The image characteristic and the value of CT-Scanner in diagnosis of non-small cell lung cancer and follow-up post chemotherapy

SUMMARY

Lung cancer is non-small cell type common , accounting for 80% of all lung cancers and is the kind of good response to chemotherapy. The problem of early diagnosis and follow-up after treatment chemicals tumors is essential.

Objective: Describe some features computerized tomography images of lung cancer non-small cell and rating the value of computerized tomography in monitoring chemotherapy lung cancer non -small cell.

Subjects and Methods: The study conducted on 47 patients diagnosed with lung cancer non -small cell had computed tomography movie multiple slices at Medical University Hospital from 5/2012 to Hanoi in May / 201. Study design: descriptive cross-sectional, prospective combined with retrospective.

Results: In 47 patients with 28 patients with tumors in the (R) 59.6%, 19 patients with tumors in the (L) 40,46%. Smallest tumor size 2,4cm, the largest 8.2 cm, medium 5.3 cm. Before average injection of contrast 100% of tumors with low levels < 50 Hu, after injecting drug absorbed 100% u > 20 HU. Bo irregular tumor (lobe segments) or fringed or hemp (100%). In 38 patients with metastases that 100% cost- compartment shaft size > = 15 mm and soaked after dye injection drugs. Which necrotic nodes, adhesive 9 patients (23.7%), Lymphadenopathy mere 29 patients (76.3%). Results after 6 round treatment chemicals according to RECIST Version 1.1: Complete response of 25 patients (53.3%), can meet 17 patients (36.1%), Stable 5 patients (10.6%), Progress: 0 patients (0%)

Conclusion: CLVT valuable in the diagnosis and monitoring of cancer chemotherapy -small cell lung.
