Psychological Distress, Emergency Room Utilization, and Mortality Risk Among US Adults With History of Prostate Cancer.

Purpose: Adults with a history of prostate cancer experience several physical and mental stressors. However, limited information is available about the prevalence of psychological distress in this population and its association with clinical outcomes in a nationally representative sample.

Methods: We identified adults with history of prostate cancer from a nationally representative cohort (2000-2018 US National Health Interview Survey) and its linked mortality files through December 31, 2019.

Medicaid expansion and racial disparity in timely multidisciplinary treatment in muscle invasive bladder cancer.

Background: Multidisciplinary cancer care (neoadjuvant chemotherapy followed by radical cystectomy or trimodality therapy) is crucial for outcome of muscle-invasive bladder cancer (MIBC), a potentially curable illness. Medicaid expansion through Affordable Care Act (ACA) increased insurance coverage especially among patients of racial minorities. This study aims to investigate the association between Medicaid expansion and racial disparity in timely treatment in MIBC.

POSTN Secretion by Extracellular Matrix Cancer-Associated Fibroblasts (eCAFs) Correlates with Poor ICB Response via Macrophage Chemotaxis Activation of Akt Signaling Pathway in Gastric Cancer.

Immune checkpoint blockade (ICB) therapy has revolutionized cancer treatment, but its clinical benefit is limited in advanced gastric cancer (GC). Cancer-associated fibroblasts (CAFs) have been reported to be associated with ICB resistance, but the underlying mechanism has not been fully elucidated. Our previous single-cell RNA-seq analysis of GC revealed that POSTN+FAP+ extracellular matrix CAFs (eCAFs) communicate with macrophages.

Expression of p53 and Rb reveal subtypes of gastric neuroendocrine carcinoma with distinct prognosis.

Gastric neuroendocrine carcinoma (NEC) is a rare tumor with a poor prognosis. Due to its rarity and disparity in prevalence across populations, there is limited data on gastric NEC. TP53 and RB1 genetic alterations or expression were reported for predictive value in neuroendocrine neoplasm and classification in pulmonary large cell NEC.

Prognostic Factors and Effect of Adjuvant Chemoradiation Following Chemotherapy in Resected Pancreatic Cancer Patients With Lymph Node Metastasis or R1 Resection.

Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease with a poor prognosis. In resectable PDAC, the recurrence rate is still high even when surgery and adjuvant chemotherapy (CT) are applied. Regional lymph node metastasis and positive margins are associated with higher recurrence risk and worse survival.

Systemic treatment of a metastatic carotid body tumor: A case report and literature review.

Rationale: Carotid body tumors (CBTs) are head and neck paragangliomas (PGLs) with a low incidence of distant metastasis. To date, only a few metastatic cases treated with detailed systemic therapy are reported and effective management is still inconclusive. Herein, we reported a metastatic CBT case with systemic therapy and reviewed the reported systemic treatment.

Immune Checkpoint Markers in Neuroendocrine Carcinoma of the Digestive System.

Digestive system neuroendocrine carcinomas (NECs) are rare neoplasms originating from neuroendocrine cells with a poor prognosis and limited effective treatments. Programmed cell death protein 1/ligand 1 (PD-1/PD-L1) blockade has been used in the management of more than 10 solid tumors and has achieved promising clinical outcomes. PD-L1 expression, immune cell infiltration, tumor mutational burden (TMB), and microsatellite instability (MSI) are all verified biomarkers that can predict the response to anti-PD-1/PD-L1 therapy.

CA19-9 elevation as an indication to start salvage treatment in surveillance after pancreatic cancer resection.

Background: CA19-9 is the most commonly used tumor marker in the diagnosis, prognosis and surveillance of pancreatic cancer. We hypothesized that CA19-9 elevation can be taken as an indication to start salvage treatment in surveillance after resection.

Methods: From January 2014 and July 2017, 80 pancreatic cancer patients who underwent R0 surgical resection and received adjuvant chemotherapy were included.
