AbstractObjectiveThe aim of this study was to evaluate the expression of Angiopoietin-1 (Ang-1), Angiopoietin-2 (Ang-2) and vascular endothelial growth factor (VEGF) in cervical cancer and its clinical significance.MethodsImmunohistochemical assay was used to examine the expression of Ang-1/2 and VEGF in tumor tissue from 56 cervical squamous cell carcinoma patients treated with operation only (SCC-O group), as well as 51 subjects with cervical squamous cell carcinoma treated with neoadjuvant radiotherapy (SCC-RCO group, n=28) or neoadjuvant chemotherapy (SCC-CO group, n=23). Both microvessel density (MVD) and lymphatic vessel density (LVD) were examined in the three groups through detection of CD34 and D2-40 expression in respective tissue samples.ResultsWith the progression of cervical cancer, the positive expression scores of Ang-2 and VEGF were significantly increased (p<0.05). Compared with surgical intervention, neoadjuvant chemoradiotherapy significantly reduced the positive expression scores of Ang-1, Ang-2, and VEGF in cervical cancer tissues (p<0.05). The MVD values of the SCC-CO and SCC-RO groups were significantly reduced as compared to the SCC-O group (p<0.05). Similarly, the LVD values of the SCC-CO and SCC-RO groups were also significantly reduced when compared to those of the SCC-O group (p<0.05). However, LVD values of the SCC-CO and SCC-RO groups were not statistical different (p>0.05).ConclusionAng-1, Ang-2 and VEGF may play an important role in the development of cervical cancer. Mutual synergism of Ang-2 and VEGF demonstrated a close relationship with the generation of cervical blood and lymphatic vessels. Cervical cancer radiotherapy and chemotherapy could significantly inhibit the formation of blood vessels and lymphatic vessels in tumor tissue.

Acetyl Coenzyme A Synthase

Cervical squamous cell carcinoma (CESC) is one of the most common malignant tumors in women worldwide with a low survival rate. Acetyl coenzyme A synthase 2 (ACSS2) is a conserved nucleosidase that converts acetate to acetyl-CoA for energy production. Our research intended to identify the correlations of ACSS2 with clinical prognosis and tumor immune infiltration in CESC. ACSS2 is highly expressed in many tumors and is involved in the progression and metastasis of these tumors. However, it is not clear how ACSS2 affects CESC progression and immune infiltration. Analysis of the cBioPortal, GEPIA2, UALCAN, and TCGA databases showed that ACSS2 transcript levels were significantly upregulated in multiple cancer types including CESC. Quantitative RT-PCR analysis confirmed that ACSS2 expression was significantly upregulated in human cervical cancer cells. Here, we performed tissue microarray analysis of paraffin-embedded tissues from 240 cervical cancer patients recorded at FIGO/TNM cancer staging. The results showed that ACSS2 and PDL1 were highly expressed in human CESC tissues, and its expression was associated with the clinical characteristics of CESC patients. TIMER database analysis showed that ACSS2 expression in CESC was associated with tumor infiltration of B cells, CD4+ and CD8+ T cells, and cancer-associated fibroblasts (CAF). Kaplan–Meier survival curve analysis showed that CESC with high ACSS2 expression was associated with shorter overall survival. Collectively, our findings establish ACSS2 as a potential diagnostic and prognostic biomarker for CESC.

Abstract Background: Combined cervical cancer and pelvic organ prolapse (POP) is extremely uncommon and there is no standard treatment guideline for the complex comorbidity. We attempted to provide a treatment strategy and explore possible reasons for the comorbidities.Case presentation: We presented a 62-year-old patient seeking treatment for postmenopausal tissue prolapse and leakage of urine. Physical examination revealed procidentia with a 2.5 cm papillary and erosive lesion that was pathologically confirmed as cervical squamous cell carcinoma in stage Ib2. Clinical diagnosis included cervical squamous cell carcinoma in stage Ib2, prolapse of the anterior and posterior walls of the vagina and uterine, stress urinary incontinence (SUI). Then she was performed radical surgery for cervical cancer and tension-free vaginal tape-obturator (TVT-O). The urine function was good after operation. The surgery solved two diseases, which improved the quality of life (QOL) of patient and radically cured cervical malignancies at the same time.Conclusions: Surgical-based treatment seems to be more suitable that can cure the two diseases and improve the QOL. We should pay attention to the potential high incidence of HPV infection and HPV-related cervical cancer so that we should not ignore the screening for cervical cancer in the prolapse group and initiate surgery treatment strategies of cervical cancer or pre-cancerous lesions as early as possible to reach an optimal outcome of patient.

Objective To describe a case of radiation-induced uterine carcinosarcoma 6 years after a cervical squamous cell carcinoma treatment, which imposed some diagnostic and management challenges. Case Report A 57-year-old woman with a history of pelvic chemoradiotherapy ∼ 6.5 years before the event described in this study, following an International Federation of Gynecology and Obstetrics (FIGO) stage IIB cervical cancer, presented with a cervical mass, involving the uterine cavity, the cervical canal and the upper two thirds of the vagina. The biopsy showed a poorly differentiated carcinoma, and a positron emission tomography (PET) scan excluded distant metastasis, although it was unable to define the origin of the tumor as either a new primary malignancy of the endometrium/cervix or as a cervical recurrence. Surgical staging procedure was performed, and the diagnosis was endometrial carcinosarcoma, FIGO stage IIB. The patient was not able to complete the adjuvant therapy, and the progression of the disease was remarkable. Conclusion The present case highlights one of the less common but more serious consequences of radiotherapy for cervical cancer, which has an increasing incidence in younger women, raising concerns about the long-term consequences of its management.
