ABSTRACT

BACKGROUND: The first description of performing a new diagnostic procedure, cryobiopsy, in lung transplant recipients in Poland. METHODS: Three cases of patients after lung transplantation were analyzed in context of the procedure of cryobiopsy, which was performed in a hybrid room with a bronchoscopic video track and C-arm radiograph. Patients were subjected to complete anesthesia and intubated. Two or three sections with an average diameter of 5 mm were collected. RESULTS: The sections were large and fully diagnostic. In all 3 described cases they brought a decisive element into diagnosis. CONCLUSIONS: Cryobiopsy is a useful tool in the differential diagnosis of lesions and complications that occur after lung transplantation.

ABSTRACT

Emphysema is one of three main lung pathologies in Chronic Obstructive Pulmonary Disease, along with chronic bronchitis and small airway obstruction. The diagnosis is based on detection of low attenuation areas in lung tissue on chest Computed Tomography, either visual by a radiologist, or automatic by the applied Computed Tomography software. Results of the studies on the association between emphysema and lung cancer incidence are mixed. Many studies have demonstrated, that chronic lung diseases, like Chronic Obstructive Pulmonary Disease, are associated with lung cancer morbidity. There is also evidence, that emphysema can be related with worse prognosis in patients with detected lung cancer. In this review article we aim to summarize current knowledge about emphysema detection and evaluation on Computed Tomography, both quantitative and qualitative. We also summarize current data on correlation between emphysema and lung cancer, as well as its potential use in selecting patients, who would most benefit from lung cancer screening.

ABSTRACT

BACKGROUND: In 2010, the World Health Organisation recommended implementation of screening programmes in four groups of diseases-neoplasms, cardiovascular diseases (CVD), diabetes mellitus (DM) and chronic obstructive pulmonary disease (COPD). It is due to the fact that they share the same, modifiable risk factors. METHODS: Between 2009 and 2011, 8637 heavy smokers (aged 50-75, smoking history >20 pack-years) were screened in the Pomeranian Pilot Lung Cancer Screening Programme (PPP) in Gdansk, Poland. We looked at 5-year follow-up and analysed the medical events and comorbidities of all participants. One health care provider in the Polish health care system provides a unique opportunity to gather most reliable data on all medical events in each person. RESULTS: In 52.0% of lung cancer screening participants CVD (33.5%), DM (26.0%) and COPD (21.0%) were diagnosed. Prevalence of these diseases is higher in lung cancer patients than in the non-cancer screening group (P < 0.0001). One hundred and seven (1.2%) lung cancers were diagnosed during PPP programme performance and another 382 cases (4.4%) in the 5-year follow-up, so the potential mean annual lung cancer detection rate is 0.77%. CONCLUSIONS: Lung cancer screening programme offers a great potential for joint screening of lung cancer, CVD, diabetes and COPD.

ABSTRACT

OBJECTIVES: The European Society of Thoracic Surgeons' recommendations confirm the implementation of lung cancer screening in Europe. We compared 2 screening programmes, the Pilot Pomeranian Lung Cancer Screening Programme (pilot study) and the Moltest Bis programme, completed in a single centre. METHODS: A total of 8649 healthy volunteers (aged 50-75 years, smoking history ≥20 pack-years) were enrolled in a pilot study between 2009 and 2011, and a total of 5534 healthy volunteers (aged 50-79, smoking history ≥30 pack-years) were enrolled in the Moltest Bis programme between 2016 and 2017. Each participant had a low-dose computed tomography scan of the chest. Participants with a nodule diameter of >10 mm or with suspected tumour morphology underwent a diagnostic work-up in the pilot study. In the Moltest Bis programme, the criteria were based on the volume of the detected nodule on the baseline low-dose computed tomography scan and the volume doubling time in the subsequent rounds. RESULTS: Lung cancer was diagnosed in 107 (1.24%) and 105 (1.90%) participants of the pilot study and of the Moltest Bis programme, respectively (P = 0.002). A total of 300 (3.5%) and 199 (3.6%) patients, respectively, were referred for further invasive diagnostic work-ups (P = 0.69). A total of 125 (1.5%) and 80 (1.5%) patients, respectively, underwent surgical resection (P = 0.74). The number of resected benign lesions was similar: 44 (35.0%) and 20 (25.0%), respectively (P = 0.13), but with a downwards trend. Lobectomies and/or segmentectomies were performed in 84.0% and 90.0% of patients with lung cancer, respectively (P = 0.22). Notably, patients in the Moltest Bis programme underwent video-assisted thoracoscopic surgery more often than did those in the pilot study (72.5% vs 24.0%, P < 0.001). Surgical patients with stages I and II non-small-cell lung cancer (NSCLC) accounted for 83.4% of the Moltest patients and 86.4% of the pilot study patients (P = 0.44). CONCLUSIONS: Modified inclusion criteria in the screening programme lead to a higher detection rate of NSCLC. Growing expertise in lung cancer screening leads to increased indications for minimally invasive surgery and an increased proportion of lung-sparing resections. A single-team experience in lung cancer screening does not lead to a major reduction in the rate of diagnostic procedures and operations for non-malignant lesions.

ABSTRACT

PURPOSE: It is crucial to obtain a specific diagnosis before treatment of chest pathology is initiated. The purpose of the study is to present the utility of percutaneous biopsies, core and fine-needle aspiration, in various thoracic lesions, and related complications. MATERIAL AND METHODS: A total of 593 transthoracic biopsies were performed in the Department of Radiology between 2013 and 2016. Fine-needle aspiration biopsy (FNAB) and core biopsy (CB) were implemented. The procedures were divided into four groups according to the location of the pathology: lung lesions (LL - 540), mediastinal masses (MM - 25), chest wall tumours (CWT - 13), and pleural lesions (PL - 15). The lung lesion group was divided into two subgroups: lung nodules and lung infiltrations. All groups were analysed in respect of diagnostic accuracy, pathological findings, and complication rate. RESULTS: Pathological diagnosis was confirmed in 447 cases after all 593 procedures. The sensitivity of malignancy diagnosis in the group of lung tumours was 75% for FNAB and 89% for CB. The sensitivity in other groups, where CB was a preferable technique, was counted for lung infiltration, mediastinal masses, chest wall tumours, and pleural lesions and amounted to 83.3%, 90.9%, 100%, and 85.7%, respectively. In the group of lung tumours malignancy was confirmed most commonly (79%), while in the lung infiltration group benign processes dominated (83%). There was no statistical difference between the pneumothorax rate after CB and FNAB. Haemoptysis appeared more often after CB. CONCLUSIONS: FNAB and CB are useful, safe, and sensitive tools in the diagnostic work-up. They can both be used to diagnose almost all chest pathologies.

ABSTRACT

INTRODUCTION: Lung cancer screening with low-dose computed tomography (LDCT) is one of the most promising tools for reducing mortality from lung cancer. OBJECTIVES: The aim of the study was to evaluate the results of an open-access lung cancer screening program with LDCT. PATIENTS AND METHODS: In total, 8649 asymptomatic volunteers between 50 and 75 years of age with a smoking history of at least 20 pack-years underwent LDCT screening. The presence of lung nodules with a diameter of less than 5 mm required a follow-up control visit after 12 months, and with a diameter of 5 to 10 mm--after 3, 6, and 12 months. Patients with a nodule of more than 10 mm in diameter required further diagnostic workup. RESULTS: Lung nodules were detected in 4694 individuals (54%). Lung cancer was diagnosed in 107 patients (1.24%). Of 8649 participants, 300 (3.5%) were referred for further diagnostic workup, and 125 (1.5%) underwent surgical resection (81 because of malignant lesions; 44, benign lesions). Eighty-one participants (75%) underwent surgery with a curative intent, and 26 participants underwent oncological treatment. There were no perioperative deaths. The majority of surgical patients underwent lobectomy (video-assisted, in 30 patients; and open, in 38 patients). Stage I non-small cell lung cancer was detected in 64 of the surgical patients (79%). CONCLUSIONS: The detection rate of lung cancer in the screening program with low-dose computed tomography is relatively low but patients were diagnosed at a very early stage of the disease compared with standard clinical practice.

ABSTRACT

INTRODUCTION: Lung cancer is the most common cause of cancer-related death worldwide, killing almost 22,000 people in Poland every year. Low-dose computed tomography (LDCT) is the most promising tool of secondary prophylaxis leading to early detection and thus successful treatment of this malignancy. Knowledge about socio-demographic factors that affect participation in lung cancer early detection programs is essential for the future design and implementation of such programs. MATERIAL AND METHODS: Among the 8649 participants of the Pomeranian Lung Cancer Screening Program (PLCSP), 1619 individuals responded to a questionnaire that had been designed to assess socio-demographic data of participants at high risk of developing lung cancer. The survey was conducted on-site after reception of results by the program participants. RESULTS: Among the survey participants, 777 (48%) were current cigarette smokers. The majority of them represented low or medium level of wealth status. The respondents positively evaluated the promotional campaign during the PLCSP, although 43% of them indicated family and friends as a source of information about the program. As the most important action that stimulated the participation, 46% of the respondents indicated the awareness campaign involving a celebrity, and 45% of them indicated the presence of cancer in the family. The influence of healthcare employees on the participation in the screening program was minimal. More than half of the respondents (53%) declared a willingness to co-finance a similar prophylactic program in the future in an amount not exceeding 100 PLN. CONCLUSIONS: An effective promotional campaign in the media, the influence of family and a campaign involving a celebrity promoted attendance at the screening program. The influence of healthcare employees on the participation in the program was minimal. The majority of the screened population declared a willingness to actively participate in the costs of LDCT examination.

ABSTRACT

OBJECTIVES: Low-dose computed tomography (LDCT) screening improves lung cancer prognosis but also results in diagnostic work-up and surgical treatment in many individuals without cancer. Therefore, we analysed the procedures that screening participants underwent to better understand the extent of overdiagnosis. METHODS: Between 2009 and 2011, 8649 healthy volunteers aged 50-75 years with a 20 pack-year smoking history underwent LDCT screening, of whom individuals with detected lung nodules had 2 years control. Participants with a nodule >10 mm in diameter or with suspected tumour morphology underwent diagnostic work-up: 283 (6%)/4694 (54%) screened participants had detected lung nodules. One hundred and four individuals underwent surgery, 27 underwent oncological treatment and 152 without a cancer diagnosis underwent further follow-up with LDCT. RESULTS: In 75% of participants accepted for diagnostic work-up and 25% of surgical patients, the procedures were unnecessary. In 70 (24.7%) participants, a specific diagnosis was obtained mainly due to the low efficacy of fine needle aspiration biopsy [sensitivity, 65.2%; negative predictive value (NPV), 95.9%] and bronchofiberoscopy (sensitivity, 71.4%; NPV, 50%) caused by overinterpretation of LDCT [positive predictive value (PPV), 2%]. Of 104 (36.7%) surgical patients, 43 (41.4%) had a preoperative cancer diagnosis, and 61 (58.6%) underwent surgery without pathological examination. In the latter group, intervention was justified in 35 (57.3%) patients. Complications occurred in 49 (17.3%) participants subjected to diagnostic work-up. In surgical patients, 67 (64.4%) malignant and 37 (35.6%) benign lesions were resected. In the latter group, intervention was justified in only 11 (29.7%) patients. No patient died because of diagnostic or treatment procedures during the study. The complication rate was 14.5% in the malignant and 10.8% in the benign groups. A neoplasm was found in 94 screening participants, of whom 67 (71.3%) underwent surgery; the remaining 27 (28.7%) patients were not surgical candidates. Adenocarcinoma accounted for 49/67 (73%) patients who underwent surgery for non-small-cell lung cancer (NSCLC); 56/67 (84%) patients had stage I NSCLC, and 26/67 (38%) underwent video-assisted thoracoscopic surgery lobectomy. CONCLUSIONS: Futile diagnostic work-ups and operations must be reduced before LDCT screening can be broadly used. Stage I adenocarcinoma dominated in the NSCLC patients who underwent surgery.

ABSTRACT

BACKGROUND: There is increasing evidence that suggests that particular histopathologic types of non-small-cell lung cancer (NSCLC) display distinct molecular characteristics. We analyzed, in lung squamous cell carcinoma (SCC) and adenocarcinoma (AC), the expression of 8 genes that constitute 2 previously reported prognostic expression signatures in NSCLC. METHODS: Fresh-frozen tumor and normal lung samples were obtained at surgery from 135 patients with stage I-III NSCLC (89 (65.9%) SCC, 46 (34.1%) AC). Expression of CSF1 (colony stimulating factor for macrophages), carbonic anhydrase 9 (CA9), epithelial growth factor receptor (EGFR), dual specificity phosphatase 6 (DUSP6), v-erb-b2 erythroblastic leukemia viral oncogene homolog 3 (ERBB3), monocyte to macrophage differentiation-associated (MMD), lymphocyte-specific protein tyrosine kinase (LCK) and signal transducer and activator of transcription 1 (STAT1) was assessed in SCC, AC, and in normal lung by quantitative reverse transcriptase - polymerase chain reaction (qRT-PCR). Metastasis-free survival was analyzed according to the median value of gene expression in the entire NSCLC cohort and separately in SCC and AC. RESULTS: Expression of CA9, CSF1, DUSP6, STAT1, and MMD differed between NSCLC and normal lung. EGFR was more abundant in SCC compared with AC, whereas the reverse was true for DUSP6 and ERBB3. A high expression of CSF1 correlated with shorter metastasis-free survival in the entire NSCLC group (P = .016) and in SCC (P = .049) and AC (P = .034) cohorts. CONCLUSIONS: Several genes considered prognostic in NSCLC showed significantly different expression in SCC and AC, and thus should be analyzed separately in these 2 subtypes for their prognostic significance. CSF1 is similarly expressed in SCC and AC, and portends a poor outcome in the entire group of patients with NSCLC, and in SCC and AC when considered separately.
