Objective: To explore the clinical features and treatment of 22 patients with recurrent ovarian granulosa cell tumor (GCT). Methods: The clinical data of 22 females with recurrent ovarian GCT and received treatments in Qilu hospital were retrospectively analyzed. Results: During the recurrence interval, late recurrence (≥5 years) appeared in 14 patients, early recurrence (Conclusions: The intervals of GCT recurrence are usually long after the initial diagnosis. Continuous long-term follow-up is absolutely required, especially for those with early stage and complete surgery.

Background: Low-grade endometrial stromal sarcoma (LGESS) is the second most common malignant mesenchymal tumor of the uterus which usually affects young women. However, the researches on the safety and feasibility of the fertility-sparing management of it are limited. Methods: A retrospective analysis was performed including 5 women diagnosed with LGESS treated with fertility-sparing management at Qilu Hospital of Shandong University from 2010 to 2019. Besides that, 1,070 patients diagnosed with LGESS in SEER database from 1973 to 2016 were examined. By using the Kaplan–Meier method, survival curves were estimated, and comparisons of statistical significance were performed with the stratified log-rank test within each group. Results: Five patients with LGESS were enrolled in this study. All patients were submitted to fertility-sparing surgeries, after surgery, they all continued hormonal therapy for one year. Four out of the 5 patients recurred, to be more exact, 3 of them recurred in uterus and the other one in the uterus and iliac vascular region. They all suffered further surgery and all 5 patients were alive at the time of last contact. Besides, among these patients, two conceived naturally and delivered a healthy baby by cesarean section. Among 1,070 patients in SEER database, only 28 (2.6%) patients underwent local tumor excision, including excisional biopsy (39%), myomectomy (25%), laser ablation or excision (4%) and polypectomy (4%). There was no statistical significance was observed among TH±BSO, radical hysterectomy, subtotal hysterectomy and local tumor excision (P=0.29). Conclusions: Our analysis indicated that for those young LGESS patients who wish to preserve their fertility, the feasibility and safety of fertility-sparing management should be considered after gynecological oncologist and gynecological pathologist making professional decisions.

There is no consensus on the optimal chemotherapy regimen and the prognostic factors for ovarian large cell neuroendocrine carcinoma (LCNEC), a rare type of tumor. The objective of the present study is to present the case of a recent encounter of pure ovarian LCNEC and perform a brief review to summarize the clinicopathological features and prognostic factors of 57 cases of LCNEC patients that have been previously reported. Eligible studies were searched for online and 57 cases with clear follow-up data were found to have been reported. We present the 58th case, which is of a 70-year-old woman with stage IIIc primary pure LCNEC of the ovary. The initial symptom of this patient was abdominal distension (more than 2 months). A recent ultrasound test showed a solid-cystic mass occupying the pelvic and abdominal cavity. She received two courses of cisplatin-etoposide chemotherapy as an adjuvant therapy. No signs of nonclinical or radiological evidence of disease recurrence was found at follow-up examinations during the first 3 months after operation. A retrospective review of these 58 cases was conducted and survival curves were estimated. Using the Kaplan-Meier method. The patients included were aged between 18 and 80 years. A Kaplan-Meier survival curve revealed that the median overall survival was 10.000 months, while 26 (44.83%) patients died within 12 months. We compared the overall mean survival time of all patients with that of stage I patients (42.418 vs 42.047 months), which suggests that ovarian LCNEC has a very poor prognosis even at stage I. Mean survival was longer for patients who had undergone postoperative chemotherapy than for those without postoperative chemotherapy (48.082 vs 9.778 months). A small series, such as this, does not provide adequate data to establish a firm correlation between the postoperative chemotherapy and prognosis (p = 0.176). In our review of 58 cases with ovarian LCNEC, prognosis was unfavorable in most cases. Given the rarity of LCNEC, it is highly recommended that a global medical database of ovarian LCNEC and a standard system of diagnosis and treatment is established.

Curcumin (Cur), a yellow-colored dietary flavor from the plant (Curcuma longa), has been demonstrated to potentially resist diverse diseases, including ovarian cancer, but drug resistance becomes a major limitation of its success clinically. The key molecule or mechanism associated with curcumin resistance in ovarian cancer still remains unclear. The aim of our study was to investigate the effects of curcumin on autophagy in ovarian cancer cells and elucidate the underlying mechanism.
