Benign peripheral nerve sheath tumors (BPNSTs) are a vast, common, heterogeneous group of lesions that are often diagnostically challenging. The head and neck region is recognized as the second most common location for these lesions, especially the tongue. However, BPNSTs occurring centrally within the jaw bones are exceedingly rare.

Article Synopsis
  • Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer that tends to spread, and this study looks at the survival outcomes of Stage IV MCC patients based on where their metastases are located at diagnosis.
  • The research involved 34 patients diagnosed with distant metastatic MCC between 2009 and 2023, analyzing their overall survival (OS), progression-free survival (PFS), and response rates regarding metastasis sites, using statistical methods to determine significance.
  • Key findings showed that bone metastases were linked to significantly shorter OS, while lymph node metastases correlated with lower MCC-specific death; however, the number and location of metastases did not affect overall treatment response.

Nutraceutical Capsules LL1 and Silymarin Supplementation Act on Mood and Sleep Quality Perception by Microbiota-Gut-Brain Axis: A Pilot Clinical Study.

Nutrients

September 2024

Laboratório de Produtos e Derivados Naturais, Laboratório de Investigação Médica-26 (LIM-26), Departamento de Cirurgia, Faculdade de Medicina de São Paulo, Universidade de São Paulo, São Paulo 01246-903, SP, Brazil.

Stress, unhealthy lifestyle, and sleep disturbance worsen cognitive function in mood disorders, prompting a rise in the development of integrative health approaches. The recent investigations in the gut-brain axis field highlight the strong interplay among microbiota, inflammation, and mental health. Thus, this study aimed to investigate a new nutraceutical formulation comprising prebiotics, minerals, and silymarin's impact on microbiota, inflammation, mood, and sleep quality.

Polyploid Giant Cancer Cells (PGCCs) have been recognized as tumor cells that are resistant to anticancer therapies. However, it remains unclear whether their presence in the bloodstream can be consistently detected and utilized as a clinical marker to guide therapeutic anticancer regimens. To address these questions, we conducted a retrospective study involving 228 patients diagnosed with six different types of carcinomas (colon, gastric, NSCLC, breast, anal canal, kidney), with the majority of them (70%) being non-metastatic.

Background: Gastric cancer is the fifth most common neoplasm and the third leading cause of cancer-related death worldwide. Neoadjuvant chemotherapy is recommended for Stages II-III resectable tumors, but the comparative effectiveness of minimally invasive surgery (MIS) versus open gastrectomy (OG) post-neoadjuvant therapy has not been adequately investigated.

Methods: A retrospective cohort analysis was performed on patients with clinical Stage II and III gastric adenocarcinoma who underwent neoadjuvant chemotherapy followed by either MIS or OG between 2007 and 2020.

Salivary gland scintigraphy (SGS) is an imaging technique to evaluate functional aspects of the salivary glands. First described in 1965, visual analyses of summed images and of time-activity curves generated through regions of interest (ROI) are still the main evaluation tools used in clinical practice. An alternative to ROI-based analysis is the use of parametric images, which are images generated through pixel-by-pixel calculation of parameters from the original frames.

Low-grade fibromyxoid sarcoma and sclerosing epithelioid fibrosarcoma, outcome of advanced disease: retrospective study from the Ultra-Rare Sarcoma Working Group.

ESMO Open

September 2024

Department of Medical Oncology, Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy. Electronic address:

Article Synopsis
  • A retrospective study by the Ultra-Rare Sarcoma Working Group analyzed data from 101 patients with metastatic low-grade fibromyxoid sarcoma (LGFMS), sclerosing epithelioid fibrosarcoma (SEF), and hybrid (H)-LGFMS/SEF across 28 centers from January 2000 to September 2022.
  • The study measured progression-free survival (PFS) from the detection of metastasis and after starting treatment, revealing varying effectiveness among the different sarcoma types and treatments.
  • Findings showed that metastatic LGFMS and SEF had distinct survival outcomes, with systemic treatments showing limited effectiveness, suggesting a need for new therapeutic options in future research.

The German Hodgkin Study Group developed the escalated BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone) protocol as a treatment strategy for advanced-stage Hodgkin's lymphoma. In Brazil, as well as in other countries, procarbazine has been replaced with dacarbazine due to the limited availability of procarbazine. The Hematology Center at Irmandade da Santa Casa de Misericórdia in São Paulo adopted and modified the escalated BEACOPP protocol, substituting prednisone with dexamethasone and incorporating two different doses of dacarbazine: 375 mg/m/day on Day 8 or the original dose of 250 mg/m/day on Days 2 and 3.

Background: Cyclin-dependent kinases (CDK) 4/6 inhibitors have significantly improved outcomes for patients with ER+/HER2- breast cancer. Nevertheless, they differ from each other in terms of chemical, biological, and pharmacological features, as well as toxicity profiles. We aim to determine whether QTc prolongation is caused by CDK4/6i in general or if it is associated with ribociclib only.

Ra-dichloride is an α-emitter therapy approved for the treatment of castration-resistant prostate cancer with symptomatic bone metastases. Ra-dichloride is the first targeted α-therapy for this indication with evidence of benefit in overall survival. The administration is intravenous, and extravasation can cause severe injuries such as tissue necrosis.

Article Synopsis
  • The case involves a 76-year-old male who received multiple endodontic treatments for a misdiagnosed glandular odontogenic cyst, which was initially mistaken for an inflammatory periapical lesion.
  • Glandular odontogenic cysts are known to be more aggressive compared to other types, and there's a lack of extensive research on this in older dental patients.
  • The correct diagnosis was confirmed through a biopsy, leading to successful surgery while ensuring the base of the mandible was preserved, emphasizing the need for careful diagnosis in elderly patients.

Metabolic imaging in clinical practice has long relied on PET with fluorodeoxyglucose (FDG), a radioactive tracer. However, this conventional method presents inherent limitations such as exposure to ionizing radiation and potential diagnostic uncertainties, particularly in organs with heightened glucose uptake like the brain. This review underscores the transformative potential of traditional deuterium MR spectroscopy (MRS) when integrated with gradient techniques, culminating in an advanced metabolic imaging modality known as deuterium MRI (DMRI).

  • The study looked at how different types of breast cancer appear on MRI scans, focusing on a specific kind called ER-low-positive breast cancer.
  • Out of 398 patients, they found that various types of breast cancer showed different MRI features, like shape and edges of the tumors.
  • Both ER-low-positive and triple-negative tumors had similar MRI findings, which could help doctors plan the best treatment for patients.

Background: Human epidermal growth factor receptor 2 (HER2)-low breast cancer has emerged as a new subtype of tumor, for which novel antibody-drug conjugates have shown beneficial effects. Assessment of HER2 requires several immunohistochemistry tests with an additional in situ hybridization test if a case is classified as HER2 2+. Therefore, novel cost-effective methods to speed up the HER2 assessment are highly desirable.

Article Synopsis
  • A systematic review and meta-analysis evaluated the recurrence and progression risk of oral potentially malignant disorders (OPMD) and precancerous lesions after surgical treatments across various body sites.
  • Twelve studies were included, revealing that the variation in surgical protocols and unclear margin descriptions affected clinical outcomes, particularly for oral leukoplakia and anal intraepithelial neoplasia.
  • The analysis found no significant difference in recurrence risk between cold-knife and ablative treatments for oral leukoplakia and cervical intraepithelial neoplasia, highlighting the need for standardized surgical approaches.
