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].
