Does neoadjuvant chemotherapy reduce surgical complexity in patients with advanced-stage epithelial ovarian cancer?

Abstract 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. Results One hundred and twenty-six patients with stage IIIC–IV ovarian cancer were included in the study. Primary cytoreductive surgery was performed in 67 patients, and interval cytoreductive surgery was performed in 59 patients after NACT. At least one complex surgery was performed in 74.6% of the patients in the primary cytoreductive surgery group and in 61% of the patients in the NACT group, with no statistically significant difference between the groups. However, the NACT group showed significantly decreased rates of low-rectal resection, diaphragmatic peritoneal stripping, and peritonectomy. Conclusions The analyses showed no reduction in the requirement for at least one complex surgical procedure in the group of patients who underwent NACT. Nevertheless, this group exhibited a significant decrease in low-rectal resection, diaphragmatic peritoneal stripping, and peritonectomy due to their effectiveness in reducing peritoneal disease.

High Grade Serous Ovarian Carcinoma in a Liver Transplant Recipient Patient: A Case Report and Review of Literature

According to GLOBOCAN 2020 data, the incidence of ovarian cancer is 1.6%. Ovarian cancer ranks 19th in incidence and 15th in mortality with a rate of 2.1%. High-grade serous ovarian cancer is the most common subtype of malignant ovarian tumors, and around 70% to 80% of all ovarian malignancies are included in this group. The incidence of gynecologic malignancies in liver transplant recipients is between 0% and 1.5%, and the duration of diagnosis for gynecologic cancer after transplantation is between 1 and 59 months. A 52-year-old patient was admitted to our hospital complaining of a periumbilical nodule. Her medical history revealed she had a cadaver liver transplantation in 2003 because of cirrhosis due to hepatitis B. On her physical examination, an erythematous nodular lesion was observed in the umbilical region. Ultrasonography demonstrated diffuse ascites and approximately 30 mm of a soft tissue density with lobulated contours located on the periumbilical skin. Both cytology and biopsy results were reported consistent with high-grade serous ovarian cancer. She underwent an operation, she had no problems during the postoperative follow-ups, and she was discharged on the eighth postoperative day. According to the 2018 International Federation of Gynecology and Obstetrics staging criteria for ovarian cancer, the patient's cancer was stage IVB. The patient received 6 cycles of adjuvant chemotherapy that included carboplatin (AUC = 6) and paclitaxel (175 mg/m

The effect of adjuvant radiotherapy on oncological outcomes in patients with early-stage cervical carcinoma with only intermediate-risk factors: a propensity score matching analysis

We aimed to evaluate whether adjuvant radiotherapy had a survival benefit for patients with early-stage cervical carcinoma with intermediate-risk factors. This study included patients who underwent radical hysterectomy and lymphadenectomy according to Wertheim-Okabayashi for stage IB1-IIA2 cervical carcinoma. Each patient had at least one intermediate-risk factor including tumour diameter ≥4 cm, deep stromal invasion, and positive lymphovascular space invasion (LVSI). Patients with lymph node metastasis, parametrial invasion, and positive surgical margins according to the final paraffin section were excluded. In total, 183 patients were included. Seventy-three (39.9%) patients had one, 85 (46.4%) had two, and 25 (13.7%) had three intermediate risk factors. Sixty-seven (36.6%) patients received adjuvant radiotherapy. There was a statistically significant difference in terms of stage, LVSI, and endometrial/uterine invasion between the groups that did and did not receive adjuvant radiotherapy (

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.
