2. Esophageal cancer - Wikipedia

   en.wikipedia.org/wiki/Esophageal_cancer

   Until the 1970s, squamous-cell carcinoma accounted for the vast majority of esophageal cancers in the United States. In recent decades, incidence of adenocarcinoma of the esophagus (which is associated with Barrett's esophagus) steadily rose in the United States to the point that it has now surpassed squamous-cell carcinoma.

3. Gastrointestinal cancer - Wikipedia

   Esophageal squamous-cell carcinomas may occur as second primary tumors associated with head and neck cancer, due to field cancerization (i.e. a regional reaction to long-term carcinogenic exposure). [20] [21] A field defect associated with progression towards squamous cell carcinoma can be identified with epigenetic markers. [22]

4. Squamous-cell carcinoma - Wikipedia

   en.wikipedia.org/wiki/Squamous-cell_carcinoma

   Squamous-cell carcinoma (SCC), also known as epidermoid carcinoma, comprises a number of different types of cancer that begin in squamous cells. [1] These cells form on the surface of the skin, on the lining of hollow organs in the body, and on the lining of the respiratory and digestive tracts .

5. Cancer survival rates - Wikipedia

   en.wikipedia.org/wiki/Cancer_survival_rates

   Small cell lung cancer has a five-year survival rate of 4% according to Cancer Centers of America's Website. [5] The American Cancer Society reports 5-year relative survival rates of over 70% for women with stage 0-III breast cancer with a 5-year relative survival rate close to 100% for women with stage 0 or stage I breast cancer.

6. Progression-free survival - Wikipedia

   en.wikipedia.org/wiki/Progression-free_survival

   Progression-free survival (PFS) is "the length of time during and after the treatment of a disease, such as cancer, that a patient lives with the disease but it does not get worse". [1] In oncology , PFS usually refers to situations in which a tumor is present, as demonstrated by laboratory testing, radiologic testing, or clinically.

7. Five-year survival rate - Wikipedia

   en.wikipedia.org/wiki/Five-year_survival_rate

   Five-year survival rates can be used to compare the effectiveness of treatments. Use of five-year survival statistics is more useful in aggressive diseases that have a shorter life expectancy following diagnosis, such as lung cancer , and less useful in cases with a long life expectancy, such as prostate cancer .
