Histological Alterations, Diagnosis and Therapeutic Approaches of Colorectal Cancer: A Review Article

Colorectal cancer (CRC) is one of the most common cancers and a major public health burden leading to cancer-related morbidity and mortality throughout the world. Its induction is a multistaged process which includes genetic and epigenetic mutations, and complicated environmental/lifestyle interactions. Histologically, CRC is mainly adenocarcinoma that develops from dysplastic transformation of the colonic epithelium and has known variants which affect prognosis and response to treatment. The cumulative effect of architectural distortion, cellular irregularities, invasive extension beyond muscularis mucosae and through the surrounding lymphovascular channels to form metastases describes disease progression. Early diagnosis is paramount for survival. Diagnostic work up includes screening tools, including fecal occult blood test and colonoscopy, followed by histo-pathological diagnosis and radiologic staging. Molecular diagnostics for mutation analysis and microsatellite instabilty status have provided additional clarification to categorization and treatment strategy in recent years. Therapies for CRC are dependent on the stage, as local disease is resected surgically and treatment there-after administered. The introduction of adjuvant and neo-adjuvant systemic chemotherapy, radiotherapy (especially for rectal cancer), new targeted biologic agents, and as of late immune therapy have transformed the management of both metastatic and locally advanced disease. Identification of target therapy according to the molecular tumor profile is essential to patients who respond to this treatment. In conclusion, the histopathological features of CRC and early diagnosis options and modern therapeutic opportunities should be combined to best control colorectal cancer as well as additional new research approaches in response to worldwide diseases.
