Objective To investigate the clinical characteristics of primary malignant tumors of the left atrium and the late results of surgical treatment. Methods The clinical experience with surgical treatment of 13 primary malignant tumors of left atrium was analyzed retrospectively. Complete resection of malignant tumor was achieved in 7 cases(53.8％ )，and subtotal resection was achieved in 3 cases(23.0％), only biopsy was performed in 2 patients(15.4％ )because of extensive metastasis of tumor. Heart transplantation was performed in 1 case(7.7％). Results There was no hospital death. The pathological diagnosis was undifferentiated sarcoma in 5 cases, leiomyosarcoma in 2 cases, malignant transformation of myxoma in 2 cases, angiosarcoma in 1 case, fibrosarcoma in 1 case, malignant fibrous histocytoma in 1 case and malignant hemangiopericytoma in 1 case. There were 11 patients followedup for 3 months to 65 months and showed 9 late death due to recurrence or metastasis. There was 2 patients lost of follow-up. Conclusion Primary malignant tumors of the left atrium should be resected to relieve symptoms caused by local tumor growth. Surgery provides control of primary tumor and allows the potential for cure or longterm survival with effective adjuvant therapy. The prognosis of these patients is still poor.
Primary cardiac tumors, which originate from the heart, are uncommon and can be classified as benign or malignant, with the majority being benign. Malignant primary cardiac tumors have a poor prognosis. Benign ones may also cause severe hemodynamic and electrophysiological consequences, but the prognosis is generally good if they are detected early and treated properly. In recent years, researches on the genetic and molecular causes of primary cardiac tumors have yielded some promising breakthroughs, with some of them already being translated into clinical practice. This article reviews research progress and its use in precise diagnosis and targeted therapy from the perspective of DNA, RNA, and protein changes, as well as prospects the promising research directions in the future.
Objective To explore the diagnosis accuracy of cardiac tumor and effectiveness of surgical treatment. Method We retrospectively analyzed the clinical data of 103 patients with cardiac tumor in our hospital from 2011 through 2014 year. There were 65 females and 38 males, aging from 3 months to 82 years (average age of 59.71±13.80 years). We analyzed age distribution and clinical manifestation of the patients, as well as size and location of tumors. Then we compared effects of different surgical procedures. Result There was no death during evaluation. Early postoperative complications included arrhythmia (47 patients), electrolyte disturbance (13 patients), and cardiac dysfunction (9 patients). One patient with B-cell non-Hodgkin's lymphoma auto-discharged because of cardiac dysfunction. No relapse was obse-rved in the patients with atrial myxoma or lipoma (2 patients) during follow-up. One patient with benign myogenic tumor was lost during the follow-up. Six patients with malignant tumor were with poor long-term effect including 2 patients lost in the follow-up and 4 deaths due to tumor relapse during 1 year after surgery. Conclusion Surgery is still the most effective and major therapy of cardiac tumor.
ObjectiveTo analyze the clinical characteristics and surgical treatment results of cardiac tumors.MethodsClinical data of 28 patients with cardiac tumors, who underwent cardiac surgery in our hospital from 2013 to 2019 were retrospectively reviewed. There were 12 males and 16 females. The median age was 11.5 years, ranging 1 month to 69 years; and the median weight was 39.0 (4.8-100.0) kg. All patients underwent tumor resection under cardiopulmonary bypass with general anesthesia, and postoperative pathological analysis was performed.ResultsThere were 27 patients with primary cardiac tumors and 1 patient with secondary cardiac tumor. Among the primary cardiac tumors, there were 16 myxomas, 5 rhabdomyomas, 3 inflammatory myofibroblastomas, 2 fibroids and 2 hemangiomas. The secondary cardiac tumor was chondrosarcoma. A total of 28 cardiac tumors occurred in 29 locations, including 14 in the left atrium, 3 in the right atrium, 1 in the left ventricle, 7 in the right ventricle, 2 in the mitral and 2 in the tricuspid. Cerebral embolism occurred in 6 patients, peripheral vascular embolism in 3 patients, and syncope in 3 patients. There was no death during the perioperative period and in the long term follow-up. Complete resection was performed in 25 patients and partial resection was performed in 3 patients. During the follow-up, 2 patients with myxoma received reoperation for recurrence. Among the 3 patients with partial resection, residual tumor tissue disappeared in 2 patients, and in the other patient, there was no change in the size of the residual tumor tissue during the follow-up compared to that at discharge.ConclusionCardiac surgery is an effective method for patients with primary benign cardiac tumors. However, whether the cardiac tumor tissue can be completely removed depends on the anatomical location of the tumor during the operation. If there are systemic embolism events and syncope, the possibility of cardiac tumors should be considered.
