Anaplastic lymphoma kinase (ALK) rearrangement in adult renal cell carcinoma with lung metastasis: a case report and literature review

Renal cell carcinoma (RCC) with anaplastic lymphoma kinase (ALK) rearrangement is rare, and the genetic profiles of the tumor have not been elucidated. Here, we report a case with recurrent papillary RCC and lung metastasis after nephrectomy for nearly 7 years. The patient first received sunitinib, whereas the drug toxicity was intolerable. Combined Immunohistology (IHC) and fluorescence in situ hybridization (FISH) revealed the patient has an ALK rearrangement, and the patient then was treated with crizotinib. The patient had good tolerance, and a partial response in the target lesions was achieved. In order to further understand the benefit of crizotinib in ALK-rearranged RCC, the patient was detected with whole exome sequencing (WES) to study her genetic profiles. Compared those of RCC cases without ALK rearrangement (nALK-RCC), the patient and nine RCC cases with ALK rearrangement (ALK-RCC) revealed unique genetic characteristics: 1) The common mutations that occurred in RCC were n.....

How to select the best upfront therapy for metastatic disease? Focus on ALK-rearranged non-small cell lung cancer (NSCLC)

Since then, subsequent generations of ALK inhibitors have demonstrated superior efficacy and better CNS activity compared to crizotinib. Alectinib and brigatinib, both second-generation ALK inhibitors have been compared directly to crizotinib in the first-line setting and has demonstrated improved progression free survival (PFS) and intracranial response. Ceritinib, another second-generation ALK inhibitor has been shown to be superior to chemotherapy in ALK-rearranged disease with good CNS activity. Initial responses to ALK inhibitors are not always durable and resistance can occur as on-target or off-target alterations. Lorlatinib, a third-generation ALK inhibitor, has demonstrated activity in the treatment naïve setting and in resistance to crizotinib and second-generation ALK inhibitors. Lorlatinib has also shown improved PFS in patients harboring EML4-ALK variant 3, which is associated with the development of ALK resistance mutations, specifically G1202R. Another new ALK inhibitor, ensartinib, has demonstrated efficacy in the first-line setting and in alectinib refractory disease. READ ARTICLE

A case report of exceptional clinical response to chemoradiotherapy and tyrosine kinase inhibitors in a patient with EML4-ALK fusion variant 1 non-small cell lung cancer

Herein, we report the case of a non-smoking 36-year-old female patient who was diagnosed with right lung adenocarcinoma in 2005 (cT1N3M0, IIIB) and received definitive chemoradiotherapy. The patient achieved a partial response, and her disease remained under control for 8 years. However, in May 2013, the patient was diagnosed with brain metastasis and underwent subsequent surgical resection, followed by postoperative brain radiotherapy and chemotherapy. Postoperative pathology confirmed ALK gene rearrangement, and next-generation sequencing performed in 2020 identified the EML4-ALK variant as variant 1. After progression-free survival lasting 4 years, new metastatic lesions were found in the patient’s right lung, and she was administered crizotinib for 20 months. Due to a suspicious recurrence in the intracranial surgical margin area, as well as an unbearable gastrointestinal reaction to crizotinib, alectinib was later adopted. At the 7-month follow-up, positron emission tomography/com..... READ ARTICLE

Resistance to anaplastic lymphoma kinase inhibitors: knowing the enemy is half the battle won

The bedrock of resistance to TKI is that, after the diagnosis, we face with a different disease that needs to be re-characterized through tissue or/and liquid biopsies. Understanding molecular pathways driving the resistant phenotype will give us the chance to know what we are dealing with and, rather than choose an empirical approach, will help us to properly define the best targeted treatment for these patients.

Immunotherapy in EGFR-Mutant and ALK-Positive Lung Cancer

Non-small cell lung cancer (NSCLC) is a heterogeneous disease, commonly
defined by genetic alterations in oncogenic drivers. Targeted therapies
have transformed the management of oncogene-driven lung cancers, with
targeted agents now approved in the United States for 7 distinct
molecular alterations. Nonetheless, acquired resistance remains an
ongoing challenge, underscoring the need for alternative therapeutic
approaches. Immune checkpoint inhibitors targeting the programmed cell
death 1 (PD-1) axis have emerged as important therapies in the
management of advanced NSCLC, but the role of these agents in patients
with oncogenic driver mutations remains unclear. Here, we focus on
epidermal growth factor receptor-mutant and anaplastic lymphoma
kinase-rearranged NSCLC as paradigms to explore the role of immune
checkpoint inhibitors in oncogene-driven NSCLC. We provide an overview
of the clinical data examining programmed death ligand 1 (PD-L1)
inhibitor monotherapy, PD-(L)1 inhibitors, and tyrosine kinase inhibitor
combinations, as well as combinations of PD-(L)1 inhibitors and
chemotherapy. READ ARTICLE

Targeted cancer therapy induces APOBEC fuelling the evolution of drug resistance

Targeted therapy directed against EGFR and ALK oncoproteins in lung cancer induced adaptations favoring apolipoprotein B mRNA-editing enzyme, catalytic polypeptide (APOBEC)-mediated genome mutagenesis. In human oncogenic EGFR-driven and ALK-driven lung cancers and preclinical models, EGFR or ALK inhibitor treatment induced the expression and DNA mutagenic activity of APOBEC3B via therapymediated activation of NF-kB signaling. Moreover, targeted therapy also mediated downregulation of certain DNA repair enzymes such as UNG2, which normally counteracts APOBEC-catalyzed DNA deamination events. In mutant EGFR-driven lung cancer mouse models, APOBEC3B was detrimental to tumour initiation and yet advantageous to tumour progression during EGFR targeted therapy, consistent with TRACERx data demonstrating subclonal enrichment of APOBEC-mediated mutagenesis. This study reveals how cancers adapt and drive genetic diversity in response to targeted therapy and identifies APOBEC deaminases as future targets for eliciting more durable clinical benefit to targeted cancer therapy.

Prolonged survival without progression under crizotinib treatment

In recent years, serious changes have been observed in the treatment algorithms of especially lung cancer patients. The start-up phase of treatment planning of metastatic lung adenocarcinoma patients is comprised of driver mutation research. Among the pretreatment options of patients diagnosed with EML4-ALK rearrangement, is crizotinib. The group disgnosed with EML4-ALK rearrangement, composes a little part of metastatic non-small cell lung cancer. In this case presented, I will focus on the start of crizotinib treatment and 53-month follow-up in remission in a patient, who has been operated twice and received cisplatin-based adjuvant chemotherapy twice, and relapsed for the second time as Stage-4.

ALK variants, PD-L1 expression, and their association with outcomes in ALK-positive NSCLC patients

It remains unclear how programmed death-ligand 1 (PD-L1) expression interacts with anaplastic lymphoma kinase (ALK) mutation, its variants, and the outcome of treatment. One hundred and twenty four out of 1255 patients (9.9%) were deemed ALK-positive by the Ventana IHC assay. PD-L1 status and ALK variants were available in 100 and 59 patients, respectively. PD-L1 positive (TPS ≥ 1%) and strong positive (TPS ≥ 50%) rate was 50% and 16%, respectively. A total of 64 variant types were detected in 59 patients. V1 (32.8%) and V3a/b (28.1%) were the most common variants. There was no significant association between ALK variants and the PD-L1 expression. The presence of V3a/b subtype independently predicted a worse overall survival in patients receiving ALK inhibitor(s) (aHR 5.10 [95% CI 1.22–21.25], P = 0.025) and platinum plus pemetrexed (aHR 9.62 [95% CI 1.90–48.80], P = 0.006). While incorporating ALK variants and PD-L1 expression together, patients with non-V3a/b/positive PD-L1 showed a ..... READ ARTICLE

What Is the Standard First-Line Treatment for Advanced Non-Small Cell Lung Cancer?

The initial treatment regimens for advanced non-small cell lung cancer (NSCLC) have drastically evolved over the last 15 years with the rapid development of improved genomic sequencing technologies and the emergence of immune checkpoint inhibitors. Highly active oral kinase inhibitors are now approved for several molecularly defined subsets of NSCLC, including those harboring alterations in the EGFR, ALK, ROS1, BRAF, MET, RET, and NTRK genes, although acquired resistance to these targeted therapies remains a significant clinical challenge. In lung cancers lacking targetable mutations, programmed death 1/programmed death ligand 1 immune checkpoint inhibitors, used alone or in combination with cytotoxic T-lymphocyte-associated protein 4 inhibitors and/or cytotoxic chemotherapy, have led to meaningful improvements in overall survival. With many therapeutic options available to patients, here we review the recommended frontline treatment regimens for advanced NSCLC with and without targetable genomic drivers. READ ARTICLE

PROTACs: A novel strategy for cancer therapy

Chemotherapeutic strategy has been widely used for treating malignance by targeting irregular expressed or mutant proteins with small molecular inhibitors (SMIs) or monoclonal antibodies (mAbs). However, most intracellular proteins lack of active sites or antigens where SMIs or mAbs bind with, and are called as non-druggable targets for a long time. From the first year of this century, PROteolysis-TArgeting Chimeras (PROTACs) has emerged to be a promising approach for proteins, including those non-druggable ones, such as transcriptional factors and scaffold proteins. The first generation of peptide-based PROTACs adopts β-TrCP and VHL as E3 ligases, but the cellular permeability and chemical stability issues restrict their clinical application. The second generation of small molecule-based PROTACs adopts MDM2, VHL, IAPs and Cereblon as E3 ligases have been tensely studied. To date, the targets of PROTACs including those overexpressed oncogenic proteins such as ER, AR and BRDs, disease-r..... READ ARTICLE

Functional coding/non-coding variants in EGFR, ROS1 and ALK genes and their role in liquid biopsy as a personalized therapy

Personalized medicine holds promise to tailor the treatment options for patients’ unique genetic make-up, behavioral and environmental background. Liquid biopsy is non-invasive technique and precise diagnosis and treatment approach. Significantly, NGS technologies have revolutionized the genomic medicine by novel identifying SNPs, indel mutations in both coding and non-coding regions and also a promising technology to accelerate the early detection and finding new biomarkers for diagnosis and treatment. The number of the bioinformatics tools have been rapidly increasing with the aim of learning more about the detected mutations either they have a pathogenic role or not. EGFR, ROS1 and ALK genes are members of the RTK family. Until now, mutations within these genes have been associated with many cancers and involved in resistance formation to TKIs. This review article summarized the findings about the mostly investigated variations in EGFR, ROS1 and ALK genes and their potential role in..... READ ARTICLE

Clinicopathological features and immunohistochemical utility of NTRK-, ALK-, and ROS1-rearranged papillary thyroid carcinomas and anaplastic thyroid carcinomas

NTRK1/3, ALK, and ROS1 translocations have been reported in a minor subset of papillary thyroid carcinomas (PTCs). We aimed to elucidate the prevalence and clinicopathological characteristics of these gene rearrangements and the utility of immunohistochemistry (IHC) in PTC and anaplastic thyroid carcinoma (ATC). We screened nonradiation-exposed cases of 307 PTCs and 16 ATCs by IHC for pan-Trk, ALK, and ROS1, followed by fluorescence in situ hybridization (FISH). In the PTC group, IHC for pan-Trk, ALK, and ROS1 was positive in 18 cases (5.9%), 1 case (0.3%), and 12 cases (3.9%), respectively. Among the pan-Trk IHC–positive cases (n = 18), 2 cases (11.1%; 0.7% of all PTCs) had NTRK1 or NTRK3 gene rearrangement with conventional PTC histology. The ALK IHC–positive case (n = 1) was the follicular variant of PTC with consistent ALK gene rearrangement. ROS1 gene rearrangement was not detectable in the ROS1 IHC–positive PTCs (0/12) by FISH. Most (approximately 70%) of the pan-Trk or ROS1 IHC–..... READ ARTICLE
