Minimally Invasive Surgery in the Management of Advanced Epithelial Ovarian Cancer: A Comprehensive Analysis of Current Evidence and Clinical Applications

Background and Objectives: Advanced epithelial ovarian cancer (AEOC) often requires extensive cytoreductive surgery. Minimally invasive surgery (MIS), especially diagnostic laparoscopy, is increasingly used to assess resectability and guide treatment. This review aimed to evaluate the evidence on MIS in AEOC, focusing on its diagnostic and therapeutic roles in primary and interval debulking surgery (PDS and IDS), and its impact on perioperative and oncologic outcomes. Materials and Methods: A structured literature review was performed using PubMed, MEDLINE, Embase, Scopus, and the Cochrane Library, including studies published between January 2000 and June 2025. Eligible studies involved laparoscopic or minimally invasive cytoreduction in PDS or IDS, reporting surgical feasibility, perioperative results, and oncologic outcomes. Data were synthesized qualitatively due to heterogeneity across studies. Results: Observational studies indicate that diagnostic laparoscopy predicts resectability, reduces futile laparotomies, and improves patient selection for primary surgery. In selected patients, non-randomized cohorts of laparoscopic PDS report R0 resection rates up to 95%, with low morbidity and short hospital stays. In IDS after neoadjuvant chemotherapy, MIS has been associated with reduced blood loss, fewer complications, and faster postoperative recovery, while showing progression-free and overall survival comparable to laparotomy in retrospective series. Conversion to open surgery was generally reported in fewer than 10% of cases when stringent selection criteria were applied. Conclusions: Diagnostic laparoscopy is a valuable tool for accurate preoperative evaluation and surgical planning in EOC. MIS, particularly for IDS, appears to offer reduced morbidity and equivalent survival outcomes when performed in experienced centers, whereas its application in PDS remains investigational and should be reserved for highly selected cases. These conclusions are limited by the predominance of retrospective evidence and the heterogeneity in patient selection and surgical expertise.

Is less already enough? Minimally invasive interval debulking surgery for advanced ovarian cancer

Minimally invasive surgery (MIS), including laparoscopy and robotic-assisted techniques, has increasingly been explored as an alternative to laparotomy for interval debulking surgery (IDS) following neoadjuvant chemotherapy (NACT) in advanced epithelial ovarian cancer (EOC). This systematic review evaluates the current evidence on the surgical feasibility, patient selection, perioperative outcomes, and oncological safety of MIS in this setting. Following PRISMA guidelines, a systematic search of PubMed, Embase, Scopus, Cochrane Library, and ClinicalTrials.gov was conducted for studies published between January 2015 and June 2025. Eligible studies included prospective and retrospective cohorts, randomized trials, and meta-analyses reporting outcomes of MIS for IDS in FIGO stage III-IV EOC patients after NACT. Data extraction and risk of bias assessment were independently performed by two reviewers. Sixteen studies involving 9299 patients were included. MIS demonstrated high rates of complete cytoreduction (R0: 85-100 %) in selected patients, with significantly lower estimated blood loss, shorter hospital stays, fewer major complications, and earlier resumption of chemotherapy compared to open surgery. Operative times were generally longer, and conversion rates varied by tumor burden and selection criteria. Oncologic outcomes, including progression-free and overall survival, were comparable between MIS and laparotomy across multiple studies. Robotic-assisted IDS showed similar feasibility and outcomes, but evidence for this approach was mainly derived from small, retrospective cohorts. In appropriately selected patients and experienced centers, MIS for IDS appears to be a feasible and oncologically safe alternative to open surgery, offering meaningful perioperative benefits. Further randomized studies are needed to confirm long-term oncological equivalence.

Enhancing surgical precision in ovarian cancer with FRα-fluorescence-guided surgery

Complete cytoreduction is a key prognostic factor in advanced ovarian cancer. Folate receptor alpha (FRα)-targeted intraoperative fluorescence imaging has emerged as a promising tool to enhance identification of tumor localization. Agents like pafolacianine (OTL38) and EC17 improve real-time visualization of malignant lesions, overcoming limitations of conventional methods relying on visual inspection and palpation. we conducted a systematic review to evaluate the safety, efficacy, and feasibility of FRα-targeted fluorescence imaging in ovarian cancer surgery. Studies were identified through comprehensive searches in PubMed, Scopus, and Web of Science. Clinical and preclinical studies assessing FRα-targeted agents with near-infrared or other fluorescence modalities were included. Bias risk was assessed using the Cochrane Risk of Bias Tool for randomized trials and the Newcastle-Ottawa Scale for non-randomized studies. Eleven studies, including clinical and preclinical trials, were analyzed. OTL38 significantly improved lesion detection, identifying additional malignant lesions in 33 % of patients undergoing debulking surgery and enhancing detection by 29 % over standard methods, with sensitivity exceeding 85 %. EC17, assessed in smaller studies, identified 16 % more malignant lesions undetected by conventional methods, though autofluorescence was a challenge. Adverse events, predominantly mild, included nausea, vomiting, and transient skin flushing. FRα-targeted imaging may enhance lesion detection during cytoreductive surgery, increasing resection completeness. While EC17 shows feasibility, larger trials support the potential of OTL38. Future research should optimize imaging agents to reduce autofluorescence and assess their impact on survival outcomes.

Laparoscopic management of symptomatic uterine myoma in pregnancy: A case report and critical analysis of literature

Abstract Abdominal pain during pregnancy poses diagnostic and management challenges. Uterine leiomyomas complicate 2 to 10% of pregnancies, with severe pain in some cases necessitating surgical intervention. While myomectomy during pregnancy is generally avoided due to increased vascularity and risk of hemorrhagic complications, specific indications warrant consideration, such as severe pain from torsion, hemoperitoneum, or red degeneration. We describe a case of acute abdominal pain at 19 weeks of pregnancy caused by acute uterine myoma degeneration, detailing the diagnostic process, differential diagnosis, and treatment. Our case, along with a discussion of the scarce available literature, highlights that laparoscopic myomectomy during pregnancy is a feasible option for managing symptomatic fibroids. Timely diagnosis, centralized care, and tailored surgical planning are critical to optimizing maternal and fetal outcomes.

Cold Knife Versus Carbon Dioxide for the Treatment of Preinvasive Cervical Lesion

Background and Objectives: Cervical cancer (CC) represents a significant health concern worldwide, particularly for younger women. Cold knife (CK) conization and carbon dioxide (CO2) laser conization are two techniques commonly used to remove pre-invasive lesions, offering a potential curative intent in cases of incidental diagnosis of CC. This study aimed to assess the clinical implications and pathological outcomes of CK vs. CO2 laser conization for pre-invasive lesions. Materials and Methods: We retrospectively analyzed women who underwent CO2 or CK conization for high-grade preinvasive lesions (CIN2/3, CIS and AIS) between 2010 and 2022. Patient demographics, surgical details and pathological outcomes were collected. Pregnancy outcomes, including composite adverse obstetric rates, and oncological follow-up data, were also obtained. Results: In all, 1270 women were included; of them, 1225 (96.5%) underwent CO2, and 45 (3.5%) underwent CK conization. Overall, the rate of positive endocervical or deep margins was lower with CO2 laser compared to CK (4.3% vs. 13.3%, p = 0.015). Incidental CC was diagnosed in 56 (4.4%) patients, with 35 (62.5%) squamous and 21 (46.6%) adenocarcinomas. In a multivariate regression model, the relative risk for positive endocervical or deep margins is significantly greater in cases of incidental diagnosis of CC (p < 0.01). In cases of incidental diagnosis of CC, we found that the probabilities of having either positive endocervical or deep margins after CO2 laser or CK conization are similar, with a higher risk in case of adenocarcinoma lesion. Among women with CC, 42 (75%) opted for radical treatment, while 14 (25%) underwent a follow-up. Only one woman (7.1%) in the follow-up group, who had undergone CK conization, experienced a composite adverse obstetric outcome. No recurrences were observed after a median follow-up of 53 months. Conclusions: CO2 laser conization achieved a lower positive margin rate overall. CK and CO2 conization appear to be equivalent oncological options for incidental CC.

Electronic nose-based volatile organic compound profiling in gynecologic oncology: current evidence and diagnostic accuracy

Volatile organic compounds profiling has emerged as a promising approach for cancer detection. Electronic noses are portable sensor-based devices capable of recognizing volatile organic compound patterns in various biological matrices, offering a rapid, non-invasive, and cost-effective diagnostic alternative. The aim of this systematic review was to evaluate the diagnostic performance of electronic noses in gynecologic oncology and to delineate their technical characteristics. This review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and was registered in International Prospective Register of Systematic Reviews (CRD420251122293). PubMed, Scopus, and Google Scholar were searched up to August 2025. Eligible studies included prospective investigations evaluating volatile organic compound analysis through electronic noses in ovarian, cervical, endometrial, and vulvar cancers, as well as high-grade squamous intraepithelial lesions, using histopathology as the reference standard. Diagnostic performance parameters were extracted, and the risk of bias was assessed with Quality Assessment of Diagnostic Accuracy Studies 2. No meta-analysis was performed due to study heterogeneity. Fifteen studies with a total of 1224 patients were included. Among them, 562 (45.9%) had gynecologic malignancies, and 662 (54.1%) served as controls. Ten studies (66.7%) investigated ovarian cancer, 4 (26.7%) cervical cancer, and 1 (6.7%) high-grade squamous intraepithelial lesions of the cervix; no studies evaluated endometrial or vulvar cancers. Biological matrices analyzed included breath (33.3%), urine (20%), tissue (20%), plasma (6.7%), genitourinary secretions (6.7%), or combined samples (6.7%). Reported diagnostic performance ranged from 71% to 97.7% for sensitivity, from 63% to 100% for specificity, and from 71% to 95% for accuracy across all cancer types. In ovarian cancer studies, sensitivity ranged from 71% to 97.7%, specificity from 63% to 91.4%, and accuracy from 71% to 87%. In cervical cancer studies, sensitivity ranged from 88% to 93%, and specificity from 85% to 100%. Electronic nose technologies show encouraging diagnostic accuracy in gynecologic oncology, particularly for cervical cancer, whereas performance in ovarian cancer remains more variable depending on the biological matrix and comparator group. Despite promising results, the lack of standardized protocols and the heterogeneity of current evidence limit immediate clinical translation. Larger, multicenter, and standardized studies are needed to validate their integration into diagnostic workflows.
