4. Conclusion
Our case has demonstrated the effectiveness of readministering cetuximab
as a salvage chemotherapeutic agent after administering nivolumab to a
patient diagnosed as having a progressive disease for the recurrence of
cervical lymph node metastasis after tongue cancer surgery. Our findings
suggest that the immunostimulatory effect of nivolumab and reactivation
of cetuximab enhance the antitumor effect of the therapy and highlight
the need to accumulate more cases similar to ours to further validate
the data.
