简要总结
neuropathic pain can occur following any surgical procedure on the breast ..
详细描述
chronic pain affects the daily lives of post-surgical breast cancer patients. many of these patients were undertreated for pain and generally obtained poor pain relief.treated patients with chronic thoracic segmental pain including patients with post-mastectomy pain syndrome by radiofrequency for dorsal root ganglion reported longterm pain relief.

结局指标
主要结局
The intensity of pain
时间窗: 1 month , 2 month and 3 month post-procedure
A Visual Analogue Scale is a measurement instrument that tries to measure a characteristic or attitude that is believed to range across a continuum of values and cannot easily be directly measured. For example, the intensity of pain. Operationally a VAS is usually a horizontal line, 100 mm in length, anchored by word descriptors at each end. The patient marks on the line the point that they feel represents their perception of their current state.The VAS score is determined by measuring in millimetres from the left handend of the line to the point that the patient marks. Scoring and interpretation : using a ruler, score is determined by measuring the distance(mm) on the10 cm line between the "no pain" anchor and the patient's mark ,providing a range of scores from (0_100). A higher score indicates greater pain intensity. the following cut points on the pain VAS have been recommended: no pain (0-4 mm), mild pain(5-44 mm), moderate pain (45-74 mm), and severe pain (75-100 mm) .
