Improving well-being for individuals with persistent pain after surgery for breast cancer, lobular carcinoma in situ, or ductal carcinoma in situ: A randomized clinical trial
Open accessAbstract
>276,000 Americans will be diagnosed with invasive breast cancer, lobular carcinoma in situ, or ductal carcinoma in situ this year and most will undergo breast surgery as part of their care. Although prognosis is excellent, many patients experience persistent post-surgical pain (PSP), which has no satisfactory pharmacological treatment. The causal contributions of pain-associated psychological factors (e.g., catastrophic thoughts about pain, psychological flexibility, self-efficacy) to the continuing burden of PSP have not yet been determined and may be opportune intervention targets. The randomized trial described here will compare the benefits of three manualized behavioral interventions for individuals with PSP. Participants will receive either: 1) self-guided health education (SGHE); 2) interventionist-guided health education (IGHE); or 3) interventionist-guided pain coping skills training with elements of acceptance and commitment therapy that specially target catastrophic thoughts about pain, self-efficacy, and psychological flexibility (CST-PSP). Participants will prospectively complete validated assessments of primary outcomes (PSP severity and interference) at baseline (pre-intervention) and 3-, 6-, and 12-months later. Validated measures of emotional distress and cancer-specific distress will be assessed as secondary outcomes. To test their roles as drivers of PSP, catastrophic thoughts about pain, self-efficacy, and psychological flexibility, will be assessed and statistically analyzed as mediators of hypothesized beneficial effects. The interventions' impacts on pain sensitivity and central sensitization will be investigated to test these physiological pathways as proximal drivers of PSP. To better characterize the patient experience, additional validated measures will be explored for associations with PSP, along with demographic and clinical factors.

Behavioral interventions based on the biopsychosocial theory of pain and targeting psychosocial factors may be especially suitable for reducing persistent post-surgical pain in breast cancer survivors.
“Behavioral intervention strategies that are grounded in the biopsychosocial theory of pain7, and target psychosocial factors thought to contribute to persistent pain in interaction with underlying central neurobiological processing and peripheral afferent inputs6, 8–11, may be especially well suited to ameliorate PSP among breast cancer suvivors6, 8.”

The Introduction supports targeting psychosocial factors within a biopsychosocial approach to persistent pain. The Social/Interpersonal Factors section reports an association between social support and less postoperative pain after breast-cancer surgery, but it does not establish that behavioral interventions are especially suited to reducing persistent postsurgical pain in breast cancer survivors. Page numbers were not available in our copy. (LLM, conf=0.84)

In “The human brain in chronic pain – a general model” (page unavailable), the paper describes chronic pain as involving interplay between brain processes and injury-related sensory input. It does not assess behavioral interventions or establish that they are especially suitable for persistent post-surgical pain in breast cancer survivors. (LLM, conf=0.84)

The section “Reconciling ‘peripheralists’ and ‘centralists’” (page not provided) describes interactions between peripheral inputs and central pain processing and suggests that cognitive interventions may be preferable for some chronic pain conditions.

Breast cancer survivors who catastrophize about pain have greater persistent post-surgical pain in cross-sectional and prospective studies.
“BCSs who experience catastrophic thoughts about their pain have greater PSP in both cross-sectional and prospective studies13–15”
Quote in the paperSubstantial claim1 of 3 sources checked- cites [13] source
The Results report that survivors with persistent breast pain had higher pain catastrophizing than survivors without it, supporting the cross-sectional association. The Introduction says a meta-analysis of prospective studies found no significant downstream effect of psychological factors on persistent breast pain, and the Discussion identifies this paper’s own data as cross-sectional. The prospective-studies portion is therefore not supported. (LLM, conf=0.86)

Psychological flexibility and self-efficacy may contribute to differences in pain severity and the impact of persistent post-surgical pain.
“Two additional psychosocial variables that may contribute to differences in the experience of pain severity and the impact of PSP are: 1) psychological flexibility18–20, a flexible behavior pattern broadly oriented toward ones chosen personal values, even in the presence of discomforts (such as pain), and 2) self-efficacy21–25, the belief in one’s ability to effectively manage pain.”
Quote in the paperSubstantial claim4 of 8 sources checked- cites [18] source
The Introduction links psychological flexibility processes to the severity and impact of chronic pain, and the Results (Mediation analyses) associate changes in those processes with pain intensity and interference. The study concerns adults receiving CBT for chronic pain, not specifically persistent post-surgical pain, so it does not establish that relationship for PSP. The self-efficacy clause has separate citations and is not attributed to this source. (LLM, conf=0.86)

The Pain Interference section (page unavailable) reports that psychological flexibility explained differences in pain interference among people with chronic pain, and the Introduction describes values-oriented behavior despite pain. The study does not establish this relationship specifically for persistent post-surgical pain or show that psychological flexibility explains differences in pain severity.

The citation is attached to the self-efficacy portion of the sentence, not psychological flexibility.

The Self-efficacy and Full sample sections describe exercise-related self-efficacy and its association with well-being in breast cancer survivors.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Claims read under definition version 3 (extract-v3) on 2026-09-28.
Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-09-28.
Cited sources are checked by gpt-6-sol.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
