The efficacy of modified docetaxel-cisplatin-5-fluorouracil regimen as first-line treatment in patients with alpha-fetoprotein producing gastric carcinoma

Alpha-fetoprotein producing gastric carcinoma (AFP-PGC) is a rare cancer for which limited data on the clinicopathological features and treatment modalities exist. The aim of this study was to compare the efficacy of modified docetaxel-cisplatin-5-fluorouracil (mDCF) as the first-line chemotherapy regimen in metastatic AFP-PGC and non-AFP-PGC. The patients diagnosed with metastatic gastric cancer who were given mDCF as first-line therapy were retrospectively reviewed. The patients with a basal serum AFP level over 9 ng/ml were defined as AFP-PGC patients. In total, 169 patients (34 with AFP-PGC and 135 with non-AFP-PGC) were included in this study. AFP-PGC patients had more liver metastases than non-AFP-PGC patients (p < 0.001). A decrease in basal AFP levels after three cycles of chemotherapy was significantly different in AFP-PGC group (p = 0.001).Overall disease control rate was 79.4% (partial response [PR] - 44.1%, stable disease [SD] - 35.3%), and 82.2% (complete response - 3%, PR - 36.2%, SD - 43%) in AFP-PGC and non-AFP-PGC patients, respectively. There was no difference between AFP-PGC and non-AFP-PGC groups in overall and progression-free survival rates (11.3 versus 11.4 months and 7.7 versus 7.1 months, respectively). Rates of grade 3-4 hematologic toxicity were 8.8% and 6.7% for neutropenia in AFP-PGC and non-AFP-PGC group, respectively and 5.9% and 7.4% for anemia. In conclusion, mDCF regimen is well-tolerated with acceptable toxicity outcomes in both AFP-PGC and non-AFP-PGC patients. A statistically significant decrease in AFP levels after mDCF regimen indicate that AFP might be considered as a supplemental marker of response to mDCF chemotherapy in AFP-PGC patients. However, further prospective clinical trials are required in this area

The impact of HER2-low status on pathological complete response and disease-free survival in early-stage breast cancer

BackgroundThe HER-2 status of breast cancer (BC) has been classified as negative or positive for a long time. Given the efficacy of novel anti-HER2-targeted antibody drug conjugates (ADCs) in HER2-low BC, a distinct subgroup of HER2-low tumors has emerged within BC. The biology and prognostic impact of HER2-low expression are not yet well defined, and inconsistent results were reported. This study aims to evaluate the impact of low HER-2 status on the response to neoadjuvant chemotherapy (NACT) and disease- free survival (DFS) rates.MethodsWe retrospectively analyzed BC patients treated with NACT from 2017 to 2023 in two cancer centers. HER2-negative patients were included. HER-2 low status was defined by IHC + 1 or + 2/ISH non-amplified, and HER2-zero was defined by IHC 0. Pathological complete response (pCR) rates and DFS between HER2-low and HER2-zero populations were compared.Results170 patients were identified. 122 (72%) of these patients were HER2- zero BC, whereas 48 (28%) were HER2-low BC. Overall, pCR was achieved in 35 (20.5%) patients. Of these, pCR was observed in 30 patients (44.6%) from the HER2- zero group, compared to 5 patients (10.4%) from the HER2-low group (p = 0.046), but significance was lost in multivariate analysis. Among the hormone receptor (HR) positive subtype, pCR was achieved 19.8% of HER2-zero tumors and 7.5% of HER2-low tumors (p = 0.08). For HR-negative subtype 34.1% HER2-zero tumors had pCR and 25% of the HER2-low tumors had pCR (p = 0.614). There was no association between DFS and HER2-low status.ConclusionsOur study indicates that HER2-low status had no impact on pCR or DFS

Risk of Malnutrition and Its Effects on the Quality of Life of Hospitalized Cancer Patients

Aim:Malnutrition is one of the most common clinical problems in cancer patients. Its frequency increases in hospitalized cancer patients. In this study, it was aimed to investigate the frequency of malnutrition and its effect on quality of life (QOL) in hospitalized cancer patients.Materials and Methods:In this cross-sectional study, Nutrition Risk Screening-2002 (NRS-2002) and European Organization for the Research and Treatment of Cancer (EORTC)-QLQ C30 scales were completed for patients with cancer diagnosed in the medical oncology service. The relationship between clinical and laboratory parameters, malnutrition risk and QOL was analyzed by statistical methods.Results:One-hundred thirteen patients were included in the study. According to the results of NRS-2002, 42.5% (n=48) patients were at risk of malnutrition. There was no difference between the groups in terms of gender and age. When the EORTC-QLQ C30 scale scores were compared, the risk of malnutrition had no effect on the overall health score (p=0.679). Physical function and role function scores were significantly lower in those at risk of malnutrition (worse QOL). There was no statistically significant difference between the groups in terms of other functional scales. When univariate logistic regression (LR) was applied to the factors affecting better general health score, only hemoglobin level was found to be a significant factor. Therefore, multivariate LR was not done.Conclusion:Malnutrition risk assessment should be performed routinely in every hospitalized cancer patient. Early nutritional support should be given to patients at risk. It was observed that patients with malnutrition risk had worse QOL compared to the EORTC-QLQ C30 scale

Prognostic role of neutrophil-to-lymphocyte ratio (NLR) in patients with operable ampullary carcinoma

Ampullary carcinoma or cancer of the ampulla of Vater is a rare malignancy with a high recurrence rate. Although cost-effective biomarkers, such as neutrophil-to-lymphocyte ratio (NLR), have been investigated in other cancers for predicting postoperative prognosis in patients, studies on the role of NLR in ampullary cancer are scarce. Here we aimed to evaluate the prognostic significance of preoperative NLR in patients with operable ampullary carcinoma. We retrospectively reviewed 87 patients who underwent pancreaticoduodenectomy for the treatment of ampullary carcinoma between December 1999 and April 2014. The association between NLR and prognosis (overall survival [OS] and disease-free survival [DFS]) was evaluated. Possible correlations between NLR and clinicopathological features were also assessed. The 5-year DFS and OS rates after surgery in patients with ampullary carcinoma were 51% and 63%, respectively. A high NLR (≥3.0) was found in 40 patients. The NLR was a significant prognostic factor for both OS and DFS. Multivariate analysis revealed a significantly worse OS in patients with positive surgical margins and NLR ≥3 (p = 0.001). Patients with T3-T4 stage (p = 0.029) and NLR ≥3 (p = 0.043) had a lower DFS. Patients with a high NLR had a significantly worse Eastern Cooperative Oncology Group performance score. Preoperative NLR is an independent and significant predictive factor of prognosis in patients with ampullary carcinoma. An elevated pretreatment NLR (e.g., NLR ≥3) may be considered as a biomarker for poor prognosis in patients with ampullary carcinoma

A statistically significant decrease in AFP levels after mDCF regimen indicate that AFP might be considered as a supplemental marker of response to mDCF chemotherapy in AFP-PGC patients. However, further prospective clinical trials are required in this area

Bevacizumab-induced isolated oculomotor nerve palsy in glioblastoma multiforme

Introduction: Bevacizumab, a monoclonal antibody against the vascular endothelial growth factor receptor, is the standard treatment of recurrent glioblastoma multiforme. In addition to common systemic side effects of bevacizumab, there are rare cases of cranial nerve palsy. Case report: We report a case of transient oculomotor nerve palsy after systemic administration of bevacizumab. Twenty-four hours after the systemic infusion of bevacizumab, transient oculomotor nerve palsy developed in a 49-year-old male patient. In the cranial MRI, there was no malignancy-related progression. Management and outcome: Bevacizumab treatment was discontinued. Methylprednisolone was started considering that bevacizumab increased the inflammatory response. Oculomotor nerve palsy resolved in 14 days. Discussion: There are many side effects of bevacizumab whose mechanisms of action have not been fully explained. Cranial nerve involvement is rarely reported. Our case is the first reported case of bevacizumab-induced oculomotor nerve palsy

5-fluorouracil, leucovorin, and irinotecan (FOLFIRI) as a third-line chemotherapy treatment in metastatic gastric cancer, after failure of fluoropyrimidine, platinum, anthracycline, and taxane

Studies on the effects of third-line chemotherapy (CT) in advanced gastric cancer (GC) patients are still scarce. The aim of this study was to evaluate the efficacy and safety of the modified 5-fluorouracil, leucovorin, and irinotecan (mFOLFIRI) regimen as a third-line CT in metastatic GC patients, after failure of fluoropyrimidine, platinum, anthracycline, and taxane. After failure of first- and second-line therapies, 42 patients received third-line FOLFIRI (180 mg/m² irinotecan and 400 mg/m² leucovorin administered concomitantly as a 90-minute intravenous (IV) infusion on day 1, followed by a 400 mg/m² 5-fluorouracil IV bolus then 2600 mg/m² continuous infusion over 46 hours), between January 2009 and December 2015. FOLFIRI was administered for a median of 6 cycles (range 4-12 cycles). Eight patients achieved partial response, while 13 patients showed stable disease, resulting in the overall response rate (ORR) of 19% and disease control rate (DCR) of 50%. The most frequent grade 3-4 hematological and non-hematological toxicities were neutropenia (14.2%) and diarrhea (7.1%). The median progression-free survival (PFS) and overall survival (OS) from the start of third-line CT were 3.8 months (95% confidence interval [CI], 3.0-4.5) and 6.8 months (95% CI, 5.6-7.9), respectively. According to the multivariate analysis, two factors were independently predictive of the poor OS: >2 regions of metastasis (relative risk [RR], 2.6; 95% CI, 1.3-5.4) and a high level of carcinoembryonic antigen [CEA] (RR, 3.4; 95% CI, 1.6-7.4). In conclusion, FOLFIRI was well tolerated as third-line CT and showed promising PFS and OS in advanced GC patients, after failure of fluoropyrimidine, platinum, anthracycline, and taxane

The relationship between eGFR and capecitabine efficacy/toxicity in metastatic breast cancer

The objective of this study was to evaluate the efficacy and toxicity of capecitabine in metastatic breast cancer (mBC) according to the estimated glomerular filtration rate (eGFR). A total of 135 patients included in the final analysis were stratified into 3 categories according to baseline eGFR, i.e., eGFR 90 mL/min/1.73 m(2) (Group 3). If a patient developed a level of toxicity that would lead to capecitabine dose reduction, this was recognized as dose-limiting toxicity (DLT). The dose was reduced due to toxicity in 95 cycles. A total of 95 DLTs were seen in 76 (56.2%) of the 135 patients. When 76 patients with DLT were evaluated according to eGFR, DLT was observed in 93.3% of those in Group 1, 72.5% of those in Group 2 and 41.3% of those in Group 3 (p < 0.001). The median time to progression (TTP) of all patients was 7.4 months. No significant difference in TTP was observed in patients stratified into 3 groups according to eGFR. When the patients were divided into two groups as DLT and without DLT, the median TTP was 8.68 months (95% CI, 7.53-9.81 months) in those with toxicity and 6.23 months (95% CI, 4.04-8.43 months) in those without toxicity (log-rank p = 0.004). We found a significant relationship between low eGFR and increased risk of DLT. Having a DLT was associated with a longer TTP. It indicates the need for more data/larger study investigating these discrepancies
