Laterality in Renal Cancer: Effect on Survival in Veteran Population
Background
Kidney and renal pelvis cancers (KC) represent 4% of new cancer cases in the US. Although it is a common cancer, there is no data to compare the effect of laterality on survival in veteran population. In this abstract, we attempt to bridge this gap and compare the effect of laterality on survival.
Methods
We obtained data from Albany VA (VAMC) for patients diagnosed with KC between 2010-2020. Data were analyzed for age, stage at diagnosis, histopathological type, laterality of tumor, and 6,12 and 60-months survival after the diagnosis and performed a comparison of overall survival of left versus rightsided cancer by calculating odds ratio using logistic regression, significance level was established at p< 0.05.
Results
We reviewed 130 patients diagnosed with KC at VAMC. 62 had right-sided, 62 had left-sided, and 6 had bilateral cancer. Clear cell (40.8%) was predominant type. Other less common histopathological types include Papillary RCC, mixed, papillary urothelial and transitional types. 58 patients had stage 1 (28 right versus 30 left), 8 had stage 2 (5 versus 3), 29 had stage 3 (13 versus 16), 16 with stage 4 (12 versus 4), and 14 had stage 0 (papillary-urothelial). 59.2% patients underwent surgical treatment after diagnosis (R=35, L=39). At 6-months, 60 patients (96.8%) with left-sided and 53 (85.5%) with right-sided cancer survived. The odds of surviving 6-months were 12% higher (95% CI: 1.014, 1.236; p=0.03) in left versus right-sided cancer. For 1-year survival, the results were similar. 111 patients completed a 5-year follow-up and there was no evidence to support a difference in survival between cohorts at 5-years: OR (95% CI: 0.88, 1.47; p=0.32).
Conclusions
In this study, we discovered that leftsided cancer showed better survival at 6-months and 1-year compared to right-sided cancer, but 5-year survival rates appeared similar irrespective of laterality of cancer. Both subgroups had similar distribution for baseline characteristics with majority of patients being males, older than 60 years, with stage 1 disease. Further studies in larger populations with wider distribution of baseline characteristics are needed to establish clear role of laterality as a prognostic factor.

A Single-Center Experience of Cardiac-related Adverse Events from Immune Checkpoint Inhibitors
Introduction
There have been incident reports of cardiac-related adverse events (CrAE) from immune checkpoint inhibitors (ICPI); however, the true incidence and subsequent management of these potential side effects have not been defined. It is therefore important to study ICPI related cardiac dysfunction to assist in monitoring and surveillance of these patients.
Methods
63 patients who received nivolumab and pembrolizumab at Stratton VAMC Albany between January 2015 to December 2018 were studied. Retrospective chart review was done to identify the CrAE up to two-year post-therapy completion or discontinuation. Naranjo score was used to assess drug-related side effect. IRB approval was obtained.
Results
CrAE were defined as new onset arrythmia identified on electrocardiogram, evidence of cardiomyopathy on echocardiogram, an acute coronary event, and hospitalizations from primary cardiac disorder following ICPI administration. Of the 63 patients, 6 patients developed CrAE. Our review showed 3 patients developed new arrythmias including 1 with atrial fibrillation, and 2 with atrial flutter. There was 1 case each of new heart failure with reduced ejection fraction and pericarditis with pericardial tamponade. 1 patient developed acute coronary syndrome in addition to complete heart block. Of the 6 patients, 2 had elevated brain natriuretic peptide (BNP) prior to onset of CrAE. Elevated markers including BNP and troponin-I were also seen in 13 patients with preexisting heart conditions without CrAE. Duration of therapy was variable for all patients with CrAE. Therapy was continued for 3 patients without recurrence of CrAE. Therapy was permanently discontinued in the patient who developed pericardial effusion (grade IV toxicity). The remaining 2 patients had additional concurrent immune-related toxicities that required discontinuation of therapy. Our analysis showed 25/63 patients with pre-existing cardiac conditions (including arrhythmia, heart failure or coronary artery disease) who did not develop new CrAE; however 6 of these patients required hospitalization for exacerbation related to these pre-existing conditions.
Conclusions
CrAE can occur with ICPIs, and vigilance is required in high-risk patient including those with pre-existing cardiac comorbidity. Further studies are required to establish if baseline screening EKG and echocardiogram should be obtained for all patients starting ICPI.
