Induction of Invasive Transitional Cell Bladder Carcinoma in Immune Intact Human MUC1 Transgenic Mice: A Model for Immunotherapy Development
Published on: October 31, 2013
Summary
This study details the imaging and anatomical characteristics of mucinous adenocarcinoma of the urachus in two patients. Key features include midline abdominal masses and specific findings on roentgenography, cystography, and ultrasonography.
Area of Science:
- Urologic oncology
- Medical imaging
- Surgical pathology
Background:
- Mucinous adenocarcinoma of the urachus is a rare malignancy.
- Understanding its characteristic imaging and anatomical features is crucial for diagnosis and management.
Observation:
- Two cases of urachal adenocarcinoma presented with midline anterior abdominal masses.
- Roentgenographic findings included fine stippled calcification in one case.
- Cystography revealed an irregular filling defect in the bladder dome in another case.
Findings:
- Ultrasonography effectively delineated the mass's nature, size, and location.
- Combined imaging modalities aid in identifying urachal tumors.
- Anatomical localization in the supravesicular area is a consistent feature.
Implications:
- Early and accurate diagnosis of urachal adenocarcinoma can be improved with characteristic imaging findings.
- Definitive surgical management relies on precise pre-operative characterization.
- Further research into rare urachal malignancies is warranted.

02:18Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
02:21Cancers Originate from Somatic Mutations in a Single Cell
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...
02:59Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

01:22Ureters
The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...
01:20Disorders of the Male Reproductive System
Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
