Clinical Classification of Pain in Breast Cancer Survivors

October 9, 2024 updated by: Ismail Saracoglu, Kutahya Health Sciences University

Clinical Classification of Pain in Breast Cancer Survivors: Nociceptive, Neuropathic or Nociplastic Pain

Breast cancer is the most common malignancy in women worldwide according to International Agency for Research on Cancer. Unfortunately, cancer survivors often face long-term symptoms that occur or persist after completion of treatment. In addition to fatigue, pain is the most common persistent symptom after cancer and cancer treatment. The diagnosis and treatment of pain in cancer survivors is not clear for many physicians. A mechanism-based classification of pain in cancer survivors might be a critical step for clinical reasoning, especially for discrimination of different pain types. The primary aim of this study is to determine the prevalence of the predominant type of pain in Turkish breast cancer survivors using a recent published clinical algorithm.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

The convenience sampling will implement for this cross-sectional study. Breast cancer survivors experiencing chronic pain who presented at the Department of Oncology of Kutahya Health Sciences University Evliya Celebi Hospital will screen for eligibility by their physician and were subsequently requested to participate in this study.

Description

Inclusion Criteria:

  • diagnosed with histologically confirmed invasive or non-invasive primary breast cancer
  • completed remission and their primary treatment at least 3 months prior to study participation
  • experienced pain or a sensitive disorder (like numbness, tingling, etc.) anywhere in body for which they stated a minimum score of 3 on a numeric pain rating scale

Exclusion Criteria:

  • patients affected by other chronic disease,
  • severe psychological disorders
  • active metastases

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Numeric Pain Rating Scale
Time Frame: 1 minute
The NPRS was used to assess the participants' pain levels. In the NPRS, patients are asked to verbally rate the severity of their pain on a scale. The scale is composed of 0 (no pain at all) to 10 (worst imaginable pain).
1 minute
Margolis Pain Diagram
Time Frame: 5 minute
The Margolis Pain Diagram, consists of a dorsal and a ventral drawing body, is used to assess the location and distribution of the pain. Participants will ask to point out the place where they experience pain during the preceding 4 weeks for at least 24 hours
5 minute
Central Sensitization Inventory
Time Frame: 10 minute
The Central Sensitization Inventory (CSI) aims to evaluate symptoms thought to be associated with nociplastic pain. The CSI consists 25 items exploring emotional and somatic disorders associated with CS. Each response is scored from 0 to 4, yielding a total score of 0 to 100. A score of 40 or higher on the CSI means the presence of nociplastic pain.
10 minute
Short Form 36
Time Frame: 10 minute
The Short Form-36 (SF-36) is widely used to measurement of health related quality of life (HRQoL) questionnaire. SF-36 is a 36-item generic self-administered instrument consisting of 8 subscales related to various aspects of HRQoL: physical functioning, physical role, bodily pain, general health, vitality, social functioning, emotional role, and mental health. The 8 subscales are scored from 0 to 100, with higher scores indicating better health status.
10 minute

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Quantitative sensory test
Time Frame: 10 minute
Quantitative sensory testing (QST) is a psychophysical method used to quantify somatosensory function in patients. In QST will be used various stimuli static thermal (thermotest), static mechanical ( a painter brush), pinprick (a calibrated pin) and vibration ( a tuning folk). QST will interrogate whether each stimulus is considered a sensory loss (negative sign) or sensory gain (positive sign or hyperalgesia).

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
July 1, 2023

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
