French ENT Society (SFORL) guidelines for the management of immunodeficient patients with head and neck cancer of cutaneous origin

ObjectivesThe French ENT Society (SFORL) created a workgroup to draw up guidelines for the management of immunodeficient patients with head and neck cancer of cutaneous origin. The present guidelines cover diagnostic and therapeutic management and prevention of head and neck cancer of cutaneous origin in immunodeficient patients, and in particular in transplant patients and those with HIV infection.Materials and methodsThe present guidelines were based on a critical multidisciplinary reading of the literature. Immunosuppression and its varieties are defined. The usual risk factors for skin cancer and those specific to immunodeficiency are presented. The prevention, assessment and management of cutaneous carcinoma, melanoma, Kaposi's sarcoma and lymphoma are dealt with. The level of evidence of the source studies was assessed so as to grade the various guidelines. When need be, expert opinions are put forward.ResultsImmunodeficient patients are at higher risk of head and neck skin tumors. The level of risk depends on the type of deficiency; there is an especially high risk of squamous cell carcinoma in transplant patients and of Kaposi's sarcoma in HIV-positive subjects. Various viruses are associated with skin cancers. Skin tumors are often evolutive in case of immunodeficiency, requiring rapid treatment. Management is generally the same as in immunocompetent subjects and should be discussed in a multidisciplinary team meeting. Immunosuppression may need to be modulated. In organ transplant patients, the only class of immunosuppressants with proven antitumoral efficacy are mTOR inhibitors, particularly in cutaneous squamous cell carcinoma. The rhythm of clinical surveillance should be adapted according to the risk of recurrence. Preventive measures should be undertaken.ConclusionSkin cancers in immunodeficiency are highly evolutive, requiring the earliest possible treatment. Immunosuppression may need modulating. As the risk of recurrence may be elevated, careful surveillance should be implemented. Preventive measures should also be undertaken.
