Histone deacetylase inhibitor, panobinostat, exerts anti-proliferative effect with partial normalization from aberrant epigenetic states on granulosa cell tumor cell lines.

The prognosis of the patients with inoperable or advanced granulosa cell tumors (GCTs) is still poor, and therefore it is important to establish a novel treatment strategy. Here we investigated the in vitro effects of a histone deacetylase inhibitor, panobinostat (PS) on two GCT cell lines (KGN and COV434). GCT cell lines were found to be susceptible to PS treatment and it inhibited cell growth mainly by apoptosis.

Does local infiltration anesthesia on laparoscopic surgical wounds reduce postoperative pain? Randomized control study.

Purpose: Recently, endoscopic surgeries are widely performed in the gynecological field. Several studies on the use of local anesthesia for pain control after laparoscopic surgery have been conducted; however, its effects remain controversial. Herein, a randomized control study on gynecological laparoscopic surgeries was conducted to analyze the effectiveness of local anesthesia on postoperative pain.

[A Case Report of Surgery and Chemotherapy for a Patient with Rapidly Progressing Breast Cancer during Pregnancy].

A 33-year-old woman became aware of a right breast mass at her 28th week of pregnancy. From the biopsy results, we diagnosed her with right breast cancer. At her 33rd week of pregnancy, she underwent modified radical mastectomy (pT2N3aM0, Stage III C, ER-negative, PR-negative, HER2-positive), and she elected to receive adjuvant therapy after the surgery during her pregnancy.

The Analysis of Cell Cycle-related Proteins in Ovarian Clear Cell Carcinoma Versus High-grade Serous Carcinoma.

In Japan, the frequency of ovarian clear cell carcinoma (CCC) is twice as high as that in the United States and Europe. Often, patient prognosis with CCC is poor because of chemoresistance. Here, we focus on the cell cycle, which is one of the mechanisms of chemoresistance.
