Effect of individual psychological intervention in Chinese women with gynecologic malignancy: a randomized controlled trial.

PURPOSE: To evaluate the effectiveness of psychological intervention in the care of cancer patients and to determine whether routine use of individual psychological therapies is indicated. PATIENTS AND METHODS: Patients with newly diagnosed gynecologic malignancies from August 1999 to November 2000 were recruited and randomly assigned to either a control group receiving routine medical care or to an intervention group receiving individual psychotherapy. A set of fixed-choice, self-report questionnaires assessing the patients' psychological status, quality of life, and their perceptions related to the medical consultations was completed at recruitment and then every 3 months for 18 months. Data analysis was performed according to the intention-to-treat principle by fitting the data into a linear mixed-effects model. Multivariable analyses were performed to examine the effects of confounding factors. RESULTS: One hundred fifty-five patients participated in the trial. There were no statistically significant differences between the two groups at baseline. There was a trend toward better quality of life and functional status and also improvement of the symptoms over time for both groups. No differences were found between the groups in the scores measured by any of the instruments at baseline and at any time points after the cancer diagnosis. Psychological intervention had no significant effects on the psychosocial parameters. CONCLUSION: Routine use of psychological therapies as given in our format has no significant effect on the patients' quality of life and psychological status.

Screening for HIV infection in women with newly diagnosed cervical cancer.

OBJECTIVE: This study aimed to investigate the prevalence of human immunodeficiency virus (HIV) infection in women with cervical cancer and to decide whether HIV testing should be included as part of the initial work-up of invasive cervical cancer. METHODS: This was a prospective case controlled study. Women with newly diagnosed cervical cancer were tested and age-matched women with benign gynecologic conditions were selected as control. Serum samples were tested for HIV I and HIV II antibodies at diagnosis and 3 months later. RESULTS: Two hundred twenty-five consecutive patients with newly diagnosed cervical cancer and two hundred twenty-three age-matched women with benign gynaecological conditions were tested. In comparison with the control, women with cervical cancer started sexual intercourse at an earlier age and had a statistically significant higher number of sexual partners. All the HIV tests were negative. The HIV prevalence rate was estimated to be 0.0-1.6% for both groups. CONCLUSION: HIV screening should not be a part of the initial work-up for cervical cancer in a population with a low background prevalence.

High frequency of mitochondrial genome instability in human endometrial carcinomas.

To investigate the occurrence of somatic mitochondrial DNA (mtDNA) mutations in human primary endometrial carcinomas, we sequenced the D-loop region, the 12S and 16S rRNA genes of mtDNA of cancer tissues and their matched normal controls. About 56% (28 out of 50) of cases carry one or more somatic changes in mtDNA including deletion, point mutation and mitochondrial microsatellite instability (mtMSI), namely the change in length of short base-repetitive sequences of mtDNA. In particular, mtMSI was frequently detected in 89% (25 out of 28) of all the cases carrying somatic changes followed by point mutations (25%; seven out of 28) and deletion (3.5%; one out of 28). The CCCCCTCCCC sequences located in the Hypervariable Regions I and II of the D-loop and 12S rRNA gene are instability hot spot regions in endometrial carcinomas. It is suggested that errors in replication may account for the high frequency of mtMSI in human endometrial carcinomas. The relatively high prevalence of mtMSI may be a potential new tool for detection of endometrial cancer.

Quality of life in women treated with neoadjuvant chemotherapy for advanced ovarian cancer: a prospective longitudinal study.

OBJECTIVE: The purpose was to examine the outcomes of patients with advanced ovarian cancer treated with neoadjuvant chemotherapy, with a special emphasis on the patients' quality of life (QOL). METHODS: Seventeen patients with advanced ovarian cancer were treated with neoadjuvant chemotherapy based on the extent of disease on computer tomography. All patients received combined platinum/paclitaxel chemotherapy. Debulking surgery was performed after three cycles or six cycles of chemotherapy, depending on the response to the chemotherapy. Patients' QOL was studied over time using European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 and was then compared with that of patients treated with conventional treatment in the previous cohort. RESULTS: The response rate to chemotherapy assessed at three cycles was 82.4%. The rate of optimum debulking to residual disease less than 2 cm after chemotherapy was 76.9%, and 38.5% had no gross residual disease after surgery. The median overall survival was 22.9 months. The median disease-free interval was 13.3 months. The overall QOL improved after chemotherapy and this continued to improve up to 12 months. The other functional scales also showed improvements over time, apart from the initial transient deterioration in the role functioning and cognitive functioning at 3 months after chemotherapy. Patients treated with neoadjuvant chemotherapy seem to have better but statistically insignificant difference in QOL parameters than patients treated conventionally. CONCLUSION: Neoadjuvant chemotherapy is an alternative treatment for patients with advanced ovarian cancer in whom the chance of optimal cytoreduction is low. The patients' overall quality of life and functional status improve after neoadjuvant chemotherapy.

A retrospective review on atypical glandular cells of undetermined significance (AGUS) using the Bethesda 2001 classification.

OBJECTIVE: The Bethesda system for reporting cervicovaginal cytologic diagnoses was recently revised in 2001. Pathologists are required to report not only whether the smear favors neoplastic changes, but also the origin of the abnormal cells. In this study, archival smears were reviewed to evaluate the usefulness of the new classification. METHODS: Smears having atypical glandular cells taken between January 1995 and December 1997 were reviewed and subclassified according to the revised Bethesda classification. Case records were then reviewed and cases with discrepancies between the cytological evaluation and corresponding final histological diagnoses were further reviewed. RESULTS: There were 138 smears reviewed. The mean age of the patients was 47 (range, 18 to 78). Thirty-four smears favored neoplasia and 104 favored "NOS" ("not otherwise specified"). Sixty smears favored endocervical origin and 78 endometrial origin. Forty-three patients (31%) had significant pathologies, including 12 (8.7%) patients with high-grade CIN, 2 (1.4%) with low-grade CIN, 5 (3.6%) with HPV infection, 7 (5.1%) with carcinoma of the corpus, 1 (0.7%) with cervical adenocarcinoma in situ, 4 (2.9%) with adenocarcinoma of the cervix, 3 (2.2%) with endometrial hyperplasia, and 5 (3.6%) with carcinoma of the ovary. Two (1.4%) patients had double primary female genital malignancies and 2 patients (1.4%) had extragenital malignancies. Significant correlation was found between smears "favor neoplasia" and a final diagnosis with significant pathology (chi(2) test, P < 0.05). Significant association was found between AGC favored endocervical origin and a final diagnosis with cervical diseases (chi(2) test, P < 0.05). Four of the 43 patients who had significant pathologies had lesions found during their subsequent visits and all of them had cervical smears classified as AGC "favor neoplasia". CONCLUSION: AGC found on cervical smears are an indication for early and intensive investigation.

Risk to breeding success of fish-eating Ardeids due to persistent organic contaminants in Hong Kong: evidence from organochlorine compounds in eggs.

Eggs of two Ardeid species, the Little Egret (Egretta garzetta) and the Black-crowned Night Heron (Nycticorax nycticorax), were collected from two egretries located in the New Territories of Hong Kong with one located near the internationally acclaimed wetland reserve, the Mai Po Marshes, and the other in a remote site (A Chau). The eggs were analysed for organochlorine (OC) compounds including the DDTs, PCBs, hexachlorocyclohexanes (HCHs) and the chlordanes (CHLs). All of the OCs under investigation were detected in the eggs of both species with significantly higher levels in the Little Egret (DDTs, 560-2200; PCBs, 270-1700; CHLs, 81-470 ng g(-1) wet weight) than the Night Heron (DDTs, 210-1200; PCBs, 85-600; CHLs 59-75 ng g(-1) wet weight). The DDTs consisted mainly of DDE with levels ranging from 85% to 95% of the total. The HCHs were at about the same levels in both species (8.4-30 ng g(-1) wet weight). All of the OCs had linear concentration probability distributions on a log-normal basis which were used to evaluate exposure associated with these compounds as part of a probabilistic risk analysis. A linear dose/response relationship for the percentage reduction in the survival of young associated with DDE in eggs was developed. This probabilistic relationship was used to establish the threshold level (1000 ng g(-1) wet weight) at which there was a significant level of reduction in the survival of young above zero and the variability in DDE concentrations at this effect level. Using a threshold level of 1000 ng g(-1), the calculated Risk Quotient (RQ) had a 12.4% probability of RQ exceeding unity with the Night Heron, and 40.9% with the Little Egret. These results indicate that the DDTs in eggs would be expected to be associated with adverse effects on the survival of young of both species, particularly the Little Egret.

Symptoms, coping strategies, and timing of presentations in patients with newly diagnosed ovarian cancer.

OBJECTIVE: The purpose was to explore whether health education on symptoms of ovarian cancer would aid in early detection, by examining the relationship between symptoms, coping strategies, and timing of presentation in patients with newly diagnosed ovarian cancer. METHODS: Eighty women were included. A questionnaire consisting of a series of open questions was designed to collect information on the sequence of events from the onset of symptoms to the diagnosis of ovarian cancer. The Coping Response Inventory (CRI) was used to assess the coping strategies. RESULTS: A majority (90.0%) of women with ovarian cancer did have symptoms before the diagnosis. Abdominal pain or discomfort, abdominal distension, a palpable abdominal mass, menstrual, bowel, or urinary symptoms were the commonly reported symptoms. Eight (10.0%) patients were totally asymptomatic prior to the cancer diagnosis. The presence of bowel symptoms was significantly associated with late stage disease. Most of the patients sought medical advice within 2 weeks from the onset of symptoms. There was no association between the presence of any particular symptom(s) and the timing of presentation. There was also no correlation between the coping strategies and stage of disease and timing of presentation. On average, patients with early stage disease saw one more doctor compared to patients with late stage disease before the affirmative diagnosis of ovarian cancer. CONCLUSION: Most patients presented early after the onset of symptoms. Health education in this regard may not be useful for early diagnosis of ovarian cancer.

The use of music to reduce anxiety for patients undergoing colposcopy: a randomized trial.

OBJECTIVE: The goal of this work was to investigate the impact of music on women's anxiety and perceived pain during colposcopy examination. METHODS: This was a prospective randomized study. Two hundred and twenty women referred for colposcopy for the first time were recruited. They were randomized to either the music or no-music group. Before colposcopy examination, each subject completed a Chinese version of the state anxiety questionnaire (STAI) and assessed the anticipated pain for colposcopy with a visual analog scale (VAS). Slow-rhythm music was played during colposcopy examination in the music group. Subjects in the no-music group were examined in the same setting without music. After colposcopy, each subject completed the STAI form again and assessed their pain during examination by the VAS. RESULTS: Women in the music group experienced significantly less pain (mean VAS 3.32 [95% CI 2.86-3.78] vs 5.03 [4.54-5.52], P<0.001) and lower anxiety (mean STAI 39.36 [95% CI 37.33-41.39] vs 44.16 [41.82-46.49], P = 0.002) during colposcopy examination than women in the no-music group. On linear regression analysis, the factors significantly affecting anxiety during colposcopy were anxiety score at enrollment, pain score during colposcopy, and whether or not the women had listened to music during the colposcopy examination. The factors significantly affecting the pain scores were whether the women had listened to music during the procedure and the final anxiety scores. CONCLUSIONS: Music is a simple, inexpensive, and easily used strategy to minimize anxiety and pain during colposcopy examination.

E-cadherin expression is silenced by DNA methylation in cervical cancer cell lines and tumours.

A previous study showed E-cadherin expression was lost in some cervical cancer cell lines and tumours. This study was designed to clarify the significance of DNA methylation in silencing E-cadherin expression. We examined promoter methylation of E-cadherin in five cervical cancer cell lines and 20 cervical cancer tissues using methylation-specific PCR (MSP) and bisulphite DNA sequencing. The correlation of E-cadherin methylation and expression together with methyltransferase (DNMT1) were further studied. We found that hypermethylation of E-cadherin was involved in five cervical cancer cell lines and 40% (8/20) of cervical cancer tissues. E-cadherin protein was lost in 6/8 (75%) samples and 3/5 (60%) cell lines with promoter methylation. E-cadherin methylation was significantly correlated with increased DNMT1. Using an antisense DNMT1 oligo to transfect into SiHa HeLa C33A cell line, E-cadherin protein was re-expressed. We concluded that loss of E-cadherin expression was in part correlated with DNA methylation and DNMT1 expression in cervical cancer.

Diagnosis and management of gestational trophoblastic neoplasia.

The FIGO Committee Report on the FIGO 2000 staging for gestational trophoblastic disease included criteria for the diagnosis of gestational trophoblastic neoplasia (GTN). It recommended investigative tools for diagnosing metastases. Anatomical and prognostic indicators were combined into a stage : risk score to stratify patients into low and high-risk groups. This is the first staging system to incorporate inclusive criteria that are likely to be adopted universally. The diagnostic evaluation of GTN is presented. The rationale of using the various investigative tools is discussed. The problem of measuring human chorionic gonadotrophin (hCG) levels using commercial kits and the phenomenon of 'phantom hCG' is explored. The use of single agent chemotherapy for low-risk disease versus multi-agent chemotherapy for high-risk disease is discussed. Controversies regarding when to stop chemotherapy are explored with a view to minimizing the short and long-term toxicity, in particular the small risk of developing a second malignancy. Recommendations for the follow up of patients after chemotherapy with particular reference to contraceptive advice and future pregnancies are discussed in the light of current evidence.

Measuring quality of life in Chinese cancer patients: a new version of the Functional Living Index for Cancer (Chinese).

INTRODUCTION: Since its translation into Chinese, the Functional Living Index for Cancer (FLIC) has not been widely received due to some of its difficulties. We modified its visual analogue scale (VAS) to an ordered categorical scale and changed some of the wording in the instrument. This study examined the measurement properties of the modified FLIC. MATERIALS AND METHODS: The modified version of FLIC and the Functional Assessment of Cancer Therapy (FACT-G Chinese version 4) were filled in by 140 patients recruited from the National Cancer Centre Singapore. The patients' FLIC scores were compared with their clinical characteristics to establish known-group validity. Convergent and divergent validity of FLIC were examined by correlation analysis with FACT-G and its sub-scales. Cronbach's alpha and relative efficiency were also examined. RESULTS: FLIC and most of its sub-scales could indicate a clear and statistically significant difference of quality of life (QOL) according to patients' performance status and treatment status. FLIC strongly correlated with FACT-G. The Physical, Psychological, and Symptoms sub-scales of FLIC converged to and diverged from FACT-G sub-scales as conceptually expected. Cronbach's alpha indicated a satisfactory level of reliability. FLIC appeared to be more efficient than FACT-G, meaning that a smaller sample size will be required for FLIC than for FACT-G to achieve the same research purpose. CONCLUSIONS: The modified version of FLIC was found to have achieved satisfactory measurement properties. This is a user-friendly alternative to the original FLIC.

Monitoring of serum squamous cell carcinoma antigen levels in invasive cervical cancer: is it cost-effective?

OBJECTIVE: The aim of this study was to assess the cost-effectiveness of serial squamous cell carcinoma antigen (SCC) monitoring in the clinical setting. METHODS: All patients with squamous cell carcinoma of the cervix and SCC measurement from 1994 to 1999 were reviewed. The cost of the investigations, including blood tests, X rays, and computer tomography; and clinic visits were adjusted to 2001 dollars for all cases over the 6-year study period. The effectiveness measure was the number of cases detected by SCC monitoring before the onset of clinical symptoms or abnormal physical examination findings. Altered clinical management due to early detection was considered successful. RESULTS: Two thousand eight hundred fifty-one SCC antigen assays were performed from 384 patients. An elevated pretreatment SCC level was associated with poorer cumulative survival over time (P < 0.05). Fifty-five patients had recurrences, with 10 local and 45 distant recurrences. SCC levels were elevated in 47 patients (85%). The median lead time was 7.8 months. The cost of finding 1 recurrence was US$4750. SCC monitoring does not alter clinical management and has no advantage over clinical examination in detecting local recurrence. Most of the recurrent diseases were detected too late for curative treatment. Only 1 patient, in whom the diagnosis could have been made by clinical examination without SCC monitoring, may have potentially benefited from exenteration. CONCLUSION: Posttreatment SCC monitoring is not cost-effective in the absence of curative treatment for distant spread of disease.

Detection of human papillomavirus DNA in malignant lesions from Chinese women with carcinomas of the upper genital tract.

OBJECTIVE: The aim of this study was to determine the prevalence of high-risk oncogenic human papillomaviruses (HPVs) in malignant lesions from Hong Kong Chinese women with carcinomas of the upper genital tract. METHODS: The presence of high-risk HPVs in 55 cases of endometrial adenocarcinomas and 60 cases of primary epithelial ovarian cancers was detected by polymerase chain reaction (PCR) using consensus primers complementary to late 1 (L1) gene of the genital HPVs. Amplified PCR products were verified and typed by Southern blot analysis using (32)P-labeled DNA probes prepared from cloned HPV-16 and -18 plasmids. To confirm the presence of high-risk HPV types in the tumor tissues, PCR amplification using HPV type 16- and 18-specific primers for part of the E6 gene were also carried out. RESULTS: While HPV-18 was not detected, HPV-16 DNA sequences were identified in 5 (9.1%) of the 55 studied endometrial carcinoma samples. Of the 5 HPV-16-positive cases, there were 4 stage I, and 1 stage II endometrial cancer. In addition, 6 (10%) of the 60 epithelial ovarian carcinomas were positive for high-risk HPVs, which included 5 cases with HPV-16 and 1 case with HPV-18. Clinical staging revealed that 5 of the 6 HPV-positive cases were stage I and the remaining case was stage III ovarian cancer. Histology of the 6 HPV-positive cases showed that there were 1 case of clear-cell adenocarcinoma, 1 case of mucinous cystadenocarcinoma, and 4 cases of mucinous tumor of borderline malignancy. No other HPV types were detected. CONCLUSION: High-risk HPV was detected in approximately 10% of the tumor samples from women with upper genital tract carcinomas. As compared to the high positive rate of HPV infections in cervical cancer, it appears that HPV infection plays a relatively minor role in the pathogenesis of endometrial and ovarian carcinomas.

Intracranial germ cell tumour: experience of a Singaporean institution over 11-year period.

BACKGROUND: Intracranial germ cell tumours (IGCT) are rare. We present our experience in Therapeutic Radiology Department, National Cancer Centre, Singapore. METHODS: A retrospective study was conducted through case notes review on 25 patients with IGCT referred between January 1988 and January 1999. RESULTS: The median age at diagnosis was 13 years (range 6-22). The tumours were mainly pineal germinoma (72%). Median follow-up for living patients was 2.57 years (range 0.12-10.8). Median radiotherapy (RT) dose to whole brain, primary site and spine was 35.3,54 and 30 Gys respectively. Four to six cycles of BEP or JEB chemotherapy (CM) were given in 10 patients. As for the whole study group, the seven-year overall survival (OS) and recurrence-free survival (RFS) were 86% (95% CI 72-100) and 78% (95% CI 60-100) respectively. The 10-year OS and RFS were 65% (95% CI 36-100) and 78% (95% CI 60-100) respectively. The germinoma group had 75% 10-year OS and 86% 10-year RFS. Mixed germinoma and non-germinoma germ cell tumours (NGGCT) group had 50% one-year RFS and 44% two-year OS. Acute side-effects of RT and CM were minimal. There was no statistically significant difference in side-effects when treatment modalities were compared. CONCLUSION: In the treatment of intracranial germinoma, we recommend biopsy and CSRT. Primary chemotherapy (+/- low-dose cranial RT) should be used in the protocol or clinical trial settings. Chemo-radiotherapy is recommended for mixed germinoma and NGGCT. A multicentre trial is needed to address various controversial issues.

Outcome of an interventional program for scabies in an Indigenous community.

OBJECTIVE: To implement an intervention program for reducing the prevalence of scabies in a large Northern Territory Aboriginal community. DESIGN: Prospective, longitudinal screening, intervention and follow-up study. PARTICIPANTS AND SETTING: All children aged 5 years and under in one of the largest Aboriginal communities in the Northern Territory, total population, approximately 2,200 (95% Indigenous). MAIN OUTCOME MEASURES: A decrease in prevalence of scabies, infected scabies and non-scabies pyoderma over seven months. RESULTS: The number of children aged 5 years and under screened intially and at the three follow-up screenings ranged from 201 to 242 (more than 98% of those eligible on each occasion). The prevalences of scabies, infected scabies and non-scabies pyoderma before intervention were 35%, 12% and 11%, respectively. At 6 weeks postintervention these had decreased to 3%, 1% and 4%, respectively; low prevalences were maintained at four and seven months. CONCLUSIONS: This intervention, which was based on community motivation, involvement and control, successfully reduced the prevalence of scabies. Continuing community health education and regular screening will be crucial in controlling scabies. The methods and results of this study may be helpful in developing a coordinated program for all remote Aboriginal communities in the area.

High incidence of somatic mitochondrial DNA mutations in human ovarian carcinomas.

To investigate the potential role of somatic mitochondrial DNA (mtDNA) mutations in tumorigenesis, the occurrence of mutations in mtDNA of ovarian carcinomas was studied. We sequenced the D-loop region of mtDNA of 15 primary ovarian carcinomas and their matched normal controls. Somatic mtDNA mutations were detected in 20% (3 of 15) tumor samples carrying single or multiple changes. Complete sequence analysis of the mtDNA genomes of another 10 pairs of primary ovarian carcinomas and control tissues revealed somatic mtDNA mutations in 60% (6 of 10) of tumor samples. Most of these mutations were homoplasmic, and most were T-->C or G-->A transitions, but one represented a differential length within a run of identical C residues. A region of mtDNA sequence including the 16S and 12S rRNA genes, the D-loop and the cytochrome b gene, may represent the zone of preferred mtDNA mutation in ovarian cancer. The high incidence of mtDNA mutations found in ovarian carcinomas and other human cancers suggests that genetic instability of mtDNA might play a significant role in tumorigenesis.

Low incidence of HPV DNA in sera of pretreatment cervical cancer patients.

OBJECTIVE: The aim of this study was to investigate the feasibility of using DNA in the circulation as a diagnostic tool for cervical cancer. METHODS: We used PCR followed by Southern hybridization to detect human papillomavirus (HPV) DNA in serum samples taken from patients of cervical cancer before treatment. RESULTS: A total of 60 samples were analyzed. In a set of 40 samples, without knowledge of the HPV DNA status in the corresponding cervical carcinomas, we could detect 8 (20%) positive samples, of which 7 (17.5%) were HPV 16 and 1 (2.5%) was HPV 18. In another set of 20 samples, known to be HPV 16 infected in the corresponding cervical carcinomas, we detected only 4 (20%) HPV-16-positive samples. The occurrence of HPV DNA in sera of cervical cancer patients seems sporadic. CONCLUSION: The low incidence indicates that serum HPV DNA has limited application in the diagnosis of cervical cancer.

A longitudinal study on quality of life after gynecologic cancer treatment.

OBJECTIVE: The objective was to describe the pattern of quality of life (QOL) over time and to assess the impact of age, symptoms, disease parameters, and treatment on the overall QOL. METHODS: A longitudinal study on patients with newly diagnosed gynecologic cancer using individual patients as their own control was performed. The 33-item EORTC QLQ-C30(+3) was used as the QOL measure. Patients were assessed before treatment, after completion of treatment, and at 6, 12, and 24 months. Spearman's correlation analyses were performed. A mixed effect model was fitted to the data. Bonferroni pairwise comparisons were used to analyze the different variables. RESULTS: One hundred forty-four women completed the study. Overall QOL improved after the completion of treatment but remained the same throughout the 2 years after treatment. The individual patient's QOL before treatment was insignificant while the impact of treatment on the individual patient was significant in determining QOL after treatment. There was a strong correlation for all time points in most factors, indicating that the global health status, functional scales, and symptom scales exhibit a dependent change over time. Relief in symptoms was associated with improvements in functional scales. The scores on overall QOL were lower for younger patients and for patients treated with chemotherapy than for patients treated with surgery. CONCLUSIONS: Strategies for supportive care need to focus on symptom management. Psychosocial interventions, to be effective, should include all patients and should aim to reduce the impact of treatment on the individual patient.
