About this trial
The goal of this observational study is to evaluate the long-term effects of sacral tumor resection on sacral nerve function in patients with primary sacral tumors, including chordomas and chondrosarcomas. The study will primarily focus on understanding how the level of sacral resection impacts postoperative motor, bowel, bladder, and sexual functions. The main questions it aims to answer are:
How does the level of sacral resection influence bowel and bladder function at 12 months post-surgery? What is the role of preserving the sacral nerve root in maintaining motor function and sexual function? Participants will include patients who have undergone sacral tumor resection and will be followed for 12 months post-surgery. They will provide data on their bowel, bladder, and motor functions, as well as sexual function, through clinical evaluations and standardized questionnaires.
Participants will:
Complete surveys on bowel, bladder, and motor function at baseline and at 3, 6, and 12 months after surgery Undergo clinical assessments, including anorectal manometry, post-void residual urine volume measurements, and sensory evaluations Be evaluated for changes in sexual function using standardized surveys like IIEF (for males) and FSFI (for females)

Trial population
The study population includes patients aged 12 to 80 years diagnosed with sacral tumors (either primary bone tumors or metastases from other solid tumors) who are scheduled for surgical resection at Shanghai Changzheng Hospital. All participants must meet inclusion criteria and provide informed consent. The study will assess postoperative motor, bowel, and bladder function, pain, quality of life, and complications. Patients unable to tolerate surgery or with pre-existing bowel/bladder dysfunction will be excluded. A total of 400 patients will be enrolled.

Trial outcomes
Primary outcomes
Bladder Function Score at 12 Months Post-Surgery
The primary outcome measure will assess bladder function 12 months after sacral tumor resection surgery. Based on the Biagini et al. method and supported by literature such as Huang et al the bladder function scoring system commonly used in sacrectomy outcome studies includes the following components: 0-Normal 1. Feels stimulus to micturate and has limited continence at varying times and quantities of urine and/or has increasing postmicturition vesical residual and/or urinary loss in conditions of stress 2. Does not feel stimulus to micturate and/or is completely incontinent
Secondary outcomes
Rectal Function Score at 12 Months Post-Surgery
The secondary outcome measure will assess rectal function 12 months after sacral tumor resection surgery. Based on the Biagini et al. method and supported by literature such as Huang et al the Rectal function scoring system commonly used in sacrectomy outcome studies includes the following components: 0-Normal 1. Feels stimulus to defecate and is incontinent when feces are soft or under stress 2. Does not feel stimulus to defecate and/or is completely incontinent
Other outcomes
Pre-Surgical Baseline Information-Age
Patient age at the time of surgery, recorded in years as a continuous variable.
Pre-Surgical Baseline Information-Gender
Patient sex as recorded in the medical record (male or female).
Pre-Surgical Baseline Information-Time from Treatment Initiation to First Diagnosis
The duration, in months, between the initiation of any relevant prior treatment (e.g., symptomatic management, imaging, or biopsy) and the date of histopathological diagnosis of sacral tumor
Pre-Surgical Baseline Information-Body Mass Index (BMI)
Calculated as weight in kilograms divided by height in meters squared (kg/m²), recorded as a continuous variable.
