Intraperitoneal hyperthermic perfusion combined with surgery effective for gastric cancer patients with peritoneal seeding.

Fifteen patients with far-advanced gastric cancer were given surgical treatment followed by intraperitoneal hyperthermic perfusion (IPHP) with mitomycin C (MMC) and misonidazole (MIS), a thermosensitizing drug. Immediately after extensive resection of the abdominal tumors, a 2-hour IPHP was performed at the inflow temperature of 44.7 to 48.7 C, using equipment designed for treatment of cancerous peritoneal seeding as a closed circuit, and under hypothermic general anesthesia at 30 to 31 C. In nine of the 15 patients with peritoneal seeding and/or ascites, cancerous ascites was absent after this treatment. In all cases, repeated cytologic examinations of the lavage from Douglas's pouch were negative. The postoperative courses were uneventful except for Patients 1 and 10, in whom slight leakage occurred. All patients were discharged and are in good health at the time of this writing, 7.2 +/- 4.6 months after the treatment. The Case 4 Patient recently died in a traffic accident. In all patients, transient hepatic dysfunction and hypoproteinemia occurred after the operation. This extensive surgery combined with IPHP using MMC and MIS was well tolerated and is a safe antitumor treatment for gastric cancer with peritoneal dissemination. Neurotoxicity due to MIS was nil.

目的研究胃癌术后腹腔热灌注化疗联合静脉化疗的治疗效果。方法140例胃癌根治术后患者随机分为腹腔热灌注组(n=72)和静脉化疗组(n=68)。腹腔热灌注组患者在静脉化疗同时应用腹腔热灌注化疗,观察两组术后并发症、不良反应、术后生存率及腹腔复发率。结果两组在术后并发症及不良反应无显著性差异。术后3、5年生存率腹腔热灌注组和静脉化疗组分别为86.1%、60.2%和58.3%、29.4%(P<0.05);术后3、5年腹腔复发率分别为5.6%、27.8%和20.6%、53%(P<0.05)。结论胃癌术后腹腔热灌注联合静脉化疗可有效控制复发和转移,提高胃癌术后病人的生存率和生存质量。     

Positive results of combined therapy of surgery and intraperitoneal hyperthermic perfusion for far-advanced gastric cancer.

To evaluate the clinical efficacy of intraperitoneal hyperthermic perfusion (IPHP) for far-advanced gastric cancer, particularly with peritoneal seeding, we investigated the survival times of 59 patients who underwent distal subtotal gastrectomy, total gastrectomy, or total gastrectomy combined with concomitant resection of some of the remaining intra-abdominal organs. In all the 30 patients given IPHP, no cancer cells were present posthyperthermically in the lavage from the Douglas pouch. The 30 patients given IPHP lived longer than the 29 patients not given IPHP (p = 0.001), with a 1-year survival rate of 80.4% in the former group compared to 34.2% in the latter. With respect to a comparison of survival time of patients with peritoneal seeding, 7 patients not given IPHP had a 6-month survival rate of 57.1% and did not survive more than 9 months, whereas 20 patients given IPHP had 1- and 2-year survival rates of 78.7% and 45.0%, respectively; here the difference was significant (p = 0.001). The IPHP and control groups without peritoneal metastasis included 10 and 22 patients, respectively, and the 1-year survival rates are 85.4% and 45.3%, respectively. The survival rates of the former exceeded those of the latter, with p = 0.015 by the generalized Wilcoxon test. Thus this combined therapy offers the promise of extended survival for patients with far-advanced gastric cancer.

Abstract：

Objective To study the efficacy and safety of cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) to treat rabbit model of gastric cancer with peritoneal carcinomatosis (PC).Methods VX2 tumor cells were injected into the gastric submucosa of 42 adult male New Zealand rabbits using a laparotomic implantation technique,to construct rabbit model of gastric cancer with PC.The rabbits were randomly divided into three groups:control group (n = 14),CRS group (n = 14),and CRS + HIPEC group (n = 14 ).The rabbits in control group were observed for natural course of disease progression.Treatments were initiated 8 or 9 days after inoculation of tumor cells,including optimal removal of tumor nodules in CRS group,and maximal removal of tumor nodules and heperthermic chemoperfusion in the CRS + HIPEC group with docetaxel (10 mg/rabbit ) and carboplatin (40 mg/rabbit) at 42 ℃ for 30 min.The primary endpoint was overall survival.The secondary endpoints were body weight,biochemistry,major organ functions and serious adverse events.Results The success rates of rabbit PC model were 100% (42/42).The clinicopathological feature of the model was similar to peritoneal carcinomatosis in human.Overall survival was 18-30 days ( median 24 days) in control group,20-40 days ( median 27 days) in CRS group,and 23-55 days ( median 46 days) in CRS plus HIPEC group ( CRS alone group VS control group,P ＞ 0.05;CRS + HIPEC group vs pure CRS group,P ＜ 0.01 ).As compared with CRS only or control groups,HIPEC could extend the overall survival by at least 70%.At the baseline,on the day of surgery and 7 days after surgery,the count of peripheral blood cells,liver and renal functions,and biochemistry parameters were all comparable.Serious adverse events occurred in 0 animal in control group,2 animals in CRS group including 1 animal died of anesthesia overdose and another 1died of postoperative hemorrhage,and 3 animals in CRS + HIPEC group including 1 animal died of anesthesia overdose,and 2 died of diarrhea 23 and 27 days after operation.Conclusion For rabbit model of gastric cancer PC,CRS alone could not bring benefit while CPS + HIPEC with docetaxel and cisplatin could significantly prolong the survival with a acceptable safety.

Lack of efficacy of prophylactic continuous hyperthermic peritoneal perfusion on subsequent peritoneal recurrence and survival in patients with advanced gastric cancer

BACKGROUND: Peritoneal recurrence is a major cause of death in advanced gastric cancer. Although many kinds of chemotherapy intended to prevent peritoneal recurrence of gastric cancer have been evaluated, few have been successful. Few studies have assessed the clinical significance of continuous hyperthermic peritoneal perfusion in peritoneal recurrence. METHODS: From 1992 to 1999, a total of 124 patients with advanced gastric cancer with tumors invading deeper than the serosa but with no peritoneal metastasis underwent potentially curative gastrectomy and were enrolled in this study. Prophylactic continuous hyperthermic peritoneal perfusion (P-CHPP) was performed in 45 patients younger than 65 years old and without comorbidity who gave informed consent. Seventy-nine patients who did not meet the inclusion criteria represented the control group. After reconstruction of the alimentary tract, P-CHPP was carried out for 40 minutes with 150 mg cisplatin, 15 mg mitomycin C, and 150 mg etoposide in 5 to 6 L physiologic saline maintained at 42 degrees C to 43 degrees C. The surgical results, recurrent pattern, and postoperative morbidity were assessed by univariate and multivariate analysis. RESULTS: When compared with patients not undergoing P-CHPP, patients treated by P-CHPP had higher incidences of respiratory failure (73% vs 19%; P <.0001) and renal failure (7% vs 0%; P <.03). Neither 5-year survival (49% vs 56%) nor the patterns of recurrence (peritoneal, hematogenous, and lymphatic) were affected by P-CHPP. CONCLUSIONS: P-CHPP by our methods had no efficacy as prophylactic treatment for peritoneal recurrence induced by gastric cancer. New therapeutic strategies, such as chemosensitivity assessment, are necessary to obtain good therapeutic results with CHPP.

Continuous hyperthermic peritoneal perfusion for the prevention of peritoneal recurrence of gastric cancer: Randomized controlled study

We performed continuous hyperthermic peritoneal perfusion (CHPP) or continuous normothermic peritoneal perfusion (CNPP) combined with cisplatin (CDDP) 300 mg/kg and mitomycin C (MMC) 30 mg/kg in an attempt to prevent peritoneal recurrence after surgery for gastric cancer. Twenty-two patients were treated with perfusion using about 10 liters of saline heated to 41° to 42°C (CHPP group); 18 patients were treated with saline heated to 37° to 38°C (CNPP group); and 18 patients underwent only gastric surgery without perfusion (control group) in a randomized control study. There were two deaths (9%) due to peritoneal recurrence in the CHPP group, four (22%) in the CNPP group, and four (22%) in the control group. The 1-, 2-, and 3-year survival rates were 95%, 89%, and 68%, in the CHPP group; 81%, 75%, and 51%, in the CNPP group; and 43%, 23%, and 23%, in the control group, respectively. There was a significant difference between the three survival curves by the log-rank test (p<0.01). This difference showed that CNPP and CHPP are both effective procedures for preventing peritoneal recurrence. The maximum concentrations in the perfusate of total and free CDDP with 300 mg administration were 12.2 and 10.1 g/ml, respectively, at the end of the perfusion, and the maximum concentrations of total and free CDDP in plasma were 2.1 and 1.0 g/ml, respectively. The maximum concentrations of MMC in perfusate and plasma with 30 mg administration were 1.00 and 0.05 g/ml, respectively, which are intraperitoneally cytotoxic but systemically safe concentrations.

Resumen En pacientes sometidos a cirugía por cáncer gástrico hemos realizado perfusión peritoneal hipertérmica continua (PPHC) o perfusión peritoneal normotérmica continua (PPNC) combinada con cisplatino (CCDP) en dosis de 300 mg/cuerpo y mitomicina C (MMC) en dosis de 30 mg/cuerpo con miras a prevenir la recurrencia peritoneal. Veintidós pacientes fueron tratados con perfusión de alrededor de 10 litros de solución salina calentada a 41–42°C (grupo PPHC); 18 pacientes fueron tratados con solución salina calentada a 37–38°C (grupo PPNC); y 18 pacientes fueron sometidos a cirugía gástrica solamente, sin perfusión, los cuales constituyeron el grupo de control. El estudio fue randomizado. Las muertes por recurrencias peritoneales fueron dos (9%) en el grupo PPHC, cuatro (22%) en el grupo PPNC y cuatro (22%) en el grupo control. Las tasas de sobrevida a uno, dos y tres años fueron 95%, 89% y 68% en el grupo PPHC; 81%, 75% y 51% en el grupo PPNC; y 43%, 23% y 23% en grupo control, respectivamente. Se encontró una diferencia significativa en las tres curvas de sobrevida en la prueba de log-rank (p<0.01). La significativa diferencia hallada entre las tres curvas de sobrevida demuestran que, no sólo la perfusión intraperitoneal combinada con quimioterapia (PPNC) sino también la hipertermia intraperitoneal (PPHC), son procedimientos efectivos para la prevención de la recurrencia peritoneal. Las concentraciones máximas del CCDP total y libre en el líquido de perfusión en el régimen de 300 mg fue 12.2 y 10.1 g/ml al final de la perfusión. Las máximas concentraciones plasmáticas de CDDP total y libre fueron 2.1 y 1.0 g/ml al final de la perfusión. Las concentraciones máximas de MMC en el líquido de perfusión y en el plasma en regímenes por debajo de 30 mg fueron 1.0 y 0.05 g/ml. Tales resultados demuestran concentraciones intraperitoneales citotóxicas pero sistémicamente seguras.

Résumé Nous mettons en place une perfusion intrapéritonéale hyper (PPHC) ou isothermique continue (PPNC), associée à une chimiothérapie combinée (cisplatine (CDDP) à la posologie de 300 mg/Kg et mitomycine C (MMC) à la posologie de 30 mg/Kg) dans le but de prévenir les récidives péritonéales après chirurgie pour cancer gastrique. Dans une étude randomisée, 22 patients ont été traités par perfusions péritonéale avec 10 liters de sérum physiologique chauffé à 41–42°C (PPHC), 18 ont été traités avec du sérum à 37°C (PPNC) et 18 ont été opérés de leur cancer gastrique sans perfusion postopératoire (groupe contrôle (22%)). Les survies à 1, 2 et 3 ans étaient de 95, 89 et 68%, respectivement dans le groupe PPHC, de 81, 75 et 51% dans le groupe PPNC et de 43, 23 et 23% dans le groupe contrôle. Les trois courbes de survie différaient de façon significative (logrank p<0.01). Ces différences montrent que non seulement la perfusion intrapéritonéale associée à la chimiothérapie mais aussi l'hyperthermie intrapéritonéale sont efficaces pour prévenir la récidive péritonéale. après résection gastrique pour cancer. Les concentrations maximales globales et isolées de CDDP étaient de 12.2 et de 10.1 g/ml à la fin de la perfusion. Les concentrations plasmatiques maximales de MMC globales et isolées étaient de 1.00 et de 0.05 g/ml., respectivement. Ces résultats cliniques favorables démontrent que les concentrations obtenues ainsi ne sont pas nocives.

     

Cytoreductive surgery with intraperitoneal hyperthermic chemotherapy for advanced gastric cancer

Peritoneal carcinomatosis is a common and universally fatal sequelae of gastric carcinoma. Treatment of peritoneal carcinomatosis from appendiceal and colorectal sources with intraperitoneal hyperthermic chemotherapy (IPHC) combined with aggressive cytoreductive surgery has been shown to be effective. There are few data on this treatment modality for carcinoma of the stomach. This study evaluates cytoreductive surgery and IPHC with peritoneal carcinomatosis from gastric carcinoma. Thirty-four patients with peritoneal carcinomatosis due to gastric carcinoma underwent gastric resection with cytoreductive surgery followed by IPHC with mitomycin C. A control group consisting of 40 contemporaneous patients, who underwent radical gastrectomy without extended nodal resection, was identified through the tumor registry. Despite more advanced disease in the IPHC group compared to the control group (P < 0.001), overall survival in the two groups was similar. Proportional-hazards regression analysis shows that only resection status is significantly correlated with improved survival (P = 0.0068). Within the IPHC group, patients who underwent an R0/R1 resection had increased survival times (11.2 vs. 3.3 months, P = 0.015) vs. those who underwent R2 resection. The group who had an R0/R1 resection had 1- and 2-year survival rates of 45% and 45% compared to 16% and 8%, respectively, in the R2 group. Cytoreductive surgery and IPHC is a modality with limited potential for the treatment of peritoneal carcinomatosis from gastric carcinoma. Careful patient selection for this procedure is imperative, and patients in whom an R0/R1 resection can be achieved are the best candidates.

Cytoreductive surgery with intraperitoneal hyperthermic chemotherapy for disseminated peritoneal cancer of gastrointestinal origin

No standard effective treatment exists for peritoneal carcinomatosis of gastrointestinal origin. The pharmacokinetic advantage of intraperitoneal chemotherapy and the synergy of heat and certain anticancer agents have prompted researchers to investigate intraperitoneal hyperthermic chemotherapy in treating disseminated peritoneal cancers. We have conducted a large Phase II trial to determine the safety and efficacy of aggressive cytoreductive surgery and intraperitoneal hyperthermic chemotherapy (IPHC) in treating peritoneal carcinomatosis of gastrointestinal origin. Patients with disseminated peritoneal carcinomatosis of gastrointestinal origin with or without malignant ascites were eligible. After aggressive surgical debulking, patients were administered a 2-hour heated (40.5 degrees C) intraperitoneal perfusion with mitomycin C. The major response variable monitored was overall survival. Patients were assessed for toxicity after IPHC administration using the National Cancer Institute Common Toxicity Criteria. Eighty-four patients with peritoneal carcinomatosis of gastrointestinal origin were evaluated for survival and toxicity (colon, n = 38; appendix, n = 22; stomach, n = 19; other gastrointestinal, n = 5). Thirty-nine (46%) patients had malignant ascites at the time of therapy. The operative mortality (30-day) was 6 per cent. Hematologic toxicity was the most common toxicity but was of mild to moderate severity (7 and 4% of patients had grade 3/4 white blood cell or platelet toxicity, respectively). The overall median survival was 14.3 months. The median survival of patients with peritoneal carcinomatosis of appendiceal, colorectal, and gastric origins were 31.1+, 14.6, and 10.1 months, respectively. Significant differences in median survival were seen in patients without and with malignant ascites (27.7 vs 7.6 months; P = 0.0004) and R0/R1 (complete gross tumor resection) versus R2 (gross residual tumor) surgical resection status (28.5+ vs 10.8 months, P = 0.0002). These data suggest that aggressive cytoreductive surgery with IPHC using mitomycin C is safe and effective in treating peritoneal carcinomatosis of gastrointestinal origin. Additional studies and broader applications of this treatment are encouraged.
