Effect on quality of life of cisplatin added to single-agent chemotherapy as first-line treatment for elderly patients with advanced non-small cell lung cancer: Joint analysis of MILES-3 and MILES-4 randomised phase 3 trials

OBJECTIVES

To evaluate the effect on quality of life (QOL) of the addition of cisplatin to single-agent chemotherapy in the treatment of elderly patients with advanced non-small cell lung cancer (NSCLC) enrolled in two parallel phase 3 trials, MILES-3 and MILES-4.

PATIENTS AND METHODS

Advanced NSCLC pts, >70 years old, performance status (PS) 0-1, were eligible. Patients were randomly assigned to chemotherapy without or with cisplatin. EORTC QLQ C30 and LC13 questionnaires were planned at baseline, end of cycle 1 and end of cycle 2 in both trials and were used for joint QOL analysis. Trial-specific data including questionnaires at non-shared time-points were used for additional analyses. Intention-to-treat strategy was applied. Analyses were adjusted for baseline QOL, stage, performance status, gender, age, size of centre, trial, histotype and non-platinum companion drug.

RESULTS

Overall, 458/531 pts (86%) answered baseline questionnaire and missing rates over treatment were slightly higher among patients receiving cisplatin. Mean change in sore mouth after cycle 2 was worse with cisplatin (P = 0.02). The size of differences between arms was in the small-medium range for peripheral neuropathy and alopecia (0.25 and 0.31 after one and 0.28 and 0.36 after two cycles, respectively) and for nausea/vomiting, sore mouth and dysphagia after two cycles (0.26, 0.38 and 0.25, respectively) always in the direction of worsening with cisplatin. Using a 10% change from baseline as clinically relevant threshold to categorize response, there was no significant difference between the arms. Time to deterioration of sore mouth and alopecia, with progression/death as competitive risk, was shorter with cisplatin (HR 1.72 95%CI 1.02-2.89, P = 0.04 and HR 1.84 95%CI 1.09-3.10, P = 0.02, respectively).

CONCLUSION

The addition of cisplatin to single agent chemotherapy worsens sore mouth and alopecia and does not improve any QOL items in elderly patients with advanced NSCLC.

Early versus delayed palliative/supportive care in advanced cancer: an observational study

OBJECTIVE

The positive impact of early palliative care interventions in advanced cancer patients has so far been largely evaluated in randomised controlled trials. This study aimed at providing information on the value of early palliative/supportive care, integrated with standard oncologic care, in a real-life setting.

METHODS

This was a retrospective observational study of 292 advanced cancer patients consecutively admitted at Carpi Hospital in Modena, Italy, between 2014 and 2017. For the purpose of this analysis, patients were classified into two groups (early and delayed palliative/supportive care patients), and analysed for different clinical indicators. Early and delayed palliative/supportive care were classified according to the time elapsed from advanced cancer diagnosis until palliative/supportive care start.

RESULTS

A total of 200 patients (68%), with at least three visits, were included in the analyses. The frequency of chemotherapy use in the last 60 days of life was 3.4% and 24.6% in the early and delayed groups, respectively (adjusted OR=0.1; 95% CI 0.0 to 0.4; p=0.002). The estimated survival probability at 1 year was 74.5% (95% CI 65.0% to 85.4%) and 45.5% (95% CI 37.6% to 55.0%), in the early and delayed groups, respectively. Performance status, pain and all the Edmonton Symptom Assessment Scale items, assessed at baseline and at 1 to 12 weeks after the intervention, showed significant improvement over time. However, no between-group differences were found with regard to symptom outcomes.

CONCLUSIONS

An earlier palliative/supportive care intervention was associated with reduced aggressiveness of therapy, in patients receiving community oncology care. Symptom burden was improved by early palliative/supportive care, independently of the timing of patient referral.

Scalp Cooling in Daily Clinical Practice for Breast Cancer Patients Undergoing Curative Chemotherapy: A Multicenter Interventional Study

Objective:

Chemotherapy-induced alopecia is a common and distressful side effect, especially among breast cancer patients. Scalp cooling (SC) can reduce hair loss during anthracycline- and taxane-based chemotherapy. This study assessed the effectiveness of SC in daily clinical practice in three Italian oncology units.

Methods:

From 2014 to 2016, we prospectively included 220 female early-stage breast cancer patients undergoing curative chemotherapy in combination with SC using the Paxman device. Effectiveness was defined as the severity of hair loss according to the Common Terminology Criteria for Adverse Events Version 4.0 as follows: Grade 0, no hair loss; Grade 1, <50% hair loss not requiring a wig; and Grade 2, ≥50% hair loss at each cycle and at completion of chemotherapy. The tolerability and safety were also evaluated.

Results:

The overall success rate of SC (hair loss Grade 0–1) was 68%. Severe hair loss was avoided in 89% of women receiving taxane-based chemotherapy and in 78% of women receiving both anthracyclines and taxanes. Among women undergoing anthracycline-based chemotherapy, 47% experienced hair preservation. SC was well tolerated, as only 20 patients discontinued SC for reasons other than hair loss.

Conclusions:

Our study confirmed that SC provides a reliable chance for breast cancer patients to keep their hair during taxane- and/or anthracycline-based chemotherapy.

Cisplatin-Based First-Line Treatment of Elderly Patients With Advanced Non-Small-Cell Lung Cancer: Joint Analysis of MILES-3 and MILES-4 Phase III Trials

Purpose To test the efficacy of adding cisplatin to first-line treatment for elderly patients with advanced non-small-cell lung cancer (NSCLC) within a combined analysis of two parallel phase III trials, MILES-3 and MILES-4. Patients and Methods Patients with advanced NSCLC who were older than age 70 years with Eastern Cooperative Oncology Group performance status 0 to 1 were randomly assigned to gemcitabine or pemetrexed, without or with cisplatin. In each trial, 382 events were required to detect a hazard ratio (HR) of death of 0.75, with 80% power and two-tailed α of .05. Trials were closed prematurely because of slow accrual, but the joint database allowed us to analyze the efficacy of cisplatin on the basis of intention-to-treat and adjusted by trial, histotype, non-platinum companion drug, stage, performance status, sex, age, and size of the study center. Results From March 2011 to August 2016, 531 patients (MILES-3, 299; MILES-4, 232) were assigned to gemcitabine or pemetrexed without (n = 268) or with cisplatin (n = 263). Median age was 75 years, 79% were male, and 70% had nonsquamous histology. At a median 2-year follow-up, 384 deaths and 448 progression-free survival events were recorded. Overall survival was not significantly prolonged with cisplatin (HR, 0.86; 95% CI, 0.70 to 1.05; P = .14) and global health status score of quality of life was not improved, whereas progression-free survival (HR, 0.76; 95% CI, 0.63 to 0.92; P = .005) and objective response rate (15.5% v 8.5%; P = .02) were significantly better. Significantly more severe hematologic toxicity, fatigue, and anorexia were found with cisplatin. Conclusion The addition of cisplatin to single-agent chemotherapy does not significantly prolong overall survival, and it does not improve global health status score of quality of life in elderly patients with advanced NSCLC.

Conflict of interest among Italian medical oncologists: a national survey

OBJECTIVES

To assess Italian medical oncologists' opinion on the implications of conflict of interest (COI) on medical education, care and research, and to evaluate their direct financial relationships.

DESIGN

National cross-sectional survey conducted between March and April 2017 among Italian oncologists.

SETTING

Online survey sponsored by the Italian College of Medical Oncology Chiefs through its website.

PARTICIPANTS

Italian oncologists who filled out an anonymous questionnaire including 19 items and individual and working characteristics.

MAIN OUTCOME MEASURE

The proportion of medical oncologists perceiving COI as an outstanding issue and those receiving direct payments from industry.

RESULTS

There were 321 respondents, representing 13% of Italian tenured medical oncologists. Overall, 62% declared direct payments from the pharmaceutical industry in the last 3 years. Sixty-eight per cent felt the majority of Italian oncologists have a COI with industry, but 59% suppose this is not greater than that of other specialties. Eighty-two per cent consider that most oncology education is supported by industry. More than 75% believe that current allocation of industry budget on marketing and promotion rather than research and development is unfair, but 75% consider it appropriate to receive travel and lodging hospitality from industry. A median net profit margin of €5000 per patient enrolled in an industry trial was considered appropriate for the employee institution. Sixty per cent agree to receive a personal fee for patients enrolled in industry trials, but 79% state this should be reported in the informed consent. Over 90% believe that scientific societies should publish a financial report of industry support. Finally, 79% disagree to being a coauthor of an article written by a medical writer when no substantial scientific contribution is made.

CONCLUSIONS

Among Italian oncologists COI is perceived as an important issue influencing costs, education, care and science. A more rigorous policy on COI should be implemented.

Elderly cancer patients’ preferences regarding the disclosure of cancer diagnosis. Experience of a single institution in Italy

The disclosure of a diagnosis of cancer is complex, particularly in older patients for reasons related to the wishes of the family, fear of discouraging the patient, or the patient's inability to understand the information. So our insight into older people's perspectives regarding the disclosure of their cancer diagnosis is fragmentary and inadequate. To examine the views of older adults regarding this issue, we performed a prospective observational study in an inpatient oncology clinic. From January 2006 to June 2006, a sample of 132 consecutive cancer patients aged over 70 years with a variety of solid tumors, recently diagnosed and mainly at an advanced stage, agreed to take part in a survey about the disclosure of the diagnosis of their disease. Of the 132 patients who verbally agreed to participate and were given questionnaires, 106 returned data. The majority of patients (64.1%) in this study wanted to be informed about the diagnosis of their disease also if it was cancer, and 58.5% were in fact informed about the exact nature of their disease. Male patients were more keen to know the diagnosis than female patients (P = 0.002) and they were in fact more informed about their diagnosis than female patients (P = 0.005). Patients with more formal education were more informed than patients with less formal education (P = 0.035). This study demonstrates that the preferences of older patients regarding cancer diagnosis disclosure are highly similar to those of younger people. Male patients and patients with more formal education were more informed than female patients and patients with less formal education.

Acupuncture As an Integrative Approach for the Treatment of Hot Flashes in Women With Breast Cancer: A Prospective Multicenter Randomized Controlled Trial (AcCliMaT)

PURPOSE

To determine the effectiveness of acupuncture for the management of hot flashes in women with breast cancer.

PATIENTS AND METHODS

We conducted a pragmatic, randomized controlled trial comparing acupuncture plus enhanced self-care versus enhanced self-care alone. A total of 190 women with breast cancer were randomly assigned. Random assignment was performed with stratification for hormonal therapy; the allocation ratio was 1:1. Both groups received a booklet with information about climacteric syndrome and its management to be followed for at least 12 weeks. In addition, the acupuncture group received 10 traditional acupuncture treatment sessions involving needling of predefined acupoints. The primary outcome was hot flash score at the end of treatment (week 12), calculated as the frequency multiplied by the average severity of hot flashes. The secondary outcomes were climacteric symptoms and quality of life, measured by the Greene Climacteric and Menopause Quality of Life scales. Health outcomes were measured for up to 6 months after treatment. Expectation and satisfaction of treatment effect and safety were also evaluated. We used intention-to-treat analyses.

RESULTS

Of the participants, 105 were randomly assigned to enhanced self-care and 85 to acupuncture plus enhanced self-care. Acupuncture plus enhanced self-care was associated with a significantly lower hot flash score than enhanced self-care at the end of treatment (P < .001) and at 3- and 6-month post-treatment follow-up visits (P = .0028 and .001, respectively). Acupuncture was also associated with fewer climacteric symptoms and higher quality of life in the vasomotor, physical, and psychosocial dimensions (P < .05).

CONCLUSION

Acupuncture in association with enhanced self-care is an effective integrative intervention for managing hot flashes and improving quality of life in women with breast cancer.

Randomized Trial of Low-Dose Morphine Versus Weak Opioids in Moderate Cancer Pain

PURPOSE

The WHO guidelines on cancer pain management recommend a sequential three-step analgesic ladder. However, conclusive data are lacking as to whether moderate pain should be treated with either step II weak opioids or low-dose step III strong opioids.

PATIENTS AND METHODS

In a multicenter, 28-day, open-label randomized controlled study, adults with moderate cancer pain were assigned to receive either a weak opioid or low-dose morphine. The primary outcome was the number of responder patients, defined as patients with a 20% reduction in pain intensity on the numerical rating scale.

RESULTS

A total of 240 patients with cancer (118 in the low-dose morphine and 122 in the weak-opioid group) were included in the study. The primary outcome occurred in 88.2% of the low-dose morphine and in 57.7% of the weak-opioid group (odds risk, 6.18; 95% CI, 3.12 to 12.24; P < .001). The percentage of responder patients was higher in the low-dose morphine group, as early as at 1 week. Clinically meaningful (≥ 30%) and highly meaningful (≥ 50%) pain reduction from baseline was significantly higher in the low-dose morphine group (P < .001). A change in the assigned treatment occurred more frequently in the weak-opioid group, because of inadequate analgesia. The general condition of patients, which was based on the Edmonton Symptom Assessment System overall symptom score, was better in the morphine group. Adverse effects were similar in both groups.

CONCLUSION

In patients with cancer and moderate pain, low-dose morphine reduced pain intensity significantly compared with weak opioids, with a similarly good tolerability and an earlier effect.

Adjuvant low-dose interleukin-2 (IL-2) plus interferon-α (IFN-α) in operable renal cell carcinoma (RCC): a phase III, randomized, multicentre trial of the Italian Oncology Group for Clinical Research (GOIRC)

There is currently no standard therapy to reduce the recurrence rate after surgery for renal cell carcinoma (RCC). The aim of this study was to assess efficacy and safety of adjuvant treatment with low doses of interleukin-2 (IL-2)+interferon-α (IFN-α) in operable RCC. The patients were randomized 1:1 to receive a 4-week cycle of low-dose IL-2+IFN-α or observation after primary surgery for RCC. Treatment cycles were repeated every 4 months for the first 2 years and every 6 months for the subsequent 3 years. The primary endpoint was recurrence-free survival (RFS); safety; and overall survival (OS) were secondary endpoints. ClinicalTrials.gov registration number was NCT00502034. 303/310 randomized patients (156 in the immunotherapy arm and 154 in the observation group) were evaluable at the intention-to-treat analyses. The 2 arms were well balanced. At a median follow-up of 52 months (range, 12-151 mo), RFS, and OS were similar, with an estimated hazard ratio (HR) of 0.84 [95% confidence interval (CI), 0.54-1.31; P=0.44] and of 1.07 (95% CI, 0.64-1.79; P=0.79), respectively in the 2 groups. Unplanned, subgroup analysis showed a positive effect of the treatment for patients with age 60 years and younger, pN0, tumor grades 1-2, and pT3a stage. Among patients with the combined presence of ≥ 2 of these factors, immunotherapy had a positive effect on RFS (HR=0.44; 95% CI, 0.24-0.82; P ≤ 0.01), whereas patients with <2 factors in the treatment arm exhibited a significant poorer OS (HR=2.27; 95% CI, 1.03-5.03 P=0.037). Toxicity of immunotherapy was mild and limited to World Health Organization grade 1-2 in most cases. Adjuvant immunotherapy with IL-2+IFN-α showed no RFS or OS improvement in RCC patients who underwent radical surgery. The results of subset analysis here presented are only hypothesis generating.

Pattern of care and effectiveness of treatment for glioblastoma patients in the real world: Results from a prospective population-based registry. Could survival differ in a high-volume center?

BACKGROUND

As yet, no population-based prospective studies have been conducted to investigate the incidence and clinical outcome of glioblastoma (GBM) or the diffusion and impact of the current standard therapeutic approach in newly diagnosed patients younger than aged 70 years.

METHODS

Data on all new cases of primary brain tumors observed from January 1, 2009, to December 31, 2010, in adults residing within the Emilia-Romagna region were recorded in a prospective registry in the Project of Emilia Romagna on Neuro-Oncology (PERNO). Based on the data from this registry, a prospective evaluation was made of the treatment efficacy and outcome in GBM patients.

RESULTS

Two hundred sixty-seven GBM patients (median age, 64 y; range, 29-84 y) were enrolled. The median overall survival (OS) was 10.7 months (95% CI, 9.2-12.4). The 139 patients ≤aged 70 years who were given standard temozolomide treatment concomitant with and adjuvant to radiotherapy had a median OS of 16.4 months (95% CI, 14.0-18.5). With multivariate analysis, OS correlated significantly with KPS (HR = 0.458; 95% CI, 0.248-0.847; P = .0127), MGMT methylation status (HR = 0.612; 95% CI, 0.388-0.966; P = .0350), and treatment received in a high versus low-volume center (HR = 0.56; 95% CI, 0.328-0.986; P = .0446).

CONCLUSIONS

The median OS following standard temozolomide treatment concurrent with and adjuvant to radiotherapy given to (72.8% of) patients aged ≤70 years is consistent with findings reported from randomized phase III trials. The volume and expertise of the treatment center should be further investigated as a prognostic factor.

A comparison between self-reported and GIS-based proxies of residential exposure to environmental pollution in a case-control study on lung cancer

In epidemiological studies both questionnaire results and GIS modeling have been used to assess exposure to environmental risk factors. Nevertheless, few studies have used both these techniques to evaluate the degree of agreement between different exposure assessment methodologies. As part of a case-control study on lung cancer, we present a comparison between self-reported and GIS-derived proxies of residential exposure to environmental pollution. 649 subjects were asked to fill out a questionnaire and give information about residential history and perceived exposure. Using GIS, for each residence we evaluated land use patterns, proximity to major roads and exposure to industrial pollution. We then compared the GIS exposure-index values among groups created on the basis of questionnaire responses. Our results showed a relatively high agreement between the two methods. Although none of these methods is the "exposure gold standard", understanding similarities, weaknesses and strengths of each method is essential to strengthen epidemiological evidence.

Gefitinib and afatinib treatment in an advanced non-small cell lung cancer (NSCLC) patient undergoing hemodialysis

Renal failure in cancer patients is not a rare clinical condition and often contraindicates anticancer drug treatment; moreover, chemotherapeutic drugs are frequently identified as possible iatrogenic cause of renal failure. Molecular therapies, when appropriate, could represent a therapeutic option for cancer patients with severe renal disease, but the lack of knowledge in this field, at present, limits their use in patients undergoing dialysis. Herein we describe a case, at our knowledge the first reported, of a patient with advanced lung adenocarcinoma on maintenance hemodialysis treated with gefitinib and then with afatinib; we also reviewed the literature on epidermal growth factor receptor (EGFR) tyrosine-kinase inhibitors (TKIs) used in NSCLC patients with concomitant renal impairment.

Double-blind, placebo-controlled, multicenter, randomized, phase IIb neoadjuvant study of letrozole-lapatinib in postmenopausal hormone receptor-positive, human epidermal growth factor receptor 2-negative, operable breast cancer

PURPOSE

This is a randomized, double-blind, placebo-controlled study aimed to evaluate the clinical and biologic effects of letrozole plus lapatinib or placebo as neoadjuvant therapy in hormone receptor (HR) -positive/human epidermal growth factor receptor 2 (HER2) -negative operable breast cancer.

METHODS

Ninety-two postmenopausal women with stage II to IIIA primary breast cancer were randomly assigned to preoperative therapy consisting of 6 months of letrozole 2.5 mg orally daily plus lapatinib 1,500 mg orally daily or placebo. Surgery was performed within 2 weeks from the last study medication. Clinical response was assessed by ultrasonography. Pre- and post-treatment samples were evaluated for selected biomarkers. Fresh-frozen tissue samples were collected for genomic analyses.

RESULTS

Numerically similar clinical response rates (partial + complete response) were observed (70% for letrozole-lapatinib and 63% for letrozole-placebo). Toxicities were generally mild and manageable. A significant decrease in Ki-67 and pAKT expression from baseline to surgery was observed in both arms. Overall, 34 patients (37%) had a mutation in PIK3CA exon 9 or 20. In the letrozole-lapatinib arm, the probability of achieving a clinical response was significantly higher in the presence of PIK3CA mutation (objective response rate, 93% v 63% in PIK3CA wild type; P = .040).

CONCLUSION

The combination of letrozole-lapatinib in early breast cancer was feasible, with expected and manageable toxicities. In unselected estrogen receptor-positive/HER2-negative patients, letrozole-lapatinib and letrozole-placebo resulted in a similar overall clinical response rate and similar effect on Ki-67 and pAKT. Our secondary end point findings of a significant correlation between PIK3CA mutation and response to letrozole-lapatinib in HR-positive/HER2-negative early breast cancer must now be independently confirmed.

Metronomic cyclophosphamide and capecitabine combined with lapatinib in heavily pretreated metastatic breast cancer (MBC) HER2-positive patients: 2-year update

e11515

Background: Current therapeutic goals for MBC, as an incurable disease, are symptoms and prolonged disease control together with good quality of life. Metronomic chemotherapy has shown efficacy in patients with metastatic breast cancer. We evaluated the efficacy and tolerability of the combination of anti-angiogenetic activity of metronomic chemotherapy with a tyrosine kinase inhibitor such as lapatinib in heavily pre-treated MBC HER-2 positive patients. Methods: Metastatic breast cancer patients HER-2 positive with CEA or Ca15.3 elevated, prior systemic therapy for advanced disease, ECOG performance status < 1 and life expectancy longer than 3 months. MBC patients were treated with metronomic oral capecitabine (1500 mg daily) and cyclophosphamide (50 mg daily) plus lapatinib (1250 mg daily). The treatment was given until disease progression. Primary objective was time to progression (TTP) and safety. Results: Fifteenpatients were included. Median age was 52 years old (range 42-77). Median number of previous chemotherapy lines was 5 (range 2-10). Median time to tumor progression was 6 months (2-14). No complete response was observed. Eight out of fiftten patients (60%) with pre-existing only bone metastases achieved a stable disease and/or partial response and were still on treatment after 6 month of therapy. At the same time 100% of these patients exhibited significant reduction of serum marker concentrations. No grade 3-4 skin toxicity was reported. Hematological and gastro-intestinal toxicity was well tolerated (G1-2). No reduction of dose was needed. Conclusions: The combination of lapatinib with metronomic chemotherapy may lead to effective palliation despite extensive pretreatment at least in bone metastatic patients. The treatment appears to be less toxic than lapatinib and capecitabine at full dosage, especially in heavily pretreated MBC patients. The preliminary results suggest the need of a clinical trial to confirm a role of this combination to delay lapatinib resistance.
