Pretreatment hemoglobin level as a prognostic factor in patients with locally advanced head and neck squamous cell carcinoma

AimEvaluate pretreatment hemoglobin values as a prognostic factor in patients with locally advanced head and neck squamous cell carcinoma treated with concurrent chemoradiotherapy.BackgroundAnemia is one of the most prevalent laboratory abnormalities in oncological disease. It leads to a decrease in cellular oxygen supply, altering radiosensitivity of tumor cells and compromising therapeutic outcomes.Materials and MethodsRetrospective evaluation of patients with HNSCC treated with cCRT. Primary and secondary endpoint was to evaluate the correlation of Hb levels (≥12.5g/dL o

Genomic Profiling of Sarcomas: A Promising Weapon in the Therapeutic Arsenal

Sarcomas are rare malignant mesenchymal neoplasms, and the knowledge of tumor biology and genomics is scarce. Chemotherapy is the standard of care in advanced disease, with poor outcomes. Identifying actionable genomic alterations may offer effective salvage therapeutic options when previous lines have failed. Here, we report a retrospective cohort study of sarcoma patients followed at our center and submitted to comprehensive genomic profiling between January 2020 and June 2021. Thirty patients were included, most (96.7%) with reportable genomic alterations. The most common alterations were linked to cell cycle regulation (TP53, CDKN2A/B, and RB1 deletions and CDK4, MDM2, and MYC amplifications). Most patients (96.7%) had microsatellite stability and low tumor mutational burden (≤10 muts/megabase (Mb); median 2 Muts/Mb). Two-thirds of patients had actionable mutations for targeted treatments, including five cases with alterations amenable to targeted therapies with clinical benefit within the patient’s tumor type, ten cases with targetable alterations with clinical benefit in other tumor types, and five cases with alterations amenable to targeting with drugs under investigation in a clinical trial setting. A significant proportion of cases in this study had actionable genomic alterations with available targeted drugs. Next-generation sequencing is a feasible option for identifying molecular drivers that can provide therapeutic options for individual patients. Molecular Tumor Boards should be implemented in the clinical practice to discuss genomic findings and inform clinically relevant targeted therapies

Choristoma: a very rare cause of thyroid nodule: case report and literature review

© The Author(s), under exclusive licence to Hellenic Endocrine Society 2024Background: Choristoma is a well-defined benign lesion formed by histologically normal tissue in an unusual location. Diagnosis is confirmed after surgical removal of the mass. To our knowledge, to date there has been only one case of thyroid choristoma described in the literature. Patient findings: A 70-year-old man with a history of non-Hodgkin lymphoma presented with sudden cervical enlargement. Cervical CT scan showed a 47mm hypodense nodule on the right thyroid lobe. Fine-needle aspiration revealed follicular lesion of undetermined significance. During the following weeks there was noticeable thyroid enlargement. Reassessment with thyroid ultrasound showed a 73mm nodule. The patient underwent total thyroidectomy. Histopathological examination revealed a choristoma composed of squamous epithelium lined cysts, smooth muscle, adipose tissue, connective tissue, foci of ossification and extramedullary hematopoiesis. No cytological atypia or tumoral necrosis were found. Thyroid choristomas are an exceedingly rare cause of a thyroid nodule.info:eu-repo/semantics/publishedVersio

Management of Unresectable Localized Pelvic Bone Sarcomas: Current Practice and Future Perspectives

Bone sarcomas (BS) are rare mesenchymal tumors usually located in the extremities and pelvis. While surgical resection is the cornerstone of curative treatment, some locally advanced tumors are deemed unresectable and hence not suitable for curative intent. This is often true for pelvic sarcoma due to anatomic complexity and proximity to vital structures, making treatment options for these tumors generally limited and not unanimous, with decisions being made on an individual basis after multidisciplinary discussion. Several studies have been published in recent years focusing on innovative treatment options for patients with locally advanced sarcoma not amenable to local surgery. The present article reviews the evidence regarding the treatment of patients with locally advanced and unresectable pelvic BS, with the goal of providing an overview of treatment options for the main BS histologic subtypes involving this anatomic area and exploring future therapeutic perspectives. The management of unresectable localized pelvic BS represents a major challenge and is hampered by the lack of comprehensive and standardized guidelines. As such, the optimal treatment needs to be individually tailored, weighing a panoply of patient- and tumor-related factors. Despite the bright prospects raised by novel therapeutic approaches, the role of each treatment option in the therapeutic armamentarium of these patients requires solid clinical evidence before becoming fully established

Usefulness of a clinicopathological classification in predicting treatment-related outcomes and multimodal therapeutic approaches in pituitary adenoma patients: retrospective analysis on a Portuguese cohort of 129 patients from a tertiary pituitary center

© The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2023Purpose: A clinicopathological classification has been designed to predict recurrence/progression in patients with pituitary adenomas (PAs). We aimed to study its usefulness in predicting PAs that will have a challenging disease course and may require more often complex multimodal and multiple therapeutic approaches. Methods: Retrospective analysis of 129 patients with PAs operated in our institution between 2001 and 2020 (84 non-clinically functioning PAs, 32 acromegaly, 9 Cushing's disease, 2 prolactinomas and 2 thyrotropinomas). Grading was based on invasion and proliferation: 1a (non-invasive, non-proliferative; n = 59), 1b (non-invasive, proliferative; n = 17), 2a (invasive, non-proliferative; n = 38), and 2b (invasive, proliferative; n = 15). Results: Of the 129 patients, 68 (52.7%) were females, and the mean age at diagnosis was 53.7 ± 15.4 years. The mean follow-up duration was 93.1 ± 61.8 months. Grade 2b PAs when compared to other grades (2b-2a-1b-1a) had significantly higher rates of persistent tumor remnant within 1-year after operation (93-78-18-30%; p < 0.001), active disease at last follow-up (40-27-12-10%; p = 0.004), re-operation (27-16-0-5%; p = 0.023), irradiation (53-38-12-7%; p < 0.001), multimodal treatment (67-49-18-25%; p = 0.003), multiple treatment (33-27-6-9%; p = 0.017). Patients with grade 2b PAs also required a higher mean number of treatments (2.6-2.1-1.2-1.4; p < 0.001). Conclusions: This clinicopathological classification appears to be a useful grading system to identify PAs that may be more refractory and more often require complex multimodal and multiple therapeutic approaches. Invasive PAs, especially grade 2b tumors, may be more likely to need complex treatment approach, including radiotherapy, and may display higher rates of active disease at last follow-up, despite receiving higher number of treatments.P.M. was supported by the Neuroendocrine Tumor Research Foundation (NETRF)info:eu-repo/semantics/publishedVersio
