Abstract:

Objective:

Describe   clinical   and   paraclinical 

characteristics and some factors related to lymph node 

metastasis  in  patients  with  thyroid  cancer  who  came 

for   examination   and   treatment   at   Thai   Nguyen 

National   Hospital. 

Subjects    and    methods:

A

retrospective  study  on  107  patients  diagnosed  with 

thyroid  cancer  at  Thainguyen  National  Hospital  from 

January  2024  to  December  2024. 

Results:

Thyroid 

cancer occurs in all ages, with an average age of 46.8 

± 11.5 years old, primarily in women with 94.4%. The 

main  reason  for  admission  to  the  hospital  was  by 

accident  detection  (40.19%),  and  tumour  locations 

were  mainly  in  the  right  lobe  (37.4%).  On  thyroid 

ultrasound,    75.7%    of    patients'    tumours    were 

evaluated  by  TIRADS  5.  Of  107  patients,  lymph  node 

metastasis   was   found   in   34   patients,   of   which 

metastasis  to  the  central  cervical  lymph  nodes  alone 

accounted   for   41.2%.   The   cervical   lymph   node 

metastasis  rate  was  higher  in  patients  with  a  tumour 

size greater than 0.5 cm, and the tumour had invaded 

outside  the  thyroid  gland,  which  increased  the  risk  of 

lymph  node  metastasis  with  statistical  significance
