Many small series have suggested that the prognosis of lung tumors with giant cells is worse than that of most other forms of non-small-cell lung cancer (NSCLC), [11] including squamous cell carcinoma, [42] and spindle cell carcinoma. [42] The overall five-year survival rate in GCCL varies between studies but is generally considered to be very low.
In a retrospective review of 204 children with lung tumors, pleuropulmonary blastoma and carcinoid tumor were the most common primary tumors (83% of the 204 children had secondary tumors spread from cancers elsewhere in the body). [1] Pleuropulmonary blastoma is regarded as malignant. The male:female ratio is approximately one.
Lung cancer, also known as lung carcinoma, is a malignant tumor that begins in the lung. Lung cancer is caused by genetic damage to the DNA of cells in the airways, often caused by cigarette smoking or inhaling damaging chemicals. Damaged airway cells gain the ability to multiply unchecked, causing the growth of a tumor.
Solitary fibrous tumor (SFT), also known as fibrous tumor of the pleura, is a rare mesenchymal tumor originating in the pleura [1] or at virtually any site in the soft tissue including the seminal vesicle. [2] Approximately 78% to 88% of SFT's are benign and 12% to 22% are malignant. [3]
Inflammatory myofibroblastic tumor was initially regarded as a benign tumor that most often developed in the lung and less commonly in almost any organ system or tissue. Over time, however, IMT cases occurred in which the tumor spread into local tissues, metastasized to distal tissues, recurred after treatment, or consisted of neoplastic cells ...
CT-guided biopsy of peripheral typical carcinoid tumor. The definitive diagnosis is rendered by a microscopic examination, after excision.Typical carcinoids have cells with stippled chromatin and a moderate quantity of cytoplasm.
