Stage 1 and 2

• California Cancer Registry• 19702 patients Stage I• 1432 no treatment

Chest. 2007 Jul;132(1):193-9.

Operated X not treated

Chest. 2007 Jul;132(1):193-9.

Therapeutic Alternatives• Surgery• Lobectomy• Segmentectomy

• Stereotaxic Radiotherapy• Percutaneous Ablation

Guidelines• Resection is the gold-standard treatment

LobectomyPneumonectomy

SD: Stable diseaseOR: objective response

Technical Aspects

Type of Resection

• Lobectomy is the gold-standard

• Segmentectomy (preferred) or wedge resection in

patients with:

• Poor pulmonary reserve or major comorbidity

• Peripheral nodule < 2cm and:

• AIS histology

• >50% ground-glass appearance

• Long doubling time >400 days

Why Lobectomy?

Wedge resectionSegmentectomyLobectomy

Ann Thorac Surg 1995;60:615-622

• Clinical trial: 247 patients:• T1 N0 Lung Cancer (intraoperative staging)• Two Arms:

• Lobectomy• Sublobar resection

•Outcomes:• Local Recurrence• Disease-free survival

Sublobar resection is associated with a higher rate of local recurrenceConclusion

Lobectomy is the gold-standard

• Enrollment: late 1980s, early 1990s• CT Scan• Staging methods

New challenges• Small nodules• Elderly patients• Ground-glass opacities

Is lobectomy really necessary?
