“…These high re-staging rates support the use of diagnostic laparoscopy (DL) to clarify pre-operative intent. Our review on the use of DL in gastric cancer found that DL changed management in 10-60% of cases [69].…”

Background Surgery is the fundamental curative option for gastric cancer patients. Imaging scans are routinely prescribed in an attempt to stage the disease prior to surgery. Consequently, the correlation between radiology exams and pathology is crucial for appropriate treatment planning. Methods Systematic searches were conducted using Medline, Embase, and the Cochrane Central Register of Controlled Trials from January 1, 1998 to December 1, 2009. We calculated the accuracy, overstaging rate, understaging rate, Kappa statistic, sensitivity, and specificity for abdominal ultrasound (AUS), computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET) with respect to the gold standard (pathology). We also compared the performance of CT by detector number and image type. A meta-analysis was performed. Results For pre-operative T staging MRI scans had better performance accuracy than CT and AUS; CT scanners using C4 detectors and multi-planar reformatted (MPR) images had higher staging performances than scanners with \4 detectors and axial images only. For pre-operative N staging PET had the lowest sensitivity, but the highest specificity among modalities; CT performance did not significantly differ by detector number or addition of MPR images. For pre-operative M staging performance did not significantly differ by modality, detector number, or MPR images. Conclusions The agreement between pre-operative TNM staging by imaging scans and post-operative staging by pathology is not perfect and may affect treatment decisions.

“…Given that the accuracy of ct imaging in detecting M1 disease is 81% 66 , diagnostic laparoscopy could allow patients to avoid a laparotomy in up to 44% of cases of advanced-stage cancer 67 . Guidelines from both the Scottish Intercollegiate Guidelines Network 68 Surgeons 69 suggest diagnostic laparoscopy in patients with clinically suspected T3 and T4 cancers or in those at higher risk for M1 disease, such as those with poorly differentiated cancers and with a higher nodal burden.…”

A systematic review of the accuracy and indications for diagnostic laparoscopy prior to curative-intent resection of gastric cancer

Abstract: Despite evolving preoperative imaging techniques, diagnostic laparoscopy continues to be of substantial value in staging patients with gastric cancer and in avoiding unnecessary laparotomy. The current data support DL for all patients with advanced gastric cancer.
