Cancer mortality rates are determined by the relationship of a population's health and lifestyle with their healthcare system. In the United States during 2013–2017, the age-adjusted mortality rate for all types of cancer was 189.5/100,000 for males, and 135.7/100,000 for females. [ 1 ]
Choriocarcinoma is a malignant, trophoblastic [1] cancer, usually of the placenta. It is characterized by early hematogenous spread to the lungs. It belongs to the malignant end of the spectrum in gestational trophoblastic disease (GTD). It is also classified as a germ cell tumor and may arise in the testis or ovary.
The most common cancer among women in the United States is breast cancer (123.7 per 100,000), followed by lung cancer (51.5 per 100,000) and colorectal cancer (33.6 per 100,000), but lung cancer surpasses breast cancer as the leading cause of cancer death among women. [13]
The survival rate following treatment with chemotherapy is approximately at least 90%. [4] If gestational choriocarcinoma has spread to the liver in an individual, survival rate may be lower. [7] Overall survival rate is also higher when management of gestational choriocarcinoma occurs in a setting with physicians familiar with the condition.
Bone metastasis, or osseous metastatic disease, is a category of cancer metastases that result from primary tumor invasions into bones. Bone-originating primary tumors such as osteosarcoma , chondrosarcoma , and Ewing sarcoma are rare; the most common bone tumor is a metastasis. [ 1 ]
Survival rate is a part of survival analysis.It is the proportion of people in a study or treatment group still alive at a given period of time after diagnosis. It is a method of describing prognosis in certain disease conditions, and can be used for the assessment of standards of therapy.
A bone tumor is an abnormal growth of tissue in bone, traditionally classified as noncancerous (benign) or cancerous (malignant). [1] [4] Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate. [1] There may be a lump, pain, or neurological signs from pressure. [1]
Cancer staging can be divided into a clinical stage and a pathologic stage. In the TNM (Tumor, Node, Metastasis) system, clinical stage and pathologic stage are denoted by a small "c" or "p" before the stage (e.g., cT3N1M0 or pT2N0). This staging system is used for most forms of cancer, except brain tumors and hematological malignancies.
