Summary Invasive anal cancers are generally successfully treated by combined chemotherapy with radiation therapy (XRT). For those patients who locally fail this intervention many are salvaged by surgery which generally results in permanent colostomy.

Photodynamic therapy (PDT) is a tumor-ablative and function-sparing oncologic intervention. The relative simplicity of photosensitizer application followed by light activation resulting in the cytotoxic and vasculartoxic photodynamic reaction has all

Nutrition and Orthomolecular Supplementation in Lung Cancer Patients

Autor: Claudio Sibata, D Campos, Ron R. Allison, C Austerlitz, Helion Póvoa

Publikováno v: Integrative Cancer Therapies. 8:398-408

This article reviews updates and provides some data related to nutritional and orthomolecular supplementation in oncology patients with an emphasis on lung cancer, a commonly diagnosed tumor with significant nutritional disturbances. Cancer and its t

Can efficiency of the photosensitizer be predicted by its photostability in solution?

We have investigated a possible correlation between the photostability and photodynamic efficacy for different photosensitizers; hematoporphyrin derivatives and chlorines. To perform such analysis, we combined the depth of necrosis (d nec) measuremen

Photofrin® photodynamic therapy: 2.0mg/kg or not 2.0mg/kg that is the question

Autor: Claudio Sibata, Ron R. Allison

Publikováno v: Photodiagnosis and Photodynamic Therapy. 5:112-119

Summary Photodynamic therapy (PDT) is an innovative minimally invasive therapy that has great potential for both tumor ablation and normal tissue preservation. However, while in recent years the standards of surgery, radiation and chemotherapy have d

The vials filled with Fricke solutions were doped with increasing concentrations of Photogem®, used in photodynamic therapy. These vials were then irradiated with low-energy X-rays with doses ranging from 5 to 20 Gy. The conventional Fricke solution

Aggregation susceptibility on phototransformation of hematoporphyrin derivatives

Autor: Priscila Fernanda Campos de Menezes, Hidetake Imasato, Juliana Carvalho Ferreira, Claudio Sibata, Janice Rodrigues Perussi, V. S. Bagnato

Publikováno v: Laser Physics Letters. 5:227-235

Photosensitizers used in PDT suffer degradation by light. In this work, photobleaching of Photogem® (PG), Photofrin® (PF), and Photosan® (PS), hematoporphyrin derivatives, were induced by light in the presence or absence of 1% Triton X-100. The de

Photostability of different chlorine photosensitizers

Autor: Claudio Sibata, Cristina Kurachi, Priscila Fernanda Campos de Menezes, Ron R. Allison, Juliana Carvalho Ferreira, V. S. Bagnato

Publikováno v: Laser Physics Letters. 5:156-161

In this paper, we report the photodegradation of three different chlorine photosensitizers (Photoditazine®, Radachlorin®, and Foscan®). The photosensitizer degradation was analyzed by changes in the fluorescence spectrum during illumination. The r
