Abstract
Background: Brain metastases (BM) are the most common intracranial neoplasms in adults and are a significant cause of morbidity and mortality. The brain is an unusual site for distant metastases of thyroid cancer; indeed, the most common sites are lungs and bones. In this narrative review, we discuss about the clinical characteristics, diagnosis, and treatment options for patients with BM from differentiated thyroid cancer (DTC). Summary: BM can be discovered before initial therapy due to symptoms, but in most patients, BM is diagnosed during follow-up because of imaging performed before starting tyrosine kinase inhibitors (TKI) or due to the onset of neurological symptoms. Older male patients with follicular thyroid cancer (FTC), poorly differentiated thyroid cancer (PDTC), and distant metastases may have an increased risk of developing BM. The gold standard for detection of BM is magnetic resonance imaging with contrast agent administration, which is superior to contrast-enhanced computed tomography. The treatment strategies for patients with BM from DTC remain controversial. Patients with poor performance status are candidates for palliative and supportive care. Neurosurgery is usually reserved for cases where symptoms persist despite medical treatment, especially in patients with favorable prognostic factors and larger lesions. It should also be considered for patients with a single BM in a surgically accessible location, particularly if the primary disease is controlled without other systemic metastases. Additionally, stereotactic radiosurgery (SRS) may be the preferred option for treating small lesions, especially those in inaccessible areas of the brain or when surgery is not advisable. Whole brain radiotherapy is less frequently used in treating these patients due to its potential side effects and the debated effectiveness. Therefore, it is typically reserved for cases involving multiple BM that are too large for SRS. TKIs are effective in patients with progressive radioiodine-refractory thyroid cancer and multiple metastases. Conclusions: Although routine screening for BM is not recommended, older male patients with FTC or PDTC and distant metastases may be at higher risk and should be carefully evaluated for BM. According to current data, patients who are suitable for neurosurgery seem to have the highest survival benefit, while SRS may be appropriate for selected patient.

Abstract
Introduction Brain metastasis in differentiated thyroid cancer (DTC) is rare (frequency < 1%) and has a poor prognosis. Treatment strategies for brain metastasis are not well established. Objectives We conducted a retrospective analysis to identify predictive factors for patient outcomes and verify surgical indications for patients with brain metastasis and DTC. Methods The study included 34 patients with pathologically confirmed DTC with brain metastasis from March 2008 to November 2020. The associations between overall survival (OS) and clinical factors were evaluated. Cox regression analysis was used to determine the relationship between clinical factors and OS. To assess the survival benefit of craniotomy, Kaplan-Meier survival analysis was performed for each variable whose statistical significance was determined by Cox regression analysis. Results The median OS of the entire patient sample was 11.4 months. Survival was affected by the presence of lung metastasis (P = 0.033) and the number of brain metastases (n > 3) (P = 0.039). Only the subgroup with the number of brain metastases ≤3 showed statistical significance in the subgroup analysis of survival benefit following craniotomy (P = 0.048). Conclusions The number of brain metastases and the existence of lung metastasis were regarded more essential than other clinical factors in patients with DTC in this study. Furthermore, craniotomies indicated a survival benefit only when the number of brain metastases was ≤3. This finding could be beneficial in determining surgical indications in thyroid cancer with brain metastasis.

Abstract
BACKGROUND Extrahepatic metastasis (EHM) from hepatocellular carcinoma (HCC) occurs in 10%–15% of cases following initial treatment. The most frequent sites of EHM are the lung, lymph nodes, and bone. Gastrointestinal or brain metastasis from HCC is rarely reported. Here, we report a rare case of concurrent HCC metastases to the stomach, colon, and brain.
CASE SUMMARY A 72-year-old male with a history of alcohol induced HCC presented with multiple intrahepatic recurrences and tumorous lesions in the stomach and ascending colon. Three years earlier, he underwent right hemihepatectomy, and 1 year ago, he had a video-assisted thoracoscopic wedge resection for pulmonary metastasis of HCC. We decided on surgical resection of the new metastases because of massive gastric bleeding and concern for possible colonic obstruction. The patient underwent gastric wedge resection and right hemicolectomy. Two weeks later, the patient developed dysarthria and mild cognitive disorder. Magnetic resonance imaging of the brain revealed a left frontal lobe lesion, and he underwent resection of a metastatic brain tumor. Unfortunately, he died 6 weeks after the last surgery due to hepatorenal syndrome.
CONCLUSION Decision of surgery was carefully recommended in this case and may extend survival in other metastatic HCC patients with well-preserved hepatic function.

[PMID: 31957916 DOI: 10.1634/theoncologist.2019-0633] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2019] [Accepted: 12/12/2019] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Because beneficial response and progression-free survival (PFS) were achieved by well-designed clinical trials with tyrosine kinase inhibitors (TKIs) in patients with progressive radioiodine-refractory differentiated thyroid cancer (RR-DTC), the overall survival (OS) and improvement of therapeutic outcomes in the real world have been anticipated. SUBJECTS, MATERIALS, AND METHODS This prospective, single-center, real-world study assessed the predictive significance of clinicopathological features on disease control rate (DCR), objective response rate (ORR), PFS, and OS in a cohort of 72 patients with progressive RR-DTC treated with sorafenib at an initial dose of 200 mg twice daily. RESULTS Disease control, objective response, and biochemical effectiveness were achieved in 73.3%, 21.7%, and 77.9% of patients, respectively. The median PFS and OS were 17.6 and 28.9 months, respectively. Multivariate analyses showed that hand-foot syndrome (HFS) was an independent predictor for better DCR and ORR, and 131 I-avidity for higher ORR. In univariate analyses, longer PFS and OS were observed in patients with Eastern Cooperative Oncology Group performance status (ECOG PS) ≤2, pathologically well DTC, lung-only metastasis, absence of bone metastasis, biochemically nonineffective response, HFS, or radiological disease control. In multivariate analyses, only well DTC and ECOG PS ≤2 remained as independent prognostic factors for more favorable PFS and OS, respectively, whereas the absence of bone metastasis and biochemically nonineffective response independently predicted superior PFS and OS. CONCLUSION This study demonstrated that clinicopathological features might play a vital role in predicting therapeutic outcomes in patients with progressive RR-DTC treated with sorafenib, warranting further optimization of candidates for TKIs. IMPLICATIONS FOR PRACTICE This prospective, single-center, real-world study was designed to investigate the significance of clinicopathological features in predicting response, progression-free survival, and overall survival in patients with progressive radioiodine-refractory differentiated thyroid cancer (DTC) treated with sorafenib. Multivariate analyses showed that hand-foot syndrome was an independent predictor for better response. Meanwhile, well DTC, Eastern Cooperative Oncology Group performance status ≤2, biochemically nonineffective response, and the absence of bone metastasis were independent prognostic factors for more favorable survival. This study demonstrated that clinicopathological features might play a vital role in predicting outcomes in sorafenib-treated patients with radioiodine-refractory DTC, warranting optimization of indications.

Abstract
Apatinib, an oral small molecular receptor tyrosine kinase inhibitor (TKI) developed first in China, exerts antiangiogenic and antineoplastic function through selectively binding and inhibiting vascular endothelial growth factor receptor 2 (VEGFR-2). In this study, we aimed to explore the efficacy and safety profile of apatinib monotherapy, or combined with chemotherapy or endothelial growth factor receptor (EGFR)-TKI in heavily pretreated non-small cell lung cancer (NSCLC) patients with brain metastases. We performed a retrospective analysis for relapsed NSCLC patients with brain metastases from our institute, who received apatinib (250 mg or 500 mg p.o. qd) monotherapy, or combination with EGFR-TKI or chemotherapy as second or more line systemic therapy until disease progression or unacceptable toxicity occurred. The objective response rate (ORR), disease control rate (DCR), median progression-free survival (mPFS), median overall survival (mOS), and safety were analyzed. A total of 26 eligible patients were included: 24 patients diagnosed with adenocarcinoma, 2 with squamous carcinoma, and 14 patients harboring EGFR sensitizing mutations. The mPFS and mOS were 4.93 (range, 0.27–32.91; 95% CI 3.64–6.22) and 14.70 (range, 0.27–32.91; 95% CI 0.27–43.60) months for the whole group. The ORR and DCR were 7.7% (2/26) and 69.2% (18/26) for the entire lesions, and 7.7% (2/26) and 79.6% (20/26) for brain metastases, respectively. Compared with patients who received apatinib monotherapy, patients who received apatinib combination treatment had more favorable mPFS (11.77 vs. 2.27 months, p < 0.05) and mOS (24.03 vs. 6.07 months, p < 0.05). Treatment-related toxicities were tolerable including grade 1/2 hypertension, hand-and-foot syndrome, fatigue, nausea, liver dysfunction, myelosuppression, skin rash, and palpitation. In conclusion, apatinib exhibited high activity and good tolerance for NSCLC patients with brain metastasis, and it might become a potential choice for metastatic brain tumors in NSCLC patients.

Abstract
BACKGROUND AND OBJECTIVE The brain is an unusual site for distant metastases of differentiated thyroid carcinoma (DTC). The aim of this study was to document the prevalence of brain metastases from DTC at our institutions and to analyze the current therapies and the outcomes of these patients. METHODS We performed a retrospective chart review of patients with DTC and secondary neoplasia of the brain. RESULTS From 2002 to 2016, 9514 cases of thyroid cancer were evaluated across our institutions and 24 patients met our inclusion criteria, corresponding to a prevalence of 0.3% of patients with DTC. Fourteen (58.3%) were female and 10 (41.7%) were male. Fifteen patients had papillary thyroid cancer (PTC) (62.5%). Brain metastases were diagnosed 0 to 37 years (mean ± SD, 10.6 ± 10.4 years) after the initial diagnosis of thyroid cancer. Patients undergoing surgery had a median survival time longer than those that did not undergo surgery (27.3 months vs 6.8 months; P = 0.15). Patients who underwent stereotactic radiosurgery (SRS) had a median survival time longer than those that did not receive SRS (52.5 months vs 6.7 months; P = 0.11). Twelve patients (50%) were treated with tyrosine kinase inhibitors (TKIs), and they had a better survival than those who have not used a TKI (median survival time, 27.2 months vs 4.7 months; P < 0.05). CONCLUSION The prevalence of brain metastases of DTC in our institutions was 0.3% over 15 years. The median survival time after diagnosis of brain metastases was 19 months. In our study population, the use of TKI improved the survival rates.

Abstract
BACKGROUND Solitary intracranial metastases of differentiated thyroid carcinoma (DTC) are rare, and their management is still controversial. This research aimed to seek suitable therapeutic methods for this disease. METHODS We retrospectively studied 11 pathologically confirmed cases of solitary intracranial metastases of DTC in a single institution from January 2000 to December 2016 and systematically reviewed 52 cases of this disease out of 416 cases described in the literature on PubMed. These 63 cases were analyzed by Kaplan-Meier analysis, Cox regression analysis, and post-hoc test. RESULTS The diameters of intracranial metastases in all 63 cases were greater than 2 cm. Lung metastases (P = 0.000) and neurosurgery (P = 0.014) were 2 independent prognostic factors of this disease. Only neurosurgery (P = 0.05) was an independent prognostic factor in the patients with lung metastases, and neurosurgery (P = 0.044) and whole brain radiotherapy (WBRT) (P = 0.041) were 2 independent factors in the patients without lung metastases. Longer overall survival (OS) was achieved in the gross total removal (GTR) and subtotal removal (STR) groups than in the no neurosurgery group (P = 0.015, P = 0.084, respectively), and there was no significance between the GTR and STR groups (P = 0.918). CONCLUSION The patients without lung metastases had a better prognosis than did the patients with lung metastases. Neurosurgery could obviously improve the prognosis, and if possible, GTR of metastases was supposed to be achieved; STR could be considered. WBRT was a suitable method after neurosurgery in the patients without lung metastases but could not prolong OS in the patients with lung metastases.

Abstract
INTRODUCTION Metastases to central nervous system (M1-CNS) are rarely reported in thyroid cancer (TC) patients. We aimed to characterize patients with M1-CNS from TC followed in our department. METHODS Review of the medical records of 27 patients with TC-related M1-CNS. RESULTS Mean age at TC diagnosis was 56.9 ± 19.1 years. Papillary TC (55.6%) was the commonest histological type, followed by poorly differentiated (18.5%), medullary (11.1%), follicular (7.4%) and Hürthle cell (7.4%) carcinomas. Angioinvasion and extrathyroidal extension were observed in a high number of patients. At M1-CNS diagnosis, other distant metastases were already present in 77.8% of the patients. Treatment directed to M1-CNS was offered to 20 (74%) patients: 1 was submitted to surgery, 18 to radiotherapy (either whole-brain radiotherapy or stereotaxic radiosurgery or both) and 4 to surgery and radiotherapy. Four patients received cytotoxic chemotherapy and one was submitted to 131I. Median survival since M1-CNS detection was 5.0 months. The only factor associated with better survival was surgery to brain metastases (P = 0.012). CONCLUSIONS The management of these patients is very challenging given the inexistence of effective treatments, except for brain surgery in selected cases.

Abstract
Thyroid cancer is a common malignancy of endocrine system, and has now become the fastest increasing cancer among all the malignancies. The development, progression, invasion, and metastasis are closely associated with multiple signaling pathways and the functions of related molecules, such as Src, Janus kinase (JAK)-signal transducers and activators of transcription (STAT), mitogen-activated protein kinase (MAPK), phosphoinositide 3-kinase (PI3K)/Akt, NF-κB, thyroid stimulating hormone receptor (TSHR), Wnt-β-catenin and Notch signaling pathways. Each of the signaling pathways could exert its function singly or through network with other pathways. These pathways could cooperate, promote, antagonize, or interact with each other to form a complex network for the regulation. Dysfunction of this network could increase the development, progression, invasion, and metastasis of thyroid cancer. Inoperable thyroid cancer still has a poor prognosis. However, signaling pathway-related targeted therapies offer the hope of longer quality of meaningful life for this small group of patients. Signaling pathway-related targets provide unprecedented opportunities for further research and clinical development of novel treatment strategies for this cancer. In the present work, the advances in these signaling pathways and targeted treatments of thyroid cancer were reviewed.

Abstract
UNLABELLED Brain metastases are the most common intracranial malignancy. Many approaches, including radiation therapy, surgery, and cytotoxic chemotherapy, have been used to treat patients with brain metastases depending on the patient's disease burden and symptoms. However, stereotactic surgery (SRS) has revolutionized local treatment of brain metastases. Likewise, targeted therapies, including small-molecule inhibitors and monoclonal antibodies that target cancer cell metabolism or angiogenesis, have transformed managing systemic disease. Prospective data on combining these treatments for synergistic effect are limited, but early data show favorable safety and efficacy profiles. The combination of SRS and targeted therapy will further individualize treatment, potentially obviating the need for cytotoxic chemotherapy or whole-brain radiation. There is a great need to pursue research into these exciting modalities and novel combinations to further improve the treatment of patients with brain metastases. This article discusses reported and ongoing clinical trials assessing the safety and efficacy of targeted therapy during SRS. IMPLICATIONS FOR PRACTICE Treatment of patients with brain metastases requires a multidisciplinary approach. Stereotactic radiosurgery is increasingly used in the upfront setting to treat new brain metastasis. Targeted therapies have revolutionized systemic treatment of many malignancies and may sometimes be used as initial treatment in metastatic patients. There is sparse literature regarding safety and efficacy of combining these two treatment modalities. This article summarizes the supporting literature and highlights ongoing clinical trials in combining radiosurgery with targeted therapy.

Abstract
The purpose of our review is to summarize the clinical activity of oral targeted agents against brain metastases. This includes BRAF inhibitors (dabrafenib and vemurafenib), human epidermal growth factor receptor inhibitors (lapatinib, gefitinib, erlotinib, and afatinib), multi-kinase angiogenesis inhibitors (sorafenib, sunitinib, pazopanib, and vandetanib), and ALK/c-MET (crizotinib) and ALK/IGF-1 (ceritinib) inhibitors. Effective systemic therapies are needed for long-term benefit in brain metastases and documentation of intracranial activity for many therapies is poor. Our review provides a summary of the literature with pertinent data for clinicians. This is needed as subjects with brain metastases are often prevented from enrolling in clinical trials and investigations focused on systemic therapies for brain metastases are rare.

Abstract
INTRODUCTION Sorafenib (Nexavar) is an oral multi-kinase inhibitor targeting B-type Raf kinase (BRAF) (both wild type and BRAF(V600E)), VEGFR1, VEGFR2, VEGFR3, PDGFRβ and RET (also RET/PTC) influencing both differentiated thyroid cancer (DTC) cell proliferation and angiogenesis. AREAS COVERED Encouraging results achieved in numerous Phase II trials were confirmed in a Phase III study conducted in radioiodine-refractory DTC. Sorafenib compared to placebo significantly prolongs progression-free survival, 10.8 versus 5.8 months, respectively. However, its administration resulted mainly in disease stabilization. No complete remission was obtained in any study. Beneficial effects were also demonstrated for medullary and anaplastic thyroid cancer; however further studies fulfilling evidence based medicine criteria are necessary. Its toxicity profile is convergent with other VEGFR inhibitors. The most common treatment-related side-effects involve skin toxicity (predominantly hand-foot skin reaction, different rashes and alopecia), gastrointestinal disturbances (diarrhea, abdominal pain), constitutional adverse reactions (anorexia, weight loss, fatigue) and hypertension. Although most adverse reactions are manageable, > 50% of patients required dose reduction. EXPERT OPINION Sorafenib constitutes the first line treatment option in advanced, radioiodine-refractory DTC. However, there are still no data on its efficacy in patients progressed after another tyrosine kinase inhibitor. Other applications of the drug, such as use as adjuvant therapy to 131-I treatment, requires further studies.

Abstract
Thyroid cancer is the most common endocrine malignancy, and its incidence is increasing. Standard therapy for most patients with localized differentiated thyroid cancer (DTC) includes surgery, radioactive iodine, and thyroid hormone replacement. A minority of thyroid cancer patients requires systemic therapy for metastatic disease. Patients with metastatic DTC do not usually benefit from traditional cytotoxic chemotherapy. In this review, we describe newly developed small-molecule tyrosine kinase inhibitors (TKIs) that are being actively tested and used in the management of advanced thyroid cancer. The use of TKIs as a form of molecular targeted therapy is evolving based on understanding of the pathways involved in DTC. Disrupting tumor vascular supply by targeting vascular endothelial growth factor receptor signaling is the most commonly used approach to treat advanced/metastatic DTC. Other mechanisms include targeting BRAF, MAPK/ERK kinase, or mammalian target of rapamycin signaling. Although TKIs appear to have superior efficacy compared to cytotoxic chemotherapy, they can cause substantial adverse effects; symptomatic management of adverse effects, dose adjustment, or cessation of therapy may be required.

Abstract
Sorafenib (Nexavar) is a multikinase inhibitor, which has demonstrated both anti-proliferative and anti-angiogenic properties in vitro and in vivo, inhibiting the activity of targets present in the tumor cell [c-RAF (proto-oncogene serine/threonine-protein kinase), BRAF, (V600E)BRAF, c-KIT, and FMS-like tyrosine kinase 3] and in tumor vessels (c-RAF, vascular endothelial growth factor receptor-2, vascular endothelial growth factor receptor-3, and platelet-derived growth factor receptor β). For several years, sorafenib has been approved for the treatment of hepatocellular carcinoma and advanced renal cell carcinoma. After previous studies showing that sorafenib was able to inhibit oncogenic RET mutants, (V600E)BRAF, and angiogenesis and growth of orthotopic anaplastic thyroid cancer xenografts in nude mice, some clinical trials demonstrated the effectiveness of sorafenib in advanced thyroid cancer. Currently, the evaluation of the clinical safety and efficacy of sorafenib for the treatment of advanced thyroid cancer is ongoing. This article reviews the anti-neoplastic effect of sorafenib in thyroid cancer. Several completed (or ongoing) studies have evaluated the long-term efficacy and tolerability of sorafenib in patients with papillary and medullary aggressive thyroid cancer. The results suggest that sorafenib is a promising therapeutic option in patients with advanced thyroid cancer that is not responsive to traditional therapeutic strategies.

Abstract
BACKGROUND Malignant pleural effusion (MPE) caused by metastatic differentiated thyroid carcinoma (DTC) is usually associated with a rapid fatal outcome and should be recognized as a grim prognostic indicator. A standard therapeutic strategy has not been established for this situation. Here, we report a radioiodine-refractory follicular thyroid carcinoma (FTC) patient in whom a notable decrease of MPE was achieved after treatment with sorafenib. PATIENT FINDINGS A 50-year-old patient underwent a total thyroidectomy and resection of recurrence for poorly differentiated FTC followed by radioiodine therapy with a negative whole body scan. One year later, dissection of the inferior lobe of the left lung was performed because two fluorodeoxyglucose-avid nodules were identified; pathological examination revealed a metastatic poorly differentiated FTC. Half a year later, he was referred to our clinic because of cough, thoracic pain, nausea, and loss of appetite. Chest computed tomography showed right lung multiple nodules, left pleural effusion, and left lung collapse with left-sided pleural thickening. We treated him with sorafenib. Clinical and radiographic assessments were performed periodically. SUMMARY Symptoms and signs improved dramatically and continuously after initiation of sorafenib treatment. A duration of more than 12 weeks of apparent reduction of pleural effusion was achieved, which was confirmed by consecutive computed tomography examinations. Despite grade 1 alopecia, no other obvious treatment-related adverse events occurred. CONCLUSIONS As a grim prognostic indicator for patients with DTC, no standard treatment recommendation for pleural effusion exists. Targeted therapy using sorafenib may be an effective therapeutic strategy in the treatment of MPE caused by FTC.

Abstract
Thyroid cancer (TC) is the most common endocrine malignancy with steadily increasing incidence over the past few decades. Although standard strategies for the management of TC offer optimal outcomes in TC patients with favorable histological types at early stage, challenges arising from diagnosis and therapy still exist during clinical practice. A number of genetic alterations have been described in thyroid cancer, which provides an unprecedented opportunity for the identification of novel diagnostic and prognostic molecular markers as well as novel therapeutic targets. Molecular-targeted therapies, which have been investigated recently with increasing success, may prove to be a breakthrough in patients with advanced, radioiodine-refractory thyroid cancers. This review summarizes the latest progression in molecular diagnosis and targeted therapy of TC.

Abstract
Thyroid carcinoma is the most common endocrine malignancy, and although the disease generally has an excellent prognosis, therapeutic options are limited for patients not cured by surgery and radioiodine. Thyroid carcinomas commonly contain one of a small number of recurrent genetic mutations. The identification and study of these mutations has led to a deeper understanding of the pathophysiology of this disease and is providing new approaches to diagnosis and therapy. Papillary thyroid carcinomas usually contain an activating mutation in the RAS cascade, most commonly in BRAF and less commonly in RAS itself or through gene fusions that activate RET. A chromosomal translocation that results in production of a PAX8-PPARG fusion protein is found in follicular carcinomas. Anaplastic carcinomas may contain some of the above changes as well as additional mutations. Therapies that are targeted to these mutations are being used in patient care and clinical trials.

Abstract
BACKGROUND Brain metastases arise in roughly 0.9% of all cases of differentiated thyroid cancer. The median survival of adult patients with thyroid carcinoma that has metastasized to the brain is less than one year. Radioactive iodine treatment is only rarely given because its efficacy is not documented. In children, the situation may be different. METHOD In 2005, a 15-year-old girl underwent thyroidectomy, and an oxyphilic variant of papillary thyroid carcinoma was found in ectopic thyroid tissue. The patient underwent oral, high-dose radioactive iodine treatment. The post-therapeutic I-131 whole-body scan revealed multiple metastases in the skeleton, lungs, and the soft tissues, along with physiological uptake of the residual thyroid tissue. Magnetic resonance imaging of the head revealed two brain metastases. RESULTS When the initial treatment was completed, additional age-adapted high-dose radioactive iodine treatment was given, up to a total activity level of 35 GBq. There followed a complete remission of all metastases in the brain, bones, lungs, and soft tissues. Computed tomography of the chest revealed stable residuals. Over the ensuing 7.5 years of follow-up, the thyroglobulin values steadily declined to less than 2 ng/mL. The patient was asymptomatic at her last follow-up in May 2013. She did not develop any delayed reaction to high-dose radioactive iodine treatment (in particular, she did not develop leukemia or any other secondary malignancy). She remained fertile: after completion of the treatment, she had two healthy children. CONCLUSION In this patient with multifocal thyroid carcinoma, a rare entity, radioactive iodine treatment was successful as the single treatment. This case illustrates the point that a given therapeutic modality might succeed in an individual case despite a total or near-total lack of efficacy for most patients in the same situation.

RECIST 1.1 and serum thyroglobulin measurements in the evaluation of responses to sorafenib in patients with radioactive iodine-refractory differentiated thyroid carcinoma.

Abstract
The present study was designed to investigate the association between response evaluation criteria in solid tumors (RECIST) 1.1 and 1.0, and to explore the utility of thyroglobulin (Tg) measurements in assessing tumor responses to sorafenib in patients with radioactive iodine (RAI)-refractory differentiated thyroid carcinoma (DTC). In total, 23 patients with RAI-refractory DTC were enrolled. A comparison of RECIST 1.1 and 1.0 was performed in all patients with measurable disease. Following the exclusion of patients who were positive for anti-Tg antibody, the correlation between RECIST 1.1 and Tg was investigated in patients with measurable disease, and the concordance of the change in Tg between these patients and the patients with non-measurable disease only was analyzed over time. Tumor responses, assessed by RECIST 1.1 and 1.0, were concordant in 96% of the 23 records. However, the number of target lesions, according to RECIST 1.1, was significantly lower than when using RECIST 1.0. Progressive disease (PD) was identified in one of the five patients who underwent fluorodeoxyglucose-positron emission tomography (FDG-PET)/computed tomography (CT) scanning. A correlation between the Tg levels and the sum of the diameters of the target lesions was verified, with the percentage decrease in Tg levels significantly greater than that in the radiograph, demonstrating shrinkage. Furthermore, the percentage change in Tg levels was consistent between the patients with measurable disease and the subjects with non-measurable disease only. In conclusion, in patients with RAI-refractory DTC, RECIST 1.1 is highly concordant with RECIST 1.0 in the assessment of responses to sorafenib treatment, with the advantage of simplified procedures and the complementary use of FDG-PET. Tg measurements, in concordance with RECIST 1.1, are valuable in the evaluation of tumor responses.

Abstract
Thyroid nodules are frequent findings, especially when sensitive imaging methods are used. Although thyroid cancer is relatively rare, its incidence is increasing, particularly in terms of small tumors, which have an uncertain clinical relevance. Most patients with differentiated thyroid cancer exhibit satisfactory clinical outcomes when treatment is appropriate, and their mortality rate is similar to that of the overall population. However, relapse occurs in a considerable fraction of these patients, and some patients stop responding to conventional treatment and eventually die from their disease. Therefore, the challenge is how to identify the individuals who require more aggressive disease management while sparing the majority of patients from unnecessary treatments and procedures. We have updated the Brazilian Consensus that was published in 2007, emphasizing the diagnostic and therapeutic advances that the participants, representing several Brazilian university centers, consider most relevant in clinical practice. The formulation of the present guidelines was based on the participants' experience and a review of the relevant literature.

Abstract
Brain metastases (BM) are the most common intracranial tumors and their incidence is increasing. Untreated brain metastases are associated with a poor prognosis and a poor performance status. Metastasis development involves the migration of a cancer cell from the bulk tumor into the surrounding tissue, extravasation from the blood into tissue elsewhere in the body, and formation of a secondary tumor. In the recent past, important results have been obtained in the management of patients affected by BM, using surgery, radiation therapy, or both. Conventional chemotherapies have generally produced disappointing results, possibly due to their limited ability to penetrate the blood-brain barrier. The advent of new technologies has led to the discovery of novel molecules and pathways that have better depicted the metastatic process. Targeted therapies such as bevacizumab, erlotinib, gefitinib, sunitinib and sorafenib, are all licensed and have demonstrated improved survival in patients with metastatic disease. In this review, we will report current data on targeted therapies. A brief review about brain metastatic process will be also presented.
