The relationship between lymph node metastasis and immunohistochemical molecular subtypes in endometrial cancer: A cohort study of 339 patients

Abstract Aim This study evaluated the association between immunohistochemically (IHC) molecular subtypes and lymph node metastasis (LNM) in endometrial cancer. Methods The study included 339 patients diagnosed with endometrial cancer (EC) confined to the uterus and treated with pelvic ± para‐aortic lymph node dissection (LND), who were included in the study. Patients were divided into two groups: LNM‐negative (Group 1, n  = 289) and LNM‐positive (Group 2, n  = 50). All patients underwent IHC‐based molecular subtype analysis. Demographic, clinical, and histopathological characteristics were evaluated. Results The median age was 62 years (34–79) in Group 1 and 64 years (48–79) in Group 2 ( p  = 0.022). Body mass index (BMI) and parity were similar between the groups ( p  > 0.05). LNM was detected in 14.7% of patients (50/339). Among Group 1, 64.4% (186/289) had a non‐specific molecular profile (NSMP), 20.1% (58/289) had mismatch repair deficiency (MMRd), and 15.5% (45/289) had the p53 abnormal (p53abn) subtype. In contrast, in Group 2, 44% (22/50) were NSMP, 24% (12/50) were MMRd, and 32% (16/50) were p53abn ( p  = 0.008). A statistically significant association was observed between LNM and the p53abn subtype. LNM was present in 26% (16/61) of patients with the p53abn subtype, compared to 17% (12/70) in the MMRd group and 11% (22/208) in the NSMP group. Conclusion While our study identified an association between the p53abn subtype and lymph node metastasis, this finding alone does not support using p53 status in isolation to determine lymphatic staging; instead, it should be considered a complementary marker alongside established clinicopathologic factors.

Impact of molecular and histopathological findings on FIGO 2009 stage I endometrial cancer: Transition to FIGO 2023 staging system

Abstract Aim This study aims to investigate the impact of integrating molecular and histopathological findings into the revised International Federation of Gynecology and Obstetrics (FIGO) 2023 staging system on patients initially diagnosed with stage I endometrial cancer (EC) according to the FIGO 2009 criteria. Methods A cohort of 197 EC patients, initially classified as stage I under FIGO 2009, underwent restaging based on the updated FIGO 2023 criteria. The patients' molecular and histopathological characteristics were documented, and their impact on upstaging was analyzed. Results Molecular profiling was conducted for 81.2% (160/197) of the patients, revealing that 55.3% (109/197) were classified as non‐specific molecular profile, 14.7% (29/197) as mismatch repair deficiency, 11.2% (22/197) as p53 abnormality (p53abn), and 18.8% (37/197) as unknown. Upstaging was identified in 26.9% (43/160) of the 160 patients with known molecular profiles. Among the upstaged patients, 51.2% experienced upstaging due to p53 abnormality, 20.9% due to substantial lymphovascular space invasion (LVSI), 20.9% due to aggressive histological types, and 6.9% due to high grade. Conclusions The introduction of the molecular profile into the revised FIGO 2023 staging system for stage I EC has led to notable changes in the staging of approximately one‐fifth of patients. While p53 abnormalities have emerged as the most influential factor contributing to the upstaging, LVSI and aggressive histological types also represent significant contributing factors.

The impact of human papillomavirus 16/18 positivity on cyberchondria levels in women undergoing colposcopy

SUMMARY OBJECTIVE: The negative consequences of the widespread use of the Internet for health-related information have recently become a topic of research. Recently, the impact of internet information-seeking on anxiety has been defined as cyberchondria, and a standardized scoring system has been developed to document it. However, the significance of this scoring system in gynecologic oncology has not yet been established. Therefore, the aim of this study was to evaluate the impact of human papillomavirus 16/18 positivity on the level of cyberchondria in women with human papillomavirus positivity undergoing colposcopy. METHODS: The study included 333 women with human papillomavirus 16/18 and other high-risk human papillomavirus positivity who underwent colposcopy in the gynecologic oncology clinic. Participants were divided into two groups: human papillomavirus 16/18 positive (Group 1, n=201) and other high-risk human papillomavirus positive (Group 2, n=132). Both groups were administered the short form of the Cyberchondria Severity Scale (CSS-12). Demographic and clinical findings and cyberchondria scores were compared between the groups. RESULTS: The median ages of the study groups were 36 (26–59) and 40 (25–63) years, respectively (p=0.004). Both groups had similar body mass index, parity, menopausal status, and educational levels (p>0.05). When comparing the four subscales and the total score, the excessiveness (11 [3–15] vs. 9 [3–15], p<0.001, respectively) and the total CSS-12 score (31 [12–55] vs. 28 [12–49], p=0.002, respectively) were statistically significantly different between the two groups. CONCLUSIONS: In women with human papillomavirus 16/18 positivity undergoing colposcopy, cyberchondria levels were found to be significantly higher. Specifically, excessive information-seeking behavior significantly contributed to this elevated level of cyberchondria.
