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.

Meta-Analysis
Hypercalcaemia of malignancy (HCM) is a common metabolic complication of advanced malignancies with a prevalence varying from 2-30%, depending on cancer type and disease stage. HCM is associated with impaired quality of life, increased risk of hospitalisation and limited survival. Evidence-based guidelines for management of HCM have been lacking to date, despite its prevalence and detrimental impact. This concise guidance highlights key recommendations from the recent Endocrine Society Clinical Practice Guidelines on Treatment of Hypercalcaemia of Malignancy in Adults, published in December 2022. A systematic review and meta-analysis was commissioned to support the guideline development process. Key suggestions include the use of denosumab in preference to intravenous bisphosphonates as first-line treatment for HCM and the use of denosumab in cases of recurrent or refractory HCM in patients previously treated with intravenous bisphosphonates. The guideline also identifies priority areas for future research.

Review
OBJECTIVE
Parathyroid carcinoma is rarely encountered in clinical practice. When faced with this clinical challenge, there is currently a paucity of evidence available for the optimal management of patients with parathyroid carcinoma. This systematic review synthesizes the available literature to evaluate the optimal management approach, thus providing guidance for future management.
METHODS
A systematic review was conducted according to PRISMA guidelines using Ovid MEDLINE, EMBASE, and PubMed databases for studies, published in English, reporting on parathyroid carcinoma. Full text of potentially eligible articles were reviewed by two authors independently and eligible studies selected. Treatment options and associated outcomes were evaluated. Descriptive statistics were used to describe pooled patient cohorts.
RESULTS
3203 articles were initially identified using the search criteria with 59 full-text articles then screened for eligibility. Seven articles, all retrospective studies, concerning 2307 patients (median 224/study). Parathyroidectomy alone was the most frequently utilised surgical approach across all studies, followed by en-bloc resection (with adjacent thyroid and/or nodal tissue). There was no difference in post-operative morbidity, mortality or survival between surgical approaches (p < 0.005). Patients who underwent either form of surgery had longer overall survival than those managed non-operatively (p < 0.005).
CONCLUSION
Surgical resection is the optimal treatment of parathyroid carcinoma. However there remains no consensus on the optimal extent of surgery, and as such future randomised prospective studies are necessary to evaluate the effects of different surgical approaches on morbidity, mortality and oncologic outcomes. Following resection, long-term surveillance with PTH is advised.

Meta-Analysis
BACKGROUND
The incidence and risk factors of acute kidney injury (AKI) in patients with malignancies receiving immune checkpoint inhibitors (ICIs) are being extensively reported with their widespread application.
OBJECTIVE
This study aimed to quantify the incidence and identify risk factors of AKI in cancer patients treated with ICIs.
METHODS
We searched the electronic databases of PubMed/Medline, Web of Science, Cochrane and Embase before 1 February 2023 on the incidence and risk factors of AKI in patients receiving ICIs and registered the protocol in PROSPERO (CRD42023391939). A random-effect meta-analysis was performed to quantify the pooled incidence estimate of AKI, identify risk factors with pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) and investigate the median latency period of ICI-AKI in patients treated with ICIs. Assessment of study quality, meta-regression, and sensitivity and publication bias analyses were conducted.
RESULTS
In total, 27 studies consisting of 24048 participants were included in this systematic review and meta-analysis. The overall pooled incidence of AKI secondary to ICIs was 5.7% (95% CI: 3.7%-8.2%). Significant risk factors were older age (OR: 1.01, 95% CI: 1.00-1.03), preexisting chronic kidney disease (CKD) (OR: 2.90, 95% CI: 1.65-5.11), ipilimumab (OR: 2.66, 95% CI: 1.42-4.98), combination of ICIs (OR: 2.45, 95% CI: 1.40-4.31), extrarenal immune-related adverse events (irAEs) (OR: 2.34, 95% CI: 1.53-3.59), and proton pump inhibitor (PPI) (OR: 2.23, 95% CI: 1.88-2.64), nonsteroidal anti-inflammatory drug (NSAID) (OR: 2.61, 95% CI: 1.90-3.57), fluindione (OR: 6.48, 95% CI: 2.72-15.46), diuretic (OR: 1.78, 95% CI: 1.32-2.40) and angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin-receptor blockers (ARBs) (pooled OR: 1.76, 95% CI: 1.15-2.68) use. Median time from ICIs initiation to AKI was 108.07 days. Sensitivity and publication bias analyses indicated robust results for this study.
CONCLUSION
The occurrence of AKI following ICIs was not uncommon, with an incidence of 5.7% and a median time interval of 108.07 days after ICIs initiation. Older age, preexisting chronic kidney disease (CKD), ipilimumab, combined use of ICIs, extrarenal irAEs, and PPI, NSAID, fluindione, diuretics and ACEI/ARB use are risk factors for AKI in patients receiving ICIs.

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.

OBJECTIVE
Primary hyperparathyroidism is a common disorder of the parathyroid glands. Parathyroid adenoma (PA) in pregnancy is a relatively rare disease, whose diagnosis and treatment is a challenging task. The aim of the present study is to present a new case of parathyroid adenoma during pregnancy and to give a detailed account of all reported cases of parathyroid adenoma during pregnancy in the literature.
STUDY DESIGN
A bibliographic research was performed, and characteristics of parathyroid adenomas in pregnancy such as age, gestational week at diagnosis, ionized calcium levels, genetic testing result, symptomatology, radiological method of localization, treatment method, gestational week at operation, and maternal/fetal complications were recorded.
RESULTS
A 34-year-old woman at her 25 weeks' gestation was diagnosed with parathyroid adenoma and was referred to our Surgical Department due to contraindication for conservative treatment. A parathyroidectomy was performed, and the maternal and fetal postoperative period was uneventful. Two hundred eleven cases of parathyroid adenoma in pregnancy were recorded in the literature, and statistical analysis was performed. The median gestational week at diagnosis was 21 ± 9.61 weeks. The mean level of ionized calcium was 2.69 mmol/l [SD = 0.75 (2.55-2.84 95% CI)]. Most cases were familiar (72.4%), while surgery was the preferred treatment option (67.3%). The majority of cases were asymptomatic (21.7%), and the main radiological method applied for localization was ultrasound (63.4%).
CONCLUSION
Parathyroid adenoma in pregnancy is a rare condition. The early diagnosis is of great importance as surgical treatment at the second trimester of pregnancy outweighs the maternal and fetal risks.

Meta-Analysis
BACKGROUND
There is a growing concern with inappropriate, excessive perioperative blood transfusions. Understanding the influence of low preoperative hemoglobin (Hgb) on perioperative blood transfusion (PBT) in head and neck cancer (HNC) surgery with free flap reconstruction may help guide clinical practice to reduce inappropriate treatment among these patients. The objective is to synthesize evidence regarding the association between preoperative Hgb and PBT among major HNC free flap surgeries.
METHODS
Terms and synonyms for HNC surgical procedures, Hgb and PBT were used to search MEDLINE, Embase, CINAHL, Cochrane Central Register of Controlled Trials and Cochrane Database of Reviews from inception to February 2020. Reference lists of included full texts and studies reporting the preoperative Hgb, anemia or hematocrit (exposure) and the PBT (outcome) in major HNC surgery with free flap reconstruction were eligible. Studies examining esophageal, thyroid and parathyroid neoplasms were excluded; as were case reports, case series (n < 20), editorials, reviews, perspectives, viewpoints and responses. Two independent, blinded reviewers screened titles, abstracts and full texts in duplicate. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses was followed. A random-effects model was used to pool reported data. The primary outcome was the proportion of patients who had a PBT. Subgroup analysis examined sources of heterogeneity for perioperative predictors of PBT (age, sex, flap type, flap site and preoperative Hgb). We also examined mean preoperative Hgb in the PBT and no PBT groups.
RESULTS
Patients with low preoperative Hgb were transfused more than those with normal Hgb (47.62%, 95% CI = 41.19-54.06, I = 0.00% and 13.92%, 95% CI = 10.19-17.65, I = 20.69%, respectively). None of the predictor variables explained PBT. The overall pooled mean preoperative Hgb was 12.96 g/dL (95% CI = 11.33-14.59, I = 0.00%) and was 13.58 g/dL (95% CI = 11.95-15.21, I = 0.00%) in the no PBT group and 12.05 g/dL (95% CI = 10.01 to 14.09, I = 0.00%) in the PBT group.
CONCLUSIONS
The heterogeneity between studies, especially around the trigger for PBT, highlights the need for additional research to guide clinical practice of preoperative Hgb related to PBT to enhance patient outcomes and improve healthcare stewardship.

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
PURPOSE
Ultrasound (US) is the first choice in the detection of thyroid nodules in pediatric and adult patients. The purpose of this study was to evaluate the diagnostic performance of adult-based US risk stratification systems (RSSs) when applied to the pediatric population.
METHODS
Medline, Embase, and Cochrane Library (CENTRAL) were searched up to 5 March 2023 for studies about the diagnostic performance of adult-based US RSS in pediatric patients. The pooled sensitivity, specificity, positive likelihood ratio (LR), negative LR, and diagnostic odds ratio (DOR) were calculated. The summary receiver operating characteristic (SROC) curves and area under the curve (AUC) were also analyzed.
RESULTS
The sensitivity was highest in American College of Radiology-Thyroid Imaging Reporting and Data System (ACR-TIRADS) category 4-5 and American Thyroid Association RSS high-intermediate risk (ATA), which was 0.84 [0.79, 0.88] and 0.84 [0.75, 0.90], respectively. The specificity was highest in ACR-TIRADS category 5 and Europe-TIRADS (EU-TIRADS) category 5, which was 0.93 [0.83, 0.97] and 0.93 [0.88, 0.98], respectively. The ACR-TIRADS, ATA, and EU-TIRADS showed moderate diagnostic performance in pediatric thyroid nodule patients. For Korea-TIRADS (K-TRADS) category 5, the summary sensitivity and specificity with a 95% CI were 0.64 [0.40, 0.83] and 0.84 [0.38, 0.99], respectively.
CONCLUSIONS
In conclusion, the ACR-TIRADS, ATA, and EU-TIRADS have moderate diagnostic performance in pediatric thyroid nodule patients. The diagnostic efficacy of the K-TIRADS was not as high as expected. However, the diagnostic performance of Kwak-TIRADS was uncertain because of the small sample size and small number of studies included. More studies are needed to evaluate these adult-based RSSs in pediatric patients with thyroid nodules. RSSs specific for pediatric thyroid nodules and thyroid malignancies were necessary.

Meta-Analysis
BACKGROUND
Emerging remote-access surgical methods are utilized to treat differentiated thyroid cancer. The study aimed to compare the surgical integrity, safety, efficacy, and postoperative experience of patients among common surgical methods.
METHODS
The PubMed, Medline, Cochrane Library, Web of Science, and EMBASE databases were searched from their inception until March 2023. Pairwise meta-analysis and Bayesian network meta-analysis were performed. The surface under the cumulative ranking curve (SUCRA) was used to illuminate the probability that each method would be the best for each outcome.
RESULTS
Thirty-two studies comprising 7042 patients were included. Robotic bilateral axillo-breast approach (RBABA) and robotic gasless transaxillary approach (RGAA) retrieved fewer lymph nodes (LNs) than open thyroidectomy (OT). RBABA showed a significantly lower permanent recurrent laryngeal nerve (RLN) palsy rate than OT. According to SUCRA values, endoscopic transoral approach (EOA) ranked the highest in retrieved LNs (0.84), the proportion of stimulated serum thyroglobulin less than 1.0 ng/ml (0.77), and the pain score (0.77). Endoscopic bilateral areola approach (EBAA) ranked the highest in the transient RLN palsy rate (0.72). The endoscopic gasless transaxillary approach (EGAA) ranked the highest in the transient hypoparathyroidism rate (0.78). RBABA ranked the highest in the rate of permanent RLN palsy (0.94) and hypoparathyroidism (0.77). OT ranked the highest in operative time (0.92).
CONCLUSIONS
Each surgical method of total thyroidectomy has benefits and limitations. EOA performed the best in maintaining surgical integrality and reducing the pain score, while taking a long operative time. Generally, RBABA showed the best advantage in protecting parathyroid glands and RLN but with the longest operative time. OT had the best advantage in operative time. Therefore, OT and EOA are ideal methods for patients with a higher risk of central LN metastasis. RBABA and EOA may not be suitable for elderly patients or those with high anesthesia risk.
