Spotlight on oncologic outcomes and prognostic factors of pure endometrioid ovarian carcinoma

To determine the prognostic factors related to recurrence and survival, and to evaluate the need for adjuvant chemotherapy in patients with endometrioid type epithelial ovarian cancer (EEOC). This study included 63 EEOC patients who were surgically staged. The FIGO 2014 stage was stage I in 41 (65 %) patients, stage II in 8 (12.5 %) patients, stage III in 14 (22.5 %) patients. 5-year failure-free survival (FFS) was 78 % in the entire cohort. 15 (23.8 %) patients had disease failure. In univariate analysis, advanced stage (II&III), high grade tumor, presence of ascites, bilateral tumor, presence of omental metastasis, positive peritoneal cytology were prognostic factors for poor FFS. Only the stage was determined to be an independent prognostic factor for disease-failure. According to multivariate analysis, stage II&III was related to a statistically significant hazard ratio for a disease failure of 3.49 (95 % confidence interval: 1.029-11.841; p = 0.045). The effectiveness of adjuvant chemotherapy was assessed for 41 patients with stage I. Eleven (26.8 %) patients with stage I did not receive adjuvant chemotherapy. Whereas 5-year FFS was 88 % in patients receiving adjuvant chemotherapy, that was 91 % in patients without adjuvant chemotherapy (p = 0.923). The independent prognostic factor for recurrence in EEOC was stage only. Adjuvant chemotherapy was not related to improvement in FFS in the early stage EEOC that were completely staged.

Primary leiomyosarcoma of the uterine cervix: report of 4 cases, systematic review, and meta-analysis

Background: Primary cervical leiomyosarcomas (CLMS) constitute 21% of all cervical sarcomas. Because of their rarity, to our knowledge, fewer than 40 cases have been reported. The aim of this study is to evaluate the clinical and surgical–pathological features, prognosis, treatment options, and survival of primary CLMS. Methods: A systematic review of the medical literature was conducted to evaluate articles about primary CLMS. The literature was searched between 1959 and May 2019. On final evaluation, there were 29 articles (one consisted of 8 cases; one consisted of 3 cases) and 42 cases with the addition of our 4 cases. Results: Age (⩾48 versus ⩽47 years) (hazard ratio.HR], 4.528; 95% confidence interval.CI], 1.550–13.227; p=0.006) and mitoses count (<10/10 high-power field [HPF] versus ⩾10/10 HPF) (HR, 3.865; 95% CI, 1.046–14.278; p=0.043) are independent prognostic factors for recurrence and age (HR, 5.318; 95% CI, 1.671–16.920; p=0.005) and hysterectomy (performed versus not performed) (HR, 4.377; 95% CI, 1.341–14.283; p=0.014) are independent prognostic factors for death because of disease on multivariate analysis. Conclusions: Information on primary CLMS is sparse and obtained from rare case reports and case series. Hysterectomy must be the first choice of treatment in these patients according to our results on multivariate analysis. The type of hysterectomy does not have an effect on oncologic outcome. Radical hysterectomy is not obligatory and more data are needed to make more accurate conclusions.

The prognostic factors in 384 patients with FIGO 2014 stage IB cervical cancer: What is the role of tumor size on prognosis?

To define the relationship of tumor size with surgico-pathological factors and oncological outcome in FIGO 2014 stage IB cervical cancer. This study retrospectively evaluated 384 FIGO 2014 Stage IB cervical cancer patients who underwent radical hysterectomy and lymphadenectomy. Tumor size was stratified according to 2 cm (≤ 2cm, 2-≤4 cm, >4 cm) and 4 cm (≤4 cm, >4 cm), and the relationship with poor prognostic factors, and the effects on survival were examined. The distribution of prognostic factors was compared between three subgroups: ≤2 cm vs. 2-≤4 cm; 2-≤4 cm vs. > 4 cm and ≤ 2 cm vs. > 4 cm. Survival rate was evaluated using the Kaplan-Meier method and compared with the log-rank test. Multivariate analysis was performed using Cox proportional-hazards regression. Stratification of tumor size according to 4 cm was found to better determine pelvic lymph node determination. Parametrial involvement, uterine involvement and deep cervical stromal invasion were correlated with increasing tumor size. Lymph node involvement and uterine involvement were an independent prognostic risk factor for recurrence and cancer-specific survival. Tumor size showed no association with prognosis. There is no meaningful cut-off value for tumor size determining all surgico-pathological factors. There was also seen to be no association between tumor size and recurrence or disease-related mortality.

Recurrence pattern and prognostic factors for survival in cervical cancer with lymph node metastasis

AbstractAimThe aim of this study is to evaluate the recurrence pattern and oncological outcomes in cervical cancer (CC) patients with lymph node metastasis.MethodsThis study included 224 International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IB1‐IIIB CC patients with pathologically proven lymph node metastasis. Surgical intervention was grouped as hysterectomy performed/not performed. Adjuvant therapy decision was made by the tumor board. Radiotherapy was applied to all patients with lymph node metastasis.ResultsOnly paraaortic lymph node metastasis was determined as an independent prognostic factor for recurrence. Presence of paraaortic lymph node metastasis increased the risk of recurrence more than two times (odds ratio: 2.129; 95% confidence interval: 1.011–4.485; p = 0.047). An independent prognostic factor for death because of disease was age only. Risk of death was nearly doubled with younger age (odds ratio: 2.693; 95% confidence interval: 1.064–6.184; p = 0.037).ConclusionThe most of recurrences were located at distant sites and multiple regions. Paraaortic lymph node metastasis was the only independent prognostic factor for recurrence, in spite of that age was an independent predictor for risk of death in patients with early stage or locally advanced CC and also with surgically proven metastatic lymph nodes. Furthermore, the presence of the paraaortic lymph node metastasis was significantly associated with distant recurrence. Therefore, more appropriate and individualized therapy strategy focusing on intenser systemic chemotherapy options in addition to radiotherapy should be taken into consideration according to paraaortic lymph node metastasis and age.

Oncologic outcome in patients with 2018 FIGO stage IB cervical cancer: Is tumor size important?

AbstractBackgroundTo evaluate the prognostic factors and oncologic outcome in patients with 2018 International Federation of Gynecology and Obstetrics (FIGO) stage IB cervical cancer (CC) after radical hysterectomy and lymphadenectomy.Materials and MethodsThis study included 290 patients with type II or III radical hysterectomy + pelvic ± para‐aortic lymphadenectomy and 2018 FIGO stage IB1‐3 epithelial CC. Disease‐free survival (DFS) estimates were determinate by using the Kaplan–Meier method. Survival curves were compared using the log‐rank test. Multivariate analysis was performed using a Cox proportional hazards models.ResultsThe mean age of study cohort was 52 ± 10.25 years. Five‐year DFS was 93% in entire cohort. On univariate analysis, surgical border involvement (p = 0.007), lymphovascular space invasion (LVSI) (p = 0.040), uterine involvement (p = 0.040), and depth of cervical stromal invasion (p = 0.007) were found to have statistical significance for DFS. However, none of them were independent prognostic factors for the risk of recurrence. Tumor size according to 2018 FIGO staging criteria was not related with recurrence.ConclusionsSurgical border involvement, LVSI, depth of cervical stromal invasion, and uterine involvement were predictors for DFS on univariate analysis. Tumor size was not predicting to recurrence in patient with 2018 FIGO stage IB1‐3 CC.

Surgery for patients with endometrioid-type endometrial cancer: is lymphadenectomy above the inferior mesenteric artery necessary?

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. 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. The study sample comprised 412 patients. The median number of lymph nodes excised per patient was 58. The median count was 37 for pelvic lymph nodes, 21 for para-aortic lymph nodes, 8 for IM-LN, and 13 for SM-LN. In the univariate analysis, the factors that were found to be statistically significant in determining SM-LN metastasis included tumor size, depth of myometrial invasion, uterine serosal invasion, lymphovascular space invasion (LVSI), cervical invasion, peritoneal cytology, adnexal metastasis, omental metastasis, non-nodal extrauterine metastasis, pelvic lymph node metastasis, and IM-LN metastasis. In the multivariate analysis, SM-LN metastasis was independently associated with tumor size, LVSI, pelvic lymph node metastasis, and IM-LN metastasis. In conclusion, in cases of intermediate-high risk EC, it is important to know that the disease spreads to SM-LN in 7.3% of patients. The efficacy of postoperative adjuvant treatment may be inadequate due to a lack of information regarding the SM-LN region.

Defining the relationship between ovarian adult granulosa cell tumors and synchronous endometrial pathology: Does ovarian tumor size correlate with endometrial cancer?

Abstract Objective The main feature of adult granulosa cell tumors (AGCT) is their capacity to secrete hormones, with nearly all of them capable of synthesizing oestradiol. The primary goal of this study is to identify synchronized endometrial pathologies, particularly endometrial cancer, in AGCT patients who had undergone a hysterectomy. Materials and Methods The study cohort comprised retrospectively of 316 AGCT patients from 10 tertiary gynecological oncology centers. AGCT surgery consisted of bilateral salpingo‐oophorectomy, hysterectomy, peritoneal cytology, omentectomy, and the excision of any suspicious lesion. The median tumor size value was used to define the relationship between tumor size and endometrial cancer. The relationship between each value and endometrial cancer was evaluated. Results Endometrial intraepithelial neoplasia, or hyperplasia with complex atypia, was detected in 7.3% of patients, and endometrial cancer in 3.1% of patients. Age, menopausal status, tumor size, International Federation of Gynecology and Obstetrics stage, ascites, and CA‐125 level were not statistically significant factors to predict endometrial cancer. There was no endometrial cancer under the age of 40, and 97.8% of women diagnosed with endometrial hyperplasia were over the age of 40. During the menopausal period, the endometrial cancer risk was 4.5%. Developing endometrial cancer increased to 12.1% from 3.2% when the size of the tumor was >150 mm in menopausal patients ( p  = 0.036). Conclusion Endometrial hyperplasia, or cancer, occurs in approximately 30% of AGCT patients. Patients diagnosed with AGCT, especially those older than 40 years, should be evaluated for endometrial pathologies. There may be a relationship between tumor size and endometrial cancer, especially in menopausal patients.

Prognostic factors of adult granulosa cell tumors of the ovary: a Turkish retrospective multicenter study

To define the clinical, histopathological features and the prognostic factors affecting survival in patients with adult granulosa cell tumors of the ovary (AGCT). A 322 patients whose final pathologic outcome was AGCT treated at nine tertiary oncology centers between 1988 and 2021 participated in the study. The mean age of the patients was 51.3±11.8 years and ranged from 21 to 82 years. According to the International Federation of Gynecology and Obstetrics 2014, 250 (77.6%) patients were stage I, 24 (7.5%) patients were stage II, 20 (6.2%) patients were stage III, and 3 (7.8%) were stage IV. Lymphadenectomy was added to the surgical procedure in 210 (65.2%) patients. Lymph node involvement was noted in seven (3.3%) patients. Peritoneal cytology was positive in 19 (5.9%) patients, and 13 (4%) had metastases in the omentum. Of 285 patients who underwent hysterectomy, 19 (6.7%) had complex hyperplasia with atypia/endometrial intraepithelial neoplasia, and 8 (2.8%) had grade 1 endometrioid endometrial carcinoma. It was found that 93 (28.9%) patients in the study group received adjuvant treatment. Bleomycin, etoposide, cisplatin was the most commonly used chemotherapy protocol. The median follow-up time of the study group was 41 months (range, 1-276 months). It was noted that 34 (10.6%) patients relapsed during this period, and 9 (2.8%) patients died because of the disease. The entire cohort had a 5-year disease-free survival (DFS) of 86% and a 5-year disease-specific survival of 98%. Recurrences were observed only in the pelvis in 13 patients and the extra-abdominal region in 7 patients. The recurrence rate increased 6.168-fold in patients with positive peritoneal cytology (95% confidence interval [CI]=1.914-19.878; p=0.002), 3.755-fold in stage II-IV (95% CI=1.275-11.063; p=0.016), and 2.517-fold in postmenopausal women (95% CI=1.017-6.233; p=0.046) increased. In this study, lymph node involvement was detected in 3.3% of patients with AGCT. Therefore, it was concluded that lymphadenectomy can be avoided in primary surgical treatment. Positive peritoneal cytology, stage, and menopausal status were independent prognostic predictors of DFS.
