POLARS Score of Battersby et al for Predicting Bowel Dysfunction After Restorative Rectal Cancer Resection

Description

Batterby et al reported the POLARS (preoperative LARS) score for evaluating a patient after restorative rectal cancer resection. This can help to identify a patient who may develop the low anterior resection syndrome (LARS). The authors are from the UK and Danish LARS Study Group.

Parameters:

(1) age of the patient in years (from 30 to 80 years)

(2) sex

(3) partial or total mesorectal excision (PME vs TME)

(4) distance (height) of the cancer from the anal verge in cm

(5) stoma

(6) radiotherapy prior to surgery

Parameter	Finding	Points from Nomogram	Coefficients for POLARS
age of the patient		(-1.758 * (age)) + 140.64	-0.2117 * (age)
sex	male	0	0
	female	9.5	-1.014
PME/TME	PME	0	0
	TME	24.4	-1.9655
distance	from 1 to 15	(-7.143 * (cm)) + 107.143	0.6374 * (cm)
stoma	no	0	0
	yes	9.8	0.7817
RT therapy preop	no	0	0
	yes	35.3	3.3049

score from the nomogram =

= SUM(points for all 6 parameters)

equivalent LARS score =

= (0.0919 * (score)) + 16.308

POLARS

= SUM(points for all 6 coefficients) + 44.9561

LARS Score	Severity of LARS
<= 20	none
21 to 29	minor
>= 30	major
