Sentinel node mapping in high-intermediate and high-risk endometrial cancer: Analysis of 5-year oncologic outcomes

To assess 5-year oncologic outcomes of apparent early-stage high-intermediate and high-risk endometrial cancer undergoing sentinel node mapping versus systematic lymphadenectomy. This is a multi-institutional retrospective, propensity-matched study evaluating data of high-intermediate and high-risk endometrial cancer (according to ESGO/ESTRO/ESP guidelines) undergoing sentinel node mapping versus systematic pelvic lymphadenectomy (with and without para-aortic lymphadenectomy). Survival outcomes were assessed using Kaplan-Meier and Cox proportional hazard methods. Overall, the charts of 242 patients with high-intermediate and high-risk endometrial cancer were retrieved. Data on 73 (30.1%) patients undergoing hysterectomy plus sentinel node mapping were analyzed. Forty-two (57.5%) and 31 (42.5%) patients were classified in the high-intermediate and high-risk groups, respectively. Unilateral sentinel node mapping was achieved in all patients. Bilateral mapping was achieved in 67 (91.7%) patients. Three (4.1%) patients had site-specific lymphadenectomy (two pelvic areas only and one pelvic plus para-aortic area), while adjunctive nodal dissection was omitted in the hemipelvis of the other three (4.1%) patients. Sentinel nodes were detected in the para-aortic area in eight (10.9%) patients. Twenty-four (32.8%) patients were diagnosed with nodal disease. A propensity-score matching was used to compare the aforementioned group of patients undergoing sentinel node mapping with a group of patients undergoing lymphadenectomy. Seventy patient pairs were selected (70 having sentinel node mapping vs. 70 having lymphadenectomy). Patients undergoing sentinel node mapping experienced similar 5-year disease-free survival (HR: 1.233; 95%CI: 0.6217 to 2.444; p = 0.547, log-rank test) and 5-year overall survival (HR: 1.505; 95%CI: 0.6752 to 3.355; p = 0.256, log-rank test) than patients undergoing lymphadenectomy. Sentinel node mapping does not negatively impact 5-year outcomes of high-intermediate and high-risk endometrial cancer. Further prospective studies are warranted.

Age-Adjusted Charlson Comorbidity Index Predicts Survival in Endometrial Cancer Patients

<b><i>Objective:</i></b> Comorbidity scores are increasingly used to reduce potential confounding in oncologic research. This is of paramount importance in endometrial cancer (EC) since it is characterized by quite indolent behavior. Here, we aim to evaluate the impact of various comorbidities and concurrent medications used on survival outcomes, adopting the age-adjusted Charlson comorbidity index (A-CCI). <b><i>Design:</i></b> This is an observational study. Charts of 257 EC patients were retrieved. <b><i>Methods:</i></b> We retrospectively evaluated data of patients who underwent surgical treatment for EC. A-CCI was calculated by summing the weighted comorbidities and age of each patient. A binomial value was assigned to different comorbidities and different drugs. Oncologic outcomes were evaluated using Cox proportional hazard models adjusted for age. <b><i>Results:</i></b> A-CCI ≥3 correlated with more aggressive tumor features (47.6% vs. 26.8%, <i>p</i> = 0.001), higher risk of recurrence (29.7% vs. 11.6%, <i>p</i> = 0.001), death (20.7% vs. 7.1%, <i>p</i> = 0.002), and death due to disease (16.6% vs. 6.3%, <i>p</i> = 0.012). Considering comorbidities and drugs at parsimonious multivariable analysis model: cardiac disease, liver disease, and proton pump inhibitors (PPIs) use were independent predictors of disease-free survival. Cardiac disease, autoimmune disease, and PPIs use were independent predictors of overall survival. Diabetes was the only independent predictor for cause-specific survival. <b><i>Limitations:</i></b> The major limitation of the present study is its retrospective nature and the relatively small sample size that limit the possibility to have firm conclusions. <b><i>Conclusion:</i></b> Patients with EC are characterized by a high burden of comorbidities. Comorbidities are associated directly with survival outcomes. Further attention is needed to improve the active management of comorbidities soon after EC treatments. Interventional studies are needed to improve patients’ outcomes.

Intraperitoneal Chemotherapy: A Strategy for the Treatment of Refractory Ascites in Recurrent Endometrial Cancer Patients – Three Case Reports and Review of the Literature

<b><i>Background:</i></b> Endometrial cancer currently represents the most frequent gynecologic malignancy in Western countries, and the seventh most common cancer in women. For advanced-stage disease, the recurrence risk is high, and the site of the relapse is heterogeneous with localized or spread peritoneal disease. There are few therapeutic strategies, and the quality of life is poor. <b><i>Cases Presentation:</i></b> We present 3 cases of peritoneal-spread recurrences of endometrial cancer in patients with advanced stage at diagnosis. The patients had been subjected to multiple lines of chemotherapy including re-challenging with platinum regimens, pegylated liposomal doxorubicin, and taxane, with progression of disease. These patients came to us with abdominal distension, dyspnea, elevated CA 125, and presence of ascites. After paracentesis with a single administration of intraperitoneal chemotherapy based on carboplatin, all 3 patients showed improvement in their quality of life and breathing as well as reduction of fatigue and anorexia. No complications occurred. <b><i>Conclusion:</i></b> Although only 3 cases are reported, the exceptional results and the absence of side effects observed strongly warrant future trials to investigate the role intraperitoneal chemotherapy can have both as palliative treatment of refractory ascites and as salvage therapy in advanced endometrial cancer.

A pilot multimodal study of cervical cancer: Raman spectroscopy as a molecular fingerprint tool

Cervical cancer remains a significant global health burden, highlighting the need for more effective tools for early detection and tissue characterization. In this study, we propose a multimodal strategy that combines Raman spectroscopy, Atomic Force Microscopy (AFM), and Scanning Electron Microscopy (SEM) to investigate the molecular and morphological features of cervical squamous cell carcinoma (SCC). Raman spectroscopy was used to analyze biochemical signatures across different tissue regions tumor, necrotic, stromal, and glandular within the 813–1668 cm -1 range, identifying distinct molecular profiles between malignant and healthy areas. Specific vibrational peaks associated with DNA, proteins, and lipids were examined to track molecular changes related to tumor progression. AFM enabled nanoscale mapping of surface morphology, revealing structural irregularities associated with malignancy, while SEM provided detailed imaging of cellular and extracellular architecture, enhancing the visualization of cancer-induced morphological alterations. Although Raman spectroscopy has been studied for decades in cancer research, it has not yet replaced Pap smears and biopsies in clinical practice due to challenges in standardization, reproducibility, and clinical validation. This pilot study aims to serve as a stepping stone toward that goal, providing proof-of-concept data that may support the gradual translation of Raman spectroscopy into clinically relevant diagnostic workflows and underscores the potential of the technique, supported by complementary high-resolution imaging techniques, in the characterization of cervical cancer tissues. The integration of Raman, AFM, and SEM was used here as a pilot approach on paraffin-embedded samples, with AFM and SEM providing supportive morphological information while the long-term aim is to transfer Raman spectroscopy to fresh, untreated tissues, where its non-destructive and label-free nature could enable minimally invasive diagnostic applications.

Fertility-sparing surgery for women with stage I cervical cancer of 4 cm or larger: a systematic review

To investigate current evidence on oncological, fertility and obstetric outcomes of patients with stage I cervical cancer of 4 cm or larger undergoing fertility-sparing surgery (FSS). Systematic review of studies including women affected by stage I cervical cancer ≥4 cm who underwent FSS. Main outcome measures: disease-free survival (DFS), overall survival (OS), pregnancy rate, live birth rate, premature delivery rate. Fifteen studies met all eligibility criteria for this systematic review, involving 48 patients affected by cervical cancer ≥4 cm who completed FSS. Three patients (6.3%) experienced a recurrence and one of them (2.1%) died of disease. The 5-year DFS rate was 92.4%. The 5-year OS rate was 97.6%. A significantly shorter 5-year DFS was reported for high-risk patients (G3, non-squamous histotype, diameter ≥5 cm) compared with low-risk (74.7% vs. 100%; log-rank test, p=0.024). Data about fertility outcomes were available for 12 patients. Five patients out of 12 (41.7%) attempted to conceive with an estimated pregnancy rate of 80%, a live birth rate of 83.3% and a premature delivery rate of 20%. Women with high tumor grade, aggressive histology and tumor size ≥5 cm have a higher risk of recurrence. Oncologic outcomes are encouraging among low-risk patients; however, the lack of high-quality studies makes it difficult to draw any firm conclusions. Prospective multicentric clinical trials with a proper selection of inclusion/exclusion criteria should be conducted in women with low-risk factors, strong desire to preserve their fertility and high likelihood to conceive.

Systematic lymph node dissection during interval debulking surgery for advanced epithelial ovarian cancer: a systematic review and meta-analysis

To evaluate the efficacy and safety of systematic lymph node dissection (SyLND) at the time of interval debulking surgery (IDS) for advanced epithelial ovarian cancer (AEOC). Systematic literature review of studies including AEOC patients undergoing SyLND versus selective lymph node dissection (SeLND) or no lymph node dissection (NoLND) after neoadjuvant chemotherapy (NACT). Primary endpoints included progression-free survival (PFS) and overall survival (OS). Secondary endpoints included severe postoperative complications, lymphocele, lymphedema, blood loss, blood transfusions, operative time, and hospital stay. Nine retrospective studies met the eligibility criteria, involving a total of 1,660 patients: 827 (49.8%) SyLND, 490 (29.5%) SeLND, and 343 (20.7%) NoLND. The pooled estimated hazard ratios (HR) for PFS and OS were, respectively, 0.88 (95% confidence interval [CI]=0.65-1.20; p=0.43) and 0.80 (95% CI=0.50-1.30; p=0.37). The pooled estimated odds ratios (ORs) for severe postoperative complications, lymphocele, lymphedema, and blood transfusions were, respectively, 1.83 (95% CI=1.19-2.82; p=0.006), 3.38 (95% CI=1.71-6.70; p<0.001), 7.23 (95% CI=3.40-15.36; p<0.0001), and 1.22 (95% CI=0.50-2.96; p=0.67). Despite the heterogeneity in the study designs, SyLND after NACT failed to demonstrate a significant improvement in PFS and OS and resulted in a higher risk of severe postoperative complications.

The Role of 2D/3D Ultrasound to Assess the Response to Neoadjuvant Chemotherapy in Locally Advanced Cervical Cancer

&lt;b&gt;&lt;i&gt;Introduction:&lt;/i&gt;&lt;/b&gt; Different imaging techniques were introduced to improve preoperative clinical staging of locally advanced cervical cancer (LACC) with transvaginal ultrasound (TV-US) or transrectal ultrasound (TR-US) representing a promising staging technique in the evaluation of the local extension of the disease for invasive tumors. The aim of this study was to evaluate the response to neoadjuvant chemotherapy (NACT) in LACC by 2D/3D ultrasound examination. &lt;b&gt;&lt;i&gt;Materials and Methods:&lt;/i&gt;&lt;/b&gt; We prospectively enrolled patients affected by histologically and clinically confirmed LACC. All patients were scheduled for 3 cycles of platinum-based NACT followed by radical surgery. The ultrasound examination was performed at every cycle and within 10 days before surgery. The parameters evaluated were: the volume (automatically computed by the VOCAL software) and the mass vascularization. &lt;b&gt;&lt;i&gt;Results:&lt;/i&gt;&lt;/b&gt; From March 2010 to March 2019, 157 women were recruited. Among these patients, 12 of them were excluded: 6 for the presence of distant metastases, 4 for rare histology, and 2 for severe comorbidities not allowing the protocol treatment. Seventeen patients after NACT were excluded because they were not amenable to radical surgery. Thus, 128 were considered for the final analysis of whom 106 (83%) were considered responders to NACT by histology. The sensibility and specificity of ultrasound with regard to the response to chemotherapy compared to histological specimen were 94 and 82%, respectively, with an accuracy of 92%. The positive predictive value and negative predictive value were 96 and 75%, respectively. Finally, we found that nonetheless there was a trend towards a continuous response to chemotherapy among patients who were considered responders to NACT at pathological examination; the major volume and vascularization index (VI) reduction were observed during the first 2 cycles (74, 71% and 47, 63%, respectively). On the contrary, non-responders showed an initial reduction of the VI (4.86 consisting of 33%, 95% CI 0.79–8.92, &lt;i&gt;p&lt;/i&gt; = 0.013), but no significant modification in tumour volume along NACT. &lt;b&gt;&lt;i&gt;Conclusion:&lt;/i&gt;&lt;/b&gt; 2D/3D ultrasound is useful in assessing early response to NACT in patients with LACC.

Evaluation of Parametrial Status in Locally Advanced Cervical Cancer Patients after Neoadjuvant Chemotherapy: A Prospective Study on Diagnostic Accuracy of Three-Dimensional Transvaginal Ultrasound

&lt;b&gt;&lt;i&gt;Objectives:&lt;/i&gt;&lt;/b&gt; To analyze the diagnostic accuracy of two-dimensional (2D) and three-dimensional transvaginal ultrasound (3D TV-US) for evaluation of parametrial status in locally advanced cervical cancer patients after neoadjuvant chemotherapy (NACT), using histology as the gold standard. &lt;b&gt;&lt;i&gt;Methods:&lt;/i&gt;&lt;/b&gt; Consecutive patients with histologically confirmed cervical cancer were staged according to FIGO (International Federation of Gynaecology and Obstetrics) criteria. All IB2-IIIB FIGO stage patients were examined by 2D and 3D TV-US and magnetic resonance imaging (MRI) at the diagnosis time (T0) and after NACT. At T0, the US evaluation of parametrial involvement was compared to MRI before treatment. The results of US and MRI examinations of parametrial status after NACT were compared with the histological specimen. &lt;b&gt;&lt;i&gt;Results:&lt;/i&gt;&lt;/b&gt; We enroled 51 consecutive patients in the study. Before chemotherapy, clinical examination under anaesthesia identified parametrial involvement in 48 patients, ultrasonography in 46 patients, and MRI in 49 patients. The agreement between US and MRI was 94%. The sensitivity of US for parametrial status was 93.8%, with a positive predictive value of 97.8%, using MRI as the standard. The correlation between US and MRI was statistically significant (&lt;i&gt;p&lt;/i&gt; = 0). After chemotherapy, histological examination of surgical specimens identified parametrial involvement in 3 patients. Ultrasonography correctly identified those cases with parametrial infiltration, recording a sensitivity of 100%, specificity of 90.9%, positive predictive value of 50%, and negative predictive value of 100%. The MRI had a sensitivity of 100%, specificity of 45.5%, positive predictive value of 14.3%, and negative predictive value of 100%, respectively. The concordance in the identification of the presence/absence of infiltration between US and MRI with histology was 90% (&lt;i&gt;p&lt;/i&gt; = 0.001) and 61%, respectively, after chemotherapy treatment. Particularly, in defining the degree of infiltration, the agreement between US and MRI with histology was 90 and 58%, respectively. &lt;b&gt;&lt;i&gt;Conclusion:&lt;/i&gt;&lt;/b&gt; In locally advanced cervical cancer patients, 2D/3D TV-US can be considered accurate in the evaluation of parametrial infiltration to assess the response to NACT. It could be included as a diagnostic method in the preoperative work-up of cervical cancer.

Exploring the cost-effectiveness of the OSNA method for patients facing endometrial cancer: Insights from a single-institution experience

The one-step nucleic acid amplification (OSNA) method has emerged as a potential alternative to ultrastaging for diagnosing lymph node metastasis. This study aims to assess the cost-effectiveness of the OSNA technique compared to ultrastaging for detecting SLN metastasis in patients with early-stage endometrial cancer (EC). This retrospective, observational, single-center study included 30 patients with EC who underwent surgical treatment. SLN mapping was performed using an intracervical injection of indocyanine green. SLNs were analyzed and classified as negative, as having isolated tumor cells, micrometastases, or macrometastases. The study evaluated and quantified the costs of the OSNA and ultrastaging procedures in euros. A total of 54 lymph nodes were analyzed using both the OSNA and ultrastaging methods. Concordant negativity was identified in 48 cases (89 %), while micrometastases were detected concordantly in 1 case (1.8 %). The cost for a single ultrastaging lymph node analysis, including immunohistochemistry, is approximately € 250, with a total processing time of 2 days. The cost for a single OSNA analysis is approximately € 236, boasting a significantly shorter processing time of 30-40 min. While materials and staff costs are comparable between both techniques, considering time-related expenses, the OSNA method proves to be more cost-effective than ultrastaging (p < 0.001). The OSNA method demonstrates diagnostic accuracy comparable to histopathological examination in detecting lymph node metastases, reinforcing its reliability for lymph node assessment in patients with EC. Our cost analysis reveals that the OSNA method is more cost-effective than ultrastaging when time-related expenses are considered.

Hormone replacement therapy in gynecological cancer survivors and BRCA mutation carriers: a MITO group survey

Early iatrogenic menopause in gynecological cancer survivors and BRCA mutation (BRCAm) carriers undergoing risk-reducing salpingo-oophorectomy (RRSO) is a major health concern. Hormone replacement therapy (HRT) is the most effective remedy, but remains underused in clinical practice. The Multicenter Italian Trials in Ovarian cancer and gynecologic malignancies (MITO) group promoted a national survey to investigate the knowledge and attitudes of healthcare professionals regarding the prescription of HRT. The survey consisted of a self-administered, multiple-choice 45-item questionnaire, available online to all MITO members for 2 months starting from January 2022. A total of 61 participants completed the questionnaire (47 out of 180 MITO centers; compliance: 26.1%). Most respondents were female (73.8%), younger than 50 years (65.6%), and gynecologic oncologists (55.7%), working in public general hospitals (49.2%). An 84.4% of specialists actively discuss HRT with patients and 51.0% of patients ask the specialist for an opinion on HRT. The rate of specialists globally in favor of prescribing HRT was 22.9% for ovarian cancer, 49.1% for cervical cancer, and 8.2% for endometrial cancer patients. Most respondents (70.5%) believe HRT is safe for BRCA-mutated patients after RRSO. Nearly 70% of physicians prescribe systemic HRT, while 23.8% prefer local HRT. Most specialists recommend HRT for as long as there is a benefit and generally for up to 5 years. Real-world data suggest that many healthcare professionals still do not easily prescribe HRT for gynecological cancer survivors and BRCA mutation carriers after RRSO. Further efforts are required to implement the use of HRT in clinical practice and to support both clinicians in recommending HRT and patients in accepting it.
