Factors associated with perceived cognitive function in breast cancer patients treated with chemotherapy: A multicenter cross-sectional study.

PURPOSE: This study aimed to investigate the factors associated with perceived cognitive function among breast cancer patients treated with chemotherapy in China. METHODS: The study was a multicenter cross-sectional design. Data were collected from 10 public hospitals in China between April 2022 and February 2023. A total of 741 participants completed questionnaires assessing sociodemographic and medical characteristics, perceived cognitive function, sleep quality, fatigue, anxiety, and depression. Hierarchical multiple regression analysis was used to assess the determinants of cognitive function. RESULTS: The hierarchical multiple regression model accounted for 31.5% of variation in perceived cognitive function (sociodemographic 4.5%; medical 6.6%; exercise frequency 6.6%; sleep quality 2.1%; fatigue 2.8%; anxiety combined with depression 9.0%). Education level, chemotherapy type, number of chemotherapy cycles, and cyclophosphamide drug use were significant predisposing factors of perceived cognitive function (p < 0.001). Exercising ≥3 times/week (p < 0.001) was a significant factor positively influencing perceived cognitive function, meanwhile, anxiety (p < 0.001) and depression (p < 0 0.001) were negative factors. CONCLUSION: Our findings suggest that patients with low education levels, postoperative chemotherapy, cyclophosphamide treatment, and a greater number of chemotherapy cycles need more assessment. Sedentary patients, those who have never exercised, and those with anxiety or depression all showed greater cognitive decline. By identifying susceptible populations, encouraging regular exercise, and addressing anxiety and depression, healthcare professionals can contribute significantly to prevent patients' cognitive decline throughout chemotherapy.

A case of fat-forming solitary fibrous tumor that is prone to be confused with liposarcoma.

Fat-forming solitary fibrous tumor is a rare and specific subtype of solitary fibrous tumor. In this case, a mass of 8.3 cm in diameter was found in a 59-year-old male patient's right retroperitoneum, as revealed by abdominal contrast-enhanced computed tomography (CT) images. The tumor exhibited a well-circumscribed nature and histological features characterized by a combination of hemangiopericytomatous vasculature and mature adipose tissue, comprising around 70% of the total tumor composition. Immunohistochemistry staining revealed diffuse positive expression of STAT6 and CD34 in the tumor cells. Based on these findings, the final diagnosis was determined to be a fat-forming solitary fibrous tumor located in the retroperitoneum. It is important to consider other potential differential diagnoses, including angiomyolipoma, dedifferentiated liposarcoma, spindle cell lipoma, and atypical lipomatous tumor/well-differentiated liposarcoma.

Ki-67 Change in Anthracyline-containing Neoadjuvant Chemotherapy Response in Breast Cancer.

OBJECTIVE: Anthracycline-containing regimens are irreplaceable in neoadjuvant chemotherapy (NAC) for breast cancer (BC) at present. However, 30% of early breast cancer (EBC) patients are resistant to anthracycline-containing chemotherapy, leading to poor prognosis and higher mortality. Ki-67 is associated with the prognosis and response to therapy, and it changes after NAC. METHODS: A total of 105 BC patients who received anthracycline-containing NAC were enrolled. Then, the optimal model of Ki-67 was selected, and its predictive efficacy was analyzed. Immunohistochemistry (IHC) was used to determine the estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER-2) status and Ki-67 level. Fluorescent in situ hybridization (FISH) was used to verify the HER-2 when the IHC score was 2+. RESULTS: The post-NAC Ki67 level after treatment with anthracycline drugs was lower than pre-NAC Ki-67 (19.6%±23.3% vs. 45.6%±23.1%, P<0.001). Furthermore, patients with the Ki-67 decrease had a border line higher pathological complete response (pCR) rate (17.2% vs. 0.0%, P=0.068), and a higher overall response rate (ORR) (73.6% vs. 27.8%, P<0.001), when compared to patients without the Ki-67 decrease. The ΔKi-67 and ΔKi-67% were valuable markers for the prediction of both the pCR rate and ORR. The area under the curve (AUC) for ΔKi-67 on pCR and ORR was 0.809 (0.698-0.921) and 0.755 (0.655-0.855), respectively, while the AUC for ΔKi-67% on pCR and ORR was 0.857 (0.742-0.972) and 0.720 (0.618-0.822), respectively. Multivariate logistic regression model 1 revealed that ΔKi-67 was an independent predictor for both pCR [odds ratio (OR)=61.030, 95% confidence interval (CI)=4.709-790.965; P=0.002] and ORR (OR=10.001, 95% CI: 3.044-32.858; P<0.001). Multivariate logistic regression model 2 revealed that ΔKi-67% was also an independent predictor for both pCR (OR=408.922, 95% CI=8.908-18771.224; P=0.002) and ORR (OR=5.419, 95% CI=1.842-15.943; P=0.002). CONCLUSIONS: The present study results suggest that ΔKi67 and ΔKi67% are candidate predictors for anthracycline-containing NAC response, and that they may provide various information for further systematic therapy after surgery in clinical practice.

Mesenchymal Stem Cell Therapy for Patients with Ischemic Heart Failure- Past, Present, and Future.

The prevalence of Heart Failure (HF) has increased over time. Ischemic heart failure accounts for 50% of HF, which results from ischemic coronary heart diseases such as Myocardial Infarction (MI). Conventionally, reduction of cardiac load and revascularization partially increase cardiomyocyte survival and preserve cardiac functions. Nevertheless, how to improve cardiomyocyte rescue and prevent HF progression remain as challenges. Mesenchymal Stem Cells (MSCs) are multipotent stem cells that give rise to various lineages. The administration of MSCs promotes cardiomyocyte survival and improves cardiac functions in animal models of MI and patients with ischemic cardiomyopathy. However, after injection, MSCs persist for a very short time, indicating that the prolonged protective effects of MSCs on cardiomyocytes may be mediated by paracrine functions of MSCs, such as exosomes. In this review, we focus on MSC-derived exosomes in cardiomyocyte protection to facilitate future applications of exosomes in HF treatment.

Complete remission of heavily treated ovarian clear cell carcinoma with ARID1A mutations after pembrolizumab and bevacizumab combination therapy: a case report.

BACKGROUND: Patients with ovarian clear cell carcinoma (OCCC) have a poor prognosis because they show low sensitivity to platinum-based chemotherapy. New treatments for refractory OCCC are urgently needed. CASE PRESENTATION: We present a patient with refractory OCCC in whom conventional chemotherapy failed. Cachexia was induced by the disseminating recurrent tumors. Tumor tissue staining and genomic analysis revealed PD-L1 negativity, a low tumor burden, stable microsatellite instability, and two mutations in ARID1A. The patient was administered pembrolizumab combined with bevacizumab triweekly. Her serum CA-125 level decreased dramatically after the first cycle. A computerized tomography scan showed marked regression of the recurrent masses after 3 cycles, and the patient reached complete remission after 9 cycles. She showed good recovery from cachexia. We observed no marked side effects except for mild polyarthritis of the small joints. CONCLUSIONS: The therapeutic effect of checkpoint inhibitors combined with angiogenesis inhibitors is very promising in our patient with OCCC. Further clinical trials of tumors including ARID1A mutations are warranted.

Neoadjuvant metformin added to conventional chemotherapy synergizes anti-proliferative effects in ovarian cancer.

BACKGROUND: Ovarian cancer is the leading cause of cancer-related death among women. Complete cytoreductive surgery followed by platinum-taxene chemotherapy has been the gold standard for a long time. Various compounds have been assessed in an attempt to combine them with conventional chemotherapy to improve survival rates or even overcome chemoresistance. Many studies have shown that an antidiabetic drug, metformin, has cytotoxic activity in different cancer models. However, the synergism of metformin as a neoadjuvant formula plus chemotherapy in clinical trials and basic studies remains unclear for ovarian cancer. METHODS: We applied two clinical databases to survey metformin use and ovarian cancer survival rate. The Cancer Genome Atlas dataset, an L1000 microarray with Gene Set Enrichment Analysis (GSEA) analysis, Western blot analysis and an animal model were used to study the activity of the AKT/mTOR pathway in response to the synergistic effects of neoadjuvant metformin combined with chemotherapy. RESULTS: We found that ovarian cancer patients treated with metformin had significantly longer overall survival than patients treated without metformin. The protein profile induced by low- concentration metformin in ovarian cancer predominantly involved the AKT/mTOR pathway. In combination with chemotherapy, the neoadjuvant metformin protocol showed beneficial synergistic effects in vitro and in vivo. CONCLUSIONS: This study shows that neoadjuvant metformin at clinically relevant dosages is efficacious in treating ovarian cancer, and the results can be used to guide clinical trials.

Supporting her as the situation changes: A qualitative study of spousal support strategies for patients with breast cancer in China.

OBJECTIVE: Spouses who are the major source of social support for married breast cancer patients sometimes do not know how to support the patient effectively. This study aimed to investigate the experiences and strategies of spouses identified as supportive for patients throughout the disease. METHODS: A qualitative study using semi-structured in-depth interviews was conducted with 22 husbands of Chinese women with breast cancer, who had effectively supported their wives. Thematic analysis was used for data analysis. RESULTS: Three themes emerged from the data: (a) following the diagnosis, the spouse focused on "problem solving under stress" by preparing the patient for the physician's disclosure of the diagnosis, helping her to cope with the shock, and aiding her in dealing with the treatment recommendations; (b) during treatment, the spouse focused on "functional compensation" to offset the patient's reduced self-care and family care abilities; and (c) following treatment, the spouse focused on "role return" by adapting to changes in the patient and assisting her return to the family and society. CONCLUSION: Chinese spouses of women with breast cancer exhibited support strategies that varied with disease progress. Healthcare providers should aid spouses in providing support according to the changing needs of patients with breast cancer.

Clinical Efficacy and Safety of Combination Therapy with Amlodipine and Olmesartan or an Olmesartan/Hydrochlorothiazide Compound for Hypertension: A Prospective, Open-Label, and Multicenter Clinical Trial in China.

BACKGROUND: Amlodipine (AML) is the initial therapy most commonly prescribed for patients with hypertension in China. However, AML monotherapy is often less effective in achieving blood pressure (BP) control than other agents. OBJECTIVE: We performed a clinical study to evaluate efficacy and safety of a combination therapy with AML, olmesartan (OLM), or an OLM/hydrochlorothiazide (HCTZ) compound for Chinese patients with mild-to-moderate hypertension. METHODS: In the clinical trial, patients were initially treated with OLM 20 mg/d combined with AML 5 mg/d. Then OLM was uptitrated to 40 mg/d or changed to an OLM/HCTZ (20/12.5 mg/d) compound if the patients did not reach the target of seated diastolic BP <90 mm Hg (<80 mm Hg in patients with diabetes) after 8 weeks. RESULTS: The overall response rate of the combination therapy was 59.2% (95% CI, 54.23%-63.97%) at Week 2 and gradually increased to 97.1% (95% CI, 94.93%-98.47%) at the end of the study (Week 16). CONCLUSIONS: The combination therapy with OLM or OLM/HCTZ was well tolerated. The total incidence of adverse events was 42.9% (n = 176). Most of the adverse events were mild in severity (39.5%; n = 162) and not associated with the drugs (33.2%). In conclusion, combination therapy with AML, OLM, or OLM/HCTZ can significantly lower BP safely and achieve a high BP control rate in patients with mild-to-moderate hypertension in China.

Identifying occult maternal malignancies from 1.93 million pregnant women undergoing noninvasive prenatal screening tests.

PURPOSE: Multiple chromosomal aneuploidies may be associated with maternal malignancies and can cause failure of noninvasive prenatal screening (NIPS) tests. However, multiple chromosomal aneuploidies show poor specificity and selectivity for diagnosing maternal malignancies. METHODS: This multicenter retrospective analysis evaluated 639 pregnant women who tested positive for multiple chromosomal aneuploidies on initial NIPS test between January 2016 and December 2017. Women were assessed using genome profiling of copy-number variations, which was translated to cancer risk using a novel bioinformatics algorithm called the cancer detection pipeline (CDP). Sensitivity, specificity, and positive predictive value (PPV) of diagnosing maternal malignancies were compared for multiple chromosomal aneuploidies, the CDP model, and the combination of CDP and plasma tumor markers. RESULTS: Of the 639 subjects, 41 maternal malignant cancer cases were diagnosed. Multiple chromosomal aneuploidies predicted maternal malignancies with a PPV of 7.6%. Application of the CDP algorithm to women with multiple chromosomal aneuploidies allowed 34 of the 41 (83%) cancer cases to be identified, while excluding 422 of 501 (84.2%) of the false positive cases. Combining the CDP with plasma tumor marker testing gave PPV of 75.0%. CONCLUSION: The CDP algorithm can diagnose occult maternal malignancies with a reasonable PPV in multiple chromosomal aneuploidies-positive pregnant women in NIPS tests. This performance can be further improved by incorporating findings for plasma tumor markers.

Crosstalk between SOX2 and cytokine signaling in endometrial carcinoma.

Endometrial carcinoma is a cancer derived from oncogenesis of the regenerating uterine cavity, in which cytokine stimulation shapes cell differentiation and tissue remodeling. Expression of the stem cell factors SOX2, OCT4, NANOG, and MYC has been linked to tumor malignancy in several cancers. However, how these stem cell factors crosstalk with cytokine signaling to promote malignancy in endometrial carcinoma is still elusive. Here we report that the expression of SOX2 and MYC, but not that of OCT4 and NANOG, correlate with poor histological differentiation and prognosis, while SOX2 expression is negatively associated with MYC level. We found that SOX2-high endometrial carcinoma cells possessed a higher colony-forming ability than their SOX2-low counterparts, and knockdown of SOX2 attenuated the colony-forming ability. We observed that SOX2 regulated EGFR expression in a SOX2-EGFR positive feedback loop. EGF stimulation induced SOX2 expression and promoted migration of endometrial carcinoma cells, whereas TGF-ß stimulation inhibited SOX2 expression and attenuated the colony-forming ability. Immunohistochemistry analysis revealed that SOX2 expression correlated with lymph node infiltration of endometrial carcinoma. Our findings support that cytokine-induced stem cell factor SOX2 possesses oncogenic properties, with the potential to serve as a prognostic biomarker in endometrial carcinoma.

Copy number variation profile in noninvasive prenatal testing (NIPT) can identify co-existing maternal malignancies: Case reports and a literature review.

OBJECTIVE: The coexistence of maternal malignancy and pregnancy has received increasing attention in Noninvasive prenatal testing (NIPT) studies. Malignancy in pregnant women potentially affects the copy number variation (CNV) profile in NIPT results. Only one case of hematologic cancer has been reported in a Hong-Kong pregnant women, and solid tumors have never been reported in pregnant Chinese women. CASE REPORT: The patients with dysgerminoma and cervical cancer showed aberrant chromosomal aneuploidies in NIPT and concordant patterns of genome disruption in tumor tissues. The genomic aberrations in the gastric cancer patient had similar copy number variation pattern of gastric cancer. CONCLUSION: The findings in this study and the literature review further validate the effect of maternal malignancy on the copy number variation profile in NIPT data and strengthen the possibility of detecting malignant tumors with NIPT in the future.

The role of α2,3-linked sialylation on clear cell type epithelial ovarian cancer.

OBJECTIVE: Our previous study has shown that high expression of α2,3-sialytransferase type I was associated with advanced stage serous type epithelial ovarian cancer (EOC). The aim of the current study further attempts to evaluate the altered α 2,3-sialylation on the behavior of clear cell type EOC (C-EOC). MATERIALS AND METHODS: Immunohistochemistry staining, bioinformatics analysis and tissue array were used to disclose the clinical significance of over α2,3-sialylation in C-EOC. An α2,3 sialylation inhibitor, soyasaponin I (SsaI) was used to investigate the behavior change of the C-EOC cell line. RESULTS: We reconfirmed that α2,3-sialylation, instead of α2,6- sialylation, was associated with late-stage C-EOC. Soyasaponin I could inhibit α2,3-sialylation of C-EOC cell lines and increase E-cadherin expression with subsequently suppressing migration of C-EOC cells. CONCLUSIONS: The current study demonstrated the important role of α2,3-linked sialylation in C-EOC and targeting of α2,3-linked sialylation might offer as a potential therapeutic strategy in the future.

A case-control study to compare the outcome of women treated by two minimally invasive procedures-ultraminilaparotomy myomectomy and laparoscopic myomectomy.

OBJECTIVE: Ultraminilaparotomy myomectomy (UMLT-M with less 4 cm transverse skin incision) and conventional 3-port wound laparoscopic myomectomy (LM) approaches were proposed as alternative minimally invasive procedures in the management of women with symptomatic uterine myomas but few studies have compared the outcomes of both procedures. MATERIALS AND METHODS: Between January 2002 and December 2003, 71 patients undergoing UMLT-M were compared with those 71 women undergoing LM. The last data collection for all patients was done on 31 December 2016. The parameters for comparison included the characteristics of the uterine myomas, surgical parameters, morbidities, and outcomes. Surgical parameters included the operative time (minutes), estimated blood loss (milliliters), time for removal of drainage, percentage of blood transfusion and co-morbidities. RESULTS: Mean operative time in the LM group was significantly longer than that in the UMLT-M group (208.7 ± 65.9 vs. 98.0 ± 28.2 min, p < 0.001). Intra-operative blood loss was significantly higher in the LM group than that in the UMLT-M group (210.9 ± 184.5 vs. 111.7 ± 108.4 ml, p < 0.001). However, more patients had postoperative fever in the UMLT-M group (39.4% vs. 8.5%, p < 0.001). The recurrence rate of myoma at 5-year follow-up was significantly different between two groups (35.2% of UMLT-M vs. 57.7% of LM, p = 0.007), but there was no difference when follow-up time was over ten years. The location of the myoma recurrence was different between two groups with higher recurrence rates in the fundal and lateral sides of uterus in the UMLT-M group and in the anterior wall of uterus in the LM group. However, the overall symptom control, the need of repeated myoma-related surgery and subsequent pregnancy outcome of both groups seemed to be similar in both groups. CONCLUSIONS: More operative time and more blood loss reflected that LM demanded skills, experience and equipment. Therefore, UMLT-M might be a feasible alternative choice in the management of uterine myomas, since it is an easy-to-perform and familiar technique, especially in the absence of suitable equipment or skilled operator. A large and randomized study is needed to confirm the above findings.

The role of EpCAM in tumor progression and the clinical prognosis of endometrial carcinoma.

OBJECTIVE: EpCAM is a transmembrane glycoprotein that functions as an epithelial marker in endometrial tissues. However, the correlation between EpCAM and endometrial carcinoma (EC) is not clear. METHODS: This study investigated the association between EpCAM and EC. Immunohistochemistry staining and bioinformatics analysis disclosed the clinical importance of low EpCAM expression. The migratory ability of cells expressing low EpCAM levels was studied in transwell invasion assays in vitro and an orthotopic intra-uterine tumor injection model in vivo. The Connectivity MAP was used to identify drugs that effectively inhibit cells with low EpCAM expression. RESULTS: According to immunohistochemistry analysis results, low EpCAM expression was associated with an advanced stage and lymph node metastasis in patients with endometrioid EC, and high EpCAM expression favored survival. EpCAM silencing promoted cell invasion, and EpCAM re-expression in EpCAM-silenced EC cells attenuated their invasiveness. EpCAM suppression in an orthotopic uterine implantation model promoted the lymph node metastasis of EC cells. According to quantitative PCR and promoter reporter analyses, estrogen receptor alpha signaling regulated EpCAM expression by enhancing its promoter activity. As shown in the Connectivity MAP analysis, transamin inhibited the invasiveness of EpCAM-silenced EC cells. CONCLUSIONS: The loss of EpCAM may increase the malignancy of EC, and these findings provide new insights into the prognostic role of EpCAM in patients with EC.

The frequency of cancer predisposition gene mutations in hereditary breast and ovarian cancer patients in Taiwan: From BRCA1/2 to multi-gene panels.

An important role of genetic factors in the development of breast cancer (BC) or ovarian cancer (OC) in Taiwanese (ethnic Chinese) patients has been suggested. However, other than germline BRCA1 or BRCA2 mutations, which are related to hereditary breast-ovarian cancer (HBOC), cancer-predisposition genes have not been well studied in this population. The aim of the present study was to more accurately summarize the prevalence of genetic mutations in HBOC patients using various gene panels ranging in size from BRCA1/2 alone to multi-gene panels. Among 272 HBOC patients analyzed, the prevalence of BRCA1, BRCA2 and non-BRCA1/2 pathogenic mutations was 7.7% (21/272), 6.8% (16/236) and 8.2% (13/159), respectively. The total mutation rate was 18.4% (50/272). Although no founder mutations were identified in this study, two recurrent mutations, BRCA1 (c.3607C>T) and BRCA2 (c.5164_5165 delAG), were found. The main pathogenic/likely pathogenic mutations in non-BRCA1/2 genes included ATM, BRIP1, FANCI, MSH2, MUYTH, RAD50, RAD51C and TP53. The prevalence rate of gene mutations in HBOC patients did not differ with respect to whether BC or OC was the first diagnosis or they presented a family history of the disease or their age at diagnosis. HBOC patients with both BC and OC exhibited a higher prevalence rate of mutations (50.0%) than patients with OC (25.0%) or BC (8.6%) alone. In conclusion, evaluation of hereditary cancer risk in Taiwan HBOC patients, particularly individuals with double cancer, is strongly encouraged. Panel testing can yield additional genomic information, and widespread and well-designed panel testing will help in assessing more accurate mutational prevalence of risk genes.

α2,3-sialyltransferase type I regulates migration and peritoneal dissemination of ovarian cancer cells.

Epithelial ovarian cancer (EOC) has the highest mortality rate among gynecologic cancers due to advanced stage presentation, peritoneal dissemination, and refractory ascites at diagnosis. We investigated the role of α2,3-sialyltransferase type I (ST3GalI) by analyzing human ovarian cancer datasets and human EOC tissue arrays. We found that high expression of ST3GalI was associated with advanced stage EOC. Transwell migration and cell invasion assays showed that high ST3GalI expression enhanced migration of EOC cells. We also observed that there was a linear relation between ST3GalI expression and epidermal growth factor receptor (EGFR) signaling in EOC patients, and that high ST3GalI expression blocked the effect of EGFR inhibitors. Co-Immunoprecipitation experiments demonstrated that ST3GalI and EGFR were present in the same protein complex. Inhibition of ST3GalI using a competitive inhibitor, Soyasaponin I (SsaI), inhibited tumor cell migration and dissemination in the in vivo mouse model with transplanted MOSEC cells. Further, SsaI synergistically enhanced the anti-tumor effects of EGFR inhibitor on EOC cells. Our study demonstrates that ST3GalI regulates ovarian cancer cell migration and peritoneal dissemination via EGFR signaling. This suggests α2,3-linked sialylation inhibitors in combination with EGFR inhibitors could be effective agents for the treatment of EOC.

Fatty Acid Oxidation-Driven Src Links Mitochondrial Energy Reprogramming and Oncogenic Properties in Triple-Negative Breast Cancer.

Transmitochondrial cybrids and multiple OMICs approaches were used to understand mitochondrial reprogramming and mitochondria-regulated cancer pathways in triple-negative breast cancer (TNBC). Analysis of cybrids and established breast cancer (BC) cell lines showed that metastatic TNBC maintains high levels of ATP through fatty acid ß oxidation (FAO) and activates Src oncoprotein through autophosphorylation at Y419. Manipulation of FAO including the knocking down of carnitine palmitoyltransferase-1A (CPT1) and 2 (CPT2), the rate-limiting proteins of FAO, and analysis of patient-derived xenograft models confirmed the role of mitochondrial FAO in Src activation and metastasis. Analysis of TCGA and other independent BC clinical data further reaffirmed the role of mitochondrial FAO and CPT genes in Src regulation and their significance in BC metastasis.

Periostin in tumor microenvironment is associated with poor prognosis and platinum resistance in epithelial ovarian carcinoma.

The interplay between tumor microenvironment and cancer that causes chemoresistance remains unclear. By analyzing public available microarray datasets, we identified that periostin (POSTN) was overexpressed in cancer stroma in epithelial ovarian cancer (EOC) patients. Immunohistochemistry analysis showed overexpression of stromal POSTN is a powerful independent poor prognostic predictor for EOC patients. Furthermore, patients with high levels of stromal POSTN tend to have higher percentage of cisplatin resistance compared to those with low levels of stromal POSTN. Moreover, we found POSTN treatment can induce cisplatin resistant and activate AKT pathway in A2780 cells in vitro. Inhibition of AKT activity by AKT inhibitor MK-2206 abolished POSTN-induced AKT activation and cisplatin resistance in vitro. Taken together, we found high POSTN expression in cancer microenvironment is correlated with poor prognosis in EOC patients and associated with platinum resistance. The effect of POSTN in cancer stroma cells may activate AKT pathway in tumor and AKT inhibitor can be beneficial to augment the efficacy of existing cancer therapeutics.

Posttraumatic growth and psychological distress in Chinese early-stage breast cancer survivors: a longitudinal study.

OBJECTIVE: To describe the dynamic changes in posttraumatic growth (PTG) and psychological distress in hospitalized early-stage breast cancer (BC) survivors over a 6-month period. METHODS: A longitudinal study design was adopted. The PTG inventory (PTGI) and distress management screening measure were used 3 months after diagnosis, then again at 6 and 9 months after diagnosis. For baseline data, 155 BC patients who were receiving chemotherapy were selected from four first-class tertiary hospitals in Beijing from April 2010 to March 2011 using a purposive sampling method. Of these, 120 BC patients completed the follow-up investigation. A repeated measures analysis of variance, followed by least significant difference post-hoc analysis, was used to compare PTG and psychological distress. RESULTS: The total score of the PTGI was 62.72 ± 14.66 in BC survivors at 3 months after diagnosis.There was a weak negative relationship between PTG and psychological distress (r = ­0.282, p<0.001).PTG increased and psychological distress decreased from 3 to 9 months after diagnosis. The PTGI scores were 63.24 ± 14.21, 68.26 ± 15.29, and 70.29 ± 16.07 at 3, 6, and 9 months after diagnosis, respectively, with distress thermometer scores of 3.62 ± 1.98, 2.59 ± 2.00, and 2.51 ± 1.00, respectively. CONCLUSIONS: At 3 months after diagnosis, BC survivors develop PTG at a low level while they are receiving chemotherapy. PTG showed a weak negative association with psychological distress. The level of PTG shows an increasing tendency, whereas the degree of psychological distress exhibits a downward trend in the 9 months after diagnosis.
