A - C
Abdominal CT scan A series of x-ray pictures taken of the abdomen by a machine that encircles the body like a giant tube. Computers are then used to generate cross-sectional images of the inside of the body.
Abscess A pus-filled cavity.
Adenoma A benign (non-cancerous) tumor made up of cells that form glands (collections of cells surrounding an empty space.)
Adjuvant chemotherapy Chemotherapy given to patients after their cancers have been surgically removed. It is a secondary treatment given to supplement surgical treatment. (see Neoadjuvant chemotherapy)
Anaplastic cancer Cancer cells that divide rapidly and revert to an undifferentiated form with no orientation to one another
Anemia A condition characterized by a deficiency in red blood cells. This can lead to fatigue, among other symptoms.
Angiography A radiographic technique used to visualize blood vessels. A contrast medium (a dye) is usually injected into the vessels to make them appear white on the x-rays.
Anorexia A condition marked by a diminished appetite and aversion to food. Often results in physical signs of wasting.
Antibody Any of a large number of proteins that are produced normally by specialized B cells after stimulation by an antigen and act specifically against the antigen in an immune response
Antigen Usually a protein or carbohydrate substance capable of stimulating an immune response
Ascites The collection of excess amounts of fluid in the abdominal cavity (belly). It often is a sign that the cancer has spread to either the liver or the portal vein that goes to the liver. If normal liver function is affected, a complex set of biochemical checks and balances is disrupted and abnormal amounts of fluid are retained.
Assay Analysis to determine the presence, absence, or quantity of one or more components
BCG (Bacille Calmette-Guerin) Intravesical drug used to treat superficial bladder cancers.
Benign tumor A tumor which is non-cancerous. These generally grow slowly and do not invade adjacent organs or spread (metastasize) beyond the bladder
Biomarker A distinctive usually biochemical indicator of a biological or geochemical process or event
Biopsy The removal and microscopic examination of a tissue sample.
Cachexia A dramatic weight loss and general wasting that occurs during chronic disease.
Cancer A malignant tumor. It has the potential of invading into the adjacent tissues, spreading to other organs and may eventually lead to the patient's death.
Carboplatin Generic name for chemotherapy drug Paraplatin(r)
Carcinogen A cancer-causing agent.
Carcinoma A malignant (cancerous) new growth. These tumors infiltrate into surrounding tissues and, if untreated, will spread to other organs, and may eventually lead to the patient's death.
Catheter A small, flexible tube inserted into the body to inject or suck out fluids.
Chemotherapy The treatment of a cancer by chemicals. For bladder cancer these include: cisplatin (Platinol(r)), doxorubicin, cyclophosphamide (Cytoxan(r)), methotrexate, vinblastine, gemcitabine and paclitaxel (Taxol(r)), and others.
Cisplatin Generic name for chemotherapy drug Platinol(r)
Cohort A group of individuals who share a common characteristic.
e.g. a group of individuals entered in a prospective study
Colonoscopy Visual examination of the inside of the colon (large intestine) by means of a colonoscope (elongated flexible fiberoptic endoscope).
Computed tomography (CT) tcan A series of x-ray pictures taken by a machine that encircles the body like a giant tube. Computers are then used to generate cross-sectional images of the inside of the body.
Contrast agent (or medium) A dye, taken by mouth or injected, that is sometimes used during x-ray examinations to highlight areas that otherwise might not be seen.
Cyclophosphamide Generic name for chemotherapy drug Cytoxan(r)
Cystectomy Surgical removal of the bladder
Cystoprostatectomy Surgical removal of the bladder and prostate
Cystoscopy Visual examination of the inside of the bladder by means of a cystoscope (Instrument that is passed through the urethra and allows visualization and biopsy of the bladder).
Cytoxan(r) Trade / brand name for chemotherapy drug cyclophosphamide
D - E
Diaphragm A dome shaped muscle that separates the lungs and heart from the abdomen. This muscle assists in breathing.
Differentiate To develop specialized form, character, or function differing from that of surrounding cytoplasm, cells, or tissue from the original type
Disseminated Widely dispersed in a tissue, organ, or the entire body
DNA (deoxyribonucleic acid) The part of every cell that carries all genetic information.
Dysplasia A precancerous condition in which cells which are very similar to cancer cells grow in an organ but have not yet acquired the ability to invade into tissue or metastasize (spread to areas distant from where they started). This is a stage which can be cured.
-ectomy Surgical removal of a structure or part of a structure. For example, cystectomy is the surgical removal of the bladder
Endoscopy A procedure whereby a flexible fiber-optic tube is inserted into the esophagus, stomach or small intestine through the mouth (upper endoscopy) or into the large intestine through the anus (lower endoscopy) to look for abnormalities.
Exophytic growing outward; spreading externally or on the surface epithelium of where the growth originated
Gemzar Trade / brand name for chemotherapy drug gemcitabine
Genitourinary Of or relating to organs of urination and reproduction, including the bladder, urethra, ureter, kidney, prostate and testes
Granulomatous inflammation A mass or nodule of chronically inflammed tissue with granulation that is usually associated with an infective process. This is commonly seen in the bladder after intravesical therapy with BCG.
Hemorrhagic A copious discharge of blood from the blood vessels
Immunogenic Relating to or producing an immune response
in situ Term used to indicate that cancerous cells are present in the lining of an organ but have not spread to the "meat of the tissue.
Intravenous pyelogram (IVP) A conventional x-ray test using dye to examine the kidneys, ureters, and bladder. This x-ray will look at the collecting system of the kidneys to determine the presence of an abnormality.
Laparoscopy A technique that surgeons can use to visualize and even biopsy (take tissue samples of) organs inside of the abdomen without making large incisions. Very small incisions are made in the belly and small tubes (called trocars) are then inserted. Gas is pumped in through one of the tubes to create enough space to work in. The surgeon inserts a small camera through one of the tubes and examines the lining and contents of the abdominal cavity by looking at the projected image on the television screen. With specially designed laparascopic instruments, biopsies and fluid samples can be taken for examination.
Loco-regional cancer A primary cancer that has spread to regional lymph nodes and/or resectable (removable) tissues. Removable tissues include some lymph nodes that are routinely removed in some surgical treatments for cancer.
Low Malignant potential (LMP) tumor Low malignant potential (LMP) tumors are a borderline form of cancer that has a lower likelihood of eventual spread and invasion. This is a gray zone. A pathologist can distinguish a LMP tumor that does not tend to progress from other superficial bladder cancers that are more likely to eventually spread and progress.
Llymph nodes Normal, round, raisin to grape-sized collections of lymphocytes (white blood cells) found throughout the body. Lymph nodes are connected to each other by lymphatic vessels. They normally help fight infection, but also are one of the first sites to which cancers spread. In general, the spread of cancer to lymph nodes portends a worse prognosis for the patient.
M - O
Magnetic resonance imaging (MRI) A painless method for taking pictures of internal organs. A tube-like machine with a powerful magnet generates images of the inside of the body.
Malignant tumor A cancer that has the potential of invading nearby tissues, spreading to other organs (metastasizing) and possibly leading to the patient's death.
Metaplasia In smokers, this lining is replaced by a cell type normally found in the mouth (squamous epithelium), and is called "squamous metaplasia. In the bladder, the normal lining is transitional epithelium, but in patients with recurrent infections, indwelling catheters or chronic irritation, the esophagus lining may be replaced with a cell type normally found in the intestines (intestinal metaplasia).
Metastatic cancer A cancer that has spread from one organ to another. In general, cancers that have metastasized are generally not treated surgically, but instead are treated with chemotherapy and/or radiation therapy.
Mitomycin C An intravesical chemotherapy drug
Mutation An alteration in the DNA of a cell.
Necrosis Usually localized death of living tissue
Neoadjuvant A new method that assists in the prevention or cure of disease
Neoadjuvant chemo and radiation therapy Chemotherapy and radiation therapy given to patients before surgery. Some centers feel that the use of neoadjuvant therapy improves local and regional control of disease and that it may make more patients surgical candidates.
Neoplasm An abnormal new growth of tissue that grows more rapidly than normal cells and will continue to grow if not treated. These growths will compete with normal cells for nutrients. This is a general term that can refer to benign or malignant growths. It is almost a synonym for the word tumor, which means a mass or growth.
Omentum A fold of peritoneum extending from the stomach to adjacent abdominal organs
Oncologist A medical doctor who specializes in the treatment of tumors.
-ostomy A surgically created opening in an organ that can also be referred to as an anastomosis.
P - S
Paclitaxel Generic name for chemotherapy drug Taxol(r)
Palliative Any treatment that reduces the severity of a disease or its symptoms.
Papillary Branch-like arrangement of the tumor cells.
Paraplatin(r) Trade / brand name for chemotherapy drug carboplatin
Pathologist A medical doctor specially trained to study disease processes.
Peritoneum The serous membrane lining the walls of the abdominal and pelvic cavities and contained organs
Platinol(r) Trade / brand name for chemotherapy drug cisplatin
Pleomorphic Able to assume different forms
Primary cancer A cancer found in the organ it started in. A primary cancer of the bladder is one that started in the bladder as opposed to a cancer that started somewhere else and only later spread to the bladder.
Prognosis A forecast for the probable outcome of a disease based on the experience of large numbers of other patients with similar stage disease. Importantly, making a prognosis is not an exact science. Some patients with poor prognosis beat the odds and live longer than anyone would have predicted.
Radiation therapy The use of high-energy waves similar to x-rays to treat a cancer. Radiation therapy is usually used to treat a local area of disease and often is given in combination with chemotherapy.
Resectable Able to be removed surgically.
Sarcoma A malignant tumor that mimics connective tissues (bone, cartilage, muscle) under the microscope.
Sepsis An infection of the blood.
Small intestine A long (20 foot) tube that stretches from the stomach to the large intestine. It helps absorb nutrients from food as the food is transported to the large intestine. There are three sections: the duodenum, the jejunum and the ileum.
Spectrometry an instrument used for measuring wavelengths of light
Spleen A maroon, rounded organ in the upper left part of the abdomen, near the tail of the pancreas. This organ is part of your immune system and filters the lymph and blood in your body.
Squamous cell A flat, scale-like cell.
Stent A slender hollow tube inserted into the body to relieve a blockage. For example, bladder cancers can narrow the ureter. This can block the flow of urine. In these cases the flow of urine can be reestablished by placing a stent into the ureter, through the area of blockage.
T - Z
Taxol(r) Trade / brand name for chemotherapy drug paclitaxel
Thrombophlebitis An inflammation of the veins accompanied by thrombus formation. It is sometimes referred to as Trousseau's sign.
Thrombus A clot within the cardiovascular system. It may occlude (block) the vessel or may be attached to the wall of the vessel without blocking the blood flow.
Tumor This term simply refers to a mass or neoplasm. For example, a collection of pus is a tumor. This is a general term that can refer to benign or malignant growths.
Ultrasound A painless procedure in which high frequency sound waves are used to generate pictures of the inside of the body.
Unresectable Unable to be surgically removed.
Urologist A medical doctor who specializes in the management and surgery of diseases of the genitourinary tract.
Vaccine therapy This is a new type of treatment, largely still experimental. It is a medication made of killed or weakened cells, organisms or manufactured materials, which is used to boost the body's immune system. Ideally, this will allow the body to fight and kill the cancer cells more effectively. Vaccines include whole killed cancer cells or specific proteins from the cancer.
