How do you stage lymphomas? [1]
Lecture content
PET scans
Describe the additional clinical features of HL than lymphadenopathy [5]
Pel-Ebstein fever
- cyclical fever followed by periods of being afebrile for 1-2 weeks (rare)
Abdominal pain (if abdominal lymphadenopathy is involved)
Pruritus (30%)
Clinical hepato/splenomegaly is rare (although liver and spleen involvement determined by laparoscopy/laparotomy occurs in up to 30% of the patients)
Bone marrow involvement (5-8%)
systemic - ‘B symptoms’ (25%)
* weight loss
* pruritus
* night sweats
* fever (Pel-Ebstein)
Describe the Cotswolds-modified Ann Arbor staging system for HL [5]
Stage I - limited to a single lymph node region.
Stage II - two or more lymph node regions involved, on the same side of the diaphragm.
Stage III - lymph node regions involved on both sides of the diaphragm.
Stage IV - spread to other organs, such as liver, spleen, or bone marrow, with or without nodal involvement.
Each stage is followed by a letter:
- A - without B symptoms.
- B - with B symptoms, including fever, weight loss, night sweats.
- E - an extra-nodal site involved, that is localised to the known lymph node region.
- X - bulky disease: mediastinal mass exceeds 1/3 of the intrathoracic diameter or nodal mass >10cm in dimension.
Describe the treatment plan for Stage I/II classical Hodgkin’s lymphoma [2]
and
Stage III/ IV classical Hodgkin’s lymphoma [2]
Stage I/II classical Hodgkin’s lymphoma:
- Chemotherapy followed by radiotherapy
- Main treatment regimen: ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) + radiotherapy
Stage III/ IV classical Hodgkin’s lymphoma:
- Chemotherapy alone: ABVD or BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisolone)
Describe the treatment plan for Stage I/ II nodular lymphocyte-predominant Hodgkin’s lymphoma: [1]
and
Stage III/ IV nodular lymphocyte-predominant Hodgkin’s lymphoma [2]
Stage I/ II nodular lymphocyte-predominant Hodgkin’s lymphoma:
- Involved-field radiotherapy alone is the main treatment for this group of patients with excellent clinical benefit.
Stage III/ IV nodular lymphocyte-predominant Hodgkin’s lymphoma:
- R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone) is administered in symptomatic patients or those with rapid disease progression .
- Regular monitoring is adequate in asymptomatic patients.
Describe the management plan for HL in refractory disease [2]
Chemotherapy followed by autologous stem cell transplantation (ASCT)
Immunotherapeutic agents can be considered:
- Brentuximab vedotin
- nivolumab
- pembrolizumab
Describe the common complcations of HL [6]
Complications of Hodgkin’s lymphoma are usually chemotherapy or radiotherapy related.
Thyroid:
- Around 50% of the patients who received radiotherapy experience symptoms of hypothyroidism.
- thyroid cancer and hyperthyroidism also possible
Chemotherapy drugs,: especially alkylating agents are associated with secondary malignancies:
- acute myeloid leukaemia
- paraneoplastic syndrome
Cardiac abnormalities:
- doxorubicin are at a higher risk of developing cardiomyopathy
- acute pericarditis shortly after receiving radiotherapy
- valvular heart disease or coronary heart disease in the long-term after radiotherapy
Pulmonary toxicity:
- bleomycin-related pulmonary toxicity
- Radiation-induced pneumonitis
Infertility :(
Infections:
- Neutropenia is common in patients taking chemotherapeutic regimens such as ABVD, and almost all patients receiving BEACOPP are neutropenic.
How do you differentiate between leukaemia and lymphoma from a FBC? [1]
Leukaemias tend to have high circulating serum WCCs
Lymphomas tend not to have circulating cells; have solid tumours; enlarged LN with high WCC
