Sentinel Lymph Nodes and Precision Surgery in Gynecologic Cancer

Besides histologic features, the presence of nodal metastasis is the most crucial prognostic factor for recurrence and survival for patients with gynecologic cancer. Conventionally, lymphadenectomy has been performed routinely to assess lymphatic metastasis. However, lymphadenectomy may be unnecessary in early-stage gynecologic cancer, because the percentage of patients with lymph node involvement is very low. The recent use of sentinel lymph node mapping has provided high feasibility, safety, and accuracy in the assessment of nodal metastasis. The National Comprehensive Cancer Network Clinical Practice Guidelines have incorporated the sentinel lymph node for nodal evaluation in vulvar, endometrial, and cervical cancers.

Minimally Invasive Robotic Surgery for Gynecologic Cancers: A Review

Minimally invasive robotic surgery has become an effective surgical technique for the treatment of gynecologic malignancies. This article reviews the current utilization of robotic surgery and its role for future treatment in gynecologic oncology.

Preventing Ovarian Cancer in High-risk Women: One Surgery at a Time

Eleven genes have been identified that increase the lifetime risk of developing ovarian cancer. The cumulative cancer risk of ovarian cancer varies with the mutation type and age. Ovarian cancer risk management options include surgical risk reduction with salpingo-oophorectomy and a newer step-wise approach with interval salpingectomy and delayed oophorectomy. Women should be counseled on the pros and cons of hysterectomy in the setting of reducing the risk of other cancers; eliminating the risk of endometrial cancer in Lynch Syndrome, potential risk of serous/serous-like endometrial cancer in BRCA1 carriers, and elimination of progestogen therapy that may increase breast cancer risk.

Integration of Clinical and Molecular Features into Prediction Models for Outcomes in Endometrial Cancer

Endometrial cancer recurrence carries a poor prognosis. The rising incidence of endometrial cancer calls for improvements in treatment of advanced and recurrent diseases. Efforts have been made to molecularly characterize endometrial cancer with the goal of improving therapies. The study presented here describes the utilization of molecular features of endometrial cancer tumors that are likely to recur, along with clinical characteristics utilized together to predict recurrence. This work further studies recurrent endometrial cancers to group them into “clusters” based on the tumor’s molecular makeups with the ultimate aim to focus therapy on the molecular pathways potentially leading to recurrence.

Artificial Intelligence in Gynecologic Imaging

What was done? A review of artificial intelligence (AI) applications for the imaging of uterine fibroids, endometriosis, and adenomyosis. What was found? AI models can assist with the recognition, segmentation, and localization of uterine fibroids, and the differentiation of benign fibroids and sarcomas. Models can aid in the diagnosis of adenomyosis and endometriosis, and the prediction of the impact of endometriosis on fertility. What the findings mean? Deployed thoughtfully, AI tools could reduce variability, shorten read times, and add objective measurements to routine care. Studies evaluating these models are limited by single-institution designs and continued reliance on expert sonologists and radiologists.

Human Papillomavirus Infections and Sequela in Women

Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States, with up to 90% of females infected at some point in their lifetime. While most HPV infections will be cleared by the immune system within 2 years, persistent HPV infection may result in anogenital warts, dysplasia of the cervix, vagina, vulva, and squamous cell carcinoma. This chapter will review the epidemiology, microbiology, progression, and treatment of HPV-related genital disease in women.

Emerging Treatment Options for Cervical Dysplasia and Early Cervical Cancer

Discussion of treatment strategies for cervical cancer precursors, review of medical therapies and emerging therapeutics for treatment of cervical cancers, and updates on new approaches to treating early-stage cervical cancers.

Foreword: Contemporary Recommendations for Cervical Cancer and Anal Cancer Screening and Prevention

Cervical Cancer Screening: Evolution of National Guidelines and Current Recommendations

Cancer of the cervix is preventable through vaccination against human papillomavirus and by screening and treatment of cervical precancers. Cervical cancer screening has evolved since the Pap smear was first discovered in the 1920s. Current guidelines from the US Preventive Services Task Force and the American Cancer Society incorporate the use of cervical cytology and high-risk human papillomavirus tests performed every 3 to 5 years for screening in average-risk asymptomatic patients. Testing should begin at age 21 to 25 years old and stop at 65 years old if sufficient cessation criteria has been met.

Maintenance Therapy in the Primary Treatment of Epithelial Ovarian Cancer

Despite aggressive upfront treatment with a combination of surgery and chemotherapy, most women with advanced epithelial malignancy will experience disease recurrence. The goal of treatment in the recurrent setting shifts away from a curative approach towards palliation of symptoms. In an attempt to delay time to first recurrence, the concept of maintenance chemotherapy emerged. This paper reviews the available literature evaluating the use of maintenance chemotherapy in the primary treatment setting and its effect on progression-free survival and overall survival.

When Should Prophylactic Oophorectomy Be Recommended at the Time of Elective Hysterectomy?

Gynecologists are frequently confronted with the decision of when to recommend oophorectomy at the time of an elective hysterectomy. When deciding if oophorectomy should be recommended, first a careful history and risk assessment must be performed to determine if a patient is a candidate for a risk-reducing oophorectomy. If the patient does not have a hereditary ovarian cancer risk, then it is recommended the surgeon carefully consider the implications of ovarian removal on the health of their patient. This review covers the potential benefits and risks of prophylactic oophorectomy and offers a decision aid for when to recommend this procedure.

Characterization of a TP53 Somatic Variant of Unknown Function From an Ovarian Cancer Patient Using Organoid Culture and Computational Modeling

In our proof-of-concept study of 1 patient with stage IIIC carcinosarcoma of the ovary, we discovered a rare mutation in the tumor suppressor, TP53, that results in the deletion of N131. Immunofluorescence imaging of the organoid culture revealed hyperstaining of p53 protein. Computational modeling suggests this residue is important for maintaining protein conformation. Drug screening identified the combination of a proteasome inhibitor with a histone deacetylase inhibitor as the most effective treatment. These data provide evidence for the successful culture of a patient tumor and analysis of drug response ex vivo.

Maintenance Therapy in the Treatment of Recurrent Epithelial Ovarian Cancer

A diagnosis of recurrent epithelial ovarian cancer carries with it a very poor prognosis despite aggressive chemotherapy with or without secondary surgical cytoreduction. Recently, maintenance treatment after second-line chemotherapy has gained momentum given promising results of antiangiogenics and PARP inhibitors used in this setting. When used appropriately, these agents may provide a meaningful survival benefit with minimal effects on quality of life. This paper reveals the current literature evaluating the use of maintenance therapy in the recurrent setting for the epithelial ovarian, fallopian tube, or primary peritoneal cancers.

Prediction of Epithelial Ovarian Cancer Outcomes With Integration of Genomic Data

Some of the patients with epithelial ovarian cancer will not respond to initial therapy. These patients have a poor prognosis. Our aim was to identify patients with a worse prognosis by integrating clinical, pathologic, and genomic data. Using publicly available genomic data and integrating it with clinical data, we significantly improved the prediction of patients with worse surgical outcomes and those who do not respond to initial chemotherapy. We further improved these models with more precise data collection and better understanding of the genetic background of the studied population. Better prediction will lead to better patient classification and opportunities for individualized treatment.

Enhanced Recovery After Surgery Updates in Gynecologic Oncology Surgery

In this review article, we aim to provide a comprehensive update on enhanced recovery after surgery (ERAS) in gynecologic oncology. Specifically, we focus on topics including pelvic exenterations, hyperthermic intraperitoneal chemotherapy, vulvar surgery, optimal intraoperative fluid management, postoperative pain control, and disparities in ERAS care. In addition, we discuss contemporary practice patterns including prehabilitation in the ERAS pathway and smartphone applications for postoperative care in gynecologic oncology patients.

Advanced Ovarian Cancer: Weighing the Risks and Benefits of Surgery

Treatment for patients with advanced ovarian cancer includes a combination of platinum-based chemotherapy and maximally cytoreductive surgery. The 2 options for initial treatment include upfront surgery followed by adjuvant chemotherapy or neoadjuvant chemotherapy followed by interval surgery. Deciding between which approach is a on the basis of several factors: (1) resectability of disease; (2) patient factors such as age, albumin, and body mass index; (3) patient wishes; and (4) overall functional status. Research is needed to further refine these approaches and create a patient-focused treatment plan which includes novel factors such as molecular subtype of disease and frailty and sarcopenia.

The Current State—or Lack Thereof—of Screening and Prevention for Gynecologic Malignancies for Patients With Lynch Syndrome

Lynch syndrome (LS) is an autosomal dominant genetic disorder that results in an increased risk of ovarian and endometrial cancers. The aim of this paper was to explore the management of this risk through screening and prevention. Published materials and evidence were explored and summarized. This paper demonstrated that while there has been increased awareness and advances in the identification and diagnosis of patients with LS, recommendations for screening and prevention remain less evidence-based. In decisions of management of patients with LS, a shared decision-making model should be used considering individual patient goals.

Genetic Predisposition for Gynecologic Cancers

Hereditary cancer syndromes (HCS) are responsible for up to 10% of all cancers. At present, the majority of cancer susceptibility testing is initiated after a cancer diagnosis. There exists a significant opportunity for primary care providers including general obstetrician-gynecologists to engage in hereditary cancer risk assessment through adequate family history evaluation, initiation of genetic testing, and following the recommendations of national organizations. Identifying hereditary cancer genes may prompt primary prevention efforts such as enhanced screening, prevention, or personalized care strategies. We will review the literature regarding the approach and assessment of the most common gynecologic HCS.

Current Science and Practice of Surgical and Nonsurgical Opportunities for Ovarian Cancer Prevention

Due to improved understanding of ovarian cancer pathogenesis, we have an unprecedented chance to decrease the burden of disease by maximizing opportunities for prevention. Innovations in surgical options for prevention stem from the discovery that many cases directly or indirectly arise from the fallopian tube. Surgical prevention with salpingectomy alone decreases risk by ≥50%. Effective hormonal and nonhormonal chemopreventive agents are also available. Risk stratification is key to ensuring that options for prevention are appropriately matched to individual risk profile. This evidence-based review provides a critical appraisal of the translational health research endeavors supporting ovarian cancer prevention in clinical practice.

Artificial Intelligence for Genetic Cancer Risk Assessment in Gynecologic Oncology

Hereditary cancer syndromes are associated with up to 25% of ovarian and 5% of endometrial cancers, yet rates of genetic testing and counseling remain low. Artificial intelligence (AI) offers new opportunities to streamline risk assessment, enhance gene variant interpretation, and expand access to genetic counseling. This narrative review synthesizes current evidence on AI applications in gynecologic cancer genetic risk assessment, including chatbot-based risk assessment, natural language processing of electronic records, and machine-learning approaches to variant classification. We highlight key challenges, including data bias, privacy, and implementation barriers, and outline future directions for AI technologies in gynecologic cancer genetic risk assessment.

Uptake of Cascade Genetic Testing for Hereditary Breast and Ovarian Cancer: A Systematic Review and Meta-Analysis

This is a systematic review and meta-analysis evaluating the uptake of cascade genetic testing for hereditary breast and ovarian cancer syndrome. Among 30 studies included for meta-analysis, the uptake of cascade genetic testing was 33% (95% CI 25%-42%), with higher uptake rates among females compared with male relatives, and among first-degree compared with second-degree relatives. These findings indicate suboptimal uptake of cascade genetic testing among people at risk for hereditary breast and ovarian cancer syndrome, representing a missed opportunity for cancer prevention and early detection. There is a need for interventions to improve uptake rates.

Genetic Implications for Cancer Management: The Changing Landscape of Poly (ADP-ribose) Polymerase Inhibitor Indications in the Treatment of Ovarian Cancer

Between December 2014 and May 2020, the United States Food and Drug Administration approved 9 indications for poly (ADP-ribose) polymerase (PARP) inhibitor use in ovarian cancer. Between June 2022 and September 2022, all 3 indications for PARP inhibitor treatment of recurrent ovarian cancer were withdrawn. Between November 2022 and September 2023, all 3 indications for PARP inhibitor maintenance therapy in recurrent ovarian cancer were restricted. The 3 indications for PARP inhibitor maintenance therapy in newly diagnosed advanced ovarian cancer are unchanged. This article reviews the timelines and data leading to regulatory changes for PARP inhibitor use in ovarian cancer in the United States.

Management of Abnormal Cervical Cancer Screening Test: A Risk-based Approach

Cervical cancer screening plays a major role in preventing cervical cancer. The field is based on understanding the natural history of human papillomavirus and its role in cervical cancer. Screening has evolved to assessing the risk for cervical intraepithelial neoplasia grade 3, a true cancer precursor, and performing diagnostic tests based on those risks. This article summarizes the present state of management of abnormal cervical cancer screening tests in the United States, based on the most recent 2019 American Society of Colposcopy and Cervical Pathology guidelines.

HPV Testing and its Role in Cervical Cancer Screening

The recognition that persistent infection with carcinogenic human papillomavirus (HPV) is a necessary cause of cervical precancer and cancer has led to the introduction of HPV testing into cervical cancer screening, either as a primary screening test or in conjunction with cervical cytology (i.e., co-testing). HPV testing has much higher sensitivity for detection of cervical precancer and provides greater long-term reassurance if negative compared to cytology. However, most HPV infections are transient, and do not progress to invasive cancer, thus triage tests are required to identify individuals who should be referred to colposcopy for diagnostic evaluation. This chapter begins with a description of the biology, natural history, and epidemiology of HPV as a foundation for understanding the role of HPV in cervical carcinogenesis. This section is followed by a detailed discussion regarding the introduction of HPV-based testing and triage into cervical cancer screening and management. Summarized triage tests include cervical cytology, HPV genotyping, p16/Ki-67 dual stain, and HPV and cellular methylation markers. The final section of this chapter includes an important discussion on cervical cancer disparities, particularly within the United States, followed by concluding remarks.

Cervical Cancer Prevention in Low- and Middle-Income Countries

Cervical cancer is one of the commonest cancers afflicting women in low and middle income countries, however, both primary prevention with human papillomavirus vaccination, and secondary prevention with screening programs and treatment of preinvasive disease are possible. A coordinated approach to eliminating cervical cancer, as has been called for by the World Health Organization, requires a complex series of steps at all levels of a health system. This article outlines the current state of cervical cancer prevention in low and middle income countries, the innovations being employed to improve outcomes, and consideration of the next steps needed as we move towards global elimination.

Transforming Gynecologic Cancer Care Through Artificial Intelligence

Artificial intelligence (AI) is rapidly reshaping gynecologic oncology across the continuum of care. This clinician-focused review synthesizes current evidence for AI-enabled prevention and screening (HPV-informed risk models, AI-assisted colposcopy), early detection and diagnosis (radiomics, liquid biopsy, and digital pathology), prognosis and risk prediction (multimodal models integrating clinical, imaging, histology, and genomics), and treatment guidance (surgical planning and response-predictive therapeutics). Across domains, deep learning and emerging multimodal models consistently match or surpass conventional approaches, offering gains in accuracy, speed, and reproducibility while enabling biologically informed decision support. We outline practical pathways for clinical integration, human-in-the-loop workflows, explainable outputs, and ethical and regulatory guardrails. Priority future directions include rigorous prospective trials, real-world performance tracking, and equity-centered deployment to ensure benefits generalize across diverse populations. Taken together, AI has the potential to enhance precision, consistency, and access in gynecologic cancer care, not by replacing clinicians, but by augmenting expertise at scale.

Female Sexual Health and Cancer

As the majority of female cancer survivors can now expect to live long lives beyond cancer diagnosis and treatment, there is a growing need to address the significant late effects of treatment. Unfortunately, sexual health remains a primary concern that often goes unaddressed among female cancer survivors. Sexual dysfunction is one of the most common and distressing effects of treatment. Management of issues related to sexual health and sexual function depends upon the type of malignancy, stage and other tumor characteristics, treatment, and the history, concerns, and goals of the individual patient.

Updates in Cervical Cancer Treatment

Although rates of cervical cancer in the United States have been declining due to vaccination and screening efforts, it remains the fourth most common cancer in women worldwide and is still far from being eradicated, even in developed nations. This review discusses recent developments in cervical cancer treatment and reviews the literature supporting recent practice changes encompassing staging, surgical management, radiation, chemotherapy, targeted agents including immunotherapy, and imaging.

Differential Receipt of Genetic Services Among Patients With Gynecologic Cancer and Their Relatives: A Review of Challenges to Health Equity

Up to 14% of endometrial cancers and 23% of epithelial ovarian cancers are associated with genetic predispositions. Referral for genetic testing and counseling can significantly impact a patient’s oncologic outcomes. However, significant disparities in genetic referral and testing exist within medically underserved and minority populations in the United States. These disparities in care and access to care are multifactorial, often involving patient-level, health care-level, and system-level factors. In this review, we focus on disparities in genetic testing among patients with ovarian and uterine cancer, and the missed opportunities for primary cancer prevention among their relatives.

What About the Others? Clinical Management of Gynecologic Cancer Risk in Patients With Moderate-Risk Hereditary Cancer Genes (ATM, BRIP1, RAD51C, RAD51D, and PALB2)

Hereditary cancer syndromes associated with gynecologic malignancies account for up to 18% of all cases of ovarian, uterine, and cervical cancers, and identification of these syndromes has implications for cancer screening and risk reduction techniques in affected patients. The associated cancer risks with moderate-penetrance genes are rapidly evolving and present variable risks for the provider counseling the patient. In this review, we detail the cancer risk and management of patients with germline PV in the moderate-risk hereditary cancer genes ATM, BRIP1, RAD51C, RAD51D, and PALB2.
