Randomized Controlled Trial Multicenter Study Comparative Study
Improved surgical safety after laparoscopic compared to open surgery for apparent early stage endometrial cancer: results from a randomised controlled trial.
To compare Total Laparoscopic Hysterectomy (TLH) and Total Abdominal Hysterectomy (TAH) with regard to surgical safety. ⋯ Compared to TAH, TLH is associated with a significantly decreased risk of major surgical AEs. A laparoscopic surgical approach to early stage endometrial cancer is safe.

Advances in our understanding of tumour biology have encouraged reassessment of tumour classification by the site of origin in favour of molecular characteristics and/or oncogenic drivers amenable to treatment. The identification of EML4-anaplastic lymphoma kinase (ALK) as an oncogenic driver in non-small cell lung cancer (NSCLC) early in the clinical development of crizotinib and the observation of promising clinical responses in patients with NSCLC harbouring ALK translocations accelerated its clinical development in ALK-positive NSCLC. Phase I and II trials of crizotinib in patients with ALK-positive advanced NSCLC reported notably high response rates that tended to be rapid and of prolonged duration. ⋯ The ability to molecularly select patients likely to respond to an investigational agent argues that future clinical development of targeted agents should be re-evaluated. Updated trial designs incorporating molecular testing, early use of enrichment biomarkers and intermediary endpoints may accelerate and optimise clinical evaluation of targeted agents. Such trial designs should allow rapid clinical evaluation, minimise exposure of patients to therapies unlikely to be of benefit and, potentially, allow accelerated drug approval in molecularly specified populations.

Cholangiocarcinoma (CC) is a rare cancer of the liver. Surgery offers the only chance for cure. When surgery is unfeasible, chemotherapy is the backbone of treatment. The combined administration of cisplatin and gemcitabine is considered standard of care. Human equilibrative nucleoside transporter 1 (hENT1) is the major transporter responsible for gemcitabine uptake into cells. hENT1 expression is associated with an increased survival for patients receiving gemcitabine after pancreatic cancer surgery, suggesting that hENT1 is predictive of response to gemcitabine. ⋯ In this study we show the potential of hENT1 expression as a predictor of outcome in CC treated with gemcitabine. Larger studies are necessary to confirm these promising results.

High hospital volume is associated with better outcomes after oesophagectomy and gastrectomy. In the Netherlands, a minimal volume standard of 10 oesophagectomies per year was introduced in 2006. For gastrectomy, no minimal volume standard was set. Aims of this study were to describe changes in hospital volumes, mortality and survival and to explore if high hospital volume is associated with better outcomes after oesophagectomy and gastrectomy in the Netherlands. ⋯ Oesophagectomy was effectively centralised in the Netherlands, improving mortality and survival. Gastrectomies were mainly performed in low volumes, and outcomes after gastrectomy improved to a lesser extent, indicating an urgent need for improvement in quality of surgery and perioperative care for gastric cancer in the Netherlands.
