Patient: On November 19, 2008, gynecological examination revealed a large cystic abdominal mass from the adnexa, up to the subxiphoid process, down to the suprapubic area, left and right sides to the anterior axillary line, depth of about 113mm, with poor penetration depth, and strong echogenic bands were visible. The operation was to remove the whole uterus + double adnexa + greater omentum + appendix + abdominal lymph nodes, the result of rapid sectioning during the operation was mucinous junctional tumor, and the postoperative report was mucinous adenocarcinoma of the left ovary I, and no cancerous tissue was found in the whole uterus + double adnexa + greater omentum + appendix + abdominal lymph nodes. I need two help. 1, do I need chemotherapy after the surgery? 2.What kind of medication do I need to use for such a big surgery and I am still young? Whether menstruation is regular or not: Age of first menstruation: Days of each menstrual period: Average number of days of menstrual cycle: Menstrual volume, color, and abdominal pain: Date and status of last menstruation: Age of marriage: Number of pregnancies: Number of miscarriages: Number of births: Doctors: Stages 1-2 are early stage cancers. If there are the following high-risk factors, the recurrence rate is as high as 30%-50%. Therefore, the high-risk group must undergo postoperative adjuvant chemotherapy. High risk factors are as follows: 1) low to medium differentiated carcinoma; 2) rupture of the membrane; 3) tumor tissue on the surface of the ovary; 4) severe adhesion between the tumor and the surrounding area; 5) positive cytology of the abdominal lavage fluid; 6) clear cell carcinoma; 7) stage 1 or stage 2 epithelial carcinoma invading outside the ovary. Your pathology is epithelial carcinoma. You should revisit your medical record before doing an analysis.
