- Ages 18 years and older
- Women only
- No healthy volunteers
- Adult, Older adult
Study population: According to the existing literature report, 37.9% to 43.3% of cases of low anterior resection are expected to occur. Therefore, assuming that the major LARS incidence rate is 40%, and the number of subjects to estimate the incidence rate estimation precision (half of the 95% confidence interval width) within 10% is 93 patients. Considering the loss or death rate of 13.2% during follow-up within 1 year in our hospital, the number of subjects required is 108.
Who may be able to join
- Those with newly diagnosed ovarian cancer, fallopian tube cancer and primary peritoneal carcinomatosis who plan to undergo cytoreductive surgery and secondary cytoreductive surgery after neoadjuvant chemotherapy.

About this study
Official title: Assessment of Quality of Life After Low Anterior Resection or Visceral Peritoneal Stripping During cytOreDuctive surgerY for Advanced Ovarian Cancer Requiring Tumor Resection on the Rectosigmoid Colon: a Prospective Cohort Study
This study aims to evaluate the incidence of low anterior resection syndrome and quality of life after cytoreductive surgery for advanced ovarian cancer patients.
Read the detailed description
In advanced ovarian cancer, 24-64% of patients require removal of tumors located in the rectum and sigmoid colon. In order to remove the tumor located in the rectum and sigmoid colon, low anterior resection (LAR) is performed to excise the rectum and sigmoid colon. All patients who underwent low anterior resection are at risk of developing low anterior resection syndrome, which presents symptoms such as frequent bowel movements, frequent defecation, and impaired stool control. Therefore, this study aims to evaluate the incidence of low anterior resection syndrome and quality of life after cytoreductive surgery for advanced ovarian cancer patients.
- Being tested
- Cytoreductive surgery
- Medical subject headings

Questions about this trial
What is this clinical trial studying?
An observational study of Ovarian Cancer and Low Anterior Resection Syndrome, run by Seoul National University 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 7 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: looking for participants now, as of the sponsor's last update on 27 Jun 2023. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Soo Jin Park, MD (+82-02-2072-2388, soojin.mdpark@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Frequency of major LARS after surgery (time frame: 12 months after LAR implementation). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05431530, which also lists 17 linked publications.
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 27 Jun 2023.
