Purpose No effective therapy is currently available for the management of patients with metastatic medullary thyroid carcinoma (MTC). The efficacy of pretargeted radioimmunotherapy (pRAIT) with bispecific monoclonal antibody (BsMAb) and a iodine-131 (131I) –labeled bivalent hapten is evaluated. Patients and Methods Twenty-nine patients with advanced, progressive MTC, as documented by short serum calcitonin doubling times (Ct DTs), received an anti–carcinoembryonic antigen (CEA)/anti–diethylenetriamine pentaacetic acid (DTPA) –indium BsMAb, followed 4 days later by a 131I-labeled bivalent hapten. Overall survival (OS) was compared with 39 contemporaneous untreated MTC patients with comparable prognostic indicators. Results OS was significantly longer in high-risk, treated patients (Ct DT < 2 years) than in high-risk, untreated patients (median OS, 110 v 61 months; P < .030). Forty-seven percent of patients, defined as biologic responders by a more than 100% increase in CtDT, experienced significantly longer survival than nonresponders (median OS, 159 v 109 months; P < .035) and untreated patients (median OS, 159 v 61 months; P < .010). Treated patients with bone/bone-marrow disease had a longer survival than patients without such involvement (10-year OS, 83% v 14%; P < .023). Toxicity was mainly hematologic and related to bone/bone-marrow tumor spread. Conclusion pRAIT against CEA induced long-term disease stabilization and a significantly longer survival in high-risk patients with Ct DTs less than 2 years, compared with similarly high-risk, untreated patients. Ct DT and bone-marrow involvement appear to be prognostic indicators in MTC patients who undergo pRAIT.

AbstractSerum calcitonin (Ct) and carcinoembryonic antigen (CEA) doubling times (DT) are considered to be strong prognostic markers in patients with medullary thyroid carcinoma (MTC). The Objective of this work is to study the effect of MTC debulking on Ct and CEA DTs. 4 patients with MTC are presented who after an initial neck operation had residual disease were followed-up with serial measurements of serum Ct and CEA for several years before and after a secondary incomplete removal of involved cervical lymph nodes.The patients received no other treatment for MTC. Ct and CEA DTs were determined after fitting the Ct or CEA values to an exponential growth equation.In patient A, Ct DT increased from 1.45 years (1.17–1.89, 95% CI) preoperatively, to 5.72 (3.22–25.77) postoperatively. In patient B, Ct DT was 1.63 years (1.36–2.02) preoperatively, and very long (serum Ct practically ceased increasing) postoperatively. In patient C, Ct DT was 4.03 years (2.22–21.58) before, and very long after the operation. In patient D, Ct DT from 1.16 years (0.82–1.99) before, increased to 4.21 years (3.04–6.86) after the operation. The changes in CEA DTs were similar to those of Ct DTs in 2 patients in whom the tumor was apparently producing the protein.In conclusion, surgical MTC cytoreduction in 4 patients caused an increase in the Ct and CEA DTs, and the patients could be reclassified in new Ct DT-based strata with better prognosis than before the operation. We hypothesize that such tumor burden reduction may slow the growth of any residual MTC and we discuss mechanisms that could be responsible for this phenomenon.

IntroductionThe prognostic value of serum calcitonin (CT) and carcinoembryonic antigen (CEA) doubling time has been recently demonstrated in medullary thyroid carcinoma (MTC) patients. No study has yet validated the surrogate role of these markers for survival during treatment. The aim of this study was to evaluate, in patients with advanced MTC treated with cytotoxic chemotherapy, the relationship between early changes of serum CT or CEA levels and progression-free survival (PFS).Patients and methodsThe files of 28 consecutive metastatic MTC patients with progressive disease, treated with cytotoxic chemotherapy in a single tertiary referral center between 2000 and 2010, were retrospectively reviewed. Serum CT and CEA measurements and radiological Response Evaluation Criteria in Solid Tumors (RECIST) evaluations were collected every 3 months. The relationship between changes in serum CT and CEA levels at 3 months, defined by an increase or a decrease of at least 20%, and PFS according to RECIST 1.0, was estimated using Kaplan–Meier curves and log-rank test.ResultsThe median follow-up for the 28 patients was 68 months. According to RECIST, a partial response, a stabilization or a progression was observed in 14, 43, and 43% of cases respectively. Median PFS from the initiation of cytotoxic chemotherapy was 4.5 months. Median PFS among patients with and without significant CT increase at 3 months was 4.6 and 3.3 months respectively (P=0.75). Median PFS among patients with a significant CEA increase at 3 months was 2.7 months, whereas it was 19.1 months in patients in whom CEA did not increase (P=0.02).ConclusionAt 3 months, an increase of serum CEA but not of CT levels appears as a valuable surrogate marker of short PFS in MTC patients treated with cytotoxic chemotherapy. A prospective validation is expected.

Background and Objectives: Medullary thyroid carcinoma (MTC) accounts for 1–2% of all thyroid malignancies, and it originates from parafollicular “C” cells. Carcinoembryonic antigen (CEA) is a tumor marker, mainly for gastrointestinal malignancies. There are references in literature where elevated CEA levels may be the first finding in MTC. The aim of this study is to determine the importance of measuring preoperative and postoperative CEA values in patients with MTC and to define the clinical significance of the correlation between CEA and the origin of C cells. Materials and Methods: The existing and relevant literature was reviewed by searching for articles and specific keywords in the scientific databases of PubMedCentraland Google Scholar (till December 2020). Results: CEA has found its place, especially at the preoperative level, in the diagnostic approach of MTC. Preoperative CEA values >30 ng/mL indicate extra-thyroid disease, while CEA values >100 ng/mL are associated with lymph node involvement and distant metastases. The increase in CEA values preoperatively is associated with larger size of primary tumor, presence of lymph nodes, distant metastases and a poorer prognosis. The clinical significance of CEA values for the surgeon is the optimal planning of surgical treatment. In the recent literature, C cells seem to originate from the endoderm of the primitive anterior gut at the ultimobranchial bodies’ level. Conclusions: Although CEA is not a specific biomarker of the disease in MTC, itsmeasurement is useful in assessing the progression of the disease. The embryonic origin of C cells could explain the increased CEA values in MTC.

OBJECTIVE: To evaluate the usefulness of preoperative serum calcitonin (sCT) in patients with nodular disease without suspicion of medullary thyroid carcinoma (MTC) in history or cytology. PATIENTS AND METHODS: sCT was measured before thyroidectomy in 494 patients with nodular disease who had no family history of MTC or multiple endocrine neoplasia type 2, and no cytological suspicion of MTC. RESULTS: Basal sCT was < 10 ng/mL in 482 patients and none of them had MTC. One patient with basal sCT > 100 pg/mL had MTC. Among the 11 patients with basal sCT between 10 and 100 pg/mL, MTC was diagnosed in only one. The two patients with MTC were submitted to total thyroidectomy, combined with elective lymph node dissection indicated exclusively based on hypercalcitoninemia, and sCT was undetectable after six months. CONCLUSIONS: Preoperative sCT is useful for the detection of sporadic MTC in patients with nodular disease, even in the absence of suspicious history or cytology.

ObjectiveThe progression of medullary thyroid cancer is difficult to assess with imaging modalities; we studied the interest of calcitonin and carcinoembryonic antigen (CEA) doubling times and of Ki-67 labeling and mitotic index (MI).Patients and methodsFifty-five consecutive medullary thyroid carcinoma (MTC) patients with elevated calcitonin levels underwent repeated imaging studies in order to assess tumor burden and progression status. We looked for relationships between tumor burden and levels of calcitonin and CEA and between progression status according to the response evaluation criteria in solid tumors (RECIST) and calcitonin and CEA doubling times, and Ki-67 labeling and MI.ResultsThe calcitonin and CEA levels were correlated with tumor burden. Ten patients with calcitonin levels below 816 pg/ml had no imaged tumor foci. Among the 45 patients with imaged tumor foci, 19 had stable disease and 26 had progressive disease, according to the RECIST. The calcitonin and CEA doubling times were strongly related to disease progression, with very few overlaps: 94% of patients with doubling times shorter than 25 months had progressive disease and 86% of patients with doubling times longer than 24 months had stable disease. Ki-67 labeling and MI were not significantly associated with disease progression.ConclusionFor MTC patients, the doubling times of both calcitonin and CEA are efficient tools for assessing tumor progression.
