Screening for Epidermal Growth Factor Receptor Mutations in Lung Cancer
2009
Lung cancers with a mutation in the
EGFR
gene have heightened sensitivity to tyrosine kinase inhibitors. Asian patients have been the most intensively studied population for such mutations and for responsiveness to tyrosine kinase inhibitors. This study shows that large-scale screening for
EGFR
mutations in a European population is feasible and can influence decisions about treatment of advanced lung cancer.

Molecular-profiling studies indicate that activating mutations in the epidermal growth factor receptor (
EGFR
),
PI3K
,
BRAF,
and
K-ras
genes are generally nonoverlapping and identifiable in approximately 40% of non–small-cell lung cancers. These mutations, plus others that contribute to tumor progression (“driver” mutations), can be found in almost half of all non–small-cell lung cancers.

The two proto-oncogenes that are most commonly mutated in pulmonary adenocarcinomas are
K-ras
and
EGFR
. Nearly 90% of lung-cancer–specific
EGFR
mutations comprise a leucine-to-arginine substitution at position 858 (L858R) and deletion mutants in exon 19 that affect the conserved sequence LREA (delE746-A750).

Antineoplastic Agents - adverse effects
2009
Several studies have shown the efficacy, tolerability, and ease of administration of pemetrexed—an antifolate antineoplastic agent—in patients with advanced non-small-cell lung cancer. We assessed pemetrexed as maintenance therapy in patients with this disease.
This randomised double-blind study was undertaken in 83 centres in 20 countries. 663 patients with stage IIIB or IV disease who had not progressed on four cycles of platinum-based chemotherapy were randomly assigned (2:1 ratio) to receive pemetrexed (500 mg/m
2, day 1) plus best supportive care (n=441) or placebo plus best supportive care (n=222) in 21-day cycles until disease progression. Treatment was randomised with the Simon and Pocock minimisation method. Patients and investigators were masked to treatment. All patients received vitamin B
12, folic acid, and dexamethasone. The primary endpoint of progression-free survival and the secondary endpoint of overall survival were analysed by intention to treat. This study is registered with
ClinicalTrials.gov, number
NCT00102804.
All randomly assigned participants were analysed. Pemetrexed significantly improved progression-free survival (4·3 months [95% CI 4·1–4·7]
vs 2·6 months [1·7–2·8]; hazard ratio [HR] 0·50, 95% CI 0·42–0·61, p<0·0001) and overall survival (13·4 months [11·9–15·9]
vs 10·6 months [8·7–12·0]; HR 0·79, 0·65–0·95, p=0·012) compared with placebo. Treatment discontinuations due to drug-related toxic effects were higher in the pemetrexed group than in the placebo group (21 [5%]
vs three [1%]). Drug-related grade three or higher toxic effects were higher with pemetrexed than with placebo (70 [16%]
vs nine [4%]; p<0·0001), specifically fatigue (22 [5%]
vs one [1%], p=0·001) and neutropenia (13 [3%]
vs 0, p=0·006). No pemetrexed-related deaths occurred. Relatively fewer patients in the pemetrexed group than in the placebo group received systemic post-discontinuation therapy (227 [51%]
vs 149 [67%]; p=0·0001).
Maintenance therapy with pemetrexed is well tolerated and offers improved progression-free and overall survival compared with placebo in patients with advanced non-small-cell lung cancer.

Background
The cancer vaccine Vx-001, which targets the universal tumour antigen TElomerase Reverse Transcriptase (TERT), can mount specific Vx-001/TERT
572
CD8 + cytotoxic T cells; this immune response is associated with improved overall survival (OS) in patients with advanced/metastatic non-small cell lung cancer (NSCLC).
Methods
A randomised, double blind, phase 2b trial, in HLA-A*201-positive patients with metastatic, TERT-expressing NSCLC, who did not progress after first-line platinum-based chemotherapy were randomised to receive either Vx-001 or placebo. The primary endpoint of the trial was OS.
Results
Two hundred and twenty-one patients were randomised and 190 (101 and 89 patients in the placebo and the Vx-001 arm, respectively) were analysed for efficacy. There was not treatment-related toxicity >grade 2. The study did not meet its primary endpoint (median OS 11.3 and 14.3 months for the placebo and the Vx-001, respectively;
p
= 0.86) whereas the median Time to Treatment Failure (TTF) was 3.5 and 3.6 months, respectively. Disease control for >6months was observed in 30 (33.7%) and 26 (25.7%) patients treated with Vx-001 and placebo, respectively. There was no documented objective CR or PR. Long lasting TERT-specific immune response was observed in 29.2% of vaccinated patients who experienced a significantly longer OS compared to non-responders (21.3 and 13.4 months, respectively;
p
= 0.004).
Conclusion
Vx-001 could induce specific CD8
+
immune response but failed to meet its primary endpoint. Subsequent studies have to be focused on the identification and treatment of subgroups of patients able to mount an effective immunological response to Vx-001.

BackgroundBevacizumab is an approved treatment after primary debulking surgery for ovarian cancer. However, there is limited information on bevacizumab added to neoadjuvant chemotherapy before interval debulking surgery.ObjectiveTo evaluate neoadjuvant bevacizumab in a randomized phase II trial.MethodsPatients with newly diagnosed stage III/IV high-grade serous/endometrioid ovarian cancer were randomized to receive four cycles of neoadjuvant chemotherapy with or without ≥3 cycles of bevacizumab 15 mg/kg every 3 weeks. After interval debulking surgery, all patients received post-operative chemotherapy (three cycles) and bevacizumab for 15 months. The primary end point was complete macroscopic response rate at interval debulking surgery.ResultsOf 68 patients randomized, 64 completed four neoadjuvant cycles; 22 of 33 (67%) in the chemotherapy-alone arm and 31 of 35 (89%) in the bevacizumab arm (p=0.029) underwent surgery. The complete macroscopic response rate did not differ between treatment arms in either the intention-to-treat population of 68 patients (6.1% vs 5.7%, respectively; p=0.25) or the 55 patients who underwent surgery (8.3% vs 6.5%; p=1.00). There was no difference in complete cytoreduction rate or progression-free survival between the treatment arms. During neoadjuvant therapy, grade ≥3 adverse events were more common with chemotherapy alone than with bevacizumab (61% vs 29%, respectively; p=0.008). Intestinal (sub)occlusion, fatigue/asthenia, abdominal infection, and thrombocytopenia were less frequent with bevacizumab. The incidence of grade ≥3 adverse events was 9% in the control arm versus 16% in the experimental arm in the month after surgery.ConclusionsAdding three to four pre-operative cycles of bevacizumab to neoadjuvant chemotherapy for unresectable disease did not improve the complete macroscopic response rate or surgical outcome, but improved surgical operability without increasing toxicity. These results support the early integration of bevacizumab in carefully selected high-risk patients requiring neoadjuvant chemotherapy for initially unresectable ovarian cancer.

INOVATYON/ ENGOT-ov5 study: Randomized phase III international study comparing trabectedin/pegylated liposomal doxorubicin (PLD) followed by platinum at progression vs carboplatin/PLD in patients with recurrent ovarian cancer progressing within 6-12 months after last platinum line
2023
BackgroundThis trial investigated the hypothesis that the treatment with trabectedin/PLD (TP) to extend the platinum-free interval (TFIp) can improve overall survival (OS) in patients with recurrent ovarian cancer (OC).MethodsPatients with OC (up to two previous platinum-based lines), with a TFIp of 6–12 months, were randomised to receive carboplatin/PLD (CP) or TP followed by platinum therapy at relapse. The primary endpoint was OS (HR: 0.75).ResultsThe study enrolled 617 patients. The median TFIp was 8.3 months and 30.3% of patients had received two previous platinum lines. 74% and 73.9% of patients, respectively, received a subsequent therapy (ST) in the CP and TP arm; in the latter TP arm 87.2% of ST was platinum-based, as per protocol. The median OS was 21.4 for CP and 21.9 months for TP (HR 1.13; 95% CI: 0.94–1.35; p = 0.197). Grade 3–5 adverse reactions occurred in 37.1% of patients in the CP arm and 69.7% of patients in the TP arm, and the most frequent were neutropenia (22.8% CP, 39.5% TP), gastrointestinal (7.1% CP, 17.4% TP), hepatic (0.7% CP, 19.1% TP).ConclusionsThis study did not meet the primary endpoint. CP combination remains the standard for patients with recurrent OC and a 6–12 months TFIp; TP is an effective treatment in patients suffering from persistent platinum toxicities.Clinical trial registrationClinicalTrials.gov, number NCT01379989.

2023
Background
Granulosa cell ovarian tumor (GCT) is characterized by a pathognomonic mutation in the FOXL2 gene (402 C > G) that leads to an overactivation of steroidogenesis. CYP17 is a key enzyme in such process and can be inhibited by ketoconazole.
Methods
We designed a phase II clinical trial to assess the efficacy of ketoconazole in advanced GCT and conducted several in vitro studies to support the clinical findings.
Results
From October 1st 2012 to January 31st 2014, six evaluable patients were recruited in ten hospitals of the Spanish Group for Transversal Oncology and Research in Orphan and Infrequent Tumors” (GETTHI). FOXL2 (402C > G) mutation was confirmed in three; two cases were wild type and it could not be assessed in one. No objective response by RECIST was observed, but five cases achieved stable disease longer than 12 months. Median progression-free survival was 14.06 months (CI 95% 5.43–22.69) for the whole study population (3.38 and 13.47 months for wild-type cases and 14.06, 20.67 and 26.51 for those with confirmed FOXL2 mutation). Median overall survival was 22·99 months (CI 95% 8.99–36.99). In vitro assays confirmed the activity of ketoconazole in this tumor and suggested potential synergisms with other hormone therapies.
Conclusion
Ketoconazole has shown activity in advanced GCT in clinical and in vitro studies. Based on these data, an orphan designation was granted by the European Medicines Agency for ketoconazole in GCT (EU/3/17/1857).

Erlotinib has been shown to improve progression-free survival compared with chemotherapy when given as first-line treatment for Asian patients with non-small-cell lung cancer (NSCLC) with activating EGFR mutations. We aimed to assess the safety and efficacy of erlotinib compared with standard chemotherapy for first-line treatment of European patients with advanced EGFR-mutation positive NSCLC. We undertook the open-label, randomised phase 3 EURTAC trial at 42 hospitals in France, Italy, and Spain. Eligible participants were adults (> 18 years) with NSCLC and EGFR mutations (exon 19 deletion or L858R mutation in exon 21) with no history of chemotherapy for metastatic disease (neoadjuvant or adjuvant chemotherapy ending ≥ 6 months before study entry was allowed). We randomly allocated participants (1:1) according to a computer-generated allocation schedule to receive oral erlotinib 150 mg per day or 3 week cycles of standard intravenous chemotherapy of cisplatin 75 mg/m(2) on day 1 plus docetaxel (75 mg/m(2) on day 1) or gemcitabine (1250 mg/m(2) on days 1 and 8). Carboplatin (AUC 6 with docetaxel 75 mg/m(2) or AUC 5 with gemcitabine 1000 mg/m(2)) was allowed in patients unable to have cisplatin. Patients were stratified by EGFR mutation type and Eastern Cooperative Oncology Group performance status (0 vs 1 vs 2). The primary endpoint was progression-free survival (PFS) in the intention-to-treat population. We assessed safety in all patients who received study drug (≥ 1 dose). This study is registered with ClinicalTrials.gov, number NCT00446225. Between Feb 15, 2007, and Jan 4, 2011, 174 patients with EGFR mutations were enrolled. One patient received treatment before randomisation and was thus withdrawn from the study; of the remaining patients, 86 were randomly assigned to receive erlotinib and 87 to receive standard chemotherapy. The preplanned interim analysis showed that the study met its primary endpoint; enrolment was halted, and full evaluation of the results was recommended. At data cutoff (Jan 26, 2011), median PFS was 9·7 months (95% CI 8·4-12·3) in the erlotinib group, compared with 5·2 months (4·5-5·8) in the standard chemotherapy group (hazard ratio 0·37, 95% CI 0·25-0·54; p < 0·0001). Main grade 3 or 4 toxicities were rash (11 [13%] of 84 patients given erlotinib vs none of 82 patients in the chemotherapy group), neutropenia (none vs 18 [22%]), anaemia (one [1%] vs three [4%]), and increased amino-transferase concentrations (two [2%] vs 0). Five (6%) patients on erlotinib had treatment-related severe adverse events compared with 16 patients (20%) on chemotherapy. One patient in the erlotinib group and two in the standard chemotherapy group died from treatment-related causes. Our findings strengthen the rationale for routine baseline tissue-based assessment of EGFR mutations in patients with NSCLC and for treatment of mutation-positive patients with EGFR tyrosine-kinase inhibitors.

Aboriginal Australians
2017
Aboriginal Australians represent one of the longest continuous cultural complexes known. Archaeological evidence indicates that Australia and New Guinea were initially settled approximately 50 thousand years ago (ka); however, little is known about the processes underlying the enormous linguistic and phenotypic diversity within Australia. Here we report 111 mitochondrial genomes (mitogenomes) from historical Aboriginal Australian hair samples, whose origins enable us to reconstruct Australian phylogeographic history before European settlement. Marked geographic patterns and deep splits across the major mitochondrial haplogroups imply that the settlement of Australia comprised a single, rapid migration along the east and west coasts that reached southern Australia by 49–45 ka. After continent-wide colonization, strong regional patterns developed and these have survived despite substantial climatic and cultural change during the late Pleistocene and Holocene epochs. Remarkably, we find evidence for the continuous presence of populations in discrete geographic areas dating back to around 50 ka, in agreement with the notable Aboriginal Australian cultural attachment to their country.
Analysis of Aboriginal Australian mitochondrial genomes shows geographic patterns and deep splits across the major haplogroups that indicate a single, rapid migration along the coasts around 49–45 ka, followed by longstanding persistence in discrete geographic areas.
The first Aboriginal walkabout
Aboriginal Australians preserve one of the longest continuous cultural complexes known, with archaeological evidence dating initial settlement of the continent to around 50,000 years ago. Alan Cooper and colleagues have charted the subsequent progress of humanity in and around the continent in the form of 111 mitochondrial genomes from preserved hair samples. The results show that, from landfall in the north of Australia, people spread rapidly around the east and west coasts, meeting in southern Australia as early as 49,000 years ago. Strong regional patterns of mitochondrial DNA variation suggest that when people stopped moving they stayed put, putting down cultural roots that have weathered 50,000 years of significant cultural and climatic change.

The COVID-19 pandemic has caused remarkable psychological overwhelming and an increase in stressors that may trigger suicidal behaviors. However, its impact on the rate of suicidal behaviors has been poorly reported. We conducted a population-based retrospective analysis of all suicidal behaviors attended in healthcare centers of Catalonia (northeast Spain; 7.5 million inhabitants) between January 2017 and June 2022 (secondary use of data routinely reported to central suicide and diagnosis registries). We retrieved data from this period, including an assessment of suicide risk and individuals’ socioeconomic as well as clinical characteristics. Data were summarized yearly and for the periods before and after the onset of the COVID-19 pandemic in Spain in March 2020. The analysis included 26,458 episodes of suicidal behavior (21,920 individuals); of these, 16,414 (62.0%) were suicide attempts. The monthly moving average ranged between 300 and 400 episodes until July 2020, and progressively increased to over 600 episodes monthly. In the postpandemic period, suicidal ideation increased at the expense of suicidal attempts. Cases showed a lower suicide risk; the percentage of females and younger individuals increased, whereas the prevalence of classical risk factors, such as living alone, lacking a family network, and a history of psychiatric diagnosis, decreased. In summary, suicidal behaviors have increased during the COVID-19 pandemic, with more episodes of suicidal ideation without attempts in addition to younger and lower risk profiles.
