Abstract
AIMS Gastric cancer in Western countries is often diagnosed in an advanced stage and prognosis is poor. We performed a randomised trial with pre-operative FAMTX vs. surgery alone in order to evaluate the effect of pre-operative chemotherapy on resectability and survival. METHODS Patients with proven adenocarcinoma of the stomach were randomised to receive four courses of chemotherapy using 5-Fluorouracil, doxorubicin and methotrexate (FAMTX) prior to surgery or to undergo surgery alone. RESULTS Fifty-nine patients were randomised; 29 patients were allocated to the FAMTX regimen prior to surgery and 30 patients had surgery alone. Resectability rates were equal for both groups. Complete or partial response was registered in 32% of the FAMTX group. With a median follow-up of 83 months the median survival since randomisation is 18 months in the FAMTX group vs. 30 months in the surgery alone group (p=0.17). CONCLUSIONS This trial could not show a beneficial effect of pre-operative FAMTX. Until large randomised studies prove otherwise, adequate surgery without delay is the best treatment for operable gastric cancer.

Abstract
PURPOSE In the West, curative (R0) resection is achieved in approximately 50% of patients with localized gastric carcinoma, and more than 60% die of cancer following an R0 resection. A multi-institutional study of preoperative chemoradiotherapy was done to assess the R0 resection rate, pathologic complete response (pathCR) rate, safety, and survival in patients with resectable gastric carcinoma. PATIENTS AND METHODS Operable patients with localized gastric adenocarcinoma were eligible. Staging also included a laparoscopy and endoscopic ultrasonography (EUS). Patients received up to two 28-day cycles of induction chemotherapy of fluorouracil, leucovorin, and cisplatin, followed by 45 Gy of radiation plus concurrent fluorouracil. Patients were then staged and surgery was attempted. RESULTS Thirty-four patients were registered at three institutions. One ineligible patient was excluded. Most patients had a promixal cancer and EUST3N1 designation. Twenty-eight (85%) of 33 patients underwent surgery. The R0 resection rate was 70% and pathCR rate was 30%. A pathologic partial response (< 10% residual carcinoma in the primary) occurred in eight patients (24%). EUS T plus N and postsurgery T plus N correlation showed significant downstaging (P = <.01). The median survival time for 33 patients was 33.7 months. Patients achieving a pathCR or pathPR had a significantly longer median survival time (63.9 months) than those achieving less than pathPR (12.6 months; P =.03). There were two treatment-related deaths. CONCLUSION Our data suggest that the three-step strategy of preoperative induction chemotherapy followed by chemoradiotherapy resulted in substantial pathologic response that resulted in durable survival time. This strategy is worthy of a direct comparison with postoperative adjuvant chemoradiotherapy.

Abstract
Multimodality and quality controlled treatment result in improved treatment outcome in patients with solid tumours. Quality assurance focuses on identifying and reducing variations in treatment strategy. Treatment outcome is subsequently improved through the introduction of programs that reduce treatment variations to an acceptable level and implement standardised treatment. In chemotherapy and radiotherapy, such programmes have been introduced successfully. In surgery however, there has been little attention for quality assurance so far. Surgery is the mainstay in the treatment of patients with gastric and rectal cancer. In gastric cancer, the extent of surgery is continuously being debated. In Japan, extended lymph node dissection is favoured whereas in the West this type of surgery is not routinely performed with two large European trials concluding that there is no survival benefit from regional lymph node clearance. Post-operative chemoradiation is part of the standard treatment in the United States, although its role in combination with adequate surgery has not been established yet. These global differences in treatment policy clearly relate to the extent and quality of surgical treatment. As for gastric cancer, surgical treatment of rectal cancer patients determines patient's prognosis to a large extent. With the introduction of total mesorectal excision, local control and survival have improved substantially. Most rectal cancer patients receive adjuvant treatment, either pre- or post-operatively. The efficacy of many adjuvant treatment regimens has been investigated in combination with conventional suboptimal surgery. Traditional indications of adjuvant treatment might have to be re-examined, considering the substantial changes in surgical practise. Quality assurance programs enable the introduction of standardised and quality controlled surgery. Promising adjuvant regimens should be investigated in combination with optimal surgery.

Abstract
BACKGROUND The prognosis after surgery for oesophagogastric cancer remains poor. METHODS This review clarifies current indications for neoadjuvant therapy for oesophageal and gastric cancer. A systematic literature research and evaluation of data from international cancer meetings were carried out. RESULTS Recently published results of large randomized phase III trials underscore the potential value of neoadjuvant treatment for oesophagogastric cancer. However, it remains uncertain which subgroups of patients should routinely undergo preoperative therapy. Metabolic response evaluation during neoadjuvant treatment is a promising tool for the selection of responding patients. CONCLUSION Neoadjuvant chemotherapy is a valid option for locally advanced oesophageal and gastric cancer. In the future, more effective and better tolerated treatment strategies, tailored to the specific tumour characteristics of each individual, should be possible.

Abstract
PURPOSE The extent of lymph node dissection appropriate for gastric cancer is still under debate. We have conducted a randomized trial to compare the results of a limited (D1) and extended (D2) lymph node dissection in terms of morbidity, mortality, long-term survival and cumulative risk of relapse. We have reviewed the results of our trial after follow-up of more than 10 years. PATIENTS AND METHODS Between August 1989 and June 1993, 1,078 patients with gastric adenocarcinoma were randomly assigned to undergo a D1 or D2 lymph node dissection. Data were collected prospectively, and patients were followed for more than 10 years. RESULTS A total of 711 patients (380 in the D1 group and 331 in the D2 group) were treated with curative intent. Morbidity (25% v 43%; P <.001) and mortality (4% v 10%; P =.004) were significantly higher in the D2 dissection group. After 11 years there is no overall difference in survival (30% v 35%; P =.53). Of all subgroups analyzed, only patients with N2 disease may benefit of a D2 dissection. The relative risk ratio for morbidity and mortality is significantly higher than one for D2 dissections, splenectomy, pancreatectomy, and age older than 70 years. CONCLUSION Overall, extended lymph node dissection as defined in this study generated no long-term survival benefit. The associated higher postoperative mortality offsets its long-term effect in survival. For patients with N2 disease an extended lymph node dissection may offer cure, but it remains difficult to identify patients who have N2 disease. Morbidity and mortality are greatly influenced by the extent of lymph node dissection, pancreatectomy, splenectomy and age. Extended lymph node dissections may be of benefit if morbidity and mortality can be avoided.

Abstract
Adenocarcinoma of the stomach is advanced enough in some patients to preclude curative treatment, but many gastric cancer patients have what appears to be localized disease that is amenable to surgical resection, which is the only truly effective treatment. Long-term results of what appear to be "curative resections" are relatively poor, however, and new management tools such as sentinel lymph node biopsy, recently promising adjunctive therapies (such as radiochemotherapy), and the organization of the order of treatment combinations do require further study with an eye to improving outcomes. However, there appears to be little hope for a dramatic improvement in treatment results from these innovations for patients with established gastric cancer. Fortunately, gastric cancer in the United States has gone from being the number one cause of cancer death in our population 50 years ago to that of being the number eight cause of cancer death at this time. This intriguing major decrease in the incidence of this disease must be considered secondary to one or more changes in our own environment that we hope will be exploitable in the future. As with cancers of all types and in all sites, a prevention strategy may prove more effective than the treatment strategies that are outlined here. The management strategies outlined are hopefully only temporary ones until we are able to develop a better handle on primary prevention.

Abstract
Following the successful introduction of oxaliplatin into the management of advanced colorectal cancer, its clinical utility is currently being investigated in a variety of other malignancies, including cancers of the upper gastrointestinal tract. In advanced pancreatic cancer, oxaliplatin has been found to be clinically effective in phase II trials in which it was combined with either 5-fluorouracil (5-FU) or gemcitabine, the current standard chemotherapy for this disease. In a phase II trial involving 67 patients, the combination of oxaliplatin and 5-FU in a high dose infusional regimen (n = 31) achieved an objective response rate of 9.7%, stable disease for at least three cycles in 48.4% of patients, tumour growth control in 58% of patients, a median time to progression of 4.9 months and median overall survival reaching 9.2 months. In combination with gemcitabine in a phase II trial involving 64 patients with metastatic (n = 34) or locally advanced (n = 30) pancreatic cancer, there was an objective response rate of 30.6%, treatment benefit in 39.7%, a median progression-free survival of 5.3 months and again a median overall survival of 9.2 months. Response rates and survival times did not differ between locally advanced and metastatic disease. On the basis of these encouraging results, phase III studies of oxaliplatin in advanced pancreatic cancer are now in progress in Europe and the United States. In metastatic gastric cancer, a phase II study investigated the combined use of oxaliplatin and 5-FU using the FOLFOX6 regimen in 53 patients, of whom 49 were evaluable for efficacy. The objective response rate was 44.9% and the median duration of response was 7.9 months. Large phase III trials of oxaliplatin-based treatment for advanced gastric cancer are now in progress. Oxaliplatin is also being investigated in oesophageal cancer and several other gastrointestinal tumours. In summary, oxaliplatin is emerging as an effective and highly promising chemotherapeutic agent for the treatment of upper gastrointestinal malignancies.

Abstract
The past decade has seen many advances in knowledge about gastric cancer. Notably, tumour biology and lymphatic spread are now better understood, and treatment by surgical and medical oncologists has become more standardised. Since refrigerators have replaced other methods of food conservation, Helicobacter pylori has become a factor in the cause of gastric cancer. Cancers that arise at the oesophagogastric junction might be further examples of wealth-associated disease. To tailor treatment better, the western hemisphere needs to borrow from the East by establishing screening programmes for early diagnosis, through careful surgical resection, and through detailed analysis of tumour spread. In Europe and the USA, most patients reach treatment with cancers already at an advanced stage. For these patients, three important randomised trials are underway that evaluate combined therapy. Cytostatic drugs, especially angiogenesis inhibitors have proved disappointing; however, basic research efforts to detect familial gastric cancers and to assess minimally residual disease look more hopeful.

Abstract
BACKGROUND In view of the lack of consensus on the level and number of lymph nodes to be examined for accurate staging of patients with gastric cancer, our aim was to evaluate the prognostic significance of lymph node status in a large European monoinstitutional experience. METHODS A review was made of our prospective database from 1980 to 2000, when 314 of 445 patients operated for gastric adenocarcinoma underwent radical resection (R0) with D2 lymphadenectomy. Survival was determined by the Kaplan-Meier method and differences were assessed by the log-rank test. Multivariate analysis was performed using the Cox proportional hazards model in forward stepwise regression. RESULTS In 277 evaluable patients, 5-year survival was 57% (median follow-up, 48 months; range, 2-251). A total of 7668 lymph nodes were examined (median, 27; range, 11-62). The 5-year survivals according to the metastatic/examined lymph nodes ratio (N ratio) were 14%, 50%, 61%, and 82% in the group of patients with N ratio >25%, 11%-25%, 1%-10%, and 0%, respectively (P <.0001). At multivariate analysis, the N ratio was the best single independent prognostic factor (P =.000). CONCLUSIONS After R0 resection for gastric cancer, the N ratio is a potent prognostic factor. It should therefore be considered in the clinical decision making process.
