Background:
Newly or already diagnosed cancer might significantly influence the clinical presentation, outcome, and therapy of acute pulmonary embolism (PE).
Methods:
Out of 1745 patients with acute PE, 66 patients were diagnosed with cancer during an initial hospitalization due to acute PE (where PE was the first clinical manifestation of cancer), 165 patients had known cancer treated in the last 6 months, and 1514 patients had acute PE without known or suspected cancer. The primary end-point of the present study was all-cause hospital death. The secondary end-points were the proportion of patients treated with thrombolysis and who had severe disease, and the ocurrence of major or clinically relevant nonmajor bleeding.
Results:
Patients with PE as the first presentation of cancer had the highest hospital mortality rate compared to the other two groups (HR for the mortality rate in patients without cancer as a reference, adjusted to four-stratum mortality risk, and Charlson's comorbidity index was 3.440; 95% confidence interval (CI), 1.795-6.591; p < 0.001). Patients with known cancer before PE had a significantly lower chance of being treated with thrombolysis than patients without cancer (OR, 0.523; 95% CI, 0.339-0.807; p = 0.003); additionally, this difference was attenuated but remained when the OR was adjusted to age (OR, 0.542; 95% CI, 0.351-0.838; p = 0.006). Patients with known cancer had a higher frequency of high-risk PE compared with patients without cancer (18.2% vs. 12.8%; p < 0.001). Patients with PE as the first manifestation of cancer had a higher frequency of intermediate-high-risk PE than those without (36.4% vs. 30.9%; p < 0.001). There was no significant difference in bleeding during hospitalization between groups.
Conclusion:
Patients with cancer had a more severe presentation of acute PE than patients without. Furthermore, patients with PE as the first manifestation of cancer had the highest hospital mortality rate, and patients with known cancer were least likely to be treated with thrombolysis.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
