PERAWATAN KANKER
DEFINISI
• penyakit yang menyerang proses dasar kehidupan sel,
mengubah genom sel (komplemen genetik total sel)
dan menyebabkan penyebaran liar dan pertumbuhan
sel-sel.
• sebuah penyakit yang ditandai dengan pembagian sel
yang tidak teratur dan kemampuan sel-sel ini untuk
menyerang jaringan biologis lainnya, baik dengan
pertumbuhan langsung di jaringan yang bersebelahan
(invasi) atau dengan migrasi sel ke tempat yang jauh
(metastasis). Pertumbuhan yang tidak teratur ini
menyebabkan kerusakan DNA, menyebabkan mutasi di
gen vital yang mengontrol pembagian sel, dan fungsi
lainnya
“Akar Kata”
•
•
•
•
•
•
Neo- raru
Plasia-pertumbuhan
Plasm- substance
Trophy- ukuran
+Oma- tumor/benjolan
Statis- lokasi/regio
“Akar Kata”
•
•
•
•
•
A- tidak/tidak ada
Ana- kekurangan/ketiadaan
Hyper- berlebihan/terlalu banyak
Meta- perubahan/penyebaran
Dys- kekurangan, kesakitan/nyeri
Karakteristik Neoplasia
•
•
•
•
Pertumbuhan Sel Abnormal tidak Terkontrol
1. Benign  tumor jinak
2. Malignant  tumor ganas
3. Borderline  tumor jinak mengarah
keganasan
Characteristics of Neoplasia
•
•
•
•
•
•
BENIGN
Well-differentiated
Slow growth
Encapsulated
Non-invasive
Does NOT metastasize
Characteristics of Neoplasia
•
•
•
•
•
•
MALIGNANT
Undifferentiated
Erratic and Uncontrolled Growth
Expansive and Invasive
Secretes abnormal proteins
METASTASIZES
Nomenclature of Neoplasia
Tumor is named according to:
1. Parenchyma, Organ or Cell
• Hepatoma- liver
• Osteoma- bone
• Myoma- muscle
Nomenclature of Neoplasia
Tumor is named according to:
2. Pattern and Structure, either GROSS or
MICROSCOPIC
• Fluid-filled CYST
• Glandular ADENO
• Finger-like PAPILLO
• Stalk POLYP
Nomenclature of Neoplasia
Tumor is named according to:
3. Embryonic origin
• Ectoderm ( usually gives rise to epithelium)
• Endoderm (usually gives rise to glands)
• Mesoderm (usually gives rise to Connective
tissues)
BENIGN TUMORS
•
•
•
•
•
•
Suffix- “OMA” is used
Adipose tissue- LipOMA
Bone- osteOMA
Muscle- myOMA
Blood vessels- angiOMA
Fibrous tissue- fibrOMA
MALIGNANT TUMOR
• Named according to embryonic cell origin
1. Ectodermal, Endodermal, Glandular, Epithelial
• Use the suffix- “CARCINOMA”
• Pancreatic AdenoCarcinoma
• Squamos cell Carcinoma
MALIGNANT TUMOR
• Named according to embryonic cell origin
2. Mesodermal, connective tissue origin
• Use the suffix “SARCOMA
• FibroSarcoma
• Myosarcoma
• AngioSarcoma
“PASAWAY”
1. “OMA” but Malignant
– HepatOMA, lymphOMA, gliOMA, melanOMA
2. THREE germ layers
– “TERATOMA”
3. Non-neoplastic but “OMA”
– Choristoma
– Hamatoma
Etiology of cancer
1. PHYSICAL AGENTS
• Radiation
• Exposure to irritants
• Exposure to sunlight
• Altitude, humidity
2. CHEMICAL AGENTS
• Smoking
• Dietary ingredients
• Drugs
3. Genetics and Family History
• Colon Cancer
• Premenopausal breast cancer
4. Dietary Habits
• Low-Fiber
• High-fat
• Processed foods
• Alcohol
5. Viruses and Bacteria
• DNA viruses- HepaB, Herpes, EBV, CMV,
Papilloma Virus
• RNA Viruses- HIV, HTCLV
• Bacterium- H. pylori
6. Hormonal agents
• Pada beberapa penelitian diketahui bahwa
pemberian hormon tertentu secara berlebihan
dapat menyebabkan peningkatan terjadinya
beberapa jenis kanker seperti payudara,
rahim, indung telur dan prostat (kelenjar
kelamin pria)
7. Immune Disease
• AIDS
Spread of Cancer
• 1. LYMPHATIC
• Most common
• 2. HEMATOGENOUS
– Blood-borne, commonly to Liver and Lungs
• 3. DIRECT SPREAD
– Seeding of tumors
PRTAHANAN TUBUH MELAWAN
TUMOR
• 1. T cell System/ Cellular Immunity
– Cytotoxic T cells kill tumor cells
• 2. B cell System/ Humoral immunity
– B cells can produce antibody
• 3. Phagocytic cells
– Macrophages can engulf cancer cell debris
DIAGNOSTIC
1. BIOPSY
– The most definitive
2. CT, MRI
3. Tumor Markers
GRADING
The degree of DIFFERENTIATION
• Grade 1- Low grade
• Grade 4- high grade
Cancer Staging
1. Uses the T-N-M staging system
• T- tumor
• N- Node
• M- Metastasis
2. Stage 1 to Stage 4
• Stage 0: A small group of cancerous cells have been found in
one location in the lung.
• Stage I: The cancer is only in the lung and has not spread
anywhere else.
• Stage II: The cancer has spread to nearby lymph nodes.
• Stage III: The cancer has spread to more distant lymph nodes,
and/or other parts of the chest like the diaphragm.
• Stage IV: The cancer has spread to other parts of the body
(distant metastasis).
