Breast cancer followed by corpus cancer: is there a higher risk for aggressive histologic subtypes?

Objective: To analyze corpus cancer patients with a breast cancer history for risk of developing aggressive uterine histologic types.

Methods: Corpus cancer patients with a history of breast cancer were identified from the Surveillance Epidemiology and End Results database from 1988 to 2001. Demographics, clinico-pathologic, and survival data were analyzed using Kaplan-Meier and logistic regression analyses.

Improved survival of Asians with corpus cancer compared with whites: an analysis of underlying factors.

Objective: To compare the clinicopathologic prognosticators and survival of Asians and whites with corpus cancer.

Methods: Demographic, clinicopathologic, and survival data were obtained from the 1992-2001 Surveillance, Epidemiology, and End Results Program. Statistical analyses were performed by Kaplan-Meier methods and Cox proportional hazards model.

Effects of human monoclonal antibody 216 on B-progenitor acute lymphoblastic leukemia in vitro.

Background: Human monoclonal antibody (mAb) 216 is a naturally occurring IgM cytotoxic mAb that binds to a glycosylated epitope on the surface of B-lymphocytes. This study investigated if this mAb could bind and kill acute lymphoblastic leukemia (ALL) B-progenitor lymphoblasts in vitro. ALL cell lines were used to determine if combining mAb 216 with chemotherapeutic drugs would enhance killing and cell lines were used to measure cytotoxicity by mAb 216 with human complement.

Impact of adjuvant therapy on survival of patients with early-stage uterine papillary serous carcinoma.

Purpose: To determine the efficacy of adjuvant therapy in patients with early-stage uterine papillary serous carcinoma.

Methods And Materials: Data were collected on all surgically staged Stage I-II uterine papillary serous carcinoma patients. Statistical analyses were performed using the Kaplan-Meier and Cox proportional hazards regression methods.

Intraoperative radiation therapy in recurrent ovarian cancer.

Purpose: To evaluate disease outcomes and complications in patients with recurrent ovarian cancer treated with cytoreductive surgery and intraoperative radiation therapy (IORT).

Methods And Materials: A retrospective study of 24 consecutive patients with ovarian carcinoma who underwent secondary cytoreduction and intraoperative radiation therapy at our institution between 1994 and 2002 was conducted. After optimal cytoreductive surgery, IORT was delivered with orthovoltage X-rays (200 kVp) using individually sized and beveled cone applications.

A modified technique for insertion of intraperitoneal port for chemotherapy.

The clinical and pharmacological rationale of using intraperitoneal (IP) chemotherapy has been demonstrated in randomized clinical trials. However, IP chemotherapy is often discontinued secondary to catheter-related complications such as blockage, leakage, infection, and access difficulties. An effective method that provides a reliable access to the IP cavity is needed.

B cell lymphoproliferative disorders and VH4-34 gene encoded antibodies.

The VH4-34 represents an unusual Ig heavy chain variable region gene given that it is conserved and overexpressed despite its autoreactivity. Besides RBC 'I/i' recognition, a subset of VH4-34 encoded Igs bind and kill human B-lymphocytes via interaction with a cytoskeletally-associated ligand similar in structure to the cord RBC 'i' antigen. In vivo, secretion of VH4-34 gene encoded antibodies is minimal in healthy individuals.

Differential expression of CD40 and CD95 in ovarian carcinoma.

Purpose: The role of CD95 (Fas) as a mediator of apoptosis has been well documented. CD40 ligation has been recently shown to initiate apoptosis and modulate CD95 mediated apoptosis in normal and some neoplastic tissues. Here we report the expression of CD95 and CD40 in cryopreserved cell suspensions from ovarian cancer associated ascites, fresh primary and recurrent ovarian carcinoma (OVCA) specimens, and ten established ovarian cancer cell lines.

Detection of pelvic lymph node micrometastasis in stage IA2-IB2 cervical cancer by immunohistochemical analysis.

Objectives: The objectives of this study were to (1) determine the incidence of lymph node micrometastasis in cervical cancer by immunohistochemical analysis and (2) determine if the presence of micrometastasis is a poor prognostic feature in early cervical cancer.

Methods: We retrospectively reviewed the medical records of 62 patients who underwent radical hysterectomy and lymphadenectomy for FIGO stage IA2-IB2 cervical cancer at Stanford University Hospital from 1990 to 2000. Forty-nine patients with negative lymph nodes were identified.

Secondary cytoreductive surgery for patients with relapsed epithelial ovarian carcinoma: who benefits?

Background: This study was performed to address patient selection criteria and the role of secondary cytoreductive surgery (SCR) in patients with epithelial ovarian carcinoma (EOC) who had relapsed tumors after a progression-free interval > or = 3 months.

Methods: One hundred seventeen patients with relapsed EOC after a clinical complete remission duration > or = 3 months who underwent SCR were entered on this prospective trial. Survival curves were generated using the Kaplan-Meier method, and statistical comparisons were performed using log-rank tests, logistic stepwise regression analyses, and a Cox stepwise regression model.

Epoxidation of chiral camphor N-enoylpyrazolidinones with methyl(trifluoromethyl)dioxirane and urea hydrogen peroxide/acid anhydride: reversal of stereoselectivity.

Both diastereomeric isomers of epoxides with high optical purity are obtained when camphor N-methacryloylpyrazolidinone (1a) and N-tigloylpyrazolidinone (1b) are treated with a urea hydrogen peroxide/TFAA and methyl(trifluoromethyl)dioxirane, respectively.

Modification of the vertical rectus abdominis musculocutaneous (VRAM) flap for functional reconstruction of complex vulvoperineal defects.

Radical vulvoperineal ablations present challenging reconstructive dilemmas, especially when local metastatic spread requires distal vaginal and anal resection. Despite advances in vaginal salvage and sphincteroplasty, surface recontouring remains elusive because of the necessity to resurface a large, complex area that includes the mons, vulva, and fourchette. We describe a modification of the inferior-based vertical rectus abdominis musculocutaneous (VRAM) flap where the superior portion is split longitudinally to produce "tongue" flaps, which can resurface complex vulvoperineal wounds.

Preoperative CT diagnosis of primary fallopian tube carcinoma in a patient with a history of total abdominal hysterectomy.

Fallopian tube carcinoma is an unusual gynecologic malignancy that is rarely diagnosed preoperatively. We report a case of fallopian tube carcinoma occurring in a patient who had undergone a hysterectomy many years previously, in whom findings on computed tomography and ultrasound were highly suggestive of the diagnosis.

Liposomal doxorubicin for treatment of metastatic chemorefractory vulvar adenocarcinoma.

Background: Primaryadenocarcinoma of the vulva is a rare entity, and for widely metastatic vulvar adenocarcinoma, no effective treatment has been established.

Case: A 65-year-old woman was diagnosed with regionally advanced vulvar adenocarcinoma, with bulky involvement of bilateral groin lymph nodes, and associated extramammary Paget's disease. Initial therapy consisted of multiagent chemotherapy and vulvar and groin irradiation, followed by radical vulvectomy with groin and pelvic lymph node dissection.

VH4-34 encoded antibody in systemic lupus erythematosus: effect of isotype.

Objective: To determine the clinical significance of elevated serum levels of VH4-34 encoded IgM and IgG antibodies with respect to the clinical characteristics of systemic lupus erythematosus (SLE).

Methods: VH4-34 encoded IgM and IgG immunoglobulin was measured in 95 patients with SLE by ELISA using antiidiotype monoclonal antibody (Mab) 9G4. SLE disease activity, severity, and damage were assessed by visual analog scales, Systemic Lupus Activity Measure, Lupus Severity of Disease Index, and Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index.

A new approach to enhancement of bone formation by electrically polarized hydroxyapatite.

An electrical field may affect osteogenesis. Since we found that hydroxyapatite (HA) ceramics may be polarizable, we hypothesized that electrically polarized HA may foster production of new bone in vivo. Both polarized and non-polarized HA ceramics were inserted into the subperiosteum spaces at the parietal bone area of rats.

Effect of 17beta-estradiol or alendronate on the bone densitometry, bone histomorphometry and bone metabolism of ovariectomized rats.

The objective of the present study was to evaluate the effect of 17beta-estradiol or alendronate in preventing bone loss in 3-month-old ovariectomized Wistar rats. One group underwent sham ovariectomy (control, N = 10), and the remaining three underwent double ovariectomy. One ovariectomized group did not receive any treatment (OVX, N = 12).

Susceptibility of B-cell lymphoma to human antibodies encoded by the V4-34 gene.

Our previous studies have shown that mAbs derived from the human V4-34 gene bind and kill human B-lymphocytes via membrane disruption. This study demonstrates the cytotoxicity of two V4-34 encoded mAbs, 216 and Z2D2, towards human B-cell lymphoma. In vitro, 216 and Z2D2 are cytotoxic to a variety of B-cell lymphomas obtained from patient biopsies.

Malignant granular cell tumor of the vulva in a 17-year-old: Case report and literature review.

Granular cell tumors are uncommon soft tissue tumors. Although the majority of these tumors are benign, a rare malignant variant exists which is aggressive, with local recurrence rates up to 70% and 3-year survival rates of less than 50%. We present a case of malignant granular cell tumor of the vulva in a 17-year-old, the sixth such case to be reported at this site.

Primary leiomyosarcoma of the vagina. A case report and literature review.

Primary vaginal leiomyosarcoma is a rare tumor. We report a unique case of a 27-year-old woman with stage I, high-grade primary leiomyosarcoma of the vagina treated with surgical resection and adjuvant radiation therapy. She returned within 6 months with an abdominal-pelvic recurrence and lung metastases.
