Bottom Line: In the case of an early cancer, curative treatment can be achieved through a simple and minimally invasive laparoscopic cholecystectomy.We attempted to predict early cancer occurrence among polypoid lesions of the gallbladder using the simplest standard, size.Although there are some limitations, size can be a simple and easy way to evaluate polypoid lesions of the gallbladder.

ABSTRACT

Backgrounds/aims: Recent advances in ultrasonography have contributed to the early detection of gallbladder cancer. We attempted to predict the progression of the disease by comparing the sizes of polypoid lesions, and we suggest that the size of the lesion would be a useful guideline to determine an appropriate primary surgical approach for polypoid lesions of the gallbladder.

Methods: We have retrospectively analyzed 253 patients that, during the operation period from January 2009 to December 2011, had had ultrasonographically detected gallbladder polypoid lesions, and who underwent cholecystectomy at Ulsan university hospital. We have analyzed the demographic data of the patients, the preoperative size of polypoid lesions, and pathologic findings.

Results: Of a total of 253 patients, 235 patients had benign lesions, and 18 patients had malignant lesions. Among the malignant polyp patients, 11 had pT1 cancer, 6 had pT2 cancer, and 1 had pT3 cancer. The average size of polypoid lesions was 9.1±3.1 mm and that of malignant lesions was 28.2±16.4 mm. The receiver operating characteristic (ROC) curve of the benign and malignant groups shows that 14.5 mm is the optimal point of prediction of the malignancy. Of a total of 18 patients of GB cancer, 11 had pT1 and the average size of their polypoid lesions was 20.5±5.8 mm 7 had pT2 with a size of 39.1±20.7 mm. ROC curve analysis of the pT1 and pT2 groups shows that 27 mm would be the optimal point to predict T2 and above cancer.

Conclusions: In the case of an early cancer, curative treatment can be achieved through a simple and minimally invasive laparoscopic cholecystectomy. We attempted to predict early cancer occurrence among polypoid lesions of the gallbladder using the simplest standard, size. Although there are some limitations, size can be a simple and easy way to evaluate polypoid lesions of the gallbladder.

Figure 1: ROC curve of the correlation between malignant and benign lesions based on data in Table 2. 14.5 mm is the optimal point to predict malignancy.

Mentions: Of the total 253 patients with PLGs, benign lesions were present in 235 patients, and the average size of the GB polyps was 9.1±3.1 mm. Malignancy was found in 18 patients and the average polyp size was 28.2±16.4 mm. There is a statically significant difference in average polyp sizes of the benign and malignant groups (p<0.001). A ROC curve shows 14.5 mm is the optimal point to predict the malignancy (Fig. 1) (Table 2).
