Cholangiocarcinoma (CCA) has emerged as an intractable cancer with scanty therapeutic regimens. The aberrant activation of Yes-associated protein (YAP) and transcriptional co-activator with PDZ-binding motif (TAZ) are reported to be common in CCA patients. However, the underpinning mechanism remains poorly understood. Deubiquitinase (DUB) is regarded as a main orchestrator in maintaining protein homeostasis. Here, we identified Josephin domain-containing protein 2 (JOSD2) as an essential DUB of YAP/TAZ that sustained the protein level through cleavage of polyubiquitin chains in a deubiquitinase activity-dependent manner. The depletion of JOSD2 promoted YAP/TAZ proteasomal degradation and significantly impeded CCA proliferation

Objective:To investigate the clinicopathological features and immunohistochemical phenotypes of hybrid oncocytic/chromophobe tumor (HOCT) of the kidney and its associations with renal oncocytoma (RO) and eosinophilic chromophobe renal cell carcinoma (eChRCC).Methods:A total of 8 HOCT cases were collected from 2008 to 2019 at the Affiliated Hospital of Qingdao University (5 cases) and 971 Hospital of PLA Navy (3 cases), Qingdao, China for morphological studies, immunohistochemical staining and follow-up. The immunohistochemical results of HOCT were compared with those of 27 typical RO and 17 eChRCC.Results:Among the 8 patients, 3 were male and 5 were female. Their ages ranged from 39 to 75 years (median: 56 years). All cases were sporadic. Seven patients were asymptomatic and one suffered from lumbago. During a mean follow-up of 37 months in 7 patients, none of them developed tumor recurrence or metastasis. Seven cases were solitary and one was multiple. The tumor size ranged from 1.4 to 5.7 cm (mean, 3.6 cm). The cut surface of the tumors was dark red or yellowish. Histologically, the tumors were well-defined. Six cases were directly adjacent to the surrounding renal tissue, 2 cases had pseudocapsule, 3 cases showed entrapped renal tubules at the edge of tumor tissue, and one circumscribed with focal infiltrating borders. There were two types of histological morphology: one type (4 cases) was composed of mixed areas of otherwise typical RO and areas resembling chromophobe renal cell carcinoma; another type (4 cases) showed the morphological characteristics of both RO and eChRCC. Three second-type tumors showed nest-like, trabecular, and solid growth patterns with conspicuous edematous stroma. The cell border was conspicuous and the cytoplasm showed an eosinophilic appearance. The nuclei were small and round with clear perinuclear halo. One tumor showed a multi-nodular and solid growth pattern, and the cytoplasm was eosinophilic, hypochromatic or transparent. The nuclei were small and round, and some of them had obvious perinuclear halo. Immunohistochemically, the tumor cells in all 8 cases were positive for Ksp-cad but negative for vimentin. CD117 was diffusely positive in 6/8 cases. CK7 staining showed patchy positivity in 6/8 cases. S-100A1, cyclin D1 and claudin7 showed variable positivity in 4/8, 6/8 and 5/8 cases, respectively, but the range and intensity were narrower and weaker than those in RO and eChRCC.Conclusions:HOCT is a low-grade eosinophilic renal tumor with morphological characteristics resembling RO and eChRCC. The combined application of immunohistochemical stains of CK7, CD117, Ksp-cad, cyclin D1, claudin7 and S-100A1 may play an auxiliary role in the differentiation of the three tumors. HOCT has a good prognosis after surgical resection and can be regarded as a tumor with uncertain malignant potential.

Objective:Peripheral nerve invasion (PNI) is associated with local recurrence and poor prognosis in patients with advanced gastric cancer. A risk-assessment model based on preoperative indicators for predicting PNI of gastric cancer may help to formulate a more reasonable and accurate individualized diagnosis and treatment plan.Methods:Inclusion criteria: (1) electronic gastroscopy and enhanced CT examination of the upper abdomen were performed before surgery; (2) radical gastric cancer surgery (D2 lymph node dissection, R0 resection) was performed; (3) no distant metastasis was confirmed before and during operation; (4) postoperative pathology showed an advanced gastric cancer (T2-4aN0-3M0), and the clinical data was complete. Those who had other malignant tumors at the same time or in the past, and received neoadjuvant radiochemotherapy or immunotherapy before surgery were excluded. In this retrospective case-control study, 550 patients with advanced gastric cancer who underwent curative gastrectomy between September 2017 and June 2019 were selected from the Affiliated Hospital of Qingdao University for modeling and internal verification, including 262 (47.6%) PNI positive and 288 (52.4%) PNI negative patients. According to the same standard, clinical data of 50 patients with advanced gastric cancer who underwent radical surgery from July to November 2019 in Qingdao Municipal Hospital were selected for external verification of the model. There were no statistically significant differences between the clinical data of internal verification and external verification (all P>0.05). Univariate analysis and multivariate logistic regression analysis were used to determine the independent risk factors for PNI in advanced gastric cancer, and the clinical indicators with statistically significant difference were used to establish a preoperative nomogram model through R software. The Bootstrap method was applied as internal verification to show the robustness of the model. The discrimination of the nomogram was determined by calculating the average consistency index (C-index). The calibration curve was used to evaluate the consistency of the predicted results with the actual results. The Hosmer-Lemeshow test was used to examine the goodness of fit of the discriminant model. During external verification, the corresponding C-index index was also calculated. The area under ROC curve (AUC) was used to evaluate the predictive ability of the nomogram in the internal verification and external verification groups. Results:A total of 550 patients were identified in this study, 262 (47.6%) of which had PNI. Multivariate logistic regression analysis revealed that carcinoembryonic antigen level ≥ 5 μg/L (OR=5.870, 95% CI: 3.281-10.502, P<0.001), tumor length ≥5 cm (OR=5.539,95% CI: 3.165-9.694, P<0.001), mixed Lauren classification (OR=2.611, 95%CI: 1.272-5.360, P=0.009), cT3 stage (OR=13.053, 95% CI: 5.612-30.361, P<0.001) and the presence of lymph node metastasis (OR=4.826, 95% CI: 2.729-8.533, P<0.001) were significant independent risk factors of PNI in advanced gastric cancer (all P<0.05). Based on these results, diffused Lauren classification and cT4 stage were included to establish a predictive nomogram model. CEA ≥ 5 μg/L was for 68 points, tumor length ≥ 5 cm was for 67 points, mixed Lauren classification was for 21 points, diffused Lauren classification was for 38 points, cT3 stage was for 75 points, cT4 stage was for 100 points, and lymph node metastasis was for 62 points. Adding the scores of all risk factors was total score, and the probability corresponding to the total score was the probability that the model predicted PNI in advanced gastric cancer before surgery. The internal verification result revealed that the AUC of nomogram was 0.935, which was superior than that of any single variable, such as CEA, Lauren classification, cT stage, tumor length and lymph node metastasis (AUC: 0.731, 0.595, 0.838, 0.757 and 0.802, respectively). The external verification result revealed the AUC of nomogram was 0.828. The C-ndex was 0.931 after internal verification. External verification showed a C-index of 0.828 from the model. The calibration curve showed that the predictive results were good in accordance with the actual results ( P=0.415). Conclusion:A nomogram model constructed by CEA, tumor length, Lauren classification (mixed, diffuse), cT stage, and lymph node metastasis can predict the PNI of advanced gastric cancer before surgery.
