UNASSIGNED: Immunotherapy offers new hope for cancer patients but presents new medical challenges for healthcare workers in terms of the management of immune-related adverse events (irAEs). The clinical data of two patients with advanced thymoma (T) admitted to the Fujian Cancer Hospital who developed fulminant myocarditis after undergoing immunosuppressant therapy were analyzed retrospectively, and the relevant literature was reviewed. This study aims to examine treatment of thymic epithelial tumors (TETs)-associated immune myocarditis.
UNASSIGNED: An online search was conducted to retrieve relevant full-text articles, and the selected articles were assessed. In total, 13 articles, comprising the data of 113 patients, were included in an analysis to evaluate the efficacy of immunotherapy. Of the 113 patients, 19 had T and 94 had thymic carcinoma (TC). Of the 19 patients with T, 10 (52.6%) achieved a partial response (PR), 8 (42.1%) had stable disease (SD), and 1 (5.3%) had progressive disease (PD). Of the 94 patients with TC, 1 (1.1%) achieved a complete response (CR), 20 (21.3%) achieved a PR, 51 (54.3%) had SD, and 22 (23.4%) had PD. Five articles reported that fulminant myocarditis developed in nine thymic epithelioma patients who were treated with immunosuppressive agents. Two TC patients who presented with fulminant myocarditis were treated with high-dose corticosteroid therapy and underwent pacemaker insertion; none of the patients died of immune myocardial toxicity. However, of the seven T patients who received high-dose corticosteroid therapy and immunoglobulin therapy, and underwent pacemaker implantation, three survived and four died.
UNASSIGNED: Immunotherapy has shown promising results in the treatment of patients with refractory or relapsed TETs. Due to their susceptibility to paraneoplastic autoimmunity, TET patients are at a higher risk of developing severe irAEs than patients with other types of cancer. Given the relatively high morbidity and mortality of irAEs, the administration of immune checkpoint inhibitors (ICIs) to treat TETs should be balanced against the clinical response and the precipitation of potentially severe irAEs.

UNASSIGNED: To evaluate the efficacy and safety of high-intensity focused ultrasound (HIFU) ablation in the treatment of uterine arteriovenous fistula (UAVF).
UNASSIGNED: This case series included three patients diagnosed with acquired UAVF. All patients underwent routine laboratory tests, electrocardiography (ECG), chest X-ray, ultrasound, and pelvic contrast-enhanced magnetic resonance imaging (MRI). HIFU treatment was performed under sedation and analgesia using a Model JC Focused Ultrasound Tumor Therapeutic System (made by Chongqing Haifu Medical Technology Co. Ltd., China) with a B mode ultrasound device for treatment guidance. The treatment time, sonication power, sonication time, and complications were recorded. Follow-up evaluations were scheduled at 1-, 3-, 6-, and 12-month to assess symptom improvement and evaluate the post-treatment imaging.
UNASSIGNED: All patients completed HIFU treatment in a single session without any major complication. All patients complained of mild lower abdominal and sacrococcygeal pain. Typically, no special treatment is required. Following HIFU treatment, there was a significant relief in clinical symptoms, particularly abnormal uterine bleeding. Ultrasound examinations conducted one month after the treatment revealed a notable reduction in the volume of the lesion, ranging from 57% to 100%. Moreover, the efficacy and safety of HIFU treatment remained consistent during the 12-month follow-up period.
UNASSIGNED: HIFU ablation appears to be an effective and safe treatment modality for UAVF. It provides a noninvasive approach with favorable clinical outcomes.

UNASSIGNED: The aim of this retrospective study was to investigate the short-term and long-term efficacy of high-intensity focused ultrasound (HIFU) therapy for abdominal wall endometriosis (AWE) and explore its potential influencing factors.
UNASSIGNED: A total of 80 patients with AWE who underwent HIFU therapy were retrospectively analyzed. Follow-ups were also conducted to evaluate the changes in lesion size and pain relief. Multivariate logistic regression analysis was applied to investigate factors influencing HIFU therapy for AWE.
UNASSIGNED: Among the 80 patients with AWE who received HIFU therapy, the effective rates were 76.3%, 80.5%, and 90.5% after 3, 12 and 24 months of follow-up, respectively. Multivariate logistic regression analysis revealed that the AWE lesion diameter and sonication intensity had statistically significant effects on the 3-month and 12-month efficacy of HIFU therapy for AWE, while age, BMI, disease duration, average sonication power and grey-scale changes did not have statistically significant effects. Four patients with AWE experienced recurrence after HIFU therapy, for a three-year cumulative recurrence rate of 6.3%. Furthermore, ten patients required reintervention after treatment, for a five-year cumulative reintervention rate of 13.9%.
UNASSIGNED: This study further confirmed the safety and effectiveness of HIFU therapy for AWE. Factors such as AWE lesion diameter and sonication intensity have been identified as key influencers affecting the short-term and long-term efficacy of HIFU therapy for AWE. The first two years following HIFU therapy constitute crucial periods for observation, and judiciously extending follow-up intervals during this timeframe is advised.

UNASSIGNED: Infantile hepatic hemangioma (IHH) is a common vascular, fast-growing hepatic tumor that is usually accompanied by multiple cutaneous hemangiomas. Diffuse IHH (DIHH) is a rare type of IHH that exhibits many tumors with nearly complete hepatic parenchymal replacement. At present, there is no specific standardized treatment plan for DIHH. Herein, we present the case of a 2-month-old girl with DIHH and without cutaneous hemangioma who achieved complete remission after undergoing propranolol monotherapy.
UNASSIGNED: The infant with low birth weight was presented to the pediatric department with a 2-month history of persistent vomiting and feeding difficulty. Ultrasonography and abdominal magnetic resonance imaging revealed hepatomegaly and diffused intrahepatic lesions. A computed tomography-guided percutaneous liver biopsy was performed, and the pathological examination suggested the diagnosis was DIHH. The patient exhibited remarkably response to an increasing dose of oral propranolol, from 0.5 mg/kg to 2 mg/kg every day. The intrahepatic lesions were almost completely regressed after one year of treatment and no distinct adverse reaction was observed.
UNASSIGNED: DIHH can induce life-threatening complications that require prompt interventions. Propranolol monotherapy can be an effective and safe first-line treatment strategy for DIHH.

A 15-year-old girl had experienced hip pain at 11 years of age. At 15 years of age, the patient complained of persistent generalised pain. Her rheumatoid factor and serum matrix metalloproteinase-3 levels were below standard values; there were no inflammatory responses, and the human leukocyte antigen test was negative for B27 and positive for B52 and B62. The bath ankylosing spondylitis disease activity index (BASDAI) value was 8.0 at the time of induction and 3.1 at 6 months after the introduction of adalimumab (at a dose of 40 mg). The BASDAI value improved with an increase in the dose of adalimumab to 80 mg at 8 months after the initial introduction of adalimumab (at 40 mg), although it remained at 4.8 at 16 months after the dose increase. The BASDAI value was 2.6 at 6 months, 2.7 at 1 year, and 1.8 at 1.5 years after the introduction of infliximab, indicating that the patient had progressed well without any adverse events. Based on this case, juvenile ankylosing spondylitis is a differential diagnosis for low back pain and generalised pain since childhood. Tumour necrosis factor (TNF) inhibitors were promptly introduced in this case, although it took 4 years from the initial presentation. TNF inhibitors were effective in treating juvenile ankylosing spondylitis in the present case without any adverse events. This case is notable because juvenile onset ankylosing spondylitis is one of the reasons for severe lumbago since childhood and because TNF inhibitors were administered promptly after diagnosis.

BACKGROUND: In nonsmall cell lung cancer (NSCLC), epidermal growth factor receptor (EGFR) mutation is the primary cancer-causing mutation. But whether the practical effectiveness of EGFR tyrosine kinase inhibitors (TKIs) can be influenced by plasma EGFR mutation abundance when treating patients with advanced NSCLC remains unanswered. Therefore, this research was intended to reveal the connection between plasma EGFR mutation abundance and clinical outcomes in osimertinib-treated patients with advanced NSCLC.
METHODS: A total of 120 patients with advanced NSCLC were retrospectively analyzed, and 56 patients with EGFR-mutation-positive NSCLC receiving osimertinib first-line therapy were eventually screened and included. The baseline status and abundance of plasma EGFR in patients with NSCLC were detected by cSMART, and the ratio of 0.1 was the critical value. Imaging examinations were performed every 8-12 weeks for the assessment of tumor response. The relationship between baseline EGFR mutation abundance and clinical outcomes of TKI therapy was analyzed.
RESULTS: The objective response rates (ORR) of EGFR-mutant patients in the high-/low-abundance groups were 69.2% and 40.0%, respectively. The high abundance group had an obviously higher ORR than the low abundance group (P = 0.029). A much longer median progression-free survival (mPFS) was demonstrated in patients with high mutation abundance than in patients with low abundance (11.2 months vs 7.1 months, P = 0.0133). As for the median overall survival (mOS), it showed the same trend as mPFS in patients from different groups (15.5 vs 10.7 months, P = 0.0028). The role of plasma mutation abundance as an independent prognostic factor for both PFS (hazard ratios [HR]: 0.30, P = 0.006) and OS (HR: 0.35, P = 0.004) was demonstrated by multivariate Cox regression analysis.
CONCLUSIONS: There is a close connection between plasma EGFR mutation abundance and survival benefit in patients with NSCLC, which can be used for predicting the efficacy of EGFR-TKI targeted therapy. Our study is expected to provide a research basis for screening patients to whom the EGFR-TKI therapy is beneficial.

Anal adenocarcinoma combined with perianal Paget\'s disease (PPD) involving the vulva is rare, and there is no established standard treatment. We present the case of a 69-year-old woman with symptoms of intermittent hematochezia and perianal discomfort for 7 months. Upon examination, we discovered a plaque-like hard mass on the right posterior wall of the anal canal, which extended to encompass the anus and dentate line. The lesion skin also extended forward from the gluteal groove, involving the bilateral labial area. Colonoscopy revealed an extensive protruding lesion on the dentate line, which was confirmed as anal adenocarcinoma (mrT4N0M0). The presence of Paget\'s cells in perianal and vulvar skins led to the diagnosis of PPD. The strategy of neoadjuvant chemoradiotherapy (nCRT) followed by radical surgery was then made after multi-disciplinary discuss. The scope and extent of perianal and vulvar disease were significantly diminished after nCRT. The patient underwent laparoscopic abdominoperineal resection and vulvar lesion resection, confirming the diagnosis of anal adenocarcinoma (ypT2N0). No evidence of tumor cells was found in perianal and vulvar skin, indicating a complete response. The patient is regularly monitored without recurrence or metastasis.

Endoscopic transsphenoidal surgery (ETSS) for prolactinoma is reserved for dopamine agonist (DA) resistance, intolerance, or apoplexy. High remission (overall 67%, microprolactinoma up to 90%), low recurrence (5-20%) rates highlighted that surgery might be first-line treatment.
To report on outcomes of ETSS in a cohort of prolactinomas.
Multicenter retrospective cohort of 137 prolactinoma patients (age 38.2 ± 13.7 years; 61.3% female, median follow-up 28.0 [15.0-55.5] months) operated between 2010-2019 with histopathological confirmation.
Median preoperative prolactin levels were 166 (98-837 µg/L; males 996 [159-2145 µg/L] vs. females 129 [84-223 µg/L], p <0.001). 56 (40.9%) microprolactinomas, 69 (50.4%) macroprolactinomas, and 7 (5.1%) giant prolactinomas were included, whereas no adenoma was detected in 5 (3.6%) patients. Males had larger tumors (macroprolactinomas: 38, 71.7%) vs. 31 (36.9%), p <0.001; giant prolactinomas: 7 (13.2%) vs. 0 (0.0%), (p <0.001). Prolactinomas were graded as KNOSP-3 in 15 (11.5%), and KNOSP-4 in 20 (15.3%) patients. Primary indication was DA intolerance (59, 43.1%); males 14 (26.4%) vs. females 45 (53.6%), p = 0.006. Long-term remission (i.e., DA-free prolactin level <1xULN) was achieved in 87 (63.5%) patients, being higher in intended complete resection (69/92 [75.0%]), and lower in males (25 [47.2%] vs. 62 females [73.8%], p = 0.002). Transient DI (n = 29, 21.2%) was the most frequent complication.
Despite high proportions of macroprolactinoma and KNOSP 3-4, long-term remission rates were 63.5% overall, and 83.3% in microprolactinoma patients. Males had less favorable remission rate compared to females. These findings highlight that ETSS may be a safe and efficacious treatment to manage prolactinoma.
