Monteiro AR, Conde RS, Basto R, Sclafani F, Deleporte A, Hendlisz A, Dal Lago L. Targeted agents in older patients with gastrointestinal cancers - An overview. J Geriatr Oncol 2021; 12:1240-1252. [PMID: 34226158 DOI: 10.1016/j.jgo.2021.06.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2021] [Revised: 06/12/2021] [Accepted: 06/25/2021] [Indexed: 12/24/2022]
Abstract
Targeted agents have been increasingly used in different malignancies and are associated with improved survival outcomes, including gastrointestinal cancers. Their use in the treatment of older patients is appealing given their favorable toxicity profile. In the last years, this subgroup of patients has been attracting increased interest given their representativeness and specific clinical needs. Nonetheless, the lack of data on efficacy and safety of standard treatments in older patients hinders proper evidence-based decision-making, leaving most therapeutic recommendations to be extrapolated from registration trials with low representation of older and frail patients. However, even if most decisions regarding the use of targeted agents in older patients with gastrointestinal cancer remain guided by subanalyses of large trials, data from recent older adult-specific trials are beginning to emerge, particularly in colorectal cancer. This review aims to summarize the existing evidence on treatment of older patients with gastrointestinal carcinomas (colon and rectum, stomach, esophagus, liver, and pancreas) with targeted agents (cetuximab, panitumumab, bevacizumab, ramucirumab, aflibercept, regorafenib, encorafenib, trastuzumab, sorafenib, lenvatinib, cabozantinib, erlotinib, olaparib), and place the evidence in a geriatric oncology perspective.

Abstract
The elderly form a very heterogeneous group in relation to their general health state, degree of dependence, comorbidities, performance status, physical reserve and geriatric situation, so cancer treatment in the older patient remains a therapeutic challenge. The physiological changes associated with aging increase the risk of developing a serious toxicity induced by chemotherapy treatment, as well as other undesirable consequences as hospitalizations, dependence and non-compliance with treatment, that can negatively affect survival, quality of life and treatment efficacy. The use of hematopoietic growth factors and other active supportive interventions in the elderly can help prevent and/or alleviate these toxicities. However, we have little data on the efficacy and tolerance of support treatments in the older patient. The objective of this work is to review the most frequent toxicities of oncological treatments in the elderly and their management.

Abstract
PURPOSE Assess patient- and clinical-related variables associated with targeted cancer treatments (TTs) for adults ≥85 years of age. RATIONALE TTs have pathway-specific side effects that negatively affect QoL and medication adherence, which may reduce TT efficacy. Research has not focused on patients aged ≥85 years; therefore, the scope of TT use in this age group is not understood. METHODS We conducted an electronic medical record review to identify individuals ≥85 years treated with TT. RESULTS The sample (N = 295) was 53.5% male, 41% married/partnered, and 73.7% Caucasian. Common cancer types included breast (26.3%), prostate (31.3%), and leukemia (14.1%). Only one-third (n = 98) of the sample had TT side effects noted in their patient chart. CONCLUSIONS Patients aged ≥85 years took similar TTs and experienced similar side effects as reported by research of younger patients; however, symptom experience was not well-reported.

Clinical pharmacology of oncology agents in older adults: A comprehensive review of how chronologic and functional age can influence treatment-related effects. J Geriatr Oncol 2018; 10:4-30.

Abstract
Unique challenges exist when managing older adults with cancer. Associations between cancer and age-related physiologic changes have a direct impact on pharmacokinetics and pharmacodynamics of cancer therapies and can affect drug dosing, dose intensity, efficacy, safety and quality of life. The breadth and depth of these issues, however, have not been fully evaluated because the majority of clinical trials have focused on a younger and healthier population. As a consequence, little information is available to support clinicians in making evidence-based decisions regarding treatment with cancer therapies in older adults, especially those over age 75. Prior clinical pharmacology reviews summarized the literature on how age-related physiologic changes can influence and affect conventional and targeted anti-cancer treatments. Our article provides an updated review with expanded information that includes small molecule kinase inhibitors, monoclonal antibodies, immunotherapies, hormonal, conventional, and miscellaneous agents. Additionally, our article integrates how functional age, determined by the geriatric assessment (GA), can also influence treatment-related effects and health outcomes. Broadening cancer therapy trials to capture not only chronologic age but also functional age would allow clinicians to better identify subsets of older adults who benefit from treatment versus those most vulnerable to morbidity and/or mortality.

Abstract
Cancer is a disease associated with ageing. Increased life expectancy means that cancer in older adults is becoming an increasingly common problem. There are unique issues to consider when making decisions about cancer treatment in older populations. Unfortunately, however, this group is still under-represented in clinical trials for new cancer therapies meaning there are less evidence-based data to guide management. This article aims to look at how we can optimise the cancer treatment for older patients with a focus on systemic anti-cancer therapy and addressing particular issues around patient selection, improving treatment tolerance and use of newer agents with different toxicity profiles.

Abstract
Patients ≥65 years with cancer remain underrepresented in clinical trials, particularly in phase I clinical trials. We analyzed the clinical course of patients ≥65 years treated on phase I clinical trials with particular emphasis on toxicities. We identified 347 consecutive patients ≥65 years with advanced cancer in our phase I clinic from 01/2004-12/2009 and analyzed disease characteristics, toxicities, survival and response. Overall, 251 patients received a targeted agent, of whom 241 (96%) received an investigational, non-FDA-approved drug. Clinical benefit (complete response + partial response + stable disease ≥ 6 months) was noted in 61 patients (18%). Eighty-nine patients (26%) had grade 3/4 toxicity, commonly hematologic, including 6 dose-limiting toxicities and 1 treatment-related death (<0.01%). Median overall survival from first Phase I Clinic visit was 8.8 months (95% CI: 7.8-10.6); median time to treatment failure was 1.9 months (95% CI: 1.8-2.1). Multivariable analyses revealed 4 indicators of lack of clinical benefit (liver metastases, performance status [PS] >1, prior radiation, ≥5 prior treatments; p <0.0001). Patients age 70-79 years had a greater risk of grade 3/4 toxicities when treated with combinations (≥2 drugs) compared to monotherapy (p = 0.006). Predictors of shorter time to treatment failure and overall survival included PS >1, thrombocytosis, >2 metastatic sites, and elevated lactate dehydrogenase (p <0.05). Our results suggest that phase I clinical trials are well tolerated in patients ≥65 years. Additionally, we identified risk factors that may facilitate patient selection for clinical trial participation.

Abstract
Ovarian cancer is the seventh most common cancer in women worldwide and accounts for nearly 4% of all new cases of cancer in women. Almost half of all patients with ovarian cancer are over the age of 65 at diagnosis, and over 70% of deaths from ovarian cancer occur in this same age group. As the population ages, the number of older women with ovarian cancer is increasing. Compared to younger women, older women with ovarian cancer receive less surgery and chemotherapy, develop worse toxicity, and have poorer outcomes. They are also significantly under-represented in clinical trials and thus application of standard treatment regimens can be challenging. Performance status alone has been shown to be an inadequate tool to predict toxicity of older patients from chemotherapy. Use of formal geriatric assessment tools is a promising direction for stratifying older patients on trials. Elderly-specific trials, adjustments to the eligibility criteria, modified treatment regimens, and interventions to decrease morbidities in the vulnerable older population should be encouraged.

Abstract
The elderly population with cancer is increasing worldwide. Currently, the median age at lung cancer diagnosis is approximately 70 years. Clinicians are increasingly dealing with a population of elderly non-small-cell lung cancer patients characterised by relevant co-morbidities and ageing-related characteristics, making treatment choice more challenging. Robust evidence demonstrated that activating mutations in the epidermal growth factor receptor (EGFR) gene are the best predictor for sensitivity to EGFR tyrosine kinase inhibitors. Nine large phase III trials conducted in both the Asian and Caucasian populations demonstrated that gefitinib, erlotinib and afatinib are superior to standard platinum-based chemotherapy as front-line treatment and subgroup analyses confirmed the superiority of erlotinib or gefitinib over chemotherapy in the second-line setting. Although no large phase III trials have been specifically conducted in EGFR mutation-positive (EGFR (mut+)) elderly non-small-cell lung cancer patients, available data, coming from subgroup analysis, retrospective series or small prospective phase II trials, replicated in the elderly the results observed in the general population, thus suggesting that age per se does not represent a criterion for treatment selection. In addition, the favourable toxicity profile of EGFR-tyrosine kinase inhibitors makes these agents the preferred option in such a group of patients, for which concomitant medications are often required.

Abstract
In the elderly population, the accelerated and blastic phases of chronic myeloid leukemia (CML) are difficult to treat, not just because of the higher chance of acquired mutations than in younger individuals, but because of additional associated co-morbidities. Tyrosine kinase inhibitors are well-established in the treatment of the chronic phase of CML, and their use in advanced phases is ever-increasing. Elderly patients who are still eligible candidates for transplant can undergo reduced-intensity transplants from related or unrelated donors after reverting to chronic phase. Post-transplantation, these patients require adequate monitoring and therapy to prevent relapses. Newer modalities of treatment or interventions are urgently required in this complex group of patients.

Abstract
Cancer is a disease of aging. With the aging of the population and the improved survival of cancer patients, rehabilitation of older cancer survival is an increasingly common problem. DEFINITION AND ASSESSMENT OF AGING Age may be constructed as a progressive reduction in functional reserve of multiple organ systems leading to decreased life expectancy and reduced stress tolerance. Physiologic age may be different from chronologic age and is best assessed with a comprehensive geriatric assessment (CGA). The goals of cancer treatment in the older aged person include prolongation of active life expectancy that is prevention of functional dependence. CANCER CONDITION IN WHICH REHABILITATION OF OLDER INDIVIDUALS MAY BE NEEDED Cancer and cancer treatment may accelerate physiologic aging. Rehabilitation is especially necessary in the case of curable malignancies or malignancies for which a prolonged survival is likely. REHABILITATION NEEDS IN OLDER CANCER SURVIVORS Long-term complications of cancer treatment that may compromise life expectancy and functional independence include fatigue cognitive decline and peripheral neuropathy. This paper reviews the risk factors and the management of these complications. CONCLUSIONS The number of older cancer survivors is expected to increase with the aging of the population. Prevention and management of fatigue, cognitive decline and peripheral neuropathy appear as the most important issue to prolong the active life expectancies of these individuals.

Abstract
The incidence of colorectal and breast cancer is growing among the 550 million living people aged 65 or older. Bevacizumab was the first anti-angiogenic agent approved for the treatment of the advanced phase of these cancers. Although older chronological age still hampers the use of modern treatments, there is a widespread awareness that chronological and physiological (i.e. functional) ages may largely differ, and that seniority itself should not be a stringent limit for the introduction of anti-angiogenics. However, the use of bevacizumab in the general older population is questionable. There is limited evidence of a favorable risk-to-benefit ratio, with efficacy data deriving from clinical trials that selected only elderly patients in rather good health. While summarizing the recent advances, this review highlights specific clinical features characterizing those older patients who may benefit the most from receiving bevacizumab.

Abstract
Substantial progress has been made in the management of breast cancer by targeting HER2 and VEGF pathways. Although the efficacy and safety of target therapy in breast cancer have been established, no specific phase III trial has addressed these issues in the elderly population and the only data available derive from subanalyses or retrospective series. The aim of this review is to summarize the available evidence in this special population and to encourage further well designed studies in elderly breast cancer patients.
