We have hypothesized that biofabrication of appendiceal tumor organoids allows for a more personalized clinical approach and facilitates research in a rare disease. ⋯ Development of 3D appendiceal tumor organoids is feasible even in low cellularity LGA tumors, allowing for individual patient tumors to remain viable for research and personalized drug screening.

Anti-vascular endothelial growth factor (VEGF) therapy has demonstrated efficacy in treating human metastatic cancers, but therapeutic resistance is a practical limitation and most tumors eventually become unresponsive. To identify microenvironmental factors underlying the resistance of cancer to antiangiogenesis therapy, we conducted genomic analyses of intraperitoneal ovarian tumors in which adaptive resistance to anti-VEGF therapy (B20 antibody) developed. We found that expression of the microseminoprotein, prostate-associated (MSMP) gene was substantially upregulated in resistant compared with control tumors. ⋯ MSMP siRNA, delivered in vivo using the DOPC nanoliposomes, restored tumor sensitivity to anti-VEGF therapy. In ovarian cancer patients treated with bevacizumab, serum MSMP concentration increased significantly only in non-responders. These findings imply that MSMP inhibition combined with the use of antiangiogenesis drugs may be a new strategy to overcome resistance to antiangiogenesis therapy.

Review Case ReportsProviding Appropriate End-of-Life Care to Religious and Ethnic Minorities.
There is overwhelming evidence that racial and ethnic minorities face multiple health care disparities. Recognizing and addressing cultural and religious/spiritual (RS) values is a critical aspect of providing goal-concordant care for patients facing a serious illness, especially at the end of life. Failure to address a patient's cultural and RS needs can lead to diminished quality of care and worse health outcomes. Given the multitude of cultural and RS values, we believe that a framework of cultural and RS curiosity along with a willingness to engage patients in discussions about these elements of their care within an interdisciplinary team should be the goal of all providers who are discussing goals, preferences, and values with patients facing advanced terminal illness.

Thrombocytosis has been associated with poor ovarian cancer prognosis. However, comparisons of thresholds to define thrombocytosis and evaluation of relevant timing of platelet measurement has not been previously conducted. ⋯ Our EMR approach yielded associations comparable to published findings from medical record abstraction approaches. In addition, our results indicate that lower thrombocytosis thresholds and platelet measures up to 8 weeks before diagnosis may inform ovarian cancer characteristics and prognosis.

Randomized Controlled Trial Multicenter StudyStandard first-line chemotherapy with or without nintedanib for advanced ovarian cancer (AGO-OVAR 12): a randomised, double-blind, placebo-controlled phase 3 trial.
Angiogenesis is a target in the treatment of ovarian cancer. Nintedanib, an oral triple angiokinase inhibitor of VEGF receptor, platelet-derived growth factor receptor, and fibroblast growth factor receptor, has shown activity in phase 2 trials in this setting. We investigated the combination of nintedanib with standard carboplatin and paclitaxel chemotherapy in patients with newly diagnosed advanced ovarian cancer. ⋯ Boehringer Ingelheim.
