Background: The standard therapy for brain metastasis (BM) in non-small cell lung cancer (NSCLC) is radiation therapy (RT), although it is associated with complications such as leukoencephalopathy. In the current report, we retrospectively review data from eight patients who had NSCLC and harbored epidermal growth factor receptor (EGFR) mutations, and who were received erlotinib plus bevacizumab (E+B) as first-line therapy for BM. Methods: Patients were given E+B as first therapy for BM until August 2017 at our institution...

Most triple negative breast cancers (TNBCs) are aggressively metastatic with a high degree of intra-tumoral heterogeneity (ITH), but how ITH contributes to metastasis is unclear. Here, clonal dynamics during metastasis were studied in vivo using two patient-derived xenograft (PDX) models established from the treatment-naive primary breast tumors of TNBC patients diagnosed with synchronous metastasis. Genomic sequencing and high-complexity barcode-mediated clonal tracking reveal robust alterations in clonal architecture between primary tumors and corresponding metastases...

Long non-coding RNAs (lncRNAs) can serve as oncogenes and tumor suppressors and are involved in tumorigenesis and chemotherapy resistance. Brain cytoplasmic RNA 1 (BCYRN1), as a translational modulator, is an lncRNA comprised of 200 bases that plays an important role in multiple cancers. In this study, we explored the biological role of the lncRNA, BCYRN1, in the development of non-small cell lung cancer (NSCLC). We found that BCYRN1 was increased in NSCLC, and its downregulated expression could suppress NSCLC cell proliferation and cell cycle progression by inhibiting the Wnt/ β -catenin pathway...

BACKGROUND: Brain metastases (BM) are a common consequence of lung cancer and surgery is effective; however, the factors affecting survival after surgery are unclear. The aim of this study was to identify the outcomes and prognoses of post-metastasectomy patients with BM from non-small cell lung cancer (NSCLC) at a single institution over a 15-year period. METHODS: NSCLC patients who had undergone BM surgery were retrospectively identified. Survival was analyzed using the Kaplan-Meier curve, and univariate and multivariate factors associated with survival were identified using the Cox proportional hazards model...

Background: It was unclear whether breast cancer subtypes are associated with the risk of site-specific metastases. This study aimed to evaluate the relationship between molecular subtypes and distant metastatic sites and their prognostic significance. Methods: We identified 295,213 patients with invasive breast cancer from 2010 to 2014 using the Surveillance, Epidemiology and End Results database. Subtypes were classified into four categories: hormone receptor (HR+ )/human epidermal growth factor receptor 2 (HER2- ), HR+ /HER2+ , HR- /HER2+ , and triple-negative (HR- /HER2- )...

PURPOSE: Routine brain MRI surveillance frequently diagnoses small, asymptomatic brain metastases from non-small cell lung cancer (NSCLC) that are effectively treated with stereotactic radiosurgery (SRS). A subset of patients, however, may die prior to the onset of symptoms. This study identifies clinical features that distinguish neurologically-asymptomatic NSCLC brain metastases patients that die prior to routine 3 month follow-up after SRS. METHODS: Retrospective chart review from 2007 to 2017 identified 18 patients with neurologically-asymptomatic NSCLC brain metastases who died < 3 months after SRS...

Validated serum biomarkers for patients suffering from non-small cell lung cancer (NSCLC) brain metastasis are urgently needed for early diagnosis, treatment monitoring, and prognostic classification in daily clinical practice. Serum S100B was reported to be a marker of leaky blood-brain barrier (BBB), which was often caused by brain tumors. This study aimed to investigate the role of S100B in NSCLC brain metastasis. The results showed that serum S100B correlated significantly with NSCLC brain metastasis (P < 0...

CheckMate 141, an open-label, randomized phase III trial of nivolumab, indicated that treatment with nivolumab prolonged overall survival of patients with platinum-refractory, recurrent head and neck squamous cell carcinoma. Herein, we describe a case of brain metastasis of parotid carcinoma in which a good response was achieved after nivolumab treatment. The patient was a 67-year-old woman with parotid carcinoma (cT4bN0M0) who received induction chemotherapy followed by chemoradiation. Computed tomography and magnetic resonance imaging performed 10 weeks after the primary treatment revealed a residual tumor and brain and lung metastases...

Histotripsy fractionates tissue through a mechanical, non-invasive ultrasonic ablation process that precisely controls acoustic cavitation while utilizing real-time ultrasound (US) imaging guidance. This study investigates the potential, feasibility and tumor volume reduction effects of histotripsy for liver cancer ablation in a subcutaneous in vivo murine Hepatocellular Carcinoma (HCC) model. Hep3B tumors were generated in the right flanks of 14 NSG and 7 NOD-SCID mice. The mice were grouped as follows: A (acute, NSG with n=9 treatment and n=1 control), B (chronic, NSG with n=2 treatment and n=2 control) and C (chronic NODSCID, with n=6 treatment and n=1 control)...

Glioblastoma (GBM) is the most mortality brain cancer in the world. Due to high invasion and drug resistance cause the poor prognosis of GBM. Naringenin, an ingredient of citrus, exhibits many cellular functions such as antioxidant, anti-inflammation, and anticancer. Naringenin inhibits the migration of bladder and lung cancer via modulation of MMP-2 and/or MMP-9 activities, Naringenin inhibits migration and trigger apoptosis in gastric cancer cells through downregulation of AKT pathway. However, the effects of naringenin in GBM still remain to be elucidated...

PROTOCADHERIN 7 (PCDH7), a transmembrane receptor and member of the Cadherin superfamily, is frequently overexpressed in lung adenocarcinoma and is associated with poor clinical outcome. While PCDH7 was recently shown to promote transformation and facilitate brain metastasis in lung and breast cancers, decreased PCDH7 expression has also been documented in colorectal, gastric, and invasive bladder cancers. These data suggest context-dependent functions for PCDH7 in distinct tumor types. Given that PCDH7 is a potentially targetable molecule on the surface of cancer cells, further investigation of its role in tumorigenesis in vivo is needed to evaluate the therapeutic potential of its inhibition...

The most common sites of breast cancer metastasis are the bone, liver, lung and brain, while gastrointestinal metastasis from breast cancer is rare. We herein present the case of a 68-year-old woman who was admitted to our department with nausea and appetite loss. The patient's medical history included right mastectomy with sentinel lymph node biopsy 5 years earlier for invasive lobular carcinoma, measuring 6.2 cm in greatest diameter, without lymphovascular invasion. Two years after the surgery, the patient developed brain metastasis and underwent metastasectomy to control the neurological symptoms, including unsteadiness and asthenia...
