lncRNA XIST Interacts with Regulatory T Cells within the Tumor Microenvironment in Chronic Hepatitis B-Associated Hepatocellular Carcinoma.

OBJECTIVE: Alterations in the expression of several long non-coding RNAs (lncRNAs) have been shown in chronic hepatitis B-associated hepatocellular carcinoma (CHB-HCC). Here, we aimed to investigate the association between the expression of inflammation-associated lncRNA X-inactive specific transcript (XIST) and the type of inflammatory cells within the tumor microenvironment. MATERIAL AND METHODS: Twenty-one consecutive cirrhotic patients with CHB-HCC were included. XIST expression levels were investigated on formalin-fixed paraffin-embedded (FFPE) tumoral and peritumoral tissue samples by real-time polymerase chain reaction (RT-PCR). Immunohistochemical staining for CD3, CD4, CD8, CD25, CD163, CTLA4, and PD-1 were performed. The findings were statistically analyzed. RESULTS: Of the 21 cases, 11 (52.4%) had tumoral and 10 (47.6%) had peritumoral XIST expression. No significant association was found between the degree of inflammation and XIST expression. The number of intratumoral CD3, CD4, CD8 and CD20 positive cells was higher in XIST-expressing tumors, albeit without statistical significance. Tumoral and peritumoral XIST expression tended to be more common in patients with tumoral and peritumoral CD4high inflammation. The number of intratumoral CD25 positive cells was significantly higher in XIST-expressing tumors (p=0.01). Tumoral XIST expression was significantly more common in intratumoral CD25high cases (p=0.04). Peritumoral XIST expression was also more common among patients with CD25high peritumoral inflammation, albeit without statistical significance (p=0.19). CONCLUSION: lncRNA XIST is expressed in CHB-HCC and its expression is significantly associated with the inflammatory tumor microenvironment, particularly with the presence and number of CD25 (+) regulatory T cells. In vitro studies are needed to explore the detailed mechanism.

The safety and efficacy of first-line atezolizumab plus bevacizumab in patients with unresectable hepatocellular carcinoma: A multicenter real-world study from Turkey.

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.

Factors Predicting Response in Breast Cancer Receiving Neoadjuvant Therapy and the Role of Ki67 Labeling Index.

OBJECTIVE: To determine the predictive value of Ki67 on pathological complete response (pCR) of breast and axilla regions in breast cancer (BC) patients receiving neoadjuvant therapy (NAT). STUDY DESIGN: Descriptive study. Place and Duration of the Study: Departments of Medical Oncology, Sirnak State Hospital, Aydin State Hospital, Manisa Celal Bayar University, and Dokuz Eylul University, from November 2010 to July 2022. METHODOLOGY: PCR and various histopathological parameters were evaluated for BC patients receiving NAT. The Youden Index method was used to find the cut-off value for the Ki67 variable according to the receiver operating characteristic (ROC) curve. This value was obtained as 77.5. Breast and axillary responses were individually evaluated to assess response to NAT. Univariate and multivariate logistic regression analysis were used to predict both breast and axillary pCR. RESULTS: A total number of 280 females receiving NAT for BC were included in the study. Multivariate analysis for breast pCR to NAT showed that Ki67 index (>77.5 vs <77.5, p=0.047) was statistically significant marker. While Ki67 index was significant for breast pCR in both univariate and multivariate analyses, the same was not observed on axillary response (p=0.387). CONCLUSION: High Ki67 level was significantly associated with breast pCR in BC patients receiving NAT, but a similar effect was not observed on axillary pCR. These findings suggest that breast and axilla tissues have a biological differences in treatment responses. KEY WORDS: Axillary response, Breast cancer, Ki67 Labeling Index, Neoadjuvant therapy, pathological complete response.

The Prognostic Significance of Circulating Tumor Cells in Patients with Pancreatobiliary Cancer.

BACKGROUND: Circulating tumor cells (CTCs) are cancer cells which separate from the primary tumor and enter systemic circulation. In this study, it was aimed to examine the relationship between CTCs isolated and identified from the peripheral blood of patients with pancreatobiliary cancer, with the clinicopathological characteristics of the patients and their overall survival. METHODS: A total of 21 patients were included the study. Density gradient centrifugation with the OncoQuick® assay was performed for isolation of CTCs from peripheral blood. In order to identify CTCs, enriched samples underwent flow cytometric analysis. RESULTS: The rate of patients with positive surgical margin in the high CTC group (CTC <15) was identified to be statistically significantly high compared to the group with low CTC (CTC ≤15) (83.3% vs. 16.7%; P = .041). Median neutrophil/lymphocyte ratio (NLR) was found to be higher in the high CTC group compared to the low CTC group, which was close to statistical significance (2.37 vs. 1.41; P = .055). CONCLUSIONS: Circulating tumor cells were identified to have a significant relationship with surgical margin positivity in our study for the first time, suggesting that the CTCs count in peripheral blood in preoperative patients may be a biomarker predicting positive surgical margin. Due to the very low number of studies assessing the relationship between CTCs and NLR, our study which identified relationship close to statistical significance between CTCs and NLR, significantly contributes to the literature on the topic of the possible role of lymphocytes in CTC clearance.

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.

Factors affecting overall survival and progression-free survival in patients with metastatic castration resistant prostate cancer received 177Lu PSMA I&T therapy.

OBJECTIVE: Lutetium-177 (177Lu) prostate specific membrane antigen (PSMA) radionuclide therapy (RNT) is an effective and safe treatment option in patients with metastatic castration resistant prostate cancer (mCRPC). The first aim of this study was to determine RNT response rate. The second and main aim of this study is measure overall and progression-free survival (OS and PFS) and to determine the factors have effect on OS and PFS. MATERIAL AND METHODS: Patients with mCRPC had 177Lu PSMA RNT every 6-8 weeks. Therapy response of each cycle determined wit PSA after 6-8 weeks. Overall survival and PFS were measured, then effects of age, Gleason grade, local recurrence, extraabdominopelvic located lymph node metastasis, visceral metastasis, prostate specific antigen (PSA) changing after the first RNT, pretreatment PSA, hemoglobin (Hb), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) values on survivals were determined. RESULTS: Forty-five patients were treated with total of 164 cycles of RNT. Fifteen patients (33%) had PSA decline of ≥50%, 23 patients (51%) showed any PSA decline and 20 patients (44%) showed PSA increase of ≥25%. Median OS and PFS were 17,1 months and 7,4 months. Patients had any or ≥50% PSA response after the first cycle, lower initial ALP (<120U/L) had longer OS and PFS. Patients had normal Hb showed longer OS and patients had lower initial PSA (<51ng/mL) had longer PFS. Patients had PSA progression of ≥25% had shorter OS and PFS. CONCLUSION: Prostate specific antigen response after the first cycle, lower initial ALP is related to longer OS and PFS. Normal pretreatment Hb is a predictor of longer OS and lower initial PSA is related to longer PFS. Prostate specific antigen progression after the first cycle causes shorter OS and PFS.

De Novo Malignancies After Liver Transplantation: A Single Institution Experience.

OBJECTIVES: Our objective was to analyze characteristics, risk factors, and incidence of de novo malignancies after liver transplant. MATERIALS AND METHODS: The hospital records of 557 patients who underwent liver transplant were analyzed from the point of de novo malignancy development. We evaluated the demographic features and survival of these patients retrospectively. RESULTS: The research covered 429 patients, 9 (2%) of whom developed de novo malignancy. All of these patients were male (100%), and their mean (SD) age was 51.33 (4.69) years (range, 45-65 y). Indications for transplant included alcohol related in 4 cases, chronic hepatitis B in 2 cases, chronic hepatitis B and C in 1 case, chronic hepatitis B and D in 1 case, and chronic hepatitis C and alcohol-related cirrhosis in 1 case. The mean (SD) time from transplant to cancer diagnosis was 63.41 (37.10) months (range, 17-122 mo). The types of tumors were lung cancer, lymphoma, neuroendocrine tumor of lung, nasopharyngeal cancer, and squamous cell carcinoma of the skin. Seven cases received chemotherapy with or without radiotherapy. Two cases received surgery and radiotherapy. One patient underwent surgical treatment. One patient died before treatment was started. CONCLUSIONS: In recent years, improvements in surgical techniques and immunosuppressive therapies have helped prolong survival of patients who undergo liver transplant. However, this also has led to a rise in the incidence of long-term complications such as de novo malignancy. These patients are more likely to develop de novo malignancy than the general population, for which chronic immunosuppression is identified as a major risk factor. Early diagnosis and treatment of de novo malignancies can help obtain better prognosis and higher survival rates in these patients.

Prognostic Value of the Pretreatment Neutrophil-to-Lymphocyte Ratio and Platelet-to-Lymphocyte Ratio for Patients with Neuroendocrine Tumors: An Izmir Oncology Group Study.

BACKGROUND: Several studies evaluating the prognostic factors of gastrointestinal and pancreatic neuroendocrine tumors (GEP-NETs) have been published. The neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) have been accepted as prognostic factors for cancer patients. MATERIALS AND METHODS: This study included 132 patients diagnosed with GEP-NETs. Peripheral blood samples were collected before the pretreatment period. RESULTS: NLR and PLR were increased as the grade increased in NETs. The embryonic origin analysis revealed higher NLR and PLR rates in NETs of foregut origin. NLR and PLR were also higher in pancreatic NET patients compared to the gastroenteric NET patients. Analysis of NETs by TNM indicated that an advanced stage was accompanied by significantly higher NLR and PLR. We found a strong negative correlation between progression-free survival and NLR and PLR. CONCLUSION: The study verified that NLR and PLR are simple laboratory findings that can be used to identify NETs with a worse outcome.

The association of clinicopathological features and survival in colorectal cancer patients with kras mutation status.

BACKGROUND: KRAS mutations have a significant role in the consecutive activation of RAS.RAF.MEK.ERK pathway in colorectal cancer.Approximately 30.35% of sporadic colorectal cancers have KRAS mutation. While the predictive role of KRAS is commonly accepted at the present time, its prognostic role and association with different clinical and histopathological properties are currently unclear and inconsistent. The intent of this study, has been to evaluate the associations between KRAS gene mutations and clinicopathological features and survival times in Turkish colorectal cancer patients. MATERIALS AND METHODS: In this study, the file records of 115 metastatic colorectal cancer patients who applied to the Department of Medical Oncology between 2000 and 2011 were monitored; data on clinicopathological features and survival times were collected. DNA.sequencing method with PCR amplification from archival paraffin blocks were used for KRAS mutation status analysis. The associations between KRAS mutation status and clinicopathological features and survival times were compared statistically. RESULTS: While a significant association hadbeen determined between KRAS mutation status and tumor localization, there was no determined significant association with other clinicopathological properties. Similarly, there was no association between KRAS mutation status and survival parameters. CONCLUSIONS: As a result, the effect of KRAS mutation status on clinicopathological features, survival time and prognosis is unclear.

Impact of adjuvant treatment modalities on survival outcomes in curatively resected pancreatic and periampullary adenocarcinoma.

BACKGROUND: We examined the impact of adjuvant modalities on resected pancreatic and periampullary adenocarcinoma (PAC). METHODS: A total of 563 patients who were curatively resected for PAC were retrospectively analyzed between 2003 and 2013. RESULTS: Of 563 patients, 472 received adjuvant chemotherapy (CT) alone, chemoradiotherapy (CRT) alone, and chemoradiotherapy plus chemotherapy (CRT-CT) were analyzed. Of the 472 patients, 231 were given CRT-CT, 26 were given CRT, and 215 were given CT. The median recurrence-free survival (RFS) and overall survival (OS) were 12 and 19 months, respectively. When CT and CRT-CT groups were compared, there was no significant difference with respect to both RFS and OS, and also there was no difference in RFS and OS among CRT-CT, CT and CRT groups. To further investigate the impact of radiation on subgroups, patients were stratified according to lymph node status and resection margins. In node-positive patients, both RFS and OS were significantly longer in CRT-CT than CT. In contrast, there was no significant difference between groups when patients with node-negative disease or patients with or without positive surgical margins were considered. CONCLUSIONS: Addition of radiation to CT has a survival benefit in patients with node-positive disease following pancreatic resection.

Clitoris metastasis from a retroperitoneal leiomyosarcoma: A case report.

Leiomyosarcoma is a rare form of cancer commonly found in the retroperitoneum, uterus, stomach, small intestine and vascular tissue. Surgery with a wide margin of resection is the most effective treatment. Nevertheless, metastasis is common and generally occurs within the first 3 years. The liver and lungs are the most common sites of metastasis in leiomyosarcoma. Other sites of metastasis include bone, spleen, soft tissues and brain. Metastatic tumours of the clitoris are extremely rare. As cited in the literature, the most common cancers that metastasize to the clitoris are breast, bladder, renal and gastric. Here, we report a case of a clitoral mass in a 64-year-old woman who received an operation for retroperitoneal leiomyosarcoma 4 years prior. Mass resection was performed. The pathological diagnosis was a leiomyosarcoma metastasis. The patient also presented with brain and lung metastases at the time of the clitoral metastasis. This is the first case of clitoral and brain metastases originating from a retroperitoneal leiomyosarcoma.

Long-term outcomes and prognostic factors of high-risk malignant melanoma patients after surgery and adjuvant high-dose interferon treatment: a single-center experience.

BACKGROUND: Surgical excision constitutes an important part of the treatment of local advanced malignant melanoma. Due to the high recurrence risk, adjuvant high-dose interferon therapy is still the only therapy used in stage IIB and III high-risk melanoma patients. METHODS: One hundred two high-risk malignant melanoma patients who received high-dose interferon-α-2b therapy were evaluated retrospectively. The clinicopathological features, survival times, and prognostic factors of the patients were determined. RESULTS: The median disease-free and overall survival times were 25.2 and 60.8 months, respectively. Our findings revealed that male gender, advanced disease stage, lymph node involvement, lymphatic invasion, the presence of ulceration, and a high Clark level were significant negative prognostic factors. CONCLUSION: In light of the favorable survival results obtained in this study, high-dose interferon treatment as adjuvant therapy for high-risk melanoma is still an efficient treatment and its possible side effects can be prevented by taking the necessary precautions.

Two-week combination chemotherapy with gemcitabine, high-dose folinic acid and 5 fluorouracil (GEMFUFOL) as first-line treatment of metastatic biliary tract cancers.

BACKGROUND: The aim of this study was to evaluate the efficacy and tolerability of a gemcitabine, 5-fluorouracil and leucovorin (GEMFUFOL) chemotherapy regimen as first line treatment of metastatic biliary tract cancer. MATERIALS AND METHODS: All patients received folinic acid 400 mg/m(2) on day 1, 5-fluorouracil bolus 400 mg/ m2 on day 1, IV infusion of 5-fluorouracil 2400 mg/m(2) over 46 hours, and gemcitabine 1250 mg/m(2) on day 1. RESULTS: A total of 29 patients with metastatic biliary tract cancer received GEMFUFOL regimen as the first- line treatment. The mean follow-up was 22.1 months (95%CI, 12.5-31.8). One patient (3.4%) achieved complete response, 5 (17.2%) had partial response, and 4 (13.8%) had stable disease. The median progression-free survival was 3.3 months (95%CI, 2.9-3.7), and the median overall survival was 8.8 months (95%CI, 3.5-14). The 1-year and 2-year survival rates were 58.6% and 30%, respectively. Grade 3 and 4 toxicity included neutropenia in 4 patients (13.7%), thrombocytopenia in 2 (6.8%), anemia in 2 (6.8%), and alopecia in 1 (3.4%). Two patients (6.8%) developed febrile neutropenia. A dose reduction was achieved in 8 patients (27.6%) while 5 patients had extended-interval dosage (17.2%) for toxicity. CONCLUSIONS: The GEMFUFOL chemotherapy regimen was generally efficacious and tolerable as a first-line treatment of metastatic biliary tract cancer.

CD40 expression in pancreatic cancer.

BACKGROUND: CD40, a tumor necrosis factor receptor family member, is expressed in a variety of cell types. This widespread expression suggests that CD40 may play an important role in normal physiology and disease pathogenesis. The objective of the current study was to investigate the expression of CD40, and its association with clinicopathological features and survival in patients with pancreatic ductal adenocarcinoma. METHODOLOGY: CD40 expression was assessed in 53 pancreatic ductal adenocarcinoma surgical specimens by immunohistochemistry, and expression was correlated with patient clinicopathological parameters and outcome. RESULTS: Among 53 pancreatic cancer specimens, CD40 expression was detected in 13 specimens (24.5%), and peritumoral lymphocytes were present in 45 specimens (84.9%). Patients with CD40-positive tumors exhibited prolonged median disease-free survival (DFS) compared with patients with CD40-negative tumors (15.60 +/- 3.87 versus 10.03 +/- 1.92); however, this was not significant (p = 0.845). Patients with peritumoral lymphocytic reaction exhibited prolonged median DFS compared with patients without peritumoral lymphocytes (10.96 +/- 1.40 vs. 7.60 +/- 0.47); however, this was not significant (p = 0.624). Patients with peritumoral lymphocytic reaction exhibited higher median overall survival compared with patients without peritumoral lymphocytes (15.20 +/- 1.78 vs. 10.13 +/- 1.39); however, again this was not significant (p = 0.100). CONCLUSIONS: These results suggest that CD40 expression on pancreatic cancer cells and peritumoral lymphocytic reaction may serve as prognostic markers.

Bimonthly regimen of high-dose leucovorin, infusional 5-fluorouracil, docetaxel, and cisplatin (modified DCF) in advanced gastric adenocarcinoma.

BACKGROUND: The combination of docetaxel, cisplatin, and 5-fluorouracil (DCF) is an effective but highly toxic regimen for the treatment of advanced gastric cancer. To improve tolerability while maintaining the efficacy of the DCF regimen, we developed a modified DCF regimen including an infusional 5-fluorouracil administration according to the de Gramont regimen. METHODS: In this study, 70 patients with advanced gastric cancer were treated. Each 2-week cycle consisted of docetaxel (60 mg/m(2)), cisplatin (50 mg/m(2)), a 5-fluorouracil (400 mg/m(2)) i.v. bolus, and 5-fluorouracil (2,400 mg/m(2)) i.v. over 46 h plus leucovorin (400 mg/m(2)) i.v. over 2 h. RESULTS: The median progression-free survival and overall survival were 9.0 months (95% CI, 7.1-10.9) and 10.8 months (95% CI, 7.4-14.2), respectively; the 1-year and 2-year overall survival rates were 46.3 and 18.4%, respectively. Twenty-nine (41.4%) partial responses, 19 (27.1%) stable disease, and 22 (31.4%) progression of disease were observed. Grade 3-4 toxicities included neutropenia (37.1%), febrile neutropenia (15.7%), thrombocytopenia (10.0%), anemia (8.6%), nausea and vomiting (10.0%), stomatitis (5.7%), infection (8.6%), and diarrhea (2.9%). CONCLUSIONS: Our results show that a de Gramont-based DCF regimen may have tolerable toxicities and be an effective and convenient palliative treatment for advanced gastric cancer.

Long term survivors with metastatic pancreatic cancer treated with gemcitabine alone or plus cisplatin: a retrospective analysis of an Anatolian Society of Medical Oncology multicenter study.

BACKGROUND: The majority of patients with pancreatic cancer present with advanced disease. Systemic chemotherapy has limited impact on overall survival (OS) so that eligible patients should be selected carefully. The aim of this study was to analyze prognostic factors for survival in Turkish advanced pancreatic cancer patients who survived more than one year from the diagnosis of recurrent and/or metastatic disease and receiving gemcitabine (Gem) alone or gemcitabine plus cisplatin (GemCis). METHODS: This retrospective evaluation was performed for patients who survived more than one year from the diagnosis of recurrent and/or metastatic disease and who received gemcitabine between December 2005 and August 2011. Twenty-seven potential prognostic variables were chosen for univariate and multivariate analyses to identify prognostic factors associated with survival. RESULTS: Among the 27 variables in univariate analysis, three were identified to have prognostic significance: sex (p=0.04), peritoneal dissemination (p=0.02) and serum creatinine level (p=0.05). Multivariate analysis by Cox proportional hazard model showed only peritoneal dissemination to be an independent prognostic factor for survival. CONCLUSION: In conclusion, peritoneal metastasis was identified as an important prognostic factor in metastatic pancreatic cancer patients who survived more than one year from the diagnosis of recurrent and/ or metastatic disease and receiving Gem or GemCis. The findings should facilitate pretreatment prediction of survival and can be used for selecting patients for treatment.

Bimonthly regimen of high-dose leucovorin, infusional 5-fluorouracil, epirubicin and cisplatin (modified ECF) as adjuvant chemotherapy in resected gastric adenocarcinoma.

BACKGROUND: The administration of the de Gramont regimen in combination with cisplatin and epirubicin (modified ECF) has previously been reported as a treatment for advanced gastric cancer, but here we report this regimen combination in an adjuvant setting for the first time. METHODS: Forty-eight patients with curatively resected gastric cancer were treated. Each 2-week cycle consisted of epirubicin (50 mg/m(2)), cisplatin (50 mg/m(2)), 5-fluorouracil (5-FU) IV bolus (400 mg/m(2)) and 5-FU IV (2,400 mg/m(2)) over 46 h plus leucovorin IV (400 mg/m(2)) over 2 h. Postoperative chemoradiotherapy was also administered to the patients when indicated. We retrospectively reviewed the patients who were treated with modified ECF. RESULTS: The median disease-free survival (DFS) was 40.7 months and the 1-, 3- and 5-year DFS rates were 78.5, 55.7 and 44.6%, respectively. The most common grade 3-4 toxicities were hematological and gastrointestinal. CONCLUSION: A modified ECF regimen may be an effective and convenient treatment with tolerable toxicities for the adjuvant treatment of gastric cancer. It may provide an alternative regimen to the standard ECF when a continuous ambulatory infusion pump is not feasible or not preferred by the patient.

Clinical and electrocardiography changes in patients treated with capecitabine.

BACKGROUND: We aimed to identify the incidence of cardiac events with capecitabine treatment. METHODS: The study included 52 patients (median age 59 years) with cancer treated at our Medical Oncology Clinic between 2009 and 2010. Cardiac events from capecitabine treatment were classified into 4 groups: cardiac symptoms, physical signs, electrocardiography (ECG) findings, and severe adverse cardiac effects. RESULTS: The patients received either single-agent capecitabine or a combination chemotherapy including capecitabine. After initiation of capecitabine, 18 patients (34.6%) had new onset cardiovascular symptoms, 6 (11.5%) had new onset physical signs and 17 (32.6%) had new onset ECG findings. New onset ECG findings included prolonged corrected QT interval (n = 10, 19.2%) and prolonged PR interval (n = 3, 5.8%). Severe adverse capecitabine-induced cardiac side effects were observed in 5.8% of the patients, but none of the patients had myocardial infarction or died. CONCLUSION: Cardiac events are not rare during capecitebine treatment and patients should be followed closely to avoid cardiac morbidity and mortality.
