Diffuse Sclerosing Variant

Abstract Diffuse sclerosing variant (DSV) is a rare subtype of papillary thyroid cancer (PTC). Whether it represents a higher grade subtype than conventional PTC is not quite clear. Furthermore, there are limited data on its long-term outcome and its molecular genetics. In this report, we studied all cases of DSV PTC seen at our center during the last 20 years. Out of more than 6000 patients (pts) with differentiated thyroid cancer, only 37 were DSV. We reviewed the clinical and histopathological features, management and outcome of these cases. In addition, molecular genetics is partially achieved; 17 out of these 37 cases have been genotyped for BRAFV600E, TERT promotor mutations, NRAS, HRAS and KRAS mutations. The molecular profiling of the other 20 cases is being done. A total of 37 pts were studied {(12 Males:25 Females, median age 21 years (8-89)}. One pt had lobectomy and the other 36 pts (97.3%) had a total thyroidectomy. Central only (4 pts) or central/lateral lymph node dissection (29 pts) were performed. The median tumor size was 4.5 cm (1.5-8.1). The tumor was multifocal in 27 cases (73%), with extrathyroidal invasion in 27 (73%) and lymphovascular invasion in 24 pts (64.8%). A background lymphocytic thyroiditis was present in 12 pts (32.4%). Lymph node metastases were present in 34 pts (92%) and distant metastases in 13 pts (35%). The sites of metastasis are lungs in 12 pts (32.4%) and lungs and bone in 1 pt. Twenty pts (54.1%) were in TNM8 stage 1, 10 pts (27%) in stage 2, 1 (2.7%) in stage 4a, 3 (8.1%) in stage 4b and 3 unstageable. The ATA risk classification for these pts was 4 pts (10.8%) in low, 12 (32.4%) in intermediate, 19 (51.4%) in high-risk groups and 2 could not be assessed. I-131 was administered to 33 pts (89.2%). The median administered activity was 136 mCi (46-218). Fifteen pts (40.5%) received additional therapies (3 surgeries, 7 RAI, 5 surgeries, and RAI). In 17 pts (46%) which were genotyped, only 3 tumors (8.1%) had BRAFV600E mutation, 1 (2.7%) had TERT promotor C228T mutation and none had RAS mutations. At the last follow up, 15 pts (40.5%) achieved an excellent response, 9 (24%) an indeterminate response, 6 (16.2%) with a structural disease, and 7 (19%) were lost for follow up. Conclusion: DSV PTC is a rare variant, occurs mostly in adolescent and young pts, characterized by aggressive histopathological features and high rates of lymph node and distant metastases but the commonly reported mutations in PTC are rare in DSV and mortality is absent.

Thyroid cancer is the most common endocrine malignancy, presenting with 23 500 new cases per year in the United States. About 7-23% of the patients will present recurrent metastases disease during follow-up. The classic variant of papillary carcinoma is less aggressive compared to its other variants like diffuse sclerosing, tall cell or columnar cell, and insular variants, and the sites to which this metastasizes is already well identified. Metastasis to the spleen is an extremely rare manifestation of papillary thyroid cancer. To date, only 3 cases have been reported in the literature. Herein, we present a 52-year-old male, who developed spleen metastases, 2.4 years after total thyroidectomy and central neck dissection followed by radioactive iodine ablation and seven months after treatment with sorafenib for lung metastases. The splenic lesion was detected in surveillance studies. This case highlights that splenic metastasis, although rare, may occur even in a patient with a locoregional and systemic controlled thyroid cancer and that it can be treated safely with surgical resection.

Abstract Background: Minimally invasive video-assisted thyroidectomy (MIVAT) was introduced in the clinical practice to treat small benign thyroid nodules. This method has recently been demonstrated to produce the same completeness as a conventional thyroidectomy in patients with papillary thyroid cancer (PTC). The low number of treated cases and the limited follow-up of these patients represent the major limitations of these studies. Objective: The aim of the study was to compare the outcome of two groups of PTC patients, one treated with MIVAT and the other with conventional thyroidectomy, after a median follow-up of 5 yr. Study Group: A total of 221 PTC patients were enrolled in this study according to the following criteria: 171 were treated with MIVAT (group A), and 50 were treated with conventional thyroidectomy (group B). Results: The outcome and the cumulative 131I activity administered to achieve curative status were compared. After a mean follow-up of 3.6 ± 1.5 yr (range, 1–8 yr; median, 5 yr), no differences were found between group A and group B. A similar rate of permanent hypoparathyroidism and/or nerve cord palsy was found in both groups. Conclusion: We demonstrated that PTC patients operated on with MIVAT had a good outcome after 5 yr. This was similar to the outcome of patients treated with conventional thyroidectomy and the same degree of exposure to 131I. These results, together with the evidence of a similar degree of completeness and rate of complications between the two surgical techniques, show that MIVAT is a valid option to treat low- and intermediate-risk PTC patients.

Abstract Introduction: The occurrence of papillary thyroid cancer in patients with familial medullary thyroid cancer (FMTC) is extremely rare and underreported. Case Presentation: A 51-year-old caucasian female with no past medical history who presented to primary care physician for her annual visit. She denied any complaints. Vital signs were unremarkable. Physical examination was remarkable for large left thyroid nodule without cervical lymph nodes enlargements. Family history was significant for metastatic MTC of her two sisters (at the age of 55, 60) and her niece at age of 21. She previously declined genetic testing. Labs were unremarkable including serum calcium of 8.3 mg/dL. Thyroid function panel revealed a TSH of 2.1 μU/mL, Free T4 of 1.4 ng/dL, Thyroid peroxidase (TPO) antibody of <6 IU/mL. Neck ultrasonography revealed a mid-left thyroid hypoechoic nodule of 1.8 ×1.5 cm, without cervical lymph nodes enlargements. Fine needle biopsy revealed a papillary thyroid cancer, follicular variant. The diagnosis confirmed by two university pathologists, without any evidence of MTC. Genetic testing revealed a germline mutation in RET oncogene exons 13. Further labs revealed normal metanephrines of 12 pg/mL and normal normetanephrine of 31 pg/mL, normal serum calcitonin was less than 2 pg/mL (0-5), normal serum CEA was 2.5 ng/mL (0-5), elevated anti- thyroglobulin (anti-TG) antibodies of 1234 iu/mL (0-0.9), and elevated thyroglobulin of 50 ng/mL (1.5-38.5). The patient was referred to ENT for total thyroidectomy. Further, she was treated with radioactive iodine ablation by 155 mCi of iodine 131. Follow up whole body thyroid scan revealed no evidence of residual or recurrence. The patient was treated with 112 mcg levothyroxine with a target of TSH less than 0.1. On six months follow up, repeated neck ultrasonography revealed no remnant of thyroid tissue. Follow up Thyroglobulin (TG) was less than 0.1 ng/mL, TSH 0.05 μU/mL, FT4 of 1.98 ng/dL, and calcitonin was still less than 2 pg/ml. Genetic testing of her daughters (24, 31) revealed germline mutations in RET-oncogene exons 13 and was referred for prophylactic thyroidectomy. Discussion: FMTC is an inherited syndrome characterized by the presence of only MTC without hyperparathyroidism or pheochromocytoma and is considered a variant of MEN2A. Most cases of MEN2A have been attributed to mutations in the intracellular portion of RET, and somatic mutations in RET have been identified in 50% of cases of sporadic FMTC. We recommend in patients with germline RET mutations and a family history of MTC, the diagnosis of papillary thyroid cancer should be confirmed by two pathologists, and patients should be tested for serum calcitonin, serum calcium, and metanephrines/normetanephrine levels. Genetic testing of first-degree relatives of FMTC at an early age is essential in guiding major management decisions such as the timing of prophylactic thyroidectomy.
