Lung Cancer Surgery Basics
- Tumor malignancy is confirmed through biopsy and pathology analysis.
- Operability depends on clinical staging from preoperative imaging.
- Post-surgery systemic treatment is determined by pathological staging.
- Follow-up with CT imaging varies based on pathological staging.
Criteria for Lung Cancer Surgery
To answer this, it’s important to understand the types of lung lesions and which require further tissue diagnosis and a surgical plan.
GGO, Lung Nodules, and Lung Tumors
These terms describe imaging characteristics of lung lesions on CT scans:
‧GGO: Lesions denser than normal lung tissue, appearing hazy like frosted glass on imaging.
‧Lung Nodules: Lesions smaller than 3 cm.
‧Lung Tumors: Lesions larger than 3 cm.
These terms do not confirm malignancy. A tissue biopsy and pathological analysis are required to determine if a lesion is cancerous.
Malignancy Risk
Based on data from Mount Sinai Medical Center, the risk of malignancy within a year increases with lesion size:
‧>0.5 cm: 3.5% risk within one year
‧>0.6 cm: 5.5% risk within one year
‧>0.7 cm: 7.5% risk within one year
‧>0.8 cm: 10.4% risk within one year
‧>0.9 cm: 13.2% risk within one year
Lesions over 0.7–0.8 cm carry a higher malignancy risk and should be evaluated further.
Lymph Node Metastasis Risk
The risk of lymph node metastasis increases with tumor size, impacting prognosis:
‧<1 cm: 3.8% risk
‧1–2 cm: 16.7% risk
‧2–3 cm: 19.6% risk
‧>3 cm: 37% risk
Tumors smaller than 1 cm, even if malignant, carry a lower risk of lymph node involvement.
Timing for Tissue Biopsy
Studies show that lesion size is closely linked to malignancy risk.
It is medically recommended to perform a tissue biopsy for definitive diagnosis when the lesion reaches 0.7–0.8 cm or larger.
Tumor Staging Assessment
‧Use imaging to determine if the lesion is suitable for curative resection.
‧Evaluate heart and lung function to ensure sufficient lung volume remains for normal breathing post-surgery.
Pre-Surgery Instructions
‧Practice lung recovery exercises using a spirometer.
‧Avoid food and water after midnight the day before surgery.
Surgical Planning
‧Create 3D imaging of lung lesions pre-surgery.
‧Use CT-guided localization for target lesions.
Post-Surgery Care
‧Care for surgical wounds.
‧Use pain medication to manage discomfort and support thoracic rehab.
‧Practice lung recovery with a spirometer.
‧Train to cough effectively to clear airway secretions.
‧Monitor chest tube drainage for air leaks, subcutaneous emphysema, or chylothorax.
‧Encourage mobility to prevent postural hypotension.

Lung Cancer Resection Q&A
Lung cancer symptoms require tailored surgeries. Find answers to common questions here:
What are the types of lung cancer surgeries?
‧By incision size: Minimally invasive/Open surgery
‧By technique: Thoracoscopic/Robotic surgery
‧By resection scope: Wedge resection/Segmentectomy/Lobectomy
Hospital Stay for Lung Cancer Surgery?
Around 5–8 days, including 3–5 days for preoperative preparation and 2–3 days for recovery.
Are there any postoperative complications?
Common thoracic surgery complications, which mostly are manageable with medication:
‧Air leaks/Subcutaneous emphysema (chest or neck)/Voice changes
‧Chylothorax
‧Lung collapse
‧Chest wound pain or numbness
‧Persistent cough
Why can’t some lung cancer patients undergo surgery?
There are two main reasons:
‧The tumor has spread to vital chest structures, contralateral mediastinum, supraclavicular lymph nodes, or distant sites (stages 3B or 4), making complete resection impossible.
‧The tumor is resectable, but the patient’s heart and lung function cannot tolerate the loss of lung capacity caused by surgery.
Can lung cancer be surgically removed?
Surgical eligibility depends on tumor severity, assessed through imaging for tumor size, lymph node involvement, and metastasis.
Patients with stage 3A or lower, where the tumor is confined to the same side of the chest without critical structure invasion, may undergo complete resection if heart and lung function allow.
Is Post-Surgery Treatment Needed?
Post-surgery treatment depends on pathological staging:
‧Stage 1A1: Regular follow-ups only.
‧Stage 1A2 or 1A3: Follow-up or optional additional treatment.
Stage 2 or higher: Typically 4–6 cycles of chemotherapy with regular check-ups.
If recurrence risks are found, additional chemotherapy may be advised.
Differences Between Clinical and Pathological Staging
Clinical Staging
‧Uses CT, PET, and MRI. for initial evaluation.
‧Evaluates tumor size, lymph nodes, and metastasis.
‧Based on imaging, suited for non-surgical patients.
‧Limited by imaging, unable to detect microscopic lesions.
Pathological Staging
‧Requires tumor removal and microscopic analysis.
‧Assesses tumor invasion and guides treatments.
‧More precise for planning further care.
Is Lung Cancer Surgery Successful?
Lung cancer surgery success depends on preoperative evaluation and patient factors like heart-lung function.
Most tumors can be fully removed, with less than 1% risk of discovering metastasis requiring a treatment change.
Breathing issues post-surgery are uncommon. Vascular injury during vessel ligation occurs in about 1% of cases, which may require open surgery for repair.
