Metastatic Tumors of Ovary
METASTATIC TUMOR FROM BREAST CANCERboth ovaries replaced by pale, rather nodular tumor, with breast cancer cells arranged in long lines perpendicular to the surface of the ovarian cortex
METASTATIC TUMOR FROM GASTRIC CANCER (Krukenberg )
gastric carcinoma of the fundus, with secondary ovarian tumor (Mucus-secreting signet-ring cells)Krukenberg Tumor:
Neoplastic Ovarian TumoursSurface epithelial – 65-70% Germ cell tumors – 15-20% stromal – 10-15%Metastatic tumors – 5%
Epidemiology
15,900 deaths annually 4th common cause of cancer mortality Most (70%) diagnosed at advanced stage where cure is uncommon. 23,000 cases annually Ranks 3rd among gynecologic cancers Ranks 5th among women cancers.Risk Factors
Personal H : Any age ( common >40ys) . Nulliparous. Late age 1st preg History of breast or colon cancer. Gonadal Dysgenesis Talcum powder Increased risk in women who use talc powder on genital area
Risk Factors
M.H: Early menarche. Late menopause prolonged use of fertility drugs without achieving pregnancy Hormone replacement therapy > 10 years Uninterrupted ovulation. F.H Mother, sister or daughter with ovarian cancer.Protective factors
Multiparity: First pregnancy before age 30 Oral contraceptives. Hysterectomy Lactation Bilateral oopherectomycomplications of benign ov Tumours

HistoryExam (including rectal)Investigations:-TVS –masses and mass characteristicsTumor markers – CA-125, LPA (plasma lysophosphatidic acid)CT – assess spread to LN, pelvic and abdominal structuresMRI – best for distinguishing malignant from benign tumorsClinical picture of benign ov tumors
Symptoms: functioning tumors nonfunctioning tumors swelling pressure symptoms pain menstrual disturbances ovarian cachexia Signs small ov tumors large ov tumors DD: from other pelvic swellings from other abdominal swellingsClinical picture cancer ovary
Benign ovarian Tumours + The following suggest malignancy age:mostly postmenopausal pain: chronic and persistent rapid course bilaterality Solidity ( variegated consistency ) fixity metastases :nodules in DP, lymph nodes ascitis edema LL cachexiaStaging:
Vertical incision.Aspirate, or saline washing.Careful assessment., Liver, rt hemidaphragm, All other organs as omentum, intestine,….Para aortic LN sampling.Proper staging, for prognosis, selection of adjuvant therapy…..Ovarian Cancer Staging
Stage 1 1A: One ovary 1B: Both ovaries 1C: with malignant ascites, rupture surface tumorOvarian Cancer Staging
Stage 2 2A: Reproductive organs 2B: Other pelvic organs 2C: with malignant ascites or washingsOvarian Cancer Staging
Stage 3 3A: microscopic upper abdominal disease 3B: upper abdominal metastasis less than 2 centimeters 3C: upper abdominal metastasis greater than 2 centimetersOvarian Cancer Staging
Stage 4 is disease outside the peritoneal cavity Liver parenchymal metastasis. Pleural effusion Supraclavicular nodesTreatment
Depends on Staging Tumor type Age Desire for future fertility Include surgery, chemotherapy and/or radiation therapySurgery for ov. cancer Complete surgery:TAH/BSO +omentectomy+lymphadenectomy other cases of stage Ia Conservative surgery: unilateral adnexectomy indicated: stage Ia: intact capsule, negative peritoneal washing, free omentum, well differentiated T, young patient with low parity Stage Ib,c
Surgery for ov. Cancer cont… Cytoreductive surgery: for all other stages optimum cytoreduction leaving no macroscopic lesion or one less than 1.5 cm. consist of TAH/BSO +omentectomy+lymphadenectomy+may be bowel resection & anastmosis.
Second look surgery after chemotherapy
Surgical treatmentPrimary debulking and cytoreduction; may include:Bilateral salpingo-oopherectomyHysterectomyLymphadenectomy (Para-aortic, inguinal)Omentectomy“brushing” of diaphragmExamination of liver
Chemotherapy & radiotherapy for ov cancer
Chemotherapy: adjuvant to surgery to improve prognosis in early stages induce remission in advanced cases agents: alkylating agents,platinum: single drug and multible drug regimensChemotherapy & radiotherapy for ov cancer cont……… Radiotherapy: has less place in modern practice, replaced by chemotherapy was given for cases with small residual lesions (< 2 cm) forms are: radioactive isotope: intraperitoneal 32P , external-beam radiotherapy
