Research paper thumbnail of Recommendations and expert opinion on the adjuvant treatment of colon cancer in Spain

Clinical and Translational Oncology, 2011

The use of oxaliplatin plus 5 fl uorouracil/leucovorin (FOLFOX) or oxaliplatin plus capecitabine-based (XELOX) regimens, both approved in Europe as adjuvant treatment for stage III CC, has improved prognosis in this stage, but questions on their usefulness in high-risk stage II or elderly CC patients and on the role of some prognostic biomarkers are still pending. In April 2010, a consensus meeting on adjuvant CC treatment based on a revision of the most recent literature was held in Spain. The panel considered the use of adjuvant chemotherapy for high-risk stage II CC patients to be justifi ed. Additionally, the more convenient administration of oral fl uoropyrimidines vs. IV continuous infusion 5-FU would make XELOX a more suitable alternative for the patient. A more cautious decision should be taken when prescribing oxaliplatin treatment in patients aged 70.

Thirty patients with stage III B/IV NSCLC were treated with a combination of GIP. Patients received gemcitabine 1,000 mg/m2 administered intravenously on days 1 and 8, ifosfamide 3,500 mg/m2 on day 2, and cisplatin 80 mg/m2 on day 2, repeated every 21 days. Two of the 30 patients (7%) showed a complete response and 14 patients (46%) showed a partial response. The overall response rate was 53%. The estimated median survival for all patients was 60 weeks. All patients enrolled onto the study were eligible for toxicity assessment. Toxicities were treatable and included World Health Organization grade III or IV leukopenia (29%), thrombocytopenia (18%), anemia (7%) and nausea, and vomiting (6%). Febrile neutropenia occurred in 3 of 30 patients. There were no treatment-related deaths. The combination therapy of GIP is active, well tolerated, and easy to administer on an outpatient basis in advanced NSCLC.

Research paper thumbnail of The Medical Oncology resident mentor: situation and workload

The current situation and opinion regarding the activity of MO resident mentors was analyzed by reviewing the standing national and autonomic community regulations and via an online survey targeting mentors, residents, and physicians who are not MO mentors. The project was supervised by a specially designated group that agreed on a proposal containing recommendations for improvement. Of the MO mentors, 90% stated that they did not have enough time to perform their mentoring duties. An estimated 172 h/year on average was dedicated to mentoring, which represents 10.1% of the total time. MO mentors dedicate an average of 6.9 ...

Thanks to treatment advances, not only are more seniors diagnosed with cancer, but there are also more and more older cancer survivors. This upward trend will continue. Given the heterogeneity of aging, managing older patients with cancer poses a significant challenge for Medical Oncology. In Spain, a Geriatric Oncology Task Force has been set up within the framework of the Spanish Society for Medical Oncology (SEOM). With the aim of generating evidence and raising awareness, as well as helping medical oncologists in their training with respect to seniors with cancer, we have put together a series of basic management recommendations for this population. Many of the patients who are assessed in routine clinical practice in Oncology are older. CGA is the basic tool by means of which to evaluate older people with cancer and to understand their needs. Training and the correct use of recommendations regarding treatment for comorbidities and geriatric syndromes, support care, and drug-drug interactions and toxicities, including those of antineoplastic agents, as detailed in this article, will ensure that this population is properly managed.

The Spanish Society of Medical Oncology (SEOM) created a Working group dedicated to geriatric oncology in February 2016. The main goal of this study was to describe the current situation in Spain regarding the management of elderly cancer patients through an online survey of medical oncologists. A descriptive survey was sent to several hospitals by means of the SEOM website. A personal e-mail was also sent to SEOM members. Between March 2016 and April 2017, 154 answers were collected. Only 74 centers (48%) had a geriatrics department and a mere 21 (14%) medical oncology departments had a person dedicated to GO. The vast majority (n = 135; 88%) had the perception that the number of elderly patients with cancer seen in clinical practice had increased. Eighteen (12%) oncologists had specific protocols and geriatric scales were used at 55 (31%) centers. Almost all (92%) claimed to app...

Research paper thumbnail of New clinical trials regulation in Spain: analysis of royal decree 1090/2015

However, it led to a disproportionate increase in the bureaucratization, and thus, it became evident that procedures needed to be simplified without detriment to patient's safety. Thus, Regulation 536/2014, that repealed Directive 2001/20/EC, with the aim of decreasing the growing bureaucratization and stimulating clinical research in Europe, established simplified procedures, such as regulating a common procedure for authorising trials in Europe, the institution of strict assessment timelines, or the definition of new concepts, such as "low-intervention clinical trial". The legal form of a Regulation allowed the norm to be directly applied to Member States without the need for transposition. By means of the new Royal Decree, the national l...
