RESUMEN

Breast cancer (BC) is the most common cancer among women and a major cause of death. Signal Peptide-Cub-Epidermal growth factor domain-containing protein-1 (SCUBE1) is secreted under hypoxia and inflammatory conditions from platelet alpha granules. Its biological function is uncertain, although it may be a procoagulant substance in cancer patients. SCUBE1 is useful for identifying thrombotic diseases, including cancers and acute coronary syndromes. D-dimer reflects the relationship between coagulation activation and fibrinolysis; namely, thrombosis and D-dimer levels are closely linked. This is the first investigation of the potential diagnostic and prognostic value of SCUBE1 levels in patients with BC. Fifty patients and 33 age-matched and body mass index-matched healthy controls were enrolled. Blood samples were collected before chemotherapy regimens commenced. Serum SCUBE1 and D-dimer levels were measured before adjuvant chemotherapy and were compared to the healthy controls. SCUBE1 levels were determined using an enzyme-linked immunosorbent assay (ELISA) method. SCUBE1 and D-dimer levels were significantly higher in patients than in the controls (p = 0.03 and p < 0.001, respectively). A cut-off value of 1.55 ng/mL for SCUBE1 was associated with 62% sensitivity and 72.7% specificity and with positive predictive value of 77.5% and negative predictive value of 55.8%. Two patients with high SCUBE1 and D-dimer levels also developed pulmonary embolism. SCUBE1 may indicate hypercoagulability in patients with BC and thus help identify patients at greater risk of thrombosis and requiring anti-thrombosis treatment. SCUBE1 may also be used as an assistant test for identifying patients at risk of BC.

RESUMEN

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.

RESUMEN

BACKGROUND: Increased early diagnosis and improved treatment options have decreased the mortality rate of breast cancer and increased the survival rate. Healthy lifestyle behaviors are very important in breast cancer survivors as they reduce mortality and morbidity rates, cancer recurrence frequency, and side effects of treatment and improve health. This study was conducted to evaluate the effectiveness of a health promotion training intervention in breast cancer survival. MATERIALS AND METHODS: The study is a quasi-experimental, pre-test-post-test and single-group study. It was conducted with 43 women breast cancer survivors. The "Healthy Lifestyle Behaviors Scale II" was used to collect the data. Four sessions of training were given to the women once a week, and a 3-month post-training follow-up was performed. The t-test, Wilcoxon analysis, and Spearmen correlation analysis were used to evaluate the data. RESULTS: Pre-training and post-training scores in the sub-dimensions and total scores of the healthy lifestyle behavior scale showed that the training was highly effective. There was a significant increase in all sub-dimensions and total scale post-training scores (P < 0.05). In the correlation analysis, a negative correlation was found between age and physical activity, between elapsed time after diagnosis and nutrition, and between elapsed time after diagnosis and spiritual development (P < 0,05). However, there was a positive correlation between educational status and nutrition (P < 0.05). CONCLUSIONS: The results show that a health promotion training program covering physical activity/exercise, healthy nutrition, effective communication, coping with stress, and increasing health responsibility had positive effects on healthy lifestyle behaviors in this population, and age, educational status, and elapsed time after diagnosis influence healthy lifestyle behaviors in survival.

RESUMEN

OBJECTIVE: Surgical resection of asymptomatic primary colorectal cancer in patients presenting with synchronous unresectable metastatic disease is controversial. Concerns and controversies remain over combining cytotoxic chemotherapy with bevacizumab in this patient population. METHODS: We identified medical records of 99 patients with synchronous metastatic primary colorectal cancer who received chemotherapy with bevacizumab as their initial treatment. The incidence of subsequent use of surgery and surgical outcomes were recorded. Patients were also assessed for overall survival. RESULTS: Patients who received bevacizumab-containing chemotherapy for synchronous metastatic primary colorectal cancer were divided into the non-surgery and surgery groups according to the resection status of their asymptomatic primary tumor. In the non-surgery group, two patients (4.4%) underwent additional surgery, while three patients (5.7%) required surgery for rectovesical fistula in the surgery group. The median overall survival was 17 months for the non-surgery group (95% CI: 10.6-23.3 months) and 23 months for the surgery group (95% CI: 21.3-24.6 months; P = 0.322). CONCLUSIONS: This study utilizing chemotherapy with bevacizumab did not result in an increased rate of morbidity related to the unresected primary tumor. Survival is not compromised by leaving the primary colon tumor intact.

RESUMEN

The objective of the study was to evaluate the impact of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) imaging on nodal staging for head and neck cancers. This was a retrospectively analyzed single institution study. The study population consisted of 36 patients with head and neck cancers who were evaluated with PET/CT and went on to neck dissection. All of them had clinically and radiographically negative neck (N0) and each patient underwent PET/CT imaging before undergoing selective neck dissection for N0 disease. Tissues were submitted for histopathologic examination and were oriented for the pathologist to permit correlation between the histopathologic findings and the imaging results. The sizes of the lymph nodes and the maximum standardized uptake values (SUVmax) measured from PET/CT images were compared with the histopathologic findings. All primary tumors were visualized with PET/CT. On histopathological examination, 19 patients had positive and 17 patients had negative lymph nodes. Receiver operating characteristic analyses were used to predict the optimal corrected SUVmax cutoffs; the optimal value was 2.95 for respective outcomes of lymph node involvement. This cutoff value yielded 84.2% sensitivity and 76.5% specificity for nodal-level staging. PET/CT proved to be accurate in 27 (75%) patients and inaccurate in 9 (25%) patients. PET/CT was a valuable tool to assess nodal stage of head and neck cancers, and should be considered before surgical treatment.

RESUMEN

BACKGROUND: Clinical care of patients with cancer mostly focuses on medical management with less attention on disease-related malnutrition. The Global Leadership Initiative on Malnutrition (GLIM) released new criteria for diagnosing malnutrition, but the validation of these criteria in treatment-naïve patients with cancer is not well documented. This study aimed to investigate the application of the GLIM criteria in nutrition assessment and mortality prediction in treatment-naïve patients with cancer. METHODS: A total of 267 patients newly diagnosed with different types of cancer were enrolled. Nutrition status was assessed with the Patient-Generated Subjective Global Assessment (PG-SGA) at outpatient clinic admission during the data collection period. Furthermore, after the GLIM criteria publication, nutrition status was assessed retrospectively using the GLIM criteria in the same cohort to assess validity. The agreement between the tools was calculated using kappa statistics, and the association of malnutrition according to each tool and mortality was analyzed using logistic regression analysis. RESULTS: The mean age of the patients was 58.06 ± 12.6 years, and 42.7% were women. The prevalence of malnutrition was 60.3% with GLIM criteria and 53.6% with PG-SGA. Agreement between tools was moderate (κ = 0.483, P < 0.001). During a median follow-up period of 23.6 months, 99 deaths occurred. Both GLIM-defined and PG-SGA-defined malnutrition was independently associated with 2-year mortality after adjusting for age, sex, presence of comorbidities, and stage of cancer. CONCLUSIONS: Our findings support the validation of GLIM in diagnosing malnutrition and predicting 2-year mortality among treatment-naïve patients with cancer.

RESUMEN

Mucinous breast carcinoma (MBC) is a rare histological type of breast cancer and rarely associated with advanced disease. We report a case that had MBC with an isolated adrenal metastasis which was removed by laparoscopic adrenelectomy. This case is unique due to the unexpected metastasis of pure mucinous carcinoma developed after 4 years of hormone therapy.

RESUMEN

PURPOSE: To evaluate the effect of adding adjuvant ifosfamide/doxorubicin combination chemotherapy (CTX) to adjuvant radiotherapy (RT) on the survival in patients with surgically treated high-risk soft tissue sarcomas (STSs). METHODS: The study included 69 patients (group A) receiving adjuvant RT and 74 patients (group B) receiving adjuvant CTX after adjuvant RT. RESULTS: The median relapse-free survival (RFS) was 18.2 months (95% CI, 11.9-43.4) in group A and 27.2 months (95% CI, 17.6-36.8) in group B (p = 0.004). The median overall survival (OS) was 45.6 months (95% CI, 26.4-64.8) in group A and 110.1 mo (95% CI, 44.3-175.8) in group B (p = 0.007). Receiving adjuvant CTX was an independent predictive factor for both RFS [HR: 0.482, (0.307-0.757), p = 0.002) and OS (HR: 0.549, [0.348-0.867], p = 0.010). CONCLUSION: There are conflicting literature data regarding the survival benefit of adjuvant CTX for surgically treated STSs. However, appropriate patient selection may provide a significant survival benefit in RFS and OS with CTX in the adjuvant treatment of high-risk STSs.

RESUMEN

PURPOSE: To investigate the importance of mucinous histopathology on the assessment of tumor response in patients with metastatic colorectal cancer (mCRC) receiving regorafenib. MATERIALS AND METHOD: All patients diagnosed with histologically confirmed mCRC in 2 oncology centers between 2013 and 2018 were retrospectively analyzed. Among 678 patients diagnosed with mCRC, 103 patients were treated with regorafenib. Ninety-four of these patients who had used at least 2 cycles of regorafenib and evaluable for treatment response were included in the analysis. Histopathologically, 18 patients with mucinous adenocarcinoma and 76 patients with nonmucinous adenocarcinoma were compared in terms of response rate and survival durations. RESULTS: Median follow-up duration of 6 months, median age of the patients was 61 (34-77) years. While 19.1% of the patients had mucinous histology, 80.9% had nonmucinous histology. The overall response rate was significantly lower in the mucinous subgroup than the nonmucinous subgroup (5.6% vs 43.4%, respectively, P = 0.003). Similarly, both progression-free survival (3.0 vs 4.0 months, respectively, P = 0.011) and overall survival duration were shorter in the mucinous subgroup (3.0 vs 7.0 months, P = 0.016, respectively) compared with the nonmucinous subgroup. CONCLUSION: The histological subgroup may predict tumor response in mCRC patients receiving regorafenib. Its efficacy on nonmucinous histology had significantly more favorable than mucinous subtype.

RESUMEN

BACKGROUND: Merkel cell carcinoma (MCC) is a rare but highly aggressive neuroendocrine carcinoma of the skin. In this study, we aimed to evaluate the clinicopathologic characteristics, treatment outcomes, and survival of MCC cases in Turkey. MATERIALS AND METHODS: The patients diagnosed with MCC between 1999 and 2018 at twenty different centers in Turkey were included in the study. Patient and tumor characteristics and adjuvant and metastatis treatment outcomes were analyzed retrospectively. RESULTS: The median age of totally 89 patients was 70 (26-93). The most common primary location was lower limbs (n = 29, 32.5%). Immunohistochemically, CK20 positivity was present in 59 patients (66.3%). Only two patients had secondary malignancy. The majority of the patients (n = 76, 85.4%) were diagnosed at the localized stage. Surgery was performed for all patients in the early stage, and adjuvant radiotherapy or/and chemotherapy was applied to 52.6% (n = 40) of nonmetastatic patients. The median follow-up was 29 months. Recurrence developed in 21 (27.6%) of the 76 patients who presented with local or regional disease. Two-year disease-free survival (DFS) was 68.1% and 5-year DFS was 62.0% for localized stage. The 5-year DFS was similar for patients receiving adjuvant treatment (chemotherapy, radiotherapy, or sequential chemoradiotherapy) and without adjuvant therapy (P > 0.05). Two-year overall survival in patients who presented with localized disease was 71.3% and 18.5% in metastatic patients (P < 0.001). In the metastatic stage, platinum/etoposide combination was the most preferred combination regimen. Median progression-free survival (PFS) in first-line chemotherapy was 7 months (95% confidence interval: 3.5-10.5 months; standart error: 1.78). CONCLUSIONS: Although MCC is rare in Turkey, the incidence is increasing. Gender, CK20 status, tumor size, lymph node involvement, and adjuvant treatment were not associated with recurrence.

RESUMEN

Familial Mediterranean fever (FMF) is a genetic multisystem disorder of unknown etiology characterized by recurrent episodes of fever and pain due to acute inflammation of the peritoneum, synovia, or pleura. Up to 25% of patients with FMF report muscle pain. Myalgia may be a spontaneous pattern, exercise-induced pattern, or protracted febrile myalgia syndrome (PFMS). PFMS is characterized by severe paralyzing myalgia, high fever, abdominal pain, diarrhea, arthritis/arthralgia, and transient vasculitic rashes mimicking Henoch-Schonlein purpura. The episodes last for 4-6 weeks, except in those patients treated with corticosteroids. The PFMS may recur even under colchicine prophylaxis. We describe a 30-year-old pregnant Turkish woman with known FMF and under colchicine prophylaxis, with severe myalgia for 8 weeks, emphasizing the importance of a different clinical pattern of PFMS even in the absence of other symptoms.

RESUMEN

PURPOSE: Germ cell tumors (GCTs) are rare and highly curable malignancies. However, salvage treatments for relapsed or refractory disease are needed in approximately 20-60% of the patients. As salvage therapy, autologous stem cell transplantation (ASCT) administered after high-dose chemotherapy (HDCT) may be a feasible option as well as standard dose chemotherapy (SDCT). This study aimed to evaluate the efficacy and toxicity of ASCT in salvage therapy of GCTs retrospectively.  Materials and Methods: Male patients older than 18 years of age who underwent ASCT due to a relapsed/refractory GCT were included in the study. RESULTS: The median age of 18 patients included in the study was 28 (19-46). The majority of patients (n:16, 88.8%) had non-seminomatous GCT histology. All of the patients had relapsed or refractory GCTs and received bleomycin, etoposide, cisplatin (BEP) combination therapy previously. Half of the patients were in the poor risk group. ASCT was administered as a second-line therapy in 14 (77.7%) patients and third-line therapy in four (22.2%) patients. There is no ASCT-related exitus. Febrile neutropenia (FN) developed in almost all patients. Complete response (CR) was obtained in 7 (38.8%) patients, partial response (PR) in four (22.2%) patients after ASCT. The 2-year PFS was 44.4% and the median PFS was 8.7 (2.7-12.6) months. Median OS was 22.7 (3.9-41.7) months and 3 years OS was 50.0%. CONCLUSION: In conclusion, ASCT was found to be an effective and safe treatment option in salvage therapy of GCT patients in our study.

RESUMEN

PURPOSE: Right-sided colon cancers (RCCs) and left-sided colon cancers (LCCs) have different embryological, epidemiological, physiological, pathological, genetic, and clinical characteristics, which result in differences in the course, prognosis, and outcome of disease. This study aimed to compare RCCs and LCCs regarding clinicopathological and survival characteristics. METHODS: The present retrospective study included data of patients who were followed-up and treated for colon cancer from 2008 through 2017. Rectosigmoid, descending colon, and splenic flexure tumors were considered LCC, whereas hepatic flexure and ascending colon tumors were considered RCC. Tumors were staged according to the American Joint Committee on Cancer classification. RESULTS: The study included 1725 patients (female, 58.7%) having colon cancer with a mean age of 64±12 years. Of the patients, 83.2% (n=1436) had LCC and 16.8% (n=289) had RCC. The rate of patients aged ≥65 years and the rate of patients with a family history of colon cancer were higher in the RCC patients. The rate of metastatic patients was 29.1% in the RCC group and 23.2% in the LCC group (p=0.087). The median follow-up period was 18 months in the RCC group and 23 months in the LCC group (p=0.011). Although the median survival time was higher in the LCC group (62 vs. 43 months), no significant difference was determined between the RCC and LCC groups in terms of survival. CONCLUSIONS: There are numerous clinicopathological differences between RCC and LCC and these differences are reflected in prognostic and survival differences among certain subgroups.

RESUMEN

In this retrospective study, the investigators examined blood cultures from patients that had been diagnosed with bacteremias over a 3-y period. The study was conduced at Kocatepe University Hospital (Middle Anatolia, Turkey). Blood samples that arrived at the university's microbiology laboratory between 2002 and 2005 were evaluated retrospectively. These samples were classified as contamination, false positivity, community-acquired bacteremia (CAB), or hospital-acquired bacteremia (HAB). Patient age and sex, foci of bacteremia, present comorbidities, predisposing factors, pathogens, and mortality rates were evaluated. A total of 1783 blood cultures that had been drawn from 1441 patients during this 3-y period were examined retrospectively. Of 354 positive isolates, 61 (17.2%) were CABs and 293 (82.8%) were HABs. In HABs, the most commonly isolated microorganisms were Staphylococcus aureus (37.5%), coagulase-negative staphylococci (29.7%), and Escherichia coli (10.2%); in CABs, the most commonly isolated microorganisms were S aureus (29.5%), Brucella spp (26.2%), and E coli (24.6%). Crude mortality rates were determined to be 15.2% for HABs and 12.7% for CABs. This study yielded data on the most common foci of bacteremia, microbiologic factors, and the epidemiology associated with HABs and CABs. It is hoped that these data will enhance empirical antibiotic therapeutic approaches, thereby preventing delays in treatment and decreasing mortality rates associated with bacteremias.

RESUMEN

BACKGROUND: We investigated the role of standardized uptake values (SUVs) of the primary tumor in small cell lung cancer (SCLC) patients. PATIENTS AND METHODS: The relationship between SUV and response to treatment was investigated using receiver operating characteristic (ROC) curve analysis, and the efficient cut-off value for detecting response to treatment was determined. The effects of SUV on response to treatment and survival were investigated. RESULTS: 90 patients with a median age of 58 years (range 39-83 years) were included. Median follow-up was 11 months. The suitable cut-off SUV for determination of response was found to be 10 in ROC analysis. The sensitivity and specificity of this value were 85.7% (95% confidence interval (95% CI) 63-96) and 61.8% (95% CI 49-73) (area under the curve 0.783; p = 0.0001), respectively. The overall objective response rate in patients with involvement above the cut-off value was 93.3% compared to 59.1% in those with involvement below the cut-off value (p < 0.0001). In uni- and multivariate analysis, favorable effects of limited-stage disease on response to treatment were established (p < 0.05). The effect of an SUV higher than the cut-off value on progression-free survival was borderline (p = 0.085). CONCLUSION: These data may contribute to identifying prognostic disease characteristics and response to treatment.

RESUMEN

In the head and neck mucosa, neuroendocrine carcinomas of the oral cavity is rare. Herein, we present the first report of a small cell neuroendocrine carcinoma in a 54-year-old man on the right lateral posterior tongue. It is important to remember that although neuroendocrine small cell carcinomas (SCCs) are most commonly seen in the lung, they rarely may arise in the extrapulmonary sites, including salivary glands, as well. As there is not any standard therapeutic regimen already existing, it is important to be aware of and to know how to deal with such rare cases.

RESUMEN

Wernicke's encephalopathy (WE) is a disease classically associated with nutrition deficiency. It is characterized by typical symptoms like confusion, ataxia and ophthalmoparesis, and developes due to thiamine deficieny in alcoholic patients. Recently, it has been shown that WE could ocur in patients with gastric carcinoma without a history of alcohol use. In this paper, we have made some suggestions about early diagnosis, treatment and prevention of WE by discussing the development of WE in a patient with unresectable gastric carcinoma, who had been inpatient for a long time and given radiotherapy and chemotherapy.

RESUMEN

Rupture of the silicon port catheter is a relatively rare complication. Ruptured part usually embolizes; therefore, removal of foreign body may be difficult. These ports usually migrate to right-sided chambers, main pulmonary arteries, and pulmonary subbranches. Different devices such as snares, basket catheters, and ablation catheters are utilized for retrieval. Hereby, we report successful extraction of an embolized 10-cm tip of a vascular access port using a macro snare catheter.

RESUMEN

BACKGROUND: Non-epithelial malignant ovarian tumors and clear cell carcinomas, Brenner tumors, transitional cell tumors, and carcinoid tumors of the ovary are rare ovarian tumors (ROTs). In this study, our aim was to determine the clinicopathological features of ROT patients and prognostic factors associated with survival. MATERIALS AND METHODS: A total of 167 patients with ROT who underwent initial surgery were retrospectively analyzed. Prognostic factors that may influence the survival of patients were evaluated by univariate and multivariate analyses. RESULTS: Of 167 patients, 75 (44.9%) were diagnosed with germ-cell tumors (GCT) and 68 (40.7%) with sex cord-stromal tumors (SCST); the remaining 24 had other rare ovarian histologies. Significant differences were found between ROT groups with respect to age at diagnosis, tumor localization, initial surgery type, tumor size, tumor grade, and FIGO stage. Three-year progression-free survival (PFS) rates and median PFS intervals for patients with other ROT were worse than those of patients with GCT and SCST (41.8% vs 79.6% vs 77.1% and 30.2 vs 72 vs 150 months, respectively; p=0.01). Moreover, the 3-year overall survival (OS) rates and median OS times for patients with both GCT and SCST were better as compared to patients with other ROT, but these differences were not statistically significant (87.7% vs 88.8% vs 73.9% and 170 vs 122 vs 91 months, respectively; p=0.20). In the univariate analysis, tumor localization (p<0.001), FIGO stage (p<0.001), and tumor grade (p=0.04) were significant prognostic factors for PFS. For OS, the univariate analysis indicated that tumor localization (p=0.01), FIGO stage (p=0.001), and recurrence (p<0.001) were important prognostic indicators. Multivariate analysis showed that FIGO stage for PFS (p=0.001, HR: 0.11) and the presence of recurrence (p=0.02, HR: 0.54) for OS were independent prognostic factors. CONCLUSIONS: ROTs should be evaluated separately from epithelial ovarian cancers because of their different biological features and natural history. Due to the rarity of these tumors, determination of relevant prognostic factors as a group may help as a guide for more appropriate adjuvant or recurrent therapies for ROTs.

RESUMEN

INTRODUCTION: We investigated the impact of modern chemotherapy regimens and bevacizumab following pulmonary metastasectomy (PM) from metastatic colorectal cancer (CRC). METHODS: A total of 122 consecutive patients who were curatively resected for pulmonary metastases of CRC in twelve oncology centers were retrospectively analysed between January 2000 and April 2012. RESULTS: Of 122 patients, 14 did not receive any treatment following PM. The remaining 108 patients received fluoropyrimidine-based (n = 12), irinotecan-based (n = 56) and oxaliplatin-based (n = 40) chemotherapy combinations. Among these, 52 patients received bevacizumab (BEV) while 56 did not (NoBEV). Median recurrence-free survival (RFS) was 17 months and median overall survival (OS) has not been reached at a median follow-up of 25 months after PM. Three and five-year OS rates were 66% and 53%, respectively. RFS and OS were similar, irrespective of the chemotherapy regimen or BEV use. Positive pulmonary margin, KRAS mutation status, and previous liver metastasectomy were negative independent prognostic factors for RFS, while pathologically confirmed thoracic lymph node involvement was the only negative independent prognostic for OS in multivariate analysis. CONCLUSIONS: No significant RFS or OS difference was observed in respect to chemotherapy regimens with or without BEV in patients with pulmonary metastases of CRC following curative resection.
