The Role of Calcitonin in Predicting the Extent of Surgery in Medullary Thyroid Carcinoma: A Nationwide Population-Based Study in Norway

Background: Preoperative predictors for the need of prophylactic lymph node dissection in the lateral neck have been studied in patients with medullary thyroid carcinoma (MTC). Objectives: To evaluate the ability of serum calcitonin to predict the extent of surgery needed in the lateral neck. Methods: This retrospective population-based cohort study includes data from 94 of 139 patients with MTC surgically treated in Norway from 2003 to 2016. Patients were identified in the 4 regional centers treating MTC and by the Cancer Registry of Norway, and grouped according to calcitonin levels. In 58 patients without distant metastases or disease progression to the next tumor level (NPNL), data were compared in prognostic groups (N0-NPNL), (N1a-NPNL), and (N1b-NPNL). Results: At calcitonin levels ≤500, 501–1,000, and >1,000 pmol/L, metastatic lymph nodes in the lateral neck were found in 16, 50, and 71% of the patients, respectively. In the prognostic groups, 19% of N0-NPNL patients had calcitonin >500 pmol/L and 17% of N1b-NPNL patients had calcitonin ≤500 pmol/L. In multivariate analysis, factors predicting biochemical cure and calcitonin level ≤500 pmol/L were no metastatic lymph nodes in the lateral neck (p = 0.030) and tumor diameter ≤20 mm (p < 0.001), respectively. Factors related to metastatic lymph nodes in the lateral neck were extrathyroidal extension (p = 0.007) and no biochemical cure (p = 0.028). Conclusions: Basal calcitonin cannot predict the need for prophylactic lateral lymph node dissection in patients with MTC. Further prospective, randomized studies are warranted.

The role of thymus preservation in parathyroid gland function and surgical completeness after bilateral central lymph node dissection for papillary thyroid cancer: A randomized controlled study

BackgroundThe clinical value of thymus preservation during thyroid carcinoma surgery remains unclear. The aim of this study is to explore the role of bilateral thymus preservation in parathyroid glands (PGs) function and surgical completeness in total thyroidectomy (TT) with bilateral central lymph node dissection (CLND). Materials and methodsFifty-four consecutive patients who underwent TT and bilateral CLND were assigned to the thymus preservation (TP) group (n = 27) and the bilateral thymectomy (BT) group (n = 27). Surgical completeness was evaluated by the number of lymph nodes dissected, serum Tg level and ultrasound findings postoperatively. ResultsIncidental parathyroidectomy was more common in the BT group (29.6% vs 7.4%, p = 0.038). Patients in the BT group had higher risks of neuromuscular symptoms (63.0% vs 29.6%, P = 0.014) and transient hypoparathyroidism (70.4% vs 25.9%, P = 0.001). The incidence of persistent hypoparathyroidism failed to show a significant difference between the TP and BT groups (0 vs 14.8%, P = 0.111). However, those with transient hypoparathyroidism in the BT group had a lower level of serum PTH at 3 weeks postoperatively (p = 0.001). There was no significant difference in the number of lymph nodes dissected (5.89 ± 3.12 vs 8.56 ± 6.93, P = 0.077) and preablation sTg level (1.82 ± 2.18 vs 1.42 ± 1.56 ng/ml, P = 0.775) between the TP and BT groups. No metastatic lymph nodes were found on sonography at 3 months postoperatively in both groups. Conclusion: Thymus preservation had benefits on protecting PGs and promoting rapid clinical resolution of hypoparathyroidism. It had no effects on oncologic completeness of TT with bilateral CLND.

Image Guided Ablations for Thyroid Tumours

Image guided ablations might be regarded as a promising effective and safe alternative for treatment of recurrent thyroid cancer in particular in patients with high surgical risk or refusing surgery. Furthermore, image guided ablations seems to represent a promising alternative to surgery or observation for micropapillary thyroid carcinoma, with the aim of providing an effective treatment with minimal invasiveness. Further studies are necessary to confirm the role in this setting

Central compartment revision surgery for persistent or recurrent thyroid carcinoma: analysis of survival and complication rate.

Locoregional recurrence of thyroid carcinoma is relatively common and reported rate are between 5 and 20%. Cervical nodes are usually involved, especially at the central compartment. The management of recurrent thyroid carcinoma at central compartment still remains challenging because of higher incidence of complication rate. The aim of the study is to evaluate the survival and complications rate after revision surgery. Retrospective cohort study on a group of patients that underwent revision surgery for persistent or recurrent thyroid carcinoma from January 1, 2003 to December 31, 2017. Survival outcomes were calculated using Kaplan-Meier method. Significant variables on univariate analysis were subjected to a Cox proportional hazards regression multivariate model. Fifty-two patients involved, 22 male (40%) and 30 female (60%). Mean age was 54years old (range 24-85). Mean follow-up was 79 months, median follow-up was 85 months, with a range between 8 and 153months. The 5-year overall survival was 90.8% while at 10years it was 69.8%. The 5-year disease-specific survival was 93.5%, while at 10years it dropped to 77.9%. The rate of recurrent laryngeal nerve paralysis and persistent hypocalcemia in our series were 1.3% and 5.9%, respectively. No evidence of thoracic duct, esophageal or laryngeal and tracheal injury was found in this case series. Regarding prognostic factors, univariate and multivariate analysis highlighted as statistically significant: the aggressive histological variants, the presence extranodal extension or soft-tissue metastasis. The surgical option remains the gold standard in locoregional recurrences of thyroid carcinoma and should be performed by experienced surgeons to reduce postoperative complications.

Well-differentiated tireoid carcinoma: epidemiological profile, surgical results and oncological response.

to know the epidemiological profile of patients undergoing surgery for well-differentiated thyroid carcinoma at the Cassiano Antônio Moraes University Hospital of the Federal University of Espírito Santo, as well as the oncological results and the main postoperative complications. we conducted a cross-sectional, retrospective study of patients with well-differentiated thyroid carcinoma (WDTC) operated from January 2008 to December 2015. During the study period, 95 of the 353 patients undergoing surgical treatment of the thyroid gland had WDTC. Papillary carcinoma was the most frequent (91.57%). Total thyroidectomy not associated with cervical emptying was the most frequent surgical procedure (65.26%). Postoperative complications occurred in 6.31% of patients, hematoma being the most frequent. The mean follow-up time was 36.9 months. Relapse occurred in four patients (4.21%), being locoregional in all cases. The prognostic factors analyzed, such as gender, age, tumor size, lymph node involvement, staging, type of surgery, histology and complementary iodine therapy did not show statistical significance. papillary carcinoma was the most common thyroid malignant neoplasm, affecting women in the 49-year-old age group more frequently. Loco-regional recurrence occurred in four patients. Hematoma was the most frequent complication.

Live birth following laparoscopic fertility-sparing surgery for papillary thyroid carcinoma arising from mature ovarian cystic teratoma: A case report.

Papillary thyroid carcinoma arising from ovarian mature cystic teratoma is clinically rare. We herein present a case of live birth following two laparoscopic surgeries for papillary thyroid carcinoma arising in a mature ovarian cystic teratoma. A 30-year-old female patient, gravida 1 para 1, was treated by laparoscopic bilateral ovarian cystectomy for suspicion of bilateral mature cystic teratoma. The diagnosis of papillary thyroid carcinoma arising from right ovarian mature cystic teratoma was established based on postoperative pathological examination of the tumor. Such rare neoplasms may be difficult to diagnose preoperatively based on radiological examinations alone. The patient underwent laparoscopic fertility-preserving unilateral (right) salpingo-oophorectomy. Following an extensive discussion with the patient and her family, appropriate informed consent was obtained for the treatment option and the patient and her family chose to preserve her fertility. She could have a baby following the treatment and no evidence of disease for 6 years. Gynecologists should be aware of the possibility of such rare cases, and the available surgical interventions should be fully discussed with patients who wish to preserve their fertility. Laparoscopic fertility-sparing surgery may be a feasible option when encountering such a rare condition.

Synchronous and antecedent malignancies in patients with papillary thyroid carcinoma

Objective. This study aimed to evaluate concurrently detected second primary malignancy in the patients who underwent surgery for papillary thyroid carcinoma. Methods. In this study, we retrospectively analyzed the files of the patients who underwent surgery for papillary thyroid carcinoma between 2000-2017. A total number of 601 patients with papillary thyroid carcinoma were evaluated. Among these patients, 48 patients were found to have secondary primary tumors. Preoperative and postoperative laboratory examination findings of the patients were retrospectively recorded. Results. Among 601 patients with papillary thyroid cancer evaluated with respect to radiation exposure, the second primary tumor with breast cancer was found to be the most common tumor. Renal cell carcinoma, malignant melanoma and stomach cancer were found to be more frequent when evaluated regardless of radiation effect. Furthermore, when molecular genetic results were evaluated, BRAF mutation rate was found to be more frequent than in other secondary tumors, especially in patients with renal cell carcinoma. Conclusions. The importance of epidemiological and experimental studies of multiple cancers is obvious. Although it is known that the impact of radiation is considerable among the ones with concurrence of breast cancer and papillary thyroid carcinoma, we suggest that further studies on common molecular genetic characteristics and development of targeted treatment for detected molecules are required in the patients with renal cell carcinoma in whom papillary thyroid carcinoma is diagnosed regardless of radiation effect.

Hemithyroidectomy for low-risk follicular carcinoma of the thyroid: results from a regional hospital.

Excellent outcomes after conservative thyroid surgery for low-risk follicular thyroid carcinoma (FTC) have been reported from highly specialised centres. However, it is uncertain whether low-volume hospitals can achieve similar treatment results. At our institution, 49 patients with FTC were treated during the period 1991-2014. Patients with minimally invasive FTC (MIFTC) were usually treated with hemithyroidectomy. The demographic data, pathology, treatment modality and oncological outcomes of these patients were retrospectively evaluated. The tumours were classified as Stage I in 40.8% of patients, Stage II in 32.7%, Stage III in 20.4% and Stage IV in 6.1%, according to the TNM classification system. Only 4 (8.2%) patients had widely invasive FTC (WIFTC). Vascular invasion or capsular invasion alone occurred in 9 (19.1%) and 19 (40.4%) patients, respectively, while 19 (40.4%) patients had simultaneous vascular and capsular invasions. 34 (69.4%) patients with MIFTC initially underwent hemithyroidectomy, while 15 (30.6%) patients underwent total thyroidectomy. Ten patients who underwent total thyroidectomy received radioactive iodine ablation. The mean follow-up duration was 86.9 ± 56.6 months. There was no disease-specific mortality, although two patients with WIFTC remained alive with disease at the end of the study. The five-, ten- and 15-year overall survival rates were 95%, 91% and 84%, respectively. Five patients from the hemithyroidectomy group died due to other illnesses with no evidence of FTC. Satisfactory disease control and excellent survival for MIFTC is achievable by hemithyroidectomy in community hospitals. Total thyroidectomy should be reserved for WIFTC or aggressive tumours with nodal or distant metastasis.

Thyroidectomy Practice After Implementation of the 2015 American Thyroid Association Guidelines on Surgical Options for Patients With Well-Differentiated Thyroid Carcinoma

The recommended extent of surgery for well-differentiated thyroid carcinoma has been modified considerably in the updated 2015 American Thyroid Association guidelines published in January 2016. To date, the changes in clinical practice after publication of these new guidelines have not been demonstrated. The aim of this study was to evaluate clinical practice changes associated with implementation of the updated guidelines on the surgical procedure rates of total thyroidectomy, thyroid lobectomy, and completion thyroidectomy at a single tertiary medical center. This is a retrospective cohort study of 169 patients at the Hadassah-Hebrew University Medical Center, Jerusalem, Israel. Patients with pathologically proved, well-differentiated thyroid carcinoma who underwent surgery between January 1, 2013, and December 31, 2014, were compared with patients who underwent surgery from January 1 to December 31, 2016. A total of 434 thyroidectomy procedures were performed during the study period, and 251 had pathologically proved, well-differentiated thyroid carcinoma. Patients with tumors larger than 4 cm, involved lymph nodes, or bilateral nodules were excluded. Primary outcomes were the rate of up-front total thyroidectomy vs lobectomy and the rates of completion thyroidectomy before and after the implementation of the new guidelines. Of the 169 patients in the final analysis, 118 (69.8%) were included from 2013 to 2014 and 51 (30.2%) in 2016. The mean (SD) age for the entire cohort was 44 (13.8) years, and 129 (76.3%) were women. Up-front total thyroidectomy was performed in 72 of 118 patients (61.0%) prior to the 2015 American Thyroid Association guidelines and 16 of 51 (31.4%) following their implementation (odds ratio, 0.29; 95% CI, 0.14-0.59). The rate of completion thyroidectomy also significantly decreased between these periods (73.9% vs 20.0%; odds ratio, 0.09; 95% CI, 0.04-0.19). The updated 2015 American Thyroid Association guidelines implementation was associated with a significant decrease in the rates of both up-front total thyroidectomy and completion thyroidectomy. According to these findings, only 1 of 5 patients who undergoes thyroid lobectomy will require a completion procedure.

Individualizing Surgery in Papillary Thyroid Carcinoma Based on a Detailed Sonographic Assessment of Extrathyroidal Extension.

Lobectomy may be sufficient for patients with intrathyroidal papillary thyroid carcinomas (PTC) <4 cm without nodal metastasis. Based on the 2015 American Thyroid Association guidelines, a strategy using ultrasound to identify appropriate candidates for lobectomy was implemented. Patients with Bethesda V or VI cytology who underwent surgery for PTC (January 2016 to May 2017) were retrospectively reviewed. Eligibility for lobectomy was based on both tumor (unilateral, intrathyroidal tumors ≤3 cm in size) and non-tumor (history of hypothyroidism, radiation exposure, etc.) characteristics. A detailed sonographic assessment of extrathyroidal extension (ETE) included surgeon-performed evaluation of thyroid capsular distortion, a long interface between tumor and thyroid capsule, irregular or indistinct tumor margins abutting the thyroid capsule, or a tracheal footprint. Of 141 patients with PTC, 35 (25%) patients were candidates for lobectomy, and 105 (75%) patients were not candidates for lobectomy because of non-tumor (n = 46) or tumor (n = 59) characteristics. Of the 35 patients who were candidates for lobectomy, 27 had sonographic ETE on detailed assessment. Total thyroidectomy was performed in 23 patients, while thyroid lobectomy was performed in 12 patients. Total thyroidectomy was indicated based on final histopathology in 15 patients (ETE, aggressive histology, vascular invasion, or cervical metastasis). Histopathologic ETE was present in 13 of these 15 patients and was the only indication for total thyroidectomy in the remaining eight patients. Positive and negative predictive values for the prediction of ETE based on detailed sonographic assessment were 52% and 100%, respectively. In comparison to a strategy of routine total thyroidectomy, a detailed sonographic assessment of ETE reduced the rate of potentially avoidable total thyroidectomy from 57% to 31%. Patients with PTC who are potential candidates for lobectomy often require total thyroidectomy based on microscopic ETE detected on surgical pathology. A detailed sonographic assessment of ETE can reliably rule out microscopic ETE, reducing the rate of potentially avoidable total thyroidectomy.

Long-Term Outcome After Surgery for Medullary Thyroid Carcinoma: A Single-Center Experience.

Medullary thyroid carcinoma (MTC) is a rare C cells-derived tumor, with a hardly predictable long-term prognosis. This study was aimed to evaluate the predictive factors of cure and survival after surgery for MTC in a monocentric series. A retrospective analysis of the long-term outcomes was assessed in 255 MTC patients operated between 1980 and 2015 at Padua University hospital. Sporadic MTC occurred in 65.1% and hereditary MTC in 34.9% of patients. At a median follow-up of 93months (range 7-430), the cure rate was 56.8%. The overall 10-year survival was 84.4%, and MTC-related death rate was 15.3%. Patients who died because of MTC had a median age of 61years (range 21-84) and were at stages III-IV in all cases; deaths occurred in 18% of sporadic MTC, 6% of MEN2a and 66.7% of MEN2b patients. None of the patients at stages I-II died because of the disease, but 17.7% had persistent/recurrent disease. Based on univariate analysis, age, gender, genetic variant, extent and year of surgery, tumor size, lymph-nodal metastases and tumor stage significantly affected cure and survival rates. At multivariate analysis, only patient- and tumor-related features (age, lymph-nodal status and stage) remained significant independent prognostic factors. Radical surgery is the only chance of definitive cure in MTC, but it is possible only at early stage; in advanced stages, even extensive surgery could not grant cure and prolonged survival. Stage, nodal metastases and age remain the main predictive factors for cure and survival.

Partial resection and reconstruction of the sternum for treatment of metachronous sternal metastasis of thyroid carcinoma

Rationale:Metachronous sternal metastasis of thyroid carcinoma was a rare disease. There was no consensus in the treatment for bone metastasis after the initial thyroid carcinoma surgery.Patient concerns:A 53-year-old female patient was hospitalized due to recurrent dull chest pains, with a history of radical right side thyroid carcinoma 4 years ago. On examination, there was an irregular mass on the lower left half of the sternum. Computerized tomography scan showed sternal bone destruction with a soft tissue mass.Diagnoses:Metachronous sternal metastasis of thyroid carcinoma.Interventions:Partial resection of the sternum and reconstruction with a titanium alloy mesh were performed.Outcomes:After a 3-year follow-up, the patient had no recurrence.Lessons:Surgical resection may be a sufficient treatment for metachronous sternal metastasis of thyroid carcinoma. Biosynthesis material mesh is preferred to be used.

Selective sentinel lymph node biopsy in papillary thyroid carcinoma in patients with no preoperative evidence of lymph node metastasis

IntroductionLymphadenectomy is recommended during surgery for papillary thyroid carcinoma when there is evidence of cervical lymph node metastasis (therapeutic) or in high-risk patients (prophylactic) such as those with T3 and T4 tumors of the TNM classification. Selective sentinel lymph node biopsy may improve preoperative diagnosis of nodal metastases. ObjectiveTo analyze the results of selective sentinel lymph node biopsy in a group of patients with papillary thyroid carcinoma and no evidence of nodal involvement before surgery. Patients and methodA retrospective, single-center study in patients with papillary thyroid carcinoma and no clinical evidence of lymph node involvement who underwent surgery between 2011 and 2013. The sentinel node was identified by scintigraphy. When the sentinel node was positive, the affected compartment was removed, and when sentinel node was negative, central lymph node dissection was performed. ResultsForty-three patients, 34 females, with a mean age of 52.3 (±17) years, were enrolled. Forty-six (27%) of the 170 SNs resected from 24 (55.8%) patients were positive for metastasis. In addition, 94 (15.6%) out of the 612 lymph nodes removed in the lymphadenectomies were positive for metastases. Twelve of the 30 (40%) low risk patients (cT1N0 and cT2N0) changed their stage to pN1, whereas 12 of 13 (92%) high risk patients (cT3N0 and cT4N0) changed to pN1 stage. ConclusionsSelective sentinel lymph node biopsy changes the stage of more than 50% of patients from cN0 to pN1. This confirms the need for lymph node resection in T3 and T4 tumors, but reveals the presence of lymph node metastases in 40% of T1–T2 tumors.

Macrometastasis in Papillary Thyroid Cancer Patients is Associated with Higher Recurrence in Lateral Neck Nodes.

The use of routine central compartment neck dissection surgery for papillary thyroid carcinoma (PTC) is controversial. Although macroscopic central neck lymph node metastasis (CNLN) in PTC is a poor prognostic factor correlated with increased loco-regional recurrence, the significance of microscopic metastasis to the central lymph nodes is not established. Herein, we aimed to assess the influence of the size of CNLN on disease recurrence among PTC patients. Data from 233 patients who underwent less than total thyroidectomy with CNLN dissection in 1989-1999 were retrospectively reviewed. The patients were assigned to three groups according to the central node metastasis: no metastasis (Group I), micrometastasis (<2mm, Group II), and macrometastasis (≥2mm, Group III). Clinicopathological features, recurrence rate, site of recurrence, and disease-free survival (DFS) were assessed. Of the 233 patients enrolled (mean follow-up period, 16.1years), 134 (57.5%) had no central neck metastasis, 37 (15.9%) had micrometastasis, and 62 (26.6%) had macrometastasis. Demographics and tumour variables were similar among the three groups. Recurrence rates were 12.7, 16.2, and 43.5% in Groups I, II, and III, respectively (p<0.001). Group III had a 3.2-fold increased relative risk of recurrence and a significantly decreased DFS compared to Group I. Group III showed significantly higher rates of lateral neck nodes metastasis than Groups I and II. In conclusion, macrometastasis significantly affects disease recurrence in PTC patients, whereas microscopic metastasis has only marginal effects. Macroscopic CNLN metastasis showed a significantly higher recurrence in the lateral neck node compared to micrometastasis.

Transoral endoscopic surgery for papillary thyroid carcinoma: initial experiences of a single surgeon in South Korea.

PurposeThe transoral endoscopic thyroid surgery vestibular approach (TOETVA) is one of the newest techniques which do not result in an anterior neck scar. We report herein our initial experience with TOETVA and its short-term outcomes in patients with papillary thyroid carcinoma (PTC).MethodsThis case series consisted of all consecutive patients who underwent TOETVA in our institution between August 2016 and June 2017. Indications for TOETVA were an fine needle aspiration-confirmed PTC or follicular neoplasm, an intrathyroidal tumor with a diameter of less than 2 cm, and no clinical evidence of central or lateral lymph node metastasis. A total of 20 patients underwent TOETVA and we retrospectively reviewed clinicopathologic data and short-term postoperative outcomes.ResultsAmong the 20 TOETVA cases, 7 were total thyroidectomy, 12 were lobectomy and 1 was wide isthmusectomy. Mean age was 50.8 years and mean operation time was 152 ± 51.4 minutes. Tumor size ranged from 0.2–1.4 cm and the mean size of harvested central lymph nodes was 2.8 (range, 0–10). Neither mental nerve injury nor surgical site infection occurred. One patient had transient vocal cord palsy and 1 patient developed a neck seroma. Among 7 total thyroidectomy patients, 3 patients developed transient hypocalcemia.ConclusionTransoral thyroid surgery could be an alternative surgical option for some PTC patients.

Follicular thyroid carcinoma presenting as skull metastasis: A rare case report and literature review

Follicular thyroid carcinoma (FTC) is considered to be a well-differentiated thyroid carcinoma since it shows a low progression. Metastases occur in advanced stage by hematogenous route. Lung and bone are the two most common sites of metastases. In most of the reported cases of FTC metastasizing to the skull, metastases occurred long time after the diagnosis and establishment of adequate treatment for the primary cancer. Very few cases have been reported with FTC presenting as skull metastasis. We report the case of a 35-year-old female patient presented with a massive swelling of the right parietal skull region. Histopathologic examination confirmed that it is a FTC bone metastasis. A gross total resection of the tumor was performed. Two months later, a total thyroidectomy and lymph node resection were performed. The patient underwent radioactive-iodine (RAI) therapy and was given adjunctive Levothyroxine therapy. Five years of follow-up did not show any recurrence of the disease. Correct diagnosis of skull metastasis from preoperative FTC is difficult because of its rarity. Patients can survive several years after the therapy including total resection of metastatic tumor, radical operation of thyroid carcinoma, and adjunctive therapy by Levothyroxine and RAI therapy.

Clinical Features and Factors Affecting Prognosis of Papillary Thyroid Carcinoma in Male Patients

Background and Objectives: National cancer center institute reports that male patients of papillary thyroid carcinoma (PTC) are annually increasing. This study aimed to analyze the features of the male patients with PTC. Materials and Method: We retrospectively reviewed and analyzed clinical records of 170 patients who were treated for PTC in male patients between 2000 and 2010. Clinical features, size, pathologic type, extrathyroidal extension, recurrence, multiplicity, extent of surgery, and lymph node metastasis were retrospectively evaluated.Univariate and multivariate analyses of various clinical factors were performed. Results: Total 4145 patients received surgery for papillary thyroid carcinoma. The number of male patients was 170 (4.1%) among them. Of170 male patients, only 16(9.4%) patients underwent the recurrence of PTC. The size of tumor, central neck node metastasis, lateral neck node metastasis, extrathyroidal extension and RAI ablation therapy were associated with recurrence(p< 0.05) in univariate analysis. However, only the extrathyroidal extension [p=0.03, Odds ratio=3.58(95% CI. 1.09~14.24)] was related to the recurrence in multivariate analysis. Conclusion: Re-estimation of clinical features in male PTC patients should be concerned. The recurrence of PTC in male patients was 16(9.4%) and nearly same as the other studies. The extrathyroidal extension was revealed as an associated factor for the recurrence. Evaluation of regional or distant metastasis should be considered in patients with the extrathyroidal extension in male PTC patients during long-term follow-up.

High prevalence of self-reported shoulder complaints after thyroid carcinoma surgery.

Shoulder complaints are frequently reported after surgical treatment for thyroid carcinoma. However, no specific literature on this topic is available for these patients and, hence, its impact on quality of life (QOL) is unknown and there are no known predictors of shoulder complaints in this specific patient population. Therefore, the purpose of this study was to assess the prevalence of shoulder-related complaints and its relation to QOL and clinical characteristics after thyroid carcinoma surgery by means of a cross-sectional case control study in a tertiary referral center. The prevalence of shoulder complaints and its relation to clinical characteristics and QOL after thyroid carcinoma surgery (n = 109) was compared to a healthy control group (n = 81). Main outcome measures are prevalence of self-reported shoulder complaints, results of the Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH), and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30-questions (EORTC-QLQ-C30). Patients with thyroid carcinoma, on average 10.2 years after thyroid surgery, reported a 58.7% prevalence of shoulder-related complaints, which was significantly more than the 13.6% reported by healthy controls (p < .01). Patients with thyroid carcinoma scored worse than healthy controls on most of the different subscales of the DASH and EORTC-QLQ-C30. Bivariate association analysis identified level V neck dissection as being associated with the prevalence of shoulder complaints and the DASH score, and spinal accessory nerve damage and employment status as being associated with the DASH score. Prevalence of shoulder complaints and the DASH scores were significantly correlated to several EORTC-QLQ-C30 scores. Only 11.9% of patients with thyroid carcinoma retrospectively reported having received preoperative information on possible shoulder complaints and only 34.9% of patients with thyroid carcinoma retrospectively reported having received additional care for their shoulder complaints. Shoulder complaints represent and underestimated problem and are reported by many patients who had surgery for thyroid carcinoma. Information provision to the patient should be improved, shoulder complaints should be registered, and additional care should be provided after thyroid carcinoma surgery to improve QOL. © 2016 Wiley Periodicals, Inc.
