Abstract

Aims: Preoperative tumor histologic evaluation plays a crucial role in determining the surgical and therapeutic approach for endometrial cancer. However, discrepancies between preoperative and postoperative histopathological findings are common, potentially affecting clinical management.
Methods: This retrospective study included 287 patients diagnosed with endometrial cancer at Bakırköy Maternity and Children Training and Research Hospital. All patients underwent preoperative fractional dilatation and curettage (D&C) followed by total abdominal hysterectomy with or without lymphadenectomy. Preoperative and postoperative pathology reports were compared to assess concordance in tumor grade and histological subtype. The correlation between grade agreement and myometrial invasion was also analyzed.
Results: The histologic type changed in 17.6% of cases between preoperative curettage and postoperative hysterectomy. The tumor grade was upgraded in 50.7% of grade 1 cases and 11.6% of grade 2 cases. The overall concordance between the preoperative and postoperative tumor grading was weak (kappa=0.292, p<0.001). The grade agreement was higher in cases with deep myometrial invasion (kappa=0.32) than in those with superficial invasion (kappa=0.24).
Conclusion: The substantial rate of discordance between preoperative and postoperative histologic findings highlights the limitations of D&C in accurately predicting tumor grade. Given the impact of tumor grading on surgical and adjuvant treatment decisions, multimodal preoperative assessment integrating imaging and molecular profiling may improve diagnostic accuracy and optimize treatment strategies for endometrial cancer.

Thanks

We would like to extend our deep appreciation to our hospital's pathologists, Dr. Cuneyt Ongut (in memoriam) and Dr. Adnan Erim, for their expertise and contributions to the histopathological evaluations in this study.

Endometriyal kanserde preoperatif ve postoperatif tümör derecesi: histolojik uyumluluk ve myometriyal invazyon ile ilişkisi

Abstract

Amaç: Preoperatif histolojik değerlendirme, endometriyal kanserin cerrahi ve tedavi stratejilerini belirlemede kritik bir rol oynar. Ancak, preoperatif ve postoperatif histopatolojik bulgular arasında uyumsuzluk sık görülmektedir ve bu durum klinik yönetimi etkileyebilir.

Yöntemler: Bu retrospektif çalışmaya, Bakırköy Kadın Doğum ve Çocuk Hastalıkları Eğitim ve Araştırma Hastanesi'nde endometriyal kanser tanısı almış 287 hasta dahil edildi. Tüm hastalara preoperatif fraksiyone dilatasyon ve küretaj (D&C) uygulandı ve ardından lenfadenektomi ile veya lenfadenektomi olmadan total abdominal histerektomi gerçekleştirildi. Preoperatif ve postoperatif patoloji raporları karşılaştırılarak tümör derecesi ve histolojik alt tipin uyumu değerlendirildi. Derece uyumu ile myometriyal invazyon arasındaki ilişki analiz edildi.

Bulgular: Preoperatif küretaj ve postoperatif histerektomi sonuçları arasında %17,6 oranında histolojik tip değişikliği gözlendi. Tümör derecesi, preoperatif Grade 1 vakaların %50,7’sinde ve Grade 2 vakaların %11,6’sında yükseltildi. Genel olarak preoperatif ve postoperatif tümör derecesi arasında zayıf bir uyum vardı (kappa = 0,292, p < 0,001). Derin myometriyal invazyonu olan vakalarda derece uyumu (kappa = 0,32), yüzeyel invazyonu olan vakalara (kappa = 0,24) kıyasla daha yüksek bulundu.

Sonuç: Preoperatif ve postoperatif histolojik bulgular arasındaki önemli düzeydeki uyumsuzluk, D&C’nin tümör derecesini doğru tahmin etmedeki sınırlamalarını vurgulamaktadır. Tümör derecesinin cerrahi kararları ve adjuvan tedavi seçimlerini etkileyen önemli bir faktör olduğu göz önüne alındığında, ileri görüntüleme teknikleri ve moleküler profilleme gibi multimodal preoperatif değerlendirme yaklaşımlarının kullanılması, tanısal doğruluğu artırarak tedavi stratejilerini optimize edebilir.
