A case of coexistent poorly differentiated adenosquamous carcinoma (glassy cell carcinoma), usual-type adenocarcinoma, and squamous cell carcinoma in situ of the cervix.

Poorly differentiated adenosquamous carcinoma (glassy cell carcinoma) of the cervix is extremely rare, accounting for 1-2% of all cervical cancers. Herein, we report a case with coexistent poorly differentiated adenosquamous carcinoma (glassy cell carcinoma), "usual-type" adenocarcinoma, and squamous cell carcinoma in situ of the cervix. A female patient in her 60 s was referred to our hospital and diagnosed with poorly differentiated adenosquamous carcinoma based on cervical cytology and biopsy. The tumor was classified as clinical stage IB1 cervical cancer following magnetic resonance imaging; radical hysterectomy was performed. Histopathological examination revealed poorly differentiated adenosquamous carcinoma (glassy cell carcinoma), usual-type adenocarcinoma, and squamous cell carcinoma in situ, all coexisting. All carcinoma regions showed identical sizes to high-risk human papillomavirus (HPV) in fragment analysis. The patient is currently alive, without evidence of recurrence, 31 months post surgery. In this case, three different carcinomas coexisted. Fragment analysis of the patient's HPV status suggested that all carcinomas were related to an infection with the same high-risk HPV type. To determine the precise mechanism of tumor development, i.e., whether the tumors were of the mixed or collision type, further studies are needed, including clonal analysis for the loss of heterozygosity pattern.

Substitution of transdermal estradiol during oral estrogen-progestin therapy in postmenopausal women: effects on hypertriglyceridemia.

OBJECTIVE: We investigated effects of changing from oral estrogen to transdermal estradiol on the lipid and lipoprotein profile of postmenopausal women who developed hypertriglyceridemia (serum concentrations exceeding 150 mg/dL) during estrogen-progestin therapy. DESIGN: Sixty-one postmenopausal Japanese women receiving 0.625 mg of conjugated equine estrogen plus 2.5 mg of medroxyprogesterone acetate daily for 12 months had developed serum triglyceride concentrations exceeding 150 mg/dL after 12 months of treatment. Thirty-six of them, chosen randomly for study, were assigned at random to either a group that continued this oral regimen or another that changed to transdermal estradiol while continuing 2.5 mg of oral medroxyprogesterone acetate for the next 3 months (n = 18 for each). Blood lipids were compared between groups. RESULTS: Serum concentrations of triglyceride and very-low-density lipoprotein triglyceride decreased significantly after changing to transdermal estradiol (triglyceride, from 226.0 +/- 43.9 to 110.5 +/- 44.1 mg/dL, P < 0.01). No changes were seen in concentrations of low-density lipoprotein cholesterol or high-density lipoprotein cholesterol. CONCLUSION: Changing to transdermal estradiol may improve triglyceride metabolism in women who developed hypertriglyceridemia during oral estrogen-progestin therapy, with minimal effect on cholesterol profiles.

[Recurrent ovarian cancer with cancer peritonitis treated with weekly paclitaxel infusion--a clinicopharmacological study].

We treated a patient with recurrent ovarian cancer with cancerous peritonitis by weekly paclitaxel (w-TXL) therapy (65 mg/m2). Abdominocentesis was not performed to eliminate ascites, in order to maintain higher quality of life (QOL), and critical adverse reaction was not seen for 12 months. We measured the TXL concentration in blood plasma and ascites after TXL infusion by HPLC method. The TXL titer in plasma was 427 ng/ml after infusion, 23 ng/ml after 24 hours and under 10 ng/ml after 48 hours. The TXL titer in ascites was 41 ng/ml after infusion, 37 ng/ml after 6 hours, 18 ng/ml after 12 hours, 10 ng/ml after 24 hours and under 10 ng/ml after 48 hours. TXL transportation from blood to ascites was good. This result suggested that intravenous infusion of TXL was effective for cancerous peritonitis treatment.

[A case of ovarian cancer with Parkinson's disease treated by combined chemotherapy with paclitaxel and carboplatin followed by surgery].

It is well known that neuropathy, myelopathy, and arthropathy are specific adverse effects induced by paclitaxel administration. Parkinson's disease is neural degenerative disease, and the influence of paclitaxel administration on patients with Parkinson's disease is unknown. We have successfully treated an ovarian cancer patient with Parkinson's disease by paclitaxel/CBDCA combined chemotherapy after surgery. The patient was a 57-year-old woman with solid and cystic ovarian tumor. Among the tumor markers CA125, CA19-9, and SLX, only SLX was elevated. We operated and made a pathological diagnosis of the ovarian tumor as clear cell adenocarcinoma (FIGO stage Ic). After surgery, the patient was treated with paclitaxel (260 mg [175 mg/m2]) and CBDCA (600 mg [AUC = 5]) combined chemotherapy for 5 courses. Her status is complete remission. During chemotherapy, she had felt the decreased efficacy of her Parkinson's disease medication. We could continue chemotherapy by increasing the dose of the Parkinson's drug. There is only one case report on the influence of paclitaxel on Parkinson's disease, in which the course was similar to the present case.
