Treatment
Medical Care
The objective of care is to detect and to prevent malignant change. The presence of the white plaque alone does not require treatment.
- Several management regimens have been suggested; however, no large trials have shown a definitive, reliable treatment. No evidence base exists on which to reliably recommend treatment. Indeed, current evidence suggests that no treatment is of reliable benefit.
- Possible courses of action include the following:
- Wait and watch
- Medical therapies (eg, anti-inflammatory agents, vitamins, cytotoxic agents)9
- Surgical removal (eg, scalpel, laser, cryoprobe, electrosurgery, photodynamic therapy)
- Patients should avoid any causal factor, such as use of tobacco and alcohol. Leukoplakias can regress under these circumstances.
- Any degree of dysplasia in a lesion at a high-risk site must be taken seriously and the lesion should be removed.
- Occasionally, patients are treated by photodynamic therapy or topical cytotoxic agents.
- Patients should be examined regularly, probably at 3- to 6-month intervals.
Surgical Care
Management of leukoplakias is far from satisfactory, and no large trials offer guidance as to the most reliable treatment. Surgical removal of leukoplakia seems one reasonable option. Some experts surgically remove these lesions with scalpel, laser, or cryoprobe. Laser excision is preferred to fulguration.10,11 Others point out the possible aggravation of dysplasia caused by such operative intervention and that surgical removal of aneuploidic lesions does not improve mortality rates.12

Diet
A diet rich in fresh fruits and vegetables may help prevent cancer.
Medication
Retinoids are currently being investigated as a possible treatment modality. They appear to be very effective but can have severe adverse effects on liver function and may cause teratogenicity. Their beneficial effect appears to last only during the treatment.
Retinoids
These agents decrease the cohesiveness of abnormal hyperproliferative keratinocytes and may reduce the potential for malignant degeneration. They modulate keratinocyte differentiation. They have been shown to reduce the risk of skin cancer formation in patients who have undergone renal transplantation.
Isotretinoin (Accutane)
Oral agent that treats serious dermatologic conditions. Synthetic 13-cis isomer of the naturally occurring tretinoin (trans- retinoic acid). Both agents are structurally related to vitamin A. In acne, its activity includes reduction in sebaceous gland activity, modification of keratinocytic adhesion, and anti-inflammatory actions.
If used to treat acne, at least 8 wk should be allowed between courses of treatment if re-treatment is indicated (because of possible continued improvement).
Prescriber and patient must enroll in FDA-sponsored iPledge system to receive this medication. Difficult to prescribe for off-label use (nonacne), especially because iPledge system does not allow use beyond 5- to 6-mo period.
Adult
500 mcg/kg PO qd with food for 4 wk
Pediatric
Not established
Toxicity may occur with vitamin A coadministration; pseudotumor cerebri or papilledema may occur when coadministered with tetracyclines; may reduce plasma levels of carbamazepine; alcohol may increase toxicity; topical agents that are drying and/or irritating may potentiate cutaneous adverse effects
Documented hypersensitivity; pregnancy and breastfeeding
Pregnancy
X - Contraindicated; benefit does not outweigh risk
Precautions
If possible, avoid in women of childbearing age; if used (only for severe acne), the patient must be using 2 forms of birth control 1 mo before, during, and 1 mo after treatment (blood donors taking this drug should not donate blood during treatment and for 1 mo after this treatment has been stopped); may decrease night vision; hepatitis may occur; occasionally, exaggerated healing response of acne lesions (excessive granulation with crusting) may occur; transient exacerbation of acne may occur during initial period of treatment requiring reduction of dose and/or systemic corticosteroids; patients with diabetes may experience problems in controlling blood sugar and plasma triglyceride concentrations while on isotretinoin; caution in patients with preexisting or family history of hypertriglyceridemia
Avoid exposure to UV light or sunlight until tolerance has been achieved; with prolonged use (especially in treatment for disorders of cornification), skeletal abnormalities, including diffuse interstitial skeletal hyperostosis in adults and premature closure of the epiphyses in children, may occur; rarely, depression and attempts of suicide have occurred while taking this drug; laboratory monitoring includes CBC count, fasting blood lipids, hepatic function tests, and bhCG (for pregnancy); comprehensive metabolic panel/SMA-12 and blood sugar level have also been suggested
