Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Detailed Description

To evaluate the safety and efficacy of a novel minimally invasive sampling technique -- fine needle aspiration (FNA) guided by endoscopic ultrasound (EUS), which aims to sample tissues from retropharyngeal lymph nodes (RPLN) for the diagnosis of patients with suspected recurrent nasopharyngeal carcinoma (NPC).

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

18 years to 75 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  1. had undifferentiated, non-keratinizing carcinoma at the initial diagnosis (WHO, 1991 criteria) and no evidence of distant metastasis obtained before radiotherapy;
  2. received regular chemotherapy with cytotoxic agents such as cisplatin, carboplatin, 5-fluorouracil, paclitaxel, etc, and coordinated with radiotherapy with standard doses (approximate 50-70 Gy) in nasopharynx and neck respectively. Within 3 months after radiotherapy, no local and distant lesions were found;
  3. during regular follow-up , the enlarged RPLN was detected by MRI more than 6 months later since radiotherapy accomplished;
  4. didn't receive chemotherapy radiotherapy, immunotherapy or salvage surgery from completion of radiotherapy to suspicious recurrent lesion in RPLN detected;
  5. no recurrent lesion in nasopharynx was found by white light endoscopy as well as cancer cell negative in pathology by bite biopsy;
  6. single lesion in RPLN, and no other recurrent or metastatic lesion was found in local region or distant organ.
  7. the minimum axial diameter of RPLN was more than 5mm.

Exclusion Criteria:

  • (1) patients with nasal stenosis; (2) patients with coagulation dysfunction; (3) patients with distant metastasis

EXPERIMENTAL: EUS-FNA for RPLN in NPC patients
Fine needle aspiration guided by EUS in retropharyngeal lymph node in suspicious recurrent naspharyngeal carcinoma.
Procedure: EUS-FNA for RPLN in NPC patients
An EUS probe was introduced to nasopharynx and the retropharyngeal space (RPS) were scanned. The suspicious recurrent RPLN, which was characterized as (1) roughly round and homogeneously hypo-echoic lesion in RPS; (2) located anterior to the carotid sheath which contained the internal carotid artery (ICA) and the internal jugular vein (IJV). Subsequently, guiding by EUS, a dedicated 22G needle was used to puncture into the enlarged RPLN, then the aspiration was conducted The entire EUS-FNA procedure was repeated at least three times till the satisfied strip tissue was obtained. The obtained tissue samples were sent for pathologic detection and the supernatant fluid was for thinprep cytologic test (TCT).

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2014

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
