Peritoneal Cancer

Gastric cancer (GC) is the fourth most common cancer and the second leading cause of cancer death in the world; 53–60% of patients show disease progression and die of peritoneal carcinomatosis (PC). PC of gastric origin has an extremely inauspicious prognosis with a median survival estimate at 1–3 months. Different studies presented contrasting data about survival rates; however, all agreed with the necessity of a complete cytoreduction to improve survival. Hyperthermic intraperitoneal chemotherapy (HIPEC) has an adjuvant role in preventing peritoneal recurrences. A multidisciplinary approach should be empowered: the association of neoadjuvant intraperitoneal and systemic chemotherapy (NIPS), cytoreductive surgery (CRS), HIPEC, and early postoperative intraperitoneal chemotherapy (EPIC) could increase the rate of completeness of cytoreduction (CC) and consequently survival rates, especially in patients with Peritoneal Cancer Index (PCI) ≤6. Neoadjuvant chemotherapy may improve survival also in PC from GC and adjuvant chemotherapy could prevent recurrence. In the last decade an interesting new drug, called Catumaxomab, has been developed in Germany. Two studies showed that this drug seems to improve progression-free survival in patients with GC; however, final results for both studies have still to be published.

PURPOSE Gastric cancer (GC) with peritoneal metastases (PMs) is a poor prognostic evolution. Cytoreductive surgery (CRS) yields promising results, but the impact of hyperthermic intraperitoneal chemotherapy (HIPEC) remains controversial. Here we aimed to compare outcomes between CRS-HIPEC versus CRS alone (CRSa) among patients with PMs from GC. PATIENTS AND METHODS From prospective databases, we identified 277 patients with PMs from GC who were treated with complete CRS with curative intent (no residual nodules > 2.5 mm) at 19 French centers from 1989 to 2014. Of these patients, 180 underwent CRS-HIPEC and 97 CRSa. Tumor burden was assessed using the peritoneal cancer index. A Cox proportional hazards regression model with inverse probability of treatment weighting (IPTW) based on propensity score was used to assess the effect of HIPEC and account for confounding factors. RESULTS After IPTW adjustment, the groups were similar, except that median peritoneal cancer index remained higher in the CRS-HIPEC group (6 v 2; P = .003). CRS-HIPEC improved overall survival (OS) in both crude and IPTW models. Upon IPTW analysis, in CRS-HIPEC and CRSa groups, median OS was 18.8 versus 12.1 months, 3- and 5-year OS rates were 26.21% and 19.87% versus 10.82% and 6.43% (adjusted hazard ratio, 0.60; 95% CI, 0.42 to 0.86; P = .005), and 3- and 5-year recurrence-free survival rates were 20.40% and 17.05% versus 5.87% and 3.76% ( P = .001), respectively; the groups did not differ regarding 90-day mortality (7.4% v 10.1%, respectively; P = .820) or major complication rate (53.7% v 55.3%, respectively; P = .496). CONCLUSION Compared with CRSa, CRS-HIPEC improved OS and recurrence-free survival, without additional morbidity or mortality. When complete CRS is possible, CRS-HIPEC may be considered a valuable therapy for strictly selected patients with limited PMs from GC.

e16280 Background: Hyperthermic intraperitoneal chemotherapy (HIPEC) is the main treatment for peritoneal carcinomatosis (PC).However, It is still a major problem to predict the efficacy of HIPEC. Some studies have shown that peritoneal cancer index (PCI) can be used to predict the efficacy of HIPEC, but the invasiveness and inaccuracy are shortcomings. Therefore, we need a minimally invasive and accurate prediction biomarker. Many studies have confirmed that circulating tumor DNA (ctDNA) can accurately predict the efficacy and prognosis of various solid tumors. This study aimed to evaluate the predictive value of ctDNA from ascites and plasma for HIPEC. Methods: Eligible PC patients should be defintive diagnosed by pathology or cytology. Each patient was treated with HIPEC for 4 times, with an interval of 3 days each time. Plasma and ascites samples were collected before HIPEC and after the last HIPEC. All samples were detected by next generation sequencing (NGS). The molecular tumor burden index (mTBI) and main clone variant allele fraction (VAF) changes were used as the prediction indexes of efficacy. In addition, The changes of common tumor markers such as CEA during the same period were used as controls. Results: A total of 19 patients with PC were enrolled from November 2018 to January 2020. Firstly, the mTBI changes of 14 patients whom had plasma samples at two time points (baseline and postHIPEC)were analyzed. Among them, 3 patients had no gene mutation were detected in two time points. There were significant differences in mTBI before and after HIPEC in the remaining 11 patients (Wilcoxon， p = 0.026). the median Ascites progression free survival (PFS) was 3.35 months (95% CI: 2.34 – 5.13 months), and the median overall survival (OS) was 5.93 months (95% CI: 4.93 – 11.17 months). The mTBI decline was significantly positively correlated with ascites PFS (Spearman r = 0.673, p = 0.023) and moderately positively correlated with OS (Spearman r = 0.510, p = 0.109). The highest VAF in plasma samples was defined as the main clone mutation. The main clone VAF decline was moderately positively correlated with ascites PFS (Spearman r = 0.588, p = 0.057) and slightly positively correlated with OS (Spearman r = 0.386, p = 0.241). As the controls, We found that the common tumor markers decline was no correlated with ascites PFS(Spearman r = 0.091, p = 0.790) and OS (Spearman r = 0.287, p = 0.396). We further analyzed the correlation of VAF between ascites and plasma co-mutation genes in 12 patients. The VAF of co-mutated genes in plasma and ascites was positively correlated (Spearman r = 0.794, p = 0.001). Conclusions: Plasma ctDNA can be used as a biomarker for predicting the efficacy of HIPEC for peritoneal carcinomatosis, and its accuracy is significantly higher than comon tumor markers. However, a larger sample size study are needed to validate our results.

Peritoneal carcinomatosis (PC) has been traditionally considered a terminal disease with median survivals reported in the literature of 6 to 12 months. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) are playing an ever increasing role in the treatment of these patients. Excellent results have been achieved in well-selected patients but there is a very steep learning curve when starting a new program. A program for peritoneal surface malignancies in which patients with PC of gastrointestinal or gynecological origin were treated using multi-modality therapy with combinations of systemic therapy, cytoreductive surgery (CRS), and HIPEC was initiated in December 2007 at “Hospital Regional de Alta Especialidad de Oaxaca,” Mexico. We present the results of our initial experience. From December 2007 to February 2011, 26 patients were treated with CRS and HIPEC. There were 21 female patients. Most common indication (46%) was recurrent ovarian cancer. Mean duration of surgery was 260 minutes. Mean Peritoneal Cancer Index was 9. Twenty-three (88.5%) patients had a complete cytoreduction. Major morbidity and mortality rates were 19.5 and 3.8 per cent, respectively. Mean hospital stay was 8 days. At a mean follow-up of 20 months, median survival has not been reached. Rigorous preoperative workup, strict selection criteria, and mentoring from an experienced cytoreductive surgeon are mandatory and extremely important when starting a center for PC.

Abstract Cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) is a radical but effective treatment option for select peritoneal malignancies. We sought to determine our early experience with this method for peritoneal carcinomatosis secondary to mucinous adenocarcinomas of appendiceal origin. As such, we performed a retrospective clinical study of 30 consecutive patients undergoing CRS with planned HIPEC at the Princess Alexandra Hospital, between June 2009 to December 2012, with mucinous adenocarcinomas of the appendix. CRS was performed in 30 patients, 13 received HIPEC intraoperatively and 17 received early postoperative intra-peritoneal chemotherapy (EPIC) in addition. Mean age was 52.3 years and median hospital stay was 26 days (range 12–190 days). Peritoneal cancer index scores were 0–10 in 6.7% of patients, 11–20 in 20% of patients and >20 in 73.3% of patients. Complete cytoreduction was achieved overall in 21 patients. In total, 106 complications were observed in 28 patients. Ten were grade 3-A, five were grade 3-B and one grade-5 secondary to a fatal PE on day 97. In patients who received HIPEC, there was no difference in disease-free survival (P = 0.098) or overall survival (P = 0.645) between those who received EPIC versus those who did not. This study demonstrates that satisfactory outcomes with regards to morbidity and survival can be achieved with CRS and HIPEC, at a single-centre institution with growing expertise in the technique. Our results are comparable with outcomes previously described in the international literature.

4101 Background: Up to 25% of patients with metastatic CRC present with peritoneal carcinomatosis (PC) as the only site of metastases. The concept of Complete Cytoreductive Surgery (CCRS) followed by Hyperthermia and Intraperitoneal Chemotherapy (HIPEC) was developed, aiming for locoregional disease control and long-term survival. Methods: This prospective multicentre registry included 48 patients (M/F ratio 17/31) with PC from CRC, who underwent CCRS and HIPEC with oxaliplatin(460mg/m2). In 72.9% of patients the primary tumor had been previously resected. Median PCI (peritoneal cancer index) was 11 [1–22], with a median of 6 [1–11] abdominal regions involved and a median lesion size score of 3 [1–3]. In 11 cases associated lymph nodes (63.6% mesenteric, 27.3% para-aortic) were resected. To obtain CCRS a median of 2 [2–6] organs needed to be resected, with anterior resection in 45.8%, total colectomy in 8.3% and small bowel resection in 12.5% of cases. A median of 1 [0–6] anastomosis was performed per patient, of which one third were low and 82.1% were performed after HIPEC. Eleven ileostomies and 5 colostomies were constructed. Results: Median operation time was 460min.[125–840], with a median blood loss of 475ml [2- 6000]. HIPEC posed few procedural problems. There was no postoperative mortality. Complication rate was 52.1%, with 18 intra- and 17 extra-abdominal complications. Anastomotic leakage occurred in 10.4% of patients, bleeding in 6.3% and prolonged ileus in 22.9%. Median hospital stay was 20 [5–65] days. Occurrence of intra-abdominal complications significantly affected hospital stay (p=0.0012), but no risk factors for occurrence of postoperative complications could be clearly identified. Median follow-up was 22.7 [3.2–55.7] months, with 91.7% 2-year overall survival. Progression-free survival at 2 years is 64.6%, with PC recurrence in 29.2% of patients and other metastatic disease in 25%. Multivariate analysis only retained the CEA-level as a significant prognostic factor (p=0.0065). Conclusions: CCRS followed by HIPEC for PC of colorectal origin is safe and has longer than expected PFS and OS. No significant financial relationships to disclose.

Purpose: To compare fluorouracil (FU) alone with FU plus cisplatin (FP) and with uracil and tegafur plus mitomycin (UFTM) for patients with advanced gastric cancer in a prospective, randomized, controlled trial. Patients and Methods: A total of 280 patients with advanced gastric cancer were randomly allocated and analyzed for survival, response, and toxicity. The survival curves were compared between groups by log-rank test on an intent-to-treat basis. Results: At the interim analysis, the UFTM arm showed a significantly inferior survival with higher incidences of hematologic toxic effects than did control arm FU alone, and the registration to UFTM was terminated. Both investigational regimens, FP and UFTM, had a significantly higher incidence of hematologic toxic effects than FU alone, although the effects were manageable. The overall response rates of the FU-alone, FP, and UFTM arms were 11%, 34%, and 9%, respectively. The median progression-free survival was 1.9 months with FU alone, 3.9 months with FP, and 2.4 months with UFTM, respectively. Although FP demonstrated a higher response rate (P < .001) and longer progression-free survival than did FU alone (P < .001), no differences in overall survival were observed between the arms. The median survival times and 1-year survival rates were 7.1 months and 28% with FU, 7.3 months and 29% with FP, and 6.0 months and 16% with UFTM, respectively. Conclusion: Neither investigational regimen, FP nor UFTM, showed a survival advantage as compared with FU alone. FU alone will remain a reference arm in our future trial for advanced gastric cancer.

Background: Gastric cancer (GC) is prone to metastasis that typically resulted in peritoneal carcinomatosis (PC). GC patients with PC have an extremely poor clinic prognosis. Although GC is sensitive to chemotherapy, PC causes chemotherapy failure. Recent studies showed the combination of intravenous and intraperitoneal chemotherapy can significantly improve the survival rates in GC patients with PC. Aim: To identify the clinical and adverse effects of intravenous chemotherapy combined with intraperitoneal perfusion chemotherapy in the treatment of abdominal peritoneal carcinomatosis arising from gastric cancer. Methods: Retrospective analysis was performed on 49 patients with abdominal peritoneal carcinomatosis from gastric cancer who were treated at the Fujian Medical University Union Hospital between September 2010 and September 2015. The patients were divided into 2 groups based on treatment method: patients subjected to intravenous chemotherapy (n = 27), referred to as the simple group and patients subjected to combined intravenous and intraperitoneal chemotherapy (n = 22), referred to as the combination group. The short-term effects and adverse effects were evaluated based on treatment method, in conjunction with a related review of the results. The long-term effect was evaluated based on the survival rate and median survival time of both groups of patients at 12, 18, 24, 30, 36, and 60 months, as determined through follow-up. Results: Gender, age, ECOG scores before treatment, clinical stages, and the pathologic data of advanced GC patients of the 2 groups were equally distributed. The objective efficacy evaluation results showed that the objective response rate (ORR) and disease control rate (DCR) of the simple group after treatment were significantly lower than in the combination group. The median survival time (MST) of the simple group was (6.57 ± 0.75) months, which was significantly shorter than in the combination group (15.03 ± 2.31) months ( P < 0.05). In addition, the 12-, 18-, 24-, 30-, 36-, and 60-month survival rates of the simple group were all significantly lower than those of the combination group. Furthermore, combined therapy improved the physical condition of the patients. The incidence of adverse reactions in the 2 groups was not statistically significant; neither of the treatments resulted in severe complications. Conclusion: Compared with intravenous chemotherapy alone, the combined intravenous and intraperitoneal perfusion chemotherapy was more effective in improving quality of life and extending survival in time patients with abdominal peritoneal carcinomatosis from gastric cancer. In addition, the treatment produced only mild adverse effects, showing that it is tolerable and therefore worth further clinical study.

Gastric cancer (gc) is one of the most common cancers worldwide. The majority of newly diagnosed gastric cancer cases present with distant metastases. Peritoneal carcinomatosis (pc) is the most unfavorable type of progression of primary gc, which occurs in 14–43 % of patients. The purpose of the study was to highlight modern approaches to the treatment of gc with pc. Material and methods. We analyzed 136 publications available from pubmed, medline, cochrane library, and elibrary databases. The final analysis included 46 studies that met the specified parameters. Results. The modern approaches to the treatment of gc with peritoneal carcinomatosis were reviewed, namely: cytoreductive surgery (crs), combination of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (crs/hipec); neoadjuvant intraperitoneal/systemic chemotherapy (nips) and pressurized intraperitoneal aerosol chemotherapy (pipac). The results of large randomized trials and meta-analyses were analyzed. Benefits and limitations of these trials were assessed. Conclusion. The peritoneal cancer index (pci) and the level of cytoreduction are two key prognostic factors for increasing the median overall survival. By reducing tumor volume through cytoreductive surgery, it is possible to allow tumor cells to re-enter the proliferative phase of the cell cycle and make them more sensitive to antitumor agents. The hematoperitoneal barrier is the main reason that prevents the effective delivery of drugs from the systemic bloodstream to the abdominal cavity, which is why the effect of systemic chemotherapy on peritoneal metastases is extremely limited. Intraperitoneal chemotherapy offers a more effective and intensive regional therapy, creating a so-called «depot» of a chemotherapy drug, thereby prolonging the effect of the administered drugs. Cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (crs + hipec) using the combination of surgical resection, cytotoxic chemotherapy, hyperthermic ablation of the tumor and hydrodynamic flushing, is a promising approach in the treatment of gc with peritoneal carcinomatosis.
