What Healthcare Professionals Should Know

Recommendations for the prevention of cutaneous toxicities with Multikinase inhibitor therapies are based on practices utilised in clinical studies, post-marketing experience and reports and empirical results based on clinical experience, including those of the authors. In all instances, patient education is an important component of management.

Rash

Frequent monitoring for rash, particularly at the beginning of therapy, may be useful. Preventive measures, such as regular use of alcohol-free emollients from the start of treatment, use of mild soaps, and avoiding extreme temperatures and direct sun exposure, may help prevent or reduce the severity of rash.1,2

Hand-Foot Skin Reaction

 A complete examination of hands and feet prior to starting treatment may ensure that any changes associated with HFSR are better identified.1 Patients with hyperkeratotic areas at baseline may be given a pedicure using sterile instruments prior to the start of the therapy.2–5 Prevention should include cushioning callused areas and the application of moisturising and keratolytic creams to control any existing palmar and plantar hyperkeratosis. During the first 2 to 4 weeks of treatment, it is vital to minimise the development of blisters by avoiding vigorous exercise and other activities that place stress mainly through friction on the hands and feet, including avoiding tight-fitting footwear.6,7 Orthotic devices to normalise weight-bearing and prevent friction may also be considered.3,8

Dry Skin and Pruritus

Possible triggers of Pruritus should be investigated by considering the patient’s medical history together with a thorough clinical assessment.5 Based on the expert’s experience, moisturising is an essential component of preventing Xerosis and pruritus, and use of moisturisers that are free of possible irritants is prudent.

Nail Changes

Preventive strategies include wearing comfortable shoes, putting on gloves while cleaning,3 keeping the hands dry as much as possible, minimising friction or pressure on the nail fold, avoiding picking or manipulating of the nail, and applying petrolatum around the nails to retain moisture.9 Patient education regarding appropriate clipping of the nail plates appears to be also beneficial, including avoidance of cutting the lateral margins of the nail plate shorter than the digit tip.

Stomatitis

An oral care plan should be developed before treatment and evaluated periodically,3 taking into account such factors as use of a soft toothbrush or swab; regular rinsing with an alcohol-free mouthwash, saline solution or bicarbonate; eating soft, room-temperature foods and avoiding hot, spicy or acidic food and drinks; and keeping a good oral hygiene.1,10

Photosensitivity

For multikinase inhibitors associated with photosensitivity, regular application of sunscreen with a sun protection factor (SPF) of at least 30 is required.2 Protective clothing and hats should be worn when outside.

Keratoacanthomas and Squamous Cell Carcinomas

Patients should be exhaustively explored at baseline and regularly monitored for the development of lesions as the treatment with the drug advances in order to ensure early and appropriate treatment.5,11 Inclusion of dermatologists as part of a multi-disciplinary team to help in early diagnosis is advised, especially in those patients that have presented a history of intense and frequent sun exposure.
