Opis
Inclusion Criteria:
- Age greater than 18 years, regardless of sex.
- Histologically confirmed gastric adenocarcinoma or gastroesophageal junction adenocarcinoma.
- Locally advanced, resectable disease as assessed by imaging or a multidisciplinary team, based on the 8th edition of the AJCC staging system, typically cT3-4a, any N, or any T with N-positive disease, corresponding to stage II-III disease, without distant metastasis.
- Scheduled to receive neoadjuvant therapy followed by radical surgery.
- Eastern Cooperative Oncology Group performance status (ECOG PS) of 0-1.
- No prior systemic anticancer therapy for the current tumor at study baseline.
- Willing to participate in the study and able to provide written informed consent.
Exclusion Criteria:
- Presence of distant metastasis, peritoneal metastasis, or disease considered no longer suitable for curative-intent treatment.
- Prior neoadjuvant chemotherapy, immunotherapy, radiotherapy, or other systemic anticancer therapy for the current tumor.
- Severe cognitive impairment, acute psychiatric disorder, or any other condition that prevents the participant from completing study procedures.
Current treatment with antidepressants, anxiolytics, sedative-hypnotics, or other psychotropic medications, with any of the following occurring within 4 weeks before enrollment:
- Increase or decrease in the dose of the relevant medication by 25% or more from the previous maintenance dose;
- Initiation, discontinuation, or replacement of antidepressants, anxiolytics, sedative-hypnotics, or other psychotropic medications;
- Adjustment of treatment due to worsening anxiety, depression, insomnia, or other psychiatric or psychological symptoms;
- Any medication change or psychological condition judged by the investigator to potentially affect sleep monitoring results or study compliance.
- Any other condition that, in the opinion of the investigator, makes the participant unsuitable for this study.

Poor Objective Sleep Characteristics Group
Participants whose objective sleep characteristics during neoadjuvant immunotherapy are below the predefined median threshold, based on device-estimated deep sleep proportion or a predefined objective sleep composite index.
This group is classified as having poor objective sleep characteristics for observational analysis only.

Favorable Objective Sleep Characteristics Group
Participants whose objective sleep characteristics during neoadjuvant immunotherapy are at or above the predefined median threshold, based on device-estimated deep sleep proportion or a predefined objective sleep composite index.
This group is classified as having favorable objective sleep characteristics for observational analysis only.

Major pathological response (MPR)
Ramy czasowe: From enrollment to postoperative pathological assessment after completion of neoadjuvant immunotherapy and radical surgery, approximately 3 to 6 months.
|
The proportion of participants who achieve major pathological response after neoadjuvant immunotherapy.
MPR is defined as residual viable tumor cells of 10% or less in the resected tumor specimen after radical surgery.
|
From enrollment to postoperative pathological assessment after completion of neoadjuvant immunotherapy and radical surgery, approximately 3 to 6 months.

Pathological complete response (pCR)
Ramy czasowe: From enrollment to postoperative pathological assessment after completion of neoadjuvant immunotherapy and radical surgery, approximately 3 to 6 months.
|
The proportion of participants who achieve pathological complete response after neoadjuvant immunotherapy.
pCR is defined as the absence of residual viable tumor cells in the resected primary tumor specimen and, if applicable, resected lymph nodes after radical surgery.
|
From enrollment to postoperative pathological assessment after completion of neoadjuvant immunotherapy and radical surgery, approximately 3 to 6 months.
|
|
R0 Resection Rate
Ramy czasowe: From enrollment to postoperative pathological assessment after radical surgery, approximately 3 to 6 months.
|
The proportion of participants who undergo radical surgery with microscopically margin-negative resection.
R0 resection is defined as no residual tumor at the surgical resection margins based on postoperative pathological assessment.
|
From enrollment to postoperative pathological assessment after radical surgery, approximately 3 to 6 months.
|
|
Event-Free Survival (EFS)
Ramy czasowe: From enrollment to disease progression, recurrence, death, or last follow-up, assessed up to approximately 36 months.
|
EFS is defined as the time from enrollment to the first occurrence of any event, including disease progression that precludes radical surgery, local or distant recurrence, or death from any cause, whichever occurs first.
|
From enrollment to disease progression, recurrence, death, or last follow-up, assessed up to approximately 36 months.
|
|
Recurrence-Free Survival (RFS)
Ramy czasowe: From radical surgery to recurrence, death, or last follow-up, assessed up to approximately 36 months.
|
RFS is defined as the time from radical surgery to the first documented local or distant recurrence, or death from any cause, whichever occurs first.
Participants without recurrence or death will be censored at the date of last follow-up.
|
From radical surgery to recurrence, death, or last follow-up, assessed up to approximately 36 months.
|
|
Overall Survival (OS)
Ramy czasowe: From enrollment to death or last follow-up, assessed up to approximately 30 months.
|
OS is defined as the time from enrollment to death from any cause.
Participants who are alive at the time of analysis will be censored at the date of last follow-up.
|
From enrollment to death or last follow-up, assessed up to approximately 30 months.
