    (2018) Sahin, Hanifi; Sari, Mustafa Erkan; Cuylan, Zeliha Firat; Haberal, Asuman Nihan; Sirvan, Levent; Coban, Gonca; Yalcin, Ibrahim; Gungor, Tayfun; Celik, Husnu; Meydanli, Mehmet Mutlu; Ayhan, Ali; https://orcid.org/0000-0001-9852-9911; https://orcid.org/0000-0002-3285-5519; AAJ-5802-2021; 29383437; AAK-4587-2021; AAI-9974-2021; AAL-1923-2021
    The purpose of this study was to compare the prognoses of women with pure ovarian clear cell carcinoma (OCCC) arising from endometriosis to those of women with pure OCCC not arising from endometriosis treated in the same manner. A dual-institutional, retrospective database review was performed to identify patients with pure OCCC who were treated with maximal or optimal cytoreductive surgery (CRS) followed by paclitaxel/carboplatin chemotherapy between January 2006 and December 2016. Patients were divided into two groups according to the detection of cancer arising in endometriosis or not, on the basis of pathological findings. Demographic, clinicopathological, and survival data were collected, and prognosis was compared between the two groups. Ninety-three women who met the inclusion criteria were included. Of these patients, 48 (51.6%) were diagnosed with OCCC arising in endometriosis, while 45 (48.4%) had no concomitant endometriosis. OCCC arising in endometriosis was found more frequently in younger women and had a higher incidence of early stage disease when compared to OCCC patients without endometriosis. The 5-year overall survival (OS) rate of the patients with OCCC arising in endometriosis was found to be significantly longer than that of women who had OCCC without endometriosis (74.1 vs. 46.4%; p = 0.003). Although univariate analysis revealed the absence of endometriosis (p = 0.003) as a prognostic factor for decreased OS, the extent of CRS was identified as an independent prognostic factor for both recurrence-free survival (hazard ratio (HR) 8.7, 95% confidence interval (CI) 3.15-24.38; p < 0.001) and OS (HR 11.7, 95% CI 3.68-33.71; p < 0.001) on multivariate analysis. Our results suggest that endometriosis per se does not seem to affect the prognosis of pure OCCC.

    Background. Up to 26% of patients with early-stage cervical cancer experience relapse after primary surgery. However, little is known about which factors influence prognosis following disease recurrence. Therefore, our aims were to determine post-recurrence disease-specific survival (PR-DSS) and to identify respective prognostic factors for PR-DSS. Methods. Data from 528 patients with early-stage cervical cancer who relapsed after primary surgery performed between 2007 and 2016 were obtained from the SCANN study (Surveillance in Cervical CANcer). Factors related to the primary disease and recurrence were combined in a multivariable Cox proportional hazards model to predict PR-DSS. Results. The 5-year PR-DSS was 39.1% (95% confidence interval [CI] 22.7%-44.5%), median disease-free interval between primary surgery and recurrence (DFI1) was 1.5 years, and median survival after recurrence was 2.5 years. Six significant variables were identified in the multivariable analysis and were used to construct the prognostic model. Two were related to primary treatment (largest tumour size and lymphovascular space invasion) and four to recurrence (DFI1, age at recurrence, presence of symptoms, and recurrence type). The C-statistic after 10-fold cross-validation of prognostic model reached 0.701 (95% CI 0.675-0.727). Three risk-groups with significantly differing prognoses were identified, with 5-year PR-DSS rates of 81.8%, 44.6%, and 12.7%. Conclusions. We developed the robust model of PR-DSS to stratify patients with relapsed cervical cancer according to risk profiles using six routinely recorded prognostic markers. The model can be utilised in clinical practice to aid decision-making on the strategy of recurrence management, and to better inform the patients.

    Does lymph node ratio have any prognostic significance in maximally cytoreduced node-positive low-grade serous ovarian carcinoma?
    (2020) Aslan, Koray; Meydanli, Mehmet Mutlu; Akilli, Huseyin; Durmus, Yasin; Gokcu, Mehmet; Kayikcioglu, Fulya; Demirkiran, Fuat; Ayhan, Ali; 0000-0002-5404-0118; 32409929; AAP-6729-2021; AAJ-5802-2021
    Purpose To determine the prognostic impact of the lymph node ratio (LNR) in node-positive low-grade serous ovarian cancer (LGSOC). Methods We retrospectively reviewed women with LGSOC who had undergone maximal cytoreduction followed by standard chemotherapy in 11 centers from Turkey during a study period of 20 years. Sixty two women with node-positive LGSOC were identified. LNR was defined as the number of metastatic lymph nodes (LNs) divided by the number of total LNs removed. We grouped patients pursuant to the LNR as LNR <= 0.09 and LNR > 0.09. The prognostic value of LNR was investigated by employing the univariate log-rank test and multivariate Cox-regression model. Results With a median follow-up of 45 months, the 5-year progression-free survival (PFS) rates were 61.7% for women with LNR <= 0.09 and 32.0% for those with LNR > 0.09 (p = 0.046) whereas, the 5-year overall survival (OS) rates were 72.8% for LNR <= 0.09 and 54.7% for LNR > 0.09 (p = 0.043). On multivariate analyses, lymphovascular space invasion (LVSI) (Hazard Ratio [HR] 4.18, 95% confidence interval [CI] 1.88-9.27; p < 0.001), omental involvement (HR 3.48, 95% CI 1.36-8.84; p = 0.009) and LNR > 0.09 (HR 3.51, 95% CI 1.54-8.03; p = 0.003) were adverse prognostic factors for PFS. Additionally, LVSI (HR 6.56, 95% CI 2.33-18.41; p < 0.001), omental involvement (HR 6.34, 95% CI 1.86-21.57; p = 0.003) and LNR > 0.09 (HR 7.20, 95% CI 2.33-22.26; p = 0.001) were independent prognostic factors for decreased OS. Conclusion LNR > 0.09 seems to be an independent prognosticator for decreased survival outcomes in LGSOC patients who received maximal cytoreduction followed by standard adjuvant chemotherapy.
