RESUMO
BACKGROUND: Disparities in the timely diagnosis and care of cancer patients, particularly concerning geographical, racial/ethnic, and economic factors, remain a global health challenge. This study explores the multifaceted interplay between socioeconomic status, health literacy, and specific patient perceptions regarding care access and treatment options that impact cancer care in Uruguay. METHODS: Using the Cancer Health Literacy Test, Spanish Version (CHLT-30-DKspa), and a highly comprehensive questionnaire, we dissected the factors influencing the pathway to diagnosis and route of cancer care. This was done to identify delays by analyzing diverse socioeconomic and sex subgroups across multiple healthcare settings. RESULTS: Patients with lower income took longer to get an appointment after showing symptoms (p = 0.02) and longer to get a diagnosis after having an appointment (p = 0.037). Race/ethnicity also had a significant impact on the length of time from symptoms to first appointment (p =0.019), whereas employment status had a significant impact on patients being susceptible to diagnostic delays beyond the advocated 14-day window (p = 0.02). Higher educational levels were positively associated with increased cancer health literacy scores (p = 0.043), revealing the potential to mitigate delays through health literacy-boosting initiatives. Women had significantly higher self-reported symptom duration before seeking an intervention (p = 0.022). We also found many other significant factors effecting treatment delays and cancer health literacy. CONCLUSIONS: While affirming the global pertinence of socioeconomic- and literacy-focused interventions in enhancing cancer care, the findings underscore a complex, gendered, and perceptually influenced healthcare navigation journey. The results highlight the urgent necessity for strategically crafted, globally relevant interventions that transcend equitable access to integrate literacy, gender sensitivity, and patient-perception alignments in pursuit of optimized global cancer care outcomes.

Malignant pleural effusion (MPE) is an indicator of advanced disease (stage M1a) in patients with non-small cell lung cancer (NSCLC). Typically, these patients are candidates for palliative treatment. There is a lack of evidence about the radical surgical treatment in carcinomatous pleuritis with massive effusion. Here, we present data from a specific subset of patients with MPE treated with systemic therapy and aggressive surgical therapy. M1a NSCLC adenocarcinoma patients with MPE and without extra-thoracic disease were included. After receiving systemic therapy, all patients underwent surgical treatment, which included pneumonectomy or lobectomy, plus mediastinal dissection. Following surgery, patients received radiotherapy to thoracic wall and mediastinum. A total of six patients were analyzed. All patients had an Eastern Cooperative Oncology Group (ECOG) performance status ≤1, two patients harbored EGFR mutation and were treated with tyrosine kinase inhibitors (TKIs), the other four patients were treated with pemetrexed and platin as first-line treatment. Following systemic therapy, two patients had a pneumonectomy, four patients had a lobectomy plus pleurectomy performed. All patients continued with maintenance systemic therapy, and achieved complete responses, according to RECIST 1.1 criteria. The media progression-free survival (PFS) time was 15.9 months (95% CI: 15.6-55.5 months). At the last follow-up, all patients were still alive, with 4 of them without signs of macroscopic tumoral activity. The median overall survival (OS) was not reached. NSCLC patients with MPE without extra-thoracic disease could benefit from an aggressive surgical approach following standard of care systemic therapy. However, considering the low sample size of this study and the relatively low incidence of MPE without extra-thoracic disease, further prospective multi-center studies are necessary to evaluate aggressive surgery as a therapeutic option.
RESUMO
BACKGROUND: This case report assesses the effectiveness of surgery plus pirfenidone (PFD) as a concomitant therapy in the management of facial trauma after severe dog bite. METHODS: A 16-month-old female patient who suffered a severe attack by a big-sized dog (Rottweiler) in the midface area was managed with surgery/PFD combination and followed up for 20 months to evaluate the efficacy to control, prevent, and improve injury sequels. RESULTS: Surgery/PFD combination offered a good complementary therapy downregulating inflammatory activity, improving blood supply, and activating cytokine modulation and collagen synthesis/biosynthesis (scar control). No side effects were reported in this case report. CONCLUSIONS: Surgery/PFD management for severe facial dog bites represents a safe and effective therapeutic option to protect and improve a patient's quality of life, minimizing long-time sequels.

This article is based on the case of a 28-year-old woman who was involved in a car accident, with diagnosis of polytrauma, loss of left eye, and second- and third-degree burns over the left midface, rendering an exposed area of 8 cm wide and 19 cm length, ranging from glabella to mandible, with skull exposure and loss of left eye.A latissimus dorsi musculocutaneous free flap was transferred into the defect; left eye and nose prosthetics were necessary to restore normal appearance. Excellent results were obtained; reinsertion to patient's normal life and reinstatement of facial appearance were achieved with minimal costs and no postsurgical complications.Analysis of the current situation in developing countries demonstrates that technique and infrastructure do not represent a real challenge to carry on face transplants. However, socioeconomic reality in these societies makes it difficult to establish face transplant as a feasible therapeutic opportunity for the overwhelming majority of patients who are victims of severe facial damage.Therefore, strategies such as latissimus dorsi free flap remains as an excellent therapy to face off our complex facial reconstructive challenges in developing countries such as Mexico.

BACKGROUND: Hepatocellular carcinoma is the third leading cause of cancer death. Single or multiple mutations in genes related to growth control, apoptosis, invasion and metastasis have been determined; so a better understanding of the molecular genetic basis of malignant transformation, tumor progression and host interaction has led to significant progress in the development of new therapeutic agents. The ability of adenovirus vectors to deliver and express genes at high yields in HCC treatment has been demonstrated and well documented over the last few years. OBJECTIVE: To overview and provide an update of what has been accomplished in the field of adenoviral gene therapy and its application in hepatocellular carcinoma treatment. METHODS: Original articles were searched using Pubmed and other medical databases to get the most representative and actual information to establish the current state of the investigation of Ad vectors in HCC. RESULTS: Good results have been accomplished in preclinical models using new Ad vectors and especially AAV vectors, it is important to motivate further clinical trials to corroborate all the experience obtained. CONCLUSIONS: Ad and AAV must be considered as an opportunity to improve the quality of life and survival of HCC patients.
RESUMO
BACKGROUND: Breast capsular contracture (BCC) is a commonly adverse event postmammoplastly characterized by an immune response mediated by cytokines and transforming growth factor (TGF)-ß1 resulting in excessive synthesis and deposit of extracellular matrix around the breast implant. Presence of TGF-ß1 polymorphisms has been associated as a risk factor to develop fibroproliferative diseases. METHODS: This open, controlled, prospective, and pilot clinical trial with 6 months duration was carried out to evaluate the efficacy of 1800 mg a day, of oral Pirfenidone (PFD) in the treatment of BCC (Baker Score III/IV) postmammoplasty. Twenty BCC cases received PFD and 14 BCC control cases underwent capsulectomy after 6 months of enrollment. Both groups were followed up for 6 more months up to 12 months to determine the relapse in the absence of PFD. Determination of TGF-ß1 polymorphisms was performed to establish a correlation with capsular contracture. RESULTS: PFD group experienced BCC-reduction in all breasts 6 months after enrollment. Only 1 of 20 cases relapsed after follow-up. In capsulectomy group, 2 of 14 cases presented progression to grade IV during presurgical period. All capsulectomy cases relapsed at end of follow-up. Nearly hundred percent of all patients studied in this protocol had a profibrogenic homozygous TGF-ß1 polymorphism (codon 25; genotype Arg25Arg). CONCLUSIONS: PFD is useful to improve BCC (Baker Score III/IV) postmammoplasty with no relapse after drug administration. There is also an association between capsular contracture and the presence of homozygous G/G TGF-ß1 genotype.

BACKGROUND: Pathologic skin scarring reversion remains a big challenge for surgeons, as disfiguring scars have a dramatic influence on patient's quality of life. METHODS: A controlled clinical trial was conducted to evaluate 8% pirfenidone (PFD) gel administered topically 3 times a day during 6 months to 33 pediatric patients with hypertrophic scars caused by burns. A total of 30 patients with hypertrophic scars with identical Vancouver Scar Scale values were treated with pressure therapy and included as controls. Improvements were evaluated by Vancouver Scar Scale and a Visual Analog Scale. Safety parameters were determined by the presence of adverse events and monitoring laboratory and hematology parameters. RESULTS: Patients treated with PFD during 6 months presented a continuous monthly statistically significant scar regression in comparison with the initial Vancouver measurement (P = <0.001). PFD group showed a higher improvement of all scar features as compared with control group treated with pressure therapy (P = <0.001). In the PFD group, 9 of 33 patients (27%) had their scores decreased in Vancouver classification by more than 55%, 22 patients (67%) had a 30% to 45% decrease, whereas 2 patients (6%) had a 30% decrease or less. Control group treated with pressure therapy showed a slight improvement in 16% of cases on an average. Patients did not show serious adverse effects or laboratory alterations throughout the study. CONCLUSIONS: Topical administration of 8% PFD gel 3 times a day is more effective and safe in the treatment of hypertrophic scars caused by burns in children, as compared with standard pressure therapy.
