[New concepts of medical consultation in oncology].

New concepts of medical consultations are currently disrupting the practice of medicine. The use of standardized questionnaires, or patient-reported outcome (PRO and ePRO) has already significantly changed the relationship between the physician and the patient. Telemedicine, or even automatic conversational agents, such as chatbots, are also providing more convenient access to care and medical information for many patients.

To Biopsy or Not to Biopsy?: A Matched Cohort Analysis of Early-Stage Lung Cancer Treated with Stereotactic Radiation with or Without Histologic Confirmation.

Purpose: For nonoperable stage I non-small cell lung cancer, stereotactic body radiation therapy (SBRT) has emerged as a standard treatment option. We aimed to compare the clinical outcomes of lung SBRT between patients with versus without pathologic cancer diagnosis.

Methods And Materials: We included patients treated by SBRT for a single pulmonary lesion between July 2009 and July 2017.

[Stereotactic pulmonary radiotherapy: Which machine?].

Stereotactic radiotherapy represents a fundamental change in the practice of radiotherapy of lung cancers. Despite the great heterogeneity of sites, techniques, and doses, most studies found a high local control rate, around 70 to 90% at 2 years, and reduced toxicity, around 5% of grade 3 at 2 years. Stereotactic radiotherapy can be realized either by a dedicated accelerator (CyberKnife) or by a conventional accelerator associated with specific systems.

[Stereotactic body radiotherapy of oligometastases: Main pending trials and to come in France].

Stereotactic radiotherapy of oligometastases, mono- or hypofractionated, represents a fundamental change in the practice of the specialty as it was developed for a century. Despite the great heterogeneity of sites, techniques, and doses, most studies found a high local control rate, around 70 to 90% at 2 years, and reduced toxicity, around 5% of grade 3 at 2 years. Four main phase II and III trials are underway in France.

Three-year results after radiotherapy for locally advanced sinonasal adenoid cystic carcinoma, using highly conformational radiotherapy techniques proton therapy and/or Tomotherapy.

Purpose: We report the patient outcomes of a treatment combining proton therapy and Tomotherapy in sinonasal adenoid cystic carcinoma involving skull base.

Materials And Methods: We included patients treated at Curie Institute, Paris, France, between March 2010 and February 2014 for an advanced adenoid cystic carcinoma involving skull base. Patients received Tomotherapy, proton therapy or both.
