RESUMO

Hepatocellular carcinoma (HCC), the most prevalent liver tumor, is usually linked with chronic liver diseases, particularly cirrhosis. As per the 2020 statistics, this cancer ranks 6th in the list of most common cancers worldwide and is the third primary source of cancer-related deaths. Asia holds the record for the highest occurrence of HCC. HCC is found three times more frequently in men than in women. The primary risk factors for HCC include chronic viral infections, excessive alcohol intake, steatotic liver disease conditions, as well as genetic and family predispositions. Roughly 40-50% of patients are identified in the late stages of the disease. Recently, there have been significant advancements in the treatment methods for advanced HCC. The selection of treatment for HCC hinges on the stage of the disease and the patient's medical status. Factors such as pre-existing liver conditions, etiology, portal hypertension, and portal vein thrombosis need critical evaluation, monitoring, and appropriate treatment. Depending on the patient and the characteristics of the disease, liver resection, ablation, or transplantation may be deemed potentially curative. For inoperable lesions, arterially directed therapy might be an option, or systemic treatment might be deemed more suitable. In specific cases, the recommendation might extend to external beam radiation therapy. For all individuals, a comprehensive, multidisciplinary approach should be adopted when considering HCC treatment options. The main treatment strategies for advanced HCC patients are typically combination treatments such as immunotherapy and anti-VEGFR inhibitor, or a combination of immunotherapy and immunotherapy where appropriate, as a first-line treatment. Furthermore, some TKIs and immune checkpoint inhibitors may be used as single agents in cases where patients are not fit for the combination therapies. As second-line treatments, some treatment agents have been reported and can be considered.

RESUMO

AIMS: To evaluate patient profile for epidemiological and clinicopathological characteristics and potential risk/prognostic factors in newly diagnosed hepatocellular carcinoma (HCC) patients across Turkey. METHODS: A total of 547 patients (mean (SD) age 62.6 (10.3) years, 81.9% were males) were included in this registry study. Data on patient characteristics, etiologies of HCC, laboratory values, and tumor characteristics and stages were recorded at study enrollment. RESULTS: HBV infection (68.2%) was the leading etiology, followed by HCV infection (17.2%), HDV infection (5.5%), alcohol (6.4%), and NAFLD (3.5%), as the major etiologies. Considering that 51.6% of the patients had >5 cm HCC, 44% were Child-Pugh B/C and 57% were BCLC B-D, it appears that a significant group of HCC patients were diagnosed at advanced stages. Of 540 patients, 271 (50.2%) were referred or applied with the diagnosis of HCC. Patients with HCC at presentation had larger tumor size (median (min-max) 6.6 (0-30) vs. 4.8 (0-90) cm, P < .001) and more advanced BCLC stage (Stage C-D in 40.8% vs. 26.4%, respectively, P = .005), compared to patients who were diagnosed during follow-up. CONCLUSIONS: Our findings revealed that HBV infection was the leading etiology and a moderate-to-advanced disease was evident in more than half of patients at the time of diagnosis. HCC patients diagnosed at follow-up had smaller tumor size and earlier BCLC stage.

RESUMO

OBJECTIVES: Regorafenib improved overall survival in patients with metastatic colorectal cancer (mCRC) refractory to standard therapies in two randomised, phase III trials, but has not been evaluated in Turkey. REGARD evaluated the safety and efficacy of regorafenib in Turkish patients with treatment-refractory mCRC. DESIGN: Open-label, single-arm, phase IIIb study conducted between July 2013 and April 2015. SETTING: 11 tertiary centres in Turkey. PARTICIPANTS: Eligible patients were adults with mCRC who had disease progression within 3 months after receiving their last dose of approved standard therapies and who had an Eastern Cooperative Oncology Group performance status ≤1. Patients were excluded if they had previously received regorafenib. Of 139 patients screened, 100 were treated and completed the study, and all 100 were analysed. Fifty-eight per cent were male. INTERVENTIONS: Patients received oral regorafenib, 160 mg once daily, for the first 3 weeks of each 4-week cycle until disease progression, death or unacceptable toxicity. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary endpoint was safety, assessed by incidence of treatment-emergent adverse events (TEAEs). Progression-free survival (PFS) per investigator was the primary efficacy endpoint. There were no secondary endpoints. RESULTS: The median treatment duration was 2.5 months (range 0.1 to 20.6). Ninety-six per cent of patients had at least one TEAE and 77% had a grade ≥3 TEAE. The most common grade ≥3 regorafenib-related TEAEs were hypophosphataemia (11%), fatigue (8%), hyperbilirubinaemia (6%), hand-foot skin reaction (5%), hypertension (5%), anorexia (5%) and increased alanine aminotransferase (5%). TEAEs led to dose reduction in 30% of patients. Regorafenib-related TEAEs led to treatment discontinuation in 17% of patients. Median PFS was 3.1 months (95% CI 2.9 to 3.8). CONCLUSION: The regorafenib safety profile and PFS in REGARD were consistent with the results of previous trials of regorafenib in mCRC. Regorafenib is an option for patients in Turkey with treatment-refractory mCRC. TRIAL REGISTRATION NUMBER: NCT01853319, ClinicalTrials.gov.

RESUMO

Tumour markers are widely used for the diagnosis, staging and monitoring of colorectal cancer (CRC) patients in clinical practice. Carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) are the most frequently used biomarkers in CRC patients. A number of studies have recently investigated the presence of human epididymis protein 4 (HE4) overexpression in certain cancer types. Its significance in ovarian and endometrial cancer has been well-demonstrated. The aim of the present study was to evaluate the significance of serum HE4 levels in CRC patients. A total of 46 newly diagnosed CRC patients and 36 age- and gender-matched healthy subjects were included in the study. The concentrations of CEA and CA19-9 were also determined and compared according to HE4 levels. HE4 positivity was determined in 13 of the 46 cases (28.3%) in the CRC group, but no HE4-positive subjects were identified in the control group (0%; P=0.009). The area under the receiver operating characteristic curve for HE4 positivity was 0.641 (95% CI: 0.523-0.760). HE4 was statistically significantly positive in patients with stage III-IV disease and in those with high CA 19-9 levels (all P<0.01). To the best of our knowledge, this is the first study to investigate HE4 expression in CRC patients, and the findings suggest that it may be a useful biomarker, particularly in stage III-IV patients.

RESUMO

OBJECTIVE: To investigate the effect of immunosuppressive anticancer therapy on titre levels of anti-hepatitis B surface antibodies (anti-HBs) in hepatitis B surface antigen (HBsAg) negative and anti-HBs positive patients with haematological malignancies or solid tumours. METHODS: This retrospective study reviewed the medical records of patients with haematological malignancies or solid tumours. Pretreatment HBsAg negative and anti-HBs positive patients were included in the analysis. Anti-hepatitis B core antibody status was used to evaluate vaccinated patients and those with resolved HBV infections. RESULTS: The medical records of 237 patients were reviewed retrospectively. The median anti-HBs titre decreased significantly after anticancer therapy compared with the pretreatment median anti-HBs titre in all patients (71 mIU/ml versus 57 mIU/ml). Anti-HBs titre decreased significantly in patients with haematological malignancies (70 mIU/m versus 37 mIU/ml) and in patients administered rituximab-based chemotherapy (67 mIU/ml versus 33 mIU/ml) following chemotherapy, whereas there was no significant change in patients with solid tumours. After chemotherapy, patients with low pretreatment anti-HBs titres (<100 mIU/ml) were more likely to become seronegative (<10 mIU/ml). CONCLUSION: High levels of anti-HBs may have a protective effect against the reactivation of HBV especially in patients with haematological malignancies who received immunosuppressive anticancer therapy.

RESUMO

The present study aimed to analyze the clinical significance of epithelial membrane protein 1 (EMP1) expression in ovarian serous tumors. A total of 84 cases of ovarian serous tumor (50 patients with malignant ovarian serous tumors and 34 patients with borderline and benign serous tumors) were retrospectively analyzed. Differences in the expression levels of EMP1 between the malignant and non-malignant tumor groups were evaluated by immunohistochemical staining. In addition, the association between EMP1 expression and prognostic factors in malignant ovarian serous tumors was investigated. The expression levels of EMP1 were significantly reduced in all the 50 malignant ovarian serous tumors, compared with the 34 non-malignant ovarian serous tumors (P<0.000). Reduced expression of EMP1 was correlated with high grade (P=0.009) and stage (P<0.000) of malignant tumors. EMP1 expression was not observed to be correlated with any other investigated parameters, including surgery, type of operation and chemotherapy response (P>0.005). These results indicated that EMP1 may have a significant role as a negative regulator in ovarian serous tumors, and reduced EMP1 expression in serous tumors may be associated with increased disease severity.

RESUMO

Thyroid extracts were first used to treat patients with metastatic breast cancer over a century ago. Since then, a number of studies have investigated the association between thyroid disorders and breast cancer. The presence of antibodies to thyroid peroxidase (TPOab) was recently reported to be associated with improved outcome in these patients. The aim of the present study was to evaluate the association between TPOab positivity and clinicopathological characteristics in breast cancer patients. The study included 318 newly diagnosed cases of breast cancer treated at Ondokuz Mayis University Hospital, Samsun, Turkey, between 2008 and 2012. Serum thyroid-stimulating hormone, free triiodothyronine and free thyroxine levels were measured at the time of diagnosis. Of the 318 patients, 253 were considered to be TPOab-negative (TPOab ≤34 IU/ml) and 65 TPOab-positive (TPOab >34 IU/ml). No cases with distant metastases were found in the TPOab-positive group. However, 20 (7.9%) of the 253 patients displayed distant metastases in the TPOab-negative group (P=0.01). Therefore, TPOab positivity was found to be associated with a lower incidence of metastasis in breast cancer patients.

RESUMO

PURPOSE: Colorectal cancer (CRC) survivors are currently living longer due to better therapies but they also need to maintain their quality of life (QoL). QoL is increasingly being used as primary outcome measure in clinical studies. This study was designed to gain knowledge about QoL during chemotherapy across different lines and different regimens. METHODS: The study comprised 101 CRC out patients receiving chemotherapy who completed the EORTC QLQ-C30 questionnaire. The Shapiro-Wilk, Kruskal-Wallis, and Mann-Whitney U tests were used for statistical analyses. RESULTS: The demographics of the patients were evaluated for QoL. Prior surgery, prior radiotherapy, working status, stage, comorbidity and sex had no effect on global health status in CRC patients, although some other demographics such as education, monthly income, age and type of chemotherapy regimen did have an effect on global health status. Role functioning was worse in older than in younger ones (p<0.05). Adjuvant chemotherapy did not affect the QoL scores negatively but palliative chemotherapy negatively affected the cognitive function, appetite loss and nausea/vomiting scores (p<0.05). According to chemotherapy regimen, the best QoL was observed with adjuvant FUFA regimen. In the palliative setting FOLFOX/Bevacizumab was associated with the best QoL scores whereas FOLFIRI/Cetuximab were associated with the worst QoL scores. CONCLUSIONS: Palliative chemotherapy maintained QoL irrespective of the chemotherapy line in metastatic CRC (mCRC) patients. Some demographics affect QoL and different chemotherapy regimens showed different QoL scores.

RESUMO

BACKGROUND: Red cell distribution width (RDW) is a routinely examined parameter with the complete blood count. In recent studies, RDW levels have been associated with cardiovascular, liver and renal diseases and solid tumors. The aim of this study was to evaluate the alterations of RDW levels in benign and malignant causes of postmenopausal bleeding and to investigate the association of RDW levels with clinicopathological parameters of endometrial cancer (EC) patients. METHODS: A retrospective study was made of a total of 884 females who were admitted to hospital for postmenopausal bleeding between May 2009 and December 2013. After inclusion and exclusion criteria were applied, 222 patients remained. Complete blood count data was obtained from the recorded computerized database. After pathological evaluation, the patients were divided into two groups, benign and malignant (EC). RESULTS: The EC group (n=113) had significantly higher RDW levels compared to the benign group (14.78±2.02 vs. 13.88±1.05; p=0.000). Grade II and above EC patients had higher levels of RDW than Grade I patients (15.2±2.3 vs. 14.1±1.00; p=0.005). Correlation analyses also revealed a negative correlation between RDW and hemoglobin levels (p=0.000), RDW and mean corpuscular volume (p=0.000), RDW and lymphocyte count (p=0.035) but a positive correlation between RDW and platelet to lymphocyte ratio (p=0.030). CONCLUSIONS: The results of the current study revealed the potential predicitve role of RDW in patients with postmenopausal bleeding. Significant associations were also determined between RDW and clinicopathological characteristics in EC patients.

RESUMO

Advanced gastric cancer has a poor prognosis, and only chemotherapy improves survival. Further chemotherapy after progression is controversial. Eastern Cooperative Oncology Group performance status is an important indicator for new chemotherapy decision. Complete response (CR) after recurrent disease is very rare, but could occur in some cases with chemotherapy. The 68-year-old male received chemotherapy for metastatic gastric adenocarcinoma. He received epirubicin, cisplatin and fluorouracil in the first line, capecitabine in the second line and cisplatin-capecitabine in the third line. CR was observed after third-line chemotherapy with four courses. Mediastinal and abdominal metastases were completely resolved. We decided to report this patient because it is very unusual to achieve CR in a patient in whom the best supportive care might be reasonable.

RESUMO

OBJECTIVE: Increased risk for non-Hodgkin lymphoma (NHL) is associated with infections and environmental agents. We hypothesized that these factors chronically trigger the T helper-2 (Th2) pathway and result in lymphoma. We investigated the role of the Th2 pathway by exploring the relationships between components of the Th2 pathway, interleukin (IL)-10, IL-4, immunoglobulin E (IgE), and eosinophils, and prognostic markers of NHL. MATERIALS AND METHODS: Thirty-one NHL patients and 27 healthy controls were enrolled. IL-10, IL-4, IgE, and eosinophils were measured. IL-4 and IL-10 were analyzed with the enzyme amplified sensitivity immunoassay method. RESULTS: High IL-10 levels were correlated with several poor prognostic features, short early survival, and lymphopenia. There was a positive correlation between albumin and IL-4 levels and a negative correlation between IL-10 and albumin. There was no relationship related with eosinophils and IgE. We found remnant increased IL-4, which could be a clue for the triggering of the Th2 pathway in the background. CONCLUSION: There is a need for differently designed studies to detect the place of the Th2 pathway in NHL.

RESUMO

OBJECTIVES: Advanced gastric cancer (AGC) patients have a poor prognosis. The best benefit of chemotherapy is usually achieved by first line setting. Very few studies have compared combination regimens. This study was designed to compare two combination regimens. METHODS: Patients with advanced gastric cancer receiving first line chemotherapy were retrospectively collected, and divided into two groups, receiving DCF (docetaxel, cisplatin and fluorouracil) or ECF (epirubicin, cisplatin and fluorouracil) regimens. Data were collected for the retrospective analysis in a single center. RESULTS: Eighty-six patients were eligible for analysis. Median overall survival (OS) was 10.0 months in the ECF group and 11.0 months in the DCF group (p=0.31). Median progression free survival (PFS) for ECF and DCF was equal at 6.0 months. Second line chemotherapy were administered in more than one third of patients. Both regimens had similar toxicity. CONCLUSIONS: This is the first study investigating the outcomes of gastric cancer chemotherapy in this region. ECF and DCF regimens have similar efficacy and a similar tolerability profile for first line treatment of advanced gastric cancer. The decision of the first line chemotherapy in advanced gastric cancer could be improved with patient selection according to clinical parameters and molecular markers.

RESUMO

PURPOSE: This study aimed to report the practice of managing breast cancer with bone metastasis in Turkey and to determine the adherence to the British Association of Surgical Oncology (BASO) guidelines. METHODS: This multicenter, cross-sectional epidemiological survey was conducted in 38 centers across Turkey. Data from 1,026 breast cancer patients with bone metastases (mean age 54.0 ± 11.9 years) were analyzed. RESULTS: Over 30 % of patients had a diagnosis of metastatic breast cancer (stage IV) at the time of primary diagnosis. The imaging modalities used for diagnosing bone metastases were bone scintigraphy (57.8 %), radiography (22.8 %), and bone survey (4.4 %). Tumor markers were detected in 94.9 %, and markers of bone metabolism were measured in 90.4 % of patients. A total of 3.5 % of patients underwent surgery for bone metastasis, 26.4 % underwent palliative chemotherapy (most commonly docetaxel + capecitabine), and 56.5 % endured radiotherapy. Most patients (96 %) also received bisphosphonate. Radiography, bone scintigraphy, and CT were the main imaging tools used for postoperative follow-up of bone metastasis. Our results were >95 % in line with the BASO guidelines for the management of bone metastasis, except that interventional procedures, such as biopsy, were applied less frequently in our survey. CONCLUSIONS: The diagnosis and management practices of breast cancer with bone metastasis in Turkey were generally compatible with international guidelines. However, the awareness and knowledge of physicians on the current guidelines should be increased, and equipment for the appropriate interventional procedures should be provided in every clinic to obtain optimal and standard management of bone metastases.

RESUMO

BACKGROUND: Lung cancer (LC) is still the primary cause of cancer deaths worldwide, and late diagnosis is a major obstacle to improving lung cancer outcomes. Recently, elevated preoperative or pretreatment neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and mean platelet volume (MPV) detected in peripheral blood were identified as independent prognostic factors associated with poor survival with various cancers, including colon cancer, esophageal cancer, gastric cancer and breast cancer. OBJECTIVE: The aim of this study was to examine whether MPV, NLR and PLR could be useful inflammatory markers to differentiate lung cancer patients from healthy controls. An investigation was also made of the relationship between these markers and other prognostic factors and histopathological subgroups. MATERIALS AND METHODS: Retrospectively eighty-one lung cancer patients and 81 age-sexes matched healthy subjects included into the study. Patients with hypertension, hematological and renal disease, heart failure, chronic infection, hepatic disorder and other cancer were excluded from the study. The preoperative or pretreatment blood count data was obtained from the recorded computerized database. RESULTS: NLR and PLR values were significantly higher in the LC patients compared to the healthy subjects.( NLR: 4.42 vs 2.45 p=0.001, PLR: 245.1 vs 148.2 p=0.002) MPV values were similar in both groups (7.7 vs 7.8). No statistically significant relationship was determined between these markers (MPV, NLR and PLR) and histopathological subgroups and TNM stages. CONCLUSIONS: NLR and PLR can be useful biomarkers in LC patients before treatment. Larger prospective studies are required to confirm these findings.

RESUMO

PURPOSE: Nausea and vomiting are among the major problems occurring during and after the chemotherapy treatments of cancer patients. The recently developed 5-HT(3) antagonists have proved much more effective than former agents. Several studies have shown that these agents cause certain ECG changes. We aimed to evaluate the ECG changes caused by palonosetron, one of the new 5-HT(3) antagonists. METHODS: Our study includes a total of 50 patients diagnosed with solid-organ tumors receiving chemotherapy. The patients were applied 12-lead ECG before palonosetron infusion. Afterwards, subsequent ECGs were applied on the 30th, 60th, and 90th minutes following the infusion of palonosetron. Arterial blood pressure was measured before and after the infusion. PR, QRS, QT, QTmax, QTmin, QTd, Pmax, Pmin, Pd, QTc, QTcmax, QTcmin, and QTcd values were evaluated for each ECG. RESULTS: We did not detect significant correlations between the systolic and diastolic blood pressures before and after (30 min) palonosetron infusion (p > 0.05). However, there was a statistically significant decrease in heart rate (p = 0.000). The evaluation of ECG findings revealed that there was a significant prolongation in PR distance, as shown by the comparisons of 0 min with 30, 60, and 90 min. On the other hand, there was no significant difference in QRS, QT, QTmax, QTmin, QTd, Pmax, Pmin, Pd, QTc, QTcmax, QTcmin, and QTcd values (p > 0.05). CONCLUSION: In this study, we revealed that palonosetron did not cause any severe rhythmic disorders or symptomatic ECG changes. We concluded that it could be safe to administer palonosetron antiemetically.

RESUMO

UNLABELLED: Plakophilins (PKP) are desmosomal plague proteins, which belong to the p120ctn subfamily of armadillo repeat containing proteins. We aimed to analyze the role of plakophilins in breast cancer and its clinical progress. We have performed immunohistochemical study of the PKP1,2,3 in breast carcinoma. The study included 108 patients with breast cancer and 26 age- and sex-matched healthy controls. We investigated the associations between staining intensity and some clinicopathologic features like tumor size, axillary node status, stage, lymphovascular invasion, perineural invasion, grade, hormone receptor status, and c-erb B2. The mean age of patients was 46 years (22-78). In breast cancer, compared with normal tissue, PKP1 and PKP2 expressions were indifferent (P > 0.05), but PKP3 expression was significantly increased in breast cancer (P = 0.0014). Although PKP1 and PKP2 expression levels were not correlated with clinicopathological parameters, increased PKP3 expression was positively correlated with node positivity and grade (P = 0.000, P = 0.000). CONCLUSION: Overexpressed PKP3 is likely to be an essential contributor to a growth-promoting pathway and to aggressive features of breast cancer.

BACKGROUND: The importance of cell-cell junction proteins (including armadillo proteins) in tumor biology is known, but limited with regard to plakophilins. We explored the relationship between plakophilins (PKP1, PKP2, PKP3) to gastric cancer via immunohistochemical techniques. METHODS: We compared the immunohistochemistry of PKPs in 34 gastric adenocarcinomas and 20 normal gastric tissues. RESULTS: In gastric cancer, PKP1 expression was unchanged but PKP2 and PKP3 were significantly decreased as compared to normal controls. There was no observable clinical association with PKP1 or PKP2 expression; however, low PKP3 level and poor prognosis appeared to correlate with regards to node number and tumor stage. The mean disease-free survival (DFS) was 38 ± 3 months (range: 32 - 44) and mean overall survival (OS) 42 ± 4 months (range: 38 - 50). Decreased PKP2 appeared to negatively impact DFS. CONCLUSION: Decreased PKP2 and PKP3 may be early prognostic markers and loss of PKP3 expression during gastric carcinoma progression may indicate an invasive phenotype.

RESUMO

PURPOSE: In this study, we have examined the correlation between colorectal cancer (CRC) and serum adiponectin and resistin levels, body mass index and insulin resistance. METHODS: The relation between serum adiponectin and resistin levels, obesity and insulin resistance in 36 CRC patients and 37 controls was examined. RESULTS: Insulin and homeostasis model assessment insulin resistance index (HOMA-IR) levels were higher, and adiponectin levels were significantly decreased in patients versus controls, whereas, resistin levels were significantly increased. A negative correlation between adiponectin, HOMA-IR, and insulin and a positive correlation between HOMA-IR, insulin, and stage were detected. There was no correlation between the stage and resistin. Adiponectin level negatively correlated with the stage. Adiponectin and resistin could play a role in colon cancer carcinogenesis, and adiponectin could be responsible for poor prognosis in colorectal cancer.

RESUMO

Cancer affects not only the individuals with cancer, but also their families considerably. The aim of this study was to determine the sociodemographic characteristics and home care needs of caregivers of cancer patients receiving chemotherapy and evaluate their quality of life scores. A total of 126 primary caregivers of patients receiving chemotherapy who were eligible for inclusion criteria participated in the study. Data were collected using a questionnaire that included sociodemographic questions for both patients and caregivers and the World Health Organization Quality of Life-Short Form, Turkish Version (WHOQOL-BREF(TR)) for the caregivers. The mean domain scores of WHOQOL-BREF(TR) were 15.3 +/- 2.8 for physical, 14.6 +/- 2.8 for psychological, 14.4 +/- 3.3 for social, 13.7 +/- 2.8 for environment, and 14 +/- 2.5 for national environment domains. Caregivers were, on average, younger than the patients and the mean age of the caregivers was 45 years. Around 70% of caregivers were living with the patients, 60.3% of caregivers shared the care-giving process with someone else, and his/her children supported in care-giving activities in 20.6%. According to caregivers, patients needed assistance for one or more daily living activities. Caregivers' higher age, unemployment status, female gender, low education level, their own diagnosed health problems, care duration above 18 months, and having difficulties to continue social activities had negative effects on their quality of life. Cancer patients' families are also affected from cancer. We may suggest that including caregivers in the context of home care and universalizing home care programs can reduce caregivers' burden.

RESUMO

Primary mucinous cystadenocarcinoma (MCA) of the breast was first described by Koenig and Tavassoli in 1998. To our knowledge, only 9 cases of MCA of the breast have been reported. The optimal treatment of MCA could not be defined yet. This article aims to increase the knowledge about this rare variant of breast cancer and to review the literature.
