AI Article Synopsis
- Postoperative recurrence of tongue squamous cell carcinoma (TSCC) is a significant issue for both patients and doctors, as traditional treatments like surgery and radiotherapy can lead to functional impairments and severe side effects.
- A clinical case study evaluated the use of Microdrop aminolevulinic acid (ALA) photodynamic treatment (PDT) in a patient with TSCC, involving a specialized injection method and follow-up assessments at 1 and 4 months.
- Results showed no visible lesions or recurrence after treatment, preserving the patient's tongue function and cosmetic appearance, suggesting that Microdrop ALA-PDT could be a valuable alternative treatment option for select TSCC cases.
Article Abstract
Background: Postoperative recurrence of tongue squamous cell carcinoma (TSCC) has always been a clinical problem for patients and doctors. Surgery and radiotherapy are the main treatment methods for TSCC, but reoperation often leads to functional impairment. Side effects of radiotherapy include mucosal gland damage, dry mouth, weakened or lost taste. Improved treatment is needed.
Objective: To evaluate the clinical outcome of a patient with TSCC treated with Microdrop aminolevulinic acid (ALA) photodynamic treatment (PDT) twice.
Methods: ALA was dissolved in 5 % lidocaine and the concentration of ALA was 20 % by Microdrop method. Then, the tumor tissue was expanded 1 cm outward, and the injection points were evenly distributed with an upper and lower left and right interval of 2-3 mm. The 1 ml syringe was used to perform the injection in the skin of the tumor area, and there was a small cuticle at each injection point. A pathologically confirmed patient with TSCC received twice Microdrop ALA-PDT treatments, which were evaluated at 1 month and 4 months later.
Results: After 3 h of Microdrop ALA injection, the wavelength of semiconductor laser was set to 630 nm, and the energy of 300 mW /cm was irradiated for 30 min. After two treatments, the lesions were not visible, and no recurrence occurred after 4 months of follow-up. The patient's tongue function was well preserved and the cosmetic effect was good.
Conclusion: Microdrop ALA-PDT may be effective in the salvage treatment of select tongue squamous cell carcinoma.

Objective: To investigate the clinical manifestations of head and neck cancer in patients with Plummer-Vinson syndrome (PVS) and to assess related oral comorbidities.
Materials And Methods: Case reports covering head and neck cancer manifestations in patients diagnosed with PVS were included Studies were identified through seven main electronic databases (PubMed/MEDLINE, EMBASE, Scopus, Web of Science, CINAHL, LILACS, and LIVIVO), and a search for gray literature was performed using ProQuest Dissertations and Theses and Google Scholar. Independent reviewers applied predefined eligibility criteria in a two-phase selection process.

We report an unusual case of a 39-year-old male patient with a previous history of treated classical Hodgkin lymphoma, presenting with tongue ulcer and left ear pain who was subsequently diagnosed with invasive squamous cell carcinoma of the oropharynx. This case highlights the importance of vigilance in patients with a history of lymphoma and the potential for the development of secondary malignancies. We discuss the clinical, radiological, and pathological findings and emphasize the need for close monitoring and early intervention in such cases.

The development of efficient platforms for the evaluation of anti-angiogenic agents is critical in advancing cancer therapeutics. In this study, we exploited an ultrabright semiconducting polymer dots (Pdots) integrating with a three-dimensional (3D) near-infrared-II (NIR-II) fluorescence imaging system designed to assess the efficacy of potent anti-angiogenic agents PX-478 and BPR0C261 in an oral squamous cell carcinoma (OSCC) tumour model, which depends on angiogenesis for dissemination. PX-478, a hypoxia-inducible factor-1α (HIF-1α) inhibitor, and BPR0C261, a microtubule-disrupting agent, were administrated into tumour-bearing mice established using murine MTCQ1 tongue cancer cells through intraperitoneal injection and oral gavage, respectively.

Background: The objective of this study is to assess the association between age and lymph nodes metastasis (LNM) in T1 oral tongue squamous cell carcinomas (OTSCC) patients.
Methods: Patients with T1 OTSCC were extracted from the SEER database between 2005 and 2014. Univariate and multivariate logistic regression models were produced to recognize the association between age and risk factors of LNM.

Department of Oral and Maxillofacial Diseases, University of Helsinki, Helsinki, Finland.
Objective: Oral tongue squamous cell carcinoma is an aggressive life-threatening disease, the prognosis of which is affected by tumor stage and size. We retrospectively studied whether oral inflammatory burden and established tongue carcinoma etiological factors exert an impact on tumor size and stage.
Materials And Methods: Medical records of 183 subjects diagnosed with tongue carcinoma at Helsinki University Hospital were investigated.
