Abstract
OBJECTIVE To analyze the impact of clinico-pathological prognostic factors on survival in patients with GBC OSCC. To evaluate the association between various clino-pathological and treatment factors influencing the 3-year and 5-year Overall survival (OS), and Disease specific survival (DSS) in patients with lower GBC OSCC. PATIENTS & METHODS An Institutional Ethical Committee (IEC) approved retrospective chart audit was performed. Biopsy proven squamous cell cancer of gingivobuccal complex (GBC OSCC) patients from 2010 to 2019 who were treated primarily with surgery with or without adjuvant therapy having complete clinicopathological and follow up data were included. Survival outcomes including 2-year, 3-year & 5-year OS, and DSS were calculated and analyzed. A multivariate analysis was performed to identify significant predictor for the survival outcomes. A p-value < 0.05 was considered significant. RESULTS 183 patients with primary OSCC were identified out of which 83 patients comprised of OSCC of lower GBC. Age (p < 0.001), tumor grade (p = 0.009), pN status (p = 0.002), PNI (p < 0.001), lymph node metastasis (p = 0.002), treatment given (p = 0.02) and adjuvant therapy (p = 0.02) were found as a significant prognostic factor in univariate analysis. CONCLUSION The OS & DSS of the patients with lower GBC SCC is 78.3%. The 2-year, 3-year, and 5-year OS of the study population was reported to be 95.2%, 87.9%, and 78.8% respectively. PNI & lymph node metastasis were significant prognostic factor for OS with an adjusted hazard ratio 4.91 and 7.75 respectively.

Abstract
Buccal squamous cell carcinoma (SCC) appears to behave more aggressively than other oral subsites, in particular with regards to regional disease at presentation and regional recurrence. Adequate management of the neck is of the utmost importance but is still the subject of debate. An international multicentre retrospective review of 101 patients treated for T1-T2 buccal SCC was performed. Twenty-four were staged clinical node positive (cN+) and underwent therapeutic neck dissection, while 77 were node negative (cN0), with 32 undergoing elective neck dissection (END), with an occult nodal metastasis rate of 28.1%. Depth of invasion (DOI) < 4 mm was associated with a significantly lower rate of cervical nodal metastasis (87.5% versus 12.5%; P = 0.033). END demonstrated a non-significantly lower regional recurrence rate compared to observation (6.3% versus 8.9%, P = 0.670). Regional recurrence was more common in pN+ (24%) and undissected cases (8.9%) than in pN0 patients (0%) (P = 0.011) and was associated with DOI > 5 mm (P = 0.002). Regional recurrence resulted in a reduction in survival (24 versus 93 months, P < 0.001). In the pT2cN0 group, END improved survival (123 versus 26 months, P = 0.009). It is suggested that END be performed in cT2N0 buccal SCC, particularly for tumours with DOI > 4 mm.

Cancer Med 2024; 13:e6907. [PMID: 38284829 PMCID: PMC10905535 DOI: 10.1002/cam4.6907] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 11/29/2023] [Accepted: 12/21/2023] [Indexed: 01/30/2024] Open
Abstract
OBJECTIVE Buccal mucosa cancer (BMC) is one of the most common oral cancers and has poor prognosis. The study aimed to develop and validate nomograms for predicting the 1-, 3-, and 5-year overall survival (OS) and cancer-specific survival (CSS) of BMC patients. METHODS We collected and reviewed information on BMC patients diagnosed between 2004 and 2019 from the Surveillance Epidemiology and End Results database. Two nomograms were developed and validated to predict the OS and CSS based on predictors identified by univariate and multivariate Cox regression. An extra external validation was further performed using data from Sun Yat-sen Memorial Hospital (SYSMH). RESULTS A total of 3154 BMC patients included in this study were randomly assigned to training and validation groups in a 2:1 ratio. Independent prognostic predictors were identified, confirmed, and fitted into nomograms for OS and CSS, respectively. The C-indices are 0.767 (Training group OS), 0.801 (Training group CSS), 0.763 (Validation group OS), and 0.781 (Validation group OS), respectively. Moreover, the nomograms exhibited remarkable precision in forecasting and significant clinical significance, as evidenced by receiver operating characteristic (ROC) curves, calibration curves, and decision curve analyses (DCA). The final validation using our data from SYSMH also showed high accuracy and substantial clinical benefits within the nomograms. The C-indices are 0.849 (SYSMH group OS) and 0.916 (SYSMH group CSS). These indexes are better than tumor, node, and metastasis stage based on prediction results. CONCLUSIONS The nomograms developed with great performance predicted 1-, 3-, and 5-year OS and CSS of BMC patients. Use of the nomograms in clinical practices shall bring significant benefits to BMC patients.

Abstract
Objective Currently, there is no up-to-date guideline for the treatment of buccal mucosal squamous cell carcinoma (BMSCC) in the Netherlands. A questionnaire was used to investigate the opinions of Dutch head and neck surgeons on BMSCC of the cheek treatment. Methods A questionnaire was sent to all 91 head and neck surgeons in the Netherlands. Their opinions on surgical tumor-free margins, through-and-through defects, and indications for local adjuvant therapy were questioned. Results The response rate was 51%. To prevent a through-and-through defect, 67% of the surgeons would accept a deep clinical (macroscopic) margin of ≤5 mm. The less adverse histological characteristics a tumor has, the less consensus there is amongst the surgeons for local adjuvant treatment in case of close margins. Conclusion There is no consensus amongst Dutch head and neck surgeons about the optimal treatment for BMSCC of the cheek. There are different opinions on acceptable resection margins, indications for a through-and-through defect, and indications for adjuvant treatment. BMSCC of the cheek treatment should be more uniform and less surgeon dependent. Level of evidence N/A.

Application of anatomy unit resection surgery for lateral basicranial surgical approach in oral squamous carcinoma. BMC Oral Health 2023; 23:9. [PMID: 36611157 PMCID: PMC9826594 DOI: 10.1186/s12903-023-02708-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Accepted: 01/03/2023] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND The basicranial region lacks definite boundaries and includes various anatomical units. We developed a novel concept of the posterior oral anatomical complex (POAC) to identify these anatomical units in the basicranial region. OSCC with POAC involvement is termed posterior oral squamous cell carcinoma (POSCC) with poor prognosis. The principal aim of this study was to evaluate the effect of anatomy unit resection surgery (AUSR) on patients with POSCC. METHODS A total of 120 POSCC patients who underwent radical surgical treatment were recruited for this study. These POSCC patients were treated with conventional surgery or AUSR. According to the extent of primary tumor resection in the AUSR group, the lateral basicranial surgical approach can be subdivided into four types: face-lateral approach I, face-lateral approach II, face-median approach or face-median and face-lateral combined approach. Facial nerve function was evaluated according to the House-Brackmann Facial Nerve Grading System. RESULTS The overall survival rate was 62.5% and 37.5% in the AURS group and conventional group (hazard ratio: 0.59; p < 0.0001), respectively. The disease-free survival rate was 62.5% and 34.3% in the AURS group and conventional group (hazard ratio: 0.43; p = 0.0008), respectively. The local disease control rate in the AURS group (71.4%) was significantly better than that in the conventional group (34.4%) in present study (p < 0.0001). Compared to the conventional group, all the patients undergoing AURS were classified as T4 stage and presented with more lymph node metastasis (71.4%). A total of 20 patients (face-lateral approach I and face-lateral combined approach) were temporarily disconnected from the temporofacial branch of the facial nerve. Fifteen patients exhibited slight paresis, and five patients presented with moderate or severe paresis. The survival rate of zygomatic arch disconnection was 94.6% (54 of 56 patients). CONCLUSION This lateral basicranial surgical approach based on AUSR improves the survival rate and enhances the local control rate while also preserving a good prognosis without damaging the nerve and zygomatic bone. This surgical approach based on AUSR provides a novel and effective surgical treatment to address POSCC with better prognosis, especially for patients without metastatic lymph nodes.

Abstract
BACKGROUND Few models about the personalized prognosis evaluation of buccal mucosa cancer (BMC) patients were reported. We aimed to establish predictive models to forecast the prognosis of BMC patients. METHODS The complete clinicopathological information of BMC patients from the surveillance, epidemiology and end results program was collected and reviewed retrospectively. Two nomograms were established and validated to predict long-term overall survival (OS) and cancer-specific survival (CSS) of BMC patients based on multivariate Cox regression survival analysis. RESULTS 1155 patients were included. 693 and 462 patients were distributed into modeling and validation groups with 6:4 split-ratio via a random split-sample method. Based on the survival analysis, independent prognostic risk factors (variables that can be used to estimate disease recovery and relapse chance) influencing OS and CSS were obtained to establish nomograms. Then, we divided the modeling group into high- and low-risk cohorts. The low-risk cohort had improved OS and CSS compared to the high-risk cohort, which was statistically significant after the Log-rank test (p < 0.05). Furthermore, we used the concordance index (C-index), calibration curve to validate the nomograms, showing high accuracy. The decision curve analyses (DCA) revealed that the nomograms had evident clinical value. CONCLUSIONS We constructed two credible nomogram models, which would give the surgeons reference to provide an individualized assessment of BMC patients.

Abstract
OBJECTIVES To construct predictive models for predicting overall survival (OS) and cancer-specific survival (CSS) of patients with buccal mucosa cancer (BMC). STUDY DESIGN Data of 936 patients with BMC were extracted from the Surveillance, Epidemiology, and End Results (SEER) database from 2004 to 2015. Nomograms were constructed based on multivariate Cox regression analyses, and validated using calibration plots, time-dependent receiver operating characteristic curves, and decision curve analyses. RESULTS Age at diagnosis, marital status, grade, histopathology, SEER stage, tumor size, and surgery were associated with OS, whereas age at diagnosis, grade, histopathology, SEER stage, tumor size, and surgery were associated with CSS (all P < .05). The concordance indexes for OS and CSS were 0.79 and 0.80 in the training cohort, respectively, and those in the validation cohort were 0.78 and 0.80. Time-dependent receiver operating characteristic curves showed great predictability in nomograms. Decision curve analyses demonstrated good clinical value for OS (4%-88%) and CSS (3%-77%) nomograms. Patients were stratified into 3 risk groups, with the worst prognosis in the high-risk subgroup (P < .001). CONCLUSIONS We developed and validated 2 nomograms predicting OS and CSS and established the corresponding risk classification systems in patients with BMC. These models assisted in precise administration of individual therapeutic regimens.

Abstract
Background and Objectives: To investigate clinicopathological characteristics and survival outcomes of patients with buccal cancer in Japan. Materials and Methods: This study was conducted using a database of 1055 patients with oral cancers treated between 2010 and 2017 at 12 institutions in Japan. Ninety-two patients (8.7%) with primary buccal cancer were extracted and clinicopathological characteristics and survival outcomes were compared between patients with buccal cancers and patients with other oral cancers. Results: Ages were significantly higher in the patients with buccal cancer (73 years old vs. 69 years old). Buccal cancer had less advanced cT stage and cN stage than other oral cancers. Overall 5-year survival (OS) was 80.6%, and recurrence-free 5-year survival (RFS) of buccal cancers was 67.8%, and there were no significant differences in survival compared with other oral cancers in terms OS or RFS (5y-OS: 82.5%, 5y-RFS: 74.4%). However, patients with stage IV buccal cancer showed poorer prognosis in terms of OS and RFS compared with the same stage patients with other oral cancer. Advanced T stage was the only factor independently associated with both OS and RFS of patients with buccal cancer in this study. Conclusions: Postoperative radiotherapy or chemoradiotherapy should be considered to improve survival outcome of buccal cancer patients, especially for the patients with advanced primary site disease or a higher cancer stage.

Abstract
OBJECTIVE This study investigated the feasibility and clinical result of radical resection of posterior buccal carcinoma by using the facial nasolabial fold "smile" incision approach. METHODS From August 2016 to March 2017, 23 patients with posterior buccal carcinoma were included in this study and underwent radical surgery. Upon finishing the cervical lymph node dissection, an arc-shaped incision was made at 1 cm lateral to the ipsilateral angulus oris, extending along the nasolabial fold upward to the inferolateral margin of the nasal alar while downward in direct continuity with the neck dissection incision. RESULTS Satisfactory exposure and easy resection of the primary tumor with negative surgical margin were achieved in all 23 patients. After 12-22 months of follow-up (16.5 months on average), all patients recovered favorably, and no local recurrence or distant metastasis was observed. Mouth opening was restored to normal in all cases. The scars were hidden in the nasolabial fold, thus named "smile" incision. CONCLUSIONS For posterior buccal cancer patients, the facial "smile" incision approach can satisfy the need of surgical exposure, facilitate operative performance, and preserve the annular integrity of the lips without affecting the radical tumor ablation, thereby maintaining a favorable mouth opening. With these advantages, the "smile" incision approach is considered worthy of being popularized in clinical application.

Abstract
OBJECTIVE Evaluate current practice patterns in the use of adjuvant radiation for T1-2N1 OCSCC patients and investigate its efficacy in the population-based setting. MATERIALS AND METHODS This study extracted patients who were treated surgically for T1N1 and T2N1 OCSCC without adverse nodal features from the SEER database from 2004 to 2013. Patients with distant metastatic disease, unknown surgery or radiation status, or prior malignancies were excluded. Patients were divided into those who underwent surgical resection with and without adjuvant radiation. Disease-specific survival (DSS) and overall survival (OS) were the primary outcomes measured. RESULTS 746 patients met inclusion criteria and 70% received adjuvant radiation therapy. Treatment with adjuvant radiation therapy was significantly associated with improved 5-year DSS (65% versus 51%; p < 0.001) and OS (54% versus 44%; p = 0.007) for T1N1 tumors. Likewise, improved 5-year DSS (58% versus 38%; p = 0.009) and OS (48% versus 28%; p = 0.004) was shown in T2N1 tumors. Patients with T2N1 tumors wer significantly more likely to receive adjuvant radiation (75% versus 63%; p < 0.001). Those with insurance and high risk primary subsites: buccal, retromolar trigone, and hard palate were more likely to receive adjuvant radiation. The percent utilization of adjuvant radiation remained constant through the study period for T2N1 tumors (72-74%) but significantly decreased for T1N1 (71-55%) (p = 0.047). CONCLUSION Adjuvant radiation therapy is independently associated with a significant survival benefit for patients with both T1N1 and T2N1 OCSCC. However, this study demonstrates that patients with T1N1 cancer are less likely to receive adjuvant radiation and utilization is decreasing.

Abstract
PURPOSE To introduce in-continuity neck dissection (ND) in squamous cell carcinoma of the buccal mucosa (BMSCC) and to determine its impact on the oncologic outcomes of these patients. MATERIALS AND METHODS A retrospective review of patients treated for BMSCC from 2006 through 2016 was performed. Kaplan-Meier analysis and log-rank test were used to evaluate local control, regional control (RC), distant metastasis (DM), and disease-specific survival (DSS) of in-continuity ND versus discontinuous ND in 220 previously untreated patients with BMSCC, followed by a multivariate Cox regression that included all relevant variables. RESULTS Fifty-three patients received discontinuous ND and 167 patients received in-continuity ND. The 2 groups were comparable. Univariate Kaplan-Meier analysis showed that 5-year DSS rates for the discontinuous ND and in-continuity ND groups were 38 and 62% (P = .023), respectively. The 5-year RC rate for the in-continuity ND group (81%) was significantly better (P = .004) than for the discontinuous ND group (54%). At Cox regression analysis, in-continuity ND meaningfully contributed to a higher RC rate and subsequently better DSS. CONCLUSION Compared with discontinuous ND, in-continuity ND predicted favorable oncologic outcomes in patients with BMSCC. In-continuity ND could be a practical approach in the surgical management of BMSCC.

Abstract
PURPOSE Lymph node density(LND) has been shown to be a better prognosticator than conventional nodal classification to predict prognosis for squamous cell carcinoma(SCC) of the oral cavity. However, studies focusing on subsites of oral cancer are meager. The role of LND for buccal SCC was evaluated in this study. METHODS A total of 39 patients with buccal SCC primarily treated surgically with neck dissection were identified. LND was defined as the number of positive nodes over the number of nodal yield. The cut-off of LND was ≤0.07 or >0.07. Patient demographic data and clincopathologic parameters were described. Survival was expressed by Kaplan-Meier method and correlation with survival is analyzed with log-rank test. IBM SPSS Statistics version 22 was used for data computation. RESULTS The median follow-up was 79.0months and median nodes removed was 23 (range 8-93). Positive nodal involvement was found in 19(48.7%) patients. The 5-year and 10-year OS were 67.4% and 42.5% whilst for DSS were 69.2% and 65.5%, respectively. When pT-, pN-, LND-classification and AJCC stage were analyzed for the whole series, only pN- (p=0.006) and LND-classification (p=0.002) were significant factors for OS, while pT-, pN-, LND-classification and AJCC stage were all significant factors for DSS. When only cases with positive nodal spread were considered, the pN-classification (pN1 vs pN2) was not a significant risk factor for either OS (p=0.075, HR 3.10(CI 0.89-10.76)) and DSS (p=0.074, HR 3.58(CI 0.88-14.56)). By contrast, LND-classification (≤0.07 vs >0.07) remained a significant predictor for OS (p=0.03, HR 3.95(CI 1.15-13.63)), but not for the DSS (p=0.112, HR 2.92(CI 0.78-10.99)). CONCLUSION The prognostic value of LND on buccal SCC is supported in this study. The results also suggest that LND is better than the conventional pN-classification to predict OS. Further studies on LND with big sample size for buccal SCC or other subsites of OSCC are worthwhile.

Abstract
OBJECTIVES Although patients with buccal squamous cell carcinoma (SCC) usually show acceptable outcomes, local control and survival rates are generally lower than those observed for tongue SCC. This study was designed to compare the clinical outcomes of Taiwanese patients with these two common oral cavity malignancies. METHODS Patients with first primary buccal or tongue SCC who were included in the Taiwanese Cancer Registry Database between 2004 and 2012 were eligible. The study sample consisted of 16,379 patients (7870 buccal SCC and 8509 tongue SCC) who received surgery with or without adjuvant therapy. The 5-year disease-specific survival (DSS) and overall survival (OS) rates served as the outcome measures. RESULTS Compared with tongue SCC, patients with buccal SCC had a higher prevalence of males (95.7% vs. 86.4%, p<0.0001), pT4 disease (21.4% vs. 12.7%, p<0.0001), and p-Stage IV (30.4% vs. 24.8%, p<0.0001) but a lower frequency of pN2 disease (15.2% vs. 18.5%, p<0.0001). The 5-year DSS and OS rates of buccal SCC patients were slightly higher than those of tongue SCC (78% vs. 77%, p=0.0297; and 71% vs. 69%, p=0.0231, respectively). Multivariate analysis identified tumor site (tongue vs. buccal SCC), sex (male vs. female), age (≥65 vs. <65years), pT classification (T4/T3/T2 vs. T1), and pN classification (N3/N2/N1vs. N0) as independent prognostic factors in the entire study cohort. CONCLUSIONS The survival advantage of buccal SCC over tongue SCC appears significant in large clinical samples, despite a higher prevalence of p-Stage IV disease in the former.

Abstract
BACKGROUND National guidelines support surgical-based treatment and offer nonsurgical therapy as an alternative for advanced-stage oral cavity squamous cell carcinoma (SCC). There are limited data evaluating current utilization of these therapies and their survival outcomes. METHODS A total of 5856 patients were found in the Surveillance, Epidemiology, and End Results (SEER) database from 1988 to 2008 with resectable advanced-stage oral cavity SCC tumors. Outcomes were disease-specific survival (DSS) and overall survival (OS). RESULTS Surgical therapy had significantly improved mean DSS and OS (115 and 71 months, respectively) compared to nonsurgical therapy (63 and 35 months, respectively; p < .001). The use of nonsurgical therapy was significantly associated with the hard palate, and patients who were single, divorced, and black, with T3, T4, and N3 tumors, and the percent utilization has significantly increased from 12% to 20% (p < .05). CONCLUSION Utilization of nonsurgical therapy for advanced-stage oral cavity SCC is increasing and is independently associated with a reduction in survival, as well as patient factors traditionally associated with reduced access to medical care and advanced T and N classifications. © 2016 Wiley Periodicals, Inc.

Abstract
PURPOSE Little is known about whether buccal mucosa elasticity influences the determination of surgical margins for buccal carcinomas. This study investigated whether there is a difference in elasticity of the buccal mucosa in patients with buccal carcinoma compared with controls without the disease. PATIENTS AND METHODS A case-and-control study comprised of patients with buccal carcinoma and controls without the disease was conducted. In each patient, 2 gutta-percha points were attached to the buccal mucosa horizontally and examined twice by lateral cephalometry, once with the mouth closed and once during maximal mouth opening (MMO). Changes in distance between the gutta-percha points were used as a measurement of buccal elasticity. Information on age, alcohol consumption, betel nut chewing, smoking habits, oral submucosa fibrosis (OSF), temporomandibular joint (TMJ) subluxation, and interincisal distance at MMO (IDMMO) was collected. The results were analyzed using independent-sample and paired-sample t tests. RESULTS Ten patients with buccal carcinoma and another 11 patients without buccal carcinoma were enrolled in this study. There was a significant increase in magnification percentage in patients with carcinoma (32.35%; P < .001) during MMO. Magnification of the comparison group during MMO measured 51.55%, also a significant increase (P < .001). Betel nut chewing significantly decreased mucosa elasticity; magnification was 29.20% (P = .013). Magnification was significantly higher in patients with TMJ subluxation (54.50%; P = .041) than in the controls. Age, alcohol consumption, smoking, OSF, and IDMMO did not affect buccal mucosa elasticity. CONCLUSIONS Buccal mucosa elasticity increased considerably at MMO in patients with buccal carcinoma. This elasticity should be taken into account when calculating adequate surgical margins for transoral resection of buccal carcinoma.
