Comparative Effectiveness of Chemotherapy Alone Versus Radiotherapy-Based Regimens in Locally Advanced Pancreatic Cancer: A Real-World Multicenter Analysis (PAULA-1). Curr Oncol 2023; 30:5690-5703. [PMID: 37366910 DOI: 10.3390/curroncol30060427] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Revised: 05/30/2023] [Accepted: 06/04/2023] [Indexed: 06/28/2023] Open
Abstract
Different options for locally advanced pancreatic cancer (LAPC) are available based on international guidelines: chemotherapy (CHT), chemoradiation (CRT), and stereotactic body radiotherapy (SBRT). However, the role of radiotherapy is debated in LAPC. We retrospectively compared CHT, CRT, and SBRT ± CHT in a real-world setting in terms of overall survival (OS), local control (LC), and distant metastasis-free survival (DMFS). LAPC patients from a multicentric retrospective database were included (2005-2018). Survival curves were calculated using the Kaplan-Meier method. Multivariable Cox analysis was performed to identify predictors of LC, OS, and DMFS. Of the 419 patients included, 71.1% were treated with CRT, 15.5% with CHT, and 13.4% with SBRT. Multivariable analysis showed higher LC rates for CRT (HR: 0.56, 95%CI 0.34-0.92, p = 0.022) or SBRT (HR: 0.27, 95%CI 0.13-0.54, p < 0.001), compared to CHT. CRT (HR: 0.44, 95%CI 0.28-0.70, p < 0.001) and SBRT (HR: 0.40, 95%CI 0.22-0.74, p = 0.003) were predictors of prolonged OS with respect to CHT. No significant differences were recorded in terms of DMFS. In selected patients, the addition of radiotherapy to CHT is still an option to be considered. In patients referred for radiotherapy, CRT can be replaced by SBRT considering its duration, higher LC rate, and OS rate, which are at least comparable to that of CRT.

COVID-19 Vaccinations: Summary Guidance for Cancer Patients in 28 Languages: Breaking Barriers to Cancer Patient Information. Rev Recent Clin Trials 2022; 17:11-14. [PMID: 34967300 PMCID: PMC9241076 DOI: 10.2174/1574887116666211028145848] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2021] [Revised: 07/16/2021] [Accepted: 08/26/2021] [Indexed: 12/14/2022]
Abstract
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.

Abstract
Conventionally fractionated chemoradiation (CRT) or chemotherapy (CHT) are considered as standard options in locally advanced pancreatic cancer (LAPC) while stereotactic body radiotherapy (SBRT) is an emerging treatment in this setting. The aim of this study was to compare two cohorts of LAPC patients treated with SBRT ± CHT vs CRT ± CHT in terms of local control (LC), distant metastases-free survival (DMFS), progression-free survival (PFS), overall survival (OS), and toxicity. Eighty patients were included. Patients in the two cohorts were matched according to: age ≤/>65 years, tumor diameter (two cut-offs: </≥3.0 and </≥3.9 cm), clinical tumor stage and clinical nodal stage, neoadjuvant CHT, and adjuvant CHT. Median prescribed total dose was 30.0 Gy (range: 18.0-37.5) and 54.0 Gy (18.0-63.0) in SBRT and CRT cohorts, respectively. Toxicity was evaluated by CTCAE v4.0 scale. Survival curves were calculated by Kaplan-Meier method. For hypothesis testing an equivalence and a non-inferiority test was calculated. No statistically significant differences in terms of acute and late toxicity, DMFS, PFS, and OS were recorded among the two cohorts. Median, 1-, and 2-year LC was: 16.0 months, 53.1%, and 40.5% in the CRT cohort and 22.0 months, 80.4%, and 49.8% in the SBRT cohort, respectively (P: .017). A statistically non-inferiority significance was recorded in terms of OS between CRT and SBRT (P = .031). Patients treated with SBRT showed higher LC rate and similar OS compared to CRT. Therefore, the design of confirmatory randomized studies comparing SBRT and CRT seems justified.

Abstract
PURPOSE Glioblastoma (GBM) is the most aggressive primary brain tumor. Vascular endothelial growth factor (VEGF) gene polymorphisms and overexpression are involved in high-grade malignant gliomas. The aim of this study was to assess the distribution of +405C>G VEGF gene polymorphism in patients diagnosed by glioblastoma and to test its association with the overall survival (OS). METHODS Patients diagnosed for glioblastoma were randomly selected, and follow-up was conducted for a minimum of 36 months. Tissue paraffin embedded GBM samples were subjected for the VEGF polymorphism detection. The associations of the observed genotypes and clinical data were evaluated. RESULTS The most frequent single nucleotide polymorphism (SNP) variant was G (72.58%). The GG genotype was proved to have statistically significant longer OS and patient status (alive/dead) compared to CC and CG genotypes (p=0.022 and 0.005, respectively). CONCLUSION Our results indicate that +405C>G VEGF gene polymorphism may be used as prognostic genetic marker of OS in GBM patients.

Abstract
PURPOSE Temozolomide (TEM), an oral alkylating agent, has shown promising activity in the last 10 years in the treatment of glioblastoma multiforme (GBM). Our goal was to show the benefit of concomitant therapy involving 3D conformal radiotherapy and temozolomide in clinical practice. METHODS This was a retrospective/prospective study and included a total of 113 patients with GBM diagnosis. Forty- seven patients received postoperative radiotherapy and 66 received concomitant temozolomide plus 3D conformal radiotherapy. RESULTS The mean overall survival of patients who received postoperative radiotherapy alone was 9.93±6.475 months, compared to statistically longer overall survival in the group of patients who received radiotherapy plus temozolomide (13.89±8.049 months) (p=0.006). The latter group was divided into two subgroups, one consisting of patients who received 6 complete cycles of temozolomide, and a second with patients who received incomplete treatment. Statistically significant longer overall survival was registered in the first subgroup compared to the second (p=0.006). CONCLUSION The concomitant usage of temozolomide and radiotherapy was beneficial, and statistically significant difference among groups and subgroups was observed regarding overall survival.

Abstract
The determination of genetic background in metabolic syndrome (MetS) represents one of the necessary steps to prevent the disorder, thus reducing the cost of medical treatments and helping to design targeted therapy. The study explores the association between individual alleles of the LRP1 gene and the diagnosis of MetS to find correlation between the low-density lipoprotein receptor-related (LRP1) gene polymorphism and each individual anthropometric and biochemical parameter. The study included 93 males and females, aged from 19 to 65, divided into two groups. The genotype of each person was determined from the restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR) profile. Results indicated the association of the T allele form of exon 3 LRP1 gene with development and progression of MetS that further pointed out its negative impact on tested anthropometric and biochemical parameters. The presence of the T allele in patients multiplies the chance of occurrence of deviations from the reference values of body mass index (BMI), (4.24-fold) and low-density lipoprotein (LDL) (20.26-fold) compared to C allele carriers. The results showed that T allele presence multiplies the chance (4.76 fold) for the occurrence of MetS in comparison to C allele carriers. Correlation found that the T allele of the LRP1 gene with MetS determinants is not negligible, therefore, the T allele may be considered as a risk factor for MetS development.

Abstract
PURPOSE Melanoma represents the most severe form of skin cancer. Detection of specific tumor markers is an important step in disease diagnosis and treatment, contributing to personalized therapy. The purpose of this study was to evaluate the potential of MIA, S-100 and LDH as biomarkers for the estimation of overall survival and disease-free survival rate in patients with stage IIa, IIb vs stage IIc melanoma. METHODS Selected biomarkers MIA, S-100 and LDH were prospectively evaluated in 80 patients with melanoma. Patients were divided in two groups according to tumor thickness. The first group (group A) consisted of patients with primary tumor thickness between 2.0 - 4.0 mm (N=40), i.e. IIa and IIb stage of disease (16 males; 40%, and 24 females; 60%). The second group (group B) consisted of 40 patients with primary tumor thickness over 4.0 mm, i.e. IIc stage, which is considered as high risk group (26 males; 65%, and 14 females 35%). Statistical analyses were performed to estimate overall survival and disease-free survival in both patient groups. RESULTS In group A a significant difference in overall survival was found among MIA1, MIA2 and MIA3 scores, while the other 2 markers didn't show significant differences. In group B statistically significant differences in overall survival were found regarding all three biomarkers. Statistically significant differences in disease-free survival were found for MIA1 score compared to MIA2 and MIA3 scores. Also, very significant difference was detected in patients with S-100 below 0.106 and above 0.106. The same was confirmed for normal and increased LDH level in group B for disease-free survival. CONCLUSION MIA score, S100 protein and LDH in the IIC group B patients might be useful in the prediction of overall survival and disease free survival.

Abstract
Background/Aim. Development of imaging techniques, computed tomography (CT),
magnetic resonance imaging (MRI), and positron emission tomography (PET),
made great impact on radiotherapy treatment planning by improving the
localization of target volumes. Improved localization allows better local
control of tumor volumes, but also minimizes geographical misses. Mutual
information is obtained by registration and fusion of images achieved
manually or automatically. The aim of this study was to validate the CT-MRI
image fusion method and compare delineation obtained by CT versus CT-MRI
image fusion. Methods. The image fusion software (XIO CMS 4.50.0) was applied
to delineate 16 patients. The patients were scanned on CT and MRI in the
treatment position within an immobilization device before the initial
treatment. The gross tumor volume (GTV) and clinical target volume (CTV) were
delineated on CT alone and on CT+MRI images consecutively and image fusion
was obtained. Results. Image fusion showed that CTV delineated on a CT image
study set is mainly inadequate for treatment planning, in comparison with CTV
delineated on CT-MRI fused image study set. Fusion of different modalities
enables the most accurate target volume delineation. Conclusion. This study
shows that registration and image fusion allows precise target localization
in terms of GTV and CTV and local disease control.

Abstract
BACKGROUND/AIM [corrected] Alternative medicine is a set of therapeutic procedures which are no part of official practice. At present, the use of alternative medicine among cancer patients is significant and the purpose of this study was to get more information on the methods and products of alternative medicine. Thus, the aim of the study was to determine the frequency of the use of alternative medicine among gastrointestinal cancer patients. METHODS The research was conducted using an anonymous questionnaire in writing. We included 205 patients with the diagnosis of gastrointestinal malignancy in the study but the questionnaire was fulfilled by 193 patients and the presented data were based on their answers. The questions were about the sociodemographic characteristics of the patients, the reasons for their use of alternative medicine, and their information sources about alternative medicine. We divided existing alternative therapies into 6 categories: herbal therapy, special diets, psychotherapy, body-mind therapy, spiritual therapy, and other supplements. RESULTS A total of 48 (24.9%) patients did not use any type of alternative therapy; 145 (75.1%) patients used at least one product and 124 (64.25%) patients used herbal preparations (beetroot juice was consumed by 110 [56.99%] patients); 136 (70.5%) patients were informed about alternative therapies by other patients; 145 (75.1%) used alternative medicine to increase the chances for cure; 88 (45.6%) of interviewed patients would like to participate in future research in this field. CONCLUSION The use of alternative medicine is evidently significant among cancer patients. Further research should be conducted in order to find out interactions of these products with other drugs and potential advantages and disadvantages of this form of treatment.

Abstract
INTRODUCTION Breast cancer is one of the most common malignancies in women and the main leading cause of cancer death. The most frequent sites of metastases from breast cancer are bones, lungs, the central nervous system, the liver and soft tissue. Colonic metastases from breast cancer are rare. CASE REPORT We presented a 70-year-old woman with bulky obstructing lesion of sigmoid colon. A physician in charge on our department examined the patient and past history of breast cancer was found up. Surgery was performed with removal of sigmoid colon and three of six lymph nodes were positive. Pathological examination, including immunohistochemical stains, confirmed the diagnosis of metastatic breast cancer to sigmoid colon. The multidisciplinary oncology team suggested postoperative chemotherapy. The patient received four cycles of chemotherapy with paclitaxel followed by anastrozole. On the first control visit no disease activity was detected. CONCLUSION In patients with the past history of breast cancer the symptoms of hematochezia or anemia may indicate colonic metastases.

Abstract
Cystic echinococcosis (CE) is a public health problem in countries having such endemic areas. Epidemiological studies of CE, especially pediatric, are rare. The aim of this study was to evaluate epidemiological and clinical characteristics of CE in children in Serbia. Data were obtained retrospectively from the case records of patients under the age of 18 years admitted for surgical treatment of CE at two large pediatric medical institutions in the period 1990-2006. Patients' age, number of cysts and their anatomic location were evaluated in relation to differences by patients' gender and socio-geographic status (urban or rural origin). The study included 149 children with 272 hydatid cysts. The mean age of patients was 10.1+/-3.8 years. There were no significant differences in the number of patients in relation to gender and urban:rural origin. There were no significant differences in patients' age at the time of surgery or the number of cysts per patient when patients' gender or socio-geographic status was evaluated. The anatomic location of cysts was as follows: liver (N=165; 60.7%), lungs (N=82; 30.1%), and other locations (N=25; 9.2%). Multiple cysts, and combined liver/lung involvement were identified in 34.2% (N=51), and 6.0% (N=9) of patients, respectively. Hepatic cysts were significantly more common in girls than in boys. There were no significant differences in anatomic location of cysts between socio-geographic groups. The large number of infected children during a long period of investigation indicates an active transmission of disease and a lack of program for control and prevention of CE in Serbia.
