RESUMEN

BACKGROUND: Malignant tumors represent a significant pathology with a profound global impact on the medical system. The fight against cancer represents a significant challenge, with multidisciplinary teams identifying numerous areas requiring improvement to enhance the prognosis. Facilitating the patient's journey from diagnosis to treatment represents one such area of concern. One area of research interest is the use of various biomarkers to accurately predict the outcome of these patients. A substantial body of research has been conducted over the years examining the relationship between C-reactive protein (CRP) and malignant tumors. The existing literature suggests that combining imaging diagnostic modalities with biomarkers, such as CRP, may enhance diagnostic accuracy. METHODS: A systematic review was conducted on the PubMed and Web of Science platforms with the objective of documenting the interrelationship between CRP value and tumor grading for malignant tumors. After the application of the exclusion and inclusion criteria, 17 studies were identified, published between 2002 and 2024, comprising a total of 9727 patients. RESULTS: These studies indicate this interrelationship for soft tissue sarcomas and for renal, colorectal, esophageal, pancreatic, brain, bronchopulmonary, ovarian, and mesenchymal tumors. CONCLUSIONS: Elevated CRP levels are correlated with higher grading, thereby underscoring the potential utility of this biomarker in clinical prognostication.

RESUMEN

Liquid biopsies can accurately identify molecular alterations in patients with colorectal cancer with high concordance with tissue analysis and shorter turnaround times. Circulating tumor (ct) DNA analysis can be used for diagnosing and monitoring tumor evolution in patients with metastatic colorectal cancer who are treated with EGFR inhibitors. In this article, we reported three clinical cases to illustrate the relevance of RAS mutations identified in ctDNA samples of patients with wild-type metastatic colorectal cancer who received an EGFR inhibitor plus chemotherapy as first-line treatment. The identification of RAS mutations in these patients is one of the most frequently identified mechanisms of acquired resistance. However, detecting a KRAS mutation via liquid biopsy can be caused by inter-tumor heterogeneity or it can be a false positive due to clonal hematopoiesis. More research is needed to determine whether ctDNA monitoring may help guide therapy options in metastatic colorectal cancer patients. We performed a literature review to assess the technologies that are used for analysis of RAS mutations on ctDNA, the degree of agreement between tissue and plasma and the importance of tissue/plasma discordant cases.

RESUMEN

Metastatic colorectal cancer requires a multidisciplinary and individualized approach. Herein, we reported the case of a young woman diagnosed with metastatic rectal cancer who received an individualized multimodal treatment strategy that resulted in a remarkable survival. There were several particular aspects of this case, such as the early onset of the disease, the successful use of conversion therapy, the application of liquid biopsy to guide treatment, and the specific nature of the bone metastasis. To offer more insights for navigating such challenges in patients with metastatic colorectal cancer, we have conducted a literature review to find more data related to the particularities of this case. The incidence of early onset colorectal cancer is on the rise. Data suggests that it differs from older-onset colorectal cancer in terms of its pathological, epidemiological, anatomical, metabolic, and biological characteristics. Conversion therapy and surgical intervention provide an opportunity for cure and improve outcomes in metastatic colorectal cancer. It is important to approach each case individually, as every patient with limited liver disease should be considered as a candidate for secondary resection. Moreover, liquid biopsy has an important role in the individualized management of metastatic colorectal cancer patients, as it offers additional information for treatment decisions.

RESUMEN

Circulating cell-free DNA (ccfDNA) quantity correlates with the clinical characteristics and prognosis of various cancer types. We investigated whether ccfDNA levels and the neutrophil-to-lymphocyte ratio (NLR) have prognostic value in patients with pancreatic ductal adenocarcinoma (PDAC). Peripheral blood was collected from 82 patients with PDAC prior to any diagnostic procedure or the administration of chemotherapy. Plasma DNA was isolated, and ccfDNA concentration and NLR were determined. We found that ccfDNA levels were correlated with age and tumor burden. Moreover, higher values of NLR (≥3.31) were linked with worse overall survival (OS) (4 vs. 10 months; log rank p = 0.011), and an elevated ccfDNA concentration (≥25.79 ng/mL) was strongly associated with shorter OS (4 vs. 8 months; log rank p = 0.009). According to the results of the multivariable Cox regression analysis, the baseline concentration of ccfDNA was an independent prognostic factor for OS (HR 0.45, 95% CI 0.21-0.97, p = 0.041). Furthermore, the combination of ccfDNA levels with NLR greatly enhanced the prognostic accuracy of PDAC patients. Our study demonstrates that ccfDNA concentration and NLR are independent predictors of survival in PDAC. Subsequent studies should validate this combination as a prognostic indicator in PDAC patients and assess its utility for guiding therapeutic decisions.

RESUMEN

Therapeutic decision-making for advanced GIST liver metastases is challenging due to limited clinical evidence. This case study aims to demonstrate the survival benefit of resection in non-responsive cases. A 40-year-old male presented with abdominal pain, weight loss, altered general status, massive hepatomegaly, and intermittent melaena. He was diagnosed with stage IV GIST with the primary tumor in the ileal loop and multiple gigantic synchronous bilobar liver metastases. Despite 31 months of tyrosine-kinase inhibitor therapy post-primary tumor resection, the disease remained unresponsive. The patient was admitted to our tertiary center with significant hepatomegaly. A two-stage debulking liver resection was performed after a multidisciplinary team decision. The first operation debulked the left hemiliver through a non-anatomical ultrasound-guided resection of segments 2, 3, and 4. The second operation (7 weeks later) debulked the right hemiliver through a right posterior sectionectomy involving segments 5 and 8. Despite receiving a second line of tyrosine-kinase inhibitor therapy after surgery, the disease progressed both within and outside the liver. However, the patient survived for 55 months, with a postoperative survival benefit of 25 months. In conclusion, this case emphasizes the significant survival benefit achieved through a complex two-stage debulking liver resection for giant liver metastases, even in cases where systemic therapy fails.

RESUMEN

PURPOSE: To assess the efficacy of FOLFIRINOX(FFX), gemcitabine-based regimens (GB), and gemcitabine monotherapy (Gem) in patients with metastatic pancreatic ductal adenocarcinoma (mPDAC). METHODS: This is a retrospective study that included 83 patients with mPDAC treated with first-line chemotherapy (L1) with either FFX, GB or Gem between 2015 and 2017. Progression-free survival (PFS) for L1 and second-line chemotherapy (L2) (PFS-L1 and PFS-L2) and overall survival (OS) were estimated using the Kaplan-Meier method. RESULTS: Median PFS-L1 for FFX, GB and Gem groups was 9 months (95% (Confidence Interval) CI 2.76-15.24), 5 months (95%CI 3.44-6.56), and 5 months (95%CI 3.76-6.24), respectively (p = 0.04). OS was 14 months (95%CI 11.16-16.85), 12 months (95%CI: 9.44-11.56), and 7 months (95%CI: 5.7-8.3) for patients treated with FFX, GB, and Gem, respectively (p = 0.0001). ECOG-PS (0/1) (Hazard Ratio (HR) 6.74, p = 0.002), age > 70 years (HR 0.25, p = 0.04), body tumors (HR 2.8, p = 0.048), CA19-9 > 39 U/mL (HR 0.26, p = 0.02), and neutrophil-to-lymphocyte ratio (NLR) > 4.15 (HR 6.76, p = 0.001) were independent prognostic factors for PFS-L1. Male gender (HR 3.02, p = 0.026), ECOG-PS (0/1) (HR 4.21, p = 0.003), L1 with FFX (HR 0.255, p = 0.007), and NLR > 4.15 (HR 2.65, p = 0.04) were independent prognostic factors of OS. PFS-L2 (HR 6.91, p = 0.013) and OS-L2 (HR 6.95, p = 0.037) were significantly higher in patients first treated with FFX. CONCLUSIONS: The OS of patients who receive FFX or GB is comparable. The best PFS-L1 belongs to the FFX group. Male gender, ECOG-PS 0/1, the FFX regimen, and NLR > 4.15 were independent predictors of OS. PFS-L2 and OS-L2 were favorably impacted by L1 with FFX.

RESUMEN

We present the case of a 54-year-old female patient, diagnosed with stage IV rectal cancer, with multiple (12) synchronous liver metastases, the largest of 10 cm in diameter, bilobar distributed. The operative management consisted in simultaneous ultra-low robotic anterior resection with coloanal anastomosis (protected by ileostomy) and multiple ultrasound-guided non-anatomical liver resections (in open approach). The patient was unable to follow neoadjuvant and adjuvant chemotherapy due to the systemic side effects. The intrahepatic disease presented 2 episodes of recurrence, sanctioned by ultrasound-guided non-anatomical parenchyma sparing liver resections. In total 32 liver metastases were addressed (31 resected and 1 radiofrequency ablated). The patient presented 1 episode of lung recurrence, sanctioned by right superior lobectomy and lymphadenectomy for a singular metastasis. The patient died with disease progression both intra-, and extrahepatically after 34 months post first surgical intervention.

RESUMEN

BACKGROUND: Genetic tests are increasingly performed for the management of unresectable pancreatic cancer. For genotyping aimed samples current guidelines recommend using core specimens, although based on moderate quality evidence. However, in clinical practice among the endoscopic ultrasound (EUS) guided tissue acquisition methods, fine needle aspiration (FNA) is the most widely performed. AIM: To assess the adequacy for next generation sequencing (NGS) of the DNA yielded from EUS-FNA pancreatic adenocarcinoma (PDAC) samples. METHODS: Between November 2018 and December 2021, 105 patients with PDAC confirmed by EUS-FNA were included in the study at our tertiary gastroenterology center. Either 22 gauge (G) or 19G FNA needles were used. One pass was dedicated to DNA extraction. DNA concentration and purity (A260/280, A260/230) were assessed by spectrophotometry. We assessed the differences in DNA parameters according to needle size and tumor characteristics (size, location) and the adequacy of the extracted DNA for NGS (defined as A260/280 ≥ 1.7, and DNA yield: ≥ 10 ng for amplicon based NGS, ≥ 50 ng for whole exome sequencing [WES], ≥ 100 ng for whole genome sequencing [WGS]) by analysis of variance and t-test respectively. Moreover, we compared DNA purity parameters across the different DNA yield categories. RESULTS: Our cohort included 49% male patients, aged 67.02 ± 8.38 years. The 22G needle was used in 71% of the cases. The DNA parameters across our samples varied as follows: DNA yield: 1289 ng (inter quartile range: 534.75-3101), A260/280 = 1.85 (1.79-1.86), A260/230 = 2.2 (1.72-2.36). DNA yield was > 10 ng in all samples and > 100 ng in 93% of them (one sample < 50 ng). There were no significant differences in the concentration and A260/280 between samples by needle size. Needle size was the only independent predictor of A260/230 which was higher in the 22G samples (P = 0.038). NGS adequacy rate was 90% for 19G samples regardless of NGS type, and for 22G samples it reached 89% for WGS adequacy and 91% for WES and amplicon based NGS. Samples with DNA yield > 100 ng had significantly higher A260/280 (1.89 ± 0.32 vs 1.34 ± 0.42, P = 0.013). Tumor characteristics were not corelated with the DNA parameters. CONCLUSION: EUS-FNA PDAC samples yield DNA adequate for subsequent NGS. DNA amount was similar between 22G and 19G FNA needles. DNA purity parameters may vary indirectly with needle size.

RESUMEN

Inflammatory bowel diseases (IBD) are chronic conditions characterized by a remitting-relapsing course. Patients with IBD have an impaired quality of life and are more often affected by anxiety and depression. This study aimed to evaluate the prevalence and severity of anxiety and depression in patients with inactive IBD, and to identify factors associated with them. A total of 132 consecutive patients diagnosed with IBD for over 3 months that were in corticosteroid-free remission at the time of assessment were enrolled in this observational, cross-sectional study. Anxiety, depression, fatigue, and health-related quality of life (HR-QoL) were evaluated using the following self-administered questionnaires: HADS, Functional Assessment of Chronic Illness Therapy-Fatigue, and IBDQ 32. Symptoms of anxiety and depression were considered for HADS-A > 7 points and HADS-D > 7 points, respectively. Out of the 132 patients included, 76 (57.6%) were men. The median patient age was 38 years (interquartile range 30-47). Eighty-three patients (62.9%) were diagnosed with Crohn disease, and 49 (37.1%) with ulcerative colitis. Most of the patients were treated with biologics (85.6%). Anxiety was identified in 34.1% of patients, and two thirds of them (68.9%) had mild symptoms. A lower proportion of patients were presenting symptoms of depression (18.2%), the vast majority (91.7%) having mild forms. In the multivariate analysis, anxiety was significantly associated with fatigue [odds ratio (OR) 4.39, 95% confidence interval (CI): 1.22-15.79, P = .02] and lower HR-QoL (OR 2.46, 95% CI: 1.70-3.91, P < .001), while depression was associated with exposure to multiple biologics (OR 3.33, 95% CI: 1.01-10.97, P = .04) and fatigue (OR 9.70, 95% CI: 1.67-56.27, P = .01). In conclusion, anxiety and depression are highly prevalent in patients with IBD even during the periods of remission. Both anxiety and depression are associated with fatigue. In addition, lower HR-QoL is associated with anxiety and exposure to multiple biologics with depression.

RESUMEN

Background and Objectives: Inflammatory bowel diseases (IBD) are chronic conditions with an unpredictable course and a remitting-relapsing evolution. Fatigue is a frequent complaint in patients with IBD, affecting approximately half of the newly diagnosed patients with IBD. The aim of this study was to analyze fatigue in patients with IBD in remission. Materials and Methods: One hundred nineteen consecutive outpatients diagnosed with IBD for over 3 months that were in corticosteroid-free clinical and biochemical remission at the time of assessment were included in this cross-sectional study. Out of them, 72 (60.5%) were male; the median age was 39 years (IQR 30-47). Seventy-seven patients (64.7%) were diagnosed with Crohn's disease and forty-two (35.3%) with ulcerative colitis, with a median disease duration of 6 years (IQR 2-10). Fatigue, health-related quality of life (HR-QoL), anxiety and depression were evaluated using the following self-administered questionnaires: FACIT Fatigue, IBDQ 32 and HADS. Results: The mean FACIT-Fatigue score was 41.6 (SD ± 8.62), and 38.7% of patients were revealed as experiencing fatigue when a cut-off value of 40 points was used. The mean IBDQ 32 score was 189.4 (SD ± 24.1). Symptoms of anxiety and depression were detected in 37% and 21% of the patients, respectively. In the multivariate analysis, fatigue was significantly associated with lower HR-QoL (OR 2.21, 95% CI: 1.42-3.44, p < 0.001), symptoms of anxiety (OR 5.04, 95% CI: 1.20-21.22, p = 0.008), female sex (OR 3.32, 95% CI: 1.02-10.76, p = 0.04) and longer disease duration (OR 1.13, 95% CI: 1.01-1.27, p = 0.04). Conclusions: Fatigue is highly prevalent even in patients with inactive IBD and is correlated with lower HR-QoL and anxiety, as well as with clinical factors such as longer disease duration and female sex.

RESUMEN

Background and Objectives: Colorectal cancer (CRC) is a leading cause of cancer-related mortality and morbidity worldwide. Bevacizumab was approved for the treatment of metastatic colorectal cancer (mCRC) based on favorable benefit-risk assessments from randomized controlled trials, but evidence on its use in the real-world setting is limited. The aim of the current study is to evaluate the outcomes and safety profile of bevacizumab in mCRC in a real-world setting in Romania. Patients and Methods: This was an observational, retrospective, multicentric, cohort study conducted in Romania that included patients with mCRC treated with bevacizumab as part of routine clinical practice. Study endpoints were progression-free survival, overall survival, adverse events, and patterns of bevacizumab use. Results: A total of 554 patients were included in the study between January 2008 and December 2018. A total of 392 patients (71%) received bevacizumab in the first line and 162 patients (29%) in the second line. Bevacizumab was mostly combined with a capecitabine/oxaliplatin chemotherapy regimen (31.6%). The median PFS for patients treated with bevacizumab was 8.4 months (interquartile range [IQR], 4.7-15.1 months) in the first line and 6.6 months (IQR, 3.8-12.3 months) in the second line. The median OS was 17.7 months (IQR, 9.3-30.6 months) in the first line and 13.5 months (IQR, 6.7-25.2 months) in the second line. Primary tumor resection was associated with a longer PFS and OS. The safety profile of bevacizumab combined with chemotherapy was similar to other observational studies in mCRC. Conclusions: The safety profile of bevacizumab was generally as expected. Although the PFS was generally similar to that reported in other studies, the OS was shorter, probably due to the less frequent use of bevacizumab after disease progression and the baseline patient characteristics. Patients with mCRC treated with bevacizumab who underwent resection of the primary tumor had a higher OS compared to patients with an unresected primary tumor.

RESUMEN

Hepatitis C viral (HCV) treatment has rapidly advanced with the use of direct-acting antivirals (DAA), and many patients achieve sustained virological response (SVR). Although the risk of liver tumors is greatly reduced, there are still patients who achieve SVR but will progress to hepatocellular carcinoma (HCC). HCV infection is also a known risk for cholangiocellular carcinoma (CLC), although it is considered a relative infrequent liver malignancy. We report a series of five cases of CLC in patients that achieved SVR after HCV treatment with DAA. There were three women and two males with a median age of 62 years (range 49 to 77 years). Four patients had liver cirrhosis at the time of their HCV treatment. The interval from achieving SVR until CLC diagnosis varied, ranging from 4 to 36 months (median=12). Three patients presented with advanced disease and had extrahepatic spread at the time of their diagnosis. One patient had a resectable tumor, with no recurrence 4 years later. In one case, the tumor was initially considered an atypical HCC and was treated by radiofrequency ablation. Three years later, she was diagnosed with a large tumor recurrence that was demonstrated to be a CLC on liver biopsy. The last two patients were older males with HCV compensated cirrhosis diagnosed with CLC more than two years after achieving SVR. Palliative chemotherapy was started in both. Only a handful of CLC cases have been reported in HCV patients after SVR. Clinicians should take into account the possible development of an aggressive CLC.

RESUMEN

Ovarian cancer is considered one of the most aggressive and deadliest gynecological malignancies worldwide. Unfortunately, the therapeutic methods that are considered the gold standard at this moment are associated with frequent recurrences. Survival in ovarian cancer is associated with the presence of a high number of intra tumor infiltrating lymphocytes (TILs). Therefore, immunomodulation is considered to have an important role in cancer treatment, and immune checkpoint inhibitors may be useful for restoring T cell-mediated antitumor immunity. However, the data presented in the literature until now are not sufficient to allow for the identification and selection of patients who really respond to immunotherapy among those with ovarian cancer. Although there are some studies with favorable results, more prospective trials are needed in this sense. This review focuses on the current and future perspectives of PD-1/L1 blockade in ovarian cancer and analyzes the most important immune checkpoint inhibitors used, with the aim of achieving optimal clinical outcomes. Future studies and trials are needed to maximize the efficacy of immune checkpoint blockade therapy in ovarian cancer, as well as in all cancers, in general.

RESUMEN

BACKGROUND: Neuroendocrine neoplasms are a heterogeneous group of tumors that raise challenges in terms of diagnosis, treatment and monitoring. Despite continuous efforts, no biomarker has showed satisfying accuracy in predicting outcome or response to treatment. METHODS: We conducted a systematic review to determine relevant circulating biomarkers for angiogenesis in neuroendocrine tumors. We searched three databases (Pubmed, Embase, Web of Science) using the keywords "neuroendocrine" and "biomarkers", plus specific biomarkers were searched by full and abbreviated name. From a total of 2448 publications, 11 articles met the eligibility criteria. RESULTS: VEGF is the most potent and the most studied angiogenic molecule, but results were highly controversial. Placental growth factor, Angiopoietin 2 and IL-8 were the most consistent markers in predicting poor outcome and aggressive disease behavior. CONCLUSIONS: There is no robust evidence so far to sustain the use of angiogenic biomarkers in routine practice, although the results show promising leads.

RESUMEN

Patients with cancer have been shown to have increased risk of COVID-19 severity. We previously built and validated the COVID-19 Risk in Oncology Evaluation Tool (CORONET) to predict the likely severity of COVID-19 in patients with active cancer who present to hospital. We assessed the differences in presentation and outcomes of patients with cancer and COVID-19, depending on the wave of the pandemic. We examined differences in features at presentation and outcomes in patients worldwide, depending on the waves of the pandemic: wave 1 D614G (n = 1430), wave 2 Alpha (n = 475), and wave 4 Omicron variant (n = 63, UK and Spain only). The performance of CORONET was evaluated on 258, 48, and 54 patients for each wave, respectively. We found that mortality rates were reduced in subsequent waves. The majority of patients were vaccinated in wave 4, and 94% were treated with steroids if they required oxygen. The stages of cancer and the median ages of patients significantly differed, but features associated with worse COVID-19 outcomes remained predictive and did not differ between waves. The CORONET tool performed well in all waves, with scores in an area under the curve (AUC) of >0.72. We concluded that patients with cancer who present to hospital with COVID-19 have similar features of severity, which remain discriminatory despite differences in variants and vaccination status. Survival improved following the first wave of the pandemic, which may be associated with vaccination and the increased steroid use in those patients requiring oxygen. The CORONET model demonstrated good performance, independent of the SARS-CoV-2 variants.

RESUMEN

BACKGROUND: Colon cancer is one the most common forms of cancer in both sexes. Due to important progress in the field of early detection and effective treatment, colon and rectal cancer survivors currently account for 10% of cancer survivors worldwide. However, the effects of anti-cancer treatments, especially oxaliplatin-based chemotherapy, on the quality of life (QoL) have been less evaluated. Although the incidence of severe chemotherapy-induced neuropathy (CIPN) in clinical studies is below 20%, data from real-world studies is scarce, and CIPN is probably under-reported due to patient selection and the patients' fear that reporting side-effects might lead to treatment cessation. AIM: To determine the impact of CIPN on QoL in colorectal cancer patients with a recent history of oxaliplatin-based chemotherapy. METHODS: We performed a prospective cross-sectional study in two major Romanian oncology tertiary hospitals-the Regional Institute of Oncology Iași (Iasi, Romania) and the Fundeni Clinical Oncology Institute (Bucharest, Romania). All consecutive patients with colon or rectal cancer, undergoing Oxaliplatin-based chemotherapy that consented to enroll in the study, were assessed by means of two questionnaires-the EORTC QQ-CR29 (quality of life in colon and rectal cancer patients) and the QLQ-CIPN20 (assessment of neuropathy). Several demographical, social, clinical and treatment data were also collected. Statistical analysis was performed by means of SPSS v20. The student t test was used to assess the relationship between the QLQ-CIPN20 and QLQ-CR29 results. Kaplan Meyer-curves were used to report 3-year progression-free survival (PFS) in patients that discontinued chemotherapy vs those that completed the recommended course. RESULTS: Of the 267 patients that fulfilled the inclusion criteria in the pre-specified time frame, 101 (37.8%) agreed to participate in the clinical study. At the time of the enrolment in the study, over 50% of the patients had recently interrupted their oxaliplatin-based chemotherapy, most often due to neuropathy. Almost 85% of the responders reported having tingling or numbness in their fingers or hands, symptoms that were associated with pain in over 20% of the cases. When comparing the scores in the two questionnaires, a statistically significant relationship (P < 0.001) was found between the presence of neuropathic symptoms and a decreased quality of life. This correlation was consistent when the patients were stratified by sex, disease stage, comorbidities and the presence of stoma or treatment type, suggesting that neuropathy in itself may be a reason for a decreased quality of life. At the 3 year final assessment, median recurrence-free survival in stage III patients was 26.88 mo. When stratified by completion of chemotherapy, median recurrence free-survival of stage III patients that completed chemotherapy was 28.27 mo vs 24.33 mo in patients that discontinued chemotherapy due to toxicity, a difference that did not reach statistical significance. CONCLUSION: CIPN significantly impacts QoL in colorectal cancer patients. CIPN is also the most frequent reason for treatment discontinuation. Physicians should actively assess for CIPN in order to prevent chronic neuropathy.

RESUMEN

Background and Objectives: Complete mesocolon excision and high vascular ligation have become a standard procedure in the treatment of colon cancer. The transverse colon has certain embryological and anatomical particularities which require special attention in case of oncological surgeries. Proximal transverse colon cancer (TCC) can metastasize to the lymph nodes in the gastrocolic ligament. The aim of this study is to assess the tumor involvement of these lymph nodes and to determine the applicability of gastrocolic ligament lymph nodes dissection as the standard approach for proximal transverse colon cancer. Materials and Methods: this study analyzes the cases of patients admitted to the Surgery Department, diagnosed with proximal transverse colon cancer, with tumor invasion ≥ T2 and for which complete mesocolon excision with high vascular ligation and lymphadenectomy of the gastrocolic ligament (No. 204, 206, 214v) were performed. Results: A total of 43 cases operated during 2015−2020 were included in the study. The median total number of retrieved central lymph nodes was 23 (range, 12−38), that had tumor involvement in 22 cases (51.2%). Gastrocolic ligament tumor involvement was found in 5 cases (11.6%). The median operation time was 180 min, while the median blood loss was 115 mL (range 0−210). The median time of hospitalization was 6 days (range, 5−11). Grade IIIA in the Clavien-Dindo classification was noticed in 3 patients, with no mortality. Upon Kaplan−Meier analysis, tumors > T3 (p < 0.016) and lymph node ratio < 0.05 (p < 0.025) were statistically significant. Conclusions: lymph node dissection of the gastrocolic ligament in patients with advanced proximal transverse colon cancer may improve the oncological outcome in T3/T4 tumors, and therefore standardization could be feasible

RESUMEN

PURPOSE: Patients with cancer are at increased risk of severe COVID-19 disease, but have heterogeneous presentations and outcomes. Decision-making tools for hospital admission, severity prediction, and increased monitoring for early intervention are critical. We sought to identify features of COVID-19 disease in patients with cancer predicting severe disease and build a decision support online tool, COVID-19 Risk in Oncology Evaluation Tool (CORONET). METHODS: Patients with active cancer (stage I-IV) and laboratory-confirmed COVID-19 disease presenting to hospitals worldwide were included. Discharge (within 24 hours), admission (≥ 24 hours inpatient), oxygen (O2) requirement, and death were combined in a 0-3 point severity scale. Association of features with outcomes were investigated using Lasso regression and Random Forest combined with Shapley Additive Explanations. The CORONET model was then examined in the entire cohort to build an online CORONET decision support tool. Admission and severe disease thresholds were established through pragmatically defined cost functions. Finally, the CORONET model was validated on an external cohort. RESULTS: The model development data set comprised 920 patients, with median age 70 (range 5-99) years, 56% males, 44% females, and 81% solid versus 19% hematologic cancers. In derivation, Random Forest demonstrated superior performance over Lasso with lower mean squared error (0.801 v 0.807) and was selected for development. During validation (n = 282 patients), the performance of CORONET varied depending on the country cohort. CORONET cutoffs for admission and mortality of 1.0 and 2.3 were established. The CORONET decision support tool recommended admission for 95% of patients eventually requiring oxygen and 97% of those who died (94% and 98% in validation, respectively). The specificity for mortality prediction was 92% and 83% in derivation and validation, respectively. Shapley Additive Explanations revealed that National Early Warning Score 2, C-reactive protein, and albumin were the most important features contributing to COVID-19 severity prediction in patients with cancer at time of hospital presentation. CONCLUSION: CORONET, a decision support tool validated in health care systems worldwide, can aid admission decisions and predict COVID-19 severity in patients with cancer.

RESUMEN

Background and Objectives: Inflammatory bowel diseases (IBD) are chronic conditions with an unpredictable evolution that can have a negative impact on patients' quality of life (QoL). Even though patients in remission have a better QoL compared to patients with active disease, they still have a lower QoL compared to healthy people. The aim of this study is to identify the factors that are associated with a lower QoL in patients with IBD in clinical remission, in a tertiary IBD center in Romania. Materials and Methods: Ninety-seven adult patients with a current diagnosis of IBD for over 3 months who were in clinical remission were enrolled in this study. Pregnant women, patients with ostomy, perianal disease, extraintestinal manifestations or other significant comorbidities were excluded. Out of the 97 patients, 63.9% were men. The median age was 39 years (IQR 29−47), and the median disease duration was 5 years (IQR 2−10). Disease activity was assessed using the SCCAI score for ulcerative colitis and HBI score for Crohn's disease. Remission was defined for SCCAI score ≤ 1 and HBI score ≤ 4. The health-related quality of life (HR-QoL) was assessed using the IBDQ32 score. FACIT-Fatigue was used to evaluate the level of fatigue. Patients with symptoms of anxiety or depression were identified with the HADS score. Symptoms of anxiety were considered when HADS-A >7 points and symptoms of depression when HADS-D >7 points. Results: Sixty-five patients (67%) were diagnosed with CD and the remaining 32 (33%) with UC. Ninety-three patients (95.9%) were on biological therapy. The mean IBDQ score (total score) was 190.54 points (SD +/− 8.2). The mean FACIT Fatigue score was 42.5 (SD +/− 8.2), with 6.2% of patients suffering from severe fatigue (FACIT Fatigue < 30 points). A total of 33% of patients had symptoms of anxiety and 16.5% of depression. Exposure to more than one biologic therapy (p = 0.02), fatigue (p < 0.001) and symptoms of anxiety (p < 0.001) were associated with a lower HR-QoL in the multivariate analysis. Female patients, patients with Crohn's disease, patients with anemia and patients with symptoms of depression also had a lower HR-QoL, but this did not reach statistical significance in our study. Conclusions: Exposure to a higher number of biological agents (patients that switched multiple biologics), the presence of fatigue and symptoms of anxiety impair the HR-QoL of patients with IBD in clinical remission. Further studies should assess in a prospective manner whether early identification of these factors with prompt clinical interventions could lead to a better HR-QoL in these patients.

RESUMEN

In the last decades, anthropogenic drivers have significantly influenced the natural climate variability of Earth's atmosphere. Climate change has become a subject of major interest for different levels of our society, such as national governments, businesses, local administration, or citizens. While national and local policies propose mitigation and adaptation strategies for different sectors, public perception is a key component of any implementation plan. This study investigates the CC perception in Romania, based on a national-scale online survey performed in the spring of 2020, aiming to outline the prominence of environmental and CC issues, level of information and interest, perceived causes, changes perceived in meteorological phenomena at the regional scale, perceived impacts, and the psychological representation of the CC. The study investigates single causal factors of perception. We found that particularly (i) the regional differences on climate change intensity strongly bias the perception of CC causes; (ii) age is very likely to influence the acceptance of CC, the importance of environmental issues, and the levels of information and interest; while (iii) age, gender, and place of residence (rural-urban) are very likely to control the changes perceived in the occurrence of various meteorological phenomena, and their impact. This research is the first statistically relevant analysis (± 4%, statistical significance) developed at national and regional scales and the only study of climate change perception performed during the COVID-19 pandemic in Romania. Its results may represent the baseline for more in-depth research. Supplementary Information: The online version contains supplementary material available at 10.1007/s00704-022-04041-4.
