Abstract
BACKGROUND Parathyroid carcinoma (PC) is the rarest endocrine cancer and an infrequent cause of primary hyperparathyroidism (PHPT), responsible for less than 1% of cases. Due to its rarity, treatment is challenging. METHODS A retrospective cohort study on 462 patients referred for parathyroidectomy to Thyroid and Parathyroid Unit at Santi Paolo e Carlo Hospital, Milan, Italy, from 2011 to 2021. We identified and individually described the patients affected with PC. Then, we split all patients treated for PHPT into four groups based on the cause: PC, adenoma, atypical adenoma, and hyperplasia. Patients' demographics, preoperative evaluation results, intraoperative findings, and outcomes for the PC group were compared with groups of PHPT due to benign causes. RESULTS Eight cases of PC were identified, five males and three females. Seven cases presented with symptoms of hypercalcemia and one with a neck mass. Five underwent en bloc resections and three local excisions. Histopathological features showed capsular invasion in four patients, capsular and soft tissue invasion in three patients, and vascular invasion in one case. No patients had distant metastasis. One patient was classed as high risk based on the Schulte classification system. All patients treated for PC were alive and disease-free at a mean follow-up of 38.4 months. When compared with other PHPT patients, PC patients were more frequently male and had higher preoperative blood calcium and PTH and lower phosphate levels, larger and heavier parathyroids excised, lower postoperative calcium, and a higher rate of postoperative hypoparathyroidism. CONCLUSION Our study highlights some aspects valuable to suspect PC and differentiate PHPT-PC from benign causes of PHPT preoperatively. Preoperative suspicion of malignancy is essential to guarantee the best course of treatment for patients. Although limited for size and follow-up, the excellent outcome of our series seems to support the value of both surgery extension and risk class according to the Schulte classification as possible prognostic factors for recurrence.

[PMID: 33721967 PMCID: PMC8217798 DOI: 10.14366/usg.20170] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Accepted: 12/22/2020] [Indexed: 12/14/2022] Open
Abstract
Purpose The aim of this study was to evaluate the efficacy of ethanol ablation (EA) in the treatment of cystic thyroid nodules using low-dose ethanol regardless of the initial volume of the nodule or properties of the aspirate. Methods Sixty-one nodules in 60 patients were treated with EA from October 2013 to January 2020. In each patient, EA was performed only once, using less than 5 mL of ethanol (99.5%) instilled and removed completely after a few minutes of retention. Nodule volume, the symptom score, the cosmetic score, and complications were evaluated before and after treatment. The therapeutic success rate (TSR) and volume reduction rate (VRR) according to nodule volume and properties of the aspirate were evaluated. Therapeutic success was defined as the absence of any residual fluid or sufficient volume reduction (≥50%) with improvement of nodule-related symptoms. Results The 61 nodules comprised 38 pure cysts and 23 predominantly cystic nodules. The initial nodule volume was 21.9±15.2 mL (range, 4.4 to 77.2 mL). The TSR was 88.5% (100% in pure cysts and 69.6% in predominantly cystic nodules, P<0.001). The TSR of pure cysts was 100% regardless of nodule volume and properties of the aspirate. In predominantly cystic nodules, the TSR and VRR gradually decreased as volume increased. One patient experienced arrhythmia during the procedure, but completely recovered without sequelae. Conclusion Single-session EA using low-dose ethanol might be effective for the treatment of symptomatic cystic thyroid nodules regardless of the initial cyst volume and properties of the aspirate, especially in pure cysts.

Abstract
Background To assess the efficacy and safeness of ultrasound guided lauromacrogol injection for ablation of benign cystic and predominantly cystic thyroid nodules. Methods From July 2016 to July 2018, 102 patients with 107 nodules were treated with ultrasound guided lauromacrogol injections for ablation and 43 nodules completed at least 12 months follow-up. Nodules sonographic characteristics, volume changes before and after USG-LIA, and complications were evaluated. Results Mean nodule volume decreased from 17.27 ± 20.51 ml to 5.35 ± 14.68ml (P < 0.05), and the overall resolution rate (volume reduction rate > 50%) was 91.67% in purely cysts and 75.90% in predominantly cystic nodules at the last follow-up. Within 6 months after treatment, the volume of the target nodule at each follow-up was smaller than the previous one (P < 0.001 for all). However, there was no significant difference of volume change between the 6th month and the 12th month. No severe complications occurred in this study. Conclusion Ultrasound guided lauromacrogol injection for ablation is an effective and safe treatment modality in both purely cystic and predominantly cystic thyroid nodules.

Abstract
BACKGROUND Parathyroid carcinoma is a rare neoplasm that may present sporadically or in the context of a genetic syndrome. Diagnosis and management are challenging due to the lack of clinical and pathological features that may reliably distinguish malignant from benign disease. METHODS From January 2013 to December 2017, from 358 consecutive patients affected by parathyroid diseases, 3 patients with parathyroid carcinoma were treated at our academic Department of General Surgery. We present our experience as illustrative of the different features of clinical presentation of parathyroid carcinoma and review its management considering the recent relevant literature. RESULTS Case 1: A 62-year-old man was hospitalized for left-sided palpable neck mass, hypercalcemia and elevated PTH. US-guided FNA was suspect for parathyroid carcinoma. A large cystic mass was excised in bloc with total thyroidectomy and central neck dissection. Genetic studies framed a pathologically confirmed parathyroid carcinoma within MEN1 syndrome. Case 2: A 48-year-old woman with hypothyroidism had total thyroidectomy performed for a suspect for right follicular thyroid lesion. Pathology revealed parathyroid carcinoma. Case 3: A 47 year-old man was admitted for hypercalcaemic crisis and renal failure in the context of PHPT. A lesion suggestive on US and MIBI scan for parathyroid adenoma in the right lower position was removed by mini-invasive approach. Pathology revealed parathyroid cancer and patient had completion hemythyroidectomy and central neck dissection. CONCLUSION Parathyroid cancer is a particularly rare endocrine malignancy, however it should be suspected in patients with primary hyperparathyroidism when severe hypercalcemia is associated to cervical mass, renal and skeletal disease. Parathyroid surgery remains the mainstay of treatment. Radical tumour resection and expedited treatment in a dedicated endocrine Center represent crucial prognostic factors.

Abstract
PURPOSE We compared the efficacy and safety of two ethanol ablation techniques-ethanol aspiration and ethanol retention-for benign cystic thyroid nodules. METHODS From October 2008 to September 2013, 113 patients who were treated using the ethanol aspiration technique (February 2008 to December 2010) and 108 patients who were treated using the ethanol retention technique (January 2011 to September 2013) were enrolled (male:female ratio, 53:168; mean age, 48.1 years; range, 18 to 80 years). The patient sample had 94 cystic and 127 predominantly cystic thyroid nodules. The volume reduction ratio (VRR) at the last follow-up, improvements in symptoms and cosmetic scores, vascularity, pain, and major complications were evaluated and compared between the ethanol aspiration group and ethanol retention group. We also performed a subgroup analysis according to the proportion of the solid component, in which VRR, symptom and cosmetic scores, and therapeutic success were compared. RESULTS No statistically significant difference in VRR was found between the ethanol retention group and the ethanol aspiration group (83.2%±32.8% vs. 86.1%±18.4%, P=0.416) while patients who underwent the retention technique were more likely to experience pain after treatment (P=0.001). VRR, symptom and cosmetic scores, and therapeutic success did not significantly differ between techniques in either group in the subgroup analysis. CONCLUSION The ethanol aspiration technique may be preferable to the ethanol retention technique for treating benign cystic and predominantly cystic thyroid nodules, because a comparable VRR can be expected with less pain.

Abstract
The standard treatment regimen for locally recurrent lesions is total thyroidectomy, or complete removal of the recurrent thyroid lesion within the thyroid bed. However, reoperation increases the risk of complications and patients have to undergo general anesthesia. Percutaneous ethanol injection therapy represents a far less invasive procedure without general anesthesia and with lower risk of complications. Thirty-four patients who received PEIT at Yonsei University Medical Center between October 2002 and August 2009 for recurrent cervical nodal metastases of differentiated papillary thyroid cancer were included in this retrospective study. During a minimum follow-up of 60 months, treatment outcomes were determined by measuring the lesion size prior to the first injection and 3 months after the last injection. A total of 46 recurrent lesions were detected in 34 patients. Five patients underwent surgery and PEIT was administered to the remaining 19 and 22 lesions in the central compartment and lateral neck lymph nodes, respectively. Size increases were observed in seven (17.1%) lesions, whereas no changes in size and decreases were detected in 10 (24.4%) and 24 (58.5%) lesions. Patients with increased lymph nodes were significantly older (65.3 ± 14.4 vs. 48.2 ± 16.3 years; p = 0.02) and had smaller sizes (9.3 ± 1.0 vs. 12.3 ± 6.4 mm; p = 0.012). Although reoperation remains the first-line treatment for recurrent thyroid cancer, PEIT may be considered as a treatment option in selected patients with lesions larger than 1 cm who are ineligible for surgery or have refused reoperation.

Abstract
PURPOSE Initial studies of combinations of radioiodine therapy (RIT) and local ablative procedures for the treatment of thyroid nodules have shown promising results. The goal of this study was to evaluate the effectiveness of RIT combined with radiofrequency ablation (RFA) in patients with goitres and to determine which ablative procedure is the most suitable for a combined therapy. METHODS Thirty patients with goitres were divided into two subgroups. A test group of 15 patients received combined therapy (RIT + RFA) and a control group of 15 patients received RIT mono therapy. All patients underwent assessments including ultrasound, laboratory evaluation (T3, T4, TSH, TG, TPOAb, TgAbTRAb) and scintigraphic imaging with Tc-99m-Pertechnetate. The 3-month volume reduction was used to evaluate therapy effectiveness. RESULTS Combined therapy (subgroup 1) resulted in a significant (p < 0.05) thyroid volume reduction (22.3 ± 54 ml/32.2 ± 58.2%) with better performance (p > 0.05) than the control group (20.2 ± 32.2 ml/29.6 ± 42.1%). All patients became euthyroid after treatment. No major discomfort or complications occurred. A review of the literature investigating combinations of other local ablative procedures with RIT was performed to determine the most promising combination. CONCLUSIONS The present study confirms the positive experiences with the combined therapy of RIT and local ablative procedures shown in the current literature and approves this approach for the treatment of goitres with RFA + RIT. These findings, when confirmed by further studies, should expand the indication of combined therapy as a minimally invasive alternative to surgery.

Abstract
Parathyroid carcinoma is one of the rarest known malignancies that may occur sporadically or as a part of a genetic syndrome. It accounts for approximately 1% of patients with primary hyperparathyroidism. The majority (90%) of parathyroid cancer tumors are hormonally functional and hypersecrete parathyroid hormone (PTH). Thus, most patients exhibit strong symptomatology of hypercalcemia at presentation. Sometimes, it can be difficult to diagnose parathyroid cancer preoperatively due to clinical features shared with benign causes of hyperparathyroidism. Imaging techniques such as neck ultrasound and 99mTc sestamibi scan can help localize disease, but they are not useful in the assessment of malignancy potential. Fine needle aspiration (FNA) prior to initial operation is not recommended due to technical difficulty in differentiating benign and malignant disease on cytology specimens and the possible associated risk of tumor seeding from the needle track. Complete surgical resection with microscopically negative margins is the recommended treatment and offers the best chance of cure. Persistent or recurrent disease occurs in more than 50% of patients with parathyroid carcinoma. Surgical resection is also the primary mode of therapy for recurrence since it can offer significant palliation for the metabolic derangement caused by hyperparathyroidism and allows hypercalcemia to become more medically manageable. However, reoperation is rarely curative and eventual relapse is likely. Chemotherapy and external beam radiation treatments have been generally ineffective in the treatment of parathyroid carcinoma. Typically, these patients require repeated operations that predispose them to accumulated surgical risks with each intervention. In inoperable cases, few palliative treatment options exist, although treatment with calcimimetics can effectively control hypercalcemia in some patients. Most patients ultimately succumb to complications of hypercalcemia rather than from tumor burden or infiltration.
