neoplasia Flashcards
“ALL” treatment induction therapy (children and adolescents)
children and adolescents: combo of
vincristine, desxamethosone and doxorubicin and L-asparaginase.
“ALL” treatment induction therapy (adults)
similar to children
But also with cyclophosphamide
“CLL” treatment (under 65)
under 65 yrs old:
- Fludarabine, cyclophosphamide, rituximab (FCR)
alternatively rituximab and bendamustine, if not FCR compliant.
“CLL” treatment (over 65)
over 65 yrs old:
Chlorambucil by itself
or with obinutuzumab
or if high risk patient then: ibrutinib
“AML” treatment
cytarabine
“CML” inital features and terminal stage
intial stage:
bone marrow hyperplasia
acumulation of differentiated myeloid cells in peripheral blood
terminal:
- rapid acuumulation of blast cells in bone marrow
- supression of normal hematopoiesis
CML 3 stages
chronic : less than 10% blasts in peripheral blood/bone marrow
accelerated: 10-29% blasts
blast crisis: more than 30% blasts
CML diagnosis
fever, weight loss, night sweats, anemia
- excess granulocytes
fatigue, bone pain, abdominal discomfort
proven therapy: HSCT
allogenic hematopoietic stem cell transplantation
other therapyL TKI-based therapy: can prolong “chronic phase”
hodgkins lymphoma risk factors
EBV infection (epstein barr virus)
reed sternberg cells
hodgkins lymphoma pathogenesis
Disruption of B-cell transcription process, preventing b cell surface marker expression and mRNA production
diagnosis of hodgkins lymphoma
biopsy of enalrged node
positron emission tomography (PET)
hodgkins lymphoma treatment
ABVD regimen
consits of:
doxorubicin, bleomycin, vinblastine, dacarbazine
for stage III/IV or CD30 positive: brentuximab vedotin in combo with AVD. not B
non-hodgkins lymphoma complications
bone marrow faillure
CNS infiltration
thrombocytopenia
non-hodgkins lymphoma treatment
R-CHOP
rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone.
common breast cancer symptoms
painless lump
discharge, warm skin, red skin, oedema.
metastatic spread symptoms: breathing difficulty, bone pain, hypercalcemia, jaundice.
breast cancer drug treatments and moa
1) tamoxifen:
moa: SERM that blocks estrogen receptors on breast cancer cells, inhibiting their growth.
2) anastrozole:
moa: reduces estrogen production
3) Capicasertib:
moa: targets protein kinase B, blocking cancer cell growth.
4) Trastuzumab:
moa: targets HER2 receptors, inhibiting their growth..
5) Zoledronic acid:
moa: Bisphosphonate that inhibits osteoclast-mediated bone resorption, reducing bone metastasis risk.
ovarian cancer symptoms
BEAT
Bloating that doesn’t go away
Eating difficulties
Aabdominal and pelvic pain
Toilet changes (bowel habits)
lab tests and imaging for ovarian cancer
FBC
liver and renal function test
imaging: abdominal ultrasonography, chest x ray, CT, MRI, PET scan
main type of prostate cancer
adenocarcinoma
risk level and grading of proastate cancer based on PSA levels
where 10ng/ml is low
10-20 moderate
20+ is high
examination for prostate cancer
digital rectal examination
advantages: safe and easy to perform
disadvantages:
- low sensitivity
- poor complinace
- subject to variability between different examiners.
prostate cancer symptoms
uretral dysfunction
frequent urination
hesitancy
dribbling
impotence
advanced disease:
back pain
bone pain
anemia
weightloss
oedemea
prostate cancer treatment
docetaxel
moa: inhibits microtubule depolymersiation, disrupting cell division
side effects: neutropenia, fatigue, neuropathy, alopecia, nausea, diarrhoea, nail changes.
prostate cancer monitoring and followups
check PSA level every 6 months for 5 years
Digital rectal exam as well
testicular cancer treatment
Bleomycin
moa: breaks DNA strands via free radical formation
side effects: pneumonitis, fever, skin changes.
monitor lung function
Etoposide:
moa: inhibits topoisomerase II, causing DNA damage.
side effects: hair loss, mouth sores, nausea, low blood counts.
monitor: bone marrow supression, kidney and liver function.
Cisplatin:
moa: crosslinks DNA, stopping cell division and replication causing cancer cell death.
side effects: nausea, vomiting, hearing loss, kidney toxicity
monitor: stay hydrated, kidney function
