Ovarian Cancer

Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the U.S. and the fifth most common cause of cancer mortality in U.S. women. Useful biomarkers include cancer antigen 125 (CA 125) and human epididymis protein 4 (HE4).

Clinical Overview

Key Points

Tumor Markers

Markers used in pelvic masses – CA 125 and HE4

Biology

CA 125 – glycoprotein antigen expressed in tissue derived from coelomic epithelial cells (ovary, fallopian tube, peritoneum, pericardium, colorectal, kidney, stomach)
- Frequency of elevation correlates with clinically detected stage of cancer, tumor burden, and type of tumor
HE4 – secreted protein expressed in most epithelial ovarian tumors
- Marker of relapse
- Improves specificity of CA 125 if used in conjunction

Uses

Tumor markers in ovarian cancer and pelvic masses
In general, the combination of CA 125 and HE4 provides the highest sensitivity and specificity

Ovarian Cancer
Screening The U.S. Preventive Services Task Force (USPSTF) and the American Academy of Family Physicians (AAFP) recommend against screening asymptomatic women for ovarian cancer (USPSTF, 2018; Choosing Wisely, 2018) In patients with high-risk factors, CA 125 may be used in conjunction with transvaginal ultrasound and bimanual pelvic examination High-risk factors – family history of ovarian cancer, Lynch syndrome, or linkage to BRCA1 and BRCA2 genotypes
Diagnosis Most ovarian tumors are epithelial and secrete CA 125 and HE4 These markers do not increase early enough to be useful for detecting early stage ovarian cancer (National Comprehensive Cancer Network [NCCN], 2018) In small number of tumors, markers are not expressed Increased survival rates are associated with optimal surgical debulking in initial tumor surgery Best performed at earlier stages Tumor marker panels (American College of Obstetricians and Gynecologists [ACOG], 2017) Insufficient data to recommend for or against use for evaluation of ovarian cancer Recommendations for CA 125 assessment (ACOG, 2017) Cutoffs for referral for ovarian cancer evaluation have poor sensitivity and specificity Mathematical models using rates of change have better positive predictive value Neither cutoffs nor serial CA 125 assessment found to reduce ovarian cancer mortality
Monitoring Markers are useful in monitoring therapy and monitoring for recurrence if CA 125 and/or HE4 level is initially elevated Increasing levels accurately predict relapse
Pelvic Mass
Premenopausal Cannot use markers to differentiate benign from malignant mass False elevations of CA 125 occur in many benign gynecologic diseases (eg, endometriosis) HE4 is more specific – its use alone or in combination with CA 125 is not recommended to rule out malignancy Risk of Ovarian Malignancy Algorithm (ROMA) is useful for assessment of cancer risk in adnexal mass, particularly epithelial cell ovarian cancer Combines CA 125 and HE4, together with menopausal status, to classify patients with adnexal mass into high- or low-risk epithelial ovarian cancer group Can be used to triage patients for appropriate referral Should not be used without an independent clinical radiological evaluation – not intended to be a screening test or to determine whether a patient should proceed to surgery HE4 in combination with CA 125 appears more sensitive than CA 125 alone OVA1 is an alternative to ROMA for preoperative risk stratification for patients with an adnexal mass Combines CA 125, Apo A1, Beta-2 microglobulin, transferrin, and prealbumin into a proprietary multivariate index assay Can be used to triage patients for appropriate referral Should not be used without an independent clinical radiologic evaluation Published studies so far indicate that OVA has a slightly lower positive predictive value, and slightly higher negative predictive value, versus ROMA.
Postmenopausal CA 125 and HE4 are useful in differential diagnosis of pelvic mass Decreased false-positive rate if both tests are performed CA 125 >65 U/mL is highly suggestive of malignancy ROMA – see Premenopausal section above OVA1 – see Premenopausal section above

Ovarian Cancer

Screening

The U.S. Preventive Services Task Force (USPSTF) and the American Academy of Family Physicians (AAFP) recommend against screening asymptomatic women for ovarian cancer (USPSTF, 2018; Choosing Wisely, 2018)
In patients with high-risk factors, CA 125 may be used in conjunction with transvaginal ultrasound and bimanual pelvic examination
- High-risk factors – family history of ovarian cancer, Lynch syndrome, or linkage to BRCA1 and BRCA2 genotypes

Diagnosis

Most ovarian tumors are epithelial and secrete CA 125 and HE4
- These markers do not increase early enough to be useful for detecting early stage ovarian cancer (National Comprehensive Cancer Network [NCCN], 2018)
- In small number of tumors, markers are not expressed
Increased survival rates are associated with optimal surgical debulking in initial tumor surgery
- Best performed at earlier stages
Tumor marker panels (American College of Obstetricians and Gynecologists [ACOG], 2017)
- Insufficient data to recommend for or against use for evaluation of ovarian cancer
Recommendations for CA 125 assessment (ACOG, 2017)
- Cutoffs for referral for ovarian cancer evaluation have poor sensitivity and specificity
- Mathematical models using rates of change have better positive predictive value
- Neither cutoffs nor serial CA 125 assessment found to reduce ovarian cancer mortality

Monitoring

Markers are useful in monitoring therapy and monitoring for recurrence if CA 125 and/or HE4 level is initially elevated
Increasing levels accurately predict relapse

Pelvic Mass

Premenopausal

Cannot use markers to differentiate benign from malignant mass
- False elevations of CA 125 occur in many benign gynecologic diseases (eg, endometriosis)
- HE4 is more specific – its use alone or in combination with CA 125 is not recommended to rule out malignancy
Risk of Ovarian Malignancy Algorithm (ROMA) is useful for assessment of cancer risk in adnexal mass, particularly epithelial cell ovarian cancer
- Combines CA 125 and HE4, together with menopausal status, to classify patients with adnexal mass into high- or low-risk epithelial ovarian cancer group
- Can be used to triage patients for appropriate referral
- Should not be used without an independent clinical radiological evaluation – not intended to be a screening test or to determine whether a patient should proceed to surgery
- HE4 in combination with CA 125 appears more sensitive than CA 125 alone
OVA1 is an alternative to ROMA for preoperative risk stratification for patients with an adnexal mass
- Combines CA 125, Apo A1, Beta-2 microglobulin, transferrin, and prealbumin into a proprietary multivariate index assay
- Can be used to triage patients for appropriate referral
- Should not be used without an independent clinical radiologic evaluation
- Published studies so far indicate that OVA has a slightly lower positive predictive value, and slightly higher negative predictive value, versus ROMA.

Postmenopausal

CA 125 and HE4 are useful in differential diagnosis of pelvic mass
Decreased false-positive rate if both tests are performed
CA 125 >65 U/mL is highly suggestive of malignancy
ROMA – see Premenopausal section above
OVA1 – see Premenopausal section above

Diagnosis

Indications for Testing

Increase in abdominal size or bloating
Pelvic or abdominal pain
Early satiety
Adnexal mass on imaging or bimanual exam

Laboratory Testing

Epithelial cell tumors
- Beta-hCG (β-hCG) – consider this test in premenopausal females to rule out pregnancy
- CA 125
  - Not recommended as a single initial diagnostic test (although results >65 U/mL are highly suggestive of malignancy)
  - Recommended differential diagnosis of suspicious pelvic mass in postmenopausal females
- HE4 – combining with CA 125 decreases false positives
- Inhibin – complements CA 125
  - Best performance in mucinous subtype
- Other markers currently available are not generally as useful
Granulosa-theca cell tumors
- CA 125 – frequently normal (not useful if normal)
- Inhibin – A and B (B usually higher than A)
- Estradiol – often elevated
Germ cell tumors
- CA 125 – not useful (usually normal)
- β-hCG – elevated
- Alpha fetoprotein (AFP) – elevated
- Neuron-specific enolase (NSE) – elevated
- Lactate dehydrogenase (LDH) – elevated

Histology

Surgical biopsy to determine if ovarian mass is malignant (with planned surgical debulking if malignant)
- Avoid percutaneous biopsy – can cause tumor spillage into the pelvis
- All tumors require histologic confirmation for diagnosis

Screening

Routine screening in general population is not currently recommended by the USPSTF (2018) or ACOG (2017)
Trials of screening
- Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial [PLCO] (Buys, 2011)
  - Multimodality screening does not reduce ovarian cancer mortality and can lead to health issues
  - No statistical difference in survival rates between screened and unscreened groups
- United Kingdom Collaborative Trial of Ovarian Cancer Screening [UKCTOCS] – ongoing
  - Evaluating multimodality screening (CA 125 and TVS)
  - Preliminary results indicate multimodality screening has greater specificity and positive predictive value than TVS alone
Screening for specific syndromes
- BRCA – ovarian cancer risk >50%
  - If patient chooses not to undergo total abdominal hysterectomy with bilateral salpingo-oophorectomy, begin screening at age 30
    - See NCCN Genetic/Familial High-Risk Assessment (Breast and Ovarian Cancer) 2018 guidelines
    - Concurrent TVS and CA 125 – every 6 months
      - TVS – preferably day 1-10 of menstrual cycle in premenopausal women
      - CA 125 – preferably after day 5 of menstrual cycle in premenopausal women
- Lynch syndrome (hereditary nonpolyposis colorectal cancer [HNPCC]) – ovarian cancer risk 10%
  - TVS – beginning at 30-35 years (for endometrial cancer screening)
  - CA 125 – unproven efficacy due to inadequate trials
Hereditary breast and ovarian cancer (HBOC) genetic testing recommendations, based on personal and family history (NCCN, 2018)
- Indications for testing in individuals with any of the following
  Indications for testing in individuals with any of the following (NCCN, 2018)
  
  Breast cancer or high-grade prostate cancer diagnosed at any age and Ashkenazi Jewish ancestry
  
  Breast cancer diagnosed by 50 years
  
  Triple-negative breast cancer diagnosed by 60 years
  
  Two breast cancer primaries diagnosed at any age
  
  Breast cancer diagnosed at any age and one or more close blood relatives with breast cancer diagnosed by 50 years, invasive ovarian cancer, male breast cancer, pancreatic cancer, or high-grade or metastatic prostate cancer
  
  Breast cancer diagnosed at any age and two or more close blood relatives with breast cancer at any age
  
  Ovarian cancer, pancreatic cancer, or metastatic prostate cancer diagnosis at any age
  Indications for testing in asymptomatic patient with either of the following
  One or more first- or second-degree relatives with breast cancer diagnosed by 45 years, ovarian cancer, male breast cancer, pancreatic cancer, metastatic prostate cancer, two or more breast cancer primaries in the same family member, or two or more family members with breast cancer primaries on the same side of the family with at least one diagnosed by 50 years

  Perform targeted mutation testing in women with
  - Known pathogenic or likely pathogenic variant in a cancer susceptibility gene within the family
  - Known pathogenic or likely pathogenic variant in a cancer susceptibility gene found on tumor testing

Monitoring

Epithelial
- CA 125
  - Assess patient response to chemotherapy, detect early relapse, and predict prognosis
    - Absolute serum value of CA 125 before third cycle of chemotherapy – most important factor for predicting progression at 12 months
  - Suggested monitoring – every 2-4 months for the first 2 years
    - Persistent postoperative elevation suggests poor prognosis
- HE4
  - Relatively new marker in ovarian cancer monitoring
  - Useful because not all patients with ovarian cancer have elevated CA 125 levels
  - May be complementary when used with CA 125 for monitoring
  - ≥25% change is considered significant
- Inhibin – most useful in monitoring of mucinous subtype tumors
- Other emerging markers, such as osteopontin, show promise but cannot be recommended
Stromal tumors (including granulosa, granulosa-theca, and Sertoli-Leydig tumors)
- Inhibin levels – increased levels parallel tumor recurrence
Germ cell
- AFP, β-hCG, LDH
  - Expect decrease after surgery
  - Increasing levels may signal recurrence

Background

Epidemiology

Incidence
- Ovarian cancer – estimated 22,240 new cases and >14,000 deaths annually in the U.S. (NCCN, 2018)
  - Epithelial subtype – ~90% of malignant tumors (NCCN, 2018)
- Incidence increases with age
  - 50-54 years – 20.4/100,000

  - 75-80 years – 48/100,000
Age – median is 63 years
- 90% of women with ovarian cancer are >40 years
Sex
- Epithelial tumors – exclusively female
- Germ cell tumors (gestational trophoblastic or testicular) and granulosa cell tumors occur in both sexes (M<F)

Familial Genetics

BRCA1 and BRCA2 testing is recommended for all patients with history of ovarian cancer (NCCN, 2018)
TP53 gene mutations (Li-Fraumeni syndrome)
- Present in ~50-80% of ovarian carcinomas
- Correlate with high grade and advanced state
- High-grade serous carcinomas are the most common tumors in this group

Risk Factors

Increased risk associated with
- Family history of breast or ovarian cancer (hereditary breast or ovarian cancer)
  - Associated with BRCA1, BRCA2, and Lynch Syndrome II
    - Higher probability of BRCA1 and BRCA2 gene mutations in Ashkenazi Jews
    - 10-15% of ovarian cancers are caused by BRCA1 or BRCA2 mutations
- Nulliparity
- Older age at first birth (≥35 years)
- Early menarche
- Hormone therapy
- Pelvic inflammatory disease (PID), in vitro stimulation may increase risk
Decreased risk (30-60%) associated with
- Oral contraceptive use
- Pregnancy and first birth at young age (≤25 years)
- Multiparity
- Lactation (>18 months)
- History of tubal ligation/hysterectomy
- Early menopause/late menarche

Pathophysiology

Malignant transformation of Müllerian epithelium on ovarian surface or Müllerian inclusion cysts in ovarian cortex
- Some high-grade serous carcinomas likely represent spread from a primary tumor arising in distal fallopian tube
Often spreads early to contiguous peritoneal mesothelium
- Spread follows flow of peritoneal fluid
Types
- Epithelial
- Stromal
- Germ cell
- Metastases
- Miscellaneous

Clinical Presentation

- Pleural effusions
- Umbilical mass (Sister Mary Joseph nodule)
- Ovarian mass
Unusual findings
- Seborrheic keratoses (Leser-Trélat sign)
- Migratory superficial thrombophlebitis (Trousseau sign)
- Subacute cerebellar degeneration (paraneoplastic syndrome)
- Palmar fasciitis
- Dermatomyositis

Stromal cell tumors

- Juvenile
  - Suspect this tumor in females <20 years with adnexal mass
  - Precocious sexual development in prepubertal female
  - Rare virilization
  - Abdominal pain (predominant symptom)
- Adult
  - Abdominal pain, increasing girth (predominant symptoms)

Prevention

In patients with known BRCA1 or BRCA2 gene mutation who have completed childbearing, bilateral salpingo-oophorectomy dramatically reduces risk for tubo-ovarian cancer

Small risk will still exist for primary peritoneal serous carcinoma

ARUP Lab Tests
