1
Q

A 48 year old man is presents to the GP with an enlarged lymph node on one side of his neck.

What would you ask?

A

When he first noticed it and progression over time - size, shape, consistency, mobility, tenderness

Pain in the node and anything that makes it worse e.g. alcohol in Hodgkins

Any other enlarged lymph nodes anywhere else?

B sxs- e.g WL, night sweats, fever
Itching - common in haem maligancy due to cytokine release

Recent hx of infection - less likely with unilateral nodes but consider dental issues

PMH - transplant (post transplant lymphoproliferative disorders - PTLD)

Q

How could you explain to a patient why chemotherapy causes neutropenia?

A

chemotherapy destroys rapidly dividing cells like cancer cells

can therefore destroy other cells that divide very quickly like the lining of your mouth (mucositis) and also you cells that fight infection

Q

What diagnostic test would you do for a patient with a suspicious enlarged lymph node but no systemic sxs?

What other tests may be useful at this stage?

A

excisional lymph node biopsy
(USS of the lymph node if low suspicion of lymphoma)

FBC for bone marrow involvement + infection
CRP, ESR
LDH - for disease burden and cell turnover

Screen for EBV, Hepatitis (surface antigen and core antibody), HIV - for other causes of lymph node enlargement and also because hepatitis can react to monoclonal antibody treatments

CT neck, chest, abdo, pelvis for staging / spread if higher suspicion of lymphoma

SC midazolam

can give levetiracetam for seizure prophylaxis - can titrate quickly and can give in a SCSD

A

they can’t drive

67
Q

How can brain mets be managed?

A

very generalised rule of thumb:
< 2 may qualify for surgery
>2 = radiotherapy

68
Q

What dose of metoclopramide would you give a cancer patient with N+V?

A

30 mg before meals

69
Q

Dexamethasone is the first line steroid for most acute onc presentations e.g. MSCC and brain mets.

In what situation might you use another?

A

prednisolone is first line for pneumonitis / colitis due to immunotherapy

Give some causes of RUQ pain in cancer patients

A

Hepatic mets
