About this study

Official title: Lacrimal Drainage Obstruction in Gastric Cancer Patients Receiving Adjuvant S-1 Chemotherapy: A Prospective Study

S-1 is an effective drug in gastric cancer (GC) for palliative chemotherapy in Eastern and Western patients. Recently, S-1 has been also reported to be an effective adjuvant therapy for GC patients who received D2 surgery in Eastern Asian patients.

Recently, the development of lacrimal drainage obstruction (LDO) caused by S-1 has been reported from some case and small-sized studies. The incidence of developing LDO has been estimated to about 15~20% of patients receiving S-1 therapy in some retrospective studies. However, there is no prospective report on the incidence of LDO in patients receiving S-1 chemotherapy. Moreover, the mechanism of developing S-1-induced LDO has not been systemically studied until now. Suggested mechanism of LDO involves direct secretion of S-1 into the tear.

Therefore, this study was initiated to prospectively investigate the incidence of LDO in GC patients receiving adjuvant S-1 chemotherapy. In addition, the correlation between the development of LDO and the concentration of S-1 (or its metabolites) in tear and plasma will be explored. These results will help clinicians identify patients who are at high risk of developing S-1-associated LDO.

Receives: Drug: S-1

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The incidence of LDO

    The cumulative incidence of LDO during the 1 year after adjuvant S1 chemotherapy will be analyzed

    Measured: The incidence of LDO (1 year)

Secondary outcomes (1)
  1. Correlation between the concentration of S-1-related chemical compounds and the developement of LDO

    Correlation between the concentration of S-1-related chemical compounds (5-FU or other components) and the risk of developing LDO will be investigated. Plasma and tear samples will be aquired during the chemotherapy

Questions about this trial

What is this clinical trial studying?

An observational study of Gastric Cancer, run by Seoul National University Bundang Hospital at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 7 Dec 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Keun-Wook Lee, M.D. & Ph.D. (82-31-787-7009, hmodocto@hanmail.net), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The incidence of LDO (time frame: The incidence of LDO (1 year)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Dec 2011.
