Background: A standard treatment for fit, older patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) is yet to be established. In the previous EXTREME trial, few older patients were included. We aimed to evaluate the efficacy and tolerance of an adapted EXTREME regimen in fit, older patients with recurrent or metastatic HNSCC.

Article Synopsis
  • There is currently no reliable biomarker for predicting the effectiveness of EGFR inhibitors in head and neck squamous cell carcinoma (HNSCC), leading researchers to investigate afatinib, a promising treatment.
  • In a trial with 61 patients, afatinib showed a high metabolic response, with responders demonstrating specific biomarker expressions (higher pERK1/2 and lower pHER4 and pRB1 levels).
  • Further analysis indicated that responders had more tumor-infiltrating B cells, while non-responders had an overrepresentation of NF-kappa B signaling in their gene expression, suggesting potential new biomarkers for afatinib efficacy that require more research.*

Background: In metastatic seminoma, a strategy is needed for selecting patients for less intensive chemotherapy, to limit toxicities.

Objective: To assess whether men with good-prognosis metastatic seminoma could be treated with two cycles of etoposide-cisplatin (EP) followed by only one cycle of carboplatin (CARBO) based on negative interim fluorodeoxyglucose positron emission tomography (FDG-PET)/computed tomography (CT).

Design, Setting, And Participants: A nonrandomised, multicentre, phase 2 trial was conducted (NCT01887340).

Primary tumour response may impact therapeutic strategies in metastatic renal cell carcinoma (mRCC) but remains unknown in the era of immune checkpoint inhibitors. We aimed to describe the response of the primary tumour in patients who did not undergo upfront cytoreductive nephrectomy (uCN) and were treated with nivolumab in the GETUG-AFU-26 NIVOREN phase 2 trial. Primary tumour response was prospectively assessed, as well as the overall response rate (ORR), progression-free survival (PFS), and overall survival (OS).

Background: The optimal therapeutic strategies for patients with metastatic hormone-sensitive prostate cancer (mHSPC) followed by metastatic castrate-resistant prostate cancer (mCRPC), in terms of cost and effectiveness, remains unknown. This study aims to compare the cost-effectiveness of various potential strategies, from the start of first-line treatment in mHSPC to the death of the patients.

Methods: Two Markov decision-analysis models were developed, one for cohort A "asymptomatic/mildly symptomatic patients in mCRPC", and one for cohort B "symptomatic patients in mCRPC".

Background: In Europe, induction chemotherapy (ICT) followed by radiotherapy is preferred to conventional chemoradiotherapy to avoid total laryngectomy in patients with laryngeal/hypopharyngeal cancer. In comparison with conventional radiotherapy, bioradiotherapy with cetuximab significantly improves locoregional control rates (LCRs) and overall survival (OS) without any increase in unmanageable toxicity.

Methods: Patients included had untreated non-metastatic stage III-IV laryngeal/hypopharyngeal invasive squamous cell carcinoma.

Purpose: Complete remission (CR) is uncommon during treatment for metastatic renal cell carcinoma (mRCC) with tyrosine kinase inhibitors (TKIs), but it may occur in some patients. It remains a matter of debate whether therapy should be continued after CR.

Methods: A multicenter, retrospective analysis of a series of patients with mRCC who obtained CR during treatment with TKIs (sunitinib or sorafenib), either alone or with local treatment (surgery, radiotherapy, or radiofrequency ablation), was performed.
