Background The aim of the study is to analyze potential prognostic factors and to evaluate therapy strategies regarding clinical outcome in patients with eccrine porocarcinoma (EPC) of the head and neck. Methods One hundred and sixteen EPC cases from ninety studies and four authors' EPC cases were included in the meta‐analysis. Results At an average follow up of 20.48 months, the 3‐year overall survival and regional recurrence rate were 70.3% and 19.0%, respectively. Patients without surgical treatment had a significantly worse 3‐year overall survival. Mohs microscopic surgery led to significantly less occurrence of regional recurrences compared to wide excision. An ulcerating lesion, high mitotic activity, and lymphovascular invasion were significant prognostic factors. Conclusion Surgical resection is the cornerstone in the therapy of EPC and represents the therapeutic modality that offers the best chance of disease‐free survival. Due to the high probability of recurrence, close follow‐ups are strongly recommended.
Background The purpose of this study was to analyze and compare ipsilateral and bilateral adjuvant radiotherapy in patients with cancer of unknown primary (CUP) of the head and neck. Methods Overall survival, recurrence‐free survival, and radiation‐induced side effects were assessed in 76 patients with CUP who underwent ipsilateral (n = 29) or bilateral (n = 47) radiotherapy. Results At a median follow‐up of 41 months, the 5‐year overall survival and recurrence‐free rate were 67.9% and 71.5%, respectively. No statistically significant difference between ipsilateral and bilateral radiotherapy could be found regarding 5‐year overall survival, recurrence‐free survival, occurrence of a primary tumor, and distant metastasis. The analysis of radiation‐induced acute side effects showed a significant benefit of ipsilateral radiotherapy. Conclusion As the main parameters of the study regarding the outcome and radiation‐induced side effects showed no advantages of bilateral radiotherapy, the strategy of ipsilateral radiotherapy can be recommended for the adjuvant treatment of CUP patients.
Background. The purpose of this study was to analyze the value of different diagnostic methods in detecting the primary site and the impact of primary tumors on the clinical outcome of carcinoma of unknown primary (CUP). Methods. In this multicenter, retrospective study, 124 patients with true CUP (n = 94) and CUP turned to primary carcinoma (n = 30) were included. Patients with evidence of primary site during the clinical examination were excluded a priori. The diagnostic procedure was comprised of imaging and invasive methods (fine-needle-aspiration, tonsillectomy and panendoscopy). All patients were treated with curative intent. Results. Despite extensive diagnostic workup, the primary site remained unknown in 75.8%. Invasive diagnostic methods showed higher primary detection rates than imaging modalities (15.1% vs. 7.8%). Tonsillectomy and panendoscopy revealed the primary tumor in 14.9% and 15.2% of patients, whereas the detection rates of CT, MRI and FDG-PET-CT were 10.1%, 4.8% and 6.5%, respectively. The occurrence of primary tumors led to a significantly deteriorating 5-year overall survival (p = 0.002) and emerged as survival prognosticator (HR = 2.764, p = 0.003). Conclusion. Clinical examination in combination with tonsillectomy and panendoscopy was superior to imaging alone in detecting the primary tumor. When the CUP of patients turned to a primary tumor, clinical outcome was significantly worse than in CUP patients.
Vaccination is the primary public health strategy to cope with the COVID-19 pandemic. Although solid tumor and hematologic patients are at higher risk of serious COVID-19-related complications, data on immune responses to COVID-19 vaccines in this patient cohort are particularly scarce. The present study, therefore, aimed at the standardized determination of anti-SARS-CoV-2 spike protein antibody titers among non-vaccinated versus vaccinated solid tumor and hematologic patients who are under clinical observation or under treatment at the University Hospital Krems. Standardized anti-SARS-CoV-2 S antibody titers of a total of 441 patients were retrospectively analyzed. Our results show that antibody titers against the SARS-CoV-2 spike protein are significantly higher in solid tumor versus hematologic patients. While SARS-CoV-2 antibody titers were equal among sexes, an age-dependent decrease was observed. Of note, our studies additionally show that complete vaccination represents a valuable predictor for high anti-SARS-CoV-2 antibody responses in solid tumor and hematologic patients. In summary, to date, this is one of the largest studies to comprehensively evaluate the impact of various COVID-19 vaccines on anti-SARS-CoV-2 S antibody production in solid tumor and hematologic patients. Our findings aim to support future vaccination strategies in these highly vulnerable patients, including vaccination booster programs and alternative protective approaches.
Opinion StatementSystemic anticancer therapy (SACT) includes different treatment modalities that can be effective in treating cancer. However, in the case of disease progression, cancers might become incurable and SACT might reach its limits. In the case of incurable cancers, SACT is often given in a palliative setting, with the goal of improving the patients’ quality of life (QOL) and their survival. In contrast, especially for patients who approach end of life (EOL), such treatments might do more harm than good. Patients receiving EOL anticancer treatments often experience belated palliative care referrals. The use of systemic chemotherapy in patients with advanced cancer and poor prognosis approaching the EOL has been associated with significant toxicity and worse QOL compared to best supportive care. Therefore, the American Society of Clinical Oncology (ASCO) has discouraged this practice, and it is considered a metric of low-value care by Choosing Wisely (Schnipper et al. in J Clin Oncol 4;30(14):1715-24). Recommendations of the European Society for Medical Oncology (ESMO) suggest that especially chemotherapy and immunotherapy should be avoided in the last few weeks of the patients’ lives. In this narrative review, we screened the current literature for the impact of SACT and factors predicting the use of SACT near the EOL with discussion on this topic.
Timely integration of specialized palliative care (SPC) has been shown to improve cancer patients’ quality of life (QoL) and reduced the use of medical services. To evaluate the level of integration of SPC services for patients with advanced small-cell lung cancer (SCLC), we retrospectively analyzed medical records of patients from 2019 to 2021. Regarding the timing of referral to SPC services, we defined four cutoffs for early referral according to the current literature: (a) SPC provided ≤ 60 days after diagnosis; (b) SPC provided ≥ 60 days before death; (c) SPC provided ≥ 30 days before death; and (d) SPC provided ≥ 130 days before death. One hundred and forty-three patients (94.1%) were found to have locally advanced (stage III) or metastatic (stage IV) disease. Sixty-eight were not referred to SPC services (47.6%), whereas 75 patients received SPC (52.4%). We found a significantly higher number of referrals to SPC services for patients with higher ECOG (Eastern Cooperative Oncology Group) (i.e., ECOG ≥ 2) (p = 0.010) and patients with stage IV disease (p ≤ 0.001). The median overall survival (OS) for SCLC stage III/IV patients (n = 143) who did not receive SPC treatment was 17 months (95% CI 8.5–25.5), while those who did receive SPC treatment had a median OS of 8 months (95% CI 6.2–9.8) (p = 0.014). However, when we evaluated patients receiving SPC treatment in a timely manner before death as suggested by the different cutoffs indicated in the literature, they lived significantly longer when referred at a minimum of ≥60 or ≥130 days before death. Based on our findings, we suggest that patients with advanced SCLC should participate in a consultation with a SPC team in a timely manner to ensure a benefit of SPC for this patient group.
While participating in social insurance is a legitimate right of employees, it is also an important cost in business’s operation. During an economic crisis, this cost becomes much more costly for enterprises. According to a survey report prepared by the Board of Research on Private Economic Development (also known as Board IV, which belongs to the Prime Minister's Advisory Council for Administrative Procedure Reform) on the impact of the Covid-19 epidemic on production and business activities of enterprises conducted in 2020, the immediate supporting solution that companies proposed the most and expect the Government to prioritize and focus on is: Implementing particular policies on taxation and also social insurance exemption and reduction during the epidemic period for businesses heavily affected by Covid-19. However, according to current legal regulations, the mechanism to amend the rate of social insurance premiums still has many problems to be solved. In this article, the author focuses on studying the impact of Covid-19 on businesses in Vietnam and legal barriers related to social insurance exemptions and reductions, and then proposes solutions to the problems posed.
