Interrelationships between tumor proliferative activity, leucocyte and macrophage infiltration, systemic inflammatory response, and survival in patients selected for potentially curative resection for gastroesophageal cancer.

BACKGROUND: A number of accepted criteria, including pathological tumor, node, metastasis system stage, lymph node metastasis, and tumor differentiation, predict survival in patients undergoing surgery for gastroesophageal cancer. We examined the interrelationships between standard clinicopathological factors, systemic and local inflammatory responses, tumor proliferative activity, and survival. METHODS: The interrelationships between the systemic inflammatory response (Glasgow prognostic score, mGPS), standard clinicopathological factors, local inflammatory response (Klintrup criteria, macrophage infiltration), and tumor proliferative activity (Ki-67) were examined by immunohistochemistry in 100 patients (44 esophageal [19 squamous, 25 adenocarcinoma], 19 junctional, and 37 gastric cancers) selected for potentially curative resection. RESULTS: The minimum follow-up was 59 months. On multivariate survival analysis, lymph node ratio (hazard ratio [HR] 1.63, 95% confidence interval [CI] 1.11-2.40, P < 0.05), tumor differentiation (HR 2.63, 95% CI 1.45-4.77, P = 0.001), mGPS (HR 3.91, 95% CI 1.96-8.11, P < 0.001), Klintrup score (HR 3.47, 95% CI 1.14-10.55, P < 0.05), and Ki-67 (HR 0.67, 95% CI 0.47-0.96, P < 0.05) were independently associated with cancer-specific survival. A higher lymph node ratio was associated with poor tumor differentiation (P < 0.05), low-grade Klintrup criteria (P < 0.005), and low tumor proliferative activity (P < 0.05). CONCLUSION: Tumor proliferation rate and local and systemic inflammatory responses are important predictors of survival, albeit in a heterogeneous cohort of patients including esophageal, junctional, and gastric cancers. These scores may be combined with accepted tumor-based factors to improve prediction of outcome.

Bladder neck and urethral erosions after Macroplastique injections.

AIMS: To evaluate the presentation, risk factors, diagnostic workup, management, and outcomes of Macroplastique (MPQ) erosions. METHODS: We performed a retrospective chart review of women experiencing MPQ erosion at two tertiary care centers (United States and United Kingdom). Data collected included age, presenting symptoms, parity, comorbidities, hormone replacement therapy, sexual activity, and smoking status. Previous surgical history, time from MPQ injection, urine culture results, and cystoscopic and imaging findings were also reviewed. Development of stress urinary incontinence (SUI) after MPQ removal and subsequent SUI treatments were recorded. RESULTS: From 2012 to 2018, 18 patients were identified with a median follow-up time of 24 months (interquartile range [IQR] 8-33). All patients presented with recurrent urinary tract infections (rUTI) and had cystoscopic evidence of MPQ erosion. The most common location of erosion was the bladder neck area (72%). Median time to presentation since MPQ injection was 14 months (IQR 11-35). The majority of patients (72%) had a previous history of anti-incontinence surgery. The overall success rate of endoscopic management defined as resolution of presenting symptoms including rUTI was 80%. The majority of patients (80%) developed recurrent SUI following MPQ resection with 33% requiring a subsequent autologous fascial sling placement. CONCLUSION: MPQ erosions present predominantly with UTI, sometimes years after the original injection, and may necessitate endoscopic management with satisfactory results in most patients. Following excision of MPQ, these patients are highly likely to experience SUI recurrence and need to be appropriately counseled. Some may require additional subsequent autologous fascial sling placement for treatment of their SUI symptoms.

A prospective study of the role of inflammation in bladder cancer.

INTRODUCTION: To examine the role of inflammation in bladder cancer, we assessed the relationship between a systemic inflammation prognostic score (modified Glasgow Prognostic Score, mGPS), the tumor inflammatory cell infiltrate as measured by the Klintrup-Makinen score and tumor necrosis with cancer specific survival in patients with bladder cancer. MATERIALS AND METHODS: The cohort consisted of 68 bladder cancer patients, 47 with localised disease and 21 with muscle invasive disease. The mGPS response was constructed by measuring C-reactive protein and albumin concentrations and the Klintrup-Makinen score was evaluated histologically for the local inflammatory response. Pathological parameters such as grade, T stage and tumor necrosis were also assessed. RESULTS: Median follow was 47 months and 24 patients died of their disease. On univariate analysis, T stage (p < 0.001), grade (p < 0.001) and mGPS (p = 0.002) were significant predictors of cancer specific survival. On multivariate analysis, T stage (hazard ratio 5.98, 95% confidence interval 3.18-11.24, p < 0.001) and mGPS (hazard ratio 1.78, 95% confidence interval 1.09-2.9, p = 0.02) were significant independent predictors of cancer specific survival. CONCLUSION: A preoperative systemic inflammatory response is an independent predictor of poor cancer specific survival in patients with bladder cancer.
