RESUMO
Objective: Hormone positive breast cancer is a tumor with high mortality. Combining antihormonal therapy with cyclin dependent kinase 4/6 inhibitors (CDK4/6i) has resulted in longer survival. The effect of inflammatory parameters such as c-reactive protein and c-reactive protein/lymphocyte ratio (CLR) on efficacy and survival in CDK4/6i treatment is unknown. In our study, we aimed to investigate the role of CLR and some parameters in predicting progression-free survival (PFS) with CDK4/6i. Methods: This retrospective cohort study included 78 patients with denovo and recurrent metastatic breast cancer treated with CDK4/6i. Cut off values for the prediction of mortality by various numerical parameter scores were performed by ROC Curve analysis. The effect of clinical variables, inflammatory and histopathological parameters on survival was analyzed by Kaplan-Meier method. Results: Neutrophil/lymphocyte ratio (NLR) and CLR were statistically significant in predicting mortality (p < 0.05). Ki67 and CLR were correlated with PFS. Age and CLR were correlated with OS (p < 0.05). CLR was statistically significant for both PFS (p = 0.022) and OS (p = 0.006). Conclusion: In patients with metastatic hormone-positive breast cancer using CDK4/6i, low CLR and low Ki67 were correlated with longer PFS duration.
RESUMO
OBJECTIVES: Head and neck cancers (HNCs) represent a significant global health concern due to high morbidity and mortality rates. Despite therapeutic advances, the prognosis for advanced or recurrent cases remains challenging. Nivolumab obtained approval for recurrent or metastatic HNC based on the Phase III CheckMate 141 trial. This study aimed to evaluate the real-world outcomes of nivolumab in patients with non-nasopharyngeal HNC. DESIGN: In this multicenter retrospective study, we analyzed 124 patients with recurrent or metastatic non-nasopharyngeal HNC who received nivolumab in the second-line setting and beyond. Data were collected from 20 different cancer centers across Turkey. The effectiveness and safety of the treatment and survival outcomes were evaluated. RESULTS: Nivolumab exhibited favorable clinical responses, yielding an objective response rate of 29.9% and a disease control rate of 55.7%. Safety assessments revealed a generally well-tolerated profile, with no instances of treatment discontinuation or mortality due to side effects. Survival analysis disclosed a median overall survival (OS) of 11.8 (95% CI 8.4-15.2) months. Multivariate analysis revealed that ECOG-PS ≥ 1 (HR: 1.64, p = 0.045), laryngeal location (HR: 0.531, p = 0.024), and neutrophil-to-lymphocyte ratio > 3.5 (HR: 1.97, p = 0.007) were independent predictors of OS. CONCLUSIONS: Nivolumab is an effective and safe treatment option for patients with recurrent or metastatic non-nasopharyngeal HNC in real-world settings. Further studies are needed on factors affecting response to treatment and survival outcomes.
RESUMO
OBJECTIVE: This study investigates the prognostic significance of Hemoglobin, Albumin, Lymphocyte, Platelet (HALP) score and Prognostic Nutritional Index (PNI) in metastatic head and neck cancers. METHODS: Retrospective analysis was conducted on data obtained from January 2014 to June 2022 for 68 patients using rigorous statistical methods. HALP and PNI scores, derived from routine laboratory parameters, were categorized into low and high groups using respective median values. Prognostic significance was determined through Kaplan-Meier survival analyses and Cox proportional hazards regression using IBM SPSS Statistics. RESULTS: Of the 68 patients (80.9% male, median age 57), 39 (57.4%) had laryngeal cancer. When stratified by low and high HALP scores, the median overall survival (OS) was 5.9 and 16.4 months, respectively (P < 0.001), while the median progression-free survival (PFS) was 5.7 months and 8.2 months, respectively (P: 0.016). In the low and high PNI score groups, the median OS was 7 and 13.2 months (P < 0.001), with median PFS of 5.6 months and 8.2 months (P: 0.002), respectively. In the multivariate analysis, while the HALP score did not reach statistical significance in terms of PFS, the PNI score and age groups were found to be statistically significant. In terms of OS, higher HALP score and PNI scores were significantly associated with longer OS. CONCLUSION: In this study, the HALP score and PNI score were found to be a prognostic factor in patients with metastatic head and neck cancer.
RESUMO
In this article, we present a case of diffuse follicular variant papillary thyroid carcinoma with pituitary metastasis, which is a rare cause of pituitary metastasis. The follicular variant of papillary thyroid carcinoma is an uncommon variant of papillary carcinoma. A 74-year-old male was presented with weakness, fatigue, and a decreased appetite. The patient was diagnosed with secondary adrenal and thyroid insufficiencies. Imaging revealed a pituitary mass with suprasellar extension, right cavernous sinus invasion, and optic chiasm compression. Thyroid ultrasonography revealed a nodule with a maximum size of 7.2cm in the right lobe. Cytological examination via fine-needle aspiration suggested papillary thyroid cancer. Total thyroidectomy with central and right lateral neck dissection confirmed the diagnosis of diffuse follicular variant of papillary thyroid carcinoma. Owing to visual field defects, the patient underwent transsphenoidal surgery. Histological and immunohistochemical evaluations confirmed pituitary metastasis from the papillary thyroid cancer. Radioactive iodine treatment and gamma knife radiotherapy of the pituitary gland were performed. The initiation of sorafenib treatment was deemed appropriate during the follow-up. A significant decrease in the thyroglobulin levels was observed after sorafenib treatment. Pituitary metastasis should be considered in patients diagnosed with hypopituitarism and pituitary lesions at initial evaluation. The presence of visual field defects may be an indication for neurosurgical intervention and guide both diagnosis and treatment. The management of papillary thyroid cancer and the role of treatment modalities in prognosis depend on the biological behavior of the tumor. Early diagnosis and multidisciplinary management are crucial for the treatment of these patients.

BACKGROUND: In recent years, many studies have proven that percutaneous thermal ablation is an effective second-line treatment method with low complication rates in early-stage non-small cell lung carcinoma and lung metastases. Radiofrequency ablation and microwave ablation are commonly used for this purpose. PURPOSE: To evaluate the factors affecting the success of the percutaneous thermal ablation treatment with technical success, complication rates, and long-term follow-up results in metastatic lung lesions. MATERIAL AND METHODS: Computed tomography (CT)-guided percutaneous ablation was performed for 70 metastatic lung lesions in 35 patients (22 men, 13 women; mean age = 61.34 years; age range = 41-75 years). Radiofrequency ablation was performed in 53/70 (75.7%) lesions and microwave ablation in 17/70 (24.3%) lesions. RESULTS: The technical success rate was 98.6%. Median overall survival, progression-free survival, and local recurrence-free survival of the patients were 33.9 months (range=25.6-42.1 months), 12 months (range=4.9-19.2 months), and 24.2 months (range=8.2-40.1 months), respectively. One- and two-year overall survival rates were 84% and 74%, respectively. Median progression-free survival times were 20.3 months and 11.4 months, respectively, according to the number of metastatic lung lesions being single and multiple, and the difference was statistically significant (P = 0.046). According to the number of lesions ≤3 and >3, the difference was also found statistically significant (P = 0.024) (14.3 months and 5.7 months, respectively). CONCLUSION: In conclusion, CT-guided percutaneous thermal ablation is a safe and effective treatment method in metastatic lung lesions. The number of lesions is the most important factor in predicting treatment success.

OBJECTIVE: To examine the treatment outcomes of the EXTREME regimen as the first-line therapy for recurrent/metastatic squamous cell carcinoma of the head and neck. STUDY DESIGN: Observational study. Place and Duration of the Study: Department of Medical Oncology, Ankara Diskapi Yildirim Beyazit Training and Research Hospital, Turkiye, between January 2014 and December 2021. METHODOLOGY: A total of 60 patients with recurrent/metastatic head and neck cancers were treated with EXTREME regimen. Survival curves were estimated using the Kaplan-Meier method. Cox proportional hazards regression models were used to determine the factors associated with progression-free survival (PFS) and overall survival (OS). RESULTS: Patients receiving cetuximab in combination with chemotherapy for metastatic or unresectable disease were obtained from patient files and electronic medical records. Majority of patients were male (78.3%). The median PFS of patients was 7 months. The median survival of the patients was 9.06 months. During follow-up, 55 patients (91.7%) relapsed, and 51 patients (85%) died. The median survival of patients with eastern cooperative oncology group (ECOG) performance status 0, 1, and 2 was 16, 9, and 4 months, respectively. And the survival of patients was found significantly lower with lower ECOG performance scores. CONCLUSION: OS was determined as 9.06 months. ECOG performance score had an important effect on the survival. KEY WORDS: Cetuximab, Head and neck cancer, Chemotherapy.

Distant metastasis of laryngeal carcinoma occurs at the rate of 4%-12%, with the most common sites being the lungs, liver and bone. Acrometastasis occurs rarely in cases of laryngeal carcinoma; to date, only three cases of acrometastasis have been reported. Herein, we describe a 66-year male, who was followed up for metastatic laryngeal carcinoma and developed paronychia. Hot compress was applied, antibiotic treatment was administered, and fine-needle biopsy of the lesion was performed. The lesion did not regress despite the administration of a broad-spectrum antibiotic. The results of cytological examinations were consistent with squamous cell carcinoma metastasis. Rarely occurring acrometastases indicate poor prognosis in cancer patients; expected survival is short and treatment is usually palliative. In such cases, finger amputation or local radiotherapy are recommended. Clinicians should be aware when treating metastatic laryngeal cancer that such atypical lesions as paronychia can be associated with the primary tumour. Key Words: Acrometastasis, Laryngeal carcinoma, Finger, Metastasis.

Introduction Colonic wall thickening (CWT) is frequently observed incidentally via abdominal computerized tomography (aCT). Although the general approach to evaluating incidental CWT is a colonoscopic examination, there is a lack of definitive recommendation guidelines. Thus, we aimed to determine neoplasia rates and identify the factors predictive of neoplasia via colonoscopic examinations of patients with CWT incidentally diagnosed via aCT. Methods We retrospectively reviewed 5,300 colonoscopy reports. A total of 122 patients who had CWT incidentally observed via aCT were included in the study. CWT was graded as mild (3-5 mm), moderate (6-12 mm), or severe (≥12 mm). A logistic regression model was used to determine the predictive factors for neoplasia. Results The mean age of the patients was 60 years, and abnormal findings were noted in 52% of the colonoscopies. Neoplastic lesions were detected in 24 patients (19.6%), while colon adenocarcinoma was detected in 8 patients (6.5%). Multivariate analysis showed that moderate-severe, focal, and asymmetric CWT were independent factors for predicting neoplasia (p=0.049, p=0.033, and p=0.018, respectively). Conclusion Pathological findings can be noted via colonoscopic examination in cases of incidental CWT; therefore, patients with moderate-severe, focal, or asymmetric CWT require colonoscopic examination for the purpose of detecting neoplasia.
RESUMO
Lorlatinib is a third-generation tyrosine-kinases inhibitor (TKI) targeting ALK/ROS1 fusions. The FDA has approved lorlatinib for TKI-pretreated ALK(+) NSCLC, while its approval for ROS1(+) is still pending. Here we present the largest real-world data of NSCLC patients harboring ALK/ROS1 rearrangements treated with lorlatinib. METHODS: 123 patients were enrolled retrospectively (data cut-off 1/1/2019). Lorlatinib was administered through an early access program for patients with no other available therapy. Outcome and response were defined by each investigator upon RECIST 1.1 criteria. RESULTS: 106 ALK(+) and 17 ROS1(+) patients recruited from 8 different countries. The ALK(+) cohort included 50 % males, 73 % never-smokers and 68 % with brain metastases. Extracranial (EC) and intracranial (IC) response rates (RR) were 60 % and 62 %, with disease control rates (DCR) of 91 % and 88 % respectively. Mean duration of therapy (DoT) was 23.9⯱â¯1.6 months and median overall survival (mOS) was 89.1⯱â¯19.6 months. ROS1 cohort enrolled 53 % males, 65 % never-smokers and 65 % had brain metastases. EC and IC RR were 62 % and 67 % with DCR of 92 % and 78 % respectively. Median DoT was 18.1⯱â¯2.5 months and mOS of 90.3⯱â¯24.4 months. OS and DoT in both cohorts were not significantly correlated with line of therapy nor other parameters. The most common adverse events of any grade were peripheral edema (48 %), hyperlipidemia (47 %), weight gain (25 %) and fatigue (30 %). CNS adverse events such as cognitive effect of grade 1-2 were reported in 18 % of patients. CONCLUSION: Lorlatinib shows outstanding EC/IC efficacy in ALK/ROS1(+) NSCLC. The observed mOS of 89⯱â¯19 months in ALK(+) NSCLC supports previous reports, while mOS from of 90⯱â¯24 months is unprecedented for ROS1(+) NSCLC.

PURPOSE: To analyze the reliability and the effectiveness of chemotherapy and prognostic factors for survival in patients with HER2 (human epidermal growth receptor 2) negative early-stage breast cancer treated with adjuvant sequential anthracycline-based chemotherapy and paclitaxel. METHODS: This analysis retrospectively evaluated the medical records of 756 HER2 negative early-stage breast cancer patients who received adjuvant sequential anthracycline-based chemotherapy and weekly paclitaxel in 15 medical oncology centers in Turkey between 2008-2015. Estrogen receptor (ER), progesterone receptor (PR),HER2,age,tumor size and grade,nodal status,perineural and lymphatic invasion,disease-free survival (DFS) and overall survival (OS) were analyzed. RESULTS: The median patient age was 50 years (22-82). Median follow up period was 46 months (13-82). The rates of recurrence and death detected in this period were 14.8% and 7.4%, respectively. Median OS and PFS were not reached in this period. Five-year DFS and OS rates were 87% and 89%, respectively. Age (OR:0.35,95%Cl 0.12-0.96, p=0.04), PR status (OR:0.44,95%Cl 0.18-1, p=0.05), lymphatic invasion (OR:2.6,95%Cl 0.97-7.4, p=0.05) were independent prognostic factors. Most common grade 3-4 toxicities were fatigue (6.7%), neutropenia (1.7%) and nausea (1.3%). Neutropenic fever developed in 1.8% of the patients and peripheral neuropathy in 16.9%. Dose reduction was necessary for 10% of the patients due to grade 3-4 toxicity, whereas postponement of chemotherapy was necessary for 7% of the patients. CONCLUSIONS: This multicentric retrospective study confirmed that sequential adjuvant therapy with anthracycline-based chemotherapy and paclitaxel for HER2 negative breast cancer is an effective and reliable regimen.

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: Small bowel adenocarcinoma (SBA) is a rare tumor of the gastrointestinal system with poor prognosis. Because these are rarely encountered tumors, the aim of this multicenter study was evaluation of prognostic factors and adjuvant chemotherapy in patients with curatively resected SBA. MATERIALS AND METHODS: A total of 78 patients diagnosed with curatively resected SBA were involved in the retrospective study. Forty-eight patients received 1 of 3 different chemotherapy regimens, whereas 30 patients did not receive any adjuvant treatment. No adjuvant and adjuvant chemotherapy cohorts were matched (1:1) by propensity scores based on the likelihood of receiving chemotherapy or the survival hazard from Cox modeling. Overall survival (OS) was compared with Kaplan-Meier estimates. RESULTS: Median age of 78 patients with curatively resected SBA was 58, and 59% of these were men. According to TNM classification, 8 (10%) of the patients were at stage I, 26 (34%) were at stage II, and 44 (56%) were at stage III. Median follow-up duration was 29 months. Three-year median disease-free survival (DFS) and OS were 62.5% and 67.0%, respectively. In univariate analysis, presence of vascular invasion, perineural invasion, lymph node involvement, and presence of positive surgical margin were significant predictors of poor survival. Multivariate analysis showed that the only adverse prognostic factor independently related with OS was the presence of positive surgical margin (hazard ratio, 0.37; 95% confidence interval, 0.11-1.26; P = .01). Neither DFS nor OS was found to be significantly improved by the adjuvant chemotherapy in both matched and unmatched cohorts. CONCLUSIONS: Only status of surgical margin was determined to be an independent prognostic factor in patients with SBA who underwent curative resection.

PURPOSE: The aim of the study was to investigate the association between the molecular subtypes and patterns of relapse in breast cancer patients who had undergone curative surgery. METHODS: We retrospectively evaluated 1,350 breast cancer patients with relapses after curative surgery between 1998 and 2012 from referral centers in Turkey. Patients were divided into 4 biological subtypes according to immunohistochemistry and grade: triple negative, HER2 overexpressing, luminal A and luminal B. RESULTS: The percentages of patients with luminal A, luminal B, HER2-overexpressing, and triple-negative breast cancer were 32.9% (n = 444), 34.9% (n = 471), 12.0% (n = 162), and 20.2% (n = 273), respectively. The distribution of metastases differed among the subgroups: bone (66.2% and 53.9% in luminal A and B vs. 38.9% in HER2-overexpressing and 45.1% in triple negative, p < 0.001), liver (40.1% in HER2-overexpressing vs. 24.5% in luminal A, 33.5% in luminal B, and 27.5% in triple negative, p < 0.001), lung (41.4% in triple negative and 35.2% in HER2-overexpressing vs. 30.2% and 30.6% in luminal A and B, p = 0.008) and brain (25.3% in HER2-overexpressing and 23.1% in triple negative vs. 10.1% and 15.1% in luminal A and B, p < 0.001). CONCLUSIONS: Organ-specific metastasis may depend on the molecular subtype of breast cancer. Tailored strategies against distant metastasis concerning the molecular subtypes in breast cancer should be considered.
RESUMO
PURPOSE: Medulloblastoma (MB) is rarely seen in adults. For adjuvant therapy in adults the same therapy protocols used in pediatric cases are used. The present study retrospectively evaluated the data of MB patients who were treated in different Oncology Centers in Turkey. METHODS: The data of 60 adult patients with MB from 8 Oncology Centers diagnosed between 2005 and 2012 were retrospectively analyzed. RESULTS: The median patient age was 28.8 years (range 16-54). The administered chemotherapy included procarbazine+lomustin+vincristine (group A, N=31) and cyclophosphamide/ifosfamide+vincristine+cisplatin (group B, N=13). Median chemotherapy courses were 4 (range 1-8). Median progression free survival (PFS) was 76 months and median overall survival (OS) has not been reached in both groups. In young female patients and in those who received adjuvant chemotherapy, median PFS and OS were longer but without statistical significance. Mean PFS and OS were 65.9 months and 101.2 months in group A and 113.6 months and 141.6 months in group B, respectively. CONCLUSION: Improved survival results were obtained in women, in patients aged below 25 years, in those who underwent gross total excision (GTE) and in those who received adjuvant therapy with cyclophosphamide/ifosphamide.

PURPOSE: The aim of this study was to determine risk factors for brain metastasis as the first site of disease recurrence in patients with HER2-positive early-stage breast cancer (EBC) who received adjuvant trastuzumab. METHODS: Medical records of 588 female patients who received 52-week adjuvant trastuzumab from 14 centers were evaluated. Cumulative incidence functions for brain metastasis as the first site of disease recurrence and the effect of covariates on brain metastasis were evaluated in a competing risk analysis and competing risks regression, respectively. RESULTS: Median follow-up time was 36 months. Cumulative incidence of brain metastasis at 12 months and 24 months was 0.6% and 2%, respectively. HER2-enriched subtype (ER- and PR-) tumor (p = 0.001, RR: 3.4, 95% CI: 1.33-8.71) and stage 3 disease (p = 0.0032, RR: 9.39, 95% CI: 1.33-8.71) were significant risk factors for development of brain metastasis as the first site of recurrence. CONCLUSIONS: In patients with HER2 positive EBC who received adjuvant trastuzumab, HER2-enriched subtype (ER- and PR-) tumor and stage 3 disease were associated with increased risk of brain metastasis as the first site of disease recurrence.

BACKGROUND: The relapses of colorectal cancer (CRC) frequently occur in 2 years period after the time of diagnosis. However, a considerable proportion of patients relapse in the late period. AIM: The aim of the present study is to define the factors predicting the early and late relapses of patients with early stage CRC. MATERIALS AND METHODS: A total of 250 patients with CRC, who relapsed after completion of primary therapy between 2005 and 2014, were enrolled in the study. According to the time of relapse, patients were divided into two groups as follows: Early relapse (Group 1: Within first 24 months) and late relapse (Group 2: Later than 24 months). Clinicopathological features and survival rates of the two groups were compared. RESULTS: Of 250 patients, 151 (60.4%) (Group 1) were relapsed within the first 24 months after completion of the primary therapy and 105 (39.6%) were relapsed later than 24 months. The patients with T1-T2 and Grade I tumors were relapsed in late period (P < 0.05). The rates of administered systemic chemotherapy and targeted therapies after relapse were similar in both groups. The median overall survival rates in patients relapsed within the first 24 months and after 24 months were 18 months and 21 months, respectively (P = 0.05). CONCLUSIONS: In patients with CRC, the time duration of relapse after completion of the operation and adjuvant chemotherapy was a prognostic factor. Grade I and superficial tumors (T1-T2) are the predictors of late relapses (after >24 months). The patients relapsed within the first 24 months after primary therapy had poor prognosis compared to those who relapsed in late period.

Most data on prognostic factors for patients with high-grade undifferentiated pleomorphic sarcoma (HGUPS) is obtained from analyses of soft tissue sarcomas. The purpose of this study was to evaluate the clinicopathologic features and their impact on outcomes specifically in patients diagnosed with HGUPS. In this multicenter trial, we retrospectively analyzed 112 patients who were diagnosed and treated at 12 different institutions in Turkey. We collected data concerning the patients, tumor characteristics, and treatment modalities. There were 69 males (61.6 %) and 43 females (38.4 %). Median age was 56 years (19-90). The most common anatomic site of tumor origin was the upper extremity. Pleomorphic variant was the predominant histological subtype. Median tumor size was 8.2 cm (0.6-30 cm). Tumors were mainly deeply seated (57.1 %). Fifty-seven patients (50.9 %) were stage II and the remainder were stage III at the time of diagnosis. Median follow-up was 30 months (2-160). The primary site of distant metastasis was the lung (73.5 %) and the second most common site was the liver (11.7 %). The 5-year overall survival, distant metastasis-free survival, and local recurrence-free survival rates were 56.3, 53.4, and 67.2 %, respectively. Multivariate analysis showed that Eastern Cooperative Oncology Group (ECOG) performance score of II (p = 0.033), deep tumor location (p = 0.000), and development of distant metastasis (p = 0.004) were negatively correlated with overall survival, and perioperative radiotherapy and negative microscopic margins were significant factors for local control rates (p = 0.000 for each). Deep tumor location (p = 0.003) was the only adverse factor related to distant metastasis-free survival. Deep tumor location, ECOG performance score of II, and development of distant metastasis carry a poor prognostic implication on overall survival. These will aid clinicians in predicting survival and treatment decision.

Coexistence of two or more primary cancers is a relatively rare case. Not with standing that the coexistence of multiple primary cancers is often discussed in the literature, there is a small number of publications concerning the coexistence of squamous cell lung carcinoma and renal cancer. In this case report, detection of both squamous cell lung carcinoma and primary renal cancer in one male patient is going to be discussed.
RESUMO
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.
