RESUMEN
Objective@#To investigate the effect of elective neck dissection on the 5-year survival rate of patients with early oral squamous cell carcinoma.@*Methods@#The data of 100 patients with early oral squamous cell carcinoma (cT1-2N0M0) were retrospectively analyzed. In 61 cases, the primary tumor was subjected to elective neck dissection (END). Neck observation and follow-up (NOF) were performed in 39 cases with enlarged resection of primary lesions. Clinicopathological data such as pT staging, pathology classification,the rate of cervical lymph node metastasis and the 5-year survival rate of the patients were statistically analyzed.@*Results@#The 5-year survival rates of the END and NOF groups were 86.9% and 69.2%, respectively, and the difference was statistically significant (P=0.028). END treatment was significantly better than NOF in controlling cervical lymph node metastasis in early oral squamous cell carcinoma (P=0.009). After stratified analysis of histopathological features, the 5-year survival rate of patients with pathological T2 (pT2) stage OSCC in the END group was significantly higher than that in the NOF group (P=0.020). The 5-year survival rate of patients with moderate and poorly differentiated pathological grade OSCC in the END group was significantly higher than that in the NOF group (P=0.013). @*Conclusion @# END is effective for the management of the cervical lymph node metastasis rate in early OSCC patients. For patients with pT2 stage or low differentiation pathological grade, active END can significantly improve the 5-year survival rate.
RESUMEN
Papillary thyroid carcinomas comprise approximately 80 percent of all thyroid cancers, but haves a good prognosis, with overall survival rates at 10 years of about 80 to 95 percent. They spreads through the lymphatic system, and the lung is the most frequent metastasis site. If distant metastasis is present, the overall survival rate is about 40 percent. Although malignant pleural effusion, with pleural metastasis is a rare complication in patients with papillary thyroid carcinoma, the development of malignant pleural effusion is an extremely adverse prognostic indicator. We recently experienced a case of malignant pleural effusion with papillary thyroid carcinoma. A 54-year-old woman was admitted to the hospital because of dyspnea. A chest X-ray showed massive pleural effusion in the right hemithorax. Previously total thyroidectomy, and iodine-131 therapy had been performed, but a local recurrence and pulmonary metastasis developed 5 years later, accompanied by malignant pleural effusion with pleural metastasis. We performed diagnostic thoracentesis, which confirmed a metastatic papillary thyroid carcinoma. This patient was a rare case of paplillary thyroid carcinoma, in which the disease was represented by a rapid deterioration with malignant pleural effusion. So we report this case with a review of the literature.
