RESUMO

PURPOSE: Currently, there is no consensus regarding whether super-elderly (aged > 80 years) patients are suitable candidates for laparoscopic surgery. This study aimed to analyse the short-term outcomes and oncological prognosis of laparoscopic gastrectomy in super-elderly patients with gastric cancer (GC). METHODS: Following PRISMA and AMSTAR-2 guidelines, we searched the Web of Science, Embase, Cochrane Library, and Pubmed databases from inception until May 2024 and performed a meta-analysis. All published studies exploring the surgical outcomes and oncological prognosis of laparoscopic versus open gastrectomy in super-elderly patients with GC were reviewed. Statistical analyses were performed using RevMan 5.3. RESULTS: A total of 1,085 studies were retrieved, eight of which were included in the meta-analysis, comprising 807 patients > 80 years of age with GC. The meta-analysis showed that compared with open gastrectomy, patients with GC > 80 years old who underwent laparoscopic gastrectomy had a longer operative time (weighted mean difference [WMD] = 30.48, p < 0.001), less intraoperative blood loss (WMD = -166.96, P < 0.001), shorter postoperative exhaust time (WMD =-0.83, p < 0.001), shorter length of stay (WMD = -0.78, p < 0.001), fewer overall complications (Odds ratio [OR] = 0.54, p = 0.003), higher 5-year overall survival rate (OR = 1.66, p = 0.03) and disease-specific survival rate (OR = 3.23, p < 0.001). Furthermore, laparoscopic gastrectomy did not significantly affect the number of lymph node dissections, the rate of D2 radical gastrectomy, major postoperative complications, or postoperative pneumonia. CONCLUSIONS: Compared to open gastrectomy, patients with GC aged > 80 years who underwent laparoscopic gastrectomy may have better short-term outcomes. Age should not be a contraindication for minimally invasive surgery.

RESUMO

Reminiscence therapy (RT) attenuates psychological disorders in cancer patients. This study aimed to evaluate the effect of RT on anxiety, depression, spiritual well-being, and quality of life in elderly patients with unresectable, metastatic gastrointestinal cancer. A total of 222 elderly patients with unresectable, metastatic gastrointestinal cancer were randomized into RT group (RT plus usual care, n=112) or control group (usual care, n=110) with a 6-month intervention. Hospital Anxiety and Depression Scale for Anxiety (HADS-A) and Depression (HADS-D), Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being Scale (FACIT-Sp), and Quality of Life Questionnaire-Core 30 (QLQ-C30) were evaluated at month (M)0, M1, M3, and M6. Concerning the primary outcome, HADS-A score at M6 decreased in the RT group compared to the control group (P=0.005). As to secondary outcomes, the RT group showed decreased HADS-A scores at M3, anxiety rate at M3, HADS-D scores at M3 and M6, depression rate at M6, as well as greater FACIT-Sp scores at M1, M3, and M6 vs the control group (all P<0.050). Additionally, QLQ-C30 global health score was elevated at M1 (P=0.046) and M6 (P=0.005), functions score was greater at M6 (P=0.038), and symptoms score was lower at M3 (P=0.019) in the RT group than in the control group. Subgroup analysis revealed that the addition of RT was more effective for patients with anxiety or depression at baseline. In summary, RT alleviated anxiety and depression, and improved the spiritual well-being and quality of life within 6 months in elderly patients with unresectable, metastatic gastrointestinal cancer.

RESUMO

Background: In Latin America, epilepsy in the elderly is a neglected issue that has never been studied. The epidemiological transition has significantly altered the demographics of epilepsy, and therefore, we would like to draw attention to this topic. Objective: We require local real-world evidence, as the literature often depicts a different scenario, including pharmacological management. Methods: From 2007 to 2018, we recruited all patients with new-onset geriatric epilepsy (first seizure after the age of 60) tracked from ten Mexican hospitals, adding them to patients with similar characteristics from a previously published study. The diagnosis was confirmed in all patients by a certified neurologist, and they were also studied using a conventional electroencephalogram and imaging workup. Results: A diagnosis of new-onset geriatric epilepsy (Elderly patients was established in 100 cases. No specific cause was found in 26% of patients, while 42% had a stroke and 10% had neurocysticercosis (NCC). Monotherapy was the choice in 83 patients, and phenytoin was the most used drug (50%), followed by carbamazepine (25%). Conclusion: NCC remains a frequent cause of new-onset geriatric epilepsy. This distribution is not seen in the literature, mainly representing patients from wealthy economies. In our setting, financial constraints influence the choice of the drug, and newer antiepileptic drugs should be made more affordable to this population with economic and physical frailty.

RESUMO

INTRODUCTION: The age for kidney transplantation (KT) is no longer a limitation and several studies have shown benefits in the survival of elderly patients. The aim of this study was to examine the relationship of the baseline Charlson comorbidity index (CCI) score to morbidity and mortality after transplantation. METHODS: In this multicentric observational retrospective cohort study, we included patients older than 60 years admitted on the waiting list (WL) for deceased donor KT from January 01, 2006, to December 31, 2016. The CCI score was calculated for each patient at inclusion on the WL. RESULTS: Data for analysis were available of 387 patients. The patients were divided in tertiles of CCI: group 1 (CCI: 1-2) n = 117, group 2 (CCI: 3-4) n = 158, and group 3 (CCI: ≥5) n = 112. Patient survival was significantly different between CCI groups at 1, 3, and 5 years, respectively: 90%, 88%, and 84% for group 1, 88%, 80%, and 72% for group 2, and 87%, 75%, and 63% for group 3 (p < 0.0001). Variables associated with mortality were CCI score (p < 0.0001), HLA mismatch (p = 0.014), length of hospital stay (p < 0.0001), surgical complications (p = 0.048). CONCLUSION: Individualized strategies to modify these variables may improve patient's morbidity and mortality after KT.

RESUMO

Population's aging leads to a frequent usage of pharmaceutical medications to treat or control various ailments because of aging, increasing the probability of occurrence of problems related to its usage. The primary objective of this study was to conduct pharmaceutical interventions in elderly patients from San Luis - Riobamba, using surveys to identify the sociodemographic characteristics, diseases, and medicines usage. Once the problems related to pharmacological therapy were identified, pharmaceutical interventions were carried our prior the acceptance of each patient. The study had the participation of 422 elderly patients, with the prevalence of females (59.7%), aged between 60 and 70 years (45.5%); we identified that 82.5% of the elderly patients have diseases, finding that joint pain such as Arthritis/Osteoarthritis has the higher incidence (38.8%), and 50% of the surveyed people consume medication to treat the disease. 40.28% (n=170) of the participants conciliate the treatment review to identify any medication-related problem (MRP), finding interactions (21.2%) and adverse effects probability (21.2%), starting from the PRM identified, 170 pharmaceutical interventions were conducted, considering as priority (67.6%) the education on non-pharmacological measures. The pharmaceutical interventions done through the study benefited the elderly patients and will contribute to reduce the appearance of PRM.

RESUMO

RESUMEN Antecedentes: debido al aumento en la expectativa de vida, se ha incrementado la incidencia de tumores de cabeza y cuello en pacientes añosos. Objetivo: evaluar los resultados de la reconstrucción con colgajos microquirúrgicos luego de la resección radical (RRMC) de tumores de cabeza y cuello en pacientes de 70 años o mayores. Material y métodos: se analizó una serie de pacientes sometidos a RRCM por tumores de cabeza y cuello en el período 2000-2020. Se dividió la muestra en dos grupos: G1: ≥ de 70 años y G2: < de 70 años. Se analizaron variables demográficas, quirúrgicas, posoperatorias y factores de riesgo de trombosis del colgajo en los pacientes ≥ de 70 años. Resultados: se incluyó un total de 178 pacientes, 61 en G1 y 117 en G2. Ambos grupos fueron homogéneos respecto del sexo, IMC (índice de masa corporal), alcoholismo, tabaquismo, tratamiento neoadyuvante e incidencia de HPV (virus del papiloma humano). Hubo mayor cantidad de pacientes con riesgo ASA ≥ III en G1 vs. G2; (p: 0,005). En G1, 33 (54%) correspondieron a estadio oncológico ≥ III vs. 99 (87%) en G2 (p: 0,001). Cuarenta y dos (69%) pacientes en G1 recibieron adyuvancia vs. 94 (83%) en G2 (p: 0,02) y no hubo diferencias en la morbimortalidad global y en fallas del colgajo. El sexo femenino fue el único factor de riesgo de trombosis del pedículo vascular (p: 0,05). Conclusión: la RRCM para tumores de cabeza y cuello es factible y segura en pacientes añosos, con una incidencia de morbimortalidad similar a la del resto de la población.

ABSTRACT Background: The higher life expectancy has increased the incidence of head and neck tumors in elder patients. Objective: the aim of this study was to evaluate the outcomes of free flap reconstructions after radical resection (FFRR) of head and neck tumors in patients aged 70 years or older. Material and methods: We analyzed a series of patients undergoing FFR due to head and neck tumors between 2000-2020. The patients were divided into two groups: G1: ≥ 70 years, and G2: < 70 years. The demographic, operative and postoperative variables and the risk factors for flap thrombosis in patients ≥ 70 years were analyzed. Results: A total of 178 patients were included, 61 in G1 and 117 in G2. Both groups were homogeneous regarding sex, BMI (body mass index), alcohol consumption, smoking habits, neoadjuvant treatment, and incidence of HPV (human papillomavirus). The incidence of ASA grade ≥ III was significantly higher in G1 vs. G2; (p: 0,005). In G1, 33 patients (54%) corresponded to cancer stage ≥ III vs. 99 (87%) in G2 (p: 0.001). Forty-two (69%) patients in G1 received adjuvant therapy vs. 94 (83%) in G2 (p = 0.02) and there were no differences in overall morbidity and mortality and in flap failure. Female sex was the only predictor of vascular flap thrombosis (p = 0.05). Conclusion: FFRR in head and neck tumors is feasible and safe in elderly patients, with morbidity and mortality rates similar to those of the general population.

RESUMO

The blood levels of neutrophils are associated with the severity of COVID -19. However, their role in the pulmonary environment during COVID -19 severity is not clear. Here, we found a decrease in the neutrophil count in BAL (bronchoalveolar lavage) in non-survivors and in older patients (> 60 years). In addition, we have shown that older patients have higher serum concentration of CXCL8 and increased IL-10 expression by neutrophils.

RESUMO

The aim of this study was to compare the clinical effectiveness and complications of different treatment modalities for elderly patients with distal radius fracture (DRF). METHODS: We performed a network meta-analysis (NMA) of randomized clinical trials (RCTs). Eight databases were searched. The eligibility criteria for selecting studies were RCTs that compared different treatment modalities (surgical or nonoperative) in patients older than 60 years with displaced or unstable intra-articular and/or extra-articular DRFs. RESULTS: Twenty-three RCTs met the eligibility criteria (2020 patients). For indirect comparisons, the main findings of the NMA were in volar locking plate (VLP) versus cast immobilization, with the mean differences for the patient-rated wrist evaluation (PRWE) questionnaire at -4.45 points (p < 0.05) and grip strength at 6.11% (p < 0.05). Additionally, VLP showed a lower risk ratio (RR) of minor complications than dorsal plate fixation (RR: 0.02) and bridging external fixation (RR: 0.25). Conversely, VLP and dorsal plate fixation showed higher rates of major complications. CONCLUSIONS: Compared with other treatment modalities, VLP showed statistically significant differences for some functional outcomes; however, most differences were not clinically relevant. For complications, although most differences were not statistically significant, VLP was the treatment modality that reported the lowest rate of minor and overall complications but also showed one of the highest rates of major complications in these patients.

RESUMO

Abstract: Introduction: Depressive symptoms are common in elderly surgical patients and are associated with negative outcomes. Although medication can relieve symptoms, only 50% of patients achieve remission using conventional treatments. Recently, ketamine has been shown to improve depression rapidly. However, its use and tolerability in elderly patients has not been widely studied. Material and methods: We conducted a randomized, double-blind, comparative study in patients aged 60 and over who required ophthalmological surgery. Experimental group received 0.5 mg/kg ketamine, whereas the control group received NaCl solution at 0.9%. Both groups received a standardized regimen of conscious sedation. Depressive symptom severity was assessed using the Geriatric Depression Scale-Short Form (GDS-SF) before and after exposure to ketamine infusion; tolerability was also evaluated. A repeated univariate analysis of variance (ANOVA) model examined the direction of changes in depressive symptom severity among groups. Results: 90 patients were randomized. A significant reduction in symptom severity was observed after ketamine infusion (mean change from baseline: -1.6 vs -0.3 in the control group; p = 0.003). No differences emerged between groups in the presence of adverse effects with ketamine infusion. Conclusions: A single infusion of ketamine in elderly patients undergoing ophthalmological surgery is associated with improved depressive symptoms in the first 24 hours of exposure to the drug with a good tolerability profile.

Resumen: Introducción: Los síntomas depresivos son comunes en pacientes quirúrgicos de edad avanzada y se asocian con resultados negativos. Aunque la medicación pueda aliviar los síntomas, sólo el 50% de los pacientes que están envejeciendo alcanzan la remisión usando tratamientos convencionales. Se ha demostrado que la ketamina mejora rápidamente la depresión, sin embargo, su uso y tolerabilidad en pacientes mayores no ha sido estudiada ampliamente. Material y métodos: Se realizó un estudio aleatorizado, doble ciego, comparativo en pacientes de 60 años o más que requirieron cirugía oftalmológica. Un grupo experimental recibió 0.5 mg/kg de ketamina, mientras que el grupo control recibió solución de NaCl al 0.9%. Ambos grupos recibieron un régimen estandarizado de sedación consciente. La severidad de los síntomas depresivos fue evaluada usando la versión acortada de la escala de depresión geriátrica (GDS-SF) antes y después de la exposición a la infusión de la ketamina, la tolerabilidad también fue evaluada. Un modelo de análisis de varianza univariada de medidas repetidas (ANOVA) examinó la dirección de los cambios en la gravedad de los síntomas depresivos entre los grupos. Resultados: 90 pacientes fueron aleatorizados. Se observó, una reducción significativa en la severidad de los síntomas después de la infusión de la ketamina (cambio de la media desde el valor basal: -1.6 versus -0.3 en el grupo de control; p = 0.003). No surgieron diferencias entre los grupos en la presencia de efectos adversos con la infusión de ketamina. Conclusiones: Una sola infusión de ketamina en pacientes geriátricos sometidos a cirugía oftalmológica se asocia con la mejoría de síntomas depresivos en las primeras 24 horas de exposición al fármaco con un buen perfil de tolerabilidad.

RESUMO

BACKGROUND: Although D2-gastrectomy is the most effective treatment for resectable gastric cancer (GC), it is unclear whether elderly patients have increased risk of morbidity and worse survival. This study aimed to compare the short- and long-term outcomes of older age (OA) patients with those of less advanced age (LAA). METHODS: GC patients undergoing curative gastrectomy were retrospectively analyzed and divided into two groups: OA (>75 years) and LAA (<75 years). Propensity score-matching (PSM) analysis using seven variables was conducted to reduce selection bias. RESULTS: Among 586 patients, 494 (84.3%) were classified as LAA and 92 (15.7%) as OA. OA patients had worse clinical status, higher rates of D1-lymphadenectomy, subtotal gastrectomy, and Lauren type; higher mortality and worse survival. No difference in pathological tumor-node-metastasis (pTNM) stage was observed between groups. Preoperative chemotherapy was performed more frequently in the LAA group. After PSM (92 OA: 92 LAA), all variables included in PSM were matched, and mortality rates and survival became similar between groups. In multivariate analysis, American Society of Anaesthesiologists score III/IV was an independent factor associated with a 90-day mortality after PSM. CONCLUSION: Gastrectomy in elderly GC patients has similar outcomes compared with younger ones. Clinical status and disease stage are more important than the patient's age.

RESUMO

ABSTRACT Background The prevalence of hospitalized elderly patients has grown substantially and has impacted the hospital health services. Thus, it is believed that an investigation of the nutritional status associated with different clinical situations in elderly patients could contribute to multidisciplinary hospital intervention and nutritional care actions suitable for this population. Objective To investigate the relationship between two nutritional screening instruments in hospitalized older patients and to compare clinical variables between these two instruments. Methods Retrospective study with hospitalized older patients (n=277), investigating the agreement between two nutritional screening instruments. The data were analyzed using the McNemar, chi-square, Fisher, Mann-Whitney tests and the kappa coefficient for the agreement assessment. Results There was a significant difference (P=0.0002) between the nutritional risk classifications of the two nutritional screening instruments and moderate agreement (k=0.5430) between them. The association between nutritional risk screening and age (P=0.0255), length of hospital stay (P<0.0001), gender (P=0.0365) and illness (P=0.0001) were assessed. There was an association between Mini Nutritional Assessment and length of stay (P<0.0001), illness (P=0.0001) and body weight evolution (P=0.0479). Conclusion The nutritional risk screening and Mini Nutritional Assessment showed moderate agreement in the assessment of elderly patients.

Conclusão Triagem de risco nutricional e a Mini Avaliação Nutricional apresentam concordância moderada para a avaliação de pacientes idosos.

RESUMO

BACKGROUND: The prevalence of malnutrition in hospitalized elderly patients (HEP) is high. OBJECTIVE: To investigate the behavior of several nutritional indicators and predictors of unfavorable clinical outcome. METHODS: Retrospective study with hospitalized elderly patients (N = 322). Nutritional instruments, indicators and outcome were investigated. Chi-square, Fisher and Mann-Whitney tests and univariate and multiple logistic regression analysis were used. RESULTS: The variables that, jointly, were associated with hospital stay longer than 7 days, include: the presence of complications (p = 0.0328; OR 1.946; IC95% 1.056; 3.585) and nutritional risk according to the NRS-2002 (p = 0.0016; OR 2.080; IC95% 1.322; 3.275). The variable that remained associated with complications in the multiple model was the nutritional risk according to the NRS-2002 (p = 0.0018; OR 2.587; IC95% 1.423; 4.703). CONCLUSION: Nutritional risk using the NRS-2002 is a predictor of clinical outcome in hospitalized elderly patients.

RESUMO

Nephrotic syndrome is the most common clinical presentation of glomerular disease in elderly patients, and renal biopsy is an important diagnostic resource. The aim of this study was to describe nephrotic syndrome among elderly patients in Brazil, focusing on tubulointerstitial and vascular involvement. This was a retrospective study of patients over 65 years of age with nephrotic syndrome who underwent renal biopsy between January 2012 and December 2019. Of the 123 renal biopsies that occurred during the study period, 44 (35.8%) were performed for the investigation of nephrotic syndrome. Among those 44 cases, the main etiologies were membranous nephropathy in 13 cases (29.5%), amyloidosis in ten (22.7%), non-collapsing focal segmental glomerulosclerosis (FSGS) in four (9.1%), and collapsing FSGS in four (9.1%). Patients with minimal change disease (MCD) had the lowest degree of interstitial fibrosis compared with the other glomerulopathies, and histological signs of acute tubular necrosis (ATN) were less common among those with amyloidosis than among those with membranous nephropathy, FSGS, or MCD (P=0.0077). Of the patients with ATN, the frequency of acute kidney injury (AKI) was highest in those with MCD (P<0.001). All patients had some degree of vascular involvement, regardless of the type of glomerulopathy. In conclusion, the second most common cause of nephrotic syndrome in this population was amyloidosis, and acute interstitial tubule involvement was more marked in MCD. Vascular involvement is something that cannot be dissociated from the age of the patient and is not only due to the underlying glomerulopathy.

RESUMO

Adenine nucleotides are important signaling molecules that mediate biological functions in many conditions, including cancer. The enzymes CD39 and CD73 produce adenosine in the extracellular milieu that has a very important role in tumor development. This study aimed to evaluate nucleotide hydrolysis in the plasma blood of breast cancer elderly patients. In this prospective cohort study, we investigated the ectonucleotidases activity in breast cancer elderly patients, at the moment of diagnosis and after treatment. Control group consisted of elderly women without cancer diagnostic. The nucleotide hydrolysis assay was performed by the malachite green method and used ATP, ADP, or AMP as substrates. Paired t test or Wilcoxon rank-sum test was used. Our data showed that breast cancer patients presented high levels of ATP and AMP hydrolyses when compared to control group at the moment of diagnosis. When analyzing the differences between the samples at the time of diagnostic and 6 months after treatment, we observed a significant reduction on CD73 activity after all treatments used: surgery, chemotherapy, radiotherapy, or hormone therapy. The results with APCP, a specific CD73 inhibitor, showed that the AMP hydrolysis was inhibited in all conditions evaluated. We observed a diminished ADPase activity in the patients without metastasis when compared to metastatic breast cancer patients. The results showed that AMP hydrolysis was reduced in the blood plasma of breast cancer elderly patients after different treatments. This study strengthens the potential role of CD73 enzyme as a biomarker for breast cancer treatment response.

RESUMO

BACKGROUND: Unhealthy teeth can seriously affect general health and increase the risk of death in elderly people. There has been no confirmation of which device is most effective for elderly patients with teeth loss. Therefore, we compared four intubation devices in elderly patients with partial and total tooth loss aiming to reduce risk during anesthesia. METHODS: Two hundred patients were randomized to undergo tracheal intubation with the Macintosh laryngoscope, the Glidescope, the Fiberoptic bronchoscope or the Lightwand as part of general anesthesia. A unified protocol of anesthetic medications was used. HR and BP were measured at T0, T1, T2, T3, T4 and T5. Catecholamine (epinephrine and norepinephrine) blood samples were drawn at T0, T1 and T2. Intubation time and postoperative complications, including dental damage and losses, were recorded. RESULTS: Reduced fluctuations in HR, DBP, and SBP were observed in the Lightwand group. Intubation time was significantly shorter in the Lightwand group (p < 0.05). There was no statistically significant difference between the groups in epinephrine levels, but norepinephrine levels were less volatile in the Fiberoptic bronchoscope and Lightwand groups. Fewer patients in the Lightwand group experienced dental damage and other postoperative complications than in the other three groups. Although a higher success rate on the first attempt was as high as in the Fiberoptic bronchoscope group, shorter intubation time was observed only in the Lightwand group. CONCLUSION: The Lightwand offers less hemodynamic stimulation than the Macintosh laryngoscope, Glidescope, and Fiberoptic bronchoscope. Because it had the shortest intubation time, the Lightwand caused the least damage to the teeth and throat of elderly patients. Our findings showed that tracheal intubation with the Lightwand was advantageous for preventing cardiovascular stress responses with short intubation times and fewer postoperative complications.

RESUMO

INTRODUCTION: In melanoma, lymph node status constitutes the most important prognostic factor among patients with locoregional disease. It has been postulated that elderly patients present less metastatic involvement in sentinel lymph node (SLN). Our objective was to analyse the results and evolution of patients ≥ 70 years-old with cutaneous melanoma in whom sentinel lymph node biopsy (SLNB) was carried out. METHODS: Retrospective analysis of 194 patients with primary CM who had a SLNB between 2005 and 2020 was included. Demographic and tumour data, SLN status, recurrence rate, morbidity and evolution were evaluated. Patients were divided into two groups according to age: Group 1 (<70 years old) and Group 2 (≥70 years old). RESULTS: One hundred and fifty patients were included in Group 1 and 44 patients in Group 2. Median Breslow thickness was 1.7 mm in Group 1 and of 2 mm in Group 2 (p = 0.015).Forty-seven patients had positive SLNB; 38 (25%) belonged to Group 1 and 9 (20.5%) to Group 2 (p = 0.55). Recurrence was found in 34 patients: 25 belonging to Group 1 and 9 corresponding to Group 2 (p = 0.65). Morbidity was of 4% in Group 1 and 9% in Group 2 (p = 0.23). With an average follow-up of 30.6 months, 5-year overall survival was of 87% in Group 1 and of 63% in Group 2 (p = 0.04). CONCLUSION: Advanced age was not associated with differences regarding positivity of SLN and recurrence but difference in overall survival was observed. According to our results and the low morbidity rate, we consider SLNB should not be omitted in such age group, since it improves staging and gives the possibility to evaluate adjuvant treatment.

RESUMO

PURPOSE: To investigate the application value of serum CXC Chemokine-13 (CXCL-13) and platelet endothelial cell adhesion molecule-1 (PECAM-1) in elderly patients with gastric cancer (GC). METHODS: Ninety-eight elderly GC patients admitted to the Affiliated Hexian Memorial Hospital of Southern Medical University were selected as a research group, and 60 healthy subjects of the same age and in relatively good health who underwent physical examination at the same period were selected as a control group. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of CXCL13 and PECAM-1 in serum. The clinical diagnosis and prognostic value of serum CXCL13 and PECAM-1 in elderly GC patients were analyzed. RESULTS: The levels of CXCL13 and PECAM-1 in serum of the research group were significantly higher than those of the control group (P < 0.001). The AUC value of combined diagnosis of elderly GC patients by serum CXCL13 and PECAM-1 was 0.950, and that of combined evaluation of prognosis of patients was 0.849. Serum CXCL13 and PECAM-1 were significantly related to TNM staging, differentiation degree and tumor diameter in elderly GC patients (P < 0.05). High levels of CXCL13 and PECAM-1 were significantly associated with lower 5-year OS (P < 0.05). CONCLUSION: Elderly GC patients with higher TNM staging, longer tumor diameters, high levels of CXCL13 and PECAM-1 had an increased risk of poor prognosis. Serum CXCL13 and PECAM-1 can be used as effective indicators for diagnosis and prognosis of elderly patients with GC, and can predict the 5-year OS in patients.

RESUMO

PURPOSE: Weekly irradiation in breast cancer in elderly patients is a treatment option, whose tolerance may be influenced by the fractionation used. The objective of this study is to compare the tolerance and long-term side effects of two different fractionations. MATERIALS AND METHODS: 47 elderly patients were recruited after conservative or radical treatment that also received irradiation with a dose per fraction of 6.25 Gy or 5 Gy for one session per week, 6 sessions in total. The long-term tolerance results are compared by assessing toxicity using CTCAE version 5.0 scales for dermatitis, telangectasia, fibrosis and pain of the irradiated breast. In addition, objective parameters of skin status (erythema, hyperpigmentation, elasticity and hydration) by a multi-probe MultiSkin Test-Center system were obtained and compared between groups. RESULTS: After an average follow-up of 5 years, all patients were free of disease and with complete local control. A total of 20 patients with 6.25 Gy fractionation and 27 patients with 5 Gy fractionation have been included. Patients treated with lower fractionation had a lower incidence of dermatitis, telangectasia, fibrosis, or local pain. The decrease in elasticity measured by the multi-probe system was smaller with the fractionation of 5 Gy. No differences were observed in the other objective parameters. CONCLUSION: Weekly irradiation with 5 Gy fractionation is better tolerated than with higher fractionation.
