Different stage of cancer

See http://seer.cancer.gov/cgi-bin/glossary/glossary.pl

  • In situ cancer is early cancer that is present only in the layer of cells in which it began.
  • Localized cancer is cancer that is limited to the organ in which it began, without evidence of spread.
  • Regional cancer is cancer that has spread beyond the original (primary) site to nearby lymph nodes or organs and tissues.
  • Distant cancer is cancer that has spread from the primary site to distant organs or distant lymph nodes.
  • Unstaged cancer is cancer for which there is not enough information to indicate a stage.

治療方法

化療(chemotherapy)和放療(radiation therapy)

化疗和放疗为什么不能治愈癌症?

Neoadjuvant therapy 新輔助療法

(cancer.gov) Treatment given as a first step to shrink a tumor before the main treatment, which is usually surgery, is given. Examples of neoadjuvant therapy include chemotherapy, radiation therapy, and hormone therapy. It is a type of induction therapy.

Adjuvant therapy 輔助治療

(cancer.gov) Additional cancer treatment given after the primary treatment to lower the risk that the cancer will come back. Adjuvant therapy may include chemotherapy, radiation therapy, hormone therapy, targeted therapy (Balversa - FDA approves first targeted therapy for metastatic bladder cancer), or biological therapy.

What Are the Different Types of Clinical Research? fda.gov

What Happens in a Clinical Trial? Phase III of a clinical trial usually involves up to 3,000 participants who have the condition that the new medication is meant to treat.

What Are the Phases of Clinical Trials? cancer.org

  • Phase I clinical trials: Is the treatment safe?
  • Phase II clinical trials: Does the treatment work?
    • Usually, a group of 25 to 100 patients with the same type of cancer get the new treatment in a phase II study.
    • No placebo (sham or inactive treatments) is used.
  • Most phase III clinical trials have a large number of patients, at least several hundred.
    • Placebos may be used in some phase III studies, but they’re never used alone if there’s a treatment available that works.
    • Phase III clinical trials: Is it better than what’s already available?

Breast cancer

  • https://en.wikipedia.org/wiki/Breast_cancer, https://en.wikipedia.org/wiki/Breast_cancer_classification#Receptor_status
    • estrogen receptors (ER+) and progesterone receptors (PR+)
    • Breast cancer cells have receptors on their surface and in their cytoplasm and nucleus. Chemical messengers such as hormones bind to receptors, and this causes changes in the cell.
    • Breast cancer cells may or may not have three important receptors: estrogen receptor (ER)雌激素受體, progesterone receptor (PR)孕酮受體, and HER2表皮生長因子受體-2.
    • ER+ cancer cells (that is, cancer cells that have estrogen receptors) depend on estrogen for their growth, so they can be treated with drugs to block estrogen effects (e.g. tamoxifen), and generally have a better prognosis.
    • 超過10%乳癌患者的TP53、PIK3CA和GATA3基因有突變。
  • Generally, after surgery, such patients receive endocrine therapy, such as tamoxifen, which is designed to block the cancer-spurring effects of hormones.
  • Take a closer look at biomarkers to better understand your patients’ disease
    • HR and HER2 are prognostic biomarkers
    • HR-positive disease is the most common subtype and results in the majority of breast cancer deaths
    • BRCA is another biomarker that can provide you with additional valuable information
