Pseudomyxoma peritonei (PMP) is a clinical condition caused by cancerous cells (mucinous adenocarcinoma) that produce abundant mucin or gelatinous ascites. [1] The tumors cause fibrosis of tissues and impede digestion or organ function, and if left untreated, the tumors and mucin they produce will fill the abdominal cavity.
In medicine, proton therapy, or proton radiotherapy, is a type of particle therapy that uses a beam of protons to irradiate diseased tissue, most often to treat cancer.The chief advantage of proton therapy over other types of external beam radiotherapy is that the dose of protons is deposited over a narrow range of depth; hence in minimal entry, exit, or scattered radiation dose to healthy ...
Severe bladder tumors often shed cells into the urine; these can be detected by urine cytology, where cells are collected from a urine sample, and viewed under a microscope. [6] [7] Cytology can detect around two thirds of high-grade tumors, but detects just 1 in 8 low-grade tumors. [8]
Esophageal cancer (lower part) as a result of Barrettʼs esophagus. Male predominance is particularly strong in this type of esophageal cancer, which occurs about 7 to 10 times more frequently in men. [25] This imbalance may be related to the characteristics and interactions of other known risk factors, including acid reflux and obesity. [25]
The principal objective is to remove the esophagus, a part of the gastrointestinal tract. This procedure is usually done for patients with esophageal cancer. It is normally done when esophageal cancer is detected early, before it has spread to other parts of the body. Esophagectomy of early-stage cancer represents the best chance of a cure.
The strip biopsy method for endoscopic mucosal resection of esophageal cancer is performed with a double-channel endoscope equipped with grasping forceps and snare. After marking the lesion border with an electric coagulator, saline is injected into the submucosa below the lesion to separate the lesion from the muscle layer and to force its ...
A partial cystectomy involves removal of only a portion of the bladder and is performed for some benign and malignant tumors localized to the bladder. [9] Individuals that may be candidates for partial cystectomy include those with single tumors located near the dome, or top, of the bladder, tumors that do not invade the muscle of the bladder, tumors located within bladder diverticulum, or ...
G (1–4): the grade of the cancer cells (i.e. they are "low grade" if they appear similar to normal cells, and "high grade" if they appear poorly differentiated) S (0–3): elevation of serum tumor markers; R (0–2): the completeness of the operation (resection-boundaries free of cancer cells or not) Pn (0–1): invasion into adjunct nerves
