Acrokeratosis paraneoplastica (Basex syndrome) is a rare paraneoplastic condition hallmarked by psoriasiform lesion development on acral surfaces, most often related to an underlying squamous cell carcinoma. Patients may also present with nail plate changes. Successful management of this condition can be accomplished by treating the underlying malignancy.

BACKGROUND: The risk of developing cutaneous T cell lymphoma (CTCL) in patients using psoriasis biologics has not been well characterized. The goals of this review were to investigate the incidence of CTCL in patients with psoriasis receiving biologic therapy in clinical trials and psoriasis registries, and to review cases of CTCL and biologic use reported in scientific publications. METHODS: The US National Library of Medicine clinical trials database (clinicaltrials.gov) was queried to identify phase 3 and 4 clinical trials of the 12 biologic agents currently FDA approved for psoriatic disease. The incidence of CTCL in these trials was examined and summarized. To examine the incidence of CTCL in psoriasis registries, a Medline search was conducted. Finally, we performed a systematic review of CTCL cases reported in the literature. RESULTS: Only two cases of CTCL were reported in 35,801 subjects with psoriasis receiving a biologic agent in the active arm of 108 psoriasis phase 3 clinical trials. One of these CTCL cases was determined by the investigator to be CTCL misdiagnosed as psoriasis prior to randomization. No cases of CTCL were reported in 5440 subjects with psoriasis in 34 phase 4 clinical trials. Only one case of CTCL was identified in 34,111 registry subjects. In the literature, tumor necrosis factor (TNF) inhibitors had the highest number of reported cases of CTCL (34 cases), followed by interleukin (IL)-17 inhibitors (7 cases), and IL-12/23 inhibitors (6 cases). No cases of CTCL were found to be reported with IL-23 inhibitors. CONCLUSION: Our findings indicate that the development of CTCL is rare in the setting of psoriasis biologic use. Of the limited number of cases of CTCL found, most were in the setting of TNF inhibitor use and no cases of CTCL were reported in the setting of IL-23 inhibitor use.

ABSTRACT Objectives Methods Results Conclusions To transform the standardized descriptions of the ultrasound characteristics of endometrial and intrauterine lesions devised by the International Endometrial Tumor Analysis (IETA) group into a practical scoring method and to investigate whether application of this method enhances the diagnostic accuracy of ultrasound radiologists with different levels of experience in detecting malignancy compared with subjective assessment.This was a retrospective study of 855 patients with endometrial and/or intrauterine lesions, who were divided into a training (n = 600) and a validation (n = 255) set. Ultrasound radiologists with varying levels of experience (expert, intermediate and junior) evaluated all lesions by subjective assessment and according to IETA rules. Using IETA rules, the experts identified signs of malignancy in the training set, assigned scores for each indicator and validated the scoring method in the validation set. The intermediate‐level and junior ultrasound radiologists reassessed the malignancy of the lesions using the IETA scoring method and compared their classifications with those made previously by subjective assessment. Postsurgical pathological evaluation was used as the reference standard.Using subjective assessment, the experts demonstrated the highest level of diagnostic accuracy, with a sensitivity of 85.0%, specificity of 94.3% and an area under the receiver‐operating‐characteristics curve (AUC) of 0.897. Applying the IETA scoring method (comprising eight ultrasound characteristics that contributed to the total score) with a threshold of > 25 points for the diagnosis of malignancy achieved a sensitivity of 84.7%, specificity of 94.7% and AUC of 0.9533 in the training set, with similar performance in the validation set, when performed by experts. Using the IETA scoring method, both junior and intermediate ultrasound radiologists showed improvement in sensitivity (from 55.5% to 74.8% and from 70.2% to 77.1%, respectively), specificity (from 88.4% to 91.5% and from 87.4% to 92.2%, respectively) and AUC (from 0.704 to 0.827 and from 0.793 to 0.841, respectively) for diagnosing malignant lesions.The IETA scoring method exhibits high diagnostic efficacy for malignant endometrial and intrauterine lesions. This method compensates for the lack of experience among junior and intermediate‐level ultrasound radiologists, enhancing their diagnostic skill to a level nearing that of experienced senior ultrasound radiologists. Further research is essential to validate the practicality of implementing this method and to confirm its clinical value. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

Objective: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with a variable clinical manifestation, potentially leading to death. Importantly, patients with SLE have an increased risk of neoplastic disorders. Thus, this study aimed to comprehensively evaluate the clinical and laboratory characteristics of patients with SLE and with or without malignancy. Methods: We conducted a retrospective analysis of medical records of 932 adult Caucasian patients with SLE treated at the University Hospital in Kraków, Poland, from 2012 to 2022. We collected demographic, clinical, and laboratory characteristics, but also treatment modalities with disease outcomes. Results: Among 932 patients with SLE, malignancy was documented in 92 (9.87%), with 7 (7.61%) patients experiencing more than one such complication. Non-hematologic malignancies were more prevalent (n = 77, 83.7%) than hematologic malignancies (n = 15, 16.3%). Patients with SLE and malignancy had a higher mean age of SLE onset and a longer mean disease duration than patients without malignancy (p < 0.001 and p = 0.027, respectively). The former group also presented more frequently with weight loss (odds ratio [OR] = 2.62, 95% confidence interval [CI] 1.61–4.23, p < 0.001), fatigue/weakness (OR = 2.10, 95% CI 1.22–3.77, p = 0.005), and fever (OR = 1.68, 95% CI 1.06–2.69, p = 0.024). In the malignancy-associated group, we noticed a higher prevalence of some clinical manifestations, such as pulmonary hypertension (OR = 3.47, 95% CI 1.30–8.42, p = 0.007), lung involvement (OR = 2.64, 95% CI 1.35–4.92, p = 0.003) with pleural effusion (OR = 2.39, 95% CI 1.43–3.94, p < 0.001), and anemia (OR = 2.24, 95% CI 1.29–4.38, p = 0.006). Moreover, the patients with SLE and malignancy more frequently had internal comorbidities, including peripheral arterial obliterans disease (OR = 3.89, 95% CI 1.86–7.75, p < 0.001), myocardial infarction (OR = 3.08, 95% CI 1.41–6.30, p = 0.003), heart failure (OR = 2.94, 95% CI 1.30–6.17, p = 0.005), diabetes mellitus (OR = 2.15, 95% CI 1.14–3.91, p = 0.011), hypothyroidism (OR = 2.08, 95% CI 1.29–3.34, p = 0.002), arterial hypertension (OR = 1.97, 95% CI 1.23–3.23, p = 0.003), and hypercholesterolemia (OR = 1.87, 95% CI 1.18-3.00, p = 0.006). Patients with SLE and malignancy were treated more often with aggressive immunosuppressive therapies, including cyclophosphamide (OR = 2.07, 95% CI 1.30–3.28, p = 0.002), however median cumulative cyclophosphamide dose in malignancy-associated SLE subgroup was 0 g (0–2 g). Interestingly, over a median follow-up period of 14 years (ranges: 8–22 years) a total of 47 patients with SLE died, with 16 cases (5.28%) in the malignancy-associated SLE group and 31 cases (5.73%) in the non-malignancy SLE group (p = 0.76). The most common causes of death were infections (21.28%) and SLE exacerbation (8.51%). Conclusion: The study highlights the relatively frequent presence of malignancies in patients with SLE, a phenomenon that demands oncological vigilance, especially in patients with a severe clinical course and comorbidities, to improve long-term outcomes in these patients.

Dermatomyositis (DM) is associated with interstitial lung disease (ILD) and malignancy. However, the coexistence of ILD and malignancy (DM–ILD–malignancy) is rare, and limited information exists regarding its management. Herein, we report the case of a 70-year-old man who developed DM with rapidly progressive ILD and advanced gastric cancer and provide a literature review of managing DM–ILD–malignancy. The patient presented with typical DM skin rashes and shortness of breath, which worsened within 1 month, without muscular symptoms. Additionally, the patient tested negative for myositis-specific autoantibodies (MSAs). Computed tomography revealed ILD and advanced gastric cancer, which was confirmed on endoscopic examination to be a poorly differentiated adenocarcinoma. Although the patient's ILD progressed rapidly, surgical treatment of the cancer was prioritized. Prednisolone (PSL) 0.5 mg/kg was initiated 3 days before surgery and increased to 1 mg/kg at 7 days postoperative. Remarkable improvement in the skin rash and ILD was observed, and the PSL dose was tapered without immunosuppressants. A literature review revealed that anti-melanoma differentiation-associated gene 5 and anti-aminoacyl transfer RNA synthetase antibodies are the predominant MSAs in DM–ILD–malignancy, and the optimal treatment should be determined based on several factors, including ILD patterns, and malignancy type and stage. In particular, lung cancer may be a risk factor for the acute exacerbation of ILD, and preceding immunosuppression would be useful. Furthermore, prioritizing surgery for gastric cancer is effective because of its paraneoplastic nature. [ABSTRACT FROM AUTHOR]

Purpose: Percutaneous thermal ablation is an effective treatment for primary and metastatic liver tumors and is a recommended local therapy for early-stage hepatocellular carcinoma (HCC). Reported evidence shows an increase in the ablation zone volume over the first 24-h post-liver ablation. This report compares ablation zone volumes immediately at the completion (T = 0) of 26 microwave ablations of liver tumors to 24-h post-procedure (T = 24) volumes. Materials and methods: 20 patients, 13 (65%) males, underwent a total of 26 hepatic microwave ablations (MWA) under ultrasound guidance. Contrast-enhanced CT (CECT) or MRI was performed immediately and another CECT 24 h post operatively. Evaluation of the ablation zone and comparison of the two post-operative scans were done using BioTrace software. The expansion of ablation zones on post-op CECTs was matched point by point per direction. The distance between each 2 points was measured and grouped by distance. The incidence of each specific distance was then converted into a percentage, first for each case separately, then for all cases altogether. Data were tested by a matched paired one-sided t test. Results: The median lesion diameter was 1.5 cm (range 0.5–3.3) with 16 (62%) HCC cases and 9 hepatic metastases (4 neuroendocrine carcinoma, 4 colorectal carcinomas, 1 breast carcinoma, 1 pancreatic cancer). The data show a consistent volume expansion greater than 30% (p = 7.7e−5) 24-h post-ablation, where the median expansion is 57%. Distances between T = 0 and T = 24 equal to 3–7 mm occur in over 35% of the cases. Conclusion: The ablation zone expansion at 24-h post-op was not uniform. The final ablation zone is difficult to predict at the time of the procedure. The awareness of the ablation zone expansion is important when treating near-critical structures, managing the heat sink effect, and preserving liver parenchyma. [ABSTRACT FROM AUTHOR]

Approximately 5–15% of all dermatologic malignancies manifest in the upper and lower eyelids. The primary types include basal cell carcinoma, squamous cell carcinoma, and sebaceous cell carcinoma, with Merkel cell carcinoma and melanoma following closely behind. Basal cell carcinoma predominantly affects the lower eyelid, yet various other carcinomas, melanomas, metastases, and neoplasms of diverse origins can arise on both upper and lower eyelids. Risk factors such as advanced age, smoking, and notably, exposure to UV light significantly contribute to the development of these eyelid lesions. Despite the increasing incidence, research on dermatologic eyelid malignancies remains limited. However, such study is imperative given that many systemic oncologic malignancies initially present as metastatic eyelid lesions. This paper provides an in-depth exploration of eyelid anatomy, clinical presentation, diagnosis, and treatment management. Key Points: Eyelid metastases represent less than one percent of all eyelid cancers, yet they often serve as the initial indication of an underlying systemic malignancy. Early detection and treatment is crucial in improving prognosis and quality of life for patients. Treatment options encompass a range of modalities, with Mohs surgery as the gold standard for the removal of ocular tumors. Additional treatment options include local excision as well as non-surgical interventions such as radiotherapy, cryotherapy, immunotherapy, and topical medications. [ABSTRACT FROM AUTHOR]

Background: Juvenile dermatomyositis (JDM) is a rare autoimmune myopathy whose main clinical manifestations include a characteristic rash, symmetrical proximal muscle weakness, and elevated muscle enzymes. While approximately one-third of adult patients with dermatomyositis (DM) develop malignancies, typically within a year of diagnosis, this phenomenon is not commonly observed in patients with JDM. In this study, we present a rare case of both JDM and Hodgkin's lymphoma (HL) diagnosed in an adolescent female patient. Case description: A 14-year-old girl with proximal muscle weakness and myalgia for 8 weeks was admitted to the hospital and ultimately received a diagnosis of DM. A thorough physical examination revealed enlarged lymph nodes on both sides of the cervical, and a lymph node biopsy was performed to diagnose HL. After she underwent radiotherapy and chemotherapy, her symptoms of both HL and DM were alleviated. Conclusion: The phenomenon of JDM as a paraneoplastic syndrome associated with HL is very rare. Thus, routine cancer screening for DM in adolescents is currently not recommended. The diagnosis of JDM requires a detailed physical examination, and further tumor screening is necessary for patients with unusual physical findings, such as atypical rashes, enlarged lymph nodes, and enlargement of the spleen and/or liver. Even if no malignancy is detected when JDM is diagnosed, long-term follow-up is necessary. [ABSTRACT FROM AUTHOR]

Background: Non-resolving pneumonia poses a significant clinical challenge. It is common to treat non-resolving pneumonia over an extended period of time, without evaluating the cause of failure or eliciting the exact aetiology. Objective: To determine the aetiology and clinical-radiological profile of non-resolving pneumonia. Materials and methods: Analytical, observational study done among 77 consecutive patients with non-resolving pneumonia, who attended a tertiary care centre over 1 year. Clinical details were obtained using prefixed questionnaires. Necessary diagnostic procedures like bronchoscopy and image guided transthoracic sampling along with histopathological and microbiological investigations were done to obtain final diagnosis. Results: The most common aetiology was lung malignancy (44.2%) followed by chronic infections (40.3%) dominated by tuberculosis (14.3%). Adenocarcinoma (32.5%) was the commonest malignancy presenting as non-resolving consolidation. History of smoking (p value 0.001), chest pain (p value 0.001), and haemoptysis (p value 0.006) was associated with a diagnosis of malignancy. Actinomycosis (7%) had a significant association with chest pain (p value 0.032). Transthoracic image-guided tissue sampling had a high diagnostic yield of 84.8% and bronchoscopy of 66.9%. Conclusion: Malignancy needs to be considered promptly once we encounter with non-resolution of consolidation. The clinical pointers like advanced age, smoking history, symptoms more than 8 weeks, symptoms like chest pain, and haemoptysis mandate evaluation for malignancy in non-resolving pneumonia. The labyrinth of diabetes mellitus impedes the timely resolution of infections. [ABSTRACT FROM AUTHOR]

Background: Skin neoplasms, particularly basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), are prevalent forms of skin malignancies. To enhance accurate diagnosis, non‐invasive techniques including high‐frequency ultrasound (HFUS) are crucial. HFUS offers deeper penetration compared to reflectance confocal microscopy (RCM), and optical coherence tomography (OCT), making it valuable for examining skin structures. The aim of this study was to investigate and diagnose localized manifestation of BCC and SCC with HFUS and compare it with pathology results in patients referred to Razi Hospital, Tehran, Iran. Method and materials: This study included patients diagnosed with BCC and SCC, with clinical and pathological confirmation, attending the oncology clinic of Razi Hospital, Tehran, Iran, from 2022 to 2023. Exclusion criteria comprised metastatic and recurrent cases, patients who underwent treatment or surgery, and tumors located in anatomically challenging areas. HFUS with a 20 MHz probe and Doppler ultrasound were employed to examine the skin. Tumors were subsequently excised, fixed in formalin, and sent for pathological assessment. Ultrasound findings were compared with pathology results. Results: The study assessed 40 patients, with half diagnosed with SCC and the other half with BCC. The majority of SCC patients were male (80%), while BCC patients were relatively evenly divided between males (65%) and females (35%). The mean age was 59.15 ± 11.9 years for SCC and 63.4 ± 8.9 years for BCC. Cheeks (20%) and lips (35%) were the most common sampling sites for BCC and SCC, respectively. The correlation coefficients for tumor size and depth between ultrasound and pathology were 0.981 and 0.912, respectively, indicating a high level of agreement between the two methods. Conclusion: In BCC patients, there was complete agreement between sonographic loco‐regional extension and pathology findings. However, some discordance (30%) was observed in SCC cases. The study demonstrated a strong correlation between ultrasound and pathology in accurately detecting the depth and extent of the tumor. However, due to the inclusion of only patients with positive pathology, it is not appropriate to evaluate the diagnostic test values and compare them with pathology results. Therefore, it is highly recommended to carry out additional studies with larger sample sizes to further validate these findings. [ABSTRACT FROM AUTHOR]

Key Clinical Message: Cutaneous leishmaniasis is caused by protozoan parasites of the genus leishmania. Atypical presentation and widespread progression of the lesions may be seen in an immunocompromised patient. We report a case of atypical and widespread cutaneous leishmaniasis in a young woman with breast cancer. [ABSTRACT FROM AUTHOR]

Key Clinical Message: Malignancy may be a possible cause of systemic lupus erythematosus (SLE) flare‐ups, and it is necessary to consider it in the context of treatment resistance. In this case, we present a challenging instance of concomitant nodal marginal zone B‐cell lymphoma (NMZL) and SLE flare‐up in a 41‐year‐old male patient. Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can cause various symptoms and affect multiple organs in the body. It is also associated with the development of malignancies, especially lymphomas. This case report discusses a patient who experienced a flare‐up of SLE along with hypercalcemia, which led to the diagnosis of nodal marginal zone B‐cell lymphoma (NMZL). This is the first case of its kind to be reported. A 41‐year‐old man with a 10‐year history of SLE and antiphospholipid syndrome (APS) was referred to our center due to several symptoms, including fatigue, oral lesions, dyspnea, bilateral wrist pain and inflammation, mild pericardial effusion, organ enlargement, pancytopenia, high erythrocyte sedimentation (ESR) level, high anti‐double stranded DNA (anti‐dsDNA) level, low complement level, resistant hypercalcemia, and high brain natriuretic peptide (pro‐BNP) level. After further testing, it was discovered that the patient had NMZL, which was the ultimate diagnosis. He underwent six cycles of the R‐CHOP chemotherapy regimen, and his clinical and laboratory conditions improved during follow‐ups. The initial case of SLE flare‐up, with concomitant NMZL is being reported as the final diagnosis. In simpler terms, it is possible for lymphoma to manifest as a potential cause of SLE flare‐ups, and clinicians should be mindful that they need to consider malignant conditions when faced with treatment resistance.

AIMS: Individuals with a higher De Ritis ratio (aspartate transaminase/alanine transaminase) and neutrophil-to-lymphocyte ratio (NLR) have an inferior survival in varied malignancies. To our knowledge, the prognostic potential of the De Ritis ratio and NLR to predict the survival in nonmetastatic glioblastoma multiforme (GBM) patients remains unclear. In this study, we aimed to explore the prognostic power of the De Ritis ratio and NLR in patients with nonmetastatic glioblastoma multiforme. METHODS: Data of 262 patients with glioblastoma multiforme have been retrospectively analyzed. Their age, gender, tumor characteristics, AST/ALT ratio, NLR and hemogram values, including age at diagnosis and date of diagnosis were recorded. RESULTS: The median survival time of the study group was 21 months (95% CI: 19-23 months). The first-year and second-year survival rates were 73.0% and 40.5%, respectively. The univariate analysis revealed that the correlation of survival with age, gender, left/right location of tumor, mean platelet volume and De Ritis ratio did not reach the level of significance. The univariate analysis of the prognostic potential of NLR indicated that a 1-unit increase in NLR value translates to a 1.05 times higher risk of death (95% CI: 1.01-1.09). CONCLUSION: The results of this study lead to the observation that NLR value can serve as an effective prognostic marker in predicting the outcomes of patients with glioblastoma multiforme. It can be positioned as an easily accessible and cost-effective biomarker for establishing appropriate therapeutic strategies [ABSTRACT FROM AUTHOR]

Cancer remains a significant challenge in medicine due to its complexity and heterogeneity. Biomarkers have emerged as vital tools for cancer research and clinical practice, facilitating early detection, prognosis assessment, and treatment monitoring. Among these, CD40 ligand (CD40L) has gained attention for its role in immune response modulation. Soluble CD40 ligand (sCD40L) has shown promise as a potential biomarker in cancer diagnosis and progression, reflecting interactions between immune cells and the tumor microenvironment. This review explores the intricate relationship between sCD40L and cancer, highlighting its diagnostic and prognostic potential. It discusses biomarker discovery, emphasizing the need for reliable markers in oncology, and elucidates the roles of CD40L in inflammatory responses and interactions with tumor cells. Additionally, it examines sCD40L as a biomarker, detailing its significance across various cancer types and clinical applications. Moreover, the review focuses on therapeutic interventions targeting CD40L in malignancies, providing insights into cellular and gene therapy approaches and recombinant protein-based strategies. The clinical effectiveness of CD40L-targeted therapy is evaluated, underscoring the need for further research to unlock the full potential of this signaling pathway in cancer management.

Introduction: Malignant brain tumors are malignancies which are known for their low survival rates. Despite advancements in treatments in the last decade, the disparities in malignant brain cancer mortality among the US population remain unclear. Methods: We analyzed death certificate data from the US CDC WONDER from 1999 to 2020 to determine the longitudinal trends of malignant brain tumor mortality. Malignant brain tumor (ICD-10 C71.0–71.9) was listed as the underlying cause of death. Age-adjusted mortality rates (AAMRs) per 100,000 individuals were calculated by standardizing the AAMR to the year 2000 US population. Results: From 1999 to 2020, there were 306,375 deaths due to malignant brain tumors. The AAMR decreased from 5.57 (95% CI, 5.47–5.67) per 100,000 individuals in 1999 to 5.40 (95% CI, 5.31–5.48) per 100,000 individuals in 2020, with an annual percent decrease of −0.05 (95% CI, −0.22, 0.12). Whites had the highest AAMR (6.05 [95% CI, 6.02–6.07] per 100,000 individuals), followed by Hispanics (3.70 [95% CI, 3.64–3.76]) per 100,000 individuals, blacks (3.09 [95% CI, 3.04–3.14] per 100,000 individuals), American Indians (2.82 [95% CI, 2.64–3.00] per 100,000 individuals), and Asians (2.44 [95% CI, 2.38–2.50] per 100,000 individuals). The highest AAMRs were reported in the Midwest region (5.58 [95% CI, 5.54–5.62] per 100,000 individuals) and the rural regions (5.66 [95% CI, 5.61–5.71] per 100,000 individuals). Conclusions: Our study highlights the mortality disparity among different races, geographic regions, and urbanization levels. The findings underscore the importance of addressing the disparities in malignant brain tumors that existed among males, white individuals, and rural populations. [ABSTRACT FROM AUTHOR]

Objectives To compare clinical characteristics, including the frequency of cutaneous, extramuscular manifestations and malignancy, between adults with anti-synthetase syndrome (ASyS) and DM. Methods Using data regarding adults from the MYONET registry, a cohort of DM patients with anti-Mi2/-TIF1γ/-NXP2/-SAE/-MDA5 autoantibodies, and a cohort of ASyS patients with anti-tRNA synthetase autoantibodies (anti-Jo1/-PL7/-PL12/-OJ/-EJ/-Zo/-KS) were identified. Patients with DM sine dermatitis or with discordant dual autoantibody specificities were excluded. Sub-cohorts of patients with ASyS with or without skin involvement were defined based on presence of DM-type rashes (heliotrope rash, Gottron's papules/sign, violaceous rash, shawl sign, V-sign, erythroderma, and/or periorbital rash). Results In total 1054 patients were included (DM, n  = 405; ASyS, n  = 649). In the ASyS cohort, 31% (n  = 203) had DM-type skin involvement (ASyS-DMskin). A higher frequency of extramuscular manifestations, including Mechanic's hands, Raynaud's phenomenon, arthritis, interstitial lung disease and cardiac involvement differentiated ASyS-DMskin from DM (all P  < 0.001), whereas higher frequency of any of four DM-type rashes—heliotrope rash (n  = 248, 61% vs n  = 90, 44%), violaceous rash (n  = 166, 41% vs n  = 57, 9%), V-sign (n  = 124, 31% vs n  = 28, 4%), and shawl sign (n  = 133, 33% vs n  = 18, 3%)—differentiated DM from ASyS-DMskin (all P  < 0.005). Cancer-associated myositis (CAM) was more frequent in DM (n  = 67, 17%) compared with ASyS (n  = 21, 3%) and ASyS-DMskin (n  = 7, 3%) cohorts (both P  < 0.001). Conclusion DM-type rashes are frequent in patients with ASyS; however, distinct clinical manifestations differentiate these patients from classical DM. Skin involvement in ASyS does not necessitate increased malignancy surveillance. These findings will inform future ASyS classification criteria and patient management. [ABSTRACT FROM AUTHOR]

We recently characterized the clinical performance of a multivariate index assay (MIA3G) to assess ovarian cancer risk for adnexal masses at initial presentation. This study evaluated how MIA3G varies when applied longitudinally to monitor risk during clinical follow-up. The study evaluated women presenting with adnexal masses from eleven centers across the US. Patients received an initial blood draw at enrollment and at the standard-of-care follow-up visits. MIA3G was determined for all visits but physicians did not have access to MIA3G scores to determine clinical management. The primary outcome was the relative change value (RCV) of MIA3G over the period of clinical observation. A total of 510 patients of 785 enrolled met study criteria. Of these, 30.8% had a second, 25.4% a third and 22.2% a fourth blood draw following initial collection. The median duration from initial draw was 131 d to second draw, 301.5 d to the third draw and 365.5 d to the fourth draw. MIA3G RCV of >50% was observed in 22–26% patients, whereas 70–75% patients had MIA3G RCV >5%. An empirical baseline RCV of 56% – transformed to 1 in logarithmic scale – was calculated from averaging RCVs of all patients who had no malignancy risk after 210 days. RCV > 1 log was associated with higher incidence of surgical intervention (29.6%) compared to RCV < 1 log (16.9%). Variation in MI3AG does not change the accuracy of the test for excluding malignancy, while marked changes may be associated with a slightly higher likelihood of surgical intervention. In addition to MIA3G score itself, the MIA3G RCV may be important for clinical management. • This study examined a novel application of multivariate index assay for longitudinal monitoring of ovarian cancer risk. • Relative change value of the MIA score post follow-up was associated with a higher incidence of surgical intervention. • The findings indicated the MIA relative change value is a useful clinical tool to monitor cancer risk for adnexal mass.

Objectives: Splenic lesions might exhibit overlapping imaging features, varying from benign entities like cysts and hemangiomas to malignancies such as lymphoma and angiosarcoma. This meta-analysis aims to delineate imaging characteristics that distinguish malignant from benign splenic lesions. Methods: Adhering to PRISMA guidelines, we searched PubMed, Scopus, and Web of Science for studies on imaging features differentiating malignant from benign splenic lesions. We extracted data on splenic pathology and imaging characteristics and assessed the methodological quality via QUADAS-2. Odds ratio meta-analyses were performed using STATA (Version 17.0, Stata Corp, College Station, TX). Results: Portal phase hypoenhancement, hypovascular enhancement pattern, diffusion restriction, and late phase hypoenhancement, with odds ratios above 10, highly indicate malignancy. Other features suggestive of malignancy include solid morphology, lymphadenopathy, presence of perisplenic fluid, arterial hypoenhancement, hypoechogenicity on ultrasound, splenomegaly, and presence of multiple lesions. In contrast, cystic morphology, hypervascular-washout and hypervascular-persistent pattern of enhancement, late phase hyperenhancement, anechogenicity on ultrasound, portal phase hyperenhancement, well-defined borders, and calcification are in favour of benign pathology. Conclusion: The study underscores the critical role of contrast-enhanced and diffusion-weighted imaging in distinguishing malignant from benign splenic lesions, emphasizing the role of features like portal phase hypoenhancement and restricted diffusion in diagnosing malignancies. Additionally, the study emphasizes the value of contrast-enhanced ultrasound, which allows for the visualization of key contrast-enhancement patterns without the risk of ionizing radiation exposure.

Canine adrenal gland volume can be predicted based on body weight and computed tomography (CT) measurements using a validated algorithm. Use of this algorithm to detect adrenal pathology, including hyperplasia, hypoplasia and neoplasia, in clinical cases has not been described. The objective of this study was to illustrate application of the algorithm by estimating subject‐specific adrenal gland volume in a historical cohort of dogs with known adrenal disease. Forty‐six dogs that underwent CT and subsequent adrenalectomy were included. Clinical records and CT images from dogs that underwent adrenalectomy and histologic examination of the excised adrenal gland(s) were reviewed. Normal adrenal gland volumes for each dog were estimated using the algorithm, and compared with measured volumes of the affected glands. Linear measurement of the largest lesion diameter was also recorded. Fifty‐eight adrenal glands were removed from 46 dogs, with pathology confirmed in all glands. Pathology included 28 adenomas, 13 carcinomas, 11 pheochromocytomas and 6 other benign pathologies. The volume of all removed adrenal glands was measured to be larger than the expected normal volume estimated by the algorithm, ranging from 1.1 to 212.9 times larger than estimated. Adrenal glands with malignant and benign pathology showed variable volumes with overlapping ranges recorded. Assessment of the dimensions of any focal lesion against a cut‐off of 20 mm failed to discriminate malignancy. This study illustrates and supports the application of a validated volumetric algorithm for estimation of subject‐specific adrenal gland volume to identify the presence of pathology and as a tool to assist clinical decision‐making.

Purpose of Review: Along with a strong impact on skeletal integrity, bone marrow adipose tissue (BMAT) is an important modulator of the adult hematopoietic system. This review will summarize the current knowledge on the causal relationship between bone marrow (BM) adipogenesis and the development and progression of hematologic malignancies. Recent Findings: BM adipocytes (BMAds) support a number of processes promoting oncogenesis, including the evolution of clonal hematopoiesis, malignant cell survival, proliferation, angiogenesis, and chemoresistance. In addition, leukemic cells manipulate surrounding BMAds by promoting lipolysis and release of free fatty acids, which are then utilized by leukemic cells via β-oxidation. Therefore, limiting BM adipogenesis, blocking BMAd-derived adipokines, or lipid metabolism obstruction have been considered as potential treatment options for hematological malignancies. Summary: Leukemic stem cells rely heavily on BMAds within the structural BM microenvironment for necessary signals which foster disease progression. Further development of 3D constructs resembling BMAT at different skeletal regions are critical to better understand these relationships in geometric space and may provide essential insight into the development of hematologic malignancies within the BM niche. In turn, these mechanisms provide promising potential as novel approaches to targeting the microenvironment with new therapeutic strategies. [ABSTRACT FROM AUTHOR]

Bilateral adrenal masses, increasingly encountered in clinical practice, manifest across diverse contexts, including incidental discovery, malignancy staging, and targeted imaging after hormonal diagnosis of adrenal disorders. The spectrum encompasses various pathologies, such as cortical adenomas, macronodular adrenal disease, pheochromocytomas, myelolipomas, infiltrative disorders, and primary and secondary malignancies. Notably, not all masses in both adrenal glands necessarily share the same etiology, often exhibiting diverse causes. Recently, the European Society of Endocrinology and the European Network for the Study of Adrenal Tumors updated guidelines, introduced a 4-option schema based on imaging, aiding in targeted hormonal testing and management. This "Approach to the Patient" review delves into the latest advancements in imaging, biochemical, and genetic approaches for the diagnostic and management nuances of bilateral adrenal masses. It provides insights and a contemporary framework for navigating the complexities associated with this clinical entity. [ABSTRACT FROM AUTHOR]

Objective To investigate strategies for preventing and controlling hospital acquired infections in children with acute lymphoblastic leukemia (ALL). Methods From January 2019 to June 2022. a total of 282 hospitalized children with acute lymphoblastic leukemia were enrolled from the Department of Hematology and Oncology of our hospital. They were randomly divided into the control group(n=138) and the observation group(n=144). Both groups received standard treatment and nursing care, while the observation group additionally implemented measures for preventing hospital acquired infections. The study compared the incidence of hospital acquired infections, infection sites, and overall health status between the two groups. Results In the control group, there were 22 cases and 25 episodes of hospital acquired infections, while in the observation group, there were 10 cases and 12 episodes. The incidence rates of hospital acquired infections were 15.94% and 6.94% in the control and observation group, respectively, with corresponding episode rates of 18.12% and 8.33%. Both infection rates and episode rates were significantly lower in the observation group compared to the control group(P<0.05). Upper respiratory tract was the predominant site of infection. with Gram-negative bacteria being the main pathogens identified. The Quality of Life (QOL) score in the observation group(69.87±3.41) was significantly higher than that in the control group (63.88±3.09) (P<0.05). Conclusion Implementing infection prevention and control strategies effectively reduces the incidence of hospital acquired infections in children with acute lymphoblastic leukemia, improves their overall health status, and mitigates negative emotional impacts.

Among the post‐transplantation complications that patients may encounter, the transmission of a donor‐derived malignant neoplasm is uncommon but potentially life threatening. The determination of donor versus recipient origin is essential particularly in the setting of multiple transplant recipients from the donor. Advances in molecular biology now allow accurate discrimination utilizing routine tissue samples in a timely and cost‐effective manner. The techniques are routinely performed in hospital molecular biology laboratories and are also available in commercial labs. The current methodologies are discussed and future possibilities are presented for clinicians caring for solid organ recipients. [ABSTRACT FROM AUTHOR]

Background: Nephrotic syndrome (NS) can occur as a paraneoplastic disorder in association with various types of carcinoma. However, paraneoplastic nephrotic syndrome (PNS) is often misdiagnosed as idiopathic nephrotic syndrome or as an adverse effect of oncology treatment, leading to delayed diagnosis and suboptimal treatment. The characteristics of NS associated with solid malignancies are not yet elucidated. We systematically summarized the clinical data for 128 cases of NS combined with solid malignancies with the aim of informing the clinical management of PNS. Methods: We searched the PubMed database for articles published from the date of inception through to October 2023 using the following keywords: "cancer" or "malignant neoplasms" or "neoplasia" or "tumors" and "nephrotic syndrome", "nephrotic" or "syndrome, nephrotic". All data were extracted from case reports and case series, and the extraction included a method for identifying individual-level patient data. Results: A literature search yielded 105 cases of PNS and 23 of NS induced by cancer therapy. The median age at diagnosis was 60 years, with a male to female ratio of 1.8:1. In patients with PNS, manifestations of NS occurred before, concomitantly with, or after diagnosis of the tumor (in 36%, 30%, and 34% of cases, respectively). Membranous nephropathy (49%) was the most prevalent renal pathology and found particularly in patients with lung, colorectal, or breast carcinoma. Regardless of whether treatment was for cancer alone or in combination with NS, the likelihood of remission was high. Conclusion: The pathological type of NS may be associated with specific malignancies in patients with PNS. Prompt identification of PNS coupled with suitable therapeutic intervention has a significant impact on the outcome for patients. [ABSTRACT FROM AUTHOR]

Introduction: Fine Needle Aspiration Cytology (FNAC) of the lymph node is a simple tool in the diagnosis of suspected and unsuspected primary and secondary lymph node malignancy. It is a useful first-line investigation to distinguish between infective and malignant lymphadenopathy, especially in a low-resource setting like our country. Aim: To study the utility of FNAC in the diagnosis of lymph node malignancy and to evaluate the efficacy of cytology in diagnosing the primary site of malignancy in case of metastasis. Materials and Methods: A cross-sectional retrospective and prospective study was conducted for a five-year period from July 2015 to June 2020, in the pathology department of Dr. RN Cooper Municipal General Hospital, Mumbai, Maharashtra, India. A total of 112 patients diagnosed with malignancy on FNAC of lymph nodes were studied. The FNAC procedure was performed by cytopathologists using a 23/24G needle attached to a 10 ml syringe. The alcohol-fixed smears were stained with Haematoxylin & Eosin (H&E) stain and Papanicolaou (PAP) stains, while the airdried smears were stained with Giemsa stain. Diagnosis was based on cytomorphological features and clinical presentation. Results: A total of 112 patients were diagnosed with malignancy on FNAC, of which 90 were males and 22 were females, with a male-to-female ratio of 4:1. Cytological analysis of these nodes revealed metastasis in 98 cases (87.50%) and lymphoma in 14 cases (12.50%). The maximum number of patients were in the 51-60 years age group, with 38 cases (33.92%). The most common site of involvement was cervical lymph nodes, with 75 cases (66.96%). The most common cytological diagnosis was metastatic squamous cell carcinoma in 65 cases (58.02%), followed by metastatic un-differentiated carcinoma in 26 cases (23.20%). Conclusion: Fine Needle Aspiration (FNA) is a simple, safe, accurate, cost-effective, and valuable tool in the evaluation of malignant lymphadenopathy. Malignant diseases were easily diagnosed by this simple diagnostic procedure. In the case of a diagnosis of lymphoma, surgery can be completely avoided. It helps in planning further surgical management for metastatic disease, where definitive operative intervention can be performed in one session. In the case of an un-detected primary tumour, FNAC directs further investigations towards the possible primary site. [ABSTRACT FROM AUTHOR]

This report presents a unique case of an endocervical polyp-mimicking malignancy on pelvic MRI in a 45-year-old female. The MRI depicted a multilocular cystic lesion with an enhancing solid component, raising suspicion for malignancy. However, histopathological examination definitively revealed a benign endocervical polyp. This case highlights the limitations of diagnosing cervical lesions solely on MRI features, emphasizing the potential for benign conditions to mimic malignancy. [ABSTRACT FROM AUTHOR]

Background: The use of ultrasound aids in the identification of thyroid nodules, but it is still crucial to determine whether or not they are problematic using non-invasive methods. Aim of work: To evaluate validity of TIRADS in diagnosis of nature of thyroid nodules. Patients and methods: A cross sectional study was conducted on 95 nodules derived from thirty patients in radio diagnosis department in Zagazig University hospital from February 2018 to June 2019. All patients underwent complete history taking, full clinical examination, ultrasonographic evaluation of thyroid gland and Fine needle aspiration cytology (FNAC) for solitary nodule or the most suspicious nodules in patients with multinodular goiter and then smears were pathologically assessed. Results: About 73% of patients were females with mean age 46 years. Out of the ninety-five nodules, fifty were assesses using US-guided FNAB. Ten nodules were malignant. Papillary carcinoma was the most common accounting for seven nodules. Thyroid Imaging Reporting and Data System (TIRADS) 3 was the most commonly encountered category accounting (42%) while The different TIRADS categories were confronted with the results of pathology and the risk of malignancy were Compared with benign nodules, significantly higher percentages of malignant nodules wee solid, hypoechoic, with irregular margins, taller-than-wide morphology, with microcalcifications, markedly hypoechoic or associated abnormal cervical lymphadenopathy. Tab and T5 predict malignant nature of nodule with sensitivity 90%, specificity 95%, and 95% accuracy. Conclusions: Russ' modified TIRADS classification is reliable in both stratifying nodular thyroid disease based on the risk of malignancy and predicting thyroid malignancy. [ABSTRACT FROM AUTHOR]

Breast cancer (BC) and depression are globally prevalent problems. Numerous reviews have indicated the high prevalence of depression among BC survivors. However, the long-term impact of depression on survival among BC survivors has not been well explored. For this investigation, we aimed to explore the relationship between BC, depression, and mortality from a national random sample of adult American women. Data from the U.S. National Health and Nutrition Examination Survey (years 2005–2010) were linked with mortality data from the National Death Index up to December 31st, 2019. A total of 4719 adult women (ages 45 years and older) were included in the study sample with 5.1% having breast cancer and more than a tenth (12.7%) having depression. The adjusted hazard ratio (HR) for all-cause mortality risk among those with BC was 1.50 (95% CI = 1.05–2.13) compared to those without BC. In the adjusted analysis, the risk of all-cause mortality was highest among women with both depression and BC (HR = 3.04; 95% CI = 1.15–8.05) compared to those without BC or depression. The relationship between BC and mortality was moderated by cardiovascular diseases, anemia, smoking, age, PIR, and marital status. Our analysis provides vital information on factors that could be helpful for interventions to reduce mortality risk among those with BC and depression. In addition, given the higher risk of mortality with co-occurring BC and depression, collaborative healthcare practices should help with widespread screening for and treatment of depression among BC survivors.

Tetracyclines constitute a unique class of antibiotic agents, widely prescribed for both community and hospital infections due to their broad spectrum of activity. Acting by disrupting protein synthesis through tight binding to the 30S ribosomal subunit, their interference is typically reversible, rendering them bacteriostatic in action. Resistance to tetracyclines has primarily been associated with changes in pump efflux or ribosomal protection mechanisms. To address this challenge, tetracycline molecules have been chemically modified, resulting in the development of third-generation tetracyclines. These novel tetracyclines offer significant advantages in treating infections, whether used alone or in combination therapies, especially in hospital settings. Beyond their conventional antimicrobial properties, research has highlighted their potential non-antibiotic properties, including their impact on immunomodulation and malignancy. This review will focus on third-generation tetracyclines, namely tigecycline, eravacycline, and omadacycline. We will delve into their mechanisms of action and resistance, while also evaluating their pros and cons over time. Additionally, we will explore their therapeutic potential, analyzing their primary indications of prescription, potential future uses, and non-antibiotic features. This review aims to provide valuable insights into the clinical applications of third-generation tetracyclines, thereby enhancing understanding and guiding optimal clinical use.

Monogenic diseases of immune dysregulation should be considered in the evaluation of children presenting with recurrent neutrophilic dermatoses in association with systemic signs of inflammation, autoimmune disease, hematologic abnormalities, and opportunistic or recurrent infections. We report the case of a 2‐year‐old boy presenting with a neutrophilic dermatosis, found to have a novel likely pathogenic germline variant of the IKAROS Family Zinc Finger 1 (IKZF1) gene; the mutation likely results in a loss of function dimerization defective protein based on reports and studies of similar variants. IKZF1 variants could potentially lead to aberrant neutrophil chemotaxis and development of neutrophilic dermatoses. Long‐term surveillance is required to monitor the development of hematologic malignancy, autoimmunity, immunodeficiency, and infection in patients with pathogenic IKZF1 germline variants.

Objectives Paraneoplastic arthritis (PA) is one of the paraneoplastic syndromes. Both laboratory and clinical findings similar to rheumatological diseases can be seen. In this study we aimed to present the clinical and laboratory findings, malignancy types and pathological diagnoses of patients with paraneoplastic arthritis. Methods In a multicentre retrospective study, 92 patients with PA from the last 10 years were included. Results Patients with PA and haematological malignancies exhibited the highest ratio of lymphomas (25.6%). The most common cancer detected in patients with solid malignancy and PA was lung cancer (41.5%). All malignant patients with PA had significant anti-CCP positivity compared with the healthy control group (P  = 0.014). Conclusion Although PA is a rare condition, it can be confused with many rheumatological diseases. The most commonly involved joint is the knee joint, followed by the ankle and hand/wrist. Autoantibody negativity, high lactate dehydrogenase level and arthritis unresponsive to treatment constitute important clues for diagnosis. [ABSTRACT FROM AUTHOR]

Objectives: To generate and validate a prediction model based on imaging features for cancer risk of non-mass lesions (NMLs) detected on breast ultrasound (US). Methods: In this single-center study, consecutive women with 503 NMLs detected on breast US between 2012 and 2019 were retrospectively identified. The lesions were randomly assigned to the training or testing dataset with a 70/30 split. Age, symptoms, lesion size, and US features were collected. Multivariate analyses were employed to identify risk factors associated with malignancy. The predictive model was developed by using conditional inference trees (CTREE). Results: There were 498 patients (50.9 ± 13.29 years; range, 22–88 years) with 503 NMLs with histopathologic results or > 2-year follow-up, including 224 (44.5%) benign and 279 (55.5%) malignant lesions. At multivariate analysis, age (odds ratio (OR) = 1.08, 95% confidence interval (CI), 1.06–1.11, p < 0.001), NMLs with focal mass effect (OR = 3.03, 95% CI, 1.59–5.81, p = 0.001), indistinct glandular–fat interface (GFI) (OR = 4.23, 95% CI, 2.31–7.73, p < 0.001), geographic (OR = 3.47, 95% CI, 1.20–10.8, p = 0.022) and mottled (OR = 3.67, 95% CI, 1.32–10.21, p = 0.013) patterns, and calcifications (OR = 2.15, 95% CI, 1.16–4.01, p = 0.016) were associated with malignancy. The GFI status, architectural patterns, general morphology, and calcifications were consistently identified as the strongest US predictors of malignancy using CTREE analysis. Based on these factors, individuals were stratified into six risk groups. The predictive model showed an area under the curve of 0.797 in the testing dataset. Conclusion: The CTREE model efficiently aids in interpreting and managing ultrasound-detected breast NMLs, overcoming BI-RADS limitations by refining cancer risk stratification. Clinical relevance statement: The CTREE model allows for the reclassification of BI-RADS categories into subgroups with varying malignancy probabilities, thus providing a valuable enhancement to the BI-RADS assessment for the diagnosis of ultrasound-detected NMLs, with the potential to minimize unnecessary biopsies. Key Points: • The indistinct glandular–fat interface (GFI) status, NML with focal mass effect, geographic or mottled patterns, and calcifications are the strongest imaging predictors of malignant non-mass lesions (NMLs) detected on breast US. • A practical system has been created to categorize NMLs found in breast US; each classification is associated with a degree of diagnostic certainty. • The model may contribute to patient stratification by determining the relative likelihood of malignancy and thus support clinical decision-making and evidence-based management.

We aimed to describe features and outcomes of cryptococcosis among HIV-seronegative individuals in a large surveillance network for cryptococcosis in France. We included incident cases of cryptococcosis in HIV-seronegative individuals from 2005 to 2020. We compared patient characteristics, disease presentations, cryptococcal antigen results, and induction antifungal treatments according to underlying disease. We examined factors associated with 90-day mortality. Among patients with disseminated infections, we investigated whether receipt of flucytosine and polyene combination was associated with lower mortality. Among 652 individuals, 209 (32.1%) had malignancy, 130 (19.9%) were solid-organ transplant recipients, 204 (31.3%) had other immunocompromising conditions, and 109 (16.7%) had no reported underlying factor. The commonest presentations were disseminated infections (63.3%, 413/652) and isolated pulmonary infections (25.3%, 165/652). Solid-organ transplant patients were most likely to have disseminated infections and a positive serum cryptococcal antigen result. Patients with malignancy were older and less likely to receive a flucytosine-containing regimen for disseminated infections than others (58.7%, 78/133 vs. 73.2%, 194/265; p 0.029). The crude 90-day case-fatality ratio was 27.2% (95% CI, 23.5%–31.1%). Age ≥60 years (aOR: 2.75 [1.78–4.26]; p < 0.001), meningitis/fungaemia (aOR: 4.79 [1.80–12.7]; p 0.002), and malignancy (aOR: 2.4 [1.14–5.07]; p 0.02) were associated with higher 90-day mortality. Receipt of flucytosine and polyene combination was associated with lower 90-day mortality (aOR: 0.40 [0.23–0.71]; p 0.002) in multivariable analysis and inverse probability of treatment weighted analysis (aOR: 0.45 [0.25–0.80]; p 0.006). HIV-seronegative individuals with cryptococcosis comprise a wide range of underlying conditions with different presentations and outcomes, requiring a tailored approach to diagnosis and management.

Peroxiredoxin 6 (PRDX6) is an atypical member of the peroxiredoxin family that presents not only peroxidase but also phospholipase A2 and lysophosphatidylcholine acyl transferase activities able to act on lipid hydroperoxides of cell membranes. It has been associated with the proliferation and invasive capacity of different tumoral cells including colorectal cancer cells, although the effect of its removal in these cells has not been yet studied. Here, using CRISPR/Cas9 technology, we constructed an HCT116 colorectal cancer cell line knockout for PRDX6 to study whether the mechanisms described for other cancer cells in terms of proliferation, migration, and invasiveness also apply in this tumoral cell line. HCT116 cells lacking PRDX6 showed increased ROS and lipid peroxidation, a decrease in the antioxidant response regulator NRF2, mitochondrial dysfunction, and increased sensitivity to ferroptosis. All these alterations lead to a decrease in proliferation, migration, and invasiveness in these cells. Furthermore, the reduced migratory and invasive capacity of HCT116 cancer cells is consistent with the observed cadherin switch and decrease in pro-invasive proteins such as MMPs. Therefore, the mechanism behind the effects of loss of PRDX6 in HCT116 cells could differ from that in HepG2 cells which is coherent with the fact that the correlation of PRDX6 expression with patient survival is different in hepatocellular carcinomas. Nonetheless, our results point to this protein as a good therapeutic target also for colorectal cancer. [ABSTRACT FROM AUTHOR]

There is a close relationship between immune‐mediated inflammation and cancer, and there is still controversy over whether rheumatoid arthritis (RA) increases the risk of malignancy. We first used Mendelian randomization (MR) analysis to explore the potential causal relationship between RA and pan‐cancer. And verify the effect of immune‐mediated inflammation on cancer through intermediate MR analysis. Then we extracted the standardized incidence rate of malignancy in RA patients relative to the general population through large‐scale meta‐analysis. Finally, we performed pan‐cancer analysis on the RA related genes obtained from MR analysis. And perform immune related analysis on key genes to reveal the association between RA and malignancy. The MR analysis demonstrated a negative correlation between RA and pan‐cancer (p = 0.008). Autoimmune traits were the main mediating variable for the causal relationship between RA and pan‐cancer. Based on the results of the meta‐analysis, we validated that RA reduces the risk of developing colorectal cancer (SIR = 0.69, 95% CI 0.53–0.85). Pan‐cancer analysis also showed that high expression of RA related genes was negatively correlated with colon adenocarcinoma. IL6R was the gene with the highest correlation among them, and its correlation with immune cells was higher in colorectal cancer than in other malignancy. Our MR study provides evidence that RA was associated with reduced risk of colorectal cancer. This effect is caused by immune‐mediated inflammation, with IL6R being a key regulatory gene.

The Wnt/β-Catenin pathway (Wnt/β-CatP) is implicated in accelerating carcinogenesis and cancer progression, contributing to increased morbidity and treatment resistance. Even though it holds promise as a focus for cancer treatment, its intricate nature and diverse physiological effects pose significant challenges. Recent years have witnessed significant advancements in this domain, with numerous natural products demonstrating promising preclinical anti-tumor effects and identified as inhibitors of the Wnt/β-CatP through various upstream and downstream mechanisms. This study provides a comprehensive overview of the current landscape of Wnt/β-Cat-targeted cancer therapy, examining the impact of natural products on Wnt/β-Cat signaling in both cancer prevention and therapeutic contexts. A comprehensive search was conducted on scientific databases like SciFinder, PubMed, and Google Scholar to retrieve relevant literature on Wnt-signaling, natural products, β-Catenin (β-Cat), and cancer from 2020 to January 2024. As per the analysis of the relevant reference within the specified period, it has been noted that a total of 58 phytoconstituents, predominantly phenolics, followed by triterpenoids and several other classes, along with a limited number of plant extracts, have exhibited activity targeting the Wnt/β-CatP. Most β-Cat regulating modulators restrict cancer cell development by suppressing β-Cat expression, facilitating proteasomal degradation, and inhibiting nuclear translocation. Multiple approaches have been devised to block the activity of β-Cat in cancer therapy, a key factor in cancer progression, leading to the discovery of various Wnt/β-CatP regulators. However, their exploration remains limited, necessitating further research using clinical models for potential clinical use in cancer prevention and therapeutics. [ABSTRACT FROM AUTHOR]
