EUS-FNA for Retropharyngeal Lymph Node (RPLN) in Recurrent Nasopharyngeal Carcinoma (NPC) Patients

Phase 2
Conditions
Nasopharyngeal Carcinoma
Interventions
Procedure: EUS-FNA for RPLN in NPC patients
Registration Number
NCT03006588
Lead Sponsor
Sun Yat-sen University
Brief Summary

EUS-FNA for RPLN in NPC

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).

Recruitment & Eligibility

Status
UNKNOWN
Sex
All
Target Recruitment
100
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
