Bone metastasis, or osseous metastatic disease, is a category of cancer metastases that result from primary tumor invasions into bones. Bone-originating primary tumors such as osteosarcoma , chondrosarcoma , and Ewing sarcoma are rare; the most common bone tumor is a metastasis. [ 1 ]
Lung cancer is the most diagnosed and deadliest cancer worldwide, with 2.2 million cases in 2020 resulting in 1.8 million deaths. [3] Lung cancer is rare in those younger than 40; the average age at diagnosis is 70 years, and the average age at death 72. [2] Incidence and outcomes vary widely across the world, depending on patterns of tobacco use.
Small-cell lung carcinoma (SCLC) has long been divided into two clinicopathological stages, termed limited stage (LS) and extensive stage (ES). [8] The stage is generally determined by the presence or absence of metastases, whether or not the tumor appears limited to the thorax, and whether or not the entire tumor burden within the chest can feasibly be encompassed within a single radiotherapy ...
If metastases are both local and regional, the prognosis is worse. Initial presentation of stage III osteosarcoma with lung metastases depends on the resectability of the primary tumor and lung nodules, degree of necrosis of the primary tumor, and maybe the number of metastases. Overall survival prognosis is about 30%. [31]
The included cancer types are the ones causing most death as per data from the US in 2008. [1] Lung cancer, mainly to adrenal glands, brain, and bone [2] Breast cancer, mainly to bone, liver, lung and brain. [3] Colon cancer, mainly to liver. [4] Pancreatic cancer, mainly to liver and lungs. [5] Melanoma, mainly to brain [6]
The Pancoast tumor was first described by Hare in 1838 as a "tumor involving certain nerves". [2] It was not until 1924 that the tumor was described in further detail, when Henry Pancoast, a radiologist from Philadelphia, published an article in which he reported and studied many cases of apical chest tumors that all shared the same radiographic findings and associated clinical symptoms, such ...
Cannonball metastases are classically seen in renal cell carcinoma, [5] also seen in choriocarcinoma, endometrial cancer, [6] prostate cancer and some gastrointestinal malignancies. The presence of cannonball metastases is a hallmark of advanced systemic malignancy. Identification of these lesions often triggers search for primary tumor.
Continued cigarette smoking negatively impacts limited-stage small cell lung cancer survival. All clinicians and care providers should strongly encourage smoking cessation at the diagnosis of limited stage small cell lung cancer. Comparing to continued smokers, patients who quit at or after diagnosis lower the risk of death by 45%. [28]
