In a private practice setting, 16 patients with advanced or recurrent endometrial carcinoma received cisplatinum 50 mg/m2, doxorubicin 50 mg/m2, and cyclophosphamide 750 mg/m2 every three weeks. Growth factor support using filgrastim was initiated on the first cycle of therapy and each subsequent cycle. Sixteen patients were entered into the study with 13 being evaluable. No patient had previously received chemotherapy. The overall response rate was 54% with two complete responses (15%) and five partial responses (38%). Stable disease was seen in 46% of patients. Progression-free survival was observed to be a median of 8.5 months for a complete response, a median of 8.5 months for a partial response and a median of 7 months for stable disease. Fifteen percent of the patients and 3% of all chemotherapy cycles had febrile neutropenic events. There were no deaths due to myelotoxicity. Only one patient required a dose reduction due to neutropenia. Four of the 13 patients required dose reductions due to previous nadir thrombocytopenia. Grade 4 granulocytopenia occurred in 28% of treatment cycles and grade 3 granulocytopenia occurred in 12% of treatment cycles. The use of filgrastim (G-CSF) allowed patients to stay on therapy for an average of seven treatments. Neutropenia was not the dose-limiting toxicity from this dose-intense regimen.

Doxorubicin, platinum compounds, and taxanes represent the chemotherapeutic agents with the greatest activity in endometrial cancer. We conducted an optimal-dose determination of combination chemotherapy consisting of paclitaxel (TXL), doxorubicin, and carboplatin (CBDCA) (TAC) in patients with endometrial cancer. Patients with epithelial endometrial cancer requiring adjuvant therapy were enrolled between June 2003 and March 2005. No patients had received prior radiotherapy, and only two patients had previously undergone chemotherapy. Doxorubicin was infused on day 1, and TXL followed by CBDCA was administered on day 2. The starting dose was doxorubicin 35 mg/m(2), TXL 120 mg/m(2), and CBDCA area under the curve (AUC). The dose of each agent was gradually escalated. Patients were scheduled to receive at least four cycles of therapy. If patients experienced grade 4 neutropenia or neutropenic fever with grade 3 neutropenia, they were permitted to be administered granulocyte colony-stimulating factor after the second course. Twenty-seven patients were enrolled. Although four patients out of 27 experienced dose-limiting toxicities, a maximum tolerated dose was not established at the final dose level. Five patients (three for recurrent and two for advanced) had measurable lesions. There were four responders (three for partial response and one for complete response) in our series. The recommended dose of TAC therapy for endometrial cancer was doxorubicin 45 mg/m(2) for day 1, TXL 150 mg/m(2) and CBDCA AUC 5 for day 2.

This trial aimed to define a recommended safe dose (RSD) of weekly paclitaxel and irinotecan combined with carboplatin in patients with advanced cancer. Patients with advanced cancer were eligible for this trial. Dose-limiting toxicity (DLT) was considered to be any grade greater than or equal to 3 (G> or =3) nonhematological toxicity except nausea/vomiting, G4 hematological toxicity of more than 4 days without recombinant human granulocyte colony-stimulating factor support, concurrent diarrhea G> or =2 and neutropenia G> or =3, and a treatment delay for more than 14 days because of toxicity. Patients were given carboplatin area under the curve (AUC) 5 mg*min/ml on day 1 combined with irinotecan and paclitaxel on days 1 and 8, every 3 weeks. The starting dose of both irinotecan and paclitaxel was 50 mg/m and a toxicity-guided escalation/de-escalation was planned by 10 mg/m steps. Sixteen patients were enrolled. DLTs occurred in three of the four patients treated at the starting dose level, which defined that dose as the maximum tolerated dose. Accrual continued with irinotecan and paclitaxel doses, which were de-escalated by one step. At this dose level, two of the 12 patients developed DLT, which defined that dose as the RSD. We concluded that the maximum tolerated dose of weekly irinotecan and paclitaxel when given in combination with carboplatin AUC 5 mg*min/ml was 50 mg/m and the RSD 40 mg/m. DLTs were febrile neutropenia, concurrent neutropenia (G3) and diarrhea (G3), and prolonged treatment delay because of toxicity. The most common non-DLT G3/G4 toxicity was leukopenia and neutropenia (18%), and thrombocytopenia and diarrhea (6%). A patient with metastatic endometrial carcinoma treated at the RSD had a compete response of retroperitoneal lymph node metastases, lasting for more than 3 years. Two other patients had their minimal tumor shrinkage documented. Paclitaxel (40 mg/m) and irinotecan (40 mg/m) can safely be administered on days 1 and 8 in combination with carboplatin AUC 5 mg*min/ml given on day 1. At the recommended doses this is a well-tolerated regimen with noticeable antitumor activity and warrants further investigation in phase II studies.

Granulocyte colony-stimulating factor (G-CSF)-producing nonhematopoietic malignancies have been reported in various organs, and most of them have been associated with poor clinical outcome. However, because of the rarity of reported cases, information regarding G-CSF-producing gynecological malignancies, especially uterine corpus cancer, is limited. We report a case of G-CSF-producing endometrial cancer, which exhibited a grave clinical outcome. Our case strongly indicates the aggressive nature of G-CSF-producing endometrial cancer.

Derivative (5;19)(p10;q10) [der(5;19)(p10;q10)] is a rare chromosomal abnormality in myelodysplastic syndrome (MDS), and is genetically similar to deletion 5q [del(5q)]. However, MDS with der(5;19)(p10;q10) and 5q- syndrome are generally characterized as distinct subtypes. Here, we report a case of a patient with 5q- syndrome-like features as the first manifestation of MDS with der(5; 19)(p10;q10). A 59-year-old woman was admitted to our hospital for anemia without leukopenia and thrombocytopenia. She had received chemotherapy comprising carboplatin and docetaxel for endometrial cancer eight years before. Bone marrow aspirate (BM) revealed low blast counts with trilineage dysplastic cells, and fluorescent in situ hybridization revealed the loss of colony-stimulating factor 1 receptor (CSF1R) signals at 5q33-34. Although the initial manifestation was 5q- syndrome, G-banded metaphase analysis and spectral karyotyping analysis revealed der(5;19)(p10;q10). Consequently, a diagnosis of therapy-related MDS (t-MDS) was made. She failed to respond to azacitidine and lenalidomide therapy. Consequently, transfusion-dependent anemia and thrombocytopenia developed with increasing myeloblasts. Cytarabine, aclarubicin, and granulocyte colony-stimulating factor therapy also failed, and unfortunately the patient died. Thus, MDS with der(5;19)(p10;q10) may represent a platinum agent-related t-MDS that is highly resistant to chemotherapy.

Systemic inflammatory responses including thrombocytosis, leukocytosis, or neutrophilia have gained attention as prognostic indicators in patients with various solid malignancies.current study, we aimed to investigate the clinical implications and underlying biological mechanism of the systemic inflammatory response in endometrial cancer. Clinical data from 900 patients with endometrial cancer were analyzed to investigate the association between pretreatment leukocytosis, thrombocytosis, and treatment outcome. Clinical samples, endometrial cancer cell lines, and a mouse model of endometrial cancer were used to examine the mechanisms responsible for systemic inflammatory response in endometrial cancer, focusing on the role of tumor-derived granulocyte colony-stimulating factor (G-CSF) and MDSCs. Then, we showed that pretreatment concurrent leukocytosis and thrombocytosis is associated with significantly shorter survival and decreased chemosensitivity among patients with endometrial cancer. In vitro and in vivo experiments revealed that tumor-derived G-CSF and G-CSF-mediated IL-6 production from the tumor microenvironment are involved in the development of leukocytosis and thrombocytosis in patients with endometrial cancer. Moreover, increased tumor-infiltrating MDSCs induced by tumor-derived G-CSF, MDSC-mediated T cell suppression, and MDSC-mediated cancer stem cell induction are responsible for progression and chemoresistance in this type of endometrial cancer. MDSC depletion using an anti-Gr-1 neutralizing antibody or inhibition of MDSC activity by celecoxib inhibited tumor growth and enhanced chemosensitivity in endometrial cancer displaying concurrent leukocytosis and thrombocytosis. In conclusion, Pretreatment concurrent leukocytosis and thrombocytosis are associated with significantly shorter survival and decreased chemosensitivity among patients with endometrial cancer. Combining MDSC-targeting treatments with current standard chemotherapies might have therapeutic efficacy for these patients.
