ABSTRACT

The pleural cavity constitutes the most frequent extra-abdominal metastatic site in ovarian carcinoma (OC). In patients with OC and pleural effusions, a positive fluid cytology is required for a stage IV diagnosis. Unfortunately, about 30% of malignant pleural effusions exhibit false negative cytological pleural fluid results. In those circumstances, exploratory video-assisted thoracoscopic surgery (VATS) serves as a diagnostic, staging and even therapeutic modality. Maximal (no visible disease) or, at least, optimal (no residual implant greater than 1 cm) cytoreduction should be the primary surgical goal in stage IV OC patients. This is due to residual tumor after cytoreductive surgery being one of the most important factors impacting on survival. Although malignant pleural effusions do not preclude abdominal surgical debulking, excision of gross pleural nodules may be necessary to achieve optimal cytoreduction. VATS quantifies pleural tumor burden and allows for intrathoracic cytoreduction or, if the latter is not feasible, ensures that abdominal surgery is not unnecessarily performed on women in whom gross tumor would still remain in the pleural space afterwards. Taxane-platinum neoadjuvant chemotherapy should be offered to this group. Patients with tumor extension into the pleural space have a median overall survival of 2 years.

In most women with ovarian carcinoma, the disease is not diagnosed until it is at an advanced stage. Primary cytoreductive surgery is considered the standard of care for advanced ovarian carcinoma.1-4 However, data from prospective, randomized, controlled trials assessing the role of primary surgery in the treatment of such cases are lacking. Interval debulking surgery has not been viewed as beneficial in women with residual tumor that exceeds 1 cm in diameter after primary debulking surgery performed with the objective of maximal surgical effort by a gynecologic oncologist.5-7 As an alternative to primary debulking surgery followed by chemotherapy, some authors have investigated the use of neoadjuvant chemotherapy before cytoreductive surgery. However, results of a meta-analysis involving 835 patients suggested that neoadjuvant chemotherapy, as compared with primary debulking surgery, was associated with a worse outcome.8
We report on a randomized trial in which we compared primary debulking surgery followed by platinum-based chemotherapy and platinum-based neoadjuvant chemotherapy followed by interval debulking surgery and additional platinum-based chemotherapy in women with advanced ovarian carcinoma.............

Note:

1) see Section 2.3 for study criteria (patient enrollment requirements);
2) .... acquisition of tumour specimens both before study therapy is started and after neoadjuvant chemotherapy has been received provides a unique opportunity for a correlative study of differing drug responses within the same patients.

Although the study is led by the ncic ctg, the protocol, the accompanying IP therapy guidelines, and a companion document intended to summarize and promote best practice in the administration of IP therapy are the result of a collaboration between the ncic ctg and the Society of Gynecologic Oncologists of Canada, with international partners in the United Kingdom (National Cancer Research Institute), Spain (Spanish Ovarian Cancer Research Group), and the United States (Southwest Oncology Group).

Scleroderma-like cutaneous lesions induced by paclitaxel and carboplatin for ovarian carcinoma, not a single course of carboplatin, but re-induced and worsened by previously administrated paclitaxel (Taxol)

"ABSTRACT

Scleroderma-like cutaneous lesion as an adverse event from paclitaxel and carboplatin has been reported. No report shows the occurrence of scleroderma-like cutaneous lesions from a single course of carboplatin. The patient is a 67-year-old female, administered paclitaxel and carboplatin as neoadjuvant chemotherapy. Following four courses, scleroderma-like cutaneous lesions were demonstrated. Skin biopsy corresponded to histopathological findings of scleroderma. Immunological investigation shows only antinuclear antibodies are positive. The characteristic Raynaud's phenomenon of scleroderma and hemorrhagic spots on the cuticles were not found. Postoperatively, a single course of carboplatin treatment was given. Scleroderma-like cutaneous lesions re-induced and worsened. This is the first report detailing scleroderma-like cutaneous lesions induced by previously administrated paclitaxel that worsened by carboplatin."

OBJECTIVE: To evaluate drug resistance after exposure to neoadjuvant chemotherapy and to postoperative chemotherapy in epithelial ovarian, fallopian, and primary peritoneal carcinomas.
