Abstract
BACKGROUND There is no standard treatment for peritoneal dissemination from gastric cancer. A novel treatment consisting of peritonectomy and intraoperative chemohyperthermic peritoneal perfusion (CHPP) was compared with conventional surgery and CHPP. METHODS Records of all patients who underwent CHPP after cytoreductive surgery between 1992 and 2002 were reviewed. RESULTS Data for 107 patients with peritoneal dissemination were available. Complete cytoreduction was achieved in 47 (43.9 per cent) of the 107 patients: 18 of 65 who underwent conventional surgery and 29 of 42 who had peritonectomy. Twenty-three patients (21.5 per cent) suffered from complications. The overall operative mortality rate was 2.8 per cent. Seventeen patients (15.9 per cent) were disease free and 87 subsequent deaths were related to disease progression. The median survival for all patients was 11.5 months, with a 5-year survival rate of 6.7 per cent. Median survival after complete cytoreduction was 15.5 months and that after incomplete cytoreduction was 7.9 months, with 5-year survival rates of 13 and 2 per cent respectively. Completeness of cytoreduction and peritonectomy were independent prognostic factors. The 5-year survival rate after complete cytoreduction by peritonectomy with CHPP was 27 per cent. CONCLUSION Complete cytoreduction after peritonectomy and CHPP may improve the survival of patients with peritoneal dissemination from gastric cancer.

Abstract
BACKGROUND The peritoneal spread of cancer is a well-known entity carrying a dismal prognosis. A new therapeutic approach is the combination of cytoreduction with heated intraperitoneal chemotherapy (HIPC). The risk of an intra-abdominal anastomosis in the presence of such chemotherapy is recognized clinically but the experimental data on the subject are lacking. The aim of this study is to examine the influence of chemotherapy and hyperthermia on the healing of colonic anastomosis. MATERIALS AND METHODS Colonic anastomosis were performed in four groups of male Wistar rats: (1) control (operation only), (2) HIPC with saline, (3) with mitomycin C (MMC), and (4) with cisplatinum. HIPC was performed using a closed circulation system at 40 degrees C over 20 min. Anastomotic strength was tested on day 4, 7, 10, and 21. RESULTS The bursting pressure of anastomoses in rats treated by HIPC was significantly lower than in controls. On day 4, it was 54.8 mm Hg, 38 mm Hg, 18 mm Hg, and 14.8 mm Hg in groups 1-4, respectively, while on day 7 it was 170 mm Hg, 188 mm Hg, 83 mm Hg, and 19 mm Hg, respectively (P < 0.01). The difference decreased on day 10 and almost vanished on day 21. HIPC with cisplatinum had the worst effect on anastomotic healing during the early postoperative period. CONCLUSIONS Cytoreduction and HIPC are gaining popularity. However, the use of heated chemotherapy has a detrimental effect on the strength of colonic anastomosis, especially during the early postoperative period (until day 10). This may cause anastomotic failure and postoperative morbidity. Therefore, careful selection and avoidance of unnecessary anastomoses are mandatory.

Abstract
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.

Abstract
BACKGROUND A sensitive method for detecting minimal residual disease in the peritoneal cavity by quantifying carcinoembryonic antigen (CEA) mRNA using real-time quantitative reverse transcription-polymerase chain reaction (RQ-RT-PCR) was developed. The clinical value of the method for predicting peritoneal recurrence in patients with gastric cancer was evaluated. METHOD A total of 195 patients with gastric cancer and 20 with asymptomatic cholecystolithiasis were included in the study. CEA mRNA expression in peritoneal washings (p-CEA mRNA) was measured by RQ-RT-PCR and normalized to glyceraldehyde-3-phosphate dehydrogenase mRNA expression. The cut-off level of p-CEA mRNA for gastric cancer was determined by examining p-CEA mRNA levels in patients with asymptomatic cholecystolithiasis. RESULTS Fifty-five (28.2 per cent) of the 195 patients were p-CEA mRNA positive. The rate of p-CEA mRNA positivity correlated significantly with clinicopathological factors. In 163 patients who underwent curative surgery, overall survival and disease-free survival were significantly poorer in p-CEA mRNA-positive patients than in p-CEA mRNA-negative patients (P < 0.001). Cox regression analysis revealed that only p-CEA mRNA was a significant independent prognostic factor (P = 0.034). Multivariate logistic regression analysis showed that p-CEA mRNA was a significant independent risk factor for peritoneal recurrence (P = 0.027). CONCLUSION These results suggest that p-CEA mRNA is a reliable prognostic factor and predictor of peritoneal recurrence in gastric cancer.

Abstract
BACKGROUND AND AIMS Intraperitoneal carcinomatosis accounts for 25-35% of recurrences of colorectal cancer. Studies demonstrate that peritoneal carcinomatosis is not necessarily a terminal condition with no options for treatment or cure. RESULTS The combination of aggressive cytoreductive surgery and intra-abdominal hyperthermia chemotherapy improves long-term overall survival in selected patients but is a time-consuming procedure (approx. 12 h) and entails high mortality (5%) and morbidity (35%)). Most commonly used drugs are mitomycin C and platinum compounds, which have synergistic toxic effects on tumor cells when hyperthermia is applied. CONCLUSION Since combined treatment seems promising only in peritoneal carcinomatosis stages I and II, the precondition for a reasonable combined treatment is careful staging. The mode of chemotherapy, the kind of drugs used for chemoperfusion, the timing of surgery, and the role of additional systemic chemotherapy must be evaluated in randomized studies.

Abstract
Gastric cancer disseminates by hematogenous, lymphatic, and transcoelomic routes. For maximal containment of the malignant process, perioperative intraperitoneal chemotherapy is necessary in two groups of patients in whom the primary cancer can be resected. Those patients who have been resected for cure and have a high likelihood of microscopic residual disease require intraperitoneal chemotherapy. This includes all T3 and T4 patients, and patients with N2 nodes present. A series of randomized and nonrandomized clinical studies have established the benefits of perioperative intraperitoneal chemotherapy in this group of patients. Patients with stage IV disease who are able to undergo a palliative resection require these treatments if peritoneal seeding is observed. Systemic chemotherapy is largely ineffective for peritoneal seeding, while intraperitoneal chemotherapy is most likely to produce a response with small volume, surgically debulked carcinomatosis. In addition, intraperitoneal chemotherapy can eliminate the future development of debilitating ascites. Sufficient data are available from the gastric cancer literature to support the use of these combined treatments on a routine basis if the primary cancer is resectable and gastrointestinal function can be reestablished.

Abstract
Peritoneal metastases are a common sequela of gastrointestinal malignancy. The treatment of peritoneal metastases through use of aggressive surgical cytoreduction including peritonectomy, coupled with IPHC has now been reported in several large single institution series. The available literature suggests that in experienced hands and with appropriate patient selection, cytoreduction, and IPHC can be an effective therapy, particularly when all macroscopic tumor deposits are removed. Different techniques involving the administration of intraperitoneal chemotherapy have been reported including early postoperative, closed intraoperative, the open or coliseum technique, and the open technique using a PCE device. All techniques have been associated with low mortality and morbidity that is significant, but generally consistent with other major surgical procedures. Commonly reported complications of IPHC include prolonged ileus, fistula, abscess, and thrombosis. In theory, the coliseum and PCE techniques may have less associated morbidity due to improved heat distribution, however, this remains to be definitively proven in a controlled clinical trial. Such controlled studies are critical to defining the best techniques of IPHC administration and the appropriate role for this treatment regimen in patients with peritoneal metastases.

Abstract
BACKGROUND Peritoneal dissemination is the most frequent mode of recurrence in patients with gastric cancer. We tried to identify factors that predict peritoneal recurrence with high sensitivity. STUDY DESIGN Clinical and pathologic data from 587 consecutive patients with gastric cancer were reviewed retrospectively. The stepwise Cox proportional hazards regression model was used to assess the prognostic significance of the magnitude of serosal changes. Multiple stepwise logistic regression analysis was used to determine factors associated with peritoneal recurrence in 375 patients who underwent curative resection. RESULTS The 5-year survival rate of patients with S2 disease (greatest dimension of macroscopic serosal changes >/= 2.5 cm) was 18%, which was worse than S0 (no serosal changes) and S1 disease (macroscopic serosal changes < 2.5 cm)(p < 0.001). Patients with S0 tumors who underwent curative resection had the best 5-year survival rate. Multivariate analyses indicated that the magnitude of serosal changes was an independent prognostic factor for survival both overall and after curative resection. Logistic regression analysis showed that peritoneal recurrence was more than four times as likely with S2 than with S0 or S1 tumors. The sensitivity for predicting peritoneal recurrence was 79%; the sensitivity of cytologic examination was 38%. CONCLUSIONS Magnitude of serosal changes is easy to measure intraoperatively and predicts peritoneal recurrence of gastric cancer with greater sensitivity than conventional peritoneal lavage cytology.

Abstract
UNLABELLED The five years survival rate for patients with gastric cancer is 15-25%. With the aim of improving survival, chemotherapy has been used in different adjuvant settings. Similarly, but with the aim of improving quality of life and prolonging life, chemotherapy has been used extensively in metastatic disease. In this review we have included studies of systemic and intraperitoneal chemotherapy given before, during or after operation and for advanced disease. A meta-analysis has been made on the 21 randomised studies that used adjuvant systemic chemotherapy postoperatively. A significant survival benefit for the patients treated postoperatively compared with controls was identified (odds ratio (OR) 0.84, 95% confidence interval (CI) 0.74 to 0.96). When western and Asian studies were analysed separately we found no survival benefit for the treated patients in the western groups (OR 0.96 (95 CI 0.83 to 1.12)). Flaws in the conduct of several trials made it difficult to draw firm conclusions, including the exclusion of a small but clinically meaningful survival benefit. Preoperative or neoadjuvant chemotherapy has shown effects in some patients, but no significant benefit was found in the few randomised studies. The few studies that reported intraperitoneal therapy showed no detectable survival benefit either. In patients with advanced disease, four small randomised studies found significantly longer survival in the treated patients. The survival benefit is in the range of 3-9 months, and there were also improvements of the quality of life. Several drug combinations have been tested, however, with no confirmed superiority for a particular regimen. CONCLUSIONS Adjuvant chemotherapy cannot be recommended as a routine because of the lack of confirmed beneficial effects. Some patients with advanced disease will have a clinically important benefit from palliative chemotherapy, so this can be recommended for patients who are otherwise in good health.

Abstract
Perioperative intraperitoneal chemotherapy provides effective prevention of peritoneal recurrence after resection in advanced gastric cancer, especially in gastric cancer with serosal invasion. With improved local-regional control, improved survival rate for advanced gastric cancer is achieved. This type of regional chemotherapy is an independent treatment-related prognostic factor for advanced gastric cancer. There are several methods of perioperative intraperitoneal chemotherapy. Among them, early postoperative intraperitoneal chemotherapy is simple and easy to perform.

Abstract
This study investigates the sensitivity and specificity of cytology, qualitative, and real-time RT-PCR methods in free cancer cell detection of peritoneal washing from gastric cancer patients. Peritoneal washings were collected from 65 gastric cancer patients for routine cytology and total RNA extraction for qualitative and real-time RT-PCR for CEA. The sensitivity and false-positive rate was 51.1%, 0% for cytology, 48.9% and 5% for qualitative RT-PCR for CEA, and 42.5% and 5% for real-time RT-PCR for CEA. The qualitative and real time RT-PCR results show high concordance rate (89.7%). The highest sensitivity was obtained by the combination of cytology with qualitative RT-PCR for CEA (70.2%). RT-PCR results were positive in 63.6% of cytologic "atypia" cases. Combination of cytology and either of the RT-PCR methods resulted in significantly higher sensitivity than any one of the three methods alone (P < 0.05). There was no definite advantage of the real-time RT-PCR over the conventional RT-PCR.

Abstract
Despite marked decreases in incidence over the last century, particularly in developed countries, gastric cancer is still the second-most common tumor worldwide. Surgery remains the gold standard for the cure of locoregional disease. However, in most countries, the diagnosis is made at an advanced stage, and the 5-year survival for surgically resectable disease stays far below 50%. The efficacy of chemotherapy and/or radiation therapy in addition to surgery has been actively studied over the last 30 years. Unfortunately, with few exceptions, most studies of adjuvant therapy in gastric cancer have given deceiving results. The purpose of this review is to address the reasons for our failure to objectivate an improvement in the cure of gastric cancer with adjuvant treatment in most trials, and to consider potential solutions. The low efficacy of chemotherapy regimens available up to now may have hampered our progress. In addition, many previous studies suffered limitations of design or methodology (e.g. low accrual, inadequate disease stage selection, inadequate surgical treatment) that may have obscured a treatment effect. Furthermore, the reduced treatment tolerance of post-gastrectomy patients, perhaps due to their poor nutritional status, results in decreased or delayed adjuvant systemic therapy, with potential adverse consequences in its efficacy. Among potential solutions, the arrival of new drugs, taxanes and topoisomerase I inhibitors in particular, which have shown encouraging results in metastatic disease, may increase the impact of chemotherapy in a multidisciplinary treatment approach. Pre-treatment with chemotherapy and/or radiation therapy prior to surgery may also be advantageous, averting the problems associated with post-surgical treatment. Such an approach has been shown to be feasible in phase II studies, and is relatively well tolerated by patients. Several carefully designed randomized phase III trials are underway to answer this question.

Abstract
BACKGROUND The treatment options for the 10-20 per cent of patients with gastric cancer who present with peritoneal dissemination are extremely limited and no standard approach exists. METHODS The feasibility of using intraperitoneal chemotherapy to treat gastric cancer with intra-abdominal gross residual lesions after palliative gastrectomy with maximal cytoreduction was investigated. Early postoperative intraperitoneal chemotherapy started on the day of operation with 5-fluorouracil 500 mg/m2 and cisplatin 40 mg/m2 (days 1-3) over a 4-week interval. RESULTS Of the 53 patients enrolled between July 1994 and December 1998, 49 were eligible. The progression-free survival (PFS) was 7 months and the overall survival was 12 months. In multivariate analysis, performance status was the only significant defining factor for PFS (P = 0.009). The predominant toxicity was neutropenia and nausea/vomiting. The relative dose intensity of 5-fluorouracil and cisplatin was 89 and 63 per cent respectively. CONCLUSION Performance status emerged as a major determining factor for prognosis and patient selection for early postoperative intraperitoneal chemotherapy in patients with advanced gastric cancer after maximally cytoreductive surgery.

Abstract
The peritoneal surface remains an important failure site for patients with colorectal cancer. Peritoneal metastases of colorectal cancer are at present considered equal to distant metastatic disease. Consequently, peritoneal carcinomatosis is treated with systemic chemotherapy and surgery only to palliate complications such as obstruction. Despite the development of new chemotherapeutic agents and combinations, the results remain disappointing with a limited impact on survival. Colorectal carcinoma cells are relatively resistant to chemotherapy. Intraperitoneal chemotherapy seems to be an attractive approach in the treatment of high-risk colorectal cancer and peritoneal carcinomatosis from colorectal origin providing high local drug concentration with limited systemic side effects. Adjuvant early postoperative intraperitoneal chemotherapy is worthwhile for consideration as treatment option after resection of high-risk colorectal cancer. In the treatment of peritoneal carcinomatosis postoperative intraperitoneal chemotherapy leads to inadequate exposure of the peritoneal surface. Only an intraoperative intraperitoneal chemotherapy performed with direct cytotoxic drugs such as MMC and cisplatin overcome this problem. The limited drug penetration in tissue implies the need for extensive cytoreductive surgery. The results of phase II studies suggest that an increased median survival can be achieved with this approach. The natural history of this disease and the heterogeneity of the patients are such that only a randomized trial design will adequately answer the question whether regional treatment of patients with peritoneal dissemination of colorectal cancer actually prolongs survival. The results of such a study are to be expected in approximately 2 years time.

Abstract
BACKGROUND In recent years surgical cytoreduction followed by intra-operative hyperthermic intraperitoneal chemotherapy (HIPEC) was introduced as treatment modality in patients with peritoneal surface malignancy. In the current review the rational for this approach, the prerequisites and the different techniques used are discussed. METHODS A literature search through PubMed was performed. RESULTS Pharmacokinetic studies have shown an important dose advantage for intraperitoneal versus intravenous application. Hyperthermia enhances the penetration of cytostatic drugs into tumour tissue and also shows synergism with various cytostatic drugs. The penetration depth of drugs into tissue is limited, therefore HIPEC can only be effective in patients with minimal residual disease after (aggressive) surgery. HIPEC can be conducted in various ways, without clear proven advantage of one method over the others. Local complications after this combined treatment approach are mainly surgery related. Intraperitoneal chemotherapy may cause systemic toxicity, dependent on the drug used. In randomised studies cytoreductive surgery followed by HIPEC has proven its value in the prevention of peritoneal dissemination in gastric cancer. Phase II data on HIPEC in peritoneal carcinomatosis of colorectal origin and pseudomyxoma peritonei are promising, but randomised studies are still not available. CONCLUSION Aggressive surgical cytoreduction and HIPEC in patients with peritoneal surface malignancy has a clear rational and seems to have clinical value.

Abstract
BACKGROUND At present the most reliable method for the diagnosis of peritoneal micrometastasis of gastric cancer is peritoneal wash cytology, but the sensitivity of this method is low. The aim of the present study was to verify whether carcinoembryonic antigen (CEA) reverse transcriptase-polymerase chain reaction (RT-PCR) assay can enhance the sensitivity and specificity of conventional cytology, and to determine how this technique can improve the accuracy of peritoneal recurrence. METHODS The present study included 230 patients with gastric cancer. Preoperative peritoneal wash was done by a paracentesis, followed by conventional cytology, CEA measurement, and CEA RT-PCR of recovered fluid. RESULTS The CEA RT-PCR assay yielded 40 (17%) positives, which included none of the 26 patients with benign disease. The incidence of positive cytology and CEA level in wash fluid was 19% and 15%, respectively. Logistic stepwise regression analysis revealed that lymph node status, depth of invasion, venous invasion, and the results of peritoneal cytological examination, and CEA RT-PCR assay were independently related to peritoneal recurrence. The CEA level in the wash fluid was not related to peritoneal recurrence. Peritoneal cytological examination was the most significant predictive factor for peritoneal recurrence with a sensitivity of 46%, specificity of 94% and accuracy of 73%, while the corresponding values of the CEA RT-PCR assay were 31%, 95%, and 73%. Combining cytological examination with CEA RT-PCR assay resulted in a sensitivity rate for peritoneal recurrence of 57%, an 11% improvement over that of cytology alone. CONCLUSION The data indicate that the use of a combination of CEA RT-PCR and cytological assay is more likely to identify patients who will develop peritoneal recurrence. This may be useful for the classification of patients for the most suitable therapeutic trials.

Abstract
Peritoneal seeding from colorectal cancer has a very poor prognosis and is relatively resistant to systemic chemotherapy. We performed a phase I/II trial to investigate the feasibility and effectiveness of extensive cytoreductive surgery in combination with intra-operative hyperthermic intraperitoneal chemotherapy (HIPEC) in these patients. 29 patients with peritoneal carcinomatosis of colorectal origin without evidence of distant metastases underwent cytoreductive surgery and intra-operative HIPEC with mitomycin-C (MMC), followed by systemic chemotherapy with 5-fluorouracil (5-FU)/leucovorin. Surgical complications occurred in 11 patients (38%). One patient died directly related to the treatment, resulting in a mortality rate of 3%. MMC toxicity existed mainly of leucocytopenia (in 15 patients; 52%). After a median follow-up of 38 months (range 26-52 months) we found a 2- and 3-year survival rate (Kaplan-Meier) of 45 and 23%, respectively. Extensive cytoreductive surgery and HIPEC is feasible in patients with peritoneal seeding of colorectal cancer. First results suggest that a higher median survival could be achieved compared with conventional palliative surgery and systemic chemotherapy, therefore a randomised phase III study is now being conducted.

Abstract
BACKGROUND Peritoneal metastasis is the most frequent cause of death in patients with gastric cancer. Detection of free cancer cells in the peritoneal cavity at the time of surgery, therefore, is considered to be of great value in predicting the peritoneal recurrence and accordingly in the prognosis in patients with gastric cancer. This study examined the clinical significance of intraoperative determination of carcinoembryonic antigen (CEA) levels in peritoneal washes (pCEA) in patients with gastric cancer. METHODS CEA levels in peritoneal washes were correlated retrospectively with several clinicopathologic factors including clinical outcome in 56 patients with resectable gastric cancer. RESULTS Among several clinicopathologic factors, the depth of tumor invasion significantly and independently correlated with pCEA levels as revealed by multivariate stepwise logistic regression analysis. A significant difference in overall survival rates was observed between pCEA-positive and pCEA-negative groups: 5-year survival rates were 95.7% in pCEA-negative and 20% in pCEA-positive patients (P <0.0001). Multivariate analysis indicated that pCEA level is a statistically significant independent prognostic factor for the survival of patients with gastric cancer, and is an important factor for predicting peritoneal recurrence. CONCLUSIONS pCEA could be a potential predictor of a poor prognosis as well as peritoneal recurrence in patients with gastric cancer. We believe that this information could contribute to determining the optimal intraoperative and postoperative therapeutic plan including adjuvant chemotherapy of gastric cancer.

Abstract
Detection of free cancer cells in the peritoneal cavity by RT-PCR using carcinoembryonic antigen (CEA) as a target gene is a more sensitive predictor of peritoneal dissemination than conventional cytology in gastric-cancer patients. Difficulties with this method are the lack of quantitative assessment of free cancer cells and the length of time before completion. To overcome these problems, we have established a rapid and quantitative detection method using a novel real-time fluorescence PCR system (LightCycler). Using this device with hybridization probes as fluorophores, we detected CEA mRNA in peritoneal washes during surgery (within 3 hr) without any post-PCR procedure. This method could reproducibly quantitate 10 to 10(6) CEA-expressing colon carcinoma cells per 10(7) peripheral blood leukocytes, a comparable sensitivity to conventional RT-PCR with a wide dynamic range. Analysis of peritoneal washes from 109 gastric-cancer patients with this assay revealed relative values of CEA transcripts that correlated well with the depth of tumor invasion (p < 0.01). Average values of CEA transcript in peritoneal washes in patients with cytology (-)/RT-PCR(-), cytology (-)/RT-PCR(+) and cytology (+)/RT-PCR(+) results were 0.64, 1,525 and 6,715, respectively. Moreover, CEA transcripts in peritoneal washes in patients with synchronous peritoneal metastasis were more than 50-fold higher than in those without metastasis. These results suggest a positive correlation between CEA mRNA levels in peritoneal washes and prognosis. We conclude that real-time RT-PCR with hybridization probes is a sensitive, quantitative, specific and rapid method to detect free cancer cells in peritoneal washes. This clinically relevant system is a powerful technique to evaluate the risk of peritoneal recurrence in patients with gastric cancer.

Abstract
BACKGROUND Surgical treatment of intra-abdominal cancer is often followed by local recurrence. In a subgroup of patients, local recurrence is the sole site of disease, reflecting biologically low-grade malignancy. These patients might, therefore, benefit from local treatment. Recently, debulking surgery followed by hyperthermic chemoperfusion has been proposed in the treatment of locally advanced or recurrent intra-abdominal cancer. This paper reviews the rationale and assesses the currently accepted indications for and results of this novel treatment. METHODS A systematic web-based literature review was performed. Information was also retrieved from handbooks, congress abstracts and ongoing clinical trials. RESULTS A growing body of experimental evidence supports the use of hyperthermia combined with chemotherapy as an adjunct to cytoreductive surgery. Randomized clinical trials are available to support its use in the treatment and prevention of peritoneal carcinomatosis following resection of pathological tumour stage pT3 or pT4 gastric cancer; several other phase III trials are ongoing. Numerous phase I and II trials have reported good results for various other indications, with acceptable morbidity and mortality rates. Case mix, limited patient numbers and absence of a standardized technique are, however, a drawback in many of these series. CONCLUSION For a subgroup of patients with peritoneal cancer without distant disease, debulking surgery followed by hyperthermic chemoperfusion may offer a chance of cure or palliation in this otherwise untreatable condition. This novel therapy should, however, be considered experimental until further results from ongoing phase III trials become available.

Abstract
Gastric cancer is still a major health problem and a leading cause of cancer mortality despite a worldwide decline in incidence. Environmental and Helicobacter pylori (Hp) acting early in life in a multistep and multifactorial process may cause intestinal type carcinomas, whereas genetic abnormalities are related more to the diffuse type of disease. Primarily due to early detection of the disease, the results of treatment for gastric cancer have improved in Japan, Korea and several specialized Western centres. Surgery offers excellent long-term survival results for early gastric cancer (EGC). Advances in diagnostic and treatment technology have contributed to a trend towards minimal invasive surgery such as endoscopic mucosal resection (EMR) and laparoscopic surgery for selected mucosal cancers. In the Western world, however, more than 80% of patients at diagnosis have an advanced gastric cancer with a poor prognosis. The aim of surgery is complete removal of the tumour (UICC R0-resection), which is known to be the only proven, effective treatment modality and the most important treatment-related prognostic factor. Gastrectomy with preservation of the spleen and pancreas in most cases is the standard procedure. However, at present there is no consensus about the optimal extent of lymph-node dissection. The hypothesis that extended (D2) lymph-node dissection leads to improved survival has not been confirmed in randomized trials. Results from specialized centres and ongoing multi-institutional randomized trials, however, indicate that D2 dissection, with preservation of the spleen and pancreas, can be performed with the same safety as a D1 dissection. Furthermore, in 50% of patients with node-positive disease, the extraperigastric N2 nodes are involved (N2 disease) and thus an R0-resection is achievable only by a D2 node dissection resulting in a 5-year survival of about 30% for such patients. However, even after a D2 node dissection with curative potential, disease recurs in two-thirds of patients with locally advanced gastric cancer (LAGC) and is rapidly fatal. The need for an adjuvant treatment is obvious, but at present there is no such treatment of proven effectiveness. Promising results with preoperative chemotherapy, which increases the R0-resection rate, and intra-or early postoperative intraperitoneal chemohyperthermia to prevent peritoneal dissemination have been reported. However, randomized trials are necessary before these combined treatments become widely accepted. Present data indicate that the treatment of gastric cancer has become more and more sophisticated with a tailored therapy for individual cases. Treatment includes a broad spectrum of therapeutic options from EMR for selected mucosal cancers to aggressive combined treatment for LAGC. Precise knowledge of patterns of recurrence and metastases, critical evaluation of clinicopathologic variables, integration of high technology into diagnosis to predict accurately pre-treatment staging, and the surgeon's ability to perform minimally invasive surgery and D2 node dissection technique are necessary for an appropriate treatment option. All these prerequisites are best ensured by management in experienced surgical oncology units.

Abstract
Malignant mesothelioma of the peritoneum is a rare tumour for which the therapeutic approach has not yet been standardized. The efficacy of the current regimes is limited. Effective locoregional therapy is crucial, since this tumour is most often confined to the peritoneal cavity at the time of the initial diagnosis and remains there for much of its clinical course. If and when haematogenous metastases occur, they rarely contribute to the death of the patient, which is often caused by the overgrowth of the primary tumour and its local complications. A case of diffuse malignant peritoneal mesothelioma treated by cytoreductive surgery and continuous hyperthermic peritoneal perfusion with cisplatin is reported. The patient received systemic combination chemotherapy postoperatively. She is in good condition and free of disease 28 months after her treatment. Continuous hyperthermic peritoneal perfusion chemotherapy has recently been used in patients with secondary peritoneal carcinomatosis from digestive and gynecological malignancies with promising results. It is also possible that the same treatment alone or in combination with systemic chemotherapy may be effective in the treatment of primary peritoneal malignancies, as in the case of diffuse peritoneal mesothelioma.

Abstract
BACKGROUND Intraoperative hyperthermic peritoneal chemotherapy (IHPC) after total gastrectomy for advanced, serosa-penetrating gastric cancer has been demonstrated in several studies to reduce the incidence of peritoneal carcinosis and to prolong survival. METHODS In a prospective pilot study, nine patients with advanced gastric cancer were selected to receive IHPC with Mitomycin and Cisplatin after total gastrectomy and systematic lymphadenectomy. RESULTS All patients had nodal, and four patients distant, metastases. Six patients (66%) suffered from post-operative complications including renal failure, pancreatitis, pancreatic fistula and anastomotic dehiscence. Thirty-day mortality was zero. Six patients died within 3-10 months after surgery. Five of these deaths were related to peritoneal carcinosis and one patient died from cardiac failure 3 months after surgery. Three patients, respectively, have been alive for 12, 20 and 24 months at present, with suspected peritoneal tumour in the last patient. The 2-year probability of survival among our patients receiving IHPC is 29%. CONCLUSION Intraoperative hyperthermic peritoneal chemotherapy carries a high risk of peri-operative complications and was not able to prevent or delay peritoneal tumour recurrence in patients with advanced gastric cancer.

Abstract
Peritoneal dissemination can be prevented by the responsible surgeon at least in part by proper surgical technique used to resect the primary malignancy. What most people do not know is that cancer surgery can do great harm. It can convert a contained malignant condition into a disseminated disease that unnecessarily becomes a deadly process. Containment must be the number one priority of the gastrointestinal cancer surgery. Also, established peritoneal carcinomatosis can be cured if it is attacked in a timely fashion with peritonectomy procedures and heated intraoperative intraperitoneal chemotherapy. Many small changes can make a big difference in survival with gastrointestinal cancer surgery.

Abstract
AIMS Studies on the value of peritoneal tumour cell dissemination for prognosis in gastric cancer using various methods to detect tumour cells have produced conflicting conclusions. We studied the incidence and prognostic relevance of microscopic intraperitoneal tumour cell dissemination in gastric cancer, comparing conventional and immunocytological detection. METHODS Peritoneal wash-outs of 111 consecutive gastric patients without overt peritoneal carcinomatosis, including 75 curatively resected patients, were studied. Sixty patients with benign disorders served as controls. 100 ml of warm NaCl 0.9% was instilled intraoperatively and 20 ml was reaspirated. The specimens were stained peri-operatively with H&E. In the last 47 patients (30 of whom were curatively resected) additional immunostaining with the HEA-125 antibody was performed. The results of cytology were correlated with the TNM categories and with post-operative follow-up. RESULTS Of the patients, 42.3% and 48.9% were positive when conventional and immunocytological staining were employed, respectively. Conventional cytology was significantly associated with the pT and M categories. Immunocytology was significantly associated with the pT, pN and M caterogies. In four of 30 curatively resected patients (13.3%), the results of conventional and immunocytology were different. Three patients with positive immunocytology but negative conventional cytology died during follow-up (median follow-up 45.3 months), whereas one patient with positive conventional but negative immunocytology is still alive. In an univariate analysis 4 years post-surgery, positive immunocytology was significantly associated with an unfavourable prognosis in patients with curatively resected gastric cancer. While only 28.6% (six of 21) of the patients with negative immunocytology had died, this proportion increased to 77.8% (seven of nine) with positive immunocytology (P=0.018). The mean survival of negative vs positive patients amounted to 1205+/-91 vs 772+/-147 days (P=0.007). In contrast, in conventional cytology we found no significantly different survival time between negative and positive patients. CONCLUSIONS Immunocytology seems to be superior to conventional cytology and should be preferred.

Abstract
BACKGROUND AND OBJECTIVES Free cancer cells in the abdominal cavity exfoliated from a tumor are considered to be responsible for peritoneal dissemination, the most frequent pattern of failure in gastric carcinoma patients treated with curative surgery. METHODS A prospective survival analysis was performed with 91 gastric carcinoma patients treated by potentially curative resection. Cytology was performed for all the patients. The method of Kaplan and Meier was used to construct curves with diagnosis of peritoneal dissemination and cancer death as the end points. Multivariate analysis by Cox's proportional hazards model was performed to identify independent prognostic factors of significance. RESULTS Patients with a positive cytology result were confirmed to have a greater risk for recurrence in the pattern of peritoneal carcinomatosis and hence a significantly inferior prognosis. Positive cytology was the only significant independent prognostic factor among the curatively resected patients with advanced gastric carcinoma. CONCLUSIONS Peritoneal lavage cytology should be employed for all advanced cancer undergoing potentially curative resection for added accuracy in the stage classification. The results should also reflect the eligibility of the patients for future clinical trials involving perioperative intraperitoneal chemotherapy.

Abstract
BACKGROUND This study examined the clinical value of intraoperative peritoneal lavage for cytological examination in patients with gastric cancer. Peritoneal dissemination is the most frequent mode of recurrence for this tumor. METHODS A retrospective of lavage findings, other factors, and outcome was performed in 1,297 patients with gastric cancer who underwent intraoperative peritoneal lavage. RESULTS The 5-year survival rate of patients with positive lavage cytology was only 2%. Patients who underwent curative resection and had negative cytology had a significantly better 5-year survival rate (P < 0.001). Even among patients with macroscopic peritoneal dissemination, the survival rate was significantly better with negative cytology, which reflected fewer free cancer cells in the peritoneal cavity. Serum concentrations of carcinoembryonic antigen and carbohydrate antigen 19-9 were significantly higher in patients with positive cytology. Multivariate analyses indicated that intraoperative cytological findings was an independent prognostic factor for survival, and was the most important factor for predicting peritoneal recurrence. CONCLUSIONS Intraoperative peritoneal lavage cytology is important in predicting survival and peritoneal recurrence in gastric cancer.

Abstract
The validity of lavage cytology for accurate gastric cancer staging is demonstrated in this study. Between 1988 and 1996, 29 cases (8. 4%) were revealed as positive among 347 patients with resectable gastric cancer in whom peritoneal lavage cytology was performed. The survival rate of cytology-positive patients in each stage was found to be worse than that of all other patients in the same stage. The prognostic factors selected by the univariate analysis were enrolled for multivariate analysis using Cox's proportional hazards model with the backward stepwise procedure. As a result, although cytology finding was selected as an independent prognostic factor, macroscopic finding of dissemination was not selected. Our data indicate that positive cytology findings indicated a poor prognosis, and therefore the results of peritoneal lavage cytology should be included as a factor in gastric cancer staging.

Abstract
Free cancer cells exfoliated from the cancer-invaded serosa contribute to peritoneal dissemination, the most frequent pattern of recurrence in gastric carcinoma patients. This study was designed to evaluate the prognostic relevance of such free cells in peritoneal washes detected by reverse transcriptase-polymerase chain reaction (RT-PCR) and cytology. RT-PCR analysis with primers specific for carcinoembryonic antigen and conventional cytologic examination by Papanicolaou staining were performed on peritoneal washes, collected at laparotomy from 148 gastric carcinoma patients. Prognostic analyses were performed with 1) death due to cancer recurrence and 2) peritoneal dissemination as endpoints. RT-PCR was found to be more sensitive than cytologic examination for detection of free cancer cells in the peritoneal washes, with a higher detection rate for each of the T categories in the tumor-node-metastasis (TNM) classification. Five patients with synchronous or recurrent peritoneal dissemination were found among 17 patients with positive RT-PCR and negative cytologic results. Both positive cytologic results and positive RT-PCR results had significant influences over the survival of patients with advanced gastric carcinomas (n = 75, p < .002). Detection of free cancer cells in peritoneal washes, most reliably by RT-PCR, is promising as a predictor of peritoneal dissemination in patients with gastric carcinoma.

Cytological examination of peritoneal washes is a useful predictor of peritoneal recurrence in gastric carcinoma patients. In the present study, even more sensitive detection of free cancer cells could be achieved through amplification of carcinoembryonic antigen (CEA) mRNA by means of the reverse transcriptase-polymerase chain reaction (RT-PCR). CEA was first confirmed to be present in all the gastric cancer cell lines examined, irrespective of the differentiation degree, and absent in blood and mesothelium, indicating the specificity of this approach for detection of carcinoma cells in peritoneal lavage fluid. In sensitivity tests, CEA RT-PCR proved to be capable of detecting 10 carcinoma cells per sample. Peritoneal washes of 15 of 48 gastric carcinoma patients, including all 10 patients with positive cytology results, proved positive for CEA mRNA. None of the 5 patients with benign disease was positive. Moreover, a close association with the depth of cancer invasion was established. The results indicate that the assay is more sensitive for detection of free carcinoma cells in the peritoneal cavity than conventional cytology. This is the first study to suggest the feasibility of the RT-PCR method for prediction of peritoneal recurrence in gastric cancer patients.

Abstract
PURPOSE Anastomotic leaks after double-stapled low anterior resection were associated with a number of factors related to patient condition, level of anastomosis, and variety of surgery-related and antitumor therapy-related factors. This retrospective analysis of a group of patients with consistent length of rectal stump was undertaken to determine the risk factors of anastomotic leak after low colorectal resection related to surgery and to intraperitoneal chemotherapy. METHODS A group of 165 patients treated with surgery only, surgery with early postoperative intraperitoneal chemotherapy, and surgery with hyperthermic intraoperative and early postoperative intraperitoneal chemotherapy. All patients underwent surgery that used the double-stapled technique with transection of the rectum through its middle third. In univariate and multivariate analysis, the relationship between anastomotic leak rate and extent of colon resection, length of residual colon, presence of left colon, and type of applied treatment was studied. RESULTS With a full length of residual colon, leak rate was 1 percent but increased progressively with the extent of proximal colon resection. Removal of the left colon was associated with the 2.7 odds ratio for anastomotic disruption. Leak rate after surgery only was 6 percent; surgery with normothermic intraperitoneal chemotherapy was 5 percent; and surgery with heated intraperitoneal chemotherapy was 20 percent. CONCLUSIONS In this group of patients with consistent length of residual rectum, the incidence of anastomotic disruption was related to extent of proximal colon resection. Anastomotic integrity was not compromised by normothermic intraperitoneal chemotherapy. Hyperthermic intraperitoneal chemotherapy was associated with high leak rate only when extensive resection of the colon was performed. Variables other than extent of rectal excision are important in causing a leak of colorectal anastomosis.

Abstract
BACKGROUND Peritoneal carcinoma has been regarded as a uniformly lethal clinical entity. A treatment plan combining cytoreductive surgery and heated intraoperative intraperitoneal chemotherapy (HIIC) was devised and tested to treat such patients. The purpose of this study was to evaluate the morbidity and mortality associated with this treatment approach. METHODS Sixty patients with peritoneal carcinomatosis from adenocarcinoma of the colon or appendix were included in the study. Extensive cytoreductive surgery was combined with heated intraperitoneal mitomycin in an intraoperative lavage technique followed by one cycle of early postoperative intraperitoneal 5-fluorouracil. Eleven clinical variables were selected and statistically correlated with morbidity and mortality. RESULTS Twenty-five complications occurred in 21 patients (morbidity = 35%). Morbidity related to gastrointestinal function included anastomotic leak (n=6), bowel perforations (n=5), bile leak (n=3), and pancreatitis (n=2). Four patients presented with severe hematologic toxicity (Grade 3 or 4). There were three cases of postoperative bleeding, one case of abdominal wound dehiscence, and one case of pulmonary embolism. Morbidity was significantly associated with three clinical factors: male sex, high intraabdominal temperature during HIIC, and duration of the surgical procedure. Enteral complications (bowel fistula and anastomotic leak) occurred in patients with a significantly higher number of peritonectomy procedures and a significantly longer operation. Three patients died within 8 weeks after the procedure (mortality = 5%). Mortality was significantly associated with age and intraabdominal temperature. CONCLUSIONS Cytoreductive surgery combined with HIIC is associated with a 35% morbidity rate and a 5% mortality rate. Extensive surgery (duration and number of peritonectomy procedures) and high intraabdominal temperature represent the major risk factors for postoperative morbidity and mortality of patients treated with this new therapeutic approach.

Abstract
Two main approaches are suggested to improve treatment results in resectable gastric cancer: extended lymphadenectomy and adjuvant antitumour therapy. Progress is to some extent stalled by the perception of gastric cancer as a pathophysiologically uniform disease; it has been demonstrated, however, that there are variants of gastric cancer associated with predominantly intra-abdominal spread or with haematogenous metastases. Recent clinicopathological studies have provided information about the mechanisms of this metastatic diversity. A review of clinical trials suggests that no single method of treatment can efficiently address all variants of gastric cancer spread, but new treatment strategies may be based on defining the pathophysiological variant of gastric cancer and selecting adjuvant therapy according to the most probable mode of tumour spread. Treatment should start with surgery which includes a 'reasonably' extended lymphadenectomy aimed at achieving an increased rate of curative resection and more accurate staging. Risk factors for peritoneal spread of tumour require the perioperative use of intraperitoneal chemotherapy. Subsequent adjuvant therapy may be indicated in patients at high risk of further cancer spread or occult metastases, as determined by pathological examination of the resected specimen.

Abstract
Peritoneal carcinomatosis is a major cause of surgical treatment failure in patients with colorectal cancer. In the past patients with this condition have had a lethal outcome. In this study, 64 consecutive patients were treated by the cytoreductive approach, which involved surgery to maximally resect all cancer in the abdomen and pelvis, early postoperative intraperitoneal chemotherapy with 5-fluorouracil (5-FU) and mitomycin C, and three cycles of adjuvant intraperitoneal 5-FU with systemic mitomycin C. The clinical features that may affect prognosis were assessed and critically analyzed statistically. Peritoneal implant size of < 5 cm present in the abdomen and pelvis at the time of exploration correlated with a good prognosis (p < 0.0001), as did complete cytoreduction with tumor removed to nodules < 2.5 mm (p < 0.0001). Involvement of only one or two of the five abdominopelvic regions, compared to three or more regions, was a significant determinant of prognosis (p < 0.0001). Finally, a mucinous histologic type correlated adversely with prognosis when compared to intestinal-type adenocarcinomas (p < 0.001). These data suggest that patients with small-volume peritoneal seeding from colon cancer should be treated with cytoreductive surgery and aggressive regional and systemic chemotherapy in an attempt to achieve long-term disease-free survival.
