Rectal Metastasis of Renal Cell Carcinoma

Abstract

To the Editor We read with great pleasure the article titled 'Rectal Metastasis of Renal Cell Carcinoma'. We agree with the authors that metastasis of renal cell carcinoma to the large intestine is indeed rare (1). The authors have mentioned that delayed recurrence 21 years after surgery was the longest delay; however, there are reports describing recurrence occurring as late as 30 years after nephrectomy (2, 3).The American Urological Association (AUA) and National Comprehensive Cancer Network (NCCN) have specific guidelines for surveillance protocol for renal cell carcinoma following resection depending on the stage at the diagnosis (4, 5). It would enhance the reader's knowledge had there been mention of the patient's stage at the diagnosis, with appropriate recommendation on surveillance.

Letter to the editor: Delayed Metastasis of Renal Cell Carcinoma

“…An independent study also stated that risk factors for late recurrence depend on the size of the tumor at diagnosis, stage at the diagnosis, and histopathology ( 4 ). For this reason, the American Urological Association and National Comprehensive Cancer Network (NCCN) have laid down specific surveillance protocols as mentioned in our previous correspondence ( 5 ).…”
