Adrenalectomy for solitary metastasis of Hepatocellular carcinoma post liver transplantation: Case report and literature review

Liver transplantation [LT] is the treatment of choice for localized hepatocellular carcinoma [HCC] associated with cirrhosis. Extra hepatic metastasis is the most common cause of death in these patients. There is very little evidence regarding the natural history and treatment options for patients developing HCC recurrence after LT

Surgical resection offers a unique opportunity for solitary metastasis

We report a 61 year old male with solitary right adrenal metastasis 15 months post LT which was managed with open adrenalectomy. The patient is alive and disease free 24 months after the surgery. The case, histo-pathological findings and literature review is discussed

New and contemporary markers of prognosis in nonmuscle invasive urothelial cancer

Nonmuscle invasive (NMI) urothelial cancer (UC) is associated with varied biological potential. It is characterized by frequent recurrence and progression, which thus worsens the oncological outcome. Nearly three-quarters of NMI UCs recur within 5 years, whereas half can progress during follow-up. Progression is particularly seen in T1 and carcinoma in situ (CIS). Undoubtedly, NMI UC is one of the most expensive cancers to manage. The European Organisation for Research and Treatment of Cancer (EORTC) risk calculator is a commonly used tool for assessing the recurrence and progression potential of a newly diagnosed cancer. The parameters used in the assessment are tumor size and number, pathological stage and grade of the cancer, presence of CIS, and prior recurrence rate. The main advantages of the EORTC tool are its ease of use and the lack of need to run expensive molecular tests. However, reproducibility of pathologic stage and grade is modest, which is a concern to clinicians. Molecular markers have potential for predicting the clinical outcome of NMI UC, given that clinico-pathologic variables are not sufficient for prediction of prognosis in an individual. Significant work has been done in the past 2 decades in understanding the molecular biology of bladder cancer; however, the translational value of this knowledge remains poor. The role for molecular markers in predicting recurrence seems limited because multifocal disease and incomplete treatment are probably more important for recurrence than the molecular features of a resected tumor. Urinary markers have very limited value in prognostication of bladder cancer and are used (mainly as an adjunct to cytology) for detection and surveillance of urothelial cell cancer recurrence. Prediction of progression with molecular markers holds considerable promise. Nevertheless, the contemporary value of molecular markers over clinico-pathologic indexes is limited.

Functional and clinical outcome of ileal [studer] neo-bladder reconstruction: single centre experience from Pakistan

To determine the medium and long-term outcome of orthotopic continent urinary diversion with ileal [Studer] neo-bladder following radical cystectomy. Case series. Department of Surgery, The Aga Khan University Hospital, Karachi, from January 1998 to September 2010. Thirty eight patients underwent radical cystectomy for invasive bladder tumor with ileal neo-bladder [Studer type] reconstruction. Peri-operative and late complications, functional outcome of neo-bladder, urinary continence, metabolic and upper urinary tract status and overall survival were evaluated in all patients. A total of 29 patients [23 males and 6 females] with mean age of 59 +/- 12 years were included for the final analysis. The mean duration of surgery [both radical cystectomy and urinary diversion] was 520 +/- 70 minutes. Perioperative complication rate was 24% [n=7] with surgical site infection in 4 patients, sepsis in 1 patient and 2 had ureteroileal leak. At 6 months follow-up, 22 patients were fully continent while 7 patients had minimal stress / nocturnal incontinence. The continence rate was 93% [n=27] at one year follow-up. The mean capacity of neo-bladder at 6 months was 384 +/- 66 mLs. The late complication rate was 17% [n=5]. Three patients developed anastomotic stricture requiring transurethral incision of neo bladder neck, one formed stone in neo-bladder and one developed incision hernia. All patients had preserved renal functions on follow-up. The survival rate was 80% [n=23] at a median follow-up of 66.4 +/- 36 months. Two patients developed local recurrence and four developed distant metastasis. Studer ileal neo-bladder is a safe and effective option for urinary diversion in select patients with good oncological and functional outcomes comparable to contemporary literature, even in a low volume center

Optimal Management of Lower Polar Calyceal Stone 15 to 20 mm

PURPOSE: To compare the stone clearance rate, efficiency quotient (EQ), and early complications of shock wave lithotripsy (SWL) and percutaneous nephrolithotomy (PCNL) for solitary lower-pole renal stones measuring 15 to 20 mm. MATERIALS AND METHODS: This was a retrospective matched-pair analysis of 142 patients (78 in the SWL and 64 in the PCNL group). Preoperative imaging was done by use of noncontrast computed tomography (CT kidney, ureter, and bladder [KUB]), intravenous urogram, or plain X-ray and ultrasound KUB to assess the largest dimension of the stones. Only patients with radiopaque stones were included. The stone-free rates were assessed with plain X-ray and ultrasound at 4 weeks. Data were analyzed by use of SPSS ver. 19. RESULTS: The patients' demographic profiles (age, body mass index) and the stone sizes were comparable in the two groups. The mean stone size was 17.4+/-2.12 in the PCNL group compared with 17.67+/-2.04 in the SWL group (p=0.45). At 4 weeks, 83% of patients undergoing PCNL were stone-free compared with 51% in the SWL group (p<0.001). The EQ for the PCNL group was 76% compared with 44% for the SWL group (p<0.001). Ancillary procedures were required by 9% of patients in the PCNL group compared with 15% in the SWL group. The complication rate was 19% in both groups. The SWL complications were minor. CONCLUSIONS: Stone clearance from the lower pole of solitary stones sized 15 to 20 mm at the greatest diameter following SWL is poorer. These calculi can be better managed with percutaneous surgery owing to its higher efficacy and acceptably low morbidity.

Sarcomatoid carcinoma of prostate involving the whole lower urinary tract and rectum

Sarcomatoid carcinoma of prostate is an extremely rare but aggressive neoplasm. It is generally associated with a poor prognosis. About 100 cases have so far been reported in the English literature. We report the case of a 64-year-old male with a very rapidly progressive disease that ultimately involved the whole lower urinary tract and rectum. The management of this case along with etio-pathogenesis and literature review is discussed
