RESUMEN
INTRODUCTION: This is a phenomenologically designed qualitative study conducted to explore and conceptualize the problems experienced by intensive care nurses caring for patients undergoing continuous renal replacement therapy. METHODS: Face-to-face, semi-structured interviews were conducted with the participants. The interviews were transcribed verbatim, then thematic analysis was conducted. RESULTS: The study was conducted 12 intensive care nurses. As a result, 3 main and 6 sub-themes were identified. The themes identified were changing routines, uncertainty in terms of patient benefit, and need for adaptation. CONCLUSION: It was found that nurses experienced challenges in providing care to patients undergoing continuous renal replacement therapy, spent more effort to prevent complications, and lacked information on the subject. It is recommended to consider institutional and individual actions to meet the educational needs of nurses for implementing continuous renal replacement therapy.
RESUMEN
BACKGROUND: Diabetes Mellitus (DM) is a metabolic disease with a high morbidity and mortality and increasing in prevalence all over the world. Due to the hypoxic, ischemic, inflammatory, and infective environment in DM, diabetic foot ulcers have been treated with medico-surgical interventions and adjuvant hyperbaric oxygen Therapy (HBOT). The purpose of this study was to evaluate the effects of HBOT on hematological indices and biochemical parameters in patients with diabetic foot. METHODS: The study group was formed from the file records of 103 male patients who applied to Yunus Emre State Hospital HBOT Center between September 1, 2016 and December 31, 2020, and were treated HBOT with a multidisciplinary approach. RESULTS: There were negative low correlations between number of HBOT sessions and Mean Corpuscular Hemoglobin (MCH) (Pâ =â .037, râ =â -0.207) and Blood Urea Nitrogen (BUN) (Pâ =â .037, râ =â -0.222). White Blood Cell Count (WBC), Neutrophils (NEU), Monocytes (MON), Platelet Count (PLT), and Plateletcrit (PTC) parameters were found to be decreased, and an increase in lymphocytes (LYM), Eosinophils (EOS), Mean Corpuscular Hemoglobin Concentration (MCHC), and Red Cell Distribution Width (RDW) parameters were detected after the treatments (Pâ <â .05). Again, after the treatment, glucose (Glu), C-Reactive Protein (CRP), direct bilirubin, and total protein (TP) levels were decreased, and uric acid (UA) levels increased (Pâ <â .05). CONCLUSION: HBOT improved hematological indices in patients and had a beneficial effect on biochemical parameters, particularly Glu and CRP levels. Adjuvant HBOT alleviates diabetic inflammation and has a beneficial effect on diabetic patient treatment.

The prognosis of patients with advanced HCC can vary widely depending on factors such as the stage of the cancer, the patient's overall health, and treatment regimens. This study aimed to investigate survival outcomes and associated factors in patients with hepatocellular carcinoma (HCC). In this retrospective study, data from 23 medical oncology clinics were analyzed. Progression-free survival (PFS) and overall survival (OS) values were estimated using the Kaplan-Meier method. Prognostic factors associated with survival which were identified in univariate analysis were subsequently evaluated in a multivariate Cox-regression survival analysis was conducted using the backward stepwise (Conditional LR) method to determine the independent predictors of PFS and OS. Of 280 patients, 131 received chemotherapy and 142 received sorafenib, 6 received atezolizumab plus bevacizumab and 1 received nivolumab for first-line setting. The median follow-up time was 30.4 (95%CI 27.1-33.6) months. For-first line, median PFS was 3.1 (95%CI2.7-3.5) months, and it was significantly longer in patients who received sorafenib or atezolizumab-bevacizumab or nivolumab (PFS 5.8 (95%CI 4.2-7.5) than in those received chemotherapy (PFS 2.1 (95%CI 1.9-2.3) in the first-line setting (p < 0.001). Multivariate analysis revealed that male gender (HR: 2.75, 95% CI: 1.53-4.94, p = 0.01), poor ECOG performance score (HR: 1.88, 95% CI: 1.10-3.21, p = 0.02), higher baseline AFP level (HR: 2.38, 95% CI: 1.54-3.67, p < 0.001) and upfront sorafenib treatment (HR,0.38; 95% CI: 0.23-0.62, p < 0.001) were significantly associated with shorter PFS. The median OS was 13.2 (95%CI 11.1-15.2) months. It was significantly longer in patients who received sorafenib or atezolizumab-bevacizumab or nivolumab in the first-line setting followed by TKIs (sorafenib or regorafenib, OS 18.6 (95%CI 13.8-23.5)) compared to those who received chemotherapy (OS 10.3 (95%CI 6.6-14.1)) in the first-line setting. The multivariate analysis revealed that upfront chemotherapy treatment approach, male gender (HR: 1.77, 95% CI: 1.07-2.94, p = 0.02), poor ECOG performance score (HR: 1.96, 95% CI: 1.24-3.09, p = 0.004) and Child-Pugh score, presence of extrahepatic disease (HR: 1.54, 95% CI: 1.09-2.18, p = 0.01), and higher baseline AFP value (HR: 1.50, 95% CI: 1.03-2.19, p = 0.03) were significantly associated with poor prognosis. Additionally, regarding of treatment sequence, upfront sorafenib followed by regorafenib showed a significantly lower risk of mortality (HR: 0.40, 95% CI: 0.25-0.66, p < 0.001). Sorafenib followed by regorafenib treatment was associated with a significantly lower risk of mortality rather than upfront sorafenib followed by BSC group or upfront chemotherapy followed by TKIs. These findings underscore the importance of the optimal treatment sequences to improve survival in patients with advanced HCC.
RESUMEN
INTRODUCTION: Hyponatremia is the most common electrolyte disorder often present in peritoneal dialysis (PD) patients. The aim of this retrospective study was to investigate the effect of hyponatremia on mortality in patients undergoing PD. METHODS: The health records of adult individuals with an inserted PD catheter identified via the centralized national e-health database were used. RESULTS: The mean age of the 846 patients included in the study was 52.48 years (±14.6). The mean sodium level was 136.51 mEq/L. Sodium levels <137 mEq/L were associated with higher death risk independent of comorbidities. There was a 0.821 times less reduction in mortality for each mEq /L increase in serum sodium. CONCLUSION: Our study provides evidence that monitoring and adjusting serum sodium levels is crucial in managing PD patients with hyponatremia, as low serum sodium level was found to be a significant and independent predictor of mortality.

The aim of our study was to evaluate the incidence of KRAS/NRAS and BRAF mutations, analyze molecular patterns, and investigate associations with clinical parameters of these mutations in CRC KRAS/NRAS and BRAF mutations analyzed by next-generation sequencing. The detection rates of these mutations and patients' demographics were recorded and the relationship between them was evaluated using the chi-square test. KRAS mutation was detected in 332 of 694 patients, while the mutation rates in KRAS exons 2/3 and 4 were 39.6%/3.2% and 5%, respectively. The most common mutation pattern was KRAS G12D. Five atypical variants were detected: V14I in KRAS exon 2, A18D, Q22K and T50I in exon 3, and T148P in exon 4. NRAS mutation was detected in 29 (4.5%) patients. One atypical variant L80W was detected in NRAS exon 3. BRAF mutation was seen in 37 (5.3%) patients, with BRAFV600E (83.8%) being the most common mutation pattern. NRAS mutation was significantly more frequent in patients > 64 years of age, BRAF mutation in women, and NRAS/BRAF mutations in right colon tumors. Grouping BRAF mutations into BRAFV600E and BRAFnon-V600E and their analysis according to specific tumor localizations showed that all four BRAFnon-V600E mutations originated in the rectum. In our study, KRAS exon 2 and other RAS mutation rates were higher than in the literature, while the BRAF v.600E mutation rate was similar. NRAS and BRAF mutations were significantly more frequent in the right colon. BRAF mutation was more common in women and in the right colon.
RESUMEN
INTRODUCTION: This study aimed to assess the role of the adjusted PNI-IMDC risk scoring system in stratifying the intermediate group of metastatic RCC patients who received TKIS in the first-line setting. METHODS: A total of 185 patients were included. The adjusted PNI and IMDC model was used to divide the intermediate group into two groups: intermediate PNI-high and intermediate PNI-low groups. The statistical data were analyzed using Kaplan-Meier and Cox regression analysis. RESULTS: The results showed that the adjusted PNI-IMDC risk score, classic IMDC, and PNI had similar prognostic values. Adjusted PNI-IMDC risk score might be used for a more homogeneous differentiation of the classic intermediate group. On the other hand, multivariate analysis revealed that the presence of nephrectomy, adjusted favorable/intermediate (PNI-high) group, ECOG performance score, and presence of bone metastasis were independent predictors of OS. CONCLUSIONS: Pre-treatment PNI, as a valuable and potential add-on biomarker to the adjusted PNI-IMDC classification model, can be helpful for establishing an improved prognostic model for intermediate group mRCC patients treated with first-line TKISs. Further validation studies are needed to clarify these findings.
RESUMEN
Aim: In this study, we aimed to analyze the effect of prognostic nutritional index and neutrophile lymphocyte ratio on the overall survival (OS) in patients treated with regorafenib. Materials and Methods: Metastatic colorectal cancer (CRC) patients who treated with regorafenib between 2016 and 2020 in a single center were evaluated retrospectively. ROC analysis was used for neutrophile lymphocyte ratio (NLR's) and prognostic nutritional index (PNI's) optimum cut-off value. The relationship between OS with PNI and NLR was investigated. Results: Fifty-two patient's data were analyzed. The median age was 57 years, 22 (41.5%) of the patients were female. The optimal cut-off value of PNI for OS was 45.7 according to ROC curve analysis. The median NLR value was accepted as 2.7. Median OS was 8.3 months. Patients who have high PNI value than 45.7 had longer OS (12.09 months vs. 6.31 months hazard ratio [HR]: 0.37 95% confidence interval [CI]: 0.19-0.73 P = 0.003) and there was a tendency for longer OS with low NLR value then median (12.05 months vs. 6.14 months HR: 0.54 95% CI: 0.29-1.23 P = 0.057). Primary tumor resected patients had longer OS than nonresected patients (12.05 months vs. 6.30 months HR: 0.34 95% CI: 0.17-0.66 P = 0.001). In multivariate analysis, high PNI value more than 45.7 (HR: 0.40 95% CI: 0.18-0.88 P = 0.02) and resection of the primary tumor (HR: 0.40 95% CI: 0.21-0.80 P = 0.01) were the only independent factors for longer OS. Conclusion: Metastatic CRC patients with high pretreatment PNI and primary tumor resected are more likely to have longer OS with regorafenib. PNI is more reliable index than NLR to predict OS in metastatic CRC patients treated with regorafenib.

BACKGROUND: Most of the studies on salivary gland cancers are limited for various reasons such as being single-center, small number of patients, including only major or minor SGCs, or only including epidemiological data. METHODS: A total of 37 medical oncology clinics from different regions of Turkey participated in this retrospective-multicenter study. The analyzed data included clinical and demographical features, primary treatment, metastasis localizations, and treatments and includes certain pathologic features. RESULTS: The study included data from a total of 443 SGCs. 56.7% was in major salivary glands and 43.3% was in minor salivary glands. Distant metastasis in the major SGCs was statistically significantly more common than in the minor SGCs, locoregional recurrence was statistically significantly more common in the minor SGCs than in the major SGCs (p = 0.003). CONCLUSIONS: Epidemiological information, metastasis and recurrence patterns, treatment modalities, and survival analysis of the patients over 20 years of follow-up are presented.

Crescentic IgA nephropathy (IgAN) with the positivity for antineutrophilic cytoplasmic antibody (ANCA) is a novel and uncommon entity. The optimal management of this condition is not well-defined. We report a 49-years-old woman with complaints of skin rash and swelling of lower limbs. She had hematuria, proteinuria and, progressive renal impairment with positive myeloperoxidase (MPO)-ANCA test. A renal biopsy revealed MPO-ANCA-associated crescentic IgAN. Induction therapy was intravenous methylprednisolone, cyclophosphamide and, therapeutic plasma exchange (TPE). An unexpected disease flare-up was observed during induction immunosuppressive therapy which regressed after long-term TPE. The patient experienced a full renal recovery after treatment with long-term TPE, cyclophosphamide, and corticosteroids. DOI: 10.52547/ijkd.6490.

OBJECTIVE: To evaluate clinical and demographic characteristics and the results of cytotoxic treatments of KRASG12C, KRASother, and next-generation sequencing (NGS) panel negative patients. METHODS: NGS data of 1264 patients with non-small cell lung cancer were retrospectively evaluated. Among these patients, the mutation distributions of 1081 patients with metastatic lung adenocarcinoma were analyzed. A total of 150 patients with negative NGS panel or mutant KRAS followed up in our clinic were included. Clinical features, overall survival, first-line chemotherapy responses, and progression-free survival of NGS panel negative, KRASG12C, and KRASother groups were compared. RESULTS: In 1081 patients who underwent NGS from tumor tissue with the diagnosis of metastatic lung adenocarcinoma, 296 (27%) NGS panel negative and 276 (26%) KRAS mutant patients were detected. Among these patients, 150 patients whose data were available were 71 (47.3%) NGS panel negative, 54 (36%) KRASother, and 25 (16.7%) KRASG12C. Clinical features, brain metastasis, and first-line chemotherapy response were similar among groups. Bone metastases were detected more often in the NGS panel negative group (p = 0.03). The median follow-up was 8.4 months. Overall, 107 deaths had occurred at the time of analysis. There was no difference in overall survival (p = 0.56) or progression-free survival (p = 0.71) among NGS panel negative, KRASother, and KRASG12C patients. CONCLUSION: There is no difference in overall survival, first-line chemotherapy response, or progression-free survival among patients with NGS panel negative, KRASG12C, or KRASother metastatic lung adenocarcinoma. Bone metastases were observed more frequently in the NGS panel negative group.

PURPOSE: We aimed to identify the prognostic and predictive values of post-treatment prognostic nutritional index (PNI) and PNI dynamics in nasopharyngeal cancer patients (NPC) in this study. METHODS: One hundred seven non-metastatic NPC patients were included. PNI was calculated by using the following formula: [10 × serum albumin value (gr/dL)] + [0.005 × total lymphocyte count (per mm3)]. ROC analysis was used for determining prognostic PNI values and univariate and multivariate statistical analyses for prognostic characterization of PNI. RESULTS: The statistically significant cut-off values for pre- and post-treatment PNI were 50.65 and 44.75, respectively. Of the pre-treatment PNI analysis, PNI ≤ 50.65 group had shorter loco-regional recurrence-free survival (LRRFS), distant metastasis-free survival (DMFS), and overall survival (OS). Furthermore, for post-treatment PNI analysis, PNI ≤ 44.75 group had shorter LRRFS and OS. In univariate analysis, only pre-treatment PNI was associated with LRRFS and DMFS, while pre- and post-treatment PNI were both associated with OS. In multivariate analysis, both PNI were independent prognostic markers for OS. In the combined analysis, pre- and post-treatment PNI, differences between the groups were statistically significant, and the PNI dynamics was an independent prognostic indicator for OS. CONCLUSION: PNI is a useful, independent prognostic marker for non-metastatic NPC patients. It is used for either pre- or post-treatment patients. Furthermore, changes in pre-treatment PNI value after curative treatment is a significant indicator for OS.

BACKGROUND: Transverse colon cancer (TCC) is a rare condition that accounts for 10% of all colon cancers. TCC was accepted more likely right-sided colon cancers. We aimed to investigate whether TCC differs from other colon tumors by using clinical, pathological, and molecular prognostic factors known to be important in colon cancer and if it differs in its own anatomical structure. PATIENTS AND METHODS: We evaluated local and locally advanced TCC patients between 2007 and 2020 years for demographics data, symptoms, treatment status, and histopathological and molecular features. RESULTS: Overall, 107 TCC patients were included in this study. According to the molecular data analysis of 44, 35, and 23 patients for MSI, RAS, and BRAF status, respectively, 7 (15.9%) were MSI-H, 13 (37.1%) were RAS mutant, and 11 (47.8%) had BRAF V600E mutation. The median follow-up time was 31.5 months. Median disease-free survival (DFS) was 5.19 months, and median OS was 88.3 months for the whole study population. The tumor stage was the most significant prognostic factor for DFS and OS. Although BRAF mutation was not a significant marker for DFS, it was an independent prognostic marker for OS (HR 3.90 95% CI 1.42-10.7). There were no statistically significant differences between proximal two-thirds and distal one-third tumor location. CONCLUSION: TCC has molecular features and prognostic factors more likely RCC and no differences between proximal and distal sub-parts. BRAF V600E mutation status is an independent predictor of survival even in the early stages of TCC.

PURPOSE: In this study, we aimed to determine the factors which affect post-progression survival (PPS) and overall survival (OS) in patients with metastatic colorectal cancer. METHODS: 87 patients with metastatic colorectal cancer had been followed up with palliative care due to disease progression or ECOG performance status after receiving at least two cycles of chemotherapy. PPS was estimated as the time between the last progression date and last control or death date in patients who were followed up with palliative care. RESULTS: 87 patients with metastatic colorectal cancer were included in the study. Evaluation with multivariate analysis of factors affecting PPS revealed a significantly longer PPS (10.8 weeks) in patients with ECOG score 0 or 1 than the PPS of patients with ECOG score 2-5 (3 weeks) (p=0.01). It was also found that PPS was 14.4 weeks in patients with CEA levels <5ng/ml,while it was 6.7 weeks in patients with CEA levels ≥5 ng/ml (p=0.001) and PPS was 13.7 weeks in patients with controlled disease after first-line chemotherapy while it was 8 weeks in patients with progression (p=0.03); both were statistically significant. No significant association was found between PPS and age, gender, tumor location, sites of metastasis, and RAS status. CONCLUSION: ECOG performance status score of 0-1, CEA levels below 5 ng/ml, and disease control with first-line chemotherapy are related to longer PPS in patients with metastatic colorectal cancer.

PURPOSE: To demonstrate whether early changes in systemic inflammatory markers are related with pazopanib treatment response in soft tissue sarcoma and renal cell carcinoma. METHODS: Forty-one patients with metastatic clear cell renal carcinoma (mRCC) (n=22) and advanced stage soft tissue sarcoma (STS) (n=19) were assessed. Systemic inflammatory markers such as neutrophils, lymphocytes, c-reactive protein (CRP), mean platelet volume (MPV), lactate dehydrogenase (LDH) and neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) at both baseline and 1-month of pazopanib treatment were obtained and their relation with the first radiological response about 3-months later after pazopanib treatment was evaluated. RESULTS: Disease control rate (DCR) at the first initial radiological evaluation was 58.5 % for all, it was 77.3% for the RCC group and 36.8% in the STS group. Serum neutrophil, NLR and CRP levels were significantly decreased from baseline in RCC patients who had DCR with pazopanib treatment. Also, serum CRP levels after pazopanib treatment was significantly lower in RCC patients who had DCR (+) rather than those who progressed. CONCLUSIONS: Early decline in serum CRP, neutrophil and NLR levels in RCC patients who received pazopanib at the first month was significantly associated with disease control, assuming a predictive role for the first radiological assessment. However, there was no significant association between change in serum inflammatory marker levels and disease control in STS patients.

PURPOSE: In this study, we aimed to compare the data of sunitinib and pazopanib used in the first-line treatment of metastatic renal cell carcinoma (RCC) cases and to evaluate the effective factors in terms of survival. METHODS: The records of 125 patients with metastatic RCC admitted between January 2005 and February 2018 were retrospectively analyzed and 63 patients who received pazopanib or sunitinib were included in the study while 62 patients were excluded due to insufficient data. Clinical and histological characteristics, treatment responses, progression-free survival (PFS), and overall survival (OS) of the patients were compared. RESULTS: Patients with metastatic RCC who received pazopanib or sunitinib as tyrosine kinase inhibitors (TKI) in first-line treatment were analyzed; 45 (71.4%) were male while 18 (28.6%) were female, and the median age was 60. 43 (68.3%) patients were treated with sunitinib and 20 (31.7%) with pazopanib. PFS ââof pazopanib and sunitinib were 10.6 and 7.2 months, respectively. Median OS was 14.5 months in patients receiving pazopanib and 13.6 months in those receiving sunitinib. There was no statistical difference in PFS and OS between both treatments. The median OS of clear-cell RCC was 15.2 months, while of non-clear-cell RCC was 7.7months. CONCLUSIONS: High ECOG score, non-clear-cell histology, presence of liver metastasis in metastatic RCC patients were found to be associated with shorter OS and PFS. Sunitinib and pazopanib produced similar OS and PFS rates in first-line treatment of metastatic RCC.

PURPOSE: We aimed to assess whether skeletal muscle loss during EGFR thyrosine kinase inhibitor therapy of advance non-small cell lung cancer patients is an independent prognostic factor for progression-free survival (PFS) and overal survival (OS). METHODS: A total of 45 patients who had computed tomography images were retrospectively evaluated at the diagnosis and during the treatment period before progression occurs. RESULTS: During treatment 19 patients (42.2%) had skeletal muscle loss. Objective response rates in muscle loss group and muscle stable group were 36.8% and 73.0%, respectively (p<0.01). Median follow-up time was 18.9 months (14.8-32.1). Median PFS was 14.7 months (95% CI 12.1-17.3) in muscle stable group and 7.6 months (95% CI 6.7-8.5) in muscle loss group (p<0.01). Median OS was 18.3 months (95% CI 16.5-20.2) in muscle loss group while it was 30.1 months (95% CI 22.1-38.2) in muscle stable group (p<0.01). In multivariate analysis for both PFS and OS, skeletal muscle loss was an independent prognostic factor. Hazard ratios (HR) for PFS and OS were 12.2 (95% CI 4.3-34.4) and 3.51 (95% CI 1.41-8.73) respectively. CONCLUSION: On CT imaging skeletal muscle loss before progression is an independent prognostic factor for both PFS and OS in advance non-small cell lung cancer patients who received EGFR tyrosine kinase inhibitor therapy.

PURPOSE: This study aimed to reveal the relationship between the level of galectin-3 expression and the depth of response to neoadjuvant therapy in bladder tumor tissue with muscle invasion revealed by transurethral biopsy. METHODS: The percentage of galectin-3 staining in transurethral biopsy tissue with muscle invasion was determined by immunohistochemistry. The patients were divided into two groups: the down-staging (+) group consisting of patients with pathological complete response or non-invasive bladder cancer, and the down-staging (-) group consisting of patients with stage 2 and above. RESULTS: There were 11 patients in the down-staging (+) group and 12 patients in the down-staging (-) group. There was no significant difference between the two groups in terms of median age, gender, smoking, clinical stage at the time of diagnosis, distribution of carboplatin or cisplatin used as a platinum agent. Galectin-3 was positive in 2 patients (18.2%) in the group where down-staging was achieved with neoadjuvant therapy, while it was positive in 9 patients (75%) in the other group (p = 0.01). The median follow-up period of the patients was 31.6 months (95% CI 25.1-39.3). Overall survival was 43.4 months in the down-staging (+) group (95% CI 25.1-61.6) and 31.6 months in the down-staging (-) group (95% CI 12.7-50.6). Although there was a numerical difference, it did not reach statistical significance (p=0.37). CONCLUSION: The rate of down-staging after platinum-based neoadjuvant chemotherapy is significantly higher in patients with low galectin-3 staining in transurethral bladder biopsy tissue.

PURPOSE: After failure of the first-line sorafenib treatment in advanced or metastatic stage hepatocellular carcinoma (HCC), regorafenib is one of the newly-approved targeted agents. We aimed to evaluate the efficacy of regorafenib in patients with advanced HCC treated in the second- or third-line setting. METHODS: In this retrospective and multicenter study, advanced HCC patients not eligible for local therapies, who received a second- or third-line regorafenib therapy after progression on the first-line sorafenib or sequential therapy with chemotherapy (CT) followed by sorafenib, were included. RESULTS: In the first-line setting, 28 (28.9%) patients received CT and 69 (71.1%) patients received sorafenib. There were 24 (24.7%) patients who were intolerant to sorafenib. Disease control rate (DCR) was 53.6% for all patients treated with regorafenib, 62.3% in patients who received regorafenib in the second-line, and 32.1% for those receiving regorafenib in the third-line (p=0.007). Median progression-free survival (PFS) and overall survival (OS) were 5.6 (range; 4.3-6.9) and 8.8 (range, 6.3-11.3) months for all patients treated with regorafenib vs. 7.1 months and 10.3 months for patients who received regorafenib in the second-line vs. 5.1 and 8.7 months for patients who received regorafenib in the third-line, respectively; however, there was no statistically significant difference (pPFS=0.22 and pOS=0.85). CONCLUSION: Although receiving CT as a first-line therapy in advanced HCC patients did not affect the survival rates of subsequent regorafenib therapy, it might diminish the DCR of regorafenib.

PURPOSE: 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) combined with computed tomography (CT) scan is accepted as a standard tool in the staging of oesophageal cancer (OC). Histological subtype of tumour is known to be a major determinant of prognosis and metabolic behaviour. In this study, we aimed to evaluate the effect of histological subtypes of OC on standard uptake value (SUVmax), metabolic tumour volume (MTV), and total lesion glycolysis (TLG) obtained by PET/CT, and also to compare this effect with prognosis. MATERIAL AND METHODS: Images and clinical course data of 57 patients who were diagnosed with EC and treated in our hospital between 2009 and 2016 were evaluated in a retrospective manner. PET/CT images were re-analysed in terms of metabolic parameters, and observations were compared with histological subtypes. RESULTS: No significant difference was observed between histological subtypes with SUVmax, overall survival (OS), or progression-free survival (PFS). Thus, MTV was observed to be related with histological subtype; MTV values of adenocancer patients were significantly higher than those of squamous cell cancer patients. CONCLUSIONS: Metabolic tumour volume was related with histological subtype of OC, but clinical staging, TLG, and SUVmax values were not related with histological subtype, which may suggest the use of MTV as a routine parameter for OC and inclusion of MTV observations in prognostic scoring.
RESUMEN
OBJECTIVES: Contrast nephropathy risk has been increasing in cancer patients. Nephrotoxic side effects of anti-vascular endothelial growth factor/receptor (anti-VEGF/R) drugs used in oncologic treatment are also prominent. The purpose of this study was to identify the possible association among anti-VEGF/R drugs use and development of the contrast-induced nephropathy (CIN) in patients with cancers. METHODS: A total of 92 patients were included in this prospective cross-sectional study. Patients whose glomerular filtration rate (GFR) of < 50 ml/min, hemoglobin of < 10 g/dl, and eastern cooperative oncology group (ECOG) score of ≥ 2 and had received nephrotoxic drugs were not included in the study. Blood samples were collected baseline at pre computed tomography (CT) and day 2, day 3 and day 7 later CT imaging. CIN was defined as either an increased serum creatinine value of 0.5 mg/dl or increased 25% to baseline. CIN frequency between groups receivingand not receiving anti-VEGF/R was compared using the chi-squared test. CIN frequency between bevacizumab and other anti-VEGF/R was also analyzed. RESULTS: There were 39 patients in the anti-VEGF/R (+) group and 53 patients in the anti-VEGF/R (-) group. Eleven patients (28%) in the anti-VEGF/R (+) group and 3 patients (5.6%) in the anti-VEGF/R (-) group had CIN (p = 0.006). In the anti-VEGF/R (+) group, 23 patients received bevacizumab (combined with FOLFOX/FOLFIRI), while 16 patients received other anti-VEGF/R (sunitinib, axitinib, regorafenib, aflibercept) effective treatments. CIN ratio in patients who received bevacizumab or other anti-VEGFR therapy was similar (p = 0 = 50). Of the patients, one patient had acute kidney injury leading to death. CONCLUSION: CIN was significantly more frequent in cancer patients who receiving anti-VEGF/R drugs than those not receiving anti-VEGF/R drugs.
