“…The reported accuracy of preoperative depth diagnosis of M-cancer varies from 69.2% to 92.2% [45][46][47][48][49][50][51][52][53], which is consistent with the range in the present results (67%-89.9%). The presence of ulcer fibrosis in the lesion is well known to hamper diagnosis [51][52][53][54], but we did not collect data on ulceration in this study. A discrepancy between macroscopic (intraoperative) and histological (postoperative) diagnosis of node involvement has been reported [55][56][57][58][59].…”

“…To date, EUS imaging can be performed with echoendoscopes or with the use of ultrasound catheters or 'miniature probes' which are passed through standard endoscopes. These miniature probes can provide ultra-high-frequency imaging (12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30), compared to echoendoscopes (5-12 MHz). Higher frequency yields higher resolution of the tumor at the expense of depth of penetration, thus limiting nodal examination [1,2]; thus, a higher frequency probe may provide better evaluation of a T1/T2 cancer, while a lower frequency probe may be more accurate in predicting nodal involvement.…”

“…Fifteen studies [7, 17, 19, 20, 22-24, 26, 29-32, 34-36] used combinations of frequencies of B12 MHz and six studies [18,25,27,28,33,37] used combinations of frequencies ranging from 5 to 20 MHz. It was not feasible to construct a 2 9 2 table to investigate transducer frequencies as source of heterogeneity.…”

Background Accurate preoperative staging is important in determining the appropriate treatment of gastric cancer. Recently, endoscopic ultrasound (EUS) has been introduced as a staging modality. However, reported test characteristics for EUS in gastric cancer vary. Our purpose in this study was to identify, synthesize, and evaluate findings from all articles on the performance of EUS in the preoperative staging of gastric cancer. Methods Electronic literature searches were conducted using Medline, Embase, and the Cochrane Central Register of Controlled Trials from 1 January 1998 to 1 December 2009. All search titles and abstracts were independently rated for relevance by a minimum of two reviewers. Metaanalysis for the performance of EUS was analyzed by calculating agreement (Kappa statistic), and pooled estimates of accuracy, sensitivity, and specificity for all EUS examinations, using histopathology as the reference standard. Subgroup analyses were also performed. Results Twenty-two articles met our inclusion criteria and were included in the review. EUS pooled accuracy for T staging was 75% with a moderate Kappa (0.52). EUS was most accurate for T3 disease, followed by T4, T1, and T2. EUS pooled accuracy for N staging was 64%, sensitivity was 74%, and specificity was 80%. There was significant heterogeneity between the included studies. Subgroup analyses found that annual EUS volume was not associated with EUS T and N staging accuracy (P = 0.836, 0.99, respectively). Conclusion EUS is a moderately accurate technique that seems to describe advanced T stage (T3 and T4) better than N or less advanced T stage. Stratifying by EUS annual volume did not affect EUS performance in staging gastric cancer.

Introduction: the only way of improving prognosis and survival in gastrointestinal cancer is early diagnosis, with intramucosal localization as confirmed by endoscopic ultrasonography (EUS) or 20-MHz miniprobes (MPs) (T1) being most appropriate. Endoscopic mucosal resection (EMR) has proven effective in the treatment of this sort of lesions.Patients and method: in a group (18 cases) with 15 cases of superficial gastrointestinal cancer and 3 cases of severe gastric dysplasia, 9 cases (3 esophageal, 4 gastric, 2 rectal) underwent a classic EMR following EUS or a 7.5-and 20-MHz miniprobe exploration.Results: ultrasonographic studies showed a T1 in all but one esophageal case (Tis), and in both gastric dysplasias, with no changed layer structure being demonstrated in the latter (T0).No complications arose with classic EMR, and all 9 patients are alive and free from local or metastatic recurrence, except for one esophageal case, which recurred distally to the esophageal lesion (metachronous).Conclusions: echoendoscopically-assisted EMR is a safe, effective technique in the endoscopic management of superficial gastrointestinal (esophageal, gastric, colorectal) cancer. Recurrence most likely depends upon cancer multiplicity.Key words: Superficial cancer (early cancer). Endoscopic ultrasonography. High-frequency miniprobes.
