Canada, Neurosurgery, and 5-Aminolevulinic Acid (5-ALA): The Long and Winding Road

Photodynamic Detection of Peritoneal Metastases Using 5-Aminolevulinic Acid (ALA)

In the past, peritoneal metastasis (PM) was considered as a terminal stage of cancer. From the early 1990s, however, a new comprehensive treatment consisting of cytoreductive surgery and perioperative chemotherapy has been established to improve long-term survival for selected patients with PM. Among prognostic indicators after the treatment, completeness of cytoreduction is the most independen...

5-Aminolevulinic Acid (5-ALA): Analysis of Preclinical and Safety Literature

Problem: 5-ALA has been used for many years at relatively high dose amounts in single doses for photodynamic therapy and immunofluorescence of tumors. An analysis of compiled data relating to safety and any side-effects about the use of 5-ALA at low doses has not yet been published. Purpose: This report analyzes data about the safety of the use of 5-Aminolevulinic Acid (5-ALA) in low doses as a...

5-aminolevulinic acid (5-ALA) fluorescence-guided Mohs surgery resection of penile-scrotal extramammary Paget's disease.

This report aims to evaluate the usefulness of 5-aminolevulinic acid (5-ALA) fluorescence-guided Mohs surgery resection of penile-scrotal extramammary Paget's disease for achieving maximum tumor resection. Between January 2014 and December 2015, 5 patients underwent surgical resection of a penile-scrotal extramammary Paget's disease in department of urology, Huashan hospital, Fudan University. ...

Antitumor effect of combination of hyperthermotherapy and 5-aminolevulinic acid (ALA).

BACKGROUND 5-Aminolevulinic acid (ALA) is a precursor of heme. ALA is used as a photosensitive substance in photodynamic diagnosis (PDD) and photodynamic therapy (PDT) because heme metabolism is abnormal in tumor cells and a photosensitive metabolite of heme synthesis from ALA, protoporphyrin IX (PpIX), specifically accumulates in tumors. We investigated the enhancement of the antitumor effect ...
