A Registry for People With Lung Cancer

Inclusion Criteria:

Age ≥18 years
Clinical stage I tumor (AJCC 8th edition) suitable for segmentectomy, according to the treating thoracic surgeon

Pathology of NSCLC

o Tissue diagnosis of NSCLC is not required before enrollment. A pathologic diagnosis of NSCLC may be confirmed preoperatively with biopsy, intraoperatively with frozen section, or postoperatively on final pathology.

Patients must undergo segmentectomy for a peripheral lesion ≤2 cm to be included in the primary analysis. Individual ligation of the segmental artery(s) and segmental bronchus is the minimum definition for a segmentectomy. Division of the segmental vein and intraoperative frozen section to assess surgical margins and N1 lymph nodes are strongly encouraged, but the absence of either is not a criterion for exclusion.

Other considerations:

Patients with ground-glass opacities will have their tumor size recorded on the basis of the size of the solid component.
Any non-lung cancer treated in the past with no obvious recurrence or ongoing treatment is not a criterion for exclusion.
The registry study will be monitored by Thoracic Surgery team at MSK.
This study will be in collaboration with the Thoracic Surgical Oncology Group (TSOG) of the American Association for Thoracic Surgery.

Exclusion Criteria:

Actively receiving lung cancer treatment or a history of lung cancer in the previous 5 years
History of chemotherapy or radiation therapy for a previous lung cancer
Synchronous secondary cancer in the lung or elsewhere in the body at the time of surgery
Carcinoid tumors
History of other malignancies within the past 3 years, with the exception of non-melanoma skin cancer, superficial bladder cancer, and carcinoma in situ of the cervix
Actively receiving treatment for other malignancies

Cases of lobectomy in conjunction with segmentectomy from another lobe and ≥2 segmentectomies from different lobes either en bloc or separate will be excluded from the primary analysis.

Multi-segmental resection from the same lobe is not a criterion for exclusion.
