CQ29. Is Chemotherapy Effective for Advanced or Relapsed Medullary Carcinoma?
We studied the literature for the effectiveness of chemotherapy on advanced or relapsed medullary thyroid carcinoma with no indications for surgery, where tangible tumors were detectable on palpation or imaging studies. Serum cacitonin level and CEA level are sensitive tumor markers of medullary carcinoma and these elevations are often initial signs of recurrence before findings on imaging studies, but no reports are available for chemotherapy for cases without relapsed tumors for which sizes can be measured.
