RESUMEN
Objective: To evaluate long-term outcomes in patients homogenously treated with radical cystectomy and ileal conduit for muscle invasive bladder cancer. METHODS: The retrospective study was conducted at the Urology Department of Pakistan Kidney and Liver Institute and Research Centre, Lahore, Pakistan, and comprised data from December 25, 2017, to January 16, 2023, related to patients who underwent radical cystectomy with ileal conduit with or without neo-adjuvant and adjuvant radiation, chemotherapy, or immunotherapy for papillary urothelial carcinom of the bladder. Clinical trajectory, histopathological characteristics and long-term clinical outcomes were noted. Data was analysed using SPSS 20. RESULTS: In our study of 40 patients with muscle invasive bladder cancer, males predominated (32, 80%), with a median age of 57.4 years (IQR: 29-80). Diagnosis was early in 5 (12.5%) patients with varying haematuria durations, while 34 (85%) patients had a smoking history. Comorbidities included hypertension in 17 (42.5%) patients, diabetes in 1 (2.5%) patient, both hypertension and diabetes in 9 (22.5%) patients and a combination of hypertension, diabetes, and ischaemic heart disease in 3 (7.5%) patients. Transurethral resection was performed once in 13 (32.5%) patients and multiple times in 27 (67.5%) patients. Additionally, 5 (12.5%) patients received immunotherapy, 11 (27.5%) patients underwent non-adjuvant radiation, and 14 (35%) patients received non-adjuvant chemotherapy. Papillary urothelial carcinoma was the predominant histological subtype among 37 (92.5%) patients. Patients receiving chemotherapy had significantly better overall survival (p=0.02). No significant differences were noted in recurrence or survival by therapy modality (p>0.05). These findings highlight the significance of early diagnosis, tailored treatments, and comorbidity management in muscle invasive bladder cancer patients. Age stratification revealed significant survival differences across groups (χ²=10.923, df=3, p= 0.012). Analysis by complications did not show age-related survival variations (χ² =3.978, df = 3, p=0.264). Conclusion: Achieving excellent long-term survival in MIBC patients requires a multidisciplinary approach, emphasizing early diagnosis, tailored treatment, and adherence to guidelines and protocols.

Approximately 3% to 4% of all newly diagnosed cancers are kidney tumours, which can develop from either the renal parenchymal tissue or the renal pelvis. Kidney cancer is one of the 13 most prevalent kinds of malignancy worldwide. 85% of all malignant kidney neoplasms are renal cell carcinomas (RCC). We present a rare instance of an RCC that had a thrombus in the ureter and had directly extended into the renal pelvicalyceal system. A thorough diagnostic workup was required because the patient had a number of symptoms, including flank pain, hematuria, and weight loss. Imaging tests identified a renal parenchymal-derived infiltrative tumour with remarkable pelvicalyceal penetration. Neovascularization was found within the tumour as a result of additional search. The discovery of ureteral extension, a peculiar characteristic, raised questions regarding both local and distant metastases. R.E.N.A.L nephrometry score was 11 with high complexity. Multidisciplinary management of the intricate clinical problem was employed. After removing the tumour mass, the ureteral involvement was treated with surgical resection, adjuvant therapy, and CT monitoring over the three-month high-risk follow-up period. With surgery, targeted treatment was employed to stop the cancer from growing. Conclusion: The importance of identifying unusual RCC presentations and employing a comprehensive diagnostic and treatment strategy is emphasised by this study. The complex interaction of ureteral extension, neovascularization, and pelvicalyceal penetration highlights the aggressiveness of advanced RCC. Since we are not aware of any literature documented instances including this combination, there are few studies explaining pelvicalyceal system invasion that defies commonly recognised diagnostic and treatment paradigms for renal cell carcinoma.
