Bi-dimensional acculturation and social support on perinatal depression in marriage-based immigrant women.

BACKGROUND: Sociocultural factors play critical roles in the mental health of marriage-based immigrant women. However, the effect of bi-dimensional acculturation ("adaptation to host culture" and "maintenance of heritage culture") and social support on perinatal depression across time was unknown among them. OBJECTIVE: To examine the effect of bi-dimensional acculturation and social support on perinatal depression among marriage-based immigrant women in Taiwan. METHODS: This longitudinal study recruited 310 immigrant mothers to complete structured questionnaires during pregnancy and postpartum periods. Depression was assessed using the Edinburgh Postnatal Depression Scale. Bi-dimensional acculturation was measured using the Bi-dimensional Acculturation Scale for Marriage-Based Immigrant Women. Social support was measured by a three-subscale instrument, namely emotional, instrumental, and informational support. RESULTS: Depression scores increased from pregnancy to three months postpartum, and decreased from six to twelve months postpartum. The generalized estimating equation results showed that lower adaptation to host culture, emotional support, and informational support were associated with higher maternal depression scores over time. Maintaining heritage culture has both positive (from pregnancy to three months postpartum) and negative associations (from six to twelve months postpartum) with maternal depression, further, increased emotional support enhanced the protective effect of adaptation to host culture, but decreased the positive effect of maintenance of heritage culture on depression. CONCLUSION: Strategies should be developed to assist perinatal immigrant women to adapt to the host culture, maintain their heritage culture, and resolve potential cultural conflicts to decrease their depression. Respect for immigrant mothers' heritage cultures should be accompanied by increased emotional support.

Pazopanib Maintenance Therapy in East Asian Women With Advanced Epithelial Ovarian Cancer: Results From AGO-OVAR16 and an East Asian Study.

OBJECTIVE: The recent phase 3 trial AGO-OVAR16 demonstrated that pazopanib maintenance improved median progression-free survival in patients with ovarian cancer whose disease did not progress during first-line treatment. However, this improvement was not seen in the subset of East Asian patients. The current analysis evaluated the efficacy and safety of pazopanib maintenance in East Asian patients from AGO-OVAR16 and a separate East Asian study. MATERIALS AND METHODS: East Asian patients from AGO-OVAR16 (n = 209) and the East Asian study (N = 145) were randomized 1:1 to receive pazopanib 800 mg/d or placebo for up to 24 months. The primary end point for each study was progression-free survival by RECIST (Response Evaluation Criteria in Solid Tumors) based on investigator assessment. Clinical and genetics data were analyzed separately by study or pooled according to separate predetermined statistical plans. RESULTS: Pazopanib maintenance had a detrimental effect on median progression-free survival versus placebo in East Asian patients from the combined studies (n = 354; 17.9 vs 21.5 months; hazard ratio, 1.114; 95% confidence interval, 0.818-1.518; P = 0.4928). Pazopanib maintenance showed a disadvantage in overall survival in East Asian patients from AGO-OVAR16 versus placebo (hazard ratio, 1.706; 95% confidence interval, 1.010-2.883; P = 0.0465); overall survival analysis was not performed in the East Asian study because of insufficient event numbers. Pazopanib-treated patients had a significantly higher incidence of grade 3 or higher hypertension (27%) and neutropenia (13%) versus placebo. CONCLUSIONS: The treatment effect of maintenance pazopanib in East Asian patients seemed to differ from that in non-Asian patients. In study-specific and pooled analyses, none of the potential factors analyzed could satisfactorily explain the different efficacy results of pazopanib in East Asian patients.

Difference in Practice Patterns in the Management of Endometrial Cancer: A Survey of the Members of 4 East Asian Gynecologic Oncology Groups.

OBJECTIVE: The aim of this article was to identify current practice patterns of care in the surgical and adjuvant management of endometrial cancer in East Asia (Korea, Japan, China, and Taiwan) METHODS: A validated 20-item questionnaire on surgical and adjuvant procedures for endometrial cancer was sent to active members of the Gynecologic Oncology Group from 4 East Asian countries. Data were collected using an Internet survey database. RESULTS: A total of 376 members from Korea (n = 108), Japan (n = 140), China (n = 51), and Taiwan (n = 77) responded to the survey. With respect to early-stage endometrial cancer, laparotomy (57.7%) was the most preferred mode of surgery in Japan, whereas laparoscopy was the most common in the remaining 3 countries. For patients with presumed stage IA/G1 disease, approximately 65% of respondents favored systematic lymphadenectomy. For patients with presumed stage IB disease, most respondents stated that systematic lymphadenectomy should be performed (92.6% for stage IBG1, 95.8% for stage IBG3). Meanwhile, the extents of lymphadenectomy differed among countries (P < 0.001). Considerable agreement was noted between countries regarding indications for adjuvant therapy for stage IIIA or IIIC1 disease, whereas the preferred options for adjuvant therapy varied according to country (P < 0.001). Specifically, chemotherapy was the most common selection option in Japan, whereas concurrent chemoradiotherapy was preferred in the other countries. CONCLUSIONS: Considerable agreement was identified with respect to the necessity for lymphadenectomy for surgical staging and the indications for adjuvant therapy. However, extents of surgery and preferred adjuvant treatment options for endometrial cancer varied widely between countries.

Impact of management on the prognosis of pure uterine papillary serous cancer - a Taiwanese Gynecologic Oncology Group (TGOG) study.

OBJECTIVE: To investigate the clinical and pathological characteristics and the management of uterine papillary serous carcinoma (UPSC) in relation to patients' outcomes. METHODS: Clinicopathological data and the management of patients treated between 1991 and 2010 at 11 member hospitals of the Taiwanese Gynecologic Oncology Group (TGOG) were retrospectively reviewed. The Kaplan-Meier method was used to generate survival curves, and factors predictive of outcome were compared using the log-rank test and Cox regression analysis. RESULTS: A total of 119 pure UPSC patients were recruited. Stages I, II, III, and IV were identified in 34.5%, 2.5%, 36.1%, and 26.9% of the patients, respectively. The recurrence rate was 20.5% in FIGO stage I/II disease and 55.2% in FIGO stage III/IV disease. The 5-year overall survival rates for the patients with stage I, II, III, and IV disease were 92.0%, 66.7%, 34.2%, and 17.3%, respectively. Multivariate analysis showed that tumor stage (stage III/IV hazard ratio [HR] 8.65, 95% confidence interval [CI] 3.00-24.9) and optimal cytoreduction (HR 0.40, 95% CI 0.22-0.73) independently influenced the overall survival rate of UPSC patients. In addition, optimal cytoreduction (HR 0.36, 95% CI 0.17-0.78) and the combination of chemotherapy and radiation (HR 0.11, 95% CI 0.04-0.37) improved the overall survival of the advanced stage (FIGO stage III/IV) UPSC patients. CONCLUSIONS: UPSC represents an aggressive subtype of endometrial cancer commonly accompanied by extra-uterine disease. Comprehensive surgical staging with cytoreductive surgery is mandatory and beneficial for UPSC patients. Systemic chemotherapy combined with radiation should be considered as an adjuvant therapy for advanced stage UPSC patients.

Primary treatment and prognostic factors of carcinosarcoma of the ovary, fallopian tube, and peritoneum: a Taiwanese Gynecologic Oncology Group Study.

OBJECTIVE: This study aimed to determine the clinical prognostic factors involved in carcinosarcoma of the ovary, fallopian tube, and peritoneum. MATERIALS AND METHODS: This retrospective study was undertaken by the Taiwanese Gynecologic Oncology Group. The retrieved clinical data included demographic characteristics, medical disease, tumor status, extent of surgery, and adjuvant chemotherapy. RESULTS: In total, 63 patients with carcinosarcoma of the ovary, fallopian tube, and peritoneum were identified. Sixty-one patients with complete data were enrolled for further data analysis. The mean follow-up period was 1.0 year, and the mean overall survival was 15.4 months. By log-rank tests, age, menopausal status, parity, hypertension, diabetes, primary tumor size, para-aortic lymph node metastasis, pretreatment CA-125, preceding diagnostic surgery, hysterectomy, lymphadenectomy, other surgeries, and paclitaxel use were not predictive of overall survival.Omentectomy, no gross residual implants after surgery, platinum treatment, and no pelvic lymph node metastasis had a trend toward better survival. Early diagnosis at stage I and cisplatin/ifosfamide regimen were significant associated with a better overall survival in log-rank and simple Cox regression tests. Bilateral ovarian tumors and metastatic tumors larger than 2 cm were significantly associated with a poorer overall survival. CONCLUSIONS: Early diagnosis at stage I, unilateral ovarian tumor, metastatic tumors less than 2 cm, and cisplatin/ifosfamide regimen were predictive of a better survival.Omentectomy and complete debulking surgery also showed a trend toward better survival. Thus, these treatment strategies should be applied in patients with carcinosarcoma of the ovary, fallopian tube, and peritoneum.

Abnormal p53 expression is associated with poor outcomes in grade I or II, stage I, endometrioid carcinoma: a retrospective single-institute study.

OBJECTIVE: The Cancer Genome Atlas study revealed an association between copy-number high (p53 abnormal) genetic mutation and poor prognosis in endometrial cancer in 2013. This retrospective study investigated outcomes in patients with abnormal p53 expression and stage I, low-grade endometrial endometrioid carcinoma (EEC). METHODS: We enrolled women with stage I, grade 1 or 2 EEC who received comprehensive staging and adjuvant therapy between January 2019 and December 2022 at MacKay Memorial Hospital, Taipei, Taiwan. Pathologists interpreted immunohistochemistry stains of cancerous tissues to detect p53 mutation. We compared recurrence, survival, progression-free survival, and overall survival between p53 abnormal and p53 normal groups. RESULTS: Of the 115 patients included, 26 had pathologically confirmed abnormal p53 expression. Of these 26 patients, five (19.2%) experienced recurrence, and two died due to disease progression. By contrast, no patients in the normal p53 group experienced disease recurrence or died due to disease progression. Significant intergroup differences were discovered in recurrent disease status (19.4% vs. 0%, p<0.001), mortality (7.7% vs. 0%, p<0.001), and progression-free survival (p<0.001). The overall survival (p=0.055) also showed powerful worse trend. CONCLUSION: For patients with stage I, low-grade EEC, abnormal p53 expression may be used as an indicator of poor prognosis. Therefore, we suggest considering aggressive adjuvant therapies for these patients.

A structural model of the influence of immigrant mothers' depressive symptoms and home environment on their children's early developmental outcomes in Taiwan.

In this cross-sectional study of 61 immigrant mothers and their 6- to 24-month-old children in Taiwan, we examined the structure of relationships among maternal depressive symptoms, quality of the child-rearing home environment, and child development using a partial least squares approach. Maternal depressive symptoms as measured by the Edinburgh Postnatal Depression Scale had a direct and negative effect on the quality of the home environment as measured by the IT-HOME, which in turn had a direct and positive effect on child development as measured by the Comprehensive Developmental Inventory for Infants and Toddlers. Maternal depressive symptoms did not directly affect child development, suggesting that the quality of the home environment mediated the relationship between maternal depressive symptoms and child development.

Origami Box Folding Exercise: A laparoscopic box simulation training and assessment method in facilitating laparoscopic psychomotor skills with minimal preparation.

OBJECTIVE: Laparoscopic box simulation training is widely recognized as an assessment tool to facilitate psychomotor skills especially for novice surgeons. However, current commercialized training modules including pegs, gauze, clips, pins etc. are generally costly and relatively inaccessible. We introduce a simple and pioneer surgical training drill, the Origami Box Folding Exercise (OBFE), based on the validated evaluating system of objective structured assessment of technical skills (OSATS) constructed with the scoring system of procedure-specific checklist (PSC) and global rating scale (GRS). MATERIALS AND METHODS: Face and content validation of the OBFE and OSATS are evaluated by five endoscopic experts from two medical centers in Taiwan. This is a prospective observational study analyzing the pre-test/post-test result of OBFE from 37 participants in two individual workshops as training and evaluating method for laparoscopic psychomotor skills. Both the pre and post tests are video recorded with a time limit of 5 min graded by two independent evaluators based on the OSATS scoring system. RESULTS: The reliability of PSC, GRS, and intergroup value between PSC and GRS were 0.923, 0.926 and 0.933, respectively. Inter-rater reliability of PSC, GRS, and both were 0.985, 0.932 and 0.977, respectively. Construct validity of PSC and GRS were statistically significant, with p-value 0.006 and 0.001, respectively. CONCLUSION: OBFE enhances laparoscopic psychomotor skills with requirement of a single piece of paper. The associated OSATS tool for a 5-min OBFE test was validated. OBFE training is an efficient training and assessment system to promote psychomotor skills in laparoscopic box simulation drill which requires simple and economical preparation.

A long-term follow-up study of 176 cases with adult-type ovarian granulosa cell tumors.

OBJECTIVE: Because of rarity, indolent clinical course, and of most importance, small sample size studies of previous ovarian granulosa cell tumors (GCTs), this study was conducted to report the clinical characteristics and long-term outcomes of 176 pathologically confirmed GCTs. METHODS: Between 1984 and 2010, we retrospectively evaluated 176 patients from multiple medical centers in Taiwan. RESULTS: The mean age at the diagnosis was 46 years and nearly half of the patients (45.7%) were in their fourth or fifth decades of life. The most common symptoms included abdominal pain (28.5%), followed by irregular menstruation (16.7%). The mean tumor size was 10.4 cm. The stage distribution at diagnosis was stage I in 77.8% of patients, stage II in 5.1%, stages III-V in 6.1%, and unknown in 11% of patients. The median follow-up period was 60.7 months. The recurrence rate was 21%. The overall 5- and 10-year survival rates were 96.5% and 94.1%, respectively. In univariate analysis, initial stage, presence of residual tumor after initial surgery, need for adjuvant chemotherapy, and tumor size were associated with disease recurrence. In the multivariate analysis, only the presence of residual tumor after initial surgery and tumor size were significantly associated with recurrence. CONCLUSIONS: The outcomes of patients with GCTs were good, with nearly to 95% of patients surviving 5 and 10 years. The prognosis was related to initial stage, presence of residual tumor after initial surgery, and tumor size (>13.5 cm). Different surgical methods and/or adjuvant therapy appear not to affect the outcome.

Asian perspective on debulking surgery for advanced ovarian cancer: An E-survey.

PURPOSE: We performed an E-survey to evaluate the practice patterns in debulking surgery for advanced ovarian cancer in Asia. METHODS: We designed a questionnaire, including 50 questions related to debulking surgery for advanced ovarian cancer. The questionnaire was sent to Gynecologic Oncologic Groups in Asia from December 2016 to February 2017. RESULTS: A total of 253 gynecologic oncologists from Japan (58.9%), the Republic of Korea (19%), Taiwan (12.6%), and the other counties including China (7.5%), Malaysia (0.8%), Indonesia (0.8%), and Thailand (0.4%) participated in this E-survey. The median number of debulking surgeries per year was 20, and 46.8% of the respondents preferred <1 cm as the criterion for optimal debulking surgery (ODS). The most common barrier and surgical finding precluding ODS were performance status (74.3%) and disease involving the porta hepatis (71.5%). Moreover, 63.2% had a fellowship program, and only 15% or less had opportunities to receive additional training courses in general, thoracic, or urologic surgery. The median percentage of patients receiving neoadjuvant chemotherapy (NAC) was 30%, and the achieved rate of ODS in primary debulking surgery (PDS) and interval debulking surgery (IDS) was 65% and 80%, respectively. Most of the respondents required three to 6 h for PDS (48.6%) and IDS (58.9%). Moreover, more than 50% depended on ultra-radical surgery conducted by specialists. CONCLUSIONS: The ODS criteria are relatively lenient with a preference for NAC in 30% of the respondents in Asia. This trend might be associated with the dependence on aggressive surgery performed by specialists.

Ovarian borderline mucinous tumor with stromal microinvasion and hemangiomatous mural nodules.

A 39-year-old female presented with abdominal distension. A right adnexal mass was found on physical examination, which was shown to be cystic on ultrasound. An exploratory laparotomy revealed a right ovarian mass, which was removed and a staging procedure was performed. Histologically, the mass was a borderline ovarian tumor with stromal microinvasion and hemangiomatous mural nodules.

Comparison in purity and antitumor effect of brand and generic paclitaxel against human ovarian cancer cells by an in vitro experimental model.

CONTEXT: The purity and the therapeutic effectiveness of the generic paclitaxel have not yet been examined and compared to the original brand form. OBJECTIVE: This study aimed to compare the in vitro purity and biological effects of original brand form (Taxol) and a generic drug of paclitaxel. MATERIALS AND METHODS: Purity was determined by high-performance liquid chromatography analysis, cell viability by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide assay, cell proliferation by clonogenic assay, morphology by Liu's staining, and cell cycle distribution by DNA histogram. RESULTS: Taxol and generic paclitaxel shared similar high-performance liquid chromatography profiles with a major peak at the same retention time and ultraviolet spectrum. Generic paclitaxel inhibited the cell viability to an extent greater than Taxol. By assessing the IC(50), generic paclitaxel also exhibited a greater inhibitory activity on clonogenicity of human ovarian adenocarcinoma SKOV-3 cells. Although both generic paclitaxel and Taxol arrested SKOV-3 and ES-2 cells at G2/M phase with concurrent development of hypoploid and polyploid cells, Taxol treatment exhibited markedly less extent of these changes. Observation of cellular morphology revealed a greater amount of mitotic catastrophe-like and apoptotic cells in generic paclitaxel-treated cells than Taxol-treated cells. DISCUSSION AND CONCLUSION: The results suggest that generic paclitaxel may possess a greater cell death inducing capacity and clonogenicity inhibitory activity against ovarian cancer cells than the original brand Taxol of the same purity. We conclude that this experimental model for assessing the difference between generic and brand name drugs might be considered as a reference while determining their interchangeability and could be easily established in a hospital-based laboratory.

Effect of Chemotherapy, Laparoscopy, and Cytology on Stage IC Ovarian Clear Cell Carcinoma: A Long-Term, Single-Center Study.

Ovarian clear cell carcinoma (OCCC) is the second common histology of epithelial ovarian cancer in Taiwan. Stage IC is common, especially during minimally invasive surgery. Adjuvant chemotherapy in stage IC OCCC is unavoidable, and paclitaxel-based chemotherapy in Taiwan is self-paid. However, surgical spillage from minimally invasive surgery as a cause of unfavorable prognosis is still uncertain. The information of patients with stage IC OCCC, corresponding to a period of January 1995 to December 2016, was retrospectively collected following a chart and pathology review. Data regarding surgical methods, cytology status, regimens of adjuvant chemotherapy, survivorship, progression-free survival (PFS), and overall survival (OS) period were analyzed. In total, 88 patients were analyzed, and 64 and 24 patients were treated with paclitaxel- and nonpaclitaxel-based chemotherapy, respectively. Recurrence was identical between the two groups: PFS (47.5 ± 41.36 versus 54.0 ± 53.9 months, p = 0.157) and OS (53.5 ± 38.14 versus 79.0 ± 49.42 months, p = 0.070). Of the 88 patients, 12 had undergone laparoscopy for histological confirmation before complete open staging surgery; however, their PFS (49.5 ± 46.84 versus 49.0 ± 35.55 months, p = 0.719) and OS (56.5 ± 43.4 versus 51.0 ± 32.77 months, p = 0.600) were still comparable. Cytology results were only available for 51 patients, and positive washing cytology results seemed to worsen PFS (p = 0.026) but not OS (p = 0.446). In conclusion, adjuvant nonpaclitaxel chemotherapy and laparoscopic tumor spillage before the staging operation did not worsen the outcome in stage IC OCCC. Positive washing cytology has a negative effect on PFS but not on OS.

Outcomes in Advanced Stage Epithelial Ovarian, Fallopian Tubal, and Peritoneal Cancer after Primary Surgery and Adjuvant Chemotherapies: A Single-Institute Real-World Experience.

Debulking surgery followed by systemic chemotherapy-including three-weekly intravenous paclitaxel and carboplatin (GOG-158)-is the cornerstone for advanced epithelial ovarian, fallopian tubal, and peritoneal cancer (EOC) treatment. In this scenario, Federation of Gynecology and Obstetrics (FIGO) stage, cell types, completeness of surgery, lymph nodes (LN) status, adjuvant chemotherapy regimens, survival status, progression-free survival (PFS), and overall survival (OS) of 192 patients diagnosed as having stage IIIA1-IVB EOC over January 2008-December 2017 were analyzed retrospectively. Of them, 100 (52.1%) patients had been debulked optimally. Of all cases, 64.1% and 10.9% demonstrated serous and clear-cell carcinoma. Moreover, the FIGO stage, surgery completeness, and LN status affected recurrence/persistence and mortality (all p < 0.001). Clear cell carcinoma led to shorter survival than serous carcinoma (p = 0.002). Adjuvant chemotherapy regimens were divided into five main groups according to previous clinical trials. However, choice of chemotherapy failed to demonstrate significant differences in patient outcomes. Similar results were found in the sub-analysis of optimally debulked cases, except that intraperitoneal chemotherapy could reduce mortality risk when compared with GOG-158 (p = 0.042). Notably, retroperitoneal LN dissection in all cases or optimally debulked cases reduced risks of recurrence/persistence and mortality, and prolonged PFS and OS significantly (all p < 0.05). Without optimal debulking, LN dissection led to little improvement in outcomes. Various modified chemotherapy regimens did not prolong PFS and OS or reduce recurrence/persistence and mortality risks. LN dissection is strongly recommended to improve the completeness of surgery and patient outcome. Clear cell type has a poorer outcome than serous type, which requires more aggressive treatment and follow-up.

Oxaliplatin regulates DNA repair responding to ionizing radiation and enhances radiosensitivity of human cervical cancer cells.

Concurrent chemoradiotherapy is a standard treatment of locally advanced cervical carcinoma. The most widely used drug for chemoirradiation is cisplatin. However, its toxicity and drug resistance remain major concerns in clinical practice. This study was designed to evaluate the effect of oxaliplatin, another platinum compound, on enhancing radiosensitivity in cervical cancer cell lines. Human HeLa and SiHa cells were used. Cell survival after irradiation with or without oxaliplatin pretreatment was assessed by performing colony-formation assays. Sensitizer enhancement ratios were calculated using a linear quadratic model. Cell morphology was observed after staining with Wright dye. To evaluate the machinery to repair DNA damage, cellular protein was subjected to Western blotting to assess the expression of damage-related molecules. Nontoxic doses of oxaliplatin were 5 and 10 micromol/L for HeLa and SiHa cells, respectively. Pretreatment with oxaliplatin markedly decreased, with a greater extent than cisplatin, the survival of irradiated HeLa cells. Maximal sensitizer enhancement ratios of oxaliplatin at 37% survival were 3.4 for HeLa cells and 4.8 for SiHa cells. Oxaliplatin pretreatment enhanced the cell cycle arrest in the G2/M phase and the radiation-induced mitotic catastrophe. Oxaliplatin modulated radiation-induced DNA double-strand breaks, as indicated by delayed abrogation of gamma-H2AX, attenuation of radiation-induced phosphorylation of ataxia telangiectasia-mutated kinase and checkpoint kinase 2. In conclusion, oxaliplatin sensitized human HeLa and SiHa cells to ionizing radiation. This effect may involve modulation of ataxia telangiectasia-mutated kinase and checkpoint kinase 2 activation during DNA damage repair.

Treatment of gestational trophoblastic neoplasia according to the FIGO 2000 staging and scoring system: a 20 years' experience.

OBJECTIVE: To reassess the efficacy of the Federation of Gynecology and Obstetrics (FIGO) 2000 staging and risk factor scoring system in comparison to the original World Health Organization (WHO) prognostic scoring system (1983) in a single-institute setting. DESIGN: Retrospective review of the medical records of 89 patients with gestational trophoblastic neoplasia. SETTING: Mackay Memorial Hospital, Taipei, a regional referral center for northern Taiwan, over a 20-year period. METHODS: All selected patients were classified retrospectively by the original WHO prognostic scoring system (1983) and the FIGO 2000 system. MAIN OUTCOME MEASURE: Efficacy as the correlation of risk categorization by percentage of patients between the original WHO scoring system (1983) and the FIGO 2000 system. RESULTS: The correlation was 97%. Only two patients were classified as middle risk group in the original WHO system (1983), but as high-risk group by the FIGO 2000 system. CONCLUSION: There was good correlation between the original WHO (1983) and FIGO 2000 systems. Treatment outcomes by FIGO 2000 system were somewhat better than by the original WHO classification.

Human papillomavirus type and clinical manifestation in seven cases of large-cell neuroendocrine cervical carcinoma.

Large-cell neuroendocrine carcinoma (LCNEC) of the uterine cervix is a very rare malignancy. We aimed to investigate the role of human papillomavirus (HPV) on the survival of patients, and its correlation with clinical parameters of HPV status or survival outcomes. Only seven cases of LCNEC were retrospectively collected among 8018 (0.087%) invasive cervical carcinomas from the cancer registry systems at Mackay Memorial Hospital and Veterans General Hospital over a period of 17 years. The median survival time was 17.2 months, including only one long-term survivor (> 5 years). The 2 year and 5-year survival rates after diagnosis were 42% and 30%, respectively. The results indicated that the majority of LCNEC cases were dominated by high-risk HPV-18. No clinical parameters appeared to be associated with HPV-18 or survival outcomes of LCNEC patients. Pelvic lymph node metastasis positivity could also be considered as a prognostic factor for this disease.

Chinese Version of the Assessment of Survivor Concerns Scale for Gynecological Cancer Survivors: A Psychometric Study in Taiwan.

BACKGROUND: Most gynecological cancer survivors outlive the acute stage, and many reach permanent survival. However, the fear of cancer recurrence (FCR) is stressful and affects quality of life. PURPOSE: This study was designed to validate a Chinese version of the Assessment of Survivor Concerns (ASC) questionnaire in terms of its ability to assess FCR in gynecological cancer survivors. METHODS: A two-stage study procedure was employed. The first stage involved the translation of the ASC questionnaire from English into Chinese using the methods proposed by Guillemin, which include translation, back-translation, consensus meetings, and a trial of potential users. In the second stage, a pilot study was completed with 37 gynecological cancer survivors followed by a psychometric property study with 287 gynecological cancer survivors. Construct validity was determined using confirmatory factor analysis (CFA) with structural equation modeling. Convergent validity was determined using composite reliability and the average variance extracted values of the ASC model. Discriminant validity was determined by comparing the model fitness of the ASC model against the model fitness of a one-construct model. Concurrent criterion validity was assessed using the European Organization for Research and Treatment of Cancer's Quality-of-Life Questionnaire Core 30 as the auxiliary instrument. Reliability was determined by measuring the internal consistency reliability using Cronbach's α in addition to the 3-week test-retest reliability with a 95% confidence interval of the intraclass correlation coefficient. RESULTS: The process of translation and back-translation was performed to ensure the conceptual equivalence of the Chinese version with the original ASC questionnaire. For CFA, the fit indices of the ASC model (χ = 9.87, p > .05; root mean square error of approximation = .03. comparative fit index = 1, nonnormed fit index = 1) indicated appropriate model fitness. For convergent validity, the composite reliability and average variance extracted values of the ASC model were satisfactory. For discriminant validity, the model fitness of the ASC model was significantly improved over the one-construct model. For concurrent criterion validity, the ASC scores correlated negatively with the scores of the global quality of life and the five functions (physical, role, cognition, emotions, and social) of the European Organization for Research and Treatment of Cancer's Quality-of-Life Questionnaire Core 30, as hypothesized. For reliability, the Cronbach's α and the 95% confidence interval of intraclass correlation coefficient for the ASC model were .91 and [.18, .68], respectively. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The Chinese version of the ASC questionnaire is a valid and reliable instrument that is suitable for assessing FCR in gynecological cancer survivors in clinical and research settings.

Human papillomavirus typing with a polymerase chain reaction-based genotyping array compared with type-specific PCR.

BACKGROUND: Type-specific persistence of human papillomavirus (HPV) infection can cause invasive cervical cancer. OBJECTIVES: To evaluate the efficacy of HPV detection and typing with a general polymerase chain reaction (PCR)-based genotyping array and to compare it with a type-specific PCR assay. STUDY DESIGN: Four hundred and thirty-three cervical samples were tested with a modified MY11/GP6+ PCR-based reverse-blot assay (EasyChip HPV Blot; King Car, Taiwan [hereafter HPV Blot]) and with 20 genotypes of L1-type-specific PCR (HPV-6, -11, -16, -18, -31, -33, -35, -39, -45, -51, -52, -53, -56, -58, -59, -62, -66, -68, -70, and -71 [CP8061]). RESULTS: The concordance of the two tests in determining HPV positivity was 96.8% (419/433), with a Cohen's kappa=0.93 (95% CI: 0.90-0.97) and McNemar's test of P=1.0, which indicates excellent agreement. The overall concordance of the two tests in the identification of type-specific HPV was 91.0% (394/433). Sensitivity (90-100%), specificity (99.2-100%), and accuracy (98.6-100%) rates of HPV Blot against the gold standard were satisfactory for HPV-16, -18, -58, -33, -52, -39, -45, -31, -51, -70 while HPV-71 (63.6%) had suboptimal sensitivity. Though the kappa values between the two tests for many individual genotypes could not be reliably calculated because of low positivity, the kappa values for HPV-16, -52, and -58 were excellent (0.93, 0.96, and 0.95, respectively). CONCLUSION: The modified MY11/GP6+ PCR-based HPV Blot assay is accurate and sensitive for detection and genotyping of HPV in cervical swab samples.

The role of sentinel lymph node biopsy in early-stage cervical cancer: A systematic review.

Pelvic lymphadenectomy procedure is included as part of the standard protocol of radical hysterectomy for women with early-stage cervical cancer (Stage IA to IB1). However, an important sequel to lymphadenectomy procedure is the possible occurrence of lymphedema in the lower abdomen and lower extremities. Previous researches also find that women with lymphedema experience many emotional impacts, including depression, anxiety, and adjustment problems. Only approximately 10% of women with clinical stage IB cervical carcinoma were involved with metastatic disease. If we could better define the relevant lymphatic nodes that must be removed, it is then possible to limit routinely performed lymphadenectomy for regional nodal metastasis in the pelvis, and hence reduce the need for extended surgical staging (para-aortic lymphadenectomy). We systematically reviewed a body of literature and updated available information concerning the current progress on the application of sentinel lymph node biopsy in women with early-stage cervical cancer. All detection methods (preoperative injection of radiocolloid tracer, intraoperative injection of blue dye, or a combination of both techniques) demonstrated reasonable sensitivity (with a few exceptions), high specificity, low false-negative rate and high negative predictive value. The review of the literature in this paper should convince the readers that sentinel lymph node biopsy has the potential to improve the quality of life and the possibility to maintain relapse-free survival for women with cervical cancer. The proper identification of negative sentinel lymph node allows individualized therapy and may preclude the need of lymphadenectomy procedure in most of these women.
