What is the most common route of metastasis for breast cancer?
Metastasis or tumor cell dissemination occurs via the hematogenous and lymphatic systems. For many carcinomas, the dissemination of tumor cells via lymphatic drainage of the tumor is the most common metastatic route.
What are breast cancer cell lines?
Introduction. Human breast cancer cell lines (bcc) selected for resistance to antineoplastic agents are a valuable research tool for studying the mechanisms associated with the development of drug resistance, the major cause for chemotherapy failure in breast cancer patients.
Where is the first place breast cancer spreads to?
The lymph nodes under your arm, inside your breast, and near your collarbone are among the first places breast cancer spreads. It’s “metastatic” if it spreads beyond these small glands to other parts of your body.
What are the three most common sites of breast metastases?
Symptoms and diagnosis of metastatic breast cancer The most common parts of the body where breast cancer tends to spread (metastasize) are the bones, lungs, brain, and liver. But metastatic breast cancer can affect other parts of the body, as well.
How long does it take breast cancer to metastasize?
Each division takes about 1 to 2 months, so a detectable tumor has likely been growing in the body for 2 to 5 years. Generally speaking, the more cells divide, the bigger the tumor grows.
How do you know if breast cancer has metastasized?
Symptoms of metastatic breast cancer Bone pain or bone fractures due to tumor cells spreading to the bones or spinal cord. Headaches or dizziness when cancer has spread to the brain. Shortness of breath or chest pain, caused by lung cancer. Jaundice or stomach swelling.
How many breast cancer cell lines are there?
List of cell lines
| Cell line | Primary tumor | Origin of cells |
|---|---|---|
| Evsa-T | Invasive ductal carcinoma, mucin-producing, signet-ring type | Metastasis (ascites) |
| Hs578T | Invasive ductal carcinoma | Primary |
| MCF-7 | Invasive ductal carcinoma | Metastasis (pleural effusion) |
| MDA-MB-231 | Adenocarcinoma | Metastasis (pleural effusion) |
What are cell lines?
Cell lines are cultures of animal cells that can be propagated repeatedly and sometimes indefinitely. They arise from primary cell cultures. Primary cultures are initiated directly from the cells, tissues, or organs of animals and are typically used in experiments within a few days.
How long does it take for breast cancer to metastasize?
What were your first symptoms of metastatic breast?
Symptoms of metastatic breast cancer
- Bone pain or bone fractures due to tumor cells spreading to the bones or spinal cord.
- Headaches or dizziness when cancer has spread to the brain.
- Shortness of breath or chest pain, caused by lung cancer.
- Jaundice or stomach swelling.
Is invasive ductal carcinoma metastatic?
Without prompt treatment, invasive ductal carcinoma can spread to lymph nodes or blood vessels and metastasize (spread) throughout the body. Identifying characteristics of the tumor, such as whether or not the cells are sensitive to certain hormones, can help your doctor choose the best treatment.
How do you know if breast cancer has spread to brain?
If breast cancer metastasizes to the brain, it can cause a variety of symptoms to develop, including:
- Headaches.
- Memory loss.
- Changes in mood, personality or behavior.
- Impaired judgment.
- Dizziness.
- Balance problems.
- Weakness or paralysis in one side of the body (hemiparesis)
- Numbness or tingling within the extremities.
Are breast cancer cell lines similar to metastatic breast cancer samples?
Using breast cancer as a case study, we comprehensively compare multiple types of molecular features between breast cancer cell lines and metastatic breast cancer samples (Fig. 1a–e ). Based on our analyses, we identify cell lines that closely resemble the transcriptome of different subtypes of metastatic breast cancer samples.
Do metastatic breast cancer cells have a transcriptome signature?
The top 20 cell lines were all breast cancer cell lines, suggesting metastatic breast cancer cells retain the transcriptomic signature from the tissue they originated in and cell lines have the potential to resemble the transcriptome of them (Fig. 3a ).
Do cell lines recapitulate metastatic cancer in patients?
… Cell lines are widely-used models to study metastatic cancer although the extent to which they recapitulate the disease in patients remains unknown. The recent accumulation of genomic data provides an unprecedented opportunity to evaluate the utility of them for metastatic cancer research.
Which breast cancer cell lines are most commonly used in research?
We next searched PubMed to examine the popularity of the 57 breast cancer cell lines (see Methods and Supplementary Data 2 ). MCF7 is most commonly used in metastatic breast cancer research (43.6% of total PubMed citations).
