  • Purpose: This study was conducted to develop and evaluate an oral care protocol for cancer patients receiving chemotherapy. Methods: The participants in this study were cancer patients in Severance hospital in Seoul. A total of 31 patients were assigned to the experimental group, and 29 patients to the control group. Data were collected from August 1 to October 5, 2010. The protocol included definition and symptom of oral mucositis, self-check method of oral status, prophylactic method of oral mucositis (oral care, eating habits, and gargling) and management of oral mucositis. Oral Assessment Guide (OAG) was used as the measurement tool of oral mucositis in this study, Oral Care Performance Scale was used as the measurement tool of oral care performance status. Data were analyzed with a $x^2-test$ and t-test, and repeated measures ANOVA, using SPSS/WIN 18.0 program. Results: Patients in the experimental group receiving the oral care protocol had a significant difference (t=-2.938, p=.005) in the oral care performance compared to the control group. However, there was no significant difference (F=1.255, p=.274) in the oral mucositis status between two groups. Conclusion: This study showed that the oral care protocol could improve oral care performance status for the patients under chemotherapy.

  • Oral cancer surgery typically consists of resection of lesion, neck dissection and reconstruction, and it has an impact on the position of hyoid bone. Therefore, morphological change of airway can occur since the geometric parameter of airway is correlated with the hyoid bone. Airflow is affected by geometry of the airway. In this study, flow characteristics were compared between pre- and post-surgery models by both particle image velocimetry (PIV) and numerical simulation. 3D model of upper airway was reconstructed based on CT data. Velocity is accelerated by the reduced channel area, and vortex and recirculation region are observed in pre- and post-surgery models. For the post-surgery model, high pressure distribution is developed by significantly decreased hydraulic diameter, and the longitudinal flow stream is also interrupted.

  • In the United States, about 40,000 new cases of oral cancer are diagnosed each year and nearly 7,800 patients died from it in 2012. Omega-3 polyunsaturated fatty acids have been found to have anticancer effects in a variety of cancer cell lines and animal models, but their effect in oral cancer remains unclear. This study was designed to examine the effect of docosahexaenoic acid (DHA, a kind of omega-3 fatty acid) on oral cancer cells and the molecular mechanism of its action. We found that exposure of squamous cell carcinoma-4 (SCC-4) and squamous cell carcinoma-9 (SCC-9) human oral cancer cells to DHA induced growth inhibition in a dose- and time-dependent manner. Meanwhile, in addition to the elevated levels of apoptotic markers, such as cleaved PARP, subG1 portion and TUNEL-positive nuclei, DHA led to autophagic vesicle formation and an increase in autophagic flux, indicating the involvement of both apoptosis and autophagy in the inhibitory effects of DHA on oral cancer cells. Further experiments revealed that the apoptosis and autophagy induced by DHA were linked to inhibition of mammalian target of rapamycin (mTOR) signaling by AKT inhibition and AMP-activated protein kinase (AMPK) activation in SCC-9 cells. Together, our results suggest that DHA induces apoptosis- and autophagy-associated cell death through the AMPK/AKT/mTOR signaling pathway in oral cancer cells. Thus, utilization of omega-3 fatty acids may represent a promising therapeutic approach for chemoprevention and treatment of human oral cancer.

  • The present study investigated the anti-proliferate and anti-invasive of Phorbol 12-myristate 13-acetate (PMA)-induced matrix metalloproteinase (MMP-2) and MMP-9 activities of combined treatment with cisplatin and ethyl acetate fractions of Paeonia japonica. Cell Proliferation was detected by the MTS assay and the activity and mRNA expression of MMP-2/-9 were examined by zymography and RT-PCR. As results, cisplatin or p. japonica treatment of YD-10B cells resulted in a dose-dependent inhibition of cell growth. Also, the viability of YD-10B cells treated with combination of 200 μM cisplatin and 50 ㎍/ml p. japonica was inhibited to 50% in compared with the cisplatin alone. In PMA-treated YD-10B cells, co-treatment of 200 μM cisplatin with 50 ㎍/ml p. japonica significantly inhibited mRNA expression and protein activation of MMP-2/-9. Therefore, This study suggest that the combination treatment of cisplatin and p. japonica potentiates a promising anti-invasive agent and has more potential anti-cancer drug for oral cancer therapy than cisplatin alone.
