    Abstract Chest wall injury is a common complication of cardiopulmonary resuscitation. Chest wall fixation of flail chest has been shown to improve outcomes in patients in whom trauma is the primary pathology. Its efficacy in the post-cardiopulmonary resuscitation setting where the primary event is cardiac arrest is yet to be determined. We report outcomes in a series of 4 patients who underwent rib fixation in the setting of cardiopulmonary resuscitation-induced flail chest.

    Abstract Objective: The optimal duration of thromboprophylaxis in patients undergoing resection of primary lung cancer is not known. We investigated the incidence of pulmonary emboli and venous thromboembolism in patients undergoing early-stage lung cancer resection and the impact of change from short duration to extended thromboprophylaxis.
    Methods: We reviewed the outcomes of consecutive patients who underwent resection of early-stage primary lung cancer following a change in protocol from inpatient-only to extended thromboprophylaxis to 28 days. Propensity-score matching of control (routine inpatient pharmacologic thromboprophylaxis) and treatment group (extended pharmacologic thromboprophylaxis) was performed. Adjustment for covariates based on the Caprini risk assessment model was undertaken. Thromboembolic outcomes were compared between the 2 groups.
    Results: Seven hundred fifty consecutive patients underwent resection of primary lung cancer at Oxford University Hospitals NHS Foundation Trust between January 2013 and December 2018. Six hundred patients were included for analysis and propensity-score matching resulted in 253 matched pairs. Extended prophylaxis was associated with a significant reduction in pulmonary emboli (10 of 253 patients [4%] vs 1 of 253 patients [0.4%], P = .01). One patient (0.4%) developed a bleeding complication within the treatment cohort. Multivariable logistic regression model demonstrated that extended thromboprophylaxis was independently associated with a reduction in postoperative pulmonary emboli.
    Conclusions: Patients undergoing lung cancer resection surgery are at moderate-to-high risk of postoperative thromboembolic disease. Extended dalteparin for 28 days is safe and is associated with reduced incidence of pulmonary embolus in patients undergoing resection of early-stage primary lung cancer.

    Abstract Objectives: The optimal imaging programme for the follow-up of patients who have undergone resection of primary lung cancer is yet to be determined. We investigated the incidence and patterns of new and recurrent malignancy after resection for early-stage lung cancer in patients enrolled into a computed tomography (CT) follow-up programme.
    Methods: We reviewed the outcomes of consecutive patients who underwent CT follow-up after resection of early-stage primary lung cancer at the Oxford University Hospitals NHS Foundation Trust, between 2013 and 2017.
    Results: Four hundred and sixty-six consecutive patients underwent resection of primary lung cancer between 1 January 2013 and 31 March 2017. Three hundred and thirty-one patients (71.0%) were enrolled in CT follow-up. The median follow-up was 98 weeks (range 26-262). Sixty patients (18.2%) were diagnosed with programme-detected malignancy. Recurrence was diagnosed in 36 patients (10.9%), new primary lung cancer in 16 patients (4.8%) and non-lung primary tumours in 8 patients (2.4%). A routine CT scan identified the majority of new primary lung cancers (84.2%) and those with disease recurrence (85.7%). The majority of programme-detected malignancies were radically treatable (55%). The median survival of programme-detected cancers was 92.4 versus 23.0 weeks for patients with clinically detected tumours (P < 0.0001). Utilizing the CT scout image as a surrogate for chest X-ray, the sensitivity of this modality was 16.95% (8.44-28.97%) and specificity was 89.83% (79.17-96.18%). Negative likelihood ratio was 0.92 (0.8-1.07).
    Conclusions: CT follow-up of surgically treated primary lung cancer patients identifies malignancy at a stage where radical treatment is possible in the majority of patients. Chest X-ray follow-up may not be of benefit following lung cancer resection.

    Abstract Background: The optimal resection rate for institutions managing early-stage primary lung cancer is not known. Whether the prognosis of patients who do not proceed to operation is determined by their comorbidities for which they were deemed at prohibitively high-operative risk, or disease progression, is uncertain. We investigated the outcomes of patients with early-stage lung cancer who were considered for surgical management.
    Methods: We reviewed the outcomes of consecutive patients who were considered for resection of early-stage primary lung cancer at Oxford University Hospitals National Health Service Foundation Trust between 2012 and 2017.
    Results: Between 29 November 2012 and 31 March 2017, 467 consecutive patients underwent resection with curative intent for primary lung cancer (operative group), while 81 patients were deemed resectable but either inoperable or did not wish to proceed to operation (non-operative group). Reason for not proceeding to resection was cardiovascular in 16 patients (19.8%), respiratory in 21 (25.9%), cardiorespiratory in 11 (13.6%), performance status in 8 (9.9%) and patient choice in 25 (30.9%) patients. Sixty-six patients (81.5%) received an alternative radical treatment. Median follow-up was 169 weeks (IQR 119-246 weeks) in the operative group and 118 weeks (IQR 74-167 weeks) in the non-operative group. Median survival of patients with early-stage lung cancer who did not proceed to operation was 2.5 years; median survival of patients undergoing lung cancer resection was undefined (p<0.0001). Lung cancer was documented as directly or indirectly leading to or contributing to death in 40 patients (76.9%). In 11 patients, the cause of death was due to comorbidities (21.2%).
    Conclusions: Patients turned down for operation in a high-resection rate UK unit have limited survival due to lung cancer progression. We conclude that 'optimal' resection rates may not have been reached in the UK even in high-resection rate centres.

    Abstract Aims and objectives: To explore patients' and healthcare professionals' views and experiences of a pre- and post-operative rehabilitation intervention (SOLACE), for patients undergoing surgery for early-stage lung cancer.
    Background: Considerable post-operative complications can occur after surgery. A specialist lung cancer service (SOLACE) was developed to optimise health and fitness levels prior to and following lung cancer resections, as well as reducing morbidity and mortality, and improving the physical and psychological well-being of patients.
    Design: The design was an exploratory, descriptive qualitative interview study.
    Methods: Seventeen lung cancer patients and eight healthcare professionals were recruited from a large teaching hospital in South England. Data were collected through semi-structured telephone and face-to-face interviews. Transcribed interview data were analysed thematically. The COREQ checklist was used to report on the study process.
    Results: The SOLACE service was positively perceived by patients and healthcare professionals. Patients valued the provision of tailored support/advice and peer support and reported benefits to their health and well-being. Barriers to patient uptake of the classes included time constraints, motivation and access for patients who lived at a distance.
    Conclusions: There is benefit in providing a personalised approach through a pre- and post-operative rehabilitation service for lung cancer patients. Virtual support may address equality of access to service for those who live at a distance from the hospital.
    Relevance to clinical practice: Introduction of a pre- and post-operative rehabilitation service provided by specialist peri-operative rehabilitation nurses and practitioners can yield positive outcomes for patients undergoing surgical treatment of early-stage lung cancer. Engagement of key healthcare professionals, consideration of virtual follow-up services and making patients aware of services could maximise patient uptake. Further consideration is needed of the best way to promote patient self-management and long-term continuation of patient rehabilitation in the community.

    Abstract Chemotherapy-induced peripheral neuropathy (CIPN) is a common, debilitating, and dose-limiting side effect of many chemotherapy regimens yet has limited treatments due to incomplete knowledge of its pathophysiology. Research on the pathophysiology of CIPN has focused on peripheral nerves because CIPN symptoms are felt in the hands and feet. However, better understanding the role of the brain in CIPN may accelerate understanding, diagnosing, and treating CIPN. The goals of this review are to (1) investigate the role of the brain in CIPN, and (2) use this knowledge to inform future research and treatment of CIPN. We identified 16 papers using brain interventions in animal models of CIPN and five papers using brain imaging in humans or monkeys with CIPN. These studies suggest that CIPN is partly caused by (1) brain hyperactivity, (2) reduced GABAergic inhibition, (3) neuroinflammation, and (4) overactivation of GPCR/MAPK pathways. These four features were observed in several brain regions including the thalamus, periaqueductal gray, anterior cingulate cortex, somatosensory cortex, and insula. We discuss how to leverage this knowledge for future preclinical research, clinical research, and brain-based treatments for CIPN.

    Abstract Purpose: Patients with cancer frequently undergo research-grade germline sequencing but clinically actionable results are not routinely disclosed. The objective of this study is to evaluate the feasibility of reporting clinically relevant secondary findings (SF) identified in germline research sequencing using the institutional molecular tumor board (MTB) and the treating oncology physician.
    Methods: This prospective, interventional cohort study enrolled Total Cancer Care participants with any cancer diagnosis at a single institution. Patients underwent research-grade germline whole-exome sequencing, with bioinformatic analysis in a Clinical Laboratory Improvement Amendments-certified laboratory to verify pathogenic/likely pathogenic germline variants (PGVs) in any American College of Medical Genomics and Genetics SF v2.0 genes. After a protocol modification in consenting patients, the MTB reported PGVs to treating oncology physicians with recommendations for referral to a licensed genetic counselor and clinical confirmatory testing.
    Results: Of the 781 enrolled participants, 32 (4.1%) harbored cancer predisposition PGVs, 24 (3.1%) were heterozygous carriers of an autosomal recessive cancer predisposition syndrome, and 14 (1.8%) had other hereditary disease PGVs. Guideline-directed testing would have missed 37.5% (12/32) of the inherited cancer predisposition PGVs, which included
    Conclusion: MTB reporting of research-grade germline sequencing to the clinical oncology team is feasible. Over a third of PGVs identified using a universal testing strategy would have been missed by guideline-based approach, suggesting a role for expanding germline testing.
