The results for 162 patients who underwent curative gastrectomy for gastric cancer from January 1988 to June 1994 were analysed statistically with special reference to the effect of lymph node dissection. Median survival was 69.3 months and the overall cumulative 5-year survival rate was 50.2 (95 per cent confidence interval (c.i.) 41.6-58.1) per cent. By univariate analysis age, histology, depth of tumour invasion, node involvement, number of metastatic lymph nodes and type of lymphadenectomy were found to be significant factors related to survival time. Multivariate analysis with the Cox model and stratified for tumour node metastasis stage revealed that only the number of metastatic nodes (P = 0.04) and the extent of lymphadenectomy (P = 0.003) affected survival independently. With respect to D1 lymphadenectomy, the relative risk associated with D2 and D4 lymphadenectomy was respectively 0.61 (95 per cent c.i. 0.34-1.10) and 0.26 (95 per cent c.i. 0.12-0.60). The 5-year survival rate was 28 per cent for patients who had a D1 dissection, 63 per cent for those who had D2 and 68 per cent for those who had D4. These results suggest that extended lymphadenectomy (D2) and especially superextended lymphadenectomy (D4) can improve survival in patients with gastric cancer. 相似文献

In this retrospective study, 652 patients who had curative resections for gastric cancer from 1977 to 1991 were reviewed to evaluate improvements in gastric cancer surgery and the influence of the extent of lymphadenectomy on survival. The patients were grouped into three time periods: 1977 to 1981, 1982 to 1986 and 1987 to 1991. The percentage of patients with early gastric cancer increased from 17.7% during 1977 to 1981, to 24.3% during 1987 to 1991. The average number of dissected lymph nodes was 7.5 +/- 8.1 during 1977 to 1981 and 16.4 +/- 10.3 during 1987 to 1991, when more radical lymphadenectomy was adopted. Total gastrectomies increased from 10.9% to 25.9% in the same time periods while combined visceral resections increased from 26.7% to 38.1%. Operative mortality decreased from 5.0% to 1.7%. The overall 5-year survival rate increased from 34.8% to 59.4%. In subgroup analysis, significant improvement of the 5-year survival rate was noted in the following groups: patients with stage I, II and III tumors but not stage IV; both proximal and distally located tumors; tumors with or without lymph node metastases; T1 and T2 but not in T3 and T4 (cancer invasion beyond the serosa). The decreased surgical mortality in recent years suggests that curative resection with extensive lymph node dissection can now be safely performed. Radical gastrectomy with extended lymphadenectomy may be adopted in gastric cancer resection for better control of regional disease. 相似文献

BACKGROUND/AIMS: The present study was carried out in order to examine the outcome of resection in cases of gastric cancer with distant metastases. METHODOLOGY: The survival rates of two hundred and eighty-one patients who had undergone resection for primary carcinomas of the stomach, and who had distant metastases according to the TNM classification, were studied. RESULTS: The 5-year survival rates for patients with metastasis to the peritoneum or group 3 nodes were 8.9% and 15.3% respectively and were significantly higher than the survival rates for patients with metastasis to the liver (0%), to group 4 nodes (2.2%) or to more than one site among the liver, lymph nodes and peritoneum (3.5%). Moreover, the 5-year survival rates for patients with metastasis to the peritoneum and N3 nodes increased significantly to 29.4% and 24.2%, respectively, when curative surgery was performed. CONCLUSIONS: The findings of the present study suggests that metastases to the adjacent peritoneum or group 3 nodes have a greater chance of being cured using radical surgery, and that gastrectomy with extended lymphadenectomy (D2-D3) may be used for advanced gastric cancer if there is no gross evidence of metastasis to the distant peritoneum, liver or group 4 nodes. 相似文献

One-hundred thirty-one primary hepatic resection for colorectal secondary tumors were performed at Rush-Presbyterian-St. Luke's Medical Center between 1975 and 1993. Perioperative mortality occurred in five patients (3.8%). Twenty-three patients had minor morbidities (18%); major morbidity occurred only in the five patients who died. Curative resections were performed in 107 patients. Overall actuarial survival at 2, 3, and 5 years was 62, 42, and 25 per cent, respectively. Patients with extrahepatic disease (5-year survival, 0% vs 27%; P = 0.049) and positive resection margins (0% vs 30%; P < 0.001) had significantly poorer survival. Among the curative resections, patients who had metachronous hepatic resections did significantly better than those who underwent synchronous colon and hepatic resections (35% vs 13%; P = 0.002). This survival benefit persisted when comparison was restricted to patients with synchronous metastases. Age, sex, race, number of lesions, site of colon primary resection, blood transfusion, disease-free interval, and extent of resection had no effect on survival. All patients who are acceptable surgical risks with potentially resectable metastatic colorectal cancer confined to the liver should undergo exploration. Assessment of resectability should include intraoperative ultrasound in all patients to maximize the probability of tumor clearance. 相似文献

A 74-year-old man was diagnosed by preoperative X-ray and endoscopy with biopsy as having type 2 advanced gastric carcinoma (poorly differentiated adenocarcinoma) in the antrum. CT scan revealed swelling of the paraaortic lymph nodes, which was considered to be metastasis from the gastric carcinoma. As the cancer was judged to be stage IV and too advanced for a curative surgical resection, a neoadjuvant chemotherapy was initiated. One course of the regimen consisted of 10 mg of CDDP (day 1-5, drip) and 300 mg of UFT (day 1-7, oral), and the patient underwent the regimen three times in succession. After the chemotherapy, the swelling of para-aortic lymph nodes disappeared on CT scan. A distal gastrectomy with D2 lymph nodes dissection and sampling of the para-aortic lymph nodes was performed. Histopathological examination revealed that the cancer cells had completely vanished both in the primary tumor and lymph nodes. The effect of this neoadjuvant chemotherapy was judged to be Grade 3 histopathologically. 相似文献

Although lymph node metastasis is a major prognostic factor in gastric cancer, the optimal extent of lymph node dissection still remains a subject of debate. The influence of extended D2 lymphadenectomy on morbidity and long-term survival is controversial. Reports from many Japanese and some Western institutions show similar morbidity and mortality rates for both limited D1 and extended D2 resections. However, the four available randomised trials show a significant increase in operative morbidity and mortality after a D2 resection. The authors of these trials believe that distal pancreaticosplenectomy is responsible for this increased morbidity and mortality and not the lymphadenectomy itself. Retrospective and prospective non-randomised studies show superior stage (II/IIIA) specific survival rates after D2 resections. However, these studies did not eliminate stage migration and randomised trials failed to show any survival advantage in favour of the D2 resection. Current data suggest that D2 resection is beneficial to the subgroup of patients with N1 or N2 disease undergoing potentially curative resection. However, Western studies that support D2 resection, fail to show any survival advantage for D2 resection in N2 patients, reporting a benefit only to N0 or N1 patients. In contrast, Japanese series report a large number of N2 long-term survivors. The question as to the possible beneficial effect of extended lymphadenectomy in gastric cancer is difficult and complex. D2 resection increases the potentially curative resection rate, at least in N2 patients, achieves a better locoregional tumour control and provides the only chance for cure among N2 patients since adjuvant treatment in gastric carcinoma has not yet been proved effective. However, all randomised comparisons warn of an increased risk after D2 resection. By avoiding pancreaticosplenectomy, however, the morbidity can be within acceptable limits. D2 gastrectomy seems to be the most attractive procedure in the surgical management of gastric cancer. 相似文献

Early or superficial gastric cancer identifies a lesion that is confined to the mucosa or submucosa layer and that even in the presence of lymph nodes metastasis can be successfully treated with resection and lymph node dissection. In presence of cancer that invades the submucosa the incidence of N2 metastasis raises to 3-5%, and even though a D2 procedure is indicated as the postoperative mortality is similar to D1 procedure. Early gastric cancer of the mid portion of the stomach can be treated with a distal D2 pylorus preserving gastrectomy that has the advantage to reduce the incidence of dumping syndrome; this result can be achieved with a complete dissection of the infrapyloric nodes preservng part of the suprapyloric nodes to spare the right gastric artery. Endoscopic mucosal resection is another therapeutic option available in presence of a mucosal gastric cancer less than 2 cm, well differentiated without ulceration; among 50 cases treated so far, 32 cases were completed resected and they are free of disease up to now. The main risks of this procedure are hemorrhage (5%) and perforation (6.4%). 相似文献

A total of 590 exocrine pancreatic cancers of the body or tail of the pancreas, operated on between January 1982 and December 1988, were analysed. There were 128 pancreatic resections (group 1), 164 palliative bypasses (group 2) and 293 exploratory laparotomies which included 74 splanchnicectomies (group 3). The mortality rate was lower in group 1 (9 per cent) than in group 2 (19 per cent) (P = 0.012). The mortality rate exceeded 40 per cent in groups 1 and 2 for patients aged more than 70 years with pre-existing organ failure. The morbidity rate was 32 per cent in group 1 and 29 per cent in group 2. Patients with metastases had a median survival of 3.4 months, whatever the operative treatment. In the presence of lymph node involvement there was no significant difference in survival between groups 1 and 2. Patients with no metastases and no lymph node involvement had 1- and 3-year survival rates of 38 and 12 per cent respectively after pancreatic resection. Only patients with a small tumour (< or = 4 cm), no lymph node involvement and no metastases achieved a significantly better survival after resection (P = 0.049). Curative resection should be reserved for a small tumour confined to the pancreas. Fewer than 10 per cent of patients will be suitable for surgery. For the other cases, resection must be considered as a palliative procedure without a significant improvement in survival. It seems justified to limit palliative surgery to candidates for digestive bypass and to use non-surgical palliation for the remainder. 相似文献

The "curative" treatment of gastric carcinoma includes the complete removal of the tumour and of the nodes involved without any macroscopic residual of disease (RO). Out of 326 patients with gastric cancer observed, a series of 114 consecutive patients underwent surgical resection (total gastrectomy or subtotal distal gastrectomy) with D2 or D3 lymphadenectomy. Overall operative mortality was 5.3%. Since 1988 no postoperative death occurred. Overall morbidity was 15.8%, specific morbidity 10.5%, reduced after 1988 to 6.6%. No significant differences in operative mortality and need of blood transfusions were recorded between D2 and D3 lymphadenectomy. Overall 5-year survival was 32%. Univariate and multivariate analysis showed that only T and N stages are significant prognostic factors, whereas tumour location, total or subtotal gastrectomy in antral cancers, extent of lymphadenectomy (D2 vs D3) and histology were not significantly related to survival. Since most studies have clearly shown that T and N stages are the most important prognostic factors in gastric cancer, the present aim should be to plan the extent of surgical resection according to the T and N stages characteristics of the neoplasm. 相似文献

BACKGROUND: The therapy for early gastric cancer (endoscopy, gastric resection, D1/2 dissection) is controversial. MATERIALS AND METHODS: In a retrospective study (4/86-12/95) we analyzed the prognosis of 57 early gastric cancer patients with respect to pathological findings and surgical therapy. RESULTS: The R0 resection rate was 100%. In 7% multifocal tumor growth was seen. The 5-year survival rate was 70%. LN-metastases were found in 12% of all cases, more often in pT1b than in pT1 a tumors (17 vs 9%) and more often in large carcinomas than in small carcinomas (> 1000 mm2: 27%; < 300 mm2: 0%). Long-term survival was significantly better in pN0 patients than in patients with LN metastasis (P = 0.020). CONCLUSION: Prognosis of early gastric cancer after curative resection is good. 相似文献

Between September 1985 and December 1994, 322 patients with oesophageal cancer were treated. Of the 190 patients who underwent operation, 173 had an oesophageal resection; in 124 this was performed as an abdominothoracic resection and in 49 by the transhiatal approach. The assessment of radicality after histological examination revealed a curative (R0) resection in 121 patients (70 per cent) and a palliative (R1-R2) resection in 52 (30 per cent). Prognosis was correlated with the extent of mediastinal lymph node dissection. In 77 patients with stage pT1-3 pN0-1 pM0 the 5-year survival rate was 40 per cent after abdominothoracic resection with two-field lymph node dissection and zero after transhiatal resection (P = 0.01). The authors propose a differentiated surgical approach involving abdominothoracic resection with two-field lymph node dissection for patients with limited tumours (pT1-3 pN0-1 M0) if the operative risk is tolerable. Transhiatal resection appears to be effective only in patients with early tumours (Union Internacional Contra la Cancrum stage 0). 相似文献

PURPOSE: To investigate whether pancreas preservation together with a strict quality-control system could ameliorate the outcome of D2 resections for gastric cancer in Western patients. PATIENTS AND METHODS: Italian patients with potentially curable proven adenocarcinoma of the stomach were registered from nine general and/or university hospitals in the area of Turin, Northern Italy. The study was performed according to the guidelines of the Japanese Research Society for Gastric Cancer (JRSGC). A strict quality-control system was guaranteed by a supervising surgeon of the reference center, who had stayed at the National Cancer Center Hospital, Tokyo, to learn the standard D2 gastrectomy. The standard procedure entailed removal of the level 1 and 2 lymph nodes. During total gastrectomy, the pancreas was preserved according to the Maruyama technique. RESULTS: Between May 1994 and December 1996, 191 eligible patients were entered onto the study. The mean number of lymph nodes removed was 39. The overall morbidity rate was 20.9%. Surgical complications were observed in 16.7% of patients. Reoperation was necessary in six patients and was always successful. The overall hospital mortality rate was 3.1%; it was higher after total gastrectomy (7.46%) than after distal gastrectomy (0.8%). The average length of hospital stay was 17 days. CONCLUSION: Given that postoperative morbidity and mortality rates are favorably comparable with those reported after the Western standard gastrectomy, the more extensive Japanese procedure with pancreas preservation can be regarded as a safe radical treatment of gastric cancer for selected Western patients treated in experienced centers. 相似文献

In a controlled study the practicability, tightness of the anastomosis and complications in the p.o. period were analyzed in a total 94 colon and rectum anastomoses by making use of the SPTU-model. 28% of the patients operated in this way were more than 70 years old, the average age came up to 63.3 years. The incidence of anastomotic leakage after low anterior resection was 24% and 5.5% after high anterior resection. 17 per cent of the patients suffered from complications during the postoperative period and 2 patients (2.1 per cent) came to death. The results of 36 high and 58 low anterior resections justify the further use of the SPTU auto-suture apparatus. 相似文献

BACKGROUND: CH-40 is a suspension of activated carbon particles that was developed in Japan to carry anticancer drugs to regional nodes and peritoneal seedings of gastric cancer. METHODS: Forty-five consecutive patients who had surgical resection and D2 lymph node dissection for gastric cancer over a 2-year period were randomly assigned to preoperative endoscopic submucosal injection of CH-40 (group A) or no staining (group B). A total of 21 patients in group A and 24 in group B were available for analysis. RESULTS: The number of resected nodes per patient was significantly higher (t = 6.06; 40 df; P < .0001) in group A (mean+/-S.E. = 35.3+/-1.24) than in group B (mean+/-S.E. = 25.5+/-1.02). The rate of metastatic nodes resected was significantly higher (chi2 = 6.903 ; 1 df; P = .009) in stained (22.5%) than in non-stained (14.7%) nodes of group A and also (chi2 = 6.906; 1 df; P = .009) in stained nodes of group A than in group B (15.8%). CONCLUSIONS: Preoperative endoscopic vital staining with CH-40 proved to be rapid, safe, and effective in all cases in this series. Its use allowed surgeons to resect a higher number of lymph nodes. and to identify and examine more metastatic nodes. It also permitted identification of nodal micrometastases on routine histopathologic examination. 相似文献

Between 1982 and 1991, 112 patients were treated for gastric cancer at Harstad Hospital in Northern Norway. Early gastric cancer accounted for 20% of all the adenocarcinomas (110), which is high compared with figures from other western studies. The role of endoscopy for detecting early gastric cancer is discussed. The five year survival rate after radical surgery was found to be significantly higher for patients with early gastric cancer than for patients who underwent curative surgery for either infiltrative or regional cancer. For patients with a tumour that had invaded the regional lymph nodes the five year survival rate was only 10%. This result can be improved by more extended lymph node dissection. The perioperative mortality rate (8%) was usually a result of severe cancer cachexia or underlying cardial disease, and not anastomotic leakage. The results as regards the cure of early gastric cancer are comparable with those described in other studies. 相似文献

The medical records of 267 patients who had liver tumors, primary and metastatic, from 1988 to 1995 were retrospectively reviewed. Two hundred thirteen patients (80%) had metastatic disease, and 54 patients (20%) had primary liver disease. Their clinical manifestations and laboratory values were evaluated as factors predictive of diagnosis and survival. There was a significant increase in the occurrence of upper abdominal pain, weight loss, extrahepatic symptoms due to the metastatic origin, and hepatomegaly. Metastases from colorectal primary lesions were synchronous in 34 patients and metachronous in 31 patients. Stomach, lung, and pancreatic primaries were more commonly synchronous. Breast metastases were more commonly metachronous. Elevated serum glutamic-oxaloecetic transaminase and alkaline phosphatase and decreased albumin were the most common liver test abnormalities at diagnosis. Carcinoembryonic antigen values were elevated in the majority of colon cancer patients. Eighty-one percent of patients with primary liver cancer had elevated levels of alpha-fetoprotein, 40 per cent were seropositive for hepatitis B, and 23 per cent were seropositive for hepatitis C. Seventy-nine patients (30%) underwent surgery for their cancer, 37 (47%) had resections, 38 (48%) were unresectable, and 4 (5%) underwent liver transplantation. The patients who underwent surgery had a 32 per cent 5-year survival rate compared to a 0 per cent 5-year survival in the patients who did not have surgery (p = 0.0001). The patients who had resections had a better survival rate than those deemed unresectable at surgery (62% versus 0% at 5-years with p = 0.0008). The perioperative morbidity rate was 16 per cent, with lobectomies having the best rate and trisegmentectomies having the worst. Perioperative mortality rate was zero for all liver resections. Hepatic resection and, in selected patients, liver transplantation are the only two available therapeutic modalities that produce long-term survival with a possible cure in patients with primary and metastatic liver tumor. 相似文献

To understand the prevalence of axillary node metastasis and survival of patients with T1a and T1b breast cancers, we reviewed the experience at a large community hospital. All patients in the William Beaumont Hospital tumor registry with breast cancer treated between January 1983 and November 1995 were evaluated for tumor size, age, cell type, and the presence or absence of axillary node disease. Long-term survival was evaluated in patients treated between 1983 and 1992. The patients were defined as premenopausal or postmenopausal based on age (49 years or less, premenopausal; 50 years or greater, postmenopausal). Of the 4590 patients treated for breast cancer from 1983 to 1995, 915 had tumors 1.0 cm or less in size. Of 181 patients who had T1a cancer, 27 were premenopausal, and 154 were postmenopausal. Twenty-three premenopausal patients had axillary lymph nodes examined, two (8.7%) had histologically positive lymph nodes. Of 118 postmenopausal patients who had axillary nodes examined, six (5.1%) had positive lymph nodes. In those with T1b tumors, 130 patients were premenopausal; 604 patients were postmenopausal. Of these, 119 premenopausal patients had axillary nodes examined, and 29 (24.4%) had positive lymph nodes. Of 464 postmenopausal patients who had axillary nodes examined, 66 (14.2%) had positive nodes. The overall, disease-free, and tumor-specific survival rates for patients with T1a tumors were 93.8, 87.5, and 93.8 per cent (premenopausal) and 86.2, 95.4, and 95.4 per cent (postmenopausal), respectively. These survival rates for patients with T1b tumors were 87.8, 87.8, and 91.1 per cent (premenopausal) and 82.9, 88.5, and 92.9 per cent (postmenopausal), respectively. Premenopausal T1b patients had a higher rate of nodal involvement than postmenopausal T1b patients (P = 0.011). Postmenopausal T1b patients had a higher nodal metastasis rate than postmenopausal T1a patients (P = 0.01). T1b patients had a higher rate of axillary involvement than did T1a patients (P = 0.0018). Based on the rate of axillary lymph node metastasis and survival statistics, there may be a role for axillary node dissection in select patients with tumors less than 1.0 cm. in size. 相似文献

A retrospective study of 155 patients with submucosal gastric carcinoma compared the clinicopathologic features with mucosal and muscularis proprial gastric carcinoma. Fifty-seven percent of the patients presented with gastrointestinal symptoms, whereas 36.1% had been detected by mass screening. The incidence of curative resection, lymph node metastasis, and complications were 96.1, 20.6, and 14.8%, respectively. Two patients died of sepsis and pulmonary infarction 30 days post-operatively. Five patients died of recurrent gastric cancer 1-5 years postresection. The overall 5-year survival rate was 90.2%. Recurrence patterns, histologic type, lymph node metastasis, lymphatic and venous infiltration, and growth pattern were similar to those of muscularis proprial carcinoma rather than mucosal carcinoma. Therefore, curative gastrectomy with extended lymphadenectomy (D2) may be feasible for submucosal carcinoma of the stomach. 相似文献

Surgeons are aware of the adverse effect that resection-line disease has on anastomotic leakage, perioperative mortality and long-term survival. In an attempt to assess the effect of this knowledge on surgical practice, patients entered into the second British Stomach Cancer Group adjuvant therapy trial were studied. The presence of resection-line disease was compared with the operative stage. Of 555 patients for whom complete data were available, resection-line disease was present in 105 (19 per cent). Of 424 patients undergoing what the surgeon considered to be a potentially curative operation, 55 (13 per cent) had involvement of one or both resection lines, rendering the surgery palliative. Only 9 per cent of patients with stage I-III disease and resection-line involvement survived beyond 5 years, compared with 27 per cent of those with clear lines. Despite knowledge of the adverse effects of resection-line disease, surgeons continue to perform inadequate resections. This demonstrates the need for a more aggressive approach to assessment of resection margins at operation. 相似文献

BACKGROUND/AIMS: Pancreatic cancer has a poor prognosis, which is, in part due, to the unfortunately advanced stage, in which the tumor is diagnosed. Since 1973, we have utilized a unique method of extended radical pancreatectomy, using the translateral retroperitoneal approach (TRA) to facilitate combined portal resection. The advantages of this operation are described herein, for patients with carcinoma of the head of the pancreas. In addition, the problems associated with this operation are discussed. METHODOLOGY: Survival was calculated based on type of resection, degree of invasion of the retroperitoneal tissues, degree of lymph node involvement, and cancer stage. Extensive surgery has been performed for pancreatic carcinoma 216 patients. Of these, 14 patients had carcinoma of the head of the pancreas. There were 58 patients who underwent macroscopically curative resections. RESULTS: Only 39 patients were microscopically curative. Ten of the patients who underwent microscopically curative resections, survived for 5 years (34.0%). There were no statistically significant differences in survival based on tumor size. However, there was a significant difference in survival based on extent of invasion of the anterior capsule of the pancreas, extent of invasion of the retroperitoneal tissue, extent of lymph node involvement, cancer stage, and extent of invasion at the surgical margin of resection. CONCLUSION: The results suggest that extended radical pancreatectomy may be indicated for the treatment of cancer of the head of the pancreas. 相似文献
