Pulmonary high ‐grade fetal adenocarcinoma associated with cystic airspace: A case report
In conclusion, when treating elderly men with a smoking history, physicians need to carefully examine the walls of cystic airspaces on CT for fetal adenocarcinoma.Key pointsSignificant findings of the study•Pulmonary high‐grade fetal adenocarcinoma may be associated with emphysematous bullae manifesting as cystic air spaces as shown by computed tomography.What this study adds•When scanning by computed tomography, physicians should carefully examine the pulmonary cystic airspace walls in elderly men with a smoking history.
Conclusion: A COPD/emphysema based strategy for the selection of LCS candidates is feasible. The prevalence of LC in our high risk cohort was 2.31%. 64% of patients were operable, and median survival at 4 years was 94%.
Conclusions: The presence of COPD in surgically resected lung cancer reveals a higher percentage of recurrences, mortality and epidermoid carcinomas. Furthermore, in the emphysema phenotype more second tumors and in chronic bronchitis more recurrences have been found.
ConclusionsA markedly reduced area of normal lung on HRCT was a relevant radiologic predictor of survival.
Conclusions: No significant association was observed between preoperative biopsy (transbronchial biopsy and/or percutaneous lung biopsy) and lung cancer recurrence in patients with stage IA disease.
Conclusion: Neither of the viruses was found in samples from small-cell, non-small-cell (adenocarcinoma, squamous-cell carcinoma and large-cell neuroendocrine lung cancer), mixed-type and non-differentiated lung carcinoma, and non-cancerous lung tissues (from patients with pneumonia, emphysema and fibrosis).Pathobiology
CONCLUSION: Non-intubated (NITS) VATS lobectomy is considered a safe procedure, satisfying all aspects of oncological guidelines. The postoperative drainage period was shorter caused by the complete atelectasis during the surgery. PMID: 28621182 [PubMed - in process]
Conclusions: Cystic airspaces preceded by nodules can evolve into NSCLCs. Wall thickening and/or mural nodularity may develop. Location in the periphery of the upper lobes, emphysema, additional cystic lesions or ground-glass nodules, lymphadenopathy, and prior lung cancer should further increase suspicion. Cystic airspaces on CT can be due to a check-valve mechanism obstructing the small airways, lepidic growth of adenocarcinoma in an area of emphysema, cystification of tumor due to degeneration, or adenocarcinoma growing along the wall of a preexisting bulla. KRAS mutations are the predominant genetic alterations.
Introduction: COPD is known to be associated with increased risk of lung cancer; however, it is unclear how patients with COPD should be followed up to detect the development of lung cancer.Aim: To investigate incidence and clinical characteristics of lung cancer in patients with COPD, using data from a 10-year prospective observational cohort study.Methods: A total of 279 subjects with COPD (GOLD 1, 26%; GOLD 2, 45%; GOLD 3, 24%; GOLD 4, 5%) participated in the Hokkaido COPD cohort study. Chest CT scans were taken every year during the first 5 years for all subjects and for another 5 years for those who agreed.Results: 39...
CONCLUSIONS: Over the years VATS lobectomy became a rutin procedure at our institution. Nowadays more than two-thirds of lobectomies are performed with minimally invasive technique. Taking the learning curve of the four thoracic surgeons into consideration, our results correlate with international data. PMID: 27644925 [PubMed - as supplied by publisher]
CONCLUSIONS: Patients with lung cancer and CPFE had poor prognoses regardless of apparently good pulmonary function and showed quite high postoperative mortality rates. A lower %VC that might reflect the severity of pulmonary fibrosis was associated with poor prognoses. PMID: 25956575 [PubMed - as supplied by publisher]
