swede_colposcopic_score: Swede Score for Colposcopy

Description

Calculates the Swede Score to grade the severity of cervical lesions during colposcopy. The score sums five colposcopic variables (Acetowhitening, Margins, Vessel patterns, Lesion size, and Iodine staining), each scored from 0 to 2. Higher scores correlate with higher-grade cervical intraepithelial neoplasia (CIN).

Usage

swede_colposcopic_score(acetowhitening, margins, vessels, lesion_size,
                        iodine_staining)

Value

A list containing:

Swede_Score

The calculated total score (Range 0-10).

Interpretation

Diagnostic likelihood (Normal/CIN1, CIN2/3, CIN3/Cancer).

Arguments

acetowhitening

Numeric (0-2). Reaction to acetic acid. 0: Zero or transparent. 1: Faint or translucent. 2: Distinct, opaque white.

margins

Numeric (0-2). Margin/Surface characteristics. 0: Diffuse or irregular edges. 1: Sharp but irregular edges. 2: Sharp/rolled edges or internal borders ("cuffing").

vessels

Numeric (0-2). Vessel patterns. 0: Fine, regular. 1: Absent. 2: Coarse or atypical.

lesion_size

Numeric (0-2). Size of the lesion. 0: < 5 mm. 1: 5 - 15 mm or 2 quadrants. 2: > 15 mm or 3-4 quadrants or endocervical undefined.

iodine_staining

Numeric (0-2). Reaction to Lugol's iodine. 0: Brown (Positive uptake). 1: Faintly yellow or speckled. 2: Distinct mustard yellow (Negative uptake).
