Abstract
BACKGROUND The development of chemoresistance to paclitaxel and carboplatin represents a major therapeutic challenge in ovarian cancer, a disease frequently characterized by malignant ascites and extrapelvic metastasis. Microtentacles (McTNs) are tubulin-based projections observed in detached breast cancer cells. In this study, we investigated whether ovarian cancers exhibit McTNs and characterized McTN biology. METHODS We used an established lipid-tethering mechanism to suspend and image individual cancer cells. We queried a panel of immortalized serous (OSC) and clear cell (OCCC) cell lines as well as freshly procured ascites and human ovarian surface epithelium (HOSE). We assessed by Western blot β-tubulin isotype, α-tubulin post-translational modifications and actin regulatory proteins in attached/detached states. We studied clustering in suspended conditions. Effects of treatment with microtubule depolymerizing and stabilizing drugs were described. RESULTS Among cell lines, up to 30% of cells expressed McTNs. Four McTN morphologies (absent, symmetric-short, symmetric-long, tufted) were observed in immortalized cultures as well as ascites. McTN number/length varied with histology according to metastatic potential. Most OCCC overexpressed class III ß-tubulin. OCCC/OSC cell lines exhibited a trend towards more microtubule-stabilizing post-translational modifications of α-tubulin relative to HOSE. Microtubule depolymerizing drugs decreased the number/length of McTNs, confirming that McTNs are composed of tubulin. Cells that failed to form McTNs demonstrated differential expression of α-tubulin- and actin-regulating proteins relative to cells that form McTNs. Cluster formation is more susceptible to microtubule targeting agents in cells that form McTNs, suggesting a role for McTNs in aggregation. CONCLUSIONS McTNs likely participate in key aspects of ovarian cancer metastasis. McTNs represent a new therapeutic target for this disease that could refine therapies, including intraperitoneal drug delivery.

Abstract
Serous cavity may be involved by any neoplasm, including very rare examples of involvement by central nervous system tumors leading to a malignant effusion. The serous cavity lining is rich in lymphatics with lymphatic lacunae opening directly through narrow gaps (stoma) in the lining. Carcinomas mainly metastasize to serosa via the lymphatic vessels, which may be blocked leading to effusion. Primary carcinomas of organs such as lung, intestines, liver, ovary, etc., lined by serosal membranes may spread by direct extension, resulting in malignant effusions. As standard of practice, unless specified, cytopathologic examination of serous effusions implies detection of malignant cells.
As compared to a surgical biopsy from a small focal area of an extensive serosal surface, effusion fluid from respective cavity exfoliates the cells from the entire serosal surface with minimal chance of sampling artifact. Because of this, effusion fluid cytology generally provides a higher diagnostic yield as compared to biopsy of the serous lining, as demonstrated by some studies. However, various challenges related to effusion fluid cytology makes the interpretation of effusion fluid cytology a field with potential misinterpretations, especially for those without proper experience or training.
Developing and following a methodical approach is important for appropriate cytologic examination of effusion fluids. Proper approach may achieve definitive interpretation even without ancillary tests. However, lack of appropriate approach and processing may introduce a significant variation in interpretation due to combination of well-recognized diagnostic pitfalls, which may lead to lower reproducibility and even serious misinterpretations.
Current review discusses in brief appropriate approach to processing and evaluating effusion fluid cytology for metastatic carcinoma. At general level, this is comparable to that of other specimens; however, it is critical to modify with reference to the limitations associated with effusion cytology.

Abstract
Primary ovarian mesothelioma is a rare, aggressive neoplastic disease with a poor prognosis. At onset, the tumor is only rarely limited to the ovaries and usually already widespread in the peritoneum. The rarity of this entity and the difficulties differentiating it from either ovarian carcinoma or peritoneal mesothelioma may lead to frequent misdiagnoses and may raise some concerns about its histogenesis. Thus, reporting such rare cases is fundamental to gain greater awareness of this neoplasm and try to answer unsolved questions. Herein, we described four cases of histological diagnoses of ovarian mesothelioma extrapolated by the regional mesothelioma register of Apulia (southern Italy). In all cases, a detailed medical history was collected according to national mesothelioma register guidelines. A broad panel of antibodies was used for immunohistochemistry to confirm the diagnoses. Moreover, ovarian tissue samples were also examined by transmission and scanning electron microscopy, detecting asbestos fibers and talc crystals in two cases. Because of the few cases described, we reviewed the English literature in the Medline database, focusing on articles about ovarian mesothelioma "misclassification", "misdiagnosis", "diagnostic challenge" or "diagnostic pitfall" and on unsolved questions about its histogenesis and possible risk factors.

Abstract
Asbestos recently returned to the spotlight when Johnson & Johnson halted sales of baby powder due to lawsuits claiming that the talc in baby powder may have been contaminated with asbestos, which has been linked to the risk of ovarian cancer development. Although talc and asbestos have some structural similarities, only asbestos is considered causally associated with ovarian cancer by the WHO's International Agency for Research on Cancer. While it is useful to understand the types and properties of asbestos and its oncologic biology, the history of its association with ovarian cancer is largely based on retrospective observational studies in women working in high asbestos exposure environments. In reviewing the literature, it is critical to understand the distinction between associative risk and causality, and to examine the strength of association in the context of how the diagnosis of ovarian cancer is made and how the disease should be distinguished from a similar appearing but unrelated neoplasm, malignant mesothelioma. Based on contextual misinterpretation of these factors, it is imperative to question the International Agency for Research on Cancer's assertion that asbestos has a clear causal inference to ovarian cancer. This has important clinical implications in the way patients are conceivably counseled and provides motivation to continue research to improve the understanding of the association between asbestos and ovarian cancer.

Abstract
Primary peritoneal carcinoma (PPC) is a type of rare malignant epithelial tumor. Metastasis from PPC to breast has been rarely reported. PPC originates de novo from the peritoneal tissues rather than invasion or metastasis from adjacent or remote organs. PPCs have been implicated in many cases of carcinomas of unknown primary origin. It is similar to ovarian cancer (OvCa), because it shares the same common embryonic origin, the coelomic epithelium (mesodermal origin). The mechanism of oncogenesis remains elusive. In this article, we report a rare case of PPC in a patient 10 years after total abdominal hysterectomy and bilateral salpingooophorectomy for uterine leiomyoma, which was widely spread in the abdomen and metastasized to the colon, liver and distant organs including breast. The treatment is similar to that of primary ovarian cancer. We also reviewed the primary peritoneal cancer metastatic to breast and discuss the possible mechanisms and biology of primary peritoneal cancer, using experimental and animal model.

Abstract
Background Carcinoma of the recto-vaginal septum is a quite rare location and related to peritoneal and primary ovarian carcinomas. There are only few reports in the literature with a very poor prognosis. Case presentation Here we report the case of a 63 years old woman with past medical history of left oophorectomy presenting with a pelvic pain. The magnetic resonance imaging (MRI) demonstrated a 10 cm mass located in the recto-vaginal septum. A block resection was performed allowing the retrieval of a 10 cm solid tumor of the recto-vaginal septum. Peritoneal biopsies and the right ovary were normal the final diagnosis was cystadenocarcinoma of the recto-vaginal septum. The patient received adjuvant chemotherapy and displays no sign of recurrence 36 months after diagnosis. Conclusion The management of recto-vaginal septum carcinoma with en bloc resection should be performed to avoid peritoneal spread and improve prognosis.

Abstract
Peritoneal origin serous papillary carcinoma is an uncommon primary malignancy occurring in the abdominal or pelvic peritoneum lining. It is characterized by peritoneal carcinomatosis with massive ascites, uninvolved or minimally involved ovary, and is histologically indistinguishable from ovarian serous tumors. Better recognition of this phenomenon in recent years has contributed to an increasing diagnostic frequency. We describe a rare case of peritoneal origin serous papillary carcinoma with unusual clinical presentations involving a solitary primary tumor originating from the peritoneal lining of the sigmoid colonal mesentery, without pelvic lymph node involvement or distant metastasis. Because of the location and morphological similarity, it was misdiagnosed as an ovarian malignancy. We aim to assist in the diagnosis of this disease with the following case report, thereby improving the management of patients with this condition.

Abstract
The diagnosis of mesothelioma is not always straightforward, despite known immunohistochemical markers and other diagnostic techniques. One reason for the difficulty is that extrapleural tumors resembling mesothelioma may have several possible etiologies, especially in cases with no meaningful history of amphibole asbestos exposure. When the diagnosis of mesothelioma is based on histologic features alone, primary mesotheliomas may resemble various primary or metastatic cancers that have directly invaded the serosal membranes. Some of these metastatic malignancies, particularly carcinomas and sarcomas of the pleura, pericardium and peritoneum, may undergo desmoplastic reaction in the pleura, thereby mimicking mesothelioma, rather than the primary tumor. Encasement of the lung by direct spread or metastasis, termed pseudomesotheliomatous spread, occurs with several other primary cancer types, including certain late-stage tumors from genetic cancer syndromes exhibiting chromosomal instability. Although immunohistochemical staining patterns differentiate most carcinomas, lymphomas, and mestastatic sarcomas from mesotheliomas, specific genetic markers in tumor or somatic tissues have been recently identified that may also distinguish these tumor types from asbestos-related mesothelioma. A registry for genetic screening of mesothelioma cases would help lead to improvements in diagnostic criteria, prognostic accuracy and treatment efficacy, as well as improved estimates of primary mesothelioma incidence and of background rates of cancers unrelated to asbestos that might be otherwise mistaken for mesothelioma. This information would also help better define the dose-response relationships for mesothelioma and asbestos exposure, as well as other risk factors for mesothelioma and other mesenchymal or advanced metastatic tumors that may be indistinguishable by histology and staining characteristics.

Abstract
Extraovarian primary peritoneal serous papillary carcinoma (EOPPC) has a similar clinical presentation to that of ovarian cancer in advanced stages, such as peritoneal dissemination and a large amount of ascites, while EOPPC with a solitary tumor is very rare. We report here a 47-year-old Japanese woman with solitary form of EOPPC mimicking a liver tumor. Ovaries of both sides had no malignant lesion, which was histologically confirmed. Histological examination revealed that the tumor was located at the right diaphragm and partially invaded into the liver, and papillary or ductal proliferation of the tumor cells with an occasional appearance of psammoma bodies was detected. Immunohistologically, the tumor cells were positive for CA 125 and Ber-EP4 and negative for D2-40 or calretinin, ruling out the possibility of mesothelioma, and the diagnosis of the tumor was EOPPC. After the operation, the patient received chemotherapy with carboplatin and paclitaxel, but died 10 months later due the progression of recurrence. The present case is very rare form of EOPPC without any ascites or peritoneal dissemination.

Abstract
OBJECTIVE A recent Monographs Working Group of the International Agency for Research on Cancer (IARC) concluded that there is sufficient evidence for a causal association between exposure to asbestos and ovarian cancer. We performed a meta-analysis to quantitatively evaluate this association. DATA SOURCES Searches of PubMed and unpublished data yielded a total of 18 cohort studies of women occupationally exposed to asbestos. DATA EXTRACTION Two authors independently abstracted data; any disagreement was resolved by consulting a third reviewer. DATA SYNTHESIS All but one study reported standardized mortality ratios (SMRs) comparing observed numbers of deaths with expected numbers for the general population; the exception was a study that reported standardized incidence ratios. For simplicity, we refer to all effect estimates as SMRs. The overall pooled SMR estimate for ovarian cancer was 1.77 (95% confidence interval, 1.37-2.28), with a moderate degree of heterogeneity among the studies (I2 = 35.3%, p = 0.061). Effect estimates were stronger for cohorts compensated for asbestosis, cohorts with estimated lung cancer SMRs > 2.0, and studies conducted in Europe compared with other geographic regions. Effect estimates were similar for studies with and without pathologic confirmation, and we found no evidence of publication bias (Egger's test p-value = 0.162). CONCLUSIONS Our study supports the IARC conclusion that exposure to asbestos is associated with increased risk of ovarian cancer.

Abstract
In this article, we report a case of primary squamous cell carcinoma of the salpinx (PSCCS) with immunohistochemical and molecular studies to evaluate the phenotype and define the etiopathogenesis of this neoplasm. A 77-year-old woman, 38 years postmenopausal, was admitted to the Department of Obstetrics and Gynecology for ascites. Her clinical history showed breast carcinoma and left salpingooophorectomy as a result of extrauterine pregnancy. Cytological examination of the free peritoneal fluid showed clusters of malignant cells consistent with ovarian carcinoma. Transvaginal ultrasonography and a pelvic computed tomography scan disclosed a right pelvic mass with solid and cystic areas, measuring 3.222.3 cm. The patient underwent exploratory laparotomy. Intraoperative findings showed a mass that had replaced the salpinx and enveloped the ovary and ureter. The surface of the omentum was covered in small white nodules. Pathological examination showed that the right pelvic mass corresponded to PSCCS, whereas the omental white nodules were primary serous carcinoma. On immunohistochemical analysis, the tubal neoplasm showed positivity to Ca-125, keratin 14, and p63 and negativity to WT1 and p16. The hyper-expression of the p53 protein was evident as nuclear positivity. Molecular study by polymerase chain reaction amplification of the tumor DNA did not show any signal for human papilloma virus DNA. In summary, in this case we showed that the PSCCS was not due to human papilloma virus infection, but in all probability due to other pathogenetic mechanisms that cause a mutation of the p53 tumor-suppressor gene.

Abstract
INTRODUCTION Animal studies have suggested an association between asbestos and ovarian cancer, and asbestos fibers have been detected in human ovaries. Sexual intercourse may introduce asbestos fibers into the vagina and to the cervix and ovaries. Occupational cohorts have reported excess mortality from reproductive cancers, but exposure-response relationships are inconsistent. We examine the incidence and exposure-response relationships of these cancers among 2,968 women and girls exposed to blue asbestos at Wittenoom, Western Australia. METHODS 2,552 women were residents of the town and 416 worked for the asbestos company (Australian Blue Asbestos). Standardized incidence ratios compared the Wittenoom women with the Western Australian population. A nested case-control design and conditional logistic regression examined exposure-response relationships. RESULTS Ovarian (standardized incidence ratio, 1.27), cervical (standardized incidence ratio, 1.44), and uterine cancer (standardized incidence ratio, 1.23) increased but not statistically significantly among the Wittenoom women compared with the Western Australian population. Among the Australian Blue Asbestos workers, cervical cancer was twice that of the Western Australian population (standardized incidence ratio, 2.38), but ovarian cancer was less (standardized incidence ratio, 0.65). Women who first arrived at Wittenoom aged >or=40 years had an odds ratio of 13.9 (95% confidence interval, 2.2-90.2) for cervical cancer compared with those aged <15 years at first arrival. Women who lived with or washed the clothes of an Australian Blue Asbestos worker did not have an increased risk for any of the gynecologic or breast cancers. DISCUSSION There is no consistent evidence of an increased risk for gynecologic and breast cancers among the women from Wittenoom. Ovarian cancers and peritoneal mesotheliomas were not misclassified in this cohort.

Abstract
Virtually all primary peritoneal carcinomas (PPCs) are of serous papillary type. We report an unusual histologic type of PPC composed of anaplastic giant cells, which exhibited an aggressive clinical course. A 72-year-old woman presented with lower abdominal pain. Computed tomography showed a diffuse omental thickening. The patient underwent an exploratory laparotomy with omentectomy, total hysterectomy, bilateral salpingo-oophorectomy, and appendectomy. Pathologic examination revealed extensive omental replacement by tumor but only superficial surface cortical involvement of both ovaries, a disease distribution consistent with a typical müllerian-derived PPC. However, this neoplasm was composed of diffuse anaplastic tumor giant cells, rather than serous carcinoma, which is the usual histologic type encountered in PPC. The patient died within 1 month after surgery. We report this unusual histologic variant of PPC to raise awareness that anaplastic giant cell carcinoma may arise in the pelvic peritoneum as a primary tumor.

Abstract
Background Women that carry germ-line mutations for BRCA1 or BRCA2 genes are at an increased risk of developing breast, ovarian and peritoneal cancer. Primary peritoneal carcinoma is a rare tumour histologically identical to papillary serous ovarian carcinoma. Risk-reducing surgery in the form of mastectomy and oophorectomy in premenopausal women has been recommended to prevent breast and ovarian cancer occurrence and decrease the risk of developing primary peritoneal cancer. Case presentation We present a case report of a woman with a strong family history of breast cancer who underwent risk-reducing surgery in the form of bilateral salpingo-oophorectomy following a mastectomy for a right-sided breast tumour. Following the finding of a BRCA1 mutation, a prophylactic left-sided mastectomy was performed. After remaining well for twenty-seven years, she presented with rectal bleeding and altered bowel habit, and was found to have a secondary cancer of the sigmoid colon. She was finally diagnosed with primary papillary serous carcinoma of the peritoneum (PSCP). Conclusion PSCP can present many years after risk-reducing surgery and be difficult to detect. Surveillance remains the best course of management for patients with known BRCA mutations.

Abstract
The purpose of this study was to compare the effect of paclitaxel plus platinum-based chemotherapy in the treatment of extraovarian peritoneal serous papillary carcinoma (EPSPC) and ovarian serous papillary cancer (OSPC). Only the patients treated with initial surgery plus postoperative adjuvant chemotherapy and having FIGO stage IIIC disease with omental and/or peritoneal involvement were analyzed. Thirty-two patients with EPSPC and 43 with OSPC were included in this study. The median age, mean CA-125, and volume of ascitis were higher in patients with EPSPC. There was no significant difference between the two groups with respect to other prognosticators. The median overall survival (OS) durations were 30 months (95% CI 24.8-35.3) in patients with EPSPC and 28 months (95% CI 21.1-34.9) in those with OSPC (P= 0.35). The 3-year OS rates in the patients and controls were 28% and 31%, respectively (P= 0.84). In patients with EPSPC, only optimal cytoreduction was significantly related to progression-free survival and OS durations as a prognostic factor. In the EPSPC group, 65.5% of the patients (19/29) had lymphatic involvement, compared to 88.4% (38/43) in the OSPC group (P= 0.02). As an adjuvant therapy, the paclitaxel plus platinum-based combination regimen had similar effects on survival in the EPSPC and OSPC groups.

Abstract
The existing medical literature was searched for epidemiologic and clinical observations that could point to the etiology of primary peritoneal carcinoma and epithelial ovarian cancer (EOC) using MEDLINE, hand searching of the most important gynecologic oncology journals and looking up all relevant cross references. Primary peritoneal carcinoma does not occur in males (only two cases reported in the literature) despite their possessing the same peritoneal surface as females. It is hypothesized that exposure of the peritoneal surface to components of semen (which occurs only in females) is important in the etio-pathogenesis of primary peritoneal carcinoma and the closely related sporadic EOC. The lack of an equivalent malignancy in pleura and pericardium (which have similar embryological derivations as peritoneum but never exposed to semen) in either sex and in tunica vaginalis (which is similar to the epithelial lining of ovary in females) in males lends credence to this hypothesis. Several other observations explained in detail in the paper are consistent with this line of reasoning. Case-control studies in patients of EOC/primary peritoneal carcinoma will clarify this issue. Experimental studies to study the carcinogenic potential of components of the semen on peritoneal surfaces in animal models are also in order.

Abstract
The objective of this study was to compare the immunohistochemical profile and clinical course of primary peritoneal serous carcinoma (PPC) and primary ovarian serous carcinoma (OSC). These entities are virtually indistinguishable morphologically, but their differential molecular and clinical features are incompletely characterized. Twenty-nine cases of high-grade, high-stage PPC and 96 cases of stage matched OSCs were compared. PPC was identified based on the criteria proposed by the Gynecologic Oncology Group. The tumors were staged according to International Federation of Gynecology and Obstetrics criteria for ovarian cancer and graded according to World Health Organization criteria. Expression of Cox-2, CD-34, bcl-2, and p53 was compared in the two tumors and correlated with clinical data including stage, age, race, and overall survival. Although the median survival, using Kaplan-Meier test, of patients with OSC (1060 days, 35.3 months) was longer than those with PPC (708 days, 23.6 months) the difference was not statistically significant. However, Cox-2 expression was correlated with microvessel density in PPC (p=0.026) and OSC cases (p=0.005), and high expression of Cox-2 correlated with lower survival rate in OSC cases (p=0.045) but not in PPC cases (p=0.12). These findings, coupled with the morphologic overlap existing between OSC and PPC, support the view that they represent related pathologic entities.

Abstract
Primary papillary serous carcinoma of the peritoneum is an uncommon primary malignancy of the peritoneum and is histologically indistinguishable from papillary serous carcinoma of the ovary. The diagnosis of primary peritoneal papillary serous carcinoma should be considered in the presence of peritoneal and omental masses in the absence of an ovarian mass. Although it has been extensively documented in the pathological and gynaecological oncology literature, the CT appearance of primary papillary serous carcinoma of the peritoneum has been reported in only 51 cases in five reports. We present four patients with CT findings of pathologically proven primary papillary serous carcinoma of the peritoneum. There were a total of 23 patients with a histopathologically proven diagnosis of primary papillary serous carcinoma of the peritoneum between 1980 and 2002 with CT imaging. However, only four of the 23 patients' CT films were retrieved for retrospective evaluation. The rest of the films were not available as either patients had misplaced the films or patients were deceased.

Abstract
Women from families with multiple cases of breast and ovarian cancer, specifically those who carry cancer-associated mutations of BRCA1 or BRCA2 are at increased life-time risk for peritoneal carcinoma, even after previous surgery to remove the ovaries, fallopian tubes and uterus. Hereditary breast-ovarian cancer (HBOC) syndrome and the associated BRCA1 and BRCA2 mutations are particularly prevalent in women of Jewish lineage, and specific BRCA1 and BRCA2 germline mutations have been linked with peritoneal carcinoma and HBOC syndrome in Jewish populations, especially those of Ashkenazi descent. This review presents the currently available data and looks forward toward further and better understanding of peritoneal carcinoma in women with inherited susceptibility. Over 90% of peritoneal cancer in patients from HBOC syndrome kindreds and associated with BRCA1 and BRCA2 mutations are serous carcinomas, which is equivalent with the proportion of ovarian cancers that are serous carcinomas in similar patients. The best indications are that while many peritoneal carcinomas in genetically susceptible women may arise directly from malignant transformation of the peritoneum, others might represent metastases from primary ovarian or fallopian tube carcinomas. Although the incidence of borderline ovarian tumors may not be increased in HBOC syndrome kindreds and those who carry cancer-associated BRCA1 and BRCA2 mutations, these individuals could be susceptible to malignant transformation of borderline lesions of the ovaries and peritoneum. Moreover, recent reports raise the question of possibly increased risk in Jewish carriers of germline BRCA1 mutations for uterine papillary serous carcinoma, which could be the source of metastasis to the peritoneum in some cases. The penetrance of cancer-associated BRCA1 mutations for ovarian cancer is estimated to be 11%-54%, and for BRCA2 mutations the penetrance for ovarian cancer is 11%-23%. So far, available screening methods appear to be insufficient for early detection of many ovarian cancers. Prophylactic oophorectomy has been found to reduce the risk for ovarian cancer in women from HBOC kindreds and those who carry cancer-associated BRCA1 and BRCA2 mutations, leaving a residual risk for peritoneal carcinomatosis of well less than 5%. Therefore, surgical removal of the ovaries, fallopian tubes and uterus, after child-bearing has been completed and by early in the fifth decade of life, are appropriate prophylactic procedures in women whose genetic susceptibility puts them at increased risk for cancers of mullerian tract origin, including ovarian and fallopian tube carcinomas and possibly serous carcinoma of the uterus. Hysterectomy, as well as salpingo-oophorectomy, removes the gynecologic organs targeted for malignant transformation in genetically susceptible women and simplifies decisions regarding hormone replacement therapy and chemical prophylaxis and treatment of breast cancer. Unless a transabdominal operative approach is otherwise indicated, laparoscopic-assisted transvaginal techniques are well suited for intra-abdominal exploration, cytology, biopsies and prophylactic salpingo-oophorectomy and hysterectomy in women with hereditary susceptibility to gynecologic cancer.

Abstract
The objective of this paper was to characterize expression patterns of biologic markers to distinguish papillary serous peritoneal carcinoma (PPC) from papillary serous ovarian carcinoma (POC). Immunohistochemical analysis of HER-2/neu, p53, bcl-2, and nm23-H1 expression was performed on archival paraffin-embedded tissues. Antigen expression was compared at ovarian and extra-ovarian sites. Thirty-two PPC cases were compared to 18 POC cases. Mean age, stage, grade, and survival outcome were comparable between the two groups. Antigen expression patterns were not significantly different between PPC and POC for the four markers studied. In all cases, nm23-H1 was expressed. Conversely, bcl-2 was expressed at only a single tissue site in three of 32 (9.4%) PPC cases and in one of 18 (5.6%) POC cases. Eleven of 32 (34.4%) PPC cases overexpressed HER-2/neu, vs. four of 18 (22.2%) POC cases. P53 staining results were positive in 23 of 32 (71.9%) PPC and 13 of 18 (72.2%) POC cases. Intrapatient antigen expression was identical at primary and metastatic tumor sites in 50% of the POC and 48.4% of the PPC cases. We conclude that PPC and POC have a comparable immunohistochemical phenotype for these four molecular markers, which is reflected by their similar clinical courses.

Abstract
OBJECTIVES The goals of this study were first, to assess the clinical effectiveness of cisplatin and cyclophosphamide in a phase II study involving a well-defined group of women with extraovarian peritoneal serous papillary carcinoma (EPSPC); and second, to compare these results with those of a group of patients with papillary serous ovarian carcinoma (PSOC) who received identical therapy. METHODS After primary surgery, patients were treated with cisplatin 75 mg/m(2) and cyclophosphamide 750 mg/m(2) every 21 days for six cycles. Patient demographics, tumor characteristics, clinical and surgical response to treatment, progression-free survival, and overall survival were evaluated. These patients were then compared with patients with PSOC who received identical treatment on a separate protocol. RESULTS Women with a diagnosis of tended to be older that those with EPSPC PSOC (median age: 65.8 years vs 60.3 years, P = 0.04). The estimated probability of clinical response (complete and partial) to the treatment regimen for EPSPC was 65% (95% confidence interval [CI]: 41-85%) compared with 59% (95% CI: 47-71%) for women with PSOC. Surgical complete responses were similar (20% vs 19%) in the two patient groups. Additionally, the death rates did not significantly differ between the two groups (hazard ratio: 1.25, 95% CI: 0.834-1.88). CONCLUSION Women with EPSPC and PSOC exhibit a similar probability of response to cisplatin and cyclophosphamide and a similar overall survival. Based on these findings and the fact that results of ovarian cancer trials are frequently extrapolated to patients with EPSPC, it is reasonable to include EPSPC patients in future large-scale treatment trials involving patients with advanced ovarian cancer.

Abstract
BACKGROUND AND OBJECTIVES Our knowledge regarding the pathologic lymphatic spread pattern of primary peritoneal carcinoma (PPC) is limited. The aim of this study was to compare the incidence and the pathologic patterns of pelvic and para-aortic lymph node metastases among women with PPC and those with papillary serous ovarian carcinoma (PSOC). METHODS We conducted a prospective study over the last 4 years among women with FIGO stage III and IV PPC and PSOC who had optimal primary cytoreductive surgery (<1 cm residual). The same surgeon performed pelvic and para-aortic lymphadenectomy on all the patients using a similar technique. The same pathologist reviewed all lymph nodes and recorded nodal involvement with cancer, diameter of the largest nodal tumor, capsular integrity, and pattern of immune response (lymphocyte predominant, germinal cell predominant, unstimulated, or lymphocyte depletion). Both groups were compared in their characteristics, FIGO stage, tumor grade, number of lymph nodes, proportion of lymph nodes with metastases, and the pathologic characteristics of the positive lymph nodes. RESULTS Eleven women had PPC and 27 had PSOC. Patients with PPC were older than those with PSOC (mean age: 63.2 years +/- 11.0 vs. 57.4 +/- 13.4, P = 0.181). There was no difference in FIGO stage or tumor grade between both groups. There was no difference among the mean numbers of pelvic and para-aortic lymph nodes between women with PPC and those with PSOC (10.8 +/- 7.3 vs. 11.0 +/- 6.7 and 3.0 +/- 3.3 vs. 3.4 +/- 2.1, P = 0.768 and 0.706, respectively). The incidences of pelvic, para-aortic, and pelvic and/or para-aortic lymph node metastases were similar among women with PPC and those with PSOC (72.7% vs. 66.6%, P = 0.701, 72.7% vs. 48.1%, P = 0.172, and 72.7% vs. 77.8%, P = 0.736, respectively). Similarly, pelvic and para-aortic nodal tumor size, capsular integrity, and immune response were similar in both groups. The incidence of significant complications related to lymphadenectomy was low among women with PPC and those with PSOC (9.1% vs. 7.4%, respectively). CONCLUSIONS PPC and PSOC exhibit similar pathologic lymphatic spread patterns. Pelvic and para-aortic lymphadenectomy should be considered among women with PPC in whom the tumor could be optimally cytoreduced.

Abstract
AIMS To evaluate the role of mesothelial markers (calretinin, thrombomodulin, cytokeratin 5/6, and CD44H) and carcinoma markers (polyclonal and monoclonal carcinoembryonic antigen, Leu-M1, CA-125 and Ber-EP4) in distinguishing diffuse peritoneal malignant mesothelioma from primary serous papillary adenocarcinoma of the ovary and peritoneum. METHODS AND RESULTS Paraffin-embedded formalin-fixed blocks from 32 diffuse peritoneal mesotheliomas of epithelial subtype (all females), 20 serous papillary ovarian carcinomas and three primary peritoneal serous papillary carcinomas were studied. Calretinin and Ber-EP4 appeared to be the best positive mesothelial and carcinoma marker, respectively. Nuclear calretinin expression was identified in 28 of 32 malignant mesotheliomas with no nuclear immunoreactivity in the cohorts of serous papillary ovarian and peritoneal carcinomas, thus yielding 88% sensitivity and 100% specificity. Ber-EP4 showed 95% sensitivity and 91% specificity for serous papillary ovarian carcinoma. Thrombomodulin, cytokeratin 5/6 and CD44H immunoreactivities were seen in 18 (56%), 17 (53%) and 15 (47%) of peritoneal mesotheliomas, respectively, and in six (30%), five (25%) and five (25%) of the ovarian tumours, respectively. None of the three primary peritoneal serous papillary carcinomas expressed calretinin, thrombomodulin, cytokeratin 5/6 or CD44H. Polyclonal and monoclonal CEA, and Leu-M1 were expressed by two (10%), one (5%) and seven (35%) serous papillary ovarian carcinomas, respectively. None of the serous papillary peritoneal carcinomas expressed polyclonal CEA, monoclonal CEA or Leu-M1. CA-125 was positive in 19 (95%) and two (67%) ovarian and peritoneal carcinomas, respectively, and in eight (25%) peritoneal mesotheliomas. CONCLUSIONS Calretinin and Ber-EP4 are useful discriminant markers in distinguishing peritoneal mesothelioma in women from serous papillary ovarian and peritoneal carcinoma. The other mesothelial markers (thrombomodulin, cytokeratin 5/6, and CD44H) and carcinoma markers (polyclonal and monoclonal CEA, and Leu-M1) yielded a too low sensitivity for practical use.

Abstract
OBJECTIVE Papillary serous carcinoma of the peritoneum (PSCP) coexisting with, or after, endometrial carcinoma (EC) is an extremely rare condition with no documented patient series. The aim of this investigation was to describe our experience in treating five patients diagnosed with PSCP synchronously with EC and two others who developed PSCP metachronously after EC. METHODS In this retrospective study, we reviewed and analyzed the clinical and pathological data of seven patients diagnosed and managed over a 10-year period. The diagnosis of PSCP was mostly based on the inclusionary criteria of the Gynecologic Oncology Group [1]. Disease stages were determined using the FIGO criteria for epithelial ovarian cancer (EOC) and endometrial carcinomas [2]. The treatment for PSCP was similar to that for advanced EOC and immunohistochemical studies were performed using archival material for PSCP and EC in order to determine p53, Bcl-2, HER2, and estrogen and progesterone receptor (ER, PR) status. Germline mutation analyses were performed for the two most common mutations pertaining to BRCA1 and the one most common mutation pertaining to BRCA2 genes only. RESULTS Five patients with PSCP and synchronous EC initially underwent surgical treatment. The remaining two underwent surgery originally for EC and, thereafter, for metachronous PSCP. All seven patients had advanced stages (III or IV) of PSCP and stage I only EC. At the time of analysis, four patients were alive. p53, Bcl-2, ER, and PR were found to have been expressed in various rates in both or one of the neoplasms. However, no HER2 was found to have been expressed, either in PSCP or in EC. All germline mutation analyses were negative. CONCLUSIONS The results obtained in this study show that PSCP can occur either synchronously or metachronously with lower stage EC that is associated with advanced disease stages. We suggest that this clinical form of PSCP with synchronous or metachronous EC is a very aggressive and lethal clinical form and differs markedly from the vast majority of multiple gynecologic neoplasms of the upper genital canal diagnosed in the ovarian-endometrial group, of which EOC are mostly diagnosed as stage I diseases with high-rate cures.

Abstract
BACKGROUND Primary papillary serous carcinoma of the peritoneum is a well-known entity in women. The tumour is derived from the extraovarian mesothelium and the pelvis and lower abdomen mesothelia. The treatment strategies are similar to ovarian serous papillary carcinoma. PATIENTS AND METHODS A case of primary serous papillary carcinoma of the peritoneum in a man is presented. The patient, 53 years old, died 2 months after diagnosis. RESULTS The histologic and immunohistochemical studies of the tumour will be presented. These studies, made during lifetime and at autopsy of the patient, confirm a diagnosis of primary serous papillary carcinoma of the peritoneum. CONCLUSIONS primary serous papillary carcinoma of the peritoneum can occur in men, and should be considered in the differential diagnosis in cases of abdominal carcinomatosis of unknown origin. Treatment options remain to be determined.

Abstract
AIMS The clinicopathological, immunohistochemical and aetiological aspects, with respect to asbestos, of seven primary gonadal mesotheliomas (three intratesticular, four ovarian) are described and compared. These tumours are extremely rare, poorly described and the knowledge of their natural history is very limited. METHODS AND RESULTS The cases were collated from the UK Health and Safety Executive Mesothelioma Register over a 24-year period (1968-91). Primary mesotheliomas of the tunica vaginalis and ovary comprised 0. 09% (10 cases) and 0.03% (three cases) of mesothelioma deaths, respectively. No primary intratesticular (non-tunica vaginalis) malignant mesotheliomas have been described. In this study, we present seven (three intratesticular, four ovarian) primary malignant gonadal mesotheliomas. In both genders the tumours show a similar age distribution (with median onset in the sixth decade), a similar association with asbestos (in approximately 50% cases), a diverse histological spectrum (with predominantly tubulopapillary epithelial subtype tumours) and an immunophenotype that is comparable with malignant pleural and peritoneal mesothelioma. The clinical course appears variable (mean, 26 months; range, 9-50 months). All tumours in the study presented as localized masses and their prognosis appeared more favourable than that of diffuse pleural and peritoneal cases. CONCLUSIONS An awareness of the existence of these rare forms of malignant mesothelioma is important to prevent misdiagnosis. Immunohistochemistry has an important role in confirmation of the diagnosis. The accurate diagnosis of primary gonadal mesothelioma has potentially important medicolegal compensation considerations as a significant proportion of these cases are associated with asbestos.

Abstract
BACKGROUND Primary peritoneal carcinoma is an uncommon disease, characterized by peritoneal carcinomatosis without other identifiable primary tumor. It typically presents resembling ovarian cancer, with abdominal pain and distention and in an advanced stage. We report a unique presentation of this disease. CASE A 76-year-old woman had severe glandular dysplasia on a screening Papanicolaou smear. An ectocervical lesion was biopsied, revealing moderately differentiated adenocarcinoma. Cervical stenosis prevented sampling of the endocervix and endometrium. Colonoscopy and mammography did not reveal malignancy. Total abdominal hysterectomy with bilateral salpingo-oophrectomy was performed. Surgery revealed surface implants on the pelvic organs, with minimal involvement of the ovaries. Histologic examination revealed adenocarcinoma with papillary serous differentiation. Surgical and microscopic findings were consistent with a diagnosis of primary peritoneal carcinoma. CONCLUSION Primary peritoneal carcinoma usually presents in a manner similar to that of ovarian cancer, but atypical presentations also occur. While a Papanicolaou smear suggestive of carcinoma usually represents a primary cervical malignancy, this case serves as a reminder that other metastatic malignancies should be considered.

Abstract
We present the CT findings of three cases of primary papillary serous carcinoma of the peritoneum. All patients presented with massive ascites. CT of the abdomen and pelvis showed omental caking in all patients. The parietal peritoneum of the pelvis showed diffuse enhancement with nodular thickening in all patients. No calcification was noted in the omental and parietal peritoneal masses, although psammoma bodies were present microscopically in one case. The ovaries were normal in size but showed a fine enhancing surface nodularity similar to the pelvic peritoneum. The CT findings of primary papillary serous carcinoma of the peritoneum are nonspecific, but this diagnosis should be considered when peritoneal carcinomatosis is seen on CT with normal-sized ovaries in the absence of other primary malignant neoplasms.

Abstract
OBJECTIVE To determine the pathological, clinical, and therapeutic factors which had prognostic significance in women with extraovarian primary peritoneal carcinoma (EOPPC). METHODS A retrospective, clinicopathologic study was conducted of 75 women diagnosed with EOPPC. Diagnosis and assessment of prognostic pathological factors were based on the Gynecologic Oncology Group (GOG) criteria. Univariate and multivariate analyses were used to assess the following factors for their effect on overall survival: age, parity, presenting symptoms and signs, ascites, CA 125 level, history of oophorectomy, maximum ovarian dimension, histologic type, architectural and nuclear grades, number of mitosis and psammoma bodies, depth of ovarian invasion, estrogen and progesterone receptors (positive, negative), p53 overexpression (present, absent), performance status (GOG criteria), stage (FIGO criteria for ovarian cancer), debulking surgery (optimal versus suboptimal), first-line chemotherapy (platin-based without paclitaxel versus platin/paclitaxel), secondary cytoreduction, and second-line chemotherapy (paclitaxel-based versus no paclitaxel). RESULTS The median overall survival of all patients was 23.5 months (95% CI 18.6, 39.8 months). The 5-year survival was 26.5% (SE 6.7%). p53 overexpression and estrogen and progesterone receptor positivity were demonstrated in 42.4, 50.0, and 6.3%, respectively. In univariate analysis, performance status, primary debulking surgery, stage, and age were significant on overall survival (P < 0.001, <0. 001, 0.004, and 0.012, respectively). In multivariate analysis, only performance status (P < 0.001) and primary debulking surgery (P = 0. 03) were independent prognostic factors. Conclusions. Overall survival in women with EOPPC is affected significantly by performance status and primary debulking surgery as independent variables. To improve survival, efforts should be made to achieve optimal tumor cytoreduction at primary surgery.

Abstract
OBJECTIVE Our objective was to describe the CT characteristics of primary papillary serous carcinoma of the peritoneum. CONCLUSION The presence of peritoneal masses, extensive omental calcification, and the absence of an ovarian mass on CT--particularly in postmenopausal women--is highly suggestive of primary papillary serous carcinoma of the peritoneum and should alert the radiologist to the possibility of this diagnosis.

Abstract
BACKGROUND AND OBJECTIVES The incidence and significance of lymph node involvement in patients with primary peritoneal adenocarcinoma (PPA) are unknown. The aim of the current study is to report on the incidence and significance of clinically or surgically detectable lymphadenopathy in women with PPA. METHODS The study is a retrospective clinical review of patients with the confirmed diagnosis of PPA treated at Roswell Park Cancer Institute between 1982 and 1996. Patients with clinically or surgically detectable lymphadenopathy confirmed on histologic examination to be secondary to metastases from PPA were identified and compared to patients with negative lymph nodes with regard to clinicopathologic characteristics, treatment, response to treatment, and survival. RESULTS Seventy-two patients with PPA were identified. Pelvic and periaortic lymph node biopsies or sampling were performed in 35% of the patients. In 8/72 patients (11%), lymphadenopathy was one of the presenting clinical or surgical findings. The clinicopathologic features, treatment, response to first-line chemotherapy, and estimated median overall survival were not different in patients with or without lymph node involvement (71.4% vs. 69.7%, P = 1.0, and 21.5 vs. 23.5 months, P = 0.14). CONCLUSIONS Lymph node involvement is not an infrequent occurrence in patients with PPA and does not seem to be of adverse prognostic significance.

Abstract
OBJECTIVES The aim of the current study is to evaluate the results of therapy with induction with weekly cisplatin followed by the combination of cisplatin-doxorubicin-cyclophosphamide (PAC) or the combination paclitaxel-cisplatin (TP) as first-line chemotherapy in patients with primary peritoneal adenocarcinoma (PPA). METHODS Between October 1988 and July 1996, 46 patients with PPA were treated with PAC (n = 25) or TP (n = 21) following cytoreductive surgery in two sequential trials. In trial 1, patients received induction with weekly cisplatin (1 mg/kg) x 4 followed by monthly cisplatin (50 mg/m2), cyclophosphamide (750 mg/m2), and doxorubicin (50 mg/m2) for 10 cycles. In trial 2, patients received induction with weekly cisplatin (1 mg/kg) x 4 followed by monthly cisplatin (75 mg/m2) and paclitaxel (135 mg/m2) over 24 hr for 6 cycles. Surgical assessment of response was performed in 15 (60.0%) and 13 (61.9%) patients in the PAC and TP trials, respectively. Estimated survival and progression-free survival distributions were calculated by the method of Kaplan and Meier. Survival curves were compared using the log rank test. RESULTS There were no significant differences between patients in either treatment arm with respect to median age, substage, percentage of patients undergoing optimal cytoreductive surgery, median preoperative CA125 values, performance status, proportion of patients who had second-look procedures, or median cumulative doses of cisplatin. The incidence of nausea and vomiting as well as peripheral neuropathy was significantly higher among patients who received TP (P = 0.005 and 0.022, respectively). The overall response, surgical response, and complete surgical response were not statistically different among patients who received PAC and those who received TP (62.5% versus 70.0%, P = 0.75, 73.3% versus 76.9%, P = 0.1, and 13.3% versus 23.1%, P = 0.64, respectively). Patients who underwent optimal cytoreductive surgery demonstrated higher response than patients whose tumors could not be optimally cytoreduced (76.7% versus 42.9%, P = 0.04). There was no statistically significant difference in overall survival or time to progression/recurrence between the PAC and TP groups (median 21.5 versus 24.0 months, P = 0.68, and 17.3 versus 24.0 months, P = 0.59, respectively). In both treatment groups combined, 18 of 32 patients whose tumors were optimally cytoreduced and 3 of 14 patients whose tumors were suboptimally cytoreduced had surgically verified response. Patients who underwent optimal cytoreductive surgery exhibited longer survival than those who underwent suboptimal cytoreductive surgery (median 29.4 versus 18.6 months, P = 0.008). CONCLUSIONS Both PAC and TP regimens are effective combinations in patients with PPA. The median survival was similar following PAC and TP but the responses and time to recurrence/progression were nonsignificantly better in the paclitaxel combination.

Abstract
Primary papillary serous carcinoma of the peritoneum (PPC) is clinically and histologically similar to advanced stage epithelial ovarian carcinoma. PPC classically presents with widespread intraperitoneal dissemination, superficial invasion, and minimal ovarian involvement. Surgical cytoreduction and combination chemotherapy utilized for patients with epithelial ovarian carcinoma have produced varying results for patients with PPC. These differences in response may be secondary to the stage of disease or due to biological differences in metastatic behavior between these carcinomas. In this study, short-term primary cultures of PPC and epithelial ovarian carcinoma (OVCA) were compared to enable biochemical comparison with respect to components of the metastatic cascade including adhesion, migration, and proteinase activity. These data demonstrated similar properties in adhesive profiles of PPC and OVCA, with preferential adhesion to type I collagen and vitronectin. Matrix-degrading proteinases including matrix metalloproteinases (MMP)-2, MMP-9, and urinary-type plasminogen activator were produced by both cell types. PPC migration was stimulated by multiple extracellular matrix proteins, whereas OVCA cells demonstrated maximal migration on type I collagen coated surfaces. Together our data suggest biochemical similarities between PPC and OVCA with respect to individual components of the metastatic cascade.

Abstract
Primary peritoneal adenocarcinoma is a relatively newly identified disease entity whose clinical behavior is not fully recognized. We report a case of a patient with progressive primary peritoneal adenocarcinoma who developed brain metastases and died shortly afterward. The incidence of central nervous system metastases in 72 patients with documented primary peritoneal adenocarcinoma was 1.4%. The risk factors, clinical behavior, and prognosis of patients with primary peritoneal adenocarcinoma metastatic to the central nervous system seem to be similar to those of patients with epithelial ovarian cancer metastatic to the central nervous system.

Abstract
In the 1960s, a close relationship between heavy exposures to crocidolite asbestos and mesothelioma was established. The debate on the diagnosis of mesothelioma became complicated because of the possibility of litigation. Well differentiated mesothelioma cells are mucicarmine negative but alcian blue and periodic acid-Schiff (PAS) positive, which are removed by hyaluronidase and diastase digestion. By electron microscopy (EM), they show bush-like elongated, slender, and branching microvilli. By immunohistochemistry they express both keratin and vimentin but not carcinoembryonic antigenicity (CEA), B72.3, Ber-EP4, and Leu-M1. In poorly differentiated mesotheliomas, chromosomal and molecular biological alterations are common and complex but these alterations also overlap with that of poorly differentiated tumours of the lung and other organs. A poorly differentiated pleural tumour is most likely metastatic and needs good team work to locate the primary site. The diagnosis of a mesothelioma and asbestosis should be established separately. Future studies will be focused less on the phenotypic differences but more on the broad molecular and multi-phasic mechanisms of carcinogenesis, irrespective of the aetiological agents, in poorly differentiated tumours.

Abstract
Nine cases of malignant mesothelioma (MM) presenting as ovarian masses occurred in female patients aged 16 to 63 (median, 52) years. In most of the cases, the referring pathologist initially misdiagnosed the neoplasm or was uncertain about its nature. In two cases, the tumors were confined to one or both ovaries, representing primary ovarian MMs; only one similar case has been previously reported. In the other cases, widespread peritoneal tumor precluded definite conclusions about the primary or secondary nature of the ovarian involvement. That at least some of the latter were also primary ovarian MMs is suggested by a degree of ovarian enlargement, the striking parenchymal replacement, or both, which are not usually seen in cases of secondary ovarian involvement by peritoneal MMs. The clinical presentation was usually that of abdominal or pelvic pain or abdominal swelling, an adnexal mass on pelvic examination or at laparotomy, or combinations thereof. One tumor was an autopsy finding. There was no history of asbestos exposure in any patient. Eight patients underwent bilateral oophorectomy, usually with hysterectomy and biopsies of extraovarian tumor. Four patients were given chemotherapy and one, radiation therapy. Follow-up in five cases revealed that three patients had died of tumor at postoperative intervals of 8 to 44 months, one was alive with persistent tumor at 18 months, and one was alive with no clinical evidence of tumor at 11 years. The ovaries were replaced by tumors 3 to 15 cm in maximum diameter; seven were bilateral. The neoplastic tissue was typically solid, but small cysts were present in two cases, and one tumor was a unilocular cyst with a solid mural nodule. On microscopic examination, tumor involved both the serosa and the parenchyma of the ovary in seven cases, the serosa only in one case, and the parenchyma only in one case. Seven tumors were exclusively epithelial, with papillary, tubular-glandular, and solid patterns, and two were biphasic. The cells in the epithelial mesotheliomas usually exhibited moderate atypicality and a low mitotic rate. The stroma was typically hyalinized, and in three of the cases with a papillary pattern papillae with hyalinized cores were a striking finding. Psammoma bodies were present in three cases. Histochemical and immunohistochemical stains confirmed the mesothelial nature of the tumor cells. Because of the wide variety of microscopic patterns in MMs, the differential diagnosis of ovarian MM includes a variety of primary and metastatic ovarian tumors as well as other peritoneal mesothelial lesions.

Abstract
The syndrome of adenocarcinoma of unknown primary (ACUP) is a frequent problem in both medical and surgical practice. The prognosis is poor, the median lifespan being 4 months. In general, multiple invasive procedures aimed at determining the primary tumour are not warranted due to the low frequency of detecting a tumour for which adequate treatment exists. In this paper we wish to highlight a subset of female patients presenting with malignant ascites and no evidence of a pelvic mass, who on laparotomy were found to have primary peritoneal papillary serous adenocarcinoma. These tumours must be regarded as a potentially treatable subset of patients with ACUP in view of their frequent response to chemotherapy and relatively good prognosis.

Abstract
OBJECTIVE To describe the clinical features of papillary serous carcinoma of the peritoneum followed by a short review of the literature. METHODS From January 1986 to May 1994, six patients with papillary serous carcinoma of the peritoneum were treated at our institution. Their presenting features, sites of disease at the time of staging laparotomy, subsequent treatment and follow-up were reviewed. RESULTS The mean age was 53.3 years (range 46-59). The most common presenting features were abdominal pain, distention and the presence of ascites. Common sites of disease at the time of laparotomy were the peritoneal and subdiaphragmatic surfaces, omentum, serosa of bowel and superficial involvement of the ovaries. Patients were treated with cytoreductive surgery and platinum-based chemotherapy. CONCLUSION Although experience is scant and more data is needed, for the time being, management for primary peritoneal carcinoma is as for ovarian cancer.

Abstract
BACKGROUND Papillary serous carcinoma of the peritoneum (PSCP) is a primary peritoneal tumor in women that histologically resembles papillary serous carcinoma of the ovary (PSCO). Recognition of PSCP as an entity is controversial, as is the histogenesis, histopathologic differential diagnosis, and treatment. METHODS Ten cases of PSCP retrieved from the pathology files of 4 hospitals in Kyoto and Nara, Japan, were studied clinicopathologically and immunohistochemically. RESULTS Patient ages at presentation ranged from 40 to 74 years (median, 56 years). All patients were Asian (Japanese). None of the patients had a history of asbestos exposure. Most of the patients had abdominal swelling, ascites with positive cytology, and elevated serum CA125. At surgery, omental tumors with dissemination to the abdominal and pelvic peritoneum were found in all patients. The histology was similar to that of Grade 2 to 3 PSCO. Immunohistochemical studies using a panel of monoclonal antibodies against carbohydrates showed that Lewis Y is a good marker, in addition to S-100, placental alkaline phosphatase, CA125, and CD15 for separating PSCP from malignant mesothelioma (MM). With cytoreductive surgery and cisplatin-based combination chemotherapy and in some cases adoptive immunotherapy and radiation, a median survival of 27 months and a 5-year survival rate of 27% were attained. One patient with Grade 3 tumor has survived for more than 6 years after surgery. CONCLUSIONS (1) Papillary serous carcinoma of the peritoneum is a definite clinicopathologic entity; (2) immunohistochemistry is a useful tool for distinguishing PSCP from MM; (3) cytoreductive surgery and cisplatin-based combination chemotherapy with other adjunct therapies such as immunotherapy and radiation may improve patient survival in PSCP.

Abstract
Primary neoplasms of the female peritoneum may be mesothelial or Müllerian in nature. Primary mesotheliomas may be cystic, benign papillary or diffuse malignant. Primary Müllerian tumours of the peritoneum are thought to arise within the secondary Müllerian system: the overwhelming majority are serous in nature and probably develop from pre-existing endosalpingiosis. Primary peritoneal serous tumours of borderline malignancy are identical histologically to the peritoneal 'implants' found in association with ovarian serous tumours of borderline malignancy, whereas primary peritoneal serous adenocarcinomas are histologically identical to ovarian serous adenocarcinomas. The recognition of a primary peritoneal serous neoplasm of borderline malignancy rests on the presence of either normal ovaries, ovaries containing only a fully benign neoplasm or ovaries showing only minimal surface involvement. The diagnosis of a primary peritoneal serous adenocarcinoma is made if the ovaries are of normal size with either no tumour or only minimal surface involvement: in some cases normal ovaries will have previously been prophylactically removed because of a family history of ovarian cancer. The differential diagnosis between a primary serous adenocarcinoma and a diffuse malignant mesothelioma can be difficult and is often not resolved by either electronmicroscopy or immunocytochemistry.

Abstract
BACKGROUND Malignant mesothelioma reportedly shows different epidemiology and pathology in females, and a proportion are believed to arise spontaneously. METHODS One hundred and seventy seven cases of malignant mesothelioma in females were reviewed, examined by histochemistry and immunohistochemistry, assessed for asbestosis and lung fibre burden by transmission electron microscopy with energy dispersive x ray analysis, and compared with 31 female controls. RESULTS Two of one hundred and three cases tested for carcinoembryonic antigen were positive and were excluded from further analysis. Tumour cases showed increased amphibole burdens; in those in whom exposure information was known, 74 (80%) of 93 patients had a history of exposure to asbestos. Seventy two (47%) of 152 patients had lung fibrosis. Tumour site and histological type were little different from those reported in adult males. Mixed type histological pattern, lung fibrosis, and peritoneal site were associated with heavier lung asbestos burdens, but not exclusively. Thirty five (30%) of 117 patients had amphibole burdens of less than 2 x 10(6) fibres/g; the sites affected and the histological pattern of tumours in this group were similar to those in cases with amphibole fibre counts of > or = 2 x 10(6)/g lung. A higher lung amphibole burden than the mean burden in control females was found in 115 (98%) of 117 patients tested. CONCLUSIONS The pathology of malignant mesothelioma appears to be similar in women and in men, and in cases associated and unassociated with asbestos.

Abstract
Primary tumors of the peritoneum are rare. Histological differentiation between papillary mesotheliomas, primary ovarian tumors, borderline tumors of the ovary with peritoneal deposits and primary peritoneal carcinoma may be difficult. The expression of vimentin, keratin, pankeratin, CEA, CA125, CA19-9, S100, B72.3 and BerEP4 was therefore investigated in twelve women with primary malignant peritoneal tumors, twelve women with pleural mesothelioma, eight women with serous ovarian carcinoma and four men with peritoneal mesothelioma. The marker pattern we used was no help in differentiating between metastatic ovarian carcinoma and primary peritoneal carcinomatosis. A combination of the markers S100, B72.3 and BerEP4 helped the distinction between mesotheliomas and the other malignancies. If two or all three markers are detectable, primary peritoneal carcinomatosis or metastatic ovarian carcinoma is the possible diagnosis. If none of the three markers are found, a diagnosis of mesothelioma is highly probable.

Abstract
A patient with peritoneal papillary serous carcinoma involving the colon and omentum is presented. Following palliative right-sided hemicolectomy and partial omentectomy, chemotherapy was given. The patient had a second look operation after 6 months when a pelvic clearance was done and histology revealed some residual tumor in one mesosalpinx. She was well and clinically free of recurrence after a further 6 months. Serum CA125 and CEA levels were measured and CA125 levels remained high throughout.
