Functional Liver Imaging With Sulfur Colloid SPECT/CT in Primary and Metastatic Liver Cancer Patients Receiving Liver-Directed Treatment: A Pilot Study

This pilot trial studies how well single photon emission computed tomography (SPECT)/computed tomography (CT) with technetium Tc-99m sulfur colloid works in measuring liver function in patients with liver cancer that has or has not spread to other place in the body who are undergoing radiation therapy or surgery. Diagnostic procedures, such as sulfur colloid SPECT/CT scans, may measure normal liver tissue before, during and after treatment and help doctors plan better treatment for liver cancer patients.

Personalized Radiation Therapy Through Functional Lung Avoidance and Response-Adaptive Dose Escalation: Utilizing Multimodal Molecular Imaging to Improve the Therapeutic Ratio (FLARE RT)

This phase II trial studies how well positron emission tomography (PET)/computed tomography (CT) and single positron emission computed tomography (SPECT)/CT imaging works in improving radiation therapy treatment in patients with stage IIB-IIIB non-small cell lung cancer. PET/CT imaging mid-way through treatment may be able to accurately show how well radiation therapy and chemotherapy are working. SPECT/CT imaging may be able to tell which parts of the lung tissue are healthier than others. Based on the result of the imaging, treatment adjustments may be made to the radiation therapy to improve survival and decrease toxicity.

Combined Techniques of Non-invasive 99mTcBesilesomab/ 99mTc-Sulfur Colloid with Hybrid SPECT/CT Imaging in Characterising Cellulitis from Symptomatic Perimegaprosthetic Infection: A Case Report

Author: Faisham, W I ; Wan-Sohaimi, W F ; Mohd-Rohani, M F ; Nawi, N M ; Tagiling, N

Megaprosthesis is used to restore the form and function of massive skeletal defects, but it is accompanied by risks of failure, mainly due to perimegaprosthetic infection (PMI). In practice, the diagnosis of infected megaprosthesis among patients with a high index of clinical suspicion, elevated serological markers, and multiple negative or inconclusive imaging can be very challenging and poses a diagnostic conundrum to many orthopaedic surgeons. We present the case of a symptomatic 26-year-old female with large B-cell lymphoma who developed cellulitis with suspected complication of PMI 15 months post-implantation. The combination of advanced nuclear medicine imaging strategies, i.e., ^99mTc-besilesomab/^99mTc-sulfur colloid scintigraphy with hybrid single-photon emission computed tomography/computed tomography (SPECT/CT) scanning helps to characterise and delineate both infections. Invasive procedures such as joint aspiration and biopsy were avoided, and the patient was successfully treated with antibiotics. Hence, we report a case where advanced imaging modalities were decisive in the investigation of PMI.

Effect of Topical Anesthetic Cream on Pain During Periareolar Injection of Technetium Tc99m Sulfur Colloid for Sentinel Lymph Node Biopsy in Breast Cancer: A Randomized Control Trial

Article

Author: Suryavanshi, Rajeev ; Canning, Sarah ; Bryson-Campbell, Mikelle

BACKGROUND:

Injection of Tc99m to localize nodes for sentinel lymph node biopsy is reported by patients as very painful. The purpose of this study was to determine if anesthetic cream reduces pain associated with periareolar injection of Tc99m and to help elucidate conflicting literature regarding the efficacy of anesthetic cream for this procedure.

METHODS:

A randomized, double-blind, placebo-controlled methodology was used for adult females with breast cancer undergoing periareolar injection of Tc99m for sentinel lymph node biopsy. Pain levels were compared using anesthetic cream (2.5% lidocaine/2.5% prilocaine) vs. placebo. Patient exclusion criteria included use of opioids or adjuvant pain medication or injecting Tc99m the day before surgery. The Numerical Rating Scale was used to assess pain levels immediately after the injections.

RESULTS:

Comparing 23 experimental and 26 control patients, there was no significant difference between the experimental (median = 4) and the control group (median = 5) on level of pain experienced U= 0.492, P > .05.

CONCLUSIONS:

The experimental group had a slightly lower median pain score; however, there was no statistically significant difference between those who used the cream compared with those who used a placebo, supporting the conclusion that anesthetic cream does not reduce pain during Tc99m injections. This study adds to the current literature to provide a stronger position that there is no benefit to using anesthetic cream for this procedure.

Tc‐99m tilmanocept versus Tc‐99m sulfur colloid in breast cancer sentinel lymph node identification: Results from a randomized, blinded clinical trial

Article

Author: Unkart, Jonathan T. ; Hosseini, Ava ; Wallace, Anne M.

Introduction:

No prior trials have compared sentinel lymph node (SLN) identification outcomes between Tc‐99m tilmanocept (TcTM) and Tc‐99m sulfur colloid (TcSC) in breast cancer (BC).

Methods:

We report on the secondary outcomes from a randomized, double‐blinded, single surgeon clinical trial comparing post‐injection site pain between TcTM and TcSC. Patients were randomized to receive a preoperative single, peritumoral intradermal injection of TcTM or TcSC. The number of total, “hot”, and blue nodes detected and removed were compared between groups.

Results:

Fifty‐two (27‐TcSC and 25‐TcTM) patients were enrolled and underwent definitive surgical treatment. At least one “hot” SLN was detected in all patients. Three (5.8%) patients had a disease positive‐SLN. The total number of SLNs removed was 61 (mean 2.26 (standard deviation (SD) 0.90)) in the TcSC group and 54 (mean 2.16 (SD 0.90)) in the TcTM group, P = 0.69. The total number of “hot” nodes in the TcSC group was 1.96 (SD 0.76) compared to 2.04 (SD 0.73) in the TcTM group, P = 0.71.

Conclusions:

The number of identified SLNs did not differ significantly between TcTM and TcSC. Given that no significant technical advantages exist between the two agents, surgeons should choose a radiopharmaceutical based on cost and side effect profile.
