RESUMO

INTRODUCTION/BACKGROUND: Adjuvant capecitabine monotherapy is an option for colon and upper rectum adenocarcinoma patients, providing they have stage II disease with an intermediate risk of recurrence, or stage III but they are above 70's or they have comorbidities. We wanted to examine whether the number of chemotherapy cycles and the relative dose intensity (RDI) of capecitabine monotherapy in the adjuvant setting are affecting disease recurrence. PATIENTS AND METHODS: We included patients with completely resected stage II and III colon and upper rectum cancer who received adjuvant capecitabine monotherapy, from 2003 until May 2020. Patients with early relapse, i.e. during chemotherapy or within 6 months after the completion of adjuvant chemotherapy, and those with rectal cancer who received radiotherapy were excluded. Patients were divided into 3 groups based on the number of chemotherapy cycles received and the RDI. Group A included patients with ≤4 cycles of chemotherapy, group B patients with >4 cycles of chemotherapy and RDI ≤80%, and group C patients with >4 cycles of chemotherapy and RDI >80%. Study's endpoint, was recurrence free survival (RFS). RESULTS: Two hundred twenty six patients with stage II and III disease (164 and 62 respectively) were included. Sixteen, 166 and 44 were included in groups A, B and C respectively. After a median follow-up of 41 months, 21 patients (9,3%) had relapsed. Patients belonging to group C were found to have a trend for lower relapse rate compared to patients belonging to group A or group B. CONCLUSION: Number of adjuvant capecitabine cycles and RDI might play a role in RFS in patients with stage II and III colon and upper rectum adenocarcinoma.

RESUMO

BACKGROUND: Management of Ras wild-type colorectal cancer (CRC) patients upon disease progression after the successful use of targeted treatment with anti-EGFR monoclonal antibodies and backbone chemotherapy remains a clinical challenge. SUMMARY: Development of treatment resistance with prevalence of preexisting RAS mutated clones, RAS mutation conversion, truncation of extracellular receptor domains as well as HER2 and MET amplification are molecular events that can be difficult to follow without the use of sophisticated laboratory techniques. The clinical hurdle of re-biopsy and tumor heterogeneity can be overcome by the implementation of next-generation sequencing (NGS) to analyze circulating tumor DNA (ctDNA) and identify druggable mutations or recovery of RAS-wildness. In this opinion paper, we summarize with critical thinking the clinical approach to be followed after the failure of first-line treatment in Ras wild-type CRC tumors with the use of NGS. Rechallenge with anti-EGFR inhibitors, in case of persistent or recovery of RAS-wildness, and targeted approach of specific mutations (BRAF inhibitors), amplifications (anti-Her2 treatment), or fusion proteins (NTRK inhibitors) can by guided by the use of NGS. The use of NGS platforms for serial analysis of ctDNA is an important step to better understand the molecular landscape of metastatic CRC and guide clinical decisions. KEY MESSAGES: NGS should be considered a mainstay in clinical practice for the management of CRC patients and health authorities should consider reimbursing its use in the appropriate clinical settings.

RESUMO

BACKGROUND: Covid-19 vaccination has started in the majority of the countries at the global level. Cancer patients are at high risk for infection, serious illness, and death from COVID-19 and need vaccination guidance and support. Guidance availability in the English language only is a major limit for recommendations' delivery and their application in the world's population and generates information inequalities across the different populations. METHODS: Most of the available COVID-19 vaccination guidance for cancer patients was screened and scrutinized by the European Cancer Patients Coalition (ECPC) and an international oncology panel of 52 physicians from 33 countries. RESULTS: A summary guidance was developed and provided in 28 languages in order to reach more than 70 percent of the global population. CONCLUSION: Language barrier and e-guidance availability in the native language are the most important barriers when communicating with patients. E-guidance availability in various native languages should be considered a major priority by international medical and health organizations that are communicating with patients at the global level.

RESUMO

Immuno-oncology (IO) with immune checkpoint inhibitors (ICIs) is the new landmark in cancer treatment. However, due to its economical-related burden and the possibility of tumor pseudoprogression with late response patterns, it is imperative to find new ways for early discrimination of patients with IO-sensitive versus IO-resistant disease. ICI-mediated antitumor responses depend on tumor immune infiltration by T-cells capable of recognizing and killing tumor cells. Nevertheless, patients may experience different responses to immunotherapy according to their tumor microenvironment and inflammatory infiltration. T-cell infiltrated tumors are referred to as 'hot' and are potential candidates for a good response to ICIs, whereas 'cold' are those tumors lacking T-cell infiltration and exhibit a narrow likelihood of response to IO therapy. Gallium-67 (67Ga) scintigraphy may hold potential for separating 'hot' from 'cold' tumors, thus providing an imaging tool to distinguish 'hot' ICI-induced pseudoprogression from real early 'cold' progression. Even so, various tumors (lymphomas, lung cancer, breast cancer, hepatoma, malignant melanoma) exhibit an inherent affinity for 67Ga that is independent of the ICI-induced immune infiltration, and this raises issues about false positivity. For that reason, future investigational studies to evaluate the prospective role of this radiotracer in the early prediction of ICI response should be confined to tumors with an inherently low 67Ga affinity (thyroid carcinoma, gastrointestinal and genitourinary tract tumors). We describe our experience with a patient with recurrent metastatic lung adenocarcinoma under ICI therapy that was submitted to 67Ga scanning for a fever of unknown origin and we discuss the aforementioned topics, alongside current imaging trends and future perspectives in the field.

RESUMO

Testicular metastases from ureteral carcinoma are rare and they are generally mimic orchiepididymitis. For this reason, these are associated to misleading diagnoses and cancer treatment delay. We believe that both timing and knowledge of genital blood and lymph reverse flow routes may represent two important parameters for avoiding misleading diagnoses and speed proper anticancer treatment. We describe a case and discuss pathophysiological data and relevant literature.

RESUMO

As the incidence of malignancies in young adults is increasing, fertility preservation in cancer survivors arises as a major concern. Especially among female cancer patients, pregnancy rates are estimated to be 40% lower compared to women of the same age. Nowadays oncologists are to be preoccupied not only with their patients' successful treatment, but also with the maintenance of the potential of the latter to conceive and obtain children. Chemotherapy associated ovarian failure (COF), refers to disruption of ovarian function both as an endocrine gland and as a reproductive organ, due to previous exposure to chemotherapy agents. Although the underlying mechanism is not fully understood, it is supposed that chemotherapy agents may induce either DNA damage of premature ovarian follicle or early activation and apoptosis of them, resulting into early exhaustion of available follicle deposit. Various chemotherapy agents have been associated with COF with the highest incidence being reported for patients undergoing combination regimens. Although a variety of alternatives in order to maintain ovarian function and fertility in female cancer survivors are available, adequately established practices to do so are lacking. Thus, it is of major importance to investigate further and collect sufficient evidence, aiming to guide patients and physicians in everyday clinical practice.

RESUMO

Storey duplex houses are today one of the fastest growing housing market. The key of success is that this kind of house architecture presents esthetic and practical advantages in the average family daily life, but its narrow indoor staircase connecting the ground floor (floor of family activities) to the "bedroom floor" may constitute a potential detriment for the care and quality of life of patients with advanced cancer. Due to cancer cachexia, cancer pain and asthenia, the patients' incapacity to use narrow stairs will become soon an impassable barrier. Alone at the bedroom floor in solitude, depression, months /years exclusion from family daily life, and incapacity to reach medical care services harm not only their quality of life but also the same survival outcome. Creation of a provisional functional room at the ground floor (by low cost easily-removable aluminum door and aluminum panels) enambles patients to return to family life, improve their mood, quality of life and likely survival. Concluding, in the era of storey houses housing markets, homify and interior architecture design interventions may represent a new cost-effective horizon in cancer care.

RESUMO

Angiogenesis has long been considered to facilitate and sustain cancer growth, making the introduction of anti-angiogenic agents that disrupt the vascular endothelial growth factor/receptor (VEGF/VEGFR) pathway an important milestone at the beginning of the 21st century. Originally research on VEGF signaling focused on its survival and mitogenic effects towards endothelial cells, with moderate so far success of anti-angiogenic therapy. However, VEGF can have multiple effects on additional cell types including immune and tumor cells, by directly influencing and promoting tumor cell survival, proliferation and invasion and contributing to an immunosuppressive microenvironment. In this review, we summarize the effects of the VEGF/VEGFR pathway on non-endothelial cells and the resulting implications of anti-angiogenic agents that include direct inhibition of tumor cell growth and immunostimulatory functions. Finally, we present how previously unappreciated studies on VEGF biology, that have demonstrated immunomodulatory properties and tumor regression by disrupting the VEGF/VEGFR pathway, now provide the scientific basis for new combinational treatments of immunotherapy with anti-angiogenic agents.

RESUMO

To protect cancer patients from COVID-19 exposure, prioritization strategies are being implemented at global level. Measures include use of tele-health services, deferring elective surgeries, delaying non life-saving therapies, interrupting maintenance and supportive care regimens and suspending screening and regular follow-up visits. Nonetheless, the risk of infection may not always outweigh oncology treatment benefit. Lives of most oncology patients depend on their ability to receive medical, surgical and radiotherapy care. Postponing screening, follow-up and radical surgeries increase patients' risk of developing metastatic disease. A viral pandemic lasts long time and exhibits seasonal and geographical variations. Though vaccines will be available only in the 2021, a global, aggressive, all-embracing and protracted slowdown of oncologic activities will severely jeopardize patients' outcomes. A present international oncologists' panel, ECPC and FAVO, strongly suggest that Hospital measures in a specific geographical area/Nation should be in line with the local epidemic, and restrictions adopted should be adapted and stratified over time.

RESUMO

With the advent of immunotherapy and with the expanding spectrum of malignancies treated with immunomodulatory agents, a new kind of adverse events has come under the spotlight. Clinicians have to be aware of immune-related adverse events and their clinical manifestations. Immunotherapy has been strongly associated with endocrinopathies, gastrointestinal, pulmonary, cutaneous, and renal toxicities but the incidence of rheumatologic adverse events is lower compared to the aforementioned systems. Dermatomyositis is an autoimmune myopathy which has been correlated to underlying evident or occult malignancies. Apart from its characteristic symptoms and signs, the presence of specific antibodies such as anti-transcriptional intermediary factor 1γ (anti-TIF 1γ) usually supports the diagnosis of paraneoplastic nature of the disease. However, a solid distinction between paraneoplastic syndrome and immune-related adverse event is still missing and remains to be elucidated. We here present a case of dermatomyositis in a male patient who underwent four cycles of combined ipilimumab and nivolumab immunotherapy. This is, to our knowledge, the first case of dermatomyositis following combined immune checkpoint inhibition therapy.

RESUMO

Acquired hemophilia is a rare autoimmune bleeding disorder related to the production of autoantibodies that inhibit clotting factor VIII or IX. The underlying cause can be autoimmune disease, malignancy, pregnancy, or medications, but it is most commonly idiopathic. Here we present the case of an 81-year-old patient with locoregionally relapsed periampullary carcinoma who presented with soft tissue hematoma and an abnormally elevated activated partial thromboplastin time (aPTT) in the presence of a normal prothrombin time. A diagnosis of acquired hemophilia was established. The patient was managed with immunosuppressive prednisone and cyclophosphamide plus immunoglobulin G. He also received a cycle of chemotherapy with gemcitabine and oxaliplatin, because the underlying malignancy was the cause of the bleeding disorder. Care was complicated by neutropenia and nosocomial fever, but the patient eventually showed signs of clinical stability, while the aPTT decreased 2-fold. The patient was successfully discharged from the hospital and continued treatment in outpatient care.

RESUMO

BACKGROUND: Anthracycline-induced cardiomyopathy is a serious side effect that ranges from mild left ventricular systolic impairment to congestive heart failure and cardiogenic shock. Currently, there is no evidence indicating the effective use of levosimendan in these cases. OBJECTIVE: We aim to present a case of life-threatening doxorubicin-induced cardiomyopathy that was successfully managed with levosimendan. CASE: A 48-year-old female with formerly normal heart function, who had been treated with doxorubicin-based regimens for dedifferentiated chondrosarcoma, presented with cardiomyopathy with low left ventricular ejection fraction eight months after the last infusion. As treatment with ramipril, carvedilol, and furosemide followed by dopamine and noradrenaline was not sufficient, levosimendan was administered. Left ventricular ejection fraction increased from 15% to 45% and her clinical condition improved. DISCUSSION: Although anthracycline-induced cardiomyopathy may have a poor prognosis, levosimendan was shown to be effective in this patient. Therefore, levosimendan may represent a possible therapeutic option in such cases.
