Trends of uterine carcinosarcoma in the United States / 부인종양

OBJECTIVE: Uterine carcinosarcoma (UCS) is a rare type of high-grade endometrial cancer (EC) that has been understudied with population-based statistics due to its rarity. This study examined temporal trends in the proportion of UCS among women with EC. METHODS: This is a retrospective observational study examining The Surveillance, Epidemiology, and End Results program between 1973–2013. Primary EC cases were eligible for analysis, and a time-specific proportion of UCS was examined during the study period. RESULTS: UCS was seen in 11,000 (4.7%) women among 235,849 primary EC cases. Mean age at UCS diagnosis increased from 65.9 to 71.7 years between 1973–1989 and then decreased from 71.7 to 67.0 years between 1989–2013 (both, p < 0.001). Proportion of Black women significantly increased during the study period (11.9%–20.0%, p < 0.001), whereas the proportion of White women decreased from 86.0% to 60.5% between 1987–2013 (p < 0.001). There was a significant increase in the proportion of UCS among primary EC from 1.7% to 5.6% between 1973–2013 (p < 0.001). Among type II ECs (n=76,118), the proportion of UCS also increased significantly from 6.0% to 17.5% between 1973–2013 (p < 0.001). An increasing proportion of UCS was seen in both young and older women but the magnitude of interval increase was larger in the older age group between 1973–2013 ( < 60 years, from 1.3% to 3.3%. p < 0.001; and ≥60 years, from 2.6% to 7.0%, p < 0.001). CONCLUSION: Our study demonstrated that the proportion of UCS has significantly increased among EC, accounting for more than 5% in recent years.

Trends in single women with malignancy of the uterine cervix in United States / 부인종양

OBJECTIVE: To examine trends and characteristics of single women with malignancy of the uterine cervix. METHODS: This is a retrospective observational study examining the United States population-based tumor registry (the Surveillance, Epidemiology, and End Results program). Time-specific trends in single marital status were examined in 3,294,208 women among 12 common female malignancies including 87,151 women with uterine cervical malignancy between 1973 and 2013. RESULTS: While the proportion of single women in the majority of malignancies increased during the study time, the proportion of single women with cervical malignancy significantly increased more than in other malignancies (29.3% in 2013 from 6.3% in 1973). There was a surge in the proportion of single women with cervical malignancy starting in the early 1990s, exhibiting the largest annual percentage rate change (APC) among all examined malignancies (1.8%; 95% confidence interval [CI]=1.6, 2.0; p < 0.001). There was a significant decrease in the proportion of women aged < 40 years with cervical malignancy between 1989 and 2013 (APC, −1.2%; 95% CI=−1.4, −1.0; p < 0.001). However, when stratified by age, the proportion of single women aged ≥40 years increased significantly during the time (APC, 2.7%; 95% CI=2.3, 3.2; p < 0.001) but did not in those who were < 40 years (APC, 0.1%; 95% CI=−0.7, 0.6; p=0.850). CONCLUSION: The proportion of single women with malignancy of the uterine cervix has significantly increased in the past 4 decades. This increase was most dramatic in single women aged ≥40 years. Improving screening strategies in single women aged ≥40 years may help reduce the incidence of this malignancy.

Teenage pregnancy complicated by primary invasive ovarian cancer: association for oncologic outcome / 부인종양

OBJECTIVE: To examine survival of teenage women with pregnancies complicated by primary ovarian cancer. METHODS: This is a secondary analysis of a previously organized systematic literature review of primary ovarian cancer diagnosed during pregnancy. Cases eligible for analysis were patients whose age at cancer diagnosis and survival outcome were known (n=201). Pregnancy and oncologic outcome were then examined based on patient age. RESULTS: These were comprised of 95 (47.3%) epithelial ovarian cancers (EOCs), 82 (40.8%) malignant germ cell tumors (MGCTs), and 24 (11.9%) sex-cord stromal tumors (SCSTs). Teenage pregnancy was seen in 21 (10%) cases, and was highest among the SCST group compared to the other cancer types (EOC, 1.1%; MGCT, 14.6%; and SCST, 29.2%, p 0.05); however, teenage pregnancy was significantly associated with an increased risk of serious maternal/neonatal adverse events (50% vs. 22.7%, p = 0.013). On univariable analysis, teenage pregnancy was significantly associated with decreased ovarian cancer-specific survival (5-year rate: age ≥ 30, 79.6%; age 20–29, 87.2%; and age < 20, 41.6%; p < 0.001). On multivariable analysis controlling for calendar year, cancer type, cancer stage, and gestational age at ovarian cancer diagnosis, teenage pregnancy remained an independent prognostic factor for decreased ovarian cancer-specific survival compared to women aged ≥ 30 (adjusted-hazard ratio=4.71; 95% confidence interval=1.17–18.9; p = 0.029). CONCLUSION: Teenage women with pregnancies complicated by primary ovarian cancer may be at increased risk of poor survival from ovarian cancer.

Paroxysmal orthostatic tachycardia syndrome [POTS] with co-existing chronic fatigue syndrome: a review of three cases and discussion

Orthostatic intolerance appears in many guises including overt dysautonomia, vasovagal syncope and orthostatic tachycardia. We present details of three patients referred to our syncope clinic, who satisfied the chronic fatigue criteria of the centre for disease control and prevention. Head-up tilt testing induced significant hypotension and increased heart rate in all three patients, consistent with the clinical and autonomic manifestations of postural orthostatic tachycardia syndrome. We report on the emerging evidence available which does suggest a direct relationship between these two syndromes

Correlation of Patient Weight and Cross-Sectional Dimensions with Subjective Image Quality at Standard Dose Abdominal CT

OBJECTIVE: We evaluated the association between patients' weight and abdominal cross-sectional dimensions and CT image quality. MATERIALS AND METHODS: We prospectively evaluated 39 cancer patients aged more than 65 years with multislice CT scan of abdomen. All patients underwent equilibrium phase contrast-enhanced abdominal CT with 4 slices (from top of the right kidney) obtained at standard tube current (240 280 mA). All other scanning parameters were held constant. Patients' weight was measured just prior to the study. Cross-sectional abdominal dimensions such as circumference, area, average anterior abdominal wall fat thickness and, anteroposterior and transverse diameters were measured in all patients. Two subspecialty radiologists reviewed randomized images for overall image quality of abdominal structures using 5-point scale. Non-parametric correlation analysis was performed to determine the association of image quality with patients' weight and cross-sectional abdominal dimensions. RESULTS: A statistically significant negative linear correlation of 0.46, 0.47, 0.47, 0.58, 0.56, 0.54, and 0.56 between patient weight, anterior abdominal fat thickness, anteroposterior and transverse diameter, circumference, cross-sectional area and image quality at standard scanning parameters was found (p< 0.01). CONCLUSION: There is a significant association between image quality, patients' weight and cross-sectional abdominal dimensions. Maximum transverse diameter of the abdomen has the strongest association with subjective image quality.
