简要总结
Squamous cell carcinomas of the upper aero-digestive tract (SCC-UADT) represent the seventh cause of cancer and affect approximately 600,000 patients per year worldwide. The majority of UADT cancers are diagnosed at an advanced stage (70.3% at stage III and IV) and less than 60% of these patients are free of the disease at 3 years, despite aggressive multimodal local treatment by surgery and /or radiochemotherapy. The average progression-free survival (PFS) at 2 years varies between 45 and 60% depending on the studies. Tumor recurrence is most often incurable. To our knowledge, no study has demonstrated the benefit of early evaluation of the rate of decrease in ctDNA at 1 month after the end of radiotherapy alone or associated with concomitant treatment, as a predictive factor of PFS in UADT squamous cell carcinomas regardless of their HPV status. The main objective of this study is to evaluate the value of measuring the quantity of circulating tumor DNA (ctDNA) at 1 month post-treatment as a predictive factor for PFS at 24 months.
详细描述
This is a prospective, multicenter cohort study carried out on a total of 188 patients suffering from non-metastatic stage III and IV SCC-UADT (oral cavity, larynx, oropharynx, hypopharynx, maxillary sinus), naïve to any treatment during a consultation or day hospitalization during the radiotherapy consultation.
The objective of the study is to evaluate the value of measuring the quantity of circulating tumor DNA (ctDNA) at 1 month post-treatment as a predictive factor for PFS at 24 months. This objective will be achieved by quantitatively measuring the number of copies of methylated ctDNA of genes of interest per mL of plasma; This measurement of ctDNA will be evaluated by the rate of decrease in ctDNA between the centering scanner sample and 1 month post-treatment. Two groups will be then considered: patients with a reduction ≥ 85% and those with a reduction < 85%.
In addition, the interest of measuring the quantity of ctDNA at 1 month post-treatment as a predictive factor of overall survival (OS) and specific survival (SS) at 24 months, the kinetics of the evolution of the quantities of ctDNA during the treatment and during follow-up up to 24 months and the evolution of ctDNA quantities during treatment and follow-up as a predictive factor for PFS and OS at 24 months will also be evaluated during this study. . The analyzes will be carried out in subgroups of populations according to their p16 status (HPV viral protein) and according to the presence or absence of concomitant treatment (Cisplatin or Cetuximab).

结局指标
主要结局
To evaluate the value of measuring the quantity of circulating tumor DNA (tcDNA) at 1 month post-treatment as a predictive factor for progression-free survival at 24 months.
时间窗: At 1 month post-treatment
ctDNA will be measured quantitatively as the number of copies of methylated ctDNA of the genes of interest per mL of plasma. The ctDNA measurement will be evaluated by the rate of decrease in ctDNA between the centering scanner sample and 1 month post-treatment. Two groups will then be considered: patients with a reduction ≥ 85% and those with a reduction \< 85%. Progression-free survival is defined by the time elapsed between the date of end of treatment (radiotherapy associated or not with concomitant treatment) and the onset of disease progression or death from all causes.
次要结局
- Compare the clinico-pathological characteristics according to the 2 defined groups: patients with a ≥ 85% decrease in ctDNA between the centration scanner sample and the sample at 1 month post-treatment and those with a decrease <85%.(1 month.)
- Study the kinetics of the evolution of ctDNA quantities during treatment and during follow-up up to 24 months.(During treatment and follow-up up to 24 months.)
- Evaluate the evolution of ctDNA quantities during treatment and follow-up as a predictive factor for progression-free survival and overall survival at 24 months.(At 24 months.)
- Evaluate the discriminatory capacity of ctDNA at 1 month post-treatment to predict response to treatment at 24 months.(At 1 month post-treatment)
- Evaluate the value of measuring the quantity of ctDNA at 1 month post-treatment as a predictive factor for overall survival and specific survival at 24 months.(At 1 month post-treatment)
- Analyze the populations into subgroups according to their p16 status (HPV viral protein) and according to the presence or absence of concomitant treatment (Cisplatin or Cetuximab).(at 24 months post-treatment.)
