Prognosis and treatment is the same as for the most common type of ovarian cancer, which is epithelial ovarian cancer. [6] [7] The median survival of primary peritoneal carcinomas is usually shorter by 2–6 months time when compared with serous ovarian cancer. Studies show median survival varies between 11.3 and 17.8 months.
For these localized forms of DDL, perioperative radiotherapy following National Comprehensive Cancer Network guidelines may also be considered. [8] Retroperitoneal DDL is the most common, surgically unaccessible and serious form of DDL: it has a recurrence rate of 66% and a five-year overall survival rate of 54%. [31]
Testicular cancer metastasizes in a predictable pattern, and lymph nodes in the retroperitoneum are typically the first place it lands. [1] [2] By examining the removed lymphatic tissue, a pathologist can determine whether the disease has spread. If no malignant tissue is found, the cancer can be labeled Stage I, limited to the testicle. [3]
Conventional CT and MRI should be performed with cuts of 10 mm or less in slice thickness contiguously. Spiral CT should be performed using a 5 mm contiguous reconstruction algorithm. This applies to tumors of the chest, abdomen and pelvis. Head and neck tumors and those of extremities usually require specific protocols.
Retroperitoneal fibrosis; Retroperitoneal lymph node dissection; It is also possible to have a neoplasm in this area, more commonly a metastasis; or very rarely a primary neoplasm. The most common type is a sarcoma followed by lymphoma, extragonadal germ cell tumor, and gastrointestinal stromal tumor/GIST. [9] Examples of tumors include:
Multiple endocrine neoplasia (abbreviated MEN) is a condition which encompasses several distinct syndromes featuring tumors of endocrine glands, each with its own characteristic pattern. In some cases, the tumors are malignant, in others, benign. Benign or malignant tumors of nonendocrine tissues occur as components of some of these tumor ...
male sex, age [1] Retroperitoneal fibrosis or Ormond's disease is a disease featuring the proliferation of fibrous tissue ( fibrosis ) in the retroperitoneum , the compartment of the body containing the kidneys , aorta , renal tract , and various other structures.
A Klatskin tumor (or hilar cholangiocarcinoma) is a cholangiocarcinoma (cancer of the biliary tree) occurring at the confluence of the right and left hepatic bile ducts. The disease was named after Gerald Klatskin , who in 1965 described 15 cases and found some characteristics for this type of cholangiocarcinoma.
