Relationship between dynamic changes of psychological distress and quality of life in Chinese early breast cancer patients

Objective: To explore the dynamic changes of Distress Thermometer scores and the relationship between psychological distress and quality of life in Chinese early breast cancer patients during chemotherapy. Methods: This prospective study enrolled 110 Chinese postoperative early breast cancer patients between March 2019 and December 2019. The psychological distress and quality of life (QOL) of patients were assessed by using the psychological distress management screening tool and the patient quality of life scale. Logistic regression model was used to analyze the influencing factors of psychological distress degree. The correlation between distress thermometer (DT) score changes and quality of life was analyzed by Pearson correlation analysis. Results: In total, 96 valid cases were analyzed. Before chemotherapy, 47 cases (49.0%) had DT score ≥4 points. After 2 cycles of chemotherapy, 40 cases (41.7%) had DT score ≥4 points. Thirty-four patients (35.4%) had DT score ≥4 points after chemotherapy. The DT score after chemotherapy was lower than that before chemotherapy and after 2 cycles of chemotherapy. Univariate analysis showed that income level and pathological stage were still significant related to the detection of DT score ≥4 points after chemotherapy (P<0.05). The changes of DT scores before and after chemotherapy were negatively correlated with the changes of quality of life ( r=-0.298, P=0.003). Conclusions: The detection rate of psychological distress in patients with early breast cancer during chemotherapy showed a decreasing trend. Income level and tumor stage are significant factors affecting the psychological distress of patients. There is a significant correlation between the psychological distress and the quality of life during chemotherapy. We should pay attention to the evaluation and monitoring state of psychological distress of patients during chemotherapy.

Removable partial prosthesis combined with swallowing training is an efficient clinical solution for oral cancer post-operation patients with palatal defect and dysphagia: a prospective study.

Dysphagia is one of the major complications of oral cancer patients, and is disturbing thousands of patients worldwide. Our study aim to evaluate the clinical efficacy of prosthesis combined with swallowing training on palatal defect and dysphagia in post-operative oral cancer patients. Sixteen oral cancer patients with palatal defect and dysphagia post-operation were treated with removable prosthesis and individualized swallowing function training. Swallowing function of patients before and after treatment was analyzed and compared by videofluoroscopic swallowing examination. The severity of depression and life quality were evaluated by Depression Scale (SDS) and Functional Assessment of Cancer Therapy-Head and Neck (FACT-H&N) scores, respectively. Oral transit time (OTT) significantly shortened after treatment (P < 0.01), and Penetration-Aspiration Scale (PAS) scores was significantly higher after treatment (P < 0.001). Different consistency bolus showed different risk of aspiration. Thickened liquids were related to lower PAS scores (P < 0.001). SDS standard score was significantly lower after treatment (P < 0.05). The total score of FACT-H&N after treatment was significantly higher (P < 0.05). No patients came back for regressed swallowing function during the follow-up period (17.06 ± 2.376months). Removable prosthesis and swallowing training can significantly improve swallowing function, reduce depression degree, and improve quality of life (QOL). Removable prosthesis combined with swallowing training is a cheap and effective method to improve QOL in patients with palate defect and dysphagia after oral cancer.

Development of a Remote Examination of Deglutition Based on Consensus Surveys of Clinicians (Part II): Reliability and Validity in Healthy Elderly Individuals and Oral Cancer Patients.

In our prior published study, we extracted evaluation items suitable for remote administration, and made a relatively simple Remote Examination of Deglutition (RED). This study aimed at verifying the reliability and validity of RED. The participants were 21 healthy elderly individuals and 72 postoperative oral cancer (OC) patients. OC patients underwent videofluoroscopic dysphagia examination, and severity was judged on the dysphagia severity scale (DSS). Reliability and validity of RED were examined in all participants under face-to-face conditions, in comparison with the Mann Assessment of Swallowing Ability (MASA). Reliability and validity of remote administration of RED were examined in 40 participants. ROC curves were used to find cut-off RED scores to predict aspiration and deglutition disorders. The Cronbach's alpha coefficient for the items was 0.882. There was a high correlation between the total score of RED and MASA in the face-to-face condition. When RED score was compared among different severity groups (DSS1–4, DSS5–6, and DSS7), the total and oral preparatory stage scores revealed significant group differences. The area under the curve (AUC) for aspiration based on the ROC curve was 0.913, with a sensitivity/specificity of 0.80/0.98. The AUC for deglutition disorders was 0.819, with a sensitivity/specificity of 0.74/0.67. In both face-to-face and remote conditions, the reliability of RED was good.The reliability and validity of RED were confirmed. RED has shown the potential to assess the likelihood of aspiration and deglutition disorders in OC patients remotely as an initial assessment tool.

Association between depression and anxiety status of breast cancer patients before adjuvant chemotherapy and chemotherapy-induced adverse events.

Patients with breast cancer are more likely to experience psychological distress than the general population. This study aimed to explore the relationship between depression and anxiety status measured before chemotherapy and adverse events during adjuvant chemotherapy in Chinese breast cancer patients. This prospective study was conducted on 290 postoperative early-stage breast cancer patients (response rate 96.7%) in China. Depression and anxiety status before adjuvant chemotherapy were assessed by the Hospital Anxiety and Depression Scale (HADS). Adverse events that occurred throughout the course of chemotherapy were graded and recorded according to Common Terminology Criteria for Adverse Events (CTCAE) 4.02. The rates of depression and anxiety were 20.0% and 31.4%, respectively, at baseline. The incidence of grade two or higher myelosuppression induced by chemotherapy was correlated with depression before chemotherapy (p=0.037). Multivariate analysis showed that the incidence of myelosuppression was significantly related to depression before chemotherapy (p=0.032). There was no association between depression and anxiety status and other adverse events (p > 0.05). We observed an association between depression status in breast cancer patients receiving adjuvant chemotherapy and chemotherapy-induced myelosuppression. Monitoring the depression status of breast cancer patients before chemotherapy may help to optimize the management of adverse events.

An ensemble learning with active sampling to predict the prognosis of postoperative non-small cell lung cancer patients

BackgroundLung cancer is the leading cause of cancer death worldwide. Prognostic prediction plays a vital role in the decision-making process for postoperative non-small cell lung cancer (NSCLC) patients. However, the high imbalance ratio of prognostic data limits the development of effective prognostic prediction models.MethodsIn this study, we present a novel approach, namely ensemble learning with active sampling (ELAS), to tackle the imbalanced data problem in NSCLC prognostic prediction. ELAS first applies an active sampling mechanism to query the most informative samples to update the base classifier to give it a new perspective. This training process is repeated until no enough samples are queried. Next, an internal validation set is employed to evaluate the base classifiers, and the ones with the best performances are integrated as the ensemble model. Besides, we set up multiple initial training data seeds and internal validation sets to ensure the stability and generalization of the model.ResultsWe verified the effectiveness of the ELAS on a real clinical dataset containing 1848 postoperative NSCLC patients. Experimental results showed that the ELAS achieved the best averaged 0.736 AUROC value and 0.453 AUPRC value for 6 prognostic tasks and obtained significant improvements in comparison with the SVM, AdaBoost, Bagging, SMOTE and TomekLinks.ConclusionsWe conclude that the ELAS can effectively alleviate the imbalanced data problem in NSCLC prognostic prediction and demonstrates good potential for future postoperative NSCLC prognostic prediction.

A 5-year follow-up assessment of anxiety and depression in postoperative prostate cancer patients: longitudinal progression and prognostic value

ABSTRACT Anxiety and depression are prevalent in cancer patients and correlate with poor prognosis. Nevertheless, their clinical role in prostate cancer patients after tumor resection is limited. Thus, the present study aimed to explore the longitudinal progression of anxiety and depression, and their association with prognosis in these patients. Two hundred and sixty-two prostate cancer patients after tumor resection were enrolled. Hospital Anxiety and Depression Scale (HADS) for anxiety (HADS-A) and for depression (HADS-D), disease-free survival (DFS) and overall survival (OS) were documented during 5-year follow-up. HADS-A score (from 7.73 at baseline to 8.48 at 5 years, P = 0.002) and anxiety severity (P = 0.001) but not anxiety rate (from 37.8% at baseline to 45.4% at 5 years, P = 0.067) were gradually elevated with time. HADS-D score (from 7.43 at baseline to 8.37 at 5 years, P < 0.001), depression rate (from 34.0% at baseline to 46.9% at 5 years, P < 0.001) and depression severity (P < 0.001) were also obviously increased with time. Moreover, baseline, 1-year, 2-year, 3-year, 4-year and 5-year anxiety correlated with worse DFS and OS (all P < 0.05, except for 2-year anxiety with OS: P = 0.126). In addition, baseline, 1-year, 2-year, 3-year, 4-year and 5-year depression associated with worse DFS (all P < 0.05); while only baseline, 1-year, 2-year depression related to worse OS (all P < 0.05). In conclusion, anxiety and depression continuously aggravate, and associate with poor prognosis in prostate cancer patients after tumor resection, indicating the necessity of proper management of anxiety and depression in these patients.

Alterations of posterior pharyngeal wall movement during swallowing in postoperative tongue cancer patients: assessment with a videofluoroscopic swallowing study.

This study aimed to determine the association between the progressive contraction of the posterior pharyngeal wall and dysphagia in postoperative patients with tongue cancer. A videofluoroscopic swallowing study (VFSS) was performed in 34 patients after tongue cancer surgery. Images were analyzed using a two-dimensional video measurement software. Cases in which the processes on the posterior pharyngeal wall moved downward from the 2nd to 4th vertebral regions were defined as "normal type", other cases were defined as "abnormal type". Twenty-four patients showed normal movement of the posterior pharyngeal wall, whereas 10 patients showed the abnormal type. The results showed that there was a significant difference in dysphagia scores between the postoperative swallowing type and swallowing dysfunction score. This implies that dysphagia is related to the movement of the posterior pharyngeal wall after tongue cancer surgery. Furthermore, the extent of resection and stage were significantly different between the normal and abnormal groups in the posterior pharyngeal wall movement. There was also a significant difference between the two groups in terms of the following: whether the tongue base was included in the excision range (p < 0.01), whether neck dissection was performed (p < 0.01), or whether reconstruction was not performed (p < 0.01). VFSS results showed that posterior pharyngeal wall movement was altered after surgery in patients with tongue cancer who had severe dysphagia.

Preoperative evaluation of oral hygiene may predict the overall survival of patients with esophageal cancer.

Previously, the association between tooth loss and prognosis after esophagectomy was reported; however, the presence of periodontal disease has not been assessed. This study investigated the association between the degree of oral hygiene, as evaluated by tooth loss and periodontal disease, and the prognosis of patients with esophageal cancer. A total of 163 esophageal cancer patients who underwent surgery with perioperative oral care and examination were enrolled. We assessed the periodontal pocket depth for the presence of periodontal disease and established a periodontal pocket index, defined as the sum of the periodontal pocket depth of the remaining tooth divided by the total count of the remaining teeth. Patients were divided into three groups: Group A (tooth loss < 13 and periodontal pocket index < 3.67); Group B (tooth loss < 13 and periodontal pocket index ≥ 3.67); and Group C (tooth loss ≥ 13). Overall survival and cancer-specific survival were analyzed, and a multivariate analysis was performed. There was a significant difference in the 5-year overall survival rates between the groups (A:B:C = 74.8%:62.8%:50.5%; p = 0.0098), but not in the 5-year cancer-specific survival rates (A:B:C = 80.2%:64.2%:62.2%; p = 0.0849). In multivariate analysis, oral hygiene (tooth loss < 13 and periodontal pocket index ≥ 3.67 + tooth loss ≥ 13; p = 0.041) was a significant independent poor prognostic factor for overall survival. Oral evaluation, focusing on tooth loss and periodontal disease, is meaningful in predicting the long-term prognosis of postoperative esophageal cancer patients.

Variation of Anxiety and Depression During a 3-Year Period as Well as Their Risk Factors and Prognostic Value in Postoperative Bladder Cancer Patients

BackgroundAnxiety and depression are commonly recognized and prognostically relevant in cancer patients. The aim of this study was to explore the 3-year longitudinal changes in anxiety and depression, their risk factors, and prognostic value in patients with bladder cancer.MethodsHospital Anxiety and Depression Scale for anxiety (HADS-A) and depression (HADS-D) scores of 120 postoperative bladder cancer patients and 100 healthy controls (HCs) were assessed. Additionally, the HADS-A and HADS-D scores of bladder cancer patients were determined at 1 year, 2 years, and 3 years post surgery.ResultsHADS-A score (7.7 ± 3.0 vs. 4.8 ± 2.6), anxiety rate (38.3% vs. 9.0%), HADS-D score (7.7 ± 3.3 vs. 4.3 ± 2.6), depression rate (40.0% vs. 11.0%), as well as anxiety degree and depression degree, were all increased in bladder cancer patients compared with HCs (all P < 0.001). Besides, the HADS-A score gradually increased from baseline to 3 years (P = 0.004), while the anxiety rate, HADS-D score, and depression rate did not change significantly (all P > 0.050). Gender, tumor size, marriage status, hypertension, diversity, and lymph node (LN) metastasis were associated with anxiety or depression in patients with bladder cancer (all P < 0.050). Anxiety was associated with shortened overall survival (OS) (P = 0.024) but did not link with disease-free survival (DFS) (P = 0.201); depression was not correlated with either DFS or OS (both P > 0.050).ConclusionThe prevalence and severity of anxiety and depression are high in patients with bladder cancer, which are influenced by gender, tumor features, marriage status, and hypertension; in addition, their correlation with survival is relatively weak.

The Effect of Pilates Exercise Nursing Combined with Communication Standard-Reaching Theory Nursing and Pelvic Floor Muscle Training on Bladder Function and Family Function of Patients after Cervical Cancer Surgery.

Objective To explore the effect of Pilates exercise nursing combined with nursing based on the theory of communication compliance and pelvic floor muscle training on bladder function and family function of patients after cervical cancer surgery. Methods The medical records of 96 postoperative cervical cancer patients treated in our hospital from November 2019 to May 2021 were selected as retrospective research objects and were divided into observation group and control group with 48 cases each according to the digital table method. The control group received nursing care based on the theory of communication compliance and pelvic floor muscle training, and the observation group received Pilates exercise therapy nursing on the basis of the control group. The differences in urinary retention, family intimacy and adaptability, bladder function, and family function evaluation scores were compared between the two groups. Results After nursing, the residual urine volume, urination time, and urination interval of the observation group were lower than those of the control group, while the self-resolving urination rate and urination volume of the observation group were higher than those of the control group, which was statistically significant (P < 0.05). Before nursing, the family intimacy and adaptability scores of the two groups of patients were not statistically significant (P > 0.05). After nursing, the family intimacy score, family adaptability score, and sexual function score of the observation group were significantly higher than the control group; the comparison was statistically significant (P < 0.05). After nursing, the bladder function recovery of the observation group was significantly better than that of the control group, which was statistically significant (P < 0.05). Before nursing, the comparison of family function evaluation between the two groups of patients was not statistically significant (P > 0.05). After nursing, the observation group's problem solving, communication, role, emotional response, emotional intervention, behavior control, and total functional scores were lower than those of the control group, which were statistically significant (P < 0.05). Conclusion Carrying out nursing care based on the theory of communication compliance with Pilates exercise therapy for patients after cervical cancer surgery has a good nursing effect improves the patient's family intimacy and adaptability and patient's urinary retention and bladder function. Moreover, Pilates exercise nursing is a postoperative treatment for cervical cancer which provides a certain reference for clinical care of patients.

Effects of Traditional Chinese Medicine Anticancer Decoction Combined with Basic Chemotherapy and Nursing Intervention on Oral Cancer Patients after Surgery and Its Effect on Tumor Markers and Immune Function.

Objective To prospectively study the application effect of traditional Chinese medicine (TCM) anticancer decoction with basic chemotherapy and nursing intervention on oral cancer patients after surgery and the effect on tumor markers and immune function. Methods Eighty-four postoperative oral cancer patients in our hospital from May 2017 to February 2019 were selected and divided into observation group (42 cases) and control group (42 cases). The control group was treated with basic chemotherapy combined with basic nursing care, and the observation group was treated with TCM anticancer decoction and comprehensive nursing intervention on the basis of the control group. The clinical efficacy, the occurrence of adverse reactions, the satisfaction of nursing care, and the two-year cumulative survival rate of the two groups were compared. The immune function, tumor marker level, VAS score, QoR40 score, and survival quality score of the two groups were compared before and after nursing care. Results The total clinical treatment efficiency of the observation group (88.10%) was significantly higher than that of the control group (69.05%), and the differences between the two groups in oral cleanliness, aspiration frequency, and oral comfort were statistically significant (P < 0.05). The differences in the occurrence of halitosis, oral fungal infection, leukopenia, gastrointestinal reaction, and fever in the observation group were statistically significant compared with the control group (P < 0.05). The nursing satisfaction rate in the observation group (95.24%) was significantly higher than that in the control group (78.57%). The two-year cumulative survival rate of the observation group (92.86%) was significantly higher than that of the control group (73.81%). After nursing care, CD4+, CD4+/CD8+, VAS scores, QoR40 scores, and quality of survival scores in both groups all increased, and CD8+, CD56+, CEA level, NSE level, and CA19-9 level all decreased (all P < 0.05). Conclusion The clinical efficacy of TCM anticancer decoction with basic chemotherapy and nursing interventions in the treatment of postoperative oral cancer patients was remarkable, which could significantly improve patients' oral cleanliness and comfort, reduce the frequency of sputum aspiration, improve patients' immunity, reduce tumor marker levels, inhibit tumor activity, improve patients' nursing satisfaction, further improve patients' treatment compliance, reduce patients' pain level, improve patients' survival quality, and prolong patients' survival time with high safety. It could be used as a theoretical basis for subsequent clinical research.

Stigma and related influencing factors in postoperative oral cancer patients in China: a cross-sectional study.

To examine the level of stigma and identify its influencing factors among postoperative oral cancer patients in China. In total, 274 postoperative oral cancer patients were recruited from a Grade A Tertiary Hospital in China using convenience sampling methods. Patients completed the Social Impact Scale (SIS), Medical Coping Mode Questionnaire (MCMQ), Social Support Rating Scale (SSRS), and General Self-efficacy Scale (GSE). Stigma reported by postoperative oral cancer patients was moderate (50.17 ± 21.24). Stepped multiple linear regression showed that the related factors influencing their feelings of stigma were educational level (β = - 0.110, P = 0.001), smoking (β = - 0.152, P < 0.001), betel quid (β = - 0.120, P = 0.001), tumor location (β = - 0.390, P < 0.001), tumor stage (β = 0.219, P < 0.001), self-efficacy (β = - 0.253, P < 0.001), and confrontation (β = - 0.117, P = 0.001) and avoidance (β = 0.123, P < 0.001), which explained 74.2% of the total variation in stigma (F = 99.378, P < 0.001). Stigma was positively predicted by tumor stage and avoidance but negatively predicted by education level, smoking, betel quid, tumor location, confrontation, and self-efficacy. Further work should focus on developing interventions to reduce stigma by improving protective factors and decreasing risk factors.

Upregulation of PODXL and ITGB1 in pancreatic cancer tissues preoperatively obtained by EUS-FNAB correlates with unfavorable prognosis of postoperative pancreatic cancer patients.

The upregulation of PODXL and ITGB1 in surgically resected pancreatic cancer tissues is correlated with an unfavorable postoperative prognosis. The aim of this study was to investigate whether PODXL and ITGB1 are useful preoperative markers for the prognosis of postoperative pancreatic cancer patients in comparison with the TNM staging system. Immunohistochemistry was performed using anti-PODXL and anti-ITGB1 antibodies on 24 pancreatic cancer tissue samples preoperatively obtained by endoscopic ultrasound-guided fine-needle aspiration biopsy. Cox proportional hazards regression analysis was performed to investigate if the UICC TNM stage and upregulation of PODXL and ITGB1 were correlated with postoperative overall survival rates. Univariate analysis revealed that PODXL, TNM stage, lymphatic invasion and the combination of PODXL with ITGB1 are correlated with postoperative survival. Multivariate analysis demonstrated TNM stage and the combination of PODXL with ITGB1 to be correlated with postoperative survival, and the combination of PODXL with ITGB1 most accurately predicted the postoperative outcomes of pancreatic cancer patients before resection. Therefore, upregulation of PODXL and ITGB1 may indicate preoperative neoadjuvant therapy for pancreatic cancer patients by accurately predicting the postoperative prognosis.

Randomized Clinical Trial: Probiotics Alleviated Oral-Gut Microbiota Dysbiosis and Thyroid Hormone Withdrawal-Related Complications in Thyroid Cancer Patients Before Radioiodine Therapy Following Thyroidectomy.

BackgroundThyroid hormone withdrawal (THW) in postoperative thyroid cancer patients who need always accompanied by complications (e.g., dyslipidemia and constipation). At present, there are no effective and safe means to alleviate these complications.PurposeWe aimed to assess the oral-gut microbiota profiles in THW patients then investigate whether probiotics could alleviating alleviate THW related complications and investigate whether these therapeutic effects were associated with the oral-gut microbiota state.MethodsFifty eligible thyroid carcinoma patients undergoing thyroidectomy were randomly assigned to receive probiotics or placebo during THW. Complications were assessed through validated questionnaires and plasma lipid indicators. The complex probiotics preparation was composed of Bifidobacterium infantis, Lactobacillus acidophilus, Enterococcus faecalis, and Bacillus cereus.ResultsProbiotics alleviated lack of energy, constipation, weight gain, and dry mouth and decreased the levels of fecal/serum LPS and plasma lipid indicators (total cholesterol, triglycerides, low-density lipoprotein, and apolipoprotein A) (P < 0.05). Gut and oral microbial diversity were significantly decreased after THW, while an increased microbial dysbiosis index (MDI) was observed. Probiotics distinctly restored the gut and oral microbial diversity. Increased Holdemanella, Enterococcus, and Coprococcus_2, while decreased Fusobacterium, Eubacterium_ruminantium_group, Ruminococcus_1, and Parasutterella in the gut were found after probiotics intervention. Lack of energy, constipation, weight gain, and dyslipidemia were seen to be related to the above microbiota. In addition, probiotics reduced oral Prevotella_9, Haemophilus, Fusobacterium, and Lautropia, which were positively correlated with the occurrence of dry mouth.ConclusionProbiotics reduce the incidence of complications in patients after THW, which may be related to modifying the oral and gut microbiota.Clinical Trial Registration[https://clinicaltrials.gov/], identifier America Clinical Trial Registry NCT03574051.

Polydopamine-coated nanocomposite theranostic implants for localized chemotherapy and MRI imaging

Sustained and localized delivery of chemotherapeutics in postoperative cancer treatment leads to a radical improvement in prognosis and a much decreased risk of tumor recurrence. In this work, polydopamine (PDA)-coated superparamagnetic iron oxide nanoparticle (SPION)-loaded polycaprolactone and poly(lactic-co-glycolic acid) fibers were developed as a potential implant to ensure safe and sustained release of the chemotherapeutic drug methotrexate (MTX), as well as provide local contrast for magnetic resonance imaging (MRI). Fibres were prepared by co-axial electrospinning and loaded with MTX-layered double hydroxide (LDH) nanocomposites in the core, yielding organic–inorganic hybrids ranging from 1.23 to 1.48 µm in diameter. After surface coating with PDA, SPIONs were subsequently loaded on the fibre surface and found to be evenly distributed, providing high MRI contrast. In vitro drug release studies showed the PDA coated fibres gave sustained release of MTX over 18 days, and the release profile is responsive to conditions representative of the tumor microenvironment such as slightly acidic pH values or elevated concentrations of the reducing agent glutathione (GSH). In vitro studies with Caco-2 and A549 cells showed highly effective killing with the PDA coated formulations, which was further enhanced at higher levels of GSH. The fibres hence have the potential to act as an implantable drug-eluting platform for the sustained release of cytotoxic agents within a tumor site, providing a novel treatment option for post-operative cancer patients.

Effects of Mobile Healthcare Applications on the Lifestyle of Patients With Breast Cancer: A Protocol for a Randomized Clinical Trial.

Physical activity (PA) in patients with breast cancer is associated with improved quality of life (QoL); however, many breast cancer survivors do not meet the recommended PA level. This study aims to evaluate the effect of digital health interventions using mobile apps to promote PA and QoL in patients with postoperative breast cancer. This study will also identify effective digital intervention methods and perform an economic analysis. The main hypothesis is that the use of mobile healthcare apps will improve health-related quality of life (HRQOL), promote PA, and reduce healthcare costs. The Promotion of a better lifestyle (PA) with Precise and Practicable digital healthcare in postoperative CANCER patients through a Multi-Disciplinary Network (P4CancerMDnet) study is examined by a prospective 4-group randomized controlled trial with a concurrent cost-utility evaluation. Patients are randomly assigned to 3 different mobile app intervention groups or control groups in a 1:1:1:1 ratio. The intervention group is encouraged to use the assigned mobile app. The targeted outcomes are HRQOL, metabolic health markers, and quality-adjusted life-years. The outcomes will be measured at the 6- and 12-month follow-ups. This study will contribute towards a better lifestyle and HRQOL through digital healthcare for postoperative breast cancer patients. These findings are expected to provide evidence of the effectiveness of mobile apps for breast cancer survivors. Clinical Research Information Service Identifier: KCT0005447.

Correlation analysis of body image level and female sexual dysfunction in young patients with postoperative breast cancer

To determine the relationship between female body image and female sexual dysfunction (FSD) in young patients (20-40 years) with postoperative breast cancer. Using the convenient sampling method, we identified 276 young patients with postoperative breast cancer from June 2017 to 2019 in the Department of Oncology and Radiotherapy of the First Affiliated Hospital of Anhui Medical University to be included in the study. A general situation questionnaire for body image scale (BIS) and female sexual function index (FSFI) scale was used to evaluate the correlation between body image level and the prevalence of FSD in young patients with postoperative breast cancer. The total score for BIS was 10.98 ± 7.19, indicating that patients were moderately dissatisfied with their body image The total prevalence of FSD was 63.41%. Pearson correlation analysis showed a negative correlation between the total score, each dimension score of BIS, total FSD, and the incidence of each dimension disorder (range, r: -0.414 to -0.717, all P values <0.05). There is a negative correlation between the body image level and the prevalence of FSD in young patients with postoperative breast cancer. This suggests that clinical medical workers should develop an intervention plan to improve the body image level of postoperative young breast cancer patients according to the unique physiological and psychological characteristics of these patients while also reducing the prevalence of FSD.

Machine Learning-Based Model for the Prognosis of Postoperative Gastric Cancer.

BackgroundThe use of machine learning (ML) in predicting disease prognosis has increased, and scientists have adopted different methods for cancer classification to optimize the early screening of cancer to determine its prognosis in advance. In this study, we aimed at improving the prediction accuracy of gastric cancer in postoperation patients by constructing a highly effective prognostic model.MethodsThe study used postoperative gastric cancer patient data from the SEER database. The LASSO regression method was used to construct a clinical prognostic model, and four machine learning methods (Boruta algorithm, neural network, support vector machine, and random forest) were used to screen and recombine the features to construct an ML prognostic model. Clinical information on 955 postoperative gastric cancer patients collected from the Affiliated Tumor Hospital of Harbin Medical University was used for external verification.ResultsExperimental results showed that the AUC values of 1, 3 and 5 years in the training set, validation set and external validation set of clinical prognosis model and ML prognosis model directly established by LASSO regression are all around 0.8.ConclusionBoth models can accurately evaluate the prognosis of postoperative patients with gastric cancer, which may be helpful for accurate and personalized treatment of postoperative patients with gastric cancer.

Clinical Significance of Preoperative Naples Prognostic Score in Patients With Non-Small Cell Lung Cancer.

Background: Naples Prognostic Score (NPS) is a novel score based on inflammatory-nutritional indicators. We aimed to analyze the prognostic value of the Naples Prognostic Score in non-small cell lung cancer (NSCLC) patients following surgery. Methods: A total of 319 NSCLCpatients following surgery were analyzed in the retrospective cohort study. We analyzed the predictive value of Naples Prognostic Score for overall survival and recurrence-free survival in postoperative non-small cell lung cancer patients by using Kaplan-Meier survival curves and multivariate Cox regression analysis. At the same time, the time-dependent ROC and the area under curves were also created to compare the accuracy of different scoring systems. Results: According to NPS, we divided all patients into 3 groups，120 patients were divided into group 0, 161 patients were divided into group 1, and 38 patients were divided into group 2. The median survival time for all patients is 32 months, and the median survival times for different groups were 35 months, 31 months, and 28 months, respectively. The overall survival and recurrence-free survival survival curves of different groups were significantly different (both P < .05), and patients in the higher NPS groups had a disappointing prognosis. NPS may be an independent prognostic factor for overall survival and recurrence-free survival, according to the results of multivariate analysis (both P < .05). The area under curve showed that the accuracy of the NPS was significantly better than other score systems. Conclusions: The NPS is closely related to the long-term survival prognosis of patients with NSCLC, especially in stage III patients.

The magnitude of increased Levothyroxine dose during pregnancy in patients on thyroid-stimulating hormone (TSH) suppression treatment after total thyroidectomy for papillary carcinoma.

The dose of L-T4 replacement for hypothyroidism often needs to be increased after pregnancy. In our institution, patients are instructed to double the dose 2 days a week after pregnancy. However, there is scarce evidence supporting the need for a dose increase after pregnancy in patients with preconception thyroid-stimulating hormone (TSH) suppression (TSH <0.3 μIU/mL). This study aimed to determine the need for a dose increase in L-T4 among women with a TSH-suppressive dose of L-T4 before pregnancy. In this retrospective observational study, between January 2008 and December 2018, we analyzed 166 pregnancies in 134 patients on TSH suppression treatment after total thyroidectomy for papillary carcinoma. Thyroid function tests were performed before and in the first trimester of pregnancy. The dose was adjusted and maintained during the first trimester of pregnancy in 76 pregnancies (group A) and 90 pregnancies (group B), respectively. The median serum TSH level was significantly lower in group A than that in group B (0.014 μIU/mL (IQR, 0.005-0.071) vs. 0.155 μIU/mL (IQR, 0.021-0.657), p < 0.001). TSH suppression could not be maintained after pregnancy in 15.8% and 38.9% of the pregnancies in groups A and B, respectively. Increasing the post-pregnancy dose by an average of 27.4% resulted in maintenance of TSH suppression after pregnancy in 84.2% of pregnancies. In conclusion, this study suggests that increasing the L-T4 dose after pregnancy may be appropriate in postoperative thyroid cancer patients whose serum TSH levels should be suppressed.
