RESUMO

Endometriosis (E) and adenomyosis (A) are associated with a wide spectrum of symptoms and may present various histopathological transformations, such as the presence of hyperplasia, atypia, and malignant transformation occurring under the influence of local inflammatory, vascular and hormonal factors and by the alteration of tumor suppressor proteins and the inhibition of cell apoptosis, with an increased degree of lesion proliferation. MATERIAL AND METHODS: This retrospective study included 243 patients from whom tissue with E/A or normal control uterine tissue was harvested and stained by histochemical and classical immunohistochemical staining. We assessed the symptomatology of the patients, the structure of the ectopic epithelium and the presence of neovascularization, hormone receptors, inflammatory cells and oncoproteins involved in lesion development. Atypical areas were analyzed using multiple immunolabeling techniques. RESULTS: The cytokeratin (CK) CK7+/CK20- expression profile was present in E foci and differentiated them from digestive metastases. The neovascularization marker cluster of differentiation (CD) 34+ was increased, especially in areas with malignant transformation of E or A foci. T:CD3+ lymphocytes, B:CD20+ lymphocytes, CD68+ macrophages and tryptase+ mast cells were abundant, especially in cases associated with malignant transformation, being markers of the proinflammatory microenvironment. In addition, we found a significantly increased cell division index (Ki67+), with transformation and inactivation of tumor suppressor genes p53, B-cell lymphoma 2 (BCL-2) and Phosphatase and tensin homolog (PTEN) in areas with E/A-transformed malignancy. CONCLUSIONS: Proinflammatory/vascular/hormonal changes trigger E/A progression and the onset of cellular atypia and malignant transformation, exacerbating symptoms, especially local pain and vaginal bleeding. These triggers may represent future therapeutic targets.

RESUMO

Background and Objective: In the therapeutic strategy of rectal cancer, radiotherapy has consolidated its important position and frequent use in current practice due to its indications as neoadjuvant, adjuvant, definitive, or palliative treatment. In recent years, total neoadjuvant therapy (TNT) has been established as the preferred regimen compared to concurrent neoadjuvant chemoradiotherapy (CRT). In relation to better outcomes, the percentage of patients who achieved pathological complete response (pCR) after neoadjuvant treatment is higher in the case of TNT. This study aimed to analyze the response to TNT compared to neoadjuvant CRT regarding pCR rate and the change in staging after surgical intervention. Materials and Methods: We performed a retrospective study on 323 patients with rectal cancer and finally analyzed the data of 201 patients with neoadjuvant treatment, selected based on the inclusion and exclusion criteria. Patients received CRT neoadjuvant therapy or TNT neoadjuvant therapy with FOLFOX or CAPEOX. Results: Out of 157 patients who underwent TNT treatment, 19.74% had pathological complete response, whereas in the group with CRT (n = 44), those with pCR were 13.64%. After neoadjuvant treatment, the most frequent TNM classifications were ypT2 (40.30%) and ypN0 (79.10%). The statistical analysis of the postoperative disease stage, after neoadjuvant therapy, showed that the most frequent changes were downstaging (71.14%) and complete response (18.41%). Only four patients (1.99%) had an upstaging change. The majority of patients (88.56%) initially presented clinical evidence of nodal involvement whereas only 20.9% of the patients still presented regional disease at the time of surgical intervention. Conclusions: By using TNT, a higher rate of stage reduction is obtained compared to the neoadjuvant CRT treatment. The post-neoadjuvant-treatment imagistic evaluation fails to accurately evaluate the response. A better response to TNT was observed in young patients.

RESUMO

Breast cancer is often seen as a disease that occurs in women, but it can also appear in men in a very small percentage, below 1%. Men have a minimal amount of breast tissue compared to women, which has the potential to become malignant in a similar way to women, although much less frequently. A patient presented with advanced local invasion due to the low amount of breast tissue, with the tumor quickly invading the adjacent structures. Histopathological and immunohistochemical examinations have an extremely important role in the pathology of breast cancer. Given that male breast cancer is rare and there are not enough surgeons specializing in breast surgery in our country, there is a lack of experience in the management and early diagnosis of this type of cancer, which will be highlighted in this article.

RESUMO

In this paper, we present, in detail, the simplified perfusion technique that we have adopted since January 2009 and that we have utilized in 200 cases for cardiac minimally invasive valvular procedures that were performed through a right lateral mini-thoracotomy in the 3(rd)-4(th) intercostal space. Cardiopulmonary bypass was achieved by means of the direct cannulation of the ascending aorta and the insertion of a percutaneous venous cannula in the femoral vein. A flexible aortic cross-clamp was applied through the skin incision and cardioplegic arrest was obtained with the antegrade delivery of a crystalloid solution. Gravity drainage was enhanced by vacuum-assisted aspiration. There were no technical complications related to this perfusion technique that we have adopted in minimally invasive surgical procedures.

RESUMO

This study aims to assess the impact of SARS-CoV-2 on a population enrolled in a pilot colorectal screening program started by a family doctor in Romania. This observational retrospective study was spread over 43 months, respectively, from October 2019 to April 2023, and included 169 patients. The primary objective was to compare the pre-pandemic, pandemic, and post-pandemic periods to observe significant changes. The secondary objective was to study the correlation between vaccination against SARS-CoV-2 and participation in the study, especially in the age range class of interest-50-74 years. These data are important because Romanian Healthcare policymakers can use them to estimate the participation rate in a future national colorectal cancer screening and how to adjust and facilitate their communications with the targeted population. The rise of COVID-19 significantly negatively impacted the number of patients adhering to the pilot colorectal cancer screening and the number of test results during the pandemic period. However, in the post-pandemic period, the number of patients who joined the study, and the number of fecal occult blood tests was greater than expected (128.74%). We observed that screening participation was associated with vaccination (78.11% of patients had a complete COVID-19 vaccine scheme).

RESUMO

This study aims to develop a scoring method that can be used by primary care physicians from remote areas or resource-limited settings to estimate the need for fecal occult blood testing (FOBT) as a first step in colorectal cancer screening. This method relies on several modifiable risk factors that can influence a positive FOBT, an indication of the presence of colorectal polyps, or even colorectal cancer. The scoring method considers, besides the age and gender of the patient, the body mass index (BMI), smoking status, and the diagnoses of diabetes mellitus (type 2 diabetes), dyslipidemia, and hypertension. It does not need any paraclinical exams, which is an advantage when access or material resources are limited. The retrospective study was spread over forty-three months, respectively, from October 2019 to April 2023, and included 112 patients. The score that we designed is a numerical value between 0 and 7. The values between 0 and 3 represent a smaller risk of a positive FOBT (9.68%), values 4 and 5 represent a medium risk (14.75%), while values 6 and 7 represent a greater risk (40%). Using this score, a physician can determine if a patient has a greater risk and recommend it to prioritize taking a FOB test.

RESUMO

The objective of this study is to investigate the feasibility of colorectal cancer (CRC) screening in the absence of a national screening program using the resources provided by the Romanian healthcare system. Study participants were recruited from adult patients (over 18 years old) registered with a general practitioner from an urban area over a period of 3 years (October 2019 to September 2022). Patients were recruited when they came for a consult at their family physician's office. The study excluded patients with a medical history of colorectal cancer. Written consent was obtained from the patients who agreed to participate. Patients who agreed to participate were recommended to undergo a fecal occult blood test (FOBT). For those with a positive FOBT result, a colonoscopy was recommended. The study identified a need and willingness of patients to participate in CRC screening when they were informed about it, especially when it involved a noninvasive test such as FOB. We did not anticipate the refusal to perform FOBT in the public healthcare system because the recommendation was made by a GP. We identified a deficit of specialists that can perform colonoscopies in the public healthcare system, insufficient health education, and a lack of dedicated pathways for screening.

RESUMO

Oropharyngeal squamous cell carcinoma (OPSCC) development is strongly associated with risk factors like smoking, chronic alcohol consumption, and the living environment, but also chronic human papilloma virus (HPV) infection, which can trigger cascade cellular changes leading to a neoplastic transformation. The prevalence of these factors differs among different world regions, and the prevention, diagnosis, and prognosis of OPSCC are highly dependent on them. We performed a retrospective study on 406 patients diagnosed with OPSCC in our region that were classified according to the tumor type, localization and diagnosis stage, demographic characteristics, risk factors, and histological and immunohistochemical features. We found that most of the patients were men from urban areas with a smoking habit, while most of the women in our study were diagnosed with tonsillar OPSCC and had a history of chronic alcoholism. During the immunohistochemical study, we analyzed the tumor immunoreactivity against anti-p16 and anti-HPV antibodies as markers of HPV involvement in tumor progression, as well as the correlation with the percentage of intratumoral nuclei immunomarked with the anti-Ki 67 antibody in serial samples. We observed that the percentage of Ki67-positive nuclei increased proportionally with the presence of intratumoral HPV; thus, active HPV infection leads to an increase in the rate of tumor progression. Our results support the implementation of strategies for OPSCC prevention and early diagnosis and can be a starting point for future studies aiming at adapting surgical and oncological treatment according to the HPV stage for better therapeutic results.

RESUMO

AIM: The aim of this investigation is to reduce blood transfusion in cardiac surgery patients with preoperative conditions predictive for transfusion requirements. We compared the amount of blood transfused in two groups of patients undergoing cardiopulmonary bypass (CPB) with two different circuit systems. METHODS: Sixty patients undergoing cardiac surgery were randomly assigned to two groups: in group A (N=30) cardiopulmonary bypass was accomplished with an open circuit and in group B (N=30) with a closed circuit. The open circuit consisted of a cardiotomy reservoir, a membrane oxygenator and an arterial line filter, while the closed circuit was made up of a collapsible venous reservoir, a membrane oxygenator, an arterial line filter and a cardiotomy reservoir. The amount of transfused packed red cells in each patient was measured until discharge from the hospital. RESULTS: Groups were similar regarding age, gender, body surface area (BSA), New York Heart Association (NYHA) class and comorbidity risk factors. Moreover, there were no significant differences between groups regarding the type of procedures, CPB and aortic cross-clamp times, total amount of cardioplegia and urinary output during CPB. Priming volume was 1180+/-84 mL (group A) and 760+/-72 mL (group B) (P<0.001). Significant differences in transfusion requirements emerged in the two groups: the total volume of packed red cells transfused for each patient was significantly higher in the open system group compared to the closed system group (717+/-486 mL versus 378+/-364 mL) (P=0.003). Clinical outcomes were similar in both groups. CONCLUSION: In patients with preoperative conditions predictive for the need of transfusions, the use of a closed cardiopulmonary bypass circuit can diminish the amount of transfused blood products.

RESUMO

Integral arterial myocardial revascularization seems to become the standard method in coronary surgery, but the international experience is still limited. We are communicating our results in arterial off pump coronary artery grafting (OFF CABG) in a centre specialized in "on pump" total arterial revascularisation. Between January 2004 and June 2006 we performed off pump CABG in 58 patients, using skeletonized arterial grafts; the vein grafts was rarely used. In 94.95% of cases we used only arterial grafts, and we achieved complete arterial revascularization in 47 (81.03%) of cases. We didn't noted major postoperative complications, the mean UCU stay was 1.7 days, mean hospital stay was 7.3 days, and no postoperative deaths were noted. The off pump CABG using arterial grafts is a secure method, without postoperative complications, which offers viable solutions of complete revascularization of the heart.

RESUMO

Surgery in patients with multiple sclerosis, the most common autoimmune demyelinating disorder of the central nervous system, represents a challenge for surgeons and anesthesiologists because of the reported risk of relapse of the neurologic symptoms in the perioperative period. In this report, we describe the management of a patient with relapsing-remitting multiple sclerosis and critical coronary artery disease, who underwent an uneventful off-pump coronary artery revascularization. The issues pertaining to the performance of coronary surgery revascularization on patients with multiple sclerosis are discussed.
