Multifocality increases the risk of recurrence in patients with papillary thyroid carcinoma (PTC); however, it is unclear whether multifocality justifies more extensive or aggressive surgical treatment. Here, we evaluated the effect of the operative extent on the recurrence-free survival (RFS) of patients with multifocal PTC. Between 2010 and 2019, 718 patients with unilateral multifocal PTC were enrolled; 115 patients (16.0%) underwent ipsilateral thyroid lobectomy, and 606 patients (84.0%) underwent total thyroidectomy. With a mean follow up of 5.2 years, RFS was comparable between the total thyroidectomy and lobectomy groups (p = 0.647) after adjusting for potential confounders. Multivariable Cox regression analysis also demonstrated that the operative extent was not an independent predictor of recurrence (HR 1.686, 95% CI: 0.321–8.852). Subgroup analyses further indicated that both total thyroidectomy and thyroid lobectomy resulted in comparable RFS for multifocal PTC patients with other high-risk factors, including tumor size > 1 cm (p = 0.711), lymph node metastasis (p = 0.536), and intermediate ATA risk of recurrence (p = 0.682). In conclusion, thyroid lobectomy was not associated with the risk of recurrence in patients with multifocal PTCs. Multifocality in PTC may not always require aggressive surgery.

Abstract Background To investigate the association between postoperative lymph nodes (LNs) recurrence and distinct serum thyroglobulin (Tg) levels in patients with papillary thyroid carcinoma (PTC). Methods This study included PTC patients who underwent total thyroidectomy (TT) with at least central neck dissection and then re-operated due to recurrence of LNs between January 2013 and June 2018. These patients were grouped by negative or positive serum Tg levels according to the American Thyroid Association guidelines. Results Of the 60 included patients, 49 underwent radioactive iodine (RAI) treatment. Maximum unstimulated Tg (uTg) ≥ 0.2 ng/mL were associated with larger diameter of recurrent LNs (P = 0.027), and higher rate of metastatic LNs (P < 0.001). Serum-stimulated Tg (off-Tg) ≥ 1 ng/mL (P = 0.047) and unstimulated Tg (on-Tg) ≥ 0.2 ng/Ml (P = 0.013) were associated with larger diameter of recurrent LNs. Number of metastatic LNs ≥ 8 was an independent predictor for postoperative maximum uTg ≥ 0.2 ng/mL (OR = 8.767; 95% CI = 1.392–55.216; P = 0.021). Ratio of metastatic LNs ≥ 25% was an independent predictor for off-Tg ≥ 1 ng/mL (OR = 20.997; 95% CI = 1.649–267.384; P = 0.019). Conclusion Postoperative Tg-positive status was associated with larger size of recurrent LNs. Number of metastatic LNs ≥ 8 and ratio of metastatic LNs ≥ 25% were independent predicators for uTg-positive and off-Tg-positive status, respectively.

There is no consensus regarding the timing of adjuvant radioactive iodine therapy (RAI) therapy in low- and intermediate-risk papillary thyroid carcinoma (PTC). We analyzed the impact of adjuvant RAI on overall survival (OS) in low- and intermediate-risk PTC. The National Cancer Data Base was queried from 2004 to 2011 for pN0M0 PTC patients having near/subtotal or total thyroidectomy and adjuvant RAI. Tumors ≤1 cm with negative margins were low risk while 1.1- to 4-cm tumors with negative margins or ≤1 cm with microscopic margins were termed intermediate risk. RAI in ≤3 months and between 3 and 12 months was termed as early and delayed, respectively. Survival analysis was performed after adjusting for patient and tumor-related variables. There were 7,306 low-risk and 16,609 intermediate-risk patients. Seventeen per cent low-risk and 15 per cent intermediate-risk patients had delayed RAI. Kaplan-Meier analysis did not show a difference in OS for early versus delayed RAI administration in low- (10-year OS 94.5% vs 94%, P = 0.627) or intermediate-risk (10-year OS 95.3% vs 95.9%, P = 0.944) patients. In adjusted survival analysis, RAI timing did not affect OS in all patients (hazard ratios = 0.98, 95% confidence interval = 0.71–1.34, P = 0.887). In conclusion, the timing of postthyroidectomy adjuvant RAI therapy does not affect OS in low- or intermediate-risk PTC.

Abstract Purpose To investigate serum thyroglobulin (Tg) levels in papillary thyroid carcinoma (PTC) patients with lymph nodes (LNs) recurrence, thereby evaluating possible risk factors and structural features of LNs recurrence. Methods All the patients with primary PTC who underwent total thyroidectomy (TT) with central or lateral neck dissection and then re-operated due to LNs recurrence between January 2013 and June 2018 were included. Patients were subdivided groups by different Tg levels. Results This study included 60 patients with LNs recurrence. Of all, 49 patients underwent radioactive iodine (RAI) treatment. Maximum unstimulated Tg (uTg) ≥ 0.2 ng/mL were associated with larger diameter of recurrent LNs (P = 0.027), higher possibility of diameters of recurrent LNs ≥ 25 mm (P = 0.023) and higher ratio of metastatic LNs (P < 0.001). Pre-RAI ablation serum-stimulated Tg (off-Tg) ≥ 1 ng/mL and unstimulated Tg detected at 1 week after RAI ablation (on-Tg) ≥ 0.2 ng/mL were associated with larger diameter of recurrent LNs and higher possibility of diameters of recurrent LNs ≥ 25 mm. Number of metastatic LNs ≥ 8 was an independent predictor for maximum uTg ≥ 0.2 ng/mL (OR = 8.767; 95% CI = 1.392–55.216; P = 0.021). Ratio of metastatic LNs ≥ 25% was an independent predictor for off-Tg ≥ 1 ng/mL (OR = 20.997; 95% CI = 1.649-267.384; P = 0.019). Conclusion Tg-positive was associated with larger size of recurrent LNs. Number of metastatic LNs ≥ 8 could independently predict maximum uTg-positive. Ratio of metastatic LNs ≥ 25% was an independent predicator for off-Tg-positive.

ContextFollowing total thyroidectomy and radioactive iodine (RAI) ablation, serum thyroglobulin levels should be undetectable to assure that patients are excellent responders and at very low risk of recurrence.ObjectiveTo assess the utility of stimulated (sTg) and non-stimulated (nsTg) thyroglobulin levels in prediction of patients outcomes with differentiated thyroid cancer (DTC) following total thyroidectomy and RAI ablation.MethodA prospective observational study conducted at a University Hospital in Saudi Arabia. Patients diagnosed with differentiated thyroid cancer and were post total thyroidectomy and RAI ablation. Thyroglobulin levels (nsTg and sTg) were estimated 3–6 months post-RAI. Patients with nsTg &lt;2 ng/ml were stratified based on their levels and were followed-up for 5 years and clinical responses were measured.ResultsOf 196 patients, nsTg levels were &lt;0.1 ng/ml in 122 (62%) patients and 0.1–2.0 ng/ml in 74 (38%). Of 122 patients with nsTg &lt;0.1 ng/ml, 120 (98%) had sTg levels &lt;1 ng/ml, with no structural or functional disease. sTg levels &gt;1 occurred in 26 (35%) of patients with nsTg 0.1–2.0 ng/ml, 11 (15%) had structural incomplete response. None of the patients with sTg levels &lt;1 ng/ml developed structural or functional disease over the follow-up period.ConclusionSuppressed thyroglobulin (nsTg &lt; 0.1 ng/ml) indicates a very low risk of recurrence that does not require stimulation. Stimulated thyroglobulin is beneficial with nsTg 0.1–2 ng/ml for re-classifying patients and estimating their risk for incomplete responses over a 7 years follow-up period.

The objective of this study was to describe the rare thyroid MALT lymphoma concomitant with papillary thyroid carcinoma in a male patient who was submitted to total thyroidectomy. Treatment and follow-up issues are addressed. Male patient complains of fast thyroid enlargement without lymphadenophaty and normal clinical exams. Total thyroidectomy was indicated and performed without any complications. The pathology showed multicentric papillary thyroid carcinoma, concomitant thyroid MALT lymphoma and Hashimoto's thyroiditis. The immunohistochemistry assay was positive for CD 20, CD 43, CD 79, AE1/AE3. The staging studies showed no evidence of both metastasis, Ann Harbor stage IE, without B symptoms. After RIT no further radiotherapy or chemotherapy was indicated. Nowadays the thyroglobulin is undetectable, without recurrences at two years of follow-up. It was concluded that primary thyroid MALT lymphoma is uncommon being the papillary thyroid carcinoma more frequent. Both occurring concomitantly is very rare and the treatment has to prioritize the tumor of worst prognosis at the discovery moment.

These patients were grouped by negative or positive serum Tg levels according to the American Thyroid Association guidelines. Results: Of the 60 included patients, 49 underwent radioactive iodine (RAI) treatment. Maximum unstimulated Tg (uTg) ≥ 0.2 ng/mL were associated with larger diameter of recurrent LNs (P = 0.027), and higher rate of metastatic LNs (P < 0.001). Serum-stimulated Tg (off-Tg) ≥ 1ng/mL (P = 0.047) and unstimulated Tg (on-Tg) ≥ 0.2 ng/Ml (P = 0.013) were associated with larger diameter of recurrent LNs. Number of metastatic LNs ≥ 8 was an independent predictor for postoperative maximum uTg ≥ 0.2 ng/mL (OR = 8.767; 95% CI =1.392-55.216; P = 0.021). Ratio of metastatic LNs ≥ 25% was an independent predictor for off-Tg ≥ 1 ng/mL (OR = 20.997; 95% CI =1.649-267.384; P = 0.019). Conclusion: Postoperative Tg-positive status was associated with larger size of recurrent LNs. Number of metastatic LNs ≥8 and ratio of metastatic LNs ≥ 25% were independent predicators for uTg-positive and off-Tg-positive status, respectively.
