Photodynamic Therapy (PDT) in Lung Cancer

2014-08-27 03:19:04 | BioPortfolio


This study is being done to determine whether a substance called hematoporphyrin can be used to treat tumors in various locations in the body when used in association with a laser. Hematoporphyrin is a substance that is taken up by cancerous cells. When these cells are exposed to the energy emitted by a laser source, chemical reactions occur in the cell and cause the cells to die. It is hoped that this treatment method may be able to selectively destroy malignant cells without damaging surrounding healthy tissue.


Lung cancer is currently the leading cause of death in both women and men in the United States and continues to be a major problem in several other countries in the world. Detection, localization, and surgical treatment at an early stage, provides the best opportunity for long-term survival for patients with non-sma11 cell lung cancer at this time. Studies examining the utility of screening patients at high risk for lung cancer with sputum cytology and chest roentgenograms showed that, despite a higher frequency of detecting and resecting early cancers in the screened group, there was no difference between the screened group and the control group in overall cancer mortality.

The purpose of this study is to determine if photodynamic therapy (PDT) is an alternative to surgical resection in patients with early stage) roentgenographically occult squamous cell carcinoma of the lung who are candidates for surgery. If PDT is successful, it would remove the indication for surgery and eliminate the need for an operation. The specific goals are to evaluate the impact of PDT on these patients by determining the percentage of patients who are spared surgery as wel1 as the following: morbidity, overall mortality, lung cancer mortality, the rate of subsequent lung cancer, the relative cost of PDT and surgery, the change in pulmonary function over time, the effect on quality of life, and the patient preferences for PDT and surgery.

Medical and Biotech [MESH] Definitions

The purified component of HEMATOPORPHYRIN DERIVATIVE, it consists of a mixture of oligomeric porphyrins. It is used in photodynamic therapy (HEMATOPORPHYRIN PHOTORADIATION); to treat malignant lesions with visible light and experimentally as an antiviral agent. It is the first drug to be approved in the use of PHOTODYNAMIC THERAPY in the United States.

Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.

A performance measure for rating the ability of a person to perform usual activities, evaluating a patient's progress after a therapeutic procedure, and determining a patient's suitability for therapy. It is used most commonly in the prognosis of cancer therapy, usually after chemotherapy and customarily administered before and after therapy. It was named for Dr. David A. Karnofsky, an American specialist in cancer chemotherapy.

Tumors or cancer of the LUNG.

A complex mixture of monomeric and aggregated porphyrins used in the photodynamic therapy of tumors (HEMATOPORPHYRIN PHOTORADIATION). A purified component of this mixture is known as DIHEMATOPORPHYRIN ETHER.
