Summary

Surgery is first-line treatment for solid tumors. However, surgical trauma-induced physiologic stress has been demonstrated to facilitate metastasis and recurrence in different types of cancer. It has been reported that the PD-1/PD-L1 pathway could be activated by surgical stress. Hence, we instigate the effect of anesthetic technique on expression of PD1 and PD1 ligand.

Conditions

  • Programmed Cell Death 1

Interventions

PROCEDURE

Thoracic Paravertebral block

TPVB will be given using high frequency linear U/S transducer, place the U/S ultrasound probe was placed parallel to the vertebral spine at T4, and, T6 level and shifted 2-3 cm laterally to obtain the appropriate visualization. Following the identification of pleura, transverse process and paravertebral space, the needle was inserted in caudocranial direction using in-plane approach. Confirm negative vessel or pleural breach via aspiration then proceed with local anaesthetic 0.25% bupivacaine (20 ml) delivery slowly divided equally at T4and T6; the pleura will be seen to be pushed downward
