TARGIT - IORT

NICE recommends TARGIT IORT for breat cancer

Intrabeam TARGIT IORT is targeted intraoperative radiotherapy treatment for breast cancer. Conceived in the UK more than 20 years ago, thoroughly tested in clinical trials, TARGIT IORT treatment is widely used to treat breast cancer patients across the world.

“The most important benefit of TARGIT for a woman with breast cancer is that it allows her to complete her entire local treatment [lumpectomy and radiation therapy] at the time of her operation, with lower toxicity.”  Lancet 2014;383:603-613

Special relevance of TARGIT-IORT during the COVID-19 pandemic

 

TARGIT-IORT is given as a single dose during the cancer operation - so in most patients no visits to the radiotherapy department are required. This is especially relevant during the COVID-19 pandemic. When the radiotherapy is completed during the cancer operation, under the same anaesthetic, it greatly reduces the need for repeated post-operative visits to the hospital for postoperative external beam radiotherapy which are necessary for regimens such as IMPORT-Low or Fast-Forward which irradiates the whole breast.

This is why it has been included in several national and international guidelines for treatment of breast cancer during the COVID-19 pandemic caused by the widespread infection with the SARS-CoV-2 virus

During the COVID-19 pandemic, new guidelines for treatment of beast cancer  and radiotherapy have recommend using TARGIT-IORT because it would save patients the daily travel (and viral exposure) to radiotherapy departments:

Information about Intrabeam TARGIT IORT

Why is radiotherapy used for breast cancer?


Breast cancer is frequently treated by surgically removing the cancerous lump with a margin of surrounding normal tissue. Radiotherapy to the remaining breast after such a lumpectomy reduces the risk of cancer coming back in the breast. Traditional external beam radiotherapy (EBRT) is given to the whole breast a few weeks after surgical removal of the cancer. As it is not focused, it needs to be given in daily small doses over three to six weeks.




What is Intraoperative radiotherapy | Intrabeam | TARGIT | IORT for breast cancer?


TARGIT IORT stands for TARGeted Intraoperative radioTherapy. It is given during a lumpectomy for breast cancer, under the same anaesthetic, and it can replace traditional radiotherapy in suitable patients. The TARGIT technique and the Intrabeam device was developed by clinical academics at University College London in 1998 in collaboration with the manufacturers. After a cancer has been removed from the breast, TARGIT IORT allows your doctor to deliver a dose of radiotherapy directly into your breast, focussed to the site where the tumour had been. A small ball-shaped radiation applicator of the Intrabeam device is precisely placed in the tumour bed – the cavity left behind when the tumour is removed. TARGIT IORT is given over about 25 minutes, the applicator then is removed and skin closed. Intrabeam TARGIT intraoperative radiotherapy effectively treats the tissues where cancer might have come back while avoiding radiation to the skin and other healthy tissues such as the heart and lungs This method has been used worldwide (over 300 centres in 38 countries) to treat over 40,000 patients.




What is the surgical procedure of giving TARGIT IORT?


TARGIT IORT is given using the Intrabeam device. It is given during your surgery, while you remain asleep, under general anaesthetic. It adds about 30 minutes to the operation. It allows your specialist to deliver a focused dose of radiotherapy into the space where the breast cancer had been. This means that the radiotherapy is accurately targeted within the breast. This method avoids the potential damage to the skin, heart and lungs from traditional radiotherapy. You do not feel any effects from the radiotherapy and there are no additional scars on your breast. The surgical technique of Intrabeam TARGIT IORT, simplified: The surgeon removes the cancerous lump from the breast. The cancer and some surrounding normal tissue - the margin - is removed, leaving a small space called the tumour bed. A ball-shaped radiation small applicator is positioned precisely within the breast cavity, at the site of tumour, using meticulously placed sutures. Intrabeam TARGIT IORT is given as focused dose of targeted intraoperative radiotherapy into the breast, avoiding damage to the skin, heart and lungs.This takes about 30 minutes The breast wound and skin is surgically closed as usual.




Has TARGIT IORT been clinically tested for breast cancer?


TARGIT IORT has been extensively tested in clinical trials over the past 20 years. The TARGIT-A trial, included 3451 patients treated in 33 hospitals in UK, Europe, USA and Australia and this trial compared TARGIT IORT with traditional radiotherapy. TARGIT IORT is given using the Intrabeam device. TARGIT IORT avoids radiation to the whole breast. It is given from within the breast, so the skin is protected. Therefore, it has only minimal side effects. Clinical trial results show that radiation treatment side effects are fewer compared with traditional radiotherapy and the cosmetic outcome is similar to or better. The five-year results showed that when TARGIT is given at the same time as lumpectomy, the local-recurrence-free-survival is similar to traditional radiotherapy: 93.9% with TARGIT vs. 92.5% with traditional EBRT. As with all breast cancer treatments there is some uncertainty about the exact difference in local recurrence after TARGIT IORT compared with traditional radiotherapy. However, the UK National Institute of Care and Excellence have determined that such difference is very small (1 to 2%) and have recommended it for suitable patients in the NHS.




What will it involve?


You will have your surgery the usual way and TARGIT IORT will be given using the Intrabeam device during the operation, under the same anaesthetic. Afterwards you will be able to go home on the same day or after an overnight stay. The wound care is similar to a standard operation, but the sutures or ‘Steristrips’ need to be left for 14 days. Compared with traditional treatment, there is a lower risk of skin injury, but a slightly (1%) higher chance of fluid collecting in the wound. This does not delay the healing process. Sometimes, in 15-20% of women, additional information from analysis of the cancer after surgery may mean that a smaller course of traditional EBRT required after TARGIT.




Who can and cannot have TARGIT IORT?


Women who are 45 or older with invasive ductal type cancer suitable for breast conservation (tumour size up to 3.5cm) are eligible to receive TARGIT IORT instead of EBRT. Other women who have a higher risk cancer can receive TARGIT as a tumour-bed boost in addition to EBRT within the TARGIT-B trial. Women who need a mastectomy are not suitable.




Key Benefits of Intrabeam TARGIT IORT


Takes less time: TARGIT IORT is given during your surgery rather than after a few weeks' delay before a three or four week course of daily doses of traditional radiotherapy. Precise radiotherapy: The radiotherapy is given into the breast exactly where the cancer had been, ensuring that it is accurately delivered. Protects health tissues: There is reduced toxicity or damage to the skin, heart or lungs. Avoids delay: Radiotherapy does not need to be delayed until after chemotherapy. Flexible for your needs: Intrabeam TARGIT IORT can be supplemented with whole breast radiotherapy if it is thought necessary later on Quality of life and cosmetic results: are as good or better than traditional radiotherapy




Key Concerns about Intrabeam TARGIT IORT


Possible need for further radiotherapy: About 15-20% of patients may need to receive traditional radiotherapy in addition to TARGIT IORT if it is felt necessary after detailed microscopic examination of the tumour after surgery. The safety of TARGIT IORT is well established with 5-year median follow available for 1222 patients. With longer follow up, local recurrence with TARGIT may be 1% - 2% higher than traditional radiotherapy. This does not reduce survival; in fact, there are fewer deaths with targeted radiation compared with whole breast radiation.

NICE Recommendation


In February 2017 NICE issued a press release stating that they have recommended the use of TARGIT IORT in the treatment women with early breast cancer. https://twitter.com/NICEcomms/status/831850566741471233 NICE issued their final guidance on 31 January 2018 https://www.nice.org.uk/guidance/ta501 Click here for a printable information to help in a shared decision making that has been prepared by TARGIT IORT specialists in collaboration with patients.

What is gambling?


Actually there is no single, clear cut definition of what gambling is but it is widely agreed that: Two or more people agree to take part in the activity (usually an operator and the person who wishes to gamble); Normally money (the ‘stake’) is paid by the loser to the winner; The outcome is uncertain and the activity involves risk; The result is determined at least partly by chance; Participation is an active experience but can be avoided by not taking part.




What is problem gambling?


Problem gambling is an urge to continuously gamble despite harmful negative consequences or a desire to stop. Problem gambling is often explained by whether harm is experienced by the gambler or others, rather than by the gambler’s behaviour. Severe problem gambling may be diagnosed as clinical pathological gambling if the gambler meets certain criteria. Pathological gambling is a common disorder that is associated with both social and family costs.

What is Responsible Gaming?


Today, you can bet anywhere, anytime on just about anything. With opportunities to gamble increasing and advertising enticing us to gamble more frequently, spreading the word about how to gamble safely is becoming more important than ever. For us, responsible gambling is about both the individual gambler and the wider community. Responsible gambling for individuals means:

  • They may gamble for pleasure and entertainment but are aware of their likelihood of losing and understand the associated risks,
  • They exercise control over their gambling activity, and
  • Responsible gambling occurs in balance with other activities in their lives and is not causing problems or harm for themselves or others.
Responsible gambling for the broader community, including gambling providers, governments, and sporting associations, requires:
  • Shared responsibility for generating awareness of the risks associated with gambling,
  • Creating and promoting environments that prevent or minimise problem gambling, and being responsive to community concerns around gambling.
