  • Lung cancer is the most common cause of cancer death in Japan, exceeding that of the other five cancers combined (colon, pancreas, stomach, liver, and breast). Symptoms often do not appear until the disease is advanced, and the symptoms also can be mistaken for other health conditions. Accordingly, the mortality of lung cancer has remained high due to a disproportionate presentation of lung cancer at an advanced, usually incurable stage. The 5-year overall survival exceeded 20% in only three countries: Japan (30%), Israel (24%), and Mauritius (37%). 1)

Surgery for lung cancer

VATS lobectomy (our main procedure for lung cancer)
  • Non-small cell lung cancer (NSCLC) accounts for 80% of lung cancer cases. Surgical resection is the standard treatment for early stage NSCLC, and patients operated on for Stage IA tumors now have a survival of approximately 80%. Reports have indicated that long-term outcomes of clinical Stage I NSCLC remain unchanged when surgery is performed via thoracotomy or thoracoscopy. Moreover, close to 80% of all lung cancer patients in Japan who are eligible for surgery are in Stage I 2), so thoracoscopic surgery is being more often to treat lung cancer in Japan. Video-assisted thoracoscopic surgery (VATS) with hilar/mediastinal lymph node dissection for primary lung cancer has become more popular over the last few decades, and it has been reported that patients treated with this procedure experience significantly lower the incidence of postoperative complication and shorter duration of the postoperative drainage compared with thoracotomy cases. 3)
