The expression of vimentin, as assessed by immunohistochemistry, has been evaluated in 69 medullary carcinomas of the breast: 28 typical medullary carcinomas (TMC), 41 atypical medullary carcinomas (AMC), and 29 invasive ductal carcinomas with subtle medullary features that, however, did not fulfill the strict criteria of TMC or AMC. Immunoreactivity of at least 10% of the component cells was found in 14 of the medullary carcinomas (5 out of 28 TMC, 9 out of 41 AMC whereas only 1 of the invasive ductal carcinomas was vimentin-positive. The patients were followed for 8-13 years. No difference in recurrence-free survival or overall survival could be documented between vimentin-positive and vimentin-negative carcinomas with medullary features. No biological significance could be established for vimentin labelling in these lesions.

The Efficacy and Safety of Anlotinib in the Treatment of Thyroid Cancer: A Systematic Review.
J Clin Med
January 2025
Abdominal Surgery and Phlebology Research Center, "Victor Babes" University of Medicine and Pharmacy Timisoara, 300041 Timisoara, Romania.
Anlotinib, a novel multi-kinase inhibitor targeting angiogenesis and tumor proliferation pathways, has shown promising efficacy in various cancers. Its role in treating thyroid cancer, particularly radioactive iodine-refractory differentiated thyroid cancer (RAIR-DTC), medullary thyroid carcinoma (MTC), and anaplastic thyroid carcinoma (ATC), is of significant clinical interest. This systematic review aims to evaluate the efficacy and safety of Anlotinib in patients with thyroid cancer, analyzing outcomes such as progression-free survival (PFS), overall survival (OS), response rates, and adverse events.

: Medullary carcinoma of the small intestine is an exceptionally rare subtype of gastrointestinal cancer, characterized by its solid growth pattern and lack of glandular structures, which complicate timely diagnosis. During the COVID-19 pandemic, diagnostic delays for rare cancers became increasingly common due to the prioritization of COVID-related cases and patient reluctance to seek medical attention. : We present the case of a 70-year-old male initially misdiagnosed with COVID-19, whose persistent symptoms led to the eventual discovery of medullary carcinoma.

In the context of modern cancer therapy, the management of adverse effects of systemic therapies can lead to the avoidance of underdosing and withdrawal and increases in the quality of the therapeutic act and the quality of life. This review offers an overview of the skin-related toxicities associated with Cabozantinib, a multikinase inhibitor (MKI) that is approved for treating advanced kidney cancer, hepatocellular carcinoma, and medullary thyroid cancer. It covers the most common dermatological side effects, such as palmar-plantar erythrodysesthesia, stomatitis, hair alterations, xerosis, scrotal erythema, and subungual splinter hemorrhages.

Renal cell carcinoma (RCC) is a heterogeneous disease that represents the most common type of kidney cancer. The classification of RCC is primarily based on distinct morphological and molecular characteristics, with two broad categories: clear cell RCC (ccRCC) and non-clear cell RCC (nccRCC). Clear cell RCC is the predominant subtype, representing about 70-80% of all RCC cases, while non-clear cell subtypes collectively make up the remaining 20-30%.

In non-papillary follicular cell-derived thyroid carcinomas, prognostic factors are scarce. Intratumoral fibrosis was identified as an adverse factor in papillary and medullary carcinomas, but it has not been investigated in other subtypes. We aimed at exploring the presence of intratumoral fibrosclerosis in a cohort of 132 non-papillary follicular cell-derived thyroid carcinomas (53 follicular and 31 oncocytic carcinomas, including 10 high grade differentiated thyroid carcinomas and 48 poorly differentiated carcinomas) and correlating its presence and extent with clinical and pathological features and survival.
