Aim To compare feasibility, accuracy, and safety of laparoscopy and laparotomy in surgical staging of early-stage ovarian and
fallopian tubal cancer.
Methods Outcomes of patients with stage I ovarian and fallopian tubal cancer who underwent complete surgical staging at Asan Medical
Center, Korea between 2004 and 2007 were retrospectively evaluated.
Results Nineteen patients were surgically staged through laparoscopy and 33 through laparotomy. There were no between-group differences
in mean age, parity, body mass index, lymph nodes retrieved, or omentum specimen size, nor were there between-group differences
in the percentage of patients who were postmenopausal, those referred for restaging, in the time interval to restaging, in
those upstaged after surgery, or in those with intraoperative tumor rupture. The laparoscopy group had significantly shorter
operating time (221 ± 83 min versus 275 ± 63 min, P = 0.012), less blood loss (240 ± 228 mL versus 568 ± 451 mL, P = 0.005), less transfusion requirement (5.3% versus 30.3%, P = 0.033), faster return of bowel movement (1.3 ± 0.7 days versus 3.6 ± 1.7 days. P < 0.001), and shorter postoperative hospital stay (8.9 ± 6.1 days versus 14.5 ± 5.6 days, P = 0.002) and time interval to adjuvant chemotherapy (12.8 ± 4.9 days versus 17.6 ± 8.3 days, P = 0.049). There were no postoperative complications requiring further management. After a median follow-up time of 17 months
(range 1–44 months), there was no recurrence or death from disease in either group.
Conclusion Laparotomy and laparoscopy showed similar surgical staging adequacy and accuracy, and laparoscopy showed more favorable operative
outcomes. Laparoscopy was safe for early-stage ovarian and fallopian tubal cancer, although follow-up time was relatively
short.

Clinical Impact of Tumour Involvement of the Anastomotic Doughnut in Oesophagogastric Cancer Surgery
K Sillah EA Griffiths SA Pritchard R Swindell CM West R Page IM Welch 《Annals of the Royal College of Surgeons of England》2009,91(3):195-200
INTRODUCTION
Published colorectal cancer surgery data suggest no role for the analysis of the anastomotic doughnuts following anterior resection. The usefulness of routine histological analysis of the upper gastrointestinal doughnut is not clear. Our study assessed the impact of cancer involvement of the doughnut on clinical practice. Factors associated with doughnut involvement and the effect on patients'' survival were also analysed.PATIENTS AND METHODS
The clinicopathological details of 462 patients who underwent potentially curative oesophagogastrectomy for cancer with a stapled anastomosis between 1994 and 2006 in two specialist centres were retrospectively analysed. Univariate, multivariate and survival analyses were carried out.RESULTS
Approximately 5% of doughnuts (22 of 462) were histologically involved with cancer. Microscopic involvement of the proximal resection margin, local lymph node metastasis and lymphatic invasion within the main resected specimen were independently associated with doughnut involvement (all P < 0.05). However, these three factors taken together failed to predict doughnut involvement. Doughnut involvement was an independent adverse prognostic factor for overall survival (P = 0.0013).CONCLUSIONS
In contrast to findings in colorectal surgery, doughnut involvement with cancer appears to have useful prognostic information following oesophagogastrectomy. Routine histological analysis of upper gastrointestinal doughnuts is justified. Doughnut involvement could potentially strengthen the indications for adjuvant therapy in the future. 相似文献5.
目前临床上广泛使用的肺癌分期法是1997年正式提出的,在过去的10年中对规范肺癌的诊治及临床研究起到了重要的作用,但也渐渐显示出其不足之处。2007年国际肺癌研究联合会(IASLC)通过收集100869例肺癌患者的临床资料,就TNM分期与预后之间的相关性做了深入分析,提出了对第7版肺癌TNM分期的修改建议:(1)根据肿瘤大小不同,将原来的T分期分为T1a(肿瘤最大直径≤2cm)、T1b(3cm≥肿瘤最大直径〉2cm)、T2a(5cm≥肿瘤最大直径〉3cm)、T2b(7cm≥肿瘤最大直径〉5cm);(2)将T2c(肿瘤最大直径〉7cm)和原发肺叶内出现转移灶归为T3,将同侧其他肺叶内出现转移灶归为T4;(3)把癌性胸水、心包积液及对侧肺结节转移归为M1a,肺外转移归为M1b。新的版本在国际上将具有更高的权威性和认同度,在今后肺癌的治疗及判断预后上将起到更细致、更精确的指导作用;同时,也为肺癌的研究提供了一个新的起点。 相似文献

Diagnostic Laparoscopy for Primary and Secondary Liver Malignancies: Impact of Improved Imaging and Changed Criteria for Resection 总被引:1,自引:0,他引:1
de Castro SM Tilleman EH Busch OR van Delden OM Laméris JS van Gulik TM Obertop H Gouma DJ 《Annals of surgical oncology》2004,11(5):522-529
Background Diagnostic laparoscopy (DL) combined with laparoscopic ultrasonography (LUS) has previously shown positive results as a staging modality for liver malignancies. Recent improvements in noninvasive diagnostic imaging techniques such as multiphasic spiral computed tomography, together with the policy that bilobar disease or the number of lesions is no longer considered an absolute exclusion criterion for curative resection, could reduce the additional value of DL. This study retrospectively analyzed the efficacy of DL combined with LUS for liver malignancies to assess the effect of improved imaging and changed criteria for resection.Methods All patients with primary or metachronous secondary liver malignancy eligible for resection in 1997 to 2002 were included.Results DL combined with LUS was performed in 84 consecutive patients (56 men and 28 women; mean age, 59 years) with primary (n = 33) or secondary (n = 51) liver malignancies. DL showed unresectability in 13 patients (39%) with primary malignancy. Exploratory laparotomy showed that an additional 5 (25%) of the remaining 20 patients had unresectable disease. DL showed unresectability in 5 patients (12%) with colorectal liver metastasis (n = 43). At laparotomy, another 7 (18%) of the remaining 38 patients had unresectable disease. In five patients (13%) from the latter group, LUS could not be performed because of adhesions from previous surgery.Conclusions DL combined with LUS is an adequate staging modality for primary liver malignancies. For colorectal liver metastasis, more liberal resection criteria, a high failure rate due to adhesions from previous surgery, and better preoperative imaging probably resulted in a lower efficacy. 相似文献

目前胃癌的TNM分期已经成为临床胃癌诊疗的首选参考依据。在国际抗癌联盟(UICC)、国际胃癌协会(IGCA)和美国癌症联合委员会(AJCC)的共同协作推动下,通过对全世界范围内胃癌大数据的收集与分析,于2016年10月颁布了第8版胃癌TNM分期系统。第8版TNM分期系统对食管-胃结合部及贲门癌分期标准的选择做出了明确的定义;同时还在单一分期系统的基础上新增了临床TNM分期(cTNM)和新辅助治疗后分期(ypTNM)。此外,新版的分期系统将N3的两个亚组N3a和N3b作为独立组别纳入到分期系统,还对组织学分级进行了一些调整。总的来说,相比第7版胃癌TNM分期系统,新版的分期系统可以指导临床医生更加合理地制定治疗方案,更加科学地评价治疗效果,更加准确地评估预后。然而,随着临床广泛应用和进一步验证,以及新的预测因子的发现,必将会有新的分期系统替代和完善旧的分期系统。 相似文献

Fewer than 20% of patients with pancreatic cancer have resectable tumours at the time of diagnosis. In two patients with a pancreas neoplasm a laparoscopic staging work-up was performed. Because of the described limitations of laparoscopy, we propose to switch to a hand-assisted procedure. In our opinion the benefits of hand-assisted laparo-scopic surgery, such as safe blunt digital dissection, restoration of tactile feedback and restored proprioception, account for greater accuracy in TNM staging and in the assessment of resectability of pancreatic cancer. 相似文献

Aim: The variability of prognosis of gastric cancer (GC) within a pathological stage necessitates the identification of subgroups of patients with a more aggressive disease. The role of p53 and Ki67 expression in gastric carcinoma is far from being fully established. The aim of the present study was to evaluate the expression of p53 and Ki67 in gastric cancer and correlate the findings with several clinicopathological features and prognosis. Materials and methods: Tissue samples from 93 patients treated by gastric resection for gastric carcinoma between 1996 and 2001 were used. Formalin-fixed paraffin-embedded tumors were studied by immunohistochemistry, using monoclonal antibodies to p53 and Ki67. The results were correlated with clinicopathological features and survival. Results: Stronger expression of p53 was related with tumor size greater than 5 cm and advanced stage. Stronger expression of Ki67 correlated with higher ratio of the number of metastatic lymph nodes to the total number of dissected lymph nodes (metastatic lymph node [MLN] ratio) and advanced stage. Moreover, p53 and Ki67 overexpression, tumor size greater than 5 cm, MLN ratio, depth of invasion, lymph node metastasis, stage III and IV and infiltrative macroscopic appearance were adverse prognostic factors. The levels of p53 and Ki67, the MLN ratio, the tumor size (above 5 cm) and the stage of the disease were identified as independent prognostic factors of survival.Conclusions: In gastric cancer, the expression of p53 and Ki67 provides significant information about prognosis. The routine evaluation of p53 and Ki67 levels could be a useful tool in identification of patient with more aggressive disease and contribute to a better therapeutic approach. 相似文献

Background and Objectives:
Robotic surgery has been advocated for the radical excision of rectal cancer. Most data supporting its use have been reported from European and Asian centers, with a paucity of data from the United States documenting clear advantages of the robotic technique. This study compares the short-term outcome of robotic versus laparoscopic surgery.Methods:
Consecutive patients who underwent laparoscopic (group 1) or robotic (group 2) rectal cancer excision at a single institution over a 2-year period were retrospectively reviewed. The main outcome measures were operative time, blood loss, conversion rates, number of lymph nodes, margin positivity, length of hospital stay, complications, and readmission rates.Results:
Forty-two patients were analyzed. The median operative time was shorter in group 1 than that in group 2 (240 minutes vs 260 minutes, P = .04). No difference was noted in blood loss, transfusion rates, intraoperative complications, or conversion rates. There was no difference in circumferential or distal margin positivity. The median length of stay was shorter in group 1 (5 days vs 6 days, P = .05). The 90-day complication rate was similar in both groups (33% vs 43%, P = .75), but there was a trend toward more anastomotic leaks in group 1 (14% vs 0%, P = .23). Similarly, a non–statistically significant trend toward a higher readmission rate was noted in group 1 (24% vs 5%, P = .18).Conclusion:
Robotic rectal cancer excision yielded a longer operative time and hospital length of stay, although immediate oncologic results were comparable. The need for randomized data is critical to determine whether the added resource utilization in robotic surgery is justifiable. 相似文献18.
