There are numerous approaches to model an influence of manufacturing parameters on the dissolution and disintegration of solid dosage forms. A modern approach for modelling and simulating complex and heterogeneous systems such as pharmaceutical tablets focuses on computationally-intensive finite-element or discreet element methods. Industrial challenges such as Process Analytical Technology (PAT) and Quality by Design are stimulating computer-based technologies to design, control and improve the quality of pharmaceutical compacts and their performance. In this study the disintegration and dissolution model based on the numerical solutions of the Noyes-Whitney equation and cellular automata supported disintegration model are proposed and evaluated. The results from in vitro release studies of the mefenamic acid formulations were compared to the calculated release patterns from the tablet structures obtained from microtomography experiments and the purely algorithmically created virtual tablets.

In the review have been classified literature data concerning modern instrumental, microscopic and molecular (metabolomics, proteomics, genetics and epigenetics) approaches for early breast cancer diagnostics. The analytical performance and perspectives of their application in clinical practice also have been evaluated.

Introduction. Menopause involves skeletal losses, which may be accelerated by breast cancer and associated therapy, as aromatase inhibitors. Case presentation. A 67-year old Caucasian female underwent 2 years ago a right mastectomy for breast cancer (invasive ductal carcinoma of mucinous type; 85-90% positive reaction of estrogen receptor). Synchronously, she presented, at computer tomography, a left adrenal hyperplasia, stationary during follow-up. Tamoxifen was continued for two years, then a switch to anastrozole was done for the last four months. On admission, the assays showed a non-secretor adrenal pattern, with negative neuroendocrine markers, including serum serotonin. Bone profile pointed mild hypercalcemia with normal parathormone levels, as well as bone turnover markers and 25-hydroxyvitamin D (negative imagery scan for bone metastases). Dual-Energy X-Ray Absorptiometry (DXA) revealed osteopenia with a mid deterioration of Trabecular Bone Score (TBS) at 1220. Further continuation of aromatase inhibitor is recommended, in association with vitamin D supplementation and monthly oral risendronate, good hydration and serial calcium assays. Conclusion. Modern approach of menopausal breast cancer with aromatase inhibitors increases the speed of age-related bone loss, while detailed imagery may find otherwise unknown artefacts as non-tumour enlargement of adrenal glands. Whether neuroendocrine markers like 5-hydroxytryptamine will find a place in this particular context, apart from traditional bone indices, is still difficult to establish.

1009 Background: Genomically-informed cancer therapy linking therapeutics targeting the molecular alterations driving the malignancy has the potential to transform the care of patients with metastatic breast cancer (MBC). Methods: DNA was isolated from 4 FFPE sections cut at 10 microns from 177 consecutive MBC that had relapsed after surgery, conventional hormonal/chemo and anti-HER2 targeted therapies received by our CLIA lab (Foundation Medicine). DNA sequencing was performed for 3,320 exons of 182 cancer-related genes to average depth of 1017X. Actionable Genomic alterations (GA) were defined as those linked to targeted anti-cancer therapies approved or being evaluated in active registered clinical trials. Results: Genomic profiles were generated from 169/177 (95%) BCs identifying 565 GA, averaging 3.34 GAs per tumor (range 0 to 10). 152 (90%) tumors harbored an actionable alteration mean 1.88 per tumor (range 0 to 6). In 124 (73%) tumors, ≥1.0 actionable GA was detected that would be missed by current “hotspot assays”. Notable GA involved PIK3CA (37%), ERBB2 (14%), FGFR1/2 (14%), PTEN (10%), MDM2 (7%), CCND1/CCNE1/CDK4 (7%), BRCA1 and BRCA2 (6% each) and ESR1 and EGFR (3% each). Of 23 ERBB2 GA, 74% were amplifications and 26% were mutation/gene fusion. The frequency of ERBB2 mutation/fusion was significantly enriched in CDH1 mutated ILC (~9% of total BC) with a frequency of 19.0% (4/21) compared to other histological types of BCs 1.4% (2/148) [p=0.002]. Significant clinical efficacy included patients with HER2 IHC/FISH negative tumors featuring HER2 and EGFR activating mutations benefitting from lapatinib/trastuzumab and erlotinib respectively. Conclusions: Comprehensive genomic profiling with a NGS assay identified actionable GAs in the majority of MBC patients including ERBB2 and EGFR mutations that initiated use of targeted therapies resulting in significant clinical benefit. These data provide a framework for the GAs expected in advanced BC and should facilitate the implementation of molecularly targeted trials supporting the efforts for a modern approach to precision medicine for the disease.

Segmentation of Breast Cancer Fine Needle Biopsy Cytological ImagesThis paper describes three cytological image segmentation methods. The analysis includes the watershed algorithm, active contouring and a cellular automata GrowCut method. One can also find here a description of image pre-processing, Hough transform based pre-segmentation and an automatic nuclei localization mechanism used in our approach. Preliminary experimental results collected on a benchmark database present the quality of the methods in the analyzed issue. The discussion of common errors and possible future problems summarizes the work and points out regions that need further research.
