Purpose: Radical cystectomy (RC) is associated with substantial postoperative morbidity, and unplanned readmission remains common despite advances in perioperative management. However, the association between postoperative readmission due to complications and oncologic outcomes after RC for bladder cancer has not been clearly defined. We evaluated the impact of postoperative readmission on overall survival (OS) and cancer-specific survival (CSS) after RC for bladder cancer. Materials and Methods: We retrospectively analyzed 3,972 patients who underwent RC for bladder cancer in a multicenter cohort. Postoperative readmission was defined as unplanned hospitalization within 90 days postsurgery due to surgery-related complications. Survival outcomes were assessed using the Kaplan-Meier method and compared using the log-rank test. Univariable and multivariable Cox proportional hazards regression analyses were performed to identify independent predictors of OS and CSS. Results: Among the study population, 916 patients (23.1%) experienced postoperative readmission. Baseline and perioperative characteristics were generally comparable between patients with and without readmission. Kaplan-Meier analyses demonstrated significantly worse OS and CSS among patients who experienced postoperative readmission (both log-rank p<0.001). In multivariable analyses adjusting for clinicopathological factors, postoperative readmission remained independently associated with worse OS (hazard ratio [HR], 1.654; 95% confidence interval [CI], 1.464–1.868; p<0.001) and CSS (HR, 1.761; 95% CI, 1.509–2.055; p<0.001). Conclusion Postoperative readmission within 90 days after RC was independently associated with inferior long-term oncologic outcomes. These findings suggest the importance of strategies aimed at preventing postoperative complications and subsequent readmission.

Purpose: Adjuvant chemotherapy (AC) is recommended for muscle-invasive or lymph node-positive upper urinary tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU). However, disease recurrences are frequently observed in pT1 disease, and AC may increase the risk of overtreatment in pT2 UTUC patients. This study aimed to validate a risk-adapted scoring model for selecting UTUC patients with ≤pT2 disease who would benefit from AC. Materials and Methods: We retrospectively analyzed 443 ≤pT2 UTUC patients who underwent RNU. A risk-adapted scoring model was applied, categorizing patients into low- or high-risk groups. Recurrence-free survival (RFS) and cancer-specific survival (CSS) were analyzed according to risk group. Results: Overall, 355 patients (80.1%) and 88 patients (19.9%) were categorized into the low- and high-risk groups, respectively, with the latter having higher pathological stages, concurrent carcinoma in situ, and synchronous bladder tumors. Disease recurrence occurred in 45 patients (10.2%), among whom 19 (5.4%) and 26 (29.5%) belonged to the low- and high-risk groups, respectively (p<0.001). High-risk patients had significantly shorter RFS (64.3% vs. 93.6% at 60 months; hazard ratio [HR] 13.66; p<0.001) and worse CSS (80.7% vs. 91.5% at 60 months; HR 4.25; p=0.002). Multivariate analysis confirmed that pT2 stage and the high-risk group were independent predictors of recurrence and cancer-specific death (p<0.001). Decision curve analysis for RFS showed larger net benefits with our model than with the T stage model. Conclusions The risk-adapted scoring model effectively predicts recurrence and identifies optimal candidates for AC post RNU in non-metastatic UTUC.

Purpose: Although bladder cancer occurs three to 4 times more frequently in men than in women, the relative number of deaths compared to incidence is higher in women, suggesting that women have a worse prognosis than men. Emerging evidence indicates that the activity of the sex steroid hormone pathway may play a role in bladder cancer development, with demonstrations that both androgens and estrogens have biological effects on bladder cancer in vitro and in vivo. This study investigates the influence of sex and menopausal status on recurrence and cancer-specific death (CSD) in bladder cancer patients undergoing radical cystectomy (RC). Materials and Methods: This retrospective analysis included 3,913 patients from the Korean Bladder Cancer Study Group Database who underwent RC between 2010 and 2019. Patients were categorized based on gender and menopausal status (≤50 years: premenopausal; >50 years: postmenopausal). Pathological factors, neoadjuvant chemotherapy, recurrence, and CSD rates were analyzed using chi-square and Fisher exact tests. Results: Among the 3,913 patients, 400 (10.2%) were female. Premenopausal females exhibited significantly lower recurrence rates (28.6%) compared to postmenopausal females (45.7%). CSD rates were similarly reduced in premenopausal females (12.0% vs. 22.2% in postmenopausal females). No significant sex differences in recurrence or CSD were observed among premenopausal patients. Pathological T stage, nodal status, and lymphovascular invasion were significantly associated with recurrence in males, while nodal status alone was significant in females. Neoadjuvant chemotherapy was significantly more frequently administered to male patients under the age of 50, while no difference was observed in the administration of neoadjuvant chemotherapy among female patients based on menopausal status. Conclusion Hormonal changes associated with menopause significantly influence bladder cancer outcomes in women. Premenopausal hormonal environments seem protective, underscoring the need for further research into hormone-driven mechanisms in bladder cancer.

Purpose: This study aimed to evaluate the prognostic value of a trifecta, defined as negative soft tissue surgical margin (STSM), removal of ≥16 lymph nodes, and absence of major complications (Clavien-Dindo classification grade >III) within 90 days, after radical cystectomy (RC), using a large multicenter cohort. Materials and Methods: We retrospectively analyzed data from 3,972 patients with bladder cancer who underwent RC at 11 tertiary centers in South Korea between 2003 and 2024. Survival outcomes, including overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival (RFS), were compared according to trifecta status using Kaplan-Meier and Cox regression analyses. Propensity score matching was performed to adjust for baseline differences. Results: A total of 2,014 eligible patients were included in the final analysis, and the trifecta was achieved in 47.8%. Kaplan-Meier analysis demonstrated significantly improved 5- and 10-year OS (66.7% vs. 62.0%; 62.9% vs. 57.2%; p=0.002), CSS (79.3% vs. 75.4%; 77.8% vs. 73.8%; p=0.008), and RFS (62.7% vs. 57.6%; 60.8% vs. 55.2%; p=0.001) in the trifecta group. In multivariable analysis, trifecta achievement was significantly associated with better OS (HR, 0.813; p=0.008), CSS (HR, 0.787; p=0.017), and RFS (HR, 0.844; p=0.036). Among individual components, negative STSM showed the strongest prognostic effect across all endpoints. Conclusions In this large multicenter study, patients who achieved the RC trifecta exhibited significantly superior survival outcomes compared with those who did not. The trifecta may serve as a practical and standardized metric for assessing surgical quality and performance in RC. Future prospective studies are warranted to validate its prognostic and quality-assurance utility.

Plummer-Vinson syndrome (PVS), also called sideropenic dysphagia or Paterson-Kelly syndrome, is a condition characterized by a triad of chronic iron-deficiency anemia, esophageal webs, and dysphagia. This syndrome is considered as a precancerous condition due to the occurrence of squamous cell carcinoma in the hypopharynx, upper esophagus and oral cavity. Although exact data on the prevalence of the syndrome are not evidently available, physicians need to recognize this rare syndrome. Most of the patients are elderly Caucasian women aged 40 to 70 years, but cases in children, adolescents, or men have also been described. At present, the prevalence of PVS is decreasing due to improvement in nutritional habits and intake of iron supplements. Therefore, the syndrome accompanied with gastric cancer is even more uncommon. We report a case of a 61-year-old woman with PVS who was diagnosed with gastric cancer and improved after treatment.

Pre-operative chemoradiotherapy (CRT) is a preferable treatment option for patients with locally advanced rectal cancer. However, few data are available regarding pre-operative CRT for locally advanced colon cancer. Here, we describe two cases of successful treatment with pre-operative CRT and establish evidence supporting this treatment option in patients with locally advanced colon cancer. In the first case, a 65-year-old woman was diagnosed with ascending colon cancer with duodenal invasion. In the second case, a 63-year-old man was diagnosed with a colonic-duodenal fistula due to transverse colon cancer invasion. These case reports will help to establish a treatment consensus for pre-operative CRT in patients with locally advanced colon cancer.

Laparoscopic surgical approaches, compared with open surgical approaches, provide comparable clinical outcomes, but lower complications. Unfortunately, a rare complication―portomesenteric vein thrombosis―had been reported after laparoscopic surgery. A 42-year-old woman was referred our hospital for recurrent abdominal pain after laparoscopic appendectomy from acute appendicitis. It was determined that abdominal pain was due to postoperative superior mesenteric vein thrombus. A six-month anticoagulation therapy is an excellent treatment for superior mesenteric vein thrombus . Therefore, physicians should be aware of portomesenteric vein thrombosis in patients with newly developed abdominal pain after successful laparoscopic surgical management.

Gaucher disease is a lysosomal storage disease for which enzyme replacement therapy has proven to be effective. A switch-over clinical trial was performed to evaluate the efficacy and safety of Abcertin(R) (ISU Abxis, Seoul, Korea) in subjects with type 1 Gaucher disease who were previously treated with imiglucerase. Five Korean patients with type 1 Gaucher disease were enrolled. Previous doses of imiglucerase ranged from 30 to 55 U/kg every other week. The same dose of Abcertin(R) was administered to all patients for 24 weeks. Primary efficacy endpoints were changes in hemoglobin levels and platelet counts, and the secondary efficacy endpoints included changes in liver and spleen volumes, serum biomarkers, skeletal status and bone mineral density (BMD). During the study period, no statistically significant changes were observed in all parameters including hemoglobin levels and platelet counts, liver and spleen volumes, skeletal status and BMD. Abcertin(R) administration was continued in three patients for another 24 weeks as an extension of the study. Hemoglobin levels and platelet counts were maintained in all three patients. In conclusion, the efficacy and safety of Abcertin(R) are similar to those of imiglucerase, and Abcertin(R) is an effective therapeutic agent for patients with type 1 Gaucher disease (Clinical Trial Registry No. NCT02053896 at www.clinicaltrials.gov).

PURPOSE: This study analyzed QTc prolongation in patients intoxicated from over the counter (OTC) hypnotics compared with prescription hypnotics. METHODS: The medical records of intoxicated patients presented to four emergency centers from January 1, 2010 to December 31, 2010 were retrospectively reviewed. The records of hypnotics overdose patients were selected and investigated for several features: general characteristics, vital signs, past history, ECG findings, treatment methods, ED stay time, drug category and amount, and final results. RESULTS: There were 134 patient cases of OTC hypnotic intoxication (36.9+/-15.1yrs, M:F=37:97), and 270 patient cases of prescription hypnotic intoxication (47.9+/-18.1yrs, M:F=58:212). The ECG QTc upon emergency center admission was 468.4+/-34.8 msec in the OTC hypnotic intoxication group and 449.48+/-26.2 msec in the prescription hypnotic intoxication group (p<0.05). QTc prolongation was noted in 81.3% of patients in the OTC hypnotic intoxication group and 64.1% of patients in the prescription hypnotic intoxication group (p<0.05). CONCLUSION: ECG QTc prolongation was more common from OTC hypnotic intoxication than prescription hypnotics. Close monitoring is therefore recommended for patients who have ingested and overdosed from OTC hypnotics to prevent potentially lethal cardiac toxicity.
