P3.13-038a - Metastases in T1-T2 classed Lung Cancer (ID 7339)
09:30 - 09:30 | Author(s): R. Ouji
- Abstract
Background:
Lung cancer is the first cancer responsible for metastases. They can be either intra-or extra-thoracic. Their diagnosis when the cancer is locally non-advanced modifies completely the treatment. The aim of this work is to find out variables influencing metastases occurrence in T1-T2 classed lung cancer.
Method:
Retrospective review of data of 63 patients (60 males and 3 females) with confirmed lung cancer, which were classed T1 or T2 according to the TNM 7 in the work up of their disease and who were explored in the imaging department of our institution between January 2011 and December 2016. Patients were subdivided into two groups: with or without metastases. The variables tested to find out a relationship with metastases occurrence were age, T1 or T2 status, N status and histological type of the cancer. A significant statistical relationship was retained when p was ≤0.05.
Result:
The mean age of the included patients was 61 years (ranging between 43 and 73 years). Adenocarcinoma was the most common histological type (71%). Twenty seven patients (43%) had metastases; 21 of them (77%) had extra-thoracic ones. Comparing patients with and without metastases, no significant relationship was found between the T1 or T2 stage (p= 0.147), the age (p=0.745) and metastases occurrence. In the opposite, they were statistically related to N2-N3 lymph nodes stage (p=0.032) and to adenocarcinoma (p=0.006).
Conclusion:
Metastases are quite frequent in T1-T2 classed lung cancer. Their occurrence was related to the N stage and to the adenocarcinoma.
