Genomic instability (GI) was associated with tumorigenesis. However, GI-related lncRNA signature (GILncSig) in lung adenocarcinoma (LUAD) is still unknown. In this study, the lncRNA expression data, somatic mutation information and clinical survival information of LUAD were downloaded from The Cancer Genome Atlas (TCGA) and performed differential analysis. Functional and prognosis analysis revealed that multiple GI-related pathways were enriched. By using univariate and multivariate Cox regression analysis, 5 GI-associated lncRNAs (AC012085.2, FAM83A-AS1, MIR223HG, MIR193BHG, LINC01116) were identified and used to construct a GILncSig model. Mutation burden analysis indicated that the high-risk GI group had much higher somatic mutation count and the risk score constructed by the 5 GI-associated lncRNAs was an independent predictor for overall survival (OS) (P < 0.05). Overall, our study provides valuable insights into the involvement of GI-associated lncRNAs in LUAD and highlights their potential as therapeutic targets.

Review
Endoscopic ultrasound-guided tissue acquisition (EUS-TA), including fine-needle aspiration (EUS-FNA) and fine-needle biopsy (EUS-FNB), has revolutionized specimen collection from intra-abdominal organs, especially the pancreas. Advances in personalized medicine and more precise treatment have increased demands to collect specimens with higher cell counts, while preserving tissue structure, leading to the development of EUS-FNB needles. EUS-FNB has generally replaced EUS-FNA as the procedure of choice for EUS-TA of pancreatic cancer. Various techniques have been tested for their ability to enhance the diagnostic performance of EUS-TA, including multiple methods of sampling at the time of puncture, on-site specimen evaluation, and specimen processing. In addition, advances in next-generation sequencing have made comprehensive genomic profiling of EUS-TA samples feasible in routine clinical practice. The present review describes updates in EUS-TA sampling techniques of pancreatic lesions, as well as methods for their evaluation.

Appendicitis is a common surgical emergency marked by inflammation of the appendix, often due to blockage of the appendix lumen by fecoliths, lymphoid hyperplasia, or neoplasms. While various causes are known, appendicitis triggered by a foreign body (FB) is exceptionally rare. This case report highlights a rare presentation of appendicitis in a 32-year-old male with no significant medical history, who presented with acute lower right abdominal pain, fever, and vomiting. Initial evaluation suggested appendicitis, further supported by laboratory findings and diagnostic imaging revealing a retrocecal appendix with surrounding inflammation. Remarkably, an FB, a fish bone, was discovered lodged within the perforated appendix, elucidating the unusual etiology. Emergency laparotomy confirmed the diagnosis and facilitated prompt surgical intervention. This case underscores the importance of thorough evaluation and consideration of uncommon causes in patients presenting with acute abdominal pain, illustrating the critical role of detailed history-taking and clinical acumen in guiding management decisions and ensuring favorable patient outcomes.

Ovarian cystadenomas are benign epithelial neoplasms, many of which are of the serous subtype. Most patients present with symptoms such as abdominal pain, bloating, and bladder issues. This patient, who had a BMI of 45, presented with a giant ovarian serous cystadenoma identified during an elective bariatric surgery; interestingly, she was completely asymptomatic at the time of discovery. A large, predominantly cystic pelvic mass with internal septations and soft tissue components, suspicious for ovarian neoplasm, was discovered on a CT abdomen and pelvis with IV contrast. She underwent an exploratory laparotomy with complete resection, right oophorectomy, and ovarian cystectomy. Her postoperative pathology report revealed the mass to be a benign serous cystadenoma. This case serves as an example of how a massive tumor can potentially get overlooked for many years, only to be detected unintentionally in an asymptomatic patient. Healthcare quality is often negatively impacted by the inherent prejudice that many healthcare providers have toward their obese patients. Providers may mistakenly over-attribute a patient's symptoms to their obesity, failing to effectively evaluate the patient's concerns, which could lead to overlooking potentially harmful diagnoses. A comprehensive history and physical exam in all patients, especially those who are obese, is vital in ensuring timely diagnosis and management to improve patient outcomes.

This case report discusses a diagnosis of uterine torsion in an 84-year-old woman who presented with five days of right lower quadrant abdominal pain, nausea, vomiting, constipation, and poor intake. Computed tomography (CT) imaging demonstrated a whorled configuration at the junction of the cervix and lower uterine segment, with the left gonadal vein crossing midline, and two previously known right leiomyomas now appearing on the left. These findings were consistent with the diagnosis of uterine torsion. She then underwent an urgent exploratory laparotomy, and the uterus was found to be dextroverted 270 degrees, with dark mottled purple tissue and engorged vessels. A supracervical hysterectomy and bilateral salpingo-oopherectomy were performed. Final pathology demonstrated extensive necrosis. This case reviews the classic presentation and imaging findings for the rare diagnosis of uterine torsion and options for management of both non-gravid and gravid patients.

BMC Veterinary Research Jun 2024This study aims to describe a rare case of primary ureteral hemangiosarcoma, in which surgical intervention preserved the kidney and ureter after tumor removal.
BACKGROUND
This study aims to describe a rare case of primary ureteral hemangiosarcoma, in which surgical intervention preserved the kidney and ureter after tumor removal.
CASE PRESENTATION
A 13-year-old, neutered male dog, weighing 14 kg, mixed-breed, presented with apathy, anorexia, acute-onset vomiting, and abdominal discomfort during the physical examination. Ultrasonography and pyelography revealed a right-sided dilation of the renal pelvis and ureter due to complete obstruction in the middle third of the ureter. A mass obstructing the lumen of the right ureter was completely resected, and ureteral suturing was performed, preserving the integrity of the involved structures. Histopathology confirmed primary ureteral hemangiosarcoma. Due to the local and non-invasive nature of the mass, chemotherapy was not initiated. The patient's survival was approximately two years, and normal renal function was preserved throughout this period.
CONCLUSIONS
Considering this type of tumor in the differential diagnosis of upper urinary tract obstructive disorders. Furthermore, the preservation of the ureter and kidney is a suitable therapeutic option after surgical resection of non-invasive tumors.

OBJECTIVE
The incidence of recurrent hernia after radical resection of prostate cancer is high, so this article discusses the incidence and risk factors of inguinal hernia after radical resection of prostate cancer.
METHODS
This case control study was conducted in The First People's Hospital of Huzhou clinical data of 251 cases underwent radical resection of prostate cancer in this hospital from March 2019 to May 2021 were retrospectively analyzed. According to the occurrence of inguinal hernia, the subjects were divided into study group and control group, and the clinical data of each group were statistically analyzed, Multivariate Logistic analysis was performed to find independent influencing factors for predicting the occurrence of inguinal hernia. The Kaplan-Meier survival curve was drawn according to the occurrence and time of inguinal hernia.
RESULTS
The overall incidence of inguinal hernia after prostate cancer surgery was 14.7% (37/251), and the mean time was 8.58 ± 4.12 months. The average time of inguinal hernia in patients who received lymph node dissection was 7.61 ± 4.05 (month), and that in patients who did not receive lymph node dissection was 9.16 ± 4.15 (month), and there was no significant difference between them (P > 0.05). There were no statistically significant differences in the incidence of inguinal hernia with age, BMI, hypertension, diabetes, PSA, previous abdominal operations and operative approach (P > 0.05), but there were statistically significant differences with surgical method and pelvic lymph node dissection (P < 0.05). The incidence of pelvic lymph node dissection in the inguinal hernia group was 24.3% (14/57), which was significantly higher than that in the control group 11.8% (23/194). Logistic regression analysis showed that pelvic lymph node dissection was a risk factor for inguinal hernia after prostate cancer surgery (OR = 0.413, 95%Cl: 0.196-0.869, P = 0.02). Kaplan-Meier survival curve showed that the rate of inguinal hernia in the group receiving pelvic lymph node dissection was significantly higher than that in the control group (P < 0.05).
CONCLUSION
Pelvic lymph node dissection is a risk factor for inguinal hernia after radical resection of prostate cancer.

Pneumatosis intestinalis and pneumoperitoneum are not pathological entities in themselves, they are radiological signs that result from some underlying condition. In general, these are associated with serious intra-abdominal processes that result in emergency surgeries with bowel resections. Below, we present the case of an 80-year-old woman, diagnosed with stage IV breast cancer under treatment with fulvestrant and ribociclib, who was admitted to our center due to abdominal pain and vomiting. She was diagnosed with intestinal pneumatosis and pneumoperitoneum, so she underwent exploratory laparotomy for suspected intestinal ischemia. There was no evidence of intestinal necrosis or perforation, so resection was not performed. She progressed satisfactorily during hospitalization and in the tomographic control one month after discharge there was complete resolution of the condition. Although this condition has been described in relation to episodes of increased intra-abdominal pressure, such as emesis, it has also been described in patients with neoplasms, mainly of the digestive tract, either due to local damage or toxicity associated with chemotherapy. We found no reports in the literature of pneumatosis intestinalis linked to this antineoplastic medication in humans. Probably in our case the etiology was multifactorial. It is possible that ribociclib played a role, either through an indirect mechanism associated with vomiting and immunosuppression or directly on the enterocyte due to its non-specific cellular mechanism of action.

Ewing sarcoma (ES) and primitive neuroectodermal tumor (PNET) belong to the group of neoplasms called small round cell tumors. PNETs have been divided into central and peripheral. ES and peripheral PNETs arise from bones, soft tissues, or peripheral nerves. We present a case of hepatic ES/PNET in a healthy man that began four months before consultation with abdominal symptoms and weight loss. Upper gastrointestinal endoscopy and laboratory tests revealed no notable findings. The abdominal tomography revealed an enlarged liver due to a solid lesion that involved all its segments with intravenous contrast enhancement and large areas of necrosis. It compressed and displaced neighboring structures. Core needle biopsy of the liver lesion was performed: small round cell neoplasm. Immunohistochemistry revealed negativity for CD45, CKA1/A3, chromogranin, synaptophysin, and cytokeratins CK7 and CK20. Dim CD56 expression and CD99, FLI-1, and NKX2 positivity. He underwent chemotherapy treatment with carboplatin and etoposide for 6 cycles with clinical improvement and tolerance. Control images showed reduction of the mass with involvement of the right hepatic lobe, involvement of the inferior vena cava, infiltration of the right adrenal gland and upper pole of the right kidney. He was referred to hepatobiliary surgery for surgical resection of the residual lesion. The patient rejected the proposed surgical procedure. Our objective is to highlight the clinical and histological diagnostic challenge of this entity that requires ruling out other clinical entities.

BACKGROUND
For patients with stage III epithelial ovarian cancer, there are limited studies on the effects of postoperative adjuvant radiotherapy (RT). Here we assessed the therapeutic efficacy and toxicity of postoperative radiotherapy to the abdominal and pelvic lymphatic drainage area for stage III epithelial ovarian cancer patients, who had all received surgery and chemotherapy (CT).
METHODS
We retrospectively collected patients with stage III epithelial ovarian cancer after cytoreductive surgery (CRS) and full-course adjuvant CT. The chemoradiotherapy (CRT) group patients were treated with intensity modulated radiotherapy (IMRT) to the abdominal and pelvic lymphatic drainage area in our hospital between 2010 and 2020. A propensity score matching analysis was conducted to compare the results between the CRT and CT groups. Kaplan-Meier analysis estimated overall survival (OS), disease-free survival (DFS), and local control (LC) rates. The log-rank test determined the significance of prognostic factors.
RESULTS
A total of 132 patients with median follow-up of 73.9 months (9.1-137.7 months) were included (44 and 88 for the CRT and RT groups, retrospectively). The baseline characteristics of age, histology, level of CA12-5, surgical staging, residual tumour, courses of adjuvant CT, and courses to reduce CA12-5 to normal were all balanced. The median DFS time, 5-year OS, and local recurrence free survival (LRFS) were 100.0 months vs 25.9 months ( = .020), 69.2% vs 49.9% ( = .002), and 85.9% vs 50.5% ( = .020), respectively. The CRT group mainly presented with acute haematological toxicities, with no statistically significant difference compared with grade III intestinal adverse effects (3/44 vs 6/88, = .480).
CONCLUSION
This report demonstrates that long-term DFS could be achieved in stage III epithelial ovarian cancer patients treated with IMRT preventive radiation to the abdominal and pelvic lymphatic area. Compared with the CT group, DFS and OS were significantly prolonged and adverse effects were acceptable.
