RESUMO

INTRODUCTION: The aim of this study is to show the relationship between the serum uric acid level measured at the time of diagnosis and the BRAF mutation status in the primary tumor tissue in patients with metastatic colorectal cancer. METHODS: In this retrospective cross-sectional study, 264 patients (64% male) whose serum uric acid level was measured at the time of diagnosis and whose BRAF mutation status in the primary tumor was determined were included. RESULTS: The BRAF mutation rate was 14% (n=37). The median serum uric acid levels of all patients were 6.9 mg/dL (25%, 75% percentile range 3.7, 8.2). The cut-off value for serum uric acid level was calculated as 6.6 mg/dL. Sensitivity and specificity for BRAF mutated patients were 84% and 27%, respectively. These rates were calculated as 85% and 70% in BRAF mutated patients aged 65 and over, respectively. There was a significant correlation between BRAF mutation and high serum uric acid level, female gender, tumor located in the ascending colon, and multiple metastatic sites. The independent factors affecting BRAF mutation were age 65 and over, tumor located in the ascending colon, and high serum uric acid level. CONCLUSION: As a result, we concluded that high serum uric acid level measured at the time of diagnosis in metastatic colorectal cancer is an accessible and economical biomarker that can predict BRAF mutation in patients aged 65 and over.

RESUMO

PURPOSE: This study evaluated the efficacy and safety of everolimus (EVE) plus exemestane (EXE) in hormone-receptor positive (HR+), human epidermal growth factor receptor-2-negative (HER2-) metastatic breast cancer (MBC) patients in real-life settings. METHODS: Overall, 204 HR+, HER2- MBC patients treated with EVE + EXE after progressing following prior endocrine treatment were included. Overall survival (OS) and progression-free survival (PFS) and safety data were analyzed. RESULTS: The objective response rate, median PFS, and median OS were 33.4%, 8.9 months, and 23.4 months, respectively. Multivariate analysis revealed that negative progesterone receptor status was a significant determinant of poor treatment response (p = 0.035) and PFS (p = 0.024). The presence of bone-only metastasis was associated with better treatment response (p = 0.002), PFS (p < 0.001), and OS (p = 0.001). CONCLUSION: We confirmed the favorable efficacy and safety profile of EVE + EXE for HR+, HER - MBC patients.

RESUMO

Sarcomas probably develop after malignant transformation of embryonic mesenchymal cells and have broad spectrum histopathologically since they can develop from striated skeletal muscle and smooth muscle, fat and fibrous tissue, bone, cartilage and other mesenchymal tissues. The most common histological subtypes of soft tissue sarcoma in adults are: liposarcoma, leiomyosarcoma, poorly differentiated pleomorphic sarcoma, and gastrointestinal stromal tumor. Molecular and genetic studies of soft tissue sarcomas, which are considered as heterogeneous groups in terms of their molecular and clinical characteristics, are still an important area of ​​interest The heterogeneity of the molecular and genetic alterations of these malignancies, which are mostly treated with surgery and chemotherapy, also offers hope to the researchers in terms of treatment targets. In this article, molecular biologic features of the soft tissue sarcomas including liposarcoma, rhabdomyosarcoma, leiomyosarcoma, synovial sarcoma, and angiosarcoma are discussed in the light of recent developments in molecular biology, targeted therapies and immunotherapy.

RESUMO

Chemotherapy-induced nausea and vomiting (CINV) may be linked to the psychological status of cancer patients. Therefore, the authors aimed to better understand the underlying risk factors for CINV using the Brief Illness Perception Questionnaire. A total of 238 patients were recruited during three cycles of chemotherapy. Patient, disease and treatment characteristics were noted at the onset of chemotherapy. The Brief Illness Perception Questionnaire was administered face-to-face prior to chemotherapy. The relationship between illness perceptions and CINV was analyzed using Spearman's rank correlation. Positive illness perception parameters, including personal and treatment control, were negatively correlated, whereas negative illness perception parameters, including consequences, timeline, identity, concern and emotions, were positively correlated with CINV after adjusting for age, sex and emetogenic potential of chemotherapy (p < 0.001). Illness perception may be an underlying risk factor for CINV.

RESUMO

BACKGROUND: Atezolizumab (ATZ) has demonstrated antitumor activity and manageable safety in previous studies of patients with metastatic platinum-resistant urothelial carcinoma. However, the response rate of Atezolizumab was modest. In the current study, we evaluated the pretreatment prognostic factors for overall survival in patients with metastatic urothelial carcinoma who have progressed after first-line chemotherapy in the Expanded-Access Program of Atezolizumab. PATIENTS AND METHODS: In this study, we present a retrospective analysis of 113 patients with urothelial cancer treated with ATZ after progression on first-line chemotherapy. Data of the patients was obtained from patient files and hospital records. Eligible patients included metastatic urothelial carcinoma patients treated with at least one course of ATZ. Univariate analysis was used to identify clinical and laboratory factors that significantly impact OS. Variables were retained for multivariate analysis if they had a statistical relationship with OS (p < 0.1), and then included a final model of p < 0.05. RESULTS: The median follow-up duration was 23.5 months. Of the patients, 98 (86.7%) were male and 13.3% were female. The median age was 65 years of age (37-86). In univariate analysis, primary tumor location in the upper tract, increasing absolute neutrophil count (ANC), increasing absolute lymphocyte count, neutrophil-to-lymphocyte ratio (NLR) > 3, liver metastases, baseline creatinine clearance less (GFR) than 60 ml/min, Eastern Cooperative Oncology Group (ECOG) performance status (1 ≥), and hemoglobin levels below 10 mg/dl were all the significantly associated with OS. Three of the five adverse prognostic factors according to the Bellmunt criteria were independent of short survival: liver metastases HR 3.105; 95% CI 1.673-5.761; p < (0.001), ECOG PS (1 ≥) HR 2.184; 95% CI 1.120-4.256; p = 0.022, and Hemoglobin level below 10 mg/dl HR 2.680; 95% CI 1.558-4.608; p < (0.001). In addition, NLR > 3 hazard ratio [HR] 2.092; 95% CI 1.031-4.243; p = 0.041 and GFR less than 60 ml/min HR 1.829; 95% CI 1.1-3.041; p = 0.02, maintained a significant association with OS in multivariate analysis. CONCLUSIONS: This model confirms the Bellmunt model with the addition of NLR > 3 and GFR less than 60 ml/min and can be associated with clinical trials that use immunotherapy in patients with bladder cancer.

RESUMO

INTRODUCTION: Lung cancer still ranks first among the most common and most lethal cancers today. The most common subtype is non-small cell lung cancer, and in this group, adenocarcinoma has the worst prognosis. EGFR, ROS1 and ALK-EML4 gene fusion mutations are common in non-small cell lung cancer. CASE REPORT: A 62-year-old non-smoker patient applied in February 2014 for purulent sputum and pain in the chest. Computed tomography revealed a 39x33 mm mass in the right hilum, multiple parenchymal nodules in the bilateral lung and mediastinal multiple enlarged lymph nodes. The patient was admitted to the lung adenocarcinoma as a result of a biopsy from the mass in the hilum, and sarcoidosis was diagnosed by mediastinal lymph node biopsy. MANAGEMENT & OUTCOME: After 4 cycles of carboplatin-pemetrexed for the first line treatment, progression was detected. The patient did not have EGFR and ROS1 mutations. The patient with positive ALK fusion mutation started crizotinib treatment in July 2014. The patient's last response assessment was in March 2020, with 68-progression-free disease with crizotinib. No toxicity was observed except for Grade 1 weakness. No dose changes were made. The patient is still being followed up without brain metastasis under the treatment of crizotinib. DISCUSSION: In this article, we wanted to share our experience of crizotinib in a 68-months progression-free survival in a 62-years old non-smoking female patient with metastatic lung adenocarcinoma who is also diagnosed with sarcoidosis.

RESUMO

Background/aim: The aim of this study was to determine whether breast surgery changes body posture in patients with early-stage breast cancer. Materials and methods: Study variables include age, side and localization of the tumor in the breast, applied breast surgery, axillary interference, pathological tumor size, axillary lymph node metastasis, body mass index, bone density, adjuvant therapies, and histological type. Thoracic kyphosis angle due to the anatomically affected primary region to detect changes in body posture and Cobb's method were used to measure this. Results: There was a statistically significant difference in the mean Cobb's angle between the follow-up times of 57 patients (P < 0.001), with a cumulative increase in the Cobb's angle from baseline to the second year. As the age of the diagnosis progressed, the Cobb's angle increased significantly at 2 years when compared to baseline (r = 0,616, P < 0,001). In terms of baseline, the higher the BMI level in the 2nd year, the higher the Cobb's angle in the 2nd year as compared to the baseline (r = 0,529, P < 0,001). Conclusion: It was concluded that the increase in thoracic kyphosis in patients with breast cancer should be examined psychosocially. The study should be supported by a larger number of patients.

RESUMO

OBJECTIVE: Fear of cancer recurrence (FCR) is an important psychological trauma associated with reduction in the quality of life, disruptions in the level of adjustment, emotional distress and anxiety. The purpose of the study was to evaluate the impact of patient-physician relationship on FCR. METHODS: The study was designed as a multicentre survey study. The cancer survivors, who were under remission, were evaluated with structured questionnaires. Patient-physician relationship (PPR) scale in which higher scores indicate better relationship and FCR inventory was used. RESULTS: Between January and April 2019, 1,580 patients were evaluated. The median age was 57.0 (19-88), and 66% were female. There was high level of FCR scores in 51% of participants. There was a negative correlation between PPR and FCR scores (r = -.134, p < .001). In multivariate analysis, young age, female gender, history of metastasectomy and worse PPR were associated with high levels of FCR. CONCLUSION: It is the first data showing the adverse impact of worse PPR on FCR. The strategies to improve the PPR should be practised. In addition, the cancer survivors, who are under the risk of FCR, should be evaluated and managed.

RESUMO

INTRODUCTION: Metastasis to the gastrointestinal tract from lung cancer is very uncommon and is often asymptomatic. Although small bowel metastasis may commonly occur, metastases to the stomach and colon are uncommon. CASE REPORT: In this paper, we present a previously healthy 57-year-old male patient, a 60-packet per year smoker, who was taken to the emergency room with complaints of increasing abdominal pain, rectal bleeding, weight loss, and dyspnea for the last three months. Endoscopic examination revealed polypoid lesions in the duodenum and the descending colon. We diagnosed neuroendocrine small-cell lung cancer based on histopathological and immunohistochemical staining.Management and outcome: A cisplatin (d1, 60 mg/m2/day)-etoposide (d1 to d3, 120 mg/m2/day) regimen was given every three weeks as palliative chemotherapy. After the three course of chemotherapy, the lung radiograph showed a decline in hilar expansion and there was no pleural effusion. Then, he died of acute respiratory failure two weeks after radiotherapy of brain. DISCUSSION: Gastrointestinal tract metastasis of lung cancer is recognized synchronously with or rarely before diagnosis. It is generally recognized after the diagnosis of lung cancer. These patients often have other concurrent body metastases. Prognosis is poor, and survival expectation is short. The most common metastases to the gastrointestinal tract are squamous and large cell lung cancer metastases. Our aim is to emphasize the importance of immunohistochemical examination for masses in the gastrointestinal tract and to present this rare case of synchronous duodenal and colonic metastases of small-cell lung cancer.

RESUMO

INTRODUCTION: Tyrosine kinase inhibitors and immune checkpoint inhibitors are widely used in advanced renal cell carcinoma. Here we reported a left ventricular dysfunction associated with axitinib and nivolumab experience in this patient with heart failure. CASE REPORT: A 70-year-old male patient with advanced renal cell carcinoma was treated with interferon alpha-2b 10 million U thrice weekly. After progression, sunitinib provided 18 months of stable disease. In third line, the patient was treated with axitinib 10 mg daily. Under axitinib, the patient presented with dyspnea and palpitations. The diagnostic work-up showed a left ventricular dysfunction with an ejection fraction (EF) of 35% in echocardiography. He was treated with diuretics, acetylsalicylic acid 100 mg and low molecular weight heparin.Management and outcome: After excluding cardiac ischemic and pulmonary pathologies, we concluded a possible adverse event diagnosis of axitinib-related cardiotoxicity. After close follow up for cardiac dysfunction, the patient was treated with nivolumab 3 mg/kg every two weeks. The initial EF was 32%. After three months therapy, the patient was asymptomatic for cardiac dysfunction and EF was 50%. CT scan showed partial response in pulmonary lesions. DISCUSSION: We have limited no data about cardiotoxicity associated axitinib and limited data about ICIPs. Our case is unique by providing data about how to manage a metastatic RCC patient with left ventricular dysfunction under axitinib and how to follow-up the cardiac functions while under nivolumab therapy.

RESUMO

Opsoclonus-myoclonus syndrome is a rare disease and traditionally described as "dancing eyes, dancing feet syndrome." It is characterized by opsoclonus (oscillations of the eyes in either horizontally or vertically) and myoclonus (spontaneous jerky movements of the limbs and trunk). There are numerous etiological factors defined such as paraneoplastic, para-infectious, toxic-metabolic, and idiopathic causes. The experience of opsoclonus-myoclonus syndrome in adults is very limited. Here, we present a case of treatment-refractory paraneoplastic opsoclonus-myoclonus syndrome associated with small-cell carcinoma of the lung.

RESUMO

INTRODUCTION: Mucinous adenocarcinomas of the testicular surface epithelial tumors are very rare and are similar to malignant ovarian-type surface epithelial tumors. Although only 32 cases have been reported to date, there are only five cases of primary testicular mucinous carcinoma with access to literature in English. So there is still limited information about clinical, etiopathogenesis and treatment options. CASE REPORT: In this article, we discuss a 56-year-old male patient diagnosed with testicular mucinous adenocarcinoma due to its rarity in the light of literature review.Management and outcome: We preferred cisplatin-paclitaxel regimen for adjuvant treatment. We then used sequential treatments including oxaliplatin, 5-fluorourasil, etoposide, gemcitabine, and docetaxel to treat metastatic disease. The patient underwent lung metastasectomy for the first relapse. The patient was diagnosed in November 2013 and the response to treatment was evaluated in December 2019 and stable disease was detected. The patient, who has a total survival of 73 months, is still under treatment. DISCUSSION: Excluding malign transformation and borderline mucinous testicular tumors from mucinous cystadenomas of the testis, the knowledge on carcinogenesis, clinical course, and treatment of primary testicular mucinous adenocarcinomas is very limited.

RESUMO

INTRODUCTION: Oral cavity malignancies constitute 30% of head and neck cancers. The most common distant metastatic sites of glottic carcinoma are usually lung, liver and bone. Although the cutaneous metastasis of head and cancers have been reported with an incidence of 0.7-2.4%, skin metastasis of glottic carcinoma is extremely rare. CASE REPORT: A 69-year-old male patient was admitted to the emergency department with hemoptysis, dyspnea, weakness in lower extremities and difficulty in swallowing. There were subcutaneous lesions with a diameter of 2-5 cm in the scalp, posterior chest wall, nose and abdomen. In addition, there was an ulcerating, painful mass on the right lateral part of the tongue. The biopsy of lesions on tongue and skin revealed a glottic squamous cell carcinoma with cutaneous metastasis.Management and outcome: The patient was treated with cisplatin 50 mg/m2 on day 1, cetuximab 500 mg/m2 on day 1 and 5-fluorouracil 1000 mg/m2 daily on days 1 and 2, repeated every two weeks. After the first cycle of chemotherapy, the lesions on the skin regressed and dysphagia improved. DISCUSSION: There are limited data about the incidence, diagnostic measures and treatment modalities of glottic cancer with cutaneous metastasis. Our case could provide an important experience to literature by its atypical presentation and treatment-sensitive nature.

RESUMO

Cancer is one of the most common causes of death all over the World (Rahib et al. in Cancer Res 74(11):2913-2921, 2014; Silbermann et al. in Ann Oncol 23(Suppl 3):iii15-iii28, 2012). It is crucial to diagnose this disease early by effective screening methods and also it is very important to acknowledge the community on various aspects of this disease such as the treatment methods and palliative care. Not only the oncologists but every medical doctor should be educated well in dealing with cancer patients. Previous studies suggested various opinions on the level of oncology education in medical schools (Pavlidis et al. in Ann Oncol 16(5):840-841, 2005). In this study, the perspectives of medical students on cancer, its treatment, palliative care, and the oncologists were analyzed in relation to their educational status. A multicenter survey analysis was performed on a total of 4224 medical school students that accepted to enter this study in Turkey. After the questions about the demographical characteristics of the students, their perspectives on the definition, diagnosis, screening, and treatment methods of cancer and their way of understanding metastatic disease as well as palliative care were analyzed. The questionnaire includes questions with answers and a scoring system of Likert type 5 (absolutely disagree = 1, completely agree = 5). In the last part of the questionnaire, there were some words to detect what the words "cancer" and "oncologist" meant for the students. The participant students were analyzed in two study groups; "group 1" (n = 1.255) were phases I and II students that had never attended an oncology lesson, and "group 2" (n = 2.969) were phases III to VI students that had attended oncology lessons in the medical school. SPSS v17 was used for the database and statistical analyses. A value of p < 0.05 was noted as statistically significant. Group 1 defined cancer as a contagious disease (p = 0.00025), they believed that early diagnosis was never possible (p = 0.042), all people with a diagnosis of cancer would certainly die (p = 0.044), and chemotherapy was not successful in a metastatic disease (p = 0.003) as compared to group 2. The rate of the students that believed gastric cancer screening was a part of the national screening policy was significantly more in group 1 than in group 2 (p = 0.00014). Group 2 had a higher anxiety level for themselves or their family members to become a cancer patient. Most of the students in both groups defined medical oncologists as warriors (57% in group 1 and 40% in group 2; p = 0.097), and cancer was reminding them of "death" (54% in group 1 and 48% in group 2; p = 0.102). This study suggested that oncology education was useful for the students' understanding of cancer and related issues; however, the level of oncology education should be improved in medical schools in Turkey. This would be helpful for medical doctors to cope with many aspects of cancer as a major health care problem in this country.

RESUMO

INTRODUCTION: The mechanism of oxaliplatin (OXA) induced pulmonary toxicity is not fully understood. AIM OF THE STUDY: The present study was designed to investigate the pulmonary toxicity of OXA that has been reported in previous studies. Study design: animal experiments. MATERIAL AND METHODS: A total of 40 female Wistar rats were divided into 5 groups. In group 1, 5% glucose was injected intra-peritoneally; then the rats were sacrificed on day 14. OXA was administered in groups 2, 3, 4, and 5; then the animals were sacrificed on day 7 in group 2, day 14 in group 3, day 28 in group 4 and day 48 in group 5. The groups were further categorized as short-term administration and long-term administration groups. Furthermore, tissue glutathione peroxidase (GPX) activity was measured in all rats. RESULTS: The mean GPX activities were 0.66 U/mg in the sham group, 0.74 U/mg in the short-term groups, and 0.74 U/mg in the long-term groups. We found that long-term OXA administration causes pulmonary toxicity resulting in increased intra-alveolar/interstitial macrophages and interstitial pneumonia. Similarly, we found reduced and permanent tissue GPX activity in rats that received OXA in higher doses and for a long term. CONCLUSIONS: Long-term OXA therapy causes toxic changes in the lung tissue.

RESUMO

BACKGROUND: There are insufficient predictive markers for renal cell carcinoma (RCC). METHODS: A total of 308 metastatic RCC patients were analyzed retrospectively. RESULTS: The increased hemoglobin (Hb) group had significantly higher progression-free survival and overall survival (OS) compared with the decreased Hb group at 11.5 versus 6.35 months (p < .001) and 21.0 versus 11.36 months (p < .001) respectively. The 1- and 3-year OS rates were higher in the Hb increased group, i.e., 84% versus 64% and 52% versus 35% respectively. CONCLUSIONS: The present study showed that increased Hb levels after tyrosine kinase inhibitor therapy could be a predictive marker of RCC.

RESUMO

The objectives of this study were to compare progression-free survival (PFS) with somatostatin analog (SSA) versus chemotherapy (CTx) in first-line therapy and to determine the patient group in which these treatments were more effective in neuroendocrine tumors (NETs) with a Ki-67 index of 20% or less. Patients who received SSA or CTx and had unresectable locally advanced and metastatic NETs with a Ki-67 index of 20% or less were retrospectively selected from 13 centers in the Turkish database between 2000 and 2015. One hundred and sixty-five patients were enrolled. The median age was 56 years and the male-to-female ratio was 1.09. Seventy-four (45%) patients were of grade 1 NET and 91 (55%) were of grade 2. SSA was given to 104 patients, whereas 61 were treated with CTx. The objective response rate after SSA was 15.4%; another 73.1% had stable disease. The objective response rate after CTx was 36.1%, and 40.9% had stable disease (P=0.008). The median PFS in SSA patients was 21 months (95% confidence interval: 12.4-29.6), and 8 months for CTx (95% confidence interval: 5.5-10.6) (P<0.001). There was no significant difference between PFS of receiving SSA and CTx in pancreatic neuroendocrine tumor (PNET) patients; however, the PFS of receiving SSA was longer in non-PNET patients (P<0.001). SSA was better treatment in advanced NET patients with a Ki-67 index of less than 5%, having a primary resected and a performance status of 0 (P<0.05). SSA may be preferred over CTx in advanced NET patients with low-to-intermediate grade.

RESUMO

PURPOSE: Each year, 12.7 million people learn that they have cancer and 8.2 million people die of cancer worldwide. Cancer is a major public health issue which causes fundamental changes in the lives of patients and their families. The purpose of this study was to evaluate the lives of patients after diagnosis and determine the changes in their lifestyles. METHODS: Between September 2013 to December 2013, a questionnaire consisting of 22 questions was administered during a face to face interview to patients at 13 different Oncology Units in Turkey. Each patient was queried during the administration of his/her chemotherapy. Eight of the questions featured independent choices, and 14 had dependent (multiple) choices. RESULTS: A total of 1300 patients were included in the study. Of patients 9.5% were 71 years of age and older which was the oldest age group. The mean patient age was 54.6±13.8 years. Of the whole group of patients 58.5% were female and 41.5% male. After diagnosis, 64% of the patients reported that they were complying with guidelines for a healthy lifestyle and 80% said that they were eating healthier food. At the time they filled in the questionnaire, more than half of the patients (57.3%) felt optimistic about their disease. CONCLUSIONS: Diagnosis of cancer may change the patients' dietary and reading habits, social relationships, activities and more importantly, their point of life view.

RESUMO

PURPOSE: Persistent postmastectomy pain syndrome (PMPS) is one of the most important disturbing symptoms. Posttraumatic stress disorder (PTSD) is an anxiety disorder which is characterized by reactions to reminders of the trauma that has been experienced. The purpose of this study is to evaluate the predictors of PMPS and PTSD in Turkish breast cancer survivors and the correlation between PMPS and PTSD. METHOD: The study is designed as a multicenter survey study. Breast cancer patients in remission were evaluated. Patients were evaluated with structured questionnaires to assess the PMPS and clinical parameters associated with it. The Turkish version of the posttraumatic stress disorder checklist-civilian version (PCL-C) was used. RESULTS: Between February 2015 and October 2015, 614 breast cancer survivors in outpatient clinics were evaluated. The incidence of PMPS documented is 45.1 %. In the multivariate analysis low income, presence of PTSD and <46 months after surgery were associated with increased risk of PMPS. PTSD was documented in 75 %, and the mean PCL-C score was 32.4 ± 11.1. PMPS and being married at the time of the evaluation were linked with PTSD. CONCLUSIONS: It is the first data about the association between PMPS and PTSD. The clinicians should be aware of PMPS and PTSD in breast cancer survivors.

RESUMO

Gastric carcinoma is the first cause of death worldwide. In previous studies that included best supportive care and chemotherapy comparison, chemotherapy survival time was four to five months more than best supportive care. This time was reported as seven to nine months in cisplatin and fluorouracil therapy. We aimed to call attention to non-progression survival time which was being longer with cisplatin and fluorouracil therapy in three metastatic gastric carcinoma patients who were on hemodialysis due to chronic renal impairment related to diabetic nephropathy. We determined that this regimen was well tolerated with hemodialysis, and the median time to progression was eight months (range 7-10). This time was similar to the time results of previous studies. In our hypothesis, hemodialysis may increase the time to progression significantly and we aimed to discuss the hypothetical relation between dialysis membrane and circulating tumor cells.
