An outpatient intraperitoneal chemotherapy regimen for advanced ovarian cancer

Utilization of an Alternative Docetaxel-based Intraperitoneal Chemotherapy Regimen in Patients With Ovarian, Fallopian Tube or Primary Peritoneal Carcinoma: A Continued Need for Ovarian Cancer Patients

OBJECTIVE

The objective of this study was to report the tolerability and toxicity of a regimen consisting of intravenous (IV) docetaxel and intraperitoneal (IP) cisplatin and paclitaxel with granulocyte colony-stimulating factor support.

MATERIALS AND METHODS

We conducted a retrospective cohort study of patients with surgical stage II-IV epithelial ovarian, fallopian tube or primary peritoneal carcinoma treated with an outpatient IP chemotherapy regimen consisting of docetaxel 75 mg/m IV and cisplatin 75 mg/m IP day 1 followed by paclitaxel 60 mg/m IP day 8 every 21 days. Grade 3 and 4 toxicity, dose delays and reductions, port complications, and tolerability are reported. Outcomes, including response rate, progression-free survival (PFS), overall survival (OS) are also reported.

RESULTS

A total of 60 patients received this IP regimen. Most common toxicities included neutropenia (47%), gastrointestinal (28%), and anemia (25%). Most patients (85%) experienced no IP port complications. Dose delay or reduction was required in 30% of patients. Two-thirds completed all prescribed cycles, with 80% of total planned cycles completed. Complete response was achieved for 88%, and 43% are currently without evidence of disease. Median PFS for all patients was 25.5 months (95% confidence interval [CI], 20.4-30.5 mo) while OS for all patients was 56.8 months (95% CI, 47.7-65.9 mo). For the 44 patients with stage III disease, median PFS was 22.1 months (95% CI, 16.3-28.0 mo), while median OS was 56.8 months (95% CI, 47.3-66.3 mo).

CONCLUSIONS

This docetaxel-based IP chemotherapy regimen demonstrates an improved tolerability profile compared with GOG172. Additional evaluations on alternative IP regimens remain warranted. Short follow-up time limits survival assessment, but results are encouraging.

Utilization and Toxicity of Alternative Delivery Methods of Adjuvant Chemotherapy for Ovarian Cancer

OBJECTIVE

Compared with conventional intravenous platinum and taxane-based chemotherapy for ovarian cancer, both intraperitoneal chemotherapy and more frequent dose-dense intravenous chemotherapy have been associated with improved survival in some studies. We examined the utilization and toxicity of these three methods of chemotherapy delivery in women with ovarian cancer.

METHODS

We performed a population-based study and analyzed data on women with ovarian cancer who underwent primary surgery followed by platinum and taxane-based chemotherapy from 2009 to 2013 who were recorded in the MarketScan database. Adjuvant chemotherapy was classified as: intraperitoneal chemotherapy, dose-dense chemotherapy (weekly administration of chemotherapy), or standard chemotherapy (every 3 weeks). Hospitalizations and emergency department visits for chemotherapy-associated complications and costs were recorded and compared using χ tests.

RESULTS

A total of 5,892 patients, including 4,135 (70.2%) who received standard chemotherapy, 859 (14.6%) who received intraperitoneal chemotherapy, and 898 (15.2%) treated with dose-dense chemotherapy, were identified. From 2009 to 2013, use of intraperitoneal chemotherapy remained constant (16.3-16.3%), whereas use of dose-dense therapy increased (8.7-18.1%) (P<.001). Hospitalizations for chemotherapy-associated complications occurred in 21.3% of women receiving standard chemotherapy, 34.7% of patients treated with intraperitoneal therapy, and in 25.2% of those receiving dose-dense treatment (P<.001); emergency department visits occurred in 18.3%, 26.3%, and 20.3%, respectively (P<.001). The largest differences in hospitalizations and emergency department visits were seen for gastrointestinal toxicities and electrolyte disorders. The per-patient costs of hospitalization were higher for intraperitoneal chemotherapy than other treatment modalities.

CONCLUSION

Intraperitoneal chemotherapy was used in less than 15% of women with ovarian cancer, whereas use of dose-dense chemotherapy is increasing. Although we did not examine survival, intraperitoneal chemotherapy is significantly more toxic than the other methods of treatment.

Update on the management and the role of intraperitoneal chemotherapy for ovarian cancer

PURPOSE OF REVIEW

Ovarian cancer is the commonest gynaecological cancer and the fifth leading cause of cancer death in women worldwide. The majority of patients with ovarian cancer present at an advanced stage, and up to 70% of those treated with a curative approach eventually recur and succumb to their disease. This article examines the management of ovarian cancer over the years and the role of intraperitoneal chemotherapy in the treatment algorithm.

RECENT FINDINGS

The surgical paradigm for ovarian cancer has changed and the goal is optimal cytoreduction with no residual disease. Intraperitoneal chemotherapy has been found to be superior to intravenous treatment alone, and the combination of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has produced encouraging results with improved disease-free and overall survivals at acceptable morbidity and mortality rates.

SUMMARY

The most important prognostic factor for ovarian cancer survival is the ability to achieve optimal cytoreduction with no residual disease. CRS and HIPEC should be considered as an option for the management of advanced ovarian cancer and further trials are required to determine its role in both the primary and recurrent settings.

Peritoneal carcinomatosis from advanced ovarian cancer: To treat or not to treat ethical issues suggested by a case study

This article provides a brief description of an epithelial ovarian cancer (EOC) case (stage IV) treated with the association of complete CytoReductive Surgery and hypertermic intraPEritoneal chemotherapy (HIPEC). The use of HIPEC in EOC makes theoretic sense in view of the high rates of recurrence following standard treatment, but there are no randomized clinical trial to date and HIPEC for these patients still represents a radical treatment where the choice of no treatment may be acceptable since definitive cure is unlikely. We reviewed the entire decision making process considering the risk/benefit of the procedure in term of mortality/morbidity, the quality of life and the psychological profile of the patient 1 year after surgery. The platform World Health Organization-International Classification of Functioning, Disability and Health that permits evaluation of the person in relation to the psycho-social context is presented. A person-centred approach and assessment of health-related quality-of-life and disability in EOC survivors are of central importance for decision making.

Toxicities, complications, and clinical encounters during intraperitoneal chemotherapy in 17 women with ovarian cancer

PURPOSE OF THE RESEARCH

Intraperitoneal (IP) chemotherapy is a viable and superior treatment to standard intravenous (IV) chemotherapy in women with small volume residual ovarian cancer following optimal debulking. Despite this clinical advantage, widespread adoption of the treatment regimen has been hampered by concerns related to toxicities and complications. The purpose of this descriptive study was to describe nursing implications related to toxicities, complications and clinical encounters in 17 women with ovarian cancer who received IP chemotherapy.

METHODS AND SAMPLE

Women with ovarian cancer who received IP chemotherapy at one NCI-designated comprehensive cancer center were accrued. Data related to IP chemotherapy summary, clinical encounters and admissions were obtained through comprehensive chart audits.

KEY RESULTS

Common treatment-related toxicities included nausea and vomiting, fatigue, hypomagnesia, pain, neuropathy, anemia, and constipation. Reasons for dose-modifications were multi-factorial, and were primarily related to catheter complications and chemotherapy toxicities. The number of clinical encounters was high, and they were primarily related to admissions for inpatient IP chemotherapy and follow-up clinic visits.

CONCLUSIONS

Treatment-related toxicities and complications were common in women with ovarian cancer who received IP chemotherapy. Use of IP chemotherapy results in multiple clinical encounters, such as outpatient clinic visits and inpatient admissions. Nursing is a critical part of the interdisciplinary approach in caring for women treated with IP chemotherapy. Interdisciplinary teams with high levels of knowledge and skills related to IP chemotherapy administration are needed to manage treatment-related toxicities and complications, and support multiple clinical encounters during treatment.

Phase I trial of intraperitoneal pemetrexed, cisplatin, and paclitaxel in optimally debulked ovarian cancer

PURPOSE

This phase I trial evaluated intraperitoneal (i.p.) pemetrexed, cisplatin, and paclitaxel in optimally debulked ovarian cancer.

EXPERIMENTAL DESIGN

Dose escalation of day 1 i.p. pemetrexed accrued three patients to each of five dose levels (60-1,000 mg/m(2)), along with day 2 i.p. cisplatin (75 mg/m(2)) and day 8 i.p. paclitaxel (60 mg/m(2)). The goals were to determine maximum tolerated dose (MTD), 18-month progression-free survival (PFS), and pharmacokinetics of i.p. pemetrexed.

RESULTS

Cycles, given every 21 days, had an 80% 6-cycle completion rate. There was minimal grade III toxicity in the first 4 dose levels and remarkably an almost complete absence of peripheral neuropathy and alopecia. At the highest dose level, two of three patients experienced ≥ grade III and dose-limiting toxicity (DLT; hematologic, infection, gastrointestinal). There was a pharmacokinetic advantage for i.p. pemetrexed with an intraperitoneal:plasma area under the concentration-time curve ratio of 13-fold. Neither analysis of pharmacokinetic nor homocysteine levels explains the unexpected severity of toxicity in those two patients. On the basis of plasma C(24h) levels, the 42 cycles at ≥ 500 mg/m(2) i.p. pemetrexed without DLT, the MTD appears to be 500 mg/m(2). Median PFS is 30.1 months; 18-month PFS is 78.6% (median follow-up 22.4 months).

CONCLUSIONS

This i.p.-only regimen in front-line ovarian cancer is feasible with PFS in line with recent literature. We suggest phase II trials of this regimen in this population with i.p. pemetrexed at 500 mg/m(2). The favorable toxicity profile at doses <1,000 mg/m(2), which needs to be confirmed, appears to compare well with standard combination i.v./i.p. platinum/taxane chemotherapy in this disease.

Feasibility of a modified outpatient regimen of intravenous/intraperitoneal chemotherapy in optimally debulked stage III ovarian cancer patients: a GEICO study

OBJECTIVES

The objective of the study was to assess the feasibility, toxicity, and reasons for early discontinuation of a modified outpatient intraperitoneal/intravenous (IP/IV) chemotherapy regimen for the treatment of patients with optimally debulked stage III ovarian cancer.

METHODS

Between February 2006 and November 2008, 51 consecutive patients from Institutions of the Spanish Ovarian Cancer Group (GEICO) were treated with a modified outpatient IP chemotherapy regimen. Patients received IV paclitaxel 175 mg/m over 3 hours on day 1, followed by IP cisplatin 100 mg/m (or 75 mg/m according to the principal investigator's criteria) on day 2. On day 8, patients received IP paclitaxel 60 mg/m. To homogenize the IP administration and supportive measures, a GEICO guideline for IP chemotherapy was established. Patients were treated with the intention to receive 6 courses of chemotherapy every 21 days.

RESULTS

The median age of the patients was 49 years (range, 36-75 years), and most of them had papillary serous ovarian cancer (78%), International Federation of Gynecology and Obstetrics stage IIIC (76%). Thirty-nine patients completed 4 or more IP cycles, and 28 (61%) completed all 6 IP cycles. Twenty-two patients discontinued the IP/IV treatment, mainly because of chemotherapy toxicity (10 patients) and catheter-related complications (5 patients). The most prevalent grade 3/4 toxicities were neutropenia (14 patients; 30%) and gastrointestinal events (12 patients; 26%).

CONCLUSIONS

The GEICO outpatient modified regimen resulted in a lesser toxicity and a greater rate of treatment completion than previously reported. The accurate selection of patients and the administration following well-defined guidelines can increase the feasibility of IP chemotherapy administration.

Ports and complications for intraperitoneal chemotherapy delivery

Intraperitoneal access ports are essential to the delivery of chemotherapy agents into the peritoneal cavity of women with ovarian cancer, but their malfunction and adverse effects are frequently responsible for the failure to complete planned therapy. Complications, such as obstruction of the catheter, infection, leakage, rotation, retraction, and pain, together with bowel and vaginal perforation, cause delays in treatment, patient suffering and the expenditure of medical resources. A wide variety of ports have been used, including vascular access devices and intraperitoneal access devices. This paper reviews the development and use of ports for intraperitoneal chemotherapy, their complications and reported methods of prevention.

Phase II trial of intraperitoneal cisplatin combined with intravenous paclitaxel in patients with ovarian, primary peritoneal and fallopian tube cancer

BACKGROUND.: The objective of this study was to determine the toxicity of cisplatin-based intraperitoneal (IP)/intravenous (IV) treatment using a modified version of the IP/IV arm of GOG 172. METHODS.: Patients with stage IC-IV and recurrent ovarian cancer were treated with D1 paclitaxel (IV at 135 mg/m², 3-h infusion) and cisplatin (IP at 50 mg/m²) and D8 cisplatin (IP at 50 mg/m²) every 21 days for 6 cycles. The primary outcome measure was completion of 6 cycles. Toxicity was assessed using the CTCAE, v.3.0 as well as subjective reporting by patients after each cycle. RESULTS.: Twenty-one patients completed 87 cycles of chemotherapy with IP cisplatin and intravenous (IV) paclitaxel. Eleven patients (52%) were able to complete all 6 cycles. Reasons for failing to complete treatment: progression of disease (n=3), grade 3-4 ototoxicity (n=2), IP port complication (n=1), grade 4 fatigue (n=1), small bowel obstruction (n=1), severe paclitaxel reaction (n=1) and one patient refused further treatment (n=1). Dose reductions of paclitaxel (135 mg/m² to 110 mg/m²) were implemented per protocol for neutropenia (n=3) at a frequency of 3.75%. Dose delays were noted prior to 9 cycles for neutropenia (n=6), thrombocytopenia (n=1), elevated creatinine (n=1), and grade 3 rash (n=1) at a frequency of 10%. CONCLUSIONS.: Although only 52% of patients were able to complete 6 cycles of cisplatin-based IP chemotherapy, significant reductions in cisplatin-related metabolic toxicity and catheter-related complications were noted.

From randomized trial to practice: single institution experience using the GOG 172 i.p. chemotherapy regimen for ovarian cancer

BACKGROUND

The objective of the study was to evaluate completion rates and toxic effects of an i.p. chemotherapy regimen in a cross-section of nonselected patients with ovarian cancer (OC).

PATIENTS AND METHODS

All patients with stage IIIC OC consecutively operated at our institution from January 2006 to December 2007 were prospectively collected and analyzed.

RESULTS

Eighty-nine patients with stage IIIC OC optimally debulked were evaluated for this study. An i.p. port was primarily placed in 53 of 89 (60%), and i.p. chemotherapy was recommended in 55 patients. Reasons for not recommending i.p. chemotherapy in patients optimally debulked included postoperative complications (n = 7: 8%), poor nutritional/functional status (n = 5: 6%), and extensive surgery including bowel resection (n = 9: 10%). Thirty-three patients (33/55: 60%) recommended to receive i.p. chemotherapy-initiated i.p. treatment. Fifty-two percent of those beginning i.p. therapy (17/33) received three or more cycles with 36% (12/33) successfully completing six cycles. Reasons for discontinuation included grade 3-4 nephrotoxicity in 3 of 21 (14%), febrile neutropenia/sepsis in 3 of 21 (14%), port infection or malfunction in 8 of 21 (38%).

CONCLUSIONS

The i.p. chemotherapy regimen used in a consecutive cohort of patients carries could be completed in only a small percentage of patients. Less toxic regimens with higher acceptability should be considered.
