Pseudoprogression in a patient with hepatocellular carcinoma treated with immunotherapy plus bevacizumab.

A 62-year-old male with hepatocellular carcinoma on a healthy liver underwent surgery in April 2022. Five months after, the patient complained of abdominal pain, with an alpha-fetoprotein (AFP) level exceeding 9000 ng/ml, and CT images showed liver metastases and multiple lung metastases, so treatment with immunotherapy atezolizumab plus bevacizumab was started in September 2022. After four cycles, hyperprogression was observed in liver and lung metastases at first CT evaluation.

Real-world data of atezolizumab in patients with previously treated locally advanced or metastatic urothelial bladder cancer.

Background: Clinical trials of atezolizumab for locally advanced or metastatic urothelial bladder cancer (mUBC) report controversial efficacy data. Furthermore, real-world evidence about this use is limited.

Aim: We aimed to evaluate the effectiveness of atezolizumab in a real-world population with mUBC, to explore effectiveness with regard to selected poor prognostic criteria such as performance status by Eastern Oncology Cooperative Group (ECOG), hemoglobin levels and liver metastases, and to determine the safety profile of atezolizumab.

Prospective Assessment of Bone Metabolism Biomarkers and Survival in Metastatic Castration-resistant Prostate Cancer Patients Treated with Radium-223: The PRORADIUM Study.

Background: Radium-223 is an active therapy option for bone metastatic castration-resistant prostate cancer (mCRPC). The lack of adequate biomarkers for patient selection and response assessment are major drawbacks for its use.

Objective: To assess the prognostic value of bone metabolism biomarkers (BMBs) in ra-223-treated mCRPC patients.

The Challenge of Managing Bladder Cancer and Upper Tract Urothelial Carcinoma: A Review with Treatment Recommendations from the Spanish Oncology Genitourinary Group (SOGUG).

Bladder cancer is the fourth most common cancer in men and the ninth most common in women in the Western world. The management of bladder carcinoma requires a multidisciplinary approach. Optimal treatment depends on several factors, including histology, stage, patient status, and possible comorbidities.

PROREPAIR-B: A Prospective Cohort Study of the Impact of Germline DNA Repair Mutations on the Outcomes of Patients With Metastatic Castration-Resistant Prostate Cancer.

Purpose: Germline mutations in DNA damage repair (DDR) genes are identified in a significant proportion of patients with metastatic prostate cancer, but the clinical implications of these genes remain unclear. This prospective multicenter cohort study evaluated the prevalence and effect of germline DDR (gDDR) mutations on metastatic castration-resistance prostate cancer (mCRPC) outcomes.

Patients And Methods: Unselected patients were enrolled at diagnosis of mCRPC and were screened for gDDR mutations in 107 genes.

Pazopanib: Evidence review and clinical practice in the management of advanced renal cell carcinoma.

Background: Pazopanib is indicated in the first-line treatment of metastatic renal cell cancer (mRCC). The aim of this study was to review the efficacy, safety, and pharmacokinetics of pazopanib and see how these aspects are linked to clinical practice.

Methods: A non-exhaustive systematic review was conducted according to the three topics.

Weekly cabazitaxel plus prednisone is effective and less toxic for 'unfit' metastatic castration-resistant prostate cancer: Phase II Spanish Oncology Genitourinary Group (SOGUG) trial.

Aim: Cabazitaxel (CBZ), a novel tubulin-binding taxane, improves overall survival in metastatic castration-resistant prostate cancer (mCRPC) that progresses during or after docetaxel treatment. We have designed a phase II study to evaluate the efficacy and safety of CBZ as a weekly schedule for 'unfit' mCRPC patients after docetaxel failure.

Methods: In this single arm phase II study.

Experience with Sunitinib in metastatic renal cell carcinoma (mRCC) patients: pooled analysis from 3 Spanish observational prospective studies.

Background: A pivotal, randomized, phase III trial demonstrated a statistically significant superiority of sunitinib over interferon-α in metastatic renal cell carcinoma (mRCC) patients.

Objective: To evaluate the effectiveness and safety of sunitinib in patients with advanced or mRCC in routine clinical practice.

Methods: Retrospective pooled analysis of clinical data from three observational and prospective studies carried out between 2007 and 2011 in 33 Spanish hospitals.

Gemcitabine-erlotinib versus gemcitabine-erlotinib-capecitabine in the first-line treatment of patients with metastatic pancreatic cancer: Efficacy and safety results of a phase IIb randomised study from the Spanish TTD Collaborative Group.

Background: Gemcitabine and erlotinib have shown a survival benefit in the first-line setting in metastatic pancreatic cancer (mPC). The aim of this study was to assess whether combining capecitabine (C) with gemcitabine + erlotinib (GE) was safe and effective versus GE in patients with mPC.

Patients And Methods: Previously untreated mPC patients were randomised to receive G (1000 mg/m, days 1, 8, 15) + E (100 mg/day, days 1-28) + C (1660 mg/m, days 1-21) or GE, q4 weeks, until progression or unacceptable toxicity.

Impact on clinical practice of the implementation of guidelines for the toxicity management of targeted therapies in kidney cancer. The protect-2 study.

Background: The impact of such recommendations after their implementation of guidelines has not usually been evaluated. Herein, we assessed the impact and compliance with the Spanish Oncology Genitourinary Group (SOGUG) Guidelines for toxicity management of targeted therapies in metastatic renal cell carcinoma (mRCC) in daily clinical practice.

Methods: Data on 407 mRCC patients who initiated first-line targeted therapy during the year before and the year after publication and implementation of the SOGUG guideline program were available from 34 Spanish Hospitals.
