A Systematic Review Evaluating the Diagnostic Efficacy of Narrow-Band Imaging for Laryngeal Cancer Detection.

Background: Narrow-band imaging is an advanced endoscopic technology used to detect changes on the laryngeal tissue surface, employing a comparative approach alongside white-light endoscopy to facilitate histopathological examination. Objective: This study aimed to assess the utility and advantages of NBI (narrow-band imaging) in identifying malignant laryngeal lesions through a comparative analysis with histopathological examination. Methods: We conducted a systematic literature review, utilizing databases such as PubMed, the CNKI database, and Embase for our research. Results: We analyzed the articles by reviewing their titles and abstracts, selecting those we considered relevant based on determined criteria; in the final phase, we examined the relevant studies according to the specific eligibility criteria. Conclusions: Narrow-band imaging is an advanced endoscopic technology that demonstrates its efficacy as a tool for diagnosing malignant laryngeal lesions and comparing them to premalignant lesions. The European Society of Laryngology has implemented a standardized classification system for laryngeal lesions to enhance data correlation and organization.

Association between anesthesia assistance and precancerous lesions and early cancer detection during diagnostic esophagogastroduodenoscopy: a propensity score-matched retrospective study.

Esophagogastroduodenoscopy (EGD) is a fundamental procedure for early detection of upper gastrointestinal (UGI) cancer. However, limited research has been conducted on the impact of sedation during EGD on the identification of precancerous lesions and early cancer (EC). This retrospective study aims to evaluate whether sedation during EGD can improve the detection rates of precancerous lesions and EC. In this propensity score-matched retrospective study, we examined medical records from outpatients who underwent diagnostic EGD at a large tertiary center between January 2023 and December 2023. Data on endoscopic findings and histology biopsies were obtained from an endoscopy quality-control system. The primary objective was to compare the rates of detecting precancerous lesions and EC in patients who received sedation during EGD vs. those who did not receive sedation. Additionally, we aimed to identify factors influencing these detection rates using binary logistic regression analysis. Following propensity score matching, a total of 17,862 patients who underwent diagnostic EGD with or without propofol sedation were identified. The group that received sedation exhibited a higher detection rate of precancerous lesions and EC in comparison to the non-sedated group (1.04 vs. 0.75%; p = 0.039). Additionally, within the sedated group, there was an increased likelihood of identifying precancerous lesions and EC specifically at the gastric antrum (0.60 vs. 0.32%, p = 0.006). Binary logistic regression analysis demonstrated that independent risk factors influencing the detection rates included age, gender, observation time, and number of biopsies conducted during the procedure. Anesthesia assistance during EGD screening proved advantageous in detecting EC as well as precancerous lesions. It is crucial for endoscopists to consider these factors when performing EGD screening procedures.

Characteristics and clinical significance of tertiary lymphoid structures in OSCC.

This study aimed to investigate the characteristics of tertiary lymphoid structures (TLSs) in oral squamous cell carcinoma (OSCC) and their association with clinical and pathological features. 12 TLS-related chemokines in TCGA database were analyzed to investigate the TLSs in OSCC. The density, maturity, and location of TLSs in a large cohort of 189 OSCC patients (114 of which had clinical and prognostic information) were assessed. And the significance between TLSs and clinicopathologic characteristics was analyzed. Bioinformatics and analysis showed that TLSs were associated with better clinical outcomes in OSCC. Histological staining and analysis showed that the overall survival rate of the high-density group (71/112, 63.4%) was significantly higher (p < 0.0001) than that of the low-density group (41/112, 36.6%), and the high-density group had fewer lymph node metastases (50.0%/68.3%, p = 0.021). And TLSs were divided into 4 types according to the maturity and location. Different types of TLSs are associated with prognosis (OS, p < 0.0001), clinical features (T stage, p = 0.028; degree of differentiation, p = 0.043), and precancerous lesion types (OSF, p = 0.049) of OSCC patients. TLSs were closely associated with better OSCC prognosis, and a more systematic classification may better guide the formulation of further treatment options.

PRF Lysates Modulate Chemokine Expression in Oral Squamous Carcinoma and Healthy Epithelial Cells.

Platelet-rich fibrin (PRF), originally used to support soft tissue healing, is also considered a therapeutic option for treating oral lichen planus and leukoplakia. The progression from the two premalignant lesions to the aggressive malignant oral squamous cell carcinoma involves an inflammatory process linked to chemokine expression. Thus, there is a rationale for studying how PRF modulates the expression of chemokines in oral squamous carcinoma cells. To this aim, we expose the oral squamous carcinoma cell line HSC2 to IL1β and TNFα either alone or in the presence of lysates obtained from solid PRF membranes. We report here that in HSC2 cells, PRF lysates significantly reduce the forced transcription of chemokines, e.g., CXCL1, CXCL2, CXCL8, CXCL10, and CCL5. Moreover, PRF lysates attenuate the nuclear translocation of p65 in HSC2 oral epithelial cells when exposed to IL1β and TNFα. PRF lysates further reduce chemokine expression provoked by poly:IC HMW. Even though less pronounced, PRF lysates reduce IL1β- and TNFα-induced chemokine expression in TR146 cells. In primary oral epithelial cells, however, PRF lysates increase the basal expression of CXCL1, CXCL2 and CXCL8. Thus, PRF can exert a biphasic effect on chemokine expression in oral squamous cell carcinoma cell lines and primary oral epithelial cells. These findings suggest that PRF may reduce inflammation in a malignant environment while provoking an immunological response in healthy oral epithelium.

DNA Methylation Biomarkers in Stool Samples: Enhancing Colorectal Cancer Screening Strategies.

Colorectal cancer (CRC) is a significant global health challenge, ranking among the leading causes of cancer-related mortality worldwide. Despite efforts in prevention and early detection, CRC incidence and mortality rates are expected to rise substantially. Traditional screening methods like gFOBT, FIT, flexible sigmoidoscopy, colonoscopy, CTC, and colon capsule have limitations, including false positives/negatives, limited scope, or invasiveness. Recent developments in CRC screening involve DNA methylation biomarkers, showing promise in detecting early-stage CRC and precancerous lesions. Stool-based DNA testing is emerging as a noninvasive and convenient method for detecting CRC-associated DNA methylation alterations, offering potential for earlier detection compared to traditional methods. Several commercial stool-based DNA methylation tests targeting different genes associated with CRC have demonstrated varying sensitivity and specificity, some surpassing traditional screening methods. Challenges remain in optimizing their performance and accessibility. This review discusses how DNA methylation biomarkers could enhance CRC screening, and stool-based DNA methylation tests could revolutionize CRC screening practices, comparing them to the gold standard.

Prevalence of sexually transmitted infections and human papillomavirus in cervical samples from incarcerated women in São Paulo, Brazil: a retrospective single-center study.

Sexually transmitted infections (STIs) cause considerable morbidity worldwide and, depending on the specific pathogen, may lead to serious complications in the female reproductive tract. Incarcerated women are particularly vulnerable to health problems with a disproportionate high rate of STIs, including infections with human papillomavirus (HPV). Here, cervical swab samples collected from 299 women (18 to 64 years) living in one of the women's prisons of São Paulo, Brazil were submitted for liquid-based cytology to determine the prevalence of precancerous lesions. Furthermore, direct detection of 30 genital HPV genotypes (18 high-risk and 12 low-risk types) and 11 additional STIs (Chlamydia trachomatis, Neisseria gonorrhoeae, Herpes simplex virus 1 and 2, Haemophilus ducreyi, Mycoplasma genitalium and hominis, Treponema pallidum, Trichomonas vaginalis, Ureaplasma parvum and urealyticum) were performed by molecular typing using two PCR-based DNA microarray systems, i.e., EUROArray HPV and EUROArray STI (EUROIMMUN), respectively. The overall prevalence of cytological abnormalities was 5.8%, including five women with low-grade and five women with high-grade squamous intraepithelial lesions. The overall prevalence of HPV was 62.2, and 87.1% of the HPV-positive women were infected with oncogenic high-risk (HR) HPV types. HPV types 16 (24.1%), 33 and 52 (both 10.4%) were the most frequently detected. The prevalence of the other STIs was 72.8%. Up to four different pathogens were found in the infected women, the most frequent being Ureaplasma parvum (45.3%), Mycoplasma hominis (36.2%) and Trichomonas vaginalis (24.8%). The high number of HR-HPV infections and other STIs described here highlights the fact that the Brazilian female prison population requires more attention in the country's health policies. The implementation of screening programs and treatment measures might contribute to a decrease in the incidence of STIs and cervical cancer in this vulnerable population. However, for such measures to be effective, further studies are needed to investigate the best practice to get more women to engage in in-prison prevention programs, e.g., through offering further sexual health education and self-sampling.

Senescent cancer-associated fibroblasts in pancreatic adenocarcinoma restrict CD8+ T cell activation and limit responsiveness to immunotherapy in mice

Senescent cells within tumors and their stroma exert complex pro- and anti-tumorigenic functions. However, the identities and traits of these cells, and the potential for improving cancer therapy through their targeting, remain poorly characterized. Here, we identify a senescent subset within previously-defined cancer-associated fibroblasts (CAFs) in pancreatic ductal adenocarcinomas (PDAC) and in premalignant lesions in mice and humans. Senescent CAFs isolated from mouse and humans expressed elevated levels of immune-regulatory genes. Depletion of senescent CAFs, either genetically or using the Bcl-2 inhibitor ABT-199 (venetoclax), increased the proportion of activated CD8+ T cells in mouse pancreatic carcinomas, whereas induction of CAF senescence had the opposite effect. Combining ABT-199 with an immune checkpoint therapy regimen significantly reduced mouse tumor burden. These results indicate that senescent CAFs in PDAC stroma limit the numbers of activated cytotoxic CD8+ T cells, and suggest that their targeted elimination through senolytic treatment may enhance immunotherapy.

The mechanism of low molecular weight fucoidan-incorporated nanofiber scaffolds inhibiting oral leukoplakia via SR-A/Wnt signal axis.

Oral leukoplakia (OLK) is the most common oral precancerous lesion, and 3%-17% of OLK patients progress to oral squamous cell carcinoma. OLK is susceptible to recurrence and has no effective treatment. However, conventional drugs have significant side effects and limitations. Therefore, it is important to identify drugs that target OLK. In this study, scavenger receptor A (SR-A) was found to be abnormally highly expressed in the oral mucosal epithelial cells of OLK patients, whereas molecular biology studies revealed that low molecular weight fucoidan (LMWF) promoted apoptosis of dysplastic oral keratinocytes (DOK) and inhibited the growth and migration of DOK, and the inhibitory effect of LMWF on OLK was achieved by regulating the SR-A/Wnt signaling axis and related genes. Based on the above results and the special situation of the oral environment, we constructed LMWF/poly(caprolactone-co-lactide) nanofiber membranes with different structures for the in-situ treatment of OLK using electrospinning technology. The results showed that the nanofiber membranes with a shell-core structure had the best physicochemical properties, biocompatibility, and therapeutic effect, which optimized the LMWF drug delivery and ensured the effective concentration of the drug at the target point, thus achieving precise treatment of local lesions in the oral cavity. This has potential application value in inhibiting the development of OLK.

A Boundary-Enhanced Decouple Fusion Segmentation Network for Diagnosis of Adenomatous Polyps.

Adenomatous polyps, a common premalignant lesion, are often classified into villous adenoma (VA) and tubular adenoma (TA). VA has a higher risk of malignancy, whereas TA typically grows slowly and has a lower likelihood of cancerous transformation. Accurate classification is essential for tailored treatment. In this study, we develop a deep learning-based approach for the localization and classification of adenomatous polyps using endoscopic images. Specifically, a pre-trained EGE-UNet is first adopted to extract regions of interest from original images. Multi-level feature maps are then extracted by the feature extraction pipeline (FEP). The deep-level features are fed into the Pyramid Pooling Module (PPM) to capture global contextual information, and the squeeze body edge (SBE) module is then used to decouple the body and edge parts of features, enabling separate analysis of their distinct characteristics. The Group Aggregation Bridge (GAB) and Boundary Enhancement Module (BEM) are then applied to enhance the body features and edge features, respectively, emphasizing their structural and morphological characteristics. By combining the features of the body and edge parts, the final output can be obtained. Experiments show the proposed method achieved promising results on two private datasets. For adenoma vs. non-adenoma classification, It achieved a mIoU of 91.41%, mPA of 96.33%, mHD of 11.63, and mASD of 2.33. For adenoma subclassification (non-adenomas vs. villous adenomas vs. tubular adenomas), it achieved a mIoU of 91.21%, mPA of 94.83%, mHD of 13.75, and mASD of 2.56. These results demonstrate the potential of our approach for precise adenomatous polyp classification.

A gel plaster in the form of nipple cover: A comfortable and safe transdermal delivery method for mammary hyperplasia

Hyperplasia of mammary glands (HMG) is considered a precancerous condition with a risk of malignant transformation, highlighting the necessity of proactive treatment in the early stages. Transdermal drug delivery offers significant advantages such as painlessness, absence of first-pass effect, and good patient compliance. However, the unique structure of the breast requires transdermal formulations for treating mammary hyperplasia to exhibit higher levels of safety and comfort. We have formulated an ancient topical formula called ’Muxiang Bing,’ comprising traditional Chinese medicines Aucklandiae Radix (AR) and Rehmanniae Radix (RR), for the treatment of HMG. This formula has been transformed into a gel paster in the form of nipple cover for trans-nipple-areola delivery. In our investigations, we observed that the optimal formulation of the Muxiang gel plaster demonstrated enhanced permeation facilitated by AR’s effect on RR. Furthermore, pre-treatment with the Muxiang gel plaster improved mammary tissue morphology, hormone levels, oxidative stress, aberrant cell proliferation, and damage in rat models, thus preventing and ameliorating mammary hyperplasia. The Muxiang gel plaster exhibited low skin irritability in rats, and long-term use did not cause harm to their internal organs or blood cells, indicating its safety and efficacy.

Penile intraepithelial neoplasia incidence, clinical classification, microenvironment and implications for imiquimod treatment.

To provide an outline of the existing data on penile intraepithelial neoplasia (PeIN), as well as a narrative review on imiquimod (IQ; a toll-like receptor 7 agonist) treatment and immune microenvironment markers that may predict response to treatment. A narrative review of the literature from 2000 to the present was conducted on PubMed, and we describe the most relevant data and cross references. The incidence of PeIN is increasing. Local therapy with IQ may offer an easy applicable treatment with complete response rates of up to 63% but can be associated with considerable side-effects. There is no conclusive data on the optimal treatment schedule for PeIN, but evaluation of treatment results for other human papillomavirus-related pre-malignancies suggest three times a week for a duration up to 16 weeks. There are no published studies concerning the PeIN immune microenvironment. However, findings from the few studies on penile cancer and pre-cancerous vulvar and cervical lesions imply that specific immune cell subpopulations can serve as future predictors for successful immunomodulation treatments such as IQ. Overall, limited data are available on IQ treatment for PeIN and no published data exists on the PeIN immune microenvironment. Further translational studies are warranted to gain more understanding on the pathophysiology of PeIN and potential predictors of progression and of response to topical treatments.

Surgical Care Through a Community Free Clinic-Ambulatory Surgical Center Partnership.

Disparities secondary to underinsurance present throughout the surgical care continuum. Community free clinics are uniquely capable to provide health care services to the medically underserved, but surgery often falls outside their scope of care. Retrospective chart review was conducted on consecutive community free clinic patients receiving free surgical services via referral to a partnering ambulatory surgery center between March 2016 and September 2021. Those with documented contact information were recruited 1-3 years post-procedure for long-term quality-of-life (LTQOL) outcomes assessment via modified Veterans RAND 12-item health survey. Of 142 included patients, 95.7% identified as Hispanic/Latino and 75.6% were uninsured. Twelve patients had cancerous or precancerous lesions detected and/or removed through diagnostic or definitive procedures. 3.5% experienced postoperative complication including bacterial (n = 2) or fungal (n = 1) surgical site infection and wound dehiscence (n = 2). With a 48.9% response rate, no significant differences in sociodemographic or clinical characteristics were found between surveyed vs non-surveyed patients. Of surveyed patients, 59.7% and 52.2% reported pre-/post-operative improvement in physical health and emotional health, respectively. Free diagnostic screening procedures provided timely diagnoses while free definitive surgeries safely and positively impacted long-term patient-reported physical health. Longitudinal, multidisciplinary follow-up and social support may be warranted to concurrently improve emotional and mental health in similarly underinsured populations.

Resolutive Treatment of Actinic Keratosis through Peptides Extracted from Zebrafish Conveyed Across Laser-assisted Transcutaneous Delivery (Cryopass Therapy).

Actinic keratoses (AKs) are humans' most common keratinocyte-derived precancerous lesions. They can be observed predominantly in fair-skinned individuals on sun-exposed surfaces. Another name for AKs is solar keratosis. The primary risk factor for AKs is cumulative UV exposure from sunlight and/or tanning salons. AKs may present on a patient as a few detectable lesions. Clinically, they present as scaly erythema lesions with various pigmentations. Surgery treatment is the only approach that can definitively resolve the illness. The research aims to demonstrate the effectiveness of treating relapsing AKs through the use of factors present during organogenesis extracted from zebrafish caviar conveyed through a cryopass therapy device (cryolaser phoresis). These factors are peptides present during specific phases of organogenesis and have shown the capacity to reverse cancer and neurodegeneration processes through gene, transcriptional, translational, and post-translational regulation. We found that 90% of patients responded. The percentage of responding patients was 100% among females and 80% among men. Our results confirm previous findings about the effectiveness of stem cell differentiation stage factors (SCDFs) in cancer and open new ways to integrate treatment.

Cervical cancer in Malaysia.

Cervical cancer is preventable due to effective screening to detect pre-malignant lesion, and vaccination against its causative organism namely human papillomavirus (HPV). This review article described current situation of cervical cancer in Malaysia. There is decreasing cervical cancer incidence in the country, with age-standardized rate of 10.3, versus 14.1 and 7.5 per 100 000 for worldwide and high-income countries, respectively. School-based HPV vaccination is part of national immunization since 2010, with yearly coverage rate of 83%-91%. The figure declined during coronavirus disease-19 pandemic due to scarce vaccine supply and movement-control order, resulting in about 500 000 students missing their course, with catch-up program currently onboard. Opportunistic cervical screening program started in 1960s with cervical smear cytology, which is succeeded by HPV DNA screening since 2020. Cervical cytology remains indispensable screening method in healthcare facility without access to HPV test kit, and used to triage high-risk HPV positive with abnormal cytology that require urgent colposcopy. Computed tomography is the main imaging modality to assess local and distal extent of cervical cancer. Primary surgical treatment for early-stage cancer is performed by trained gynecologic oncologist, with long waiting list for radiation therapy in locally advanced disease due to limited available public facility. There is restricted access to targeted therapy due to high treatment cost. In conclusion, Malaysia is heading toward cervical cancer elimination through rigorous investment in primary and secondary prevention, and increase in public engagement with the support of government policy enforcement.

Transcriptome and microbiome-immune changes across preinvasive and invasive anal cancer lesions.

Anal squamous cell carcinoma (ASCC) is a rare gastrointestinal malignancy linked to high-risk Human papillomavirus (HPV) infection, which develops from precursor lesions like Low-Grade Squamous Intraepithelial Lesions (LGSIL) and High-Grade Squamous Intraepithelial Lesions (HGSIL). ASCC incidence varies across populations, posing increased risk for People Living with HIV (PLWH). Our investigation focused on transcriptomic and metatranscriptomic changes from Squamous Intraepithelial Lesions (SILs) to ASCC. Metatranscriptomic analysis highlighted specific bacterial species (e.g., Fusobacterium nucleatum, Bacteroides fragilis) more prevalent in ASCC than precancerous lesions. These species correlated with gene encoding enzymes (Acca, glyQ, eno, pgk, por) and oncoproteins (FadA, dnaK), presenting potential diagnostic or treatment markers. Unsupervised transcriptome analysis identified distinct sample clusters reflecting histological diagnosis, immune infiltrate, HIV/HPV status, and pathway activities, recapitulating anal cancer progression's natural history. Our study unveiled molecular mechanisms in anal cancer progression, aiding in stratifying HGSIL cases based on low- or high-risk progression to malignancy.

Endoscopic Surveillance of Gastric Intestinal Metaplasia: A Retrospective Cohort Study.

Gastric intestinal metaplasia (GIM) is a precancerous condition. Limited data exist on real-world clinical practice relative to guidelines. The aim of this study was to evaluate adherence to GIM risk stratification and identify factors associated with follow-up endoscopy. We conducted manual chart review of patients with histologically confirmed GIM at an urban, tertiary medical center were identified retrospectively and details of their demographics, Helicobacter pylori, biopsy protocol, endoscopic/histologic findings, and postendoscopy follow-up were recorded. Multivariable logistic regression was used to identify factors independently associated with follow-up endoscopy. Among 253 patients, 59% were female, 37% non-Hispanic White (NHW), 26% Hispanic, 16% non-Hispanic Black (NHB). The median age at index endoscopy was 63.4 years (IQR: 55.9 to 70.0), with median follow-up of 65.1 months (IQR: 44.0 to 72.3). H. pylori was detected in 21.6% patients at index EGD. GIM extent and subtype data were frequently missing (22.9% and 32.8%, respectively). Based on available data, 26% had corpus-extended GIM and 28% had incomplete/mixed-type GIM. Compared with NHW, Hispanic patients had higher odds of follow-up EGD (OR=2.48, 95% CI: 1.23-5.01), while NHB patients had 59% lower odds of follow-up EGD (OR=0.41, 95% CI: 0.18-0.96). Corpus-extended GIM versus limited GIM (OR=2.27, 95% CI: 1.13-4.59) was associated with follow-up EGD, but GIM subtype and family history of gastric cancer were not. We observed suboptimal risk stratification among patients with GIM and notable race and ethnic disparities with respect to endoscopic surveillance. Targeted interventions are needed to improve practice patterns and mitigate observed disparities.

The Rare Condition of a Double Cervix: Results from the High-Risk Human Papillomavirus-Based Cervical Cancer Screening Program in the Lazio Region.

Precancerous and cancerous lesions of the uterine cervix are known to be associated with Human Papillomavirus (HPV) infection. The screening of high-risk (HR)-HPV infection in the female population has led to the discovery of several cases of a double cervix, a congenital malformation that is very rare. The purpose of this study was to evaluate HR-HPV infections in women with a double cervix within the National Cervical Cancer Screening program of the Lazio region (Italy). From June 2021 to March 2024, a total of 142,437 samples were analyzed by Seegene's Anyplex TM II HR-HPV method, which identifies 14 HR-HPV genotypes. For each woman identified with a double cervix, two separate samples were taken from both cervices and analyzed separately. Twenty-seven women with a double cervix were identified (0.019%): 23 women were tested as negative for both cervices, while the remaining four (namely A, B, C, and D) resulted positive. By genotyping, the following results were obtained: (A) Both samples showed genotype 31; (B) one cervix was negative while the other showed genotype 58; (C) one cervix was positive for HPV 18 and 31 while for 18, 31, and 33 in the other; and (D) one cervix showed genotype 66 while the other carried the 66 and 68 genotypes. Double cervix is a very rare condition where the presence of HR-HPV genotypes is not homogeneous. As already described, our study confirms that different genotypes can be detected in double cervix malformation, suggesting the need to perform HPV screening on brushing samples from both cervices.

The role of cervicovaginal microbiota in the occurrence of severe cervical intraepithelial dysplasia

BACKGROUND: Despite the availability of visual examination of the cervix, cervical screening in Russia has not been widespread enough, and therefore the incidence of cervical cancer remains consistently high. In recent years, the vaginal microbiota is given special attention as a risk factor for the development of precancerous diseases of the cervix. AIM: The aim of this study was to compare the cervicovaginal microbiota in patients with high-grade squamous intraepithelial lesions (HSIL) or negative for intraepithelial lesions or malignancy (NILM). MATERIALS AND METHODS: Microorganisms isolated from the cervicovaginal microbiota were identified in 40 patients using the mass spectrometry method. 20 women had severe cervical dysplasia, and the other 20 were healthy women without precancerous cervical lesions. RESULTS: Corynebacterium spp. and Streptococcus spp. were found more often in the cervicovaginal microbiome in patients with high-grade squamous intraepithelial lesions than in women negative for intraepithelial lesions or malignancy. CONCLUSIONS: The data obtained suggest that the presence of Corynebacterium spp. and Streptococcus spp. in the cervicovaginal microbiota is associated with the presence of severe cervical intraepithelial changes.

How important is early Disease Detection through Regular Systematic Examinations in People older than 65 Years: An Example of Two Cases

Early detection of cancer in people over the age of 65 is a key aspect in the fight against this vicious disease. Aging of the body carries with it a number of changes that increase the susceptibility to developing cancer, with greater exposure to risk factors throughout the lifespan. Given this vulnerability, recognizing and treating cancer at an early stage becomes essential. In addition to enabling earlier treatment, early detection provides a better prognosis of the disease and requires less invasive treatments, thus reducing treatment costs and improving patients’ quality of life. Early detection of cancer plays a key role in prevention, allowing the identification of precancerous conditions and risk factors and encouraging preventive measures to be taken. Therefore, it is very important to conduct regular systematic examinations and screenings for cancer among the elderly, it becomes imperative to ensure the detection of possible tumors at their initial stage and ensure timely start of treatment.
