A 70-year-old man was referred to our department for further examination and treatment of a painless penile mass of about 2cm. The patient first noticed the mass onlya few weeks before presentation. Diagnostic biopsy was interpreted as leiomyosarcoma. Through systemic examinations the clinical stage of his disease was diagnosed as cT2N0M0 and we performed total penectomy. Histopathological examination for the totallyresected tissue disclosed the concomitant presence of regions compatible to squamous cell carcinoma and the results of immunohistochemistrywere compatible with the diagnosis of squamous cell carcinoma, sarcomatoid subtype of the penis...

The incidence rate of multiple primary tumors is 37% in all types of cancer. A patient diagnosed with primary cancer is 1.29 times more likely to develop an additional primary cancer when compared with the general population. Furthermore, in patients diagnosed with primary cancer, the possibility of a secondary malignancy in the same or different organ is increased. Following the identification of a secondary tumor, the risk of relapse or metastasis must be considered. The present study reports the case of a 76-year-old man who was admitted to Sakarya University Training and Research Hospital (Sakarya, Turkey) with swelling of the head, which had been apparent for 15 days...

Carcinomas of the lung with benign osteoclast-like giant cells are rare. A literature search showed only 8 previously reported examples. These tumors resemble a giant cell tumor of bone. Many of these tumors, which occur in most epithelium-containing organs, are composed of an undifferentiated, sarcomatoid component that contains benign osteoclast-like giant cells and a conventional carcinoma. In some tumors the epithelial origin may be revealed by immunohistochemistry only; others lack any evidence of an epithelial component...

Background. The prognostic significance of the neutrophil-to-lymphocyte ratio (NLR) in nonmetastatic renal cell carcinoma (non-mRCC) is controversial, although NLR has been established as a prognostic factor in several cancers. The objective of our study was to assess the prognostic significance of preoperative NLR in non-mRCC, based on a large, multicenter cohort analysis. Methods. Totally, 1,284 non-mRCC patients undergoing surgery were enrolled from six institutions between 2000 and 2014. Recurrence-free survival (RFS) and cancer-specific survival (CSS) were calculated, and the prognostic significance of NLR was evaluated...

BACKGROUND: Some trials recently demonstrated the benefit of targeted treatment for malignant disease; therefore, adequate tissues are needed to detect the targeted gene. Pleural biopsy using flex-rigid pleuroscopy and pleural effusion cell block analysis are both useful for diagnosis of malignancy and obtaining adequate samples. The purpose of our study was to compare the diagnostic utility between the two methods among patients with malignant pleural disease with effusion. METHODS: Data from patients who underwent flex-rigid pleuroscopy for diagnosis of pleural effusion suspicious for malignancy at the National Cancer Center Hospital, Japan between April 2011 and June 2014 were retrospectively reviewed...

Pulmonary sarcomatoid carcinoma is a rare subtype of non-small cell lung cancer with a poor prognosis. We herein report on a case of pulmonary sarcomatoid carcinoma that was treated successfully by concurrent chemoradiotherapy. A 65-year-old man was diagnosed to have pulmonary pleomorphic carcinoma (clinical T4N2M0 stage IIIB). He received concurrent chemoradiotherapy (60 Gy of radiotherapy in 30 fractionations and two courses of chemotherapy with carboplatin and paclitaxel). After chemoradiotherapy, a significant reduction of the tumor size was observed...

Sarcomatoid carcinoma of the thymus is extremely rare. An operation remains the only effective treatment for this disease. We report a case of complete resection of thymic sarcomatoid carcinoma through a total aortic arch replacement and left upper lobectomy at our institution. Our aggressive operation was very effective, and the patient has experienced no recurrence in the 3 years since his operation.

PURPOSE: To assess the prognostic significance of sarcomatoid differentiation for surgically treated metastatic renal cell carcinoma (mRCC). METHODS: Patients undergoing cytoreductive nephrectomy for mRCC in our center between 2006 and 2014 were included. All enrolled patients were separated into two groups according to the presence of sarcomatoid differentiation. Clinical and pathological variables were recorded. Student's t test or Chi-square test was applied to compare them...

Liver transplantation (LT) for hepatocellular carcinoma (HCC) at Kaohsiung Chang Gung Memorial Hospital mainly relies on live donor LT (LDLT). Owing to taking the risk of LD, we are obligated to adopt strict selection criteria for HCC patients and optimize the pre-transplant conditions to ensure a high disease-free survival similar to those without HCC, even better than deceased donor LT (DDLT). Better outcomes are attributed to excellent surgical results and optimal patient selection. The hospital mortality of primary and salvage LDLT are lower than 2% in our center...

A 71-year-old man presented with hemothorax with cough, sputa and worsening dyspnea. On chest X-ray and computed tomography(CT), a huge tumor in the right upper lobe with hematoma and small amount of gas suggesting hemopneumothorax was revealed. No apparent lymphadenopathy nor intrapulmonary metastases were observed. The tumor showed a little enhancement on the contrastenhanced CT. Then the resction of the tumor was performed, and the pathological evaluation revealed a carcionosarcoma (adenocarcinoma+osteosarcoma) pT3N0 (stage II B) G4 pl2...

Micropapillary morphology in invasive urothelial carcinoma is an established predictor of aggressive disease. It is unknown, however, if prominent retraction is associated with more aggressive disease in the absence of classic micropapillary morphology. We reviewed a retrospective series of 309 radical cystectomy specimens with clinical follow-up data, and documented the presence or absence of invasive urothelial carcinoma with "prominent retraction clefts," defined as invasive carcinoma with retraction involving the majority of invasive tumor nests in at least one 100X field, but without classic micropapillary morphology...

The gene encoding phosphatidylinositol 3-kinase catalytic subunit α-isoform (PIK3CA, p110α) is frequently activated by mutation in human cancers. Based on detection in some breast cancer precursors, PIK3CA mutations have been proposed to have a role in tumor initiation. To investigate this hypothesis, we generated a novel mouse model with a Cre-recombinase regulated allele of p110α (myristoylated-p110α, myr-p110α) along with p53(fl/fl) deletion and Kras(G12D) also regulated by Cre-recombinase. After instillation of adenovirus-expressing Cre-recombinase into mammary ducts, we found that myr-p110α accelerated breast tumor initiation in a copy number-dependent manner...

BACKGROUND: VEGF-targeted therapy has become the mainstay of treatment for majority of mRCC patients. For most patients, benefit is short-lived and therefore treatment remains palliative in intent. HD IL2 is an effective immunotherapy treatment capable of durable remission in some patients but its unselected use has been difficult due to its modest response rate and considerable adverse effects. Using set pathology criteria as a selection tool in clinical practice, we have been able to show improved outcomes in our previous report...

Malignant transformation of fibrous dysplasia (FD) is exceedingly rare, occurring in <1% of all FD cases, and has been described in both monostotic and polyostotic forms of this entity. We report a case of a large proximal femur mass arising in a 45-year-old man. The biopsy revealed a high-grade pleomorphic malignancy that focally expressed multiple keratins. Based on the presence of keratin immunoreactivity, the morphologic differential diagnosis included metastatic sarcomatoid carcinoma. However, review of the clinical information revealed a history of polyostotic FD, and imaging findings were compatible with malignant transformation of FD...

BACKGROUND: Sarcomatoid urothelial carcinoma (SUC) is a rare malignant neoplasm of the urinary bladder comprising 0.2-0.6 % of all histological bladder tumor subtypes. It presents as a high-stage malignancy and exhibits aggressive biological behavior, regardless of the treatment employed. It is defined as histologically indistinguishable from sarcoma and as a high-grade biphasic neoplasm with malignant epithelial and mesenchymal components. The mean age of patients presenting with SUC is 66 years, and the male-to-female ratio is 3:1...

Availability of lung cancer models that closely mimic human tumors remains a significant gap in cancer research, as tumor cell lines and mouse models may not recapitulate the spectrum of lung cancer heterogeneity seen in patients. We aimed to establish a patient-derived tumor xenograft (PDX) resource from surgically resected non-small cell lung cancer (NSCLC). Fresh tumor tissue from surgical resection was implanted and grown in the subcutaneous pocket of non-obese severe combined immune deficient (NOD SCID) gamma mice...

BACKGROUND: Pulmonary sarcomas are uncommon accounting for 0.5 % of all primary lung cancers. Undifferentiated sarcomas account for up to 20 % of soft tissue sarcomas. A lung tumor revealed to be an undifferentiated sarcoma with epithelioid features has never been reported in the literature. CASE PRESENTATION: A 61-year-old white Moroccan man presented with 2 months' history of hemoptysis and dyspnea. Chest computed tomography showed a cystic mass involving the lower field of his right lung evoking first a hydatid cyst...
