The assessment of spectral Doppler parameters in uterine arteries of patients with locally advanced squamous cell cervical cancer

Objectives: Evaluate spectral Doppler parameters peak systolic velocity (PSV), end diastolic velocity (EDV), resistance index (RI) and pulsatility index (PI) in infiltrated and non-infiltrated uterine arteries of patients with locally advanced (stages II B, III B) squamous cell cervical cancer and their changes during treatment.  Material and methods: the study group included 36 patients aged 35–78 years old. At diagnosis, PSV, EDV, RI and PI in uterine arteries were examined and compared with MRI findings. All patients underwent transvaginal doppler ultrasonography prior to the treatment, after external beam radiation therapy and six weeks after the last application of brachytherapy.  Results: The median PSV value in the first examination was higher in infiltrated uterine arteries than compared to non-infiltrated ones (p = 0.001). The PSV values for all vessels decreased between the first and the third observation (p < 0.001). There was a significant difference in PI values between infiltrated and non-infiltrated uterine arteries between the first and the third examination (p = 0.027).  Conclusions: In patients with locally advanced cervical cancer of uterine arteries, assessment of PSV but not EDV, RI or PI can be helpful in differentiating infiltrated from non-infiltrated vessels. In this group of patients, radiotherapy decreases PSV, but not EDV, RI or PI values in uterine arteries. An observation conducted from the onset of radiotherapy to end of the follow-up in uterine arteries reveals that PI, but not RI, PSV or EDV, is different in infiltrated and non-infiltrated vessels

Prospective analysis of the impact of adjuvant treatment with external beam radiation therapy and vaginal brachytherapy on health-related quality of life in patients with early-stage endometrioid endometrial carcinoma

Objectives: Our study evaluates the impact of adjuvant treatment with external beam radiotherapy (EBRT) combined with vaginal high dose rate brachytherapy (HDR BT) on health related quality of life (HRQL) in patients with early stage endometrioid endometrial carcinoma. Material and methods: From March 2019 to February 2021, 60 patients were enrolled with early stage endometrioid endometrial carcinoma, and qualified to adjuvant treatment after hysterectomy. HRQL was assessed using the EORTC QLQ-C30 questionnaire, with the endometrial cancer-specific HRQL module EORTC QLQ-EN24. Questionnaires were completed in four timepoints during adjuvant radiotherapy. Results: A significant decrease in mean global health status / quality of life (p < 0.001) and role functioning (p = 0.028) was noted, as assessed in EORTC QLQ-C30 scale. Among the EORTC QLQ-C30 symptoms scales, significant differences were noted in the fatigue scale (p = 0.003), pain scale (p = 0.001), constipation scale (p < 0.001) and diarrhea scale (p < 0.001) over time. The EORTC QRQ-EN24 analysis showed significant deterioration in the urological symptoms scale (p < 0.001), gastrointestinal symptoms scale (p < 0.001) and in the mean pain in back and pelvis scale (p = 0.003). Conclusions: Adjuvant radiotherapy in patients with early-stage endometrioid endometrial cancer after hysterectomy is associated with worse quality of life, especially due to the toxicity of the treatment in relation to the gastrointestinal tract and urinary system

The impact of adjuvant treatment with external beam radiotherapy and vaginal brachytherapy on health-related quality of life in patients with early-stage endometrioid endometrial carcinoma — initial results of a prospective study

Objectives: Our study evaluates the impact of adjuvant treatment with external beam radiotherapy (EBRT) combined with vaginal high-dose-rate brachytherapy (HDR BT) on health-related quality of life (HRQL) in patients with early-stage endometrioid endometrial carcinoma. Material and methods: We assessed HRQL of patients based on the EORTC QLQ-C30 questionnaire, with endometrial cancer specific HRQL module — EORTC QLQ-EN24. From March 2019 to April 2020 we enrolled 20 patients with early-stage endometrioid endometrial carcinoma, qualified for adjuvant treatment after hysterectomy. We compared the scores measured with the questionnaires at the beginning and at the end of the treatment. Results: There was a statistically significant decrease in the mean of global health status/quality of life assessed according to the EORTC QLQ-C30 scale, from 62.25 ± 13.12 at the beginning of the adjuvant radiotherapy to 55.85 ± 14.68 at the end of the treatment (p = 0.047). The mean appetite loss score was higher at the onset of the treatment as compared to its value after EBRT, 19.9 ± 27.33 vs 11.6 ± 19.52 (p = 0.043). Similarly to the mean constipation score, which was 29.85 ± 30.40 vs 11.6 ± 19.52 (p = 0.013). The mean diarrhoea symptom scale increased from 16.55 ± 20.16 to 56.75 ± 36.10 (p = 0.001). In the EORTC QLQ-EN24 scales, gastrointestinal symptoms scores were higher at the end of the treatment, (with the mean of 26.45 ± 22.76) as compared to 14.30 ± 16.52 at the beginning of EBRT (p = 0.003). Conclusions: Patients who receive adjuvant radiotherapy have decreased quality of life during the treatment reporting more serious gastrointestinal symptoms. The potential risk of treatment-related toxicity should be taken into account during the treatment planning process in order to minimize the deterioration of HRQL

Assessment of cervical volume and spectral Doppler parameters in tumour dominant vessel of patients with locally advanced squamous cell cervical carcinoma

We evaluated cervical volume and spectral Doppler parameters: peak systolic velocity (PSV), resistance index (RI) and pulsatility index (PI) in the tumour dominant vessel of 50 patients with cervical squamous cell carcinoma (SCC) staged IIB and IIIB and their changes during treatment. The patients underwent transvaginal Doppler ultrasonography prior to treatment, after external beam radiation therapy (EBRT) and 6 weeks after brachytherapy. Radiotherapy decreased cervical volume and PSV values of the tumour dominant vessel. The PSV values before EBRT in G1 + G2 tumours were higher than in G3 tumours. No correlations between cervical volume, PSV, RI and PI values with disease-free survival (DFS) and overall survival (OS) were found. We concluded, that sonographic assessment of changes in cervical volume of patients with locally advanced cervical SCC during treatment did not allow to predict treatment results. Spectral Doppler parameters PSV, RI and PI of tumour dominant vessel did not predict prognosis for these patients.Impact Statement What is already known on this subject? Transvaginal Doppler sonography is considered as a useful diagnostic method in patients with cervical carcinoma. However, despite numerous studies, the value of spectral Doppler parameters in tumour dominant vessel and cervical volume of patients with locally advanced cervical SCC is still not well defined. What the results of this study add? In our prospective study, we found that sonographic assessment of changes in cervical volume of patients with locally advanced cervical SCC during treatment did not allow to predict treatment results and spectral Doppler parameters of tumour dominant vessel did not predict prognosis for these patients. What the implications are of these findings for clinical practice and/or further research? Our study underlines the limited value of spectral Doppler technique in patients with cervical carcinoma. Further research should be focussed on identifying and validating novel prognostic and predictive factors

Clinical significance of CD34, podoplanin and Ki-67 expression in patients with locally advanced squamous cell cervical carcinoma

The aim of the study was to assess immunohistochemical CD34, podoplanin and Ki-67 expression in cervical tumour of patients with cervical squamous cell carcinoma (SCC) staged IIB and IIIB, a relationship with selected clinical and histological parameters and its prognostic significance. This prospective study included 52 patients. Microvessel density (MVD) by CD34, lymphatic vessel density (LVD) by podoplanin and the Ki-67 index in specimens from paraffin blocks with cervical SCC tissues were examined. The relationship between these data and selected clinical and histological parameters was analysed. Positive correlation of MVD and the Ki-67 index was observed. No correlation was observed for MVD, LVD and the Ki-67 index in the tumour with staging, grading, length of treatment and squamous cell carcinoma antigen (SCC-Ag) concentration before and after treatment. The expression of MVD, LVD and the Ki-67 index in cervical SCC did not contribute to the risk of relapse and cancer-related death. No relationship was found for MVD, LVD and the Ki-67 index in cervical tumour of patients with locally advanced cervical SCC with staging, grading and serum SCC-Ag level. MVD, LVD and the Ki-67 index in the tumour did not contribute to the risk of relapse or cervical SCC-related death.Impact Statement What is already known on this subject? In many patients, invasive cervical squamous cell carcinoma (SCC) is diagnosed in a locally advanced stage, when the prognosis depends on many well-known factors connected with tumour biology, staging and general condition of the patient. Despite numerous studies, the value of immunohistochemical CD34, podoplanin and Ki-67 expression in cervical tumour of these patients is still not well defined. What do the results of this study add? In our prospective study, no relationship for microvessel density (MVD), lymphatic vessel density (LVD) and the Ki-67 index in cervical tumour of patients with locally advanced cervical SCC with staging, grading and serum squamous cell carcinoma antigen (SCC-Ag) level was found. Additionally, MVD, LVD and the Ki-67 index in the tumour did not contribute to the risk of relapse or cervical SCC-related death. What are the implications of these findings for clinical practice and/or further research? Our study underlines the limited value of immunohistochemical CD34, podoplanin and Ki-67 expression in cervical tumour of patients with locally advanced cervical SCC. Further research should be focussed on identifying and validating novel prognostic and predictive factors
