Systemic chemotherapy is the treatment recommended for prolonged survival in cases of metastatic gastric cancer. There have been a number of clinical reports of surgical resection of liver metastasis in selected patients with gastric cancer. Here, we report on a case of treatment of far advanced gastric cancer with synchronous multiple liver metastases with prompt S-1 in combination with fractional cisplatin sandwiched between twostage surgery. Metastases including peritoneal dissemination and extensive lymph node involvement were absent so it was feasible to completely remove all of the macroscopic liver metastases. Each step of the chemotherapy progressed satisfactorily and histological examination after the hepatectomy yielded a pathologically complete response of liver metastases from the gastric cancer. This strategy provides a promising treatment for far advanced gastric cancer with a limited number of synchronous liver metastases. The referral to surgical oncology is a crucial step for the documentation of pathological complete response. 相似文献

The number of early gastric cancer (EGC) cases has been increasing because of improved diagnostic procedures. Applications of function-preserving gastric cancer surgery may therefore also be increasing because of its low incidence of lymph node metastasis, excellent survival rates, and the possibility of less-invasive procedures such as laparoscopic gastrectomy being used in combination. Pylorus-preserving gastrectomy (PPG) with radical lymph node dissection is one such function-preserving procedure that has been applied for EGC, with the indications, limitations, and survival benefits of PPG already reported in several retrospective studies. Laparoscopy-assisted proximal gastrectomy has also been applied for EGC of the upper third of the stomach, although this procedure can be associated with the 2 major problems of reflux esophagitis and carcinoma arising in the gastric stump. In the patient with EGC in the upper third of the stomach, laparoscopy-assisted subtotal gastrectomy with a preserved very small stomach may provide a better quality of life for the patients and fewer postoperative complications. Finally, the laparoscopy endoscopy cooperative surgery procedure combines endoscopic submucosal dissection with laparoscopic gastric wall resection, which prevents excessive resection and deformation of the stomach after surgery and was recently applied for EGC cases without possibility of lymph node metastasis. Function-preserving laparoscopic gastrectomy is recommended for the treatment of EGC if the indication followed by accurate diagnosis is strictly confirmed. Preservation of remnant stomach sometimes causes severe postoperative dysfunctions such as delayed gastric retention in PPG, esophageal reflux in PG, and gastric stump carcinoma in the remnant stomach. Moreover, these techniques present technical difficulties to the surgeon. Although many retrospective studies showed the functional benefit or oncological safety of function-preserving gastrectomy, further prospective studies using large case series are necessary. 相似文献

Background
Postoperative complications such as anastomotic leakage were reported to be a major independent prognostic factor for long-term survival in gastrointestinal malignancies. This study sought to clarify the prognostic significance of postoperative inflammatory complications specifically for patients with gastric cancer.Methods
This study included 1,395 patients who underwent curative resection for gastric cancer from 2005 to 2008. Complications were evaluated according to the Clavien-Dindo classification. Overall survival (OS) and disease-specific mortality (DSM) were compared between complication and no-complication groups. Presence of complications was modeled by the Cox proportional hazard model for OS and the Fine and Gray competing risk regression model for DSM to assess the correlation between complication and prognosis.Results
The median follow-up time was 3.1 years. Two hundred seven patients (14.8 %) had complications of grade 2 or higher. Of 131 patients who died within this period, 87 died of gastric cancer. The 3-year OS in the complication group was 84.1 % compared to 93.1 % in the no-complication group (P < 0.0001). The cumulative incidence of DSM was also significantly worse in patients with complications (P < 0.0001). Multivariate analysis identified the same significant increasing risk of complication for both OS (hazard ratio 1.88; 95 % confidence interval 1.26–2.80) and DSM (hazard ratio 1.90; 95 % confidence interval 1.19–3.02).Conclusions
Postoperative complications that can cause prolonged inflammation have an obvious impact not only on the OS but also on the DSM of patients with gastric cancer even if the tumor is resected curatively. 相似文献5.
Endoscopic Evaluation of Reflux Esophagitis After Proximal Gastrectomy: Comparison Between Esophagogastric Anastomosis and Jejunal Interposition 总被引:1,自引:0,他引:1

BACKGROUND: Although proximal gastrectomy has been performed more as a function-preserving surgery, reflux esophagitis can occur postoperatively, resulting in poor postoperative quality of life. To date, only a few reports have compared the methods of reconstruction performed after proximal gastrectomy, and the method most likely to prevent postoperative reflux esophagitis remains undetermined. METHODS: A retrospective review of 76 patients who underwent proximal gastrectomy with jejunal interposition (JI) or esophagogastrostomy (EG) at the Cancer Institute Hospital between April 1996 and August 2005 was performed. Preoperative characteristics, operative findings, and postoperative gastrointestinal fiberoscopy findings were reviewed and compared between JI and EG patients. Furthermore, we investigated the relationship between the length of interposed segment and operative and postoperative findings. RESULTS: The frequency of grade C or D reflux esophagitis was lower in the JI group than in the EG group (p = 0.001), although the former required a longer operation time (256.5 +/- 10.2 min) than the latter (195.8 +/- 8.2 min; p < 0.001). Other characteristics and postoperative clinical course did not differ between the groups. In the JI group, interposed segments 10 cm or shorter were advantageous in evaluating the remnant stomach when compared with interposed segments longer than 10 cm. No relationship was observed between the length of the interposed segment and clinical findings, except operation time. CONCLUSION: Jejunal interposition helps prevent reflux esophagitis after proximal gastrectomy. The optimal length of the interposed segment is undetermined; however, a length of 10 cm or shorter is preferred for endoscopic evaluation of the remnant stomach. 相似文献

Among patients with negative initial biopsies of the prostate, 51 patients underwent total 59 repeat biopsies at the Department of Urology of Ikeda Municipal Hospital between January 1998 and April 2004. Overall 26 patients (44.1%) were confirmed to have cancer, 22 patients by second repeat biopsy (22/51), four patients by third biopsy (4/7) and none by fourth biopsy (0/1). Clinical parameters (age, PSA, PSA density, PSA velocity) were analyzed for the possibility to predict the pathological outcome. Significant differences between the positive biopsy group and the negative biopsy group were obtained in age, PSA level and prostatic volume. Of the diagnostic evaluations including palpation and imaging studies (DRE, TRUS, MRI), the most powerful predictor for prostate cancer seemed to be the MRI findings, especially in the cases of short-interval repeat biopsy. Biopsies directed at the positive lesion on MRI in addition to systematic prostate biopsies should be useful. 相似文献

Total gastrectomy or proximal gastrectomy is usually performed either as an open procedure or laparoscopically for the treatment
of early gastric cancer (EGC) in the upper stomach. However, quality of life after either total or proximal gastrectomy is
not so satisfactory. The authors report a novel surgical procedure, laparoscopy-assisted subtotal gastrectomy (LAsTG), by
which a very small remnant stomach is preserved, for the surgery of selected EGCs in the upper stomach. Twenty-three patients
with EGC in the upper stomach underwent LAsTG. After lymph node dissection and mobilization of the stomach, the stomach was
transected about 2 cm proximal to the tumor and a very small remnant stomach was preserved. An anvil was inserted transorally
into the remnant stomach by using the OrVil™ system. The reconstruction method was Roux-en-Y, and hemidouble-stapling gastrojejunostomy
with a circular stapler was performed intracorporeally. There were no intraoperative complications or conversions to open
surgery. Mean operation time and blood loss were 266.7 min and 54.6 ml, respectively. The overall incidence of early postoperative
complications was 17.4%, and two patients underwent reoperation because of duodenal stump leakage and stenosis of the Y-anastomosis,
respectively. During the follow-up period, two patients experienced gastrojejunostomy stenosis and both were treated successfully
by endoscopic balloon dilation. LAsTG may be performed in selected patients with EGC in the upper stomach. With the described
method, a very small remnant stomach can be preserved. 相似文献

It has been difficult to improve the prognosis of the type 4 advanced gastric cancer because the peritoneal dissemination develops frequently. In the present study, the therapeutic strategy, an administration of chemotherapy followed by gastrectomy, for the type 4 advanced gastric cancer with positive lavage cytology (CY) was discussed. CY has changed to negative in 3 of 6 cases (50%) at the surgery and in 1 of another 3 cases during the post operative chemotherapy. MST was 1487 days (966-2354 days) in cases with negative CY after pre-operative treatment, while 193 and 395 days in another 2 cases remained in positive CY, respectively. It may be important to perform re-staging laparoscopy with the evaluation of CY after preoperative chemotherapy for the type 4 advanced gastric cancer with positive CY, because the survival was comparatively better in cases with the change from positive CY to negative CY after the treatment. In conclusion, the treatment strategy for the type 4 advanced gastric cancer with positive CY was to administer chemotherapy followed by curative intent surgery for the case with negative CY after pre-operative treatment, while the other regimen of chemotherapy administration for the case with positive CY remained. 相似文献

A rigid contact scope is a recent development of optical instrument which allows observations of the superficial layers of the mucosai epithelium in gynecology and otorhinolaryngology. To assess the evaluation of 25 patients with advanced gastric cancer, whose lesions had been diagnosed to be more than T3 or suspected to have peritoneal deeding, we performed pre operative laparoscope with rigid contact scope. After inspecting a usual laparoscopic observation of the abdominal cavity, serosal exporsure and peritoneal seeding were confirmed. All the patients who had serosal exporsure and cancer cells showed an irregularity of cell distribution with the extent of heterogeneity of the cells with nuclei size and shape. Five patients had peritoneal seeding, and the findings with rigid contact scope showed a similar view to cancer cells which were observed in serosal exposure. The result suggests that this new endoscopic technique enabled a new diagnostic approach in advanced gastric cancer. 相似文献

A 55-year-old woman, underwent a total gastrectomy with super extended lymphadectmy for type 4 gastric cancer 4 years ago, suffered a locoregional recurrence at the esophagojejunostomy. She was given S-1 with cisplatin for a treatment against the recurrent site. Although grade 2 leucocytopenia and grade 3 anorexia were observed, consecutive twenty five courses of the regimen were carried out with a dose modification of anticancer drugs, and home parentenral nutrition system was used for severe anorexia. She has been alive for more than 3 years since the start of the treatment with a good control of locoregional recurrent lesion, and no other apparent metastatic sites were observed. 相似文献
