Fast-track anesthesia and outcomes in hepatopancreatic cancer surgery: a retrospective analysis.

AIM: To assess the feasibility of a fast-track anesthesia protocol for hepatopancreatobiliary cancer surgery. METHODS: Retrospective analysis of consecutive sample of patients who underwent hepatopancreatic surgery for cancer for a period of 12 months in a high volume cancer center. Blended anesthesia was performed for most patients who were then observed in a recovery room area until achieving a safety score. RESULTS: Data of 163 patients were examined. Fifty-six and 107 patients underwent surgery for pancreatic cancer and liver surgery for primary tumor or metastases, respectively. Most patients were ASA 3. The mean durations of anesthesia and surgery were 322 min (SD 320) and 296 min (SD 133), respectively. Extubation was performed in the operating room in 125 patients. Post-operatory invasive ventilation was maintained in the recovery room in fifteen patients for a mean duration of 72.7 min (SD148.2). Only one patient was admitted to intensive care for 15 h. NIV was performed in three patients for a mean duration of 73.3 min (SD 15.3). The mean recovery room staying was 79 min (SD 80). The mean hospital postoperative stay was a mean of 8.1 days (SD 5.7). No complications were found in 144 patients. Globally, mortality rate was 3%. CONCLUSION: A program of fast-track anesthesia with a short stay in recovery room allowed to achieve a good outcome, limiting the costs of intensive care admission.

Palliative sedation outside a palliative care unit.

PURPOSE: The need of acute transition from an intensive care setting to an end-of-life setting requires collaboration and experience. Variable information exists on palliative sedation in traditional palliative care settings, including home care, hospices or palliative care units. MATERIALS: Four cases which required a rapid decision-making to alleviate suffering in patients close to death are described. RESULTS: Despite having different clinical pathways leading to intensive but medically non-beneficial treatments, patients were converted to a rapid transition of care in the unit where they had been admitted, due to different logistic reasons. An appropriate discussion with relatives about the short prognosis and the need to sedate for controlling suffering in the last hours of life was fundamental in preventing further suffering with intensive treatments. CONCLUSIONS: These clinical notes suggest that palliative care and end-of-life measures should be also expanded in other settings, where palliative care issues are traditionally not properly assessed, implementing the collaboration with other colleagues with different clinical extractions.

Methadone versus morphine for postoperative pain in patients undergoing surgery for gynecological cancer: A randomized controlled clinical trial.

STUDY OBJECTIVE: The aim of this study was to compare methadone and morphine for the management of postoperative. DESIGN: Open, controlled study. SETTING: Postoperative recovering area, ward. PATIENTS: Sixty-four patients, ASA I-III, undergoing gynecological surgery for cancer. INTERVENTIONS: Morphine or methadone 0.15 mg/kg given preoperatively. After operation an intravenous morphine or intravenous methadone infusion at doses of 12 mg/day was started. MEASUREMENTS: Pain intensity and opioid consumption. MAIN RESULTS: Methadone infusion provided a better analgesia in comparison with morphine infusion on the second day. Opioid consumption was significantly lower in the methadone group. No episodes of relevant desaturation or signs of respiratory depression were recorded. CONCLUSION: A preoperative bolus of methadone, followed by a continuous infusion of low doses post-operatively, provided a better analgesia, without adding risk of adverse effects, in comparison with morphine.

Supportive care services in hemato-oncology centers: a national survey.

BACKGROUND: In the field of hemato-oncology, there is paucity of data assessing models of integration between hemato-oncology and other partner specialties. The aim of this national survey was to gather information about the status of the integration of this kind of activity in hemato-oncologic units existing in Italy. METHODS: A national telephone survey was conducted to gather information about the status of the integration of hemato-oncologic and supportive care/anesthesiological services. From the national registry of hemato-oncology units, 149 centers were contacted by phone and a dedicated doctor was identified to gather information about the center through a telephone interview. RESULTS: Eighty-one centers (54.3 %) agreed to participate. A mean of 206 (SD 132) painful procedures/year/center were performed. No significant differences among regions and centers were found (P = 0.680). Of the centers, 41.9 % usually asked for anesthesiological consultation to perform painful procedures. No differences were found between the regions (P = 0.137). A mean of 1.8 (SD 1.2) days elapsed from the request to the procedure performance (P = 0.271). No differences among the regions were found (P = 0.350). A mean of 220 (SD 89) central venous vascular accesses/year/center were performed. No differences among regions were found (P = 0.170). No differences among the centers were found (P = 0.691). A mean of 1.8 (SD 1.2) days elapsed from the request to the performance of procedure. Of the centers, 64.2 % had a palliative care team. No differences among regions were found (P = 0.331). A mean of 31.5 (SD 12.2) consultations/year/center for pain control were required. No differences among the regions were found (P = 0.556). Of the centers, 30.8 % had some beds for palliative care. No differences among the regions were found (P = 0.641). Of the centers, 32 % had a hospice was available. No differences among regions were found (P = 0.298). CONCLUSION: Integration between hemato-oncology and other professionals is unlikely to be optimal in Italy. Such integration is complex and needs great efforts to solve several organizational problems.

Does pain intensity predict a poor opioid response in cancer patients?

AIM: The aim of this study was to test the hypothesis that initial pain intensity is not a predictive factor of poor opioid response in advanced cancer patients, as suggested by a recent work. METHODS: A secondary analysis of one-hundred-sixty-seven patients referred for treatment of cancer-related pain was conducted. Pain intensity at admission was recorded and patients were divided in three categories of pain intensity: mild, moderate and severe. Patients were offered a treatment with opioid dose titration, according to department policy. Data regarding opioid doses and pain intensity were collected after dose titration was completed. Four levels of opioid response were considered: (a) good pain control, with minimal opioid escalation and without relevant adverse effects; (b) good pain control requiring more aggressive opioid escalation, for example doubling the doses in four days; (c) adequate pain control associated with the occurrence of adverse effects; (d) poor pain control with adverse effects. RESULTS: Seventy-six, forty-four, forty-one and six patients showed a response a, b, c, and d, respectively. No correlation between baseline pain intensity categories and opioid response was found. Patients with response 'b' and 'd' showed higher values of OEImg. CONCLUSION: Baseline pain intensity does not predict the outcome after an appropriate opioid titration. It is likely that non-homogeneous pain treatment would have biased the outcome of a previous work.

The use of high doses of oxycodone in an acute palliative care unit.

A retrospective study of patients who were prescribed controlled-release oxycodone (CRO) in a period of 3 years (2006-2008) was performed. A total of 212 patients were prescribed at discharge CRO for background analgesia; 129, 43, and 40 patients were prescribed doses of oxycodone of less than 120 mg/day (group L), 120 to 240 mg/day (group M), and more than 240 mg/day (group L), respectively. No differences in gender, primary diagnosis, and pain mechanisms were found, but doses were significantly lower in older patients (P < .0005). At discharge, adverse effects were mild and only a minority of patients were switched to other opioids. This study demonstrated that CRO administered in larger doses was safe and effective, showing versatility and flexibility similar to morphine.

Morphine versus oxycodone in pancreatic cancer pain: a randomized controlled study.

OBJECTIVE: According to experimental findings, oxycodone (OX) could have some advantages over morphine (MO) in clinical models of visceral pain. It was hypothesized that OX could have some advantages over MO in terms of efficacy and dose escalation in pancreatic cancer pain. METHODS: Sixty patients with pancreatic cancer with a pain intensity rating of 4/10 who required opioids were included in the study. Patients were randomized to receive 30 mg/d of sustained release oral MO or sustained release oral OX (20 mg/d). Opioid doses were increased according to the clinical needs. Daily doses of opioids, pain and symptom intensity were recorded at admission (T0) and at weekly intervals for the subsequent 4 weeks (T1, T2, T3, and T4), with an extension at 8 weeks (T8). Opioid escalation index (OEI) as percentage (OEI %) and in mg (OEI mg) was calculated. RESULTS: Nineteen and 20 patients in groups OX and MO, respectively, were followed for the entire period of study (T4). No differences between groups were found in age (P=0.400), Karnofsky (P=0.667), or escalation indexes at T4 and T8 (OEImg, P=0.945 and OEI %, P=0.295). No statistical differences in pain and symptoms intensity between the groups were observed. CONCLUSION: OX and MO provided similar analgesia and adverse effects with similar escalating doses in patients with pancreatic cancer pain, resembling observations reported in the general cancer pain population. The experimental hypothesis that OX would be superior to MO in the clinical model of pancreatic cancer pain was not confirmed.

Breakthrough pain in oncology: a longitudinal study.

CONTEXT: Existing studies on breakthrough pain (BP) have reported different prevalence rates because of different settings, populations, and assessment methods. These studies have used cross-sectional designs, and the relationship of BP with analgesic treatment has not been evaluated. OBJECTIVES: The aim of this study was to longitudinally assess BP in cancer patients admitted to oncology units. METHODS: A consecutive sample of patients admitted to oncology centers was selected. At admission (T0), three months after admission (T3), and six months after admission (T6), data on background pain and BP were recorded. BP was assessed in terms of its intensity, duration, number of episodes, onset with movement, spontaneous relief after stopping activity, limitation of physical activity, and effectiveness of analgesics. RESULTS: Three hundred two patients completed the study. At T0, T3, and T6, 39%, 38%, and 33% patients, respectively, had continuous pain (P=0.294). Pain intensity significantly decreased (P=0.004 and 0.027 at T3 and T6, respectively). Most patients had BP at T0 (87.1%), T3 (80.9%), and T6 (73.2%), and there was a significant decrease in the prevalence of BP over time (P=0.016). Of 149 patients with BP, pain on movement was recorded in 43.6%, 43.4%, and 32.4% at T0, T3, and T6, respectively (P=0.228). Pain spontaneously decreased or ceased when stopping physical activity in 66%, 56%, and 62% at T0, T3, and T6, respectively (P=0.537). Pain on movement strongly limited physical activity in most patients. CONCLUSION: These data expand current information about BP and underline the need for a longitudinal assessment of a phenomenon that is invariably dependent on stage of disease, patient, and therapeutic factors.

Opioid switching and burst ketamine to improve the opioid response in patients with movement-related pain due to bone metastases.

OBJECTIVE: To improve opioid repsonse in patients with movement-related pain by using opioid switching adding a burst of ketamine. METHODS: Two patients with incident bone pain who had adverse effects with increasing doses of opioids were switched to methadone and a burst of 100 mg/d of ketamine for 2 consecutive days was added. RESULTS: Basal pain and pain on movement significantly improved. CONCLUSIONS: The development of breakthrough pain due to movement (incident pain), associated with bone metastases is so rapid that no medication as needed has such a short onset to parallel this temporal pattern of pain firing. Experimental studies have shown that bone metastases are characterized by a specific pattern of spinal hyperexcitation requiring higher doses of opioids. Optimization of basal opioid regimen may improve mobilization. However, adverse effects may more likely occur. The role of opioid switching and burst ketamine to further improve the opioid response has never been assessed in this context. Further studies in animals could confirm these preliminary data, with specific design to parallel this clinical context.

Effects of red blood cell transfusion on anemia-related symptoms in patients with cancer.

The aim of this study was to assess the effects of red blood cell transfusion, and the subsequent increase in hemoglobin values, on anemia-related symptoms in a cohort of patients with cancer with different survival times. A red blood cell transfusion was recommended to a consecutive sample of patients with hemoglobin levels of 8 +/- 0.5 g/dL. The number of units to be ordered was decided according the hemoglobin values with a mean target of increasing the hemoglobin values by approximately 2 g/dL. Hemoglobin values, anemia-related signs and symptoms, including well-being, fatigue, and dyspnea, were recorded at admission (T0), 1 day after the last transfusion (T1), and 15 days afterward (T2) by telephone contact or visit. Well-being, fatigue, and dyspnea were measured on a numerical scale of 0-10. Sixty-one patients were recruited in the period of study. One hundred thirty-three units of red blood cells were transfused (mean 2.18, 95% confidence interval [CI] 0.6). Complete data were available for 40 patients. Hemoglobin values and well-being significantly increased after transfusion (T1), maintaining acceptable values 15 days afterward (T2). Significant changes in fatigue and dyspnea were found immediately after transfusion, although the effect was partially lost 15 days after transfusion. No statistical differences were found between patients with different survival times. Fatigue was significantly lower in patients with longer survival times in comparison with patients with shorter survival times (p = 0.04). Blood transfusion in patients with hemoglobin values of approximately 8 g/dL improved anemia-related symptoms on a short-term basis. This benefit is independent of the stage of disease and survival. However, the effects on dyspnea and fatigue tend to decrease within 15 days, despite the maintenance of hemoglobin values attained after transfusions, suggesting that other factors may play a role.

Tools for identifying cancer pain of predominantly neuropathic origin and opioid responsiveness in cancer patients.

UNLABELLED: Neuropathic pain (NP) is a difficult issue, particularly in cancer which is a dynamic condition where multiple pain etiologies are concomitantly present. Cancer pain is often labeled as mixed mechanism pain and is not easily classified as exclusively nociceptive or NP. The aim of this study was to explore the value of evaluation tools such as Neuropathic Pain Questionnaire (NPQ), complete and short form (NPQ-SF), Leeds Assessment of Neuropathic Signs and Symptoms (LANSS) and Neuropathic Pain Symptom Inventory (NPSI). The secondary outcome was to evaluate the response to opioid titration, according to the hierarchical classification of definite, possible and unlikely NP. A consecutive sample of patients referred for treatment of cancer-related pain were eligible for participation in the study. The inclusion criterion was uncontrolled cancer pain requiring adjustment of opioid therapy. Patients were clinically classified into tertiles based according to graded evidence of nervous system lesion: definite NP, possible NP, or unlikely NP. Pain and symptoms intensities were measured before (T0) and at the end of opioid titration (T1). Patients were titrated with escalating doses of opioids, supported by symptomatic drugs, changing the route of administration, or by opioid switching according to the clinical response. At T1 the opioid response was clinically graded from 1 to 4. Opioid escalation index was calculated. A single independent investigator, blinded to the clinical assessment and treatment, collected data from NPQ, NPQ-SF, LANSS Pain Scale, and NPSI. One hundred and sixty-seven patients concluded the study. Sixty, thirty-six, and seventy-one patients were clinically assessed as having definite NP, possible NP, or unlikely NP, respectively. A relationship between the values of the assessment tools and clinician rating was found. Patients with the highest values of assessment tools were also more likely to be clinically labeled as definite NP, although sensibility and specificity were low. Patients with a clinical diagnosis of definite NP, possible NP, or unlikely NP showed significant differences in opioid response (P < .0005). Patients with "unlikely NP" had a lower pain intensity at T1 (P < .05), and patients with "definite NP" required more intensive treatment. Patients requiring more aggressive treatment showed significantly higher values of Opioid Escalation Index (OEI)mg. PERSPECTIVE: Screening tools may provide a basis to suggest a common language in cancer pain syndromes. A hierarchical grouping seems to be more flexible and fits cancer patient characteristics. This study also confirms that opioids are clinically effective in "definite NP" conditions although a more aggressive treatment requiring careful utilization of opioids and symptomatic drugs is strictly necessary.

High-dose furosemide and small-volume hypertonic saline solution infusion for the treatment of leg edema in advanced cancer patients.

Peripheral edema is a common feature in populations with advanced cancer, although it is seldom recognized. Diuretics are commonly employed and may show some benefit, but there are insufficient clinical trial data to draw useful conclusions about their clinical use. The aim of this prospective study was to evaluate the efficacy and tolerability of high-dose furosemide and small-volume hypertonic saline solution infusion in reducing leg edema in patients with advanced cancer treated unsuccessfully with diuretics. A prospective study was performed in a consecutive sample of 24 patients admitted to a pain relief and palliative care unit over a period of 18 months. To be eligible to enter the trial, advanced cancer patients had to have diffuse bilateral leg edema unresponsive to common doses of diuretics. A solution of 60 mEq of NaCl, 250 mg of furosemide, and 150 mL of normal saline were infused over 20 minutes. The treatment was repeated twice a day for two days and eventually continued on the basis of the clinical outcome. Circumferences were measured at the foot, ankle, calf, and thigh before starting the treatment (T(0)) and at intervals of 24 hours (T(1) and so on). At the same intervals, diuresis was determined. Patients were asked to score their sensation of leg weakness/heaviness on a numerical scale from 0 to 10, before (T(0)) and after the treatment (T(end)). An appreciable improvement in the sensation of weakness/heaviness (score reduction of at least two points) was recorded in all the patients. A small decrease in leg circumferences at the different sites was found, and a mean of 3600 mL/day of diuresis was recorded. These observations suggest that high-dose furosemide and small-volume saline may be an effective strategy for the treatment of peripheral edema in patients with advanced cancer.

Controlled sedation for refractory symptoms in dying patients.

Terminally ill cancer patients near the end of life may experience intolerable suffering refractory to palliative treatment. Although sedation is considered to be an effective treatment when aggressive efforts fail to provide relief in terminally ill patients, it remains controversial. The aim of this study was to assess the need and effectiveness of sedation in dying patients with intractable symptoms, and the thoughts of relatives regarding sedation. A prospective cohort study was performed on a consecutive sample of dying patients admitted to an acute pain relief and palliative care unit within a cancer center. Indications for sedation, opioid and midazolam doses, level of delirium and sedation, nutrition, hydration, rattle, inability to cough and swallow, pharyngeal aspiration, duration of sedation and survival, and use of anticholinergics or other drugs were recorded. Family members were interviewed. Forty-two of 77 dying patients were sedated, and had a longer survival than those who were not sedated (P=0.003). Prevalent indications for sedation were dyspnea and/or delirium. Twelve patients began with an intermediate sedation, and 38 patients started with definitive sedation. The median sedation duration was 22 hours. Opioid doses did not change during sedation. Agitated delirium significantly decreased with increasing doses of midazolam, whereas the capacity to communicate concomitantly decreased. Interviewed relatives were actively involved in the process of end-of-life care, and the decision to sedate, and the efficacy of sedation, were considered appropriate by almost all relatives. Controlled sedation is successful in dying patients with untreatable symptoms, did not hasten death, and yielded satisfactory results for relatives. This study also points to the importance of palliative care and the experience of professionals skilled in both symptom control and end-of-life care.

Peritoneal catheter for continuous drainage of ascites in advanced cancer patients.

INTRODUCTION: Advanced cancer patients with refractory ascites do not often respond to dietary sodium restriction and diuretics. While paracentesis is effective, the condition invariably recurs, necessitating repeated procedures. A continuous peritoneal drainage by an indwelling catheter has been reported to be hugely beneficial symptomatically, avoiding the hazards and disadvantages of multiple repeated procedures and direct and indirect costs. MATERIALS AND METHODS: Forty patients with advanced cancer patients admitted to an acute pain relief and palliative care unit, who presented symptomatic ascites, were recruited for continuous drainage of peritoneal fluid. A central venous catheter set for Seldinger technique was used. Technical failure was defined as an unsuccessful drainage of fluid through the catheter. Immediate and late complications, including hypotension, haemorrhage, tube blockage, dislodgment and sepsis were recorded. Record of daily drainage during admission were noted. At time of discharge, patients were asked to rate their global symptom burden as improved, unchanged or worsened. The follow-up was performed with frequent phone contacts or day-hospital admission in case of problems. RESULTS: The mean patients' age was 68 years, and 21 were men. Patients were receiving unsuccessfully a mean dose of furosemide of 32 mg/day. The technique was not painful and was easily accepted by patients. Insertion was technically successful in almost all patients. Mean admission time was 5.5 days (range 2-14), and the mean drained volume during admission was 8,499 ml (range 800-20,700), 2,850 ml (300-4,200) being drained on the first 24 h. No immediate complications were recorded. Six patients died during admission. The mean survival was 38.9 days (range 1-120). Of the 34 patients who were discharged home, 22 patients stated that symptom burden had improved, while in 10 patients symptom burden did not change or worsened, probably due to the advanced status of diseases and multiple contributing factors. Five, two, and one patients required skin sutures at 1, 2 and 3 months, respectively. About one third of patients had mechanical problems, some of them requiring a catheter replacement. No infection was recorded. CONCLUSION: In conclusion, a permanent peritoneal catheter was a valuable method to remove abdominal fluids and reduce symptom burden attributable to ascites and was also easy to use at home. Complication rate was acceptable and balanced by the benefits of the technique which avoided frequent paracentesis and associated complications.

Intrathecal treatment in cancer patients unresponsive to multiple trials of systemic opioids.

The aim of this study was to evaluate the clinical response to a combination of intrathecal morphine and levobupivacaine in advanced cancer patients who were highly opioid-tolerant, being previously treated with multiple opioid trials unsuccessfully. Initial intrathecal morphine dose was calculated from the previous opioid consumption using a morphine oral-intrathecal ratio of 100:1. Then, doses of both drugs were modified during the treatment according to the clinical needs and balanced with adverse effects. Fifty-five patients were assessed during admission, before starting the intrathecal treatment, during the titration phase, and followed up to death, by frequent phone contacts or visits, as available. Pain and symptom intensities were recorded before starting the intrathecal treatment (T0), at time of hospital discharge (T dis), and then at 1 month (T1), 3 months (T3), 6 months (T6) intervals, and the last observation, at least 1 week before death (T death). Fifty-five patients were selected for starting an intrathecal treatment. Thirty-two patients were males. The mean age was 60 years (95% CI 57-63), and 65.4% of patients were under 65 years. The most frequent indication was the presence of adverse effects and poor pain control. Complete data with adequate follow-up until death were available in 45 patients. Statistical differences in pain intensity were found at the different time intervals examined until death. Statistical decreases in the intensity of drowsiness and confusion were found until 1 month after starting intrathecal therapy. Statistical differences were found in daily intrathecal morphine doses, with a 3-fold increase at time of hospital discharge. Subsequently, further increases in doses were not significant. Conversely, systemic opioids, expressed as oral morphine equivalents, significantly decreased at all the intervals examined until death. Early complications included mild bleeding in 2 patients, without consequences, headache in 4 patients, bladder catheterization in 6 patients, reoperation for bleeding or changes of catheter position in 4 patients, unrelated death in 1 patient, and stroke in another 1. Late complications included local infection in 2 patients, and discontinuation of intrathecal therapy due to spinal compression. In patients who had received multiple trial of opioids and routes of administration, the intrathecal treatment started with an oral-intrathecal morphine conversion ratio of 100:1, and local anesthetics at the most convenient clinical doses provided a long-term improvement of analgesia, with a decrease in adverse effects and opioid consumption until death.

Injustifiable use of gastroprotection in advanced cancer patients.

The aim of this survey was to prospectively collect data about gastroprotector prescription at admission of an acute pain relief and palliative care unit. An observational survey was performed on three-hundred consecutive patients. Reasons for admission, concomitant treatment and use of drugs were recorded at admission. About 60.6% patients had been prescribed proton pump inhibitors or anti-H2 receptors agents. Of these patients, possible risk factors were nonsteroidal anti-inflammatory drugs (41, 22.5%), corticosteroids (43, 23.6%), age > 75 years (27, 14.8%). In only 25 admissions (13.7%) prescription corresponded to Italian drug agency recommendations with an odds ratio of an off-label prescription of 7.28. In a relatively high percentage of admissions (55%), patients receiving gastroprotectors were on chemotherapy, with an odds ratio of 1.42. This survey showed that gastroprotectors are often prescribed regardless of Health Care System regulations, as only a minority of patients satisfied the requirements of an appropriate and refundable prescription. The attitudes of oncologists who prescribe gastroprotectors for a putative protective effects are not supported by evidence. Health Care Service in Italy should be aware of these problems to improve the strategies of budgeting the drug expense in a better way or providing further guidelines based on studies able to demonstrate the real cost-benefit ratio of this class of drugs.
