255 patients with acute cholecystitis admitted in emergency was performed between 2019 and 2023. Patients in the difficult laparoscopic cholecystectomy (DLC) group experienced more complications compared to the normal LC group (33.3% vs. 15.3%, p < 0.001). Age (p = 0.009), male sex (p = 0.03), diabetes (p = 0.02), delayed presentation (p = 0.03), fever (p = 0.004), and a positive Murphy sign (p = 0.007) were more frequently encountered in the DLC group. Total leukocytes, neutrophils, and the neutrophil-to-lymphocyte ratio (NLR) were significantly higher in the DLC group (p < 0.001, p = 0.001, p = 0.001 respectively). The Tongyoo score (AUC ROC of 0.856) and a multivariate model based on serum fibrinogen, thickness of the gallbladder wall, and transverse diameter of the gallbladder (AUC ROC of 0.802) showed a superior predictive power when compared to independent parameters. The predictive factors for DLC should be assessed preoperatively to optimize the therapeutic decision.

ABSTRACT

The incidence and mortality of cervical cancer are high in Romania compared to other European countries, particularly for locally advanced cervical cancer cases, which are predominant at the time of diagnosis. Widely accepted therapeutic guidelines indicate that the treatment for locally advanced cervical cancer consists of concurrent chemoradiotherapy (total dose 85-90 Gy at point A), with surgery not being necessary as it does not lead to improved survival and results in significant additional morbidity. In Romania, the treatment for locally advanced cervical cancer differs, involving lower-dose chemoradiotherapy (total dose 60-65 Gy at point A), followed by surgery, which, under these circumstances, ensures better local control. In this regard, we attempted to evaluate the role and necessity of surgery in Romania, considering that in our study, residual lesions were found in 55.84% of cases on resected specimens, especially in cases with unfavorable histology (adenocarcinoma and adenosquamous carcinoma). This type of surgery was associated with significant morbidity (28.22%) in our study. The recurrence rate was 24.21% for operated-on patients compared to 62% for non-operated-on patients receiving suboptimal concurrent chemotherapy alone. In conclusion, in Romania, surgery will continue to play a predominant role until radiotherapy achieves the desired effectiveness for local control.

ABSTRACT

(1) Importance of problem: Breast cancer accounted for 685,000 deaths globally in 2020, and half of all cases occur in women with no specific risk factor besides gender and age group. During the last four decades, we have seen a 40% reduction in age-standardized breast cancer mortality and have also witnessed a reduction in the medium age at diagnosis, which in turn means that the number of mastectomies performed for younger women increased, raising the need for adequate breast reconstructive surgery. Advances in oncological treatment have made it possible to limit the extent of what represents radical surgery for breast cancer, yet in the past decade, we have seen a marked trend toward mastectomies in breast-conserving surgery-eligible patients. Prophylactic mastectomies have also registered an upward trend. This trend together with new uses for breast reconstruction like chest feminization in transgender patients has increased the need for breast reconstruction surgery. (2) Purpose: The purpose of this study is to analyze the types of reconstructive procedures, their indications, their limitations, their functional results, and their safety profiles when used during the integrated treatment plan of the oncologic patient. (3) Methods: We conducted an extensive literature review of the main reconstructive techniques, especially the autologous procedures; summarized the findings; and presented a few cases from our own experience for exemplification of the usage of breast reconstruction in oncologic patients. (4) Conclusions: Breast reconstruction has become a necessary step in the treatment of most breast cancers, and many reconstructive techniques are now routinely practiced. Microsurgical techniques are considered the "gold standard", but they are not accessible to all services, from a technical or financial point of view, so pediculated flaps remain the safe and reliable option, along with alloplastic procedures, to improve the quality of life of these patients.

ABSTRACT

The literature review is a direct consequence of the increased volume of scientific information, becoming a necessity not only for the medical field. Such material, properly done, is of great use to any professional who wishes to keep abreast of the latest knowledge and concepts. The proposed goal is to help and guide resident doctors, doctoral students, and young researchers in understanding the concepts that are the basis of conducting a literature review and acquiring the generally accepted methodology for conducting it. The selection of information sources, accessing databases, the concept of peer-review, indexing and the impact factor are clearly presented as elements that cannot be neglected in the valorisation of scientific information sources. The structure of a literature review must consider the generally accepted format for such an article, with each chapter having its own importance. Depending on the quality and heterogeneity of the results obtained after analysing the collected data, the review can be structured narratively or systematically, the homogeneity of the results allowing the application of statistical study methods (meta-analysis). Although it seems difficult, conducting a literature review is easier and faster than developing an original study based on experimental or clinical scientific research. The literature review can be carried out in comfortable conditions, online, regardless of location and is a welcome support in the development of the professional and scientific career.

ABSTRACT

(1) Introduction: A Romanian woman is diagnosed with cervical cancer every two hours; the country ranks second in Europe in terms of the mortality and incidence rate of this disease. This paper aims to identify the main reasons that have led to this situation, focusing on the measures taken by the Romanian Ministry of Health for the prevention of this type of cancer-national programs for cervical cancer screening and HPV vaccination. (2) Materials and methods: We performed a study based on the available secondary data from the National Statistics Institute, World Health Organization and Bucharest Institute of Oncology in order to assess the burden associated with cervical cancer and place it in the context of known global and European incidence and mortality rates, thus evaluating the importance of this health issue in Romania. The second component of our study was a cross-sectional study. Here, we used a 14-question questionnaire applied to the women participating in the National Screening Program for Cervical Cancer and aimed to evaluate the women's level of knowledge about screening and HPV vaccination and their access cervical-cancer-specific healthcare services. (3) Results: The results of this research show that a high percentage of women postpone routine checks due to a lack of time and financial resources and indicate that a low level of knowledge about the disease and the specific preventive methods determines the low participation in screening and HPV vaccination programs implemented in Romania, contributing to the country's cervical cancer situation. (4) Conclusions: The national programs have complicated procedures, are underfunded and do not motivate healthcare workers enough. This, combined with the lack of information for the eligible population, adds up to an extremely low number of women screened and vaccinated. Our conclusion is that the Romanian Ministry of Health must take immediate action by conducting major awareness campaigns, implementing measures to make the programs functional and ensuring coherent funding.

ABSTRACT

Introduction: Cholelithiasis still remains one of the most frequent pathologies encountered in surgical practice. The authors review the stages which marked the evolution of the treatment of choledochal lithiasis (CL) during the last 50 years, based on their own experience. From the exclusively surgical choledochus, we have reached a multidisciplinary therapy in which both endoscopy and interventional radiology have found their place. Material and Method: The authors studied 2 groups of patients: Group 1 included patients from the period 1959-1997 (38 years - 982 cases of choledocholithiasis) who underwent classical surgery. Group 2 included patients treated between 1997-2017 (20 years â?" 347 cases) in whom both endoscopic surgery and classic surgery were used to obtain choledochal clearance. The types of choledochal lithiasis (CL) according to which the method of obstruction clearance was decided upon and chosen are presented here. Results: All the patients in group 1 underwent classical surgery, representing 9.8% of operations for biliary lithiasis. In group 2, classical surgery was recorded in 23.4% of patients, and endoscopic surgery in 76.6% of them. We mention that there was no laparoscopic approach for the treatment of CL due to the absence of experience. In group 2 we recorded 26.3% endoscopic failure, while in the classical approach group there was 12.3% failure of obstruction clearance, the solution being biliodigestive anastomoses. Conclusions: The authors propose three categories of therapeutic indications in CL. A first category is represented by the "endoscopic choledochus", which includes migrated lithiasis. A second category is the "surgical choledocus". It is the situation of complex and complicated lithiases. Finally, there would be a third category - the "lithogenic choledocus". This last group includes the most aggressive lithiases with repeated relapses, panlithiases, etc. For categories 2 and 3, endoscopic - laparoscopic clearance attempts have no chance of success or are even contraindicated.

ABSTRACT

Background: Due to its many benefits, indocyanine green (ICG) has gained progressive popularity in operating rooms (ORs) globally. This literature review examines its qualitative and quantitative usage in surgical treatment. Method: Relevant terms were searched in five international databases (1. Pubmed, 2. Sciencedirect, 3. Scopus, 4. Oxfordjournals, 5. Reaxys) for a comprehensive literature review. The main benefits of using ICG in colorectal surgery are: intraoperative fluorescence angiography; fluorescence-guided lymph node involvement detection and the sentinel technique; the fluorescent emphasis of a minute liver tumour, counting just 200 tumour cells; facilitation of fistula diagnosis; and tumour tattooing. This methodology can also be used with quantitative characteristics such as maximum intensity, relative maximum intensity, and in-flow parameters such as time-to-peak, slope, and t1/2max. This article concludes that fluorescence surgery with ICG and near-infrared (NIR) light is a relatively new technology that improves anatomical and functional information, allowing more comprehensive and safer tumour removal and the preservation of important structures.

ABSTRACT

Introduction: Management of synchronous colorectal cancer with liver metastases (SCLM) is still on debate, regarding timing, indications and complications of the 3 strategies: classic approach (first tumor resection), simultaneous resection and reverse approach (liver first). A retrospective single-centre evaluation of synchronous approach was accomplished, focusing on surgical technique, indications and complications. Material and Methods: Between 2017 and 2020, 31 SCLM patients benefited from synchronously colorectal and hepatic approach: segmental colectomies/rectal resections, simultaneously with liver metastasectomies (associated with radiofrequency ablation). Post-therapeutic imaging monitoring was performed from every 3 - 6 months. There were no perioperative complications related to the combination of the procedures, low morbidity and zero postoperative mortality. Results: The follow-up period was 10 - 40 months: 13 patients had no evidence of recurrence, 10 had hepatic metastases in regression, 4 patients had signs of peritoneal carcinomatosis and 4 showed progression of liver disease; all patients were on chemotherapy. During follow-up 4 patients died. Conclusions: Experience shows that the simultaneous approach of recto-colic and hepatic resections in colo-rectal cancers is a safe procedure, with low morbidity, the limits being dictated by the size of the liver metastases. The results at long-distance must be drawn by further consistent trials.

ABSTRACT

The aim of our study is to present the particularities of a specific subset of gynecological cancer patients in Romania. We present a review of synchronous gynecological neoplasia (SGN) treated in the Bucharest Oncological Institute's surgery departments over a decade. Between 2012 and 2022, 7419 female patients with genital malignancies were treated. We identified 36 patients with invasive synchronous primary gynecological cancers (0.5%) and 12 cases with one primary gynecological and another primary invasive pelvic cancer (rectal/bladder). All recurrent, metastatic, or metachronous tumors detected were excluded. Demographic data, personal history, presenting symptoms, pathologic findings, staging, treatment, and evolution for each case were recorded. Usually, the most common SGN association is between ovarian and endometrial cancer of endometrioid differentiation (low-grade malignancies with very good prognosis). However, we noticed that, given the particularities of the Romanian medical system, the most frequent association is between cervical and endometrial, followed by cervical and ovarian cancers. Moreover, the cancer stage at diagnosis is more advanced. In countries with low HPV vaccination rate and low adherence to screening programs, SGNs can present as extremely advanced cases and require extensive surgery (such as pelvic exenterations) to achieve radicality. This multimodal treatment in advanced cases with high tumor burden determines a reduction in survival, time until progression, and quality of life.

ABSTRACT

(1) Background: Salvation surgery for small-cell lung cancer (SCLC) is exceptionally performed, and only a few cases are published. (2) Methods: There are 6 publications that present 17 cases of salvation surgery for SCLC-the salvation surgery was performed in the context of modern clearly established protocols for SCLC and after including SCLC in the TNM (tumor, node, metastasis) staging in 2010. (3) Results: After a median follow-up of 29 months, the estimated overall survival (OS) was 86 months. The median estimated 2-year survival was 92%, and the median estimated 5-year survival was 66%. (4) Conclusion: Salvage surgery for SCLC is a relatively new and extremely uncommon concept and represents an alternative to second-line chemotherapy. It is valuable because it may offer a reasonable treatment for selected patients, good local control, and a favorable survival outcome.

ABSTRACT

(1) Background: Among new anti-angiogenesis agents being developed and ever-changing guidelines indications, the question of the benefits/safety ratio remains unclear. (2) Methods: We performed a systematic review combined with a meta-analysis of 23 randomized controlled trials (12,081 patients), evaluating overall survival (OS), progression free survival (PFS) and toxicity (grade ≥ 3 toxic effects, type, and number of all adverse effects. (3) Results: The analysis showed improvement of pooled-PFS (HR, 0.71; 95% CI, 0.64-0.78; I2 = 77%; p < 0.00001) in first-line (HR, 0.85; 95% CI, 0.78-0.93; p = 0.0003) or recurrent cancer (HR, 0.62; 95% CI, 0.56-0.70; p < 0.00001) and regardless of the type of anti-angiogenesis drug used (Vascular endothelial growth factor (VEGF) inhibitors, VEGF-receptors (VEGF-R) inhibitors or angiopoietin inhibitors). Improved OS was also observed (HR, 0.95; 95% CI, 0.90-0.99; p = 0.03). OS benefits were only observed in recurrent neoplasms, both platinum-sensitive and platinum-resistant neoplasms. Grade ≥ 3 adverse effects were increased across all trials. Anti-angiogenetic therapy increased the risk of hypertension, infection, thromboembolic/hemorrhagic events, and gastro-intestinal perforations but not the risk of wound-related issues, anemia or posterior leukoencephalopathy syndrome. (4) Conclusions: Although angiogenesis inhibitors improve PFS, there are little-to-no OS benefits. Given the high risk of severe adverse reactions, a careful selection of patients is required for obtaining the best results possible.

ABSTRACT

(1) Background: The aim of our study was to assess the feasibility of 99mTcEDDA/HYNIC-TOC SPECT/CT quantitative analysis in evaluating treatment response and disease progression in patients with NETs. (2) Methods: This prospective monocentric study evaluated 35 SPECT/CT examinations performed on 14 patients with neuroendocrine tumours who underwent a baseline and at least one follow-up 99mTcEDDA/HYNIC-TOC scan as part of their clinical management. The examination protocol included a whole-body scan acquired 2 h after the radiotracer's administration, with the SPECT/CT performed 4 h post-injection. Images were analyzed by two experienced physicians and patients were classified into response categories based on their changes in SUV values. (3) Results: We evaluated 14 baseline studies and 21 follow-up scans, accounting for 123 lesions. A statistically positive correlation has been found between the SUVmax and SUVpeak values in tumoral lesions (p < 0.05). No correlation has been found between the SUV values and the ki67 proliferation index. Finally, 64.29% patients were classified as SD at the end of the study, with only 14.29% of patients exhibiting PD and 21.43% patients with PR. (4) Conclusions: The quantitative analysis of 99mTcEDDA/HYNIC-TOC SPECT/CT data in patients with neuroendocrine tumours could represent an alternative to 68Ga-DOTA-peptides PET/CT for the monitoring and prognosis of NETs.

ABSTRACT

Background: Diabetes Mellitus represents a major socio-economic issue both by influencing the patient's quality of life and also considering the impact on the healthcare system. Diabetic neuropathy is one of the main complications associated, in most cases being present from the moment of diagnosis. Considering the high incidence of diabetes among patients with biliodigestive surgical conditions, a thorough analysis of the evolution and management of these patients is necessary. Materials and Methods: The association between the evolution of diabetic patients with biliodigestive conditions and diabetic neuropathy as well as risk criteria and associated complications were analyzed in a descriptive, correlational study (314 patients) conducted in the Dr. I. Cantacuzino Clinical Hospital during 2020-2022. In the study, the patients were distributed into two groups, one consisting in patients without diabetes mellitus (control group) and the second further subdivided into two groups of study, first (2a) containing patients with type II with diabetic neuropathy and high and medium risk rate, and a second one (2b) including patients with diabetes mellitus type II with confirmed neuropathy and low risk rate. Clinical and laboratory evaluations were performed and management protocols applied. Results: Statistically significant correlations were highlighted between diabetic neuropathy and the variables tested which were subsequently combined to achieve a risk score and a management protocol. Conclusions: Diabetes mellitus associated with diabetic neuropathy represents a negative prognostic factor for the postoperative outcome being associated with high risk of morbidity and mortality. The risk score and the management protocol described as results of this study represent feasible solutions and a subservient instrument in preventing the occurrence of complications in patients with bilio-digestive surgical pathologies in order to improve the prognosis and survival of the patients.

ABSTRACT

Introduction: Augmented reality (AR) devices enable doctors to associate visualizing diagnostic data, to establish therapeutic procedures in order to improve work efficiency and safety and to develop the surgical training of young doctors. This new approach may contribute to an increase in the quality of medical training and a decrease in the costs of surgeries. This paper assesses whether augmented reality can improve the results of surgical procedures as well as its possible progress in the future. Methods and results: The intra-operative use of augmented reality by using Google Glass glasses, on which we projected MRI/CT images of the anatomical areas invaded by tumors and/or images of normal anatomy, helps us to perform surgeries, as well as to present them as teaching material. We have also performed a review of the available literature, beginning with 2011 and ending with November 2021, by looking up the terms "augmented reality" and "surgical oncology" in PubMed. The results of the search were 308 studies in this field which prove the utility of the method. Many papers show that the performance of the augmented reality systems is superior and compatible with traditional imaging techniques. Conclusions: The specialty literature reveals a growing interest on the part of surgeons regarding the use of augmented reality during surgery. This procedure enables the improvement of the safety and efficiency of surgical techniques, as well as their presentation to students and residents alike. The method is innovative and has to be carefully approached before being introduced into routine practice.

ABSTRACT

Based on an experience of more than 50 years in the treatment of portal hypertension (PHT), the authors review and analyze the evolution of the surgical portocaval shunt (PCS). We would like to provide an insight into the past of PCS, in order to compare it with the current state of the treatment of PHT complications. As a landmark of the past, we shall present statistics of more than 500 cases of PHT operated between 1968 and 1983. From this group, 238 patients underwent surgical portocaval shunting during a fifteen-year period. The behavior of the portal hemodynamics following PCS was studied and the postoperative decrease in portal pressure (PP), as well as the residual PP, were recorded. The portal manometric determinations were made by electronic recordings using the Hellige device and direct intraoperative recordings through the catheterization of a ramus in the portal area. The results of PCS are superposable, in terms of hemodynamic efficiency, with those of the intrahepatic shunt (TIPS-transjugular intrahepatic portosystemic shunt). The authors discuss the current place of PCS, in obvious decline in comparison with the situation 50 years ago. The current methods of controlling variceal bleeding represent obvious progress. PCS remains with very limited indications, in specific situations when the other therapeutic methods have failed or are not recommended.

ABSTRACT

According to European consensus-based interdisciplinary guidelines for melanoma, cutaneous melanoma (CM) is the most deadly form of dermatological malignancy, accounting for 90% of the deaths of skin cancer patients. In addition to cutaneous melanoma, mucosal melanoma occurs in four major anatomical sites, including the upper respiratory tract, the conjunctiva, the anorectal region, and the urogenital area. As this cancer type metastasizes, a classification used in the current medical literature is the distinction between secondary lesions and primary malignant melanoma of the abdominal cavity. Given that malignant melanoma is the most common cancer that spreads to the gastrointestinal tract, different imaging modalities compete to diagnose the phenomenon correctly and to measure its extension. Treatment is primarily surgery-based, supported by immunotherapy, and prolongs survival, even when performed at stage IV illness. In the end, special forms of malignant melanoma are discussed, such as melanoma of the genito-urinary tract and amelanotic/achromic melanoma. The importance of this present literature review relies on yielding and grouping consistent and relevant, updated information on the many aspects and challenges that a clinician might encounter during the diagnosis and treatment of a patient with intra-abdominal melanoma.

ABSTRACT

Male breast cancers are uncommon, as men account for less than 1 percent of all breast carcinomas. Among the predisposing risk factors for male breast cancer, the following appear to be significant: (a) breast/chest radiation exposure, (b) estrogen use, diseases associated with hyper-estrogenism, such as cirrhosis or Klinefelter syndrome, and (c) family health history. Furthermore, there are clear familial tendencies, with a higher incidence among men who have a large number of female relatives with breast cancer and (d) major inheritance susceptibility. Moreover, in families with BRCA mutations, there is an increased risk of male breast cancer, although the risk appears to be greater with inherited BRCA2 mutations than with inherited BRCA1 mutations. Due to diagnostic delays, male breast cancer is more likely to present at an advanced stage. A core biopsy or a fine needle aspiration must be performed to confirm suspicious findings. Infiltrating ductal cancer is the most prevalent form of male breast cancer, while invasive lobular carcinoma is extremely uncommon. Male breast cancer is almost always positive for hormone receptors. A worse prognosis is associated with a more advanced stage at diagnosis for men with breast cancer. Randomized controlled trials which recruit both female and male patients should be developed in order to gain more consistent data on the optimal clinical approach.
