2013-01-01 · The main duct IPMN variant is three times more likely to be invasive than the branch type 8 and is associated with cancer in 60–83%. 11 Current recommendation is therefore to resect all main duct and mixed IPMN variants. 5 The guidelines for branch duct IPMN allow for a more conservative approach since this lesion seems to be associated with a malignancy rate of 6–46%. 5 Therefore

Invasive intraductal mucinous papillary neoplasms (IPMNs) are a heterogenous group of neoplasms, but little is known about the epithelial subtypes of the precursor IPMNs from which these lesions

Although intraductal papillary mucinous neoplasms are benign tumors, they can progress to pancreatic cancer. Although invasive intraductal papillary mucinous neoplasm (IPMN) of the pancreas is thought to be more indolent than sporadic pancreatic adenocarcinoma (PAC), the natural history remains poorly defined. The authors compared survival and identify prognostic factors after resection for invasive IPMN versus stage‐matched PAC. METHODS: Invasive intraductal papillary-mucinous carcinoma (I-IPMC) is a heterogeneous entity with various postoperative outcomes. The aim of this study is to characterize early-stage I-IPMC with nonaggressive characteristics.

Resection is typically recommended for IPMNs with high-grade dysplasia (carcinoma in situ), IPMNs that have progressed to invasive carcinoma (also referred to as invasive IPMN or malignant IPMN), and IPMNs with features concerning for malignancy or that are at high risk for developing malignancy. Intraductal papillary mucinous neoplasm (IPMN) is a type of cyst that is found in the pancreas. These cysts are benign - meaning they are not cancerous to start. Intraductal papillary mucinous neoplasm (IPMN) is a type of tumor that can occur within the cells of the pancreatic duct. IPMN tumors produce mucus, and this mucus can form pancreatic cysts. Although intraductal papillary mucinous neoplasms are benign tumors, they can progress to pancreatic cancer. Invasive IPMN developed more recurrences and had worse survival than LGD or HGD, indicating the need for more efficient postoperative treatment strategies.

These neoplasms are aggressive, and harbor an situ/carcinoma or invasive carcinoma in up to Demographic data, symptoms, type of surgery and type of lesion (branch type, main duct or mixed) were recorded.

Detection of IPMN in the early phases of transformation can permit prompt surgical referral often with positive outcomes . Sohn et al. show a 5-year survival of 77% in non-invasive IPMN and 43% for invasive cancer . Tumour markers have been employed to aid in differentiating between benign and malignant IPMN.

The current treatment strategy for intraductal papillary mucinous neoplasms (IPMNs), based on the international consensus guideline, has been accepted widely. However, reported outcomes after surgical resection for IPMN show that once the tumor progresses to invasive intraductal papillary mucinous carcinoma (IPMC), recurrence is not uncommon.

Invasive IPMN appears to be more indolent than conventional 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.

Results: Of 412 patients with IPMN who underwent pancreatectomy, 98 had invasive carcinoma. Median survival in invasive IPMN was 32 months. Adjuvant treatment did not affect median survival in node-positive or node-negative invasive IPMN.

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%). The mean age of the patients with non-invasive IPMN was 64.4±8.8 years, whereas the mean age of patients with invasive IPMN was 59.9±5.7 years.
