Review
BACKGROUND
Over the past ten years, the incidence rate of papillary thyroid carcinoma (PTC) worldwide has been increasing rapidly year by year, with the incidence rate increasing 6% annually. PTC has become the malignant tumor with the highest growth rate in the world that fourteen PTC-related mutant genes have been identified. Whether the BRAF mutation related to more aggressive clinicopathologic features and worse outcome in PTC remains variable and controversial. We aim to investigate the risk factors that may predict the BRAF mutation potential of these lesions and new prevention strategies in PTC patients.
METHODS
A total of 9,908 papillary thyroid carcinoma patients with average 74.6% BRAF mutations were analyzed (RevMan 5.3 software) in this study. The PubMed, Embase, and ISI Web of Science databases were systematically searched for works published through December 15, 2021.
RESULTS
The following variables were associated with an increased risk of BRAF mutation in PTC patients: age ≥ 45 years (OR = 1.39, 95%CI = 1.21-1.60, < 0.00001), male gender (OR = 1.13, 95%CI = 0.99-1.28, = 0.06), multifocality (OR = 1.22, 95%CI = 1.07-1.40, = 0.004), lymph node metastasis (OR = 1.33, 95%CI = 0.79-2.23, = 0.28), extrathyroidal extension + (OR = 1.61, 95%CI = 1.06-2.44, = 0.03), vascular invasion + (OR = 2.04, 95%CI = 1.32-3.15, = 0.001), and tumor node metastasis stage (OR = 1.61, 95%CI = 1.38-1.88, < 0.00001). In addition, tumor size (>1 cm) (OR = 0.51, 95%CI = 0.32-0.81, = 0.005) and distant metastasis (OR = 0.69, 95%CI = 0.22-2.21, = 0.54) had no association or risk with BRAF mutation in PTC patients.
CONCLUSION
Our systematic review identified the following significant risk factors of BRAF mutation in PTC patients: age (≥45 years), gender (male), multifocality, lymph node metastasis, vascular invasion, extrathyroidal extension, and advanced tumor node metastasis stage (stages III and IV). Tumor size (>1 cm) and distant metastasis do not appear to be correlated with BRAF mutation in PTC patients.

Review
Osteoarthritis (OA) is a multifactorial chronic disease primarily characterized by the degeneration of articular cartilage. Currently, there is a lack of effective treatments for OA other than surgery. The exploration of the mechanisms of occurrence is important in exploring other new and effective treatments for OA. The current evidence shows that the Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway plays a vital role in cytogenesis and is involved in OA progression. The terms "JAK2", "STAT3", and "Osteoarthritis"were used in a comprehensive literature search in PubMed to further investigate the relationship between the JAK2/STAT3 signaling pathway and OA. This review focuses on the role and mechanism of JAK2/STAT3 signaling in cartilage degradation, subchondral bone dysfunction, and synovial inflammation. In addition, this review summarizes recent evidence of therapeutic approaches to treat OA by targeting the JAK2/STAT3 pathway to accelerate the translation of evidence into the progression of strategies for OA treatment.

PURPOSE
Polycystic ovary syndrome (PCOS) is a complex genetic trait and the most common endocrine disorder of women, clinically evident in 5% to 15% of reproductive-aged women globally, with associated cardiometabolic dysfunction. Adipose tissue (AT) dysfunction appears to play an important role in the pathophysiology of PCOS even in patients who do not have excess adiposity.
METHODS
We undertook a systematic review concerning AT dysfunction in PCOS, and prioritized studies that assessed AT function directly. We also explored therapies that targeted AT dysfunction for the treatment of PCOS.
RESULTS
Various mechanisms of AT dysfunction in PCOS were identified including dysregulation in storage capacity, hypoxia, and hyperplasia; impaired adipogenesis; impaired insulin signaling and glucose transport; dysregulated lipolysis and nonesterified free fatty acids (NEFAs) kinetics; adipokine and cytokine dysregulation and subacute inflammation; epigenetic dysregulation; and mitochondrial dysfunction and endoplasmic reticulum and oxidative stress. Decreased glucose transporter-4 expression and content in adipocytes, leading to decreased insulin-mediated glucose transport in AT, was a consistent abnormality despite no alterations in insulin binding or in IRS/PI3K/Akt signaling. Adiponectin secretion in response to cytokines/chemokines is affected in PCOS compared to controls. Interestingly, epigenetic modulation via DNA methylation and microRNA regulation appears to be important mechanisms underlying AT dysfunction in PCOS.
CONCLUSION
AT dysfunction, more than AT distribution and excess adiposity, contributes to the metabolic and inflammation abnormalities of PCOS. Nonetheless, many studies provided contradictory, unclear, or limited data, highlighting the urgent need for additional research in this important field.

Meta-Analysis
BACKGROUND
HER2-positive (HER2+) breast cancer (BC) comprises all the four PAM50 molecular subtypes. Among these, the HER2-Enriched (HER2-E) appear to be associated with higher pathological complete response (pCR) rates following anti-HER2-based regimens. Here, we present a meta-analysis to validate the association of the HER2-E subtype with pCR following anti-HER2-based neoadjuvant treatments with or without chemotherapy (CT).
METHODS
A systematic literature search was performed in February 2019. The primary objective was to compare the association between HER2-E subtype (versus others) and pCR. Selected secondary objectives were to compare the association between 1) HER2-E subtype and pCR in CT-free studies, 2) HER2-E subtype within hormone receptor (HR)-negative and HR+ disease and 3) HR-negative disease (versus HR+) and pCR in all patients and within HER2-E subtype. A random-effect model was applied. The Higgins' I was used to quantify heterogeneity.
RESULTS
Sixteen studies were included, 5 of which tested CT-free regimens. HER2-E subtype was significantly associated with pCR in all patients (odds ratio [OR] = 3.50, p < 0.001, I = 33%), in HR+ (OR = 3.61, p < 0.001, I = 1%) and HR-negative tumors (OR = 2.28, p = 0.01, I = 47%). In CT-free studies, HER2-E subtype was associated with pCR in all patients (OR = 5.52, p < 0.001, I = 0%) and in HR + disease (OR = 4.08, p = 0.001, I = 0%). HR-negative status was significantly associated with pCR compared to HR + status in all patients (OR = 2.41, p < 0.001, I = 30%) and within the HER2-E subtype (OR = 1.76, p < 0.001, I = 0%).
CONCLUSIONS
The HER2-E biomarker identifies patients with a higher likelihood of achieving a pCR following neoadjuvant anti-HER2-based therapy beyond HR status and CT use. Future trial designs to escalate or de-escalate systemic therapy in HER2+ disease should consider this genomic biomarker.

Meta-Analysis
OBJECTIVES
To identify clinical factors associated with cancer risk in the idiopathic inflammatory myopathies (IIMs) and to systematically review the existing evidence related to cancer screening.
METHODS
A systematic literature search was carried out on Medline, Embase and Scopus. Cancer risk within the IIM population (i.e. not compared with the general population) was expressed as risk ratios (RR) for binary variables and weighted mean differences (WMD) for continuous variables. Evidence relating to cancer screening practices in the IIMs were synthesized via narrative review.
RESULTS
Sixty-nine studies were included in the meta-analysis. DM subtype (RR 2.21), older age (WMD 11.19), male sex (RR 1.53), dysphagia (RR 2.09), cutaneous ulceration (RR 2.73) and anti-transcriptional intermediary factor-1 gamma positivity (RR 4.66) were identified as being associated with significantly increased risk of cancer. PM (RR 0.49) and clinically amyopathic DM (RR 0.44) subtypes, Raynaud's phenomenon (RR 0.61), interstitial lung disease (RR 0.49), very high serum creatine kinase (WMD -1189.96) or lactate dehydrogenase (WMD -336.52) levels, and anti-Jo1 (RR 0.45) or anti-EJ (RR 0.17) positivity were identified as being associated with significantly reduced risk of cancer. Nine studies relating to IIM-specific cancer screening were included. CT scanning of the thorax, abdomen and pelvis appeared to be effective in identifying underlying asymptomatic cancers.
CONCLUSION
Cancer risk factors should be evaluated in patients with IIM for risk stratification. Screening evidence is limited but CT scanning could be useful. Prospective studies and consensus guidelines are needed to establish cancer screening strategies in IIM patients.

Meta-Analysis Review
BACKGROUND
Targeted therapies directed at specific driver oncogenes have improved outcomes for individuals with advanced non-small cell lung cancer (NSCLC). Approximately 5% of lung adenocarcinomas, the most common histologic subtype of NSCLC, harbour rearrangements in the anaplastic lymphoma kinase (ALK) gene leading to constitutive activity of the ALK kinase. Crizotinib was the first tyrosine kinase inhibitor (TKI) demonstrated to be effective in advanced NSCLC. Next-generation ALK TKIs have since been developed including ceritinib, alectinib, brigatinib, ensartinib, and lorlatinib, and have been compared with crizotinib or chemotherapy in randomised controlled trials (RCTs). These ALK-targeted therapies are currently used in clinical practice and are endorsed in multiple clinical oncology guidelines.
OBJECTIVES
To evaluate the safety and efficacy of ALK inhibitors given as monotherapy to treat advanced ALK-rearranged NSCLC.
SEARCH METHODS
We conducted electronic searches in the Cochrane Lung Cancer Group Specialised Register, Cochrane Central Register of Controlled Trials, MEDLINE, and Embase. We also searched conference proceedings from the American Society for Clinical Oncology (ASCO), European Society of Medical Oncology (ESMO), and International Association for the Study of Lung Cancer (IASLC) World Conference on Lung Cancer, as well as the reference lists of retrieved articles. All searches were conducted from 2007 until 7 January 2021.
SELECTION CRITERIA
We included RCTs comparing ALK inhibitors with cytotoxic chemotherapy or another ALK inhibitor in individuals with incurable locally advanced or metastatic pathologically confirmed ALK-rearranged NSCLC.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed studies for eligibility, extracted study characteristics and outcome data, and assessed risk of bias using the Cochrane risk of bias tool for each included study. We assessed the certainty of evidence using GRADE. Primary outcomes were progression-free survival (PFS) and adverse events (AE); secondary outcomes were overall survival (OS), OS at one year, overall response rate (ORR) by RECIST (Response Evaluation Criteria in Solid Tumours) criteria, and health-related quality of life (HRQoL). We performed a meta-analysis for all outcomes, where appropriate, using the fixed-effect model. We reported hazard ratios (HR) for PFS, OS, and a composite HRQoL of life outcome (time to deterioration), and risk ratios (RR) for AE, ORR, and one-year OS. We presented 95% confidence intervals (95% CIs) and used the I² statistic to investigate heterogeneity. We planned comparisons of 'ALK inhibitor versus chemotherapy' and 'next-generation ALK inhibitor versus crizotinib' with subgroup analysis by type of ALK inhibitor, line of treatment, and baseline central nervous system involvement.
MAIN RESULTS
Eleven studies (2874 participants) met our inclusion criteria: six studies compared an ALK inhibitor (crizotinib, ceritinib, and alectinib) to chemotherapy, and five studies compared a next-generation ALK inhibitor (alectinib, brigatinib, and lorlatinib) to crizotinib. We assessed the evidence for most outcomes as of moderate to high certainty. Most studies were at low risk for selection, attrition, and reporting bias; however, no RCTs were blinded, resulting in a high risk of performance and detection bias for outcomes reliant on subjective measurement. ALK inhibitor versus chemotherapy Treatment with ALK inhibitors resulted in a large increase in PFS compared to chemotherapy (HR 0.45, 95% CI 0.40 to 0.52, 6 RCTs, 1611 participants, high-certainty evidence). This was found regardless of line of treatment. ALK inhibitors may result in no difference in overall AE rate when compared to chemotherapy (RR 1.01, 95% CI 1.00 to 1.03, 5 RCTs, 1404 participants, low-certainty evidence). ALK inhibitors slightly improved OS (HR 0.84, 95% CI 0.72 to 0.97, 6 RCTs, 1611 participants, high-certainty evidence), despite most included studies having a significant number of participants crossing over from chemotherapy to receive an ALK inhibitor after the study period. ALK inhibitors likely increase ORR (RR 2.43, 95% CI 2.16 to 2.75, 6 RCTs, 1611 participants, moderate-certainty evidence) including in measurable baseline brain metastases (RR 4.88, 95% CI 2.18 to 10.95, 3 RCTs, 108 participants) when compared to chemotherapy. ALK inhibitors result in a large increase in the HRQoL measure, time to deterioration (HR 0.52, 95% CI 0.44 to 0.60, 5 RCTs, 1504 participants, high-certainty evidence) when compared to chemotherapy. Next-generation ALK inhibitor versus crizotinib Next-generation ALK inhibitors resulted in a large increase in PFS (HR 0.39, 95% CI 0.33 to 0.46, 5 RCTs, 1263 participants, high-certainty evidence), particularly in participants with baseline brain metastases. Next-generation ALK inhibitors likely result in no difference in overall AE (RR 1.00, 95% CI 0.98 to 1.01, 5 RCTs, 1263 participants, moderate-certainty evidence) when compared to crizotinib. Next-generation ALK inhibitors likely increase OS (HR 0.71, 95% CI 0.56 to 0.90, 5 RCTs, 1263 participants, moderate-certainty evidence) and slightly increase ORR (RR 1.18, 95% CI 1.10 to 1.25, 5 RCTs, 1229 participants, moderate-certainty evidence) including a response in measurable brain metastases (RR 2.45, 95% CI 1.7 to 3.54, 4 RCTs, 138 participants) when compared to crizotinib. Studies comparing ALK inhibitors were conducted exclusively or partly in the first-line setting.
AUTHORS' CONCLUSIONS
Next-generation ALK inhibitors including alectinib, brigatinib, and lorlatinib are the preferred first systemic treatment for individuals with advanced ALK-rearranged NSCLC. Further trials are ongoing including investigation of first-line ensartinib. Next-generation inhibitors have not been compared to each other, and it is unknown which should be used first and what subsequent treatment sequence is optimal.

Review
Compound epidermal growth factor receptor () mutations represent a heterogeneous subgroup of non-small cell lung cancer (NSCLC) patients with uncommon mutations. We conducted a systematic review to investigate the available data on this patients' subgroup. Overall, we found a high heterogeneity in the incidence of compound mutations (4-26% of total mutant cases), which is dependent on the different testing methods adopted and the specific mutations considered. In addition, the relative incidence of distinct compound subclasses identified is reported with extreme variability in different studies. Preclinical and clinical data, excluding exon 20 p.T790M compound mutations, show good responses with EGFR tyrosine kinase inhibitors (TKIs) (combined common mutations: response rate (RR) ≥ 75% with either first- or second-generation TKIs; combined common plus uncommon: RR 40-80% and 100% with first-generation TKIs and afatinib, respectively; combined uncommon: RR 20-70%, ~80% and ~75% with first-generation TKIs, afatinib and osimertinib, respectively). Overall, data are consistent in supporting the use of EGFR TKIs in treating compound mutations, taking into account different sensitivity profile of accompanying mutations for selecting the most adequate EGFR TKI for individual patients.

Receptor-interacting serine/threonine-protein kinase 1 (RIPK1) is a key mediator of cell death and inflammation. The unique hydrophobic pocket in the allosteric regulatory domain of RIPK1 has enabled the development of highly selective small-molecule inhibitors of its kinase activity, which have demonstrated safety in preclinical models and clinical trials. Potential applications of these RIPK1 inhibitors for the treatment of monogenic and polygenic autoimmune, inflammatory, neurodegenerative, ischaemic and acute conditions, such as sepsis, are emerging. This article reviews RIPK1 biology and disease-associated mutations in RIPK1 signalling pathways, highlighting clinical trials of RIPK1 inhibitors and potential strategies to mitigate development challenges.

Meta-Analysis
PURPOSE
To update recommendations of the ASCO systemic therapy for hormone receptor (HR)-positive metastatic breast cancer (MBC) guideline.
METHODS
An Expert Panel conducted a systematic review to identify new, potentially practice-changing data.
RESULTS
Fifty-one articles met eligibility criteria and form the evidentiary basis for the recommendations.
RECOMMENDATIONS
Alpelisib in combination with endocrine therapy (ET) should be offered to postmenopausal patients, and to male patients, with HR-positive, human epidermal growth factor receptor 2 (HER2)-negative, -mutated, ABC, or MBC following prior endocrine therapy with or without a cyclin-dependent kinase (CDK) 4/6 inhibitor. Clinicians should use next-generation sequencing in tumor tissue or cell-free DNA in plasma to detect mutations. If no mutation is found in cell-free DNA, testing in tumor tissue, if available, should be used as this will detect a small number of additional patients with mutations. There are insufficient data at present to recommend routine testing for mutations to guide therapy for HR-positive, HER2-negative MBC. For or mutation carriers with metastatic HER2-negative breast cancer, olaparib or talazoparib should be offered in the 1st-line through 3rd-line setting. A nonsteroidal aromatase inhibitor (AI) and a CDK4/6 inhibitor should be offered to postmenopausal women with treatment-naïve HR-positive MBC. Fulvestrant and a CDK4/6 inhibitor should be offered to patients with progressive disease during treatment with AIs (or who develop a recurrence within 1 year of adjuvant AI therapy) with or without one line of prior chemotherapy for metastatic disease, or as first-line therapy. Treatment should be limited to those without prior exposure to CDK4/6 inhibitors in the metastatic setting.Additional information can be found at www.asco.org/breast-cancer-guidelines.

Review
BACKGROUND
Evaluation of health-related quality of life (HR-QoL) among cancer patients has gained an increasing importance and is now a key determinant of anticancer treatments' value. HR-QoL has been assessed in trials testing cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) in breast cancer (BC), using various questionnaires at different timepoints. HR-QoL reports from BC patients treated with CDK4/6i in the real-world setting are also available.
METHODS
We systematically reviewed the literature, searching for full-length articles, and selected conference abstracts reporting data on HR-QoL in BC patients at any stage and of any molecular subtype treated with abemaciclib, palbociclib or ribociclib.
RESULTS
A total of 533 full-length articles and 143 abstracts were retrieved. After screening for eligibility, 38 records were included (31 clinical trials; 7 real-world reports). Assessment methods were heterogeneous across studies in terms of questionnaires, evaluation timepoints and endpoints. Overall, adding CDK4/6i to endocrine therapy did not worsen patients' HR-QoL, with a positive trend towards pain improvement. Gastrointestinal scores (diarrhea, nausea and appetite loss) statistically favored the control arm among metastatic BC patients receiving abemaciclib, whereas they were superimposable in the early setting. The combination of palbociclib and endocrine therapy showed similar HR-QoL outcomes compared with endocrine therapy alone, but determined better scores compared with chemotherapy. HR-QoL was specifically assessed in premenopausal patients treated with ribociclib, showing similar scores compared with postmenopausal patients.
CONCLUSIONS
Despite methodological heterogeneity does not allow a proper comparison, HR-QoL was generally maintained with CDK4/6i. However, differences between abemaciclib, palbociclib and ribociclib exist and mainly rely on the distinct safety profiles of the compounds. These differences should be acknowledged and taken into account in the clinical practice.
