Unbeatable Advantages of Robotic Prostate Cancer Surgery

A boon for Prostate Cancer patients - Advanced Robotic Prostate Surgery is now preferred choice for Prostate Cancer patients due to following Unmatched advantages

• Minimal Bleeding
• Much quicker recovery
• Reduced hospital stay
• Lesser pain killer requirements
• Lower blood transfusion rates
• Improved preservation of physical appearance
• Three (3) D vision enables surgeon to perform Prostate excision with Cancer
• Control without risk of Post Surgery Continence (control over urinary and
• fecal discharge) and causing Impotency

What is Da Vinci master slave Robotic System?

Da Vinci master slave robotic system is used to completely eradicate cancer with minimal side effects for treating Prostate Cancer. Through this system a minimally invasive robot assisted radical prostatectomy technique has been developed in which doctors evolved a unique sequence of surgical steps.

The Da Vinci is a sophisticated master-slave robot that incorporates 3-D high definition visualization, scaling of movement, and wristed instrumentation. The operations with the Da Vinci System are performed with no direct mechanical connection between the surgeon and the patient. The surgeon is working a few feet away from the operating table, while seated at a computer console with a three-dimensional view of the operating field.

 How it is  performed ?

Robotic Prostatectomy, also known as Robotic surgery for prostate cancer or da Vinci Prostatectomy is a minimally invasive surgery that is now the preferred approach for removal of the prostate in those diagnosed with organ-confined prostate cancer. The da Vinci Prostatectomy may be the most effective, least invasive prostate surgery performed today. Though any diagnosis of cancer can be traumatic, the good news is that if your doctor recommends prostate surgery, the cancer was probably caught early. And, with da Vinci Prostatectomy, the likelihood of a complete recovery from prostate cancer without long-term side effects is, for most patients, better than it has ever been.

The operation is performed using the daVinci Surgical system and 3-D endoscopic and wristed instruments inserted through 5-6 small incisions across the mid-abdomen

UnbeatableAdvantages of Robotic Prostate Surgery over the Conventional Prostate Cancer Surgery
1) Usually in conventional approach, surgeons make decisions using tactile and visual cues to identify a phenomenon, which is actually microscopic which is likely to damage nerves or to leave cancer behind. In the Advanced Robotic Technique (ART) surgeons uses a sophisticated mastr slave robot that incorporates 3-D high definition vision, scaling of movement and wristed instrumentation that gives him the ability to perform Prostate excision with minimal risk of leaving the cancer behind and also minimal bleeding and post operative risk of incontinence and impotence.

2) Neither clinical nor imaging tests are sensitive enough to capture a tumour at T3 stage where it has become locally advanced and a risk for spreading to other body parts. Sometimes it is difficult for surgeons to find a precise plane between the cancer and urinary sphincter or the nerves and err on the side of cancer safety leading to incontinence or Impotence Da vinci robot system minimizes side effects thereby greater control for the patient over urinary discharge i.e. continence and return to normal sexual function after the surgery.

Laser Prostate Surgery in India : Cost Estimate for Laser Prostate Surgery is $5000 US Dollars

Green Light PVP Surgery of Prostate in India

Thislasertreatment of the prostate is a new, minimally invasive surgical technique for treating Benign Prostatic Hyperplasia (BPH), or enlargement of the prostate. Greenlight HPS utilizes a specially designed laser light source and fiber optic delivery system developed by Laserscope in concert with researchers from the Mayo Clinic and other institutions around the world. The PVP procedure combines the immediate symptom relief and the dramatic flow rate improvements of the current "gold standard" procedure (called TURP or Trans-Urethral Resection of the Prostate) with minimal side effects, fast operative and recovery times, and usually no need for a catheter after surgery.

No other BPH treatment option has been shown to clinically provide such dramatic and immediate symptom relief while concurrently providing significant uroflow results and minimal, if any, side-effects. The PVP technique is a fast, outpatient treatment that will satisfy both the subjective (symptom relief) and objective (uroflowometry results) outcomes of a successful BPH treatment. Other minimally invasive BPH treatment options (such as TUMT, microwave, TUNA, thermotherapy) require compromises to be made by the patient and/or the physician. With PVP, there are no compromises, patient's symptoms are drastically reduced and flow rates are significantly improved.

Green Light PVPSurgery of Prostate 

The PVP (Photoselective Vaporization of the Prostate) Procedure that uses the Green Light PV laser system offers a unique and simple solution to Benign Prostatic Hypertrophy (BPH) because it combines the effectiveness of TURP, the surgical "gold standard" with the safety, comfort and ease of a minimally invasive treatment.

The PVP Procedure uses a very high powered laser to immediately vaporize and precisely remove enlarged prostate tissue. PVP (Photo-Selective Vaporization of the Prostate) is performed with the KTP laser by Laserscope (Greenlight PVP). This laser treatment of the prostate is a new, minimally invasive surgical technique for treating Benign Prostatic Hyperplasia (BPH), or enlargement of the prostate. 

Greenlight PV utilizes a specially designed laser light source and fiber optic delivery system.

The PVP procedure combines the immediate symptom relief and the dramatic flow rate improvements of the current "gold standard" procedure (called TURP or Trans-Urethral Resection of the Prostate) with minimal side effects, fast operative and recovery times, and usually no need for a catheter after surgery.

Other minimally invasive BPH treatment options (such as TUMT, microwave, TUNA, thermotherapy) require compromises to be made by the patient and/or the physician. With PVP, there are no compromises, patient's symptoms are drastically reduced and flow rates are significantly improved.

The PVP procedure is performed in an outpatient setting, typically a hospital or surgical center, with average operative times normally less than 60 minutes. The GreenLight PV surgical laser system, which is used to perform the KTP laser PVP treatment, delivers laser light pulses through a specially designed fiber optic delivery device that is inserted through a standard cystoscope. The light pulses are directed towards the prostate tissue. The laser quickly vaporizes and removes the prostatic obstruction without significant bleeding.

Once the procedure is completed, patients have immediate post-operative symptom relief and dramatic improvements in symptoms, urinary flow rates, and bladder emptying.

Most Advanced Throat Cancer Treatment and Surgery in India

Throat Cancer Treatment

Throat cancer is the cancer of the throat; it is a type of head and neck cancer.  The throat (pharynx) is a 5-inch-long tube that runs from your nose to your neck. The throat and the voice box are the two main places throat cancer forms.

Throat Cancer, which is usually caused by excessive use of tobacco or alcohol, affects a person’s vocal cords, voice box (larynx), or other areas of the throat.Throat cancer can also affect the piece of cartilage (epiglottis) that acts as a lid for your windpipe.

Managing Throat Cancer

•    Find it, as early as possible

•    Confirm Diagnosis (radiology and pathology)

•    Surgery (cut it out)

•    Radiation (burn it)

•    Chemotherapy (selective poisoning)

•    Combine the above

Pre-procedure requirement

·         Different methods are used to obtain tissue for a biopsy, depending on the location of the tumor. Some of the techniques are conventional incisional biopsy, fine-needle-aspiration biopsy (FNA) and Endoscopy.

•            Imaging tests have to be done, which may include: CT or CAT scans, PET scans, MRI scans, Chest and dental X-rays.
•           Set of X-rays of the esophagus and stomach may be used to look for cancer and find out how well you swallow.
•           Laryngeal videostroboscopy is necessary that lets the doctor look at the larynx and see how well you swallow.

Strategy in Diagnosing Throat Cancer

•    Determine exact location of throat cancer lesion

•    Find out the extent of spread of throat cancer - local, regional and systemic

•    Confirm throat cancer with the diagnosis with  histo-pathological  investigation like biopsy

•    Ascertain the patient’s fitness to undergo treatment

Use a multi-modality approach if necessary to treat the disease, using:

1.           Surgical removal of the diseased part of body

2.          Loco-regional control of disease with radiation

3.          Systemic control of disease with Chemotherapy

•    Giving Patient the best quality of life possible with rehabilitation measures

•    Regular monitoring for any recurrence of disease

Tests for Throat Cancer

•    Patient’s general fitness

•    Radiological investigations for determining the extent of disease and staging

•    Biopsy is required for diagnosis

•    Performed in operation theater with patient under anesthesia

•    Other potentially required tests:

1.           Direct laryngoscopy

2.          Bronchoscopy

3.          Esophagoscopy

4.          Chest X-ray

5.          CT or MRI

6.          Liver function tests with or without US

Staging for Throat Cancer

Stae 1 and 2

Mild, usually curable.  Radiation therapy followed by surgery if necessary

Stage 3

Chances the cancer has spread are high. Radiotherapy alongside chemotherapy.  Surgery usually precedes radiotherapy, but not always.

Stage 4

Can be treated but not likely curable.  Same treatment as Stage 3. mostly palliative.

Surgery and Side Effects in Throat Cancer

Throat Cancer Treatment in India

Throat cancer refers to cancerous tumors that develop in your throat (pharynx), voice box (larynx) or tonsils. Most throat cancers are squamous cell carcinomas. This means they develop in the squamous cells that line the throat. The main risk factors for throat cancer are smoking or using smokeless tobacco and use of alcohol. Symptoms of throat cancer are trouble breathing or speaking, frequent headaches, pain or ringing in the ears, trouble swallowing and ear pain. You can reduce your risk of throat cancer by not smoking, not chewing tobacco and limiting alcohol use.

The treatment will depend on the type of cancer and how far it has spread. Minimally invasive endoscopic surgery is a new technique that removes the whole tumor through the mouth, without incisions and little or no change in speech and swallowing. 

Other procedures that can be employed are Transoral Laser Microsurgery (TLM), Transoral Robotic Surgery (TORS) and Supracricoid Partial Laryngectomy. 

Surgery for early stage throat cancer is bound to the throat surface or the vocal cords. There are surgeries to remove all or part of the voice box called Laryngectomy and Pharyngectomy to remove all or part of the throat. Surgery is the preferred treatment for early stage throat cancers. For advanced stage or recurrent throat cancer, we may combine surgery with other forms of treatment, such as radiation therapy and chemotherapy.

HIFU in India : HIFU Ultrasound Hope for Prostate Cancer Patients

HIFU Ultrasound Hope for Prostate Cancer Patients 

Soundwaves could help 95% of prostate cancer patients … without affecting sex life,”  Its story comes from a small study that looked at an experimental treatment using high-intensity focusedultrasound (HIFU) to target areas of prostate cancer in men where the disease had not spread.

Standard treatments for prostate cancer often lead to undesirable side effects, in particular erectile dysfunction and urinary incontinence. Researchers found that a year after this experimental treatment, 89% of men still had erectile function and all were still continent. Ninety-five per cent of the men showed no evidence of disease on an MRI scan.

The results of this small study look promising. Men with early (localised) prostate cancer that has not spread can often live for years without developing life-threatening symptoms, and are often faced with a difficult decision about whether or not to have conventional treatment, which can have side effects. A treatment that can target areas of cancer without damaging healthy tissue might enable more men to have treatment for prostate cancer at an early stage.

However, it’s important to point out that this is an early “proof of concept” study and that a far larger trial is required to assess both its effectiveness and safety.This was an early (prospective development) study looking at a new treatment for localised prostate cancer called high-intensity focused ultrasound (HIFU).

Prostate cancer is the most common cancer in men, yet, as the authors point out, treating localised prostate cancer is difficult since the disease often progresses slowly and may not cause any symptoms for many years. There are several standard treatments for localised prostate cancer. Some involve treating the whole prostate with radiotherapy or removing it with surgery, and these can damage surrounding healthy tissue. The more destructive treatments of the whole prostate gland lead to undesirable side effects, in particular, erection problems (affecting 30-70% of men treated) and urinary incontinence (affecting 5-20%). One alternative for men at present is to have no active treatment but to undergo regular checks. This is known as active surveillance.

The new treatment, say the authors, is less aggressive and able to target the cancer site rather than the whole organ. In this respect, it is similar to treatment for other malignancies, such as localised breast cancer (where a lumpectomy is now an alternative to mastectomy). They say that in a previous study they had used HIFU to destroy one half of the prostate where the cancer was situated. But they point out that only one in five men have disease in one half of the prostate only. Their new study looked at whether HIFU could be used for treating cancer at specific sites within the prostate.

Advantages of HIFU Treatment :-

 • No blood loss

 • Quick recovery

 • Non surgical

 • Radiation free

 • An outpatient procedure

This is most modern technique ideal for treatment of low grade prostate cancer. It involves no surgery, no radiation , good cancer control, minimal morbidity. HIFU helps to improve the quality of life after Treatment and there are some more advantages like early return of erections and good urinary control.

The most common cancer of a reproductive system of a woman is known as uterine cancer.

EndometrialCancer (Uterine Cancer)

Uterine (Endometrial) cancer originates in the female reproductive system and generally affects postmenopausal women between ages 50 and 60;. It develops in the body of the uterus or womb whose wall has an inner lining (called the endometrium) and an outer layer of muscle tissue (called the myometrium). 

Endometrial cancer (Uterine Cancer) is often detected at an early stage because it frequently produces vaginal bleeding between menstrual periods or after menopause. If discovered early, this slow-growing cancer is likely to be confined to the uterus. Removing the uterus surgically (Hysterectomy) successfully eliminates endometrial cancer, if detected and carried out in the initial stages. 

The most common cancer of a reproductive system of a woman is known as uterine cancer. This cancer starts in cell layers that form the lining of the uterus. This cancer can be detected in its early stage as it causes abnormal vaginal bleeding. The surgical removal of the uterus can cure uterine cancer.

Types of Uterine Cancer :- 

Sarcoma: Sarcoma cancer grows in the supporting tissues of the uterine glands or in the myometrium. This cancer accounts for 2-4% of uterine cancers.

Adenocarcinoma: This cancer is considered as the main type of uterine cancer that grows from the cells in the uterus lining. Endometrial cancer is the other name of this cancer.

The Symptoms of Uterine Cancer include :

• Unusual Vaginal Bleeding or Discharge
• Trouble Urinating
• Pelvic Pain
• Pain during sexual intercourse
• Discomfort or pain in the lower abdomen

Diagnosis of Endometrial Cancer (Uterine Cancer)

A pelvic exam is performed by the doctors checking the vagina, uterus, ovaries, bladder, and rectum for Endometrial Cancer (Uterine Cancer). An instrument called a speculum is used to widen the vagina so the doctor can see the upper portion of the vagina and the cervix.

The Pap Smear test is often performed during a pelvic exam Endometrial Cancer (Uterine Cancer). The doctor uses a wooden scraper (spatula) or small brush to collect a sample of cells from the cervix and upper vagina. The cells are then sent to a medical laboratory to be checked for abnormal changes. Because uterine cancer begins inside the uterus, it may not show up on a Pap test, which examines cells from the cervix.

A biopsy may be needed for a definitive diagnosis where the doctor removes a sample of tissue from the uterine lining. In some cases, a woman may require a dilation and curettage (D&C), which is usually a day care procedure. During a D&C, the opening of the cervix is widened and the doctor scrapes tissue from the lining of the uterus. A pathologist examines the tissue to check for cancer cells, hyperplasia, or other conditions.

Common Endometrial Cancer (Uterine Cancer) Symptoms

•   Abnormal bleeding- heavy bleeding between periods, or heavy bleeding  during irregular periods
•    Pain during intercourse, pelvic pain or pain in the legs or back
•    Difficulty urinating or pain during urination
•    Enlarged uterus , Vaginal discharge and or unexplained weight loss

Surgical Treatment of EndometrialCancer (Uterine Cancer)

Surgery is the best option when Endometrial Cancer (Uterine Cancer) is diagnosed in its very early stages. At this time, the location and the stage of cancer make removal easy. Sometimes patients are treated with a combination of surgery and radiation therapy. Laparoscopy Assisted Vaginal Hysterectomy - involves the minimally invasive or open surgery to remove the uterus. If required teh surgeon may decide to remove both ovaries and the fallopian tubes if there is a risk of Endometrial cancer spread to the ovaries.

In most cases, uterine cancer is an Adenocarcinoma that metastasizes late, usually from the endometrium to the cervix, ovaries, fallopian tubes, and other peritoneal structures. It may spread to distant organs, such as the lungs and the brain, through the blood or the lymphatic system. In such cases advanced tratement post Hystrectomy like Chemotherapy and Radiation are advised

Chemotherapy 

Involves modern cancer drugs that are administered intravenously or orally to kill cancer cells and to reduce the chances of the tumour returning elsewhere in the body.


Radiation therapy 

India's leading Cancer hospitals now have some of the world's moset advanced radiation equipment like Linac, Novelis, Gamma Knife and Cyberknife for treating Cancers. High technology radiation is used to kill cancer cells without affecting the healthy tissues. Radiation may be used to reduce the tumor prior to surgery or to obviate the symptoms of  cancer such as pain, bleeding, or blockage.

The CyberKnife Robotic Radiosurgery System can treats both cancerous and non-cancerous tumors anywhere in the body

How Cyberknife RadioSurgery Works ?

As a non-invasive “operation”, CyberKnife has proven to be an effective alternative to surgery or conventional radiation for treating vascular abnormalities, tumors, functional disorders, and cancers with sub-millimeter accuracy. CyberKnife gives renewed hope and the possibility of a better quality of life, especially for patients with tumors previously diagnosed as inoperable, and for those who have already received the maximum amount of radiation through other treatment methods.

The CyberKnife uses non-invasive image-guided localization that is more convenient and less traumatic than other systems using the standard invasive stereotactic headframe (a rigid metal frame fixed to a patient’s skull for head immobilization and target localization). CyberKnife also uses an advanced, lightweight linear accelerator (LINAC), a device used to produce a high dose of radiation.

In addition, CyberKnife also has a robotic delivery system that not only provides the flexibility to reach areas of the body unreachable by other systems, but is also instrumental in precisely aiming the device.

The robotic delivery system integrates motion-tracking software, called the Synchrony System, with the robotics, making it accurate enough to even hit a moving target. As a patient breathes or moves slightly during treatment, the robot detects the motion and compensates in ‘real time’, ensuring that the radiation is accurately hitting the target (tumor) throughout treatment.

CyberKnife can strike the tumor with a high dose of radiation from over 1200 different angles. This pinpoint accuracy allows malignant or benign tumors to be obliterated without damaging critical healthy tissue.
 

How is CyberKnife Different ?

Standard stereotactic radiosurgery techniques rely on a rigid frame fixed to the patient's skull for head immobilization. There are other systems for extra-cranial Stereotactic Radiation. These systems are most often uncomfortable. If the target moves with the breathing of the patient, they often require breath holding techniques, which may be difficult for some patients. Frame-based systems mean there is a limit to the number of angles the radiation can be delivered through.

The CyberKnife System offers maneuverability and versatility that other systems cannot offer, therefore now making it possible to treat tumours anywhere in the body, especially the brain, spine, liver, lung, pancreas and prostate. The combination of image guidance with the help of X-ray cameras and the very latest computer technology ensures that the CyberKnife® System is able to overcome the limitations of older frame-based radiosurgery systems, such as the Gamma Knife and LINAC based X-Knife.

treatment to the tumor alone, sparing surrounding healthy tissue.

What can the CyberKnife treat?

The CyberKnife Robotic Radiosurgery System is a non-invasive alternative to surgery for the treatment of both cancerous and non-cancerous tumors anywhere in the body, including the prostate, lung, brain, spine, liver, pancreas and kidney. The treatment - which delivers high doses of radiation to tumors with extreme accuracy - offers new hope to patients who have inoperable or surgically complex tumors, or who may be looking for a non-surgical option.

What is the treatment course?

CyberKnife treatment is performed on an outpatient basis. The patient receives an initial consultation with the radiation oncologist and surgeon. A CT scan (3-D X-ray) is obtained. The 3-D image obtained is used by the physicians, physicists and team to create a treatment plan.

The patient will return for the one-hour treatment within a few days after the consultation.

The number of treatments will vary depending on tumor size, location and shape, but the number of treatments is usually between one and four.

Whatare patient benefits?

• Better quality of life during and after treatment
• Head frames not used as with other stereotactic radiosurgery programs
• Performed on an outpatient basis
• Less pain
• No incisions
• Risk is minimized to healthy tissue surrounding tumor/lesions
• Fewer visits to the hospital
• Short recovery period
• Treatment is available for tumors considered inoperable by other surgery and stereotactic radiosurgery methods
• Lower risk of complications when compared to other treatment options
• Lower risk of infections
• Lower risk of hemorrhage/severe blood loss
• Lower risk of hearing loss
• Lower risk to alteration in feeling of extremities

How colon cancers are diagnosed | Low Cost Colon Cancer Treatment in India

Diagnostic tests for colorectalcancer are usually done when:

• the symptoms of colorectal cancer are present
• the doctor suspects colorectal cancer after talking with a person about their health and completing a physical examination
• screening tests suggest a problem with the colon or rectum

Many of the same tests used to initially diagnose cancer are also used to determine the stage (how far the cancer has progressed). Your doctor may also order other tests to check your general health and to help plan your treatment. Tests may include the following.

Medical history and physical examination The medical history is a record of present symptoms, risk factors and all the medical events and problems a person has had in the past. The medical history of a person's family may also help the doctor to diagnose colorectal cancer. In taking a medical history, the doctor will ask questions about: a personal history of polyps in the colon or rectum inflammatory bowel disease colorectal cancer a family history of colorectal cancer familial adenomatous polyposis hereditary non-polyposis colorectal carcinoma (also known as Lynch syndrome) signs and symptoms Tumour marker tests Tumour markers are substances – usually proteins – in the blood that may indicate the presence of colorectal cancer. Tumour marker tests are used to check a person's response to cancer treatment, but they can also be used to diagnose colorectal cance Colonoscopy A colonoscopy is a procedure that lets the doctor look at the lining of the colon using a flexible tube with a light and lens on the end (an endoscope). A colonoscopy is preferred over a flexible sigmoidoscopy because the entire colon can be checked for polyps or abnormal areas. A colonoscopy is done in a hospital on an outpatient basis. The doctor gently inserts the colonoscope (a type of endoscope) through the anus and slowly moves it into the rectum and colon. The colon is inflated with air to stretch out the lining so the doctor can look at the entire surface. This can be uncomfortable, so drugs are given to help the person relax during the procedure. Biopsy During a biopsy, tissues or cells are removed from the body so they can be tested in a laboratory. The pathology report from the laboratory will confirm whether or not cancer cells are present in the sample and may also identify the type of cancer. A biopsy is the only definite way to diagnose colorectal cancer. Biopsies of polyps or abnormal areas are taken during a sigmoidoscopy or colonoscopy. A biopsy sample will allow the doctor to find out the type of colorectal cancer and the grade. Biopsy results may also show how far the cancer has grown through the wall of the colon or rectum. Computed tomography (CT) scan A CT scan uses special x-ray equipment to make 3-dimensional and cross-sectional images of organs, tissues, bones and blood vessels inside the body. A computer turns the images into detailed pictures. It is used to: check if the cancer has spread to other organs in the abdomen or pelvis (small areas of spread [microscopic spread] may not be detected by CT scan) check if the cancer has spread to the lymph nodes in the abdomen check how far the tumour has grown into the wall of the colon or, especially, the rectum CT-guided needle biopsy CT scans may also be used to help guide a needle to perform a biopsy (CT-guided needle biopsy) to check for cancer cells in a tumour in the colon or a suspected area of metastasis (cancer spread outside of the colon or rectum). Virtual colonoscopy Virtual colonoscopy uses a CT scan to create images of the colon without having to insert an endoscope through the rectum. A virtual colonoscopy is less invasive and more comfortable than a regular colonoscopy. Studies are continuing to examine the effectiveness of this test.  Ultrasound  Ultrasound uses high-frequency sound waves to make images of structures in the body. Endorectal ultrasound (EUS or ERUS) uses a special instrument (transducer) that is inserted into the rectum. It is used to see: how far a tumour has grown into the rectal wall if the tumour has spread to nearby organs or lymph nodes Abdominal ultrasound may be done to see if the cancer has spread to other organs in the abdomen, such as the liver. Pelvic ultrasound may be done if doctors suspect that the cancer has spread to the urinary tract. An ultrasound may also be used during abdominal surgery. The surgeon can place the transducer directly on the liver to check for metastases. Positron emission tomography (PET) scan A PET scan uses radioactive materials (radiopharmaceuticals) to detect changes in the metabolic activity of body tissues. A computer analyzes the radioactive patterns and makes 3-dimensional colour images of the area being scanned. PET scans are not routinely used to diagnose colorectal cancer. They are more commonly used to help stage and check for recurrent disease if a person's CEA level starts to rise following treatment. PET scans are not readily available at all centres.
