Uterus didelphys and cervical cancer: A case report.

Background: Deficiencies in the merging process of the paramesonephric ducts as part of the embryonal development lead to anomalies of the uterus, cervix, fallopian tubes and proximal vagina (Müllerian malformations). The co-occurrence with cervical cancer is rare and there are no standardized protocols for managing urogenital anomalies in the realm of oncologic treatment for gynecological carcinomas. Case report: A symptom-free 41-year-old woman (gravida 0) presented at our clinic with an externally obtained AGC-FN (atypical glandular cells - favor neoplastic) finding in the Papanicolaou (Pap) smear test and persistent positivity for human papillomavirus (HPV) type 16. Sample biopsies from the portio vaginalis uteri confirmed a cervical intraepithelial neoplasia (CIN) III/ high grade squamous intraepithelial lesion (HSIL), invasive carcinoma could not be ruled out. The examinations revealed the incidental finding of a uterus didelphys and renal agenesis on the left side. After cervical conization, the patient was diagnosed with squamous cell carcinoma of the cervix. Guideline-compliant treatment with laparotomic hysterectomy according to Piver type II following a staging laparoscopy with sentinel lymphadenectomy was performed. A customized protocol was used for the indocyanine green (ICG) injection as part of the sentinel lymph node examination, tailored to the patient's anatomical characteristics. Discussion: Müllerian malformations may impede detection and treatment of gynecological carcinomas. Individualized therapy planning is necessary to meet the anatomical peculiarities of the genital anomaly. In instances of concomitant urinary tract anomalies, protective measures are imperative to safeguard normal kidney function. Conclusion: The current case demonstrates the successful implementation of guideline-compliant therapy for early-stage cervical cancer in an individual with Müllerian malformation.

Evaluation of ChatGPT's Potential in Tailoring Gynecological Cancer Therapies.

BACKGROUND/AIM: Demographic change and increasing complexity of therapy decisions lead to a growing burden on the healthcare system, necessitating efforts to simplify and enhance the efficiency of patient care. The present study evaluates ChatGPT's ability to provide therapy recommendations for gynecological malignancies that are both in line with the local guidelines and individually tailored to the patient. PATIENTS AND METHODS: Sixteen patients with endometrial, cervical, and ovarian cancer who were treated in the gynecological clinic of the University Hospital Erlangen from January 2022 to August 2023 were included in the analysis. Data collected within clinical routine care were communicated to the chat-based AI model ChatGPT (version 3.5). ChatGPT's performance generating treatment plans were evaluated using an answer scoring system and descriptive analysis. RESULTS: According to the answer scoring system [range: -1 point (minimum) to 2 points (maximum)], ChatGPT demonstrated a good potential in generating therapy recommendations with an average score of 0.75 points for patients with ovarian cancer, 0.7 points for cervical and 1.5 points for endometrial cancer patients. The most common deductions in points were about incomplete therapy recommendations, whereas contraindicated treatment modalities were rarely suggested. Individual patient characteristics were regularly considered by ChatGPT. ChatGPT reliably indicated aftercare and provided detailed information on preventive measures as well as supportive treatment. CONCLUSION: ChatGPT is a promising tool for the generation of therapy suggestions for gynecological carcinomas with high flexibility in response to individual patient differences. At the current state, however, ChatGPT is not suitable for replacing expert panels.

Update Breast Cancer 2024 Part 1 - Expert Opinion on Advanced Breast Cancer.

Clinical evidence is interpreted based on clinical studies and personal experience which can lead to different interpretations of data. This makes the opinions issued by panels of experts such as the Advanced Breast Cancer Panel which convened in November 2023 for the seventh time (ABC7) particularly important. At the conference, current issues around advanced breast cancer were evaluated by an international team of experts. In 2023 the data on CDK4/6 inhibitors was so extensive that the answers to questions about the sequencing of therapy and the potential use of chemotherapy as an alternative therapy were relatively clear. Moreover, data on antibody drug conjugates which provides a good overview of their uses is available for all molecular subtypes. Some therapeutic settings, including patients with brain metastases or leptomeningeal disease, older patients, locally advanced breast cancer and visceral crises, continue to be particularly important and were discussed in structured sessions. The scientific context of some of the topics discussed at ABC7 is presented and assessed here.

Clinical and Surgical Evaluation of Sentinel Node Biopsy in Patients with Early-Stage Endometrial Cancer and Atypical Hyperplasia.

Introduction: The medical and surgical treatment of endometrial cancer (EC) is evolving toward a more patient-centered and personalized approach. The role of laparoscopic sentinel node biopsy (SNB) for early-stage EC is unclear, and very few data are available for atypical endometrial hyperplasia (AEH). The present study investigated the effectiveness of SNB combined with laparoscopic hysterectomy in patients with early-stage EC and AEH. Patients and Methods: This was a retrospective, single-center cohort study for the period from January 2018 to December 2023. A total of 102 patients with atypical hyperplasia (n = 20) and early-stage EC (n = 82) findings on diagnostic curettage underwent pelvic sentinel node biopsy during the final operation. Results: Eleven patients (55%) who had initially been diagnosed with AEH were found to have EC in the final pathology report. No lymph node metastases were detected in patients who had initially been diagnosed with AEH; a 3.6% rate of positive SNBs was found in patients with EC. Changes in tumor grade occurred in 31.3% of the patients and changes in FIGO stage in 33%. Bilateral sentinel node (SN) mapping was successful in 94.1% of the patients. The postoperative outcomes were comparable to those of routine clinical practice without SNB. Conclusions: SNB can be safely offered to patients who have precursor lesions and early-stage EC without notably extending surgical times or increasing postoperative morbidity. This approach can be considered and is safe for patients diagnosed with AEH, but it appears to have a rather small impact on these patients.

Eosinophil-cationic protein - a novel liquid prognostic biomarker in melanoma.

BACKGROUND: The role of eosinophils in cancer is not yet completely understood, but patients with eosinophilia show a trend towards longer survival in several types of cancer, including melanoma. However, eosinophil count at initial diagnosis of metastatic melanoma does not predict survival. Since eosinophil cationic protein (ECP) mediates anticancer effects, such as tissue remodelling and cytotoxic activity, we investigated this marker as an early prognostic marker in metastatic melanoma. METHODS: Serum of 56 melanoma patients was collected at the time of diagnosis of metastatic disease. ECP levels as measured by ELISA were correlated with overall survival (OS) in patients before systemic therapy with immunotherapy or chemotherapy. Statistical analyses were performed using the Log-Rank (Mantel-Cox) test. RESULTS: The median OS for patients with high serum ECP above 12.2 ng/ml was 12 months (n = 39), compared to 28 months for patients with ECP below this threshold (n = 17; p = 0.0642). In patients with cutaneous melanoma, excluding patients with uveal and mucosal melanoma, the survival difference was even more striking (p = 0.0393). ECP's effect size on OS was observed independently of the consecutive therapy. ECP levels were not correlated with LDH levels. CONCLUSION: ECP seems to be a novel prognostic serum marker for the outcome of melanoma patients, which is independent of LDH and easy to perform in clinical practice. The striking negative prognostic value of high ECP level is unanticipated and can guide patient management.
