title: [A clinical analysis of 10 cases with cardiac lymphoma].
abstract: Objective:To analyze the morbidity, clinical characteristics, therapeutic outcomes and prognosis of cardiac lymphoma.Methods:Individual patient data were obtained from pathology defined 10 cases of cardiac lymphoma from Jan 2000 to Jun 2016. The patient's general information, clinical manifestation, pathological diagnosis, laboratory examination, cardiac involvement feature, cardiac complications, treatment, therapeutic effect and prognosis were analyzed.Results:Of 3 918 cases of lymphoma patients, 10 cases of cardiac involvement were identified, including primary cardiac lymphoma (PCL) in 1 case, secondary cardiac lymphoma (SCL) in 9 cases. Of the 10 patients in our analysis, the male-to-female ratio was 3∶2, with a median age of 55 (19-88) years old. The most presenting complaints were dyspnea in 7 cases, followed by chest pain in 5 cases, fatigue in 2 patients and edema in 2 cases. Pathological types included diffuse large B cell lymphoma (DLBCL) in 7 cases, T cell lymphoma (T-LBL) in 1 case, Hodgkin's lymphoma (HL) in 1 case, and Burkitt lymphoma (BL) in 1 case. The sites of the heart affected by lymphoma in the PCL patient were right and left atriums with multiple nodules; and for SCL, the sites were mainly pericardium associated with a pericardial effusion in 5 cases, a pericardial mass in 2 cases. Congestive heart failure affects 7 patients and cardiac arrhythmias were identified in 4 cases mainly sinus tachycardia, atrial fibrillation and atrioventricular block. Except one untreated because of old age and poor performance, the rest of 9 patients were treated by either chemotherapy in 4 cases or chemotherapy combined radiotherapy (including the extracardiac sites) in 5 patients. With the median follow-up of 9 months, the one PCL patient achieved partial response (PR) , progress free survival (PFS) for 6 months and the overall survival (OS) for 21 months; in the cohort of 6 SCL patients cardiac involved at diagnosis, complete response (CR) was achieved in 1 case (16.7%) , PR in 3 cases, progressing disease (PD) in 2 cases, with the median PFS for 5 months and the median OS for 19 months; and for the other 3 SCL patients cardiac involved at progression, PR was achieved in 2 case and death in 1 case, with the median PFS for 4 months and the median OS unavailable because of censored data.Conclusion:Cardiac lymphoma represents a rare subset of lymphoma, the most common type is DLBCL, and the main clinical manifestations are dyspnea and chest pain, always combined by arrhythmia and congestive heart failure. The main therapeutic regimen for cardiac lymphoma includes combined chemotherapy and the prognosis for patients with either PCL or SCL is usually poor.
