Breast cancer and its impact in male transsexuals.

INTRODUCTION: Lesbian, gay, and bisexuals have unique healthcare needs. Breast cancer is leading cancer in women, worldwide, accounting for 25% of all cases. Annual incidence rates increased significantly in all countries and age groups. The occurrence of breast cancer is rare in transgender population. As they have very limited access to medical care, it is much less likely to pursue breast cancer screening than in other individuals not identified as transgender. REVIEW OF THE CASES FROM LITERATURE: Up to date, only 13 cases of the breast cancer transsexuals (female to male) have been reported in six published papers worldwide. Histological examination of the breast tumor in female-to-male transgender showed progesterone/estrogen-positive invasive ductal carcinoma. DISCUSSION: Gender identity describes a person's inherent sense of being a woman, man, or of neither gender, whereas sexual orientation refers to how people identify their physical and emotional attraction to others. Gender reassignment surgery, as series of complex surgical genital and non-genital procedures, is recognized as the most effective treatment for patients with gender dysphoria. The two main principles of hormone therapy for transgender patients are to reduce endogenous hormone levels and their associated sex characteristics and replace them with hormones of the preferred sex. Breast cancer infrequently occurs in transgender patients. Even breast core biopsies can be difficult for interpreting after changes in breast tissue in female-to-male transsexuals following gender reassignment. CONCLUSION: Reviewing the literature, so many different data concerning probability of breast cancer in sexual minority can be found. Breast cancer screening program should be offered to all transgender individuals according to national guidelines. Very important is to take into consideration a transgender person's natal and surgical anatomy, unique clinical concerns for depression and anxiety, risk of suicide together with risk factors including experiences of harassment or physical or sexual violence, low education level, and unemployment. Understanding the need for mammography in these often marginalized groups is very important in addressing breast cancer disparities despite differences in insurance coverage in some countries and greater concern for the cancer of the breast in residual breast tissue. The best screening rule, ever, for breast cancer in male transsexuals and other similar population should be, besides surgical history and hormonal status, "Screen Now, Screen Regularly and Screen What You Have."

Intraoperative ultrasound in breast cancer surgery-from localization of non-palpable tumors to objectively measurable excision.

BACKGROUND: The utilization of intraoperative ultrasound (IOUS) in breast cancer surgery is a relatively new concept in surgical oncology. Over the last few decades, the field of breast cancer surgery has been striving for a more rational approach, directing its efforts towards removing the tumor entirely yet sparing tissue and structures not infiltrated by tumor cells. Further progress in objectivity and optimization of breast cancer excision is possible if we make the tumor and surrounding tissue visible and measurable in real time, during the course of the operation; IOUS seems to be the optimal solution to this complex requirement. IOUS was introduced into clinical practice as a device for visualization of non-palpable tumors, and compared to wire-guided localization (WGL), IOUS was always at least a viable, or much better alternative, in terms of both precision in identification and resection and for patients' and surgeons' comfort. In recent years, intraoperative ultrasound has been used in the surgery of palpable tumors to optimize resection procedures and overcome the disadvantages of classic palpation guided surgery. OBJECTIVE: The aim of this review is to show the role of IOUS in contemporary breast cancer surgery and its changes over time. METHODS: A PubMed database comprehensive search was conducted to identify all relevant articles according to assigned key words. CONCLUSION: Over time, the use of IOUS has been transformed from being the means of localizing non-palpable lesions to an instrument yielding a reduced number of positive resection margins, with a smaller volume of healthy breast tissue excided around tumor, by making the excision of the tumor optimal and objectively measurable.

Optimization of breast cancer excision by intraoperative ultrasound and marking needle - technique description and feasibility.

BACKGROUND: We present a surgical technique and the preliminary results of breast cancer excision after insertion of a specially constructed marking needle into the tumor, controlled by intraoperative ultrasound. Resection margins were projected in six directions by ultrasound measurements, determined in relation to the needle, and resection was done in accordance with those measurements. The main objective was to obtain resection margins similar (equal) to those projected by intraoperative ultrasound (10 mm). METHODS: Detailed description of the technique is given. Thirty-two female patients undergoing breast-conserving surgery, up to 30 mm in diameter, for palpable and non-palpable invasive breast cancer, were operated on using this technique. Its feasibility was tested by analyzing the success (rate) of needle placement in the tumor, the measurements executed, and the performance of the excision. RESULTS: All stages of the technique were successfully performed to completion on all 32 patients. The procedure of needle placement and ultrasound measurement of distances took 11 min on average (between 6 and 20 min). The average distance of the tumor margin from the resection margin was 12.9 mm (2 to 30 mm, 95% confidence interval [11.9, 14.06]). There was one patient with a positive resection margin (3%). CONCLUSIONS: The technique of excising palpable and non-palpable breast cancer by intraoperative ultrasound and an especially constructed marking needle is feasible and comfortable to perform. Preliminary results imply that resection volume can be rationalized, with the same or better oncological safety.

Lymph nodes behind the axillary neurovascular bundle: case report and cadaveric study of frequency and distribution.

Axillary clearance was undertaken in a 58-year-old male with massive lymph node enlargement caused by melanoma from an unknown primary site. We discovered a group of metastatic lymph nodes behind the axillary neurovascular bundle. This group of nodes (retro-axillary lymph nodes) could represent an extension of the subscapular group, or the seventh group of axillary lymphoid nodes. They were successfully removed using an ad hoc surgical technique, and the subsequent findings are presented herein. To check the frequency of these lymph nodes in this area, we conducted a study on 15 cadavers (30 armpits). The technique of cadaveric sampling is described. Retro-axillary tissue was histologically processed to determine the number of lymph nodes present. It was found that lymph nodes were present in the defined area in 18 of the 30 (60 %) armpits explored. We recommend assessment of the retro-axillary space during surgery entailing massive axillary lymph node involvement.

Early left ventricular systolic and diastolic dysfunction in patients with newly diagnosed obstructive sleep apnoea and normal left ventricular ejection fraction.

UNLABELLED: The aim of the study was to evaluate whether obstructive sleep apnea (OSA) contributes directly to left ventricular (LV) diastolic and regional systolic dysfunction in newly diagnosed OSA with normal left ventricle ejection fraction. METHODS: 125 consecutive patients were prospectively enrolled in the study. Control group consisted of 78 asymptomatic age-matched healthy subjects who did not have any cardiovascular and respiratory diseases. All patients had undergone overnight polysomnography and standard transthoracic and tissue Doppler imaging echocardiogram. RESULTS: The E/A ratio and the peak E wave at mitral flow were significantly lower and the peak A wave at mitral flow was significantly higher in OSA patients compared with control subjects. Left ventricle isovolumetric relaxation time (IVRT) and mitral valve flow propagation (MVFP) were significantly longer in OSA patients than in controls. Tissue Doppler derived S' amplitude of lateral part at mitral valve (S'Lm) and E' wave amplitudes both at the lateral (E'Lm) and septal parts of the mitral valve (E'Sm) were significantly lower in OSA patients compared to controls. CONCLUSION: Newly diagnosed OSA patients with normal global LV function have significantly impaired diastolic function and regional longitudinal systolic function. OSA is independently associated with these changes in LV function.

Totally implantable central venous catheters of the port-a-cath type: complications due to its use in the treatment of cancer patients.

PURPOSE: A multidisciplinary approach to the treatment of patients with malignant diseases requires adequate venous access in order to safely administer chemotherapy, blood transfusion and blood products, antibiotics, rehydratation and total parenteral nutrition. The insertion of the central venous catheter (CVC), its use and its maintenance can be accompanied by multiple complications. METHODS: Fifty cancer patients were retrospectively enrolled in this study. The obligatory inclusion criterion was an implanted CVC of the port-a-cath type, inserted for chemotherapy administration. This study included patients who had their catheters inserted in the period from 2001 to 2012. RESULTS: The median patient age was 44 years (range 28- 68). Thirty five patients (70%) were female and 15 (30%) male. The port-a-cath had been used from 1 to 40 months (16.8 ± 9 months on average). Breast cancer was the most frequent malignancy (18 patients, 36%). The overall incidence of reported complications was 38%. The most common complications were infections and thromboembolic events, each with an incidence of 10 %. The malposition and disconnection of the port-a-cath were in second place, each with an incidence of 6%. CONCLUSION: Insertion of the CVC carries the possibility of serious complications (thrombosis, infections, occlusions). However, correct implantation and handling performed by experienced and trained surgical and other medical staff significantly decrease the incidence of these complications. The use of the CVC has greatly improved the quality of life and also decreased the morbidity and mortality of the cancer patients in our study.

Non-Invasive 3D Breast Tumor Localization: A Viable Alternative to Invasive Tumor Marking.

Background: We present a detailed description and the preliminary results of our original technique for non-invasive three-dimensional tumor localization in the breast, which was created as an alternative to standard invasive tumor marking before neoadjuvant systemic therapy (NAST), aiming to enable adequate surgery after complete tumor regression. Methods: A detailed description of the technique is provided in the main text. The technique's feasibility and precision were assessed in a single-arm, prospective study based on the histological parameters of the adequacy and rationality of the excision of completely regressed tumor beds. Results: Out of 94 recruited patients, 15 (16%) were deemed unsuitable, mainly due to the tumors' inadequate ultrasound visibility. Among the 79 processed patients, 31 (39%) had complete clinical regression after NAST and were operated on using our technique. The histological parameters of surgical precision (signs of tumor regression: 24/31; microscopic cancer residues: 7/31) were verified in all excised specimens (100% precision). There were no positive margins in seven cases with microscopic residues, indicating our technique's capacity to enable oncologically safe post-NAST surgery. Conclusions: The proposed technique is feasible and satisfactorily accurate in determining the location of regressed tumors, thus representing an alternative to invasive tumor marking, especially in surgical centers lacking trained staff and equipment for invasive marking. The technique's limitations are mainly related to the inadequate ultrasound visibility of the tumor.

Obstructive jaundice treatment during the COVID-19 pandemic: retrospective cohort study at a single tertiary care center in Serbia.

OBJECTIVE: We aimed to compare mortality and complication rates in patients treated for obstructive jaundice before and during the COVID-19 pandemic in a tertiary care center in Serbia. METHODS: We conducted a retrospective cohort study among a first group of patients treated between 1 January 2017 and 1 January 2019. The second group was treated between 1 March 2020 and 1 March 2022. RESULTS: The first group comprised 35 patients, and the second group (in which all patients were SARS-CoV-2 positive) included 18 patients; 37 and 16 patients were treated for malignant and benign diseases, respectively. The groups did not differ significantly regarding the diagnoses and treatment received. The second group showed significantly higher aspartate aminotransferase levels and lower white blood cell, C-reactive protein, and interleukin 6 levels. Mortality and complication rates did not differ significantly between groups. All deceased patients in the second group had significant radiologic findings associated with COVID-19 pneumonia. CONCLUSIONS: COVID-19 infection is a risk factor in treating obstructive jaundice. This study illustrates the potential influence of COVID-19 on mortality after obstructive jaundice treatment. COVID-19 pneumonia may be a significant risk factor for mortality in patients treated for obstructive jaundice.

Changing the role of pCR in breast cancer treatment - an unjustifiable interpretation of a good prognostic factor as a "factor for a good prognosis".

Pathologic complete response (pCR) after neoadjuvant systemic therapy (NAST) of early breast cancer (EBC) has been recognized as a good prognostic factor in the treatment of breast cancer because of its significant correlation with long-term disease outcome. Based on this correlation, pCR has been accepted by health authorities (FDA, EMA) as a surrogate endpoint in clinical trials for accelerated drug approval. Moreover, in recent years, we have observed a tendency to treat pCR in routine clinical practice as a primary therapeutic target rather than just one of the pieces of information obtained from clinical trials. These trends in routine clinical practice are the result of recommendations in treatment guidelines, such as the ESMO recommendation "…to deliver all planned (neoadjuvant) treatment without unnecessary breaks, i.e. without dividing it into preoperative and postoperative periods, irrespective of the magnitude of tumor response", because "…this will increase the probability of achieving pCR, which is a proven factor for a good prognosis…". We hypothesize that the above recommendations and trends in routine clinical practice are the consequences of misunderstanding regarding the concept of pCR, which has led to a shift in its importance from a prognostic factor to a desired treatment outcome. The origin of this misunderstanding could be a strong subconscious incentive to achieve pCR, as patients who achieved pCR after NAST had a better long-term outcome compared with those who did not. In this paper, we attempt to prove our hypothesis. We performed a comprehensive analysis of the therapeutic effects of NAST and adjuvant systemic therapy (AST) in EBC to determine whether pCR, as a phenomenon that can only be achieved at NAST, improves prognosis per se. We used published papers as a source of data, which had a decisive influence on the formation of the modern attitude towards EBC therapy. We were unable to find any evidence supporting the use of pCR as a desired therapeutic goal because NAST (reinforced by pCR) was never demonstrated to be superior to AST in any context.

Early dumping syndrome and reflux esophagitis prevention with pouch reconstruction.

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

Importance of revealing a rare case of breast cancer in a female to male transsexual after bilateral mastectomy.

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

D-dimer, CRP, PCT, and IL-6 Levels at Admission to ICU Can Predict In-Hospital Mortality in Patients with COVID-19 Pneumonia.

INTRODUCTION: Health care workers have had a challenging task since the COVID-19 outbreak. Prompt and effective predictors of clinical outcomes are crucial to recognize potentially critically ill patients and improve the management of COVID-19 patients. The aim of this study was to identify potential predictors of clinical outcomes in critically ill COVID-19 patients. METHODS: The study was designed as a retrospective cohort study, which included 318 patients treated from June 2020 to January 2021 in the Intensive Care Unit (ICU) of the Clinical Hospital Center "Bezanijska Kosa" in Belgrade, Serbia. The verified diagnosis of COVID-19 disease, patients over 18 years of age, and the hospitalization in ICU were the criteria for inclusion in the study. The optimal cutoff value of D-dimer, CRP, IL-6, and PCT for predicting hospital mortality was determined using the ROC curve, while the Kaplan-Meier method and log-rank test were used to assess survival. RESULTS: The study included 318 patients: 219 (68.9%) were male and 99 (31.1%) female. The median age of patients was 69 (60-77) years. During the treatment, 195 (61.3%) patients died, thereof 130 male (66.7%) and 65 female (33.3%). 123 (38.7%) patients were discharged from hospital treatment. The cutoff value of IL-6 for in-hospital death prediction was 74.98 pg/mL (Sn 69.7%, Sp 62.7%); cutoff value of CRP was 81 mg/L (Sn 60.7%, Sp 60%); cutoff value of procalcitonin was 0.56 ng/mL (Sn 81.1%, Sp 76%); and cutoff value of D-dimer was 760 ng/mL FEU (Sn 63.4%, Sp 57.1%). IL-6 ≥ 74.98 pg/mL, CRP ≥ 81 mg/L, PCT ≥ 0.56 ng/mL, and D-dimer ≥ 760 ng/mL were statistically significant predictors of in-hospital mortality. CONCLUSION: IL-6 ≥ 74.98 pg/mL, CRP values ≥ 81 mg/L, procalcitonin ≥ 0.56 ng/mL, and D-dimer ≥ 760 ng/mL could effectively predict in-hospital mortality in COVID-19 patients.

Obstructive jaundice and cholangitis caused by an arterial ring of the proper hepatic artery around the common bile duct.

BACKGROUND: Many different benign and malignant diseases can cause obstruction of the extrahepatic biliary duct. One of the more serious complications of biliary obstruction is cholangitis leading to emergency decompression. Anatomic variations are frequent in this region; however, it has rarely been reported that the extrahepatic bile duct is compressed by the arterial vessels. CASE REPORT: We present the case of a 68-year-old woman who was admitted through the emergency department of our hospital with jaundice, abdominal pain and fever. Biochemical analyses of liver function showed increased value of AST (113 IU/L) and AST (128 IU/L). Total bilirubin was 5.88 mg/dl, conjugated bilirubin was 3.00 mg/dl, and alkaline phosphatase was 393 IU/L. We performed abdominal ultrasound (US), magnetic resonance cholangiopancreatography (MRCP), and computed tomography (CT) imaging. Multislice CT angiography showed that the arterial ring of the common hepatic artery around the common bile duct (CBD) originated from the superior mesenteric artery. Cholecystectomy and intraoperative cholangiography were performed, as well as decompression and lavage of the biliary tree. Escherichia coli was identified from bile. Dissection of the hepatoduodenal ligament confirmed that the proper hepatic artery made a vascular ring around the CBD. Finally, a T tube was placed into the CBD. During 5 years of follow-up the patient has been without recurrent episodes of jaundice. In such cases dissection of the proper hepatic artery from the common hepatic duct is the treatment of choice. CONCLUSIONS: If there are signs of cholangitis decompression and lavage of the biliary tree with "T", drainage should be performed. Vascular malformations should be considered as a possible cause of extrahepatic biliary obstruction. CT angiography may be helpful in identifying these malformations.

Predictors of Mortality in Critically Ill COVID-19 Patients Demanding High Oxygen Flow: A Thin Line between Inflammation, Cytokine Storm, and Coagulopathy.

INTRODUCTION: Mortality among critically ill COVID-19 patients remains relatively high despite different potential therapeutic modalities being introduced recently. The treatment of critically ill patients is a challenging task, without identified credible predictors of mortality. METHODS: We performed an analysis of 160 consecutive patients with confirmed COVID-19 infection admitted to the Respiratory Intensive Care Unit between June 23, 2020, and October 2, 2020, in University Hospital Center Bezanijska kosa, Belgrade, Serbia. Patients on invasive, noninvasive ventilation and high flow oxygen therapy with moderate to severe ARDS, according to the Berlin definition of ARDS, were selected for the study. Demographic data, past medical history, laboratory values, and CT severity score were analyzed to identify predictors of mortality. Univariate and multivariate logistic regression models were used to assess potential predictors of mortality in critically ill COVID-19 patients. RESULTS: The mean patient age was 65.6 years (range, 29-92 years), predominantly men, 68.8%. 107 (66.9%) patients were on invasive mechanical ventilation, 31 (19.3%) on noninvasive, and 22 (13.8%) on high flow oxygen therapy machine. The median total number of ICU days was 10 (25th to 75th percentile: 6-18), while the median total number of hospital stay was 18 (25th to 75th percentile: 12-28). The mortality rate was 60% (96/160). Univariate logistic regression analysis confirmed the significance of age, CRP, and lymphocytes at admission to hospital, serum albumin, D-dimer, and IL-6 at admission to ICU, and CT score. Serum albumin, D-dimer, and IL-6 at admission to ICU were independently associated with mortality in the final multivariate analysis. CONCLUSION: In the present study of 160 consecutive critically ill COVID-19 patients with moderate to severe ARDS, IL-6, serum albumin, and D-dimer at admission to ICU, accompanied by chest CT severity score, were marked as independent predictors of mortality.
