BackgroundSurgery results in chronic pain in 7-80 percent. One of the most studied is chronic post-mastectomy pain. The prevalence was 40-50 percent in studies performed abroad. As this problem has not yet been studied in the Czech Republic, a retrospective prevalence study was performed to asses the extent of the problem and risk factors for development of chronic post-mastectomy pain.Methods And ResultsAfter ethic committee approval an anonymous questionnaire was developed and distributed in various oncology department and patients'organisations. Response rate was 100 percent, 330 questionnaires were processed. Chronic post-mastectomy pain (lasting longer than 3 months after surgery) was described by 69 (20.9 per cent) women. The pain was permanent in 17 and transient in 46 cases, not specified in 6 cases. The pain intensity was predominantly mild or moderate. Risk factors were younger age (below 55-60 years, p=0.0098), less extensive surgery (tumourectomy vs. mastectomy, p=0.0017), intensive post operative pain (p=0.0002) and radiotherapy (p=0.0174). Trend in chemotherapy (p=0.0778) was observed.ConclusionsThe prevalence of chronic post-mastectomy pain was lower in our study comparing to studies in other countries. The reason remains obscure in spite of detailed analysis.
