New research strategies in retroperitoneal sarcoma. The case of TARPSWG, STRASS and RESAR: making progress through collaboration

Purpose of review Retroperitoneal sarcoma (RPS) is a rare disease, and until recently, its natural history and outcome were poorly understood. Recently, collaborations between individual centers have led to an unprecedented collection of retrospective and prospective data and successful recruitment to the first randomized trial as described here. Recent findings A debate about the beneficial role of extended surgery in RPS triggered an initial collaboration between Europe and North America, the TransAtlantic RetroPeritoneal Sarcoma Working Group (TARPSWG). This collaboration has been instrumental in harmonizing the surgical approach among expert centers, characterizing the pattern of postresection failure of the different histological subtypes, identifying new ways to stage RPS and testing the role of preoperative radiotherapy in a randomized fashion (STRASS-1 study). The collaboration has now expanded to include centers from Asia, Australia and South America. A prospective registry has been started and a new randomized trial, STRASS-2, is in preparation to analyze the role of neoadjuvant chemotherapy for high-grade liposarcoma and leiomyosarcoma of the retroperitoneum. Summary Collaboration is critical to study a rare disease like RPS. Both retrospective and prospective data are useful to improve knowledge, generate hypotheses and build evidence to test, whenever possible, in clinical trials.

Introduction: Chronic lymphocytic leukemia (CLL) is the most frequent form of leukemia in adult population and chemotherapy resistance occurs in 15 –30% of patients with elevated genomic complexity. Apoptosis resistance and induction of a protective form of autophagy are possible explanations of the poor responsivity of CLL to conventional and novel therapeutic drugs. Given the difficulties to maintain in culture B-CLL lymphocytes, the HG3 ce ll line represents an interesting preclinical model to study the effects of natural bioactive molecules or extracts derived from food matrix as potential, chemo-sensitizers in CLL.

Knee pain due to arthritis or injury is the second most common cause of chronic pain in the United States. Osteoarthritis affects more than 30 million adults in the United States. And the rate of anterior cruciate ligament (ACL) tears among children and teens has been increasing about 2.3% per year for the past two decades, according to a new study. The specific cause of a patient’s knee pain has always been difficult to determine because diagnostic tools such as x-ray or MRI only image the joint in a static standing or lying down position, not in motion when the patient is feeling pain. â€...

In this study, we describe the results of surveillance for psittacid herpesviruses (PsHVs), psittacine adenovirus (PsAdV), BFDV and C. psittaci in wild cacatuids in Victoria, Australia. Samples were collected from 55 birds of four species, and tested using genus or family-wide polymerase chain reaction methods coupled with sequencing and phylogenetic analyses for detection and identification of known and novel pathogens. There were no clinically observed signs of illness in most of the live birds in this study (96.3%; n = 53). Beak and Feather Disease Virus was detected with a prevalence of 69.6% (95% CI 55.2...

Authors: Grossmann M, Ramchand SK, Milat F, Vincent A, Lim E, Kotowicz MA, Hicks J, Teede HJ Abstract INTRODUCTION: Representatives appointed by relevant Australian medical societies used a systematic approach for adaptation of guidelines (ADAPTE) to formulate clinical consensus recommendations on assessment and management of bone health in women with oestrogen receptor-positive early breast cancer receiving endocrine therapy. The current evidence suggests that women receiving adjuvant aromatase inhibitors and pre-menopausal woman treated with tamoxifen have accelerated bone loss and that women receiving adjuvant a...
