The procedure is common in the treatment of Stage I and II non-seminomatous germ cell tumors. [2] In seminomas, another form of testicular cancer, radiation therapy is generally preferred to the invasive RPLND procedure. [4] Whether RPLND is needed after orchiectomy depends on the type of tumor and its stage. RPLND may be performed to remove ...
Usually therapeutic levels of radiation are delivered to the tumor bed while the area is exposed during surgery. IORT is typically a component in the multidisciplinary treatment of locally advanced and recurrent cancer, in combination with external beam radiation, surgery, and chemotherapy.

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:
The analysis of tumor markers also helps in staging. [12] The preferred treatment for most forms of stage 1 seminoma is active surveillance. Stage 1 seminoma is characterized by the absence of clinical evidence of metastasis. Active surveillance consists of periodic history and physical examinations, tumor marker analysis, and radiographic imaging.
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.
Gardner syndrome is an autosomal dominant form of polyposis characterized by the presence of multiple polyps in the colon together with tumors outside the colon. [3] The extracolonic tumors may include osteomas of the skull, thyroid cancer , epidermoid cysts , fibromas , [ 4 ] as well as the occurrence of desmoid tumors in approximately 15% of ...
The TNM Classification of Malignant Tumors (TNM) is a globally recognised standard for classifying the anatomical extent of the spread of malignant tumours (cancer). It has gained wide international acceptance for many solid tumor cancers, but is not applicable to leukaemia or tumors of the central nervous system. Most common tumors have their ...
