Prospective study on Oncotype DX® assay to assess recurrence risk in early ER-positive HER2-negative breast cancer patients with uncertain biological behavior by standard parameters and its impact on treatment recommendation: The POST trial.

Background: Data published in 2015 showed that patients with early breast cancer (EBC) and a low-risk (LR) Recurrence Score® (RS) result by the 21-gene Oncotype DX® assay ("the test") did not derive benefit from adding chemotherapy (CT) to endocrine therapy (HT), while those with a high-risk (HR) RS result did. However, the role of CT remained uncertain in patients with intermediate-risk (IR) cancers. We designed a study to assess the test's ability to categorize patients with EBC with uncertain biological behavior into the groups (LR and HR) for which the value of additional chemotherapy was defined.

The national COVID-19 vaccination campaign targeting the extremely vulnerable: the Florence Medical Oncology Unit experience in patients with cancer.

Background: International and national oncology societies had released recommendations in favor of COVID-19 vaccination in cancer patients. In the context of the national vaccination campaign targeting the so called extremely vulnerable, we aimed to assess the safety and efficacy of the mRNA vaccines in a cohort of 623 patients.

Methods: Between March 26 and April 04, 2021, the Pfizer and BioNTech BNT162b2 mRNA and the Moderna mRNA-1273 vaccines were given as a two-dose prime-boost regimen.

Gallbladder neuroendocrine neoplasm: a case report and critical evaluation of WHO classification.

Gallbladder neuroendocrine neoplasms (GB-NENs) are rare. The majority of GB-NENs are poorly differentiated, with increased mitotic activity and clinically aggressive course. Surgery is the only curative approach and the optimal medical treatment is uncertain.

Complete pathological response in advanced extra-gastrointestinal stromal tumor after imatinib mesylate therapy: a case report.

Background: Gastrointestinal stromal tumors are uncommon intra-abdominal tumors. In fewer than 5% of cases, they originate primarily from the mesentery, omentum or peritoneum and these extra-gastrointestinal stromal tumors tend to have characteristics similar to gastrointestinal stromal.

Case Report: We report a case of extra-gastrointestinal stromal tumor in a 76-year-old male, Eastern Cooperative Oncology Group (ECOG) performance status of 2.

Tyrosinase mRNA levels in the blood of uveal melanoma patients: correlation with the number of circulating tumor cells and tumor progression.

We measured tyrosinase mRNA levels by real-time quantitative reverse transcription-PCR (qRT-PCR), in the blood of patients with uveal melanoma. Results were correlated with clinical data and, in a subgroup of patients, with the number of circulating tumor cells (CTC) assessed using isolation by size of epithelial tumor cells (ISET). Forty-one patients with uveal melanoma were longitudinally investigated over a period of 5 years.
