JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2024; 125:101673. [PMID: 37923135 DOI: 10.1016/j.jormas.2023.101673] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 10/25/2023] [Accepted: 10/28/2023] [Indexed: 11/07/2023]
Abstract
The purpose of this study was to evaluate the utility of ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (FPCT) parameters for detecting recurrent disease and the outcomes of salvage surgery in patients with locally advanced oral tongue squamous cell carcinoma (TSCC) after multimodal treatment. In total, 69 patients with locally advanced TSCC were treated with multimodal therapy. All patients underwent whole-body FPCT scans 4-10 months after the initial surgery. The analysis included FPCT parameters, such as maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis (TLG). Histological examination was used as the reference standard. Patients with recurrent TSCC underwent salvage surgery or surgery plus systemic treatment. This study included 69 patients: 36 in the recurrent TSCC group and 33 in the non-recurrent TSCC group. The SUVmax, MTV, and TLG in the recurrent TSCC group were 11.3 ± 3.6, 28.3 ± 15.6 cm3, and 113.2 ± 46.8 g, respectively; these values were 5.9 ± 3.6, 5.1 ± 2.2 cm3, and 13.4 ± 4.8 g, in the non-recurrent TSCC group respectively. The two groups had significant differences in terms of SUVmax, MTV, and TLG. In the recurrent TSCC group, 91.6 % of patients presented with local, locoregional, and regional disease and underwent salvage surgery plus systemic therapy, whereas 8.4 % had locoregional recurrence with distant metastases alone and underwent surgery plus systemic therapy. The patients were followed up for 12-60 months; 19 and 20 patients in the recurrent and non-recurrent TSCC groups showed no evidence of disease, whereas 11 and 8 were alive with the disease. Local recurrence or distant metastases led to the deaths of six patients in the recurrent TSCC group and five in the non-recurrent TSCC group. No significant differences in survival were observed between the two groups. FPCT parameters can detect the recurrence of locally advanced TSCC after multimodal treatment. Early salvage surgery can improve the treatment outcomes for recurrent TSCC.

Abstract
Introduction: Patients with OSCC in India (oral squamous cell carcinoma) presents at a later stage with approximately 28% presenting at stage III and 64% at stage IV disease. In this retrospective study we have reviewed the treatment modalities rendered and outcomes associated for the management of locally advanced oral squamous cell carcinoma in our Institute. We evaluated the survival data and the factors effecting survival. Methods: Kaplan Meir method was used to evaluate OS and DFS rate and log rank test was used to compare the survival amongst groups. Cox regression analysis (univariate and multivariate) was used to evaluate the hazard ratio to find out the possible factors influencing risk of death and disease. Results: The median OS and DFS in our study were 32 and 24 months respectively. On a subset analysis of only T4b patients who underwent either upfront surgery or induction chemotherapy followed by surgery there was no significant difference in OS and DFS. All patients with TURD had partial response after induction chemotherapy and were subjected to surgical resection followed by adjuvant therapy. Conclusion: Extracapsular spread, bone involvement, skin infiltration, treatments, surgical margins and Lymph node size are the prime predictors of survival.Upfront surgery remains the standard of care for resectable LAOSCC. Induction chemotherapy might improve the resectability in technically unresectable OSCC. There is no difference in survival between concurrent chemoradiation, sequential chemoradiation and radical radiotherapy in the management of unresectable disease.

Abstract
Management of locally advanced OSCC include primary surgery followed by adjuvant radiotherapy or chemo radiation, concurrent chemo radiation, induction chemotherapy followed by surgery or non surgical methods. In resectable disease the role of induction chemotherapy is questionable and surgery remains the first choice. In this study we aimed at evaluating the survival and factors effecting survival in locally advanced oral cancer. retrospective review of patient records was made. Kaplan Meir method was used to evaluate OS and DFS rate and log rank test was used to compare the survival amongst groups. Cox regression analysis (univariate and multivariate) was used to evaluate the hazard ratio to find out the possible factors influencing risk of death and disease. The 3 year OS of the entire cohort was 56.80% and 3 year DFS was 52.4%. ECS, surgical margin, PNI, LVI and LN size were independent risk factors for poor overall and disease free survival. We identified ECS, positive margin, LVI, PNI and LN size as independent risk factors effecting survival. These factors justify the use of adjuvant radiotherapy or chemo radiation according to the already available guidelines.

Abstract
Management of locally advanced OSCC is multimodal. No single therapy has been proved to be efficacious. However there is a trend towards surgical intervention in operable disease. In this review we appraise the various therapies used for the management of locally advanced OSCC. We review the literature with regards to the various treatment options for locally advanced OSCC. We categorically divided the manuscript into resectable, unresectable and technically unresectable disease. Surgery is the ideal treatment modality for resectable disease. For unresectable disease concurrent chemoradiation appears to improve survival compared to radiotherapy alone. Induction therapy might downstage tumors in the unresectable category. Targeted and Immunotherapy is reserved for recurrent, metastatic or platinum refractory OSCC. Management of locally advanced OSCC is multimodal with surgery playing the primary role. In the event where the tumor is in operable concurrent chemoradiotherapy is regarded as the best treatment modality. Induction chemotherapy currently cannot be recommended for resectable or even unresectable oral squamous cell carcinomas. However for technically unresectable disease it might play a role in improving respectability but it depends on the response of the tumor. Targeted therapy and immunotherapy is currently used for recurrent, metastatic and/or platinum refractory Head and Neck cancers. Currently it is not recommended for initial management of locally advanced disease.

Abstract
AbstractOral cavity cancers contribute to a majority of cancers in India. Clinical examination alone cannot determine the deeper extent of the disease; therefore, need for cross-sectional imaging including computed tomography and magnetic resonance imaging becomes indispensable for pre-treatment evaluation to decide optimal plan of management. Oral cavity squamous cell cancers (OSCC) can be treated with surgery alone, whereas deep muscle, neurovascular, osseous, or nodal involvement on imaging suggests advanced disease that requires a combination of surgery, radiation, and/or chemotherapy. Because of the complex anatomy of the oral cavity and its surrounding structures, imaging is crucial for locoregional staging and early detection of distant metastases. Imaging plays indispensable role not only in diagnosis but also in planning the management. An optimal guideline paper for developing countries like India is lacking that not only helps standardize the management but will also assist oncologists make reasonable decisions and reduce the unnecessary imaging. This imaging guideline paper will discuss the optimal imaging in diagnosis and management OSCC for Indian subcontinent.

Abstract
OBJECTIVES Palliative radiotherapy regimens for advanced head and neck cancers vary in doses and treatment times. Their quality of life (QoL) implications are not clearly established. METHODS We randomised patients with advanced, non-metastatic, head and neck squamous cell carcinomas (stage IVA-B) with WHO performance score of 2 or higher to receive 30 Gy in 10 fractions over two weeks (arm A) or 20 Gy in 5 fractions over one week (arm B). QoL was assessed using European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaires (QLQ)-C30 and QLQ-H&N35 questionnaires at baseline and postradiotherapy. The primary endpoint was the EORTC-defined global health status. Secondary endpoints were functional and symptom scores of QoL, response to radiotherapy and acute toxicities. The primary aim was to evaluate the one-week regimen in terms of QoL to the longer regimen. RESULTS 110 patients were randomised, the number of patients in the final analysis was 95: 49 in arm A and 46 in arm B. Baseline characteristics were similar. Clinical outcomes post-treatment were comparable. Postradiotherapy, there were improved scores for functional and symptom scales, the differences were non-significant. The duration of treatment was significantly reduced in arm B (p<0.01) with a lower score for financial difficulty (p<0.001). The difference in global health status (primary endpoint) was non-significant (p=0.82). The median overall survival was 7 months, the median progression-free survival was 5 months and these did not vary between the two groups. CONCLUSION One-week palliative radiotherapy for head and neck cancers achieves similar QoL and clinical outcomes as more protracted radiotherapy schedules with significantly reduced treatment time and financial toxicity.

Abstract
INTRODUCTION Though the submandibular gland (SMG) is routinely sacrificed for several reasons during neck dissection in patients undergoing curative surgery for oral cavity cancers, it might be an innocent bystander and should be considered for preservation. This study aimed to identify the incidence, different patterns of invasion, and risk factors of SMG involvement in oral cavity squamous cell carcinoma (SCC). METHODS This was a retrospective study of the patients who underwent upfront curative surgery for a biopsy-proven oral cavity SCC. A consistent protocol-based treatment strategy was followed during the study period. Data about clinical profile including demographics, clinical and histology details, and treatment profile were extracted and analysed. RESULTS A total of 303 patients underwent unilateral and bilateral neck dissections contributing 79.2% (n = 240) and 20.8% (n = 63) of patients respectively. The common primary sites were buccal mucosa (n = 129, 42.5%), tongue (n = 100, 33.0%) and alveolar gingiva (n = 52, 17.2%). A total of four SMGs showed tumor involvement resulting in a prevalence of 1.09% per neck dissection (n = 366) and 1.32% per patient (n = 303). Of these four cases of SMG involvement, one patient with alveolar cancer had direct tumor invasion while the other three (alveolar cancer - two, tongue cancer - one) patients had neck node metastasis. CONCLUSION The present study confirms a very low incidence of SMG involvement in patients with oral cavity cancer who undergo neck dissection. It is often observed in patients with high neck node burden (≥N2 disease and the presence of extracapsular spread) or direct invasion by the primary tumor.

Combined proteomic and transcriptomic approaches reveal externalized keratin 8 as a potential therapeutic target involved in invasiveness of head and neck cancers. Transl Oncol 2020; 14:100878.

Abstract
Keratin 8 (K8) expressed at the surface of cancer cells, referred as externalized K8 (eK8), has been observed in a variety of carcinoma cell lines. K8 has been previously reported to be expressed in poorly differentiated head and neck squamous cell carcinoma (HNSCC); however, its role during the invasive phase of upper aerodigestive tract tumorigenesis is unknown. Cohorts of HNSCC tumors for protein and mRNA expression and panel of cell lines were used for investigation. K8 was found to be externalized in a majority of HNSCC cell lines. Among the two main K8 protein isoforms only the 54 kDa was found to be present at the plasma membrane of HNSCC cells. The plasminogen-induced invasion of HNSCC cells was inhibited by the anti-eK8 D-A10 antagonist monoclonal antibody. Overexpression of K8 mRNA and protein were both correlated with tumor aggressive features and poor outcome. The effect of eK8 neutralization on invasion, its presence exclusively in cancer cells and the association of K8 expression with aggressive features and poor clinical outcome in HNSCC unravel eK8 as key player in invasion and a promising therapeutic target in HNSCC.
