Accuracy of modern ultrasonographic techniques in the follow up of patients with superficial bladder carcinoma.

PURPOSE: The present study was carried out to establish the accuracy of modern ultrasonographic techniques in the follow up of patients with superficial bladder carcinoma and to evaluate the patients tolerability of cystoscopy. METHODS: Thirty-three patients with a history of superficial bladder carcinoma under active surveillance were initially examined using transabdominal ultrasound followed in the same day by cystoscopy. RESULTS: Fourteen out of the 33 subjects were found to have bladder carcinoma recurrence on cystoscopy. In 11 cases (78.57%) US accurately diagnosed the bladder carcinoma. Two out of the 3 patients in which, the US examination failed to clearly diagnose bladder carcinoma, were found with a tumor smaller than 3 mm while, in the remaining patient the tumor was located in the inner part of a diverticula. The sensitivity of modern ultrasonographic techniques in the diagnosis of bladder cancer recurrence was 78.5%, the specificity 100%, the positive predictive value 100% and the negative predictive value 86.3%. Regarding the patient tolerability for cystoscopy, 17 patients (51.5%) reported excessive discomfort-low tolerability, 9 (27.2%) moderate discomfort-intermediate tolerability and 7 (21.2%) reported no discomfort-high tolerability. CONCLUSION: The technological evolution has rendered ultrasonography more accurate in the diagnosis of bladder carcinoma and thus it can be incorporated in the follow up schedule of patients with superficial bladder carcinoma.

Mixed germ cell tumor of the testicle with ravdomuosarcomatous component: a case report.

INTRODUCTION: Testicular tumors can be classified as seminomatous and non-seminomatous germ-cell tumor (NSGCT) types. Mixed germ cell tumors contain more than one germ cell component and are much more common than any of the pure histologic forms representing 32%-60% of all germ cell tumors. The composition of these tumors varies. Here we present a rare case of a mixed germ cell tumor composed of seminoma, Yolk sack tumor and teratoma containing a sarcoma component of somatic type malignancy. CASE PRESENTATION: A 32-year-old Caucasian male presented with history of right-sided scrotal swelling since 6 months. Backache was present since 2 months and a history of right epididimitis was also present since 8 months. Alpha-Fetoprotein, beta-HCG and LDH values were found abmormal. USG of the scrotum revealed a large right testis swelling characterized by scarce cystic elements and calcifications. CT scan of the abdomen showed nodular metastasis involving the interaortocaval, precaval, and right para-aortic lymph nodes. The block of enlarged lymph nodes infiltrated the psoas muscle. The patient underwent right-sided high orchidectomy and was given chemotherapy of the BEP regimen. After the 2nd cycle the patient discontinued the chemotherapy and when he came for follow-up after a gap of 3 months, despite the normalisation in tumor markers values, the retroperitoneal mass was relapsed. CT scan of the chest showed multiple lung metastases. CONCLUSION: More than 50% of germ-cell tumors include more than 2 basic germ-cell tumor types, with the exception of spermatocytic seminoma. About 90% of the patients with nonseminomatous tumors can achieve complete cure with aggressive chemotherapy and most of them can be cured. Although prognosis of testicular tumors depends largely on clinical stage, histological type and adhesion to the treatment influence the prognosis as well.
