Role of Circulating Tumor Cells (CTC), Androgen Receptor Full Length (AR-FL) and Androgen Receptor Splice Variant 7 (AR-V7) in a Prospective Cohort of Castration-Resistant Metastatic Prostate Cancer Patients

Circulating tumor cells (CTC), androgen receptor full-length (AR-FL), and androgen receptor splice variant 7 (AR-V7) are prognostic in patients (pts) with metastatic castration-resistant prostate cancer (mCRPC). AR-V7 seems to predict resistance to androgen-receptor signaling inhibitors (ARSi)

Nasal pressure swings as the measure of inspiratory effort in spontaneously breathing patients with de novo acute respiratory failure.

Background- Excessive inspiratory effort could translate into self-inflicted lung injury, thus worsening clinical outcomes of spontaneously breathing patients with acute respiratory failure (ARF). Although esophageal manometry is a reliable method to estimate the magnitude of inspiratory effort, procedural issues significantly limit its use in daily clinical practice. The aim of this study is to describe the correlation between esophageal pressure swings (\u394P es ) and nasal (\u394P nos ) as a potential measure of inspiratory effort in spontaneously breathing patients with de novo ARF. Methods- From January 1 st , 2021 to September 1 st , 2021, 61 consecutive patients with ARF (83.6% related to COVID-19) admitted to the Respiratory Intensive Care Unit (RICU) of the University Hospital of Modena (Italy) and candidate to escalation of noninvasive respiratory support (NRS) were enrolled. Clinical features and tidal changes in esophageal and nasal pressure were recorded on admission and 24 hours after starting NRS. Correlation between \u394P es and \u394P nos served as primary outcome. The effect of \u394P nos measurements on respiratory rate and \u394P es was also assessed. Results- \u394P es and \u394P nos were strongly correlated at admission (R 2 =0.88, p<0.001) and 24 hours apart (R 2 =0.94, p<0.001). The nasal plug insertion and the mouth closure required for \u394P nos measurement did not result in significant change of respiratory rate and \u394P es . The correlation between measures at 24 hours remained significant even after splitting the study population according to the type of NRS (high-flow nasal cannulas [R 2 =0.79, p<0.001] or non-invasive ventilation [R 2 =0.95, p<0.001]). Conclusions- In a cohort of patients with ARF, nasal pressure swings did not alter respiratory mechanics in the short term and were highly correlated with esophageal pressure swings during spontaneous tidal breathing. \u394P nos might warrant further investigation as a measure of inspiratory effort in patients with ARF

Nomogram-based Prediction of Overall Survival in Patients with Metastatic Urothelial Carcinoma Receiving First-line Platinum-based Chemotherapy: Retrospective International Study of Invasive/Advanced Cancer of the Urothelium (RISC)

The available prognostic models for overall survival (OS) in patients with metastatic urothelial carcinoma (UC) have been derived from clinical trial populations of cisplatin-treated patients

Prognostic Variables in Patients With Non-metastatic Small-cell Neuroendocrine Carcinoma of the Bladder: A Population-Based Study

Small-cell carcinoma of the bladder (SCCB) is a rare, highly aggressive, neoplasm. We retrospectively analyzed the Surveillance, Epidemiology, and End Results (SEER) database to investigate the impact of chemotherapy, surgery, and radiotherapy on overall survival (OS) of patients with non-metastatic SCCB

Subcutaneous metastases from colon cancer: A case report

Introduction: Dukes A stages of colorectal cancer are rarely reported to metastasize. Subcutaneous or skin metastases from colon cancer are rare events and usually indicate widespread disease. Case presentation: We present the case of a 72-year-old Caucasian woman with Dukes A colorectal cancer at diagnosis and, three years later, a single secondary subcutaneous involvement with no other metastatic sites. The description of this case is supported by critical analysis of its clinical, radiological and pathological features. Our report illustrates that diagnosis can be difficult and controversial when relapse occurs in early stage patients and at uncommon sites. Conclusion: The unusual and aggressive course of the reported disease stresses the importance of intensive follow-up in colorectal cancer patients with good prognostic factors. © 2012 Lo-Russo et al.; licensee BioMed Central Ltd
