  OBJECTIVE: To clarify the molecular mechanism of remnant pancreatic cancer (PC) development after primary PC resection. BACKGROUND: Molecular mechanisms of the development of remnant PCs after primary PC resection are largely unknown. METHODS: Forty-three patients undergoing remnant PC resection after primary PC resection between 2001 and 2017 at 26 institutes were retrospectively analyzed. Clinicopathologic features and molecular alterations detected by targeted amplicon sequencing of 36 PC-associated genes were evaluated. RESULTS: These patients showed significantly lower body mass indices and higher hemoglobin A1c values at remnant PC resection than at primary PC resection. A comparison of the molecular features between primary and remnant PCs indicated that remnant PCs were likely to develop through 3 different molecular pathways: successional, showing identical and accumulated alterations (n = 14); phylogenic, showing identical and distinct alterations (n = 26); and distinct, showing independent distinctive alterations (n = 3). The similarity of gene alterations was associated with time to the remnant PC development ( r = 0.384, P = 0.0173). Phylogenic pathways were significantly associated with the intraductal spread of carcinoma ( P = 0.007). Patient survival did not differ significantly depending on these molecular pathways. CONCLUSIONS: Molecular profiling uncovered 3 pathways for the development of remnant PCs, namely, successional, phylogenic, and distinct pathways. The vast majority of remnant PCs are likely to be molecularly associated with primary PCs either in the successional or phylogenic way. This information could impact the design of a strategy for monitoring and treating remnant PCs.

  　View Summary

  BACKGROUND: The Community-based assessment for Clinical and Emergency Practice (C-CEP) scale is a validated tool comprising 15 items across four components: "Attitude and Communication in Emergency Medicine," "Basic Clinical Skills," "Knowledge about Community Medicine," and "Knowledge in Evidence-Based Medicine." The C-CEP scale enables medical students' self-assessment of their confidence in clinical and emergency care. This study aimed to evaluate whether a two-week comprehensive general practice clerkship would improve C-CEP scores and to identify the specific training elements contributing to increased confidence in primary care, particularly in emergency responses. METHODS: After obtaining ethical approval and written informed consent, fifth-year medical students at Sapporo Medical University who participated in two-week off-campus clerkships at external healthcare facilities (hospitals) during the 2023 academic year were included. Pre- and post-clerkship C-CEP scores were collected. Changes in the baseline and average scores were analyzed across facilities accepting more than four trainees. Text mining was conducted on students' reflective portfolios from the facilities with significant findings to identify frequent and co-occurring words related to confidence-building activities. RESULTS: Out of 115 eligible participants, 97 students were included in the analysis (84.3% participation rate). The data from seven facilities accepting more than four trainees, representing 74 students in total, were analyzed. These facilities averaged 243 beds, were located 147 km from the medical school, and had an emergency admission rate of 84.6%. C-CEP scores showed significant improvement across all components post-clerkship (p < 0.05). Although pre-clerkship scores did not differ significantly across facilities, post-clerkship score increases varied. Multivariate analysis identified Facilities D and F as exhibiting significant differences in confidence improvement compared with the other facilities (R² = 0.20, p = 0.0379). Text mining highlighted that Facility F emphasized active learning activities such as "interviews," "examinations," and "conferences," whereas Facility D focused on passive activities such as "observation", which were associated with limited impact on trainee confidence. CONCLUSION: The C-CEP effectively measured confidence improvements in primary care and emergency responses among fifth-year medical students following their clinical clerkships. The C-CEP scale's ability to detect inter-facility differences highlights its potential to inform and refine clinical education programs, ensuring more targeted and effective training.

  BACKGROUND AND AIM: Endoscopic ultrasound shear wave elastography (EUS-SWE) can facilitate an objective evaluation of pancreatic fibrosis. Although it is primarily applied in evaluating chronic pancreatitis, its efficacy in assessing early chronic pancreatitis (ECP) remains underinvestigated. This study evaluated the diagnostic accuracy of EUS-SWE for assessing ECP diagnosed using the Japanese diagnostic criteria 2019. METHODS: In total, 657 patients underwent EUS-SWE. Propensity score matching was used, and the participants were classified into the ECP and normal groups. ECP was diagnosed using the Japanese diagnostic criteria 2019. Pancreatic stiffness was assessed based on velocity (Vs) on EUS-SWE, and the optimal Vs cutoff value for ECP diagnosis was determined. A practical shear wave Vs value of ≥50% was considered significant. RESULTS: Each group included 22 patients. The ECP group had higher pancreatic stiffness than the normal group (2.31 ± 0.67 m/s vs. 1.59 ± 0.40 m/s, p < 0.001). The Vs cutoff value for the diagnostic accuracy of ECP, as determined using the receiver operating characteristic curve, was 2.24m/s, with an area under the curve of 0.82 (95% confidence interval: 0.69-0.94). A high Vs was strongly correlated with the number of EUS findings (rs = 0.626, p < 0.001). Multiple regression analysis revealed that a history of acute pancreatitis and ≥2 EUS findings were independent predictors of a high Vs. CONCLUSIONS: There is a strong correlation between EUS-SWE findings and the Japanese diagnostic criteria 2019 for ECP. Hence, EUS-SWE can be an objective and invaluable diagnostic tool for ECP diagnosis.

  　View Summary

  In the present study, a significantly strong correlation was found between the imaging parameter (Fis) of perfusion CT, which targeted the contrast accumulation in the intstitial space and relects tumor-associated stroma in this model, and stromal density quantified using immunohistochemistry; this finding supported our hypothesis that perfusion CT had the potential to depict a similar spatial distribution of tumor-associated stroma to that confirmed using histopathological analysis. In terms of the association between tumor hypoxia and tumor-associated stroma, FMISO uptake had a negative correlation with Fis and stromal density, as well as with vascular parameters. These results suggest that tumor hypoxia was complementarily localized to tumor-associated stroma and the vascular component.

  　View Summary

  研初年度は、各参加施設問で共通の重症急性膵炎患者登録データベースを作成した。ついで、各参加施設での倫理委員会の承認を経て多施設共同研究を開始し、UMINに登録、StudyDesignを公開した。研究期間を通して臨床データは採取し続け(膵局所血流障害の診断、血管透過性亢進の評価)は各症例にて、毎回評価しデータベースに登録を継続し、2012年12月78例の登録され、統計学的に十分なサンプル数であったため症例の集積は終了し、現在、解析中である。 また、1年目の目標であったヒト重症急性膵炎患者における局所(膵実質)血流障害の有無と血清Angiopoietin(ANG)2値の上昇が関係の検討を行ったところ、両者の間に有意な差を認めず、むしろ、Perfusion CTによって診断された全身性の血流異常とANG2との間で有意な相関を得た。ANG1、VEGF-A,VEGF-Bは、局所(膵実質)血流異常および全身性の血流異常のどちらとも相関を認めなかった(Watanabe T, Tsuji Y et a1. Am J Gastroenterol. 2011)。また、高ANG2を伴った重症急性膵炎患者における全身循環不全は実際に多臓器不全と有意に関係することを論文発表した(Watanabe T, Tsuji Y et al. Pancreas 2013)。 重症急性膵炎における全身性血流異常は多臓器不全の原因となり、これを改善するために一日6-10Lもの輸液を要すると治療ガイドラインにも指摘されている。こうした大量輸液はともすると輸液過剰になり、生命予後の悪化の一因にもなりうる。適切な輸液量を決めるために、全身性の血流異常を簡便に評価する必要があるが、有用なマーカーが存在せず積年の問題であった。一方、我々の結果では、Ang-2が全身性の血流異常の評価の指標となりうる可能性が示唆された。
