INTERVENTIONAL
Conditions
Summary
Lung cancer patients undergoing upfront surgery, highly benefit from a systematic lymph node dissection in the mediastinum and in the surgical specimens. The latter is performed by the pathologist. Developing a standardized technique to dissect the lobectomy specimen has the potential of maximizing the retrieval of all N1 stations lymph nodes. The investigators believe that the adoption of such technique will improve lung cancer staging and identify a higher number of patients that qualify for adjuvant therapies.
Eligibility
Inclusion Criteria4
- Subjects with a lung nodule or mass who are eligible to undergo a lobectomy.
- Subject without any metastasis present.
- Subjects who have peripheral lung nodule location
- Subjects must be 18 years of age or older.
Exclusion Criteria2
- Subjects who received preoperative chemotherapy or radiotherapy.
- Subjects who have a lung nodule located in a central location. Central tumors are defined by those infiltrating the lobar airway.
Interventions
A lobectomy specimen's resection will undergo systematic lymph node dissection either by the patient's treating thoracic surgeon and/or by a member of the pathology team. The protocol for a standardized lymph node dissection consists of a series of blunt peribronchial dissections starting from the hilum to the periphery, with particular attention to points of airway bifurcation where intrapulmonary lymph nodes aggregate. By emphasizing the intrapulmonary lymph node map and a standardized dissection, the team will remove more lymph nodes from the lobectomy specimen, resulting in an accurate N staging.
