Weekly paclitaxel with concurrent radiotherapy followed by adjuvant chemotherapy in locally advanced nasopharyngeal carcinoma

Purpose

To evaluate the efficacy and toxicity of weekly paclitaxel with concurrent radiotherapy followed by adjuvant chemotherapy (AC) in patients with locally advanced nasopharyngeal carcinoma (NPC).

Methods and materials

Between 2004 and 2007, 54 patients with locally advanced NPC were included in this protocol. Patient characteristics: median age 48; 69% male; 52% World Health Organization (WHO) III; 50% stage III, 50% stage IV. The patients underwent a course of definitive conventional radiotherapy (70 Gy in 7 weeks with 2 Gy/fraction), with concurrent weekly paclitaxel 35 mg/m² from the first to the sixth week of radiation. AC was started 4 weeks after the end of the radiotherapy (RT), paclitaxel 135 mg/m² on day 1 and cisplatin 30 mg/m² on days 1-3 were administered every 4 weeks for two cycles.

Results

Median follow-up was 32 months. Eighty-five percentage of complete response and 15% partial response were achieved at the time of one month after AC. The 3-year actuarial rate of local regional control was 86%; distant metastases-free survival, progression-free survival and overall survival at 3 years were 81%, 69% and 76%, respectively. Forty-nine (91%) patients completed six courses of concurrent chemotherapy with weekly paclitaxel, and 4 (7%) patients delayed at the second cycle of AC. No patient developed severe acute toxicities.

Conclusions

Weekly paclitaxel with concurrent RT followed by AC is a potentially effective and toxicity tolerable method for locally advanced NPC. Further studies are needed to identify the optimal dose of weekly paclitaxel in this strategy.

Induction chemotherapy to weekly paclitaxel concurrent with curative radiotherapy in stage IV (M0) unresectable head and neck squamous cell carcinoma: a dose escalation study

The purpose was to determine the maximum tolerated dose (MTD) of weekly paclitaxel with concurrent, daily irradiation in patients with unresectable head and neck squamous cell carcinoma previously submitted to induction chemotherapy. Patients with stage IV, and unresectable tumor and/or node/s were enrolled. Nine male patients were submitted to a course of paclitaxel 175 mg/m2 day 1 and cisplatin 75 mg/m2 day 2 given every 3 weeks for three courses. Curative radiotherapy (RT) started 3 weeks after the last cycle of chemotherapy with the goal of delivering a total dose of 66-70 Gy. During RT weekly paclitaxel was administered for 6 courses if feasible; paclitaxel was given according to a dose escalation schema in cohorts of three patients. Dose level A, 30 mg/m2; dose level B, 40 mg/m2; dose level C, 50 mg/m2. During weekly paclitaxel the major toxicity was mucositis that required a treatment break in two of three patients in dose level C; mucositis grade 4 required interruption of paclitaxel administration in all these patients. RT can be given in a continuous fashion with weekly paclitaxel after induction chemotherapy. The MTD of weekly paclitaxel was 40 mg/m2.

A phase III study of adjuvant chemotherapy in advanced nasopharyngeal carcinoma patients

To evaluate the role of adjuvant chemotherapy in locally advanced nasopharyngeal carcinoma (NPC) patients, we conducted a randomized Phase III trial comparing radiotherapy (RT) followed by adjuvant chemotherapy to RT alone in patients with advanced NPC.

Between November 1994 and March 1999, 157 patients with Stage IV, M₀ (UICC/AJCC, 1992) advanced NPC disease were randomized to receive standard radiotherapy, as follows: 35–40 fractions, 1.8–2.0 Gy/fraction/day, 5 days/week, to a total dose 70–72 Gy with or without 9 weekly cycles of 24-h infusional chemotherapy (20 mg/m² cisplatin, 2,200 mg/m² 5-fluorouracil, and 120 mg/m² leucovorin) after RT. Of 157 patients enrolled, 154 (77 radiotherapy, 77 combined therapy) were evaluable for survival and toxicity analysis.

With a median follow-up of 49.5 months, the 5-year overall survival and relapse-free survival rates were 60.5% vs. 54.5% (p = 0.5) and 49.5% vs. 54.4% (p = 0.38) for the radiotherapy-alone group and the combined radiotherapy and adjuvant chemotherapy group, respectively. The Cox regression showed that the hazard rates ratio of combined treatment to RT alone was 0.673 (p VALUE = 0.232); the 95% confidence interval was 0.352 and 1.288, respectively. Patients who received combined treatment had a lower systemic relapse rate than radiotherapy-alone patients, according to relapse pattern analysis. The incidence of leukopenia (≥ Grade 3) occurred in 17 out of 819 (2.1%) cycles of weekly chemotherapy. No patient developed moderate to severe mucositis (≥ Grade 3).

We conclude that adjuvant chemotherapy after RT for patients with advanced NPC has no benefit for overall survival or relapse-free survival.

Paclitaxel, 5-fluorouracil and hydroxyurea concurrent with radiation in locally advanced nasopharyngeal carcinoma.

BACKGROUND: Concurrent chemoradiotherapy (CRT) is the standard treatment for locally advanced nasopharyngeal carcinoma (NPC). We conducted a phase II trial using paclitaxel, 5-fluorouracil and hydroxyurea concurrent with radiation (TFHX). PATIENTS AND METHODS: Fifty-nine patients with locally advanced NPC were treated with CRT consisting of 4-day continuous infusions of paclitaxel (20 mg/m(2)/d) and 5-fluorouracil (600 mg/m(2)/d), and oral hydroxyurea 500 mg bid for nine doses, every 3 weeks concurrent with radiotherapy (RT). RT consisted of once daily 200cGy fractions 5 times per week to a total of 7000cGy. RESULTS: Complete response was seen in 86% and 71% of patients at 4 and 12 months after CRT. The median follow-up was 34 months. Twenty-three patients experienced relapse. Sixteen deaths occurred: 13 from progressive disease. Three-year overall survival and progression-free survival were 72% and 54% respectively, with locoregional and distant control rates of 83% and 64% at 3 years respectively. Grade 3 to 4 acute toxicities included oropharyngeal mucositis in 81% of patients treated, dermatitis in 63%, weight loss in 32%, and neutropenia in 22%. Neutropenic fever was seen in 14%. There were no treatment-related deaths from acute toxicity. CONCLUSIONS: TFHX is shown to be feasible in NPC. Non-cross resistant induction chemotherapy should be further studied with this regimen.
