Recent reports showed that bevacizumab, a humanized recombinant antibody binding to vascular endothelial growth factor (VEGF), harbored a significant activity in advanced or recurrent epithelial ovarian cancers. However, life-threatening complications including arterial thrombosis, pulmonary hemorrhage, and gastrointestinal perforation (GIP) are not negligible. A Japanese case of bowel perforation associated with bevacizumab treatment in heavily pretreated ovarian cancers is reported. The case affected with refractory ovarian cancer had no signs of bowel obstruction and bowel thickness which are now recognized as risk factors of GIP associated with bevacizumab. After obtaining a written informed consent, a combination of weekly paclitaxel and weekly bevacizumab was administered as the fourth-line therapy. After nine cycles of the regimen, the case developed GIP, although the recurrent tumor showed a stable disease. After conservative therapy for two months, the patient died. The case was severely pretreated; however, there seemed to be no risk factors for GIP. Therefore, we do recommend that special cautions are required for the bevacizumab- based chemotherapy, especially severely pretreated ovarian cancer patients.

Ovarian cancer is the second most common gynecologic cancer in women and the leading cause of death caused by gynecologic malignancy. Surgery plays a fundamental role in treating this challenging disease. Goals of primary surgery for ovarian cancer are to establish diagnosis, proper staging, determination of prognosis, and optimal cytoreduction of gross disease before chemotherapy for improved outcome. In addition to standard removal of the ovaries, uterus, omentum, and pelvic and para-aortic lymph nodes for early disease, extended surgical techniques used to debulk advanced disease include bowel resection, splenectomy, partial liver resection, peritoneal or diaphragmatic stripping, and use of laser or ultrasound (CUSA). Secondary surgery is used in a variety of situations. Second-look procedures were performed historically to determine response to chemotherapy to delineate duration of treatment, but now are best used in a research setting with the advent of improved chemotherapeutic agents. As a high percentage of patients have a gynecologic malignancy recurrence after primary treatment, many practitioners perform secondary cytoreductive procedures for recurrent disease. Additionally, in the recurrent setting, surgery may be necessary for relief of bowel obstruction and palliation of symptoms. Surgical management of ovarian cancer must be performed by surgeons, such as gynecologic oncologists, who have a firm understanding of the disease process, display good clinical judgment, and are adequately trained to perform the complex surgery that commonly is required for appropriate care.

We report a 35-year-old female bearing ovarian cancer who was suffering from intestinal obstruction due to multiple recurrences. The treatment of 300 microg/day of octreotide acetate was started. The symptom of obstruction, such as vomiting and nausea, caused by intestinal obstruction was suddenly controlled and the quality of life was improved. Octreotide acetate can be applied for the management of intestinal obstruction caused by metastases at the terminal stage of cancer.

The biology of ovarian carcinoma differs from that of hematogenously metastasizing tumors because ovarian cancer cells primarily disseminate within the peritoneal cavity and are only superficially invasive. However, since the rapidly proliferating tumors compress visceral organs and are only temporarily chemosensitive, ovarian carcinoma is a deadly disease, with a cure rate of only 30%. There are a number of genetic and epigenetic changes that lead to ovarian carcinoma cell transformation. Ovarian carcinoma could originate from any of three potential sites: the surfaces of the ovary, the fallopian tube, or the mesothelium-lined peritoneal cavity. Ovarian cacinoma tumorigenesis then either progresses along a stepwise mutation process from a slow growing borderline tumor to a well-differentiated carcinoma (type I) or involves a genetically unstable high-grade serous carcinoma that metastasizes rapidly (type II). During initial tumorigenesis, ovarian carcinoma cells undergo an epithelial-to-mesenchymal transition, which involves a change in cadherin and integrin expression and up-regulation of proteolytic pathways. Carried by the peritoneal fluid, cancer cell spheroids overcome anoikis and attach preferentially on the abdominal peritoneum or omentum, where the cancer cells revert to their epithelial phenotype. The initial steps of metastasis are regulated by a controlled interaction of adhesion receptors and proteases, and late metastasis is characterized by the oncogene-driven fast growth of tumor nodules on mesothelium covered surfaces, causing ascites, bowel obstruction, and tumor cachexia.

A palliative care team provides palliative care in the hospital setting.However, palliative care might be discontinued when a patient was switched to an outpatient from an inpatient or when a patient was being transferred to another hospital.In the present work, we report a case who could receive anti-cancer therapy and palliative care simultaneously at home.The case is a 46-year-old woman.She was diagnosed as left ovary cancer in 1990's and underwent an operation followed by chemotherapy. The tumor relapsed and invaded the sigmoid colon in 2000's.She then developed an intestinal obstruction and was hospitalized.After her conditions were stabilized, she was discharged but still needed a high degree of medical interventions. She was introduced to another hospital providing a home palliative care as well as emergency admission.She could fulfill her desire to receive a palliative care and chemotherapy simultaneously at home through this seamless healthcare linkage.It should be insisted that hospital oncologists and home doctors need to acquire the knowledge of palliative care and close cooperation between them is required.It is also important to establish a comprehensive healthcare linkage system in the society.

Surgical management of ovarian cancer requires excellent judgment and mastery of a wide array of procedures. Involvement of a gynecologic oncologist improves outcomes. Staging of apparent stage I disease is important. Minimally invasive techniques provide advantages. Primary debulking surgery provides the best long-term survival of any strategy in advanced ovarian cancer. Aggressive surgical paradigms have the greatest success. Further cytoreductive surgery may be appropriate. Most relapsed patients require management of bowel obstruction at some point. Palliative intervention can enhance quality of life. Surgical correction may extend survival. For end-stage patients with progressive disease, the treating gynecologic oncologist must manage expectations.

Background. Abdominal cocoon, or sclerosing encapsulating peritonitis, is a rare condition characterized by partial or total encasement of small bowel and mesentery by a thick fibrocollagenous sack that looks like a cocoon. Within the sack, bowel loops are drawn together causing intestinal obstruction.Case presentation. We report on a 57-year-old female patient who developed a very unusual complication of ovarian cancer: abdominal cocoon formation.Conclusions. This report highlights the need for a timely diagnosis of sclerosing encapsulating peritonitis in cancer patients.

We report the first documented case of ovarian metastasis from a jejunal primary adenocarcinoma in an Australian patient. The presentation was unusual, initially a suspicious abdominal nodule in the epigastric area, which turned out to be an adenocarcinoma of possible intestinal origin. Gastroscopy and colonoscopy were performed with no suspicious lesion identified. Abdominal and pelvic ultrasound imaging showed a complex pelvic mass suspicious of ovarian cancer. Laparoscopy was performed to exclude possibility of ovarian cancer and small bowel cancer. The ovarian mass showed similar features from the epigastric nodule, again suggestive of intestinal primary. Definitive diagnosis was obtained when the patient represented 2 months later with malignant bowel obstruction requiring palliative resection of the proximal jejunum. This case demonstrates the difficulty in diagnosing ovarian metastasis from a small bowel primary, which has the potential to mimic an ovarian primary tumour clinically, and a large bowel or ovarian primary pathologically.

Bowel obstruction resulting from colorectal and ovarian cancer is a serious and distressing complication of these malignancies. This may be caused by diffuse peritoneal carcinomatosis, bulky masses filling the pelvis and abdomen or postoperative adhesions, and should be carefully worked out by pre-operative imaging. We report the case of a small bowel obstruction and intestinal ischemia caused by a bulky (20x40 cm in diameter) cystic ovarian neoplasm that was found to be a stage IA G2 cystadenocarcinoma, successfully managed by uterus-sparing surgery.

We sought to report incidence, risk factors, and survival related to bowel obstruction in 311 ovarian cancer patients with recurrent disease. A total of 68 (22%) had a documented bowel obstruction during their cancer course, and 49 (16%) developed it after cancer recurrence. Surprisingly, 142 (45%) fit into an "unknown" category (3+ months of data lacking from last contact/death). No risk factors were identified; management included surgery (n = 21), conservative measures (n = 21), and other (n = 7). Documented bowel obstruction was not associated with a statistically significant reduction in survival after cancer recurrence. In conclusion, although bowel obstruction occurs in only a subgroup of patients with ovarian cancer and does not appear to detract from survival after cancer recurrence, limited end-of-life information may be resulting in an underestimation of incidence.
