Conditions

Head and Neck Cancer, Squamous Cell Carcinoma

Brief summary

The goal of this clinical trial is to evaluate the safety of applying BNCT with the dose optimization in patients with recurrent head and neck cancer. The main questions it aims to answer are: \- Dose optimized BNCT are conducted safety in these patients. Participants will receive dose optimized BNCT regulated as 12, 15, 18 Gy-Eq of the mucosal dose.

Interventions

RADIATIONAccelerator-based BNCT with borofalan(10B)

Patients will be treated with BNCT regulated as 12, 15, or 18 Gy-Eq of the mucosal maximum dose.

Inclusion criteria

* Signed written informed consent to participate in the clinical trial on their own free will. * Aged over 20 years at the time of consent obtaining. * ECOG performance status (PS) of 0-2. * Histologically confirmed a primary lesion of Head and Neck cancer. * Following condition: 1. Locally Recurrent Head and Neck Squamous Cell Carcinoma after chemo radiotherapy or radiation therapy. 2. Primary Head or Neck Squamous Cell Carcinoma with no indicated of radical radiation therapy for the target lesions. * More than one the target lesions based on RECIST (version 1.1) * Local recurrent lesion localized to unilateral. * Received a fractionated radiation therapy with total doses of ≥40 and ≤80 Gy at around 2 Gy per daily fraction at target lesion sites or an equivalent biologically effective dose. * ≥50 days have passed since the last irradiation date of the prior radiation therapy at target lesion sites to the day of scheduled BNCT * Have an estimated survival of ≥90 days after BNCT. * Estimated able to receive the minimum tumor dose at least 20Gy-Eq. * Screening test values that meet the following criteria. * No abnormal findings of clinical concern in chest X-ray exam.

Design outcomes

Primary

MeasureTime frameDescription
Adverse events (Absence and presence of serious adverse events)Within 90days after the completion of BNCTGrade 3 or higher adverse events as evaluated in CTCAEv5.1 Number of participants with severe adverse events due to an excess of tissue tolerance dose

Secondary

MeasureTime frameDescription
Disease control rate (DCR)Within 90 days after the completion of BNCTDCR is evaluated using RECIST guidelines (version 1.1). DCR is defined as the proportion of subjects with CR, PR, or SD in the target lesions among all eligible subjects.
Objective response rate: ORRWithin 90 days after the completion of BNCTORR within 90 days after the completion of BNCT is evaluated using RECIST guidelines (version 1.1). ORR is defined as the percentage of subjects with CR and PR in the target lesions among all eligible subjects.
Overall survival (OS)Within 2 years after the completion of BNCT or up to the end of this studyOS is defined as the time from the day of the completion of BNCT to death due to all causes. The survey period will be up to the completion of the follow-up survey for all subjects.
Duration of ResponseWithin 2 years after the completion of BNCTThe duration of the response is the time from the confirmed achievement of CR or PR (whichever is recorded first) to the date of initial objectively confirmed recurrence or exacerbation.
Late Adverse EventsFrom 90 days to 2 years after the completion of BNCTThe late Adverse Events are defined as the medical occurrence of the study from the treatment periods to the follow-up periods.
Quality of life (QOL) Score Based on EORTC QLQ C30 and H&N35.Within 2 years after the completion of BNCT or up to the end of this studyQOL score is assessed with EORTC QLQ C30 and H&N35 in the follow-up period. Results are scored as a specified manner by EORTC and changes in scores during the follow up period are evaluated
Quality-Adjusted Life Year (QALY)Within 2 years after the completion of BNCT or up to the end of this studyQOL and life year are multiplied to calculate the QALY. QOL score based on EQ-5D-5L in Japanese version.
Progression-Free Survival (PFS)Within 2 years after the completion of BNCT or up to the end of this studyPFS is defined as the time from the day of the completion of BNCT to the date of initial confirmed PD. The survey period will be up to the completion of the follow-up survey for all subjects.
