Randomized Controlled Trial Multicenter Study Comparative StudyShort-term outcomes of complete mesocolic excision versus D2 dissection in patients undergoing laparoscopic colectomy for right colon cancer (RELARC): a randomised, controlled, phase 3, superiority trial.
Whether extended lymphadenectomy for right colon cancer leads to increased perioperative complications or improves survival is still controversial. This trial aimed to compare the efficacy and safety of complete mesocolic excision (CME) versus D2 dissection in laparoscopic right hemicolectomy for patients with right colon cancer. This article reports the early safety results from the trial. ⋯ The Capital Characteristic Clinical Project of Beijing and the Chinese Academy of Medical Sciences.

Randomized Controlled Trial Multicenter Study Comparative StudyPyrotinib plus capecitabine versus lapatinib plus capecitabine for the treatment of HER2-positive metastatic breast cancer (PHOEBE): a multicentre, open-label, randomised, controlled, phase 3 trial.
Despite therapeutic advances in HER2-positive metastatic breast cancer, resistance to trastuzumab inevitably develops. In the PHOEBE study, we aimed to assess the efficacy and safety of pyrotinib (an irreversible pan-HER inhibitor) plus capecitabine after previous trastuzumab. ⋯ For the Chinese translation of the abstract see Supplementary Materials section.

Randomized Controlled Trial Multicenter Study Comparative Study4 Gy versus 24 Gy radiotherapy for follicular and marginal zone lymphoma (FoRT): long-term follow-up of a multicentre, randomised, phase 3, non-inferiority trial.
The optimal radiotherapy dose for indolent non-Hodgkin lymphoma is uncertain. We aimed to compare 24 Gy in 12 fractions (representing the standard of care) with 4 Gy in two fractions (low-dose radiation). ⋯ Cancer Research UK.

Randomized Controlled Trial Multicenter StudyCirculating tumour DNA in patients with advanced melanoma treated with dabrafenib or dabrafenib plus trametinib: a clinical validation study.
Melanoma lacks validated blood-based biomarkers for monitoring and predicting treatment efficacy. Cell-free circulating tumour DNA (ctDNA) is a promising biomarker; however, various detection methods have been used, and, to date, no large studies have examined the association between serial changes in ctDNA and survival after BRAF, MEK, or BRAF plus MEK inhibitor therapy. We aimed to evaluate whether baseline ctDNA concentrations and kinetics could predict survival outcomes. ⋯ Novartis.
