The Incidence, Management, and Outcome of Penetrating Bladder Injuries in Civilians Resultant from Armed Conflict in Baghdad 2005-2006

The purpose of this paper is to review the diagnosis, treatment, and outcomes of penetrating bladder injuries suffered by civilians in the Iraqi war zone. Materials and Methods. All civilian trauma cases received alive at Al-Yarmouk Teaching Hospital from January 2005 to August 2006 were reviewed for the presence of bladder injury. Results. 533 cases of penetrating abdominal trauma were identified, of which 177 (33%) involved the genitourinary (GU) system and 64 (12%) involved the bladder. Most (70%) were young males, and most (55%) had grade IV injuries. Associated injuries occurred in 63/64 (98%) of patients. 3 patients had missed bladder injuries, and all of these had complications related to their missed injury. Bladder-related complications occurred in 11% of cases, and mortality in 13%, all due to extravesical injuries. Conclusions. Penetrating bladder injury among civilians in Baghdad war zone resulted in 64 cases in 18 months. The initial detection rate is very high (98%), and after primary repair, lasting complications are rare. Morbidities from missed injuries were severe hematuria and vesicorectal fistula. However, (3%) of vesicorectal fistulae healed spontaneously with prolonged bladder drainage. Associated injuries are the rule in penetrating bladder injury patients, and must be diligently investigated and treated

Breast cancer management pathways during the COVID-19 pandemic: outcomes from the UK ‘Alert Level 4’ phase of the B-MaP-C study

Abstract: Background: The B-MaP-C study aimed to determine alterations to breast cancer (BC) management during the peak transmission period of the UK COVID-19 pandemic and the potential impact of these treatment decisions. Methods: This was a national cohort study of patients with early BC undergoing multidisciplinary team (MDT)-guided treatment recommendations during the pandemic, designated ‘standard’ or ‘COVID-altered’, in the preoperative, operative and post-operative setting. Findings: Of 3776 patients (from 64 UK units) in the study, 2246 (59%) had ‘COVID-altered’ management. ‘Bridging’ endocrine therapy was used (n = 951) where theatre capacity was reduced. There was increasing access to COVID-19 low-risk theatres during the study period (59%). In line with national guidance, immediate breast reconstruction was avoided (n = 299). Where adjuvant chemotherapy was omitted (n = 81), the median benefit was only 3% (IQR 2–9%) using ‘NHS Predict’. There was the rapid adoption of new evidence-based hypofractionated radiotherapy (n = 781, from 46 units). Only 14 patients (1%) tested positive for SARS-CoV-2 during their treatment journey. Conclusions: The majority of ‘COVID-altered’ management decisions were largely in line with pre-COVID evidence-based guidelines, implying that breast cancer survival outcomes are unlikely to be negatively impacted by the pandemic. However, in this study, the potential impact of delays to BC presentation or diagnosis remains unknown

Computer-assisted robotic renal surgery

Computer-assisted robotic renal surgery (CARRS) is a minimally invasive surgical treatment option for renal tumors. We review the literature regarding techniques and outcomes and the potential advantages of CARRS. We retrospectively reviewed the literature regarding techniques and outcomes of CARRS, with specific analysis on robotic radical nephrectomy (RRN) and robotic partial nephrectomy (RPN). Multiple papers on RRN and RPN were found where the techniques were performed with either a transperitoneal or a retroperitoneal approach. Preliminary outcomes with RRN and RPN were at least comparable to those of a laparoscopic approach, with some parameters of RPN improved over the laparoscopic approach (warm ischemia time, length of hospital stay and estimated blood loss). CARRS is an emerging field with preliminary outcomes at least comparable to the laparoscopic approach. Large prospective, randomized trials are needed to assess the benefit of CARRS compared with current methods

Current technique and results for extended pelvic lymph node dissection during robot-assisted radical prostatectomy

The practice of extended pelvic lymph node dissection (ePLND) remains one of the most controversial topics in the management of clinically localized prostate cancer. Although most urologists agree on its benefit for staging and prognostication, the role of the ePLND in cancer control continues to be debated. The increased perioperative morbidity makes it unpalatable, especially in patients with low likelihood of lymph node disease. With the advent of robotic assisted laparoscopic prostatectomy, many surgeons were slow to adopt ePLND in the robotic setting. In this study, we summarize the evidence for the prognostic and therapeutic roles of ePLND, review the clinical tools used for lymph node metastasis prediction and survey the numerous experiences of ePLND compiled by robotic urologic surgeons over the years

Comparative effectiveness of neoadjuvant chemotherapy in bladder and upper urinary tract urothelial carcinoma.

OBJECTIVE: To assess the differential response to neoadjuvant chemotherapy (NAC) in patients with urothelial carcinoma of the bladder (UCB) compared to upper tract urothelial carcioma (UTUC) treated with radical surgery. PATIENTS AND METHODS: Data from 1299 patients with UCB and 276 with UTUC were obtained from multicentric collaborations. The association of disease location (UCB vs UTUC) with pathological complete response (pCR, defined as a post-treatment pathological stage ypT0N0) and pathological objective response (pOR, defined as ypT0-Ta-Tis-T1N0) after NAC was evaluated using logistic regression analyses. The association with overall (OS) and cancer-specific survival (CSS) was evaluated using Cox regression analyses. RESULTS: A pCR was found in 250 (19.2%) patients with UCB and in 23 (8.3%) with UTUC (P < 0.01). A pOR was found in 523 (40.3%) patients with UCB and in 133 (48.2%) with UTUC (P = 0.02). On multivariable logistic regression analysis, patients with UTUC were less likely to have a pCR (odds ratio [OR] 0.45, 95% confidence interval [CI] 0.27-0.70; P < 0.01) and more likely to have a pOR (OR 1.57, 95% CI 1.89-2.08; P < 0.01). On univariable Cox regression analyses, UTUC was associated with better OS (hazard ratio [HR] 0.80, 95% CI 0.64-0.99, P = 0.04) and CSS (HR 0.63, 95% CI 0.49-0.83; P < 0.01). On multivariable Cox regression analyses, UTUC remained associated with CSS (HR 0.61, 95% CI 0.45-0.82; P < 0.01), but not with OS. CONCLUSIONS: Our present findings suggest that the benefit of NAC in UTUC is similar to that found in UCB. These data can be used as a benchmark to contextualise survival outcomes and plan future trial design with NAC in urothelial cancer

Clinical impact of COVID-19 on patients with cancer: Data from the COVID-19 and Cancer Consortium (CCC19)

LBA110 Background: There are limited data on COVID-19 in patients with cancer. We characterize the outcomes of patients with cancer and COVID-19 and identify potential prognostic factors. Methods: The COVID-19 and Cancer Consortium (CCC19) cohort study includes patients with active or prior hematologic or invasive solid malignancies reported across academic and community sites. Results: We included 1,018 cases accrued March-April 2020. Median age was 66 years (range, 18-90). Breast (20%) and prostate (16%) cancers were most prevalent; 43% of patients were on active anti-cancer treatment. At time of data analysis, 106 patients (10.4%) have died and 26% met the composite outcome of death, severe illness requiring hospitalization, and/or mechanical ventilation. In multivariable logistic regression analysis, independent factors associated with increased 30-day mortality were age, male sex, former smoking, ECOG performance status (2 versus 0/1: partially adjusted odds ratio (pAOR) 2.74, 95% CI 1.31-5.7; 3/4 versus 0/1: pAOR 5.34, 95% CI 2.44-11.69), active malignancy (stable/responding, pAOR 1.93, 95% CI 1.06-3.5; progressing, pAOR 3.79, 95% CI 1.78-8.08), and receipt of azithromycin and hydroxychloroquine. Tumor type, race/ethnicity, obesity, number of comorbidities, recent surgery, and type of active cancer therapy were not significant factors for mortality. Conclusions: All-cause 30-day mortality and severe illness in this cohort were significantly higher than previously reported for the general population and were associated with general risk factors as well as those unique to patients with cancer. Cancer type and treatment were not independently associated with increased 30-day mortality. Longer follow-up is needed to better understand the impact of COVID-19 on outcomes in patients with cancer, including the ability to continue specific cancer treatments
