About this study

The primary objectives are to evaluate the prevalence of LARS and Quality of Life in rectal cancer patients 3 years after anterior resection, to investigate if anastomotic technique is a risk factor for major LARS and to study the prevalence of colostomy 3 years after anterior resection and evaluate stoma function according to the stoma scale in EORTC QLQ-CR29.

Read the detailed description

All patients who have undergone anterior resection for rectal cancer between Q1 2015 and Q4 2017 have been identified in the Swedish Colorectal Cancer Registry (SCRCR). Three years after surgery the patients were sent a questionnaire including the LARS (Low Anterior Resection Syndrome)-score, the quality of life questionnaire EORTC QLQ 30 and CR29 in addition to a questionnaire regarding prevalence of remaining stoma.The patient cohort will be divided into two groups operated with total (TME) or partial (PME) mesorectal excision for further analyses. Patients with a stoma will be analysed separately.

Prevalence of major LARS and Quality of Life, QoL, 3 years after anterior resection will be assessed by the EORTC QLQ-C30 and by calculation of LARS Score with categories "no" (0-20 points), "minor" (21-29) and "major" (30-42). The LARS score will be dichotomized into the categories no/minor and major LARS.

Stoma function will be evaluated by the stoma scale in EORTC QLQ-CR29.

What is being measured

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

  1. Low Anterior Resection Syndrome score ( LARS Score)

    Prevalence of low anterior resection syndrome (LARS) 3 years after low anterior resection for rectal cancer, assessed by the validated instrument LARS score consisting of 5 questions with a total score of between 4 and 42. .0-20 corresponds to no LARS, 21-29 to minor LARS and 30-42 to major LARS.

    Measured: 3 years

  2. QoL

    Quality of life measured by the validated EORTC (European Organisation for Research and Treatment of Cancer) questionnaires QLQ 30 (Quality of life questionnaire 30) consisting of 30 questions and CR 29 (colirecti 29), a specific questionnaire assessing quality of life in colorectal cancer patients, consisting of 29 questions. Both QLQ 30 and CR 29 include symptom scales and functional scales from 0-100 with lower scores on symptom scales indicating better quality of life and higher scores on functional scales indicating better quality of life.

    Measured: 3 years

Secondary outcomes (1)
  1. Correlation LARS score QoL

    Correlation between low anterior resection syndrome (LARS) assessed by the validated instrument LARS score consisting of 5 questions with a total score of between 4 and 42, 0-20 corresponding to no LARS, 21-29 to minor LARS and 30-42 to major LARS, and the bowel dysfunction scale in EORTC (European Organisation for Research and Treatment of Cancer) questionnaire CR29 (colirecti 29) consisting of 6 questions with a total score between 6 and 24 with higher score indicating worse function.

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

An observational study of Low Anterior Resection Syndrome and Rectal Cancer, run by Region Skane at 1 site in Sweden.

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 2 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: finished, as of the sponsor's last update on 18 Feb 2021. 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 Sweden. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Low Anterior Resection Syndrome score ( LARS Score) (time frame: 3 years). The study lists 2 primary outcomes in all. 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 18 Feb 2021.
