RESUMEN

Objective: To compare costs between treatment strategies employed prior to and after prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) via the Brazilian Unified Health Care System and their impact on the therapeutic management of biochemical recurrence of prostate cancer. Materials and Methods: The referring physicians were surveyed on their treatment intentions (strategies) at two different time points: prior to and after PSMA PET/CT. Cost comparison results are presented as median (IQR) for each of the two strategies. The shift in therapeutic management after PSMA PET/CT was also analyzed. Results: The study sample included 59 patients (mean age: 65.9 years). The PSMA PET/CT result was considered positive in 38 patients (64.4%) and was found to have an impact on the treatment strategy in for 36 patients (61.0%). Prior to PSMA PET/CT, salvage therapy (i.e., treatment with curative intent) was the intended treatment for most patients, and that was significantly less so after the examination (76.3% vs. 45.8%; p < 0.001). Conversely, a strategy involving systemic (i.e., palliative) therapy became more common after PSMA PET/CT (23.7% vs. 54.2%; p < 0.001). The after-PSMA PET/CT strategy presented higher overall costs than did the before-PSMA PET/CT strategy, in all scenarios evaluated. In all scenarios, nearly half of this cost difference was related to the cost of the PSMA PET/CT itself, the remainder being related to the new treatment choices that stemmed from knowledge of the PSMA PET/CT findings. Conclusion: For patients treated within the Brazilian Unified Health Care System, PSMA PET/CT presented higher costs in comparison with conventional imaging methods. Adding PSMA PET/CT to the workflow had an impact on therapeutic management, mainly representing a shift from futile curative treatments to systemic palliative ones. The amount of funds that could potentially be saved by not providing such futile treatments would suffice to evaluate roughly two patients with PSMA PET/CT scans for each futile treatment strategy avoided.


Objetivo: Comparar custos entre estratégias antes e após o exame de PET/CT-PSMA da perspectiva do Sistema Único de Saúde e seu impacto no manejo terapêutico para pacientes com recidiva bioquímica de câncer de próstata. Materiais e Métodos: Os médicos solicitantes informaram a intenção terapêutica em dois momentos: antes e após o exame. Os resultados de comparação de custo estão apresentados como medianas de custo (p25; p75). A mudança na intenção terapêutica também foi analisada. Resultados: O estudo envolveu 59 pacientes (idade média: 65,9 anos). A PET/CT-PSMA foi considerada positiva em 38 dos 59 pacientes (64.4%). O exame impactou a estratégia de tratamento para 36 pacientes (61%). Antes da obtenção das informações da PET/CT-PSMA, a terapia de resgate (i.e., com intenção curativa) era o tratamento sugerido para a maioria dos pacientes, e após o exame, reduziu significativamente (76,3% vs 45,8%; p < 0,001). Em contrapartida, a terapia sistêmica (i.e., paliativa) aumentou como intenção de tratamento após o exame (23,7% vs 54,2%; p < 0,001). A estratégia "após PET/CT-PSMA" apresentou maiores custos em relação à estratégia "antes da PET/CT-PSMA" nos cenários comparados. Cerca de metade da diferença de custos entre as duas estratégias foi relacionada aos custos do exame propriamente ditos, enquanto a outra metade foi relacionada às novas escolhas de tratamento a partir do exame. Conclusão: Oferecer a PET/CT-PSMA no Sistema Único de Saúde apresentou maiores custos em relação à estratégia com métodos de imagem convencionais e impactou o manejo terapêutico, pelo favorecimento de tratamentos sistêmicos paliativos no lugar de tratamentos curativos fúteis. A quantidade de recursos que poderiam ser poupados ao evitar tratamentos fúteis seria suficiente para avaliar aproximadamente dois pacientes com exames de PET/CT-PSMA para cada estratégia de tratamento fútil evitada.

RESUMEN

Gastrointestinal stromal tumors (GISTs) are the most frequent mesenchymal neoplasms of the gastrointestinal (GI) tract. Although surgery is the treatment of choice in resectable disease, neoadjuvant therapy is indicated in advanced, metastatic, and recurrent tumors. Decreasing tumor burden may facilitate resection and reduce surgical morbidity. We describe a case of a 66-year-old male with a recurrent duodenal GIST, after surgery and adjuvant imatinib five years before. Following neoadjuvant therapy with imatinib for 12 months, the patient underwent a cephalic pancreaticoduodenectomy, without complications. The final histopathology showed a pathological complete response (pCR) with no residual neoplasm. A pathological complete response to imatinib in a recurrent disease is extremely rare. Molecular testing should be performed before neoadjuvant therapy to identify response-predictive mutations. In recurrent/metastatic disease, systemic therapy is the standard treatment for all patients. Surgery should be considered in a tailored approach in patients with good responses to systemic therapy before developing therapeutic resistance.

RESUMEN

BACKGROUND: Although two recent phase III randomized controlled trials showed survival benefits of undergoing secondary cytoreductive surgery for an initial relapse of ovarian cancer, patients who received a poly-ADP ribose polymerase inhibitor (PARPi) as the first-line maintenance treatment, which is currently the standard treatment for advanced ovarian cancer, were not included in those trials. Therefore, determining an optimal treatment strategy, including secondary cytoreductive surgery, in patients whose cancer progresses even with PARPi treatment, is needed. PRIMARY OBJECTIVE: To determine whether secondary cytoreductive surgery is beneficial in patients who have progressed on PARPi maintenance treatment. STUDY HYPOTHESIS: Secondary cytoreductive surgery followed by chemotherapy is superior to chemotherapy alone for patients who have progressed on PARPi maintenance treatment. TRIAL DESIGN: The SOCCER-P study is a multicenter randomized phase II clinical trial. Patients who meet the eligibility criteria will be randomized to either undergo secondary cytoreductive surgery and subsequent platinum-based chemotherapy plus or minus bevacizumab, or to receive platinum-based chemotherapy plus or minus bevacizumab alone. Patients randomly allocated to the surgery group will undergo secondary cytoreductive surgery followed by six cycles of a physician's choice of platinum-based chemotherapy once they have recovered from surgery. MAJOR INCLUSION/EXCLUSION CRITERIA: The major inclusion criteria are as follows: first recurrence of disease with treatment-free interval from last platinum dose (TFIp) ≥6 months and progression during PARPi maintenance or treatment-free interval from last PARPi therapy (TFIPARPi) <3 months. The major exclusion criteria are as follows: >1 line of prior chemotherapy, TFIp <6 months, and radiological signs suggesting metastases not accessible to surgical removal (complete resection is deemed not possible). PRIMARY ENDPOINT: Progression-free survival. SAMPLE SIZE: 124 patients. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: Accrual completion approximately the end of 2026 and the results are expected after 2 years of follow-up in 2029. TRIAL REGISTRATION: NCT05704621.

RESUMEN

BACKGROUND: Early detection of soft tissue sarcoma (STS) recurrence is essential; however, the role and timeline of Magnetic resonance imaging (MRI) surveillance are still under debate. The aim of this study was to determine whether local recurrence (LR) could be identified via clinical examination alone and to assess the MRI morphology of primary STS and LR. METHODS: This retrospective study included all patients with STS recurrence after surveillance for at least five years from the tumor database of the Medical University of Vienna from 2000 until December 2023. The characteristics of primary STS and LR and the time interval to recurrence and clinical detectability were assessed. The MRIs of LR and posttherapeutic changes (PTC) were compared with the initial MRIs. RESULTS: A total of 57 patients (60% male; mean age 58.5 ± 18.0 years) with STS and histologically confirmed LR were included. The mean time interval to LR was 2.3 ± 1.8 years (range 108 to 3037 days). The clinically detectable recurrences were significantly larger than the inapparent ones (71.9 cm3 vs. 7.0 cm3; p < 0.01). The MRI morphology of all LRs (26/26) closely resembled the initial STS. For comparison, nine patients were included with clinically suspected LRs, which were histologically proven to be PTC. None of these resembled the primary STS. CONCLUSION: Based on clinical symptoms alone, especially small and early recurrences can be missed, which supports the importance of MRI surveillance.

RESUMEN

Objectives: This study aimed to characterize the demographic and clinical features of patients with renal cell carcinoma (RCC) post-surgery for localized or locally advanced disease in a national Danish cohort, with a specific focus on describing recurrence patterns in a subgroup aligned with the adjuvant KEYNOTE-564 trial classification. Methods: This was a retrospective analysis of the Danish Renal Cancer (DaRenCa) database. Eligible subjects were individuals with an RCC diagnosis between January 2014 and December 2017 who subsequently underwent radical or partial nephrectomy. Variables of interest were demographic and clinical characteristics, rates and sites of recurrence. Recurrence rates were also assessed in a subpopulation stratified using the risk classifications of the KEYNOTE-564 trial. Results: A total of 2164 RCC patients were identified. Most patients (84.8%) had non-metastatic RCC (stage M0). A recurrence was observed in 250 of the M0 patients (13.6%). Patients with a recurrence were older, male, had a higher tumour stage, had undergone radical nephrectomy and had a higher Leibovich score. The majority (74.8%) of M0 patients had recurrence at distant metastatic sites. A total of 392 patients were stratified by the KEYNOTE-564 risk classification: 335 intermediate-high risk, 17 high risk and 40 M1 NED (metastatic with no evidence of disease). Recurrence was observed in 37.0%, 88.2% and 27.5% of these risk groups, respectively. Conclusions: This study elucidates the rates and determinants of post-surgical RCC recurrence in Denmark, underscoring the potential of adjuvant immunotherapy in refining therapeutic strategies, identifying suitable beneficiaries and minimizing overtreatment risks in RCC care.

RESUMEN

Objective: Pulmonary artery sarcoma (PAS) is an exceedingly rare and insufficiently investigated disease, leading to uncertain in its optimal management. This study aims to present our institutional experience and the outcomes of pulmonary endarterectomy for PAS. Methods: We gathered clinical characteristics, intraoperative data, postoperative outcomes, and prognosis information from PAS patients who underwent surgical treatment at our institution between December 2016 and September 2023. Results: A total of 20 patients with PAS underwent pulmonary endarterectomy. The median age of the patients was 52 (IQR 45, 57) years, with 12 patients (60%) being female. Intimal sarcoma was confirmed in 19 patients, while the remaining one was diagnosed with large cell neuroendocrine carcinoma. The perioperative mortality rate was three cases (15%). Follow-up was conducted for a median duration of 14 months (range: 1-61). During the follow-up period, 11 patients experienced recurrence or metastasis, and 5 patients succumbed to the disease. The estimated cumulative survival rates at 1 and 2 years for all 20 patients were 66.4% and 55.3%, respectively. Conclusion: Pulmonary endarterectomy emerges as a palliative but effective approach for managing PAS, particularly when complemented with postoperative therapies such as chemotherapy and targeted therapy, which collectively contribute to achieving favorable long-term survival outcomes.

RESUMEN

Non-cutaneous squamous cell carcinoma (ncSCC) is a rare malignancy, especially involving the orbital and lacrimal apparatus. Hereby, we present a case of recurrence of squamous cell carcinoma (SCC) in the left orbit after excision of lacrimal sac SCC and radiotherapy. She presented with acute painful visual impairment with a frontal headache, with imaging showing medial extraconal and intraconal mass. After confirmation of SCC from the biopsy, modified enucleation was done. However, the patient had a recurrence of SCC, and further debulking was performed with palliative measures. Noteworthy, ncSCC is a rare malignancy with an aggressive nature. Orbital SCC has the worst prognosis compared to conjunctiva or lacrimal sac SCC. Surgery remained the mainstay for higher survival, but chemotherapy and radiotherapy were not associated with a better prognosis, yet there is a lack of data regarding recurrence and its management. In conclusion, ncSCC is a rare and challenging disease that requires timely intervention with multiple disciplinary care, especially when it is spread from the lacrimal sac to the orbital.

RESUMEN

OBJECTIVE: This study aimed to investigate the efficacy and safety of 3-dimensional printing noncoplanar template (3D-PNCT)-assisted computed tomography (CT)-guided high-dose-rate interstitial brachytherapy (HDR-ISBT) for reirradiation of pelvic recurrent cervical carcinoma after external beam radiotherapy. METHODS: From January 2019 to August 2023, 45 eligible patients were enrolled in this prospective cohort. All patients underwent 3D-PNCT-assisted CT-guided HDR-ISBT with a prescribed dose of 4-7 Gy/fraction to the high-risk clinical target volume (HR-CTV) over 3-8 fractions, either for curative or palliative purposes. The primary endpoints were local progression-free survival (LPFS) and tumor response rate (TRR). The secondary outcome measures included overall survival (OS), toxicities, and symptom resolution. RESULTS: Forty-five patients received 261 fractions of 3D-PNCT-assisted HDR-ISBT. Twenty-nine patients had isolated pelvic recurrence, and 16 patients had simultaneous extra-pelvic or distant recurrences. The TRR was 66.7%. The 2- and 5-year LPFS rates were 30.0% and 25.7%, respectively. The median OS was 23.2 months, and 2- and 5-year OS rates were 49.5% and 34.0%, respectively. The multivariate analysis indicated that squamous cell carcinoma, radical surgery, recurrence-free interval≥12 months, tumor diameter, pelvic recurrence type, and HR-CTV D90≥45 Gy were independent factors influencing LPFS (all p<0.05). D100≥21 Gy, V100≥83%, and V150≥45% were associated with better LPFS (all p<0.05). Tumor diameter and metastasis were independent predictive factors for OS (all p<0.05). The pain relief rate was 66.7% (10/15). Grade 3-4 toxicities occurred in 20.0% of patients. CONCLUSION: 3D-PNCT-assisted HDR-ISBT for reirradiation of recurrent cervical cancer proved to be an effective and safe alternative to radical surgery.

RESUMEN

BACKGROUND: Current guidelines do not indicate any comprehensive management of hepatic hypervascular incidentalomas (HVIs) discovered in hepatocellular carcinoma (HCC) patients during intra-arterial therapies (IATs). This study aims to evaluate the prognostic value of HVIs detected on per-interventional cone beam computed tomography (CBCT) during IAT for HCC in patients waiting for liver transplantation (LT). MATERIAL AND METHODS: In this retrospective single-institutional study, all liver-transplanted HCC patients between January 2014 and December 2018 who received transarterial chemoembolization (TACE) or radioembolization (TARE) before LT were included. The number of ≥10 mm HCCs diagnosed on contrast-enhanced pre-interventional imaging (PII) was compared with that detected on per-interventional CBCT with a nonparametric Wilcoxon test. The correlation between the presence of an HVI and histopathological criteria associated with poor prognosis (HPP) on liver explants was investigated using the chi-square test. Tumor recurrence (TR) and TR-related mortality were investigated using the chi-square test. Recurrence-free survival (RFS), TR-related survival (TRRS), and overall survival (OS) were assessed according to the presence of HVI using Kaplan-Meier analysis. RESULTS: Among 63 included patients (average age: 59 ± 7 years, H/F = 50/13), 36 presented HVIs on per-interventional CBCT. The overall nodule detection rate of per-interventional CBCT was superior to that of PII (median at 3 [Q1:2, Q3:5] vs. 2 [Q1:1, Q3:3], respectively, p < 0.001). No significant correlation was shown between the presence of HVI and HPP (p = 0.34), TR (p = 0.095), and TR-related mortality (0.22). Kaplan-Meier analysis did not show a significant impact of the presence of HVI on RFS (p = 0.07), TRRS (0.48), or OS (p = 0.14). CONCLUSIONS: These results may indicate that the treatment plan during IAT should not be impacted or modified in response to HVI detection.

RESUMEN

Metastatic cervical carcinoma from an unknown primary source poses a diagnostic and therapeutic challenge, as it involves the spread of cancer to the neck lymph nodes without a discernible primary tumor despite thorough investigation. While the diagnosis and treatment of this uncommon condition lack definitive evidence, a review of existing literature offers some clinical guidance. A comprehensive diagnostic evaluation, which includes multiple imaging and endoscopic studies, is essential. Surgery is preferred whenever feasible due to its ability to offer more precise staging. This treatment entails an excisional biopsy, neck dissection, and tonsillectomy, but advanced cases necessitate a combination of treatments. This case report underscores this complexity, where, despite radical neck dissection on the affected side, recurrence manifested after two months with no discernible primary site. We emphasize the urgency for continued research and innovative approaches to enhance the diagnosis and management of metastatic cervical carcinoma from an unknown primary source.

RESUMEN

When a mass occurs at the staple line following lung resection, it can be difficult to distinguish between local cancer recurrence and granuloma. We present a case of a staple-line granuloma with 18F-fluorodeoxyglucose-positron emission tomography uptake and elevated serum carbohydrate antigen 19-9 (CA19-9) in a patient with ovarian cancer lung metastasis. After granuloma resection, serum CA19-9 levels normalized, and CA19-9 positive cells were identified in the resected tumor. Therefore, serum CA19-9 elevation does not rule out a staple-line granuloma. Whereas granulomas on computed tomography (CT) scans tend to show smooth shadows along the staple line unilaterally, detailed CT evaluation may help diagnostic differentiation. Differentiation based on imaging and tumor markers has limitations. However, core needle biopsy has the risk of misdiagnosis and tumor cell dissemination, therefore surgical resection should be considered when comprehensive findings indicate a potential recurrence.

RESUMEN

Endometrioid ovarian adenocarcinoma is a common subtype of epithelial ovarian cancer that can arise on a background of endometriosis. Maximal cytoreductive effort with an aim to remove all macroscopic disease (achieve R0) is the single independent prognostic factor for survival. Complex multidisciplinary surgeries may be required in order to achieve this.

RESUMEN

BACKGROUND: A small portion of patients are diagnosed with early gastric cancer (EGC) and undergo endoscopic submucosal dissection (ESD) at a young age. However, their clinical outcomes are rarely known. AIM: We investigated to identify the feasibility and clinical outcomes of ESD for EGC focusing on young patients. METHODS: We analyzed the clinical characteristics and outscomes of patients who had undergone ESD for the treatment of EGC at < 50 years of age. We enrolled patients who had been diagnosed with EGC and had undergone ESD between 2006 and 2020. We divided them by age as follows: ≤ 50 and > 50 years into the young age (YA) and other age (OA) groups, respectively. RESULTS: Altogether, 1681 patients underwent ESD for EGC (YA group: 124 [7.4%], OA group: 1557 [92.6%]). The YA group had less severe atrophy and more undifferentiated (37.1% vs. 13.9%, P < 0.001) and diffuse type (25% vs. 7.7%, P < 0.001) histology. The curative resection rate was not significantly different between the groups. However, among 1075 patients who had achieved curative resection and had been followed-up for > 12 months, the YA group had a lower incidence of MGN (5.2% vs. 17.5%, P = 0.004) and MGC (2.6% vs. 10.9%, P = 0.019) than those exhibited by the OA group. The YA group was a significant negative predictor of MGN (odds ratio [OR]: 2.983, 95% confidence interval [CI] 1.060-8.393, P = 0.038), and marginally negative predictor in MGC (OR: 3.909, 95% CI: 0.939-16.281, P = 0.061). CONCLUSION: ESD is a favorable and effective therapeutic modality for EGC patients aged < 50 years, once curative resection is achieved.

RESUMEN

PURPOSE: Mohs micrographic surgery (MMS) is a low-risk penile cancer management option. However, contemporary patients' short-term oncologic control and preoperative characteristics predicting reconstruction needs are undefined. This study assesses MMS's oncologic efficacy for low-risk penile cancer and identifies baseline predictors of post-resection reconstruction referral. METHODS: We retrospectively reviewed 73 adult males with 78 penile cutaneous malignancies treated with MMS from 2005 to 2019. Patients underwent MMS with or without surgical reconstruction. Demographic information, MMS operative details, lesion pathology, and short-term outcomes were recorded. Descriptive statistics for all variables were calculated, and logistic regression identified predictive factors for urologic referral for complex reconstruction. RESULTS: Seventy-three men with 78 lesions, all staged ≤ cT1a prior to MMS, were identified. Twenty-one men were found to have invasive SCC. Median follow-up was 2.0 years (IQR 0.8-5.2 years). MMS was able to clear the disease in 90.4% of cases. One patient had disease related death following progression. Dermatology closed primarily in 68% of patients. Twenty percent of patients had a complication, most commonly poor wound healing. On univariate and multivariate linear regression analysis, lesion size > 3 cm and involvement of the glans independently predicted the need for referral to a reconstructive surgeon. CONCLUSIONS: MMS for penile cancer appears to provide sound oncologic control in the properly selected patient. Involvement of a reconstructive surgeon may be needed for glandular and large lesions, necessitating early referral to a comprehensive multidisciplinary care team.

RESUMEN

OBJECTIVE: This retrospective, multicenter, observational study aimed to refine patient selection criteria for secondary cytoreductive surgery in recurrent endometrial cancer. The objective was to identify preoperative predictors of complete cytoreduction, assess surgical complexity, and propose a preoperative predictive scoring system to identify suitable candidates for secondary cytoreductive surgery. METHODS: Data from 331 women with recurrent endometrial cancer were analyzed across three Italian centers from January 2010 to December 2021. Patients were categorized based on treatment received (medical treatment, diagnostic laparoscopy/examination under anesthesia, or secondary cytoreductive surgery). Preoperative predictors, surgical complexity, complications, and a predictive scoring system were assessed. Logistic regression and receiver operating characteristic analysis were used for statistical evaluation. RESULTS: Of the cohort, 56.2% underwent debulking surgery, 17.2% had diagnostic laparoscopy, and 26.6% received medical treatment. Patients undergoing secondary cytoreductive surgery were younger, with a lower body mass index, better performance status, and fewer comorbidities. Single site locoregional relapse was common in secondary cytoreductive surgery patients. Age <65 years, single site relapse, lymph node, and hematogenous relapse were independent predictors of complete cytoreduction. A predictive scoring system demonstrated a clear relationship between the score and the likelihood of complete cytoreduction. CONCLUSION: This study identified age <65 years, single site recurrence, as well as nodal and hematogenous recurrence, as predictive factors for achieving optimal cytoreduction. A predictive scoring system incorporating these factors has been proposed to identify optimal candidates for secondary cytoreductive surgery in recurrent endometrial cancer. The scoring system showed promising predictive accuracy and could aid in refining the decision making process, ensuring appropriate patient selection for secondary cytoreductive surgery. Further prospective studies are warranted to validate and enhance the predictive model.

RESUMEN

OBJECTIVES: To examine real-world characteristics, journey, and outcomes among patients with locoregional, nonmetastatic renal cell carcinoma (RCC). METHODS: A retrospective analysis of medical records from the ConcertAI Oncology Dataset was performed on adults in the United States with newly diagnosed nonmetastatic RCC between January 2012-December 2017 who received surgical treatment, and were followed until August 2021. Patients were stratified based on the risk of recurrence after nephrectomy. Recurrence rate and survival outcomes were assessed. RESULTS: The cohort (n = 439) had a median age of 64 years, 66.1% were male, and 76.5% had clear-cell histology. The median follow-up time from nephrectomy was 39.3 months overall, 41.0 months for intermediate-high-risk patients (n = 377; 85.9%) and 24.1 months for high-risk patients (n = 62; 14.1%). For intermediate-high- and high-risk patients, respectively, 68.4% and 56.5% had ≥1 medical oncologist visit after nephrectomy. Of 260 patients with documentation of postoperative imaging assessments, 72% were ordered by medical oncologists, and the median time from initial nephrectomy to the first scan was 110 days (intermediate-high-risk) and 51 days (high-risk). Provider-documented recurrence occurred in 223 (50.8%) patients, of whom 41.7% had ≥1 medical oncologist visit before the recurrence. Three-year disease-free survival (DFS), and overall survival rates were 49.4% and 80.8% (all patients): 27.7% and 64.7% (high-risk); and 52.9% and 83.3% (intermediate-high-risk). CONCLUSIONS: Our study reports low DFS after nephrectomy for patients with intermediate-high- and high-risk RCC. Subsequent approval and use of new and newly approved adjuvant therapeutic options could potentially delay or prevent recurrence.

RESUMEN

Epithelial-myoepithelial carcinoma (EMC) is a rare tumor, characterized by two different cell populations and both demonstrate a malignant nature microscopically. It constitutes less than 2% of all salivary gland malignancies. The World Health Organization (WHO) has classified this disease as a separate pathological category. The diagnosis of this tumor is arrived by biopsy. It shows slow growth and is small in size; it appears in ulcerative form of mucosa in some cases. Gland cells consist of two layers of outer myoepithelium cells and inner epithelial cells. Vimentin staining is positive. It shows calponin, muscle-specific actin, S100, smooth muscle actin, p63, and smooth muscle myosin heavy chain I. Examining different sets of data reveals that tumors exhibiting a solid growth pattern, nuclear atypia, DNA aneuploidy, and increased proliferative activity typically display a more aggressive nature, accompanied by a heightened likelihood of local recurrences and metastases. The clinical and radiological observations frequently resemble those of a benign tumor. Due to the uncommon nature of EMC, there is currently no established standard treatment protocol. It is considered a low-grade tumor where good resection holds better results. Individuals displaying histopathological indicators of aggressive disease should be evaluated for potential adjuvant radiotherapy. We present a case of a patient who had recurrence twice in a period of seven years despite surgical management, chemotherapy, and radiotherapy.
