Pancreatic ductal adenocarcinoma (PDAC) ranks among the 15 most prevalent cancers globally, characterized by aggressive growth and late-stage diagnosis. Advances in imaging and surgical techniques have redefined the classification of pancreatic PDAC into resectable, borderline resectable, and locally advanced pancreatic cancer. While surgery remains the most effective treatment, only 20% of patients are eligible at diagnosis, necessitating innovative strategies to improve outcomes. Therefore, traditional treatment paradigms, primarily surgical resection for eligible patients, are increasingly supplemented by neoadjuvant therapies (NAT), which include chemotherapy, radiotherapy, or a combination of both. By administering systemic therapy prior to surgery, NAT aims to reduce tumor size and increase the feasibility of complete surgical resection, thus enhancing overall survival rates and potentially allowing more patients to undergo curative surgeries. Recent advances in treatment protocols, such as FOLFIRINOX and gemcitabine-nab-paclitaxel, now integral to NAT strategies, have shown promising results in increasing the proportion of patients eligible for surgery by effectively reducing tumor size and addressing micrometastatic disease. Additionally, they offer improved response rates and survival benefits compared to traditional regimes. Despite these advancements, the role of NAT continues to evolve, necessitating ongoing research to optimize treatment regimens, minimize adverse effects, and identify patient populations that would benefit most from these approaches. Through a detailed analysis of current literature and recent clinical trials, this review highlights the transformative potential of NAT in managing PDAC, especially in patients with borderline resectable or locally advanced stages, promising a shift towards more personalized and effective management strategies for PDAC.

Current desensitization and maintenance immunosuppression regimens for kidney transplantation in sensitized individuals show limited ability to control the posttransplant humoral response, resulting in high rates of antibody-mediated rejection (ABMR) and graft failure. Here, we showed that anti-CD154 monoclonal antibody (mAb)–based immunosuppression more effectively controlled allograft rejection and humoral rebound in a highly sensitized nonhuman primate kidney transplantation model compared with tacrolimus-based standard-of-care (SOC) immunosuppression. Desensitization with an anti-CD154 mAb (5C8) and a proteasome inhibitor led to decreased donor-specific antibodies (DSAs) and disruption of lymph node germinal centers with reduction of proliferating, memory, and class-switched B cells as well as T follicular helper cells. After transplant, the nonhuman primates maintained on 5C8-based immunosuppression had significantly better survival compared with those maintained on SOC immunosuppression (135.2 days versus 32.8 days, P = 0.013). The 5C8-treated group demonstrated better suppression of DSAs after transplant, more robust suppression of B cell populations, and better induction of regulatory T cells. Fewer infectious and welfare complications, including viral reactivation and weight loss, were also observed with 5C8-based immunosuppression compared with SOC immunosuppression. Therefore, anti-CD154 mAbs may improve kidney transplant outcomes through better control of posttransplant immune responses. The superior efficacy of anti-CD154 mAb–based immunosuppression over tacrolimus-based SOC seen in this highly sensitized NHP transplant model suggests that anti-CD154 mAbs could potentially be used to desensitize and treat highly sensitized patients receiving kidney transplantation.

(1) Background: This study comprehensively compared robotic pancreatic surgery with vascular resection (RPS-VR) to other surgical procedures in the treatment of pancreatic ductal adenocarcinoma (PDAC). (2) Methods: A systematic review of relevant literature was conducted to assess a range of crucial surgical and oncological outcomes. (3) Results: Findings indicate that robotic surgery with vascular resections (VRs) significantly prolongs the duration of surgery compared to other surgical procedures, and they notably demonstrate an equal hospital stay. While some studies reported a lower conversion rate and a higher rate of blood loss and blood transfusion in the RPS-VR group, others found no significant disparity. Furthermore, RPS-VR consistently correlated with comparable recurrence rates, free margins R0, postoperative mortality, and complication rates. Concerning the last one, certain reviews reported a higher rate of major complications. Overall survival and disease-free survival remained comparable between the RPS-VR and other surgical techniques in treating PDAC. (4) Conclusions: The analysis emphasizes how RPS-VR is a resembling approach in terms of surgical outcomes and aligns with existing literature findings in this field.
