Muscle Invasive Bladder Cancer (MIBC) Diagnosis and Treatment

Treatment options for people with MIBC are therefore directed at both the cancer in the bladder and at possible unsuspected spread to lymph nodes. The options considered are chemotherapy, radical cystectomy and radical radiotherapy.

What stage is Mibc?

Muscle invasive bladder cancer is a serious and more advanced stage of bladder cancer. MIBC is when the cancer has grown far into the wall of the bladder (Stages T2 and beyond). For patients with MIBC, the overall prognosis (how the disease may progress) is dependent on stage and treatment.

How is Mibc diagnosed?

Diagnosis of MIBC

Urine cytology is used to check for abnormal cells within the urine. Blood tests are done to get a comprehensive metabolic panel (CMP), including kidney and liver function tests. X-ray, CT scan, or MRI is done to get images of the affected area.

What does Mibc mean?

Muscle invasive bladder cancer (MIBC) is a cancer that spreads into the detrusor muscle of the bladder. The detrusor muscle is the thick muscle deep in the bladder wall. This cancer is more likely to spread to other parts of the body.

Where does bladder cancer usually metastasize to?

Lymph nodes, bones, lung, liver, and peritoneum are the most common sites of metastasis from bladder cancer. Tumors in a more advanced T category and those with atypical histologic features metastasize earlier. Tumors with atypical histologic features also have a higher frequency of peritoneal metastasis.

How long can you live after cystectomy?

Patients in group 1 achieved a progression-free 5-year survival rate of 77% and an overall survival rate of 63% after 5 years. In group 2 patients achieved a progression-free survival rate of 51% after 5 years and an overall survival rate of 50%.

What size bladder tumor is considered large?

First, there is no common agreement regarding what size a bladder tumor constitutes a large tumor. In the literature, a large tumor has been variously defined as one with a total resected weight > 50 g, a weight ?15 g, and a diameter > 5 cm [2-4].

Can Mibc be cured?

Spread to the lymph nodes usually reduces the chance of cure considerably. Treatment options for people with MIBC are therefore directed at both the cancer in the bladder and at possible unsuspected spread to lymph nodes. The options considered are chemotherapy, radical cystectomy and radical radiotherapy.

How aggressive is urothelial carcinoma?

Does size of bladder tumor matter?

CONCLUSIONS: Larger tumor size (>5 cm) is associated with greater length of stay, reoperation, readmission, and death following TURBT. Patients should be counseled appropriately and likely warrant vigilant observation prior to and following hospital discharge.

What is bladder detrusor muscle?

Structure and Function

The wall of the bladder is comprised of smooth muscle fibers oriented in multiple different directions. These smooth muscle fibers are collectively known as the detrusor muscle. This interwoven orientation provides the bladder with the ability to stretch in response to the presence of urine.

What is a cystectomy procedure?

Cystectomy (sis-TEK-tuh-me) is a surgery to remove the urinary bladder. In men, removing the entire bladder (radical cystectomy) typically includes removal of the prostate and seminal vesicles. In women, radical cystectomy also involves removal of the uterus, ovaries and part of the vagina.

Does bladder cancer spread fast?

It is an early stage cancer but is always high grade. This means it can grow quickly and might spread. If you have bladder carcinoma in situ your doctor will start treatment straight away.

What percent of bladder cancer is metastatic?

Metastatic disease, which accounts for only 5% of cases in the US, has a 5-year survival under 5%. The greatest risk factor for the urothelial subtype, which comprises 90% of all cases, is tobacco smoking. Smoking accounts for 5065% of all bladder cancer cases and increases the risk of the disease by 3-fold.

Bladder cancer can also spread to another part of the body. This is secondary cancer or metastasis. The places it’s most likely to spread to are your: lymph nodes in the pelvis and tummy (abdomen)

How do you pee after bladder removal?

A tube made from a piece of your small intestine funnels your pee from the kidneys directly to the outside of your body. A surgical hole on your belly lets the open end of the small intestine drain the urine into a small, flat pouch. You’ll have to empty it several times a day. Neobladder.

Listen to pronunciation. (hy grayd) A term used to describe cells and tissue that look abnormal under a microscope. High-grade cancer cells tend to grow and spread more quickly than low-grade cancer cells.

Do you need chemo after bladder removal?

Some patients get chemo after surgery to kill any cancer cells left after surgery that are too small to see. Chemo given after cystectomy may help patients stay cancer-free longer, but so far it’s not clear if it helps them live longer. If cancer is found in nearby lymph nodes, radiation may be needed after surgery.

Is bladder wall thickening serious?

A thickening of the bladder wall can be a sign of several medical conditions. It’s usually accompanied by other symptoms, too. Many of these conditions are easily treatable with an early diagnosis. It’s important to report any changes in your urinary habits to your doctor.

How does neoadjuvant chemotherapy work?

Neoadjuvant chemotherapy is chemotherapy that a person with cancer receives before their primary course of treatment. The aim is to shrink a cancerous tumor using drugs before moving onto other treatments, such as surgery. Neoadjuvant chemotherapy helps doctors target cancerous growths more easily at a later stage.

What stage is high grade urothelial carcinoma?

Grade 3. The cancer cells look very abnormal. They are called high grade or poorly differentiated. They grow more quickly and are more likely to come back after treatment or spread into the deeper (muscle) layer of the bladder.

What is invasive high grade urothelial carcinoma?

High-grade tumors have an aggressive appearance under a microscope and are assumed invasive in the kidney or ureter. In the bladder, a thick bladder muscle (called the detrusor) acts as a barrier to confine invasive cancers but in the kidney and ureter, this muscle does not exist.

Does the size of a tumor determine the stage?

Tumor Size and Staging

Tumor size is strongly related to prognosis (chances for survival). In general, the smaller the tumor, the better the prognosis tends to be [12]. Tumor size is part of breast cancer staging. In the TNM staging system, a T followed by a number shows the size of the tumor.

Low-risk bladder cancer patients with tumors smaller than 1 cm could be classified separately as a very-low-risk group, according to a new analysis.

What is a muscular bladder?

The urinary bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear. Urine is made in the kidneys and travels down two tubes called ureters to the bladder. The bladder stores urine, allowing urination to be infrequent and controlled.

Lymph nodes, bones, lung, liver, and peritoneum are the most common sites of metastasis from bladder cancer. Tumors in a more advanced T category and those with atypical histologic features metastasize earlier. Tumors with atypical histologic features also have a higher frequency of peritoneal metastasis.

Where does bladder cancer usually spread to first?

Bladder cancer can spread this way. If it does, it usually first spreads to the lymph nodes in the pelvis around the bladder (called perivesicular lymph nodes). From there, it can spread to lymph nodes that are close to major blood vessels that run into the leg and pelvis.
