Total neoadjuvant treatment for anal adenocarcinoma with inguinal lymph node metastasis: A case report

Abstract

Background

Metastasis of anal adenocarcinoma to inguinal lymph nodes is a rare occurrence and published literature on the optimal management strategy for these patients is limited.

Case presentation

We present a case where the use of total neoadjuvant therapy (long course concurrent chemoradiotherapy followed by chemotherapy alone), surgical resection of primary anal disease and selective inguinal lymph nodes is dissection was used to treat a male in his sixties with anal adenocarcinoma with inguinal lymph node metastasis. This was a novel approach in our centre where the management of rectal adenocarcinoma was extrapolated to treat anal adenocarcinoma.

Conclusion

There is no clear guideline for management of anal adenocarcinoma with metastasis to inguinal lymph nodes. This case offers an approach for future patients with similar pathology that appears feasible in the short term 1 year follow up.
