Outcome of unresected gastric cancer after laparoscopic diagnosis of peritoneal carcinomatosis

Abstract

Laparoscopic staging of gastric cancer can help to avoid unnecessary laparotomies. In patients with peritoneal carcinomatosis diagnosed by laparoscopy, nonsurgical treatment has low morbidity and mortality and permits good symptom relief with no shortening of survival.

Accuracy and clinical relevance of computed tomography scan interpretation of peritoneal cancer index in colorectal cancer peritoneal carcinomatosis: A multi‐institutional study

“…This method involves image co‐registration of both CT and PET scans to produce a single image that depicts the spatial distribution and also demonstrate anatomic accuracy in localizing the site of metabolic activity, hence providing more precise anatomic localization to functional imaging which is lacking in pure PET scans. Alternatively, a minimally invasive approach of diagnostic laparoscopy may be performed to provide direct visualization of the peritoneal cavity 19–21. This technique is useful in assessing patients in whom there is inadequate information or uncertainty in the extent of carcinomatosis.…”

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

“…Early gastric cancers (T1 and T2) were included in ten studies [14, 16-18, 20, 21, 23, 24, 26, 30]. The tumor stage was not defined in seven studies [10,12,13,22,25,27,29]; however, all cases included were considered curative based on preoperative imaging.…”

Depth of tumor invasion and tumor-occupied portions of stomach are predictive factors of intra-abdominal metastasis

“…Kaiser et al . (11-13) also reported similar metastasis detection rates for resectable M0 gastric cancer patients (20.6%, 24.7% and 23.0%, respectively). It is widely accepted that peritoneal dissemination spreads from the tumor to the serosa, but in our 51 DL+ patients, we also found 2 cT2N0 patients who had free cancer cells, 3 cT3N0 patients who had free cancer cells and 2 cT3N0 patients who had visible peritoneal dissemination.…”

“…(14) and Osorio et al . (13) reviewed patients who underwent diagnostic laparoscopy and laparotomy in the same period, respectively, and showed that there was no significant difference in the rate of intra-abdominal metastasis (45.2% vs . 35.5%, P=0.299; 20.6% vs .…”

“…Osorio et al . (13) compared the results of patients who underwent either diagnostic laparoscopy or laparotomy and were not submitted to any additional surgical procedure due to intra-abdominal spread. The patients who underwent diagnostic laparoscopy had a lower morbidity (11.8% vs .…”
