Prevalence and risk factors associated with readmission with acute kidney injury in patients receiving vancomycin outpatient parenteral antimicrobial therapy.
The purpose of this study was to understand barriers to early-stage lung cancer care at high-volume academic centers in the US. Researchers conducted semi-structured interviews with patients with suspected or diagnosed early-stage non-small cell lung cancer who had presented to a multidisciplinary clinic at academic institutions over a 6-month period; a qualitative content analysis was then performed using the framework method. Six themes relating to barriers and facilitators to lung-cancer care were identified, and the authors concluded that these factors must be addressed to improve quality of care among lung cancer patients.

Functional status and survival in older nursing home residents with advanced non-small-cell lung cancer: a SEER-Medicare analysis.
The purpose of this study was to examine the association between activities of daily living (ADL) impairment and overall survival in patients 65 and older with advanced non-small-cell lung cancer (NSCLC) receiving care in nursing homes from 2011 to 2015. The researchers examined the association between ADL scores and overall survival among 3,174 patients who received systemic cancer chemotherapy or immunotherapy within 3 months of NSCLC diagnosis; and among patients who did not receive any treatment. The study found that the ADL score was associated with increased risk of death. One standard deviation increase in the ADL score was associated with lower overall survival rate among treated and untreated patients The median overall survival was 3.1 months for patients with an ADL score of less than 14, 2.8 months for patients with an ADL score between 14 and 17, 2.3 months for patients with ADL score between 18-19, and 1.8 months for patients with ADL score of 20+. The researchers concluded that the ADL assessment may be a useful clinical tool in nursing home adults aged 65 and older with advanced non-small-cell lung cancer.

Inaccuracies in electronic health records smoking data and a potential approach to address resulting underestimation in determining lung cancer screening eligibility.
The authors sought to characterize EHR smoking data issues and to propose an approach to addressing these issues using longitudinal smoking data. They found that over 80% of evaluated records had inaccuracies, including missing packs-per-day or years-smoked, outdated data, missing years-quit, and a recent change in packs-per-day resulting in inaccurate lifetime pack-years estimation. Further, addressing these issues by using longitudinal data enabled the identification of 49.4% more patients potentially eligible for lung cancer screening.

Implementing lung cancer screening in primary care: needs assessment and implementation strategy design.
This study explored the implementation of lung cancer screening with low-dose computed tomography (CT) in primary care. The study’s two goals included exploring the implementation of lung cancer screening primary care in the context of integrating a decision aid into the electronic health record and a designing of implementation strategies that target hypothesized mechanics of change and context-specific barriers. The two phases included a Qualitative Analysis phase including semi-structured interviews with primary care physicians to elicit key task behaviors, and an Implementation Strategy Design phase consisting of defining implementation strategies and hypothesizing causal pathways to improve screening with a decision aid. Fourteen interviews were conducted and out of that 3 key task behaviors and four behavioral determinants emerged. Strategies included increasing provider self-efficacy toward performing shared decision making and using the decision aid, improving provider performance expectancy, increasing social influence, and addressing key facilitators to using the decision aid.

Surgically managed clinical stage iiia-clinical n2 lung cancer in the Society of Thoracic Surgeons Database.
The objective of this study was to characterize the management of clinical stage IIIA-N2 positive (cIIIA-N2) lung cancer in The Society of Thoracic Surgeons General Thoracic Surgery Database. Surgeons achieved excellent short- and long-term results treating predominantly lobectomy-amenable cIIIA-N2 lung cancer. However, prevalent overstaging and abstention from induction therapy suggested "overcoding" of false positives on imaging or variable compliance with current guidelines for cIIIA-N2 lung cancer.

Medicare beneficiaries with advanced lung cancer experience diverse patterns of care from diagnosis to death.
Using Medicare claims data for patients diagnosed with extensive-stage small-cell lung cancer, the authors used latent class analysis to identify classes of people with different care patterns. The findings showed substantial heterogeneity in patterns of care for patients with advanced cancer, which should be accounted for in efforts to improve end-of-life care.

Calibrating how doctors think and seek information to minimise errors in diagnosis.
This editorial discusses a study by Sheringham et al., published in 2017 in BMJ Quality and Safety, and entitled “Variations in GPs’ decisions to investigate suspected lung cancer: a factorial experiment using multimedia vignettes” in which they used simulated patient vignettes to understand the role that patient characteristics (including demographics and symptomatology) play in physicians’ decisions to investigate for possible diagnosis of lung cancer.

Early palliative care in advanced illness: do right by mama.
This letter describes a case study where the doctor and the family decided not to do aggressive treatment on their mother in her 80’s with metastatic lung cancer and pneumonia. After describing the intubation procedure and the use of mechanical ventilation, the family decided that palliative care was the best option. The doctor emphasizes the use of palliative care as the best outcome for many terminally ill patients.

Repurposing ospemifene for potentiating an antigen-specific immune response.
The overall objective of the present series of preclinical studies was to evaluate the immunomodulatory activity of ospemifene in combination with a peptide cancer vaccine. The authors concluded that, taken together, ospemifene's dose response and schedule-dependent immune modulating activity offers a method of tailoring and augmenting the efficacy of previously failed antigen-specific cancer vaccines for a wide range of malignancies.

Revisiting a longstanding clinical trial exclusion criterion: impact of prior cancer in early-stage lung cancer.
The researchers examined the prevalence and prognostic impact of a prior cancer diagnosis among patients with early-stage lung cancer. They found no difference in all-cause survival between patients with and without prior cancer. Lung cancer specific survival was improved among patients with prior cancer.

Survival gains from first-line systemic therapy in metastatic non-small cell lung cancer in the U.S., 1990-2015: progress and opportunities.
The objectives of this study were to quantify survival gains from 1990, when best supportive care only was standard, to 2015 and to estimate the impact of expanded use of new systemic therapies in clinically appropriate patients. By using simulation modeling to quantify metastatic non-small cell lung cancer survival gains from 1990-2015, the researchers estimated that the one-year survival proportion and mean per-patient survival increased by 14.1 percent and 4.2 months, respectively.

A method to reconstruct and apply 3D primary fluence for treatment delivery verification.
In this study, a method is reported to perform IMRT and VMAT treatment delivery verification using 3D volumetric primary beam fluences reconstructed directly from planned beam parameters and treatment delivery records. The goals of this paper are to demonstrate that 1) 3D beam fluences can be reconstructed efficiently, and 2) quality assurance (QA) based on the reconstructed 3D fluences is capable of detecting additional treatment delivery errors, particularly for VMAT plans.
