The general population is aging, which expectedly will lead to a future increase in older patients with cancer. This review summarises the recent advances in radiotherapy. Technological advances have led radiotherapy to be an efficient and well-tolerated treatment option in older patient with cancer.

Radiotherapy may further increase this risk. We aim to investigate the impact of stereotactic body radiotherapy (SBRT) on thrombin generation and platelet aggregation.

View Article and Find Full Text PDFPatients with lung cancer face a substantially increased risk of thromboembolic disease. Patients with localized non-small cell lung cancer (NSCLC) who are unfit for surgery due to age or comorbidity have additional thrombotic risk factors. Thus, we aimed to investigate markers of primary and secondary hemostasis, since this could assist in treatment decisions.

The current study aims to externally evaluate this observation within a patient cohort treated using daily IGRT.
Method: NSCLC patients with locally-advanced disease and daily CBCT were included.
Background: This open-label Phase III trial (NCT02264990) evaluated the PARP inhibitor, veliparib, combined with carboplatin/paclitaxel versus chemotherapy alone for first-line treatment of patients with advanced non-squamous non-small cell lung cancers (NSCLC). A 52-gene expression classifier (LP52) previously shown to identify patients more likely to respond to veliparib was evaluated as a planned correlative analysis.
Materials And Methods: Adult current or former smokers with advanced non-squamous NSCLC were randomized 1:1 to veliparib (120 mg daily for 7 days/cycle) with carboplatin and paclitaxel or to investigators' choice of platinum doublet chemotherapy (up to 6, 21-day cycles), with optional pemetrexed maintenance.
Background And Purpose: With daily, MR-guided online adapted radiotherapy (MRgART) it may be possible to reduce the PTV in pelvic RT. This study investigated the potential reduction in normal tissue complication probability (NTCP) of MRgART compared to standard radiotherapy for high-risk prostate cancer.
Materials And Methods: Twenty patients treated with 78 Gy to the prostate and 56 Gy to elective pelvic lymph nodes were included.
Background: The aim is to quantify and analyse tumour motion during a course of treatment for lung SBRT patients.
Material And Methods: Peak-to-peak motion of 483 tumours in 441 patients treated with peripheral lung SBRT at a single institution over a two year period was measured on planning CT and at all treatment fractions. Planning 4D-CT scans were analysed using our clinical workflow involving deformable propagation of the delineated target to all phases.
About half of all Danish cancer patients are 70 years or older at diagnosis. The incidence is expected to increase further over the coming years because of an increasing longevity. Therefore, this review recommends that the Danish health care system develops and implement models to ensure optimal care for older adults with cancer.

However, the role of PCI is debated in the modern era of increased brain magnetic resonance imaging (MRI) availability. BM in SCLC patients may respond to chemotherapy, and if a negative MRI is used in the decision to use of PCI in the treatment strategy, the timing of brain MRI may be crucial when evaluating the effect of PCI.

This phenomenological hermeneutic study included nine patients, eight family caregivers, and 11 nurses. Data were collected using participant observation, informal and semi-structured individual or joint interviews with patients and family caregivers, and focus group interviews with nurses.

This study aimed to assess if the G-8 combined with a hand-grip strength test (HGST) in patients with NSCLC treated with stereotactic body radiotherapy can predict long-term OS better than the G-8 alone. A total of 46 SBRT-treated patients with NSCLC of stage T1-T2N0M0 were included.

This study investigates the evolution of the tumour extent and evaluates the need for plan adaptation to ensure dose coverage of the target in glioblastoma patients.
Materials And Methods: The prospective study included 29 patients referred for 59.
Background And Purpose: Deformable image registration (DIR) and contour propagation are used in daily online adaptation for hybrid MRI linac (MRL) treatments. The accuracy of the propagated contours may vary depending on the chosen workflow (WF), affecting the amount of required manual corrections. This study investigated the impact of three different WFs of contour propagations produced by a clinical treatment planning system for a high-field MRL on head and neck cancer patients.
View Article and Find Full Text PDFBackground: When discussing treatment options and future care, it is important to understand the expectations of patients and family caregivers related to palliative chemotherapy and to identify patterns in patients' quality of life. The study aims were to evaluate differences in treatment expectations and quality of life between patients with thoracic cancer (non-small-cell lung cancer, small-cell lung cancer and mesothelioma) who were < 70 and ≥ 70 years of age and receiving palliative chemotherapy and to assess family caregivers' treatment expectations.
Methods: A prospective longitudinal study included patients with thoracic cancer receiving outpatient palliative chemotherapy at a university hospital in Denmark and their family caregivers.
Purpose: Prospectively scored radiation pneumonitis (RP) observed in a national, randomized phase II dose-escalation trial for patients with locally advanced non-small cell lung cancer (NSCLC) was investigated.
Methods: Patients with stage IIB-IIIB histologically proven NSCLC were treated with concomitant chemo-radiotherapy (oral Vinorelbine 3times/week) at 60 Gy/30fx (A-59pts) and 66 Gy/33fx (B-58pts) from 2009 to 2013 at five Danish RT centers. Grade 2 RP (CTCAEv3.
Purpose: In the Rehabilitation of Prostate Cancer (RePCa) study, the intervention reduced early adverse effects in prostate cancer 6 months after radiotherapy. This 3-year follow-up study assesses late adverse effects, evaluates rehabilitative long-term effects and identifies patients who benefit the most.
Design: RePCa was a randomized clinical trial with multidisciplinary rehabilitation (n = 79) or usual care (n = 82).
Background: In this study we have evaluated the accuracy of automatic, deformable structure propagation from planning CT and MR scans for daily online plan adaptation for MR linac (MRL) treatment, which is an important element to minimize re-planning time and reduce the risk of misrepresenting the target due to this time pressure.
Methods: For 12 high-risk prostate cancer patients treated to the prostate and pelvic lymph nodes, target structures and organs at risk were delineated on both planning MR and CT scans and propagated using deformable registration to three T2 weighted MR scans acquired during the treatment course. Generated structures were evaluated against manual delineations on the repeated scans using intra-observer variation obtained on the planning MR as ground truth.
Background: Patients with metastatic spinal cord compression (MSCC) and favorable survival prognoses can benefit from radiation doses greater than 30Gy in 10 fractions in terms of improved local progression-free survival (LPFS) and overall survival (OS).
Methods/design: This prospective study mainly investigates LPFS after precision radiotherapy (volumetric modulated arc therapy or stereotactic body radiotherapy) with 18 × 2.33Gy in 3.
Patients with small cell lung cancer (SCLC) with poor performance status (PS) especially in the elderly may not benefit from chemotherapy. The aim of this study was to compare survival of treated patients with PS 3-4 with untreated patients. We reviewed the medical records and pathology data for 448 patients diagnosed with small cell carcinoma from 2010 to 2015 and selected all patients in PS 3-4 for review.
