Predictive Value of Symptoms for Early Detection of Ovarian Cancer

Recently, an interesting randomized control trial on treatment of advanced ovarian cancer was conducted by Vergote et al. Perez-Medina Abstract In spite of the increased awareness of ovarian cancer symptoms, the predictive value of symptoms remains very low. Adjuvant chemotherapy for early stage ovarian cancer is still controversial but some studies have shown its benefit under confined conditions. Groups of case patients have been population-based samples , , , hospital-based samples , , , , or convenience samples , ,. Psychological and social support for the patient and family, as well as spiritual and existential issues, become central if there is no realistic hope of cure. The specificity was 90% for women 50 years or older and 86. But ovarian cancer is hard to detect early.

These findings suggest that these two different types of ovarian cancers develop along different molecular pathways. It appears that the vast majority of what seem to be primary epithelial ovarian and primary peritoneal carcinomas is, in fact, secondary from the fimbria, the most distal part of the fallopian tube. Several randomized trials have been performed in platinum-sensitive patients. Because early-stage disease accounts for a small proportion of invasive ovarian cancer, data regarding the occurrence of symptoms in this group are limited. As the tumor enlarges, it compresses and eventually obliterates ovarian tissue resulting in an adnexal tumor that appears to have arisen in the ovary. The estimated positive predictive value of the symptoms was 0.

It is often used in conjunction with other modalities such as radiation therapy, surgery etc. Case patients may be more likely than control subjects to recall symptoms, or their recall may be influenced by subsequent health status or treatment. Also, n difference was observed in median progression-free survival. Highly radiosensitive cancer cells are rapidly killed by modest doses of radiation. The occurrence of some symptoms diarrhea or constipation, bloating, and abdominal or pelvic pain rated as severe was also reduced among women with early-stage disease results not shown. Strengths of the current study include its large population-based case group and the use of a structured in-person interview to collect symptom information. This algorithm is most applicable for epithelial ovarian cancer.

Validated tools, such as the Memorial Symptom Assessment Scale, facilitate communication between the patient and care team. In the study, 20 patients 40% responded to the therapy. The deeper knowledge of ovarian cancer biology has led to the identification of multiple molecular targets, such as growth factor receptors, signal transduction pathways, cell cycle regulators, and angiogenic mechanisms. Considering those previous reports, alternative chemotherapy regimens or novel treatment for clear cell and mucinous carcinoma should be investigated. Palliative and end-of-life care for patients with ovarian cancer.

The journal focuses on experimental oncology, clinical oncology and cancer epidemiology and its prevention. This percentage can largely depend on the experience of the surgeon. Advanced disease may present with symptoms of regional spread or metastasis, such as bowel or ureteral obstruction, or shortness of breath. It also includes referral for genetic counseling, if not already made, and counseling about signs, symptoms, and surveillance for recurrence. The main emphasis is on recent scientific developments in all areas related to gynecologic malignancies. Approximately 25% of patients diagnosed with early-stage disease and 75% to 80% of patients with advanced disease experience recurrence within five years.

Journal of Ovarian Research

The search included meta-analyses, randomized controlled trials, clinical trials, and reviews. Also, the duration of symptoms may be shorter among women with advanced-stage disease than among women with early-stage invasive ovarian cancer , although other studies have reported little or no difference in duration of symptoms by stage of invasive disease ,. The imperfect specificity of symptoms for detecting ovarian cancer and the relatively low prevalence of this disease indicate that most women with symptoms will not have ovarian cancer. Journal of Medical Oncology is a peer-reviewed medical Oncology journal dedicated towards cancer research. Known nongenetic risk factors for epithelial ovarian cancers are increased age, postmenopausal hormone therapy particularly for more than five years , and obesity or weight gain.

For example, clear cell carcinoma and mucinous cadenocarcinoma are classified as type I tumors, but unlike the other type I tumors clear cell and mucinous cell types are often high-grade at presentation and show relatively strong resistance to platinum-based chemotherapy. Timmerman D, Ameye L, Fischerova D, et al. After that, care may transition to an annual review of systems and physical examination in primary care.

Clinical Ovarian and Other Gynecologic Cancer

Patients with platinum refractory and resistant are good candidates for novel investigational approaches and studies of drug resistance. They were randomized to receive annual multimodal screening, screening with annual transvaginal ultrasonography alone, or no screening. Thus, it is commonly believed that, at least in these cases chemotherapy can be probably avoided and patients can be advised to undergo clinical and instrumental follow-up. Positive predictive value was calculated by use of external estimates of cancer prevalence. False-positive results often represent ovarian lesions that have a low potential to become a lethal cancer.
