Abstract:
?Objective: To estimate the effect of carboplatin activiated carbon particle delivery system (CP CH) in the treatment of oral carcinoma and its cervical lymph node metastasis. Methods: CP CH was prepared by absorption of carboplatin with activated carbon particles and injected into the submucosa around the tumors 72 h before operation in 6 patients with tongue or buccal squamous cell carcinoma (SCC) and metastasis in cervical lymph nodes,then extensive tumorectomy with neck dissection was conducted. The specimens of lymph nodes,primary carcinoma and blood were analyzed by microscope and plasma emitting spectrometry. Results:60 out of 70 (83.33%) lymph nodes obtained from the CP CH treated cases were found to be stained black by carboplatin.The carboplatin concentrations in lymph nodes and blood were (23.36 ?2.58) ?g/g and (1.76?0.32) ?g/ml respectively.Necrosis and degeneration were observed in SCC tissue.Conclusion:CH CP may be effective in the treatment of oral SCC with cervical lymph metastasis by providing high concertration and long lasting carboplatin in the lessions.
