In the present study, we analyzed Programmed Death Ligand-1 (PD-L1) expression in radical cystectomy (RC) specimens from patients with muscle-invasive urothelial carcinoma (UC), in order to assess any correlations with specific clinicopathological features and its potential prognostic value. A multi-institutional study was performed within the departments of urology and pathology at the Mureș County Hospital, Romania, and Centre Hospitalier Lyon Sud, France. Sixty-nine patients with MIBC were included, for whom tumor histology (conventional versus histological variant/differentiation), tumor extension (T), lymph node involvement (N), and distant metastases (M) were recorded. PD-L1 immunostaining was performed using the 22C3 clone and was interpreted using the combined positive score (CPS) as recommended (Dako Agilent, Santa Clara, CA, USA). Positive PD-L1 immunostaining was more prevalent among UCs with squamous differentiation compared to conventional UCs and trended towards an improved OS (p = 0.366). We found the T stage to be a risk factor for poor survival in PD-L1-positive patients (HR 2.9, p = 0.021), along with the N stage in PD-L1-negative patients (HR 1.98, p = 0.007). No other clinicopathological factor was found to be significantly associated with PD-L1 positivity. Thus, we confirm the need for PD-L1 immunostaining prior to initiating immune checkpoint inhibitor therapy for a more accurate assessment of the patients’ chances of responding to treatment.

Adenocarcinoma is the second most common nonduodenal small bowel tumor. Small bowel adenocarcinoma has risk factors similar to those of colorectal adenocarcinoma but is rarer and less well understood. Diagnosis relies on advanced imaging techniques as well as endoscopy or enteroscopy for tissue diagnosis. Aggressive biology and vague symptoms in early disease cause a majority of patients to present with late-stage disease. Adenocarcinomas with lymph node involvement should be treated with resection and systemic chemotherapy. In contrast, systemic chemotherapy alone should be employed in cases with distant metastases unless the primary tumor is bleeding, perforated, or causing a bowel obstruction.   This review contains 4 figures, 5 tables and 17 references Key words: adenocarcinoma, chemotherapy, enteroscopy, hereditary syndrome, inflammatory bowel disease, lymph node, mesentery, small bowel

Introduction: We aim to review the outcomes of micropapillary urothelial carcinoma (MPUC) of the bladder from a single institution. The hypothesis is that non-muscle-invasive (NMI) MPUC may have a heterogeneous prognosis, and detailed pathological analysis may identify patients that could be managed without immediate cystectomy. Patients and Methods: This is a retrospective analysis of patients presenting with MPUC in a primary transurethral resection specimen (n = 40). The pattern of micropapillary (MP) differentiation [surface/non-invasive (sMP) or invasive (iMP)], extent of MP differentiation and lymphovascular invasion (LVI) were correlated with overall survival (OS), recurrence-free survival and upstaging at re-resection. Results: Sixteen of 40 patients died after a median follow-up of 37 months. Tumour stage was strongly predictive of OS (p < 0.0001). LVI was associated with increased mortality (hazard ratio 12.4, 95% CI: 3.5-44.5, p = 0.0001), higher pathological stage (p = 0.001), lymph node involvement (p = 0.001) and iMP differentiation (p = 0.006). In NMI patients not undergoing cystectomy (n = 17), NMI-sMP compared with NMI-iMP differentiation was associated with an improved OS when compared with iMP (63 vs. 47 months, p = 0.05). Conclusions: MPUC is an aggressive variant of urothelial carcinoma (UC). Similar to conventional UC, LVI associated with MPUC is an adverse prognostic indicator. iMP is a morphological marker for LVI. Histopathological reports should distinguish between sMP and iMP differentiation.

Background: Non-small cell lung cancer (NSCLC) accounts for approximately 80% of new diagnoses of pulmonary carcinoma. This study investigated the correlation between 18 F-fluorodeoxyglucose uptake in computerized tomography integrated positron emission tomography and tumor size, lymph node metastasis, and distant metastasis in patients with NSCLC.Methods: The records of 318 NSCLC patients (220 male, 98 females; mean age 60.94 years) were evaluated retrospectively.Results: 278 cases were adenocarcinomas; 28 squamous cell carcinomas; and 12 large cell carcinoma. When the cases were categorized according to tumor size (group 1, ≤3 cm; group 2, >3 and ≤5 cm; group 3, >5 cm), the maximum standardized uptake value (SUVmax) was significantly lower in groups 1 and 2 compared with group 3 (p<0,001 for each). Considering all cases, tumor SUVmax was not correlated with age, gender or histopathological type. Lymph node metastases were seen in 250 cases: 80.2% of these were adenocarcinomas, 71.4% squamous cell carcinomas, and 58.3% large cell carcinomas. Neither lymph node involvement nor distant metastases were correlated with tumor SUVmax, although lymph node size was positively correlated with lymph node SUVmax (r=0.758; p<0.001).Conclusions: SUVmax was significantly associated with tumor size, but not with distant metastases or lymph node involvement. Therefore, SUVmax on positron emission tomography is not predictive of the presence of metastases.

Background: Several lymph node-related prognosticators were reported in bladder cancer patients with lymph node involvement and receiving radical cystectomy. However, extranodal extension (ENE) remained a debate to predict outcomes. Methods: A retrospective analysis of 1303 bladder cancer patients receiving radical cystectomy and bilateral pelvic lymph node dissection were identified in the National Taiwan Cancer Registry database from 2011 to 2017. Based on the 304 patients with lymph node involvement, the presence of ENE and major clinical information were recorded and calculated. The overall survival (OS) and cancer-specific survival (CSS) were estimated with Kaplan–Meier analysis and compared using the log-rank test. Hazard ratios (HR) and the associated 95% confidence intervals were calculated in the univariate and stepwise multivariable models. Results: In the multivariable analysis, ENE significantly reduced OS (HR = 1.74, 95% CI 1.09–2.78) and CSS (HR = 1.69, 95% CI 1.01–2.83) more than non-ENE. In contrast, adjuvant chemotherapy was significantly associated with better OS and CSS upon the identification of pathological nodal disease. Conclusions: Reduced OS and CSS outcomes were observed in the pathological nodal bladder cancer patients with ENE compared with those without ENE. After the identification of pathological nodal disease, adjuvant chemotherapy was associated with better survival outcomes.
