Vulvar cancer is a rare malignancy with an incidence of 2.5–4.4 per 100,000 persons per year, making it the fourth most common gynaecological malignancy (Huang et al., 2023). The most common type is vulvar squamous cell carcinoma (VSCC), followed by basal cell carcinoma, extramammary Paget's disease and vulvar melanoma. The median age at diagnosis is 69 years (Bogani et al., 2023). Although vulvar surgery and treatment has become more targeted and less radical over the decades, it may still cause scarring and mutilation of the external genitalia, and it also may affect various nerves and blood vessels involved in sexual, anal and/or urinary functions. Olesen et al. (2023) performed an integrated review to explore the impact of vulvar cancer on women's sexual health from a multidimensional perspective. They concluded that the sexual health of women with vulvar cancer was tabooed and stigmatised for patients and healthcare professionals. Consequently, women received sparse sexual guidance, felt isolated and had unmet needs. We would like to point out some suggestions to improve the paper. First, quantitative research is more convincing than qualitative research, as 28 articles were included, a meta-analysis should be performed to confirm the results. Second, the pathological classification of vulvar cancer differed from each study. Therefore, stratification analysis is required to identify the impact of vulvar cancer on women's sexual health and function. Third, most of the studies use non-validated tools such as clinical interviews or data taken from medical records. While these have made it possible to obtain qualitative insight into patients' experiences, there is less scope for distinguishing between areas and isolating the factors that impact on them. Last, the sample sizes of the included studies were small, which may decrease the statistical power. The importance of the role of psycho-oncologists in the treatment of vulvar cancer should be emphasised for proposing and offering psychological support and psychoeducational interventions. These kinds of interventions could be useful not only for sustaining women's sexual health and their emotional condition but also for supporting the familial network. Moreover, evaluation by a psychiatric specialist may be useful in order to provide possible psychopharmacological therapy in the presence of severe depressive–anxiety symptoms, analysing the risk factors and any pharmacological interactions with chemotherapy treatments. This may be useful in improving the detection and treatment of psychosexual and psychosocial distress. The ideal goal could be the integration of a psycho-oncologist and/or psychiatrist in the multidisciplinary team for the treatment of vulvar cancer with the aim of addressing both the physical and psychosocial needs of these women (Elit & Reade, 2015).

Background:To develop a novel highly accurate circulating tumor cell (CTC) identification method and to validate its application in cancer diagnostics and/or prognostics.Methods:We verified and validated the combined fluorescent probe staining protocol (combination of three fluorescent probes: Dil, Hoechst 33342, and PY) through CTC and non-CTC (white blood cell) morphological comparison of five tumor cell lines (THP-1, HEC, HEPG2, Eca-109, HeLa) in vitro and 32 patient tumor samples from the Shandong Cancer Hospital and Institute. Wright's Giemsa staining and cluster differentiation 45 (CD45) immunocytochemistry (ICC) staining were used as reference control methods. The association between the developed method and clinicopathology was also investigated.Results:We successfully developed and optimized the protocol, and validated the use of combined fluorescent probe staining for the identification of CTCs in the peripheral blood (PB) of tumor cell lines and tumor patients. Comparable CTC and non-CTC morphologies were observed for combined fluorescent probe staining and Giemsa staining methods in vitro. However, in vivo comparison between the three staining methods revealed that the identified CTCs differed in cell diameter and nucleo-cytoplasmic ratio. In addition, a higher CTC detection rate of 14/32, lower standard deviation (SD), and higher area under the receiver operating characteristic (ROC) curve (AUC) value of 0.844 were noted for combined fluorescence staining. Clinicopathological analysis revealed that CTCs were correlated with platelet levels (P=0.031), but not with age, gender, drinking history, or granule ratio.Conclusions:We developed a combined fluorescent probe staining method with higher CTC identification accuracy than Wright's Giemsa staining, and propose this technique as a novel clinical diagnostic/prognostic tool.
Background Circulating tumor cells (CTCs) are considered useful prognostic factors for various cancers, and in 2014, our research group conducted a comparative experiment of CTC detection in patients with renal cell cancer (RCC). However, the reason for the low detection rate of CTCs in cancer patients using the CellSearch® system is still unknown, although it has been hypothesized to be attributed to the likelihood that CTCs undergoing epithelial-mesenchymal transition (EMT) do not express the CTC biomarkers cytokeratin (CK)8/18/19 or epithelial cell adhesion molecule (EpCAM). The overall aim of the current study was to investigate the expression levels of CK8/18/19 and EpCAM in relation to the EMT biomarkers vimentin and E-cadherin in patients with RCC. Methods Patients with RCC who had undergone radical nephrectomy or partial resection between May 2014 and December 2014 were initially recruited. Results Among 34 RCC patients, nine co-expressed EpCAM and CK8/18/19 in primary tumor tissues. The CellSearch® results showed that CK8/18/19 was expressed in 5 of 6 patients (5/6) and EpCAM was expressed in 6 patients (6/6). However, the isolation by size of tumor cells (ISET) technique showed these were co-expressed in only four of the 10. The expression of CK8/18/19, EpCAM, vimentin, and E-cadherin was distributed unequally in different enumeration groups of CTCs (all P>0.05), and the positive expression of CK8/18/19 was correlated with neutrophil number and tumor size (P<0.05). The positive expression of vimentin was correlated with the Karnofsky Performance Status (KPS) score and clinical stage of renal cancer patients (P<0.05). Conclusions Our results indirectly proved the occurrence of EMT in the formation of CTCs by comparing and analyzing the expression of CK8/18/19 and EpCAM in renal cancer tissues and the detection results of CTCs.

Renal cell carcinoma is the second malignant tumors in the urinary system with high mortality and morbidity. Increasing evidence suggests that long non-coding RNAs (lncRNAs) play critical roles in tumor development and progression. In the current study, based on the publicly available data obtained from GEO and TCGA database, we identified five prognosis-related lncRNAs with the ability to predict the prognosis of patients with renal cell carcinoma. Among them, the uncharacterized and upregulated lncRNA RCAT1 (renal cancer-associated transcript 1) was identified as the key lncRNA. Our data further revealed that the expression of lncRNA RCAT1 was significantly upregulated in renal cell carcinoma tissues and cells. Gain-of-function and loss-of-function studies showed that lncRNA RCAT1 promoted cell proliferation, migration, and invasion in vitro and in vivo. Furthermore, we verified that lncRNA RCAT1 could abundantly sponge miR-214-5p, which served as a tumor suppressor in renal cell carcinoma. Significantly, miR-214-5p overexpression could attenuate the promotion of cell proliferation and metastasis induced by lncRNA RCAT1. Moreover, we found that E2F2 was a direct target of miR-214-5p, and lncRNA RCAT1 could protect E2F2 from miR-214-5p-mediated degradation. Taken together, our findings suggested that lncRNA RCAT1 could enhance the malignant phenotype of renal cell carcinoma cells by modulating miR‐214‐5p/E2F2 axis, and lncRNA RCAT1 might be a novel prognostic biomarker and a potential therapeutic target for renal cell carcinoma.

BACKGROUND/AIMS:Detection of circulating tumor cells (CTCs) in cancer patients has diagnostic and prognostic importance. However, the clinical implications of CTC detection in patients with renal cell carcinoma (RCC) are still unclear. In this study, we investigated the clinical significance of CTCs using two detection systems, the CellSearch system (CSS) and isolation by size of epithelial tumor cells (ISET), among RCC patients.METHODS:We recruited 36 RCC patients and 22 healthy volunteers as controls. Blood was drawn before treatment. Samples were analyzed using the CSS and ISET. We prospectively followed the RCC patients to determine overall and progression-free survival.RESULTS:We did not detect CTCs in the control group using either the CSS or ISET. CTCs were detected in 7/36 patients (19.4%) using the CSS and in 13/36 patients (36.1%) using ISET, while circulating microemboli (CTMs) were detected in three patients (8.3%). The presence of ISET-detected CTCs correlated with clinical tumor node metastasis (TNM) stages, while the CSS-detected CTCs did not. After 36 months (median), CTCs detected by both methods failed to correlate with overall and progression-free survival among RCC patients.CONCLUSION:We discovered that ISET is more suitable than the CSS for detecting CTCs in RCC patients. The presence of CTCs/CTMs in RCC patients correlated with higher TNM stages, suggesting that the presence of CTCs could be a prognostic marker in RCC patients.
Detection of circulating tumor cells (CTCs) has been made to develop reliable assays for early diagnosis of various cancers. Overexpression of survivin in cancer cells is strongly associated with tumor progression. Although upregulation of survivin is observed in various tumors, its expression profile in the peripheral blood of prostate cancer (PCa) patients has not yet been investigated. In this study, we validated the application of survivin as the tumor marker to detect CTC and assessed its utility for diagnosis of PCa distant metastasis. Immunohistochemistry and quantitative real-time PCR (QRT-PCR) were performed to confirm the levels of surviving expression in PCa tissues. In addition, CTC values in 3 mL of peripheral blood from PCa patients, benign prostate hyperplasia (BPH) patients, and normal controls were also measured by the survivin-targeted PCR. Our results showed that surviving was overexpressed in PCa tissues. The median levels of blood surviving mRNA of PCa patients, BPH patients, and normal controls were 5.67 (range from 0 to 12.46), 2.24 (range from 0 to 6.55), and 1.85 (range from 0 to 3.82), respectively. The levels of survivin are positively associated with PCa distant metastasis. Our results concluded that quantitation of CTCs through survivin-PCR could be a promising marker for diagnosis of PCa metastasis.

The specificity of circulating tumor cell (CTC) such as epithelial-mesenchymal transition,fusion of bone marrow-derived cells,resistance anoikis determines the necessity of cell cultivating.The produced cell lines can provide good material basis for further research of malignant tumor metastasis,also provide individualized targeted therapy for patients with a new direction.
Combination chemotherapy is emerging in the management of advanced penile cancer. However, evidence-based chemotherapeutic regimens in the current guidelines are lacking.

BACKGROUND:Identifying novel tumor biomarkers to develop more effective diagnostic and therapeutic strategies for patients with ACC is urgently needed. The aim of the study was to compare the proteomic profiles between adrenocortical carcinomas (ACC) and normal adrenocortical tissues in order to identify novel potential biomarkers for ACC.METHODS:The protein samples from 12 ACC tissues and their paired adjacent normal adrenocortical tissues were profiled with two-dimensional electrophoresis; and differentially expressed proteins were identified by mass spectrometry. Expression patterns of three differently expressed proteins calreticulin, prohibitin and HSP60 in ACC, adrenocortical adenomas (ACA) and normal adrenocortical tissues were further validated by immunohistochemistry.RESULTS:In our proteomic study, we identified 20 up-regulated and 9 down-regulated proteins in ACC tissues compared with paired normal controls. Most of the up-regulated proteins were focused in protein binding and oxidoreductase activity in Gene Ontology (GO) molecular function classification. By immunohistochemistry, two biomarkers calreticulin and prohibitin were validated to be overexpressed in ACC compared with adrenocortical adenomas (ACA) and normal tissues, but also calreticulin overexpression was significantly associated with tumor stages of ACC.CONCLUSION:For the first time, calreticulin and prohibitin were identified to be novel candidate biomarkers for ACC, and their roles during ACC carcinogenesis and clinical significance deserves further investigation.VIRTUAL SLIDES:The virtual slides for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/1897372598927465.
OBJECTIVE: To compare the proteomic profiling of renal clear cell carcinoma (RCC) and paratumorous tissues, in order to identify novel tumor markers. METHODS: Protein samples from 10 RCC tissues and their paired paratumor tissues were extracted, and isolated by two-dimensional electrophoresis. Differently expressed protein spots were identified by mass spectrometry. RESULTS: About 20 up-regulated and 10 down-regulated proteins in RCC tissues. Most of the up-regulated proteins were involved in response to hypoxia, anti-apoptosis and Glycolysis, Regulation of actin cytoskeleton and PPAR cancer-related pathway. CONCLUSION: The differently identified proteins in this study were novel candidate biomarkers for RCC, and its clinical significance deserves further investigation.
