Management of prostate cancer in older patients: updated recommendations of a working group of the International Society of Geriatric Oncology

Physical performance tests have excellent reliability in frail and non-frail patients with prostate cancer

PURPOSE

Our aim was to investigate the test-retest reliability of the 2-min walk test (2MWT), timed up and go test (TUG), and five times sit-to-stand test (FTSST) in prostate cancer (PC) patients.

METHODS

This study was conducted with 73 patients who were classified into two groups as frail and non-frail determined by the Geriatric-8 questionnaire. Patients performed the 2MWT, TUG, and FTSST tests for two times. The test-retest reliability of the 2MWT, TUG, and FTSST was assessed by calculating the intraclass correlation coefficient (ICC). The standard error of measurement (SEM95) and minimal detectable change (MDC95) values were calculated.

RESULTS

All tests showed excellent test-retest reliability for both groups (ICC(2.1) > 0.90). The SEM95 and MDC95 values of 2MWT were 3.09, 8.57, and 3.15 m, 8.73 m for frail and non-frail groups. The SEM95 and MDC95 values of TUG for the frail group were 0.6 and 1.66 and 0.43 and 1.19 for the non-frail group, respectively. The SEM95 and MDC95 values of FTST for the frail group were 0.68 and 1.88 and for the non-frail group 0.86 and 2.38.

CONCLUSIONS

The 2MWT, TUG, and FTSST showed excellent reliability in frail and non-frail older adults with PC which can be used to assess physical performance.

Comprehensive geriatric assessment predicts radiation-induced acute toxicity in prostate cancer patients

PURPOSE

The purpose of the present prospective study was to evaluate the significance of geriatric conditions measured by a comprehensive geriatric assessment (GA) for the prediction of the risk of high-grade acute radiation-induced toxicity.

METHODS

A total of 314 prostate cancer patients (age ≥ 65 years) undergoing definitive radiotherapy at a tertiary academic center were included. Prior to treatment, patients underwent a GA. High-grade toxicity was defined as acute toxicity grade ≥ 2 according to standard RTOG/EORTC criteria. To analyze the predictive value of the GA, univariable and multivariable logistic regression models were applied.

RESULTS

A total of 40 patients (12.7%) developed acute toxicity grade ≥ 2; high grade genitourinary was found in 37 patients (11.8%) and rectal toxicity in 8 patients (2.5%), respectively. Multivariable analysis revealed a significant association of comorbidities with overall toxicity grade ≥ 2 (odds ratio [OR] 2.633, 95% confidence interval [CI] 1.260-5.502; p = 0.010) as well as with high-grade genitourinary and rectal toxicity (OR 2.169, 95%CI1.017-4.625; p = 0.045 and OR 7.220, 95%CI 1.227-42.473; p = 0.029, respectively). Furthermore, the Activities of Daily Living score (OR 0.054, 95%CI 0.004-0.651; p = 0.022), social status (OR 0.159, 95%CI 0.028-0.891; p = 0.036), and polypharmacy (OR 4.618, 95%CI 1.045-20.405; p = 0.044) were identified as independent predictors of rectal toxicity grade ≥ 2.

CONCLUSION

Geriatric conditions seem to be predictive of the development of high-grade radiation-induced toxicity in prostate cancer patients treated with definitive radiotherapy.

Biweekly vs Triweekly Cabazitaxel in Older Patients With Metastatic Castration-Resistant Prostate Cancer: The CABASTY Phase 3 Randomized Clinical Trial

Importance

Many patients 65 years or older with metastatic castration-resistant prostate cancer (mCRPC) are denied taxane chemotherapy because this treatment is considered unsuitable.

Objective

To determine whether biweekly cabazitaxel (CBZ), 16 mg/m2 (biweekly CBZ16), plus prophylactic granulocyte colony-stimulating factor (G-CSF) at each cycle reduces the risk of grade 3 or higher neutropenia and/or neutropenic complications (eg, febrile neutropenia, neutropenic infection, or sepsis) compared with triweekly CBZ, 25 mg/m2 (triweekly CBZ25), plus G-CSF (standard regimen).

Design, Setting, and Participants

A total of 196 patients 65 years or older with progressive mCRPC were enrolled in this prospective phase 3 randomized clinical trial conducted in France (18 centers) and Germany (7 centers) between May 5, 2017, and January 7, 2021. All patients had received docetaxel and at least 1 novel androgen receptor-targeted agent.

Interventions

Patients were randomly assigned 1:1 to receive biweekly CBZ16 plus G-CSF and daily prednisolone (experimental group) or triweekly CBZ25 plus G-CSF and daily prednisolone (control group).

Main Outcome and Measures

The primary end point was the occurrence of grade 3 or higher neutropenia measured at nadir and/or neutropenic complications.

Results

Among 196 patients (97 in the triweekly CBZ25 group and 99 in the biweekly CBZ16 group), the median (IQR) age was 74.6 (70.4-79.3) years, and 181 (92.3%) had an Eastern Cooperative Oncology Group performance status of 0 or 1. The median (IQR) follow-up duration was 31.3 (22.5-37.5) months. Relative dose intensities were comparable between groups (median [IQR], 92.7% [83.7%-98.9%] in the triweekly CBZ25 group vs 92.8% [87.0%-98.9%] in the biweekly CBZ16 group). The rate of grade 3 or higher neutropenia and/or neutropenic complications was significantly higher with triweekly CBZ25 vs biweekly CBZ16 (60 of 96 [62.5%] vs 5 of 98 [5.1%]; odds ratio, 0.03; 95% CI, 0.01-0.08; P < .001). Grade 3 or higher adverse events were more common with triweekly CBZ25 (70 of 96 [72.9%]) vs biweekly CBZ16 (55 of 98 [56.1%]). One patient (triweekly CBZ25 group) died of a neutropenic complication.

Conclusions and Relevance

In this randomized clinical trial, compared with the standard regimen, biweekly CBZ16 plus G-CSF significantly reduced by 12-fold the occurrence of grade 3 or higher neutropenia and/or neutropenic complications, with comparable clinical outcomes. The findings suggest that biweekly CBZ16 regimen should be offered to patients 65 years or older with mCRPC for whom the standard regimen is unsuitable.

Quality of life, effectiveness, and safety of aflibercept plus FOLFIRI in older patients with metastatic colorectal cancer: An analysis of the prospective QoLiTrap study

INTRODUCTION

Colorectal cancer (CRC) mainly affects older patients. The pivotal VELOUR phase III trial of aflibercept plus FOLFIRI in metastatic CRC (mCRC) included only 5.9% of patients aged ≥75 years. Herein, we report a preplanned analysis from QoLiTrap, a large prospective observational study evaluating the impact of age on quality of life (QoL), effectiveness, and safety of aflibercept plus FOLFIRI in daily clinical practice in Europe.

MATERIALS AND METHODS

Enrolled patients had progressive mCRC, had failed a prior oxaliplatin-based regimen, and had received aflibercept (4 mg/kg) plus FOLFIRI every two weeks until disease progression, death, unacceptable toxicity, or physician/patient decision. Analyses were performed by age classes (<60, 60-64, 65-69, 70-74, and ≥ 75 years). The primary endpoint was the percentage of patients whose global health status (GHS) of the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) was maintained (i.e., no worsening from baseline by at least 5% over a 12-week treatment). Secondary endpoints included tumor objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and safety.

RESULTS

Overall, 1277 patients (<60 years, n = 327; 60-64 years, n = 231; 65-69 years, n = 227; 70-74 years, n = 259; and ≥ 75 years, n = 233) were treated, of whom 872 were evaluable for QoL. GHS was maintained in 36.5%, 41.6%, 38.9%, 41.8%, and 44.8% of patients aged <60, 60-64, 65-69, 70-74, and ≥ 75 years, respectively. Age did not influence PFS (median 7.8 months), OS (median 14.4 months), or ORR (20.8%). Number of cycles, dose delays for any cause, and dose reductions for adverse events (AEs) were comparable between age classes. Grade ≥ 3 AEs occurred in 47.7%, 51.9%, 51.5%, 55.2%, and 55.8% of patients aged <60, 60-64, 65-69, 70-74, and ≥ 75 years, respectively. The main grade ≥ 3 AEs were hypertension (11.2%) and diarrhea (9%) in patients aged ≥75 years.

DISCUSSION

The results suggest that aflibercept plus FOLFIRI maintains QoL and retains its activity, including a high objective tumor response, regardless of age and treatment line. In fit older patients, the safety profile seems manageable, with no new safety signals.

Safety and Efficacy of [177Lu]-PSMA-I&T Radioligand Therapy in Octogenarians with Metastatic Castration-Resistant Prostate Cancer: Report on 80 Patients over the Age of 80 Years

¹⁷⁷Lu-labeled prostate-specific membrane antigen (PSMA) radioligand therapy (RLT) is a new treatment option for metastatic castration-resistant prostate cancer (mCRPC). Its low toxicity profile favors use in elderly patients or in patients with critical comorbidities. The purpose of this analysis was to evaluate the efficacy and safety of [¹⁷⁷Lu]-PSMA RLT in mCRPC patients at least 80 y old. Methods: Eighty mCRPC patients at least 80 y old underwent [¹⁷⁷Lu]-PSMA-I&T RLT and were retrospectively selected. The patients were previously treated by androgen receptor-directed therapy, received taxane-based chemotherapy, or were chemotherapy-ineligible. The best prostate-specific antigen (PSA) response was calculated, as well as clinical progression-free survival (cPFS) and overall survival (OS). Toxicity data were acquired until 6 mo after the last treatment cycle. Results: Of 80 patients, 49 (61.3%) were chemotherapy-naïve and 16 (20%) had visceral metastases. The median number of previous mCRPC treatment regimens was 2. In total, 324 cycles (median, 4 cycles; range, 1-12) with a median cumulative activity of 23.8 GBq (interquartile range, 14.8-42.2) were applied. A PSA decline of 50% was achieved in 37 (46.3%) patients. Chemotherapy-naïve patients showed higher 50% PSA response rates than chemotherapy-pretreated patients (51.0% vs. 38.7%, respectively). Overall, median cPFS and OS were 8.7 and 16.1 mo, respectively. The median cPFS and OS of chemotherapy-naïve patients were significantly longer than those of chemotherapy-pretreated patients (10.5 vs. 6.5 mo and 20.7 vs. 11.8 mo, respectively, P < 0.05). A lower hemoglobin level and higher lactate dehydrogenase level at baseline were independent predictors of shorter cPFS and OS. Treatment-emergent grade 3 toxicities were anemia in 4 patients (5%), thrombocytopenia in 3 patients (3.8%), and renal impairment in 4 patients (5%). No nonhematologic grade 3 and no grade 4 toxicities were observed. The most frequent clinical side effects were grade 1-2 xerostomia, fatigue, and inappetence. Conclusion: [¹⁷⁷Lu]-PSMA-I&T RLT in mCRPC patients at least 80 y old is safe and effective, comparable to previously published data on non-age-selected cohorts with a low rate of high-grade toxicities. Chemotherapy-naïve patients showed a better and longer response to therapy than taxane-pretreated patients. [¹⁷⁷Lu]-PSMA RLT seems to be a meaningful treatment option for older patients.

Item analysis of G8 screening in uro-oncologic geriatric patients

INTRODUCTION/BACKGROUND

The G8 score is a widespread screening tool for geriatric frailty in oncology. The aim of this study was to evaluate the scores and relevance of G8 items in a standard screening of geriatric patients with uro-oncologic diseases to better understand the results of the assessment.

METHODS

Eighty-two consecutive uro-oncologic geriatric patients aged 75 years and older were evaluated. All patients underwent a G8 screening that consisted of 8 items. Patients with a G8 score above 14 were considered geriatric "fit", while others were considered to be "frail". Overall results and single item scores were evaluated. Clinical data were gathered from patients' charts.

RESULTS

The mean age of the patients was 82 years (min. 75-max. 102). In 36 of the patients, the G8 score indicated "no-frailty", and in 46 patients, the G8 score indicated "frailty". The mean G8 score was 12.9 (min 4-max 17 pts). Item analysis revealed that points were most often lost in items H (polypharmacy), P (comparison of health status to peers) and Age. Fifty-nine, 56 and 52 patients lost points on item Age, item H and item P, respectively. In contrast, the majority of patients reached the maximum score for nutritional items [i.e., items A (food intake), B (weight loss) and F (body mass index (BMI))]. For item A, 73 patients reached the maximum score; for item B, 62 patients reached the maximum score; and for item F, 72 patients reached the maximum score. There were no differences in this distribution pattern when comparing tumour entities, sex, and patients with local vs. metastatic disease.

CONCLUSION

The present study revealed a high percentage of suspicious test results. Potential reasons for these findings include the low threshold of the G8 overall score and the fact that in some items, points were easily lost. Modifications of the test should be considered.

Analysis of Frailty Syndrome in Men with Metastatic Prostate Cancer: A Scoping Review

Most patients with metastatic prostate cancer (mPCa) are older. In addition, current geriatric oncology guidelines suggest that all cancer patients aged over 70 years should undergo a comprehensive geriatric assessment (CGA), with the identification of frailty syndrome being crucial for clinical decisions. Frailty can be associated with lower quality of life (QoL) and interfere with the feasibility or side effects of oncology treatments.

METHODS

We performed a systematic literature search to evaluate frailty syndrome and associated alterations related to CGA impairment by searching in different academic databases (PubMed, Embase, and Scopus). The identified articles were reviewed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

RESULTS

Of the 165 articles consulted, 7 met our inclusion criteria. Analysis of data related to frailty syndrome in patients with mPCa showed a prevalence between 30-70% depending on the tool used. Additionally, frailty was associated with other CGA assessments and QoL evaluation outcomes. In general terms, CGA scores for patients with mPCa were lower than those for patients without metastasis. Furthermore, functional QoL appeared to be worse for patients with metastasis, and global QoL (burden) was more strongly associated with frailty.

CONCLUSION

Frailty syndrome was related to a poorer QoL in patients with mPCa and its evaluation should be considered in clinical decision-making and when choosing the most appropriate active treatment, if any, to increase survival.

A systemic review of taxanes and their side effects in metastatic breast cancer

Taxanes-containing chemotherapy constitutes an essential backbone for both early and metastatic breast cancer (mBC). However, the two major taxane drugs—paclitaxel and docetaxel—have distinct safety profiles. In this review, we summarize the safety outcome and management following treatment with both taxanes from selected clinical trials. We utilized PubMed to perform literature search before April 2021. Five phase III randomized controlled trials with reports of individual taxane adverse events (AEs) were included in this review. Grade 3/4 AEs were summarized and discussed extensively. The rates of grade 3/4 neutropenia were higher with docetaxel than with paclitaxel. For non-hematologic grade 3/4 AEs, peripheral neuropathy was more frequent with paclitaxel while fluid retention was more frequent with docetaxel. Compared to paclitaxel, docetaxel had a higher rate of grade 3/4 gastrointestinal AEs. Grade 3/4 myalgia were generally comparable between the two taxanes. Except for neutropenia, the incidence rate of grade 3/4 AEs of taxanes was generally manageable. Peripheral neuropathy was more common with paclitaxel while grade 3/4 neutropenia was more common with docetaxel.

Irradiation of localized prostate cancer in the elderly: A systematic literature review

•

Oncological benefit for elderly patients with optimal treatment.

•

Elderly patients often received inadequate treatment.

•

Elderly comorbidities can influence oncological outcomes and treatment tolerance.

•

Optimal curative treatment after oncogeriatric assessment.

Purpose

To analyze the literature that addresses radiation therapy for intermediate and high-risk prostate cancer (PC) in the elderly.

Patients and methods

A PubMed literature search was conducted including articles from 01/01/2000 to 30/06/21, with the following keywords: PC, radiotherapy/brachytherapy and elderly. The analysis mainly focused on the issue of under-treatment in the elderly and the benefit/risk balance of irradiation.

Results

Of the 176 references analyzed, 24 matched the selection criteria. The definition of “elderly patient” varied from 70 to 80 years. The analysis was impacted by the inhomogeneous primary end points used in each cohort. Age was often an obstacle to radical treatment, with a subsequent risk of under-treatment, particularly in patients with a poorer prognosis. However, comparable elderly oncological outcomes were compared to younger patients, both with external beam radiotherapy alone or combined with brachytherapy boost. Late toxicity rates are low and most often comparable to younger populations. However, a urinary over- toxicity was observed in the super-elderly (>80 years) after brachytherapy boost. The use of ADT should be considered in light of comorbidities, and may even be deleterious in some patients.

Conclusion

Due to the increase in life expectancy, the management of PC in the elderly is a challenge for patients, clinicians and health insurance payers. Except for unfit men, elderly patients remain candidates for optimal curative treatment (i.e. regardless of age) after oncogeriatric assessment. More solid data from prospective trials conducted specially in this population will provide better guidance in our daily clinical practice.

Non-metastatic castration-resistant prostate cancer: management recommendations

INTRODUCTION AND OBJECTIVE

Survival and quality of life (QoL) of patients with non-metastatic castration-resistant prostate cancer (nmCRPC) deteriorate significantly when they develop metastases. New generation antiandrogens (apalutamide, enzalutamide and darolutamide) can prolong metastasis-free survival (MFS) and overall survival (OS) in these patients, maintaining their QoL.

MATERIAL AND METHODS

After the performance of a systematic review of the literature, a scientific committee reached a consensus on simple and practical recommendations to consolidate and improve the management of patients with nmCRPC in urology consultations.

RESULTS

Recommendations are made on the frequency of PSA determination and imaging tests in patients with nmCRPC. The importance of co-morbidities in patients with nmCRPC is also highlighted, and recommendations are also made on functional and QoL assessment that can be carried out during urology consultations. The efficacy, safety, and effects on QoL of new generation antiandrogens are reviewed.

CONCLUSIONS

To evaluate treatment of patients with nmCRPC, it is necessary to consider co-morbidities and QoL, in addition to age. New generation antiandrogens are a safe and effective treatment option for patients with nmCRPC. The recommendations of this review can be helpful in optimizing the management of nmCRPC patients in urology consultations.

Outcome of primary androgen deprivation therapy in super-elderly men with localized high-risk prostate cancer

The purpose of this study is to provide certain data on clinical outcome of primary androgen deprivation therapy in men over 80 years of age with localized high-risk prostate cancer. This study included 54 Japanese super-elderly men with high-risk prostate cancer treated with primary androgen deprivation therapy between 2005 and 2015. The median overall survival was 9.1 years (95% confidence interval, 8.1-10.1) and no patient died from prostate cancer. Overall, 51.9% of patients experienced any grade of adverse events following androgen deprivation therapy. Associations between clinicopathological factors including comorbidity count at initial diagnosis and overall survival were investigated. On multivariate analysis, only comorbidity count at initial diagnosis [≥2 vs. ≤1; hazard ratio, 5.34 (95% confidence interval, 1.55-18.49); P = 0.003] was an independent risk factor for overall survival. Our findings suggest that comorbidity count at initial diagnosis is robustly prognostic for overall survival. For super-elderly men with localized high-risk prostate cancer, comorbidity count at initial diagnosis should be emphasized when deciding whether primary androgen deprivation therapy is necessary or not.

Management of prostate cancer in older patients

The incidence of prostate cancer among older men has increased in many countries, including Asian countries. However, older patients are ineligible for inclusion in large randomized trials, and the existing guidelines for the management of patients with prostate cancer do not provide specific treatment recommendations for older men. Therefore, generation of evidence for older patients with prostate cancer is a key imperative. The International Society of Geriatric Oncology has produced and updated several guidelines for management of prostate cancer in older men since 2010. Regarding localized prostate cancer, both surgery and radiotherapy are considered as feasible treatment options for intermediate- and high-risk prostate cancer even in older men, whereas watchful waiting and active surveillance are useful options for a proportion of these patients. With regard to advanced disease, androgen-receptor axis targets and taxane chemotherapy are standard treatment modalities, although dose modification and prevention of adverse events need to be considered. Management strategy for older patients with prostate cancer should take cognizance of not only the chronological age but also psychological and physical condition, socio-economic status and patient preferences. Geriatric assessment and patient-reported health-related quality of life are important tools for assessing health status of older patients with prostate cancer; however, there is a paucity of evidence of the impact of these tools on the clinical outcomes. Personalized management according to the patient's health status and tumour characteristics as well as socio-economic condition may be necessary for treatment of older patients with prostate cancer.

Impact of prostate-specific antigen screening on tumor size in patients with prostate cancer in a super-aging district in Kyoto, Japan

BACKGROUND

Population-based prostate-specific antigen (PSA) screening is effective for reducing prostate cancer (PCa)-related mortality rates. In this study, we assessed biopsy-proven maximum cancer core length (MCCL) and maximum cancer diameter on magnetic resonance imaging (MRI; MCDM) in prostate biopsy and multiparametric MRI (mp-MRI) by PCa detection.

METHODS

We retrospectively assessed 214 male PCa patients and 187 PCa patients with Prostate Imaging Reporting and Data System version 2 (PI-RADS) category 3-5 lesions in pre-biopsy mp-MRI and targeted biopsy characteristics. The mean biopsy-proven MCCL and MCDM were compared among three PSA screening groups, namely the population-based PSA screening (PBS), opportunistic PSA screening (OPS), and symptomatic outpatient PSA examination (SOP) groups.

RESULTS

The median age and PSA value of the 214 participants were 75 years and 7.9 ng/mL, respectively. In the PBS, OPS, and SOP groups, the median ages were 73, 76, and 76 years, respectively (p = 0.046); PSA values were 7.2, 9.5, and 11.5 ng/mL, respectively (p < 0.001); and biopsy-proven MCCL and MCDM were significantly increased to 7, 10, and 14 mm (p < 0.001) and to 11, 15, and 17 mm (p < 0.001), respectively. In the 187 PCa patients with PI-RADS category 3-5 lesions on mp-MRI, MCDM were 11, 14, and 17 mm (p < 0.001), respectively.

CONCLUSIONS

The biopsy-proven MCCL and MCDM were significantly smaller in the PBS and OPS groups than in the SOP group, which suggests that PSA screening detected PCa earlier than in symptomatic patients. PSA screening with MRI could objectively lead to earlier diagnosis based on tumor size.

Adherence to Treatment Guidelines and Associated Survival in Older Patients with Prostate Cancer: A Prospective Multicentre Cohort Study

The guidelines on prostate cancer treatment in older men recommend evaluating the patient's underlying health status before treatment selection. We aimed to evaluate the frequency of a guideline-discordant treatment (GDT), identify factors associated with GDT, and assess the relationship between GDT and overall survival. We studied patients with prostate cancer aged 70 or older included in the ELCAPA cohort between 2010 and 2019. Multivariable logistic regression assessed GDT-associated factors. The restricted mean survival time (RMST) assessed the 24- and 36-month OS using stabilized inverse probability of treatment weighting of propensity scores. We included 356 patients (median age: 81 years), and 164 (46%) received a GDT (95% confidence interval (CI) = (41-51%)). Patients with metastases were less likely to receive a GDT (adjusted odds ratio (95% CI) = 0.34 (0.17-0.69); p = 0.003). After weighting, the RMST at 24 months was shorter in the GDT group (13.9 months, vs. 17 months for compliant treatments; difference (95% CI): -3.1 months (-5.3, -1.0); p = 0.004). RMST at 36 months was 18.5 months, vs. 21.8 months (difference: -3.3 months (-6.7, 0.0); p = 0.053). GDT is common in older patients with prostate cancer and especially those with non-metastatic disease. GDT was associated with worse survival, independently of health status and tumour characteristics.

Changes in prostate cancer screening practice by blood PSA testing between 2011 and 2017, a French population-based study

OBJECTIVE

The aim of the study was to determine the trend of first blood prostate-specific antigen (PSA) test prescription in France between 2011 and 2017, based on the assumption that prostate cancer (PCa) screening is expected to decline over the years.

METHOD

Using a representative sample of the French population from the French Health Insurance database, we identified 50-52-year-old men without PCa and without any blood PSA test in the five years before 2011, 2014 and 2017 (January 1-December 31 of each year). For each of these three years, the primary outcome was the first reimbursement of a blood PSA test. We used a logistic regression model with first blood PSA test as the outcome and year as the main explanatory variable. As secondary objectives, we also identified the prescriber's specialty, the urological consultation frequency, and the number of prostate biopsies in the year after the first blood PSA test reimbursement (only for 2011 and 2014).

RESULTS

In 2011, 2014 and 2017, 5 275, 5 792 and 5 887 50-52-year-old men, respectively, were included. The percentage of patients with a first blood PSA test prescription decreased linearly from 2011 to 2017: 15.7% in 2011, 13.2% in 2014, and 12.4% in 2017 (p < .001). Blood PSA testing was mainly prescribed by general practitioners (>95%). The median interval between PSA tests was 13 months in 2011 and 14 months in 2014. Fewer than 10% of men had ≥1 consultation with an urologist during the year after the first blood PSA test. After the first blood PSA test, eight prostate biopsies were performed in 2011 and two in 2014.

CONCLUSION

Our results suggest that in France, PCa screening is a primary care issue. Although PCa screening remains controversial and confusion exists about the best practice, our study showed a linear decrease of blood PSA test prescriptions for 50-52-year-old men between 2011 and 2017, although the reason for screening was unknown. As clinical information was not available, additional evidence is needed to determine the real impact of this decrease on the cancer-specific and overall mortality.

Outcomes of oesophageal cancer treated with neoadjuvant compared with definitive chemoradiotherapy

Introduction: We report outcomes of patients with oesophageal cancer treated with neoadjuvant chemoradiotherapy (NACRT) plus surgery or definitive chemoradiotherapy (chemoRT) at our institution. Methods: We retrospectively reviewed patients who underwent chemoRT from 2005 to 2017. The primary outcome was overall survival (OS). Secondary outcomes were disease-free survival (DFS) and toxicities. Results: We identified 96 patients with median age of 64 years and squamous cell carcinoma in 82.3%. Twenty-nine patients (30.2%) received NACRT plus surgery, 67 patients (69.8%) received definitive chemoRT. Median follow-up was 13.5 months. The 3/5-year OS were 26.4%/13.4%, and 59.6%/51.6% in the definitive chemoRT and NACRT plus surgery groups, respectively. The 3/5-year DFS were 19.3%/12.3%, and 55.7%/37.2% in the definitive chemoRT and NACRT plus surgery groups, respectively. NACRT plus surgery significantly improved OS (hazard ratio [HR] 0.40, 95% confidence interval [CI] 0.22–0.72, P<0.01) and DFS (subhazard ratio [SHR] 5.21, 95 CI 1.20–22.7, P=0.03). Multivariable analysis for OS in the definitive chemoRT group indicated stage (1–2 vs 3–4a; HR 2.17, 95% CI 1.15–4.11, P=0.02) and feeding tube (no tube versus tube; HR 1.85, 95% CI 1.00–3.43, P=0.05) as significantly associated with OS. The cumulative incidence of local recurrence was significantly higher in the definitive chemoRT group (SHR 5.21, 95 CI 1.2022.7, P=0.03). Nineteen patients (65.5%) had postoperative complications. Conclusion: NACRT plus surgery improved OS and DFS. However, in view of treatment-related complications, careful selection of patients is warranted. With the predominant histology of our cohort being squamous cell carcinoma (SCC), our results may be more re levant for those with SCC.

Comparison of G8 and ISAR Screening Results in Geriatric Urology

Background: The G8 and ISAR scores are two different screening tools for geriatric risk factors and frailty. The aim of this study was to compare the G8 and ISAR screening results in a cohort of urogeriatric patients to help clinicians to better understand and choose between the two tests. Methods: We retrospectively evaluated 100 patients at the age of 75 and above who were treated for different urological conditions. All routinely and prospectively underwent G8 and ISAR screening tests. A G8 score ≤ 14 and an ISAR score > 2 were considered positive. The results for the two tests were compared and correlated to clinical data. Results: The mean age of the patients was 83 y (min. 75–max. 101); 78 of the patients were male, while 22 were female; 58 of the patients were G8-positive, while 42 were G8-negative; and 24 were ISAR-positive, while 76 ISAR were negative. All the ISAR-positive patients were also G8-positive. There was a significant negative correlation between the G8 and ISAR scores (r = −0.77, p < 0.001). Both tests correlated significantly with the Charlson comorbidity index, length of stay, number of coded diagnosis, and Braden score (p < 0.05). Conclusion: Both tests are significantly correlated with each other and to clinical data related to geriatric frailty. However, the G8 score has a much higher rate of positive tests, which limits its use in daily routine, and the ISAR score is therefore preferable. For “fit” geriatric patients, however, a negative G8 score can be of great use as a confirmatory test for further decision making.

Safety and survival of docetaxel and cabazitaxel in metastatic castration-resistant prostate cancer

OBJECTIVES

To investigate real-world haematological toxicity, overall survival (OS) and the treatment characteristics of docetaxel and cabazitaxel chemotherapy in metastatic castration-resistant prostate cancer (mCRPC).

PATIENTS AND METHODS

This retrospective claims data study followed patients with mCRPC receiving cabazitaxel or docetaxel from their first chemotherapy infusion. Haematological toxicities were measured using treatment codes and inpatient diagnoses. OS was estimated using the Kaplan-Meier method. A multivariable Cox regression analysis was used to identify OS predictors.

RESULTS

Data from 539 patients administered docetaxel and 240 administered cabazitaxel were analysed. Regarding adverse events, within 8 months of treatment initiation, some kind of treatment for haematological toxicity was documented in 31% of patients given docetaxel and in 61% of patients given cabazitaxel. In the same period, hospitalization associated with haematological toxicity was documented in 11% of the patients in the docetaxel cohort and in 15% of the patients in the cabazitaxel cohort. In the docetaxel cohort, 9.9% of patients required reverse isolation and 13% were diagnosed with sepsis during hospitalization. In the cabazitaxel cohort, the cumulative incidence was 7.9% and 15%, respectively. The median OS was reached at 21.9 months in the docetaxel cohort and, because of a later line of therapy, at 11.3 months in the cabazitaxel cohort. A multivariate Cox regression revealed that indicators of locally advanced and metastatic disease, severe comorbidities, and prior hormonal/cytotoxic therapies were independent predictors of early death.

CONCLUSION

Cabazitaxel patients face an increased risk of haematological toxicities during treatment. Together with their short survival time, this calls for a strict indication when using cabazitaxel in patients with mCRPC.

Obesity and low levels of physical activity impact on cardiopulmonary fitness in older men after treatment for prostate cancer

The purpose of this study was to compare fitness parameters and cardiovascular disease risk of older and younger men with prostate cancer (PCa) and explore how men's fitness scores compared to normative age values. 83 men were recruited post-treatment and undertook a cardiopulmonary exercise test (CPET), sit-to-stand, step-and-grip strength tests and provided blood samples for serum lipids and HbA1c. We calculated waist-to-hip ratio, cardiovascular risk (QRISK2), Charlson comorbidity index (CCI) and Godin leisure-time exercise questionnaire [GLTEQ]. Age-group comparisons were made using normative data. Men > 75 years, had lower cardiopulmonary fitness, as measured by VO₂ Peak (ml/kg/min) 15.8 + 3.8 p < 0.001, and lower grip strength(28.6+5.2 kg p < 0.001) than younger men. BMI ≥30kg/m² and higher blood pressure all contributed to a QRisk2 score indicative of 20% chance of cardiovascular risk within 10 years (mean: 36.9-6.1) p < 0.001. Age, BMI and perceived physical activity were significantly associated with lower cardiopulmonary fitness. Men with PCa > 75 years had more cardiovascular risk factors compared to normative standards for men of their age. Although ADT was more frequent in older men, this was not found to be associated with cardiopulmonary fitness, but obesity and low levels of physical activity were. Secondary prevention should be addressed in men with PCa to improve men's overall health.

Does the type of cryoprobe affect oncological and functional outcomes in men with clinically localized prostate cancer treated with primary whole gland prostate cryoablation?

Background

This study aimed to compare the oncological and functional outcomes of primary whole gland cryoablation of the prostate using the variable ice cryoprobe (V-Probe^®) and the conventional fixed-size ice probe.

Materials and methods

We reviewed the Cryo On-Line Data Registry for men who were treated with primary whole gland prostate cryoablation from 2000 through 2017. A multivariate Cox proportional hazards model was used to compare timing to biochemical recurrence between the V-Probe^® and fixed-size ice probe after adjusting for preoperative prostate-specific antigen (PSA), neoadjuvant androgen deprivation therapy, preoperative Gleason score, and preoperative T stage.

Results

A total of 1124 men were included. Median age, Gleason score, and pretreatment PSA were 70 years (interquartile range [IQR]: 65-74 years), 7 (IQR: 6-7) and 5.9 ng/mL (IQR: 4.6-8.1 ng/mL), respectively. The median follow-up time was 25.0 months (IQR: 11.2-48.6 months). V-Probes^® were used in 269 (23.9%) cases and fixed-size ice probes in 858 (76.1%) cases. After adjusting for clinical T stage, PSA, neoadjuvant androgen deprivation therapy and preoperative Gleason score, on the multivariate Cox regression model, we found that there was no significant difference between the type of probe and timing to biochemical recurrence (p = 0.35). On multivariate logistic regression, using the V-Probe^® was associated with a 91% increase in postoperative urinary retention compared to the fixed-size ice probe (p = 0.003).

Conclusions

The use of the V-Probe^® versus conventional fixed-size ice probe was not associated with a difference in biochemical recurrence in patients undergoing primary cryoablation of the prostate.

2020 Korean guidelines for the management of metastatic prostate cancer

In 2017, Korean Society of Medical Oncology (KSMO) published the Korean management guideline of metastatic prostate cancer. This paper is the 2nd edition of the Korean management guideline of metastatic prostate cancer. We updated recent many changes of management in metastatic prostate cancer in this 2nd edition guideline. The present guideline consists of the three categories: management of metastatic hormone sensitive prostate cancer; management of metastatic castration resistant prostate cancer; and clinical consideration for treating patients with metastatic prostate cancer. In category 1 and 2, levels of evidence (LEs) have been mentioned according to the general principles of evidence-based medicine. And grades of recommendation (GR) was taken into account the quality of evidence, the balance between desirable and undesirable effects, the values and preferences, and the use of resources and GR were divided into strong recommendations (SR) and weak recommendations (WR). A total of 16 key questions are selected. And we proposed recommendations and described key evidence for each recommendation. The treatment landscape of metastatic prostate cancer is changing very rapid and many trials are ongoing. To verify the results of the future trials is necessary and should be applied to the treatment for metastatic prostate cancer patients in the clinical practice. Especially, many prostate cancer patients are old age, have multiple underlying medical comorbidities, clinicians should be aware of the significance of medical management as well as clinical efficacy of systemic treatment.

Comprehensive geriatric assessment in older adults with cancer: Recommendations by the Italian Society of Geriatrics and Gerontology (SIGG)

INTRODUCTION

Optimizing the approach to older adults with cancer is now a priority given the increasing frequency of new cancer diagnoses that are made in the older population. The comprehensive geriatric assessment (CGA) represents the gold-standard for (1) defining prognosis and ability to withstand cancer treatments, (2) exploring the multiple aspects that define the complexity of frail older persons, and (3) designing person-tailored interventions.

MATERIALS AND METHODS

In this document, based on a comprehensive revision of the literature, the Italian Society for Geriatrics and Gerontology proposes a CGA model (ONCOGER CGA) to be adopted by oncology centers for their routine approach to older patients with cancer.

RESULTS AND DISCUSSION

A widespread use of this standardized CGA format will facilitate comparisons across institutions, promote studies based on a multidimensional patient assessment, and foster the inclusion of geriatric endpoints in oncological clinical trials. Furthermore, we predict that the use of a standardized CGA approach will increase the integration of geriatricians into oncology care teams with the final result of improving therapeutic choices and clinical outcomes.

A novel screening strategy for clinically significant prostate cancer in elderly men over 75 years of age

A standard modality for prostate cancer detection in men 75 years and older has not been established. A simple screening method for elderly patients is needed to avoid unnecessary biopsies and to effectively diagnose prostate cancer. A retrospective study was conducted on elderly patients who had prostate biopsy at Kanazawa University Hospital (Kanazawa, Japan) between 2000 and 2017. Of the 2251 patients who underwent prostate biopsy, 254 had clinically significant prostate cancer (CSPC) with a Gleason score (GS) of≥7 and 273 had a GS of <7 or no malignancy. In this study, patients aged 75 years or older were classified as elderly patients. GS ≥ 7 was characterized by a prostate-specific antigen (PSA) of the maximum area under the curve of 12 ng ml^-1 with a sensitivity of 76.2% and a specificity of 73.2%. For PSA levels between 4 ng ml^-1 and 12 ng ml^-1, based on the maximum area under the curve, patients with three or four of the following factors may present a GS of ≥ 7: percent free PSA >24, PSA density≥ 0.24 ng ml^-2, positive findings on digital rectal examination, and transrectal with 90.0% sensitivity and 67.4% specificity. In this study, we found that raising the PSA cutoff to 12 ng ml^-1 for CSPC in elderly individuals can significantly reduce unnecessary prostate biopsies. Furthermore, CSPC could be efficiently discovered by combining the four supplementary markers in patients with a PSA level of 4-12 ng ml^-1. By performing this screening for elderly men over 75 years of age, unnecessary biopsies may be reduced and CSPC may be detected efficiently.

Impact of Androgen Deprivation Therapy Associated to Conformal Radiotherapy in the Treatment of D'Amico Intermediate-/High-Risk Prostate Cancer in Older Patients

PURPOSE/OBJECTIVE

The association of 3D Conformal External Beam Radiotherapy (3D-CEBRT) with adjuvant Androgen Deprivation Therapy (ADT) proved to treat patients with intermediate- and high-risk localized prostate cancer (IR and HR). However, older patients were underrepresented in literature. We aimed to report the oncological results and morbidity 3D-CEBRT +ADT in ≥80 years patients.

MATERIAL AND METHODS

From June 1998 to July 2017, 101 patients ≥80 years were included in a tertiary center. The median age was 82 years. ADT was initiated 3 months prior 3D-CEBRT in all patients, with a total duration of 6 months for IR prostate cancer (group A; n = 41) and 15 months for HR prostate cancer (group B; n = 60). Endpoints included overall survival (OS), metastasis-free survival (DMFS), biochemical recurrence-free survival (BRFS) and toxicity.

RESULTS

Five years-OS was 95% and 86.7% in groups A and B, respectively. Cardiovascular events occurred in 22.8% of ≥80 years patients with no impact on OS. In the multivariate analysis, age <82 years, Karnofsky index and normalization of testosterone levels were significantly associated with better OS.

CONCLUSION

Age ≥80 years should not be a limitation for the treatment of IR and HR prostate cancer patients with 3D-CEBRT and ADT, but cardiovascular monitoring and prevention are mandatory.

Frailty screening by Geriatric-8 and 4-meter gait speed test is feasible and predicts postoperative complications in elderly colorectal cancer patients

INTRODUCTION

Identification of frail older colorectal cancer patients might help to select those prone to adverse events and may lead to adjustment of treatment plans. However, the prognostic validity of screening for frailty is unknown.

METHODS

This retrospective study evaluates colorectal cancer patients ≥70 years who underwent elective surgery between May 2016 and December 2018. The Geriatric-8 (G8) and 4-m gait speed test (4MGST) were used as frailty screening tools. According to hospital guidelines, patients were referred to a geriatrician when screening was indicative for frailty (G8 ≤ 14 and/or 4MGST < 1 m/s). Patients were categorized as fit, vulnerable or frail by comprehensive geriatric assessment (CGA). The clinical implications and prognostic validity of frailty screening and CGA were evaluated.

RESULTS

149 patients were included, of whom 132 (89%) were screened for frailty. Frailty was suspected in 40% of screened patients (n = 53) of whom 89% (n = 47) was referred for CGA. A higher complication rate was seen in patients with G8 ≤ 14 and/or 4MGST < 1 m/s compared to those with G8 > 14 and 4MGST ≥1 m/s (respectively 62% versus 28%,p < 0.001). Pneumonia (21% versus 6%, p = 0.013) and cardiac complications (11% versus 4%, p = 0.093) were more prevalent in patients with G8 ≤ 14 and/or 4MGST < 1 m/s. CGA identified frail patients as a group with a high complication rate of 68%.

CONCLUSION

Screening for frailty with subsequent referral for CGA is feasible in older colorectal cancer patients. Our study suggests that screening for frailty by G8 + 4MGST can identify patients with higher risk for postoperative complications.

Undertreatment and overtreatment in older patients treated with chemotherapy

BACKGROUND

Inconsistent doses and schemes are commonly used in older patients receiving cancer chemotherapy. We performed this study in patients with cancer and age ≥ 70 years to determine the frequency of undertreatment and overtreatment as well as factors influencing the decision to modify chemotherapy doses.

PATIENTS AND METHODS

Patients aged ≥70 years starting new chemotherapy regimens were prospectively included in a multicentre study. The schedule and drug doses were determined by the treating oncologist. Pre-chemotherapy assessment included sociodemographics, treatment details and geriatric assessment (GA) variables. Association between these factors and undertreatment (use of less intensive cancer treatment [LICT] in a fit patient) or overtreatment (use of standard cancer treatment in an unfit older patient) were examined by multivariate logistic regression.

RESULTS

Three- hundred ninety-seven patients were included, 43% of whom received LICT. If not adjusted for GA, toxicity did not differ between those receiving LICT (38%) or standard doses of chemotherapy (37%). If the dose of chemotherapy was analyzed according to the results of GA 61 (15%) patients had been undertreated and 133 (34%) had been overtreated. Undertreatment was related with increasing age and decreased renal function. Factors related with overtreatment were younger age, curative intention of treatment, prescription of G-CSF as primary prophylaxis and adequate cognitive status. Overtreated patients had more grade 3-4 toxicity than those receiving treatment adapted to fragility (42% vs 31%; p < 0.05).

CONCLUSIONS

The use of chemotherapy without considering GA leads to overtreatment more commonly than undertreatment in older patients with cancer. Oncologists should take into account the results of GA to stratify patients and to avoid under or overtreatment.

Frailty and diabetes status in older patients with cancer: impact on mortality in the ANCRAGE cohort

BACKGROUND

Frailty, diabetes and cancer are associated with aging, but the relationship between these conditions is not well defined.

AIMS

We studied older patients with cancer from the prospective single-center cohort ANCRAGE (ANalyses of CanceR in AGEd) aiming to determine the impact of type 2 diabetes (T2D) and its vascular complications (VC) on frailty and adverse outcomes (mortality, unplanned readmission) during follow-up.

METHODS

Analysis of cohort patients ≥ 75 years, included between 2009 and 2017, who underwent a comprehensive geriatric assessment (CGA). Variables of interest were history of T2D and VC, tumor site and metastatic status, CGA including eight domains (social environment, functional status, mobility, nutrition, mood, cognition, polypharmacy and comorbidities) and frailty.

RESULTS

Among 1092 patients (47% female, mean age 82 ± 5 years), 219 (20%) had a reported diagnosis of T2D at baseline including 152 (69%) with VC. The most common tumor sites were prostate (15%), breast (15%), skin (12%), and colorectum (11%); 29% of patients had a metastatic disease. Frailty was highly prevalent (84%). During follow-up (median of 15.3 months), 653 (60%) patients died (60% no T2D, 43% T2D without VC, 66% with VC). After adjustment for age, gender and metastatic status, diabetics with VC had a higher risk of all-cause death (aHR1.89, 1.24-2.86, p = 0.004). Death was more frequently due to a non-cancer cause (p < 0.001). No difference in unplanned readmissions was observed in the three groups. Frailty was an independent risk factor for mortality and unplanned readmissions (p < 0.001 both).

CONCLUSION

In older cancer patients from the prospective ANCRAGE cohort, all-cause mortality was significantly higher in frail patients and those with complicated T2D, a finding questioning the quality of care management in such vulnerable patients, and stimulating further research in this multidisciplinary field.

Histopathology, pharmacotherapy, and predictors of prostatic malignancy in elderly male patients with raised prostate-specific antigen levels - A prospective study

Background

Prostate cancer is the second most common cancer among adult men in the world, and the diagnosis requires biopsy. Prostate-specific antigen (PSA) test along with digital rectal examination (DRE) increases the detection rate of prostate cancer than DRE alone. The objective of this study was to correlate serum PSA level with histopathological diagnosis, identify the predictors of malignancy, and describe the pharmacotherapy of patients with serum PSA levels >4 ng/ml.

Materials and Methods

This was a hospital-based observational study done among patients who presented with lower urinary tract symptoms and PSA levels >4 ng/ml who were planned to undergo prostatic biopsy. DRE followed by transrectal ultrasound (TRUS) assessment and guided sextant (6-core) prostatic biopsy was performed.

Results

One hundred and four patients were screened and 87 were included. Nineteen patients were diagnosed with malignancy, and among them, eight had bone metastasis. Spearman's correlation coefficient between PSA and malignancy was 0.449 (P ≤ 0.001). Multivariate analysis suggested that the factors (adjusted odds ratio; 95% confidence interval; P value) such as increasing age (1.127; 1.013, 1.253; 0.027), nodular prostate (22.668; 4.655, 110.377; P < 0.001), and PSA (1.034; 1.004, 1.064; 0.024) were significant predictors of prostate cancer. All patients with benign prostatic hyperplasia were advised a combination therapy with 5-alpha reductase inhibitor and selective alpha-1 receptor antagonist while those with malignancy were prescribed androgen deprivation therapy with antiosteoporosis therapy.

Conclusion

In elderly patients with raised PSA levels or suspicious DRE findings, TRUS-guided prostate is recommended to rule out malignancy and plan appropriate management.

Caring for older cancer patients: A scoping review

There is a growing recognition among oncologists that older patients differ from other cancer patients. Older patients present age-specific issues affecting the prevention and management of their cancer. Over the years, this has led to the development of the discipline of geriatric oncology, which is the set of practices elaborated to evaluate, treat, follow-up and rehabilitate the population of older cancer patients. Geriatric oncology is still struggling to establish itself in healthcare settings managing older cancer patients. Efforts are currently being made to make it a recognized medical specialty. Health policy makers have to have a grasp of the evolution of this discipline because it concerns a fast growing segment of the cancer patient population. To shed light on the literature about this field, we undertook a scoping review in which we identified relevant studies; charted the data from the selected studies, collated, summarized and reported the results. From 2043 references initially identified, we included 92 articles in our scoping review and extracted data from 88 articles. The included articles were classified into three major categories, namely Advancing the discipline, Organization of care and Nursing and support services for patient and their caregivers. This review affords researchers and policy makers a foundation to help conduct many other conversations on each theme and sub-theme.

Risk Assessment and Considerations for Proper Management of Elderly Men with Advanced Prostate Cancer: A Systematic Review

CONTEXT

Treatment decisions for elderly men with prostate cancer are complicated by the intersection of competing risks of cancer, potential complications of treatment, and individual patients' comorbidities.

OBJECTIVE

To perform a systematic review of data guiding the assessment of elderly prostate cancer patients that addresses the risk from cancer and treatment, and to discuss a patient-centered approach to incorporating these factors into decision making.

EVIDENCE ACQUISITION

Evidence was gathered via a systematic review of the current literature. The search strategy used the terms prostate cancer, elderly, geriatric, >75 yr of age, risk assessment, and treatment in several combinations, and was limited to phase ≥ II clinical trials published between January 2008 and November 2018. Additional supporting literature for the discussion was pulled by hand search.

EVIDENCE SYNTHESIS

The benefits of treatment identified for systemic therapies commonly used to treat men with prostate in general extend to elderly patients. Evidence supports a multifaceted assessment of the risks of cancer and aging, and an understanding of the side effects of treatment to optimally guide therapeutic decision making for elderly patients. There is little evidence defining a geriatric risk stratification system specific to prostate cancer, and recommendations are predominantly based on adapted geriatric oncology approaches and expert consensus.

CONCLUSIONS

The care of elderly men with prostate cancer should incorporate a review of cancer risk, an assessment of aging, and an understanding of the effects of treatment to provide the patient with thorough and personalized guidance for treatment decisions. Future studies of elderly men with prostate cancer can define and validate ideal risk stratification methods as well as management approaches that may be distinct from those for younger populations.

PATIENT SUMMARY

Treatment decisions for elderly men with prostate cancer require consideration of the risk posed by the cancer coupled with an understanding of the patient's general health status.

Prostate cancer in Pennsylvania: The role of older age at diagnosis, aggressiveness, and environmental risk factors on treatment and mortality using data from the Pennsylvania Cancer Registry

Background

To assess: (a) cancer treatment in prostate cancer survivors (PCS) by age at diagnosis (ADx) and prostate cancer (PC) aggressiveness; (b) potential impact on PC mortality; and (c) these results in the context of environmental/behavioral risk factors on PCS in Pennsylvania.

Methods

Prostate cancer survivors ages ≥40 years were identified from the 2004‐2014 Pennsylvania Cancer Registry (PCR). Demographic/clinical descriptors and PC treatment were extracted from PCR. Prostate cancer aggressiveness was defined by clinical/pathologic Gleason score and tumor stage. Logistic and Cox regression analyses tested associations between treatment received and PC‐specific mortality. County‐level data from the Pennsylvania BRFSS were used to estimate cancer‐related behavioral risk factors (eg, smoking, physical inactivity, fruit/vegetable consumption [FV], alcohol use) and used as covariates.

Results

There were 90 694 PCS ages 40‐105 years (mean age = 66.19 years, SD = 9.25) included. Most were non‐Hispanic white men (83%). Prostate cancer survivors ≥75 years were least likely to receive any treatment but men ages 65‐74 were more likely to receive combined therapies (OR = 1.47; 95% CI 1.28, 1.69) vs PCS ages 40‐54 years, controlling for covariates. Prostate cancer survivors 55‐75+ with aggressive PC who received any treatment vs no definitive treatment had significantly reduced mortality. Men from counties with high obesity and smoking rates were significantly less likely to receive any treatment than men living in counties with lower rates of these risk factors. Prostate cancer survivors who lived in counties with high rates of physical inactivity and had high rates of sufficient FV consumption were slightly more likely to receive cancer treatment vs no definitive treatment compared to men who lived in counties with high rates of physical activity and lower FV consumption.

Conclusions

We observed a general age‐related decline in receipt of treatment. Prostate cancer survivors ages ≥75 years were significantly less likely to get any cancer treatment compared to younger PCS. However, most men with more aggressive disease who received any treatment had greatly reduced PC mortality, regardless of age. Considering environmental/behavioral risk factors may attenuate PC risk and inform treatment options.

Cabazitaxel in patients aged ≥80 years with castration-resistant prostate cancer: Results of a post-marketing surveillance study in Japan

OBJECTIVES

Data on the safety and efficacy of cabazitaxel in patients aged ≥80 years with castration-resistant prostate cancer (CRPC) are limited. We report the safety (adverse drug reactions [ADRs]) and efficacy (overall survival [OS], time to treatment failure [TTF], and prostate-specific antigen [PSA] response rates) in patients aged <80 or ≥80 years treated with cabazitaxel for CRPC in clinical practice.

MATERIALS AND METHODS

We performed post-hoc subgroup analyses of a Japanese post-marketing surveillance study involving 662 patients with CRPC treated with cabazitaxel between September 2014 and June 2016.

RESULTS

In patients aged <80 (n = 610) and ≥80 years (n = 49), median PSA at baseline was 168.7 and 109.0 ng/mL, and 86.7% and 83.7% of patients were previously treated with enzalutamide and/or abiraterone. ADRs (all grade) occurred in 77.2% and 79.6% of patients aged <80 and ≥80 years, with grade three/worse ADRs in 61.8% and 63.3% of patients. Hematologic toxicities were the most common grade three/worse ADRs, including neutropenia, febrile neutropenia, and anemia in both subgroups. No specific ADRs were observed in patients aged ≥80 years. The PSA response and median OS and TTF were 28.3%, 292 days, and 116 days in patients aged ≥80 years, and 29.7%, 319 days, and 125 days in patients aged <80 years.

CONCLUSION

Cabazitaxel could be a treatment option for CRPC in patients aged ≥80 years based on its safety and efficacy profiles. This is the first report to investigate the safety and efficacy of cabazitaxel in patients aged ≥80 years with CRPC.

Clinical-genomic Characterization Unveils More Aggressive Disease Features in Elderly Prostate Cancer Patients with Low-grade Disease

BACKGROUND

Over 20% of men diagnosed with prostate cancer (PC) are ≥75 yr old. More objective disease-specific indices for predicting outcomes beyond chronological age are necessary.

OBJECTIVE

To analyze age-related differences in clinical-genomic prognostic features of aggressiveness in localized PC.

DESIGN, SETTING, AND PARTICIPANTS

A retrospective multicenter cross-sectional study reported the use of the Reporting Recommendations for Tumor Marker Prognostic Studies (REMARK) guidelines. Clinical-genomic data of patients who underwent a prostate biopsy or radical prostatectomy (RP) were obtained from the Decipher Genomic Resource Information Database (NCT02609269).

INTERVENTION

Our analyses focused on the 22-gene Decipher genomic classifier (GC) and 50-gene (PAM50) models in the biopsy and RP cohorts stratified by age.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

The primary endpoint was the impact of age on GC scores and PAM50 molecular subtypes. Prognostic indices including Decipher GC scores, PAM50 molecular subtypes, National Comprehensive Cancer Network risk categories, and ISUP grade groups (IGGs) were stratified by age using multivariable logistic regression analyses.

RESULTS AND LIMITATIONS

Within histological low-risk IGGs, there were a higher proportion of patients with high-risk Decipher biopsy scores with age (age <60 yr: 10.1% IGG 1 and 29.9% IGG 2 vs age ≥80 yr: 22% IGG 1 and 37.7% IGG 2). The prevalence of the adverse phenotype luminal B (PAM50-defined) increased with age (age <60 yr: 22.7% and 40.2% vs age ≥80 yr: 29.7% and 49.1%, in patients with IGG 1 and IGG 2, respectively). In IGGs 3-5, no age differences were observed. Multivariable models demonstrated that each age decile entailed a 19% (odds ratio [OR] 1.19, 95% confidence interval [CI] 1.10-1.29, p < 0.001) and a 10% (OR 1.1, 95% CI 1.05-1.16) increased probability for a high-risk Decipher biopsy and RP score, respectively. Aside from an obvious selection bias, data on race, family history, prostate volume, and long-term follow-up outcomes were unavailable.

CONCLUSIONS

These data demonstrated that elderly men with favorable pathology (IGG 1-2), might harbor more aggressive disease than younger patients based on validated GC scores.

PATIENT SUMMARY

The presented clinical-genomic data demonstrate that elderly patients with low-risk prostate cancer might harbor more aggressive disease than their younger counterparts. This suggests that standard well-accepted paradigm of elderly prostate cancer patients not being aggressively treated, based solely on their chronological age, might need to be reconsidered.

[Cross-speciality geriatrics: A health-care challenge for the 21st century]

Increasing numbers of older persons are being treated by specialties other than Geriatric Medicine. Specialists turn to Geriatric Teams when they need to accurately stratify their patients' risk and prognosis, predict the potential impact of their, often, invasive interventions, optimise their clinical status, and contribute to discharge planning. Oncology and Haematology, Cardiology, General Surgery, and other surgical departments are examples where such collaborative working is already established, to a varying extent. The use of the term "Cross-speciality Geriatrics" is suggested when geriatric care is provided in clinical areas traditionally outside the reach of Geriatric Teams. The core principles of Geriatric Medicine (comprehensive geriatric assessment, patient-centred multidisciplinary targeted interventions, and input at point-of-care) are adapted to the specifics of each specialty and applied to frail older patients in order to deliver a holistic assessment/treatment, better patient/carer experience, and improved clinical outcomes. Using Comprehensive Geriatric Assessment methodology and Frailty scoring in such patients provides invaluable prognostic information, helps in decision making, and enables personalised treatment strategies. There is evidence that such an approach improves the efficiency of health care systems and patient outcomes. This article includes a review of these concepts, describes existing models of care, presents the most commonly used clinical tools, and offers examples of excellence in this new era of geriatric care. In an ever ageing population it is likely that teams will be asked to provide Cross-specialty Geriatrics across different Health Care systems. The fundamentals for its implementation are in place, but further evidence is required to guide future development and consolidation, making it one of the most important challenges for Geriatrics in the coming years.

Impact of age at diagnosis of de novo metastatic prostate cancer on survival

BACKGROUND

An older age at the diagnosis of prostate cancer has been linked to worse prostate cancer-specific survival (PCSS). However, these studies were conducted before the approval of many life-prolonging drugs. This study was aimed at describing outcomes in a contemporary cohort of men diagnosed with de novo metastatic prostate cancer (mPCa) and assessing associations with the age at diagnosis while controlling for known prognostic factors.

METHODS

The Surveillance, Epidemiology, and End Results registry was used to identify men diagnosed with mPCa from 2004 to 2014. Men were classified by 4 age groups: ≤54, 55 to 64, 65 to 74, and ≥75 years. The median overall survival, PCSS, and restricted mean survival times for any-cause mortality and prostate cancer-specific mortality (PCSM) were calculated. Multivariable and subdistribution hazard ratios for PCSM according to age group and with controlling for race, marital status, and income were estimated.

RESULTS

Compared with men aged ≤54 years, men aged ≥75 years experienced a mean PCSS at 5 years that was 6.7 months shorter (95% confidence interval [CI], 5.5-7.8 months). In multivariable analyses, men aged ≥75 years had a 49% increase in the rate of PCSM in comparison with those aged ≤54 years (95% CI, 1.39-1.60). The subdistribution hazard ratio for PCSM between these groups was 1.41 (95% CI, 1.32-1.50).

CONCLUSIONS

Age was found to be an independent predictor of shorter PCSS in men diagnosed with de novo mPCa even in an era with more effective therapies. Further work is needed to determine the reason for poor outcomes in older men with mPCa.

Is age an independent risk factor for perioperative mortality and morbidity after radical prostatectomy? Analysis of the American college of surgeons national surgical quality improvement program database

Objectives

To assess the safety and surgical outcomes of radical prostatectomy (RP) when looking at age as an independent risk factor of perioperative mortality and morbidity.

Patients and methods

A retrospective cohort study was performed using American College of Surgeons National Surgical Quality Improvement Program database. Patients who underwent a RP from 2008 to 2015 were identified. They were divided into three groups based on their age 15 group at the time of surgery. Patients’ characteristics were compared across the three following age groups: 74 years. The correlation between the three different age groups and their respective 30-day postoperative mortality and morbidity were assessed using logistic regression. Unadjusted and adjusted odds ratios (ORs) were estimated.

Results

A total of 43025 patients were identified, 81.7% were aged 74 years. Overall, 102 patients died in the 30-day postoperative period. Univariate and multivariate analysis showed a significant increase in the 30-day postoperative mortality from 0.1% to 0.4% to 1.3% in the three different age groups 74 years, respectively. In addition, there was a significant increase in postoperative complications in the group of patients aged >74 years. A higher risk of complications 25 related to cardiac (OR 2.18 in age group 70–74 vs OR 7.45 in age group >74 years), respiratory (OR 2.36 vs OR 5.91), neurological (OR 2.28 vs OR 3.44), wound infections (OR 1.49 vs OR 3.25), and sepsis (OR 1.54 vs OR 2.64) were seen with the youngest group taken as a reference.

Conclusion

Age is an independent risk factor for perioperative mortality and morbidity after RP in elderly patients. Therefore, age should be considered in the decision making of therapeutic options for patients with prostate cancer.

Prognostic factors for overall survival in prostate cancer patients with different site-specific visceral metastases: A study of 1358 patients

BACKGROUND

Distant metastasis, particularly visceral metastasis (VM), represents an important negative prognostic factor for prostate cancer (PCa) patients. However, due to the lower rate of occurrence of VM, studies on these patients are relatively rare. Consequently, studies focusing on prognostic factors associated with PCa patients with VM are highly desirable.

AIM

To investigate the prognostic factors for overall survival (OS) in PCa patients with lung, brain, and liver metastases, respectively, and evaluate the impact of site-specific and number-specific VM on OS.

METHODS

Data on PCa patients with VM were extracted from the Surveillance, Epidemiology, and End Results database between 2010 and 2015. Univariate and multivariate Cox regression analyses were used to analyze the association between clinicopathological characteristics and survival of patients with different site-specific VM. Kaplan-Meier analyses and Log-rank tests were performed to analyze the differences among the groups.

RESULTS

A total of 1358 PCa patients with site-specific VM were identified from 2010 to 2015. Older age (> 70 years) (P < 0.001), higher stage (T3/T4) (P = 0.004), and higher Gleason score (> 8) (P < 0.001) were found to be significant independent prognostic factors associated with poor OS in PCa patients with lung metastases. Higher stage (T3/T4) (P = 0.047) was noted to be the only independent risk factor affecting OS in PCa patients with brain metastases. Older age (> 70 years) (P = 0.010) and higher Gleason score (> 8) (P = 0.001) were associated with shorter OS in PCa patients with liver metastases. PCa patients with isolated lung metastases exhibited significantly better survival outcomes compared with PCa patients with other single sites of VM (P < 0.001). PCa patients with a single site of VM exhibited a superior OS compared with PCa patients with multiple sites of VM (P < 0.001).

CONCLUSION

This is the first Surveillance, Epidemiology, and End Results-based study to determine prognostic factors affecting OS in PCa patients with different site-specific VM. Clinical assessments of these crucial prognostic factors become necessary before establishing a treatment strategy for these patients with metastatic PCa.

[Geriatric specificities of prostate cancer]

PURPOSE

To describe the epidemiology of prostate cancer (PCa) and its natural history in the elderly patient. To propose adaptations of geriatric evaluation specific to PCa. Recall therapeutic options and the treatment options specific to elderly patients.

METHOD

Bibliographic research from the Medline bibliographic database (NLM Pubmed tool) and Embase, as well as on the websites of scientific societies of geriatrics, from the National Cancer Institute using the following keywords: elderly, geriatrics, prostate cancer, diagnosis, treatment.

RESULTS

The median age at diagnosis for PCa is 69 years old, making PCa the very type of cancer of the elderly. The specific mortality of the disease increases with age. This translates two of its characteristics. First, a diagnosis at higher grade and stage is more common in older patients than in younger patients. Secondly, use of curative therapeutic options is less common in elderly patients than in younger patients. SIOG recommends a specific geriatric assessment for patients with PCa, which may be useful, but the need for an initial detection of cognitive disorders is open to criticism. There is no therapeutic trial, if only prospective, dedicated to elderly patients with PCa. However, decision-making in the elderly patient with PCa must pursue two goals: first, the respect of the expectations specific to each patient and secondly, the search for the global clinical benefit; goals that should not be restricted to elderly patients.

CONCLUSION

PCa in the elderly patient follow the current guidelines for diagnostic and for treatment. Compliance with these guidelines should eliminate both the late diagnosis and the under-treatment actually observed.

[Evaluation of the elderly patient with cancer]

PURPOSE

To explain the notion of frailty, then to explain how crucial is the detection of frailty detection in the elderly patient, and, in cases of suspected frailty, how crucial is the need for geriatric assessment. To describe (i) how this assessment of the elderly cancer patient is performed, (ii) how the results of this geriatric assessment must drive the decision making, and (iii) the role of the geriatrician in the care pathway.

METHOD

Bibliographic research from the Medline bibliographic database (NLM Pubmed tool) and Embase, as well as on the websites of scientific geriatric societies, from the National Cancer Institute using the following keywords: elderly, geriatrics, cancer, frailty, assessment, decision making.

RESULTS

The goal of frailty detection is to optimize care, to maintain the independence and the survival of the patient. The prevalence of frailty increases with the age and the diagnosis of cancer. Detection of frailty in the elderly patient with cancer is performed using the G8 questionnaire recommended by the INCa. In case of anomaly or clinical justification, the patient receives a geriatric assessment, which is a multidimensional and multidisciplinary procedure. The clinician can call on the UCOG of the region in which he practices. The relevance of medical decisions will be based on the results of this geriatric assessment. The geriatrician plays a crucial role and will be involved throughout the care.

CONCLUSION

The detection of frailty in the elderly patient with cancer is obligatory. Consecutive geriatric assessment can be performed by the UCOG of the region. The results of the geriatric assessment must serve as a basis for any therapeutic decision making and the preservation of the independence of the patient must remain the priority.

Interventions to prevent, delay or reverse frailty in older people: a journey towards clinical guidelines

BACKGROUND

Age-related frailty is a multidimensional dynamic condition associated with adverse patient outcomes and high costs for health systems. Several interventions have been proposed to tackle frailty. This correspondence article describes the journey through the development of evidence- and consensus-based guidelines on interventions aimed at preventing, delaying or reversing frailty in the context of the FOCUS (Frailty Management Optimisation through EIP-AHA Commitments and Utilisation of Stakeholders Input) project (664367-FOCUS-HP-PJ-2014). The rationale, framework, processes and content of the guidelines are described.

MAIN TEXT

The guidelines were framed into four questions - one general and three on specific groups of interventions - all including frailty as the primary outcome of interest. Quantitative and qualitative studies and reviews conducted in the context of the FOCUS project represented the evidence base. We followed the GRADE Evidence-to-Decision frameworks based on assessment of whether the problem is a priority, the magnitude of the desirable and undesirable effects, the certainty of the evidence, stakeholders' values, the balance between desirable and undesirable effects, the resource use, and other factors like acceptability and feasibility. Experts in the FOCUS consortium acted as panellists in the consensus process. Overall, we eventually recommended interventions intended to affect frailty as well as its course and related outcomes. Specifically, we recommended (1) physical activity programmes or nutritional interventions or a combination of both; (2) interventions based on tailored care and/or geriatric evaluation and management; and (3) interventions based on cognitive training (alone or in combination with exercise and nutritional supplementation). The panel did not support interventions based on hormone treatments or problem-solving therapy. However, all our recommendations were weak (provisional) due to the limited available evidence and based on heterogeneous studies of limited quality. Furthermore, they are conditional to the consideration of participant-, organisational- and contextual/cultural-related facilitators or barriers. There is insufficient evidence in favour of or against other types of interventions.

CONCLUSIONS

We provided guidelines based on quantitative and qualitative evidence, adopting methodological standards, and integrating relevant stakeholders' inputs and perspectives. We identified the need for further studies of a higher methodological quality to explore interventions with the potential to affect frailty.

Geriatric co-management leads to safely performed cytoreductive surgery in older women with advanced stage ovarian cancer treated at a tertiary care cancer center

OBJECTIVE

To assess fitness and outcomes in older women undergoing cytoreductive surgery for advanced ovarian cancer (OC).

METHODS

A prospective study of OC patients referred to Geriatrics Clinic for preoperative evaluation. All completed the electronic Rapid Fitness Assessment (eRFA) and were followed by Geriatrics Service during inpatient postoperative course, co-managed by Surgical Service. Outcomes were 30-day Intensive Care Unit (ICU) admission, emergency room (ER) visit, readmission, mortality, adverse surgical events. Descriptive statistics were used.

RESULTS

Forty-two women (median age 79, range 74-88), 38 with newly diagnosed advanced OC, 4 with recurrent OC, underwent cytoreductive surgery between 5/2015 and 1/2018. Preoperative age-related impairments per eRFA: high level of distress (71%), functional dependency (59%), limited social activity (59%), depression (57%), slow Time Up and Go (54%), Karnofsky Performance Score (KPS) ≤ 80 (41%), poor social support (43%), polypharmacy (35%), weight loss>10 lbs. (25%), fall history (244%), cognitive impairment (13%). Median number of comorbid conditions = 3. Among 38 newly diagnosed women, 26 (68%) had stage IIIC, 11 (29%) stage IV. Sixteen (42%) underwent primary debulking surgery, 22 (58%) neoadjuvant chemotherapy followed by interval debulking surgery. Median duration of surgery = 245.5 min (range 95-621); median hospital length of stay = 6 days (range 0-22). Optimal debulking rate = 97%, complete gross resection rate = 63%. One patient was admitted to ICU, 26% had 30-day ER visit, 10% were readmitted. Any complication, minor complication, major complication occurred in 58%, 55%, 8%, respectively. Median time from surgery to postoperative chemotherapy = 34.5 days (range 19-66). Median follow-up = 15.7 months (range 3.7-38.0), 12-month survival = 93.3%. There was no 180-day mortality.

CONCLUSION

Cytoreductive surgery among older women with advanced OC and frailty can be performed safely in a tertiary care center with preoperative/postoperative geriatric and surgical co-management.

A retrospective feasibility study of biweekly docetaxel in patients with high-risk metastatic castration-naïve prostate cancer

Background

Results from randomized phase III trials have shown that thrice-weekly docetaxel added to androgen-deprivation therapy (ADT) has a significant impact on the survival of patients with metastatic castration-naïve prostate cancer (mCNPC) and established early chemotherapy as part of the standard of care for high-risk disease. Controversy remains, however, because some patients experience critical toxicities related to docetaxel. The purpose of the current study was to evaluate the feasibility and adverse events of biweekly-administered docetaxel in patients with previously-untreated, high-risk mCNPC.

Methods

The study included 35 consecutive patients with high-risk mCNPC who received ADT plus docetaxel 40 mg/m². Oral prednisone 5 mg twice daily was also given. Treatment was repeated every two weeks for up to 12 cycles or until disease progression or unacceptable toxicity occurred. High-risk was defined as bone metastases beyond axial skeleton and/or visceral disease.

Results

The included patients’ median age was 68 years (range: 31–86 years) and 17 (49%) had visceral metastases. Biweekly docetaxel was generally well-tolerated; the most commonly observed adverse events, considering those of all grades, included alopecia (74%), nail changes (42%), and constipation (31%). Hematologic adverse events were infrequent, and no patient received hematopoietic growth factors. One patient died after the fourth cycle due to respiratory failure, which occurred as a complication of pneumonia. Among the 35 patients, 28 completed the planned 12 cycles of biweekly docetaxel. Prostate-specific antigen response (> 50% decrease from baseline) was recorded in 33 patients (94%), and the radiologic response rate was 49%. Median progression-free survival was 13.6 months (95% confidence interval: 6.7–20.4).

Conclusion

ADT plus biweekly-administered docetaxel appeared to be tolerated and effective in patients with high-risk mCNPC.
