How does fluorouracil cause chest pain?
How can this be prevented?
Vasospasm, some metabolites are cardiotoxic
Angiogram and stenting prior to chemo
What sort of chemo is Cisplatin/carboplatin/Oxaliplatin?
Side effect?
How does this occur?
Which one is most likely to have side effects?
Platinum based chemo
Peripheral neuropathy - acute and chronic
Oxaliplatin
Effects on voltage gated sodium channels
Intrathecal methotrexate causes what CNS side effect?
What is the timeframe for this to occur?
Prevention?
Aseptic meningitis
2-4hrs post injection
Corticosteroids
What does the MEN2A gene cause?
What is the percentage risk?
Predisposition to medullary thyroid cancer (MTC), pheochromocytoma, and primary parathyroid hyperplasia.
90 percent for MTC, approximately 40 to 50 percent for pheochromocytoma, and 10 to 20 percent for multigland parathyroid hyperplasia.
What is the difference between MEN2A and MEN2B?
What gene is implicated in both?
MEN2A - Medullary, phaeo and parathyroid tumours
MEN2B - Medullary + Phaeo tumours, NOT parathyroid, instead Neuromas + marfanoid
Gene = RET
Treatment for medullary thyroid cancer?
What mutation do you need to confirm this?
What other tumours should you look for?
How do you monitor recurrence?
Thyroidectomy before age 20
RET mutation
Phaeo + parathyroid
Calcitonin level
What type of HPV infection is highly oncogenic?
What cancers is it associated with?
HPV infection type 18: Along with type 16
associated with cervical and other anogenital cancers, as well as some head and neck cancers.
What type of tumour most commonly causes SIADH?
Small cell lung cancer
What type of cancer can cause gynaecomastia?
How does this occur?
Testicular cancer
B-HCG produced by tumour activates LH receptors on testes, this increases testosterone release and excess testosterone is converted into oestrogen by aromatase in peripheral tissues
An adolescent 16 year old female has been treated successfully with radiotherapy for Hodgkin’s disease.
Which of the following tumour is most likely to occur when she reaches adulthood (After more than 10 years following treatment)?
Non-hodgkins
Thyroid
Breast
Acute Leukaemia
Ovarian
Breast cancer
Which biomarker is the most independently predictive of immune check point inhibitor induced myocarditis?
BNP
CK
Troponin
CK-MB
CK-MB
What tumours are linked to the below markers?
Which one predicts overall prognosis with normalisation?
Beta-HCG
CEA
Ca19.9
CA-125
CA15.3
Beta-HCG - Testicular
CEA - Colorectal
Ca19.9 - Pancreatic
CA-125 - Ovarian
Ca15.3 - Breast
Beta-HCG levels are linked to prognosis i.e. decreased levels post treatment = good survival
What are the 1st, 2nd and 3rd line therapies for early clear cell RCC disease?
What about advanced disease?
What is more common: clear cell or spindle cell?
1st - Sunitinib
2nd - Bevacizumab
3rd - Nivolumab
Advanced = Ipi/Nivo
Most common = clear cell
What is first line treatment for immune-mediated colitis?
Second line?
High dose glucocorticoids
Second line is Anti-TNF alpha therapy
Which of the following is a good prognostic marker of Sunitinib therapy?
Why?
Pyrexia
Diarrhoea
Flu-like symtpoms
Myalgia
Hypertension
Hypertension
Sunitinib is a VEGF TKI, so when its working it acts on vasoendothelial cells causing vasoconstriction and hence hypertension
When is Pembrolizumab used in high risk Renal cell carcinomas;
Pre or post op?
Post resection
What is the most common side effect of Bleomycin?
What are the risk factors?
What DLC0 change prompts immediate cessation?
Is there blood eosinophilia?
Pulmonary toxicity
Higher dose, renal failure, exposure to high dose oxygen, smoking
DLCO decrease >25%
Eosinophil = no
What is the leading cause of death for survivors of testicular tumors following successful chemotherapy?
Second primary cancers
Lung fibrosis
Renal failure
Myocardial ischaemia
Thromboembolic event
Second primary cancers
What is the difference in side effects between Ifosfamide and Cyclophosphamide ?
Ifos = Acute Nephritic syndrome
Cyclo = hemorrhagic cystitis
Which of the following medication has been associated with cases of male breast cancer?
Finasteride
Metoprolol
Spironolactone
Acetazolamide
Doxazosin
Finasteride
Which of the following cancers have the best chance of long term survival even with the presence of metastasis?
Treatment?
- prostate cancer with bone metastases
- ovarian cancer with malignant ascites.
- lung cancer with brain metastases.
- breast cancer with bone metastases
- germ cell cancer with lung metastases.
Germ cell with lung
Treatment = cisplatin, etoposide and bleomycin.
Which of the following gene mutation is associated with increased risk of breast cancer in males?
BRCA 2
BRCA 1
RET
CHEK 2
P53
Mutations in both BRCA1 and BRCA2 genes are associated with an increased risk of breast cancer in males, but the BRCA2 mutation carries a higher risk for male breast cancer compared to BRCA1.
Men who carry mutations in the BRCA2 gene have a significantly increased risk of developing breast cancer compared to the general population. The lifetime risk of male breast cancer in BRCA2 mutation carriers is estimated to be approximately 68%, which is markedly higher than in men without these mutations.
