Real-World Treatment Patterns and Survival Outcomes for Patients with Non-Metastatic Non-Small-Cell Lung Cancer in Sweden: A Nationwide Registry Analysis from the I-O Optimise Initiative.

Non-small-cell lung cancer (NSCLC) is the leading cause of cancer-related death worldwide, with ~40-50% of patients diagnosed with non-metastatic disease (stages IA-IIIC). The treatment landscape is evolving rapidly as immunotherapies and targeted therapy are introduced in the non-metastatic setting, creating a need to assess patient outcomes prior to their introduction. This real-world study using Swedish National Lung Cancer Registry data examined outcomes (overall survival (OS) and time to next treatment or death (TTNTD)) and treatment patterns for adults diagnosed with non-metastatic NSCLC. Baseline characteristics and OS from diagnosis were described for all patients; OS, treatment patterns, and TTNTD from treatment start were described for the treatment subgroup (patients diagnosed from 2014 onwards), stratified by disease stage and initial treatment. OS and TTNTD were described using the Kaplan-Meier estimator. The overall population (2008-2019) included 17,433 patients; the treatment subgroup included 5147 patients. Median OS (interquartile range) overall ranged from 83.3 (31.6-165.3) months (stage I patients) to 10.4 (4.3-24.2) months (stage IIIB patients). Among the treatment subgroup, median OS and TTNTD were longest among patients receiving surgery versus other anticancer treatments. These findings provide a baseline upon which to evaluate the epidemiology of non-metastatic NSCLC as newer treatments are introduced.

Community prescribing for cancer patients at the end of life: a national study.

BACKGROUND: Good end-of-life care is essential to ensure dignity and comfort in death. To our knowledge, there has not been a national population-based study in England of community prescribing of all drugs used in end-of-life care for patients with cancer. METHODS: 57 632 people who died from malignant cancer in their own home or in a care home in 2017 in England were included in this study. National routinely collected data were used to examine community prescriptions dispensed for drugs for symptom control and anticipatory prescribing by key sociodemographic factors in the last 4 months of life. RESULTS: 94% of people who died received drugs to control their symptoms and 65% received anticipatory prescribing. Prescribing increased for the symptom control drug group (53% to 75%) and the anticipatory prescribing group (4% to 52%) over the 4-month period to death. CONCLUSIONS: Most individuals who died of cancer in their own home or a care home were dispensed drugs commonly used to control symptoms at the end of life, as recommended by best-practice guidance. Lower prescribing activity was found for those who died in a care home, highlighting a potential need for improved end-of-life service planning.

Longitudinal trends of peripheral blood counts in polycythaemia vera and essential thrombocythemia patients in the UK.

There is sparse evidence of how well haematological targets are met in practice for essential thrombocythemia (ET) and polycythaemia vera (PV) patients. Patient data was collected between 2008 and 2020 from two UK NHS Trusts for ET and PV patients. Longitudinal changes in peripheral blood counts, including the proportion of patients meeting peripheral blood count remission, was modelled. Relative risk of cardiovascular-related events for patients achieving remission within 3-months was estimated. A total of 620 ET and 429 PV patients were analysed. For high-risk patients, haematological parameters decreased in the first months of observation then stabilised within normal reference ranges until year 5. Total time spent in peripheral blood count remission was 39.2% for ET and 29.1% for PV. A lower proportion of ET patients reached target platelet counts (48.3%) compared to WBC (79.1%), whilst PV patients were less likely to reach target haematocrit levels (56.9%) compared to platelets (77.3%) or WBC (74.6%). There was no statistically significant association between reaching target blood counts within 3-months and cardiovascular risk. Complete haematological remission remains a challenging target in managing PV and ET, however this study was unable to show statistically-significant evidence that this was associated with increased risk of cardiovascular events.

Endocrine therapy in the years following a diagnosis of breast cancer: A proof of concept study using the primary care prescription database linked to cancer registration data.

INTRODUCTION: National cancer registration data were linked to the Primary Care Prescription Database (PCPD) in England. The level of endocrine therapy (ET) prescribed in women after a diagnosis of breast cancer was studied. MATERIALS AND METHODS: Cancer registrations for women diagnosed with breast cancer during 1995-2015, who survived to 31st March 2015, were linked to ET prescriptions issued during April-July 2015. RESULTS: Among 369 277 survivors of breast cancer diagnosed during 1995-2015, 37% were prescribed ET during April-July 2015. Among women whose breast cancer diagnosis was after 31st July 2010, 81% of those recorded with oestrogen receptor positive (ER+ve) disease were prescribed ET compared with only 6% of those with ER-ve disease. Younger women usually received tamoxifen and older women usually received aromatase inhibitors. DISCUSSION: The pattern of ET use observed in these data corresponds to that expected. This provides confidence in the potential of the PCPD for epidemiological research.
