IMRT combined with S-1 concurrent chemoradiotherapy in locally advanced nasopharyngeal carcinoma: a prospective phase II study.
Purpose The current standard treatment for locally advanced nasopharyngeal carcinoma (LANPC) is intensity-modulated radiation therapy (IMRT) plus cisplatin concurrent chemoradiotherapy (CCRT). However, this regimen has well-known hematological and gastrointestinal toxicities. Many studies have reported that S-1 was effective in the treatment of multiple solid cancers with mild toxicities. However, knowledge regarding IMRT plus S-1 CCRT in LANPC is lacking. Therefore, we conducted this prospective phase II trial to evaluate the efficacy and safety of this regimen in LANPC. Patients and Methods Eligible patients with histologically confirmed LANPC were enrolled in this study. IMRT was given in 30-32 fractions five times per week. Concurrently, S-1 was administrated twice per day orally based on the body surface area (BSA < 1.25 m Topics: Adolescent; Adult; Aged; Antineoplastic Combined Chemotherapy Protocols; Chemoradiotherapy; Cisplatin; Drug Combinations; Female; Follow-Up Studies; Humans; Male; Middle Aged; Nasopharyngeal Neoplasms; Organoplatinum Compounds; Oxonic Acid; Paclitaxel; Prognosis; Prospective Studies; Radiotherapy, Intensity-Modulated; Survival Rate; Tegafur; Young Adult | 2019 |

Safety and Feasibility of Low-Dose Apatinib Combined with S-1 as the Second-Line Therapy or Beyond in Chinese Patients with Pulmonary and Hepatic Metastasis of Nasopharyngeal Carcinoma.
The purpose of this study was to analyze the safety and feasibility of low-dose apatinib combined with S-1 as a second-line therapy or beyond in Chinese patients with pulmonary and/or hepatic metastases of nasopharyngeal carcinoma (NPC).. Forty-one Chinese NPC patients with pulmonary and hepatic metastases were treated with low-dose apatinib plus S-1. The S-1 dose was determined according to each patient's body surface area (BSA): 40 mg twice a day for BSA <1.25 m. Treatment efficacy was evaluated in all 41 patients after four courses of chemotherapy. The objective response rate was 34.1%, and the disease control rate was 80.4%. The median progression-free survival was 9.7 months (95% confidence interval, 6.2-13.8 months), and the median overall survival was 22.1 months (95% confidence interval, 15.1-28.9 months). The 2-year survival rate was 41.5%. The most common toxicities included loss of appetite in 39.0% of patients, dyslipidemia in 34.1%, hypertension in 31.7%, myelosuppression in 24.4%, fatigue in 21.9%, and hand-foot syndrome in 17.1%. Seven patients received dose adjustment of apatinib due to side effects.. In patients with pulmonary and/or hepatic metastases of NPC, low-dose apatinib plus S-1 yielded an excellent survival benefit, and the toxicities were mild and tolerable.

Maintenance chemotherapy using S-1 following definitive chemoradiotherapy in patients with N3 nasopharyngeal carcinoma.
Patients with N3 stage nasopharyngeal carcinoma (NPC) are at high risk for treatment failure. This study aims to assess the efficacy of maintenance chemotherapy (MC) using S-1 (MC-S1), a novel oral fluoropyrimidine agent, following definitive chemoradiotherapy (CRT) using intensity-modulated radiotherapy (IMRT) in patients with N3 nasopharyngeal carcinoma (N3-NPC).. A retrospective review was conducted for all N3-NPC treated with CRT with MC (CRT-MC) or without MC (CRT-non-MC) during 2014-2016. Toxicities with MC were recorded. Overall survival (OS), locoregional failure-free survival (LFFS) and distant metastasis free survival (DMFS) were compared between CRT-MC vs. CRT-non-MC cohorts.. A total of 130 N3 patients were identified, of whom 21 (16.2%) were treated with CRT-MC, and 109 (83.8%) with CRT-non-MC. Patient characteristics did not significantly differ between the CRT-MC and CRT-non-MC groups, with the exception of the number of cycles of neoadjuvant chemotherapy. Following IMRT 69 patients achieved a complete response (CR) (CRT-MC: 10; CRT-non-MC: 59), 61 had a partial response (PR) (11 vs. 50), and none maintained stable disease (SD) or developed progression of disease (PD). After a median follow-up of 41 months for surviving patients, a significant differences in OS (76.3% vs. 95.2%, p = 0.046) and DMFS (70.3% vs. 90.5%, p = 0.043) but not LFFS (84.9% vs. 100%, p = 0.091) at 3 years were observed between the CRT-non-MC and CRT-MC groups. Skin hyperpigmentation, leucopenia, fatigue, neutropenia, anorexia and nausea were the common but not severe (grade 1-2) toxicities of MC.. Using MC-S1 in N3-NPC patients following IMRT achieved superior survival to the CRT-non-MC patients. The toxicities of MC-S1 were mild and tolerable. Further clinical trials are required to evaluate the efficacy of MC-S1 in N3-NPC patients.

Safety and efficacy of S-1 chemotherapy in recurrent and metastatic nasopharyngeal carcinoma patients after failure of platinum-based chemotherapy: multi-institutional retrospective analysis.
This retrospective study evaluates the efficacy and safety of S-1 chemotherapy for recurrent and metastatic nasopharyngeal carcinoma patients after failure of platinum-based chemotherapy.. Thirty-nine patients with recurrent and metastatic nasopharyngeal carcinoma who failed previous platinum-based chemotherapy received oral S-1 chemotherapy (twice daily from day 1 to 14) every 3 weeks. The dose of S-1 was determined according to the body surface area (BSA): 40 mg twice a day for BSA <1.25 m(2); 50 mg twice a day for 1.25 m(2) ≤BSA<1.5 m(2); and 60 mg twice a day for BSA ≥1.5 m(2).. Treatment was well tolerated. Most adverse events were mild. Grade 3 hematological toxicity occurred in 7.7%. There was one complete response (2.6%) and 12 partial responses (30.7%), giving an overall response rate of 33.3% (95% CI [confidence interval], 21.7-50.8). Median time-to-progression was 5.6 months, and median survival was 13.9 months. One- and 2-year survival rates were 60% and 26%, respectively.. S-1 monotherapy is considered a safe and effective treatment option for recurrent and metastatic nasopharyngeal carcinoma patients after failure of platinum-based chemotherapy.
