When is surgery considered?
The decision to operate depends on the tumor’s type, location and stage, and the person’s ability to tolerate surgery. Surgery is an important treatment option particularly for suitable early-stage non-small cell lung cancers. Not all lung cancers are treated surgically; the extent and biological characteristics of the disease can change the treatment plan.
Diagnosis, staging and multidisciplinary review
The extent of disease is investigated with CT and, when needed, PET-CT, brain imaging and tissue examinations. Lymph node sampling with methods such as EBUS or mediastinoscopy may be necessary. Assessments by thoracic surgery, respiratory medicine, medical oncology, radiation oncology, radiology and pathology are considered together.
Breathing capacity and preparation for surgery
Lung function, heart health and coexisting illnesses are assessed. Exercise capacity and predicted postoperative lung function may be evaluated when needed. Stopping smoking, nutrition and an activity plan are part of preparation. Do not stop medication on your own; obtain individual preparation instructions from your treatment team.
Anatomical lung resections
Lobectomy removes one lobe of the lung; segmentectomy removes one or more anatomical segments; pneumonectomy removes an entire lung. Wedge resection is a limited removal that does not follow anatomical segment boundaries. The appropriate extent depends on tumor size and location, adequate surgical margins, lymph nodes and breathing capacity. Not every small tumor requires the same operation.
VATS, robotic or open surgery
VATS and robotic surgery are approaches that access the chest through small incisions. Open surgery may be more appropriate for some patients. The approach and the amount of lung to be removed are separate decisions. A minimally invasive operation may be converted to an open approach for safety or adequate tumor removal.
Lymph nodes and pathology
Assessment of lymph nodes during surgery affects staging and subsequent treatment decisions. Pathology provides information about tumor type, surgical margins and lymph node involvement. Molecular tests may also contribute to treatment selection in appropriate cases.
Additional treatments and alternatives
Some patients may receive chemotherapy, immunotherapy, targeted therapy or radiotherapy before or after surgery. If surgery is unsuitable, radiotherapy and systemic treatments may be considered according to the disease characteristics. The sequence and combination of treatments are individualized.
Risks, recovery and follow-up
Risks such as bleeding, prolonged air leakage, infection, abnormal heart rhythms, blood clots and respiratory failure are assessed. Pain control, breathing exercises and appropriate activity are important. Follow-up is planned according to pathology and treatment. Call 112 in Türkiye for sudden severe breathlessness, fainting or severe chest pain.
Frequently asked questions
Will I need additional treatment after surgery?
It may be needed depending on pathology, stage and tumor characteristics; surgery alone is not sufficient for every patient.
Is removing less lung always better?
Preserving lung tissue is important, but adequate tumor removal and surgical margins must also be achieved.
Does minimally invasive surgery change the cancer stage?
No. VATS and robotic surgery are surgical approaches; stage is determined by the extent of disease.
