Efficacy and Safety of Sorafenib Therapy on Metastatic Renal Cell Carcinoma in Korean Patients: Results from a Retrospective Multicenter Study.

ABSTRACT:

Objective

To evaluate the efficacy and safety of sorafenib for Korean patients with metastatic renal cell carcinoma (mRCC).

Methods

A total of 177 mRCC patients using sorafenib as first- (N = 116), second- (N = 43), and third-line (N = 18) therapies were enrolled from 11 Korean centers between 2006 and 2012. The patient characteristics, therapy duration, tumor response, disease control rate, and tolerability were assessed at baseline and at routine follow-ups, and the progression-free survival (PFS) and overall survival (OS) times and rates were analyzed.

Results

Among all patients, 18 (10.2%) stopped sorafenib treatment for a median of 1.7 weeks, including 15 (8.5%) who discontinued the drug, while 40 (22.6%) and 12 (6.8%) patients required dose reductions and drug interruptions, respectively. Severe adverse events (AEs) or poor compliance was observed in 64 (36.2%) patients, with 118 (7.4%) ?grade 3 AEs. During the treatment, one myocardial infarction was observed. The number of ?grade 3 AEs in the first-line sorafenib group was 71 (6.8% of the total 1048 AEs). During a median follow-up of 17.2 months, the radiologically confirmed best objective response rate, disease control rate, median PFS, and median OS were 22.0%, 53.0%, 6.4 months (95% confidence interval [CI], 5.2-8.9), and 32.6 months (95% CI, 27.3-63.8) for the total 177 sorafenib-treated patients, respectively, and 23.2%, 56.0%, 7.4 months (95% CI, 5.5-10.5), and not reached yet (95% CI, 1.0-31.1) for the first-line sorafenib group, respectively.

Conclusions

Sorafenib produced tolerable safety, with a ?grade 3 AE rate of 7.4% and an acceptable disease control rate (53.0%) in Korean mRCC patients.

Project description:BackgroundPazopanib was recommended as first-line treatment option for Metastatic renal cell carcinoma (mRCC), while evidence from strictly selected patients has poor external validity and clinical characteristics are complex in real-world clinical practice. This study aimed to illustrate the survival benefits and safety of pazopanib monotherapy using real-world data of mRCC patients.MethodsThis was a retrospective, multicenter, cohort study. We recruited adult patients with International Metastatic renal cell carcinoma Database Consortium (IMDC) favorable- and intermediate-risk mRCC receiving first-line pazopanib from May 2017 to February 2020. Patients were treated with pazopanib 800 mg or 600 mg orally once daily. Treatment efficacy, and drug safety were analyzed. Response was evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Drug safety was assessed according to the grade of treatment-related adverse reactions.ResultsBased on IMDC risk stratification, there were 46 (32.2%) patients in the favorable-risk group and 97 (67.8%) patients in the intermediate-risk group. The median progression-free survival (PFS) of the entire cohort, favorable- and intermediate risk groups was 21.2, 27.1 and 17.2 months, respectively. In the intermediate-risk group, PFS was much longer in patients with 1 risk factor than in patients with 2 risk factors, with a median of 25.9 months versus 11.2 months (P<0.0001). Patients with lung metastasis only had longer PFS than those with bone metastasis only, with a median PFS of 25.9 vs. 21.2 months, respectively. Furthermore, local therapy for the metastatic site appeared to benefit patients in the IMDC favorable-risk group but not those in the IMDC intermediate-risk group. The best response was 40/140 (29%) partial response (PR), 86/140 (61%) stable disease (SD), and 14/140 (10%) progressive disease (PD). The most common adverse drug reactions (ADRs) were change in hair color (47.7%), hypertension (40.0%), diarrhea (40.0%), proteinuria (38.5%), elevation of transaminase (35.4%), and hand-foot skin reaction (32.3%).ConclusionsThis real-world data analysis recommended that patients in intermediate-risk group need to be further stratified according to the number of risk factors. Pazopanib was most suitable for patients with lung metastasis only. Local treatment for metastatic lesions should only be recommended in IMDC favorable patients.

Project description:Purpose: Sorafenib and sunitinib are extensively used as first-line medications for metastatic renal cell carcinoma (mRCC). This meta-analysis was conducted to assess the antitumor efficacy, toxicity, and costs of the two drugs among mRCC patients. Materials and methods: PubMed, ScienceDirect, Scopus, Web of Science, Ovid MEDLINE, the Cochrane Library, Embase, and Google Scholar were searched for eligible articles. The endpoints consisted of progression-free survival (PFS), overall survival (OS), objective response rate (ORR), adverse effects (AEs), and per-patient-per-month (PPPM) costs. Results: We included 14 studies with 2,925 patients. Both drugs were valid for treating mRCC with equivalent PFS [hazard ratio (HR) = 0.98, 95% confidence interval (CI): 0.88-1.10, P = 0.74] and disease control rates [DCRs; risk ratio (RR) = 1.03, 95% CI: 0.98-1.08, P = 0.28], but sunitinib had a better OS (HR = 1.10, 95% CI: 1.01-1.20, P = 0.04) and higher ORR (HR = 0.66, 95% CI: 0.45-0.97, P = 0.03) than sorafenib. Furthermore, sunitinib induced more incidences of severe hematologic AEs (anemia, neutropenia, and thrombocytopenia) and stomatitis/mucositis than sorafenib. In the subanalysis, Asian patients treated with sorafenib reported a longer PFS than those treated with sunitinib (HR = 0.87, 95% CI: 0.83-0.90, P = 0.01), and European patients treated with sunitinib had a longer OS than those treated with sorafenib (HR = 1.17, 95% CI: 1.01-1.30, P = 0.04). Moreover, the pooled results of the high-quality studies reported a higher ORR with sunitinib than with sorafenib, and medium-quality studies showed a longer OS with sunitinib than with sorafenib. Conclusions: Sunitinib has more benefits (longer OS and better ORR) than sorafenib as a first-line therapy for mRCC. However, sunitinib has higher toxicity than sorafenib. Sorafenib might be more suitable than sunitinib among Asian patients, and sunitinib might be superior to sorafenib in European patients. Nevertheless, more large-scale, high-quality studies are required.
