Functional results and quality of life for patients with very low rectal cancer undergoing coloanal anastomosis or perineal colostomy with colonic muscular graft.

BACKGROUND: The aim of this study was to compare functional results and quality of life (QoL) of two salvage techniques: coloanal anastomosis (CAA) or perineal reconstruction after abdominoperineal resection for very low rectal cancer. METHODS: Between 1991 and 2001, 50 patients were operated for a very low rectal adenocarcinoma and analyzed after a follow-up greater than one year and because there was no relapse or no treatment, they were included in the analysis. Thirty-eight patients had a CAA, including: straight anastomosis (n=23), J pouch (n=10), coloplasty (n=2) and intersphincteric resection (n=3). Twelve patients underwent a PC. RESULTS: Vaizey's incontinence score was equivalent for the two groups: CAA 12 (0-22) versus PC 11 (8-13). The only differences were more frequent fractioned stools for the CAA group and increased pad soiling for the PC group. Overall QoL scores (QLQ C-30) were equivalent for CAA and PC. CONCLUSIONS: For very low rectal tumors, the choice of surgical technique must be based on oncologic rather than future functional or QoL criteria, because both approaches seem to provide similar results.

[Panniculectomy as first part of colorectal resection for cancer in a morbidly obese patient].

We reported the case of a patient presenting a rectal cancer of the upper part with a BMI at 59 which was previously considered as a contraindication to surgery. To perform the operation we had to make as first step of the procedure a panniculectomy. The technique made possible the rectal resection under good conditions, without blood transfusion. The post-operative course was uneventful except a pulmonary embolism controlled with medical treatment. This procedure is feasible in colorectal surgery.

A phase II study of irinotecan with 5-fluorouracil and leucovorin in patients with pretreated gastroenteropancreatic well-differentiated endocrine carcinomas.

UNLABELLED: Only a few drugs are active in the treatment of well-differentiated endocrine carcinomas (WDEC). We evaluated the combination of the so-called 'de Gramont schedule' and irinotecan in these tumors in a phase II study. METHODS: 20 patients were enrolled in the study. The combination regimen included irinotecan, 180 mg/m(2) on day 1, followed by 200 mg/m(2) folinic acid in a 2-hour infusion, an intravenous 10-min bolus of 400 mg/m(2) 5-fluorouracil (5FU) and finally 600 mg/m(2) 5FU in a 22-hour infusion. Folinic acid and 5FU were repeated on day 2. Clinical, biological and morphological parameters were assessed by CT every 8 weeks. The site of the primary tumor was the pancreas in 10 cases, the lung in 3 cases and other sites in 7 cases. Sixteen patients had previously received chemotherapy, and 6 of them had had two lines of treatment. Six patients had previously been treated with chemoembolization. RESULTS: The median number of cycles administered was 8. Grade 3-4 neutropenia was observed in 8 patients, and 1 patient experienced febrile neutropenia. There was no toxicity-related death. No complete symptomatic response was observed in 7 evaluable patients; 4 patients had an objective biological response. One patient achieved a morphological objective response, stabilization was observed in 15, but progression occurred in 3 patients. Median survival was 15 months. CONCLUSION: The above-mentioned combination of LV5FU2 + irinotecan does not yield major activity in heavily pretreated unresectable metastatic gastroenteropancreatic WDEC, and significant toxicity was observed.

Treatment of synchronous peritoneal carcinomatosis and liver metastases from colorectal cancer.

AIM: To report our experience of peritoneal carcinomatosis (PC) discovered during abdominal exploration in patients with liver metastases (LM). METHODS: Liver resection plus cytoreductive surgery were combined in 24 patients with LM and moderate PC from colorectal origin treated with a curative intent between January 1993 and November 2003. RESULTS: The mean operative time was 357+/-112 min and median blood loss was 719 ml. One postoperative death occurred and postoperative morbidity was 58%. The mean hospital stay was 21.4+/-4.2 days. Three-year overall and disease-free survival rates were respectively 41.5% (confidence interval [CI]: 23-63) and 23.6% (CI: 11-45). Seven patients are disease-free with a mean follow-up of 27.8 months after their last surgery, 3 having a repeated hepatectomy. Three patients developed a peritoneal recurrence and 13 had recurrence in the liver. The only significant prognostic factor was a number of LMs of less than 3 (p < 0.01). CONCLUSION: A combined treatment of LM plus PC is feasible and is beneficial in selected patients presenting three or fewer metastases.

The doxorubicin-streptozotocin combination for the treatment of advanced well-differentiated pancreatic endocrine carcinoma; a judicious option?

Due to their rarity, only few trials have studied the role of the doxorubicin-streptozotocin (DS) combination in advanced well-differentiated pancreatic endocrine carcinomas (AWDPEC). However, the published results are inconsistent. We reviewed all AWDPEC (5-year period, 45 patients) treated in our institution with the DS combination for: objective response rate (ORR), progression-free survival, overall survival (OS) and toxicity. An ORR of 36% (95% Confidence Interval (CI) 22-49) was obtained, with 16 partial responses (PR). The mean duration of PR was of 19.7 months. Two and 3-year OS rates were 50.2 and 24.4%, respectively. Toxicities were mainly digestive (grade > or =3 vomiting, 13%) and haematological (grade > or =3 neutropenia, 24%). Previous systemic chemotherapy and malignant hepatomegaly were associated with a poorer ORR (P=0.033, P=0.016) and OS (P=0.008, P=0.045). Multivariate analysis demonstrated previous chemotherapy as the only independent predictive-factor for survival (P=0.013). In conclusion, our data confirm the sensitivity of AWDPEC to the DS combination, with an ORR of 36% and a remarkable median response duration of 19.7 months, and suggests that it could be considered as a valid option in first-line therapy.

Prognostic factors after surgery of primary resectable gastrointestinal stromal tumours.

AIMS: To analyse the prognostic factors of gastrointestinal stromal tumours (GIST) after a complete resection of the primary tumour. PATIENTS AND METHODS: Fifty-nine patients who underwent a complete initial resection of a GIST were studied. Peritumoral resections (PTR) were compared to segmental organ resections (SOR). Overall survival (OS) and the disease-free survival (DFS) were calculated using the Kaplan-Meier method. RESULTS: Primary sites were: stomach (25), small intestine (22), rectum (7), duodenum (5). Two patients had nodal involvement. The median follow-up was 45 months. Local DFS was significantly better after SOR compared to PTR (median 63 vs. 11 months, respectively, p<0.001). Univariate analysis for OS identified the grade (p=0.005) and size (p=0.02) as prognostic factors. Only a high histologic grade was an independent factor (p=0.02) in the multivariate analysis. Out of 49 patients who relapsed, the first recurrence was local only in 12, local and distant in 10 and distant only in 27; only one had a lymph node failure. Recurrences were accessible to curative surgery in 22 cases. OS of patients submitted to complete resection of their recurrence was significantly better than patients whose recurrence could not be resected (median 52 vs. 12 months, respectively, p<0.001). CONCLUSION: Complete surgery without rupture remains the mainstay of treatment in patients with localized, resectable disease. A peri-tumoral resection confers a high risk of local recurrence and should be avoided. Lymphadenectomy is not systematic. Grade is the main prognostic factor for OS and can be a decision marker for adjuvant treatment with Gleevec.

Randomized phase II study evaluating oxaliplatin alone, oxaliplatin combined with infusional 5-FU, and infusional 5-FU alone in advanced pancreatic carcinoma patients.

BACKGROUND: A randomized phase II, open-label multicenter study evaluating oxaliplatin alone (OXA), infusional 5-fluorouracil alone (5-FU) and an oxaliplatin/infusional 5-FU combination (OXFU) in untreated, advanced pancreatic carcinoma (APC). PATIENTS AND METHODS: Chemotherapy-naïve patients with advanced or metastatic, histologically/cytologically proven pancreatic carcinoma with measurable disease, received OXA [130 mg/m2, 2-h intravenous (i.v.) infusion] alone, OXA combined with 5-FU (1000 mg/m2/day, continuous i.v., days 1-4), or 5-FU alone, every 3 weeks. RESULTS: Sixty-three patients (42 males/21 females) were treated: 17 patients/52 cycles OXA, 31 patients/ 175 cycles OXFU, 15 patients/41 cycles 5-FU, with a median of three, six and two cycles/patient, respectively. Patient characteristics were similar in all arms. Median age was 57 years (range 21-75), and 83% of patients had PS 0-1. Most patients (62%) had moderate to well-differentiated tumors, 90% had metastatic disease, 81% with liver metastases. All responses (three partial responses; WHO) occurred in the OXFU arm (10% response rate). Five of 32 patients evaluable for clinical benefit were responders (OXA, 14%; OXFU, 21%). Median time to progression and overall survival were higher in the combination arm (4.2 and 9.0 months, respectively) than either single-agent arm (OXA, 2.0 and 3.4 months; 5-FU, 1.5 and 2.4 months, respectively). Moderate hematotoxicity without morbidity was seen in all arms. Two OXFU patients had grade 3 oxaliplatin neurosensory toxicity. CONCLUSIONS: With a 10% response rate, median overall survival of 9 months and an encouraging safety profile, the OXFU combination is effective, appears superior to infusional 5-FU and warrants further studies in APC patients.

Combination of folinic acid, 5-fluorouracil bolus and infusion, and cisplatin (LV5FU2-P regimen) in patients with advanced gastric or gastroesophageal junction carcinoma.

BACKGROUND: Combination chemotherapy with continuous 5-fluorouracil (5-FU) and cisplatin in a monthly regimen is one of the standard treatments for advanced gastric carcinoma. This study evaluated the new LV5FU2-P regimen, designed to improve efficacy and tolerance of the 5-FU plus cisplatin combination. PATIENTS AND METHODS: Forty-three patients with advanced or metastatic gastroesophageal junction or gastric carcinoma were prospectively included in the study. They were treated every 14 days with cisplatin 50 mg/m(2) on day 2 plus folinic acid 200 mg/m(2)/day as a 2-h intravenous (i.v.) infusion on days 1 and 2, plus bolus 5-FU 400 mg/m(2)/day on days 1 and 2, plus continuous 5-FU 600 mg/m(2)/day as a 22-h i.v. infusion on days 1 and 2. Ten patients received a simplified regimen (folinic acid 40 mg/m(2) day 1 + bolus 5-FU 400 mg/m(2) day 1 + continuous 5-FU 2400 mg/m(2) on days 1 and 2 with cisplatin 50 mg/m(2) on day 2). RESULTS: All the patients were assessable for response and 42 for toxicity. One patient achieved a complete response and 15 a partial response, for an overall response rate of 37.2% [95% confidence interval (CI) 22.1% to 52.3%]. The median progression-free survival was 7.2 months (95% CI 5.4-10.9) and the overall survival was 13.3 months (95% CI 10.1-16.4). There were no treatment-related deaths. Hematological and gastrointestinal toxicities were the most common severe toxicities. CONCLUSIONS: LV5FU2-P is an active and well tolerated regimen in the treatment of advanced gastroesophageal junction or gastric carcinomas. It warrants evaluation comparatively with other active regimens.

Efficacy of intraperitoneal chemohyperthermia with oxaliplatin in colorectal peritoneal carcinomatosis. Preliminary results in 24 patients.

BACKGROUND: The complete resection of macroscopic colorectal peritoneal carcinomatosis (PC), followed by intraoperative intraperitoneal chemohyperthermia (IPCH) to treat residual microscopic disease, leads to cure in some patients. We report preliminary results on survival in a phase II study using oxaliplatin (LOHP). PATIENTS AND METHODS: Twenty-four patients with macroscopic colorectal PC underwent complete resection of the PC followed by IPCH with LOHP performed in an open abdominal cavity. The dose of LOHP was 460 mg/m(2) in 2 l/m(2), during 30 min at 43 degrees C, at a flow rate of 2 l/min. During the hour preceding IPCH, they received an intravenous administration of 5-fluorouracil (400 mg/m(2)) and leucovorin (20 mg/m(2)). RESULTS: Mean peritoneal tumoral extension (Sugarbaker's Index) was 16.9 +/- 9.5, median operative duration was 490 min and median blood loss was 965 ml. There were two postoperative deaths (8%) by intracerebral hemorrhage, and morbidity rate was 41.6%. Minimal follow-up was 18 months and median follow-up was 27.4 months (range 18.3-49.6). At 1, 2 and 3 years, overall survival rates were 83%, 74% and 65%, and disease-free survival rates were 70%, 50% and 50%, respectively. Only 32% of the 22 postoperative living patients presented a peritoneal recurrence. A peritoneal index >24 influenced survival, with a 17% recurrence rate at 2 years versus 63% when it was <24 (P = 0.005). CONCLUSION: This new modality of treatment, when feasible, gives encouraging preliminary results, with a promising 3-year survival rate of 65%.

[Is sentinel lymph node mapping relevant for colon cancer?: a feasibility study].

BACKGROUND: Sentinel lymph node (sln) technique using blue injection is controversial for colon cancer. The aim of this study was to evaluate the feasibility and interest of sentinel node detection to identify the ultrastaging rate detecting occult nodal micrometastases missed on routine H&E examination. METHODS: During surgery blue dye was injected subserously around the tumor in 30 patients operated for a colon cancer. The first lymph nodes to turn blue were noted as sln. For each sln three examination levels were performed; if no tumor was detected by H&E examination, a cytokeratine immunohistochemistry study was performed. RESULTS: For each case, one or more sln were found (100%). The median number of lymph nodes examined and of sln found was, respectively, 23 (range 10-55) and 2 (1-4). There were 21 pN0 tumors, among which we found two cases (9%) with a micrometastasis and one case of isolated tumor cells detected, resulting in a 14% (3/21) ultrastaging for pTxN0. The sln was positive in five patients out of nine with a N+ disease. CONCLUSIONS: Sln detection was a successful technique when there was no evident lymph node involvement, no primary large lesion or no associated liver metastasis. Focused examination of the sln identified 10-20% of additional ultrastaging disease for staged pT1, 2, 3N0M0 tumor. This may have an important implication for follow-up and adjuvant treatment in future protocols.

Multicentre phase II study and pharmacokinetic analysis of irinotecan in chemotherapy-naïve patients with glioblastoma.

BACKGROUND: To assess the antitumour activity and safety profile of irinotecan and its pharmacokinetic interactions with anticonvulsants in patients with glioblastoma multiforme. PATIENTS AND METHODS: This multicentre phase II and pharmacokinetic study investigated the effects of irinotecan 350 mg/m(2) given as a 90-min infusion every 3 weeks either prior to (group A) or after relapse following radiotherapy (group B) in chemotherapy-naïve patients with glioblastoma. Preferred concomitant medication for seizure prevention was valproic acid. Pharmacokinetic analysis of irinotecan and its main metabolites (SN-38, SN-38-G, APC and NPC) was performed during cycle 1. An independent panel of experts reviewed the activity data. RESULTS: Fifty-two patients (25 patients in group A and 27 patients in group B) received a total of 191 cycles of irinotecan. Forty-six patients (22 patients in group A and 24 patients in group B) were evaluable and externally reviewed for activity. According to external review, one partial response (group B), seven minor responses (three in group A and four in group B), 12 disease stabilisations (seven in group A and five in group B) were observed. This resulted in an overall response rate of only 2.2% (95% confidence interval 0.2% to 6.5%). The median time to tumour progression was 9 weeks in group A and 14.4 weeks in group B. Six-month progression-free survival rates were 26% in group A and 43% in group B. Grade 3-4 toxicities (percentage of patients in groups A and B) consisted of neutropenia (12.5% and 25.9%), diarrhoea (8.3% and 7.4%), asthenia (12.5% and 7.4%) and vomiting (0% and 7.4%). The clearance of irinotecan was 12.4 and 14.4 l/h/m(2) in two patients who received no anticonvulsant. In patients receiving valproic acid, the clearance of irinotecan was 17.2 +/- 4.4 l/h/m(2). CONCLUSIONS: Irinotecan given at the dose of 350 mg/m(2) every 3 weeks has limited clinical activity as a single agent in patients with newly diagnosed and recurrent glioblastoma after radiotherapy. The toxicity profile and plasma disposition of irinotecan and SN-38 were not strongly influenced by anticonvulsant valproic acid therapy. Although the response rate of irinotecan as a single agent was limited, it remains an attractive drug for combination studies in patients with glioblastoma.

Lack of association between HFE gene mutations and hepatocellular carcinoma in patients with cirrhosis.

BACKGROUND: Liver cirrhosis may lead to hepatocellular carcinoma (HCC), regardless of its cause. Genetic and/or environmental factors may modulate the risk of HCC. Mutations in the HFE gene are responsible for genetic haemochromatosis, a condition known to be associated with liver cirrhosis, HCC, or both. It has recently been suggested that the C282Y HFE gene mutation may be more frequent in patients with HCC that have developed in the non-cirrhotic liver than in the general population. Whether or not HFE gene mutations are associated with an increased risk of HCC in patients with cirrhosis is unknown. AIM: To assess the prevalence of HFE gene mutations in cirrhotic patients with and without HCC. PATIENTS AND METHODS: A total of 133 consecutive cirrhotic patients with HCC were prospectively studied for the presence of C282Y and H63D mutations. The control group consisted of 100 cirrhotic patients without HCC. We used restriction enzyme digestion of polymerase chain reaction amplified genomic DNA for determination of HFE genotypes. Iron loading was assessed on non- tumoral liver biopsy samples from 89 patients with HCC and 73 patients without HCC. RESULTS: The prevalence of C282Y heterozygotes was similar in patients with and without HCC (5% v 4%, respectively; p=0.65) and did not differ from that expected in the general population. None of the HCC patients was found to be homozygous for C282Y or H63D, nor compound heterozygous. The prevalence of H63D heterozygotes was similar in patients with and without HCC (31% v 38%, respectively; p=0.25). No relation was detected between HFE genotypes and hepatic iron loading in patients with or without HCC. CONCLUSION: C282Y and H63D mutations do not appear to be associated with an increased risk of HCC in patients with cirrhosis.

[The new chemotherapy of colorectal cancers].

THE SITUATION: With around 35.000 new cases per year and a 40% mortality rate, colorectal cancer is a real problem of health care in France. Chemotherapy for metastatic disease has completely changed during the ten last years with the emergence of promising new drugs such as oxaliplatin and irinotecan. Oral 5-FU prodrugs have also shown an interesting efficacy in this setting. RESULTS: Showed increased response rate, progression free survival with both drugs, and overall survival, only with the irinotecan-based regimen. Moreover, after aggressive first-line chemotherapy, some patients can undergo surgical resection of the metastases, initially considered as unresectable. We still do not know if these aggressive first-line therapies should be proposed to all metastatic patients or only to a selected subgroup. The best strategies remain to be evaluated. IN THE SETTING OF ADJUVANT CHEMOTHERAPY: Of colorectal cancer, a 6-month 5-FU/folinic acid postoperative chemotherapy is actually the standard for the management of patients with positive lymph nodes (stage III). In stage II patients the benefit of such treatment remains controversial. The benefit of using oxaliplatin or irinotecan in association with 5-FU/folinic acid as adjuvant therapy is under investigation. CONCLUSION: In this 21st century, chemotherapy has a major place in the therapeutic management of colorectal cancer patients.

Adjuvant chemotherapy for colon cancer.

Colorectal cancer is one of the most frequent cancers in the world, especially in occidental countries. The primary curative therapy is surgical resection of the tumour. Within the last 15 years, appropriately powered prospective randomized trials have demonstrated that adjuvant post-operative chemotherapy should be the standard treatment for stage III cancers (node-positive disease). 5-Fluorouracil(5FU)/levamisole was used in the early 1990s but has now been replaced by 5FU/leucovorin. The recommended duration of treatment is 6 months. Combining levamisole with 5FU/leucovorin does not improve efficacy. In patients with stage II colon cancer it is still unclear whether adjuvant chemotherapy is effective. In an attempt to define groups of stage II cases that may benefit from adjuvant chemotherapy, considerable efforts have been made to determine molecular genetic factors (tumour-ploidy and mutations or alterations in oncogenes and tumour-suppressor genes). Regional therapy (particularly portal vein infusion) is one of the other therapeutic strategies still considered to be investigational. Current clinical trials are evaluating the role of non-fluorinated pyrimidine agents in an adjuvant setting.

Optimization of 5-fluorouracil (5-FU)/cisplatin combination chemotherapy with a new schedule of leucovorin, 5-FU and cisplatin (LV5FU2-P regimen) in patients with biliary tract carcinoma.

BACKGROUND: Unresectable biliary tract carcinoma (BTC) is associated with a very poor prognosis. To improve efficacy and tolerance of the 5-fluorouracil (5-FU)/cisplatin combination in BTC, we designed a new therapeutic schedule, the LV5FU2-P regimen. PATIENTS AND METHODS: Twenty-nine patients with advanced or metastatic BTC were prospectively enrolled in the study. The treatment (LV5FU2-P regimen) consisted of a biweekly administration of a 2-h infusion of leucovorin 200 mg/m(2), a 400 mg/m(2) bolus of 5-FU followed by a 22-h continuous infusion of 600 mg/m(2) 5-FU on two consecutive days and cisplatin 50 mg/m(2) on day 2. Clinical symptoms, performance and weight changes were monitored. RESULTS: Objective responses were observed in 10 patients (34%) (95% confidence interval 23% to 45%) including one complete response and nine partial responses (stabilization 38%, progression 28%). Median progression-free survival and overall survival were 6.5 and 9.5 months, respectively. Weight gain was observed in 45% of patients and performance status improved in 60%. One patient had a grade 4 thrombocytopenia, and grade 3 toxicity occurred in 41% of patients. There were no treatment-related deaths. CONCLUSIONS: This study, one of the largest phase II trials performed for this disease, shows that the LV5FU2-P regimen is an active and well-tolerated chemotherapy for advanced and metastatic BTC.

Percutaneous radiofrequency ablation of hepatic tumors during temporary venous occlusion.

OBJECTIVE: We evaluated the feasibility, tolerance, and efficacy of percutaneous hepatic vein or segmental portal branch balloon occlusion during radiofrequency ablation of hepatic malignancies. SUBJECTS AND METHODS: Ten tumors were treated by percutaneous radiofrequency ablation during balloon occlusion of a hepatic vein (n = 8) or a segmental portal branch (n = 2). Venous occlusion was undertaken because the tumor was in contact with a hepatic vein (n = 3) or a portal branch (n = 1); because the tumor exceeded 35 mm in width (mean, 44 mm), which was considered the maximum size amenable to ablation in a single session (n = 2); or because of both large size and contact with a hepatic vein (n = 3) or a portal branch (n = 1). RESULTS: Vascular occlusion was always technically possible. Radiofrequency was delivered to one to three locations (mean, 1.9 locations) with a cluster electrode. The largest axis of radiofrequency-induced lesions after ablation with the cluster needle-between 42 and 51 mm (mean, 49 mm)-was always larger than the targeted tumor. These sizes were statistically larger than in a matched control group of patients who underwent radiofrequency ablation without vascular occlusion (p < 0.0003). After a mean follow-up of 12.6 months, CT and MR imaging revealed complete destruction of nine tumors after a single radiofrequency ablation treatment; one tumor required three treatments to achieve ablation. Five patients are tumor-free 12-18 months (mean, 14.4 months) after the first radiofrequency ablation treatment, and five developed new liver metastases. CONCLUSION: Temporary hepatic vein or portal branch occlusion during radiofrequency ablation can safely facilitate the treatment of large tumors or tumors in contact with the walls of large vessels.

Curative treatment of peritoneal carcinomatosis arising from colorectal cancer by complete resection and intraperitoneal chemotherapy.

BACKGROUND: Peritoneal carcinomatosis (PC) is fatal, despite standard systemic chemotherapy. A new approach that combines maximal surgery with maximal regional chemotherapy has potential to cure selected patients who have colorectal PC. The authors have reported the oncologic results of this combined treatment. METHODS: The authors performed a retrospective study of 64 patients who had PC arising from colorectal adenocarcinomas, 19 (29.6%) of whom also had other metastases. These patients were treated by complete resection of all detectable tumors and by a 5-day course of early intraperitoneal chemotherapy (EPIC) with mitomycin C, then by 5-fluorouracil (n = 37), or by intraoperative intraperitoneal chemohyperthermia (IPCH) with mitomycin C, alone or combined with cisplatin (n = 27), in 2 separate trials. In the trial of IPCH, aimed at selecting the most reliable procedure in terms of spatial diffusion and thermal homogeneity, the 27 patients were treated with 7 different procedures. The extent of PC was assessed precisely by using a peritoneal index. The median follow-up period for the entire patient population was 51.7 months. RESULTS: The postoperative mortality and morbidity rates were 9.3% and 54.6%, respectively. Most severe complications occurred in patients who required extensive cytoreductive surgery. Global and disease-free survival rates were respectively 60.1% and 54.7% at 2 years and were 27.4% and 18.4% at 5 years. Results were significantly better (P = 0.04) when patients were metastasis-free (apart from PC) and when the peritoneal index was lower than 16 (P = 0.005). IPCH seemed to be more effective than EPIC for treatment of PC. CONCLUSION: This treatment plan, which combined maximal surgery with maximal regional chemotherapy, cured approximately 25% of patients. This strategy was mainly applicable to patients with limited intraperitoneal cancer volume and no extraperitoneal involvement. IPCH proved to be more effective than EPIC but more difficult to use correctly. Future results should improve through routine use of the optimal hyperthermia procedure, with improvements in the composition of instillate, better patient selection, and the reduction in the rate of complications that occurs with physician experience.
