Cutaneous squamous cell carcinoma is not uncommon in patients affected by malignant lymphoma, mostly in elderly; the contemporary management of these diseases presents some difficulties, since they require different modalities of treatment. Only small case series and single case report are described in literature about synchronous or metachronous metastatic cutaneous cell carcinoma and lymphoma/chronic lymphocytic leukaemia; in addiction, we report our experience in order to illustrate difficulties encountered in the management of these patients. We conclude that these patients need a close follow-up, and that US-guided FNAC and 18F-fluorodeoxyglucose PET in addiction to MRI are useful for staging. cSCC, having a poorer prognosis, has to be treated first; nevertheless, mortality in these patients is obviously higher than expected in immunocompetent people.
皮肤鳞状细胞癌在恶性淋巴瘤患者中并不少见,多见于老年人;这些疾病的当代管理存在一些困难,因为它们需要不同的治疗方式。文献中只报道了同步或异时性转移性皮肤细胞癌和淋巴瘤/慢性淋巴细胞白血病的小病例系列和单例报告;在成瘾,我们报告我们的经验,以说明在这些病人的管理遇到的困难。我们的结论是,这些患者需要密切随访,美国引导的FNAC和18f -氟脱氧葡萄糖PET对MRI成瘾的分期是有用的。cSCC预后较差,必须先治疗;然而,这些患者的死亡率明显高于免疫功能正常人群的预期。

The increasing incidence and complexity of oral cancers demand advancements in both diagnostic precision and individualized treatment strategies. This study investigates the application of artificial intelligence (AI), particularly through deep learning and machine learning models, to enhance diagnostic accuracy and support personalized treatment planning in oral oncology. Recent advancements in AI-driven diagnostics, particularly using Convolutional Neural Networks (CNNs) and Vision Transformers (ViTs), have significantly improved early detection and treatment prediction for oral cancer. By integrating datasets from medical imaging, clinical records, and histopathological profiles, our AI-driven models achieved a diagnostic accuracy of 93 %, with a sensitivity of 91 % and specificity of 94 %, surpassing traditional diagnostic approaches. Furthermore, our treatment prediction models, employing patient-specific tumour characteristics and clinical variables, demonstrated an 87 % accuracy in forecasting optimal therapeutic responses, effectively tailoring treatment strategies to individual patients. These findings underscore AI's transformative potential in oral oncology, providing a foundation for improved patient outcomes and paving the way for future innovations in personalized medicine, as highlighted by recent studies in the field.

Margin assessment during transoral robotic surgical (TORS) resections of head and neck mucosal malignancies can be complex, originating in part from discrepancies in definitions of positive or close margins, and the technical difficulty of revising microscopic margins intraoperatively without incurring the functional consequences associated with soft tissue deficits in the oropharynx and larynx. Intraoperative optical imaging modalities, including confocal laser endomicroscopy (CLE), may represent an alternative or adjunctive option to delineate tumor footprint and assess for peripheral margin status. We present a case series describing our use of the Cellvizio® probe-based CLE platform as an intraoperative modality to assess for peripheral mucosal margins in the larynx, oropharynx, and hypopharynx during TORS resections using robotic instrumentation to establish basic feasibility and create the groundwork for future investigations of relative efficacy and impact on local recurrence rates.
在经口机器人手术(TORS)切除头颈部粘膜恶性肿瘤时,边缘评估可能是复杂的,部分原因是由于对正缘或近缘的定义存在差异,以及术中修改显微边缘而不引起口咽和喉部软组织缺损相关功能后果的技术困难。术中光学成像方式,包括共聚焦激光内镜(CLE),可能是描述肿瘤足迹和评估外周边缘状态的替代或辅助选择。我们提出了一个病例系列,描述了我们使用基于Cellvizio®探针的CLE平台作为术中方式,在使用机器人仪器进行TORS切除术期间评估喉、口咽和下咽的周围粘膜边缘,以建立基本的可行性,并为未来研究相对疗效和对局部复发率的影响奠定基础。

Duplication of the internal jugular vein is a rare anatomic variation that may occasionally be encountered during neck surgeries. This anomaly presents as two separate internal jugular veins instead of the typical single vein. Understanding and recognizing this variability is critical for surgeons to avoid unwanted injury and ensure a successful surgical outcome. The objective of this case report to understand the variation in anatomy of internal jugular vein, explain the presentation of internal jugular vein duplication, emphasizes the importance of careful dissection techniques when anatomical abnormalities are encountered during neck surgery and to discuss literature and hypothesis pertaining to its embryology of internal jugular vein duplication.
颈内静脉重复是一种罕见的解剖变异,在颈部手术中偶尔会遇到。这种异常表现为两条独立的颈内静脉,而不是典型的单一静脉。了解和认识这种可变性对外科医生避免不必要的伤害和确保手术成功至关重要。本病例报告的目的是了解颈内静脉的解剖变化,解释颈内静脉重复的表现,强调在颈部手术中遇到解剖异常时仔细解剖技术的重要性,并讨论有关颈内静脉重复的胚胎学的文献和假设。

Oral cancer remains a significant global health issue, often diagnosed late due to limitations in traditional diagnostic methods. This study explores the application of artificial intelligence (AI) and machine learning (ML) to enhance the early detection and diagnosis of oral cancer. We investigated three data cleaning techniques missing value imputation, outlier detection, and normalization and assessed their impact on model performance. Using convolutional neural networks (CNNs), support vector machines (SVMs), and random forests, we compared the effectiveness of these techniques in improving diagnostic accuracy and mean squared error (MSE). The results demonstrated that normalization, specifically min-max scaling, was the most effective method, leading to the highest accuracy (94 %) and the lowest MSE (0.013) for CNN models. Outlier detection also improved performance, achieving 93 % accuracy and an MSE of 0.014, while missing value imputation resulted in a lower accuracy of 92 % and an MSE of 0.015. These findings underscore the importance of normalization in preprocessing for machine learning models, highlighting its role in achieving superior performance in oral cancer detection. This study underscores the potential of AI-driven methods to revolutionize diagnostic practices, offering more accurate and timely detection of oral cancer.
口腔癌仍然是一个重大的全球健康问题,由于传统诊断方法的限制,往往诊断较晚。本研究探讨人工智能(AI)和机器学习(ML)在提高口腔癌早期发现和诊断中的应用。我们研究了三种数据清理技术缺失值输入、离群值检测和归一化,并评估了它们对模型性能的影响。使用卷积神经网络(cnn)、支持向量机(svm)和随机森林,我们比较了这些技术在提高诊断准确性和均方误差(MSE)方面的有效性。结果表明,归一化,特别是最小-最大缩放,是最有效的方法,导致CNN模型的最高准确率(94%)和最低MSE(0.013)。离群值检测也提高了性能,达到93%的准确率和0.014的MSE,而缺失值输入导致较低的准确率为92%,MSE为0.015。这些发现强调了归一化在机器学习模型预处理中的重要性,强调了其在口腔癌检测中实现卓越性能的作用。这项研究强调了人工智能驱动的方法在彻底改变诊断实践方面的潜力,提供更准确和及时的口腔癌检测。

Importance

There is a lack of evidence-based recommendations for patient work up, counseling, and management for mucoepidermoid carcinoma of the oropharynx (OPMEC).

Objective

We aim to summarize the published data on OPMEC and report the demographics, clinical presentation, histology, treatment strategies, and oncologic outcomes in OPMEC.

Methods

A comprehensive medical librarian-led systematic search was conducted of multiple comprehensive databases according to PRISMA guidelines. We searched for articles published through July 7, 2023, and updated the search on February 27, 2024. This was supplemented by a manual search on PubMed and of the bibliographies of included manuscripts. Review articles, national database studies, abstracts and studies not reporting on primary OPMEC were excluded. Inclusion criteria included human studies, population >18 years, peer-reviewed articles, English language, and reports including data of interest for patients with primary OPMEC. The review was conducted by two independent reviewers (GAC and AEB) and conflicts were resolved by the senior author (KMV). Findings were summarized and descriptive statistics were reported.

Results

Twenty-six publications – 2 case series and 24 case reports - describing 80 patients were included. Patients were predominantly female (30/54, 55.6 %) with a median age of 53 years (range: 19–88). OPMEC was most common in the base of tongue (41/54, 75.9 %) and most patients had an oropharyngeal mass noted on examination. Tumors were frequently T1/2 when reported (27/37, 72.9 %). Histological grade was most commonly intermediate grade (31/80, 38.7 %). There were 34 reports of nodal involvement. 21 cases reported both nodal involvement and grade, 5 of which were low grade, 10 intermediate grade, and 6 high grade primary tumors. The most commonly reported treatment modality was surgery alone (15/29, 51.7 %) or surgery with adjuvant radiotherapy (10/29, 34.4 %). 55.0 % (11/20) had positive margins on final pathology. Follow-up length varied (Range 75–146 months) and the overall survival was 85.0 %, with two unrelated deaths and one death likely attributed to OPMEC. Only one publication including 26 cases of OPMEC reported cancer specific survival outcomes, with 75 % 5-year and 65 % 10-year overall survival, and 86 % 5-year and 86 % 10-year distant metastases-free-survival.

Conclusions

OPMEC most often presents in females in their 50's as a base of tongue mass and has a high potential for nodal metastasis despite low or intermediate grading. Oncologic outcomes appear to be favorable following surgery with or without adjuvant therapy. Further research is needed to develop an evidence-based treatment strategy for patients with OPMEC.
对于口咽部粘液表皮样癌(OPMEC)的患者检查、咨询和治疗,目前缺乏循证建议。目的总结已发表的OPMEC数据,报告OPMEC的人口统计学、临床表现、组织学、治疗策略和肿瘤预后。方法以医学图书馆员为主导,按照PRISMA指南对多个综合数据库进行系统检索。我们搜索了2023年7月7日之前发表的文章,并在2024年2月27日更新了搜索。这是由PubMed上的人工搜索和包括手稿的参考书目补充。综述文章、国家数据库研究、摘要和未报道原发性OPMEC的研究被排除在外。纳入标准包括人类研究、18岁人群、同行评议文章、英语语言和包括原发性OPMEC患者相关数据的报告。审评由两位独立审稿人(GAC和AEB)进行,冲突由资深作者(KMV)解决。总结研究结果并进行描述性统计。结果共纳入文献26篇,病例系列2篇,病例报告24篇,共80例患者。患者以女性为主(30/54,55.6%),中位年龄53岁(范围:19-88岁)。OPMEC最常见于舌底(41/54,75.9%),大多数患者在检查时发现口咽肿块。肿瘤常为T1/2(27/37, 72.9%)。组织学分级多为中度(31/80,38.7%)。有34例淋巴结受累。21例报告了淋巴结受累和分级,其中5例为低级别,10例为中级,6例为高级别原发肿瘤。最常见的治疗方式是单纯手术(15/29,51.7%)或手术加辅助放疗(10/29,34.4%)。55.0%(11/20)的患者最终病理切片呈阳性。随访时间各不相同(75-146个月),总生存率为85.0%,有2例无关死亡,1例可能归因于OPMEC。只有一篇包括26例OPMEC病例的出版物报道了癌症特异性生存结果,5年和10年总生存率分别为75%和65%,5年和10年无远处转移生存率分别为86%和86%。结论sopmec多见于50多岁的女性,作为舌肿块的基底,尽管分级低或中等,但淋巴结转移的可能性很高。无论是否进行辅助治疗,肿瘤预后似乎都是有利的。为OPMEC患者制定循证治疗策略需要进一步研究。

There were 34 reports of nodal involvement. 21 cases reported both nodal involvement and grade, 5 of which were low grade, 10 intermediate grade, and 6 high grade primary tumors. The most commonly reported treatment modality was surgery alone (15/29, 51.7 %) or surgery with adjuvant radiotherapy (10/29, 34.4 %). 55.0 % (11/20) had positive margins on final pathology. Follow-up length varied (Range 75–146 months) and the overall survival was 85.0 %, with two unrelated deaths and one death likely attributed to OPMEC. Only one publication including 26 cases of OPMEC reported cancer specific survival outcomes, with 75 % 5-year and 65 % 10-year overall survival, and 86 % 5-year and 86 % 10-year distant metastases-free-survival.</div></div><div><h3>Conclusions</h3><div>OPMEC most often presents in females in their 50's as a base of tongue mass and has a high potential for nodal metastasis despite low or intermediate grading. Oncologic outcomes appear to be favorable following surgery with or without adjuvant therapy. Further research is needed to develop an evidence-based treatment strategy for patients with OPMEC.</div></div>","PeriodicalId":94378,"journal":{"name":"Oral Oncology Reports","volume":"13 ","pages":"Article 100695"},"PeriodicalIF":0.0,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143145764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The advent of AI-assisted writing tools, such as ChatGPT, has generated significant debate within scientific communities, primarily regarding their influence on the rigor and integrity of academic writing. While critics argue that reliance on these tools could dilute analytical depth or introduce biases, a balanced perspective suggests that AI-driven writing can enhance clarity, structure complex arguments, and improve the efficiency of scientific communication. This manuscript addresses the controversies surrounding AI writing by analyzing historical precedents of methodological errors in published research, highlighting the need for error-minimizing tools during manuscript preparation. Case studies of notable retractions and methodological critiques reveal that inaccuracies in scientific literature are not unique to the era of AI. These issues underscore the need for stringent ethical practices and critical evaluation, regardless of technological advancements. AI writing tools, when employed responsibly, serve as valuable assets to researchers by supporting precision and transparency in scholarly communication. Thus, embracing AI tools, rather than demonizing them, may contribute positively to the goals of reproducibility and trustworthiness in academic publications. Ethical guidelines and a commitment to integrity remain paramount as these tools evolve.
人工智能辅助写作工具的出现,如ChatGPT,在科学界引起了重大争论,主要是关于它们对学术写作的严谨性和完整性的影响。尽管批评人士认为,依赖这些工具可能会稀释分析深度或引入偏见,但一个平衡的观点表明,人工智能驱动的写作可以提高清晰度,构建复杂的论点,并提高科学交流的效率。本文通过分析已发表研究中方法论错误的历史先例,解决了围绕人工智能写作的争议,强调了在手稿准备过程中需要尽量减少错误的工具。对著名撤稿和方法论批评的案例研究表明,科学文献中的不准确性并非人工智能时代所独有。这些问题强调了严格的道德实践和批判性评估的必要性,无论技术进步如何。当负责任地使用人工智能写作工具时,通过支持学术交流的准确性和透明度,它可以成为研究人员的宝贵资产。因此,拥抱人工智能工具,而不是妖魔化它们,可能会对学术出版物的可重复性和可信赖性目标做出积极贡献。随着这些工具的发展,道德准则和对诚信的承诺仍然是最重要的。
