Justin D Oake, Douglas N Drover
Metastatic involvement of the penis is relatively infrequent. Metastasis of transitional cell carcinoma (TCC) is extremely rare. We report a case of bladder TCC with metastases to the penis that spares the urethra - a finding that, to the best of our knowledge, has not been previously reported. Of the documented mechanisms of metastatic transmission to the penis, we suspect the cause was retrograde lymphatic spread. In our case, a 59-year-old male presented to our clinic initially with phimosis and later developed gross hematuria...

Periampullary carcinoma metastases are usually located at regional nodes, adjacent organs, liver or lung. On the other hand, metastatic penile cancer is uncommon. Penile metastasis usually originates from pelvic region with prostate and bladder being the most frequent primary location. We present a very rare case of periampullary carcinoma with penile metastasis in a 49-year-old man. He initially presented with early ampullary type periampullary carcinoma and had pyloric preserving pancreatoduodenectomy and adjuvant chemotherapy...

A PSA-negative, advanced adenocarcinoma of the prostate is a rare finding. Expression of thyroid transcription factor-1 (TTF-1) in the tumour in combination with a previous medical history of lung adenocarcinoma could complicate the final diagnosis. To the best of our knowledge, we present the second case of a TTF-1-positive, acinar adenocarcinoma of the prostate.We present the case of a 65-year-old male with surgically treated lung adenocarcinoma; 3 years later we diagnosed adenocarcinoma of the bladder and prostate...

OBJECTIVE: To describe the geographic distribution patterns of the municipal incidence of the most common tumours in the Huelva province (Spain) as compared to the estimated incidence for all of Spain. METHODS: Relative risk (RR) was computed based on the conditional autoregressive model proposed by Besag, York and Mollié by applying the INLA tool to the cancer data for 2007-2011 for the following tumour locations: colon, rectum and anus (men and women); trachea, bronchia, and lungs, prostate and bladder in men; and breasts in women...

Sarcomas account for only 1% of adult solid tumours. Visceral sarcomas except Gastrointestinal Stromal Tumours (GIST) are rare and therefore little is known about the natural history and prognosis of these tumours. They tend to occur in older adults with no sex predilection and are characterized by an aggressive behaviour. Proper evaluation of these tumours is necessary because these are uncommon tumours which often present with advanced disease in an anatomically complex location. Since there are very few published studies on visceral sarcomas, the data is insufficient to suggest prognosis and optimum treatment strategies...

PURPOSE: To investigate hypoxia-guided dose-boosting for increased tumour control and improved normal tissue sparing using FMISO-PET images METHODS: Individual tumor-specific control probability (iTSCP) was calculated using a modified linear-quadratic model with rectal-specific radiosensitivity parameters for three limiting-case assumptions of the hypoxia / FMISO uptake relationship. (18) FMISO-PET images from 2 patients (T3N0M0) from the RHYTHM trial (Investigating Hypoxia in Rectal Tumours NCT02157246) were chosen to delineate a hypoxic region (GTV_MISO defined as tumor-to-muscle ratio > 1...

Rhabdomyosarcomas are malignant neoplasms with striated muscle differentiation. This is the most common type of soft-tissue sarcoma in children, but occurs rarely in adults. Its occurrence in liver is infrequent. We report a case of primary hepatic embryonal rhabdomyosarcoma in a 67-year-old man. The tumour was occupying the left lobe of the liver with large component of lesion seen bulging in left subhepatic space indenting over the stomach, compressing the pancreas and gall bladder. A percutaneous biopsy was performed which revealed embryonal rhabdomyosarcoma...

Hyperglycaemic influence on carcinogenesis and tumour progression is emerging as a link between diabetes and cancer. This work establishes the disturbed structural integrity of nucleosomal linker histone H1 by methyglyoxal (MG) and then correlates the role of modified H1 in the auto-immunopathogenesis of multiple cancers. MG modification caused a loss of free ε-amino groups in H1 and raised its β-sheet structural component with a consequence of non amyloid aggregation. It changed the folding-unfolding denaturation pattern of H1 and attached itself to the lysine residues of the protein eventually making up N(ε)-(carboxyethyl) lysine...

REVIEW
Antonio Lopez-Beltran, Gladell P Paner, Rodolfo Montironi, Maria R Raspollini, Liang Cheng
A handful of therapeutic procedures are used to treat malignancies of the urinary tract, most frequently intravesical immunotherapy or chemotherapy, but also neoadjuvant systemic chemotherapy. These treatment modalities produce morphological changes in the urothelium that can be mistaken for carcinoma; in particular, these therapies frequently mimic urothelial carcinoma in situ (CIS) urothelial dysplasia or true invasive neoplasia. Drugs such as mitomycin C used after transurethral resection of bladder tumour to reduce recurrences, bacillus Calmette-Guérin (BCG) intravesical immunotherapy to treat high-risk non-muscle-invasive bladder cancer and urothelial CIS and platin-based systemic chemotherapy to improve postcystectomy disease-specific survival are examples of therapy-related atypia seen in the urinary tract...

Esmee Iml Liem, Theo M de Reijke
PURPOSE OF REVIEW: The recurrence rate in patients with nonmuscle invasive bladder cancer is high, and the quality of transurethral resection of the bladder (TURB) tumour influences recurrence risk. We review new methods that aim to improve the effectiveness of TURB, and highlight studies of the past year. RECENT FINDINGS: Several approaches have been explored: bipolar resection is well tolerated and efficient; however, surgical outcomes are not clearly superior to monopolar resection; en-bloc resection seems feasible and well tolerated, and has the potential to improve the quality of tissue for histopathology; enhancement techniques such as photodynamic diagnosis, narrow band imaging, and Image1 S improve tumour detection, whereas photodynamic diagnosis reduces recurrence rates; high-resolution imaging modality such as confocal laser endomicroscopy may provide histopathologic information...

INTRODUCTION: Meningeal carcinomatosis is defined as tumour cells infiltration of leptomeninges and subarachnoid space. It is normally related with poor survival (2 - 5 months). The best multidisciplinary treatment for this condition is a matter of discussion. Patient's condition and the natural history of the disease should be considered in the decision making process. MATERIAL AND METHODS: Retrospective cohort analysis of patients submitted to Ommaya Reservoir placement due to systemic solid tumour meningeal carcinomatosis between 2006 and 2014...

Multicystic mesothelioma (MM) is a relatively rare tumour arising in the pelvic peritoneum of the tuboovarian region of young woman. Exceptionally, MM occurs on the serosal surfaces of various organs including kidney, bladder, lymph nodes, and liver. We report here the first case of MM wherein a 58-year-old woman with a previous history of endometriosis of the right ovary presented with a large multicystic mass of the spleen. The diagnosis of MM was made on a surgical specimen after splenectomy. A histopathologic examination is always necessary for the diagnosis of MM which should be differentiated from other lesions particularly from cystic lymphangioma...

Primary cancer arising from multiple organs is a well known fact. Synchronous tumours have been most commonly associated with kidney cancer. Bladder, prostate, colorectal and lung cancer are the most common synchronous primaries with Renal Cell Carcinoma (RCC) identified till date. We found metachronous tumours of breast with RCC in literature search which included both metastatic tumours as well second primaries. Overall, 25 cases of metastatic breast tumours and eight cases of second primary in previously treated RCC have been reported in the literature...

Castleman's disease (CD) also known as angiofollicular lymph node hyperplasia represents a group of uncommon non-clonal lymphoproliferation. We herein report a case of CD associated with carcinoma of the gall bladder. To the best of our knowledge, it is the first of its kind and has not been reported in the past. The hypothesis regarding the aetiopathogenesis of CD is that it is associated with interleukin-6 surges. This may be explained by the overproduction of IL-6 by tumour cells or IL-6 production due to a long-standing/smouldering localised inflammatory response...

Bladder cancer is a common cancer with particularly high recurrence after transurethral resection. Despite improvements in neoadjuvant chemotherapy, the outcome of patients with advanced bladder cancer has changed very little. In this study, the anti-tumour activities of a novel Polo-like kinase 1 (PLK1) inhibitor (RO3280) was evaluated in vitro and in vivo in the bladder carcinoma cell lines 5637 and T24. MTT assays, colony-formation assays, flow cytometry, cell morphological analysis and trypan blue exclusion assays were used to examine the proliferation, cell cycle distribution and apoptosis of bladder carcinoma cells with or without RO3280 treatment...
