A Case Report of Unrespectable Liver Metastases from Cancer Rectosigmoid Colon with Survival Greater Than 6 Years and Clinical Benefit after Multidisciplinary Treatment

Introduction Colorectal cancer represents 1,271 new cases per year in Morocco, However, over the last 30 years we have witnessed a significant increase in the overall survival of metastatic patients due to the arrival of new molecules.  Case Presentation We report the case of a 51 years old african female patient diagnosed for a moderately differentiated adenocarcinoma of the rectosigmoid junction MSS, wild RAS/BRAF, treated with colorectal protection and lymph node dissection, followed by 6 cycles of fulfol- cisplatin as an adjuvant. the follow up revealed the appearance of hepatic masses. The liver biopsy was performed showing a secondary localization of an adenocarcinoma of digestive origin. The patient received four lines of the chemotherapy, anti-EGFR antibodies and immunotherapy following the guidelines. However, since no KRAS NRAS BRAF mutation was detected at the DNA level circulating tumor, no rechallenging of the anti- EGFR was possible. The hepatic progression continued with appearance of pulmonary lesions, the decision was made for a palliative care.  Conclusion Our case highlights that due to the emergence of new effective molecules currently available, associated with a dedicated onco-surgical approach, more patients will be able to benefit from prolonged survival that did not seem achievable at the time of diagnosis.
