Inclusion Criteria:
- Willing to participate in this study.
- Age >18 years; both sexes are eligible.
- Histologically confirmed gastric adenocarcinoma or gastroesophageal junction adenocarcinoma.
- Resectable locally advanced disease as assessed by imaging and/or multidisciplinary team evaluation, generally corresponding to AJCC 8th edition stage II-III disease, including cT3-4a with any N category or any T with node-positive disease, without distant metastasis.
- Planned to receive neoadjuvant therapy followed by curative-intent surgery.
- Eastern Cooperative Oncology Group (ECOG) performance status of 0-1.
- No prior systemic antitumor treatment for the current tumor at baseline.
- Able to understand and complete questionnaire assessments.
- Able and willing to provide written informed consent.
Exclusion Criteria:
- Presence of distant metastasis, peritoneal metastasis, or loss of curative treatment opportunity as determined by clinical evaluation.
- Prior neoadjuvant chemotherapy, immunotherapy, radiotherapy, or other systemic antitumor treatment for the current tumor.
- Severe cognitive impairment, acute psychiatric disorder, or any condition that precludes completion of questionnaire assessments.
- Current treatment with antidepressants, anxiolytics, or other psychotropic medications with any of the following within 4 weeks before baseline assessment: initiation, discontinuation, change in medication type, dose adjustment of 50% or more, or addition of a second or more psychotropic medication.
- Any other condition judged by the investigator to make the participant unsuitable for enrollment.

Pretreatment Emotional Distress
Participants with pretreatment emotional distress, defined as a PHQ-9 score of 5 or higher and/or a GAD-7 score of 5 or higher before initiation of perioperative immunotherapy.
These participants will receive standard perioperative immunotherapy and routine clinical care according to the treating physician's plan.
This observational study will compare pathologic response and clinical outcomes between participants with and without pretreatment emotional distress.

No Pretreatment Emotional Distress
Participants without pretreatment emotional distress, defined as a PHQ-9 score lower than 5 and a GAD-7 score lower than 5 before initiation of perioperative immunotherapy.
These participants will receive standard perioperative immunotherapy and routine clinical care according to the treating physician's plan.
This observational study will compare pathologic response and clinical outcomes between participants with and without pretreatment emotional distress.

Pathological Complete Response (pCR)
Zeitfenster: Assessed on surgical pathology at the time of curative resection, approximately 6 to 12 weeks after initiation of perioperative immunotherapy

Pathological complete response is defined as the absence of residual viable tumor cells in the resected primary tumor and all examined regional lymph nodes after completion of neoadjuvant immunotherapy and curative surgery.
|
Assessed on surgical pathology at the time of curative resection, approximately 6 to 12 weeks after initiation of perioperative immunotherapy

|
Event-free survival is defined as the time from study enrollment to the first occurrence of any of the following events: disease progression during neoadjuvant treatment, failure to undergo curative surgery, postoperative recurrence, or death from any cause.
|
From enrollment up to 24 months
|
|
Overall Survival (OS)
Zeitfenster: From enrollment up to 36 months
