What adverse reactions can Trastuzuma cause?

34
When is the surgical review following surgery?
Surgical review on anniversary of surgery then discharge from clinic follow-up

Bone mets
38
What should you do to the bone with pain?
Localised CT of the bone

Admit to oncology urgently !!
44
What therapy causes hot flushes?
This occurs with oestrogen blockers e.g Tamofixen
45
What drug can help with hot flushes?
Clonidine
46
What should be done if hot flushes get really bad?
** Stop oestrogen blockage if it gets really bad **
47

Merina coil
48
In breast cancer patients, when can the marina coil be used?
Keep in if patient has bad periods or needs for contraception
49
What are the 2 main tumour markers of breast cancer?
* CEA | * CA15-3
50
What are the below good for? * CEA * CA15-3
Good for monitoring disease | Bad for diagnosing disease
51
When only should you check ...? * CEA * CA15-3
Don’t check these unless you know that the patient has metastatic disease
52
** If someone on this gets PV bleeding, always consider the risk of endometrial cancer or polys !! **
If on Tamofixen
53
What is the link between breast size and radiotherapy?
The bigger the breast, the greater the damage
54
When does damage from breast radiotherapy usually happen?
This usually happens at the end of treatment or once the treatment has stopped
55
What is a new lump post treatment usually?
Fat necrosis NOTE: unlikely to be recurrence unless really aggressive cancer
56
What is common in cancers with multiple bone mets?
Spinal cord compression
57
What should be done if you think someone has spinal cord compression?
MRI
58
What are the most common cancers to cause bone mets?
** Prostate, lung and breast are most common cancer to cause mets **
