Introduction: Light-driven cancer therapy strategies (e.g. photodynamic therapy and photothermal therapy) have undergone remarkable progress in recent years, but they still suffer from a serious drawback of limited penetration depth of light in tissue. As a non-invasive and non- ionizing radiation, ultrasound can be focused remotely, transferring acoustic energy deep in the bo...

two rare cases of extra-articular diffuse variant giant cell tumor of the tendon sheath are presented, at the elbow of a 68-year-old female and the foot of a 56-year-old male. both patients presented with a palpable masses and marginal excision was performed; histological sections confirmed the diagnosis of extra-articular giant cell tumor. no adjuvant therapy was administered. at the last foll...

Acoustic cavitation which occurs at high intensities of ultrasound waves can be fatal for tumor cells. The existence of dissolved gases and also the presence of nanoparticles (NPs) in a liquid, irradiated by ultrasound, decrease the acoustic cavitation onset threshold and the resulting bubbles collapse. On the other hand, due to unique capabilities and optical properties of gold nanoparticles (...

Tumor cells may be eliminated by increasing their temperature. This is achieved via photothermal therapy (PTT) penetrating the tumor tissue with near-infrared light and converting energy into heat using agents. Copper sulfide nanoparticles (CuS NPs) are commonly used as PTAs in PTT. In this review, we aimed to discuss synergism between PTT CuS NPs other therapies such chemotherapy, radiotherapy...

epithelioid hemangioendothelioma is a vascular tumor with an intermediate malignant potential. this tumor is very rare in the lung parenchyma, and most of the previously reported cases have been asymptomatic. there is no standard therapy for this tumor and prognosis in the previous reports has been variable. herein we report our experience with a 60-year-old woman presenting with hemoptysis and...

herein we report a case of primary leiomyosarcoma of testis, which was believed to originate from normal testicular structures.  it contained smooth muscle cells, blood vessels and contractile cells of the seminiferous tubules.  no evidence of tumor spread was found. treatment consisted of orchiectomy with high ligation of the spermatic cord.  the patient received no adjuvant therapy and there ...

Background: Recent studies in eye plaque brachytherapy have shown a considerable difference between the dosimetric results using water phantom and a model of human eye containing realistic materials. In spite of this fact, there is a lack of simulation studies based on such a model in proton therapy literatures. In the presented work, the effect of utilizing an eye model with ocular media on pr...
