Nab-paclitaxel as First Line Treatment for NSCLC in Elderly Patients More Than 75 Years Old.

Introduction: Lung cancer is still the leading cause of cancer among cancer patients. Although there are novel therapies as second line treatment for NSCLC, there is an issue for elderly patients. Patients and Methods: We collected retrospectively data from 60 patients >75 years of age. Thirty of these patients received nab-paclitaxel and first line treatment and were compared to thirty patients that received only best supportive care. Results: The median life of patients at the date of disease progression, although increased by the administration of the drug (92 days versus 70) was not confirmed statistically significantly (Mann-Whitney test: W = 280, p = 0.138). The administration of drug seems to keep stable the biological condition of patients (McNemar's test: χ2 = 0.033, p = 0.99). Patients with chemotherapy the death rate was increased by 50% as compared to those with best supportive care (12 vs 8), the median life until the unfortunate event surpassed statistically significantly the latter (150 days of life as compared to 108, Mann-Whitney test: W = 57.5, p = 0.045). Discussion: Nab-paclitaxel as a monotherapy could be considered as a first line treatment option for patients > 75 years of age without any previous cardiological medical history when compared to best supportive care.

Diagnosing and treating pancoast tumors.

INTRODUCTION: According to the American College of Chest Physician definition, a Pancoast tumor is a tumor which invades any of the structures of the apex of the chest including the first thoracic ribs or periosteum, the lower nerve roots of the bronchial plexus, the sympathetic chain and stellate gaglion near the apex of the chest or the subclavian vessels. Pancoast tumors account for less than 3-5 % of lung tumors. Areas covered: We searched the libraries scopus and pub med and found 124 related manuscripts. From those we chose 18 to include in our short commentary based on the most up-date information included. Expert commentary: The present status of the recommended treatment of Pancoast tumors for patients medically fit for surgical resection is trimodality (chemoradiation followed by radical surgery excersion) as state of the art. Patients with unresectable Pancoast tumors and poor PS 4 or distant metastasis are candidate for radiation therapy for palliation of symptoms and best supportive care. In this mini review we will present up to date information regarding diagnosis and treatment management.

Monitoring changes in quality of life in patients with lung cancer by using specialised questionnaires: implications for clinical practice.

BACKGROUND: Quality of life (QoL) in lung cancer patients is overlooked due to the severity of the disease. Changes in factors comprising QoL need further exploration to determine therapy targets. METHODS AND MATERIALS: QoL was assessed in 282 patients referred to a specialised centre in Greece for chemotherapy using three reliable scales: Functional Assessment of Cancer Therapy-Lung (FACT-L, Greek version 4), Short Form (SF-36) Health Survey and Hospital Anxiety and Depression Scale (HAD)S. RESULTS: Comparing QoL scores, it was observed that in comparison to the first chemotherapy, there was a statistically significant deterioration in patients' physical well-being (p < 0.0001) at the following chemotherapies. In contrast, there was a statistically significant improvement in patients' emotional well-being (p < 0.0001), mental health (p < 0.0001) and social functioning (p = 0.006) in the chemotherapies following the first. Observations deriving from survival analyses agree with literature findings: small cell lung cancer (SCLC) patients had significantly shorter survival than non-SLSC (NSCLC) patients, initial performance status was consistent with survival, radiotherapy improved survival, existence of metastases hindered survival, and the number of chemotherapies and QoL scores were positively correlated with survival. CONCLUSIONS: Although patients' physical functioning deteriorated after chemotherapy, their psychological state, mental health and social functioning improved in comparison with their first chemotherapy. This may be due to the fear of the unknown and the stress patients experience before their treatment. Regarding survival analysis results, it could be stated that the better QoL scores, the longer the survival. The findings underline the importance of psychological support after diagnosis and during the initiation of treatment. This may result in a better QoL, hence leading to prolongation of survival.

New dilemmas in small-cell lung cancer TNM clinical staging.

BACKGROUND: Many patients with limited disease (LD) behave similarly to those with extensive disease (ED) from a prognostic point of view. On the other hand, a proportion of patients with ED small-cell lung cancer (SCLC) behave similarly to those with LD. PATIENTS AND METHODS: In this retrospective study analysis, 764 patients with proven SCLC were included and managed with the same therapeutic protocols. Of these patients, 278 (36.4%) had LD, while 486 (63.6%) had ED. RESULTS: No statistically significant difference was observed for survival for IA and IB disease stages (P = 0.254) and between IIA and IIB stages (P = 0.256) according to the new tumor, node, metastasis (TNM) staging classification classification. In addition, no statistical significant difference was observed for survival between patients with (IIA + IIB) and IIIA (P = 0.951), (IIA + IIIA, P = 0.658), and (IIB + IIIA, P = 0.573) stages. Statistical significant difference was observed for survival among the LD SCLC patients with (IA + IB), (IIA + IIB + IIIA), and IIIB stages (P < 0.001). Similarly, statistical significance was observed for ED SCLC patients with (IIA + IIB + IIIA), IIIB, and IV stages (P < 0.001). CONCLUSIONS: Although stratification of SCLC patients in LD and ED is generally satisfactory, the TNM staging system is recommended for more detailed prognostic information and treatment evaluation in these patients.

Subjective sleep quality in lung cancer patients before and after chemotherapy.

BACKGROUND: Sleep disturbances, such as difficulty in falling asleep, maintaining sleep, poor sleep efficiency, early awakening, and excessive daytime sleepiness, are common in patients with cancer. The aim of this study was to evaluate sleep characteristics in newly diagnosed lung cancer patients before and after three months of chemotherapy treatment. METHODS: Forty-nine patients with lung cancer, without brain metastasis, were included. Anthropometric and disease characteristics were collected. Upon diagnosis and after three months, a polysomnographic examination was conducted and the patients completed the Epworth Sleepiness Scale (ESS), the Pittsburgh Sleep Quality Index (PSQI), the Fatigue Severity Scale (FSS) and the Medical Research Council (MRC) dyspnoea scale. RESULTS: Before chemotherapy, the mean PSQI score was 7.1 ± 4, the FSS score was 3.92 ± 2, and the ESS score was 6.8 ± 4. The MRC score was low at 1.6 ± 1.1. A significant correlation between FSS and global PSQI was revealed (r = 0.424, P < 0.01), as well as with several of the PSQI components. After chemotherapy, no statistically significant change was observed in the PSQI (mean: 6.6 ± 4.5, t-score: 0.784, P = 0.438), or the FSS score (4.4 ± 2.2, t-score: -1.375, P = 0.177). Sleep efficiency was significantly reduced (P = 0.008), without any change in the distribution of sleep stages. CONCLUSION: The perception of sleep quality is poor among newly diagnosed lung cancer patients and is correlated with fatigue. After chemotherapy, self-reported sleep impairment is present and sleep efficiency is reduced, without significant change in sleep architecture.

Feasibility and effectiveness of inhaled carboplatin in NSCLC patients.

BACKGROUND: Inhaled chemotherapy is under investigation as an alternative therapeutic modality for Non-Small Cell Lung Cancer. METHODS: 60 NSCLC patients were randomized into 3 groups in this study. 20/60 patients (group A-control group) received I.V. chemotherapy (carboplatin AUC ≈ 5.5 D1); 20/60 (group B) received 2/3 of I.V. predicted carboplatin dose by I.V. infusion and the rest 1/3 as aerosol (jet nebulised D1); and 20/60 (group C) received all the predicted I.V. dose of carboplatin as aerosol in 3 equally divided fractions D1-3. In all patients I.V. docetaxel 100/m(2) was as well administered (D1). Lung functional tests were performed in all groups before chemotherapy in the 3rd and 6th cycles. RESULTS: Group B had a statistically significant increase in survival compared to control group A [275 days (95% CI 249-300) vs. 211 (95% CI 185-236)]. In regard to lung functional tests, a statistically significant decline was observed only in FEV1 of group C in 6 months compared to the initial measurement. CONCLUSIONS: Inhaled carboplatin could be given as an alternative root of pulmonary drug delivery in selected patients, but further randomized studies remain to prove whether the inhaled chemotherapy is an efficient and safe treatment modality.

The impact of zoledronic acid therapy in survival of lung cancer patients with bone metastasis.

Bone metastases occur in 20-40% of patients with lung cancer. Recent studies demonstrate a direct antiproliferative effect of 3rd generation bisphosphonates (BPs) on lung tumors, which may influence the survival. Therefore, we examined the clinical impact of zoledronic acid (ZOL; Zometa), a 3rd generation BP, with a focus on the survival, time to progression and pain effect in lung cancer patients with bone metastases. Lung cancer patients (n = 144, Stage IV) with evidence of metastasis bone scan were included. Eighty-seven of 144 experienced bone pain and received ZOL, 4 mg i.v. every 21 days (Group A), whereas the other 57 patients received no ZOL (Group B). All patients were treated with a combination chemotherapy consisted of docetaxel 100 mg/m(2) and carboplatin AUC = 6. It was found that Group A had a statistically significant longer survival (p < 0.01) when compared to Group B. A statistically significant positive correlation was found between the number of cycles of therapy with ZOL and total patient survival (p < 0.01, Pearson correlation) and time to progression (p < 0.01). Pain effect of ZOL had no significant difference between the 2 groups of patients (p > 0.05). Urine N-telopeptide of type I collagen (NTx) levels decreased in patients with NTx < or = 29 nM BCE/mM creatinine at baseline after treatment with ZOL. The results of our study suggest that the addition of ZOL increases overall survival in lung cancer patients with bone metastases. The longer period of receiving ZOL, the better effect on survival and time to progression.
