OBJECTIVE: Neurocognitive function is of great importance in patients with brain tumors. Even patients in good neurological condition may suffer from neurocognitive dysfunction that affects their daily living. The purpose of the present study was to identify risk factors for neurocognitive dysfunction in patients suffering from common supratentorial brain tumors with minor neurological deficits. METHODS: A prospective study evaluating neurocognitive dysfunction in patients with a newly-diagnosed brain tumor in good neurological condition was performed at a major German academic institution...

We describe a case of testicular tumor with multiple metastasis to the lung,retoroperitoneal lymph node, and brain. After chemotherapy the retroperitoneal lymph node and brain metastasis disappeared,but the multiple pulmonary metastases but not disappear,although they were reduced in size. Since the human chorionic gonadotoropin (HCG) was persistently dected at a low level,we performed a testosterone tolerance test. The HCG level became undetectable for a while,but was detected at a low level again. Then the patient underwent residual tumor removal of some of the residual pulmonary disease,which was diagnosed as tumor necrosis...

BACKGROUND: Given the neurological morbidity and poor prognosis associated with brain metastases, it is critical to deliver appropriate therapy while remaining mindful of patient quality of life (QOL). For many patients, stereotactic radiosurgery (SRS) effectively controls intracranial disease, but QOL outcomes have not been characterized. OBJECTIVE: To determine the effect of number of brain metastases upon QOL preservation following SRS. METHODS: The EuroQol 5 Dimensions questionnaire (EQ-5D) and Patient Health Questionnaire 9 instruments were prospectively collected from a cohort of patients undergoing SRS for brain metastasis between 2008 and 2015...

BACKGROUND: The metastases of a primary lung cancer over the thyroid gland are extremely rare. We report on an unusual presentation of thyroid metastasis of lung cancer in order to improve the management of similar cases. CASE PRESENTATION: Three years ago, a Moroccan male 59-year-old was admitted for dyspnea, dry cough, and chest pain. He had smoked about 30 cigarette packs a year. Clinical examination revealed a right thyroid nodule. Chest and neck computed tomography (CT) scan showed a proximal left tumor in contact with the pulmonary artery and revealed a suspected nodule in the right lobe of the thyroid with homolateral neck node...

Hepatocellular adenoma (HCA) is a rare benign liver tumor, predominantly seen in young women. Its major complications are malignant transformation, spontaneous hemorrhage, and rupture. We describe a case of a young female with no underlying liver disease who presented with acute abdominal pain and was found to have a 17 cm heterogeneous mass in the left lobe of the liver. She underwent left hepatectomy and pathology revealed a 14 cm moderately differentiated hepatocellular carcinoma (HCC) arising in a shell of a HCA...

Eleated expression of NIMA-related kinase 2 (NEK2) was frequently observed in a variety of malignant cancers, and it appears to be involved in the initiation, maintenance, progression, metastasis of cancer and is positively associated with poor prognosis. We sought to investigate NEK2 expression and its predictive roles in malignant gliomas, and study the correlation of NEK2 protein expression with proliferation, clinical parameters, overall survival and some other parameters. We investigate NEK2 protein expression in 99 samples of malignant gliomas, including 35 WHO grade II, 22 grade III, and 42 grade IV gliomas, by immunohistochemistry and western blot (n = 50)...

Long planning time in volumetric-modulated arc stereotactic radiotherapy (VMA-SRT) cases can limit its clinical efficiency and use. A vector model could retrieve previously successful radiotherapy cases that share various common anatomic features with the current case. The prsent study aimed to develop a vector model that could reduce planning time by applying the optimization parameters from those retrieved reference cases. Thirty-six VMA-SRT cases of brain metastasis (gender, male [n = 23], female [n = 13]; age range, 32 to 81 years old) were collected and used as a reference database...

Prothrombin and its active derivative thrombin are key members of the coagulation system. The only site of extra-hepatic thrombin expression is the central nervous system (CNS), where it is involved in brain development, protection, and regeneration. Thrombin affects various degenerative and ischemic CNS diseases like Alzheimer's, multiple sclerosis, cerebral ischemia, and hemorrhage in a dose dependent manner. Additionally, the association of thrombin with various malignancies has recently become evident. Thrombin facilitates the interaction between tumor cells with platelets, endothelial cells, and the adhesion to matrix proteins in various tumor types...

BACKGROUND Spinal cord ischemia is an uncommon event that is mainly caused by dissociation of the ascending aorta as a complication after aortic surgery. Spinal arteries can develop collateral circulation; therefore, the frequency of spinal infarction is about 1% of that in the brain. Few cases of spinal cord ischemia developing in the course of lung cancer have been reported. CASE REPORT We presented the case of a 56-year-old man with small cell lung carcinoma, cT4N2M1a (stage IV). He was treated with irradiation and 2 courses of platinum and etoposide combination chemotherapy...

The occurrence of multiple primary melanomas in a single individual is rare. Most commonly, malignant melanocytic lesions subsequent to the initial diagnosis of melanoma are secondary cutaneous metastases. We report a patient with gastrointestinal bleeding from gastric metastasis of cutaneous melanoma. During clinical evaluation and staging, we discovered a brain metastasis associated with 3 synchronous primary cutaneous melanomas. We suggest the research on the mutation in the cyclin-dependent kinase inhibitor 2A (CDKN2A) (INK4a) in such cases...

Gefitinib, erlotinib and afatinib are three widely used epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKIs) for treating advanced non-small cell lung cancer (NSCLC) with proven efficacy. We undertook a systematic review and meta-analysis to synthesize existing studies with direct comparisons of EGFR TKIs in NSCLC in terms of both efficacy and safety. Eight randomized trials and 82 cohort studies with a total of 17621 patients were included for analysis. Gefitinib and erlotinib demonstrated comparable effects on progression-free survival (hazard ratio [HR], 1...

A 61-year-old woman with an abnormal radiograph shadow in her anterior mediastinum was admitted to our hospital and underwent an extended thymectomy. The pathological diagnosis of the tumor was a non-papillary adenocarcinoma of the thymus in pathological stage IV b using the Masaoka classification owing to mediastinal lymph node metastasis. We found parasternal lymph node metastases 5 months after her first operation, and subsequently, she underwent surgery and adjuvant radiotherapy. We found systemic lymph node metastases and metastatic lesions in distant organs, including her lungs, brain, and kidney 27 months after her first operation...

Melanotic neuroectodermal tumor of infancy is a rare congenital pigmented neoplasm of neural crest origin, locally aggressive, growing rapidly and developing during the 1st year of life. It most commonly arises from the maxilla, cranial vault, and mandible. Occasionally, it exhibits malignant behavior with local lymph nodes involvement. Cases misdiagnosed and left untreated for a long time can present challenges due to the tumor mass and infiltration. In these cases, adjuvant chemotherapy can be extremely helpful before radical excision...

Metastasis, the spread and growth of malignant cells at secondary sites within a patient's body, accounts for > 90% of cancer-related mortality. Recently, impressive advances in novel therapies have dramatically prolonged survival and improved quality of life for many cancer patients. Sadly, incidence of brain metastatic recurrences is fast rising, and all current therapies are merely palliative. Hence, good experimental animal models are urgently needed to facilitate in-depth studies of the disease biology and to assess novel therapeutic regimens for preclinical evaluation...

Approximately half of surgically-treated patients with low-grade-glioma (LGG) suffer recurrence or metastasis. Currently there is no effective drug treatment. While the selective COX-2 inhibitor celecoxib showed anti-neoplastic activity against several malignant tumors, its effects against LGG remain to be elucidated. Ours is the first report that the expression level of COX-2 in brain tissue samples from patients with LGG and in LGG cell lines is higher than in the non-neoplastic region and in normal brain cells...
