Repeat or Single Quadratus Lumborum Block for the Reduction of Opioid Prescriptions After Surgery in Retroperitoneal Sarcoma Patients ("RESQU-SARC" Trial)

Phase 2
Active, not recruiting
Conditions
Retroperitoneal Sarcoma
Interventions
Drug: Liposomal Bupivacaine
Drug: Quadratus Lumborum Block
Other: Questionnaire Administration
Registration Number
NCT04189783
Lead Sponsor
M.D. Anderson Cancer Center
Brief Summary

This phase II trial studies how well a repeat or single liposomal bupivacaine injection (quadratus lumborum block) works in reducing opioid prescriptions after surgery in patients with retroperitoneal sarcoma. Liposomal bupivacaine is a numbing medication. Giving a second injection block may decrease dependency on opioid medications for pain relief after surgery and prevent long-term use and addiction.

Detailed Description

PRIMARY OBJECTIVE:

I. To use a pragmatic phase II randomized controlled trial to compare two standardized bundles of usual care for postoperative pain management to reduce the initial discharge prescription opioid volume.

SECONDARY OBJECTIVE:

I. To assess which pragmatic arm improves aspects of postoperative recovery including 30-day, 3-month, and 1-year opioid use, patient symptom inventory at those time points, hospital measures including length of stay and inpatient pain scores.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive standard of care liposomal bupivacaine injection before and during surgery and standard of care non-opioids and opioids at days 0-3 after surgery in the absence of unacceptable toxicity.

ARM II: Patients receive standard of care liposomal bupivacaine injection before and during surgery and standard of care non-opioids and opioids at days 0-3 after surgery in the absence of unacceptable toxicity. Patients then receive a second liposomal bupivacaine injection on day 4 after surgery.

After completion of study treatment, patients are followed up at 1, 3, and 12 months after the surgery.

Primary Outcome Measures
NameTimeMethod
Initial discharge prescription oral morphine equivalents (OME)At time of discharge (median of 9 days)

Will perform two-sample t-test to compare the mean doses of discharge prescription OME between the two groups. In addition, multiple linear regression analysis will be carried out to assess the difference between the two arms after adjusting for the stratification factors and other patient characteristics at baseline.

Secondary Outcome Measures
NameTimeMethod
Patient reported outcomes for gastrointestinal surgeryUp to 12 months post surgery

Will be captured using MD Anderson Symptom Inventory-Gastrointestinal (MDASI-GI).

Daily inpatient pain scoresAt time of discharge (median of 9 days)

Linear mixed model will be used for continuous outcomes such as daily inpatient pain scores.

30-day total OMEAt 30 days after discharge

Will perform two-sample t-test to compare the 30-day total OME between the two groups. In addition, multiple linear regression analysis will be carried out to assess the difference between the two arms after adjusting for the stratification factors and other patient characteristics at baseline.

Number of postoperative days until zero opioid useUp to 12 months post surgery

Will perform two-sample t-test to compare the number of postoperative days until zero opioid use between the two groups. In addition, multiple linear regression analysis will be carried out to assess the difference between the two arms after adjusting for the stratification factors and other patient characteristics at baseline.

Opioid use at 30 daysAt 30 days post surgery

Logistic regression analyses will be performed.

Opioid use at 3 monthsAt 3 months post surgery

Logistic regression analyses will be performed.

Proportion of patients with zero discharge prescription OMEAt time of discharge (median of 9 days)

Logistic regression analyses will be performed.

Total length of stayAt time of discharge (median of 9 days)

Will perform two-sample t-test to compare the total length of stay between the two groups. In addition, multiple linear regression analysis will be carried out to assess the difference between the two arms after adjusting for the stratification factors and other patient characteristics at baseline.

Initial discharge pain prescription dosage/sizeAt time of discharge (median of 9 days)

Will perform two-sample t-test to compare the initial discharge pain prescription dosage/size between the two groups. In addition, multiple linear regression analysis will be carried out to assess the difference between the two arms after adjusting for the stratification factors and other patient characteristics at baseline.

Patients free of opioid useUp to 1 year post surgery
MDASI-GI at 12 monthsAt 12 months post surgery
MDASI-GI at 30 daysAt 30 days post surgery
MDASI-GI at 3 monthsAt 3 months post surgery
Opioid use at 12 monthsAt 12 months post surgery

Logistic regression analyses will be performed.
