The effect of geriatric intervention in frail older patients receiving chemotherapy for colorectal cancer: a randomised trial (GERICO).

BACKGROUND: Older patients with colorectal cancer (CRC) experience chemotherapy dose reductions or discontinuation. Comprehensive geriatric assessment (CGA) predicts survival and chemotherapy completion in patients with cancer, but the benefit of geriatric interventions remains unexplored. METHODS: The GERICO study is a randomised Phase 3 trial including patients ≥70 years receiving adjuvant or first-line palliative chemotherapy for CRC. Vulnerable patients (G8 questionnaire ≤14 points) were randomised 1:1 to CGA-based interventions or standard care, along with guideline-based chemotherapy. The primary outcome was chemotherapy completion without dose reductions or delays. Secondary outcomes were toxicity, survival and quality of life (QoL). RESULTS: Of 142 patients, 58% received adjuvant and 42% received first-line palliative chemotherapy. Interventions included medication changes (62%), nutritional therapy (51%) and physiotherapy (39%). More interventional patients completed scheduled chemotherapy compared with controls (45% vs. 28%, P = 0.0366). Severe toxicity occurred in 39% of controls and 28% of interventional patients (P = 0.156). QoL improved in interventional patients compared with controls with the decreased burden of illness (P = 0.048) and improved mobility (P = 0.008). CONCLUSION: Geriatric interventions compared with standard care increased the number of older, vulnerable patients with CRC completing adjuvant chemotherapy, and may improve the burden of illness and mobility.

Use of antidepressants in women after prophylactic bilateral oophorectomy: A Danish national cohort study.

OBJECTIVE: To investigate the association between prophylactic bilateral oophorectomy and use of antidepressants in women with a family history of cancer. METHODS: Nationwide population-based cohort study using Danish National Registries including women oophorectomized due to a family history of cancer (n = 2,002) and an age matched reference group (n = 18,018). Analyses were stratified by age at time of bilateral oophorectomy and use of hormone replacement therapy (HRT). RESULTS: Women oophorectomized at age ≤ 45 years were more likely to use antidepressants from the first year after bilateral oophorectomy (OR = 1.34; 95 % CI: 1.08-1.65) compared to the reference group. Women oophorectomized at age 46-55 years and at age >55 years had no significantly increased use of antidepressants (OR = 0.90; 95 % CI: 0.68-1.18 and OR = 1.14; 95 % CI: 0.81-1.61). The increased use of antidepressants in women oophorectomized at age ≤ 45 years was limited to women treated with HRT (OR = 1.51; 95 % CI: 1.18-1.94) whereas women oophorectomized at age ≤ 45 years not treated with HRT had no increased use of antidepressants (OR = 1.03; 95 % CI: 0.70-1.51). CONCLUSIONS: Women oophorectomized due to a family history of cancer at age ≤ 45 years were more likely to use antidepressants after bilateral oophorectomy. The increased use of antidepressants was limited to women treated with HRT. The study calls for further large-scale studies to understand how bilateral oophorectomy and concomitant HRT affects risk of depression in women with a family history of cancer.

Randomised phase II trial of stereotactic body radiotherapy in combination with checkpoint inhibitors in metastatic castration-resistant prostate cancer (CheckPRO): a study protocol.

INTRODUCTION: Immunotherapy with checkpoint inhibitors (CPIs) has revolutionised cancer treatment but has no convincing effect in metastatic castration-resistant prostate cancer (mCRPC). It has been suggested that a combination of CPI and hypofractionated stereotactic body radiotherapy (SBRT) may work synergistically, and recent trials have supported this. We hypothesise that adding SBRT to CPI treatment can improve response rates in patients with mCRPC. METHODS AND ANALYSIS: The CheckPRO trial is an open-label, randomised, two-stage, phase II trial. We aim to enrol and randomise 80 evaluable patients with mCRPC who progressed following ≥2 lines of treatment. Enrolment started in November 2019 with 38 months expected enrolment period. The participants receive treatment for 52 weeks including four cycles of ipilimumab and nivolumab with or without concomitant SBRT (24 Gray in three fractions) to a single soft tissue or bone metastasis, followed by 10 cycles of nivolumab. Participants are followed until progression, death, or for 12 months after the end of treatment.Co-primary endpoints are the objective response rate and prostate-specific antigen (PSA) response rate. Secondary endpoints include safety, radiographic progression-free survival, clinical benefit rate, duration of response, PSA-progression-free survival beyond 12 weeks, quality of life and overall survival. Exploratory endpoints include translational analyses of tumour biopsies and consecutive blood samples. Biopsies from metastatic sites are collected at baseline, before the third treatment and at the end of treatment. Blood sampling for immune monitoring and circulating tumour DNA is performed consecutively at baseline and every radiographic assessment. ETHICS AND DISSEMINATION: This study follows the Helsinki Declaration and is approved by the Danish Ethics Committee System (journal no. H-19016100). All participants must receive written and oral information and provide a signed informed consent document prior to inclusion. The study results will be published in an international peer-review journal. TRIAL REGISTRATION NUMBER: EudraCT number: 2018-003461-34. CLINICALTRIALS: gov ID NCT05655715.

Wnt5a expression and prognosis in stage II-III colon cancer.

Cancer metastases accounts for most cancer deaths. The secreting glycoprotein Wnt5a impairs tumor cell migration and reduces invasiveness and metastasis. High Wnt5a expression in tumor cells is correlated to better outcomes in patients with breast, prostate and epithelial ovarian cancer. We aimed to investigate the association between the Wnt5a expression and outcomes in patients with colon cancer (CC) stage II/III. We performed a retrospective single-center study evaluating 345 patients with radical resection for primary CC, stage II/III, who started 6 months of adjuvant chemotherapy with 5-FU or capecitabine ±â€¯oxaliplatin between 2001 and 2015. Archived formalin-fixed paraffin embedded tumor tissue from resection specimens were stained with Wnt5a antibody using immunohistochemistry. Cytoplasmatic Wnt5a staining was assessed according to intensity and percentage of stained cells. Patients were divided in groups depending on high (n = 230) or low (n = 115) Wnt5a expression. Disease free survival (DFS) and overall survival (OS) were analyzed for the two groups using Kaplan-Meier plots and Long rank test. Patients with Wnt5a-negative tumors had significantly poorer performance status (PS) than patients with high Wnt5a expression (p = 0.046). No significant difference was seen between patients with low and high Wnt5a expression in terms of 5-year DFS (p = 0.517) or 5-year OS (p = 0.415). Poor PS was associated with lower DFS (p = 0.002) and OS (p < 0.001). In conclusion, we found no significant difference in prognosis for patients with stage II/III CC depending on their Wnt5a expression. Patients with Wnt5a-negative tumors had significant poorer PS than patients with higher levels. Poor PS was associated with lower DFS and OS.

Pre- and Perioperative Inflammatory Biomarkers in Older Patients Resected for Localized Colorectal Cancer: Associations with Complications and Prognosis.

The association between pre- and perioperative inflammatory biomarkers, major complications, and survival rates after resection of colorectal cancer (CRC) in older patients is largely unknown. The aim was to investigate age-dependent differences in these associations. Serum CRP, IL-6, and YKL-40 were measured preoperatively and on the first and second day after resection of CRC (stages I-III) in 210 older (≥70 years) and 191 younger patients (<70 years). The results from the complications was presented as an odds ratio (OR, with a 95% confidence interval (CI)) with logistic regression. Results from the mortality rates were presented as a hazard ratio (HR, with a 95% CI) using Cox proportional hazards regression. The preoperative inflammatory biomarkers were higher in the older vs. the younger patients. The risk of complications was increased in older patients with a high preoperative CRP (OR = 1.25, 95% CI 1.03-1.53), IL-6 (OR = 1.57, 95% CI 1.18-2.08), and YKL-40 (OR = 1.66, 95% CI 1.20-2.28), but not in younger patients. Mortality was higher in younger patients with high preoperative YKL-40 (HR = 1.66, 95% CI 1.06-2.60). This was not found in older patients. Elevated preoperative inflammatory biomarkers among older patients were associated with an increased risk of complications, but not mortality. Preoperative inflammatory biomarkers may be useful in assessing the risk of a complicated surgical course in older patients with CRC.

Specific CDK4/6 inhibition in breast cancer: a systematic review of current clinical evidence.

BACKGROUND: Loss of cell cycle control is a hallmark of cancer, and aberrations in the cyclin-dependent kinase-retinoblastoma (CDK-Rb) pathway are common in breast cancer (BC). Consequently, inhibition of this pathway is an attractive therapeutic strategy. The present review addresses efficacy and toxicity of CDK4/6 inhibition in BC. METHODS: A literature search was carried out using PubMed and EMBASE; data reported at international meetings and clinicaltrials.gov were included. RESULTS: Three specific CDK4/6 inhibitors palbociclib, abemaciclib and ribociclib are tested in clinical trials. A randomised phase II trial of palbociclib plus letrozole versus letrozole and a phase III of palbociclib plus fulvestrant versus fulvestrant showed significantly increased progression-free survival when compared with endocrine therapy alone in first-line and second-line treatment for advanced hormone receptor-positive HER2-negative BC. At the moment several phase III studies are ongoing with all three CDK4/6 inhibitors in hormone receptor-positive HER2-negative BC as well as other subtypes of BC. The predominant toxicity of agents was limited neutropenia. Other common adverse events were infections, fatigue and gastrointestinal toxicity. The toxicities seemed manageable. Yet data are too limited to differentiate between the compounds. Retinoblastoma protein (Rb) is considered a promising biomarker. CONCLUSION: CDK4/6 inhibition might represent a substantial advance for patients with hormone receptor-positive HER2-negative BC. Results must be confirmed in phase III trials before any firm conclusions can be made regarding the future influence of CDK4/6 inhibition. There is an urgent need for prospective biomarker-driven trials to identify patients for whom CDK4/6 inhibition is cost-effective.

Incidence and risk factors for capecitabine-induced symptomatic cardiotoxicity: a retrospective study of 452 consecutive patients with metastatic breast cancer.

OBJECTIVES: Case reports of capecitabine cardiotoxicity resemble those seen with intravenous 5-fluorouracil (5-FU) with chest pain as the predominant manifestation, but few studies of capecitabine cardiotoxicity are available. We aimed to determine the incidence of symptomatic cardiotoxicity from capecitabine in patients with breast cancer and to identify risk factors. METHODS: We reviewed medical records of consecutive women with breast cancer treated with capecitabine (1000 mg/m2 two times per day) from 2002 to 2012 at one institution. RESULTS: 22 of 452 patients (4.9%) (95% CI 2.9% to 6.9%) had symptoms of cardiotoxicity (chest pain: n=13, dyspnoea: n=9, palpitations: n=2). 11 patients had changes on ECG (atrial fibrillation: n=5, ST deviations: n=3, T-wave abnormalities: n=2 and QTc prolongation: n=1). 2 patients (0.4%) sustained acute myocardial infarction. 1 patient (0.2%) developed cardiac arrest with lethal outcome. 4 of 6 patients (66%) retreated with capecitabine had recurrent symptoms at retreatment. Cardiac comorbidity (p=0.001), hypercholesterolaemia (p=0.005) and current smoking (p=0.023) were risk factors for cardiotoxicity in univariate analyses and remained significant when adjusted for age. Patients with cardiac comorbidity were 5.5 times (95% CI 2.0 to 14.8) more likely to develop cardiotoxicity. In the subgroup of patients with apparently no cardiac comorbidity, the incidence of cardiotoxicity was lower (3.7%) and hypercholesterolaemia (p=0.035) and current smoking (p=0.020) were risk factors of cardiotoxicity. CONCLUSIONS: The incidence of cardiotoxicity from capecitabine resembles that of intravenous 5-FU (≈5%). Cardiac comorbidity, hypercholesterolaemia and current smoking were associated with development of cardiotoxicity.

[Follow-up after surgery for breast cancer]. / Opfølgning efter operation for primaer cancer mammae.

Routine follow-up of patients operated for primary breast cancer is a very expensive service, and it is necessary to clarify what purpose it serves. There is no evidence that routine follow-up of mastectomised patients influences morbidity, mortality, or quality of life. Only patients entering clinical trials or quality programmes should thus be followed-up. However, there is agreement in the literature that these patients should be offered follow-up in order to diagnose loco regional recurrences. Lumpectomised patients may be cured, if recurrence in the ipsilateral breast is detected at an early stage. Therefore, these patients should be followed up at regular visits. It is recommended that patients should be offered clinical examination every six months for the first five years, and once a year thereafter until ten years have elapsed since the primary treatment. Except for mammography of residual mamma at intervals of 12-18 months, there is no indication for any further paraclinical investigations.
