ABSTRACT
Objectives: Lymph node metastasis (LNM) is the most significant parameter affecting overall survival in patients with oral cavity squamous cell carcinomas (OCSCC). Elective neck dissection (END) is the standard of care in the early management of OCSCC with a depth of invasion (DOI) greater than 2-4 mm. However, most patients show no LNM in the final pathologic report, indicating overtreatment. Thus, more detailed indicators are needed to predict LNM in patients with OCSCC. In this study, we critically evaluate the existing literature about the risk of different histological parameters in estimating LNM. Methods: A systematic review was conducted using PRISMA guidelines. PubMed, Web of Science, Cochrane, and Scopus were searched from inception to December 2023 to collect all relevant studies. Eligibility screening of records was performed, and data extraction from the selected studies was carried out independently. Inclusion in our systematic review necessitated the following prerequisites: Involvement of patients diagnosed with OCSCC, and examination of histological parameters related to lymph node metastasis in these studies. Exclusion criteria included animal studies, non-English articles, non-availability of full text, and unpublished data. Results: We included 217 studies in our systematic review, of which 142 were eligible for the meta-analysis. DOI exceeding 4 mm exhibited higher risk for LNM [Risk ratio (RR) 2.18 (1.91-2.48), p<0.00001], as did perineural invasion (PNI) [RR 2.04 (1.77-2.34), p<0.00001], poorly differentiated tumors [RR 1.97 (1.61-2.42), p<0.00001], lymphovascular invasion (LVI) [RR 2.43 (2.12-2.78), p<0.00001], groups and single pattern of invasion [RR 2.47 (2.11-2.89), p<0.00001], high tumor budding [RR 2.65 (1.99-3.52), p<0.00001], tumor size over 4 cm [RR 1.76 (1.43-2.18), p<0.00001], tumor thickness beyond 4 mm [RR 2.72 (1.91-3.87), p<0.00001], involved or close margin [RR 1.73 (1.29-2.33), p = 0.0003], and T3 and T4 disease [RR 1.98 (1.62-2.41), p <0.00001]. Conclusion: Our results confirm the potential usefulness of many histopathological features in predicting LNM and highlight the promising results of others. Many of these parameters are not routinely incorporated into pathologic reports. Future studies must focus on applying these parameters to examine their validity in predicting the need for elective neck treatment.
ABSTRACT
BACKGROUND: Otorhinolaryngology (ORL) specialists treat patients of different ages, ranging from elderly patients with head and neck tumors to neonates with respiratory problems. No studies have been conducted to explore the factors that affect the preference for ORL among Umm Al-Qura University students. We aimed to investigate factors and motivators influencing medical students at Umm Al-Qura University in Makkah, Saudi Arabia, who choose to pursue a career in ORL-head and neck surgery. METHODS AND MATERIALS: This cross-sectional study was conducted over two months in 2023 among 439 students in the pre-clinical, clinical, and internship years of the Faculty of Medicine at Umm Al-Qura University, Saudi Arabia. We shared a Google Forms questionnaire (Google, Inc., Mountain View, CA) and explored factors associated with interest in ear, nose, and throat (ENT) as a future specialty. We used Pearson's chi-square test to arrive at the results. RESULTS: A total of 339 (77.2%) participants were female. Participants were evenly divided between pre-clinical years (213 (48.5%)) and clinical years (207 (47.2%)), with a smaller percentage in the internship category (19 (4.3%)). ORL involvement was reported in 159 (36.2%) of the participants. CONCLUSION: The surgical specialty of ORL focuses mostly on conditions affecting the head, neck, nose, and ears. Since students found this specialty fascinating, we recommend that senior doctors make a greater effort to enlighten doctors-in-training about this field of expertise through lectures and campaigns at hospitals and universities.
