Intravoxel incoherent motion diffusion-weighted MRI in patients with breast cancer: Correlation with tumor stroma characteristics

ConclusionIn breast cancer, D and f values show significant differences according to TSR, and D value is lower in collagen dominant type than in fibroblast dominant or lymphocyte dominant types.

Publication date: Available online 15 October 2019Source: Materials Science and Engineering: CAuthor(s): M. Ramazanilar, A. MojraAbstractThe biological tissue could be considered as a porous matrix filled with the interstitial fluid. The tumoral tissue has a different permeability from the healthy tissue. With regard to this knowledge, the main objective of the present study is to study the tissue permeability as a diagnostic parameter for the detection of breast cancer. To this end, the healthy and the cancerous specimens of the breast tissue are taken from 17 female cases. All cancerous tumors are in the vascular phase o...

Patients who are diagnosed with a 2 percent chance of developing breast cancer are less likely to return for the recommended 6-month scan if they have high out-of-pocket expenses, says a new  studypublished in theJournal of the American College of Radiology. Researchers from Johns Hopkins ’s Department of Radiology studied records of more than 190 women who were given the BI-RADS category 3 assessment between February 1, 2011 and June 30, 2017. They found that 57 percent went to their scheduled follow-up MRI within 10 months, 18 percent received the examination slightly after 10 mo nths, and 24 percent (or ...

Objective The aim of this study was to compare the diagnostic precision of bone scintigraphy with BONENAVI version 1 and BONENAVI version 2 in bone metastasis of primary breast cancer. Methods The subjects were 56 consecutive patients (all women, mean age 59 ± 12.7 years) who underwent bone scintigraphy with 99mTc-MDP and were diagnosed with bone metastasis of primary breast cancer from January 2012 to November 2014. Bone scintigraphy was performed with BONENAVI version 1 and BONENAVI version 2 to calculate artificial neural network (ANN), bone scan index (BSI), and hot-spot values, with ANN ≥ 0.5 considered...

CONCLUSION: Although numerous in vitro and in vivo studies have demonstrated the safety and effectiveness of the use of SPIONs for both diagnostic and therapeutic applications, there is relatively little progress towards translation to clinical applications involving breast, ovarian and cervical cancer.

Authors: Bang S, Kim Y, Chung MS, Park JS, Choi YY, Shin SJ Abstract Histiocytic sarcoma is a rare hematologic malignancy, with very few cases of primary histiocytic sarcoma of the breast described in English scientific literature. Herein, we describe a case of primary histiocytic sarcoma of the breast in a 75-year-old woman, with no clinical history of malignant tumors, who presented with a palpable solitary breast mass. Microscopically, the resected breast mass showed large pleomorphic cells, some multinucleated giant cells, and admixed inflammatory components. The pleomorphic tumor cells further showed a diffuse...

Conclusion: Anti-CV2 autoimmune encephalitis can present as Parkinsonism with bilateral leukoencephalopathy on MRI. PET scanning can be useful to reveal an occult cancer. Treatment of the cancer may improve the paraneoplastic neurological syndrome without the need of immunosuppressive therapy.

CONCLUSION: In summary, this study indicates the significant efficiency of the 68Ga labeled HER2 affibody. Preclinical and clinical studies support the possibility of monitoring HER2 levels in breast cancers using 68Ga-NOTA-MAL-Cys-MZHER2:342. ADVANCES IN KNOWLEDGE: The research investigated the feasibility of a 68Ga labeled HER2 affibody modified with a hydrophilic linker for breast cancer PET imaging. Favorable outcomes showed that the probe might be valuable for determining HER2 status of the disease. PMID: 31593482 [PubMed - as supplied by publisher]

CONCLUSION: The pre-treatment tumor SUVmax could be utilized as an independent imaging biomarker of the tumor aggressiveness and poor prognosis. Risk stratification based on this index could play a pivotal role in alteration of treatment planning, such as neoadjuvant chemotherapy (precision oncology).
