Differential benefit of metronomic chemotherapy among triple negative breast cancer subtypes treated in the IBCSG Trial 22-00
CONCLUSIONS: Our results show a differential benefit of low-dose CM therapy across different TNBC subtypes. Low-dose CM therapy could be considered as a potential immunomodulatory strategy for TNBC tumors with IM subtype in the early-disease setting.PMID:37733800 | DOI:10.1158/1078-0432.CCR-23-1267

Near-infrared spectral tomography for predicting residual cancer burden during early stage neoadjuvant chemotherapy for breast cancer
CONCLUSION: NIRST holds promise as a potential clinical tool that can be seamlessly integrated into existing clinical workflow within the infusion suite. By providing early assessment of RCB, NIRST has potential to improve breast cancer patient management strategies.PMID:37733788 | DOI:10.1158/1078-0432.CCR-23-1593

Brain-computer interface relieves chronic chemotherapy-induced peripheral neuropathy: A randomized, double-blind, placebo-controlled trial
CONCLUSIONS: BCI is a promising treatment for CIPN and may have a longer lasting effect than placebo (nonspecific BCI), which is an important consideration for long-term symptom relief. Although scientifically interesting, the ability to separate real from placebo treatment may not be as important as understanding the placebo effects differently from effects of the intervention.PLAIN LANGUAGE SUMMARY: Chemotherapy-induced nerve pain (neuropathy) can be disabling for cancer survivors; however, the way symptoms are felt depends on how the brain interprets the signals from nerves in the body. We determined that the perception...

Bone-Targeted Therapy Regimen and Skeletal-Related Events in Patients Surviving Longer Than 2 Years With Metastatic Breast Cancer and Bone Metastasis
CONCLUSION: Oncologists may have increased flexibility regarding the frequency of administration of BTT along with their choice of agent. Our study showed no significant difference in the prevention of overall SRE or development of BTT-associated harms between the BTT regimens evaluated.PMID:37735019 | DOI:10.1016/j.clbc.2023.08.008

Elevated profiles of peripheral Th22, Th17, Th2 cells, and decreased percentage of Th1 cells in breast cancer patients
CONCLUSION: Th22, Th17, Th1, and Th2 subsets may play an essential role in BC patients. Th22, Th17, Th1, and Th2 cells may have potential significance to be used as clinical markers in BC patients with different molecular classification. Th22 cells may have potential value in BC patients' outcomes prediction, providing clinical value.PMID:37732365 | DOI:10.1111/1759-7714.15119

Toxicological profiling of a de novo synthesized benzimidazole derivative with potent and selective proapoptotic potentials against breast cancer
This study aimed to investigate the toxicological profile of 1-(6-(1H-benzo[d]imidazole-2-yl)-2-methylpyridin-3-yl) ethanone (BMPE), both in vitro and in vivo. The proapoptotic/necrotic and cell cycle arrest potentials of BMPE were assessed in MCF-7 cell line. The in vivo toxicology was assessed in female Balb/c mice by repeated dosing of 5, 25, and 50 mg/kg for 21 consecutive days, then different biochemical, inflammatory, and oxidative markers were assessed in sera/tissue homogenates of treated animals. The new derivative showed a potent selective cytotoxicity against malignant cell lines with IC50 value 0.2 μM/mL, whil...

Topical Calcipotriol Plus Imiquimod Immunotherapy for Nonkeratinocyte Skin Cancers
In this study, we demonstrate that topical TSLP cytokine inducers-calcipotriol and retinoic acid-synergize with IMQ to activate CD4+ T-cell immunity against nonkeratinocyte cutaneous malignancies. Topical calcipotriol plus IMQ treatment reduced breast tumor growth compared with calcipotriol or IMQ alone (P < 0.0001). Calcipotriol plus IMQ-mediated tumor suppression was associated with significant infiltration of CD4+ effector T cells in the tumor microenvironment. Notably, topical calcipotriol plus IMQ immunotherapy enabled immune checkpoint blockade therapy to effectively control immunologically cold breast tumors, whi...

Association between ultra-processed food consumption and risk of breast cancer: a systematic review and dose-response meta-analysis of observational studies
CONCLUSION: Our results indicate that higher consumption of UPF is slightly related to a higher risk of breast cancer. Further studies in particular of large prospective cohort studies are warranted to confirm these results.PMID:37731393 | PMC:PMC10507475 | DOI:10.3389/fnut.2023.1250361

Traumatic sigmoid colon rupture due to breast cancer metastasis: a case report
Clin J Gastroenterol. 2023 Sep 21. doi: 10.1007/s12328-023-01859-x. Online ahead of print.ABSTRACTThe metastasis of breast cancer to the gastrointestinal tract is rare. Herein, we presented the case of an 85-year-old woman who had a history of invasive lobular carcinoma and experienced complete colon rupture due to relatively low-energy trauma. The patient underwent bilateral total mastectomy and axillary dissection following preoperative chemotherapy 6 years ago. She had a local recurrence 2 years after the surgery and underwent chemotherapy. Subsequently, the cancer metastasized to the thoracolumbar area and retroperiton...

Evaluation of intraoperative breast radiotherapy on local recurrence: a Brazilian cohort
CONCLUSIONS: The samples consisted of 78 patients, among which a total of 14 (17.9%) recurrences were observed. The median time of recurrence was 49 months after the IOERT was performed. Of the 78 patients analyzed, 13 (16.7%) died, 5 (6.4%) of which were due to breast cancer. The global survival rate in 5 years was 94.9% and 90.4% in 10 years. The local recurrence rate in 5 years was 89.7% and 86.4% in 10 years. Our findings revealed a higher local recurrence rate than the literature data. However, our results also showed that patients classified as low-risk had an overall survival of 5 and 10 years similar to other studi...

AZI2 mediates TBK1 activation at unresolved selective autophagy cargo receptor complexes with implications for CD8 T-cell infiltration in breast cancer
Autophagy. 2023 Sep 21. doi: 10.1080/15548627.2023.2259775. Online ahead of print.ABSTRACTMost breast cancers do not respond to immune checkpoint inhibitors and there is an urgent need to identify novel sensitization strategies. Herein, we uncovered that activation of the TBK-IFN pathway that is mediated by the TBK1 adapter protein AZI2 is a potent strategy for this purpose. Our initial observations showed that RB1CC1 depletion leads to accumulation of AZI2, in puncta along with selective macroautophagy/autophagy cargo receptors, which are both required for TBK1 activation. Specifically, disrupting the selective autophagy ...

Baseline interleukin-6 is a prognostic factor for patients with metastatic breast cancer treated with eribulin
CONCLUSION: Baseline IL-6 is an important prognostic factor in patients with MBC treated with eribulin. Our results show that high IL-6 is associated with higher levels of MDSCs which suppress anti-tumor immunity, such as CD8+ cells. It appears that eribulin is not particularly effective in patients with high IL-6 due to a poor tumor immune microenvironment.PMID:37733188 | DOI:10.1007/s10549-023-07086-9

Eribulin promotes proliferation of CD8 < sup > + < /sup > T cells and potentiates T cell-mediated anti-tumor activity against triple-negative breast cancer cells
CONCLUSIONS: Eribulin promoted CD8+ T cell proliferation, repressed effector T cell differentiation, and harnessed T cell-mediated anti-tumor effects. These mechanisms may be one of the cues that eribulin can improve the immunological status of tumor-bearing hosts.PMID:37733186 | DOI:10.1007/s10549-023-07111-x

Chromatin accessibility landscape of human triple-negative breast cancer cell lines reveals variation by patient donor ancestry
Cancer Res Commun. 2023 Sep 21. doi: 10.1158/2767-9764.CRC-23-0236. Online ahead of print.ABSTRACTAfrican American (AA) women have an excessive risk of developing triple-negative breast cancer (TNBC). We employed ATAC-sequencing to characterize differences in chromatin accessibility between 9 commonly used TNBC cell lines derived from patients of European and African ancestry. Principal component and chromosome mapping analyses of accessibility peaks with the most variance revealed separation of chromatin profiles by patient group. Motif enrichment and footprinting analyses of disparate open chromatin regions revealed diff...
