Understanding Cancer Cell Biology

Cancer cells grow out of control and avoid the immune system. To find good treatments, we must know how they work.
What Makes Cancer Cells Different
Cancer cells are different from normal cells. They grow too much because of genetic changes. They also change how they use energy, helping them survive in tough conditions.
These changes affect not just the cells but also the tissue around them and the immune system. Knowing these differences helps us make treatments that only harm cancer cells.
The Process of Carcinogenesis
Carcinogenesis is when normal cells turn into cancer cells. This process involves changes in genes and how genes are used. Genetic mutations can come from family history or environmental factors like UV rays or chemicals.
The process has three stages: initiation, promotion, and progression. Initiation is when the first genetic changes happen. Promotion lets these cells grow more. Progression makes the tumor grow and spread.
How Cancer Cells Evade Destruction
Cancer cells find ways to avoid the immune system. They use upregulation of checkpoint molecules like PD-L1 to stop immune cells. They also create an immunosuppressive tumor microenvironment to block immune attacks.
Understanding how cancer cells avoid the immune system is key to making better treatments. By using the immune system, we hope to find treatments that are more effective and safer.
Conventional Cancer Treatments
The main ways to treat cancer include surgery, radiation therapy, and chemotherapy. These methods have been key in fighting cancer for years. Each treatment has its own use based on the cancer type and stage.
Surgery is often the first choice for many cancers. It works best when the cancer is in one place and can be removed completely. But, it’s not always possible for cancers that have spread or are hard to reach.
Physical Removal of Tumors
Surgery aims to take out the main tumor and sometimes nearby tissue and lymph nodes. The goal is to get rid of all cancer cells. This can be tough if the cancer has grown into nearby areas. New surgical methods, like minimally invasive surgery, help patients recover faster.
Targeting Cancer Cells with Radiation
Radiation therapy kills or damages cancer cells with high-energy particles or waves. It breaks the DNA of cancer cells, stopping them from growing. Radiation can be given from outside or inside the body, depending on the cancer’s location and type.
Most people get external beam radiation therapy from a machine outside their body. Internal radiation, or brachytherapy, places radioactive material close to the tumor inside the body.
Systemic Treatment with Chemotherapy
Chemotherapy uses drugs to kill cancer cells all over the body. It’s great for cancers that have spread or are likely to spread. Chemotherapy can be taken by mouth or through an IV, depending on the drug.
Chemotherapy is effective but can cause serious side effects. This is because it affects fast-growing cells, like hair follicles and the digestive tract lining. Managing these side effects is a big part of chemotherapy care.
In summary, surgery, radiation therapy, and chemotherapy are the main cancer treatments. Knowing how each works and its limits is key to making good treatment plans.
Targeted Therapy: Precision Medicine
Targeted therapy has changed cancer treatment, making it more precise. It focuses on cancer cells, unlike old treatments that harm both cancer and healthy cells. This new method targets specific molecules that help cancer grow.
Molecular Targeting Mechanisms
Targeted therapy finds and attacks specific ways cancer cells grow and live. It uses the unique genetic and molecular traits of a patient’s cancer to pick the best treatment.
Key mechanisms include:
- Blocking signals that promote cancer cell growth
- Inhibiting angiogenesis, the formation of new blood vessels that supply the tumor
- Triggering apoptosis, or programmed cell death, in cancer cells
- Delivering cytotoxic agents directly to cancer cells
Tyrosine Kinase Inhibitors
Tyrosine kinase inhibitors (TKIs) block enzymes called tyrosine kinases. These enzymes activate proteins in cancer cells. TKIs treat cancers like chronic myeloid leukemia (CML) and non-small cell lung cancer (NSCLC).
Examples of TKIs include:
- Imatinib (Gleevec)
- Erlotinib (Tarceva)
- Afatinib (Gilotrif)
Monoclonal Antibodies
Monoclonal antibodies target specific proteins on cancer cells. They mark these cells for destruction by the immune system or stop their growth.
Examples include:
- Rituximab (Rituxan), used in treating non-Hodgkin lymphoma
- Trastuzumab (Herceptin), used in HER2-positive breast cancer
- Bevacizumab (Avastin), which targets VEGF to inhibit angiogenesis
Research is also looking into SIRPα inhibitors as a new targeted therapy. They aim to boost anti-tumor immunity.
Immunotherapy: Harnessing the Body’s Defenses
Immunotherapy uses the body’s immune system to fight cancer. It makes the body’s defenses stronger to attack cancer cells better.
Checkpoint Inhibitors
Checkpoint inhibitors help the immune system fight cancer. They block proteins that stop immune cells from attacking cancer. Drugs like pembrolizumab and nivolumab are helping treat cancers like melanoma and lung cancer.
CAR T-Cell Therapy
CAR T-cell therapy takes T cells from a patient, changes them to find cancer, and puts them back. This personalized treatment is showing great results for some blood cancers.
Cancer Vaccines and Oncolytic Viruses
Cancer vaccines help the immune system fight cancer cells. They are not like regular vaccines but are used to treat cancer. Oncolytic viruses also target and kill cancer cells, boosting the immune response.
Immunotherapy offers new ways to fight cancer with the body’s immune system. It gives hope to patients and.
Hormone Therapy for Hormone-Sensitive Cancers
Hormone therapy is key in treating hormone-sensitive cancers like some breast and prostate cancers. It works by lowering hormone levels or blocking their effects on cancer cells.
Breast Cancer Hormone Treatments
In breast cancer, hormone therapy is used for cancers that grow because of hormones like estrogen or progesterone. Treatments include:
- Selective Estrogen Receptor Modulators (SERMs): Drugs like tamoxifen that block estrogen receptors on cancer cells.
- Aromatase Inhibitors (AIs): Medications that lower estrogen levels in the body, used mainly in postmenopausal women.
A study in the Journal of Oncology shows hormone therapy has greatly improved survival rates for hormone receptor-positive breast cancer patients.
Prostate Cancer Hormone Approaches
For prostate cancer, hormone therapy aims to lower male hormones like testosterone. These hormones can help prostate cancer cells grow. Approaches include:
- Orchiectomy: Surgical removal of the testicles to reduce testosterone production.
- Luteinizing Hormone-Releasing Hormone (LHRH) Agonists and Antagonists: Medications that decrease testosterone production.
| Treatment | Mechanism | Common Use |
| Orchiectomy | Surgical removal of testicles | Advanced Prostate Cancer |
| LHRH Agonists | Reduce testosterone production | Localized and Advanced Prostate Cancer |
Endocrine Therapy Side Effects Management
Hormone therapy can cause side effects like hot flashes, osteoporosis, and changes in libido. It’s important to manage these side effects to keep patients’ quality of life good.
Managing side effects can include lifestyle changes and medications. This helps patients live better with hormone therapy.
Understanding hormone therapy’s role in treating hormone-sensitive cancers and managing side effects is key. Healthcare providers can then offer personalized care that improves patient outcomes.
Stem Cell Transplantation and Cellular Therapies
Stem cell transplantation and cellular therapies are changing how we treat cancer. This section will look at stem cell transplantation. We’ll cover the types of transplants, the conditions they treat, and new ways to use cells.
Autologous vs. Allogeneic Transplants
There are two main types of stem cell transplants: autologous and allogeneic. Autologous transplants use the patient’s own stem cells. These cells are collected, stored, and then given back after treatments. This method lowers the risk of graft-versus-host disease (GVHD).
Allogeneic transplants use stem cells from a donor. This method can fight cancer but also risks GVHD. The choice between these transplants depends on the cancer type, the patient’s health, and if a donor is available.
Conditions Treated with Stem Cell Therapy
Stem cell transplantation helps treat many cancers, including:
- Multiple myeloma
- Leukemia
- Lymphoma
- Other hematologic malignancies
Stem cell therapy has shown great results in these conditions. It offers hope to those who haven’t seen success with other treatments.
