pStage IVB oral cavity squamous cell carcinoma (OCSCC) is defined as either pT4b or pN3 disease. We sought to devise an improved prognostic stratification of this patient group.Between December 2003 and January 2018, we retrospectively reviewed the clinical records of 1331 consecutive patients with OCSCC who received tumor excision and neck dissection. The number of patients with pT4a/pT4b, pT1N3b/pT2N3b/pT3N3b/pT4N3b, and pStage IVA/IVB was 370/83, 3/49/42/142, and 332/295, respectively.The 5-year rates of disease-free survival (DFS) and disease-specific survival (DSS) for patients with pT4a/pT4b disease were 64%/63% (p = 0.973) and 72%/69% (p = 0.672), respectively. The 5-year DFS and DSS rates for patients with pT1N3b/pT2N3b/pT3N3b/pT4N3b disease were 67%/65%/40%/42% (p 0.001; pT1-2N3b versus pT3-4N3b, p = 0.002) and 100%/68%/45%/49% (p 0.001; pT1-2N3b versus pT3-4N3b, p = 0.002), respectively. We devised a new definition for pStage IV by considering patients with pT4bN0-2 and pT1-2N3b diseases as pStage-IVA. The number of patients with pStage IVA/IVB (pT3-4N3b) was 443/184. The 5-year rates of AJCC pStage IVA/IVB and the newly proposed pStage IVA/IVB (pT3-4N3b) were as follows: DFS, 74%/52% and 72%/42%; DSS, 83%/58% and 81%/47%; respectively, all p value 0.001.The clinical outcomes of pT4b and pT4a OCSCC are similar. However, patients with pT3-4N3b disease have a less favorable 5-year prognosis compared with cases with pT1-2N3b. In light of the unfavorable outcomes, pT3-4N3b disease should continue to be classified as pStage IVB. Conversely, pT4bN0-2 and pT1-2N3b diseases portend a less adverse prognosis and should therefore be downstaged to pStage IVA.

Objectives The postoperative outcomes of patients with oral cavity squamous cell carcinoma (OCSCC) vary greatly. To improve risk stratification, we sought to identify genetic biosignatures by whole-exome sequencing (WES). Materials and Methods We retrieved patients with OCSCC patients with paired freshly frozen malignant and non-malignant tissue specimens and performed WES by Illumina HiSeq4000 platform. We further applied a tree-based method to analyze copy number variations and obtain signature classification and driver-gene identification. We further confirmed the prognostic impact of the WES biosignature in an external independent validation set. Results We examined 168 paired samples from patients with surgically treated OCSCC. Similar to the literature, the most commonly mutated genes were TP53 (66%), FAT1 (32%), and NOTCH1 (24%). The signatures 13 (APOBEC Cytidine deaminase [C > G]), 1 (spontaneous deamination of 5-methylcytosine), and 7 (UV exposure) showed the highest concordance rates. Using the MutSigCV, MuSiC, 20/20+, OncodriveFML, e-Driver, OncodriveCLUST, and tree-based methods, we identified a nine-gene OCSCC panel (RYR1, HLA-B, TSHZ2, PCDH17, DNAH17, GRID1, SBNO2, KSR2, and GCN1L1) predicting survival outcomes in our sample. We used the TCGA database to validate the prognostic value of the panel independently. Furthermore, gene-gene covariance analysis confirmed the coexistence of several gene alterations. Conclusion We identified and independently validated a WES biosignature that predicts outcomes in surgically treated OCSCC in Taiwan, a betel-quid-chewing-prevent area. We proposed that the panel might help clinical trial designation for adjuvant therapy based on the risk stratification from the novel gene panel and identify targets for liquid biopsy monitoring during surveillance.

Patients were divided into two subgroups based on their EBV DNA titers (high versus low). In the high EBV DNA titer group, a lower homogeneity of distant metastatic lesions and higher TLG values of distant metastatic lesions were independent risk factors for OS (P = 0.033 and P 0.001, respectively). In the low EBV DNA titer group, a reduced uniformity of distant metastatic lesions and a higher SUVmax of distant metastatic lesions were unfavorable risk factors for OS (P = 0.004 and P = 0.005, respectively). Based on these results, we devised two prognostic scoring systems for the prediction of 2-year OS in each EBV DNA titer group.Some of the PET-derived texture parameters are independent predictors of outcomes in patients with metastatic NPC and provide complementary information to EBV DNA titers.

Objectives Human papillomavirus-negative oropharyngeal squamous cell carcinoma (OPSCC) has unfavorable survival outcomes. Two outcomes have been identified based on smoking history and tumor stage. We investigate the prognostic role of pre-treatment positron emission tomography (PET) in high-risk OPSCC. Materials and Methods We enrolled 147 M0 OPSCC patients with p16-negative staining and a history of heavy smoking (>10 pack-years) or T4 disease. All patients completed primary chemoradiotherapy, and 42% maximum standard uptake values (SUVmax) were used as the threshold for primary tumor. Patients were classified into training and validation cohorts with a ratio of 1:1.5 according to the PET date. Heterogeneity and irregularity indices were obtained. PET parameters with significant impact on progression-free survival (PFS) in receiver operating characteristic curves and univariate Cox models were identified and included in recursive partitioning analysis (RPA) for constructing a prognostic model. The RPA-based prognostic model was further tested in the validation cohort using multivariate Cox models. Results Fifty-eight and 89 patients were in the training and validation groups, respectively. Heterogeneity parameter, SUV-entropy (derived from histogram analysis), and irregularity index, and asphericity were significantly associated with PFS. The RPA model revealed that patients with both high SUV-entropy and high asphericity experienced the worst PFS. Results were confirmed in the validation group. The overall concordance index for PFS of the model was 0.75, which was higher than the clinical stages, performance status, SUVmax, and metabolic tumor volume of PET. Conclusions PET prognostic model provided useful prediction of PFS for patients with high-risk OPSCC.

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.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.Compared with tongue SCC, patients with buccal SCC had a higher prevalence of males (95.7% vs. 86.4%, p0.0001), pT4 disease (21.4% vs. 12.7%, p0.0001), and p-Stage IV (30.4% vs. 24.8%, p0.0001) but a lower frequency of pN2 disease (15.2% vs. 18.5%, p0.0001). 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.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.

Purpose The aim of the present study was to evaluate whether texture features extracted from 18F-FDG PET/CT images may provide additional prognostic information in patients with metastatic nasopharyngeal carcinoma (NPC). Materials and Method We retrospectively examined 52 patients with metastatic NPC who underwent assessment of EBV DNA titers and pretreatment 18F-FDG PET/CT imaging. All participants were followed up for at least two years. The following 18F-FDG PET parameters were analyzed: standardized uptake value (SUV), metabolic tumor volume (MTV), total lesion glycolysis (TLG), and texture parameters. Independent predictors of outcomes were identified using receiver operating characteristic curve analysis and multivariate Cox proportional hazards models.

According to the AJCC 2017 Staging Manual, oral cavity squamous cell carcinoma (OCSCC) with pN2 disease (based on the AJCC 2010 criteria) and extra-nodal extension (ENE) should be classified as pN3b. We performed a detailed outcome analyses in this patient subgroup.We retrospectively reviewed the clinical records of consecutive OCSCC patients who underwent radical surgery between 1996 and 2017. Patients with pN3b disease (n = 365) were divided into a pN+ ≥8/ENE ≥5 subgroup (defined by the presence of pN+ ≥8 nodes or ENE ≥5 nodes, n = 77) and a pN+ ≤7/ENE ≤4 subgroup (defined by the presence of pN+ ≤7 nodes and ENE ≤4 nodes, n = 288). Patients with pN0/pN1/pN2 (n = 1192/179/197) disease were included for comparison purposes.Patients in the pN+ ≥8/ENE ≥5 subgroup had less favorable 5-year outcomes than those in the pN+ ≤7/ENE ≤4/pN2/pN1/pN0 groups (local control, 64%/79%/86%/83%/88%, p 0.001; neck control, 55%/75%/80%/86%/93%, p 0.001; distant metastases, 67%/28%/20%/12%/3%, p 0.001; disease-free survival, 21%/51%/64%/72%/82%, p 0.001; disease-specific survival, 25%/55%/71%/82%/92%, p 0.001; overall survival, 19%/40%/54%/64%/82%, p 0.001; respectively). Among patients with pN3b disease, multivariable analysis identified the pN+ ≥8/ENE ≥5 subgroup, lower neck (level IV/V) metastases, and depth of invasion ≥25 mm as independent adverse prognostic factors for 5-year distant metastases and survival rates.Patients in the pN+ ≥8/ENE ≥5 subgroup have an unfavorable prognosis and their classification as pN3b is advisable. In contrast, patients in the pN+ ≤7/ENE ≤4 subgroup should be classified as pN3a.

Independent predictors of outcomes were identified using receiver operating characteristic curve analysis and multivariate Cox proportional hazards models.Results: On multivariate analysis, EBV DNA titers > 3500 copies/mL and TLG of metastatic lesions > 138 mL were identified as independent predictors of overall survival (OS) (P = 0.036 and P = 0.047, respectively). Patients were divided into two subgroups based on their EBV DNA titers (high versus low). In the high EBV DNA titer group, a lower homogeneity of distant metastatic lesions and higher TLG values of distant metastatic lesions were independent risk factors for OS (P = 0.033 and P < 0.001, respectively). In the low EBV DNA titer group, a reduced uniformity of distant metastatic lesions and a higher SUVmax of distant metastatic lesions were unfavorable risk factors for OS (P = 0.004 and P = 0.005, respectively). Based on these results, we devised two prognostic scoring systems for the prediction of 2-year OS in each EBV DNA titer group.Conclusion: Some of the PET-derived texture parameters are independent predictors of outcomes in patients with metastatic NPC and provide complementary information to EBV DNA titers.
