Urinary Dysfunction Assessment in Long-Term Survivors of Carcinoma Cervix Using LENT SOMA Scale: An Indian Study Addressing Quality of Life Issues

Effect and Mechanism of Curdione Combined with Gemcitabine on Migration and Invasion of Bladder Cancer

Bladder cancer (BCa), which usually occurs in bladder epithelial cells and is the fifth most common type of cancer in the world. he recurrence rate within 5 years after surgery is 0.8-45% of patients with early bladder cancer. Therefore, finding appropriate drug therapy for patients with bladder cancer can provide a reference for clinical treatment and play an important role in improving the prognosis of patients. In this study, CCK8 assay result showed that the inhibition of bladder cancer cell activity by Curdione and GEM increased with time and dose. Subsequently, CCK8, clone formation assay and Transwell result showed Curdione enhances GEM inhibition of bladder cancer cell activity, clonal formation and migration, these combine therapeutic schedule also could inhibited growth of in vivo xenograft tumors. The comprehensive database showed that CA2 is a potential target genes of Curdione, and Knockdown CA2 enhances GEM induced inhibition of cell proliferation and migration. Based on these advantages, Curdione may be a new type of action drug or adjunct for the treatment of bladder cancer.

[Clinical value of inflammatory biomarkers in predicting prognosis of patients with ureteral urothelial carcinoma]

OBJECTIVE

To evaluate the clinical value of inflammation-related markers in predicting the prognosis of patients with ureteral urothelial carcinoma.

METHODS

200 patients with ureteral urothelial carcinoma were randomly divided into two groups by split sample validation: modeling group and validation group. Paraffin embedded pathological specimens of the patients were reviewed. Immunohistochemical method was used to detect tumor-infiltrating neutrophil (TIN) (CD66b+), tumor-associated macrophage (TAM) (CD163+), lymphocyte (CD+, CD4+, CD8+) counts, peripheral blood neutrophil / lymphocyte ratio (NLR) and tumor tissue neutrophil/monocyte ratio (NMR). According to the results of pathological staging, the patients were divided into non-muscle-invasive and muscle-invasive ureteral urothelial carcinoma group. The resolution of the models was evaluated, and the prognostic nomogram models including only peripheral blood parameters and all parameters were established to compare the accuracy of the two models in predicting the prognosis of patients with urothelial carcinoma of the ureter.

RESULTS

The median follow-up time was 36 months, the progression-free survival was 40 months, and 42 cases (21.0%) showed tumor progression within 3 years. Tumor size, pathological stage and pathological grade were all single-factor variables predicting the first recurrence of ureteral urothelial carcinoma three years after operation. Tumor size, pathological stage, pathological grade, TIN, TAM, NLR and NMR were multi-factor variables predicting the first recurrence three years after operation. Among 104 cases of non-muscle-invasive ureteral urothelial carcinoma, 10 cases (9.6%) recurred for the first time 3 years after operation, 96 cases (33.3%) of muscle invasive ureteral urothelial carcinoma, and the diffe-rence between the two groups was statistically significant (χ2=15.53, P < 0.05). The predictive nomogram model of progression free survival was established. The concordance index of progression free survi-val was 0.722 (95%CI: 0.70-0.78) in non-muscle-invasion group, and 0.725 (95%CI: 0.71-0.79) in muscle-invasion group, which was in good agreement with the observed 3-year survival rate. The results of discrimination test showed that the concordance index of the whole parameter prediction model of ureteral urothelial carcinoma was 0.726, which was higher than that of peripheral blood parameters (consistency index 0.672). The immune microenvironment of ureteral urothelial carcinoma improved the prediction accuracy of the model.

CONCLUSION

The prognosis prediction model based on immune inflammation-related markers was established as a perfection and supplement for the existing pathological grading and staging system, providing a basis for accurate individualized treatment of patients with urete-ral urothelial carcinoma. The prognosis prediction model based on the relevant indicators of peripheral blood samples is established, which is easy to obtain specimens, and the detection method is simple and economical, which is more conducive to clinical application.

Morphological Characteristics and Clinical Significance of Different Types of Tumor Vessels in Patients with Stages I-IIA of Squamous Cervical Cancer

The determination of factors associated with progression of cervical cancer is important, both for a recurrence risk assessment and for determining optimal treatment tactics. Previously, we showed the prognostic value of different types of tumor microvessels (MVs) in gastric and breast cancer. The object of this research was to study the morphology and clinical significance of different tumor microvessels in early cervical cancer. A total of 65 archived paraffin blocks of patients with I-IIA stages of squamous cervical cancer were investigated. Samples were stained with Mayer hematoxylin and immunohistochemically using antibodies to CD34, podoplanin, HIF-1a, and Snail. The eight types of tumor MVs differed in morphology were identified. It was established that only the dilated capillaries (DСs) with weak expression of CD34, the contact type DCs, the capillaries in tumor solid component, and the lymphatic vessels in the lymphoid and polymorphic cell infiltrates of tumor stroma are associated with clinical and pathological characteristics of early cervical cancer. Preliminary results also suggest that a combination of fragmentation in tumor solid component and the contact type DCs may predict a recurrence of early cervical cancer. Given the small number of cervical cancer recurrences, the predictive significance of the described markers requires a more thorough examination.

Sexual Dysfunction in Carcinoma Cervix: Assessment in Post Treated Cases by LENTSOMA Scale

Treatment for cervical cancer consists of hysterectomy, radiotherapy, chemotherapy and targeted therapy in different combination based on stage at presentation. However, late consequences of such radical treatments are known but not many Indian studies have reported it. Quality of life and impact on sexual health has become an important issue in view of long survival of cervical cancer patients. LENTSOMA scale is one such scale validated for scoring radiotherapy related morbidity. However, there is need for a comprehensive scale covering all aspects of physical and psychological disruptions to provide complete recovery and rehabilitation. The study was prospective and patients who were treated for cervical cancer on follow up were included in this study. A total of 85 patients, who were treated with surgery, radiotherapy, chemotherapy alone or in combination, comprising of stage I to stage IV disease, participated in this study. Findings of this study showed that pain during intercourse and altered sexual life were reported by 32.9% and 25.9% patients respectively whereas 24.7% found it problematic and in 22.3% patients, alteration in interest in sex were reported. Vaginal stenosis was seen in 75.29% of patients after treatment with decreased frequency of intercourse after treatment was seen in 16.4 % of patients. Combination of surgery and radiotherapy in cervical cancer patients caused more sexual dysfunction and dissatisfaction, especially in lower age group. Treatment morbidity in term of sexual function was more with advanced stage disease and with the patients on longer follow up. Sexual function is an important aspect of quality of life but there is no single self-report measure in routine clinical follow up use which is brief, easy to complete and incorporates all (physical, psychological, emotional) aspects of sexual health for people affected by cancer.
