Tumour surveillance in Beckwith-Wiedemann syndrome and Hemihyperplasia (Hemihypertrophy)
This document is only valid for the day on which it is accessed. Please read our disclaimer.
There has long been a recognised relationship between disorders of increased somatic growth and predisposition to cancer.
Two related syndromes in particular are associated with cancer predisposition:
Isolated Hemihyperplasia (IHH)
Both are linked to a significantly increased risk of developing abdominal tumours, including Wilms Tumour (WT), hepatoblastoma and adrenal cell carcinoma.
Screening may result in early stage disease and smaller tumours being detected (8).
"Asymmetric overgrowth of one or more of the cranium, face, trunk and limbs, with or without visceral involvement" (13).
- HH of limbs involves discrepancy in both length and circumference of affected limbs.
- HH may affect segmental regions of the body or selected organs and tissues.
- There is no consensus about which regions of the body can be involved and the degree of asymmetry required to make the diagnosis (13).
- The asymmetry often becomes more pronounced with age. Growth rate usually slows around age 7-8 years.
- HH can be a feature of BWS or an isolated finding (IHH).
- The frequency of HH in the general population has been reported between 1:53,000 and 1:86,000. The frequency is 2.01:100 among children with Wilms tumour.
- For children with HH, the risk of WT is approximately 3% (3).
- Neoplasia (WT/hepatoblastoma/adrenal cell carcinoma) risk for HH has been reported as 5.9% (7).
- Children with HH were (1993) less likely (32%) to be diagnosed with HH before the diagnosis of WT, but with raised awareness HH is often diagnosed first (3)
Beckwith-Wiedemann Syndrome (BWS)
- The incidence of BWS has been estimated to be 1:13,700 births with 85% sporadic and 15% familial (5). For children with BWS, the risk of neoplasia has been reported between 7.5% (1) and 21% (5) and is highest in the first decade of life (6)
- Several studies have demonstrated that children with both BWS and HH have a higher risk (40%) of WT than children with either condition alone (1,6,10)
- Children with BWS screened for WT were much less likely (0 /12) to present with advanced disease than those who were not screened (25/ 59)(8), potentially allowing for nephron sparing surgery (11).
- Screening for abdominal tumour (renal,adrenal,hepatic,pancreatic) by regular abdominal ultrasound examination is recommended for children with BWS, HH, or both. A scan interval of 3-4 months is recommended, as interval tumours have been reported with scan intervals in excess of 4-6 months (2). This is due to the rapid Wilms Tumour growth rate with a doubling time estimated between 11-40 days (9,13).
- Various surveillance protocols for these children have been proposed with the aim to reduce morbidity and mortality from cancer in children with BWS and isolated HH.
- Surveillance is targeted at detecting embryonal tumours, particularly Wilms tumour and hepatoblastoma. Screening of serum alpha-fetoprotein is recommended in children with BWS or IHH to detect hepatoblastoma.
There are no serum tumour markers that will detect Wilms Tumour (12).
Recommendation for screening in IHH and BWS (13-15)
|Tumour surveillance||Frequency||Until age|
|Abdominal ultrasound||3 monthly||0-4 years|
|Renal ultrasound||3 monthly||4-8 years|
|Serum alpha-fetoprotein||3 monthly||4 years|
|Complete physical examination including abdominal palpation by a physician||6 monthly ^||Indefinite|
