Real-world effectiveness and safety of recombinant human endostatin plus PD-1 inhibitors and chemotherapy as first-line treatment for EGFR/ALK-negative, advanced or metastatic non-small cell lung cancer.

Background: This study aimed to evaluate the effectiveness and safety of recombinant human endostatin (Rh-endostatin) plus programmed cell death 1 (PD-1) inhibitors and chemotherapy as first-line treatment for advanced or metastatic non-small cell lung cancer (NSCLC) in a real-world setting.

Methods: This was a retrospective study on patients with EGFR/ALK-negative, advanced or metastatic NSCLC. Patients received Rh-endostatin plus PD-1 inhibitors and chemotherapy every three weeks for 4 to 6 cycles.

Which Definition of Upper Rectal Cancer Is Optimal in Selecting Stage II or III Rectal Cancer Patients to Avoid Postoperative Adjuvant Radiation?

Background: In most guidelines, upper rectal cancers (URC) are not recommended to take neoadjuvant or adjuvant radiation. However, the definitions of URC vary greatly. Five definitions had been commonly used to define URC: 1) >10 cm from the anal verge by MRI; 2) >12 cm from the anal verge by MRI; 3) >10 cm from the anal verge by colonoscopy; 4) >12 cm from the anal verge by colonoscopy; 5) above the anterior peritoneal reflection (APR).

[The relationship between CD44 and immune escape in gastric carcinoma].

Aim: To study the relationship between CD44 and gastric carcinoma cells.

Methods: The rate and mean fluorecence intension of CD44 cells were detected by flow cytometry.

Results: The rate of CD44' cells was 93.

[Clinical value of the comprehensive treatment in intermediate and advanced cervical cancer with uterine arterial interventional chemoembolization and radiotherapy].

Objective: To investigate the long-term curative effect of the radiotherapy combined uterine arterial interventional chemoembolization for cervical cancer.

Methods: Records of 632 patients with cervical cancer stage II - IVa proved by pathology in Lanzhou Command General Hospital from January 1st, 1999 to August 31st, 2009 were retrospective analysed. One hundred and twenty-six cases of them were treated with radical radiotherapy combined uterine arterial interventional chemoembolization (arterial chemoembolization + radiotherapy group), 506 cases of them were treated with radical radiotherapy only (radiotherapy group); the evaluation of the late radiation injury was done, according to Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer (RTOG/EORTC) advanced radiation injury criteria.
