Journal Title: IP Journal of Diagnostic Pathology and Oncology - Year 2018, Vol 3, Issue 1
Abstract
Introduction Lung cancer is the most common cancer in the world and accounts for nearly 13 of all new cancer diagnoses in both sexes combined and currently is the leading cause of cancer related deaths worldwide Due to dismal overall survival all efforts should be made to improve the diagnosis and treatment to lung cancer patients So the aim of this study is to explore the possibility of using fused CTPET images for accuracy of staging and three dimensional radiation treatment planning in regard delineation of target in patients of carcinoma lung NSCLC who are referred to us for radical radiotherapyMaterials and Methods Itrsquos a hospital based prospective study in which 16n cancer patients who had biopsy proven NSCLC and were referred to us for radical radiotherapyResults The mean age was 65 yrs 8125 13 patients are male and 1875 3 are female PETCT imaging changed the staging in 4 patients 25 metastatic disease found in 2 patients 125 The registration of fused images of PET with planning CT scan decreased the gross tumor volume GTV in 10 patients 7142 decreased volume in 4 patients 2858 The 3DCRT planes were modified in 5patients 35Conclusion Our findings extend the conclusion of observational studies in which FDGPET has already been used to improve cancer staging and the definition of GTV for radiation treatment planning It showed 25 change in staging 12 detecting distant metastasis and 35 alteration in radiotherapy treatment plan PETCT should be routinely used for staging and if feasible it should be incorporated in radiotherapy treatment planningKeywords NSCLC PETCT 3DCRT
