RESUMEN
Peritoneal metastasis is a common finding in patients with advanced gastric cancer. Beyond systemic chemotherapy, additive local treatments such as cytoreductive surgery and intraperitoneal chemotherapy are considered an inherent part of different multimodal treatment concepts for selected patients with peritoneal metastatic gastric cancer. This review article discusses the role of cytoreductive surgery (CRS) and intraperitoneal chemotherapy, including HIPEC, NIPS, and PIPAC, as additive therapeutic options with curative and palliative intent.

BACKGROUND/AIM: The aim of this study was to describe and evaluate the patterns, perioperative outcomes, and survival rates of patients subjected to hepatic resections for ovarian-derived liver metastasis as part of cytoreductive surgery with or without hyperthermic intraperitoneal chemotherapy (HIPEC). Furthermore, we investigated two subgroups of tumor patterns: hematogenous liver metastasis and infiltrative liver metastatic spread. PATIENTS AND METHODS: A retrospective study was conducted. Patients from a University Tertiary Hepatic and Peritoneal Surface Malignancy Center with primary or recurrent ovarian cancer, who underwent liver resection as part of cytoreductive surgery between January 1992 and December 2022, were included. RESULTS: Data from 35 patients were analyzed. Both median overall survival (OS) and disease-specific survival (DSS) were 24.97 months. In a multivariate setting, the combined effect of age, peritoneal carcinomatosis index, body mass index, hematogenous liver metastasis vs. infiltrative spread types, and HIPEC (HR=0.2372; 95%CI=0.0719-0.7823; p=0.0181) over OS was tested. Survival analysis revealed no differences between the two metastatic spread types (OS: p=0.9720; DSS: p=0.9610). Younger age (p=0.0301), splenectomy (p=0.0320), lesser omentectomy (p=0.0178), and right upper quadrant peritonectomy (p=0.0373) were more characteristic for those patients with infiltrative liver metastatic spread. CONCLUSION: Complete cytoreductive surgery, including hepatic resection is a feasible approach with or without additional HIPEC, which may provide survival benefit for patients with advanced and/or recurrent ovarian cancer. If metastatic and infiltrative liver involvement is suspected, liver-specific imaging is recommended.

BACKGROUND: Advanced gastric cancer with synchronous peritoneal metastases (GC-PM) is associated with a poor prognosis. Although cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is a promising approach, only a limited number of Western studies exist. AIM: To investigate the clinicopathological outcomes of patients who underwent CRS-HIPEC for GC-PM. METHODS: A retrospective analysis of patients with GC-PM was conducted. All patients were seen at the Department of General and Visceral Surgery, Hospital Barmherzige Brüder, Regensburg, Germany between January 2011 and July 2021 and underwent CRS-HIPEC. Preoperative laboratory results, the use of neoadjuvant trastuzumab, and the details of CRS-HIPEC, including peritoneal carcinomatosis index, completeness of cytoreduction, and surgical procedures were recorded. Disease-specific (DSS), and overall survival (OS) of patients were calculated. RESULTS: A total of 73 patients were included in the study. Patients treated with neoadjuvant trastuzumab (n = 5) showed longer DSS (P = 0.0482). Higher white blood cell counts (DSS: P = 0.0433) and carcinoembryonic antigen levels (OS and DSS: P < 0.01), and lower hemoglobin (OS and DSS: P < 0.05) and serum total protein (OS: P = 0.0368) levels were associated with shorter survival. Longer HIPEC duration was associated with more advantageous median survival times [60-min (n = 59): 12.86 mo; 90-min (n = 14): 27.30 mo], but without statistical difference. To obtain additional data from this observation, further separation of the study population was performed. First, propensity score-matched patient pairs (n = 14 in each group) were created. Statistically different DSS was found between patient pairs (hazard ratio = 0.2843; 95% confidence interval: 0.1119-0.7222; P = 0.0082). Second, those patients who were treated with trastuzumab and/or had human epidermal growth factor receptor 2 positivity (median survival: 12.68 mo vs 24.02 mo), or had to undergo the procedure before 2016 (median survival: 12.68 mo vs 27.30 mo; P = 0.0493) were removed from the original study population. CONCLUSION: Based on our experience, CRS-HIPEC is a safe and secure method to improve the survival of advanced GC-PM patients. Prolonged HIPEC duration may serve as a good therapy for these patients.

INTRODUCTION: Primary treatment for peritoneal dissemination of appendiceal cancer is the combination of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. The endpoints were overall survival and evaluation of prognostic factors. METHODS: Clinicopathological and treatment-related factors were obtained from a prospective database. A total of 84 patients, 55 (65%) primary and 29 (35%) recurrent malignant appendiceal carcinomas with synchronous and metachronous peritoneal metastases, underwent multimodal treatment between 2011 and 2021. The endpoints of the study were overall survival and evaluation of prognostic factors. RESULTS: The median follow-up was 4.8 y; the mean age was 54.5 y (range 25-77), with a sex distribution of 69% female and 31% male. The mean peritoneal cancer index was 11.3. The proportion of mucinous, intestinal-type, signet ring cell, and goblet cell carcinoma was 56%, 23%, 11%, and 10%, respectively. The 5-y survival rate of the whole cohort was 56.7%. In primary and recurrent diseases, the overall median survival was 8.4 and 4.9 y. Significantly improved survival was detected after complete cytoreduction resection (hazard ratio [HR] for CCR-2 versus CCR-0: 9.388, 95% confidence interval [CI] 3.026-29.124, P = 0.001) and initial local operation with undelayed admission to the center (HR 0.262, 95% CI 0.089-0.773; P = 0.015). The five independent factors in Kaplan-Meier analysis and univariable Cox regression analysis associated with significant adverse survival were cancer antigen (CA) 19-9 over 37 IU/mL, signet ring cell and intestinal-type histology, positive nodal status, grading, and peritoneal cancer index >20. Neoadjuvant chemotherapy administration did not impact survival (HR 1.220, 95% CI 0.612-2.432, P = 0.571). CONCLUSIONS: With multimodal treatment, prolonged survival is attainable in stage IV primary and recurrent appendiceal carcinoma with peritoneal dissemination. Direct referral to specialized centers after confirmation of peritoneal metastasis is recommended because prompt definitive treatment may significantly improve survival.

AIM: This single-centre study evaluated cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) for patients with rare histologies and uncommon tumour origins. PATIENTS AND METHODS: Prospectively collected data from the data registry of a single institution was retrospectively investigated. We present a series of selected patients who underwent CRS and HIPEC between 2011 and 2021 for peritoneal metastases arising from infrequent tumour entities. RESULTS: The study included 76 patients. From the wide range of histologies, seven groups were formed: Cancer of unknown primary, uncommon ovarian cancer types, other gynaecological tumours (endosalpingiosis, endometrial and cervical cancer), small bowel carcinoma, recurrent peritoneal mesothelioma, desmoplastic small round-cell tumour, and other rare malignancies. The median peritoneal cancer index was 8. Fifty-five patients with primary and 22 patients with recurrent disease were examined. Complete macroscopic tumour resection was achieved in 84% of cases. The median survival was 68.53 months considering the entire cohort, whilst the longest survival rate was registered in the group with rare ovarian cancer, and the shortest in the group of patients with small round-cell tumour, at 112.3 and 11.4 months, respectively (small round-cell tumour versus rare ovarian cancer, hazard ratio=15.6817; 95% confidence interval=2.6585-92.5030; p=0.0024). CONCLUSION: Based on the encouraging results in some test groups, especially in rare ovarian cancer, CUP, small bowel cancer and recurrent mesothelioma, multicenter prospective studies examining such rare tumour histologies are needed to reach a higher number of cases and, thus, explore the impact of multimodal therapy on these patients.

PURPOSE: This single-center study evaluated cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) for diffuse malignant peritoneal mesothelioma (DMPM). METHODS: Prospectively collected data from a single institution data registry was retrospectively investigated. Eighty-four patients with primary malignant peritoneal mesothelioma underwent CRS and HIPEC with cisplatin and doxorubicin either for 60 min or 90 min of duration from 2011 to 2021. The primary endpoint was overall survival. The secondary endpoint was the evaluation of prognostic factors for overall survival. The tertiary endpoint was to assess the effect of neoadjuvant chemotherapy on survival. RESULTS: The median follow-up was 5.0 years (95%-CI 4.6-5.5). The median age was 59.2 years (IQR: 47-66). Eighty-two patients (97.6%) had epithelioid tumors. The median peritoneal cancer index was 18.0 (IQR: 13-27). Sixty-six patients (78.6%) had complete or near-complete cytoreduction (CCR 0 or CCR 1). Seventy patients (83.3%) received HIPEC for 60 min and 14 patients (16.7%) received it for 90 min. Twenty-two patients (26.2%) had grade 3 to 4 complications. Acute kidney injury (AKI) stage I-III occurred in 30 (35.7%) patients. Three patients (3.6%) died perioperatively. The overall median survival was 38.4 months (95%-CI 23.6-54.3), and the 5-year survival rate was 42%. Survival was independently associated with age, female gender, and thrombocytosis. Preoperative chemotherapy did not emerge as an adverse prognostic factor. CONCLUSION: In well-selected patients with DMPM, prolonged survival is achievable with CRS and HIPEC in specialized centers.

BACKGROUND/AIM: The aim of the study was to assess diagnostic tools implemented in selecting candidates for cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) with special emphasis on diagnostic laparoscopy. PATIENTS AND METHODS: A total of 229 patients underwent laparoscopy between January 2011 and December 2015 with peritoneal carcinomatosis and were analyzed retrospectively to study the role of laparoscopy in selecting patients for CRS and HIPEC. RESULTS: After initial laparoscopy, 101 (44%) of patients underwent CRS and HIPEC with 128 (56%) being aborted. The most prevalent overall exclusion criterion was extensive small bowel disease with a prevalence of 107 (47%) patients. The rate of complete cytoreduction (CCR0 and CCR1) in patients who were deemed initially operable during laparoscopy was 96%. The most prevalent primary tumor site was the stomach with a prevalence of 36,7%. The overall median peritoneal cancer index (PCI) score of the excluded patients were 16.8 and 4.6 in the CRS and HIPEC group. Port-site metastasis was 3.1% and bowel perforation rate 3.0%. CONCLUSION: Laparoscopy is a proper selection tool in patients with peritoneal metastases for multimodal treatment. Sensitivity for detecting non-resectable patients is high and the morbidity and mortality low.
