microscopic prostate
non melanoic non metastatic skin
21
Q

malignancy CI to CRT?

A

MM
uncontrolled CA
CA colon Duke D
CA breast stage III

22
Q

PTLD common time?

A
1st year (median 18m) after CRT
EBV- generally late (>5yr)
23
Q

PTLD risk factors?

A

organ: kidney 1%, 33% in SB / multiple organ
Age: common in children
IC use: CNI, mTOR protective ? but conflicting results
MMF / AZA unrelated
ATG increase risk but not IL2 / CD52 alemtuzumab
balatacept (costimulatory blocker) CI if EBV-
EBV D+R-
HCV+

24
Q

PTLD sym?

A

fever, night sweat, weight loss
respi: tonsillar / gingival, lung infection, mass
GI: diarrhea, pain, perforation, bleeding, mass
LN
CNS

25
Q

PTLD Tx?

A

reduce or off MMF, CsA, FK
? mTOR switch
RTX
chemo if above 2 unresponsive, aggressive, CHOP based
surgery +/- RT for local disease
Acyclovir / ganciclovir unproven benefit
adoptive immunotherapy with EBV specific T cell new

26
Q

prognositc factor of PTLD?

A

poor WHO performance status 3-4 (chairbound), late onset disease, high LDH, CNS disease, severe organ dysfunction, AKI at diagnosis, T cell disease

27
Q

prevention of PTLD?

A

? monitor EBV and preemptive IC reduction +/- ganciclovir
? RTX to prevent transmission D+R-
prophylactic antiviral not useful

28
Q

BCC / SCC more common in CRT?

A

SCC

29
Q

CA after CRT Mgt?

A

CNI to mTOR or CNI minimization with mTOR
metastatic cancer IC change probably futile and increase rejection
mTOR switch useful in skin cancer / RCC but other CA unknown
