Resumen
Objetivos

Evaluar, en pacientes venezolanos, la respuesta terapéutica del carcinoma basocelular al ser tratados con terapia fotodinámica usando un compuesto fotosensibilizador derivado de las clorinas.

Métodos

Se incluyen en el estudio pacientes con carcinoma basocelular único o múltiple diagnosticado por histopatología en adultos, sin discriminación de sexo o localización de la lesión, a quienes se les inyectó por vía intravenosa el fotosensibilizador Photolon. Después de un tiempo de tres horas, se iluminó la zona o zonas tumorales con un diodo láser de longitud de onda de 662nm.

Resultados

Se trataron 43 lesiones en 16 pacientes con una respuesta favorable en todos los casos tratados, con desaparición de cualquier evidencia clínica del o los tumores, lo cual se comprobó histopatológicamente. Los pacientes no presentaron complicaciones atribuibles al tratamiento y permanecieron en control sin evidencia de enfermedad oncológica por 24 meses.

Conclusiones

Se demostró la eficacia y utilidad de la terapia fotodinámica con Photolon para tratar pacientes venezolanos con lesiones múltiples de carcinoma basocelular.

Abstract
Objective

To evaluate therapeutic response, among Venezuelan patients, to photodynamic therapy for basal-cell carcinoma with a chlorine-based photo-sensitizer compound.

Methods

Patients included in the study had been diagnosed with single or multiple basalcell carcinomas, based on histopathology for adults, without gender or lesion localization discrimination, and were injected intravenously with the photo-sensitizer, Photolon. After a 3-hour interval, the tumoral zone (or zones) was illuminated with a 662nm wave length diode laser.

Results

Treatment was performed on 43 lesions in 16 patients with favorable response in every case; all clinical evidence of tumor(s) disappeared, which was confirmed by histopathology. Patients presented no complications attributable to treatment and remained under observation with no signs of oncologic disease for 24 months.

Conclusions

The efficiency and utility of photodynamic therapy with Photolon was demonstrated in the treatment of Venezuelan patients with multiple basal cell carcinoma lesions.
