Lung cancer
• Responsible for about one-third of all cancer deaths
• Accounts for more deaths than breast cancer, prostate cancer and colon cancer COMBINED
• ~85% of patients who develop lung cancer will die of the disease

Surgery
• Lobectomy is a golden standard, sublobar resections (segmentectomy or wedge resections) should be reserved for patients with compromised pulmonary function
• Sublobar resections are currently evaluated vs. lobectomy in tumors <2 cm in clinical trials
• Pneumonectomy should be avoided, but this is sometimes not possible
• VATS procedures are common in tumors <4 cm (decreased pain and faster recovery)

Stage III NSCLC
• Up to 30% of NSCLC patients present at diagnosis with stage III disease
• Most of them are not amenable for primary surgery
• Results following surgery or radiotherapy as a single modality alone are poor
• Multimodality therapy increases outcomes

Stage IIIA (N2): conclusions• Pulmonary resection after response
to induction chemotherapy or chemoradiotherapy does not improve survival
• Combined chemotherapy and radiotherapy remains the standard treatment in the majority of stage III (N2) patients. Surgery is considered for very selected patients in specialized centers (e.g. single stage N2)
• Current clinical trials evaluate induction chemo-immunotherapy followed by surgery
