Q

Describe how cancer cells spread through the body.

A
  • growing into or invading nearby normal tissue
  • moving through the walls of nearby lymph nodes or blood vessels
  • travelling through lymphatic system and bloodstream to other parts of the body
  • stopping in small blood vessels in a distant location, invading the blood vessel walls, and moving into the surrounding tissue
  • growing in this tissue until a tumour forms
  • causing new blood vessels to grow, which creates a blood supply that allows the tumour to continue growing

Acute: rapid onset of symptoms with death in weeks to months without treatment
Chronic: insidious onset over years

32
Q

How does acute myeloid leukaemia happen?

A

Cells of the leukaemic clone proliferate but typically don’t mature, these blasts (immature precursors) then take over the bone marrow causing anaemia and thrombocytopenia

How does the cell lineage of Hodgkin v Non Hodgkin lymphoma differ?

A

The neoplastic cell in Hodgkin disease is always of B cell lineage
The neoplastic cell in non Hodgkin lymphoma may be of B, T or NK cell lineage

46
Q

How would you treat Hodgkin’s Lymphoma?

A
  • Early stage, low-risk disease can be offered 2-4 cycles of chemotherapy (doxorubicin, bleomycin, vinblastine and dacarbazine ABVD) foolowed by radiotherapy. 90% are cured.
  • Advanced disease patients (stages 3 or 4) are typically offered 6-8 cycles of ABVD chemotherapy followed by irradiation of bulky sites. 50-60% will have a median survival in excess of 5 years.
  • Haematopoietic stem cell transplant may be considered for patients with refractory or relapsed disease
