BACKGROUND AND AIM
Intraductal papillary mucinous neoplasm (IPMN)-derived pancreatic ductal adenocarcinoma (PDAC) management is generally extrapolated from pancreatic intraepithelial neoplasia (PanIN)-derived PDAC guidelines. However, these are biologically divergent, and heterogeneity further exists between tubular and colloid subtypes.
METHODS
Consecutive upfront surgery patients with PanIN-derived and IPMN-derived PDAC were retrospectively identified from international centers (2000-2019). One-to-one propensity score matching for clinicopathologic factors generated three cohorts: IPMN-derived versus PanIN-derived PDAC, tubular IPMN-derived versus PanIN-derived PDAC, and tubular versus colloid IPMN-derived PDAC. Overall survival (OS) was compared using Kaplan-Meier and log-rank tests. Multivariable Cox regression determined corresponding hazard ratios (HR) and 95% confidence intervals (95% CI).
RESULTS
The median OS (mOS) in 2350 PanIN-derived and 700 IPMN-derived PDAC patients was 23.0 and 43.1 months (P < 0.001), respectively. PanIN-derived PDAC had worse T-stage, CA19-9, grade, and nodal status. Tubular subtype had worse T-stage, CA19-9, grade, nodal status, and R1 margins, with a mOS of 33.7 versus 94.1 months (P < 0.001) in colloid. Matched (n = 495), PanIN-derived and IPMN-derived PDAC had mOSs of 30.6 and 42.8 months (P < 0.001), respectively. In matched (n = 341) PanIN-derived and tubular IPMN-derived PDAC, mOS remained poorer (27.7 vs 37.4, P < 0.001). Matched tubular and colloid cancers (n = 112) had similar OS (P = 0.55). On multivariable Cox regression, PanIN-derived PDAC was associated with worse OS than IPMN-derived (HR: 1.66, 95% CI: 1.44-1.90) and tubular IPMN-derived (HR: 1.53, 95% CI: 1.32-1.77) PDAC. Colloid and tubular subtype was not associated with OS (P = 0.16).
CONCLUSIONS
PanIN-derived PDAC has worse survival than IPMN-derived PDAC supporting distinct outcomes. Although more indolent, colloid IPMN-derived PDAC has similar survival to tubular after risk adjustment.
背景与目的
导管内乳头状黏液性肿瘤（IPMN）衍生的胰腺导管腺癌（PDAC）的管理通常是从胰腺上皮内瘤变（PanIN）衍生的PDAC指南外推而来。然而，它们在生物学上存在差异，并且在管状和胶样亚型之间进一步存在异质性。
方法
从国际中心（2000 - 2019年）回顾性识别连续接受 upfront 手术的 PanIN 衍生和 IPMN 衍生的 PDAC 患者。对临床病理因素进行一对一倾向评分匹配，产生三个队列：IPMN 衍生与 PanIN 衍生的 PDAC、管状 IPMN 衍生与 PanIN 衍生的 PDAC、以及管状与胶样 IPMN 衍生的 PDAC。使用 Kaplan - Meier 法和对数秩检验比较总生存期（OS）。多变量 Cox 回归确定相应的风险比（HR）和95%置信区间（95%CI）。
结果
2350例 PanIN 衍生和700例 IPMN 衍生的 PDAC 患者的中位 OS（mOS）分别为23.0个月和43.1个月（P < 0.001）。PanIN 衍生的 PDAC 在 T 分期、CA19 - 9、分级和淋巴结状态方面更差。管状亚型在 T 分期、CA19 - 9、分级、淋巴结状态和 R1 切缘方面更差，胶样亚型的 mOS 为94.1个月，而管状亚型为33.7个月（P < 0.001）。匹配（n = 495）的 PanIN 衍生和 IPMN 衍生 PDAC 的 mOS 分别为30.6个月和42.8个月（P < 0.001）。在匹配（n = 341）的 PanIN 衍生和管状 IPMN 衍生的 PDAC 中，mOS 仍然较差（27.7对37.4，P < 0.001）。匹配的管状和胶样癌（n = 112）具有相似的 OS（P = 0.55）。在多变量 Cox 回归中，PanIN 衍生的 PDAC 与比 IPMN 衍生（HR：1.66，95%CI：l.44 - 1.90）和管状 IPMN 衍生（HR：1.53，95%CI：1.32 - 1.77）的 PDAC 更差的 OS 相关。胶样和管状亚型与 OS 无关（P = 0.16）。
结论
PanIN 衍生的 PDAC 比 IPMN 衍生的 PDAC 生存率更差，支持不同的预后。尽管胶样 IPMN 衍生的 PDAC 更惰性，但在风险调整后与管状亚型具有相似的生存率。
