Background: The multidisciplinary team (MDT) has been carried out in many large hospitals now. However, given the costs of time and money and with little strong evidence of MDT effectiveness being reported, critiques of MDTs persist., Aim: To evaluate the effects of MDTs on patients with synchronous colorectal liver metastases and share our opinion on management of synchronous colorectal liver metastases., Methods: In this study we collected clinical data of patients with synchronous colorectal liver metastases from February 2014 to February 2017 in the Chinese People's Liberation Army General Hospital and subsequently divided them into an MDT+ group and an MDT- group. In total, 93 patients in MDT+ group and 169 patients in MDT- group were included totally., Results: Statistical increases in the rate of chest computed tomography examination ( P = 0.001), abdomen magnetic resonance imaging examination ( P = 0.000), and preoperative image staging ( P = 0.0000) were observed in patients in MDT+ group. Additionally, the proportion of patients receiving chemotherapy ( P = 0.019) and curative resection ( P = 0.042) was also higher in MDT+ group. Multivariable analysis showed that the population of patients assessed by MDT meetings had higher 1-year [hazard ratio (HR) = 0.608, 95% confidence interval (CI): 0.398-0.931, P = 0.022] and 5-year (HR = 0.694, 95%CI: 0.515-0.937, P = 0.017) overall survival., Conclusion: These results proved that MDT management did bring patients with synchronous colorectal liver metastases more opportunities for comprehensive examination and treatment, resulting in better outcomes., Competing Interests: Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article., (©The Author(s) 2023.

To study the diagnostic value of video EEG (V-EEG) and imaging examination for children with secondary epilepsy. A total of 168 children with epilepsy, who were treated in First Hospital of Qinhuangdao from March 2014 to April 2017, were selected in this study. V-EGG and magnetic resonance imaging (MRI) diagnosis were performed in all children respectively, and the diagnostic value of the two methods was compared. Among the 168 patients, abnormal EEG signals were detected in 154 patients (120 patients had epileptiform discharges), V-EEG showed that the distribution of epileptiform discharges in the left and right leads were significantly higher than that in bilateral leads, and the differences were significant (P<0.05). MRI test showed that 140 patients had intracranial structural lesions or abnormal development, and 28 patients were not found abnormal. Among the 168 cases, 72 cases were pure partial type, the highest proportion was 42.86%; Among the main causes, the type of intracranial infection was mainly systemic, accounting for 11.31%. The type of cerebral infarction was mainly partial type, accounting for 8.33%. The main types of intracranial softening lesions were complex part, accounting for 6.55%. The type of intracranial tumor was mainly partial type, accounting for 6.55%. The location ofMRI was mainly unilateral, in which the left side was 38.10%and the right side was 29.76%. V-EEG monitoring showed abnormal discharge was found in 154 cases, accounting for 91.67%, of which intracranial infection and cerebral infarction, as well as intracranial tumors and intracranial softening of the positive detection rate were the highest, respectively 24.40%, 13.10%, 11.90% and 10.71%. The sensitivity and specificity ofV-EEGdiagnosis were significantly higher than those ofMRI (P<0.05). V-EEG is more valuable than MRI in the diagnosis of secondary epilepsy. It can provide more accurate diagnostic data and is worthy of promotion and application in the clinical diagnosis and treatment. [ABSTRACT FROM AUTHOR]

Objective To evaluate the clinical application of 15-channel phased-array head coil and 6-channel dS Flex M surface coil in MRI imaging of temporomandibular joint. Methods Totally 50 patients were randomly equally assigned into two groups, of whom, one group used a 15-channel phase-array head coil for MRI scanning, and the other applied a6- channel dS Flex M surface coil. The same regions of interest were set up to measure and analyze the signal to noise ratio (SNR) and contrast to noise ratio (CNR) of each region respectively. SPSS 19.0 software was used for quantitative analysis. Results The head coil had the SNR and the CNR higher than those of the surface coil. The head coil and Flex surface coil had the imaging diagnosis rates being 95.83% and 91.67% respectively, and there was no significant difference between them (P> 0.05). Conclusion Both phase-array head coil and dS Flex M surface coil can be used for temporomandibular joint MRI imaging, and it's suggested that conventional imaging be executed with dS Flex M surface coil and functional imaging be implemented with head coil.

Mixed-type liver cancer is a rare kind of primary malignant liver tumor with risk factors similar to those of hepatocellular carcinoma and intrahepatic cholangiocarcinoma, although treatment methods and prognosis differ. An early imaging diagnosis is helpful in adopting appropriate treatment strategies for mixed-type liver cancer. Since mixed-type liver cancer contains different proportions of hepatocellular carcinoma and cholangiocarcinoma in the same lesion, imaging manifestations may vary. This paper reviews the recent literature reports, imaging characteristics, and the latest imaging diagnostic techniques in relation to the imaging diagnosis of mixed-type liver cancer.

Pulmonary large cell neuroendocrine carcinoma (LCNEC) is a rare subtype of malignant pulmonary tumor. The incidence rate of LCNEC was reported to be 0.3%-3% in lung cancers. Although LCNEC is classified as non-small cell lung cancer (NSCLC), it is more aggressive and malignant than other NSCLC, and its biological behavior is similar to that of small cell lung cancer (SCLC). Most of the LCNEC patients are elderly smoking male and the clinical manifestations are not specific. The imaging manifestations of the tumors are often located in the periphery and the upper lobes, and the enlargement of mediastinal or hilar lymph nodes is common. The diagnosis is mainly based on pathology by the histological features and immunohistochemistry (IHC). Specific neuroendocrine markers such as chromogranin A (CgA), synaptophysin (Syn) and CD56 are usually diffusely positive in LCNEC, and found that insulinoma-associated protein (INSM1) and high rate of Ki-67 are helpful for diagnosis. More differential diagnoses also increase the difficulty of correctly diagnosing LCNEC. The rise of LCNEC molecular typing in recent years may be helpful for diagnosis and subsequent treatment. This review focuses on the epidemiological features, imaging studies, pathology, diagnosis, treatment, and prognosis of LCNEC., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Yang, Fan and Lu.)

Objective: To summarize the evaluation methods of postoperative healing of supraspinatus tendon tear in recent years, in order to provide reference for clinic., Methods: CNKI, Wanfang, PubMed, and Foreign Medical Literature Retrieval Service (FMRS) databases were used to search the literatures between 2005 and 2022. The literature related to the diagnosis and postoperative healing of supraspinatus tendon tear was included. Finally, 50 articles were reviewed., Results: Supraspinatus tendon tear is a common shoulder disease. Physical examination, clinical score, and imaging examination are used to predict and evaluate the postoperative healing. Among them, physical examination and clinical score are non-invasive and the most economical methods, but their accuracy and sensitivity are lower than imaging examination, so they can only be used as auxiliary methods. The acromio-humeral distance (AHD) and upward migration index (UMI) measured by X-ray films can directly reflect the change of supraspinatus tendon thickness, but they are impossible to distinguish whether there is tear or not. Ultrasound and MRI are the main methods for the clinical diagnosis of supraspinatus tendon tear, but the commonly used MRI sequence can not accurately judge the internal healing of the tendon. Shear wave elastrography (SWE) and ultrashort-echo-time (UTE) techniques are the latest research directions in recent years, but different studies have shown opposite conclusions on the application of SWE technique. This conclusion shows that the principle of SWE technique and its relationship with tendons need to be further studied. UTE technique has good clinical effect, and the T2* value obtained by UTE technique is more accurate than that of traditional Sugaya typing, but there are still few research samples., Conclusion: AHD and UMI measured by X-ray film and T2* value measured by UTE technique can be used as effective methods for evaluating the healing of supraspinatus tendon tear after repairing, and can be used as a follow-up evaluation method combined with physical examination and clinical score for patients with supraspinatus tendon tear.

Abstract: Radiation-induced optic neuropathy (RION) is a rare but devastating late complication of radiotherapy, usually manifesting months to years after cancer treatment of the head and neck, resulting in rapidly progressive blindness in one or both eyes. The incidence of radiation-induced complications following radiotherapy, especially RION, is correlated with survival time of patients. Nasopharyngeal carcinoma (NPC), the most common type of cancer in southern China, has been primarily treated with radiotherapy, with associated neural injuries. To our knowledge, there are few reports of RION among patients with NPC who have undergone radiotherapy. To study this further, we reviewed nine patients with NPC and RION after radiotherapy and examined the clinical manifestations of RION, characteristics of the ophthalmologic examination, MRI results and the treatments used. Of the nine patients with RION, the most frequent clinical presentation was a decline of vision with visual field defects in one or both eyes. Ophthalmologic examinations showed flame hemorrhages in the retina, optic nerve atrophy and cotton wool spots. T1-weighted enhanced MRI showed enhancement of the optic nerve and optic chiasm in six patients. Treatment with corticosteroids, anticoagulation and hyperbaric oxygen (HBO) treatment did not reduce visual loss or blindness in patients. [Copyright &y& Elsevier]

Objective: Axillary lymph node management is an important part of breast cancer surgery and the accuracy of preoperative imaging evaluation can provide adequate information to guide operation. Different molecular subtypes of breast cancer have distinct imaging characteristics. This article was aimed to evaluate the predictive ability of imaging methods in accessing the status of axillary lymph node in different molecular subtypes., Methods: A total of 2,340 patients diagnosed with primary invasive breast cancer after breast surgery from 2013 to 2018 in Jiangsu Breast Disease Center, the First Affiliated Hospital with Nanjing Medical University were included in the study. We collected lymph node assessment results from mammography, ultrasounds, and MRIs, performed receiver operating characteristic (ROC) analysis, and calculated the sensitivity and specificity of each test. The C-statistic among different imaging models were compared in different molecular subtypes to access the predictive abilities of these imaging models in evaluating the lymph node metastasis., Results: In Her-2 + patients, the C-statistic of ultrasound was better than that of MRI (0.6883 vs. 0.5935, p=0.0003). The combination of ultrasound and MRI did not raise the predictability compared to ultrasound alone (p=0.492). In ER/PR+HER2- patients, the C-statistic of ultrasound was similar with that of MRI (0.7489 vs. 0.7650, p=0.5619). Ultrasound+MRI raised the prediction accuracy compared to ultrasound alone (p=0.0001). In ER/PR-HER2- patients, the C-statistics of ultrasound was similar with MRI (0.7432 vs. 0.7194, p=0.5579). Combining ultrasound and MRI showed no improvement in the prediction accuracy compared to ultrasound alone (p=0.0532)., Conclusion: From a clinical perspective, for Her-2+ patients, ultrasound was the most recommended examination to assess the status of axillary lymph node metastasis. For ER/PR+HER2- patients, we suggested that the lymph node should be evaluated by ultrasound plus MRI. For ER/PR-Her2- patients, ultrasound or MRI were both optional examinations in lymph node assessment. Furthermore, more new technologies should be explored, especially for Her2+ patients, to further raise the prediction accuracy of lymph node assessment., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Zheng, Huang, Peng, Xia, Cui, Han, Wang and Xie.)

PURPOSE: To investigate the diagnosis and therapeutic approaches of carotid body tumor (CBT). METHODS: In this study, the medical records of 19 patients with carotid body tumor were reviewed retrospectively. These patients had been referred to the Department of Oral and Maxillofacial Surgery in Shandong Provincial Hospital from 1999 to 2004. RESULTS: B ultrasound, DSA, MRI, CTA were used as the modalities of diagnosis for 19 CBT cases. All patients were submitted to surgical resection of the tumor. Among them, preoperative Matas test was carried out in 7 patients. Monitoring retrograde stump pressure of internal carotid artery was performed in all the cases during the operations. 11 patients underwent TCD examination before and during operation. Internal shunt was applied in 5 cases. Postoperatively, paralysis of hypoglossal never occurred in 4 patients, paralysis of pneumogastric never occurred in one patient, no hemiplegia and death occurred. CONCLUSIONS: DSA CTA, MRI are more effective modalities to diagnose CBT. The way of choosing local anaesthesia firstly and then general anaesthesia is preferable. Monitoring of TCD, retrograde stump pressure of internal carotid artery and internal shunt application are the keys for successful Surgery. [ABSTRACT FROM AUTHOR]

Introduction: To investigate the effectiveness of the case management mode on the application of smear-positive pulmonary tuberculosis patients., Methodology: This was a randomized control trial. A total of 70 newly diagnosed smear-positive pulmonary tuberculosis patients were recruited and been randomly divided into experimental group and control group, with 35 participants in each group. In the experimental group, patients received the tuberculosis case management mode based on the conventional management mode. In the control group, patients received the routine management mode. We compared the knowledge, attitude, and practice score; sputum-negative conversion rate, effective imaging rate of the two groups at the time of initial admission, discharge, and one month after discharge., Results: The results showed that there was no significant difference in baseline data between the two groups (p > 0.05); at the time of discharge and one month after discharge, the knowledge, belief, behavior, sputum-negative conversion rate, and imaging examination effective rate of the experimental group were higher than those of the control group (p < 0.05)., Conclusions: The case management mode can improve the knowledge, attitude, and practice level; sputum-negative conversion rate; and imaging efficiency of newly treated smear-positive pulmonary tuberculosis patients., Competing Interests: No Conflict of Interest is declared, (Copyright (c) 2021 YanLing Li, Ying Wang, GaiJing Wang, YiLin Wang, YanQing Tian, SiWei Zhu, Jiao Chen, LiLi Diao.)

Background: Desmoid fibroma is a rare soft tissue tumor originating from the aponeurosis, fascia, and muscle, and it is also known as aponeurotic fibroma, invasive fibroma, or ligamentous fibroma., Aim: To investigate the clinical and imaging features of desmoid tumors of the extremities., Methods: Thirteen patients with desmoid fibroma of the extremities admitted to our hospital from October 2016 to March 2021 were included. All patients underwent computed tomography (CT), magnetic resonance imaging (MRI), and pathological examination of the lesion. Data on the diameter and distribution of the lesion, the relationship between the lesion morphology and surrounding structures, MRI and CT findings, and pathological features were statistically analyzed., Results: The lesion diameter ranged from 1.7 to 8.9 cm, with an average of 5.35 ± 2.39 cm. All lesions were located in the deep muscular space, with the left and right forearm each accounting for 23.08% of cases. Among the 13 patients with desmoid fibroma of the extremities, the lesions were "patchy" in 1 case, irregular in 10, and quasi-round in 2. The boundary between the lesion and surrounding soft tissue was blurred in 10 cases, and the focus infiltrated along the tissue space and invaded the adjacent structures. Furthermore, the edge of the lesion showed "beard-like" infiltration in 2 cases; bone resorption and damage were found in 8, and bending of the bone was present in 2; the boundary of the focus was clear in 1. According to the MRI examination, the lesions were larger than 5 cm (61.54%), round or fusiform in shape (84.62%), had an unclear boundary (76.92%), showed uniform signal (69.23%), inhomogeneous enhancement (84.62%), and "root" or "claw" infiltration (69.23%). Neurovascular tract invasion was present in 30.77% of cases. CT examination showed that the desmoid tumors had slightly a lower density (69.23%), higher enhancement (61.54%), and unclear boundary (84.62%); a CT value < 50 Hu was present in 53.85% of lesions, and the enhancement was uneven in 53.85% of cases. Microscopically, fibroblasts and myofibroblasts were arranged in strands and bundles, without obvious atypia but with occasional karyotyping; cells were surrounded by collagen tissue. There were disparities in the proportion of collagen tissue in different regions, with abundant collagen tissue and few tumor cells in some areas, similar to the structure of aponeuroses or ligaments, and tumor cells invading the surrounding tissues., Conclusion: Desmoid tumors of the extremities have certain imaging features on CT and MRI. The two imaging techniques can be combined to improve the diagnostic accuracy, achieve a comprehensive diagnosis of the disease in the clinical practice, and reduce the risk of missed diagnosis or misdiagnosis. In addition, their use can ensure timely diagnosis and treatment., Competing Interests: Conflict-of-interest statement: None., (©The Author(s) 2021. Published by Baishideng Publishing Group Inc.

Purpose: This article reviews the pathological mechanisms and progress of imaging of severe frostbite to assist in the search for targets for clinical diagnosis and treatment of severe frostbite. This review also aims to provide strong evidence for clinical diagnosis and treatment of deep frostbite.Methods: The review was based on the summary and analysis of the existing literature, and explored the pathological mechanism of deep frostbite and the advantages and disadvantages of imaging diagnostic methods.Results: According to the depth of tissue involvement, frostbite is divided into 4 levels. Severe frostbite includes Grade 3 and Grade 4 frostbite. Clinical performance evaluation and imaging diagnostic research have always been the mainstream of severe frostbite diagnosis. Imaging methods focus on vascular patency and tissue vitality. This article introduces angiography, SETCT/CT and MRA, and we summarize the advantages and disadvantages of these imaging methods. We recommend corresponding imaging modalities according to the state of frostbite patients.Conclusions: Imaging examination, especially angiography and bone scans, provide useful information for determining the diagnosis and prognosis of severe frostbite. In order to obtain a good clinical prognosis, clinicians should first perform SPECT/CT. MRA does not burden the patient's body, but the balance between cost and benefit must be considered. Angiography provides a good feedback on the changes in blood vessel status before and after treatment, which is helpful for discovering the response of limbs to treatment. [ABSTRACT FROM AUTHOR]

Ectopic spleen is a rare clinical malformation in which the spleen is relocated from its normal anatomical position to other parts of the abdomen. We report a rare case of abdominopelvic ectopic spleen caused by splenic ligament deficiency. A patient experienced intermittent pain in the left upper abdomen that was progressively aggravated. This was confirmed by comprehensive imaging examinations and postoperative pathology. We also performed a review of the literature on the current state of the field. Our data may help to improve the diagnosis and treatment of ectopic spleen.

The outbreak of coronavirus disease 2019 (COVID-19) is a huge threat to global public health because it develops rapidly. There is no specific treatment so far. Chest imaging examination is an important auxiliary examination method in diagnosis of COVID-19. To further standardize the imaging examination and diagnosis of COVID-19, Hunan Society of Radiology together with Imaging Technology Professional Committee of Hunan Medical Association reach an expert consensus document on imaging examination, diagnosis, and control and prevention of nosocomial infection for COVID-19. This document summarizes the epidemiological characteristics, clinical features, imaging examination procedure, imaging findings, CT staging, the value of imaging examination, and the methods for control and prevention of nosocomial infection for COVID-19 during imaging examination. Furthermore, it extends the clinical characteristics and imaging manifestations of COVID-19 in children.

A transorbital penetrating injury by a foreign body is an extremely rare type of injury, and its severity is often difficult to estimate by examination of the superficial wound alone. Thus, such injuries are challenging for neurosurgeons to investigate and manage. We herein present a peculiar case involving a 3-year-old girl with a penetrating transorbital skull-base injury caused by a coloring pencil and discuss the anatomical location of the foreign body, radiological examination findings, diagnosis, and treatment strategy. The pencil was completely removed by manual extraction. Follow-up investigations confirmed a good outcome. Multidisciplinary cooperation, radiological examination, correct diagnosis, timely treatment, and detailed follow-up studies are necessary to manage penetrating transorbital skull-base injuries caused by foreign bodies. The orbital walls are very thin in children, and the orbital roof and superior orbital fissure are often penetrated by foreign bodies in cases such as that described herein. The anatomical location of the foreign body influences the clinical management strategy.

Spinal tuberculosis is a common manifestation of extrapulmonary tuberculosis and osteoarticular tuberculosis. Common clinical manifestations include constitutional symptoms, back pain, spinal tenderness, paraplegia, and spinal deformities. They are the common causes of paralysis and could increase the mortality in patients. Most cases of spinal tuberculosis remaining undiagnosed, and early clinical symptoms and imaging manifestations lack specificity, which explained the reason why it is difficult to identify from atypical spinal metastases, brucellosis and other diseases. The rate of missed diagnosis and misdiagnosis for spinal tuberculosis is high. If spinal tuberculosis diagnostic targets could be early detected, the therapeutic targets can be effectively treated, which can not only control the progress of the disease and shorten the course of treatment, but also reduce the economic pressure and avoid spinal deformity. Therefore, early diagnosis should be our focus. Comprehensive use of a variety of diagnostic targets can improve the early diagnosis rate of spinal tuberculosis. Here, we review the progress of laboratory, imaging and gene detection in the diagnosis of spinal tuberculosis in recent years., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Objective: To compare the diagnostic value of the 2015 American Thyroid Association(ATA) guidelines and the American College of Radiology Thyroid Imaging Reporting and Data System(ACR TI-RADS) classification for thyroid nodules. Method: Retrospective analysis of 340 cases of 386 thyroid nodules confirmed by surgery or pathology from November 2016 to November 2018 in Yan' an University Hospital was conducted, using 2015 ATA, ACR TI-RADS for classification. Histopathology or cytology was the gold standard, The receiver operating characteristic(ROC) curve was plotted, using χ test to compare the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of the two methods. Result: Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of ACR TI-RADS were 961%, 741%, 645%, 974%, 813%, respectively, and the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of the 2015 ATA guidelines was 937%, 733%, 632%, 960%, 801%,respectively. There was no statistically significant difference between the two groups. The area under ACR TI-RADS and 2015 ATA guide curve is 0851 and 0839, respectively. Conclusion: Both ACR TI-RADS and 2015 ATA guidelines have high diagnostic value. The two classification methods are equally effective in assessing the benign and malignant thyroid nodules., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Editorial Department of Journal of Clinical Otorhinolaryngology Head and Neck Surgery.)

Background: Internal carotid artery (ICA) pseudoaneurysms are associated with high mortality if lack of proper management. Patients with ICA pseudoaneurysms in the sphenoid sinus often visit a hospital's ear, nose and throat (ENT) department due to nasal bleeding. In such cases, simple examination and therapy will lead to misdiagnosis., Objective: This study sought to investigate the clinical characteristics, diagnostic methods and treatment of ICA pseudoaneurysms in the sphenoid sinus., Methods: Various data, including clinical features, imaging examination results, and treatment and prognosis information, were collected and analyzed for 8 patients who visited the Department of Otolaryngology, Head & Neck Surgery of West China Hospital from March 2008 to January 2017., Results: The patients included 6 males and 2 females (ages 16 to 56 years). Repeated epistaxis was a common symptom in six of the eight patients (6/8), whereas monocular blindness and binocular blindness were observed in the other two patients. Head trauma was found to play a role in the induction of ICA pseudoaneurysms, given that five patients (5/8) exhibited a specific history of head injury. CT examination tended to result in misdiagnosis, whereas MRI and digital subtraction angiography (DSA) were helpful for obtaining a definite diagnosis with all diagnoses were confirmed via DSA. Coated stent intervention was performed in five patients, while carotid artery ligation was performed in two patients in emergency situations: one of whom exhibited paraplegia, but recovery was ultimately observed after rehabilitation. Moreover, failure of coated stent intervention in one patient was resolved via additional unilateral common carotid artery ligation. Furthermore, one patient with vision loss experienced vision restoration. One patient discontinued treatment for personal reasons and was lost to follow-up. No recurrence was observed in the other 7 patients., Conclusion: ICA pseudoaneurysms in the sphenoid sinus are uncommon. To accurately identify ICA pseudoaneurysms, collaboration between otolaryngologists and imaging specialists is essential. On the other hand, both surgical and interventional treatments can achieve good results; therefore, otolaryngologists should enhance their cooperation with neurosurgery and intervention departments. Accurate diagnosis and rapid treatment are keys to managing ICA pseudoaneurysms., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Ductal carcinoma in situ (DCIS) of the breast has no potential to metastasize, but over 20% of cases preoperatively diagnosed as DCIS are upstaged on final pathology. The rates of upstaging and the predictors for invasion on final pathology were evaluated. For 240 primary breast cancers, radiological findings on mammography, ultrasonography, and magnetic resonance imaging were investigated along with pathological and clinical information. Univariate and multivariate analyses were performed to identify predictors of potential invasion. Of the 240 breast cancers, 68 (28.3%) showed invasion on final pathology, and 5 (2.5%) had sentinel node metastasis. The multivariate analysis identified five independent predictors: non-mass lesions >2.4 cm on ultrasonography (odds ratio [OR] 2.84, 95% confidence interval [CI] 1.02-7.95, p=0.047), comedo-type histology (OR 6.89, 95% CI 1.89-25.08, p<0.01), solid-type histology (OR 7.97, 95% CI 2.08-30.49, p<0.01), palpable mass (OR 2.63, 95% CI 1.05-6.64, p=0.04), and bloody nipple discharge (OR 4.61, 95% CI 1.20-17.66, p=0.02). These five predictors were associated with invasion on final pathology and may help select candidates for sentinel node biopsy., Competing Interests: No potential conflict of interest relevant to this article was reported.

Laryngeal carcinoma is a common malignant tumor in the head and neck, and the squamous cell carcinoma of the larynx is the most prevelance. In view of the importance of laryngeal function and its survival, the choice of the best therapeutic regimen of laryngeal carcinoma must consider the potential survival rate and the change of postoperative function. The margin of laryngeal carcinoma is an important index of preoperative imaging evaluation of laryngeal carcinoma. The accurate determination of the cutting edge determines the operation mode, the success rate, the survival rate and prognosis of the patients with laryngeal carcinoma.In recent years, the method of preoperative evaluation of laryngeal tumors is diverse, including molecular, imaging and endoscopy, among which preoperative imaging is the most common method. The purpose of this study was to summarize the evaluation of different imaging techniques in the assessment of local invasion and recurrence of submucosal tumors in laryngeal carcinoma., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Editorial Department of Journal of Clinical Otorhinolaryngology Head and Neck Surgery.)
