Tumor resection
Patients unable to receive complete resection or at high risk of rupture
underwent biopsy prior to treatment. Tumor resection was considered when
primary tumor shrank approximate
to 2cm × 3cm to minimize risk of rupture or spillage during resection.
Tumor resection field included the tumor pseudocapsule and en-bloc
coccyx bone as possible. Tumors were resected in toto without proof of
rupture as possible as surgeons
could[2].
