Real-life clinical benefit of oral metronomic cyclophosphamide administration in elderly and heavily pretreated epithelial ovarian cancer patients.

PURPOSE: Oral metronomic cyclophosphamide (OMC) implicates the daily administration of low doses of chemotherapy. Its antitumor activity combined with an oral administration route and a good toxicity profile makes OMC an attractive option for heavily pretreated patients. We retrospectively evaluated OMC's clinical benefit and objective response in recurrent ovarian cancer patients. METHODS: This is a retrospective observational study involving patients treated with OMC (50 mg daily) from 2017 to 2022 at the Academic Division Gynaecology, Mauriziano Hospital, Torino, Italy. Clinical benefit assessment included CA125 response, radiological response, and reported symptomatic improvement. Toxicities were reported using Common Terminology Criteria for Adverse Events version 5.0. RESULTS: Thirty-eight patients (average age 72, range 49-88) were included. 90% had FIGO stage III/IV at diagnosis and 64% underwent ≥ 3 previous lines of chemotherapy. Before OMC, 79% had ECOG 1 or 2. 8.6% of patients had a partial response (PR), and 40% a stable disease (SD). Median duration of response was 7.4 months. After 3 months on OMC, 51% experienced symptom improvement, and 53.3% experienced Ca125 reduction or stabilization. 66.7% of patients older than 75 responded to treatment; in 40% of cases, responses lasted ≥ 6 months (p = 0.08). No G3-4 hematological toxicities occurred. Nausea and fatigue G1-G2 were reported in 5 (13%) and 13 (34%) cases, respectively. CONCLUSION: OMC is a feasible therapeutic option for recurrent ovarian cancer, providing satisfying clinical responses with a good toxicity profile, even in elderly and heavily pretreated patients with a suboptimal performance status.

New Frontiers in Locally Advanced Cervical Cancer Treatment.

Despite the introduction of targeted vaccines and screening protocols, locally advanced cervical cancer represents a median proportion of 37% among all cervical carcinomas. Compared to early stages, it presents significantly lower cure rates, with a 5-year disease-free survival rate of 68% and a 5-year overall survival rate of 74%. According to current guidelines, definitive radiotherapy with concomitant chemotherapy represents the gold standard for locally advanced cervical cancer treatment. However, a significant number of patients relapse and die from metastatic disease. The aim of this narrative review is to examine the recent advancements in treating locally advanced cervical cancer, exploring new frontiers in therapeutic approaches. The PubMed database and clinical trial registries were searched to identify relevant articles published on locally advanced cervical cancer treatment up to March 2024, mainly focusing on papers published in the last decade. Abstracts presented at major international congresses that bring relevant evidence were included. Progress achieved in refining radiotherapy techniques, recent evidence regarding neoadjuvant treatment preceding surgery or concurrent chemoradiotherapy, and key findings concerning adjuvant treatment are thoroughly explored. Furthermore, a comprehensive review of prominent phase II and phase III trials examining the integration of immune checkpoint inhibitors is conducted, analyzing the various contexts in which they are applied. In light of the new evidence that has emerged in recent years and is discussed in this article, the appropriate selection of the most suitable therapeutic approach for each patient remains a complex but crucial issue.

Nodal staging in high and high-intermediate risk endometrial cancer surgery: Which role in the molecular classification era?

OBJECTIVES: Nodal staging contributes to risk group definition and the indication to adjuvant treatment in endometrial cancer (EC) patients. However, the role of nodal assessment evolved and requires redefinition. Primary outcome of the study was to assess the impact of surgical nodal staging in defining high-risk (HR) EC. Secondary outcome was to evaluate the contribution of nodal assessment to the decision for adjuvant treatment in both high-risk and high-intermediate risk (HIR) patients submitted to surgery. METHODS: Clinical stage I-II EC patients with postoperative diagnosis of HR and HIR disease were included. The contribution of nodal staging in prognostic groups allocation was assessed by reviewing HR patients to identify those without any other feature of such class (non-endometrioid histology, p53abn immunohistochemistry, post-operative T3-T4 disease) and HIR cases to assess how nodal staging affected adjuvant treatment indication. Descriptive statistics were conducted to describe the two populations. RESULTS: Fifty-seven patients were included, 46 with HR and 11 with HIR disease. Chemotherapy and external-beam radiotherapy (EBRT) were proposed in 40 HR patients. Considering histology, immunohistochemical profile and FIGO stage, high risk classification was exclusively relied on nodal involvement in 2/46 cases (4.3 %). Omitting retroperitoneal staging, one of them would have been classified in the intermediate risk group and the other as HIR: without nodal staging, chemotherapy and EBRT would have been omitted in 1/40 (2.5 %) case. Among HIR patients, chemotherapy was proposed in 7/11 cases and EBRT in all cases. Adjuvant chemotherapy was indicated in 5/6 (83.3 %) and omitted in 1/6 (16.7 %) pN0 patient (stage Ib G2, substantial LVSI). In HIRpN0 patients, omitting nodal staging could have changed adjuvant treatment indication in 1/6 (16.7 %) case. In HIRpNx patients, adjuvant chemotherapy was omitted in one patient (stage II, grade 2 and LVSI negative): nodal staging unavailability might have changed indication to chemotherapy in 1/5 (20 %) case, without changing indication to EBRT. Unavailable nodal staging could globally be related to omission of chemotherapy in 2/57 (3.5 %) patients and of EBRT in 1/57 (1.8 %) patient. CONCLUSIONS: In this series, nodal staging had limited impact on definition of HR class and on the choice of adjuvant treatment in HR and HIR EC patients.

Ultrasonographic diagnosis of adnexal masses: interobserver agreement in the interpretation of videos, using IOTA terminology.

OBJECTIVES: Aim of this study is to estimate interobserver agreement in classifying adnexal tumors using IOTA terms, simple rules and subjective assessment. In addition, we related observers' accuracy with their experience in gynecological ultrasonography and the year of IOTA certification. METHODS: Eleven observers with three different levels of experience evaluated videoclips of 70 adnexal masses, defining tumor type according to IOTA terms and definitions, classifying the mass using IOTA Simple rules and Subjective assessment as well as providing Color Score evaluation. Sensitivity, specificity and area under the ROC curve were calculated and the year of IOTA certification was related with operators' accuracy through Pearson correlation coefficient. Interobserver agreement was estimated calculating percentage of agreement, Fleiss kappa and Cohen's kappa. RESULTS: We found a positive correlation between the year of IOTA certification and operators' accuracy (Pearson coefficient 0.694), especially among the observers with the least experience, the residents (p = 0.003). For tumor type classification, identification of papillary projections and classification of tumors using subjective assessment, agreement among all observers was moderate (Fleiss kappa 0.455, 0.552, and 0.476, respectively) and increased with the years of experience. Agreement in the application of Simple Rules was moderate in all examiners with IOTA certification, with Fleiss kappa in the range of (0.403, 0.498). For Color Score assignment interobserver agreement among all observers was fair (Cohen's kappa 0.380). CONCLUSIONS: Even among expert examiners, the results of adnexal lesion assessment can be inconsistent. Experience impacts on accuracy and agreement in subjective assessment, while the application of Simple Rules can mitigate the role of experience in interobserver agreement. The knowledge of IOTA models among residents seams to improve their diagnostic accuracy, showing the benefits of IOTA terminology for in training sonographers.

Development and clinical application of a tool to identify frailty in elderly patients with gynecological cancers.

OBJECTIVE: Frailty is more reliable than chronological age in predicting the effectiveness and tolerability of treatments in cancer patients. An increasing number of screening tools have been proposed, however none have received unanimous consent or been specifically designed for women with gynecological malignancies.This study's aim was to develop a clinical application of a screening tool to identify frail patients >70 years old diagnosed with either ovarian or endometrial cancers. METHODS: A 20 item questionnaire was developed and administered to the cohort before surgery or neoadjuvant chemotherapy. A cut-off for frailty definition was determined by analyzing the correlation of questionnaire scores with the completion of treatments. The association between frailty and treatment related complications was assessed using a Chi-squared test for categorical variables and a t-test for continuous variables. RESULTS: Our study included 100 patients, 50% diagnosed with endometrial cancer and 50% with ovarian cancer. A questionnaire score of 4 was the best cut-off for frailty definition (sensitivity 77%, specificity 100%). Surgical grade III and grade IV complications were observed only in frail patients (p=0.01) and hospitalization was significantly longer in frail women affected by ovarian cancer (p=0.01). Frail patients were more exposed to chemotherapy administration delay (p=0.0005), treatment discontinuation (p=0.001) and hematological toxicities, especially anemia ≥grade 2 (p=0.009) and thrombocytopenia any grade (p=0.0001). CONCLUSION: With a cut-off score of 4, our tool can identify frail patients with significantly higher incidence of grade III-IV postoperative complications, length of stay, medical treatment discontinuation rates and hematological toxicities.
