Response evaluation utilized progression-free survival (PFS) categorized as responders (R; PFS &gt; 6 months) and non-responders (NR; PFS ≤ 6 months). Lesion size and density, along with maximum and median standardize uptake value (SUV) in target lesions, liver, and spleen were assessed. Tumor-to-spleen (T/S) and tumor-to-liver (T/L) ratios were calculated, including the tumor-to-spleen (T/S) ratio and tumor-to-liver (T/L) ratio (using SUVmax/SUVmax, SUVmax/SUVmean, and SUVmean/SUVmean).</p></sec> <sec><title style='display:none'>Results</title><p>PET/CT scans were acquired 19 days (interquartile range [IQR] 69 days) pre-treatment and 127 days (IQR 74 days) post-starting everolimus. The overall median PFS was 264 days (95% CI: 134–394 days). R exhibited significant decreases in Tmax/Lmax and Tmean/Lmax ratios compared to NR (p = 0.01). In univariate Cox regression, Tmean/Lmax ratio was the sole prognostic parameter associated with PFS (HR 0.5, 95% CI 0.28–0.92, p = 0.03). Percentage changes in T/L and T/S ratios were significant predictors of PFS, with the highest area under curve (AUC) for the percentage change of Tmean/Lmax (AUC = 0.73). An optimal threshold of &lt; 2.5% identified patients with longer PFS (p = 0.003). No other imaging or clinical parameters were predictive of PFS.</p></sec> <sec><title style='display:none'>Conclusions</title><p>This study highlights the potential of quantitative SSTR-PET/CT in predicting and monitoring everolimus response in NET patients.

The development of intestinal-type gastric cancer occurs through a multistep process in which normal mucosa is sequentially transformed into hyperproliferative epithelium, followed by metaplastic processes leading to carcinogenesis. Chronic infection with <italic>Helicobacter pylori</italic> is the primary etiological agent that causes chronic inflammation of the gastric mucosa, induces atrophic gastritis, and can lead to intestinal metaplasia and dysplasia. Both intestinal metaplasia and dysplasia are precancerous lesions, in which gastric cancer is more likely to occur. Atrophic gastritis often improves after eradication of <italic>Helicobacter pylori</italic>; however, the occurrence of intestinal metaplasia has been traditionally regarded as “the point of no return” in the carcinogenesis sequence. <italic>Helicobacter pylori</italic> eradication heals non-atrophic chronic gastritis, may lead to regression of atrophic gastritis, and reduces the risk of gastric cancer in patients with these conditions. In this article, we discuss the pathogenesis, epigenomics, and reversibility of intestinal metaplasia and briefly touch upon potential treatment strategy.</p> </sec> <sec><title style='display:none'>Conclusions</title> <p>Gastric intestinal metaplasia no longer appears to be an irreversible precancerous lesion.

In this narrative review we discuss potentially fatal complications of new systemic anticancer therapies and some practical considerations for their diagnosis and initial treatment.</p> </sec> <sec><title style='display:none'>Results</title> <p>Clinical presentation of toxicities of new anticancer therapies may be unpredictable and nonspecific. They can mimic other more common medical conditions such as infection or stroke. If not recognized and properly treated these toxicities can progress rapidly into life-threatening conditions. ICIs can cause immune-related inflammatory disorders of various organ systems (e.g. pneumonitis or colitis), and a cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) may develop after treatment with CAR T-cells or BiTEs. The cornerstones of management of these hyper-inflammatory disorders are supportive care and systemic immunosuppressive therapy. The latter should start as soon as symptoms are mild-moderate. Similarly, some severe toxicities of ADCs also require immunosuppressive therapy.

Immunohistochemistry was used to detect the expression of hypoxia inducible factor-1α (HIF-1α), vascular endothlial growth factor (VEGF) and vascular endothelial growth factor receptor 2 (VEGFR-2) in tumor tissues, and western blot was used to detect the protein expression of phosphoinositide 3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) signaling pathway in tumor tissues.</p></sec> <sec><title style='display:none'>Results</title><p>The composite microbubbles were uniform in size, and the particle size distribution was unimodal and stable, which met the requirements of ultrasound contrast agents. The loading rate of schisandrin A in Span-PEG microbubbles was 8.84 ± 0.14%, the encapsulation efficiency was 82.24±1.21%. The IC50 value of schisandrin A was 2.87 μg/mL. The drug + microbubbles + ultrasound (D+M+U) group had the most obvious inhibitory effect on Walker-256 cancer cells, the highest intracellular drug concentration, the largest reduction in tumor volume, the most obvious reduction in serum inflammatory factors, and the most obvious improvement in pathological results. The results of immunohistochemistry showed that HIF-1α, VEGF and VEGFR-2 protein decreased most significantly in D+M+U group (<italic>P</italic> &lt; 0.01). WB results showed that D+M+U group inhibited the PI3K/AKT/mTOR signaling pathway most significantly (<italic>P</italic> &lt; 0.01).</p></sec> <sec><title style='display:none'>Conclusions</title><p>Schisandrin A had an anti-tumor effect, and its mechanism might be related to the inhibition of the PI3K/AKT/mTOR signaling pathway. The schisandrin A microbubbles could promote the intake of schisandrin A in tumor cells after being destroyed at the site of tumor under ultrasound irradiation, thus playing the best anti-tumor effect.</p></sec> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/raon-2024-00192024-03-07T00:00:00.000+00:00Influence of different intraoperative fluid management on postoperative outcome after abdominal tumours resectionhttps://sciendo.com/article/10.2478/raon-2024-0015<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Background</title><p>Intraoperative fluid management is a crucial aspect of cancer surgery, including colorectal surgery and pancreatoduodenectomy.

Laminin subunit alpha 3 (LAMA3) is known to modulate tumor progression. However, the influence of LAMA3 on liver metastasis in PDAC remains unclear. This study aimed to elucidate whether LAMA3 expression is increased in PDAC with liver metastasis.</p></sec> <sec><title style='display:none'>Patients and methods</title><p>We extracted information related to LAMA3 expression levels and associated clinicopathological parameters from The Cancer Genome Atlas (TCGA) and four Gene Expression Omnibus (GEO) datasets. Clinicopathological analysis was performed; the Kaplan-Meier Plotter was used to evaluate LAMA3’s prognostic effect in PDAC. We retrospectively collected clinicopathological data and tissue specimens from 117 surgically treated patients with PDAC at the Affiliated Hospital of Qingdao University. We assessed LAMA3 expression and investigated its correlation with the clinicopathological traits, clinical outcomes, and hepatic metastasis.</p></sec> <sec><title style='display:none'>Results</title><p>Amplified expression of LAMA3 was observed in PDAC tissue compared with normal tissue in the TCGA and GEO databases. High LAMA3 expression was associated with poor overall survival (OS) and relapse-free survival (RFS) in patients with PDAC. LAMA3 expression was significantly enhanced in PDAC tissues than in adjacent tissues. Tumor tissues from patients with PDAC exhibiting liver metastasis showed higher LAMA3 expression than those without liver metastasis. High LAMA3 expression correlated with large tumor size and TNM stage. LAMA3 expression and liver metastasis were independent predictive factors for OS; the former was independently associated with liver metastasis.</p></sec> <sec><title style='display:none'>Conclusions</title><p>LAMA3 expression is elevated in patients with PDAC with liver metastasis and is a predictor of prognosis.</p></sec> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/raon-2024-00202024-03-07T00:00:00.000+00:00Impact of early integrated rehabilitation on fatigue in 600 patients with breast cancer – a prospective studyhttps://sciendo.com/article/10.2478/raon-2024-0016<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Background</title> <p>Fatigue after breast cancer treatment is a common burden that is challenging to treat. The aim of this study was to explore if such integrated rehabilitation program reduces the prevalence of chronic fatigue compared to simple, non-integrated rehabilitation.</p> </sec> <sec><title style='display:none'>Patients and methods</title> <p>The subjects of our prospective study were 600 female breast cancer patients (29–65 [mean 52 years] of age), who participated in the pilot study on the individualized integrated rehabilitation of breast cancer patients in 2019–2021 and were monitored for one year. The control group included 301 patients and the intervention group numbered 299 patients. The patients completed three questionnaires (EORTC QLQ-C30, -BR23 and NCCN): before cancer treatment, and then six and twelve months after the beginning of cancer treatment. The control group obtained the standard rehabilitation program, while the intervention group was part of the early, individualized multidisciplinary and integrated approach of rehabilitation. The rehabilitation coordinator referred patients for additional interventions (<italic>e.g.</italic>, psychologist, gynecologist, pain management team, physiotherapy, clinical nutrition team, kinesiologist-guided online training, vocational rehabilitation, general practitioner). Data on the patients’ demographics, disease extent, cancer treatment and complaints reported in questionnaires were collected and analyzed.</p> </sec> <sec><title style='display:none'>Results</title> <p>There were no differences between the control and the intervention group of patients in terms of age, education, disease extent, surgical procedures, systemic cancer treatment, or radiotherapy, and also no differences in the fatigue before the beginning of treatment. However, patients from the control group had a greater level of constant fatigue than patients from the intervention group half a year (p = 0.018) and a year (p = 0.001) after the beginning of treatment. Furthermore, a greater proportion of patients from the control group experienced significant interference with their usual activities from fatigue than from the intervention group, half a year (p = 0.042) and a year (p = 0.001) after the beginning of treatment. A multivariate logistic regression showed that one year after the beginning of treatment, the only independent factor correlated to fatigue was inclusion into the intervention group (p = 0.044). Inclusion in the intervention group was beneficial—patients from the control group were 1.5 times more likely to be fatigued.</p> </sec> <sec><title style='display:none'>Conclusions</title> <p>Early individualized integrated rehabilitation is associated with a lower prevalence of chronic fatigue or fatigue interfering with usual activities in breast cancer patients in comparison to the control group of patients.</p> </sec> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/raon-2024-00162024-03-07T00:00:00.000+00:00Dosimetry and efficiency comparison of knowledge-based and manual planning using volumetric modulated arc therapy for craniospinal irradiationhttps://sciendo.com/article/10.2478/raon-2024-0018<abstract> <title style='display:none'>Abstract</title> <sec><title style='display:none'>Background</title> <p>Craniospinal irradiation (CSI) poses a challenge to treatment planning due to the large target, field junction, and multiple organs at risk (OARs) involved.
