Phase II clinical trial of capecitabine in the treatment of advanced, persistent or recurrent squamous cell carcinoma of the cervix with translational research: a gynecologic oncology group study

PURPOSE: To evaluate the anti-tumor activity and adverse events of capecitabine in advanced, persistent or recurrent squamous cell carcinoma of the cervix, and to explore biomarkers with the potential to predict capecitabine response and toxicity. EXPERIMENTAL DESIGN: Eligible, consenting patients were treated with a starting dose of 2500 mg/m(2)/day or 1800 mg/m(2)/day (divided into two doses given every 12 h) for 14 days of each 21-day cycle. Prior chemotherapy was allowed only in the context of radiation "sensitization". Genotyping in the 5' and 3' ends of thymidylate synthase (TS) was performed in DNA from pretreatment blood. Relative gene expression of TS, dihydropyrimidine dehydrogenase (DPD) and thymidine phosphorylase (TP) was quantified in RNA extracted from paraffin-embedded tumor. RESULTS: All patients had prior radiotherapy and 22 received a radiation sensitizer. A partial response was observed in 4 of 26 (15%) evaluable patients. An additional 35% of patients achieved stable disease while 42% experienced increasing disease. The most common serious non-hematological toxicities were gastrointestinal and dermatologic. Exploratory analyses suggested that: a germline polymorphism in the 3' or the 5' end of TS was not associated with TS gene expression, relative tumor expression of TS, DPD and TP were not correlated, and relative tumor expression of TP may predict severe anemia. CONCLUSIONS: Based on the modest response rate, this trial was closed without a second stage of accrual; single agent capecitabine was not selected for further study in advanced persistent or recurrent squamous cell carcinoma of the cervix previously treated with radiation or chemoradiation.     

A phase II study of irofulven in women with recurrent and heavily pretreated ovarian cancer

OBJECTIVE: To determine the safety and efficacy of a novel illudin S derivative, irofulven (MGI-114), in patients with recurrent ovarian cancer who had received extensive prior chemotherapy. METHODS: The trial was an open label phase II study. Patients initially enrolled in this study were treated every 14 days with a dose of 24 mg/m2. Unexpected retinal toxicity associated with this dose and schedule lead to modification of the dosing to 0.55 mg/kg on the same schedule with a maximum individual dose of 50 mg. Dose reductions were permitted based on both hematologic and non-hematologic toxicities. RESULTS: Seventy-four women were accrued and stratified into two cohorts including 58 women with platinum-resistant disease and 16 with platinum-sensitive disease. Non-hematologic toxicities included nausea, vomiting, and fatigue. Thirty-one women had between one and six visual symptoms, most were Grade 1 and 2 in nature. The majority of visual toxicities resolved either during treatment or post-treatment with irofulven. There was one partial response in each cohort with 19 (33%) and 8 (50%) of women having stable disease in the platinum-resistant and platinum-sensitive cohorts, respectively. CONCLUSIONS: Irofulven at 24 mg/m2 on every 14-day schedule is associated with significant retinal toxicity in this patient population. Dosing at 0.55 mg/kg has persistent retinal toxicity, yet demonstrated only limited anti-tumor activity in a population of women who had received extensive prior chemotherapy.     

Phase II evaluation of 24-h continuous infusion topotecan in recurrent, potentially platinum-sensitive ovarian cancer: A Gynecologic Oncology Group study

OBJECTIVES: The aim of this study was to develop an alternative effective and more convenient administration schedule for intravenous topotecan when used as palliative treatment in ovarian cancer. METHODS: The Gynecologic Oncology Group conducted a Phase II trial of 24-h infusional topotecan (8.5 mg/m(2)) with treatment repeated every 3 weeks in 29 patients with platinum-sensitive recurrent ovarian cancer (prior response to platinum-based chemotherapy with a minimum treatment-free interval >/=6 months). RESULTS: The major toxicities of therapy were grade 4 neutropenia and thrombocytopenia which developed in 86 and 14% of patients, respectively. Other severe side effects were uncommon. Only 2 partial responses (7%) were observed in the 28 patients evaluable for response. CONCLUSIONS: Despite the relatively favorable ovarian cancer patient population treated in this trial (platinum-sensitive recurrent disease), the response rate was disappointingly low. Considering the three- to fivefold higher objective response rates observed in other trials employing topotecan in individuals with platinum-sensitive ovarian cancer utilizing a 5-day treatment program (delivered every 3 weeks), the results of the current study provide strong support for the conclusion that clinically relevant antineoplastic activity of this agent is highly schedule dependent.     

A phase II evaluation of tirapazamine plus cisplatin in the treatment of recurrent platinum-sensitive ovarian or primary peritoneal cancer: a Gynecologic Oncology Group study

OBJECTIVES: To estimate the anti-tumor activity, nature and degree of toxicity of tirapazamine in combination with cisplatin in patients with recurrent platinum-sensitive ovarian or primary peritoneal cancers. METHODS: Eligible consenting patients had to have recurrent epithelial ovarian or primary peritoneal carcinoma with measurable disease. Patients were not allowed to have received any additional cytotoxic chemotherapy for management of recurrent or persistent disease, including re-treatment with initial chemotherapy regimens. Patients must have been platinum-sensitive, meaning a treatment-free interval of >6 months after response to a platinum-based regimen. The RECIST criteria were used for parameters of response. Tirapazamine was administered at a dose of 390 mg/m2 IV over 2 h followed 1 h later by cisplatin 60 mg/m2 IV every 3 weeks until disease progression or adverse effects prohibited further therapy. RESULTS.: Between June 2001 and February 2004, 65 patients were entered onto this study by 27 institutions; one patient was excluded due to ineligible tumor type. Twenty-six patients (41%) received six or more cycles of therapy; however, 16 (25%) received one course of therapy (mainly due to side effects or patient request). There were six (9%) complete responders and 28 (44%) partial responders for a total response rate of 53%. Only two patients (3%) developed increasing disease on this protocol, and response could not be assessed in 18 patients (28%). The median progression-free and overall survival for all patients is 10.9 and 26.4 months, respectively. The regimen did not cause major hematologic toxicity, however, it did cause frequent constitutional (23%) and gastrointestinal (mostly nausea/vomiting) (44%) grade 3 or 4 toxicity. CONCLUSIONS: The combination of tirapazamine and cisplatin has definite activity in the treatment of recurrent platinum-sensitive ovarian or primary peritoneal cancer. However, toxicity, primarily non-hematologic, was substantial. Reducing the toxicity of a tirapazamine-platinum combination should be pursued in future trials.

Survey of medicinal cannabis use among childbearing women: patterns of its use in pregnancy and retroactive self-assessment of its efficacy against 'morning sickness'

A majority of women experience some nausea and/or vomiting during pregnancy. This condition can range from mild nausea to extreme nausea and vomiting, with 1-2% of women suffering from the life-threatening condition hyperemesis gravidarum. Cannabis (Cannabis sativa) may be used therapeutically to mitigate pregnancy-induced nausea and vomiting. This paper presents the results of a survey of 84 female users of medicinal cannabis, recruited through two compassion societies in British Columbia, Canada. Of the seventy-nine respondents who had experienced pregnancy, 51 (65%) reported using cannabis during their pregnancies. While 59 (77%) of the respondents who had been pregnant had experienced nausea and/or vomiting of pregnancy, 40 (68%) had used cannabis to treat the condition, and of these respondents, 37 (over 92%) rated cannabis as 'extremely effective' or 'effective.' Our findings support the need for further investigations into cannabis therapy for severe nausea and vomiting during pregnancy.     

Efficacy and toxicity of weekly topotecan in recurrent epithelial ovarian and primary peritoneal cancer

OBJECTIVES: We assessed the efficacy and toxicity of once-weekly topotecan (Hycamtin; GlaxoSmithKline) for relapsed or persistent epithelial ovarian cancer (EOC) and primary peritoneal carcinoma (PPC). METHODS: Patients with recurrent or persistent EOC and PPC previously treated with > or = 1 course of platinum-based chemotherapy were treated with weekly topotecan 4.0 mg/m2 on days 1, 8, and 15 of a 28-day cycle in this prospective open-label, single-arm, phase II study. RESULTS: The median age of the 63 study patients was 63 years (range, 36-88); patients had been previously exposed to a median of 1 course (range, 1-4) of chemotherapy. A median of 5 courses (range, 1-16) were administered. Median follow-up time was 13. 2 month s (range, 1.5-39.0). The overall response rate (RR) was 23.8%, of which 17.5% (11 patients) represented a complete response and 6.3% (4 patients) a partial response. Patients with platinum-sensitive disease had a RR of 20%, whereas patients with platinum-resistant disease had a RR of 28.6%. Median time to progression was 6.2 months (95% confidence interval: 4.43, 7.97), and median survival from initiation of topotecan therapy was 22.3 months (95% confidence interval: 14.56, 30.04). Hematologic toxicities included grade 3 anemia in 3 (4.8%) patients, grade 3 thrombocytopenia in 3 (4.8%) patients, and grades 3-4 neutropenia in 5 (7.9%) patients. Dose reductions, granulocyte colony-stimulating factor, and erythropoietin support were required by 10 (15.9%), 6 (9.5%), and 16 (25.4%) patients, respectively. The most frequent nonhematologic toxicities were grades 2-3 fatigue in 10 (15.9%) patients and grades 2-3 nausea/vomiting in 3 (4.7%) patients. CONCLUSION: Weekly administration of topotecan 4.0 mg/m2 is active and well tolerated by patients with recurrent or persistent EOC and PPC.     

Phase II study of gemcitabine and oxaliplatin in patients with recurrent ovarian cancer: an Australian and New Zealand Gynaecological Oncology Group study

Gemcitabine and oxaliplatin have shown single-agent activity in relapsed ovarian cancer. This combination was used to determine response rates, time-to-event efficacy measures, and toxicity in patients with recurrent ovarian cancer. Patients with prior platinum-based chemotherapy who had measurable lesions and/or elevated CA-125 levels were identified as group A (platinum-refractory/platinum-resistant patients) and group B (platinum-sensitive patients). All patients received gemcitabine 1000 mg/m(2) on days 1 and 8 and oxaliplatin 130 mg/m(2) on day 8 every 21 days for up to eight cycles. Seventy-five patients (21 in group A and 54 in group B), with a median age of 58 years (range, 37-78), were enrolled. A median of six cycles (range, 1-8) was administered. By intent-to-treat analysis, 15 patients with measurable disease achieved partial response for an overall best response rate of 20.0% (9.5% in group A and 24.1% in group B). CA-125 response was observed in 48.4% patients (30.0% in group A and 57.1% in group B). Median time to progressive disease was 7.1 months (95% CI, 5.6-9.0 months) with 5.0 months in group A and 8.3 months in group B. Median overall survival was 17.8 months (95% CI, 12.9-21.3 months) with 9.2 months for group A and 20.0 months for group B. Major grade 3/4 toxicities were neutropenia (61.3%), leukopenia (24.0%), nausea (16.0%), and vomiting (22.7%). We conclude that the combination of oxaliplatin and gemcitabine is active in patients with recurrent ovarian cancer, but the regimen is unsatisfactory for further study due to modest response and relatively high toxicity.     

The "Leuven" dose-dense paclitaxel/carboplatin regimen in patients with recurrent ovarian cancer

OBJECTIVE: The purpose of this study was to evaluate the "Leuven" dose-dense regimen in recurrent ovarian cancer. METHODS: Six courses of paclitaxel (90 mg/m(2)) and carboplatinum (AUC 4) on d1 and d8 every 3 weeks were administered. Response rates were determined using RECIST and Gynaecological Cancer Intergroup (GCIG) CA 125 criteria. Platinum resistance was defined as progression during or within 6 months after platinum-based chemotherapy. RESULTS: Thirty-three patients were included with a median number of prior treatment regimens of 2. Nine patients were platinum-resistant and 24 were platinum-sensitive. Three of 8 patients in the platinum-resistant group and 16 of 21 patients in the platinum-sensitive group achieved an evaluable response according to RECIST. According to the GCIG CA 125 criteria 3 of 7 patients in the platinum-resistant and 17 of 19 patients in the platinum-sensitive patients responded. In the entire patient population evaluable for response (n=29), the median progression-free survival (PFS) was 9 months; the median overall survival (OS) was 18 months. Median PFS was 6.75 months for the platinum-resistant and 10.5 months for the platinum-sensitive group. The median OS was 8 months in the platinum-resistant and not yet reached in the platinum-sensitive group. Toxicity was mostly bone marrow-related with neutropenia grade 3/4 in 34% and neutropenic fever in 2% of courses. Dose reduction was necessary in 25% of patients. Nausea and vomiting and fatigue were the most frequent non-hematological side effects. CONCLUSION: Dose-dense paclitaxel and carboplatin offers a well-tolerated regimen with high response rates even in heavily pre-treated and platinum-resistant ovarian cancer.     

Second-line chemotherapy with gemcitabine and carboplatin in paclitaxel-pretreated, platinum-sensitive ovarian cancer patients. A Hellenic Cooperative Oncology Group Study

OBJECTIVE: Patients with epithelial ovarian cancer (EOC) who relapse more than 6 months following completion of platinum-based primary chemotherapy are considered platinum-sensitive, and can be effectively retreated with cisplatin or carboplatin. The nucleoside analogue gemcitabine has proven activity in both platinum-sensitive and platinum-resistant disease. We conducted a phase II study using the combination of carboplatin and gemcitabine for the treatment of patients with relapsed platinum-sensitive and paclitaxel-pretreated EOC. METHODS: Forty-three patients were treated with gemcitabine 1000 mg/m(2), intravenously, over 30 min on days 1 and 8, and carboplatin at AUC 5 on day 1. Courses were administered every 3 weeks on an outpatient basis. RESULTS: Among 37 patients with measurable or evaluable disease, 15 (40.5%) achieved an objective response including 10 complete and 5 partial responses. The median overall survival was 24.5 months, and the median time to progression for all patients was 9 months. The treatment was well tolerated without toxic deaths; the most common toxicities were Grade 3 or 4 neutropenia, anemia, and thrombocytopenia that occurred in 69%, 26%, and 24% of patients, respectively. CONCLUSIONS: The combination of carboplatin and gemcitabine is a well-tolerated outpatient regimen with activity in patients with relapsed platinum-sensitive and paclitaxel-pretreated EOC. However, a randomized prospective study is justified to define whether the addition of gemcitabine to single-agent carboplatin results in improved efficacy in this subset of patients.     

A phase II study of gemcitabine plus carboplatin in platinum-sensitive, recurrent ovarian carcinoma

OBJECTIVES: Gemcitabine and carboplatin each have demonstrated effectiveness without increased neurotoxicity in pretreated patients with ovarian cancer. We evaluated the efficacy and safety of gemcitabine plus carboplatin in patients with recurrent ovarian cancer in a multicenter phase II study. METHODS: Women with histologically proven measurable or evaluable epithelial ovarian cancer (any FIGO) who relapsed > or =6 months after discontinuation of first-line, platinum-containing therapy received gemcitabine 1000 mg/m(2) on days 1 and 8 and carboplatin AUC 4 on day 1 (after gemcitabine) every 21 days for up to six cycles. RESULTS: Of the 40 enrolled/evaluable patients, 6 (15%) had complete response and 19 (47.5%) had partial response (PR), including one patient with PR in nonmeasurable disease (PRNM), for an overall response rate of 62.5% (95% CI, 45.8-77.3%). The median duration of response was 7.8 months (95% CI, 6.7-10.0), the median time to progressive disease was 9.6 months (95% CI, 8.5-11.0), and the median time to treatment failure was 9.3 months (95% CI, 8.2-10.4). The main grade 3/4 toxicities were neutropenia (78% of patients), leukopenia (30%), thrombocytopenia (18%), and anemia (15%); no grade 4 nonhematologic toxicities occurred, and grade 3 nonhematologic toxicities were mild. CONCLUSIONS: The combination of gemcitabine and carboplatin is active and feasible in platinum-sensitive patients with recurrent ovarian cancer. This regimen is undergoing further evaluation in a large phase III trial.     

A phase II trial of weekly topotecan for patients with secondary platinum-resistant recurrent epithelial ovarian carcinoma following the failure of second-line therapy

OBJECTIVE: To determine the response rate, progression-free survival and toxicity associated with weekly topotecan administered to patients with platinum-sensitive recurrent epithelial ovarian (EOC) in the third-line setting. METHODS: Patients with measurable platinum-sensitive EOC following failure of second-line chemotherapy were eligible for this phase II study. All patients were initially treated with cytoreductive surgery and platinum/paclitaxel-based chemotherapy. Continuous, weekly topotecan was administered at a starting dose of 4 mg/m(2). Toxicity and efficacy were assessed at various time points after initiation of therapy. RESULTS: Twenty nine patients were enrolled in this prospective study. Toxicity was acceptable with grade 1/2 nausea being the most commonly experienced side effect (52%). Nine patients (31%) had grade 3/4 leukopenia; however, only 3 patients had febrile neutropenia. Thirteen patients had a treatment delay and six required dose reductions. Twenty two patients were evaluable for efficacy. The overall response rate for weekly topotecan was 13.6% [95% CI; -0.7-27.9%] with 1 complete response, and 2 partial responses. Twelve patients (54.5%), including 2 with minor responses, had stable disease for a median duration of 18 weeks. CONCLUSIONS: Weekly topotecan at the current schedule in the third-line setting in patients with platinum-sensitive recurrent EOC has modest clinical activity. Toxicity associated with this regimen is acceptable but growth factor support, dose reductions, or schedule alterations may need to be considered in many of these patients.     

Meclizine for prevention of nausea associated with use of emergency contraceptive pills: a randomized trial

OBJECTIVE: We conducted a randomized trial to determine whether pretreatment with meclizine reduces the incidence of nausea and vomiting associated with the Yuzpe regimen of emergency contraception. METHODS: We randomly assigned 343 women aged 18-45 years who were not at risk for pregnancy to pretreatment with 50 mg of meclizine, placebo, or no drug 1 hour before the first of two doses of emergency contraceptive pills. We asked participants to complete three questionnaires over the following 48 hours. RESULTS: The incidence of nausea was 47% in the group pretreated with meclizine and 64% in the other two groups (relative risk adjusted for center 0.7, 95% confidence intervals 0.6, 0.9 for comparisons of meclizine with both placebo and no drug). The severity of nausea and the incidence of vomiting were also significantly lower in the meclizine pretreatment group than in the other two groups. Drowsiness was reported by about twice as many women in the meclizine pretreatment group (31%) than in the other two groups (13% in the placebo group, 16% in the no-pretreatment group; P < .01 for both comparisons). CONCLUSION: Meclizine is effective for preventing nausea and vomiting associated with the Yuzpe regimen of emergency contraceptive pills. Women using this drug should be cautioned to anticipate drowsiness.     

A phase II trial of pemetrexed in combination with carboplatin in patients with recurrent ovarian or primary peritoneal cancer

Objective

Carboplatin-based combinations are commonly used in platinum-sensitive ovarian cancer (PSOC). Pemetrexed in combination with carboplatin has been shown to be feasible in a phase I study in PSOC. The primary objective of this subsequent phase II study was to determine the overall response rate (ORR; defined by Response Evaluation Criteria in Solid Tumors) of this combination in patients with recurrent PSOC. Secondary objectives included progression-free survival (PFS), overall survival (OS), and toxicity.

Methods

Patients with PSOC (defined by recurrence ≥ 6 months after completion of up to two lines of prior platinum-based therapy), measurable disease, Eastern Cooperative Oncology Group performance status of 0 to 2, and adequate organ function were eligible. Pemetrexed 500 mg/m² was administered as a 10-minute infusion followed by carboplatin AUC 6 as a 30-minute infusion on day 1 of a 21-day cycle.

Results

Sixty-six patients were treated. Of the 61 patients evaluable for response, there were 20 responders (one complete response and 19 partial responses), for an ORR of 32.8% (95% CI: 21.3%, 46.0%). For the intent-to-treat population (all 66 patients), the median PFS was 9.4 months (95% CI: 8.3, 11.1), with 22.7% censoring. Median OS was not reached due to the high censoring rate. There was one drug-related death (multi-organ failure). The most common drug-related grade 3/4 toxicities were neutropenia (39.4%), thrombocytopenia (24.2%), carboplatin hypersensitivity (9.1%), nausea (6.1%), and vomiting (6.1%).

Conclusions

Carboplatin AUC 6 and pemetrexed 500 mg/m² has a low incidence of serious toxicities. Defining the platinum-based combination with the best therapeutic index would require a prospective phase III study.     

A Phase 2 study of cisplatin analog CI-973 in the treatment of patients with refractory, advanced ovarian cancer

The platinum analog CI-973 was selected for clinical study because it is associated with fewer and milder toxicities than either cisplatin or carboplatin in experimental animals, and because it has activity against cisplatin-resistant cell lines in vitro . In this Phase 2 study, 31 women with platinum-resistant or recurrent ovarian carcinoma were treated with CI-973. Three patients achieved a complete response, defined as the disappearance of all measurable disease. The median Kaplan-Meier survival time was estimated to be approximately 7 months from the start of treatment. The most frequently occurring drug-related toxicities were neutropenia, nausea, vomiting, asthenia, anemia, abdominal pain, and diarrhea. Most toxicities were mild or moderate and none resulted in withdrawal from treatment. Despite this favorable toxicity profile, the low response rate of 10% does not support further clinical development of CI-973 as treatment for ovarian cancer.     

A phase II study of gemcitabine,carboplatin and bevacizumab for the treatment of platinum-sensitive recurrent ovarian cancer

Purpose

The doublet gemcitabine and carboplatin is effective for the treatment of recurrent ovarian cancer, while multi-agent chemotherapy with bevacizumab may add additional benefit. This phase II study tested the efficacy and safety of a biweekly gemcitabine, carboplatin, and bevacizumab combination in patients with platinum-sensitive recurrent ovarian, peritoneal, or tubal cancer (ROC).

Patients and methods

Eligible patients received concurrent gemcitabine 1000 mg/m², carboplatin area under the curve 3, and bevacizumab 10 mg/kg administered intravenously on days 1 and 15 every 28 days for six cycles or up to 24 cycles if clinical benefit occurred. The primary end points were progression-free survival (PFS) by RECIST, and safety; the secondary end points were objective response rates and overall survival.

Results

Overall, 45 patients were enrolled. The median PFS was 13.3 months (95% CI, 11.3 to 15.3). The objective response rate was 69%. Grade 4 hematologic toxicities included neutropenia (27%) and thrombocytopenia (2%). Grades 3 and 4 non-hematologic toxicities included fatigue (18%), pain (9%), and nausea/vomiting (4%). There were 2 episodes of cerebrovascular accidents, 2 noted DVTs, and no episodes of bowel perforation. Median OS was 36.1 months (95% CI, 26.7 to 45.5).

Conclusion

Biweekly gemcitabine, carboplatin, and bevacizumab were an effective regimen in recurrent ovarian cancer, with comparable toxicity to recently reported day 1 gemcitabine, carboplatin, bevacizumab, and day 8 gemcitabine. Response rate and PFS are improved from reported outcomes of the gemcitabine carboplatin doublet. The degree to which biweekly dosing may present a more rationale schedule for this triplet should be evaluated further.     

Psychosocial morbidity among women with nausea and vomiting of pregnancy: prevalence and association with anti-emetic therapy

Unlike severe nausea and vomiting of pregnancy (NVP), it is not known whether milder forms of NVP have been associated with psychosocial morbidity. We undertook the study to explore the prevalence of psychosocial morbidity by severity of NVP, and determine whether, after correction for severity of nausea/vomiting, there is a relationship between psychosocial morbidity and women's decisions to take anti-emetics as a reflection of their distress due to NVP. From 1996-97, an NVP Healthline was advertised. Callers underwent semi-structured interviews about both their NVP and associated psychosocial morbidity in a previous pregnancy. Most of the 3201 callers resided in Canada, worked outside the home, reported on planned pregnancy (a median of) 4 years before, and described severe (> 5 episodes/day of) nausea and vomiting. More severe nausea/vomiting was associated with more frequent feelings of depression, consideration of termination of pregnancy, adverse effects on women's relationships with their partners or their partners' everyday lives, and the perceived likelihood that NVP would harm their baby (p < 0.0001). However, all psychosocial factors were reported by a clinically important proportion of women with mild nausea/vomiting (0-1 episodes/day). The severity of vomiting was most closely related to women's decisions to take anti-emetics, but other psychosocial factors were also independently associated with anti-emetic therapy. We conclude that psychosocial morbidity is evident across the spectrum of severity of nausea and vomiting among women with NVP. The severity of nausea or vomiting does not appear adequately to reflect the distress caused by NVP, as reflected by women's decisions to take anti-emetic therapy.     

Phase II evaluation of oxaliplatin in previously treated squamous cell carcinoma of the cervix: a gynecologic oncology group study

OBJECTIVE: A phase II study was conducted to determine the efficacy of oxaliplatin therapy in patients with previously treated squamous cell carcinoma of the cervix. METHODS: Eligible patients were to have measurable disease and not more than one prior chemotherapy regimen that could include carboplatin or cisplatin but not oxaliplatin. Oxaliplatin 130 mg/m(2) was administered intravenously over 2 h. This treatment was repeated every 21 days until progression of disease or adverse effects prohibited further therapy. RESULTS: Twenty-eight patients were entered onto this study, of whom 24 were evaluable for toxicity and 22 were evaluable for response; 23/24 evaluable patients had had prior platinum. There were two (8.3%) responses. One patient achieved a complete response which lasted 2.2 months, and a second patient attained a partial response which lasted 3.2 months. Nine (37.5%) patients had stable disease with a median duration of 7.6+ (3.1-21.2) months. The most frequently reported drug-related toxicities consisted of anemia, nausea and vomiting, and neurotoxicity. Three (12.5%) patients had a grade 3 allergic response that was infusion-related and was largely resolved by increasing infusion time. CONCLUSIONS: Oxaliplatin has limited activity in patients with persistent or recurrent squamous cell carcinoma of the cervix at the dose and schedule tested.     

Phase II trial of docetaxel and carboplatin in recurrent platinum-sensitive ovarian, peritoneal and tubal cancer

OBJECTIVE: Docetaxel and carboplatin are active in relapsed ovarian, peritoneal and tubal cancer. Recently, two prospective-randomized trials showed an advantage of carboplatin combination regimen with paclitaxel or gemcitabine over carboplatinum alone in platinum-sensitive cases. The question on the most effective combination with the best tolerable side effects still needs to be answered. METHODS: Eligible patients had recurrent ovarian, peritoneal or tubal cancer (platinum-free interval >6 months), performance status 0-2 and normal bone marrow, renal and hepatic function. 25 patients (age 18-75 years) were enrolled into this phase II trial. Patients with debulking operation of recurrence were excluded from this study. Docetaxel 75 mg/m(2) via 30-min infusion was given on day 1 followed by carboplatin (area under curve [AUC] 5) on day 1. The administration was repeated every 3 weeks over 6 courses. Primary endpoint of this trial was the response rate; secondary endpoints were progression-free survival, overall survival and toxicity. RESULTS: In the intent-to-treat population, there were 16 (64.0%) complete and 2 (8.0%) partial responses resulting in an overall response rate of 72.0%. Three patients (12.0%) showed a stable disease and other 2 patients (8.0%) a progression of cancer. Two patients (8.0%) were not evaluable for response. Neutropenia was the most frequent G3/G4 hematologic toxicity in 15/25 patients (60.0%); but no neutropenic fever occurred in this trial. Diarrhea G3 was the most frequent G3/G4 non-hematologic toxicity in only 3/25 patients (12.0%). Dose-limiting toxicities were hypersensitivity reaction in one and depressive mood alteration requiring therapy in another case. CONCLUSION: Carboplatin in combination with docetaxel is highly active and well tolerated in patients with recurrent platinum-sensitive ovarian, peritoneal and tubal cancer. Prospective-randomized trials comparing this with other carboplatin therapeutic doublets in patients with recurrent ovarian cancer are a possible option for the future to answer the question on the best combination regimen.     

A comparison of different severities of nausea and vomiting during pregnancy relative to stress, social support, and maternal adaptation

A cross-sectional and comparative research design with convenience sampling was used to recruit pregnant women from prenatal clinics in southern Taiwan between 2002 and 2003 to examine the differences in perceived stress, social support, and maternal psychosocial adaptation among women with different severities (mild or less than mild, moderate, and severe) of nausea and vomiting during pregnancy. A total of 150 pregnant women participated in this study. One-way analysis of variance indicated that perceived stress was significantly different among the 3 groups. The least significant difference post-hoc test revealed that pregnant women with mild nausea and vomiting had significantly lower stress than did pregnant women with severe nausea and vomiting. The severity of nausea and vomiting was significantly associated with the Prenatal Self Evaluation Questionnaire subscales for "acceptance of pregnancy" and "fear of helplessness and loss of control in labor." Social support and maternal psychosocial adaptation were not significantly different among these three groups. The degree of perceived stress and maternal psychosocial adaptation may be related to the severity of nausea and vomiting during pregnancy.
