Survival Following Salvage Surgery after Failed Radiotherapy for Penile Cancer: A SEER-Based Study.

OBJECTIVE: Salvage surgery (SS) for penile cancer (PC) is indicated in the management of local failure following radiation therapy (RT). Reports describing survival outcome are rare. This study aims to assess survival outcome of SS following RT failure in PC. MATERIALS AND METHODS: We used The Surveillance, Epidemiology, and End Results database to identify patients received SS on the penis following RT. Social, demographic and pathological criteria of the patients were gathered. The 1-, 3-, 5-, 10-year survival rates were assessed. RESULTS: Between 1976 and 2013, 17 patients received penile SS following RT. Median age was 65 years (range 47-91 years). The mean follow-up was 51 months (range 3-213 months). Sixteen (94.12%) patients received external beam radiation and 1 (5.88%) received combined external beam radiation with brachytherapy. Tumor histology was squamous cell carcinoma in 16 (94.12%) patients and mucinous adenocar-cinoma in 1 (5.88%). The 1-, 3-, 5- and 10-year overall survival rates were 68.8, 35.7, 35.7 and 10.7%, respectively. The 1-, 3-, 5- and 10-year cancer specific survival rate was 72.7, 48.4, 48.4, and 36.3% respectively. CONCLUSION: Our results demonstrate, the overall survival of PC patients underwent SS was poor with nearly one third of patients dying within the first year and only one third surviving up to 3 years from the SS.

Organ-sparing procedures in GU cancer: part 3-organ-sparing procedures in urothelial cancer of upper tract, bladder and urethra.

PURPOSE: The impact of radical surgery for urothelial carcinoma is significant on patient's quality of life. Organ-sparing surgery (OSS) can provide comparable oncological outcomes and with improved quality of life. In this review, we summarize the indications, techniques and outcomes of OSS for these tumors. METHODS: PubMed® was searched for relevant articles. Keywords used were: for upper tract urothelial carcinoma (UTUC): endoscopic, ureteroscopic/percutaneous management, laser ablation; for urothelial bladder cancer: bladder preservation, trimodal therapy, muscle invasive bladder cancer (MIBC); for urethral cancer: urethra/penile-sparing, urethral carcinoma. RESULTS: Kidney-sparing surgery is an option in patients with low-risk UTUC with better renal function preservation and comparable oncological control to radical nephroureterectomy. In select patients with MIBC, trimodal therapy has better quality of life and comparable oncological control to radical cystectomy. In distal male urethral cancer, penile conserving surgery is feasible and offers acceptable survival outcomes. In female urethral cancer, organ preservation can be achieved, in addition to OSS, through radiation. CONCLUSIONS: In the appropriately selected patient, OSS in upper tract, bladder and urethral carcinoma has comparable oncological outcomes to radical surgery and with the additional benefit of improved quality of life.

Organ-sparing procedures in GU cancer: part 2-organ-sparing procedures in testicular and penile tumors.

PURPOSE: Organ-sparing surgery (OSS) is recommended in selected patients with testicular tumors and penile cancer (PC). The functional and psychological impacts of organ excision for these genital tumors are profound. In this review, we summarize the indications, techniques and outcomes of OSS for these two tumors. METHODS: PubMed® was searched for relevant articles up to December 2018. For Testicular sparing surgery (TSS) search, keywords used were; testicular tumors alone and in combination with "testicular sparing surgery", "partial orchiectomy" and outcomes. For penile conserving surgery (PCS), keywords used were: penile cancer alone and in combination with "penile conserving surgery", "partial penectomy" and outcomes. Because of the low quality of available evidence, a narrative rather that systematic review has been performed. RESULTS: Indications of TSS are tumors ≤ 2 cm in solitary testis or bilateral tumors and no rete testis invasion. Prerequisites include normal testosterone and luteinizing hormone levels and patient compliance with follow-up. Indications for PCS are distal penile lesions with clinical stage ≤ T1. Adequate penile stump (3 cm) is required after surgery to maintain forward urine stream. Frozen section helps to reduce the risk of recurrence. Local recurrence after PCS is not associated with reduced survival and can be managed with another PCS in selected patients. The reported oncological and functional outcomes following TSS and PCS are adequate. CONCLUSIONS: In properly selected patient OSS in testicular and penile tumors has a comparable oncological outcome to total organ excision with added advantages of preserving organ function and psychological well-being.

Regional trends in average years of potential life lost (AYPLL) secondary to prostate cancer deaths among Caucasians and African Americans treated by surgery or radiation.

PURPOSE: To study regional trends in average years of potential life lost (AYPLL) among Caucasians (CA) and African Americans (AA) with prostate cancer (Pca) who received radical prostatectomy or radiation therapy among four different regions in the US as well as across different tumor grades. Years of potential life lost is defined as the difference between a predetermined end-point age and the age at death for a death that occurred prior to that end age, hence the AYPLL is calculated by dividing the total YPLL by the total number of patients died. METHODS: The surveillance epidemiology and end results (SEER) database was used to identify Pca patients who were CA or AA and who have received radical prostatectomy or radiation therapy. Study duration was divided into four decades; 1973-1982 (D1), 1983-1992 (D2), 1993-2002 (D3), 2003-2012 (D4). Examined regions were; North East (NE), North central (NC), South and West. Tumor grade was classified into; well/moderately differentiated (WD/MD) and poorly/undifferentiated (PD/UD) groups. Differences in AYPLL among CA and AA in each of these variables were compared. RESULTS: Overall, compared to CA, AA were diagnosed and died earlier from Pca. AA had higher AYPLL to Pca than CA. In both tumor grade groups, progressive increase in AYPLL among AA compared to CA was noted over the last three decades. In the WD/MD group, except for the South region, the highest recorded difference in AYPLL between AA and CA was in D4. In the PD/UD group, a similar difference in AYPLL between AA and CA was noted in all regions. The difference in AYPLL was higher in the PD/UD group than the WD/MD group. CONCLUSIONS: Racial disparity between AA and CA existed across the examined regions. It is more pronounced in advanced tumor grades. The differences were more significant in the last decade.

Organ-sparing procedures in GU cancer: part 1-organ-sparing procedures in renal and adrenal tumors: a systematic review.

PURPOSE: Organ-sparing surgery (OSS) for the kidney and adrenals has emerged as the need for preservation of function is paramount in patients with poor functional reserve. As reports increasingly showed that oncological outcomes were equivalent to radical excision, elective OSS became a viable alternative in patients with otherwise normal reserve. In this review, we summarize the current knowledge of OSS for adrenal and renal tumors. MATERIALS AND METHODS: PubMed, Web of Science and Cochrane Library Central Search were searched for recently published articles up to December 2017. The following keywords were used; "partial adrenalectomy", "adrenal sparing", "partial nephrectomy", "nephron sparing", "kidney/renal cancer". RESULTS: Partial adrenalectomy became an attractive alternative to total adrenalectomy avoiding adrenal insufficiency. Both minimally invasive surgery and ablative techniques were increasingly reported for adrenal OSS with adequate residual adrenal function and excellent oncological outcome. Radical nephrectomy remained for many years as the gold standard of treatment for organ-confined renal cell carcinoma. As the need to reduce the impact on renal function, more conservative approaches were utilized. Soon, the non-inferiority of nephron-sparing surgery to that of radical excision became evident and elective partial nephrectomy was gaining ground as the standard of care for small renal masses in patients with normal contralateral kidneys. CONCLUSIONS: Herein, we present a comprehensive review of the current status of OSS in renal and adrenal tumors.

Survival outcomes of organ sparing surgery, partial penectomy, and total penectomy in pathological T1/T2 penile cancer: Report from the National Cancer Data Base.

PURPOSE: To describe the survival outcomes of organ sparing surgery (OSS), partial penectomy (PP), and total penectomy (TP) in pathological stage pT1/pT2 penile cancer (PC) as reported in the United States National Cancer Data Base. METHODS: Patients with pT1/pT2 PC, treated with surgery as their primary treatment modality were classified into 3 groups according to the type of surgery into OSS, PP, and TP. Patient and tumor characteristics of the groups were compared using bivariate analysis, and Cox- proportional hazard model was used for survival analysis. RESULTS: A total of 4,238 patients were examined. There were 1,211, 2,360, and 584 patients in the OSS, PP, and TP groups, respectively. In 83 patients, the type of surgery was missing. The 5- and 10-year overall survival rates for OSS, PP, and TP were 88% and 74% vs. 85% and 72% vs. 79% and 63%, respectively (P ≤ 0.001). In addition, in a multivariable model for predictors of patient survival, OSS did not predict poor patient survival (hazard ratio = 0.88, CI: 0.64-1.21). CONCLUSIONS: Our results demonstrate, at national level, OSS in early stage PC provided comparable outcomes in selected patients compared to PP and TP. Also, organ preservation was not associated with any significant reduction in patient survival in early stage PC. Our results help with early stage PC patient informed treatment decisions and anticipated outcomes.

Long-term outcome of genital reconstruction of Middle Eastern women with congenital adrenal hyperplasia.

OBJECTIVES: There is a paucity of data on the long-term outcome of genital reconstruction of female children with congenital adrenal hyperplasia (CAH) as they become adult women. We report on the surgical outcome general condition and marriage status. MATERIALS AND METHODS: We reviewed the medical records of women 20 years or older with CAH who had genital reconstruction. We interviewed married patients utilizing the female sexual function index (FSFI-6) questionnaire and compared them to age-matched controls. RESULTS: We identified 43 women with CAH with a median age of 24.2 ± 3.9 years and a median follow-up of 23.4 ± 4.6 years. Salt wasting and the severity of virilization affected most patients, parents were commonly cousins, children were reared as boys for a protracted period and surgical reconstruction was usually complex. Only five women had married. Compared with single women, married women had significantly more frequent normal menses, emergency hospital admissions and number of repeated reconstructive surgery. There was no significant difference in FSFI score between patients and controls. Four women conceived and three gave birth to one healthy child. There was no significant difference in the number of children between patients and controls. CONCLUSIONS: CAH has a significant impact on adult women in our region. Most of the patients remain single. Few women get married and these are able to lead a nearly normal sexual life and give birth to healthy children.

Outcome of bilateral laparoscopic Fowler-Stephens orchidopexy for bilateral intra-abdominal testes.

INTRODUCTION: To evaluate the outcome of bilateral laparoscopic Fowler-Stephens orchidopexy (BLFSO) for bilateral intra-abdominal testes. MATERIALS AND METHODS: Prospectively, all patients with bilateral intra-abdominal testes between 2006 and 2010 were included in this study. Patients' data were analyzed for age, procedure whether single stage or staged Fowler-Stephens, intraoperative and postoperative complications, and follow up results. RESULTS: BLFSO was performed in a total of 48 testes in 24 boys with a median age of 31.6 months (range 12 to 150). All procedures were performed on an outpatient basis. Of the 24 boys, six were managed with a single stage BLFSO. The remaining 18 patients were managed with staged Fowler-Stephens orchidopexy. Testicular position after laparoscopy was the mid lower scrotum in 43 testes, the remaining five testes retracted to the inguinal canal in three (required inguinal approach for orchidopexy) and to the neck of scrotum in two. Testicular atrophy was encountered in two testes with a follow up of 18 months postoperatively. CONCLUSIONS: Outpatient single stage or staged bilateral laparoscopic Fowler-Stephens orchidopexy were successful in managing boys with bilateral intra-abdominal testes.

Potential years of life lost due to urogenital cancer in the United States: trends from 1972 to 2006 based on data from the SEER database.

PURPOSE: Urogenital cancer is a major health problem in the United States. We assessed potential years of life lost secondary to genitourinary cancer in the United States from 1972 to 2006 using the SEER (Surveillance, Epidemiology and End Results) database. We report trends in potential years of life lost during the same period. MATERIALS AND METHODS: Potential years of life lost were calculated to assess premature mortality trends for ureter, bladder, kidney and renal pelvis, penis, testis and prostate cancers. Calculations were based on SEER cancer mortality data. Potential years of life lost up to and including age 75 years were calculated by and across genders in 5-year increments between 1972 and 2006. RESULTS: A total of 7,733,235 potential years of life were lost in men and women. In each gender the greatest potential loss was for kidney and renal pelvis cancer related mortality. In each gender no improvement in the potential loss due to ureteral and bladder cancer related mortality was observed during 3 decades. In males the greatest decrease in potential years of life lost was for testicular cancer, followed by prostate cancer. CONCLUSIONS: There has been an increasing trend in potential years of life lost related to urogenital cancer during the last 35 years for males and females. This trend is mainly due to an increase in kidney cancer. The continued increase in potential years of life lost due to renal cancer and the lack of a decrease in the loss in those with bladder cancer should alert urologists and health care policy makers to deficient areas that most need to be addressed.

Post-chemotherapy robotic retroperitoneal lymph node dissection (RRPLND) in testicular cancer.

We report here on the safety and feasibility of using robotic surgery for the excision of residual retroperitoneal lymph node metastasis in patients with non-seminomatous germ cell testicular tumors (NSGCT) post-chemotherapy (PC). Two men (age 20 and 21 years, respectively) with residual PC retroperitoneal disease underwent robotic assisted retroperitoneal lymph node dissection (RRPLND). The primary testicular tumor was on the right testicle in one patient and on the left testicle in the other patient. Both patients had a history of testicular NSGCT and bulky retroperitoneal lymph node metastasis and had received chemotherapy. The technique, feasibility, and safety of the RRPLND procedure are reported. RRPLND was safely accomplished in both patients. A right-side approach was performed in one patient; a left-side approach was utilized in the other patient. In both patients, the field of dissection was an ipsilateral template for lymph node dissection, including excision of the residual mass. No intraoperative or postoperative complications were encountered. Pathology showed mature teratomatous elements in both patients. We demonstrate here the safety and feasibility of performing template RRPLND in patients with PC residual masses. Further reports are needed to compare this procedure to its other approaches, namely, standard open and laparoscopic RPLND.

Amelioration of gentamicin nephrotoxicity by green tea extract in uninephrectomized rats as a model of progressive renal failure.

RATIONALE: Gentamicin (GM) is an effective antibiotic against severe infection but has limitations related to nephrotoxicity. This study investigates whether green tea extract (GTE), an antioxidant, could ameliorate the nephrotoxic effect of GM in uninephrectomized rats. OBJECTIVES: The right kidneys of 40 rats were surgically removed and 1 week later the animals were divided into four groups (n = 10). Group 1 served as control, Group 2 as GTE group, Group 3 as GM group, and Group 4 as GM+GTE group. Kidney function, inflammatory cytokine TNF-α, oxidant and antioxidant parameters of renal tissue, as well as histopathological studies were assessed. MAIN FINDINGS: Injecting uninephrectomized rats with GM induced renal dysfunction as shown by significant elevations in serum creatinine and urea. Serum TNF-α and oxidative stress parameters (superoxide anion and lipid peroxides) were also significantly increased. On the contrary, antioxidative parameters [superoxide dismutase (SOD), catalase (CAT), and reduced glutathione (GSH)] were significantly decreased. Histopathological examination of renal tissue illustrated features of degeneration, marked cellular infiltration, tubular dilatation, and varying degrees of necrosis. GTE given to GM rats reduced these nephrotoxicity parameters. Serum creatinine, urea, and TNF-α were almost normalized in the GM+GTE group. The oxidative stress parameters were significantly decreased and the antioxidative parameters were significantly increased. CONCLUSION: GTE ameliorates GM-induced nephrotoxicity and oxidative damage by improving antioxidant defense and tissue integrity. Further human studies are necessary to demonstrate the antioxidant effects of GTE on renal diseases. Nevertheless, green tea (GT) may offer an inexpensive, nontoxic, and effective intervention strategy in subjects with a risk for GM-induced nephrotoxicity.
