Callander JK, Souza SS, Eltawil Y, El-Sayed IH, George JR, Ha P, Ryan WR, Xu MJ, Heaton CM. Prognostic risk factors of buccal squamous cell carcinoma: A case-control study. Head Neck 2024. [PMID: 38411290 DOI: 10.1002/hed.27705] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 01/30/2024] [Accepted: 02/13/2024] [Indexed: 02/28/2024] Open
Abstract
OBJECTIVES To describe the clinicopathologic presentation of buccal squamous cell carcinoma and identify risks factors for recurrence and overall survival. METHODS This is a retrospective case-control study of patients with oral cavity squamous cell carcinoma (OCSCC) treated at a single tertiary care center between 2010 and 2022. All patients with buccal subsite OCSCC treated during this time frame were included and paired with a randomly selected age and gender matched patient with non-buccal OCSCC. Relevant data was collected via chart review. RESULTS Seventy-seven patients with buccal SCC were matched with 77 non-buccal OCSCC controls. The median follow-up time was 27 months (IQR 14-61). Median age was 67 years (IQR 57-75) and 53% of the cohort was female. Twenty (26%) buccal SCC patients experienced a recurrence versus 19 (25%) in the controls. Age ≥65-years-old increased odds of all-cause mortality in the buccal SCC group, but not in the control group. Perineural invasion and positive margins increased odds of recurrence in the buccal group only. Overall survival and progression-free survival did not differ between the groups, despite a greater number of T2 buccal tumors and T1 non-buccal tumors. CONCLUSIONS Buccal SCC presents at a higher T stage than other oral cavity SCC subsite and may exhibit variance in the pathologic risk factors that predict poor outcomes versus non-buccal OCSCC. Despite these relatively minor differences, however, oncologic outcomes between these groups were similar.

Abstract
In India, oral cancers are the major cause of cancer-related death. Tongue and buccal mucosa being the major subsites in oral cancer have varying clinicopathological presentations. This study is intended to know the difference in clinicopathological behavior of these two subsites. This retrospective study included 474 patients of which 232 patients had tongue cancer and 242 patients had buccal alveolar complex (BAC) cancer. Comparison between the pathological characters including pattern of nodal involvement was analyzed. Disease-free survival (DFS) and factors influencing the DFS were analyzed and compared using Cox regression analysis. Mean age of the study population was 52.7 years. Tongue oral squamous cell carcinoma (OSCC) differed significantly from BAC OSCC in terms of age of presentation, tumor staging, and perineural invasion. Among neck nodal involvement, tongue OSCC commonly involved level IIa (p < 0.001) whereas BAC involved level Ib (p < 0.001). At a median follow-up of 27 months, 141 patients had disease recurrence, tongue OSCC commonly recurred in neck (p = 0.008), and BAC OSCC relapsed at primary site (p = 0.001). Patients older than 45 years with BAC cancer had lesser risk of recurrence (HR, 0.30; 95% CI, 0.2-0.5; p < 0.0001). Pathological tumor stage in tongue cancer (HR, 14.9; 95% CI, 2.6-84.8; p = 0.002) and grade of tumor differentiation in BAC OSCC (HR, 9.2; 95% CI, 1.9-43.3; p < 0.005) were the most significant factors that influenced tumor recurrence. There was a significant difference in factors influencing disease recurrence among tongue and BAC OSCC. Also, pattern of nodal metastasis and pattern of recurrence were different. Hence, further research on OSCC may be done site specific. Supplementary Information The online version contains supplementary material available at 10.1007/s13193-023-01750-8.

Abstract
Oral cavity squamous cell carcinoma (OSCC) is a leading cause of death in Taiwan. Most of the patients in the literature are male. The risk factors, cancer characteristics, and treatment outcomes were investigated in female patients and compared with male patients in this study.This retrospective study recruited 2046 OSCC patients between 1995 and 2019. The age, tumor subsites, and survival were reviewed and recorded. Overall survival and disease-free survival were the main outcomes.Female patients represented 6.7% of the entire study cohort. Females were diagnosed at an older age and an earlier local stage than male patients (P < .001). Female patients were less exposed to cigarettes, alcohol, and betel-quid (all P < .001). The tongue (55.1%) was the most frequent subsite in females, while the buccal cavity (38.4%) and the tongue (35.3%) were more likely (P < .001) to be associated with the male gender. Female patients in the tongue cancer subgroup presented less frequently with extra-nodal extension compared with male patients (P = .040). No significant differences in recurrence or overall deaths were observed between the genders during the follow-up period.The OSCC male to female ratio in Taiwan was 14:1. Female OSCC occurred more frequently on the tongue, and was diagnosed at an older age and at an earlier tumor stage than in male patients. No survival difference was found between female and male OSCC patients.

Abstract
Background: The aim of this study was to make a comparison of clinicopathological characteristics of oral leukoplakia between male and female patients following carbon dioxide laser excision for oral leukoplakia and analyze the factors associated with the treatment outcomes in female patients. Methods: Medical records of patients with oral leukoplakia receiving laser surgery from 2002 to 2020 were retrospectively reviewed and analyzed statistically. Results: A total of 485 patients were enrolled, including 412 male (84.95%) and 73 female (15.05%). Regarding the locations, the predilection site of oral leukoplakia in male patients was buccal mucosa (p = 0.0001) and that for women patients was tongue (p = 0.033). The differences of recurrence and malignant transformation between both sexes were not significant (p > 0.05). Among female patients, area of oral leukoplakia was the risk factor related to recurrence (p < 0.05). Clinical morphology and postoperative recurrence were the risk factors related to malignant transformation (p < 0.05). Conclusions: In comparison with male patients, there was no significant difference of the postoperative recurrence and malignant transformation of oral leukoplakia in female patients. Among the female patients, clinicians should pay more attention to large-sized and non-homogeneous leukoplakia, and postoperative recurrent lesions.

Abstract
BACKGROUND The aim of this study is to assess the feasibility and effectiveness of using peri-operative brachytherapy (BRTx) for positive/narrow margins present post primary surgical resection of oral tongue squamous cell carcinoma (OTSCC). METHODS Prospective single-centre study of patients with OTSCC (T1-3, N0-3, M0) treated with resection of primary tumour ± regional nodal resection and intra-operative insertion of BRTx catheters. BRTx was administered twice daily at 40.8Gy/12Fr for 'Positive' (≤2 mm) margins, at 34Gy/10Fr for 'Narrow' (2.1-5 mm) margins, and not given for 'Clear' (> 5 mm) margins over the course of 5-6 days, 3-5 days post operatively. RESULTS Out of 55 patients recruited 41 patients (74.6%) were treated with BRTx, as 12 patients had clear margins and 2 patients had unfavourable tumour anatomy for catheter insertion. EBRTx was avoided in 64.3% of patients. Overall Survival (OS) at 3 and 5 years was 75.6 and 59.1% respectively, while Disease Specific Survival (DSS) was 82.3 and 68.6% at 3 and 5 years respectively. Recurrence and survival outcomes were not associated with margin status or the use of or specific dose of BRTx on Cox regression analysis. Acute and late toxicity secondary to BRTx was minimal. CONCLUSIONS The use of BRTx after primary OTSCC resection with positive/narrow margins ± EBRTx to the neck ± CTx achieves outcomes comparable to traditional treatment of surgery followed by re-resection or EBRTx ± CTx. Morbidity associated with oral cavity EBRTx or secondary resection and reconstruction is thus avoided. Both acute and late toxicity rates are low and compare favourably with other BRTx OTSCC studies.

Abstract
Background Our goal was to clarify the comparison between elective neck dissection (END) and the wait-and-see policy in neck management for cT1N0 buccal squamous cell carcinoma (SCC). Methods This was a retrospective comparison of 175 prospectively enrolled patients with cT1N0 buccal SCC. The patients were divided into two groups based on the nonrandomized management of the neck: 125 patients received END, and 50 patients were exposed to the wait-and-see policy. The main study endpoints were locoregional control (LRC) and disease-specific survival (DSS). Patients were asked to complete the shoulder domain in the University of Washington quality of life questionnaire, version 4, 1 year postoperatively. Results Ten of the patients undergoing END developed recurrence, and the 5-year LRC rate was 92%. Five patients undergoing the wait-and-see policy developed recurrence, and the 5-year LRC rate was 90%. The difference was not significant (p = 0.668). There were 6 deaths in patients undergoing END, and the 5-year DSS rate was 94%. There were 3 deaths in patients undergoing the wait-and-see policy, and the 5-year DSS rate was 94%; the difference was not significant (p = 0.777). The mean shoulder scores of patients undergoing END and the wait-and-see policy were 93.9 and 100, respectively, and the difference was not significant (p = 0.284). Conclusion Elective neck dissection does not carry a survival benefit compared to the wait-and-see policy, and it is not suggested for patients with cT1N0 buccal SCC.

Abstract
BACKGROUND Oral squamous cell carcinoma (OSCC) leads to thousands of deaths every year in Taiwan. Nearly 40% of OSCC patients are diagnosed with stage IV disease, which has a poor prognosis. Multimodality treatments including surgery and adjuvant therapy have been utilized, but their treatment outcomes are generally poor. In this study, we sought to identify possible clinical impact factors that may contribute to the survival of stage IV OSCC. METHODS Data for patients with malignant neoplasms of the oral cavity registered in the Cancer Registry Database of Taipei Veterans General Hospital between 2002 and 2011 were retrieved. The study patients consisted of OSCC patients with clinical stage IV disease who had undergone a surgery and adjuvant therapy. The primary endpoints were the 5-year disease-free survival (DFS) and overall survival (OS) rates. The clinicopathological characteristics of the patients were also stratified and compared. RESULTS A total of 191 OSCC patients were included for retrospective analysis. The different subgroups of stage IV disease presented different treatment outcomes. The 5-year OS versus DFS rates of each subgroup were as follows: T4N0: 70.9% versus 52.6%; T1-3N23: 66.1% versus 49.8%; T4N1: 49.6% versus 31.6%; and T4N23: 40.9% versus 31.0% (p < 0.01). Patients with diabetes, moderate or poor cell differentiation, perineural invasion, and extracapsular spread presented lower 5-year OS rates (hazard ratio [HR] = 1.87, 1.65, 2.42, and 2.14, respectively), and patients with perineural invasion, positive cut margin, and extracapsular spread presented lower 5-year DFS rates (HR = 1.57, 1.62, and 1.71, respectively). CONCLUSION In this study, we elucidated the different survival rates of different subgroups of stage IV OSCC following the same treatment scheme. The results of the study provide clinical physicians with references by which to evaluate prognosis and determine post-operative disease monitoring timetables based upon different characteristics.

Abstract
The clinical characteristics of oropharyngeal squamous cell carcinoma (OPSCC) may be different between endemic and non-endemic regions of betel nut chewing. The impact of combined alcohol drinking/betel quid chewing/cigarette smoking (ABC) exposure on the survival of OPSCC remains unclear. We reviewed the medical records of OPSCC patients between 1999 and 2013. Immunohistochemical staining of p16 and HPV genotype detection by DNA Polymerase chain reaction were both performed for each tumor. A total of 300 eligible patients including 74 HPV+ OPSCC patients and 226 HPV− OPSCC patients were enrolled. The 5-year disease-free survival rates for the HPV−, HPV+ OPSCC with and without ABC patients were 49.8%, 58.4% and 94%, respectively. The 5-year overall survival rates for the patients with HPV−, HPV+ OPSCC with and without ABC patients were 46%, 57.4% and 86%, respectively. Advanced locoregionally disease (T3/T4, N2/N3), HPV- OPSCC, combined 2 or all ABC exposure were the independent adverse prognostic factors for disease-free and overall survival. Therefore, our data suggest that in an endemic region of betel quid chewing, HPV− OPSCC comprises the majority of OPSCC and has a worse survival. Combined 2 or all ABC exposure had a significant negative impact on disease-free and overall survival.

BACKGROUND The associations between malignant transformation of oral potentially malignant disorders (OPMDs), oral cancer development and prognosis, and apurinic/apyrimidinic endonuclease 1 (APE1) functional polymorphisms are unclear. METHODS Patients with OPMDs, patients with oral cancer, and healthy controls from the community were recruited to determine the effects of APE1 polymorphisms on malignant transformation, overall survival, and genetic susceptibility, respectively. RESULTS The APE1 Asp148Glu polymorphisms significantly correlated with a high hazard ratio for OPMD malignant transformation (adjusted hazard ratio [AHR] = 2.29; 95% confidence interval [CI] = 1.44-3.74) and low overall survival in oral cancer patients (AHR = 1.71, 95% CI = 1.11-2.56) according to follow-up and survival analysis. However, APE1 polymorphisms did not significantly correlate with development of oral cancer in the case-control study and logistic regression analysis. CONCLUSIONS These results indicate that APE1 Asp148Glu polymorphisms may have indirect roles in increasing the OPMD malignant transformation rate and in decreasing overall survival in oral cancer patients.
