However, given the limitations of CAR-T cell therapy, such as low tumor infiltration and clinical efficacy in solid tumors, there has been significant interest in recent years to engineer other immune cell types, including neutrophils, with CARs because they provide special advantages for cancer therapy, such as rapid infiltration into tumor sites, strong cytotoxic functions, and the ability to modify the tumor microenvironment (TME). However, the main barriers to the practical translation of CAR-neutrophils are their short lifespan, restricted ex vivo proliferation, and inherent resistance to genetic alterations, which calls for the availability of an infinite source for the ongoing supply of CAR-neutrophil therapy. These obstacles may be overcome by developments in induced pluripotent stem cell (iPSC) technology, which offers a consistent, renewable, and genetically changeable source of CAR-neutrophils (CAR-Neuts).

Early detection of cancer is one of the most difficult processes, especially when it comes to the differentiation of cancer's structure, length, and size. AI methodology offers innovations and decision-making applicable to specific processes like data collecting, management, results, and conclusions. Due to the lack of particular indicators, the difficult location of the pancreas, and the absence of early symptoms, pancreatic cancer (PC) is difficult to identify with low and late analysis. However, the imaging approach is slightly improving analysis, but there is still potential for enhancement in systematizing guidelines. This comprehensive review will mainly focus on various applications of AI in pancreatic cancer diagnosis. Furthermore, this review presents various architectures based on machine learning (ML) and deep learning (DL) methods for applications such as early detection, classification, tumor staging, and pancreatic cancer survival prediction. In order to better comprehend challenging cases, clinical practitioners can benefit from the supplementary information and useful recommendations provided by various techniques. Finally, this review potentially analyzes the advantages and drawbacks present in pancreatic cancer.
