Granulosa cell tumor resection with subsequent onset of rheumatoid arthritis.

Rheumatoid arthritis (RA) is an autoimmune disorder with an estrogen correlation. The disease can worsen or present with menopause. Granulosa cell tumors (GCT) are estrogen-secreting ovarian sex-cord stromal tumors with median incidence in the early postmenopausal years.

Risk of second primary cancers among survivors of gynecological cancers.

Objective: Survivors of gynecologic cancers have an increased risk of developing second primary cancers (SPC); however it is unclear which sites have higher risks. We aimed to ascertain risk of SPC among survivors of gynecological cancer, and identify anatomic sites at risk of SPC.

Methods: We queried the Surveillance, Epidemiology and End Results database (2000-2016) for confirmed cases of index gynecological (cervix uteri [cervical], corpus and uterus [endometrial], ovarian, vaginal, and vulvar) cancers.

Cisplatin-induced immune modulation in ovarian cancer mouse models with distinct inflammation profiles.

The backbone of ovarian cancer treatment is platinum-based chemotherapy and aggressive surgical debulking. New therapeutic approaches using immunotherapy via immune checkpoint blockade, which have demonstrated clinical efficacy in other tumor types, have been less promising in ovarian cancer. To increase their clinical efficacy, checkpoint inhibitors are now being tested in clinical trials in combination with chemotherapy.

Non-steroidal anti-inflammatory agents to induce regression and prevent the progression of cervical intraepithelial neoplasia.

Background: This is an updated version of the original Cochrane review published in 2014, Issue 4. Cervical intraepithelial neoplasia (CIN) precedes the development of invasive carcinoma of the cervix. Current treatment of CIN is quite effective, but there is morbidity for the patient related to pain, bleeding, infection, cervical stenosis and premature birth in a subsequent pregnancy.

Multiplex profiling identifies distinct local and systemic alterations during intraperitoneal chemotherapy for ovarian cancer: An NRG Oncology/Gynecologic Oncology Group Study.

Objectives: Ovarian cancer leads to abdominal carcinomatosis and late stage (III/IV) diagnosis in 75% of patients. Three randomized phase III trials have demonstrated that intraperitoneal (IP) chemotherapy improves outcomes in epithelial ovarian cancer. While IP treatment is validated by clinical trials, there is a poor understanding of the mechanism(s) leading to the survival advantage other than the increased concentration of cytotoxic drugs within the tumor microenvironment.

Anti-PD-L1 prolongs survival and triggers T cell but not humoral anti-tumor immune responses in a human MUC1-expressing preclinical ovarian cancer model.

Monoclonal antibodies that block inhibitory immune checkpoint molecules and enhance anti-tumor responses show clinical promise in advanced solid tumors. Most of the preliminary evidence on therapeutic efficacy of immune checkpoint blockers comes from studies in melanoma, lung and renal cancer. To test the in vivo potential of programmed death-ligand 1 (PD-L1) blockade in ovarian cancer, we recently generated a new transplantable tumor model using human mucin 1 (MUC1)-expressing 2F8 cells.

Non-steroidal anti-inflammatory agents to induce regression and prevent the progression of cervical intraepithelial neoplasia.

Background: Cervical intraepithelial neoplasia (CIN) precedes the development of invasive carcinoma of the cervix. Current treatment of CIN is quite effective, but there is morbidity for the patient related to pain, bleeding, infection, cervical stenosis and premature birth in subsequent pregnancy. Effective treatment with medications, rather than surgery, would be beneficial.

Isolated port-site metastasis after robotic hysterectomy for stage IA endometrial adenocarcinoma.

Background: Port-site metastasis is a known complication of laparoscopic surgery, although it has been described less in robotic surgery. There are limited reports of such occurrences in current literature.

Cases: Two patients underwent robotic-assisted total laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and lymph node dissection for stage IA endometrial cancer.

Short bowel syndrome causing bleeding diathesis and profound vitamin deficiency in pregnancy.

Background: Extensive bowel resection may lead to a state of inadequate nutrient absorption and malnutrition known as short bowel syndrome. Deficiencies in fat-soluble vitamins may occur from this condition, with sequelae such as a bleeding diathesis. Maternal vitamin deficiencies also have been associated with fetal anomalies.

Immunization of nonautoimmune mice with DNA binding domains of the largest subunit of RNA polymerase I results in production of anti-dsDNA and anti-Sm/RNP antibodies.

Antibodies against the N-terminal (NT) but not the basic domain (BD), DNA binding regions of the largest subunit (S1) of RNA polymerase I (RNAPI) were detected in the sera of MRL-lpr/lpr lupus mice. Antibodies against both RNAPI(S1)-NT and -BD, as well as other systemic lupus erythematosus (SLE) autoantigens (La, ribosomal P proteins and Sm/RNP) were produced by rabbits immunized with anti-DNA antibodies that had been affinity purified from SLE patients. Immunization of nonautoimmune mice (Balb/c) with RNAPI(S1)-NT, RNAPI(S1)-BD, or La in the form of GST fusion proteins, induced production of anti-double-stranded (ds) DNA and anti-Sm/RNP.
