Clinico-pathological differences between adenocarcinoma in the right and left colo-rectum play a role in determining the prognosis and response to treatment. Studies suggest that primary tumor location is more relevant as the disease progresses and reflects a possible difference in biology and response to therapy. This review aims to explore the clinico-pathological features of right and left colo-rectum and the impact of primary tumor location on prognosis of CRC as well as discuss the available clinical data on tumor sidedness in metastatic colorectal cancer. In so far as the clinical data of tumor sidedness is concerned, very few reviews have discussed the clinical implications of sidedness in heavily pre-treated metastatic colorectal cancer (second and subsequent lines of therapy in metastatic disease). This review aims to fill the current gap in this setting.
左右侧结直肠癌的临床病理差异在决定预后和治疗反应方面发挥着作用。研究表明,随着疾病进展,原发肿瘤位置更为重要,且反映出生物学特性及对治疗反应方面可能存在的差异。本综述旨在探讨左右侧结直肠癌的临床病理特征、原发肿瘤位置对结直肠癌预后的影响,并讨论转移性结直肠癌中肿瘤部位的现有临床数据。就肿瘤部位的临床数据而言,很少有综述讨论过在接受过大量预处理的转移性结直肠癌(转移性疾病的二线及后续治疗)中部位的临床意义。本综述旨在填补这一领域目前的空白。
