RESUMEN
To evaluate radiological and clinical features in metastatic anaplastic lymphoma kinase+ non-small cell lung cancer patients and crizotinib efficacy in different lines. This national, non-interventional, multicenter, retrospective archive screening study evaluated demographic, clinical, and radiological imaging features, and treatment approaches in patients treated between 2013-2017. Totally 367 patients (54.8% males, median age at diagnosis 54 years) were included. Of them, 45.4% were smokers, and 8.7% had a family history of lung cancer. On radiological findings, 55.9% of the tumors were located peripherally, 7.7% of the patients had cavitary lesions, and 42.9% presented with pleural effusion. Pleural effusion was higher in nonsmokers than in smokers (37.3% vs. 25.3%, Pâ =â .018). About 47.4% of cases developed distant metastases during treatment, most frequently to the brain (26.2%). Chemotherapy was the first line treatment in 55.0%. Objective response rate was 61.9% (complete response: 7.6%; partial response: 54.2%). The highest complete and partial response rates were observed in patients who received crizotinib as the 2nd line treatment. The median progression-free survival was 14 months (standard error: 1.4, 95% confidence interval: 11.2-16.8 months). Crizotinib treatment lines yielded similar progression-free survival (Pâ =â .078). The most frequent treatment-related adverse event was fatigue (14.7%). Adrenal gland metastasis was significantly higher in males and smokers, and pleural involvement and effusion were significantly higher in nonsmokers-a novel finding that has not been reported previously. The radiological and histological characteristics were consistent with the literature data, but several differences in clinical characteristics might be related to population characteristics.

AIM: Description of patient characteristics, effectiveness and safety in Turkish patients treated with pazopanib for metastatic soft tissue sarcoma (STS). PATIENTS AND METHODS: This multicenter study is based on retrospective review of hospital medical records of patients (≥ 18 years) treated with pazopanib for non-adipocytic metastatic STS at 37 Oncology clinics across Turkey. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS) and overall survival (OS) were evaluated with further analysis of data on the three most common histological subtypes (leiomyosarcoma [LMS], undifferentiated pleomorphic sarcoma [UPS], synovial sarcoma [SS]) in the cohort. RESULTS: Data of 552 adults (57.6% women, median age: 52 years) were analyzed. DCR and ORR were 43.1% and 30.8%, respectively. Median PFS was 6.7 months and OS was 13.8 months. For LMS, UPS and SS, median PFSs were 6.1, 5.9 and 7.53 months and median OSs were 15.03, 12.87 and 12.27 months, respectively. ECOG ≥ 2 was associated with poor PFS and OS. Liver metastasis was only a factor for progression. Second-line use of pazopanib (vs. front-line) was associated with better PFS, its use beyond third line predicted worse OS. Adverse events (AE) occurred in 82.7% of patients. Most common AEs were fatigue (58.3%) and anorexia (52.3%) which were graded as ≥ 3 in 8.2% and 7.4% of patients, respectively. CONCLUSION: Pazopanib is effective and well-tolerated in treatment of non-adipocytic metastatic STS. Its earlier use (at second-line), good performance status may result in better outcomes. Worldwide scientific collaborations are important to gain knowledge on rarer STS subtypes by conducting studies in larger patient populations.

BACKGROUND: Colorectal cancer (CRC) is a rare disease amongst children and adolescents. Previous studies have reported a number of differences between children/adolescents, young adults, and adult patients with CRC. However, none of these studies compared these age groups according to their clinicopathologic and prognostic characteristics. In the current study, we compare these three age groups. METHODS: A total of 173 (1.1% of 15,654 patients) young CRC patients (≤25 years) were included in the study. As a control group, 237 adult CRC patients (>25 years) were also included. Patients were divided into three age groups: child/adolescent (10-19 years), young adult (20-25 years), and adult (>25 years). RESULTS: Statistical differences amongst the three groups in terms of gender (p = 0.446), family history (p = 0.578), symptoms of presentation (p = 0.306), and interval between initiation of symptoms and diagnosis (p = 0.710) could not be demonstrated. Whilst abdominal pain (p < 0.001) and vomiting (p = 0.002) were less common in young adults than in other groups, rectal bleeding and changes in bowel habits were relatively less common in adolescents than in other groups. Rectal localisation (p = 0.035), mucinous adenocarcinoma (p < 0.001), and a poorly differentiated histologic subtype (p < 0.001) were less common in the adult group than in other groups. The percentage of patients with metastasis and sites of metastasis (e.g., peritoneum and lung) differed between groups. The median overall survival was 32.6 months in the adolescent group, 57.8 months in the young adult group and was not reached in the adult group (p = 0.022). The median event-free survival of the adolescent, young adult, and adult groups was 29.0, 29.9, and 61.6 months, respectively (p = 0.003). CONCLUSIONS: CRC patients of different age groups present different clinicopathologic and prognostic characteristics. Clinicians should be aware of and manage the disease according to these differences.

PURPOSE: Almost half of all patients diagnosed with non-small cell lung cancer (NSCLC) have distant metastases at presentation. One-third of patients with NSCLC will have brain metastases. Without effective treatment, the median survival is only 1 month. However, it is difficult to treat brain metastases with systemic chemotherapy since the agents have difficulty crossing the blood-brain barrier. Therefore, it is important to estimate the patient's survival prognosis. The aim of this study was to analyze prognostic factors for survival in Turkish patients who received chemotherapy after cranial irradiation for NSCLC with brain metastases. METHODS: We retrospectively reviewed 698 patients with brain metastases resulting from NSCLC. Ten potential prognostic variables were chosen for analysis. Univariate and multivariate analyses were conducted to identify prognostic factors associated with overall survival (OS). RESULTS: Among the 10 variables for univariate analysis, six were identified to have prognostic significance; these included sex, smoking history, histology, number of brain metastases, extracranial metastases, and neurosurgical resection. Multivariate analysis by the Cox proportional hazard model showed that a smoking history, extracranial metastases, and neurosurgical resection were independent negative prognostic factors for OS. CONCLUSION: Smoking history, extracranial metastases, and neurosurgical resection were considered independent negative prognostic factors for OS. These findings may facilitate pretreatment prediction of survival and can be used for selecting patients for more appropriate treatment options.

BACKGROUND: Currently, it is accepted that risk assessment of clinical stage I (CS I) nonseminomatous germ cell tumors (NSGCT) patient is mainly dependent on the presence of lymphovascular invasion (LVI). Initial active surveillance, adjuvant chemotherapy and retroperitoneal lymph node dissection (RPLND) are acceptable treatment options for these patients, but there is no uniform consensus. The purpose of this study was to compare outcomes of active surveillance with adjuvant chemotherapy. METHODS: A total of 201 patients with CS I NSGCT after orchiectomy were included. Outcomes of active surveillance and adjuvant chemotherapy were retrospectively analyzed. The prognostic significance of risk factors for survival and relapse was evaluated. RESULTS: Of the 201 patients, 110 (54.7%) received adjuvant chemotherapy, while the remaining 91 patients (45.3%) underwent surveillance. Relapses were significantly higher for patients underwent surveillance compared to adjuvant chemotherapy group (18.3 vs. 1.2%, p < 0.001). The 5-year relapse-free survival (RFS) rate for patients who were treated with adjuvant chemotherapy was significantly better than those of patients underwent surveillance (97.6 vs. 80.8%, respectively; p < 0.001). Univariate analysis showed that the presence of LVI (p = 0.01) and treatment option (p < 0.001) were prognostic factors for RFS and pT stage (p = 0.004) and invasion of rete testis (p = 0.004) and the presence of relapse (p < 0.001) were significant prognostic factors for OS. Multivariate analysis revealed that the treatment strategy was an independent prognostic factor for RFS (p < 0.001, HR 0.54). A logistic regression analysis demonstrated that treatment options (p = 0.031), embryonal carcinoma (EC) >50% (p = 0.013) and tumor diameter (p = 0.016) were found to be independent factors for predicting relapse. CONCLUSIONS: Our results indicate that adjuvant chemotherapy is associated with improved RFS compared with surveillance for CS I NSGCT patients. Moreover, the treatment strategy is an important prognostic indicator for RFS and a predictive factor for relapse. Although adjuvant chemotherapy seems to be a suitable treatment for patients with risk factors for relapse, surveillance is still preferred management option.

OBJECTIVE: Mutations in the p53 gene are the most commonly observed genetic abnormalities in malignancies. The purpose of this study was to assess the diagnostic value of serum anti-p53 antibody (Ab) along with the correlation between serum anti-p53 Ab level and quantitative positron emission tomography (PET) parameters such as maximum standardized uptake value (SUVmax), SUVave, metabolic tumor volume, total lesion glycolysis (TLG) and tumor size. METHODS: Serum anti-p53 Ab level was studied in three groups. Patients who underwent 18F-fluorodeoxyglucose (FDG) PET/computed tomography (CT) imaging for staging of previously diagnosed lung cancer constituted the first group, while patients who underwent 18F-FDG PET/CT imaging for evaluation of suspicious pulmonary nodules detected on thorax CT and did not show pathologic FDG accumulation (NAPN=pulmonary nodule with non avid-FDG) were enrolled in the second group. The third group consisted of healthy volunteers. RESULTS: Twenty-eight patients with lung cancer (median age: 62.5, range: 39-77years), 28 patients with NAPN (median age: 65, range: 33-79 years), and 24 healthy volunteers (median age: 62, range: 44-74 years) were enrolled in the study. The serum anti-p53 Ab level was low in healthy volunteers while it was higher in both lung cancer patients and NAPN patients (p<0.05). When serum anti-p53 Ab level and PET parameters were evaluated, there was no significant correlation between serum anti-p53 Ab level and SUVmax, SUVave, TLG, tumor volume and tumor size of patients with lung cancer (p>0.05). Besides, there was no significant difference between serum anti-p53 Ab level and lesion size of NAPN patients (p>0.05). CONCLUSION: It was determined that serum anti-p53 Ab levels are not significantly correlated with PET parameters, and that serum anti-p53 Ab levels increase in any benign or malignant lung parenchyma pathology as compared to healthy volunteers. These results indicate that this Ab cannot be used as a predictor of malignancy in a lung lesion.
RESUMEN
BACKGROUND/AIMS: This study aimed to examine whether UHRF-1 and p53 overexpression is a prognostic marker for gastric cancer. PATIENTS AND METHODS: Sixty-four patients with gastric cancer (study group) and 23 patients with gastritis (control group) were evaluated. Immunohistochemistry was used to examine expression of UHRF-1 and p53 in gastric cancers and a control group diagnosed with gastritis. RESULTS: The median age was 63 years (18-83 years) in the study group. UHRF-1 was positive in 15 (23%) patients with gastric cancer and fi ve (21.7%) patients with gastritis (P = 0.559). UHRF1 expression level in gastric cancer is more powerful than in gastritis (P = 0.046). Thirty-seven (61%) patients with gastric cancer and only one patient with gastritis were p53 positive (P < 0.001). After a median follow-up of 12 months (1-110), the 2-year overall survival rates were 55% and 30% in negative and positive p53, respectively (P = 0.084). Also, the 2-year overall survival rates were 45% and 53% in negative and positive UHRF-1, respectively (P = 0.132). CONCLUSION: According to this study, UHRF-1 and p53 were not prognostic factors for gastric cancer, whereas they may have a diagnostic value for differentiating between gastric cancer and gastritis.

OBJECTIVE: Typically, bone metastasis causes osteolytic and osteoblastic lesions resulting from the interactions of tumor cells with osteoclasts and osteoblasts. In addition to these interactions, tumor tissues may grow inside bones and cause mass lesions. In the present study, we aimed to demonstrate the negative impact of a tumor mass in a large cohort of patients with bone metastatic cancer. METHODS: Data from 335 patients with bone metastases were retrospectively reviewed. For the analysis, all patients were divided into three subgroups with respect to the type of bone metastasis: osteolytic, osteoblastic, or mixed. The patients were subsequently categorized as having bone metastasis with or without a tumor mass, and statistically significant differences in median survival and 2-year overall survival were observed between these patients (the median survival and 2-year overall survival were respectively 3 months and 16% in patients with a tumor mass and 11 months and 26% in patients without a tumor mass; p<0.001). RESULTS: According to multivariate analysis, the presence of bone metastasis with a tumor mass was found to be an independent prognostic factor (p=0.011, hazard ratio: 1.62, 95% confidence interval: 1.11-1.76). Bone metastasis with a tumor mass was more strongly associated with osteolytic lesions, other primary diseases (except for primary breast and prostate cancers), and spinal cord compression. CONCLUSION: Bone metastasis with a tumor mass is a strong and independent negative prognostic factor for survival in cancer patients.

BACKGROUND: Acute kidney injury is an important issue in chemotherapy receiving patients an neutrophil gelatinase-associated lipocalin has been proposed as a novel marker. We here aimed to assess the role of urinary levels for assessment after platin exposure. MATERIALS AND METHODS: Patients who had treated with cisplatin or carboplatin or oxaliplatin containg regimens were included in this study. Baseline and postchemotherapy serum urea, creatinine, urine neutrophil gelatinase-associated lipocalin and urine creatinine levels were determined. To avoid the effects of hydration during chemotherapy infusion the urinary neutrophil gelatinase-associated lipocalin/urine creatinine ratio was used to determine acute kidney injury. RESULTS: Of a total of 42 patients receiving platin compounds,14 (33.3%) received cisplatin containing regimens, 14 (33.3%) received carboplatin and 14 (33.3%) oxaliplatin. The median age was 60 (37-76) years. Nineteen of the patients (45.2%) had lung cancer, 12 (28.6%) colorectal cancer and 11 (26.2%) others. The median pre and post chemotherapy urine neutrophil gelatinase-associated lipocalin/urine creatinin ratio was 15.6 ng/mg and 35.8 ng/mg (p=0.041) in the cisplatin group, 32.5 ng/mg and 86.3 ng/mg (p=0.004) in the carboplatin group and 40.9 ng/mg and 62.3 ng/ mg (p=0.243) in the oxaliplatin group. CONCLUSIONS: Nephrotoxicity is a serious side effect of chemotherapeutic agentslike cisplatin and carbopaltin, but only to a lower extent oxaliplatin. All platin compounds must be used carefully and urine neutrophil gelatinase-associated lipocalin measurement seems to be promising in detecting acute kidney injury earlier than with creatinine.

BACKGROUND: The standard therapy for stage I rectum cancer is surgical resection. Currently, there is no strong evidence to suggest that any type of adjuvant therapy is beneficial. The risks of local relapse and distant metastasis are higher in rectal tumors. Therefore, while there is no clearly defined absolute indication for adjuvant therapy in lymph node negative colon cancers, rectum tumors that are T3N0 and higher require adjuvant treatment. Due to the more aggressive nature of rectal cancers, we explored the clinical and pathologic factors that could predict the risk of relapse in Stage I (T1-T2) disease and whether there was any progression-free survival benefit to adjuvant therapy. MATERIALS AND METHODS: This multicenter study was carried out by the Anatolian Society of Medical Oncology. A total of 178 patients with rectal cancers who underwent curative surgery between January 1994 and August 2012 in 13 centers were included in the study. Patient demographics, including survival data and tumor characteristics were obtained from medical charts. RESULTS: The median age was 58 years (range 26-85 years). Most tumors were well or moderately differentiated. For adjuvant treatment, 13 patients (7.3%) received radiotherapy alone, 12 patients (6.7%) received chemotherapy alone and 15 patients (8.4%) were given chemoradiotherapy. Median follow up was 29 months (3-225 months). Some 42 patients (23.6%) had relapse during follow up; 30 with local recurrence (71.4%) whereas 12 (28.6%) were distant metastases. Among the patients, 5-year DFS was 64% and OS was 82%. Mucinous histology and receiving adjuvant therapy were found to have statistically insignificant correlations with relapse and survival. CONCLUSIONS: In our retrospective analysis, approximately one quarter of patients exhibited either local or systemic relapse. The rates of relapse were slightly higher in the patients who had no adjuvant therapy. There may thus be a role for adjuvant therapy in high-risk stage I rectal tumors.

BACKGROUND: Breast cancer evolution and tumor progression are controlled by complex interactions between steroid receptors and growth factor receptor signaling. Aberrant growth factor receptor signaling can augment or suppress estrogen receptor function in hormone-dependent breast cancer cells. Thus, we aimed to investigate antitumor effects of sorafenib and lapatinib alone and in combination on MCF-7 breast cancer cells. MATERIALS AND METHODS: Cytotoxicity of the sorafenib and lapatinib was tested in MCF-7 cells by XTT assays. 50, 25, 12.5 and 6.25µM concentrations of sorafenib and 200, 100, 50 and 25µM concentrations of lapatinib were administered alone and in combination. Results were evaluated as absorbance at 450nM and IC50 values are calculated according to the absorbance data RESULTS: Both sorafenib and lapatinib showed concentration dependent cytotoxic effects on MCF-7 cells. Sorafenib exerted cytotoxic effects with an IC50 value of 32.0µM; in contrast with lapatinib the IC50 was 136.6µM. When sorafenib and lapatinib combined, lapatinib increased cytotoxic effects of sorafenib at its ineffective concentrations. Also at the concentrations where both drugs had cytotoxic effects, combination show strong anticancer effects and killed approximately 70 percent of breast cancer cells. CONCLUSIONS: Combinations of tyrosine kinase inhibitors and cytotoxic agents or molecular targeted therapy has been successful for many types of cancer. The present study shows that both sorafenib and lapatinib alone are effective in the treatment of breast cancer. Also a combination of these two agents may be a promising therapeutic option in treatment of breast cancer.

BACKGROUND: Osteosarcomas are the most common solid malignancies of bone. In the last two decades there have been no concrete developments in their systemic treatment. In this trial we aimed to present our osteosarcoma patient clinical and demographic outcomes. MATERIALS AND METHODS: Patients treated and followed up for osteosarcoma in Ankara Numune Education and Research Hospital from 2002 to 2012 were reviewed retrospectively. RESULTS: A total of 21 patients (15 male, 6 female) were diagnosed with osteosarcoma. The disease was located at extremities in 76% and in 14% was metastatic at the time of diagnosis. Median disease free survival (DFS) was 36 months in non-metastatic patients and median progression free survival (PFS) was 2 months in metastatic patients (p<0.0001). Median overall survival (OS) was 80 months and 4 months, respectively (p=0.012). There were no survival differences in terms of presentation with pathological fracture, tumor size, tumor grade, alkaline phosphatase and lactate dehydrogenase level and type of chemotherapy regimen. CONCLUSIONS: Tumor site and stages are the most important prognostic factors for osteosarcoma. Extremity primary tumors have beter survival rates than non-extremity tumors. As a result of the use of effective chemotherapy the long term survival rates have improved from 10-20% to 60-70% in the last decades but we need more active agents, especially for metastatic cases.

BACKGROUND: Lung cancer is the most common cause of cancer-related death worldwide. The incidence of lung cancer is aproximately 7-8 thousand percent in Turkish women. In this study, we aimed to evaluate the clinical, pathological properties and survival data of female patients with lung cancer who were treated in our center. MATERIALS AND METHODS: From 2007 to 2012, 50 women with lung cancer were enrolled. Patient data were evaluated retrospectively. RESULTS: The median age was 61 (40-81). Forty patients (80%) were diagnosed with non small cell lung cancer (NSCLC), 10 patients (20%) were small cell carcinoma (SCC). Twelve (24%) patients were smokers and 13 of 16 non-smokers had a history of exposure to asbestos. The most common histologic subtype was adenocarcinoma (46%) and this accounted for 71% in patients with exposure to asbestos. The most common initial Eastern Cooperative Oncology Group (ECOG) performance score was 1 (24 patients, 48%) and initial stage was IV (25 patients, 50%) in the study group. During the median 15 months (1-96 months) followup period: 1 year overall survival (OS) was 68%, 2year overall survival was 36% and the median survival time was 19 months. According to univariate analysis, poor ECOG performance status, advanced stage, anemia and weight loss at time of diagnosis were negative prognostic factors. However, adenocarcinoma sub-type was a positive prognostic factor. CONCLUSIONS: In this study NSCLC sub-type, poor ECOG performance score, advanced stage, anemia and weight loss were prognostic factors in Turkish women with lung cancer.

BACKGROUND: Ewing sarcoma is a small round cell tumor arising from soft tissue and bone that predominantly affects children and adolescents. The most unfavorable prognostic factor is the presence of distant metastasis at the time of diagnosis. MATERIALS AND METHODS: The records of 26 Ewing sarcoma patients (14 male, 12 female) were re-evaluated retrospectively. RESULTS: The median age was 26.5 (19-42) years. Eight patients (31%) showed a primary tumor in their extremities, 8 (31%) in the thorax, 4 (15%) at the vertebra, 4 (15%) in the head and neck, and 2 (8%) in the abdomen. Five patients (19%) had distant metastasis at diagnosis. The median progression-free survival was 72 months and 10 months in localized and metastatic disease, respectively (p=0.005). The overall survival rate was 19 months in metastatic disease, and the 5-year overall survival rate was 64% in localized disease (p=0.006). Patients who had localized disease in the extremities and were under age 30 had a favorable prognosis. CONCLUSIONS: Although Ewing sarcoma is a tumor affecting children and adolescents, it may be seen in adults, where the prognosis is generally worse. Although it is a highly malignant tumor, it is possible to achieve improved survival with combined modality treatments.

BACKGROUND: This study aimed to determine the demographical distribution, survival and prognostic factors for neuroendocrine tumors monitored in our clinic. MATERIALS AND METHODS: Data for 52 patients who were admitted to Cumhuriyet University Medical Faculty Training Research and Practice Hospital Oncology Center between 2006 and 2012 and were diagnosed and treated for neuroendocrine tumors were investigated. RESULTS: Of the total, 30 (58%) were females and 22 (42%) were males. The localization of the disease was gastroenteropancreatic in 29 (56%) patients and other sites in 23 (44%). The most frequently involved organ in the gastroenteropancreatic system was the stomach (n=10, 19%) and the most frequently involved organ in other regions was the lungs (n=10, 19%). No correlation was found between immunohistochemical staining for proteins such as chromogranin A, synaptophysin, and NSE and the grade of the tumor. The patients were followed-up at a median of 24 months (1-90 months). The three-year overall survival rate was 71%: 100% in stage I, 88% in stage II, 80% in stage III, and 40% in stage IV. The three-year survival rate was 78% in tumors localized in the gastroenteropancreatic region, and 54% in tumors localized in other organs. In the univariate analysis, gender, age, performance status of the patients, grade, localization, surgical treatment, and neutrophil/ lymphocyte ratio (≤ 5 versus >5) affected the prognosis of the patients. CONCLUSIONS: Most of the tumors were localized in the gastroenteropancreatic region, and the three-year survival rate in tumors localized in this region was better than the tumors localized in other sites. Surgical treatment was a positive independent prognostic factor, whereas Grade 3 and a neutrophil/lymphocyte ratio of >5 were negative independent prognostic factors.

BACKGROUND/AIM: Oxaliplatin is an effective and widely used chemotherapeutic agent in the treatment of many solid tumors. The most common side effects are peripheral neuropathy, gastrointestinal toxicity, and neutropenia. There have been some case reports about ototoxicity with oxaliplatin, but no clinical trials. In this trial, we explored whether or not oxaliplatin has ototoxic effects. MATERIALS AND METHODS: A total of 18 patients, 14 with colorectal cancer and 4 with pancreatic cancer, were included in this study. Four patients (22%) were treated with a capecitabine and oxaliplatin (CapeOx) regimen, and 14 patients (78%) were treated with fluorouracil, leucovorin, and oxaliplatin (FOLFOX-6). Patients' pretreatment and posttreatment hearing levels were assessed with high-frequency audiometry and otoacoustic emission tests. RESULTS: The median time between the first and the last oxaliplatin doses was 3.2 months (range: 2-7 months). There was no hearing loss in tests conducted for both ears of patients at frequencies of 500, 1000, 2000, 4000, 6000, 8000, 12,000, and 16,000 Hz. There was no difference between the pretreatment and posttreatment otoacoustic emission tests. CONCLUSION: Oxaliplatin is a reliable agent in terms of ototoxicity.

Endocervical stromal sarcoma (ECSS) is a very rare uterine sarcoma. The most common presentation is pelvic mass and vaginal bleeding. The mainstay of treatment is surgery. There is no consensus on the adjuvant treatment. Relapses are usually in the pelvic and abdominal regions. To a lesser extent, lung, liver and bone metastases may be seen. A 46-year-old woman had total abdominal hysterectomy (TAH) with bilateral salpingo-oophorectomy (BSO) performed due to endometrial polyp and leiomyoma. Six months after the TAH-BSO, she was admitted to the hospital with cough and hemoptysis. A thoracic mass was detected, and a biopsy was done. The diagnosis was low-grade ECSS metastasis. One week after thoracotomy, she was admitted to the hospital with loss of vision in the left eye. An orbital mass was detected with magnetic resonance imaging. Endometrial and cervical pathology preparations were reassessed and were compatible with ECSS. We performed mammography, thorax, and abdomen and cranial imaging to rule out other malignancies that may cause lung and orbital metastasis. Partial remission was achieved with systemic chemotherapy and orbital radiotherapy. Orbital metastasis may be seen in ECSS patients. Although we have less knowledge about the choice of chemotherapeutic agents, ifosfamide and doxorubicin are effective in treating ECSS.
RESUMEN
The aim of this retrospective, multicenter study was to evaluate clinicopathological characteristics, prognostic factors and treatment outcomes of teenage and adult patients with high-grade osteosarcoma. A total of 240 osteosarcoma patients who were diagnosed and treated from March 1995 to September 2011 were analyzed. Median age was 20 years (range 13-74 years), and 153 patients (63.8%) were male. Primary tumor localization was extremity in 204 patients (85.4 %), trunk in 21 patients (8.8%) and head and neck region in 14 patients (5.9%). According to American Joint Committee on Cancer staging system, 186 patients (77.5%) were stage II, 3 (1.3%) were stage III and 48 (20.0%) were stage IV. Median overall survival (OS) was 55 months (95 % CI 36.8-73.1 months). OS after 2, 5 and 10 years were 67, 49 and 42%, respectively. Univariable analysis for OS showed that male gender (p = 0.032), high baseline lactate dehydrogenase (LDH) level (p < 0.001), high baseline serum alkaline phosphatase level (p = 0.002), telangiectatic subtype (p = 0.023), presence of metastasis at diagnosis (p < 0.001), presence of tumor positive margins after primary surgery (p = 0.015), poor pathological response to preoperative chemotherapy (p = 0.006) and presence of recurrent disease during follow-up period (p < 0.001) were significantly associated with poor survival. Patients who received postoperative methotrexate plus doxorubicin plus cisplatin (M + A + P) combination regimen (p = 0.019), underwent surgery for recurrent disease (p < 0.001) and received chemotherapy for recurrent disease (p < 0.001) had longer OS. In multivariable analysis for OS, only high LDH level (p = 0.002) and the presence of metastasis at diagnosis (p = 0.011) were associated with poor OS, whereas the patients who received chemotherapy for recurrent disease had a longer OS (p = 0.009).

PURPOSE: Excision repair cross-complementation group 1 enzyme (ERCC1) plays a key role in the removal of platinum induced DNA adducts and cisplatin resistance. Prognostic role of ERCC1 expression in the neoadjuvant setting in bladder cancer has not been reported before. We evaluated the prognostic role of ERCC1 expression in bladder cancer receiving platinum-based neoadjuvant chemotherapy. MATERIALS AND METHODS: Thirty-eight patients with muscle invasive bladder cancer who received neoadjuvant platinum-based chemotherapy were included. Clinical and histopathologic parameters along with immunohistochemical ERCC1 staining were examined and correlated with response rates and survival. RESULTS: Pathologic complete response rates were similar between patients with low and high ERCC1 expression. Median disease-free survival (DFS) was 9.3 vs. 20.5 months (P = 0.186) and median overall survival (OS) was 9.3 vs. 26.7 months (P = 0.058) in patients with high ERCC1 expression compared with those with low expression, respectively. In multivariate Cox regression analysis: pathological complete response (pCR) after chemotherapy (hazard ratio (HR) 0.1, 95% CI 0.012-0.842, P = 0.034) and high ERCC1 expression (HR 3.7, 95% CI 1.2-11.2, P = 0.019) were significantly associated with DFS. Patient age (>60 vs. ≤ 60 years) (HR 3.4, 95% CI 1.2-9.4, P = 0.018), the presence of pCR (HR 0.11, 95% CI 0.014-0.981, P = 0.048) and high ERCC expression (HR 6.1, 95 CI 1.9-19.9, P = 0.002) were significantly associated with OS. CONCLUSIONS: Our results showed that high ERCC1 expression was independently associated with shorter disease-free and overall survival in patients with bladder cancer who received neoadjuvant platinum-based chemotherapy. ERCC1 may represent a potential predictive marker for platinum-based treatment in bladder cancer.
