A phase 2 feasibility study of nab-paclitaxel and carboplatin in epithelial carcinoma of the uterus.

Background: We evaluated the feasibility of completing 6 cycles of nab-paclitaxel (nab-P) and carboplatin (C) in a single arm prospective clinical trial for advanced/recurrent EC and safety and efficacy of day (D) 1, 8 nab-P in combination with D1 C q3weeks.

Methods: Patients with early-stage, high-risk, advanced primary/recurrent EC without prior platinum/taxane exposure were enrolled in an open-label, single-institution trial (NCT02744898). Patients received 6 cycles of D1 nab-P 100 mg/m IV with C AUC 6 IV and D8 nab-P 100 mg/m IV q21D.

History of intraperitoneal platinum drug delivery for ovarian cancer and its future applications.

Intraperitoneal (IP) delivery of cisplatin was developed in the 1970s based on a strong pharmacologic rationale and rodent models. Its advantage over intravenous (IV) administration was supported initially by observational studies in treating recurrent ovarian cancer and eventually by better outcomes from IP IV cisplatin in randomized studies in patients undergoing optimal surgical debulking at diagnosis. In the past two decades, with the introduction of novel anticancer interventions (such as taxanes, bevacizumab, inhibitors of DNA repair, and immune check point inhibitors), advantages of IP drug delivery are less clear and concerns are raised on cisplatin's therapeutic index.

Breast cancer incidence in BRCA mutation carriers with ovarian cancer: A longitudal observational study.

Objectives: We evaluated the incidence of breast cancer and overall survival in a multi-center cohort of ovarian cancer patients carrying BRCA1/2 mutations in order to assess risks and formulate optimal preventive interventions and/or surveillance.

Methods: Medical records of 502 BRCA1/2 mutation carriers diagnosed with ovarian cancer between 2000 and 2018 at 7 medical centers in Israel and one in New York were retrospectively analyzed for breast cancer diagnosis. Data included demographics, type of BRCA mutations, surveillance methods, timing of breast cancer diagnosis, and family history of cancer.

Weekly Carboplatin and Paclitaxel for Ovarian Cancer: The "Finer Points".

First‐line ovarian cancer platinum doublet is paclitaxel‐carboplatin. Superiority of weekly paclitaxel schedules has not been confirmed; however, a novel schedule with both drugs given weekly (days 1, 8, 15) followed by a 2‐week break may be advantageous to some.

Sequential therapy with INCAGN01949 followed by ipilimumab and nivolumab in two patients with advanced ovarian carcinoma.

Agonists of the co-stimulatory molecule OX40 (CD134) are in clinical assessment alone and in combination with other immunotherapies. Recent pre-clinical studies have suggested that concurrent administration of OX40 agonists with anti-PD1 therapy is detrimental to the efficacy of such combinations and maximal efficacy may require sequential administration of the OX40 agonist followed by anti-PD1 therapy. In this report, we detail two patients with advanced ovarian carcinoma were treated with INCAGN01949, an agonistic OX40 Ab, as part of a clinical trial until disease progression.

Temporal trends of subsequent breast cancer among women with ovarian cancer: a population-based study.

Purpose: To examine trends, characteristics and outcomes of women who develop both ovarian and breast cancers.

Methods: This is a retrospective study examining the Surveillance, Epidemiology, and End Results Program from 1973 to 2013. Among ovarian cancer (n = 133,149) and breast cancer (n = 1,143,219) cohorts, women with both diagnoses were identified and temporal trends, tumor characteristics and survival were examined.

Phase I and pharmacokinetic study of veliparib, a PARP inhibitor, and pegylated liposomal doxorubicin (PLD) in recurrent gynecologic cancer and triple negative breast cancer with long-term follow-up.

Objective: Poly(ADP-ribosyl) polymerases (PARPs) are nuclear enzymes with roles in DNA damage recognition and repair. PARP1 inhibition enhances the effects of DNA-damaging agents like doxorubicin. We sought to determine the recommended phase two dose (RP2D) of veliparib with pegylated liposomal doxorubicin (PLD) in breast and recurrent gynecologic cancer patients.

Oral Squamous Cell Carcinoma as a Complication of Treatment for Recurrent High-Grade Serous Cancer.

Objectives/hypothesis: Advances in cancer treatment have increased survival for many patients, prompting a need for greater recognition of the long-term complications of treatment. Chemotherapy agents have the potential to induce carcinogenesis and can increase the risk of secondary malignancy. Pegylated liposomal doxorubicin (PLD) used for maintenance treatment of recurrent high-grade serous cancers has been associated with the development of oral cavity squamous cell carcinoma (SCC).

PARP inhibitors: clinical development, emerging differences, and the current therapeutic issues.

Following years in development, poly-adenosyl-ribose polymerase (PARP) inhibitors continue to advance the treatment of ovarian and breast cancers, particularly in patients with pathogenic mutations. Differences in clinical trial design have contributed to distinct indications for each of the PARP inhibitors. Toxicity patterns are also emerging that suggest agents differ in their normal tissue tolerance - beyond what might be expected by dose variations and/or exposure to prior treatment.

Decreasing Trends of Secondary Primary Colorectal Cancer among Women with Uterine Cancer: A Population-Based Analysis.

The current study examined trends, characteristics, and outcomes of women with uterine cancer who had secondary colorectal cancer. This is a retrospective study utilizing the Surveillance, Epidemiology, and End Results Program between 1973-2013. Among uterine cancer ( = 246,272) and colorectal cancer ( = 421,312) cohorts, women with both diagnoses were identified, and clinico-pathological factors and survival were extracted and analyzed.

Decreasing secondary primary uterine cancer after breast cancer: A population-based analysis.

Objective: To report population-based statistics of women with uterine cancer and a history of prior breast cancer.

Methods: This is a retrospective study examining the Surveillance, Epidemiology, and End Results Program between 1973 and 2013. Temporal trends, clinico-pathological characteristics, and survival of women with uterine cancer who had prior breast cancer were assessed.

Neoadjuvant chemotherapy in patients with advanced endometrial cancer.

Objectives: Neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) is a treatment strategy for ovarian cancer patients with unresectable disease or poor performance status (PS). This strategy has been used in the treatment of advanced endometrial cancer and a survival benefit has been shown in patients who are subsequently able to undergo interval cytoreduction. This study sought to review our single institution experience with NACT for advanced endometrial cancer.

Women's cancers: how the discovery of BRCA genes is driving current concepts of cancer biology and therapeutics.

Over the last two decades, discoveries related to the breast cancer susceptibility genes 1 and 2 ( and ) have profoundly changed our understanding and management of hereditary breast and ovarian cancers. The concept of synthetic lethality, which arises when cells become vulnerable to a combination of deficiencies in DNA repair, has driven the expanding roles of poly (adenosine diphosphate (ADP)-ribose) polymerase inhibitors in breast and ovarian cancers, and prevention strategies are taking into account the tissue specificity, natural history (fallopian tube origin of some high-grade serous ovarian cancers) and hormone sensitivity of BRCA-associated cancers. Current research has focussed on further elucidating the roles of BRCA proteins in DNA repair, investigating other key DNA repair processes and proteins and linking aberrant DNA repair with carcinogenesis.

Efficacy of pegylated liposomal doxorubicin maintenance therapy in platinum-sensitive recurrent epithelial ovarian cancer: a retrospective study.

Objective: To examine the effectiveness of pegylated liposomal doxorubicin (PLD) maintenance therapy (intravenous administration at dose 40 mg/m on day 1, repeated every 4 weeks) after first-line salvage chemotherapy for platinum-sensitive recurrent epithelial ovarian cancer.

Methods: This retrospective cohort study examined women with a first recurrence of platinum-sensitive epithelial ovarian cancer diagnosed between 2005 and 2015. Eligible cases had PLD maintenance following the first-line salvage chemotherapy (n = 28).

Nomogram for Predicting Individual Survival After Recurrence of Advanced-Stage, High-Grade Ovarian Carcinoma.

Objective: To analyze clinical prognostic factors for survival after recurrence of high-grade, advanced-stage ovarian-peritoneal-tubal carcinoma and to develop a nomogram to predict individual survival after recurrence.

Methods: We retrospectively analyzed patients treated in multicenter Gynecologic Oncology Group protocols for stage III and IV ovarian-peritoneal-tubal carcinoma who underwent primary debulking surgery, received chemotherapy with paclitaxel and a platinum compound, and subsequently developed recurrence. Prognostic factors affecting survival were identified and used to develop a nomogram, which was both internally and externally validated.

Carboplatin/Paclitaxel Induction in Ovarian Cancer: The Finer Points.

The carboplatin/paclitaxel doublet remains the chemotherapy backbone for the initial treatment of ovarian cancer. This two-drug regimen, with carboplatin dosed using the Calvert formula, yielded convincing noninferior outcomes when compared with the prior, more toxic, regimen of cisplatin/paclitaxel. Carboplatin's dose-limiting toxicity is thrombocytopenia; however, when this drug is properly dosed and combined with paclitaxel, the doublet's cycle 1 dose in chemotherapy-naive women is generally safe.

Lasting pathologic complete response to chemotherapy for ovarian cancer after receiving antimalarials for dermatomyositis.

Could hydroxychloroquine and quinacrine antimalarial therapy for dermatomyositis later attributed to a paraneoplasic manifestation of an ovarian cancer enhance its subsequent response to chemotherapy? Five months after being diagnosed with dermatomyositis, while somewhat improved with hydroxychloroquine, quinacrine and methotrexate, this 63-year-old woman presented with an advanced intra-abdominal epithelial ovarian cancer documented (but not resected) at laparotomy. Neoadjuvant carboplatin/paclitaxel resulted in remarkable improvement of symptoms, tumour markers and imaging findings leading to thorough cytoreductive surgery at completion of five cycles. No tumour was found in the resected omentum, gynaecologic organs, as well as hepatic and nodal sampling thus documenting a complete pathologic response; a subcutaneous port and an intraperitoneal (IP) catheter were placed for two cycles of IP cisplatin consolidation.

Timing is everything: intraperitoneal chemotherapy after primary or interval debulking surgery for advanced ovarian cancer.

Purpose: To evaluate the outcomes of intraperitoneal chemotherapy (IP) compared with those of intravenous chemotherapy (IV) in patients with advanced ovarian cancer after neoadjuvant chemotherapy (NACT) and interval debulking surgery (IDS) or primary debulking surgery (PDS).

Methods: Patients with advanced epithelial ovarian carcinoma treated with PDS or NACT and IDS from 2006 to 2015 were identified. Comparative statistics were used to evaluate covariates, and survival rates were calculated using the Kaplan-Meier method and compared with log-rank tests.

Carboplatin (every 21 days) and divided-dose paclitaxel (days 1, 11): rationale and tolerance in chemotherapy naïve women with high-grade epithelial cancers of Mullerian origin.

Purpose: We report here on the tolerance of a carboplatin-'divided dose' paclitaxel (given on days 1 and 11) regimen in chemotherapy-naïve patients with resected and staged endometrial epithelial neoplasms deemed at high-risk of recurrence or early stage epithelial high-grade serous tubo-ovarian adenocarcinomas after risk-reducing surgery. More recently, we applied this regimen as neoadjuvant chemotherapy for advanced ovarian cancer presentations.

Methods: A retrospective chart review of patients receiving this day 1, 11 paclitaxel regimens in combination with carboplatin at AUC 6 every 3 weeks since 2004 was carried out by the second author with subsequent updates by the first and third authors.

Serial immunological parameters in a phase II trial of exemestane and low-dose oral cyclophosphamide in advanced hormone receptor-positive breast cancer.

Background And Purpose: Resistance to endocrine therapies in hormone receptor (HR)-positive breast cancer is a significant challenge. Prior studies have shown that low-dose oral cyclophosphamide can transiently deplete regulatory T cells (Tregs) and improve anti-tumor immunity. We investigated the combination of exemestane with cyclophosphamide in patients with advanced HR-positive breast cancer and assessed changes in circulating immune cell subsets.

An evaluation of progression free survival and overall survival of ovarian cancer patients with clear cell carcinoma versus serous carcinoma treated with platinum therapy: An NRG Oncology/Gynecologic Oncology Group experience.

Purpose: We examined disparities in prognosis between patients with ovarian clear cell carcinoma (OCCC) and serous epithelial ovarian cancer (SOC).

Methods: We reviewed data from FIGO stage I-IV epithelial ovarian cancer patients who participated in 12 prospective randomized GOG protocols. Proportional hazards models were used to compare progression-free survival (PFS) and overall survival (OS) by cell type (clear cell versus serous).

Phase II study of irinotecan in combination with bevacizumab in recurrent ovarian cancer.

Objectives: To evaluate the efficacy and safety of irinotecan and bevacizumab in recurrent ovarian cancer. The primary objective was to estimate the progression free survival (PFS) rate at 6months. Secondary objectives included estimation of overall survival (OS), objective response rate (ORR), duration of response, and an evaluation of toxicity.
