ENB and Photodynamic Therapy in the Treatment for Early Lung Cancer

July 9, 2017 updated by: National Taiwan University Hospital

The Application of Electro-magnetic Navigation Bronchoscopy (ENB) and Photodynamic Therapy in the Treatment for Early Lung Cancer

With the increased incidence of lung cancer and prevalence of low dose CT screening, treating of early lung cancer has becoming an important issue in the clinical practice of thoracic oncology. In this clinical study, the investigators will evaluate whether superDimension (superD) ENB (Electromagnetic navigation bronchoscopy) in combination with interstitial photodynamic therapy can provide the chance of tumor eradication.

Detailed Description

Lung cancer is the one the major cause of cancer death all over the world especially in Asia. The prevalence of low dose CT screening has made more patients of lung cancer treated in the early stage. The treatment of choice for of early lung cancer is surgical resection. However, several difficulties exist in surgery for treating early lung cancer. eg. Some presenting as multi-focal lesions, which cannot be completely eradicated by surgical resection.

Electromagnetic navigation bronchoscopy (ENB)（superDimension™ Navigation System, super-D ENB) is a novel technique, which uses an image guided localization system to direct steerable bronchoscopic tools to predetermined points within the bronchial tree. This technology allows improved access to peripheral lesions in particular.

Photodynamic therapy (PDT) has been adopted an effective treatment option for the central located lung cancer by using photosensitizer which is focally retained in the tumor leading to tumor-specific abrasion by irradiating with a certain wave-length of light. The most frequently used and commercially available photosensitizer for lung cancer is PDT with Photofrin under 623 nm red light irradiation. For the peripheral lung cancer which cannot be approached by bronchoscopy, interstitial PDT with the aids of CT guided catheter implantation has been adopted. However, there are potential disadvantages of such approach including 1) bleeding or hemothorax during CT-guided catheter implantation; 2) dislodging of the catheter after lung collapse in the procedure; 3) unable to treat other lesion after pneumothorax.

In the current proposal, the investigators use ENB in combination with PDT to handle to test the feasibility of super-D ENB guided-PDT to treat small lung cancer which cannot be eradicated through surgical resection.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

16 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Multiple small lung cancer which cannot be completely removed by surgical resection.
  2. Patient with small early lung cancer with diameter less than 1 cm and with high surgical risk precluding surgery.
  3. Patient with small early lung cancer with diameter less than 1 cm but unwilling to receive surgical intervention.
  4. Age above 20 years old and who can do the bronchoscopy test

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: super-D ENB guided-PDT
To test the feasibility of super-D ENB guided-PDT to treat small lung cancer which cannot be eradicated through surgical resection.
Procedure: super-D ENB guided-PDT
PDT with super-D EBN localization will be given for treating the target lung lesion. Intrvenous photofrin (2mg/kg) will be given 48 hours before intervention. After localization of the tumor by ENB, a 630nm of light will be give for the lesion with the dosage of 2oo J/cm. Intravenous general anesthesia and endobronchial intubation will be performed under the whole procedure.

What is the study measuring?

Primary Outcome Measures
