There was only 1 case of local recurrence, and there were no cases of metastasis. A high ROADS score was correlated with greater operative complexity, such as longer operation and ischemia times and higher estimated blood loss and complication rates. However, renal function and short-term oncologic outcomes were not related to the score. CONCLUSIONS The ROADS scoring system provides a standardized, quantitative, 3-dimensional anatomic classification to guide surgical strategy in renal sinus tumors. © 2020 American Cancer Society.BACKGROUND Imatinib is the standard treatment for patients with gastrointestinal stromal tumors (GISTs), but there is significant variation in imatinib plasma trough concentrations (Cmin ) among patients. The imatinib Cmin distribution at different doses and the correlation of adverse reactions with Cmin in Chinese patients with GIST from a high-volume center were evaluated. METHODS From July 1, 2017 to December 31, 2018, patients who were receiving imatinib treatment for GIST were prospectively enrolled. Steady-state blood samples were obtained from patients who had received same-dose imatinib treatment for ≥1 month with good compliance. Adverse reactions were recorded during regular follow-up, and blood samples were collected 24 ± 2 hours after dosing. Liquid chromatography-tandem mass spectrometry was used to measure drug concentrations. RESULTS In total, 307 patients who received 367 dose levels were investigated. The imatinib Cmin was 1315 ± 716 ng/mL, 2117 ± 597 ng/mL, and 3844 ± 987 ng/mL in patients who were receiving imatinib 400 mg, 600 mg, and 800 mg daily, respectively. The Cmin was significantly correlated with periorbital and limb edema (P less then .001), anemia (P less then .001), and rash (P = .037). Nausea and vomiting, diarrhea, and conjunctival
