Background: Anemia is the most common hematologic abnormality in bladder cancer (BC) patients. We evaluated the impact of preoperative anemia on oncologic outcomes in BC undergoing transurethral resection of a bladder tumor (TURBT) for the first time diagnosis. Materials and Methods: We retrospectively evaluated the data collected from 639 patients who underwent TURBT between January 2006 and September 2014 in our department. Of these patients, 320 qualified for inclusion in the study. The primary efficacy endpoint was the effect of preoperative anemia status on cancer-specific and overall survival. Independent t-test and chi-square analyses were performed to assess the effects of anemia on oncologic outcomes. Survival was estimated by using the Kaplan-Meier test. Results: There were 118 (36.9%) and 202 (63.1%) patients in the anemia (Group-1) and non-anemia groups (Group-2), respectively. The median follow-up duration was 68 months. Anemia was associated with decreased overall survival (p<0.001). Comparison between cancer-specific survival of two groups did not show any statistically significant difference (p=0.17). Conclusions: Preoperative anemia status of BC patients according to World Health Organization classification is associated with decreased overall survival, but not with cancer-specific survival. We think that preoperative hemoglobin levels should be considered in patient counseling and decision-making for additional therapy.

Background: Upper tract transitional cell carcinomas (UTCC) are relatively uncommon but prognosis is generally worse than TCC of bladder. Methods: Between March 2004 and June 2012, patients with initial non-metastatic UTCC were assessed in the Medical Oncology and Urology Departments of Ataturk Training and Research Hospital. Results: A total of 11 patients with initially non-metastatic UTCC were detected in the 8 year period, all males. Median age of was 62 (range, 38-74). Six lesions were located in the renal pelvis and 5 in the ureter. Nephroureterectomy was performed in 9 patients, and distal ureterectomy and cuff excision of the bladder in the remaining 2. The majority (n= 9) had high grade tumors. Median primary tumor diameter was 3.5 cm (range, 0.7-10). Five patients (45.5%) were stage I, 2 (18.2%) were stage II, and 4 (36.4%) were stage III. While adjuvant chemotherapy was not applied for stage I and II disease (n= 7), 4 to 6 courses were applied for 3 of the stage III patients. Also one stage III case received adjuvant radiotherapy. Up to 100 months follow-up, median overall survival was 13 months (range, 5-100 months). While stage I and II patients are following-up without muscle-invasive progression, 2 of stage III patients demonstrated progression. Conclusion: We need more collaborative studies to determine management of especially pT3-pT4 patients with UTCC.

Ten patients with deep muscle-invading bladder carcinoma (clinical stages T3a to T4b) who were not candidates for cystectomy were treated with combined modality treatment with transurethral resection, cisplatin chemotherapy and pelvic irradiation from 1989 through 1990, and were analyzed retrospectively. All patients were not candidates for cystectomy because the tumors were judged unresectable or they were not fit for a radical cystectomy. Of the patients 5 had clinical stage T3a, 3 stage T3b and 2 stage T4b disease. The minimum follow-up was 16 months. The complete response rate is 60$\%$ for all patients. The complete responses were achieved in 4 of 5(80$\%$) with stage cT3a, in 2 of 3(67$\%$)with stage cT3b and in none of 2(0$\%$) with stage cT4b. The partial responses were achieved in 2, so an overall response rate was 80$\%$. All six patients with grade I or II transitional cell carcinoma showed complete responses. Four patients with higher grade tumors showed partial responses in 2 and no response in 2, and all died of their bladder cancer. Six patients who showed complete responses after treatment are alive and only one of them showed a local recurrence 10 months after treatment. Distant metastases developed in 3 patients: lungs in 2(cT4b) of those who were never locally free of disease and spine in 1 patient (cT3b) among those with a partial response. Two patients died of metastases to lungs. During the follow-up diarrhea occurred in one which was improved after conservative treatment. On the basis of this analysis it is suggested that combined modality treatment seems to be a tolerable regimen and can be offered with a relatively high probability of success and conservation of bladder function in those with less advanced tumors by clinical stage and low grade.

[ $\underline{Purpose}$ ]: This study analyzed the tumor response, overall survival, progression free survival and related prognostic factors in patients with muscle invasive bladder cancer subjected to bladder preserving treatment. $\underline{Materials\;and\;Methods}$: Between August 1995 and June 2004, 37 patients with muscle invasive (transitional cell carcinoma, clinically stage T2-4) bladder cancer were enrolled for the treatment protocol of bladder preservation. There were 33 males and 4 females, and the median age was 67 years (range $38{\sim}86\;years$). Transurethral resection of the bladder (TURB) was performed in 17 patients who underwent complete resection. The median radiation dose administered was 64.8 Gy (range $55.8{\sim}67\;Gy$). The survival rate was calculated by the Kaplan-Meier method. $\underline{Results}$: An evaluation of the response rate was determined by abdomen-pelvic CT and cystoscopy at three months after radiotherapy. A complete response was seen in 17 patients (46%). The survival rate at three years was 54.7%, with 54 months of median survival (range $3{\sim}91$ months). During the study, 17 patients died and 13 patients had died from bladder cancer. The progression free survival rate at three years was 37.2%. There were 24 patients (64.9%) who had disease recurrence: 16 patients (43.2%) had local recurrence, 6 patients (16.2%) had a distant recurrence, and 2 patients (5.4%) had both a local and distant recurrence. The survival rate (p=0.0009) and progression free survival rates (p=0.001) were statistically significant when compared to the response rate after radiotherapy. $\underline{Conclusion}$: The availability of complete TURB and appropriate chemoradiotherapy were important predictors for bladder preservation and survival.

Purpose: Urinary cytology and cystoscopic exam are effective methods for diagnosis of transitional cell carcinoma(TCC). But the former shows drawbacks such as the need for a well-trained examiner, and wide imprecision related to the variability of microscopic exam; the latter is an invasive method. $UBC^{TM}$ test detects the epitope on specific cytokeratin fragments released from epithelium of bladder cancer by immunoradiometric assay. We compared $UBC^{TM}$ test with urinary cytology for diagnosis of TCC to evaluate the utility of $UBC^{TM}$ test. Materials and Methods: Eighty-four patients with hematuria were included in our study. $UBC^{TM}$ tests (IDL Biotech, Sweden) were assayed in mid-stream urine according to the ordinary assay protocol. Nineteen patients were confirmed as TCC by cystoscopic examination and underwent transurethral resection (Group A). Other patients had various benign urinary tract conditions (Group B). Samples were considered positive as the $UBC^{TM}$ concentration was greater than $12{\mu}g/L$. Results: $UBC^{TM}$ levels were significantly different between group A ($95.9{\pm}166.4\;{\mu}g/L$) and group B ($19.2{\pm}85.6{\mu}g/L$) (P<0.001). Sensitivity for diagnosis of TCC was 89.5% (17/19) in UBC test and 47.4% (9/19) in cytology (p<0.05). Specificity for diagnosis of TCC was 81.5% (53/65) in $UBC^{TM}$ test and 100% (65/65) in cytology. $UBC^{TM}$ test was significantly more sensitive in stage Ta, $T_1$ tumors (84.6 vs 38.5%, p<0.05) and in grade I (83.3% vs 16.7%, p<0.05) than cytology. $UBC^{TM}$ test showed a tendency to be more sensitive as the grade was higher (83.3% in Grade I, 90% in Grade II and 100% in Grade III). Conclusion: $UBC^{TM}$ test could be a useful method in distinguishing TCC from other benign genitourinary diseases. Moreover, $UBC^{TM}$ test could be an especially valuable marker for diagnosis of TCC in patients with early TCC of low grade TCC compared to urinary cytology. Therefore, mbined use of $UBC^{TM}$ test in association with cytology is helpful to overcome the limited sensitivity of cytology.

Purpose: The purpose of the study was to investigate traumatic urethral injury in a 63-year-old patient with hematuria. Methods: A hematuria patient was transferred by paramedics. At the time of the visit, the patient's blood pressure (151/91mmHg), pulse rate (86/min), body temperature (37.1℃), and other vital signs were stable. Their KTAS (Korean Triage and Acuity Scale) was Level 4. The patient had no damage to the injured area, but a large contrast defect was observed between the prostate urethra and the bladder in urethral angiography performed due to persistent hematuria and pain in the injured area. Results: Following radiological evaluation of a suspected liposarcoma or neuroma mass of the prostate urethra, the mass was removed through urethral tumor resection. The result of histologic evaluation provided a diagnosis of highly differentiated invasive urethral cell carcinoma that had invaded the muscle layer. The patient was given additional treatment for urethral cancer but was rejected and is currently being followed. Conclusion: The prognosis for urinary tract cancer has distinct differences for patients with lymph node metastasis and tumor characteristics. The presence or absence of urethral cancer should be confirmed through angiography, CT, MRI, and cystoscopy.

Purpose : This study analyzed the prognostic factors affecting the survival rate and evaluated the role of radiation therapy in muscle-invading bladder cancer. Materials and Methods : Twenty eight patients with bladder cancer who completed planned definitive radiotherapy in the Departments of Therapeutic Radiology and Urology, Chonnam National University Hospital between Jan. 1986 to Dec. 1998 were retrospectively analyzed. The reviews were peformed based on the patients' medical records. There were 21 males and 7 females in this study. The median of age was 72 years old ranging from 49 to 84 years. All patients were confirmed as having transitional cell carcinoma with histological grade 1 in one patient, grade 2 in 15, grade 3 in 9, and uninformed in 3. Radiation therapy was peformed using a linear accelerator with 6 or 10 MV X-rays. Radiation was delivered daily with a 1.8 or 2.0 Gy fraction size by 4 ports (anterior-posterior, both lateral, alternatively) or 3 ports (Anterior and both lateral). The median radiation dose delivered to the isocenter of the target volume was 61.24 Gy ranging from 59 to 66.6 Gy. The survival rate was calculated by the Kaplan-Meier method. Multivariate analysis was peformed on the prognostic factors affecting the survival rate. Results : The survival rate was $76\%,\;46\%,\;33\%,\;33\%$ at 1, 2, 3, 5 years, respectively, with 19 months of median survival. The potential factors of age (less than 70 years vs above 70), sex, diabetes mellitus, hypertension, hydronephrosis, 1-stage (T3a vs T3b), TUR, chemotherapy, total duration of radiotherapy, radiation dose (less than 60 Gy vs above 60 Gy), and the treatment response were investigated with uniand multivariate analysis. Un univariate analysis, the T-stage (p=0.078) and radiation dose (p=0.051) were marginally significant, and the treatment response (p=0.011) was a statistically significant factor on the survival rate. Multivariate analysis showed there were no significant prognostic factors affecting the survival rate. Conclusion : The treatment response and radiation dose are suggested as th은 statistically significant factors affecting the survival rate of muscle invasive bladder cancer. A Further prospective randomized study is needed to confirm these prognostic factors.

Purpose : This is a retrospective analysis for pattern of failure, survival rate and prognostic factors of 114 patients with histologically proven invasive cancer of the uterine cervix treated with definitive irradiation. Materials and Methods : One hundred fourteen patients with invasive carcinoma of the cervix were treated with a combination of intracavitary irradiation using Fletcher-Suit applicator and external beam irradiation by 6MV X-ray at the Ewha Womans University Hospital between March 1982 and Mar 1990. The median age was 53 years(range:30-77 years). FIGO stage distribution was 19 for IB, 23 for IIA, 42 for IIB, 12 for IIIA and 18 for IIIB. Summation dose of external beam and intracavitary irradiation to point A was 80-90 Gy(median:8580 cGy) in early stage(IB-IIA) and 85-100 Gy(median:8850 cGy) in advanced stage(IIB-IIIB). Kaplan-Meier method was used to estimate the survival rate and multivariate analysis for progrostic factors was performed using the Log likelihood for Weibull Results : The pelvic failure rates by stage were $10.5{\%}$ for IB. $8.7{\%}$ for IIA, $23.8{\%}$ for IIB, $50.0{\%}$ for IIIA and $38.9{\%}$ for IIIB. The rate of distant metastasis by stage were $0{\%}$ for IB, $8.7{\%}$ for IIA, $4.8{\%}$ for IIB. $0{\%}$ for IIIA and $11.1{\%}$ for IIIB. The time of failure was from 3 to 50 months and with median of 15 months after completion of radiation therapy. There was no significant coorelation between dose to point A($\leq$90 Gy vs >90 Gy) and pelvic tumor control(P>0.05). Incidence rates of grade 2 rectal and bladder complications were $3.5{\%}$(4/114) and $7{\%}$(8/114), respectively and 1 patient had sigmoid colon obstruction and 1 patient had severe cystitis. Overall 5-year survival rate was $70.5{\%}$ and disease-free survival rate was $53.6{\%}$. Overall 5-year survival rate by stage was $100{\%}$ for IB, $76.9{\%}$ for IIA, $77.6{\%}$ for IIB $87.5{\%}$ for IIIA and $69.1{\%}$ for IIIB. Five-rear disease-free survival rate by stage was $81.3{\%}$ for IB, $67.9{\%}$ for IIA, $46.8{\%}$ for IIB, $45.4{\%}$ for IIIA and $34.4{\%}$ for IIIB. The prognostic factors for disease-free survival rate by multivariate analysis was performance status(p= 0.0063) and response rate after completion of radiation therapy(p= 0.0026) but stage, age and radiation dose to point A were not siginificant. Conclusion : The result of radiation therapy for early stage of the uterine cervix cancer was relatively good but local control rate and survival rate in advanced stage were poor inspite of high dose irradiation to point A above 90 Gy. Prospective randomized studies are recommended to establish optimal tumor doses for various stages and volume of carcinoma of uterine cervix, And ajuvant chemotherapy or radiation-sensitizing agents must be considered to increase the pelvic control and survival rate in advanced cancer of uterine cervix.
