The Use of Herbal Medicine and Dietary Supplements in Cancer Patients Receiving Immune Checkpoint Inhibitors: A Multicenter Cross-Sectional Study.

AIMS: This study aimed to assess the habits and knowledge of cancer patients regarding the use of herbal medicines and dietary supplements in cancer patients receiving immune checkpoint inhibitors (ICI). METHODS: The data of 181 cancer patients who were over 18 years old and received ICIs were collected. The usage patterns, anticipated benefits and harms, and sources of supply were evaluated by filling researcher-prepared forms. RESULTS: Most patients did not use any kind of herbal medicine (91.2%) or dietary supplements (75.9%) during their immunotherapy. Boosting the immune system is the primary motivation for use among users. Multivitamins are the most frequently used supplements. Family members and TV advertisements were the main sources of information, in addition to limited advice from healthcare professionals. A minority of participants reported gastrointestinal side effects. Herbal medicine and dietary supplement use were more prevalent among patients with stage IV cancer and renal cell carcinoma (RCC). DISCUSSION: This study revealed that the limited uptake of herbal medicines and dietary supplements alongside ICI treatment among cancer patients. The lack of adequate information from healthcare professionals poses potential risks to patients. Improved communication with patients, education regarding herbal medicine and dietary supplement use, potential interactions, and associated risks during ICI treatment are essential. Further research is needed to identify the specific needs of patients, anticipated benefits, and potential harms of herbal medicine and dietary supplement use, together with ICIs.

Malnutrition and Related Factors in Older Patients With Gastrointestinal Cancer Receiving Chemotherapy.

Objectives The incidence and mortality of gastrointestinal (GI) malignancies increase exponentially with age. Malnutrition is a documented poor prognostic factor in older patients with cancer. There is insufficient data about the prevalence of malnutrition and associated factors in older patients with GI cancer. Thus, we aimed to investigate the prevalence of malnutrition and related factors among older patients with GI cancer. Methods A total of 121 patients aged over 70 years diagnosed with various types of GI cancers applied to the medical oncology clinic included in this cross-sectional study. We evaluated the nutrition status with a mini-nutritional assessment (MNA) score. Results The prevalence of malnutrition was 76 (62.8%) in our study population. The mean age was 76.5 (range 70 to 90 years), and 71 (58.6%) were male. In the multivariate logistic regression model, lower BMI (OR: 3.379, 95% CI: 1.465-7.812, p = 0.005), having gastroesophageal cancer (OR: 5.797, 95% CI: 2.387-14.091, p<0.001), treating with palliative chemotherapy (OR: 4.597, 95% CI: 1.799-11.772, p = 0.002), and frailty according to G8 score (OR: 10.798, 95% CI: 4.495-25.924, p<0.001) were associated with malnutrition. Conclusions Our study revealed that palliative chemotherapy, low BMI, frailty, and gastroesophageal cancer are risk factors for malnutrition in older patients with GI cancer. Physicians need to be aware of patients who may be at risk for malnutrition. Patients at risk of malnutrition may benefit from interventions to enhance their nutrition. Further studies consisting of larger cohorts are needed to determine malnutrition and related factors in older patients with cancer.

Geriatric nutritional risk index and controller nutritional status score before metastatic first-line chemotherapy predict survival in patients over 70 years of age with metastatic bladder cancer.

Introduction: Several prognostic factors have been identified in patients with metastatic bladder cancer (BC). As it is known, older adult patients are prone to nutritional deficiency. The knowledge about nutrition and impact on survival in older patients with metastatic bladder cancer is missing. It is necessary to specifically examine this population. Because timely interventions can make a positive impact on this patients population. This retrospective study aimed to evaluate the prognostic effect of the Geriatric Nutritional Risk Index (GNRI), Controller Nutritional Status (CONUT) score and Prognostic Nutritional Index (PNI) before first-line chemotherapy in the metastatic stage in patients with metastatic bladder cancer over 70. Participants and methods: Patients over 70 with pathologically confirmed denovo metastatic or recurrent metastatic bladder cancer were included in the study. Patients with infections diagnosed at the time of diagnosis, autoimmune diseases or history of steroid use were excluded. Since our population consists of a specific age group with a specific cancer, we found a new cut-off value by performing ROC analysis to ensure optimal sensitivity and specificity in terms of progression. Low GNRI value was related with poor nutritional status. Low PNI value was related with poor nutritional status and high CONUT score was related with poor nutritional status. Factors predicting overall survival (OS) and Progression-Free Survival (PFS) were assessed using both univariate and multivariate Cox proportional hazards analyses. Results: 106 patients were included in the study and the average age was 75.5 years. In the GNRI-Low group, PFS was significantly shorter than that in the GNRI-High group [HR (95% CI) = 57.1 (12.8-255.5), (p < 0.001)]. Among those with a low-CONUT score, PFS was found to be longer than that in the high-CONUT group [HR (95% CI) = 1.7 (1.0-3.0), (p = 0.039)]. The median PFS of the PNI-Low group wasn't significantly shorter than that of the PNI-High group [HR (95% CI) = 1.8 (0.5-6.2), (p = 0.359)]. Conclusion: Our study suggests that the GNRI and CONUT scores are useful for predicting survival in patients over 70 years of age with BC.

The prognostic factors in patients with advanced hepatocellular carcinoma: impact of treatment sequencing.

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.

Comparing the efficacy of regorafenib and 5-fluorouracil-based rechallenge chemotherapy in the third-line treatment of metastatic colorectal cancer.

BACKGROUND: The optimal treatment for metastatic colorectal cancer (mCRC) after the second line is still controversial. Regorafenib has been the standard of care in this setting as it improved overall survival (OS) compared to placebo. In real-world practice chemotherapy rechallenge is also a preferred option even though supporting evidence is not enough. We aim to compare the efficacy of regorafenib and 5-fluorouracil-based (5-FU) rechallenge treatment in the third line setting of mCRC. METHODS: In this retrospective multi-institutional trial, mCRC patients from 21 oncology centers who progressed after 2 lines of chemotherapy were analyzed. Patients who were treated with regorafenib or rechallenge therapy in the third-line setting were eligible. Rechallenge chemotherapy was identified as the re-use of the 5-FU based regimen which was administered in one of the previous treatment lines. OS, disease control rate (DCR), progression free survival (PFS) and toxicity were analyzed. RESULTS: Three hundred ninety-four mCRC patients were included in the study. 128 (32.5%) were in the rechallenge, and 266 (67.5%) were in the regorafenib group. Median PFS was 5.82 months in rechallenge and 4 months in regorafenib arms (hazard ratio:1.45,95% CI, p = 0.167). DCR was higher in the rechallenge group than regorafenib (77% vs 49.5%, respectively, p = < 0.001). Median OS after the third-line treatment was 11.99 (95% CI, 9.49-14.49) and 8.08 months (95% CI, 6.88-9.29) for rechallenge and regorafenib groups, respectively (hazard ratio:1.51, 95% CI, p < 0.001). More adverse effects and discontinuation were seen with regorafenib treatment. CONCLUSION: Our study revealed that higher disease control and OS rates were achieved with rechallenge treatment compared to regorafenib, especially in patients who achieved disease control in one of the first two lines of therapy.

Immune checkpoint inhibitor-related hearing loss: a systematic review and analysis of individual patient data.

PURPOSE: Immune checkpoint inhibitors (ICIs) are related to various immune-related adverse events (irAEs). However, the knowledge is limited with rare irAEs like hearing loss. Therefore, we evaluated the characteristics, presentation, and treatment of ICI-related hearing loss by reviewing the individual patient data from the previous studies. METHODS: We conducted a systematic search of the Web of Science, PubMed, and Embase databases for studies published until 17 November 2022. The selected MeSH search terms were "hearing loss" OR "hearing impairment" OR "ototoxicity" OR "vestibular toxicity" OR "audiovestibular toxicity" AND "immune checkpoint inhibitor" OR "immunotherapy." RESULTS: A total of 38 patients were included. Melanoma was the most frequent diagnosis (73.7%). The median time from ICI initiation to hearing loss development was 3 months. The hearing impairment was secondary to bilateral sensorineural hearing loss (SNHL) in 24 (68.6%) patients, and at least one other irAE accompanied the hearing loss in 24 patients. Hearing loss significantly improved in 45.7% of the patients. The overall response rate and disease control rate were 67.6% and 85.3%, respectively. CONCLUSION: We observed that most cases of ICI-related hearing loss were reversible, observed in patients with melanoma, accompanied by other irAEs, and associated with a high response rate to ICIs. With the expanded use of ICIs in the earlier treatment lines and adjuvant settings, the number of survivors with ICI-related hearing loss is expected to increase. Further research is needed to define the true prevalence of ICI-related hearing loss, optimal diagnosis, and management.

The risk of malnutrition and its clinical implications in older patients with cancer.

AIM: Malnutrition is a common geriatric syndrome with multiple negative outcomes including mortality. However, there is a scarcity of literature that focuses on the relationship between malnutrition risk and its clinical implications on geriatric syndromes and mortality among cancer patients. The aim of this study is to determine the clinical importance of malnutrition risk in geriatric oncology practice. METHOD: 180 patients with cancer who were ≥ 65 years were included in the study. All patients were questioned in terms of geriatric syndromes, including polypharmacy, frailty, probable sarcopenia, fall risk, dynapenia, depression, cognitive impairment, insomnia, and excessive daytime sleepiness. Mini Nutritional Assessment scores > 23.5 and 17-23.5 were categorized as well-nourished and malnutrition risk, respectively. RESULTS: Of the 180 patients (mean age 73.0 ± 5.6 years, female: 50%), the prevalence of malnutrition risk was 28.9%. There was no statistically significant difference between the groups in terms of age, gender, education, marital status, body mass index, and comorbidities except for chronic obstructive pulmonary disease (p > 0.05). After adjustment for age, sex, and body mass index; polypharmacy (odds ratio [OR]: 3.17; 95% confidence interval [CI], 1.48-6.81), reduced calf circumference (OR: 3.72; 95% CI, 1.22-11.38), fall risk (OR: 2.72; 95% CI, 1.03-7.23), depression (OR: 6.24; 95% CI, 2.75-14.18), insomnia (OR: 4.89; 95% CI, 2.16-11.05), and frailty (OR: 2.44; 95% CI, 1.75-3.40) were associated with malnutrition risk compared to well-nourished patients (p < 0.05). Median survival in patients with malnutrition risk was 21.3 months (range 14.1-28.4 95% CI) and median survival in patients who were defined as well nourished was not reached (p < 0.001). CONCLUSION: The risk of malnutrition was associated with a higher risk for all-cause mortality in older patients with cancer, and was associated with many geriatric syndromes, including polypharmacy, fall risk, frailty, insomnia, and depression.

The Effect of HER2-Low Status on Pathological Complete Response and Survival in Triple-Negative Breast Cancer: A Systemic Review and Meta-Analysis.

This meta-analysis conducted a comprehensive analysis of research investigating the correlation between HER2 expression levels and treatment outcomes in early-stage triple-negative breast cancer (TNBC) patients. We systematically searched major databases for studies published up to January 01, 2023. The data from various studies examined the relationship between HER2-zero and HER2-low tumors in terms of pathological complete response (pCR) rates, disease-free survival (DFS), and overall survival (OS) outcomes. The odds ratio (OR) and 95% confidence interval (CI) by the number of events were calculated using the Mantel-Haenszel method to analyze pCR. The hazard ratio and 95% CI were calculated using the inverse variance method for DFS and OS. In all comparisons, I2 was 0% and no heterogeneity was detected. A total of 12 retrospective studies involving 4094 patients were included. Thirty-six percent of the patients were in the HER2-low group. All 12 studies were included in the pooled analysis for pCR, and there was no difference between HER2-zero and HER2-low (40% vs. 38%, respectively; pooled OR:1.01 95% CI 0.88-1.16; I2: 0%). Four studies were included in the pooled analysis for DFS and 3 in the OS analysis. DFS and OS were significantly better in the HER2-low group (pooled hazard ratio: 0.67 for DFS, 0.64 for OS). There was no difference between HER2-low and HER2-zero in terms of pCR in early-stage TNBC. However, HER2-low was found to be associated with prolonged DFS and OS.

Recommendations of the International Society of Geriatric Oncology on skin cancer management in older patients.

INTRODUCTION: Non-melanoma skin cancer (NMSC) is becoming ever more prevalent among older adults. However, older adults with NMSC are often underrepresented in clinical trials and guidelines on effective management is still unclear. The International Society of Geriatric Oncology (SIOG) created a multi-disciplinary task force to explore the potential in developing practical guidelines for the treatment of older patients with basal cell carcinoma (BCC) and skin (cutaneous) squamous cell carcinoma (cSCC). MATERIALS AND METHODS: A systematic literature search to identify relevant and up-to-date literature on treatment of NMSC in older adults was conducted on various databases including MEDLINE, Embase, CINAHL, Cochrane, and PubMed. The resulting papers were discussed by an expert panel, leading to a consensus recommendation. RESULTS: A total of 154 articles were identified for the expert panel to utilise in generating consensus recommendations. A major focus on geriatric assessment and management options including surgery, radiotherapy, systemic therapy, clinical monitoring, and medical/medicophysical therapy were reviewed for recommendations. DISCUSSION: Patient age should not be the sole deciding factor in the management of patients with NMSC. Assessment from a multidisciplinary team (MDT) is crucial, and the decision-making process should consider the patient's lifestyle, needs, and expectations. A comprehensive geriatric assessment should also be considered. Patients should feel empowered to advocate for themselves and have their views considered a part of the MDT discussion.

Major and minor salivary gland cancers: A multicenter retrospective study.

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.

Efficacy and safety of concomitant chemo-endocrine therapy in neoadjuvant treatment of hormone-positive HER2-negative breast cancer: a systemic review and meta-analysis.

BACKGROUND: The rate of pathological complete response (pCR) with both chemotherapy alone (CT) and endocrine therapy (ET) in the neoadjuvant (Na) treatment of hormone receptor (HR)-positive/HER2-negative breast cancer (BC) is unsatisfactory. Limited data on neoadjuvant concomitant chemotherapy and endocrine therapy (NaCET) are available. RESEARCH DESIGN AND METHODS: In this meta-analysis analyzed the efficacy and safety of randomized controlled trials (RCT) comparing the use of NaCET in HR-positive/HER2-negative BC. A comprehensive search was performed on PubMed, Cochrane Library and EMBASE databases, and congress paper lists for studies published/presented until 1 December 2022. RESULTS: Five RCTs involving a total of 630 patients were included. A pooled analysis of the five studies demonstrated that the pCR ratio was numerically higher in the NaCET arm than in the NaCT arm, but the difference was not statistically significant (6.5% vs. 3.8%; OR:1.72, 95% CI 0.82-3.62). Nonetheless, the NaCET arm exhibited a significantly higher objective response rate (ORR) (82% vs. 72.7%; OR:1.77, 95% CI 1.20-2.62). There was no difference between the arms in terms of grade 3-5 adverse events. CONCLUSIONS: In HR-positive/HER2-negative BC, NaCET significantly increases ORR without an increase in serious adverse events. Although the pCR rate increased numerically, it was not statistically significant.

Adoptive Cell Therapy in Hepatocellular Carcinoma: A Review of Clinical Trials.

Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer. Immune checkpoint inhibitors (ICIs) have become the new reference standard in first-line HCC treatment, replacing tyrosine kinase inhibitors (TKIs) such as sorafenib. Many clinical trials with different combinations are already in development to validate novel immunotherapies for the treatment of patients with HCC. Adoptive cell therapy (ACT), also known as cellular immunotherapy, with chimeric antigen receptors (CAR) or gene-modified T cells expressing novel T cell receptors (TCR) may represent a promising alternative approach to modify the immune system to recognize tumor cells with better clinical outcomes. In this review, we briefly discuss the overview of ACT as a promising treatment modality in HCC, along with recent updates of ongoing clinical trials.

Comparison of HER2-zero and HER2-low in terms of clinicopathological factors and survival in early-stage breast cancer: A systematic review and meta-analysis.

BACKGROUND: The prognostic differences between HER2-zero and HER2-low breast cancer (BC) remain unclear. Purpose of this meta-analysis is to investigate the differences between HER2-low and HER2-zero in terms of clinicopathological factors and survival outcomes in early-stage BC. METHODS: We searched major databases and congress proceedings until November 1, 2022 to identify studies comparing HER2-zero and HER2-low in early-stage BC. HER2-zero immunohistochemically (IHC) was defined as score 0, while HER2-low was defined as IHC 1+ or 2+/in situ hybridization negative. RESULT: A total of 23 retrospective studies involving 636,535 patients were included. HER2-low rate was 67.5% in the hormone receptor (HR)-positive group, while this rate was 48.6% in the HR-negative group. In the analysis of clinicopathological factors by HR status, the proportion of premenopausal patients within the HR-positive group was greater in the HER2-zero arm (66.5% vs 61.8%), whereas grade 3 tumors (74.2% vs 71.5%), patients younger than 50 years of age (47.3% vs 39.6%), and T3-T4 tumors (7.7% vs 6.3%) within the HR-negative group was higher in the HER2-zero arm. In both the HR-positive and HR-negative groups, the HER2-low arm showed significantly improved results for disease-free survival (DFS) and overall survival (OS). The hazard ratios for DFS and OS in the HR-positive group were 0.88 (95% CI 0.83-0.94) and 0.87 (95% CI 0.78-0.96), respectively. In the HR-negative group, the hazard ratios for DFS and OS were 0.87 (95% CI 0.79-0.97) and 0.86 (95% CI 0.84-0.89), respectively. CONCLUSION: In early-stage BC, HER2-low is associated with better DFS and OS compared to HER2-zero, regardless of HR status.

Efficacy of subsequent treatments in patients with hormone-positive advanced breast cancer who had disease progression under CDK 4/6 inhibitor therapy.

BACKGROUND: There is no standard treatment recommended at category 1 level in international guidelines for subsequent therapy after cyclin-dependent kinase 4/6 inhibitor (CDK4/6) based therapy. We aimed to evaluate which subsequent treatment oncologists prefer in patients with disease progression under CDKi. In addition, we aimed to show the effectiveness of systemic treatments after CDKi and whether there is a survival difference between hormonal treatments (monotherapy vs. mTOR-based). METHODS: A total of 609 patients from 53 centers were included in the study. Progression-free-survivals (PFS) of subsequent treatments (chemotherapy (CT, n:434) or endocrine therapy (ET, n:175)) after CDKi were calculated. Patients were evaluated in three groups as those who received CDKi in first-line (group A, n:202), second-line (group B, n: 153) and ≥ 3rd-line (group C, n: 254). PFS was compared according to the use of ET and CT. In addition, ET was compared as monotherapy versus everolimus-based combination therapy. RESULTS: The median duration of CDKi in the ET arms of Group A, B, and C was 17.0, 11.0, and 8.5 months in respectively; it was 9.0, 7.0, and 5.0 months in the CT arm. Median PFS after CDKi was 9.5 (5.0-14.0) months in the ET arm of group A, and 5.3 (3.9-6.8) months in the CT arm (p = 0.073). It was 6.7 (5.8-7.7) months in the ET arm of group B, and 5.7 (4.6-6.7) months in the CT arm (p = 0.311). It was 5.3 (2.5-8.0) months in the ET arm of group C and 4.0 (3.5-4.6) months in the CT arm (p = 0.434). Patients who received ET after CDKi were compared as those who received everolimus-based combination therapy versus those who received monotherapy ET: the median PFS in group A, B, and C was 11.0 vs. 5.9 (p = 0.047), 6.7 vs. 5.0 (p = 0.164), 6.7 vs. 3.9 (p = 0.763) months. CONCLUSION: Physicians preferred CT rather than ET in patients with early progression under CDKi. It has been shown that subsequent ET after CDKi can be as effective as CT. It was also observed that better PFS could be achieved with the subsequent everolimus-based treatments after first-line CDKi compared to monotherapy ET.

Association of Serum Hepatocyte Growth Factor Level with Systemic Inflammatory Biomarkers in Patients with Pancreatobiliary Cancer.

BACKGROUND: Hepatocyte growth factor is a cytokine secreted by the stromal cells in the tumor microenvironment. There is little information about the clinical significance of serum hepatocyte growth factor level in patients diagnosed with pancreatobiliary cancer. The objective of the current study was to investigate the relationship between serum hepatocyte growth factor level with inflammation markers and the clinical features of patients with pancreatobiliary cancer. METHODS: A total of 62 patients with pancreatobiliary cancer were included in this study. Serum hepatocyte growth factor concentrations were evaluated utilizing the enzyme-linked immunosorbent assay method. RESULTS: The median serum hepatocyte growth factor level was 329.1 ng/mL (1.4-1051.1). The patients were categorized into 2 groups as those below the median hepatocyte growth factor level (low hepatocyte growth factor) and those above the median hepatocyte growth factor level (high hepatocyte growth factor). While 40.9% of the patients without metastasis were observed to be in the high hepatocyte growth factor group, 72.2% of the metastatic patients were observed to be in the high hepatocyte growth factor group (P = .025). The median levels of monocyte, monocyte-to-lymphocyte ratio, C-reactive protein, and C-reactive protein-to-albumin ratio were found to be significantly higher in the high hepatocyte growth factor group as compared to the low hepatocyte growth factor group (P < .050). CONCLUSION: The significant relationship between serum hepatocyte growth factor level and systemic inflammation markers in patients with pancreatobiliary cancer is shown for the first time in our study. This study, which showed a significant relationship between the presence of metastasis and serum hepatocyte growth factor level, suggests that serum hepatocyte growth factor level may be a prognostic biomarker in patients who are diagnosed with pancreatobiliary cancer.

Real-life experience of patients with sarcomatoid renal cell carcinoma: a multicenter retrospective study.

Sarcomatoid renal cell carcinoma (sRCC) is a rare variant of renal cell carcinoma (RCC) and is associated with a poor prognosis. We reviewed the outcomes of patients from oncology centers in Turkey. Our aim is to share our real-life experience and to contribute to the literature. The demographic and clinical features, treatment, and survival outcomes of 148 patients with sRCC were analyzed. The median age at the time of diagnosis was 58 years (range: 19-83 years). Most patients (62.8%) had clear-cell histology. Most patients were in the intermediate Memorial Sloan-Kettering Cancer Center (MSKCC) risk group (67.6%) and were stage 4 at the time of diagnosis (63.5%). The most common sites of metastasis were the lung (60.1%), lymph nodes (47.3%), and bone (35.8%). The patients received a median of two lines (range: 0-6) of treatment. The most common side effects were fatigue, hematological side effects, hypertension, and hypothyroidism. The median follow-up was 20.9 months (range: 1-162 months). The median overall survival (OS) was 30.8 months (95% confidence interval: 24.9-36.7 months). In multivariate analysis, high MSKCC scores, sarcomatoid differentiation rates >50%, having stage 4 disease, and having lung metastasis at the time of diagnosis were independent factors for poor prognosis affecting OS. No difference was observed between patients who received tyrosine kinase inhibitor (TKI) as the first or second-line treatments. Similarly, no difference between TKI and immunotherapy as the second-line treatment. In conclusion, sRCC is a rare variant of RCC with a poor prognosis and response to treatment. Larger-scale prospective studies are needed to define an optimal treatment approach for longer survival in this aggressive variant.

The impact of adjuvant oxaliplatin and tumor sidedness on the overall survival of stage IIB colon cancer patients: a multicentre study.

The aim of this multicentre retrospective study was to compare the efficacy of adjuvant chemotherapy regimens both with and without oxaliplatin and tumor sidedness in stage IIB (pT4aN0) colon cancer patients. This study included patients with stage IIB colon cancer who underwent curative surgery and received adjuvant chemotherapy. The patients were divided into two groups (one with and one without oxaliplatin) to compare the overall survival (OS) in right- and left-sided tumors. The study population included 298 patients with stage IIB colon cancer (median age: 57) of whom 69.1% were male. Forty-four per cent of these patients (n = 131) were diagnosed with right-sided colon cancer. The median follow-up duration was 35.9 months. In the entire population, a median OS was not reached, and the five-year OS was 83%. The median disease-free survival (DFS) was 12 months. There was no significant difference in terms of the five-year OS between right- (82%) and left-sided (84%) colon tumors (p = 0.67). In addition, the five-year OS of patients treated with and without oxaliplatin were 76% and 89%, respectively, and there was no statistically significant difference (p = 0.23). The five-year OS of the patients treated with and without oxaliplatin were 83% and 96.5%, respectively, (p = 0.8) in right-sided colon tumors, while it was 75% and 93% (p = 0.06), respectively, in left-sided colon tumors. Tumor sidedness and the addition of oxaliplatin to adjuvant chemotherapy were not found to be associated with the OS in stage IIB colon cancer patients in our study. Further large prospective studies that also include MSI, RAS and BRAF status data are warranted in colon cancer patients.
