Lancet: Study on the risk of recurrence of breast cancer locally or after all hemp

Recently, researchers examined the effects of the use of local anesthesia with vertebral blockagule analgesics and propaeucophenol and the use of volatile anesthetic heptafluoroetheride and opioid analgesics on the risk of persistent incision pain andthe risk of recurrence of breast cancerstudies conducted in Argentina, Austria, China, Germany, Ireland, New Zealand, Singapore and the United States, and patients under the age of 85 who were prepared to undergo primary breast cancer treatment were randomly treated with local anaesthetic-analgesics (vertebral blockand and isopropofol) or whole hemp (heptatric ether) and opioid analgesicsThe main endpoint of the study was localized or metastatic breast cancer recurrence, and the secondary endpoint was 6 to 12 months of incision pain1043 patients received local anaesthetic-analgesics, 1065 patients received full hemp and followed up for 36 monthsLocal anaesthetic-analgesic group 102 patients relapsed (10%), while 111 patients in the whole hemp group relapsed (10%, HR-0.97)52% of patients in the local anaesthetic-analgesic group had incision pain at 6 months, 52% of the whole hemp group and 28% of the patients in the local anaesthetic-analgesic group had incision pain at 12 months, and 27% of the whole hemp group (OR-1.0)The incidence of neurotic chest pain was not significant between the groups for 6 or 12 monthsstudies concluded that there was no significant difference in the risk of breast cancer recurrence compared to total analgesic-analgesia, and no significant difference in frequency and severity of persistent incisions and breast pain
