Introduction: Salivary carcinomas of the tongue represent a therapeutic challenge as their radical excision is particularly mutilating. We aimed to study the oncologic and functional outcomes of advanced stages salivary carcinomas of the tongue.
Materials And Methods: This retrospective multicentric study, based on the French national network on rare head and neck cancers (REFCOR), included all patients with a T3-T4 salivary carcinoma of the tongue, diagnosed between January 2009 and December 2018.
Article Synopsis
- Salivary carcinomas of minor salivary glands, particularly in the tongue, are rare tumors that may require surgery and/or (chemo-)radiotherapy for treatment.
- A study involving 103 patients diagnosed between 2009 and 2018 found that the most common types were adenoid cystic and mucoepidermoid carcinomas, with surgery being the primary treatment for most cases.
- Results indicated that 5-year overall survival was 84.7%, while event-free survival was lower at 38.6%; nonsurgical treatment, alcohol use, and tumor location negatively impacted event-free survival, while nodal positivity was a key factor affecting overall survival.
Circulating tumor DNA (ctDNA) is the cornerstone of liquid biopsy diagnostics, revealing clinically relevant genomic aberrations from blood of cancer patients. Genomic analysis of single circulating tumor cells (CTCs) could provide additional insights into intra-patient heterogeneity, but it requires whole-genome amplification (WGA) of DNA, which might introduce bias. Here, we describe a novel approach based on mass spectrometry for mutation detection from individual CTCs not requiring WGA and complex bioinformatics pipelines.

Methods: This single-center retrospective study included 223 patients who received surgery for a primary OTSCC between January 2017 and December 2021.
Results: Multivariable analysis showed that deep margin distance ≥3 mm in T1-T2 tumors and ≥5 mm in T3-T4 tumors was significantly associated with better RFS and OS.
