Specialty. Medical genetics. Distal 18q- is a genetic condition caused by a deletion of genetic material within one of the two copies of chromosome 18. [1] The deletion involves the distal section of 18q and typically extends to the tip of the long arm of chromosome 18. [2]
Medical genetics. Proximal 18q- is a rare genetic condition caused by a deletion of genetic material within one of the two copies of chromosome 18. This deletion involves the proximal (near the centromere) section of the long arm of chromosome 18 somewhere between 18q11.2 (18.9 Mb) to 18q21.1 (43.8 Mb). [1] Exact breakpoints vary.
Limited-stage small cell lung carcinoma. persistent cough, chest pains, rust-coloured sputum, shortness of breath, fatigue, weight loss, wheezing, hoarseness, pneumonia, bronchitis. median overall survival time of approximately 12–16 months, with five-year survival rate of approximately 26% and the long-term survival rate of approximately 4 - 5%.
Small-cell carcinoma is a type of highly malignant cancer that most commonly arises within the lung, [1] although it can occasionally arise in other body sites, such as the cervix, [2] prostate, [3] and gastrointestinal tract. Compared to non-small cell carcinoma, small cell carcinoma is more aggressive, with a shorter doubling time, higher ...
Lung cancer staging is the assessment of the extent to which a lung cancer has spread from its original source. As with most cancers, staging is an important determinant of treatment and prognosis. In general, more advanced stages of cancer are less amenable to treatment and have a worse prognosis. The initial evaluation of non-small cell lung ...
Chromosome 18 pair in human male karyogram. Chromosome 18 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 18 spans about 80 million base pairs (the building material of DNA) and represents about 2.5 percent of the total DNA in cells .
17q12 microdeletion syndrome. 17q12 microdeletion syndrome, also known as 17q12 deletion syndrome, is a rare chromosomal anomaly caused by the deletion of a small amount of material from a region in the long arm of chromosome 17. It is typified by deletion of the HNF1B gene, resulting in kidney abnormalities and renal cysts and diabetes syndrome.
Researchers with the American Cancer Society (ACS) assessed rates of 34 different cancers among those born between 1920 and 1990, based on how many were diagnosed with or died of the disease from ...
