RESUMO
The aim of this study was to evaluate outcomes of transarterial radioembolization (TARE) for hepatocellular carcinoma (HCC) in patients previously treated with transarterial embolization (TAE). In this retrospective study, all HCC patients who received TARE from 1/2012 to 12/2022 for treatment of residual or recurrent disease after TAE were identified. Overall survival (OS) was estimated using the Kaplan-Meier method. Univariate Cox regression was performed to determine significant predictors of OS after TARE. Twenty-one patients (median age 73.4 years, 18 male, 3 female) were included. Median dose to the perfused liver volume was 121 Gy (112-444, range), and 18/21 (85.7%) patients received 112-140 Gy. Median OS from time of HCC diagnosis was 32.9 months (19.4-61.4, 95% CI). Median OS after first TAE was 29.3 months (15.3-58.9, 95% CI). Median OS after first TARE was 10.6 months (6.8-27.0, 95% CI). ECOG performance status of 0 (p = 0.038), index tumor diameter < 4 cm (p = 0.022), and hepatic tumor burden < 25% (p = 0.018) were significant predictors of longer OS after TARE. TARE may provide a survival benefit for appropriately selected patients with HCC who have been previously treated with TAE.

Image-guided intra-arterial locoregional therapies (LRTs) such as transarterial embolization, transarterial chemoembolization, and transarterial radioembolization exhibit effects on the immune system. Understanding the humoral (cytokine, chemokine, and growth factor) and cellular (T cell, neutrophil, dendritic cell, and macrophage) mechanisms underlying the immune effects of LRT is crucial to designing rational and effective combinations of immunotherapy and interventional radiology procedures. This article aims to review the immune effects of intra-arterial LRTs and provide insight into strategies to combine LRTs with systemic immunotherapy.

Cervical cancer (CC), caused by human papillomavirus (HPV), is a leading cause of female malignancies worldwide. Therefore, understanding the underlying mechanisms of CC development and identifying novel therapeutic targets are significantly important. Cisplatin resistance is a significant challenge in the management of CC. Recent studies highlighted the critical role of long non-coding RNAs (lncRNAs) in modulation of cisplatin resistance. This comprehensive review aims to collect the current understanding roles of lncRNAs and their involvement in cisplatin resistance in CC by highlighting key processes of cancer progression, including apoptosis, proliferation, angiogenesis and epithelial-to-mesenchymal transition (EMT). We discussed the role of lncRNA in CC resistance to cisplatin through molecular pathways and examined gene expression changes. We also discussed treatment strategies and factors that reduce CC resistance to cisplatin by targeting them.
RESUMO
Hepatocellular cancer (HCC) is the most common primary liver cancer and the third leading cause of cancer-related death. Locoregional therapies, including transarterial embolization (TAE: bland embolization), chemoembolization (TACE), and radioembolization, have demonstrated survival benefits when treating patients with unresectable HCC. TAE and TACE occlude the tumor's arterial supply, causing hypoxia and nutritional deprivation and ultimately resulting in tumor necrosis. Embolization blocks the aerobic metabolic pathway. However, tumors, including HCC, use the "Warburg effect" and survive hypoxia from embolization. An adaptation to hypoxia through the Warburg effect, which was first described in 1956, is when the cancer cells switch to glycolysis even in the presence of oxygen. Hence, this is also known as aerobic glycolysis. In this article, the adaptation mechanisms of HCC, including glycolysis, are discussed, and anti-glycolytic treatments, including systemic and locoregional options that have been previously reported or have the potential to be utilized in the treatment of HCC, are reviewed.

PURPOSE: Transarterial radioembolization (TARE) is a liver-directed treatment for unresectable intrahepatic cholangiocarcinoma (ICC). The aim of this study is to evaluate factors affecting outcomes of TARE in heavily pretreated ICC patients. METHODS: We evaluated pretreated ICC patients who received TARE from January 2013 to December 2021. Prior treatments included systemic therapy, hepatic resection, and liver-directed therapies, including hepatic arterial infusion chemotherapy, external beam radiation, transarterial embolization, and thermal ablation. Patients were classified based on history of hepatic resection and genomic status based on next-generation sequencing (NGS). The primary endpoint was overall survival (OS) after TARE. RESULTS: Fourteen patients with median age 66.1 years (range, 52.4-87.5), 11 females and 3 males, were included. Prior therapies included systemic in 13/14 patients (93%), liver resection in 6/14 (43%), and liver-directed therapy in 6/14 (43%). Median OS was 11.9 months (range, 2.8-81.0). Resected patients had significantly longer median OS compared to unresected patients (16.6 versus 7.9 months; p = 0.038). Prior liver-directed therapy (p = 0.043), largest tumor diameter > 4 cm (p = 0.014), and > 2 hepatic segments involvement (p = 0.001) were associated with worse OS. Nine patients underwent NGS; 3/9 (33.3%) and had a high-risk gene signature (HRGS), defined as alterations in TP53, KRAS, or CDKN2A. Patients with a HRGS had worse median OS (10.0 versus 17.8 months; p = 0.024). CONCLUSIONS: TARE may be used as salvage therapy in heavily treated ICC patients. Presence of a HRGS may predict worse OS after TARE. Further investigation with more patients is recommended to validate these results.

INTRODUCTION: Sepsis is defined as life-threatening organ dysfunction in result of the host's dysregulated response to infection and septic shock. Sepsis-associated kidney injury is usually defined as concurrent presence of acute kidney injury (AKI) and sepsis without other significant causative factors. METHOD: The current retrospective study was conducted to elucidate beneficial and side effects of CytoSorb®. A total of 17 patients were primarily treated with continuous renal replacement therapy in combination with CytoSorb. The demand for norepinephrine, mean arterial pressure, lactate, and procalcitonin (PCT) levels, as well as ICU length of stay, was measured. RESULT: The blood lactate levels decreased by 32.30% when comparing mean levels before and after treatment. All patients who survived (n = 14) had reduction in vasopressor demand to 68.96% of their initial dose before the start of treatment. Hospital survival was greater in patients who initially had higher vasopressor demand compared to their nonsurviving counterparts, but in whom vasopressor dosages were reduced significantly during their treatments. Mortality as predicted by APACHE II score in the overall patient population was 79.9%, whereas, the observed ICU mortality was 31%. The baseline PCT levels on patients received 1, 2, and 3 CytoSorbs were 27.08 ± 5.81 ng/mL, 13.28 ± 2.62 ng/mL, and 21.03 ± 6.56 ng/mL, respectively. Observed PCT levels at 24 h after the last treatment on patients received 1, 2, and 3 CytoSorb were 31.55 ± 15.70 ng/mL, 5.61 ± 1.77 ng/mL, and 8.11 ± 3.62 ng/mL, respectively. CONCLUSION: In conclusion, it seems that applying the CytoSorb in combination with CRRT in ICU septic patients with AKI, is related to a significant decrease in mortality, if the integrity and continuity of the treatment be kept, as much as possible. This study presented an effectively positive outcome with cytokine adsorber treatment as an adjuvant along with standard treatment in a high-risk mortality case of septic shock with organ failure.

BACKGROUND: Endometriosis is an important cause of chronic pain and infertility. Surgery is considered the gold standard for diagnosis and treatment. In this study, we aim to describe the clinical outcomes of women who undergo laparoscopic surgery for endometriosis. MATERIALS AND METHODS: In this cohort study, a total of 174 women who referred to Farmaniyeh Hospital, Tehran, Iran from August 2015 to December 2017 with surgical diagnoses of endometriosis stages III and IV enrolled. The participants' demographic, gynaecological, and clinical characteristics were recorded and they were asked to use a numeric rating scale (NRS) to record their severity of pain before and three months after surgery. Blood samples were also taken from the patients before and three months after surgery for measurement of serum levels of anti-Müllerian hormone (AMH) and cancer antigen 125 (CA-125). Data were analysed using SPSS version 21. RESULTS: The patients had a mean age of 34.86 ± 6.47 years, 60.9% were married, and 49.4% were housewives. The primary indication for surgery was pain (68.4%), followed by both pain and infertility in the remainder of patients. Types of endometriotic lesions included endometrioma (19%), deep infiltrating endometriosis (DIE, 3.4%), and both endometrioma and DIE (77.6%). There was a reduction in pain from 6.79 ± 2.19 before surgery to 1.48 ± 1.68 after surgery; serum AMH levels reduced from 2.80 ± 1.86 ng/mL to 1.76 ± 1.40 ng/mL and CA125 reduced from 257.06 ± 220.25 U/mL to 23.27 ± 23.25 U/mL (all P<0.001). Of the 21.2% who experienced recurrence, 13.5% underwent additional surgery. The total additional surgery rate was 2.8%. Of the 55 patients with infertility, 78.1% became pregnant after surgery, 54.5% of which was spontaneous. CONCLUSION: Surgical treatment of endometriosis had a favourable effect on the patients' pain and inflammation and resolved the patients' infertility with a minimal need for additional surgery.
