Background:
Watch and wait(W & W)for rectal cancer after chemoradiotherapy(CRT)is attracting attention.
Purpose:
To examine regimens and indications from the results of follow-up of cases undergoing W & W in our department.
Materials And Methods:
CRT(SOX therapy 2-5 cycles, 45 Gy)was performed on patients with lower rectal cancer over a period of 2016 to 2020, and 7 patients with clinical complete response(cCR)were followed up.
Results:
With a median follow-up of 33 months(10-74), 4 of 7 patients(57.1%)remained in cCR. Two patients had local relapse more than a year after the start of treatment, were able to undergo salvage surgery, and are alive after surgery. Patients with lateral lymph node metastasis before CRT had para-aortic lymph node metastasis at 8 months.
Conclusions:
Patients with maintained cCR were those with localized, node-negative disease. On the other hand, in patients with lymph node metastasis, including lateral metastasis, it was not possible to perform salvage surgery due to distant metastasis. Careful case selection and follow-up are necessary in the future.
