Novel mutations in the BRCA1 and BRCA2 genes in Iranian women with early-onset breast cancer
BACKGROUND:
Breast cancer is the most common female malignancy and a major cause of death in middle-aged women. So far, germline mutations in the BRCA1 and BRCA2 genes in patients with early-onset breast and/or ovarian cancer have not been identified within the Iranian population.
METHODS:
With the collaboration of two main centres for cancer in Iran, we obtained clinical information, family history and peripheral blood from 83 women under the age of 45 with early-onset breast cancer for scanning of germline mutations in the BRCA1 and BRCA2 genes. We analysed BRCA1 exons 11 and BRCA2 exons 10 and 11 by the protein truncation test, and BRCA1 exons 2, 3, 5, 13 and 20 and BRCA2 exons 9, 17, 18 and 23 with the single-strand conformation polymorphism assay on genomic DNA amplified by polymerase chain reaction.
RESULTS:
Ten sequence variants were identified: five frameshifts (putative mutations – four novel); three missense changes of unknown significance and two polymorphisms, one seen commonly in both Iranian and British populations.
CONCLUSIONS
Identification of these novel mutations suggests that any given population should develop a mutation database for its programme of breast cancer screening. The pattern of mutations seen in the BRCA genes seems not to differ from other populations studied. Early-onset breast cancer (less than 45 years) and a limited family history is sufficient to justify mutation screening with a detection rate of over 25% in this group, whereas sporadic early-onset breast cancer (detection rate less than 5%) is unlikely to be cost-effective
Coronary Artery Bypass Grafting: Simultaneous Head and Neck Mass Surgery
Background: Coronary artery disease (CAD) and cancer have common risk factors. According to the necessity of mass resection in patients with CAD at the same time, we decided to do neck and head mass resection and coronary artery bypass grafting (CABG) simultaneously and assess the results.Methods: The current study was done on patients who were candidates for simultaneous head and neck mass resection and CABG. The patients’ files were extracted, the information and complications were recorded in a questionnaire, and then necessary data were extracted.Results: Totally 9 patients (3 females and 6 males) with a mean age of 69.11 ± 6.67 standard deviation years were studied. The most common site of squamous cell carcinoma in this study was tongue. Infection occurred in three patients, two of which (66.66%) died. Side effects occurred in four patients.Conclusions: It seems that, according to the anatomical position of neck mass, proximity to the airways and large blood supply in that area, and also because of inappropriate access to the anatomical zones, the survival rate and complications in this surgical setting (simultaneous surgeries) are different from that of other studies. It seems that further studies are needed to be done with the subject of concomitant head and neck mass surgery and CABG this time with a larger number of patients
Weight, height, body mass index and risk of breast cancer in postmenopausal women: a case-control study
Quality of life in patients with breast cancer before and after diagnosis: an eighteen months follow-up study
<p>Abstract</p> <p>Background</p> <p>Measuring quality of life in breast cancer patients is of importance in assessing treatment outcomes. This study examined the impact of breast cancer diagnosis and its treatment on quality of life of women with breast cancer.</p> <p>Methods</p> <p>This was a prospective study of quality of life in breast cancer patients. Quality of life was measured using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and its breast cancer supplementary measure (QLQ-BR23) at three points in time: baseline (pre diagnosis), three months after initial treatment and one year after completion of treatment (in all 18 months follow-up). At baseline the questionnaires were administered to all suspected identified patients while both patients and the interviewer were blind to the final diagnosis. Socio-demographic and clinical data included: age, education, marital status, disease stage and initial treatment. Repeated measure analysis was performed to compare quality of life differences over the time.</p> <p>Results</p> <p>In all, 167 patients diagnosed with breast cancer. The mean age of breast cancer patients was 47.2 (SD = 13.5) years and the vast majority (82.6%) underwent mastectomy. At eighteen months follow-up data for 99 patients were available for analysis. The results showed there were significant differences in patients' functioning and global quality of life at three points in time (P < 0.001). Although there were deteriorations in patients' scores for body image and sexual functioning, there were significant improvements for breast symptoms, systematic therapy side effects and patients' future perspective (P < 0.05).</p> <p>Conclusion</p> <p>The findings suggest that overall breast cancer patients perceived benefit from their cancer treatment in long-term. However, patients reported problems with global quality of life, pain, arm symptoms and body image even after 18 months following their treatments. In addition, most of the functional scores did not improve.</p
i Sexual function in breast cancer patients: a prospective study from Iran
Background: Sexual function in patients with breast cancer especially in younger patients is an important issue from clinical and psychosocial perspectives. This study aimed to assess sexual function among Iranian breast cancer patients. Methods: This was a prospective study of sexual function in breast cancer patients attending the Cancer Institute of Iran. Sexual function was assessed using the Female Sexual Function Index (FSFI) at two points in time: baseline (pre-treatment) and after completion of cancer treatment at follow-up visits (post-treatment). Pre- and posttreatment data were compared. In addition logistic regression analysis was performed to find out factors that contributing to post-treatment sexual dysfunction. Results: In all 277 breast cancer patients were approached. Of these, 231 patients (83%) were sexually active and data for 216 patients (93.5 % of sexually active patients) were available at pre-and post-treatment. Overall pre- and post-treatment sexual dysfunction was found to be 52 % and 84%, respectively indicating a significant deterioration in sexual function among breast cancer patients. The results obtained from multiple logistic regression analysis indicated that younger age [OR = 0.95, 95 % CI = 0.93-0.98; P = 0.04], receiving endocrine therapy [OR = 3.34, 95% CI = 1.37-7.91; P = 0.007] and poor sexual function at pre-treatment [OR = 12.3, 95 % CI = 3.93-39.0; P < 0.0001
Higher incidence of premenopausal breast cancer in less developed countries; myth or truth?
Background: Fundamental etiologic differences have been suggested to cause earlier onset of breast cancer in less developed countries (LDCs) than in more developed countries (MDCs). We explored this hypothesis using world-wide breast cancer incidence data. Methods: We compared international age-standardized incidence rates (ASR) of pre- (<50 years) and postmenopausal (≥50 years) breast cancers as well as temporal trends in ASRs of pre-and postmenopausal breast cancer among selected countries during 1975–2008. We used joinpoint log-linear regression analysis to estimate annual percent changes (APC) for premenopausal and postmenopausal breast cancer in the northern Europe and in Black and White women population in the US. Results: Premenopausal breast cancers comprised a substantially higher proportion of all incident breast cancers in LDCs (average 47.3%) compared to MDCs (average 18.5%). However, the ASR of premenopausal breast cancer was consistently higher in MDCs (29.4/100,000) than LDCs (12.8/100,000). The ASR of postmenopausal cancer was about five-fold higher in the MDCs (307.6/100,000) than the LDCs (65.4/100,000). The APC of breast cancer in Denmark was substantially higher in postmenopausal (1.33%) than premenopausal cancer (0.98%). Higher incidence of breast cancer among the white than black women in the US was pertained only to the postmenopausal cancer. Conclusion: The substantial and consistent lower age-specific incidence of breast cancer in LDCs than in MDCs contradicts the theory of earlier onset. Demographic differences with fewer old women in LDCs and lower prevalence of risk factors of postmenopausal cancer are the most likely explanation to the lower mean age at diagnosis in these countries
Differentiation of Out-of-Pocket Expenditures in Cancer Patients; A Case Study in the Cancer Institute of Iran
Background: The Cancer Institute of Iran, located in Tehran (Iran’s capital city), is a national specialized center for cancer. Cancer patients from all over the country refer to it. This study compared the out-of-pocket (OOP) expenditures of patients from Tehran and patients from other parts of Iran who were hospitalized in this center.
Methods: This cross-sectional study included all patients over 18 years of age with head and neck or digestive system cancer who were actively undergoing primary treatment in the Cancer Institute of Iran located in Tehran (the capital city). Data was collected through a structured interview with the patients themselves and/or their companions and then analyzed using SPSS16 software.
Results: Direct medical costs of patients from Tehran were much higher than those of patients from other provinces. In contrast, the average direct non-medical costs including transportation, accommodation, food, etc. of patients from other provinces were significantly higher than those of patients from Tehran, and 53% of patients borrowed money for their treatments.
Conclusion: It seems necessary to develop new supportive policies to alleviate financial costs for cancer patients and help them manage their cancers effectively. Patients from the provinces faced additional costs for travel, food, and accommodations which complicated their access to special services. Establishing and improving specialized cancer centers in other cities can reduce the burden of out-of-pocket expenditures for patients from remote areas.
 
Tubo-ovarian abscess in a virgin girl
Background: Tubo-ovarian abscess as a serious complication of pelvic
inflammatory disease is very uncommon in sexually inactive girls. Case:
We report a case of tubo-ovarian abscess in a 24-year-old sexually
inactive girl with transverse vaginal septum who was presented with
abdominal pain and a pelvic mass and without prior surgical history and
no evidences of appendicitis, inflammatory bowel disease, or cancer. A
huge unilateral tubo-ovarian abscess was recognized at laparotomy.
Unilateral salpingoophorectomy, hysterectomy and postoperative
antibiotic therapy cured the patient. Conclusion: Early diagnosis and
treatment are essential to prevent further sequel including
infertility, ectopic pregnancy, and chronic pelvic pain which cause
morbidity
