Nomograms Predict Survival in Patients with Anaplastic Thyroid Carcinoma.

Nomograms Predict Survival in Patients with Anaplastic Thyroid Carcinoma. Med Sci Monit. 2019 Nov 09;25:8447-8456 Authors: Qiu B, Li HQ, Chang QG, Yin DT Abstract BACKGROUND Anaplastic thyroid carcinoma (ATC) is a very rare, highly lethal malignant cancer. Our aim in this study was to develop nomograms that predict survival in ATC patients. MATERIAL AND METHODS ATC incidence and mortality were assessed via joinpoint regression analysis of 567 ATC patients selected from the Surveillance, Epidemiology, and End Results 18 Registries Research database. Predictive models were established via univariate and multivariate Cox regression analysis of potential risk factors and used to produce nomograms. Performance of the nomograms in terms of discrimination ability and calibration was evaluated by determining the concordance index (C-index) and by generating calibration plots, respectively. RESULTS The incidence and mortality rates for ATC increased from 2000 to 2015 according to the collected data (p

Nature Reviews Endocrinology, Published online: 09 December 2019; doi:10.1038/s41574-019-0307-2Multikinase inhibitors are effective treatments for thyroid cancers, acting primarily as antiangiogenic agents. This year, advances have been made in selective targeting of RET and BRAF in patients with medullary and anaplastic thyroid cancers, respectively. However, Hürthle cell carcinomas have a unique genomic landscape with no dominant truncal drivers, precluding simplistic approaches to therapeutic targeting.

We report FDG PET/CT images of a 63-year-old woman referred for characterization of osteolytic lesions of the cervical spine. This patient with chronic renal failure had a history of follicular thyroid carcinoma with undifferentiated cells, treated by a total thyroidectomy, completed by radioactive iodine in 2017. Because of cancer history, a FDG PET/CT was performed and showed multiple moderately hypermetabolic osteolytic lesions of the spine from C3 to T1, with joint erosion on CT. A laminectomy was performed for cervical spinal cord decompression and revealed a gouty tophus.

CONCLUSIONS: DNA methylation levels of three markers can be useful for differentiating differentiated thyroid cancer from non-malignant follicular thyroid lesions, and may serve as prognostic biomarkers for predicting recurrent or persistent disease following surgery for differentiated thyroid cancer.

A 75-year-old lady with previously diagnosed moderate mixed aortic valve disease underwent surveillance transthoracic echocardiography (TTE). This showed raised trans-aortic gradients in the presence of normal aortic valve leaflet motion and turbulent colour flow across a calcified left ventricular outflow tract (LVOT). Therefore, in view of possible subaortic stenosis, she was referred for cardiac computed tomography for further characterisation. Past medical history included total thyroidectomy and 2 rounds of radioiodine ablation for follicular thyroid carcinoma 12 months prior.

Multiple fluorescence spectroscopy including SSF, SF, 3DF, UV, FTIR, and molecular modeling were utilized for better understanding the binding interaction between lenvatinib and bovine serum albumin (BSA). SSF spectroscopy results showed lenvatinib quenched the intrinsic fluorescence of BSA in the form of the mixed mechanism. The bin...

We examined the utility of microfluidic digital PCR (dPCR) for detection of BRAF and TERT mutations in thyroid tumors. DNA extracted from 100 thyroid tumors (10 follicular adenomas, 10 follicular cancers, 5 medullary cancers, and 75 papillary thyroid cancer (PTC) were used for detection of BRAF and TERT mutations. Digital PCRs were performed using rare mutation SNP genotyping assays on QuantStudio 3D platform. In PTCs, BRAFV600E was detected by dPCR and Sanger sequencing in 42/75 (56%) and in 37/75 (49%), respectively. BRAFV600E was not detected in other tumors. The ratio of mutant/total BRAF alleles varied from 4.7% to 47...

AbstractThe papillary thyroid carcinoma (PTC) usually shows an excellent prognosis. But some patients suffer recurrence after treatment. Recent progress in RNA sequencing (RNA-Seq) allows us to explore whole-transcriptomic gene expression profiles to develop RNA-seq based predictive model for stratifying the risk of recurrence of PTC. RNA-seq and clinical data from The Cancer Genome Atlas thyroid carcinoma cohort were divided chronologically into a training cohort (before 2011, n  = 240) and a validation cohort (after 2011, n = 239). A risk score model was developed in training cohort using univ...

We describe a rare case of metastatic papillary thyroid carcinoma resulting in endobronchial involvement diagnosed by bronchoscopic biopsy, and successfully managed with argon plasma coagulation ablation. Metastatic involvement of lung by thyroid cancer is common, although presentation with endobronchial disease is rarely encountered. When it occurs, threats to airway patency by luminal obstruction and haemoptysis may occur, requiring prompt recognition and intervention to avoid hypoxia and asphyxiation. Bronchoscopic evaluation is essential for both diagnosis and intervention. To our knowledge, we describe the first case ...

Cervical lymph node resection is the treatment of choice, but ethanol ablation offers a therapeutic option for patients with few nodes unresponsive to radioiodine therapy and who are poor surgical candidates. The ethanol ablation procedure is minimally invasive, guided sonographically, easily and safely repeated, and easily implemented with minimal technology and cost. Transient nerve injury is infrequent and virt...

Authors: Kifle E, Hussein M, Alemu J, Tigeneh W Abstract Background: Anemia is a common finding in cancer, which is caused by many factors. It is a major cause of morbidity in cancer patients, worsens disease status and impairs treatment outcome; however, little is known about the prevalence of anemia and associated factors among cancer patients during diagnosis in developing countries like Ethiopia. In response to this, we have conducted research with the aim of assessing the prevalence of anemia and associated factors among newly diagnosed patients with solid malignancy at Tikur Anbessa Specialized Hospital (TASH...
