BackgroundWe aimed to evaluate retrospectively the correlation of loco-regional relapse (LRR) rate, distant metastasis (DM) rate, disease free survival (DFS) and overall survival (OS) in a group of breast cancer (BC) patients who are at intermediate risk for LRR (T1-2 tumor and 1-3 positive axillary nodes) treated with or without postmastectomy radiotherapy (PMRT) following modified radical mastectomy (MRM).MethodsNinety patients, with T1-T2 tumor, and 1-3 positive nodes who had undergone MRM received adjuvant systemic therapy with (n = 66) or without (n = 24) PMRT. Patient-related characteristics (age, menopausal status, pathological stage/tumor size, tumor location, histology, estrogen/progesterone receptor status, histological grade, nuclear grade, extracapsular extension, lymphatic, vascular and perineural invasion and ratio of involved nodes/dissected nodes) and treatment-related factors (PMRT, chemotherapy and hormonal therapy) were evaluated in terms of LRR and DM rate. The 5-year Kaplan-Meier DFS and OS rates were analysed.ResultsDifferences between RT and no-RT groups were statistically significant for all comparisons in favor of RT group except OS: LRR rate (3%vs 17%, p = 0.038), DM rate (12% vs 42%, p = 0.004), 5 year DFS (82.4% vs 52.4%, p = 0.034), 5 year OS (90,2% vs 61,9%, p = 0.087). In multivariate analysis DM and lymphatic invasion were independent poor prognostic factors for OS.ConclusionPMRT for T1-2, N1-3 positive BC patients has to be reconsidered according to the prognostic factors and the decision has to be made individually with the consideration of long-term morbidity and with the patient approval.

Although testicular germ cell tumors have become curable neoplasms, a better understanding of the clinicopathologic features is needed for the rare manifestations associated with treatment failure. We report a rare case of metastatic pure choriocarcinoma involving the small intestine arising from a testicular mixed germ cell tumor. In a patient who developed massive upper gastrointestinal hemorrhage during treatment, the intestinal metastases and focus of bleeding could only be determined by laparotomy. We propose an approach for the determination of subclinical intestinal metastases of testicular germ cell tumor; the case is discussed in light of similar reports in literature.

The adverse effects of regimes in cancer treatment have forced us to change to new targeted therapy options. Understanding these side effects, which can lead to discontinuation of the new therapy strategies, will allow the clinical management of these side effects and result in continuing therapies with effective medications. Bevacizumab, which is an IgG1 antibody against vascular endothelial growth factor, has side effects such as proteinuria, hypertension, venous and arterial thromboembolic events, and hemorrhage. This is the first reported case of dural sinus vein thrombosis, during the treatment with bevacizumab.

Background: Malignant melanoma is a highly unpredictable tumor that has capacity to metastasize to any organ. A better understanding is needed of the clinicopathologic features of metastatic melanoma and, in particular, of its rare manifestations. Case Report: A 33-year-old woman with a past medical history of malignant melanoma presented with symptoms of throat discomfort and bleeding. On physical examination, a dark pigmented lesion was observed on the right tonsil. Tonsillectomy was performed, and melanoma was diagnosed. Computed tomography of the thorax and abdomen revealed a filling defect in the right atrium and a 4-cm gallbladder mass. Echocardiography revealed a right atrial mass. No further metastasis was detected by whole body 18F-fluorodeoxyglucose positron emission tomography. Each metastasis was completely resected with clear margins. The pathologic diagnosis of the resected masses was malignant melanoma. 3 weeks after the final surgery, temozolomide was started. The patient has been followed up for 9 months after diagnosis of the first recurrence, and no new metastases have been detected. Conclusion: We report a case with synchronous tonsil, gallbladder, and heart metastases without any other common sites of metastasis of melanoma. The patient was successfully treated with aggressive surgery followed by temozolomide.

Background. Extrapulmonary small cell carcinomas (EPSCC) can clinically progress differently depending on the primary site of disease involvement. This review is focused on patients with small cell carcinoma (SmCC) exclusively localized in a lymph node or in multiple lymph nodes without any evidence of a primary tumor in any other organ. Methods. We searched the period 1980 to 2007 in the PubMed database and idendified 11 publications in the English language presenting at least one case of SmCC. In total 28 individual patients were included in the present study. They were scrutinized in terms of epidemiology, clinical presentation, staging, pathology, etiology, treatment and prognosis. Results. Characteristics such as age, gender and smoking were similar to those seen in other EPSCCs. Median survival was not reached (42+, range, 9.1 to 100 months). The survival rate was found to be 79% at 3 years. Seventy-seven percent of the patients had limited stage disease. These patients completely responded to surgical therapy, chemotherapy, radiotherapy or to a combination of these treatments. Seventy-one percent of the patients with limited stage SmCC localized in lymph nodes were recurrence-free during the study periods. Discussion. Our review patient group with SmCC localized in lymph nodes exhibited an excellent clinical behavior and survival results when compared to other patients with pulmonary and non-pulmonary SmCCs. SmCCs localized in lymph nodes may be a separate clinical entity.

BACKGROUND Combination chemotherapy of 5 fluorouracil (5-FU) and leucovorin (LV) with oxaliplatin, mainly FOLFOX regimens, has shown considerable antitumor activity and a tolerable toxicity profile in gastric cancer. The goal of this study was to retrospectively compare the efficacy and toxicity of modified FOLFOX-6 (mFOLFOX6) regimen in advanced gastric cancer (AGC) patients with good and poor performance status (PS). MATERIALS AND METHODS AGC patients receiving the mFOLFOX6 regimen including oxaliplatin 85 mg/m2, bolus of 5-FU 400 mg/m2 and LV 400 mg/m2 on the first day, followed by 2400mg/m2 of 5- FU as a continious infusion over 46 hour for first-line treatment were eligible for the study. RESULTS A total 58 patients with a median age of 59.5 (32-81) were included. The median follow up of the study was 9.2 months. Thirty patients (51.7%) with an ECOG PS 0-1 were assigned to the good PS arm, while 28 patients (48.3%) with ECOG PS 2 were in the poor PS arm. Overall response rates were 36.6 and 28.8%, respectively (p=0.91). Median PFS was 6.7 and 6.3 months in good PS and poor PS arms (p=0.50) and median OS was 9.6 and 10.4 months (p=0.55). As compared with good PS arm, poor PS arm was associated with more grade 3-4 neutropenia and anemia. Dose reduction and dose delays were also significantly higher. CONCLUSIONS In this study, mFOLFOX6 was similarly effective in both arms. Although hematologic toxicity was significantly higher in patients with poor PS, it remained manageable. Our results suggest that this regimen may be an effective treatment option for AGC patients with poor PS.

Spontaneous intracranial hypotension (SICH) is an entity, which is secondary to iatrogenic manipulation and breaching of dura. Postural headache in patients should be suspected, cranial magnetic resonance imaging (MRI) is essential for precise diagnosis. Hallmark of MRI is regular shape of pachymeningeal gadolinium enhancement and subdural effusion. It may mimic central nervous system (CNS) metastasis. Prevention of such cases from receiving cranial radiotherapy by misinterpretation of the gadolinium enhancement as CNS metastasis is an important issue. Capecitabine is an antineoplastic agent, of which metabolites can cross blood-brain barrier in CNS via epithelial tissue. It may cause decrease in CSF production. SICH might be the clinical reflection of this decrease in CSF production. Review of the English literature revealed limited data because of the very little experience with oncologic patients suffering from intracranial hypotension. We report a case of spontaneous intracranial hypotension during capecitabine treatment. Patient was completely well following drug discontinuation and supportive treatment.

Zafer Kocak; Mert Saynak; Fulya Oz-Puyan; Irfan Cicin; Rusen Cosar-Alas; Murat Caloglu; Gundeniz Altiay; Sernaz Uzunoglu

Tumours that metastasise to groin nodes most frequently originate in genital and reproductive organs, skin, rectum or anus, or urinary bladder. However, rare cases of inguinal metastases from tumours above the diaphragm have been reported and only three of them had an inguinal metastasis which was recognised antemortem and reported in detail in the English medical literature. The primary tumours of these cases were malignant mesothelioma, salivary duct and breast carcinoma. In this paper, we report a case of carcinoma of the lung metastatic to an inguinal lymph node as the only evidence of progressive lung cancer.

This study aimed to elucidate the clinical and prognostic characteristics of a homogeneous group of patients with cancer of unknown primary (CUP). Between 1999 and 2014, CUP was diagnosed in 159 (1.3%) of 11,742 cancer patients at Trakya University Hospital (Edirne, Turkey). Ninety-seven (61%) of the 159 patients were retrospectively reviewed. Among these, 61 (62.8%) patients with adenocarcinoma were included in this study. The most frequently predicted primary tumor site was the lung (37.7%), and 59% of the patients were smokers. There was a significant relationship between smoking and the lung as a potential primary cancer site (p = 0.042). The most frequent site of metastasis was the liver (60.7%). The median number of metastases per patient was two, but patients with liver metastases had a median of five metastases. The overall median survival time was 7 months. Median survival was significantly longer in patients with a predicted primary site than in patients without the predicted site (7 vs. 6 months, respectively; p = 0.038). When the patients with predicted ovarian and peritoneal tumors were excluded from the comparison, the statistical p value was still close to significant (p = 0.07). Multivariate analysis revealed that smoking, liver metastasis, serum alkaline phosphatase ≥92 U/L, and progression in response to chemotherapy were independent predictors of a poor prognosis. The present study identified several independent prognostic factors in patients with unknown primary adenocarcinomas who received chemotherapy. Smoking, the presence of liver metastasis, and response to chemotherapy were independent risk factors for both progression-free and overall survival.
