Purpose
Outcome analysis of urachal cancer (UraC) is limited due to the scarcity of cases and different staging methods compared to urothelial bladder cancer (UroBC). We attempted to assess survival outcomes of UraC and compare to UroBC after stage-matched analyses.
Materials and Methods
Total 203 UraC patients from a multicenter database and 373 UroBC patients in single institution from 2000 to 2018 were enrolled (median follow-up, 32 months). Sheldon stage conversion to corresponding TNM staging for UraC was conducted for head-to-head comparison to UroBC. Perioperative clinical variables and pathological results were recorded. Stage-matched analyses for survival by stage were conducted.
Results
UraC patients were younger (mean age, 54 vs. 67 years; p < 0.001), with 163 patients (80.3%) receiving partial cystectomy and 23 patients (11.3%) radical cystectomy. UraC was more likely to harbor ≥ pT3a tumors (78.8% vs. 41.8%). While 5-year recurrence-free survival, cancer-specific survival (CSS) and overall survival were comparable between two groups (63.4%, 67%, and 62.1% in UraC and 61.5%, 75.9%, and 67.8% in UroBC, respectively), generally favorable prognosis for UraC in lower stages (pT1-2) but unfavorable outcomes in higher stages (pT4) compared to UroBC was observed, although only 5-year CSS in ≥ pT4 showed statistical significance (p=0.028). Body mass index (hazard ratio [HR], 0.929), diabetes mellitus (HR, 1.921), pathologic T category (HR, 3.846), and lymphovascular invasion (HR, 1.993) were predictors of CSS for all patients.
Conclusion
Despite differing histology, UraC has comparable prognosis to UroBC with relatively favorable outcome in low stages but worse prognosis in higher stages. The presented system may be useful for future grading and risk stratification of UraC.

Decision Based on Narrow Band Imaging Cystoscopy without a Referential Normal Standard Rather Increases Unnecessary Biopsy in Detection of Recurrent Bladder Urothelial Carcinoma Early after Intravesical Instillation
Phil Hyun Song, Seok Cho, Young Hwii Ko
Cancer Res Treat. 2016;48(1):273-280.   Published online March 2, 2015
DOI: https://doi.org/10.4143/crt.2014.190
AbstractAbstract PDFPubReaderePub
Purpose
The purpose of this study was to calculate the operating characteristics of narrowband imaging (NBI) cystoscopy versus traditional white light cystoscopy (WLC) in common clinical scenarios involving suspicion of bladder urothelial carcinoma (UC). Materials and Methods Sixty-three consecutive patients initially underwent WLC and then NBI in a single session for evaluation of microscopic hematuria (group I, n=20), gross hematuria (group II, n=19), and follow-up for prior UC (group III, n=24), by an experienced urologist. All lesions that were abnormal in contrast with adjacent normal mucosa were diagnosed as positive and biopsied.
Results
Sixty-six biopsies from 47 patients were performed. Pathologic examination showed 17 cases of UC from 21 sites. While the overall sensitivity of NBI was similar to that of WLC (100% vs. 94.1%), the specificity of NBI was significantly lower than that of WLC (50% vs. 86.9%, p < 0.001), particularly in group III (38.9% vs. 88.9%, p=0.004). Based on identification by NBI only, 23 additional biopsies from 18 cases were performed for identification of one patient with UC, who belonged to group III. In this group, to identify this specific patient, 15 additional biopsies were performed from 10 patients. All seven cases with positive findings from NBI within 2 months after the last intravesical therapy were histologically proven as negative. Conclusion In evaluation for recurrence early after intravesical instillation, the decision based on NBI increased unnecessary biopsy in the absence of an established standard for judging NBI.

Biopsy Related Prostate Status Does Not Affect on the Clinicopathological Outcome of Robotic Assisted Laparoscopic Radical Prostatectomy
Hoon Choi, Young Hwii Ko, Sung Gu Kang, Seok Ho Kang, Hong Seok Park, Jun Cheon, Vipul R. Patel
Cancer Res Treat. 2009;41(4):205-210.   Published online December 31, 2009
DOI: https://doi.org/10.4143/crt.2009.41.4.205
AbstractAbstract PDFPubReaderePub
Purpose

To determine whether the biopsy core number and time interval between prostate biopsy and radical prostatectomy affect the operative and oncologic outcome of robot assisted laparoscopic radical prostatectomy (RALP).

Materials and Methods

From January 2008 to April 2009, a single surgeon performed 72 RALPs after an initial learning period of 30 cases. The relationship between time from biopsy to prostatectomy and biopsy core number with operative time and estimated blood loss (EBL) were initially evaluated with a linear regression model. These patients were classified into groups according to whether the interval from biopsy to RALP was within four weeks or not, and whether there were less than or greater than 10 core specimens removed.

Results

RALP was performed in 34 patients within four weeks of biopsy, and in 38 patients more than 4 weeks after biopsy. According to the number of core specimens removed, less than 10 cores were performed in 10 patients, and more than 10 cores were performed in 62 patients. Using an interval of 4 weeks as the cutoff point, early surgery was associated with longer operating time (232.6 vs 208.8 min) and increased estimated blood loss (305.1 vs 276.9 mL). For cases with more than 10 biopsy cores, there was a slight increase in operative time (229.2 vs 210.3 min). None of these differences were statistically significant by multivariate analysis.

Conclusion

Our data suggests that there is no reason to delay RALP to more than 4 weeks after prostate biopsy. It also revealed that the number of biopsy cores (up to 14) did not influence operative outcome. Thus, RALP is a feasible procedure regardless of the biopsy related prostate state.

A Matched-cohort Comparison of Laparoscopic Renal Cryoablation using Ultra-thin Cryoprobes with Open Partial Nephrectomy for the Treatment of Small Renal Cell Carcinoma
Young Hwii Ko, Hong Seok Park, Du Geon Moon, Jeong Gu Lee, Je Jong Kim, Duck Ki Yoon, Seok Ho Kang, Jun Cheon
Cancer Res Treat. 2008;40(4):184-189.   Published online December 31, 2008
DOI: https://doi.org/10.4143/crt.2008.40.4.184
AbstractAbstract PDFPubReaderePub
Purpose

To evaluate the feasibility and efficacy of performing laparoscopic renal cryoablation (LRC) for the treatment of RCC, as compared with open partial nephrectomy (OPN), which is the established NSS.

Materials and Methods

From April 2004, among the patients who underwent LRC with a 1.47 mm cryoprobe, we enrolled 20 patients who were pathologically confirmed as having RCC with a tumor size smaller than 4 cm. These patients were matched with a group of 20 patients, who were selected based on the pre-operative characteristics of the tumor and those of the patients, from a pre-existing database of the patients who underwent OPN during the same period.

Results

The mean age and tumor size were 56.3±11.5 years and 2.4±1.7 cm in the LRC group, and 57.6±10.9 years and 2.2±1.1 cm in the OPN group. The two groups were similar for their age, gender, BMI, ASA, the tumor characteristics and the indications for operation. While the pathologic results and the operation time showed similarity, the EBL (98±87 ml vs 351±147 ml, respectively, p=0.001), the transfusion rate (10% vs 40%, respectively, p=0.03) and the hospital stay (4.2±1.5 days vs 8.2±2.4 days, respectively, p=0.005) were significantly less in the LRC group. Major complications did not occur in the LRC group, but in the OPN group, one patient experienced urine leakage and one patient had a perirenal hematoma. During the mean follow up of 27.3±10.8 months and 28.7±14.9 months for each group, respectively, all the patients remained disease-free with no evidence of local recurrence or metastases.

Conclusions

LRC using ultra-thin cryoprobes for the treatment of small RCC showed similar effective oncologic results with the merits of minimal invasiveness, as compared with OPN, during the intermediate term follow up.
