Prognostic Implication of the Lymphangitic Carcinomatosis Pattern on Perfusion Lung Scan

Abstract

A lymphangitic carcinomatosis perfusion pattern on scintigraphic imaging is associated with a poor prognosis. Nuclear medicine physicians should be aware of this association and that raising the suspicion for a metastatic process may make a difference in the treatment plan of these patients.

The added value of quantitative 18F-FDG-PET/CT parameters in the assessment of pulmonary lymphangitic carcinomatosis in lung cancer

“…Despite these limitations, the findings of Jreige et al have potential in improving the accurate identification of lymphangitic carcinomatosis, which has the treatment and prognostic implications. Lymphangitic carcinomatosis is associated with worse prognosis in various extrapulmonary malignancies (15)(16)(17). The prognostic impact of lymphangitic carcinomatosis in the setting of primary lung malignancies, however, is less clear.…”
