Oncology Flashcards
When to cease a cancer drug due to SE
If SE impacting function
Spindle cells
GIST
CTLA-4 inhibitor
Ipilimumab
PD-1 inhibitor
Pembrolizumab
Nivolumab
Serum marker elevated in testicular Ca
b-HCG
AFP in non-seminoma
Cancers associated with BRAF mutation
Melanoma
CRC less commonly
Risk of breast cancer with BRCA
70%
BRCA screening
MRI / ultrasound yearly from 30
Mammogram after 50
Breast ca screening
2 yearly 50 -74
Patients that qualify for axilalry dissection - Early breast cancer
> 2 LN
High risk breast Ca
HER positive
ER negative
Tamoxifen
Eosteogen receptor blocker
Increased DVT/PE
Uterine Cancer
SSRI reduces active tamoxifen (fluoxetine or parole tube)
Treat for 5 years unless high risk
Aromatase inhibitor SE
Block conversion if androgen to oestrogen
Post menopausal women
Menopause
Arthralgia
Accelerated osteoporosis
Raised AFP
Non seminona
Chemo for testicular cancer
Bleomycin
Etoposide
Cisplatin
TTF1 cancer association
Adenocarcinoma
MEN-1 cancer association
parathyroid gland, anterior pituitary, and enteropancreatic
C-RET cancer assocaition
medullary thyroid cancer
FAP screening
Annual sigmoidoscopy from age 12 years
Two yearly gastroscopy from 25 years as gastric and duodenal polyposis
Risk factors for Trastuzumab cardiac toxicity
Previous or concurrent anthracycline use and age greater than 50 years are the strongest risk factors
Location of CTLA-4
T Cell - interacting with APC
Location of PDL-1
Tumour cell
Drugs that respond well to immunotherapy
Microsatellite-repair (MSI) high tumours
High mutation burden
Melanoma, NSCLC, Bladder, Lung small cell, oesophageal
Prognostic marker for immunotherapy for melanoma
High Baseline LDH has poor prognosis
CDK4/6 inhibitor indicates
Metastatic
HER 2 negative
Hormone receptor positive
Cheyne stokes breathing
Heart failure
Treatment of limited stage 1 Small cell lung cancer
- Resetion and LN sampling
2. Adjuvent chemo with 4 cycles cisplatin based therapy
Treatment of extensive disease small cell lung cancer
- 4 cycles platinum based chemotherapy
2. Radiotherapy if good response to chemotherapy
Rx stage I or II NSCLC
- Resection (lobectomy and LN resection) or steroatactic ablative body radiation with curative intent (if not suitable for surgery)
- Adjuvent cisplatin chemotherapy
Rx Stage III NSCLC
- Surgical resection
- Chemo
- RT
- Immunotherapy with darvalumab if no progression
Rx Stage IV NSCLC
Driver mutation absent
Low PD-L1 expression
- Chemotherapy (platinum-based doublet)
2. Supplemental Immunotherapy (Pembrolizumab/bevacizumab)
Rx Stage IV NSCLC
Driver mutation absent
High PD-L1 expression (>50%)
Immunotherapy first line with pembrolizumab
Rx Stage IV NSCLC
Driver mutation: EGFR
Osimertinib
Osimertinib
MOA/SE
MOA: EGFR- TKI that selectively inhibits EGFR-TKR-sensitising and EGFR T790M resistant mutations
SE: Aceneiform rash (correlated with treatment response) - steroids
Diarrhoea, ocular, pulomnary, alopecia
