Are patients with stage III non-small cell lung cancer treated with chemoradiotherapy at risk for cardiac events? Results from a retrospective cohort study.

ABSTRACT: OBJECTIVES:Dyspnoea is one of the symptoms frequently encountered after treatment with chemoradiotherapy (CRT) in stage III non-small cell lung cancer (NSCLC). Long-term data on mild to moderately severe cardiac events as underlying cause of dyspnoea in patients with stage III NSCLC are lacking. Therefore, the incidence of new cardiac events, with a common terminology criteria for adverse events (CTCAE) score of ?2 within 5?years after diagnosis, were analysed. DESIGN:Retrospective multicentre cohort study of patients with stage III NSCLC treated with CRT from 2006 to 2013. The medical files of the treated patients were reviewed. OUTCOME MEASURES:The primary endpoint of the study was the incidence of new cardiac events with a CTCAE score of ?2 within 5 years after diagnosis. Secondary endpoint was to identify risk factors associated with the development of a cardiac event. RESULTS:Four hundred and sixty patients were included in the study. Of all patients, 150 (32.6%) developed a new cardiac event. In patients with a known cardiac history (n=138), 44.2% developed an event. The most common cardiac events were arrhythmia (14.6%), heart failure (7.6%) and symptomatic coronary artery disease (6.8%). Pre-existent cardiac comorbidity (HR 1.96; p<0.01) and WHO-performance score ?2 (HR 2.71; p<0.01) were significantly associated with developing a cardiac event. The majority of patients did not have pre-existent cardiac comorbidity (n=322). Elevated WHO/International Society of Hypertension score was not identified as a significant predictor for cardiac events. CONCLUSION:One-third of patients with stage III NSCLC treated in daily clinical practice develop a new cardiac event within 5 years after CRT. All physicians confronted with patients with NSCLC should take cardiac comorbidity as a serious possible explanation for dyspnoea after treatment with CRT.

Project description:BackgroundThe treatment of stage III non-small cell lung cancer (NSCLC) is very challenging because it is a heterogeneous group of diseases. This study was to investigative whether concurrent immunotherapy with chemoradiotherapy was associated with improved outcomes compared to consolidative immunotherapy following chemoradiotherapy in patients with unresectable stage III NSCLC, which may provide evidence-based medical evidence for the treatment of stage III NSCLC.MethodsA total of 78 epidermal growth factor receptor or anaplastic lymphoma kinase (EGFR/ALK) negative patients from the clinical database of the shanghai pulmonary hospital with locally advanced unresectable NSCLC and we evaluated them for baseline clinical factors, follow-up. Patients underwent concurrent immunotherapy with chemoradiotherapy or consolidative immunotherapy after chemoradiotherapy. Patients were classified based on initial site of progression (primary versus non-primary site). The study endpoints were progression-free survival (PFS) and time to death or distant metastasis (TDDM). Cox proportional hazards analysis was used to assess the factors affecting PFS and TDDM.ResultsThe median follow-up time for both groups was 26 months, and there was no significant difference in baseline clinical characteristics (P>0.05). The patients receiving concurrent immunotherapy (n=36) had a longer PFS than those receiving consolidative immunotherapy (n=42) (median 32.4 vs. 15.5 months; P<0.01). The TDDM was also longer in patients with concurrent immunotherapy than those with consolidative immunotherapy (median 57.3 vs. 31.0 months; P=0.01). Furthermore, in a subset of patients with initial site of progression at a non-primary-site, patients undergoing concurrent immunotherapy had longer PFS than those undergoing consolidative immunotherapy (median 22.7 vs. 11.9 months; P=0.03).ConclusionsConcurrent immunotherapy with chemoradiotherapy may be associated with improved disease progression outcomes as compared to consolidative immunotherapy following chemoradiotherapy.

Project description:BackgroundCirculating immune cells influence the efficacy of cancer therapy. This study aimed to investigate the prognostic values of different peripheral blood leukocyte (PBL) biomarkers in non-small lung cancer (NSCLC) patients treated with chemoradiotherapy.MethodsAn independent cohort of 176 stage III NSCLC patients who were diagnosed at Shanghai Pulmonary Hospital and Zhejiang Cancer Hospital between April, 2010, and September, 2018, and had available pretreatment peripheral blood tests was enrolled. The patients were all treated with concurrent or sequential chemoradiotherapy according to international clinical guidelines, with conventional fractionated radical radiotherapy. The receiver operating characteristic curve and the Youden index were used to determine the optional cutoff values of PBL biomarkers for distinguishing prognosis. Univariate and multivariate Cox proportional hazards regression analyses were performed to identify the factors significantly correlated with overall survival.ResultsThe cohort had a median follow-up time of 21.7 (3.1-121) months. The 3- and 5-year OS rates of all patients were 34.7% and 27.5%, respectively. Univariate analysis showed that gender (P=0.011), smoking (P=0.011), tumor-node-metastasis (TNM) stage (P=0.002), pretreatment peripheral blood neutrophil-to-leukocyte ratio (P=0.013), and systemic inflammation response index (SIRI, P<0.001) were all correlated with OS in NSCLC patients. Moreover, multivariate analysis revealed that TNM stage (HR =1.541, 95% CI: 1.166-2.036, P=0.010) and SIRI (HR =1.868, 95% CI: 1.016-3.436, P=0.018) were significantly and independently associated with OS. However, the median OS of stage IIIB NSCLC patients with low SIRI (≤2.0) was longer than that of stage IIIA NSCLC patients with high SIRI (>2.0) (33.9±4.1 vs. 19.6±2.5 months).ConclusionsPretreatment peripheral blood SIRI was found to be a simple independent predictor of OS in stage III NSCLC patients who underwent chemoradiotherapy. As a novel prognostic marker, the prognostic value of the SIRI is superior to that of the NLR. Low SIRI could be a better prognostic stratification factor for NSCLC patients with different TNM stages.

Project description:Background We compared cardiac outcomes for surgery-eligible patients with stage III non-small-cell lung cancer treated adjuvantly or neoadjuvantly with chemotherapy versus chemo-radiation therapy in the Surveillance, Epidemiology and End Results-Medicare database. Methods and Results Patients were age 66+, had stage IIIA/B resectable non-small-cell lung cancer diagnosed between 2007 and 2015, and received adjuvant or neoadjuvant chemotherapy or chemo-radiation within 121 days of diagnosis. Patients having chemo-radiation and chemotherapy only were propensity-score matched and followed from day 121 to first cardiac outcome, noncardiac death, radiation initiation by patients who received chemotherapy only, fee-for-service enrollment interruption, or December 31, 2016. Cause-specific hazard ratios (HRs) and competing risks subdistribution HRs were estimated. The primary outcome was the first of these severe cardiac events: acute myocardial infarction, other hospitalized ischemic heart disease, hospitalized heart failure, percutaneous coronary intervention/coronary artery bypass graft, cardiac death, or urgent/inpatient care for pericardial disease, conduction abnormality, valve disorder, or ischemic heart disease. With median follow-up of 13 months, 70 of 682 patients who received chemo-radiation (10.26%) and 43 of 682 matched patients who received chemotherapy only (6.30%) developed a severe cardiac event (P=0.008) with median time to first event 5.45 months. Chemo-radiation increased the rate of severe cardiac events (cause-specific HR: 1.62 [95% CI, 1.11-2.37] and subdistribution HR: 1.41 [95% CI, 0.97-2.04]). Cancer severity appeared greater among patients who received chemo-radiation (noncardiac death cause-specific HR, 2.53 [95% CI, 1.93-3.33] and subdistribution HR, 2.52 [95% CI, 1.90-3.33]). Conclusions Adding radiation therapy to chemotherapy is associated with an increased risk of severe cardiac events among patients with resectable stage III non-small-cell lung cancer for whom survival benefit of radiation therapy is unclear.
