If a man is offered a fact which goes against his instincts, he will scrutinize it closely, and unless the evidence is overwhelming, he will refuse to believe it. If, on the other hand, he is offered something which affords a reason for acting in accordance to his instincts, he will accept it even on the slightest evidence. The origin of myths is explained in this way. Bertrand Russell author, mathematician, & philosopher (1872 1970), Nobel Prize Laureate

Intraperitoneal Chemotherapy Outstanding Issues No trial compared with standard chemotherapy with IV carboplatin + IV paclitaxel There are conflicting results on efficacy of IP chemotherapy as first-line therapy. IP is associated with higher toxicity and worsen quality of life compared to IV chemotherapy

Hyperthermic Intraperitoneal Chemotherapy (HIPEC) March 30 - April 2, 2014 Sheraton Sonoma County Petaluma, California Van Driel WJ et al. N Engl J Med 2018
HIPEC: Weaknesses in this trial Due to small number of patients (245) the survival benefit differs by only 15 patients. More unfavourable non-high-grade (mucinous, clear-cell, high-grade endometrioid, carcinosarcoma) tumors in surgery alone group (13 vs. 3). HIPEC resulted in more toxic effects and longer hospitalization Quality of life comparison not reported.
HIPEC: ESMO-ESGO Consensus HIPEC is not the standard of care as first-line treatment HIPEC should be limited to well-designed prospective randomized clinical trials.
HIPEC: ONGOIG TRIALS ClinicalTrials.gov Identifier: NCT03448354 (randomized); Suk-Joon Chang et al.; N=204 March 30 - April 2, 2014 Experimental arm: NAC-IDS-HIPEC Sheraton Sonoma County Under the clinicians' Petaluma, California decision, HIPEC procedures will be performed at the time of IDS. Procedure: HIPEC (paclitaxel 175mg/m2, 90min; open or closed technique) after IDS. IDS is recommended within 4 weeks after the 3rd NAC cycle. HIPEC procedure is allowed only in case of residual disease less than 5mm. No Intervention arm: NAC-IDS Under the clinicians' decision, HIPEC procedures will not be performed at the time of IDS.
