Gemcitabine, 5-Fluorouracil, and Leucovorin in Advanced Biliary Tract and Gallbladder Carcinoma: a North Central Cancer Treatment Group Phase II Trial

BACKGROUND: Gemcitabine has broad activity in a variety of solid tumors including biliary tract carcinomas. The authors evaluated 6-month survival, response, and toxicity associated with a combination of gemcitabine, 5-fluorouracil (5-FU), and leucovorin (LV) in patients with unresectable or metastatic biliary tract or gallbladder adenocarcinoma (ACA). METHODS: A 4-week course included 1000 mg/m2 gemcitabine by intravenous infusion over 30 minutes on Days 1, 8, and 15, 25 mg/m2 LV by intravenous push, and 600 mg/m2 5-FU by intravenous push after LV. RESULTS: Forty-two patients were enrolled in 6 months, 35 of whom had metastatic disease. Patients with biliary tract ACA included 24 with hepatic disease (19 patients had intrahepatic disease and 5 patients had extrahepatic disease) and 4 with disease in the ampulla of Vater. All patients were evaluable and received a median of 4 courses of treatment (range, 1-21 courses). Commonly occurring severe toxicity (NCI CTC Grade 3 or worse) included: dyspnea (four patients), nausea (four patients), fatigue (seven patients), thrombocytopenia (six patients), emesis (four patients), and diarrhea (four patients). Five partial responses (9.5%) occurred, 3 of which were sustained for \u3e or = 8 weeks. No treatment-related deaths occurred. Thirty-two patients had disease progression and 38 died after a median follow-up of 20 months (range, 1.4-24 months). The median time to disease progression was 4.6 months (95% confidence interval [95% CI], 2.4-6.6%). The median survival period was 9.7 months (95% CI, 7-12%). CONCLUSIONS: This combination regimen was manageable in patients with advanced biliary tract and gallbladder ACA. Of 42 patients, 24 (57%) survived \u3e or = 6 months, satisfying the primary end point of the trial. The length of survival suggested that gemcitabine, 5-FU, and LV had benefit equivalent to gemcitabine alone

Long-Term Survival of Patients with Advanced/Recurrent Carcinoma of Cervix and Vagina After Neoadjuvant Treatment with Methotrexate, Vinblastine, Doxorubicin, and Cisplatin with or without the Addition of Molgramostim, and Review of the Literature.

A randomized phase III study was conducted to assess the addition of molgramostim (GM-CSF) to the combination of methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) in terms of response rate, progression-free survival, and survival in women with advanced, recurrent, or metastatic carcinoma of the cervix or vagina. Patients received four 4-week cycles of methotrexate 30 mg/m2 IV days 1, 15, 22; vinblastine 3 mg/m2 IV days 2, 15, 22; doxorubicin 30 mg/m2 IV day 2; and cisplatin 70 mg/m2 IV day 2 with or without GM-CSF 5 microg/kg every 12 hours subcutaneously days 3 to 12. They were then reevaluated for operability. Those who were not surgical candidates were offered additional chemotherapy until progression or toxicity. Those who were surgical candidates were offered surgical resection of remaining tumor followed by involved-field external beam irradiation to sites of no prior irradiation and intraoperative irradiation to sites of prior external beam irradiation. This trial closed after 36 eligible patients were entered because of poor accrual. Although more than 40% of patients on each arm received fewer than four cycles of MVAC, the clinical response rate was 78% (95% CI: 52-94%) and 50% (95% CI: 26-74%) for MVAC and MVAC + GM-CSF, respectively; the median time to progression was 10.2 and 11.8 months, respectively; and median survival was 13.8 and 16.0 months, respectively. Toxicity was substantial, with more than 40% experiencing grade III to IV leukopenia, and nearly 40% experiencing grade III to IV stomatitis. MVAC with or without GM-CSF support achieves high response rates in patients with advanced, recurrent, or metastatic cervical carcinoma despite dose reductions and deletions. Its progression-free survival and overall survival rates appear promising. These results need to be confirmed within a large randomized phase III clinical trial

The influence of clinical and genetic factors on patient outcome in small cell carcinoma of the ovary, hypercalcemic type

ObjectiveSmall cell carcinoma of the ovary, hypercalcemic type (SCCOHT) is an aggressive tumor, with long term survival at ~30% in early stage disease. SCCOHT is caused by germline and somatic SMARCA4 mutations, but the effect of the mutation type on patients remains unknown. Furthermore, the rarity of SCCOHT has resulted in varied treatment, with no standardized protocols. We analyzed 293 cases to determine the effect of treatment modalities and SMARCA4 mutations on patient diagnosis and outcome.MethodsIn 293 SCCOHT patients we collected information on age and stage at diagnosis, treatment modality (surgery, chemotherapy, radiotherapy, and/or high-dose chemotherapy with autologous stem cell rescue (HDC-aSCR)), SMARCA4 mutation origin (germline/somatic), and overall survival. Cox analysis and log-rank tests were performed on 257 cases with available survival data.ResultsThe strongest prognostic factors were stage at diagnosis (p=2.72e-15) and treatment modality (p=3.87e-13). For FIGO stages II-IV, 5-year survival was 71% for patients who received HDC-aSCR, compared to 25% in patients who received conventional chemotherapy alone following surgery (p=0.002). Patients aged ≥40 had a worse outcome than younger patients (p=0.04). Twenty-six of 60 tested patients carried a germline SMARCA4 mutation, including all patients diagnosed <15years; carriers presented at a younger age than non-carriers (p=0.02).ConclusionsStage at diagnosis is the most significant prognostic factor in SCCOHT and consolidation with HDC-aSCR may provide the best opportunity for long-term survival. The large fraction of SMARCA4 germline mutations carriers warrants genetic counseling for all patients
