Prognostic Impact of Neutrophil/Lymphocyte Ratio, Platelet Count, CRP, and Albumin Levels in Metastatic Colorectal Cancer Patients Treated with FOLFIRI-Bevacizumab.

PURPOSE: Metastatic colorectal cancer (mCRC) is a lethal disease and fluorouracil-leucovorin-irinotecan (FOLFIRI) plus bevacizumab (bev) is a standard approach. Hence, there is a strong need for identifying new prognostic factors to show the efficacy of FOLFIRI-bev. METHODS: This is a retrospective study including patients (n = 90) with mCRC from two centers in Turkey. Neutrophil/lymphocyte (N/L) ratio, platelet count, albumin, and C-reactive protein (CRP) were recorded before FOLFIRI-bev therapy. The efficacy of these factors on progression-free survival (PFS) was analyzed with Kaplan Meier and Cox regression analysis. And the cutoff value of N/L ratio was analyzed with ROC analysis. RESULTS: The median age was 56 years (range 21-80). Forty-seven percent of patients with N/L ratio >2.5 showed progressive disease versus 43 % in patients with N/L ratio <2.5 (p = 0.025). The median PFS was 8.1 months for the patients with N/L ratio >2.5 versus 13.5 months for the patients with N/L ratio <2.5 (p = 0.025). At univariate Cox regression analysis, high baseline neutrophil count, LDH, N/L ratio, and CRP were all significantly associated with poor prognosis. At multivariate Cox regression analysis, CRP was confirmed to be a better independent prognostic factor. CRP variable was divided into above the upper limit of normal (ULN) and normal value. The median PFSs of the patients with normal and above ULN were 11.3 versus 5.8 months, respectively (p = 0.022). CONCLUSIONS: CRP and N/L ratio are potential predictors for advanced mCRC treated with FOLFIRI-bev.

Trastuzumab-based Retreatment after Lapatinib in Heavily Pretreated HER2 Positive Metastatic Breast Cancer: an Anatolian Society of Medical Oncology Study.

BACKGROUND: For HER2 positive metastatic breast cancer (MBC), continuing anti-HER2 therapy beyond progression is associated with improved outcome. However retreatment with trastuzumab after lapatinib progression is controversial. We retrospectively analyzed the efficacy of trastuzumab-based chemotherapy in HER2+ metastatic breast cancer patients whose disease progressed after lapatinib. MATERIALS AND METHODS: Between October 2010 and May 2013, 54 patients whose disease progressed after lapatinib were retreated with trastuzumab-based chemotherapy. Efficacy and toxicity results were evaluated retrospectively. RESULTS: The median age of patients was 46 (range 27-67). Fourteen patients (26%) had metastases at the time of diagnosis. All of the patients had received trastuzumab in an adjuvant or metastatic setting, while 16 (30%) had received two lines of trastuzumab. All patients had received lapatinib plus capecitabine. The median chemotherapy line for the metastatic setting was 2 (range 1-7). Cranial metastases were identified in 27 (50%) patients. 53 patients received trastuzumab-based chemotherapy following lapatinib progression while one patient received trastuzumab monotherapy. Combination chemotherapy consisted of navelbin (n=33), taxane (n=10), gemcitabine (n=2), platinum (n=2) and platinum with taxane (n=6). The median treatment cycle was 5 (range 1-44). Among 49 patients assessed for response 2 (4%) showed CR, 12 (25%) PR, 11 (22%) SD and 24 (49%) disease progression. Asymptomatic cardiotoxicity was reported in 2 (4%) of the patients. At a median follow-up of 9 months (1-39), median progression-free survival was 5 months (95% CI 4.1-5.9) and median overall survival was 10 months (95% CI 6.9-13.0). PFS and OS were not affected by the absence/presence of cranial metastases. CONCLUSIONS: Retreatment with trastuzumab-based therapy after lapatinib progression showed efficacy in heavily treated MBC patients.

Prognostic value of ERCC1, ERCC2, XRCC1, and TP53 single nucleotide polymorphisms in patients with early-stage non-small cell lung cancer.

Identification of biomarkers used for the prognostic evaluation of non-small cell lung cancer (NSCLC) patients is important. The aim of this study was to evaluate the potential prognostic value of XRCC1, ERCC1, ERCC2, and TP53 single nucleotide polymorphisms (SNPs) in completely resected NSCLC patients. In total, 130 patients, surgically treated for NSCLC between 2000 and 2012, were included. An analysis of SNPs from peripheral blood cells was performed by polymerase chain reaction. XRCC1 Arg399Gln, ERCC1 Asn118Asn, ERCC2 Lys751Gln, and TP53 Arg72Pro polymorphisms were evaluated in conjunction with clinical and pathological parameters and survival. Kaplan-Meier method and Cox regression analysis were used. Median age rate was 59.3, ranging between 36 and 78 years. Median relapse-free survival duration (RFS) was found as 46.2 months. In those with ERCC2 CC allele, median RFS was detected as 28.3 months (95 % confidence interval (CI), 20.8-35.8), 46.9 months in those with CT heterozygous (95 % CI, 18.6-75.2), and 80.1 months for those with TT mutant allel (95 % CI, 33.0-127.2). Median RFS was seen to be longer in mutant group and also statistically significant (P = 0.018). Additionally, upon evaluating CC normal group with CT + TT alleles including mutant alleles, median RFS was found as 56.5 months (95 % CI, 24.6-88.4) in CT + TT group, and this was statistically significant (P = 0.005) Also, median RFS was 15.1 months in those including ERCC2 CC allele and 56.5 months in CT + TT allele in the group with no adjuvant treatment (P = 0.001). In conclusion, our study showed that ERCC2/XPD polymorphism is an independent prognostic factor in operated NSCLC patients, and these findings should be supported with prospective studies.

Clinicopathologic features and molecular subtypes of breast cancer in young women (age ≤35).

INTRODUCTION: Breast cancer in young women is a relatively rare disease; however it tends to be more aggressive and is the leading cause of cancer death in this population. The aim of this study is to investigate the clinical and biological features of breast cancer arising in young Turkish breast cancer patients. MATERIALS AND METHODS: Patients with breast cancer aged 35 or less (≤35 years) were selected for the study. In total 211 cases were included. Pathologic features; histologic subtypes, grade, lymphovascular invasion, axillary involvement, and stage were recorded for each. RESULTS: The most common subtype was luminal B (36.5%), followed by luminal A (30.8%), triple negative (23.2%) and HER2+(9.5%) subtypes. Twelve percent of the patients had stage 4, 32.7% had stage 3, 46.4% had stage 2, and 6.2% had stage 1 disease at the time of diagnosis. Mean tumour diameter was 3.87 cm (range 0.3-13 cm). The axillary lymph nodes were positive in 74.4% of the patients, while lympho-vascular invasion was seen in 56.4%. Some 9.5% of patients had grade 1, 51.2% had grade 2, and 31.8% had grade 3 tumors. CONCLUSIONS: Young women with breast cancer in Turkey are more likely to present with luminal B subtype. Tumors in young women are more likely to present with advanced disease, to be high grade and and to have more lymphovascular invasion. Further research should focus on whether we need new treatment strategies for young patients with breast carcinoma.

Complete response and long-term remission to anti-HER2 combined therapy in a patient with breast cancer presented with bone marrow metastases.

Presentation with bone marrow metastasis at diagnosis is a rare event in breast carcinoma. Here, we report a rare presentation of metastatic breast cancer patient with bone marrow metastases, who was successfully treated with trastuzumab combined chemotherapy. The regimens initially applied for bone marrow metastasis were docetaxel/adriamycin, gemcitabine/vinorelbine, epirubicin/cyclophosphamide, capecitabine, docetaxel, gemcitabine, and paclitaxel. But, the best response to these regimens was not satisfactory. Our patient was completely treated with etoposide-cisplatin and trastuzumab combination. She is still on remission after five years of metastatic breast cancer diagnosis using letrozole and trastuzumab without complication. Physicians should be careful in treating bone marrow metastases in breast cancer, since patients can show improved marrow function after chemotherapy and long-lasting survival is possible.

Childhood, adolescents, and young adults (≤25 y) colorectal cancer: study of Anatolian Society of Medical Oncology.

PURPOSE: To evaluate the clinicopathologic characteristics and treatment outcomes of young patients with colorectal cancer (CRC). METHODS: Between May 2003 and June 2010, 76 patients were found eligible for this retrospective study. Age, sex, presenting symptoms, patients with acute presentation, family history, presence of polyps, histologic features, localization and stage of the tumor, treatment outcomes, time and site of recurrence, sites of metastasis, and survival outcomes were recorded from the patient files. RESULTS: Seventy-six patients (55.3% male) with a median age of 23 years were evaluated. Patients were evaluated in 2 groups as follows: child-adolescent (0 to 19 y, n=20) and young adult (20 to 25 y, n=56). Sex and symptoms (abdominal pain and rectal bleeding) were significantly differed between the groups and acute presentation was close to statistical significance. Overall survival significantly increased in patients undergoing curative surgery (P<0.001). Other parameters affecting the survival was stage of disease (P=0.004). Response to palliative chemotherapy in metastatic patients (P=0.042) and postoperative adjuvant chemotherapy had a statistically significant survival advantage (P=0.028). CONCLUSIONS: Diagnosis of CRC should not be excluded solely on the basis of age. CRC features in young-adult patients are more similar to adults compared with that of child-adolescent patients according to the symptoms and presentation. In patients with CRC in this age group, curative surgery, adjuvant chemotherapy, and palliative chemotherapy provide survival advantage.

The efficacy and safety of reduced-dose docetaxel, cisplatin, and 5-fluorouracil in the first-line treatment of advanced stage gastric adenocarcinoma.

Patients with advanced gastric carcinoma have still had bad prognosis despite advances in the modern treatment era. Docetaxel, cisplatin, 5-fluorouracil (DCF) is effective, but highly toxic regimen for advanced cases. In this study, we modified the standard doses of DCF (mDCF) to evaluate the effectiveness and side effects. From July 2005 to July 2008, 37 advanced gastric cancer patients treated with at least one course of mDCF protocol as first-line treatment were included. The mDCF protocol included 60 mg/m(2) docetaxel and cisplatin for 1 day and 600 mg/m(2)/day, 5-flourouracil infusion for 5 days, repeated every 3 weeks. No patients used prophylactic granulocte -colony stimulating factor. Of the patients, 28 were male and nine were female; the median age was 53 (23-65) years. Of them, 83.8% received at least four courses of chemotherapy and 64.9% completed the preplanned six courses of treatment. Eleven (29.7%) of those patients who received mDCF in the first-line treatment used the FOLFIRI (5-FU, folinic acit, irinotekan) regimen for the second-line treatment. Response rates were evaluated according to RECIST criteria in 30 out of 37 patients. The median follow-up time was 7.1 months. The longest follow-up time was 19.9 months. Two patients (5.4%) had complete response, nine (21.6%) had partial response, and 14 (37.9%) had stabilized disease; overall, the disease was controlled in 25 patients (64.9%) whereas five patients (13.5%) had progression. Median time to progression was 6.7 months and overall survival was 10 months. The assessment of patients for grade 3-4 toxicity revealed that while 5.4% had anemia and 8.1% had neutropenia, 5.4% nausea and 5.4% diarrhea. Neutropenic fever developed in two patients, requiring hospitalization. G-CSF was used in three patients. Two patients with neutropenic fever and two with severe anemia (total number 4; 10.8%) received delayed chemotherapy. Dose reduction was required in four patients (10.8%), one due to neutropenia, one due to nephrotoxicity, and two due to nausea. No patient died due to chemotherapy toxicity. This retrospective study suggested that mDCF might have comparable efficacy with classical DFC, with better toxicity profile. However, its small size and retrospective nature should be considered when interpreting the results.

Comparison of ICE (ifosfamide-carboplatin-etoposide) versus DHAP (cytosine arabinoside-cisplatin-dexamethasone) as salvage chemotherapy in patients with relapsed or refractory lymphoma.

BACKGROUND: High dose chemotherapy with autologous stem cell transplantation is currently the treatment of choice for relapsed or refractory lymphoma patients. However, its applicability is mostly restricted to patients responding to salvage chemotherapy. Optimal salvage regimen for these patients is unclear. In this study, our aim was to compare the efficacy and toxicity profiles of DHAP (cytosine arabinoside, cisplatin and dexamethasone) and ICE (ifosfamide, carboplatin and etoposide) regimens in the salvage treatment of relapsed and refractory lymphoma. PATIENTS AND METHODS: In this retrospective analysis, 53 patients with primary refractory or relapsed Hodgkin's disease (HD) (n = 13) or non-Hodgkin lymphoma (NHL) (n = 40) who received ICE or DHAP salvage regimen were included. RESULTS: Of 53 patients, 21 (39,6%) were female and the median age was 43 years. A total of 73 courses of ICE and 59 courses of DHAP were administered. Response could be evaluated in 49 patients (36 NHL and 13 HD). Of 49 patients, 11 (22.5%) achieved complete remission (CR) and 17 (35%) achieved partial remission (PR), leading to an overall response rate (ORR: CR + PR) of 57.5%. In the evaluable ICE group (n = 22) rates of CR, PR, and ORR were 27%, 41% and 68% and in the DHAP group (n = 27) rates of CR, PR, and ORR were 18%, 30% and 48% (p = 0.24, for ORR). Toxicity with both regimens was within acceptable limits. The major grade III-IV toxicities for both groups were hematological (neutopenia and thrombocytopenia). The main non-hematological toxicity was renal and observed in 8 patients. CONCLUSION: Although the toxicity profiles of both ICE and DHAP regimens were similar in the treatment of patients with relapsed or refractory HD or NHL, ICE seems to have higher rates of response than DHAP regimen does.

Prognostic factors and clinicopathological characteristics of carcinoma of ampulla Vateri.

The aim of this study was to describe the clinicopathological characteristics and prognostic factors of carcinoma of ampulla Vateri. The medical records of 32 patients (24 men, 8 women) were evaluated. Median age was 59 years (range, 36-80 years). The performance status at the time of admission of (European Cooperative Oncology Group) 18 patients (56.3%) were ECOG-1; 8 patients (25.0%) were ECOG-2. Fifteen patients had early stage, 15 patients had locally advanced stage. Twenty-eight of 32 patients underwent curative surgery. Eleven, nine, and four patients had high-, moderate-, and low-grade histology, respectively. Fourteen patients received adjuvant treatment. Ten out of 14 patients were treated with chemotherapy. ECOG performance status (P = 0.06), stage (P = 0.05), perineural invasion (P = 0.01), tumor grade (P = 0.01), and treatment with chemotherapy, chemoradiotherapy, or only radiotherapy (P = 0.001) had a statistically significant impact on overall survival, whereas only tumor histopathology (P < 0.001) was shown to have a statistically significant effect on disease-free survival. Carcinoma of ampulla Vateri is a rare gastrointestinal tumor. Prospective trials with larger number of patients are needed to determine the prognostic factors to help select patients for adjuvant treatment.
