small cell lung carcinoma
Examples of small cell lung carcinoma in the following topics:
-
Lung Cancer
- The main types of lung cancer are small cell lung carcinoma (SCLC), also called oat cell cancer, and non-small cell lung carcinoma (NSCLC).
- The non-small cell lung carcinomas (NSCLC) are grouped together because their prognosis and management are similar.
- There are three main sub-types: squamous cell lung carcinoma, adenocarcinoma, and large cell lung carcinoma.
- Adenocarcinoma accounts for 40% of non-small cell lung cancers.
- Damage to chromosomes 3p, 5q, 13q, and 17p are particularly common in small-cell lung carcinoma.
-
Spinal Cord Compression
- Tumors that commonly cause cord compression are lung cancer (non-small cell type), breast cancer, prostate cancer, renal cell carcinoma, thyroid cancer, lymphoma, and multiple myeloma.
- Some tumors are highly sensitive to chemotherapy (e.g. lymphomas, small-cell lung cancer) and may be treated with chemotherapy alone.
-
Skin Cancer
- The three main types of skin cancer are basal cell carcinoma (the most common of all cancers), squamous cell carcinoma, and melanoma.
- Basal cell carcinoma usually presents as a raised, smooth, pearly bump on the sun-exposed skin of the head, neck, or shoulders.
- Sometimes small blood vessels can be seen within the tumor.
- Squamous cell carcinoma (SCC) is commonly a red, scaling, thickened patch on sun-exposed skin.
- The mortality rate of basal cell and squamous cell carcinoma is around 0.3%, causing two thousand deaths per year in the U.S.
-
Immunotherapy for Cancer
- Cell-based immunotherapy is another major entity of cancer immunotherapy.
- This involves immune cells such as the natural killer cells (NK cells), lymphokine-activated killer cells (LAK cells), cytotoxic T lymphocytes (CTLs), and dendritic cells (DC).
- GD2 is expressed on the surfaces of a wide range of tumor cells, including neuroblastomas, medulloblastomas, astrocytomas, melanomas, small-cell lung cancer, osteosarcomas, and other soft tissue sarcomas.
- The injected immune cells are highly cytotoxic to the cancer cells and so help to fight them.
- Topical immunotherapy utilizes an immune enhancement cream (imiquimod), which is an interferon producer, causing the patient's own killer T cells to destroy warts, actinic keratoses, basal cell carcinoma, squamous cell carcinoma, cutaneous T cell lymphoma, and superficial spreading melanoma.
-
Cervical Cancer
- Most cervical cancers are squamous cell carcinomas, arising in the squamous (flattened) epithelial cells that line the cervix.
- Adenocarcinoma, arising in glandular epithelial cells is the second most common type.
- Very rarely, cancer can arise in other types of cells in the cervix.
- In advanced disease, metastases may be present in the abdomen, lungs or elsewhere.
- This large squamous carcinoma (bottom of picture) has obliterated the cervix and invaded the lower uterine segment.
-
Laryngitis and Cancer of the Larynx
- Laryngeal cancer may also be called cancer of the larynx or laryngeal carcinoma.
- Most laryngeal cancers are squamous cell carcinomas, reflecting their origin from the squamous cells which form the majority of the laryngeal epithelium.
- Distant metastasis to the lung are most common.
- The larynx may be examined by indirect laryngoscopy using a small angled mirror with a long handle (akin to a dentist's mirror) and a strong light.
- For small glottic tumors further imaging may be unnecessary.
-
Overview of Cancer
- For example, patients with lung cancer often present with symptoms including breathlessness and chronic cough, but can vary widely between patients.
- Carcinoma: Cancers derived from epithelial cells.
- This group includes many of the most common cancers, particularly in the aged, and include nearly all those developing in the breast, prostate, lung, pancreas, and colon.
- Typically, changes in multiple genes are required to transform a normal cell into a cancer cell.
- A tumor present in the lung is marked via the black box.
-
Basement Membranes and Diseases
- This is achieved by cell-matrix adhesions through substrate adhesion molecules (SAMs).
- The basement membrane also acts as a mechanical barrier, preventing malignant cells from invading the deeper tissues.
- Early stages of malignancy that are thus limited to the epithelial layer by the basement membrane are called carcinoma in situ.
- Basement membrane proteins have been found to accelerate differentiation of endothelial cells.
- It is caused by a mutation in the integrin α6β4 cell-adhesion molecule on either the alpha or beta subunit.
-
Defective Viruses
- Not all viruses can reproduce in a host cell by themselves.
- Since viruses are so small, the size of their genome is limited.
- Satellites depend on co-infection of a host cell with a helper virus for productive multiplication.
- These viruses that are dependent on the presence of other virus species in the host cell are called satellites.
- Cirrhosis leading to hepatocellular carcinoma (autopsy specimen).
-
Colorectal Cancer
- Colorectal cancer, commonly known as bowel cancer, is a cancer from uncontrolled malignant cell growth in the colon, rectum, or appendix.
- Colorectal cancer, commonly known as bowel cancer, is a cancer from uncontrolled malignant cell growth in the colon, rectum, or appendix .
- If there are only a few metastases in the liver or lungs they may also be removed.
- The two most common sites of recurrence if it occurs are in the liver and lungs.
- The interior surface of the colon shows an invasive colorectal carcinoma and two adenomatous polyps.
