Cancer pain is a serious problem in the palliative population. In particular, pain due to compression or invasion of nerve tissue by metastasis is frequent and often unresponsive to oral drug therapy and even to epidural administration of opioids. In such refractory pain in a palliative setting, one modality that could be helpful is the use of technics of locoregional analgesia. Currently, they are routinely used for the management of acute postoperative pain and become to be more widely used for cancer surgery. For example, intrapleural intercostal nerve blocks after major lung resection or preincisional paravertebral blocks after breast surgery have been shown to improve pain control. However, locoregional analgesia is only occasionally used in chronic cancer pain.
