ABSTRACT: Scleroderma-like cutaneous lesion as an adverse event from paclitaxel and carboplatin has been reported. No report shows the occurrence of scleroderma-like cutaneous lesions from a single course of carboplatin. The patient is a 67-year-old female, administered paclitaxel and carboplatin as neoadjuvant chemotherapy. Following four courses, scleroderma-like cutaneous lesions were demonstrated. Skin biopsy corresponded to histopathological findings of scleroderma. Immunological investigation shows only antinuclear antibodies are positive. The characteristic Raynaud's phenomenon of scleroderma and hemorrhagic spots on the cuticles were not found. Postoperatively, a single course of carboplatin treatment was given. Scleroderma-like cutaneous lesions re-induced and worsened. This is the first report detailing scleroderma-like cutaneous lesions induced by previously administrated paclitaxel that worsened by carboplatin.

ABSTRACT: The purpose of this study was to evaluate the effectiveness and safety of concurrent chemoradiotherapy using weekly nedaplatin for the treatment of locally advanced squamous cell carcinoma of the uterine cervix. Nedaplatin at 30 mg/m(2) was administered weekly 6 times with a concurrent external beam and intracavity radiotherapy. External beam radiation was delivered with a fraction dose of 2 Gy per day for 5 days a week during a 5-week period and intracavitary brachytherapy, of which the fraction size is 6 Gy to point A, was given once a week for a total of 4 times using a remote after-loading system. Forty-five patients were enrolled in this trial between April 2003 and December 2006. Of the 45 patients, 40 (88.9%) completed the scheduled treatment and were evaluated for efficacy and safety. Of these, 4 were stage Ib2, 12 were stage IIb, 18 were stage IIIb and 6 were stage IVa. The age distribution ranged from 27 to 79 years with a median age of 58. The 40 patients achieved an objective response, 36 (90%) a complete response and 4 (10%) a partial response. At a median follow-up of 29 months (range, 8-52), the 3-year progression-free and overall survival were 58.7% (95% confidence interval, 42-75%) and 78.0% (95% confidence interval, 56-90.0%), respectively. Acute toxicities were transient and rendered non-lethal. Of the 45 patients enrolled for the trial, only 3 (6.7%) had grade 4 leukopenia and neutropenia, respectively. Grade 3 diarrhea and nausea/ vomiting were observed in 2 (4.4%) and 1 (2.2%), respectively. These results indicate that weekly nedaplatin of 30 mg/m(2) with concurrent radiotherapy is an effective and well-tolerated regimen for advanced squamous cell carcinoma of the uterine cervix.

ABSTRACT: We describe a rare case of an Arias-Stella reaction in an adenomyomatous polyp of the endometrium found in the first trimester of pregnancy. A 33-year-old Japanese woman, gravida 1, para 1, presented for an initial prenatal examination at 6-week gestation; ultrasound revealed a myoma-like solid mass in the cervical canal. An abnormal Papanicolaou's smear (highly suspicious of adenocarcinoma) prompted the resection of this pedunculated polyp. Histologically, the musculature located in the center of the polyp was covered by the endometrium; numerous glands within both the endometrium and the musculature exhibited an Arias-Stella reaction. This explains the result of Papanicolaou's smear, because subsequent smears - both intrapartum and postpartum - were negative. To our knowledge, this is the first reported incident of an Arias-Stella reaction in an adenomyomatous polyp. This could be one of the diagnostic pitfalls in Papanicolaou's smears taken during pregnancy.

ABSTRACT: Adenofibroma is a rare benign biphasic neoplasm that is classified into the mixed epithelial and mesenchymal tumor group. We report the case of a 42-year-old woman with adenofibroma of the endometrium protruding into the vagina. Transvaginal ultrasonography revealed the tumor as an intravaginal mass containing multiple cystic components. Magnetic resonance imaging (MRI) showed a heterogeneous high-intensity mass filling the vaginal cavity on T2-weighted imaging, with a low-contrast enhanced septum identified within the mass on gadolinium-enhanced, T1-weighted imaging. Contrast-enhanced computed tomography (CT) showed a heterogeneous low-attenuating multicystic mass filling the vaginal cavity. Although preoperative diagnosis of this rare tumor is very difficult, the combination of MRI, CT, and ultrasonography offers a useful diagnostic tool.

ABSTRACT: Patients with endometrial cancer can present with various complicating illnesses, including obesity, diabetes mellitus, hypertension and advanced aging. These patients are at high risk of severe post-operative complications. Thus, the question of whether or not to perform systemic pelvic and para-aortic lymphadenectomy remains controversial for all patients. It is reported that external iliac lymph nodes are the most commonly involved lymph nodes in endometrial cancer, and para-aortic lymph node (PAN) metastases spread via a route shared by the common iliac lymph nodes. The aim of this study was to evaluate the potential efficacy of omitting PAN dissection when metastasis of the common iliac and external iliac lymph nodes is negative.
Between January 1994 and June 2004, a total of 101 patients at Akita University Hospital who had undergone total hysterectomy and bilateral salpingo-oophorectomy, total pelvic lymphadenectomy and para-aortic lymphadenectomy to the level of the renal vein for endometrial cancer were enrolled in this study.
Eleven patients in all were found to have metastasis for PANs. Among 13 patients with common and/or external iliac positive lymph nodes, 10 showed PAN metastasis. Of the 88 patients with negative lymph nodes, 87 showed no PAN metastasis. Based on these data, common and/or external iliac lymph nodes had 90.9% sensitivity (10/11) and 96.7% specificity (87/90) for detecting PAN metastasis.
Para-aortic lymphadenectomy might be avoided by the negativity of such lymph nodes, thereby minimizing post-operative complications.

ABSTRACT: Some endometrial cancer patients without clinical evidence of extrauterine spread die as a result of recurrence even after curative operation. These recurrences may arise from occult tumor cells that are not detected by conventional methods. The goal of this study was to develop a quantitative method for the detection of disseminated tumor cells (DTCs) in the peripheral blood (PB) and lymph nodes (LNs) of patients with endometrial cancer.
Ninety-eight PB samples from 30 patients and 218 LNs from 14 patients were studied. Real-time quantitative analysis was performed using a LightCycler instrument and a TaqMan probe for cytokeratin 19 (CK19) as a marker gene.
This method resulted in the reproducible quantitation of 10 to 10(6) MCF-7 cells (CK19-expressing breast cancer cell line) per 10(6) peripheral blood nucleated cells. CK19 mRNA expression was detected in 28 PB samples and in 62 LNs. Only three preoperative PB samples and one postoperative PB sample (from four patients) and 33 LNs (from six patients) were PCR-positive. The PCR-positive rate of LNs was higher in patients with pathologically metastatic (path-positive) LNs than in patients with path-negative but PCR-positive LNs. Furthermore, the CK19 mRNA background expression rate was higher in the LNs of path-negative but PCR-positive patients than in LNs of path-negative and PCR-negative patients.
Real-time qRT-PCR with TaqMan probes is a sensitive, specific and rapid method for the detection of DTCs in PB and LNs. Additional studies with larger numbers of patients and adequate follow-up would be of benefit.

ABSTRACT: To evaluate surgical indications for combined partial rectosigmoidectomy in ovarian cancer with direct invasion of the rectum and sigmoid colon or dissemination into the pouch of Douglas.
Subjects comprised 25 patients with ovarian cancer who underwent primary surgery and rectosigmoidectomy between 1990 and 2002 at our hospital. Federation of Obstetrics and Gynecology staging of tumors was II (n = 6), III (n = 17) or IV (n = 2). The histologic type was serous adenocarcinoma (n = 18), clear cell adenocarcinoma (n = 4), and others (n = 3). Bowel resection was performed during primary surgery in 18 patients, and after neoadjuvant chemotherapy (NAC) in seven patients. Cumulative survival rate was compared between NAC and non-NAC groups. Patients were divided into three groups based on extent of surgical resection to compare survival rates: no residual tumor (n = 19); maximum residual tumor diameter <1 cm (n = 5); and maximum residual tumor diameter > or =1 cm (n = 1).
Cumulative 5-year survival was 41.3% for all patients. Cumulative 5-year survival in the 18 patients who underwent bowel resection during primary surgery was 62.2%, compared to 13.9% in the seven patients who underwent bowel resection after NAC. Cumulative 5-year survival based on extent of surgical resection was: no residual tumor, 60.8%; residual <1 cm, 0%; and residual > or =1 cm, 0%. Cumulative 5-year survival for patients with complete tumor resection (no residual tumor), excluding clear cell adenocarcinoma, was 79.5%.
In ovarian cancer with direct invasion of the rectum or sigmoid colon or dissemination into the pouch of Douglas, complete tumor resection with rectosigmoidectomy during primary surgery is associated with good clinical outcomes.

ABSTRACT: Uterine cervical ripening process is an active biochemical process similar in part to inflammatory reaction. In this process, hyaluronan plays important roles including facilitation of tissue hydration, release of matrix metalloproteinases and migration of inflammatory cells. The activities of hyaluronan are mediated by the hyaluronan binding proteins, hyaladherins. In the present study, we investigated the mRNA expression of tumor necrosis factor-alpha stimulated gene-6 (TSG-6), a member of the hyaladherin family, in cultured human uterine fibroblasts and uterine cervical tissues.
We developed one-step RT-PCR method for the quantification of TSG-6 mRNA and quantified the expression of TSG-6 mRNA in cultured human uterine fibroblasts, treated with or not proinflammatory cytokines, and TSG-6 mRNA in uterine cervical tissues.
We clarified that [1] TSG-6 mRNA was expressed constitutively in cultured human uterine cervical fibroblasts, [2] expression of TSG-6 mRNA was upregulated in a dose dependent manner by proinflammatory cytokines, such as IL-1beta and TNF-alpha, which were key mediators in the cervical ripening process, [3] expression of TSG-6 mRNA in uterine cervices during parturition was significantly (P < 0.05) higher than that in a non-pregnant state.
Our results suggest that TSG-6 might participate in the cervical ripening process.

ABSTRACT: In June 1999, a 50-year-old Japanese woman underwent a liver transplant and was started on tacrolimus hydrate. A routine gynecologic examination at that time was unremarkable. In December 2001, the patient was found to suffer from endometrial adenocarcinoma and total abdominal hysterectomy with adnexa was carried out. No significant changes in liver function were observed. However, because fever in the patient of up to 38.5 degrees C continued, the volume of the tacrolimus hydrate was reduced, and then stopped completely. The patient's fever decreased to approximately 36.5 degrees C and she was discharged on the 18th postoperative day. The present case is the first report of endometrial adenocarcinoma in a patient after liver transplantation.

ABSTRACT: The aim of this prospective study was to estimate whether adding human papillomavirus 16 (HPV16) testing to abnormal cervical smears is useful in the prediction of cervical intraepithelial neoplasia 3 (CIN3).
Between October 1994 and May 1996, a total of 207 patients at the Akita University Hospital had abnormal smears. Of these patients, 153 patients with CIN1,2 or atypical squamous cells of undetermined significance (ASCUS) were enrolled in this study and followed until June 2001. At the initial visit, a cervical swab was collected for cytology and for HPV16 testing using nested polymerase chain reaction (PCR). When the HPV16 test was positive, HPV16 testing was performed every 3 to 6 months. We compared the prevalence of progression to CIN3 between the HPV16-positive group (n = 16) and the HPV16-negative group (n = 137). We also investigated the risk of progression to CIN3 associated with persistent HPV16 infection.
At the end of the study period, four patients (25%) in the HPV16-positive group developed CIN3, and all of these patients were found to have persistent HPV16 infection during this period. Only three patients (2.2%) in the HPV16-negative group developed CIN3.
The prevalence of progression to CIN3 in the HPV16-positive group was significantly higher than that in the negative group (p = 0.0023). The odds ratio of progression to CIN3 was 14.9 [95% confidence interval (CI) 2.98-74.4]. In particular, the risk of progression to CIN3 increased with persistent HPV16 infection. Adding HPV16 testing when abnormal cervical smears are detected promises to be useful for predicting CIN3.

ABSTRACT: Annexin V is a Ca(2+)-dependent phospholipid-binding protein belonging to the annexin family whose regulation is currently not well understood. In this study, we utilized anisomycin, a protein synthesis inhibitor that activates MAP kinases (MAPKs), to examine the role of MAPKs in annexin V expression in the MCAS ovarian carcinoma cell line. A one-step real-time TaqMan-based reverse transcriptase-PCR method was developed to quantify annexin V mRNA expression. We found that annexin V was induced 13.3-fold by anisomycin and that this superinduction was attenuated by pretreatment with the MEK inhibitors, U0126 and PD98059, but not with the p38 MAPK inhibitor, SB203580. In addition, immunoblotting showed that anisomycin stimulated the phosphorylation of ERK1/2 as well as p38 MAPK and that the phosphorylations were blocked by the three kinase inhibitors. Taken together, these results suggest that anisomycin superinduces annexin V mRNA expression through the ERK1/2 MAPK pathway, but not through the p38 MAPK pathway.
