Multicenter Study
Tobacco smoking, alcohol drinking, betel quid chewing, and the risk of head and neck cancer in an East Asian population.
The smoking prevalence among men in China is high, but the head and neck cancer incidence rates are low. This study's purpose was to investigate the impact of tobacco, betel quid, and alcohol on head and neck cancer risk in East Asia. ⋯ Betel quid chewing is the strongest risk factor for oral cavity cancer in this Chinese population. Alcohol may play a larger role for head and neck cancer in this population than in European or U.S.

Recent guidelines advocate unilateral thyroidectomy for low-risk 1-cm to 4-cm differentiated thyroid cancer (DTC). This study was designed to examine the association between the extent of thyroidectomy and oncologic outcomes in patients with 1-cm to 4-cm DTC. ⋯ Although extent of thyroidectomy does not affect DSS, total thyroidectomy is beneficial for reducing recurrence in patients with 1-cm to 4-cm DTC. However, if such tumors have such low-risk features as being unifocal, intrathyroidal, and lymph node metastasis-negative, extent of thyroidectomy does not affect oncologic outcome and lobectomy may be sufficient.
