The most vexing problem with hard fibroids is that they are very prone to recurrence after surgery. It is generally believed that if there is no recurrence of hard fibroids for 5 years after surgery, the patient is basically cured. However, according to the literature, the recurrence rate of hard fibroids is as high as about 50% within 5 years, and recurrence is most likely to occur within 2 years after surgery. The only effective way to prevent recurrence of hard fibroids is currently to perform postoperative radiotherapy. However, this approach can only slow down the “pace” of tumor recurrence, but not reduce the recurrence rate. The idea that pregnancy can induce the recurrence of sclerofibrosarcoma is still controversial. Therefore, for unmarried women, if they want to have a child after marriage, it is generally possible; however, for second children, it is recommended to avoid having a child, as there is a risk that pregnancy may cause the recurrence of hard fibroids. And what should be done when a recurrence of hard fibroids has already occurred? At this point, the same idea as the initial treatment is used, i.e. surgery if you can, and radiotherapy or chemotherapy if you cannot. It is important to note that when a recurrence occurs after the initial surgery, a second surgery is less likely to result in a clean resection. This is because the second surgery requires a larger excision, and this re-extended excision may lead to various complications. In addition, the recurrence rate after reoperation for hard fibroids is much higher than the recurrence rate after the initial surgery, and the recurrence time becomes shorter and shorter. There are even some patients with repeated recurrences and resections up to a dozen times. So, in order to avoid repeated surgeries, are other treatment methods such as Helio knife and Ar-He knife available? Because there is no trial data to support them, the effectiveness of these methods for treating hard fibroids is uncertain. Therefore, patients are not advised to try them easily. After the recurrence of hard fibroids, the tumor originally in the hip grows to the thigh, at this time, many people think it is a recurrence of metastasis of the tumor. In fact, hard fibroid is a benign tumor and does not metastasize. If the tumor originally grows in the hip and then appears in the thigh after surgery, and later grows to the N fossa and finally to the calf, this phenomenon is the tumor spreading along the vascular nerve bundle, which is not the same thing as metastasis.
