Combined systemic chronotherapy and hepatic artery infusion for the treatment of metastatic colorectal cancer confined to the liver 总被引:1,自引:0,他引:1
BACKGROUND: The optimal treatment of patients with metastatic colorectal cancer is still a clinical challenge. We describe the use of combined hepatic arterial infusion (HAI) of irinotecan (CPT-11) in conjunction with systemic chronotherapy infusion of 5-fluorouracil (5FU), folinic acid and carboplatin in patients with colorectal liver metastases. METHODS: Twenty-three patients with colorectal cancer and isolated liver metastases were enrolled in this trial. Intraoperative insertion of an intra-arterial catheter into the hepatic artery was accomplished during the colon operation (in cases of synchronous tumor) or as a separate procedure in colorectal cancer patients with newly diagnosed liver metastases. A systemic double-lumen double-chamber port was inserted via the subclavian vein as a separate procedure. The treatment plan included irinotecan given by intra-arterial infusion at 150 mg/m2 for 1 h. After 2 weeks of rest chronomodulated 5FU (700 mg/m(2); peak delivery rate at 04:00 h), leucovorin (175 mg/m2; peak delivery rate at 04:00 h) and carboplatin (40 mg/m2; peak delivery rate at 16:00 h) for 4 days was followed by 10 days' rest and then given again. After 10 days' rest another HAI was introduced using the same method. Each cycle of therapy included 2 HAI courses and 2 chronotherapy courses in between. After 2 complete cycles, patients were evaluated for their response with weekly accessed toxicity recording. RESULTS: Seven women, 8 men, median age 61 years (range 46-72). Eight patients had synchronous colon and hepatic disease and 7 patients had metachronous disease. Ten patients had previously been treated with 5FU and leucovorin while 5 patients were chemonaive. The mean number of cycles were 11.6 per patient (range 8-19). Partial response was achieved in 6 patients (40%) and was followed by laparoscopic radiofrequency ablation in 5 patients (33%). Disease stabilization was observed in 2 patients (13%) and disease progression in 7 patients (47%) mainly after previous chemotherapy failure. Side effects were infrequent and mild including grade 2 GIT complaints (5 patients), RUQ pain during HAI (9 patients) and grade 2 hematological complaints in 2 patients. CONCLUSION: A combined chemotherapy protocol (HAI and chronotherapy) with irinotecan (CPT-11) together with chronomodulated infusion of 5FU, folinic acid and carboplatin can be used in metastatic colorectal patients with a high efficacy rate and minor side effects especially in pretreated patients. 相似文献

PurposeTo compare the implant quality and clinical outcomes for patients treated with low and intermediate strength 125I seeds in prostate brachytherapy implants.Methods and MaterialsThis retrospective review included 390 consecutive patients treated with prostate brachytherapy from 1999 to 2006. The first 142 patients were implanted with source strengths lower than 0.415 U (0.327 mCi), with the subsequent 248 patients implanted with source strengths higher than 0.493 U (0.388 mCi). Clinical, dosimetric, toxicity, and outcome data were compared between these two cohorts of patients.ResultsDespite having similar prostate volumes, fewer sources (median, 95 vs. 113; p < 0.0001) and fewer needles (median, 23 vs. 29; p < 0.0001) were implanted in the intermediate strength cohort. The postimplant dosimetry demonstrated better quality implants in patients treated with intermediate strength sources (median D90, 160.0 Gy vs. 139.6 Gy; p < 0.0001), with greater dose inhomogeneity identified in the intermediate strength cohort of patients. A higher incidence of late rectal toxicity was identified in patients treated with intermediate strength sources despite lower rectal doses in this cohort. The biochemical relapse-free survival, prostate cancer survival, and overall survival were not significantly different between the two cohorts.ConclusionsThe transition from low to intermediate strength sources has led to fewer resources being used and improved postoperative dosimetry. Although there were more rectal complications identified in the intermediate strength cohort of patients in this analysis, there were no other significantly worse clinical or biochemical outcomes for patients implanted with intermediate strength sources. 相似文献

Ethical decision making in women's health presents a series of unique challenges that are exacerbated considerably in under-resourced settings. Severe constraints on both autonomy and resources highlight limitations of principle-based ethics for addressing ethical dilemmas. Other useful ethical "tools" are considered in the context of 2 cases that emphasize the challenges to ethical decision making in under-resourced settings. The cases confront traditional notions of patient autonomy, highlight pervasive issues with regard to allocation of resources, and demonstrate the difficulties encountered in the careful application of medical ethics. 相似文献

Objective
To establish an algorithm that incorporates sentinel lymph node (SLN) mapping to the surgical treatment of early cervical cancer, ensuring that lymph node (LN) metastases are accurately detected but minimizing the need for complete lymphadenectomy (LND).Methods
A prospectively maintained database of all patients who underwent SLN procedure followed by a complete bilateral pelvic LND for cervical cancer (FIGO stages IA1 with LVI to IIA) from 03/2003 to 09/2010 was analyzed. The surgical algorithm we evaluated included the following: 1. SLNs are removed and submitted to ultrastaging; 2. any suspicious LN is removed regardless of mapping; 3. if only unilateral mapping is noted, a contralateral side-specific pelvic LND is performed (including inter-iliac nodes); and 4. parametrectomy en bloc with primary tumor resection is done in all cases. We retrospectively applied the algorithm to determine how it would have performed.Results
One hundred twenty-two patients were included. Median SLN count was 3 and median total LN count was 20. At least one SLN was identified in 93% of cases (114/122), while optimal (bilateral) mapping was achieved in 75% of cases (91/122). SLN correctly diagnosed 21 of 25 patients with nodal spread. When the algorithm was applied, all patients with LN metastasis were detected; with optimal mapping, bilateral pelvic LND could have been avoided in 75% of cases.Conclusions
In the surgical treatment of early cervical cancer, the algorithm we propose allows for comprehensive detection of all patients with nodal disease and spares complete LND in the majority of cases. 相似文献956.
We report a newborn with methicillin-resistant Staphylococcus aureus mediated necrotizing fasciitis after Bacilli-Calmette-Guerin vaccination. Radical debridement of the affected area coupled with twice daily surgical honey dressing and intravenous vancomycin and clindamycin resulted in satisfactory healing. 相似文献

Cancer pain remains undertreated and a significant number of patients with cancer pain die from severe untreated pain. With increasing survival rate in cancer, the prevalence of cancer pain is also increasing in number. Though majority of patients with cancer pain can be effectively treated with conventional medical management, still a significant portion of patients required some form of interventional pain management techniques. Among the interventional techniques, intrathecal drug delivery is increasingly used in cancer pain management. Our objective of this article is to review literatures and clinical studies on intrathecal drug delivery system (IDDS) in cancer pain management and to provide updates on its use, precautions, contraindications, side effects and its management, socioeconomic consideration, and management of IDDS in difficult or uncommon situations. 相似文献

Social science research on lifestyle-related diseases typically focuses on patients' understandings and beliefs and takes the clinical risk for granted. We interviewed 30 healthy UK patients at high risk of heart disease, recruited from a family history trial at 2 weeks and 6 months after a discussion with a clinician about their risk, lifestyle and medications. The participants took four different paths: (i) pharmaceutical (most common, risk reduction with cholesterol lowering statins), (ii) mixed (statins and behaviour change), (iii) behavioural (behaviour change, focus on wellbeing) and (iv) 'lost' (no prevention, difficult social/personal circumstances). Drawing on Berg we argue that coronary heart disease (CHD) risk assessment technologies are formal tools that generate, rather than represent, high risk in a way that patients often experience lifestyle change as futile, because it rarely reduces their cholesterol to targets defined by the tools. We suggest social scientists studying incipient or 'proto-diseases', such as CHD risk, should not only focus on understandings but also investigate the technologies (and the associated guidelines, policies, clinical practice and pharmaceutical industry operations) that generate incipient diseases and patients' experiences of them. However, technologies do not determine experience and we also discuss elements that direct patients down other than the pharmaceutical path. 相似文献

Renal cell cancers are among the great mimics in surgery as they present with myriad symptoms unrelated to the renal cancer. This patient also interestingly had an incidental finding of porcelain gall bladder. 相似文献
