This phase II randomized clinical trial aimed to assess the efficacy and toxicity of Endostar, an antiangiogenesis inhibitor, combined with concurrent chemoradiotherapy (CCRT) for locally advanced cervical cancer (LACC). Patients with LACC were randomly assigned to either CCRT plus Endostar (CCRT+E arm) or CCRT alone (CCRT arm). All patients received pelvic intensity-modulated radiation therapy (IMRT) and brachytherapy.

Purpose: To evaluate the role of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in predicting early treatment response.

Materials And Methods: Patients with locally advanced cervical cancer (LACC) treated with concurrent chemoradiotherapy (CCRT) were enrolled. Pelvic DCE-MRI scans were performed before RT (pre-RT), in the middle of RT (mid-RT), and at the end of RT (post-RT), separately.

Purpose: We aimed to evaluate the long-term survival outcomes of concurrent chemoradiotherapy (CCRT) combined with nimotuzumab followed by surgery in patients with locally advanced cervical cancer (LACC).

Patients And Methods: Patients received whole pelvic intensity-modulated radiation therapy (IMRT) and concomitantly with weekly cisplatin (40 mg/m) or nedaplatin (30 mg/m) and weekly nimotuzumab (200 mg). After assessment of the treatment response, patients then underwent radical surgery.

Colorectal cancer (CRC) refers to a deadly carcinoma following potent invasiveness and metastasis in advanced stage. Unfortunately, existing anti-CRC medicine is insufficient for chemotherapy in addition to adverse effects. Consequently, the candidate natural ingredient for treating CRC needs to be further developed.

Background: To investigate the efficacy and safety of neoadjuvant chemoradiotherapy plus anti-epidermal growth factor receptor monoclonal antibody followed by surgery for locally advanced cervical cancer (LACC).

Patients And Methods: Patients with histologically proven LACC were enrolled into this prospective study. All patients received intensity-modulated radiation therapy with conventional fractionation.

Article Synopsis
  • Patients with nasopharyngeal carcinoma often undergo significant anatomical changes during intensity-modulated radiation therapy, which may necessitate adaptive radiation therapy to effectively target tumors while protecting critical structures.
  • A study involving 20 patients assessed the benefits of a 3-phase adaptive radiation therapy technique, using repeat CT scans to recalibrate treatment plans after initial radiation doses.
  • Results showed that adaptive radiation therapy significantly improved dose conformity for tumor targets and reduced radiation exposure to surrounding organs, outperforming nonadaptive plans in key dosage metrics.

Article Synopsis
  • This study aimed to find the best timing for adaptive radiation therapy (ART) in treating nasopharyngeal carcinoma (NPC) by analyzing changes in anatomy and dosimetry during treatment.
  • Nineteen NPC patients underwent repeat CT scans, allowing researchers to assess anatomical changes using advanced imaging techniques and generate hybrid treatment plans.
  • Results showed significant reductions in tumor volume and improvements in dose parameters for certain target volumes, while some organs at risk experienced increased radiation exposure, indicating the need for careful monitoring and adjustments in treatment plans.

This study sought to compare the differences in target volumes and dose distributions to the targets and organs at risk (OARs) between a four-dimensional computed tomography (4DCT)-based respiratory-gated intensity-modulated radiation therapy (IMRT) plan (PlanEOE) and a three-dimensional CT (3DCT)-based IMRT plan (Plan3D) in patients with non-small-cell lung cancer (NSCLC). For 17 patients with Stages I-III NSCLC, both 4DCT data and conventional 3DCT data were obtained. The Plan3D and PlanEOE were designed based on 3DCT data and 4DCT data, respectively.

Intrathoracic endotracheal metastasis from a very distant site is extremely rare. We report the first case of such a disease in a 68-year-old man with nasopharyngeal carcinoma who presented with a cough and hemoptysis 34 months after finishing radiotherapy. Prior to tracheal metastasis, he developed a solitary metastasis in the lung and underwent chemotherapy followed by radiotherapy.

The majority of nasopharyngeal carcinoma (NPC) patients present at locally advanced stage. The poor prognosis has led to increasing interests in exploring the use of chemotherapy (CT). Intergroup-0099 trial was the first randomized trial comparing concurrent chemoradiotherapy (CCRT) with radiotherapy (RT) alone.
