The most frequent symptoms of transitional cell carcinoma are blood in the urine, painful urination, frequent urination and/or straining to urinate. This can look very similar to an infection of the urinary system.
Symptoms vary between individuals and can be dependent upon the stage of growth of the carcinoma. Presence of the carcinoma can lead to be asymptomatic blood in the urine (hematuria), Hematuria can be visible or detected microscopically. Visible hematuria is when urine appears red or brown and can be seen with the naked eye. Other symptoms are not specific. Other inflammatory conditions that affect the bladder and kidney can create similar symptoms. Early detection facilitates curing the disease. Other symptoms can involve:
- pain or burning on urination
- the sensation of not being able to completely empty the bladder
- the sensation of needing to urinate more often or more frequently than normal
These symptoms are general and also indicate less serious problems.
Signs and symptoms of TCC are entirely dependent on the location and extent of the cancer.
Diagnostic tests typically include complete blood tests, urinalysis, urine culture, X-rays of the abdomen and chest, and bladder imaging. The definitive diagnosis of bladder cancer will require a tissue biopsy and subsequent examination of the cells under the microscope.
Bladder cancer characteristically causes blood (redness) in the urine. This blood in the urine may be visible to the naked eye (gross/macroscopic hematuria) or detectable only by microscope (microscopic hematuria). Hematuria is the most common symptom in bladder cancer. It occurs in approximately 80–90% of the patients.
Other possible symptoms include pain during urination, frequent urination, or feeling the need to urinate without being able to do so. These signs and symptoms are not specific to bladder cancer, and are also caused by non-cancerous conditions, including prostate infections, over-active bladder and cystitis. There are many other causes of hematuria, such as bladder or ureteric stones, infection, kidney disease, kidney cancers and vascular malformations.
Patients with advanced disease refer pelvic or bony pain, lower-extremity edema, or flank pain.
Rarely a palpable mass can be detected on physical examination.
Invasive urothelial carcinoma is a type of transitional cell carcinoma or TCC and urothelial cell carcinoma or UCC. It is a type of cancer that develops in the urinary system: the kidney, urinary bladder, and accessory organs. It is the most common type of bladder cancer and cancer of the ureter, urethra, renal pelvis, the ureters, the bladder, and parts of the urethra and urachus.. It originates from tissue lining the inner surface of these hollow organs - transitional epithelium. The invading tumors can extend from the kidney collecting system to the bladder.
Carcinoma (from the Greek "karkinos", or "crab", and "-oma", "growth") is a type of cancer. A carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that generally arises from cells originating in the endodermal or ectodermal germ layer during embryogenesis.
Ureteral cancer is cancer of the ureters, muscular tubes that propel urine from the kidneys to the urinary bladder. It is also known as ureter cancer, renal pelvic cancer, and rarely ureteric cancer or uretal cancer. Cancer in this location is rare.
Ureteral cancer is usually transitional cell carcinoma. Transitional cell carcinoma is "a common cause of ureter cancer and other urinary (renal pelvic) tract cancers."
Transitional cell carcinoma (TCC) also urothelial carcinoma (UCC), is a type of cancer that typically occurs in the urinary system. It is the most common type of bladder cancer and cancer of the ureter, urethra, and urachus. It is the second most common type of kidney cancer, but accounts for only five to 10 percent of all primary renal malignant tumors.
TCC arises from the transitional epithelium, a tissue lining the inner surface of these hollow organs.
When the term "urothelial" is used, it specifically refers to a carcinoma of the urothelium, meaning a TCC of the urinary system.
Symptoms of ureteral cancer may include "blood in the urine (hematuria); diminished urine stream and straining to void (caused by urethral stricture); frequent urination and increased nighttime urination (nocturia); hardening of tissue in the perineum, labia, or penis; itching; incontinence; pain during or after sexual intercourse (dyspareunia); painful urination (dysuria); recurrent urinary tract infection; urethral discharge and swelling".
The most common signs and symptoms of kidney cancer are a mass in the abdomen and/or blood in the urine (or hematuria). Other symptoms may include tiredness, loss of appetite, weight loss, a high temperature and heavy sweating, and persistent pain in the abdomen. However, many of these symptoms can be caused by other conditions, and there may also be no signs or symptoms in a person with kidney cancer, especially in the early stages of the disease.
In addition to renal cell carcinoma and renal pelvis carcinoma, other, less common types of kidney cancer include:
- Squamous cell carcinoma
- Juxtaglomerular cell tumor (reninoma)
- Angiomyolipoma
- Bellini duct carcinoma
- Clear-cell sarcoma of the kidney
- Mesoblastic nephroma
- Wilms' tumor, usually is reported in children under the age of 5.
- Mixed epithelial stromal tumor
Rarely, some other types of cancer and potentially cancerous tumors that more usually originate elsewhere can originate in the kidneys. These include:
- Clear cell adenocarcinoma
- Transitional cell carcinoma
- Inverted papilloma
- Renal lymphoma
- Teratoma
- Carcinosarcoma
- Carcinoid tumor of the renal pelvis
Cancer in the kidney may also be secondary, the result of metastasis from a primary cancer elsewhere in the body.
It is not related urothelial carcinoma. It is in the "transitional cell" category of ovarian tumours which also includes malignant Brenner tumour and benign Brenner tumour.
These tumours do better than other types of epithelial tumours of the ovary.
Cytologic features of serous carcinoma are:
- Marked intragroup nuclear pleomorphism.
- Macronucleoli.
- "Knobby" group borders (in large groups).
- Hydropic vacuoles.
Symptoms of serous carcinoma may include:
- Discomfort/pain or bloating in abdomen
- Frequent urination
- Weight loss
Primary peritoneal cancer or carcinoma is also known as serous surface papillary carcinoma, primary peritoneal carcinoma, extra-ovarian serous carcinoma, primary serous papillary carcinoma, psammomacarcinoma. It was historically classified under "carcinoma of unknown primary" (CUP). Primary peritoneal cancer (PPC, or PPCa) is a cancer of the cells lining the peritoneum, or abdominal cavity.
Some studies indicate that up to 15% of serous ovarian cancers are thought to be actually primary peritoneal carcinomas in origin.
Histomorphological and molecular biological characteristics suggest that serous carcinomas, which include ovarian serous carcinoma, uterine serous carcinoma, Fallopian tube serous carcinoma, cervical serous carcinoma, and primary peritoneal serous carcinoma really represent one entity.
In pathology, serous carcinoma is an epithelial malignancy (carcinoma) that arises from the lining of a cavity that produces a serum-like fluid (a serous cavity).
Serous lined cavities include the peritoneum, pericardium and pleural space and tunica vaginalis.
Historically, medical practitioners expected a person to present with three findings. This classic triad is 1: haematuria, which is when there is blood present in the urine, 2: flank pain, which is pain on the side of the body between the hip and ribs, and 3: an abdominal mass, similar to bloating but larger. It is now known that this classic triad of symptoms only occurs in 10–15% of cases, and is usually indicative that the renal cell carcinoma (RCC) is in an advanced stage. Today, RCC is often asymptomatic (meaning few to no symptoms) and is generally detected incidentally when a person is being examined for other ailments.
Other signs and symptom may include haematuria; loin pain; abdominal mass; malaise, which is a general feeling of unwellness; weight loss and/or loss of appetite; anaemia resulting from depression of erythropoietin; erythrocytosis (increased production of red blood cells) due to increased erythropoietin secretion; varicocele, which is seen in males as an enlargement of the pampiniform plexus of veins draining the testis (more often the left testis) hypertension (high blood pressure) resulting from secretion of renin by the tumour; hypercalcemia, which is elevation of calcium levels in the blood; sleep disturbance or night sweats; recurrent fevers; and chronic fatigue.
Bladder cancer is any of several types of cancer arising from the tissues of the urinary bladder. It is a disease in which cells grow abnormally and have the potential to spread to other parts of the body. Symptoms include blood in the urine, pain with urination, and low back pain.
Risk factors for bladder cancer include smoking, family history, prior radiation therapy, frequent bladder infections, and exposure to certain chemicals. The most common type is transitional cell carcinoma. Other types include squamous cell carcinoma and adenocarcinoma. Diagnosis is typically by cystoscopy with tissue biopsies. Staging of the cancer is typically determined by medical imaging such as CT scan and bone scan.
Treatment depends on the stage of the cancer. It may include some combination of surgery, radiation therapy, chemotherapy, or immunotherapy. Surgical options may include transurethral resection, partial or complete removal of the bladder, or urinary diversion. Typical five-year survival rates in the United States are 77%.
Bladder cancer, as of 2015, affects about 3.4 million people with 430,000 new cases a year. Age of onset is most often between 65 and 85 years of age. Males are more often affected than females. In 2015 it resulted in 188,000 deaths.
PUNLMPs can lead to blood in the urine (hematuria) or may be asymptomatic.
Renal cell carcinoma (RCC) is a kidney cancer that originates in the lining of the proximal convoluted tubule, a part of the very small tubes in the kidney that transport primary urine. RCC is the most common type of kidney cancer in adults, responsible for approximately 90–95% of cases.
Initial treatment is most commonly either partial or complete removal of the affected kidney(s). Where the cancer has not metastasised (spread to other organs) or burrowed deeper into the tissues of the kidney, the 5-year survival rate is 65–90%, but this is lowered considerably when the cancer has spread.
The body is remarkably good at hiding the symptoms and as a result people with RCC often have advanced disease by the time it is discovered. The initial symptoms of RCC often include blood in the urine (occurring in 40% of affected persons at the time they first seek medical attention), flank pain (40%), a mass in the abdomen or flank (25%), weight loss (33%), fever (20%), high blood pressure (20%), night sweats and generally feeling unwell. When RCC metastasises, it most commonly spreads to the lymph nodes, lungs, liver, adrenal glands, brain or bones. Immunotherapy and targeted therapy have improved the outlook for metastatic RCC.
RCC is also associated with a number of paraneoplastic syndromes (PNS) which are conditions caused by either the hormones produced by the tumour or by the body's attack on the tumour and are present in about 20% of those with RCC. These syndromes most commonly affect tissues which have not been invaded by the cancer. The most common PNSs seen in people with RCC are: high blood calcium levels, polycythaemia (the opposite of anemia, due to an overproduction of the hormone erythropoietin), thrombocytosis (too many platelets in the blood, leading to an increased tendency for blood clotting and bleeds) and secondary amyloidosis.
In urologic pathology, PUNLMP, short for papillary urothelial neoplasm of low malignant potential, is an exophytic (outward growing), (microscopically) nipple-shaped (or papillary) pre-malignant growth of the lining of the upper genitourinary tract (the urothelium), which includes the renal pelvis, ureters, urinary bladder and part of the urethra.
"PUNLMP" is pronounced "pun"-"lump", like the words "pun" and "lump".
As their name suggests, PUNLMPs are neoplasms, i.e. clonal cellular proliferations, that are thought to have a low probability of developing into urothelial cancer, i.e. a malignancy such as bladder cancer.
The lesion is found in patients who present typically with abnormal or postmenopausal bleeding or discharge. Such bleeding is followed by further evaluation leading to a tissue diagnosis, usually done by a dilatation and curettage (D&C). A work-up to follow would look for metastasis using imaging technology including sonography and MRI. The median age at diagnosis in a large study was 66 years. Histologically the lesion may coexist with classical endometrial cancer.
Symptoms that may be caused by urethral cancer include:
Bleeding from the urethra or blood in the urine,
Weak or interrupted flow of urine,
Urination occurs often, painful urination, inability to pass urine,
A lump or thickness in the perineum or penis,
Discharge from the urethra,
Enlarged lymph nodes or pain in the groin or vaginal area.
Urachal cancer can exist for some years without any symptoms. The most frequent initial symptom is haematuria which occurs when the urachal tumour has penetrated the bladder wall, but mucinuria (mucin in the urine), local pain or swelling, recurrent local or urinary tract infections and umbilical discharge can (but is not always) be seen.
Prognosis and treatment is the same as for the most common type of ovarian cancer, which is epithelial ovarian cancer.
The median survival of primary peritoneal carcinomas is usually shorter by 2–6 months time when compared with serous ovarian cancer. Studies show median survival varies between 11.3–17.8 months. One study reported 19-40 month median survival (95% CI) with a 5-year survival of 26.5%.
Elevated albumin levels have been associated with a more favorable prognosis.
