The Promise of Immunotherapy for Breast Cancer Brain Metastases

AbstractPurpose of ReviewThe goal of our review is to describe the rationale for immunotherapy in the treatment of breast cancer brain metastases (BCBM), the current landscape of clinical trials for this disease process, and possible future directions based on anticipated results.Recent FindingsImmune checkpoint inhibition has shown efficacy in the treatment of several solid tumor brain metastases (i.e., melanoma and non-small cell lung cancer), but data specific to BCBM is relatively sparse. Preclinical studies in BCBM have illustrated a lower immune content in the brain microenvironment measured by tumor-infiltrating lymphocytes (TILs) in brain metastases compared to primary tumors. Yet, improved outcomes are associated with higher TIL content in the BCBM, and strategies to understand and alter the complex brain immune microenvironment are needed.Summary of FindingsBased on observations in the non-breast cancer setting and early results in advanced breast cancer, it is likely that novel, strategic combination immunotherapy strategies will be needed to yield meaningful outcomes for BCBM patients. Some exciting concepts underway include novel immunotherapy combinations, concurrent stereotactic radiosurgery, bi-specific antibody armed activated T cells, and HER2-chimeric antigen receptor T cells for leptomeningeal disease.

Authors: Cao M, Zhou M, Zhang J Abstract Patients with metastatic colorectal cancer (mCRC) beyond second line treatment have a poor prognosis. Regorafenib, TAS-102, fruquintinib, panitumumab and cetuximab are recommended single-agent chemotherapy regimens for patients exhibiting disease progression, this meta-analysis aimed to evaluate the efficacy and safety of these regimens in randomized controlled trials (RCTs). Eight RCTs with 3,832 cancer patients were included. Results showed that there was no significant difference in OS and PFS among the four drugs when comparing all patients or patients who have the KRAS ...

CONCLUSION: The best of our knowledge it is the third description of brachial plexus schwannoma associated with breast cancer and the first with a synchronous association. The knowledge of this pathology and its potential to alter treatment justify the reporting of the present case. PMID: 32083563 [PubMed - as supplied by publisher]

In this study, dosimeters were used to measure the testicular dose with and without testicular shielding to verify the effect of shielding. Anthropomorphic phantoms representing a human were used to estimate the doses absorbed in testicular and whole-body studies. The anthropomorphic phantom was irradiated according to the treatment protocol for colorectal cancer. Measurements were made using optically-stimulated luminescent dosimeters (OSLDs), composed of carbon-doped aluminum oxide, with characteristics suitable for radiotherapy dosimetry studies. A set of OSLDs was placed on a testicular phantom, attached to the lower e...

Authors: Herold A Abstract Hemorrhoidal disease is one of the most common illnesses in industrialized nations. Up to 70% of adults suffer from the disease once in their lifetime. This underlines the necessity and importance of knowing about the differential diagnosis of hemorrhoids. One can differentiate between differential diagnoses of symptoms (bleeding, pain, itching, tumor) and differential diagnoses of the phenotype findings (anal prolapse, mucosal prolapse and rectal prolapse, skin tags, hypertrophied anal papillae, condylomata acuminata, anal fissure, perianal venous thrombosis, anal cancer). PMID: 3207...

Authors: Hessam S, Bechara FG Abstract Hidradenitis suppurativa/acne inversa (HS/AI) is a chronic inflammatory skin disease. Several studies showed that perianal, perineal and gluteal involvement is more common in men. Axillary, submammary and inguinal localizations seem to be more prevalent in women. Involvement of the genitoanal region is associated with a higher reduced quality of live and sexual health compared to other locations. Moreover HS/AI in the genitoanal region can lead to serious complications. The knowledge of perianal fistula formation, pubogenital lymphedema and squamous cell carcinoma, w...

In spite of attempts to classifying breast cancer according to its histological and molecular properties, it is almost considered as a dilemma in treatment. Nowadays, public and medical attentions have primary focused on foods with anti-cancer properties to alleviate the cancer problems. Flavonoid components such as Quercetin (Qu) as dietary substances with high attention of ordinary people might provide potentia...

Authors: Han RH, Dunn GP, Chheda MG, Kim AH Abstract Metastases from melanoma, lung and breast cancer are among the most common causes of intracranial malignancy. Standard of care for brain metastases include a combination of surgical resection, stereotactic radiosurgery, and whole-brain radiation. However, evidence continues to accumulate regarding the efficacy of molecularly-targeted systemic treatments and immunotherapy. For non-small cell lung cancer (NSCLC), numerous clinical trials have demonstrated intracranial activity for inhibitors of EGFR and ALK. Patients with melanoma brain metastases may benefit from ...
