Breast radiotherapy in elderly women: myths, controversies, and current techniques in the adjuvant setting

In developed countries, breast cancer (BC) is the most common type of cancer in women, mainly affecting patients over age 60. Due to the increasing life expectancy and population ageing, the incidence of BC is expected to increase significantly in the coming years. However, no standardized clinical guidelines are available to assist in decision-making in elderly patients. Moreover, there is a lack of quality scientific evidence to guide treatment selection in this patient population, who are underrepresented in clinical trials. Consequently, up to 50% of elderly women are treated suboptimally, which implies a worse prognosis and survival. Given that the current estimated life expectancy of a healthy 70-year-old woman is 15 years, any treatment capable of reducing the likelihood of disease recurrence and cancer-specific mortality in this patient population would be beneficial. Adjuvant radiotherapy (RT) is one of the pillars of treatment for BC and it plays a key role in improving local control (LC) and overall survival (OS). Adjuvant RT is clearly indicated in young patients who undergo breast-conserving surgery (BCS) as well as in high risk patients, regardless of age. However, the use of adjuvant RT in older patients with early-stage disease has decreased in recent years—even in patients who undergo BCS—due to outdated concerns about the possible side effects of RT and reports suggesting that RT can be omitted in low-risk patients. One of the greatest challenges currently facing radiation oncologists who specialise in the treatment of BC is the selection of elderly patients who are likely to benefit from adjuvant RT. There is also a clear need to critically evaluate the available evidence and to apply those findings to routine clinical practice. Given this context, the aim of the present review is to clarify the current role of adjuvant RT in the management of BC in older women—particularly those with early-stage disease—and to dispel the myths surrounding the use of RT to treat elderly women. This review primarily focuses on the indications, controversies, and irradiation techniques used in this patient subgroup.Sin financiación1.241 JCR (2020) Q4, 233/242 Oncology0.254 SJR (2020) Q4, 183/211 Cancer ResearchNo data IDR 2020UE

Management of oligometastatic non-small cell lung cancer patients: Current controversies and future directions

Oligometastatic non-small cell lung cancer (NSCLC) describes an intermediate stage of NSCLC between localized and widely-disseminated disease. This stage of NSCLC is characterized by a limited number of metastases and a more indolent tumor biology. Currently, the management of oligometastatic NSCLC involves radical treatment (radiotherapy or surgery) that targets the metastatic lesions and the primary tumor to achieve disease control. This approach offers the potential to achieve prolonged survival in patients who, in the past, would have only received palliative measures. The optimal therapeutic strategies for the different scenarios of oligometastatic disease (intracranial vs extracranial disease, synchronous vs metachronous) remain undefined. Given the lack of head-to-head studies comparing radiotherapy to surgery in these patients, the decision to apply surgery or radiotherapy (with or without systemic treatment) must be based on prognostic factors that allow us to classify patients. This classification will allow us to select the most appropriate therapeutic strategy on an individualized basis. In the future, the molecular or microRNA profiles will likely improve the treatment selection process. The objective of the present article is to review the most relevant scientific evidence on the management of patients with oligometastatic NSCLC, focusing on the role of radiotherapy and surgery. We also discuss areas of controversy and future directions.Sin financiaciónNo data 2019UE

Advances in multimodal treatment for stage IIIA-N2 non-small cell lung cancer

Background and aim: In stage IIIA-N2 non-small cell lung cancer (NSCLC), the accuracy of combined positron-emission tomography/computed tomography imaging (PET-CT), together with mediastinal staging techniques, has led to a wide range of challenging clinical scenarios in terms of therapeutic management. Concurrent chemoradiotherapy followed by consolidation immunotherapy remains the standard of care. In patients with potentially-resectable disease, surgery plays an important role in multimodal therapy. The introduction of targeted therapies and immune-checkpoint inhibitors have revolutionized multimodal treatment. In the present article, we review current treatment options and future trends in stage IIIA-N2 NSCLC. Relevance for patients: This article provides insight into the current status of multimodal treatment for NSCLC to support decision-making in routine clinical practice.Sin financiaciónNo data 2020UE
