Hyperthermic intraperitoneal chemotherapy for the treatment of ovarian cancer: A brief overview of recent results
No full textOvarian cancer (OC) is the sixth most common neoplasm in women. Hyperthermic intraperitoneal chemotherapy (HIPEC), a strategy combining maximal cytoreductive surgery with maximal regional chemotherapy, has been proposed to treat OC. At present, less randomized trials has determined HIPEC real impact on patients with OC. In this brief report, we reported results of selected studies of treatment with HIPEC for patients with OC. Future prospects are conclusively discussed
Gemcitabine, oxaliplatin, and capecitabine (GEMOXEL) compared with gemcitabine alone in metastatic pancreatic cancer: a randomized phase II study
No full textBackground: Single-agent gemcitabine (GEM) has been considered for many years as the standard first-line treatment for advanced pancreatic cancer. However, recently, several studies reported encouraging activity and good tolerability for some combination regimens. Considering the apparently non-overlapping toxicity and the proved individual efficacy of GEM, oxaliplatin (l-OHP), and capecitabine (CAP), this randomized phase II study compared the activity and safety of the combination GEM, l-OHP, and CAP (GEMOXEL) versus GEM alone, in patients with metastatic pancreatic cancer. Materials and methods: The treatment in GEMOXEL arm consisted of GEM 1,000 mg/m2 as a 30-min intravenous infusion on days 1, 8, 15, 22, l-OHP 100 mg/m2 i.v. on day 2, and CAP 1,500 mg/m2/day in two divided doses on days 1-14, every 21 days (one cycle). In both treatment groups, GEM was administered weekly for seven consecutive weeks followed by 1-week rest for the first 8 weeks, and thereafter, GEM was continued on days 1, 8, 15, every 28 days. Chemotherapy was administered until disease progression or unacceptable toxicity. Results: Sixty-seven patients were enrolled in the study. Thirty-four were randomly assigned to GEMOXEL and 33 to GEM. At 4 months, disease control rate was 79.4 % with GEMOXEL versus 45.4 % with GEM (p = 0.004). The median progression-free survival was 6.8 months (95 % CI 5.3-7.3 months) in GEMOXEL arm and 3.7 months (95 % CI 2.9-4.7 months) in GEM arm (p < 0.001). The median OS was 11.9 months (95 % CI 10.6-12.9 months) in GEMOXEL arm and 7.1 months (95 % CI 5.5-9.1 months) in GEM arm (p < 0.001). Hematologic and non-hematologic toxicity was more severe with combination chemotherapy, yet still tolerable. No grade 4 adverse events were observed with either regimen. Conclusion: GEMOXEL regimen seemed to be safe and more efficient than the standard therapy with GEM alone in the treatment of metastatic pancreatic cancer
Role of chemotherapy in the treatment of metastatic castration-resistant prostate cancer patients who have progressed after abiraterone acetate
No full textAbiraterone acetate is a novel irreversible inhibitor of CYP17 that was recently approved for men with post-chemotherapy or chemo-naive castration-resistant prostate cancer. Unfortunately, this agent is not curative, and patients often ultimately develop resistance. However, men who progress after treatment with this new hormonal agent may be considered for another line of chemotherapy-based treatment. In 2004, docetaxel (D) and prednisone were found to improve survival compared with older regimens. More recently, cabazitaxel (C), a novel taxane chemotherapy, has been found to prolong survival in patients who exhibit disease progression during or after D chemotherapy. Here, we review the first clinical studies in which castration-resistant prostate cancer patients received chemotherapy with D or C after progression during abiraterone acetate treatment
28. Role of neoadjuvant chemotherapy with cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy for treatment of primary ovarian cancer with peritoneal carcinomatosis
No full textCytoreduction surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) as treatment choice of metastatic Urachal carcinoma
Get PDFIntroduction: Urachal carcinoma accounts for approximately 0.01 % of all adult malignancies and 1 % of bladder cancers. Its prognosis remains poor, with a 5 -year overall survival rate of less than 50 %. Presentation of case: A 51 -years -old black female, affected by peritoneal malignancies from urachal carcinoma, underwent multiple surgical cytoreduction (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) with different chemotherapy regimen, alternating with intravenous chemotherapy. Thirty-two months recurrence -free survival was registered, and overall survival was more than 5 years. Discussion: Our case suggests the importance of rigorous follow-up with both tumor marker testing (CEA) and imaging studies. Optimal debulking surgery plays a pivotal role in controlling primary and recurrent disease. The use of combined intraperitoneal and intravenous chemotherapy may have contributed to her long-term survival. Conclusion: CRS and HIPEC combined with intravenous chemotherapy may be potential candidates for treating patients with urachal carcinoma with peritoneal metastases. Our patient is a challenging case in daily surgical practice
Tolerability of cabazitaxel in patients with metastatic castration-resistant prostate cancer progressing after docetaxel and abiraterone acetate: a single-institution experience.
No full textBoth abiraterone acetate (AA) and cabazitaxel (Cbz) have been shown to prolong survival in patients with metastatic castration-resistant prostate cancer (mCRPC) progressing during or after docetaxel (D). Although no standard sequencing has been established as yet, Cbz has recently been proven to be active after AA. However, to date, few data are available on its safety in this setting. Therefore, the primary endpoint of this study was to investigate Cbz tolerability in mCRPC patients treated previously with D and AA. From April 2011 to the present, 43 mCRPC patients received AA after D at our institution. Of these, 22 patients were subsequently treated with Cbz and were evaluable for toxicity in the present retrospective study. Cbz was administered at a dose of 25 mg/m plus 10 mg oral prednisone every 3 weeks. Adverse events (AEs) were reported using the NCI CTCAE (National Cancer Institute Common Terminology Criteria for Adverse Events) version 3.0. Despite the advanced stage of disease and frailty of our study population, there were no unexpected side effects. The most common AEs were hematologic. Neutropenia was observed in nine (40.9%) patients and of grade≥3 in six (27.2%). No febrile neutropenia occurred. The most common nonhematologic AEs were diarrhea and asthenia, reported in eight (36.3%) and in five (22.7%) patients, respectively. In this setting, Cbz toxicity seems to be manageable and comparable with second-line Cbz. Therefore, our results seem to support the safety of Cbz as a third-line treatment for mCRPC patients
Angiogenesis inhibitors in gastric and gastroesophageal junction cancer
No full textDespite significant improvements in systemic chemotherapy during the past two decades, the prognosis of patients with advanced gastric and gastroesophageal junction adenocarcinoma remains poor. Because of molecular heterogeneity, it is essential to classify tumors based on the underlying oncogenic pathways and to develop targeted therapies acting on individual tumors. Unfortunately, although a number of molecular targets have been studied, very few of these agents can be used in a clinical setting. In this review, we summarize the available data on anti-angiogenic agents in advanced/metastatic gastric cancer
Low-Dose Estramustine Phosphate and Concomitant Low-Dose Acetylsalicylic Acid in Heavily Pretreated Patients With Advanced Castration-Resistant Prostate Cancer.
No full textBackground: The aim of this phase 2 study was to evaluate the activity and tolerability of low-dose estramustine phosphate (EMP) with concomitant low-dose acetylsalicylic acid (ASA) as a thromboprophylactic agent in heavily pretreated patients with advanced castration-resistant prostate cancer. Methods: Patients received 420 mg of oral EMP twice daily and oral ASA 100 mg once daily. The primary endpoint was prostate-specific antigen response. All of the patients had been previously treated with docetaxel and abiraterone acetate, and 12 had also received cabazitaxel. Results: Thirty-one patients were enrolled. Prostate-specific antigen response was observed in 9 patients (29.0%; 95% confidence interval [CI], 14-48). Median progression-free survival was 3.6 months (95% CI, 2.2-5.6), and median overall survival was 7.6 months (95% CI, 6.9-9.7). Treatment was generally well tolerated, and no grade 3/4 toxicity was observed. Ten patients (32.2%) had grade 2 nausea and vomiting. No cardiovascular event and no major bleeding occurred. No venous thromboembolism event was observed. Conclusion: Low-dose EMP with concomitant low-dose ASA seems to be a safe treatment option with some activity for patients with advanced castration-resistant prostate cancer who have been heavily pretreated
