ABSTRACT

Introduction: Cervical cancer (CC) is the fourth most prevalent female cancer globally. Understanding its epidemiology is crucial for devising practical strategies suited to geographic and social contexts to attain the global eradication of CC. Hence, this study examined the latest evidence of risk factors contributing to CC development. Methods: An independent literature search was conducted on PubMed using MESH terms. The primary sources were meta-analyses published from 2010 to 2023, which detail updated evidence on risk factors associated with CC. Additionally, the quality of the evidence was evaluated using the GRADE system and recommendations were made accordingly. Results: The main risk factors related to the cause of CC include co-infections with other sexually transmitted infections, genetic markers, cervicovaginal microbiota, nutritional factors, comorbidities that affect the immune response, smoking, and the use of hormonal contraceptives with a quality evidence based on the GRADE scale moderate. Conclusions: Since the necessary cause for CC is persistent cervicovaginal HPV, all the risk factors implicated in the causality of CC act as non-independent cofactors that increase the risk of CC. Thus, changes in public policies aimed at addressing these risk factors are highly recommended and can substantially decrease the risk of CC.

ABSTRACT

BACKGROUND: In 2020, the highest incidence and mortality from cervical cancer (CC) were detected in low and middle-income countries. CC remains a health problem for women living in them. In Mexico, CC ranks second in cancer incidence and mortality in women. The main characteristics of this population are low income, low educational level, and inadequate medical coverage. The present study characterized the Mexican population by CC, and the sociodemographic variables that impacted overall survival (OS) were identified. METHODS: A retrospective study that included a cohort of patients with a confirmed diagnosis of CC at the Instituto Nacional de Cancerologia between 2003 and 2016. Information was collected on sociodemographic variables related to the disease and OS. RESULTS: Four thousand six hundred thirty-one patients were included. The median age was 51 years, 78.5% were unemployed, 44.4% lived in a rural/suburban area, 50.8% had a partner when collecting this information, and 74.3% were classified as having low socioeconomic status. Age, living in a rural/suburban area, more advanced stages of the disease, and not receiving cancer treatment were associated with lower OS. CONCLUSION: CC continues to affect mainly women with minimal resources, low educational levels, and living in marginalized areas. These characteristics influence the OS. Prevention and timely detection programs, education, and training focused on this population and with broader coverage are required to identify patients with CC at earlier stages.

ABSTRACT

BACKGROUND: Cervical cancer (CC) in Mexico is diagnosed mainly in locally advanced (LACC) and advanced (ACC) stages, where ureteral obstruction is more frequent. The standard treatment for this population is concurrent chemoradiotherapy (CCRT) with cisplatin, which is nephrotoxic and could lead to further deterioration of renal function in LACC patients with renal function decline. We aimed to evaluate the effect of CCRT with Gemcitabine on renal function in LACC patients. METHODS: This retrospective study included LACC patients treated with CCRT with Gemcitabine as a radiosensitizer from February 2003 to December 2018. Data were collected from medical archives and electronic records. We assessed renal function before and after CCRT treatment and analyzed the patient's response to treatment and survival. RESULTS: 351 LACC patients treated were included and stratified into two groups: 198 with Glomerular Filtration Rate (GFR) ≥60ml/min (group A) and 153 with GFR<60ml/min (group B). An improvement in GFR was observed after CCRT in patients in group B, from 33 ml/min to 57.5 ml/min (p<0.001). Complete response was observed in 64.1% of patients in Group A and 43.8% in Group B (p<0.0001). Factors associated with increased risk of death included having a GFR of 15-29 ml/min (HR: 2.17; 1.08-4.35), having GFR<15 ml/min (HR: 3.08; 1.63-5.79), and receiving Boost treatment (HR: 2.09; 1.18-3.69). On the other hand, receiving brachytherapy is a positive predictor for OS (HR:0.51; 0.31-0.84). CONCLUSION: CCRT with gemcitabine is an appropriate treatment option for patients diagnosed with LACC who present impaired renal function due to the disease's obstructive nature or other comorbidities.

ABSTRACT

BACKGROUND: Cancer-related cachexia (CRC) has a profound impact on health-related quality of life (HRQL), and both were reported to be associated with overall survival (OS). We hypothesize that HRQL and CRC are associated with OS. This study analyzed the impact of CRC on HRQL and its prognostic value in women with cervical cancer (CC). METHODS: A cohort study including consecutive women with CC treated from October 2020 to October 2021 in a cancer center. Cox's model defined the associations of immune, biochemical and nutritional parameters, clinical cachexia classifications and HRQL with OS. RESULTS: Two hundred forty-four consecutive women with CC were included. Cachexia classifications and several scales of the QLQ-C30 were associated with OS by bivariate but not by multivariate analysis. QLQ-CX24 scales were not associated with OS. The prognostic nutritional index (PNI) (hazard ratio (HR) 0.828; 95% confidence interval (CI) 0.766-0.896), Food aversion (HR 0.95; 95% CI 0.924-0.976), Eating difficulties (HR 1.041; 95% CI 1.013-1.071), Loss of control (HR 4.131; 95% CI 1.317-12.963), Forced self to eat (1.024; 95% CI 1.004-1.044) and Indigestion (HR 0.348; 95% CI 0.131-0.928) scales of the QLQ-CAX24 were independently associated with OS by multivariate analysis (p = 1.9×10-11). CONCLUSION: This model permitted a clear stratification of prognostic subgroups. The PNI and several QLQ-CAX24 scales were associated with OS in women with CC. CRC, defined by several cachexia classifications, was not an independent prognostic factor. These findings require confirmation because of their possible diagnostic, therapeutic and prognostic implications.The prognostic nutritional index and several QLQ-CAX24 scales were associated with overall survival in women with cervical cancer. Cancer-related cachexia, defined by several cachexia classifications, was not an independent prognostic factor, neither The International Federation of Gynecology and Obstetrics (FIGO) stage classifications.

ABSTRACT

Cancer-related cachexia (CRC) is a common phenomenon in cervical cancer (CC), severely affecting clinical response, drug toxicity and survival. The patients' point of view should be evaluated to quantify the impact of CRC, and adequate instruments to do so are required. Thus, the study aimed to validate the Mexican-Spanish version of the QLQ-CAX24 instrument in women with CC. A cohort of women with CC answered the EORTC QLQ-C30 and QLQ-CAX24 instruments. The psychometric and clinimetric properties of the instruments were assessed. Two hundred and forty-four women were included; the mean age was 50 years (IQR: 41-60) and 188 (77%) were first diagnosed in locally advanced stages. The QLQ-CAX24 internal consistency test demonstrated adequate convergent (Spearman correlation coefficient 0.08-0.709) and divergent validity (Spearman correlation coefficient 0.006-0.471). Cronbach's alpha coefficients of the three multi-item scales were >0.5 (minimum 0.539, maximum 0.84). Patients with decreased handgrip strength, low fat-free mass, or high C-reactive protein levels had worse QLQ-CAX24 scale scores. Cachexia was diagnosed with the SCRINIO, Fearon and Evans criteria, and 31.5, 32.4 and 38.5% of women had cachexia, respectively. Patients with cachexia had the worst scores in terms of quality of life. The test re-test analysis did not show differences between visits in patients without malnutrition. The Mexican-Spanish version of the QLQ-CAX24 instrument is reliable and valid. Low handgrip strength, low fat-free mass and high C-reactive protein levels were associated with poor scale scores.

ABSTRACT

Chronic diseases are responsible for approximately 71% global deaths. These are characterized by chronic low-grade inflammation and metabolic alterations. "Functional foods" have been attributed with anti-inflammatory properties, demonstrated in cell lines and murine models; however, studies in humans are inconclusive. The purpose of this systematic review is to identify clinical trials that analyzed changes in inflammatory and metabolic mediators, in response to consumption of specific functional foods. A total of 3581 trials were screened and 88 were included for this review. Foods identified to regulate inflammation included cranberries, grapes, pomegranate, strawberries, wheat, whole grain products, low fat dairy products, yogurt, green tea, cardamom, turmeric, soy foods, almonds, chia seeds, flaxseed, pistachios, algae oil, flaxseed oil and grape seed oil. Clinical trials that focus on a dietary pattern rich in functional foods are necessary to explore if the additive effect of these foods lead to more clinically relevant outcomes.

ABSTRACT

OBJECTIVE: Cervical cancer is the fourth most frequent neoplasm among women in terms of incidence and mortality. Health-related quality of life (HRQL) is an important outcome in oncology. The QLQ-CX24 instrument was developed to measure HRQL in patients with cervical cancer, and its Mexican-Spanish version had not been validated. METHODS: Between March 2018 and May 2019, Mexican women older than 18, with any-stage cervical cancer were invited to participate in the study. Patients answered the QLQ-C30 and QLQ-CX24 questionnaires. Current tests for psychometric and clinical validation were performed. RESULTS: Three hundred and thirty patients with cervical cancer were included in this study. All women invited to participate accepted and were included. The QLQ-CX24 internal consistency test demonstrated adequate convergent (Spearman correlation coefficient 0.001-0.847) and divergent validity (Spearman correlation coefficient <0.0001-0.45). Cronbach's alpha coefficients of the three multi-item scales were >0.7 (minimum 0.76, maximum 0.89). Four scales of the QLQ-CX24 distinguished patients in different clinical stages. The evaluation of responsiveness demonstrated that the peripheral neuropathy scale was sensitive to change over time during chemo-radiation therapy. Six scales of the QLQ-CX24 instrument were associated with survival. CONCLUSION: The Mexican-Spanish version of the QLQ-CX24 questionnaire is reliable and valid for the assessment of HRQL in patients with cervical cancer.

ABSTRACT

The objective was to evaluate body composition and nutritional status in women with locally advanced cervical cancer (LACC) before receiving oncologic treatment. Women with cervical cancer diagnoses in clinical stage IB2 to IIIB were studied. Body composition was measured with bioimpedance, sarcopenia determined according to the European Consensus, and nutritional status according to the Patient-Generated Subjective Global Assessment. A total of 155 women with age 50.4 ± 13.7, 29 clinical stage I, 82 II, and 44 III, were studied. Patients in advanced clinical stage III, compared with patients in stage II and stage I, lower phase angle (III: 5.2 ± 0.98 vs. II: 5.7 ± 1.9 and I: 5.8 ± 0.69, p = 0.007). Impedance vector distribution was different in patients in clinical stage III vs. those in clinical stage II (p = 0.014) and I (p = 0.039). LACC patients in advanced stages had worse body composition and nutritional status before treatment.

ABSTRACT

In the development of cervical cancer (CC), the immune response plays an essential role, from the elimination of human papillomavirus (HPV) infection to the response against the tumor. For optimal function of the immune response, various factors are required, one of the most important being an adequate nutrition. The complex interaction between nutrients and microbiota maintains the immune system in homeostasis and in case of infection, it provides the ability to fight against pathogen invasion, as occurs in HPV infection. The purpose of this article is to describe the role of diet, food, and specific nutrients in the immune response from the onset of infection to progression to precancerous lesions and CC, as well as the role of diet and nutrition during oncological treatment. The immunomodulatory role of microbiota is also discussed. A detailed analysis of the evidence leads us to recommend a nutritional pattern very similar to the Mediterranean diet or the prudent diet for an optimal immune response. Moreover, pre- and probiotics favorably modulate the microbiota and induce preventive and therapeutic effects against cancer.

ABSTRACT

BACKGROUND: The TNM classification does not completely reflect the prognosis of patients with colorectal cancer (CRC). Several clinical factors have been used to increase its prognostic value, but factors pertaining to the patient's immunonutritional status have not usually been addressed. The aim of this study is to evaluate the role of Prognostic nutritional index (PNI) and other well-known prognostic factors by multivariate analysis in a cohort of patients with CRC. METHODS: This is a retrospective cohort study of consecutive patients with CRC managed in a cancer center between January 1992 and December 2016. Cox's model was used to define the association of the PNI and other factors with Overall survival (OS). RESULTS: A total of 3301 patients were included: 47.7% were female and 52.3% were male, with a mean age of 58.7 years. By bivariate analysis, PNI was strongly associated with OS (Risk ratio [RR] 0.968, 95% Confidence interval [CI] 0.962-0.974; P < 0.001). On multivariate analysis, PNI was an independent explanatory variable (as continuous variable and as categorized variable; RR 0.732, 95% CI 0.611-0.878; RR 0.656, 95% CI 0.529-0.813 and RR 0.646, 95% CI 0.521-0.802, for quintiles 2, 3, and 4-5, respectively); a biological gradient effect was demonstrated. The final prognostic model included PNI, location of the neoplasia in the colorectum, basal hemoglobin, lymphocyte count, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, TNM stage, differentiation degree, R classification, and postoperative complications. CONCLUSIONS: PNI is a significant and independent prognostic factor in patients with CRC. Its prognostic value adds precision to the TNM staging system including specific subgroups of patients with CRC; it should be evaluated in prospective clinical studies.

ABSTRACT

PURPOSE: The cancer anorexia-cachexia syndrome (CACS) is highly prevalent in lung cancer (LC) patients (57-61%), and represents the direct cause of death in 20% of cases. Accurately quantifying CACS has been a challenging issue; consequently, this study presents the clinical validation of the Spanish version of the Functional Assessment of Anorexia-Cachexia Therapy (FAACT) scale in LC patients from Latin America. METHODS: The Spanish version of the FAACT and the Mexican-Spanish version of the EORTC-QLQ-C30 instruments were applied to a cohort of patients with LC at the National Cancer Institute of Mexico. Reliability and validity tests were performed to assess the psychometric properties of the scales, and clinical validation was assessed considering the association of scales with subjective and objective clinical data. RESULTS: Two hundred patients were included. Questionnaire compliance rates were high (100%) and the instrument was well accepted in all cases; internal consistency tests demonstrated good convergent and divergent validity of the scale structure. Cronbach's α coefficient for three out of five basic multi-item scales was > 0.7 (0.55-0.86). FAACT scales presented significant associations with clinical parameters, including biochemical and nutritional variables (i.e., energy intake, p = 0.002), as well as strongly correlated with the appetite loss subscale of the QLQ-C30 questionnaire (r = - 0.624). Physical well-being (p < 0.0009), functional well-being (p = 0.004), anorexia/cachexia scale (p = 0.029), and FAACT total scores (p = 0.0009) were strongly associated to overall survival. CONCLUSION: The Spanish version of the FAACT questionnaire is reliable and valid for the assessment of health-related quality of life and CACS in LC patients and can be used in clinical trials.

ABSTRACT

Radiotherapy is one of the main treatment options used in pelvic cancers. Ionizing radiation induces damage to surrounding tissues, resulting in disruption of normal physiological functions and symptoms such as diarrhea, tenesmus, incontinence, and rectal bleeding, which can all significantly alter the patient's quality of life. These patients are at increased risk of developing protein-calorie malnutrition and micronutrient deficiencies. Therefore, designing a proper nutritional intervention plan, with an optimal proportion of protein, fat, and carbohydrates, is required to reduce or even reverse the patients' poor nutritional status, increase their tolerance and response to oncology treatment, decrease the rate of complications and improve their quality of life. The aim of this review was to establish a nutritional plan that includes recommendations on macronutrient proportions and micronutrient intake in patients receiving pelvic radiotherapy. The following nutritional plan has been recommended in the literature: Energy: 28-31 kcal/kg/day, using the Harris-Benedict formula adjusted for body weight in obese patients; protein: 20-30%; fat: 30-40%; and carbohydrates: 40-50%. The maintenance of adequate levels of Vitamin D, Vitamin E, Vitamin A, calcium, magnesium, thiamin, riboflavin, and niacin must be emphasized. Physical activity must also be increased to maintain muscle mass. Nutrient requirements must be established in an integral manner, considering the patient's age, nutritional status, and the presence of comorbidities. Unnecessary dietary restrictions should be avoided to ensure an adequate nutritional status.

ABSTRACT

We evaluated the effects of cisplatin and paclitaxel on taste acuity and their associations with nutritional and health-related quality of life (HRQL) in patients with advanced non-small-cell lung cancer (NSCLC). Forty chemotherapy (CT)-naïve patients were assessed at baseline and after two cycles of paclitaxel and cisplatin. The taste evaluation was performed using a rinsing technique to identify detection and recognition thresholds (DT and RT) of bitter, sweet, and umami tastes. At baseline, 37.5% of the patients reported dysgeusia. After CT, the patients showed lower medians DT (p = 0.017) and RT (p = 0.028) for umami taste. These decreases were associated with clinical neuropathy, worse HRQL, and a tendency toward increased appetite loss. Additionally, CT did not significantly reduce the median DT for sweet (p = 0.09), which is associated with lower intake of protein (p = 0.015), animal protein (p = 0.010), fat (p = 0.004), and iron (p = 0.047). CT decreased the median DT for bitter (p = 0.035); however, this decrease was not associated with nutritional parameters or with HRQL. Sensitivity to taste increased with paclitaxel and cisplatin CT, making foods more unpleasant, and it was associated with neuropathy, worse HRQL, and reduced nutrient intake in advanced NSCLC patients. The protocol was registered at clinicaltrials.gov (NCT01540045).
