neoplasm
|
an abnormal mass of tissue; can be benign or malignant
|
|
benign
|
unregulated growth WITHOUT tissue invasion
abnormal cell but no invasion into tissues |
|
malignant
|
unregulated growth WITH tissue invasion +/- metastases
|
|
metastasis
|
distant spread of neoplasm
ex. lung cancer metastasized to brain |
|

|
prostate
2: lung 3: colon |
|
What is the most common cancer in women?
|
breast
2: lung 3: colon |
|
cancer
|
uncontrolled growth of abnormal cells in the body
|
|
What type of cancer is the #1 killer of men?
|
lung
2: prostate 3: colon |
|
What type of cancer is the #1 killer of women?
|
lung
2: breast 3: colon |
|
What are the main causes of cancer?
|
#1: idiopathic (unknown)
carcinogens; ionizing radiation; UV light; bacterial/viral; genetic (breast cancer: BRCA1/2); meds |
|
What types of meds can cause cancer?
|
hormonal agents (estrogens)
chemo agents (2nd cancers) immunomodulators (azathioprine) |
|
carcinoma
|
cancer of epithelial tissue (most of organs such as breast, colon, lung); organs & tissues epithelium that line: lung, colon, liver, prostate, kidney, breast, ovulation, skin
|
|
melanoma
|
cancer of the melanocytes (pigment cells in the skin)
|
|
sarcoma
|
cancer of mesenchymal tissue (bone, muscle, & fat)
more rare |
|
leukemia
|
cancer of hematopoietic stem cells (cells in bone marrow & blood)
liquid tumor |
|
lymphoma
|
cancer of lymphoid cells (B cells, T cells, & lymph cells)
liquid cancer |
|
What are the signs & symptoms of cancer?
|
asymptomatic
non-specific unexplained weight loss - common fever - common fatigue - common pain skin changes sometimes cancer specific |
|
fine needle aspiration (FNA)
|
type of biopsy to diagnose cancer by taking a needle size piece of tumor
|
|
excisional biopsy
|
take whole thing out
ex. lymphoma - remove whole lymph node |
|
incisional biopsy
|
taking a piece of the tissue
|
|
What are the different ways to diagnose cancer?
|
- biopsy - tissue sample needed for definitive diagnosis
- lab values: peripheral blood - CBC, specific markers - imaging studies or scans: size of tumor, penetration or effect on different organ systems; distant metastasis |
|
What are the factors that determine the particular stage of cancer?
|
- dx specific
- oncology/solid organ: TNM staging - dx progression: I-IV (w/ I has not progressed as much) - prognosis |
|
TNM Staging
|
most common school of staging
T: tumor size or location N: what lymph nodes or how many the cancer is in M: metastasis |
|
cure
|
cancer goes away forever (magic #: 5)
|
|
remission
|
cancer goes away but not @ 5 yr mark
|
|
relapse
|
have cancer before, you went into remission, cancer came back
|
|
Overall Survival (OS)
|
time from start of tx until death (endpoint: death)
|
|
Progression Free Survival (PFS)
|
time from start of tx until dx progresses or grows (shorter than overall survival)
used in cancer where goal is to prevent cancer from growing; not going to get rid of it; look @ point where dx grows |
|
What are the 2 types of cancer treatment?
|
local & systemic
|
|
local cancer treatment
|
surgery; radiation
|
|
systemic cancer treatment
|
chemotherapy; other
|
|
What is the goal of surgery in cancer treatment?
|
to have negative margins (where all cancer is removed by surgery & around the cancer is all normal tissue)
positive margin: some of cancerous tissue is in outside of margins of area that was excised |
|
What are the adverse effects of surgery?
|
bronchopneumonia
congestive heart failure acute myocardial infarction pulmonary embolism respiratory failure |
|
What is the purpose of surgery?
|
curative
treatment, along w/ other modes debulking palliative sx reconstruction urgent |
|
radiation therapy (XRT)
|
medical use of ionizing radiation to control cancer
types: external beam & brachytherapy or internal (placement of radioactive material in tumor) |
|
What is the purpose of radiation?
|
curative
palliative concurrent chemoradiation (Ex. Cisplatin) |
|
What are the adverse effects of radiation?
|
acute (1-2 wks): mucositis; N/D; fatigue; proctitis
subacute (2-3 wks): pneumonitis; liver dx chronic (> 6 mo): fibrosis; fistula formation; organ damage; bowel obstruction; secondary cancer |
|
Chemotherapy Regimen
|
medications used together to treat cancer
Ex. AC or doxorubicin (Adriamycin) & cyclophosphamide for breast cancer |
|
Chemotherapy Cycle
|
number of days for treatment plus days to recover b/t treatments
Ex. AC has 14 day cycle, given for 4 cycles |
|
What is the purpose of chemotherapy?
|
systemic treatment
curative adjuvant (given after surgery or radiation) neoadjuvant (given before surgery or radiation) palliative direct instillation into tumor |
|
doubling time
|
time that cancer takes to double in number of cells or certain level
(faster doubling time = more aggressive cancer = chemo more effective) |
|
What are the adverse effects of chemotherapy?
|
myelosuppression
N/V alopecia mucositis infertility (usually not irreversible) |
|
targeted therapy
|
medications that specifically target cancer cells on a molecular level (gene expression; growth regulation; angiogenesis, Ex. bevacizumab (Avastatin))
|
|
What are the adverse effects of targeted therapy?
|
infusion reactions
acneiform rash (more rash = better response) diarrhea |
|
hormonal therapy
|
seen in cancers that grow due to release of hormones
Ex. tamoxifen, selective anti-estrogen for breast cancer |
|
biological response modifiers
|
used for cancers sensitive to the immune system
Ex. interleukin-2 for melanoma |
