Malignant skin tumors can be treated by CO2 laser excision or vaporization, neodymium: yttrium aluminum garnet (Nd:YAG) laser coagulation, and systemic or topical photodynamic therapy (PDT). Possible indications for CO2 laser vaporization include superficial basal cell carcinomas, actinic keratoses,
Synovial sarcoma is a rare mesenchymal neoplasm that is usually located in the limbs. Its occurrence in the head and neck region, and particularly in the larynx, is exceptional, with only 16 cases reported to date. Two histological variants have been described, a biphasic and a monophasic variant.
OBJECTIVE
Indocyanine green (ICG) is a clinically approved dye for diagnostic purposes, which has an absorption peak in the near infrared and remains intravascular due to a high plasma protein binding. Its therapeutic potential in combination with a diode laser was studied for well vascularized
BACKGROUND
Cutaneous lesions of Kaposi's sarcoma associated with acquired immunodeficiency syndrome (AIDS-KS) are disfiguring.
OBJECTIVE
This study assesses the response of AIDS-KS to pulsed-dye laser (PDL) therapy.
METHODS
The PDL was used to treat 15 AIDS-KS patients. Treatment was repeated at
Indocyanine green (ICG) is clinically approved for the determination of liver function, cardiac output and plasma volume. In this pilot study, ICG was used as photosensitizer in combination with a diode laser to treat AIDS-associated Kaposi's sarcoma (KS) in three patients. Directly and up to 50 min
We present the case of a 52-year-old male patient with recurrence of a soft-tissue sarcoma of the left leg treated with percutaneous laser ablation. The patient received the diagnosis of sarcoma for the first time in 2011; further local recurrences and a pulmonary metastatic spread occurred during
Hyperpigmentation of the skin is often refractory to conventional therapies, but has significant cosmetic implications if located on visible areas. Because laser systems are capable of removing pigment deposits caused by selective photothermolysis, we addressed the issue of whether the Q-switched
Laser activation of anthracycline-related drugs combines chemotherapy with photoablation for improved treatment. Hypericin, a structurally related anthraquinone, was tested for laser activation and cytotoxicity in human cancer cells. Viability of P3 squamous cell carcinoma cells incubated with 1 to
A chitosan derivative, glycated chitosan (GC), has been used as an immunostimulant for cancer treatment in laser immunotherapy. The function of GC is to enhance the host immune response after direct cancer cell destruction by a selective laser photothermal interaction. To further test its effects,
Quantitative binding of Rous sarcoma virus (RSV) of different antigenic subgroups to chicken cells was examined by using a laser flow cytometer/cell sorter. RSV of subgroups A, C, and E, labeled with the fluorescent membrane probe rhodamine-18, bound 2 to 10 times more to genetically susceptible
BACKGROUND
Treatment involving photosensitizers and laser irradiation (LIR) in cancer therapy is known as photodynamic therapy (PDT). The purpose of our study was to assess the therapeutic effect of PDT using rhodamine-123 (Rh123) and LIR on subcutaneous tumors (ST) in mice.
METHODS
Sarcoma-180
We treated patients with Kaposi's sarcoma of the lid or conjunctiva, molluscum contagiosum and papilloma of the lid with dye laser photocoagulation. This therapeutic device is extremely efficient as the chosen wavelength of 577 nm is absorbed selectively by haemoglobin. Since Kaposi's sarcoma is a
BACKGROUND
Kaposi sarcoma (KS) is a systemic disease that can present with cutaneous lesions with or without internal involvement, mostly caused by infection with human herpesvirus-8. The treatment options include surgical excision, cryotherapy, radiotherapy, intralesional chemotherapy, laser, and
The treatment of soft tissue sarcoma (STS) generally involves tumor excision with a wide margin. Although advances in fluorescence imaging make real-time detection of cancer possible, removal is limited by the precision of the human eye and hand. Here, we describe a novel pulsed Nd:YAG laser
Mice (C57BL/6) with established intradermal tumors (melanoma B-16 or glioma 203G1) and inbred Swiss mice (SWM/Ms) with established intradermal tumors (3-methylcholanthrene-induced sarcoma) were treated by either surgical excision or laser irradiation. Laser irradiation is effective in preventing the
