However, consensus about the definition, diagnosis and treatment of oligometastatic oesophagogastric cancer is lacking. The aim of this study was to develop a multidisciplinary European consensus statement on the definition, diagnosis and treatment of oligometastatic oesophagogastric cancer. Methods In total, 65 specialists in the multidisciplinary treatment for oesophagogastric cancer from 49 expert centres across 16 European countries were requested to participate in this Delphi study. The consensus finding process consisted of a starting meeting, 2 online Delphi questionnaire rounds and an online consensus meeting. Input for Delphi questionnaires consisted of (1) a systematic review on definitions of oligometastatic oesophagogastric cancer and (2) a discussion of real-life clinical cases by multidisciplinary teams. Experts were asked to score each statement on a 5-point Likert scale. The agreement was scored to be either absent/poor (2 years, either upfront local treatment or systemic treatment followed by restaging was considered as treatment (fair agreement). Conclusion The OMEC project has resulted in a multidisciplinary European consensus statement for the definition, diagnosis and treatment of oligometastatic oesophagogastric adenocarcinoma and squamous cell cancer. This can be used to standardise inclusion criteria for future clinical trials.

Colorectal cancer is one of the most frequent cancers in the world and between 50% and 60% of patients will develop colorectal liver metastases (CRLM) during the disease. There have been great improvements in the management of CRLM during the last decades. The combination of modern chemotherapeutic and biological systemic treatments with aggressive surgical resection strategies is currently the base for the treatment of patients considered unresectable until few years ago. Furthermore, several new treatments for the local control of CRLM have been developed and are now part of the arsenal of multidisciplinary teams for the treatment of these complex patients. The aim of this review was to summarize and update the management of CRLM, its controversies and relevant evidence.

Background: The optimal anti-angiogenic strategy as second-line treatment in RAS wild-type metastatic colorectal cancer (mCRC) treated with anti-EGFR (Epidermal Growth Factor Receptor) based first-line treatment is still debated. Methods: This multicenter, real-world, retrospective study is aimed at evaluating the effectiveness of second-line Bevacizumab- and Aflibercept-based treatments after an anti-EGFR based first-line regimen. Clinical outcomes measured were: objective response rate (ORR), progression free survival (PFS), overall survival (OS) and adverse events (AEs) profiles. Results: From February 2011 to October 2019, 277 consecutive mCRC patients received Bevacizumab-based (228, 82.3%) or Aflibercept-based (49, 17.7%) regimen. No significant difference was found regarding ORR. The median follow-up was 27.7 months (95%CI: 24.7&ndash, 34.4). Aflibercept-treated group had a significantly shorter PFS compared to Bevacizumab-treated group (5.6 vs. 7.1 months, respectively) (HR = 1.34 (95%CI: 0.95&ndash, 1.89), p = 0.0932). The median OS of the Bevacizumab-treated group and Aflibercept-treated group was 16.2 (95%CI: 15.3&ndash, 18.1) and 12.7 (95%CI: 8.8&ndash, 17.5) months, respectively (HR= 1.31 (95%CI: 0.89&ndash, 1.93) p = 0.16). After adjusting for the key covariates (age, gender, performance status, number of metastatic sites and primary tumor side) Bevacizumab-based regimens revealed to be significantly related with a prolonged PFS (HR = 1.44 (95%CI: 1.02&ndash, 2.03), p = 0.0399) compared to Aflibercept-based regimens, but not with a prolonged OS (HR = 1.47 (95%CI: 0.99&ndash, 2.17), p = 0.0503). The incidence of G3/G4 VEGF inhibitors class-specific AEs was 7.5% and 26.5% in the Bevacizumab-treated group and the Aflibercept-treated group, respectively (p = 0.0001). Conclusion: Our analysis seems to reveal that Bevacizumab-based regimens have a slightly better PFS and class-specific AEs profile compared to Aflibercept-based regimen as second-line treatment of RAS wild-type mCRC patients previously treated with anti-EGFR based treatments. These results have to be taken with caution and no conclusive considerations are allowed.

Resumen El cancer de mama HER2 positivo supone aproximadamente un 15% de los tumores malignos de mama. La terapia anti-HER2, principalmente representada por trastuzumab, es el pilar del tratamiento de esta enfermedad. La prolongacion en la supervivencia que han conseguido las nuevas terapias anti-HER2, y el tratamiento dilatado de estas pacientes en los estadios precoces de la enfermedad asi como en la enfermedad avanzada, supone un importante reto a los recursos existentes, tanto con respecto al personal sanitario y el tiempo de los hospitales de dia oncologicos, como en cuanto al tiempo dedicado por las pacientes para su tratamiento. El desarrollo de una formulacion subcutanea ha supuesto una disminucion significativa en la utilizacion de estos recursos y facilidad de uso. En esta revision, presentamos el desarrollo de esta nueva formulacion, asi como los datos de eficacia y preferencia.

A 69 year old man with idiopathic chronic kidney disease was diagnosed with relapsing EGFR negative, ALK positive lung adenocarcinoma, and treated with chemotherapy and antiangiogenic treatment, under which his renal insufficiency worsened. During second line crizotinib treatment, further worsening of the renal function was seen, with very clear correlation with crizotinib withdrawal and rechallenge. No further drug causes for the worsening blood creatinine values were detected.
