Treatment efficacy and safety of regorafenib plus drug-eluting beads-transarterial chemoembolization versus regorafenib monotherapy in colorectal cancer liver metastasis patients who fail standard treatment regimens.

ABSTRACT:

Objective

This study aimed to evaluate the efficacy and safety of regorafenib plus drug-eluting beads-transarterial chemoembolization (DEB-TACE) versus regorafenib monotherapy in colorectal cancer liver metastases (CRLM) patients who failed standard treatment regimens.

Methods

Totally, 76 eligible CRLM patients were analyzed, among which 42 patients received regorafenib monotherapy (as regorafenib group) and 34 patients received regorafenib plus DEB-TACE (as regorafenib plus DEB-TACE group).

Results

Objective response rate (35.3% versus 7.1%, P = 0.002) and disease control rate (76.5% versus 47.6%, P = 0.011) were both increased in regorafenib plus DEB-TACE group compared with regorafenib group; meanwhile, negative conversion rate of carcinoembryonic antigen (66.7% versus 28.6%, P = 0.008) after treatment was elevated in regorafenib plus DEB-TACE group compared with regorafenib group. Notably, progression-free survival (PFS) (median value: 7.6 versus 4.1 months, P < 0.001) and overall survival (OS) (median value: 15.7 versus 9.2 months, P < 0.001) were both higher in regorafenib plus DEB-TACE group compared with regorafenib group. Furthermore, liver function indexes (alanine transaminase, aspartate aminotransferase, and cholinesterase levels) after treatment were all similar between the two groups (all P > 0.05). In addition, the occurrences of upper abdominal distending pain (P < 0.001), nausea and vomiting (P = 0.002) and fever (P = 0.002) were higher in regorafenib plus DEB-TACE group compared with regorafenib group, while the majority of these adverse events were mild and tolerable.

Conclusions

Regorafenib plus DEB-TACE is superior to regorafenib monotherapy regarding treatment response, PFS and OS, while induces tolerable post-embolization syndrome in CRLM patients who fail standard treatment regimens.

Project description:BackgroundPatients with small cell lung cancer (SCLC) are prone to developing refractoriness to standard treatment, and some patients are ineligible for systemic therapy owing to comorbidities or poor pulmonary function. The prognosis of patient with standard treatment-refractory/ineligible (STRI)-SCLC remains poor. This retrospective cohort study aimed to investigate the efficacy and safety of drug-eluting beads bronchial arterial chemoembolization (DEB-BACE) for the treatment of SRTI-SCLC and to identify the predictors of overall survival (OS).MethodsA total of 18 patients with STRI-SCLC who received DEB-BACE were included. Treatment response, adverse events, progression-free survival (PFS), and OS were evaluated. Further molecular targeted therapy or immunotherapy was administered as a second-line treatment or beyond for those patients who had not received these regimens previously. Univariate and multivariate Cox analyses were used to explore the predictors of OS for STRI-SCLC treated with DEB-BACE.ResultsThe overall disease control rate at 3 months after DEB-BACE was 77.8% (14/18); of these patients who experienced disease control, partial response and stable disease were achieved in 2 patients (11.1%) and 12 patients (66.7%), respectively. There were 7 patients (38.9%) who received anlotinib after DEB-BACE. No severe DEB-BACE-related or anlotinib-related adverse events were observed. The median PFS was 5.0 months; the 6- and 12-month PFS rates were 55.6% (10/18) and 11.1% (2/18), respectively. The median OS was 9.0 months; the 6- and 12-month OS rates were 77.8% (14/18) and 33.3% (6/18), respectively. Postoperative anlotinib [hazard ratio: 0.302; 95% confidence interval (CI): 0.098-0.930; P=0.037] was identified as the predictor of OS in patients with STRI-SCLC treated with DEB-BACE.ConclusionsDEB-BACE is an effective and well-tolerated approach for patients with STRI-SCLC. Postoperative anlotinib is the predictor of OS and may indicate a better prognosis for patients with STRI-SCLC.
