Immunoglobulin G4 (IgG4)-related autoimmune pancreatitis (AIP), also known as “type 1 AIP,” is a rare, chronic, and fibroinflammatory disease manifested as obstructive jaundice and enlargement of the pancreas, usually accompanied by extra-pancreatic organ involvement. The understanding of IgG4-related AIP is gradually deepening. In this review, we summarized the basic concepts, common clinical manifestations, and new progress of the disease including diagnostic, therapeutic strategies, and prognosis mainly based on published case reports, cohort studies, meta-analyses, and guidelines in the past 5 years. Issues such as diagnostic markers, risk factors for relapse, and more effective treatment still need to be further studied.

Pancreatic ductal adenocarcinoma (PDAC) is the most common type and composes about 90% of pancreatic cancer featured with high intra-tumoral heterogeneity and poor prognosis, which has been considered the least immunogenic cancer for decades. However, this characterization might be over-simplistic, and more sophisticated approaches are needed to develop effective treatment strategies. In this review, we aim to summarize studies involving PDAC immunity in different aspects to provide a multidimensional recognition and comprehensively understanding of the mechanisms underlying the tumor microenvironment (TME) of PDAC. A database search of peer-reviewed articles published in English between 2003 and 2022 in PubMed and the Web of Science was performed. Original articles and review articles relevant to the topic were selected. We emphasized the importance of investigating tumor-infiltrating lymphocytes (TILs) in pancreatic cancer, especially focusing on CD8+ T cells, along with indicating potential therapeutic strategies to turn the immune-cold PDACs into the immune-hot ones.
胰腺导管腺癌（PDAC）是最常见的类型，约占癌症的90%，肿瘤内异质性高，预后差，几十年来一直被认为是免疫原性最低的癌症。然而，这种表征可能过于简单，需要更复杂的方法来制定有效的治疗策略。在这篇综述中，我们旨在总结不同方面涉及PDAC免疫的研究，以提供对PDAC肿瘤微环境（TME）潜在机制的多维认识和全面理解。对2003年至2022年间发表在PubMed和Web of Science上的英文同行评审文章进行了数据库搜索。选择了与该主题相关的原创文章和评论文章。我们强调了研究胰腺癌症中肿瘤浸润性淋巴细胞（TIL）的重要性，特别是关注CD8+T细胞，并指出了将免疫冷PDAC转化为免疫热PDAC的潜在治疗策略。

Pancreatic ductal adenocarcinoma (PDAC) originates in the exocrine pancreas and accounts for 95% of pancreatic cancers, with 5-year survival rates of approximately 10%. Multiple factors are involved in PDAC pathogenesis, including internal genetic alterations and external inflammation-related stimuli. Overflow of exocrine pancreatic enzymes caused by PDAC obstruction inevitably results in autolysis of surrounding normal cells and extracellular matrix, generating tissue damage-related inflammation; however, this process does not cause autolysis of PDAC cells. How tumor cells acquire resistance to pancreatic enzymatic digestion has been ignored for a long time. In this review, we discuss how PDAC cells mobilize gasdermin E, a pore-forming protein, to achieve resistance to autolysis by pancreatic digestive enzymes.

ancreatic necrosis occurs in approximately 15% to 20% of patients with acute pancreatitis (AP); 1/3 of patients are diagnosed with infected pancreatic necrosis (IPN), which has a mortality rate of 30%. It is the chief reason for the second “death peak” of AP patients in the later stage of the disease. [1] As one of the most vital treatment methods for IPN, pancreatic necrosectomy has developed rapidly in the past 30 years, including improvements and breakthroughs in surgical timing, approach, and strategies, and a significant reduction in postoperative mortality from the initial 30% to 40%. In particular, with the innovation of laparoscopic and endoscopic tech- niques, pancreatic surgeons have more choices in the face of IPN. Currently, how to optimize treatment and maximize the benefits for IPN patients has become a topic of great concern and controversy in the treatment of IPN.

The significance of exosomes has emerged in a variety of physiological processes and diseases. Pancreatic cancer remains one of the most lethal diseases at present. Recently, increasing evidence has suggested that exosomes are vital for mediating the elaborate interaction of highly heterogeneous cell clusters within the pancreatic tumor microenvironment, contributing to activating pancreatic stellate cells and cancer-associated fibroblasts, compromising immune cells, and enhancing angiogenesis. Besides their natural and intrinsic roles, exosomes may provide a novel potential way for pancreatic cancer management and therapy as well. Thus, exosomes not only mediate cellular communication during pancreatic cancer progression but also serve as a promising player in precise pancreatic cancer management and treatment. To comprehensively summarize the role of exosomes in pancreatic cancer, we searched the PubMed database and reviewed all relevant original studies.

Progress in medicine requires not only innovation and development in the medical field but also the integration of the technology of other fields into the medical field. As an important technological advancement, three-dimensional (3D) reconstruction transforms traditional two-dimensional images into 3D images that are more consistent with the physiological habits of human eyes. It has been applied to the bones, heart, liver, and maxillofacial area, promoting the progress of medical technology and surgeons. This article introduces the progress of 3D reconstruction technology in the clinical application of pancreatic surgery, from the preoperative, intraoperative, and postoperative perspectives, as well as the education of young surgeons. It also puts forward new ideas for the further development of pancreatic surgery.

Acute pancreatitis (AP) is a complicated disease with rising incidence over the years. Twenty percent of AP will develop into acute necrotizing pancreatitis (ANP). Interventions for ANP have evolved from traditional open surgery to minimally invasive step-up approaches. Infected pancreatic necrosis (IPN) is the most serious event of ANP and associated with extremely poor prognosis. The contrast-enhanced computed tomography(CECT)-based classification of IPN describes various types of IPN and will help to carry out surgical interventions for each subtype. Nevertheless, many challenges are still remaining during the treatment of ANP. Including the balance between endoscopic and surgical approaches, and the selection of optimal timing of surgical intervention for infected necrosis. In nowadays treatment scenario of ANP, the necessity for open surgery remains to be debated. Despite of the development of advanced interventional techniques, postoperative residual infection (PRI) remains thorny, and effective prevention and treatment of PRI is of significance.

Objective: Different SSTR2 antagonists have been developed. This study aims to evaluate the impact of different peptides and chelators on the diagnostic performance of SSTR2 antagonists in well-differentiated NETs. Methods: In this prospective study, participants were equally randomized into 2 arms: arm A, participants would undergo a whole-body 68Ga-NODAGA-LM3 PET/CT scan on the first day and 68Ga-DOTA-LM3 PET/CT scan on the second day; arm B, participants would undergo a whole-body 68Ga-NODAGA-LM3 PET/CT scan on the first day and 68Ga-NODAGA-JR11 PET/CT scan on the second day. Biodistribution in normal organs, lesion detection ability, and tumor uptakes were compared within each arm. Results: A total of 40 participants (age, 49.5 ± 13.4, 21 men), 20 in each arm, were recruited in the study. In arm A, 68Ga-DOTA-LM3 showed lower background. However, the lesion detection ability (overall lesion detected, 445 vs 548; P = .005) and the lesion uptake (overall lesions SUVmax, 19.8 ± 17.2 vs 35.3 ± 28.8; P < .001) was significantly lower than those of 68Ga-NODAGA-LM3. In arm B, both 68Ga-NODAGA-LM3 and 68Ga-NODAGA-JR11 showed similar biodistribution and lesion uptake (SUVmax, 28.5 ± 23.8 vs 25.0 ± 20.0; P < .001) despite minor differences. The lesion detection ability was the same between these 2 tracers (overall lesion detected, 503 vs 503). Conclusions: The diagnostic performance of SSTR2 antagonists was sensitive to chelators. Both 68Ga-NODAGA-LM3 and 68Ga-NODAGA-JR11 outperformed 68Ga-DOTA-LM3 with higher lesion uptake and detection ability, of which 68Ga-NODAGA-LM3 had marginally but significantly higher lesion uptake.
