The purpose of this study is to compare the efficacy and safety of different doses of sirolimus in the maintenance treatment of kaposiform hemangioendothelioma.
Kaposiform hemangioendothelioma (KHE) is a rare aggressive vascular neoplasm that occurs predominantly in infancy or early childhood, with an incidence of approximately 0.071/100,000. Currently, sirolimus is a promising treatment modality for KHE. Most scholars consider sirolimus blood concentration of 5-15 ng/ml to be an effective therapeutic concentration, while 10-15 ng/ml is the most commonly used blood concentration. However, long-term higher dose sirolimus treatment can cause some common adverse effects, such as oral mucositis which affects the quality of life of the patient. Finer control of the plasma concentration of sirolimus may contribute to the efficacy of treatment and reduce the incidence of complications. Previous studies have found good efficacy of low-dose sirolimus maintenance treatment for KHE. However, there is no high-level evidence to support this treatment strategy. Therefore, we conducted this study to find out whether an early reduction in sirolimus dose would benefit the prognosis of the patients.

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

The changes in KHE volume
Response to therapy was measured by volumetric magnetic resonance imaging (MRI) analyses were performed at baseline and 6 and 12 months after treatment and were independently assessed by 2 radiologists. Changes in KHE size were classified as further growth (increase of ≥10%), no change (\<10% increase and \<10% decrease), partial involution (decrease of ≥10% and \<75%), nearly complete involution (decrease of ≥75% and \<100%), or complete involution (100%).
Time frame: 12 months.
Quality of life (QOL) in patients
Pediatric Quality of Life Inventory (PedsQLTM) 4.0 Genetic Core Infant Scales (\<2 years) or Pediatric Quality of Life Inventory (PedsQLTM) 4.0 Genetic Core Scales (2-18 years) were used.
Time frame: Baseline, 6 months, 12 months.
Frequency of adverse events
Frequency of adverse events (e.g. gastrointestinal disorders, blood and lymphatic system disorders, metabolic disorders or other abnormal laboratory results, skin disorders and general disorders, etc.) collected by investigator and reported by parents. All adverse events were collected and graded according to Common Terminology Criteria for Adverse Events, version 4.0 (CTCAE v4.0). The causality of the adverse event was determined by the multidisciplinary staff and was classified as definitively not related, probably not related, possibly related, probably related, or definitively related. Any dose reductions, interruptions, or cessations enacted at the discretion of the investigators were recorded.
Time frame: Baseline, 6 months, 12 months.
The changes in the patient's musculoskeletal complication.
The severity of musculoskeletal complication was scored by using a 4-point scale: 1, asymptomatic or mild symptoms, clinical or diagnostic observations only; 2, moderate symptoms, limiting age-appropriate instrumental activities of daily living; 3, severe or medically significant symptoms, disabling or limiting self-care activities of daily living; and 4, life-threatening consequences, with urgent intervention indicated.
