BACKGROUND
Surgical resection is the treatment of choice of intraductal papillary mucinous neoplasm (IPMN) of the pancreas. However, the benefit of clearing resection margin is still controversial.
METHODS
We reviewed 281 surgically resected cases of IPMN. The recurrences were compared according to the histologic grade (benign or borderline IPMN, malignant noninvasive IPMN, invasive carcinoma) and size (pancreatic intraepithelial neoplasia, PanIN, less than 0.5 cm in the long axis; and IPMN, greater than or equal to 0.5 cm) of the residual lesions at the resection margin.
RESULTS
Sixty cases (21.4%) were invasive carcinoma, and 221 (78.6%) noninvasive cases included 87 (31.0%) benign, 107 (38.1%) borderline and 11 (3.9%) malignant noninvasive IPMN cases. In noninvasive IPMN, increased recurrence in patients with five or more years of follow-up was only related to the involvement of resection margin by severe dysplasia. The recurrence of invasive carcinoma was high (27.3%) even when the resection margin was clear, and was not related to the grade or size of residual tumors at the resection margin.
CONCLUSIONS
Invasiveness is a strong risk factor for recurrence in IPMN regardless of the status of the resection margin. However, in noninvasive IPMN, histologic grading of residual lesions at the resection margin predicts local recurrence.

Abstract PDF

BACKGROUND
Epithelial tumor cells with a CD44(+)/CD24(-/low) immunoprofile may have the ability to cause breast cancer. We studied these cells and their clinicopathological significance.
METHODS
The clinicopathologic findings of 100 invasive ductal carcinoma (IDC) cases and 45 ductal carcinoma in situ (DCIS) cases were reviewed. CD44(+)/CD24(-/low) tumor cells were identified by immunohistochemistry, and their clinicopathological implications in IDC and DCIS were analyzed.
RESULTS
IDC with a high prevalence of CD44(+)/CD24(-/low) tumor cells was significantly associated with larger mass, higher grade, estrogen receptor (ER) negativity, and tumor cells with a higher frequency of metastasis. The proportion of CD44(+)/CD24(-/low) tumor cells in IDC, and its DCIS components was not significantly different, whereas the proportion of CD44(+)/CD24(-/low) tumor cells was higher in DCIS than in the DCIS component of IDC (p < 0.001).
CONCLUSIONS
IDC with a high prevalence of CD44(+)/CD24(-/low) tumor cells might correlate with aggressive features, such as ER and higher grades. Moreover, the proportion of CD44(+)/CD24(-/low) tumor cells in the DCIS components of IDC and DCIS might harbor different biology, which may lead to differences in cancer progression and early carcinogenesis.
