ABSTRACT
Background:
Most nasopharyngeal carcinoma cases are diagnosed at an advanced stage due to their hidden anatomical structure and atypical clinical symptoms and often require chemoradiotherapy. Here, we present a systematic review and pooled analysis to synthesize existing research on the efficacy and adverse effects of weekly versus triweekly cisplatin chemotherapy concomitant with radiotherapy for locally advanced nasopharyngeal carcinoma (LANPC).Methods:
We searched the PubMed, Embase, and Cochrane Library databases from inception to 1 September 2021, for relevant original research articles published in English. The literature search and data extraction were done independently by two investigators. We used random-effects models to provide point estimates [95% confidence interval (CI)] of overall response rate (ORR), overall survival (OS), progression-free survival (PFS), locoregional recurrence-free survival (LRFS), distant metastasis-free survival (DMFS) and the incidence rate of adverse effects (AEs) and with subgroup analysis according to each study type. The primary endpoints were ORR, OS, and PFS; LRFS, DMFS, and grade ≥3 acute AEs were secondary endpoints.Results:
In total, 2,305 patients of eight studies were included in this review. We found that patients who were administered cisplatin weekly or triweekly had no differences in ORR, OS, PFS, DMFS, LRFS, severe mucositis, dermatitis, nausea/vomiting or nephrotoxicity. Patients who were administered weekly cisplatin were at a higher risk of hematological toxicity compared with patients who received the chemotherapy triweekly.Conclusion:
Our findings suggest that both regimens could be recommended as the standard of care for the chemoradiotherapy treatment of LANPC, the perceived benefit of lower toxicity with weekly cisplatin could not be established.
