Q

What is the presentation of ALL?

A

2-3 weeks history bone marrow failure or bone/joint pain

Infection, sweats

6
Q

What investigations are done for ALL?

A

FBC
Bone marrow aspiration
LP if CNS involvement

7
Q

What is the standard treatment of ALL?

A

Chemo- indiction, consolidate and maintenance

CNS directed treatment

8
Q

What is the treatment for high risk ALL?

A

Standrad therapy + Stem cell transplant

9
Q

What newer therapies are available for ALL?

A

Bispecific T cell engagers

CAR T cells

10
Q

What are CAR T cells?

A

Genetically engineered T cells that have certain receptors to attack cancer

11

What are the possible side effects of CAR T cells?

A

Cytokine release syndrome

Neurotoxicity

12
Q

What are the symptoms of cytokine release syndrome?

A

Fever
Hypotension
Dyspnoea

13

What symptoms can neurotoxicity in CAR T cell therapy cause?

A
Confusion
Seizure
HEadahe
Focal neurology
Coma
14
Q

What are the indicators for a bad prognosis in ALL?

A
Increasing age
Increased WCC
Immunophenotype
Molecular genetics
Slow/poor response to treatment
15

19
Q

What is the staging of CLL?

A

What is the treatment of CLL?

A

Watch and wait
Cytotoxic chemo
Monoclonal antibodies
Novel agents

23
Q

What gives CLL a bad prognosis?

A
Advanced disease
Atypical lymphocyte morphology
