A framework for in-field and out-of-field patient specific secondary cancer risk estimates from treatment plans using the TOPAS Monte Carlo system

Objective. To allow the estimation of secondary cancer risks from radiation therapy treatment plans in a comprehensive and user-friendly Monte Carlo (MC) framework. Method. Patient planning computed tomography scans were extended superior-inferior using the International Commission on Radiological Protection’s Publication 145 computational mesh phantoms and skeletal matching. Dose distributions were calculated with the TOPAS MC system using novel mesh capabilities and the digital imaging and communications in medicine radiotherapy extension interface. Finally, in-field and out-of-field cancer risk was calculated using both sarcoma and carcinoma risk models with two alternative parameter sets. Result. The TOPAS MC framework was extended to facilitate epidemiological studies on radiation-induced cancer risk. The framework is efficient and allows automated analysis of large datasets. Out-of-field organ dose was small compared to in-field dose, but the risk estimates indicate a non-negligible contribution to the total radiation induced cancer risk. Significance. This work equips the TOPAS MC system with anatomical extension, mesh geometry, and cancer risk model capabilities that make state-of-the-art out-of-field dose calculation and risk estimation accessible to a large pool of users. Furthermore, these capabilities will facilitate further refinement of risk models and sensitivity analysis of patient specific treatment options.

A comparative study of the outcome of unilateral versus bilateral internal anal sphincterotomy in treatment of chronic anal fissure

Background: Gold standard treatment for chronic anal fissure is lateral internal sphincterotomy. Bilateral internal sphincterotomy (BIS) as a treatment option for chronic anal fissure has not been evaluated. Aims and Objectives: The aims and objectives of the study are to compare the efficacy of unilateral versus bilateral internal anal sphincterotomy in treatment of chronic anal fissure. Materials and Methods: Study design: A prospective randomized comparative study. Study area: Patients coming to General Surgery outpatient department at College of Medicine and Sagore Dutta Hospital with chronic anal fissure. Study period: July 2022 to December 2023 (18 months). Sample Size: 100 patients. Study Group: Group A=Patients who had undergone unilateral internal sphincterotomy (UIS)=50 patients and Group B=Patients who had undergone BIS=50 patients. Results: 2 (4%) patients in Group A and 3 (6%) patients in Group B developed incontinence for flatus postoperatively. No patients in either group developed incontinence for stools. The Mean Fissure Healing Time (Mean±SD) (Weeks) post-sphincterotomy was 4.32±0.91339 in Group A and 2.66±0.65807 in Group B. There were 6 cases of recurrence in the unilateral sphincterotomy group. Second surgery was needed in 4 patients who underwent unilateral sphincterotomy. Conclusion: As compared to UIS, BIS results in a faster healing of chronic anal fissure, with no increase in incontinence, decreased pain score, and less recurrence rates.

Protective Effects of Huo Xiang Zheng Qi Liquid on Clostridioides difficile Infection on C57BL/6 Mice

Background: Clostridioides difficile-associated disease (CDAD) is a major healthcare-associated infection. New treatment options for CDAD are needed. A traditional Chinese medicinal formula, Huo Xiang Zheng Qi (HXZQ), was chosen to test against CDAD in a mouse model. Methods: C57BL/6 mice were challenged with C difficile (ATCC 43255) orally; then received saline; vancomycin 25 mg/kg; or HXZQ in two different concentrations twice daily for 5 days. The animals’ body weight; clinical signs; and survival rates were registered daily. Fecal pellets from each animal were taken for PCR analysis as a control of infection. Results: 50% of the mice receiving saline died; 85.7% of the mice receiving vancomycin survived; 75% of the mice receiving HXZQ survived; and 87.5% of the mice receiving a 1:1 saline dilution of HXZQ survived. The HXZQ-treated groups were C. difficile PCR positive with loads less than that of the untreated mice. The weight loss in the vancomycin plus HXZQ 1:1 treated group; the vancomycin-treated group; and the untreated group were 3.08%, 4.06%, and 9.62%, respectively. Conclusions: our results showed that HXZQ can protect mice from CDAD-related death as effectively as vancomycin and the combination of vancomycin and HXZQ may give even better protection.

T Cell-Engaging Bispecific Antibodies Targeting gp100 and PRAME: Expanding Application from Uveal Melanoma to Cutaneous Melanoma

Uveal melanoma represents a rare and aggressive subtype of melanoma with limited treatment options and poor prognosis, especially in the metastatic setting. Tebentafusp, a bispecific fusion protein, offers a promising therapeutic approach by targeting gp100, an antigen highly expressed in uveal melanoma cells, and redirecting T cell-mediated cytotoxicity towards tumor cells. This review provides an overview of the preclinical and clinical data on tebentafusp in the management of metastatic uveal melanoma. We summarize the mechanism of action, clinical efficacy, safety profile, and ongoing research efforts surrounding this innovative immunotherapy. Preclinical studies have demonstrated the ability of tebentafusp to induce potent and specific anti-tumor immune responses against gp100-expressing uveal melanoma cells. Clinical trials have shown encouraging results, with tebentafusp exhibiting meaningful clinical activity in a subset of patients with metastatic uveal melanoma. Importantly, tebentafusp has also demonstrated a manageable safety profile. By specifically targeting tumor cells expressing gp100, tebentafusp offers a promising therapeutic avenue for individuals with metastatic uveal melanoma, meeting a significant clinical need in this context. Continued clinical trials will provide additional insights into the impact of tebentafusp on treatment-resistant metastatic cutaneous melanoma. Furthermore, we are exploring the potential of T cell engagers directed against the cancer testis antigen PRAME, which could have widespread utility in the treatment of cutaneous melanoma as well as other PRAME-expressing malignancies.

Structural Characterization of Human Bufavirus 1: Receptor Binding and Endosomal pH-Induced Changes

Bufaviruses (BuV) are members of the Parvoviridae of the Protoparvovirus genus. They are non-enveloped, T = 1 icosahedral ssDNA viruses isolated from patients exhibiting acute diarrhea. The lack of treatment options and a limited understanding of their disease mechanisms require studying these viruses on a molecular and structural level. In the present study, we utilize glycan arrays and cell binding assays to demonstrate that BuV1 capsid binds terminal sialic acid (SIA) glycans. Furthermore, using cryo-electron microscopy (cryo-EM), SIA is shown to bind on the 2/5-fold wall of the capsid surface. Interestingly, the capsid residues stabilizing SIA binding are conserved in all human BuVs identified to date. Additionally, biophysical assays illustrate BuV1 capsid stabilization during endo–lysosomal (pH 7.4–pH 4) trafficking and capsid destabilization at pH 3 and less, which correspond to the pH of the stomach. Hence, we determined the cryo-EM structures of BuV1 capsids at pH 7.4, 4.0, and 2.6 to 2.8 Å, 3.2 Å, and 2.7 Å, respectively. These structures reveal capsid structural rearrangements during endo–lysosomal escape and provide a potential mechanism for this process. The structural insights gained from this study will add to the general knowledge of human pathogenic parvoviruses. Furthermore, the identification of the conserved SIA receptor binding site among BuVs provides a possible targetable surface-accessible pocket for the design of small molecules to be developed as anti-virals for these viruses.

Posterior Spinal Fusion for Severe Kyphosis in a Child with Gaucher Disease: A Case Report and Review of the Literature

Background: Skeleton involvement is one of the most significant aspects of Gaucher disease (GD). However, the treatment for spinal involvement in GD among patients undergoing enzyme replacement therapy (ERT) is poorly characterized. We present a case of progressive kyphotic spinal deformity in a young child caused by vertebral involvement, which was managed by posterior spinal fusion without anterior spinal release under ERT. Case presentation: This is a retrospective study. A 10-year-old boy presenting with progression kyphosis (thoracic kyphotic angle of 113°) associated with type-IIIb GD had undergone posterior spinal fusion with segmental pedicle screw fixation (from T6-L3) and Ponte osteotomy. The patient went back to school without further brace protection. Proximal junctional kyphosis (PJK) was observed at 4 months postoperatively. Revision surgery was performed to prevent neurological impairment. Additional posterior spinal fusion from T2–T6 and decompressive laminectomy were performed during the revision surgery. A 2-year follow-up showed no recurrence of PJK and solid fusion was achieved in the patient under ERT and brace protection. Conclusions: Posterior spinal fusion without anterior spinal release is a good treatment option for severe spinal deformity in patients with GD. However, the fusion level and reinforced fixation require careful consideration. Revision surgery and brace protection is needed as long as PJK is observed.

A comprehensive investigation of biochemical status in patients with telogen effluvium: Analysis of Hb, ferritin, vitamin B12, vitamin D, thyroid function tests, zinc, copper, biotin, and selenium levels.

The etiology of telogen effluvium (TE) includes situations that may cause physiological stress, surgical trauma, inflammatory, infectious, iatrogenic causes, medications and nutritional deficiencies. TE has been associated with iron deficiency, vitamin B12 deficiency and thyroid diseases. In recent years, the use of over-the-counter food supplements containing vitamins and minerals such as biotin, vitamin D, zinc (Zn), copper (Cu) and selenium (Se) has been increasing in TE patients. The aim of this study is to investigate whether there are differences in nutritional status, vitamin and mineral levels by comparing individuals with TE and a control group. This case-control study included 90 female patients diagnosed with chronic telogen effluvium (CTE), and 90 female controls volunteered to participate in the study who consulted for reasons other than TE. Both groups aged 18 and over and applied to dermatology polyclinic between 01.09.2022 and 01.09.2023. A detailed anamnesis was taken from all patients, a hair pull test was performed, and TE was diagnosed after a dermoscopic examination was performed on all areas of the scalp. Then, serum vitamin D, Zn, Cu, Se levels and biotin levels in serum and urine were measured. Hemoglobin (Hb), ferritin, vitamin B12 and thyroid function tests were retrospectively scanned from the hospital database. It was determined that Zn levels were significantly lower in CTE patients than in controls. Se levels were found to be significantly higher in patients than in controls. There was no difference in Hb, ferritin, vitamin B12, thyroid function tests, vitamin D, Cu levels, serum and urine biotin levels between the two groups. Zn, Cu/Zn and Se levels were found to have statistically significant diagnostic performance in predicting the diagnosis of CTE. Cu/Zn ratio and Se value were found to be significant predictors of CTE. This study shows us that nutritional deficiencies are not as common as thought in patients diagnosed with TE. Other causes that may cause TE should be investigated by a detailed anamnesis and a good physical examination. After all, tests for suspected conditions should be performed and individualized treatment options should be created for each patient.

Treatment concepts for the medial clavicle and the sternoclavicular joint

Medial clavicle fractures and injuries to the sternoclavicular joint are rare injuries but can have life-threatening consequences. There are no standardized treatment algorithms or guidelines for the diagnostics and treatment. This article provides an overview of the individual topographies as well as the conservative and surgical treatment strategies.Conservative treatment is preferred for medial clavicle fractures. The indications for surgical treatment are variable but this is frequently carried out if there is a fracture displacement > 1 cm or1 shaft width and high functional demands. In the case of accompanying injuries to neurovascular structures, an open fracture or the threat of perforation of the skin, surgical treatment is mandatory. Open reduction and internal fixation using (locking) plates is currently the preferred form of treatment.In the case of posterior dislocation of the sternoclavicular joint, an immediate closed reduction must be attempted with the patient under analgosedation and with emergency treatment on standby. This temporal urgency does not exist for anterior and superior dislocations. Surgical treatment is indicated in cases of unsuccessful reduction, persistent symptomatic instability or injuries of the neurovascular bundle. From a multitude of treatment options, arthrodesis with suture cerclage has shown good results. Tendon grafts as well as special hook plates are increasingly being used due to better biomechanical qualities. The surgical treatment of combined injuries is determined by the individual injury pattern.Despite the variety of treatment strategies, the long-term outcome has consistently been positively described.

Comparative Evaluation of the Short-Term Outcome of Different Endovascular Aortic Arch Procedures

Objectives: There are several endovascular treatment options to treat aortic arch and thoracic aortic pathologies with custom-made or surgeon-modified aortic stent grafts. This study seeks to assess endovascular treatment methods for aortic arch and thoracic aortic pathologies with no acceptable proximal landing zone for standard thoracic endovascular aortic repair (TEVAR), comparing different treatment methods and evaluating technical success, intraoperative parameters and short-term outcomes. Methods: All patients undergoing elective or emergency endovascular treatment of aortic arch and thoracic aortic pathologies, with no acceptable landing zone for standard TEVAR, between 1 January 2010 and 31 March 2024, at the University Hospital Düsseldorf, Germany were included. An acceptable landing zone was defined as a minimum of 2 cm for sufficient sealing. All patients were not suitable for open surgery. Patients were categorized by an endovascular treatment method for a comprehensive comparison of pre-, intra- and postoperative variables. IBM SPSS29 was used for data analysis. Results: The patient cohort comprised 21 patients, predominantly males (81%), with an average age of 70.9 ± 9 years with no acceptable proximal landing zone for standard TEVAR procedure. The most treated aortic pathologies were penetrating aortic ulcers and chronic post-dissection aneurysms. Patients were sub-grouped according to the applied procedure as follows: five patients with chimney thoracic endovascular aortic repair (chTEVAR), seven patients with in situ fenestrated thoracic endovascular aortic repair (isfTEVAR), six patients with custom-made fenestrated thoracic endovascular aortic repair (cmfTEVAR) and three patients with custom-made branched thoracic endovascular aortic repair (cmbTEVAR). Emergency procedures involved two patients. There were significant differences in the total procedure and fluoroscopy time, as well as in contrast agent usage among the treatment groups. cmfTEVAR had the shortest total procedure time, while chTEVAR exhibited the highest contrast agent usage. The overall mortality rate among all procedures was 9.5% (two patients) and 4.7% for elective procedures, respectively. Deaths were associated with either retrograde type A dissection or stent graft infection. Both patients were treated with chTEVAR. There was one minor and one major stroke; these patients were treated with isfTEVAR. No endoleak occurred during any procedure. The reintervention rate for chTEVAR was 20% and 0% for all other procedures during the in-hospital stay. The patients who were treated with cmfTEVAR had no complications, the shortest operating and fluoroscopy time, and less contrast agent was needed in comparison with other treatment methods. Conclusions: Complex endovascular procedures of the aortic arch with custom-made or surgeon-modified aortic stent grafts offer a safe solution, with acceptable complication rates for patients who are not suitable for open aortic arch repair. In terms of procedure-related parameters and complication rates, a custom-made fenestrated TEVAR is potentially advantageous compared to the other endovascular techniques.

Constipation and DIOS: Diagnosis, differential diagnosis, and management.

Cystic Fibrosis (CF) is a complex disorder that requires multidisciplinary expertise for effective management. The GALAXY study estimated the prevalence of constipation to be about 25% among People with Cystic Fibrosis (PwCF), identifying it as one of the common gastrointestinal (GI) symptoms within this patient population. Quality of Life (QoL) assessments uncovered high patient dissatisfaction, highlighting the imperative need for enhanced treatment strategies. Similarly, Distal Intestinal Obstruction Syndrome (DIOS) is a unique condition exclusive to PwCF that, if left undiagnosed, can lead to considerable morbidity and mortality. Given the broad spectrum of differential diagnoses for abdominal pain, including constipation and DIOS, it is paramount for healthcare providers to possess a clear understanding of these conditions. This paper aims to delineate various differentials for abdominal pain while elucidating the pathogenesis, diagnostic criteria, and treatment options for managing constipation and DIOS in PwCF.

Islet transplantation in Korea.

Type 1 diabetes mellitus is characterized by absolute insulin deficiency, which requires life-long insulin replacement. Exogenous multiple-daily insulin injections are most commonly prescribed for patients with type 1 diabetes mellitus. However, exogenous insulin supply often fails to cope with real-time changing life-log variables, such as activity, diet and stress, which results in recurrent hypo- and hyperglycemia in patients with type 1 diabetes mellitus. Islet transplantation is an ideal method to treat patients with type 1 diabetes mellitus, as it can restore the endogenous capacity of glucose-stimulated insulin secretion. However, due to donor scarcity and technical barriers, only a limited number of islet transplantations have been carried out in Asia, including South Korea. Since 2013, our center has carried out two allogenic islet transplantations, with one case leading to near total insulin independence after one-to-one islet transplantation. Although the other patient failed to restore endogenous insulin production, there was a remarkable improvement in hypoglycemia. We speculate that islet transplantation remains an important and ideal treatment option for patients with type 1 diabetes mellitus who suffer from recurrent severe hypoglycemia.

Molecular tumor boards in uro-oncology-prostate cancer

The rapid development of molecular medicine has opened up new perspectives for the diagnosis and treatment of urological tumors. Urology faces the challenge of effectively treating advanced cancer, especially in view of the genetic diversity of urological tumors. The molecular tumor board offers an innovative approach to identify targeted therapy options based on the individual genetic signatures of tumor cells or tumor microenvironment-based treatment options. In this article, the concept of the molecular tumor board in urology is presented using the example of prostate cancer. We discuss the principles, applications, and future prospects of this promising approach.

Effects of L-Ornithine-L-Aspartate on Angiogenesis and Perfusion in Subacute Hind Limb Ischemia: Preliminary Study

The current treatment options for peripheral arterial disease (PAD) are limited due to a lack of significant high-level evidence to inform clinical decisions and unfavorable outcomes in terms of cost-effectiveness and amputation rates. In order to suggest the use of the commercially available L-Ornithine-L-Aspartate (LOLA) for treating PAD, we induced hind limb ischemia (HLI) by unilaterally ligating the femoral artery in a rat model. The rats were randomly divided into three groups, with seven rats assigned to each group: group 1 (control), group 2 (sorbitol), and group 3 (LOLA). Intraperitoneal injections were administered five times on post-operative days (PODs) 3, 5, 7, 10, and 12. Perfusion imaging was conducted on PODs 7 and 14 and compared to pre-operative perfusion imaging. Immunohistochemistry staining and Western blotting were performed after the final perfusion imaging. Group 3 showed a significant increase in perfusion, high CD31-positive capillary lumen density, and substantial overexpression of VEGF in the ischemic limb during the subacute phase of HLI. In conclusion, this study provides the first documented evidence of angiogenesis and perfusion recovery in the subacute phase of the HLI model following the administration of LOLA. With LOLA readily available on the commercial market, the implementation of LOLA treatment for PAD in humans can be expedited compared to other therapies still in the developmental stage.

The Potential of Fish Oil Components and Manuka Honey in Tackling Chronic Wound Treatment

Chronic wounds are becoming an increasing burden on healthcare services, as they have extended healing times and are susceptible to infection, with many failing to heal, which can lead ultimately to amputation. Due to the additional rise in antimicrobial resistance and emergence of difficult-to-treat Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp. (ESKAPE pathogens), novel treatments will soon be required asides from traditional antibiotics. Many natural substances have been identified as having the potential to aid in both preventing infection and increasing the speed of wound closure processes. Manuka honey is already in some cases used as a topical treatment in the form of ointments, which in conjunction with dressings and fish skin grafts are an existing US Food and Drug Administration-approved treatment option. These existing treatment options indicate that fatty acids from fish oil and manuka honey are well tolerated by the body, and if the active components of the treatments were better understood, they could make valuable additions to topical treatment options. This review considers two prominent natural substances with established manufacturing and global distribution—marine based fatty acids (including their metabolites) and manuka honey—their function as antimicrobials and how they can aid in wound repair, two important aspects leading to resolution of chronic wounds.

Yoga as a Potential Tool for Filling Implementation Gap in Promoting Better Mental Health in Geriatric Age Group at Global Level: A Scoping Review

This scoping review aims to review the effectiveness of yoga as a complementary intervention for improving mental health outcomes in the geriatric population globally. Yoga is practiced by millions worldwide. Since practitioners of yoga claim to have calmer minds and better psychological and physical health, this topic needs to be reviewed at length. There is a considerable treatment gap worldwide in treating mental disorders, especially in old age, and there is a shortage of low-cost, feasible, and acceptable preventive or treatment options available to tackle mental ailments for the senior population at large. Yoga can potentially act as a low-cost intervention for promoting better mental health. The article reviews yoga as an implementation strategy for meeting this global challenge. Information related to “Yoga and Mental Health” and “Yoga and old age” was searched in two databases, i.e., PubMed and Google Scholar, using a standard search strategy and search strings. Only the articles published in the English language were selected. A standard data extraction form was used to extract and tabulate the data. A comprehensive search strategy (annexed) yielded only two papers as the work on implementation research on mental health is dismal. Both were excluded as the papers did not belong to implementation research. However, for the sake of narrative review, a common search strategy in PubMed included key terms such as “yoga and aging and mental health” and yielded 54 results out of which 7 were included for this scoping review. Comprehensive advanced search from Google Scholar revealed 4850 articles. Screening found 1 implementation research abstract only and two clinical trials. None was included as they did not belong to implementation research. Considering the potential that yoga has as a preventive and therapeutic option, scientific work on implementation research involving mental health and yoga is required. Considering the bludgeoning amount of work done on the subject, there is a possibility of including the same in mainstream medicine as a low-cost preventive or therapeutic option to address the implementation gap in mental health, especially for the senior age group.

Novel Antimitotic Agent SP-1-39 Inhibits Head and Neck Squamous Cell Carcinoma.

Effective management of head and neck cancer (HNC) poses a significant challenge in the field of oncology, due to its intricate pathophysiology and limited treatment options. The most common HNC malignancy is head and neck squamous cell carcinoma (HNSCC). HNSCC treatment includes a combination of surgery, radiation, and chemotherapy. While HNSCC is treatable if diagnosed early, this is often not the case and is considered incurable once in its late stages and metastatic disease has developed. Therapies are also limited once resistant disease has occurred. SP-1-39, a novel colchicine-binding site inhibitor (CBSI), has been recently reported for its potential efficacy in a variety of cancer cell lines including breast, melanoma, pancreatic, and prostate. SP-1-39 also shows abilities to overcome paclitaxel resistance in a paclitaxel-resistant prostate cancer xenograft model. To evaluate the potential of SP-1-39 as a new HNSCC treatment option, herein we systematically performed preclinical studies in HNSCC models using SP-1-39 and demonstrated that, in vitro, SP-1-39 inhibits the proliferation of 2 HNSCC cell lines with low nanomolar IC50 values (1.4 to 2.1 nM), induces HNSCC cell apoptosis in a dose-dependent manner, interferes with migration of HNSCC cells, and leads to HNSCC cell cycle arrest in the G2/M phase. In vivo, SP-1-39 suppresses the primary tumor growth of a Detroit 562 subcutaneous xenograft mouse model in 6- to 8-wk-old, male NSG (NOD.Cg-Prkdcscid Il2rgtm1Wjl/SzJ) mice, with no detectable cytotoxic effects at a low dose of 2.5 mg/kg. This efficacy of SP-1-39 is better when compared with the treatment using a reference chemotherapy drug, paclitaxel at 10 mg/kg. Collectively, these data demonstrate that SP-1-39 is a promising candidate for further development for more efficacious HNSCC treatment.

NRG1 Gene Fusions—What Promise Remains Behind These Rare Genetic Alterations? A Comprehensive Review of Biology, Diagnostic Approaches, and Clinical Implications

Non-small cell lung cancer (NSCLC) presents a variety of druggable genetic alterations that revolutionized the treatment approaches. However, identifying new alterations may broaden the group of patients benefitting from such novel treatment options. Recently, the interest focused on the neuregulin-1 gene (NRG1), whose fusions may have become a potential predictive factor. To date, the occurrence of NRG1 fusions has been considered a negative prognostic marker in NSCLC treatment; however, many premises remain behind the targetability of signaling pathways affected by the NRG1 gene. The role of NRG1 fusions in ErbB-mediated cell proliferation especially seems to be considered as a main target of treatment. Hence, NSCLC patients harboring NRG1 fusions may benefit from targeted therapies such as pan-HER family inhibitors, which have shown efficacy in previous studies in various cancers, and anti-HER monoclonal antibodies. Considering the increased interest in the NRG1 gene as a potential clinical target, in the following review, we highlight its biology, as well as the potential clinical implications that were evaluated in clinics or remained under consideration in clinical trials.

Giant Atypical Spindle Cell Lipomatous Tumor of Retroperitoneal Origin Presenting with Lung Metastasis and Extension to the Thigh: A Case Report with Literature Review

AbstractRetroperitoneal liposarcomas are rare, and their variants, atypical spindle cell lipomatous tumor (ASCLT), are rarer. Though ASCLTs are benign, they have high recurrence despite complete surgical excision. We present a rare case of a 22-year-old male presented with insidious-onset, and gradually progressive swelling over left inguinofemoral, and iliac fossa region. Also, the patients had a history of weight loss, pricking-type pain radiating to left lower limb, and breathlessness on exertion. Contrast-enhanced computed tomography (CECT) abdomen revealed a large well-defined heterogeneously enhancing soft mass located in pelvis, and involving left-sided iliopsoas muscle suggestive of retroperitoneal soft tissue sarcoma and CECT thorax showed metastasis. The CT-guided core biopsy led to the definitive diagnosis of low-grade ASCLT. Subsequently, the patient was initiated on concurrent neoadjuvant chemoradiotherapy followed by complete surgical excision. The findings in this report make it critical to enhance our understanding of this rare tumor, with surgery being the best treatment option.
