NICE guidance for suspected haematological cancers
– Primary healthcare professionals should be aware that haematological cancer can present with a variety of symptoms that may have a number of different clinical explanations.
– Combinations of the following symptoms and signs may suggest haematological cancer and warrant full examination, further investigation (including a blood count and film) and possible referral: – Fatigue - bleeding – recurrent infections - drenching night sweats – bone pain - fever – alcohol-induced pain - weight loss – abdominal pain - generalised itching – lymphadenopathy - breathlessness – splenomegaly - bruising
![Page 5: Diagnosis and patient pathway in lymphomas · The Royal Marsden Change Presentation title and date in Footer dd.mm.yyyy 1 Diagnosis and patient pathway in lymphomas Dr Ian Chau Consultant](https://reader030.vdocuments.site/reader030/viewer/2022041201/5d48d28688c993f7368bb254/html5/thumbnails/5.jpg)
What would be your initial investigations in patients with unexplained lymphadenopathy?
– A) Full blood count – B) Ultrasound of the lymph node – C) ESR – D) Serum rheumatoid factor – E) Monospot test
Vote 1 for A, B and C Vote 2 for A, B, C and D Vote 3 for all the above Vote 4 for A, B, C and E Vote 5 for A, D and E

Investigation and referral of lymphadenopathy (NICE guidance)
– Investigation of patients with unexplained lymphadenopathy should include a full blood count, blood film and erythrocyte sedimentation rate, plasma viscosity or C-reactive protein (according to local policy).
– Any of the following additional features of lymphadenopathy should trigger further investigation and/or referral:
– persistence for 6 weeks or more
– lymph nodes increasing in size
– lymph nodes greater than 2 cm in size
– widespread nature
– associated splenomegaly, night sweats or weight loss.

How common is lymphadenopathy in general population?
– 1) 6% – 2) 10% – 3) 1% – 4) 60% – 5) 0.6%
![Page 8: Diagnosis and patient pathway in lymphomas · The Royal Marsden Change Presentation title and date in Footer dd.mm.yyyy 1 Diagnosis and patient pathway in lymphomas Dr Ian Chau Consultant](https://reader030.vdocuments.site/reader030/viewer/2022041201/5d48d28688c993f7368bb254/html5/thumbnails/8.jpg)
Background to lymph node diagnostic clinic (LNDC)
– Lymphadenopathy (LA) is common affecting patients of all ages.
– An annual incidence of 0.6-0.7% has been estimated for the general population
![Page 9: Diagnosis and patient pathway in lymphomas · The Royal Marsden Change Presentation title and date in Footer dd.mm.yyyy 1 Diagnosis and patient pathway in lymphomas Dr Ian Chau Consultant](https://reader030.vdocuments.site/reader030/viewer/2022041201/5d48d28688c993f7368bb254/html5/thumbnails/9.jpg)
Background
– Criticial tasks are:
– differentiate benign from malignant lymph nodes
– identify serious medical conditions that require specific treatment
– reassure patients with benign reactive lymphadenopathy (BRL) or self-limiting disease
![Page 10: Diagnosis and patient pathway in lymphomas · The Royal Marsden Change Presentation title and date in Footer dd.mm.yyyy 1 Diagnosis and patient pathway in lymphomas Dr Ian Chau Consultant](https://reader030.vdocuments.site/reader030/viewer/2022041201/5d48d28688c993f7368bb254/html5/thumbnails/10.jpg)
Factors in assessing lymphadenopathy
– General factors such as age, sex, socio-economic conditions
– Sites of lymph nodes
– Associating symptoms and signs
– Epidemiological clues such as occupational exposures, recent travel or high risk behaviours
![Page 11: Diagnosis and patient pathway in lymphomas · The Royal Marsden Change Presentation title and date in Footer dd.mm.yyyy 1 Diagnosis and patient pathway in lymphomas Dr Ian Chau Consultant](https://reader030.vdocuments.site/reader030/viewer/2022041201/5d48d28688c993f7368bb254/html5/thumbnails/11.jpg)
Background
– Cancer is perhaps the disease people fear most
– In primary care setting, the prevalence of malignancy were 0-1.3%
– This compared with lymph node biopsies series with malignancy rate as high as 40%
– Serious non-malignant conditions presenting with LA
– Infections such as TB and HIV
– Immune induced injury disorders such as SLE, sarcoidosis and rheumatoid arthritis
![Page 12: Diagnosis and patient pathway in lymphomas · The Royal Marsden Change Presentation title and date in Footer dd.mm.yyyy 1 Diagnosis and patient pathway in lymphomas Dr Ian Chau Consultant](https://reader030.vdocuments.site/reader030/viewer/2022041201/5d48d28688c993f7368bb254/html5/thumbnails/12.jpg)
Primary aim of lymph node diagnostic clinic (LNDC)
– Current referral pattern varies
– Lymph node diagnostic clinic was set up to reach rapid diagnosis in a concerted multidisciplinary approach in patients with lymphadenopathy
![Page 13: Diagnosis and patient pathway in lymphomas · The Royal Marsden Change Presentation title and date in Footer dd.mm.yyyy 1 Diagnosis and patient pathway in lymphomas Dr Ian Chau Consultant](https://reader030.vdocuments.site/reader030/viewer/2022041201/5d48d28688c993f7368bb254/html5/thumbnails/13.jpg)
Results
– N=550 patients
– Median age was 40 (range 14-90)
– Median time between initial referral and first clinic visit was 6 days (including weekends and public holidays)
– 75% seen within one week of referral and 97% within two weeks.

right flank and abdomen while on holiday in Barbados – Pain recurred after returning to the UK – Consulted GP – US → gallstones and abdominal lymph nodes – June 2012 Underwent laparoscopic cholecystectomy
and lymph node biopsy – Retroperitoneal mass biopsy, liver biopsy and gall
bladder only showed chronic active cholecystitis and previous fat necrosis (histology reviewed at RMH)

Conclusions
– Lymphadenpathy has a wide range of causes – both beneign and malignant
– Persistent, supraclavicular and multiple regions are features suspicious of malignant lymphadnopathy
– Many lymphomas do not present with lymphadenopathy
– High cure rate in some lymphomas and the indolent nature of other lymphomas mean treatment toxicities (short and long term) need to be carefully balanced with treatment efficacy
