Clinical significance and treatment of skin rash from erlotinib in non-small cell lung cancer patients: results of an Experts Panel Meeting.

Advances in the knowledge of tumor biology and mechanisms of oncogenesis has granted the singling out of several molecular targets for non-small cell lung cancer (NSCLC) treatment. Among these targets, epidermal growth factor receptor (EGFR), or HER1, has received particular attention in lung cancer treatment. Erlotinib, an orally available inhibitor of EGFR tyrosine kinase in a phase III randomized placebo-controlled trial (BR.21), has been proven to prolong survival in NSCLC patients after first or second line chemotherapy. Skin rash is the most common adverse event associated with erlotinib treatment and it is often cause of negative impact on patients' quality of life. There is no specific treatment for this toxicity due to the lack of evidence-based data and recommendations. A panel of Italian oncologists, who had participated to clinical trials and to the Expanded Access Program for erlotinib in NSCLC treatment, and dermatologists with experience with cutaneous toxicity from EGFR inhibitors, attended a Meeting held in Rome on December 2006 to discuss skin rash from erlotinib and to provide suggestions for managing this frequent side-effect.

Gemcitabine, ifosfamide and paclitaxel in advanced/metastatic non-small cell lung cancer patients: a phase II study.

UNLABELLED: Although platinum-based two-drug combinations represent the elective therapeutic approach for advanced/metastatic NSCLC, there is still interest in exploring the efficacy and tolerability of platinum-free combinations including third generation agents in selected NSCLC population. Based on the satisfying activity of gemcitabine (G), ifosfamide (I) and paclitaxel (T) as single agents in NSCLC, we have designed a phase II study to explore an alternative approach to platinum-containing regimens using a combination of these three drugs. To investigate the activity/toxicity of T 175 mg/m2 on day 1, I 3 g/m2 on day 1 (with Mesna uroprotection) and G 1,000 mg/m2 on day 1-8, every 3 weeks in the treatment of advanced/metastatic NSCLC, 46 patients (38 male, 8 female) with NSCLC were enrolled: mean age 58 (range 33-70); Stage IIIB/IV=15/31; ECOG PS 0-1/2=31/15; HISTOLOGY: adenocarcinoma=20, squamous=14, large cell=3, NSCLC=8, adenosquamous=1. A total of 221 cycles have been administered (median number 4.8 for patients). In intent-to-treat analysis, partial response was achieved in 17 patients (36.95%), stable disease and progressive disease was detected in 16 (34.78%) and 10 (21.73%) patients, respectively. Time to progression was 30.9 weeks; median survival time was 42.7 weeks; the survival rates at 12 and 18 months were 34.79 and 15.21%, respectively. No toxic deaths occurred. No patients experienced grade 4 neutropenia and thrombocytopenia. Neutropenia grade 3 occurred in 10 patients (21.7%); Anemia grade 3 in 1 (2.1%); Thrombocytopenia grade 2 in two patients (4.3%) and grade 3 in one (2.1%). Peripheral neuropathy grade 1 occurred in ten (21.7%) and grade 2 in two patients (4.3%). Additional non-haematological toxicities were mild nausea, emesis and fatigue. GIT is well tolerated and active regimen in both advanced and metastatic NSCLC. These data suggest future investigations for GIT schedule as a possible alternative to platinum-based regimens in selected advanced/metastatic NSCLC patients where survival, tolerability and quality of life are the primary goals.

A randomised clinical trial of two docetaxel regimens (weekly vs 3 week) in the second-line treatment of non-small-cell lung cancer. The DISTAL 01 study.

Docetaxel (75 mg m(-2) 3-weekly) is standard second-line treatment in advanced non-small-cell lung cancer (NSCLC) with significant toxicity. To verify whether a weekly schedule (33.3 mg m(-2) for 6 weeks) improved quality of life (QoL), a phase III study was performed with 220 advanced NSCLC patients, < or =75 years, ECOG PS < or =2. QoL was assessed by EORTC questionnaires and the Daily Diary Card (DDC). No difference was found in global QoL scores at 3 weeks. Pain, cough and hair loss significantly favoured the weekly schedule, while diarrhoea was worse. DDC analysis showed that loss of appetite and overall condition were significantly worse in the 3-week arm in the first week, while nausea and loss of appetite were more severe in the weekly arm in the third week. Response rate and survival were similar, hazard ratio of death in the weekly arm being 1.04 (95% CI 0.77-1.39). A 3-weekly docetaxel was more toxic for leukopenia, neutropenia, febrile neutropenia and hair loss; any grade 3-4 haematologic toxicity was significantly more frequent in the standard arm (25 vs 6%). The weekly schedule could be preferred for patients candidate to receive docetaxel as second-line treatment for advanced NSCLC, because of some QoL advantages, lower toxicity and no evidence of strikingly different effect on survival.

Supportive care in patients with advanced non-small-cell lung cancer.

The present study describes supportive care (SC) in patients with advanced non-small-cell lung cancer (NSCLC), evaluating whether it is affected by concomitant chemotherapy, patient's performance status (PS) and age. Data of patients enrolled in three randomised trials of first-line chemotherapy, conducted between 1996 and 2001, were pooled. The analysis was limited to the first three cycles of treatment. Supportive care data were available for 1185 out of 1312 (90%) enrolled patients. Gastrointestinal drugs (45.7%), corticosteroids (33.4%) and analgesics (23.8%) were the most frequently observed categories. The mean number of drugs per patient was 2.43; 538 patients (45.4%) assumed three or more supportive drugs. Vinorelbine does not produce substantial variations in the SC pattern, while cisplatin-based treatment requires an overall higher number of supportive drugs, with higher use of antiemetics (41 vs 27%) and antianaemics (10 vs 4%). Patients with worse PS are more exposed to corticosteroids (42 vs 30%). Elderly patients require drugs against concomitant diseases significantly more than adults (20 vs 7%) and are less frequently exposed to antiemetics (12 vs 27%). In conclusion, polypharmacotherapy is a relevant issue in patients with advanced NSCLC. Chemotherapy does not remarkably affect the pattern of SC, except for some drugs against side effects. Elderly patients assume more drugs for concomitant diseases and receive less antiemetics than adults.
