Concurrent β-blocker Use is Associated With Improved Outcome in Esophageal Cancer Patients Who Undergo Chemoradiation: A Retrospective Matched-pair Analysis.

ABSTRACT:

Background

β-blocker use has been associated with improved outcomes in a number of different malignancies; however, the impact of β-blockade in esophageal cancer is not been well characterized. We compared the outcomes of esophageal cancer patients based on β-blocker usage.

Methods

The charts of all 418 patients treated with radiation for esophageal cancer at our institution from April 2010 to October 2018 were analyzed. Patients who underwent treatment with palliative intent or did not finish treatment were excluded. β-blocker use was determined from the medication list at time of pretreatment consultation.

Results

There were 291 esophageal cancer patients who received neoadjuvant/definitive chemoradiation therapy. The median follow-up for the cohort was 22.5 months (interquartile range: 9.6 to 41.0 mo). Within the cohort, 27.8% (n=81) of patients were taking β-blockers at the time of treatment. Those taking β-blockers had significantly improved distant control (22.2% vs. 37.9%; P=0.035). Concomitant β-blocker use was significantly associated with improved progression-free survival (P<0.001, hazard ratio=0.42 [0.27-0.66]) and overall survival (P=0.002, hazard ratio=0.55 [0.38-0.81]) on Cox regression analysis. Propensity score-matched pairs were created using tumor stage, nodal stage, sex, neoadjuvant versus definitive therapy, Karnofsky Performance Status, and aspirin use. This matched-pair analysis showed a significant progression-free survival (P=0.005) benefit in esophageal cancer patients taking β-blockers.

Conclusions

Concurrent β-blocker use is common within patients receiving concurrent chemoradiation for esophageal cancer. Esophageal cancer patients who received chemoradiation while taking β-blockers demonstrated significant benefits in survival-based outcomes.

Project description:Purpose: The reported data of elderly ESCC are rather limited and there is a lack of information to guide treatment decisions for elderly patients with esophageal cancer. This study aims to identify the efficacy and factors for optimal treatment approaches for elderly esophageal squamous cell carcinoma (ESCC) treated with radiotherapy (RT) alone or concurrent chemoradiation (CCRT). Methods: This study included 184 I-III elderly ESCC patients aged ≥70 years treated by oral single agent CCRT (sCCRT) or double agents CCRT (dCCRT) or RT alone at a single institution in China. RT was delivered with Intensity Modulated Irradiation Therapy (IMRT) or Volumetric-Modulated Arc Therapy (VMAT). Sequential or simultaneous integrated boost (SIB) approach was applied for GTV dose escalation. Toxicities were evaluated by criteria of Radiation Therapy Oncology Group. Statistical analyses were performed on survival and failure patterns. Results: At a median follow-up time of 15.5 months, the 2- and 3-year estimated overall survival (OS) were 43.5% and 35.2%, respectively. T and N stage, GTV dose (cutoff value 56Gy), simultaneous integrated boost (SIB) technique and CCRT were significant predictors for the outcomes. sCCRT was significantly associated with higher OS, LRFS, and DFS when compared with RT alone and no difference was observed between sCCRT and dCCRT. 44% patients experienced treatment failure, among whom 65.4% developed local failure. 81.3% local failure occurred in GTV and 70.6% regional failures occurred out of radiation field. dCCRT was the only independent prediction factor for grade ≥ 2 neutropenia and gastrointestinal reactions compared with sCCRT and RT alone. No significant difference of toxicities was observed between sCCRT and RT alone. Conclusions: Our results demonstrated that CCRT in elderly patients had significant survival benefit compared to RT alone, especially using Single oral agent. sCCRT had less toxicities compared to dCCRT, and the toxicity was similar to RT alone. GTV dose ≥ 56 Gy and SIB technique were optimal approaches for radiotherapy.

Project description:Concurrent chemoradiation therapy (CCRT) followed by hepatic arterial infusional chemotherapy (HAIC) was reported to be effective for advanced hepatocellular carcinoma (HCC) with portal vein thrombosis. However, transarterial chemoembolization (TACE) is not preferred in this setting. The aim of this study was to assess the factors affecting survival after CCRT, including additional TACE during repeated HAIC.Thirty-eight patients who underwent CCRT as the initial treatment for Barcelona Clinic Liver Cancer stage C HCC with vascular invasion between 2009 and 2016 were reviewed retrospectively. During CCRT, 5-fluorouracil (5-FU) was infused via chemoport during the first and last five days of five weeks of external beam radiation therapy. After CCRT, repeated HAIC with cisplatin and 5-FU was performed monthly. Nineteen patients (50%) underwent additional TACE between repeated HAICs. Factors related to overall survival and progression free survival (PFS) were analyzed.The mean age of patients was 55 years (male:female, 33:5). Underlying liver diseases were hepatitis B, hepatitis C and non-B/C in 29, 1 and 8 patients, respectively. The median radiation dose was 4500 cGy. The objective response (OR) rate at one months after CCRT was 36.8%. The median PFS was 7.4 (range, 1.8 - 32.1) months. The median overall survival was 11.6 (range 2.8-65.7) months. Achieving an OR after CCRT (hazard ratio [HR], 0.028; P < 0.001), additional TACE (HR, 0.134, P < 0.001), and further rounds of HAIC (HR, 0.742, P = 0.001) were independent significant factors related to overall survival. The overall survival duration of patients with an OR after CCRT (median 44.2 vs. 6.6 months, P < 0.001) and additional TACE (median 19.8 vs. 9.1 months, P = 0.001) were significantly greater than those without an OR after CCRT or additional TACE.Patients who achieved an OR after CCRT, underwent additional TACE, and were subjected to repeated rounds of HAIC following CCRT showed better survival after CCRT for advanced stage of HCC with vascular invasion. A further prospective study is needed to confirm the positive effect of additional TACE after CCRT.
