Risk calculators and risk factors for Pericarditis in malignancy

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor-In-Chief: Varun Kumar, M.B.B.S.; Lakshmi Gopalakrishnan, M.B.B.S.

Overview

Many malignant neoplasms such as lung cancer, breast cancer, esophageal cancer, lymphomas, melanomas, kaposi's sarcoma and leukemias may metastasize to pericardium causing pericarditis, effusion, cardiac tamponade and pericardial constriction. Malignant pericardial effusion is seen in approximately 50-60% of patients presenting with pericardial effusion who have history of malignancy[1][2]. Among patients presenting with pericarditis or pericardial effusion with no history of malignancy, undiagnosed underlying malignancy was detected in 4-7%[3][4][5].

Malignancy related pericardial disease can manifest as pericarditis, pericardial effusion, cardiac tamponade or pericardial constriction.

Epidemiology and demographics

In developed countries malignancy is the leading cause of cardiac tamponade secondary to pericardial effusion. Malignant pericardial effusion is seen in approximately 50-60% of patients presenting with pericardial effusion who have history of malignancy[1][2]. Among patients presenting with pericarditis or pericardial effusion with no history of malignancy, undiagnosed underlying malignancy was detected in 4-7%[3][4][5].

Carcinoma of the lung is the most common cause for pericardial effusion in malignancy accounting for approximately 40%. Another 40% of cases could be due to breast carcinoma and lymphomas. Carcinoma of GI tract, melanoma, sarcomas, and other neoplastic diseases are less common.

Kaposi sarcoma and lymphomas associated with HIV were other neoplastic causes of pericardial effusion which accounted for 5% and 7% respectively[6] in one study and 15% together[7] in another series. However, with the use of antiretroviral agents, the incidence of Kaposi carcinoma and subsequent pericardial effusion has considerably decreased.

In regions where tuberculosis is not highly prevalent, malignancy may be the most common cause of a hemorrhagic effusion[8][9]

Sex

Higher incidence of the pericardial effusion related to malignancy is observed among males with ratio of 7:3 as reported in a series[10]

Natural history, prognosis and complications

Gaurded prognosis associated with malignancies is worsened by pericardial effusion and cardiac tamponade. Children may have poor prognosis and thus, prompt detection and treatment of cardiac tamponade improves survival[11][12].

Patients rarely present with cardiac tamponade as their first presentation. Superior vena cava syndrome may occur in few secondary to either coexisting tumor or rapid accumulation of pericardial effusion[13].

Prognosis of symptomatic malignant pericardial disease is grave with a short life expectancy of 2-4 months[14][15][16][17]. While the patients with hematologic[18] or breast cancer[19], or those in whom malignant cells are not present in pericardium[20] have better prognosis in comparison to those with solid tumors, lung cancer[21], etc.

Pathophysiology

Pericardium may be involved by direct local spread from neoplasms such as breast and lung carcinomas or by metastatic spread via blood stream and lymphatics as in melanomas, lymphomas and leukemias.

Pericardial effusion in such situations may occur either secondary to pericardial inflammation or obstruction of lymphatic drainage by enlarged mediastinal nodes[22][11][5].

  13. Malignant pericardial teratoma
  14. Rhabdomyosarcoma with tuberous sclerosis
  15. Pheochromocytoma
  16. Neuroblastoma
  17. Ganglioneuroblastoma
  18. Leiomyosarcomas
  19. Liposarcomas
  20. High-grade sarcomas
  21. Burkitt lymphoma
  22. Kaposi sarcoma and primary cardiac lymphoma in association with human immunodeficiency virus (HIV) infection
  23. Intrapericardial teratoma in the fetus and neonate

Diagnosis

History and symptoms

In addition to malignancy specific presentation, patients may present with the following symptoms due to pericardial involvement:

Many patients may be asymptomatic and pericardial involvement may be detected incidentally on chest x-ray or on autopsy.

Physical examination

Cachexia, weight loss and other organ-system specific abnormalities secondary to malignancy.

Vitals: Tachycardia, pulsus paradoxus and hypotension(in cardiac tamponade)

Neck: Jugular venous distension with a prominent Y descent and Kussmaul's sign

Chest: Pericardial knock, pericardial rub and distant heart sounds

Abdomen: Hepatomegaly, ascites

Extremities: Ankle edema
