“…These factors should be carefully evaluated before a decision is made about the various possible treatment strategies (Swearingen et al, 1966;Slootweg and Muller, 1989;Brown et al, 1994;Nakayama, 2009). Tumours generally develop and grow elliptically.…”

“…Carcinomas of the mandibular gingiva are more common than those of the maxillary gingiva [ 7 ]. Mandibular gingival carcinoma invades the mandible in an early stage [ 8 ]. If it invades the mandible deeply, it cannot be expected to be cured by RT alone because radiation osteoradionecrosis occurs after high-dose RT [ 9 ].…”

Advanced squamous cell carcinoma (SCC) of the mandibular gingiva in elderly patients is difficult to cure. The treatment policy for elderly patients with advanced SCC of the mandibular gingiva has not been clear. We report a case of right mandibular gingival carcinoma that was successfully treated by palliative chemoradiotherapy. An 83-year-old female complained of pain and an ulcer in her right mandibular gingiva. Oral examination revealed a lesion of about 20 mm in size in the right mandibular gingiva. A diagnosis of SCC in the right mandibular gingiva was made by histology. Imaging findings revealed some right neck lymph node metastases. Based on these findings, a clinical diagnosis before treatment was SCC in the right mandibular gingiva (cT4aN2bM0, stage IV) by the 7th edition of the Union of International Cancer Control. She refused to receive definitive surgery or chemoradiotherapy due to concerns about the invasiveness of these definitive therapies and requested palliative chemoradiotherapy. We delivered S-1 (a combination of tegafur, gimeracil, and oteracil) and radiation therapy (RT) to the primary tumor alone with 30 Gy in 10 fractions using 4-megavoltage equipment via a multiple leaf collimator by three-dimensional RT. Although we could not complete the delivery of S-1 because of an acute side effect, the palliative chemoradiotherapy resulted in a complete response, and the lymph node metastases also disappeared. The patient remains in complete remission for 5 years without surgery or chemotherapy. Palliative chemoradiotherapy for elderly patients with mandibular gingival carcinoma is considered to be one of the therapeutic options.

“…Each image slice is created by measuring x-ray attenuation through the tissue. CT is used for oral cancer diagnosis in evaluating the extent of infiltration in the buccal space, bone invasion, and extension to the retromolar trigone (figure 3) [8,[105][106][107]. Several studies have confirmed that CT is reliable in staging malignancy and detecting bone erosion [105,106,108].…”

Oral cancer causes over 350 000 deaths annually worldwide. Although most cases are in Asia, the incidence of oral cancer is rising across the world. Despite recent advances in screening methods, oral cancer remains a significant cause of mortality and morbidity. The 5-year survival rate (50%–60%) has not improved over the past several decades. Early detection and accurate diagnosis of the disease can improve the survival rate and patients’ quality of life. This article provides a topical review of current and emerging techniques for screening and diagnosing oral cancer. Currently available technologies have only been moderately useful towards identifying oral cancer early, motivating the development of novel approaches to address this goal. In this article, we provide an overview of adjunctive screening aids, including biofluid (saliva and serum) diagnostics, vital staining, brush biopsy, chemiluminescence, and tissue autofluorescence. Furthermore, we discuss diagnostic imaging modalities, such as computed tomography, magnetic resonance imaging, positron emission tomography, ultrasound (including traditional B-mode imaging, color Doppler, and elastography), photoacoustics imaging, and optical coherence tomography, and artificial intelligence-based methods, which are either being used clinically or are under development for oral cancer staging. The physical and biological basis underpinning each technique are discussed, along with their advantages and limitations in the technological and clinical context. The review concludes with a discussion of the future perspectives in this rapidly evolving field.
