    ABSTRACT: Actinomycosis is a chronic suppurative infection, for which immune suppression is a predisposing factor. In unusual cases, this disease may present as an abdominal wall involvement simulating a soft tissue tumor as seen in the present case. The presented patient had no signs of trauma or surgical approach and the pathology was considered to be a primary abdominal wall actinomycosis. Preoperative diagnosis is difficult due to the nonspecific nature of clinical presentation, radiographic and laboratory findings. Surgery combined with antibiotic treatment is a curative approach for this relatively rare infection. Surgeons must be aware of this disease in order to ensure correct diagnosis and to prevent performing any unnecessary procedures. The present study describes a case of abdominal actinomycosis with multiple myeloma, together with a review of important points related to this disease.

    ABSTRACT: Özet Giriş: Osteosarkomlar patolog, radyolog, ortopedist, radyasyon onkoloğu ve medikal onkolog tarafından multidisipliner olarak yönetilmesi gereken bir hastalıktır. Biz bu çalışmada merkezimizdeki osteosarkom tanılı hastaların demografik özellikleri ve tedavi modalitelerini incelemeyi amaçladık. Gereç ve Yöntem: Cukurova Üniversitesi Tıp Fakültesi Tıbbi Onkoloji Bilim Dalı'nda 1999-2010 tarihlerinde osteosarkom tanısıyla tedavi almış ve takip edilmiş hastaların verileri retrospektif olarak araştırıldı. Bulgular: Osteosarkom ta-nılı 119 hastanın %74 ü erkek, %26 sı kadın hastadan oluşmaktaydı. Medi-an yaş 19, median takip süresi 37 ay dı. En sık görülen patolojik alt tip, % 82.4 osteoblastik osteosarkomdu. Hastalığın lokalizasyonu %55 alt extremi-te, %14.1 i üst extremite, %13 baş-boyun bölgesi, %6.6 torakal bölge, %4.1 pelvik bölge idi. Hastaların %6.41 lokal, %25.64 lokal-ileri, %15.8 metastatik evre ve %14.10 nüks hastalıktı. 119 hastanın 77 si kemoterapi aldı. Hastala-rın %23.1 i preoperatif, %16.67 si postoperatif, %9.52 si palyatif, %33.33 ü preoperatif+postoperatif, % 2.38 postoperatif+palliative, %9.52 si preopera tif+postoperatif+palliative kemoterapi ve %4.76 hast ise kemoterapi almadı. Cerrahi yaklaşımlar radikal ve konservatif olarak yapıldı. En sık metastaz yeri %18.1 oranla akciğerdi. Genel sağ kalım süresi 65 ay dı (95%CI 30-59). Pre-operatif, postoperatif, preoperatif+postoperatif kemoterapi alanlar ve diğer grup arasında sağ kalım süreleri açısından fark izlenmedi (sırasıyla 23ay, 36 ay, 28 ay 44 ay) (p=0.8). Radyoterapi uygulanan ve uygulanmayanlar arasında istatistiksel olarak anlamlı sağkalım farkı gözlenmedi (p=0.06). Tartışma: Os-teosarkom cerrahi, kemoterapi ve radyoterapi yöntemleriyle tedavi edilebi-len bir hastalıktır. Çalışmamızda hastalara uygulanan kemoterapi yöntemle-ri arasında sağ kalım farkı izlenmemiştir. Bu sonuçlar cerrahi, kemoterapi ve radyoterapiyide içeren multidisipliner tedavinin önemini ortaya koymaktadır.

    ABSTRACT: Paragangliomas are relatively rare chromaffin cell tumors which may be cured through resection. Patients with paragangliomas may develop metastatic diseases. There is no consensus regarding refractory chemotherapy for treatment of metastatic disease. In this report, we presented a case of a 43-year-old woman who was admitted to the hospital with a history of episodic headaches, diaphoresis, and weakness. Elevated plasma catecholamine levels and a right paraaortic mass were observed on computed tomography. The mass was excised, and a diagnosis of paraganglioma was confirmed. After 20 months of follow up, local recurrence and metastases were detected in the thorax, abdomen, and skeletal system. Plasma and urinary catecholamine levels were high. Chemotherapy was administered, and no improvement was observed. Therefore, following this palliative conventional chemotherapy, Sorafenib was administered for three months, and, finally, Positron Emission Tomography showed that the patient's lesions had completely regressed.

    ABSTRACT: BACKGROUND: Neurofibromatosis type 1 (NF1) is a genetic syndrome that predisposes patients to benign and malignant tumor development. Patients with NF1 develop multiple neurofibromas that can transform into aggressive sarcomas known as malignant peripheral nerve sheath tumors. In contrast, malignant tumors unrelated to the nervous system rarely coexist with neurofibromatosis. The aim of this article was to present four cases of adult NF1 patients with malignant tumors unrelated to the nervous system as well as a bibliographic search for papers describing these tumors in NF1, focusing on osteosarcomas, gastrointestinal stromal tumors (GISTs), leiomyosarcomas and somatostatinomas and their genetic alterations in NF1. METHODS: Search engines such as PubMed and MEDLINE were browsed for English-language articles since 1989 using a list of keywords, as well as references from review articles. Search terms were NF1, osteosarcoma, leiomyosarcoma, somatostatinoma and GIST. Data were summarized in a table at the end of the Results section. RESULTS: In our four NF1 cases, there were one osteosarcoma, one leiomyosarcoma, one somatostatinoma and GIST and one GIST. NF1 was diagnosed at an adult age when these patients were admitted to our oncology department. The results generated by the literature search yielded 75 articles about NF and GIST. We summarized the clinical characteristics of 43 patients with NF1 and somatostatinoma. Forty-five articles involving NF and osteosarcoma were found, and of these, 26 involved NF1; from these articles, we identified the clinical features of 8 patients. Twenty-five articles were found concerning NF1 and leiomyosarcoma, and of those, we summarized the clinical features of 15 patients. CONCLUSIONS: Here we reviewed somatostatinomas, GISTs, osteosarcomas and leiomyosarcomas occurring in NF1 patients. Patients with NF1 who present with gastrointestinal symptoms, should be carefully evaluated carefully with a high index of suspicion of potential GISTs, periampullary and duodenal tumors. Patients with pathological fractures or bone pain along with NF1 should be carefully screened for malignant bone tumors. Patients with NF1 can develop leiomyosarcoma less frequently than other malignancies, but the association of uterine leiomyoma and NF1 may not be fortuitous. Somatic mutations were defined for frequent tumors, including neurogenic tumors and GISTs but not for sarcomas due to the complexity of underlying mechanisms of the disease and tumorigenesis. Based on the findings; all NF patients can develop malignant tumors, including the less frequently observed ones. Therefore, we recommend that new genetic studies should be performed for rare malignancies in cases of NF1.

    ABSTRACT: Primary intrapulmonary thymomas are very rare. So far, research in the field has identified only 31 cases. In all databases, a total of two published articles describing primary intrapulmonary thymoma with myasthenia gravis were encountered between 1950 and 2010. We admitted a 58-year-old male patient with a mass in the right lower lobe of his lung. The tumor was excised, and histological findings were found to be consistent with Type AB thymoma. The patient was intubated due to respiratory distress during the postoperative period, and his acetylcholine receptor antibody was determined positive. He was diagnosed with myasthenia gravis. Pyridostigmine therapy and plasmapheresis were scheduled; yet, we could not begin therapy because of rapid deterioration of the patient's respiratory status due to myasthenia gravis and subsequently resulting in intubation-associated pneumonia. The patient's health rapidly worsened, and he died.

    ABSTRACT: Chronic myeloid leukemia (CML) is a clonal stem cell disorder, and imatinib is a small molecule inhibitor of Bcr-Abl tyrosine kinase (TK) used in cases with CML. Immediate and short-term side effects of this tyrosine kinase inhibitor (TKI) are well known, but the long-term side effects have not yet been clearly identified. Although an increased risk of secondary cancer in cases treated by imatinib was not found in two large series, secondary malignancies have been reported in some cases using TKIs, and this issue is important in daily clinical practice for clinicians. Here we report eight cases with neoplasias that developed during imatinib therapy and review secondary malignant disorders occurring during/after imatinib treatment.

    ABSTRACT: Background and Objectives: This study aimed to present the clinicopathological characteristics and treatment of patients with bladder carcinoma with sarcomatoid differentiation at our institution. Methods: Between 1995- 2009, 950 patients were followed-up for bladder carcinoma. Among them, 14 patients with sarcomatoid carcinoma were retrospectively reviewed, and their clinical, pathological features and treatment were recorded. Results: Median age of the patients was 65 years (range: 41-86 years), 12 (86%) being male and 2 (14%) female. All the patients presented with hematuria and 11 (88%) had a history of smoking. The tumor growth pattern was solid in 10 patients, papillary in 2, and mixed in 2. In all, 5 of the patients had urothelial carcinoma with sarcomatoid differentiation and 9 were diagnosed with sarcomatoid carcinoma. Five patients underwent radical cystectomy with ileal conduit surgery, 2 patients refused cystectomy, and 8 patients underwent re-TUR. Following diagnosis ,12 of the patients died in mean 10.7 months (range: 1-48 months). Conclusion: Urothelial carcinomas with sarcomatoid features are aggressive and are usually at advanced stage at the time of diagnosis. The outcomes of multimodal treatment are not satisfactory. Significant findings of the present study are that early diagnosis positively affect survival and that gemcitabine and cisplatin in combination can positively affect survival.

    ABSTRACT: Background: No factor has thus far been identified to predict the efficacy of bevacizumab therapy for colorectal cancer. We here therefore studied PTEN, VEGF, HER2 and p53 by immunohistochemistry as possible prognostic and predictive factors. Materials and Methods: A total of 34 retrospectively collected tumor samples were evaluated, all from patients receiving bevacizumab-based regimens. VEGF-A, PTEN, HER2, p53 were assessed and data was compared with clinicopathologic characteristics of patients and the bevacizumab response rate. Results: In this study, the median age of the 34 metastatic colorectal cancer patients was 55.5 (24-75), twelve (35.3%) being women and 22 (64.7%) men. PTEN, VEGF, HER2, p53 expressions were compared with bevacizumab response and other chacteristics of disease. Statistical significant differences were not found between bevacizumab response rates and different expression levels of VEGF, PTEN, HER2 and p53 (respectively p=0.256, p=0.832, p=0.189, p=0.131). However, a survival difference was noted in the VEGF expression negative group (median OS:55 months; 95%CI, 22-88 months) (p=0.01). There was no statistically significant OS difference in other groups (PTEN p=0.6, HER2 p=0.189, p53 p=0.13). Conclusions: We did not find any predictive factor for BV therapy in our study. VEGF negative expression could be an important prognostic factor in metastatic colorectal carcinoma.

    ABSTRACT: Capecitabine has shown significant antitumor activity against anthracycline/taxane refractory breast cancer and advanced colorectal carcinoma. The main drug-related adverse effects are palmar-plantar erythrodysesthesia (hand-foot syndrome), diarrhea and stomatitis. Dyslipidemia is a rare but important side effect of this drug. The mechanism of capecitabine-induced hypertriglyceridemia (CI-HTG) is unclear. It may be due to the decreased activities of lipoprotein lipase and hepatic triglyceride lipase. This report is associated with 2 patients who developed severe HTG when receiving capecitabine. Capecitabine was discountinued and antilipemic treatments were given and both cases are in follow-up with normal lipid levels. This report describes CI-HTG and possible pathogenetic mechanisms and the literature is reviewed.

    ABSTRACT: Background: Myeloid sarcoma rarely presents in the absence of systemic myeloid disease. Case Report: In this study, we present a case of intracerebral myeloid sarcoma with no diagnosis of any hematological disease in a 22-year-old male patient in whom brain magnetic resonance image revealed a meningioma. However, biopsy showed myeloid sarcoma. No myeloid disease was determined. The mass disappeared following 8 cycles of chemotherapy. In the literature, we determined only 8 similar cases cited between 1970 and 2011. Conclusion: Intracerebral myeloid sarcoma has currently no standard treatment and may be confused with a primary brain disease. Chemotherapy and/or radiotherapy are the most viable and widely used treatment modalities. Potential occurrence of hematological disease should also be closely followed due to conversion risks.

    ABSTRACT: Background: Soft tissue sarcomas (STS) must be managed with a team involving pathologists, radiologists, surgeons, radiation therapists and medical oncologists. Treatment modalities and demographic charasteristics of Turkish STS were analysed in the current study. Material-Methods: Primary adult STS followed between 1999- 2010 in Cukurova University Medical Faculty Department of Medical Oncology were analzied retrospectively Results: Of the total of 498 patients, 238 were male and 260 female. The most seen adult sarcomas were leomyosarcoma (23%). Localization of disease was upper extremity (8.8%), lower extremity (24.7%), head-neck 8.2%, thoracic 8%, retroperitoneal 5.6%, uterine 12.4%, abdominal 10%, pelvic region 3.6 and other regions 10%. Some 13.1% were early stage, 10.2% locally advanced, 8.2% metastatic and 12.2% recurrent disease. Patients were treated with neoadjuvant/adjuvant (12%) or palliative chemotherapy (7.2%) and 11.4% patients did not receive chemotherapy. Surgery was performed as radical or conservative. The most preferred regimen was MAID combination chemotherapy in the rate of 17.6%. The most common metastatic site was lung (18.1%). The overall survival was 45 months (95%CI 30-59), 36 months in men and 55 months in women, with no statistically significant difference (p=0.5). The survival rates were not different between the group of adjuvant and palliative chemotherapy (respectively 28 versus 18 months) (p=0.06), but radical surgery at 37 months was better than 22 months for conservative surgery (p=0.0001). No differences were evident for localization (p=0.152). Locally advanced group had higher overall survival rates (72 months) than other stages (p=0.0001). Conclusion: STS can be treated successfully with surgery, chemotherapy and radiotherapy. The survival rates of Turkish people were higher in locally advanced group; these results show the importance of multimodality treatment approach and radical surgery.

    ABSTRACT: Background: Neoadjuvant systemic chemotherapy is the accepted approach for women with locally advanced breast cancer. Anthracycline- and taxane-based regimens have been extensively studied in clinical trials and consequently are widely used. In this study aimed to research the complete response (pCR) rates in different regimens for neoadjuvant setting and determine associated clinical and biological factors. Methods: This study included 63 patients diagnosed with breast carcinoma among 95 patients that had been treated with neoadjuvant chemotherapy between 2007 and 2010. TNM staging system was used for staging. The histologic response to neoadjuvant chemotherapy was characterized as a pCR when there was no evidence of residual invasive tumor in the breast or axillary lymph nodes. Biologic subclassification using estrogen receptor (ER), progesterone receptor (PR), HER2 were performed. Luminal A was defined as ER+, PR+, HER2-; Luminal B tumor was defined as ER+, PR-, HER2-; ER+, PR-, HER2+; ER-, PR+, HER2-; ER+, PR+, HER2+, HER2 like tumor ER-, PR+, HER2+; and triple negative tumor ER, PR, HER2 negative. Results: Patients median age was 54.14 (min-max: 30-75). Thirty-two patients (50.8%) were premenapousal and 31 (49.2%) were postmenapousal. Staging was performed postoperatively based on the pathology report and appropriated imaging modalities The TNM (tumor, lymph node, metastasis) system was used for clinical and pathological staging. Fifty-seven (90.5%) were invasive ductal carcinomas, 6 (9.5%) were other subtypes. Thirty nine (61.9%) were grade II and 24 (38.1%) were grade III. Seven (11.1%) patients were stage II and 56 (88.9) patients were stage III. The patients were classified for ER, PR receptor and HER2 positivity. Seventeen patients had complete response to chemotherapy. Forty patients (63.5%) were treated with dose dense regimen (cyclophosphamide 600 mg/m2 and doxorubicine 60 mg/m every two weeks than paclitaxel 175 mg/m2 every two weeks with filgrastim support) 40 patients (48%) were treated anthracycline and taxane containing regimens. Thirteen patients (76%) from 17 patients with pCR were treated with the dose dense regimen but without statistical significance (p=0.06). pCR was higher in HER2(-), ER(-), grade III, premenopausal patients. Conclusion: pCR rate was higher in the group that treated with dose dense regimen, which should thus be the selected regimen in neoadjuvant setting. Some other factors can predict pCR in Turkish patients, like grade, menopausal status, triple negativity, percentage of ER positivity, and HER2 expression.

    ABSTRACT: Primary lymphoma of the breast is very rare especially in a male patient. Treatment alternatives include surgery, chemotherapy, immunotherapy and radiation. It is still controversial which combination is the best. Here, we report a male patient who presented with a left breast mass. The excisional biopsy was applied, and pathological assessment revealed marginal zone lymphoma. Both conventional computed tomography and 18)F-Fluorodeoxyglucose positron emission tomography/computed tomography were used for staging. The clinical stage was IIE for Ann Arbor staging and so local radiation following chemo immunotherapy was planned. Left-sided primary breast lymphoma in a male patient is a very rare entity. Treatment modalities are still controversial. Some authors believe that primary breast lymphomas have poor prognosis, and they must be treated aggressively with combined treatment modalities. Another important point is that 18)F-Fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET)/CT could be used for staging of disease and assessing treatment response in a patient with primary breast marginal zone lymphoma.

    ABSTRACT: Most commonly arising in the gastrointestinal and genitourinary tracts, extrapulmonary small-cell carcinoma is quite rare. Although its prognosis is very poor, complete remission or even cure can be achieved by combination of different treatment modalities. We report here a 32-year-old woman with a cutaneous gluteal mass diagnosed as small-cell carcinoma of the skin. Combination chemotherapy containing cisplatin and etoposide was started. Radiotherapy was administered after two courses of chemotherapy. Following radiotherapy, additional 4 courses of chemotherapy were given. She has been in remission for three years with no evidence of tumor recurrence.
