Real-world utilization, patient characteristics, and treatment patterns among men with localized prostate cancer tested with the 17-gene genomic prostate score® (GPSTM) assay.

OBJECTIVES: Descriptive study focusing on real-world utilization and characteristics of men with prostate cancer tested with the 17-gene Genomic Prostate Score® (GPS™) assay by linking administrative claims and electronic health record (EHR) data with GPS results. METHODS: This retrospective, observational cohort study (January 1, 2013 to December 31, 2020) included men aged 40-80 years with localized prostate cancer claims, continuous enrollment in Optum's Integrated Claims data set, ≥1 day of EHR clinical activity, and a GPS result. Men were classified as undergoing definitive therapy (DT) (prostatectomy, radiation, or focal therapy) or active surveillance (AS). AS and DT distribution were analyzed across GPS results, National Comprehensive Cancer Network® (NCCN®) risk, and race. Costs were assessed 6 months after the first GPS result (index); clinical outcomes and AS persistence were assessed during the variable follow-up. All variables were analyzed descriptively. RESULTS: Of 834 men, 650 (77.9%) underwent AS and 184 (22.1%) DT. Most men had Quan-Charlson comorbidity scores of 1-2 and a tumor stage of T1c (index). The most common Gleason patterns were 3 + 3 (79.6%) (AS cohort) and 3 + 4 (55.9%) (DT cohort). The mean (standard deviation) GPS results at index were 23.2 (11.3) (AS) and 30.9 (12.9) (DT). AS decreased with increasing GPS result and NCCN risk. Differences between races were minimal. Total costs were substantially higher in the DT cohort. CONCLUSIONS: Most men with GPS-tested localized prostate cancer underwent AS, indicating the GPS result can inform clinical management. Decreasing AS with increasing GPS result and NCCN risk suggests the GPS complements NCCN risk stratification.

Hypofractionated Radiotherapy as a Standalone Treatment Modality for Locally Advanced Type B2 Thymoma in an Octogenarian Patient: 45 Gy in 15 Fractions.

Thymic epithelial tumors (TETs), particularly type B2 thymomas, are rare neoplasms primarily found in the anterior mediastinum. The current therapeutic approach includes surgery, chemotherapy, and radiotherapy, but there is limited research on radiotherapy as a standalone treatment. This case report aims to elucidate the clinical outcomes of hypofractionated radiotherapy as a standalone treatment for locally advanced type B2 thymoma, offering insights into its potential efficacy and role in clinical practice.

External Fixation as a Primary and Definitive Treatment for Complex Tibial Diaphyseal Fractures: An Underutilized and Efficacious Approach.

Background: External fixation is one of the most often utilized treatment options for complicated tibial diaphyseal fractures (TDF). The purpose of this study was to assess the efficacy of unilateral external fixators as primary and definitive therapy for complex TDF in a resource-limited setting. Materials and Methods: A retrospective study between June 2016 and March 2021 included 110 subjects with TDF who were treated with an external fixator as definitive fixation in hospitals affiliated with Ibb University. The patient's demographic characteristics, complications, and outcomes were gathered and analyzed. Factors associated with pin site infection were also investigated. Results: The mean age was 42.1 ± 10.1 years, with 92.7% being male. Rural residents accounted for 22.7%. Smoking and diabetes mellitus were present in 27.3% and 30.0%, respectively. General complications occurred in 12.0%, with pulmonary embolism being the most common at 4.5%. Orthopedic complications included pin-track infections in 27.3% (30) and osteomyelitis in 1.8% (2). Pin site infections required medical treatment in 21 cases and external fixator changes in five. Two cases each needed several debridements for osteomyelitis and soft tissue. Full union occurred in 79.1% (87) over 23.1 ± 3.2 weeks and final alignment in 97.3% (107) over 34.8 ± 4.8 weeks. Malunions occurred in 1.8% (2), and one case had hypertrophic nonunion. Factors like rural residency, smoking, diabetes, open fractures, worst fracture grade (Gustilo and Anderson type C), and general complications occurrence significantly correlated with pin site infection (all p-values < 0.05). Conclusion: A unilateral external fixator as a primary and definitive treatment is a viable, simple, and effective option for TDF with a high success rate even in a resource-limited setting. In this study, residents in rural areas, smoking, diabetes, open fracture, worst fracture grade, and general complication occurrence were associated with pin site infection occurrence.

Determinants of active surveillance uptake in a diverse population-based cohort of men with low-risk prostate cancer: The Treatment Options in Prostate Cancer Study (TOPCS).

BACKGROUND: Active surveillance (AS) is the preferred strategy for low-risk prostate cancer (LRPC); however, limited data on determinants of AS adoption exist, particularly among Black men. METHODS: Black and White newly diagnosed (from January 2014 through June 2017) patients with LRPC ≤75 years of age were identified through metro-Detroit and Georgia population-based cancer registries and completed a survey evaluating factors influencing AS uptake. RESULTS: Among 1688 study participants, 57% chose AS (51% of Black participants, 61% of White) over definitive treatment. In the unadjusted analysis, patient factors associated with initial AS uptake included older age, White race, and higher education. However, after adjusting for covariates, none of these factors was significant predictors of AS uptake. The strongest determinant of AS uptake was the AS recommendation by a urologist (adjusted prevalence ratio, 6.59, 95% CI, 4.84-8.97). Other factors associated with the decision to undergo AS included a shared patient-physician treatment decision, greater prostate cancer knowledge, and residence in metro-Detroit compared with Georgia. Conversely, men whose decision was strongly influenced by the desire to achieve "cure" or "live longer" with treatment and those who perceived their LRPC diagnosis as more serious were less likely to choose AS. CONCLUSIONS: In this contemporary sample, the majority of patients with newly diagnosed LRPC chose AS. Although the input from their urologists was highly influential, several patient decisional and psychological factors were independently associated with AS uptake. These data shed new light on potentially modifiable factors that can help further increase AS uptake among patients with LRPC.

The impact of marital status on tumor aggressiveness, treatment, and screening among black and white men diagnosed with prostate cancer.

PURPOSE: To examine the association of marital status with prostate cancer outcomes in a racially-diverse cohort. METHODS: The study population consisted of men (1010 Black; 1070 White) with incident prostate cancer from the baseline North Carolina-Louisiana Prostate Cancer (PCaP) cohort. Marital status at time of diagnosis and screening history were determined by self-report. The binary measure of marital status was defined as married (including living as married) vs. not married (never married, divorced/separated, or widowed). High-aggressive tumors were defined using a composite measure of PSA, Gleason Score, and stage. Definitive treatment was defined as receipt of radical prostatectomy or radiation. Multivariable logistic regression was used to examine the association of marital status with (1) high-aggressive tumors, (2) receipt of definitive treatment, and (3) screening history among Black and White men with prostate cancer. RESULTS: Black men were less likely to be married than White men (68.1% vs. 83.6%). Not being married (vs. married) was associated with increased odds of high-aggressive tumors in the overall study population (adjusted Odds Ratio (aOR): 1.56; 95% Confidence Interval (CI): 1.20-2.02) and both Black and White men in race-stratified analyses. Unmarried men were less likely to receive definitive treatment in the overall study population (aOR: 0.68; 95% CI: 0.54-0.85). In race-stratified analyses, unmarried Black men were less likely to receive definitive treatment. Both unmarried Black and White men were less likely to have a history of prostate cancer screening than married men. CONCLUSION: Lower rates of marriage among Black men might signal decreased support for treatment decision-making, symptom management, and caregiver support which could potentially contribute to prostate cancer disparities.

Using Culture Sensitivity Reports to Optimize Antimicrobial Therapy: Findings and Implications of Antimicrobial Stewardship Activity in a Hospital in Pakistan.

Background: There are concerns with inappropriate prescribing of antibiotics in hospitals especially broad spectrum in Pakistan and the subsequent impact on antimicrobial resistance rates. One recognized way to reduce inappropriate prescribing is for empiric therapy to be adjusted according to the result of culture sensitivity reports. Objective: Using culture sensitivity reports to optimize antibiotic prescribing in a teaching hospital in Pakistan. Methods: A retrospective observational study was undertaken in Ghurki Trust Teaching Hospital. A total of 465 positive cultures were taken from patients during the study period (May 2018 and December 2018). The results of pathogen identification and susceptibility testing from patient-infected sites were assessed. Additional data was collected from the patient's medical file. This included demographic data, sample type, causative microbe, antimicrobial treatment, and whether empiric or definitive treatment as well as medicine costs. Antimicrobial data was assessed using World Health Organization's Defined Daily Dose methodology. Results: A total of 497 isolates were detected from the 465 patient samples as 32 patients had polymicrobes, which included 309 g-negative rods and 188 g-positive cocci. Out of 497 isolates, the most common Gram-positive pathogen isolated was Staphylococcus aureus (Methicillin-sensitive Staphylococcus aureus) (125) (25.1%) and the most common Gram-negative pathogen was Escherichia coli (140) (28.1%). Most of the gram-negative isolates were found to be resistant to ampicillin and co-amoxiclav. Most of the Acinetobacter baumannii isolates were resistant to carbapenems. Gram-positive bacteria showed the maximum sensitivity to linezolid and vancomycin. The most widely used antibiotics for empiric therapy were cefoperazone plus sulbactam, ceftriaxone, amikacin, vancomycin, and metronidazole whereas high use of linezolid, clindamycin, meropenem, and piperacillin + tazobactam was seen in definitive treatment. Empiric therapy was adjusted in 220 (71.1%) cases of Gram-negative infections and 134 (71.2%) cases of Gram-positive infections. Compared with empiric therapy, there was a 13.8% reduction in the number of antibiotics in definitive treatment. The average cost of antibiotics in definitive treatment was less than seen with empiric treatment (8.2%) and the length of hospitalization also decreased. Conclusions: Culture sensitivity reports helped reduced antibiotic utilization and costs as well as helped select the most appropriate treatment. We also found an urgent need for implementing antimicrobial stewardship programs in hospitals and the development of hospital antibiotic guidelines to reduce unnecessary prescribing of broad-spectrum antibiotics.

Definitive Chemoradiation Associated with Improved Survival Outcomes in Patients with Synchronous Oligometastatic Esophageal Cancer.

BACKGROUND: The study of oligometastatic esophageal cancer (EC) is relatively new. Preliminary data suggests that more aggressive treatment regimens in select patients may improve survival rates in oligometastatic EC. However, the consensus recommends palliative treatment. We hypothesized that oligometastatic esophageal cancer patients treated with a definitive approach (chemoradiotherapy [CRT]) would have improved overall survival (OS) compared to those treated with a purely palliative intent and historical controls. METHODS: Patients diagnosed with synchronous oligometastatic (any histology, ≤5 metastatic foci) esophageal cancer treated in a single academic hospital were retrospectively analyzed and divided into definitive and palliative treatment groups. Definitive CRT was defined as radiation therapy to the primary site with ≥40 Gy and ≥2 cycles of chemotherapy. RESULTS: Of 78 Stage IVB (AJCC 8th ed.) patients, 36 met the pre-specified oligometastatic definition. Of these, 19 received definitive CRT, and 17 received palliative treatment. With a median follow-up of 16.5 months (Range: 2.3-95.0 months), median OS for definitive CRT and palliative groups were 90.2 and 8.1 months (p < 0.01), translating into 5-year OS of 50.5% (95%CI: 32.0-79.8%) vs. 7.5% (95%CI: 1.7-48.9%), respectively. CONCLUSIONS: Oligometastatic EC patients treated with definitive CRT benefited from that approach with survival rates (50.5%) that vastly exceeded historical standards of 5% at 5 years for metastatic EC. Oligometastatic EC patients treated with definitive CRT had significantly improved OS compared to those treated with palliative-only intent within our cohort. Notably, definitively treated patients were generally younger and with better performance status versus those palliatively treated. Further prospective evaluation of definitive CRT for oligometastatic EC is warranted.

Rural-Urban Disparities in Patient Care Experiences among Prostate Cancer Survivors: A SEER-CAHPS Study.

BACKGROUND: We sought to evaluate rural-urban disparities in patient care experiences (PCEs) among localized prostate cancer (PCa) survivors at intermediate-to-high risk of disease progression. METHODS: Using 2007-2015 Surveillance Epidemiology and End Results (SEER) data linked to Medicare Consumer Assessment of Healthcare Providers and Systems (CAHPS) surveys, we analyzed survivors' first survey ≥6 months post-diagnosis. Covariate adjusted linear regressions were used to estimate associations of treatment status (definitive treatment vs. none) and residence (large metro vs. metro vs. rural) with PCE composite and rating measures. RESULTS: Among 3779 PCa survivors, 1798 (53.2%) and 370 (10.9%) resided in large metro and rural areas, respectively; more rural (vs. large metro) residents were untreated (21.9% vs. 16.7%; p = 0.017). Untreated (vs. treated) PCa survivors reported lower scores for doctor communication (ß = -2.0; p = 0.022), specialist rating (ß = -2.5; p = 0.008), and overall care rating (ß = -2.4; p = 0.006). While treated rural survivors gave higher (ß = 3.6; p = 0.022) scores for obtaining needed care, untreated rural survivors gave lower scores for obtaining needed care (ß = -7.0; p = 0.017) and a lower health plan rating (ß = -7.9; p = 0.003) compared to their respective counterparts in large metro areas. CONCLUSIONS: Rural PCa survivors are less likely to receive treatment. Rural-urban differences in PCEs varied by treatment status.

Introducción: Las fístulas enterocutáneas representan una enfermedad grave que deben afrontar un gran número de cirujanos durante el ejercicio de la profesión. El tratamiento suele ser extremadamente complejo y siempre requiere de una intervención multidisciplinaria adaptada para cada caso en particular. Objetivo: Evaluar las características clínico-epidemiológicas y terapéuticas de las fístulas enterocutáneas posoperatorias. Métodos: Se realizó un estudio observacional, descriptivo, con recogida prospectiva de datos en el quinquenio 2013-2017. El universo fue de 28 pacientes diagnosticados con fístula enterocutánea posoperatoria y se usaron las variables: edad, sexo, carácter de la intervención, diagnóstico operatorio, tipo de fístula, tratamiento definitivo, complicaciones y pilares de tratamiento. Resultados: La edad media fue de 49 años. Las fístulas fueron más frecuentes en el sexo femenino (53,57 por ciento). El 78,57 por ciento de los pacientes fueron intervenidos con carácter de urgencia, y el 25 por ciento tuvieron un diagnóstico operatorio de oclusión intestinal mecánica por bridas seguida de la oclusión intestinal por tumor de colon izquierdo (17,86 por ciento). La hemicolectomía izquierda con anastomosis término-terminal (21,43 por ciento) y la resección intestinal con anastomosis término-terminal (17,86 por ciento) fueron los principales procedimientos quirúrgicos realizados. Conclusiones: Las fístulas de tipo II y de bajo gasto prevalecieron en la serie de casos en una media de tiempo que se corresponde con lo reportado en la literatura. La infección del sitio quirúrgico fue la complicación más observada y los pilares del tratamiento fueron cumplidos en la mayoría de los pacientes prevaleciendo el cierre espontáneo como tratamiento definitivo(AU)

Introduction: Enterocutaneous fistulas are a serious disease that a large number of surgeons must face during the practice of their profession. Their treatment is usually extremely complex and always requires a multidisciplinary intervention adapted to each particular case. Objective: To evaluate the clinical-epidemiological and therapeutic characteristics of postoperative enterocutaneous fistulas. Methods: An observational and descriptive study was performed, with prospective data collection, in the five-year period 2013-2017. The study universe was 28 patients diagnosed with postoperative enterocutaneous fistula. The following variables were used: age, sex, nature of the intervention, operative diagnosis, type of fistula, definitive treatment, complications and treatment cornerstones. Results: The mean age was 49 years. Fistulas were more frequent in the female sex (53.57 percent). 78.57 percent of the patients underwent emergency surgery, while 25 percent had an operative diagnosis of mechanical intestinal occlusion due to adherences, followed by intestinal occlusion due to left colon tumor (17.86 percent). Left hemicolectomy with end-to-end anastomosis (21.43 percent) and intestinal resection with end-to-end anastomosis (17.86 percent) were the main surgical procedures. Conclusions: Type II and low-output fistulas prevailed in the case series at a mean time that corresponds to that reported in the literature. Surgical site infection was the most frequently observed complication, while the treatment cornerstones were fulfilled in most patients, with spontaneous closure prevailing as a definitive treatment(AU)

Prognostic value of baseline 18F-FDG PET/CT in patients with esophageal squamous cell carcinoma treated with definitive (chemo)radiotherapy.

PURPOSE: To investigate the prognostic value of baseline 18F-FDG PET/CT in patients with esophageal squamous cell carcinoma (ESCC) treated with definitive (chemo)radiotherapy. METHODS: A total of 98 ESCC patients with cTNM stage T1-4, N1-3, M0 who received definitive (chemo)radiotherapy after 18F-FDG PET/CT examination from December 2013 to December 2020 were retrospectively analyzed. Clinical factors included age, sex, histologic differentiation grade, tumor location, clinical stage, and treatment strategies. Parameters obtained by 18F-FDG PET/CT included SUVmax of primary tumor (SUVTumor), metabolic tumor volume (MTV), total lesion glycolysis (TLG), SUVmax of lymph node (SUVLN), PET positive lymph nodes (PLNS) number, the shortest distance between the farthest PET positive lymph node and the primary tumor in three-dimensional space after the standardization of the patient BSA (SDmax(LN-T)). Univariate and multivariate analysis was conducted by Cox proportional hazard model to explore the significant factors affecting overall survival (OS) and progression-free survival (PFS) in ESCC patients. RESULTS: Univariate analysis showed that tumor location, SUVTumor, MTV, TLG, PLNS number, SDmax (LN-T) were significant predictors of OS and tumor location, and clinical T stage, SUVTumor, MTV, TLG, SDmax (LN-T) were significant predictors of PFS (all p < 0.1). Multivariate analysis showed that MTV and SDmax (LN-T) were independent prognostic factors for OS (HR = 1.018, 95% CI 1.006-1.031; p = 0.005; HR = 6.988, 95% CI 2.119-23.042; p = 0.001) and PFS (HR = 1.019, 95% CI 1.005-1.034; p = 0.009; HR = 5.819, 95% CI 1.921-17.628; p = 0.002). Combined with independent prognostic factors MTV and SDmax (LN-T), we can further stratify patient risk. CONCLUSIONS: Before treatment, 18F-FDG PET/CT has important prognostic value for patients with ESCC treated with definitive (chemo)radiotherapy. The lower the value of MTV and SDmax (LN-T), the better the prognosis of patients.

Impact of Positive Culture Reports of E. coli or MSSA on De-Escalation of Antibiotic Use in a Teaching Hospital in Pakistan and the Implications.

Background: Antibiotic de-escalation is a key element of antimicrobial stewardship programs that restrict the spread and emergence of resistance. This study was performed to evaluate the impact of positive culture sensitivity reports of E. coli or Methicillin sensitive Staphylococcus aureus (MSSA) on de-escalation of antibiotic therapy. Methods: This prospective observational study was performed on 256 infected patients. The samples were obtained principally from the pus of infected sites for the identification of pathogens and culture-sensitivity testing. The data were collected from patient medical files, which included their demographic data, sample type, causative microbe and antimicrobial treatment as empiric or definitive treatment based on cultures. Data were analyzed using SPSS. Results: Of 256 isolated microbes, 138 (53.9%) were MSSA and 118 were E. coli (46.1%). MSSA showed 100% sensitivity to cefoxitin, oxacillin, vancomycin, fosfomycin, colistin and more than 90% to linezolid (95.3%), tigecycline (93.1%), chloramphenicol (92.2%) and amikacin (90.2%). E. coli showed 100% sensitivity to only fosfomycin and more than 90% to colistin (96.7%), polymyxin-B (95.1%) and tigecycline (92.9%). The high use of cefoperazone+sulbactam (151), amikacin (149), ceftriaxone (33), metronidazole (30) and piperacillin + tazobactam (22) was seen with empiric prescribing. Following susceptibility testing, the most common antibiotics prescribed for E. coli were meropenem IV (34), amikacin (34), ciprofloxacin (29) and cefoperazone+sulbactam (25). For MSSA cases, linezolid (48), clindamycin (30), cefoperazone+ sulbactam IV (16) and amikacin (15) was used commonly. Overall, there was 23% reduction in antibiotic use in case of E. coli and 43% reduction in MSSA cases. Conclusion: Culture sensitivity reports helped in the de-escalation of antimicrobial therapy, reducing the prescribing of especially broad-spectrum antibiotics. Consequently, it is recommended that local hospital guidelines be developed based on local antimicrobial susceptibility patterns while preventing the unnecessary use of broad-spectrum antibiotics for empiric treatment.

Definitive treatment and risk of death among men diagnosed with metastatic prostate cancer at the Veterans Health Administration.

PURPOSE: To assess the potential survival benefit associated with receipt of definitive treatment (radical prostatectomy or radiation), compared to non-definitive treatment (hormonal therapy or chemotherapy) among men with metastatic prostate cancer. METHODS: A cohort of men diagnosed with metastatic (T4/M1/N1 or T4/M1) prostate cancer from 1999 to 2013 in the Veterans Health Administration were identified and followed to December 28, 2014. All-cause and prostate cancer-specific mortality were evaluated at 10 years for the T4/M1/N1 cohort and 8 years for the T4/M1/ cohort. The association of definitive treatment (radical prostatectomy or radiation), compared to non-definitive (hormonal therapy or chemotherapy) with both all-cause and prostate cancer-specific mortality was assessed using inverse probability of treatment weighted (IPTW) multivariable survival analyses. RESULTS: The cohort included 2919 with T4/M1/N1 disease and 1479 men with T4/M1 disease. Receipt of definitive treatment was associated with a reduced risk of 10-year all-cause (Hazard Ratio (HR): 0.61; 95% Confidence Interval (CI): 0.57-0.65) and prostate cancer-specific mortality (HR: 0.50; 95% CI: 0.46-0.55) among men diagnosed with T4/M1/N1 met-astatic disease. Definitive treatment was similarly associated with a reduced risk of all-cause (HR: 0.84; 95% CI: 0.77-0.91) and prostate cancer-specific (HR: 0.81; 95% CI: 0.73-0.90) mortality among men diagnosed with T4/M1 only metastatic disease. CONCLUSIONS: Definitive treatment may improve survival in men diagnosed with metastatic prostate cancer.

Outcome Predictors of Percutaneous Cholecystostomy As Definitive Versus Bridging Treatment for Acute Cholecystitis.

Introduction Percutaneous cholecystostomy (PC) is a treatment option for patients with acute cholecystitis (AC) who are too unwell, or too morbid for laparoscopic cholecystectomy (LC). Some patients have PC as a definitive treatment, whereas others have PC as a bridging treatment prior to LC. The aim of this study is to investigate patient characteristics and mortality among those who received PC as definitive treatment versus bridging treatment. Methods Our study retrospectively reviewed all patients treated with PC for AC from February 2019 to November 2022 at the Torbay and South Devon NHS Foundation Trust, Torquay, England. Fifty patients underwent PC for AC, with 48 patients having follow-up data available for analysis. Of these, 26 patients (54%) only received PC (definitive PC), and 22 patients (46%) later underwent LC (bridging LC). Results In this study, 68.8% of the patients were male, with a mean age of 76 ± 9 years. The overall mean Charlson Comorbidity Index (CCI) score was 4.96 ± 1.12, and the mean American Society of Anesthesiologists (ASA) score was 2.83 ± 0.36. The median PC drain duration was 42 days. Six patients (12.5%) had a recurrence of AC with a mean of 57 days onset after PC insertion. Twelve patients (25%) experienced PC complications: 11 (23%) were minor, involving pain or a dislodged tube, and one (2%) was major, resulting in a subhepatic abscess. The median duration from PC insertion to LC surgery was 50.5 days. The bridging LC cohort had a 30-day and one-year mortality of 0%, while the definitive PC cohort had a 30-day mortality of 30.8% (eight patients) and a one-year mortality of 46.1% (12 patients). The bridging LC cohort compared to the definitive PC cohort had a significantly lower CCI (4.39 vs 5.57, p<0.05), and a significantly lower ASA (2.61 vs 3.04, p<0.05). The one-year survival cohort compared to the 30-day mortality cohort had significantly lower ASA (2.71 vs 3.25 p<0.05), and a non-significantly lower CCI (4.66 vs 5.86 p=0.094). The presence of negative predictive factors of respiratory dysfunction and hyperbilirubinemia had higher 30-day and 90-day mortality rates of 31.3% and 37.5%, compared to their absence of 9.4% and 21.4% respectively. Conclusion Our results demonstrate that PC is a safe procedure with a high success rate and low complications. We showed that PC is an effective treatment option for bridging a select cohort of patients to receive a delayed LC. Furthermore, the data suggests ASA and CCI scoring can be used as clinical adjuncts to assess whether bridging patients from PC to LC is appropriate. Finally, ASA, respiratory dysfunction, and hyperbilirubinemia can be used as significant negative predictors of post-PC mortality.

Primary Definitive Treatment versus Ureteric Stenting in the Management of Acute Ureteric Colic: A Cost-Effectiveness Analysis.

Objectives: To analyze the differences in cost-effectiveness between primary ureteroscopy and ureteric stenting in patients with ureteric calculi in the emergency setting. Patients and Methods: Patients requiring emergency intervention for a ureteric calculus at a tertiary centre were analysed between January and December 2019. The total secondary care cost included the cost of the procedure, inpatient hospital bed days, emergency department (A&E) reattendances, ancillary procedures and any secondary definitive procedure. Results: A total of 244 patients were included. Patients underwent ureteric stenting (62.3%) or primary treatment (37.7%), including primary ureteroscopy (URS) (34%) and shock wave lithotripsy (SWL) (3.6%). The total secondary care cost was more significant in the ureteric stenting group (GBP 4485.42 vs. GBP 3536.83; p = 0.65), though not statistically significant. While mean procedural costs for primary treatment were significantly higher (GBP 2605.27 vs. GBP 1729.00; p < 0.001), costs in addition to the procedure itself were significantly lower (GBP 931.57 vs. GBP 2742.35; p < 0.001) for primary treatment compared to ureteric stenting. Those undergoing ureteric stenting had a significantly higher A&E reattendance rate compared with primary treatment (25.7% vs. 10.9%, p = 0.02) and a significantly greater cost per patient related to revisits to A&E (GBP 61.05 vs. GBP 20.87; p < 0.001). Conclusion: Primary definitive treatment for patients with acute ureteric colic, although associated with higher procedural costs than ureteric stenting, infers a significant reduction in additional expenses, notably related to fewer A&E attendances. This is particularly relevant in the COVID-19 era, where it is crucial to avoid unnecessary attendances to A&E and reduce the backlog of delayed definitive procedures. Primary treatment should be considered concordance with clinical judgement and factors such as patient preference, equipment availability and operator experience.

Emergency Primary Ureteroscopy for Acute Ureteric Colic-From Guidelines to Practice.

OBJECTIVE: To review the factors that may influence the ability to achieve the present guidelines' recommendations in a well-resourced tertiary centre. According to current National Institute for Health and Care Excellence (NICE) guidelines, definitive treatment (primary ureteroscopy (URS) or shock wave lithotripsy (ESWL)) should be offered to patients with symptomatic renal colic that are unlikely to pass the stone within 48 h of diagnosis. METHODS: Retrospective review of all patients presenting to the emergency department between January and December 2019 with a ureteric or renal stone diagnosis. The rate of emergency intervention, risk factors for intervention and outcomes were compared between patients who were treated by primary definitive surgery vs. primary symptom relief by urethral stenting alone. RESULTS: A total of 244 patients required surgical management for symptomatic ureteric colic without symptoms of urinary infection. Of those, 92 patients (37.7%) underwent definitive treatment by either primary URS (82 patients) or ESWL (9 patients). The mean time for the procedure was 25.5 h (range: 1-118). Patients who underwent primary definitive treatment were likelier to have smaller and distally located stones than the primary stenting group. Primary ureteroscopy was more likely to be performed in a supervised setting than emergency stenting. CONCLUSIONS: Although definitive treatment carries high success rates, in a high-volume tertiary referral centre, it may not be feasible to offer it to all patients, with emergency stenting providing a safe and quick interim measure. Factors determining the ability to provide definitive treatment are stone location, stone size and resident supervision in theatre.

Association Between Receipt of Definitive Treatment for Localized Prostate Cancer and Adverse Health Outcomes: A Claims-Based Approach.

OBJECTIVES: This study aimed to examine adverse health outcomes associated with receipt of definitive treatments (prostatectomy, intensity-modulated radiation therapy [IMRT] and brachytherapy). METHODS: We identified men aged 65 years and older who received a new diagnosis of localized prostate cancer from 4 state cancer registries (CA, FL, NJ, and TX) during the years 2006 to 2013. We merged the registry records for this cohort with Medicare enrollment and claims. We constructed indicators of treatment-related adverse outcomes using diagnosis codes reported on the claims. Stage 1 models the choice of definitive treatment versus active surveillance. Stage 2 examines the probability of experiencing a treatment-related adverse health outcome among men who chose definitive treatment. RESULTS: Notably, 81.4% of our cohort of 61 187 men received definitive treatment whereas 18.6% were monitored with active surveillance. The 5-year prostate cancer death rate was 0.28% to 1.75% irrespective of treatment received. Men monitored with active surveillance experienced minimal adverse health outcomes (0.16%-0.75%). The risks of urinary incontinence associated with prostatectomy were 31 and 39.5 percentage points higher than brachytherapy and IMRT, respectively. For erectile dysfunction, the risks were nearly 23 and 27.5 percentage points higher, respectively, than brachytherapy and IMRT. Prostatectomy was associated with lower risk of urinary dysfunction and bowel dysfunction than either brachytherapy or IMRT. Compared with brachytherapy, IMRT was associated with a lower risk of erectile dysfunction (32%), urinary incontinence (84%), and urinary dysfunction (30%). CONCLUSIONS: This evidence should be of value to patient-physician decision making regarding the choice of definitive treatments versus active surveillance for men with localized disease.

Stereotactic body radiotherapy boost in patients with cervical cancer.

Our aim was to evaluate the oncological outcomes of stereotactic body radiotherapy (SBRT) boost in patients with cervical cancer. The data of 21 patients who received SBRT boost after definitive radiotherapy (RT) or chemoradiotherapy (CRT) between March 2012 and April 2019 were retrospectively evaluated. External beam radiotherapy (EBRT) was applied to patients with a total dose of 50.4 Gy in 28 fractions. Kaplan-Meier method was used for survival analysis (IBM SPSS 23 software) and p < .05 value was considered significant. After definitive RT or CRT, there was a complete response in 9 (43%) patients, partial response in 11 (52%) patients and stable disease in 1 (5%) patient. The median follow-up period was 28 months (range, 7.5-88 months). Two-years cancer-specific survival rate was 80%. While 2-year LC rate was 75% in patients with residual tumour size <4 cm, it was 50% when there was ≥4 cm residual tumour after definitive CRT (p = .1). The treatment was well-tolerated and no acute or late toxicity was observed. Although brachytherapy (BRT) is an essential part of the treatment in locally advanced cervical cancer, SBRT may be used in patients with small residual disease who are not candidate for BRT. IMPACT STATEMENTCervical cancer is one of the most common cancers in the world, and external beam radiotherapy (EBRT) and brachytherapy (BRT) are the main treatment options. However, in rare cases where BRT is not feasible, it has been questioned whether stereotactic body radiotherapy (SBRT) as an alternative to BRT.What is already known on this subject? Nowadays, BRT still appears to be the gold standard treatment. However, studies with a small number of patients and short follow-up periods in the literature show that SBRT can be a good alternative in cases where BRT cannot be performed.What do the results of this study add? Our study is one of the series with the largest number of patients in the literature and with the longest follow-up period. In this area where there is no prospective study, we think that retrospective data with high patient numbers are enlightening.What are the implications of these findings for clinical practice and/or further research? Our study shows that SBRT is an alternative option in cases with small residual disease where BRT cannot be applied, and it provides a basis for a prospective randomised study.

Tratamiento definitivo en traumatismo avulsivo de la región cérvico-facial: presentación de caso clínico / Definitive treatment in avulsive trauma of the cervico-facial region: clinical case report

Resumen Introducción: Las lesiones autoinfligidas por armas de fuego con cañón largo en la zona cérvico-facial no siempre logran consumar el suicidio y pueden ocasionar una herida avulsiva de esta región anatómica. Objetivo: Socializar los beneficios del tratamiento multidisciplinario inmediato en la atención al paciente con traumatismo facial complejo. Caso clínico: Paciente masculino de 60 años de edad con intento autolítico por arma de fuego, con pérdida importante de tejido a nivel mandibular y compromiso de la vía aérea. Resultados: Las distintas etapas de accionar quirúrgico se lograron en las primeras cuatro horas desde que sucedió el incidente. El paciente no presentó complicaciones posoperatorias ni necesidad de una nueva operación. Discusión: En la actualidad existe la tendencia a realizar tratamiento definitivo en un solo tiempo quirúrgico inicial. Conclusión: La intervención inmediata y protocolizada de las especialidades cirugía general, maxilofacial y cirugía plástica-reconstructiva en pacientes con heridas avulsivas de la región cérvico facial pueden lograr un tratamiento definitivo en un único tiempo quirúrgico y con resultados favorables.

Introduction: Self-inflicted injuries by long-barreled firearms in the cervico-facial area do not always succeed in consummating suicide and may result in an avulsive injury of this anatomical region. Aim: Socializing the benefits of the immediate multidisciplinary treatment in the medical care of patients with complex facial trauma. Clinical case: A 60-year-old male patient with an autolytic attempt by firearm, with loss of tissue at the mandibular level, as well as airway compromise. Results: The different stages of the surgical action were achieved during the first four hours since the incident occurred. The patient was discharged without the need for a new surgical procedure. Discussion: Currently there is e tendency to perform definitive treatment in a single initial surgical procedure. Conclusión: The immediate and protocolized intervention of specialties such as General Surgery, Maxillofacial and Plastic-Reconstructive Surgery in patients with avulsive wounds of the cervical-facial region can achieve a definitive treatment in a single surgical time and with favorable results.

Treatment disparities in muscle-invasive bladder cancer: Evidence from a large statewide cancer registry.

OBJECTIVE: To identify patient-level factors that can lead to treatment disparities for muscle invasive bladder cancer, we examine factors associated with receipt of definitive therapy, type of definitive therapy, and neoadjuvant chemotherapy administration in a statewide cohort of muscle-invasive bladder cancer patients. MATERIALS AND METHODS: We identified 2,434 patients diagnosed with non-metastatic muscle-invasive bladder cancer between 2010 and 2015 using the Pennsylvania Cancer Registry. We divided the cohort into three subsamples to examine receipt of treatment: definitive therapy among all muscle-invasive bladder cancer patients (n = 1548), cystectomy (n = 1254) vs. trimodal therapy (n = 294), and neoadjuvant chemotherapy among radical cystectomy patients (n = 1156). Multivariable logistic regression models controlling for patient-level covariates, including insurance status, and socioeconomic disadvantage (based on Area Deprivation Index from census tract data) were estimated to examine factors associated with each treatment outcome. RESULTS: Only 64% of muscle-invasive bladder cancer patients underwent definitive therapy. Those receiving trimodal therapy were more likely to be covered by Medicare than those undergoing cystectomy. Uninsured patients were less likely to undergo definitive treatment and Medicare-insured patients were less likely to undergo cystectomy as their definitive therapy. Patients with greater socioeconomic disadvantage were less likely to receive definitive treatment, undergo cystectomy, or receive neoadjuvant chemotherapy. Over the course of the study period, there was increased neoadjuvant chemotherapy use, but a persistent gap by neighborhood socioeconomic status. CONCLUSIONS: Socioeconomic disadvantage and insurance status are patient-level factors associated with suboptimal treatment for muscle-invasive bladder cancer.

Locally developed external fixators as definitive treatment of open tibia diaphyseal fractures: a clinical prospective study conducted in Ivory Coast.

BACKGROUND: This study sought to evaluate the effectiveness of locally developed external fixators (LDEF) as definitive treatment for open tibia diaphyseal fractures (OTDF) in Ivory Coast. METHODS: Gustilo I, II, and IIIA OTDFs of patients admitted within 24 hours of injury were prospectively included and treated with LDEF. The rates of union, mal-union, septic complications, as well as the functional results were assessed, in addition to the LDEF construct's integrity. Predictive factors of failure or poor results were assessed. RESULTS: Overall, 40 OTDF patients were admitted within 24 hours of injury. Gustilo I, II, and IIIA fractures were observed in three, 13, and 24 patients, respectively. Uneventful fracture healing was obtained in 29 cases, with an average union time of 8.47 months. Mal-union and non-union were registered in three and four cases, respectively. Pin-track infection (PTI) was observed in 13 cases and deep infection in seven. Infection resolved in all patients except four, who developed chronic osteomyelitis. None of the non-unions were associated with an infection. The overall functional result was satisfactory in 32 patients. PTI was the only predictive factor for chronic infection. Biplanar frames, when compared to monoplanar constructs, were associated with a significantly improved functional outcome. CONCLUSION: LDEF improved significantly the OTDF management, as it provided better stability and superior fracture healing rates than what is observed with the standard of care in the same environment. PTI remains an essential problem but with, hopefully, limited negative consequences.
