Abstract
Inflammation plays a critical role in several diseases such as cancer, gastric, heart and nervous system diseases. Data suggest that the activation of mammalian target of rapamycin (mTOR) pathway in epithelial cells leads to inflammation. Statins, the inhibitors of the 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA), seem to be able to inhibit the mTOR. Statins are considered to have favorable effects on inflammatory diseases by reducing the complications caused by inflammation and by regulating the inflammatory process and cytokines secretion. This critical review collected data on this topic from clinical, in vivo and in vitro studies published between 1998 and June 2022 in English from databases including PubMed, Google Scholar, Scopus, and Cochrane libraries.

Renal toxicity of targeted therapies for renal cell carcinoma in patients with normal and impaired kidney function. Cancer Chemother Pharmacol 2021; 87:723-742. [PMID: 33768301 PMCID: PMC8110505 DOI: 10.1007/s00280-021-04260-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2020] [Accepted: 03/13/2021] [Indexed: 12/11/2022]
Abstract
The introduction of novel targeted therapies during the last 2 decades has led to a significant improvement in patients' clinical outcomes with renal cell carcinoma. However, this improvement came at the price of a whole new spectrum of adverse events, including renal toxicity. Systemic treatment of patients with kidney neoplasms who often present with impairment of kidney function, even prior to treatment, poses an increasing diagnostic and therapeutic challenge for clinicians. Common lifestyle-related comorbidities, i.e., hypertension and diabetes, may contribute to further impairment of kidney function. The lack of official guidelines and the exclusion of patients with reduced kidney function from the clinical trials of recently approved drugs complicate the issue even further. Early detection and correct management of renal toxic effects are crucial to preserve kidney function and ensure the optimal administration of life-prolonging therapies. This review presents detailed information on the renal toxicities of three groups of drugs commonly used in renal cell carcinoma treatment: tyrosine kinase inhibitors, mammalian target of rapamycin inhibitors, and immune checkpoint inhibitors. We outline the incidence and underlying mechanisms of renal adverse effects with a focus on patients on renal replacement therapy, as well as present suggestions for their management.

Real-world use of temsirolimus in Japanese patients with unresectable or metastatic renal cell carcinoma: recent consideration based on the results of a post-marketing, all-case surveillance study. Jpn J Clin Oncol 2020; 50:940-947. [PMID: 32458996 PMCID: PMC7401718 DOI: 10.1093/jjco/hyaa062] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Accepted: 04/17/2020] [Indexed: 02/06/2023] Open
Abstract
OBJECTIVE A prospective, observational, post-marketing surveillance was conducted to assess the safety and effectiveness of temsirolimus in patients with renal cell carcinoma in Japan. METHODS Patients prescribed temsirolimus for advanced renal cell carcinoma were registered and received temsirolimus (25 mg weekly, intravenous infusion for 30-60 minutes) in routine clinical settings (observation period: 96 weeks). RESULTS Among 1001 patients included in the safety analysis data set (median age, 65.0 years; men, 74.8%; Eastern Cooperative Oncology Group performance status 0 or 1, 69.6%), 778 (77.7%) reported adverse drug reactions. The most common (≥10%) all-grade adverse drug reactions were stomatitis (26.7%), interstitial lung disease (17.3%) and platelet count decreased (11.1%). The incidence rate of grade ≥3 interstitial lung disease was 4.5%. The onset of interstitial lung disease was more frequent after 4-8 weeks of treatment or in patients with lower Eastern Cooperative Oncology Group performance status (21.6% for score 0 vs 8.3% for score 4, P < 0.001). Among 654 patients in the effectiveness analysis data set, the response and clinical benefit rates were 6.7% (95% confidence interval 4.9-8.9) and 53.2% (95% confidence interval 49.3-57.1), respectively. The median progression-free survival was 18.3 weeks (95% confidence interval 16.9-21.1). CONCLUSIONS The safety and effectiveness profile of temsirolimus observed in this study was similar to that observed in the multinational phase 3 study. The results are generalizable to the real-world scenario at the time of this research, and safety and effectiveness of temsirolimus as a subsequent anticancer therapy for renal cell carcinoma warrants further investigation. (ClinicalTrials.gov identifier NCT01210482, NCT01420601).

Abstract
BACKGROUND Patients with severe renal impairment or undergoing hemodialysis are usually excluded from clinical trials. Available data regarding safety and activity of systemic therapies (ST) in hemodialyzed patients are scarce. METHODS Clinical data were searched through PubMed database until April 2020 according to PRISMA criteria. Efficacy, safety and pharmacokinetic (PK) assessment of ST were reported. RESULTS Among 270 references, 56 reports were evaluated in full text: 41 were included for efficacy and 42 for safety analysis (sunitinib n = 68, bevacizumab n = 6, everolimus n = 28, temsirolimus n = 17, sorafenib n = 55, axitinib n = 13, pazopanib n = 13, nivolumab n = 18, cabozantinib n = 0, lenvatinib n = 0, and ipilimumab n = 0). Twelve of the reports included PK assessment among dialyzed patients. Hemodialysis did not seem to modify the expected efficacy and safety of each compound among patients undergoing hemodialysis. PK assessments were not modified in comparison with a population not undergoing dialysis. CONCLUSION Targeted and Immune therapies seem to be effective and can be used among patients undergoing hemodialysis. Due to frailty and comorbidities associated to chronic hemodialysis enhanced vigilance for these therapies within this specific population is recommended. Dedicated prospective clinical trials would definitely help to obtain data with a higher level of evidence.

Abstract
Background The objective of this study was to investigate the prognostic significance of the baseline renal function in metastatic renal cell carcinoma (mRCC) patients treated with molecular-targeted agents. Patients and Methods This study included 408 consecutive mRCC patients receiving molecular-targeted therapy, consisting of 124 patients in group A and 284 patients in group B who had baseline estimated glomerular filtration rates ≥ 60 ml/min/1.73 m2 and < 60 ml/min/1.73 m2, respectively. Results Compared with group A, group B was significantly less likely to have poor prognostic factors, such as a high proportion of patients without nephrectomy. The median overall survivals (OSs) after the initiation of targeted therapy in groups A and B were 21.4 and 35.8 months, respectively, and there was a significant difference in the OS between the 2 groups. However, multivariate analysis showed a lack of independent impact of the baseline renal function on the OS. Furthermore, when patients without a nephrectomy were excluded, no significant difference was noted in the OS between the 2 groups. Conclusion These findings suggested that there was no adverse impact of an unfavorable baseline renal function on the efficacy of targeted agents against mRCC. Thus, molecular-targeted therapy should not be avoided in mRCC patients with an impaired baseline renal function.

Abstract
AIMS Sine efficiency of tyrosine kinase inhibitor (TKI) therapy in dialyzed patients is still unclear we aim to analyze the outcome of treatment in such cohort. PATIENTS & METHODS We analyzed treatment outcomes of patients with clear cell renal cell carcinoma (ccRCC) with special focus on those who were also treated with hemodialysis and described treatment safety and progression-free survival of eight patients treated with TKIs and hemodialysis. DISCUSSION & CONCLUSION Our report supports statement that TKI treatment of dialyzed patients is safe and effective. ccRCC increases risk of developing renal insufficiency as well as end-stage renal disease that require dialysis. Introduction of multitargeted receptor kinase inhibitors (TKIs), including sunitinib, sorafenib and pazopanib significantly expanded life time expectancy of metastatic renal clear cell carcinoma. The advance also applies to patients with ccRCC and end-stage renal disease who undergo dialyses.

Abstract
We retrospectively identified patients with end-stage renal disease undergoing hemodialysis treated with the mammalian target of rapamycin inhibitors as a second- and/or third-line targeted therapy after treatment failure with the tyrosine kinase inhibitors for metastatic renal cell carcinoma. Patient medical records were reviewed to evaluate the response to therapies and treatment-related toxicities. Four patients were identified. All patients had undergone nephrectomy, and one had received immunotherapy before targeted therapy. Two patients had clear cell histology, and the other two had papillary histology. All patients were classified into the intermediate risk group according to the Memorial Sloan-Kettering Cancer Center risk model. All patients were treated with everolimus as a second- or third-line therapy, and two patients were treated with temsirolimus as a second- or third-line therapy after treatment failure with sorafenib or sunitinib. The median duration of everolimus therapy was 6.7 months, whereas that of temsirolimus was 9.5 months. All patients had stable disease as the best response during each period of therapy. There were no severe adverse events. The use of mammalian target of rapamycin inhibitors in patients who previously failed to respond to tyrosine kinase inhibitors appears to be feasible in patients with end-stage renal disease requiring hemodialysis.

Abstract
BACKGROUND To evaluate experience of the use of temsirolimus for metastatic renal cell carcinoma (mRCC) in a single center in Japan. METHODS This study included 55 consecutive patients with mRCC who received temsirolimus in a routine clinical setting, and retrospectively reviewed the comprehensive outcomes of these patients. RESULTS Of the 55 patients, 20 had a Karnofsky performance status of ≤80, and 5, 41 and 9 were classified into favorable, intermediate and poor risk groups, respectively, according to the Memorial Sloan-Kettering Cancer Center model. Initially, 25 mg of temsirolimus was applied weekly; however, dose modification was required in 19 patients, resulting in a relative dose intensity of 90.5 % throughout this series. As the best responses to temsirolimus, 4, 44 and 7 were judged to have a partial response, stable disease and progressive disease, respectively. The median progression-free survival (PFS) and overall survival (OS) of these patients following the introduction of temsirolimus was 7.0 and 25.0 months, respectively. Of several factors examined, only the pretreatment C-reactive protein level was shown to be independently associated with both PFS and OS. The common adverse events related to temsirolimus corresponding to ≥grade 3 were anemia in 4, thrombocytopenia in 3, stomatitis in 3 and hyperglycemia in 3. Quality of life analysis using 36-Item Short Form showed that there were no significant differences in any scale scores between surveys performed before and 3 months after the introduction of temsirolimus. CONCLUSIONS Temsirolimus was well tolerated and facilitated comparatively favorable cancer control in Japanese patients with mRCC.

Abstract
Renal cell carcinoma (RCC) is the most lethal type of genitourinary cancer due to its occult onset and resistance to chemotherapy and radiation. Recently, accumulating evidence has suggested stains, inhibitors of 3-hydroxy-3-methyl glutaryl coenzyme A (HMG-CoA) reductase, were associated with the risk reduction of cancer. In the present study, we aimed to investigate the potential effects of simvastatin on RCC cells and the underlying mechanisms by which simvastatin exerted its actions. With cell viability, colony formation, and flow cytometric apoptosis assays, we found that simvastatin potently suppressed cell growth of A498 and 786-O cells in a time- and dose- dependent manner. Consistently, the xenograft model performed in nude mice exhibited reduced tumor growth with simvastatin treatment. In addition, the inhibitory effects of simvastatin on migration and invasion were also observed in vitro. Mechanically, we presented that simvastatin could suppress the proliferation and motility of RCC cells via inhibiting the phosphorylation of AKT, mTOR, and ERK in a time- and dose- dependent manner. Further investigation of the underlying mechanism revealed simvastatin could exert the anti-tumor effects by suppressing IL-6-induced phosphorylation of JAK2 and STAT3. In conclusion, these findings suggested that simvastatin-induced apoptosis and its anti-metastasis activity in RCC cells were accompanied by inhibition of AKT/mTOR, ERK, and JAK2/STAT3 pathways, which imply that simvastatin may be a potential therapeutic agent for the treatment of RCC patients.
