Is this trial a fit for you?

Likely a good fit

Adults over 18 who underwent curative-intent gastrectomy 1 month to 5 years ago, have no recurrence, and can provide informed consent are the intended participants.

Probably not a fit

Patients within the first 30 days post-op, those with metastatic or other active malignancies, or those unable/unwilling to consent are not expected to benefit from this validation effort.

What this trial studies

This is a prospective, multicenter Spanish project to translate, culturally adapt, and validate the KOQUSS-40 into Spanish (SPQUSS-41). The process includes expert panel review, pre-testing with 20 patients, a pilot with about 85 patients, and a larger validation phase where SPQUSS-41 is administered alongside EORTC QLQ-C30 and QLQ-STO22. A 30-day retest will measure test–retest reliability and psychometric properties will be analyzed across participants enrolled from participating hospitals. The aim is to produce a reliable Spanish questionnaire specific to symptoms and quality-of-life issues after gastrectomy.

Why it matters

Potential benefit: If successful, SPQUSS-41 will give Spanish-speaking clinicians and researchers a validated, surgery-specific tool to better track symptoms and guide post-gastrectomy care and communication.

How similar studies have gone: Related KOQUSS instruments have been used and translated in other settings with acceptable psychometric results, but the SPQUSS-41 is a new Spanish adaptation undergoing formal validation.
