Clinical characteristics and surgical outcomes of cardiac myxoma: A meta-analysis of worldwide experience.

Cardiac myxoma is the most common primary cardiac tumor. However, existing literature mainly consists of single-center experiences with limited subjects. This systematic review aimed to provide data on clinical characteristics and surgical outcomes of cardiac myxoma. We performed a thorough literature search on May 23, 2023 on PubMed, ProQuest, ScienceDirect, Scopus, and Web of Science. The inclusion criteria were English full-text, observational studies, and included >20 subjects. From the search, 112 studies with a total of 8150 patients were included in the analysis. The mean age was 51 years (95 % confidence interval [95%CI] = 49.1-52.3), and the majority were females (64.3 % [95 % CI = 62.8-65.8 %]). The most common clinical manifestation was cardiovascular symptoms. Echocardiography can diagnose almost all cases (98.1 % [95 % CI = 95.8-99.6 %]). Cardiac myxoma was mostly prevalent in left atrium (85.3 % [95%CI = 83.3-87 %]) and predominantly with pedunculated morphology (75.6 % [95%CI = 64.1-84.3 %]). Post-tumor excision outcomes were excellent, with an early mortality of 1.27 % (95 % CI = 0.8-1.8 %), late mortality rate of 4.7 (95 % CI = 2.5-7.4) per 1000 person-years, and recurrence rate at 0.5 (95 % CI = 0.0-1.1) per 1000 person-years. Tumor excision is warranted in a timely manner once the cardiac myxoma diagnosis is established.

Malignant cardiac neoplasms and associated malignancies over 16 years in the USA.

BACKGROUND: Malignant cardiac neoplasms (MCNs), both primary and metastatic, are rare with few epidemiologic studies. METHODS: This retrospective study used the Healthcare Utilization Project/Nationwide Inpatient Sample database from 2002 to 2018 to evaluate the co-occurrences with other malignancies, and mortality of MCNs in the USA. RESULTS: The data contained 7207 weighted discharges of MCN. Median patient age was 51.4 years, 52.29 % were male, in-hospital mortality was 10.51 %, mean cost of hospitalization was $34,280 USD. Lung, mediastinum, and airways were the most common primary cancers associated with metastatic MCN. CONCLUSIONS: MCN are rare in the USA, however they carry a high in-hospital mortality, high morbidity, and hospital cost.

Series of patients operated for masses and cysts in the heart in a Spanish general hospital: A 20-year experience.

BACKGROUND: Masses and cysts in the heart are well-known entities, but their low prevalence and non-specific symptoms makes the diagnosis difficult. We aimed to characterize the features of these entities in our environment. METHODS: We carried out a search of patients who underwent surgery for tumors and cysts in the heart between 2002 and 2022 in the registry of the Department of Cardiology and Cardiac Surgery of Clínica Universidad de Navarra (Pamplona, Spain). Sociodemographic, clinical, histological, and surgical variables were collected. RESULTS: We identified 13 patients; mean age was 63.08 ± 15.17 years, 76.92% were female and 92.31% had at least one cardiovascular risk factor, e.g., BMI = 25 kg/m2 and high blood pressure (61.54% and 53.85%, respectively). The most common type of cardiac tumors were myxomas (69.23%). Around half (46.15%) were incidental; the most frequent symptom was dyspnea (53.85%); 30.77% of the patients were asymptomatic. The most commonly used imaging technique for the diagnosis was transthoracic Doppler echocardiography (69.23%). The agreement between the mean diameters before and after surgery was very high (ICC = 0.807, 95% CI: 0.450 - 0.943). CONCLUSIONS: We describe the features of masses and cysts in the heart (77% female patients) and provide information scarcely available in the literature, e.g., the most frequent cardiovascular risk factors for this population. A case of cardiac leiomyosarcoma and a case of intimal sarcoma of the pulmonary trunk are described, two extremely rare tumors for which there are few described cases.

Survival and analysis of prognostic factors for primary malignant cardiac tumors based on the SEER database.

PURPOSE: The purpose of this study was to use the Surveillance, Epidemiology, and End Results (SEER) database to evaluate the survival rate of primary malignant cardiac tumors (PMCTs), assess the risk factors affecting survival, and calculate the number of PMCT cases in recent years. METHODS: SEER 22 registries were used to calculate the number of cases PMCT. Data on age, sex, race, marital status, tumor size, the American Joint Committee on Cancer (AJCC) stage, lymph node involvement, metastasis, treatment, and survival were collected to analyze the survival and prognostic factors of SEER 17 registries. Using the Kaplan-Meier estimation method, a survival curve was obtained according to the influencing factors, and a multivariable Cox regression model was established. RESULTS: In recent years, the average annual number of PMCT cases was 20.56 ± 7.12, significantly higher than the average before 2004 (P = 0.015; 95% CI 1.14-8.98). The 1-, 3-, and 5-year survival rates were 45.6%, 18.8%, and 11.2%, respectively. Multivariate analysis revealed that age (risk ratio [HR], 2.047; 95% CI 1.381-3.034), AJCC stage III (HR, 1.786; 95% CI 1.123-2.839), AJCC staging with distant metastasis (HR, 2.666; 95% CI 1.509-4.709), no chemotherapy (HR, 2.011; 95% CI 1.561-2.590), and tumor size larger than 99 mm (HR, 1.766; 95% CI 1.132-2.756) were independent risk factors for poor prognosis. Only age over 76 years and distant metastasis were independent risk factors for prognosis in the chemotherapy group. CONCLUSION: In recent years, the annual number of patients with PMCT has increased significantly. Due to developments in chemotherapy, we should re-evaluate the traditional tumor staging and prognostic risk indicators to improve clinical applications.

Surgical experience in cardiac myxomas at a tertiary hospital.

INTRODUCTION: Cardiac myxomas account for 50% of all benign cardiac tumors. Their clinical presentation varies from embolisms to fever. Our objective was to describe the surgical experience in the resection of cardiac myxomas during an 8-year period. METHODS: This is a retrospective, descriptive study of a series of cases with cardiac myxomas diagnosed from 2014 to 2022 at a tertiary care center. Descriptive statistics were used to define the populational and surgical characteristics. We used Pearson's correlation to study the relationship between postoperative complications and age, tumor size and affected cardiac chamber. RESULTS: 31 patients were included, with a predominance of females (1:2 ratio). The prevalence was 0.44%, which was calculated based on the number of cardiac surgeries performed in our unit over the 8-year period. The main clinical manifestation was dyspnea (85%, n = 23), followed by cerebrovascular event (CVE) (18%, n = 5). Atriotomy and resection of the pedicle were performed with preservation of the interatrial septum. Mortality was 3.2%. The postoperative evolution was uneventful in 77%. Tumor recurrence occurred in 2 patients (7%), both debuting with embolic phenomena. No association was observed between postoperative complications or recurrence and tumor size, nor aortic clamping and extracorporeal circulation times with regard to age. CONCLUSIONS: Four atrial myxoma resections are performed in our unit per year, with an estimated prevalence of 0.44%. The tumor characteristics described coincide with the previous literature. A relationship between embolisms and recurrences cannot be ruled out. Wide surgical resection of the pedicle and base of tumor implantation may influence tumor recurrence, although further studies are needed.

[Cardiac tumors in clinical practice]. / Les tumeurs cardiaques.

Cardiac tumors are rare in clinical practice but remain an essential part of the fast-growing field of cardio-oncology. They can be detected incidentally and consist of primary tumors (benign or malignant) and of the more prevalent secondary tumors (metastasis). They form a heterogeneous group of pathologies presenting with a wide panel of clinical symptoms according to their location and size. Multimodality cardiac imaging (echocardiography, CT, MRI and PET), in association with clinical and epidemiological factors, plays a key role in the diagnosis of cardiac tumors and a biopsy is therefore not systematically required. Treatment strategies for cardiac tumors vary depending on the malignancy and class of the tumor, but also consider associated symptoms, hemodynamic impact and embolic risk.

Les tumeurs cardiaques sont des pathologies rares mais elles ­appartiennent à un domaine en plein essor de la cardio-oncologie. Souvent découvertes fortuitement, elles comprennent les ­tumeurs cardiaques primaires (bénignes ou malignes) et, plus fréquemment, secondaires (métastases). Elles constituent un ­ensemble très hétérogène de pathologies, dont les manifestations cliniques varient en fonction de la taille et de la localisation. Le diagnostic repose sur une approche clinique, épidémiologique et plusieurs modalités d'imagerie (échocardiographie, CT, IRM et PET-CT), sans nécessité systématique de biopsie. La stratégie de traitement d'une tumeur cardiaque dépend de la symptomatologie du patient, du risque embolique ou hémodynamique lié à la masse, ainsi que de sa malignité.

Cardiac Metastasis From Solid Cancers: A 35-Year Single-Center Autopsy Study.

CONTEXT.­: Cardiac metastases are more prevalent than primary cardiac tumors, and although rare, the incidence is anticipated to increase with the extended survival of oncology patients. OBJECTIVE.­: To estimate the current incidence of cardiac metastasis from solid tumors in adult autopsies. DESIGN.­: Adult autopsy cases from 1984 through 2019 from patients diagnosed with any type of solid cancer were retrieved. The medical charts and pathologic autopsy data were reviewed in detail. RESULTS.­: A total of 1294 adult autopsies performed on patients diagnosed with any type of cancer within the past 35 years were reviewed. We found 124 secondary cardiac tumors. Eighty-five were due to cardiac involvement by solid tumors. Of these, 61 were true cardiac metastases of solid cancers. We focused on these 61 cases. The age range was 32 to 85 years. Forty-four patients were men and 17 were women. The lung was the most common primary site, with 21 cases (34.43%). The most frequent histologic type was carcinoma, with 54 cases (88.52%). The predominant layer of the heart involved was the pericardium, with 35 cases (57.38%). Twenty-one cases (34.43%) had pericardial effusion, with 4 being hemorrhagic. All cases had multiple extracardiac metastases, with 56 cases (91.8%) having distant metastases in 4 or more different organs. CONCLUSIONS.­: Cardiac metastasis is a rare occurrence, with an incidence of 4.71% (61 of 1294 cases) in our series. Lung cancer accounted for most of the cardiac metastases seen, and carcinomas were the most frequent histologic type. The pericardium was the most frequent location. Cardiac metastases occurred most frequently in cases of massive metastatic dissemination.

Cardiac Masses (from a 15-Year Experience With 389 Surgical Cases).

Cardiac masses are highly heterogeneous and vary widely in their clinical presentation, imaging features, and survival outcomes. Our understanding is limited by their rarity and the fact that few are confirmed based on surgical pathology. We set out to provide a comprehensive analysis of all cardiac masses resected at our institution from 1999 to 2015, including imaging methods and histopathologic findings. We found papillary fibroelastomas (PFEs) to be the most commonly resected benign cardiac masses, followed by myxomas. Patients with PFEs most frequently presented with cerebrovascular accidents and transient ischemic attacks, whereas those with myxomas were more likely to present with arrhythmias and palpitations. In contrast, primary malignant cardiac masses were much rarer; angiosarcoma was the predominant subtype with a poor prognosis. Renal cell carcinomas were the most commonly discovered primary cancer for metastatic cardiac masses, and calcified amorphous tumors were the most prevalent non-neoplastic masses. For the detection of cardiac masses, transthoracic echocardiography was the most frequently used but least sensitive of the imaging methods analyzed. Transesophageal echocardiography (TEE) was the most sensitive imaging method. Fluorodeoxyglucose Positron Emission Tomography had similar sensitivity to TEE but was the least frequently used imaging method. Computed tomography and magnetic resonance imaging performed well in detecting most masses; PFEs, for which TEE was the most sensitive, was the exception. In conclusion, we found that PFEs were the most commonly resected benign cardiac masses, and TEE was the most accurate imaging method for the detection of all surgically removed masses at our institution.

Cardiac myxoma: single tertiary centre experience.

BACKGROUND: Although cardiac myxoma (CM) are rare and benign, they can cause life-threatening complications, such as hemodynamic disturbances or embolization. Surgical excision of the tumour is the treatment of choice. The aim of the study was to evaluate the epidemiological characteristics, clinical presentation, imaging findings, and outcomes of surgical treatment of patients with CM treated in the largest tertiary care centre in Slovenia. PATIENTS AND METHODS: We retrospectively analysed the medical records of all patients referred to our institution between January 2005 and December 2020 and identified 39 consecutive adult patients with pathologically confirmed CM. RESULTS: The average annual incidence of CM in the study was 3 per 2 million population per year. Patients were more often female (n = 25, 64%). The mean age at diagnosis was 63.1 ± 13.6 years. Dyspnoea was the most common presenting symptom (31%). CM was an incidental finding in 11 patients (28%). Seven patients presented with thromboembolic event (18%). Transthoracic echocardiography (TTE) was performed in all patients, however additional imaging was required in 22 patients (56%). All patients in our series were successfully treated surgically without in-hospital mortality. During the follow-up period (6 months to 16 years) three patients (8%) died, and all deaths were unrelated to CM. There was no recurrence of CM during the follow-up. CONCLUSIONS: Our single-centre study confirms that CM is rare cardiac tumour with diverse clinical presentation. Our data shows data that CM might be more prevalent than considered before. Surgical resection of the tumour is safe with excellent short- and long-term outcomes.

National outcomes following benign cardiac tumor resection: A critical sex-based disparity.

BACKGROUND: Treatment of benign primary cardiac tumors involves surgical resection, but reported outcomes from multi-institutional or national databases are scarce. This study examines contemporary national outcomes following surgical resection of benign primary atrial and ventricular tumors. METHODS: The 2016-2018 Nationwide Readmissions Database was queried for all patients ≥18 years with a primary diagnosis of benign neoplasm of the heart who underwent resection of the atria, ventricles, or atrial/ventricular septum. Primary outcomes were 30-day mortality, readmission, and composite morbidity (defined as stroke, permanent pacemaker implantation, bleeding complication, or acute kidney injury). Multivariable analysis was used to identify independent predictors of worse outcomes. RESULTS: A weighted total of 2557 patients met inclusion criteria. Mean age was 61 years, 67.9% were female, and patients had relatively low comorbidity burdens (mean Charlson Comorbidity Index 1.39). The majority of patients underwent excision of the left atrium (71.5%), followed by the intra-atrial septum (26.6%), right atrium (2.9%). There was no difference in 30-day mortality (2.1% vs. 1.3%, p = .550), 30-day readmission (7.0% vs. 9.1%, p = .222), or 30-day composite morbidity (56.8% vs. 53.8%, p = .369) between females and males, respectively. However, on multivariable analysis, female sex was independently associated with increased risk of 30-day mortality (adjusted odds ratio = 2.65, p = .028). Tumor location (atria, ventricles, septum) was not predictive of mortality. CONCLUSION: Benign atrial and ventricular tumors are uncommon, but disproportionately impact female patients, with female sex being an independent predictor of 30-day mortality. Root-cause analysis is necessary to determine the ultimate cause of this disparity.

Linfoma cardiaco primario / Primary cardiac lymphoma

Los tumores cardíacos primarios son raros. Tienen una incidencia que varía entre 1,38 y 30 por 100.000 personas al año, un aproximado de 75-80 por ciento son benignos. El linfoma cardíaco primario representa el 1,3 por ciento de los tumores cardíacos primarios y el 0,5 por ciento de los linfomas extranodales. Se define como un linfoma no Hodgkin (LNH) que afecta solo al corazón y/o el pericardio. Su complejo sintomático puede incluir disnea, dolor torácico, fatiga progresiva, sudoración nocturna, pérdida ponderal, arritmias, síndrome de vena cava superior y un aproximado del 20 por ciento de los pacientes pueden desarrollar insuficiencia cardíaca aguda como primera manifestación. Sin embargo, la mayoría de ellos cursan con sintomatología inespecífica y son detectados de manera incidental. El linfoma no Hodgkin difuso de células B grandes es la variante histológica más frecuente. Presentamos un caso que inició con síntomas de insuficiencia cardiaca derecha, evolucionó desfavorable hasta su fallecimiento y se realizó el diagnóstico en la autopsia(AU)

Primary cardiac tumors are rare. They have an incidence that varies between 1.38 and 30 per 100,000 people per year, 75-80 percent are benign, approximately. Primary cardiac lymphoma represents 1.3 percent of primary cardiac tumors and 0.5 percent of extranodal lymphomas. It is defined as a non-Hodgkin's lymphoma (NHL) affecting only the heart and/or the pericardium. Its symptoms may include dyspnea, chest pain, progressive fatigue, night sweats, weight loss, arrhythmias, and superior vena cava syndrome. Approximately 20 percent of patients may develop acute heart failure as the first manifestation. However, most of them have nonspecific symptoms and are detected incidentally. Diffuse large B-cell non-Hodgkin's lymphoma is the most frequent histological variant. We report a case that began with symptoms of right heart failure, progressed unfavorably until death, and the diagnosis was made at autopsy(AU)

Cardiac Myxoma among Patients Undergoing Cardiac Surgery in a Tertiary Care Center: A Descriptive Cross-sectional Study.

INTRODUCTION: Heart neoplasms are rare tumors. Myxoma is the commonest primary benign tumor of the heart presenting with features of obstruction, arrhythmia, and embolism. Surgical excision of the tumor is the gold standard of treatment. The aim of the study is to find out the prevalence of cardiac myxoma among all cardiac surgeries operated during the study period. METHODS: A descriptive cross-sectional study was done among 3800 patients undergoing surgery for cardiac tumors in a tertiary care center after obtaining approval from the Institutional Review Committee (Reference number- 36/(6-11)E2/077/078). The data was collected retrospectively from August 2012 to August 2020 using convenience sampling method. Statistical analysis was performed using Microsoft Excel 2016. Point estimate at 95% Confidence Interval was calculated along with frequency, percentage, mean and standard deviation. RESULTS: There were 26 (0.68%) (0.42-0.94 at 95% Confidence Interval) myxoma among 3800 cardiac surgeries performed over eight years. The mean age of the patients was 54.76±14.31 (range 17-75) years. Twenty (76.92%) patients were females. The commonest presenting symptom was shortness of breath in 19 (73.07%) patients. En masse excision with the closure of the atrial septal defect was the principal surgical technique. The mean Intensive Care Unit stay and hospital stays were 2.92±1.29 and 6.26±2.61 days respectively. There was no perioperative mortality. CONCLUSIONS: Cardiac myxoma was the most common cardiac tumor encountered as in other studies.

Sex differences in primary malignant cardiac tumors: A multi-institutional cohort study from National Cancer Database.

INTRODUCTION: Despite the significant clinical importance of sex among factors affecting cancer progression and survival, it remains one of the least studied factors. Therefore, we sought to examine these differences in relation to primary malignant cardiac tumors (PMCTs) using a national data set. METHODS: The 2004-2017 National Cancer Database was queried for patients with PMCTs. Annual trend of females' percent was assessed. Overall survival predictors were evaluated with Kaplan-Meier and Cox-regression. Subgroup analysis was done based on histology, comorbidity index, race, insurance, and surgical treatment. RESULTS: PMCTs were identified in 736 patients (median age 52, female [47.8%]). Most of them were high-grade (49.2%). About 60% underwent surgery. Angiosarcoma (43%), fibrosarcoma (5.2%), and leiomyosarcoma (5.2%) were the most common pathologies. Based on multivariate Cox-regression, higher income, higher comorbidity index, angiosarcoma, and Stage III/IV were associated with higher late mortality, while year of diagnosis and use of surgery or chemotherapy were associated with lower mortality. Among the surgical group, age, higher income, higher comorbidity index, angiosarcoma, and Stage III/IV were independent predictors of higher late mortality, while private insurance and year of diagnosis were associated with lower late mortality. No difference was seen between males and females in 30-day and late mortality (p = .71). Subgroup analysis based on Cox-regression showed no differences in late mortality between males and females. CONCLUSION: PMCTs have poor overall survival. Surgery and chemotherapy were associated with longer survival benefits. On the contrary, the associated risk factors for mortality were advanced age, higher comorbidity index, angiosarcoma histology, and Stage III/IV.

Clinical and echocardiographic characteristics of patients with pathology proven right-sided papillary fibroelastomas.

BACKGROUND: Papillary fibroelastoma (PFE) are one of the most common primary cardiac neoplasms. They are most commonly found on cardiac valves especially on the left side of the heart and have been associated with an increased risk of embolization. To date, no large studies looked at the clinical significance of right-sided PFE (R-PFE). Therefore, we sought to better characterize patients with R-PFE and its clinical sequelae. METHODS: We retrospectively identified patients with pathology-proven PFEs at a single center between January 1995 and December 2018 (n = 279). Patients with R-PFE were analyzed. Medical records and echocardiograms were reviewed for clinical and PFE characteristics. RESULTS: Twenty-nine patients with R-PFE (mean age 70 ± 11 years; 62% women) were included in the analysis. PFEs were located on the right atrial (RA) wall in 31%, tricuspid valve in 34%, right ventricular (RV) wall in 7%, RV outflow tract in 4%, and pulmonary valve in 10% of patients. The remaining patients (14%) had multifocal PFEs. Around 38% of patients had cancer diagnosed before PFE diagnosis, and 34% had associated congenital heart disease. Seventeen (59%) patients had angina or dyspnea at the time of the presentation, and 3 (10%) had embolic symptoms. One patient with PFE located on the RA with associated patent foramen ovale had a stroke at time of presentation. Two patients, one with PFE on the RA wall and another patient with PFE at the tricuspid valve, had pulmonary embolism at the time of presentation. Median maximal length for PFE varied by location, ranging from a media of 8 mm to 16 mm. Of the 12 patients with follow up echocardiogram 1 year after PFE removal; 3/12 (25%) had documented PFE recurrence. CONCLUSION: R-PFE can be present in patients thromboembolic events when there is a right-to-left shunt. They can be a rare cause of pulmonary embolism, and at least in those that had follow-up echocardiograms, had a significant recurrence rate.

Long-term outcomes of primary cardiac malignant tumors: Difference between African American and Caucasian population.

BACKGROUND: The survival outcome for primary cardiac malignant tumors (PMCTs) based on race has yet to be fully elucidated in previously published literature. This study aimed to address the general long-term outcome and survival rate differences in PMCTs among African Americans and Caucasian populations. METHODS: The 18 cancer registries database from the Surveillance, Epidemiology, and End Results (SEER) Program from 1975 to 2016 were utilized. Ninety-four African American (AA) and 647 Caucasian (CAU) patients from the SEER registry were available for survival analysis. The log-rank test was used to compare the difference in mortality between two populations and presented by the Kaplan-Meier curves. A multivariate Cox proportional hazards regression was used to determine the independent predictors of all-cause mortality. RESULTS: The overall 30-day, 1-year, and 5-year survival rates were 74%, 44.3%, and 16.6%, respectively, with a median survival of 10 months. There was no significant difference in survival rate between the two races (p-value = 0.55). The 1-year survival rate improved significantly during the study timeline in the AA population (13.3% during 1975-1998, 40.9% during 1999-2004, 50% during 2005-2010, and 59.7% during 2011-2016, p-value = 0.0064). Age of diagnosis, type of tumor, disease stage, and chemotherapy administration are the main factors that predict survival outcomes of PMCT patients. Interactive nomogram was developed based on significant predictors. CONCLUSIONS: PMCTs have remained one of the most lethal diseases with poor survival outcome. Survival rate improved during the timeline in AA patients, but in general, racial differences in survival outcome were not observed.

Benign Cardiac Neoplasms in the United States: A Thirteen-Year Review.

Cardiac neoplasms are uncommon tumors. For epidemiological purposes, they can be divided into benign and malignant subtypes, with the former occurring at a significantly higher rate than the latter. Due to their uncommon nature, there are few data-driven studies examining the characteristics and trends of benign cardiac neoplasms. Our retrospective HCUP-NIS data review purports to illuminate some of the trends surrounding benign cardiac neoplasms and their associated co-occurrences. The data consisted of 482,872,274 weighted discharges. There were 45,568 weighted discharges that included a benign cardiac neoplasm. Benign cardiac neoplasms were more often observed in women (64.33%), and the average age was 63.8 years. The most common cardiovascular co-occurrences in patients with benign cardiac neoplasm were atrial tachyarrhythmias (28.93%), heart failure (19.61%), and embolic events such as stroke, myocardial infarct, or pulmonary embolism (19.82%). Other co-occurrences included pulmonary hypertension (7.55%), ventricular arrhythmias (3.23%), and other EKG abnormalities (3.70%). Procedures were numerous in patients with benign cardiac neoplasms. 43% of patients with this diagnosis had some form of cardiac surgery during their hospitalization. Overall, this study found low incidence of benign cardiac neoplasms in the USA during this 13-year study period. However, in the presence of benign cardiac neoplasms, our study showed that cardiovascular co-occurrences are not uncommon and may help to illuminate this otherwise rare diagnosis.

Characteristics, management, and outcomes among admissions for primary cardiac tumors: Results from the National Inpatient Sample.

INTRODUCTION: Primary cardiac tumors (PCT) are rare, and their contemporary outcomes are not well characterized in the literature. We assessed temporal trends in patient characteristics and management of admissions for PCT in US hospitals. METHODS: Admissions with the principal diagnoses of a PCT (benign neoplasm of heart: ICD-9 212.7, ICD-10 D15.1; malignant neoplasm of heart: ICD-9 164.1, ICD-10 C38.0) between 2006 and 2017 were extracted from the National Inpatient Sample. Trends in demographics and clinical profiles were evaluated. We conducted descriptive analyses on the cohort and compared outcomes between those managed medically and surgically. RESULTS: Between 2006 and 2017, 19,111 admissions had the primary diagnosis of a PCT. Of these, 91.1% were benign. Admissions were mostly female (65.0%), caucasian (72.0%), and aged more than 50 years (76.0%). The annual admission rate for PCT was similar from 2006 to 2017 (p trend > .05) and associated with congestive heart failure, diabetes, renal failure, and valvular lesions. PCTs were managed surgically in 12,811 (67.0%) of overall cases, 70.8% for benign and 28.3% for malignant tumors. Overall, the in-hospital mortality rate was 2.3%. Medically managed cases reported a 2.5% higher mortality (p < .001) than those surgically managed. Admissions with malignant tumors were more likely to expire during hospitalization than those with benign tumors (odds ratio, 9.75; 95% confidence interval 6.34-14.99; p < .001). CONCLUSION: Admissions for primary cardiac tumors were primarily women or in their fifth or sixth decade of life. Surgical intervention is more commonly practiced and is associated with better in-hospital survival.

Incidence, prognostic significance, and survival outcomes of primary cardiac sarcoma: An updated population-based retrospective study.

OBJECTIVE: Primary cardiac sarcoma, a rare tumor with an aggressive course and imprecise prognosis, constitutes over 95% of all malignant cardiac tumors. Given the sparsely available evidence, there is a paucity of information regarding current knowledge on cardiac sarcoma. This study aimed to determine the incidence and incidence-based rates, patient characteristics, treatment modalities, and survival factors of cardiac sarcoma. METHODS: A retrospective analysis of the incidence, incidence-based mortality rates and characteristics of cardiac sarcoma between 1975 and 2016 was carried out using the Surveillance, Epidemiology, and End Results (SEER) database. The National Cancer Institute's Joinpoint Regression program was used to calculate the Annual Percentage Changes (APC). Univariate and multivariate regression analysis were used to determine the survival characteristics. RESULTS: A total 408 patients were identified for the incidence analysis, while 385 eligible patients were identified for the survival analysis. The mean age at diagnosis was 46.3±17.9 years. The incidence rate (per 100.000 per year) of cardiac sarcoma within the indicated years was 0.22, with an increased APC of 1.7 (p=0.013, 95% CI=0.5-2.9). A total of 251 (61.5%) patients underwent surgery, 93 (22.8%) patients received adjuvant radiotherapy, and 197 (50.2%) patients received chemotherapy. Surgical resection, chemotherapy, stage of tumor, and younger age significantly improved the survival outcomes (p<0.001). CONCLUSION: Cardiac sarcoma is a rare type of soft tissue sarcomas with poor prognosis. Over the past 30 years, the incidence of cardiac sar-coma has been on the increase. Surgery remains the mainstay of management. Further studies are needed to compare different diagnostic and treatment modalities so as to ascertain the best treatment option that would enhance survival and prognosis of cardiac sarcoma.
