RESUMO
Skeletal-related events (SREs) for nonsmall cell lung cancer (NSCLC) patients with bone metastasis lead to serious morbidity. The aim of this study was to determine risk factors for SREs in NSCLC patients with bone metastasis and the factors influencing SRE-free survival and overall survival (OS). From 2000 to 2012, we evaluated retrospectively 835 NSCLC patients. Three hundred and thirty-five of them with bone metastasis were included in the study. SREs and the other prognostic factors were evaluated by univariate and multivariate analysis for SRE-free survival and OS. SREs were detected in 244 patients (72.8 %). The most common SREs were the need for radiotherapy (43.2 %) and malignant hypercalcemia (17.6 %). The median time to first SRE was 3.5 months at the median follow-up of 17 months. A multivariate analysis showed that the presence of bone metastasis at diagnosis (p < 0.001), the number of bone metastasis (p = 0.001), baseline hypercalcemia (p = 0.004), and the presence of palliative radiotherapy (p = 0.04) were independent prognostic factors for SRE-free survival. A logistic regression analysis identified that the presence of bone metastasis at diagnosis [odds ratio (OR), 12.6], number of bone metastasis (OR, 3.05), and baseline hypercalcemia (OR, 0.33) were found to be predictive factors in the developing of SRE. The median OS time for patients with SRE was worse than that for patients without SRE (7 vs 12 months, respectively). For OS, male gender, ECOG performance status (PS), high lactate dehydrogenase (LDH) level, hypoalbuminemia, the presence of bone metastasis at diagnosis, the number of bone metastasis, the presence of SREs, the presence of bisphosphonate therapy, and palliative radiotherapy were independent prognostic indicators for OS by the multivariate analysis. Our results indicated that the frequency of SREs was high and the presence of bone metastasis at the time of diagnosis, baseline hypercalcemia, and multiple bone metastases were significant factors predicting the occurrence of SREs. If bone metastases diagnose earlier, treatments for the prevention of SREs may be initiated earlier; thus, the deterioration of quality of life may be preserved.

Patients with advanced non-small cell lung cancer (NSCLC) generally require second-line treatment although their prognosis is poor. In this multicenter study, we aimed to detect the characteristics related to patients and disease that can predict the response to second-line treatments in advanced NSCLC. Data of 904 patients who have progressed after receiving first-line platinum-based chemotherapy in 11 centers with the diagnosis of stage IIIB and IV NSCLC and who were evaluated for second-line treatment were retrospectively analyzed. The role of different factors in determining the benefit of second-line treatment was analyzed. Median age of patients was 57 years (range 19-86). Docetaxel was the most commonly used (20.9 %, n = 189) single agent, while gemcitabine-platinum was the most commonly used (6.7 %, n = 61) combination chemotherapy regimen in second-line setting. According to survival analysis, median progression-free survival after first-line treatment (PFS2) was 3.5 months (standard error (SE) 0.2; 95 % confidence interval (CI), 3.2-3.9), median overall survival (OS) was 6.7 months (SE 0.3; 95 % CI, 6.0-7.3). In multivariate analysis, independent factors affecting PFS2 were found to be hemoglobin (Hb) level over 12 g/dl and treatment-free interval (TFI) longer than 3 months (p = 0.006 and 0.003, respectively). Similarly, in OS analysis, Hb level over 12 g/dl and time elapsed after the first-line treatment that is longer than 3 months were found to be independent prognostic factors (p = 0.0001 and 0.045, respectively). In light of these findings, determining and using the parameters for which the treatment will be beneficial prior to second-line treatment can increase success rate.

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.

INTRODUCTION: Sunitinib is an oral inhibitor of tyrosine kinase that was used for the treatment of mRCC. The general side effects are fatigue, asthenia, diarrhea, mucositis, nausea, vomiting, skin changes, hypertension, hypothyroidism and hematologic side effects. In addition, sunitinib-induced hypoglycemia has also been reported. There are limited number of case reports related to sunitinib-induced hypoglycemia. CASE PRESENTATION: In this case report, we have presented a patient with type 2 diabetes mellitus (DM) with emerging severe hypoglycemia after sunitinib treatment. It was shown that blood glucose levels were normalized two weeks after the interruption of sunitinib. CONCLUSION: Although the underlying mechanism of sunitinib-induced hypoglycemia is not completely understood, sunitinib can be regarded to have an antidiabetic effect. In the literature, there are some reports about sunitinib/other TKI induced hypoglycemia; however, life threatening hypoglycemia is rare. There is no case report of severe hypoglycemia due to imatinib; however, there are two case reports with severe hypoglycemia due to sunitinib treatment. Symptomatic hypoglycemic episodes due to sunitinib may lead to hospital admission. Diabetic patients may develop severe hypoglycaemia and it should be kept in mind that the discontinuation of antihyperglycemic treatment may be required. Therefore, blood glucose levels should be closely monitored in diabetic patients with mRCC during sunitinib therapy.

PURPOSE: Registry of Gastric Cancer Treatment Evaluation (REGATE) study was an international, prospective study including over 10000 patients from 22 countries, designed to describe the pattern of care in gastric cancer globally. The aim of this study was to summarize the data of the Turkish arm and compare them with the global results. METHODS: Ten centers from Turkey took part in the REGATE registry. Between 2004 and 2008, 395 patients (median age, 60 years; range, 18-91, 67.6% men) with newly diagnosed primary adenocarcinoma of the stomach were followed at initial visit and 8-10 months later, at the time of treatment completion. Data on patient demographics, medical history, histopathology, cancer stage, planned and realized treatments was prospectively collected. Data processing and analysis were conducted centrally. RESULTS: In Turkey, the majority of patients were diagnosed at an advanced stage, while the rate of surgery was lesser compared with the rest of the world. Realized treatment included more palliative-only therapy than initially planned (63.3%), while no therapy was recommended in 21.8%. Surgery involved total gastrectomy (46.3%) or distal subtotal gastrectomy (51.9%), with 87% R0 resection, 51.0% D1 and 44.9% D2 lymph node dissection. Combination chemotherapy was administered in more than half of the patients receiving palliative therapy (57.9%). Chemoradiotherapy was used in 66.7% of the cases receiving adjuvant therapy. Radiotherapy was applied to 32% of the cases receiving palliative therapy. CONCLUSION: Advanced stage gastric cancer is highly prevalent in Turkey. Increasing public awareness and implementing screening programs in high risk groups may help identify gastric cancer at earlier stages.

OBJECTIVE: The aim of this study was to assess the use of 5-fluorouracil (5-FU), leucovorin and oxaliplatin (FOLFOX) regimens in clinical practice according to their efficacy and toxicity. METHODS: Patients who received oxaliplatin-containing regimens after curative resection for colorectal carcinoma from 10 different oncology centers between May 2004 and December 2009 were included in the study. All patients were treated with FOLFOX regimens. Patients with rectal carcinoma were also treated with chemoradiotherapy with 5-FU after 2 cycles of a FOLFOX regimen. RESULTS: The median age of the patients was 56 years (range 17-78). Of the total 667 patients, 326 were given FOLFOX-4, 232 were given modified FOLFOX-4 and 109 were given FOLFOX-6. The distribution according to disease stage was 33 patients with stage IIIA colorectal cancer, 382 patients with stage IIIB and 252 patients with stage IIIC. The most common adverse events were neutropenia (54%), nausea (36.9%), neuropathy (38.2%) and anemia (33.1%) for all grades. The median follow-up time was 23 months (range 1-79). Three-year disease-free survival and overall survival were 65 and 85.7%, respectively. CONCLUSION: The different oxaliplatin-containing 5-FU-based adjuvant chemotherapy regimens in patients with stage III colorectal cancer seemed to be at least equal in terms of efficacy regardless of the method of 5-FU administration or oxaliplatin dose.

BACKGROUND/AIMS: The aims of this study were to report the clinical outcomes of adjuvant chemo-radiotherapy after curative resection in 637 patients with gastric cancer. METHODOLOGY: The retrospective analysis included 637 patients with resectable gastric cancer and stage IB-IV (M0) from 8 medical centers between 2003 and 2010. The patients were treated with 5FU-leucovorin and radiotherapy according to Schema for INT-0116. RESULTS: Of the 637 patients, the median of overall survival (OS) was 43.7 months and relapse free survival (RFS) was 36.6 months. OS rates were 84%, 45%, 40% while RFS rates were 81%, 45% and 35% at 1, 3 and 5-years, respectively. Hematological and gastrointestinal toxicities (grade 1-4) were observed in 35% and 36.5% of patients, respectively. In univariate analysis, according to the Lauren classification, tumor grade, T stage, N stage, type of operation (total gastrectomy or subtotal) and surgery resection margin (R0 or R1) were found as prognostic factors on RFS and OS (p<0.05). In multivariate analysis, T stage, N stage and surgical margins were found as effective factors on OS. T stage, N stage and Lauren classification were factors affecting RFS. CONCLUSIONS: Adjuvant chemo-radiotherapy after curative resection of gastric cancer was feasible, with acceptable toxicities in the Turkish population.

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.

BACKGROUND: Bisphosphonates are the mainstay therapeutic options for prevention of skeletal-related events and generally used for up to 2 years in bone metastatic cancer patients. AIM: We aimed to evaluate the long-term outcomes of prolonged (> 2 years) bisphosphonate usage in bone metastatic breast cancer (BMBC) patients. METHODS: Ninety-nine BMBC patients who had prolonged bisphosphonates were evaluated retrospectively for long-term outcomes and survival rates. RESULTS: Median duration of bisphosphonate therapy was 46.8 (24-198) months. Seven patients had bisphosphonate-related adverse events (osteonecrosis of the jaw (ONJ) (n = 6), ONJ and renal failure (n = 1)). Bisphosphonate was switched to another one because of bone metastasis progression in more than one-third of the patients (n = 36, 36.3%). The patients who had bisphosphonate switch therapy had statistically significant longer overall survival (p < 0.01). Neither duration nor type of bisphosphonates had effect on frequency of bisphosphonate-related adverse events. CONCLUSION: Bisphosphonates might be prolonged for more than 2 years in BMBC patients with an acceptable toxicity profile. In addition, bisphosphonates switch therapy should be preferred in those with progressive bone metastasis since it might contribute to better survival despite bisphosphonates could not have been shown to have survival benefit in previous studies.

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.

BACKGROUND: We retrospectively evaluated the activity and toxicity of uracil/tegafur (UFT) plus oral folinic acid in combination with vinorelbine (alternating intravenous (IV) on day 1 and oral on day 8) in patients with metastatic breast cancer. PATIENTS AND METHODS: Treatment consisted of IV vinorelbine 25 mg/m(2) on day 1 and 60 mg/m(2) orally on day 8, and oral UFT 300 mg/m(2) plus leucovorin 60 mg/m(2) on days 1-14 with 21 days interval. All patients were refractory to anthracyclines and taxanes. RESULTS: Partial response (PR) was observed in 3 (9.7%) and stable disease (SD) was observed in 13 (41.9%) patients. Total clinical benefit (PR + SD) of the combination was 51.6%. The median response duration was 3 (range 1-11.8) months. Median overall survival was 9.8 months (95% confidence interval (CI): 7.5-12.1), and median time to progression was 3.4 months (95% CI: 2.3-4.5). The most common toxicities were hematologic, including 4 (12.9%) cases of grade 3 neutropenia and 4 (12.9%) cases of grade 4 neutropenia. Grade 3 diarrhea was reported in 2 (3.2%) patients. 3 (9.7%) patients had hand-foot syndrome. Febrile neutropenia was observed in 1 patient. CONCLUSIONS: Although the combination is safe and convenient in clinical practice, it has only moderate activity in metastatic breast cancer patients.

The aim of the study was to evaluate the efficacy and tolerability of gemcitabine and uracil-tegafur (UFT) combination in patients with advanced pancreatic carcinoma, retrospectively. Thirty-one patients, including 27 with metastatic disease, were treated with gemcitabine at a dose of 1000 mg/m2 in 30 minutes on days 1 and 8, and oral UFT 300 mg/m2 on days 1-14, as the first-line regimen in advanced stage. The cycle was repeated every 21 days. A total of 116 cycles of chemotherapy were administered, with a median of 3 cycles per patient (range 1-13). The objective response rate was observed in 6 (19.3%) patients with 1 (3.2%) complete response, and 5 (16.1%) partial responses. The median response duration was 4 (range, 3-14) months. Eight (25.8%) patients had a standard deviation of more than 3 months. Median overall survival was 8 months (95% CI, 6-10 months) and median time to progression was 4.2 months (95% CI, 1-6 months). This combination was generally well tolerated. There were no life-threatening side effects. Most common toxicities were of hematologic and gastrointestinal nature. In conclusion, this regimen was well tolerated and seemed to have a moderate activity in the palliative treatment of advanced pancreatic carcinoma.

OBJECTIVE: Hepatocellular cancer (HCC) is one of the important health problems in Turkey. We aimed to determine the clinical and demographic features of HCC in the Turkish population and to evaluate the prognostic and survival features. METHOD: Two hundred and twenty-one patients with HCC from five hospitals in Turkey are included in this study. RESULTS: In 44.4% of the 221 patients with hepatitis B virus and in 21.3% of the 221 patients with hepatitis C virus were found to be responsible for HCC etiology. It has been shown that HCC developed on cirrhosis basis in 74.2% of the patients. HCC was presented with single solitary nodule in 69.2% of the patients. Non-liver metastasis was present in 12.5% of the patients. In 21.7% of the patients, alpha-fetoprotein (AFP) levels were above the diagnostics level of 400 ng/ml. The median overall survival (OS) of 221 patients was 14 months. The median OS of the patients with Child-Pugh A class was significantly longer than that with Child-Pugh B and C classes. The OS of the individuals with normal AFP levels was also longer than that with high AFP levels. The OS of the patients with Stage I HCC according to tumor node metastasis (TNM) classification, the female patients and the treated patients group was found to be significantly good. CONCLUSIONS: In conclusion, the viral etiology (hepatitis B and C infections) in Turkish population is found to be an important factor in HCC development. The Child-Pugh classification, AFP levels, TNM classification, being female and treatment were determined to be important prognostic factors in HCC patients.

AIM: The goal of this study is to evaluate possible factors affecting the survival of patients treated with gonadotropin-releasing hormone (GnRH) analogues. METHODS: Demographic characteristics, treatment modalities, overall survival (OS) and the possible factors affecting the survival a total of 554 premenopausal breast cancer patients in Turkey evaluated retrospectively. RESULTS: The median duration of GnRH analogues use was 22 ± 13.6 (range, 1-87) months. Patients were divided into three groups according to the duration of GNRH analogues use; 4-12 months (Group A), 13-24 months (Group B) and ≥25 months (Group C). Overall, 530 patients were analyzed; 23.2%, 45.8%, 30.9% of the patients were in Group A, B and C, respectively. The median follow-up duration was 34 ± 30.3 (range, 4-188) months. The OS in patients ≤35 years of age was found to be significantly longer than that of patients >35 years of age in Group B (log rank, P = 0.023). The disease-free survival of the patients in Group A was significantly shorter than that of patients in Group C (log rank, P = 0.003). The OS of Group A patients was significantly shorter in comparison to that of Group B and Group C patients (log rank, P = 0.000) and the OS of Group B patients was significantly shorter than Group C (log rank, P = 0,000). CONCLUSION: There is currently no definite data on the optimal duration of GnRH analogues use. One of the important results of this study that will provide an insight to the future studies is the improvement gained in OS by the increase in the duration of GnRH analogues use.

BACKGROUND: Treatment of patients with metastatic breast cancer (MBC) exposed to anthracyclines and taxanes is challenging. Effective and well-tolerated regimens are required. Gemcitabine plus capecitabine combination was assessed in MBC patients pretreated with anthracyclines and taxanes. PATIENTS AND METHODS: A total of 31 patients treated between November 2004 and September 2005 were retrospectively evaluated in 4 institutions. The median age was 48 years (range 29-77). The patients were given gemcitabine 1,000 mg/m(2) on days 1 and 8, and capecitabine 1,500 mg/m(2) twice daily on days 1-14 every 3 weeks. RESULTS: A total of 160 cycles of chemotherapy were administered with a median of 5 cycles per patient (range 2-12). Three patients achieved a partial response (10%) and 8 patients (26%) stable disease. The median time to disease progression was 6 months (95% CI 5-7), with a median survival of 18 months (95% CI 15-21) at a median follow-up of 16 months (range 2-28). One-year and 2-year survival rates were 67 and 28%, respectively. Grade 3-4 toxicities were as follows: neutropenia (n = 11, 35%), nausea and vomiting (n = 4, 13%), hand-foot syndrome (n = 2, 6%), anemia (n = 2, 6%), thrombocytopenia (n = 2, 6%) and asthenia (n = 1, 3%). CONCLUSION: The combination of gemcitabine plus capecitabine was a tolerable regimen with a mild but comparable survival efficacy to similar regimens in patients with MBC after anthracyclines and taxanes.

Osteosarcomas with lung metastases are rather heterogenous group. We aimed to evaluate the clinicopathological characteristics and outcomes of osteosarcoma patients with lung metastases and to compare the synchronous and metachronous lung metastatic groups. A total of 93 adolescent and adult patients with lung metastatic osteosarcoma, from March 1995 to July 2011, in a single center, were included. Sixty-five patients (69.9%) were male. The median age was 19 years (range, 14-74). Thirty-nine patients (41.9%) had synchronous lung metastases (Group A) and 54 patients (58.1%) had metachronous lung metastases (Group B). The 5-year and 10-year post-lung metastases overall survival (PLM-OS) was 17% and 15%, respectively. In multivariate analysis for PLM-OS, time to lung metastases (p = 0.010), number of metastatic pulmonary nodules (p = 0.020), presence of pulmonary metastasectomy (p = 0.007) and presence of chemotherapy for lung metastases (p< 0.001) were found to be independent prognostic factors. The median PLM-OS of Group A and Group B was 16 months and 9 months, respectively. In Group B, the median PLM-OS of the patients who developed lung metastases within 12 months was 6 months, whereas that of the patients who developed lung metastases later was 16 months. Time to lung metastases, number and laterality of metastatic pulmonary nodules, chemotherapy for lung metastatic disease and pulmonary metastasectomy were independent prognostic factors for patients with lung metastatic osteosarcoma. The best PLM-OS was in the subgroup of patients treated both surgery and chemotherapy. The prognosis of the patients who developed lung metastases within 12 months after diagnosis was worst.

PURPOSE: In this study, we aimed to evaluate the effects of sex-based non-small cell lung cancer (NSCLC) varieties on survival rates. MATERIALS AND METHODS: A retrospective study was performed in patients with NSCLC who were diagnosed by histological methods between the years 2000 and 2010. A chi-square test was used to compare variables. Overall survival (OS) was estimated by the Kaplan-Meier method. RESULTS: Of the 844 patients, 117 (13.9%) were women and 727 (86.1%) were men. Adenocarcinoma was more common in women than in men (p<0.0001). There were more women non-smokers than men (p<0.0001). There was no statistically significant difference in ECOG PS, weight loss>10%, stage, LDH, albumin and treatment between women and men. Women younger than 65 years (17.0 vs 12.0 months; p=0.03), who had adenocarcinoma histology (15.0 vs 10.0 months; p=0.006) and who had a hemoglobin level≥12 g/dL (18.0 vs 12.0 months; p=0.01) were found to have a better median OS rate than men. Median OS rates were found to be 13.0 months in females and 12.0 months in males (p=0.14). Among metastatic patients, the median OS was 11.0 months in females and 8.0 months in males (p=0.005). Among stage IIIB and stage IV patients who had first line platinum-based chemotherapy, the median OS was 17.0 months in women and 11.0 months in men (p=0.002). The response rate of chemotherapy was higher in women than in men (p=0.03). CONCLUSIONS: In our study, we found that survival duration is longer and chemotherapy response is better in women with NSCLC who do not have anemia or comorbidities and who are mostly non-smokers with adenocarcinomas. Further studies regarding the causes of these differences may provide clarity on this subject.

PURPOSE: We aimed to establish a laboratory prognostic index (LPI) in advanced non-small cell lung cancer (NSCLC) patients based on hematologic and biochemical parameters and to analyze the predictive value of LPI on NSCLC survival. PATIENTS AND METHODS: The study retrospectively reviewed 462 patients with advanced NSCLC diagnosed between 2000 and 2010 in a single institution. We developed an LPI that included serum levels of white blood cells (WBC), lactate dehydrogenase (LDH), albumin, calcium, and alkaline phosphatase (ALP), based on the results of a Cox regression analysis. The patients were classified into 3 LPI groups as follows: LPI 0: normal; LPI 1: one abnormal laboratory finding; and LPI 2: at least 2 abnormal laboratory findings. RESULTS: The median follow up period was 44 months; the median overall survival (OS) and median progression-free survival (PFS) were 11 and 6 months, respectively. A multivariate analysis revealed that the following could be used as independent prognostic factors: an Eastern Cooperative Oncology Group performance status score (ECOG PS) ≥2, a high LDH level, serum albumin <3 g/dL, serum calcium>10.5 g/dL, number of metastases>2, presence of liver metastases, malignant pleural effusion, or receiving chemotherapy ≥4 cycles. The 1-year OS rates according to LPI 0, LPI 1, and LPI 2 were 54%, 34%, and 17% (p<0.001), respectively and 6-month PFS rates were 44%, 27%, and 15% (p<0.001), respectively. The LPI was a significant predictor for OS (Hazard Ratio (HR): 1.41; 1.05-1.88, p<0.001) and PFS (HR: 1.48; 1.14-1.93, p<0.001). CONCLUSION: An LPI is an inexpensive, easily accessible and independent prognostic index for advanced NSCLC and may be helpful in making individualized treatment plans and predicting survival rates when combined with clinical parameters.

BACKGROUND: Predictor factors determining complete response to treatment are still not clearly defined. We aimed to evaluate clinicopathological features, risk factors, treatment responses, and survival analysis of patient with advanced nonseminomatous GCTs (NSGCTs). MATERIALS AND METHODS: Between November 1999 and September 2011, 140 patients with stage II and III NSGCTs were referred to our institutions and 125 patients with complete clinical data were included in this retrospective study. Four cycles of BEP regimen were applied as a first-line treatment. Salvage chemotherapy and/or high-dose chemotherapy (HDCT) with autologous stem cell transplantation were given in patients who progressed after BEP chemotherapy. Post-chemotherapy surgery was performed in selected patients with incomplete radiographic response and normal tumor markers. RESULTS: The median age was 28 years. For the good, intermediate and poor risk groups, compete response rates (CRR) were, 84.6%, 67.9% and 59.4%, respectively. Extragonadal tumors, stage 3 disease, intermediate and poor risk factors, rete testis invasion were associated with worse outcomes. There were 32 patients (25.6%) with non-CR who were treated with salvage treatment. Thirty-one patients died from GCTs and 94% of them had stage III disease. CONCLUSIONS: Even though response rates are high, some patients with GCTs still need salvage treatment and cure cannot be achieved. Non-complete response to platinium-based first-line treatment is a negative prognostic factor. Our study confirmed the need for a prognostic and predictive model and more effective salvage approaches.
