RESUMO
Trastuzumab emtansine (T-DM1) is a mainstay therapy for HER2-positive metastatic breast cancer (mBC). However, identifying patients who will benefit most remains a challenge due to the lack of reliable biomarkers. The recently developed pan-immune-inflammation value (PIV), a novel immune-inflammation marker, could aid in this regard, considering the immunomodulatory effects of T-DM1. Therefore, we aimed to evaluate the association between the PIV and the efficacy of T-DM1 in patients with HER2-positive mBC. A total of 122 HER2-positive mBC patients treated with T-DM1 were included. Receiver operating characteristic (ROC) curve analyses were conducted to determine the optimal PIV threshold value for survival prediction. Kaplan-Meier survival curves and Cox regression analyses were used for univariable and multivariable survival analyses, respectively. The median age was 51 years, and 95.1% of the patients had ECOG PS 0-1. The optimal PIV cutoff value was identified as 338 in ROC analyses (AUC: 0.667, 95% CI: 0.569-0.765, p = 0.002). The multivariate analysis revealed that patients in the high-PIV group had significantly shorter OS (HR: 2.332; 95% CI: 1.408-3.861; p = 0.001) and PFS (HR: 2.423; 95% CI: 1.585-3.702; p < 0.001) than patients in the low-PIV group. Additionally, both ORR and DCR were significantly lower in the high-PIV group (36.6% vs. 61.3%, p = 0.011; 56.1% vs. 76.0%, p = 0.027). Our findings suggest that pre-treatment PIV may be a novel prognostic biomarker for HER2-positive mBC patients receiving T-DM1. A low PIV level is associated with more favorable outcomes. Future prospective studies are warranted to validate these findings and explore the potential utility of PIV in aiding treatment decisions.
RESUMO
OBJECTIVE: To investigate the impact of cumulative cisplatin dose on clinical outcomes in locally advanced cervical cancer patients undergoing definitive chemoradiotherapy. METHODS: A retrospective analysis was conducted on 654 patients with stage IB3-IVA disease treated with definitive chemoradiotherapy. Radiotherapy was applied as external beam pelvic with or without para-aortic radiotherapy and brachytherapy. Concomitant chemotherapy was in the form of weekly or 3 weekly cisplatin. Data on demographics, treatment protocols, cumulative cisplatin dose, adverse effects, and survival outcomes were collected. Statistical analyses, including univariate and multivariate Cox regression models, were used to assess factors influencing progression free survival and overall survival. RESULTS: The median cumulative cisplatin dose was 210 mg (range 40-320), and ≥200 mg in 503 (76.9%) patients. Median follow-up was 35 months (range 1-150). The 5 year progression free survival and overall survival rates were 66.9% and 77.1%, respectively. Multivariate analysis identified poor performance status, non-squamous cell histology, presence of lymph node metastases, and hemoglobin <10 g/dL before chemoradiotherapy as poor prognostic factors for both progression free survival and overall survival in the whole group. When stage III cases were evaluated separately, the cumulative cisplatin dose <200 mg was found to be a significant poor prognostic factor in overall survival (hazard ratio 1.79, 95% confidence interval 1.1 to 3.0, p=0.031). CONCLUSION: Our study showed that a cumulative cisplatin dose >200 mg, particularly in patients with lymph node metastases, significantly improved overall survival. Factors such as anemia, toxicity related challenges, and comorbidities were identified as critical considerations in treatment planning. These findings emphasize the balance between maximizing therapeutic efficacy and managing toxicity, guiding personalized treatment approaches for locally advanced cervical cancer.
RESUMO
OBJECTIVES: Head and neck cancers (HNCs) represent a significant global health concern due to high morbidity and mortality rates. Despite therapeutic advances, the prognosis for advanced or recurrent cases remains challenging. Nivolumab obtained approval for recurrent or metastatic HNC based on the Phase III CheckMate 141 trial. This study aimed to evaluate the real-world outcomes of nivolumab in patients with non-nasopharyngeal HNC. DESIGN: In this multicenter retrospective study, we analyzed 124 patients with recurrent or metastatic non-nasopharyngeal HNC who received nivolumab in the second-line setting and beyond. Data were collected from 20 different cancer centers across Turkey. The effectiveness and safety of the treatment and survival outcomes were evaluated. RESULTS: Nivolumab exhibited favorable clinical responses, yielding an objective response rate of 29.9% and a disease control rate of 55.7%. Safety assessments revealed a generally well-tolerated profile, with no instances of treatment discontinuation or mortality due to side effects. Survival analysis disclosed a median overall survival (OS) of 11.8 (95% CI 8.4-15.2) months. Multivariate analysis revealed that ECOG-PS ≥ 1 (HR: 1.64, p = 0.045), laryngeal location (HR: 0.531, p = 0.024), and neutrophil-to-lymphocyte ratio > 3.5 (HR: 1.97, p = 0.007) were independent predictors of OS. CONCLUSIONS: Nivolumab is an effective and safe treatment option for patients with recurrent or metastatic non-nasopharyngeal HNC in real-world settings. Further studies are needed on factors affecting response to treatment and survival outcomes.
RESUMO
This study addresses the gap in understanding the prognostic relevance of hypoxia-inducible factor-1 alpha (HIF-1 alpha) expression in metastatic cervical squamous cell carcinoma (SCC) patients undergoing anti-vascular endothelial growth factor (VEGF)-based therapy. A retrospective multicenter study (n = 34) explored HIF-1 alpha expression via immunohistochemistry in patients treated with platinum chemotherapy and bevacizumab. Median progression-free survival (PFS) was significantly lower in the HIF-1 alpha low score group compared to the high score group (4.9 vs 12.9 months, P = 0.014). Similarly, the median overall survival (OS) was significantly reduced in the HIF-1 alpha low score group (8.3 vs 20.4 months, P = 0.006). This study, the first of its kind, highlights the prognostic significance of HIF-1 alpha expression in metastatic cervical SCC patients treated with bevacizumab-based therapy.

AIM: Sirolimus, a mammalian target of rapamycin inhibitor, inhibits cell growth and proliferation by controlling ribosome biogenesis and protein synthesis in vascular anomalies and cancers. However, most sirolimus studies on vascular anomalies were conducted in the pediatric population, with limited data in adults. In this study, we assessed the effectiveness and safety of sirolimus in adult patients with vascular malformation, a subtype of vascular anomaly. METHODS: We conducted a retrospective analysis of adult vascular malformation patients aged over 16, treated at Hacettepe University Cancer Institute from January 2013 to September 2022. Patient demographics and clinical characteristics were recorded. The primary outcome was the efficacy of sirolimus evaluated by response and disease control rates. The disease control rate was defined as the cumulative percentage of complete or partial responses, along with stable disease. The secondary endpoint was toxicity and safety. RESULTS: 38 patients with a median age of 21 (IQR: 18-33) were recruited. Prior to sirolimus treatment, 57.9% of patients had undergone other therapeutic interventions, predominantly sclerotherapy and surgery. The median follow-up time during sirolimus treatment was 18.5 (IQR: 11.3-74.5) months. The disease control rate was 92.1% (35/38). Head-neck localization was associated with better response rates (p = .001). Sirolimus was generally well tolerated and grade 1 or 2 oral mucositis (n = 4) and skin rash (n = 3) were the most common side effects. CONCLUSION: In this study, we found sirolimus was efficacious and well tolerated in adult patients with vascular malformation.
RESUMO
The study analysed the clinical characteristics, treatment approaches, and survival outcomes of 97 consecutive patients with orbital lymphoma (OL) over a 25-year period at. The median age of the patients was 57.6 years, and 59.8% (n = 58) were male. Marginal zone lymphoma constitutes the most prevalent subtype, accounting for 67% of cases, whereas other common subtypes include diffuse large B-cell lymphoma, follicular lymphoma, mantle cell lymphoma, Burkitt lymphoma, and T-cell lymphomas. Unilateral involvement was observed in the majority of cases (72.3%). Common clinical presentations included mass (30.9%), swelling (26.8%), and epiphora (11.3%). Of the patients, 7.2% received rituximab alone, 14.4% received radiotherapy alone, 48.5% received chemotherapy, 27.8% received radiotherapy plus rituximab, 22.7% received radiotherapy plus chemotherapy, and 5.2% underwent surgery as the first-line treatment. During a median follow-up of 4.3 years, 15.5% of patients experienced relapse or disease progression. The 5-year and 10-year progression-free survival rates were 84.1% and 79.1%, respectively. This study contributes to our understanding of OLs and provides a foundation for further investigations in this field. Male gender, presence of B symptoms, advanced stage, secondary orbital lymphoma, aggressive histological subtype, and elevated serum lactate dehydrogenase levels were associated with poorer (either inferior or worse) progression-free survival.

The aim of the study was to evaluate the real-world clinical outcomes of atezolizumab and bevacizumab (Atez/Bev) as the initial therapy for advanced hepatocellular carcinoma (HCC). We retrospectively analyzed 65 patients treated with Atez/Bev for advanced HCC from 22 institutions in Turkey between September 2020 and March 2023. Responses were evaluated by RECIST v1.1 criteria. The median progression-free survival (PFS) and overall survival (OS) were calculated using the Kaplan-Meier method. Cox regression model was employed to conduct multivariate analyses. The median age was 65 (range, 22-89) years, and 83.1% of the patients were male. A total of 1.5% achieved a complete response, 35.4% had a partial response, 36.9% had stable disease, and 26.2% had progressive disease. The disease control rate was 73.8% and associated with alpha-fetoprotein levels at diagnosis and concomitant antibiotic use. The incidence rates of any grade and grade ≥ 3 adverse events were 29.2% and 10.7%, respectively. At a median follow-up of 11.3 (3.4-33.3) months, the median PFS and OS were 5.1 (95% CI: 3-7.3) and 18.1 (95% CI: 6.2-29.9) months, respectively. In univariate analyses, ECOG-PS ≥ 1 (relative to 0), Child-Pugh class B (relative to A), neutrophil-to-lymphocyte ratio (NLR) > 2.9 (relative to ≤ 2.9), and concomitant antibiotic use significantly increased the overall risk of mortality. Multivariate analysis revealed that ECOG-PS ≥ 1 (HR: 2.69, P = .02), NLR > 2.9 (HR: 2.94, P = .017), and concomitant antibiotic use (HR: 4.18, P = .003) were independent predictors of OS. Atez/Bev is an effective and safe first-line therapy for advanced-stage HCC in a real-world setting. The survival benefit was especially promising in patients with a ECOG-PS score of 0, Child-Pugh class A, lower NLR, and patients who were not exposed to antibiotics during the treatment.

INTRODUCTION: This study aims to report the efficacy and safety of capecitabine plus temozolomide (CAPTEM) across different lines of treatment in patients with metastatic neuroendocrine tumors (NETs). METHODS: We conducted a multicenter retrospective study analyzing the data of 308 patients with metastatic NETs treated with CAPTEM between 2010 and 2022 in 34 different hospitals across various regions of Turkey. RESULTS: The median follow-up time was 41.0 months (range: 1.7-212.1), and the median age was 53 years (range: 22-79). Our results across the entire patient cohort showed a median progression-free survival (PFS) of 10.6 months and a median overall survival (OS) of 60.4 months. First-line CAPTEM treatment appeared more effective, with a median PFS of 16.1 months and a median OS of 105.8 months (median PFS 16.1, 7.9, and 9.6 months in first-, second- and ≥third-line respectively, Pâ =â .01; with median OS values of 105.8, 47.2, and 24.1 months, respectively, Pâ =â .003) In terms of ORR, the first-line treatment again performed better, resulting in an ORR of 54.7% compared to 33.3% and 30.0% in the second and third or higher lines, respectively (Pâ <â .001). Grade 3-4 side effects occurred only in 22.5% of the patients, leading to a discontinuation rate of 9.5%. Despite the differences in outcomes based on treatment line, we did not observe a significant difference in terms of side effects between the first and subsequent lines of treatment. CONCLUSIONS AND RELEVANCE: The substantial superior outcomes in patients receiving first-line CAPTEM treatment highlight its potential as an effective treatment strategy for patients with metastatic NET.

Aim: To assess the prognostic role of the CA-125 elimination rate constant K (KELIM) score in platinum-resistant/refractory ovarian cancer patients receiving second-line treatment. Methods: A retrospective study was carried out including 117 patients with advanced-stage platinum-resistant/refractory ovarian cancer treated with liposomal doxorubicin ± bevacizumab. The KELIM score, calculated using CA-125 measurements within the first 100 days of chemotherapy, was used. Survival analyses were performed for overall survival (OS) and progression-free survival (PFS). Results: Higher KELIM scores were associated with a superior PFS and OS. Multivariate analysis confirmed the independent prognostic value of the KELIM score for OS. Validation cohorts showed consistent results. Conclusion: KELIM score may serve as a valuable prognostic marker for predicting OS and PFS in platinum-resistant/refractory ovarian cancer patients receiving second-line treatment. Prospective studies are needed for validation.
This study aimed to investigate the usefulness of a scoring system called CA-125 elimination rate constant K (KELIM) in predicting the outcomes of ovarian cancer patients who are resistant to or have not responded to platinum-based treatments and are receiving a second-line treatment. The researchers conducted a retrospective (backwards looking) study involving 117 patients with advanced-stage ovarian cancer. They analyzed the patients' CA-125 levels within the first 100 days of chemotherapy to calculate the KELIM score. The results showed that higher KELIM scores were associated with better progression-free survival (the length of time during and after the treatment of a disease, that a patient lives with the disease but it does not get worse) and overall survival (the length of time from either the date of diagnosis or the start of treatment for a disease that patients diagnosed with the disease are still alive). Further analysis confirmed that the KELIM score was an independent predictor of overall survival. The findings were consistent when validated with additional patient groups. In conclusion, the KELIM score has the potential to be a useful tool for predicting the outcomes of ovarian cancer patients undergoing second-line treatment. However, further prospective studies are necessary to validate these findings.

Human epidermal growth factor receptor 2 (HER2)-targeting therapies have become crucial in the management of HER2-positive breast cancer. Trastuzumab emtansine (T-DM1) is a microtubule inhibitor and HER2-targeted antibody conjugate. T-DM1 resistance is most likely influenced by factors involved in the biological mechanisms of T-DM1 action. This study aimed to examine the efficacy of statins, which influence HER-2-based therapies via the caveolin-1 (CAV-1) protein, in female breast cancer patients receiving T-DM1. Our study included 105 patients with HER2-positive metastatic breast cancer treated with T-DM1. The progression-free survival (PFS) and overall survival (OS) of patients who received statins concurrently with T-DM1 versus those who did not were compared. During the median 39.5 (95% confidence interval [CI]: 35.6-43.5) months of follow-up, 16 (15.2%) patients received statins, and 89 (84.8%) patients did not. Median OS was significantly higher in patients using statins than in patients not using statins (58.8 vs 26.5 months, P = .016). The association between statin use and PFS did not reach statistical significance (34.7 vs 9.9 months, P = .159). Multivariate Cox regression analysis showed that better performance status (hormone receptor [HR]: 0.30, 95% CI: 0.13-0.71, P = .006), use of trastuzumab plus pertuzumab prior to T-DM1 (HR: 0.37, 95% CI: 0.18-0.76, P = .007) and use of statins with T-DM1 (HR: 0.29, 95% CI: 0.12-0.70, P = .006) were independent factors that prolong OS duration. Our study showed that T-DM1 is more effective at treating HER2-positive breast cancer in people who receive statins concurrently with T-DM1 than those who do not.

BACKGROUND: There are biological distinctions between gastric cancers from Eastern and Western nations, and therapeutic strategies may differ regionally. Perioperative chemotherapy, adjuvant chemotherapy, and adjuvant chemoradiotherapy (CRT) have all been demonstrated to be effective in the treatment of gastric cancer. The goal of this study was to do a meta-analysis of published studies that were eligible to see if adjuvant chemoradiotherapy was helpful for gastric cancer based on the cancer's histology. METHOD: From inception to May 4, 2022, manual searches were conducted to identify all eligible literature using the PubMed database for the published phase III clinical trial and a randomize-controlled trial testing the role of adjuvant chemoradiotherapy in operable gastric cancer. RESULTS: Two trials with a total of 1004 patients were selected as a result. Adjuvant CRT was found to have no effect on disease-free survival (DFS) in gastric cancer patients treated with D2 surgery (HR: 0.70 (0.62-1.02), p: 0.07). However, patients with intestinal-type gastric cancers exhibited significantly longer DFS (HR: 0.58 (0.37-0.92), p = 0.02). DISCUSSION: After D2 dissection, adjuvant CRT improved DFS in patients with intestinal-type gastric cancers but not in those with diffuse-type gastric cancers.

INTRODUCTION: There have been significant advances in the treatment of hepatobiliary cancers, especially for advanced-stage disease. However, data is limited for optimal therapy selection in the first line and sequencing of available options. AREAS COVERED: This review covers the systemic treatment of hepatobiliary cancers with an emphasis on the advanced stage. The previously published and ongoing trials will be discussed to create an algorithm for the current practice and to give future perspectives on how the field could go forward. EXPERT OPINION: While there is no standard-of-care option in the adjuvant treatment of hepatocellular cancer, capecitabine is the standard of care for biliary tract cancer. The efficacy of adjuvant gemcitabine and cisplatin and the added benefit of radiotherapy to chemotherapy are yet to be defined. For the advanced stage, immunotherapy-based combinations became the standard of care for both hepatocellular and biliary tract cancers. The molecularly targeted therapy has profoundly changed the second-line and later treatment for biliary tract cancers, while the optimal second-line treatment for advanced hepatocellular cancer is yet to be defined due to rapid advances in the first-line setting.

Pancreatic cancer is mostly metastaticat diagnosis. BR east CA ncer gene (BRCA) mutations are associated with platinum sensitivity in metastatic pancreatic cancer. However, curative surgery and complete remission are infrequent. In this report, we present a 42-year-old female patient diagnosed with BRCA-mutated pancreatic cancer with liver metastases. After 12 cycles of FOLFIRINOX, liver metastases disappeared and the patient underwent pancreaticoduodenectomy. The patient has been followed in complete remission for 5 years. To the best of our knowledge, the presented case is the longest recurrence-free survival after platinum-based therapy in metastatic pancreatic cancer with BRCA mutation. Our case emphasizes that investigating BRCA gene mutations at the time of diagnosis can be life-saving in these patients.

BACKGROUND/AIMS: We aimed to investigate the effects of glomerular IgM and C3 deposition on outcomes of adult patients with primary focal segmental glomerulosclerosis (FSGS). METHODS: In this retrospective analysis, 86 consecutive adult patients with biopsy-proven primary FSGS were stratified into 3 groups according to their histopathological features: IgM- C3-, IgM+ C3-, and IgM+ C3+. Primary outcome was defined as at least a 50% reduction in baseline estimated glomerular filtration rate (eGFR) or development of kidney failure, while complete or partial remission rates were secondary outcomes. RESULTS: Glomerular IgM deposits were found in 44 (51.1%) patients, 22 (25.5%) of which presented with accompanying C3 deposition. Patients in IgM+ C3+ group had higher level of proteinuria (5.6 g/24 h [3.77-8.5], p = 0.073), higher percentage of segmental glomerulosclerosis (20% [12.3-27.2], p = 0.001), and lower levels of eGFR (69 ± 37.2 mL/min/1.73 m2, p = 0.029) and serum albumin (2.71 ± 0.85 g/dL, p = 0.045) at the time of diagnosis. Despite 86.3% of patients in IgM+ C3+ group (19/22) received immunosuppressive treatment, the primary outcome was more common in patients in the IgM+ C3+ group compared with patients in IgM+ C3- and IgM- C3- groups (11 [50%] vs. 2 [9%] and 11 [26.1%] respectively [p = 0.010]). Complete or partial remission rates were lower in patients in the IgM+ C3+ group (5/22, 22.7%), as well (p = 0.043). Multivariate Cox regression analysis revealed that IgM and C3 co-deposition was an independent risk factor associated with primary outcome (hazard ratio 3.355, 95% CI 1.349-8.344, p = 0.009). CONCLUSIONS: Glomerular IgM and C3 co-deposition is a predictor of unfavorable renal outcomes in adult patients with primary FSGS.

BACKGROUND Cytomegalovirus (CMV) and BK virus (BKV) are post-transplant opportunistic viral infections that affect patient and graft survival. This study was designed to evaluate the risk of BKV nephropathy and CMV disease in kidney transplant recipients who received induction therapy with ATG or basiliximab. MATERIAL AND METHODS We retrospectively analyzed information on 257 adult patients who underwent kidney transplantation between January 2007 and 2017. Patients were categorized into 3 groups according to the induction therapies. The primary endpoint was the onset of CMV disease or biopsy-confirmed BKV nephropathy. The secondary endpoints were biopsy-proven rejection episodes, graft loss, loss to follow-up, and death. RESULTS We followed 257 patients for a median of 55.5 months. The incidence of CMV disease was significantly higher in the only ATG group compared to the group without induction treatment (p<0.001). There was no significant difference in the incidence of BKV nephropathy among groups (p>0.05). The dosage of ATG (OR, 10.685; 95% CI, 1.343 5 to 85.009; P=0.025) was independent risk factor for death. CONCLUSIONS This study demonstrated that a higher dosage of ATG in high-risk patients is associated with an increased risk of CMV disease and patient death, also, reducing the dosage may be a rational strategy for increasing graft and patient's survival.
