Multicentric origin is incidence appears to have risen since suspected because of recurrence in operative diagnosis. Nomenclature and classification are detected because of dilatation of the branch ducts are involved. The epithelium typically forms papillary or pseudopapillary structures, but portions. The amount of mucin production varies widely, as does the degree of papillary growths are large, the dilated duct dilatation {97, 872}. Goblet or ducts may show localized excrescences Paneth cells may be present as a mani. A variety of invasive carcinomas may extend intrathan those seen in Paneth cells.

Areas of patients with hepatic metastases, and is necrosis and cystic degeneration may characterized by excessive secretion of be present. Occasionally, the neoplasm lipase into the serum, with clinical sympis found attached to the pancreatic surtoms including subcutaneous fat necroface. Peripheral blood such as duodenum, spleen, or major lobulated tumour occupies the tail of the pancreas. Adjacent cells carcinomas (see chapter on miscellaare joined by tight junctions. In polarized cells lacking luminal formations are cells, they are located in the apical cytoseparated by small vessels. Within these plasm, and the secretory contents may nests, cellular polarization is generally not be seen within the luminal spaces where evident, but there may be an accentua. In addition to typical zymogen arrangement of tumour cells may be in over 95% of cases; lipase is less comgranules, a second granule type, the present, with exceptional cases also monly identified (approximately 70% of irregular fibrillary granule, is detected showing a gyriform appearance . Pancreatic stone protein is ultrastructurally in many cases {302, 936, the neoplastic cells contain minimal to also commonly expressed . It has been suggested that moderate amounts of cytoplasm that areas, immunohistochemical staining for irregular fibrillary granules may represent may be more abundant in cells lining enzymes may show diffuse cytoplasmic a recapitulation of the fetal zymogen lumina. The cytoplasm varies from positivity, whereas the reaction product is granules, although attempts to document amphophilic to eosinophilic and is charrestricted to the apical cytoplasm in acithe presence of pancreatic enzymes acteristically granular, reflecting the presnar areas. In many Immunohistochemical markers of endohave been unconvincing {936, 938, instances, however, only minimal cytocrine and ductal differentiation may also 1032}.

Of these, the best characterized is zymogen granules in many examples of the mixed acinar-endocrine carcinoma acinar cell carcinoma, histochemical . In many mixed acinar-endocrine stains are relatively insensitive for docucarcinomas, the evidence for divergent menting acinar differentiation, and very differentiation is only provided by focal staining may be difficult to interpret immunohistochemical staining. Prognosis and predictive factors these neoplasms are aggressive, with a median survival of 18 months and a 5-year survival rate of less than 10% {739, 936}. Approximately 50% of patients have metastases at the time of diagnosis, and an additional 25% develop metastatic disease following surgical resection of the primary tumour . The most important prognostic factor is tumour stage, with patients lacking lymph node or distant metastases surviving longer . Patients with the lipase hypersecretion syndrome were shown to have a particularly short survival, because most of these patients had widespread metastatic disease. Most reported acinar-endocrine philia of the apical cytoplasm and an nar cell carcinoma may be somewhat carcinomas have been composed preincrease in nuclear:cytoplasmic ratio); less poor than that of ductal adenocarcidominantly of acinar elements based on these lesions are relatively common incinoma.

A number of congenital examples sition of the squamoid corpuscles varies have also been documented . A presence of heterologous stromal elements, including neoplastic bone and Aetiology cartilage, has been reported {127, 939}. B the cut surface of the apical cytoplasm in areas of the tumour Especially in the pediatric age group, neoplasm demonstrates a lobulated structure. At least focal 244 Tumours of the exocrine pancreas remains a separately definable neoplasm with characteristic histologic, immunohistochemical, and clinical features. Ultrastructure By electron microscopy, pancreatoblastomas generally exhibit evidence of acinar differentiation {939, 1758}, with relatively abundant rough endoplasmic reticulum and mitochondria, and apically located dense zymogen granules. The zymogen granules may be round and uniform, resembling those of non-neoplastic cells. In addition, irregular fibrillary granules similar to those described in acinar cell carcinomas may be found {936, 939}. In rare cases, dense-core neurosecretory-type granules and mucigen granules have also been observed . In most instances, the pronar formations are characteristic of panportion of cells expressing acinar markers creatoblastoma, and the solid areas Prognosis outnumbers the proportion expressing resemble the solid pattern of acinar cell Pancreatoblastomas are malignant endocrine or ductal markers. Nodal or hepatic metastases associated with elevations in the serum are also similar, with a relatively favorable are present in 35% of patients {782, 939}. Although this proposal is attraction of surgery and chemotherapy {894, this component . In the presence of metastatic disease or in adult patients with pancreatoblastomas, the outcome is usually fatal {312, 939}, the mean survival being 1. However, a favourable response to chemotherapy has been noted in some children {235, 2027}. Adler Definition It occurs predominantly in adolescent solitary masses (average size 8-10 cm; A usually benign neoplasm with predomigirls and young women (mean 35 years; range, 3-18 cm), and are often fluctuant.

Solid-pseudopapillary neoplasm is Localization uncommon but has been recognized There is no preferential localization within with increasing frequency in recent years the pancreas {1282, 1358}. It accounts for approximately 1-2% of all exocrine panClinical features creatic tumours {359, 941, 1280}. Usually, the neoplasms are found incidentally on routine physical examination or they cause abdominal discomfort and pain , occasionally after abdominal trauma . Jaundice is rare , even in tumours that originate from the head of the pancreas, and there is no. The T associated functional endocrine synpseudopapillary structures are lined by small drome. The papillary neoplasms have been reported tumour margin may contain calcifications. Common metastatic sites Administration of contrast medium results include regional lymph nodes, the liver, in enhancement of the solid tumour parts. Fine needle aspiration In large neoplasms, extensive necrosis is cytology performed under radiological typical and the preserved tissue is usualcontrol shows monomorphic cells with ly found in the tumour periphery under B round nuclei and eosinophilic or foamy the fibrous capsule. A the round hypodense tumour (T) replaces the tail of the cytoplasm {234, 2119, 2140}. More centrally there is a attached to the spleen, and shows haemorrhagic Macroscopy pseudopapillary pattern, and these comnecrosis. The neoplasms present as large, round, ponents often gradually merge into each 246 Tumours of the exocrine pancreas other. In both patterns, the uniform polyhedral cells are arranged around delicate, often hyalinized fibrovascular stalks with small vessels . In the solid parts, disseminated aggregates of neoplastic cells with foamy cytoplasm or cholesterol crystals surrounded by foreign body cells may be found. The spaces between the pseudopapillary structures are filled with red blood cells. The hyalinized connective tissue strands may contain foci of calcification and even ossification . Solid area containing cholesterol crystals and foreign body giant outside the cells. The round to oval nuclei have finely dispersed chromatin and are often grooved or indented. Mitoses are usually rare, but in a few instances prominent mitotic activity is observed . The neoplastic tissue is usually well demarcated from the normal pancreas, although a fibrous capsule may be absent and invasion of tumour cell nests into the surrounding pancreatic tissue may occur {1193, 1358}. Criteria of malignancy Although criteria of malignancy have not yet been clearly established, it appears that unequivocal perineural invasion, angioinvasion, or deep invasion into the surrounding tissue indicate malignant behaviour, and such lesions should be classified as solid-pseudopapillary carci. Consequently, benign appearing only involves small cell clusters or single to express S-100 {945, 1226, 1358}. Solid-pseudopapillary neoplasm 247 Usually, the staining for keratin is focal integrate, forming multilamellated vesinal trauma and rupture of the tumour and faint.

Other Definitions [0065] the following definitions are more general terms used throughout the present application. A salt is composed of one or more cations (positively charged ions) and one or more anions (negative ions) so that the salt is electrically neutral (without a net charge). Salts of the compounds as described herein include those derived from inorganic and organic acids and bases. Examples of acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, and perchloric acid, or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid, or malonic acid or by using other methods known in the art such as ion exchange. Other salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, / Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and N+(Ci^ alkyl) salts. Further salts include ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate, and aryl sulfonate. For example, Berge et a, describe pharmaceutically acceptable salts in detail in J. Pharmaceutically acceptable salts of the compounds as described herein include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, and perchloric acid or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid, or malonic acid or by using other methods known in the art such as ion exchange.

In certain embodiments, the molecular weight of a small molecule is at most about 1, 000 g/mol, at most about 900 g/mol, at most about 800 g/mol, at most about 700 g/mol, at most about 600 g/mol, at most about 500 g/mol, at most about 400 g/mol, at most about 300 g/mol, at most about 200 g/mol, or at most about 100 g/mol. In certain embodiments, the molecular weight of a small molecule is at least about 100 g/mol, at least about 200 g/mol, at least about 300 g/mol, at least about 400 g/mol, at least about 500 g/mol, at least about 600 g/mol, at least about 700 g/mol, at least about 800 g/mol, or at least about 900 g/mol, or at least about 1, 000 g/mol. In certain embodiments, the small molecule is a therapeutically active agent such as a drug. The small molecule may also be complexed with one or more metal atoms and/or metal ions. In this instance, the small molecule is also referred to as an "small organometallic molecule. In certain embodiments, the molecular weight of a large molecule is greater than about 2, 000 g/mol, greater than about 3, 000 g/mol, greater than about 4, 000 g/mol, or greater than about 5, 000 g/mol. In certain embodiments, the molecular weight of a large molecule is at most about 100, 000 g/mol, at most about 30, 000 g/mol, at most about 10, 000 g/mol, at most about 5, 000 g/mol, or at most about 2, 000 g/mol. In certain embodiments, the large molecule is a therapeutically active agent such as a drug. The large molecule may also be complexed with one or more metal atoms and/or metal ions. In this instance, the large molecule is also referred to as an "large organometallic compound. The term, as used herein, refers to proteins, polypeptides, and peptides of any size, structure, or function. Inventive proteins preferably contain only natural amino acids, although non-natural amino acids. Also, one or more of the amino acids in a protein may be modified, for example, by the addition of a chemical entity such as a carbohydrate group, a hydroxyl group, a phosphate group, a farnesyl group, an isofarnesyl group, a fatty acid group, a linker for conjugation or functionalization, or other modification. A protein may be naturally occurring, recombinant, synthetic, or any combination of these. Apolipoproteins also serve as enzyme cofactors, receptor ligands, and lipid transfer carriers that regulate the metabolism of lipoproteins and their uptake in tissues. Accordingly, a chimeric gene or chimeric construct may comprise regulatory sequences and coding sequences that are derived from different sources, or regulatory sequences and coding sequences derived from the same source, but arranged in a manner different than that found in nature. A "foreign" gene refers to a gene not normally found in the host organism, but which is introduced into the host organism by gene transfer. Foreign genes can comprise native genes inserted into a non-native organism, or chimeric genes. A "transgene" is a gene that has been introduced into the genome by a transformation procedure. The polynucleotides can be chimeric mixtures or derivatives or modified versions thereof, single-stranded or double-stranded. The oligonucleotide can be modified at the base moiety, sugar moiety, or phosphate backbone, for example, to improve stability of the molecule, its hybridization parameters, etc. A nucleotide sequence typically carries genetic information, including the information used by cellular machinery to make proteins and enzymes. As examples, phosphorothioate oligonucleotides may be synthesized by the method of Stein et a, Nucl. Vectors can be plasmid, viral, or others known in the art, used for replication and expression in mammalian cells. Alternatively, viral vectors can be used which selectively infect the desired tissue, in which case administration may be accomplished by another route. Non-limiting examples of such modifications include methylation, "caps", substitution of one or more of the naturally occurring nucleotides with an analog, and internucleotide modifications such as, for example, those with uncharged linkages. Polynucleotides may contain one or more additional covalently linked moieties, such as, for example, proteins. The polynucleotides may be derivatized by formation of a methyl or ethyl phosphotriester or an alkyl phosphoramidate linkage. Furthermore, the polynucleotides herein may also be modified with a label capable of providing a detectable signal, either directly or indirectly. Exemplary labels include radioisotopes, fluorescent molecules, biotin, and the like. By "recombinantly produced" is meant artificial combination often accomplished by either chemical synthesis means, or by the artificial manipulation of isolated segments of nucleic acids. Alternatively, it may be performed to join together nucleic acid segments of desired functions to generate a single genetic entity comprising a desired combination of functions not found in nature. Restriction enzyme recognition sites are often the target of such artificial manipulations, but other site specific targets. Plasmids are considered replicons, capable of replicating autonomously within a suitable host. The ability to hybridize will depend on both the degree of complementarity and the length of the antisense nucleic acid. One skilled in the art can ascertain a tolerable degree of mismatch by use of standard procedures to determine the melting point of the hybridized complex. Transcriptional gene silencing is the result of histone modifications, creating an environment of heterochromatin around a gene that makes it inaccessible to transcriptional machinery. Examples of particles include polymeric particles, single-emulsion particles, double-emulsion particles, coacervates, liposomes, microparticles, nanoparticles, macroscopic particles, pellets, crystals, aggregates, composites, pulverized, milled or otherwise disrupted matrices, and cross-linked protein or polysaccharide particles, each of which have an average characteristic dimension of about less than about 1 mm and at least 1 nm, where the characteristic dimension, or "critical dimension, " of the particle is the smallest cross-sectional dimension of the particle. A target tissue may be an abnormal or unhealthy tissue, which may need to be treated. A target tissue may also be a normal or healthy tissue that is under a higher than normal risk of becoming abnormal or unhealthy, which may need to be prevented. A "non-target tissue" is any biological tissue of a subject (including a group of cells, a body part, or an organ) or a part thereof, including blood and/or lymph vessels, which is not a target tissue. In some embodiments, treatment may be administered after one or more signs or symptoms of the disease have developed or have been observed. In other embodiments, treatment may be administered in the absence of signs or symptoms of the disease. For example, treatment may be administered to a susceptible subject prior to the onset of symptoms. Treatment may also be continued after symptoms have resolved, for example, to delay or prevent recurrence. As will be appreciated by those of ordinary skill in this art, the effective amount of a compound described herein may vary depending on such factors as the desired biological endpoint, the pharmacokinetics of the compound, the condition being treated, the mode of administration, and the age and health of the subject. The term "therapeutically effective amount" can encompass an amount that improves overall therapy, reduces or avoids symptoms, signs, or causes of the condition, and/or enhances the therapeutic efficacy of another therapeutic agent. The term "prophylactically effective amount" can encompass an amount that improves overall prophylaxis or enhances the prophylactic efficacy of another prophylactic agent. In such cases, the genetic disease will be heritable if it occurs in the germline. A proliferative disease may be associated with: 1) the pathological proliferation of normally quiescent cells; 2) the pathological migration of cells from their normal location. Angiogenesis is distinct from vasculogenesis, which is the de novo formation of endothelial cells from mesoderm cell precursors. The first vessels in a developing embryo form through vasculogenesis, after which angiogenesis is responsible for most blood vessel growth during normal or abnormal development. Angiogenesis is a vital process in growth and development, as well as in wound healing and in the formation of granulation tissue. However, angiogenesis is also a fundamental step in the transition of tumors from a benign state to a malignant one, leading to the use of angiogenesis inhibitors in the treatment of cancer. Angiogenesis may be chemically stimulated by angiogenic proteins, such as growth factors. A neoplasm or tumor may be "benign" or "malignant, " depending on the following characteristics: degree of cellular differentiation (including morphology and functionality), rate of growth, local invasion, and metastasis. A "benign neoplasm" is generally well differentiated, has characteristically slower growth than a malignant neoplasm, and remains localized to the site of origin. In addition, a benign neoplasm does not have the capacity to infiltrate, invade, or metastasize to distant sites. Exemplary benign neoplasms include, but are not limited to , lipoma, chondroma, adenomas, acrochordon, senile angiomas, seborrheic keratoses, lentigos, and sebaceous hyperplasias.

Prostate cancer is a heterogeneous disease have the highest prostate cancer incidence and death rates with differences in biology and clinical course. Some patients with low-risk disease do not require reported since the early 1990s. Important factors dying from other causes exceeds that of the cancer; on the associated with increased risk of prostate cancer include other hand, other patients are diagnosed with aggressive young age at diagnosis, the number of affected relatives, forms of prostate cancer and require multidisciplinary and the degree of relatedness of affected relatives (2).

He has experienced mild fatigue and mild diarrhea but overall, the treatment has been welltolerated. Prostate cancer is an androgen-dependent bone metastasis beyond the pelvis or axial skeleton). The research on hormone-sensitive pathway (abiraterone, enzalutamide); bone-targeting disease has focused on investigating optimal and more radiopharmaceutical agents (radium-223); and immunoeffective ways to use the available therapies.

Intratubular germ cell neoplasia (carcinoma in situ) is commonly found in patients In many ways, testicular cancer represents a break from at risk of testicular cancer; the risk of progression is 50% the common paradigm of solid malignancies.

Testicular cancer is most comdisease are each reported by about 10% of patients at mon in white males, with a lower incidence in Hispanics, presentation. Most of the remainder are sex cord stromal over the last several decades, mostly restricted to semitumors. The reasons for this increase are mia, or plasmacytoma are exceedingly rare and will not poorly understood. These data highlight the high testicular cancer in men with a previous diagnosis of tesprevalence of the most specific cytogenetic abnormality in ticular cancer is 1. The likelihood of having abnormally to support the diagnosis and initiate treatment. As patient with a diagnosis of pure seminoma should raise a consequence, they have been included as part of the questions about the accuracy of the diagnosis. If on the other hand the ing of his right testicle and scrotal ultrasound showed a 6-mm response is adequate and a complete response is achieved, well-defined hypoechoic lesion. Briefly, stage I includes history and physical examination, a scrotal ultrasound those patients with no regional node or metastasis, regardless should be pursued. Unfortunately, there is no absolute consensus atrophy) or in the setting of cryptorchidism. Most relapses will were present, an open inguinal approach should be elected occur within the first 2 years, which justifies a more frefor the biopsy. Similarly, other imaging studevery 6 months from years 4 to 7 and yearly thereafter. In fact, main advantages of surveillance is that it avoids unneca long-term, worldwide, retrospective analysis of >28, 000 essary treatment for a significant percentage of patients. Therefore, surveillance is preferred developing bladder, stomach, pancreas, and rectal cancer, if the patient will adhere to the close follow-up schedule. This In a pooled analysis of 638 patients from Europe, 2 facobservation prompted changes in the radiation dose and tors were found to be predictive of a higher relapse rate field with attempts to reduce toxicity while maintaining in patients managed by surveillance; tumor size >4 cm efficacy (risk of relapse <4%). Although the median follow-up a significant difference in the incidence of new contralaton this study (4. For example, the recent data supports the use of lower radiation doses, which patient described in this first case is a business man who are associated with similar relapse rates and decreased travels frequently making him unable to comply with a morbidity, compared to higher doses (11). In fact, 30% of patients undergoing retroperidemonstrated to be an independent risk factor for relapse. The major noma, but may be taken into consideration at the time of morbidity associated with this procedure is the infertility counseling a patient. Furthermore, this approach requires close followorchiectomy, based on the very low relapse rate (<3%) up (especially during the first 2 years) and reliable imaging seen in most studies. A radical inguinal orchiectomy was performed, with however, this approach is associated with high relapse rate pathology confirming the diagnosis of pure seminoma. Furthermore, several reports suggest that response to chemotherapy is significantly better for patients without prior exposure to radiation. Scrotal and inguinal node shielding is indicated this led to its use in combination with cisplatin and bleounless scrotal violation occurred during orchiectomy. Similarly, dose reductions in bleomycin or etoposide regardless of the size of the mass. Several reports showed that many of the masses is noted and confirmed with ultrasound. On discussion of further managethe residual tumor obliterates radiographic planes, mergment, he expresses that he does not want to have more ing with great vessels, psoas muscles, and retroperitoneal children and, moreover, he is concerned about long-term structures.
