Weekly Low-Dose Versus Three-Weekly High-Dose Cisplatin for Concurrent Chemoradiation in Locoregionally Advanced Non-Nasopharyngeal Head and Neck Cancer: A Systematic Review and Meta-Analysis of Aggregate Data.

ABSTRACT: BACKGROUND:Three-weekly high-dose cisplatin (100 mg/m2) is considered the standard systemic regimen given concurrently with postoperative or definitive radiotherapy in locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN). However, due to unsatisfactory patient tolerance, various weekly low-dose schedules have been increasingly used in clinical practice. The aim of this meta-analysis was to compare the efficacy, safety, and compliance between these two approaches. MATERIALS AND METHODS:We systematically searched literature for prospective trials of patients with LA-SCCHN who received postoperative or definitive conventionally fractionated concurrent chemoradiation. Radiation doses were usually 60-66 gray (Gy) in the postoperative setting and 66-70 Gy in the definitive setting. Standard, three-weekly high-dose cisplatin (100 mg/m2, 3 doses) was compared with the weekly low-dose protocol (?50 mg/m2, ?6 doses). The primary endpoint was overall survival. Secondary outcomes comprised response rate, acute and late adverse events, and treatment compliance. RESULTS:Fifty-two studies with 4,209 patients were included in two separate meta-analyses according to the two clinical settings. There was no difference in treatment efficacy as measured by overall survival or response rate between the chemoradiation settings with low-dose weekly and high-dose three-weekly cisplatin regimens. In the definitive treatment setting, the weekly regimen was more compliant and significantly less toxic with respect to severe (grade 3-4) myelosuppression (leukopenia p?=?.0083; neutropenia p?=?.0024), severe nausea and/or vomiting (p?

Project description:BACKGROUND:Promising efficacy and manageable toxicity of docetaxel-based concurrent chemoradiotherapy (CCRT) were reported in head and neck cancer. In addition, the effect of CCRT in combination with cisplatin and/or 5-fluorouracil on both locoregionally advanced and metastatic/recurrent nasopharyngeal carcinoma (NPC) was verified. However, CCRT with docetaxel for locoregionally advanced NPC are not well studied. This study aimed to compare effectiveness and toxicities of CCRT with weekly docetaxel versus tri-weekly cisplatin for locoregionally advanced NPC. METHODS:Clinical data of patients with locoregionally advanced NPC newly diagnosed between January 2010 and December 2014 receiving CCRT with either weekly docetaxel (15 mg/m2) or tri-weekly cisplatin (80-100 mg/m2) were reviewed. Propensity score matching at a 1:1 ratio was performed to balance baseline characteristics. Adverse events and survival were compared between the two groups. RESULTS:A total of 962 patients were included as the whole cohort, and 448 patients were matched and were regarded as the matched cohort. The median follow-up duration was 48 months for the whole cohort. The 3-year nodal recurrence-free survival rate was significantly increased for patients treated with docetaxel in both the whole (hazard ratio [HR] = 0.37, 95% confidence interval [CI] 0.19-0.72, P = 0.030) and matched cohorts (HR = 0.33, 95% CI 0.14-0.79, P = 0.023). However, no significant differences were observed in overall survival, local recurrence-free survival, and distant metastasis-free survival between the two groups in both cohorts. Significantly higher rates of grade 3 radiodermatitis (6.7% vs. 1.8%, P = 0.001), mucositis (74.5% vs. 37.9%, P < 0.001), and leucopenia (2.2% vs. 11.6%, P < 0.001) were observed in the docetaxel group, but any grade of renal injury (1.8% vs. 15.1%, P < 0.001), vomiting (18.8% vs. 88.3%, P < 0.001), and ALT elevation (19.2% vs. 31.3%, P = 0.027) were more common in the cisplatin group. CONCLUSIONS:CCRT with weekly low-dose docetaxel is an effective and tolerable therapeutic regimen for locally advanced NPC. It provides a survival benefit mainly by improving the control of regional lymph node metastases, especially for patients with low pretreatment EBV DNA levels.

Project description:BackgroundThe objective of this study was to evaluate the prognostic value of the cumulative cisplatin dose (CCD) for long-term survival outcomes after concurrent chemoradiotherapy (CCRT) in locoregionally advanced nasopharyngeal carcinoma (NPC).MethodsPatients were included in an open-label phase III multicenter randomized controlled trial performed at seven institutions in China, and the 298 patients receiving CCRT only were assessed. Patient survival between different CCD groups were compared.ResultsMedian CCD for the 298 patients was 240 mg/m2 (range, 40-320 mg/m2); 113 (37.9%) patients received a CCD of <240 (≤200) mg/m2, and 185 (62.1%) received a CCD of ≥240 mg/m2. For CCD of ≥240 mg/m2 vs. <240 mg/m2, the estimated 5-year overall survival, disease-free survival, locoregional relapse-free survival, and distant metastasis-free survival rates were 83.2% vs. 76.2% (p = .403), 73.5% vs. 67.8% (p = .461), 90.4% vs. 86.8% (p = .551), and 82.6% vs. 79.7% (p = .632), respectively. Multivariate analysis demonstrated that CCD (240 mg/m2) was not an independent prognostic factor in either the entire cohort or stage III/IV subgroup.ConclusionA CCD of ≥240 mg/m2 was not an independent prognostic factor in patients with locoregionally advanced NPC at high risk of distant metastasis, and 200 mg/m2 cisplatin may be adequate to achieve a survival benefit.Implications for practiceThe current standard treatment for locoregionally advanced nasopharyngeal carcinoma (NPC) is cisplatin-based concurrent chemoradiotherapy (CCRT), and the cisplatin is delivered every 3 weeks (100 mg/m2) for three cycles. However, the prognostic value of cumulative cisplatin dose (CCD) delivered during CCRT is controversial. The present study investigated the prognostic value of CCD and demonstrated that a CCD of 200 mg/m2 during CCRT is adequate to achieve satisfactory survival outcomes for patients with locoregionally advanced NPC. This finding is of great importance to clinicians because it could allow patients to avoid excessive treatment and toxicities.
