Safety and Efficacy of Mitomycin C-based HIPEC After srHCC and PM of HCC

Inclusion Criteria: 1. HCC patients have been diagnosed by NCCN clinical practice guidelines in oncology, Hepatobiliary cancers, version 2.2021. 2. ECOG score of 0-2 points; 3. Child-Pugh class A-B liver function only; 4. Consistent with the diagnosis of srHCC: symptoms: acute abdominal pain and peritonitis; blood routine tests: decrease of erythrocyte count; increase of leucocyte count, especially the proportion of neutrophils; radiological features: contrast materials extravasation from lesions confirmed by abdominal contrast enhanced computed tomography or promethean magnetic resonance imaging; intraoperative findings of tumor rupture and postoperative pathology are more confidently conclusive. 5. Consistent with PM of HCC: histological evaluations: biopsy of peritoneal nodules or ascites cytology or postoperative pathological verification; radiological diagnose: early enhancement and late wash-out radiological property of peritoneal nodule or mutual confirmation by two senior radiologists. 6. All of selections have received open or laparoscopic hepatectomy to reach complete macroscopic resection or less than 2.5mm of residual tumor tissue, which is equal to 0 or 1 degree of completeness of cytoreduction. 7. Patients voluntarily participated and signed the informed consent. Exclusion Criteria: 1. Contraindications of HIPEC, such as: extensive intra-abdominal adhesions caused by various reasons; complete intestinal obstruction; severe kidney insufficiency; myelosuppression caused by previous targeted therapy or own blood system disease; severe cardiovascular system disease; infection, especially abdominal infection; bleeding tendency or coagulation dysfunction; the vital signs are unstable; cachexia; 2. Extraperitoneal metastasis; 3. Patients who refuse to accept clinical trials; 4. Those who are deemed unsuitable for inclusion by the researchers.
