Summary
Inflammatory breast cancer (IBC) shows a higher MIB-1 score compared to locally advanced non-inflammatory breast cancer (LABC). This aggressive cancer subtype warrants separate consideration, with MIB-1 potentially serving as a key molecular marker.
Area of Science:
- Oncology
- Medical Research
Background:
- Inflammatory breast cancer (IBC) is the most aggressive form of primary breast carcinoma.
- IBC is associated with poor outcomes despite multimodal treatment.
Purpose of the Study:
- To compare MIB-1 scores, clinical and pathological responses, progression-free survival (PFS), and overall survival (OS) between IBC and locally advanced non-inflammatory breast cancer (LABC).
Main Methods:
- Prospective case-control study comparing 21 IBC and 21 LABC patients.
- Assessed MIB-1, ER, PR, and Her2neu.
- All patients received neoadjuvant chemotherapy (FEC100), followed by surgery, adjuvant chemotherapy, radiotherapy, and tamoxifen if applicable.
Main Results:
- IBC patients had significantly higher MIB-1 scores (81.3% vs 43.8%, P=0.028).
- Clinical response rates were 57.1% for IBC vs 81% for LABC (P=0.09).
- Two-year overall survival was significantly lower for IBC (51.20%) compared to LABC (95.24%, P=0.0038).
Conclusions:
- Inflammatory breast cancer should be recognized as a distinct entity.
- A high MIB-1 score may serve as a potential molecular marker for IBC.

01:25Inflammatory Bowel Disease III: Crohn's Disease
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

02:17The Tumor Microenvironment
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
02:30Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

02:40Cancer Stem Cells and Tumor Maintenance
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
