Malignancy
NO
To evaluate the effectiveness and safety of T-DXd as second-line treatment in real-world patients with initially HER2-positive gastric cancer whose HER2 status has not been reassessed immediately prior to second-line treatment initiation.

Observational
| Not applicable |
| Not applicable |
Male and Female
1) Patients with unresectable advanced or recurrent gastric cancer (gastric adenocarcinoma or gastroesophageal junction adenocarcinoma) that
has progressed after prior chemotherapy
2) Patients diagnosed with HER2-positive gastric cancer prior to first-line therapy based on pathological assessment (IHC 3+ or IHC 2+ and ISH-positive)
3) Patients with a history of receiving first-line chemotherapy including trastuzumab
4) Patients planned to receive T-DXd as second-line therapy
5) Patients who have not undergone HER2 IHC testing between the initiation of trastuzumab in first-line therapy and the initiation of T-DXd in second-line therapy, or patients whose IHC test results were uninterpretable
6) Patients with measurable lesions
7) Patients with an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0-1
8) Patients who have provided written informed consent
1) Patients with a history of hypersensitivity to T-DXd or its components
2) Patients with prior treatment with T-DXd
3) Patients with active multiple primary cancers that are considered by the investigator to potentially affect the evaluation of T-DXd
4) Patients with a history of perioperative treatment who initiated trastuzumab-containing chemotherapy within 6 months after the completion of the perioperative Treatment
5) Patients deemed ineligible for this study by the investigator
