Flashcards in CANCER STAGING AND TUMOR TYPES Deck (38)
What is staging?
Process of finding out how much cancer is in a person’s body and where it is located
Staging helps with treatment plans and predict a person’s prognosis
The stage is based on four main factors?
1. Location of the primary tumor
2. Tumor size and extent of tumors
3. Lymph node involvement
4. Presence or absence of distant metastasis
1. Why is staging needed? 3
2. What is looked at when staging cancer? 5
3. How are cancers staged? 5
-Amount of cancer
-Where in the body
For example, the treatment for an early-stage cancer may be surgery or radiation, while a more advanced-stage cancer may need to be treated with chemotherapy.
- Extent of growth
- Lymph nodes
- Spread to distant areas
What are the types of staging?
1. Clinical staging
-Estimate of the extent of cancer based on results
2. Pathologic staging
3. Post-Therapy/Post-Neoadjuvant -Therapy Staging
Cancer staging: The TNM system?
T stands for the primary tumor
N stands for nodes
M stands for metastasis
T category gives info about primary tumor: Such as?
2. How deep it has grown into the organ it started
3. If it has grown into nearby tissues
CANCER STAGING: Describe what the followng mean:
Numbers after the T (T1-T4)?
TX: Means tumor can’t be measured
T0: Means there is no evidence of a primary tumor
Tis: Means that cancer cells are only growing into most superficial layers, without growing into deeper tissues
-Describe the tumor size
-Amount of spread into nearby tissues
-Higher the T number, the larger the tumor and spread to nearby tissue
1. N category describes what?
4. Numbers after the N? (1-3)
1. N category describes whether the cancer has spread into the lymph nodes
2. NX: Means the nearby lymph nodes can’t be evaluated
3. N0: Means nearby lymph nodes do not contain cancer
4. Numbers after the N (N1-N3)
1. M category describes what?
1. M category tell whether cancer has spread (metastasized) to distant body parts
2. M0: Means that no cancer spread was found
3. M1: Means cancer has spread to distant organs or tissues
Once TNM has been determined, cancer is staged in what?
Describe each stage:
3. Stage 0?
Roman numerals I-IV
1. I is least advanced
2. IV is most advanced
-Some will be subdivided with A & B (IIA, IIIB)
3. Stage 0 is carcinoma in situ for most cancers
Describe severity of Stage I, Stage II, and Stage III?
Higher numbers indicate more extensive disease: Larger tumor size and/or spread of the cancer beyond the organ in which it first developed to nearby lymph nodes and/or tissues or organs adjacent to the location of the primary tumor
Describe severity of stage IV?
Other staging terms? 5
The cancer has spread to distant tissues or organs
Other staging terms:
1. In situ
1. The stage of the cancer is determined only when what?
2. How does the stage change over time?
3. Survival statistics and info on treatment by stage refers to the stage when the cancer was what?
4. “Restaging” is what?
5. A ____ is written before the new stage

2. The stage does not change over time
3. first diagnosed
4. Term used to describe doing test to find the extent of the cancer after treatment
5. Multiple Myeloma
