RESUMO

Background: Transcatheter aortic valve replacement (TAVR) has become the dominant treatment for aortic valve disease. While TAVR safety has improved over time, concern remains over the occurrence of cerebrovascular accidents (CVA) secondary to device placement, which is associated with increased morbidity and mortality. The Sentinel Cerebral Protection System (CPS) was developed to reduce the risk of embolic strokes associated with debris produced during TAVR. Studies evaluating Sentinel CPS efficacy have produced conflicting results, and there is little understanding of which patients are selected for device placement in "real-world" settings. With no existing guidelines on device use, the purpose of this study was to describe and compare the characteristics of patients who receive CPS with those who do not in a "real-world" setting of consecutive TAVR patients and evaluate its impact on postoperative complications, namely stroke. Methods: This was a single-center, retrospective study of all patients undergoing TAVR between July 1, 2019, and December 31, 2020. Patient demographics, baseline, and perioperative characteristics were collected prospectively using the Society of Thoracic Surgeons (STS)/American College of Cardiology (ACC) Transcatheter Valve Therapy (TVT) Registry and our institution's TAVR database for analysis. Postoperative outcomes were assessed using primary endpoints of in-hospital/30-day stroke and the composite of death, stroke, and bleeding/vascular events at one-year. To adjust for baseline differences, a propensity score was developed including all factors that were different between groups, and Multivariate Cox Regression analysis was used to control for these differences. Patient follow-up was 97% complete at 12 months with 100% echocardiographic follow-up. Results: A total of 242 consecutive patients (57.9% male) were analyzed, with a mean age of 79.9 ± 9 years. Of these patients, 134 (55.4%) received the Sentinel CPS and 108 (44.6%) did not. Sentinel CPS patients were more likely to be male, not on dialysis, without prior CVA or pacemaker, had less severe chronic lung disease, and were lower operative risk compared to concurrent non-CPS patients. CPS patients were also found to have higher hemoglobin and albumin levels, lower creatinine, and were less likely to be on immunosuppressant therapy. The incidence of in-hospital/30-day stroke after TAVR did not differ between CPS and non-CPS patients (0.0% vs. 1.9%; p = 0.198). Unadjusted analyses at one-year showed a lower occurrence of the composite endpoint in CPS patients compared non-CPS patients (8.3% vs. 17.0%; p = 0.034). After adjustment, the hazard ratio (Adj HR) for the CPS group was no longer significantly associated with a lower composite endpoint (Adj HR = 0.609, 95% CI 0.244-1.523; p = 0.289). Both unadjusted (p = 0.233) and adjusted (p = 0.132) analyses showed no difference in the incidence of stroke at one-year. Conclusions: Our study demonstrates that in a "real-world" setting, the Sentinel CPS device is more likely to be used in healthier and less complex patients. In analyses adjusted for illness severity and patient complexity, CPS use did not have a significant effect on the incidence of in-hospital/30-day stroke or the composite endpoint of death, stroke, and bleeding/vascular events at one-year.

RESUMO

Bicuspid Aortic Valves (BAV) are associated with an increased incidence of thoracic aortic aneurysms (TAA). TAA are a common aortic pathology characterized by enlargement of the aortic root and/or ascending aorta, and may become life threatening when left untreated. Typically occurring as the sole pathology in a patient, TAA are largely asymptomatic. However, in some instances, they are accompanied by aortic valve (AV) diseases: either congenital BAV or acquired in the form of Aortic Insufficiency (AI) or aortic stenosis (AS). When TAA are associated with aortic valve disease, determining an accurate and predictable prognosis becomes especially challenging. Patients with AV disease and concomitant TAA lack a widely accepted diagnostic approach, one that integrates our knowledge on aortic valve pathophysiology and encompasses multi-modality imaging approaches. This review summarizes the most recent scientific knowledge regarding the association between AV diseases (BAV, AI, AS) and ascending aortopathies (dilatation, aneurysm, and dissection). We aimed to pinpoint the gaps in monitoring practices and prediction of disease progression in TAA patients with concomitant AV disease. We propose that a morphological and functional analysis of the AV with multi-modality imaging should be included in aortic surveillance programs. This strategy would allow for improved risk stratification of these patients, and possibly new AV phenotypic-specific guidelines with more vigilant surveillance and earlier prophylactic surgery to improve patient outcomes.

RESUMO

AIM: This study aimed to assess technical aspects and clinical results of a new minimally invasive technique in parastomal hernia (PSH) repair, full endoscopic retromuscular access, after 2 years of follow-up. METHODS: Data from consecutive patients requiring minimally invasive ventral PSH repair were collected from 2019 to 2022. The inclusion criteria were patients aged between 18 and 80 years old with symptomatic PSH. Demographics and perioperative and postoperative data were collected. Postoperative pain and functional recovery were compared with preoperative data. RESULTS: Twelve patients with symptomatic PSH were included. The mean PSH defect area was 16.2 cm2 and the mean midline defect was 8.7 cm2 . No intra-operative complications or conversion to open surgery were detected. One patient (8%) required postoperative readmission due to partial bowel obstruction symptoms that required catheterization of the stoma. Pain significantly worsened after the first postoperative day compared to preoperative data but improved after the first postoperative month compared to the first postoperative week and after the 90th postoperative day compared to the first postoperative month, with significant differences. Significant restriction improvement was identified when 30 days after surgery data were compared to preoperative data and when the 180th postoperative day results were compared to 30 days after surgery. The average follow-up was 29 months. During the follow-up no clinical or radiological recurrence was observed. CONCLUSION: This paper shows low rate of intra- and postoperative complications with significant improvement in terms of pain activities restriction compared to preoperatory. After 29 months follow-up, no recurrence was identified, confirming that this approach offers good mid-term results.

RESUMO

Cervical cancer represents a major public health problem, being the fourth most common cancer in incidence and mortality in women worldwide. Patients with recurrent, persistent, or metastatic disease unsuitable for curative therapeutic approaches have a dismal prognosis. Until recently, these patients were only candidates for cisplatin-based chemotherapy plus bevacizumab. However, the introduction of immune checkpoint inhibitors has revolutionized the treatment of this disease, achieving historical overall survival improvements in both the post-platinum and front-line settings. Interestingly, the clinical development of immunotherapy in cervical cancer is currently advancing to the locally advanced setting, although preliminary efficacy outcomes in this setting have been disappointing so far. Moreover, promising data are emerging from early-phase trials on novel immunotherapy approaches, such as human papillomavirus therapeutic vaccines and adoptive cell therapy. This review summarizes the main clinical trials carried out in the field of immunotherapy in the last several years.

RESUMO

PURPOSE: To identify response predictors in patients with head and neck squamous cell carcinoma (N + HNSCC) and persistent lymph nodes after curative chemoradiotherapy treatment (CCRT). MATERIALS AND METHODS: Consecutive patients with N + HNSCC treated with CCRT and persistent lymph nodes at first follow-up between 2015 and 2021 were identified and analyzed. Complete response was defined as the absence of lymph node metastatic involvement in patients with salvage lymphadenectomy or the absence of progression after 1 year of successive follow-ups. Tumour type and location, staging, and human papillomavirus (HPV) status were considered for analysis. The number and size of lymph nodes, type, shape, enhancement and margins on diagnostic and follow-up CT were also analyzed. RESULTS: The cohort included 46 patients with 134 pathological lymph nodes. Logistic regression models showed the following variables to be significant: performance of salvage lymphadenectomy (OR 0.094, [CI 95% 0.004-0.61], p = 0.037); the type of lymphadenopathy on diagnostic CE-CT (solid vs. cystic) (N1: OR = 4.11, [CI 95% 1.11-17.93], p = 0.042 and N3: OR 6.42, [CI 95% 1.2-42.56], p = 0.036); the change of shape (round to oval) on the follow-up CE-CT (OR 9.76, [CI 95% 1.79-8.57], p = 0.016) and the time in days between CCRT and the first follow-up CE-CT (OR 1.06, [CI 95% 1.004-1.13], p = 0.048). CONCLUSIONS: In our experience, the presence of solid lymph nodes on pre-treatment CT and the change in shape from round to oval on post-treatment CT are predictors of response to treatment in patients with N + HNSCC persistent lymph nodes after CCRT. Increasing the temporal interval between treatment and follow-up CT should be considered to avoid unnecessary nodal dissections.

RESUMO

The current situation of the SARS-CoV-2 pandemic has paralyzed non-urgent and/or oncological surgery in many hospitals in our country with what it means for the health of citizens who are awaiting a surgical procedure. Outpatient Surgery can afford more than 85% of the surgical procedures that are performed in a surgical department and is presented as a feasible and safe alternative at the present time since it does not require admission and decreases clearly the risk of infection. In addition, it is the tool that should be generalized to solve the accumulation of patients on the waiting list that the pandemic is generating, so it seems appropriate that the Ambulatory Surgery section of the Spanish Association of Surgeons present a series of recommendations for the implementation of outpatient surgery in these exceptional circumstances that we have to live.

RESUMO

PURPOSE OF REVIEW: We review the new systemic treatment strategies for differentiated thyroid carcinoma, as well as the acquaintance of its molecular biology. RECENT FINDINGS: Multiple kinase inhibitor drugs have become the standard therapy for thyroid cancer, albeit several adverse effects. In the last few years, new molecules have raised with an overall safety profile. Most of them, are considered targeted therapies directed toward driven-molecules alterations, such as neurotrophic tyrosine kinase receptor (NTRK) inhibitors for NTRK-fusion thyroid cancer and rearranged during transfection (RET) inhibitors for RET-fusion thyroid cancer. Recently, promising outcomes and safety data have been presented. Furthermore, other novel strategies for advanced thyroid carcinoma are currently investigated in clinical trials.The ability to provide precision medicine to patients in routine clinical settings depends on the availability of molecular profiling test at their cancer centers. The impossibility to perform molecular characterization could turn out to be a diagnostic and treatment limitation for some patients. SUMMARY: The treatment of advanced differentiated thyroid carcinoma has undergone rapid evolution in the last decade. An emerging treatment era is coming. From now to then, we will need to face the different types of diagnostic tools for molecular characterization, their interpretation and, finally the access to targeted therapies.

RESUMO

BACKGROUND: When Rectocele is part of a complex pelvic organ prolapse, a full repair is recommended. The aim of this study was to evaluate the clinical and radiological results after laparoscopic surgery in patients with symptomatic rectocele and III/IV stage vaginal vault prolapse METHODS: This is a prospective cohort study of women with symptomatic rectoceles and middle compartment prolapse operated on between 2013 and 2015, who underwent a laparoscopic sacrocolpoperineopexy with synthetic Y mesh attached to puborectalis muscles, the anterior and posterior vagina wall and the sacrum. The clinical outcomes measured were symptoms of prolapse, obstructive defecation syndrome and quality of life. Radiological outcomes were distance of the vaginal vault below pubococcigeal line and depth of rectovaginal wall protrusion in dynamic pelvic resonance. RESULTS: 33 patients were included. 32 of them remained asymptomatic after a three years follow-up. Significant differences were shown in the obstructed defecation score and quality of life after 6, 12 and 36 months compared to preoperatively. No differences were identified when the postoperative results were compared. Significant differences were shown in preoperative vaginal vault prolapse (3.2 cms ± 0.8 SD below the pubococcigeal Line) and rectocele size, compared with 1 and 3 years after surgery. There were no significant differences in vaginal vault prolapse when compared after 1 and 3 years. When rectocele size after 1 and 3 years was compared, significant differences were shown, but only one clinical recurrence (3%) was identified after a mean follow-up of 47 months. CONCLUSIONS: Laparoscopic sacrocolpoperineopexy in patients with symptomatic rectocele and III/IV vaginal vault prolapse solves the constipation and obstructed defecation with an excellent quality of life and low clinical recurrences. Radiological deterioration, especially in rectocele size, was identified in the mid-term follow-up without clinical significance.

RESUMO

Aortic valve sclerosis is a highly prevalent, poorly characterized asymptomatic manifestation of calcific aortic valve disease and may represent a therapeutic target for disease mitigation. Human aortic valve cusps and blood were obtained from 333 patients undergoing cardiac surgery (n = 236 for severe aortic stenosis, n = 35 for asymptomatic aortic valve sclerosis, n = 62 for no valvular disease), and a multiplex assay was used to evaluate protein expression across the spectrum of calcific aortic valve disease. A subset of six valvular tissue samples (n = 3 for asymptomatic aortic valve sclerosis, n = 3 for severe aortic stenosis) was used to create RNA sequencing profiles, which were subsequently organized into clinically relevant gene modules. RNA sequencing identified 182 protein-encoding, differentially expressed genes in aortic valve sclerosis vs. aortic stenosis; 85% and 89% of expressed genes overlapped in aortic stenosis and aortic valve sclerosis, respectively, which decreased to 55% and 84% when we targeted highly expressed genes. Bioinformatic analyses identified six differentially expressed genes encoding key extracellular matrix regulators: TBHS2, SPARC, COL1A2, COL1A1, SPP1, and CTGF. Differential expression of key circulating biomarkers of extracellular matrix reorganization was observed in control vs. aortic valve sclerosis (osteopontin), control vs. aortic stenosis (osteoprotegerin), and aortic valve sclerosis vs. aortic stenosis groups (MMP-2), which corresponded to valvular mRNA expression. We demonstrate distinct mRNA and protein expression underlying aortic valve sclerosis and aortic stenosis. We anticipate that extracellular matrix regulators can serve as circulating biomarkers of early calcific aortic valve disease and as novel targets for early disease mitigation, pending prospective clinical investigations.

RESUMO

Observational and randomized evidence shows that arterial grafts have better patency rates than saphenous vein grafts (SVGs) in coronary artery bypass grafting. Observational studies suggest that the use of multiple arterial grafts is associated with longer postoperative survival, but this must be interpreted in the context of treatment allocation bias and hidden confounders intrinsic to the study designs. Recently, a pooled analysis of 6 randomized trials comparing the radial artery with the SVG as the second conduit and the largest randomized trial comparing the use of single and bilateral internal thoracic arteries have provided apparently divergent results about a clinical benefit with the use of >1 arterial conduit. However, both analyses have methodological limitations that may have influenced their results. At present, it is unclear whether the well-documented increased patency rate of arterial grafts translates into clinical benefits in the majority of patients undergoing coronary artery bypass grafting. A large randomized trial testing the arterial grafts hypothesis (ROMA [Randomized Comparison of the Clinical Outcome of Single Versus Multiple Arterial Grafts]) is underway and will report the results in a few years.

RESUMO

BACKGROUND: Patients with metastatic, recurrent, or persistent cervical cancer not amenable to local control and/or distant metastases have a very poor prognosis, only being candidates for palliative-systemic therapy. First line standard treatment in this scenario is based on cisplatin/paclitaxel plus bevacizumab (GOG 240 regimen) with a short median overall survival (16.8 months) and progression-free survival (8.2 months). PRIMARY OBJECTIVE: To determine whether the addition of atezolizumab to cisplatin-paclitaxel and bevacizumab improves overall survival, compared with cisplatin-paclitaxel plus bevacizumab in patients with metastatic, recurrent, or persistent cervical cancer. STUDY HYPOTHESIS: The primary hypothesis is whether the addition of atezolizumab to cisplatin-paclitaxel and bevacizumab improves overall survival in metastatic, recurrent, or persistent cervical cancer. TRIAL DESIGN: The BEATcc study is a phase III, randomized, open-label, multi-center clinical trial. The study will be performed on an intent-to-treat population. The control arm is the administration of chemotherapy (platinum plus paclitaxel) and bevacizumab, while the experimental arm is the administration of atezolizumab in combination with the same chemotherapy regimen (1:1 randomization). The trial will be run under the ENGOT umbrella alongside JGOG and GOG-F. GEICO is the lead group on behalf of ENGOT. MAJOR INCLUSION/EXCLUSION CRITERIA: Women over 18 years old with histologically or cytologically confirmed diagnosis of squamous cell carcinoma, adenocarcinoma, or adenosquamous metastatic, recurrent, or persistent cervical cancer, not amenable for curative treatment with surgery and/or radiation therapy, will be included. Women are not eligible if they have received prior systemic anti-cancer therapy for metastatic or persistent/recurrent disease or they have disease involving the bladder or rectum at the screening/baseline pelvic magnetic resonance imaging. PRIMARY ENDPOINT: Overall survival, defined as the observed length of life from entry into the study (day of randomization) to death from any cause or the date of last contact. SAMPLE SIZE: A total of 404 patients are expected to be recruited into the study, assuming a total 10% drop-out rate. In order to test whether the experimental arm improves overall survival, the study will have 80% power using one-sided α of 0.025. There will be one interim analysis to close the study in case of early efficacy results in the experimental arm. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: The trial was launched in Q3 2018 and the trial is estimated to close in Q3 2022. We expect to be able to report mature data from the BEATcc trial by 2023. TRIAL REGISTRATION: ClinicalTrials.gov (NCT03556839).

RESUMO

AIMS: Visual estimation is the most commonly used method to evaluate the degree of coronary artery stenosis prior to coronary artery bypass grafting. In interventional cardiology, the use of fractional flow reserve (FFR) to guide revascularization decisions has become routine. We investigated whether the preoperative FFR measurement of coronary lesions is associated with anastomosis function 6 months after surgical revascularization using a multiarterial grafting strategy. METHODS AND RESULTS: In this prospective double-blind study, 67 patients were enrolled from two institutions in Europe and Canada. From these patients, 199 coronary lesions were assessed visually and with FFR at the time of the preoperative angiogram. All patients received coronary revascularization using multiple arterial grafts. A post-operative 6-month angiogram was performed to assess anastomosis functionality using a described angiographic method. The primary outcome was the association between preoperative FFR values and anastomosis function 6 months after surgery. Preoperative FFR was significantly associated with 6-months anastomotic function for all conduits and for all targets (P < 0.001). An FFR value of ≤0.78 was associated with an anastomotic occlusion rate of 3%. CONCLUSION: We found a significant association between the preoperative FFR measurement of the target vessel and the anastomotic functionality at 6 months, with a cut-off of 0.78. Integration of FFR measurement into the preoperative diagnostic workup before multiarterial coronary surgical revascularization leads to improved anastomotic graft function. CLINICAL TRIALS.

RESUMO

INTRODUCTION: the identification of a 10 cm bezoar in a hiatal hernia is unusual. Hiatal hernias are usually asymptomatic. When signs of strangulation are present the prognosis is unlucky if urgent surgical intervention is not performed. Although sometimes the prognosis is bad because of the advanced state of gastric ischemia. CASE REPORT: a 67-year-old female patient undergoing Nissen fundoplication with recurrence of hiatal hernia, volvulated and strangulated with giant bezoar inside the hhital hernia sac. DISCUSSION: despite of poor results, surgical treatment in these cases must be urgent.

RESUMO

AIMS: Mitral valve interstitial cells (MVIC) play an important role in the pathogenesis of degenerative mitral regurgitation (MR) due to mitral valve prolapse (MVP). Numerous clinical studies have observed serotonin (5HT) dysregulation in cardiac valvulopathies; however, the impact of 5HT-mediated signaling on MVIC activation and leaflet remodeling in MVP have been investigated to a limited extent. Here we test the hypothesis that 5HT receptors (5HTRs) signaling contributes to MVP pathophysiology. METHODS AND RESULTS: Diseased human MV leaflets were obtained during cardiac surgery for MVP; normal MV leaflets were obtained from heart transplants. MV RNA was used for microarray analysis of MVP patients versus control, highlighting genes that indicate the involvement of 5HTR pathways and extracellular matrix remodeling in MVP. Human MV leaflets were also studied in vitro and ex vivo with biomechanical testing to assess remodeling in the presence of a 5HTR2B antagonist (LY272015). MVP leaflets from Cavalier King Charles Spaniels were used as a naturally acquired in vivo model of MVP. These canine MVP leaflets (N=5/group) showed 5HTR2B upregulation. This study also utilized CB57.1ML/6 mice in order to determine the effect of Angiotensin II infusion on MV remodeling. Histological analysis showed that MV thickening due to chronic Angiotensin II remodeling is mitigated by a 5HTR2B antagonist (LY272015) but not by 5HTR2A inhibitors. CONCLUSION: In humans, MVP is associated with an upregulation in 5HTR2B expression and increased 5HT receptor signaling in the leaflets. Antagonism of 5HTR2B mitigates MVIC activation in vitro and MV remodeling in vivo. These observations support the view that 5HTR signaling is involved not only in previously reported 5HT-related valvulopathies, but it is also involved in the pathological remodeling of MVP.

RESUMO

BACKGROUND: Little evidence shows whether a third arterial graft provides superior outcomes compared with the use of 2 arterial grafts in patients undergoing coronary artery bypass grafting. A meta-analysis of all the propensity score-matched observational studies comparing the long-term outcomes of coronary artery bypass grafting with the use of 2-arterial versus 3-arterial grafts was performed. METHODS: A literature search was conducted using MEDLINE, EMBASE, and Web of Science to identify relevant articles. Long-term mortality in the propensity score-matched populations was the primary end point. Secondary end points were in-hospital/30-day mortality for the propensity score-matched populations and long-term mortality for the unmatched populations. In the matched population, time-to-event outcome for long-term mortality was extracted as hazard ratios, along with their variance. Statistical pooling of survival (time-to-event) was performed according to a random effect model, computing risk estimates with 95% confidence intervals. RESULTS: Eight propensity score-matched studies reporting on 10 287 matched patients (2-arterial graft: 5346; 3-arterial graft: 4941) were selected for final comparison. The mean follow-up time ranged from 37.2 to 196.8 months. The use of 3 arterial grafts was not statistically associated with early mortality (hazard ratio, 0.93; 95% confidence interval, 0.71-1.22; P=0.62). The use of 3 arterial grafts was associated with statistically significantly lower hazard for late death (hazard ratio, 0.8; 95% confidence interval, 0.75-0.87; P<0.001), irrespective of sex and diabetic mellitus status. This result was qualitatively similar in the unmatched population (hazard ratio, 0.57; 95% confidence interval, 0.33-0.98; P=0.04). CONCLUSIONS: The use of a third arterial conduit in patients with coronary artery bypass grafting is not associated with higher operative risk and is associated with superior long-term survival, irrespective of sex and diabetic mellitus status.

RESUMO

Graft failure occurs in a sizeable proportion of coronary artery bypass conduits. We herein review relevant current evidence to give an overview of the incidence, pathophysiology, and clinical consequences of this multifactorial phenomenon. Thrombosis, endothelial dysfunction, vasospasm, and oxidative stress are different mechanisms associated with graft failure. Intrinsic morphological and functional features of the bypass conduits play a role in determining failure. Similarly, characteristics of the target coronary vessel, such as the severity of stenosis, the diameter, the extent of atherosclerotic burden, and previous endovascular interventions, are important determinants of graft outcome and must be taken into consideration at the time of surgery. Technical factors, such as the method used to harvest the conduits, the vasodilatory protocol, the storage solution, and the anastomotic technique, also play a major role in determining graft success. Furthermore, systemic atherosclerotic risk factors, such as age, sex, diabetes mellitus, hypertension, and dyslipidemia, have been variably associated with graft failure. The failure of a coronary graft is not always correlated with adverse clinical events, which vary according to the type, location, and reason for failed graft. Intraoperative flow verification and secondary prevention using antiplatelet and lipid-lowering agents can help reducing the incidence of graft failure.

RESUMO

BACKGROUND: Closing the defect (CD) during laparoscopic ventral hernia repair began to be performed in order to decrease seroma, to improve the functionality of the abdominal wall, and to decrease the bulging effect. However, tension at the incision after CD in large defects is related to an increased rate of pain and recurrence. We present the preliminary results of a new technique for medium midline hernias as an alternative to conventional CD. METHODS: A prospective controlled study was conducted from January 2015 to January 2017 to evaluate an elective new procedure (LIRA) performed on patients with midline ventral hernias (4-10 cm width). The posterior rectus aponeurosis was opened lengthwise around the hernia defect using a laparoscopic approach to create two flaps and was then sutured. The size of the flaps was estimated using a mathematical formula. An on-lay mesh was placed intraperitoneal overlapping the fascia defect. The data analyzed included patient demographics, operative parameters, and complications. A computerized tomography was performed preoperatively and postoperatively (1 month and 1 year) to evaluate recurrence, distance between rectus and seroma. RESULTS: Twelve patients were included. Mean width of the defect was 5.5 cm. Average VAS (24 h) was 3.9, 1.1 (1 month), and 0 (1 year). Mean preoperative distance between rectus was 5.5 cm; postoperative was 2.2 cm (1 year). Radiological seroma at first month was detected in 50%. Mean follow-up was 15 months. CONCLUSION: The LIRA technique could be considered as an alternative to conventional CD or endoscopic component separation for medium defects under 10 cm in width. This technique obtained a "no tension" effect that could be related to a lower rate of postoperative pain with no recurrence or bulging, being a safe, feasible, and reproducible technique.

RESUMO

OBJECTIVES: To analyze the role of audiometry in considering change to a less ototoxic treatment in head and neck cancer (HNC) patients. METHODS: Consecutive patients prescribed high-dose cisplatin (100 mg/m2) between January 2013 and February 2015 were enrolled. Audiometry was performed at baseline and before cisplatin. Change to a less ototoxic agent or reduced cisplatin dose was considered with audiometric decreases >25 dB. RESULTS: A total of 103 patients were included; the median age of the patients was 59 years (range 18-75). Cisplatin was intended curative (58%), adjuvant (32%), or palliative (10%). Forty-two participants (41%) did not commence high-dose cisplatin because of baseline audiometric alterations. Of 61 patients treated with high-dose cisplatin, 40 (66%) showed marked ototoxicity at the end of treatment. The mean hearing loss between initial and final audiometries showed a hearing loss at 4 and 8 kHz in both ears (p = 0.002). Thirteen patients switched to carboplatin and 15 to a lower dose of cisplatin. The outcome was not significantly altered when cisplatin was replaced with carboplatin or cetuximab. CONCLUSIONS: Audiometric alterations are common in HNC with high-dose cisplatin, and switching to a less ototoxic regimen does not adversely affect outcome. Audiometric examination could help to prevent hearing loss in this population.

RESUMO

PURPOSE OF REVIEW: The publication of the NOBLE and EXCEL trials, with seemingly conflicting results, brought into question whether percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) is better for low-risk patients with left main coronary artery stenosis (LMCAS). This review appraises the methods and results of NOBLE and EXCEL, contextualizes them within the literature, and determines how they may affect clinical practice. RECENT FINDINGS: We appraised the trials and describe differences in methodology and results. NOBLE recruited primarily isolated LMCAS, and found that CABG was superior to PCI. EXCEL's population included patients LMCAS in the context of multivessel CAD, and found PCI and CABG were comparable. Both trials enrolled young patients with few comorbidities, and there was more protocol-mandated consistency in the procedural techniques and medical therapy of patients receiving PCI. SUMMARY: The generalizability of these trials is limited by the use of young, healthy patients at highly skilled centres that rarely reflect typical clinical practice. If these studies are to maintain relevance, trialists must address the lack of protocolization of surgical interventions and inconsistent medical therapies. Unfortunately, the limitations of NOBLE and EXCEL mean that we are no closer to answering the question of what is the optimal treatment for patients with LMCAS.

RESUMO

PURPOSE OF REVIEW: Coronary artery bypass grafting (CABG) has been regarded as the mainstream treatment for unprotected left main coronary artery (ULMCA) stenosis. However, the results of the Evaluation of XIENCE versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization (EXCEL) trial, in which percutaneous coronary intervention (PCI) was deemed noninferior to CABG, have raised a question whether the guidelines should be changed. This article provides a critical appraisal of recent randomized control trials (RCTs) on ULMCA stenosis. RECENT FINDINGS: In contrast to EXCEL trial, another large RCT named the Nordic-Baltic-British Left Main Revascularization trial showed that PCI is inferior to CABG in patients treated for ULMCA stenosis. The reason for the discrepancy between these two RCTs may be due to differences in study design. In EXCEL trial, the adoption of new periprocedural myocardial infarction definition, the noninclusion of target vessel revascularization as a primary endpoint component, and the timeline of the study may have helped claim that PCI is noninferior to CABG. SUMMARY: The long-term efficacy of PCI for ULMCA stenosis has not yet been demonstrated. Further studies and follow-up data are needed before the indications for PCI are expanded in this scenario.
