Is Circumferential Assessment of Colonic Carcinoma by Computed Tomography Scan and Colonography enough to Predict the Staging?
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2018, Vol 5, Issue 10
Abstract
Background: The modern treatment of rectal cancer relies on correct diagnosis which is a multidisciplinary approach by medical oncologists, radiation therapists, endoscopists, radiologists, and surgeons. Based on their diagnosis treatment varies from curative versus palliative; radical versus local excision, pre-operative chemoradiation therapy, and postsurgical adjuvant therapy. Aim of the Study: This study aims to know the role of computed tomography (CT) scan and colonography in assessing the circumferential involvement of colonic carcinoma required for differentiating the stages of colonic carcinoma. Materials and Methods: A total of 41 patients with colonic carcinoma were investigated with CT scan and colonoscopy to assess the circumferential involvement of the tumor to stage the disease. The final pathological and surgical staging was used as a reference to determine the accuracy of the investigating tools. Observations and Results: Among the 41 patients, 32 (78.04%) were males and 08 (19.51%) were females. Patients aged 40–50 were 09 (21.95%), aged between 50 and 60 were 19 (46.34%), and aged between 60 and 70 were 13 (31.70%). The mean age was 56.34 ± 3.10. The laboratory investigations of serum carcinoembryonic antigen showed <3.5 ng/mL in 03 (%), 3.5–7.0 ng/mL in 11 (26.82%), 7.0–10 ng/mL in 17 (41.46%), and >10.0 ng/mL in 10 (24.39%) patients. Colonoscopy showed T1 lesions in 3 (7.31%), T2 lesions in 09 (21.95%), T3 lesions in 14 (34.14%), and T4 lesion in 05 (12.19%) patients. Conclusions: This study showed colonoscopy and CT colonography together have an overall sensitivity of 92.68%, thus has an important role in the diagnosis of colonic carcinoma. Especially, the accuracy helps in staging of T2 and T3 tumors facilitating the choice of treatment.
