Efficacy of PDD-guided tumor excision combined with photodynamic therapy in cutaneous squamous cell carcinoma.

Background: Cutaneous squamous cell carcinoma (cSCC) is an aggressive tumor with unclear margins. Photodynamic diagnosis (PDD) enables the differentiation of tumor tissue from normal tissue via visible fluorescence. Photodynamic therapy (PDT) is widely used in the treatment of non-melanoma skin tumors.

Assessment of the efficacy and safety of auricular keloids excision followed by 5-aminolevulinic acid photodynamic therapy.

Background: Auricular keloids are a significant clinical challenge, which adversely affect the life of the patient at the level of aesthetic and psychological well-being. Despite various treatment modalities, a universally effective therapy has yet to be established. Photodynamic therapy (PDT) offers a promising approach by inhibiting the abnormal proliferation of fibroblasts while minimizing damage to surrounding healthy cells and tissues.

Increased CD56 expression after photodynamic therapy indicates an increased natural killer cell count following early photodynamic therapy for cutaneous squamous cell carcinoma.

Cutaneous squamous cell carcinoma (cSCC) is the second most common type of skin cancer. Photodynamic therapy (PDT) is a promising therapeutic method for managing cSCC due to its proven ability to target specific areas over time and its low risk of side effects. PDT may cause tissue damage and vascular shutdown, and may regulate local immunological responses.

PDD-guided tumor excision combined with photodynamic therapy in patients with extramammary Paget's disease.

Background: Photodynamic diagnosis (PDD) is a technique that plays a role in visualizing tumor size during the assessment of surgery. Photodynamic therapy (PDT) is a treatment apart from surgery, chemotherapy, radiotherapy, and immunotherapy that is approved for several types of tumors and nonmalignant diseases. The purpose of this study was to illustrate the efficiency and safety of PDD-guided tumor excision combined with ALA-PDT in patients with extramammary Paget's disease (EMPD).

Efficacy and safety of ALA-PDT in treatment of diabetic foot ulcer with infection.

Background: Diabetic foot ulcers (DFUs) with infection is a major clinical issue, as the infection not only potentially devastate the wound healing, but also is the factor that most often leads to amputation. Nevertheless, traditional antibiotic treatment is often insufficient to clear the infection, which could lead to side effects. Photodynamic therapy (PDT) has broad-spectral antibacterial activity.

A combination of preoperative or intraoperative MB-PDT and surgery in the treatment of giant cutaneous squamous cell carcinoma with infection.

Background: Giant cutaneous squamous cell carcinoma (cSCC) with infection is a major clinical issue, as the infection not only promotes the progress of tumor, but also effects the success of surgery. Traditional antibiotic treatment is not always sufficient to clear the infection, especially for cSCC infected with multidrug-resistant bacteria. Photodynamic therapy (PDT) has broad-spectral antibacterial activity and non-selective pressure, which makes it difficult to induce antibiotic resistance.

Clinical efficacy of Mohs surgery combined with topical photodynamic therapy for facial basal cell carcinoma.

Purpose: The purpose of this study is to investigate the clinical efficacy of Mohs surgery in combination with topical photodynamic therapy (PDT) for facial basal cell carcinoma.

Patients And Methods: Eighty-six patients with facial basal cell carcinoma treated in our department from April 2011 to December 2013 were included. Mohs surgery was used to remove the lesions followed by direct suturing, skin flap grafting, or medium thickness free-skin grafting to repair the incisions.

Ocular preservation through limited tumor excision combined with ALA-PDT in patients with periocular basal cell carcinoma.

Background: In recent years, photodynamic therapy (PDT) has emerged as a successful technique for treating early non-melanoma skin cancers compared with traditional methods such as surgical operation, chemotherapy, radiotherapy, and immunity treatment, etc. PDT offers excellent aesthetic results and skin function preservation effects, especially so for tumor in difficult-to-treat areas. The purpose of this article was to study the anti-tumor effect of ALA-PDT combined with limited excision in periocular basal cell carcinoma (BCC) and its role in improving the effect of the operation.

Treatment of verrucous carcinoma in penis with topical aminolevulinic acid photodynamic therapy: An effective and safe treatment method.

Background: Verrucous carcinoma of the penis is a rare disease characterized by verrucous lesions. The traditional treatment methods for verrucous carcinoma result in loss of sexual function are not satisfactory. The purpose of this study was to evaluate the safety and effect of topical aminolevulinic acid photodynamic therapy in the treatment of verrucous carcinoma in penis.
