Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
According to a 2020 systemic review and meta-analysis, prevalence of CPSP/ PPSP following breast cancer surgery ranged from 2% to 78% and pooled prevalence was found to be 35%. Higher prevalence was associated with ALND. Several risk factors have been identified which contribute to the development of PPSP. These include; Preexisting pain, preoperative opioid exposure, genetics, psychological factors such as anxiety, depression or catastrophizing, intensity of acute postoperative pain and nerve injury during surgery.
As a result of nerve injury, damaged and non-damaged nerve fibers start generating action potential spontaneously. These are considered ectopic inputs as they do not arise from peripheral terminals. These inputs lead to the development of central sensitization, which is a state of exaggerated functional response of neurons involved in the pain pathway. This increased sensitization results due to increased membrane excitability, enhanced synaptic efficacy and decreased inhibition.
The aim of the present trial is to investigate the effect of ICBN preservation on chronic/ persistent post surgical pain (CPSP/ PPSP). This will be achieved through a randomized control trial with CPSP/ PPSP as a primary outcome measure. Secondary outcome measures will include Health Related Quality of Life (HRQoL), operating time, lymph node yield, functional status of ipsilateral shoulder, post-operative complications and post-operative use of opioid analgesics.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Intercostobrachial Nerve Preservation Arm
Intercostobrachial nerve preserving axillary lymph node dissection will be carried out. Post-operatively, the patients will be monitored in the post anesthesia care unit (PACU). Acute Post-Operative pain will be controlled using a standardized pain management regimen in accordance with World Health Organization (WHO) analgesia ladder. The patients will be discharged from PACU and admitted to surgical ward once numerical rating score (NRI) is below 4.
Intercostobrachial Nerve Preserving Axillary Lymph Node Dissection
A single standardized technique will be used in all of the patients. For patients undergoing mastectomy, ALND will be carried out using the incision given for mastectomy. A separate incision may be required for patients undergoing breast conservation surgery. Flaps of skin and subcutaneous tissue will be raised and dissection will be carried out till the edge of pectoralis major muscle. Clavipectoral fascia will be opened to gain access to axillary fat and the nodes. These will be removed en block and the intercostobrachial nerve will be completely preserved during this dissection.
All of the surgeons carrying out the intervention would have completed formal training (Fellowship Level) in breast surgery.
Intercostobracial Nerve Sacrifice Arm
Intercostobrachial nerve sacrificing axillary lymph node dissection will be carried out. Post-operatively, the patients will be monitored in the post anesthesia care unit (PACU). Acute Post-Operative pain will be controlled using a standardized pain management regimen in accordance with World Health Organization (WHO) analgesia ladder. The patients will be discharged from PACU and admitted to surgical ward once numerical rating score (NRI) is below 4.
