Does the progression-free interval after primary chemotherapy predict survival after salvage chemotherapy in advanced and recurrent endometrial cancer?

Treatment of Advanced or Recurrent Endometrial Carcinoma with Doxorubicin in Patients Progressing after Paclitaxel/Carboplatin: Memorial Sloan-Kettering Cancer Center (MSKCC) Experience from 1995-2009
Following Institutional Review Board approval, patients with stage I-IV endometrial carcinoma who had received adjuvant TC at MSKCC between 1995 and 2009 were identified
Seventeen patients were included in study analyses. The median PFS from completion of paclitaxel/carboplatin was 8.0 months (95% CI: 4.5-13.6 months). At the time of recurrence, all 17 patients were treated with doxorubicin as second-line therapy. No patient achieved objective response of stable disease. The median PFS of this cohort following doxorubicin treatment was 2.1 months (95% CI: 0.95-2.7) months. Median OS was 5.8 months (95% CI: 1.0-15.0 months). There is only one patient still alive; her median follow-up time is 49.4 months.

Phase III Trial of Doxorubicin With or Without Cisplatin in Advanced Endometrial Carcinoma
Patients were to have histologically documented stage III, IV, or recurrent endometrial carcinoma after prior surgery and/or radiotherapy. Disease was to be measurable and patients were to have had no prior cytotoxic chemotherapy (although they may have been treated with hormonal or one prior biologic therapy)
Overall survival is shown in Fig 2. Overall survival for each regimen was similar, with a median of 9.0 months for the combination arm versus 9.2 months for the single-agent arm. http://ascopubs.org/doi/full/10.1200/jco.2004.02.088
Es gibt eine Menge an Möglichkeiten die das OS beinflussen!
Auch Disease was to be measurable.
Und wie kann eine 2 Fach Chemo ein geringeres OS aufweisen? :-)
