Increased quality of life in patients with breakthrough cancer pain after individualized therapy: the CAVIDIOM study.

Aim: To evaluate the quality of life (QoL) in patients with breakthrough cancer pain (BTcP) in Spanish medical oncology departments. Patients & methods: In a prospective, observational, multicenter study, we assessed QoL using the EQ-5D-5L instrument at baseline and after 15 and 30 days of individualized BTcP therapy, as well as BTcP characteristics and treatment. Results: Patients (n = 118) were mainly women, over 64 years old and with advanced cancer. QoL improved at 15 (p = 0.013) and 30 days (p = 0.011) versus baseline. Individualized BTcP therapy consisted mostly of rapid-onset opioids (transmucosal fentanyl at doses of 67-800 µg) according to the physician evaluation. BTcP improved, including statistically significant reductions in intensity, duration, number of episodes in the last 24 h and time to onset of BTcP relief. Conclusion: QoL increased after individualized pain therapy in patients with advanced cancer and BTcP in medical oncology departments.

Cancer patients can experience flares of pain, called breakthrough pain (BTcP), despite treatment with painkillers. Although BTcP can be excruciating, its intensity and other characteristics depend on several factors, including its treatment. However, even if treated, BTcP can impair quality of life for cancer patients. We assessed quality of life in 118 patients with advanced cancer and BTcP treated in 13 medical oncology departments across Spain. We treated BTcP with individualized therapy, taking into account both pain-related and patient-related factors. We also measured quality of life using a specific, widely-used questionnaire at the study visits: at onset of individualized pain therapy and after 3, 15 and 30 days' treatment. At each visit, flare-up pain therapy was adjusted or maintained as necessary. Throughout the study, quality of life and sleep quality improved for all participants. Furthermore, there was a greater reduction in intensity, duration and frequency of BTcP. The most common treatments for flare-ups were low doses of rapid-onset opioids (fentanyl given by sublingual, buccal or nasal administration), which were much better tolerated than high-dose opioids. Overall, the study showed that quality of life in patients with advanced cancer and BTcP increased after individualized pain therapy, mainly with low doses of rapid-onset opioids.

Efficacy of the MAGE-A3 cancer immunotherapeutic as adjuvant therapy in patients with resected MAGE-A3-positive non-small-cell lung cancer (MAGRIT): a randomised, double-blind, placebo-controlled, phase 3 trial.

BACKGROUND: Fewer than half of the patients with completely resected non-small-cell lung cancer (NSCLC) are cured. Since the introduction of adjuvant chemotherapy in 2004, no substantial progress has been made in adjuvant treatment. We aimed to assess the efficacy of the MAGE-A3 cancer immunotherapeutic in surgically resected NSCLC. METHODS: In this randomised, double-blind, placebo-controlled trial, we recruited patients aged at least 18 years with completely resected stage IB, II, and IIIA MAGE-A3-positive NSCLC who did or did not receive adjuvant chemotherapy from 443 centres in 34 countries (Europe, the Americas, and Asia Pacific). Patients were randomly assigned (2:1) to receive 13 intramuscular injections of recMAGE-A3 with AS15 immunostimulant (MAGE-A3 immunotherapeutic) or placebo during 27 months. Randomisation and treatment allocation at the investigator site was done centrally via internet with stratification for chemotherapy versus no chemotherapy. Participants, investigators, and those assessing outcomes were masked to group assignment. A minimisation algorithm accounted for the number of chemotherapy cycles received, disease stage, lymph node sampling procedure, performance status score, and lifetime smoking status. The primary endpoint was broken up into three co-primary objectives: disease-free survival in the overall population, the no-chemotherapy population, and patients with a potentially predictive gene signature. The final analyses included the total treated population (all patients who had received at least one treatment dose). This trial is registered with ClinicalTrials.gov, number NCT00480025. FINDINGS: Between Oct 18, 2007, and July 17, 2012, we screened 13 849 patients for MAGE-A3 expression; 12 820 had a valid sample and of these, 4210 (33%) had a MAGE-A3-positive tumour. 2312 of these patients met all eligibility criteria and were randomly assigned to treatment: 1515 received MAGE-A3 and 757 received placebo and 40 were randomly assigned but never started treatment. 784 patients in the MAGE-A3 group also received chemotherapy, as did 392 in the placebo group. Median follow-up was 38·1 months (IQR 27·9-48·4) in the MAGE-A3 group and 39·5 months (27·9-50·4) in the placebo group. In the overall population, median disease-free survival was 60·5 months (95% CI 57·2-not reached) for the MAGE-A3 immunotherapeutic group and 57·9 months (55·7-not reached) for the placebo group (hazard ratio [HR] 1·02, 95% CI 0·89-1·18; p=0·74). Of the patients who did not receive chemotherapy, median disease-free survival was 58·0 months (95% CI 56·6-not reached) in those in the MAGE-A3 group and 56·9 months (44·4-not reached) in the placebo group (HR 0·97, 95% CI 0·80-1·18; p=0·76). Because of the absence of treatment effect, we could not identify a gene signature predictive of clinical benefit to MAGE-A3 immunotherapeutic. The frequency of grade 3 or worse adverse events was similar between treatment groups (246 [16%] of 1515 patients in the MAGE-A3 group and 122 [16%] of 757 in the placebo group). The most frequently reported grade 3 or higher adverse events were infections and infestations (37 [2%] in the MAGE-A3 group and 19 [3%] in the placebo group), vascular disorders (30 [2%] vs 17 [3%]), and neoplasm (benign, malignant, and unspecified (29 [2%] vs 16 [2%]). INTERPRETATION: Adjuvant treatment with the MAGE-A3 immunotherapeutic did not increase disease-free survival compared with placebo in patients with MAGE-A3-positive surgically resected NSCLC. Based on our results, further development of the MAGE-A3 immunotherapeutic for use in NSCLC has been stopped. FUNDING: GlaxoSmithKline Biologicals SA.

Efficacy and safety of erlotinib versus chemotherapy in second-line treatment of patients with advanced, non-small-cell lung cancer with poor prognosis (TITAN): a randomised multicentre, open-label, phase 3 study.

BACKGROUND: Erlotinib, docetaxel, and pemetrexed are approved for the second-line treatment of non-small-cell lung cancer (NSCLC), but no head-to-head data from large clinical trials are available. We undertook the Tarceva In Treatment of Advanced NSCLC (TITAN) study to assess the efficacy and tolerability of second-line erlotinib versus chemotherapy in patients with refractory NSCLC. METHODS: TITAN was an international, randomised multicentre, open-label, phase 3 study that was done at 77 sites in 24 countries. Chemotherapy-naive patients with locally advanced, recurrent, or metastatic NSCLC received up to four cycles of first-line platinum doublet chemotherapy, after which patients with disease progression during or immediately after chemotherapy were offered enrolment into TITAN. Enrolled patients were randomly assigned (1:1) by a minimisation method to ensure balanced stratification, to receive erlotinib 150 mg/day or chemotherapy (standard docetaxel or pemetrexed regimens, at the treating investigators' discretion), until unacceptable toxicity, disease progression, or death. Patients were stratified by disease stage, Eastern Cooperative Oncology Group performance status, smoking history, and region of residence. The primary endpoint was overall survival in the intention-to-treat population. TITAN was halted prematurely because of slow recruitment. This study is registered with ClinicalTrials.gov, number NCT00556322. FINDINGS: Between April 10, 2006, and Feb 24, 2010, 2590 chemotherapy-naive patients were treated with first-line platinum doublet chemotherapy, of whom 424 had disease progression and were enrolled into TITAN. 203 patients were randomly assigned to receive erlotinib and 221 were assigned to receive chemotherapy. Median follow-up was 27·9 months (IQR 11·0-36·0) in the erlotinib group and 24·8 months (12·1-41·6) in the chemotherapy group. Median overall survival was 5·3 months (95% CI 4·0-6·0) with erlotinib and 5·5 months (4·4-7·1) with chemotherapy (hazard ratio [HR] 0·96, 95% CI 0·78-1·19; log-rank p=0·73). The adverse-event profile of each group was in line with previous studies. Rash (98/196 [50%] in the erlotinib group vs 10/213 [5%] in the chemotherapy group for all grades; nine [5%] vs none for grade 3 or 4) and diarrhoea (36 [18%] vs four [2%] for all grades; five [3%] vs none for grade 3 or 4) were the most common treatment-related adverse events with erlotinib, whereas alopecia (none vs 23 [11%] for all grades; none vs one [<1%] for grade 3/4) was the most common treatment-related adverse event with chemotherapy. INTERPRETATION: No significant differences in efficacy were noted between patients treated with erlotinib and those treated with docetaxel or pemetrexed. Since the toxicity profiles of erlotinib and chemotherapy differ, second-line treatment decisions should take into account patient preference and specific toxicity risk profiles.

Activity of topotecan given intravenously for 5 days every three weeks in patients with advanced non-small cell lung cancer pretreated with platinum and taxanes: a phase II study.

Topotecan, a semi-synthetic camptothecin analogue with topoisomerase I interaction, has shown to be an active agent in the treatment of advanced refractory lung cancer. This paper describes the authors' experience with this drug when used as a single agent in patients (pts) with advanced non-small cell lung cancer (NSCLC) refractory to platinum- and taxane-containing chemotherapy regimens. Thirty-five patients with NSCLC refractory to previous chemotherapy and KI ≥ 60% were included in the study. Their characteristics are as follows: median age of 52 years (range 43-69) and Karnofsky PS of 70 (60-80); 27 were male and 8 were female. Twenty-one (60%) patients had adenocarcinoma; eleven (31.4%), squamous cell, and three (8.5%), undifferentiated carcinoma. There was a median of two disease sites and two prior chemotherapy regimens. Topotecan was administered at a dose of 1.25 mg/m(2) I.V. daily for 5 days, repeated every 21 days until disease progression, maximal response, or intolerable toxicity. After 73 cycles, patients received a median of 2 treatment cycles (1-9). All patients except one were considered evaluable for toxicity; eight episodes (24%) of nausea/vomiting and two episodes (6%) of grade 1-2 asthenia, respectively, were reported. Four (12%) patients developed grade 1-2 anemia and two (6%) subjects suffered grade 3 anemia. Seven (21%) patients had grade 1-2 neutropenia and one (3%) presented grade 5 neutropenia. In 33 patients evaluable for activity of the 35 subjects included in the study; one (2.8%) presented a partial response; nine (25.7%) had stable disease, and 23 (65.7%) exhibited disease progression. Median time to progression and overall survival were 54 (12-210) and 70 (12-324) days, respectively. Intravenous topotecan at that dose and administration schedule displays scant activity in terms of response rate in individuals with advanced NSCLC previously treated with platinum and taxanes. The role and usefulness of chemotherapy in this setting warrants further investigation and confirmation through comparative studies.
