Q

What is CAR-T therapy?

A

Therapy for ALL that removes T cells and trains them to attack neoplastic B cells. It is so effective that the B cells are killed so rapidly it causes cytokine storm.

28
Q

What lymphoma is amenable to surgical excision?

A

Hodgkin Lymphoma

29
Q

What is the most common lymphoma worldwide?

A

Diffuse Large B cell lymphoma

30
Q

Common presenting symptom in Diffuse Large B cell lymphoma?

A

Rapidly enlarging symptomatic mass

31
Q

Prognosis of Diffuse Large B cell lymphoma?

A

Not great, most patients present with advanced disease.

Curable in half of cases

32
Q

Second most common non hodgkin lymphoma

A

Follicular Lymphoma

33
Q

Painless peripheral adenopathy is a common symptom in what diagnosis?

A

Follicular lymphoma

34
Q

Follicular lymphoma has a good prognosis, but it can progress to what other types of lymphoma?

A

Diffuse Large B cell
or
Burkitt lymphoma

35
Q

What is a common location for a mass in Burkitt lymphoma?

A

Abdominal or retroperitoneal

36
Q

What medication should be prescribed to patients with Burkitt lymphoma before treatment and why?

A

Alopurinol
Burkitt lymphoma can cause tumor lysis syndrome, where large amounts of potassium, phosphate, and nucleic acids are released in circulation

37

A

Mantle Cell lymphoma

38
Q

Where does mantle cell lymphoma occur?

A

Any region of the GI tract

A

MALT (mucosa associated lymphoid tissue) lymphoma

40
Q

MALT lymphoma is what type of lymphoma?

A

Marginal zone lymphoma

41
Q

What lymphoma is associated with an IgM monoclonal gammopathy, Raynaud phenomenon, and smudge cells?

A

Lymphoplasmacytic lymphoma

42
Q

Why is non-hodgkin lymphoma not amenable to surgical excision?

A

It involves discontinuous groups of lymph nodes

43
Q

What organ is often involved with non-hodgkin lymphoma?

A

The spleen

44
Q

Multiple myeloma is a cancer of what type of cells?

A

Plasma cells (fully matured B cells that produce antibodies)

45
Q

You should consider multiple myeloma in a patient with what lab findings?

A

Anemia and hypercalcemia

46
