Study Description

Brief Summary:

To determine 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 nasopharyngeal carcinoma

Condition or disease	Intervention/treatment	Phase
Nasopharyngeal Carcinoma	Radiation: Reduced Target Delineation and Radiation Doses	Phase 2

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.

Intervention/treatment

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 Name: 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)

Outcome Measures

Primary Outcome Measures :

1. Progression-free survival [ Time Frame: up to 5 years ]
   The time from date of treatment until date of first documented disease progression or death from any cause, assessed up to 5 years.

Secondary Outcome Measures :

1. Local recurrence-free survival [ Time Frame: up to 5 years ]
   The time from date of treatment until date of first documented disease recurrence at a local site, assessed up to 5 years.
2. Regional recurrence-free survival [ Time Frame: up to 5 years ]
   The time from date of treatment until date of first documented disease recurrence at a regional site, assessed up to 5 years.
3. Overall survival [ Time Frame: up to 5 years ]
   The time from date of treatment until date of death due to any cause, assessed up to 5 years.
4. Distant metastasis-free survival [ Time Frame: up to 5 years ]
   The time from date of treatment until date of first documented distant metastasis, assessed up to 5 years.
5. Locoregional failure patterns [ Time Frame: up to 5 years ]
   The failures were categorized as occurring inside or outside the high dose target volume, depending on the location of Vrecur: "in field" if 95% of Vrecur was within the 95% isodose; "marginal" if 20% to 95% of Vrecur was within the 95% isodose, or "outside" if less than 20% of Vrecur was inside the 95% isodose.
6. Number of participants with acute toxicities [ Time Frame: during treatment ]
   Number of participants with acute toxicities occurred during the chemoradiotherapy according to CTCAE4.0
7. Number of participants with late toxicities [ Time Frame: up to 5 years ]
   Number of participants with late toxicities occurred from 3 months after completion of radiotherapy to last follow-up visit according to Radiation Therapy Oncology Group radiation morbidity scoring criteria.
8. Changes of tumor volume [ Time Frame: 2 weeks after completion of induction chemotherapy ]
   Changes of tumor volume before and after induction chemotherapy
9. Relationship between treatment failure and dose received by target [ Time Frame: up to 5 years ]
   Relationship between treatment failure and dose received by target
