Pang Fuwan Uses Yao Medicine to Observe the Therapeutic Effects on the Physical and Mental Symptoms of Patients with Advanced Non-Small Cell Lung Cancer

Objective: Investigate the efficacy and safety of Yao Medicine in the treatment of advanced non-small-cell lung carcinoma, and explore the best therapeutic measure for clinical benefit. Methods: From July 2020 to July 2022, 84 patients with advanced non-small-cell lung carcinoma were selected and randomly divided into the Observation Group and control group, and the control group was treated with routine Western medicine, with 42 cases in each group. The activity of daily living (ADL) was assessed before and after treatment, meanwhile, the self-rating depression scale (SDS) and self-rating anxiety SAS (SAS) were used to assess the improvement of a bad mood, and quality of life SF-36 was used to assess the quality of life, to judge the efficacy and safety. Results: The effective rate of observation group was 91.67%. The effective rate of the control group was 76.19%. The effective rate of the observation group was significantly higher than that of the control group (P 0.05). There were no significant differences in the scores of SDS, SAS and quality of life between the two groups before treatment (P > 0.05), and after treatment, the scores of SDS, SAS and quality of life in the two groups were compared with those in the control group (P > 0.05), the scores of VAS, SDS and SAS decreased significantly, while ESCV, angle of straight leg elevation, ADL, physiological score, emotional score, social score and health status score increased significantly, the difference was statistically significant (P 0.05). Conclusion: Yao Medicine can improve the psychosomatic symptoms of patients with advanced non-small-cell lung carcinoma better, with better efficacy and higher safety.

Synchronous multiple lung cancers with hilar lymph node metastasis of small cell carcinoma:A case report

BACKGROUND Synchronous multiple lung cancers are rare and refer to the simultaneous presence of two or more primary lung tumors,which present significant challenges in terms of diagnosis and treatment.CASE SUMMARY We report a case of multiple synchronous lung cancers with hilar lymph node metastasis of small cell carcinoma of unknown origin in a 73-year-old man.Transbronchial lung biopsy revealed squamous cell carcinoma.Although enlargement of lymph node 12u was detected,no distant metastases were observed.The patient was preoperatively diagnosed with T1cN0M0 and underwent thoracoscopic right upper lobectomy with nodal dissection(ND2a).Based on histopathological findings,the primary lesion was squamous cell carcinoma.A microinvasive adenocarcinoma was also observed on the cranial side of the primary lesion.Tumors were detected in two resected lymph nodes(#12u and#11s).Both tumors were pathologically diagnosed as small cell carcinomas.The primary lesion of the small cell carcinoma could not be identified even by whole-body imaging;however,chemotherapy was initiated for hilar lymph node metastasis of the small cell carcinoma of unknown origin.CONCLUSION Multiple synchronous lung cancers can be accompanied by hilar lymph node metastasis of small cell carcinomas of unknown origin.

Progress in diagnosis and treatment of small cell lung cancer with integrated traditional Chinese and Western medicine

Lung cancer is one of the most common major diseases that seriously threaten human health,lung cancer includes small cell lung cancer(SCLC)and non-small cell lung cancer(NSCLC).Although patients with SCLC account for about 20%of the total number of patients with lung cancer,the mortality rate is much higher than that of patients with NSCLC.Integrated traditional Chinese and Western medicine has obvious advantages in the treatment of patients with SCLC.According to the relevant literature reports on the treatment of SCLC in recent years,this article will summarize the research progress of integrated traditional Chinese and western medicine in the treatmentof SCLC from the aspects of traditional Chinese medicine(TCM)combined with surgery,chemotherapy,radiotherapy,and molecular targeted therapy.

Review of the treatment of metastatic non small cell lung carcinoma:A practical approach

In recent years,as we have a better knowledge and understanding of the biology of non small cell lung carcinoma(NSCLC),which leads us to targeting biomarkers driving the NSCLC carcinogenesis and metastatic potential,we now have an increased number of options to offer our patients with NSCLC.We also realize the importance of distinguishing squamous and non squamous histology to guide our treatment decisions of NSCLC.The palliative care concomitant with therapies from the very start of the treatment also showed an impact on survival.This review examines the treatment options in all lines of therapy for metastatic NSCLC that have been approved in Canada,the United States,or Europe.

Relevance of EGFR gene mutation with pathological features and prognosis in patients with non-small-cell lung carcinoma

Objective:To study the relevance of EGFR gene mutation with pathological features and prognosis in patients with non-small-cell lung carcinoma.Methods:A total of 297 patients from July 2009 to May 2013 were chosen as objects.EGFR gene mutation were detected with fluorescence quantitative PCR.Relevance of EGFR gene mutation with clinical and pathological features was analyzed,and the prognosis of EGFR- mutant-patients and that of EGFR- wide type-patients was compared.Results:In 297 patients.136(45.79%) showed EGFR gene mutation.EGFR gene mutation had no significant relevance with age.gender,smoking history,family history of cancer and clinical stage(P>0.05);there was significant relevance between EGFR gene mutation and blood type,pathologic types,differentiation and diameter of cancer(P<0.05).The difference between prognosis of EGFR- mutant-patients and that of EGFR- wide type-patients was statistical significance(P<0.05).Conclusions:EGFR gene mutation has significant relevance with pathological features,the prognosis of EGFRmutant-paticnts is better than that of EGFR- wide type-patients.

Inhibitory Effect of MiR-449b on Cancer Cell Growth and Invasion through LGR4 in Non-Small-Cell Lung Carcinoma

Non-small-cell lung carcinoma （NSCLC） is one of the most frequently diagnosed malignancies worldwide. Previous studies have shown that microRNA-449b （miR-449b） functions as a tumor suppressor in many cancers. However, the role of miR- 449b in NSCLC is still unknown. In the present study, miR-449b was significantly down- regulated in NSCLC samples and cell lines. Bioinformatics analysis revealed that 3＇-UTR region of leucine rich repeat containing G protein-coupled receptor 4 （LGR4） mRNA had putative complementary sequences to miR-449b, which was further confirmed by the luciferase assay. Western blotting showed that restoration of miR-449b in NSCLC cells decreased the expression of LGR4. Interestingly, over-expression of miR-449b inhibited growth and invasion of NSCLC cells in vitro. Furthermore, ectopic expression of LGR4 reversed miR-449b-suppressed proliferation and invasion of NSCLC cells. Therefore, the data of the present study demonstrate that miR-449b inhibits tumor cell growth and invasion by targeting LGR4 in NSCLC.

Case Report:Breast metastasis from small cell lung carcinoma

Breast metastases from extramammary neoplasms are very rare. We presented a 66 year-old female with metastasis of small cell lung carcinoma to the breast. She presented with consolidation over the left upper lobe of her lung undetermined after endobronchial or video-assisted thoracoscopic surgery (VATS) biopsy,and this was treated effectively after antibiotic therapy at initial stage. The left breast lumps were noted 4 months later,and she underwent a modified radical mastectomy under the im-pression of primary breast carcinoma. However,the subsequent chest imaging revealed re-growing mass over the left mediastinum and hilum,and cells with the same morphological and staining features were found from specimens of transbronchial brushing and biopsy. An accurate diagnosis to distinguish a primary breast carcinoma from metastatic one is very important because the therapeutic planning and the outcome between them are different.

Glabridin and Anti-Non-Muscle Myosin IIA Therapy Disrupts Non-Small Cell Lung Carcinoma Motility

Lung cancer is the leading cause of cancer related death in the United States killing over 130,000 people each year. While a combination of chemo and radiation therapy may be effective, surgery is still required for many patients. Without surgery, the disease may progress and lead to metastases. We sought to determine if treatment with anti-non-muscle myosin IIA antibody would inhibit movement of the cells in the presence and absence of glabridin (an isoflavonoid compound shown to inhibit cell migration by inhibiting myosin). We compared inhibition by glabridin to that of an anti-non-muscle myosin IIA antibody and a combination therapy of both at 12 and 24 hours post wound creation. Cells that took up the anti-non-muscle myosin IIA antibody were greatly inhibited in motility and exhibited no significant change in wound healing. Glabridin treatment resulted in a dramatic increase in wound size within 12 hours and regeneration within 24 hours. The greatest decrease in motility was observed in cells treated with the combination of both glabridin and anti-non-muscle myosin IIA antibody. By 24 hrs, cell migration had halted due to death of the cells resulting from this combination. Further testing needs to be done to determine a safe mode of delivery of the combination therapy to ensure only local distribution. Controlled release drug delivery depot systems have been used as a means to provide local release of drugs intra-tumorally or adjacent to the cancerous tissue after surgical resection and have great potential.

A Novel Peptide from T-Cell Leukemia Translocation-Associated Gene (TCTA) Protein Inhibits Proliferation of a Small-Cell Lung Carcinoma

In 2009, we demonstrated that a peptide, which we named “Peptide A”, derived from the extracellular domain of T-cell leukemia translocation-associated gene (TCTA) protein, inhibited both RANKL-induced human osteoclastogenesis and pit formation of mature human osteoclasts. Here, we examined the effect of Peptide A on the cell proliferation of cell lines of small-cell lung carcinoma, breast cancer, and prostate cancer: RERF-LC-MA, MCF-7, and PC-3, respectively. Peptide A inhibited the proliferation of RERF-LC-MA, but not MCF-7 or PC-3. TCTA protein was immunohistologically detected in RERF-LC-MA and MCF-7. Thus, Peptide A may provide a novel strategy for the therapy of the patients with small-cell lung carcinoma, especially with bone metastasis. In addition, Peptide A may be useful for the treatment of various cancer patients with bone metastasis.

The ^(18)F-FDG uptake in non small cell lung carcinoma correlates with the DNA-grading of malignancy

In order to evaluate correlation of glucose metabolism and DNA ploidity of tumors, the uptake of 18F-Deoxyglucose (FDG) by PET prior to surgery and the DNA cotent and DNA-grading of malignancy (DNA-MG) of Schiff-stained nuclei obtained from fresh tumor fragments by means of image cytometry were studied, and thereafter the correlation between standardized uptake value (SUV) and (DNA-MG) was analysed in forty-nine patients with histologically proven non-small cell lung carcinoma (NSCLC). As a result of the DNA histograms of these 49 patients, 46 (93.88%) were aneuploid and only 3(6.12%) were tetraploid. A linear correlation of the SUV versus the (DNA-MG) (r=0.336, p=0.024) was found, demonstrating that 18F-FDG PET as a non-invasive metabolic imaging technique, may also provide inforrnation correlated to malignant DNA patterns which may be valuable in malignant differentiation and prognostic prediction.

Further understanding of an uncommon disease of combined small cell lung cancer： clinical features and prognostic factors of 114 cases

Objective： Combined small cell lung cancer （C-SCLC） is an uncommon subgroup of small cell lung cancer （SCLC） and few clinical data can be referred. Our study is to investigate the clinical features and prognostic factors of C-SCLC, as well as the role of multimodality treatment.Methods： Between January 2004 and December 2012, patients with histologically diagnosed C-SCLC were retrospectively analyzed. The survivals were evaluated with the Kaplan-Meier method. Univariate and multivariate analyses were used to evaluate potential prognostic factors.Results： One hundred and fourteen patients were enrolled, with a median age of 59 （range： 20-79） years old. The most common combined component was squamous cell carcinoma （52.6%）. Among these patients, the disease was stage I, II, III and IV in 9.6%, 19.3%, 46.5% and 24.6% of the patients, respectively. Eighty patients （70.2%） received at least two of the three modalities containing chemotherapy, radiotherapy and surgery. The median follow-up was 32.5 months. The median time of overall survival （OS） was 26.2 months. On univariate analysis, smoking （P=0.029）, Karnofsky performance score （KPS） 〈80 （P=0.000）, advanced TNM stage （P=0.000）, no surgery （P=0.010）, positive resection margin （P=0.000）, positive lymph nodes ≥4 （P=0.000）, positive lymph node ratio 〉10% （P=0.000） and non-multimodality treatment （P=0.004） were associated with poor OS. Multivariate analysis confirmed that smoking, advanced TNM stage, positive resection margin and positive lymph nodes ratio 〉 10% were poor prognostic features. Conclusions： C-SCLC has a relatively early stage and good prognosis, which may due to the underestimated diagnosis in non-surgical patients. Multimodality therapy is recommended, especially for limited disease. Smoking, advanced TNM stage, positive resection margin and positive lymph nodes ratio 〉10% are poor prognostic factors.

Relapse of both small cell lung cancer and Lambert-Eaton myasthenic syndrome after a 13-year disease-free survival period

Lambert-Eaton myasthenic syndrome(LEMS) is a paraneoplastic syndrome and only 3%of small cell lung carcinoma(SCLC) patients have LEMS.Moreover,the recurrence of SCLC after a disease-free survival(DFS) of more than 10 years is rare.We report a patient who had a recurrence of both SCLC and LEMS after a 13-year DFS period.A 69-year-old man was diagnosed with LEMS and SCLC(cT0N2M0,stage ⅢA) 13 years ago.Chemoradiotherapy was performed and a complete response was achieved.With anticancer treatment,the LEMS symptoms was alleviated.At the age of 82 years,gait disturbance appeared followed by left supraclavicular lymphadenopathy and further examination revealed the recurrence of SCLC.Careful screening for the recurrence of SCLC might be needed when the patient has recurrent or secondary paraneoplastic neurological syndrome even after a long DFS period.

Nedaplatin/Gemcitabine Versus Carboplatin/Gemcitabine in Treatment of Advanced Non-small Cell Lung Cancer: A Randomized Clinical Trial

Objective： To evaluate the efficacy and safety of nedaplatin/gemcitabine （NG） and carboplatin/gemcitabine （CG） in the management of untreated advanced non-small cell lung cancer （NSCLC）. Methods： Sixty-two patients with previously untreated advanced NSCLC were recruited between June 2006 and November 2007. Subjects were randomly assigned to the NG arm （n=30） and the CG arm （n=32）. Only patients （24 and 25 in the NG and CG arms, respectively） who completed 〉2 chemotherapy cycles were included in the data analysis. The primary outcome measure was the objective response rate （ORR）. The secondary outcome measures included progression-free survival （PFS）, overall survival （OS） and adverse events. Results： There were no statistically significant differences in the efficacy measures （ORR, P=0.305; median PFS, P=0.298, median OS, P=0.961） or in the major adverse events （grade 3/4 neutropenia, P=0.666; grade 3/4 anemia, P=0.263; grade 3/4 thrombocytopenia, P=0.222） between the two treatment arms. However, there was a trend towards higher ORR （37.5% vs. 24.0%）, longer PFS （6.0 vs. 5.0 months）, and less adverse events in the NG arm. Conclusion： NG regimen seems to be superior over CG regimen for advance NSCLS, but further investigation is needed to validate this superiority.

Extrapulmonary small cell carcinoma of lymph node: Pooled analysis of all reported cases

AIM: To study clinical outcomes and management of lymph nodes extrapulmonary small cell carcinoma(LNEPSCC). METHODS: Herein, we perform a systematic search of published literature in the PubMed and EMBASE databases for studies describing LNEPSCC. For uniformity of reporting, LNEPSCC was staged as limited if it involved either single lymph node station or if surgery with curative intent had been undertaken. The disease was staged extensive if it involved two or more lymph node regions.RESULTS: The systematic literature review yielded eight descriptions(n = 14) involving cervical, submandibular and inguinal lymph nodes. Eleven(64.7%) patients had limited disease(LD) and six(35.3%) had extensive disease(ED) at presentation. Chemotherapy(n = 6, 35.3%) or surgery(n = 4, 23.5%) were the most common form of treatment given to these patients. Complete response was achieved in 12(70.6%) of the patients. Median(interquartile range) progression free survival and overall survival was 15(7-42) mo and 22(12.75-42) mo respectively. Of the three illustrative cases, two patients each had ED at presentation and achieved complete remission with platinum based combination chemotherapy.CONCLUSION: LNEPSCC is a rare disease with less than 15 reported cases in world literature. Surgical resection with curative intent is feasible in those with LD while platinum based combination chemoradiation is associated with favorable outcomes in patients with ED. Prognosis of LNEPSCC is better than that of small cell lung cancer in general.

KRAS Exon 3 and PTEN Exon 7 Mutations in Small-cell Lung Cancer

Small cell lung cancer (SCLC) is recognized as one of the most aggressive and fatal malignant tumors. No significant improvement has been made to prolong the survival of SCLC patients. This study aimed to examine the mutation status of K-Ras (KRAS) and phosphatase and tensin homolog (PTEN) in SCLC patients in order to identify potential therapeutic targets for SCLC. Nineteen primary SCLC tumor specimens were enrolled in the study. Direct sequencing was perfonned to detect the mutations of KRAS exon 3 and PTEN exon 7 in the specimens. Kaplan- Meier and Cox regression analysis was performed to determine the overall survival (OS) of these SCLC patients. KRAS exon 3 mutation was found in 4 (21%) SCLC patients, and PTEN exon 7 mutation in only 1 (5%) SCLC patient. Kaplan Meier analysis showed that clinical stage and brain metastasis were significantly associated with OS (both P<0.05), but neither KRAS exon 3 mutation nor PTEN exon 7 mutation was significantly associated with OS (P>0.05). Cox proportional hazards regression model indicated that extensive stage of disease was the only independent negative prognostic factor for OS in SCLC patients. In conclusion, KRAS exon 3 and PTEN exon 7 mutations had no significant impact on OS of SCLC patients. Further study is still necessary to validate the molecular profiles of SCLC.

Molecular Mechanisms Contributing to Resistance to Tyrosine Kinase-Targeted Therapy for Non-Small Cell Lung Cancer

One of the most important pathways in non-small cell lung cancer(NSCLC) is the epidermal growth factor receptor(EGFR) pathway. This pathway affects several crucial processes in tumor development and progression,including tumor cell proliferation,apoptosis regulation,angiogenesis,and metastatic invasion.Targeting EGFR is currently being intensely explored.We are witnessing the development of a number of potential molecular-inhibiting treatments for application in clinical oncology.In the last decade,the tyrosine kinase(TK) domain of the EGFR was identified in NSCLC patients,and it has responded very well with a dramatic clinical improvement to TK inhibitors such are gefitinib and erlotinib.Unfortunately,there were primary and/or secondary resistance to these treatments,as shown by clinical trials.Subsequent molecular biology studies provided some explanations for the drug resistance phenomenon.The molecular mechanisms of resistance need to be clarified.An in-depth understanding of these targeted-therapy resistance may help us explore new strategies for overcoming or reversing the resistance to these inhibitors for the future of NSCLC treatment.

Advances in adjuvant systemic therapy for non-small-cell lung cancer

Non-small-cell lung cancer remains a leading cause of death around the world. For most cases, the only chance of cure comes from resection for localised disease, however relapse rates remain high following surgery. Data has emerged over recent years regarding the utility of adjuvant chemotherapy for improving disease-free and overall survival of patients following curative resection. This paper reviews the clinical trials that have been conducted in this area along with the studies integrating radiation therapy in the adjuvant setting. The role of prognostic gene signatures are reviewed as well as ongoing clinical trials including those incorporating biological or targeted therapies.

Paclitaxel-etoposide-carboplatin/cisplatin versus etoposidecarboplatin/cisplatin as first-line treatment for combined small-cell lung cancer: a retrospective analysis of 62 cases

Objective: To compare the efficacy and adverse effects of paclitaxel-etoposide-carboplatin/cisplatin(TEP/TCE) regimen with those of etoposide-carboplatin/cisplatin(EP/CE) regimen as first-line treatment for combined small-cell lung cancer(CSCLC).Methods: A retrospective study was conducted on 62 CSCLC patients who were treated at Tianjin Medical University Cancer Institute and Hospital from July 2000 to April 2013 and administered with TEP/TCE regimen(n=19) or EP/CE regimen(n=43) as first-line CSCLC treatment. All patients received more than two cycles of chemotherapy, and the response was evaluated every two cycles. The primary endpoint was overall survival(OS), and the secondary endpoints were progression-free survival(PFS), objective response rate(ORR), disease control rate(DCR), and adverse effects. Results: ORR between the TEP/TCE and EP/CE groups showed a statistical difference(90% vs. 53%, P=0.033). Both groups failed to reach a statistical difference in DCR(100% vs. 86%, P=0.212). The median PFS and OS of the TEP/TCE group were slightly longer than those of the EP/CE group, although both groups failed to reach a statistical difference(10.5 vs. 8.9 months, P=0.484; 24.0 vs. 17.5 months, P=0.457). However, stratified analysis indicated that the PFS of patients with stages III and IV CSCLC showed marginally significant difference between the TEP/TCE and EP/CE groups(19.5 vs. 7.6 months; P=0.071). Both rates of grade IV bone marrow depression and termination of chemotherapy in the TEP/TCE group were significantly higher than those in the EP/CE group(26.3% vs. 7.0%, P=0.036; 31.6% vs. 14.7%, P=0.004). Conclusion: The TEP/TCE regimen may not be preferred for CSCLC, and this three-drug regimen requires further exploration and research. To date, the EP/CE regimen remains the standard treatment for CSCLC patients.
