Experiential student study groups: perspectives on medical education in the post-COVID-19 period.

BACKGROUND: Undergraduate medical curricula often fail to integrate experiential learning methodologies. Thus, a pilot series of interactive pathology lessons was designed and implemented in an attempt to promote experiential learning. METHODS: Thirty pre-graduate medical students voluntarily participated in the interactive study groups at the First Department of Pathology of the National and Kapodistrian University of Athens, Medical School. A questionnaire was designed to investigate the satisfaction of students regarding their participation in pathology study groups and to identify the characteristics that shape students' perceptions of the foundations of medical education. Descriptive statistics (mean values) were used to describe the students' evaluations of the pathology study groups, and thematic analysis was conducted to investigate the data collected using open-ended questions. RESULTS: Interactions with the professor and the option of co-observing the slides using dual-view optical microscopes and virtual slides were each evaluated as "Excellent" by ≅ 95% of the students. Four overarching themes were identified regarding the core characteristics of medical education according to the students' perspectives: 1) educational background in medical education, 2) interaction with educators in medical education, 3) educational material in medical education and 4) assessment in medical education. CONCLUSIONS: The high rates of acceptance of the pathology study groups reflect the desire and need for active learning methodologies to be implemented in modern medical education. Nearly all the students mentioned the need for practical skill acquisition, the integration of theory into practice and ethics in medical education. The success of these optional pathology study groups highlights the need for similar modalities to be incorporated into the main medical education curriculum.

Surgical management of primary hyperparathyroidism during pregnancy: a systematic review of the literature.

OBJECTIVE: Gestational primary hyperparathyroidism (PHPT) is an endocrinological disorder with serious outcomes for both women and neonates. The aim of our study was to present the current evidence concerning the perioperative outcomes of pregnant women with PHPT who underwent parathyroidectomy during pregnancy. METHODS: A meticulous systematic review of the literature published before February 2020 and all studies which presented perioperative and pregnancy outcomes off pregnant women who underwent parathyroidectomy for PHPT, were included. RESULTS: A total of 53 were finally included, which reported 92 pregnant women who had parathyroidectomy during their pregnancy. A total of 46 patients were hospitalized due to significant complications of PHPT before their parathyroidectomy. With regards to surgical approach, 52.2% of patients underwent minimally invasive parathyroidectomy (MIP), while bilateral neck exploration (BNE) was 41.3% of cases. Only 4 women was not cured, whereas transient hypocalcemia was occurred in 18 patients. All cases proceeded to deliveries of healthy neonates, after their parathyroidectomy. CONCLUSIONS: Parathyroidectomy during pregnancy is a safe and effective treatment option with minimum complications and probably should be considered as the treatment of choice in specific group of pregnant women with PHPT.

Giant Ovarian Thecoma Associated with Meigs Syndrome: A Striking Case.

Introduction: Meigs syndrome consists of the presence of a benign ovarian tumor, ascites and pleural effusion, and the latter two subdued after surgical excision of the ovarian tumor. Elevated Ca-125 in this context is confusing and is reported only in a handful of cases. A rare but striking case with the above features is presented herein. Case Presentation: A 46-year-old woman with a giant pelvic/abdominal mass originating from her right adnexa, ascites and pleural effusion, with elevated Ca-125 (938 IU/mL) was treated with the presumptive diagnosis of stage IV ovarian cancer. Imaging modalities showed a 22 cm solid adnexal mass and the patient underwent total abdominal hysterectomy and bilateral salpigooophorectomy, omentectomy and drainage of 4L of ascetic fluid. Surprisingly, final histopathology was negative for malignancy, characterizing the primary tumor as ovarian thecoma. Ascites and pleural effusion resolved by the seventh postoperative day, setting the diagnosis of Meigs syndrome. Discussion: Meigs syndrome accounts for 1% of all ovarian tumors, however it should be considered in the differential diagnosis when clinicians come across the classic triad of the syndrome, even when Ca-125 is elevated. These patients have normal life expectancy with meticulous management, while pathophysiology of this condition remains uncertain in various points.

The impact of preoperative sarcopenia on postoperative complications following esophagectomy for esophageal neoplasia: a systematic review and meta-analysis.

Esophageal cancer is characterized by profound changes in body composition due to dysphagia and generalized cachexia. Sarcopenia or muscle wasting is a component of cachexia associated with poor postoperative performance status. The skeletal muscle index (SMI) calculated by computed tomography scans at the level of the third lumbar vertebra is an easily quantifiable and reproducible measure of sarcopenia. The aim of this meta-analysis is to investigate the impact of preoperative sarcopenia (low SMI) on postoperative complications after esophagectomy for neoplastic lesions. In this context, a comprehensive literature search was undertaken to identify studies reporting short-term postoperative outcomes in relation to their preoperative SMI values. Cumulative risk ratios (RR) and risk differences (RD) and their respective 95% confidence intervals (CIs) were calculated using a random-effect model. A total of 11 studies incorporating 1,979 total patients (964 patients with sarcopeniaversus 1,015 without sarcopenia) were included in the final analysis. The results demonstrated a significant increase in overall morbidity (RR 1.16, 95% CI 1.01-1.33), respiratory complications (RR 1.64, 95% CI 1.21-2.22) and anastomotic leaks (RR 1.39, 95% CI 1.10-1.76) in patients with sarcopenia. No statistically significant difference was noted in overall mortality (RD 0, 95% CI -0.02-0.02) or Clavien-Dindo grade III or greater complications (RR 1.17, 95% CI 0.96-1.42). The above results demonstrate the validity of the SMI as a predictive factor for post-esophagectomy complications. Although the risk associated with sarcopenia is not prohibitive for surgery, patients with low SMI require closer vigilance during their postoperative course due to the increased propensity for respiratory and anastomotic complications.

Reversal of Acute Mesenteric Ischemia by Salvation of the Meandering Mesenteric Artery with Stenting of the Left Internal Iliac Artery.

The presence of the meandering mesenteric artery, which is a nonconstant tortuous arterial component unifying the peripheral intestinal circulation, is evidence of chronic occlusive disease of the main intestinal arteries. This collateral intestinal arterial pathway, when present, must be preserved in any abdominal intervention, as it is often the only remaining arterial supply of the intestine; its ligation can be accompanied by intestinal ischemia. We present herein, the case of a 42-year-old man, heavy smoker, who had chronic mesenteric ischemia without particular clinical manifestations till the hospitalization for acute myocardial infarction for which he underwent balloon angioplasty and stenting of the left circumflex coronary artery. Three days later, he experienced acute-on-chronic intestinal ischemia with crescendo clinical manifestations; intra-arterial angiography revealed the presence of a meandering mesenteric artery in a milieu of celiac, superior and inferior mesenteric, and right internal iliac artery occlusion accompanied by a tight stenosis of the left internal iliac artery. Successful stenting of the orifice of the left internal iliac artery was followed by a well-defined dilatation of the meandering artery, revascularization of the peripheral branches of the inferior-through the superior hemorrhoidal artery-and superior mesenteric arteries and complete resolution of the acute mesenteric ischemia. Thus, time was gained for the patient in order to have, if needed, a future elective open revascularization of the mesenteric artery, when the perioperative risk of mortality from the recent myocardial infarction and the coronary angioplasty and stenting will be minimal.

Prognostic significance of EGFR and COX-2 expression in colorectal cancer and their association. A study in Greek population.

PURPOSE: Colon cancer is one of the most common malignancies. Various prognostic markers have been proposed and individualized treatment strategies have been adapted according to tumor molecular and genetic characteristics. The purpose of the present study was to retrospectively analyze a possible association between the expression of COX- 2 and EGFR and clinical and histopathological factors of patients undergoing colon surgery in a Greek population. METHODS: Data from our department's prospectively collected database were retrieved for a total of 100 consecutive colectomies that were performed in our department. We examined patient age, sex, tumor stage and location of the tumor. Histological data were also retrieved concerning major tumor diameter, histological grade and immunohistochemical expression of cyclooxygenase (COX)-2 and epithermal growth factor receptor (EGFR). RESULTS: There was no difference between tumors of different differentiation in the expression of EGFR (p=0.146), while there was statistically significant difference in the expression of COX-2 between these groups (p=0.001). There was no difference between these patients in the expression of EGFR (p=0.136), while a statistically significant difference was found in the expression of COX-2 between the same patient groups (p<0.005). CONCLUSION: These data are quite important in order to certify that colorectal cancer molecular and genetic diversity between different study populations is not a confounding factor in the application and clinical implementation of trending individualized decision making in oncological treatments.

Immunohistochemical expression patterns of S100, synaptophysin, chromogranin A and neuron specific enolase in predicting malignant behaviour in paragangliomas.

PURPOSE: The purpose of this study was to evaluate the role of immunohistochemical markers in the prediction of malignancy in paragangliomas. METHODS: Our institute's patient records between 1990-2012 were retrieved in order to identify patients who were treated for paragangliomas. Size and location of the tumour, existence of concurrent metastatic disease, patient demographics and survival were recorded. Haematoxylin-eosin stained slides were reviewed and all tumours were stained specifically for neuron specific enolase (NSE), chromogranin, synaptophysin and S100 protein positivity. Positivity and expression patterns of the above markers were evaluated and compared between malignant and benign tumours. Malignant behaviour was defined when patient had concurrent or subsequent lymph node involvement, local recurrence and/or metastases. RESULTS: A total of 22 patients with a diagnosis of paraganglioma were treated in our institutes. Female to male ratio was 1.75: 1. The mean age was 43.5 and 51.6 years for women and men, respectively. In 5 patients the tumors had malignant clinical behavior. Their mean size was 3.65 cm for benign and 4.56 cm for malignant neoplasms. NSE expression was diffuse in 47.1% and 0% for benign and malignant tumors, respectively (p=0.10). S100 expression in the periphery of the tumour was typical in 88.2% and 0% for benign and malignant tumors, respectively (p<0.001). CONCLUSION: Immunohistochemical profile from the combination of NSE, synaptophysin chromogranin and S100 staining patterns can serve as a cheap and valuable tool for correctly distinguishing between malignant and benign paragangliomas with high diagnostic accuracy.

Large Paraesophageal Hiatus Hernia: Is Surgery Mandatory?

Purpose/Aim: Paraesophageal hiatus hernias are seldom found, however the incidence is increasing accounting for 5-10% of all hiatal hernias. The aim of this review is to emphasize controversies in clinical presentation, essential workup investigations and highlight non-surgical and surgical management options. Materials and Methods: A PubMed literature search using the keywords "large or giant paraesophageal hernia", "hiatus or hiatal hernia", "laparoscopic surgery", "antireflux surgery", "mesh", "gastric volvulus" and "diaphragmatic hernia" published between 1998 until 2017 was conducted. Results: Presenting symptoms are non-specific and can be erroneously attributed to various more common medical conditions. Significant complications as gastric volvulus and stomach necrosis, may occur and the obscured clinical presentation can be confusing for the clinician. Management options in the elective setting are controversial, and surgical repair cannot be easily justified for a minimally symptomatic condition, especially in an elderly and perhaps frail patient. However, in the era of laparoscopic surgery around the hiatus, reduced operative stress makes surgical repair appealing in the elective setting. Surgical matters as the adjunct of an antireflux procedure or not, the use of prosthetic mesh to reinforce the hiatus, gastropexy and the clinical importance of radiological or endoscopic recurrence are still under debate. Conclusions: The laparoscopic treatment of paraesophageal hiatus hernias is effective with low morbidity rates, offered in symptomatic patients and good operative risk asymptomatic individuals. More studies are needed to assess improvement suggestions, as the use of prosthetic mesh or gastropexy, regarding complications and recurrence risks.

Peritoneal Albumin Dialysis as a Novel Approach for Liver Support: Study in a Porcine Model of Acute Hepatic Failure.

Artificial liver support gained considerable interest in recent years due to the development of various albumin dialysis systems, which prolong survival of some patients with acute liver failure (ALF). Τhis study aims to examine the role of peritoneal albumin dialysis in a postoperative ALF model. ALF was induced in 14 female Landrace pigs by a combination of major liver resection (70-75% of total parenchyma) and ischemic-reperfusion injury on the liver remnant. Animals were randomly divided in two groups (n = 7 each). Both were monitored for 12 h of reperfusion and received peritoneal dialysis for 6 h, beginning 6 h after reperfusion. The albumin group received an albumin-rich solution and the control group received albumin-free solution. The control group gradually developed intracranial hypertension, whereas, in the albumin group, rise in the intracranial pressure was substantially attenuated (P < 0.01, t = 12 h). Albumin-treated animals had significantly lower levels of ammonia (P < 0.01), total bile acids (P < 0.01), free fatty acids (P < 0.05), lactate (P < 0.01), and total bilirubin (P < 0.05). Liver malondialdehyde and protein carbonyl were significantly reduced (P = 0.007 and P = 0.001 at t = 12 h) after albumin dialysis. Results suggest that this method may become a useful adjunct in the management of ALF, thus, justifying further study.

Uncommon benign lesions of the adrenal glands mimicking sinister pathologies: report of 8 cases.

PURPOSE: To present series of patients with large rare primary lesions of the adrenal glands that were operated in our department. The initial indication for surgery was decided based on their impressive similarity to other more sinister adrenal pathologies. METHODS: The clinical records of the department and histopathology reports, covering the 1986-2015 period were assessed. Rare adrenal pathologies that preoperatively were clinically mimicking other adrenal tumors were included. RESULTS: In total, 8 patients (age range 20-75 years) with rare tumors of the adrenal glands were found. Seven patients had a preoperative indication for adrenalectomy due to the possibility of malignancy. In one patient surgery was undertaken due to the possible diagnosis of adrenal hemorrhagic cyst. Among these patients 4 had a histopathologic diagnosis of hemangiomas, one of a lymphangiomatous cyst and 3 of myelolipomas. CONCLUSION: Rare benign tumors of the adrenal glands can present as very large lesions that can be either diagnosed incidentally or due to atypical symptoms. Though unusual, they should be considered in the differential diagnostic approach of adrenal lesions, because they share common clinical and radiological characteristics with more sinister and frequent lesions such as malignant tumors and also hematomas.

The Role of the Glycemic Index and Glycemic Load in the Dietary Approach of Gestational Diabetes Mellitus.

Gestational diabetes mellitus (GDM) is a common metabolic disorder that often develops during pregnancy, characterized by glucose intolerance and insulin resistance (IR). To ensure the well-being of both the mother and the fetus, the body undergoes multiple metabolic and immunological changes that result in peripheral IR and, under certain hereditary or acquired abnormalities, GDM in predisposed women. The adverse short- and long-term effects of GDM impact both the mother and the fetus. Nutrition seems to play an important role to prevent GDM or improve its evolution. An emphasis has been given to the proportion of carbohydrates (CHO) relative to protein and lipids, as well as dietary patterns, in GDM. The effects of CHO on postprandial glucose concentrations are reflected in the glycemic index (GI) and glycemic load (GL). Diets rich in GI and GL may induce or exacerbate IR, whereas diets low in GI and GL appear to enhance insulin sensitivity and improve glycemic control. These positive outcomes may be attributed to direct interactions with insulin and glucose homeostasis or indirect effects through improved body composition and weight management. This comprehensive narrative review aims to explore the significance of nutrition, with a focus on the critical evaluation of GI and GL in the dietary management of women with GDM.

Anesthetic management of a patient with type 1 neurofibromatosis and an occult pheochromocytoma: a case report.

Neurofibromatosis type 1 is a complex genetic disorder affecting multiple organ systems. Cardiovascular manifestations include hypertension, often associated with concomitant pheochromocytoma. We present a hypertensive crisis during induction of anesthesia in a patient with neurofibromatosis type 1, scheduled for abdominal myomectomy, which revealed an undiagnosed pheochromocytoma. The case highlights the importance of assessing all patients with neurofibromatosis type 1 for pheochromocytoma, because if it is left undiagnosed, it can be disastrous in the setting of anesthesia and surgery.

Precision Surgery of Colorectal Liver Metastases in the Current Era: A Systematic Review.

Liver resection for colorectal liver metastases (CRLM) is widely considered the treatment with the highest curative potential. However, not all patients derive the same oncological benefit, underlining the need for better patient stratification and treatment allocation. In this context, we performed a systematic review of the literature to determine the role of RAS status in selecting the optimal surgical strategy. Evidence comparing anatomical with non-anatomical resections depending on RAS mutational status was scarce and conflicting, with two studies reporting superiority in mutated RAS (mutRAS) patients and two studies reporting equivalent outcomes. The rate of incomplete microscopic resection (R1) was found to be increased among mutRAS patients, possibly due to higher micrometastatic spread lateral to the primary lesion. The impact of R1 resection margins was evaluated separately for mutRAS and wild-type patients in three studies, of which, two indicated an additive detriment to long-term survival in the former group. In the current era of precision surgery, RAS status can be utilized to predict the efficacy of liver resection in the treatment of CRLM, avoiding a potentially morbid operation in patients with adverse tumor profiles.

Dietary Approach of Patients with Hormone-Related Cancer Based on the Glycemic Index and Glycemic Load Estimates.

Hormone-related cancers, namely breast, endometrial, cervical, prostate, testicular, and thyroid, constitute a specific group of cancers dependent on hormone levels that play an essential role in cancer growth. In addition to the traditional risk factors, diet seems to be an important environmental factor that partially explains the steadily increased prevalence of this group of cancer. The composition of food, the dietary patterns, the endocrine-disrupting chemicals, and the way of food processing and preparation related to dietary advanced glycation end-product formation are all related to cancer. However, it remains unclear which specific dietary components mediate this relationship. Carbohydrates seem to be a risk factor for cancer in general and hormone-related cancers, in particular, with a difference between simple and complex carbohydrates. Glycemic index and glycemic load estimates reflect the effect of dietary carbohydrates on postprandial glucose concentrations. Several studies have investigated the relationship between the dietary glycemic index and glycemic load estimates with the natural course of cancer and, more specifically, hormone-related cancers. High glycemic index and glycemic load diets are associated with cancer development and worse prognosis, partially explained by the adverse effects on insulin metabolism, causing hyperinsulinemia and insulin resistance, and also by inflammation and oxidative stress induction. Herein, we review the existing data on the effect of diets focusing on the glycemic index and glycemic load estimates on hormone-related cancers.

Changes in Cardiovascular and Renal Biomarkers Associated with SGLT2 Inhibitors Treatment in Patients with Type 2 Diabetes Mellitus.

Type 2 diabetes mellitus is a major health problem worldwide with a steadily increasing prevalence reaching epidemic proportions. The major concern is the increased morbidity and mortality due to diabetic complications. Traditional but also nontraditional risk factors have been proposed to explain the pathogenesis of type 2 diabetes mellitus and its complications. Hyperglycemia has been considered an important risk factor, and the strict glycemic control can have a positive impact on microangiopathy but not macroangiopathy and its related morbidity and mortality. Thus, the therapeutic algorithm has shifted focus from a glucose-centered approach to a strategy that now emphasizes target-organ protection. Sodium-glucose transporter 2 inhibitors is an extremely important class of antidiabetic medications that, in addition to their glucose lowering effect, also exhibit cardio- and renoprotective effects. Various established and novel biomarkers have been described, reflecting kidney and cardiovascular function. In this review, we investigated the changes in established but also novel biomarkers of kidney, heart and vascular function associated with sodium-glucose transporter 2 inhibitors treatment in patients with type 2 diabetes mellitus.

The Protective Effect of Bariatric Surgery on the Development of Colorectal Cancer: A Systematic Review and Meta-Analysis.

BACKGROUND: Obesity is a known risk factor for developing colorectal cancer (CRC) and is associated with the formation of precancerous colonic adenomas. Bariatric surgery (BRS) is considered to reduce the cancer risk in morbidly obese patients. However, the currently available literature yields contradicting results regarding the impact of bariatric surgery on the incidence of CRC. METHODS: A systematic literature search of the Medline, Embase, CENTRAL, CINAHL, Web of Science, and clinicaltrials.gov databases was undertaken following the PRISMA guidelines. A random effects model was selected. RESULTS: Twelve retrospective cohort studies, incorporating a total of 6,279,722 patients, were eligible for inclusion in the final quantitative analysis. Eight studies originated from North America, while four reported on European patients. Patients in the Bariatric Surgery group exhibited a significantly reduced risk for developing colorectal cancer (RR 0.56, 95% CI 0.4-0.8, p < 0.001), while sleeve gastrectomy was found to be significantly associated with a smaller incidence of CRC (RR 0.55, 95% CI 0.36-0.83, p < 0.001), and gastric bypass and banding did not. CONCLUSIONS: A significant protective effect of BRS against the development of CRC is implied. In the present analysis, the incidence rate of colorectal cancer was approximately halved amongst the obese individuals that were operated on.

"Starting from the Image": A Tele-pathology Pre-graduate Course Aimed at Motivating Medical Students.

In the tele-course entitled "Starting from the image", medical students are confronted with practical tasks in relevant professional contexts. Initially, a macroscopic or microscopic image of a patient case is presented to learners who then receive relevant information on the patient's history, clinical findings, and other laboratory tests. A pathologist actively discusses the pathological findings; then, a clinician explains their implications for the patient's individualized treatment and prognosis. In this way, pathology's interaction with other medical specialties is highlighted. Students declared that through these simulated professional practice experiences, they strengthened their decision-making skills. Educators should consider upgrading from information-based teaching to practice-focused instruction.

Small liver remnants are more vulnerable to ischemia/reperfusion injury after extended hepatectomies: a case-control study.

BACKGROUND: There is evidence that small-for-size liver grafts are more vulnerable to ischemia/reperfusion injury after liver transplantation. We hypothesized that ischemic injury is more pronounced in small liver remnants after major hepatectomies. METHODS: Fifteen patients underwent extended hepatectomy with remnant liver mass less than 30% of standard liver weight (study group). These patients were matched with patients who underwent minor liver resection, with liver remnants equal to or more than 70% of standard liver weight (control group). Ischemia/reperfusion injury was assessed by tissue caspase-3 activity postoperatively as well as peak aspartate aminotransferase (AST) values and a-glutathione S-transferase (α-GST) levels adjusted for remnant liver weight. In addition, caspase-3 activity and adjusted serum markers of hepatocyte injury were correlated with the degree of postoperative portal hypertension. RESULTS: Caspase-3 activity was higher in patients with small liver remnants (22.66±6.57 vs. 12.60±4.06 count per high-power field, p<0.001). Serum markers of hepatocyte injury, when adjusted per gram of liver remnant, were found to be higher in the study group than in the control group (AST: 1.26±0.25 vs. 0.54±0.11 IU g(-1), p<0.001; α-GST: 0.14±0.02 vs. 0.08±0.01 IU g(-1), p<0.001). Tissue caspase-3 expression in the small liver remnant group correlated with both AST and α-GST levels adjusted per gram of liver remnant (r2=0.51, p=0.005 and r2=0.71, p<0.001, respectively). Significant correlations between postoperative portal hypertension and the same markers as well as caspase-3 activity were also demonstrated. CONCLUSION: Liver remnants less than 30% of standard liver weight are much more susceptible to ischemia/reperfusion injury than controls twice the size. Adjustment of serum markers of hepatocyte injury to the liver remnant weight depicts injury more accurately.

Pancreatic injury after major hepatectomy: a study in a porcine model.

PURPOSE: The aim of this study was to investigate the pathophysiology of pancreatitis after major hepatectomy. METHODS: The study used ten female pigs. Three served as sham animals (sham group) and were killed after laparotomy to obtain normal tissue samples. Seven animals were subjected to major hepatectomy (70-75%), using the Pringle maneuver for 150 min, after constructing a portacaval side-to-side anastomosis (hepatectomy group). Duration of reperfusion was 24 h. RESULTS: Pancreatic tissue sampled 24 h after reperfusion had increased necrosis and edema in comparison to sham group and to tissue sampled at 12 h. Tissue malondialdehyde (MDA) did not differ significantly between samples at 12 and 24 h but was increased in the hepatectomy group in comparison to sham animals. Percentage increase in portal MDA content during reperfusion was greater at 12 h of reperfusion in comparison to the increase after 24 h. Portal pressure increased significantly after 12 h of reperfusion. Serum amylase and C-peptide increased during reperfusion in comparison to baseline levels. CONCLUSIONS: The findings suggest that intraoperative portal congestion is not the only cause of the development of pancreatitis after major hepatectomy. The oxidative markers suggest that reactive oxygen species produced during vascular control may be responsible as well.

Synchronous Sternal Metastasectomy and Total Thyroidectomy for Differentiated Thyroid Cancer: A Rare Case Report.

Bone metastases from thyroid cancer are mainly rare, while sternal metastases are extremely uncommon. Bone metastases might be either synchronous or metachronous to primary thyroid cancer. A 60-year-old male patient presented to our department with a painful, fixed and firm sternal mass. Preoperative imaging studies, such as neck ultrasound (US) and computed tomography (CT) of the chest, revealed a 6.5 cm nodule of the right thyroid lobe with high-risk malignancy characteristics and a massive metastatic mass of the anterior mediastinal, which was extended from the sternal notch to the third intercostal space. The diagnosis of papillary thyroid carcinoma with sternal metastatic lesions was established. After meticulous discussion in the multidisciplinary board of our hospital, a total thyroidectomy plus en-bloc resection of this massive sternal metastasis and adjuvant radioiodine therapy were decided. Eight months postoperatively, no recurrence has occurred in this patient. R0 resection of isolated bone metastasis of thyroid origin is still an optimal therapeutic decision for these patients. In cases of sternal metastasis, radical surgical resection with negative margins, including both resection of the lesion and reconstruction of the chest wall, in order to successfully maintain the chest wall's stability, is recommended.
