sitagliptin-phosphate and Neoplasms

Observational studies and meta-analyses of randomized trials on dipeptidyl peptidase-4 inhibitors (DPP4i) reported discordant results on the risk of malignancies with this class of drugs. Aim of the present meta-analysis is the assessment of the effect of DPP4i treatment on the incidence of different types of cancer, collecting all available evidence from randomized controlled trials.. An extensive MEDLINE, EMBASE, and Cochrane database search for sitagliptin or vildagliptin or omarigliptin or saxagliptin or alogliptin or trelagliptin or anagliptin or linagliptin or gemigliptin or evogliptin or teneligliptin was performed up to September 30th, 2019. All trials performed on type 2 diabetes, with duration ≥ 24 weeks, and comparing of DPP4i with placebo or active drugs were collected. The study has been registered on PROSPERO (#153344). Mantel-Haenszel odds ratio (MH-OR) with 95% confidence interval (95% CI) was calculated for all outcomes.. A total of 157 eligible trials were identified. DPP-4i were not associated with an increased risk of overall cancer (MH-OR 0.93 [0.86, 1.00]; p = 0.07), with no significant differences across individual molecules of the class. When compared with placebo/none, a lower risk of cancer with DPP-4i was observed in placebo-controlled trials (MH-OR 0.90 [0.82, 0.99], p = 0.030), whereas no significant differences have been detected with any other comparators. DPP-4i was associated with a significant reduction in colorectal cancer (MH-OR 0.70 [0.53, 0.94], p = 0.020).. Available data do not support the hypothesis of an association of DPP4i treatment with malignancies, with a possible beneficial effect for colon-rectal cancer.

With vildagliptin and sitagliptin on the market for the treatment of type 2 diabetes, dipeptidyl peptidase 4 (DPP4, EC 3.4.14.5) research has entered a new era. Scientists aim to uncover the broader pharmacological profile of DPP4 inhibitors and search for therapeutic opportunities outside diabetes. During the pre-clinical and clinical evaluation of vildagliptin and sitagliptin, there has been a growing awareness of the presence of other DPP4-like peptidases in various cells and tissues. This fuelled the development of more inhibitors with defined selectivity for DPP2, 8 and 9 that were used to investigate the expression, distribution and regulation of these peptidases. In turn, these studies increased the insights in the role of DPP4 in the body's response to various insults.

Diabetes mellitus is a frequent comorbidity of cancer patients. The growing epidemic of diabetes is anticipated to have tremendous impact on health care. Diabetes may negatively impact both cancer risk and outcomes of treatment. Oncology nurses are ideally positioned to identify patients at risk for complications that arise from cancer treatment in the setting of pre-existing diabetes. Additionally, oncology nurses may be the first to identify underlying hyperglycemia/hidden diabetes in a patient undergoing cancer treatment. Strategies for assessment and treatment will be discussed, along with specific strategies for managing hyperglycemia, potential renal toxicity, and peripheral neuropathy. Guidelines for aggressive treatment of hyperglycemia to minimize risks of complications will be reviewed. The role of interdisciplinary care, utilizing current evidence, is crucial to supporting patients and their families as they manage the challenges of facing two life-limiting diseases. Whole-person assessment and individualized treatment plans are key to maximizing quality of life for patients with cancer and diabetes.
