Construction and validation of a nomogram of risk factors for new-onset atrial fibrillation in advanced lung cancer patients after non-surgical therapy. Front Oncol 2023; 13:1125592. [PMID: 37519821 PMCID: PMC10374250 DOI: 10.3389/fonc.2023.1125592] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Accepted: 06/28/2023] [Indexed: 08/01/2023] Open
Abstract
Objective Risk factors of new-onset atrial fibrillation (NOAF) in advanced lung cancer patients are not well defined. We aim to construct and validate a nomogram model between NOAF and advanced lung cancer. Methods We retrospectively enrolled 19484 patients with Stage III-IV lung cancer undergoing first-line antitumor therapy in Shanghai Chest Hospital between January 2016 and December 2020 (15837 in training set, and 3647 in testing set). Patients with pre-existing AF, valvular heart disease, cardiomyopathy were excluded. Logistic regression analysis and propensity score matching (PSM) were performed to identify predictors of NOAF, and nomogram model was constructed and validated. Results A total of 1089 patients were included in this study (807 in the training set, and 282 in the testing set). Multivariate logistic regression analysis showed that age, c-reactive protein, centric pulmonary carcinoma, and pericardial effusion were independent risk factors, the last two of which were important independent risk factors as confirmed by PSM analysis. Nomogram included independent risk factors of age, c-reactive protein, centric pulmonary carcinoma, and pericardial effusion. The AUC was 0.716 (95% CI 0.661-0.770) and further evaluation of this model showed that the C-index was 0.716, while the bias-corrected C-index after internal validation was 0.748 in the training set. The calibration curves presented good concordance between the predicted and actual outcomes. Conclusion Centric pulmonary carcinoma and pericardial effusion were important independent risk factors for NOAF besides common ones in advanced lung cancer patients. Furthermore, the new nomogram model contributed to the prediction of NOAF.

IA PULMONARY VEIN ATLAS FOR RADIOTHERAPY PLANNING. Radiother Oncol 2023; 184:109680. [PMID: 37105303 DOI: 10.1016/j.radonc.2023.109680] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 04/10/2023] [Accepted: 04/19/2023] [Indexed: 04/29/2023]
Abstract
BACKGROUND AND PURPOSE Cardiac arrhythmia is a recognised potential complication of thoracic radiotherapy, but the responsible cardiac substructures for arrhythmogenesis have not been identified. Arrhythmogenic tissue is commonly located in the pulmonary veins (PVs) of cardiology patients with arrhythmia, however these structures are not currently considered organs-at-risk during radiotherapy planning. A standardised approach to their delineation was developed and evaluated. MATERIALS AND METHODS The gross and radiological anatomy relevant to atrial fibrillation was derived from cardiology and radiology literature by a multidisciplinary team. A region of interest and contouring instructions for radiotherapy computed tomography scans were iteratively developed and subsequently evaluated. Radiation oncologists (n=5) and radiation technologists (n=2) contoured the PVs on the four-dimensional planning datasets of five patients with locally advanced lung cancer treated with 1.8-2.75 Gy fractions. Contours were compared to reference contours agreed by the researchers using geometric and dosimetric parameters. RESULTS The mean dose to the PVs was 35% prescription dose. Geometric and dosimetric similarity of the observer contours with reference contours was fair, with an overall mean Dice of 0.80 ± 0.02. The right superior PV (mean DSC 0.83 ± 0.02) had better overlap than the left (mean DSC 0.80 ± 0.03), but the inferior PVs were equivalent (mean DSC of 0.78). The mean difference in mean dose was 0.79 Gy ± 0.71 (1.46% ± 1.25). CONCLUSION A PV atlas with multidisciplinary approval led to reproducible delineation for radiotherapy planning, supporting the utility of the atlas in future clinical radiotherapy cardiotoxicity research encompassing arrhythmia endpoints.

Abstract
Atrial fibrillation remains one of the most common conditions that clinical physicians encounter on a daily basis in the inpatient setting. This arrhythmia brings with it numerous complications if not treated properly and leads to intensive analysis of its primary etiology which is unique to every patient. In this case, we present a previously asymptomatic individual who presented to the hospital with respiratory complaints and was found to have a large lung mass, consistent with neuroendocrine lung cancer with direct compression of the left atrium leading to new-onset atrial fibrillation.

Abstract
Many factors contribute to mortality in lung cancer, including the presence of concomitant cardiovascular disease. In the treatment of early stage of lung cancer, the presence of comorbidities and occurence of cardiotoxicity may be prognostic. The effect of cardiotoxicity of radiotherapy and chemoradiotherapy on overall survival has been documented. Acute arterial and venous thromboembolic events seem to correlate with the degree of the histological malignancy, its clinical advancement, and even with optimal cardiac treatment, they may influence the survival time. In the case of high-grade and advanced lung cancer stage especially in an unresectable stadium, the prognosis depends primarily on the factors related to the histopathological and molecular diagnosis. Electrocardiographic and echocardiographic abnormalities may be prognostic factors, as they seem to correlate with the patient's performance status as well as tumor localization and size.

Refractory Atrial Fibrillation With Rapid Ventricular Rate in a Patient With Small Cell Carcinoma of the Lung Encasing the Right Pulmonary Artery: A Case Report and Insight Into Therapeutic Options. Cureus 2021; 13:e16027.

Abstract
Atrial fibrillation is the most common sustained cardiac arrhythmia. While there have been reports of atrial fibrillation caused by the compression of pulmonary veins, we have not found reports of atrial fibrillation caused by the compression of the pulmonary artery. This report highlights the possible pathophysiology and management of atrial fibrillation in a patient with small cell lung cancer. The patient was admitted for hyponatremia secondary to syndrome of inappropriate antidiuretic hormone (SIADH) but subsequently developed tachycardia which progressed to atrial flutter and atrial fibrillation. Antiarrhythmics were ineffective until the patient received his first palliative chemotherapy for his small cell lung cancer. Subsequently, rate control was achieved with sotalol, with eventual conversion back to sinus rhythm. Management of atrial fibrillation is complex and sometimes depends on the underlying etiology. Early chemotherapy, in addition to antiarrhythmic drugs, may be beneficial in the management of patients with small cell lung cancer and atrial fibrillation. The CHA2DS2-VASc score does not take active malignancy into account and anti-coagulation should be evaluated on a case-by-case basis in this patient population.
