Implementation and evaluation of a remote geriatric assessment and intervention program in Brazil.

BACKGROUND: This study sought to determine the feasibility and acceptability of a remote geriatric assessment (GA) and implementation (GAIN) program in Brazil. The authors also explored the effect of this program on health-related quality of life (HR-QOL) outcomes 3 months after initiating treatment. METHODS: This is a longitudinal study enrolling older adults (65+ years), diagnosed with any type of solid tumor, scheduled to initiate chemotherapy in a networked Brazilian cancer center. The GA was performed through telehealth. We assessed the feasibility of the remote GA, acceptability to patients, and changes in patient-centered outcomes (HR-QOL, mood, function) from baseline to month 3. Linear mixed model analysis was done, adjusting for age, gender, race, income, and disease stage. RESULTS: Fifty-six patients completed all intended assessments. Notably, the threshold of feasibility was 70% and there was 92% complete adherence. Average age was 76 years old (SD = 7.2). Most patients were female (57%), married (59%), and had a college degree (46%). The most common diagnoses were gastrointestinal (39%) and gynecological cancers (18%); most were diagnosed at an advance disease stage (77%). A total of 32 patients were referred to a remote appointment and 86% followed this recommendation(s). Significant improvement in Functional Assessment of Cancer Therapy - General FACT-G (mean difference, 6.04; p < .001), Geriatric Depression Scale (mean difference, -0.86; p = .008), and instrumental activities of daily living ratio (mean difference, 0.17; p < .001) were found. CONCLUSION: Remote GAIN is feasible and acceptable to older adults with cancer receiving treatment in Brazil. The authors also found significant improvement in HR-QOL outcomes over time. Notably, this GAIN program could guide early detection of chemotherapy toxicity and improving patient-reported outcomes in low-resource environments.

High Dose Chemotherapy With Autologous Stem Cell Transplant for Patients With Advanced Germ Cell Tumors: Real-World Evidence From a Tertiary Cancer Center in Brazil.

BACKGROUND: High-dose chemotherapy followed by stem cell transplant (HDCT) is potentially curative for patients with refractory germ cell tumors (rGCT). There is scarce real-world data supporting its implementation in low- and middle-income countries. We described the experience of our tertiary cancer center in Sao Paulo, Brazil. METHODS: We identified male patients ≥18 years-old with rGCT referred to HDCT after board discussion. Clinical data, including delays in HDCT protocol, were extracted from medical records, and survival outcomes were estimated using the Kaplan-Meier method. The log-rank test and Cox proportional hazard were used to determine effects on overall survival (OS). RESULTS: From January 2013 to January 2023, 34 patients were referred and considered eligible to receive 2 cycles of HDCT. Most patients had primary testicular tumors (82%), nonseminomatous histology (88%), and poor International Germ Cell Collaborative Group (IGCCCG) (79%). Twenty-three patients received HDCT (1 cycle, n = 8; 2 cycles, n = 15). Main reasons for not receiving any HDCT were death due to progressive disease (n = 1), performance deterioration (n = 7), and failure of stem cell mobilization (n = 3). OS at 2 years was 36.7% for the eligible population, 56.1% for patients who underwent at least 1 HDCT, and 77.1% for those who had ≥2 cycles. The 2-year OS rate for patients not given HDCT was 0%. All patients had delays in protocol, and poor-risk patients had longer intervals from referral to protocol initiation (0.7 vs. 1.8 month, P < .01). CONCLUSION: Outcomes of patients who received ≥1 HDCT were encouraging; however, only 15 from 34 eligible patients were able to receive the planned 2 cycles of HDCT. Further strategies to minimize treatment delays in low- and middle-income countries are needed.

Auditory event-related potentials (P3) and cognitive changes induced by frontal direct current stimulation in alcoholics according to Lesch alcoholism typology.

Frontal lobe dysfunction is a hallmark of alcohol dependence. Recent studies have shown that a simple but powerful technique of cortical modulation--transcranial direct current stimulation (tDCS)--can induce significant cognitive changes. We therefore aimed to assess the clinical and electrophysiological (as indexed by P3) effects of tDCS of left dorsolateral prefrontal cortex (DLPFC) in different types of alcoholic patients according to Lesch's typology. We enrolled 49 alcoholic subjects, aged between 18 and 75 yr, during the subacute abstinence period to participate in this study. Subjects underwent event-related potential (ERP) registration of alcohol-related and neutral sounds before, during and after active tDCS (1 mA, 35 cm², during 10 min) or sham procedure in a counterbalanced and randomized order. Frontal assessment battery (FAB) and five items of the Obsessive Compulsive Drinking Scale were applied at the beginning and at the end of each experimental session. ERP analysis showed an increase in the mean amplitude of P3 associated with alcohol-related sounds after tDCS. This effect was not seen for neutral sounds. This change was more pronounced in Lesch IV alcoholics. Secondary exploratory analysis showed a significant improvement of FAB performance after active tDCS compared to sham tDCS in Lesch IV alcoholics only. We showed clinical and electrophysiological evidence of tDCS-induced frontal activity enhancement that was specific for Lesch IV alcoholics. Given that frontal dysfunction may contribute to the loss of control over drinking behaviour, local increase in frontal activity induced by tDCS might have a beneficial clinical impact in the future.

Hand-foot syndrome caused by capecitabine: incidence, risk factors and the role of dermatological evaluation.

Hand-foot syndrome (HFS), or palmar-plantar erythrodysesthesia, is characterised by erythema, oedema and dysesthesia, which can progress to blistering and ulceration. This condition is described as a common adverse effect of the chemotherapeutic agent capecitabine. The study set out to evaluate real-world incidences; assess severity based on clinical criteria, such as local symptoms, dyschromia, erythema, oedema and ulcerations; and associated factors, such as type of solid tumour, chemotherapy regimen, number of cycles, sex, age and Eastern Cooperative Oncology Group Performance Scale of HFS, related to the use of capecitabine. This is a single-centre prospective cohort study carried out jointly by the departments of clinical oncology and dermatology of a university hospital in the southeast of Brazil. The study showed a 34% incidence of HFS, with most cases classified as mild. There was statistical significance in the correlation of the syndrome with sex and performance scores. HFS is the most common and limiting adverse reaction to capecitabine, and causes significant functional and quality impairments in patients with cancer. With this study, we have reinforced the importance of multidisciplinary assessment for early diagnosis and adequate follow-up.

Unusual presentation of high-grade neuroendocrine carcinoma of the Urinary bladder with small-cell and large-cell features.

High-grade neuroendocrine carcinoma of the urinary bladder comprehends small-cell and large-cell variants. It is a rare and aggressive neoplasm, mostly diagnosed in advanced stages. It is more frequently encountered among Caucasian men in the sixth decade of life. Urinary symptoms are the most common clinical presentation. Diagnosis is generally not troublesome once the lesions are easily detectable by imaging exams and cystoscopy. This neoplasia is associated with tobacco smoking, and is frequently associated with other carcinomatous components such as urothelial carcinoma, adenocarcinoma, and sarcomatoid carcinoma. The authors report a case of an apparently healthy female patient who presented cervical lymph node enlargement not accompanied by systemic symptoms. The supraclavicular lymph node biopsy revealed metastatic small cell carcinoma. The computed tomography scan showed a bladder wall nodular thickening, enlarged lymph nodes along the iliac, periaortic, mediastinal, cervical and supraclavicular chains, as well as an insufflating lytic bone lesion in the right iliac wing. The positron emission tomography-fluorodeoxyglucose (PET-FDG) added to these findings, the presence of a paraesophageal lymph node, lymphadenomegaly in the gluteal region and a vertebral lytic lesion in T10. Resected specimen of the bladder tumor revealed a high-grade neuroendocrine carcinoma with small-cell and large-cell features.
