Abstract
BACKGROUND

Liver metastasis is the most common form of distant metastasis in colorectal cancer, and the only possible curative treatment for patients with colorectal liver metastases (CRLM) is hepatectomy. However, approximately 25% of patients with CRLM have indications for liver resection at the initial diagnosis. Strategies aimed at downstaging large or multifocal tumors to enable curative resection are appealing.

CASE SUMMARY

A 42-year-old man was diagnosed with ascending colon cancer and liver metastases. Due to the huge lesion size and compression of the right portal vein, the liver metastases were initially diagnosed as unresectable lesions. The patient was treated with preoperative transcatheter arterial chemoembolization (TACE) consisting of 5-fluorouracil/Leucovorin/oxaliplatin/Endostar®. After four courses, radical right-sided colectomy and ileum transverse colon anastomosis were performed. Postoperatively, the pathological analysis revealed moderately differentiated adenocarcinoma with necrosis and negative margins. Thereafter, S7/S8 partial hepatectomy was performed after two courses of neoadjuvant chemotherapy. Pathological examination of the resected specimen revealed a pathologically complete response (pCR). Intrahepatic recurrence was detected more than two months after the operation, and the patient was then treated with TACE consisting of irinotecan/Leucovorin/fluorouracil therapy plus Endostar®. Subsequently, the patient was treated with a γ-knife to enhance local control. Notably, a pCR was reached, and the patient's overall survival time was > 9 years.

CONCLUSION

Multidisciplinary treatment can promote the conversion of initially unresectable colorectal liver metastasis and facilitate complete pathological remission of liver lesions.

Core Tip: We report a multidisciplinary strategy, including 5-fluorouracil/Leucovorin/oxaliplatin/Endostar® (mFOLFOX6 plus Endostar®) and transcatheter arterial chemoembolization, that may help improve resectability of initially unresectable colorectal liver metastasis (CRLM) and achieve pathologically complete response (pCR). After the recurrence of liver metastasis, the patient received TACE comprising irinotecan/Leucovorin/fluorouracil therapy plus Endostar® and was treated with γ-knife. The patient's overall survival time exceeded 9 years. To date, this is the first case that mFOLFOX6 combined with Endostar® in conversion therapy of initially unresectable CRLM and liver metastases that achieved pCR. Our study implies that Endostar® has a potential value in conversion therapy and combination therapy of initially unresectable CRLM.
