Case report: Treatment with Phesgo® in a patient receiving hemodialysis.

Introduction: Patients with metastatic HER2-positive breast cancer have multiple therapeutic options. However, most are not studied in the renal replacement therapy (RRT) setting.

Case Report: We report the use of Phesgo® (subcutaneous fixed-dose combination of trastuzumab and pertuzumab) combined with exemestane as a first-line treatment of metastatic HER2-positive breast cancer in a hemodialysis patient with multiple comorbidities.

Loss of RAS Mutations in Liquid Biopsies of Patients With Multi-Treated Metastatic Colorectal Cancer.

Background: Liquid biopsy (LB) is a non-invasive tool to evaluate the heterogeneity of tumors. Since RAS mutations (RAS-mut) play a major role in resistance to antiepidermal growth factor receptor inhibitors (EGFR) monoclonal antibodies (Mabs), serial monitoring of RAS-mut with LB may be useful to guide treatment. The main aim of this study was to evaluate the prognostic value of the loss of RAS-mut (NeoRAS-wt) in LB, during the treatment of metastatic colorectal cancer (mCRC).

A Rare Case of Isolated Prostate Recurrence From Testicular Seminoma.

We report the case of a 32-year-old male diagnosed with a left-sided testicular seminoma treated with radical inguinal orchiectomy and staged as pT1bN0M0S0 ( invasion) - stage IA. Adjuvant treatment options were discussed, and active surveillance was chosen. Two years later, he presented with urinary retention alternating with pollakiuria, a feeling of incomplete bladder emptying, dyspareunia, and anejaculation.

Lymph node yield in the pathological staging of resected nonmetastatic colon cancer: The more the better?

Introduction: Guidelines recommend regional lymphadenectomy with a lymph node yield (LNY) of at least 12 lymph nodes (LN) for adequate colon cancer (CC) staging. LNY ≥22LN may improve survival, especially in right-sided CC [Lee et al., Surg Oncol, 27(3), 2018].

SARS-CoV-2 Antibody Seroprevalence in Patients With Cancer on Systemic Antineoplastic Treatment in the First Wave of the COVID-19 Pandemic in Portugal.

At the time of the first wave of the COVID-19 pandemic, patients with cancer were considered to be at high risk of serious illness and had a higher exposure risk since they needed frequent and nondeferrable hospital visits. Serological tests were not routinely used, and seroprevalence in this population was unknown. A single-center, cross-sectional study was developed to determine the seroprevalence of anti-SARS-CoV-2 antibodies (Abs) in patients with cancer undergoing systemic antineoplastic treatment.

The Eastern side of the Westernmost Europeans: Insights from subclades within Y-chromosome haplogroup J-M304.

Objectives: We examined internal lineages and haplotype diversity in Portuguese samples belonging to J-M304 to improve the spatial and temporal understanding of the introduction of this haplogroup in Iberia, using the available knowledge about the phylogeography of its main branches, J1-M267 and J2-M172.

Methods: A total of 110 males of Portuguese descent were analyzed for 17 Y-chromosome bi-allelic markers and seven Y-chromosome short tandem repeats (Y-STR) loci.

Results: Among J1-M267 individuals (n = 36), five different sub-haplogroups were identified, with the most common being J1a2b2-L147.

[Splenic Epidermoid Cyst--imaging features].

Splenic Epidermoid Cyst is a rare entity and the imaging methods play a major role in the diagnosis, although this can only be accomplished by the histological features. The authors report a case of splenic epidermoid cyst in a child of eleven years old, which presented with one month history of post-traumatic abdominal pain. They illustrate the imaging features on ultrasound, CT and MR with pathologic correlation.
