<strong>Improving</strong> Outcomes <strong>for</strong><br />

People <strong>with</strong> Skin Tumours<br />

<strong>including</strong> Melanoma<br />

Management of special<br />

groups<br />

Observational studies that address the risk of <strong>melanoma</strong> arising from<br />

congenital melanocytic naevi (CMN) report that children <strong>with</strong> large<br />

CMN are at greatly increased risk of cutaneous and non-cutaneous<br />

<strong>melanoma</strong>, warranting continuous surveillance. Larger CMN pose a<br />

greater risk than smaller lesions. Small CMN (< 10 cm in largest<br />

diameter) are considered precursors to epidermal <strong>melanoma</strong> which<br />

largely occurs after puberty. Giant nevi (> 20 cm in largest diameter)<br />

pose a risk <strong>for</strong> dermal <strong>melanoma</strong> predominantly in pre-pubescent<br />

children, although these naevi may also produce epidermal<br />

<strong>melanoma</strong>s after puberty.<br />

Lymphoma<br />

Clinical guidelines and expert reviews support the opinion that<br />

patients <strong>with</strong> cutaneous lymphoma should be managed by an MDT.<br />

One RCT demonstrated that early intervention in mycosis fungoides<br />

using multi-agent chemotherapy does not improve survival but does<br />

increase morbidity.<br />

Clinical guideline evidence supports avoidance of toxic or aggressive<br />

therapies in the treatment of patients <strong>with</strong> early-stage disease. Skindirected<br />

treatment (topical therapy, superficial radiotherapy and<br />

phototherapy) has been shown to achieve long periods of remission<br />

and is the most appropriate therapy in early-stage disease.<br />

Five-year survival varies according to lymphoma type and is<br />

estimated to be 70–90% in patients <strong>with</strong> mycosis fungoides and<br />

10–50% in patients <strong>with</strong> Sézary syndrome. The quality of life of<br />

patients <strong>with</strong> cutaneous lymphoma may be severely affected over<br />

many years.<br />

Kaposi’s sarcoma<br />

Two expert reviews found that HAART is associated <strong>with</strong> a dramatic<br />

decrease in the incidence of KS and can bring about tumour<br />

regression. One observational study found that HAART is associated<br />

<strong>with</strong> prolonged disease control in patients <strong>with</strong> KS.<br />

Expert review evidence reports that local therapies <strong>including</strong><br />

cryotherapy, radiotherapy and topical treatments are effective <strong>for</strong><br />

treating patients <strong>with</strong> early <strong>skin</strong> lesions and that, in general, systemic<br />

chemotherapy <strong>for</strong> KS is a treatment option <strong>for</strong> patients <strong>with</strong><br />

widespread, symptomatic disease.<br />
