Can we do better than 'incidental' gallbladder cancer?

Area of Science:

• Oncology
• Surgical Pathology
• Diagnostic Imaging

Background:

• Incidental gallbladder cancer is diagnosed after cholecystectomy for presumed benign disease.
• Concerns exist regarding missed diagnoses on preoperative imaging.
• The current definition may obscure cases that were potentially detectable.

Purpose of the Study:

• To evaluate whether some 'incidental' gallbladder cancers were potentially or suspiciously detectable preoperatively.
• To introduce new terminology to better classify these cases.
• To improve surgical management strategies for gallbladder cancer.

Main Methods:

• Review of cases diagnosed with incidental gallbladder cancer.
• Analysis of preoperative imaging findings.
• Clinical case review and discussion of diagnostic criteria.

Main Results:

• A subset of 'incidental' gallbladder cancers may have shown suspicious signs on preoperative imaging.
• Failure to adequately heed imaging findings can lead to suboptimal initial surgery.
• Intraoperative frozen section and conversion to open radical cholecystectomy are recommended for suspicious cases.

Conclusions:

• The terms 'potential' gallbladder cancer and 'suspicious' gallbladder cancer are proposed.
• These new classifications aim to improve the identification and management of gallbladder malignancies.
• Implementing these terms can ensure appropriate surgical procedures are performed when indicated.
