Metastatic with BRAF (mutBRAF) or KRAS mutation (mutKRAS)Colorectal cancer (mCRC) patients have poor prognosis after liver or lung surgery, while the prognostic role of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with peritoneal metastases (PM) is unclear
.
Therefore, a team from Norway carried out a related study, and the relevant results were published in the British Journal of Cancer
Metastatic with BRAF (mutBRAF) or KRAS mutation (mutKRAS)Colorectal cancer (mCRC) patients have poor prognosis after liver or lung surgery, while the prognostic role of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with peritoneal metastases (PM) is unclear
The study included 257 patients, of whom 180 received CRS-HIPEC and 77 received only palliative surgery
.
Among the 174 patients who underwent molecular testing of CRS-HIPEC, mutKRAS (n=59, 33.
The study included 257 patients, of whom 180 received CRS-HIPEC and 77 received only palliative surgery
The median survival time after CRS-HIPEC was 49 months, compared with 15 months in the palliative care group (P<0.
001), and the 5-year survival rate was 40.

.
The median DFS after CRS-HIPEC was 11 months
The median survival time after CRS-HIPEC was 49 months, compared with 15 months in the palliative care group (P<0.
There were no significant differences in OS and DFS after CRS-HIPEC when stratified for mutKRAS, mutBRAF or dual wt
.
However, CRS-HIPEC patients with mutBRAF and MSS had a shorter median OS (42 months) than mutBRAF and MSI patients, corresponding to a 5-year OS rate of 25.
There were no significant differences in OS and DFS after CRS-HIPEC when stratified for mutKRAS, mutBRAF or dual wt
There was no correlation between mutation status and type of recurrence
.
In multivariate analysis, PCI (peritoneal tumor index, HR 1.
There was no correlation between mutation status and type of recurrence
In conclusion, the study showed that the proportion of mutBRAF in PM-CRC patients undergoing CRS-HIPEC was higher (24.
7%)
.
Survival was similar in patients with mutBRAF, mutKRAS, and double wild-type, whereas survival was better in patients with mutBRAF and MSI
.
CRS-HIPEC should be considered for patients with mutBRAF tumors and localized PM
