P3.13-017 - Review of Lung Cancers on the Stage and Growth Rate, Matched with Lung RADs Category, in Previously Treated with Breast Cancer Patients (ID 8941)

- Abstract
Background:
The incidence of lung cancer is dramatically increased. To review the clinical and imaging pattern of lung cancer, diagnosed and treated with breast cancer within 15 years. To evaluate clinical/pathologic stages, doubling time, and lung RADs categories, related with hormone receptor of breast cancers.
Method:
Retrospectively reviewed medical record of breast cancer patients, since 2007. 17 female patients(19 breast cancers)were included. 19 lung lesions were detected. Age range was from 43 to 78 years old(mean 63.8). We reviewed TNM stage, lung RADS, tumor doubling time and the status of hormone receptor. One patient had bilateral breast cancers, mucinous carcinoma (left), and invasive ductal carcinoma(right). Two nodules were shown, invasive ductal carcinoma and one is DCIS.
Result:
The pathology of breast cancer was invasive ductal carcinoma(15), DCIS(2) mucinous ca(1), papillary ca(1). The T stage of breast cancers was T1(17), T2(2) . The subtype of lung cancers was adenocarcinoma, mostly. T stage of lung cancer is T1(16), one is AIS, T3(1), T4(2). The node metastases were not shown and 2/17 showed distant metastases. The primary tumor dimension was from 8mm to 29 mm. The interval between two tumors from 11 days to 14 years. Lung RADs categories were 4A/B(14), 3(2), 2(3) and final category were increased in 5 (from 2 to 4A or B(4 cases), 3 to 4A/B(2 cases)). In 7 interval growing, the tumor doubling time was from70 to 2016 days (mean 712 days).Figure 1
Conclusion:
The receptor (-) breast cancer were higher T stage of lung cancer and lymph nodes metastases were more common. The growth rate of lung nodules are slow as matched with lung RADS category. Volume doubling time of lung cancers ranging from 70 to 2016 days, and exceptionally short in one of them. RADS up scaling in 7 cases are all T1 stage lung cancers, favorable response for the treatment.
