Phase II study of gemcitabine, cisplatin, and bevacizumab for first recurrent and refractory ovarian clear cell carcinoma Kansai Clinical Oncology Group-G1601.

Patients with advanced ovarian clear cell carcinoma (CCC) have a poor prognosis in the absence of an effective standard treatment. Combination therapy with gemcitabine, cisplatin, and bevacizumab (GPBev) is promising for ovarian CCC. Thus, we conducted a multi-institutional, phase II trial in Japan to examine the efficacy and safety of GPBev for CCC.

[Clinical Application of Gemcitabine plus Cisplatin plus Bevacizumab Combination Chemotherapy for Ovarian Clear Cell Carcinoma].

Ovarian clear cell carcinoma(OCCC)shows a poor response to standard chemotherapy, and it is often difficult to choose a regimen for patients with recurrent OCCC. Several reports have suggested a synergistic effect between gemcitabine and cisplatin; another report suggested that gemcitabine, platinum, and bevacizumab are efficacious against recurrent ovarian cancer. We treated patients with OCCC using a combination chemotherapy regimen consisting of gemcitabine(1,000 mg/ m2)and cisplatin(40 mg/m2)on days 1 and 15, and bevacizumab(15 mg/kg)on day 1, with the cycle repeated every 4 weeks.

A case in which laparoscopic right salpingo-oophorectomy was performed in a patient with a lumboperitoneal shunt.

Introduction: Ventriculoperitoneal (VP shunts) and lumboperitoneal shunts (LP shunts) are used to treat hydrocephalus. The effectiveness of LP shunts has recently been demonstrated. Due to population aging, the number of patients with LP shunts is expected to increase.

[A Retrospective Analysis of Systematic Lymphadenectomy for Loco-Regional(pT1)Epithelial Ovarian Cancer].

Background: The incidence of lymph node metastasis in pT1 epithelial ovarian cancer is between 5% and 21%. Most cases with lymph node metastasis are those of serous carcinoma; it is relatively rare in mucinous carcinoma. Therefore, there is a recent trend to omit systematic lymphadenectomy in early stage mucinous carcinoma.

[Comparison between Primary Debulking Surgery and Neo-Adjuvant Chemotherapy Followed by Interval Debulking Surgery for Patients with Stage III-IV Ovarian Cancer].

The current standard treatment for advanced ovarian cancer is primary debulking surgery(PDS). We may expect a good prognosis if complete debulking(no visible residual tumor)is possible. However, if complete surgery is not possible owing to the location of the tumor or poor performance status, neo-adjuvant chemotherapy(NAC)could be an alternative option.

[A Retrospective Case Study of Combination Chemotherapy with Bevacizumab for Recurrent Ovarian Cancer].

Objectives: Treatment for ovarian cancer with bevacizumab(Bmab)has been covered by public medical insurance in Japan since November 2013. It is recommended that the use of Bmab is limited to the first treatment for FIGO stage III or IV ovarian cancer. The OCEAN trial for platinum sensitivity in relapsed patients and the AURELIA trial for platinum-resistance in relapsed patients were performed, and both significantly improved progression-free survival.

[A Case of Bilateral Pneumothorax after Chemotherapy for Uterine Leiomyosarcoma with Multiple Lung Metastases].

We encountered a case of uterine leiomyosarcoma with multiple lung metastases. The patient was a 52-year-old woman who underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy followed by chemotherapy with gemcitabine and docetaxel. After 1 cycle of chemotherapy, the lung metastasis was reduced, but at the same time, she developed bilateral pneumothorax.

[A Case of Pneumocystis Pneumonia during Chemotherapy for Recurrent Ovarian Cancer].

A 53-year-old patient with recurrent ovarian clear cell adenocarcinoma developed fever (39°C) and cough on day 28 of liposomal doxorubicin chemotherapy, the 4th cycle of the 4th regimen since initial treatment. Drug-induced interstitial pneumonia was suspected from a chest CT image showing diffuse ground-glass opacities; however, we deduced pneumocystis pneumonia from the elevated serum beta-D-glucan levels. After effective treatment with sulfamethoxazole and amphotericin B, the patient's symptoms and radiological findings improved.

[A case of stage IV rectal cancer with whom EPA oral nutritional supplements could resolve cachectic condition and promote patient compliance with cancer chemotherapy].

We report a case of a Stage IV rectal cancer patient for whom EPA oral nutritional supplements promoted treatment compliance with cancer chemotherapy by resolving a refractory cachectic condition. A 76-year-old male who developed a local re-growth of residual disease and multiple lung metastases after abdomino-perineal resection for lower rectal cancer was referred to our clinic for chemotherapy. On admission, he suffered from a loss of appetite as well as a 30% loss of usual body weight, caused by a cachectic condition with systemic inflammatory response.
