Advanced renal cell carcinoma management: the Latin American Cooperative Oncology Group (LACOG) and the Latin American Renal Cancer Group (LARCG) consensus update.

Purpose: Renal cell carcinoma is an aggressive disease with a high mortality rate. Management has drastically changed with the new era of immunotherapy, and novel strategies are being developed; however, identifying systemic treatments is still challenging. This paper presents an update of the expert panel consensus from the Latin American Cooperative Oncology Group and the Latin American Renal Cancer Group on advanced renal cell carcinoma management in Brazil.

PD-L1 gene amplification and focality: relationship with protein expression.

PD-L1 (CD274) amplification occurs in a small subset of malignancies and may predict anti-PD-1/PD-L1 immunotherapy responsiveness. We hypothesized that both copy number (CN) and focality of cancer-related PD-L1 amplifications impact protein expression, and, thus, analyzed solid tumors that underwent comprehensive genomic profiling between March 2016 and February 2022 at Foundation Medicine. PD-L1 CN alterations were detected using a comparative genomic hybridization-like method.

Multicenter Database of Patients with Germ-Cell Tumors: A Latin American Cooperative Oncology Group Registry (LACOG 0515).

Introduction: Germ-cell tumors (GCTs) are the most common malignancy in young men. There is a paucity of data on GCTs in developing countries. LACOG 0515 study aimed to evaluate clinical characteristics and treatment outcomes in patients with GCTs from Brazilian cancer centers.

Cardiovascular toxicity following immune checkpoint inhibitors: A systematic review and meta-analysis.

Background: Immune checkpoint inhibitors may be associated with multiple immune-related toxicities. Cardiovascular adverse effects are underreported in clinical trials.

Methods: We conducted a systematic review and meta-analysis to evaluate cardiovascular adverse effects incidence among patients with solid tumors receiving immune checkpoint inhibitors in randomized clinical trials and the relative risk of presenting these effects compared to placebo or best supportive care.

Pembrolizumab plus axitinib and nivolumab plus ipilimumab as first-line treatments of advanced intermediate- or poor-risk renal-cell carcinoma: a number needed to treat analysis from the Brazilian private perspective.

Background: Considering clinical benefits of new combination therapies for metastatic renal-cell carcinoma (mRCC), this study aims to calculate the number needed to treat (NTT) and the cost of preventing an event (COPE) for pembrolizumab plus axitinib (P + A), and nivolumab plus ipilimumab (N + I) as first-line treatments, from the Brazilian private perspective.

Methods: Overall survival (OS) and progression-free survival (PFS) data for intermediate- and poor-risk groups were obtained from KEYNOTE-426 and CHECKMATE-214 trials for P + A and N + I, respectively, versus sunitinib as mRCC first-line treatment.

Results: Considering a 12-month time horizon, 6 patients should be treated with P + A to prevent one death with sunitinib use, resulting in a COPE of 3,773,865 BRL.

Advanced renal cell carcinoma (RCC) management: an expert panel recommendation from the Latin American Cooperative Oncology Group (LACOG) and the Latin American Renal Cancer Group (LARCG).

Purpose: The outcome of RCC has improved considerably in the last few years, and the treatment options have increased. LACOG-GU and LARCG held a consensus meeting to develop guidelines to support the clinical decisions of physicians and other health professionals involved in the care of RCC patients.

Methods: Eighty questions addressing relevant advanced RCC treatments were previously formulated by a panel of experts.

Impact of the biomarker enrichment strategy in drug development.

Introduction: Recently, new oncology therapies were developed using a biomarker for patient selection. In the era of cancer genomics, this paradigm is expected to increase. Most cytotoxic chemotherapies and other oncological treatments were historically approved without a biomarker.

Renal cell cancer treatment: an expert panel recommendation from the Latin American cooperative group-genitourinary and the Latin American renal cancer group: focus on surgery.

Background: Renal cell cancer (RCC) is one of the 10 most common cancers in the world, and its incidence is increasing, whereas mortality is declining only in developed countries. Therefore, two collaborative groups, The Latin American Oncology Cooperative Group-Genitourinary Section (LACOG-GU) and the Latin American Renal Cancer Group (LARCG), held a consensus meeting to develop this guideline.

Methods: Issues (134) related to the treatment of RCC were previously formulated by a panel of experts.

An appraisal of drug development timelines in the Era of precision oncology.

The effects of incorporating a biomarker-based (personalized or precision) selection strategy on drug development timelines for new oncology drugs merit investigation. Here we accessed documents from the Food and Drug Administration (FDA) database for anticancer agents approved between 09/1998 and 07/2014 to compare drugs developed with and without a personalized strategy. Sixty-three drugs were included (28 [44%] personalized and 35 [56%] non-personalized).
