Conservative management of segmental testicular infarction in a patient with sickle cell anemia: A case report.

Vaso-occlusive crisis is a sequela of sickle cell disease that can lead to severe pain and infarction at the location of occlusion. In men, genitourinary complications include priapism, hematuria, and very rarely, testicular infarction. Few cases have been previously reported in the literature, but in all of those cases, partial or complete orchiectomy was performed. We report the first known case of segmental testicular infarct secondary to sickle cell disease treated with medical management without need for surgical intervention.

Intravesical hexyl-aminolevulinate used to detect upper tract carcinoma in situ during surveillance ureteroscopy: A case report and review.

Blue-light cystoscopy with intravesical hexyl-aminolevulinate has been shown to improve identification of bladder carcinoma. The application of photodynamic techniques in the upper tract has not been well studied. We present a patient with a patulous ureteral orifice allowing for dwelling of photodynamic reagent and cystoscopic evaluation of the distal ureter. This case was significant for blue light fluorescent, biopsy proven upper tract carcinoma in situ that otherwise would have been a benign examination using traditional white light technique. Future work should be done to study the use of photodynamic techniques in the evaluation of upper tract malignancies.

Diagnosis and open excision of concurrent pelvic schwannoma and chromophobe renal cell carcinoma.

Schwannomas are tumors that commonly affect the nerve sheath, typically involving peripheral and cranial nerves. These tumors are rarely found within the pelvis and retroperitoneum. To date, there have been no documented cases of concurrent chromophobe renal cell carcinoma and pelvic schwannoma. We present the case of a 57-year-old female with a right renal mass significant for chromophobe renal cell carcinoma and a left pelvic mass found to be a schwannoma. This case highlights the importance of adding schwannoma to the differential when considering a pelvic mass in the setting of renal cell carcinoma.

Trends of Lymph Node Outcomes in Partial Cystectomy for Muscle-Invasive Urothelial Carcinoma of the Bladder.

INTRODUCTION: Local tumor invasion depth has been associated with lymph node metastasis in urothelial carcinoma, and, for muscle-invasive bladder cancer (MIBC), pelvic lymph node dissection (PLND) is a critical step in curative surgery. Gold standard treatment includes radical cystectomy (RC), but partial cystectomy (PC) is an important bladder-preserving modality reserved for patients with certain favorable prognostic indicators. There is poor evidence concerning the utility of PLND in PC and we seek to further define its role by comparing survival outcomes when PLND was cursory or omitted. METHODS: A retrospective analysis of 13,652 cT2N0M0 patients who underwent PC or RC between 2004 and 2016 was performed using the National Cancer Database. Patients undergoing PC were stratified by the presence of PLND as well as by node yield >15. The primary outcome was overall survival, analyzed using the Kaplan-Meier Method and multivariable Cox-proportional hazards regression. Multivariable models were adjusted for confounding clinicopathologic variables. RESULTS: From 2004 to 2016, PLND in PC increased from 44% to 57% with RC remaining over 90%. Compared to RC, PC was approximately twice as likely to be performed at community centers and approached laparoscopically/robotically (P < .001). When stratifying PC PLND yield into 1 to 15 and > 15 compared to PC without PLND, the adjusted hazard ratios for overall mortality were 0.78 and 0.54, respectively (P < .05). CONCLUSIONS: PC patients had a significantly lower rate of PLND compared to RC and improved survival when performed versus PC alone. Furthermore, increased node yield was associated with a larger reduction of adjusted mortality hazard. For MIBC patients that are appropriately selected for PC, high-yield PLND should be prioritized given the significantly improved survival outcomes.

Radiation-induced myofibroblastoma within the nasal sinus requiring maxillectomy and ethmoidectomy: A case report and literature review.

We report a case of radiation-induced myofibroblastoma of the right nasal cavity in a patient with a remote history of radiotherapy for pediatric retinoblastoma. The patient required maxillectomy and ethmoidectomy. To our knowledge, a rare number of cases have been reported in this location.

Role of Race and Insurance Status in Prostate Cancer Diagnosis-to-Treatment Interval.

INTRODUCTION: Numerous studies have shown that both race and insurance status may affect prostate cancer (PCa) workup and treatment. Preliminary investigations have shown that these factors may be associated with treatment delays, which may indicate inequitable care and increase risk of tumor progression. This investigation aimed to assess whether race and insurance impacted the interval between multiparametric MRI (mpMRI)-to-biopsy, and biopsy-to-prostatectomy. MATERIALS AND METHODS: A single-institution analysis of 261 patients with recorded race and insurance data was performed using an Institutional Review Board-compliant database with information spanning from 2016 to 2022. Race was self-reported during intake, and insurance status was retrieved from the electronic medical record. Insurance was sub-divided into private, Medicare, and Medicaid. Diagnostic or treatment latency was defined as time between mpMRI-to-biopsy, or biopsy-to-surgery. RESULTS: Stratified by race, there was no difference in either latency period when comparing African American (AA) and white patients. Stratified by insurance status, there was no difference in time from mpMRI-to-biopsy (P = .50), but there was a significantly longer interval from biopsy-to-prostatectomy for patients with Medicaid insurance (P = .02). Patients with Medicaid waited on average 168 days to receive surgery, in contrast to 92 days for private and 87 for Medicare. Notably, 82% of Medicaid patients were AA. CONCLUSION: Insurance status, which is inherently linked to race and social determinants of health, portended a significantly increased interval between biopsy and surgery. Physicians should be aware of the relationship between insurance status and treatment delay, as well as its potential downstream consequences.

Association of distance traveled on receipt of surgery in patients with locally advanced rectal cancer.

PURPOSE: Studies have shown patients residing in rural settings have worse cancer-related outcomes than those in urban settings. Specifically, rural patients with colorectal cancer have lower rates of screening and longer time to treatment. However, physical distance traveled has not been as well studied. This study sought to determine disparities in receipt of surgery in patients by distance traveled for care. METHODS: A retrospective cohort study of patients with AJCC stage II/III rectal adenocarcinoma was identified within the National Cancer Database (2004-2017). Primary outcome was correlation of distance traveled to receipt of surgery. Multi-variable logistic regression was used to adjust for confounding factors. RESULTS: 65,234 patients were included in the analysis. 94.6% resided in urban-metro areas while 2.2% resided in rural areas. Patients were predominantly non-Hispanic White (NHW) (75.2%) with an overall median age at diagnosis of 61 (IQR 52-71). Overall, 82.6% of patients received surgery. NHW patients were more likely to receive surgery than non-Hispanic Black patients (OR 0.67; 95% CI 0.61-0.73, p < 0.001), as were patients who were privately insured (OR 1.90, 95% CI 1.67-2.15, p < 0.001) or had Medicare (OR 1.68, 95% CI 1.47-1.92, p < 0.001) compared to uninsured patients. Patients traveling distances in the 4th quartile (median 47.9 miles) were more likely to receive surgery than those traveling the shortest distances (1st quartile: median 2.5 miles) (OR 1.37, 95% CI 1.24-1.50, p < 0.001). CONCLUSION: Patients traveling farther distances were more likely to receive surgery than those traveling shorter distances. Shorter distance traveled does not appear to be associated with higher rates of surgical resection in patients with stage II/III rectal cancer.

Impact of Variant Histology on Occult Nodal Metastasis after Neoadjuvant Chemotherapy for Muscle-Invasive Bladder Cancer: A Review of the National Cancer Database.

Up to 14% of bladder urothelial carcinoma has variant histology (VH), which is associated with a higher incidence of occult regional lymph node metastasis. Neoadjuvant chemotherapy (NAC) is the gold-standard for resectable cT2-4 disease as it achieves pathologic complete response (pCR) in select patients at the time of radical cystectomy (RC). A landmark trial demonstrated chemosensitivity and pT0 status in the setting of VH. pT0N+ pathology in patients undergoing subsequent RC has prompted concerns about post-chemotherapy bladder preservation. We investigate how VH impacts pathologic primary site and nodal downstaging post-NAC. We queried the National Cancer Database for cT2-4N0M0 patients who underwent NAC and RC between 2004 and 2016. These patients were stratified into pure urothelial cell carcinoma (UCC) and VH. The rate of downstaging to ≤pT1 was analyzed, along with pN+ status. Overall survival was analyzed using the Kaplan-Meier method and multivariable Cox proportional hazards regression model. Multivariable models were adjusted for demographic and clinicopathologic variables. Of 5,335 patients, 92.1% were UCC and 7.9% VH. UCC was associated with better unadjusted survival and lower adjusted odds of being pN+ (aOR = 0.60, P < .001). Squamous cell, glandular, and sarcomatoid histologies were significantly associated with decreased adjusted odds of any pT downstage. Neuroendocrine histology (NE) trended towards increased adjusted odds of downstage to pT0N0. Patients with VH were more likely to harbor occult regional lymph node metastasis in the setting of intravesical pCR. NE had the highest pT0N0 rate, with potential implications on post-NAC bladder preservation. These findings reinforce the role of RC after NAC especially for VH.
