In the reported case 74 malignant metastases were found in the brain. The primary tumour was a bronchogenic carcinoma. The clinical symptoms were scant and were restricted mainly to those produced by involvement of the pons without evidence of intracranial hypertension. In the discussion the only relative value of laboratory investigations is stressed, including computerized tomography. The case deserves publication in view of rare occurrence of such oligosymptomatic course despite a high number of metastases.

Purpose: Mammary carcinoma is comprised heterogeneous groups of cells with different metastatic potential. 4T1 mammary carcinoma cells metastasized to heart (4THM), liver (4TLM) and brain (4TBM) and demonstrate cancer-stem cell phenotype. Using these cancer cells we found thatTGF-β is the top upstream regulator of metastatic process.

Cerebral arteriovenous malformations (AVMs) are tangles of abnormal vessels with early arteriovenous (AV) shunting that can lead to intracerebral hemorrhage, seizures, neurologic deficit, or headache. To date, only a few cases of carcinomas metastasizing to pre-existing cerebral AVMs have been reported in the literature. However, renal clear cell carcinoma (RCC) brain metastases that exhibit early AV shunting, where AVM pathology is not present, are extremely rare.

Selective poly(ADP-ribose) polymerase 1 (PARP1) inhibitors not only exhibit antitumor efficacy but also offer the potential to mitigate the toxicities typically associated with broader PARP inhibition. In this study, we designed and synthesized a series of small molecules targeting highly selective PARP1 inhibitors. Among these, demonstrated excellent selectivity to PARP1 along with the capability to effectively cross the blood-brain barrier (BBB).

Background: Patients with non-small cell lung cancer (NSCLC) are prone to developing brain metastases (BMs), particularly those with epidermal growth factor receptor (EGFR) mutations. In clinical practice, treatment-naïve EGFR-mutant NSCLC patients with asymptomatic BMs tend to choose EGFR-tyrosine kinase inhibitors (TKIs) as first-line therapy and defer intracranial radiotherapy (RT). However, the effectiveness of upfront intracranial RT remains unclear.

Background: Cutaneous melanoma is the leading cause of death from cutaneous malignancy and tends to metastasize lymphatically and hematogenously to the lung, liver, brain, and bone; it is a rare source of metastatic disease to the eye. Herein we provide a case report of cutaneous melanoma metastatic to the ciliary body and choroid involving clinical examination, slit lamp photography, and B-scan ultrasonography.
Result: A 55-year-old female with known metastatic cutaneous melanoma presented with pain, a large ciliochoroidal mass, visual decline, and diffuse intraocular inflammation.
