Postoperative pain pathophysiology and treatment strategies after CRS + HIPEC for peritoneal cancer.

ABSTRACT: BACKGROUND:Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is a treatment choice for peritoneal cancer. However, patients commonly suffer from severe postoperative pain. The pathophysiology of postoperative pain is considered to be from both nociceptive and neuropathic origins. MAIN BODY:The recent advances on the etiology of postoperative pain after CRS + HIPEC treatment were described, and the treatment strategy and outcomes were summarized. CONCLUSION:Conventional analgesics could provide short-term symptomatic relief. Thoracic epidural analgesia combined with opioids administration could be an effective treatment choice. In addition, a transversus abdominis plane block could also be an alternative option, although further studies should be performed.

Project description:Our experience regarding cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) was reviewed in terms of overall survival (OS) and disease-free survival (DFS) in patients with synchronous peritoneal carcinomatosis (SPC) and metachronous peritoneal carcinomatosis (MPC) from gastric cancer (GC).An analysis of prospectively collected data about patients who underwent CRS and HIPEC from July 2011 to July 2016 was carried out. Patients and tumor characteristics were taken into consideration together with pre and post-operative data. The outcomes concerned OS and DFS in both groups.A total of 17 cases were reported. All patients of SPC group underwent neoadjuvant chemotherapy, while all patients of MPC group underwent adjuvant chemotherapy subsequently to surgery of the primary tumor. The mean follow up period was 9 months (SD±9.5). Thirteen patients (76.5%) had SPC and four (23.5%) had MPC. The mean total Peritoneal Cancer Index (PCI) was 8.5 (SD±8.4). The mean PCI was 3.75 (SD±4.9) for SPC group and 16 (SD±9.5) for MPC (P=0.003). HIPEC regimen was cisplatin plus paclitaxel for fourteen patients (82.4%) and cisplatin plus mitomycin-C (MMC) for three patients (17.6%). OS was 16 months and 6 months respectively in patients with SPC and MPC (P=0.189). DFS was 11 months and 2 months respectively in the two groups (P=0.156). Patients with SPC patients and PCI ?12 were significantly different in terms of DFS from SPC with PCI <12 (P=0.001). Overall, twelve patients had postoperative major complications (CTCAE>2), in particular eight (61%) in SPC group while four (100%) in MPC group. Our study showed significantly better DFS for patients aged >60 years (P=0.016).HIPEC and CRS with cisplatin and paclitaxel in patients with PC from GC showed promising results in improving the DFS and the OS, particularly for patients with PCI <12 and for those aged >60. Although a high incidence of complications was revealed, especially in MPC group.
