The present invention relates to a method for treating disseminated superficial actinic porokeratosis (AK) or disseminated superficial actinic porokeratosis (DSAP). [Background technology]

[0003] Skin diseases are the most common human illnesses, affecting 30% to 70% of the population and potentially The rates are even higher in high-risk subpopulations (Hay RJ et al., J Invest Dermatol.2014.134(6):1527-1534) The medical burden was similarly significant, with direct medical costs estimated at nearly $27 million and lost An additional $11 billion in productivity is estimated. (Lim HW et al. J Am Acad Dermatol.2017;76:958-972).

[0004] Acne is the most common skin disease. Non-inflammatory acne is the most common type, and milia Inflammatory acne is usually caused by bacteria (P. acnes ( It is associated with P. acnes infection and is characterized by papules, pustules, nodules, and cysts. The most common triggers for both types of acne are hormonal, and many Many people experience at least a mild form of acne during adolescence. Other triggers include diet, smoking, and Treatments may include stress and certain medications. Acne often affects appearance at a critical age. This can have a negative impact on quality of life. (Kligman AM. J Invest Dermatol.1974;62:268-87).

[0005] topical medications for treating acne, such as benzoyl peroxide, retinoids, and antibiotics; Various methods are known. (Thiboutot D, et al. J Am Acad Dermatol.2009;60(Suppl 5):S1-50). Antibiotics, Systemic medications, such as thrombocytopenic and hormonal therapy, may also be used, although these approaches Many of these have undesirable side effects and / or do not produce acceptable results. Antibiotic resistance is on the rise, with over 50% of P. acnes Many countries have reported that strains of B. nescifera are resistant to certain topical medications.

[0006] Ultraviolet (UV) / blue light is mildly effective due to its anti-inflammatory effects mediated on skin cells. It is approved by the U.S. Food and Drug Administration (FDA) for the treatment of mild to moderate acne. The combination of photoactivators and high-intensity red light has proven effective, but (Hongcharu W, et al., J Invest D ermatol.2000 Aug;115(2):183-92),Sakamoto FH et al.,J Am Acad Dermatol.2010 Aug;6 3(2):183-93);(Sakamoto FH et al.J Am Aca d Dermatol.2010 Aug;63(2):195-211). As a result, This approach has been reserved for the most severe cases of acne. [Prior art documents] [Non-patent literature]

(iii) administering a dose of light to the affected area; Thereby, the method comprises treating the skin disease or disorder.

[0093] Skin diseases and disorders The skin diseases or disorders treated by the methods of the present invention can vary. In some embodiments, the skin disease or disorder is a cancerous lesion, a precancerous lesion, or acne. Areas of skin that can be treated include the head, face, neck, arms, legs and torso, hands and feet ( In certain embodiments, the area to be treated includes a portion of skin on the skin of the feet. , head, face, neck or parts thereof.

[0094] Actinic keratosis. In one embodiment, the skin disorder to be treated according to the methods of the present invention is In certain embodiments, the precancerous lesion is actinic keratosis (AK). AK (also known as actinic keratosis) is the most common precancerous skin lesion. Actinic keratosis lesions are often multifocal, appearing as crusty, scaly growths. Generally, they are about 2mm to 7mm in diameter. AK lesions range in color from skin-like to reddish. The color may vary from pale to pale and is often hyperkeratotic.

[0095] AK is typically caused by excessive exposure to ultraviolet (UV) light. In the United States, AK can be caused by overexposure to X-rays. These lesions can be: Typically on areas exposed to the sun, such as the face, head (hairless scalp), ears, shoulders, neck, arms, forearms, and hands In certain embodiments, the disease or disorder treated according to the methods of the present invention is AK on the face, neck or parts of these.

[0096] In one embodiment, the methods of the present invention are used to treat precancerous lesions other than actinic keratosis. In certain embodiments, the methods of the present invention are used to treat skin conditions other than actinic keratosis. It is used to treat a disease or disorder.

[0097] Non-melanoma skin cancer. In another embodiment, a skin disorder treated according to the methods of the present invention is a cancerous lesion. In certain embodiments, the cancerous lesion is a non-melanoma skin cancer (NMSC). Non-melanoma skin cancer includes all types of cancer that occur within the skin and are not melanoma. The most common types of NMSC are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). BCC and SCC are sometimes referred to as "keratinocytes" to distinguish them from melanoma. It is also called "keratinocyte carcinoma."

[0098] Basal cell carcinoma arises from the basal keratinocytes of the epidermis, hair follicles, and eccrine sweat glands. 80% of cases develop from this type of cell, usually on the head and neck (approximately 90%). They usually grow slowly (e.g., 1–2 cm over several years) and cannot spread to other parts of the body. These are rare (0.0003-0.05%). Through the irregular growth of sexual, finger-like extensions, the tumor invades tissue in a three-dimensional manner. Proliferating tissue is present at the outer edge of the lesion, while in the central region, cell apoptosis and subsequent regeneration occur. It is accompanied by ulceration.

[0099] The clinical features of BCC depend on the subtype: nodular BCC ("classical basal cell carcinoma"); ), is the most common subtype (more than 60% of cases), Appears as a dark brown nodule with curled edges, superficial telangiectasias, and ulceration or crusting .

[0100] Superficial BCC accounts for up to 20% of cases and occurs on the trunk in sun-protected areas. It appears as pink scaly patches or thin plaques, so it is considered superficial BC. C is Bowen's disease, psoriasis, discoid eczema, or tinea corporis Pigmented BCC occurs more commonly in patients of Far Eastern origin and can result in It may be mistaken for nodal melanoma. Morphea (sclerosing) BCC (cicatricial basal cell (also known as carcinoma) has the poorest prognosis and appears as subtle, scar-like plaques and vague Has a margin.

[0101] Histologically, BCC can be undifferentiated or differentiated. Undifferentiated BCC typically has These include pigmented BCC, superficial BCC, sclerosing BCC, and invasive BCC (histological subtypes) Nodular BCC is usually differentiated. Other forms of differentiated BCC include These include keratinizing BCC, BCC with sebaceous differentiation, and adenoid BCC. Types of biopsies that can be used to determine the histologic subtype of BCC include shave biopsy and and punch biopsy.

[0102] In one embodiment, the method of the present invention is directed to undifferentiated BCC, more particularly superficial BCC. It is used to treat

[0103] In another embodiment, the methods of the present invention are directed to differentiated BCC, more particularly nodular BCC. It is used to treat

[0104] In an exemplary embodiment, the BCC treated according to the methods of the present invention is a mixed histology BCC. have a histological pattern, i.e., contain two or more major histological patterns.

[0105] BCC is primarily caused by cumulative exposure to UV light, although it may also occur if the patient has not previously been exposed to radiation. It can also occur in subjects who have had previous exposure. Elderly people and men are at increased risk. Other risk factors include burn scars, smallpox scars, xeroderma pigmentosum, and basal cell nevi. After developing a BCC, patients are at risk for developing subsequent BCCs at other sites. increases significantly.

[0106] In one embodiment, the methods of the present invention can be used to treat BCC. In embodiments, the method is for the treatment of nodular, micronodular, cystic, invasive, superficial, pigmented , erythroderma ulcer (also known as "Jacobi ulcer"), Pi Concussive fibroepithelioma, polyploid, pore-like or aberrant The present invention can be used to treat BCC selected from the group consisting of: ant) ​​BCC.

In an embodiment, the lesion is in a low-risk location and is 20 mm or larger in size; Located in a medium risk location and measuring 10 mm or more; or Located in a high risk location and and 6 mm or more in size. Also, in terms of the boundary, i.e., the boundary is well defined. Lesions may be considered high risk because they are not recurrent or are recurrent.

[0114] About 20% of skin cancers are caused by squamous cells – the flat, scale-like cells that make up most of the epidermis. SCC is more likely to spread to other parts of the body than BCC, but less likely to spread than melanoma. It's much less propagable.

[0115] The most common risk factor, like BCC, is cumulative exposure to UV radiation. Risk factors include light skin color (e.g., blue eyes, blonde hair), chemical carcinogenesis, chronic radiation dermatitis, and H Includes PV, xeroderma pigmentosum and oculocutaneous albinism.

[0116] SCC may arise de novo or may be preceded by actinic keratosis (AK) There is a known conversion rate of about 0.0003% to about 0.05%. AK is present only in a portion of the epidermis. Histologically, AK is distinguished from SCC. SCC in situ is a full-thickness epidermal tumor. It is characterized by sharply demarcated, erythematous, scaly papules or plaques. Invasive SCC also involves penetration of the epidermal basement membrane, resulting in an indurated, scaly papule. Invasive SCC is characterized by moderately or poorly differentiated tumors or plaques. They may be classified, and the degree of differentiation correlates with invasiveness.

[0117] In one embodiment, the methods of the present invention can be used to treat SCC. In an embodiment, the SCC is preceded by an AK.
