BACKGROUND
Sunitinib is a multiple receptor tyrosine kinase inhibitor (TKI) used for the treatment of renal cell carcinoma (RCC). It increases the median survival considerably with minimum side effects. Alopecia is one of the rare side effects. Metastasis to the ovary is also rare. We report a case of RCC metastasizing to the ovary developing alopecia early on starting sunitinib.
METHODS
A 22-year-old hypothyroid girl underwent right radical nephrectomy for T2N0 RCC. Histopathology was clear cell carcinoma. Six months later, she presented with right iliac fossa pain, imaging revealed metastasis to the ileocolic junction and the ovary, an exploratory laparotomy was carried out and, after debulking, the patient was started on sunitinib. Four weeks after the start of the treatment, she developed alopecia. She was continued with sunitinib therapy till progression.
CONCLUSIONS
The present case shows a rare metastasis to the ovary and early onset of rare adverse event of alopecia on starting sunitinib therapy. In the presence of confounding factors like hypothyroidism and dandruff, establishing this as an adverse reaction of sunitinib is difficult. This case had a unique metastatic spread with involvement of the bowel, ovary and peritoneal carcinomatosis. Use of adjuvant TKI's after resection of primary tumour in nonmetastatic setting may reduce metastatic rates and increase progression-free survival.
