Para-Aortic Lymphadenectomy and Subsequent Chemotherapy after Resection of the Primary Lesion for Poorly Differentiated Adenocarcinoma of the Sigmoid Colon - A Case Report



Para-Aortic Lymphadenectomy and Subsequent Chemotherapy after Resection of the Primary Lesion for Poorly Differentiated Adenocarcinoma of the Sigmoid Colon - A Case Report



Gan to Kagaku Ryoho. Cancer and ChemoTherapy 42(11): 1435-1437



The patient was a 68-year-old male who had bloody stools. A colonoscopy revealed a sigmoid colon stricture, and a histological examination confirmed the presence of a poorly differentiated adenocarcinoma.Computed tomography revealed the involvement of a para-aortic lymph nodes, without other metastatic lesions. The patient underwent a sigmoidectomy (with regional lymph node dissection) and a para-aortic lymph node biopsy to prove the histological conformation. Subsequently, he was provided with 6 courses of modified FOLFOX6(mFOLFOX6) chemotherapy, resulting in a marked decrease in para-aortic lymph node involvement. He subsequently underwent a para-aortic lymphadenectomy. The resected specimen was mostly composed of fibrous degenerative tissue; viable cancer cells were observed only in a 2-mm² area. The patient was provided with 6 more courses of mFOLFOX6 chemotherapy, and has since been free of recurrence (for 6 years and 1 month after the second surgery).
