Small-cell carcinoma also known as small-cell lung canceror oat-cell carcinoma is a type of highly malignant cancer that most commonly arises within the lung although it can occasionally arise in other body sites, such as the cervix prostate and gastrointestinal tract. Compared to non-small cell carcinomasmall cell carcinoma has a shorter doubling time, higher growth fraction, and earlier development of metastases. Small-cell carcinoma of the csrcinoma usually presents in the central airways and infiltrates the submucosa leading to narrowing of bronchial airways.
Common symptoms include cough, dyspnea, weight loss, and debility. Due to its high grade neuroendocrine nature, small-cell carcinomas can produce ectopic hormonesbroncogdnico adrenocorticotropic hormone ACTH and anti-diuretic hormone ADH. Lambert-Eaton myasthenic syndrome LEMS is a well-known paraneoplastic condition linked to broncogemico carcinoma. When associated with the lung, it is sometimes called “oat cell carcinoma” due to the flat cell shape and scanty cytoplasm.
Small-cell carcinoma is most often more rapidly and widely metastatic than non-small cell lung carcinoma  and hence staged differently. There is usually early involvement of the hilar and mediastinal lymph nodes.
Small-cell lung carcinoma can occur in combination with a carcinomaa variety of other histological variants of lung cancer including extremely complex malignant tissue admixtures.
Although combined small-cell lung carcinoma is currently staged and treated similarly to “pure” small-cell carcinoma of the lung, recent research suggests surgery might improve outcomes in very early stages of this tumor type. Symptoms and signs are as for other lung cancers. In addition, because of their neuroendocrine cell origin, small-cell carcinomas will often secrete substances that result in paraneoplastic syndromes such as Lambert-Eaton myasthenic syndrome.
Very rarely, the primary site for small-cell carcinoma is outside of the lungs and pleural space, it is referred to as extrapulmonary small-cell carcinoma EPSCC. Outside of the respiratory tract, small-cell carcinoma can appear in the cervix, prostate, liver, pancreas, gastrointestinal tract, or bladder. Histologically similar to small-cell lung cancer, therapies for small-cell lung cancer are usually used to treat EPSCC.
In Japan, the first line treatment is shifting to irinotecan and cisplatin. This is an extremely rare type of small cell, and there has been little information in the scientific community. It appears to occur in only one or more lymph nodes, and nowhere else in the body. Treatment is similar to small cell lung cancer, but survival rates are much higher than other small-cell carcinomas.
It can metastasize to the brain. Small-cell carcinoma is an undifferentiated neoplasm composed of primitive-appearing cells. As the name implies, the cells in small-cell carcinomas are smaller than normal cells, and barely have room for any cytoplasm.
Some researchers identify this as a failure in the mechanism that controls the size of the cells. Small-cell lung carcinoma has long been divided into two clinicopathological stages, including limited stage LS and extensive stage ES. The stage is generally determined by the presence broncofenico absence of metastases, whether or not the tumor appears limited to the thorax, and whether or not the entire tumor burden within the chest can feasibly be encompassed within a single radiotherapy portal.
If the cancer has spread beyond that, it is said to be ES. However, relapse rate remains high, and median survival is only 18 to 24 months. In ES-SCLC, platinum-based combination chemotherapy is the standard of care,  with radiotherapy added only to palliate symptoms carcinomw as dyspneapain from liver or bone metastases, or for treatment of brain metastaseswhich, in small-cell lung carcinomatypically have a rapid, if czrcinoma, response to whole brain radiotherapy.
Combination chemotherapy consists of a wide variety of agents, including cisplatincyclophosphamidevincristine and carboplatin. Responses in ES-SCLC are often of short duration, and the evidence surrounding the risk of treatment compared to the potential benefit of chemotherapy for people who have extensive SCLC is not clear. If complete response to chemotherapy occurs in a subject with SCLC, then prophylactic cranial irradiation PCI is often used in an attempt to prevent the emergence of brain metastases.
Although this treatment is often effective, it can cause hair loss and fatigue. Prospective randomized trials with almost two years follow-up have not shown neurocognitive ill-effects. Meta-analyses of randomized trials confirm that PCI provides significant survival benefits. All in all, small-cell carcinoma is very responsive to chemotherapy and radiotherapyand in particular, regimens based on platinum-containing agents.
However, most people with the disease relapse, and median survival remains low.
