ABSTRACT
Vulvar lymphatic leakage is a severe complication associated with gynecological cancer treatments. However, standard treatment strategies have not yet been determined. We encountered a rare case of a 76-year-old multiparous woman suffering from massive lymphatic fluid leakage from the entire vulva, and papules developed and were identified as lymphangiomas. A large amount of straw-colored discharge continued from all vulvar papules, which extended over the mons pubis. Nine years ago, the patient had undergone a radical hysterectomy with concurrent chemoradiation for uterine cervical cancer treatment. Her serum albumin level was 1.9 mg/dl, which was attributed to the loss of a large amount of lymph fluid due to leakage from the vulva. Her quality of life gradually decreased because of general fatigue and the need for frequent diaper exchanges every 2 h. The patient received a less-invasive treatment with cryotherapy using liquid nitrogen. She also received a multimodality treatment consisting of the intravenous administration of albumin, massage of the lower limbs and intensive rehabilitation. Cryotherapy was administered once a week for 3 months. Her discharge almost stopped and vulvar lymphangiomas decreased without any major complications. To the best of our knowledge, this is the first case report of massive lymphatic leakage complicated with vulvar lymphangiomas. Additionally, this case may represent the first successful treatment of vulva lymph leakage by cryotherapy without recurrence. Cryotherapy may have the potential to improve the quality of life as a less-invasive treatment for gynecological cancer survivors without serious complications.

BACKGROUND: Although anastrozole (ANA), an aromatase inhibitor (AI), has been widely used for breast cancer patients; adverse events during ANA therapy in Japanese patients have not been reported. METHODS: The study included 656 postmenopausal breast cancer patients receiving ANA as postoperative adjuvant therapy in our hospital. Adverse events during ANA therapy, such as musculoskeletal effects and cerebro- and cardiovascular accidents, were investigated over a 5-year period. The percentage changes in lumbar (L2-4) spine bone mineral density (BMD) were determined in 71 patients receiving ANA alone and 26 patients receiving bisphosphonate in combination with ANA for 7-24 months. RESULTS: The follow-up period ranged from 6 to 60 months (median 23 months). Joint pain, the most common adverse event, was observed in 3.6% (24/656) of the patients. Cerebral infarctions occurred in 0.3% (2/656) of the patients, and no cardiovascular accidents occurred. Bone fractures occurred in nine patients receiving ANA alone. The mean age and BMD of the nine patients were 67.6 years and 71.8% (compared to the young adult mean BMD), respectively. Accumulated and annual fracture rates were 1.3 and 0.8%, respectively. A decrease in BMD was observed in 62.0% (44/71) of the ANA group compared to 26.9% (7/26) of the combination bisphosphonate group (P < 0.01). CONCLUSION: Incidence of adverse events during AI therapy in this Japanese postmenopausal population appears to be lower than that of the ATAC trial. The incidence of bone fractures during AI therapy is lower in Japan, and the addition of bisphosphonates enhances bone health. We should perform a prospective trial in the future to investigate the precise risk of bone fractures in Japanese patients.

ZAC is a paternally expressed, imprinted gene located on chromosome 6q24, within a region known to harbor a tumor suppressor gene for several types of neoplasia, including human ovarian cancer (HOC). We have failed to identify genetic mutations in the ZAC gene in tumor material. Many imprinted genes contain differentially allele-specific-methylated regions (DMR) and harbor promoter activity that is regulated by the DNA methylation. Aberrant DNA methylation is a common feature of neoplasia and changes in DNA methylation at the ZAC locus have been reported in some cases of HOC. We investigated the DNA methylation and ZAC mRNA expression levels in a larger sample of primary HOC material, obtained by laser capture microdissection. ZAC mRNA expression was reduced in the majority of samples and this correlated with hypermethylation of the ZAC-DMR. Treatment of hypermethylated cells lines with a demethylating agent restored ZAC expression. Our studies indicate that transcriptional silencing of ZAC is likely to be caused by DNA methylation in HOC. Forced expression of ZAC resulted in a reduction in proliferation and marked induction of apoptotic cell death. The ZAC-mediated apoptosis signal is p53-independent and eliminated by inhibitors of caspase 3, 8 and 9. Reduced expression of ZAC would therefore favor tumor progression. As there were no significant differences in either DNA methylation or expression of ZAC mRNA between localized and advanced tumors, our data indicates that loss of ZAC is a relatively early event in HOC.
