Knowledge of breast cancer among medical students in Syrian Private University, Syria: a cross-sectional study

Assessment of breast cancer awareness among female pharmacy students at a university in Turkey

BACKGROUND

Female breast cancer is the most frequently diagnosed cancer, and knowledge of breast cancer risk factors, and symptoms is crucial for early diagnosis and prevention. This study aims to evaluate breast cancer awareness among female students at a pharmacy faculty in Turkey.

METHODS

A cross-sectional online survey study was conducted among female students at the Suleyman Demirel University Faculty of Pharmacy between 2 November and 17 November 2023, in Isparta, Turkey.

RESULTS

This survey was answered by 237 (74.5%) female students. The median breast cancer risk factors score was 8 (IQR, 5-11), and the median breast cancer symptoms score was 5 (IQR, 2-8). Additionally, the breast cancer risk factors score was 46.16% (mean/max = 8.31/18, SD = 4.33) and the breast cancer symptom score was 58.5% (mean/max = 4.68/8, SD = 2.8). Few of the respondents (26.2%, and 20.3%, respectively) knew breast cancer risk factors such as late menopause, and no childbirth experience. Most respondents correctly answered symptoms of breast cancer, such as a painless and palpable breast lump, indrawing of the nipple, and sudden changes in breast shape (76.8%,44.3%, and 67.1% respectively). The students' sources of information were medical websites (29.5%), social media (27%), physicians (22.8%), friends & family (14.8%), and pharmacists (5.9%).

CONCLUSIONS

This study showed that students' knowledge of breast cancer risk factors was poor, but their knowledge of breast cancer symptoms was acceptable. Breast cancer awareness courses should be included in faculties. Additionally, more attention should be given to different educational interventions such as social media, television, and brochure distribution.

Construction and validation of a hypoxia-related gene signature to predict the prognosis of breast cancer

BACKGROUND

Among the most common forms of cancer worldwide, breast cancer posed a serious threat to women. Recent research revealed a lack of oxygen, known as hypoxia, was crucial in forming breast cancer. This research aimed to create a robust signature with hypoxia-related genes to predict the prognosis of breast cancer patients. The function of hypoxia genes was further studied through cell line experiments.

MATERIALS AND METHODS

In the bioinformatic part, transcriptome and clinical information of breast cancer were obtained from The Cancer Genome Atlas(TCGA). Hypoxia-related genes were downloaded from the Genecards Platform. Differentially expressed hypoxia-related genes (DEHRGs) were identified. The TCGA filtered data was evenly split, ensuring a 1:1 distribution between the training and testing sets. Prognostic-related DEHRGs were identified through Cox regression. The signature was established through the training set. Then, it was validated using the test set and external validation set GSE131769 from Gene Expression Omnibus (GEO). The nomogram was created by incorporating the signature and clinicopathological characteristics. The predictive value of the nomogram was evaluated by C-index and receiver operating characteristiccurve. Immune microenvironment and mutation burden were also examined. In the experiment part, the function of the two most significant hypoxia-related genes were further explored by cell-line experiments.

RESULTS

In the bioinformatic part, 141 up-regulated and 157 down-regulated DEHRGs were screened out. A prognostic signature was constructed containing nine hypoxia genes (ALOX15B, CA9, CD24, CHEK1, FOXM1, HOTAIR, KCNJ11, NEDD9, PSME2) in the training set. Low-risk patients exhibited a much more favorable prognosis than higher-risk ones (P < 0.001). The signature was double-validated in the test set and GSE131769 (P = 0.006 and P = 0.001). The nomogram showed excellent predictive value with 1-year OS AUC: 0.788, 3-year OS AUC: 0.783, and 5-year OS AUC: 0.817. Patients in the high-risk group had a higher tumor mutation burden when compared to the low-risk group. In the experiment part, the down-regulation of PSME2 inhibited cell growth ability and clone formation capability of breast cancer cells, while the down-regulation of KCNJ11 did not have any functions.

CONCLUSION

Based on 9 DEHRGs, a reliable signature was established through the bioinformatic method. It could accurately predict the prognosis of breast cancer patients. Cell line experiment indicated that PSME2 played a protective role. Summarily, we provided a new insight to predict the prognosis of breast cancer by hypoxia-related genes.

A Single Centric Quantitative Assessment of Male Breast Cancer Knowledge, Perception, and Awareness: Breaking the Stigma in Indian Population

Most people throughout the world are still uninformed of the problem of breast cancer in men. Despite increasing awareness programs targeting women, most people are unaware that breast cancer can also affect men. Our purpose is to assess the knowledge, perception, and awareness of male breast cancer among the adult male population. A descriptive cross-sectional survey included 128 male employees who agreed to participate in our study. We distributed pre-validated questionnaires to participants and gathered data following the one-on-one interview. The mean age of the participants was 37.71 years with a standard deviation of 7.65. About 55.5% of the participants were unaware that changes in the nipple position could be a sign of breast cancer. Majority of the participants, i.e., 60.9% believe positive family history will not increase the risk of breast cancer and 93% of participants have no idea about self-breast examination to detect lumps. On the other hand, 33.6% of participants stated that diagnosis and treatment of male breast cancer is embarrassing. Majority of the participants have no idea about the screening methods, 59.4% of participants have not heard about mammography, which is considered a modality of choice for early detection of breast cancer. The male university staff were lacking in knowledge and awareness about male breast cancer. In Indian community, because of shyness, they feel very embarrassed when it comes to openly discussing breast cancer. Because of this, it needs to receive more attention and to educate the male population about male breast cancer.

Anti-proliferative activity of RIHMS-Qi-23 against MCF-7 breast cancer cell line is through inhibition of cell proliferation and senescence but not inhibition of targeted kinases

BACKGROUND

Breast cancer is the most common malignancy globally, and is considered a major cause of cancer-related death. Tremendous effort is exerted to identify an optimal anticancer drug with limited side effects. The quinoline derivative RIMHS-Qi-23 had a wide-spectrum antiproliferative activity against various types of cancer cells.

METHODS

In the current study, the effect of RIMHS-Qi-23 was tested on MCF-7 breast cancer cell line to evaluate its anticancer efficacy in comparison to the reference compound doxorubicin.

RESULTS

Our data suggest an anti-proliferative effect of RIMHS-Qi-23 on the MCF-7 cell line with superior potency and selectivity compared to doxorubicin. Our mechanistic study suggested that the anti-proliferative effect of RIMHS-Qi-23 against MCF-7 cell line is not through targeted kinase inhibition but through other molecular machinery targeting cell proliferation and senescence such as cyclophlin A, p62, and LC3.

CONCLUSION

RIMHS-Qi-23 is exerting an anti-proliferative effect that is more potent and selective than doxorubicin.

Evaluation of the Knowledge of the Most Common Cancers Among Health Students at Jazan University, Saudi Arabia: A Cross-Sectional Study

BACKGROUND

Cancer is a major public health problem worldwide, and medical students are expected to have adequate knowledge and awareness of the most common types of cancer. This study aimed to assess the cancer knowledge of medical students at Jazan University, Saudi Arabia, focusing on breast cancer (BC), prostate cancer (PC), cervical cancer (CC), and colorectal cancer (CRC).

METHODS

This study employed a self-administered survey to evaluate both general and specialized knowledge of cancer types. A total of 321 medical students from different academic years participated in the study. The questionnaire used a scoring system where each correct answer was given one point, and each incorrect answer or "I don't know" response was given zero points.

RESULTS

The overall knowledge scores were 18.75 ± 4.43 out of 28 (67%). The students had a good level of general knowledge about cancer (5.26 ± 1.44 out of 7, 75%) and breast cancer (5.47 ± 1.44 out of 7, 78%) and a moderate knowledge level of prostate cancer (2.83 ± 1.07 out of 4, 71%), cervical cancer (2.74 ± 1.53 out of 5, 55%), and colorectal cancer (2.55 ± 1.61 out of 5, 50%). There were significant differences in cancer knowledge by gender, academic year, and having a relative or friend with cancer. All types of cancer knowledge were positively and significantly correlated with each other.

CONCLUSION

This study revealed the strengths and weaknesses of cancer knowledge among medical students at Jazan University, Saudi Arabia. The overall score for knowledge indicated a moderate level. The students had some knowledge about cancer prevention, detection, and treatment, but some gaps and misconceptions need to be addressed. More education and awareness programs are necessary to improve cancer literacy among students and promote healthy behaviors that can reduce cancer risk.

Knowledge regarding breast cancer among Congolese women in Kinshasa, Democratic Republic of the Congo

INTRODUCTION

Breast cancer is the most frequent type of cancer in women and is characterized by late clinical signs in developing countries, including the Democratic Republic of the Congo. One of the main reasons of death from breast cancer is lack of awareness and screening, which has led to late diagnosis (at an advanced stage). This study aims to measure women's knowledge regarding breast cancer in Kinshasa, in the Democratic Republic of the Congo.

MATERIALS AND METHODS

A cross-sectional study of 489 women aged 20-65 years was conducted. Data was collected using a predesigned, tested, self-administered questionnaire. The questionnaire included specific sections to test the participants' knowledge related to breast cancer and its screening, and practices related to breast self-examination (BSE). Bivariate and multivariate analyzes were used.

RESULTS

Our results indicated that 22.09% of the participants had good breast cancer knowledge and 77.91% had poor breast cancer knowledge. Overall, 322 (65.85%) participants recognized that BSE is a valuable method for early screening of BSE. In total, 136 (27.81%) respondents had learned to do the BSE and 216 (44.17%) had reported doing it. Two hundred and ninety-two (59.71%) respondents mentioned that any woman was at risk for breast cancer and 357 (71.78%) mentioned that it was possible to prevent breast cancer. Determinants of an adequate level of knowledge were higher/university educational level (adjusted odds ratio = 2.70; 95% confidence interval: 1.27-5.73; p = .010) and having previously been screened for breast cancer (adjusted odds ratio = 2.31; 95% confidence interval: 1.40-3.83; p = .001).

CONCLUSION

The majority (77.91%) of women have demonstrated poor knowledge of signs/symptoms, risk factors, and screening methods of breast cancer. Additional efforts should be made through women's healthcare workers to raise knowledge of breast cancer screening.

Quanto você Sabe sobre Câncer de Mama? Avaliação do Nível de Conhecimento da População Brasileira

Introdução: Apesar dos esforços de conscientização da população, permanecem altas a incidência e a mortalidade decorrente de câncer de mama em mulheres brasileiras. Objetivo: Avaliar o nível de conhecimento da população brasileira sobre os fatores de risco que levam ao desenvolvimento dessa doença. Método: Foi utilizado um questionário estruturado on-line, enviado de setembro a dezembro de 2021, por meio das redes sociais e e-mail. Os participantes foram divididos em subgrupos (escolaridade, área de formação profissional, gênero, contato com indivíduos afetados pela doença e faixas de idade), e o teste de qui-quadrado foi realizado para verificar diferenças significativas entre eles. Resultados: Analisando as 200 respostas válidas da amostra como um todo, a taxa de acertos foi alta, ficando acima dos 70%. Ao contrapor os subgrupos, foram identificados resultados significativos para as análises relativas a escolaridade (p=0,016), área de formação (p=0,004), gênero (p=0,045) e proximidade com a doença (p=0,004), em que foi observado que as menores taxas de acertos foram de pessoas com o nível de escolaridade mais baixa, que não fazem parte da área de saúde, do sexo masculino e que não tiveram contato com pessoas próximas portadoras da doença. Conclusão: Foi possível avaliar o conhecimento dos participantes sobre o tema, entretanto, as ações atuais tomadas por grupos de extensão e divulgação científica e instituições de combate ao câncer de mama são válidas para alguns subgrupos, mas precisam atingir com mais qualidade pessoas de menor escolaridade, pessoas que não possuem formação na área da saúde e pessoas do sexo masculino.
