A multicenter cohort study of osimertinib compared with afatinib as first-line treatment for EGFR-mutated non-small-cell lung cancer from practical dataset: CJLSG1903.

ESMO Open 2021 May 10;6(3):100115. Epub 2021 May 10.

Department of Respiratory Medicine, Matsunami General Hospital, Kasamatsu, Gifu, Japan.

Background: FLAURA, the prospective trial of osimertinib as a first-line therapy compared with first-generation epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs), did not show superior survival benefit for osimertinib in either the subgroup of Asians or the subgroup with the L858R mutation. In addition, the superiority of osimertinib compared with second-generation EGFR-TKI is thus far unclear.

Patients And Methods: We reviewed the clinical data of all consecutive patients who were treated with osimertinib or afatinib as first-line therapy between May 2016 and October 2019 from 15 institutions in Japan. Read More

Department of Biological Sciences, Korea Advanced Institute of Science and Technology (KAIST), Daejeon, South Korea.

Owing to increased awareness of the importance of mammogram and advances in surgical technology, survival rate of patients with primary breast cancer has dramatically increased. Despite all these advances in breast cancer treatment, there are no currently available treatments for this disease once it metastasizes to distant organs including bones, lungs, brain, and liver. This is mainly attributed to the complexity of metastatic process. Read More

Phospholipase Signaling in Breast Cancer.

Adv Exp Med Biol 2021 ;1187:23-52

School of Life Sciences, Ulsan National Institute of Science and Technology, Ulsan, Republic of Korea.

Breast cancer progression results from subversion of multiple intra- or intercellular signaling pathways in normal mammary tissues and their microenvironment, which have an impact on cell differentiation, proliferation, migration, and angiogenesis. Phospholipases (PLC, PLD and PLA) are essential mediators of intra- and intercellular signaling. They hydrolyze phospholipids, which are major components of cell membrane that can generate many bioactive lipid mediators, such as diacylglycerol, phosphatidic acid, lysophosphatidic acid, and arachidonic acid.

Multifunctional Liposomes Enable Active Targeting and Twinfilin 1 Silencing to Reverse Paclitaxel Resistance in Brain Metastatic Breast Cancer.

ACS Appl Mater Interfaces 2021 May 13. Epub 2021 May 13.

Jiangsu Key Laboratory of Molecular and Functional Imaging, Zhongda Hospital, Medical School, Southeast University, Nanjing 210009, People's Republic of China.

Paclitaxel (PTX) is a first-line chemotherapeutic drug for breast cancer, but PTX resistance often occurs in metastatic breast cancer. In addition, due to the poor targeting of chemotherapeutic drugs and the presence of the blood-brain barrier (BBB), it is hard to effectively treat brain metastatic breast cancer using paclitaxel. Thus, it is urgent to develop an effective drug delivery system for the treatment of brain metastatic breast cancer. Read More

Lasofoxifene as a potential treatment for therapy-resistant ER-positive metastatic breast cancer.

Breast Cancer Res 2021 May 12;23(1):54. Epub 2021 May 12.

The Ben May Department for Cancer Research, The University of Chicago, 929 East 57th Street, GCIS W421C, Chicago, IL, 60637, USA.

Background: Endocrine therapy remains the mainstay of treatment for estrogen receptor-positive (ER+) breast cancer. Constitutively active mutations in the ligand binding domain of ERα render tumors resistant to endocrine agents. Breast cancers with the two most common ERα mutations, Y537S and D538G, have low sensitivity to fulvestrant inhibition, a typical second-line endocrine therapy. Read More

Thorny ground, rocky soil: tissue-specific mechanisms of tumor dormancy and relapse.

Semin Cancer Biol 2021 May 9. Epub 2021 May 9.

Public Health Sciences Division/Translational Research Program, Fred Hutchinson Cancer Research Center, Seattle, WA, USA; Human Biology Division, Fred Hutchinson Cancer Research Center, Seattle, WA, USA. Electronic address:

Disseminated tumor cells (DTCs) spread systemically yet distinct patterns of metastasis indicate a range of tissue susceptibility to metastatic colonization. Distinctions between permissive and suppressive tissues are still being elucidated at cellular and molecular levels. Although there is a growing appreciation for the role of the microenvironment in regulating metastatic success, we have a limited understanding of how diverse tissues regulate DTC dormancy, the state of reversible quiescence and subsequent awakening thought to contribute to delayed relapse.

- Irmandade da Santa Casa de Misericórdia de São Paulo, Neurocirurgia - ISCMSP, SP, Brasil.

The anesthesia for awake craniotomy (AC) is a consecrated anesthetic technique that has been perfected over the years. Initially used to map epileptic foci, it later became the standard technique for the removal of glial neoplasms in eloquent brain areas. We present an AC anesthesia technique consisting of three primordial times, called awake-asleep-awake, and their respective particularities, as well as delve into the anesthetic medications used.

Limited brain metastases: a narrative review.

Ann Palliat Med 2021 Apr 26. Epub 2021 Apr 26.

Department of Radiation Oncology, University Hospitals Cleveland Medical Center, Cleveland, OH, USA; Case Western Reserve University School of Medicine, Cleveland, OH, USA.

Limited brain metastases refer to an oligometastatic state in the brain for which focal therapy with stereotactic radiosurgery (SRS) is appropriate. The definition of what is considered "limited" for brain metastases, however, is not well defined. Multiple recent randomized trials show that metastasis-directed therapy with surgery or stereotactic radiation can prolong survival for patients with 1-5 metastases from various primary tumors, but patients with untreated brain metastases were largely excluded from these trials.

A non-small cell lung cancer (NSCLC) patient with leptomeningeal metastasis harboring rare epidermal growth factor receptor (EGFR) mutations G719S and L861Q benefited from doubling dosage of osimertinib: a case report.

Ann Palliat Med 2021 May 8. Epub 2021 May 8.

Department of Neuro-Oncology, Guangdong Sanjiu Brain Hospital, Guangzhou, China.

Leptomeningeal metastasis (LM) is a rare but lethal complication of advanced non-small cell lung cancer (NSCLC) that has a devastating impact on patient survival and quality of life. Osimertinib, an irreversible tyrosine kinase inhibitor, is approved as a therapy for advanced NSCLC with epidermal growth factor receptor (EGFR) mutation. However, the efficacy and optimal dosage of osimertinib in the treatment of NSCLC patients with LM who harbor uncommon EGFR mutations have yet to be fully investigated. Read More

Co-Occurrence Conundrum: Brain Metastases from Lung Adenocarcinoma, Radiation Necrosis, and Gliosarcoma.

Case Rep Oncol 2021 Jan-Apr;14(1):487-492. Epub 2021 Mar 18.

Department of Radiation Oncology, Winship Cancer Institute of Emory University, Atlanta, Georgia, USA.

Non-small cell lung cancer (NSCLC) commonly presents with metastasis to the brain. When brain metastases are treated with stereotactic radiosurgery (SRS), longitudinal imaging to monitor treatment response may identify radiation necrosis, metastasis progression, and/or another primary brain malignancy. A 60-year-old female with metastatic NSCLC involving the brain underwent treatment with systemic therapy and SRS. Read More

Peripheral-specific Y1 receptor antagonism increases thermogenesis and protects against diet-induced obesity.

Nat Commun 2021 May 11;12(1):2622. Epub 2021 May 11.

Neuroscience Division, Garvan Institute of Medical Research, St Vincent's Hospital, Sydney, NSW, Australia.

Obesity is caused by an imbalance between food intake and energy expenditure (EE). Here we identify a conserved pathway that links signalling through peripheral Y1 receptors (Y1R) to the control of EE. Selective antagonism of peripheral Y1R, via the non-brain penetrable antagonist BIBO3304, leads to a significant reduction in body weight gain due to enhanced EE thereby reducing fat mass. Read More
