The content of cadmium, cobalt and nickel in laryngeal carcinoma

摘要: Introduction The aim of the study was to determine content cadmium (Cd), cobalt (Co) and nickel (Ni) in samples from laryngeal carcinoma comparison with level these elements healthy mucous membrane same larynx. Material methods conducted on 43 patients carcinoma. levels Cd, Co, Ni control tissues determined by inductively coupled plasma optical emission spectrometry (ICP - OES) using sequential spectrometer. Results No significant differences were found between vs without However, it noted that concentration Cd tumors metastases cervical lymph nodes significantly higher than metastases. Co more advanced tumors: stage-T4 stage T3. It is interest rural urban areas. Conclusions imbalance nickel, cancer may be due a changed cellular metabolism process. results our reveal metals areas which suggests this fact related environmental or occupational factors therefore requires further study.
