11.2 Management of keratinocyte cancer risk in organ transplant recipients

From Clinical Guidelines Wiki
Clinical practice guidelines for keratinocyte cancer > 11.2 Management of keratinocyte cancer risk in organ transplant recipients


Background

Australian organ transplant recipients (OTRs) are at increased risk of developing keratinocyte cancers (KCs) due to iatrogenic immunosuppression, with a high burden of disease.[1]

Strategies for managing KC risk in patients who have undergone organ transplant include a combination of primary prevention and, treatment of established disease. Australian guidelines since 2008 have recommended that this care be provided in transplant-dedicated specialist clinics, where possible.

Specific treatment strategies include:

  • systemic acitretin chemoprophylaxis
  • reduction in immunosuppression
  • treatment with mechanistic target of rapamycin kinase (MTOR) inhibitors.

Overview of evidence (non-systematic literature review)

Primary prevention of keratinocyte cancer

Skin cancer prevention in OTRs should begin before transplantation, with education about how immunosuppressive medication will raise their risk of cutaneous squamous cell carcinoma (cSCC) and basal cell carcinoma (BCC). This should emphasise the need constantly to protect themselves from high sun exposure after transplantation and include education about sun avoidance, especially in the middle of the day, sunscreen use[2] and protective clothing.

A study conducted among OTRs in Queensland found that their use of sun protection measures was suboptimal.[3] The findings of international and Australian studies show that ongoing advice and encouragement about sun protection, given in a clinical setting, appear to be especially effective in achieving behaviour change among people undergoing organ transplantation.[4][5]

Chemopreventive medicines, including acitretin, capecitabine and vitamin B3 (nicotinamide), have been used to reduce KC risk in people undergoing organ transplantation.[6][7][8] However, none of these are established as part of routine preventive care for OTRs.

Role of transplant-dedicated dermatology clinic

The importance of integrated specialist care in the management of skin cancer in organ transplant recipients has been widely recognised.

The various models of care described include:

  • transplant-dedicated dermatology subspecialty clinics[9][10]
  • multidisciplinary transplant clinics[9]
  • existing dermatology clinics where transplant care is integrated[9]
  • high-throughput skin cancer surgery and surveillance clinics for high-risk OTRs[11]
  • nurse-led surveillance clinics with consultant dermatologist support[12][13][14]

The type of clinic adopted is influenced by available resources.

The UK National Institute for Health and Care Excellence (NICE) recommends that all OTRs be followed up in transplant-dedicated specialist dermatology clinics.[15] The transplant-dedicated dermatology clinic typically comprises dermatologists and dermatologic surgeons with consultation from plastic surgeons, head and neck surgeons, medical oncologists and radiation oncologists as needed.[10] Transplant physicians may consult simultaneously in some clinical settings,[9] and close collaboration with transplant physicians is essential in all clinic models, to co-ordinate care and negotiate adjustments to immunosuppression and commencement of systemic chemoprophylaxis, such as with oral acitretin.

Efficient scheduling of transplant-dedicated specialist clinics increases accessibility, accommodating timely excision of multiple lesions and access to emergency visits.[9][11] Adequate time and staffing can be allocated to provide surgical management on the day of assessment when appropriate, streamlining care for patients who already commit a significant amount of time to medical appointments, and so facilitating adherence and follow-up (see: Importance of adherence to keratinocyte cancer screening, below).[11][16]

Dermatology assessment prior to transplantation aims both to treat identified disease and to assess risk, guiding physicians in the timing of transplantation and determining when transplantation may be relatively contraindicated.[9][17]

The regular surveillance and proactive approach adopted by these clinics promote early detection and treatment, with the aim of improving prognosis and minimising cost. A prospective cohort study of high-risk OTRs followed over 22 years determined that surveillance every 4 months was required to ensure <15% of cancers developed before the subsequent review.[18] Recommendations from this study included 3-monthly reviews for patients who had developed two or more skin cancers and more frequent reviews for those with high-risk tumours or new cancers arising before 3 months, in agreement with other studies. [2][16][17] Patients who were cancer-free for 12 months could be reviewed annually.[18]

Dedicated transplant dermatology clinics provide an opportunity for reinforcing tailored education regarding photoprotection[5] and skin-self surveillance. Education early in the post-transplantation period using multiple methods has been shown to improve long-term retention and behavioural change.[19][20][21]

Multidisciplinary care by a team of specialists who understand the unique care needs of OTRs allows for shared decision-making and continuity of care. These clinics also facilitate research[9] and provide opportunities for teaching dermatology trainees who may provide care to OTRs in peripheral settings. [17]

Importance of adherence to keratinocyte cancer screening

Adherence to screening recommendations has an important effect on clinical outcomes among OTRs. A population-based cohort study of 10,183 OTRs in Canada reported that high adherence to annual dermatology assessments was associated with a 34% reduction in KC-related morbidity or death, compared with low adherence.[22]


Key point(s)
  • Organ transplant recipients should be educated about sun-protection measures and regularly encouraged to practise them.
  • Where resources permit, patients undergoing organ transplant should be offered preventive and ongoing care for keratinocyte cancers within dedicated specialist clinics. Where access to dedicated clinics is not available, organ transplant recipients need to be closely and regularly monitored for skin cancer, especially those with previous skin cancer.
