Area of Science:

  • Oncology
  • Surgical Pathology

Background:

  • Anal cancer metastasis commonly involves inguinal lymph nodes, impacting prognosis.
  • Inguinal lymph node status is a critical prognostic factor in anal cancer management.
  • Metastasis to superficial inguinal nodes occurs in 15-25% of cases, varying with tumor characteristics.

Observation:

  • A sentinel lymph node biopsy was performed to assess inguinal lymph node status in a female patient with squamous cell carcinoma of the anus.
  • The sentinel node identification and examination were positive for metastases.
  • Postoperative histology confirmed bilateral lymph node metastases.

Findings:

  • Sentinel lymph node biopsy successfully identified inguinal lymph node metastases.
  • Histological examination of the sentinel node revealed the presence of cancer spread.

Implications:

  • Sentinel lymph node examination is a potentially efficient method for staging anal cancer.
  • Accurate inguinal lymph node staging can inform optimal treatment planning and execution.
  • This approach may improve the management of anal cancer by precisely identifying nodal involvement.
