A new study shows "How a Chemo Drug Can Help Cancer Spread from the Breast to the Lungs" . Really? How does that work? Why are they telling me now instead of before chemo?" Researchers at The Ohio State University studied the cascade of events that lead to metastatic cancer and found clues to why it happens, opening up the possibility of one day interfering with the medication's downsides while preserving its cancer-fighting properties in breast tissue.The front-line chemotherapy drug paclitaxel sets off a variety of molecular-level changes that allow breast cancer cells to escape from the tumor. At the same time, it creates an environment in the lung that is more hospitable to the cancer cells, facilitating the spread of the disease, the researchers found in a mouse model of breast cancer. "I know chemo drugs are strong which is why they are used to kill cancer cells. But this is just really bad. Why? Because the'other name for paclitaxel isTaxol. Which I had. Thanks for that push back on the cancer roller coaster. And then there is this little disclaimer at the bottom that's supposed to make us feel better." She said it's important to recognize that the cancer cells in the study's mouse model are very aggressive and that it would be interesting to test whether paclitaxel also enhances the escape of cancer cells at earlier stages in cancer progression.

ConclusionsA majority of IBC patients in our study presented with node-positive disease, and for those presenting with cN2-3 disease, more extensive axillary surgery is potentially associated with improved survival. For cN0 patients, however, more extensive axillary surgery was not associated with a survival benefit, suggesting an opportunity for more personalized care.

Authors: Batoo S, Bayraktar S, Al-Hattab E, Basu S, Okuno S, Glück S Abstract With the introduction of anthracycline-based regimens, 5-year survival rates have significantly improved in patients with early-stage breast cancer. With the addition of trastuzumab, a monoclonal antibody targeting the human epidermal growth factor receptor-2 (HER2), improvements in overall survival have been observed among patients with advanced HER2-positive disease. Subsequently, lapatinib, an orally bioavailable small molecule dual HER2- and EGFR/HER1-specific tyrosine kinase inhibitor, received Food and Drug Administration (FDA)...

Publication date: Available online 18 January 2020Source: Redox BiologyAuthor(s): Mohamad Assi, Suzanne Dufresne, Amélie RébillardAbstractIn this paper of the special issue dedicated for the Olympics 2020, we put the light on an exciting facet of exercise-oncology, which may still be unknown to some audience. Accumulating convincing evidences show that exercise reduces cancer progression and recurrence mainly in colon and breast cancer patients. Interestingly, the positive effects of exercise on cancer outcomes were mainly observed when patients practiced vigorous exercise of 6 METs or more. At the molecular ...

We describe the adaptation of a model-based design for identifying the maximum tolerated dose combination that efficiently moves from the initial phase in an advanced disease population to the second phase in the target population. Operating characteristics demonstrate the ability of the method to accurately predict true maximum tolerated dose combinations in a high percentage of trials with reasonable sample sizes, while treating participants at and around desirable combinations. The proposed design is a practical, early-phase, adaptive method for use with drug combination dose finding in the presence of shifting patient ...

CONCLUSION: SM bioenergetics and oxidative capacity in response to PFE are not impaired following anthracycline treatment. Abnormal SM composition (increased thigh and lower leg IMF-to-SM ratio) may be an important contributor to reduced peak VO2 during whole-body exercise among anthracycline-treated BC survivors. IMPLICATIONS FOR PRACTICE: Peak oxygen consumption (peak VO2 ) is reduced in breast cancer (BC) survivors and is prognostic of increased risk of cardiovascular disease-related and all-cause mortality. Results of this study demonstrated that in the presence of deficits in peak VO2 1 year after anthracycline t...

Abstract BACKGROUND: In the absence of randomized controlled trials, real-world evidence may aid practitioners in optimizing the selection of therapy for patients with cancer. The study's aim was to determine real-word use, as well as compare effectiveness, of single-agent and combination chemotherapy as palliative treatment for female patients with metastatic breast cancer (mBC). MATERIALS AND METHODS: Using administrative claims data from the Symphony Health's Integrated Oncology Dataverse, female patients with mBC treated with at least one chemotherapy-only treatment (COT) between January 1, 2013, and Dece...

We present the results of a phase I study of an oral selective gamma secretase (GS) inhibitor (critical to Notch signaling), RO4929097 in combination with neoadjuvant chemotherapy for operable triple negative breast cancer. The primary objective was to determine the maximum tolerated dose (MTD) of RO4929097. Secondary objectives were to determine real-time pharmacokinetics of RO4929097 and paclitaxel, safety and pathologic (pCR) complete response to study treatment. Eligible patients, initiated carboplatin at AUC 6 administered intravenously (IV) on day 1, weekly paclitaxel at 80  mg/m2 IV and RO4929097 10 mg dai...

Conclusions Sentinel lymph node identification using preoperative scintigraphy and intraoperative use of gamma probe seems to be a feasible and efficient method in terms of differentiating patients that require axillary lymph node dissection during breast cancer surgery, even when they have received neoadjuvant chemotherapy. Further large prospective studies allowing subgroup analyses are warranted.

This study was designed to investigate the role and therapeutic implications of miR-151-5p in breast cancer. The results of the present study revealed that miR-151-5p is significantly downregulated in breast cancer tissues and cell lines. Overexpression of miR-151-5p in SK-BR-3 and CAMA-1 cells inhibits their proliferation and colony formation. Wound heal and transwell assays showed that miR-151-5p inhibits the migration and invasion of the SK-BR-3 and CAMA-1 breast cancer cells. TargetScan analysis followed by the dual luciferase assay confirmed SOCS5 to be the target of miR-151-5p in breast cancer. The expression of SOCS...

AbstractBackgroundThe aim of the study was to develop a deep learning (DL) algorithm to evaluate the pathological complete response (pCR) to neoadjuvant chemotherapy in breast cancer.MethodsA total of 302 breast cancer patients in this retrospective study were randomly divided into a training set (n =  244) and a validation set (n = 58). Tumor regions were manually delineated on each slice by two expert radiologists on enhanced T1 ‐weighted images. Pathological results were used as ground truth. Deep learning network contained five repetitions of convolution and max‐pooling layers and ended with three dense laye...
