RESUMO
Background: Low serum sodium affects cancer prognosis, but its impact on immunotherapy is unclear. Objective: Assessing the association of pre- and post-ICI treatment sodium levels with survival. Methods: We retrospectively analyzed patients receiving ICI in January 2012-December 2023, collecting serum sodium levels at treatment initiation and 4 weeks post-ICI, with overall survival (OS) as the primary outcome. Results: Low sodium was observed in 125 and 119 patients pre-and post-treatment respectively. Pre-ICI and post-ICI low sodium correlated with decreased OS [10.6 vs. 22.9 months (p = 0.001) and 11.6 vs. 27.2 months (p = 0.009)]. Multivariate analysis identified pre-ICI low sodium [HR: 1.685; 95% CI: 1.050-2.705; p = 0.031] as an independent risk factor for worse OS. Conclusion: Low baseline serum sodium was an independent risk factor for poor OS in patients treated with ICIs.
This study explored how sodium levels impact cancer patients' outcomes during treatment with immune checkpoint inhibitors (ICIs). We examined sodium levels before and after ICI treatment in patients with cancer. Low sodium levels both before and after treatment were associated with poorer outcomes. Specifically, patients with low sodium levels before treatment had shorter survival times compared to those with normal levels. Similarly, patients with low sodium levels after treatment had shorter survival times compared to those with normal levels. These findings suggest that low baseline sodium levels could indicate poorer outcomes in patients receiving ICIs.
RESUMO
INTRODUCTION: Adrenocortical carcinoma (ACC) is a rare yet highly malignant tumor associated with significant morbidity and mortality. This study aims to delineate the clinical features, survival patterns, and treatment modalities of ACC, providing insights into the disease's prognosis. MATERIALS AND METHODS: A retrospective analysis of 157 ACC patients was performed to assess treatment methodologies, demographic patterns, pathological and clinical attributes, and laboratory results. The data were extracted from the hospital's database. Survival analyses were conducted using the Kaplan-Meier method, with univariate and multivariate analyses being performed through the log-rank test and Cox regression analyses. RESULTS: The median age was 45, and 89.4% had symptoms at the time of diagnosis. The median tumor size was 12 cm. A total of 117 (79.6%) patients underwent surgery. A positive surgical border was detected in 26 (24.1%) patients. Adjuvant therapy was administered to 44.4% of patients. The median overall survival for the entire cohort was 44.3 months. Median OS was found to be 87.3 months (95% confidence interval [CI] 74.4-100.2) in stage 2, 25.8 (95% CI 6.5-45.1) months in stage 3, and 13.3 (95% CI 7.0-19.6) months in stage 4 disease. Cox regression analysis identified age, Ki67 value, Eastern Cooperative Oncology Group performance status, and hormonal activity as significant factors associated with survival in patients with nonmetastatic disease. In metastatic disease, only patients who underwent surgery exhibited significantly improved overall survival in univariate analyses. CONCLUSION: ACC is an uncommon tumor with a generally poor prognosis. Understanding the defining prognostic factors in both localized and metastatic diseases is vital. This study underscores age, Ki67 value, Eastern Cooperative Oncology Group performance status, and hormonal activity as key prognostic determinants for localized disease, offering critical insights into the complexities of ACC management and potential avenues for targeted therapeutic interventions.

BACKGROUND: Poly (ADP-ribose) polymerase inhibitors (PARPi) have been associated with thrombotic events, although the association with thrombosis risk in different cancers remains poorly defined. METHODS: This meta-analysis included phase II and phase III clinical trials in which patients with metastatic prostate cancer were treated with PARPi either as monotherapy or in combination. The primary endpoints were the rates of thromboembolic events in prostate cancer patients. RESULTS: A total of 2210 and 1662 patients with prostate cancer were compared in the PARP inhibitor and control groups, respectively. 96 (4.3â¯%) and 37 (2.2â¯%) patients had thrombosis in the PARPi and control groups, respectively. PARPi had a statistically significant increased risk of thrombosis in prostate cancer patients (Odds Ratio (OR)=1.98, 95â¯% CI: 1.06-3.70, P=0.030). CONCLUSION: The heightened thrombotic risk associated with PARPi treatment in prostate cancer emphasizes the need for comprehensive management protocols to effectively reduce the risk and ensure safer outcomes.

Metastatic castration-resistant prostate cancer (mCRPC) remains a challenging condition to treat despite recent advancements. This retrospective study aimed to assess the activity and tolerability of Lutetium-177 (Lu-177) PSMA-617 radioligand therapy (RLT) in mCRPC patients across multiple cancer centers in Turkey. The study included 165 patients who received at least one cycle of Lu-177 PSMA-617 RLT, with the majority having bone metastases and undergone prior treatments. Prostate-specific antigen (PSA) levels were assessed before each treatment cycle, and the biochemical response was evaluated in accordance with the Prostate Cancer Work Group 3 Criteria. The PSA decline of ≥50% was classified as a response, while an increase of ≥25% in PSA levels was indicative of progressive disease. Neither response nor progression was considered as stable disease. The Lu-177 PSMA-617 RLT led to a significant PSA response, with 50.6% of patients achieving a >50% decrease in PSA levels. Median overall survival (OS) and progression-free survival were 13.5 and 8.2 months, respectively. Patients receiving Lu-177 PSMA-617 RLT in combination with androgen receptor pathway inhibitors (ARPIs) had a higher OS compared to those receiving Lu-177 PSMA-617 RLT alone (18.2 vs 12.3 months, P = .265). The treatment was generally well-tolerated, with manageable side effects such as anemia and thrombocytopenia. This study provides real-world evidence supporting the effectiveness and safety of Lu-177 PSMA-617 RLT in mCRPC patients, particularly when used in combination with ARPIs. These findings contribute to the growing body of evidence on the potential benefits of PSMA-targeted therapies in advanced prostate cancer.

Histamine and H1 receptors play a crucial role in the tumor microenvironment. Preclinical data showed that concomitant use of antihistamines and immune checkpoint inhibitors (ICIs) might increase the effect of ICIs. This study aimed to evaluate the impact of antihistamines on the oncological outcomes of ICIs. This retrospective study was conducted in a tertiary cancer center. Advanced cancer patients treated with ICIs were included in this study. A total of 133 patients receiving ICIs in the metastatic setting were included. Melanoma (33.1%) was the most common tumor type. The most common ICI was nivolumab (63.2%). Fifty-five (38.4%) patients received antihistamines concomitantly with ICIs. The most common antihistamine was pheniramine (85.5%). The median progression-free survival (PFS) (8.2 vs. 5.1 months, P â =â 0.016) and overall survival (OS) (16.2 vs. 7.7 months, P â =â 0.002) were longer in patients receiving antihistamines concomitantly with ICIs. In multivariate analysis, PFS [hazard ratio (HR)â =â 0.63, 95% CI: 0.40-0.98, P â =â 0.042] and OS (HRâ =â 0.49, 95% CI: 0.29-0.81, P â =â 0.006) were also better in those patients after adjusting for confounding factors, such as performance status, bone or liver metastasis, and concurrent chemotherapy. This study suggested that antihistamines may enhance the efficacy of ICIs in patients with advanced cancer. If validated in prospective trials, antihistamines and ICIs combinations might be new options to improve oncological outcomes.

INTRODUCTION: Immunotherapy (IO)-based combination therapies have emerged as the standard of care for first-line treatment of metastatic renal cell carcinoma (mRCC) among patients classified as intermediate and poor risk. However, in the favorable risk group, the available data remains less compelling. This study aims to assess and compare the effectiveness of IO-based combination therapies versus tyrosine kinase inhibitor (TKI) monotherapy in patients with favorable risk group according to the International mRCC Database Consortium (IMDC). METHODS: Recent update data from phase-III RCTs of IO-based combinations approved by the Food and Drug Administration were used. Studies that provided data on progression free survival (PFS) and overall survival (OS) of IMDC favorable risk were included in the analysis. RESULTS: A cohort of 1,088 patients categorized within the IMDC favorable risk group was enrolled for analysis. In comparison to sunitinib, the combination of immunotherapy (IO) and tyrosine kinase inhibitor (TKI) exhibited a reduction in the risk of disease progression (HR = 0.67, 95 % CI: 0.55-0.82; p < 0.001). Conversely, the combination of IO and IO displayed an elevated risk of disease progression (HR = 1.60, 95 % CI: 1.13-2.26; p = 0.008). However, neither the IO plus TKI (HR = 0.99, 95 % CI: 0.79-1.24; p = 0.92) nor IO plus IO (HR = 0.94, 95 % CI: 0.64-1.37; p = 0.75) combinations demonstrated a noteworthy improvement in overall survival (OS). Notably, within the IO plus TKI subgroup, combination therapy yielded a higher objective response rate (ORR) (OR = 0.40, 95 % CI: 0.28-0.57; p < 0.001). On the other hand, the IO plus IO combination displayed a lower ORR than sunitinib (OR = 2.54, 95 % CI: 1.51-4.27; p < 0.001). CONCLUSIONS: In the first-line treatment of IMDC favorable-risk mRCC, IO and TKI combinations show enhanced progression-free survival and response rate without improving overall survival. This emphasizes the demand for further exploration of combination therapies in this patient group.

Visceral metastasis (VM) and a higher number of bone metastasis generally define high volume/risk in patients with metastatic castration-sensitive prostate cancer (mCSPC). Subgroup analysis of pivotal trials did not show a clear benefit of second-generation non-steroidal anti-androgens (NSAAs) in patients with VM. However, subgroup analysis of the trial assessing abiraterone acetate, a CYP 17 inhibitor, plus prednisone (AAP) showed an improved overall survival (OS) in patients with mCSPC with VM. We searched MEDLINE, Web of Science, and congress abstracts for the phase III randomized controlled trials of second-generation NSAAs and AAP in patients with mCSPC. In this pooled analysis, we included 6485 patients from the 6 phase III trials. The rate of patients with VM was 15.2%. Interestingly, in contrast to NSAAs, AAP seems to be effective in improving OS among patients with VM (hazard ratio, HR: 0.89, 95% CI, 0.72-1.11, P = .30 for second-generation NSAAs; HR: 0.58, 95% CI, 0.40-0.84, P = .004 for AAP). In contrast, both second-generation NSAAs (HR: 0.63, 95% CI, 0.57-0.70, P < .001) and AAP (HR: 0.68, 95% CI, 0.57-0.81, P < .001) improved OS in patients without VM. In this pooled analysis, we demonstrate that while AAP provided an OS improvement in patients with VM, second-generation NSAAs did not demonstrate a similar OS benefit in this population.

AIM: Description of patient characteristics, effectiveness and safety in Turkish patients treated with pazopanib for metastatic soft tissue sarcoma (STS). PATIENTS AND METHODS: This multicenter study is based on retrospective review of hospital medical records of patients (≥ 18 years) treated with pazopanib for non-adipocytic metastatic STS at 37 Oncology clinics across Turkey. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS) and overall survival (OS) were evaluated with further analysis of data on the three most common histological subtypes (leiomyosarcoma [LMS], undifferentiated pleomorphic sarcoma [UPS], synovial sarcoma [SS]) in the cohort. RESULTS: Data of 552 adults (57.6% women, median age: 52 years) were analyzed. DCR and ORR were 43.1% and 30.8%, respectively. Median PFS was 6.7 months and OS was 13.8 months. For LMS, UPS and SS, median PFSs were 6.1, 5.9 and 7.53 months and median OSs were 15.03, 12.87 and 12.27 months, respectively. ECOG ≥ 2 was associated with poor PFS and OS. Liver metastasis was only a factor for progression. Second-line use of pazopanib (vs. front-line) was associated with better PFS, its use beyond third line predicted worse OS. Adverse events (AE) occurred in 82.7% of patients. Most common AEs were fatigue (58.3%) and anorexia (52.3%) which were graded as ≥ 3 in 8.2% and 7.4% of patients, respectively. CONCLUSION: Pazopanib is effective and well-tolerated in treatment of non-adipocytic metastatic STS. Its earlier use (at second-line), good performance status may result in better outcomes. Worldwide scientific collaborations are important to gain knowledge on rarer STS subtypes by conducting studies in larger patient populations.

INTRODUCTION: We aimed to evaluate clinical features, prognostic factors, and treatment preferences in patients with non-clear cell renal cell carcinoma (nccRCC). METHODS: Patients with metastatic nccRCC were selected from the Turkish Oncology Group Kidney Cancer Consortium (TKCC) database. Clinical features, prognostic factors, and overall survival (OS) outcomes were investigated. RESULTS: A total of 118 patients diagnosed with nccRCC were included in this study. The median age at diagnosis was 62 years (interquartile range: 56-69). Papillary (57.6%) and chromophobe tumors (12.7%) are common histologic subtypes. Sarcomatoid differentiation was present in 19.5% of all patients. When the patients were categorized according to the International Metastatic RCC Database Consortium (IMDC) risk scores, 66.9% of the patients were found to be in the intermediate or poor risk group. Approximately half of the patients (55.9%) received interferon in the first line. At the median follow-up of 53.2 months (95% confidence interval [CI]: 34.7-71.8), the median OS was 19.3 months (95% CI: 14.1-24.5). In multivariate analysis, lung metastasis (hazard ratio [HR]:2.22, 95% CI: 1.23-3.99) and IMDC risk score (HR: 2.35, 95% CI: 1.01-5.44 for intermediate risk; HR: 8.86, 95% CI: 3.47-22.61 for poor risk) were found to be independent prognostic factors. CONCLUSION: In this study, survival outcomes are consistent with previous studies. The IMDC risk score and lung metastasis are the independent prognostic factors for OS. This is an area that needs research to better treat this group of patients and create new treatment options.

OBJECTIVE: Treatment beyond progression (TBP) with immune checkpoint inhibitors (ICIs) is an evolving field due to the limitations of conventional imaging in response evaluation. However, real-life data on the benefit of TBP is scarce, especially from the limited resource settings and patients treated in the later lines. Therefore, we aimed to investigate the survival benefit of TBP with ICIs in patients with advanced tumors from a limited resource setting. METHODS: For this multi-center retrospective cohort study, we included 282 patients treated with ICIs and had radiological progression according to RECIST 1.1 criteria. We evaluated post-progression survival according to the use of TBP (TBP and non-TBP groups) with univariate and multivariate analyses. RESULTS: The cohort's median age was 61, and 84.4% were treated in the second or later lines. 82 (29.1%) of 282 patients continued on ICIs following the initial progression. In multivariate analyses, patients in the TBP group had improved post-progression survival compared to non-TBP (13.18 vs. 4.63 months, HR: 0.500, 95% CI: 0.349-0.717, p < 0.001). The benefit of the TBP was independent of the tumor type, treatment line, and age. Furthermore, TBP with ICIs remained associated with improved post-progression survival (HR: 0.600, 95% CI: 0.380-0.947, p = 0.028) after excluding the patients with no further treatment after progression in the non-TBP arm. CONCLUSIONS: In this study, we observed that patients receiving ICIs beyond progression had considerably longer survival. Continuation of ICIs after progression should be considered a reasonable management option for patients with advanced cancer, specifically for patients with limited alternative options.

Neoadjuvant chemotherapy (NACT) in gastroesophageal junction (GEJ) and gastric cancer (GC) was shown to improve survival in recent studies. We aimed to share our real-life experience of patients who received NACT to compare the efficacy and toxicity profile of different chemotherapy regimens in our country. This retrospective multicentre study included locally advanced GC and GEJ cancer patients who received NACT between 2007 and 2021. Relation between CT regimens and pathological evaluation were analysed. A total of 794 patients from 45 oncology centers in Turkey were included. Median age at the time of diagnosis was 60 (range: 18-86). Most frequent NACT regimens used were FLOT (65.4%), DCF (17.4%) and ECF (8.1%), respectively. In the total study group, pathological complete remission (pCR) rate was 7.2%, R0 resection rate 86.4%, and D2 dissection rate was 66.8%. Rate of pCR and near-CR (24%), and R0 resection (84%) were numerically higher in FLOT arm (p > 0.05). Patients who received FLOT had also higher chemotherapy-related toxicity rate compared to patients who received other regimens (p > 0.05). Median follow-up time was 16 months (range: 1-154 months). Estimated median overall survival (OS) was 58.4months (95% CI: 35.2-85.7) and disease-free survival (DFS) was 50.7 months (95% CI: 25.4-75.9). The highest 3-year estimated OS rate was also shown in FLOT arm (68%). We still do not know which NACT regimen is the best choice for daily practice. Clinicians should tailor treatment regimens according to patients' multifactorial status and comorbidities for to obtain best outcomes. Longer follow-up period needs to validate our results.

BACKGROUND: This study aims to assess the effect of primary tumour resection (PTR) on patients with metastatic colorectal cancer (mCRC) treated with cetuximab. METHODS: This retrospective cohort study was conducted in a tertiary cancer center in Turkey. Patients with mCRC between January 2009 and December 2020 were extracted from the electronic hospital management system. Patients with RAS wild-type synchronous metastatic left-sided colon or rectum cancer who had cetuximab-containing treatment protocol were included in the study. The primary outcomes were overall survival (OS) and progression-free survival (PFS). The secondary outcome was response rates. RESULTS: A total of 111 patients with mCRC were included in this study. PTR was performed in 57.7% of all patients. Fifty-nine (53.2%) and 52 (46.8%) patients had rectal and left colon tumours, respectively. The combination treatment with cetuximab was FOLFIRI in 62.2% and FOLFOX in 29.7% of all patients. In subgroup analysis, the median PFS was 7.9 and 9 months in PTR (+) and PTR (-) patients, respectively. The difference between the groups was not statistically significant (P = 0.3). The median OS was 33 months in all patients. In subgroup analysis, the median OS was 39 and 27.9 months in PTR (+) and PTR (-) patients, respectively. The difference between the groups was statistically significant (P = 0.002). After adjusting for confounding factors, PTR and ECOG performance score were the independent prognostic factors for OS. CONCLUSION: PTR improved the OS in patients with RAS wild-type synchronous left-sided colon or rectum cancer treated with cetuximab-containing chemotherapy regimens.

INTRODUCTION: Cyclin-dependent kinases 4 and 6 (CDK4/6) inhibitors are the new generation drugs that have been started to be used in our clinical practice recently. These drugs have been shown to have better progression-free survival compared to standard therapy in patients with hormone receptor-positive (HR) and human epidermal growth factor receptor 2 (HER-2)-negative breast cancer. The most common side effects of CDK 4-6 inhibitors are neutropenia, nausea, leukopenia, fatigue, and diarrhea. This case demonstrated vortex keratopathy in both eyes, a rare condition in patients with breast cancer treated with ribociclib. CASE REPORT: A 68-year-old female patient was diagnosed with locally advanced HR (+)/HER2 (-) breast cancer in March 2015. In June 2021, bone metastases were detected. The patient was started on ribociclib and fulvestrant. After three cycles of ribociclib and fulvestrant treatment, she was admitted with the complaint of blurred vision in her left eye. Slit-lamp biomicroscopy examination revealed subepithelial haze with central subepithelial whorls in both corneas, more in the left eye, and also a mild punctate epithelial staining was observed with the application of fluorescein dye. MANAGEMENT AND OUTCOME: Ribociclib treatment was immediately discontinued and no changes were observed in the cornea and vision levels during the one-month follow-up. DISCUSSION: Routine and regular follow-up eye examinations in breast cancer patients treated with ribociclib may benefit patients in our daily clinical practice and may help us to detect side effects at an early stage and to manage them more effectively.

BACKGROUND: A novel prognostic model was recommended for patients with metastatic RCC (mRCC) by the International mRCC Database Consortium (IMDC). In this study, we aimed to externally validate a novel risk model for the IMDC-favorable risk group in patients with mRCC. METHODS: The Turkish Oncology Group Kidney Cancer Consortium (TKCC) is a multicenter registry that includes 13 cancer centers in Turkey. As described by Schmidt et al., 3 parameters (ie, time from diagnosis to systemic therapy <3 vs. ≥3 years, Karnofsky Performance Status [KPS] 80 vs. >80, and the presence of brain, liver, or bone metastasis) were used to divide the IMDC favorable risk group into 2 new categories: very favorable and favorable risk groups. The primary endpoint was overall survival (OS). Time to treatment failure (TTF) and objective response rate (ORR) in the very favorable and favorable risk groups were the secondary endpoints. RESULTS: A total of 545 patients with mRCC from all IMDC risk groups and 112 patients from the favorable risk group were included in this study. According to the novel classification model, 44 (39.3%) and 68 (60.7%) patients with former favorable risk were categorized into very favorable and favorable risk groups, respectively. The median OS (55.8 months vs. 34.2 months, P = .025) and TTF (25.5 months vs. 15.5 months, P = .010) were longer in the very favorable risk group than in the favorable risk group. The concordance index of the new IMDC model in all patients was 0.65 for OS. Despite the higher ORR in the very favorable risk group than in the favorable risk group, the difference between the groups was not statistically significant (52.4% vs. 44.7, P = .573). CONCLUSIONS: This was the first study to externally validate the novel IMDC risk model presented in the American Society of Clinical Oncology Genitourinary Cancers Symposium 2021.

This study aims to investigate the prognostic value of the systemic immune-inflammation index (SII)and its impact on survival in patients with metastatic renal cell carcinoma (mRCC). A total of 706patients with mRCC treated with tyrosine kinase inhibitors (TKIs)between January 2007 and June 2020 (i.e., sunitinib, pazopanib) were included in this study. SII was calculated in 621 patients with the following formula:[neutrophil (cellsx109/L) x platelet (cellsx109/L)] / lymphocyte (cellsx109/L).All patients were classified into SII-high and SII-low groups based on the cut-off value of SII at 756, which was the median SII level of our study group. The minimal follow-up duration was 10 months in all cohorts. The median age of patients was 60 (interquartile range (IQR):53-67) years. Three out of four patients were male. The majority of patients (85.7%) had clear cell histology, and sarcomatoid differentiation was observed in 16.9% of all patients. There were 311 and 310 patients in the SII-low and SII-high groups, respectively. In general, baseline characteristics were similar in each group. However, the rate of patients treated with sunitinib (63.3% vs. 49.0%, p < 0.001) and those who underwent nephrectomy (83.6% vs. 64.2%, p < 0.001) was higher in the SII-low group than in the SII-high group. On the other hand, patients with the IMDC poorrisk (31.6% vs. 8.0%, p < 0.001), those with bone (51.8% vs. 32.2%, p < 0.001) or central nervous system (12.9% vs. 5.8%, p = 0.026) metastasis, and those with Eastern Cooperative Oncology Group(ECOG) 2-4 performance score (28.1% vs.17.7%, p = 0.002) were more common in the SII-high group than in the SII-low group. The median overall survival (OS) was longer in the SII-low group than in the SII-high group (34.6 months vs. 14.5 months, p < 0.001). Similarly, the median progression-free survival (PFS) was longer in the SII-low group than in the SII-high group (18.0 months vs. 7.7 months, p < 0.001).In multivariableanalysis, SII was an independent prognostic factor for OS (hazard ratio (HR):1.39, 95% confidence interval (CI):1.05-1.85, p = 0.01) and PFS (HR:1.60, 95% CI:1.24-2.05, p < 0.001).Pre-treatment level of high SII might be considered a predictor of poor prognosisin patients with mRCC treated with TKIs.

AIM: To compare survival outcomes, response rates, and adverse events (AEs) in proton pump inhibitor (PPI) user and non-user patients with metastatic colorectal cancer (mCRC) treated with regorafenib. METHODS: We included 272 patients with mCRC treated with regorafenib in this study. Patients were divided into two categories according to their status of PPI use. The primary endpoint was overall survival (OS). The secondary endpoints were time to treatment failure (TTF), response rates, and safety. To exclude immortal time bias in survival analyses, we compared PPI non-user patients and all patients. RESULTS: There were 141 and 131 patients in the PPI non-user and user groups. Baseline characteristics were similar in each group. Pantoprazole was the most used PPI. At the median 35.2 (95% confidence interval (CI): 32.6-37.9) months follow-up, the median OS was similar in PPI non-user and all patients (6.9 months (95% CI: 5.3-8.5) and 7.7 months (95% CI:6.6-8.8), p = 0.913). TTF was also similar in PPI non-user and all patients (3.3 months (95% CI: 2.7-3.9) and 3.5 months (95% CI: 3.0-4.0), p = 0.661). In multivariable analysis, no statistically significant difference was observed between PPI user and non-user groups in OS and TTF (hazard ratio (HR), 0.99; 95% CI, 0.77-1.28; p = 0.963 for OS; HR, 0.93; 0.77-1.20, p = 0.598 for TTF). The objective response rates (ORR) were similar in the PPI non-user and user groups (19.8% and 16.8%, p = 0.455). The rates of any grade AEs were also similar in each group. CONCLUSION: This study found no worse outcome in the combined use of PPI and regorafenib among patients with mCRC.

Immune checkpoint inhibitors (ICIs) have started a new era in treating patients with cancer. The effect of comorbidities and concomitant drug use on ICIs have become of interest in those patients. Data about the impact of hyperglycemia on response to ICIs in cancer patients are limited. All advanced-stage cancer patients treated with ICIs in Ankara University Medical Oncology Department were retrospectively evaluated. Patients treated in expanded access programs or clinical trials were excluded from the study. A total of 137 patients were included in this study. The most common primary tumor type was malign melanoma (32.8%) and nivolumab (62.3%) was the most common used ICI. More than half of patients (57.7%) had lung metastasis at the initiation of ICIs. Thirty-five patients (25.5%) had diabetes before initiating ICIs. Median baseline fasting glucose level was higher in patients with diabetes than those without diabetes (117 mg/dl vs. 99 mg/dl, P = 0.002). In all patients, median overall survival and progression-free survival were 11.3 [95% confidence interval (CI), 8.1-14.4) and 5.9 (95% CI, 3.6-8.3) months, respectively. In multivariate analysis, diabetes was found to increase risk of death [hazard ratio (HR), 2.09; 95% CI, 1.27-3.43, P = 0.004) and disease progression (HR, 2.01, 95% CI, 1.29-3.09, P = 0.002). Hyperglycemia might decrease response to ICIs in patients with advanced cancer. This research area is still an unmet need in the immunotherapy era. Prospective studies are needed to elucidate the effect of hyperglycemia on the response to ICIs.

AIM: To assess the prognostic effect of pan-immune inflammation value (PIV) in patients with metastatic castration-resistant prostate cancer (mCRPC) treated with abiraterone acetate (AA) or enzalutamide. METHODS: Patients with mCRPC treated with AA or enzalutamide between January 2010 and June 2021 were included in this study. The most recently examined complete blood count values in the 1-month period before treatment were used for calculating PIV. The relationship between overall survival (OS) and PIV was evaluated by multivariate analysis. By using PIV and lactate dehydrogenase (LDH) levels which had shown survival effect at multivariate analysis, PIV-LDH combined score was established. RESULTS: A total of 114 patients were included in this study. At the median follow-up of 34.6 months (95% confidence interval [CI]: 32.4-36.8), the median OS was 21 months (95% CI: 17.6-21.3). The median OS in the low-PIV group was significantly higher than in the high-PIV group (34.4 months (95% CI: 21.3-47.5) vs. 14.3 months (95% CI: 10.0-18.7), p < 0.001). In the multivariate analysis for OS, high PIV (hazard ratio [HR]: 1.86, 95% CI: 1.11-3.13, p = 0.018) and LDH value 1.5 times the upper limit of normal and above (HR: 3.65 95%, CI: 1.86-7.16, p < 0.001) were associated with shorter OS. When survival analysis was performed according to the PIV-LDH combined score, the median OS was 34.4 months (95% CI: 22.2-46.6) in the low-risk group, 17.7 months (95% CI: 11.7-23.6) in the intermediate-risk group, and 8.4 months (95% CI: 5.1-11.7) in the high-risk group (p < 0.001). The C-index of the combined PIV-LDH score was higher than the C-index of PIV (0.65 vs. 0.61). CONCLUSION: In this study, we demonstrated that PIV was an independent prognostic factor for OS in patients with mCRPC treated with AA or enzalutamide. Additionally, PIV-LDH combined score may be considered a promising composite peripheral blood-based biomarker to predict OS in those patients.

Aim To assess the actionable genomic landscape of colon adenocarcinoma in the primary and metastatic tumor tissues. Methods The data from the American Association for Cancer Research (AACR) Project Genomics Evidence Neoplasia Information Exchange (GENIE) were used in this study. Colon adenocarcinoma patients with primary and metastatic tissue samples (distant organ and lymph node) were selected. Patients with samples from a local recurrence, not otherwise specified tumor samples, and data not collected for sampling localization were excluded. Results A total of 3286 and 1727 patients were included in the primary and metastatic tissue sample groups, respectively. There was no difference between the groups in Kirsten rat sarcoma viral oncogene homolog (KRAS) mutation rates. The rates of v-Raf murine sarcoma viral oncogene homolog B (BRAF) and mismatch repair (MMR) gene mutations were higher in the primary tumor tissues than in the metastatic tumor tissues. There was also no difference between the groups in other actionable gene alterations (e.g. ERBB2 amplification and neurotrophic receptor tyrosine kinase (NTRK) 1 and NTRK3 fusions). In contrast to all cohorts, in Asian and black patients, there was no difference in actionable genomic landscape between the primary and metastatic tumor tissues. Conclusion This study had the largest number of colon cancer patients that evaluated the actionable genomic alterations in primary and metastatic tumor tissues. BRAF and MMR gene alterations were more frequent in the primary tumor tissues than the metastatic tumor tissues.
RESUMO
BACKGROUND: Pan-immune-inflammation value (PIV) is an easily accessible immune marker based on peripheral blood to estimate prognosis in patients with cancer. This study evaluates the prognostic value of PIV in patients with metastatic renal cell carcinoma (mRCC) treated with nivolumab. METHODS: In this retrospective cohort study, patients with mRCC treated with nivolumab in the second line and beyond were selected from the Turkish Oncology Group Kidney Cancer Consortium (TKCC) database. PIV was calculated using the following formula: neutrophil (103/mm3) x monocyte (103/mm3) x platelet (103/mm3)/lymphocyte (103/mm3). RESULTS: A total of 152 patients with mRCC were included in this study. According to cut-off value for PIV, 77 (50.7%) and 75 (49.3%) patients fell into PIV-low ([Formula: see text] 372) and PIV-high (> 372) groups, respectively. In multivariate analysis, PIV-high (HR: 1.64, 95% CI 1.04-2.58, p = 0.033 for overall survival (OS); HR: 1.55, 95% CI 1.02-2.38, p = 0.042 for progression-free survival (PFS)) was independent risk factor for OS and PFS after adjusting for confounding variables, such as performance score, the International mRCC Database Consortium (IMDC) risk score, and liver metastasis. CONCLUSION: This study established that pre-treatment PIV might be a prognostic biomarker in patients with mRCC treated with nivolumab in the second line and beyond.
