목적 : 근 침윤성 방광암에서 생존율에 영향을 주는 예후 인자를 분석하고 방사선 치료의 역할을 알아보고자 하였다. 대상 및 방법 : 1986년 1월부터 1998년 12월까지 전남대학교병원에서 근 침윤성 방광암으로 진단 받고 계획된 치료를 완료한 28명의 환자를 대상으로 후향적 분석을 시행하였다. 전체 28명 중 남자가 21명 여자가 7명이었으며 환자의 연령은 49세에서 84세까지 분포하였고 중앙값은 72세였다. 조직학적으로 모두 이행상피암으로 확진되었으며 grade 1은 1명, grade 2는 15명, grade 3는 9명, 불명인 경우가 3명이었다. 방사선치료는 선형가속기의 6 MV 또는 10 MV X-ray를 이용하였으며 일회선량은 1.8 내지 2.0 Gy로 3문 내지 4문 조사를 시행하였다. 투여된 총방사선량은 59 내지 66.6 Gy였고 중앙값은 61.24 Gy였다. 생존율은 Kaplan-Meier법으로 산출하였고 두 군간의 비교는 Log-rank test를 이용하였다. 생존율에 영향을 미치는 요인들을 Cox 비례위험모델로 다변량 분석하였다. 결과 : 생존율은 1, 2, 3, 5년에 각각 76, 46, 33, $33\%$로 나타났다. 중앙 생존 기간은 19개월이었다. 생존율에 영향을 미치는 가능성 있는 예후 인자로서 연령(70세 미만 대 이상), 성별, 당뇨병, 고혈압, 수신증 동반 여부, T-병기 (T3a 대 T3b 이상), TUR, 항암화학요법 여부, 방사선치료기간, 방사선량(60 Gy 미만 대 60 Gy 이상), 방사선치료반응정도를 분석에 포함시켰으며, 이들 중 단변량분석에서 T-병기(p=0.078)와 방사선량(p=0.051)이 통계학적 의의에 접근하였으며 방사선치료반응 정도(p=0.011)가 통계학적으로 의의 있게 나타났다. 그러나 다변량분석에서는 통계학적 의의를 가지는 인자가 없었다. 결론 : 근 침윤성 방광암에서 생존율에 미치는 예후 인자로 방사선량, 방사선치료반응 정도가 단변량분석에서 의미있게 나타났으나 다변량 분석에서는 확인되지 못하였으며 향후 더욱 많은 증례를 대상으로 이에 대한 전향적 무작위 임상 시험이 필요할 것으로 생각된다.

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.

Summary: We report the first hepatic adverse effect of tosufloxacin tosylate in a muscle invasive bladder cancer patient with normal liver functions and with scheduling to undergo a surgical operation for a neobladder. Tosufloxacin tosylate 150 mg was administered to a 57-year-old man who maintained transurethral resection of bladder tumor (TUR-BT) postoperative multiple medications. His labs presented significant increases in alanine amino transferase (ALT) and aspartate amino transferase (AST) levels with 2-week compliance of 150 mg tablet three times a day. After discontinuing tosufloxacin tosylate, the levels slowly decreased and completely returned to normal ranges without any intervention in a few weeks. The Naranjo Causality Algorithm indicates a probable relationship between increased ALT and tosufloxacin. The patient was to have the second surgical operation as scheduled after getting normal range of ATL level. Therefore, tosufloxacin should be avoided in patients at risk for having liver dysfunctions or diseases if the patients have a schedule for any operation. Background: Tosufloxacin tosylate has been shown to have favorable benefits as an antibiotic. Tosufloxacin tosylate may be considered to have the adverse effects such as nauseas, vomiting, diarrhea, abdominal pain, stomatitis, tendonitis, tendon rupture, headache, dizziness, drowsiness, insomnia, weakness, agitation including hemolysis in the event of glucose-6-phosphate dehydrogenase deficiency as other fluoroquinolones. More severe adverse reactions of tosufloxacin tosylate over the above common adverse effects of fluoroquinolones were thrombocytopenia and nephritis. It also is not well known that tosufloxacin can cause hepatic problem. Here the study reports the first hepatic reaction from tosufloxacin and might arouse heath care providers' attention to appropriate drug choice for patients.

Background: To explore the safety, efficacy, and oncological outcome of 3-port laparoscopic radical cystectomy (LRC) compared to open radical cystectomy (ORC) in patients older than 75 years. Materials and Methods: From June 2010 to July 2014, we analyzed 16 radical cystectomies in patients older than 75 years (LRC group=8; ORC group=8). Demographic parameters, operative variables, and perioperative outcome in the 2 groups were retrospectively collected, analyzed, and compared. Results: Patients in both groups had comparable preoperative characteristics. A significantly longer operating time (476 vs. 303 min, P=0.0002) and less estimated blood loss (627 vs. 2,106 mL, P=0.021) were observed in the LRC group compared to the ORC group. Infection and ileus were the most common early complications after surgery. Patients who underwent ORC suffered from more postoperative infection (22.2% vs. 0.0%, P=0.054) and ileus (25.0% vs. 12.5%, P=0.521) than the LRC group, but the difference was not significant. Conclusions: Judging from this initial trial, 3-port LRC can be safely carried out in elderly patients. We suggest 3-port LRC as the primary intervention to treat muscle-invasive or high-risk nonmuscle-invasive bladder cancer in elderly patients with an otherwise relatively long life expectancy.

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.

Although early studies suggested that bladder cancer (BCa) is more prevalent in men than in women, muscle-invasive rates are higher in women than in men, suggesting that sex hormones might play important roles in different stages of BCa progression. In this work, we found that estrogen receptor beta ($ER{\beta}$) could increase BCa cell proliferation and invasion via alteration of miR-92a-mediated DAB2IP (DOC-2/DAB2 interacting protein) signals and that blocking miR-92a expression with an inhibitor could partially reverse $ER{\beta}$-enhanced BCa cell growth and invasion. Further mechanism dissection found that $ER{\beta}$ could increase miR-92a expression at the transcriptional level via binding to the estrogen-response-element (ERE) on the 5' promoter region of its host gene C13orf25. The $ER{\beta}$ up-regulated miR-92a could decrease DAB2IP tumor suppressor expression via binding to the miR-92a binding site located on the DAB2IP 3' UTR. Preclinical studies using an in vivo mouse model also confirmed that targeting this newly identified $ER{\beta}$/miR-92a/DAB2IP signal pathway with small molecules could suppress BCa progression. Together, these results might aid in the development of new therapies via targeting of this $ER{\beta}$-mediated signal pathway to better suppress BCa progression.

1989년 2월부터 1990년 6월까지 조선대학교 부속병원 치료방사선과에서 침윤성 방광암으로 경요도적절제술 및 Cisplatin과 방사선을 병용하여 치료를 받았던 10예에 대하여 저자는 후향적으로 국소관해율, 생존기간, 치료실패양상 및 부작용을 분석하였다. 이들은 원발병소가 근치적방광절제술이 불가능하였거나, 환자의 전신상태 또는 고령의 나이나 합병된 내과적인 질환때문에 근치적수술을 할 수 없었던 경우였다. 원발병소의 병기는 T3a-T4b였고, N병기는 NO가 9예이고 N1가 1예였으며, 10예 모두 MO 였다. 추적기간은 $16\~32$개월이었다. 수술요법은 경요도적절제술, 화학요법은 Cisplatin $1\~5$회, 방사선치료는 골반부위에 $3960\~5400$ cGy의 선량으로 치료하였다. 원발병소의 병기에 따른 완전관해율은 cT3a에서 80$\%$, cT3b에서 67$\%$ 그리고 cT4b에서 0$\%$였고 전체적으로 60$\%$의 완전관해율을 보였다. 부분관해율은 20$\%$이어서 전체의 국소관해율은 80$\%$였다. 조직학적 검사상모두 이행상피암이었고 조직학적 등급에 따른 완전관해의 차이를보면 I, II등급인 6예에서는 모두 완전관해를 보였고 III, IV등급인 4예에서는 부분관해가 2예이고 무반응이 2예였다. 완전관해를 보였던 6예는 모두 생존하여 있고 이중 1예에서만 치료후 10개월후에 국소재발을 보였다. 완전관해를 보이지 않았던 4예는 모두 조직학적 등급이 III, IV등급으로 방광암으로 사망하였다. 원격전이는 3예에서 보였으며 2예 (cT4b)는 폐, 1예(cT3b)는 척추부위였다. 방사선치료후 부작용은 설사가 가장 심한 부작용으로 1예에서 나타났으나 보존요법으로 호전되었다. 따라서 침윤성방광암에 있어서 방광기능의 보존측면에서 병용치료는 심한 부작용없이 치료가 가능하며 완전관해율을 높이기위하여 방사선선량을 높이고, T4b병기에서는 원격전이 가 큰 문제이므로 효과적인 복합화학요법을 시도하는 것이 필요하다고 사료된다.
