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

Although concurrent chemoradiation is the standard treatment modality for locally advanced nasopharyngeal carcinoma (NPC), high incidences of distant metastases and severe treatment related toxicities have become an obstacle to be overcome. Besides, a common problem in locally advanced NPC is the narrow gap between the tumor and critical normal structures, which makes dose optimization difficult. Considering that significant tumor shrinkage may occur during induction chemotherapy, and incidences of distant metastases may be reduced by adjuvant chemotherapy, this study was designed to explore the efficacy and safety of sequential chemoradiotherapy with regimen of docetaxel, cisplatin and fluorouracil and reduced target delineation and radiation doses IMRT for patients with locoregionally advanced NPC.

Experimental: Reduced Target Delineation and Radiation Doses
All patients were assigned to receive induction chemotherapy (IC) followed by IMRT with adjuvant chemotherapy (AC). IMRT was administered 2 weeks after IC, and AC was administered 1 month after IMRT. IC or AC (TPF regimen) comprised docetaxel (60 mg/m2/day, day 1), cisplatin (25 mg/m2/day, days 1-3), and 5-fluorouracil (500 mg/m2/day with a 120-h infusion) administered once every 3 weeks for two cycles. During radiotherapy, involved retropharyngeal lymph nodes and intracavity lesions of the primary tumor were delineated according to the post-IC volume, whereas the remainder of the involved tissues (eg, pterygopalatine fossa) of the primary tumor were delineated according to the pre-IC volume of the primary tumor as shown by MRI. Post-IC volumes of involved neck lymph nodes were used for delineation. The prescribed dose was 66 Gy to tumors above the slices of skull base or below the orapharynx with less than 5 mm retropharyngeal lymph nodes, or 70.4 Gy to tumors in other slices.
Radiation: Reduced Target Delineation and Radiation Doses

The target volumes were delineated according to the treatment protocol defined as follows: the GTV of the primary tumor (GTV-P) included retropharyngeal lymph nodes, considering the common phenomena of integration, and the rest involved lymph nodes that were defined as GTV-N. For the GTV-P, involved retropharyngeal lymph nodes and intracavity lesions were delineated according to the post-IC volume, whereas the remainder of the involved tissues (eg, pterygopalatine fossa) were delineated according to the pre-IC volume of the primary lesion as shown by MRI. Post-IC volumes of involved neck lymph nodes were used for GTV-N delineation.

The prescribed dose was 66 Gy to tumors above the slices of skull base or below the orapharynx with less than 5 mm retropharyngeal lymph nodes, or 70.4 Gy to tumors in other slices.

Other Names:
  • Drug: TPF regimen comprised docetaxel (60 mg/m2/day, day 1), cisplatin (25 mg/m2/day, days 1-3), and 5-fluorouracil (500 mg/m2/day with a 120-h infusion)
