- Human papillomaviruses (HPV) are established as a major cause of cervical carcinoma. However, causality inference is dependent on prospective evidence showing that exposure predicts risk for future disease. Such evidence is available for squamous cell carcinoma, but not for cervical adenocarcinoma. We followed a population-based cohort of 994,120 women who participated in cytological screening in Sweden for a median of 6.7 years. Baseline smears from women who developed adenocarcinoma during follow-up (118 women with in situ disease and 164 with invasive disease) and their individually matched controls (1,434 smears) were analyzed for HPV using PCR. Conditional logistic regression was used to estimate odds ratios (OR) of future adenocarcinoma with 95% confidence intervals (CI). Being positive for HPV 16 in the first cytologically normal smear was associated with increased risks for both future adenocarcinoma in situ (OR: 11.0, 95% CI: 2.6-46.8) and invasive adenocarcinoma (OR: 16.0, 95% CI: 3.8-66.7), compared to being negative for HPV 16. Similarly, an HPV 18 positive smear was associated with increased risks for adenocarcinoma in situ (OR: 26.0, 95% CI: 3.5-192) and invasive adenocarcinoma (OR: 28.0, 95% CI: 3.8-206), compared to an HPV 18 negative smear. Being positive for HPV 16/18 in 2 subsequent smears was associated with an infinite risk of both in situ and invasive adenocarcinoma. In conclusion, infections with HPV 16 and 18 are detectable up to at least 14 years before diagnosis of cervical adenocarcinoma. Our data provide prospective evidence that the association of HPV 16/18 with cervical adenocarcinoma is strong and causal.

- OBJECTIVE: Patient-physician communication and patient satisfaction are important elements of cancer care. Trust is considered to be crucial for the patient-physician relationship, yet little is to be found in the literature regarding what factors may influence trust. METHODS: We assessed predictors of trust in health-care professionals and in the medical care by administering two questionnaires, one at start of chemotherapy treatment and one at the time of the third chemotherapy cycle, to 304 parents of children with newly diagnosed cancer at the Children's Cancer Hospital in Cairo, Egypt. RESULTS: Parents' trust in the medical care at the time of the child's third chemotherapy cycle was significantly associated with the following at the start of treatment: having received at least moderate information about the disease (relative risk (RR) 13.2; 95% CI 7.8-22.3) and the treatment (RR 17.2; 95% CI 9.5-31.4), having the opportunity to communicate with the child's physicians (RR 21.3; 95% CI 11.7-38.8), being satisfied with the physicians conversation style (RR 30.6; 95% CI 14.4-64.9), having the emotional needs met (RR 22.2; 95% CI 11.8-41.9), and being met with care by the child's physicians (RR 32.0; 95% CI 15.2-67.7). After multivariable model selection, the strongest predictor of trust at the time of the third chemotherapy cycle was to be met with care at the start of treatment. CONCLUSION: Parents being met with care by the child's physicians at the beginning of the child's chemotherapy treatment develop an increased trust in the medical care.

- AIM: To investigate adherence to medical regimen and predictors for non-adherence among children with cancer in Egypt.METHODS: We administered two study specific questionnaires to 304 parents of children diagnosed with cancer at the Children's Cancer Hospital in Cairo, Egypt, one before the first chemotherapy treatment and the other before the third. The questionnaires were translated to colloquial Egyptian Arabic, and due, to the high illiteracy level in Egypt an interviewer read the questions in Arabic to each parent and registered the answers. Both questionnaires consisted of almost 90 questions each. In addition, a Case Report Form was filled in from the child's medical journal. The study period consisted of 7 mo (February until September 2008) and we had a participation rate of 97%. Descriptive statistics are presented and Fisher's exact test was used to check for possible differences between the adherent and non-adherent groups. A P-value below 0.05 was considered significant. Software used was SAS version 9.3 for Windows (SAS Institute Inc., Cary, NC, United States).RESULTS: Two hundred and eighty-one (90%) parents answered the second questionnaire, regarding their child's adherence behaviour. Approximately two thirds of the children admitted to their third chemotherapy treatment had received medical recommendations upon discharge from the first or second chemotherapy treatment (181/281, 64%). Sixty-eight percent (123/181) of the parents who were given medical recommendations reported that their child did not follow the recommendations. Two main predictors were found for non-adherence: child resistance (111/123, 90%) and inadequate information (100/123, 81%). In the adherent group, 20% of the parents (n = 12/58) reported trust in their child's doctor while 14 percent 8/58 reported trust in the other health-care professionals. Corresponding numbers for the non-adherent group are 8/123 (7%) for both their child's doctor and other health-care professionals. Almost all of the parents expressed a lack of optimism towards the treatment (116/121, 96%), yet they reported an intention to continue with the treatment for two main reasons, for the sake of their child's life (70%) (P = 0.005) and worry that their child would die if they discontinued the treatment (81%) (P < 0.0001).CONCLUSION: Non-adherence to medical regimen is common among children diagnosed with cancer in Egypt, the main reasons being child resistance and inadequate information.

- OBJECTIVE: Informing the child about his/her diagnosis and treatment plan is essential; research has shown that it is related to the patient's quality of life and adherence to medication.METHODS: For 7 months during 2008 (February to September), 2 study-specific questionnaires were constructed and administered to 304 parents of children diagnosed with cancer at the Children's Cancer Hospital Egypt.RESULTS: Among the 313 eligible parents of children diagnosed with cancer, 304 (97%) answered the first questionnaire and 281 (92%) answered the second questionnaire. We found that nearly three-quarters (72%) of the parents had their child's cancer diagnosis communicated by the physician. Among the 72%, the rate of the children present with the parent or parents during the disease disclosure conversation was 39% (n = 85/219). The majority of the children were in the age group 5-18 years (55%).CONCLUSIONS: Our findings indicate that cancer disclosure at the Children's Cancer Hospital is to a certain degree common; yet even when disclosure does take place, it is mainly in the absence of the child. Moreover, the information provided during the conversation may not be fully comprehended by the parent or the child because of the physician's misleading use of terms when disclosing the disease. Therefore, better practice should be developed for disease disclosure, and proper communication should be established between the patients and the provider; patient autonomy should also have an influence in the clinical practice.

- BACKGROUND: Infection with certain types of human papillomavirus (HPV), which is common among young women, increases the risk of cervical cancer. However, less than 1% of young women positive for oncogenic types of HPV develop cervical cancer. We investigated whether the amount of HPV DNA is a useful predictor of progression to cervical carcinoma in situ. METHODS: We estimated the amount of HPV 16 DNA by a PCR that uses the 5'-exonuclease (Taqman) method, in 478 women with cervical carcinoma in situ and 608 individually matched controls. To adjust for differences in the amount of genomic DNA between samples, we estimated the amount of a nuclear gene (beta-actin). We studied multiple smears (total 3835 archived samples) from each woman, taken over periods of up to 26 years, that covered normal cytology to development of cervical cancer. FINDINGS: The risk of cervical carcinoma in situ increased with the amount of HPV 16 DNA. Analysis of the first smear from each woman, collected a mean of 7.8 years before cancer diagnosis, showed that women with the 20% highest amount of HPV 16 DNA were at a 60-fold higher risk of developing cervical carcinoma in situ than women negative for HPV 16. The first smear samples were classified as normal by squamous-cell cytology. INTERPRETATION: Analysis of the amount of HPV DNA can predict cancer risk at a stage when current screening methods are uninformative. Testing for the amount of HPV 16 DNA during gynaecological health checks might strikingly improve our ability to distinguish between infections that have a high or low risk of progressing into cervical cancer.

- Grief over the loss of a family member may cause physical and mental illness, but an association between bereavement and cancer risk has not been established. Based on the Swedish National Cervical Screening Register (1969-2011) including 14,011,269 smears from 2,466,107 women, we conducted two nested case-control studies to examine the associations of bereavement (i.e., loss of a family member due to death) with abnormal cytology (390,310 first abnormal and 1,951,319 normal smears) and in situ/invasive cervical cancer (75,128 case and 375,640 control women), both individually matched on year of birth and screening adherence. Among 1,696 of the control women, we further investigated bereavement in association with HPV infection, both HPV16 and other HPV types. Bereavement was consistently associated with a 4-9% increased risk for first abnormal cytology, in situ and invasive cervical cancer (all P<0.02). The associations became stronger when multiple losses, loss of child, sibling or spouse, and loss due to unnatural cause were analyzed separately (P for trend or difference<0.0001), and for women with high screening adherence (P for difference<0.05). Among 1,696 women who had not developed cervical cancer, we further investigated the link between bereavement and HPV infection. Bereavement was associated with a 62% increased risk of HPV16 infection, high viral load, and recurrent infection, and was also more strongly associated with HPV infections designated as high-risk compared to low-risk determinants of cervical carcinogenesis. Collectively, our findings demonstrate that bereavement is associated with an increased risk of developing cervical cancer. Further, they suggest that this association may be attributed to stress-induced oncogenic HPV infections.

- Background: Depression often develops undetected; to make treatment possible, a single-item screening question may be useful. Patients and methods: We attempted to compare the accuracy of the single-item question ‘Are you depressed?’ with the seven-item Depression subscale of the Hospital Anxiety and Depression Scale (HADS-D) among 1192 Swedish testicular cancer survivors. Results: We obtained information from 974 men (82%). Fifty-nine men (6%) answered ‘Yes’ to the question ‘Are you depressed?’ while 118 (12%) answered ‘I don't know’ and 794 (82%) answered ‘No’. Among the 794 men who answered ‘No’ to the question ‘Are you depressed?’, 790 (99.5%) were not considered as depressed according to HADS-D 11+. Of those answering ‘Yes’, 34% (20/59) were identified as depressed according to the same cut-off. Sensitivity of ‘Yes’ compared with HADS-D ≥11 was 61%, rising to 88% when ‘Yes’ and ‘I don't know’ were combined. Conclusion: In a population of men with a prevalence of depression similar to that of the normal population, almost none of those responding ‘No’ to the written question ‘Are you depressed?’ were depressed according to HADS-D ≥11. Adding the category ‘I don't know’ increases sensitivity in detecting depression.
