Surgery and radiation: when and to whom?

May 11, 2021

These questions are answered by a renowned scientist, Israeli clinical oncologist, chairman of the Israel Cancer Association, member of the executive board of AROME, head of the council of consultants at the Israeli Oncology Hospital LISOD Professor Abraham Kuten:

The need for postsurgical radiation therapy depends on many factors: the location of the tumor, the histological type of the neoplasm, the stage of the disease, the type of surgery (which margins were obtained after the surgery, are they wide, are there signs of microscopic foci in these margins), etc. ... Taking into account all indicators and based on the specifics of a particular type of cancer, a consultation of specialists determines whether a patient in a particular clinical case needs radiation therapy in order to prevent a possible relapse.

By the way, note that for some tumors, radiation therapy is given after surgery, but there are also certain tumors that require preoperative radiation. Preoperative radiation allows you to stop cell division, to reduce the size of the tumor, in order to carry out the surgery in a smaller volume. The main goal of postoperative radiation therapy is to prevent relapse and to increase relapse-free survival.

Postoperative radiation (also called adjuvant radiation therapy) is usually given a few weeks after the tumor has been surgically removed - usually 3-6, sometimes 7 weeks. This time is necessary for the area where the intervention was performed to recover, so that radiation therapy does not interfere with tissue healing. But at the same time, it is necessary to start radiation therapy as soon as possible so that the microscopic cells remaining after the operation do not begin to divide and do not cause further relapse.

If radiation therapy is delayed for more than 7 weeks, the treatment may not be effective.

If you have any questions, you can consult with LISOD oncologists. We employ professionals with vast experience who know how to act in any situation. A consultation is an opportunity to get answers, as well as hear the recommendations of an international multidisciplinary council of specialists, which will determine the optimal tactics for further actions.
