Purpose: Epithelioid hemangioendothelioma (EHE) is a rare vascular cancer with pathogenic TAZ-CAMTA1 (calmodulinbinding transcription activator 1) operating as an oncogenic driver through activation of the MAPK pathway. Trametinib is an inhibitor of MEK, a critical kinase in the MAPK pathway. We sought to evaluate the effect of trametinib in patients with EHE.

Background: Alveolar soft part sarcoma (ASPS) is a rare soft-tissue sarcoma with a poor prognosis and no established therapy. Recently, encouraging responses to immune checkpoint inhibitors have been reported.

Methods: We conducted an investigator-initiated, multicenter, single-group, phase 2 study of the anti-programmed death ligand 1 (PD-L1) agent atezolizumab in adult and pediatric patients with advanced ASPS.

Background: EBRT in resected, nonmetastatic anaplastic thyroid cancer (ATC) remains undefined. We evaluated patterns/outcomes with EBRT and chemotherapy in this setting.

Methods: This retrospective analysis included patients identified from the National Cancer Database with nonmetastatic ATC from 2004 to 2014 who underwent non-palliative resection.

Background: Desmoid tumors (also referred to as aggressive fibromatosis) are connective tissue neoplasms that can arise in any anatomical location and infiltrate the mesentery, neurovascular structures, and visceral organs. There is no standard of care.

Methods: In this double-blind, phase 3 trial, we randomly assigned 87 patients with progressive, symptomatic, or recurrent desmoid tumors to receive either sorafenib (400-mg tablet once daily) or matching placebo.

DNA methylation in human papillomavirus-associated (HPV) head and neck squamous cell carcinoma (HNSCC) may have importance for continuous expression of HPV oncogenes, tumor cell proliferation, and survival. Here, we determined activity of a global DNA-demethylating agent, 5-azacytidine (5-aza), against HPV HNSCC in preclinical models and explored it as a targeted therapy in a window trial enrolling patients with HPV HNSCC. Sensitivity of HNSCC cells to 5-aza treatment was determined, and then 5-aza activity was tested using xenografted tumors in a mouse model.

Importance: Men with metastatic prostate cancer who have a poor response to initial androgen-deprivation therapy (ADT), as reflected by a prostate-specific antigen (PSA) level higher than 4.0 ng/mL after 7 months of ADT, have a poor prognosis, based on historical controls.

Objective: To determine the efficacy of abiraterone acetate with prednisone in these high-risk patients with a suboptimal response to hormonal induction.

This case confirms the observation that urothelial carcinomas can secrete beta-hCG, and that beta-hCG can potentially be used as a marker of a patient's clinical response to treatment. Prospective studies are clearly warranted by these observations.

Purpose Of Review: Anaplastic thyroid cancer is the most aggressive solid tumor known to humans. Even when found in a localized form, the prognosis is grave. For metastatic disease, there has been little effect on survival using traditional chemotherapy.

Medullary thyroid cancer (MTC) represents an aggressive form of thyroid malignancy. Some may occur spontaneously or can be associated with Multiple Endocrine Neoplasia syndromes, or Familial Medullary Thyroid Cancer syndrome. In these patients, the protooncogene RET (rearranged during transfection) is mutated.

Introduction: Thyroid cancer is a rare disease with an incidence of around 37,000 cases per year. However, its incidence is rising faster than many other cancers and for men this disease ranks highest overall in the rate of increase (2.4% annual increase) in cancer deaths.

The treatment of thyroid cancer is evolving. The molecular mechanisms of carcinogenesis for many thyroid cancers have been investigated, and have yielded targets for potential therapies. These targets include VEGFR in the treatment of all thyroid cancers, BRAF in the treatment of papillary thyroid cancer, and RET in the treatment of medullary thyroid cancer (MTC).

Purpose Of Review: Endocrine tumors are often overlooked in medical oncology discussions, as many of them are effectively cured by surgery alone or surgery plus an ablative radiation therapy. For the rare aggressive endocrine cancers that are widely metastatic or rapidly progressive, however, the role of the medical oncologist becomes more important. To date, conventional chemotherapy has not had a significant impact on the natural history of these malignancies.
