AI Article Synopsis
- The study evaluates outcomes for patients with advanced lung cancer receiving palliative radiotherapy at the Fast Track Lung Clinic, focusing on treatment responses and survival factors.
- Among 558 patients, a significant 70% showed treatment response, with higher rates linked to better performance status and specific genetic mutations, while those treated for neurological symptoms had lower responses.
- Key factors affecting overall survival included age, performance status, smoking habits, and the presence of metastases, highlighting the complexity of managing advanced lung cancer.
Article Abstract
Background: There is considerable variability in the management of patients with advanced lung cancer referred for palliative radiotherapy owing to uncertainties in prognosis and the benefit of treatment. This study presents the outcomes of patients seen in the Fast Track Lung Clinic, an urgent access palliative radiotherapy clinic, and aims to identify factors associated with treatment response and survival.
Methods: Consecutive patients with advanced lung cancer seen in the Fast Track Lung Clinic between January 2014 and July 2020 were included. Patients who underwent radiotherapy were contacted beginning 30 days after radiotherapy to evaluate treatment response. Cluster bootstraps were used to compute confidence intervals for treatment response rate. Prognostic factors for treatment response and overall survival were identified using multivariable generalized estimating equations and Cox regression models, respectively.
Results: A total of 558 patients were included, of whom 459 (82.3%) consented to palliative radiotherapy for 1053 indications. The overall treatment response rate was 70.0% (95% CI, 65.8-74.2) for indications with follow-up (70.8%). Higher response rates were observed in patients with better ECOG performance status (OR per point, 0.71; 95% CI, 0.55-0.93; ) and EGFR-mutant non-small cell lung cancer (OR vs wild-type, 2.46; 95% CI, 1.35-4.51; ), whereas patients treated for neurological symptoms had lower response rates (OR, 0.27; 95% CI, 0.16-0.45; ). There was no difference in response rate between patients who died within 30 days of starting radiotherapy and those who survived longer (OR, 0.83; 95% CI, 0.42-1.67; ). Age; ECOG performance status; smoking history; pathology; EGFR or ALK mutation status; and the presence of liver, adrenal, or brain metastases were associated with overall survival.
Conclusions: Palliative radiotherapy was effective for patients with advanced lung cancer, although response rates varied by patient characteristics and treatment indication. This study identified prognostic factors for radiotherapy response and overall survival that can inform treatment decisions in this population.

Background: Palliative sedation refers to the proportional use of titrated medication which reduces consciousness with the aim of relieving refractory suffering related to physical and psychological symptoms and/or existential distress near the end of life. Palliative sedation is intended to be an end of life option that enables healthcare professionals to provide good patient care but there remains controversy on how it is used. Little is known about decision-making processes regarding this procedure.

Background: Many patients with head and neck cancer are not candidates for standard of care definitive treatments though often require palliative treatments given the frequent symptoms associated with head and neck cancer. While existing palliative radiotherapy regimens can provide adequate symptom control, they have limitations particularly with respect to local control which is becoming more important as advances in systemic therapy are improving survival. Personalized ultrafractionated stereotactic adaptive radiotherapy (PULSAR) is a novel radiotherapy regimen which leverages advances in radiotherapy treatment technology and extended interfraction intervals to enable adaptive radiotherapy and possible synergy with the immune system.

Introduction: Anorectal melanoma (AM) is a rare and aggressive type of cancer. Its symptoms often resemble those of common benign anal conditions, such as hemorrhoids, leading to frequent delays in diagnosis. Consequently, about one-third of patients have metastases at the time of their initial diagnosis.
