The Role of Dexmedetomidine in Tumor-Progressive Factors in the Perioperative Period and Cancer Recurrence: A Narrative Review.

ABSTRACT: Dexmedetomidine, a specific α2 adrenergic receptor agonist, is highly frequently used in the perioperatively for its favorable pharmacology, such as mitigating postoperative cognitive dysfunction. Increasing attention has been recently focused on the effect of whether dexmedetomidine influences cancer recurrence, which urges the discussion of the role of dexmedetomidine in tumor-progressive factors. The pharmacologic characteristics of dexmedetomidine, the tumor-progressive factors in the perioperative period, and the relationships between dexmedetomidine and tumor-progressive factors were described in this review. Available evidence suggests that dexmedetomidine could reduce the degree of immune function suppression, such as keeping the number of CD3+ cells, NK cells, CD4+/CD8+ ratio, and Th1/Th2 ratio stable and decreasing the level of proinflammatory cytokine (interleukin 6 and tumor necrosis factor-alpha) during cancer operations. However, dexmedetomidine exhibits different roles in cell biological behavior depending on cancer cell types. The conclusions on whether dexmedetomidine would influence cancer recurrence could not be currently drawn for the lack of strong clinical evidence. Therefore, this is still a new area that needs further exploration.

Project description:BackgroundThis study aimed to explore the clinical characteristics of perioperative acute gout attacks in patients with varying uric acid levels undergoing orthopedic surgery, identify the risk factors for gout recurrence within the first postoperative year, and provide a disease prevention and diagnostic reference.MethodsThis hospital-based retrospective study was conducted between January 2018 and December 2020. According to the blood uric acid levels at admission, the patients were grouped into either the normal uric acid level group or the hyperuricemia group. Patient comorbidities, serum uric acid levels, inflammatory indicators, follow-up recurrence rates, and other indicators were compared.ResultThe uric acid decline ratio and the inflammatory indexes (white blood cell count and C-reactive protein level) at the time of the attack were significantly higher in the normal uric acid level group than in the hyperuricemia group (P < 0.05). Patients in the hyperuricemia group with diabetes and tophi and those administered diuretics were more prone to acute gout attacks than those in the normal uric acid level group (P < 0.05). In the normal uric acid level group, 22 patients (84.6%) exhibited single joint involvement, whereas only 18 patients (47.4%) in the hyperuricemia group demonstrated single joint involvement (P < 0.05). After 1 year of follow-up, the gout recurrence rate in the hyperuricemia group was 44.7%, which was significantly higher that the recurrence rate in the normoglycemic group (11.5%; P < 0.05). Presenting tophi in perioperative orthopedic surgery patients was found to be an independent risk factor for gout recurrence within 1 year (RR = 4.80; P = 0.029).ConclusionThe recurrence rate of gout in patients with hyperuricemia during perioperative period increased 1 year after operation. Therefore, it is crucial to monitor the uric acid level to prevent acute gout attacks during the perioperative period and recurrence during the 1-year follow-up period. Moreover, the risk of an acute gout recurrence 1 year after operation increased in patients who presented tophi; therefore, it is necessary to maintain appropriate blood uric acid level during perioperative period among patients undergoing orthopedic surgery.

Project description:Background and objectiveWith the emergence of immunotherapy and targeted therapies, there are more options for the perioperative period management of muscle-invasive bladder cancer (MIBC), and various types of clinical studies are emerging, leading to the need to explore ways to choose the optimal treatment modality. This review aims to synthesize past and present treatment modalities and to explore future trends in the perioperative period cares of MIBC for the benefit of clinical practitioners.MethodsA non-systematic, literature search was conducted between March 5, 2023 and November 30, 2023 on PubMed using "perioperative period", "MIBC", "chemotherapy", "radiotherapy", "immunotherapy", "targeted treatment" and "combination" as keywords, along with a search for ongoing clinical studies that were related to the perioperative period of MIBC on classic.clinicaltrials.gov, some latest conference abstracts were also included as references.Key content and findingsThe trend towards benefit from adjuvant chemotherapy in perioperative chemotherapy is gradually being recognized. Neoadjuvant immunotherapy, including single-agent immunization, like programmed cell death protein 1 (PD-1) inhibitors, programmed cell death 1 ligand 1 (PD-L1) inhibitors and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitors, and double-immunization, has been confirmed by several clinical studies to be beneficial to clinical remission rates, and the combination regimen is superior to single-agent therapy. Targeted therapies such as antibody-drug conjugate (ADC) are entering MIBC perioperative studies. Multiple sequential and combination clinical studies are gradually disclosing preliminary data on efficacy and safety.ConclusionsImmunotherapy would become an essential perioperative treatment for MIBC, and continuous and integrated perioperative management may become the MIBC treatment mode of the future. ADC medicines will also be a hot research focus in the coming years.
