Summary

Upper urinary tract urothelial carcinoma (UTUC) represents a rare yet aggressive malignancy associated with a dismal prognosis. At the point of diagnosis, nearly half of the patients already have invasive disease, and over 70% present with high-grade UTUC. Currently, radical nephroureterectomy (RNU) remains the gold standard of care for high-risk UTUC. Previous investigations have demonstrated that, in contrast to RNU alone, chemotherapy can effectively reduce the disease recurrence rate and mortality. Moreover, it may confer benefits to patients' overall survival (OS) without impeding the implementation of subsequent definitive surgical treatment. However, the majority of these studies are predominantly retrospective analyses. Although they can, to some degree, reflect the clinical value of neoadjuvant chemotherapy, due to inherent limitations in study design and other confounding factors, there is still a paucity of prospective research evidence for further validation. Considering that RNU can cause a decline in renal function in patients, and in light of prospective trial outcomes, preoperative neoadjuvant chemotherapy (NAC) has emerged as a preferred treatment option for chemotherapy-eligible UTUC patients.

Conditions

• UTUC
• NAC

Interventions

Type	Name	Description
DRUG	Gemcitabine, Cisplatin	Gemcitabine (1000mg/m²) and cisplatin (70mg/m²). Gemcitabine is used on the 1st and 8th days of a 21 - day cycle, and cisplatin is used on the 2nd day of the cycle. A total of 3 - 4 cycles are carried out.A dose reduction to 60% of the original dose (adjusted to 0.6 times the initial dose) will be implemented if deemed clinically necessary, contingent upon meeting either of the following criteria: 1) occurrence of grade 3 or higher treatment-related adverse events as per CTCAE v5.0 guidelines, or 2) evidence of renal impairment manifested by a ≥40% decline in glomerular filtration rate (GFR) from baseline measurements.
