A case of radiation-induced sternal malignant fibrous histiocytoma treated with neoadjuvant chemotherapy and surgical resection

<p>Abstract</p> <p>Background</p> <p>Primary sternal malignant fibrous histiyocytoma (MFH) is highly rare. Effective treatment modality is surgical resection with wide margins. However, to date, the effects of radiotherapy or chemotherapy has not been clearly defined.</p> <p>Case presentation</p> <p>Herein, we aimed to present a 50-year old female patient with MFH occurred in the radiotherapy field who had had surgical procedure for breast cancer 19 years ago and had followed by radiotherapy. Neoadjuvant chemotherapy was applied for MFH due to cardiac and mediastinal vascular invasion. Wide resection was carried out for the mass after having been decreased in size following neoadjuvant chemotherapy.</p> <p>Conclusion</p> <p>Neoadjuvant chemotherapy was an effective method. In planning the surgical resection, the size of the tumor before chemotherapy should be considered as the initial size and surgical margins should be determined accordingly.</p

Efficacy and Safety of Erlotinib in Previously Treated Advanced Non-Small Cell Lung Cancer

Erlotinib is a potent inhibitor of the epidermal growth factor receptor (EGFR) tyrosine kinase, with single-agent antitumor activity which improves symptom control and quality of life compared with placebo in non-small-cell-lung cancer (NSCLC) patients. We aimed to determine the efficacy and safety of the second, third or fourth-line erlotinib in advanced NSCLC patients in Turkish population. Eighty patients (33 males and 47 females) were retrospectively evaluated. All patients had received a platinum-based regimen as the first-line metastatic therapy. Most of the patients (62.5%) had received erlotinib as the second-line treatment. None of the patients had EGFR mutation studied. One patient achieved a complete response, 10 patients partial response and 21 stable diseases. The overall response rate was 14% and disease control rate was 40%. The median progression-free survival (PFS) and overall survival (OS) were 12 months and 18 months, respectively. Although, there was no survival difference between male and female patients, the median PFS of females was significantly better than male patients (p=0.03). There was no significant difference in disease control rate in terms of age, smoking status, erlotinib line, performance status (PS), stage and skin rash. The most common adverse events were skin rash (56%), diarrhea (9%) and anorexia (8%). Sixteen patients (20%) developed grade 3 toxicities. Grade 4 toxicity or treatment related interstitial lung disease were not observed. Erlotinib showed an acceptable response rate, survival time and toxicity after disease progression with chemotherapy. It's an alternative therapy as a second or third-line therapy in patients with NSCLC. Prospective studies are needed to evaluate the efficiency of the treatment in Turkish population

Outcome of 561 non-metastatic triple negative breast cancer patients: Multi-center experience from Turkey

Purpose: Triple-negative breast cancers account for 15% of breast carcinomas and, when present as early-stage disease, they are associated with higher rates of recurrence and early distant metastasis risk when compared to hormone receptor positive and human epidermal growth factor receptor (HER-2) positive breast cancers. In this study we aimed to explore the basic clinicopathological characteristics, prognostic factors and recurrence patterns of non-metastatic triple negative breast cancer patients

The efficacy and toxicity of irinotecan with leucovorin and bolus and continuous infusional 5-fluorouracil (FOLFIRI) as salvage therapy for patients with advanced gastric cancer previously treated with platinum and taxane-based chemotherapy regimens

There is no established standard salvage chemotherapy in the second-line setting for patients with advanced gastric cancer (AGC) pre-treated with platinum and taxane-based chemotherapy. Our study aims to evaluate the safety and efficacy of FOLFIRI regimen (irinotecan with leucovorin and bolus and continuous infusion with 5-fluorouracil) as a salvage chemotherapy regimen in patients with AGC. Medical records of 97 patients with AGC who received second-line FOLFIRI regimen between March 2006 and February 2011 were examined. Complete and partial responses were observed in 3 (3.1%) and 23 (23.7%) patients, respectively. The median time to progression (TTP) was 3.5 months (95% CI: 2.4-4.6) and the median overall survival (OS) was 10.5 months (95% CI: 8.8-12.2). The most common observed grade 3/4 toxicities were neutropenia (23.7%), diarrhea (6.2%), and stomatitis (5.2%). FOLFIRI regimen is safe and effective in the second-line treatment of AGC patients pre-treated with cisplatin and taxanes

Assessment of tumor characteristics and factors affecting survival in patients with primary metastatic breast carcinoma: a Multicenter Study of the Anatolian Society of Medical Oncology

Primary metastatic breast cancer (PMBC) comprises 3-10 % of all BCs. PMBC is a heterogeneous disease. To date, little is known about the tumor characteristics, treatment results, and overall survival ( OS) of patients with PMBC. Patients were considered to have PMBC if distant metastasis was evident within 3 months of the initial diagnosis of BC. Between September 2007 and April 2013, 466 PMBC patients were included in this study and analyzed retrospectively. The median age of the patients was 50 (18- 90) years. Bone/ soft tissue metastases were more frequent in the hormone receptor (HR)(+) human epidermal growth factor receptor ( HER) 2(-) group compared with the HR(-) HER2(-) and HR(-) HER2(-) groups ( p < 0.001), whereas visceral organ metastasis was more frequent in the HR(-) HER2(-) and HR(-) HER2(-) groups ( p < 0.001). The OS was affected by Eastern Cooperative Oncology Group performance status, tumor histology, receptor status, and the site of metastasis ( p < 0.001, p < 0.001, p < 0.001, and p = 0.011, respectively). According to the first-line systemic treatment choices of the patients, the longest median OS was observed in the HR(?) HER2(-) group who received hormonotherapy combined with trastuzumab after chemotherapy ( 86 months, 95 % CI 23.8-148.1) and the shortest median OS was observed in the HR(-) HER2(-) group who received chemotherapy only ( 24 months, 95 % CI 17.9-30.0) ( p < 0.001). Bisphosphonate therapy or radiotherapy had no significant effect on OS ( p = 0.733, 0.603). In multivariate analysis, hormonotherapy, chemotherapy + trastuzumab, trastuzumab + hormonotherapy following chemotherapy, and surgery were the most important prognostic factors for OS, respectively ( p < 0.001, p = 0.025, p = 0.027, p = 0.029). The general characteristics of the primary tumor are important for the prognosis and survival of patients with PMBC. Interestingly, patients who underwent primary breast tumor surgery, even those at the metastatic stage upon admission, had the longest survival
