BACKGROUND: Extensive lytic lesions of the vertebral body (VB) increase risk of fracture and instability and require stabilization of the anterior column. Vertebral augmentation is an accepted treatment option, but when osteolysis has extensively destroyed the VB cortical boundaries (a condition herein defined as 'extreme osteolysis'), the risk of cement leakage and/or insufficient filling is high. Vertebral body stents (VBSs) might allow partial restoration of VB height, cement containment, and reinforcement, but their use in extreme osteolysis has not been investigated...

BACKGROUND: Radiation therapy is an indispensable part of various treatment modalities for breast cancer. Specifically, for non-inflammatory locally advanced breast cancer (LABC) patients, preoperative radiotherapy (pRT) is currently indicated as a second line therapy in the event of lack of response to neoadjuvant chemotherapy. Still approximately one third of patients fails to respond favourably to pRT. The aim of this study was to explore molecular mechanisms underlying differential response to radiotherapy (RT) to identify predictive biomarkers and potential targets for increasing radiosensitivity...

Immunotherapy has had increasing use in Medical Oncology for a diverse range of primary malignancies. There are various types of immunotherapy which are grouped based on mechanism of action. In recent decades, the immune checkpoint inhibitors (ICI) immunotherapies have been at the forefront of Medical Oncology, sparked by very encouraging results. Some patients with metastatic cancer who were previously deemed palliative were seeing durable response rates and significant increased survival with ICIs. The mechanism of action of ICIs vary wildly compared to the conventional, cytotoxic chemotherapy, upon which traditional radiology response criteria were based and validated upon...

Colorectal cancer (CRC) is the third most common cancer worldwide, with a global incidence of over 1 million cases. In the era of personalized medicine, tumor sampling is essential for characterizing the molecular profile of individual tumors. This provides pivotal information regarding optimal sequencing of therapy and emergence of drug resistance, allowing for timely therapy adjustment. However, tumor tissue sampling offers static information in a single time point and area of disease at the time of biopsy, which may not entirely represent the heterogeneity of molecular alterations...

Neuroendocrine tumors (NEN) are rarely diagnosed neoplasms, which frequency is estimated on about 35 cases/100 000. During last 30 years the number of NEN's new diagnosis increased five-times and nowadays reaches 5,86/100 000/year. It is partially associated with increasing detectability of these tumors. Such diagnostic methods as capsule endoscopy and positron emission tomography are becoming increasingly widely accessible. Though, one should bear in mind that in case of patients diagnosed with NEN cooperation between specialists in different fields of medicine, such as endocrinology, nuclear medicine, oncology, radiology, internal medicine and surgery is needed...

BACKGROUND: Modulated compliant compressive forces may contribute to durable fixation of implant stems in patients with cancer who undergo endoprosthetic reconstruction after tumor resection. Chemotherapy effects on bone hypertrophy and osteointegration have rarely been studied, and no accepted radiologic method exists to evaluate compression-associated hypertrophy. QUESTIONS/PURPOSES: (1) What was the effect of chemotherapy on the newly formed bone geometry (area) at 1 year and the presumed osteointegration? (2) What clinical factors were associated with the degree of hypertrophy? (3) Did the amount of bone formation correlate with implant fixation durability? (4) Was the amount of new bone generation or chemotherapy administration correlated with Musculoskeletal Tumor Society (MSTS) score? METHODS: Between 1999 and 2013, we performed 245 distal femoral reconstructions for primary or revision oncologic indications...

A 39-year-old female patient was referred to our tertiary oncologic center for additional investigations relating to a suspect pancreatic tail lesion. An abdominal computed tomography scan and magnetic resonance imaging scan showed a solid lesion demonstrating progressive enhancement. Complete resection was obtained and the final diagnosis was that of a desmoid tumor of the pancreas, an exceptionally rare tumor demonstrating overlap with other solid and cystic lesions of the pancreas [1]. Therefore, it is important to recognize the essential role of pathology, particularly immunohistochemistry, in identifying this tumor...

Assessing tumor response is a large part of everyday clinical work in neuroradiology. However in the setting of tumor treatment, distinguishing tumor progression from treatment-related changes is difficult on conventional MRI sequences. This is made even more challenging in children where mainstay advanced imaging techniques that are often used to decipher progression versus treatment-related changes have technical limitations. In this review, we highlight the challenges in pediatric neuro-oncologic tumor assessment with discussion of pseudophenomenon including pseudoresponse and pseudoprogression...
