- Background: At present, selected patients with resectable colorectal peritoneal metastases (CRC-PM) are increasingly treated with a combination therapy of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). The aim of this study was to investigate the current worldwide practice.Methods: HIPEC experts from 19 countries were invited through the Peritoneal Surface Oncology Group International (PSOGI) to complete an online survey concerning their personal expertise and current hospital and country wide practice.Results: It is estimated that currently more than 3800 patients with CRC-PM (synchronous and metachronous) are annually treated with CRS and HIPEC in 430 centers. Integration of CRS and HIPEC in national guidelines varies, resulting in large treatment disparities between countries. Amongst the experts, there was general agreement on issues related to indication, surgical technique and follow up but less on systemic chemotherapy or proactive strategies.Conclusion: This international survey demonstrates that CRS and HIPEC is now performed on a large scale for CRC-PM patients. Variation in treatment may result in heterogeneity in surgical and oncological outcomes, emphasising the necessity to reach consensus on several issues of this comprehensive procedure. Future initiatives directed at achieving an international consensus statement are needed.

The impact of PRODIGE 7 on the current worldwide practice of CRS-HIPEC for colorectal peritoneal metastases : A web-based survey and 2021 statement by Peritoneal Surface Oncology Group International (PSOGI)

- IntroductionThe PRODIGE 7-trial investigated the additional value of Hyperthermic Intraperitoneal Chemotherapy (HIPEC) to cytoreductive surgery (CRS) for patients with colorectal peritoneal metastases (CPM). The results of PRODIGE 7 were presented at the 2018 ASCO meeting showing that 30 min oxaliplatin-based HIPEC did not improve overall survival. The current study investigated the impact of PRODIGE 7 on the worldwide practice of CRS and HIPEC.Materials and methodsCRS-HIPEC experts from 19 countries were invited through the Peritoneal Surface Oncology Group International (PSOGI) to complete an online survey concerning the current CRS-HIPEC practice in their hospital and country, and were asked to appraise the effect of PRODIGE 7.ResultsThe survey was completed by 18/19 experts. Although their personal opinions of CRS-HIPEC were barely influenced by PRODIGE 7, they reported a substantial impact on daily practice. This included a switch towards Mitomycin-C based HIPEC-regimens and prolongation of HIPEC perfusion time, a reduction in the number of referrals from non-HIPEC centers, a reduction in national consensus, the removal of HIPEC from national guidelines, and a reduced reimbursement rate.ConclusionThe PRODIGE 7 has had a major impact on the practice of CRS-HIPEC for CPM worldwide. HIPEC remains an attractive option with potential for control and eradication of disease and further studies into the optimal HIPEC-regimen are urgently needed. Meanwhile, given the complexity of the treatment of patients with CPM, and the proven benefits of optimal CRS, referral of patients with potentially resectable CPM to expert centers is recommended whilst the precise role of HIPEC is further evaluated.

Distinct subtypes of proprioceptive dorsal root ganglion neurons regulate adaptive proprioception in mice

Journal article (peer-reviewed)abstract
- Proprioceptive neurons (PNs) are essential for the proper execution of all our movements by providing muscle sensory feedback to the central motor network. Here, using deep single cell RNAseq of adult PNs coupled with virus and genetic tracings, we molecularly identify three main types of PNs (Ia, Ib and II) and find that they segregate into eight distinct subgroups. Our data unveil a highly sophisticated organization of PNs into discrete sensory input channels with distinct spatial distribution, innervation patterns and molecular profiles. Altogether, these features contribute to finely regulate proprioception during complex motor behavior. Moreover, while Ib- and II-PN subtypes are specified around birth, Ia-PN subtypes diversify later in life along with increased motor activity. We also show Ia-PNs plasticity following exercise training, suggesting Ia-PNs are important players in adaptive proprioceptive function in adult mice.
