ReviewLobectomy by video-assisted thoracoscopic surgery (VATS) for early stage of non-small cell lung cancer.
Video-assisted thoracoscopic surgery (VATS) provides a new approach for treating early-stage lung cancer. Lobectomy by VATS has many advantages over conventional thoracotomy, such as shorter recovery time, less postoperative pain, and faster resumption of a normal lifestyle. ⋯ Concerns regarding safety, the extent of mediastinal lymph node dissection, and long-term survival have made some surgeons apprehensive of its validity for lung cancer. In this paper, we review the development of thoracoscopy, the present status of VATS for early stage of non-small cell lung cancer (NSCLC), and comparison between VATS and open thoracotomy in the management of NSCLC.

ReviewArsenic in the treatment of newly diagnosed acute promyelocytic leukemia: current status and future research direction.
Acute promyelocytic leukemia (APL) is a subtype of acute myeloid leukemia. In past decades, intensive studies on the biology and treatment of this disease have resulted in a remarkably thorough understanding of its pathogenesis and improvement of treatment outcomes. ⋯ As the most active agent in APL, arsenic directly degrades the PML-RARα fusion transcript, leading to the differentiation and apoptosis of leukemia cells and the potential eradication of APL leukemiainitiating cells (LICs), thus making the disease a potentially curable type of leukemia. More notably, the recent development of oral arsenic compounds may further enhance not only clinical outcomes but also the convenience of patients, which may dramatically change the APL clinical scenario in the near future.
