Collection:

Collection ID:	CO002198
Collection Summary:	The patient tissue specimens from 79 NSCLC patients including the two most prevalent histological subtypes adenocarcinoma (ade) and squamous cell (squ) tumor (65 ade patients with age range 36-84; 14 squ patients with age range 49-78) were obtained from Beijing Hospital. Primary tumor tissues, paired adjacent non-cancerous tissues (ANT) (within 2 cm apart from tumor edge) and distant normal tissues (DNT) ( > 2 cm apart from tumor edge) were surgically resected and frozen at −80 °C until metabolite extraction. The study was approved by the Research Ethics Committee of Beijing Hospital (2019BJYYEC-206-02) and also approved by the Ocean University of China (OUC-HM-2022-002).
Sample Type:	Lung
Collection Method:	Surgical resect
Collection Location:	Beijing Hospital
Storage Conditions:	-80℃

Treatment:

Treatment ID:	TR002217
Treatment Summary:	No. Only cancer and noncancerous tissues.

Sample Preparation:

Sampleprep ID:	SP002211
Sampleprep Summary:	Frozen tissue samples were thawed on ice. Each tissue sample was cut into small pieces and accurately weighed. One mL of precooled 80% methanol was added to 100 mg of tissue and the sample mixture was homogenized (60 Hz, 90 seconds). In a tissue homogenizer with precooled module, followed by vortex-mixing for 1 min and incubation at -80 °C for 4 h to allow for sufficient metabolite extraction. Subsequently, the samples were centrifuged at 14,000 × g for 10 min at 4 °C, and the supernatant was collected and dried under vacuum. Sample blanks were prepared using water following the same experimental procedure. Before analysis, dried metabolites were reconstituted with 100 μL LC-MS grade water, vortex-mixed, and centrifuged at 14,000 × g for 10 min to remove insoluble particles prior to UPLC-HRMS analysis. Quality control (QC) samples were prepared by pooling a small volume from samples with enough volume.
