Lung squamous cell carcinoma with rare epidermal growth factor receptor mutation G719X: a case report and literature review. ANNALS OF TRANSLATIONAL MEDICINE 2021; 9:1805.

Abstract
Asians who develop non-small cell lung cancer (NSCLC) have a chance of approximately 50% of harboring the epidermal growth factor receptor (EGFR) mutation. The G719X mutation in EGFR has 3 subtypes (i.e., G719A, G719C, or G719S), all of them being classified as uncommon EGFR mutations. The EGFR mutation G719X is most often associated with lung adenocarcinoma. Conversely, its occurrence in lung squamous cell carcinoma is rare. Its response to tyrosine kinase inhibitor (TKI) treatment remains unknown. A 50-year-old Asian male with no smoking history was admitted to our hospital (Affiliated Hospital of Qingdao University) with an irritating dry cough and 1 month of progressive dyspnea. The patient was diagnosed with lung squamous cell carcinoma (cT4N3M0, stage IIIC). Lung biopsy revealed the presence of EFGR G719X mutation. The patient received a tracheobronchial stent, targeted therapy, chemotherapy, seed implantation and radiotherapy, and survived for 25.4 months following diagnosis. It is crucial that gene mutation analysis is performed in non-smoking male squamous cell carcinoma patients. Compared to lung adenocarcinoma patients with rare G719X mutation, this lung squamous cell carcinoma patient with G719X-mutant tumor had a higher sensitivity to 2nd-generation EGFR-TKI treatment, but similar progression-free survival. Importantly, the patient clearly benefited from the used comprehensive treatment plan. This article seeks to shed light on the treatment of lung squamous cell carcinoma patients with the uncommon EGFR G719X mutation.

Abstract
Avoidance of apoptosis induced by anticancer drugs is an essential factor of carcinogenesis and a hallmark of resistance to cancer therapy. Human telomerase reverse transcriptase receptor (hTERTR) is a potential anti-cancer agent for inhibiting tumor growth. Family with sequence similarity 96 member A (FAM96A) is a ubiquitous, conserved protein and possesses apoptosome-activating and pro-apoptotic tumor suppressor potential in hepatocellular carcinoma (HCC). In the present study, hTERTR and FAM96A were identified as efficient anti-cancer agents for activating apoptosomes and reducing tumor growth. The potential tumor suppressor function of combination treatment with hTERTR and FAM96A in HCC was also investigated. hTERTR and FAM96A proteins were expressed by genetic engineering and their anti-cancer function was explored in vitro and in vivo. Effects of hTERTR and FAM96A on improvement of apoptotic sensitivity and inhibition of migration and invasion were examined in cancer cells and in a mouse model. The present results demonstrated that the therapeutic effects of hTERTR and FAM96A were effective for inhibiting tumor growth and inducing apoptosis of HCC cells in H22-bearing nude mice compared with single agent treatment. hTERTR and FAM96A were found to bind with apoptotic protease activating factor 1 and human telomerase reverse transcriptase, which enhanced the apoptosis of tumor cells and apoptosis sensitivity. In addition, hTERTR and FAM96A therapy enhanced cytotoxic effects by cytotoxic T lymphocyte responses, interferon-γ release, T lymphocytes infiltration and apoptosis on tumor cells. Furthermore, hTERTR and FAM96A protein inhibited tumor growth in HCC mice. In conclusion, the present findings suggested that combination therapy with hTERTR and FAM96A may serve as novel tumor suppressor agents.

Abstract
Lenvatinib is an oral, multi-targeted tyrosine kinase inhibitor of vascular endothelial growth factor receptors 1-3, fibroblast growth factor receptors 1-4, platelet-derived growth factor receptor β, RET and KIT. Cellular immunotherapy has the potential to be a highly targeted treatment, with low toxicity to normal tissues and a high capacity to eradicate tumor tissue. The present study assessed the safety, maximum tolerated dose (MTD) and preliminary antitumor activity of lenvatinib and cellular immunotherapy in a murine model of renal cell carcinoma (RCC). The present study used a therapeutic dose of 0.12 mg lenvatinib and/or 104 rat uterine cancer adenocarcinoma (RuCa)-sensitized lymphocytes administered once daily continuously in 7-day cycles. Tumor regression was observed in mice with RCC following treatment with lenvatinib and 104 RuCa-sensitized lymphocytes. MTD was established as once daily administration of 0.18 mg lenvatinib and 106 RuCa-sensitized lymphocytes. The most common treatment-related adverse effects observed were fatigue (40%), mucosal inflammation (30%), proteinuria, diarrhea, vomiting, hypertension and nausea (all 40%). Combination therapy using lenvatinib and cellular immunotherapy enhanced the antitumor effect induced by single treatments and prolonged the survival of mice with RCC compared with either of the single treatments. Treatment with lenvatinib (0.12 mg) combined with 104 RuCa-sensitized lymphocytes was associated with manageable toxicity consistent with individual agents. Further evaluation of this combination therapy in mice with advanced RCC is required. In conclusion, cellular immunotherapy and oncolytic therapy for cancer may be improved by the synergistic effects of lenvatinib and sensitized lymphocytes. In the present study, the inherent antineoplastic and immune stimulatory properties of the two agents were enhanced when used in combination, which may provide a basis for clinical treatment of patients with RCC.

Abstract
The abilities to escape apoptosis induced by anticancer drugs are an essential factor of carcinogenesis and a hallmark of resistance to cancer therapy. In this study, we identified hTERTR-FAM96A (human telomerase reverse transcriptase–family with sequence similarity 96 member A) as a new efficient agent for apoptosome-activating and anti-tumor protein and investigated the potential tumor suppressor function in hepatocellular carcinoma. The hTERTR-FAM96A fusion protein was constructed by genetic engineering and its anticancer function of hTERTR-FAM96A was explored in vitro and in vivo by investigating the possible preclinical outcomes. Effects of hTERTR-FAM96A on improvement of apoptotic sensitivity and inhibition of migration and invasion were examined in cancer cells and tumors. Our results showed that the therapeutic effects of hTERTR-FAM96A were highly effective for inhibiting tumor growth and inducing apoptosis of hepatocellular carcinoma cells in H22-bearing nude mice. The hTERTR-FAM96A fusion protein could specifically bind with Apaf-1 and hTERT, which further induced apoptosis of hepatocellular carcinoma cells and improved apoptosis sensitivity. Our results indicated that hTERTR-FAM96A treatment enhanced cytotoxic effects by upregulation of cytotoxic T lymphocyte responses, interferon-γ release, and T lymphocyte infiltration. In addition, hTERTR-FAM96A led to tumor-specific immunologic cytotoxicity through increasing apoptotic body on hepatocellular tumors. Furthermore, hTERTR-FAM96A dramatically inhibited tumor growth, reduced death rate, and prolonged mice survival in hepatocellular carcinoma mice derived from three independent hepatocellular carcinoma mice cohorts compared to control groups. In summary, our data suggest that hTERTR-FAM96A may serve as an efficient anti-tumor agent for the treatment of hepatocellular carcinoma.

Abstract
Lung cancer is the most common cancer diagnosed in the UK. Outcomes for patients with this disease remain poor and new strategies to treat this disease require investigation. One potential option is to combine novel agents with radiotherapy in clinical studies. Here we discuss some of the important issues to consider when combining novel agents with radiotherapy, together with potential solutions as discussed at a recent Clinical Translational Radiotherapy Group (CTRad) workshop.

Abstract
Radiotherapy has had important role in the palliation of NSCLC. Randomized trials tend to suggest that, in general, short regimens give similar palliation and toxicity compared to longer regimens. The benefit of combining chemotherapy to radiosensitize the palliative radiation treatment is an open question, but so far it has not been proved to be very useful in NSCLC. The addition of molecular targeted drugs to radiotherapy outside of approved regimens or clinical trials warrants careful consideration for every single case and probably should not be used as a routine management. Stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT) are modern techniques being used each time more frequently in the treatment of single or oligometastases. In general, they offer good tumor control with little toxicity (with a more expensive cost) compared to the traditionally fractionated radiotherapy regimens.

A phase II trial of erlotinib as maintenance treatment after concurrent chemoradiotherapy in stage III non-small-cell lung cancer (NSCLC): a Galician Lung Cancer Group (GGCP) study. Cancer Chemother Pharmacol 2013; 73:451-7. [PMID: 24352251 DOI: 10.1007/s00280-013-2370-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2013] [Accepted: 12/11/2013] [Indexed: 12/28/2022]
Abstract
PURPOSE This single arm, phase II study aims to evaluate the role of epidermal growth factor receptor-tyrosine-kinase inhibitor erlotinib as maintenance therapy following concurrent chemoradiotherapy (cCRT) in unresectable locally advanced non-small-cell lung cancer (NSCLC). METHODS Patients with unresectable stage IIIA o dry IIIB NSCLC with no evidence of tumor progression after receiving a standard cCRT regimen with curative intent were included. Oral erlotinib 150 mg/day was administered within 4-6 weeks after the end of the cCRT for a maximum of 6 months if no disease progression or intolerable toxicity occurred. Primary end point was the progression-free rate (PFR) at 6 months. Secondary end points included time to progression (TTP) and overall survival (OS). RESULTS Sixty-six patients were enrolled and received maintenance treatment with erlotinib [average: 4.5 months (95 % CI 4.0-5.0)]. PFR at 6 months was 63.5 % (41/66). With a median follow-up of 22.7 months (95 % CI 13.5-37.1), the median TTP was 9.9 months (95 % CI 6.2-12.1), and the median OS was 24.0 months (95 % CI 17.3-48.6). Most common adverse events (AEs) related to erlotinib were rash (78.8 %; 16.7 % grade 3), diarrhea (28.8 %; 1.5 % grade 3), fatigue (15.2 %; 1.5 % grade 3), anorexia (7.6 %; 1.5 % grade 3) and vomiting (4.6 %; none grade 3). Five patients (7.6 %) were withdrawn due to AEs. CONCLUSIONS Erlotinib as maintenance therapy is an active treatment after cCRT in unselected patients with stage III NSCLC, reaching a 6-month PFR of 63.5 % and a median OS of 24 months. The safety profile of maintenance erlotinib was as expected and manageable.

Abstract
Lung cancer is the leading cause of cancer-related death. Between 80-85% of lung cancers are non-small cell lung carcinomas. One third of the patients are diagnosed with locally advanced stage. In this condition, concomitant radio-chemotherapy is the standard treatment for patients with good performance status. Despite important improvements in the last years, non-small cell lung carcinoma prognosis remains poor, with high rates of both local recurrences and metastases. The heterogeneity of molecular characteristics of non-small cell lung carcinoma cells and a better knowledge of potential targets offer promising developments for new pharmacologic agents. Hereafter we will review the currently most studied pathways and the most promising ones for the treatment of locally advanced unresectable non-small cell lung carcinoma. Two of the most attractive pathways where new agents have been developed and assessed in combination with thoracic radiotherapy or radiochemotherapy are the EGFR pathway (either with the use of monoclonal antibodies or tyrosine kinase inhibitors) and the angiogenesis inhibition. The development of targeted agents could lead to individualized therapeutic combinations taking into account the intrinsic characteristics of tumor cells. Pharmacological modulation of tumour cells radiosensitivity by targeted therapies is only starting, but yet offers promising perspectives.
