Study summary

This study will evaluate whether a short nutritional intervention before surgery can improve recovery in patients with bone and soft tissue sarcomas.

Patients with these tumors often have a higher risk of poor nutrition and loss of muscle mass. These problems may increase the risk of complications after major orthopedic surgery.

Participants will be randomly assigned to one of two groups. One group will receive a special oral nutritional supplement twice daily before surgery, in addition to standard care. The other group will receive standard care without the preoperative nutritional supplement.

The main aim of the study is to compare the rate of clinically relevant postoperative complications within 30 days after surgery. The study will also evaluate changes in muscle mass on CT scans, blood markers of nutrition and inflammation, nutritional risk, functional status, length of hospital stay, and tolerance of the nutritional supplement.

Read the detailed description

Patients with bone and soft tissue sarcomas often require planned major orthopedic surgery as part of their treatment. These operations may include wide tumor resection and, in some cases, complex reconstruction of the affected limb or anatomical region. Because of the extent of surgery and the underlying oncologic disease, these patients may be at increased risk of postoperative complications, impaired wound healing, longer hospitalization, and slower functional recovery.

Nutritional status is an important factor that may influence surgical outcomes. Patients with sarcoma may develop malnutrition or reduced skeletal muscle mass due to the tumor itself, cancer-related systemic inflammation, decreased physical activity, reduced food intake, or previous oncologic treatment. Sarcopenia and poor nutritional reserve may decrease the patient's ability to tolerate major surgery and may contribute to a higher risk of postoperative morbidity.

Preoperative nutritional optimization is recommended in several areas of oncologic surgery, but evidence specifically focused on patients with bone and soft tissue sarcomas remains limited. In this population, there is no clear consensus regarding the optimal nutritional strategy, timing, or expected clinical benefit of short-term preoperative nutritional support. This creates a need for prospective data in real-world sarcoma care.

This prospective, randomized, controlled study will evaluate whether a standardized preoperative immunomodulatory nutritional intervention can improve postoperative outcomes in adult patients with histologically confirmed bone or soft tissue sarcoma who are scheduled for elective orthopedic tumor resection.

Eligible participants will be randomized to one of two study groups. Patients in the intervention group will receive standard care together with preoperative oral immunomodulatory nutritional support before the planned surgery. Patients in the control group will receive standard care without additional preoperative nutritional supplementation. The intervention will be carried out in the home setting during the preoperative period, reflecting routine clinical practice.

Patients will undergo nutritional assessment by a clinical nutrition therapist during the diagnostic and preoperative treatment pathway. If sarcoma is confirmed and the patient is indicated for planned orthopedic resection, the nutritional intervention will be prescribed for home use in the intervention group. At admission for surgery, adherence to the supplement and tolerance of the nutritional intervention will be assessed.

The primary objective of the study is to determine whether preoperative immunomodulatory nutrition reduces the occurrence of clinically relevant postoperative complications within 30 days after orthopedic resection. Complications will be evaluated using a standardized classification system and assessed through blinded review of medical records.

Secondary objectives will assess several aspects of perioperative recovery and nutritional status. These include changes in skeletal muscle mass using CT-based body composition analysis, laboratory markers related to nutrition and systemic inflammation, baseline nutritional risk, preoperative functional status, length of hospital stay, and the feasibility of the intervention based on adherence and tolerance.

The study will use CT scans performed as part of standard oncologic staging and restaging to evaluate changes in muscle mass. This approach allows assessment of sarcopenia without adding imaging procedures beyond routine clinical care. Laboratory parameters and clinical assessments will also be collected within the standard perioperative pathway whenever possible.

The study is designed to reflect real-world treatment conditions in a tertiary sarcoma center. The results may help clarify whether short-term preoperative immunonutrition is feasible and clinically useful in patients with bone and soft tissue sarcomas undergoing major orthopedic surgery. The findings may also support future development of perioperative nutritional protocols for this high-risk patient population.

Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Informed consent

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.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Study arms

  • Experimental
    Intervention Group

    Participants in this arm will receive standard perioperative care plus preoperative oral immunomodulatory nutritional support. The nutritional supplement will be taken at home before the planned orthopedic tumor resection. Adherence to the supplement and tolerance of the intervention will be assessed at hospital admission for surgery.

    Dietary Supplement: Forticare Advanced oral nutritional supplement

  • No intervention
    Control Group

    Participants in this arm will receive standard perioperative care without additional preoperative oral immunomodulatory nutritional supplementation. This arm reflects routine clinical practice and will serve as the control group for comparison with the intervention arm.

Interventions

  • Dietary supplementForticare Advanced oral nutritional supplement

    Participants randomized to the intervention arm will receive preoperative oral immunomodulatory nutritional supplementation in addition to standard perioperative care. The supplement will be taken at home before the planned orthopedic tumor resection. The prescribed regimen will be Forticare Advanced oral nutritional supplement, 125 mL twice daily, for 14 days before surgery when clinically feasible. If the full 14-day period is not possible due to the clinical schedule, supplementation for at least 7 days will be accepted.

Of 34 non-industry interventional studies with no phase under Bone Neoplasms, half reached primary completion within 51 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 70. This study's planned 20 months is below that.

Counting every sponsor, half of 40 studies reached it within 50 months; a quarter within 14 and three quarters within 65.

Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 27, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
