This study was aimed to analyze the most common diagnostic and therapeutic errors in orthopaedic oncological diseases. Bone tumors usually do not have characteristic symptoms, especially in the early stages of disease development. Therefore, they can often mimic benign tumors and non-tumor diseases. Careful history taking, detailed clinical and X-ray examinations in a timely manner are essential diagnostic tools for patients with bone sarcomas. Moreover, a correct analysis of clinical and radiological findings with regard to the dynamic relationship between them can help make more accurate diagnosis at the first doctor’s visit. Subsequent X-ray examinations performed in oncological centers using special methods such as spiral CТ, MRI, PET/CT with mandatory morphological verification of the diagnosis enable us to make a more precise diagnosis and to provide an objective assessment of pathological processes. The most common diagnostic and therapeutic errors that occur in orthopaedic oncological diseases were analyzed. In 35 % of cases, diagnostic or tactical errors were made by general practitioners. In 15 % of cases, the errors were associated with a latent course of disease and 12 % of cases were wrongly diagnosed as a benign neoplasm.

Carcinosarcoma, leiomyosarcoma, melanoma and carcinoid as primary tumors in the ovary are extremely rare. In this paper, the authors reviewed the literature from 2010 to 2021, based on specific criteria, to analyze the treatment of these rare ovarian neoplasms. We also aimed to verify whether modern therapies have been found in recent years. For this article, 80 papers were finally selected. The vast majority of the articles were clinical case reports. Despite single mentions of new potential pharmacological treatments, surgery (radical or fertility-sparing) is definitely the mainstay of treatment. There are currently no treatment guidelines for these tumors. A review of the literature has revealed the use of various adjuvant treatments. We, therefore, believe that a more detailed understanding of the biology of these tumors is necessary in order to find new target points for treatment. We would like to emphasize the importance of creating an international database of rare ovarian tumors which would make it possible to gather data from various oncological centers and enable further research into these neoplasms.

Abstract Purpose Neuro-oncology tumor boards (NTBs) hold an established function in cancer care as multidisciplinary tumor boards. However, NTBs predominantly exist at academic and/or specialized centers. In addition to increasing centralization throughout the healthcare system, changes due to the COVID-19 pandemic have arguably resulted in advantages by conducting clinical meetings virtually. We therefore asked about the experience and acceptance of (virtualized) NTBs and their potential benefits. Methods A survey questionnaire was developed and distributed via a web-based platform. Specialized neuro-oncological centers in Germany were identified based on the number of brain tumor cases treated in the respective institution per year. Only one representative per center was invited to participate in the survey. Questions targeted the structure/organization of NTBs as well as changes due to the COVID-19 pandemic. Results A total of 65/97 institutions participated in the survey (response rate 67%). In the context of the COVID-19 pandemic, regular conventions of NTBs were maintained by the respective centers and multi-specialty participation remained high. NTBs were considered valuable by respondents in achieving the most optimal therapy for the affected patient and in maintaining/encouraging interdisciplinary debate/exchange. The settings of NTBs have been adapted during the pandemic with the increased use of virtual technology. Virtual NTBs were found to be beneficial, yet administrative support is lacking in some places. Conclusions Virtual implementation of NTBs was feasible and accepted in the centers surveyed. Therefore, successful implementation offers new avenues and may be pursued for networking between centers, thereby increasing coverage of neuro-oncology care.

The lecture presents up-to-date information on the prevalence of cancer in the world and in the Russian Federation. The main risk factors and causes of malignant tumors are considered. Particular attention is paid to the mechanisms of transformation of normal cells into tumor cells, and the role of oncogenes and anti-oncogenes in the initiation of malignant growth is shown. Based on modern information about carcinogenesis, the pathogenetic significance of the molecular mechanisms of malignant cell growth at various stages (initiation, promotion, progression) of the tumor process is shown. The mechanisms of evasion of tumors from the influence of immune and other mechanisms that restrain their emergence and development in the body are described, and it is also shown how the spread (metastasis) of malignant cells occurs. The modern tumor markers are presented, on the basis of which the earlier detection of malignant diseases is performed. Particular attention is paid to molecular diagnostic approaches to assessing the risk of occurrence and early diagnosis of malignant neoplasms. Genomic, epigenetic and interactomic tumor markers, which are used in leading domestic and foreign oncological centers, are considered. The most promising approaches to the creation of effective anticancer drugs obtained on the basis of the achievements of molecular biology and bioinformatics are highlighted.

We aimed to investigate the effectiveness of oncological treatments in metastatic CRC related to comorbidities and age. This retrospective study included 1105 patients from three oncological centers. aaCCI and CCI was available from 577 patients. An aaCCI > 3 was of the highest predictive value compared to other aaCCI-levels, CCI or age (p < 0.001 for all). Treatment (best supportive care (BSC), systemic treatment only (STO) and resection of metastases (ROM)) significantly prolonged survival in patients with aaCCI > 3 (STO: HR 0.39, CI 0.29–0.51; ROM: HR 0.16, CI 0.10–0.24) and patients older than 70 years (STO: HR 0.56, CI 0.47–0.66; ROM: HR 0.23, 0.18–0.30). Median overall survival was shorter in patients with aaCCI or age > 70 years and interaction for treatment type not significant for aaCCI, but significant for age older or younger than 70 years (STO: p = 0.01; ROM p = 0.02). BSC is more often considered as optimal care for patients with an aaCCI > 3 (37.6% vs. 12.4%; p < 0.001) or age > 70 years (35.7% vs. 11.2%; p < 0.001). Older patients or patients with comorbidities benefit from cancer-specific therapy independently of their age and comorbidities.

Cytoreductive surgery and HIPEC have become de pillars of treatment in advanced, metastatic colorectal cancer. This state of evolution of the disease was considered terminal just a few years ago.  It has been demonstrated that by combining these therapies in selected patients one can increase survival time. Once this has been obtained to some length modern studies have been focused on the quality of life, safety, and how this time interval can be increased. We have reviewed the most important prospective, randomized clinical trials regarding HIPEC and peritoneal carcinomatosis. The technique, complications, principles of action, and evolution through time of HIPEC have been addressed and covered. Special consideration had been given to the correlation between the carcinomatosis index and HIPEC. HIPEC with maximal cytoreduction can be considered a curative procedure only in strictly selected patients diagnosed with colorectal cancer and peritoneal carcinomatosis. Although it has been present in the medical field for almost 30 years, it is not wide-spread due to the high costs of implementation and the requirement of highly specialized surgical and medical teams. As technology evolves, the costs can be decreased and HIPEC should be largely available in oncological centers since the foundation of implementation is solid and the fact that clear benefits although small have been demonstrated. Taking into account all of the above, HIPEC should not be considered a standard treatment at present and should only be performed in experienced centers. The correct selection of patients is critical to the success of this procedure. Maximum cytoreduction should only be performed if the carcinomatosis index allows.

AbstractThe aim of the study was to retrospectively compare the effectiveness of the ALL IC-BFM 2002 and ALL IC-BFM 2009 protocols and the distribution of risk groups by the two protocols after minimal residual disease (MRD) measurement as well as its impact on survival. We reviewed the medical records of 3248 patients aged 1–18 years with newly diagnosed ALL who were treated in 14 hemato-oncological centers between 2002 and 2018 in Poland. The overall survival (OS) of 1872 children with ALL treated with the ALL IC 2002 protocol was 84% after 3 years, whereas the OS of 1376 children with ALL treated with the ALL IC 2009 protocol was 87% (P < 0.001). The corresponding event-free survival rates were 82% and 84% (P = 0.006). Our study shows that the ALL IC-BFM 2009 protocol improved the results of children with ALL compared to the ALL IC-BFM 2002 protocol in Poland. This analysis confirms that MRD marrow assessment on day 15 of treatment by FCM-MRD is an important predictive factor.

Synchronous cancers should be first evaluated at high-volume referral oncological centers. Multidisciplinary evaluation, as the first step of multimodal treatment strategy, is also a way to select candidates fit for surgical resections. Concurrent minimally invasive approaches are a safe and effective option that may result in long-term control of the disease. Robot-assisted surgery allows obtaining the oncological radicality with lower invasiveness for the patient, thus retaining greater surgical aggressiveness even in high-risk patients. The reports of successful synchronous robot-assisted pulmonary and urologic resections for cancer in frail elderly subjects are described here.

The aim of this cross-sectional study was to determine non-medical and organizational needs among cancer patients during diagnosis and treatment. The study included 384 cancer patients treated in five oncological centers in Poland. A questionnaire designed for the study was used. Most of the patients received psychological support from their partner/family/friends (88%), to a lesser extent from a psychologist (21%) and priests (4%). Forty-three percent of patients received social support from their partner/family/friends and only 7% of respondents received support from a social worker. Most patients stated they would like to have a professional who would help them with their non-medical problems during the diagnostic process and cancer treatment. The youth, with a higher education level who were professionally active and living in cities seemed to be more aware of their needs. Improvements to the oncological system in Poland should focus on expanding patient access to professional support of non-medical needs.

Abstract INTRODUCTION Malignant gliomas are aggressive primitive brain tumor in adults. Today, the standard of care is Temozolomide (TMZ) administered daily with radiation therapy, followed by adjuvant TMZ. TMZ treatment has been considered to have a low toxicity profile. However, during concomitant treatment some patient may develop a severe myelosuppression. This toxicity may be in some cases prolonged and lead to treatment discontinuation. METHODS We have retrospectively collected data from 5 Italian neuro-oncological centers, about glioma patients who developed severe and prolonged hematological toxicity during concomitant chemoradiotherapy with TMZ. The purpose of this study is to evaluate: percentage of patients receiving adjuvant chemotherapy after severe myelotoxicity; rate of toxicity observed during adjuvant chemotherapy. RESULTS 54 glioma patients who developed myelosuppression of grade 3 or 4 were considered. Histology was Glioblastoma in 45 patients (83%); 63% of patients were female. Myelotoxicity during concomitant phase occurred at a median of 4 weeks (range 1–8) from the start of treatment. After recovery of myelotoxicity 19 patients did not received any treatment while 35 (65%) were treated with chemotherapy (28 received standard TMZ, one TMZ with metronomic schedule, 2 lomustine and 4 other agents). Among patients treated with TMZ, 13 patients presented hematological toxicity grade 3–4 which required treatment discontinuation in 7 cases (20%). CONCLUSION the results of our study show that 80% of glioma patients presenting severe myelotoxicity during concomitant radiochemotherapy may be treated with maintenance TMZ after recovery of myelosuppression.
