Inactivation of the cyclin-dependent kinase inhibitor 2A (CDKN2A) gene is considerably more frequent in squamous cell lung cancer (SqCLC) than in other subtypes of lung cancer and may be a promising ...target for this histology. Here, we present the course of diagnosis and treatment of a patient with advanced SqCLC, harboring not only CDKN2A mutation but also PIK3CA amplification, Tumor Mutational Burden-High (>10 mutations/megabase), and a Tumor Proportion Score of 80%. After disease progression on multiple lines of chemotherapy and immunotherapy, he responded favorably to treatment with the CDK4/6i Abemaciclib and later achieved a durable partial response to immunotherapy rechallenge with a combination of anti-PD-1 and anti-CTLA-4, nivolumab, and ipilimumab.
ABSTRACTRecent advances in the understanding of tumor driver mutations, signaling pathways that lead to tumor progression, and the better understanding of the interaction between tumor cells and the ...immune system are revolutionizing cancer treatment. The pace at which new treatments are approved and the prices at which they are set have made it even more difficult to offer these treatments in countries like Brazil. In this review we present for the non-oncologist these new treatments and compare their availability in Brazilian public health system and private health system with that of developed countries.RESUMOAvanços recentes na compreensão de mutações promotoras de desenvolvimento do câncer, sinalização que leva à progressão de tumores, e o avanço no entendimento da interação entre as células tumorais e o sistema imunológico estão revolucionando o tratamento do câncer. A velocidade com que novos tratamentos são aprovados e o alto custo das medicações dificultam a disponibilização de terapêuticas em países como o Brasil. Nesta revisão, apresentamos ao não oncologista esses novos tratamentos e comparamos sua disponibilidade nos sistemas público e privado de saúde no Brasil com os países desenvolvidos.
To evaluate the impact of COVID-19 pandemic on the care delivered to hospitalized cancer patients in end-of-life.
A retrospective analysis of data of hospitalized patients with advanced solid tumors, ...who died under exclusive palliative care during first wave (March 2020 to July 2020) compared with the period previous pandemic (January 2018 to February 2020).
A total of 190 oncologic patients were included, 161 patients before the pandemic, and 29 in the period from March 2020 to July 2020. The average hospitalization was 497.2 patients per month, before the pandemic, and dropped to an average of 46.5 in the pandemic, whereas the death rate decreased from an average of 6.3 patients per month to 4.8. Considering the benchmarks for quality of care during end-of-life care, preferences on life assistance were discussed prior to hospitalization for 34.4%, before the pandemic, and 13.8% during the pandemic (p=0.0298); 9.3% received chemotherapy 15 days prior to the date of death, before the pandemic, and 20.7%, in the pandemic (p=0.1012).
Based on the present results, despite the decrease in oncology admissions, the advanced-stage cancer patients continued to seek hospital for end-of-life care. However, we could observe in our benchmarking analyses for palliative quality of care that talks about prognosis occurred less often during the pandemic.
Primary transitional cell carcinoma of the ureter is a rare type of cancer with metastasis presented in approximately 25% at diagnosis. Due to its rarity and poor prognosis, the management of this ...neoplasm is still controversial, and the development of new therapies is of uttermost importance. Herein, we describe a case of a 54-year-old patient diagnosed with transitional cell carcinoma of the left ureter submitted to left nephroureterectomy (pT3N2M0) and methotrexate, vinblastine, doxorubicin, and cisplatin adjuvant chemotherapy. A single liver metastasis was detected and combination chemotherapy with gemcitabine and carboplatin was initiated along with stereotactic body radiation therapy. Despite these 2 previous chemotherapy regimens, the patient presented disease progression and transarterial selective internal radiation therapy (SIRT) with yttrium-90 was indicated. This locoregional treatment was performed with the administration of 1.2 GBq yttrium-90 resin microspheres (SIR-Spheres ® , Sirtex Medical Limited, Sydney, NSW, Australia) into the right hepatic artery. Another systemic treatment was immunotherapy using nivolumab with excellent tolerability. After 10 years of follow-up, at the last clinical evaluation, the patient had no clinical symptoms and the last imaging follow-up using positron emission tomography-computed tomography scan showed complete response. This report introduces upper urinary tract urothelial carcinoma as a distinct type of malignancy in which SIRT can be safely implemented. As a transition method to nivolumab, it was successful. There might be a potential therapeutic synergism between these 2 treatment modalities.
Targeted and immunotherapy have revolutionized cancer treatment. They safely substitute for traditional chemotherapy in a significant and growing number of malignancies. In this article, we review ...the United States Food and Drug Administration (FDA) - approved targeted and immunotherapies, currently used in oncology and compare their safety and efficacy in young versus geriatric and frail sub-population. The results suggest an overall comparable, if not superior efficacy in several tumor types, with acceptable toxicities across the board compared to cytotoxic chemotherapy and a favorable analysis in the comparison to the results observed in the younger population. The very decision to place elderly patients on exclusive palliative care can no longer be supported based on age or frailty alone. The historical concept of medical oncologists leaning for palliative treatments for these patients needs to be revisited.
Purpose of the Study: Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoid malignancy worldwide. Its incidence increases with age and about 40% of cases occur in patients over 70 years. ...Herein, we describe a case of a frail elderly patient with renal insufficiency and DLBCL treated with R-mini-CHOP. Case Report: A 77-year-old man on maintenance hemodialysis started experiencing persistent fatigue. He was diagnosed with a large mass on the left lobe of the lung. Biopsy demonstrated a DLBCL, CD20 positive. The patient was assigned clinical stage IIBX, with a high age-adjusted international prognosis index. A proper geriatric assessment revealed a frail patient. Thus, an adapted chemotherapy regimen was proposed which consisted of R-mini-CHOP every 21 days, with a reduction of 10% in the doses of doxorubicin and cyclophosphamide. During the treatment, the patient went through regular dialysis sessions, 3 times per week, with an extra session performed 12 h after each chemotherapy administration. The patient experienced no adverse events or grade 3/4 toxicities. After 6 cycles of R-mini-CHOP, the patient achieved unconfirmed complete remission, and consolidation radiotherapy was performed. At the last follow-up, he was still in unconfirmed complete remission, with a progression-free survival of 11.3 months. Conclusions: R-mini-CHOP represented a reasonable treatment option for this patient with renal failure. The oncogeriatric approach led to a successful management of this frail patient, highlighting that an adapted plan of care is a key issue to improve the outcomes of elderly cancer patients.
To estimate the prevalence of abnormal glomerular filtration rate in elderly patients with solid tumors.
A retrospective study with patients aged >65 years diagnosed with solid tumors between January ...2007 and December 2011 in a cancer center. The following data were collected: sex, age, serum creatinine at the time of diagnosis and type of tumor. Renal function was calculated using abbreviated Modification of Diet in Renal Disease (MDRD) formulae and then staged in accordance with the clinical practice guidelines published by the Working Group of the National Kidney Foundation.
A total of 666 patients were included and 60% were male. The median age was 74.2 years (range: 65 to 99 years). The most prevalent diagnosis in the study population were colorectal (24%), prostate (20%), breast (16%) and lung cancer (16%). The prevalence of elevated serum creatinine (>1.0mg/dL) was 30%. However, when patients were assessed using abbreviated MDRD formulae, 66% had abnormal renal function, stratified as follows: 45% with stage 2, 18% with stage 3, 3% with stage 4 and 0.3% with stage 5.
To the best of our knowledge, this was the first study to estimate the frequency of renal insufficiency in elderly cancer patients in Brazil. The prevalence of abnormal renal function among our cohort was high. As suspected, the absolute creatinine level does underestimate renal function impairment and should not be used as predictor of chemotherapy metabolism, excretion and consequent toxicity.
To evaluate the epidemiological profile and overall survival of a large population of elderly individuals diagnosed with solid tumors in a tertiary hospital.
This retrospective study included ...patients aged >65 years, diagnosed with solid tumors between January 2007 and December 2011, at Hospital Israelita Albert Einstein, São Paulo, Brazil. The medical records were reviewed to obtain information about clinical variables and overall survival.
A total of 806 patients were identified, and 58.4% were male. Mean age was 74 years (65 to 99 years). The most common types were prostate (22%), colorectal (21%), breast (19%), and lung cancer (13%), followed by bladder (8%), pancreas (6%), and other types (11%). The majority of patients were diagnosed at early stage disease. After a median follow-up of 27 months (15 to 45 months), 29% of the patients (234/806) died, predominantly in the group older than 70 years. For the entire cohort, the median 2-year survival rate was 71%. Median overall survival was not reached within the study period. In a multivariate analysis, age (HR: 1.35; 95%CI: 1.25-1.45; p<0.001) and disease stage (HR: 1.93; 95%CI: 1.75-2.14; p<0.001) were independent negative predictors of poor survival.
The most prevalent tumors were prostate, colorectal, breast, and lung cancer, with the larger proportion diagnosed at initial stages, reflecting the great number of patients alive at last follow-up.

Treating elderly cancer patients is a challenge for oncologists, especially considering the several therapeutic modalities in glioblastoma. Extensive tumor resection offers the best chance of local ...control. Adequate radiotherapy should always be given to elderly patients if they have undergone gross total resection and have maintained a good performance status. Rather than being ruled out, chemotherapy should be considered, and temozolomide is the chosen drug. A comprehensive geriatric assessment is a valuable tool to help guiding treatment decisions in elderly patients with glioblastoma.
