Conditions

Thoracic malignant tumors Thoracic malignant tumors

Interventions

This is an interventional study to determine efficaty and safety of 5-ALA to detect thoracic malignant tumors during the surgery. 5-ALA 20 mg/kg will be orally administered 2-4 hours prior to surgery

Design outcomes

Primary

MeasureTime frame
The diagnosis rate of 5-ALA for each resected section of organ - percentage of organs diagnosed as positive by 5-ALA, before resection, among organs diagnosed as malignant via pathological diagnosis (if there are multiple tissue specimens from the same organ, one positive specimen is considered as positive) If there are specimens from more than one organ (lung, pleura, and lymph nodes, etc.), then they will be evaluated individually by organ.

Secondary

MeasureTime frame
1) Consistency of 5-ALA fluorescence results from intraoperative to post-resection 2) Percentage of 5-ALA fluorecence positive (or negative) tissue specimens in cut surface among 5-ALA positive tissue specimens before-resection 3) Percentage of 5-ALA fluorecence positive (or negative) tissue specimens in cut surface among 5-ALA negative tissue specimens before-resection 4) From cut surface, percentage of 5-ALA fluorecence positive (or negative) tissue specimens among tissue specimens diagnosed as malignant via pathological diagnosis 5) Percentage of organs diagnosed as positive in cut surface by 5-ALA among organs diagnosed as malignant via pathological diagnosis 6) (Diagnosis for each resected section of organ) Percentage of organs diagnosed as negative by 5-ALA (either before resection or cut surface) among organs diagnosed as malignant via pathological diagnosis (if there are multiple tissue specimens from the same organ, all negative is considered as negative) 7) (Diagnosis for each resected section of organ) Percentage of organs diagnosed as positive or negative by 5-ALA (either before resection or cut surface) among organs diagnosed as not-malignant via pathological diagnosis 8) (Diagnosis for each resected section of organ) Percentage of organs pathologically diagnosed as malignant among organs considered as malignant via current normal procedure (observation under white light and palpation). 9) (Diagnosis for each resected section of organ) Percentage of organs pathologically diagnosed as not-malignant among organs considered as not-malignant via current normal procedure (observation under white light and palpation). 10) (Diagnosis for tissue specimen - continuous lesion will be counted as one specimen) Percentage of tissue specimens diagnosed as positive or negative by 5-ALA (either before resection or cut surface) among tissue specimens diagnosed as malignant via pathological diagnosis 11) (Diagnosis for tissue specimen) Percentage of tissue specimens d
