Survivorship program including long-term toxicities and quality-of-life development over 10 years in a randomized trial in operable stage III non-small-cell lung cancer (ESPATUE).

Over 40% stage-III non-small-cell lung cancer (NSCLC) patients (pts) experience 5-year survival following multimodality treatment. Nevertheless, little is known about relevant late toxicities and quality-of-life (QoL) in the further long-term follow-up. Therefore, we invited pts from our randomized phase-III trial (Eberhardt et al., Journal of Clinical Oncology 2015) after 10 years from diagnosis to participate within a structured survivorship program (SSP) including follow-up imaging, laboratory parameters, cardio-pulmonary investigations, long-term toxicity evaluations and QoL questionnaires. Of 246 pts initially accrued, 161 were considered potentially resectable following the induction therapy and were randomized (80 to arm A: definitive chemoradiation; 81 to arm B: definitive surgery; 85 not randomized for different reasons; group C). 31 from 37 pts still alive after 10 years agreed to the SSP (13 in A; 12 in B; 6 in C). Clinically relevant long-term toxicities (grade 3 and 4) were rarely observed with no signal favoring any of the randomization arms. Furthermore, available data from the global QoL analysis did not show a signal favoring any definitive locoregional approach (Mean QoL in SSP A pts: 56.41/100, B pts: 64.39/100) and no late decline in comparison to baseline and early 1-year follow-up. This is the first comprehensive SSP of very late survival follow-up reported in stage-III NSCLC treated within a randomized multimodality trial and it may serve as important baseline information for physicians and pts deciding for a locoregional treatment option.

[Carcinoma, tuberculosis, atypical pneumonia - or may be pulmonary tularemia? Two case reports]. / Karzinom, Tuberkulose, atypische Pneumonie ­ oder vielleicht pulmonale Tularämie? Zwei Fallberichte.

Tularemia is a rare zoonotic disease, endemic in rural areas all over Germany. It's clinical manifestation following inhalation of infectious aerosols may resemble pulmonary neoplasia, other atypical pneumonias or tuberculosis. Here we describe two representative cases with pulmonary tularemia.

Experience with afatinib in patients with non-small cell lung cancer progressing after clinical benefit from gefitinib and erlotinib.

BACKGROUND: Afatinib, an irreversible ErbB family blocker, demonstrated superiority to chemotherapy as first-line treatment in patients with EGFR-mutated non-small cell lung cancer (NSCLC). Afatinib is also active in patients progressing on EGFR tyrosine kinase inhibitors (EGFR-TKIs). We report the results of a large cohort of NSCLC patients receiving afatinib within a compassionate-use program (CUP). PATIENTS AND METHODS: Patients with advanced NSCLC progressing after one line or more of chemotherapy and one line or more of EGFR-TKI treatment with either an EGFR mutation or documented clinical benefit were enrolled. Data collection was not monitored or verified by central review. The intention of this CUP was to provide controlled preregistration access to afatinib for patients with life-threatening diseases and no other treatment option. RESULTS: From May 2010 to October 2013, 573 patients (65% female; median age: 64 years [range: 28-89 years]) were enrolled, with strong participation of community oncologists. Comorbidities were allowed, including second malignancies in 11% of patients. EGFR mutation status was available in 391 patients (72%), and 83% tested mutation positive. Median time to treatment failure (TTF) of 541 patients treated with afatinib was 3.7 months (range: 0.0 to >29.0 months). Median TTF was 4.0 and 2.7 months in patients with adenocarcinomas and squamous cell carcinomas, respectively, and 4.6 months in patients with EGFR-mutated NSCLC. Adverse events were generally manageable. CONCLUSION: Afatinib was able to be given in a real-world setting to heavily pretreated patients with EGFR-mutated or EGFR-TKI-sensitive NSCLC. Acknowledging the constraints of data collection in a CUP, afatinib appears to be safe and to confer some clinical benefit in this population.

Primary pulmonary synovial sarcoma: a rare primary pulmonary tumor.

INTRODUCTION: Pulmonary sarcomas overall are very uncommon and comprise only 0.5 % of all primary lung malignancies. The diagnosis is established only after sarcoma-like primary lung malignancies and a metastatic extrathoracic sarcoma have been excluded. Synovial sarcoma accounts for ~8 % of soft-tissue sarcomas. Synovial sarcoma arising from the pleura has rarely been reported. METHODS: We report a case of a 58-year-old woman who complained of right-sided chest pain and shortness of breath. Chest CT scan revealed a large heterogeneous mass, occupying most of the right hemithorax. Histologic diagnosis was supplemented by interphase cytogenetic (FISH) analysis. RESULTS: Computed tomography guided Tru-cut biopsy was suspicious for a sarcomatous or fibrous malignancy. However, intraoperative frozen-section diagnostics confirmed the diagnosis of a sarcoma. Immunohistochemistry showed that tumor cells expressed epithelial membrane antigen, CD99 and BCL2. Based on immunohistochemistry, the diagnosis of synovial sarcoma was suspected and was confirmed by FISH analysis. The patient was treated with right upper bilobectomy. Due to R1-resection status, postsurgical systemic chemotherapy was administered. CONCLUSIONS: Primary pulmonary synovial sarcoma is a rare primary lung tumor. Due to extensive size of the tumor with pleural and mediastinal invasion only a R1-resection status could be achieved by thoracic surgery.

A randomized, multicenter phase II study comparing efficacy, safety and tolerability of two dosing regimens of cisplatin and pemetrexed in patients with advanced or metastatic non-small-cell lung cancer.

BACKGROUND: Pemetrexed and cisplatin is a first-line standard in non-squamous non-small-cell lung cancer without targetable mutations. It became the backbone of checkpoint-inhibitor-chemotherapy combinations. Single high doses of cisplatin pose toxicity risks and require hyperhydration, potentially prolonging outpatient application. The aim of this study was to compare efficacy, safety and tolerability of split-dose cisplatin with the standard schedule. METHODS: Patients with metastatic non-squamous non-small-cell lung cancer were randomly assigned to up to six 21-day cycles of pemetrexed 500 mg/m2 and cisplatin 75 mg/m2 on day 1 (arm A), or pemetrexed 500 mg/m2 (day 1) and cisplatin 40 mg/m2 (day 1 + 8, arm B), followed by pemetrexed maintenance. Primary endpoint was objective response rate. Secondary objectives were overall survival, progression-free survival, time to progression, treatment compliance, toxicity profile, and quality of life. RESULTS: We enrolled 130 patients (129 evaluable). Median cycle numbers in A and B were six (1-6) and five (1-6). Dose intensities were comparable between arms. More patients in A received pemetrexed maintenance (24.2% versus 11.1%). With 16 (24.2%) in A and 19 (30.2%) patients in B achieving objective responses [odds ratio 0.74 (0.34-1.62), p = 0.55] the primary endpoint was met. Overall survival was not different between arms (median 14.4 versus 14.9 months); [HR = 1.07; (0.68-1.68), p = 0.78]. Median progression-free survival was 7.0 months in A and 6.2 months in B [HR = 1.63; (1.17-2.38); p = 0.01]. Adverse events of CTCAE grade ⩾3, particularly hematological, were more frequent in B. No difference in grade 4 and 5 infections between arms was noted. Treatment-related asthenia and nausea/vomiting of any grade were more frequent in A. Global health status, fatigue and constipation measured on day 1 of cycle 4 demonstrated superior scores in B. CONCLUSION: Pemetrexed and split-dose cisplatin is safe and effective. Advantages of split-dose cisplatin with regard to specific toxicities allow personalization of this important chemotherapy backbone.

A Randomized-Controlled Phase 2 Study of the MET Antibody Emibetuzumab in Combination with Erlotinib as First-Line Treatment for EGFR Mutation-Positive NSCLC Patients.

INTRODUCTION: The hepatocyte growth factor receptor mesenchymal-epithelial transition (MET) is reported to be a negative prognostic marker in EGFR-mutant NSCLC and involved in resistance to EGFR inhibitors. Emibetuzumab, a humanized immunoglobulin G4 monoclonal bivalent MET antibody, blocks ligand-dependent and ligand-independent hepatocyte growth factor/MET signaling. This phase 2 study compared erlotinib with and without emibetuzumab in first-line treatment of EGFR-mutant metastatic NSCLC. METHODS: Patients with stage IV EGFR-mutant NSCLC and disease control after an 8-week lead-in with erlotinib (150 mg daily) were randomized to continue taking erlotinib with or without emibetuzumab (750 mg every 2 weeks). The primary end point was progression-free survival (PFS). Additional end points included overall survival, overall response rate, safety, pharmacokinetics, and exploratory analysis of MET expression. RESULTS: No significant difference in median PFS was observed in the intent-to-treat population (9.3 months with emibetuzumab + erlotinib versus 9.5 months with erlotinib monotherapy [hazard ratio (HR) = 0.89, 90% confidence interval (CI): 0.64-1.23]). The median overall survival was 34.3 months with emibetuzumab plus erlotinib versus 25.4 months with erlotinib (HR = 0.74, 90% CI: 0.49-1.11). Emibetuzumab plus erlotinib was well tolerated, with peripheral edema and mucositis as the only adverse events occurring 10% or more frequently relative to erlotinib. Exploratory post hoc analysis showed an improvement of 15.3 months in median PFS for the 24 patients with the highest MET expression (MET expression level of 3+ in ≥90% of tumor cells) (20.7 with emibetuzumab + erlotinib versus 5.4 months with erlotinib [HR = 0.39, 90% CI: 0.17-0.91]). CONCLUSIONS: No statistically significant difference in PFS was noted in the intent-to-treat population. Exploratory analysis confirmed that high MET expression is a negative prognostic marker for patients treated with erlotinib, indicating that emibetuzumab plus erlotinib may provide clinically meaningful benefit.

Clinical Experience of Immunotherapy Treatment: Efficacy and Toxicity Analysis of the Compassionate Use Program of Nivolumab in Patients with Advanced Squamous Cell Non-Small Cell Lung Cancer.

BACKGROUND: Anti-PD1 monoclonal antibody nivolumab is an approved therapy option for the treatment of advanced squamous cell non-small cell lung cancer (SQ-NSCLC) patients. Data outside clinical trials about therapy efficacy and safety in later therapy line treatments have rarely been described until now. METHODS: We performed a retrospective data analysis of patients who were enrolled into the nivolu-mab Compassionate Use Program (CUP) in Germany. Sufficient clinical data of 40 patients were available for efficacy and safety analysis. RESULTS: Overall, 47.5% of all treated patients were not affected by any adverse events (AEs); 17.5% of patients suffered from severe AEs. The 1-year survival rate was 61.3%. Estimated median progression-free survival (PFS) was 5.3 months. Patients who received nivolumab as third or later therapy line treatment (77.5%) achieved similar median PFS and 12-month overall survival rate of 52%. CONCLUSION: Our findings of immunotherapy treatment outside clinical trials support the results of studies in the past and confirm the efficacy and favorable toxicity profile of nivolumab treatment in advanced SQ-NSCLC patients. In addition, we can present some rarely described information about nivolumab treatment of heavily pretreated patients, which provides some evidence that immunotherapy could also be useful in later therapy lines.

Efficacy and safety analysis of the German expanded access program of osimertinib in patients with advanced, T790M-positive non-small cell lung cancer.

PURPOSE: Osimertinib, a third-generation irreversible mutant-selective inhibitor of EGFR kinase activity was clinically evaluated in the AURA trials, where it showed high clinical efficacy and a favorable toxicity profile in patients with acquired exon 20-EGFR pT790M mutation. We provide the clinical data of the German expanded access program that further characterizes the efficacy and safety of osimertinib in a heterogeneous patient population outside clinical trials. METHODS: We performed a retrospective data analysis on patients who were included into the German osimertinib EAP. RESULTS: Of 81 patients enrolled, 51 patients (62.9%) with sufficient case report form data were available for efficacy and safety analysis. Unconfirmed overall response rate was 80.0% with 2 patients (3.9%) achieving a complete remission and 37 patients (72.5%) having a partial remission. Disease control rate was 95.9% and only two patients showed refractory disease. Disease control rate did not correlate with clinical characteristics and was independent of number as well as type of the previous therapy line(s). Estimated progression-free survival was 10.1 months (95% CI 9.2-11.0 months). Osimertinib showed a favorable toxicity profile with no dose reductions in our observation period, even in patients with low performance status. Median survival from first diagnosis to data cut-off was 47.3 months (95% CI 43.3-51.9 months). Repeated tissue/liquid biopsy of three patients in our cohort who showed disease progression revealed an amplification of MET. CONCLUSIONS: We confirm safety and efficacy of osimertinib with high response rates among all subgroups, including patients with poor performance status and multiple prior therapy lines. Amplification of MET might mediate acquired resistance to osimertinib.

Efficacy and Safety of Ramucirumab With Docetaxel Versus Placebo With Docetaxel as Second-Line Treatment of Advanced Non-Small-Cell Lung Cancer: A Subgroup Analysis According to Patient Age in the REVEL Trial.

INTRODUCTION: Ramucirumab, a recombinant human immunoglobulin G1 monoclonal antibody receptor antagonist designed to block the ligand-binding site of vascular endothelial growth factor receptor-2 (VEGFR-2), was evaluated as second-line treatment in combination with docetaxel in patients with non-small-cell lung cancer in the REVEL trial (NCT01168973). Ramucirumab significantly improved overall survival (OS) and progression-free survival (PFS). We report age subgroup analysis results primarily on the basis of a 65-year cutoff. PATIENTS AND METHODS: Patients were randomized 1:1 to ramucirumab with docetaxel or placebo with docetaxel (n = 1253). Of these, 798 were younger than 65 years (ramucirumab, n = 391; control, n = 407) and 455 were 65 years or older (ramucirumab, n = 237; control, n = 218). Treatment comprised 21-day cycles of 75 mg/m2 docetaxel with 10 mg/kg ramucirumab or placebo. Prespecified age subgroup analyses were performed, including OS, PFS, and objective response rate. Quintiles age analysis was conducted to establish a relationship between efficacy and age. The Lung Cancer Symptom Scale (LCSS) measured quality of life outcomes. Safety was assessed according to adverse events (AEs). RESULTS: Patients younger than 65 years showed favorable OS outcomes with ramucirumab treatment (hazard ratio [HR], 0.74; 95% confidence interval [CI], 0.62-0.87; P < .001) and PFS (HR, 0.68; 95% CI, 0.59-0.79; P < .001). In patients 65 years or older, benefits of ramucirumab were not as evident; after model adjustment for prognostic factors, OS and PFS HRs were 0.96 (95% CI, 0.77-1.21; P = .04) and 0.87 (95% CI, 0.71-1.05; P = .03), respectively. Age analysis according to quintiles showed HRs favoring ramucirumab for all age groupings. LCSS scores and AEs did not considerably differ between age groups. CONCLUSION: In this subgroup analysis, true treatment effect differences on the basis of age have not been established, and treatment should not be deterred solely because of age.

Phase III Study of Surgery Versus Definitive Concurrent Chemoradiotherapy Boost in Patients With Resectable Stage IIIA(N2) and Selected IIIB Non-Small-Cell Lung Cancer After Induction Chemotherapy and Concurrent Chemoradiotherapy (ESPATUE).

PURPOSE: Concurrent chemoradiotherapy with or without surgery are options for stage IIIA(N2) non-small-cell lung cancer. Our previous phase II study had shown the efficacy of induction chemotherapy followed by chemoradiotherapy and surgery in patients with IIIA(N2) disease and with selected IIIB disease. Here, we compared surgery with definitive chemoradiotherapy in resectable stage III disease after induction. PATIENTS AND METHODS: Patients with pathologically proven IIIA(N2) and selected patients with IIIB disease that had medical/functional operability received induction chemotherapy, which consisted of three cycles of cisplatin 50 mg/m(2) on days 1 and 8 and paclitaxel 175 mg/m(2) on day 1 every 21 days, as well as concurrent chemoradiotherapy to 45 Gy given as 1.5 Gy twice daily, concurrent cisplatin 50 mg/m(2) on days 2 and 9, and concurrent vinorelbine 20 mg/m(2) on days 2 and 9. Those patients whose tumors were reevaluated and deemed resectable in the last week of radiotherapy were randomly assigned to receive a chemoradiotherapy boost that was risk adapted to between 65 and 71 Gy in arm A or to undergo surgery (arm B). The primary end point was overall survival (OS). RESULTS: After 246 of 500 planned patients were enrolled, the trial was closed after the second scheduled interim analysis because of slow accrual and the end of funding, which left the study underpowered relative to its primary study end point. Seventy-five patients had stage IIIA disease and 171 had stage IIIB disease according to the Union for International Cancer Control TNM classification, sixth edition. The median age was 59 years (range, 33 to 74 years). After induction, 161 (65.4%) of 246 patients with resectable tumors were randomly assigned; strata were tumor-node group, prophylactic cranial irradiation policy, and region. Patient characteristics were balanced between arms, in which 81 were assigned to surgery and 80 were assigned to a chemoradiotherapy boost. In arm B, 81% underwent R0 resection. With a median follow-up after random assignment of 78 months, 5-year OS and progression-free survival (PFS) did not differ between arms. Results were OS rates of 44% for arm B and 40% for arm A (log-rank P = .34) and PFS rates of 32% for arm B and 35% for arm A (log-rank P = .75). OS at 5 years was 34.1% (95% CI, 27.6% to 40.8%) in all 246 patients, and 216 patients (87.8%) received definitive local treatment. CONCLUSION: The 5-year OS and PFS rates in randomly assigned patients with resectable stage III non-small-cell lung cancer were excellent with both treatments. Both are acceptable strategies for this good-prognosis group.

Phase II trial of a trimodality regimen for stage III non-small-cell lung cancer using chemotherapy as induction treatment with concurrent hyperfractionated chemoradiation with carboplatin and paclitaxel followed by subsequent resection: a single-center study.

PURPOSE We started a phase II trial of induction chemotherapy and concurrent hyperfractionated chemoradiotherapy followed by either surgery or boost chemoradiotherapy in patients with advanced, stage III disease. The purpose is to achieve better survival in the surgery group with minimum morbidity and mortality. PATIENTS AND METHODS Patients treated from 1998 to 2002 with neoadjuvant chemoradiotherapy and surgical resection for stage III NSCLC were analyzed. The treatment consisted of four cycles of induction chemotherapy with carboplatin/paclitaxel followed by chemoradiotherapy with a reduced dose of carboplatin/paclitaxel and accelerated hyperfractionated radiotherapy with 1.5 Gy twice daily up to 45 Gy. After restaging, operable patients underwent thoracotomy. Inoperable patients received chemoradiotherapy up to 63 Gy. Study end points included resectability, pathologic response, and survival. Results One hundred twenty patients were enrolled; 25% patients had stage IIIA, 73% had stage IIIB, and 2% stage IV. After treatment, 47.5% had downstaging, 29.2% had stable disease, and 23.3% had progressive disease. Thirty patients (25%) were not eligible for operation because of progressive disease, stable disease, and/or functional deterioration with one treatment-related death. The 30-day mortality was 5% in patients who underwent operation. The 5-year survival rate for 120 patients was 21.7%, and it was 43.1% in patients with complete resection. In postoperative patients with stage N0 disease, 5-year survival was 53.3%; if stage N2 or N3 disease was still present, 5-year survival was 33.3%. CONCLUSION Staging and treatment with chemoradiotherapy and complete resection performed in experienced centers achieve acceptable morbidity and mortality.
