Frequency of Symptoms of Ovarian Cancer in Women Presenting to Primary Care Clinics

Abstract: ContextWomen with ovarian cancer frequently report symptoms prior to diagnosis, but distinguishing these symptoms from those that normally occur in women remains problematic.ObjectiveTo compare the frequency, severity, and duration of symptoms between women with ovarian cancer and women presenting to primary care clinics.Design, Setting, and PatientsA prospective case-control study of women who visited 2 primary care clinics (N = 1709) and completed an anonymous survey of symptoms experienced over the past year (July 2001-January 2002). Severity of symptoms was rated on a 5-point scale, duration was recorded, and frequency was indicated as number of episodes per month. An identical survey was administered preoperatively to 128 women with a pelvic mass (84 benign and 44 malignant).Main Outcome MeasuresComparison of self-reported symptoms between ovarian cancer patients and women seeking care in primary care clinics.ResultsIn the clinic population, 72% of women had recurring symptoms with a median number of 2 symptoms. The most common were back pain (45%), fatigue (34%), bloating (27%), constipation (24%), abdominal pain (22%), and urinary symptoms (16%). Comparing ovarian cancer cases to clinic controls resulted in an odds ratio of 7.4 (95% confidence interval [CI], 3.8-14.2) for increased abdominal size; 3.6 (95% CI, 1.8-7.0) for bloating; 2.5 (95% CI, 1.3-4.8) for urinary urgency; and 2.2 (95% CI, 1.2-3.9) for pelvic pain. Women with malignant masses typically experienced symptoms 20 to 30 times per month and had significantly more symptoms of higher severity and more recent onset than women with benign masses or controls. The combination of bloating, increased abdominal size, and urinary symptoms was found in 43% of those with cancer but in only 8% of those presenting to primary care clinics.ConclusionsSymptoms that are more severe or frequent than expected and of recent onset warrant further diagnostic investigation because they are more likely to be associated with both benign and malignant ovarian masses.

Development of an ovarian cancer symptom index

Abstract: BACKGROUND. Currently, screening for ovarian cancer is not recommended for the general population. Targeting women with specific symptoms for screening has been evaluated only recently, because it was believed that symptoms had limited specificity. METHODS. A case-control study of 149 women with ovarian cancer, including 255 women who were in a screening program and 233 women who were referred for pelvic/abdominal ultrasound, was conducted by inviting women to complete a survey of symptoms. Patients were divided randomly into an exploratory group and a confirmatory group. Symptom types, frequency, severity, and duration were compared between cases and controls. Logistic regression analyses were used to determine which factors independently predicted cancer in the exploratory group and then were used to develop a symptom index, which was tested for sensitivity and specificity in the confirmatory group. RESULTS. Symptoms that were associated significantly with ovarian cancer were pelvic/abdominal pain, urinary urgency/frequency, increased abdominal size/bloating, and difficulty eating/feeling full when they were present for 12 days per month. In a logistic regression analysis, symptoms that were associated independently with cancer were pelvic/abdominal pain (P 12 times per month but were present for 50 years and 86.7% for women age <50 years. CONCLUSIONS. Specific symptoms in conjunction with their frequency and duration were useful in identifying women with ovarian cancer. A symptom index may be useful for identifying women who are at risk. Cancer 2007. © 2006 American Cancer Society.

Harrison's Principles of Internal Medicine

Abstract: The 11th edition of Harrison's Principles of Internal Medicine welcomes Anthony Fauci to its editorial staff, in addition to more than 85 new contributors. While the organization of the book is similar to previous editions, major emphasis has been placed on disorders that affect multiple organ systems. Important advances in genetics, immunology, and oncology are emphasized. Many chapters of the book have been rewritten and describe major advances in internal medicine. Subjects that received only a paragraph or two of attention in previous editions are now covered in entire chapters. Among the chapters that have been extensively revised are the chapters on infections in the compromised host, on skin rashes in infections, on many of the viral infections, including cytomegalovirus and Epstein-Barr virus, on sexually transmitted diseases, on diabetes mellitus, on disorders of bone and mineral metabolism, and on lymphadenopathy and splenomegaly. The major revisions in these chapters and many

Ovarian cancer statistics, 2018.

Abstract: In 2018, there will be approximately 22,240 new cases of ovarian cancer diagnosed and 14,070 ovarian cancer deaths in the United States. Herein, the American Cancer Society provides an overview of ovarian cancer occurrence based on incidence data from nationwide population-based cancer registries and mortality data from the National Center for Health Statistics. The status of early detection strategies is also reviewed. In the United States, the overall ovarian cancer incidence rate declined from 1985 (16.6 per 100,000) to 2014 (11.8 per 100,000) by 29% and the mortality rate declined between 1976 (10.0 per 100,000) and 2015 (6.7 per 100,000) by 33%. Ovarian cancer encompasses a heterogenous group of malignancies that vary in etiology, molecular biology, and numerous other characteristics. Ninety percent of ovarian cancers are epithelial, the most common being serous carcinoma, for which incidence is highest in non-Hispanic whites (NHWs) (5.2 per 100,000) and lowest in non-Hispanic blacks (NHBs) and Asians/Pacific Islanders (APIs) (3.4 per 100,000). Notably, however, APIs have the highest incidence of endometrioid and clear cell carcinomas, which occur at younger ages and help explain comparable epithelial cancer incidence for APIs and NHWs younger than 55 years. Most serous carcinomas are diagnosed at stage III (51%) or IV (29%), for which the 5-year cause-specific survival for patients diagnosed during 2007 through 2013 was 42% and 26%, respectively. For all stages of epithelial cancer combined, 5-year survival is highest in APIs (57%) and lowest in NHBs (35%), who have the lowest survival for almost every stage of diagnosis across cancer subtypes. Moreover, survival has plateaued in NHBs for decades despite increasing in NHWs, from 40% for cases diagnosed during 1992 through 1994 to 47% during 2007 through 2013. Progress in reducing ovarian cancer incidence and mortality can be accelerated by reducing racial disparities and furthering knowledge of etiology and tumorigenesis to facilitate strategies for prevention and early detection.

A global assessment tool for evaluation of intraoperative laparoscopic skills

Abstract: Background There is a pressing need for an intraoperative assessment tool that meets high standards of reliability and validity to use as an outcome measure for different training strategies. The aim of this study was to develop a tool specific for laparoscopic skills and to evaluate its reliability and validity. Methods The Global Operative Assessment of Laparoscopic Skills (GOALS) consists of a 5-item global rating scale. A 10-item checklist and 2 visual analogue scales (VAS) for competence and case difficulty were also used. During laparoscopic cholecystectomy, 21 participants were evaluated by the attending surgeon, by 2 trained observers and by self-assessment while dissecting the gallbladder from the liver bed. Results The intraclass correlation coefficient (ICC) for the total GOALS score was .89 (95% confidence interval [CI] .74 to .95) between observers, .82 (95% CI .67 to .92) between observers and attending surgeons, and .70 (95% CI .37 to .87) between participants and attending surgeons. The ICCs (observers) for the VAS (competence) and the checklist were .69 and .70, respectively. The mean total GOALS score (observers) for novices (postgraduate years [PGYs] 1 through 3) was 13 (95% CI 10.3 to 15.7) compared with 19.4 (95% CI 17.2 to 21.5) for experienced (PGY 4 through attending surgeons, P = .0006). The VAS demonstrated a difference in scores between novice and experienced participants ( P = .001); however, the task checklist did not ( P = .09). Conclusions These data indicate that GOALS is feasible, reliable, and valid. They also suggest that it is superior to the task checklist and VAS for evaluation of technical skill by experienced raters. The findings support the use of GOALS in the training and evaluation of laparoscopic skills.
