P2.01-065 - Clinico-Radiological and Pathological Evaluation of Lung Adenocarcinoma with Infiltration on the Computed Tomography of the Chest (ID 8877)
09:00 - 09:00 | Presenting Author(s): Asuka Okada
- Abstract
Background:
Invasive mucinous adenocarcinoma of the lung which is well known as poor prognosis is often difficult to distinguish from pneumonia on the chest Computed Tomography (CT). However, the characteristics of lung adenocarcinoma resemble to pneumonia on the chest CT are not known well.
Method:
We retrospectively reviewed 607 patients with lung cancer pathologically diagnosed with adenocarcinoma in Saiseikai Suita Hospital from April 2007 to March 2017.
Result:
Of the 607 patients, 9 cases showed infiltration like pneumonia without any masses or nodules on the chest CT. The patients included 3 males and 6 females, mean age of 69.89 years (range 32-82 years). Many cases relatively needed time from the point of first contact to the medical institution to diagnosis: the average was 142.9 days (range 8-385 days). Furthermore, some of the cases were treated as pneumonia at first. Most of the cases diagnosed with invasive mucinous adenocarcinoma pathologically, but there were 2 cases presenting no or few mucin. These 2 cases also have EGFR major mutation. One patient died within 2 months after diagnosis, but more than half of the cases were confirmed the existence over one year.
Conclusion:
It is important to take lung adenocarcinoma into consideration when we see infiltration on the chest CT scan. We suppose early diagnosis and treatment could lead to relatively good survival.
