The article presents a 35-year survey of 293 lung cancer operations performed by one surgeon. Lobectomy had a 3.5% mortality rate and 41% 5-year survival. Simple pneumonectomy had a 20% mortality rate and 30% 5-year survival. Radical pneumonectomy had a 15.25% mortality rate and 39% 5-year survival. Long-term survival rates were impressive, with some patients surviving over 30 years. The survival of patients with involved lymph nodes was discussed, showing that at least one in three patients survived 5 years after surgery. The article emphasizes the importance of the cancer's cell type, with squamous-cell growths having the best results and oat-cell and small-cell growths the worst. It also notes that post-operative pleural infections may improve long-term survival. Radiotherapy was found to be less effective than surgery for long-term survival. The article concludes that lung cancer is a common and deadly disease, but long-term survival is possible in many cases, and that biological factors play a significant role in survival. The author emphasizes the importance of individualized treatment and the need for further research into biological factors in cancer treatment. The article also discusses the development of new lung cancers in patients who have been cured of one, and the importance of not resuming smoking after treatment. The article concludes that while surgery is the best treatment for lung cancer, further research is needed to improve outcomes.The article presents a 35-year survey of 293 lung cancer operations performed by one surgeon.
