The authors compared survival and identify prognostic factors after resection for invasive IPMN versus stage‐matched PAC. 2017-03-15 WHO 2010 classification, IPMN is classified as IPMN with low- or intermediate-grade dys-plasia, IPMN with high-grade dysplasia, and IPMN with an associated invasive carcinoma (IPMC). IPMC means transformation of intra-ductal papillary mucinous neoplasm to … Invasive IPMN developed more recurrences and had worse survival than LGD or HGD, indicating the need for more efficient postoperative treatment strategies. Patients with LGD and HGD also need regular follow-up for recurrence after 5 years. Malignant margins need additional resection to achieve negat …. 2021-01-13 IPMN and invasive IPMN IPMN lesions were categorized as non-invasive IPMN and invasive IPMN by the WHO classification. There were 29 non-invasive IPMNs (80.6%) and 7 invasive IPMNs (19.4%).

Non-invasive progression was defined as a new IPMN, increased main pancreatic duct (MPD) size, and increased size of an existing lesion (5 mm compared to preoperative imaging).

Clinicopathologic features and long-term outcome of 32 patients with invasive IPMN were retrospectively evaluated and compared with those of 332 patients with pancreatic ductal adenocarcinoma. Results: Asymptomatic patients were more frequently observed in the group of invasive IPMN than ductal adenocarcinoma (28% vs 11%, P = 0.013). The distribution of stages of invasive IPMN was as follows

Malignant margins need additional resection to achieve negat … Gastric type IPMN: cells resemble gastric foveolae, intestinal metaplasia may be seen, usually with low grade dysplasia and branch duct IPMN; if associated invasive carcinoma present, typically ductal (tubular) adenocarcinoma (Ann Surg 2016;263:162, Virchows Arch 2005;447:794, Bosman: WHO Classification of Tumours of the Digestive System, 4th The efficacy of adjuvant therapy for pancreatic invasive intraductal papillary mucinous neoplasm (IPMN). Cancer 2016; 122:521.

Non-invasive progression was defined as a new IPMN, increased main pancreatic duct (MPD) size, and increased size of an existing lesion (5 mm compared to preoperative imaging). Invasive progression was defined as development of invasive cancer in the remnant pancreas or metastatic disease.

다고 하였다. 따라서 IPMN의 invasive type은 병리학적으로 개별적인 개념보다는 췌관선암의 일부라는 것이 받아들여져 2004년 병리학자들의 consensus에서는 기존에 invasive IPMN 이란 용어 대신에 IPMN with invasive carcinoma라는 용어, 즉 췌장암과 병발한 췌관내유두상점액종 Most important, 37% (7/19 patients) had no CT findings of an invasive malignancy according to the Sendai criteria (i.e., cysts ≥ 3 cm in the axial plane, main pancreatic ductal dilatation ≥ 6 mm, or mural nodularity within a cyst) but were found to have an IPMN with either high-grade dysplasia or invasive … 2016-11-04 Extrapancreatic recurrence from non-invasive IPMN is thought to be rare [10,11,14,[19][20][21][22], although metastatic recurrence of invasive IPMN to extrapancreatic organs was reported at a high CONCLUSIONS: Invasive IPMN appears to be more indolent than conven-tional PDAC. Adjuvant therapy is associated with improved OS compared with SA in patients with invasive IPMN, especially for those with higher stage disease, positive lymph nodes, positive margins, or poorly differentiated tumors.

12 2020-08-17 Invasive IPMN recurred in 45% of cases, whereas noninvasive in only 9% and later (P < 0.001), but patterns depended on IPMN subtypes. Only 9 patients required reoperation for recurrence, with good long-term outcome particularly for oncocytic IPMNs.

These results suggested that a cut-off level for the MIB -1 labeling index should be set to 15.5% to 2020-10-01 2011-10-15 The efficacy of adjuvant therapy for invasive IPMN is not well defined. Treatment decisions are often extrapolated from studies in PDAC where randomized trials have generated beneficial results (11-13).
