  2. Germ cell tumor - Wikipedia

    en.wikipedia.org/wiki/Germ_cell_tumor

    The 1997 International Germ Cell Consensus Classification [17] is a tool for estimating the risk of relapse after treatment of malignant germ-cell tumor. A small study of ovarian tumors in girls [18] reports a correlation between cystic and benign tumors, and conversely, solid and malignant tumors. Because the cystic extent of a tumor can be ...

  3. Mediastinal germ cell tumor - Wikipedia

    en.wikipedia.org/wiki/Mediastinal_germ_cell_tumor

    Most mediastinal malignant tumors are large and cause symptoms by compressing or invading adjacent structures, including the lungs, pleura, pericardium, and chest wall. Seminomas grow relatively slowly and can become very large before causing symptoms. Tumors 20 to 30 cm in diameter can exist with minimal symptomatology.

  4. Cancer of unknown primary origin - Wikipedia

    Germ cell tumors often carry abnormality of chromosome 12, which if identified, directs treatment for metastatic germ cell tumors. [medical citation needed] No method is standard for all forms of CUP, but chemotherapy, radiation therapy, hormone therapy, and surgery may be used alone or in combination to treat patients who have CUP. Even when ...

    Relative incidences of testicular tumors, showing seminoma at bottom left. [2] A seminoma is a germ cell tumor of the testicle or, more rarely, the mediastinum or other extra-gonadal locations. It is a malignant neoplasm and is one of the most treatable and curable cancers, with a survival rate above 95% if discovered in early stages.

  6. Small-cell carcinoma - Wikipedia

    en.wikipedia.org/wiki/Small-cell_carcinoma

    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 ...

    en.wikipedia.org/wiki/Paraneoplastic_syndrome

    Oncology. Frequency. Rare [1] A paraneoplastic syndrome is a syndrome (a set of signs and symptoms) that is the consequence of a tumor in the body (usually a cancerous one). [1] It is specifically due to the production of chemical signaling molecules (such as hormones or cytokines) by tumor cells or by an immune response against the tumor. [2]

  8. Hamartoma - Wikipedia

    en.wikipedia.org/wiki/Hamartoma

    This is a syndrome that predisposes people to cancer and increases the risk of developing cancer in many different tissues, but particularly in the endometrium, thyroid, and breast. It is inherited autosomally dominantly, with a germ-line mutation of the PTEN tumor suppressor gene present in about 80% of patients. [26]

  9. Thymic carcinoma - Wikipedia

    en.wikipedia.org/wiki/Thymic_carcinoma

    Early-stage thymic carcinoma is generally asymptomatic, and the development of symptoms is indicative of an advanced stage cancer. [3] Signs and symptoms are non-specific and include chest pain, persistent cough, and difficulty breathing, which are related to progressive tumor compression of anterior chest wall structures. [4]
