First-line immunotherapy in advanced non-small-cell lung cancer patients with ECOG performance status 2: results of an International Expert Panel Meeting by the Italian Association of Thoracic Oncology.

ABSTRACT:

Background

Immunotherapy represents the standard of care in the first-line treatment of advanced non-small-cell lung cancer (NSCLC), either as monotherapy in high programmed death-ligand 1 (PD-L1)-positive tumors (≥50%) or in combination with platinum-based chemotherapy regardless of PD-L1 status. However, most pivotal clinical trials of immune checkpoint inhibitors (ICIs) did not include patients with Eastern Cooperative Oncology Group (ECOG) performance status (PS) 2. Hence, a consensus is lacking on the safety and efficacy of ICIs in this specific subgroup of patients.

Materials and methods

A virtual International Expert Panel took place in July 2021 with the aim of reviewing the available evidence on the use of ICIs in NSCLC patients with ECOG PS 2, both in clinical practice and in a research setting.

Results

All panelists expressed concern about the applicability of currently available PS scales to evaluate patients for ICI treatment. The panelists agreed that, though limited, the available data support the safety of single-agent immunotherapy in PS 2 NSCLC patients, whereas concern was raised on the safety of ICI combinations, mainly related to chemotherapy and/or anti-cytotoxic T-lymphocyte-associated antigen 4 toxicity. On the basis of reviewed data, ICI efficacy may be speculated in PS 2 NSCLC patients; however, PS 2 remains a negative prognostic category as compared to PS 0-1 in patients treated with ICI, as it is for chemotherapy. The panelists defined high, medium and low priorities in clinical research. High priority was attributed to the inclusion of PS 2 patients in prospective clinical trials and the specific evaluation of combined ICI treatments with attenuated chemotherapy doses.

Conclusions

Based on the current evidence, the panelists outlined the major limitations affecting PS 2 patients with NSCLC and reached common considerations on the feasibility, safety and effectiveness of ICI monotherapy and ICI combinations in the first-line setting.

Project description:IntroductionThe incidence of prostate cancer in Japan continues to increase, necessitating the continued development of effective therapies and strategies. Recent advances in treatments have improved the prognosis of metastatic disease and highlighted the importance of treating bone metastases to reduce the incidence of skeletal complications and improve patients' quality of life. With the increasing number of treatment options that have become available, including bone-targeted therapy with the alpha emitter radium-223 dichloride (Ra-223), Japanese clinicians are faced with making difficult decisions on the choice of optimal treatment strategy. In such situations, guidance based on expert opinions can be beneficial.MethodsA panel meeting of 27 Japanese experts in the management of prostate cancer was held to share opinions and to establish consensus recommendations on key clinical questions. Panelists were asked to vote on more than 40 questions pertinent to prostate cancer, and the answers helped guide a comprehensive discussion.ResultsThe panel reached a consensus on key topics related to the optimal treatment strategy for Ra-223 therapy, namely, that patients with symptomatic, metastatic castration-resistant prostate cancer (CRPC) would benefit most from the use of this agent and that this treatment therapy should be provided before chemotherapy. Other topics that achieved consensus included: monitoring for osteoporosis and providing treatment if necessary during androgen deprivation therapy; performing magnetic resonance imaging in the presence of discrepancies in bone scintigram and computed tomography scans; monitoring alkaline phosphatase during CRPC treatment; using osteoclast-targeting in patients with CRPC with bone metastases; and using osteoclast-targeted agents combined with Ra-223.ConclusionThese consensus recommendations and the updated information which became available subsequent to the panel meeting included here provide useful information for clinicians to aid in designing optimal treatment strategies for their patients.FundingBayer Yakuhin Ltd.

Project description:ImportanceThere is currently no guidance on how to approach surveillance mammography for older breast cancer survivors, particularly when life expectancy is limited.ObjectiveTo develop expert consensus guidelines that facilitate tailored decision-making for routine surveillance mammography for breast cancer survivors 75 years or older.EvidenceAfter a literature review of the risk of ipsilateral and contralateral breast cancer events among breast cancer survivors and the harms and benefits associated with mammography, a multidisciplinary expert panel was convened to develop consensus guidelines on surveillance mammography for breast cancer survivors 75 years or older. Using an iterative consensus-based approach, input from clinician focus groups, and critical review by the International Society for Geriatric Oncology, the guidelines were refined and finalized.FindingsThe literature review established a low risk for ipsilateral and contralateral breast cancer events in most older breast cancer survivors and summarized the benefits and harms associated with mammography. Draft mammography guidelines were iteratively evaluated by the expert panel and clinician focus groups, emphasizing a patient's risk for in-breast cancer events, age, life expectancy, and personal preferences. The final consensus guidelines recommend discontinuation of routine mammography for all breast cancer survivors when life expectancy is less than 5 years, including those with a history of high-risk cancers; consideration to discontinue mammography when life expectancy is 5 to 10 years; and continuation of mammography when life expectancy is more than 10 years. Individualized, shared decision-making is encouraged to optimally tailor recommendations after weighing the benefits and harms associated with surveillance mammography and patient preferences. The panel also recommends ongoing clinical breast examinations and diagnostic mammography to evaluate clinical findings and symptoms, with reassurance for patients that these practices will continue.Conclusions and relevanceIt is anticipated that these expert guidelines will enhance clinical practice by providing a framework for individualized discussions, facilitating shared decision-making regarding surveillance mammography for breast cancer survivors 75 years or older.
