RESUMO

BACKGROUND: While numerous studies have explored treatment outcomes for the overall ACC patient cohort, data on the subpopulation of patients with recurrent disease are limited. Therefore, the aim of this study was to assess treatment outcomes in patients with recurrent ACC. METHODS: In this retrospective study, we included 18 patients median age 49 years (42-62); 67% female) diagnosed with recurrent ENSAT stage I-III ACC who underwent either R0 (n = 16) or Rx (n = 2) surgical resection of the tumor. RESULTS: The median time from the initial surgery to ACC recurrence was 29 months (IQR 18-50). Seven patients (39%) manifested local recurrence, while 11 patients (61%) developed distant metastases. The median follow-up duration after tumor recurrence was 32 months (IQR 25-53). Regarding the treatment of ACC recurrence, 10 patients underwent a second surgery either as an alone procedure (n = 4), or in combination with mitotane (n = 4), mitotane and chemotherapy (n = 1), or mitotane combined with radiotherapy (n = 1). The remaining patients received treatment involving chemotherapy±mitotane (n = 4) and locoregional therapy ±chemotherapy (n = 3). One patient chose not to proceed with further management and follow-up. The median PFS was 17 (95% CI 8-26) months while the median OS was not reached. In the multivariate model, increased mortality was associated with advanced age (p = 0.04) and a shorter interval to ACC recurrence (p = 0.03). CONCLUSION: A significant proportion of patients with ACC recurrence experience disease progression or second recurrence, despite all treatment efforts. Nevertheless, by integrating diverse treatment modalities, many patients have the potential to attain long-term survival.

RESUMO

Purpose: The goal of the study was to create a nomogram based on clinical risk factors to forecast the rate of locoregional recurrence-free survival (LRFS) in patients with esophageal squamous cell carcinoma (ESCC) who underwent radiotherapy (RT). Methods: In this study, 574 ESCC patients were selected as participants. Following radiotherapy, subjects were divided into training and validation groups at a 7:3 ratio. The nomogram was established in the training group using Cox regression. Performance validation was conducted in the validation group, assessing predictability through the C-index and AUC curve, calibration via the Hosmer-Lemeshow (H-L) test, and evaluating clinical applicability using decision curve analysis (DCA). Results: T stage, N stage, gross tumor volume (GTV) dose, location, maximal wall thickness (MWT) after RT, node size (NS) after RT, Δ computer tomography (CT) value, and chemotherapy were found to be independent risk factors that impacted LRFS by multivariate cox analysis, and the findings could be utilized to create a nomogram and forecast LRFS. the area under the receiver operating characteristic (AUC) curve and C-index show that for training and validation groups, the prediction result of LRFS using nomogram was more accurate than that of TNM. The LRFS in both groups was consistent with the nomogram according to the H-L test. The DCA curve demonstrated that the nomogram had a good prediction effect both in the groups for training and validation. The nomogram was used to assign ESCC patients to three risk levels: low, medium, or high. There were substantial variations in LRFS between risk categories in both the training and validation groups (p<0.001, p=0.003). Conclusions: For ESCC patients who received radiotherapy, the nomogram based on clinical risk factors could reliably predict the LRFS.

RESUMO

OBJECTIVE: There is no consensus on the optimal treatment for patients with locoregional recurrence of esophageal cancer after surgery. The objective of this study was to investigate the outcomes and prognostic factors associated with salvage radiotherapy in patients with locoregional recurrence of esophageal cancer after surgery. METHODS: We reviewed 80 patients with locoregional recurrence of esophageal cancer after surgery who were treated with radiotherapy. The median dose was 60 Gy, and 29 patients (36%) received elective nodal irradiation. Fifty-three patients (66%) received concurrent chemotherapy (mostly 5-fluorouracil and cisplatin) during radiotherapy. Overall survival, progression-free survival and in-field recurrence rate were assessed. RESULTS: The median follow-up period was 17 months. Two-year overall survival, progression-free survival and in-field recurrence rate were 50.3%, 23.5% and 41.3%, respectively. On multivariate analysis, a maximum diameter of locoregional recurrence lesions <30 mm was associated with higher overall survival (P = 0.044). Disease-free interval between surgery and locoregional recurrence >14 months was associated with higher PFS (P = 0.003). Late grade 3 toxicities occurred in three patients (3.8%). No grade 4 or higher toxicity was observed. CONCLUSIONS: Salvage radiotherapy demonstrated efficacy in achieving in-field control with acceptable toxicity. However, the high rate of out-of-field metastases led to poor progression-free survival and overall survival, particularly in cases involving large lesions and a short disease-free interval. A prospective study is warranted to establish a treatment strategy, particularly considering the combined use of effective anti-cancer drugs.

RESUMO

BACKGROUND: The aim of this study was to investigate the patterns of recurrence and their associated risk factors in patients who underwent resection for pancreatic carcinoma. METHODS: This retrospective study included 272 patients, who underwent Ro/R1-resection of PDAC from 2005 to 2020 at the University Hospital Erlangen. Risk factors for different recurrence patterns and the prognostic value of recurrence pattern on the overall survival after recurrence were evaluated. RESULTS: 61 % of the patients experienced recurrence, mostly within the first 12 postoperative months (62 %) and in the form of metastases (87 %). The median overall survival from recurrence was 9.2 months. The preoperative absence of diabetes and the presence of lymph node metastasis were independent risk factors for recurrence and a preoperative CA19-9 exceeding 97 U/ml for early recurrence. Additionally, lymph node metastases were associated with a higher risk of metastatic recurrence. Early recurrence, but not the site of recurrence, was identified as an independent prognostic factor for worse overall survival from recurrence. CONCLUSION: The occurrence of recurrence and especially of early and metastatic recurrence are associated with a worse overall survival. Patients lacking preoperative diabetes, having high preoperative CA19-9 values and lymph node metastases are particularly at risk for (early) recurrence.

RESUMO

INTRODUCTION: Transcatheter aortic valve implantation (TAVI) has become the treatment of choice for the most fragile patients with severe aortic stenosis. The transfemoral route is preferred as the simplest and safest. The aim of our study was to compare the efficacy, tolerance and safety of local vs. locoregional anesthesia in trans-femoral TAVI procedures. MATERIAL AND METHOD: This was a single-center retrospective study. Patients treated with femoral TAVI between February 25 and November 15, 2022 at the University Hospital of Reims were included, and two groups (local and locoregional anesthesia) were compared. RESULTS: TAVI success rate (92.9%), death rate (3.0%) and procedure duration (90.5 ± 13.5 minutes) did not differ between groups (p = 0.18, 0.15 and 0.55 respectively). For intra- and post-procedural treatments, the use of sedation, analgesics and benzodiazepines did not differ between groups. The cumulative dose of Remifentanil used per-procedure was lower in the local anesthesia group than in the locoregional anesthesia group (148.6 ± 71.9 mcg vs. 208.9 ± 110.0 mcg; p = 0.025). CONCLUSIONS: In this non-randomized retrospective study, local and locoregional anesthesia had comparable safety and efficacy in transfemoral TAVI procedures. In a constrained context and with a view to simplification, these results encourage transfemoral TAVIs to be performed under local anaesthesia, and to consider a "PCI-like" approach, without the presence of an anaesthetist, for selected patients without respiratory, musculoskeletal or agitation disorders, or vascular approach difficulties.

RESUMO

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.

RESUMO

BACKGROUND: Hyperthermia treatment planning can be supportive to ensure treatment quality, provided reliable prediction of the heating characteristics (i.e., focus size and effects of phase-amplitude and frequency steering) of the device concerned is possible. This study validates the predictions made by the treatment planning system Plan2Heat for various clinically used phased-array systems. METHODS: The evaluated heating systems were AMC-2, AMC-4/ALBA-4D (Med-Logix srl, Rome, Italy), BSD Sigma-30, and Sigma-60 (Pyrexar Medical, Salt Lake City, UT, USA). Plan2Heat was used for specific absorption rate (SAR) simulations in phantoms representing measurement set-ups reported in the literature. SAR profiles from published measurement data based on E­field or temperature rise were used to compare the device-specific heating characteristics predicted by Plan2Heat. RESULTS: Plan2Heat is able to predict the correct location and size of the SAR focus, as determined by phase-amplitude settings and operating frequency. Measured effects of phase-amplitude steering on focus shifts (i.e., local SAR minima or maxima) were also correctly reflected in treatment planning predictions. Deviations between measurements and simulations were typically < 10-20%, which is within the range of experimental uncertainty for such phased-array measurements. CONCLUSION: Plan2Heat is capable of adequately predicting the heating characteristics of the AMC­2, AMC-4/ALBA-4D, BSD Sigma-30, and Sigma-60 phased-array systems routinely used in clinical hyperthermia.

RESUMO

OBJECTIVE: To present the real-world status and explore the predictors of the efficacy and prognosis of first-line treatment for unresectable hepatocellular carcinoma (uHCC). METHODS: Real-world data of uHCC patients who underwent first-line treatment at 4 hospitals in Northern Anhui, China, from July 2019 to December 2022 were retrospectively collected. The clinicopathological features, haematological indicators, including superoxide dismutase (SOD) and vascular endothelial growth factor-A (VEGF-A), efficacy and safety data were analysed. RESULTS: A total of 153 patients were enrolled and most of them treated with targeted therapy combined with immunotherapy (TI). Compared to patients treated with TI, patients who were administrated with TI plus locoregional therapy (TIL) showed longer median progression-free survival (mPFS) and median overall survival (mOS) times (both p < 0.05), with manageable safety profiles. Moreover, compared to patients with low baseline serum levels of SOD, patients with high baseline serum SOD levels had a better treatment efficacy and had longer mPFS and mOS times (all p < 0.05). Subgroup analyses indicated that patients with low SOD levels had longer mPFS times when receiving TIL than when receiving TI (p = 0.005), but, among patients with high SOD levels, their prognoses were not substantially different between TIL and TI (p > 0.05). Additionally, patients in the low-VEGF-A group had a longer mOS time than patients in the high-VEGF-A group (p = 0.004). In comparison with TI, TIL can improve the survival time among patients with high VEGF-A levels but not among patients with low VEGF-A levels. CONCLUSIONS: TI was the most commonly first-line systemic therapy for uHCC patients, with better efficacy and outcomes when combined with locoregional therapy in a certain population. Baseline serum SOD and VEGF-A were found to be potential predictive biomarkers for decision-making, treatment response, and outcome in patients with uHCC in the primary care setting.


TI was the most commonly used first-line systemic therapy regimen for uHCC patients in Northern Anhui, China.TIL might conferred better therapeutic efficacy and outcome than TI in specific uHCC populations.The baseline serum SOD level was found to be positively correlated with first-line treatment efficacy and patients' prognosis in uHCC, and low-SOD patients with a dismal prognosis was identified to have potential to benefit from TIL.High baseline serum VEGF-A levels were associated with poor efficacy and short OS times in uHCC patients. For patients with a high baseline VEGF-A, TIL is recommended as the first-line treatment.

RESUMO

PURPOSE: Ablative therapies for primary and secondary liver malignancies are increasingly adopted in current guidelines. Nevertheless, surgical resection remains the gold standard in most curative therapy settings. Extensive studies on mortality and morbidity after ablative treatment of the liver are missing. We investigated complications and mortality after ablative treatment in a large, unselected study cohort. MATERIALS AND METHODS: Standardized patient and treatment data in 4374 percutaneous and angiographic ablative procedures of the liver from the DRG-based hospital reimbursement system (diagnosis-related groups) of an academic hospital in Germany were retrospectively evaluated. We analyzed descriptive patient data, length of stay (LOS), pre-existing medical conditions, previous gastrointestinal surgeries, severe complications, and occurrence of death. RESULTS: Treatment of secondary liver malignancies constituted over two-thirds of all procedures (71%, n = 3053). The mean LOS was 4.1 ± 3.5 days. Severe complications were documented in 1.4% and in-house death in 0.2% of cases, significantly more often after treatment with chemoembolization of primary liver malignancies (p = 0.003; p = 0.0001). Previous partial liver resection, partial bowel resection, and chronic renal failure were independent risk factors for the occurrence of severe complications. CONCLUSION: Severe complications and in-hospital death are rare in the treatment of primary and secondary liver malignancies with percutaneous and angiographic procedures. They are a viable alternative or addition to a surgical approach in treating liver lesions.

RESUMO

BACKGROUND: The combination of targeted therapy and immunotherapy has improved the clinical outcomes of unresectable hepatocellular Carcinoma (HCC). However, the overall prognosis remains suboptimal. This study aims to evaluate the efficacy and safety of a novel combination of radiofrequency ablation (RFA) with lenvatinib plus sintilimab in unresectable HCC. METHODS: In this retrospective study, patients diagnosed with unresectable HCC were included and divided into two cohorts: RFA combined with lenvatinib plus sintilimab (R-L-S group) and lenvatinib plus sintilimab (L-S group). The primary efficacy endpoints were objective response rate (ORR) and progression free survival (PFS). Adverse events were analyzed to assess the safety profiles. RESULTS: The median follow-up periods for the entire cohort were 14.0 months. The R-L-S group (n = 60) had a significantly higher ORR than those with L-S alone (n = 62) (40.0% vs. 20.9%; p = 0.022). Moreover, patients in the R-L-S group had improved median PFS (12 vs. 8 months; p = 0.013) and median overall survival (24 vs. 18 months; p = 0.037), as compared with lenvatinib and sintilimab alone. No significant difference in treatment related adverse event (TRAE) of any grade between the two groups. The most common TRAEs of grade ≥ 3 were fatigue 10.0% (6/60) and hand-foot skin reaction 10.0% (6/60) in the R-L-S group and hand-foot skin reaction 11.3% (7/62) in the L-S group. CONCLUSION: In unresectable HCC patients, the incorporation of RFA to lenvatinib plus sintilimab demonstrated improved efficacy without compromising safety compared with lenvatinib plus sintilimab alone.

RESUMO

OBJECTIVE: This retrospective study aimed to compare rates of perioperative mortality and morbidity, especially pulmonary complication, between endovascular aneurysm repair (EVAR) performed under general anesthesia (GA) and under fascia iliaca block (FIB). METHODS: Patients diagnosed with infrarenal abdominal aortic aneurysm (AAA) who were treated with EVAR were included. Retrospective review of electronic medical records was performed. Patient characteristics, operative details, and postoperative results including mortality and morbidity within 30 days were collected. Statistical analysis to compare postoperative outcomes between EVAR under FIB and EVAR under GA was performed. A univariate analysis was conducted to identify factors associated with increased 30-day mortality. RESULTS: This study included 119 patients, 75 in the FIB group and 44 in the GA group. Most patients were male, with 62 (82.5%) in the FIB group and 31 (70.2%) in the GA group, and most patients were hypertensive, with 57 (76%) in the FIB group and 36 (81.8%) in the GA group. Smoking and coronary artery disease (CAD) was more prevalent in the FIB group, p < .05. Thirty-day mortality was not significantly different between the FIB group and the GA group (1 (1.3%) vs 2 (4.5%), p = .554). Pulmonary complication was lower in the FIB group than in the GA group (1.3% vs 11.4%, p = .026). ICU stay was shorter in the FIB group than in the GA group (0.2 vs 4.5 days, p = .012). Univariate analysis showed that chronic obstructive pulmonary disease (COPD) was associated with higher 30-day mortality. CONCLUSIONS: Endovascular aneurysm repair under FIB was feasible. Compared to GA, this approach resulted in lower postoperative pulmonary complications and shorter ICU stay.

RESUMO

Background: Daily image-guided radiotherapy (IGRT) and deep inspiration breath hold (DIBH) technique are recommended for locoregional RT of breast cancer. The optimal workflow for a combination of surface-guided RT (SGRT) with DIBH technique is of current clinical interest. Materials and methods: The setup accuracy at three hospitals was evaluated using different SGRT workflows. A total of 150 patients (2269 image pairs) were analyzed in three groups: patient setup with the AlignRT® SGRT system in Tampere (Site 1, n = 50), the Catalyst™ SGRT system in Turku (Site 2, n = 50) and the Catalyst™ SGRT system in Jönköping (Site 3, n = 50). Each site used their routine workflow with SGRT-based setup and IGRT positioning. Residual errors of the bony chest wall, thoracic vertebra (Th 1) and humeral head were evaluated using IGRT images. Results: Systematic residual errors in the cranio-caudal (CC) direction and in pitch were generally larger at Site 2 than those at Sites 1 and 3 (p = 0.01-0.7). With daily IGRT, only a small difference (p = 0.01-0.9) was observed in residual random errors of bony structures in other directions between sites. Conclusion: The introduction of SGRT and the use of daily IGRT lead to small residual errors when combining the best workflow practices from different hospitals. Our multicenter evaluation led to improved workflow by tightening the SGRT tolerances on Site 2 and fixation modification. Because of mainly small random errors, systematic posture errors in the images need to be corrected after posture correction with new setup surfaces. We recommend tight SGRT tolerances, good fixation and correction of systematic errors.

RESUMO

OBJECTIVE: Phase 1: to determine the feasibility of desensitizing ventral branches of spinal nerves within the rectus sheath using an ultrasound-guided rectus sheath block (USRSB). Phase 2: to determine the effect of preoperative USRSB on intraoperative responses to surgical stimulation and postoperative pain. STUDY DESIGN: Cadaveric study and prospective, randomized, blinded, parallel-arm clinical trial. ANIMALS: A group of five cat cadavers and 37 shelter-owned cats undergoing ovariohysterectomy. METHODS: Phase 1: anatomical dissection was performed on one uninjected cadaver. Abdominal walls were dissected in four cadavers (eight hemiabdomens) following bilateral USRSB using 1:1 new methylene blue and 0.5% bupivacaine (0.8 mL kg-1 total). Phase 2: preoperative bilateral USRSB was performed with 0.8 mL kg-1 of 0.25% bupivacaine (RSB) or equivalent volume of 0.9% saline (CONTROL). Intraoperative systolic arterial blood pressure (SAP), heart rate (HR), respiratory rate (fR) and vaporizer setting (vap%) were recorded before skin incision, during celiotomy and abdominal wall closure. In recovery, cats were administered robenacoxib (2 mg kg-1; CONTROL) or 0.9% saline (0.1 mL kg-1; RSB) subcutaneously. Postoperative pain was evaluated for 6 hours using the Glasgow Composite Measure Pain Scale. RESULTS: Phase 1: spinal nerves T9-L3 were identified within the rectus sheath, and stained in 0%, 40%, 63%, 75%, 100%, 88%, 50% and 13% of hemiabdomens, respectively. Phase 2: 37 cats were included (RSB, n = 17; CONTROL, n = 20). Intraoperatively, SAP, HR and fR were not significantly different between groups. Vap% was significantly lower in RSB during celiotomy (p = 0.036) and closure (p = 0.044). Postoperatively, RSB cats were 5.3 times (95% CI 1.8-8.3) more likely to require rescue analgesia than CONTROL cats. CONCLUSIONS AND CLINICAL RELEVANCE: During surgery, USRSB with bupivacaine offered minor benefits and provided markedly less postoperative analgesia than robenacoxib, indicating that relying on USRSB provides insufficient postoperative analgesia for ovariohysterectomy in cats.

RESUMO

BACKGROUND: Ductal carcinoma in situ (DCIS) is the most common form of preinvasive breast cancer, with 5-10% of cases progressing into invasive disease. Herein, we investigated the association between HER2-low and clinico-pathological characteristics in DCIS and subsequent ipsilateral loco-regional relapse (LRR). MATERIALS AND METHODS: We accessed our prospectively maintained institutional database. HER2 status was determined by immunohistochemistry and classified as null (score 0), over-expressed (3+), and low (1+ or 2+); in situ hybridization was not considered since it is not used for routine DCIS diagnostics. RESULTS: Among 375 patients with DCIS, median age was 54 (27-88) years, with a primary tumor size < 2.5 cm in 63%, grade III in 33%, and positive hormone receptor status (HR) in 81% of cases; 71% underwent breast-conserving surgery, 34% received adjuvant endocrine and 39% radiotherapy. A total of 197 (52%) had tumors with low HER2 expression, which resulted significantly associated with grade I/II (P < .001), Ki67< 20% (P < .001), and HR-positive status (P < .001). HER2-low distribution varied from 19.61% and 50% in ER negative and ER-low (<10%) to 60% and 69% in ER high (50%-95%) and very high tumors (> 95%) (P < .001). After a median 39-month follow-up (IQR 16-65), cumulative incidences of LRR was 0.054. Among 17 patients with paired primary tumor and LRR, 5 had discordant HER2 status, with an even distribution of increased and decreased HER2 expression. CONCLUSIONS: Low HER2 expression in DCIS is associated with features of reduced aggressiveness. Importantly, changes in HER2 expression may occur prompting retesting in recurrent cases, in line with observations in invasive breast cancer.

RESUMO

Immune checkpoint inhibitors (ICIs) have achieved remarkable success in clinical research and practice. Notably, liver metastasis is not sensitive to ICIs. Liver locoregional therapies can cause irreversible damage to tumor cells and release tumor antigens, thereby providing a rationale for immunotherapy treatments in liver metastasis. The combination therapy of ICIs with locoregional therapies is a promising option for patients with liver metastasis. Preclinical studies have demonstrated that combining ICIs with locoregional therapies produces a significantly synergistic anti-tumor effect. However, the current evidence for the efficacy of ICIs combined with locoregional therapies remains insufficient. Therefore, we review the literature on the mechanisms of locoregional therapies in treating liver metastasis and the clinical research progress of their combination with ICIs.

RESUMO

Laparoscopic ovariectomy is generally performed with equids in the standing position, with the animals heavily sedated and restrained in stocks. This procedure may be quite painful, and it is essential first to manage intraoperative pain to complete the surgery, respecting the animal's welfare and, at the same time, ensuring the safety of the operators. Laparoscopy requires multiple small incisions to introduce the instruments, with one to two incisions enlarged sufficiently to remove the ovary. The surgical procedure must be associated with effective pain control, usually obtained with loco-regional anaesthesia, mesovarian injection, mesovaric or ovarian topical anaesthesia, and epidural anaesthesia. This systematic review aims to discuss articles published from 2003 to 2023 on treating loco-regional anaesthesia in standing laparoscopic ovariectomy in association with an evaluation of pain. The literature review was undertaken according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines on three databases (NCBI-PubMed, Web of Science, and SciVerse Scopus). Despite the collected papers numbering 36, we identified only five eligible papers, demonstrating that few studies are performed in order to evaluate the quality of analgesia with loco-regional anaesthesia in standing laparoscopic ovariectomy in equids. The authors of this systematic review agree that the association of injectable and epidural anaesthesia is the best solution to manage intraoperative pain in standing laparoscopic ovariectomy in equids.

RESUMO

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.

RESUMO

INTRODUCTION: Adrenocortical carcinoma (ACC) is a rare and aggressive endocrine malignancy with a high recurrence rate. Approximately half of the patients are asymptomatic, while others experience symptoms due to the tumor's size or hormone secretion. Ro resection if possible is the best option for treatment of primary as well as locoregional recurrent ACC. CASE PRESENTATION: A 20-year-old female who previously underwent open left adrenalectomy for Stage III ACC presented with complaints of heaviness and vague discomfort in the left upper abdomen. Current hormonal assays were normal. Imaging revealed a lesion in the spleen suggestive of recurrence. She underwent elective surgery involving en bloc resection of the spleen, diaphragm, and associated structures. Postoperative recovery was uneventful, histopathology confirmed recurrence and subsequent PET-CT showed no recurrence. She is currently on mitotane and remains symptom-free with no signs of recurrence after initial surgery. CLINICAL DISCUSSION: Complete resection (Ro) if possible, for recurrent and metastatic disease has been linked to long-term survival and offers significant palliative benefits, particularly in cases involving symptomatic steroid production. CONCLUSION: ACC has a high frequency of local recurrence therefore management of recurrence should be considered from the initial diagnosis. Ro resection of recurrence is the best potential treatment. Follow-up protocols and improving integration between surgical, oncological, and supportive care departments are crucial for overcoming healthcare challenges in Nepal.

RESUMO

BACKGROUND: Hepatocellular carcinoma (HCC) is an aggressive malignant neoplasm that requires liver transplantation (LT). Despite patients with HCC being prioritized by most organ allocation systems worldwide, they still have to wait for long periods. Locoregional therapies (LRTs) are employed as bridging therapies in patients with HCC awaiting LT. Although largely used in the past, transarterial embolization (TAE) has been replaced by transarterial chemoembolization (TACE). However, the superiority of TACE over TAE has not been consistently shown in the literature. AIM: To compare the outcomes of TACE and TAE in patients with HCC awaiting LT. METHODS: All consecutive patients with HCC awaiting LT between 2011 and 2020 at a single center were included. All patients underwent LRT with either TACE or TAE. Some patients also underwent percutaneous ethanol injection (PEI), concomitantly or in different treatment sessions. The choice of LRT for each HCC nodule was determined by a multidisciplinary consensus. The primary outcome was waitlist dropout due to tumor progression, and the secondary outcome was the occurrence of adverse events. In the subset of patients who underwent LT, complete pathological response and post-transplant recurrence-free survival were also assessed. RESULTS: Twelve (18.5%) patients in the TACE group (only TACE and TACE + PEI; n = 65) and 3 (7.9%) patients in the TAE group (only TAE and TAE + PEI; n = 38) dropped out of the waitlist due to tumor progression (P log-rank test = 0.29). Adverse events occurred in 8 (12.3%) and 2 (5.3%) patients in the TACE and TAE groups, respectively (P = 0.316). Forty-eight (73.8%) of the 65 patients in the TACE group and 29 (76.3%) of the 38 patients in the TAE group underwent LT (P = 0.818). Among these patients, complete pathological response was detected in 7 (14.6%) and 9 (31%) patients in the TACE and TAE groups, respectively (P = 0.145). Post-LT, HCC recurred in 9 (18.8%) and 4 (13.8%) patients in the TACE and TAE groups, respectively (P = 0.756). Posttransplant recurrence-free survival was similar between the groups (P log-rank test = 0.71). CONCLUSION: Dropout rates and posttransplant recurrence-free survival of TAE were similar to those of TACE in patients with HCC. Our study reinforces the hypothesis that TACE is not superior to TAE as a bridging therapy to LT in patients with HCC.

RESUMO

Objectives: This study was designed to prospectively evaluate the feasibility of an opioid-free anesthesia protocol and describe the quality of recovery and management of postoperative analgesia in dogs after a tibial plateau leveling osteotomy (TPLO). Methods: In total, 20 dogs presented for TPLO were included. After premedication with intravenous (IV) medetomidine (0.005-0.007 mg/kg) and midazolam (0.2 mg/kg), the dogs were anesthetized using ketamine (2 mg/kg) and propofol and maintained with isoflurane and ketamine CRI (0.6 mg/kg/h). Sciatic and femoral nerve blocks were performed with bupivacaine 0.5% (0.087 +/- 0.01 and 0.09 +/- 0.02 mL/kg, respectively). Meloxicam (0.2 mg/kg IV) was administered intraoperatively, after osteotomy. Fentanyl (0.002 mg/kg IV) was administered intraoperatively, as rescue analgesia in the case of sustained increase in cardiorespiratory variables. Two pain scores (French 4A-VET and Glasgow short form) were performed at conscious sternal recumbency and 2, 4, 6, 8, 12, and 20 h after extubation and compared to baseline using a Friedman test followed by a Nemenyi post-hoc test. The time taken for the first food intake and urination was reported. Results: Intraoperative opioid-free anesthesia was feasible in 11 dogs, whereas 9 dogs received fentanyl once during arthrotomy. No opioid postoperative rescue analgesia was required. Food intake occurred within 6 h, and all dogs were discharged after 24 h without any complication. Conclusion: Total opioid-free postoperative analgesia was achieved in all dogs, with adequate recoveries. Although opioid-free anesthesia was feasible in 55% of the population, a single dose of fentanyl was necessary in 45% of the dogs during arthrotomy.
