1/70. Malignant peritoneal mesothelioma treated by continuous hyperthermic peritoneal perfusion chemotherapy.Malignant mesothelioma of the peritoneum is a rare tumour for which the therapeutic approach has not yet been standardized. The efficacy of the current regimes is limited. Effective locoregional therapy is crucial, since this tumour is most often confined to the peritoneal cavity at the time of the initial diagnosis and remains there for much of its clinical course. If and when haematogenous metastases occur, they rarely contribute to the death of the patient, which is often caused by the overgrowth of the primary tumour and its local complications. A case of diffuse malignant peritoneal mesothelioma treated by cytoreductive surgery and continuous hyperthermic peritoneal perfusion with cisplatin is reported. The patient received systemic combination chemotherapy postoperatively. She is in good condition and free of disease 28 months after her treatment. Continuous hyperthermic peritoneal perfusion chemotherapy has recently been used in patients with secondary peritoneal carcinomatosis from digestive and gynecological malignancies with promising results. It is also possible that the same treatment alone or in combination with systemic chemotherapy may be effective in the treatment of primary peritoneal malignancies, as in the case of diffuse peritoneal mesothelioma.- - - - - - - - - - ranking = 1keywords = disease (Clic here for more details about this article) |
2/70. Chronic administration of single-agent paclitaxel in gynecologic malignancies.OBJECTIVE: There are currently limited published data available on the safety and feasibility of the prolonged administration of paclitaxel. The goal of this study was to review the cumulative toxicity associated with the continuous long-term administration of this agent to women with gynecologic cancers. methods: Eleven patients with gynecologic malignancies of varying histologic subtypes who received >15 consecutive courses of paclitaxel were identified in a retrospective review of individuals treated between 1994 and 1999 in the Gynecologic Oncology Program of the Cleveland Clinic Taussig Cancer Center. The analysis excluded paclitaxel delivered as a component of an initial chemotherapy regimen for the cancer. paclitaxel was administered at doses ranging from 80 to 175 mg/m(2) every 3-4 weeks as a 3-h infusion. RESULTS: In general, the patients included in this report were heavily pretreated and were continued on therapy either as a result of documentation of an objective response or with evidence of stabilization of disease (e.g., physical examination, radiographic evaluation, ca-125 antigen level) and the maintenance of a satisfactory quality of life. In the 11 patients, the median duration of therapy was 20 cycles (range: 16-36 cycles). alopecia was observed in all patients. A single patient experienced grade 3 anemia and grade 4 neutropenia. Of note, there was 1 case of grade 2 and no cases of grade 3 peripheral neuropathy in this population. CONCLUSION: Prolonged delivery of paclitaxel for >15 consecutive cycles can be safely administered to carefully selected patients with persistent or recurrent advanced gynecologic cancers.- - - - - - - - - - ranking = 1keywords = disease (Clic here for more details about this article) |
3/70. Peripheral T/natural killer-cell lymphoma involving the female genital tract: a clinicopathologic study of 5 cases.Malignant lymphoma of the female genital tract (FGT) is rare. In this study, 5 peripheral T/natural killer (NK)-cell lymphomas (PTCLs) involving the FGT are reported. They include 2 from the uterus and 1 each from ovary, uterus and ovary, and vagina, and were detected between 1996 and 2000. One of the 2 ovarian tumors was bilateral. In all cases, the FGT was the initial site of clinical presentation of disease. Age at presentation ranged from 21 to 52 years (median, 36 years). One case was stage I disease, 2 were stage II, and 2 were stage IV. All 5 tumors were positive for CD3epsilon, and 3 harbored the Epstein-Barr virus, although the detailed immunophenotypic profiles varied. Three were diagnosed as nasal type T/NK-cell lymphoma, 1 as anaplastic large-cell lymphoma (anaplastic lymphoma kinase [ALK]-positive), and 1 as unspecified PTCL of cytotoxic phenotype, according to the forthcoming world health organization classification. Four of 5 patients received laparotomy and chemotherapy. Four patients (in stages II and IV) died of disease within 16 months of the initial diagnosis, whereas only 1 patient (in stage I) is alive without disease at 39 months of follow-up. Our experience in this series provided clinically relevant information on diagnosis, treatment, and outcome for extremely rare tumors of the FGT.- - - - - - - - - - ranking = 4keywords = disease (Clic here for more details about this article) |
4/70. Hyalinizing spindle cell tumor with giant rosettes of the broad ligament.BACKGROUND: Hyalinizing spindle cell tumor with giant rosettes (HSTGR) is a rare, recently described tumor that most commonly occurs in the peripheral deep soft tissues. CASE: A 53-year-old woman was operated on because of a mass in the broad ligament which was first noted 17 years previously. The tumor showed typical features of HSTGR. Two years after surgery, the patient is alive with no evidence of disease. CONCLUSIONS: To our knowledge, the present case is the first description of HSTGR occurring in the broad ligament. Despite its bland morphology, HSTGR is a low-grade sarcoma, most probably a variant of low-grade fibromyxoid sarcoma. A wide resection of the tumor and prolonged follow-up are needed because patients may develop late metastases.- - - - - - - - - - ranking = 1keywords = disease (Clic here for more details about this article) |
5/70. liposarcoma complicating pregnancy.BACKGROUND: An adnexal mass in pregnancy is a common occurrence. Malignancy is uncommon and only seven cases of liposarcoma have been reported in association with pregnancy. CASE: We present a case of a pregnant patient who was diagnosed with an adnexal mass detected by ultrasound at 13 weeks gestation. The mass was surgically removed postpartum, when it was found to be a liposarcoma. Postoperatively she received chemotherapy but eventually succumbed to her disease. CONCLUSIONS: liposarcoma is rarely found in association with pregnancy and may follow an aggressive course.- - - - - - - - - - ranking = 1keywords = disease (Clic here for more details about this article) |
6/70. Use of medroxyprogesterone acetate in the treatment of Mullerian adenosarcoma: a case report.BACKGROUND: Mullerianadenosarcoma is a rare pelvic malignancy that most commonly arises from the endometrium. These tumors are relatively insensitive to chemotherapy and radiation and are primarily treated by surgical resection. We report a case of mullerian adenosarcoma arising outside of the uterus from a background of endometriosis treated with a combination of surgical resection and medroxyprogesterone acetate. CASE: A 43-year-old woman with a history of endometriosis was diagnosed with advanced extrauterine mullerian adenosarcoma. After suboptimal tumor dubulking surgery she was treated with medroxyprogesterone acetate. Ten months postoperatively she remains without evidence of disease. CONCLUSION: medroxyprogesterone acetate may be a useful drug in the treatment of advanced mullerian adenosarcoma.- - - - - - - - - - ranking = 1keywords = disease (Clic here for more details about this article) |
7/70. Wolffian duct tumors: case reports and review of the literature.BACKGROUND: female adnexal tumors of probable wolffian origin are a distinctive epithelial neoplasm arising from the remnants of the mesonephric duct. Although generally considered a tumor of low malignant potential, these tumors can recur. Two cases are reported here. CASES: (1) A 38-year-old G(6)P(6) Latin American woman presented with lower abdominal pain and a pelvic mass. She had a history of a total abdominal hysterectomy and bilateral salpingo-oophorectomy with a paratubal nodule found incidentally 3 years prior. The pathologic findings were consistent with a female adnexal tumor of probable wolffian origin. Imaging studies revealed significant metastatic disease throughout her abdomen and pelvis. The recurrence was confirmed at laparotomy and tumor debulking was performed. Four months later the patient suffered a second recurrence and is currently undergoing treatment with systemic therapy. (2) A 71-year-old Caucasian woman who had undergone exploratory laparotomy and tumor reductive surgery for a female adnexal tumor of probable wolffian duct origin was seen for routine evaluation 1 year after her surgery. Her computed tomography scan revealed possible evidence of recurrence. CONCLUSION: Most female adnexal tumors of wolffian origin behave in a benign fashion. However, there is a potential risk of recurrence. Surgical excision by total abdominal hysterectomy and bilateral salpingo-oophorectomy at the time of diagnosis may be the best recommended mode of therapy. The role of adjuvant radiation therapy or chemotherapy remains questionable.- - - - - - - - - - ranking = 1keywords = disease (Clic here for more details about this article) |
8/70. carcinoembryonic antigen: clinical and historical aspects.To further define and determine the usefulness of CEA, 1100 CEA determinations have been made over the past two years at The ohio State University hospitals on patients with a variety of malignant and nonmalignant conditions. Correlation of CEA titers with history and clinical course has yielded interesting results not only in cancers of entodermally derived tissues, for which CEA has become an established adjunct in management, but also in certain other neoplasms and inflammatory states. The current total of 225 preoperative CEA determinations in colorectal carcinomas shows an 81% incidence of elevation, with postoperative titers remaining elevated in patients having only palliative surgery but falling to the negative zone after curative procedures. An excellent correlation exists between CEA levels and grade of tumor (more poorly differentiated tumors showing lower titers). Left-side colon lesions show significantly higher titers than right-side lesions. CEA values have been shown to be elevated in 90% of pancreatic carcinomas studied, in 60% of metastatic breast cancers, and in 35% of other tumors (ovary, head and neck, bladder, kidney, and prostate cancers). CEA levels in 35 ulcerative colitis patients show elevation during exacerbations (51%). During remissions titers fall toward normal, although in 31% still remaining greater than 2.5 ng/ml. In the six colectomies performed, CEA levels all fell into the negative zone postoperatively. Forty percent of adenomatous polyps showed elevated CEA titers (range 2.5-10.0) that dropped following polypectomy to the negative zone. Preoperative and postoperative CEA determinations are important in assessing the effectiveness of surgery. Serial CEA determinations are important in the follow-up period and in evaluation of the other modes of therapy (e.g., chemotherapy). These determinations of tumor antigenicity give the physician added prognostic insight into the behavior of the tumor growth. Rectal examination with guaiac determinations, sigmoidoscopy, cytology, barium enema, and a good clinical evaluation remain the primary tools for detecting colorectal disease. However, in the high-risk patient suspicious of developing cancer, CEA determinations as well as colonoscopy are now being used increasingly and provide additional highly valuable tools in the physician's armamentarium.- - - - - - - - - - ranking = 1keywords = disease (Clic here for more details about this article) |
9/70. colposcopy in the follow-up of women with lower genital tract or perianal carcinoma.colposcopy has gained acceptance in the management of patients with abnormal cytologic smears or visible lesions of the lower genital tract. The well documented potential for the development of multifocal neoplastic disease in these tissues provides the rationale for the suggested use of the colposcope in the follow-up of patients with a previously treated carcinoma of the lower genital or perianal region. The value of colposcopy in such a patient is discussed.- - - - - - - - - - ranking = 1keywords = disease (Clic here for more details about this article) |
10/70. Clinical importance of molecular determinations in gynecologic patients with multiple tumors.BACKGROUND: The prognosis and treatment of patients with multiple tumors may depend on the correlation between tumors: multiple primary tumors, or recurrent tumors, and metastatic disease. The authors investigated whether the detection of molecular aberrations in multiple gynecologic tumors in individual patients provided clinically useful information on the correlation between the tumors. methods: Between 1999 and 2001, molecular analyses were performed on tissue from 15 gynecologic patients, all with multiple tumors. The molecular analyses included loss of heterozygosity determinations at eight dna loci and mutation analyses of p53 exons 5-8 using the single-strand conformation polymorphism method. Previously, it was not possible to use routine diagnostic histopathology to determine accurately the correlation between multiple lesions in patients with gynecologic malignancies, information that may have an impact on clinical decision-making and prognosis. RESULTS: Molecular results were obtained from all tumors from each of the 15 patients. The dna alterations detected provided evidence that two patients had second primary tumors, nine patients had a single tumor with metastases, and four patients had two independent primary tumors as well as metastatic disease. The results provided additional diagnostic information and contributed to clinical decision-making. CONCLUSIONS: The authors demonstrated that, by comparing dna alterations in multiple tumors within an individual patient, evidence about correlations between the tumors can be obtained. These investigations can be performed on routinely processed tissues, and the results may be of clinical importance in helping to determine the management or prognosis of patients with gynecologic malignancies.- - - - - - - - - - ranking = 2keywords = disease (Clic here for more details about this article) |
