Pretreatment Tumor Volume and Tumor Sphericity as Prognostic Factors in Patients with Oral Cavity Squamous Cell Carcinoma: A Prospective Clinical Study in 95 Patients. J Pers Med 2023; 13:1601. [PMID: 38003916 PMCID: PMC10672547 DOI: 10.3390/jpm13111601] [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: 10/07/2023] [Revised: 11/10/2023] [Accepted: 11/11/2023] [Indexed: 11/26/2023] Open
Abstract
The prognostic impact of tumor volume and tumor sphericity was analyzed in 95 patients affected by oral cancer. The pre-operative computed tomography (CT) scans were used to segment the tumor mass with threshold tools, obtaining the corresponding volume and sphericity. Events of recurrence and tumor-related death were detected for each patient. The mean follow-up time was 31 months. A p-value of 0.05 was adopted. Mean tumor volume resulted higher in patients with recurrence or tumor-related death at the Student's t-test (respectively, 19.8 cm3 vs. 11.1 cm3, p = 0.03; 23.3 cm3 vs. 11.7 cm3, p = 0.02). Mean tumor sphericity was higher in disease-free patients (0.65 vs. 0.59, p = 0.04). Recurrence-free survival and disease-specific survival were greater for patients with a tumor volume inferior to the cut-off values of 21.1 cm3 (72 vs. 21 months, p < 0.01) and 22.4 cm3 (85 vs. 32 months, p < 0.01). Recurrence-free survival and disease-specific survival were higher for patients with a tumor sphericity superior to the cut-off value of 0.57 (respectively, 49 vs. 33 months, p < 0.01; 56 vs. 51 months, p = 0.01). To conclude, tumor volume and sphericity, three-dimensional parameters, could add useful information for better stratification of prognosis in oral cancer.

Am J Otolaryngol 2023; 44:103740.

Abstract
PURPOSE New prognostic factors in oral squamous cell carcinoma (OSCC) (tumor-, host-, and environment-related) have been introduced recently to complete those traditionally considered. Among them, tumor volume (TV) could be the most interesting and applicable in clinical practice, considering the routine use of computed tomography in tumor staging. In this retrospective study we aimed to investigate whether a correlation exists among these new prognostic factors and survival outcomes. METERIALS AND METHODS We collected data about 140 patients affected by OSCC who underwent primary surgery. Prognostic factors were collected and Overall Survival (OS), Disease Specific Survival (DSS) and Disease Free Survival (DFS) were estimated using Kaplan-Meier method; the Log-Rank test (Mantel-Cox) and Cox regression models were applied to investigate predictors of survival. RESULTS The 5-year OS, DSS and DFS were 73.6 %, 89.2 % and 75.2 % respectively. Nodal metastasis (pN+), relapse and American Society of Anesthesiologists ASA-II were found independent prognostic factors for OS, and significantly associated to worst DSS (p < 0.001). TV significantly correlated with higher relapse occurrence (p = 0.03). CONCLUSIONS In our experience, lymph-node status, ASA classification and relapse significantly influenced DSS on univariate analysis. TV could represent an interesting additional parameter, since it significantly influenced DFS. However, prospective studies with standardized TV measurements and a greater number of patients are needed to validate this result.

Abstract
Oral squamous cell carcinoma (OSCC) is the eighth most common type of cancer in the world. Knowledge of prognostic factors of survival in OSCC is key. Several clinical and pathological prognostic factors have been investigated to develop a prognostic model of survival for patients with oral cancer. The present study focused on the association between pathological tumor volume (PTV) and overall survival time in patients with OSCC, regardless of cervical nodal status. The present study was a prospective study and covered 65 consecutive patients who received surgical treatment for oral cancer. The PTV was calculated according to dimensions of the postoperative specimen. Other pathological parameters as perineural and perivascular tumor spreading and extra-nodular propagation were also determined. The data were analyzed using the IBM SPSS 25.0 software. Cox PH regression model was built to analyze association between the PTV and survival time. Survival time was defined as the period from surgery to a target event or last contact. The results of the present study showed that PTV >4.24 cm3 was significantly associated with shorter overall survival time in patients with OSCC. The PTV value was higher in patients with metastasis and in patients with higher pathological tumor and node stage. In conclusion, PTV was an important pathological prognostic factor for survival in patients with OSCC.

Abstract
(1) To determine tumor volume by clinical measurement, imaging and histopathological examination in patients with squamous carcinoma of buccal mucosa. (2) To correlate tumor volume with lymph-node metastasis and loco-regional control. Retrospective Observational Study. Rural tertiary care hospital. 75 Patients undergoing surgery for T2 (68%) and T3 (32%) Oral squamous carcinomas were included in this observational study. Tumor volume-a product of maximum length, breadth and thickness, was determined clinically and by imaging. Tumor volume on histopathology was documented and correlated with lymph-node metastasis. After 13 months minimum follow-up, tumor volume was correlated with loco-regional control. Recurrences were analysed with regard to tumor volume, depth of invasion, lymph-node metastasis and resection margins. Average tumor volume was 7.1 cm3among T2 and 14.4 cm3among T3. 25% of T2 tumors had metastatic lymph-nodes compared to 33.3% in T3. There was positive correlation between tumor volume and lymph-node metastasis. Lymph-node metastasis was absent when tumor volume was < 8 cm3. There were 4 local and 2 regional recurrences in this study. Average histopathological tumor volume among patients who had local recurrence was 12.95 cm3. Regional recurrences occurred in tumors staged N2b and N3b on histopathology. Average depth of invasion in patients with recurrence was 10.33 mm.. Tumor volume represents actual tumor load and correlates with lymph node metastasis and prognosis in oral cancers. Depth of invasion and tumor thickness influence staging and prognosis. Large volume tumors have poor oncological outcome.

Abstract
Oral squamous cell carcinoma (OSCC) forms the majority of the entire cancerous tumors which occur in the mouth. Current treatment advances, such as surgical resection, chemotherapy, and radiotherapy, have significantly helped reduce OSCC. However, the overall patient survival rate remains relatively low. MiRNAs, a non-coding RNA group, are essential for multiple biological functions, which are essential for the progression of cancer, including survival of the cell, migration, multiplication, differentiation, and apoptosis. The study aimed to explore the existing association between miR-487a-3p and PPM1A and elucidating their role in modulation of proliferation in OSCC cell lines. In this study, we used CAL-27 and TCA-8113 OSCC cell lines and human samples to validate our results. The manifestation of miR-487a-3p and PPM1A was checked using quantitative real-time PCR. The miR-487a-3p and PPM1A binding was investigated through western blot assay and dual-luciferase reporter gene. Functional experiments, including colony formation, CCK-8, and transwell experimentations, were undertaken to validate cells' growth and invasion activities. According to the results, the expression of miR-487a-3p is regulated in the OSCC cell lines compared to normal cells. Moreover, the mimicking of miR-487a-3p significantly reduces the OSCC cell growth and invasion, and PPM1A overexpression exerts oncogenic effects and hinders the anti-oncogenic effects of miR-487a-3p. In conclusion, the study demonstrated that miR-487a-3p might act as a tumor suppressor by inhibiting the growth and invasion of OSCC via regulating PPM1A expression.

Abstract
Previous studies have reported that as the main extract of areca nut, arecoline (ARE) causes DNA damage and in turn contributes to the carcinogenesis of oral epithelial cells. It has been reported that ARE can inhibit the expression of miR-886-3p. In the current study, we aimed to explore the expression and biological functions of miR-886-3p in oral squamous cell carcinoma (OSCC). Herein, we demonstrated that in OSCC cells treated with ARE, the expression level of miR-886-3p was negatively correlated with the concentration of ARE. Compared with adjacent tissue, the expression level of miR-886-3p in OSCC tissue was remarkably downregulated. Transfection of miR-886-3p mimics markedly decreased viability, migration and invasion of OSCC cells. These experimental data implied that miR-886-3p suppression mediated by ARE took part in the proliferation and metastasis of OSCC. This study can help elucidate the mechanism by which areca nut chewing contributes to the malignant transformation of oral epithelial cells.

Abstract
OBJECTIVE The aim of this study was to evaluate the efficacy of preoperative intraoral ultrasonography (US) in the assessment of tumor depth of invasion (DOI) in oral squamous cell carcinoma (OSCC). STUDY DESIGN Records of 32 patients with biopsy-proven OSCC who underwent preoperative intraoral US were retrospectively reviewed. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy as indicated by receiver operating characteristic (ROC) analysis were measured for US in the assessment of the infiltration of the tumor beyond the lamina propria into the submucosa. The correlations between US and histologic DOI, and between US DOI and US diameter of the lesion, were assessed. RESULTS US sensitivity, specificity, PPV, and NPV in the assessment of the infiltration of the tumor beyond the lamina propria into the submucosa were 93.1%, 100%, 100%, and 60%, respectively. The area under the ROC curve was 0.96. A significant correlation was found between the measurements of US DOI and histological DOI (r = 0.907). A moderate correlation was found between US DOI and US diameter (r = 0.591). CONCLUSIONS Intraoral US has potential in preoperatively determining tumor DOI and may provide additional guidance for optimal planning of therapy for OSCC patients .

Abstract
BACKGROUND To demonstrate that post-therapy pathological tumor volume (ypTV) should be considered as an independent prognostic factor in advanced gastric cancer (GC) patients who underwent neoadjuvant chemotherapy (NAC) and gastrectomy. METHODS A total of 253 GC patients who received gastrectomy between January 2010 and December 2016 in our hospital were enrolled in this study. Clinicopathologic factors were evaluated using univariable and multivariable analysis. ypTV was calculated using π* (tumor diameter/2)2 *tumor invasion depth (cm3). RESULTS Cut-point survival analysis demonstrated that the appropriate cut-offs for ypTV were 3, 6, 10, and 19 (cm3). Patients with tumor volumes of 0-3.0, 3.1-6.0, 6.1-10.0, 10.1-19.0, ≥19.1 cm3 were defined as ypTV1, 2, 3, 4a and 4b. Using multivariable analysis, the tumor volume (ypTV stage, P < 0.05), ypN stage (P < 0.05), response to NAC (P < 0.05), vascular invasion (P < 0.05) and ypTvNM staging (P < 0.05) were independent prognostic factors. Kaplan-Meier analysis demonstrated that the 8th AJCC/UICC ypTNM staging was not a significant predictor for survival (P > 0.05); however, our newly defined ypTvNM staging was a significant predictor for survival (P < 0.05). CONCLUSIONS ypTV should be considered as an independent prognostic factor for GC patients after NAC. ypTvNM staging should be recommended to improve the accuracy of prognostic prediction for GC patients who received NAC plus gastrectomy.

Abstract
PURPOSE This study was designed as a retrospective observational study, focusing on the correlation between the preoperative CT-scan tumor volume, tumor sphericity, and the disease-related prognosis. METHODS A total of 30 consecutive patients, affected by primary oral cancer, were retrospectively identified from our oral cancer database. The preoperative images (DICOM data) for the study population were uploaded into a modular software package designed to convert patients' medical images into 3D digital models. Multislice interpolation and threshold segmentation tools were used to segment the tumor mass. This was then converted into a 3D mesh and exported in STL format, in order to calculate the corresponding volume. We applied the concept of sphericity - a measurement of how closely the shape of an object approaches that of a mathematically perfect sphere - to the segmented tumor mass. RESULTS Mean tumor volume was larger in patients with tumor recurrence and/or who had died than in patients who were disease free/alive. Tumor sphericity was influential on clinical outcomes. It appeared to be lower in patients who had tumor recurrence and/or who had died (0.54 ± 0.09 and 0.53 ± 0.05) than in patients who were disease free/alive (0.65 ± 0.07). This difference was statistically significant (p < 0.05). Cumulative recurrence-free survival was 86.2% for patients with a tumor volume lower than the cut-off value. Otherwise, it was 0% for those with a tumor volume higher than the cut-off value (p < 0.01; log rank test). Cumulative recurrence-free survival was 86.3% for patients with a higher sphericity index, compared with 13.6% for those with a lower sphericity index. CONCLUSION The prognostic model, based on a tridimensional, CT-based characterization of the tumor size, which includes both tumor volume and tumor sphericity, uses readily available information and could be considered when formulating prognoses for patients with oral cancer.

Abstract
OBJECTIVES/HYPOTHESIS Inverted papillomas (IPs) are benign tumors of the sinonasal tract with a malignant transformation potential. Predicting the transformation propensity of IPs and corresponding risk factors has long been a challenge. In this study, we aimed to use radiographic findings on magnetic resonance imaging (MRI) and computed tomography (CT) to help differentiate IP from IP-transformed squamous cell carcinomas (IP-SCC). STUDY DESIGN Retrospective cohort study. METHODS A retrospective analysis was performed at two institutions comparing IP (n = 76) and IP-SCC (n = 66) tumors, evaluating preoperative radiographic imaging with corresponding surgical pathology reports. The presence of a convoluted cerebriform pattern (CCP) using postcontrast T1-weighted and T2-weighted MRI was evaluated. Using MRI diffusion-weighted imaging (DWI), we calculated the apparent diffusion coefficient (ADC) value of each tumor. We also determined the tumor origin, attachment sites, and presence of bony erosion using CT imaging. RESULTS Benign IPs had a higher prevalence of CCP on MRI compared to IP-transformed SCC (P = .0001. The mean value ADC of malignant IP-SCC (ADCb0,1000 = 1.12 × 10-3 mm2 /s) was significantly lower than that of benign IPs (ADCb0,1000 = 1.49 × 10-3 mm2 /s, P = .002). IP-SCC tumors were more likely to be have orbital wall attachment (P = .002) and bony erosion (P < .0001) compared to IPs. CONCLUSIONS Evaluation of CCP and DWI with ADC values on MRI are promising qualitative and quantitative methods to help differentiate benign IP tumors from their transformed malignant counterparts. Malignant IP-SCCs are associated with a loss of CCP and lower ADC values. Findings of orbital wall involvement and bony erosion on CT may also help determine presence of malignancy.

Abstract
Background The ability of health care professionals to perform oral cancer examination depends partly on their knowledge of the disease and its risk factors. This study aimed to assess and compare the knowledge of final year students, interns and faculty members regarding oral cancer and its risk factors. Material and Methods A 35-item questionnaire about knowledge of oral cancer and its risk factors was distributed among participants from Jazan University’s Dental School. A minimum score of 18 was the cut-off point for an acceptable total score of oral cancer knowledge [OCTS]. Descriptive statistics described the relations between demographics variables and knowledge levels of participants. The differences between OCTS, diagnostic-clinical examination knowledge [DCK] and supportive knowledge [SK] and sex and occupation were analyzed using independent t-test and ANOVAs respectively. Results A total of 72 students, 68 interns and 88 faculty members completed the questionnaires (N = 228); with an average age of 23.8 ± 0.9 years, 25.1 ± 1.5 years and 40.6 ± 9.1 years with 55.1% males. OCTS was 20.2 ± 3.6 out of 35. No significant difference between OCTS and participants’ sex was found (t (203) = 1.342, p = .181, 95% CI for difference -.302 ــ 1.589). No significant differences in OCTS between students, interns and faculty members (F (2, 225) = 2.116, p = .123). A significant difference in SK between final year students, interns, and faculty members was founded (F (2, 194) = 5.62, p = .004). Conclusions Knowledge of oral cancer and its risk factors among Jazan Dental School’s final year students, interns and faculty members is acceptable. However, due to the high rate of oral cancer in Jazan, emphasizing knowledge of oral cancer and its risk factors in the curriculum of Jazan Dental School is required. Key words:Oral cancer, risk factors, knowledge, dental education, curriculum, dental students, dentists.

Abstract
The present study examined whether the pathological tumor volume (PTV) was correlated with the survival outcomes in patients with oral squamous cell carcinoma (SCC) and clinical lymph node metastasis. Forty-seven patients who underwent radical surgery without preoperative treatment were enrolled. The PTV of the primary tumor, which was surgically resected without preoperative treatment, was calculated based on the diameters in three dimensions. A survival analysis was performed using a Cox proportional hazards model. A PTV of ≥18 cm3 was significantly correlated with shorter overall survival (P<0.01) and local recurrence-free survival (P<0.01) in a univariate analysis. A multivariate analysis with adjustment for the pathological stage (stage I–II/III–IV), primary site (tongue/others) and positive surgical margin and/or extracapsular extension (absent/present) showed that a PTV of ≥18 cm3 was significantly correlated with shorter overall survival (P<0.01) and local recurrence-free survival (P<0.01). The present findings suggested that PTV in oral SCC provides a prognostic parameter that may predict shorter or longer overall and local recurrence-free survival.

Abstract
OBJECTIVES 3D virtual surgical planning (VSP) and guided surgery has been proven to be an effective tool for resection and reconstruction of the mandible. Currently, most widely used 3D VSP approaches to mandibular resection do not include detailed tumour information in the VSP. This manuscript presents a strategy where the aim was to incorporate tumour visualisation into the 3D virtual plan. Three-dimensional VSP of the mandibular resections was based on the fusion of CT and MRI data which was subsequently applied in clinical practice. METHODS All patients diagnosed with oral squamous cell carcinoma between 2014 and 2017 at the University Medical Centre Groningen were included. The tumour was delineated on the MRI data, after which this dataset was fused with the CT bone data in order to construct a 3D bone and tumour model for virtual resection planning. Guided resections were performed and post-operative evaluation quantified the accuracy of the resection. The histopathological findings and patient and tumour characteristics were compared to those of a historical cohort (2009-2014) of conventional mandibular continuity resections. RESULTS Twenty-four patients were included in the cohort. The average deviation from planned resection was found to be 2.2 mm. Histopathologic analysis confirmed all resection planes (bone) were tumour free, compared to 96.4% in the historic cohort. CONCLUSION MRI-CT base tumour visualisation and 3D resection planning is a safe and accurate method for oncologic resection of the mandible. It is an improvement on the current methods reported for 3D resection planning based solely on CT data.

Abstract
The aim of our study was to investigate the effects of miR-133a-3p on human oral squamous cell carcinoma (OSCC) cells by regulating gene COL1A1. OSCC tissues, adjacent tongue epithelial tissues, the immortalized oral epithelial cell line HIOEC, and OSCC cell lines (CAL-27, TCA-8113, SCC-4, SCC-9, and SCC-15) were used in this research. Quantitative real-time PCR (RT-qPCR) was employed to determine the expression of miR-133a-3p and COL1A1. Dual luciferase reporter gene assay and Western blot were applied to verify the binding relationship between miR-133a-3p and COL1A1. Functional assays were also conducted in this study, including CCK-8 assay, colony formation assay, flow cytometry analysis as well as Transwell assay. MiR-133a-3p was found low-expressed both in OSCC tissues and cells lines compared with normal tissues and cell line, respectively, whereas COL1A1 was just the opposite. The over-expression of miR-133a-3p or the down-regulation of COL1A1 suppressed the proliferation, invasion, and mitosis of OSCC cells, whereas simultaneous down-regulation of miR-133a-3p and up-regulation of COL1A1 led to no significant alteration of cell activities. MiR-133a-3p could inhibit the proliferation and migration of OSCC cells through directly targeting COL1A1 and reducing its expression. J. Cell.

Abstract
PURPOSE OF REVIEW Management of advanced head and neck cancer (HNC) is characterized by high mortality. Furthermore, the treatment involves significant burden to patients and high costs to healthcare systems. Recognizing the risks of early death in patients with a high probability of noncurable disease is important for each individual treatment decision-making. It is thus critical to consider the benefits and side-effects of the planned treatment in relation to the expected survival and to discuss these factors with the patient. However, only few studies have documented early death in HNC patients, that is, during the first posttreatment 6 months. We performed a systematic literature review to find the incidence of this phenomenon and to outline the probable cause. RECENT FINDINGS Early mortality in patients with HNC can be explained either by direct effect of malignant disease, may be related to comorbidities, or secondary to the treatment. These factors act together resulting in expected or unexpected early death. SUMMARY The present review provides information on the mechanisms leading to early phase mortality (<6 months) after management of HNC. It also reports the incidence of this phenomenon among Finnish and Swedish patient populations.

Abstract
BACKGROUND The purpose of this study was to identify clinicopathological and immunohistochemical factors predicting delayed lymph node metastases and survival in early oral squamous cell carcinoma (OSCC). METHODS The study included 85 consecutive patients with clinically T1 to T2N0 OSCC who were primarily surgically treated between 2000 and 2004. RESULTS There were 68 men and 17 women (median age, 61 years; range, 34-82 years). Of all the patients, 25 (29.4%) developed delayed lymph node metastases within 3 to 42 months after treatment of the primary tumor. Multivariate logistic regression analysis identified poorly differentiated tumors, low laminin, and high fibronectin expression as prognosticators of delayed lymph node metastases. Cox's proportional hazards regression analysis demonstrated that moderately differentiated tumors and delayed lymph node metastases had predictive value regarding survival. CONCLUSION Large prospective investigations with reproducibility and the clinical translatability of immunohistochemical methods are needed in order to provide new and effective therapeutic strategies in the future. © 2016 Wiley Periodicals, Inc.

Abstract
Objective: To assess the effects of tumor size, proximity to midline and invasion depth of oral cancer of the tongue (TC) on neck metastasis and recurrence. Methods: In this retrospective observational study, was conducted through a chart review of the 11 male and 9 female patients who underwent surgeries with the diagnosis of tongue squamous cell carcinoma and at least one side neck dissection. We wanted to assess effects of tumor size, proximity to midline, and invasion depth of TC, according to the surgical specimens and pre-operative magnetic resonance imaging, on neck metastasis and recurrence between 2007 and 2014. The study was conducted in a training hospital-based otorhinolaryngology clinic. Statistical analyses were performed to determine possible relationship between such tumor features and tumor recurrence and neck metastasis. Results: Statistically significant relationship were detected between recurrence and the proximity of tumor to midline (p=0.031) and between invasion depth and neck metastasis (p=0.017). No relationship was found between tumor size and recurrence and neck metastasis (p=0.721 and p=0.827, respectively). Conclusions: Parameters like invasion depth and tumor proximity to midline might provide useful information about prognosis and may help to determine a treatment schedule in patients suffering fdrom cancer of the tongue. The present TNM classification might not be sufficient to provide enough information to determine prognosis and staging adequately in these patients.

Abstract
OBJECTIVES Oral squamous cell carcinomas, and tongue malignancies in particular, are among the most common tumors of the oral cavity. Classification for therapeutic and prognostic purposes is routinely made using the tumor, node, metastasis (TNM) system; however, current definitions do not include tumor thickness. We therefore aimed to identify variables associated with survival, and to evaluate the correlation between tumor thickness and the occurrence of lymph node metastasis. PATIENTS AND METHODS All patients undergoing radical tumor resection for squamous cell carcinomas of the tongue between 2000 and 2012 were included. Specimens were analyzed histopathologically and co-variables were interpreted. Follow-up was performed clinically and radiologically for at least 3years according to current guidelines. RESULTS We included 492 patients who had a median follow-up of 70months. Variables associated with survival (p<0.05) were age, tumor stage, N stage, UICC (Union for International Cancer Control) stage, tumor grade, and recurrence. In the receiver operating characteristic curve and Youden-Index analyses, the optimal tumor thickness cut-off was 8mm to detect significant differences in overall survival. CONCLUSION We highlight the importance of tumor thickness as a predictive variable in tongue cancer. Specifically, a cut-off point of 8mm allowed for a more accurate and statistically precise prediction of lymph node metastasis. These findings could supplement the current classification of tongue cancers and form the basis for treatment.
