AIMTo investigate the effects of tamoxifen on proliferation of human breast cancer Bcap-37 cells and cervical carcinoma HeLa cells and to explore it's possible mechanism.
METHODSThe techniques of cell culture, growth curves, flow cytometry and laser scanning confocal microscope were used.
RESULTSTamoxifen (10(-6) mol/L) shifted the growth curve of Bcap-37 cells downward, and shifted the growth curve of HeLa cells upward. Tamoxifen (10(-8) - 10(-6) mol/L) inhibited the proliferation of Bcap-37 cells in a dose-dependent manner, but stimulated the proliferation of HeLa cells in a dose-dependent manner. Bcap-37 cells appeared apoptosis when treated with tamoxifen (10(-6) mol/L), and the same dose stimulated the proliferation of HeLa cells at GI/S phases. The apoptotic rate of Bcap-37 cells was 97.5%. It blocked G1 phase of HeLa cells from 55.5% to 32.8%, and increased the S phase from 29.0% to 49.4%. Tamoxifen (10(-6) mol/L) also increased the releasing of calcium in Bcap-37 and HeLa cells.
CONCLUSIONTamoxifen can significantly influence the proliferation of breast cancer and cervical carcinoma cells possibly by affecting cell cycle and stimulating the releasing of Ca2+ in the cells.

In 2014, 9 topics were selected as major advances in clinical research for gynecologic oncology: 2 each in cervical and corpus cancer, 4 in ovarian cancer, and 1 in breast cancer. For cervical cancer, several therapeutic agents showed viable antitumor clinical response in recurrent and metastatic disease: bevacizumab, cediranib, and immunotherapies including human papillomavirus (HPV)-tumor infiltrating lymphocytes and Z-100. The HPV test received FDA approval as the primary screening tool of cervical cancer in women aged 25 and older, based on the results of the ATHENA trial, which suggested that the HPV test was a more sensitive and efficient strategy for cervical cancer screening than methods based solely on cytology. For corpus cancers, results of a phase III Gynecologic Oncology Group (GOG) 249 study of early-stage endometrial cancer with high-intermediate risk factors are followed by the controversial topic of uterine power morcellation in minimally invasive gynecologic surgery. Promising results of phase II studies regarding the effectiveness of olaparib in various ovarian cancer settings are summarized. After a brief review of results from a phase III study on pazopanib maintenance therapy in advanced ovarian cancer, 2 outstanding 2014 ASCO presentations cover the topic of using molecular subtypes in predicting response to bevacizumab. A review of the use of opportunistic bilateral salpingectomy as an ovarian cancer preventive strategy in the general population is presented. Two remarkable studies that discussed the effectiveness of adjuvant ovarian suppression in premenopausal early breast cancer have been selected as the last topics covered in this review.

OBJECTIVETo study the clinicopathologic characteristics, prognostic factors, response to chemotherapy, chemotherapy-caused disease-free interval and overall survival of small cell carcinoma of uterine cervix (SCCUC).
METHODSTwelve patients with SCCUC were treated from 1995 to 1999, with their clinic ophathologic data retrospectively analyzed. Their stages were I b(1) 2, I b(2) 4, II a 3, II b 1, III b 1 and IV b1. All 12 samples were assessed through immunohistochemical methods including epithelial cell markers and neuroendocrine cell markers, showing positive results in all. Nine early stage patients underwent radical hysterectomy with pelvic lymphadenectomy. Five of these 9 patients had received neoadjuvant chemotherapy (NCH) once or twice before operation, three patients received adjuvant chemotherapy (ACH) once to six times after operation. Three patients with advanced lesions received concurrent chemotherapy twice to four times.
RESULTS44.4% (4/9) of patients treated by pelvic lymphadenectomy showed positive lymph node metastasis. The average disease free intervals of patients who showed positive or negative pelvic lymph node were 16.1 and 25.7 months, overall survival of 19 and 32 months. The success rate of surgery in the NCH group was 100%, 60% of whom showed chemotherapy response pathologically. They showed overall response rates of 80% (4/5), 20% CR (1/5) and 60% PR (3/5).
CONCLUSIONPoor prognosis of small cell carcinoma of uterine cervix, even the early lesions, is due to its high incidence of pelvic lymph metastasis. The risk factor of this lesion is high sensitivity to chemotherapy, but chemotherapeutic long-term survival should be studied further with more allotted material.

This study analyzes the clinical characteristics of the brain metastasis (BM) of gynecologic cancer based on the type of cancer. In addition, the study examines the factors influencing the survival. Total 61 BM patients of gynecologic cancer were analyzed retrospectively from January 2000 to December 2012 in terms of clinical and radiological characteristics by using medical and radiological records from three university hospitals. There were 19 (31.1%) uterine cancers, 32 (52.5%) ovarian cancers, and 10 (16.4%) cervical cancers. The mean interval to BM was 25.4 months (21.6 months in ovarian cancer, 27.8 months in uterine cancer, and 33.1 months in cervical cancer). The mean survival from BM was 16.7 months (14.1 months in ovarian cancer, 23.3 months in uterine cancer, and 8.8 months in cervical cancer). According to a multivariate analysis of factors influencing survival, type of primary cancer, Karnofsky performance score, status of primary cancer, recursive partitioning analysis class, and treatment modality, particularly combined therapies, were significantly related to the overall survival. These results suggest that, in addition to traditional prognostic factors in BM, multiple treatment methods such as neurosurgery and combined chemoradiotherapy may play an important role in prolonging the survival for BM patients of gynecologic cancer.

OBJECTIVE: We aimed to assess the efficacy of neoadjuvant chemotherapy followed by surgery (NACT+S), and compared the clinical outcome with that of concurrent chemoradiotherapy (CCRT) in patients with International Federation of Gynecology and Obstetrics (FIGO) IB-IIB cervical cancer. METHODS: We reviewed 85 patients with FIGO IB-IIB cervical cancer who received NACT+S between 1989 and 2012, and compared them to 358 control patients who received CCRT. The clinical application of NACT was classified based on the following possible therapeutic benefits: increasing resectability after NACT by reducing tumor size or negative conversion of node metastasis; downstaging adenocarcinoma regarded as relatively radioresistant; and preservation of fertility through limited surgery after NACT. RESULTS: Of 85 patients in the NACT+S group, the pathologic downstaging and complete response rates were 68.2% and 22.6%, respectively. Only two young patients underwent limited surgery for preservation of fertility. Patients of the NACT+S group were younger, less likely to have node metastasis, and demonstrated a higher proportion of FIGO IB cases than those of the CCRT group (p≤0.001). The 5-year locoregional control, progression-free survival, and overall survival rates in the NACT+S group were 89.7%, 75.6%, and 92.1%, respectively, which were not significantly different from the rates of 92.5%, 74%, and 84.9% observed in the CCRT group, respectively (p>0.05). CONCLUSION: NACT+S has no therapeutic advantages over CCRT, the standard treatment. Therefore, NACT+S should be considered only in selected patients through multidisciplinary discussion or clinical trial setting.

OBJECTIVE: Neuroendocrine cervical carcinoma is a rare subtype of cervical cancer. These tumors exhibit an aggressive behavior with early regional lymph node and distant metastases. The purpose of our study was to describe five cases of neuroendocrine cervical-vaginal carcinoma and to discuss the potential of the 2-[18F] fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) scan for the detection of this rare malignancy. MATERIALS AND METHODS: Five cases of cervical-vaginal neuroendocrine tumor were retrospectively collected, during a two year (from September 2009 to August 2011) period in our hospital. The clinical staging distributions were International Federation of Gynecology and Obstetrics (FIGO) stage IB2 (1 of 5), stage IIA (3 of 5) and stage IVA (1 of 5). RESULTS: Two cases (cases 1 and 4) were restaged after 18F-FDG PET/CT scan in the initial staging process. Post-treatment 18F-FDG PET/CT scans, in three patients, revealed positive findings for tumor recurrence or lymph node metastases. Two patients (cases 2 and 3) died of tumor within two years. CONCLUSION: 18F-FDG PET/CT scan is a useful tool in cervical-vaginal neuroendocrine tumor. In its initial staging, the 18F-FDG PET/CT scan may help assess the possible nodal involvement or early hematogeneous spreading. We can also use the 18F-FDG PET/CT to detect local recurrence and to evaluate the treatment response after clinical manipulation.

Cervical cancer is one of the most common cancers in women worldwide. The outcome of patients with metastatic cervical cancer is poor. We reviewed the relevant literature concerning the treatment and diagnosis of metastatic cervical cancer. There are two types of metastasis related to different treatments and survival rates: hematogenous metastasis and lymphatic metastasis. Patients with hematogenous metastasis have a higher risk of death than those with lymphatic metastasis. In terms of diagnosis, fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) and PET-computed tomography are effective tools for the evaluation of distant metastasis. Concurrent chemoradiotherapy and subsequent chemotherapy are well-tolerated and efficient for lymphatic metastasis. As for lung metastasis, chemotherapy and/or surgery are valuable treatments for resistant, recurrent metastatic cervical cancer and chemoradiotherapy may be the optimal choice for stage IVB cervical cancer. Chemotherapy and bone irradiation are promising for bone metastasis. A better survival is achieved with multimodal therapy. Craniotomy or stereotactic radiosurgery is an optimal choice combined with radiotherapy for solitary brain metastases. Chemotherapy and palliative brain radiation may be considered for multiple brain metastases and other organ metastases.
