Outcomes Of Locally Advanced Cervical Cancer Presenting With Obstructive Uropathy: An Institutional Audit

Background: There is paucity of outcome data of patients with cervical cancer presenting with malignant obstructive uropathy. The present retrospective study describes outcomes of patients with cervical cancer who presented with obstructive uropathy at the time of diagnosis and underwent urinary diversion with percutaneous nephrostomy (PCN) before/during treatment. Methods: Patients who underwent PCN from January 2010 to June 2015 were included. Intent of treatment (radical or palliative) was decided within multidisciplinary team depending on disease stage, Karnofsky performance status (KPS), and degree of renal derangement. Treatment and outcome details were retrieved from electronic records. Time to normalization of creatinine, feasibility of delivering planned treatment, and overall survival (OS) were determined. Impact of various prognostic factors on outcomes was determined using univariate or multivariate analysis. Results: After PCN and double-J stenting, 50% were eligible for (chemo) radiation. All radically treated patients (26/52) received brachytherapy. The median EQD2 to point A was 78 Gy (72-84 Gy). The median OS was 10 (0.5-60) months. Patients who completed chemoradiation had median OS of 31 months. Those receiving radical radiation and palliative radiation had median OS of 11 and 6 months, respectively. On univariate analysis, smaller tumor size (p = 0.03), high KPS (P = 0.04), and radical intent of treatment (P = 0.05) predicted for OS. Conclusion: Patients presenting with obstructive uropathy have median OS less than a year despite urinary diversion. Select cohort with good performance status, small tumor size, and serum creatinine of <= 3 mg/dL may be selected for diversion procedures and potential radical treatment.
