Objective: The primary objective of this study was to identify the risk of metastasis to lymph nodes above the inferior mesenteric artery (IMA) in endometrioid-type endometrial cancer (EC) and the factors that influence metastasis.

Methods: The study included patients who had been operated on for endometrioid-type EC in three gynecological oncology centers between 2007 and 2023. The supramesenteric lymph node (SM-LN) is the region between the left renal vein and the IMA, whereas the inframesenteric lymph node (IM-LN) is the region between the IMA and the aortic bifurcation, as determined by the level of the IMA.

Background: This study aimed to determine the effect of neoadjuvant chemotherapy (NACT) on the complex surgical procedures required in addition to staging surgery for the need to achieve a residual tumor 1 cm or less in a population of stage IIIC-IV epithelial ovarian cancer patients.

Methods: Patients were referred for NACT if preoperative imaging and/or intraoperative evaluation confirmed that it was not possible to achieve a residual tumor size of 1 cm or less with cytoreductive surgery or if the patient had a poor performance status and a high American Society of Anesthesiologists (ASA) score. Surgical complexity was defined as complex or non-complex.

Objective: We aimed to investigate differences between HPV-16 mono- and HPV-16/18 co-infections in terms of cervical dysplasia and invasive cancer.

Methods: This multicentre, retrospective study spanned from December 2017 to December 2020, involving women who visited gynaecological oncology clinics for colposcopy with either HPV-16 or HPV-16/18 positivity. A total of 736 patients, 670 in Group 1 (HPV-16 positivity) and 66 in Group 2 (HPV-16/18 positivity), were compared for the presence of CIN2+ lesions detected by colposcopic biopsy or endocervical curettage (ECC).

Background: This study aimed to evaluate the outcomes of patients diagnosed with stage IB2/IIA2 cervical squamous cell carcinoma who underwent neoadjuvant chemotherapy (NACT) prior to radical hysterectomy compared to those who did not receive NACT before surgery.

Materials And Methods: This is a multicenter study including data of 6 gynecological oncology departments. The study is approved from one of the institution's local ethics committee.

Objective: To determine whether patients with atypical squamous cells, cannot exclude high grade squamous intraepithelial neoplasia (ASC-H) cytology have a correlation between high-risk human papillomavirus (HPV) type and CIN 2+ lesion in final pathology.

Material And Methods: The study was conducted retrospectively, using data from three tertiary gynecologic oncology centers located in various regions of Turkey. Data from 5,271 patients who had colposcopy between January 2003 and January 2021 were analyzed.

Background: Medical treatment, expectant approaches, and surgical treatment options are available in the treatment of ectopic pregnancy. Regardless of the treatment, in addition to its effectiveness, the main concern is to limit the risk of relapse and preserve fertility.

Objectives: Determine the impact of medical or surgical treatment for ectopic pregnancy on future fertility.

Objective: To evaluate the clinicopathological characteristics of primary mucinous ovarian carcinoma (MOC) and define oncologic outcomes.

Material And Methods: This retrospective study reviewed patients diagnosed with primary MOC at a single institution and underwent primary treatment between 1990 and 2019. The clinicopathological factors affecting oncological outcomes and treatment response were evaluated.

Objective: To evaluate the oncologic outcomes of endometrial cancer metastasis to the adrenal gland and kidney, based on a case study and review of the literature.

Material And Methods: A systematic review of the medical literature was performed to identify articles about metastatic endometrial cancer to the adrenal gland and kidney from 1975 until 2021.

Results: A 55-year-old female patient was admitted to our center.

Objective: To investigate the clinicopathological features, prognostic factors, treatment, clinical response, and outcome of gestational choriocarcinoma (GCC).

Materials And Methods: A retrospective review was made of the clinicopathological and survival data of 13 patients who were diagnosed and treated for GCC in two referral centers in Turkey between 1992 and 2020.

Results: The median age of patients was 36 years (range, 27-54 years), and seven were ≤39 years.

Article Synopsis
  • The study focuses on analyzing Pap smear results that show atypical glandular cells, not otherwise specified (AGC-NOS), to identify potential cervical and endometrial lesions.
  • A total of 254 women who had AGC-NOS results and subsequently underwent colposcopy were reviewed, revealing that around 27.6% had premalignant or malignant lesions, including 6.7% with actual malignancies.
  • The findings suggest that careful evaluation of patients with AGC-NOS is crucial, with a recommendation for colposcopic examination and potential endometrial sampling to detect any underlying cancers.

In this retrospective study, patients with epithelial gynaecologic cancer with pulmonary recurrence (PR) were evaluated from five national gynaecologic oncology clinics. Patients with a diagnosis of primary endometrial, ovarian/fallopian tube/peritoneal, cervical or vaginal/vulvar tumours who developed an initial PR were included in the study A total of 122 patients were included in the study. The median follow-up time after recurrence was 7.

We investigated the association between preoperative ratios of inflammatory markers and the prognosis in patients with invasive cervical cancer (CC). In this single-centre study, we retrospectively enrolled 163 CC patients who underwent radical hysterectomy between February 2008 and October 2018. Among the evaluated ratios, a high neutrophil-to-lymphocyte ratio (N/L) was significantly associated with deep stromal invasion and tumour size larger than 2 cm, whereas a high M/L was significantly related to advanced-stage CC (IB3-IIIC2), lymphatic metastasis (total) and pelvic lymph node metastasis (= .

Article Synopsis
  • The study aimed to analyze the clinical and pathological characteristics, treatment methods, and outcomes for patients with malignant struma ovarii, using a systematic review of literature and a case study.
  • The research reviewed 178 cases and revealed that the overall survival rate was high at 91%, but factors like younger age and specific tumor characteristics were linked to poorer survival outcomes.
  • Radioactive iodine treatment before treatment failure significantly improved progression-free survival, highlighting the importance of tailored treatment strategies based on individual tumor histology and patient factors.
