Bone Microstructure After Gastrectomy Evaluating by Using HR-pQCT

January 12, 2018 updated by: Kobayashi Shinichiro, Nagasaki University

Chronological Change of Bone Microstructure After Gastrectomy

Osteoporosis after gastrectomy, which is characterized by both the loss of bone mass and the deterioration of bone architecture, is a serious complication in the long course after gastrectomy. The aim of the present study was to evaluate osteoporosis by using high-resolution peripheral quantitative computed tomography (HR-pQCT) in the long course after gastrectomy. In total gastrectomy and distal gastrectomy groups, at least 5 years should have elapsed since gastrectomy.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

The patients after gastrectomy loss appetite and decrease the weight. Total gastrectomy especially cause severe sarcopenia and metabolic change. Osteoporosis after gastrectomy, which is characterized by both the loss of bone mass and the deterioration of bone architecture, is a serious complication in the long course after gastrectomy. The primary tools for assessing volumetric density and bone structure are quantitative computed tomography (QCT) and more recently, high-resolution peripheral quantitative computed tomography (HR-pQCT). However the validation of osteoporosis with HR-pQCT before and after gastrectomy remain elusive. The aim of the present study was to evaluate osteoporosis by using HR-pQCT before and after after endoscopic resection, distal gastrectomy, and total gastrectomy in the patients with gastric cancer.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

60 years to 79 years (Adult, Older Adult)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Comparing bone microstructure in control, DG, and TG groups
Time Frame: 2 years after the treatments
volumetric bone mineral density loss comparing with before the treatments
2 years after the treatments

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Comparing bone microstructure with sarcopenia
Time Frame: Before the treatments and 1 and 2 years after the treatments
Correlation between bone mineral density in HR-pQCT and cross-sectional area of the abdominal psoas major muscle
Before the treatments and 1 and 2 years after the treatments
Comparing bone microstructure with serum biomarkers of osteoporosis
Time Frame: Before the treatments and 1 and 2 years after the treatments
Correlation between bone mineral density in HR-pQCT and biomarkers (25-hydroxyvitaminD, calcium, iPTH, P1NP, ICTP, TRACP5b)
Before the treatments and 1 and 2 years after the treatments
Comparing bone microstructure with dual-energy X-ray absorptiometry
Time Frame: Before the treatments and 1 and 2 years after the treatments
Correlation of bone mineral density between HR-pQCT and DXA
Before the treatments and 1 and 2 years after the treatments
Comparing bone microstructure with quality of life (QOL-C30)
Time Frame: Before the treatments and 1 and 2 years after the treatments
Patients will be asked to complete a short debriefing questionnaire covering questions.(QOL-C30). We compared the average sore about Valid and reliable 30-item questionnaire assessing health related quality of life (6 functional, 9 symptom) before and after treatments. The score about QOL-C30 is evaluated on a four level scale without Global quality of life. Global quality of life is evaluated on a seven level scale.
Before the treatments and 1 and 2 years after the treatments
Comparing bone microstructure with quality of life (BDHQ)
Time Frame: Before the treatments and 1 and 2 years after the treatments
Patients will be asked to complete a short debriefing questionnaire covering questions (BDHQ) B-DHQ is 58-item fixed-portion-type questionnaire The score about BDHQ is evaluated on a seven level scale.
Before the treatments and 1 and 2 years after the treatments
Comparing bone microstructure with quality of life (FRAX)
Time Frame: Before the treatments and 1 and 2 years after the treatments
Patients will be asked to complete a short debriefing questionnaire covering questions (FRAX). FRAX score is 12. FRAX is 12-item fixed-portion-type questionnaire. The score about FRAX is evaluated on a two level scale.
