Guidelines for the clinical application of the Xihuang pill for the prevention and treatment of breast hyperplasia diseases.

CONTEXT: The Xihuang pill (XHP) is a traditional Chinese medicine formulation that has been historically used in the prevention and treatment of proliferative breast diseases. However, there is a lack of guidelines that offer recommendations for its clinical use. OBJECTIVE: The task force from the Chinese Guangdong Pharmaceutical Association aims to develop evidence-based guidelines for XHP to prevent and treat proliferative breast diseases. METHODS: We searched six Chinese and English electronic databases, including the China National Knowledge Infrastructure, the Chinese Scientific Journal Database, the Wanfang Medical Database, PubMed, and Embase, up to November 1, 2022. Publications (case reports, clinical observation, clinical trials, reviews) on using XHP to treat proliferative breast diseases were manually searched. The search terms were Xihuang pill, hyperplasia of the mammary gland, breast lump, and mastalgia. The writing team developed recommendations based on the best available evidence. RESULTS: Treatment should be customized based on syndrome identification. We recommend using XHP for the prevention and treatment of breast hyperplasia disease when a patient presents the following syndromes: concurrent blood stasis syndrome, concurrent phlegm-stasis syndrome, and concurrent liver fire syndrome. Safety indicators, including blood analysis and liver and kidney function monitoring, should be performed regularly during treatment. CONCLUSIONS: Current clinical evidence suggests that XHP can be used as a standalone treatment or in conjunction with other medications to prevent and manage breast hyperplasia diseases. More randomized controlled studies are warranted to establish high-quality evidence of its use.

Lung adenocarcinoma with an uncommon CCDC85A-ALK fusion responding to alectinib: A case report.

A 55-year-old Chinese man with a right lung mass and lymph node metastasis (T4N3M0 IIIB) was diagnosed with lung adenocarcinoma after a CT-guided biopsy. With the wide application of next-generation sequencing (NGS) in tumour detection, we found a rare CCDC85A-ALK fusion. The patient received alectinib, which had marked efficacy. This is the first report of a lung adenocarcinoma patient harbouring a new uncommon anaplastic lymphocyte kinase fusion that showed a remarkable response to alectinib. NGS aids in selecting treatment in non-small cell lung cancer patients.

A refractory case of CDK4-amplified spinal astrocytoma achieving complete response upon treatment with a Palbociclib-based regimen:a case report.

BACKGROUND: Spinal cord astrocytoma is a rare neoplasm, and patients usually recur within months after surgery. There is currently a lack of consensus regarding post-operative treatment. Clinical data on the activity of systemic treatment like chemoradiotherapy and anti-angiogenic agents also remained scant. Next-generation sequencing (NGS) -based genomic profiling thus may help identify potential treatment options for a subset of patients that harbor actionable genetic alterations. CASE PRESENTATION: We reported for the first time a refractory case of grade III spinal cord astrocytoma that underwent two surgeries but eventually progressed following post-operative chemoradiotherapy plus bevacizumab. Hybridization capture-based NGS using a 381-gene panel disclosed cyclin dependent kinase 4 (CDK4) amplification and after receiving a triplet regimen containg palbociclib for 15 months, the patient achieved complete response. CONCLUSIONS: This case demonstrated the importance of genetic profiling and the benefit of a multi-modality treatment strategy in cancer management.

Lung abscess secondary to lung cancer with Eikenella corrodens and Streptococcus anginosus: a case report.

BACKGROUND: Eikenella corrodens and Streptococcus anginosus, which are primary colonization bacteria of the normal flora of the oropharynx, are infrequent bacteria, especially the former. Here, we report a case of lung abscess with a coinfection of Eikenella corrodens and Streptococcus anginosus in a lung cancer patient. CASE PRESENTATION: A 66-year-old Chinese man with lung cancer was admitted to the hospital, complaining of a cough and expectoration for five months and fever for two months. After a series of inspections to differentiate a cancer-related fever from an infectious fever, he was diagnosed with lung abscess. Draining pus culture demonstrated Eikenella corrodens and Streptococcus anginosus. After more than 1 month of antibiotic therapy and draining in total, he gradually recovered to fight against lung cancer. CONCLUSION: This report highlights the increased pathogenicity of Eikenella corrodens and Streptococcus anginosus in an immunocompromised cancer patient, especially after a few invasive operations. Additionally, even though a patient has been diagnosed with cancerous fever, strong vigilance is needed in case an infection arises.

Nab-paclitaxel (abraxane)-based chemotherapy to treat elderly patients with advanced non-small-cell lung cancer: a single center, randomized and open-label clinical trial.

BACKGROUND: The purpose of this study is to evaluate the clinical efficacy and safety of abraxane-based chemotherapy with/without nedaplatin in elderly patients with non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS: From October 2009 to January 2013, 48 elderly patients (≥65 years) with NSCLC were investigated in this clinical trial. The patients were randomized and equally allocated into arms A and AP: (A) abraxane (130 mg/m(2), days 1, 8); (B) abraxane + nedaplatin (20 mg/m(2) days 1-3, q3w). The parameters of objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and side effects were evaluated between two arms. RESULTS: Over 80% of the patients completed four cycles of chemotherapy. The total ORR was 21.3%, DCR was 55.3%, PFS 4.5 months and OS 12.6 months. No significant difference was found between arms A and AP in terms of ORR (16.7% vs. 26.1%, P=0.665) or DCR (55.3% vs. 56.5%, P=0.871). The median PFS in arm A was 3.3 months [25-75% confidence interval (CI): 3.1-7.2] and 5.5 months (25-75% CI: 3.2-7.0) in arm AP with no statistical significance (P=0.640). The median OS in arm A was 12.6 months (25-75% CI: 5.7-26.2) and 15.1 months (25-75% CI: 6.4-35.3) in arm AP with no statistical significance (P=0.770). The side effects were mainly grade 1-2. The incidence of grade 3-4 toxicities was 29.1% in arm A and 62.5% in arm AP with a statistical significance (P=0.020). CONCLUSIONS: Compared with combined therapy, abraxane alone chemotherapy was beneficial for elderly NSCLC patients with better tolerability and less adverse events, whereas did not significantly differ in terms of ORR, DCR, PFS or OS.

Vitamin E intake is inversely associated with NAFLD measured by liver ultrasound transient elastography.

Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases, whose severe form is associated with oxidative stress. Vitamin E as an antioxidant has a protective potential in NAFLD. Whether dietary intake of vitamin E, supplementary vitamin E use, and total vitamin E have a preventive effect on NAFLD requires investigation. A cross-sectional study used data from the National Health and Nutrition Examination Survey (2017-2020) was conducted. Vitamin E intake, including dietary vitamin E, supplementary vitamin E use, and total vitamin E, was obtained from the average of two 24-h dietary recall interviews. The extent of hepatic steatosis was measured by liver ultrasound transient elastography and presented as controlled attenuated parameter (CAP) scores. Participants were diagnosed with NAFLD based on CAP threshold values of 288 dB/m and 263 dB/m. The statistical software R and survey-weighted statistical models were used to examine the association between vitamin E intake and hepatic steatosis and NAFLD. Overall, 6122 participants were included for NAFLD analysis. After adjusting for age, gender, race, poverty level index, alcohol consumption, smoking status, vigorous recreational activity, body mass index, abdominal circumference, hyperlipidemia, hypertension, diabetes, and supplementary vitamin E use, dietary vitamin E was inversely associated with NAFLD. The corresponding odds ratios (OR) and 95% confidence intervals (CI) of NAFLD for dietary vitamin E intake as continuous and the highest quartile were 0.9592 (0.9340-0.9851, P = 0.0039) and 0.5983 (0.4136-0.8654, P = 0.0091) (Ptrend = 0.0056). Supplementary vitamin E was significantly inversely associated with NAFLD (fully adjusted model: OR = 0.6565 95% CI 0.4569-0.9432, P = 0.0249). A marginal improvement in total vitamin E for NAFLD was identified. The ORs (95% CIs, P) for the total vitamin E intake as continuous and the highest quartile in the fully adjusted model were 0.9669 (0.9471-0.9871, P = 0.0029) and 0.6743 (0.4515-1.0071, P = 0.0538). Sensitivity analysis indicated these findings were robust. The protective effects of vitamin E significantly differed in the stratum of hyperlipidemia (Pinteraction < 0.05). However, no statistically significant results were identified when the threshold value was set as 263 dB/m. Vitamin E intake, encompassing both dietary and supplemental forms, as well as total vitamin E intake, demonstrated a protective association with NAFLD. Augmenting dietary intake of vitamin E proves advantageous in the prevention of NAFLD, particularly among individuals devoid of hyperlipidemia.

Prediction and verification of benignancy and malignancy of pulmonary nodules based on inflammatory related biological markers.

Objective: Inflammation plays an important role in the transformation of pulmonary nodules (PNs) from benign to malignant. Prediction of benignancy and malignancy of PNs is still lacking efficacy methods. Although Mayo or Brock model have been widely applied in clinical practices, their application conditions are limited. This study aims to construct a diagnostic model of PNs by machine learning using inflammation-related biological markers (IRBMs). Methods: Inflammatory related genes (IRGs) were first extracted from GSE135304 chip data. Then, differentially expressed genes (DEGs) and infiltrating immune cells were screened between malignant pulmonary nodules (MN) and benign pulmonary nodule (BN). Correlation analysis was performed on DEGs and infiltrating immune cells. Molecular modules of IRGs were identified through Consistency cluster analysis. Subsequently, IRBMs in IRGs modules were filtered through Weighted gene co-expression network analysis (WGCNA). An optimal diagnostic model was established using machine learning methods. Finally, external dataset GSE108375 was used to verify this result. Results: 4 hub IRGs and 3 immune cells showed significantly difference between MN and BN, C1 and C2 module, namely PRTN3, ELANE, NFKB1 and CTLA4, T cells CD4 naïve, NK cells activated and Monocytes. IRBMs were screened from black module and yellowgreen module through WGCNA analysis. The Support vector machines (SVM) was identified as the optimal model with the Area Under Curve (AUC) was 0.753. A nomogram was established based on 5 hub IRBMs, namely HS.137078, KLC3, C13ORF15, STOM and KCTD13. Finally, external dataset GSE108375 verified this result, with the AUC was 0.718. Conclusion: SVM model established by 5 hub IRBMs was able to effectively identify MN or BN. Accumulating inflammation and immune dysfunction were important to the transformation from BN to MN.

Posterior reversible encephalopathy syndrome associated with use of anlotinib to treat squamous cell carcinoma of the cervix: case report and literature review.

Background: Posterior reversible encephalopathy syndrome (PRES), a neurological disorder with an unknown aetiology, is characterised by visual impairment, headache, vomiting, seizures, and transient alterations in consciousness. Case report: We present the case of a 49-year-old woman with advanced cervical carcinoma who received second-line therapy with oral anlotinib (12 mg, days 1-14, every 21 days) and injectable tislelizumab (200 mg, day 1, every 21 days). After 7 days of anlotinib administration, she began experiencing symptoms suggestive of PRES and was diagnosed on day 11. Interruption of anlotinib and supportive treatment led to recovery of her binocular vision. The Naranjo score (+5) graded the causality of this reaction as probable, suggesting the possibility that the event may have been an adverse reaction to anlotinib. Ethics: This case report was approved by the Ethics Committee of the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine (Reference no. K-2023-068, 2023/06/09). Informed consent was obtained from the patient and her family.

Case Report: Clinical benefit from multi-target tyrosine kinase inhibitor and PARP inhibitor in a patient with cancer of unknown primary with BRCA1 large genomic rearrangement.

Background: Cancer of unknown primary (CUP), which accounts for 3%-5% of new cancer cases every year, involves the presence of a type of histologically confirmed metastatic tumors whose primary site cannot be confirmed by conventional diagnostic methods. This difficulty in identifying the primary site means that CUP patients fail to receive precisely targeted therapy. Most patients are treated with empiric chemotherapy, with a median survival of 6 months and even poorer prognosis within an unfavorable subset of CUP. Case report: An 80-year-old woman presented with masses in the abdomen. Following comprehensive imagological and immunohistochemical examinations, she was diagnosed with CUP. She emphatically declined chemotherapy; thus, anlotinib has been administered with patient consent since 02/07/2019, and stable disease (SD) was observed for 2 years. During subsequent treatment, a large genomic rearrangement in BRCA1 was identified in the patient via NGS, and SD was observed for a further 6 months following olaparib treatment. The type of LGR identified in this patient was discovered to be BRCA1 exon 17-18 inversion (inv), which has never been previously reported. Conclusion: For CUP patients, a chemo-free regimen seems to be acceptable as a first-line treatment, and NGS-guided targeted treatment could improve patient outcomes.

Effect of Fu's subcutaneous needling for cancer pain management: protocol for a pragmatic randomised controlled trial.

INTRODUCTION: Pain is a common symptom in patients with cancer, and pain management is crucial for these patients. Fu's subcutaneous needling (FSN) is a modern acupuncture therapy based on basic medicine commonly used in patients with pain. However, evidence of its effectiveness in treating cancer pain has not been systematically proven. Therefore, this pragmatic randomised controlled trial aims to evaluate the effectiveness and safety of FSN for cancer pain management. METHODS AND ANALYSIS: Overall, 120 eligible patients will be recruited and randomly assigned into two groups using block randomisation. Both groups will be administered analgesic drugs according to the National Comprehensive Cancer Network guidelines. The treatment group will receive FSN therapy one time a day for 6 days. Additionally, we will assess analgesic consumption as the primary outcome and the Numerical Rating Scale, outbreak pain, symptom assessment and adverse events as secondary outcomes to evaluate the effect and safety of FSN in treating cancer pain. The incidence of adverse events will be monitored to assess the safety of FSN. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Ethics Committee of the First Affiliated Hospital of Guangzhou University of Chinese Medicine (approval No: K(2021)096). The results will be published in a peer-reviewed journal, and trial participants will be informed via email and/or phone calls. TRIAL REGISTRATION NUMBER: ChiCTR2200056348.

Yifei Sanjie Formula or Placebo With Anlotinib as Second-Line or Above Treatment for Metastatic Non-Small-Cell Lung Cancer: Study Protocol for a Double-Blind, Placebo-Controlled Randomized Pilot Study.

BACKGROUND: Anlotinib is used as a third-line treatment for advanced non-small-cell lung cancer (NSCLC), but has limited clinical benefits and several side effects, such as diarrhea and acneiform skin rash. Traditional Chinese Medicine (TCM) is commonly used to treat cancers in China. Chinese herbal medicines may have the potential as adjuvant therapies to reduce toxicity and improve the efficacy of treatments for NSCLC. Given the positive outcomes of basic research, we plan to evaluate whether the addition of the Chinese herbal medicine Yifei Sanjie formula (YFSJF) to anlotinib can improve the progression-free survival (PFS) of advanced NSCLC patients. METHODS: A multicenter, randomized, double-blind, placebo-controlled parallel-group controlled pilot trial will be performed. Forty eligible patients will be randomized in a ratio of 1:1 to the intervention (YFSJF + anlotinib) and control (placebo + anlotinib) groups. Participants will be advised to take 12 mg/day of anlotinib on days 1 to 14 of each 21-day cycle. YFSJF or placebo will be administered (15 g twice daily) during each cycle until progression of disease (PD). The primary outcome will be progression-free survival (PFS), and the secondary outcomes will be overall survival (OS), the objective response rate (ORR), and patient-reported outcomes (PRO). Tumors will be assessed based on RECIST v. 1.1 after every 2 cycles of treatment. The M. D. Anderson Symptom Inventory-Lung Cancer (MDASI-LC) will be used to evaluate PRO at baseline and weekly thereafter until PD. DISCUSSION: This will be the first trial to evaluate the effectiveness and safety of TCM combined with anlotinib for the treatment of NSCLC. The results of this randomized controlled trial will fill a gap in the research by showing whether YFSJF combined with anlotinib can improve PFS in NSCLC patients. TRIAL REGISTRATION: The study was registered on June 8th, 2021 on Chinese Clinical Registry; registration number ChiCTR2100047143. (https://www.chictr.org.cn/index.aspx). ETHICS AND DISSEMINATION: The Ethics Committee of the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine approved the study protocol (approval no.: K2020151, 2021/08/19). The study will also be supervised and managed by the Ethics Committee.

Qu-Yu-Jie-Du Decoction Ameliorates Dextran Sulfate Sodium-Induced Colitis in Mice by Modulation of Neutrophils and Macrophage Infiltration.

Background: Inflammatory bowel disease (IBD) is becoming a global disease. A percentage of IBD patients will not react to therapy or will lose their response. Qu-Yu-Jie-Du Decoction (QYJD) is a traditional Chinese medicine formula commonly used for intestinal diseases. It has been reported that QYJD has an anti-inflammatory effect, but the mechanism is not fully understood. In this study, we mainly evaluated the anti-inflammatory effect of QYJD and explored the possible mechanisms. Methods: Twenty-four BALB/c mice were randomly divided into 4 groups according to their body weight, namely, the control group, the dextran sulfate sodium (DSS) group, the DSS + QYJD group, and the QYJD group. Mice were given 3% DSS drinking water freely, and at the same time, mice were given normal saline or QYJD (4.44 mg/g/d), respectively. Mental state, faeces, and weight were recorded every day. On the 10th day, the mice were sacrificed and collected for investigation. The length of the mice colon was measured. Histological analysis was used to detect the morphological changes in the colon. Immunohistochemistry was used to measure the infiltration of macrophages (F4/80, CD163) and neutrophils (Ly6G). Colorimetry was used to detect the myeloperoxidase (MPO) activity of colon tissues. ELISA was utilized to detect associated inflammatory cytokines and chemokines in colon tissues. Results: QYJD alleviated the weight loss and colitis symptoms of mice caused by DSS. QYJD fought against the shortening of the intestine caused by DSS; that is, it improved the decline of intestinal compliance in mice and had a protective effect on colon tissues. The mechanisms were related to downregulating macrophages and neutrophils in colon tissues of infiltration. Besides, QYJD simultaneously reduced the activity of myeloperoxidase activity (MPO) and the contents of IL-1ß, IL-6, TNF-α, TGF-ß, CCL2, and CXCL2 in colon tissues. Conclusions: QYJD can ameliorate DSS-induced colitis in mice and the mechanism is connected with a reduction in neutrophil and macrophage infiltration.

Efficacy of Disitamab Vedotin in a heavily pre-treated HER2 positive lung adenocarcinoma patient: case report and literature review.

Cancer therapies targeting human epidermal growth factor receptor 2 (HER2) have been attracting increasing attention worldwide, especially in lung adenocarcinoma. Disitamab vedotin is an antibody-drug conjugate designed for targeting HER2 that has been approved for urothelial carcinoma and gastric cancer. However, there is still a lack of clinical evidence for applying Disitamab vedotin in lung adenocarcinoma. Herein, we reported a case of a 52-year-old man with advanced lung adenocarcinoma carrying HER2 amplification as well as HER2 immunohistochemistry (IHC) 2 + who underwent treatment with Disitamab vedotin after disease progression. The patient was treated with chemotherapy, anti-angiogenesis therapy, and immunotherapy as first-line therapy, achieving a remarkable progression-free survival of 16 months. After the disease continued to continuous progress, the patient was administrated with Disitamab vedotin, which resulted in improvement of both the lung lesions and the brain lesions. Our findings provide a valuable reference for the utilization of Disitamab Vedotin in HER2 IHC2+ lung adenocarcinoma.

Zhengyuan capsules for the treatment of chemotherapy-induced cancer-related fatigue in stage IIIB-IV unresectable NSCLC: study protocol for a randomized, multi-center, double-blind, placebo-controlled clinical trial.

Background: Patients with advanced non-small cell lung cancer (NSCLC) frequently experience cancer-related fatigue (CRF) during or after chemotherapy. Traditional Chinese medicine (TCM) can effectively relieve CRF, although the clinical evidence is insufficient due to the absence of extensive and rigorous clinical studies. Zhengyuan capsules have both tonifying and dispersing effects, and its ability to alleviate CRF has been verified in mice. This study aimed to provide evidence for the role of proprietary Chinese medicines in alleviating CRF in advanced NSCLC patients. Methods: A multi-center, randomized, double-blind, placebo-controlled clinical trial has been designed to evaluate the efficacy and safety of Zhengyuan capsules for CRF in stage IIIB-IV unresectable NSCLC patients undergoing chemotherapy. Thirty eligible participants will be randomized into two groups at a 1:1 ratio during chemotherapy using the centralized interactive web response system. All patients will receive conventional platinum-based dual-drug chemotherapy and Zhengyuan capsules or simulant for 42 consecutive days starting on the first day of the first week of chemotherapy. The primary outcome is the difference between baseline and post-treatment CRF in the two groups, which will be assessed using the Brief Fatigue Inventory (BFI) score. Secondary outcome measurements include the Revised Piper's Fatigue Scale (RPFS)-Chinese Version, European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Module C30 (EORTC QLQ-C30) v3.0 combined with EORTC QLQ-LC13 (Lung Cancer 13), clinical symptom score, hematology exploratory index, and progression-free survival. And safety indicators such as blood, urine, fecal routine, liver and kidney function, coagulation, and electrocardiogram will be performed before chemotherapy. Data will be analyzed according to intention-to-treat (ITT) and per-protocol (PP) principles; Empowerstats and R will be applied for statistical analysis. Discussion: This trial will provide data on the efficacy and safety of Zhengyuan capsules for treating CRF in stage IIIB-IV unresectable NSCLC patients undergoing chemotherapy. It will also provide a basis for the feasibility of a large-scale clinical trial. Trial Registration: The clinical trial was registered on 19 November 2020 through https://www.chictr.org.cn (registration number: ChiCTR2000040061).

The Prognostic Value of Serum Apolipoprotein A-I Level and Neutrophil-to-Lymphocyte Ratio in Colorectal Cancer Liver Metastasis.

Background: Colorectal cancer liver metastasis (CRLM) is a high degree of malignancy with rapid disease progression and has a poor prognosis. Both serum apolipoprotein A-I (ApoA-I) and neutrophil-to-lymphocyte ratio (NLR) play key roles in anti-inflammation and antitumor. This study is aimed at evaluating the implication of serum ApoA-I level in combination with NLR in the prognosis of CRLM. Methods: We retrospectively analyzed the serum ApoA-I level and NLR in 237 patients with CRLM. Cox regression analyses were used to identify the independent prognostic significance of these indicators. Kaplan-Meier method and Log-rank test were applied to compute overall survival (OS). Both the ApoA-I and NLR were divided into three levels, according to their medians. A risk-stratified prediction model was established to evaluate the prognosis of patients with CRLM. The ROC curve AUC values were applied to evaluate the capability of the model. Results: Higher levels of ApoA-I and lower NLR were strongly associated with prolonged OS (Log-rank test, P < 0.05). The patients were then grouped into three queues according to the ApoA-I level and NLR. There was a crucial diversity in the OS (P < 0.001) between the high-risk (ApoA - I ≤ 1.03 g/L and NLR > 3.24), medium-risk (ApoA - I > 1.03 g/L or NLR ≤ 3.24) and low-risk groups (ApoA - I > 1.03 g/L and NLR ≤ 3.24). The AUC value of the prediction model (AUC = 0.623, 95% CI: 0.557-0.639, P = 0.001) was higher than other individual indicators (including ApoA-I, NLR, cT classification, and cN classification). Additionally, the association of the prediction model and cTN classification (AUC = 0.715, 95% CI: 0.606-0.708, P < 0.001) was better than the model and cTN classification alone. Conclusion: The combination of ApoA-I level and NLR could be a prognostic indicator for CRLM.

Construction of a Novel Lung Adenocarcinoma Immune-Related lncRNA Pair Signature.

BACKGROUND: A growing number of studies have demonstrated that immune-related long noncoding ribonucleic acids (irlncRNAs) are potential prognostic factors for lung adenocarcinoma. Two-gene combination patterns could improve the sensitivity of prognostic models, providing us a novel signature construction concept that we applied to lung adenocarcinoma. METHODS: Gene expression and clinical data were downloaded from the Lung Adenocarcinoma project of The Cancer Genome Atlas (TCGA) database. We applied a co-expression analysis with immune genes obtained from the ImmPort database to recognize irlncRNA. The matrix of irlncRNA pairs was established by a cyclic comparison of each lncRNA pair expression level. Univariate and multivariate Cox regressions and Lasso penalized regression analysis were applied to construct the risk model. Patients with lung adenocarcinoma were divided into high- and low-risk groups, according to the Akaike Information Criterion (AIC) values of the receiver operating characteristic (ROC) curve. Then, we evaluated our signature under various clinical settings: clinical-pathological characteristics, tumor-infiltrating immune cells, checkpoint-related biomarkers, targeted therapy, and chemotherapy. RESULTS: Based on the 239 differently expressed irlncRNAs, we constructed an 11-irlncRNA pair signature. The area under the curve (AUC) of the ROC curve for the signature to predict the 4-year survival rate was 0.819, and the cut-off point was recognized as 1.003. Subsequent analysis showed that our signature can effectively distinguish unfavorable survival outcomes, prognostic clinic-pathological characteristics, and specify tumor infiltration status. Highly expressed immune checkpoint-related genes, as well as higher chemosensitivity, were correlated to the low-risk group. CONCLUSION: We constructed a novel lung adenocarcinoma irlncRNA signature with promising prognostic value using the TCGA database, based on paired irlncRNAs and not relying on lncRNAs special expression levels.

Efficacy of treatment for acneiform eruptions related to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) for non-small cell lung cancer (NSCLC): A protocol of systematic review and network meta-analysis.

BACKGROUND: Acneiform eruptions from epidermal growth factor receptor tyrosine kinase inhibitors is a frequent adverse event in non-small cell lung cancer patients but the efficacy of its treatment including antibiotics, corticosteroid, sunscreen is still poorly understood. METHODS: Eight electronic databases (PubMed, EMBASE, ClinicalTrials.gov, etc) will be searched from inception to April 2020. Risk of bias of randomized controlled trials will be assessed in terms of the Risk of Bias 2 (RoB 2) tool. Eligible randomized controlled trials will be enrolled for a Bayesian network meta-analysis using R software. RESULTS: This study is still ongoing and the results will be submitted and published in a peer-reviewed scientific journal. CONCLUSION: We hope the results of this study will provide reliable evidence for the management of acneiform due to epidermal growth factor receptor tyrosine kinase inhibitors for non-small cell lung cancer. ETHICS AND DISSEMINATION: Ethical approval is not applicable for this study is based on published trials. PROTOCOL REGISTRATION NUMBER: CRD42020206724.

Multicenter, randomized, double-blind, controlled trial of transcutaneous electrical nerve stimulation for pancreatic cancer related pain.

BACKGROUND: Up to 80% of patients with pancreatic cancer experience abdominal and back pain. Although pharmacologic medications provide some relief, many report inadequate analgesia and adverse effects. Transcutaneous electrical nerve stimulation (TENS) is a non-invasive physical modality and had been widely applied for pain relieving, yet no study has investigated the effectiveness of TENS for pain in pancreatic cancer. METHODS: Eligible patients were randomly assigned in a 1:1 ratio to TENS group or control group. The primary outcome was percentage change of numerous rating scale (NRS) after treatment. Secondary outcomes included percentage change of analgesic medication consumption and effect on constipation and poor appetite. RESULTS: One hundred seventy-one patients were recruited (84 to control group and 87 to TENS group). NRS in TENS group has been largely decreased 77.9% right after treatment and 27.1% in 2 hours, before applying any analgesic medication, while that in control group was slightly downregulated right after treatment but gave a trend to increase at 1, 2, and 3 hours. When comparing both groups, pain was significantly well controlled without analgesic medication supplement in TENS group at 0 hour (difference in mean percent change in NRS = 50.0 [95% CI, 50-51.4], P < .01) and 3 hours (difference in mean percent change in NRS = 134.0 [95% CI, 130.0-142.7], P < .01) after treatment, and this analgesic effect last to 3 weeks after treatment cycle (difference in mean percent change in NRS = 22.5 [95% CI, 17.6-27.3], P < .01) without increase of analgesic medication consumption. CONCLUSIONS: TENS reduces pain without increase analgesic medication consumption in patients with pancreatic cancer pain. It provides an alternative therapy for pain in pancreatic cancer. CLINICAL TRIAL REGISTRATION: This study was registered at ClinicalTrials.gov, identifier NCT03331055.

Metastatic Colorectal Cancer Patient With Microsatellite Stability and BRAFV600E Mutation Showed a Complete Metabolic Response to PD-1 Blockade and Bevacizumab: A Case Report.

A vast majority of colorectal cancer (CRC) patients with microsatellite stability (MSS) or proficient mismatch repair (pMMR) are refractory to immunotherapeutic strategies. The current research focusses on the combined treatment strategies for identification and optimization in order to improve the efficacy of immunotherapy among patients with microsatellite stability (MSS), who account for the majority of metastatic colorectal cancer (mCRC) cases. mCRC patients harboring MSS and the BRAFV600E mutation show a worse prognosis and barely benefit from immunotherapy. In this report, we discuss the case of a mCRC patient with MSS and BRAFV600E mutation, who exhibited significant response to the combined treatment with nivolumab and bevacizumab, and has been exhibiting a progression-free survival (PFS) of more than 17 months. Our findings indicate that combined anti-angiogenic therapy can improve the efficacy of immunotherapy, which results in the prolong survival of the patient. This is a case report on MSS and BRAFV600E colorectal cancer which presents with a response to immunotherapy and anti-angiogenic therapy.
