Description

This measure is used to assess the proportion of patients with breast cancer having conservation surgery who receive radiotherapy to the breast.

Note from the National Quality Measures Clearinghouse: This measure is part of the Cancer Quality Performance Indicators (QPIs) collection. For more information, including a complete list of QPI measure sets, please visit the Healthcare Improvement Scotland Web site External Web Site Policy.

Rationale

Trials have demonstrated a significant reduction in local recurrence with the use of radiotherapy after breast conservation (NHS Quality Improvement Scotland, 2008).

Clinical trials of radiotherapy have shown it can produce a reduction in local recurrence would produce an absolute increase in 20-year survival of about 2% to 4% (Clarke et al., 2005; Fisher et al., 2002; Veronesi et al., 2002).

Primary Health Components

Breast cancer; conservation surgery; radiotherapy

Denominator Description

All patients with invasive breast cancer having conservation surgery (see the related "Denominator Inclusions/Exclusions" field)

Numerator Description

Number of patients with invasive breast cancer having conservation surgery receiving radiotherapy to the breast (see the related "Numerator Inclusions/Exclusions" field)

Type of Evidence Supporting the Criterion of Quality for the Measure

  • A clinical practice guideline or other peer-reviewed synthesis of the clinical research evidence
  • A formal consensus procedure, involving experts in relevant clinical, methodological, public health and organizational sciences
  • One or more research studies published in a National Library of Medicine (NLM) indexed, peer-reviewed journal

Additional Information Supporting Need for the Measure

Unspecified

Extent of Measure Testing

The collection of data is piloted on a small number of patient records using a paper data collection form produced by Information Services Division (ISD). The aim is to identify any anomalies or difficulties with data collection prior to full implementation. At least one NHS board in each Regional Cancer Network participates in the pilot.

Prescriptive standard

Prescriptive Standard

Target: 95%

The tolerance within this target accounts for factors of patient choice and fitness for treatment. In addition, it also reflects those patients identified within the PRIME II Breast Cancer Trial where the omission of radiotherapy may be considered given the minimal survival benefit gained (Kunkler et al., 2015).
