About this trial

The aim 1 of this trial is the development of the Circulating tumor cells (CTCs) definition of oral cancer minimal residual disease (MRD), and aim 2 is a prospective trial of oral cancer treatment. If this trial is successful, it is expected that it may be able to provide a standard diagnostic tool (MRD in Oral Cavity Squamous Cell Carcinoma (OCSCC)) and treatment mode (extended adjuvant chemotherapy with low-dose oral chemotherapy). The survival rate of patients will be improved.

Eligibility criteria

This trial accepts healthy volunteers

Treatments tested in this trial

  • low-dose oral chemotherapy

    Procedure/Surgery

Trial outcomes

Primary outcomes

1

Circulating tumor cells (CTCs) testing

participants will undergo CTCs testing after completing concurrent Chemoradiotherapy (CCRT). If CTC-positive (≥5.0 cells/mL), participants will receive low-dose oral chemotherapy for three months, followed by repeat CTC testing. Persistent positivity will warrant continued treatment up to one year after curative surgery, while negativity will lead to treatment discontinuation.

Circulating tumor cells (CTCs) testing

participants will undergo CTCs testing after completing concurrent Chemoradiotherapy (CCRT). If CTC-positive (≥5.0 cells/mL), participants will receive low-dose oral chemotherapy for three months, followed by repeat CTC testing. Persistent positivity will warrant continued treatment up to one year after curative surgery, while negativity will lead to treatment discontinuation.

Circulating tumor cells (CTCs) testing

participants will undergo CTCs testing after completing concurrent Chemoradiotherapy (CCRT). If CTC-positive (≥5.0 cells/mL), participants will receive low-dose oral chemotherapy for three months, followed by repeat CTC testing. Persistent positivity will warrant continued treatment up to one year after curative surgery, while negativity will lead to treatment discontinuation.

Circulating tumor cells (CTCs) testing

participants will undergo CTCs testing after completing concurrent Chemoradiotherapy (CCRT). If CTC-positive (≥5.0 cells/mL), participants will receive low-dose oral chemotherapy for three months, followed by repeat CTC testing. Persistent positivity will warrant continued treatment up to one year after curative surgery, while negativity will lead to treatment discontinuation.
