Abstract
The aim of this study was to investigate the survival effect of palliative surgery in advanced tongue squamous cell carcinoma (TSCC). A retrospective analysis of data in the SEER database for 6151 patients with stage III/IV TSCC (American Joint Committee on Cancer (AJCC) staging), diagnosed between 2004 and 2015, was performed. The patients were divided into two groups: palliative surgery and no surgery. Kaplan–Meier and Cox proportional hazards regression analyses were applied to determine risk factors for overall survival (OS) and cancer-specific survival (CSS). A further analysis was performed using 1:1 propensity score matching (PSM) to balance 13 patient variables (sex, age at diagnosis, race, marital status, primary tumour site, SEER stage, AJCC stage, pathological differentiation grade, tumour size, lymph node metastasis, previous lymph node removal, radiotherapy, and chemotherapy). Among the 6151 patients, 706 underwent palliative surgery; the other 5445 did not undergo any kind of surgery. Those who underwent palliative surgery had a higher 5-year survival rate. After PSM, 1274 patients were included in the matched cohort. Multivariate Cox regression analysis showed that patients who underwent palliative surgery had a lower risk of death than those who did not (OS: hazard ratio 0.58, 95% confidence interval 0.49–0.69, P < 0.001; CSS: hazard ratio 0.60, 95% confidence interval 0.49–0.74, P < 0.001). In this comparative study it was found that compared with no surgery, palliative surgery has a positive impact on the survival rate of patients with advanced TSCC.

- The efficacy of neoadjuvant chemotherapy as compared to upfront surgery for the management of oral squamous cell carcinoma: a systematic review and meta-analysisInternational Journal of Oral and Maxillofacial SurgeryApril 21, 2023
- PreviewThe efficacy of neoadjuvant chemotherapy in the field of head and neck oncology has always been debated. The aim of this study was to determine the efficacy of neoadjuvant chemotherapy followed by surgery in patients with oral squamous cell carcinoma (OSCC) by comparison to upfront surgery, in terms of overall survival, disease-free survival, response rates, positive surgical margins, loco-regional recurrence, distant metastasis, and toxicity. Prospective and retrospective studies were identified from a search of the PubMed, PubMed Central, and Cochrane Library databases (publication date between January 1, 1995 and January 1, 2022), as well as hand searches.

- PreviewThere have been no prior studies examining the effect of distance to the treatment centre on oral squamous cell carcinoma outcomes in Australia. The purpose of this study was to analyse the impact of travel distance on oral tongue squamous cell carcinoma (OTSCC) outcomes. This was a retrospective analysis of 243 patients who received surgical treatment ± adjuvant therapy between 2007 and 2016. The overall survival (OS), disease-specific survival (DSS), and freedom from loco-regional failure (FFLRF) survival analyses were conducted using Kaplan–Meier curves and a multivariate Cox proportional hazards model.

- The impact of lymph node density as a predictive factor for survival and recurrence of tongue squamous cell carcinomaInternational Journal of Oral and Maxillofacial SurgeryJuly 21, 2021
- PreviewThe oral tongue is considered the most frequently involved site in cases of oral squamous cell carcinoma (OSCC). Lymph node (LN) density, defined as the number of positive LNs divided by the total number of resected LNs, is considered an important prognostic factor in OSCC; however the cut-off point remains uncertain. A retrospective study was performed involving 104 patients who underwent a glossectomy procedure for oral tongue squamous cell carcinoma (OTSCC) between the years 2008 and 2018. LN density and other related prognostic factors, including pathological N-stage (pN), extranodal extension (ENE), perineural invasion (PNI), and depth of invasion (DOI), were investigated in relation to survival and recurrence rates.

Fluorescence visualization and iodine solution are able to detect oral epithelial dysplasia and surrounding oral cancer. The purpose of this study was to clarify the effectiveness of combining fluorescence visualization and iodine solution-guided surgery for early tongue cancer. Participants comprised 264 patients with primary early tongue cancer who underwent surgery. The surgical margin was set at 10 mm outside the clinical tumour, and 5 mm outside the area of fluorescence visualization loss, and 5mm outside the iodine unstained area.
