BackgroundDespite its toxicity, cisplatin every 3 weeks (q3w) is the standard potentiation of chemo-radiotherapy for head and neck squamous cell carcinoma. This study aimed to determine whether weekly cisplatin (q1w) could be a safe and effective alternative.Patients and methodsTwo hundred and sixty-two patients with head and neck squamous cell carcinoma, irradiated in our institution with cisplatin (q1w or q3w) between January 2004 and December 2008, were retrospectively included. Overall survival (OS) and progression-free survival (PFS) were evaluated. Survival distributions were estimated by Kaplan–Meier method and compared using the log-rank test. Prognostic effect of chemo-radiotherapy was explored using Cox model.ResultsA total of 165 and 97 patients received q1w and q3w cisplatin, respectively. Median age, stage at diagnosis, alcohol consumption, intensity-modulated radiation therapy use, median weight, and renal failure before radiotherapy were significantly different, showing lower risk in the q3w group. Q3w cisplatin was found to be more toxic in terms of weight loss, renal failure, worse chemotherapy plan completion, and grade 3/4 mucositis and dermatitis, with more patients requiring analgesics, secondary hospitalization, and radiotherapy interruption (≥3 days), and patients affected by long-term toxicities. With a median follow-up of 73 months (95% confidence interval [CI] [68.9–76.2]), OS was found to be significantly better with q3w (5 years OS: 62.3%; 95% CI [51.6–71.3]) than with q1w cisplatin (5 years OS: 52.6%; 95% CI [44.5–60.0]) (log-rank P=0.0146). More number of patients treated according to the q1w schedule experienced a recurrence: 47.3% vs 30.9% (P=0.009). Thus, the PFS for q3w schedule was found to be globally better (5 years PFS: 55.8%; 95% CI [45.0–65.3]) than for q1w schedule (5 years PFS: 43.6%; 95% CI [35.9–51.0]) (log-rank P=0.0161). However, both multivariate analyses, OS and PFS, produce no significant hazard ratio for chemo-radiotherapy modality once adjusted on unbalanced covariates according to the descriptive analysis.ConclusionThough q1w seemed to be safer than q3w according to the descriptive analysis, multivariate analyses failed to conclude about its efficiency. Therefore, we conclude that the q3w schedule should remain the standard and prospective comparisons are needed.
Laser endoscopic surgery is 1 of the conservative surgical ways to manage laryngeal chondroma especially in cases of elderly patients with poor health status. It permits adequate removal of the tumor and still maintains structural and functional integrity and preserves possibilities of subtotal or total salvage surgery.
According to the high morbimortality, it is important to carefully select the right patients for surgery.
Radiation therapy (RT), either alone or in combination with surgery and/or chemotherapy is a keystone of cancers treatment. Early toxicity is common, sometimes leading to discontinuation of treatment. Recent studies stressed the role of the phosphorylated ATM (pATM) protein in RT-toxicity genesis and its ability in predicting individual radiosensitivity (IRS) in fibroblasts. Here we assessed the reliability of the pATM quantification in lymphocytes to predict IRS. A first retrospective study was performed on 150 blood lymphocytes of patients with several cancer types. Patients were divided into 2 groups, according to the grade of experienced toxicity. The global quantity of pATM molecules was assessed by ELISA on lymphocytes to determine the best threshold value. Then, the binary assay was assessed on a validation cohort of 36 patients with head and neck cancers. The quantity of pATM molecules in each sample of the training cohort was found in agreement with the observed Common Terminology Criteria for Adverse Events (CTCAE) grades with an AUC = 0.71 alone and of 0.77 combined to chemotherapy information. In the validation cohort, the same test was conducted with the following performances: sensitivity = 0.84, specificity = 0.54, AUC = 0.70 and 0.72 combined to chemotherapy. This study provides the basis of an easy to perform assay for clinical use.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
