Pediatric Tumor Resection

Neuroblastoma grows from nerve tissue, mainly in the adrenal gland. The international INRG staging system grades localized tumors by image-defined risk factors, features on the scans that make surgery at diagnosis dangerous, such as tumor wrapped around major vessels. In 661 European children, those without these features had 90 percent event-free survival at five years, against 78 percent for those with them, and surgeons give chemotherapy first when they are present.

For high-risk neuroblastoma, the American A3973 analysis of 220 children found that removing at least 90 percent of the primary tumor was linked to better event-free survival, 45.9 against 37.9 percent at five years, and fewer local recurrences, 8.5 against 19.8 percent. Overall survival did not change. Surgeons aim for the most complete removal that is safe, without sacrificing the kidney or major vessels.

Wilms tumor leads the kidney cancers of childhood. European SIOP protocols give four weeks of chemotherapy before removing the kidney, which shrinks the tumor and lowers the risk of it rupturing during surgery, while North American protocols remove the kidney first in most children. Both approaches cure most children.

SIOP WT 2001 randomized 583 children with stage II to III intermediate-risk tumors, after surgery, to chemotherapy with or without doxorubicin, a drug that can damage the heart. Event-free survival at two years reached 92.6 against 88.2 percent, within the agreed margin, and five-year survival was 96.5 against 95.8 percent. Heart effects occurred in 5 percent of children given doxorubicin. Doctors dropped the drug for this group.

Bleeding, injury to nearby organs or vessels, and infection are the main early risks. Later, adhesions sometimes block the bowel. Across 1,910 children in the American NWTS-3 study, bowel obstruction after Wilms tumor surgery occurred in 6.9 percent, more frequently after larger tumors, involvement of the large veins or removal of other organs at the same time. Radiotherapy did not add to the risk.

Relapse still leaves room for cure. Children in the NWTS-5 study whose Wilms tumor recurred after treatment with two drugs and no radiotherapy were treated again with surgery where feasible, radiotherapy and stronger chemotherapy, and 81.8 percent were alive four years later.

Children recover faster than adults. Most walk on the first or second day, eat within a few days and return to play within weeks, and the change from a pale, tired child on the ward to one running down the hotel corridor a week later surprises many parents. Chemotherapy restarts two to three weeks after surgery.

Plan two to three weeks in Istanbul for the operation. The team coordinates chemotherapy and radiotherapy with your home oncologists, so that much of the treatment can continue closer to home. Children can fly once the wound has healed, they eat and walk well and their blood counts are safe, a week after leaving hospital for most children. Cost depends on the tests, the operation, intensive care and the hospital stay. Your own figure follows the free review of your file.

One coordinator arranges the visa invitation letter ten days ahead, the transfer and an apartment near the hospital for the family. A parent stays with the child throughout, play specialists and teachers help long stays pass, and the team works in seven languages with halal meals and a prayer room available. Back home, the surgical and oncology teams review scans and reports sent by your local doctors and stay reachable on the same WhatsApp number. Before you leave, the surgeon writes a full operation note and the pathologist a detailed report of the tumor and its margins, which your local oncologist needs to choose the right chemotherapy and decide on radiotherapy, and the team agrees the dates of the next scans with you so that follow-up continues without gaps, whether the child is treated at home or returns to Istanbul for reviews.
