Article Synopsis
  • - Patients with advanced/metastatic urothelial carcinoma who previously responded to or maintained stable disease with pembrolizumab immunotherapy may benefit from retreatment after disease progression, based on a post hoc analysis involving 49 patients from earlier clinical trials.
  • - The study found that 41% of these patients achieved an objective response following retreatment, with a notable percentage having had a complete response during the initial treatment, and the median duration of the response was around 14 months.
  • - Additionally, the retreatment led to manageable adverse effects, with only 45% experiencing treatment-related events, indicating that pembrolizumab retreatment is a viable and relatively safe option for select patients.

Testicular germ cell tumors are the most common tumors in adolescent and young men. They are curable malignancies that should be treated with curative intent, minimizing acute and long-term side effects. Inguinal orchiectomy is the main diagnostic procedure, and is also curative for most localized tumors, while patients with unfavorable risk factors for recurrence, or those who are unable or unwilling to undergo close follow-up, may require adjuvant treatment.

Article Synopsis
  • Abemaciclib, a CDK4/6 inhibitor, has shown promise in treating metastatic castration-resistant prostate cancer (mCRPC), potentially shifting treatment approaches similar to its use in breast cancer.
  • In a study involving 44 patients with mCRPC who had previously undergone multiple treatments, the primary goal was to report the objective response rate (ORR), which was found to be 6.8%, with a disease control rate of 45.5%.
  • The treatment was generally well tolerated, with manageable side effects, and provided preliminary evidence supporting CDK4/6 as a therapeutic target in prostate cancer.

Renal cancer is the seventh most common cancer in men and the tenth in women. The aim of this article is to review the diagnosis, treatment, and follow-up of renal carcinoma accompanied by recommendations with new evidence and treatment algorithms. A new pathologic classification of RCC by the World Health Organization (WHO) was published in 2022 and this classification would be considered a "bridge" to a future molecular classification.

The 2021 guidelines on the prevention of vascular disease (VD) in clinical practice published by the European Society of Cardiology (ESC) and supported by 13 other European scientific societies recognize the key role of screening for chronic kidney disease (CKD) in the prevention of VD. Vascular risk in CKD is categorized based on measurements of estimated glomerular filtration rate (eGFR) and urine albumin to creatinine ratio (ACR). Thus, moderate CKD is associated with a high vascular risk and severe CKD with a very high vascular risk requiring therapeutic action, and there is no need to apply other vascular risk scores when vascular risk is already very high due to CKD.

Oligometastatic disease (OMD) defines a cancer status that is intermediate between localized and widely spread metastatic disease, and can be treated with curative intent. While diagnostic imaging tools have considerably improved in recent years, unidentified micrometastases can still evade current detection techniques, allowing the disease to progress. The various OMD scenarios are mainly defined by the number of metastases, the biological and molecular tumour profiles, and the timing of the development of metastases.

Purpose: PI3K-Akt-mTOR and androgen receptor (AR) signaling are commonly aberrantly activated in metastatic castration-resistant prostate cancer (mCRPC), with PTEN loss associating with poor prognosis. We therefore conducted a phase Ib/II study of the combination of ipatasertib, an Akt inhibitor, with the CYP17 inhibitor abiraterone in patients with mCRPC. Patients were randomized 1:1:1 to ipatasertib 400 mg, ipatasertib 200 mg, or placebo, with abiraterone 1,000 mg orally.

Prostate cancer (PC) is the most common cancer in men. Many patients have prolonged survival and die of other diseases, so treatment decisions are often influenced by age and coexisting comorbidities. The main procedure to diagnose PC is an ultrasound-guided core needle biopsy, which is indicated when a digital rectal examination (DRE) finds nodularity or when PSA is >10 ng/ml, but is also recommended with PSA between 4.

Gestational trophoblastic disease consists of a pathological spectrum of entities from molar pregnancies, which are premalignant conditions, to malignant invasive choriocarcinoma. Serum Beta-human chorionic gonadotropin (hCG) levels are essential both in the diagnosis and in the follow-up. There are high rates of complete responses and long-term survivors, because of the excellent chemosensitivity of these tumours.
