Prostate cancer staging is the process by which physicians categorize the risk of cancer having spread beyond the prostate, or equivalently, the probability of being cured with local therapies such as surgery or radiation. Once patients are placed in prognostic categories, this information can contribute to the selection of an optimal approach ...
Stage 0 can also mean no remaining cancer after preoperative treatment in some cancers (e.g. colorectal cancer). Stage I: cancers are localized to one part of the body. Stage I cancer can be surgically removed if small enough. Stage II: cancers are locally advanced. Stage II cancer can be treated by chemotherapy, radiation, or surgery.
G (1–4): the grade of the cancer cells (i.e. they are "low grade" if they appear similar to normal cells, and "high grade" if they appear poorly differentiated) S (0–3): elevation of serum tumor markers; R (0–2): the completeness of the operation (resection-boundaries free of cancer cells or not) Pn (0–1): invasion into adjunct nerves
Metabolites are potentially useful for predicting treatment response since they are the endpoint of many molecular pathways. [10] For example, Sreekumar et al reported that the level of sarcosine, which is a derivative of glycine, in the urine of men is correlated with metastasis of prostate cancer .
Patients in response categories 4-9 should be considered as failing to respond to treatment (disease progression). Thus, an incorrect treatment schedule or drug administration does not result in exclusion from the analysis of the response rate. Precise definitions for categories 4-9 will be protocol specific.
Cancer treatments are a wide range of treatments available for the many different types of cancer, with each cancer type needing its own specific treatment. [1] Treatments can include surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy including small-molecule drugs or monoclonal antibodies, [2] and PARP inhibitors such as olaparib.

Ohio Sen. Sherrod Brown (D) said he’s “not dismissing” another Senate run after he was defeated in his run for reelection this year. Brown spoke with CNN’s Manu Raju on Sunday, where he ...
It is a metric frequently used by the UK National Institute for Health and Clinical Excellence [6] and the U.S. Food and Drug Administration to evaluate the effectiveness of a cancer treatment. Studies find that new cancer drugs approved by the U.S. Food and Drug Administration improve progression-free survival by a median of 2 to 3 months ...
