The use of epidermal growth factor receptor inhibitors to treat metastatic colorectal cancer (mCRC) patients requires prior confirmation of tumour wild type (WT) RAS mutation status (exons 2/3/4 for KRAS or NRAS). This retrospective pooled analysis aims to robustly estimate RAS mutation prevalence and individual variation patterns in mCRC patients. ⋯ This analysis provides robust estimates of overall RAS mutation prevalence and individual variation patterns in mCRC patients.

Multicenter Study Comparative Study
Early surgery for failure after chemoradiation in operable thoracic oesophageal cancer. Analysis of the non-randomised patients in FFCD 9102 phase III trial: Chemoradiation followed by surgery versus chemoradiation alone.
Two randomised trials concerning thoracic oesophageal cancer concluded that for squamous cell carcinoma, chemoradiation alone leads to the same overall survival (OS) as chemoradiation followed by surgery. One of these trials, FFCD 9102, randomised only fit, compliant and operable responders to induction chemoradiation between continuation of chemoradiation and surgery. In the present analysis, the outcome in the patients not eligible for randomisation was calculated to determine if attempt of surgery should be recommended. ⋯ In patients with locally advanced thoracic oesophageal cancer, overall survival did not differ between responders to induction chemoradiation and patients having surgery after clinical failure of chemoradiation. Surgery should therefore be considered in those patients who are still operable.

Review Practice Guideline
Formalised consensus of the European Organisation for Treatment of Trophoblastic Diseases on management of gestational trophoblastic diseases.
Gestational trophoblastic disease (GTD) is a spectrum of cellular proliferations arising from trophoblast. Their invasive and metastatic potential sometimes requires chemotherapy and/or surgery. Current management is generally associated with favourable prognosis. ⋯ There was an agreement for 54 statements while the experts showed a disagreement for two statements. As there is little evidence from randomised trials on which to base recommendations about management of GTD, many of these recommendations are based on expert opinion derived from changes in management fact that have improved outcomes from nearly 100% fatality to nearly 100% cure rates. However, a large agreement among experts is invaluable to the individual clinician who is struggling to decide whether a fertility-sparing treatment of hydatidiform mole or a low-risk GTN can be chosen and how it must be conducted.

Multicenter Study Historical Article Observational Study
Effect of time to sentinel-node biopsy on the prognosis of cutaneous melanoma.
In patients with primary cutaneous melanoma, there is generally a delay between excisional biopsy of the primary tumour and sentinel-node biopsy. The objective of this study is to analyse the prognostic implications of this delay. ⋯ Early sentinel-node biopsy is associated with worse survival in patients with cutaneous melanoma.

Multicenter Study
PanGen-Fam: Spanish registry of hereditary pancreatic cancer.
To describe the organisation of the registry and the preliminary results in terms of characteristics of high-risk pancreatic ductal adenocarcinoma (PDAC) families recruited to date and findings of the screening programme. To compare early onset sporadic cases (⩽50 years), sporadic cases (>50 years) and cases with family history of cancer, for PDAC possible risk factors. ⋯ The identification and recruitment of PDAC high-risk families into the PanGen-Fam registry provides an opportunity to detect early onset cancer and precursor pancreatic cancer lesions at a potentially curative stage and to increase the knowledge of the natural history of the disease.
