Prevalence of urinary tract cancer in the Spanish cohort of the IDENTIFY study.

INTRODUCTION: Malignant tumors of the urinary tract are associated with high morbidity and mortality, and their prevalence can vary worldwide. Recently, the IDENTIFY study has published results on the prevalence of urinary tract cancer at a global level. This study evaluates the prevalence of cancer within the Spanish cohort of the IDENTIFY study to determine whether the published results can be extrapolated to our population. PATIENTS AND METHODS: An analysis of the data from the Spanish cohort of patients in the IDENTIFY study was performed. This is a prospective cohort of patients referred to secondary care with suspected cancer, predominantly due to hematuria. Patients were recruited between December 2017 and December 2018. RESULTS: A total of 706 patients from 9 Spanish centers were analyzed. Of these, 277 (39.2%) were diagnosed with cancer: 259 (36.7%) bladder cancer, 10 (1.4%) upper tract urothelial carcinoma, 9 (1.2%) renal cancer and 5 (0.7%) prostate cancer. Increasing age (OR 1.05 (95% CI 1.03-1.06; P < 0.001)), visible hematuria (VH) OR 2.19 (95% CI 1.13-4.24; P = 0.02)) and smoking (ex-smokers: OR 2.11(95% CI 1.30-3.40; P = 0.002); smokers: OR 2.36 (95% CI 1.40-3.95; P = 0.001)) were associated with higher probability of bladder cancer. CONCLUSION: This study highlights the risk of bladder cancer in patients with VH and smoking habits. Bladder cancer presented the highest prevalence; higher than the prevalence reported in previous series and presented in the IDENTIFY study. Future work should evaluate other associated factors that allow us to create cancer prediction models to improve the detection of cancer in our patients.

[Scrotal liposarcoma]. / Liposarcoma escrotal.

OBJECTIVE: To describe an additional case of scrotal liposarcoma and its treatment, which was distinct from conventional treatment. METHODS: The literature on paratesticular masses is reviewed with special reference to the liposarcomas. An additional case of liposarcoma is described which was treated by tumor excision without involvement of the testis. The diagnosis, classification and treatment of this condition are discussed. RESULTS: Liposarcoma is a very uncommon tumor and its diagnosis is based on the anatomopathological findings. Treatment is by orchidectomy with high ligation of the spermatic cord. However, the case described herein was treated only by resection of the tumor. Radiotherapy may be indicated in some cases. Chemotherapy does not appear to be useful in this type of tumor. CONCLUSION: In some cases of scrotal liposarcoma, the tumor can be resected without performing orchidectomy.

[Retroperitoneal liposarcoma in a patient with renal transplantation]. / Liposarcoma retroperitoneal en un paciente trasplantado renal.

A case of retroperitoneal sarcoma in a kidney transplanted patient is presented. We describe the presentation pattern and the aggressive outcome despite the surgical removal of 5.900 gr. retroperitoneal tumor, included native kidney. The patient died due multiple metastasis six months later. An interesting iconography shows the great volume of the tumor.

[Pelvic lipomatosis: contribution of a new case to the literature]. / Lipomatosis pelviana: aportación de un nuevo caso a la literatura.

OBJECTIVE: To describe an additional case of pelvic lipomatosis, a rare condition that can be encountered by the urologist. METHODS/RESULTS: A 66-year-old patient consulted for irritative voiding syndrome and fever. Patient evaluation by IVP and CT demonstrated pelvic lipomatosis. CONCLUSIONS: Pelvic lipomatosis is a disease with variable clinical and radiological features. Careful follow-up is warranted for prevention and treatment of possible complications.

[Renal carcinoma with vena cava invasion. A new case]. / Carcinoma renal con invasión de vena cava. Un nuevo caso.

It is well known that the renal carcinoma can progress to the renal vein and cava. The MRI is the most accurate study in order to assay the extension of the thrombus. The surgical management is based on the extension and location of the thrombus. New immunologic-based treatment is now being tested. We describe our experience with surgical management of the one case of renal carcinoma with cava vein thrombus. No evidence of progression is noted after 18 month follow up.
