Review
BACKGROUND
Neuroendocrine neoplasms (NEN) originate from neuroendocrine cells ubiquitously spread throughout the body. Hypercalcemia associated with cancer is the most common life-threatening metabolic disorder in patients with advanced stage cancer. Paraneoplastic hypercalcemia is more commonly associated with hematological malignancies, renal and breast carcinomas, and squamous cell carcinomas, but it has also been described in patients with well-differentiated NEN, where it often remains undiagnosed. Among its causes, systemic secretion of parathyroid hormone-related protein (PTHrP) and ectopic production of 1,25-dihydroxyvitamin D and parathyroid hormone (PTH) may be considered paraneoplastic causes of hypercalcemia. In order to clarify the diagnostic work up of paraneoplastic hypercalcemia in patients with NEN, we perform a systematic review, which is lacking in the literature.
METHODS
We performed a data search using MEDLINE and SCOPUS including papers from 1961 to 2021. We selected articles on paraneoplastic hypercalcemia associated with well-differentiated NEN.
RESULTS
The search led to the selection of 78 publications for a total of 114 patients. Pooled data showed that the most frequent primary tumor site associated with paraneoplastic hypercalcemia was pancreatic NEN, followed by Pheochromocytoma. In most cases, paraneoplastic hypercalcemia was caused by PTHrP production and secretion. In more than two thirds of cases, paraneoplastic hypercalcemia was present at the time of NEN diagnosis and, in metachronous cases, was related to local recurrence, distant metastasis development, or tumor progression. In most patients, a combination of therapeutic approaches was employed, and reduction of the tumor burden was essential to control the paraneoplastic syndrome.
DISCUSSION
The onset of hypercalcemia associated with cancer in patients with well-differentiated NEN represents a major clinical challenge. The complex clinical and therapeutical management of paraneoplastic hypercalcemia implies the need for a multidisciplinary approach, aimed at controlling the clinical syndrome and tumor growth.

Meta-Analysis
BACKGROUND
The increasing burden of non-alcoholic fatty liver disease (NAFLD) worldwide imposes an emerging public health issue. We perform the current study to estimate the global prevalence, incidence, disease progression, and clinical outcomes of NAFLD.
METHODS
A systematic search was conducted in Medline, Embase, Web of Science, Google Scholar, and Cochrane CENTRAL that screened articles in English language published from January 2000 to December 2021. NAFLD prevalence, incidence, rate of disease progression, and outcomes were calculated with the DerSimonian-Laird random effects model with arcsine transformation.
RESULTS
Our search identified 59,156 records, of which 578 studies fulfilled our inclusion criteria. The overall prevalence of NAFLD was 29.38% (95% confidence interval [CI] 28.09-30.69) regardless of the diagnostic techniques. Looking at the group in which the diagnosis was made by ultrasound exclusively, the pooled prevalence was 30.49% (95% CI 29.55-31.43). NAFLD has become more prevalent during the year 2011-2021 (31.63%, 95% CI 30.23-33.04) compared with year 2000-2010 (27.94%, 95% CI 26.23-29.69). The pooled estimation of non-alcoholic steatohepatitis prevalence was 8.26% (95% CI 1.13-21.01), 46.49% (95% CI 35.93-57.20), and 46.72% (95% CI 37.57-55.98) in general population, NAFLD patients, and severe/morbidly obese patients, respectively. Based on a total of 110,142 newly developed NAFLD patients, the pooled incident rate was estimated as 46.24 cases per 1000 person-years (95% CI 43.21-49.30). In patients with NAFLD, the incident rate of hepatocellular carcinoma was 1.46 (95% CI 0.90-2.03) cases per 1000 person-years. The overall pooled estimate of NAFLD related mortality was 23.91 (95% CI 13.55-37.18) death per 1000 person-years.
CONCLUSIONS
The prevalence of NAFLD is increasing globally. It is contributing to poor clinical outcomes including hepatocellular carcinoma and death. Rising awareness and urgent actions are warranted to control the NAFLD pandemic across the globe.

Meta-Analysis
BACKGROUND
One-step nucleic acid amplification (OSNA) analysis is a molecular diagnostic technique for lymph node metastases (LNMs) by quantifying cytokeratin 19(CK 19) mRNA. We aim to evaluate the intraoperative diagnostic accuracy of OSNA assay for LNMs of papillary thyroid carcinoma (PTC).
METHODS
PubMed, Embase, Cochrane Library, and Web of Science databases were searched to retrieve related literature. A meta-analysis was performed using STATA11.0, Meta-Disc 1.4 and RevMan 5.3.
RESULTS
This meta-analysis included six studies involving 987 lymph nodes from 194 patients. The pooled sensitivity, specificity, and area under the summary receiver-operating characteristic curve (AUC) of OSNA for detecting LNM were 0.88, 0.90, and 0.95, respectively.
CONCLUSION
OSNA assay is an accurate molecular diagnosis for intraoperative detection of lymph node metastasis in PTC.

BACKGROUND
Parathyroid carcinoma (PC) is a rare malignancy, the incidence of which is less than 1/1 million per year. Sarcomatoid parathyroid carcinoma (SaPC) is an extremely peculiar subtype; only three cases have been reported internationally. It consists of both malignant epithelial components and sarcomatoid components (mesenchymal origin) simultaneously. This "confusing" cancer exhibits higher invasiveness, and traditional surgery does not appear to achieve the expectation, which differs significantly from that of general PC.
OBJECTIVE
To characterize the clinicopathologic features of SaPC and explore similarities and differences between SaPC and general PC.
MATERIALS AND METHODS
We collected clinical data of SaPC cases from our center and literature. The SaPC case in our center was presented. To better understand the characteristics of SaPC, we also reviewed clinical information in general PC cases from our center and literature within the last 5 years, and a systematic review was performed for further comparison.
RESULTS
A 60-year-old woman was admitted for a neck mass and hoarseness. After the surgery, she was confirmed as SaPC and ultimately developed local recurrence at 3 months. Together with the reported cases from literature, four cases of SaPC (three cases from literature) and 203 cases of general PC (200 cases from literature) were reviewed. Both tumors showed obvious abnormalities in parathormone (PTH) level and gland size. Compared to general PC, SaPC has a later age of onset (60.50 ± 7.42 vs. 51.50 ± 8.29), relatively low levels of PTH (110.28 ± 59.32 vs. 1,156.07 ± 858.18), and a larger tumor size (6.00 ± 1.63 vs. 3.14 ± 0.70). For SaPC, all four cases were initially misdiagnosed as thyroid tumors (4/4). Spindle cell areas or transitional zones were common pathological features in SaPC cases (3/4).
CONCLUSION
SaPC is a very rare pathologic subtype of PC and appears to be much more easily misdiagnosed as a thyroid tumor. Spindle cell areas or transitional zones are highly possible to be pathological features in its sarcomatoid components. Despite many similarities, there are some differences between SaPC and general PC-SaPC does not show the obvious endocrine feature but stronger aggressiveness. Surgical treatment of SaPC does relieve life-threatening symptoms and improve quality of life even with recurrence in the short term.

Meta-Analysis
OBJECTIVE
We aim to assess the accuracy of near infrared autofluorescence in identifying parathyroid gland during thyroid and parathyroid surgery.
METHOD
A systematic literature search was conducted by using PubMed, Embase, and the Cochrane Library electronic databases for studies that were published up to February 2021. The reference lists of the retrieved articles were also reviewed. Two authors independently assessed the methodological quality and extracted the data. A random-effects model was used to calculate the combined variable. Publication bias in these studies was evaluated with the Deeks' funnel plots.
RESULT
A total of 24 studies involving 2,062 patients and 6,680 specimens were included for the meta-analysis. The overall combined sensitivity and specificity, and the area under curve of near infrared autofluorescence were 0.96, 0.96, and 0.99, respectively. Significant heterogeneities were presented (Sen: I = 87.97%, Spe: I = 65.38%). In the subgroup of thyroid surgery, the combined sensitivity and specificity, and the area under curve of near infrared autofluorescence was 0.98, 0.99, and 0.99, respectively, and the heterogeneities were moderate (Sen: I = 59.71%, Spe: I = 67.65%).
CONCLUSION
Near infrared autofluorescence is an excellent indicator for identifying parathyroid gland during thyroid and parathyroid surgery.

Meta-Analysis
BACKGROUND
The aim of the study was to assess the feasibility, safety, and potential benefits of four approaches of robotic assisted thyroidectomy (RT). The approaches mentioned above are also compared with traditional open thyroidectomy (OPEN).
MATERIALS AND METHODS
Medline, Embase, Cochrane library (CENTRAL) and Web of Science databases were searched up to 13th Dec 2019. Data of surgical outcomes and complications were extracted to conduct the statistical analyses.
RESULTS
A total of 30 studies with 6622 patients were included. Ten were prospective study and 1 declared prospective randomized comparative study. The number of retrieved lymph nodes (LNs) in central compartment were similar between gasless transaxillary approach (GAA), bilateral axillo-breast approach (BABA) and transoral approach (OA). OPEN retrieved more LNs than BABA and OA. More metastatic LNs were seen in GAA and BABA than OA, as was for OPEN. The operation time was significantly shorter in GAA and gasless unilateral transaxillary approach (GUAA) than BABA and OA, while shortest for OPEN. Lower incidence of transient hypoparathyroidism was found in BABA than OPEN. No significant difference was observed in other indexes.
CONCLUSIONS
BABA, GAA, GUAA and OA in RT appear to be feasible and safe for patients with thyroid cancer with unique benefits. Surgical outcomes of different approaches were not identical for operation time, cosmetic effects, central neck dissection. Surgeons would consider more about patients' will.

Anaplastic thyroid cancer (ATC) is a rare but highly lethal form of thyroid cancer. Since the guidelines for the management of ATC by the American Thyroid Association were first published in 2012, significant clinical and scientific advances have occurred in the field. The aim of these guidelines is to inform clinicians, patients, and researchers on published evidence relating to the diagnosis and management of ATC. The specific clinical questions and topics addressed in these guidelines were based on prior versions of the guidelines, stakeholder input, and input of the Task Force members (authors of the guideline). Relevant literature was reviewed, including serial PubMed searches supplemented with additional articles. The American College of Physicians Guideline Grading System was used for critical appraisal of evidence and grading strength of recommendations. The guidelines include the diagnosis, initial evaluation, establishment of treatment goals, approaches to locoregional disease (surgery, radiotherapy, targeted/systemic therapy, supportive care during active therapy), approaches to advanced/metastatic disease, palliative care options, surveillance and long-term monitoring, and ethical issues, including end of life. The guidelines include 31 recommendations and 16 good practice statements. We have developed evidence-based recommendations to inform clinical decision-making in the management of ATC. While all care must be individualized, such recommendations provide, in our opinion, optimal care paradigms for patients with ATC.

Comparative Study Meta-Analysis
OBJECTIVE
The purpose of this study was to evaluate the efficacy of different nucleos(t)ide analogues in the prognosis of HBV-related hepatocellular carcinoma (HCC) patients after curative treatment by network meta-analysis.
METHODS
Literature retrieval was conducted in globally recognized databases, namely, PubMed, EMBASE, Cochrane Library databases, and Science Citation Index Expanded, to address relative studies investigating nucleot(s)ide analogues for HBV-related HCC patients after curative resection. Relative parametric data, including 1-, 3-, and 5-year overall survival rate and 1-, 3-, and 5-year recurrence-free survival rate were quantitatively pooled and estimated. The inconsistency factor, the cumulative ranking curve, and the publication bias were evaluated.
RESULTS
Fourteen observational studies of 2481 adults performed between 2000 and 2019 were eligible. In terms of overall survival, ADV (Adefovir dipivoxil) (Odds ratio (OR): 2.35, 95% confidence interval (CI): 1.17-4.73), Lamivudine (OR: 2.08, 95% CI: 1.78-5.58), and Entecavir (OR: 2.14, 95% CI: 1.59-2.88) were found to be more beneficial than control group while ADV has the highest probability of having the most efficacious treatment (SCURA values 66.3) for 5-year overall survival. In late recurrence-free survival, ADV (OR = 1.88, 95% CI: 1.77-4.60), Entecavir (OR = 1.96, 95% CI: 1.36-2.55), and Lamivudine (OR = 1.73, 95% CI: 1.06-2.82) all had better significant prognosis than patients without antiviral therapy postoperatively and patients with ADV as postoperative antiviral therapy has significantly recurrence-free survival benefit at 5-year follow-up compared to those undertaking Entecavir (OR = 1.96, 95% CI: 1.52-7.38) and Lamivudine (OR = 1.39, 95% CI: 1.09-3.01). Moreover, the application of ADV possessed the highest possibility of having the best clinical effects on 1- (surface under the cumulative ranking probabilities (SUCRA), 64.7), 3- (SUCRA, 64.7), and 5-year (SUCRA, 70.4) recurrence survival rate for HBV-related HCC patients.
CONCLUSIONS
Patients with postoperative nucleos(t)ide analogues antiviral therapy had better survival benefit than those without antiviral therapy for HBV-related HCC patients after curative treatment. Additionally, nucleotide analogues like ADV and Tenofovir disoproxil fumarate has better impact on early and late recurrence-free survival of patients after curative treatment than those undertaking nucleoside analogues.

Meta-Analysis
BACKGROUND
The association between telomerase reverse transcriptase (TERT) promoter mutations and some clinical behaviors in thyroid cancer remains controversial and requires additional investigation. This study aimed to evaluate the association between TERT promoter mutations and clinical behaviors (including clinicopathological features and prognosis) in differentiated thyroid carcinomas (DTC).
METHODS
We performed an up-to-date systematic review and current comprehensive meta-analysis. We searched three electronic databases for relevant studies. We used fixed- or random-effect models to calculate pooled estimated odds ratios (ORs) or standardized mean differences (SMDs) and corresponding 95% confidence intervals (CIs).
RESULTS
We included 51 eligible studies incorporating 11,382 cases. Average frequencies of TERT promoter mutations in DTC, papillary (PTC), and follicular (FTC) thyroid carcinomas were 10.9%, 10.6%, and 15.1%, respectively. In DTC and PTC, TERT promoter mutations were significantly associated with sex, age, tumor size, vascular invasion, extrathyroidal extension, lymph node and distant metastases, advanced tumor, nodes, and metastasis (TNM) stage, persistence/recurrence, and disease-specific mortality. In FTC, TERT promoter mutations were significantly associated with age, distant metastases, advanced TNM stage, persistence/recurrence, and disease-specific mortality.
CONCLUSIONS
TERT promoter mutations could be considered as biomarkers assisting in risk stratification, prognostic prediction, and individualizing therapeutic options for DTC (PTC and FTC).
