Developing an Integrated Service Planning Tool: Lessons Learnt from Planning the WSLHD Thoracic Oncology Program

Aim

We aim to provide practical guidelines on how to develop integrated service plans that incorporate care provided by multiple specialties.

Introduction

Bringing specialties together to strategically plan future health service delivery is challenging. In Australia, collaboration between specialties is required to prepare for the introduction of the National Lung Cancer Screening Program (NLCSP). The purpose of this investigation is to provide practical guidelines on how to develop integrated service plans that incorporate care provided by multiple specialties.

Description

Collaborative planning was undertaken in Western Sydney Local Health District (WSLHD) to develop a WSLHD Thoracic Oncology Program Service Plan. The planning process included oversite by a steering committee, engagement of a range of stakeholders, a series of interviews, meetings and workshops, and the documentation of the strategies and actions required to implement the plan. The planning process was analysed to produce an Integrated Service Planning Tool (ISPT).

Discussion

The ISPT includes five key enablers for the planning process: foster a strong culture of collaboration; establish strategic governance; identify a patient journey framework; conduct extensive and flexible stakeholder consultation; and formalise the plan with documentation of a roadmap. Key actions for each enabler translate the ideas into activities.

Conclusion

A culture of collaboration across specialties supports the development of an integrated service plan that encompasses the full patient journey. The ISPT provides a blueprint for overcoming a traditional siloed approach to service planning for diseases and conditions that require interdisciplinary care.

Advancements in lung cancer: a comprehensive perspective on diagnosis, staging, therapy and follow-up from the SAKK Working Group on Imaging in Diagnosis and Therapy Monitoring

In 2015, around 4400 individuals received a diagnosis of lung cancer, and Switzerland recorded approximately 3200 deaths related to lung cancer. Advances in detection, such as lung cancer screening and improved treatments, have led to increased identification of early-stage lung cancer and higher chances of long-term survival. This progress has introduced new considerations in imaging, emphasising non-invasive diagnosis and characterisation techniques like radiomics. Treatment aspects, such as preoperative assessment and the implementation of immune response evaluation criteria in solid tumours (iRECIST), have also seen advancements. For those undergoing curative treatment for lung cancer, guidelines propose follow-up with computed tomography (CT) scans within a specific timeframe. However, discrepancies exist in published guidelines, and there is a lack of universally accepted recommendations for follow-up procedures. This white paper aims to provide a certain standard regarding the use of imaging on the diagnosis, staging, treatment and follow-up of patients with lung cancer.

Molecular Diagnostic Yield and Safety Profile of Ultrasound-Guided Lung Biopsies: A Cross-Sectional Study

BACKGROUND

The recent advances in precision oncology for lung cancer treatment has focused attention on the importance of obtaining appropriate specimens for tissue diagnosis as well as comprehensive molecular profiling. CT scan-guided biopsies and bronchoscopy are currently the main procedures employed for tissue sampling. However, growing evidence suggests that ultrasound-guided biopsies may represent an effective as well as safe approach in this diagnostic area. This study explores the safety and the diagnostic yield for cancer molecular profiling in ultrasound-guided percutaneous lung lesion biopsies (US-PLLB).

METHODS

One hundred consecutive patients with suspected lung cancer, between January 2021 and May 2024, who had ultrasound-guided lung biopsies have been retrospectively analyzed. Molecular profiling was conducted with next-generation sequencing Genexus using Oncomine precision assay or polymerase chain reaction according to specimen quality. Qualitative immunohistochemical assay of programmed death ligand 1 (PD-L1) expression was evaluated by the Dako PD-L1 immunohistochemistry 22C3 pharmDx assay. The co-primary endpoints were the molecular diagnostic yield and the safety profile of US-guided lung biopsies.

RESULTS

From January 2021 to May 2024, 100 US-guided lung biopsies were carried out and 95 were considered for inclusion in the study. US-PLLB provided informative tissue for a histological evaluation in 93 of 95 patients with an overall diagnostic accuracy of 96.84% [Sensitivity: 92.63%; Specificity: 96.84%; PPV: 100%; NPV: 100%]. Sixty-Six patients were diagnosed with NSCLC (69.47%) and were considered for molecular diagnostic yield evaluation and PD-L1 testing. Four patients had malignant lymphoid lesions. US-PLLB was not adequate to achieve a final diagnosis in three patients (3.16%). Complete molecular profiling and PD-L1 evaluation were achieved in all patients with adenocarcinoma (molecular diagnostic yield: 100%). PD-L1 evaluation was achieved in 28 of 29 patients (96.55%) with either SCC or NOS lung cancer. The overall complication rate was 9.47% (n = 9). Six patients (6.31%) developed pneumothorax, while three patients (3.16%) suffered mild haemoptysis without desaturation.

CONCLUSIONS

According to our findings, US-guided lung biopsy is a safe, minimally invasive procedure in patients with suspected lung malignancies, providing an excellent diagnostic yield for both comprehensive molecular profiling and PD-L1 testing. In addition, our results suggest that US-guided biopsy may also be an effective diagnostic approach in patients with suspected lung lymphoma.

Added value of EUS-B-FNA to bronchoscopy and EBUS-TBNA in diagnosing and staging of lung cancer

Background

Bronchoscopy and EBUS are standard procedures in lung cancer work-up but have low diagnostic yield in lesions outside the central airways and hilar/mediastinal lymph nodes. Growing evidence on introducing the EBUS endoscope into the oesophagus (EUS-B) in the same session as bronchoscopy/EBUS gives access to new anatomical areas that can be safely biopsied.

Objective

To summarize the current evidence of the added value of EUS-B-FNA to bronchoscopy and EBUS-TBNA in lung cancer work-up.

Methods

A narrative review.

Results

Few randomized trials or prospective studies are available. Prospective studies show that add-on EUS-B-FNA increases diagnostic yield when sampling abnormal mediastinal lymph nodes, para-oesophageal lung and left adrenal gland. A large retrospective series on EUS-B-FNA from retroperitoneal lymph nodes suggests high diagnostic yield without safety concerns, as do casuistic reports on EUS-B-FNA from mediastinal pleural thickening, pancreatic lesions, ascites fluid and pericardial effusions. No study has systematically assessed both diagnostic yield, safety, patient reported outcomes, adverse events and costs.

Conclusion

The diagnostic value of add-on EUS-B to standard bronchoscopy and EBUS in lung cancer work-up appears very promising without safety concerns, giving the pulmonologist access to a variety of sites out of reach with other minimally invasive techniques. Little is known on patient-reported outcomes and costs. Future and prospective research should focus on effectiveness aspects to clarify whether overall benefits of add-on EUS-B sufficiently exceed overall downsides.

Inter- and intra-observer variability of radial-endobronchial ultrasound image interpretation for peripheral pulmonary lesions

Background

Radial probe endobronchial ultrasound (R-EBUS) is often utilized in guided bronchoscopy for the diagnosis of peripheral pulmonary lesions. R-EBUS probe positioning has been shown to correlate with diagnostic yield, but overall diagnostic yield with this technology has been inconsistent across the published literature. Currently there is no standardization for R-EBUS image interpretation, which may result in variability in grading concentricity of lesions and subsequently procedure performance. This was a survey-based study evaluating variability among practicing pulmonologists in R-EBUS image interpretation.

Methods

R-EBUS images from peripheral bronchoscopy cases were sent to 10 practicing Interventional Pulmonologists at two different time points (baseline and 3 months). Participants were asked to grade the images as concentric, eccentric, or no image. Cohen's Kappa-coefficient was calculated for inter- and intra-observer variability.

Results

A total of 100 R-EBUS images were included in the survey. There was 100% participation with complete survey responses from all 10 participants. Overall kappa-statistic for inter-observer variability for Survey 1 and 2 was 0.496 and 0.477 respectively. Overall kappa-statistic for intra-observer variability between the two surveys was 0.803.

Conclusions

There is significant variability between pulmonologists when characterizing R-EBUS images. However, there is strong intra-rater agreement from each participant between surveys. A standardized approach and grading system for radial EBUS patterns may improve inter-observer variability in order to optimize our clinical use and research efforts in the field.

The Interdisciplinary Management of Lung Cancer in the European Community

Lung cancer continues to be the largest cause of cancer-related mortality among men and women globally, accounting for around 27% of all cancer-related deaths. Recent advances in lung cancer medicines, particularly for non-small-cell lung cancer (NSCLC), have increased the need for multidisciplinary disease care, thereby enhancing patient outcomes and quality of life. Different studies in the European community have evaluated the impact of multidisciplinary care on outcomes for lung cancer patients, including its impact on survival, adherence to guideline treatment, utilization of all treatment modalities, timeliness of treatment, patient satisfaction, quality of life, and referral to palliative care. This publication will examine the roles and duties of all multidisciplinary members and the influence of multidisciplinary care on lung cancer outcomes in Europe. Multidisciplinary treatment is the foundation of lung cancer treatment. The optimal setting for interdisciplinary collaboration between specialists with complementary functions is multidisciplinary meetings. Multidisciplinary care in lung cancer facilitates the delivery of a high-quality service, which may improve lung cancer patients’ survival, utilization of all treatment modalities, adherence to guideline management, and quality of life, despite the fact that only limited observational data have demonstrated these results. To confirm the relationship between multidisciplinary treatment and improved lung cancer patient outcomes, however, further research is required.

Shape-Sensing Robotic-Assisted Bronchoscopy in the Diagnosis of Pulmonary Parenchymal Lesions

BACKGROUND

The landscape of guided bronchoscopy for the sampling of pulmonary parenchymal lesions is evolving rapidly. Shape-sensing robotic-assisted bronchoscopy (ssRAB) recently was introduced as means to allow successful sampling of traditionally challenging lesions.

RESEARCH QUESTION

What are the feasibility, diagnostic yield, determinants of diagnostic sampling, and safety of ssRAB in patients with pulmonary lesions?

STUDY DESIGN AND METHODS

Data from 131 consecutive ssRAB procedures performed at a US-based cancer center between October 2019 and July 2020 were captured prospectively and analyzed retrospectively. Definitions of diagnostic procedures were based on prior standards. Associations of procedure- and lesion-related factors with diagnostic yield were examined by univariate and multivariate generalized linear mixed models.

RESULTS

A total of 159 pulmonary lesions were targeted during 131 ssRAB procedures. The median lesion size was 1.8 cm, 59.1% of lesions were in the upper lobe, and 66.7% of lesions were beyond a sixth-generation airway. The navigational success rate was 98.7%. The overall diagnostic yield was 81.7%. Lesion size of ≥ 1.8 cm and central location were associated significantly with a diagnostic procedure in the univariate analysis. In the multivariate model, lesions of ≥ 1.8 cm were more likely to be diagnostic compared with lesions < 1.8 cm, after adjusting for lung centrality (OR, 12.22; 95% CI, 1.66-90.10). The sensitivity and negative predictive value of ssRAB for primary thoracic malignancies were 79.8% and 72.4%, respectively. The overall complication rate was 3.0%, and the pneumothorax rate was 1.5%.

INTERPRETATION

This study was the first to provide comprehensive evidence regarding the usefulness and diagnostic yield of ssRAB in the sampling of pulmonary parenchymal lesions. ssRAB may represent a significant advancement in the ability to access and sample successfully traditionally challenging pulmonary lesions via the bronchoscopic approach, while maintaining a superb safety profile. Lesion size seems to remain the major predictor of a diagnostic procedure.

Hospital-based multidisciplinary lung cancer care in Australia: a survey of the landscape in 2021

Introduction

Lung cancer is the leading cause of cancer death in Australia and has the highest cancer burden. Numerous reports describe variations in lung cancer care and outcomes across Australia. There are no data assessing compliance with treatment guidelines and little is known about lung cancer multidisciplinary team (MDT) infrastructure around Australia.

Methods

Clinicians from institutions treating lung cancer were invited to complete an online survey regarding the local infrastructure for lung cancer care and contemporary issues affecting lung cancer.

Results

Responses from 79 separate institutions were obtained representing 72% of all known institutions treating lung cancer in Australia. Most (93.6%) held a regular MDT meeting although recommended core membership was only achieved for 42/73 (57.5%) sites. There was no thoracic surgery representation in 17/73 (23.3%) of MDTs and surgery was less represented in regional and low case volume centres. Specialist nurses were present in just 37/79 (46.8%) of all sites. Access to diagnostic and treatment facilities was limited for some institutions. IT infrastructure was variable and most sites (69%) do not perform regular audits against guidelines. The COVID-19 pandemic has driven most sites to incorporate virtual MDT meetings, with variable impact around the country. Clinician support for a national data-driven approach to improving lung cancer care was unanimous.

Discussion

This survey demonstrates variations in infrastructure support, provision and membership of lung cancer MDTs, in particular thoracic surgery and specialist lung cancer nurses. This heterogeneity may contribute to some of the well-documented variations in lung cancer outcomes in Australia.

The clinical relevance of lymphocyte to monocyte ratio in patients with Idiopathic Pulmonary Fibrosis (IPF)

Disease course in Idiopathic Pulmonary Fibrosis (IPF) is highly heterogeneous and markers of disease progression would be helpful. Blood leukocyte count has been studied in cancer patients and a reduced lymphocyte to monocyte ratio (LMR) has been show to predict survival. Thus, we aimed to investigate the role of monocytes count and LMR in three distinct population of patients with IPF: 77 newly-diagnosed IPF, 40 with end-stage IPF and 17 IPF with lung cancer. In newly-diagnosed IPF patients, we observed a negative correlation between forced vital capacity (FVC) at diagnosis and both white blood cells and monocytes count (r = -0.24; p = 0.04 and r = -0.27; p = 0.01; respectively). Moreover, a high monocytes count was independently associated with functional decline (OR: 1.004, 95%CI 1.00-1.01; p = 0.03). In newly-diagnosed IPF, the LMR cut-off at diagnosis was 4.18 with an AUC of 0.67 (95%CI 0.5417-0.7960; p = 0.025), and overall survival was significantly worse in patients with a LMR<4.18 compared to patients with a LMR≥4.18 (HR: 6.88, 95%CI 2.55-18.5; p = 0.027). LMR was significantly lower in IPF patients with lung cancer compared to those newly diagnosed with IPF [2.2 (0.8-4.4), 3.5 (0.8-8.8); p < 0.0001] and those with end-stage disease [3.6 (2-6.5); p < 0.0001]. In conclusion, a LMR<4.18 is associated with significantly shorter survival in newly-diagnosed IPF patients. In addition, LMR is significantly lower in patients with IPF and lung cancer compared to patients with newly-diagnosed IPF. High monocytes count at baseline negatively correlates with FVC and is an independent predictor of disease progression in newly-diagnosed IPF patients.

Intraoperative Lung Ultrasound (ILU) for the Assessment of Pulmonary Nodules

Background: The primary aim of this study was to confirm the validity of intraoperative lung ultrasound (ILU) as a safe and effective method of localization for difficult to visualize pulmonary nodules during Video-Assisted Thoracoscopic Surgery (VATS) and open thoracotomy. The secondary aim was to enhance knowledge on the morphological patterns of presentation of pulmonary nodules on direct ultrasound examination. Materials and methods: 131 patients with lung nodule and indication for surgery were enrolled. All patients underwent pre-operative imaging of the chest, including Chest Computed Tomography (CT) and Transthoracic Ultrasound (TUS), and surgical procedures for histological assessment of pulmonary nodules (VATS or open thoracotomy). Results: The identification of 100.00% of lung nodules was allowed by ILU, while the detection rate of digital palpation was 94.66%. It was not possible to associate any specific ILU echostructural pattern to both benign or malignant lesions. However, the actual histological margins of the lesions in the operating samples were corresponding to those visualized at ILU in 125/131 (95.42%) cases. No complications have been reported with ILU employment. Conclusions: In our experience, ILU performed during both open surgery and VATS demonstrated to be a reliable and safe method for visualization and localization of pulmonary nodules non previously assessed on digital palpation. In addition, ILU showed to allow a clear nodule’s margins’ definition matching, in most cases, with the actual histological margins.

Multi-disciplinary approach for the management of non-metastatic non-small cell lung cancer in the Middle East and Africa: Expert panel recommendations

The Middle East and Africa (MEA) region, a large geographical area, lies at the confluence of Asian, Caucasian and African races and comprises of a population with several distinct ethnicities. The course of management of non-small cell lung cancer (NSCLC) differs as per patients' performance status as well as stage of disease, requiring personalized therapy decisions. Although management of NSCLC has received a significant impetus in the form of molecularly targeted therapies and immune therapies in last few years, surgery remains gold standard for patients with early-stage disease. In case of unresectable disease, radiotherapy and chemotherapy are the primary management modalities. With newer therapies being approved for treatment of early stage disease, use of multi-disciplinary team (MDT) for comprehensive management of NSCLC is of prime importance. A group of experts with interest in thoracic oncology, deliberated and arrived at a consensus statement for the community oncologists treating patients with NSCLC in the MEA region. The deliberation was based on the review of the published evidence including literature and global and local guidelines, subject expertise of the participating panellists and experience in real-life management of patients with NSCLC. We present the proposed regional adaptations of international guidelines and recommends the MDT approach for management of NSCLC in MEA.

Breaking potentially bad news of cancer workup to well-informed patients by telephone versus in-person: A randomised controlled trial on psychosocial consequences

BACKGROUND

The use of telephone in delivering cancer care increases, but not in cancer workup. Current protocols for breaking bad news assume a single in-person meeting. Cancer workup involves multiple opportunities for patient information. We investigated the psychosocial consequences in gradually informed patients of receiving lung cancer workup results by telephone versus in-person.

METHODS

A randomised, controlled, open-label, assessor-blinded, single-centre trial including patients referred for invasive workup for suspected malignancy (clinical trials no. NCT04315207). Patients were informed on probable cancer at referral, after imaging, and on the day of invasive workup (Baseline visit). Primary endpoint: change (Δ) from baseline to follow-up (4 weeks after receiving workup results) in scores of a validated, sensitive, condition-specific questionnaire (COS-LC) assessing consequences on anxiety, behaviour, dejection and sleep.

RESULTS

Of 492 eligible patients, we randomised 255 patients (mean age: 68 years; female: 38%; malignancy diagnosed: 68%) to the telephone (n = 129) or in-person (n = 126) group. Groups were comparable at baseline and follow-up, and no between-groups difference in ΔCOS-LC was observed in the intention-to-treat population, or in subgroups diagnosed with or without malignancy.

CONCLUSION

Breaking final result of cancer workup by telephone is not associated with adverse psychosocial consequences compared to in-person conversation in well-informed patients.

A novel model for extrapleural cavity metastasis assessment in patients with lung cancer

Aim: To investigate the clinical value of tumor markers in extrapleural tumor metastasis assessment of newly diagnosed lung cancer patients. Materials & methods: This study retrospectively analyzed 306 patients diagnosed with lung cancer accompanied by tumor metastasis. Patients were grouped into extrapleural tumor metastasis and intrapleural tumor metastasis. Seven serum tumor markers were included for analysis. Results: The area under curves of receiver operating characteristic curve based on binning decision tree algorithm were above 0.8 in both training and validation sets. A scorecard with a score below 3 suggested extrapleural tumor metastasis in newly diagnosed lung cancer patients. Conclusion: The serum tumor marker-derived model is a convenient and fast approach for extrapleural cavity metastasis assessment, which may provide positive implications in newly diagnosed lung cancer patients.

Multidisciplinary care models for patients with lung cancer

Multidisciplinary care is the cornerstone of lung cancer treatment in the developed world, even though there is a relative lack of consistent evidence that this care model improves outcomes. In this review, we present the available literature regarding how to set up and run an efficient multidisciplinary care model for lung cancer patients with emphasis on team members' roles and responsibilities. Moreover, we present some limited evidence about multidisciplinary care and its impact on lung cancer outcomes and survival. This review provides simple guidance on setting up and running a multidisciplinary service for lung cancer patients. It highlights the importance of defined roles and responsibilities for team members. It also presents concise information based on the literature regarding the impact of multidisciplinary care in lung cancer outcomes (e.g. survival of patients undergoing lung cancer surgery).

A Multidisciplinary Lung Cancer Program: Does It Reduce Delay Between Diagnosis and Treatment?

INTRODUCTION

Lung cancer is the leading cause of cancer death in the USA, claiming more than 140,000 deaths annually. Delays in diagnosis and treatment can lead to missed opportunities for both curative and life prolonging therapies. This study aimed to evaluate duration of time to diagnosis and first treatment, as well as investigate reasons for delays in care.

METHODS

This retrospective study included all lung cancer cases diagnosed by Stony Brook's Lung Cancer Evaluation Center (LCEC) between 2013 and 2019. Demographic, radiologic, pathologic and clinical variables were investigated, including cancer staging, histology, and medical and family histories. Evaluations included the determination of median time from initial encounter to diagnosis, median time from diagnosis to start of treatment and an exploration of the factors that influence possible causes for delays in care.

RESULTS

The LCEC's comprehensive multidisciplinary lung nodule program yielded a median length of time from CT to PET of 11 days, PET to procedure of 13 days, procedure to treatment consult of 9 days, and from consult to treatment of 9 days. LCEC patients experienced an overall median of 44 days from initial presentation to first treatment compared to the national ideal of 62 days, thereby representing a 29% reduction in time from first CT to onset of treatment.

CONCLUSION

Delays in lung cancer diagnosis and treatment can negatively impact patient morbidity and mortality. This study suggests that a coordinated multidisciplinary lung cancer program may reduce delays in care, thereby improving patient outcomes.

Multidisciplinary team care in advanced lung cancer

Lung cancer is the most common cause of cancer mortality globally. A vast majority of lung cancer cases are diagnosed at advanced stages. Management of advanced lung cancer requires several diagnostic and therapeutic procedures provided by various specialists. To optimise the entire diagnostic and therapeutic process, a concept of care provided simultaneously by a multidisciplinary team (MDT) has been developed and implemented in specialised centres worldwide. Observational studies suggest that integrated and coordinated care increases adherence to clinical guidelines, significantly shortens the interval from diagnosis to treatment, and may increase survival and quality of life (QoL). Prospective studies are warranted to assess the real impact of MDT on treatment outcomes and to further refine this approach.

Accuracy of lung cancer staging in the multidisciplinary team setting

Accurate staging of lung cancer is of utmost importance in determining the stage-appropriate treatment and prognosis. Imaging tests which include contrast-enhanced computed tomography (CT) examination of the chest to include the liver and adrenal glands and 18-fluoro-2 deoxyglucose positron emission tomography (PET)/CT scan facilitate the initial tumor node metastasis (TNM) staging of the disease and provide guidance on the optimal biopsy site and biopsy method. The diagnostic and staging approach should be tailored to the individual patient according to risk, benefit, patient preferences, and available expertise. Diagnosis and staging should preferably be accomplished with a single procedure or the least number of invasive procedures if more than one is needed. Ideally, centers managing lung cancer patients should have a multidisciplinary thoracic oncology board prescribing personalized evidence-based management tailored to each individual patient. Multidisciplinary team (MDT) meetings provide a platform for key experts from various disciplines to contribute specific advice on the management of each individual patient. As assessment of mediastinal lymph node involvement is an important component of lung cancer staging, optimal mediastinal staging can be achieved with a variety of techniques that can be discussed and performed by the various specialists in the MDT. Despite a relative paucity of quality evidence that MDT contributes to improvements in lung cancer survival outcomes, this approach has evolved to become the standard of care in many centers around the world. Thoracic MDT has resulted in more focused and timely investigations for histopathologic diagnosis and disease staging which translate into earlier treatment initiation. Moreover, there is increasing evidence that MDT care facilitates and allows access to investigations that lead to improved accuracy of tumor and nodal staging. However, there is still a paucity of evidence on the accuracy of lung cancer staging in the MDT setting.

Preoperative staging of the mediastinum is an essential and multidisciplinary task

Mediastinal staging is a crucial step in the management of patients with NSCLC. With the recent development of novel techniques, mediastinal staging has evolved from an activity of interest mainly for thoracic surgeons to a joint effort carried out by many specialists. In this regard, the debate of cases in MDT sessions is crucial for optimal management of patients. Current evidence-based clinical guidelines for preoperative NSCLC staging recommend that mediastinal staging should be performed with increasing invasiveness. Image-based techniques are the first approach, although they have limited accuracy and findings must be confirmed by pathology in almost all cases. In this setting, the advent of radiomics is promising. Invasive staging depends on procedural factors rather than diagnostic performance. The choice between endoscopy-based or surgical procedures should depend on the local expertise of each centre. As the extension of mediastinal disease in terms of number of involved lymph nodes and nodal stations affects prognosis and the choice of treatment, systematic samplings are preferred over random targeted samplings. Following this approach, a diagnosis of single mediastinal nodal involvement can be unreliable if all reachable mediastinal nodal stations have not been assessed. The performance of confirmatory mediastinoscopy after a negative endoscopy-based procedure is controversial but currently recommended. Current indications of invasive staging in patients with radiologically normal mediastinum have to be re-evaluated, especially for central tumour location.

Fluoroscopy guided percutaneous biopsy in combination with bronchoscopy and endobronchial ultrasound in the diagnosis of suspicious lung lesions - the triple approach

Flexible bronchoscopy and endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) are the pulmonologists´ basic procedures for the biopsy of suspicious lung lesions. If inconclusive, other guiding-modalities for tissue sampling are needed, computed tomography performed by a radiologist, or – if available – radial EBUS or electromagnetic navigation biopsy.

We wanted to investigate if same-day X-ray fluoroscopy-guided transthoracic fine-needle aspiration biopsy (F-TTNAB) performed by the pulmonologist immediately after bronchoscopy and EBUS is a feasible alternative.

We retrospectively identified consecutive patients in whom F-TTNAB followed a bronchoscopy and EBUS in the same séance. Patients in whom the suspicion of malignancy was invalidated after complete work up were followed for six months to identify false-negative cases.

In total 125 patients underwent triple approach (bronchoscopy, EBUS and F-TTNAB) during the same séance. Malignancy was diagnosed in 86 (69%), and 77 of these (90%) were primary lung cancers. The diagnostic yield of F-TTNAB for malignancy was 77%, and sensitivity was 90%. Pneumothorax occurred in 35 (28%) patients, and was administered with pleural drainage in 22 (18% of all patients). No cases of prolonged haemoptysis were observed. The risk of pneumothorax differed insignificantly with lesion size ≤2.0 cm (27%) versus >2.0 cm (29%).

We conclude that it is feasible for pulmonologist to perform F-TTNAB immediately after endoscopy as a combined triple approach in a fast-track workup of suspected lung cancer.

The clinical value of carcinoembryonic antigen for tumor metastasis assessment in lung cancer

Background

Carcinoembryonic antigen (CEA) as a diagnostic or prognostic marker has been widely studied in patients with lung cancer. However, the relationship between serum CEA and tumor metastasis in lung cancer remains controversial. This study aimed to investigate the ability of serum CEA to assess tumor metastasis in lung cancer patients.

Methods

We performed a retrospective analysis of 238 patients diagnosed with lung cancer from January to December 2016 at pneumology department of Dazhou Central Hospital (Dazhou, China). Serum CEA levels were quantified in each patient at the time of diagnosis of lung cancer. Metastasis was confirmed by computed tomography (CT), and/or positron emission tomography (PET) and/or surgery or other necessary detecting methods.

Results

Of the 213 patients eligible for final analysis, 128 were diagnosed with metastasis and 85 were diagnosed without metastasis. Compared to non-metastatic patients, the serum CEA was markedly higher in patients with metastasis (p < 0.001), and the area under the curve (AUC) was 0.724 (95% CI [0.654–0.793]). Subsequent analyses regarding the number and location of tumor metastases showed that CEA also had clinical value for multiple metastases versus single metastasis (AUC = 0.780, 95% CI [0.699–0.862]) and distant metastasis versus non-distant metastasis (AUC = 0.815, 95% CI [0.733–0.897]). In addition, we found that tumor size, histology diagnosis, age and gender had no impact on the assessment performance of CEA.

Conclusion

Our study suggested the serum CEA as a valuable marker for tumor metastases assessment in newly diagnosed lung cancer patients, which could have some implications in clinical application.

Competence in flexible bronchoscopy and basic biopsy technique

Diagnostic bronchoscopy and tissue sampling techniques using forceps (endobronchial biopsy [EBB] and transbronchial biopsies [TBB]) or needle aspiration (transbronchial needle aspiration-TBNA), all performed with a flexible bronchoscope, are the basic elements of any interventional procedure. The flexible fibrobronchoscopy allows the visualization of the airways and is used both for diagnostic and therapeutic purposes. The working channel of both fibrobronchoscopes with optical fibers and videobronchoscopes, even if of relatively small diameter, allows the insertion of various diagnostic and therapeutic accessories. Fiber optic systems have been widely replaced by video cameras using a miniaturized charge-coupled device camera positioned at the end of the scope that provides electronic transmission of images to a monitor. The indications for both diagnostic and therapeutic fibrobronchoscopy derive from a correct evaluation of symptoms and objective signs of the patient and from the correct interpretation of imaging methods. Although bronchoscopy techniques keep evolving at a rapid pace, basic procedures such as bronchoalveolar lavage, transbronchial lung biopsy, and transbronchial needle aspiration still play a key role in pulmonary disease diagnostics, and therefore, these methods must still be part of the training of interventional pulmonologists. Trainees will acquire a thorough knowledge of thoracic anatomy and become skilled in the interpretation of thoracic imaging, after which they will be given a theoretical and practical training course on virtual reality simulators, on animal or cadaver models, the effectiveness of which has been fully demonstrated by scientific studies. Specific DOPS tests have been developed for a qualitative evaluation of procedures on simulators, on animal models and on the patient.

Safety of endobronchial ultrasound-guided transbronchial needle aspiration in patients with lung cancer within a year after percutaneous coronary intervention

Background

Endobronchial ultrasound‐guided transbronchial needle aspiration (EBUS‐TBNA) may be necessary for patients with incidental lung cancer during or after coronary intervention. Although EBUS‐TBNA is quite safe, the safety in patients who recently received percutaneous coronary intervention (PCI) has not been demonstrated. The aim of this study was to assess the safety of EBUS‐TBNA in patients with lung cancer who underwent PCI within one year.

Methods

We retrospectively reviewed the medical records of 24 patients who underwent EBUS‐TBNA within one year after PCI between May 2009 and June 2017. Cardiovascular complications (death, myocardial infarction, arrhythmia, and acute heart failure) were assessed as primary outcomes. Procedural‐related complications were assessed as secondary outcomes.

Results

The coronary artery diseases requiring PCI were: myocardial infarction (n = 10), unstable angina (n = 10), stable angina (n = 2), and silent ischemia (n = 2). The median interval between PCI and EBUS‐TBNA was 125 days (interquartile range: 66–180). Atrial fibrillation with a rapid ventricular response temporarily occurred in one patient after EBUS‐TBNA. No other significant cardiovascular complications were encountered. Fifteen patients were administered an anti‐thrombotic agent the day of EBUS‐TBNA, while four had ceased taking the agent < 4 days before EBUS‐TBNA, however, there was no significant bleeding among those patients.

Conclusion

EBUS‐TBNA was safe and did not cause serious adverse events in patients with lung cancer who required tissue confirmation or mediastinal staging within one year after PCI. Incidental lung cancer found during or after a coronary intervention should be actively evaluated by EBUS‐TBNA.

Lung cancer and chronic obstructive pulmonary disease: From a clinical perspective

Chronic obstructive pulmonary disease (COPD) and lung cancer are devastating pulmonary diseases that commonly coexist and present a number of clinical challenges. COPD confers a higher risk for lung cancer development, but available chemopreventive measures remain rudimentary. Current studies have shown a marked benefit of cancer screening in the COPD population, although challenges remain, including the common underdiagnosis of COPD. COPD-associated lung cancer presents distinct clinical features. Treatment for lung cancer coexisting with COPD is challenging as COPD may increase postoperative morbidities and decrease survival. In this review, we outline current progress in the understanding of the clinical association between COPD and lung cancer, and suggest possible cancer prevention strategies in this patient population.

Treatment of limited disease small cell lung cancer: the multidisciplinary team

Small cell lung cancer (SCLC) presents multiple interdisciplinary challenges with several paradigm shifts in its treatment in recent years. SCLC treatment requires multidisciplinary management and timely treatment. The aim of this review is to focus on the team management aspects in the treatment of limited disease SCLC and how this can contribute towards improving outcomes.

Clinical Equipoise and Shared Decision-making in Pulmonary Nodule Management. A Survey of American Thoracic Society Clinicians

RATIONALE

Guidelines for pulmonary nodule evaluation suggest a variety of strategies, reflecting the lack of high-quality evidence demonstrating the superiority of any one approach. It is unclear whether clinicians agree that multiple management options are appropriate at different levels of risk and whether this impacts their decision-making approaches with patients.

OBJECTIVES

To assess clinicians' perceptions of the appropriateness of various diagnostic strategies, approach to decision-making, and perceived clinical equipoise in pulmonary nodule evaluation.

METHODS

We developed and administered a web-based survey in March and April, 2014 to clinician members of the American Thoracic Society. The primary outcome was perceived appropriateness of pulmonary nodule evaluation strategies in three clinical vignettes with different malignancy risk. We compared responses to guideline recommendations and analyzed clinician characteristics associated with a reported shared decision-making approach. We also assessed clinicians' likelihood to enroll patients in hypothetical randomized trials comparing nodule evaluation strategies.

RESULTS

Of 5,872 American Thoracic Society members e-mailed, 1,444 opened the e-mail and 428 eligible clinicians participated in the survey (response rate, 30.0% among those who opened the invitation; 7% overall). The mean number of options considered appropriate increased with pretest probability of cancer, ranging from 1.8 (SD, 1.2) for the low-risk case to 3.5 (1.1) for the high-risk case (P < 0.0001). As recommended by guidelines, the proportion that deemed surgical resection as an appropriate option also increased with cancer risk (P < 0.0001). One-half of clinicians (50.4%) reported engaging in shared decision-making with patients for pulmonary nodule management; this was more commonly reported by clinicians with more years of experience (P = 0.01) and those who reported greater comfort in managing pulmonary nodules (P = 0.005). Although one-half (49.9%) deemed the evidence for pulmonary nodule evaluation to be strong, most clinicians were willing to enroll patients in randomized trials to compare nodule management strategies in all risk categories (low risk, 87.6%; moderate risk, 89.7%; high risk, 63.0%).

CONCLUSIONS

Consistent with guideline recommendations, clinicians embrace multiple options for pulmonary nodule evaluation and many are open to shared decision-making. Clinicians support the need for randomized clinical trials to strengthen the evidence for nodule evaluation, which will further improve decision-making.

Acute myocardial infarction following erlotinib treatment for NSCLC: A case report

Erlotinib, an epidermal growth factor receptor tyrosine kinase inhibitor, is an oral targeted anticancer drug that is used to treat non-small cell lung cancer (NSCLC). Previous studies have confirmed that erlotinib is safe and is well-tolerated by patients. The most common adverse reactions observed following erlotinib treatment include a rash and mild diarrhea. In the current study, the first case of acute myocardial infarction following one month of treatment with erlotinib in a 63-year-old male NSCLC patient is presented. The present study highlights the importance of clinicians remaining cautious following erlotinib administration. In elderly NSCLC patients and those with a history of coronary heart disease, cardiac function must be carefully monitored following erlotinib treatment so that serious adverse reactions, such as myocardial infarction, may be identified early and treated quickly.

Improving outcomes in lung cancer: the value of the multidisciplinary health care team

Lung cancer is a major worldwide health burden, with high disease-related morbidity and mortality. Unlike other major cancers, there has been little improvement in lung cancer outcomes over the past few decades, and survival remains disturbingly low. Multidisciplinary care is the cornerstone of lung cancer treatment in the developed world, despite a relative lack of evidence that this model of care improves outcomes. In this article, the available literature concerning the impact of multidisciplinary care on key measures of lung cancer outcomes is reviewed. This includes the limited observational data supporting improved survival with multidisciplinary care. The impact of multidisciplinary care on other benchmark measures of quality lung cancer treatment is also examined, including staging accuracy, access to diagnostic investigations, improvements in clinical decision making, better utilization of radiotherapy and palliative care services, and improved quality of life for patients. Health service research suggests that multidisciplinary care improves care coordination, leading to a better patient experience, and reduces variation in care, a problem in lung cancer management that has been identified worldwide. Furthermore, evidence suggests that the multidisciplinary model of care overcomes barriers to treatment, promotes standardized treatment through adherence to guidelines, and allows audit of clinical services and for these reasons is more likely to provide quality care for lung cancer patients. While there is strengthening evidence suggesting that the multidisciplinary model of care contributes to improvements in lung cancer outcomes, more quality studies are needed.

Mediastinal and Hilar Lymph Node Measurements. Comparison of Multidetector-Row Computed Tomography and Endobronchial Ultrasound

RATIONALE

Multidetector-row chest computed tomography scan is a common initial imaging modality and endobronchial ultrasound is a minimally invasive diagnostic tool used to evaluate enlarged lymph nodes, but comparisons of imaging results are lacking.

OBJECTIVES

To determine the size of thoracic lymph nodes and the strength of agreement between each measurement from coronal plane computed tomography and static endobronchial ultrasound images.

METHODS

A retrospective review of consecutive patients who underwent endobronchial ultrasound-transbronchial needle aspiration of their lymph nodes because of clinical suspicion of benign or malignant thoracic disease.

MEASUREMENTS AND MAIN RESULTS

One hundred and twenty-four lymph nodes from the mediastinal (74.2%) and hilar (25.8%) stations were measured in 59 patients (mean age, 64.5 yr; 33 males). The mean (standard deviation) short-axis diameter on computed tomography was 14.1 (6.7) mm compared with 12.6 (6.6) mm on endobronchial ultrasound. Benign lymph nodes (n = 42) were larger on computed tomography than on endobronchial ultrasound (14.1 [6.2] vs. 11.5 [6.2] mm). Malignant lymph nodes (n = 35) were larger on endobronchial ultrasound than on computed tomography (17.3 [6.4] vs. 16.2 [6.7] mm). Sixty-five percent of the lymph nodes that were initially interpreted as not enlarged on axial computed tomography images measured greater than 10 mm on each imaging modality (12.5 [5.9] mm on computed tomography and 10.5 [5.6] mm on endobronchial ultrasound) and 24% of the sampled lymph nodes from this group contained malignant cells. Random-effects maximal likelihood linear regression showed a statistically significant difference between endobronchial ultrasound and the computed tomography method for measuring short-axis diameter in all 124 lymph nodes. There was a weak agreement (intraclass correlation, rho: 0.44 [95% confidence interval, 0.31-0.59]) between short-axis diameter measurements from each imaging modality.

CONCLUSIONS

Our single-center study shows that there was poor correlation between computed tomography and endobronchial ultrasound for the measurement of mediastinal and hilar lymph nodes. Malignant cells were recovered by ultrasound-guided needle aspiration from a substantial fraction of lymph nodes that were initially interpreted as normal in size. If these findings are confirmed, new criteria may be needed for lymph node measurement on computed tomography that will guide selection of lymph nodes for endobronchial ultrasound-transbronchial needle aspiration.

Molecular Testing for Treatment of Metastatic Non-Small Cell Lung Cancer: How to Implement Evidence-Based Recommendations

The recent discovery of relevant biomarkers has reshaped our approach to therapy selection for patients with non-small cell lung cancer. The unprecedented outcomes demonstrated with tyrosine kinase inhibitors in molecularly defined cohorts of patients has underscored the importance of genetic profiling in this disease. Despite published guidelines on biomarker testing, successful tumor genotyping faces significant hurdles at both academic and community-based practices. Oncologists are now faced with interpreting large-scale genomic data from multiple tumor types, possibly making it difficult to stay current with practice standards in lung cancer. In addition, physicians' lack of time, resources, and face-to-face opportunities can interfere with the multidisciplinary approach that is essential to delivery of care. Finally, several challenges exist in optimizing the amount and quality of tissue for molecular testing. Recognizing the importance of biomarker testing, a series of advisory boards were recently convened to address these hurdles and clarify best practices. We reviewed these challenges and established recommendations to help optimize tissue acquisition, processing, and testing within the framework of a multidisciplinary approach.

Update in Lung Cancer 2014

In the past 2 years, lung cancer research and clinical care have advanced significantly. Advancements in the field have improved outcomes and promise to lead to further reductions in deaths from lung cancer, the leading cause of cancer death worldwide. These advances include identification of new molecular targets for personalized targeted therapy, validation of molecular signatures of lung cancer risk in smokers, progress in lung tumor immunotherapy, and implementation of population-based lung cancer screening with chest computed tomography in the United States. In this review, we highlight recent research in these areas and challenges for the future.

Current concepts in targeting chronic obstructive pulmonary disease pharmacotherapy: making progress towards personalised management

Chronic obstructive pulmonary disease (COPD) is a common, complex, and heterogeneous disorder that is responsible for substantial and growing morbidity, mortality, and health-care expense worldwide. Of imperative importance to decipher the complexity of COPD is to identify groups of patients with similar clinical characteristics, prognosis, or therapeutic needs, the so-called clinical phenotypes. This strategy is logical for research but might be of little clinical value because clinical phenotypes can overlap in the same patient and the same clinical phenotype could result from different biological mechanisms. With the goal to match assessment with treatment choices, the latest iteration of guidelines from the Global Initiative for Chronic Obstructive Lung Disease reorganised treatment objectives into two categories: to improve symptoms (ie, dyspnoea and health status) and to decrease future risk (as predicted by forced expiratory volume in 1 s level and exacerbations history). This change thus moves treatment closer to individualised medicine with available bronchodilators and anti-inflammatory drugs. Yet, future treatment options are likely to include targeting endotypes that represent subtypes of patients defined by a distinct pathophysiological mechanism. Specific biomarkers of these endotypes would be particularly useful in clinical practice, especially in patients in which clinical phenotype alone is insufficient to identify the underlying endotype. A few series of potential COPD endotypes and biomarkers have been suggested. Empirical knowledge will be gained from proof-of-concept trials in COPD with emerging drugs that target specific inflammatory pathways. In every instance, specific endotype and biomarker efforts will probably be needed for the success of these trials, because the pathways are likely to be operative in only a subset of patients. Network analysis of human diseases offers the possibility to improve understanding of disease pathobiological complexity and to help with the development of new treatment alternatives and, importantly, a reclassification of complex diseases. All these developments should pave the way towards personalised treatment of patients with COPD in the clinic.

Pulmonologist involvement, stage-specific treatment, and survival in adults with non-small cell lung cancer and chronic obstructive pulmonary disease

RATIONALE

Up to 80% of patients with lung cancer have comorbid chronic obstructive pulmonary disease (COPD). Many of them are poor candidates for stage-specific lung cancer treatment due to diminished lung function and poor functional status, and many forego treatment. The negative effect of COPD may be moderated by pulmonologist-guided management.

OBJECTIVES

This study examined the association between pulmonologist management and the probability of receiving the recommended stage-specific treatment modality and overall survival among patients with non-small cell lung cancer (NSCLC) with preexisting COPD.

METHODS

Early- and advanced-stage NSCLC cases diagnosed between 2002 and 2005 with a prior COPD diagnosis (3-24 months before NSCLC diagnosis) were identified in Surveillance, Epidemiology, and End Results tumor registry data linked to Medicare claims. Study outcomes included receipt of recommended stage-specific treatment (surgical resection for early-stage NSCLC and chemotherapy for advanced-stage NSCLC [advNSCLC]) and overall survival. Pulmonologist management was considered present if one or more Evaluation and Management visit claims with pulmonologist specialty were observed within 6 months after NSCLC diagnosis. Stage-specific multivariate logistic regression tested association between pulmonologist management and treatment received. Cox proportional hazard models examined the independent association between pulmonologist care and mortality. Two-stage residual inclusion instrumental variable (2SRI-IV) analyses tested and adjusted for potential confounding based on unobserved factors or measurement error.

MEASUREMENTS AND MAIN RESULTS

The cohorts included 5,488 patients with early-stage NSCLC and 6,426 patients with advNSCLC disease with preexisting COPD. Pulmonologist management was recorded for 54.9% of patients with early stage NSCLC and 35.7% of patients with advNSCLC. Of those patients with pulmonologist involvement, 58.5% of patients with early NSCLC received surgical resection, and 43.6% of patients with advNSCLC received chemotherapy. Pulmonologist management post NSCLC diagnosis was associated with increased surgical resection rates (odds ratio, 1.26; 95% confidence interval, 1.11-1.45) for early NSCLC and increased chemotherapy rates (odds ratio, 1.88; 95% confidence interval, 1.67-2.10) for advNSCLC. Pulmonologist management was also associated with reduced mortality risk for patients with early-stage NSCLC but not AdvNSCLC.

CONCLUSIONS

Pulmonologist management had a positive association with rates of stage-specific treatment in both groups and overall survival in early-stage NSCLC. These results provide preliminary support for the recently published guidelines emphasizing the role of pulmonologists in lung cancer management.

Lung cancer staging now and in the future

For a long time lung cancer was associated with a fatalistic approach by healthcare professionals. In recent years, advances in imaging, improved diagnostic techniques and more effective treatment modalities are reasons for optimism. Accurate lung cancer staging is vitally important because treatment options and prognosis differ significantly by stage. The staging algorithm should include a contrast computed tomography (CT) of the chest and the upper abdomen including adrenals, positron emission tomography/CT for staging the mediastinum and to rule out extrathoracic metastasis in patients considered for surgical resection, endosonography-guided needle sampling procedure replacing mediastinoscopy for near complete mediastinal staging, and brain imaging as clinically indicated. Applicability of evidence-based guidelines for staging of lung cancer depends on the available expertise and level of resources and is directly impacted by financial issues. Considering the diversity of healthcare infrastructure and economic performance of Asian countries, optimal and cost-effective use of staging methods appropriate to the available resources is prudent. The pulmonologist plays a central role in the multidisciplinary approach to lung cancer diagnosis, staging and management. Regional respiratory societies such as the Asian Pacific Society of Respirology should work with national respiratory societies to strive for uniform standards of care. For developing countries, a minimum set of care standards should be formulated. Cost-effective delivery of optimal care for lung cancer patients, including staging within the various healthcare systems, should be encouraged and most importantly, tobacco control implementation should receive an absolute priority status in all countries in Asia.

The lung cancer patient, the pneumologist and palliative care: a developing alliance

Considerable evidence is now available on the value of palliative care for lung cancer patients in all stages and at all times during the course of the disease. However, pneumologists and their institutions seem to be widely in arrears with the implementation of palliative care concepts and the development of integrated structures.

This review focuses on the available evidence and experience of various frequently unmet needs of lung cancer patients, especially psychological, social, spiritual and cultural ones. A PubMed search for evidence on these aspects of palliative care as well as on barriers to the implementation, on outcome parameters and effectiveness, and on structure and process quality was performed with a special focus on lung cancer patients.

As a consequence, this review particularly draws pneumologists’ attention to improving their skills in communication with the patients, their relatives and among themselves, and to establish team structures with more far-reaching competences and continuity than existing multilateral cooperations and conferences can provide. Ideally, any process of structural and procedural improvement should be accompanied by scientific evaluation and measures for quality optimisation.
