A randomised assessment of the use of a quality of life questionnaire with or without intervention in patients attending a thoracic cancer clinic.

The study examined the impact of using a quality of life (QoL) questionnaire during a clinic to identify QoL issues and to improve QoL. 138 patients were randomised (1:1:1) to either (1) an Intervention group that completed the European Organisation for Research and Treatment of Cancer-Core Quality of Life Questionnaire and Lung Cancer Module (EORTC QLQ-C30 and LC13) at baseline and received feedback during a clinic, (2) an Attention group that completed the questionnaire at baseline without feedback and (3) a Control group that did not complete the questionnaire. All patients completed the same questionnaire 6 weeks later and a contact diary during the study period. There was a significant difference between the Intervention and Control groups for the mean number of QoL issues identified at baseline (4.69 vs. 2.81, P = 0.006) and the mean number of actions taken (4.41 vs. 2.46, P = 0.004). At 6 weeks, there was no difference between the groups in global QoL (Intervention vs. Control group, P = 0.596; Attention vs. Control, P = 0.973). The results suggest that the completion of the EORTC QLQ-C30 LC13 with feedback improves communication and increases the number of QoL issues identified and actions taken. However, the intervention does not impact on QoL per se. Clinicaltrials.gov: NCT01213745.

Patient factors, health care factors and survival from lung cancer according to ethnic group in the south of London, UK.

International and UK data suggest that there are ethnic differences in survival for some malignancies. The aim of the present study was to identify any health inequalities related to lung cancer and ethnicity. Data on 423 patients with a diagnosis of lung cancer treated at a large specialist cancer hospital in London UK were analysed. Data on stage of disease at diagnosis, co-morbidities, socio-economic status, treatments received and survival were collected and examined for differences by ethnic group. There was a significant difference between black and minority ethnic (BME) patients and White-European patients in socio-economic status (Chi-square test P-value < 0.001). BME patients were over-represented in the most deprived socio-economic groups and under-represented in the most affluent. There were no significant differences in histology, stage of disease, co-morbidities and performance status or treatments received between the different ethnic groups. Ethnicity was not associated with survival. Significant prognostic factors for overall survival were performance status (P < 0.001), stage of disease (P = 0.001) and gender (P = 0.003). Our findings suggest that patients from BME groups are over-represented in more deprived socio-economic groups; however, this did not impact on significant prognostic factors or the treatments that they received. Importantly ethnicity did not influence survival.

A randomised study comparing the effectiveness of acupuncture or morphine versus the combination for the relief of dyspnoea in patients with advanced non-small cell lung cancer and mesothelioma.

BACKGROUND: Dyspnoea is one of the commonest symptoms of lung cancer. Opioids can reduce dyspnoea. This study investigates acupuncture for relief of breathlessness in lung cancer. METHODS: We performed a single-centre, randomised phase II study of 173 patients with non-small cell lung cancer or mesothelioma with dyspnoea score of ≥4 on visual analogue scale (VAS). Randomisation was to acupuncture alone (A), morphine alone (M) or both (AM). Acupuncture was administered at upper sternal, thoracic paravertebral, trapezius trigger points and LI4. Manubrial semi-permanent acupuncture studs were inserted and massaged when symptomatic. Arm A patients received rescue morphine. Primary end-point was proportion of patients achieving ≥1.5 improvement in VAS dyspnoea at 4 h. Measurements continued to day 14 and included VAS relaxation, line analogue rating (Lar) anxiety, hospital anxiety and depression and European Organisation for Research and Treatment of Cancer quality-of-life scores. RESULTS: Dyspnoea VAS improved ≥1.5 in 74%, 60% and 66% of arms A, M and AM, respectively, and was maintained in 45% at 2 weeks. There was no statistically significant difference between arms. VAS relaxation improved in arms A (1.06 points) and AM (1.48 points) compared to arm M (-0.19 points, p<0.001). At 7 d, the Lar anxiety score improved in arm A (1.5 points), arm AM (1.2 points) and arm M (no change, p=0.003). Fewer patients received at least one morphine dose in arm A compared with arm M or AM (21% versus 87% versus 87%, respectively, p<0.001). CONCLUSIONS: A, M and AM were effective in relieving dyspnoea. Acupuncture relieved anxiety and was morphine sparing, providing an alternative to morphine.

An unblinded, randomised phase II study of platinum-based chemotherapy with vitamin B12 and folic acid supplementation in the treatment of lung cancer with plasma homocysteine blood levels as a biomarker of severe neutropenic toxicity.

BACKGROUND: Vitamin B12 and folic acid (referred to as vitamin supplementation) improves the toxicity profile of pemetrexed containing regimens. Low baseline vitamin B12 and folate levels are reflected in a raised total homocysteine level (HC). Studies have suggested that pretreatment HC levels predict neutropenia toxicity. We have tested supplementation with vitamin B12 and folate in non-pemetrexed platinum-based regimens to decrease treatment-related toxicity and looked for a correlation between toxicity and change in homocysteine levels. PATIENT AND METHOD: Eighty-three patients with advanced lung cancer and malignant mesothelioma were randomly assigned to receive platinum-based chemotherapy with (arm A) or without (arm B) vitamin B12 and folic acid supplementation. The primary end point was grade 3/4 neutropenia and death within 30 days of treatment. Secondary end points included quality of life, overall survival (OS) and the relationship between baseline and post supplementation HC levels and toxicity. RESULTS: In the intention-to-treat population, no significant difference was seen between the two groups with respect to chemotherapy-induced grade 3/4 neutropenia and death within 30 days of chemotherapy (36% vs 37%; p=0.966, emesis (2% vs 6%; p=0.9) or OS (12.3 months vs 7 months; p=0.41). There was no significant difference in survival rates by baseline HC level (p=0.9). Decrease in HC with vitamin supplementation was less frequent than expected. High baseline HC levels decreased with vitamin supplementation in only 9/36 (25%) patients (successful supplementation). Post hoc analysis showed that patients in arm A who were successfully supplemented (9/36=25%) had less neutropenic toxicity (0% vs 69%; p=0.02) compared to unsupplemented patients. CONCLUSIONS: The addition of vitamin B12 and folic acid to platinum-containing regimens did not overall improve the toxicity, quality of life or OS. Rates of grade 3/4 neutropenia at 36/37% was as predicted. Further studies to increase the rate of successful supplementation and to further test the biomarker potential of post supplementation HC levels in predicting chemotherapy-induced neutropenia in platinum-based chemotherapy are warranted.

Under usage of zoledronic acid in non-small cell lung cancer patients with metastatic bone disease--a short communication.

BACKGROUND AND AIM: The use of zoledronic acid (ZA) is now recommended for patients with NSCLC and metastatic bone disease (MBD). We thus examined the rates of ZA administration in NSCLC looking specifically at the use of this drug with systemic chemotherapy (ZCt) and comparing overall survival between patients who had ZCt from diagnosis to those who had chemotherapy (Ct) alone. METHOD: In this retrospective audit, we analysed the data of 114 consecutive patients with stage IV NSCLC and MBD at presentation. Forty-three of these patients had received zoledronic acid and chemotherapy (ZCt) and 71 had received chemotherapy alone (Ct). RESULTS: Forty-three (37.7%, 43/114) of NSCLC patients diagnosed with MBD received ZA with their first chemotherapy (ZCt). Patients on ZCt, after adjustment for the planned prognostic factors (sites of disease, histology and PS), had better overall survival (OS), with a median of 34 weeks, compared to those who received chemotherapy alone, who had a median of 19 weeks (p = 0.03), HR = 0.60 (95%CI: 0.38-0.96). After adjusting for prognostic factors (sex, age. single versus doublet chemotherapy), ZCt patients still maintained a trend to better OS (p = 0.06) HR 0.63 (95%CI: 0.39-1.02) 34 versus 21 weeks. CONCLUSIONS: The percentage of patients with MBD treated with ZA at first chemotherapy (37.7%) is low. The addition of ZA increased OS in NSCLC patients with MBD in this audit. More formal policies and dedicated trials on the treatment of MBD in NSCLC patients need to be put in place.
