A multicenter, randomized, double-blind, placebo-controlled, phase 3 trial of olanzapine plus triple antiemetic regimen for the prevention of multiday highly emetogenic chemotherapy-induced nausea and vomiting (OFFER study).

Background: Evidence supports prophylactic use of olanzapine for the treatment of chemotherapy-induced nausea and vomiting (CINV). However, most studies to date have focused on patients with single-day highly emetogenic chemotherapy (HEC). Currently, administration of antiemetic therapies for nausea and vomiting induced by multiday chemotherapy regimens remains a challenge.

Treatment patterns and outcomes change in early-stage non-small cell lung cancer in octogenarians and older: a SEER database analysis.

Background: Lung cancer is the most commonly diagnosed cancer and the leading cause of cancer death in the world.

Aims: We used the Surveillance, Epidemiology, and End Results (SEER) database to investigate the changes in the incidence, treatment patterns, and outcomes of early-stage non-small cell lung cancer (NSCLC) in octogenarians and older from 1995 to 2015.

Methods: Using the SEER database, we identified patients ≥ 80 years stage I-IIa NSCLC diagnosed from 1995 to 2015.

c-Myc maintains the self-renewal and chemoresistance properties of colon cancer stem cells.

Cancer stem cells (CSCs) are responsible for cancer formation, recurrence and drug resistance. c-Myc, one of the core markers for stem cells, has recently been considered to serve as a link between malignancy and 'stemness'. However, the precise function of c-Myc in colon CSCs is still unclear.

Prognostic Impact of Different Histological Types on Gastric Adenocarcinoma: a Surveillance, Epidemiology, and End Results Database Analysis.

The clinicopathological characteristics and prognosis of gastric mucinous adenocarcinoma (MAC) and signet ring cell carcinoma (SRC) are still controversial. We designed our study to evaluate the clinicopathologic features and prognosis of MAC, SRC and ordinary gastric adenocarcinoma (OGAC) by analyzing the Surveillance, Epidemiology, and End Results (SEER)-registered database. The 5-year overall survival (OS) of patients with SRC was significantly lower than that of patients with MAC (P = 0.

The recommended treatment strategy for locally advanced gastric cancer in elderly patients aged 75 years and older: a Surveillance, Epidemiology, and End Results database analysis.

Background: As patients aged 75 years and older are often underrepresented in randomized clinical trials, the external validity of clinical trials-based recommendations in older gastric patients was still controversial. The aim of this study is to explore the recommended treatment strategy for locally advanced gastric cancer in elderly patients.

Methods: We designed our study to specifically evaluate the cancer-specific survival (CSS) of four subgroups of patients according to four different treatment modalities: adjuvant radiation (RT), surgery only, RT only and no surgery/no RT by analyzing the Surveillance, Epidemiology, and End Results (SEER)-registered database.

[c-Myc regulation of ATP-binding cassette transporter reverses chemoresistance in CD133(+) colon cancer stem cells].

The present study was aimed to explore the role of c-Myc gene regulation in maintaining the self-renewal and drug-resistant properties of colon cancer stem cells (CSCs) and the underlying mechanism. CD133(+) cells were isolated by flow cytometry cell sorting from human HT29 cancer cells. A small interfering RNA (siRNA) against c-Myc was used, and the mRNA and protein expressions of c-Myc were investigated by real-time PCR and Western blotting, respectively.
