Association between multidisciplinary team care and the completion of treatment for oral squamous cell carcinoma: A cohort population-based study.

Abstract

This study investigates the relationship between multidisciplinary team care (MDTC) and patient completion of their treatment regimen for oral squamous cell carcinoma (OSCC). We conducted a retrospective cohort study in patients diagnosed with OSCC in Taiwan from 1 January 2016 to 30 June 2018 using a linked cancer registry database. Of the 969 OSCC MDTC patients in the study cohort, 6.3% reported incomplete treatment, with 1.3% interrupting ongoing treatment and 5.0% terminating definitive treatment. Patients who had advanced-stage disease, experienced primary cancer recurrence or a secondary cancer, or were treated with surgery combined with chemotherapy, radiotherapy or chemoradiotherapy were more likely to terminate treatment before completion. The major reasons for interruption of ongoing treatment included 'patient or their family considered the patient to be in poor physical condition' and 'difficulty enduring physical discomfort caused by treatment'. The major reason for termination of definitive treatment was 'patient or their families or friends experienced negative treatment effects and worried about the side-effects of treatment'. Advanced-stage cancer, recurrence or secondary cancer, and surgery combined with chemotherapy, radiotherapy or chemoradiotherapy negatively affected treatment completion. MDTC allows for shared decision-making to determine the optimal treatment.
