TOPLINE:
METHODOLOGY:
- The combination of neoadjuvant chemoradiotherapy, total mesorectal excision, and postoperative adjuvant chemotherapy is the current standard of care for locally advanced rectal cancer. But with pathological complete response rates of only 10%-15% and more than 30% of patients developing distant metastases within 3 years, outcomes remain suboptimal.
- Chinese investigators took a step to improve the situation, applying TACE — a standard treatment for colorectal liver metastases — to rectal tumors, dubbing the approach transcatheter rectal arterial chemoembolization (TRACE).
- As in TACE, TRACE uses precisely injected chemotherapeutic and vaso-occlusive agents to shut down blood flow to tumors, starving them of oxygen and nutrients.
- The research team tried the approach in 111 patients with stage II or III rectal tumors and performance status scores of 0-1.
- TRACE was delivered with oxaliplatin and followed by radiotherapy and S1 chemotherapy (tegafur, gimeracil, and potassium oteracil). Total mesorectal excisions were performed 4-8 weeks later, followed by mFOLFOX6 (5-fluorouracil, leucovorin, and oxaliplatin) or CAPOX (oxaliplatin and capecitabine) chemotherapy for 4-6 months.
TAKEAWAY:
- Overall, 20.7% of patients undergoing TRACE had a pathological complete response, and almost half (48.65%) had a major pathological response.
- Nearly 62% of patients were disease-free at 5 years, and almost 75% were alive at 5 years.
- No serious surgical complications occurred, but 21.6% of patients had postoperative complications. Overall, about 26% of patients (29 of 111) had grade 3/4 toxicities.
IN PRACTICE:
“The addition of transcatheter rectal arterial chemoembolisation to the neoadjuvant therapy can improve the pathological remission rate and prognosis in patients with locally advanced rectal cancer, without increasing the incidence of preoperative adverse events and postoperative complications,” the researchers concluded. “Given its promising effectiveness and safe profile, incorporating TRACE into the standard treatment strategy for patients with [locally advanced rectal cancer] should be considered.”

The work, led by W. Yang of the Army Medical University in Chongqing, China, was published in Clinical Oncology.
LIMITATIONS:
The study was performed at a single center with no control arm in a Chinese population.
DISCLOSURES:
The work was funded by the Third Military Medical University in China. The investigators had no conflicts of interest.
