Study summary

This prospective cohort study aims to evaluate the association between preoperative sarcopenia and postoperative outcomes in patients aged 60 years or older undergoing elective surgery for gastrointestinal cancer. Sarcopenia will be assessed preoperatively using the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) criteria, including muscle strength, muscle mass, and physical performance, together with the Strength, Assistance with walking, Rise from a chair, Climb stairs, and Falls (SARC-F) questionnaire and calf circumference measurement. Participants will be followed for 90 days after surgery. Postoperative complications, length of hospital stay, and 30-day and 90-day mortality will be evaluated.

Read the detailed description

Sarcopenia is characterized by reduced muscle strength, muscle mass, and physical performance and may be associated with unfavorable postoperative outcomes in older patients with cancer. This prospective, single-center observational cohort study will include patients aged 60 years or older who are scheduled to undergo elective surgery for gastrointestinal cancer at Van Training and Research Hospital.

Before surgery, demographic and clinical characteristics, including age, sex, and cancer diagnosis, will be recorded. Sarcopenia will be evaluated according to the EWGSOP2 criteria using measurements of muscle strength, muscle mass, and physical performance. The SARC-F questionnaire and calf circumference measurement will also be performed as part of the preoperative assessment.

Participants will receive standard surgical and perioperative care, and no treatment or intervention will be assigned by the study protocol. Patients will be observed for 90 days after surgery. Outcomes will include postoperative surgical complications, length of hospital stay, 30-day mortality, and 90-day mortality. Postoperative complications of interest will include anastomotic leakage, wound-related complications, oral intake intolerance, and delayed mobilization. The study will compare these outcomes between patients with and without preoperative sarcopenia and assess whether sarcopenia is independently associated with adverse postoperative outcomes.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Groups and cohorts

  • Participants With Preoperative Sarcopenia

    Participants aged 60 years or older undergoing elective surgery for gastrointestinal cancer who are identified as having preoperative sarcopenia according to the EWGSOP2 criteria. Participants will receive standard surgical and perioperative care without any study-assigned intervention.

    Other: Preoperative Sarcopenia Status

  • Participants Without Preoperative Sarcopenia

    Participants aged 60 years or older undergoing elective surgery for gastrointestinal cancer who are not identified as having preoperative sarcopenia according to the EWGSOP2 criteria. Participants will receive standard surgical and perioperative care without any study-assigned intervention.

    Other: Preoperative Sarcopenia Status

Interventions

  • OtherPreoperative Sarcopenia Status

    Preoperative sarcopenia status will be determined according to the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) criteria using assessments of muscle strength, muscle mass, and physical performance. The SARC-F questionnaire and calf circumference measurement will also be performed. No therapeutic intervention will be assigned by the study protocol.

What researchers measure

Primary outcomes

  1. Incidence of postoperative complications

    The number and percentage of participants who experience at least one postoperative complication, including anastomotic leakage, wound-related complications, oral intake intolerance, delayed mobilization, or another surgery-related complication. Complications will be identified through inpatient records and follow-up assessments.

    Time frame: From the date of surgery through 90 days after surgery

Secondary outcomes

  1. Length of hospital stay

    The duration of postoperative hospitalization, calculated in days from the date of surgery to the date of hospital discharge.

    Time frame: From the date of surgery through hospital discharge, an average of 7 days

  2. 30-day all-cause mortality

    The number and percentage of participants who die from any cause within 30 days after surgery.

    Time frame: Within 30 days after surgery

  3. 90-day all-cause mortality

    The number and percentage of participants who die from any cause within 90 days after surgery.

    Time frame: Within 90 days after surgery
