ABSTRACT
OBJECTIVE To study the results of the reoperation for thyroid cancer. METHODS The clinical data of 288 cases who underwent reoperation for thyroid cancer were analyzed retrospectively. There were 69 male and 219 female. There were 249 cases (86.5 %) with papillary adenocarcinoma, 27 cases(9.4 %) with follicle adenocarcinoma, 6 cases (2 %) with medullar cancer, and 6 cases (2 %) with anaplastic cancer pathologically. The types of operation were lobectomy and near total lobectomy. The unilateral or bilateral neck dissections were performed in selected cases. RESULTS Pathological examination reveal that there were 63 cases of cancer residual in the ipsilateral side and 33 cases of the opposite side. The cervical node metastasis were present in 164 cases of patients at the same side. CONCLUSION The ipsilateral side lobaectomy and/or contralateral side near total lobectomy should be employed for the thyroid cancer patients. The neck dissection should be performed in most of the patients.
ABSTRACT
Objective:To investigate the value of the three-dimensional CT reconstruction by computer photo process system for laryngeal carcinoma and control study with pathologic feature. Methods: Fifty patients with laryngeal carcinoma were scanned by helical CT which photos were three-dimensionally reconstructed with a photo processing system,and the images were compared with pathologic feature.Results:Clear three-dimensional photo of the laryngeal was obtained through the reconstruction of the helical CT.The images could be circular fully around the axis of X,Y and Z in order to find the best view of the diagnosis.Ninety-six percentage of the TNM stage of patients according to the images of three-dimensional reconstruction were consistent with the TNM stage after operation.The safe edge was obtained in 98% of the surgery for patients.Good correlations were showed in the images of the three-dimensional reconstruction of the larynx and pathologic specimens.Conclusion:Good consistent of the three-dimensional images of the larynx with pathologic specimen were useful for diagnosis,operation design and education.
