[Squamous cell carcinoma of the renal pelvis with elevation of G-CSF in the serum: a case report].

A 67-year-old man was admitted with left renal pelvic tumor. He had a leukocytosis of 26,500/mm3 (neutrophils: 81.7%) in the peripheral blood, but with no obvious focus of infection. Moreover, the serum granulocyte-colony stimulating factor (G-CSF) and squamous cell carcinoma antigen (SCC) were elevated. Abdominal enhanced computed tomography (CT) and left retrograde pyelography showed left renal pelvic cancer T4N0M0. He received neoadjuvant chemotherapy (M-VAC: cisplatin + methotrexate + vinblastin + doxorubicin, TN: paclitaxel + nedaplatin). After neoadjuvant chemotherapy, left nephroureterectomy was performed because of normalization of the serum SCC and G-CSF. Histological examination revealed squamous cell carcinoma of the renal pelvis. He is alive with no evidence of disease for 4 years.
