Treatment Resistant Cancers02:56

Treatment Resistant Cancers

3.4K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Tumor Progression02:07

Tumor Progression

6.7K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Rous Sarcoma Virus (RSV) and Cancer

5.6K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Varicose Veins II: Diagnostic Studies and Interprofessional Care01:26

Varicose Veins II: Diagnostic Studies and Interprofessional Care

53
Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Esophageal Varices-II: Clinical Features and Management01:28

Esophageal Varices-II: Clinical Features and Management

188
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Tumor Immunotherapy01:27

Tumor Immunotherapy

773
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Area of Science:

  • Oncology
  • Radiology
  • Pathology

Background:

  • Primary leiomyosarcoma of the inferior vena cava (IVC) is a rare malignancy.
  • It is associated with a poor prognosis due to delayed diagnosis.
  • Nonspecific symptoms often hinder early detection.

  • To review the pathology of IVC leiomyosarcoma.
  • To outline clinical and imaging features.
  • To discuss management strategies.

Main Methods:

  • Review of existing literature on IVC leiomyosarcoma.
  • Analysis of characteristic imaging findings across ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI).
  • Discussion of treatment modalities.

Main Results:

  • Key imaging findings include caval lumen obstruction, IVC dilation, heterogeneous tumor enhancement, and collateral circulation.
  • Surgical resection is the primary treatment.
  • Chemotherapy and radiation are potential adjunct therapies.

Conclusions:

  • IVC leiomyosarcoma requires prompt diagnosis through characteristic imaging features.
  • Multidisciplinary management involving surgery, and potentially chemotherapy/radiation, is essential.
  • Understanding these aspects improves patient outcomes.
