Since the first days of organ transplantation, it has been accepted that solid transplant recipients have a high risk of developing cancer. Chronic immunosuppression and environmental factors play a role in cancer development in recipients. In the present study, we tried to evaluate the cumulative incidence of cervical dysplasia after renal transplantation, risk factors for disease development, and the time until high-grade dysplasia occurred. A total of 50 patients with renal transplantation who presented for gynecologic follow-up was included in the study. The medical records of the patients were reviewed until the last clinical visit, their demographic characteristics, transplant history, gynecologic history, and gynecologic examination results (cervical cytology and histology reports) were reviewed. Of the 50 women in the study population, 29 (58%; 95% confidence interval: 8.8-15.9) developed cervical dysplasia after the first transplant at a median follow-up of 7.8 (range: 4.6-12.9) years. Twenty-one women with benign cervical cytology before transplantation had evidence of low-grade intraepithelial lesions + after transplant (47% of these were within 2 years after transplant). During the follow-up, 8 women (18.2%) were diagnosed as having high-grade intraepithelial lesions + (within 5 years after transplantation). Renal transplant patients were found to have higher abnormal cervical cytology and histology rates than the normal population.

The coexistence of adenomyosis and cancer of the endometrium has attracted heightened scrutiny, leading to inquiries regarding their possible interactions and clinical ramifications. This study sought to assess the influence of adenomyosis on tumor features and survival outcomes in patients with endometrioid-type endometrial carcinoma. A retrospective cohort analysis was performed on 422 patients who underwent surgical intervention for endometrioid-type endometrial carcinoma. The cohort was categorized into two groups according to the presence or absence of adenomyosis. Clinical and pathological data were gathered and evaluated to compare tumor features and survival outcomes between the two cohorts. Adenomyosis was present in 144 (34.1%) patients. Patients in the adenomyosis group demonstrated significantly higher gravidity and parity compared to those without adenomyosis. Lymphovascular space invasion was detected in 8.3% of the adenomyosis group compared to 17.6% in the non-adenomyosis group (a 53% reduction, p = 0.010). Similarly, rates of myometrial invasion (81.3% vs. 65.5%, p = 0.001), cervical stromal invasion (9.0% vs. 14.1%, p = 0.005), and lymph node metastasis (4.2% vs. 14.4%, p = 0.001) were significantly lower in patients with adenomyosis. The five-year overall survival rate was 90.8% in the adenomyosis group and 87.1% in the non-adenomyosis group, although this difference was not statistically significant (p = 0.689). This study demonstrates that adenomyosis is associated with a significant reduction in aggressive tumor characteristics such as myometrial invasion, lymphovascular space involvement, and lymph node metastasis in patients with endometrioid-type endometrial cancer. These findings emphasize that adenomyosis may be a potential protective factor in endometrial cancer prognosis and should be considered in clinical risk assessment. Prospective studies with larger cohorts are needed to confirm the long-term effects of adenomyosis on survival.

Amaç: Bu çalışma, meme kanseri tedavisinde tamoksifen (TMX) kullanan kadınlarda endometrial hiperplastik değişiklikler, tamoksifen kullanım süresi ve anormal uterin kanama (AUB) arasındaki ilişkiyi araştırmayı amaçlamıştır. Gereç ve Yöntemler: Ocak 2019 ile Şubat 2024 arasında cerrahi işlemler geçiren 178 meme kanseri hastasının patoloji sonuçları üzerine retrospektif bir inceleme yapıldı. Hastalar iki gruba ayrıldı: TMX tedavisi alanlar (n=104) ve almayanlar (n=78). Endometrial patoloji sonuçları, yaş, parite, menopoz durumu, BMI, ultrasonografi bulguları ve AUB semptomları değerlendirildi. Bulgular: Tüm hastaların ortalama yaşı 49,7 yıldı. TMX grubunun ortalama yaşı ve BKI, non-TMX grubuna kıyasla anlamlı derecede daha düşüktü (p

Background and Objectives: The relationship between preoperative inflammatory markers and lymphovascular space invasion (LVSI) in endometrioid-type endometrial cancer (EC) remains incompletely defined and warrants evaluation using robust statistical methods. This study aimed to evaluate the independent association of preoperative inflammatory markers, analyzed strictly as continuous variables, with the presence of LVSI, and to develop a refined predictive nomogram adjusted for established clinical confounders. Materials and Methods: Data from 156 patients who underwent standard staging surgery for endometrioid-type EC were retrospectively analysed. To preserve statistical power and avoid structural artifacts from data forcing, preoperative glucose-to-lymphocyte ratio (GLR), platelet-to-lymphocyte ratio (PLR), and neutrophil-to-lymphocyte ratio (NLR) were modeled on their original continuous scale. Multivariable logistic regression analysis was performed to identify independent risk factors for LVSI, adjusting for patient age and maximum tumor diameter. Internal validation was conducted using bootstrap resampling (1000 iterations). Results: In the multivariable logistic regression model, continuous PLR emerged as a significant independent risk factor for the presence of LVSI (adjusted OR: 1.013 per 1-unit increase, 95% CI: 1.001–1.024; p = 0.033). Among clinical parameters, maximum tumor diameter demonstrated the strongest independent association with LVSI (adjusted OR: 1.595 per 1 cm increase, 95% CI: 1.211–2.099; p = 0.001). Continuous NLR (p = 0.513) and GLR (p = 0.545) did not retain statistical significance due to overlapping explanatory variance and shared hematological components. The optimized 3-variable nomogram (PLR, tumor size, and age) demonstrated an apparent C-index of 0.816 (95% bootstrap CI: 0.719–0.920) and a robust optimism-corrected C-index of 0.794. The bootstrap-corrected calibration slope was 0.909, and Decision Curve Analysis (DCA) demonstrated a positive net clinical benefit across clinically relevant threshold probabilities. Conclusions: Preoperative PLR, evaluated as a continuous parameter, provides a statistically stable framework for preoperative risk stratification in endometrioid EC. When integrated with tumor size and age, the proposed nomogram demonstrates promising discriminative performance and potential clinical utility pending external validation for predicting LVSI. However, given the limited number of LVSI-positive events (n = 17), these findings should be regarded as exploratory and hypothesis-generating and require external validation before clinical use.
