Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Chronic post-mastectomy pain (CPMP) is a significant issue affecting many women after mastectomy. Factors like age, treatment type, and pre-surgery pain can increase the risk of developing this condition. By evaluating these factors, CPMP can be prevented more successfully and treatment strategies can be developed. This study aims to investigate the factors contributing to CPMP and contribute to the existing literature on this important topic.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Chronic post-mastectomy pain (CPMP) is a common condition and is a significant clinical problem with a prevalence reported in the literature of up to 50%. Approximately 10% of patients experience severe pain, which has a significant impact on their quality of life. Since mastectomy is a frequently performed procedure, this syndrome affects a large number of women. Therefore, it is important to better understand the factors associated with the development of persistent pain.

Several theories have been proposed regarding the development of CPMP, including increased peripheral nociceptor sensitivity (primary hyperalgesia) at the site of injury, central neuronal sensitivity (central hyperalgesia) in spinal and supraspinal regions innervating the injured area, and inflammatory changes triggered by the central nervous system. Recommended methods to prevent CPMP include careful dissection, reduction of inflammatory responses, and the use of minimally invasive surgical techniques to prevent peripheral and central neuronal sensitization.

Epidemiological studies-both retrospective and prospective-have identified some of these risk factors, such as younger age, chemotherapy, radiotherapy, and the presence of preoperative pain or severe acute postoperative pain. Unfortunately, there are few studies on this topic, and the literature needs further support.

The hypothesis in this study is that if investigator can identify the factors that increase chronic pain after mastectomy, investigator can take measures against these factors and reduce the development of chronic pain. Therefore, this study aims to identify the factors contributing to chronic pain after mastectomy.
