Summary

BACKGROUND and RATIONALE Colorectal cancer, with 49,000 new diagnoses expected in 2019 (27,000 in men and 22,000 in women) represents, in Italy, the third neoplasm in men (14%) and the second in women (12%). Increasing attention has been recently paid to the outcomes of surgical treatment, in terms of patient's anorectal function and quality of life (QoL). Currently, the majority of patients affected by rectal carcinoma undergo a sphincter-sparing surgery, that is, a low anterior rectal resection (LAR).

It is known that about 50% - 90% of patients undergoing LAR will develop at least some degree of bowel dysfunction: for this reason, the definition of "anterior low rectal resection syndrome" (LARS) has been coined to describe this complex functional condition; the LARS usually includes incontinence to gas and/or liquid or solid stools, constipation, urgency, fragmentation and frequent bowel movements; a worsening of QoL has been also observed.

Due to the importance and high prevalence of this condition, but in the absence of a reliable tool for assessing its severity, the so-called "LARS score" has been introduced. The score has already been validated in several languages, even if this important tool has not been validated in Italian language.

AIMS of the STUDY The primary aim of this study will be the validation in Italian language of the LARS score in a population of Italian patients with a previous history of rectal cancer and treated by anterior rectal resection surgery. Moreover, the convergent and discriminatory validity, and the reliability of the score will be also assessed.

STUDY DESIGN The study will be a prospective observational study on patients affected by rectal cancer and treated by anterior rectal resection surgery with total or partial excision of the mesorectum (TME, total mesorectal excision, or PME, partial mesorectal excision) in the period January 2000 - April 2018. Any Unit of the Fondazione Policlinico Universitario "Agostino Gemelli" - IRCCS of Rome that deals with rectal cancer surgery could join the study.

METHODS The validated English version of the LARS questionnaire will be translated into Italian. The translation will be performed by two independent professional translators.

Based on previous validation studies conducted in other Countries, it has been calculated that the sample size will be 200 patients.

Patients will be assessed by administration of the LARS score questionnaire, of a single question on QoL, and of the EORTC-QLQ-C30 questionnaire.

Each Unit could choose to assess the patients in the preferred way (clinical follow-up visit, e-mail, ordinary mail); however, the method of administration of the questionnaire must be specified in the final communication of data to the coordinating Group. Each Unit joining the Study will be provided with an Excel data collection sheet which must then be completed.

A descriptive analysis of the data will be conducted, and the convergent validity, that is the concordance between the LARS score and the QoL, will be investigated. In addition, discriminatory validity, i.e. the ability of the LARS score to distinguish between subgroups of patients, which usually differ in the LARS score, will be assessed. Finally, the test-retest reliability of the LARS score will be examined, so all patients will receive a second LARS questionnaire 1-2 weeks after completing the first and the results of the two tests will be compared.
