A phase II study of neoadjuvant liposomal irinotecan with 5-FU and oxaliplatin (NALIRIFOX) in pancreatic adenocarcinoma.

For patients with localized pancreatic cancer with minimal vascular involvement, optimal survivability requires a multidisciplinary approach of surgical resection and systemic chemotherapy. FOLFIRINOX is a combination chemotherapy regimen that offers promising results in the perioperative and metastatic settings; however, it can cause significant adverse effects. Such toxicity can negatively impact some patients, resulting in chemotherapy discontinuation or surgical unsuitability. In an effort to reduce toxicities and optimize outcomes, this investigation explores the safety and feasibility of substituting liposomal irinotecan (nal-IRI) for nonliposomal irinotecan to improve tumor drug delivery and potentially reduce toxicity. This regimen, NALIRIFOX, has the potential to be both safer and more effective when administered in the preoperative setting.

For patients with pancreatic cancer with little to no cancer near the blood vessels, the best life expectancy usually requires surgery and chemotherapy. FOLFIRINOX is a chemotherapy medicine that offers promising results for both patients getting surgery and for patients with widespread disease. However, it can cause harmful side effects. The side effects can be so bad that the chemotherapy has to be stopped or that surgery is no longer possible. In order to reduce the harmful side effects and improve outcomes, this investigation looks into the safety and practicality of using a different version of one of the medicines. The different version hopes to improve drug delivery and reduce harmful side effects. This regimen, NALIRIFOX, can be safer and more effective in patients awaiting surgery.

Hypercalcemia Resulting from Necrotizing Leiomyoma in a Pregnant Female.

BACKGROUND Hypercalcemic crisis is defined as a serum calcium level >14 mg/dL in a symptomatic patient. While severe hypercalcemia during pregnancy is rare, it poses a life-threatening risk to both mother and fetus. Hypercalcemia in association with a benign tumor such as a leiomyoma is exceedingly rare. CASE REPORT A 38-year-old primagravida at 31.2 week's gestation conceived by in vitro fertilization presented to the emergency department for complaints of nausea, vomiting, and epigastric abdominal pain. Her fetal monitor strip was reassuring. A complete metabolic panel on admission was significant for severely elevated calcium of 15.9 mg/dL (8.6-10.3 mg/dL) and an elevated lipase of 1457U/L (11-82 U/L). She was started on aggressive intravenous fluid resuscitation, but became confused and lethargic, unarousable to verbal stimuli, as a result of hypercalcemia. Computed tomography (CT) scan of the abdomen and pelvis revealed a heterogeneously enhancing, placental-appearing soft tissue mass extending posteriorly and to the right that measured 2414 cm. The patient subsequently underwent planned low transverse cesarean delivery and exploratory laparotomy for myomectomy with removal of a 2834-g benign leiomyoma measuring 19.018.514.0 cm. Her serum parathyroid hormone-related protein (PTHrP) was elevated to 9.6 pmol/L (<4.2 pmol/L). The patient's calcium normalized to 9.8 mg/dL (8.6-10.3mg/dL) immediately following surgery. CONCLUSIONS Leiomyoma as a cause of hypercalcemia should be included in the differential diagnosis because surgical removal of leiomyoma is curative. Particularly in pregnant patients, for whom medical therapies for hypercalcemia are limited and those available can result in complications, early identification and surgical resection can be life saving.

Germline BAP1 mutation in a family with high incidence of multiple primary cancers and a potential gene-environment interaction.

We report a high-risk cancer family with multiple mesotheliomas, cutaneous melanomas, basal cell carcinomas, and meningiomas segregating with a germline nonsense mutation in BAP1 (c.1938T>A; p.Y646X). Notably, most (four of five) mesotheliomas were peritoneal rather than the usually more common pleural form of the disease, and all five mesothelioma patients also developed second or third primary cancers, including two with meningiomas. Another family member developed both cutaneous melanoma and breast cancer. Two family members had basal cell carcinomas, and six others had melanocytic tumors, including four cutaneous melanomas, one uveal melanoma, and one benign melanocytic tumor. The family resides in a subtropical area, and several members had suspected exposure to asbestos either occupationally or in the home. We hypothesize that the concurrence of a genetic predisposing factor and environmental exposure to asbestos and UV irradiation contributed to the high incidence of multiple cancers seen in this family, specifically mesothelioma and various uveal/skin tumors, respectively.

Safety and activity of alisertib, an investigational aurora kinase A inhibitor, in patients with breast cancer, small-cell lung cancer, non-small-cell lung cancer, head and neck squamous-cell carcinoma, and gastro-oesophageal adenocarcinoma: a five-arm phase 2 study.

BACKGROUND: Alisertib is an investigational, oral, selective inhibitor of aurora kinase A. We aimed to investigate the safety and activity of single-agent alisertib in patients with predefined types of advanced solid tumours. METHODS: We did a multicentre phase 1/2 study at 40 centres in four countries (Czech Republic, France, Poland, and the USA). Here, we report results from phase 2; enrolment for the study began on Feb 16, 2010, and ended on May 3, 2013. Adult patients were eligible for the study if they had either breast cancer, small-cell lung cancer, non-small-cell lung cancer, head and neck squamous-cell carcinoma, or gastro-oesophageal adenocarcinoma that had relapsed or was refractory to chemotherapy. Patients had to have undergone two or fewer previous cytotoxic regimens (four or fewer for breast cancer patients), not including adjuvant or neoadjuvant treatments. Enrolment followed a two-stage design: to proceed to the second stage, two or more objective responses were needed in the first 20 response-assessable patients in each of the five tumour cohorts. Alisertib was administered orally in 21-day cycles at the recommended phase 2 dose of 50 mg twice daily for 7 days followed by a break of 14 days. The protocol-specified primary endpoint was the proportion of patients with an objective response, assessed by Response Evaluation Criteria In Solid Tumors version 1.1 in the response-assessable population (ie, patients with measurable disease who received at least one dose of alisertib and had undergone at least one post-baseline tumour assessment). This completed trial is registered with ClinicalTrials.gov, NCT01045421. FINDINGS: By May 31, 2013, 249 patients had been treated, 53 with breast cancer, 60 with small-cell lung cancer, 26 with non-small-cell lung cancer, 55 with head and neck squamous-cell carcinoma, and 55 with gastro-oesophageal adenocarcinoma. Among response-assessable patients, an objective response was noted in nine (18%, 95% CI 9-32) of 49 women with breast cancer, ten (21%, 10-35) of 48 participants with small-cell lung cancer, one (4%, 0-22) of 23 patients with non-small-cell lung cancer, four (9%, 2-21) of 45 people with head and neck squamous-cell carcinoma, and four (9%, 2-20) of 47 individuals with gastro-oesophageal adenocarcinoma; all were partial responses. Adverse events were similar across tumour types. The most frequent drug-related grade 3-4 adverse events included neutropenia (n=107 [43%]), leukopenia (53 [21%]), and anaemia (26 [10%]). Serious drug-related adverse events were reported in 108 (43%) patients. INTERPRETATION: These data support further clinical assessment of alisertib in patients with solid tumours, particularly those with breast cancer and small-cell lung cancer.

Successful gestation and delivery using clopidogrel for secondary stroke prophylaxis: a case report and literature review.

Literature is scarce regarding the use of clopidogrel during pregnancy and the potential hazard to maternal and fetal health. We report a 33-year-old female, who presented to our clinic at 40 weeks gestation with a history of multiple prior ischemic strokes and transient ischemic attacks. The patient was placed on clopidogrel for secondary stroke prophylaxis prior to conception and maintained therapy throughout pregnancy without interruption or complication. Clopidogrel was discontinued 7 days prior to induction of labor, and a healthy baby was vaginally delivered without bleeding complications or congenital anomalies. Clopidogrel was restarted 12 hours postpartum without an incident. To our knowledge, this is the first report of clopidogrel use in pregnancy for secondary stroke prophylaxis. We also provide a current review of the literature of the use of clopidogrel in pregnancy. Based on the limited data available, clopidogrel use in pregnancy has not demonstrated significant toxicity to either the mother or the newborn. However, additional studies are needed to further assess the efficacy and safety of this medication in this patient population.

Expression of specificity protein transcription factors in pancreatic cancer and their association in prognosis and therapy.

Pancreatic cancer is an aggressive malignancy with poor prognosis. Pancreatic adenocarcinoma is one of the leading causes of cancer-related deaths in the United States. Due to the aggressive nature of this malignancy, there is a serious concern for identifying effective targets, and adopting novel strategies for therapy. Members of the Specificity Protein (Sp) family of transcription factors, Sp1, Sp3, and Sp4 regulate the expression of a number of genes associated with cancer cell proliferation, differentiation, and metastasis. Sp1 levels are upregulated in pancreatic cancer cell lines, and surgically resected human pancreatic adenocarcinoma. Sp1 overexpression in tumor tissues is associated with aggressive disease, poor prognosis and inversely correlated with survival. Sp1 is also known to affect angiogenesis by regulating the expression of vascular endothelial growth factor and its receptors. Results from clinical studies suggest Sp1 as new biomarker to identify aggressive pancreatic ductal adenocarcinoma. The pharmacological inhibition of Sp1 using agents such as celecoxib, mithramycin, curcumin, and tolfenamic acid has showed promising results in pre-clinical studies and demonstrated Sp transcription factors as potential targets for pancreatic cancer therapy. This review summarizes studies showing the association of Sp proteins with this malignancy, with a special emphasis on pre-clinical studies that tested strategies to target Sp transcription factors for inhibiting human pancreatic cancer cell proliferation and tumor growth in laboratory animals. The results showed remarkable efficacy and suggest that such approaches have the potential for high success in developing clinically relevant strategies for treating pancreatic cancer.

A phase II randomized study of cetuximab and bevacizumab alone or in combination with gemcitabine as first-line therapy for metastatic pancreatic adenocarcinoma.

The purpose of this study was to assess the efficacy and safety of bevacizumab plus cetuximab with or without gemcitabine in patients with advanced pancreatic adenocarcinoma. Patients with locally advanced or metastatic pancreatic adenocarcinoma, previously untreated, were randomized to bevacizumab (10 mg/kg q2w) plus cetuximab (400/250 mg/m(2) initial/weekly), either with (Arm A) or without (Arm B) gemcitabine (1000 mg/m(2) weekly × 3 of 4 weeks). Tumor assessments were performed q8w. Primary study endpoint was progression-free survival (PFS). Sixty-one patients were randomized to Arm A (n = 30) or Arm B (n = 31). Median treatment duration was 9 weeks in Arm A and 8 weeks in Arm B (range, 2.0-40.4). Patients in Arm A had median PFS and overall survival values of 3.55 months and 5.41 months, respectively, compared to 1.91 months and 4.17 months in Arm B. The study closed early due to lack of sufficient efficacy in both treatment arms. Although both regimens were well tolerated, patients treated with gemcitabine experienced more grade 3-4 toxicities, including proteinuria and thromboembolic events. The combination of cetuximab and bevacizumab did not result in promising activity with or without gemcitabine, suggesting that a strategy of dual EGFR/VEGF inhibition in pancreatic cancer does not warrant further development. To our knowledge, this is one of the first trials to evaluate a completely noncytotoxic regimen in the first-line treatment of advanced pancreatic cancer. (ClinicalTrials.gov number, NCT00326911).
