EGFR, KRAS, and BRAF mutational profiles of female patients with micropapillary predominant invasive lung adenocarcinoma

Background/aim: This study aimed to analyze EGFR, KRAS, and BRAF mutations in females with micropapillary predominant invasive lung adenocarcinoma and their relationships with immunohistochemical and clinicopathological patterns. Materials and methods: A total of 15 females with micropapillary lung adenocarcinoma were selected. Mutational analysis of the EGFR, KRAS, and BRAF genes was carried out. Information regarding the demographic data, tumor size, treatment, and survival time for each patient was collated, and the predominant cell type, secondary architectural growth patterns, psammoma bodies, necrosis, and visceral pleural and angiolymphatic invasions were evaluated. Results: We identified EGFR mutation in six cases, KRAS mutation in three cases, and BRAF mutation in one case. EGFR, c-kit, VEGFR, and bcl-2 positivity was observed in ten, seven, four, and six cases, respectively. All cases were positive for VEGF (strong positivity in 11 cases and weak positivity in four cases) and bcl-2 (strong positivity in nine cases and weak positivity in six cases). Seven (46.6\%) cases were positive for c-kit and 10 (66.6\%) cases were positive for EGFR. Conclusion: EGFR mutation occurred at a higher incidence rate in micropapillary predominant invasive adenocarcinoma than has previously been found in conventional lung adenocarcinomas. KRAS mutation was observed as having a similar frequency to what was previously observed, but the frequency of BRAF mutation was lower than previously reported

Clinical Impact Of Visceral Pleural, Lymphovascular And Perineural Invasion In Completely Resected Non-Small Cell Lung Cancer

Objectives: This study is conducted to show the relationship between visceral pleural, lymphovascular, and perineural invasion, and other clinicopathologic characteristics and their significance as prognostic factors. Methods: The clinicopathologic characteristics of 289 patients who underwent a potentially curative surgical resection between 2000 and 2009 in our clinic were reviewed retrospectively. The prognostic factors were then evaluated by univariate and multivariate analysis. The patients who were given neoadjuvant-adjuvant chemotherapy and/or radiotherapy and who died due to postoperative mortality were excluded. Data from 188 patients were analyzed. Results: Out of the 188 patients (108 diagnosed as adenocarcinoma and 80 squamous cell carcinoma), 66 patients had lymphovascular invasion, 53 patients had perineural invasion, and 92 patients had visceral pleural invasion. Visceral pleural invasion was related with T factor, tumor histology, dimension, stage, and differentiation. Lymphovascular invasion was related with N status and stage. Perineural invasion was observed more frequently in tumors with moderate/poor differentiation. Visceral pleural and lymphovascular invasion were found to be poor prognostic factors but we could not show statistically meaningful effect of perineural invasion on survival. Conclusion: The presence of visceral pleural or lymphovascular invasion can show higher risk of mortality whereas perineural invasion has no effect on prognosis.

Starry sky sign: A prevalent sonographic finding in mediastinal tuberculous lymph nodes

Background and Objectives: We report a prevalent finding in tuberculous lymphadenitis (TL): Starry sky sign, hyperechoic foci without acoustic shadows over a hypoechoic background. Materials and Methods: We retrospectively searched the database for a possible relationship of starry sky sign with a specific diagnosis and also the prevalence and accuracy of the finding. Results: Starry sky sign was found in 16 of 31 tuberculous lymph nodes, while none of other lymph nodes (1,015 lymph nodes) exhibited this finding; giving a sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of 51.6\%, 100\%, 100\%, 98.5\%, and 98.5\%, respectively. Conclusion: Bacteriologic and histologic findings are gold standard in the diagnosis of tuberculosis, but this finding may guide the bronchoscopist in choosing the more pathologic node within a station and increase the diagnostic yield as it may relate to actively dividing mycobacteria

Retrospective evaluation of patients with organizing pneumonia: is cryptogenic organizing pneumonia different from secondary organizing pneumonia?

WOS: 000419200200001PubMed ID: 28621243Introduction: Organizing pneumonia (OP) is an uncommon clinic opathological situation among lung diseases. If no underlying cause can be detected, it is named as cryptogenic OP (COP). In this study, the etiologic and clinical characteristics of patients diagnosed as OP in our hospital in the last ten years were evaluated retrospectively. It was also aimed to make a comparison between COP and secondary OP patients. Materials and Methods: One hundred sixty-five patients diagnosed as OP pathologically in the 10 year period from August 2003 to August 2013 were included into that study. Patients' data were evaluated retrospectively from the medical records. Results: One hundred sixty five patients pathologically diagnosed as OP were included. Diagnostic methods were trans-thoracic fine-needle biopsy (TTFNB) in 89 (53.9%) patients, open lung biopsy (lobectomy, wedge resection, segmentectomy) in 52 (31.5%) patients and transbronchial biyopsy (TBB) in 24 (14.5%) patients. One hundred (60.6%) of the patients were defined as COP and 65 (39.4%) as secondary OP. Cough, fatigue and dyspnea were the most common symptoms on admission. We detected OP cases secondary to anthracosis and cyst hydatic besides other well known etiologies. In 61 patients, the main radiologic manifestation was multiple bilateral patchy consolidation typical for OP. In 76 patients focal lesions (solid mass, cavitating mass lesion) and in 6 patients infiltrative opacities were detected radiologically. Conclusion: There is no difference between properties of OP from clinical, laboratory and radiologic finding sin the criptogenic and seconder form of OP. Although it is not asserted, cyst hidatic and anthracosis could be kept in mind for the list of underlying ethiologies for secondary OP

Risk factors and maximum standardized uptake values within lymph nodes of anthracosis diagnosed by endobronchial ultrasound-guided transbronchial needle aspiration

Background/aim: Enlarged mediastinal lymph nodes can result from serious etiologies including granulomatous disease, neoplasia, etc., and a rare condition called anthracosis. The aim of this study was to determine the incidence of risk factors and the uptake values within the anthracotic lymph nodes. Materials and methods: 106 patients who underwent endobronchial ultrasound transbronchial needle aspiration and were diagnosed as having anthracosis were analyzed retrospectively. Patients with positive confirmation by surgical biopsies or a 1-year follow-up period were enrolled. Results: 201 lymph nodes were sampled from 106 patients. Subcarinal and interlobar lymph nodes were the most commonly affected stations (36.8\% and 34.3\%, respectively). The mean durations of exposure to biomass and cigarette smoke were 35.5 and 33 years, respectively. The mean maximum standardized uptake value (SUVmax) within the lymph nodes was 4.76. The SUVmax of the patients with associated malignancy was 4.19 and the SUVmax of nonmalignant patients was 5.28. This difference was statistically significant (P = 0.009). Conclusion: These findings suggest that anthracosis also affects the mediastinal and hilar stations; it should be considered in differential diagnosis in patients with mediastinal and hilar lymphadenopathies with intense uptake on positron emission tomography scans, especially when there is a history of exposure to known risk factors

Comprehensive out-patient pulmonary rehabilitation: Treatment outcomes in early and late stages of chronic obstructive pulmonary disease

Background : The aim was to evaluate the outcomes of a comprehensive pulmonary rehabilitation (PR) in chronic obstructive pulmonary disease (COPD) and to establish whether in early disease stage PR is as effective as in late stages of disease. Methods : A total of 55 stable COPD patients, 28 with early and 27 with late disease stages, were assessed. Patients underwent a comprehensive out-patient PR program for 8 weeks. To eluciate the effects of PR and compare the level of improvement; lung function, dyspnea sensation [Medical Research Council (MRC)], body composition [body mass index (BMI), fat free mass (FFM), fat free mass index (FFMI)], exercise capacity [incremental shuttle walking test, endurance shuttle walking test], health related quality of life (HRQoL) with St. George Respiratory Disease Questionnaire, psycohological status (Hospital anxiety-depression (HAD) scale) were evaluated before and after PR. Results : At the end of PR in the early disease stage group, the improvement in forced vital capacity (FVC) reached a statistically significant level (P < 0.05). In both disease stages, there were no significant differences in BMI, FFM, and FFMI. The decrease in exertional dyspnea for the two groups evaluated with the modified BORG scale were not found statistically significant, though the dyspnea scores evaluated with MRC showed significant improvements (P < 0.001). HRQoL and exercise capacity were significantly improved for the two groups (P < 0.001). Psychological status evaluated with the HAD scale improved after PR (P < 0.001) both in early and late stages. Gainings in the study parameters did not differ in the early and the late disease stages. Conclusions : These results showed that patients with COPD had benefited from a comprehensive PR program in an out-patient setting regardless of disease severity. Even patients with earlier stage of disease should be referred and encouraged to participate in a PR program

PET-CT guided curative conformal radiation therapy in limited stage small cell lung cancer.

The prognosis of small cell lung cancer (SCLC) has been improving with the advances in diagnostic and therapeutic modalities. Positron emission tomography/computed tomography (FDG-PET/CT) which has been studied in non-small cell lung cancer (NSCLC) for a long time, and it has only recently been applied to SCLC. Therefore we sought to observe firstly the prognostic importance of the FDG uptake in limited disease small cell lung cancer (LD-SCLC) patients and secondly the clinical outcomes and toxicity profiles of LD-SCLC patients treated with conformal radiation therapy (RT) using FDG-PET/CT simulation
